     DETAILED DESCRIPTION OF THE DISCLOSURE 
     Embodiments of the present application will be described below in detail. Examples of the embodiments are illustrated in the accompanying drawings, where the same or similar reference numerals throughout the specification refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be illustrative, but should not be construed as limiting the present application. 
     The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. In one embodiment, they are only examples, and are not intended to limit the present application. In addition, the present application may repeat reference numbers and/or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not in itself indicate the relationship between the various embodiments and/or settings discussed. In addition, the present application provides examples of various specific processes and materials, but the applicability of other processes and/or the use of other materials. 
     It is found by the inventor in the actual life that the cleaning apparatus in the related art usually requires the user to manually dump the dust, which causes high labor intensity. Moreover, since the cleaning apparatus in the related art is designed to be hand-held and portable and its dust storage space is small, it is inconvenient to go back and forth between a cleaned place and a place where the dust is to be dumped. In addition, there are still some drawbacks in cleaning the dust cup component. For example, hands may get dirty when the user opens a bottom lid of the dust cup. For another example, some dust will be adsorbed on the filter element. Since the dust adsorbed on the filter element cannot be removed when the dust is dumped in a normal way, it is difficult to clean the filter element and the filter element needs to be cleaned subsequently, causing cumbersome operation. Therefore, the present application provides a dust accumulation base and a cleaning apparatus assembly with the same, which can solve at least one of the above problems. 
     The dust accumulation base A according to the embodiment of the first aspect of the present application will be described below with reference to drawings. 
     As shown in  FIGS. 1 and 2 , the dust accumulation base A includes a support part A 1  and a dust collection part A 2 . The support part A 1  is configured to support the cleaning apparatus B, and the dust collection part A 2  is provided therein with a dust collection part for collecting dust in the cleaning apparatus B. The dust accumulation base A has a dust inlet A 01  in communication with the dust collection chamber A 22 . The support part A 1  is configured to support the cleaning apparatus B, and the support part A 1  is provided with an avoidance area A 7  that can accommodate or avoid a suction accessory B 03  of the cleaning apparatus B. 
     Therefore, when the cleaning apparatus B is fitted on the dust accumulation base A, the suction accessory B 03  can be placed in the avoidance area A 7 , instead of detaching the suction accessory B 03  from the cleaning apparatus B to install the cleaning apparatus B, thus avoiding the process of removing the accessory before the dust is dumped from the cleaning apparatus. In some embodiments, the suction accessory B 03  on the cleaning apparatus B is not detachable. For example, in the example of  FIG. 6 , a main body B 0  of the cleaning apparatus B has an air inlet pipe  01 , and the air inlet pipe  01  is not removable. The air inlet pipe  01  can be placed in the avoidance area A 7 , so that the main body B 0  can be securely fitted on the support part A 1 . In the example of  FIG. 6 , the cleaning apparatus B further includes another suction accessory B 03  detachably coupled to the main body B 0 , for example, the suction accessory B 03  can be inserted in and coupled to the air inlet pipe  01 ; the suction accessory B 03  is long, and the top of the suction accessory B 03  can also be placed in the avoidance area A 7 . 
     Since the suction accessory B 03  is placed in the avoidance area A 7 , instead of being hung outside the support part A 1 , a case where the whole apparatus is not stable when the dust is dumped due to the external suspension of the suction accessory B 03  can be avoided. In this way, the stability and safety of the cleaning apparatus B supported by the dust accumulation base A can be improved. 
     Moreover, because the cleaning apparatus B is mainly supported by the support part A 1 , and the avoidance area A 7  is configured to avoid the suction accessory B 03 , the avoidance area A 7  will not affect the stability of the cleaning apparatus B, that is, the cleaning apparatus B can be installed steadily when the suction accessory B 03  is not removed and when the suction accessory B 03  is removed. Therefore, the user can directly fit the cleaning apparatus B on the dust accumulation base A after use, without having to consider whether to install or remove a certain suction accessory. 
     In addition, since the dust accumulation base A can stably support the cleaning apparatus B, the user can fit the cleaning apparatus B on the dust accumulation base A after using the cleaning apparatus B. The dust accumulation base A is both a place for collecting dust for the cleaning apparatus B and a place for storing the cleaning apparatus B. The dust can be removed immediately every time the cleaning apparatus B is stored in the dust accumulation base, avoiding a case where the user forgets to dump the dust after using the cleaning apparatus B. In this way, the user avoids the trouble of dumping the dust before using the cleaning apparatus B next time. 
     It should be noted that the type of the cleaning apparatus B according to the embodiment of the present application is not limited, for example, it can be a hand-held vacuum cleaner, a hand-held push-rod vacuum cleaner, a mopping vacuum cleaner, or the like. After the type of cleaning apparatus B is determined, the types of the suction accessory B 03  of the cleaning apparatus B. 
     For example, when the cleaning apparatus B is a hand-held push-rod vacuum cleaner, the cleaning apparatus B may include a push rod (not shown in the figure), a floor brush (not shown in the figure), and the like in addition to the dust cup component B 1 . For another example, when the cleaning apparatus B is a mopping vacuum cleaner, the cleaning apparatus B may include a hose (not shown in the figure), a floor brush (not shown in the figure), and the like in addition to the dust cup component B 1 . In addition, according to different cleaning goals, different cleaning apparatuses B use different suction accessories B 03 , including straight pipe heads, hose heads, brush heads, and the like; therefore, the specific shape of the dust accumulation base A should also be adapted to the type of cleaning apparatus B. 
     Therefore, in the dust accumulation base A according to the embodiment of the present application, the support part A 1  can be configured to hold the cleaning apparatus B and the dust collection part A 2  can be configured to collect dust in the cleaning apparatus B, thus achieving powerful functions. When the dust storage space in the cleaning apparatus B is small, the user can place the dust accumulation base A closer to the cleaned place, so that the cleaning apparatus B can dump dust in the dust accumulation base A at any time, preventing the user from repeatedly going back and forth to the indoor dust dumping place (such as a bathroom, a kitchen or the like in a house), and reducing the user&#39;s labor intensity. 
     In some embodiments, due to the structure of the filter element B 13  in the cleaning apparatus B, wire entangling hardly occurs; or the environment where the cleaning apparatus B is used basically has granular and flocculent dust but has less hair and silk trash. For those cleaning apparatuses B, dust can be dumped very simply. The cleaning apparatus B is fitted on the dust accumulation base A, and after the dust outlet B 1211  of the cleaning apparatus B and the dust inlet A 01  of the dust accumulation base A are fitted in place, the dust in the cleaning apparatus B can be directly affected by gravity and dumped out. Sometimes, by knocking the dust cup component B 1 , the dust dumping effect can be improved. 
     In other embodiments, as shown in  FIG. 3 , the dust collection part A 2  also has a motor chamber A 21 , and the dust accumulation base A further includes a suction device A 3  arranged in the motor chamber A 21 . The suction device A 3  is configured to cause the dust collection chamber A 22  to suck the dust from the cleaning apparatus B; that is, after the suction device A 3  is started, negative pressure can be generated in the dust collection chamber A 22 , and the dust in the cleaning apparatus B can be sucked in. Under the action of the suction device A 3 , the dust in the cleaning apparatus B can be sucked into the dust collection chamber A 22  more effectively and quickly, improving the dust removal rate of the filter element B 13  in the cleaning apparatus B, improving the overall dust dumping effect of the cleaning apparatus B, avoiding separate cleaning of the filter element B 13  by the user, and greatly reducing the user&#39;s labor intensity. 
     Therefore, in the dust accumulation base A according to the embodiment of the present application, the support part A 1  can be configured to hold the cleaning apparatus B and the dust collection part A 2  and the suction device A 3  can be configured to collect dust in the cleaning apparatus B, thus achieving powerful functions. Moreover, under the action of the suction device A 3 , the dust in the cleaning apparatus B can be sucked into the dust collection chamber A 22  more effectively and quickly, improving the dust removal rate of the filter element B 13  in the cleaning apparatus B, improving the overall dust dumping effect of the cleaning apparatus B, avoiding separate cleaning of the filter element B 13  by the user, and greatly reducing the user&#39;s labor intensity. 
     In addition, when the dust storage space in the cleaning apparatus B is small, the user can place the dust accumulation base A closer to the cleaned place, so that the cleaning apparatus B can dump dust in the dust accumulation base A at any time, preventing the user from repeatedly going back and forth to the indoor dust dumping place (such as a bathroom, a kitchen or the like in a house) and reducing the user&#39;s labor intensity. 
     It can be understood that the specific structure and working principle of the suction device A 3 ; for example, the suction device A 3  may be configured as a fan with a motor, a vacuum pump or the like, which will not be repeated here. In addition, in order to realize the communication between the motor chamber A 21  and the dust collection chamber A 22 , a chamber wall of the motor chamber A 21  has an air passage hole A 211 . In order to ensure the normal operation of the suction device A 3 , since the chamber wall of the motor chamber A 21  has an exhaust hole A 212 , the dust chamber A 22  can suck dirty air in when the suction device A 3  is working. Clean air separated in the dust chamber A 22  can enter the motor chamber A 21  through the air passage hole A 211 , and then be discharged out of the motor chamber A 21  through the exhaust hole A 212 . 
     In other embodiments, the cleaning apparatus B can also be configured to blow air to the dust accumulation base A, so that the dust in the cleaning apparatus B can also be brought into the dust collection chamber A 22  when the air flows from the cleaning apparatus B to the dust collection chamber A 22 . 
     In some embodiments, as shown in  FIG. 1 , the support part A 1  is coupled to the dust collection part A 2  through a strut A 40 ; that is, the support part A 1  is supported by the dust collection part A 2 . Therefore, when the cleaning apparatus B is fitted on the support part A 1 , the dust collection part A 2  has to bear both the weight of the dust accumulation base A and the weight of the cleaning apparatus B. Therefore, one of the key points of the design of this structure is to ensure that the structure layout of the dust accumulation base A is reasonable, to avoid the unbalance of the center of gravity after the cleaning apparatus B is fitted. 
     In some embodiments, the support part A 1  and the dust collection part A 2  are separate parts, and the support part A 1  is fixed to an external object by a supporting and fixing assembly (not shown in the figure). The external object here can be a building wall, a desk, a cabinet or other objects. The supporting and fixing assembly may be configured as a screw fastening structure, an adhesive structure, a suction cup structure, or the like, and the structural form of the support part A 1  fixed to an external object is not limited here. 
     When the support part A 1  is coupled to the dust collection part A 2  through the strut A 40 , in some specific examples, as shown in  FIG. 2 , the support part A 1  and the dust collection part A 2  are detachably connected through the strut A 40 . In this way, the support part A 1  and the dust collection part A 2  are split into two parts at the strut  40 , facilitating the storage, packaging and transportation of the dust accumulation base A. In some examples, the dust collection part A 2  is provided with a storage chamber for accommodating the support part A 1 , and the support part A 1  is taken out and installed during use. Here, it should be noted that the specific structure of the strut  40  is not limited as long as the support part A 1  and the dust collection part A 2  are detachably connected. 
     In some other examples, the support part A 1  and the dust collection part A 2  are connected by the strut A 40  in an adjustable distance, so that the strut A 40  can be adjusted to better meet the needs of the storage of the suction accessory B 03  when the suction accessory B 03  on the cleaning apparatus B is too long or too short. For example, the strut A 40  is configured as a soft rod. When the support part A 1  is fixed to the external object by the supporting and fixing assembly, the soft rod can be adjusted by way of stretching out and retracting through the fixed position of the support part A 1 . For another example, the strut A 40  may also be a rigid rod. After being adjusted by way of stretching out and retracting, the strut A 40  is locked by a locking structure, and there is no limitation for this here. 
     In other examples, the strut A 40  can be adjusted in height and can be detached. Since the strut can be disassembled and assembled, and also can be adjusted in height as required, better use convenience can be achieved. 
     In some embodiments, as shown in  FIGS. 2 and 3 , the dust inlet A 01  may be formed in the support part A 1 , and the support part A 1  has a dust passage chamber A 11  communicating the dust inlet A 01  with the dust collection chamber A 22 . Therefore, the dust collection part A 2  can suck the dust from the cleaning apparatus B through the dust inlet A 01  and the dust passage chamber A 11  in the support part A 1 , so that the support part A 1  can be used for not only supporting the cleaning apparatus B, but also sucking dust. In this way, the structure of the dust accumulation base A becomes more compact and smaller. In one embodiment, the present application is not limited to this, and the dust inlet A 01  is not limited to being formed on the support part A 1 . For example, the dust inlet A 01  may also be arranged on the dust collection part A 2 , which will not be detailed here. 
     In one embodiment, the support part A 1  includes support sub-parts A 10  for supporting the cleaning apparatus B, and an avoidance area A 7  is defined between at least two support sub-parts A 10 . The avoidance area A 7  is open on one horizontal side (i.e., a side in a horizontal direction; e.g., the front side shown in  FIG. 2 ) and on two vertical sides (i.e., two sides in a vertical direction; e.g., the upper and lower sides in  FIG. 2 ) respectively to avoid the suction accessory B 03  of the cleaning apparatus B. In this way, the cleaning apparatus B can be supported by at least two support sub-parts A 10  on the two horizontal sides of the avoidance area A 7 , thus realizing more stable supporting. 
     In one embodiment, in the embodiments of the present application, the shape of the avoidance area A 7  is not limited to this, and the avoidance area A 7  can also be formed as a groove in the center of the support part A 1 , or the avoidance area A 7  is open on two horizontal sides. 
     In one embodiment, the top surface of the support part A 1  is provided with dust inlets A 01  on two sides of the avoidance area A 7 . In one embodiment, the top surface of each support sub-part A 10  is provided with a dust inlet A 01 , and the top surface of the support sub-part A 10  is configured to position the end surface of the dust cup component B 1 . In this way, the cleaning apparatus B can be positioned and conduct dust cleaning no matter on which support sub-part A 10  the cleaning apparatus B is fitted. Here, a surface shape adapted to the end surface of the dust cup component B 1  is formed on the top surface of the support sub-part A 10 , and the dust cup component B 1  can be positioned to a certain extent through surface fitting, which is beneficial to the quick alignment and connection of the dust inlet A 01  and the dust outlet B 1211  and avoids dust leakage caused by tilting. 
     In one embodiment, as shown in  FIG. 1 , the support part A 1  may be located above the dust collection part A 2 , and the dust accumulation base A may also include a garbage pipe A 4 . In conjunction with  FIG. 3 , the garbage pipe A 4  extends vertically and communicates the dust collection chamber A 22  with the dust passage chamber A 11 , and thus the dust in the dust passage chamber A 11  can be supplied to the dust collection chamber A 22  through the garbage pipe A 4 . Thus, by arranging the support part A 1  above the dust collection part A 2 , and connecting the support part A 1  to the dust collection part A 2  through the garbage pipe A 4  extending in the vertical direction, the support part A 1  can supply dust to the dust collection part A 2  and the height of the support part A 1  can be increased so that the user can place the cleaning apparatus B on the support part A 1  without bending over. 
     In some embodiments, as shown in  FIGS. 2 and 3 , the support part A 1  and the dust collection part A 2  may be detachably connected through the garbage pipe A 4 . The support part A 1  and the dust collection part A 2  can be split into two parts from the garbage pipe A 4 , thus facilitating the storage, packaging and transportation of the dust accumulation base A. Here, it should be noted that the specific structural form of the garbage pipe A 4  is not limited as long as the support part A 1  and the dust collection part A 2  can be detachedly connected. 
     For example, in the example shown in  FIG. 2 , the garbage pipe A 4  may include a first sub-pipe A 41 , a second sub-pipe A 42 , and a third sub-pipe A 43  that are sequentially connected from top to bottom. The first sub-pipe A 41  can be integrated with the support part A 1 , the third sub-pipe A 43  can be integrated with the dust collection part A 2 , and the second sub-pipe A 42  can be inserted in the first sub-pipe A 41  and the third sub-pipe A 43  respectively. Therefore, the support part A 1  and the dust collection part A 2  can be detachably connected through the garbage pipe A 4  in a simple and effective manner. 
     In one embodiment, the structure of the garbage pipe A 4  is not limited to this. For example, in other embodiments, the second sub-pipe A 42  can also be omitted, and the first sub-pipe A 41  and the third sub-pipe A 43  can be directly connected in an inserting way. In addition, in other embodiments of the present application, the garbage pipe A 4  can also be configured as a stretchable sleeve structure, so that the height of the support part A 1  can be changed by adjusting the length of the garbage pipe A 4 , to better meet the actual needs of users of different heights. 
     In some embodiments, as shown in  FIG. 2 , the support part A 1  may include a first support sub-part A 102  and a second support sub-part A 103 , and the avoidance area A 7  which is open on a horizontal side (i.e., a side in a horizontal direction; e.g., the front side shown in  FIG. 2 ) and on two vertical sides (i.e., two sides in a vertical direction; e.g., the upper side and lower side in  FIG. 2 ) is defined between the first support sub-part A 102  and the second support sub-part A 103 . 
     In one embodiment, in other embodiments, the support part A 1  may also include more support sub-parts A 10 , and support sub-parts A 10  are coupled to form a support part A 1 . Among the multiple support sub-parts A 10 , the avoidance area A 7  can be formed between two suitable support sub-parts A 10 , and one avoidance area A 7  or multiple avoidance areas A 7  may be formed. 
     In some embodiments, as shown in  FIG. 2 , when the support part A 1  is located above the dust collection part A 2  and the support part A 1  has the avoidance area A 7 , the dust collection part A 2  may also have an avoidance recess A 24 , and the avoidance recess A 24  is configured to avoid a downwardly extending push rod, a floor brush and other suction accessories B 03 ; therefore, there is no need to deliberately configure the dust collection part A 2  as a thin box shape as a whole in order to avoid the suction accessory B 03 . Therefore, by providing the avoidance recess A 24  on the dust collection part A 2 , the dust collection part A 2  can be configured in any shape as required, to ensure that the dust collection part A 2  can be stably supported on the ground on the one hand and that the dust collection part A 2  has a dust collection chamber A 22  with sufficient capacity on the other hand. 
     In one embodiment, as shown in  FIG. 2 , the avoidance recess A 24  is arranged on the side wall of the dust collection part A 2  to avoid the suction accessory B 03  having a long tube and a long brush head. Here, since the avoidance recess A 24  is formed on the side wall of the dust collection part A 2 , the portion of the dust collection part A 2  with the avoidance recess A 24  is thin, and the portion of the dust collection part A 2  without the avoidance recess A 24  is thick. In this way, the case where the dust collection part A 2  is relatively thick as a whole and thus occupies too much space can be avoided on the one hand, and the avoidance recess A 24  can form a certain limit for the suction accessory B 03  on the other hand. 
     In one embodiment, as shown in  FIG. 2 , the avoidance recess A 24  is narrow at the top and wide at the bottom, and the avoidance recess A 24  is provided with an upwardly penetrating avoidance opening A 241  corresponding to the avoidance area A 7 . Here, due to arrangement of the avoidance opening A 241 , the long tube can extend into the avoidance recess A 24  conveniently. The avoidance recess A 24  is formed into a shape with a narrow top and a wide bottom, so that the avoidance recess A 24  can position the suction accessory B 03  (such as a brush head) with a wide end. In this way, the avoidance recess A 24  can position more types of accessories. 
     In some embodiments, as shown in  FIG. 1 , a housing A 26  of the dust collection part A 2  includes: a vertical box A 261  and a horizontal seat A 262 . The vertical box A 261  is arranged vertically and having a front surface and two side surfaces. The front surface of the vertical box A 261  is wider than the side surface of the vertical box A 261 . The avoidance recess A 24  is formed in the front surface of the vertical box A 261 . The horizontal seat is horizontally coupled to a bottom of the vertical box A 261 . The vertical box body  261  is shaped to be generally flat relatively, and the arrangement of the horizontal seat A 262  is beneficial to increasing a contact area with the ground to improve the stability under the premise of ensuring the flatness of the upper part. 
     In one embodiment, a bottom surface of the avoidance recess A 24  is flush with an upper surface of the horizontal seat A 262 , or the bottom surface of the avoidance recess A 24  and the upper surface of the horizontal seat A 24  are connected in an arc transition. In this way, the inhalation attachment B 03  with a wide end can be fitted in the avoidance recess A 24  more conveniently and locked more easily. 
     In some embodiments, as shown in  FIGS. 3 and 4 , the dust inlet A 01  may include a first dust inlet A 011  and a second dust inlet A 012  that are arranged in parallel, that is, when the suction device A 3  is working, the first dust inlet A 011  and the second dust inlet A 012  can simultaneously suck dust from the cleaning apparatus B. The first dust inlet A 011  may be formed in the top surface of the first support sub-part A 102 , the second dust inlet A 012  may be formed in the top surface of the second support sub-part A 103 , and the support part A 1  is provided therein with a dust passage chamber in communication with the first dust inlet A 011 , the second dust inlet A 012  and the dust collection chamber A 22 . 
     Therefore, the dust collection part A 2  can suck the dust from the cleaning apparatus B through the first dust inlet A 011 , the second dust inlet A 012  and the dust passage chamber A 11  in the support part A 1 , so that the support part A 1  can be used for not only supporting the cleaning apparatus B, but also sucking dust. In this way, the structure of the dust accumulation base A becomes more compact. Moreover, since the support part A 1  has two dust inlets A 01 , the dust suction speed can also be increased and the waiting time of the user can be reduced. 
     In addition, it is worth noting that the number of dust passage chambers A 11  is not limited. For example, the dust passage chamber A 11  may be formed as an integral chamber coming into communication with the first dust inlet A 011  and the second dust inlet A 012  at the same time. For another example, there may be two dust passage chambers A 11  arranged in parallel, one of the dust passage chambers A 11  is arranged between and comes into communication with the first dust inlet A 011  and the dust collection chamber A 22 , and the other dust passage chamber A 11  is arranged between and comes into communication with the second dust inlet A 012  and the dust collection chamber A 22 . 
     In some embodiments, as shown in  FIGS. 3 and 4 , a dust passage chamber A 11  is defined in the dust accumulation base A and includes a gathering chamber A 112  and branch channels A 111 . One ends of the branch channels A 111  are respectively coupled to the dust inlets A 01 , and the other ends of the branch channels A 111  are both in communication with the gathering chamber A 112 . A bottom of the gathering chamber A 112  is provided with a dust collection opening A 122 . Here, the branch channel A 111  is correspondingly coupled to the dust inlet A 01  to guide the dust entering from the dust inlet A 01 . It should be noted here that one or more branch channels A 111  may be provided. In the case of one branch channel A 111 , it corresponds to a solution of one dust inlet A 01 . In the case of multiple branch channels A 111 , it corresponds to the solution of multiple dust inlets A 01 . Each branch channel A 111  corresponds to a dust inlet A 01 . 
     In some examples, two dust inlets A 01  are symmetrically arranged on the dust accumulation base A, and each dust inlet A 01  is respectively in communication with a branch channel A 111 , and the ends of the two branch channels A 111  are both in communication with the gathering chamber A 112 . 
     It can be seen from the above structure that the dust accumulation base A of the embodiment of the present application adopts a structure having multiple dust inlets A 01  and multiple branch channels A 111  which are in a one-to-one correspondence. When the cleaning apparatus B is coupled to the dust accumulation base A, the multiple dust outlets B 1211  on the cleaning apparatus B are butt-jointed to the dust inlets A 01  on the dust accumulation base A, and then the dust collected in the cleaning apparatus B can be discharged from the multiple dust inlets A 01  down to the dust accumulation base A. Based on the design of multiple dust inlets A 01 , in the case of multiple dust outlets B 1211  on the cleaning apparatus B, dust can be dumped from the multiple dust outlets B 1211  at the same time, not one by one. In this way, the dust dumping time can be shortened greatly, and the user can dump dust from the multiple dust outlets B 1211  at the same time, thus reducing the cleaning workload. 
     Due to adoption of a structure having one dust inlet A 01  and multiple branch channels A 111 , when the cleaning apparatus B is coupled to the dust accumulation base A, the multiple dust outlets B 1211  on the cleaning apparatus B are all butt-jointed to the dust inlets A 01  below. In this way, the structure of the dust inlet A 01  is simple, the design of the specific position of the dust outlet B 1211  on the cleaning apparatus B is less restricted, and thus the overall processing of the dust accumulation base A and the cleaning apparatus B is simple. 
     In addition, when the dust outlets B 1211  with multiple dust chamber separation chambers are formed in the cleaning apparatus, the dust outlet B 1211  that needs to be emptied can be selected according to the amount of dust collected in the dust chamber separation chambers, and accordingly the corresponding dust outlet B 1211  and dust inlet A 01  come into communication for targeted emptying. 
     In the present application, the dust entering from the dust inlet A 01  is gradually sent into the gathering chamber A 112  under the guidance of the branch channel A 111 ; that is, the dust dumped from the dust inlet A 01  is split and guided into the gathering chamber A 112 , and dust raising will not occur in this process. The dust in the multiple branch channels A 111  is gathered in the gathering chamber A 112  and is discharged from the dust collection opening A 122  to the subsequent components, thus achieving high dust accumulation efficiency. The dust collected at the dust collection opening A 122  can be introduced in a dust treatment component or dust collecting component for centralized treatment. 
     It can be understood that when multiple dust inlets A 01  and multiple branch channels A 111  are designed at the same time, the dust can be discharged and guided quickly, and dust raising will not occur. Compared a structure with the dust collection chamber but no branch channel, the structure of the present application has various forms and is more intensive and more compact. 
     In the following, the structure having multiple dust inlets A 01 , multiple dust outlets B 1211  multiple branch channels A 111  are described. 
     In some embodiments of the present application, as shown in  FIGS. 3 and 4 , in a direction from the dust inlet A 01  to the gathering chamber A 112 , the flow area of each branch channel A 111  gradually decreases. Therefore, the branch channel A 111  has a large dust feeding inlet but a small dust passage outlet. On the one hand, the cross-section of the branch channel A 111  gradually changes to form a funnel shape to facilitate diversion, the dust raising is reduced during the gradual accumulation of dust and dust collection is facilitated; on the other hand, due to this arrangement, the outline of the dust accumulation base at the corresponding branch channel A 111  gradually decreases in size, which is beneficial to reduction of the thickness of the whole machine. 
     As shown in  FIG. 4 , the gathering chamber A 112  is located below the dust inlet A 01 , and the horizontal projections of the dust inlet A 01  and the gathering chamber A 112  do not overlap. Each branch channel A 111  is a curved channel. Here, the dust entering from the dust inlet A 01  will not fall straight into the gathering chamber A 112 , but will pass through the middle curved branch channel A 111  curve to be cushioned and guided and then gathered into the gathering chamber A 112 , which can effectively reduce the upwelling of dust. In addition, the staggered arrangement between the dust inlet A 01  and the gathering chamber A 112  facilitates the arrangement of the support part A 1  (the structure of the support part A 1  is described later), so that the support part A 1  has more space arrangement possibilities when coupled to other components. 
     In one embodiment, the horizontal projections of the multiple dust inlets A 01  are arranged around the horizontal projection of the gathering chamber A 112 . When the dust inlets A 01  surround the gathering chamber A 112 , dust can quickly enter the gathering chamber A 112  from each dust inlet A 01 , and the branch channels A 111  are also easy to arrange, the branch channels A 111  can be easily formed as components with similar dimensions and similar connecting structures. The processing is easy, and the layout is more reasonable and more compact. 
     Advantageously, the horizontal projection of each dust inlet A 01  is evenly spaced around the center of the horizontal projection of the collection chamber A 112 , which facilitates the arrangement of the branch channel A 111  and realizes the quick dust guide. 
     In some embodiments, as shown in  FIGS. 3 and 4 , the supporting portion A 1  includes a support bottom shell A 12  and a support seat shell A 13 . 
     In one embodiment, as shown in  FIGS. 3 and 4 , the top of the support bottom shell A 12  is open to form a fitting opening A 121 , and a dust collection opening A 122  is formed at the bottom of the support bottom shell A 12 . It should be noted that  FIG. 4  does not show the opening (i.e., the fitting opening) at the top of the support bottom shell A 12  for the reason of the viewing angle; however, it should be understood that tops at the positions quoted by reference numerals A 121 , A 1211  and A 1212  in  FIG. 4  are open and correspond to the fitting opening, the central area and the branch area mentioned below, respectively. 
     The support seat shell A 13  is fitted on the fitting opening A 121 , and the dust inlet A 01  is formed on the support seat shell A 13 . By arranging the support part A 1  as two parts (i.e., the support bottom shell A 12  and the support seat shell A 13 ), the support seat shell A 13  is formed as a structure that is more conducive to supporting the cleaning apparatus B, so that the cleaning apparatus B can be connected conveniently; and the support bottom shell A 12  is formed as a structure for dust passage and dust collection, so that it is more easier to separately machine and manufacture various components of the support part A 1  according to their respective functional features. In one embodiment, the support bottom shell A 12  and the support seat shell A 13  are respectively integral injection molded parts, and the separate machining of the support bottom shell A 12  and the support seat shell A 13  is beneficial to mold release. 
     In one embodiment, as shown in  FIG. 3 , a dust passage chamber A 11  is defined between the support seat shell A 13  and the support bottom shell A 12 . When the support seat shell A 13  is butt-jointed to the support bottom shell A 12  through the fitting opening A 121 , a through dust passage chamber A 11  is formed. The dust inlet A 01  and the dust collection opening A 122  are respectively formed at two ends of the dust passage chamber A 11 . 
     In one embodiment, as shown in  FIG. 4 , the fitting opening A 121  includes a central area A 1211  and branch areas A 1212 , one ends of branch areas A 1212  respectively extend to the central area A 1211 , so that a contour line of the fitting opening A 121  is a single closed loop. As mentioned here that the contour line of the fitting opening A 121  is a single closed loop, it emphasizes that the central area A 1211  and branch areas A 1212  refer to different areas of the same opening. Dividing the fitting opening A 121  into a central area A 1211  and branch areas A 1212  is only for the convenience of describing the detailed structure of the support part A 1  later. The fitting opening A 121  is shaped like a flower, branch areas A 1212  are equivalent to petals. 
     When the support seat shell A 13  and the support bottom shell A 12  are butt-jointed through the fitting opening A 121 , the fitting opening A 121  is formed as a single closed loop so that the support bottom shell can be machined and formed easily. In addition, a certain guiding and positioning effect is achieved when the support bottom shell A 12  and the support seat shell A 13  are butt-jointed, so that the support seat shell A 13  keeps stable and does not wobble after being quickly installed on the support bottom shell A 12 . 
     Further, referring to  FIG. 4 , the dust collection opening A 122  is located below the central area A 1211 . The area of the dust collection opening A 122  is much smaller than that of the fitting opening A 121 , and it is mainly concentrated under the central area A 1211 . In this way, the curvature of the shell wall of the support bottom shell A 12  will not be too large, which is convenient for machining. 
     In one embodiment, the shape of the dust collection opening A 122  is consistent with the shape of the central area A 1211 ; for example, the central area A 1211  is square, the dust collection opening A 122  is square too. In some examples, the shape of the dust collection opening A 122  is not consistent with the shape of the central area A 1211 , for example, the central area A 1211  is square, but the dust collection opening A 122  is circular. 
     Advantageously, as shown in  FIG. 4 , the support bottom shell A 122  is shaped by gradually changing downward from a contour of the fitting opening A 121  to a contour of the dust collection opening A 122 . The support bottom shell A 12  is substantially formed into a shape with an upper top and a small bottom. On the one hand, the contour of the support bottom shell A 12  gradually changes downward to form a funnel shape to facilitate diversion, the dust raising is reduced during the gradual accumulation of dust and dust collection is facilitated; on the other hand, the outline of the support bottom shell A 12  gradually decreases in size and thus the support part A 1  is more intensive and more compact. 
     In one embodiment, as shown in  FIG. 4 , the contour shape of the support seat shell A 13  is consistent with the contour shape of the fitting opening A 121 , and the support seat shell A 13  is provided with a dust inlet A 01  corresponding to the branch area A 1212 . Based on the above structure, on the one hand, the positioning and assembly of the support seat shell A 13  and the support bottom shell A 12  are facilitated, and on the other hand, the fitting opening A 121  can be conveniently sealed completely, only the dust inlet A 01  is open to for suck dust. 
     After the support seat shell A 13  is coupled to the support bottom shell A 12 , they are in seamless connection and do not wobble, and moreover, the dust inlet A 01  is aligned with the branch area A 1212 ; the cleaning apparatus B is stably supported after being fitted on the support seat shell, and the effect of rapid dust discharge is also achieved. 
     In one embodiment, as shown in  FIG. 4 , the area on the support part A 1  between the two adjacent branch areas A 1212  and the central area A 1211  constitutes an avoidance area A 7 . The avoidance area A 7  is formed inside the support part A 1  to accommodate the suction accessory B 03  on the cleaning apparatus B, such as a push rod, a floor brush, or the like, so that the cleaning apparatus B can be directly placed on the support A 1  without detaching the accessory, which is convenient for operation and beneficial to use. 
     In the example of  FIGS. 3 and 4 , the dust inlet A 01  includes a first dust inlet A 011  and a second dust inlet A 012  that are arranged in parallel. The first dust inlet A 011  and the second dust inlet A 012  can simultaneously suck dust from the cleaning apparatus B. The first dust inlet A 011  and the second dust inlet A 012  are respectively formed on the top surface of the support seat shell A 13 , and the first dust inlet A 011  and the second dust inlet A 012  respectively come into communication with a branch area A 1212 . In this example, one avoidance area A 7  is provided, and the structure of the dust accumulation base A is compact and small structure and dust can be sucked in quickly. 
     Further, as shown in  FIG. 4 , a press block A 131  extending into the support bottom shell A 12  is formed at the bottom of the support seat shell. In the bottom surface of the press block A 131 , at least a portion of the bottom surface between the dust inlet A 01  and the central area A 1211  is formed as a curved guide surface A 1311  that gradually extends downward to the central area A 1211 . The curved guide surface A 1311  of the press block A 131  forms the top surface of the branch channel A 111 , which further improves the guiding effect of the branch channel A 111 . 
     In one embodiment, the support bottom shell A 12  is an integrally formed part, and the support seat shell A 13  is also an integrally formed part. A portion of the support seat shell A 13  is recessed downward to form the press block A 131 . The press block A 131  is added with a fitting surface between the support bottom shell A 12  and the support seat shell A 13 . Here, the support bottom shell A 12  and the support seat shell A 13  are respectively arranged as integral parts to facilitate the machining of the support bottom shell A 12  and the support seat shell A 13 , and the press block A 131  is formed by a portion of the support seat shell A 13  recessed downward. In this way, the weight of the support seat shell A 13  is reduced greatly. 
     In one embodiment, the support seat shell A 13  and the support bottom shell A 12  in the present application may also be of an integrally formed structure; that is, in the case of the above-mentioned contour shape, the dust inlet A 01  and the dust collection opening A 122 , the support seat shell A 13  and the support bottom shell A 12  are formed as an integrally formed structure, and a fitting opening A 121  is not required. 
     In some embodiments, as shown in  FIGS. 4 and 5 , the dust accumulation base A may further include an unlocking member A 5  configured to open a dust outlet lid B 122  on the cleaning apparatus B (in conjunction with  FIG. 6 ). Therefore, when the cleaning apparatus B is placed on the dust accumulation base A, the unlocking member A 5  on the dust accumulation base A can be configured to open the dust outlet lid B 122  on the cleaning apparatus B so that the dust inlet A 01  on the dust accumulation base A comes into butt-jointed connection with the dust outlet B 1211  on the cleaning apparatus B; in this way, the user does not need to manually operate the dust outlet lid B 122 , avoiding the user from getting his hands dirty and reducing the user&#39;s labor intensity. 
     In some embodiments, a closable dust outlet lid B 122  is arranged at each dust outlet B 1211 , each dust outlet B 1211  corresponds to a dust inlet A 01 , and the unlocking member A 5  is formed as push plates A 51  which are respectively arranged on edges of multiple dust inlets A 01 . The unlocking member A 5  has simple structure and is convenient to machine and manufacture, and push plates A 51  can also act on the cleaning apparatus B at the same time to open the multiple dust outlet lids B 122  (in conjunction with  FIG. 6 ) at the same time, improving the dust dumping efficiency. In one embodiment, the push plates A 51  are symmetrically arranged on the edges of the dust inlets A 01  to avoid interference of the push plates A 51  during work and facilitate machining. 
     As shown in  FIGS. 4 and 5 , the dust inlet A 01  includes a first dust inlet A 011  and a second dust inlet A 012  that are arranged in parallel. The unlocking member A 5  includes two push plates A 51  arranged axisymmetrically and arranged on an edge of the first dust inlet A 011  and an edge of the second dust inlet A 012 . Therefore, the unlocking member A 5  has simple structure and is convenient to machine and manufacture, and the two push plates A 51  can also act on the cleaning apparatus B at the same time to open the two dust outlet lids B 122  ((in conjunction with  FIG. 6 ), improving the dust dumping efficiency. In addition, by arranging the two push plates A 51  axisymmetrically, the actions of the two push plates A 51  can also be prevented from interfering with each other. 
     In some embodiments, as shown in  FIGS. 1 and 2 , the dust accumulation base A may include a guide member A 61  configured to guide the cleaning apparatus B. Therefore, the guide member A 61  can be configured to quickly align the cleaning apparatus B to the dust accumulation base A and assemble the cleaning apparatus B and the dust accumulation base A in place, improving the accuracy of the butting between the dust outlet B 1211  of the cleaning apparatus B and the dust inlet A 01  of the dust accumulation base A and ensuring smooth running of dust. 
     In some embodiments, as shown in  FIGS. 1 and 2 , the dust accumulation base A may include a positioning member A 62  configured to position the cleaning apparatus B. Therefore, the relative position between the cleaning apparatus B and the support part A 1  can be fixed by the positioning member A 62 , the user&#39;s hands can be released, and the user can leave the cleaning apparatus B alone on the dust accumulation base A, and then leave to do other things. 
     In some embodiments, a positioning member A 62  and a guide member A 61  are arranged on the dust accumulation base A at the same time. It is worth noting that the specific structural forms of the guide member A 61  and the positioning member A 62  are not limited, as long as the above functions can be realized. Moreover, the guide member A 61  and the positioning member A 62  can also be configured as a same component, and the component has both the positioning and guiding functions. For example, in the example shown in  FIGS. 1 and 2 , the dust accumulation base A has a special-shaped baffle A 611 . The shape of the special-shaped baffle A 611  matches the shape of the corresponding part on the cleaning apparatus B. When the cleaning apparatus B is placed on the dust accumulation base A, the special-shaped baffle A 611  can guide and position the cleaning apparatus B. 
     In one embodiment, as shown in  FIG. 9 , the top of the support part A 1  is provided with a special-shaped baffle A 611  for guiding and positioning the cleaning apparatus B, and the special-shaped baffle A 611  is provided corresponding to the avoidance area A 7 . The special-shaped baffle A 611  includes: two dust cup stoppers A 6111  which are respectively arranged along the contours of the two dust inlets A 01  on the sides away from each other; and an avoidance stopper A 6112  with two ends coupled to the two dust cup stoppers A 6111  and arranged along the contour of the avoidance area A 7 . The avoidance stopper A 6112  is coupled to one sides of the two dust cup stoppers A 6111  facing the central area A 1211 . Thus, the special-shaped baffle A 611  is formed as an integral part with both guiding and positioning functions. 
     In one embodiment, the present application is not limited to this. In other embodiments of the present application, the guide member A 61  and the positioning member A 62  may also be configured in other shapes, respectively. For example, the guide member A 61  may be configured as a guide post, and the positioning member A 62  may be configured as a positioning buckle, or the like, which will not be detailed here. 
     In some embodiments, the dust accumulation base A may include a seal member (not shown in the figure). The seal member is located at the edge of the dust inlet A 01  and configured to achieve sealing when the dust accumulation base A and the cleaning apparatus B are butt-jointed. Therefore, the seal member can be configured to ensure that the dust outlet B 1211  on the cleaning apparatus B and the dust inlet A 01  on the dust accumulation base A are tightly butt-jointed. On the one hand, the dust suction efficiency can be improved, and on the other hand, dust can be prevented from leaking out of a butt joint, thus avoiding secondary pollution to the environment. For example, in a example of the present application, as shown in  FIG. 5 , the top surface of the dust accumulation base A may have a sealing groove A 14  arranged around the dust inlet A 01 , and the seal member may be embedded in the sealing groove A 14 . When the cleaning apparatus B is supported on the edge of the dust inlet A 01 , the seal member and the cleaning apparatus B can form a seal around the dust inlet A 01 . 
     In one embodiment, the present application is not limited to this, and the dust inlet A 01  is not limited to being formed on the support part A 1 . For example, the dust inlet A 01  may also be arranged on the dust collection part A 2 . When located on the dust collection part A 2 , the dust inlet A 01  can be fixed on the dust collection part A 2 ; or a stretchable dust receiving cover can be arranged on the dust collection part A 2 . When the cleaning apparatus B is coupled to the support part are assembled in place, the dust receiving cover is pulled out to cover the dust outlet B 1211 . 
     In some embodiments, the dust accumulation base A may further include a first power port A 81 , and the first power port A 81  is adapted to being butt-jointed to the second power port B 23  on the cleaning apparatus B to charge the cleaning apparatus B. Therefore, when the cleaning apparatus B is placed on the dust accumulation base A, the dust accumulation base A can also be used to charge the cleaning apparatus B at the same time, thus achieving multiple functions; moreover, the user does not need to charge the cleaning apparatus B at other time, which facilitates the use. Moreover, the user places the cleaning apparatus B on the dust accumulation base A after use of the cleaning apparatus B, and during the period of time that the cleaning apparatus B is stored on the dust accumulation base A, the dust can be dumped out, the cleaning apparatus B can be charged and the user will not be worried about forgetting charging the cleaning apparatus B. 
     In some embodiments, as shown in  FIG. 6 , the air inlet pipe  01  of the cleaning apparatus B is provided with a second power port B 23 . When the cleaning apparatus B is fitted on the dust accumulation base A, the air inlet pipe  01  is located in the avoidance area A 7 . On the corresponding dust accumulation base A, as shown in  FIG. 9 , the first power port A 81  is located on the support part A 1  and in the avoidance area A 7 . In this case, the air inlet pipe  01  can be inserted into the avoidance area A 7  and the second power port B 23  is plugged into the first power port A 81  to complete the connection. In use of this dust accumulation base A, when other suction accessories B 03  are coupled to the air inlet pipe  01  on the cleaning apparatus B, the suction accessory B 03  coupled to the air inlet pipe  01  can be detached, and then the first power port A 81  can be connected. 
     In order to ensure that dust can also be dumped out of the cleaning apparatus B when the suction accessory B 03  coupled to the air inlet pipe  01  is not detached, in some examples, the first power port A 81  is arranged on a stretchable platform A 82 . As shown in  FIG. 9 , the stretchable platform A 82  is arranged on the support part A 1  in a horizontally stretching and retracting way. When the stretchable platform A 82  stretches out, the first power port A 81  extends into the avoidance area A 7 . In another example, the dust inlet A 01  is configured to be relatively large, and a certain redundant space is provided in the avoidance area A 7 . When the suction accessory B 03  coupled to the inlet pipe  01  is not detached, the cleaning apparatus B moves outward by a certain distance so that the suction accessory B 03  avoids the first power port A 81 . 
     It is understandable that the structural form of the first power port A 81  and the second power port B 23  capable of fulfilling the above charging function and a principle of implementing charging will not be detailed here. 
     In one embodiment, in embodiments of the present application, the position of the first power port A 81  is not limited to this. For example, a charging dock (not shown in the figure) connected by a wire is arranged on the dust collection part A 2 , and the first power port A 81  is arranged on the charging dock. 
     In some embodiments, as shown in  FIGS. 2 and 3 , the dust accumulation base A may further include a dust bag A 23  detachably arranged in the dust collection chamber A 22 . Therefore, the dust bag A 23  can be configured to collect the dust flowing to the dust collection chamber A 22 , which is convenient for the user to dump the dust and ensures the cleanness of the dust collection chamber A 22 . In addition, the dust bag A 23  is easy to disassemble, clean and replace, which is convenient for the user to operate and use. Here, it should be noted that a material of the dust bag A 23  is not limited; for example, the dust bag A 23  may be a paper bag, a mesh bag, a cloth bag or the like. In addition, the connection mode of the dust bag A 23  and the dust collection chamber A 22  is not limited as long as it is ensured that the dust bag A 23  can be disassembled and assembled conveniently. For example, the dust collection chamber A 22  may be provided therein with a movable buckle A 221 , the dust bag A 23  may be provided with a locking plate A 231 , and the locking plate A 231  can be positioned by the movable buckle A 221  so that an inlet of the dust bag A 23  comes into communication with an inlet of the dust collection chamber A 22 . 
     In addition, in some embodiments of the present application, as shown in  FIG. 2 , the dust collection part A 2  may further include a supporting frame A 28  arranged in the dust collection chamber A 22 , and the supporting frame A 28  is configured to support the dust bag A 23  to prevent the dust bag A 23  from blocking the air passage hole A 211 . In one embodiment, the present application is not limited to this. The dust collection chamber A 22  may not have a dust bag A 23  therein. In this case, the dust collection chamber A 22  may be provided therein with other filtering devices; for example, a filter screen is directly arranged at the air passage hole A 211  or the like to prevent dirt from entering the motor chamber A 21  to damage the suction device A 3 . 
     In some embodiments, as shown in  FIG. 3 , the dust collection part A 2  may also be provided therein with a storage chamber A 25 , and the storage chamber A 25  is not in communication with the motor chamber A 21  and the dust collection chamber A 22 . Thus, the storage chamber A 25  can be configured to store items, for example, to store accessories of the cleaning apparatus B, such as a floor brush, a pet brush, and the like, so that the dust accumulation base A has a storage function; therefore, the dust accumulation base A has powerful functions. It is worth noting that the location of the storage chamber A 25  in the dust collection part A 2  is not limited. For example, in the example shown in  FIG. 2 , the storage chamber A 25  can be arranged on a horizontal side of the dust collection chamber A 22  (e.g., the left side shown in  FIGS. 2 and 3 ), reducing the structural difficulty and facilitating machining and use. 
     In one embodiment, as shown in  FIGS. 3 and 1 , a storage chamber A 25  and a dust collection chamber A 22  are defined in the vertical box A 261 , and the storage chamber A 25  and the dust collection chamber A 22  are respectively arranged adjacent to two side surfaces of the vertical box A 261 . 
     As shown in  FIGS. 2 and 3 , both the storage chamber A 25  and the dust collection chamber A 22  can be configured as chambers that can be opened, so that the user can take and place the item or change the dust bag A 23  conveniently. For example, in a example of the present application, the dust collection part A 2  may include a housing A 26  and two cover plates A 27  arranged on the housing A 26 . One of the cover plates A 27  is configured to open and close the storage chamber A 25 , and the other cover plate A 27  is configured to open and close the dust collection chamber A 22 . The structural shape and layout position of the cover plate A 27  are not limited, and the connection mode of the cover plates A 27  and the housing A 26  is not limited as long as they can be disassembled and assembled conveniently. In addition, when the volume of the dust collection chamber A 22  needs to be increased, the storage chamber A 25  can also come into communication with the dust collection chamber A 22 , and the storage chamber A 25  and the dust collection chamber A 22  can both serve as the dust collection chamber A 22 . 
     In addition, the dust accumulation base A according to the embodiment of the present application may further include a switch A 29 . The switch A 29  may be arranged on the dust collection part A 2  or the support part A 1 , and after the switch A 29  is triggered, the suction device A 3  will start to work, bringing convenience for use and reducing the overall cost of the dust accumulation base A. In one embodiment, the present application is not limited to this, and the suction device A 3  can be automatically started to work according to an actual situation by remote control, voice control, gravity induction control, or the like, which will not be detailed here. 
     The cleaning apparatus assembly  1000  according to the embodiment of the second aspect of the present application will be described below with reference to the drawings. 
     As shown in  FIGS. 1 and 10 , the cleaning apparatus assembly  1000  according to the embodiment of the second aspect of the present application may include a dust accumulation base A and a cleaning apparatus B, and the dust accumulation base A is the dust accumulation base A according to the embodiment of the first aspect of the present application, and the cleaning apparatus B includes a dust cup component B 1 ; the dust accumulation base A is configured to support the cleaning apparatus B and suck dust from the dust cup component B 1 . It should be noted that the dust accumulation base A and the cleaning apparatus B can be separated, so the cleaning apparatus B is placed on the dust accumulation base A when the dust accumulation base A needs to be used, and the cleaning apparatus B is removed from the dust accumulation base A when the cleaning apparatus B needs to be used for cleaning operations. 
     Therefore, since the cleaning apparatus assembly  1000  according to the present application includes the dust accumulation base A, the dust accumulation base A can be used to hold the cleaning apparatus B, and the dust collection part A 2  can be used to collect the dust in the cleaning apparatus B, facilitating the dust dumping of the cleaning apparatus B and improving the dust dumping effect of the cleaning apparatus B. 
     It should be noted that the type of the cleaning apparatus B according to the embodiment of the present application is not limited, for example, it can be a hand-held vacuum cleaner, a hand-held push-rod vacuum cleaner, a mopping vacuum cleaner, or the like. After the type of cleaning apparatus B is determined, other components of the cleaning apparatus B. For example, when the cleaning apparatus B is a hand-held push-rod vacuum cleaner, the cleaning apparatus B may include a body component B 2 , a push rod (not shown), a floor brush (not shown), and the like in addition to the dust cup component B 1 . 
     In some embodiments, during the processing of dust dumping, a pressure difference is formed between the cleaning apparatus B and the dust collection chamber A 22  to generate airflow, bringing the dust into the dust collection chamber A 22 . 
     In some embodiments, as shown in  FIG. 7 , the cleaning apparatus B includes a body component B 2 , and the body component B 2  includes a motor assembly B 21 . The motor assembly B 21  has a suction fan wheel B 22  that can rotate forward to suck dust. The cleaning apparatus B can discharge dust by the suction fan wheel B 22  that rotates backward. It should be noted here that when the cleaning apparatus B is separated from the dust accumulation base A, the motor assembly B 21  in the cleaning apparatus B rotates forward to suck dust. When the motor assembly B 21  rotates forward, as shown in  FIG. 6 , the dust is sucked into the suction opening B 14  and enters the dust cup component B 1  in the cleaning apparatus B. When the cleaning apparatus B needs to empty the dust, the suction fan wheel B 22  rotates backward to discharge the dust. Alternatively, the dust accumulation base A has a suction device A 3 , and the suction device A 3  performs suction on the dust cup component B 1  to suck the dust. 
     In addition, the specific structure of the dust cup component B 1  is not limited as long as the dust and air separation can be achieved. For example, in a example of the present application, as shown in  FIGS. 6 and 7 , the dust cup component B 1  may be a cyclone separation type dust cup, and includes a primary separation chamber B 101  and a secondary separation chamber B 102 . The primary separation chamber B 101  is in airflow communication with the upstream of the secondary separation chamber B 102 . Dirty air sucked in by the dust cup component B 1  from the suction opening B 14  can first enter the primary separation chamber B 101  for preliminary cyclone separation two throw out large particles of dust and hair, and the preliminarily separated air can then enter the secondary separation chamber B 102  for another cyclone separation to throw out fine particles of dust, and then flow to the body component B 2 , improving the cleaning effect. 
     In one embodiment, as shown in  FIG. 6 , a filter element B 13  is provided in the primary separation chamber B 101  to increase the preliminary separation effect of dust and airflow. 
     In addition, when the primary separation chamber B 101  and the secondary separation chamber B 102  are arranged in sequence in a horizontal direction and are each provided with a dust outlet B 1211  at the bottom, the first dust inlet A 011  and the second dust inlet A 012  can be respectively coupled to the two dust outlets B 1211  correspondingly so that the first dust inlet A 011  can collect the dust stored in the primary separation chamber B 101  and the second dust inlet A 012  can collect the dust stored in the secondary separation chamber B 102 . 
     In some embodiments, as shown in  FIGS. 6 and 7 , the dust cup component B 1  may include a cup body B 11  and a cup lid sub-component B 12 . A cup lid body B 121  may be arranged on the cup body B 11  and able to open and close, and the cup lid body B 121  may also be fixed on the cup body B 11 . The cup lid sub-component B 12  includes a cup lid body B 121  and a dust outlet lid B 122 . The cup lid body B 121  is provided with the dust outlet B 1211 . The dust outlet lid B 122  is arranged on the cup lid body B 121  and configured to open and close the dust outlet B 1211 . When the cleaning apparatus B and the dust accumulation base A are fitted in place, the dust outlet B 1211  and the dust inlet A 01  are opposite to each other. 
     Therefore, by placing the cleaning apparatus B on the dust accumulation base A and opening the dust outlet lid B 122 , the dust outlet B 1211  and the dust inlet A 01  can come into butt-jointed communication so that the dust accumulation base A can collect dust from the dust cup component B 1 . Because the dust outlet B 1211  and the dust inlet A 01  can come into butt-jointed communication, the leakage and raising of dust in the dust dumping process can be avoided, and secondary pollution to the environment can also be avoided. In addition, when the cup lid body B 121  is coupled to the cup body B 11  and can be opened and closed, the dust can also be manually dumped into an indoor trash can by opening the cup lid body B 121 , which is flexible in use. 
     In some embodiments, the structure of the cup lid body B 121  is eliminated in the cup lid sub-component B 12 , the dust outlet lid B 122  is provided at one end of the dust cup component B 1 , and the dust outlet lid B 122  is arranged on the cup body B 11  to open and close the dust outlet B 1211 , and a locking mechanism B 123  can directly lock the dust outlet lid B 122  on the cup body B 11 . 
     In some embodiments, as shown in  FIG. 8 , the cup lid sub-component B 12  may include the locking mechanism B 123 . The locking mechanism B 123  is arranged between the dust outlet lid B 122  and the cup lid body B 121  and configured to drive the dust outlet lid B 122  to close the dust outlet B 1211 . In this way, the dust outlet B 1211  can be closed by the locking mechanism B 123 , and the user does not need to manually close the dust outlet lid B 122 , preventing the user&#39;s hands from getting dirty. 
     In some embodiments, the cleaning apparatus assembly  1000  may include an unlocking device C arranged on at least one of the dust cup component B 1  and the dust accumulation base A; that is, the dust cup component B 1  may be provided with the unlocking device C (this example is not shown in the figure), and the dust accumulation base A may also be provided the unlocking device C (as shown in  FIG. 2 ). The dust cup component B 1  and the dust accumulation base A may be each provided with the unlocking device C. The unlocking device C is configured to drive the locking mechanism B 123  to unlock and drive the dust outlet lid B 122  to open the dust outlet B 1211 . 
     In other words, the unlocking device C may be arranged on the cleaning apparatus B. For example, the unlocking device C may be configured as an unlocking switch; when touched by a human hand, the unlocking switch is triggered and the locking mechanism B 123  is driven to unlock. The unlocking device C can also be arranged on the dust accumulation base A. When the cleaning apparatus B is coupled to the dust accumulation base A, the unlocking device C comes into contact with the locking mechanism B 123 , the locking mechanism B 123  is triggered to unlock, and the dust outlet lid B 122  opens the dust outlet B 1211 . It can be seen from the above structure that the dust outlet lid B 122  arranged on the dust outlet B 1211  of the cleaning apparatus B according to the embodiment of the present application is generally in a closed state under the action of the locking mechanism B 123 . Therefore, the dust outlet lid B 122  always closes the dust outlet B 1211  and the cleaning apparatus B can be conveniently used to clean dust and at the same time the dust is gradually accumulated in the dust cup component B 1 . 
     Since the cup body B 11  has a certain dust holding capacity, when the dust is accumulated to a certain amount and the cleaning apparatus B needs to be emptied, the unlocking device C triggers the locking mechanism B 123  and the locking mechanism B 123  is then driven; as a result, the locking effect of the locking mechanism B 123  on the dust outlet lid B 122  is removed and the dust outlet lid B 122  is opened immediately, and then the dust can be dumped out from the dust outlet B 1211 . In summary, since the cleaning apparatus B of the present application has an automatically openable dust outlet lid B 122  structure, dust can be dumped conveniently and hands will not get dirty when dumping dust, reducing labor intensity when dumping dust. 
     Therefore, since the unlocking device C can be configured to drive the dust outlet lid B 122  to open the dust outlet B 1211 , the user does not need to manually open the dust outlet lid B 122 , thus preventing the user&#39;s hands from getting dirty. 
     In one embodiment, the specific structures of the locking mechanism B 123  and the unlocking device C are not limited as long as they can achieve the above-mentioned functions. A example will be briefly described below as an example, but the present application is not limited to this. 
     In some embodiments, as shown in  FIG. 8 , the locking mechanism B 123  includes a slider B 1231 , a first return member B 1232 , and a second return member B 1233 . The first return member B 1232  normally drives the dust outlet lid B 122  to move in a direction of closing the dust outlet B 1211 , and the second return member B 1233  normally drives the slider B 1231  to stop the dust outlet lid B 122  from moving in a direction of opening the dust outlet B 1211 . That is, the first return member B 1232  effectively realizes the automatic closing of the dust outlet lid B 122 , and the second return member B 1233  and the slider B 1231  are used to lock the dust outlet lid B 122  to avoid automatically opening the dust outlet B 1211 ; in this way, the reliability and airtightness of dust storage of the dust cup component B 1  can be improved and the cleaning apparatus B can be ensured to operate normally. 
     Here, the materials of the first return member B 1232  and the second return member B 1233  are not limited as long as they can achieve the above functions. For example, the first return member B 1232  and the second return member B 1233  can be springs, torsion springs, gear rack components, magnetic attraction parts, or the like. 
     In addition, the structure of the slider B 1231  is not limited as long as the structure can achieve the above functions; for example, the slider B 1231  can be configured as a slider with a guide rail or a slider with a guide surface. 
     In some embodiments, as shown in  FIGS. 6 and 8 , the dust outlet lid B 122  is rotatably coupled to the cup body B 11 , that is, the dust outlet lid B 122  is rotatable about the rotation axis relative to the cup body B 11 . In this case, the dust outlet lid B 122  can move by way of rotating. 
     In one embodiment, the dust outlet lid B 122  and the cup body B 11  are connected in translation, that is, the dust outlet lid B 122  moves parallel to the cup body B 11 . The specific connection structure of the dust outlet lid B 122  and the cup body B 11  is not limited, as long as it can achieve rotation or translation. A specific example where the dust outlet lid B 122  and the cup body B 11  are in rotating connection is described below to illustrate the fitting form of the dust outlet lid B 122  and the locking mechanism B 123 . 
     In some examples, the dust outlet lid B 122  is rotatably coupled to the cup lid body B 121 , the first return member B 1232  normally drives the dust outlet lid B 122  to turn over and close the dust outlet lid B 1211 , the slider B 1231  is adjacent to a side of a rotation shaft of the dust outlet lid B 122 , and the second return member B 1233  is coupled to one end of the slider B 1231  and normally drives the slider B 1231  to abut against a side of the dust outlet lid B 122  facing the inside of the cup body B 11 . 
     In one embodiment, a guide surface is formed on the slider B 1231  and the unlocking device C extends along the guide surface into a space between the slider B 1231  and the dust outlet lid B 122  so that the slider B 1231  is separated from the dust outlet lid B 122  and then the dust outlet lid B 122  is unlocked to open the dust outlet B 1211 . Advantageously, as shown in  FIG. 8 , the guide surface is formed as an inclined guide surface B 12310  which extends downward in the direction away from the dust outlet B 1211 ; that is, an end of the inclined guide surface B 12310  close to the dust outlet B 1211  is higher and an end of the inclined guide surface B 12310  far from the dust outlet B 1211  is lower; and the end close to the dust outlet B 1211  is more easily fitted on the dust outlet lid B 122  to achieve locking. 
     Specifically, as shown in  FIG. 8 , the first return member B 1232  is configured as a torsion spring wound on the rotation shaft of the dust outlet lid B 122 . When the dust outlet lid B 122  is closed on the dust outlet B 1211 , the torsion spring accumulates energy. The second return member B 1233  is a coil spring fitted over one end of the slider B 1231 . The slider B 1231  is configured as a wedge block and has an inclined guide surface B 12310 . When the inclined guide surface B 12310  is pushed upward by the unlocking device C, the slider B 1231  moves horizontally and the coil spring is compressed to accumulate energy, to release and unlocking the dust outlet lid B 122  to form an automatic opening structure. When the acting force of the unlocking device C is removed, the slider B 1231  moves toward the dust outlet B 1211  under the action of the coil spring, the dust outlet lid B 122  closes the dust outlet B 1211  under the action of the torsion spring, and in the meanwhile one end of the dust outlet lid B 122  abuts against the slider B 1231  to achieve locking. 
     In some examples, the dust outlet lid B 122  and the cup body B 11  are connected in translation. Correspondingly, in this case, a via hole is formed in the convex ring B 1214  so that the dust outlet lid B 122  can be moved to the side of the dust outlet B 1211  or to the space between the dust outlet lids B 1211  through the via hole, and the first return member B 1232  and the second return member B 1233  are formed as a set of parts, specifically as a magnetic member arranged at one end of the dust outlet lid B 122  and a magnetic attraction member fitted on the dust outlet B 1211 . By virtue of a magnetic attraction force, the magnetic member and the magnetic attraction member can drive the dust outlet lid B 122  to normally move in a direction of closing the dust outlet B 1211 ; the second return member B 1233  is configured as a tension spring provided at the other end of the dust outlet lid B 122 , and when the dust outlet lid B 122  closes the dust outlet B 1211 , the tension spring is in a tensioned state. The magnetic attraction force is greater than the elastic restoring force of the tension spring. That is, without the unlocking device C providing an external force to overcome the difference in the force between the magnetic attraction force and the elastic restoring force of the tension spring, the dust outlet lid B 122  normally closes the dust outlet B 1211 . 
     In one embodiment, the unlocking device C may include a motor, a damping gear, and a damping rack, and the damping gear is arranged on the dust outlet lid B 122 , the damping rack is arranged on the cup cover body B 121 , and a motor drives the damping gear to move relative to the damping rack. When the motor is turned on, the damping gear drives the dust outlet lid B 122  to move along a path of the damping rack, so that the dust outlet lid B 122  overcomes the magnetic attraction force of the magnetic member and the magnetic attraction member, and moves in a direction of opening the dust outlet B 1211  under the action of the tension spring. 
     In the example shown in  FIG. 2 , the unlocking device C may include an unlocking member A 5  arranged on the dust accumulation base A. When the cleaning apparatus B and the dust accumulation base A are fitted in place, the unlocking member A 5  pushes the dust outlet lid B 122  to turn over in the direction of opening the dust outlet B 1211  and pushes the slider B 1231  to slide in a direction of releasing the dust outlet lid B 122 . Therefore, by placing the cleaning apparatus B on the dust accumulation base A, the unlocking member A 5  can automatically open the dust outlet lid B 122  to realize the communication between the dust outlet B 1211  and the dust inlet A 01 , without manual operation by the user, thus reducing the operating intensity and preventing the hands from getting dirty; after removing the cleaning apparatus B from the dust accumulation base A, the first return member B 1232  can be used to simply and effectively realize the automatic closing of the dust outlet lid B 122 , and the second return member B 1233  and the slider B 1231  are used to lock the dust outlet lid B 122  to avoid automatically opening the dust outlet B 1211 ; in this way, the reliability and airtightness of dust storage of the dust cup component B 1  can be improved and the cleaning apparatus B can be ensured to operate normally. In short, by providing the locking mechanism B 123  and the unlocking device C of this embodiment, the dust outlet lid B 122  can be automatically opened or closed. 
     In one embodiment, the unlocking member  5  includes a push plate A 51  which is arranged adjacent to the dust inlet A 01 . When the dust outlet B 1211  is butt-jointed toward the dust inlet A 01 , the push plate A 51  pushes the dust outlet lid B 122  to open the dust outlet B 1211 . In some specific examples, the push plate A 51  can provide an upward pushing force, and the unlocking device C cooperates with the aforementioned case where the dust outlet lid B 122  is rotatably coupled to the cup lid body B 121 . Advantageously, the push plates A 51  are symmetrically arranged on the edges of the dust inlets A 01  to avoid interference of the push plates A 51  during work and facilitate machining. 
     In the specific example shown in  FIG. 8 , the cup lid body B 121  has two dust outlets B 1211 , the dust cup component B 1  includes two dust outlet lids B 122 , and the two dust outlet lids B 122  are respectively used to open and close the two dust outlets B 1211  correspondingly. The two dust outlet lids B 122  are mirrored left and right, and two sliders B 1231  that are mirrored left and right are arranged between the two dust outlet lids B 122 . Therefore, when the dust outlet lids B 122  on the left and right sides adopt the same and mirrored locking mechanism B 123  and unlocking device C, the dust outlet lids B 122  on the left and right sides can be opened synchronously in the same way, and the dust outlet lids B 122  can also be closed synchronously in the same way. Therefore, in order to simplify the description, only the dust outlet lid B 122  on the left side is described as an example. 
     In the example of the dust outlet lid B 122  on the left side, a right end of the slider B 1231  is provided with a second return member B 1233  (e.g., a return spring), the return spring pushes the slider B 1231  to normally be at a left limit position to push against a right end of the dust outlet lid B 122  on the left side so that the dust outlet lid B 122  is in the close position. In this case, the first return member B 1232  (e.g., a torsion spring) on the rotation shaft of the dust outlet lid B 122  is in a natural state. When the cleaning apparatus B is placed on the dust accumulation base A, the push plate A 51  on the left side as shown in  FIG. 5  pushes upward the dust outlet lid B 122  on the left side so that the dust outlet lid B 122  turns over in a counterclockwise direction as shown in  FIG. 8  to compress the torsion spring on the rotation shaft of the dust outlet lid B 122  on the left side; in the meanwhile, the right end of the dust outlet lid B 122  applies an upward pushing force to the inclined guide surface B 12310  so that the left slider B 1231  moves to the right to compress the return spring on the right side of the left slider B 1231 , thus reaching an unlocked state. 
     When the cleaning apparatus B is removed from the dust accumulation base A, as shown in  FIG. 5 , the push plate A 51  on the left side is withdrawn downward relative to the dust outlet lid B 122 , and the torsion spring on the rotation shaft of the dust outlet lid B 122  on the left side pushes the dust outlet lid B 122  to turn over in the clockwise direction as shown in  FIG. 8 ; in the meanwhile, the return spring on the right side of the left slider B 1231  pushes the left slider B 1231  to move to the left to push against the upper right end of the dust outlet lid B 122  on the left side so that the dust outlet lid B 122  is locked in the close position. 
     In some embodiments of the present application, the cup lid body B 121  includes an inner lid B 1212  and an outer lid B 1213 , the inner lid B 1212  is fitted on the cup body B 11 , and the inner lid B 1212  is provided with a dust outlet B 1211 . The outer lid B 1213  is arranged on a side of the inner lid B 1212  away from the cup body B 11 , and the locking mechanism B 123  is arranged between the inner lid B 1212  and the outer lid B 1213 . When two layers of lids are provided, a certain accommodating space is formed between the lids to arrange the locking mechanism B 123 , so that the arrangement position of the locking mechanism B 123  is relatively concealed without being exposed, the locking mechanism B 123  is prevented from the interference of dust when the dust is dumped, the operating reliability of various components is maintained. In this way, the dust outlet lid B 122  can be locked by the locking mechanism B 123  and remains closed continuously during the process of emptying dust from the cleaning apparatus B. 
     In one embodiment, as shown in  FIGS. 7 and 8 , the inner lid B 1212  is provided with a convex ring B 1214  surrounding the dust outlet B 1211 , and the dust outlet lid B 122  is fitted on the convex ring B 1214 . Due to the arrangement of the convex ring B 1214 , when the dust outlet lid B 122  opens the dust outlet B 1211 , on the one hand, it is conducive to the dust accumulated in the dust cup component B 1  to fall along an inner wall of the convex ring B 1214 , forming a certain guiding effect; on the one hand, the convex ring B 1214  cooperates with the dust outlet lid B 122  to better seal the dust outlet B 1211 , so the size of the dust outlet lid B 122  does not need to be too large. Multiple dust outlets B 1211  and multiple dust outlet lids B 122  may be designed, which is beneficial to reducing the weight of the single dust outlet lid B 122 . In this way, the locking force required by the locking mechanism B 123  when locking the single dust outlet lid B 122  does not need to be too large, which is beneficial to the simplified design of the locking mechanism B 123 . 
     In addition, the convex ring B 1214  can be designed into a downwardly protruding structure. In this way, the convex rings B 1214  are formed between the inner lid B 1212  and the outer lid B 1213 ; convex rings B 1214  separate multiple spaces, and part of the spaces can be used for installing the locking mechanism B 123 , thus providing a reasonable layout space for the arrangement of the locking mechanism B 123 . 
     Advantageously, the convex ring B 1214  is formed as a ring structure extending from the inner lid B 1212  to the outer lid B 1213 , and two ends of the convex ring B 1214  are respectively coupled to the inner lid B 1212  and the outer lid B 1213 ; in this way, a relatively closed dust outlet channel is formed so that the dust can be dumped smoothly without getting jammed. Correspondingly, a dust passage outlet corresponding to the dust outlet B 1211  is also designed on the outer lid B 1213 , so that the dust can be quickly discharged. 
     In one embodiment, the dust outlet lid B 122  is provided with a groove that matches with the convex ring B 1214 . When the dust outlet lid B 122  is closed on the convex ring B 1214 , a better sealing effect is achieved between the dust outlet B 1211  and the dust outlet lid B 122  and the dust hardly leaks out. 
     In the figure, the cup lid body B 121  is provided with two dust outlets B 1211  and two corresponding dust outlet lids B 122 . Two locking mechanisms B 123  are provided correspondingly and arranged between the two dust outlets B 1211 . In one embodiment, in other examples, the number of dust outlets B 1211  may not be limited to two, but may be three or more, which is not limited specifically here. Advantageously, the dust outlets B 1211  are spaced apart and evenly arranged relative to a point, so that projections of dust outlets B 1211  in the horizontal direction cover horizontal projections of the separation chambers as much as possible to form rapid dust discharge. 
     On the cleaning apparatus B, a main body B 0  of the cleaning apparatus B serves as the most basic structure for the operation of the cleaning apparatus B, and other structures may not be provided or may be provided and coupled to the main body B 0 . The main body B 0  includes a dust cup component B 1  and a body component B 2 . The cleaning apparatus B further includes other accessories detachably coupled to the main body B 0 . 
     In some embodiments, with reference to  FIGS. 11 to 13 , the main body B 0  has a main suction channel B 011  for air suction to the dust cup component B 1  and an air outlet B 02  for discharging air. The cleaning apparatus B further includes a closing component B 3  that closes the main suction channel B 011  when triggered. It should be noted here that when the cleaning apparatus B works for cleaning normally, the dust outlets B 1211  are closed. Dust-containing air is sucked in from the main suction channel B 011 , and airflow in the dust cup component B 1  rotates at a high speed. The dust in the airflow is separated from the airflow by a centrifugal force, and then the airflow in the dust cup component B 1  is discharged toward the air outlet B 02 . The airflow discharged from the dust cup component B 1  can be directly discharged from the air outlet B 02 , or the airflow can also pass through other dust removal processes such as a filter (such as hepa or filter cotton) before the air is discharged, which is not limited here. 
     If dust needs to be discharged out of a conventional cleaning apparatus, a usual method is to open the dust outlet lid and put the dust outlet downwards so that the dust is discharged freely by gravity. In this way, it is difficult to discharge dust at corners in the dust cup component and the dust is always attracted to the inner wall of the dust cup component under the action of static electricity and the like. 
     In the embodiment of the present application, by providing the closing component B 3 , the cleaning apparatus B can realize a brand-new dust discharging method. Specifically, in the process of discharging dust out of the cleaning apparatus B, the main suction channel B 011  can be closed by the closing component B 3 , air is sucked in from the air outlet B 02 , and the air discharges sundries out of the main body B 0  from the dust outlet B 1211 . Here, the airflow can discharge the dust from the dust outlet B 1211  by way of blowing air toward the dust cup component B 1  so that the dust cup component B 1  forms a positive pressure relative to the outside atmosphere. In this way, the dust attached to the inner wall can be blown out more easily under a certain pressure difference, improving the cleanliness and efficiency of dust discharging. The airflow can also discharge the dust by way of sucking air into the dust cup component B 1  so that the dust cup component B 1  forms a negative pressure relative to the outside atmosphere. In this way, the dust attached to the inner wall can be removed more easily under a certain pressure difference, improving the cleanliness and efficiency of dust discharging. 
     What needs to be added here is that if the air outlet B 02  is closed by the closing component B 3 , the air flows in from the main suction channel B 011  and then is discharged from the dust outlet B 1211 . In this way, since wind resistance from the main suction channel B 011  to the dust outlet B 1211  is too small, it is always difficult to maintain a certain positive or negative pressure in the dust cup component B 1 , and in the main body B 0 , due to the easy pressure relief, the pressure difference cannot be used to cause dust to be removed from the inner wall. In the embodiment of the present application, since the air is sucked in from the air outlet B 02 , it is easier to form a certain pressure difference between the inside of the main body B 0  and the outside atmosphere, so that the dust can be dumped more thoroughly. 
     In addition, sucking the air in from the air outlet B 02  can also bring the dust between the dust cup component B 1  and the air outlet B 02  to the dust outlet B 1211 , further improving the cleanliness of the cleaning apparatus B. For example, when a filter is provided between the dust cup component B 1  and the air outlet B 02 , the dust will be blocked by a windward side of the filter when the cleaning apparatus B works normally for cleaning, and in the case of dust dumping, the air is sucked in from the opposite direction, the dust on the windward side will be brought by the airflow to the dust outlet B 1211 , that is, the dust dumping operation also can clean the filter. 
     It is understandable that, compared with a cleaning apparatus using manual dust discharging in the prior art, the cleaning apparatus B of the present application can discharge the dust quickly without causing raised dust or dirtying the hands. Compared with the prior art using a fluid (water or high-pressure airflow) to wash the dust in the apparatus, the cleaning apparatus B of the present application has a simple structure and a good dust discharging effect since no booster device is designed therein. 
     In some embodiments of the present application, as shown in  FIG. 13 , the dust cup component B 1  has a dust cup inlet B 111 ; the main body B 0  includes an air inlet pipe B 11 , one end of the air inlet pipe B 01  is configured as a connection opening B 012  coupled to the dust cup inlet B 111 , and the main suction channel B 011  is defined in the air inlet pipe B 01 . The closing component B 3  extends into a space between the connection opening B 012  and the dust cup inlet B 111  when triggered. Here, it should be noted that the air inlet pipe B 01  and an outer wall of the dust cup component B 1  may be configured as two parts, and the dust cup inlet B 111  and the connection opening B 012  are configured as two independent openings; the air inlet pipe B 01  may also be integrally formed one the outer wall of the dust cup component B 1 , and in this case the dust cup inlet B 111  and the connection opening B 012  are the same opening. 
     When the air inlet pipe B 01  and the outer wall of the dust cup component B 1  are configured as two independent parts, other connecting parts (such as a first seal member B 4  and the second seal member B 5  described later) can be arranged between the air inlet pipe B 01  and the outer wall of the dust cup component B 1 , No matter how the structures of the dust cup inlet B 111  and the connection opening B 012  are designed, a certain space needs to be formed between the air inlet pipe B 01  and the outer wall of the dust cup component B 1 , so that the closing component B 3  extends in the space and the chamber in the dust cup component B 1  and the air inlet pipe B 01  do not come into communication with each other. In the following, the structure where the dust cup inlet B 111  and the connection opening B 012  are designed as two opening is used to describe the manner in which the closing component B 3  of the embodiment of the present application closes the main suction channel B 011 . 
     As shown in  FIGS. 12 and 13 , the main body B 0  further includes a first seal member B 4  and a second seal member B 5 . The first seal member B 4  is arranged around the dust cup inlet B 111 , and the second seal member B 5  is arranged around the connection opening B 012 . The closing component B 3  extends a space between the first seal member B 4  and the second seal member B 5  when triggered. On the one hand, the first seal member B 4  and the second seal member B 5  can surround the dust cup inlet B 111  and the connection opening B 012  respectively and ensure better sealing performance after the two openings are connected, which facilitates dust suction from the air inlet pipe B 01  when the cleaning apparatus B works for sucking dust. On the other hand, the first seal member B 4  and the second seal member B 5  can also take a certain guiding effect at the junction. When moving from the outside to a gap between the first seal member B 4  and the second seal member B 5 , the closing component B 3  can push and open joint edges of the first seal member B 4  and the second seal member B 5  and extend into the gap between the first seal member B 4  and the second seal member B 5 , and finally close the main suction channel B 011 . In addition, the first seal member B 4  and the second seal member B 5  also protect the walls of the dust cup inlet B 111  and the connection opening B 012  from being worn by the closing component B 3 , and improve the effectiveness and durability of the closing component B 3  in blocking the main suction channel B 011 . 
     In one embodiment, in some embodiments, the main body B 0  does not need to be provided with the first seal member B 4  and the second seal member B 5 . In this case, only a channel that can be opened and closed and fits with the closing component B 3  needs to be formed in the air inlet pipe B 01  and close to the connection opening B 012 . When the cleaning apparatus works for cleaning, the channel that can be opened and closed is closed. When dust needs to be discharged, the channel that can be opened and closed is opened, and then the closing component B 3  extends into the air inlet pipe B 01  from the channel that can be opened and closed. 
     In some other embodiments, a portion of the closing component B 3  constitutes a portion of the channel that can be opened and closed when the channel is closed, and the closing component B 3  can slide or rotate relative to the channel that can be opened and closed. When the cleaning apparatus works for cleaning, the end of the closing component B 3  closes the channel that can be opened and closed. When dust needs to be discharged, the closing component B 3  slides or rotates toward the air inlet pipe B 01  and cuts off the air inlet pipe B 01 , sealing the chambers on two sides. 
     In some embodiments, the closing component B 3  is arranged on the main body B 0 . It occupies less external space, will not get lost easily, and facilitates the design of an automatic air path closing structure. 
     In some embodiments, referring again to  FIGS. 11 and 12 , the closing component B 3  includes: a closing door B 31 , a normally open return member B 32 , and an adjusting member B 33 . 
     The closing door B 31  has a close position for closing the main suction channel B 011  and an open position for opening the main suction channel B 011 . In the example, as disclosed above, where the closing component B 3  extends into the space between the connection opening B 012  and the dust cup inlet B 111  when triggered, in the close position, the closing door B 31  extends into the above-mentioned space between the connection opening B 012  and the dust cup inlet B 111  to close the main suction channel B 011 , and in the open position, the closing door B 31  exits from the main suction channel B 011 , so that the main suction channel B 011  comes into communication with the dust cup component B 1 . 
     Advantageously, the closing door B 31  is formed into a shape that fits with a cavity section of the main suction channel B 011 , so that the closing door B 31  can close the main suction channel B 011  as much as possible after extending into the main suction channel B 011 . 
     The normally open return member B 32  in the closing component B 3  normally drives the closing door B 31  to move toward the open position. That is, when the closing door B 31  is in the close position, the closing component B 3  normally drives the closing door B 31  so that the closing door B 31  has a tendency to move toward the open position. 
     In one embodiment, the normally open return member B 32  is configured as a spring. When the closing door B 31  is in the close position, the spring accumulates energy. When the closing component B 3  loses an external triggering force, the spring releases the energy so that the closing door B 31  exits from the main suction channel B 011  until the closing door B 31  moves to the open position. 
     In one embodiment, one end of the spring is coupled to the closing door B 31 , and the other end of the spring is coupled to the outer wall of the air inlet pipe B 01 . 
     In addition, the adjusting member B 33  in the closing component B 3  is coupled to the closing door B 31  and drives the closing door B 31  to move when triggered. The adjusting member B 33  gives the closing component B 3  an action point that is triggered by an external force, so that the closing component B 3  is quickly triggered to close the main suction channel B 011  when triggered. 
     In the embodiment of the present application, the adjusting member B 33  has many structural forms. For example, the adjusting member B 33  is located outside the main body B 0 . When the adjusting member B 33  is manually moved, the elastic force of the normally open return member B 32  can be overcome to drive the closing door B 31  to take a closing action. For another example, the adjusting member B 33  is configured as an electronically controlled actuating member (such as a solenoid valve). The adjusting member B 33  can act after receiving an electric control signal of closing, and overcome the elastic force of the normally open return member B 32  to drive the closing door B 31  to take a closing action; after receiving an electric control signal of opening, the adjusting member B 33  can act again to leave the closing door B 31 , and the closing door B 31  will take an opening action under the elastic force of the normally open return member B 32 . 
     In some examples, as shown in  FIG. 12 , the closing component B 3  further includes: a guide sheet B 34 . The guide sheet B 34  is annular or semi-annular and is fitted over the main suction channel B 011 , specifically fitted over the outer wall of the air inlet pipe B 01 . The closing door B 31  is coupled to the guide sheet B 34 . The guide sheet B 34  increases the movement stability of the closing component B 3  when the closing component B 3  is triggered, so that the closing door B 31  opens and closes the main suction channel B 011  in a specific direction. 
     In one embodiment, the adjusting member B 33  is coupled to the outside of the guide sheet B 34 . Further, in one embodiment, the adjusting member B 33  is arranged on a peripheral surface of the guide sheet B 34  and extends out from the inside of the main body B 0 . When the adjusting member B 33  is triggered to slide, the adjusting member B 33  drives the guide sheet B 34 , and the guide sheet B 34  drives the closing door B 31  to slide. In this way, since the closing door B 31  is driven by the guide sheet B 34 , the stability of the closing door B 31  taking opening and closing actions is further improved by the guiding effect of the guide sheet B 34 . 
     In one embodiment, referring again to  FIG. 11 , the main body B 0  further includes a protective shell B 6  covering an outer side of the main suction channel B 011 , an accommodation chamber is defined between the protective shell B 6  and the outer wall of the main suction channel B 011 , and the closing component B 3  is located in the accommodation chamber. The protective shell B 6  can cover a portion of the structure of the air inlet pipe B 01  and can also cover a joint structure between the dust cup component B 1  and the air inlet pipe B 01  so that the main body B 0  has a good integrity and a neater appearance. In addition, since the closing component B 3  is arranged in the accommodation chamber, various components of the closing component B 3  can be protected, and it is ensured that the closing component B 3  is not affected by the external environment when taking an action. 
     In one embodiment, the protective shell B 6  is formed as a multi-piece sub-shell. At least a portion of the multi-piece sub-shell is coupled to the air inlet pipe B 01  and the main body B 0 , so that the protective shell B 6  is stably coupled to the main body B 0  and the air inlet pipe B 01 . 
     Advantageously, as shown in  FIGS. 11 and 12 , a sliding groove B 61  is formed in the protective shell B 6 , and the adjusting member B 33  extends out of the main body B 0  from the sliding groove. That is, the adjusting member B 33  can slide in the sliding groove B 61  and the sliding groove B 61  restricts a limit position of the movement of the adjusting member B 33  so that the closing door B 31  is stopped at a proper position. 
     In one embodiment, the closing door B 31  can slide along a direction parallel to the axis of the dust cup component B 1 , and the sliding groove B 61  extends along the direction parallel to the axis of the dust cup component B 1 . 
     In some embodiments, as shown in  FIG. 6 , the dust outlet B 1211  is located at an axial end of the dust cup component B 1 . As shown in  FIG. 12 , the normally open return member B 32  pushes the closing door B 31  toward the dust outlet B 1211 , and the principle of action here can be referred to the principle of action of the spring described above. 
     Specifically, the dust accumulation base A is provided with a trigger (not shown in the figure). After the dust accumulation base A and the cleaning apparatus B are fitted in place, the dust inlet A 01  is butt-jointed to the dust outlet B 1211 , and the trigger triggers the closing component B 3  to close the main suction channel B 011  (the structure of the main suction channel B 011  is shown in  FIG. 13 ). 
     In one embodiment, the trigger is formed on the inner wall of the avoidance area A 7  of the support part A 1 . When the cleaning apparatus B is butt-jointed to the dust accumulation base A, the closing component B 3  of the cleaning apparatus B is partially inserted in the avoidance area A 7 , so that the trigger triggers the closing component B 3  when coming into contact with the closing component B 3 . For example, when the cleaning apparatus B is inserted into the avoidance area A 7  from top to bottom, the trigger pushes the adjusting member B 33  to move upward (away from the dust outlet B 1211 ), so that the closing door B 31  moves upward into the air inlet pipe B 01  to close the main suction channel B 011 . It is understandable that when the cleaning apparatus B of the present application is butt-jointed to the dust accumulation base A, the dust outlet B 1211  can be automatically butt-jointed to the dust inlet A 01 , the main suction channel B 011  can be automatically closed, and the dust outlet lid B 122  can automatically open the dust outlet B 1211 . 
     In summary, in the cleaning apparatus assembly  1000  of the embodiment of the present application, when the cleaning apparatus B is fitted with the dust accumulation base A, the dust inlet A 01  and the dust outlet B 1211  are immediately butt-jointed, and at this time, the unlocking device C triggers the locking mechanism B 123  to be unlocked, and then the dust outlet lid B 122  is driven to automatically open the dust outlet B 1211 . In the meanwhile, the trigger triggers the adjusting member B 33 , and pushes the adjusting member B 33  to move away from the dust outlet B 1211 , so that the closing door B 31  moves toward the close position to close the main suction channel B 011  and the air outlet B 02  of the cleaning apparatus B comes into communication with the chamber in the dust accumulation base A. Under the action of the suction device A 3 , a relatively large suction force is formed in the cleaning apparatus B so that the dust stored in the dust cup component B 1  quickly enters the dust accumulation base A from the dust outlet B 1211  and the dust inlet A 01  which are butt-jointed, thus achieving automatic dust discharging. In this way, the dust outlet lid B 122  does not need to be manually opened, the hands will not get dirty, and the dust can be discharged quickly and efficiently. Moreover, problems such as dust leakage and raising during the dust dumping process and secondary pollution to the environment can be avoided.
