Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a technical field of an electrophotographic apparatus, more particularly, to a cartridge (a toner hopper/a toner cassette, or a cassette) used in an image forming device by means of electrophotography, such as a printer and a copying machine. 
       BACKGROUND 
       [0002]    Generally speaking, a printer cartridge is composed of major components such as a toner hopper, a waste hopper, a photoconductive component, a primary charging roller (PCR), a magnetic roller, a doctor blade, and a wiper blade. The major components form a cartridge by a combination, and are assembled inside the printer for developing images. According to a position of the laser light source relative to the photoconductive (OPC) drum, a cartridge can be divided into a horizontal exposure type and a vertical exposure type. Therefore, a shape design of the cartridge is also divided into two types: an n-shaped type (like a Chinese character “         ”) and a two-wing-shaped type. A laser source of the n-shaped cartridge is exposed horizontally through the middle of the n-shaped area. A laser source of the two-wing-shaped cartridge is vertically exposed downwards through a part between an upper wing and a lower wing of the two-wing-shaped cartridge. 
         [0003]    Existing cartridges, such as those provided by major manufacturers such as HP, Canon, and Samsung, are all designed to be disposable. That is to say, after toners originally loaded in the cartridge are exhausted, the cartridge is directly discarded, therefore, it is necessary for the user to re-purchase a new cartridge. However, although the toners are used up, most other parts of the cartridge can still be used, especially the photoconductive components (such as photoconductive drum). A direct discard causes waste of resources, as well as environmental pollution. 
         [0004]    In the industry, some companies recycle discarded cartridges by refilling toners, and then sell the refilled cartridges, so as to realize a compatible recycle and reuse. In general, a cartridge can be repeatedly recycled for 3-4 times by refilling. It is difficult for an average user to complete disassembly and assembly of cartridges (also known as cassette, toner hopper, etc.), because disassembly process and assembly process are complicated. Therefore, a hole for replenishing toners is designed in the toner hopper, and a hole for cleaning up wastes is designed in the waste hopper, so as to facilitate recycling companies to re-fill toners, or to facilitate users to fill toners by themselves. However, such toner refilling and cleaning modes are still inconvenient for users. For instance, toners might be spattered or be absorbed by human body. As a result, both the environment and users&#39; bodies will be damaged. 
         [0005]    This problem can be alleviated when most parts of the cartridge reach the service life at the same time. The design of the cartridge is further studied in the industry. Some put forward a design concept of continuous supply toner cartridge. For example, Chinese Patent No. 201220475087.4 proposes a manually filled toner cartridge having one or more identical toner storage bins (vertically stacked) connected to the toner hopper. And a toner filling valve is provided at the bottom of each toner storage bin. According to a metering and detecting device detects consumption of the toner, the user will be reminded to manually open the valve by means of a light signal so as to rapidly fill toners, when it is necessary for the users to fill toners. For another example, Chinese Patent of No. 201220477766.5 puts forward a manually filling toner hopper. One or more identical toner storage bins (vertically stacked) are connected to the toner hopper. And the toner storage bins are connected to the toner hopper. A toner filling valve is provided at the bottom of each toner storage bin. According to a consumption of toners, a metering and detecting device can be used to detect whether it is necessary to fill toners, and to open the toner filling valves, so as to realize automatically refilling. For another example, Chinese Patent of No. 201320642919.1 puts forward a printer toner capacity expansion device, which comprises an expansion bin, a toner hopper and a cartridge seal Mylar. The expansion bin is connected to the toner hopper through a chute opening. And the expansion bin is vertically arranged above the toner hopper. Toners inside the expansion bin are sealed with the cartridge seal Mylar, so as to increase the toner capacity. 
         [0006]    However, the above-mentioned three designs such as automatically filling toner bins (vertically stacked), manually filling toner bins (vertically stacked), or multiple toner capacity expansion bins vertically arranged above the toner hopper, are all conceptual designs. Make a general view at these three solutions, it can be found that: multiple expansion bins for toner hoppers have been designed in the three solutions, however, corresponding expansion bins for waste hoppers have not been designed in the three solutions. In addition, the structure and the capacity of the waste hopper in existing cartridges in the current market cannot meet the requirement to recycle wastes in a continuous toner supplying cartridge. (The existing waste hopper is designed to be located inside the outer cover, so its capacity has to be miniaturized.) It is evidently difficult to satisfy the demand for waste collection. Moreover, parallel arranged designs or vertically stacking designs lead to a new problem, that is, larger internal space of a printer is necessary to solve new problem. Therefore, it is necessary to modify the whole structure of the printer. And for the users, it is not expected to purchase a new machine with an additional cost.

A continuous toner supplying cartridge  100 , comprising a toner hopper  101 , toner storage bins  102 , a waste hopper  103 , a waste storage bin  104 . Wherein, a first isolation mechanism  105  is provided between the toner storage bin  102  and the toner hopper  101 ; and, a second isolation mechanism  106  is provided between the waste storage bin  104  and the waste hopper  103 . 
         [0046]    By using the continuous toner supplying cartridge  100  in the n-shaped structure, multiple toner storage bins and multiple waste storage bins are combined in a single toner cartridge. Because a number of toner containers in the present invention is one or more times greater than a number of toner containers in the prior art, the capacity of toners in the present invention is one or more times larger than the capacity of toners in the prior art. Because a number of waste containers in the present invention is one or more times greater than a number of toner containers in the prior art, the capacity of wastes in the present invention is one or more times larger than the capacity of wastes in the prior art. Toners can be added manually or automatically by being replenished. Waste toners can be removed manually or automatically by being cleaned up. Such an improvement will lead to several times of printing amounts, fully utilize resources, and save users&#39; usage costs. 
         [0047]    The continuous toner supplying cartridge  100  can significantly alleviate waste of resources and environmental pollution caused by existing cartridge which will be directly discarded after being used only once. Meanwhile, the waste storage bins are designed according to a combination of the toner hopper and the toner storage bins. Therefore, the waste hopper can be cleaned by the users, when users add toners. The present invention will extend a useful life of cartridges and reduce printing costs. 
         [0048]    As shown in  FIG. 1  and  FIG. 2 , it can be seen that the continuous toner supplying cartridge  100  comprises a photoconductive (OPC) drum  107 , a magnetic roller  108 , a wiper blade  109 , a primary charging roller (PCR)  110 , a doctor blade  111 , a toner mixer  112 , and an isolating mechanism  130 . This isolating mechanism  130  is used to open the toner hopper  101  when the cartridge  100  is used for the first time. The functions, roles, effects and connection ways of these parts or components are well known to those skilled in the art, therefore, the details related to these issues are unnecessary to be given here. 
         [0049]    The toner hopper  101 , the toner storage bins  102 , and the waste hopper  103  and the waste storage bin  104  are all surrounding the photoconductive (OPC) drum  107 . 
         [0050]    As shown in  FIG. 2 , an approximate position of a printer laser source  113  corresponding to the n-shaped continuous toner supplying cartridge  100  is also marked out in  FIG. 2 . As above mentioned, the laser source  113  is exposed horizontally through the middle of the n-shaped area. 
         [0051]    According to  FIG. 1 , the continuous toner supplying cartridge  100  is configured as an n-shaped structure (like a Chinese character “         ”), and a connection port  114  between the toner storage bins  102  and the toner hopper  101  is located in such a position that: 
         [0052]    The connection port is located above and behind the n-shaped cartridge  100  along a direction in which the cartridge is loaded into a printer, at two outer sides of an included angle θ from both ends of a print width position, which is limited by the cartridge  100  of the printer, to a printer laser source  113  of the printer. 
         [0053]    Furthermore, according to  FIG. 1  and  FIG. 2 , the continuous toner supplying cartridge  100  is configured as an n-shaped structure, and it is preferable that an available space for the toner storage bins  102  is located in such a position that: 
         [0054]    A perpendicular line, which is from the photoconductor (OPC) drum  107 , is vertical to a printer laser source beam  115 ; and then a point is obtained by moving toward the printer laser source  113  by 45 cm from the photoconductor drum  107  along the printer laser source beam  115 ; An upward line is drawn from the point to form an included angle of 60 degrees from the printer laser source beam  113 ; a forward-backward available space of the toner storage bins  102  is a position limited by an overall width of 90 cm, wherein, a left translation is made by 45 cm from the upward line, and a right translation is made by 45 cm from the upward line; and a left-right available space of the toner storage bins  102  is an overall width of the cartridge; wherein, a horizontal line formed by the printer laser source  113  and the photoconductor drum  107  is set as a reference line. 
         [0055]    As shown in  FIG. 2 , reference signs  116  denote a pair of translation lines at an interval of 90 cm, which is the width of the toner storage bins  102 . 
         [0056]    In  FIG. 2 , a reference sign  117  denotes the inclination angle of the toner storage bins  102 , and it uses the horizontal level formed by the printer laser source  113  and the photoconductive drum  107  as a reference line. The value a of the inclination angle of the toner storage bins  102  is in a certain range between 0 degree and 85 degrees, i.e. [0°, 85°]. 
         [0057]    In  FIG. 2 , a reference sign  118  means toners, and a reference sign  119  represents waste toners. 
         [0058]    As shown in  FIG. 2 , the first isolation mechanism  105  provided between the toner storage bins  102  and the toner hopper  101  is movable between a first position in which the toner storage bins  102  is isolated from the toner hopper  101  by the first isolation mechanism  105 , and a second position in which the toner storage bins  102  is connected with the toner hopper  101  by the first isolation mechanism  105 . 
         [0059]    The first isolation mechanism  105  is an openable isolating mechanism. 
         [0060]    In a preferred embodiment, the first isolation mechanism  105  is configured as a switch valve, a seal Mylar, or other isolation mechanisms that can be opened by being actuated from external. Of course, this paragraph is not a limitation. 
         [0061]    As shown in  FIG. 1 , a handle  120  can be preferably provided on the toner storage bin  102  to facilitate the user to replace the entire cartridge  100 . The handle  120  is mounted as a protuberant part or formed on the outer surface of the toner storage bin  102 . 
         [0062]    As shown in  FIG. 1 , a toner filling port  121  can be preferably provided on the toner storage bin  102  so as to facilitate the user to manually or automatically fill the toner storage bin in a traditional manner for considerations such as cost saving. 
         [0063]    In an alternative embodiment, the cartridge  100  includes at least two toner storage bins  102  (four stacked toner storage bins  102  are provided in an embodiment shown in  FIG. 2 ), and a third isolation mechanism  125  is provided between the at least two waste storage bins  102 . The third isolation mechanism  125 , which may employ a same configuration as the first isolation mechanism, is configured as a switch valve, a seal Mylar, or other isolation mechanisms that can be opened by being actuated from external. 
         [0064]    In some embodiments, the toner storage bin(s)  102  is/are assembled on the toner cartridge  100  so as to form an odd shape, along a direction of loading the cartridge  100  into the printer. Wherein the odd shape means that: the way of stacking toner storage bins  102  into the toner cartridge can be freely designed, by taking consideration of the internal space of the printer, in particular to the internal space along the direction of loading the cartridge into the printer (or other image forming devices such as a copying machine). Of course, in case of need, or allowed by the internal space of the printer with some models, a horizontal arrangement or a vertical arrangement can also be made. 
         [0065]    As an alternative solution, a position inside the toner storage bin  102 , which is adjacent to a connection port  104  between the toner storage bin  102  and the toner hopper  101 , is configured as a reverse taper structure or a reverse trapezoidal structure so as to fully guide toners into the toner hopper  101 . 
         [0066]    As shown in  FIG. 1 , as a preferable embodiment, a guiding groove  126  is provided between the toner storage bin(s)  102  and the connection port  104 , so that the toner storage bin(s)  102 , which is/are tilted or inclined under a gravity action of toners in the toner storage bin(s)  102 , can be guided and slipped smoothly into the connection port  114 , so as to be guided into the toner hopper  101 . The guiding groove  126  is connected with the inner space of the toner storage bin(s)  102 , and the guiding groove  126  is connected with the connection port  104 . 
         [0067]    As shown in  FIG. 1  and  FIG. 2 , within the range of the aforementioned available space, the toner storage bin  102  covers various geometrical shapes such as: a square, a rectangle and a circle. 
         [0068]    As shown in  FIG. 1 , the aforementioned the second isolation mechanism is movable  106  between a first position in which the waste storage bin  104  is connected with the waste hopper  103 , and a second position in which the waste storage bin  104  is isolated from the waste hopper  103 . 
         [0069]    The second isolation mechanism  106  is configured as a one-way opening valve which can be opened under an external drive or a gravity action. For instance, a one-way valve driven by an external rotation, or a plastic sheet or a metal sheet, can be provided. Besides, a rotatable separation blade inclining toward the waste hopper  103  can be adopted. 
         [0070]    When it is necessary to be guide waste toners in the waste hopper  103  into the waste storage bin  104 , the second isolation mechanism can be manually opened from outside, or the whole cartridge  100  can be manually rotated upward by 90 degrees, so as to connect the waste storage bin  104  to the waste hopper  103 , and to dump the wastes into the waste storage bin  104  under an automatic guidance of a gravity action. 
         [0071]    In some other embodiments, as shown in  FIG. 3  and  FIG. 4 , waste guiding mechanisms  123 ,  124  can be set in the toner hopper  103 , for guiding waste toners in the toner hopper  103  into the waste storage bin  104 . 
         [0072]    The waste guiding mechanism is configured higher than an edge of the wiper blade  109 , so that the waste toners can be guided to a position higher than the edge of the wiper blade  109 , therefore, the waste toners are guided conveniently. In another word, The connection port between the waste storage bin  104  and the waste hopper  103  is higher than the edge of the wiper blade. 
         [0073]      FIG. 3  and  FIG. 4  illustrate structure diagrams for the waste guiding mechanisms. 
         [0074]    As shown in  FIG. 3 , the reference sign  123  means a belt type guide mechanism which comprises two delivery wheels and a belt surrounding the delivery wheels. The delivery wheels can be driven to rotate by manually rotating a rotary knob provided on the outer surface of the cartridge  100 , so as to guide waste toners into the waste storage bin  104 . 
         [0075]    As illustrated in  FIG. 4 , the reference sign  124  means a blade type guide mechanism which comprises at least one blade. The end(s) of the blade(s) is/are bent near the photoconductor (OPC) drum, so that the blade(s) is/are formed as a L-shaped structure. This blade(s) can be pulled from outside, and the bending at the end(s) can be utilized to guide the waste toners into the waste storage bin  104 . 
         [0076]    In other embodiments, the above-mentioned photoconductor (OPC) drum  107  is configured as the above waste guiding mechanism. At this time, users can manually rotate the cartridge  100  upward by 90 degrees. A thrust generated by the rotation of photoconductor (OPC) drum can pass above the blade and automatically guide waste toners in the toner hopper into the stated waste storage bin. 
         [0077]    In further embodiments, it is particularly preferable that the continuous toner supplying cartridge  100  comprises at least two waste storage bins  104 , and a one-way isolation mechanism, which can be one-way opened, is provided between the at least two waste storage bins  104 . The isolation mechanism is configured such as a one-way valve, a plastic sheet or a metal sheet, to prevent a reverse flow of wastes. 
         [0078]    According to  FIG. 1  and  FIG. 2 , in the process of using this continuous toner supplying cartridge  100 , when toners in the toner hopper  101  are used up or nearly used up, users can open the above-mentioned first isolation mechanism  105 , to automatically guide toners in the toner storage bin  102  into the toner hopper  101  under a gravity action. Hence toners can be continuously supplied. As shown in  FIG. 1 , as a preferable embodiment, the guide groove  126  can guide toners more smoothly. 
         [0079]    As above described, in the structure of continuous toner supplying cartridge  100  with at least two toner storage bins  102 , when toners in the toner hopper  101  are used up or nearly used up, users can open the first isolation mechanism  105 , to automatically guide toners in the first toner storage bin into the toner hopper  101  under a gravity action. Hence toners can be automatically refilled and continuously supplied. Moreover, when toners in the first toner storage bin are used up or nearly used up, users can open the third isolation mechanism between the toner storage bins, so as to automatically guide toners in the second toner storage bin into the toner hopper  101  (by passing the first toner storage bin) under a gravity action. Hence toners are automatically refilled for the second time. The rest can be done in the same manner. In the continuous toner supplying cartridge  100  with more toner storage bins  102 , continuous supply of toners can be realized in the same mode. 
         [0080]    According to  FIG. 1  and  FIG. 2 , in the process of using this continuous toner supplying cartridge  100 , when it is necessary to clean up wastes (for instance, if waste toners accumulated in the waste hopper  103  should be cleaned up, before toners in the toner storage bin  102  is filled to the toner hopper  101 ), users can rotate the cartridge upward by 90 degrees, so as to automatically guide waste toners in the waste hopper  103  into the waste storage bin  104  under gravity action. Besides, a manual mode of external drive (such as the previously mentioned waste guiding mechanisms  123 ,  124  or a rotation thrust of the photoconductor (OPC) drum  107 ) can be adopted, so as to guide waste toners into the waste storage bin  104  and to clean up the waste hopper  103 . 
         [0081]    As above described, in the structure of continuous toner supplying cartridge  100  with at least two waste storage bins  104 , a one-way isolation mechanism is used such as a one-way valve, a plastic sheet or a metal sheet so as to prevent wastes from reversely flowing. In addition, for instance, the cartridge is rotated upward by 90 degrees. Therefore, the wastes can be further guided into an empty waste storage bin, so as to clean up the waste hopper  103 , and to fulfill the requirement of toner recycling under a printing task of continuously supplying toners. Therefore, when toners are automatically refilled from the toner storage bin into the toner hopper, it is not necessary to dump out waste toners. The waste hopper can be cleaned up by directly flipping or simply manually rotating. It is easy to operate. Moreover, the wastes will not be spilled, the environment would not be influenced, and human body would not be damaged. 
         [0082]      FIG. 5  is a structure diagram for another embodiment about the continuous toner supplying cartridge according to present invention. And the continuous toner supplying cartridge in this embodiment has a two-wing-shaped structure.

The functions, roles, effects and connection ways of these parts or components are well known to those skilled in the art, therefore, the details related to these issues are unnecessary to be given here. 
         [0084]    The toner hopper  201 , the toner storage bin  202 , the waste hopper  203  and the waste storage bin  204  are all surrounding the photoconductor (OPC) drum  207 . 
         [0085]    As shown in  FIG. 5 , an approximate position of printer laser source  213  corresponding to the two-wing-shaped continuous toner supplying cartridge  200  is also marked out. As above described, the laser source  213  of the two-wing cartridge is vertically exposed downwards through a part between an upper wing and a lower wing the two-wing cartridge. 
         [0086]    According to  FIG. 5 , the continuous toner supplying cartridge  200  is configured as a two-wing-shaped structure, and a connection port between the toner storage bin  202  and the toner hopper  201  is located in such a position that: 
         [0087]    The connection port is located above and behind the two-wing-shaped cartridge  200  along a direction in which the cartridge is loaded into the printer. 
         [0088]    Further, as can be seen from  FIG. 5 , the continuous toner supplying cartridge  200  is configured as a two-wing-shaped structure, and an available space for the toner storage bin  202  is located in such a position that: 
         [0089]    A perpendicular line, which is from a central point set as a mixer shaft of the toner hopper  201 , is vertical to a laser source beam; an upward line is drawn to form an included angle of 45 degrees from the perpendicular line; a forward-backward available space of the toner storage bin is a position limited by an overall width of 90 cm; wherein, a left translation is made by 45 cm from the upward line and a right translation is made by 45 cm from the upward line; and a left-right available space of the toner storage bin is an overall width of the cartridge. 
         [0090]    In  FIG. 5 , the reference sign  215  means the printer laser beam, and the reference sign  216  represents a pair of translation lines at an interval of 90 cm, which is the width of the toner storage bins  202 . The reference sign  220  means the aforementioned perpendicular line, and the reference sign  221  represents the aforementioned upward line with the included angle of 45 degrees. 
         [0091]    The reference sign  217  means an inclination angle of toner storage bin  202 , and the aforementioned perpendicular line  220  is set as the reference line. The value of the inclination angle of the toner storage bins  202  is in a certain range between 0 degree and 85 degrees, i.e. [0°, 85°]. 
         [0092]    In  FIG. 5 , a reference sign  218  denotes toners, and a reference sign  219  denotes waste toners (wastes). 
         [0093]    The configurations described in the embodiments of  FIG. 1  and  FIG. 2 , can be adopted by the first isolation mechanisms  205  and the second isolation mechanism  206  in the present embodiment. 
         [0094]    In other embodiments, a waste guiding mechanism can also be provided in this two-wing-shaped continuous toner supplying cartridge  200 ; and similarly the configurations described in the embodiments of  FIG. 1  and  FIG. 2  can be adopted for the waste guiding mechanism in the same manner. 
         [0095]    In some other embodiments, this two-wing-shaped continuous toner supplying cartridge  200  can also comprise at least two toner storage bins  202  and at least one waste storage bin  204 , or adopt a design with at least one toner hopper  201  and at least two waste storage bins  204 , so as to expand the toner capacity and the waste capacity of the whole two-wing-shaped continuous toner supplying cartridge  200 . 
         [0096]    On the other hand, this invention proposes an image forming device (image forming device adopting electrophotography such as a printer, a copying machine). It possesses the continuous toner supplying cartridge in any of the above-mentioned embodiments. As above described, when the continuous toner supplying cartridge proposed by the embodiments is adapted to the image forming device such as a printer, a copying machine, it is not necessary to modify the internal structure and boundary dimension of the image forming device such as a printer, a copying machine. An existing installation mode of the image forming device can be directly adopted. 
         [0097]    To sum up, according to the technical features or a combination of the technical features mentioned in the embodiments, the continuous toner supplying cartridge proposed by this invention has the following significant advantages when compared with the prior art: 
         [0000]    1) By assembling multiple toner storage bins and multiple waste storage bins in a single cartridge, a number of toner containers in the continuous toner supplying cartridge in the present invention is one or more times greater than a number of toner containers in the prior art, the capacity of toners in the present invention is one or more times larger than the capacity of toners in the prior art. Because a number of waste containers in the present invention is one or more times greater than a number of toner containers in the prior art, the capacity of wastes in the present invention is one or more times larger than the capacity of wastes in the prior art. Toners can be added manually or automatically by being replenished. Waste toners can be removed manually or automatically by being cleaned up. Such an improvement will lead to several times of printing amounts, fully utilize resources, and save users&#39; usage costs.
 
2) The design of one or more waste storage bins for continuous toner supplying cartridge has fully considered the lifetime of photoconductor (OPC) drum. Generally speaking, the lifetime of photoconductor (OPC) drum can support about 10,000 pages, while the original toners in the existing cartridge can support printing 2,000-2,500 pages only. If the existing cartridge is directly discarded, resources will be seriously wasted and environmental pollution will be caused.
 
3) The design of one or more waste storage bins and one or more toner storage bins for continuous toner supplying cartridge can guarantee using toners with the same model and parameters in all toner storage bins. In this way, the printing quality can be ensured. However, in the existing compatible cartridges, later added toners often react with the residual original toners, which will reduce the printing quality and even result in toner leakage. These problems can be effectively resolved and removed via the continuous toner supplying cartridge proposed in this invention.
 
4) The continuous toner supplying cartridge invented this time has fully considered the inner space of printer, and it is not necessary to change the internal structure of printer. The continuous toner supplying cartridge invented this time can be directly installed and secured along the existing installation direction, and it is not necessary to change or modify other structures or components. Hence the cost can be saved and convenience will be provided in use.
 
5) The continuous toner supplying cartridge invented this time adopts the design of one or more waste storage bins. Moreover, a one-way opened isolation mechanism is provided between the original waste hopper and the waste storage bin. Users can dump wastes in the waste hopper into the waste storage bin(s) via a manual drive. In this way, normal printing can be guaranteed after toners are refilled.
 
6) The continuous toner supplying cartridge designed in this invention has fully considered the service life of photoconductor (OPC) drum and the design of toner storage bin(s). After toners in the whole toner storage bin and the toner hopper are used up, they can be replaced as a whole and it is not necessary to dump the wastes halfway in use.
