Description

Technical Field

[0001] This utility model relates to the field of electronic imaging technology, and in particular to a toner cartridge. Background Technology

[0002] Imaging equipment typically uses removable toner cartridges to supply toner, which develops the electrostatic latent image on the photosensitive element and then transfers it onto a medium such as paper to form a visible image.

[0003] Chinese utility model patent CN108292114B discloses a toner cartridge with a chip holder containing a toner chip and a guide. After installation, closing the cover causes a pusher on the cover to abut against a linkage component, raising the chip holder and allowing the toner chip to connect to electrical contacts in the printer, enabling the printer to identify the toner cartridge model and other information. However, after the toner cartridge is depleted, the remaining toner level and page yield on the chip are reset, necessitating chip replacement. The patent's design involves the toner chip and the printer's chip detection unit moving vertically to mate. This not only presents issues of poor or broken connections due to printer vibration or misoperation during operation but also excessive local pressure. Furthermore, the vertical contact between the chip and the detection unit results in a longer wear path, leading to faster chip contact wear and unstable connection between the chip and the detection unit. Summary of the Invention

[0004] The purpose of this invention is to provide a toner cartridge that ensures the stability of the interface between the toner cartridge chip and the chip detection component.

[0005] To achieve the above-mentioned objectives of this utility model, a toner cartridge is provided, which is detachably installed inside an imaging device. The imaging device contains a chip detection component. The toner cartridge includes a cartridge body, a transmission mechanism, a chip holder, and a toner chip. The cartridge body includes a housing and a first end cap, which is located at one end along the length of the cartridge body. The chip holder is movably mounted on the first end cap, and the toner chip is mounted on the chip holder. The electrical contacts of the toner chip are in electrical contact with the chip detection component along the length of the cartridge. A receiving cavity is formed between the first end cap and the housing, and the transmission mechanism is located within the receiving cavity. The transmission mechanism includes a transmission component. When the toner cartridge is installed into the printing device, the transmission component is subjected to force and drives the chip holder and the toner chip to move closer to the chip detection component along the length of the cartridge as the toner cartridge moves. When the toner cartridge is removed from the printing device, the transmission component forces the chip holder and the toner chip away from the chip detection component as the toner cartridge moves.

[0006] As can be seen from the above, the transmission component can drive the chip holder and toner cartridge chip to move along the length of the toner cartridge and approach the chip detection component, making the contact between the chip and the contact pin more stable. This prevents poor connection or disconnection between the chip and the chip detection component due to vibration or misoperation, ensuring the stability of the electrical connection between the chip and the chip detection component during printing. Horizontal alignment results in more uniform contact pressure between the chip and the chip detection component, effectively reducing wear on the chip contacts caused by excessive local pressure, reducing the friction time between the two during alignment, shortening the wear path, and extending the chip's lifespan.

[0007] A further embodiment includes a first linkage engagement part within the imaging device; the transmission assembly includes a third actuating member and a first elastic member; in the installation direction of the toner cartridge, the first linkage engagement part is located downstream of the third actuating member and can abut against the third actuating member; the chip holder and the third actuating member are slidably engaged in the length direction, the third actuating member and the first end cap are slidably engaged in the installation direction of the toner cartridge, and the chip holder and the first end cap are slidably engaged in the first horizontal direction, which is set at an acute angle to the length direction.

[0008] A further embodiment includes a third actuator with a first linkage, a limiting member, and a chip holder track. The chip holder track extends along its length. The third actuator is connected to the first end cap via a first elastic member, the elasticity of which is parallel to the installation direction of the powder cartridge. The first end cap has a first detection track and a first installation track on its mounting end wall. The first detection track extends along a first horizontal direction, and the first installation track extends along the installation direction. The limiting member is installed in the first installation track and slidably connected to it, with the limiting member and the first installation track having a vertical upper limit engagement. The chip holder has a sliding connection that passes through the first detection track and the chip holder track in sequence. The sliding connection and the first detection track are slidably engaged along their extension direction, and the sliding connection and the chip holder track are also slidably engaged along their extension direction. When the powder cartridge is installed, the first linkage stops moving under the stop action of the first linkage engagement, and the first installation track slides relative to the third actuator. Under the constraint of the first detection track, the first end cap drives the chip holder to move along the first horizontal direction and approach the chip detection member. The first elastic member is in an energy storage state.

[0009] As can be seen from the above, the transmission assembly includes a first actuator, a second actuator, and a third actuator. When installing the toner cartridge, the linkage part of the third actuator moves under the action of the first linkage engagement part of the imaging device. The third actuator drives the chip holder to move along the first horizontal direction, so that the chip docks with the chip detection component. When the door is closed, the drive unit drives the first actuator to drive the second actuator to move. The second actuator drives the stabilizer to move in the vertical direction, thereby ensuring the stability of the toner cartridge chip docking process.

[0010] A further option is to set the first detection track at an angle relative to the installation direction, so that the first detection track gradually moves away from the chip detection component from the end closest to the first linkage part to the end furthest from the first linkage part.

[0011] A further embodiment includes a transmission assembly comprising a first actuating element and a second elastic element. The first actuating element has a second linkage part, and the chip holder has a second linkage engagement part. The chip holder is connected to the first end cap via the second elastic element. A second detection track is provided on the mounting end wall of the first end cap, extending along the length direction. The chip holder has a sliding connection part, which is slidably connected to the second detection track. Before the toner cartridge is installed, the second linkage part and the second linkage engagement part abut against each other along the length direction, and the second elastic element is in a stored state. As the toner cartridge is installed, the second linkage part and the second linkage engagement part separate, and the restoring force of the second elastic element forces the chip holder to approach the chip detection element along the length direction.

[0012] As can be seen from the above, when the door is closed, the drive unit drives the first actuator to move, and the second linkage part on the first actuator separates from the second linkage engagement part. Under the action of the elastic restoring force of the second elastic element, the chip holder moves along the length of the powder box to dock with the chip detection component. The direct contact and engagement between the second linkage part and the second linkage engagement part can effectively save parts and simplify assembly and production processes.

[0013] A further embodiment is that the powder box is also provided with a rotating linkage component, which is located between the second linkage part and the second linkage mating part; the rotating linkage component has a first contact part and a second contact part, the first contact part is closer to the second linkage part relative to the second contact part, and the second linkage part drives the rotating linkage component to rotate through the first contact part; the second contact part is closer to the second linkage mating part relative to the first contact part, and the rotating linkage component drives the second linkage mating part to move through the second contact part.

[0014] As can be seen from the above, the rotating linkage component provides a smooth transition between the second linkage part and the second linkage mating part. When the cover is opened, the first actuating component resets, the second linkage part drives the rotating linkage component to move, and the rotating linkage component drives the second linkage mating part to move. This causes the chip holder to move along the length of the powder box and compress the second elastic element, effectively ensuring the stability of the engagement between the linkage component and the second linkage part. Simultaneously, it effectively reduces design complexity and increases design freedom, thereby improving the stability and smoothness of the engagement between the second linkage part and the second linkage mating part, and reducing wear.

[0015] A further embodiment is that the rotating linkage includes a first wall, a second wall, and a rotating shaft. The rotating shaft is rotatably connected to the housing. Both the first wall and the second wall extend in a direction parallel to the rotating shaft. The first wall and the second wall are set at an angle. The rotating shaft is located at the connection position of the first wall and the second wall.

[0016] A further embodiment includes a stabilizing component in the transmission mechanism; the stabilizing component and the chip holder are spaced apart along the length direction; the transmission assembly drives the stabilizing component to move in the vertical direction, and in the length direction, the stabilizing component and the toner cartridge chip are located on opposite sides of the chip detection component; a stabilizing cavity can be formed between the stabilizing component and the chip holder, and when the toner cartridge chip is electrically connected to the chip detection component, the chip detection component is located in the stabilizing cavity.

[0017] As can be seen from the above, the stabilizer forms a stable cavity when the toner cartridge chip and the detector are connected. The stabilizer can ensure that the detector and the toner cartridge chip remain stable when connected and will not swing left and right. At the same time, it prevents the electrical connection between the chip and the chip detector from becoming unstable due to vibrations generated during printer operation.

[0018] A further solution is to provide a guide slope at the mating end of the stabilizer, with the guide slope tilting downwards from the direction away from the chip holder to the direction close to the chip holder.

[0019] As can be seen from the above, when the stabilizer moves vertically and comes into contact with the chip detection device, the guide ramp allows the stabilizer to move smoothly to the designated position, reducing the risk of collision with the chip detection device.

[0020] A further embodiment includes an elastic reset element in the transmission mechanism; the transmission assembly also includes a second actuator, which drives the stabilizer to move when subjected to force, and the restoring force of the elastic reset element forces the second actuator to reset.

[0021] In summary, the toner cartridge design of this invention effectively improves the stability of the connection with the printer's detection components, extends the lifespan of the chip, and allows users to easily determine whether the toner cartridge is properly seated, while also enhancing the overall performance of the toner cartridge.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0040] First embodiment of powder box See Figures 1 to 6 In this embodiment, the powder cartridge 2 is detachably installed inside the imaging device. The imaging device is equipped with a chip detection component 1 and a driving unit (not shown in the figure). The driving unit is located on the door cover of the imaging device (not shown in the figure).

[0041] The toner cartridge 2 includes a cartridge body 3, a drum frame (not shown in the figure), a chip holder 4, a toner cartridge chip 5, and a transmission mechanism 6. The cartridge body 3 is mounted on the drum frame. The cartridge body 3 includes a housing 30, a first end cap 31, and a second end cap 32. The first end cap 31 and the second end cap 32 are respectively located at both ends of the length direction of the cartridge body 3. The housing 30 and the first end cap 31 form a receiving cavity 33, and the transmission mechanism 6 is located in the receiving cavity 33.

[0042] The first end cap 31 is provided with a vertically extending docking track 34, and the chip holder 4 is slidably connected to the docking track 34. The toner cartridge chip 5 is disposed on the chip holder 4, and the electrical contacts of the toner cartridge chip 5 are electrically connected to the chip detection element 1 along the length of the cartridge body 3. The chip holder 4 is provided with a chip slot 46, and the toner cartridge chip 5 is installed in the chip slot 46 and is limited and engaged with the chip slot 46. The chip holder 4 is provided with a chip removal port 47 communicating with the chip slot 46. The chip removal port 47 is located on the side of the toner cartridge chip 5 away from the electrical contacts, and the chip removal port 47 is exposed outside the first end cap 31.

[0043] Preferably, the chip holder 4 is further provided with a positioning part, and the powder cartridge chip 5 is provided with a positioning mating part 51 that cooperates with the positioning part. The disassembly port of the powder cartridge chip 5 is located on the side wall of the chip holder 4 near the housing 30, and the electrical contacts of the powder cartridge chip 5 face away from the housing 30. In this embodiment, the positioning mating part 51 is a positioning hole. The chip holder 4 is provided with an elastic plate 44, and the positioning part is a positioning protrusion 45 provided on the side of the elastic plate 44 facing the powder cartridge chip 5. The positioning protrusion 45 can be fastened into the positioning hole.

[0044] When the toner cartridge 2 is installed into the printing equipment, the drive unit of the printing equipment drives the transmission mechanism 6 to move. The transmission mechanism 6 drives the chip holder 4 and the toner cartridge chip 5 to move within the docking track 34. The toner cartridge chip 5 is electrically connected to the chip detection component 1.

[0045] Combination Figure 15The transmission mechanism 6 includes a transmission assembly 7 and an elastic reset member 61, which is a spring. The transmission assembly 7 includes a first actuator 70 and a second actuator 71. The second end of the elastic reset member 61 is connected to the first actuator 70, and the first end of the elastic reset member 61 is connected to the housing 30. Optionally, the other end of the elastic reset member 61 can be connected to the first end cover 31. The second actuator 71 is provided with a first slide groove 710 and a second slide groove 711. The first actuator 70 is provided with a first hinge shaft 700 and a limiting slide groove 701. The housing 30 is provided with a limiting hinge shaft 35 on the side facing the first end cover 31. The limiting hinge shaft 35 is slidably connected to the limiting slide groove 701, and the first hinge shaft 700 is slidably connected to the first slide groove 710. The chip holder 4 is provided with a second hinge shaft 40, which is slidably connected to the second slide groove 711.

[0046] With the installation of the toner cartridge 2, the door cover is closed. The drive unit on the door cover drives the first actuator 70 to move, and the elastic reset member 61 stretches and stores elastic potential energy. The first actuator 70 drives the second actuator 71 to move through the first hinge 700, and the second actuator 71 drives the chip holder 4 to move along the docking track 34 through the second hinge 40. When the door cover is opened, the elastic reset member 61 drives the first actuator 70 to reset under the action of the restoring force. The first actuator 70 drives the second actuator 72 to reset, and the second actuator 72 drives the chip holder 4 to reset, thereby moving it away from the chip detection unit 1.

[0047] Second embodiment of powder box 2 See Figures 7 to 11 The difference between this embodiment and the first embodiment of the toner cartridge 2 is that the transmission assembly 7 further includes a stabilizer 8, a third actuating member 72, and a first elastic member 722. When the toner cartridge chip 5 docks with the chip detection member 1, the stabilizer 8 and the chip holder 4 are arranged at intervals along the length direction of the cartridge body 3. In the length direction of the cartridge body 3, the stabilizer 8 and the toner cartridge chip 5 are respectively located on both sides of the chip detection member 1. A stabilizing cavity 80 is formed between the stabilizer 8 and the chip holder 4, and the chip detection member 1 is located in the stabilizing cavity 80. A first linkage engagement part 9 is provided inside the imaging device. In the installation direction of the toner cartridge 2, the first linkage engagement part 9 is located downstream of the third actuating member 71 and can abut against the third actuating member 71.

[0048] With the installation of the powder box 2, the door cover is closed. The first actuator 70 drives the second actuator 71 to move under the action of the door cover's drive part. The second actuator 71 is provided with an ejector part 712. The first end cover 31 is also provided with a stabilizing groove 311. The stabilizing groove 311 extends in the vertical direction. The stabilizing member 8 is disposed in the stabilizing groove 311. The ejector part 712 and the stabilizing member 8 are opposite each other in the vertical direction. The second actuator 71 drives the stabilizing member 8 to move in the stabilizing groove 311 through the ejector part 712.

[0049] Preferably, the mating end of the stabilizer 8 is provided with a guide slope 81, which slopes downward from away from the chip holder 4 to near the chip holder 4.

[0050] The third actuator 72 is provided with a first linkage part 720, a limiting part 721, and a chip track 723, which extends along the length of the box body 3. The third actuator 72 is connected to the first end cover 31 through a first elastic member 722, and the elastic force direction of the first elastic member 722 is parallel to the installation direction of the powder box 2.

[0051] The mounting end wall 310 of the first end cover 31 is provided with a first detection track 312 and a first mounting track 313. The first mounting track 313 extends along the mounting direction of the powder box 2, and the first detection track 312 extends along the first horizontal direction. A limiting member 721 passes through the first mounting track 313 and is slidably connected to the first mounting track. The limiting member 721 and the first mounting track 313 are vertically locked together. The first horizontal direction forms an acute angle with the length direction, and the first horizontal direction is inclined relative to the mounting direction. From the end near the first linkage part 720 to the end away from the first linkage part 720, the first detection track 312 gradually moves away from the chip detection member 1. Preferably, in order to ensure the stability of the movement of the third actuator 72, the number of limiting members 721 is more than two, the number of first mounting rails 313 is also more than two, and one limiting member 721 is slidably connected to the corresponding first mounting rail 313.

[0052] The first mounting track 313 and the first detection track 312 are arranged along the length of the powder box 2, with the first detection track 312 closer to the chip detection element 1 relative to the first mounting track 313. A sliding connection part 41 is provided on the chip holder 4, passing through the first detection track 312 and the chip track 723 in sequence. The sliding connection part 41 and the first detection track 312 are slidably engaged along the extension direction of the first detection track 312. The chip holder 4 is slidably connected to the chip track 723 and the first detection track 312 via the sliding connection part 41. The sliding connection part 41, the first detection track 312, and the chip track 723 cooperate with each other to limit the vertical positioning of the chip holder 4.

[0053] When the toner cartridge 2 is installed into the printer, the first linkage part 720 stops moving under the stop action of the first linkage engagement part 9. However, as the toner cartridge 2 continues to move, the first mounting track 313 continues to slide relative to the third actuator 72. Under the restriction of the first detection track 312, the first end cover 31 drives the chip holder to move along the first horizontal direction and approach the chip detection element 1. At this time, the first elastic element 722 stores elastic potential energy.

[0054] When the door cover is opened and the powder box 2 is taken out, the elastic restoring force of the first elastic element 722 causes the third actuating element 72 to reset. Optionally, the number of sliding connection parts 41 is two or more, and the number of first detection tracks 312 is greater than or equal to the number of sliding connection parts 41.

[0055] Third embodiment of powder box 2 See Figures 12 to 15 The difference between this embodiment and the second embodiment is that there is no need to set a third actuator 72, and there is no need to set a first linkage part 9 on the imaging device. In this embodiment, the first actuator 70 is provided with a second linkage part 702. The first actuator 70 drives the second actuator 71 to move under the action of the driving part, and the second actuator 71 drives the stabilizer 8 to move.

[0056] The mounting end wall 310 of the first end cover 31 is provided with a ribbed track 314 and two second detection tracks 315. Both the ribbed track 314 and the second detection tracks 315 extend along the length of the powder box. The chip holder 4 is provided with a reinforcing rib 42 and two sliding connecting parts 41. The reinforcing rib 42 is located between the two sliding connecting parts 41 and passes through the ribbed track 314, and is slidably connected to the ribbed track 314. The sliding connecting parts 41 pass through the corresponding second detection tracks 315, and each sliding connecting part 41 is slidably connected to the corresponding second detection track 315. The reinforcing rib 42 is provided with a second linkage engagement part 43.

[0057] The transmission assembly 7 also includes a second elastic element 10. The chip holder 4 is connected to the first end cap 31 through the second elastic element 10. The elastic direction of the second elastic element 10 is parallel to the length direction of the powder box. There can be more than two second elastic elements 10. The two second elastic elements 10 are arranged at intervals along the installation direction of the powder box 2.

[0058] When the powder cartridge 2 is in its initial state, the second linkage part 702 and the second linkage engagement part 43 abut against each other along the length direction. At this time, the second elastic member 10 is in a compressed state and stores elastic potential energy. When the door is closed, the drive unit drives the first actuator 70 to move, and the first actuator 70 drives the second actuator 71 to move. At this time, the second linkage part 702 and the second linkage engagement part 43 separate. Under the elastic force of the second elastic member 10, the chip holder 4 moves within the second detection track 315, causing the powder cartridge chip 5 to approach the chip detection member 1 along the length direction and dock with the chip detection member 1.

[0059] When the powder box 2 is removed, the first actuator 70 is reset under the restoring force of the elastic reset member 61, the second linkage part 702 is reset and re-contacts the second linkage engagement part 43, and under the action of the second linkage part 702, the second elastic member 10 is gradually compressed, and the chip holder 4 gradually moves away from the chip detection member 1.

[0060] The second linkage part 702 has an inclined contact surface (not shown in the figure). The contact surface is disposed towards the second linkage engagement part 43 and is inclined in a direction away from the second linkage engagement part 43. The wedge-shaped end facilitates the smooth restoration of contact engagement between the second linkage part 702 and the second linkage engagement part 43 when the door cover is opened and the first actuator 70 is reset, thereby driving the chip holder 4 to move to the initial position.

[0061] Fourth embodiment of powder box 2 See Figure 16 and Figure 17 The difference between this embodiment and the third embodiment is that the second linkage part 702 and the second linkage mating part 43 are indirectly in contact. A rotary linkage member 11 is provided on the powder cartridge 2. The axis of the rotary linkage member 11 extends along a first direction. The rotary linkage member 11 is located between the second linkage part 702 and the second linkage mating part 43. The first contact part 12 is closer to the second linkage part 702 relative to the second contact part 13, and the second contact part 13 is closer to the second linkage mating part 43 relative to the first contact part 12. The rotary linkage member 11 has a first contact part 12 and a second contact part 13. The first contact part 12 can abut against the second linkage part 702, and the second contact part 13 can abut against the second linkage mating part 43. When the door is closed, the drive unit drives the first actuating member 70 to move, causing the second linkage part 702 to separate from the first contact part 12. The chip holder 4 moves along a second direction under the restoring force of the second elastic member 10. The second linkage mating part 43 drives the rotary linkage member 11 to rotate, causing the powder cartridge chip 5 to dock with the chip detection member 1.

[0062] The rotating linkage 11 includes a first wall 110, a second wall 111, and a rotating shaft 112. A first contact portion 12 is located on the first wall 110, and a second contact portion 13 is located on the second wall 111. The rotating shaft 112 is rotatably connected to the first end cover 31. Both the first wall 110 and the second wall 111 extend along an axial direction parallel to the rotating shaft 112. The first wall 110 and the second wall 111 are arranged at an angle. The rotating shaft 112 is located at the connection position of the first wall 110 and the second wall 111.

[0063] Optionally, the second elastic element 10 can be omitted, and the second linkage part 702 can be directly mechanically connected to the rotary linkage part 11, and the rotary linkage part 11 can be directly mechanically connected to the second linkage engagement part 43.

[0064] In summary, the toner cartridge design of this utility model effectively improves the stability of its connection with the printer's detection components, extends the lifespan of the chip, and allows users to easily determine whether the toner cartridge is properly seated, while also enhancing the overall performance of the toner cartridge.
