[0063] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0064] Consumable cartridges, such as toner cartridges, are used to store developer. Typically, these cartridges come in a variety of colors and capacities. To better adapt to printing devices and prevent incorrect installation, cartridges of different capacities and colors need to be labeled to improve installation accuracy.

[0065] In related technologies, the capacity of a consumable box is indicated by installing small parts in different positions. The small parts are fixed to the box body with glue. Production and assembly must consider a series of issues such as the amount of glue, whether the bonding is firm, and whether the toner will fall off. The color of the toner stored in the consumable box is marked by the installation position, which makes the toner box body have poor interchangeability and small parts easy to fall off, bringing inconvenience and hidden dangers to production and assembly.

[0066] The utility model provides a consumables box. Since the consumables information of different box bodies is different, the corresponding identification parts have multiple different structures or positions. The application arranges the information card detachably in the card position part, and the effect of identifying the box body can be achieved by replacing different information cards, thereby improving the versatility of the box body and solving the technical problem of low interchangeability of the box body.

[0067] The consumables box provided by the embodiment of the present utility model is described below with reference to the accompanying drawings.

[0068] refer to Figure 1 and Figure 2 As shown, the utility model provides a consumable box, including: a box body 10 and an information card 20, the box body 10 is used to accommodate the developer and is provided with a clamping portion 11, the information card 20 is detachably arranged in the clamping portion 11, and the side of the information card 20 facing away from the box body 10 has an identification area 21, and the identification area 21 is provided with an identification portion 23 for characterizing the consumable information of the consumable box.

[0069] The positions of the identification parts 23 of the consumable boxes corresponding to different consumable information are different. Since the consumable information of different boxes 10 is different, the corresponding identification parts 23 have multiple different positions or structures.

[0070] The utility model provides a consumables box. Since different box bodies 10 have different consumables information, the corresponding identification part 23 has multiple different positions. The information card 20 is detachably arranged in the card position part 11. The effect of identifying the box body 10 can be achieved by replacing different information cards 20, so that the versatility of the box body 10 is improved, and the technical problem of low interchangeability of the box body 10 is solved.

[0071] refer to Figure 1 and Figure 3 As shown, the locking portion 11 is a groove opened on the outer wall of the box body 10, and the locking portion 11 is recessed into the inner part of the outer wall of the box body 10. In order to improve the aesthetics, when the information card 20 is installed in the locking portion 11, the side of the information card 20 facing away from the box body 10 is flush with the outer wall of the box body 10, ensuring the flatness of the outer wall of the box body 10 and improving the aesthetics of the consumable box.

[0072] In one possible implementation, reference Figure 2 As shown, the identification area 21 includes a capacity identification area 212, in which a first identification portion 231 is provided. The first identification portion 231 is a portion protruding from the surface of the capacity identification area 212. The consumable information represented by the first identification portion 231 includes the consumable box capacity.

[0073] In a possible implementation, the identification unit 23 includes a first identification unit 231, and the first identification unit 231 is located in the capacity identification area 212. Figure 4 and Figure 5 As shown, different consumable box capacities correspond to different positions of the first identification portion 231 .

[0074] In one possible implementation, reference Figure 4 and Figure 5 As shown, the information card 20 is roughly rectangular, and the first identification portion 231 representing different consumable box capacities can be located at different positions in the length direction or width direction of the information card 20, which helps to reduce the error rate of installing the consumable box into the printing device.

[0075] In this example, the first identification portion 231 is arranged at different positions in the length direction or width direction of the information card 20. For example, the position of the first identification portion 231 in the width direction of the information card 20 is fixed, and the different capacities of the box body 10 can be represented according to the position of the first identification portion 231 in the length direction of the information card 20. Figure 4 As shown, in the length direction of the information card 20, the distance between the first identification portion 231 and the color identification area 211 is inconsistent, indicating different capacities of the box body 10; or, referring to Figure 5 As shown, the different capacities of the box body 10 are represented according to the position of the first identification portion 231 in the length direction and the width direction of the information card 20. In the length direction of the information card 20, the distance between the first identification portion 231 and the color identification area 211 is inconsistent, indicating the different capacities of the box body 10.

[0076] In other possible implementations, the information card 20 may also be in a trapezoidal shape, a parallelogram shape, etc.

[0077] The printing device has a matching structure that cooperates with the first identification part 231. The position of the first identification part 231 is different, and the position of the corresponding matching structure is also different. Therefore, through the one-to-one correspondence between the position of the first identification part 231 and the matching structure in the printing device, it can prevent the consumable box with mismatched capacity from being installed in the printing device, reduce the error rate of the consumable box when being installed in the printing device, and ensure the normal use of the printing device.

[0078] In a possible implementation, the first identification portion 231 may be integrally formed on the information card 20 . The first identification portion 231 may be a raised structure in the shape of a cylinder, a rectangular cylinder, or a polygonal cylinder.

[0079] In one possible implementation, reference Figure 2 As shown, the identification area 21 includes a color identification area 211 , in which a second identification portion 232 is provided. The second identification portion 232 is a portion protruding from the surface of the color identification area 211 . The consumables information represented by the second identification portion 232 includes the developer color.

[0080] In one possible implementation, reference Figure 2 As shown, the recognition portion 23 includes a second recognition portion 232 . The second recognition portion 232 is located in the color recognition area 211 . Different positions of the second recognition portion 232 in the color recognition area 211 correspond to different developer colors.

[0081] In a possible implementation, different positions of the second identification portion 232 in the color identification area 211 correspond to different developer colors, and the second identification portion 232 may be a cylindrical protrusion or a rectangular columnar protrusion.

[0082] In one possible implementation, the color identification area 211 and the capacity identification area 212 are arranged at intervals from each other. In this example, the color identification area 211 and the capacity identification area 212 are separated by a dividing line 27. The dividing line 27 is a virtual line. The dividing line 27 can extend along the width direction of the information card 20 or along the diagonal direction of the information card 20.

[0083] In this embodiment, there are multiple, for example four, consumable boxes installed in the printing device, namely a first consumable box, a second consumable box, a third consumable box and a fourth consumable box, wherein the first consumable box is used to accommodate black developer, the second consumable box is used to accommodate magenta developer, the third consumable box is used to accommodate yellow developer, and the fourth consumable box is used to accommodate cyan developer. Therefore, there are multiple information cards 20 corresponding to the multiple consumable boxes, namely a first information card, a second information card, a third information card and a fourth information card.

[0084] In one possible implementation, the second identification portion 232 of each of the four information cards 20, namely the first information card, the second information card, the third information card, and the fourth information card, is fixed in position along the length of the information card 20 and can be positioned in at least two different positions along the width of the information card 20 to indicate different developer contents within the consumable cartridge. Accordingly, the printing device includes a mating structure that interacts with the second identification portion 232. The consumable cartridge can only be installed in the printing device when the position of the second identification portion 232 aligns with the corresponding mating structure. This prevents misinstallation of a consumable cartridge with a mismatched color, reduces the error rate during installation, and ensures normal operation of the printing device.

[0085] In one possible implementation, an identifier 28 is further provided in the color identification area 211. The identifier 28 includes, but is not limited to, at least one of text, letters, and symbols, or a combination of text, letters, and symbols. Of course, the identifier 28 may also be a label affixed to the color identification area 211. By directly observing the identifier 28, the user can determine the color of the developer in the consumable cartridge.

[0086] In one possible implementation, the identifier 28 and the second identification portion 232 are arranged at intervals from each other. The identifier 28 can be arranged on the upper side or the lower side of the second identification portion 232, or on the left side or the right side of the second identification portion 232. The identifier 28 can be, for example, "KC" and "MY". When the identifier 28 is "KC", it means that the information card can be used for a consumable box with a developer of black (Black) or cyan (Cyan). When the identifier is "MY", it means that the information card can be used for a consumable box with a developer of magenta (Magenta) or yellow (Yellow). That is, when two colors are marked on the identifier 28 at the same time, it means that the information card can be used for consumable boxes of two colors of developers, thereby improving the versatility of the information card 20.

[0087] In one possible implementation, the identifier 28 can be, for example, "black", "BK", etc., indicating that the developer in the first consumable box is black developer; the identifier 28 can also be "magenta", "M", etc., indicating that the developer in the second consumable box is magenta developer; the identifier 28 can also be "yellow", "Y", etc., indicating that the developer in the third consumable box is yellow developer; the identifier 28 can also be "cyan", "C", etc., indicating that the developer in the third consumable box is cyan developer, so that the user can know the color of the developer in the consumable box by directly observing the identifier 28.

[0088] The utility model provides a consumable box, in which the information card 20 has a simple structure. The consumable information represented by the identification part 23 located in the color recognition area 211 includes the developer color, and the consumable information represented by the identification part 23 located in the capacity recognition area 212 includes the consumable box capacity. The user can prevent the consumable box from being installed in the wrong position by the different positions of the first recognition part 231 and the second recognition part 232, thereby improving the convenience of using the consumable box.

[0089] The utility model provides a consumables box. According to the different positions of the first identification portion 231 and the second identification portion 232, in this embodiment, there are a total of 8 different information cards 20, which is convenient for flexible selection of the required information card 20 according to usage needs and installation in the card position portion 11.

[0090] In one possible implementation, reference Figure 6 、 Figure 7 and Figure 8As shown, the first engaging portion 12 is disposed within the retaining portion 11, and the information card 20 includes a second engaging portion 22. One of the first engaging portion 12 and the second engaging portion 22 is a protrusion, and the other is a slot. The protrusions extend into the slot and engage with each other. This structure improves the installation stability of the information card 20, reduces the risk of the information card 20 falling off, and makes it easier to disassemble and recycle the information card 20.

[0091] In one possible implementation, the first engaging portion 12 is a engaging groove, and the second engaging portion 22 is a engaging protrusion. The engaging protrusion may be, for example, triangular in shape, and the engaging groove is a rectangular groove. The engaging protrusion extends into the engaging groove and engages with each other, thereby securing the information card 20 in the engaging portion 11.

[0092] In other possible implementations not shown in the figures, the first snap-fitting portion 12 is a snap-fitting protrusion, and the second snap-fitting portion 22 is a snap-fitting groove. The information card 20 is fixed in the snap-fitting portion 11 by extending the snap-fitting protrusion into the snap-fitting groove and snapping them together.

[0093] In one possible implementation, reference Figure 1 and Figure 9 As shown, the information card 20 is slidably disposed within the retaining portion 11. The retaining portion 11 further includes a first guide portion 13 and a second guide portion 25. One of the first guide portion 13 and the second guide portion 25 is a guide groove, and the other is a guide protrusion. The guide protrusion slidably disposed within the guide groove. The interaction of the first guide portion 13 and the second guide portion 25 guides the information card 20 as it slides within the retaining portion 11.

[0094] In one possible implementation, the first guide portion 13 is a guide groove formed on the inner wall of the locking portion 11 , and the second guide portion 25 is a guide protrusion protruding from the side wall of the information card 20 . The guide protrusion slides in the guide groove to enable the information card 20 to slide.

[0095] In other possible implementations not shown in the figures, the first guide portion 13 is a guide protrusion protruding from the inner wall of the locking portion 11, and the second guide portion 25 is a guide groove recessed into the interior of the information card 20. The information card 20 can also slide by sliding the guide protrusion in the guide groove.

[0096] In a possible implementation, the information card 20 is slidably disposed in the latch portion 11 along a first direction. In this example, the first direction refers to Figure 1 The first direction is the width direction of the information card 20 , as indicated by the arrow P in FIG.

[0097] refer to Figure 1 、 Figure 11 and Figure 12 As shown, along the first direction: the first end of the locking portion 11 has a positioning groove 14, the second end of the locking portion 11 has an installation opening 15, and the information card 20 has a positioning protrusion 26 extending into the positioning groove 14 and a stopper 24 abutting against the installation opening 15. In this example, the first guide portion 13 and the second guide portion 25 both extend along the first direction.

[0098] The information card 20 is installed in the locking portion 11 through the installation opening 15. When the information card 20 is installed in the locking portion 11, the information card 20 slides from the installation opening 15 along the first direction until the positioning protrusion 26 extends into the positioning groove 14. The information card 20 is installed in place. At this time, the baffle 24 is blocked by the installation opening 15.

[0099] In one possible implementation, the baffle 24 and the information card 20 may be an integrally formed structure.

[0100] In one possible implementation, the first engaging portion 12 is disposed at an end of the first guide portion 13 away from the positioning groove 14, and the second engaging portion 22 is disposed at an end of the second guide portion 25 away from the positioning protrusion 26. This structure places the first engaging portion 12 closer to the installation opening 15, thereby improving the installation stability of the information card 20 and facilitating the installation and removal of the information card 20.

[0101] In this example, the first engaging portion 12 is a engaging groove provided at the end of the first guide portion 13 away from the positioning groove 14. The second engaging portion 22 is a engaging protrusion, and its position corresponds to that of the first engaging portion 12.

[0102] In one possible implementation, reference Figure 8 and Figure 9 As shown, the second engaging portion 22 is a protruding engaging portion. The side of the second engaging portion 22 that faces the engaging slot is a guiding slope 221. The distance between the guiding slope 221 and the second guide portion 25 gradually increases as the information card 20 is inserted. When the information card 20 is installed in the engaging portion 11, the guiding slope 221 guides the engaging protrusion into the engaging slot, helping it to smoothly engage and connect.

[0103] In this embodiment, the second engaging portion 22 is disposed on the second guiding portion 25 , so that the structure of the information card 20 is simple and compact.

[0104] In one possible implementation, reference Figure 8 and Figure 10As shown, the second guide portion 25 is a guide protrusion, and the side of the second guide portion 25 facing away from the second engaging portion 22 has an inclined surface 251. The inclined surface 251 weakens the strength of the second guide portion 25, allowing the second guide portion 25 to be elastically deformed. This elastic deformation of the second guide portion 25 facilitates removal of the second engaging portion 22 from the first engaging portion 12, thereby reducing the difficulty of removing and replacing the information card 20.

[0105] In one possible implementation, reference Figure 1 and Figure 11 As shown, the inner wall surfaces on both sides of the locking portion 11 are provided with first guide portions 13, referring to Figure 9 and Figure 10 As shown, second guide portions 25 are provided on two opposite side walls of the information card 20 .

[0106] In other possible implementations, the second guide portion 25 may also be provided on the side of the information card 20 facing the box body 10, and the number of the second guide portions 25 may be 1, 2, or 3, etc. The position of the first guide portion 13 corresponds to the position of the second guide portion 25, and the number of the second guide portions 25 is the same.

[0107] The present invention provides a consumables box, wherein the interior of a box body 10 can be used to store "black", "magenta", "yellow" or "cyan" developer. The box body 10 has good versatility and can be produced and processed using the same mold. The difficulty of producing the mold of the box body 10 is reduced and the structure is simpler. The structure of the box body 10 is completely the same. A card portion 11 is reserved on the outer wall of the box body 10. After determining the consumables information of the consumables box, an information card 20 is selected and installed in the card portion 11 of the box body 10. According to the identification area 21 on the information card 20, the consumables information of the consumables box can be obtained.

[0108] The utility model provides a consumables box, the information card 20 can be easily disassembled and replaced, and the information card 20 is no longer fixed by glue, but is fixed by mechanical clamping, which reduces the difficulty of installing the information card 20 and makes the information card 20 more firmly and reliably installed.

[0109] The utility model provides a consumables box. The box body 10 can select a suitable information card 20 for installation according to the different colors of the developer stored inside. By the one-to-one correspondence between the first identification part 231 on the information card 20 and the internal matching structure of the printing device, and the one-to-one correspondence between the second identification part 232 on the information card 20 and the internal matching structure of the printing device, it can prevent the wrong consumables box from being installed in the wrong position of the printing device, thereby reducing the error rate of the consumables box being installed in the printing device.

[0110] The present invention provides a consumables box, which may be a powder box, for example. The box body 10 has an accommodating cavity inside, which is used to accommodate a developer, which may be carbon powder, for example. The consumables box can be used to replenish the developer for the processing box.

[0111] The processing box includes a photosensitive drum and a developing roller arranged on the box body 10, and the consumable box also includes a charging roller arranged on the box body 10. The charging roller is used to uniformly charge the surface of the photosensitive drum, and the developing roller is used to develop the latent image formed on the photosensitive drum with a developer to make it visible.

[0112] The printing device includes a scanner unit that selectively exposes the photosensitive drums based on image information to form a latent image on them. To form an image, each photosensitive drum rotates, and the scanner unit selectively exposes the drums, uniformly charged by a charging roller, to light, forming an electrostatic latent image on the drums. The image is then transferred to a recording medium such as paper through a secondary transfer process.

[0113] During image formation, each photosensitive drum rotates and is selectively exposed to light by a scanner unit after being uniformly charged by a charging roller. This process forms an electrostatic latent image on the photosensitive drum. This latent image is developed by a developing roller, and a toner image of each color is formed on each photosensitive drum.

[0114] The cartridge body 10 includes a receiving chamber and a discharge chamber, which are connected by a delivery channel. A delivery screw is provided within the receiving chamber, and a delivery gear is disposed at the end of the delivery screw. During operation, the delivery gear receives driving force from the printing device and rotates, which drives the delivery screw. The stirring element stirs the developer within the receiving chamber, and the delivery screw transports the developer stored within the receiving chamber through the delivery channel to the discharge chamber. A stirring rod is also provided within the receiving chamber for stirring the developer stored within the receiving chamber.

[0115] In one possible implementation, the consumable box also includes an air pump, which has an air nozzle, which is connected to the discharge chamber. The air pump is used to change the pressure inside the discharge chamber. The box body 10 also has a powder outlet located on one side of the discharge chamber, and the powder outlet is connected to the inside of the discharge chamber. Under the action of the air pump, when the pressure inside the discharge chamber increases, the carbon powder entering the discharge chamber is discharged from the powder outlet.

[0116] In one possible implementation, the air pump includes a threaded pipe fitting that can be compressed or extended. The compression of the threaded pipe fitting reduces the volume inside the air pump, allowing the air pump to supply air to the exhaust chamber. The extension of the threaded pipe fitting increases the volume inside the air pump, allowing the air pump to draw air from the exhaust chamber, thereby changing the air pressure inside the exhaust chamber.
