[0027] like Figures 1 to 4 As shown, in this embodiment, the present invention includes a developing unit 1, a photosensitive unit 2, a first end cap 3, and a driving side cap 5. The first end cap 3 is connected to one end of the developing unit 1 and the photosensitive unit 2. The driving side cap 5 is rotatably connected between the developing unit 1 and the first end cap 3 or between the photosensitive unit 2 and the first end cap 3. A first separating member 6 is provided on the driving side cap 5, and a second separating member 7 is provided on the first end cap 3. The first separating member 6 includes a flexible body 8, which has a force-receiving end 9 and an abutment end. 10. The first end cap 3 is provided with an action end that can abut against the abutting end 10. When the abutting end 10 abuts against the action end, the developing unit 1 separates from the photosensitive unit 2. When the force-receiving end 9 is subjected to force, the driving side cover 5 rotates in a first direction. When the driving side cover 5 rotates in the first direction, the developing unit 1 contacts the photosensitive unit 2. When the second separating member 7 is subjected to force, the driving side cover 5 rotates in a second direction. When the driving side cover 5 rotates in the second direction, the developing unit 1 separates from the photosensitive unit 2.

[0028] When the processing box is not in operation, since the abutting end 10 of the first separating member 6 abuts against the working end of the first end cover 3, the driving side cover 5 cannot rotate in the first direction, so that the developing unit 1 and the photosensitive unit 2 can maintain a distance and be separated.

[0029] When the processing box is in working condition, the force-applying component in the printer applies force to the force-receiving end 9 of the first separating member 6. At this time, due to the flexibility of the flexible body 8 of the first separating member 6, it deforms and the contact end 10 can separate from the action end, so that the first separating member 6 drives the drive side cover 5 to rotate in the first direction, and further makes the developing unit 1 contact the photosensitive unit 2 when the drive side cover 5 rotates in the first direction.

[0030] When the processing cartridge finishes its working state, the force-applying component in the printer applies force to the second separating member 7, causing the drive side cover 5 to rotate in the second direction. At this time, the developing unit 1 separates from the photosensitive unit 2 when the drive side cover 5 rotates in the second direction. At the same time, due to the flexibility of the flexible body 8 of the first separating member 6, it returns to its initial state, and the abutting end 10 abuts against the acting end again, so that the developing unit 1 and the photosensitive unit 2 can maintain a distance and separate.

[0031] In contrast to the shortcomings of existing technologies, in this invention, the abutting end 10 of the first separating member 6 abuts against the functional end of the first end cover 3 to prevent the developing unit 1 and the photosensitive unit 2 from contacting each other when not in operation. By applying force to the force-receiving end 9 of the first separating member 6, the flexible body 8 of the first separating member 6 is deformed, causing the drive side cover 5 to rotate in the first direction. At this time, the developing unit 1 and the photosensitive unit 2 come into contact, allowing the processing cartridge to work normally. By applying force to the second separating member 7 to drive the drive side cover 5 to rotate in the second direction, the developing unit 1 and the photosensitive unit 2 are separated, and the first separating member 6 can return to its initial state. Therefore, through the arrangement of the first separating member 6 and the second separating member 7, this invention can keep the developing unit 1 in contact with the photosensitive unit 2 in the working state and separate the developing unit 1 from the photosensitive unit 2 in the non-working state, thus avoiding contamination of the photosensitive unit 2 and deformation of the developing unit 1, extending the service life of the processing cartridge, and giving this invention the advantage of being able to separate the photosensitive unit and the developing unit.

[0032] In this embodiment, one end of the second separating member 7 is rotatably connected to the first end cover 3, and the other end abuts against the drive side cover 5; the second separating member 7 includes an arc-shaped rotating block 11, the drive side cover 5 is provided with an arc-shaped groove 12, the arc-shaped rotating block 11 abuts against the arc-shaped groove 12, the arc-shaped rotating block 11 is provided with a connecting shaft 13, the connecting shaft 13 is rotatably connected to the first end cover 3, the axis of the arc-shaped rotating block 11 does not coincide with the axis of the connecting shaft 13, the arc-shaped rotating block 11 has a force-bearing surface 15, the arc-shaped rotating block 11 rotates in the arc-shaped groove 12 when the force-bearing surface 15 is subjected to force, and pushes the arc-shaped groove 12 to rotate in the second direction.

[0033] As can be seen from the above, when the processing cartridge is not in operation, the force-applying component in the printer applies force to the force-bearing surface 15 of the second separating member 7, so that the arc-shaped rotating block 11 can rotate relative to the first end cover 3. Since the axis of the arc-shaped rotating block 11 does not coincide with the axis of the connecting shaft 13, when the arc-shaped rotating block 11 rotates in the arc-shaped groove 12, it can push the arc-shaped groove 12 of the drive side cover 5, so that the drive side cover 5 can rotate in the second direction. At this time, the developing unit 1 and the photosensitive unit 2 are separated to avoid the photosensitive unit 2 being contaminated and the developing unit 1 being deformed, thus extending the service life of the processing cartridge. During this process, the flexible body 8 of the first separating member 6 can return to its initial state.

[0034] In this embodiment, the end of the connecting shaft 13 has a first connecting block 16 and a second connecting block 17, with a gap 18 between the first connecting block 16 and the second connecting block 17. A locking block 19 is provided on the first connecting block 16, and a mounting hole 20 is provided on the first end cap 3. The first connecting block 16, the second connecting block 17, and the locking block 19 all pass through the mounting hole 20, and the locking block 19 is engaged with the first end cap 3. The locking block 19 has a guide slope 21. Specifically, during installation, the first connecting block 16, the second connecting block 17, and the locking block 19 all extend through the mounting hole 20, allowing the locking block 19 to extend through the mounting hole 20 and engage with the first end cap 3. The guide slope 21 facilitates the insertion of the locking block 19 into the mounting hole 20.

[0035] In this embodiment, the flexible body 8 includes a connecting portion 26 and a mounting portion 27. The mounting portion 27 is disposed on the connecting portion 26, and the connecting portion 26 is disposed on the drive side cover 5. The force-receiving end 9 is located at the front end and upper end of the mounting portion 27, and the abutting end 10 is located at the rear end of the mounting portion 27. The abutting end 10 separates from the action end when the force-receiving end 9 is subjected to force. The flexible body 8 and the drive side cover 5 are integrally formed. Specifically, when the force-receiving end 9 is subjected to force, both the flexible body 8 and the drive side cover 5 rotate. Due to the flexibility of the flexible body 8, the abutting end 10 will shift downward relative to the action end to separate from the action end.

[0036] In this embodiment, a second end cap 28 is provided at the other end of the developing unit 1 and the photosensitive unit 2.

[0037] In this embodiment, a shield 29 is provided on the first end cap 3, and the shield 29 is correspondingly provided with the second separator 7; an opening 30 is provided on the first end cap 3, and the drive side cover 5 has a rotating part 31, which is rotatably connected in the opening 30. Specifically, the shield 29 is provided on the first end cap 3 to shield the second separator 7, so as to avoid the second separator 7 from being exposed and easily damaged, so that the processing box can work normally.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
