[0028] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0029] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figures 1 to 4 A counting assembly includes: a housing 10, a driving member 20 and a counting member 30. The driving member 20 is arranged on the housing 10. The driving member 20 is connected to the imaging device. The imaging device drives the driving member 20 to rotate. The counting member 30 is arranged on the housing 10. The counting member 30 is connected to the driving member 20. The driving member 20 drives the counting member 30 to rotate. The counting member 30 includes a power transmission member 31, a mounting shaft 32 and a counting member 33. The power transmission member 31 is arranged on the housing 10 and connected to the driving member 20. The mounting shaft 32 is arranged on the housing 10. The counting member 33 is rotatably mounted on the mounting shaft 32 and connected to the power transmission member 31. The counting member 33 is used to trigger the counting of the counted members.

[0033] In some embodiments of the present invention, the counting member 30 further includes a gear cover 35. The gear cover 35 is disposed on the housing 10. The mounting shaft 32 is disposed on the gear cover 35.

[0034] It is understandable that in some embodiments of the present invention, the mounting shaft 32 may also be provided on the gear cover 35 , thereby reducing the size and complexity of the housing 10 and significantly lowering the production cost of a large component such as the housing 10 .

[0035] Reference Figure 4 and Figure 5 The rotation axis direction of the counting member 30 is the X-axis direction. The axis of the mounting shaft 32 is the A-axis 321. The A-axis 321 has an included angle with the X-axis direction.

[0036] It is understood that by aligning the rotation axis of the counting member 30 with the rotation axis of the power transmission member 31, which also rotates in the X-axis direction, and the A-axis 321 having an inclination angle with the X-axis, the rotation axis of the counting member 33 mounted on the mounting shaft 32 also has an inclination angle with the X-axis. When the counting member 33 is connected to the power transmission member 31, more teeth can engage, improving meshing stability and effectively reducing tooth skipping.

[0037] Reference Figures 7 to 12 A small-diameter gear 311 is provided on the power transmission member 31, and a first-stage gear 331 is provided on the counting member 33. The small-diameter gear 311 is meshed with the first-stage gear 331, and the small-diameter gear 311 and the first-stage gear 331 are helical gears.

[0038] It is understood that in some embodiments of the present invention, the small-diameter gear 311 and the first-stage gear 331 are helical gears, which can maximize the number of teeth that are engaged simultaneously and increase the stability of the transmission.

[0039] It's worth noting that in the embodiments of the present invention, because the overlap coefficient of helical gears is greater than that of spur gears, and because of the helix angle of helical gears, they not only have an end overlap coefficient like spur gears, but also an axial overlap system. This means that when helical gears mesh, more teeth simultaneously engage compared to spur gears, effectively preventing tooth skipping and increasing counting accuracy. Preferably, the helical teeth on the small-diameter gear 311 have an inclination angle of 5° to 10°.

[0040] Reference Figure 10 The small-diameter gear 311 or the first-stage gear 331 is an incomplete gear. A large-diameter gear 312 is provided on the power transmission member 31, and a second-stage gear 332 is provided on the counting member 33. The large-diameter gear 312 is meshed with the second-stage gear 332. The second-stage gear 332 includes at least one tooth. The large-diameter gear 312 cooperates with the second-stage gear 332 to drive the counting member 33 to rotate, so that the meshing of the small-diameter gear 311 and the first-stage gear 331 is disconnected. The counting member 30 also includes a reset elastic member 34. The reset elastic member 34 is connected to the counting member 33. When the meshing of the small-diameter gear 311 and the first-stage gear 331 is disconnected, the reset elastic member 34 drives the counting member 33 to rotate and reset.

[0041] Reference Figure 9 A reset ring 313 is provided on the power transmission member 31, and the reset ring 313 includes a ring wall 313a, a starting surface 313b and an end surface 313c. A reset block 333 is provided on the counting member 33, and one end of the reset elastic member 34 contacts the starting surface 313b, and the other end contacts the reset block 333.

[0042] As will be appreciated, when the imaging device transmits power to the power transmission member 31, the small-diameter gear 311 meshes with the primary gear 331, causing the power transmission member 31 to rotate the counter member 33. Simultaneously, one end of the return spring 34 contacts the starting surface 313b, while the other end contacts the return block 333, thereby storing elastic potential energy.

[0043] The large-diameter gear 312 then meshes with the secondary gear 332, driving the counter 33 to rotate until the small-diameter gear 311 disengages from the primary gear 331. As the power transmission member 31 continues to rotate, the large-diameter gear 312 and the secondary gear 332 also disengage. The reset spring 34 then releases its elastic potential energy, driving the counter 33 to rotate and reset.

[0044] Reference Figures 10 and 11 The counting member 33 is provided with a first trigger block 334 , a second trigger block 335 and a third trigger block 336 , and the first trigger block 334 , the second trigger block 335 and the third trigger block 336 can all trigger the counted member to count.

[0045] It can be understood that in some embodiments of the present invention, as the counting member 33 rotates, the first trigger block 334, the second trigger block 335 and the third trigger block 336 on the counting member 33 contact or disconnect with the counted member in turn, and the service life of the developing box is judged by the length of time and number of times the first trigger block 334, the second trigger block 335 and the third trigger block 336 press the counted member, and the interval between each two presses.

[0046] In some other embodiments of the present invention, a plurality of trigger blocks 337 are provided on the counting member 33 , and each of the trigger blocks 337 can trigger the counted member to perform counting.

[0047] It can be understood that in some embodiments of the present invention, as the counting member 33 rotates, several trigger blocks 337 on the counting member 33 contact or disconnect with the counted member, and the service life of the developing box is judged by the length of time and number of times the several trigger blocks 337 press the counted member, and the length of the interval between each two presses.

[0048] It is worth noting that the outer ring sizes of the first trigger block 334 , the second trigger block 335 and the third trigger block 336 do not exceed the outer diameter of the first-stage gear 331 .

[0049] It can be understood that a developing box according to an embodiment of the present invention includes a counting component according to any embodiment of the first aspect of the present invention.

[0050] It is worth noting that the X-axis direction mentioned in the text is the direction shown by the X-axis of the coordinate system in the accompanying drawings of the specification.

[0051] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
