  • the structural arrangement of the processing cartridge and protrusion in one embodiment may be to solve the above-mentioned risk.
  • the solutions in one embodiment may be described as the following.
  • FIGS. 18a-21b illustrate the first solution in one embodiment.
  • the protrusion 44d and a force receiving element 45 may be disposed on the processing cartridge; a blocking element 44b and a sliding trench 44c may also be disposed on the protrusion 44d; and the force receiving element 45 may be disposed with an inclined surface 45a, a rotating axle 45b, and a force receiving surface 45c.
  • the rotating axle 45b of the force receiving element 45 may be connected to the sliding trench 44c, and the rotating axle 45b may move up and down in the sliding trench 44c.
  • the force receiving element 45 may rotate around the rotating axle 45b, and the gravity center of the force receiving element 45 may be away from the rotating axle 45b and close to the blocking element 44b (having a clockwise rotation tendency). Therefore, the blocking element 44b may be abutted against the force receiving surface 45c (to prevent the force receiving element 45 from rotating clockwise) and ensure that the force receiving surface 45c may be in a vertical state when the processing cartridge is installed in the electronic image-forming device.
  • the inclined surface 45a on the force receiving element 45 may be disposed at a lower side along its vertical direction; and the force receiving surface 45c may mesh with the spacing element 71 and receive the pushing force from the spacing element 71.
  • the force receiving element 45 When the processing cartridge is installed in the electronic image-forming device along the direction indicated by an arrow in FIG. 18a , the force receiving element 45 may be installed to the right side of the spacing element 71, where the inclined surface 45a may be not in contact with the spacing element 71 at this point; and since the force receiving element 45 is under the action of the blocking element 44b, the force receiving surface 45c may be in a vertical state.
  • the spacing element 71 When the spacing element 71 moves along an arrow direction shown in FIGS. 19a and 19b , the spacing element 71 may be abutted against the inclined surface 45a to make the force receiving element 45 rotate around the rotating axle 45b, and the rotating axle 45b may slide upwardly along the sliding trench 44c, such that the blocking element 44b may be disengaged to be not in contact with the force receiving surface 45c.
  • the spacing element 71 is subjected to the gravity from the force receiving element 45, the force receiving element 45 may not overcome the elastic force of the spring 73 due to the limited weight of the force receiving element 45, such that the spacing element 71 may not rotate downwardly.
  • the spacing element 71 When the spacing element 71 moves to the state shown in FIGS. 20a and 20b , the spacing element 71 may be on the right side of the force receiving element 45, and at this point, the force receiving element may be restored to the state shown in FIGS. 20a and 20b under the action of gravity. At this point, the force receiving surface 45c may be in a vertical state, the rotating axle 45b may be at the lower end in the sliding trench 44c, and the force receiving element 45 may be restored to the initial state.
  • the spacing element 71 When the spacing element 71 moves close to the force receiving element 45 along an arrow shown in FIGS. 21a and 21b and mesh with the force receiving surface 45c, the spacing element 71 may provide a force to the force receiving element 45 to make the force receiving element 45 move to the left. Since the height of the rotating axle 45b along the vertical direction is lower than the height of the uppermost part of the spacing element 71, when the force receiving element 45 receives the force from the spacing element 71, the force receiving element 45 may not rotate counterclockwise around the rotating axle 45b as shown in FIGS. 21a and 21b .
  • the rotating axle 45b on the force receiving element 45 may push the sliding trench 44c to make the protrusion 44d move to the left (the rotating axle 45b may rotate relative to the sliding trench 44c). Therefore, the developing unit 41 may rotate clockwise around the rotating axle 46b at this point, thereby moving the developing element 42 away from the photosensitive element 32; and the developing element 42 may rotate from a state which is in contact with the photosensitive element 32 to a state which is not in contact with the photosensitive element 32. Since the force receiving element 45 can rotate around the rotating axle 45b, during the process that the spacing element 71 pushes the force receiving element 45, the force receiving surface 45c may always be in a vertical state, and the force receiving element 45 may not provide a vertical force on the spacing element 71.
  • the first solution in one embodiment may overcome the defects of the existing technology, which may not only make the structure of the processing cartridge simple, but also may not push the spacing element on the electronic image-forming device to move the spacing element downwardly.
  • the force receiving surface of the force receiving element may always maintain a vertical state during the process of receiving the force of the spacing element.
  • FIGS. 22a-25b illustrate the second solution in one embodiment.
  • a protrusion 144d may be disposed with a blocking element 144b and a sliding trench 144c.
  • a force receiving element 145 may be disposed with a bottom surface 145a, a rotating axle 145b, and a force receiving surface 145c.
  • the bottom surface 145a may be disposed at the lower side of the force receiving element 145.
  • the rotating axle 145b may be connected to the sliding trench 144c (in the present solution, the rotating axle 145b may be configured to slide or not slide in the sliding trench 144c), and the force receiving element 145 may rotate around the rotating axle 145b.
  • the force receiving surface 145c may be disposed on one side of the force receiving element 145.
  • the force receiving surface 145c When the processing cartridge is in the state shown in FIGS. 22a and 22b , the force receiving surface 145c may be in a vertical state.
  • the rotating axle 145 may be disposed at the left end of the force receiving element 145, such that the force receiving element 145 may tend to rotate clockwise, and the blocking element 144b may be abutted against the force receiving element 145 to prevent the force receiving element 145 from rotating clockwise.
  • the force receiving surface 145c may not be subject to the force from the outside of the processing cartridge, such that the force receiving surface 145 may be in a vertical state.
  • the rotating axle 145b may be configured to not slide in the sliding trench 144c.
  • the spacing element 171 may be abutted against the bottom surface 145a, and the force receiving element 145 may rotate around the rotating axle 145b to the state shown in FIG. 23a . Since the weight of the force receiving element 145 is relatively small, the force of the force receiving element 145 provided to the spacing element 171 may be less than the elastic force of the spring 173, such that the spacing element 171 may not be pushed downwardly.
  • the rotating axle 145b may be configured to slide in the sliding trench 144c.
  • the spacing element 171 may be abutted against the bottom surface 145a, and the force receiving element 145 may move upwardly under the action of the spacer element 171.
  • the force receiving surface 145c may still maintain a vertical state. Since the weight of the force receiving element 145 is relatively small, the force of the force receiving element 145 provided to the spacing element 171 may be less than the elastic force of the spring 173, such that the spacing element 171 may not be pushed downwardly.
  • the spacing element 171 when the spacing element 171 moves to the left along the direction of an arrow shown in FIGS. 25a and 25b , since the height of the uppermost part of the spacing element 71 along the vertical direction is higher than the height of the rotating axle 145b along the vertical direction, the spacing element 171 may provide a force for the force receiving element 145 when the spacing element 171 is abutted against the force receiving surface 145c. Therefore, the rotating axle 145b on the force receiving element 145 may push the sliding trench 144c, and the rotating axle 145b may rotate relative to the sliding trench 144c.
  • the developing unit 41 may rotate clockwise around the rotating axle 46b, and the developing element 42 may move away from the photosensitive element 32, such that the developing element 42 may rotate from a state which is in contact with the photosensitive element 32 to a state which is not in contact with the photosensitive element 32. Since the force receiving element 145 can rotate around the rotating axle 145b, the force receiving surface 145c may always maintain the vertical state when the spacing element 171 provides a force for the force receiving element 145, and the force receiving element 45 may not provide a vertical force to the spacing element 71.
  • a spacing element 271 may also be disposed with a bump 271a; a force receiving element 245 may also be disposed with a bump 245d, and the distance of the bump 271a on the spacing element extending from the spacing element 271 may be approximately same as the distance of the bump 245d on the force receiving element extending from the force receiving element 245.
  • the bump 271a on the spacing element may be abutted against a plane on the force receiving surface 245c, and the bump 245d on the force receiving element 245 may be abutted against a plane on the spacing element 27, such that when the spacing element 271 provides a force to the force receiving surface 245c, the force receiving surface 245c may always maintain the vertical state.
