[0002] As one of the output devices of a computer, a printer is widely used to print the processing results of a computer on relevant media and plays an important role in people's daily lives. And as an important printing consumable, a toner cartridge plays a crucial role in the operation of a printer.

[0003] In existing toner cartridges, most are provided with a toner powder counter, which will be triggered after the toner reaches the consumption amount set by the manufacturer, thereby pausing the printer and prompting the user to replace the toner cartridge or add toner; however, this type of toner cartridge has many problems. First, the toner consumption amount set by the manufacturer is usually less than the actual capacity of the toner in the toner cartridge. Therefore, after the toner powder counter is triggered, there is still residual toner in the toner cartridge that can be used, resulting in waste of resources and affecting the environment. Second, after the user replaces the toner cartridge or adds toner, the user needs to manually adjust to reset the toner powder counter so that the printer can resume working. However, the operation of resetting the toner powder counter is relatively complicated and ordinary users generally cannot master it effectively, bringing many troubles to the user.

[0036] a counting assembly 30, the counting assembly 30 is rotatably arranged in the housing 10, and the counting assembly 30 is connected to the clutch assembly 50;

[0037] a detachment assembly 40, the detachment assembly 40 is arranged in the housing 10;

[0038] When the clutch assembly 50 is engaged with the transmission assembly 20, the transmission assembly 20 drives the clutch assembly 50 to move, and the clutch assembly 50 drives the counting assembly 30 to move;

[0039] When the counting assembly 30 moves to the counting assembly 30 touches the detachment assembly 40, the detachment assembly 40 drives the clutch assembly 50 to separate from the transmission assembly 20, and the counting assembly 30 resets, so that the clutch assembly 50 and the transmission assembly 20 reset and engage.

[0040] Through the above structural arrangement, the counting component and the transmission component are detachably connected, enabling automatic reset of the toner counter of the toner cartridge. During use, the counting component engages with the clutch component, and the counting component moves with the clutch component, and the counter counts the usage amount of toner in the toner cartridge. When the counting component moves to the point where the counting component touches the detachment component, the counting component touches the switch, the printer pauses, the detachment component detaches the clutch component from the transmission component, and the counting component resets to the initial position under the action of the reset device. At the same time, the detachment component resets, the clutch component engages with the transmission component, and the printer resumes work. The structure is simple and convenient to use, effectively realizing the automatic operation and reset of the printer toner cartridge counter, enabling the toner in the toner cartridge to be effectively utilized, preventing waste, improving resource utilization rate, and protecting environmental safety. At the same time, it can also enable the printer to work continuously, bringing convenience to the user, avoiding the complex operation of manually resetting the printer toner cartridge counter, and enhancing the user experience.

[0041] In this embodiment, the detachment component 40 includes a detachment lever 41. A receiving groove 11 is provided on the side wall of the housing 10. The detachment lever 41 is rotatably arranged in the receiving groove 11. The first end of the detachment lever 41 faces the counting component 30, and the second end of the detachment lever 41 faces the clutch component 50. The counting component 30 is provided with a first abutting block 372, and the first abutting block 372 abuts against the first end of the detachment lever 41, so that the second end of the detachment lever 41 abuts against the clutch component 50, thereby driving the clutch component 50 to separate from the transmission component 20. Through the above structural arrangement, the first end of the detachment lever moves under the abutment of the first abutting block, and the second end of the detachment lever abuts against the clutch gear, separating the clutch gear from the clutch chuck. The setting of the lever structure effectively realizes the separation of the two, thereby ensuring that the counting component can be reset and guaranteeing the stability of the product.

[0042] In this embodiment, the first end of the detachment lever 41 is provided with a guiding inclined surface 410. When the counting component 30 moves to the point where the counting component 30 touches the detachment component 40, the first abutting block 372 abuts against the guiding inclined surface 410. Through the above structural arrangement, the setting of the guiding inclined surface enables the first abutting block to gradually abut against the guiding inclined surface, allowing the detachment lever to rotate gradually, and thus enabling the clutch component to be detached from the counting component.

[0043] In this embodiment, the transmission assembly 20 includes a transmission gear 21, a transmission shaft 22, and a clutch chuck 23. The transmission gear 21 is disposed at one end of the transmission shaft 22, and the clutch chuck 23 is disposed at the other end of the transmission shaft 22. The transmission gear 21 meshes with an output gear on the driving device of the printer, and the clutch chuck 23 is detachably connected to the clutch assembly 50. Through the above structure, the transmission gear meshes with the output gear on the driving device of the printer, realizing the synchronous movement of the transmission rod gear and the driving device of the printer. Furthermore, the toner counter of the toner cartridge can estimate the remaining amount of toner in the toner cartridge through the movement of the driving device of the printer, ensuring the continuous progress of the printing work and improving the user experience.

[0044] In this embodiment, the clutch assembly 50 includes a clutch gear 31. The clutch gear 31 is slidably sleeved on the transmission shaft 22. A first transmission block 311 is provided at the bottom of the clutch gear 31, and a second transmission block 231 is provided on the clutch chuck 23. When the first transmission block 311 abuts against the second transmission block 231, the clutch assembly 50 is engaged with the transmission assembly 20. Through the above structure, the abutting setting of the first transmission block and the second transmission block enables the clutch gear to move with the clutch chuck, realizing the engagement of the transmission assembly and the counting assembly. At the same time, the clutch gear can slide on the transmission shaft, enabling the first transmission block and the second transmission block to be detached, realizing the detachment of the transmission assembly and the counting assembly, and further realizing the reset and movement of the counting assembly. The structure is simple and the effect is remarkable.

[0045] In this embodiment, the clutch assembly 50 further includes a return compression spring 32 and a limit block 33. The limit block 33 is disposed at the end of the transmission shaft 22. One end of the return compression spring 32 abuts against the limit block 33, and the other end of the return compression spring 32 abuts against the clutch gear 31. Through the above structure, the setting of the return compression spring can, on the one hand, drive the clutch gear to press tightly against the clutch chuck, so that the first transmission block and the second transmission block are more firmly engaged, ensuring the connection between the transmission assembly and the clutch assembly and enabling the clutch assembly to move stably with the transmission assembly; on the other hand, when the clutch assembly is detached from the transmission assembly, the return compression spring is deformed under force. When the return spring resets, it abuts against the clutch gear, causing the clutch gear to press tightly against the clutch chuck, realizing the reset of the clutch gear. The structure is simple and stable, effectively ensuring the stability of the product.

[0046] In this embodiment, the counting assembly 30 includes a counting gear 34, a return torsion spring 35, and an end cap 36. The end cap 36 is fixedly connected to the housing 10. The counting gear 34 meshes with the clutch gear 31. The end cap 36 and the counting gear 34 form a first accommodation space 60. The return torsion spring 35 is disposed in the first accommodation space 60. One end of the return torsion spring 35 is connected to the end cap 36, and the other end of the return torsion spring 35 is connected to the counting gear 34. Through the above structural arrangement, the return torsion spring can store potential energy and reset the counting gear. When the counting assembly works, the return torsion spring accumulates potential energy as the counting gear moves. When the counting gear moves to a preset position, the detachment assembly detaches the counting gear from the clutch gear, and the return torsion spring resets, driving the counting gear to reset to the initial position. The structure is simple and the effect is stable.

[0047] In this embodiment, the counting assembly 30 further includes a reset chuck 37. The first abutting block 372 is disposed on one side of the reset chuck 37. A second abutting block 371 is provided on the other side of the reset chuck 37. The counting gear 34 is provided with a third abutting block 341. When the counting assembly 30 moves to the position where the counting assembly 30 touches the detachment assembly 40, the third abutting block 341 abuts against the second abutting block 371, and the counting gear 34 drives the reset chuck 37 to rotate. Through the above structural arrangement, the first end of the detachment lever is abutted by the first abutting block and moves. The second end of the detachment lever abuts against the clutch gear, detaching the clutch gear from the clutch chuck. The arrangement of the lever structure effectively realizes the detachment of the two, thereby ensuring that the counting assembly can be reset and guaranteeing the stability of the product.

[0048] In this embodiment, the detachment assembly 40 includes a damping ring 42 and a damping compression spring 43. One side of the damping ring 42 is closely attached to the outer wall of the housing 10. The damping compression spring 43 is disposed between the reset chuck 37 and the housing 10. The damping compression spring 43 is used to press the reset chuck 37 so that the reset chuck 37 is closely attached to the other side of the damping ring 42. Through the above structural arrangement, the setting of the damping ring and the damping compression spring enables the reset chuck to delay the reset, ensuring that the clutch gear and the counting gear can effectively reset to the initial position during the detachment period, improving the stability of the product, and ensuring that the toner counter of the toner cartridge can effectively measure the remaining toner amount, with stable functions.

[0049] In this embodiment, the housing 10 is provided with an arc-shaped groove 12. The reset chuck 37 is provided with a limiting post 374. The limiting post is inserted into the arc-shaped groove 12 and slides in the arc-shaped groove 12. Through the above structural arrangement, the cooperation between the limiting post and the arc-shaped groove enables the reset chuck to rotate in a short range, realizing the detachment and reset of the clutch gear and the counting gear. The structure is simple and the effect is remarkable.
