[0002] This utility model relates to the field of electrophotographic imaging, and particularly to a developing cartridge that can be detachably installed in an electrophotographic imaging device. Background Art

[0003] A developing cartridge is a container that holds a developer. When the developing cartridge is installed in an electrophotographic imaging device (hereinafter referred to as an "imaging device"), using electrostatographic imaging technology, the developer forms an image or text required by the user on the imaging medium. To enable the device to obtain information such as the model of the developing cartridge, a detection device that can interact with a detected part in the device is provided in the existing developing cartridge.

[0004] Generally, one end of the developing cartridge is used to receive driving force and is called the driving end, and the other end is used to receive electricity and is called the conductive end. There is already a developing cartridge in which the detection device is provided at the conductive end, and the conductive end is also called the detection end. The driving force received by the driving end from the imaging device is transmitted to the detection end through a stirring member rotatably provided in the developing cartridge. Thus, the detection device is driven.

[0005] In actual products, the detection device includes multiple components, and the stirring member needs to transmit the driving force from the driving end to the detection end. The load on the stirring member is too large, and it is prone to breakage or deformation during the transmission process. Summary of the Utility Model

[0006] In view of this, the present utility model provides a developing cartridge, which enables the detection device to work properly while reducing the load on the stirring member. Specifically:

[0007] A developing cartridge is detachably installed in an imaging device provided with a detected member. The developing cartridge includes: a housing; a driving force receiving member for receiving driving force from the imaging device; a developing member that can receive the driving force of the driving force receiving member and has a rotation axis parallel to the first direction; a detection device, including a driving component provided at one end of the developing cartridge, an acting component provided at the other end of the developing cartridge, and a transmission member located between the driving component and the acting component. The driving component is used to receive the driving force from the driving force receiving member to drive the transmission member to move, thereby forcing the acting component to interact with the detected member. The transmission member includes a transmission portion provided on the same side as the acting component and a movement portion located between the driving component and the transmission portion. The movement portion includes a plurality of meshing gears. Through the transmission portion, the gears transmit the driving force to the acting component.

[0008] In some embodiments, the developing cartridge further includes a covering member for covering the guiding groove, and the covering member covers the guiding groove from above.

The housing includes an upper housing and a lower housing that are combined with each other. The developing member and the guiding groove are provided on the upper housing. The upper housing and the lower housing are combined by welding in the third direction or the second direction. Both the third direction and the second direction intersect with the first direction, and the third direction also intersects with the second direction. When observed along the first direction, the welding surface formed by welding the upper housing and the lower housing does not coincide with the driving force receiving member.

[0010] In some embodiments, along the third direction, a part of the welding surface is located below the driving force receiving member, or another part of the welding surface is located above the rotation axis of the driving force receiving member, or the welding surface is inclined with respect to the second direction / third direction, or along the second direction, the welding surface is located behind the driving force receiving member.

[0011] In some embodiments, the developing cartridge further includes a left end cap, a right end cap, and a forced pushing portion.

[0016] In some embodiments, the developing cartridge further includes a force receiving member for receiving a separating force from a force applying member in the imaging device. When the developing cartridge is developing, the developing member is in contact with the photosensitive drum outside the developing cartridge. When the developing cartridge is not developing, the force applying member applies a separating force to the force receiving member, and the developing member and the photosensitive drum are separated from each other. The force receiving member is a part of the driving force receiving member.

[0017] In some embodiments, the counting member meshes with one of the gears in the transmission member, and the diameter of the counting member is smaller than the diameter of the gear with which it meshes.

[0018] In some embodiments, the driving member includes a driving force input member and a driving force output portion arranged coaxially.

[0058] It should be understood that the following various embodiments are not isolated from each other, and those skilled in the art can combine the structures of the following various embodiments according to design requirements.

[0059] Example 1

[0060]

Overall structure of the developing cartridge

[0061] AsFigure 1A , Figure 1B and Figure 1C As shown in Figure 1A , Figure 1B and Figure 1C , the developing cartridge 1 includes a housing 2 forming a developer chamber 10 and a rotating member 3 rotatably provided in the housing 2. The rotating member 3 can be, for example, a developing member 31 for delivering the developer outward, or a powder feeding member 32 arranged adjacent to the developing member 31 and delivering the developer to the developing member 31, or a stirring member 33 located in the developer chamber 10. The stirring member 33 stirs the developer in the developer chamber 10, which can prevent the developer from caking on the one hand and deliver the developer to the powder feeding member 32 on the other hand. The developing cartridge further includes a handle 23 connected to the housing 2. The developing member 31 and the handle 23 are respectively located at two ends of the housing 2 along the installation direction.

[0062] The developing member 31 rotates about a first axis L1, and the housing 2 extends in a first direction parallel to the first axis L1. The developing cartridge 1 further has a second direction perpendicular to the first direction and a third direction perpendicular to both the first direction and the second direction. Among them, one end 51 of the first direction points to the left of the developing cartridge, the other end 52 of the first direction points to the right of the developing cartridge, one end 53 of the second direction points to the front of the developing cartridge, the other end 54 of the second direction points to the rear of the developing cartridge, one end 55 of the third direction points to the upper part of the developing cartridge, and the other end 56 of the third direction points to the lower part of the developing cartridge.

[0063] Hereinafter, the left end of the developing cartridge is the driving end, and the right end is the conductive end. The detected member 9 in the device is arranged on the right of the developing cartridge. Therefore, the right end of the developing cartridge can also be called the detection end. The developing cartridge 1 further includes a detection device 6. The detection device 6 has a part located at the driving end, another part located at the detection end, and a part located between the driving end and the detection end. The driving force transmission component 4 is used to transmit the driving force received by the driving force receiving member 41 arranged at the driving end to the rotating member 3 and the detection device 6.

[0064] The housing 2 has a left surface 21 facing the left, a right surface 22 facing the right, and a left end cover 27 and a right end cover 28 respectively combined with the housing 2. Among them, the left end cover 27 is opposite to the left surface 21, and the right end cover 28 is opposite to the right surface 22. A part of the driving force receiving member 41 is exposed outward from the left end cover, and a part of the detection device 6 is exposed outward from the right end cover 28, as Figure 1BAs shown, the right end cap 28 has an exposure port 281, and the size of the exposure port 281 is larger than the size of the component (hereinafter referred to as the acting component 63) of the detection device 6 at the detection end; further, the developing cartridge 1 further includes a developer adjustment member 29 fixedly installed on the housing 2, a conductive member 26 combined with the housing 2, and a chip assembly 11 installed on one of the housing 2, the left end cap 27, and the right end cap 28. The chip assembly 11 can be a chip 7 provided with a substrate, electrical contacts, and a storage portion at the same time, or can be a member having a substrate, electrical contacts, a storage portion, and a movable member that can be movably connected to the electrical contacts. The chip assembly 11 is used to establish a communication connection with the imaging device.

[0065] The conductive member 26 is located at the detection end and includes a main body portion 26a and a power input portion 26b provided on the main body portion 26a. The main body portion 26a or the power input portion 26b is fixedly connected to the housing 2, and the power input portion 26b is used to receive power from the device to supply at least to the developing member 31.

[0066] The developer adjustment member 29 includes a blade holder 291 and a blade 292. The blade holder 291 is fixedly installed on the housing 2, and the blade 292 is fixed on the blade holder 291 and is used to contact the developing member 31 to adjust the thickness of the developer on the surface of the developing member 31; the blade holder 291 includes a first part 2911 and a second part 2912 connected to each other. The blade 292 is fixed on the second part 2912, and a bending portion 2913 is formed between the first part 2911 and the second part 2912, which can enhance the strength of the blade holder 291. As Figure 3G shown, when viewed along the first direction, the bending portion 2913 is located outside the projection range of the driving force receiving member 41, or in other words, the projection of the driving force receiving member 41 does not pass through the bending portion 2913. Such a setting is beneficial to reducing the influence of the vibration generated when the driving force receiving member 41 rotates on the bending portion 2913. Thus, during the developing / working process of the developing cartridge 1, the developer adjustment member 29 can be more stable.

[0067] In some embodiments, along the first direction, the projection of the following intermediate gear 46 also does not pass through the bending portion 2913, which can further reduce the vibration influence on the developer adjustment member 29.

[0068] In some embodiments, the first part 2911 can also be omitted, that is, the blade holder 291 no longer has the first part 2911. Correspondingly, the bending portion 2913 no longer exists. At this time, the structure of the developer adjustment member 29 can be simplified. The blade holder 291 as a whole no longer has an "L" shape but an "I" shape. The blade 292 is still fixed on the blade holder 291, and the blade holder 291 can still be fixed on the housing 2; further, to strengthen the strength of the blade holder 291, a reinforcing member continuously extending or intermittently arranged along the first direction can also be provided on the blade holder 291.

[0069] When the developing cartridge 1 is in operation, the developing member 31 needs to face the photosensitive member outside the developing cartridge so that the developer on the surface of the developing member 31 can reach the surface of the photosensitive member to achieve development. For this purpose, it is more beneficial to push the developing cartridge 1 towards the photosensitive member. As Figure 1C and Figure 2 shown, the developing cartridge 1 further includes at least one of a first forced-pushing portion 2b1 and a second forced-pushing portion 2b2 provided at the rear of the developing cartridge. The first forced-pushing portion 2b1 and the second forced-pushing portion 2b2 are used to receive the pushing force from outside the developing cartridge, and then force the developing member 31 and the photosensitive drum to remain in contact. Among them, the first forced-pushing portion 2b1 is located on the left side of the housing 2, and the second forced-pushing portion 2b2 is located on the right side of the housing 2. Specifically, the first forced-pushing portion 2b1 protrudes leftward from the left side of the housing 2, and the second forced-pushing portion 2b2 protrudes leftward from the right end cap 28. That is to say, along the first direction, both the first forced-pushing portion 2b1 and the second forced-pushing portion 2b2 protrude in the same direction. Therefore, both the first forced-pushing portion 2b1 and the second forced-pushing portion 2b2 can also protrude rightward. This structure is beneficial to the miniaturization of the developing cartridge 1.

[0070] In some embodiments, the developing cartridge 1 is further provided with a conductive bracket for supporting the conductive member 26. The conductive bracket is fixedly connected to the housing 2, and the second forced-pushing portion 2b2 can also be provided on the conductive bracket.

[0071] [Right end cap]

[0072] As Figure 1B shown, along the second direction, the right end cap 28 is located behind the conductive member 26. A part 282 of the right end cap 28 is formed as the second forced-pushing portion 2b2. A part of the acting component is exposed from the exposure port 281. When observed along the first direction, the right end cap 28 does not coincide with the powder filling port 2a3 provided at the detection end. When the developer in the developing cartridge is consumed, the user can directly replenish the developer into the developing cartridge without disassembling the right end cap 28. Along the third direction, the powder filling port 2a3 is located below the acting component 63. For the acting component set in a protruding shape, when the user replenishes the developer into the developing cartridge, not only will there be no interference with the acting component 63, but the acting component 63 and the powder filling port 2a3 can be observed by the user at the same time, and the probability of the acting component 63 being damaged is greatly reduced. Along the first direction, the powder filling port 2a3 is located between the second forced-pushing portion 2b2 / 282 and the conductive member 26.

[0073] [Paper guide plate]

[0074] When the developing cartridge 1 is in operation, along the third direction, the imaging medium (such as printing paper) will pass through the developing cartridge along the second direction from below the developing cartridge. To keep the movement path of the imaging medium stable, the developing cartridge 1 further includes a paper guide plate 2d provided below the housing 2. As Figure 1CAs shown, the guide paper plate 2d has a continuous surface that extends substantially along the first direction and the second direction. Preferably, the surface of the guide paper plate 2d is a smooth surface. More preferably, along the first direction, the surface of the guide paper plate 2d is a flat surface, and along the second direction, the surface of the guide paper plate 2d is a plurality of adjacent flat surfaces, and each two adjacent flat surfaces intersect at a line parallel to the first direction.

[0075] Continue as Figure 1C As shown, the developing cartridge 1 further includes a reinforcing rib 10f formed by extending downward from the housing 2. The guide paper plate 2d covers the reinforcing rib 10f, and the reinforcing rib 10f covered by the guide paper plate 2d is less likely to be broken.

[0076] The guide paper plate 2d and the housing 2 can be connected by means such as bonding, snap connection, or can be connected by welding.

[0077]

Driving Force Transmission Component

[0078] As Figure 2 shown, the driving force transmission component 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43, and a stirring member driving member 44. The developing member driving member 42 is coaxially arranged with the developing member 31 and is used to transmit the driving force from the driving force receiving member 41 to the developing member 31. The powder feeding member driving member 43 is coaxially arranged with the powder feeding member 32 and is used to transmit the driving force from the driving force receiving member 41 to the powder feeding member 32. The stirring member driving member 44 is coaxially arranged with the stirring member 33 and is used to transmit the driving force from the driving force receiving member 41 to the stirring member 33. When the stirring member driving member 44 is provided, the driving force transmission component 4 further includes an idler wheel 45 located between the driving force receiving member 41 and the detecting device 6. The driving force receiving member 41 transmits the driving force to the stirring member driving member 44 through the idler wheel 45, and then is transmitted to the detecting device 6 by the stirring member driving member 44. In some embodiments, the driving force transmitted to the detecting device 6 can also directly come from any one of the driving force receiving member 41, the developing member driving member 42, the powder feeding member driving member 43, and the idler wheel 45. It is feasible that the stirring member 33 can be arranged to rotate around an axis parallel to the first direction or can be arranged to reciprocate in a direction substantially parallel to the second direction. The driving force transmission method between the respective driving members can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving member is arranged as a gear.

[0079] The driving force receiving member 41 rotates around a second axis L2 parallel to the first direction. The detected member 9 is arranged as a rod that can rotate around a third axis L3 parallel to the first direction, and includes a rotating portion 93 and a first rod 91 and a second rod 92 connected to the rotating portion 93. Among them, the second rod 92 is used to interact with the detecting device 6, and the first rod 91 is used to be detected by the device.

[0080] In some embodiments, the powder feeding member driving member 43 is blocked by the left end cover 27 and not exposed. At this time, the powder feeding member driving member 43 is located between the housing 2 and the left end cover 27 and is protected.

[0081]

Detection Device

[0082] As Figure 2 shown, the detection device 6 includes a driving assembly 61 disposed at the driving end, an acting assembly 63 disposed at the detection end, and a transmission member 62 located between the driving assembly 61 and the acting assembly 63. After receiving the driving force, the driving assembly 61 drives the transmission member 62 to move in a direction not perpendicular to the first direction, thereby forcing the acting assembly 63 to interact with the detected member 9. Preferably, the moving direction of the transmission member 62 is parallel to the first direction. More preferably, the transmission member 62 reciprocates in a direction parallel to the first direction. In this way, the detection end of the developing cartridge does not need to be provided with components such as gears and ratchets for transmitting the driving force, or the number of components such as gears and ratchets for transmitting the driving force is reduced, and the structure of the detection end is simplified. When the developing cartridge is assembled, only the assembly of the driving end needs to be focused on.

[0083] [Driving Assembly]

[0084] The driving assembly 61 includes a driving member 612 and a counting member 613. The counting member 613 rotates around a fourth axis L4 parallel to the first direction, and at least a part of the counting member 613 is closer to the housing 2 than the driving member 612. The driving member 612 is used to engage with the stirring member driving member 44 and receive the driving force. Along the first direction, at least a part of the counting member 613 is closer to the housing 2 than the stirring member driving member 44. As Figure 4A and Figure 4B shown, along the first direction, at least the part of the counting member 613 for interacting with the transmission member 62 (such as the protrusion described below) is closer to the housing 2 / left surface 21 / right surface 22 than the driving member 612 and / or the stirring member driving member 44. Preferably, the whole counting member 613 is closer to the housing 2 / left surface 21 / right surface 22 than the driving member 612 and / or the stirring member driving member 44; further, along the first direction, at least a part of the counting member 613 is closer to the housing 2 / left surface 21 / right surface 22 than the idler gear 45 / driving force receiving member 41. In this way, the size of the developing cartridge 1 in the first direction can be reduced, which is beneficial to the miniaturization of the developing cartridge 1.

[0085] [Cut-off of the Driving Force of the Driving Assembly]

[0086] The counting member 613 and the driving member 612 may be integrally formed or separately formed. After the detection is completed, the separation mechanism provided in the developing cartridge 1 is used to make the counting member 613 stop moving and remain stationary. Specifically, in the case where the counting member 613 and the driving member 612 are integrally formed, after the detection is completed, the entire counting member 613 will no longer receive the driving force. For example, the entire counting member 613 can be forced to move in the first direction, or the entire counting member 613 can be translated, so that the counting member 613 is disengaged from the drive source (any one of the driving force receiving member 41, the developing member driving member 42, the powder feeding member driving member 43, the stirring member driving member 44, and the idler gear 45); in the case where the counting member 613 and the driving member 612 are separately formed, after the detection is completed, the counting member 613 and the driving member 612 can be disengaged, but the driving member 612 is not disengaged from the drive source, or the entire counting member 613 and the driving member 612 can be disengaged from the drive source; in some embodiments, regardless of whether the counting member 613 and the driving member 612 are integrally formed or not, the driving member 612 can also be set as a gear with a toothless part. During the detection process, the gear part of the driving member 612 faces the drive source and receives the driving force. When the detection is completed, the toothless part of the driving member 612 faces the drive source and does not receive the driving force. The toothless part is a kind of separation mechanism.

[0087] The counting member 613 includes a chassis 613a, a coupling part 613b, a driving force receiving part 613c, and a plurality of protrusions provided on the chassis 613a. The counting member 613 and the driving member 612 are coupled to each other through the coupling part 613b. The driving force of the driving member 612 is transmitted to the counting member 613 through the coupling between the driving force output part 6122 provided on the driving member 612 and the driving force receiving part 613c provided on the counting member 613.

[0088] When viewed along the rotation axis L4, the counting member 613 is circular, and its radius R can vary between 5.0 mm and 7.0 mm, preferably 5.5 mm to 6.5 mm. Especially in the structure where there are multiple gears provided at the driving end, if the diameter of the counting member 613 is too large, it is not conducive to the layout of other gears and will cause the failure of miniaturizing the developing cartridge 1; on the contrary, if the diameter of the counting member 613 is too small, the rotation speed of the counting member 613 will increase, which will further exacerbate the wear between the components of the driving force transmission assembly 4 and even cause the detection device 6 to fail in detection.

[0089] When both the driving force receiving member 41 and the driving member 612 are set as gears, the gear tooth ratio between the two ranges from 0.7 to 1.3, preferably 0.8 to 1.1. In the scheme where the transmission member 62 adopts translation, this tooth ratio is conducive to the miniaturization setting of the end of the powder cartridge and improves the transmission accuracy.

[0090] [Structure of the counting member]

[0091] like Figure 5 As shown, the multiple protrusions include a positioning protrusion 613d, a first toggle protrusion 613e and a second toggle protrusion 613f spaced apart along the circumferential direction of the chassis 613a, and a flat portion 613g is provided between two adjacent protrusions, wherein a first flat portion 613g1 is provided between the positioning protrusion 613d and the first toggle protrusion 613e, and a second flat portion 613g2 is provided between the first toggle protrusion 613e and the second toggle protrusion 613f, and the number of the toggle protrusions may be increased or decreased according to the detection requirements of the detection device.

[0092] [Structure and installation of transmission parts]

[0093] The transmission member 62 includes a forced pushing portion 621 (forced pushing member 620) located at the driving end, a transmission portion 623 located at the detection end, and a moving portion 622 located between the forced pushing portion 621 and the transmission portion 623. The forced pushing portion 621 is used to combine with the counting member 613 and receive the forced pushing force. Further, the transmission member 62 also includes a reset member 67. When the transmission member 62 is pushed to the right / detection end, the reset member 67 accumulates the reset force. When the transmission member 62 is no longer pushed, the reset force forces the transmission member 62 to move / reset to the left / driving end. In some embodiments, the reset member 67 may not be a separate component. At this time, the reset of the transmission member 62 drives the action component 63 through the reset of the detected member 9, and then the action component 63 forces the transmission member 62 to reset.

[0094] like Figure 3 As shown, along the third direction, the housing 2 includes an upper housing 2a located at the top and a lower housing 2b located at the bottom, the developer chamber 10 is located between the upper housing 2a and the lower housing 2b, and at least one of the developing member 31, the powder feeding member 32 and the stirring member 33 is rotatably arranged in the lower housing 2b, as shown in FIG. Figure 2 As shown, the guide groove 25 is arranged above the upper shell 2a, and the guide groove 25 is exposed upward, and the transmission member 62 is movably installed in the guide groove 25, so that the transmission member 62 will not interact with the developer during movement, and leakage of the developer is also avoided.

[0095] In some embodiments, the developing member 31 and the guiding groove 25 may also be both disposed on the upper housing 2a.

[0096] The developer box 1 further includes a cover 24 for preventing the transmission member 62 from falling off. The cover 24 covers the guide groove 25 from above. On the one hand, the transmission member 62 will not fall off from the guide groove 25, protecting the transmission member from external contact; on the other hand, the appearance of the developer box can be improved. The cover 24 can be combined with the housing 2 by means of snap connection, welding, bonding, magnetic attraction, etc.

[0097] As Figure 3A shown, the first forced push part 2b1 and the second forced push part 2b2 are arranged on the upper shell 2a. Along the first direction, the first forced push part 2b1 and the second forced push part 2b2 are arranged at intervals. Along the second direction, both the first forced push part 2b1 and the second forced push part 2b2 protrude downward from the rear of the upper shell 2a. This design can simplify the structure of the lower shell 2b with more components.

[0098] As Figure 3D shown, the first forced push part 2b1 can also be arranged on the left end cover 27, and the second forced push part 2b2 can also be arranged on the right end cover 28. This design is beneficial to simplifying the structure of the shell 2.

[0099] The driving force receiving member 41 includes at least one driving force receiving part 41a arranged at intervals along its rotation direction. The driving force receiving part 41a is used to be combined with the driving force output member in the imaging device to receive the driving force from the driving force output member. Continuing as Figure 3D shown, along the radial direction of the driving force receiving member 41, the driving force receiving part 41a is not blocked. During the process of the driving force receiving member 41 being combined with the driving force output member, the interference received by the driving force receiving member 41 can be reduced.

[0100] As Figure 3B shown, in some embodiments, the driving force receiving member 41 is further provided with an outer ring 41b. Along the radial direction of the driving force receiving member 41, the outer ring 41b is located radially outside the driving force receiving part 41a. At this time, the driving force receiving part 41a will be blocked.

[0101] When the upper shell 2a and the lower shell 2b are combined by welding, the welding surface 2g formed by welding the upper shell 2a and the lower shell 2b is located on at least one side wall of the lower shell 2b. When observed along the first direction, the welding surface 2g does not coincide with the driving force receiving member 41. Along the third direction, the welding surface 2g is located above the rotation axis L1 of the driving force receiving member 41.

[0102] As Figure 3B shown, in another shell 2, the upper shell 2a and the lower shell 2b can also be combined with each other in the second direction. The guiding groove 25 is arranged on the upper shell 2a. When observed along the first direction, the welding surface 2g also does not coincide with the driving force receiving member 41, or the welding surface 2g is located outside the projection range of the driving force receiving member 41. Along the third direction, a part of the welding surface 2g is located below the driving force receiving member 41 (as Figure 3C shown); in some embodiments, along the third direction, another part of the welding surface 2g is located above the rotation axis L1 of the driving force receiving member 41.

[0103] Specifically, along the second direction, the welding surface 2g is located behind the driving force receiving member 41. In this way, not only can the impact of the vibration generated when the driving force receiving member 41 rotates on the welding surface 2g be reduced, but also sufficient space can be ensured for the lower housing 2b. At the same time, the volume of the developer chamber 10 can be increased as much as possible.

[0104] As Figure 3C shown, the welding surface 2g can also be inclined relative to the second direction / the third direction. Figure 3C The welding surface 2g that is inclined from the front upper direction to the rear lower direction is shown by a dashed line in

[0105] During the operation / development of the developer cartridge 1, the developing member 31 needs to be in contact with the photosensitive drum 40 outside the developer cartridge. However, when the developer cartridge 1 is not operating / not developing, the developing member 31 and the photosensitive drum 40 should not continue to be in contact. For this reason, there has already been a solution of providing a biasing member in the imaging device and, at the same time, providing a force receiving member in the developer cartridge 1. When the developer cartridge 1 is not operating / not developing, the biasing member abuts against the force receiving member to apply and maintain a separating force to the force receiving member, thereby forcing the developing member 31 and the photosensitive drum 40 to separate from each other. When the developer cartridge 1 needs to operate / develop again, the biasing member no longer applies a separating force to the force receiving member, and the developing member 31 and the photosensitive drum 40 come into contact again.

[0106] Alternatively, when the developer cartridge 1 is not operating / not developing, after the biasing member abuts against the force receiving member to separate the developing member 31 and the photosensitive drum 40 from each other, the biasing member disengages from the force receiving member, and through a holding member provided in the developer cartridge, the developing member 31 and the photosensitive drum 40 are maintained in a separated state. When the developer cartridge 1 needs to operate / develop again, the biasing member applies a restoring force to the force receiving member, thereby forcing the developing member 31 and the photosensitive drum 40 to come into contact again.

[0107] Regardless of which of the above methods is used to achieve the contact and separation between the developing member 31 and the photosensitive drum 40, as long as at least a part of the developing member 31 does not contact the photosensitive drum 40 when the developer cartridge 1 is not operating / not developing. As Figure 3E shown, when the developer cartridge 1 is operating / developing, the developing member 31 is in contact with the photosensitive drum 40, and the rotation axis L1 of the developing member 31 is parallel to the rotation axis L4 of the photosensitive drum 40; when the developer cartridge 1 is not operating / not developing, the rotation axis L1 of the developing member 31 intersects with the rotation axis L4 of the photosensitive drum 40.

[0108] For example, a force receiving member is provided in the developing cartridge 1. Along the first direction, the force receiving member is located at the driving end or the detecting end. When the force receiving member receives a separating force, at the end where the force receiving member is provided, the developing member 31 and the photosensitive drum 40 are separated from each other. At the end where the force receiving member is not provided, the developing member 31 and the photosensitive drum 40 may still be in contact with each other or may be separated from each other, but the distance between the rotation axis L1 of the developing member 31 and the rotation axis L4 of the photosensitive drum 40 will change along the first direction. Figure 3F An example of providing a force receiving member at the driving end is shown. In this example, after the force receiving member receives the separating force, the developing member 31 rotates in the direction shown by r in the figure. At the driving end, the developing member 31 and the photosensitive drum 40 are separated from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along the first direction. Specifically, along the first direction, in the direction from the driving end to the detecting end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases; on the contrary, when the force receiving member is provided at the detecting end, after the force receiving member receives the separating force, at the detecting end, the developing member 31 and the photosensitive drum 40 are separated from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along the first direction. Specifically, along the first direction, in the direction from the detecting end to the driving end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases.

[0109] In some embodiments, the force receiving member is a protrusion provided on the left end cap 27.

[0110] In some embodiments, the force receiving member may also be at least a part of the outer ring 41b. Thus, the force applying member directly applies a separating force or a restoring force to the outer ring 41b, and then the outer ring 41b drives the housing 2 to move relative to the photosensitive drum 40 to realize the separation and contact between the developing member 31 and the photosensitive drum 40; in this deformation mode, preferably, along the first direction, the outer ring 41b passes through the left end cap 27, and along the radial direction of the driving force receiving member 41, the outer ring 41b is not blocked by the left end cap 27, so as to facilitate the force applying member to apply a separating force or a restoring force to the outer ring 41b.

[0111] [Structure of the acting component]

[0112] As Figure 8A - Figure 8F shown, the acting component 63 is arranged to be rotatable about the axis L5. During the rotation process, the acting component 63 interacts with the detected component 9. The axis about which the acting component 63 rotates can be parallel to any one of the first direction, the second direction, and the third direction. Hereinafter, an example in which the axis L5 is perpendicular to the first direction is taken.

[0113] The actuating component 63 includes a rotating part 631, an actuating protrusion 632 and a passive part 633 extending from the rotating part 631. Along a direction perpendicular to the rotation axis L5, the actuating protrusion 632 is arranged in a non-linear extension manner, and can either directly extend from the rotating part 631 or extend from a connecting part 636 connected to the rotating part 631, as Figure 6A shown. The actuating protrusion 632 is claw-shaped as a whole, and a groove / avoidance part 6323 is arranged in the actuating protrusion 632 and recesses in a direction opposite to the rotation direction r3 of the actuating component 63. As Figure 6B and Figure 6C shown, when the actuating protrusion 632 rotates with the rotating part 631, the actuating part 6324 of the actuating protrusion 632 will directly contact the surface 921 of the second rod 92 facing the actuating protrusion 632 (as Figure 8B shown), instead of the actuating protrusion 62 first contacting the edge 922 and then contacting the surface 921. The edge 922 is the boundary line of the surface 921 close to the housing 2 / the transmission part 62 / the actuating component 63 side.

[0114] Continuing as Figure 6A and Figure 6B shown, two surfaces 6321 / 6322 with different heights are formed above the actuating protrusion 632, and there is a height difference between them. In this way, the position where the actuating part 6324 of the actuating protrusion 632 for abutting against the second rod 92 contacts the second rod 92 can be moved downward; accordingly, when the actuating protrusion 632 is arranged to be able to contact different positions of the detected part 9, the rotation speed of the detected part 9 can be made different, and the detection function can also be realized.

[0115] Figure 7A and Figure 7B show the structure of another actuating protrusion 632. Different from the above embodiment, in this embodiment, an inclined surface 6325 and a flat surface 6326 are arranged on the side of the actuating protrusion 632 facing the second rod 92, and the groove / avoidance part 6323 extends in the third direction in the flat surface 6326 and the inclined surface 6325. When the actuating protrusion 632 contacts the second rod 92, similarly, the edge 922 will not contact the actuating protrusion 632, and the actuating part 6324 directly contacts the surface 921.

[0116] Next, in combination with Figure 9 , Figure 10A and Figure 10B describe the deformation embodiments of the actuating component 63.

[0117] Deformation 1

[0118] As Figure 9As shown, the acting component 63 includes a toggling member 634 rotatable about a rotation axis L5 and an active member 64 for driving the toggling member 634. The active member 64 includes a base 641 and an active portion 642 movable relative to the base 641. Among them, the active member 642 is arranged to be rotatable only in one direction. The toggling member 634 includes a central shaft 6340, a first toggle rod 6341, a second toggle rod 6342 and a ratchet wheel 6343 combined with the central shaft. The ratchet wheel 6343 is used to be pushed by the active portion 642. Preferably, the ratchet wheel 6343 is arranged at one end of the central shaft 6340. The first toggle rod 6341 and the second toggle rod 6342 respectively extend radially outward from the surface of the central shaft 6340. Along the rotation axis L5, the first toggle rod 6341 and the second toggle rod 6342 are distributed at different axial positions, that is, the distances between the first toggle rod 6341 and the second toggle rod 6342 and any one end of the central shaft 6340 are different. Or rather, the first toggle rod 6341 and the second toggle rod 6342 have a height difference. In this way, the positions where the first toggle rod 6341 and the second toggle rod 6342 toggle the detected member 9 are different.

[0119] During the detection process, the transmission portion 623 moves towards the right side / detection end and pushes the active member 64. Furthermore, the active portion 642 pushes the ratchet wheel 6343 to rotate. The first toggle rod 6341 or the second toggle rod 6342 abuts against the second rod 92. When the transmission portion 623 no longer pushes the active member 64, the active member 64 is pushed by a component such as an elastic member to reset. As Figure 10A shown, the first toggle rod 6341 contacts the surface 921 of the second rod at point Q1. As the ratchet wheel 6343 is toggled, the detected member 9 is pushed to rotate in the direction shown by r around the rotating portion 93 until the first toggle rod 6341 disengages from the second rod 92. As the ratchet wheel 6343 continues to rotate, the second toggle rod 6342 begins to contact the second rod 92 at point Q2. Compared with point Q1, point Q2 is farther from the free end 923 of the second rod 92. That is to say, point Q2 is closer to the rotating portion 93 than point Q1. When the rotation speed of the ratchet wheel 6343 remains unchanged, the detected member 9 will rotate faster under the push of the second toggle rod 9342, thus forming a phenomenon that the detected member 9 is accelerated.

[0120] For the active member 64, after the active portion 642 pushes the ratchet wheel 6343, during the process of the elastic member forcing the active member 64 to reset, the active portion 642 is supported by the ratchet wheel 6343 and rotates. In this way, the active portion 643 can enter the position for the next push of the ratchet wheel 6343. In some embodiments, the active member 64 is connected to the transmission portion 623 and can move along with the movement of the transmission portion 623.

[0121] Variant Two

[0122] In this variant embodiment, the acting component 63 and the transmission member 62 are combined in the form of a gear and a rack. AsFigure 11A , Figure 11B , Figure 12A and Figure 12B As shown, the transmission part 623 is configured as a rack, and the action component 63 includes a rotating part 631, an action protrusion 632 connected to the rotating part 631, and a passive part 633, wherein the passive part 633 is configured as a gear, and preferably, the rotating part 631 and the gear 633 are coaxially arranged. When the transmission member 62 is pushed to the right / detection end, the rack drives the gear to rotate, thereby causing the rotating part 631 to drive the action protrusion 632 to swing, and during the swinging process of the action protrusion 632, the second rod 92 is toggled.

[0123] [Delayed movement of the counting element]

[0124] In some embodiments, the detected member 9 is configured to be moved only after the driving force receiving member 41 has been driven for a period of time. At this time, the rotational movement of the counting member 613 needs to be delayed, that is, the driving force received by the driving force receiving member 41 is not immediately transmitted to the counting member 613.

[0125] It is achievable that, along the rotation direction of the counting member 613, a predetermined distance is provided between the driving force output portion 6122 of the driving member 612 and the driving force receiving portion 613c provided on the counting member 613. In this way, when the driving member 612 starts to rotate, the driving force will not be immediately transmitted to the counting member 613, and the counting member 613 remains stationary. When the driving force output portion 6122 contacts the driving force receiving portion 613c, the counting member 613 starts to rotate, and the delay requirement of the counting member 613 is realized.

[0126] like Figure 13 As shown, the driving member 612 is driven by the stirring member gear 44, and the counting member 613 and the driving member 612 are integrally formed as an example for description. The stirring member gear 44 is configured as a double gear. Along the first direction, the stirring member gear 44 includes a first gear 441 located on the left and a second gear 442 located on the right, wherein the first gear 441 is a full-tooth gear for receiving the driving force of the driving force receiving member 41, and the second gear 442 is also a full-tooth gear for being opposite to the driving member 612 and transmitting the driving force to the driving member 612.

[0127] The driving member 612 is a toothless gear, that is, on the same circumferential surface of the driving member 612, a part of the circumferential surface of the driving member 612 is provided with teeth to form a toothed portion 612a, and the other part is without teeth to form a toothless portion 612b; along the first direction, an intermediate portion 443 is formed between the first gear 441 and the second gear 442, and the shifting portion 4411 is provided in the intermediate portion 443, and a shifted portion 612c is provided on the driving member 612 corresponding to the shifting portion 4411. When the developing box is assembled, along the first direction, the shifting portion 4411 and the shifted portion 612c are both located between the first gear 441 and the second gear 442, the shifted portion 612c is located on the rotation path of the shifting portion 4411, and the toothless portion 612b is opposite to the second gear 442. That is to say, even if the agitator gear 44 starts to rotate around the rotation axis L7 along the rotation direction r2, the driving member 612 will not be driven.

[0128] As the stirring member gear 44 continues to rotate, the toggle portion 4411 begins to toggle the toggle portion 612c. At this time, the driving member 612 begins to rotate. When the toggle portion 4411 is disengaged from the toggle portion 612c, the toothed portion 612a begins to mesh with the second gear 442. In this way, the driving member 612 / counting member 613 is driven by the stirring member gear 44, and then the detected member 9 begins to be detected. The delay time of the driving member 612 / counting member 613 is the time required for the toggle portion 4411 to start to contact the toggle portion 612c as the stirring member gear 44 starts to rotate. It is understandable that the designer can also adjust the position of the toggle portion 4411 according to the delay requirement of the device for the detected member 9, so that the moment when the toggle portion 4411 starts to contact the toggle portion 612c changes.

[0129] Preferably, the toggle portion 4411 is formed integrally with one of the teeth of the first gear 441 , so that the strength of the toggle portion 4411 can be enhanced. Along the first direction, the toggle portion 4411 is arranged closer to the second gear 442 than the teeth of the first gear 441 .

[0130] [Acceleration of the test piece]

[0131] As described above, in some embodiments, when the detection period of the detection device 6 is about to end (the end of the detection period), the detected member 9 needs to be accelerated, otherwise, the developing box will not be recognized by the device. To achieve the acceleration of the detected member 9, it can be achieved by accelerating the counting member 613, accelerating the transmission member 62, and moving the second rod 92 to different positions. Other implementation methods are described below.

[0132] Method 1

[0133] Combine the following Figure 14 , Figure 15A and Figure 15BDescribe another way to accelerate the counting part 613 - Method 1.

[0134] In this embodiment, still taking the counting part 613 and the driving part 612 being integrally formed as an example, the separating mechanism includes an elastic pushing part 611. The driving part 612 is set as a gear with missing teeth. Further, the driving part 612 also includes an arc surface 6124 coaxially arranged with the gear with missing teeth and a straight surface 6125 arranged adjacent to the arc surface. The elastic pushing part 611 is set as a torsion spring. One end of the torsion spring abuts against the driving part 612, and the other end abuts against a component outside the driving part 612.

[0135] As Figure 15A shown, before the detection device 6 reaches the end of the detection section, the torsion spring 611 abuts against the arc surface 6124 and does not hinder the rotation of the driving part 612. When the detection device 6 reaches the end of the detection section, the torsion spring 611 disengages from the arc surface 6124 and begins to abut against the straight surface 6125. During the process of the torsion spring 611 changing the contact surface, the torsion spring 611 releases the torsion force, thereby forcing the driving part 612 to rotate at an accelerated speed. Further, an opening 6123 is also provided on the driving part 612 to facilitate the user to reset the torsion spring 611 from the outside.

[0136] Method 2

[0137] The acceleration of the driving part 612 can also be achieved by setting the second gear 442 of the stirring part gear 44 as a gear with missing teeth. The diameter of the second gear 442 is smaller than that of the first gear 441. At the same time, the driving part 612 is also set as a double - linked gear. Along the first direction, the driving part 612 has a main gear meshing with the first gear 441 and a sub - gear opposite to the second gear 442. During the detection process, the first gear 441 drives the main gear to rotate. When reaching the end of the detection section of the detection device 6, the first gear 441 disengages from the driving gear, and the second gear 442 begins to mesh with the sub - gear. Since the diameter of the second gear 442 is smaller than that of the first gear 441, when the second gear 442 drives the sub - gear, the driving part 612 will be accelerated.

[0138] Example 2

[0139] In this embodiment, the same components as those in the above - mentioned embodiment are numbered the same.

[0140] As Figure 16A and Figure 16BAs shown, the transmission member 62 includes a pushed member 620 at the driving end, a transmission portion 623 at the detection end, and a moving portion 622 between the pushed member 620 and the transmission portion 623. Different from the above embodiments, in this embodiment, the pushed member 620, the moving portion 622, and the transmission portion 623 are formed separately from each other in pairs. Further, the pushed member 620 is arranged to be rotatable about the rotation axis L9, and the transmission portion 623 is arranged to be rotatable about the rotation axis L10. Preferably, the rotation axis L9 and the rotation axis L10 are not perpendicular to the third direction respectively. More preferably, the rotation axis L9 of the pushed member 620 and the rotation axis L10 of the transmission portion 623 are parallel to the third direction respectively.

[0141] The pushed member 620 is used to cooperate with the counting member 613. Specifically, the pushed portion 621 is arranged to radially protrude from the pushed member 620 to cooperate with the counting member 613 and receive the pushing force; the acting protrusion 632 is integrally or separately formed with the transmission portion 623. When the transmission portion 623 rotates about the rotation axis L10, the acting protrusion 632 moves along with the transmission portion 623, such as rotating or translating, to interact with the second rod 92; one end of the reset member 64 abuts against the pushed member 620, and the other end abuts against the housing 2. The reset member 64 can be a compression spring or a tension spring.

[0142] Further, the pushed member 620 is provided with a first engaging portion 620a, the transmission portion 623 is provided with a second engaging portion 623a, one end of the moving portion 622 is provided with a first engaged portion 622a rotatably engaged with the first engaging portion 620a, and the other end is provided with a second engaged portion 622b rotatably engaged with the second engaging portion 623a. Preferably, the combination between the first engaging portion 620a and the first engaged portion 622a is an axial hole fit. Similarly, the combination between the second engaging portion 623a and the second engaged portion 622b is also an axial hole fit.

[0143] The pushed portion 621 receives the pushing force, causing the pushed member 620 to rotate along the rotation direction r6, thereby driving the moving portion 622 to move in the first direction towards the detection end (the other end 52 in the first direction), and driving the transmission portion 623 to rotate along the rotation direction r7, and further causing the acting protrusion 632 to toggle the second rod 92. At this time, the reset member 64 is compressed or stretched to accumulate the reset force. When the pushed portion 621 no longer receives the pushing force, the reset force of the reset member 64 causes the pushed member 620 to rotate in the direction opposite to the rotation direction r7, thereby driving the moving portion 622 to move in the first direction away from the detection end (one end 51 in the first direction), and driving the transmission portion 623 to rotate in the direction opposite to the rotation direction r7, and further causing the acting protrusion 632 to no longer toggle the second rod 92.

[0144] Further, the driving member 612 and the counting member 613 can be formed separately or integrally. In this embodiment, a cam can be used to replace the counting member 613, and only one driving member 612 is provided.

[0145] Further, a crank - connecting rod structure is formed between the forced - pushing member 620 and the moving part 622, and between the moving part 622 and the transmission part 623 in this embodiment.

[0146] Example 3

[0147] On the basis of Embodiment Nine, this embodiment will deform some structures of the transmission member 62. The same components in this embodiment and the above - mentioned embodiments have the same numbers.

[0148] As Figure 17 shown, the transmission member 62 includes a forced - pushing member 620 and a moving part 622 formed separately. Different from that, in this embodiment, the moving part 622 and the transmission part 623 in Embodiment Two are set as one body. Further, the forced - pushing member 620 is set to be rotatable about the rotation axis L9. Preferably, the rotation axis L9 is not perpendicular to the third direction. More preferably, the rotation axis L9 is parallel to the third direction. The moving part 622 is set to be movable along the first direction, for example, translation. The acting protrusion 632 is arranged on the side of the moving part 622 close to the detection end. The acting protrusion 632 can be an additionally arranged component or the end of the moving part 622 close to the detection end to interact with the second rod 92.

[0149] Further, the moving part 622 is set to move along a guiding groove (not shown) provided in the housing 2 to prevent the moving part 622 from generating too large an offset in the second direction and being unable to move along the correct direction, resulting in the acting protrusion 632 being unable to interact with the second rod 92 or the acting protrusion 632 touching the second rod 92 at the wrong moment.

[0150] Further, the forced - pushing member 620 and the moving part 622 can be combined by means of shaft - hole fit. For example, the forced - pushing member 620 is provided with a first combining part 620a, and the moving part 622 is provided with a first combined part 622a combined with the first combining part 620a, and the first combining part 620a and the first combined part 622a are rotatably combined.

[0151] Further, a crank - connecting rod structure is formed between the forced - pushing member 620 and the moving part 622 in this embodiment.

[0152] Example 4

[0153] The same components in this embodiment and the above - mentioned embodiments have the same numbers.

[0154] AsFigure 18A and Figure 18B As shown in Figure 18B , the transmission member 62 includes a pushed member 620 at the driving end, a transmission portion 623 at the detection end, and a motion portion 622 between the pushed member 620 and the transmission portion 623. The pushed member 620 is arranged to be rotatable about the rotation axis L9, and the transmission portion 623 is arranged to be rotatable about the rotation axis L10. Preferably, the rotation axis L9 and the rotation axis L10 are not perpendicular to the third direction respectively. More preferably, the rotation axis L9 of the pushed member 620 and the rotation axis L10 of the transmission portion 623 are parallel to the third direction respectively.

[0155] The difference between this embodiment and the above embodiment is that in this embodiment, the pushed member 620, the motion portion 622, and the transmission portion 623 are configured as a gear-rack structure. Further, the counting member (transition member) 613 is arranged as a gear (a kind of rotating body) that can rotate about the rotation axis L8. The structure of the counting member 613 is simplified. At the same time, the pushed member 620 is also arranged as a gear structure and is combined with the counting member 613. One end of the motion portion 622 is provided with a first engaged portion 622a, and the other end is provided with a second engaged portion 622b. The first engaged portion 622a and the second engaged portion 622b are provided with teeth. Specifically, the first engaged portion 622a is used to engage with the pushed member 620, and the second engaged portion 622b is used to engage with the transmission portion 623. In this embodiment, the acting protrusions 632 can be set to one or more according to the detection needs. Specifically, there are three acting protrusions 632, including a first acting protrusion 632a, a second acting protrusion 632b, and a third acting protrusion 632c. Further, the acting protrusions 632 are integrally or separately formed with the transmission portion 623. Optionally, in this embodiment, the first engaged portion 622a of the motion portion 622 can also be directly meshed with the counting member 613. In this way, the structure of the transmission member 62 can be simplified.

[0156] Further, a guide rod 25a is also arranged in the guide groove 25 provided in the housing 2, thereby forming a groove 252 for guiding the movement of the motion portion 622.

[0157] During detection, the driving member 612 drives the counting member 613 to rotate in the direction shown by r5, and drives the pushed member 620 to rotate in the direction shown by r6, thereby driving the motion portion 622 to move along the groove 252 towards the other end 52 in the first direction, and further driving the transmission portion 623 to rotate in the direction shown by r7, so that the three acting protrusions 632 sequentially touch the second rod 92.

[0158] Example 5

[0159] According to the inventive concept of the present utility model, the technical solutions involved in the above embodiments can also be applied to this embodiment. Therefore, the same components in this embodiment as those in the above embodiments are numbered the same.

[0160] As Figure 19A and Figure 19B shown, different from Embodiment Four, in this embodiment, the moving part 622 is set as a plurality of meshing gears, and the number of gears included in the moving part 622 is set between 8 and 13. In some embodiments, the moving part 622 includes nine meshing gears, among which the gear meshing with the counting part 613 can also be regarded as the forced pushing part 620.

[0161] The forced pushing part 620 is set to be rotatable around the rotation axis L9, and the transmission part 623 is set to be rotatable around the rotation axis L10. In one embodiment, the rotation axis L9 and the rotation axis L10 are not perpendicular to the third direction respectively. In one embodiment, the rotation axis L9 of the forced pushing part 620 and the rotation axis L10 of the transmission part 623 are parallel to the third direction respectively.

[0162] In some embodiments, the diameter of the counting part 613 is smaller than the diameter of the gear 620 meshing with it to achieve smooth transmission of the driving force.

[0163] As mentioned above, in some embodiments, the rotation axis of the driving part 612 intersects with the rotation axis of the counting part 613. The driving part 612 includes a driving force input part 6128 and a driving force output part 6122 arranged coaxially (as Figure 19B shown). The driving force input part 6128 is used to receive the driving force of the driving force receiving part 41, and it can be set as a full-tooth gear or a cylinder with a rough surface, etc. The driving force output part 6122 is used to transmit the driving force to the counting part 613, and it can be set as a bevel gear.

[0164] In some embodiments, the counting part 613 is set as a double gear, including a first-stage gear for engaging with the driving part 612 and a second-stage gear for engaging with the moving part 622. Among them, when the driving force output part 6122 in the driving part 612 is set as a bevel gear, the first-stage gear of the counting part 613 is preferably set as a bevel gear meshing with the bevel gear 6122.

[0165] In some embodiments, the driving part 612, the counting part 613 and the moving part 622 are all arranged on the upper housing 2a. In this way, the lower housing 2b can have more space to arrange other components such as the driving force transmission assembly 4, the chip assembly 11, etc.

[0166] In some embodiments, the driving member 612, the counting member 613, the moving part 622, the driving force transmission assembly 4, the chip assembly 11, the developing member 31, and the powder feeding member 32 are all disposed on the upper housing 2a.

[0167] In some embodiments, the moving part 622 can also be arranged to include twelve meshing gears.

[0168] At least a part of the plurality of gears is disposed in the guiding groove 25 to prevent the gears from falling off. When the covering member 24 covers the guiding groove 25, the risk of the gears falling off can be further reduced.

[0169] The plurality of gears are rotatably mounted by mounting posts 253 (as shown in Figure 3C and Figure 19A shown) disposed on the guiding groove 25 or the covering member 24. Each gear in the transmission part 622 corresponds to a mounting post 253 to ensure that the gears can be stably mounted and the driving force can be stably transmitted.

[0170] Preferably, along the second direction, the plurality of gears (moving part 622) are located behind the developer adjusting member 29 / driving force receiving member 41. Specifically, the driving force receiving member 41 is located between the developer adjusting member 29 and the plurality of gears (moving part 622), and the moving part 622 is located between the developer adjusting member 29 and the chip 7. On the one hand, the influence on the developer adjusting member 29 during the transmission of the plurality of gears can be reduced, and on the other hand, the influence of the vibration generated when the driving force receiving member 41 rotates on the plurality of gears can be reduced.

[0171] In some embodiments, as shown in Figure 19A shown, the plurality of gears are arranged in a straight line. For example, when viewed along the third direction, the connecting line of the rotation centers of the plurality of gears is a straight line. Preferably, the connecting line of the rotation centers of the plurality of gears is parallel to the first direction. Further, when viewed along the first direction, at least a part of the plurality of gears overlaps with the bevel gear 6122 to make full use of the space of the developing cartridge.

[0172] During detection, the driving member 612 drives the counting member 613 to rotate in the direction shown by r5 (as shown in Figure 18B shown). The driving force is transmitted to the transmission part 623 through gear transmission, so that the three acting protrusions 632 sequentially touch the second rod 92. In the above embodiments, the direction of the rotation axis L9 of the forced pushing member 620 and / or the direction of the rotation axis L10 of the transmission part 623 can also be adjusted according to design requirements.

[0173] The action protrusion 632 is formed integrally or separately with the transmission part 623. When the transmission part 623 rotates around the rotation axis L10, the action protrusion 632 moves with the transmission part 623, such as rotating or translating, to interact with the second rod 92; one end of the reset member 64 abuts against the forced push member 620, and the other end abuts against the shell 2. The reset member 64 can be a compression spring or a tension spring.

[0174] As described above, the rotation axis L7 of the action protrusion 632 can be parallel to any one of the first direction, the second direction and the third direction. In a preferred embodiment, the rotation axis L7 is arranged to intersect with the first direction. More preferably, the rotation axis L7 is perpendicular to the first direction. Specifically, in a plane including the first direction and the second direction, the projection of the rotation axis L7 is a straight line rather than a point. Preferably, the straight line formed by the projection of the rotation axis L7 in the plane intersects with the first direction. More preferably, the straight line formed by the projection of the rotation axis L7 in the plane is perpendicular to the first direction.

[0175] In some embodiments, the detection device 6 is not in contact with the second rod 92 through the action protrusion 632, but a shift block is additionally provided. The shift block can be driven by the action protrusion 632 to rotate around a rotation axis that is not parallel to the first direction, thereby shifting the second rod 92. Therefore, the shift block can be regarded as a part of the action component 63. The rotation axis of the shift block can be, for example, parallel to the second direction, or parallel to the third direction, or inclined relative to any one of the first direction, the second direction and the third direction; in this deformation mode, the action protrusion 632 can also be set to move along a straight line, and during the movement of the action protrusion 632, the shift block is driven by the action protrusion 632.

[0176] In some embodiments, the covering member 242 for covering the guide groove 25 is also provided with a reset hole for allowing the counting member 613 to be reset. When observed along the third direction, a portion of the counting member 613 is exposed through the reset hole, through which the user can use fingers or special tools to reset the counting member 613; in addition, the reset hole is configured to be exposed upward, which is also convenient for the user to perform the reset operation.

[0177] In some embodiments, the covering member 24 is further provided with an abutting protrusion for abutting against at least one of the driving member 612, the counting member 613, the moving part 622, the transmission part 623, and the acting component 63. Specifically, at least one of the above-mentioned driving member 612, counting member 613, moving part 622, transmission part 623, and acting component 63 is provided with an abutted part. Through the abutment of the abutting protrusion and the abutted part, the following beneficial effects can be achieved: Firstly, the abutting protrusion can limit the reverse rotation of the abutted part. Secondly, when the detection is completed, the abutting protrusion can also limit the continuous rotation of the abutted part. Thirdly, the abutting protrusion can also position the abutted part. When the abutted part is toggled past the abutting protrusion, the abutted part can be reset.

[0178] In some embodiments, the abutted part is provided on any one of the moving parts 622, and the abutting protrusion can be provided at a corresponding position on the covering member 242 according to the overall design requirements of the developing cartridge 100. Preferably, the abutted part is provided on the gear among the plurality of gears that meshes with the transmission part 623.

[0179] In some embodiments, the acting component 63 has a surface for toggling the second rod 92, and when observed in the first direction, the surface is within the projection range of the counting member 613, which is beneficial to reducing the size of the developing cartridge in the second direction.

[0180] In some embodiments, the moving part 622 is provided as a flexible member such as a flexible belt or a flexible rope. The flexible member 622 can move back and forth in the first direction, which can solve the technical problem of excessive load on the stirring rod in the background art, and can also make the positions of the transmission part 623 and the acting protrusion 632 more flexible, which is beneficial to improving the design freedom of the developing cartridge 1. In addition, the flexible member is not easily broken and has better stability.

[0181] In some embodiments, the moving part / flexible member 622 can be directly connected to the counting member 613, which can simplify the structure of the transmission member 62.

[0182] In some embodiments, one end of the flexible member 622 is directly connected to the counting member 613, and the other end is connected to the transmission part 623. Moreover, during detection, the flexible member 622 will wind around the counting member 613 and be released by the transmission part 623 at the same time. It can be achieved that the counting member 613 in this embodiment is also provided as a rotating body with partial tooth gaps in its circumferential direction to cut off the transmission of the driving force.

[0183] Example 6

[0184] As Figure 20As shown, a moving part (gear) 622 for engaging with a transmission part 623 is provided with a toothless part 612b. After the detection is completed, the transmission of the driving force inside the moving part 622 is cut off through the toothless part 612b.

[0185] It is achievable that the toothless part 612b can be provided on at least one of the multiple gears in the moving part 622, and can also be provided on at least one of the driving part 612, the counting part (transition part) 613, the forced pushing part 620, and the transmission part 623.

[0186] In some embodiments, it is also possible to cut off the transmission of the driving force by setting at least one of the multiple gears to be movable along its rotation axis or in a direction intersecting with its rotation axis. Accordingly, the above-mentioned toothless part and the acting mechanism for forcing at least one of the multiple gears to move along its rotation axis or in a direction intersecting with its rotation axis can be collectively referred to as a cutting device. Through this cutting device, the driving force transmitted to the acting component 63 will be cut off; according to the above description, the cutting device can be provided on at least one of the driving component 61 and the transmission part 62.

[0187] In this embodiment, at least one of the driving part 612 and the transition part 613 is provided with a bevel gear. In this way, the rotation axes of the driving part 612 and the transition part 613 do not have to be parallel or coincident with each other, but can be set to intersect. Thus, the design freedom of the detection device 6 and the developing cartridge 1 can be improved; preferably, the rotation axes of the driving part 612 and the transition part 613 are perpendicular to each other.

[0188] Continue as Figure 20 As shown, in some embodiments, the positions of the three acting protrusions 632 are different. Specifically, along a third direction intersecting with the first direction, the first acting protrusion 632a, the second acting protrusion 632b, and the third acting protrusion 632c are arranged in a staggered manner. Therefore, the positions where each acting protrusion touches the second rod 92 are different. The acting protrusion (such as Figure 20 the third acting protrusion 632c in Figure 20 ) that touches the second rod 92 closest to the rotating part 93 will be able to make the detected part 9 swing at the largest angle, and at the same time, the swinging speed of the detecting part 9 / second rod 92 is also the largest. The acting protrusion (such as Example 7

[0189] the first acting protrusion 632a in Figure 20 ) that touches the second rod 92 farthest from the rotating part 93 will be able to make the detected part 9 swing at the smallest angle, and at the same time, the swinging speed of the detecting part 9 / second rod 92 is also the smallest.In the above embodiments, it is described that the second forced pushing part 2b2 is provided on the housing 2 or the right end cover 28. In some embodiments, the second forced pushing part 2b2 can also be provided at other positions. For example, the second forced pushing part 2b2 is provided on the sealing cover 2a4. This design is beneficial to simplifying the structure of the housing 2, and the second forced pushing part 2b2 can also serve as an operating part for the user to operate the sealing cover 2a4.

[0190] In some embodiments, the second forced pushing part 2b2 can also be provided on an independent component 2i (as Figure 21 shown). The function of the independent component 2i can be designed according to the design requirements of the developing cartridge 1. For example, a part of the detecting device 6 is supported by the independent component 2i. In this embodiment, the right end cover 28 can be regarded as the independent component 2i.

[0191] As Figure 21 shown, along the first direction, the powder filling port 2a3 is arranged on the same side as the acting component 63. Along the third direction, the powder filling port 2a3 does not overlap with the acting component 63. Along the second direction, the powder filling port 2a3 is located in front of the independent component 2i. This design can not only ensure that the powder filling port 2a3 is directly exposed, so that the user does not need to disassemble the components of the developing cartridge to supplement the developer into the developer chamber 10, but also can reduce the size of the independent component 2i in the front-back direction, thereby reducing the cost of the independent component 2i and enhancing the strength of the independent component 2i. Preferably, along the third direction, a part of the independent component 2i overlaps with the acting component 63. Continuing as Figure 21 shown, when observing along the first direction, the rotation axis L2 of the driving force receiving member 41 / the intermediate gear 46 does not pass through the conductive member 26. In this way, the electrical contact between the conductive member 26 and the power output member in the imaging device can be less affected by the vibration generated when the driving force receiving member 41 rotates, and the stability of the electrical contact can be improved.

[0192] Furthermore, when observing along the first direction, the power input portion 26b of the conductive member 26 is located outside the projection range of the driving force receiving member 41. This design can improve the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device; furthermore, the power input portion 26b is also located outside the projection range of the intermediate gear 46, thereby further improving the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device.

[0193] In the above-described Second Embodiment to Sixth Embodiment, the driving force is no longer transmitted through the stirring member 33, which can reduce the load on the stirring member 33, thereby avoiding breakage of the stirring member 33. Moreover, the forced pusher and the moving part are formed integrally. In this way, the strength of each component can also be increased, thereby avoiding deformation or transmission lag caused by excessive length of a certain component in the first direction resulting in insufficient strength. Additionally, a flexible member with better stability is used as the moving part, thereby improving the durability and detection accuracy of the detection device.

[0194] Eighth Embodiment

[0195] Based on the above-described embodiments, the present invention further provides a developing cartridge without a stirring frame 33 to simplify the structure of the developing cartridge and save costs. As Figure 22 shown, the stirring frame 23 is no longer provided in the developer chamber 10. To ensure that the developer smoothly reaches the developing member 31 and the powder feeding member 32, the lower side plate 2b3 of the lower housing 2b is provided to be inclined relative to the second direction. Specifically, the inner surface 2b4 of the lower side plate 2b3 facing the developer chamber 10 is inclined relative to the second direction. Thus, the structure of the developing cartridge 1 can be simplified. When the user installs and disassembles the developing cartridge 1, the user can directly contact the lower side plate 2b3 with the hand. Compared with the handle 23, the lower side plate 2b3 has a larger area for the user to grip.

[0196] In Figure 22 the shown angle, the first straight line P1 passes through the rotation axis L1 of the developing member 31 and the rotation axis L2 of the driving force receiving member 41 at the same time. The second straight line P2 is parallel to the inner surface 2b3. The first straight line P1 and the second straight line P2 intersect at point P0, and the included angle γ formed between the two satisfies: 0° < γ ≤ 45°, preferably, 5° < γ ≤ 20°.
