     DETAILED DESCRIPTION OF EMBODIMENTS 
     The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure. 
     It should be noted that, the descriptions associated with, e.g., “first” and “second,” in the present disclosure are merely for descriptive purposes, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature associated with “first” or “second” can expressly or impliedly include at least one such feature. 
     Besides, the meaning of “and/or” appearing in the disclosure includes three parallel schemes. For example, “A and/or B” includes only A, or only B, or both A and B. 
     The present disclosure provides a mobile air conditioner. 
     In an embodiment of the present disclosure, as shown in  FIG. 1  to  FIG. 8 , the mobile air conditioner  100  includes a housing  10  and a storage box  20 . 
     For example, as shown in  FIG. 6 ,  FIG. 8  and  FIG. 9 , the storage box  20  includes a storage cavity  21  and a storage opening  22  in communication with the storage cavity  21 . The storage cavity  21  is usually used for accommodating the remote controller. The remote controller can be stored in the storage cavity  21  through the storage opening  22 , or can be separated from the storage cavity  21  through the storage opening  22 . The storage opening  22  can also be used to store other items, such as mobile phones, antiseptics, and air stimulants. 
     For example, as shown in  FIG. 6 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the housing  10  is provided with a hidden opening  11 . The hidden opening  11  penetrates the wall of housing  10 . The storage box  20  is movably disposed on the housing  10 , and the storage box  20  has a first position extending out of the hidden opening  11  to expose the storage opening  22 , and a second position hidden in the housing  10 . The storage box  20  is movably provided at the hidden opening  11 . The storage box  20  can be rotatably provided on the housing  10 ; alternatively, the storage box  20  can be slidably provided on the housing  10 ; alternatively, the storage box  20  is detachably provided on the housing  10 , and so on. As a result, the storage box  20  is movably provided on the housing  10 . 
     As shown in  FIG. 1  to  FIG. 4 , in the second position (that is, when the storage box  20  is in the second position, this abbreviation is used for description below), the storage box  20  (the side wall) blocks the hidden opening  11  or the storage box  20  is completely moved into the housing  10 , so that the storage box  20  is hidden in the housing  10 . 
     For example, when it is necessary to store or pack the mobile air conditioner  100 , the storage box  20  can be moved to the first position first, so that (the open end or the whole of the storage box  20 ) extends out of the hidden opening  11  and exposes the storage opening  22 , so that the remote control can be stored in the storage box  20 . Subsequently, the storage box  20  is moved to the second position to hide the storage box  20  in the housing  10 , so that the remote controller is hidden/stored in the housing  10 . In this way, hiding the storage box  20  in the housing  10  can reduce the risk of the storage box  20  being collided during transportation, so as to reduce the risk of damage to the storage box  20 . During the use of the mobile air conditioner  100 , the risk of collision/interference between the storage box  20  and the user can be reduced, thereby not only reducing the risk of damage to the storage box  20 , but also improving the user comfort. 
     When the remote controller needs to be used, the storage box  20  can be moved to the first position for the user to take the remote controller. 
     In the mobile air conditioner  100  of the embodiment of the present disclosure, a hidden opening  11  is provided on the housing  10 , and the storage box  20  can be hidden in the housing  10  through the hidden opening  11 , so that the remote control can be hidden/stored in the housing  10 . In this way, it is not only possible to avoid the problem of separately storing/packing the remote control when packaging or transporting the mobile air conditioner  100 , but also to prevent the remote control from being lost during use, thereby improving the storage convenience of the remote control. Moreover, hiding the storage box  20  in the housing  10  can not only reduce the risk of damage to the storage box  20  and the remote control, but also avoid damage to the appearance of the housing  10  (i.e., the mobile air conditioner  100 ), thereby improving user comfort. 
     It should be noted that for the solution of “when in the second position, the storage box  20  is completely moved into the housing  10  to realize that the storage box  20  is hidden in the housing  10 ”, a switch door can be provided at the hidden opening  11  to close/cover the hidden opening  11  when the storage box  20  is in the second position. For example, the switch door is slidably arranged on the inner wall surface of the housing  10  to close or open the hidden opening  11 . Optionally, an escape chute is formed on the inner wall surface of the housing  10 , and the switch door is slidably provided in the escape chute. In this way, not only can the storage box  20  be limited to prevent it from slipping out of the hidden opening  11 , but also the integrity of the housing  10  can be improved to ensure the appearance of the housing  10  and the mobile air conditioner  100 . In a further improvement of this solution, a storage cavity can be provided on the inner wall surface of the housing  10  corresponding to the hidden opening  11  to accommodate the storage box  20 . 
     In the following examples of the present disclosure, as shown in  FIG. 1  to  FIG. 4 , in the second position, the storage box  20  blocks the hidden opening  11 . In the second position, the box wall of the storage box  20  blocks the hidden opening  11 . For example, as shown in  FIG. 2 , the storage box  20  includes a first side wall  23 , and when in the second position, the first side wall  23  covers the hidden opening  11 . In this way, the hidden opening  11  can be covered by the structure of the storage box  20  itself, so that the structure of the mobile air conditioner  100  can be simplified. 
     As shown in  FIG. 2 , the outer wall surface of the first side wall  23  is flush with or approximately flush with the outer wall surface of the housing  10 ; in this way, the risk of collision of the storage box  20  can be further reduced, and the aesthetics of the housing  10  can also be improved. 
     In this embodiment, as shown in  FIG. 1  and  FIG. 5 , the housing  10  is in the shape of a cuboid or substantially in the shape of a cuboid. Optionally, the housing  10  includes a bottom plate, a top housing (i.e., a top plate) opposite to the bottom plate, and an enclosure. The enclosure has a front housing wall, a rear housing wall, a left housing wall and a right housing wall. Optionally, the enclosure includes a front housing and a rear housing, and the front housing and the rear housing are enclosed to form an enclosure. 
     Optionally, the hidden opening  11  can be provided on the top housing (i.e., the top plate) or the enclosure. For example, the hidden opening  11  is provided on the left housing wall or the right housing wall, and the hidden opening  11  can be provided on the front housing or the rear housing. 
     As shown in  FIG. 3  and  FIG. 4 , when in the second position, the length direction of the storage box  20  is parallel or substantially parallel to the housing wall where the hidden opening  11  is located. 
     In this embodiment, as shown in  FIG. 9  to  FIG. 11 , the storage box  20  is in the shape of a cuboid or substantially in the shape of a cuboid; the storage box  20  is vertically arranged in the second position. 
     Further, as shown in  FIG. 12  and  FIG. 13 , a reinforcing ring protrusion  12  is formed on the inner wall surface of the housing  10 , and the reinforcing ring protrusion  12  is arranged on the periphery of the hidden opening  11 . In this way, not only the structural strength of the housing wall at the hidden opening  11  can be enhanced, but also the risk of damage to the housing  10  at the hidden opening  11  can be reduced. It is also convenient to provide a structure matching with the storage box  20  on the housing  10 . 
     For example, as shown in  FIG. 12  and  FIG. 13 , the reinforcing ring protrusion can be formed by folding the periphery of the hidden opening  11  inward. 
     Optionally, the reinforcing ring protrusion is in the shape of a plate or a sheet. 
     Further, the storage box  20  and the housing  10  are provided with a first limiting structure, and the first limiting structure is used to limit the storage box  20  and the housing  10  in the second position. In this way, the storage box  20  can be prevented from moving too much and the storage box  20  is positioned at the second position, and the storage box  20  can also be prevented from being buckled/sunk into the housing  10 . 
     In an exemplary embodiment, there are multiple forms of the first limiting structure, including but not limited to one or more of a magnetic attraction structure, a snap-fit structure, and a stop structure, etc., which will be described with examples below. 
     For example, as shown in  FIG. 9 ,  FIG. 12  and  FIG. 13 , the first limiting structure includes a first blocking protrusion  231  provided on the storage box  20  and a second blocking protrusion  121  provided on the inner wall surface of the housing  10 . The second blocking protrusion  121  protrudes toward the center of the hidden opening  11 . In the second position, the first blocking protrusion  231  abuts the second blocking protrusion  121  to limit the storage box  20  and prevent its excessive movement. 
     In this embodiment, as shown in  FIG. 9 , the first side wall  23  protrudes from the other side walls (including the second side wall  24 ) to form a first blocking protrusion  231 . 
     In this embodiment, as shown in  FIG. 12  and  FIG. 13 , the second blocking protrusion  121  can be protruded on the inner (ring) surface of the reinforcing ring protrusion. 
     Optionally, as shown in  FIG. 12  and  FIG. 13 , the second blocking protrusion  121  extends along the side edge of the hidden opening  11 . 
     Optionally, as shown in  FIG. 12  and  FIG. 13 , the inner side (ring) surface of the reinforcing ring protrusion is further provided with a reinforcing rib (not shown) connecting the second blocking protrusion  121  and the reinforcing ring protrusion. 
     In other embodiments, the first blocking protrusion  231  can also cooperate with other structures, for example, the hidden opening  11  is a stepped hole. 
     Further, the storage box  20  and the housing  10  are provided with a second limiting structure, and the second limiting structure is used to limit the storage box  20  and the housing  10  in the first position. In this way, excessive movement of the storage box  20  can be prevented, so that the storage box  20  is positioned in the first position, so as to prevent the storage box  20  from being separated from the housing  10 . In other embodiments, the second limiting structure may not be provided, and the storage box  20  can be taken out from the hidden opening  11  when necessary (using a remote controller). 
     In an exemplary embodiment, there are many forms of the second limiting structure, including but not limited to one or more of a magnetic attraction structure, a buckle structure, and a stop structure, etc. The following will give an example in conjunction with the movement form of the storage box  20  and the like. 
     It should be noted that, in some embodiments, in order to simplify the structure, the first limiting structure and the second limiting structure may share a part of the structure. 
     Further, as shown in  FIG. 1  to  FIG. 8 , the storage box  20  is rotatably disposed in the hidden opening  11  so that the storage box  20  has a first position and a second position. For example, when necessary, the storage box  20  can be driven to rotate to the first position, so that the open end of the storage box  20  extends out of the hidden opening  11  to expose the storage opening  22 . Thus, the remote control is taken out or the storage box  20  is put into the storage cavity  21 . When necessary, the storage box  20  can be driven to rotate to the second position, so that the storage box  20  is hidden from the housing  10 . In this way, the storage opening  22  can be exposed or the storage box  20  can be hidden through the rotation of the storage box  20 , and the operation is simple and convenient. Moreover, the rotation of the storage box  20  requires less space for operation, which is beneficial to saving the internal space of the housing  10 . 
     For example, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the inner wall surface of the housing  10  is provided protrudingly with a support protrusion  13 . The support protrusion  13  extends away from the housing wall where the hidden opening  11  is located, and the storage box  20  is rotatably connected to the support protrusion  13 , so that the storage box  20  is rotatably disposed on the housing  10 . In this way, by arranging the support protrusion  13  on the inner wall surface of the housing  10 , it is convenient to implement the rotational connection with the storage box  20 , and can help to enhance the structural strength of the rotational connection structure between the storage box  20  and the housing  10 . 
     Optionally, the support protrusion  13  is in the shape of a plate or a sheet. 
     Optionally, the support protrusion  13  is integrally formed with the reinforcing ring protrusion  12  to simplify the structure. 
     Further, as shown in  FIG. 7  to  FIG. 11 , a rotating shaft  241  is protruded on the storage box  20 , a rotating hole  131  is provided on the support protrusion  13 , and the rotating shaft  241  is rotatably disposed in the rotating hole  131 , so that the storage box  20  is rotatably connected to the support protrusion  13 . In this way, it is beneficial to set the installation structure of the rotating shaft  241  and the rotating hole  131 . In other embodiments, the rotating shaft  241  may also be disposed on the support protrusion  13 , and correspondingly, the rotating hole  131  is disposed on the storage box  20 . 
     Optionally, as shown in  FIG. 9  to  FIG. 11 , the rotating hole  131  penetrates through the support protrusion  13 . 
     For example, as shown in  FIG. 9  to  FIG. 11 , the storage box  20  further includes two second side walls  24  adjacent to the first side wall  23 , and the two second side walls  24  are respectively connected to two sides of the first side wall  23 . The rotating shaft  241  is protruded from the outer wall surface of the second side wall  24 . Optionally, a reinforcing protrusion (not shown) is provided at the connection between the rotating shaft  241  and the second side wall  24 , to enhance the connection strength between the rotating shaft  241  and the second side wall  24 , such that the connection stability of the rotating shaft  241  is improved. 
     Further, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , there are two support protrusions  13 , and the two support protrusions  13  are respectively provided on opposite sides of the hidden opening  11 . 
     The storage box  20  is disposed between the two support protrusions  13 , and two sides of the storage box  20  are respectively rotatably disposed on the two support protrusions  13 . 
     In this way, the rotational stability of the storage box  20  can be enhanced. 
     It should be noted that, in other embodiments, the position and number of the support protrusions  13  can also be designed in other ways. For example, the support protrusion  13  can be provided on one side of the hidden opening  11 . The number of the support protrusions  13  can be set to one or more. One side of the storage box  20  (e.g., the side opposite to the side where the storage opening  22  is located) is rotatably provided on the support protrusion  13 ; and so on. 
     Further, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the support protrusion  13  is also provided with a guide groove  132  communicating with the rotating hole  131 , one end of the guide groove  132  away from the rotating hole  131  has an opening, and the guide groove  132  is used to guide the rotating shaft  241  to slide into the rotating hole  131 . 
     For example, when installing the storage box  20 , the rotating shaft  241  can be slid into the guide groove  132  through the opening of the guide groove  132 , and can be slid into the rotating hole  131  through the guide groove  132 . In this way, the rotating shaft  241  can be easily assembled into the rotating hole  131 . 
     Optionally, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the guide groove  132  is flared, the rotating shaft  241  can be easily slid into the guide groove  132  during assembly, so that the rotating shaft  241  can be inserted into the rotating hole  131 . 
     Optionally, the guide groove  132  is disposed on the side of the rotating hole  131  away from the housing wall where the hidden opening  11  is located; thus, it is additionally convenient to assemble the rotating shaft  241 . 
     Optionally, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the guide groove  132  penetrates through the support protrusion  13 . 
     Optionally, the guide groove  132  is smoothly connected with the rotating hole  131 . 
     For example, as shown in  FIG. 12  and  FIG. 13 , a connection between the guide groove  132  on at least one of the support protrusions  13  and the rotating hole  131  is provided with a locking protrusion (not shown). The locking protrusion is used to limit the rotating shaft  241  to prevent it from escaping from the rotating hole  131 . In this embodiment, only one of the support protrusions  13  is provided with the locking protrusion. 
     For example, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , a thickening portion  133  is protruded on the periphery of the rotating hole  131  on the support protrusion  13 . In this way, on the one hand, the structural strength of the rotating hole  131  can be improved, and the wear resistance of the rotating hole  131  can be increased. On the other hand, the contact area between the rotating shaft and the rotating hole  131  can also be increased, thereby increasing the rotational stability of the storage box. Optionally, the thickening portion  133  is provided on the side of the support protrusion  13  facing away from the storage box  20 . 
     For example, as shown in  FIG. 12  and  FIG. 13 , a protrusion  134  is provided on the side of the support protrusion  13  facing the storage box  20  (i.e., the inner side of the support protrusion  13 ). The protrusion  134  is used to abut the outer wall surface of the second side wall  24  during the rotation of the storage box  20 . 
     Optionally, the protrusion  134  is disposed proximally to the rotating hole  131  and the guide groove  132 , so that the structural strength of the support protrusion  13  at the rotation hole  131  and the guide groove  132  can be improved. 
     Optionally, the protrusion  134  extends in a direction away from the hidden opening  11 , so as to improve the structural strength of the support protrusion  13  at the rotating hole  131  and the guide groove  132 . 
     It can be understood that during the rotation of the storage box  20 , the protrusion  134  can abut the outer wall surface of the second side wall  24 . In this way, direct contact between the inner side surface of the support protrusion  13  and the outer wall surface of the second side wall  24  can be avoided. Therefore, the contact area between the support protrusion  13  and the outer wall surface of the second side wall  24  during rotation can be reduced, so as to reduce the rotation resistance of the storage box  20 . 
     Optionally, the protrusion  134  is high in the middle and low at both ends, so as to further reduce the rotational resistance of the storage box  20 . 
     Optionally, there are two protrusions  134 , and the two protrusions  134  are respectively provided on opposite sides of the rotating hole  131 . As shown in  FIG. 13 , one of the protrusions  134  is provided on the upper side of the rotating hole  131 , and the other protrusion  134  is provided on the lower side of the rotating hole  131 . 
     Further, as shown in  FIG. 12  and  FIG. 13 , the inner wall surface of the housing  10  is further provided protrudingly with a connecting protrusion  14 , and the connecting protrusion  14  is disposed on one side of the hidden opening  11  to connect the two support protrusions  13 . In this way, the structural strength and stability of the support protrusions  13  can be enhanced, so that the rotational stability of the storage box  20  can be enhanced. It can be understood that the two support protrusions  13  and the connecting protrusions  14  are enclosed on the outside of the storage box  20 , and can also protect the storage box  20 , to reduce the risk of damage caused by the collision between the storage box  20  and other components in the housing  10 . 
     Optionally, as shown in  FIG. 12  and  FIG. 13 , the connecting protrusion  14  is integrally formed with the reinforcing ring protrusion  12 . Optionally, the connecting protrusion  14  is in the shape of a plate or a sheet. 
     Further, the rotating shaft  241  is disposed close to the first side wall  23 . In this way, on the one hand, the protruding length of the support protrusion  13  can be reduced, and the rotation stability of the storage box  20  can be improved. In this embodiment, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the rotating shaft  241  is provided on the side of the second side wall  24  close to the first side wall  23 . 
     Further, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the storage box  20  also has a box bottom end opposite to its open end, and the rotating shaft  241  is disposed at the box bottom end. In this way, the rotation range of the storage box  20  can be reduced, so as to save the inner space of the housing  10 . 
     Optionally, as shown in  FIG. 7 ,  FIG. 8 ,  FIG. 12  and  FIG. 13 , the rotating shaft  241  is disposed adjacent to the connection between the first side wall  23  and the second side wall  24 . 
     For example, as shown in  FIG. 12  and  FIG. 13 , the hidden opening  11  has a first side edge (not shown) corresponding to the open end of the storage box  20 , a second side edge (not shown) opposite to the first side edge, and two third side edges (not shown) adjacent to the first side edge. Optionally, the hidden opening  11  is a square hole or is substantially a square hole. 
     It can be understood that as shown in  FIG. 7  and  FIG. 8 , when the storage box  20  is rotated from the second position to the first position, the open end of the storage box  20  will move in a direction close to the first side edge of the hidden opening  11 . In this way, interference between the open end of the storage box  20  and the first side edge of the hidden opening  11  is avoided. Thus, when in the second position, the open end of the storage box  20  is spaced from the first side edge of the hidden opening  11  to avoid interference with the edge (i.e., the first side edge) of the hidden opening  11  when the storage box  20  is rotated. Alternatively, the opening end of the second side wall  24  is formed with an avoidance notch  242  at the connection with the first side wall  23 . The avoidance notch  242  avoids the edge of the hidden opening  11  (i.e., the first side edge) when the storage box  20  is rotated, so as to avoid interference with the edge of the hidden opening  11  (i.e., the first side edge) when the storage box  20  is rotated. Alternatively, the open end of the storage box  20  is inclined to avoid the edge (i.e., the first side edge) of the hidden opening  11  when the storage box  20  is rotated, to avoid interference with the edge (i.e., the first side edge) of the hidden opening  11  when the storage box  20  is rotated. Other escape structures may also be provided on the storage box  20  and/or the housing  10  to avoid interference with the edge (i.e., the first side edge) of the hidden opening  11  when the storage box  20  is rotated. 
     In some embodiments, as shown in  FIG. 9  to  FIG. 11 , the open end of the second side wall  24  is formed with an avoidance notch  242  at the connection with the first side wall  23 , and the avoidance notch  242  extends for a predetermined length in the extending direction of the first side wall  23 . Optionally, the avoidance notch  242  is a stepped notch. 
     In this embodiment, as shown in  FIG. 9  to  FIG. 11 , the open end of the first side wall  23  protrudes from the open end of the second side wall  24  to form the avoidance notch  242 . Optionally, the open end of the first side wall  23  also protrudes from the open end of the third side wall (i.e., the side wall of the storage box  20  opposite to the first side wall  23 ). 
     Further, as shown in  FIG. 9  to  FIG. 11 , a gripping notch  243  is formed on the open end of the side wall of the storage box  20 , and the gripping notch  243  is recessed toward the bottom of the storage cavity  21 . In this way, by providing the gripping notch  243 , when the remote control is stored in the storage cavity  21 , the gripping notch  243  can expose the upper end of the remote control, so that it is convenient for the user to store or take the remote control. 
     For example, as shown in  FIG. 9  to  FIG. 11 , the gripping notch  243  is provided on the second side wall  24 , so that it is convenient for the user to hold the remote control. 
     Optionally, as shown in  FIG. 9  to  FIG. 11 , each second side wall  24  is provided with a gripping notch  243 , and the two gripping notch  243  are opposite to each other, so that it is additionally convenient for the user to hold the remote control. 
     Optionally, the gripping notch  243  is provided at the middle of the second side wall  24 . 
     Further, as shown in  FIG. 3 ,  FIG. 4 ,  FIG. 7  and  FIG. 8  to  FIG. 13 , a guide structure is provided on the storage box  20  and the housing  10 , and the guide structure is used to guide the rotation of the storage box  20 . For example, the guide structure can be used to guide the storage box  20  to rotate from the first position to the second position; alternatively, the guide structure can be used to guide the storage box  20  to rotate from the second position to the first position. In this way, the rotational stability of the storage box  20  can be improved. 
     Further, as shown in  FIG. 12  and  FIG. 13 , an inner wall surface of the housing  10  is provided protrudingly with a guide support portion  15 , a guide protrusion  151  is provided on one side of the hidden opening  11 . The guide structure includes a guide protrusion  151  laterally protruding from the guide support portion  15 , and a guide groove  144  provided on the outer wall surface of the storage box  20 , and the guide protrusion  151  is slidably provided in the guide groove  244 , and is configured to guide the rotation of the storage box  20 . For example, the guide protrusion  151  is provided on the side of the guide support portion  15  facing the hidden opening  11 , and the guide groove  244  is provided on the outer wall surface of the second side wall  24 . In this way, the storage box  20  can be guided to rotate with a simple structure. 
     Optionally, the guide groove  244  is an arc groove. 
     Optionally, the distal end of the guide protrusion  151  is provided with a spherical portion to reduce frictional force and rotational resistance. Optionally, the spherical portion may be spherical, spheroid, ellipsoid, or the like. 
     For example, the guide groove  244  has an outer end close to the first side wall  23  and an inner end away from the first side wall  23 , and the groove depth of the guide groove  244  increases from the outside to the inside. In this way, it is convenient to turn the storage box  20  from the second position to the first position, and it is also beneficial to limit the storage box  20  and the housing  10  when the storage box  20  is in the second position. 
     Optionally, the groove bottom of the guide groove  244  is an inclined surface or an arc surface. 
     Optionally, the guide support portion  15  is in the shape of a plate or a sheet. 
     Optionally, the guide support portion  15  is integrally formed with the reinforcing ring protrusion  12  to simplify the structure. 
     Further, as shown in  FIG. 12  and  FIG. 13 , there are two guide support portions  15 , the two guide support portions  15  are respectively disposed on opposite sides of the hidden opening  11 , and guide grooves  244  are provided on the outer wall surfaces of the two second side walls  24  of the storage box  20 . Optionally, each guide support portion  15  is provided with at least one guide protrusion  151 . Optionally, the two guide support portions  15  are disposed opposite to each other. 
     In this way, the rotational stability of the storage box  20  can be enhanced. 
     Further, as shown in  FIG. 7  to  FIG. 10 , the guide groove  244  is disposed adjacent to the open end of the storage box  20 . 
     For example, the gripping notch  243  breaks the guide groove  244  to form two guide sub-grooves (not shown), and a fracture (not shown) is formed between the two guide sub-grooves. In this way, when the storage box  20  is rotated, the guide protrusions  151  can be rotated within the fracture, thereby reducing the rotation resistance of the storage box  20 . 
     Further, the guide protrusion  151  can be shared by the guide structure and the first limiting structure to simplify the structure. For example, as shown in  FIG. 5  to  FIG. 13 , the first limiting structure further includes a guide protrusion  151  and a limiting groove  2441  provided at the bottom of the guide groove  244 . In the second position, the guide protrusion  151  is limited to the limiting groove  2441 . In this way, the storage box  20  can be positioned/fixed at the second position. It can be understood that when the storage box  20  needs to be rotated, the user can force (i.e., pull) the storage box  20  to make the guide protrusion  151  escape from the limiting groove  2441 . 
     It should be noted that when the storage box  20  moves (e.g., rotates) to the second position, the first blocking protrusion  231  on the storage box  20  abuts the second blocking protrusion  121  on the housing  10  to prevent the storage box  20  from moving excessively. Meanwhile, the guide protrusion  151  slides into the limiting groove  2441  to further limit the storage box  20  and the housing  10  to position/fix the storage box  20  in the second position. 
     In other embodiments, the guide structure can also be provided in other forms or other positions. For example, the guide structure includes a guide arc protrusion on the second side wall  24  and a guide notch on the second side edge of the hidden opening  11 . The guide arc protrusion is arc-shaped, and the guide arc protrusion is slidably disposed in the guide notch to guide the rotation of the storage box  20 . Optionally, the height of the guide arc protrusion increases from the inside to the outside, which is not repeated herein. 
     In this embodiment, as shown in  FIG. 12  and  FIG. 13 , the second blocking protrusion  121  is disposed corresponding to the third side edge of the hidden opening  11 . For example, the second blocking protrusion  121  is spaced apart from the second side edge of the hidden opening  11 . An avoidance space is formed between the second blocking protrusion  121  and the second side edge of the hidden opening  11 . In this way, on the one hand, the avoidance space can avoid the first blocking protrusion  231  when the storage box  20  is rotated. On the other hand, when the storage box  20  is assembled from the inside of the housing  10 , the first blocking protrusions  231  on the storage box  20  can pass through the avoidance space and be assembled to the outside of the housing  10 . 
     For example, there are two second blocking protrusions  121 , and the two second blocking protrusions  121  are respectively disposed corresponding to the two third side edges of the hidden opening  11 . 
     Further, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 7  to  FIG. 11 , the second limiting structure includes a stop protrusion  26  provided on the storage box  20 , and the stop protrusion  26  is provided in the housing  10 . In the first position, the stop protrusion  26  is in contact with the inner wall surface of the housing  10  to limit the storage box  20  and prevent it from moving too much. For example, when the storage box  20  is rotated to the first position, the stop protrusion  26  is in contact with the inner wall surface of the housing  10 . In this way, depending on the structure of the housing  10 , the housing  10  is matched with the stop protrusion  26  to form the second stop structure, the structure can be simplified. In other embodiments, a matching structure may also be provided on the inner wall surface of the housing  10  to abut the stop protrusion  26  at the first position. 
     For example, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 7  to  FIG. 11 , the stop protrusion  26  is disposed away from the rotation axis of the storage box  20  to increase the distance between the stop protrusion  26  and the rotation axis of the storage box  20 , to increase the moment arm, thus the risk of damage to the stop protrusion  26  and the rotating shaft  241  is reduced. 
     For example, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 7  to  FIG. 11 , the stop protrusion  26  is provided on the second side wall  24  of the storage box  20 . Optionally, the stop protrusion  26  is disposed close to the open end of the storage box  20 , and the stop protrusion  26  is disposed away from the first side wall  23 . 
     Further, the stop protrusion  26  is rotatably provided on the storage box  20 . In this way, when the storage box  20  is rotated to the first position, the stop protrusion  26  can be rotated in the process of interacting with the inner wall surface of the housing  10  so as to be rotated to a suitable position to abut the inner wall surface of the housing  10 , thereby reducing the design accuracy and difficulty (that is, when designing, it is not necessary to consider the relationship between the inclination angle of the contact surface of the stop protrusion  26  and the maximum rotation angle of the storage box  20 ). 
     For example, the stop protrusion  26  may be in the shape of a plate, a sheet, or a block. In this embodiment, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 7  to  FIG. 11 , the stop protrusion  26  is in the shape of a bent plate, which includes a rotating portion and a stop portion. The rotating portion is rotatably connected to the storage box  20 , and the stop portion is used for abutting the inner wall surface of the housing  10 . 
     In other embodiments, the stop protrusion  26  can also be set in a cylindrical shape or a quasi-cylindrical shape. At this time, the stop protrusion  26  can be integrally formed with the storage box  20  (it is not necessary to be rotatably connected). 
     Further, as shown in  FIG. 1 ,  FIG. 2  and  FIG. 7  to  FIG. 11 , there are two stop protrusions  26 . The two stop protrusions  26  are respectively disposed on the outer wall surface of the second side wall  24  of the storage box  20 . In this way, the force applied to the storage box  20  in the first position can be more symmetrically balanced, thereby reducing the risk of damage to the stop protrusion  26 . 
     Further, as shown in  FIG. 1 ,  FIG. 2 ,  FIG. 5 ,  FIG. 6 ,  FIG. 10  and  FIG. 11 , the first side wall  23  is provided with a gripping structure, and the gripping structure is used for the user to grasp. In this way, the user can drive the storage box  20  to rotate through the gripping structure, so as to facilitate the user to apply force, thereby improving the user&#39;s comfort. 
     For example, as shown in  FIG. 1 ,  FIG. 2 ,  FIG. 5 ,  FIG. 6 ,  FIG. 10  and  FIG. 11 , the gripping structure includes a buckle handle  232  formed by the indentation of the first side wall  23 . 
     In this embodiment, as shown in  FIG. 11 , the buckle handle  232  has a buckle opening  2321 . The buckle handle  232  includes a first buckle wall  2322  and a second buckle wall  2323  disposed on opposite sides of the buckle opening  2321 . The first buckle wall  2322  extends obliquely in a direction away from the second buckle wall  2323  from the outside to the inside. The second buckle wall  2323  extends obliquely toward the first buckle wall  2322  from the outside to the inside. The direction towards the bottom of the buckle handle  232  is inward, and the direction away from the bottom of the buckle handle  232  is outward. 
     In this embodiment, as shown in  FIG. 11 , the first buckle wall  2322  extends obliquely from the outside to the inside in a direction away from the second buckle wall  2323 , so that the user interacts with the first buckle wall  2322  to drive the storage box  20  to move. Optionally, the first buckle wall  2322  is disposed on the side of the buckle opening  2321  toward the open end of the storage box  20 . 
     In this embodiment, as shown in  FIG. 11 , the second buckle wall  2323  extends obliquely toward the first buckle wall  2322  from the outside to the inside, so as to guide the user to interact with the first buckle wall  2322 . 
     In this embodiment, the buckle handle  232  further includes a buckle bottom  2324 , and the buckle bottom  2324  is disposed opposite to the buckle opening  2321 . 
     The gripping structure can also be provided in other structural forms, such as a lifting handle, etc., as long as it can be grasped by the user. 
     Further, as shown in  FIG. 11 , guide ribs  25  are protruded on the inner wall surface of the storage cavity  21 . The guide ribs  25  extend along the depth direction of the storage cavity  21 . The height of the guide ribs  25  increases in the direction from the storage opening  22  to the bottom of the storage cavity  21 . For example, the height of the guide rib  25  increases in the insertion direction of the remote controller. In this way, when storing the remote control, the guide rib  25  can be used to guide the remote control to be inserted into the storage cavity  21 , so that the remote control can be stored in the storage cavity  21 . After the remote controller is stored, the guide ribs  25  can also be used to limit the remote controller to prevent the remote controller from shaking, so as to avoid noise caused by the shaking of the remote controller during the process of moving the mobile air conditioner  100 . 
     For example, the width of the guide rib  25  increases in the direction from the storage opening  22  to the bottom of the storage cavity  21 . In this way, on the one hand, the contact area between the guide rib  25  and the remote control can be increased to enhance the limiting effect, and on the other hand, the structural strength of the storage box  20  can also be increased. 
     For example, there are two guide ribs  25 . The two guide ribs  25  are respectively disposed on the inner wall surfaces of the two second side walls  24 . 
     It can be understood that when the remote controller is stored in the storage box  20 , the mobile air conditioner  100  is transported, the remote controller may be separated from the storage cavity  21  from the storage opening  22  and fall into the housing  10 . 
     For example, the outer wall surface of the storage box  20  is provided with a thinning groove  245  corresponding to the guide rib  25 , so that the thickness of the box wall of the storage box  20  can be uniform or relatively uniform. 
     In order to solve the problem, the mobile air conditioner  100  further includes a limiting member, and the limiting member is cooperatively connected with the storage box  20  for preventing the remote controller from being separated from the storage cavity  21 . Optionally, the limiting member is a box cover or protective foam (which can be sandwiched between the remote control and the inner wall surface of the storage cavity  21 ) or the like. 
     Alternatively, the housing  10  includes a first housing wall (i.e., the upper housing wall in the state of  FIG. 3 ) that is opposite to the storage opening  22  in the first position. The hidden opening  11  is disposed close to the first housing wall to prevent the remote controller from being separated from the storage cavity  21 . Optionally, the distance between the storage opening  22  and the first housing wall is smaller than the length of the remote control. 
     Alternatively, the inner wall surface of the housing  10  is provided with a shift protrusion, and the shift protrusion is disposed corresponding to the storage opening  22  for preventing the remote control from being separated from the storage cavity  21 . 
     It should be noted that in this embodiment, the use process of the storage box  20  is roughly as follows: 1) when the storage box  20  is rotated to the second position, the first blocking protrusion  231  on the storage box  20  is in contact with the second blocking protrusion  121  on the housing  10 , and the guide protrusion  151  is limited to the limiting groove  2441 ; 2) when the storage opening  22  needs to be exposed, the user drives the storage box  20  to rotate through the buckle handle  232 , and the guide protrusion  151  disengages from the guide groove  244  and slides along the guide groove  244 , until the stop protrusion  26  abuts the inner wall surface of the housing  10 , the storage box  20  is rotated to the second position and the storage opening  22  is exposed. 
     For example, the storage box  20  further includes a bottom wall  27  disposed opposite to the storage opening  22 , and a through hole  271  is formed on the bottom wall  27 . Optionally, the through hole  271  is disposed close to the first side wall  23 . In this way, it is easy to open the mold. 
     In order to further understand the technical solutions of the present disclosure, as shown in  FIG. 14  and  FIG. 15 , and  FIG. 7 ,  FIG. 8 ,  FIG. 3  and  FIG. 4 , the present disclosure further provides a method for assembling a storage box  20 , including following operations. 
     At Operation S 100 , an open end of the storage box  20  is inserted into a hidden opening  11  from an inner side of a housing  10 . 
     For example, as shown in  FIG. 14  and  FIG. 15 , the storage box  20  is inclined in the housing  10 , and the open end of the storage box  20  (i.e., the upper end in  FIG. 15 ) faces the hidden opening  11 . The storage box  20  is subsequently moved to the direction close to the hidden opening  11 , so that the open end of the storage box  20  is inserted into the hidden opening  11  from the inner side of the housing  10 , and moved to the outside of the housing  10 . The first blocking protrusion  231  of the storage box  20  can pass through the avoidance space. 
     At Operation S 200 , the rotating shaft  241  on the storage box  20  is assembled into the rotating hole  131  through the guide groove  132 . 
     For example, after the operation S 100 , as shown in  FIG. 7  and  FIG. 8 , it is continued to control the bottom end of the storage box  20  (i.e., the lower end in  FIG. 15 ) to move towards the direction close to the hidden opening  11 . The rotating shaft  241  slides into the guide groove  132  through the opening of the guide groove  132 , and slides into the rotating hole  131  through the guide groove  132 . 
     It should be noted that after the rotating shaft  241  is assembled into the rotating hole  131 , the assembly of the storage box  20  is completed, and the storage box  20  is in the second position at this time. 
     Optionally, as shown in  FIG. 3  and  FIG. 4 , the method further includes operation S 300 , which includes controlling the rotation of the storage box  20  and rotating the open end of the storage box  20  into the hidden opening  11 , so that the first blocking protrusion  231  on the storage box  20  is in contact with the second blocking protrusion  121  on the housing  10 . The guide protrusion  151  slides into the limiting groove  2441  to rotate the storage box  20  to the first position, so that the storage box  20  is hidden from the housing  10 . 
     In this way, the assembly of the storage box  20  is simple and convenient. 
     In another embodiment of the present disclosure, the storage box  20  is slidably disposed on the housing  10 , so that the storage box  20  has a first position and a second position. 
     In this embodiment, further, the hidden opening  11  is close to the housing wall adjacent to the housing wall where the hidden opening  11  is located, and the storage box  20  is slidably disposed on the housing wall adjacent to the housing wall where the hidden opening  11  is located. In this way, the structure is simplified. In an example, the hidden opening  11  is provided on the left or right housing wall of the housing  10 . The hidden opening  11  is provided close to the front housing wall or the rear housing wall of the housing  10 , and the storage box  20  is slidably disposed on the inner wall surface of the front housing wall or the rear housing wall. 
     In this embodiment, further, the storage box  20  is slidably connected to the inner wall surface of the housing  10  through the guide rail structure. Optionally, the storage box  20  is slidably connected to the inner wall surface of the housing  10  through a double guide rail structure. 
     As shown in  FIG. 16 , in another exemplary embodiment of the present disclosure, the mobile air conditioner  100  includes a housing  10  and a cross-flow fan (not shown). The housing  10  is provided with an indoor air inlet  11   c,  and the top of the housing  10  is provided with an indoor air outlet  12   c.  An indoor air duct communicating the indoor air inlet  11   c  with the indoor air outlet  12   c  is formed inside the housing  10 . The cross-flow fan is installed in the indoor air duct. In the above technical solutions, the indoor air outlet  12   c  is provided on the top of the housing  10 . When the cross-flow fan is running, the indoor air enters the indoor air duct from the indoor air inlet  11   c,  and then blows out from the indoor air outlet  12   c  at the top. When the indoor air needs rapid heat exchange, the rotation speed of the cross-flow fan can be directly increased to increase the air output from the indoor air outlet  12   c.  Since the indoor air outlet  12   c  is provided on the top of the housing  10 , when the air is blown out, it will not directly act on the user. On the premise of ensuring that there is sufficient air volume for cooling and heating indoor air, and the cold air or hot air blown from the indoor air outlet  12   c  is prevented from directly blowing on the user, so as to prevent the user from feeling uncomfortable, such as excessive cold and overheating, and optimize the user experience. 
     As shown in  FIG. 16  and  FIG. 17 , in order to implement the heat exchange function of the mobile air conditioner  100 , an indoor heat exchanger  4  needs to be provided on the air inlet of the volute assembly  3 . When the cross-flow fan rotates, the indoor air enters the interior of the housing  10  from the indoor air inlet  11   c,  and enters the indoor air duct after heat exchange with the indoor heat exchanger  4 . 
     The indoor air inlet  11   c  is optionally provided at the front or the rear of the housing  10 . During the actual use of the mobile air conditioner  100 , the user can move the position of the mobile air conditioner  100  according to actual needs. Take the direction the user is facing as the front, when the indoor air inlet  11   c  is provided at the front of the housing  10 , the cross-flow fan directly extracts the air on the side of the user for heat exchange. A weak airflow is formed in the room so that the ambient temperature in the area where the user is located quickly reaches the target value. When the indoor air inlet  11   c  is provided at the rear of the housing  10 , the air on the user&#39;s side will not form airflow, and follow the ambient temperature to change evenly and slowly, improving comfort. 
     As shown in  FIG. 16 ,  FIG. 21  and  FIG. 22 , the indoor air outlet  12   c  is provided with a guide grille  2   c,  and the guide grille includes  2   c  a plurality of longitudinal grille strips  21   c  extending along a length direction of the indoor air inlet  11   c.  The longitudinal grille strips  21   c  are inclined forwardly, that is, the direction of air outlet is consistent with the inclination direction of the longitudinal grille strips  21   c.  Since the longitudinal grille strips  21   c  are inclined forward, the hot air or cold air formed after the heat exchanger treatment directly acts on the upper part of the side where the user is located. The hot air or cold air will quickly exchange heat with the indoor ambient air during the blowing process, so that the ambient temperature on the user&#39;s side can quickly reach the target value. While the ambient temperature on the user&#39;s side is prioritized, the cold air or hot air blown from the indoor air outlet  12   c  is prevented from blowing directly on the user. 
     The guide grille  2   c  further includes a plurality of horizontal grille strips  22   c  extending along a width direction of the indoor air outlet  12   c.  The horizontal grille strips  22   c  and the longitudinal grille strips  21   c  are alternately arranged, and the longitudinal grille strips  21   c  protrude upward from the horizontal grille strips  22   c.  That is, the guide grille  2   c  includes an inner grille layer and an outer grille layer. The inner grille layer is formed by crisscrossing longitudinal grille strips  21   c  and horizontal grille strips  22   c,  and the outer grille is formed by the parts of the longitudinal grille strips  21   c  protruding outward from the horizontal grille strips  22   c.  The crisscrossed inner grille can make the air outlet more uniform and has a dust-proof effect, and the outer grille is more aesthetically appealing, and has the effect of guiding the air and reducing the loss of air volume. 
     As shown in  FIG. 17 ,  FIG. 18  and  FIG. 19 , the mobile air conditioner  100  further includes a volute assembly  3 , and the volute assembly  3  includes a volute  31  and a volute cover  32 , and the volute  31  and the volute cover  32  cooperate to form an indoor air duct. That is, the volute assembly  3  is formed by splicing the volute  31  and the volute cover  32 . When installing the cross-flow fan, it is possible to first fix the cross-flow fan with the volute  31  or the volute cover  32 , and then combine the volute  31  and the volute cover  32 . The cross-flow fan is provided in the indoor air duct formed by splicing the volute  31  and the volute cover  32 . 
     The mobile air conditioner  100  further includes an indoor heat exchanger  4  provided on the air inlet of the volute assembly  3 . The volute cover  32  includes a top plate  321  disposed above the indoor heat exchanger  4 , and the top plate  321  is recessed downward on the air outlet of the indoor heat exchanger  4  to form a water diversion groove  322 . The air treated by the indoor heat exchanger  4  is blown out from the top, which makes it easy to exchange heat with the ambient air to form condensed water. The water diversion groove  322  is provided to collect the condensed water. The top plate  321  shields the indoor heat exchanger  4  to prevent the condensed water from dripping on the indoor heat exchanger  4 , thereby preventing the condensed water from entering the indoor air duct. 
     The water diversion groove  322  is surrounded by the first side wall  322   a,  the bottom plate  322   b  and the second side wall  322   c.  The air outlet of the volute assembly  3  is formed between the first side wall  322   a  and the air duct plate of the volute  31 , and the air outlet is connected to the indoor air outlet  12   c.  The hot air or cold air is prevented from overflowing from the gap between the air outlet and the indoor air outlet  12   c,  which affects the air outlet effect of the entire mobile air conditioner  100 . 
     The top plate  321  is provided with a water-stop flange  323  with an opening on one side, and the opening of the water-stop flange  323  faces the water diversion groove  322 . The condensed water formed at the indoor air outlet  12   c  will adhere to the top plate  321  and accumulate and flow on the top plate  321 . The water-stop flange  323  provided on the top plate  321  can restrict the flow direction of the condensed water. The condensed water flows down the second side wall  322   c  of the water diversion groove  322  and enters the water diversion groove  322  to prevent the condensed water from flowing down from the side of the top plate  321  to the indoor heat exchange air duct. The water-stop flange  323  can be provided on the edge of the top plate  321 , and the shape of the water-stop flange  323  and the connection position between the water-stop flange  323  and the top plate  321  can also be designed according to specific needs. 
     The volute cover  32  further includes a first side plate  324  and a second side plate  325  respectively disposed at both ends of the top plate  321 . The bottom of the water diversion groove  322  is inclined downward from the second side plate  325  to the first side plate  324 . The first side plate  324  is provided with a water diversion notch  326  communicating with the water diversion groove  322 . The first side plate  324  and the second side plate  325  can support the cross-flow fan. The bottom of the water diversion groove  322  is inclined downward from the direction of the second side plate  325  to the first side plate  324  for guiding the condensed water to flow in the inclined direction until it is discharged from the water diversion notch  326 . 
     The lower end of the first side plate  324  is provided with a fan installation hole  327  for installing the cross-flow fan. The outer side of the first side plate  324  is further provided with a drainage structure  328 , and the drainage structure  328  is used to guide the water flowing out of the water diversion notch  326  away from the fan installation hole  327 . The cross-flow fan is rotatably connected to the first side plate  324  through the installation hole, and the cross-flow fan rotates relative to the first side plate  324  to form an air flow. The drainage structure  328  can prevent the condensed water from entering the indoor air duct from the fan installation hole  327 . The drainage structure  328  may be two water-stop ribs disposed on the first side plate  324  and located on the upper side of the fan installation hole  327 , the two water-stop ribs are arranged oppositely, and the high ends of the two water-stop ribs are connected. In this way, the condensed water flows down along the water-stop rib, and it is ensured that the condensed water flowing out from the water diversion notch  326  will not flow to the fan installation hole  327  and the axial flow fan. The drainage structure  328  may also be a water-stop rib disposed on the first side plate  324  and connected to the first side wall  322   a.  The upper edge of the water-stop rib is flush with the upper edge of the first side wall  322   a,  and the lower edge of the water-stop rib is located on the side of the fan installation hole  327  close to the indoor heat exchanger  4 . Thereby, the condensed water flowing out from the water diversion notch  326  flows along the extending direction of the water-stop rib to ensure that the condensed water flowing out from the water diversion notch  326  will not flow to the fan installation hole  327  and the axial flow fan. 
     As shown in  FIG. 16 ,  FIG. 20 ,  FIG. 23  and  FIG. 24 , the mobile air conditioner  100  further includes a middle baffle  5  provided in the housing  10  and an indoor heat exchanger  4 . The volute assembly  3  and the indoor heat exchanger  4  are both provided on the middle baffle  5 . The indoor heat exchanger  4  is provided on the middle baffle  5  of the volute assembly  3  at the air inlet, and is provided with a water storage groove  6  and a drainage groove  7  communicating with the water storage groove  6 . The drainage groove  7  is provided below the volute assembly  3 , and is arranged corresponding to the outdoor heat exchanger of the mobile air conditioner  100 . The bottom of the water storage groove  6  is inclined in the direction of the drainage groove  7 , and the indoor heat exchanger  4  is installed in the water storage groove  6 . When the mobile air conditioner  100  blows out, the condensed water can flow into the drainage groove  7  through the water storage groove  6 , and then the condensed water can flow into the outdoor heat exchanger through the drainage groove  7 . By inclining the bottom of the water storage groove  6  toward the drainage groove  7 , when the condensed water flows in the water storage groove  6 , not only can the condensed water be better guided to the drainage groove  7 , but also the flow rate of the condensed water in the water storage groove  6  can be increased, so as to improve the discharge rate of the condensed water. Therefore, the discharge effect of the condensed water in the mobile air conditioner  100  is improved, and the condensed water can be effectively prevented from accumulating in the water storage groove  6 . 
     The indoor heat exchanger  4  may be inclined in a direction close to the volute assembly  3 . The inclined arrangement of the indoor heat exchanger  4  is convenient to cooperate with the bottom of the water storage groove  6 , and the heat exchange area can be increased. 
     The embodiment of the present disclosure also provides a housing  10 . It can be understood that the housing  10  can be applied to a mobile air conditioner. The specific structure of the housing  10  will be mainly described below.

The housing body  1  can also be made of other alloy materials, or a mixture of metal materials and plastics, as long as the stability of the housing body  1  can be better improved. In this way, it is more beneficial to improve the installation stability of the housing body  1 , thereby effectively improving the practicability, reliability, and durability of the housing body  1 . 
     In this embodiment, in order to make the appearance of the housing  10  aesthetically appealing and make the overall weight of the housing  10  light, the housing body  1  can be optionally made of plastic material. It can be understood that, in order to further improve the overall structural strength of the housing  10 , by arranging a reinforcing housing  2  in the housing body  1 , the overall strength of the housing  10  can be improved by using the reinforcing housing  2 . Optionally, the reinforcing housing  2  is a sheet metal housing or a rigid plastic housing. In this embodiment, the reinforcing housing  2  can be made of sheet metal material or metal casting. 
     In technical solutions of the present disclosure, the housing  10  is provided with the reinforcing housing  2 .
