Technical Field
[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a toner cartridge with a push rod reset structure. Background Art
[0002] In today's printing technology, traditional toner cartridges and drum racks usually require complex maintenance and manual reset processes to achieve the reuse of toner cartridges. For example, the TN1000 / 1035 printer toner cartridge consists of two parts: the drum rack and the toner cartridge. One side of the toner cartridge is equipped with a counting gear structure, which interacts with the drive gear assembly. When the printer is running, the drive gear assembly drives the counting gear structure to rotate, and then presses and releases the sensing element inside the printer through the counting gear structure to complete the "machine recognition" process; thereafter, the empty tooth part of the counting gear structure will rotate to a position that meshes with the drive gear assembly, thereby stopping the counting gear from working. However, when the toner in the toner cartridge is exhausted and the user needs to reload the toner for reuse, the toner cartridge must be manually removed from the drum rack, the gear side cover of the toner cartridge is disassembled, and a tool is used to rotate the counting gear structure so that it can re-engage with the drive gear assembly. This process is not only complicated, but for users who are not familiar with the principles of toner cartridge disassembly and assembly, it may cause damage to the toner cartridge that could have been reused, resulting in a waste of resources.
[0003] Therefore, in order to overcome the above shortcomings, it is imperative to design a toner cartridge with a push rod reset structure. Utility Model Content
[0004] In view of the defects of the above-mentioned prior art, the utility model provides a toner cartridge with a push rod reset structure, aiming to solve the problems of manual resetting of the counting gear when the toner cartridge is reused, the high operation complexity and time cost, and the damage and waste of resources of the reusable toner cartridge caused by the user's unfamiliarity with the disassembly and assembly principles of the toner cartridge.

[0033] The outer surface of the counting gear 3 is provided with an induction gear ring 34, an extended tooth segment 35 and a reset empty tooth segment 36 in counterclockwise order. The reset empty tooth segment 36 is located between the meshing end end of the extended tooth segment 35 and the meshing starting end of the induction gear ring 34. An induction shifter release segment 37 is provided counterclockwise from the meshing end end of the induction gear ring 34 to the meshing starting end. The extended tooth segment 35 and the reset empty tooth segment 36 are both located on the side of the induction shifter release segment 37 close to the gear side cover 2. The reset empty tooth segment 36 is equal to the outer diameter rotation length of the counting gear 3 caused by the elastic member 5 being squeezed into the energy storage groove 33.
[0034] The powder box body 1 is also snap-fitted with an outlet printing assembly positioning plate 7 on one side of the end surface close to the gear side cover 2 , and the gear ends of the powder feeding roller 8 and the developing roller 9 in the powder box body 1 are both positioned and adapted on the outlet printing assembly positioning plate 7 .

[0037] The powder box body 1 is provided with an expansion powder bin 100 .
[0038] The conductive end of the powder box body 1 is provided with a powder adding port 200 .
[0039] The toner cartridge is mounted on a toner cartridge drum frame.
[0040] In summary, the specific implementation of the utility model is as follows: first, the toner cartridge is installed on the toner cartridge drum frame, and the combined structure is placed in the printer. When the printer is started, the driving gear 61 starts to rotate, and the counting gear 3 is driven to rotate through the intermediate gear 65. The induction gear ring 34 first presses the printer induction dial. As the counting gear 3 rotates, the induction gear ring 34 is separated from the printer induction dial, and the induction dial release section 37 reaches the position of the printer induction dial, completing the release action. The counting gear 3 continues to rotate, and the induction gear ring 34 presses the printer induction dial again to complete the machine recognition process.
[0041] After the machine recognition process is completed, the intermediate gear 65 continues to rotate, but due to the existence of the extended tooth segment 35, the counting gear 3 does not stop immediately, but continues to rotate until the reset empty tooth segment 36 is located at the meshing position of the intermediate gear 65, and then the counting gear stops;
[0042] When the counting gear 3 rotates, the elastic member 5 is squeezed by the energy storage groove 33 to store the energy required for resetting. The sliding member 42 in the elastic rod sliding groove 21 on the gear side cover 2 is matched with the convex buckle 32 on the mounting shaft 31 of the counting gear 3 through the hooking part of the elastic hook rod 41, thereby blocking the counting gear 3 from continuing to rotate after the recognition is completed, thereby preventing the counting gear 3 from resetting during the normal use of the toner cartridge.
[0043] After the toner is used up, the user takes out the combined structure from the printer and manually pushes the sliding member 42. The elastic hook rod 41 squeezes the energy storage groove 33, causing the hook fold of the elastic hook rod 41 to deform in the opposite direction, thereby causing the hook fold to disengage from the convex buckle 32, thereby removing the obstruction to the rotation and reset of the counting gear 3. The elastic member 5 releases the stored energy and pushes the energy storage groove 33 on the mounting shaft 54 to rotate the counting gear 3 until the meshing starting point of the induction gear ring 34 is aligned and meshed with the intermediate gear 65, completing the reset and preparing to refill the toner and proceed to the next machine recognition process.
[0044] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or substitutions made to the present invention by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
