Description

Technical Field

[0001] This utility model relates to the field of electronic imaging equipment, and more particularly to a processing box that can be detachably installed in electronic imaging equipment. Background Technology

[0002] The processing box is detachably installed on the imaging device. Generally, the processing box is provided with a counting component for being actuated by a toggle in the imaging device, thereby enabling the imaging device to identify the processing box. In one type of processing box, the counting component is configured to be movable along the axial direction of the processing box. When the processing box is installed on the imaging device, a part of the counting component moves axially so that it can be actuated by a toggle to achieve the counting function.

[0003] However, the counting component is easily damaged after long-term movement, causing it to become stuck and unable to move, which in turn affects the use of the processing box. Utility Model Content

[0004] This utility model provides a processing box to solve the above-mentioned technical problems. The specific solution is as follows:

[0005] A processing cartridge, detachably mounted to an imaging device equipped with a toggle mechanism, the processing cartridge comprising: a developing housing for containing developer; a developing roller rotatably disposed on the developing housing for carrying developer, having a rotation axis extending in a longitudinal direction; a first end cap disposed at the longitudinal end of the developing housing; and a counting assembly disposed at the longitudinal end of the developing housing, at least a portion of the counting assembly being rotatable about the rotation axis extending in the longitudinal direction to actuate the toggle mechanism to enable the imaging device to identify the processing cartridge, wherein the developing housing, the counting assembly, and the first end cap are arranged sequentially in the longitudinal direction, and at least a portion of the counting assembly protrudes from the first end cap.

[0006] The counting assembly includes a rotating component and a toggle component. The rotating component is rotatably disposed on the developing housing, and the toggle component is disposed on the rotating component and is able to rotate with the rotating component. In the longitudinal direction, at least a portion of the toggle component is further away from the developing housing than the rotating component.

[0007] Along the longitudinal direction, the actuating element protrudes from the first end cap.

[0008] The actuating element includes an actuating part and a connecting part. The actuating part is connected to the connecting part. The actuating part is used to contact / abut against the actuating element. The connecting part is used to connect with the rotating element. In the longitudinal direction, the actuating part is further away from the developing housing than the connecting part.

[0009] At least a portion of the actuating element is elastic.

[0010] The actuating element is configured as a cantilever.

[0011] Along the circumferential direction of the rotating component, the length of the connecting portion is less than the length of the actuating portion.

[0012] The actuating part is designed to be arc-shaped.

[0013] The processing box further includes a driving force receiving and transmitting assembly, which includes a driving force receiver and a driving force transmitting assembly. The driving force receiver is used to receive driving force from the imaging device and drive the developing roller to rotate, as well as the rotating component and the actuating component to rotate.

[0014] The rotating component includes an active part and a non-active part, which are arranged sequentially along the circumferential direction of the rotating component. The active part is used to receive driving force from the driving force transmission assembly to drive the rotating component to rotate, and the non-active part is used to disconnect the driving force transmitted from the driving force transmission assembly so that the rotating component stops rotating.

[0015] The counting component involved in this utility model is designed not to move in the left and right direction, which can avoid wear and even damage to the counting component due to long-term movement, thereby extending the service life of the counting component. In addition, the actuating component is designed to be elastically deformable, which can prevent the actuating component from protruding from the first end cover in the left and right direction and interfering with other components, thereby allowing the developing cartridge to be installed smoothly.

[0021] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0022] The processing cartridge C includes at least a developing cartridge 100, which can be detachably installed into an imaging device equipped with a movable element. For the sake of accuracy and ease of understanding, the developing cartridge 100 is defined as having a front, rear, left, right, upper, and lower position as shown in the figure. The left and right directions are the length direction / longitudinal direction / axial direction of the developing cartridge 100, and the developing cartridge 100 extends along the left and right directions.

[0023] like Figure 1 and Figure 2 As shown, the developing cartridge 100 includes a developing housing 1, a developing roller 21 rotatably disposed on the developing housing 1, a driving force receiving and transmitting assembly 3, and a counting assembly 4. The developing housing 1 is used to contain developer, and the developing roller 21 is used to carry developer and supply it to a photosensitive drum (not shown) outside the developing cartridge 100. The driving force receiving and transmitting assembly 3 is used to receive driving force from the imaging device and transmit the driving force to the developing roller 21 to drive the developing roller 21 to rotate about a first rotation axis L21 parallel to the left-right direction. The driving force receiving and transmitting assembly 3 is also used to transmit the driving force to the counting assembly 4 to drive at least a portion of the counting assembly 4 to rotate about a second rotation axis L4, the second rotation axis L21 being parallel to the first rotation axis L21 / left-right direction. The counting assembly 4 is disposed at the longitudinal end of the developing housing 1 and is used to interact with a propelled component in the imaging device so that the processing cartridge C / developing cartridge 100 can be recognized by the imaging device.

[0024] Furthermore, the driving force receiving and transmitting assembly 3 includes a driving force receiving element 31 and a driving force transmitting assembly 32. Specifically, the driving force receiving element 31 is used to receive driving force from the driving element in the imaging device and transmit the driving force to the driving force transmitting assembly 32. The driving force transmitting assembly 32 includes at least a first transmitting element 321, a second transmitting element 322, and a third transmitting element 323. The first transmitting element 321 is coaxially arranged with the driving force receiving element 31 and can rotate simultaneously with the driving force receiving element 31. It is used to transmit the driving force to the second transmitting element 322 and the third transmitting element 323. The second transmitting element 322 is arranged at the longitudinal end of the developing roller 21 and is used to receive driving force from the first transmitting element 321 to directly or indirectly drive the developing roller 21 to rotate. The third transmitting element 323 is used to receive driving force from the first transmitting element 321 to directly or indirectly drive at least a portion of the counting assembly 4 to rotate.

[0025] In some embodiments, the drive force transmission assembly 32 further includes a fourth transmission member 324 for receiving drive force from the third transmission member 323 and driving at least a portion of the counting assembly 4 to rotate.

[0026] In some embodiments, the third transmission member 323 includes a first transmission part 3231 and a second transmission part 3232. The first transmission part 3231 and the second transmission part 3232 are coaxially arranged and can rotate simultaneously. In the left-right direction, the first transmission part 3231 is located to the left of the second transmission part 3232. The first transmission part 3231 is used to combine with the first transmission member 321 to receive driving force and transmit it to the second transmission part 3232. The second transmission part 3232 is used to transmit driving force to the fourth transmission member 324 to drive at least a portion of the counting assembly 4 to rotate.

[0027] In some embodiments, the fourth transmission member 324 includes a third transmission part 3241 and a fourth transmission part 3242. The third transmission part 3241 and the fourth transmission part 3242 are coaxially arranged and can rotate simultaneously. In the left-right direction, the third transmission part 3241 is located to the right of the fourth transmission part 3242. The third transmission part 3241 is used to combine with the second transmission part 3232 to receive driving force and transmit it to the fourth transmission part 3242. The fourth transmission part 3242 is used to transmit the driving force to the counting component 4 to drive at least a portion of the counting component 4 to rotate.

[0028] In some embodiments, the drive force transmission assembly 32 is configured as a gear assembly, and the first transmission member 321, the second transmission member 322, the third transmission member 323 and the fourth transmission member 324 are configured as gears.

[0029] In some implementations, the drive force transmission component 32 may also be configured as other structures capable of transmitting drive force, such as pulleys, sprockets, etc.

[0030] In some embodiments, the developing cartridge 100 further includes a powder feeder (not shown) and a stirring member (not shown) rotatably disposed on the developing housing 1. The powder feeder contacts the developing housing and is used to supply developer to the developing housing. The stirring member is used to stir the developer contained in the developing housing 1 to prevent developer from clumping and to better transfer the developer to the powder feeder. The driving force transmission assembly 32 also includes a fifth transmission member (not shown), which is disposed at the longitudinal end of the powder feeder to receive driving force from the first transmission member 321 and drive the powder feeder to rotate. A fourth transmission member 324 is disposed at the longitudinal end of the stirring member and is also used to receive driving force from the first transmission member 321 / third transmission member 323 and drive the stirring member to rotate.

[0031] In this embodiment, the driving force receiver 31 is located on the left side of the figure. The end where the driving force receiver 31 is located is the driving end, and the end opposite to the driving end along the left-right direction is the non-driving end / right side.

[0032] The developing cartridge 100 also includes a first end cap 26, which is disposed at the longitudinal end of the developing housing 1. In this embodiment, the first end cap 26 is disposed at the driving end. Along the left-right direction, at least a portion of the first end cap 26 is located to the left of the driving force transmission component 32 / counting component 4. Along the left-right direction, the developing housing 1, the driving force transmission component 32 / counting component 4, and the first end cap 26 are arranged in sequence. Specifically, the first end cap 26 includes a first end cap body 260, a first exposure hole 261 and a second exposure hole 262 disposed in the first end cap body 260. The first exposure hole 261 is used to expose the driving force receiving and transmitting component 3 (e.g., driving force receiving member 31) so that the driving force receiving member 31 can receive driving force from the imaging device. The second exposure hole 262 is used to expose at least a portion of the counting component 4 (e.g., the following actuating member 42) so that the actuating member 42 can interact with the actuated member.

[0033] like Figures 2 to 5 As shown, the counting assembly 4 includes a rotating member 41 and a toggle member 42. The rotating member 41 is rotatably disposed on the developing housing 1, and the toggle member 42 is disposed on the rotating member 41. The toggle member 42 is integrally formed with or separate from the rotating member 41. The rotating member 41 is used to receive driving force from the fourth transmission member 324 / fourth transmission section 3242 and rotate. The toggle member 42 can rotate simultaneously with the rotating member 41. In the left-right direction, the toggle member 42 and the rotating member 41 are arranged sequentially from right to left. That is, in the left-right direction, at least a part of the toggle member 42 is further away from the developing housing 1 than the rotating member 41.

[0034] Furthermore, the rotating member 41 includes an active part 411 and a non-active part 412. The active part 411 and the non-active part 412 are arranged sequentially along the circumferential direction of the rotating member 41. The active part 411 is used to receive driving force from the fourth transmission member 324 to drive the rotating member 41 and the actuating member 42 to rotate, thereby causing the actuating member 42 to actuate the actuated member for counting, thereby enabling the processing cartridge C / developing cartridge 100 to be identified. The non-active part 412 is used to disconnect the driving force transmitted from the fourth transmission member 324 so that the rotating member 41 and the actuating member 42 no longer rotate, thereby causing the actuating member 42 to no longer actuate the actuated member, and the counting is completed.

[0035] Furthermore, the actuating member 42 includes an actuating portion 421 and a connecting portion 422. The actuating portion 421 is connected to the connecting portion 422. The actuating portion 421 is used to contact / abut against the actuating member 42, and the connecting portion 422 is used to connect with the rotating member 41. Preferably, the actuating portion 421 is arc-shaped. Along the left-right direction, the actuating member 42 protrudes from the first end cap 26 in a direction away from the developing housing 1. At least a portion of the actuating member 42 is elastic. Specifically, along the circumferential direction of the rotating member 41, the length of the connecting portion 422 is less than the length of the actuating portion 421. That is to say, the actuating member 42 is equivalent to a cantilever. When the developing cartridge 100 is installed into the imaging device, the actuating member 42 can undergo elastic deformation after contacting other components in the imaging device, thereby avoiding interference between the actuating member 42 and other components in the imaging device, which would prevent the developing cartridge 100 from being installed smoothly.

[0036] In some embodiments, the actuator 42 is made of a resilient material.

[0037] The beneficial effects that can be obtained from this utility model are as follows:

[0038] 1. The counting component 4 is set to not move in the left and right directions, which can avoid wear and even damage to the counting component 4 due to long-term movement, thereby extending the service life of the counting component 4.

[0039] 2. The actuating element 42 is designed to be elastically deformable, which can prevent the actuating element 42 from protruding from the first end cover 26 in the left and right direction and interfering with other components, thereby allowing the developing cartridge 100 to be installed smoothly.
