[0063] It should be understood that the following embodiments are not isolated from each other, and those skilled in the art can combine the structures of the following embodiments according to design requirements.

[0064] Example 1

[0065]

Overall structure of the developing cartridge

[0066] The developing cartridge 1 includes a housing 2 forming a developer chamber 10 and a rotating member 3 rotatably mounted in the housing 2. The rotating member 3 can be, for example, a developing member 31 for delivering the developer outwards, 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, on the one hand, preventing the developer from caking, and on the other hand, delivering the developer towards the powder feeding member 32; the developing cartridge further includes a handle 23 connected to the housing 2, and the developing member 31 and the handle 23 are respectively located at both ends of the housing 2 along the installation direction.

[0067] 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 (the installation and removal direction of the developing cartridge 1) perpendicular to the first direction and a third direction perpendicular to both the first direction and the second direction. 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 top of the developing cartridge, and the other end 56 of the third direction points to the bottom of the developing cartridge.

[0068] 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 assembly 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.

[0069] The housing 2 has a left surface 21 facing left, a right surface 22 facing right, 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 1B shown, the right end cover 28 has an exposure port 281, and the size of the exposure port 281 is larger than the size of the component (the following acting component 63) of the detection device 6 located at the detection end; further, the developing cartridge 1 further includes a developer adjusting 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 cover 27, and the right end cover 28. The chip assembly 11 can be a chip simultaneously provided with a substrate, electrical contacts, and a storage part, or can be a component having a substrate, electrical contacts, a storage part, and a movable part that can be movably connected to the electrical contacts. The conductive member 26 is located at the detection end and is used to receive power from the device to supply power to the developing member 31.

[0070] When the developing cartridge 1 works, 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 reason, it is more advantageous to push the developing cartridge 1 towards the photosensitive member, as Figure 1C and Figure 2As shown, the developing cartridge 1 further includes a first forced pushing portion 2b1 and a second forced pushing portion 2b2 disposed behind the developing cartridge. 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, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 can also both protrude rightward. This structure is beneficial to the miniaturization of the developing cartridge 1.

[0071] [Right end cap]

[0072] 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 provided 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 damage to the acting component 63 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] [Guide paper board]

[0074] When the developing cartridge 1 is working, 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 guide paper board 2d disposed below the housing 2, as Figure 1C shown, the guide paper board 2d has a continuous surface that extends substantially along the first direction and the second direction. Preferably, the surface of the guide paper board 2d is a smooth surface. More preferably, along the first direction, the surface of the guide paper board 2d is a flat surface, and along the second direction, the surface of the guide paper board 2d is a plurality of adjacent flat surfaces, and each two adjacent flat surfaces intersect at a line parallel to the first direction.

[0075] In practice, to prevent the leakage of the developer, as Figure 1B shown, along the first direction, the developing cartridge 1 further includes a first seal 39 located at two longitudinal ends of the developing member 31, and as Figure 3As shown, along the second direction, the developing cartridge further includes a second seal 38 and a third seal 37, at least a part of which is located in front of the developing member 31. The first seal 39 is preferably a felt / sponge for sealing at the longitudinal ends of the developing member 31. The second seal 38 is preferably a sheet seal for contacting and sealing the circumferential surface of the developing member 31. The third seal 37 is preferably a sponge for contacting and sealing the circumferential surface of the developing member 31.

[0076] Existing, the first seal 39, the second seal 38 and the third seal 37 are all combined with the housing 2 by pasting double-sided tape on one side. On the one hand, this method is not conducive to automated production, and the first seal 39 located at the two longitudinal ends of the developing member will be subjected to a large tensile force, resulting in the first seal being torn apart; on the other hand, the installation accuracy of this method is relatively low, resulting in a poor sealing effect. The present utility model realizes the precise combination of the first seal 39 / second seal 38 and the housing 2 by injecting an adhesive on the side of the first seal 39 / second seal 38 facing the housing. As Figure 1C shown, two injection ports 2e are further provided below the housing 2, and each injection port 2e is connected to at least one of the first seal 39 and the second seal 38. In this way, the adhesive injected through the injection port 2e can smoothly reach the side of the first seal 39 and / or the second seal 38 facing the housing 2. The method of injecting the adhesive through the injection port 2e can not only increase the bonding strength between the seal and the housing 2, but also effectively fill the gaps between the first seal 39, the second seal 38 and the third seal 37 and the gaps between each seal and the housing 2. In addition, the method of injecting the adhesive through the injection port 2e can also enable the developing cartridge 1 to be automatically produced. Preferably, along the first direction, the paper guide plate 2d is located between the two injection ports 2e to prevent the paper guide plate 2d from blocking the injection ports 2e. Further, along the first direction, the paper guide plate 2d is located between the conductive member 26 and the chip assembly 11 to prevent the chip assembly 11 from being affected by the conductive member 26.

[0077]

Driving Force Transmission Assembly

[0078] 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. When the stirring member driving member 44 is provided, the driving force transmission component 4 further includes an idle pulley 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 idle pulley 45, and then the stirring member driving member 44 transmits it to the detecting device 6. 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 idle pulley 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 mode 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 a rod arranged to be rotatable around a third axis L3 parallel to the first direction, including 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]

Detecting Device

[0081] The detecting device 6 includes a driving component 61 arranged at the driving end, an acting component 63 arranged at the detecting end, and a transmission member 62 located between the driving component 61 and the acting component 63. After receiving the driving force, the driving component 61 drives the transmission member 62 to move in a direction not perpendicular to the first direction, thereby forcing the acting component 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 detecting 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 detecting end is simplified. When the developing cartridge is assembled, only the assembly of the driving end needs to be focused on.

[0082] [Driving Component]

[0083] The driving component 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. For exampleFigure 4B As shown, along the first direction, at least the part of the counting member 613 (such as the protrusion described below) for interacting with the transmission member 62 is closer to the housing 2 / the left surface 21 / the right surface 22 than the driving member 612 and / or the stirring member driving member 44. Preferably, the entire counting member 613 is closer to the housing 2 / the left surface 21 / the 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 / the left surface 21 / the right surface 22 than the idler gear 45 / the 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.

[0084] [Cut-off of the driving force of the driving assembly]

[0085] The counting member 613 and the driving member 612 can be integrally formed or separately formed. After the detection is completed, the separation mechanism provided in the developing cartridge 1 makes 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 way of forcing the entire counting member 613 to move along the first direction or the way of the entire counting member 613 translating can be adopted to make the counting member 613 disengage from the driving 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, it can be that the counting member 613 disengages from the driving member 612, but the driving member 612 does not disengage from the driving source, or it can also be that the counting member 613 and the driving member 612 as a whole disengage from the driving source; in some embodiments, regardless of whether the counting member 613 and the driving member 612 are integrally formed, 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 driving source and receives the driving force. When the detection is completed, the toothless part of the driving member 612 faces the driving source and does not receive the driving force. The toothless part is a kind of separation mechanism.

[0086] 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 of 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.

[0087] When observed 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 between 5.5 mm and 6.5 mm. Especially in a structure where there are multiple gears arranged 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 may lead to 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 lead to the failure of the detection device 6 to detect.

[0088] When both the driving force receiving member 41 and the driving member 612 are set as gears, the gear tooth number ratio between the two ranges from 0.7 to 1.3, preferably from 0.8 to 1.1. In the solution where the transmission member 62 adopts a translation scheme, this tooth number ratio is conducive to the miniaturization setting at the end of the toner cartridge and improves the transmission accuracy.

[0089] Method 1

[0090] When the counting member 613 and the driving member 612 are formed separately, the separation mechanism includes an elastic pushing member 611, a guiding protrusion 613h provided on the counting member 613, and a groove 615 cooperating with the guiding protrusion 613h. The counting member 613 rotates around a cylinder 614 provided on the housing 2. The groove 615 is arranged in the circumferential direction of the cylinder 614. One end of the elastic pushing member 611 abuts against the counting member 613, and the other end abuts against the left end cover 27. During the detection process, the guiding protrusion 613h is not opposite to the groove 615, and the elastic pushing member 611 is in an elastically deformed state. When the detection is completed, the guiding protrusion 613h is opposite to the groove 615. Under the action of the elastic pushing member 611, along the first direction, the counting member 613 is pushed to a position separated from the driving member 612. At this time, the counting member 613 is pushed to a position closer to the housing 2, and the position of the driving member 613 relative to the housing 2 does not change. Therefore, even if the driving member 613 is set as a full-tooth gear, the counting member 613 will not be driven by the continuously rotating driving member 613.

[0091] Method 2

[0092] Similar to Method 1, in this method, one end of the elastic pushing member 611 abuts against the driving member 612, and the other end abuts against the left end cover 27. During the detection process, the elastic pushing member 611 is in an elastically deformed state. When the detection is completed, the elastic pushing member 611 releases its elastic force so that the guiding protrusion 613h is opposite to the groove 615. The counting member 613 and the driving member 612 as a whole are pushed along the first direction to a position closer to the housing 2. At this time, the driving member 612 is disengaged from the driving source, and the counting member 613 is no longer driven and remains stationary.

[0093] In the present embodiment and Embodiment 1, the elastic pushing member 611 is configured as a compression spring. Alternatively, the elastic pushing member 611 can also be configured as a tension spring. At this time, one end of the tension spring is connected to the housing 2, and the other end is connected to the counting member 613 or the driving member 612.

[0094] Embodiment 3

[0095] As described above, the separating mechanism can also be a toothless gear provided on the driving member 612. In some other embodiments, the separating mechanism can also be a pair of magnets. During the detection process, no magnetic force is generated between the pair of magnets. When the detection is completed, an attractive force or a repulsive force is generated between the pair of magnets, causing the counting member 613 and the driving member 612 to be separated from each other / disengaged, or the counting member 613 and the driving member 612 as a whole to be disengaged from the driving source.

[0096] Specifically, a first magnet is installed on the housing 2, and a second magnet is installed on the counting member 613. A repulsive force is generated between the pair of magnets. During the detection process, the pair of magnets face each other, and the counting member 613 can be combined with the driving member 612, or the counting member 613 and the driving member 612 as a whole can be kept combined with the driving source. When the detection is completed, the repulsive force disappears, and under the action of the elastic pushing member 611, the counting member 613 and the driving member 612 are separated from each other / disengaged, or the counting member 613 and the driving member 612 as a whole are disengaged from the driving source.

[0097] Alternatively, the first magnet is installed on the left end cover 27, and the second magnet is still installed on the counting member 613. An attractive force is generated between the pair of magnets, and this attractive force is greater than the elastic force of the elastic pushing member 611. During the detection process, the counting member 613 can be driven by the driving member 612. When the detection is completed, the pair of magnets are no longer opposite, and the attractive force between them disappears or decreases. Under the action of the elastic pushing member 611, the counting member 613 and the driving member 612 are separated from each other / disengaged. Similarly, when the second magnet is installed on the driving member 612, when the detection is completed, the counting member 613 and the driving member 612 as a whole are disengaged from the driving source.

[0098] When the detection device 6 is provided with an elastic reset member 67, one end of the elastic reset member 67 abuts against the transmission member 62, and the other end abuts against the housing 2. It can also be provided between the acting component 63 and the housing 2. The elastic reset member 67 can be a compression spring or a tension spring. In the above implementation, the elastic force applied by the elastic pushing member 611 is greater than the elastic force of the elastic reset member 67. When the elastic pushing member 611 pushes the counting member 613 and / or the driving member 612, the moving speed of the transmission member 62 will be increased. Eventually, the rotating speed of the detected member 9 is also increased, thus forming a phenomenon that the detected member 9 is accelerated.

[0099] Embodiment 4

[0100] In this embodiment, the separation mechanism no longer has an elastic push member. Figure 5B As shown, the left end cover 27 is provided with a guide path 271 and a forced push surface 272 located in the groove-shaped guide path, and the forced push surface 272 is set as an inclined surface, such as Figure 5C As shown, the counting member 613 also includes a guide block 613i arranged at the coupling portion 613b. During the detection process, the guide block 613i is guided by the guide path 271. When the detection is about to be completed, the guide block 613i abuts against the forced push surface 272. As a result, the counting member 613 and the driving member 612 gradually disengage. In the process of the counting member 613 and the driving member 612 disengaging, the inclined forced push member 272 accelerates the rotation speed of the counting member 613. Correspondingly, the movement speed of the transmission member 62 to the right / detection end is also accelerated. Finally, the rotation speed of the detected member 9 is also accelerated, thereby forming a phenomenon that the detected member 9 is accelerated.

[0101] Method 5

[0102] In the above-mentioned method three, the acceleration process of the transmission member 62 / detected member 9 is achieved by the elastic pushing member 611 releasing the elastic force. However, alternatively, the acceleration process of the transmission member 62 / detected member 9 can also be achieved solely by the elastic reset member 67 releasing the elastic force. For example, when the transmission member 62 moves downward from the protrusion of the counting member 613, the elastic reset member 67 releases the elastic force and forces the transmission member 62 / counting member 613 to be accelerated.

[0103] [Structure of counting pieces]

[0104] The multiple protrusions include a positioning protrusion 613d, a first toggle protrusion 613e and a second toggle protrusion 613f which are 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. The number of the toggle protrusions may be increased or decreased according to the detection requirements of the detection device. The counting member 613 provided with the first toggle protrusion 613e and the second toggle protrusion 613f is taken as an example for explanation below.

[0105] During the detection process, the first toggle protrusion 613e and the second toggle protrusion 613f contact the transmission member 62 in sequence, thereby forcing the transmission member 62 to move to the right / detection end. Figure 6BAs shown, each toggle protrusion includes a rising surface 613e1 / 613f1, a retaining surface 613e2 / 613f2 and a descending surface 613e3 / 613f3. As the counting member 613 rotates, when the rising surface 613e1 / 613f1 contacts the transmission member 62, the transmission member 62 will be gradually pushed toward the right / detection end until the retaining surface 613e2 / 613f2 contacts the transmission member 62. Finally, when the retaining surface 613e2 / 613f2 disengages from the transmission member 62, the transmission member 62 disengages from the corresponding toggle protrusion and contacts the flat portion 613g.

[0106] The length of the rising surface 613e1 / 613f1 from the bottom to the top can determine the distance that the transmission member 62 moves to the right / detection end, and the two are proportional. When the height of the toggle protrusion is constant, the larger the angle a1 / a2 between the rising surface 613e1 / 613f1 and the flat portion 613g, the shorter the stroke of the transmission member 62, and the faster the transmission member 62 is pushed. Preferably, the retaining surface 613e2 / 613f2 is parallel to the flat portion 613g, and the larger the size of the retaining surface 613e2 / 613f2, the faster the transmission member 62 is retained. The longer the state time; as mentioned above, the flat portion 613g is located between the two toggle protrusions. Therefore, the larger the size of the flat portion 613g, the longer the time interval between two pushes of the transmission member 62. It can be seen that the detection requirements of the equipment are different, and the length of the rising surface 613e1 / 613f1 from the bottom to the top, the angle a1 / a2 between the rising surface 613e1 / 613f1 and the flat portion 613g, the size of the retaining surface 613e2 / 613f2 and the size of the flat portion 613g may be different. Designers can make adjustments according to detection requirements.

[0107] like Figure 6BAs shown, in some embodiments, the lengths of the first flat portion 613g1 and the second flat portion 613g2 can vary between 1 mm and 10 mm. Preferably, the lengths of the first flat portion 613g1 and the second flat portion 613g2 are 3 mm - 4 mm; the height of the holding surface 613e2 / 613f2, i.e., the value of the descending surface 613e3 / 613f3, can vary between 1 mm and 10 mm, preferably 3 mm - 6.5 mm. The height of the holding surface 613e2 of the first toggle protrusion is more preferably 4.5 mm - 6 mm, and the height of the holding surface 613f2 of the second toggle protrusion is more preferably 4.5 mm - 6.5 mm; the angle a1 between the rising surface 613e1 of the first toggle protrusion and the flat portion 613g can vary between 5° and 85°, preferably between 25° and 65°, and more preferably, the angle a1 varies between 30° and 35°. The angle a2 between the rising surface 613f1 of the second toggle protrusion and the flat portion 613g can vary between 10° and 90°, preferably, the angle a2 varies between 35° and 75°, and more preferably, the angle a2 varies between 60° and 70°. Specifically, in the rotation direction of the counting member 613, the first toggle protrusion 613e is located downstream of the second toggle protrusion 613f. In the structure where the toggle protrusion is used to push the transmission member to move in the first direction, through the detailed study of the height, inclination angle of the toggle protrusion, and the distance between adjacent toggle protrusions, it can be ensured that the cooperation between the toggle protrusion and the transmission member is smoother, the transmission is more stable, and the detection effect is better.

[0108] As Figure 6C shown, in some other embodiments, the counting member 613 is provided with three toggle protrusions. The structures of two of the toggle protrusions are the same. For example, the structures of these two toggle protrusions are the same as the structure of the above-mentioned first toggle protrusion 613e, and are respectively referred to as the first toggle protrusion and the second toggle protrusion in this embodiment. The structure of the other toggle protrusion is different from that of the first toggle protrusion 613e. For example, it is the same as the structure of the above-mentioned second toggle protrusion 613f and is referred to as the third toggle protrusion in this embodiment. At this time, the counting member 613 will form three flat portions, namely, the first flat portion 613g1 located between the positioning protrusion 613d and the first toggle protrusion, the second flat portion 613g2 located between the first toggle protrusion and the second toggle protrusion, and the third flat portion 613g3 located between the second toggle protrusion 6 and the third toggle protrusion. Specifically, in the rotation direction of the counting member, the first toggle protrusion and the second toggle protrusion are located downstream of the third toggle protrusion, that is, during the detection process, the transmission member 62 touches the first toggle protrusion, the second toggle protrusion, and the third toggle protrusion in sequence.

[0109] During the detection process of the detection device 6, the effective detection angle a5 range of the counting member 613 is 200° - 320°, preferably 250° - 280°. By limiting a5 within the above range, it can be ensured that within the detection cycle of the detection device 6, the transmission member 62 can be toggled by the counting member 613 at least twice. According to the different models of the developing cartridge 1, the number of times of the at least toggling is three or more. The detection accuracy of the detection device 6 can be precisely controlled, and at the same time, it is beneficial to realize the miniaturization of the counting member 613.

[0110] Based on the above structure and movement process of the counting member 613, the transmission ratio range between the driving force receiving member 41 and the counting member 613 varies between 0.05 - 0.5, preferably 0.1 - 0.2. Setting the transmission ratio within the above range has the following beneficial effects:

[0111] This setting is beneficial for the transmission member 62 to receive a stable driving force from the counting member 613, and will not cause problems such as accelerated wear between components, excessive stress concentration, and even breakage of the transmission member 613 due to too fast rotation speed. At the same time, this setting will not cause the counting member 613 to rotate too slowly, resulting in the detection device 6 not being able to interact with the detected member 9 in a timely manner, which not only wastes electricity, leads to low detection efficiency, but also is very likely to cause the detection failure of the detection device 6. [Structure and installation of the transmission member]

[0112] The transmission member 62 includes a forced push portion 621 at the driving end, a transmission portion 623 at the detection end, and a movement portion 622 between the forced push portion 621 and the transmission portion 633. Further, the transmission member 62 further includes a reset member 67. When the transmission member 62 is pushed to the right / detection end, the reset member 67 accumulates a 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 is driven by the detected member 9 to drive the action component 63, and then the action component 63 forces the transmission member 62 to reset.

[0113] As Figure 3 shown, along the third direction, the housing 2 includes an upper housing 2a located above and a lower housing 2b located below. The developer chamber 10 is located between the upper housing 2a and the lower housing 2b. As Figure 2 shown, the guiding groove 25 is provided above the upper housing 2a, and the guiding groove 25 is exposed upward. The transmission member 62 is movably installed in the guiding groove 25. In this way, the transmission member 62 will not affect the developer during movement, and the leakage of the developer is also avoided.

[0114] The developing cartridge 1 further includes a covering member 24 for preventing the transmission member 62 from falling off. The covering member 24 covers the guiding groove 25 from above. On the one hand, the transmission member 62 will not fall off from the guiding groove 25, protecting the transmission member from external touch; on the other hand, the aesthetic appearance of the developing cartridge can be improved. The covering member 24 can be combined with the housing 2 by means of snap connection, welding, bonding, magnetic attraction, etc.

[0115] The following describes the installation structure of the transmission member 62 and the changes in the movement mode.

[0116] Variation 1

[0117] As Figure 7 shown, the transmission member 62 is integrally plate-shaped, and the covering member 24 is at least a pair of intermittent protrusions provided on the upper housing 2a. The pair of intermittent protrusions 24 are arranged opposite to each other in the second direction. This relative arrangement includes the cases where, in the second direction, the pair of intermittent protrusions 24 are directly opposite and staggeredly opposite. The guiding groove 25 is located between the pair of spaced protrusions 24; further, each intermittent protrusion 24 also extends a limiting portion towards the guiding groove 25 in the second direction to prevent the transmission member 62 from falling off.

[0118] Variation 2

[0119] As Figure 8A shown, the transmission member 62 is arranged to be rotatable about an axis L6 that is not perpendicular to the third direction. Preferably, the rotation axis L6 of the transmission member 62 is parallel to the third direction. At least a pair of guiding plates 252 protrude upward from the housing 2a. The guiding groove 24 is located between the pair of guiding plates 25. Similarly, in the second direction, the pair of guiding plates 252 can be either directly opposite or staggeredly arranged. The rotating shaft 625 is provided on the moving portion 622, and the covering member 24 covers the rotating shaft 625 to prevent the transmission member 62 from falling off.

[0120] When the forced push portion 621 receives a forced push force, the transmission member 62 as a whole swings around the rotation axis L6. During this swinging process, the transmission portion 623 directly or indirectly interacts with the detected member 9; as Figure 8B shown, along the first direction, the end point of the transmission member 62 at the detection end is P. The dotted line in the figure shows the position of the transmission member 62 after swinging. Before swinging, the transmission member 62 is in the first position. After swinging, the transmission member 62 is in the second position. Taking the surface 2a2 of the housing 2 / upper housing 2a at the detection end as a reference, it can be seen that when the transmission member 62 is in the first position, the end point P has a distance h1 from the surface 2a, and when the transmission member 62 is in the second position, the end point P has a distance h2 from the surface 2a. The h1 and h2 are not equal. That is to say, during the detection process of the detection device 6, along the first direction, the transmission member 62 still has a movement distance.

[0121] Further, to reduce the friction when the transmission member 62 moves, the developing cartridge further includes a plurality of ribs 251 disposed in the guiding groove 25. Along the second direction, the plurality of ribs 251 are arranged at intervals. In this way, the contact area between the transmission member 62 and the guiding groove 25 is reduced, and the friction between the two is also reduced. It is achievable that the ribs 251 can also be disposed on the transmission member 62. Smearing lubricating powder or replacing with a material having a lower coefficient of friction (such as POM material) on the guiding groove 25 or the transmission member 62 can also reduce the friction between the two, improving the transmission efficiency and detection accuracy.

[0122] [Structure of the acting component]

[0123] The acting component 63 is arranged to be rotatable about the axis L5. During the rotation process, the acting component 63 interacts with the component to be detected 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. In the following text, it is taken as an example that the axis L5 is perpendicular to the first direction.

[0124] The acting component 63 includes a rotating portion 631, an acting protrusion 632, and a passive portion 633 extending from the rotating portion 631. Along the direction perpendicular to the rotation axis L5, the acting protrusion 632 is arranged in a non-linear extension manner. It can directly extend from the rotating portion 631 or extend from a connecting portion 636 connected to the rotating portion 631. For example Figure 10A As shown, the acting protrusion 632 is generally claw-shaped, and a groove / avoidance portion 6323 is provided in the acting protrusion 632 and recessed in a direction opposite to the rotation direction r3 of the acting component 63. As Figure 10B and Figure 10C shown, when the acting protrusion 632 rotates with the rotating portion 631, the acting portion 6324 of the acting protrusion 632 will directly contact the surface 921 of the second rod 92 facing the acting protrusion 632 (as Figure 12B shown), instead of the acting 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 / transmission member 62 / acting component 63 side.

[0125] In the developing cartridge where the driving component 4 is entirely located at the driving end, when the developing cartridge is working, the torque received at the driving end is relatively large, which may cause the overall developing cartridge to show that the right side / detection end is higher than the left side / driving end. During the detection process, the acting protrusion may contact different positions of the detected part 9, resulting in detection errors. Therefore, the acting part 6324 of the acting protrusion 632 for abutting against the second rod 92 in this embodiment needs to be set closer to the free end 923 of the second rod 92. Thus, it can be seen that during the working process of the acting component 63, in the third direction, when the contact position of the acting part 6324 with the second rod 92 is higher than the predetermined position, by cutting off a part of the acting protrusion 632, the contact position of the acting part 6324 with the second rod 92 can be returned to the predetermined position, as Figure 10A and Figure 10B shown, two surfaces 6321 / 6322 with different heights are formed above the acting protrusion 632, and there is a height difference between them. In this way, the contact position of the acting protrusion 632 with the second rod 92 can be moved downward. Accordingly, when the acting protrusion 632 is set 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 achieved.

[0126] As Figure 10D shown, along the radial direction of the rotating part 631, the acting protrusion 632 has the farthest point M. With this farthest point M as a reference, the angle a4 that the acting protrusion 632 in this embodiment can rotate is shown. The line of sight in the figure represents the position where the acting protrusion 632 is not touching the second rod 92, and the dotted line represents the position where the acting protrusion 632 is located when the second rod 92 is toggled to the predetermined position. The angle a4 can vary within the range of 20° - 70°, preferably 30° - 45°.

[0127] Figure 11A and Figure 11B show another structure of the acting protrusion 632. Different from the above embodiment, in this embodiment, an inclined surface 632a and a flat surface 632b are provided on the side of the acting protrusion 632 facing the second rod 92. The groove / avoidance part 6323 extends in the third direction within the flat surface 632b and the inclined surface 632a. When the acting protrusion 632 contacts the second rod 92, similarly, the edge 922 will not contact the acting protrusion 632, and the acting part 6324 directly contacts the surface 921.

[0128] In one implementation, the passive part 633 is in shaft - hole fit with the transmission part 62. When the transmission part 62 reciprocates in the first direction, the passive part 633 and the transmission part 62 can move relative to each other, that is, the size of the hole is larger than the size of the shaft. As Figure 7 shown, the passive part 633 is set as a shaft, and a hole 6231 is provided on the transmission part 62.

[0129] AsFigure 9B As shown, the hole 6231 is set as a square hole, and the passive part 633 is a cylinder. Specifically, the diameter of the cylinder 633 varies between 1 mm and 8 mm, preferably between 2.5 mm and 3.5 mm. Along the first direction, the size of the hole 6231 varies between 2 mm and 8 mm, preferably between 3 mm and 3.5 mm. Along the second direction, the size of the hole 6231 varies between 2 mm and 10 mm, preferably between 4 mm and 5 mm. It is achievable that the hole 6231 can also be a notch or a groove. Preferably, along the first direction, the size of the hole 6231 is the same as the diameter of the cylinder 633, which can avoid the existence of virtual positions. Along the second direction, the size of the hole 6231 is larger than the diameter of the cylinder 633, so as to reserve a moving space for the cylinder 633. If the size of the shaft is too small, not only its strength is insufficient and it is easy to break; if the size is too large, it will occupy a large space, which is not conducive to the miniaturization of the developing cartridge.

[0130] The following combines Figure 13 , Figure 14A , Figure 14B and Figure 15 , Figure 16A , Figure 16B to describe a deformation embodiment of the acting component 63.

[0131] Deformation 1

[0132] As Figure 13 shown, the acting component 63 includes a toggling member 634 that can rotate around the rotation axis L5 and a moving member 64 for driving the toggling member 634. The moving member 64 includes a base 641 and a moving part 642 that can move relative to the base 641. Among them, the moving part 642 is set to be able to rotate only in one direction. The toggling member 634 includes a central shaft 6340 and a first toggle rod 6341, a second toggle rod 6342 and a ratchet 6343 combined with the central shaft. The ratchet 6343 is used to be pushed by the moving part 642. Preferably, the ratchet 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 in other words, the first toggle rod 6341 and the second toggle rod 6342 have a height difference. In this way, the positions of the first toggle rod 6341 and the second toggle rod 6342 for toggling the detected part 9 are different.

[0133] During the detection process, the transmission part 623 moves towards the right / detection end and pushes the movable part 64. Further, the movable part 642 pushes the ratchet wheel 6343 to rotate. Then, the first lever 6341 or the second lever 6342 abuts against the second rod 92. When the transmission part 623 no longer pushes the movable part 64, the movable part 64 is pushed by a component such as an elastic part to reset. As Figure 14A shown, the first lever 6341 contacts the surface 921 of the second rod at point Q1. As the ratchet wheel 6343 is toggled, the part to be detected 9 is pushed to rotate around the rotating part 93 in the direction shown by r until the first lever 6341 disengages from the second rod 92. As the ratchet wheel 6343 continues to rotate, the second lever 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 part 93 than point Q1. When the rotation speed of the ratchet wheel 6343 remains unchanged, the part to be detected 9 will rotate faster under the push of the second lever 9342, thus forming a phenomenon that the part to be detected 9 is accelerated.

[0134] For the movable part 64, after the movable part 642 pushes the ratchet wheel 6343, during the process of the elastic part forcing the movable part 64 to reset, the movable part 642 is supported by the ratchet wheel 6343 and rotates. In this way, the movable part 643 can enter the position for pushing the ratchet wheel 6343 next time. In some embodiments, the movable part 64 is connected to the transmission part 623 and can move along with the movement of the transmission part 623.

[0135] Variant Two

[0136] In this variant embodiment, the acting component 63 is set as a rotating part that can rotate around an axis not perpendicular to the first direction, including a central shaft 635, a guiding path 6351 arranged on the central shaft 635, a guiding inclined surface 6352 located in the guiding path, and a lever 6353 connected to the central shaft 635. The transmission part 62 is still set as a component that can reciprocate along a direction not perpendicular to the first direction. The transmission part 623 of the transmission part 62 is set as a component that can be guided by the guiding path 6351. Preferably, the guiding path 6351 is a groove arranged on the central shaft 635, and the guiding inclined surface 6352 is arranged in the groove 6351.

[0137] As Figure 16A 、 Figure 16B 、 Figure 17A and Figure 17BWhen the transmission member 62 moves to the right / detection end, the transmission part 623 presses the guide slope 6352, and the rotating member 63 is forced to rotate around its axis in the direction indicated by r1. At the same time, the lever 6353 pushes the second rod 92 of the detected member 9. When the transmission member 62 moves to the left / driving end, the transmission part 623 no longer presses the guide slope 6352. Under the action of an elastic member, the rotating member 63 is reset, and the lever 6353 no longer pushes the second rod 92.

[0138] Deformation Three

[0139] In this modified embodiment, the transmission member 62 directly moves the detected member 9, or in other words, the action component 63 is formed integrally with the transmission member 62. In this case, the detection device 6 may also be considered to no longer have the action component 63. Figure 18 , Figure 19A and Figure 19B As shown, the transmission part 623 of the transmission member is provided with an arc surface / inclined surface 6232 . As the transmission member 62 moves to the right / detection end, the arc surface / inclined surface 6232 contacts the second rod 92 of the detected member and pushes the detected member 9 to rotate around the rotating part 93 .

[0140] The arc surface / inclined surface 6232 has a first end 6232a and a second end 6232b. Along the first direction, the first end 6232a is farther away from the moving part 622 / forced pushing part 621 than the second end 6232b. In this way, when the transmission member 62 moves to the right / detection end, the transmission part 623 / arc surface / inclined surface 6232 can smoothly move the second rod 92; when the transmission member 62 is reset to the left / driving end, the transmission part 623 / arc surface / inclined surface 6232 is still in contact with the second rod 92, so that the second rod 92 can be reset smoothly.

[0141] Transformation 4

[0142] In this variant embodiment, the action component 63 and the transmission member 62 are connected in the form of a gear and a rack. Figure 20A , Figure 20B , Figure 21A and Figure 21B 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 moved. [Reset of the counting member]

[0143] like Figure 5B , Figure 5CAs shown, a first indicating portion 273 is provided on the left end cover 27, a second indicating portion 6121 is provided on the driving member 612, and a third indicating portion 613d1 is provided on the counting member 613. Before the detection device 6 starts detection or after the detection device 6 is reset, along the first direction, the first indicating portion 273, the second indicating portion 6121, and the third indicating portion 613d1 are always substantially aligned. The shapes of the first indicating portion 273, the second indicating portion 6121, and the third indicating portion 613d1 can be, for example, protrusions, grooves, dentate bodies, arrows, etc., as long as they can play an indicating role.

[0144] For the convenience of resetting the counting member 613, a force-applying portion 613j is further provided on the positioning protrusion 613d of the counting member 613. For example, the force-applying portion 613j is a groove provided on the positioning protrusion 613d or a protrusion provided on the positioning protrusion 613d, and at least a part of the force-applying portion is exposed. When the detection device needs to be reset, the rotating action assembly 63 is rotated to make the transmission member 62 rotate around its axis. At the same time, a force is applied to the force-applying portion 613j so that the first indicating portion 273, the second indicating portion 6121, and the third indicating portion 613d1 are aligned along the first direction.

[0145] Furthermore, to prevent the transmission member 62 from moving unnecessarily, a limiting portion is further provided on the positioning protrusion 613d. Preferably, the limiting portion coincides with the third indicating portion 613d1 to simplify the structure of the counting member 613. More preferably, the limiting portion is a limiting groove.

[0146] Even further, as Figure 5A and Figure 22 shown, at the driving end, the end face (left end face) of the upper housing 2a is not a whole plane. Along the first direction, the left end face of the upper housing 2a includes a first left end face 2L1 and a second left end face 2L2. Among them, the second left end face 2L2 is closer to the detection end than the first left end face 2L1. An exposed portion 2c will be formed between the first left end face 2L1 and the second left end face 2L2. Along the first direction, the exposed portion 2c is located between the right end 274 of the end cover 27 and the second left end face 2L2. At least a part of the counting member 613 is exposed through this exposed portion. On the one hand, the user can observe whether the detection device has been reset through the exposed portion 2c. On the other hand, the exposed portion 2c also provides a space for the counting member 613 to move in the direction closer to the housing 2, so that the counting member 613 does not have to be arranged further to the left, which can play a role in reducing the size of the developing cartridge in the first direction.

[0147] Preferably, the exposed portion 2c is exposed upward, which is more conducive to the user's observation; further, the force - applying portion 613i of the counting member 613 is also exposed through the exposed portion 2c, and the end - cover 27 does not need to be additionally provided with an opening for resetting the counting member 613. The user can apply a force to the force - applying portion 613i through the exposed portion 2c to reset the detection device 6; furthermore, the protrusions 613d / 613f of the counting member 613 are arranged to face or face away from the housing 2, that is, the counting member 613 is located between the left end - cover 27 and the housing 2. In this way, the protrusions 613d / 613f can be effectively protected by the left end - cover 27, the driving member 612, and the housing 2.

[0148] [Delay movement of the counting member]

[0149] In some embodiments, the detected member 9 is arranged such that it starts to be toggled 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 have a delay, that is, the driving force received by the driving - force receiving member 41 is not immediately transmitted to the counting member 613.

[0150] It is achievable that along the rotational direction of the counting member 613, there is a predetermined distance 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 is not 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 achieved.

[0151] As Figure 23 shown, taking the driving member 612 being driven by the stirring - member gear 44 and the counting member 613 and the driving member 612 being integrally formed as an example for description. The stirring - member gear 44 is arranged 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. Among them, 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 facing the driving member 612 and transmitting the driving force to the driving member 612.

[0152] 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.

[0153] 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.

[0154] 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 .

[0155] [Acceleration of the test piece]

[0156] 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.

[0157] Method 1

[0158] Combine the following Figure 24 , Figure 25A and Figure 25BDescribe another way to accelerate the counting part 613.

[0159] In this embodiment, still taking the counting part 613 and the driving part 612 being integrally formed as an example, the driving part 612 is set as a toothless gear. Further, the driving part 612 also includes an arc surface 6124 coaxially arranged with the toothless gear 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 part outside the driving part 612.

[0160] As Figure 25A 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.

[0161] Method 2

[0162] 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 toothless gear. 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 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.

[0163] Example 2

[0164] In this embodiment, the same components as those in the above embodiment are numbered the same.

[0165] As Figure 26A and Figure 26BAs 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. This design is beneficial to reducing the size of the developing cartridge in the third direction and ensuring that the developer chamber 10 has a sufficiently large volume.

[0166] 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 formed integrally or separately 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.

[0167] 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.

[0168] The pushed portion 621 receives the pushing force, causing the pushed member 620 to rotate in 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 in the rotation direction r7. Furthermore, the acting protrusion 632 toggles the second rod 92. At this time, the reset member 64 is compressed or stretched to store 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. Furthermore, the acting protrusion 632 no longer toggles the second rod 92.

[0169] Further, the driving member 612 and the counting member 613 may be formed separately or integrally. In this embodiment, a cam may be used to replace the counting member 613, and only one driving member 612 is provided.

[0170] 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.

[0171] Example 3

[0172] On the basis of Embodiment 2, 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.

[0173] As Figure 27 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 2 are set integrally. 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 may 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.

[0174] 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 excessive deviation in the second direction and being unable to move along the correct direction, so that the acting protrusion 632 cannot interact with the second rod 92 or the moment when the acting protrusion 632 touches the second rod 92 is incorrect.

[0175] Further, the forced - pushing member 620 and the moving part 622 can be combined by means of shaft - hole cooperation. 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.

[0176] Further, a crank - connecting rod structure is formed between the forced - pushing member 620 and the moving part 622 in this embodiment.

[0177] On the basis of the above - mentioned embodiment, 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.

[0178] As Figure 28A and Figure 28B shown, the transmission member 62 includes a pushed member 620 located at the driving end, a transmission portion 623 located at the detection end, and a moving portion 622 located between the pushed member 620 and the transmission portion 623; the acting protrusion 632 is provided on the side of the transmission portion 623 close to the second rod 92. The acting protrusion 632 can be an additionally provided component or the end of the transmission portion 623 close to the second rod 92.

[0179] Further, the pushed member 620, the moving portion 622, and the transmission portion 623 are formed separately from each other in pairs, and the combination manner among the three is the same as that in the second embodiment, which will not be elaborated here. The difference is that in this embodiment, the transmission member 62 further includes a guiding groove 25 provided on the housing 2. The guiding groove 25 is located between a pair of guiding plates 252. The pair of guiding plates 252 protrude upward from the housing 2. In the second direction, the pair of guiding plates 252 can either directly face each other or be arranged in a staggered manner.

[0180] Furthermore, the forced pusher 620 is configured to be rotatable about a rotation axis L11. Preferably, the rotation axis L11 is not perpendicular to the third direction. More preferably, the rotation axis L11 is parallel to the third direction. When the driving member 612 starts to rotate, the forced pusher 620 is configured to rotate in the direction shown by r8. The moving part 622 is configured to be movable in the first direction, and the transmission part 623 is configured to be movable in the first direction along the guiding groove 25. Further, the forced pusher 620 is provided with an intermediate column 6201 and a main body 6202 arranged circumferentially / radially along the intermediate column 6201. The forced pushing part 621 protrudes radially from the intermediate column 6201 or axially from the main body 6202 for receiving the forced pushing force. At the same time, a plurality of protrusions 620b arranged adjacent to the forced pushing part 621 can be used to receive the driving force to rotate the forced pusher 620 in the rotation direction r8, thereby driving the moving part 622 and the transmission part 623 to move in the first direction away from the detection end (one end 51 of the first direction), so that the acting protrusion 632 will not toggle the second rod 92. In this way, a time delay effect can be achieved. As the forced pusher 620 continues to rotate in the rotation direction r8, when the plurality of protrusions 620b no longer receive the driving force, the moving part 622 and the transmission part 623 are driven to move in the first direction towards the detection end (the other end 52 of the first direction), and the acting protrusion 632 toggles the second rod 92 and remains engaged with the second rod 92. Preferably, the forced pusher 620 is configured as a spur gear with missing teeth. In this way, the part without the plurality of protrusions 620b does not contact the driving member 612, so that the forced pusher 620 no longer rotates in the direction shown by r8. Subsequently, the reset member 64 will push the transmission member 62 to reset, or as the second rod 92 resets, the second rod 92 in turn pushes the transmission member 62 to reset. As the driving member 612 continues to rotate, the toggling part 4411 of the driving member 612 engages with the forced pushing part 621, causing the forced pusher 620 to rotate by an angle, thereby driving the moving part 622 and the transmission part 623 to move in the first direction away from the detection end (one end 51 of the first direction), so that the acting protrusion 632 leaves the second rod 92, that is to say, the second rod 92 is toggled again.

[0181] Furthermore, a crank - connecting rod structure is formed between the forced pusher 620 and the moving part 622 in this embodiment.

[0182] Example 5

[0183] On the basis of the above - mentioned embodiment, this embodiment will deform some structures of the transmission member 62. The same components in this embodiment and the above - mentioned embodiment are numbered the same.

[0184] Such as Figure 29A and Figure 29BAs shown, 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 a rotation axis L9, and the transmission portion 623 is arranged to be rotatable about a 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.

[0185] 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.

[0186] Different from the above embodiments, in this embodiment, the motion portion 622 is arranged 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. Further, one end of the flexible member 622 is connected to the pushed member 620, and the other end is connected to the transmission portion 623; preferably, the flexible member 622 does not need to be wound around the pushed member 620 or the transmission portion 623; the reset member 67 is used to reset the acting protrusion 632 for the next detection. Further, the transmission portion 623 is provided with a shaft body 623c extending axially towards the housing 2. The shaft body 623c is used to cooperate with the housing 2 to install the transmission portion 623. The reset member 67 in this embodiment is arranged to cooperate with the transmission portion 623. Further, the reset member 67 is a torsion spring. The torsion spring 67 is sleeved on the shaft body 623c. The torsion spring 67 has a first end 67a and a second end 67b. Among them, the first end 67a abuts against a clamping groove 623d provided on the transmission portion 623, and the second end 67b abuts against the housing 2. Further, the clamping groove 623d is radially recessed inward from the outer surface 623b of the transmission portion 623.

[0187] The pushed portion 621 receives the pushing force, causing the pushed member 620 to rotate in the direction shown by r6, thereby driving the motion portion 622 to pull the transmission portion 623 to rotate in the direction shown by r7 in the first direction, and further causing the acting protrusion 632 to toggle the second rod 92. At this time, the reset member 67 is compressed to accumulate the reset force. When the pushed portion 621 no longer receives the pushing force, the reset force of the reset member 67 causes the transmission portion 623 to rotate in the direction opposite to the direction shown by r7, thereby driving the motion portion 622 to pull the pushed member 620 to rotate in the direction opposite to the direction shown by r6 in the first direction, and at the same time causing the acting protrusion 632 to no longer toggle the second rod 92, and the acting protrusion 632 is reset.

[0188] In this embodiment, a flexible member is used as the moving part 622, 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.

[0189] In other 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.

[0190] Example 6

[0191] The same components in this embodiment as those in the above embodiments are numbered the same.

[0192] As Figure 30 shown, the transmission member 62 includes a transmission part 623 at the detection end and a moving part 622 connected to the transmission part 623. The transmission part 623 is arranged to be rotatable about the rotation axis L10. Preferably, the rotation axis L10 is not perpendicular to the third direction. More preferably, the rotation axis L10 of the transmission part 623 is parallel to the third direction. Similar to Embodiment Five, the moving part 622 in this embodiment is also set as a flexible member such as a flexible belt or a flexible rope. One end of the flexible member 622 in this embodiment 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. Therefore, the counting member 613 in this embodiment can also be regarded as the forced pusher 620 in the transmission member 62. In addition, the acting protrusion 632 can be set to one or more according to the detection needs. In this embodiment, three acting protrusions 632 are provided, including a first acting protrusion 632a, a second acting protrusion 632b, and a third acting protrusion 632c. Further, the acting protrusion 632 is integrally or separately formed with the transmission part 623.

[0193] During detection, the driving member 612 drives the counting member 613 to rotate in the direction shown by r5. The flexible member 622 is pulled and winds around the counting member 613, thereby driving the transmission part 623 to rotate in the direction shown by r7, and further causing the three acting protrusions 632 to sequentially touch the second rod 92. At the same time, the flexible member 622 wound around the transmission part 623 is released.

[0194] This embodiment can achieve the same technical effects as Embodiment Five, so it will not be elaborated here.

[0195] Example 7

[0196] The same components in this embodiment as those in the above embodiments are numbered the same.

[0197] As Figure 31A and Figure 31B 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. The pushed member 620 is configured to be rotatable about a rotation axis L9, and the transmission portion 623 is configured to be rotatable about a 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.

[0198] What is different between this embodiment and the above embodiment is that in this embodiment, the pushed member 620, the moving portion 622, and the transmission portion 623 are configured as a gear-rack structure. Further, the counting member 613 is configured as a gear rotatable about a rotation axis L8, the structure of the counting member 613 is simplified, and at the same time, the pushed member 620 is also configured as a gear structure and combined with the counting member 613. One end of the moving 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. What is the same as in Embodiment Six is that the acting protrusions 632 can be provided as one or more according to detection needs. In this embodiment, three acting protrusions 632 are provided, 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 moving portion 622 can also directly mesh with the counting member 613, so that the structure of the transmission member 62 can be simplified.

[0199] Further, a guide rod 25a is also provided in the guide groove 25 provided in the housing 2, thereby forming a groove 252 for guiding the movement of the moving portion 622.

[0200] 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 moving 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.

[0201] In this embodiment, the same components as those in the above embodiment are numbered the same.

[0202] As Figure 32As shown, different from the seventh embodiment, in this embodiment, the moving part 622 is arranged as a plurality of meshing gears. Preferably, in this embodiment, the moving part 622 includes nine meshing gears. Among them, the gear meshing with the counting part 613 can also be regarded as the forced pushing part 620.

[0203] During detection, the driving part 612 drives the counting part 613 to rotate along the direction of r5 (as Figure 31B shown), and transmits the driving force to the transmission part 623 through gear transmission, so that the three acting protrusions 632 touch the second rod 92 in sequence.

[0204] In the above embodiment, the direction of the rotation axis L9 of the forced pushing part 620 and / or the direction of the rotation axis L10 of the transmission part 623 can also be adjusted according to the design requirements. Generally, the rotation axis L9 and the rotation axis L10 are not perpendicular to the third direction respectively. Similarly, the rotation axis L9 of the forced pushing part 620 and the rotation axis L10 of the transmission part 623 in this embodiment are also not perpendicular to the third direction respectively.

[0205] In the above second to eighth embodiments, the driving force is no longer transmitted through the stirring part 33, which can reduce the load of the stirring part 33, thereby avoiding the breaking of the stirring part 33. Moreover, the forced pushing part and the moving part are formed separately. In this way, the strength of each component can also be increased, thereby avoiding deformation or transmission lag caused by the excessive length of a certain component in the first direction and insufficient strength. In addition, a flexible part with better stability is used as the moving part, thereby improving the durability and detection accuracy of the detection device.
