Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder cartridges, in particular to an integrated toner cartridge with a full-automatic resetting structure. Background Art

[0002] In traditional toner cartridges, when resetting the counting gear, it is often necessary to remove the side cover first, and use a tool to rotate the counting gear to reset it. This resetting method is not user-friendly in operation and may cause damage to other parts of the toner cartridge during operation. Therefore, various related companies are also making corresponding improvements to address the problem.

[0003] The utility model patent with authorization announcement number CN217386142U discloses a resettable toner cartridge and toner cartridge, the toner cartridge comprising a cartridge body and a driving end cover and a conductive end cover respectively arranged at two longitudinal ends of the cartridge body, a driving gear set and a counting gear meshing with the driving gear set are arranged between the cartridge body and the driving end cover, and a conductive member is arranged between the cartridge body and the conductive end cover, characterized in that a notch is provided on a side of the driving end cover close to the counting gear so that at least a portion of the counting gear can be exposed, so that the counting gear can rotate a complete circle in the notch and the driving end cover.

[0004] In the above patent, after the counting gear completes one circle of rotation and becomes stuck, the user can reach into the driving end cover through the notch on the driving end cover and turn the counting gear to reset the counting gear, so that the counting gear can continue to count after the powder is replaced. Although this solves the problem of the complicated steps of removing the end cover for resetting the traditional toner cartridge, the need to manually reset the counting gear still poses a certain operational threshold for the user.

[0005] Therefore, it is imperative to redesign an integrated toner cartridge with a fully automatic resetting structure. Utility Model Content

[0006] In view of the above-mentioned defects of the prior art, the utility model provides an integrated toner cartridge with a fully automatic resetting structure, aiming to solve the problem in the prior art that the toner cartridge needs to be reset manually by turning the counting gear, which is difficult to operate.

[0007] To achieve the above object, the technical solution adopted by the present utility model is: an integrated toner cartridge with a fully automatic reset structure, including a toner cartridge body. A driving gear set is provided at the gear end of the toner cartridge body. A counting gear is meshed on one side of the driving gear set. An elastic structure is arranged on one side of the counting gear. An automatic reset inner top structure that moves back and forth relative to the counting gear is arranged on one side of the gear end. A blocking member and a pressing member are arranged on the mounting shaft of the counting gear. When the automatic reset inner top structure moves to the limit position along the direction of the counting gear under the action of an external force, its inner end is located on the rotation path of the blocking member, and the elastic structure is located on the rotation path of the pressing member. The counting gear is also provided with a dial ring, and there is a notch on the dial ring. The dial ring and the notch are used to sequentially press and release the printer sensing dial during the rotation of the counting gear.

[0008] Based on the above, the beneficial effect of an integrated toner cartridge with a fully automatic reset structure is to solve the problem that in the prior art, it is difficult to manually turn the counting gear to reset the toner cartridge, which is mainly reflected in: by arranging a blocking member and a pressing member on the mounting shaft of the counting gear in the present utility model, during the rotation of the counting gear, the pressing member gradually increases the pressure on the elastic structure until the blocking member rotates to the inner end of the automatic reset inner top structure and is blocked. At this time, the elastic structure accumulates enough reset force. When the toner cartridge is taken out of the drum frame, the automatic reset inner top structure resets, and its inner end also leaves the blocking member immediately. The reset force of the elastic structure is released, and the counting gear is driven to rotate by the pressing member to complete the reset. Therefore, there is no need for the user to manually reset the counting gear, which reduces the operation difficulty and improves the user experience.

[0009] The beneficial effect of the elastic structure is to provide the elastic force required for automatic reset to ensure that the counting gear can automatically return to the initial position after removing the external force; the beneficial effect of the automatic reset inner top structure is to realize the automatic reset of the counting gear of the toner cartridge without user intervention, improving the operation convenience; the beneficial effect of the blocking member is to play a limiting role during the reset process to ensure that the counting gear stops at the correct position; the beneficial effect of the pressing member is to accumulate the energy required for reset by pressing the elastic structure to realize the automatic rotation reset of the counting gear; the beneficial effect of the dial ring and the notch is to accurately control the pressing and release of the printer sensing dial to ensure the normal progress of the toner cartridge recognition process.

[0010] Further, an inner top slide is arranged on one side of the gear end. A spring positioning member is arranged on the gear end between the inner top slide and the counting gear and close to the inner top slide. The automatic reset inner top structure includes a slide seat inner top rod and a reset spring. The slide seat part of the slide seat inner top rod is slidably matched with the inner top slide, and the reset spring is arranged between the slide seat part and the spring positioning member.

[0011] Based on the above, the beneficial effect of the inner top slide is to provide a sliding track for the inner top rod of the slide; the beneficial effect of the spring positioning piece is to ensure that the reset spring is in the appropriate position, providing stable elastic support for automatic reset; the beneficial effect of the inner top rod of the slide is to block the rotation path of the counting gear blocking piece, preventing the counting gear from directly resetting after the recognition is completed; the beneficial effect of the reset spring is to store energy and release it during the reset process, pushing the inner top rod of the slide back to the initial position.

[0012] Furthermore, the counting gear is provided with a toothed ring for meshing with the driving gear set when the counting gear shifts the printer sensing shifter, and the toothed ring is provided with an empty tooth portion for disengaging from the driving gear set after the counting gear completes shifting the printer sensing shifter.

[0013] Based on the above, the beneficial effect of the gear ring is that the counting gear can disengage from the driving gear set after completing a count, thereby avoiding repeated counting; the beneficial effect of the empty tooth portion is that a non-meshing area is provided on the gear ring, thereby ensuring that the counting gear is separated from the driving gear set at a specific position.

[0014] Furthermore, the extrusion member is provided with an extrusion slope surface, and the extrusion slope surface is used to withstand the pressure generated by the elastic structure when the automatic reset inner top structure moves to the extreme position.

[0015] Based on the above, the beneficial effect of the extrusion slope is to increase the contact area between the extrusion component and the elastic structure, and improve the transmission efficiency of the restoring force.

[0016] Furthermore, the gear end is equipped with a gear end cover, the gear end cover is provided with an external interface of a counting gear, the dial ring is equipped with the outside of the external interface of the counting gear, and a buffer groove is also provided on the dial ring. The buffer groove is located on the dial ring, close to the notch, and is used to partially release the printer sensing dial before the dial ring rotates to the notch, thereby reducing the noise generated when the printer sensing dial is fully released at the notch.

[0017] Based on the above, the beneficial effect of the gear end cover is to protect the internal structure and provide an external interface for the counting gear, which is convenient for connection with the printer; the beneficial effect of the external interface of the counting gear is to position the dial ring of the counting gear; the beneficial effect of the buffer groove is to reduce the noise generated when the dial ring rotates to the notch.

[0018] Furthermore, two limiting sliding protrusions are arranged between the counting gear and the inner top slide, and the inner top rod slides through between the two limiting sliding protrusions.

[0019] Based on the above, the beneficial effect of the limiting sliding protrusion is to limit the movement of the push rod in the slide seat except the direction toward the counting gear.

[0020] Further, the elastic structure is a torsion spring.

[0029] An inner top slide 6 is provided on one side of the gear end, and a spring positioning member 7 is provided on the gear end between the inner top slide 6 and the counting gear 3 and close to the inner top slide 6. The automatic reset inner top structure 5 includes a slide seat inner top rod 51 and a reset spring 52. The slide seat portion of the slide seat inner top rod 51 is slidably fitted on the inner top slide 6, and the reset spring 52 is fitted between the slide seat portion and the spring positioning member 7.

[0030] The counting gear 3 is provided with a toothed ring 32, which is used to mesh with the driving gear set 2 when the counting gear 3 turns the printer sensing member. The toothed ring 32 is provided with an empty tooth portion 33, which is used to disengage from the driving gear set 2 after the counting gear 3 completes turning the printer sensing member.

[0031] The extrusion member 312 is provided with an extrusion slope 312a, and the extrusion slope 312a is used to withstand the pressure generated by the elastic structure 4 when the automatic reset inner top structure 5 moves to the limit position.

[0032] The gear end is matched with a gear end cover 8, and the gear end cover 8 is provided with a counting gear external interface 81. The dial ring 34 is matched with the outside of the counting gear external interface 81. The dial ring 34 is also provided with a buffer groove 342. The buffer groove 342 is located on the dial ring 34, close to the notch 341, and is used for partially releasing the printer sensing dial before the dial ring 34 rotates to the notch 341, thereby reducing the noise generated when the printer sensing dial is fully released at the notch 341.

[0035] In summary, the specific implementation of the present utility model is as follows: When the toner cartridge is installed in the drum frame, the automatic reset inner top structure 5 will be pressed by the drum frame along the inner top slide 6 to the counting gear 3. This position is the limit position of the inner pressure of the automatic reset inner top structure 5. When the printer is started, the drive gear set 2 drives the counting gear 3 to rotate. During this process, the dial ring 34 of the counting gear 3 will press the printer sensing dial, and the notch 341 of the dial ring 34 will release the printer sensing dial. After the action, the printer completes the recognition of the toner cartridge;

[0036] During the rotation of the counting gear 3, the extrusion slope 312a on the extrusion member 312 gradually extrudes the elastic structure 4, enabling the elastic structure 4 to store energy. When the counting gear 3 rotates to a preset position, the blocking member 311 rotates to the inner end of the inner top rod 51 of the slide seat of the automatic reset inner top structure 5 and is blocked. At this time, the elastic structure 4 has stored sufficient energy. When the toner cartridge needs to be refilled for reuse, the toner cartridge is taken out of the drum frame. Due to the loss of the extrusion of the drum frame on the automatic reset inner top structure 5, the inner top rod 51 of the slide seat is reset under the action of the return spring 52, and its inner end leaves the blocking member 311. The elastic structure 4 releases energy and drives the counting gear 3 to rotate in the reverse direction to complete the reset action.
