[0020] like Figures 1 to 3 As shown, in this embodiment, the present invention includes a processing cartridge body 1, a first conductive element 2, and a second conductive element 3. The processing cartridge body 1 is provided with an end cap 5 and a developing assembly 6. The first conductive element 2 is movably connected to the end cap 5 and can move relative to the processing cartridge body 1. The second conductive element 3 is connected to the developing assembly 6. The first conductive element 2 and the second conductive element 3 abut against each other. When the first conductive element 2 moves away from the processing cartridge body 1, it can be connected to the printing device 7, and when it moves towards the processing cartridge body 1, it separates from the printing device 7.

[0021] The movable electrode includes a first conductive element 2 and a second conductive element 3. The first conductive element 2 is movable relative to the processing cartridge body 1. When the first conductive element 2 moves away from the processing cartridge body 1, the distance between it and the second conductive element 3 gradually increases to achieve contact and conduction between the first conductive element 2 and the printing device 7. When the first conductive element 2 moves closer to the processing cartridge body 1, the distance between it and the second conductive element 3 gradually decreases to achieve separation between the first conductive element 2 and the printing device 7. Compared to the shortcomings of existing technologies, in this invention, when the processing cartridge is not working, the distance between the first conductive element 2 and the second conductive element 3 is minimal, and at this time, the first conductive element 2 is separated from the printing device 7, meaning there is no electrical connection between them. When the processing cartridge is working, the first conductive element 2 moves away from the processing cartridge body 1, gradually increasing the distance between the second conductive element 3 and the first conductive element 2, eventually bringing the first conductive element 2 into contact with the printing device 7 and energizing it. When the first conductive element 2 moves closer to the processing cartridge body 1, the distance between the second conductive element 3 and the first conductive element 2 gradually decreases, thus separating the first conductive element 2 from the printing device 7. Therefore, this invention can prevent the energized components in the printing device from contacting the electrodes when not in operation, further preventing wear and deformation of the energized components in the printing device and unstable operation due to prolonged contact, thereby improving the stability and reliability of the printing operation.

[0022] In some embodiments, the first conductive member 2 moves away from the process cartridge body 1 when the second conductive member 3 rotates a first stroke, and the first conductive member 2 moves towards the process cartridge body 1 when the second conductive member 3 rotates a second stroke after the first stroke. The first stroke is equal to the second stroke. Specifically, when the process cartridge is not working, the distance between the first conductive member 2 and the second conductive member 3 is the smallest, and the first conductive member 2 is separated from the printing device 7, i.e., the two are not in electrical contact. When the process cartridge is working, the second conductive member 3 is driven to rotate a first stroke by the developing assembly 6, so that the distance between the second conductive member 3 and the first conductive member 2 gradually increases, and the first conductive member 2 moves away from the process cartridge body 1 and finally contacts and is powered by the printing device 7. When the second conductive member 3 rotates a second stroke after the first stroke, the distance between the second conductive member 3 and the first conductive member 2 gradually decreases, so that the first conductive member 2 moves towards the process cartridge body 1 and is separated from the printing device 7. It should be noted that the units of the first stroke and the second stroke can be degrees or radians, and both strokes rotate in the same direction, and the first stroke is equal to the second stroke. As shown in Figure 2 , Figures 4 to 5 In some embodiments, the first conductive member 2 is provided with a plurality of first sawteeth 8, and the second conductive member 3 is provided with a plurality of second sawteeth 9. The plurality of first sawteeth 8 can be engaged with the plurality of second sawteeth 9, respectively. The developing assembly 6 includes a developing roller 20 and a developing roller shaft 21. The developing roller shaft 21 is connected to the end of the developing roller 20 and connected to the second conductive member 3. The developing roller 20 is rotationally connected to the process cartridge body 1 and drivingly connected to a coupling. The direction of the first sawteeth 8 is opposite to the direction of the second sawteeth 9. The developing roller 20 can abut against the photosensitive drum to transfer the developer. When the process cartridge is not working, the plurality of first sawteeth 8 on the first conductive member 2 is engaged with the plurality of second sawteeth 9 on the second conductive member 3, so that the electrical contact part 18 of the first conductive member 2 moves towards the process cartridge body 1, and at this time, there is a certain gap between the electrical contact part 18 of the first conductive member 2 and the elastic member 19 of the printing device 7. When the process cartridge is working, the coupling (not shown in the figure) receives the driving force to transmit power to the developing roller 20. Further, the developing roller 20 rotates to drive the second conductive member 3 to rotate, so that the end of the second sawteeth 9 on the second conductive member 3 contacts the end of the first sawteeth 8 on the first conductive member 2, and the electrical contact part 18 of the first conductive member 2 moves away from the process cartridge body 1, and at this time, the electrical contact part 18 of the first conductive member 2 contacts and is powered by the elastic member 19 of the printing device 7. Wherein, when the second conductive member 3 rotates a first stroke, the state of the engagement of the first sawtooth 8 and the second sawtooth 9 changes to the state of the end of the first sawtooth 8 abutting against the end of the second sawtooth 9; when continuing to rotate a second stroke, the state of the end of the first sawtooth 8 abutting against the end of the second sawtooth 9 changes to the state of the engagement of the first sawtooth 8 and the second sawtooth 9, i.e. returns to the initial state.

[0023] In some embodiments, the second conductive member 3 is a ring-shaped member, and the second conductive member 3 is sleeved on the developing assembly 6. Specifically, the second conductive member 3 is sleeved on the developing roller shaft 21.

[0024] As shown in Figures 2 to 6 In some embodiments, the end cover 5 is provided with an elastic extension 10, and the first conductive member 2 is connected to the elastic extension 10; a first elastic member 11 is arranged between the elastic extension 10 and the first conductive member 2, and a second elastic member 14 is arranged between the first conductive member 2 and the processing cartridge body 1, the first elastic member 11 and the second elastic member 14 are respectively arranged on the outer side and the inner side of the first conductive member 2 and are respectively located at the two ends of the first conductive member 2; the end cover 5 is provided with an opening 12, and the elastic extension 10 is located in the opening 12. Wherein, the first elastic member 11 and the second elastic member 14 are both springs. Specifically, by connecting the first conductive member 2 to the elastic extension 10, the first conductive member 2 can move relative to the end cover 5 by the elasticity of the elastic extension 10; in addition, by arranging the first elastic member 11 and the second elastic member 14, the first conductive member 2 can avoid hard contact with the printing device 7 to realize smooth conduction, and the first conductive member 2 can be accurately moved and reset.

[0025] As shown in Figures 3 to 6As shown, in some embodiments, the elastic extension part 10 comprises a first extension part 13 and a second extension part 15, one end of the first extension part 13 is connected to the end cover 5, and the other end is connected with the second extension part 15, the first conductive part 2 is provided with a connecting hole 16, a connecting slot 17 and an electrical contact part 18, the connecting hole 16 and the connecting slot 17 are communicated, the first extension part 13 is fitted in the connecting slot 17, the second extension part 15 is fitted in the connecting hole 16, the first elastic part 11 is connected to the inner side of the second extension part 15 and located in the connecting hole 16, and the electrical contact part 18 can be in conduction with the elastic part 19 of the printing device 7 when the first conductive part 2 moves away from the processing cartridge body 1. Specifically, by fitting the first extension part 13 in the connecting slot 17 and fitting the second extension part 15 in the connecting hole 16, the position of the first conductive part 2 is fixed, and because the elastic extension part 10 itself has elasticity, it can be deformed to a certain extent, so that the first conductive part 2 can move relative to the end cover 5.

[0026] The above description is only the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
