Obviously, the described embodiments are only a preferred embodiment of the present application, but not all the embodiments, and other embodiments obtained by those skilled in the art without creative labor based on the embodiments of the present application all belong to the protection scope of the present application.

[0042] Please refer to Figures 1 to 3 The present application provides a developing cartridge 100, which comprises a developing roller 10, a housing 20, a coupling member 30, a stirring frame 40, a stirring frame gear 50 and a storage member 60.

[0043] The developing roller 10 can rotate around a first axis A1 extending in a first direction.

[0044] The developing roller 10 is a member for carrying a developer in the developing cartridge 100.

[0045] The first direction is the extending direction of the developing roller 10, and the first axis is the rotation axis of the developing roller 10.

[0046] The developing roller body 11 is a main part of the developing roller 10, and the developer is carried on the developing roller body 11.

[0047] The housing 20 can accommodate the developer, and the housing 20 has a first side 21 and a second side 22 disposed apart from the first side 21 in a first direction, the first side 21 having an outer surface 211.

[0048] The housing 20 is a structure having an accommodation cavity, and the accommodation cavity inside the housing 20 can accommodate the developer. The first side 21 and the second side 22 are opposite two sides of the housing 20 disposed apart in the first direction. The outer surface 211 is a surface of the first side 21 facing away from the second side 22.

[0049] The developing roller 10 spans the first side 21 and the second side 22 of the housing 20, one end of the developing roller 10 is provided at the first side 21, and the other end of the developing roller 10 is provided at the second side 22. The developing roller 10 further includes a developing roller gear, and the developing roller gear is provided at the first side 21.

[0050] The coupling member 30 is rotatable about a second axis A2 extending in the first direction, the coupling member 30 is provided at the first side 21 of the housing 20, and the coupling member 30 is disposed apart from the developing roller 10 in a second direction intersecting the first direction, and the coupling member 30 includes a coupling gear 31.

[0051] The coupling member 30 is a member for receiving a driving force of a driving head of the image forming device and transmitting the driving force to the developing roller gear to drive the developing roller 10 to rotate about the first axis.

[0052] The second axis A2 is a rotation axis of the coupling member 30, and the coupling member 30 rotates about the second axis A2 under the driving of the driving head.

[0053] The coupling member 30 is rotationally connected to the first side 21 of the housing 20. Specifically, the coupling member 30 has a rotation portion, the first side 21 of the housing 20 is provided with a bearing portion adapted to the rotation portion, and the coupling member 30 is rotationally connected to the bearing portion of the first side 21 of the housing 20 through the rotation portion.

[0054] As an example, the coupling member 30 has a rotation hole, and the first side 21 of the housing 20 is provided with a protrusion bearing the coupling member 30, and the coupling member 30 is rotationally connected to the protrusion of the first side 21 of the housing 20 through the rotation hole.

[0055] The second direction is a direction intersecting the first direction, and preferably, the second direction is perpendicular to the first direction. In the second direction, the coupling member 30 is disposed apart from the developing roller 10.

[0056] Specifically, the coupling member 30 comprises a coupling gear 31 which is engaged with the developing roller gear. The coupling member 30 receives the driving force of the driving head and rotates the coupling gear 31, which in turn rotates the developing roller gear engaged therewith, thereby rotating the developing roller 10 about the first axis, so that the developer on the developing roller body 11 is transferred to the corresponding photosensitive member to develop the latent electrostatic image on the photosensitive member.

[0057] The stirring frame 40 rotates about the third axis A3 extending in the first direction following the rotation of the coupling member 30, and has a stirring frame shaft 41 extending in the first direction, which is farther from the first axis A1 than the second axis A2 in the second direction.

[0058] The third axis A3 is the rotation axis of the stirring frame 40, and the stirring frame 40 rotates about the third axis A3 following the rotation of the coupling member 30 when the coupling member 30 rotates.

[0059] The stirring frame 40 comprises the stirring frame shaft 41 rotatably connected to the housing 20, and a plurality of stirring blades connected to the stirring frame shaft 41. One end of the stirring frame shaft 41 is rotatably connected to the first side 21 of the housing 20, and the other end of the stirring frame shaft 41 is rotatably connected to the second side 22 of the housing 20. The stirring blades are located in the accommodating cavity of the housing 20, and rotate following the rotation of the stirring frame shaft 41, thereby stirring the developer in the housing 20.

[0060] As shown in Figs. 1 and 2, the stirring frame 40 rotates about the third axis A3 extending in the first direction following the rotation of the coupling member 30, and has a stirring frame shaft 41 extending in the first direction, which is farther from the first axis A1 than the second axis A2 in the second direction. Figure 2 Figure 4 As shown in Figs. 1 and 2, in the second direction, the distance between the stirring frame shaft 41 and the first axis A1 is L1, and the distance between the second axis A2 and the first axis A1 is L3. The distance between the stirring frame shaft 41 and the first axis A1 is greater than the distance between the second axis A2 and the first axis A1, i.e., L1 is greater than L3.

[0061] The stirring frame gear 50 can drive the stirring frame shaft 41 to rotate, and the stirring frame gear 50 is arranged on the first side 21 of the housing 20, which is farther from the first axis A1 than the second axis A2 in the second direction.

[0062] The stirring frame gear 50 is arranged on the first side 21 of the housing 20 at the first side 21, and is fixedly connected to the end of the stirring frame shaft 41 at the first side 21, so that the stirring frame gear 50 rotates synchronously with the stirring frame shaft 41. Specifically, the stirring frame gear 50 is directly engaged with the coupling gear 31, or indirectly engaged with the coupling gear 31 through a plurality of idler gears. When the developing cartridge 100 is in operation, the driving head drives the coupling gear 31 to rotate, and the coupling gear 31 transmits the driving force to the stirring frame gear 50, thereby driving the stirring frame gear 50 to rotate, and the stirring frame gear 50 drives the stirring frame shaft 41 to rotate about the third axis A3. ​

[0063] In the second direction, the developing roller 10, the coupling member 30, and the stirring rack gear 50 are sequentially arranged, the second axis A2 is the rotation axis of the coupling member 30, and the distance between the stirring rack 40 and the developing roller 10 is greater than the distance between the second axis A2 and the developing roller 10.

[0064] The storage member 60 comprises an electrical contact surface 61, which is arranged on the first side 21 of the housing 20 and is arranged separately from the coupling member 30 in the second direction.

[0065] The storage member 60 is used to store the relevant information of the developing cartridge 100, such as the print page information of the developing cartridge 100 and the newness of the developing cartridge 100. The storage member 60 comprises an electrical contact surface 61, which is exposed outside the housing 20 and is oriented transversely to the first direction and the second direction. The electrical contact surface 61 is used to electrically connect with the image forming device, so as to transmit the relevant information of the developing cartridge 100 to the image forming device.

[0066] In the second direction, at least a part of the stirring rack gear 50 is farther from the first axis A1 than the electrical contact surface 61 and the coupling gear 31.

[0067] As an example, as shown in FIG. 1, in the second direction, the entire stirring rack gear 50 is farther from the first axis A1 than the electrical contact surface 61 and the coupling gear 31. Figure 4

[0068] As another example, as shown in FIG. 2, a part of the stirring rack 40 is farther from the first axis A1 than the electrical contact surface 61 and the coupling gear 31. Figure 5 Figure 6

[0069] The developing cartridge 100 provided by the present application is characterized in that, in the second direction, the stirring rack shaft 41 and the stirring rack gear 50 are farther from the first axis A1 than the second axis A2 of the coupling member 30, which can reduce the interference of the vibration generated by the rotation of the stirring rack 40 and the stirring rack gear 50 on the developing roller 10, and help to improve the stability of the developing cartridge 100; in the second direction, the electrical contact surface 61 is arranged separately from the coupling member 30, which can reduce the influence of the vibration on the electrical connection of the storage member 60, and help to improve the stability of the electrical connection of the storage member 60; in the second direction, at least a part of the stirring rack gear 50 is farther from the developing roller 10 than the electrical contact surface 61 and the coupling gear 31, which can further reduce the influence of the stirring rack gear 50 on the developing roller 10, and help to improve the stability of the developing cartridge 100 and the overall developing effect of the image forming device.

[0070] As shown in FIG. 1 and FIG. 2, the developing cartridge 100 comprises a housing 20, a developing roller 10, a coupling member 30, a stirring rack 40, a stirring rack gear 50, and a storage member 60. Figure 1 Figure 4 ​​​​As shown, in some embodiments, the projection of the storage member 60 along the first direction does not coincide with the stirring frame gear 50 .

[0071] The projection of the storage member 60 along the first direction does not fall within the range of the stirring frame 40. In the second direction, the storage member 60 is spaced apart from the stirring frame gear 50, and the vibration generated when the stirring frame 40 rotates has little interference on the storage member 60.

[0072] By adopting the above-mentioned technical solution, the separation between the storage component 60 and the stirring frame gear 50 can effectively reduce the impact of the vibration generated by the movement of the stirring frame gear 50 on the storage component 60, which is helpful for the stability and reliability of the storage component 60; at the same time, it can reduce the interference of the electrical connection of the storage component 60 on the stirring frame gear 50, which helps to improve the uniformity of the developer stirring and improve the development effect.

[0073] like Figure 1 、 Figure 5 and Figure 6 As shown, in some embodiments, at least a portion of a projection of the storage member 60 along the first direction coincides with the stirring frame gear 50 .

[0074] As an example, Figure 5 As shown, a portion of the projection of the storage member 60 along the first direction is located within the range of the stirring frame gear 50 , and another portion is located outside the range of the stirring frame gear 50 . In the second direction, the storage member 60 partially overlaps with the stirring frame gear 50 .

[0075] As another example, Figure 6 As shown, the projection of the storage member 60 along the first direction is entirely located within the range of the stirring frame gear 50 , and in the second direction, the storage member 60 completely overlaps with the stirring frame gear 50 .

[0076] By adopting the above technical solution, at least a portion of the projection of the storage member 60 along the first direction overlaps with the stirring frame gear 50, which can effectively utilize the space of the developing box 100 and make the overall structure of the developing box 100 more compact.

[0077] like Figure 4 and Figure 5 As shown, in some embodiments, the stirring frame shaft 41 is farther from the developing roller 10 than the electrical contact surface 61 and the coupling gear 31 in the second direction.

[0078] Here, the distance between the stirring shaft 41 and the developing roller 10 is set as the distance between the rotation center of the stirring shaft 41 and the rotation center of the developing roller 10, the distance between the electric contact surface 61 and the developing roller 10 is set as the distance between the center of the electric contact surface 61 and the rotation center of the developing roller 10, and the distance between the coupling gear 31 and the developing roller 10 is set as the distance between the rotation center of the coupling gear 31 and the rotation center of the developing roller 10. In practice, the distance between any part on the stirring shaft 41 and any part on the developing roller 10 in rotation can also be taken as the distance between the stirring shaft 41 and the developing roller 10, and the distance between any part on the electric contact surface 61 and any part on the developing roller 10 can also be taken as the distance between the electric contact surface 61 and the developing roller 10, and the distance between any part on the coupling gear 31 and any part on the developing roller 10 can also be taken as the distance between the electric contact surface 61 and the developing roller 10.

[0079] In the second direction, the electric contact surface 61 is located between the coupling gear 31 and the stirring shaft 41, the distance between the stirring shaft 41 and the developing roller 10 is L1, the distance between the electric contact surface 61 and the developing roller 10 is L2, and the distance between the coupling gear 31 and the developing roller 10 is L3. The distance between the stirring shaft 41 and the developing roller 10 is greater than the distance between the electric contact surface 61 and the developing roller 10, that is, L1 is greater than L2, and the distance between the stirring shaft 41 and the developing roller 10 is greater than the distance between the coupling gear 31 and the developing roller 10, that is, L1 is greater than L3.

[0080] By adopting the technical scheme, the stirring shaft 41 is arranged at a position far from the developing roller 10, which can reduce the interference of the vibration generated by the rotation of the stirring shaft 41 on the developing roller 10, and helps to improve the stability of the developing roller 10.

[0081] As shown in FIG. 1, Figure 6 In some embodiments, in the second direction, the electric contact surface 61 is farther from the developing roller 10 than the stirring shaft 41 and the coupling gear 31.

[0082] In the second direction, the stirring shaft 41 is located between the coupling gear 31 and the electric contact surface 61, the distance between the stirring shaft 41 and the developing roller 10 is L1, the distance between the electric contact surface 61 and the developing roller 10 is L2, and the distance between the coupling gear 31 and the developing roller 10 is L3. The distance between the electric contact surface 61 and the developing roller 10 is greater than the distance between the stirring shaft 41 and the developing roller 10, that is, L2 is greater than L1, and the distance between the electric contact surface 61 and the developing roller 10 is greater than the distance between the coupling gear 31 and the developing roller 10, that is, L2 is greater than L3.

[0083] By adopting the technical scheme, the electric contact surface 61 is far away from the developing roller 10, and the electric contact surface 61 is separated from the rotating components on the developing cartridge 100, so that the vibration generated by the movement of the rotating components on the developing cartridge 100 can be reduced to interfere with the electric connection of the electric contact surface 61, and the connection stability of the electric contact surface 61 can be improved.

[0084] As shown in Figures 1 to 3 In some embodiments, the developing roller 10 includes a developing roller body 11 extending in the first direction, and in the first direction, the electric contact surface 61 is farther away from the developing roller body 11 than the first side 21 of the housing 20.

[0085] In the first direction, the electric contact surface 61 and the developing roller body 11 are respectively located on both sides of the first side 21 of the housing 20, and the developing roller body 11, the first side 21 of the housing 20 and the electric contact surface 61 are sequentially arranged.

[0086] By adopting the technical scheme, the electric contact surface 61 is spaced apart from the developing roller body 11 in the first direction, so that the interference of the developing roller body 11 with the electric contact surface 61 when rotating can be reduced, the stability of the developing cartridge 100 can be improved, and the developing effect can be improved.

[0087] In some embodiments, the developing cartridge 100 further includes an electrode 70, and the electrode 70 is located on the second side 22 of the housing 20, and the electrode 70 is electrically connected with components of the developing cartridge 100.

[0088] The electrode 70 is a component electrically connected with a power supply member in the image forming device. The electrode 70 is located on the second side 22 of the housing 20 and is electrically connected with components (for example, at least one of the developing roller 10, the powder feeding roller, and the powder outlet knife) of the developing cartridge 100, and the electrode 70 is used to transmit electricity in the image forming device to the components of the developing cartridge 100 to realize the adsorption and transfer of the developer, and improve the developing effect.

[0089] By adopting the technical scheme, the electrode 70 of the developing cartridge 100 is located on the second side 22 of the housing 20, so that the layout of the developing cartridge 100 space can be optimized, more installation space can be provided for other components, the flexibility of the overall design of the developing cartridge 100 can be improved, and meanwhile, the electrode 70 and the storage member 60 are respectively located on both sides of the housing 20, so that the mutual interference between the electrode 70 and the storage member 60 can be reduced, the stability of the developing cartridge 100 can be improved, and the developing effect can be improved.

[0090] As shown in Figures 2 to 6 In some embodiments, the developing cartridge 100 further includes an intermediate gear 80, and the intermediate gear 80 is arranged on the first side 21 of the housing 20, and the intermediate gear 80 is engaged with the coupling gear 31 and the stirring frame gear 50.

[0091] The intermediate gear 80 is rotatably connected to the first side 21 of the housing 20. The intermediate gear 80 can be one or more. One end of the intermediate gear 80 is engaged with the coupling gear 31, and the other end is engaged with the stirring frame gear 50.

[0092] When the developing cartridge 100 is in operation, the coupling gear 31 receives the driving force from the driving head and rotates, and drives the intermediate gear 80 to rotate, and the intermediate gear 80 transmits the driving force to the stirring frame gear 50, and drives the stirring frame gear 50 to rotate, so that the stirring frame shaft 41 rotates to stir the developer in the housing 20.

[0093] By using the above technical solution, the intermediate gear 80 as a connecting piece can effectively transmit the rotary motion of the coupling gear 31 to the stirring frame gear 50, and drive the stirring frame 40 to rotate following the rotation of the coupling member 30, ensuring uniform stirring during development.

[0094] As shown in FIG. 1, Figures 1 to 3 In some embodiments, the developing cartridge 100 further includes a gear cover 90, which is arranged on the first side 21 of the housing 20, and the storage member 60 is arranged on the gear cover 90.

[0095] The gear cover 90 is detachably connected to the first side 21 of the housing 20, and covers at least a part of each gear of the developing cartridge 100.

[0096] The storage member 60 is detachably connected to the gear cover 90, and the electrical contact surface 61 is exposed outside the gear cover 90.

[0097] By using the above technical solution, the gear cover 90 can protect the internal gears and other components, prevent dust, debris or other external factors from affecting their normal operation, and help improve the reliability of the developing cartridge 100. Combining the storage member 60 with the gear cover 90 helps save space, achieve a more compact design, and improve the overall structural efficiency of the developing cartridge 100.

[0098] In some embodiments, the developing cartridge 100 further includes a holder 62, which is connected to the gear cover 90, and the electrical contact surface 61 is connected to the holder 62. The holder 62 is configured to be fixed relative to the gear cover 90, or the holder 62 is configured to be movable relative to the gear cover 90.
