Description

Technical Field

[0001] The utility model relates to the field of electronic photographic imaging, in particular to a developing box which is detachably installed in an electronic photographic imaging device. Background Art

[0002] A developer cartridge is a container containing developer. When installed in an electrophotographic imaging device (hereinafter referred to as the "device"), the developer creates a desired image or text on an imaging medium using electrostatic imaging technology. To enable the device to obtain information such as the model of the developer cartridge, existing developer cartridges are equipped with a detection device that interacts with a detected component in the device. Furthermore, the developer cartridges are equipped with a conductive member for receiving power from the imaging device.

[0003] The conductive part includes a developing part power receiving portion for receiving power for the developing part in the developing box and a powder feeding part power receiving portion for receiving power for the powder feeding part in the developing box. The powder feeding part is arranged adjacent to the developing part. When the developing box is working, the powder feeding part supplies the developer toward the developing part, and the developing part transports the developer toward the photosensitive drum close to it, so that the electrostatic latent image formed on the surface of the photosensitive drum develops.

[0004] In order to simplify the structure of the developing box, a method has emerged in which the power receiving part of the developing element receives power and supplies it to the developing element or supplies it to the developing element and the powder feeding element at the same time. However, the use environment of the developing box is diverse. When the developing box is in a harsh environment of high temperature, high pressure or humidity, the charging performance of the developer itself will decrease, resulting in the developer not being effectively supplied from the surface of the developing element to the photosensitive drum, thereby reducing the development quality.

[0011] In some embodiments, the acting assembly includes a rotating portion, a passive portion and an acting protrusion extending from the rotating portion, wherein the passive portion is connected to the transmission member and is configured to interact with the detection member.

[0012] In some embodiments, the active protrusion is arranged to extend along a straight line.

[0013] In some embodiments, the two surfaces with different heights are arranged on a side of the active protrusion facing the detected component.

[0014] In some embodiments, the rotation angle of the active protrusion is 20°-70°.

[0015] In some embodiments, the action protrusion is further provided with a groove or an avoidance portion, and the groove or the avoidance portion is recessed in a direction opposite to the rotation direction of the action component.

[0016] In some embodiments, the acting component rotates along an axis parallel to the first direction, or rotates along an axis parallel to the second direction, or rotates along an axis parallel to the third direction.

[0017] In some embodiments, the housing is further formed with a guide groove for mounting the transmission member, and the developing box further includes a covering member, which covers the guide groove from above the housing.

[0018] In some embodiments, the acting component is connected to the transmission member via a gear and rack.

[0120] It should be understood that the various embodiments described below are not isolated from each other, and those skilled in the art may combine the structures of the following embodiments with each other according to design requirements.

[0121] Example 1

[0122]

Overall structure of the developer cartridge

[0123] The developing box 1 includes a shell 2 forming a developer chamber 10 and a rotating member 3 rotatably mounted in the shell 2. The rotating member 3 can be, for example, a developing member 31 for conveying the developer outward, or a powder feeding member 32 arranged adjacent to the developing member 31 and conveying 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 clumping on the one hand and convey the developer toward the powder feeding member 32 on the other hand. The developing box also includes a handle 23 connected to the shell 2, and the developing member 31 and the handle 23 are respectively located at both ends of the shell 2 along the installation direction.

[0124] The developing member 31 rotates about a first axis L1, and the housing 2 extends along 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 and second directions. 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 upward of the developing cartridge, and the other end 56 of the third direction points downward of the developing cartridge.

[0125] Hereinafter, the left end of the developer cartridge is referred to as the driving end, and the right end is referred to as the conductive end. The detected member 9 in the device is disposed to the right of the developer cartridge, and thus the right end of the developer cartridge may also be referred to as the detecting end. The developer cartridge 1 further includes a detecting device 6 having a portion located at the driving end, another portion located at the detecting end, and a portion located between the driving end and the detecting end. The driving force transmission assembly 4 is configured to transmit the driving force received by the driving force receiving member 41 disposed at the driving end to the rotating member 3 and the detecting device 6.

[0126] The housing 2 has a left surface 21 facing left, a right surface 22 facing right, and a left end cover 27 and a right end cover 28 respectively combined with the housing 2, wherein 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 portion of the driving force receiving member 41 is exposed outward from the left end cover, and a portion of the detection device 6 is exposed outward from the right end cover 28. Figure 1B As shown, the right end cover 28 has an exposure opening 281, the size of the exposure opening 281 is larger than the size of the component of the detection device 6 located at the detection end (the following action component 63); further, the developing cartridge 1 further includes a developer regulating member 29 fixedly mounted on the housing 2, a conductive member 26 combined with the housing 2, and a chip assembly 11 mounted 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 assembly having a substrate 71, an electrical contact 72 (such as Figure 60 As shown) and a chip of a storage unit, it can also be a chip having a substrate, electrical contacts, a storage unit and a movable part that can be movably connected to the electrical contacts. The conductive part 26 is located at the detection end and is used to receive power from the device and supply it to the developing part 31.

[0127] When the developing box 1 is working, the developing member 31 needs to be opposite to the photosensitive member outside the developing box so that the developer on the surface of the developing member 31 can reach the surface of the photosensitive member to realize development. For this purpose, it is more advantageous for the developing box 1 to be pushed toward the photosensitive member. Figure 1C and Figure 2As shown, the developing box 1 also includes a first forced pushing portion 2b1 and a second forced pushing portion 2b2 arranged at the rear of the developing box, wherein the first forced pushing portion 2b1 is located on the left side of the shell body 2, and the second forced pushing portion 2b2 is located on the right side of the shell body 2. Specifically, the first forced pushing portion 2b1 is formed to protrude to the left from the left direction of the shell body 2, and the second forced pushing portion 2b2 protrudes to the left from the right end cover 28. That is to say, along the first direction, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 both protrude in the same direction. Therefore, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 can also both protrude to the right. This structure is conducive to the miniaturization of the developing box 1.

[0128] Generally, the photosensitive member is arranged in the drum frame, the developing box 1 can be first installed on the drum frame in a detachable manner, and then the combination of the developing box 1 and the drum frame is installed on the device in a detachable manner, or the photosensitive member is pre-arranged in the device, and the developing box 1 is directly installed on the device in a detachable manner. The above-mentioned first direction, second direction and third direction are all defined based on the posture of the developing box 1 after being installed on the drum frame or the device.

[0129] [Right end cap]

[0130] In the second direction, the right end cap 28 is located behind the conductive member 26. A portion 282 of the right end cap 28 forms a second forced-pushing portion 2b2, and a portion of the active component is exposed through the exposed opening 281. When viewed in the first direction, the right end cap 28 does not overlap with the powder filling port 2a3 located at the detection end. When the developer in the developer cartridge is depleted, the user can refill the developer cartridge without removing the right end cap 28. In the third direction, the powder filling port 2a3 is located below the active component 63. With the protruding active component, when the user refills the developer cartridge, there is no interference with the active component 63. The active component 63 and the powder filling port 2a3 are both visible to the user, significantly reducing the risk of damage to the active component 63. In the first direction, the powder filling port 2a3 is located between the second forced-pushing portion 2b2 / 282 and the conductive member 26.

[0131] [Paper Guide]

[0132] When the developing box 1 is working, the imaging medium (such as printing paper) will pass through the developing box along the second direction from the bottom of the developing box 1 along the third direction. In order to keep the moving path of the imaging medium stable, the developing box 1 further includes a paper guide 2d provided under the shell 2. Figure 1C As shown, the paper guide 2d has a continuous surface extending basically along the first direction and the second direction. Preferably, the surface of the paper guide 2d is a smooth surface. More preferably, along the first direction, the surface of the paper guide 2d is a plane, and along the second direction, the surface of the paper guide 2d is a plurality of adjacent planes, and every two adjacent planes intersect at a line parallel to the first direction.

[0133] In practice, in order to prevent the leakage of developer, Figure 1B As shown, along the first direction, the developing box 1 further includes a first sealing member 39 located at both longitudinal ends of the developing member 31, and Figure 3 As shown, along the second direction, the developing box also includes a second seal 38 and a third seal 37, at least a portion of which is located in front of the developing member 13, the first seal 39 is preferably felt / sponge, which is used to seal at the longitudinal end of the developing member 31, the second seal 38 is preferably a sheet seal, which is used to contact and seal with the circumferential surface of the developing member 31, and the third seal 37 is preferably a sponge, which is used to contact and seal with the circumferential surface of the developing member 31.

[0134] Currently, the first seal 39, the second seal 38 and the third seal 37 are all combined with the housing 2 by sticking double-sided tape on one side. On the one hand, this method is not conducive to automated production, and the first seal 37 located at the two longitudinal ends of the developer will be subjected to a large pulling force, causing the first seal to be torn apart; on the other hand, this method has low installation accuracy, resulting in poor sealing effect. The utility model adopts the method of injecting adhesive on the side of the first seal 39 / second seal 38 facing the housing to achieve precise combination of the first seal 39 / second seal 38 and the housing 2. Figure 1C As shown, two injection ports 2e are further provided below the housing 2. Each injection port 2e is in communication with at least one of the first seal 39 and the second seal 38. Thus, 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. Injecting the adhesive through the injection port 2e not only increases the bonding strength between the seals and the housing 2, but also effectively fills the gaps between the first seal 39, the second seal 38, and the third seal 37, as well as the gaps between each of the seals and the housing 2. Furthermore, injecting the adhesive through the injection port 2e allows for automated production of the developer cartridge 1. Preferably, along the first direction, the paper guide 2e is located between the two injection ports 2e to prevent the paper guide 2d from blocking the injection port 2e. Furthermore, along the first direction, the paper guide 2e 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.

[0135]

Drive force transmission component

[0136] The driving force transmission assembly 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 assembly 4 further includes an idler wheel 45 located between the driving force receiving member 41 and the detection 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 the stirring member driving member 44 transmits the driving force to the detection device 6. In some embodiments, the driving force delivered to the detection device 6 can also come directly 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 configured to rotate around an axis parallel to the first direction, or can be configured to reciprocate in a direction substantially parallel to the second direction. The driving force transmission method between the various driving members can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving member is configured as a gear.

[0137] The driving force receiving member 41 rotates around a second axis L2 parallel to the first direction, and the detected member 9 is configured as a rod that can rotate around a third axis L3 parallel to the first direction, including a rotating part 93 and a first rod 91 and a second rod 92 connected to the rotating part 93, wherein the second rod 92 is used to interact with the detection device 6, and the first rod 91 is used to be detected by the equipment.

[0138]

Detection device

[0139] The detection device 6 includes a driving component 61 arranged at the driving end, an acting component 63 arranged at the detection 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 that is not perpendicular to the first direction, thereby forcing the acting component 63 to interact with the detected member 9. Preferably, the movement 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 box no longer needs to be provided with components such as gears and ratchets for transmitting driving force, or the number of components such as gears and ratchets for transmitting driving force is reduced. The structure of the detection end is simplified, and when the developing box is assembled, it is only necessary to focus on the assembly of the driving end.

[0140] [Drive components]

[0141] 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 portion 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 portion of the counting member 613 is closer to the housing 2 than the stirring member driving member 44. Figure 4B As shown, along the first direction, at least the portion of the counting member 613 used to interact with the transmission member 62 (such as the protrusion described below) is closer to the shell 2 / left surface 21 / right surface 22 than the driving member 612 and / or the stirring member driving member 44. Preferably, the counting member 613 as a whole is closer to the shell 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 portion of the counting member 613 is closer to the shell 2 / left surface 21 / right surface 22 than the idler wheel 45 / driving force receiving member 41. In this way, the size of the developing box 1 in the first direction can be reduced, which is conducive to the miniaturization of the developing box 1.

[0142] [Drive force cutoff of drive unit]

[0143] The counting member 613 and the driving member 612 may be formed integrally or separately. After the detection is completed, the counting member 613 is prevented from moving and remains stationary by a separation mechanism provided in the developing cartridge 1. Specifically, when the counting member 613 and the driving member 612 are formed integrally, after the detection is completed, the counting member 613 as a whole will no longer receive the driving force. For example, the counting member 613 may be forced to move in a first direction as a whole, or the counting member 613 may be moved in a translational manner as a whole, so that the counting member 613 is separated 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 wheel 45). Disengagement; in the case where the counting member 613 and the driving member 612 are formed as separate bodies, after the detection is completed, the counting member 613 and the driving member 612 may be disengaged, but the driving member 612 may not be disengaged from the driving source, or the counting member 613 and the driving member 612 may be disengaged from the driving source as a whole; in some embodiments, regardless of whether the counting member 613 and the driving member 612 are formed as one piece, the driving member 612 may also be configured as a gear with a toothless portion. During the detection process, the gear portion of the driving member 612 is opposite to the driving source and receives the driving force. When the detection is completed, the toothless portion of the driving member 612 is opposite to the driving source and does not receive the driving force. The toothless portion is a separation mechanism.

[0144] The counting member 613 includes a chassis 613a, a coupling portion 613b, a driving force receiving portion 613c and a plurality of protrusions arranged on the chassis 613a. The counting member 613 and the driving member 612 are coupled to each other through the coupling portion 613b. The driving force of the driving member 612 is transmitted to the counting member 613 through the coupling of the driving force output portion 6122 arranged on the driving member 612 and the driving force receiving portion 613c arranged on the counting member 613.

[0145] When observed along the rotation axis L4, the counting piece 613 is circular, and its radius R can vary between 5.0mm-7.0mm, and the optimal range is 5.5mm-6.5mm. Especially in the structure where multiple gears are provided at the driving end, if the diameter of the counting piece 613 is too large, it will be detrimental to the layout of other gears and cause the miniaturization of the developing box 1 to fail; on the contrary, if the diameter of the counting piece 613 is too small, the rotation speed of the counting piece 613 will be accelerated, thereby causing increased wear between the various components of the driving force transmission assembly 4, and even causing the detection device 6 to fail in detection.

[0146] When the driving force receiving member 41 and the driving member 612 are both configured as gears, the gear ratio between the two is in the range of 0.7-1.3, preferably 0.8-1.1. In the scheme where the transmission member 62 adopts translation, this gear ratio is conducive to the miniaturization of the powder box end and improves the transmission accuracy.

[0147] Method 1

[0148] When the counting member 613 and the driving member 612 are separated, the separation mechanism includes an elastic pushing member 611, a guide protrusion 613h provided on the counting member 613, and a groove 615 that cooperates with the guide protrusion 613h. The counting member 613 rotates around the column 614 provided on the housing 2, and the groove 615 is provided in the circumferential direction of the column 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 guide protrusion 613h does not abut against the groove 615. Yes, the elastic pushing member 611 is in an elastically deformed state. When the detection is completed, the guide protrusion 613h is opposite to the groove 615. Under the action of the elastic pushing member 611, the counting member 613 is forced to be pushed to a position separated from the driving member 612 along the first direction. At this time, the counting member 613 is forced to be pushed to a position closer to the shell 2, and the position of the driving member 613 relative to the shell 2 does not change. Therefore, even if the driving member 613 is set to a full-tooth gear, the counting member 613 will not be driven by the driving member 613 that continues to rotate.

[0149] Method 2

[0150] 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 elastic deformation state. When the detection is completed, the elastic pushing member 611 releases the elastic force so that the guide protrusion 613h is opposite to the groove 615, and the counting member 613 and the driving member 612 are pushed as a whole along the first direction to a position closer to the shell 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.

[0151] In this embodiment and method one, 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. In this case, one end of the tension spring is connected to the shell 2, and the other end is connected to the counting member 613 or the driving member 612.

[0152] Method 3

[0153] As described above, the separation mechanism can also be a toothless gear arranged on the driving member 612. In other embodiments, the separation 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 separate / disengage from each other, or the counting member 613 and the driving member 612 are disengaged from the driving source as a whole.

[0154] Specifically, a first magnet is installed on the shell 2 and a second magnet is installed on the counting member 613, and a repulsive force is generated between the pair of magnets. During the detection process, the pair of magnets are relative, and the counting member 613 can be combined with the driving member 612, or the counting member 613 and the driving member 612 are kept combined with the driving source as a whole. 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 / disengaged from each other, or the counting member 613 and the driving member 612 are disengaged from the driving source as a whole.

[0155] Alternatively, the first magnet may be mounted on the left end cap 27, while the second magnet may still be mounted on the counter 613. An attractive force may be generated between the pair of magnets, which is greater than the elastic force of the elastic pushing member 611. During the detection process, the counter 613 can be driven by the driving member 612. Upon completion of the detection, the pair of magnets are no longer facing each other, and the attractive force between them disappears or decreases. Under the action of the elastic pushing member 611, the counter 613 and the driving member 612 separate / disengage from each other. Similarly, when the second magnet is mounted on the driving member 612, upon completion of the detection, the counter 613 and the driving member 612 are disengaged from the driving source as a whole.

[0156] When the detection device 6 is provided with an elastic return member 64, one end of the elastic return member 64 abuts against the transmission member 62, and the other end abuts against the shell 2. It can also be arranged between the action component 63 and the shell 2. The elastic return member 64 can be a compression spring or a tension spring; in the above implementation method, the elastic force exerted by the elastic pushing member 611 is greater than the elastic force of the elastic return member 64. When the elastic pushing member 611 pushes the counting member 613 and / or the driving member 612, the movement speed of the transmission member 62 will be accelerated, and eventually, the rotation speed of the detected member 9 will also be accelerated, thereby forming a phenomenon that the detected member 9 is accelerated.

[0157] Method 4

[0158] In this embodiment, the separation mechanism no longer has an elastic pushing member. Figure 5B As shown, the left end cover 27 is provided with a guide path 271 and a forced pushing surface 272 located in the groove-shaped guide path, and the forced pushing surface 272 is provided as an inclined surface, as shown in FIG. 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 pushing 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 pushing member 272 accelerates the rotation speed of the counting member 613. Accordingly, 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.

[0159] Method 5

[0160] In the above-mentioned method three, the acceleration process of the transmission member 62 / the 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 / the detected member 9 can also be achieved solely by the elastic reset member 64 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 64 releases the elastic force and forces the transmission member 62 / the counting member 613 to be accelerated.

[0161] [Structure of counting pieces]

[0162] 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 the first flat portion 613g1 is provided between the positioning protrusion 613d and the first toggle protrusion 613e, and the second flat portion 613g2 is provided between the first toggle protrusion 613e and the second toggle protrusion 613f. The number of the toggle protrusions can also be increased or decreased according to the detection requirements of the detection device. The following description will take the counting piece 613 provided with the first toggle protrusion 613e and the second toggle protrusion 613f as an example.

[0163] 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 the multiple protrusions include positioning protrusions 613d arranged at intervals along the circumferential direction of the chassis 613a.

[0164] 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 holding surface 613e2 / 613f2 is parallel to the flat portion 613g. The larger the size of the holding surface 613e2 / 613f2, the closer the transmission member 62 is held. 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 the two pushes of the transmission member 62. It can be seen that the detection requirements of the equipment are different. 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 all be different. Designers can make adjustments according to detection requirements.

[0165] like Figure 6BAs shown, in some embodiments, the length of the first flat portion 613g1 and the second flat portion 613g2 can vary between 1 mm and 10 mm, preferably, the length of the first flat portion 613g1 and the second flat portion 613g2 is 3 mm to 4 mm; the height of the retaining surface 613e2 / 613f2, that is, the value of the descending surface 613e3 / 613f3, can vary between 1 mm and 10 mm, preferably between 3 mm and 6.5 mm, the height of the retaining surface 613e2 of the first toggle protrusion is more preferably between 4.5 mm and 6 mm, and the height of the retaining surface 613e2 of the second toggle protrusion is more preferably between 4.5 mm and 6 mm. The height of the holding surface 613f2 is more preferably 4.5mm-6.5mm; the angle a1 between the rising surface 613e1 of the first shifting protrusion and the flat portion 613g can vary between 5°-85°, preferably between 25°-65°, more preferably, the angle a1 varies between 30°-35°, and the angle a2 between the rising surface 613f1 of the second shifting protrusion and the flat portion 613g can vary between 10°-90°, preferably, the angle a2 varies between 35°-75°, more preferably, the angle a2 varies between 60°-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 in which the toggle protrusion is used to push the transmission member to move in the first direction, by detailed research on the height, inclination angle and distance between adjacent toggle protrusions, it can be ensured that the toggle protrusion and the transmission member cooperate more smoothly, the transmission is more stable and the detection effect is better.

[0166] like Figure 6C As shown, in other embodiments, the counting piece 613 is provided with three toggle protrusions, wherein two of the toggle protrusions have the same structure, for example, the structure of the two toggle protrusions is the same as the structure of the above-mentioned first toggle protrusion 613e, and in this embodiment, they are respectively referred to as the first toggle protrusion and the second toggle protrusion, and the structure of the other toggle protrusion is different from the first toggle protrusion 613e, for example, it has the same structure as the above-mentioned second toggle protrusion 613f, and in this embodiment, it is referred to as the third toggle protrusion. At this time, the counting piece 613 will form three flat portions, namely, a first flat portion 613g1 located between the positioning protrusion 613d and the first toggle protrusion, a second flat portion 613g2 located between the first toggle protrusion and the second toggle protrusion, and a third flat portion 613g3 located between the second toggle protrusion and the third toggle protrusion. Specifically, in the rotation direction of the counting member, the first and second toggle protrusions are located downstream of the third toggle protrusion, that is, during the detection process, the transmission member 62 sequentially contacts the first, second and third toggle protrusions.

[0167] During the detection process of the detection device 6, the effective detection angle a5 of the counting member 613 ranges from 200° to 320°, preferably from 250° to 280°. By limiting a5 to the above range, it can be ensured that within the detection cycle of the detection device 6, the transmission member 62 can be moved at least twice by the counting member 613. Depending on the model of the developing box 1, the number of times the number of moves is at least three times or more. The detection accuracy of the detection device 6 can be precisely controlled, and it is also conducive to the miniaturization of the counting member 613.

[0168] Based on the above structure and movement process of the counting member 613, the transmission ratio between the driving force receiving member 41 and the counting member 613 varies between 0.05-0.5, preferably between 0.1-0.2. Setting the transmission ratio within the above range has the following beneficial effects:

[0169] This setting is conducive to the transmission member 62 receiving a stable driving force from the receiving counting member 613, and will not cause problems such as accelerated wear between components due to excessive rotation speed, excessive stress concentration, or even the transmission member 613 being broken; at the same time, this setting will not cause the counting member 613 to rotate too slowly, so that the detection device 6 cannot interact with the detected member 9 in time, which not only wastes electricity and leads to low detection efficiency, but also is very likely to cause the detection failure of the detection device 6.

[0170] [Structure and installation of transmission parts]

[0171] The transmission member 62 includes a forced pushing portion 621 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 633. Furthermore, the transmission member 62 also includes a reset member 64. When the transmission member 62 is pushed to the right / detection end, the reset member 64 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 64 may not be a separate component. At this time, the reset of the transmission member 62 is driven by the reset of the detected member 9 to drive the acting component 63, and then the acting component 63 forces the transmission member 62 to reset.

[0172] like Figure 3 As shown, along the third direction, the housing 2 includes an upper housing 2a located above and a lower housing 2b located below, and the developer chamber 10 is located between the upper housing 2a and the lower housing 2b. 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. In this way, the transmission member 62 will not interact with the developer during movement, and leakage of the developer is also avoided.

[0173] The developer cartridge 1 further includes a cover 24 that prevents the transmission member 62 from falling out. The cover 24 covers the guide slot 25 from above. This prevents the transmission member 62 from falling out of the guide slot 25, protecting it from external contact. Furthermore, it enhances the aesthetics of the developer cartridge. The cover 24 can be coupled to the housing 2 by snapping, welding, bonding, magnetic attraction, or other methods.

[0174] The following describes the installation structure of the transmission member 62 and the changes in the movement mode.

[0175] Change 1

[0176] like Figure 7 As shown, the transmission member 62 is plate-shaped as a whole, and the covering member 24 is at least a pair of intermittent protrusions arranged on the upper shell 2a, and the pair of intermittent protrusions 24 are arranged relatively along the second direction. The relative arrangement includes a pair of intermittent protrusions 24 that are directly opposite to each other and staggered relative to each other in the second direction, and the guide groove 25 is located between the pair of spaced protrusions 24; further, each intermittent protrusion 24 also extends a limiting portion along the second direction toward the guide groove 25 to prevent the transmission member 62 from falling off.

[0177] Change 2

[0178] like Figure 8A As shown, the transmission member 62 is configured to rotate around 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 one pair of guide plates 252 protrude upward from the shell 2a, and the guide groove 24 is located between the pair of guide plates 25. Similarly, in the second direction, the pair of guide plates 252 can be directly opposite to each other or arranged in a staggered manner. The rotating shaft 625 is provided on the moving part 622, and the covering member 24 covers the rotating shaft 625 to prevent the transmission member 62 from falling off.

[0179] When the forced pushing portion 621 receives the forced pushing force, the transmission member 62 as a whole swings around the rotation axis L6. During the swinging process, the transmission portion 623 directly or indirectly interacts with the detected member 9; Figure 8B As shown, along the first direction, the end point of the transmission member 62 at the detection end is P, and the dotted line in the figure shows the position of the transmission member 62 after the swing. Before the swing, the transmission member 62 is in the first position, and after the swing, the transmission member 62 is in the second position. Taking the surface 2a2 of the shell 2 / upper shell 2a at the detection end as the reference, it can be seen that when the transmission member 62 is in the first position, the end point P has a distance h1 to the surface 2a, and when the transmission member 62 is in the second position, the end point P has a distance h2 to the surface 2a, and the h1 is not equal to h2, that is, during the detection process of the detection device 6, the transmission member 62 still has a movement distance along the first direction.

[0180] Furthermore, in order to reduce the friction during the movement of the transmission member 62, the developer box also includes a plurality of ribs 251 arranged in the guide 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 guide groove 25 is reduced, and the friction between the two is also reduced. It is feasible that the ribs 251 can also be set on the transmission member 62. Applying lubricating powder on the guide groove 25 or the transmission member 62 or replacing it with a material with a lower friction coefficient (such as POM material) can also reduce the friction between the two and improve the transmission efficiency and detection accuracy.

[0181] [Structure of the active component]

[0182] The action component 63 is configured to rotate around the axis L5. During the rotation, the action component 63 interacts with the detected part 9. The axis of rotation of the action component 63 can be parallel to any one of the first direction, the second direction and the third direction. In the following, the axis L5 perpendicular to the first direction is taken as an example.

[0183] The action assembly 63 includes a rotating portion 631 and an action protrusion 632 and a passive portion 633 extending from the rotating portion 631. The action protrusion 632 is arranged in a non-linear extension manner along a direction perpendicular to the rotation axis L5. It can extend directly from the rotating portion 631 or from a connecting portion 636 connected to the rotating portion 631. Figure 10A As shown, the action protrusion 632 is claw-shaped as a whole, and the groove / avoidance portion 6323 is provided in the action protrusion 632 and is recessed in the direction opposite to the rotation direction r3 of the action component 63. Figure 10B and Figure 10C As shown, when the action protrusion 632 rotates with the rotating portion 631, the action portion 6324 of the action protrusion 632 will directly contact the surface 921 of the second rod 92 facing the action protrusion 632 (as shown in FIG. Figure 12B As shown), the active protrusion 62 will not contact the edge 922 first and then contact the surface 921, and the edge 922 is the boundary line of the surface 921 close to the housing 2 / transmission member 62 / active component 63 side.

[0184] In the developing box in which the driving assembly 4 is entirely located at the driving end, when the developing box is working, the driving end is subjected to a larger torque, which may cause the developing box as a whole to appear higher at the right / detection end than the left / driving end. In the detection process, the action protrusion may contact different positions of the detected member 9, thereby causing a detection error. For this reason, the action portion 6324 of the action protrusion 632 in this embodiment, which is used to abut against the second rod 92, needs to be arranged closer to the free end 923 of the second rod 92. It can be seen that during the operation of the action assembly 63, along the third direction, when the contact position of the action portion 6324 and the second rod 92 is higher than the predetermined position, the contact position of the action portion 6324 and the second rod 92 can be returned to the predetermined position by cutting off a part of the action protrusion 632. Figure 10A and Figure 10B As shown, two surfaces 6321 / 6322 of different heights are formed above the action protrusion 632, with a height difference between the two surfaces. In this way, the position where the action protrusion 632 contacts the second rod 92 can be moved downward. In this way, when the action protrusion 632 is configured to contact different positions of the detected member 9, the rotation speed of the detected member 9 can be made different, and the detection function can also be achieved.

[0185] like Figure 10D As shown, along the radial direction of the rotating portion 631, the action protrusion 632 has a farthest point M. With the farthest point M as a reference, the angle that the action protrusion 632 can rotate in this embodiment is a4. The line of sight in the figure indicates that the action protrusion 632 is located at a position not touching the second rod 92, and the dotted line indicates the position of the action protrusion 632 when the second rod 92 is moved to a predetermined position. The angle a4 can vary in the range of 20°-70°, preferably 30°-45°.

[0186] Figure 11A and Figure 11B Another structure of the action protrusion 632 is shown. Different from the above embodiment, the action protrusion 632 in this embodiment is provided with an inclined surface 632a and a plane 632b on the side facing the second rod 92, and the groove / avoidance portion 6323 extends within the plane 632b and the inclined surface 632a along the third direction. When the action protrusion 632 contacts the second rod 92, the edge 922 will not contact the action protrusion 632, and the action portion 6324 directly contacts the surface 921.

[0187] In one embodiment, the passive portion 633 cooperates with the shaft hole of the transmission member 62. When the transmission member 62 reciprocates along the first direction, the passive portion 633 and the transmission member 62 can move relative to each other. That is, the size of the hole is larger than the size of the shaft. Figure 7 As shown, the passive portion 633 is configured as a shaft, and a hole 6231 is provided on the transmission member 62 .

[0188] like Figure 9B As shown, the hole 6231 is configured as a square hole, and the passive part 633 is a cylinder. Specifically, the diameter of the cylinder 633 varies between 1mm and 8mm, preferably between 2.5mm and 3.5mm. Along the first direction, the size of the hole 6231 varies between 2mm and 8mm, preferably between 3mm and 3.5mm. Along the second direction, the size of the hole 6231 varies between 2mm and 10mm, preferably between 4mm and 5mm. It is feasible 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, so as to avoid the existence of a virtual position. Along the second direction, the size of the hole 6231 is larger than the diameter of the cylinder 633, thereby reserving space for the movement of the cylinder 633. If the size of the shaft is too small, not only will it be insufficiently strong but also easy to break. If it is too large, it will occupy a large space, which is not conducive to the miniaturization of the developer box.

[0189] The following combination Figure 13 、 Figure 14A 、 Figure 14B and Figure 15 、 Figure 16A 、 Figure 16B A modified embodiment of the action assembly 63 will be described.

[0190] Transformation 1

[0191] like Figure 13 As shown, the action assembly 63 includes a toggle member 634 that can rotate around the rotation axis L5 and a movable member 64 for driving the toggle member 634. The movable member 64 includes a base 641 and a movable portion 642 that can move relative to the base 641. The movable member 642 is configured to rotate in only one direction. The toggle member 634 includes a central axis 6340 and a first toggle rod 6341, a second toggle rod 6342, and a ratchet 6343 combined with the central axis. The ratchet 6343 is configured to be pushed by the movable portion 642. Preferably, the ratchet 6343 is disposed in the center. At one end of the central shaft 6340, the first lever 6341 and the second lever 6342 extend radially outward from the surface of the central shaft 6340 respectively. Along the rotation axis L5, the first lever 6341 and the second lever 6342 are distributed at different axial positions, that is, the first lever 6341 and the second lever 6342 are at different distances from any end of the central shaft 6340, or in other words, the first lever 6341 and the second lever 6342 have a height difference, so that the positions of the detected part 9 moved by the first lever 6341 and the second lever 6342 are different.

[0192] During the detection process, the transmission part 623 moves to the right / detection end and pushes the movable member 64. Then, the movable part 642 pushes the ratchet 6343 to rotate, and 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 member 64, the movable member 64 is pushed by a component such as an elastic member and resets. Figure 14A As shown, the first lever 6341 contacts the surface 921 of the second rod at point Q1. As the ratchet 6343 is turned, the detected member 9 is pushed to rotate around the rotating portion 93 in the direction shown by r until the first lever 6341 is disengaged from the second rod 92. As the ratchet 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 away from the free end 923 of the second rod 92. That is, point Q2 is closer to the rotating portion 93 than point Q1. When the rotation speed of the ratchet 6343 remains unchanged, the detected member 9 will rotate faster under the push of the second lever 9342, thereby causing the detected member 9 to be accelerated.

[0193] Regarding the movable member 64, after the movable portion 642 pushes the ratchet 6343, while the elastic member forces the movable member 64 to return to its original position, the movable portion 642 is supported by the ratchet 6343 and rotates, so that the movable portion 643 can enter a position for the next push of the ratchet 6343. In some embodiments, the movable member 64 is connected to the transmission portion 623 and can move as the transmission portion 623 moves.

[0194] Transformation 2

[0195] In this modified embodiment, the action component 63 is configured as a rotating member that can rotate around an axis that is not perpendicular to the first direction, including a central axis 635, a guide path 6351 arranged on the central axis 635, a guide slope 6352 located on the guide path, and a shift rod 6353 connected to the central axis 635. The transmission member 62 is still configured to be able to reciprocate along a direction that is not perpendicular to the first direction, and the transmission part 623 of the transmission member 62 is configured to be guided by the guide path 6351. Preferably, the guide path 6351 is a groove arranged on the central axis 635, and the guide slope 6352 is arranged in the groove 6351.

[0196] like 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 inclined surface 6352, and the rotating member 63 is forced to rotate around its axis in the direction indicated by r1. At the same time, the shift rod 6353 shifts 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 inclined surface 6352. Under the action of an elastic member, the rotating member 63 is reset, and the shift rod 6353 no longer shifts the second rod 92.

[0197] Transformation Three

[0198] 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 can 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 toward 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.

[0199] The arcuate 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 portion 622 / forced pushing portion 621 than the second end 6232b. In this way, when the transmission member 62 moves toward the right / detection end, the transmission portion 623 / arcuate 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 portion 623 / arcuate surface / inclined surface 6232 is still in contact with the second rod 92, so that the second rod 92 can be smoothly reset.

[0200] Transformation 4

[0201] In this modified embodiment, the action component 63 and the transmission member 62 are connected in a gear and rack manner, such as Figure 20A 、 Figure 20B 、 Figure 21A and Figure 21B As shown, the transmission part 623 is configured as a rack, and the action assembly 63 includes a rotating part 631, an action protrusion 632 connected to the rotating part 631, and a passive part 633. The passive part 633 is configured as a gear. 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, which in turn causes the rotating part 631 to drive the action protrusion 632 to swing. During the swinging process of the action protrusion 632, the second rod 92 is toggled.

[0202] [Reset of the counter]

[0203] like Figure 5B 、 Figure 5C As shown, the left end cover 27 is provided with a first indicating portion 273, the driving member 612 is provided with a second indicating portion 6121, and the counting member 613 is provided with a third indicating portion 613d1. Before the detection device 6 starts detection, or after the detection device 6 is reset, the first indicating portion 273, the second indicating portion 6121 and the third indicating portion 613d1 are always roughly aligned along the first direction. 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, teeth, arrows, etc., as long as they can serve as an indication.

[0204] To facilitate the resetting of the counting member 613, the positioning protrusion 613d of the counting member 613 is also provided with a force-applying portion 613j. 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. At least a portion of the force-applying portion is exposed to the outside. When the detection device needs to be reset, the rotating action component 63 causes the transmission member 62 to rotate around the axis. At the same time, the force is applied to the force-applying portion 613j, so that the first indication portion 273, the second indication portion 6121 and the third indication portion 613d1 are aligned along the first direction.

[0205] Furthermore, to prevent unnecessary movement of the transmission member 62, the positioning protrusion 613d is further provided with a limiting portion. Preferably, the limiting portion overlaps with the third indicating portion 613d1 to simplify the structure of the counting member 613. More preferably, the limiting portion is a limiting groove.

[0206] Furthermore, Figure 5A and Figure 22 As shown, at the driving end, the end face (left end face) of the upper shell 2a is not a whole plane. Along the first direction, the left end face of the upper shell 2a includes a first left end face 2L1 and a second left end face 2L2, wherein the second left end face 2L2 is closer to the detection end than the first left end face 2L1, and 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, and at least a portion of the counting member 613 is exposed outward through the 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 space for the counting member 613 to move when it moves toward the direction close to the shell 2, so that the counting member 613 does not need to be set further to the left, which can achieve the effect of reducing the size of the developing box in the first direction.

[0207] Preferably, the exposed portion 2c is exposed upward, which is more convenient for the user to observe; 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 have an additional opening for resetting the counting member 613. The user can reset the detection device 6 by applying a force to the force-applying portion 613i through the exposed portion 2c; further, the protrusion 613d / 613f of the counting member 613 is arranged to face toward or away from the shell 2, that is, the counting member 613 is located between the left end cover 27 and the shell 2, so that the protrusion 613d / 613f can be effectively protected by the left end cover 27, the driving member 612 and the shell 2.

[0208] [Delayed movement of counting piece]

[0209] In some embodiments, the detected member 9 is configured to require the driving force receiving member 41 to be driven for a period of time before it begins to be moved. 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.

[0210] It is achievable that, along the rotation 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 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.

[0211] like Figure 23 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. 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. The first gear 441 is a full-tooth gear for receiving the driving force from the driving force receiving member 41. 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.

[0212] 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 has no 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 toggle portion 4411 is provided in the intermediate portion 443. Corresponding to the toggle portion 4411, a toggle portion 612c is provided on the driving member 612. When the developing box is assembled, along the first direction, the toggle portion 4411 and the toggle portion 612c are both located between the first gear 441 and the second gear 442, the toggle portion 612c is located on the rotation path of the toggle 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.

[0213] 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 and the toggle portion 612c are disengaged, 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 length of the driving member 612 / counting member 613 is the length of time required for the toggle portion 4411 to start contacting 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 device's delay requirements for the detected member 9, so that the moment when the toggle portion 4411 and the toggle portion 612c begin to contact changes.

[0214] Preferably, the toggle portion 4411 is integrally formed 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 closer to the second gear 442 than the teeth of the first gear 441 .

[0215] [Acceleration of the test piece]

[0216] 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 developer cartridge 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.

[0217] Method 1

[0218] The following combination Figure 24 、 Figure 25A and Figure 25BAnother method of accelerating the counter 613 will be described.

[0219] In this embodiment, still taking the counting member 613 and the driving member 612 as an integrally formed example, the driving member 612 is configured as a toothless gear. Furthermore, the driving member 612 also includes an arc surface 6124 coaxially arranged with the toothless gear and a straight surface 6125 adjacent to the arc surface. The elastic pushing member 611 is configured as a torsion spring, one end of the torsion spring abuts against the driving member 612, and the other end abuts against a component outside the driving member 612.

[0220] like Figure 25A As shown, before the detection device 6 reaches the final detection stage, the torsion spring 611 contacts the arcuate surface 6124 and does not hinder the rotation of the driving member 612. When the detection device 6 reaches the final detection stage, the torsion spring 611 disengages from the arcuate surface 6124 and begins to contact the straight surface 6125. During the process of the torsion spring 611 switching the contact surface, the torsion spring 611 releases the torque, thereby forcing the driving member 612 to rotate faster. Furthermore, the driving member 612 is provided with an opening 6123 to facilitate the user to reset the torsion spring 611 from the outside.

[0221] Method 2

[0222] The acceleration of the driving member 612 can also be achieved by setting the second gear 442 of the stirring member gear 44 as a toothless gear, the diameter of the second gear 442 being smaller than the diameter of the first gear 441. At the same time, the driving member 612 is also set as a double gear. Along the first direction, the driving member 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 detection end 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 the diameter of the first gear 441, when the second gear 442 drives the sub-gear, the driving member 612 will be accelerated.

[0223] Example 2

[0224] On the basis of the first embodiment, this embodiment further optimizes the structure of the detection device 6 to further improve the detection accuracy of the detection device.

[0227] Regarding the acceleration of the detected member 9, based on the above-mentioned fourth method of [cutting off the driving force of the driving component], this embodiment provides the following acceleration method.

[0228] like Figure 26 As shown, the driving member 612 and the counting member 613 are formed separately, and the two rotate around the rotation axis L4. Along the rotation axis L4, the counting member 613 is closer to the shell 2 / detection end than the driving member 612. The elastic pushing member 611 is arranged between the counting member 613 and the left end cover 27, and the guide path 271 is arranged along the rotation direction of the counting member 613. Similarly, the groove 615 is arranged on the guide path 271, and an inclined surface / pushing surface 272 inclined relative to the rotation axis L4 is formed in the groove 615. During the detection process of the detection device 6, the counting member 613 moves along the guide path 271. When the detected member 9 needs to be accelerated, a part of the counting member 613 reaches the inclined surface 272, and the elastic pushing member 611 releases the elastic force, so that the counting member 613 can achieve accelerated rotation while continuing to move along the inclined surface 272. At the same time, the counting member 613 forces the transmission member 62 to accelerate as well. Finally, the accelerated movement of the detected member 9 can be achieved; the acceleration process will be described below.

[0229] As described in [Delayed Movement of Counting Component] in the first embodiment, when the driving component 612 and the counting component 613 are formed separately, a driving force output portion 6122 (such as Figure 32B As shown), a driving force receiving portion 613c is provided in the counting member 613, and the driving force transmission is realized by the combination of the driving force output portion 6122 and the driving force receiving portion 613c. When the counting member 613 needs to be delayed, that is, the rotation time of the counting member 613 needs to be later than the rotation time of the driving member 612, the driving force output portion 6122 can be configured so that, during the period when the driving member 612 is driven and starts to rotate at a predetermined angle, the driving force output portion 6122 and the driving force receiving portion 613c are not combined, and the driving force output portion 6122 and the driving force receiving portion 613c start to combine only after the driving member 612 rotates to the predetermined angle.

[0230] like Figure 27 As shown, the counting member 613 includes a chassis 613a, a coupling portion 613b, a driving force receiving portion 613c and a plurality of protrusions 613d-613f arranged on the chassis 613a, and at least a portion of the coupling portion 613b enters the counting member 613 to realize the combination of the two; preferably, the driving force receiving portion 613c and the plurality of protrusions are respectively arranged on both sides of the chassis 613a, and preferably, the driving force receiving portion 613c is arranged on the side of the chassis 613a facing the driving member 612.

[0231] Furthermore, the counting member 613 is further provided with a guide protrusion 613h which can be guided by the guide path 271, as shown in FIG. Figure 27 As shown, the guide protrusion 613h is arranged on the same side as the multiple protrusions 613d-613f, and along the radial direction of the chassis 613a, the guide protrusion 613h is located radially inside the multiple protrusions, which is beneficial to reducing the size of the counting member 613 in the radial direction; accordingly, the multiple protrusions 613d-613h are located outside the guide path 272 in the radial direction, and this structure can also avoid interference between the guide protrusion 613h and the transmission member 62; further, along the rotation axis L4, the extension dimension of any one of the multiple protrusions 613d-613f is greater than the extension dimension of the guide protrusion 613h, that is, any one of the multiple protrusions 613d-613f is farther away from the chassis 613a or closer to the detection end than the guide protrusion 613h. Through such a design, the size of the counting member 613 in the direction of the rotation axis L4 can also be reduced. Therefore, the overall size of the counting member 613 can be effectively controlled, which is beneficial to the miniaturization of the developing box.

[0232] In some embodiments, in order to prevent the counting member 613 from possibly reversing, for example, during the transportation of the developing cartridge, when the user installs the developing cartridge to the device but has not yet started using it, once the counting member 613 is shaken and reversed, the detection process of the detection device 6 will fail.

[0233] To this end, the detection device 6 involved in this embodiment also includes a first positioning portion 613k. When the developing box is assembled, the first positioning portion 613k abuts against the first abutment portion outside the counting member 613, that is, the reverse rotation of the counting member 613 (rotation in a direction opposite to the predetermined direction) is stopped by the abutment between the first positioning portion 613k and the first abutment portion.

[0234] Preferably, the first abutting portion is an abutting protrusion 275 provided on the left end cover 27. The abutting protrusion 275 is formed as a cantilever provided on the left end cover 27 and has an abutting surface 2751 parallel to the rotation axis L4 and an inclined surface 2752 adjacent to the abutting surface 2751. The abutting surface 2751 abuts against the first positioning portion 613k, thereby preventing the counter 613 from reversing. When the counter 613 rotates in a predetermined direction, the counter 613 is guided by the inclined surface 2752, forcing the abutting portion 275 to elastically deform, thereby allowing the counter 613 to pass. In some embodiments, the first positioning portion 613k is provided at the end of the coupling portion 613b away from the chassis 613a.

[0235] Furthermore, in some embodiments, when the counting member 613 does not need to start working, in order to prevent the counting member 613 from rotating in a predetermined direction, the detection device 6 also includes a second positioning portion 613d2, and the second positioning portion 613d2 abuts against a second abutting portion outside the counting member 613, that is, the forward rotation (rotation in a predetermined direction) of the counting member 613 is stopped by the abutment between the second positioning portion 613d2 and the second abutting portion; preferably, the second positioning portion 613d2 is arranged on one of the multiple protrusions.

[0236] Along the rotation direction r of the counting member 613, the positioning protrusion 613d, the first toggle protrusion 613e and the second toggle protrusion 613f among the multiple protrusions 613d-613f are arranged in sequence, and the second positioning portion 613d2 is set on the positioning protrusion 613d, and the counting member 613 is positioned by abutting with the transmission member 62 (an embodiment of the second abutting portion). Along the rotation direction r4 of the counting member 613, the second positioning portion 613d2 is located at the downstream end of the positioning protrusion 613d.

[0237] The detection process of the detection device 6 in this embodiment will be described below with reference to the accompanying drawings.

[0238] According to the above [Structure and installation of transmission parts] variation 2, such as Figure 28A As shown, the transmission member 62 in this embodiment is also configured to rotate around the rotation axis L6, and the action component 63 for interacting with the detected member 9 is configured to rotate around the rotation axis L5 as mentioned above, and the transmission member 62 and the action component 63 are rotatably connected.

[0239] When the developing box is assembled, the second indicating portion 6121 provided on the driving member 612 is aligned with the first indicating portion 273 provided on the left end cover 27, and the first positioning portion 613k abuts against the first abutting portion 275 located on the left end cover 27. At the same time, the second positioning portion 613d2 abuts against the transmission member 62 (specifically, the forced pushing portion 621 of the transmission member). With the rotation axis L8 as the boundary, the side (left side 62a) where the forced pushing portion 621 of the transmission member 62 is located is pushed toward one end 53 of the second direction (the front of the developing box), and the side (right side 62b) where the transmission portion 623 of the transmission member 62 is located is pushed toward the other end 54 of the second direction (the rear of the developing box), and the reset member 64 undergoes elastic deformation. In this way, both the forward and reverse rotations of the counting member 613 are stopped, and the transmission member 62 is also maintained in a posture with the left side 62a facing forward and the right side 62b facing backward.

[0240] like Figure 28C As shown, the transmission member 62 maintained in the above-mentioned posture will pull the acting component 63 to rotate around the rotation axis L5 by an angle, and the action protrusion 632 will abut against the second rod 92 of the detected member and force the detected member 9 to rotate (the deviated position of the detected member 9). This realizes the function that when the developing box is just installed to the predetermined position of the device, the detected member 9 can be moved once and maintained in the moved position, thereby, the installation of the developing box can be detected by the device.

[0241] like Figure 28B As shown, before the counting member 613 starts working, the positioning protrusion 613d among the plurality of protrusions abuts against the forced pushing portion 621 through the second positioning portion 613d2 provided therein, and the guide protrusion 613h is located downstream of the groove 615 along the rotation direction r4.

[0242] When the driving force receiving member 41 receives the driving force and starts to rotate, the driving member 612 is driven. When the driving force output portion 6122 abuts against the driving force receiving portion 613c as described above, the counting member 613 is driven to rotate around the rotation axis L4 in the direction indicated by r4, as shown in FIG. Figure 29A As shown, after the positioning protrusion 613d is disengaged from the forced pushing portion 621, the reset member 64 releases the elastic force, the transmission member 62 rotates around the rotation axis L6, the left side 62a of the transmission member moves toward the rear of the developing box, and the right side 62b of the transmission member moves toward the front of the developing box, as shown in FIG. Figure 29B As shown, the forced pushing portion 621 enters between the positioning protrusion 613d and the first toggle protrusion 613e. At the same time, the transmission portion 623 drives the action component 63 to rotate around the rotation axis L5, and the action protrusion 632 no longer forces the second rod 92. Figure 29C As shown, the detected member 9 returns to the non-deflected position which is different from the deflected position.

[0243] As the counting member 613 continues to rotate, as Figure 30A and Figure 30B As shown, the first toggle protrusion 613e begins to abut against the forced pusher 621, so that the transmission member 62 returns to the Figure 28A The state shown in FIG. 8 , accordingly, the detected part 9 also returns to Figure 28C The deviated position shown; subsequently, the second toggle protrusion 613f and the positioning protrusion 613d also abut against the forced push portion 621 respectively. It can be understood that each of the multiple protrusions abuts against the forced push portion 621 once, and the action protrusion 632 toggles the second rod 92 once. Therefore, the number of the multiple protrusions can be set according to the needs of the equipment.

[0244] like Figure 31A 、 Figure 31B 、 Figure 32A and Figure 32B As shown, when the guide protrusion 613h also reaches the edge of the groove 615, under the action of the elastic force released by the elastic pushing member 611, the guide protrusion 613h slides quickly along the inclined surface 272, and accordingly, the rotation speed of the counting member 613 is also accelerated. Through the positioning protrusion 613d, the transmission member 62 and the action component 63, finally, the detected member 9 quickly returns to the deviated position from the non-deviated position, and the acceleration requirement of the detected member 9 is realized. At the same time, the detection device 6 realizes high-precision detection.

[0245] In some embodiments, after the detected member 9 is accelerated, it is necessary to return from the deviated position to the non-deviated position again. At this time, the positioning protrusion 613d is configured to disengage from the forced pushing portion 621; on the contrary, in some embodiments, after the detected member 9 is accelerated, the detected member 9 still needs to remain in the deviated position. At this time, the positioning protrusion 613d will be configured to remain in contact with the forced pushing portion 621.

[0246] Furthermore, when the elastic pushing member 611 pushes the counting member 613 toward the housing 2 / detection end, the driving force output portion 6122 and the driving force receiving portion 613c will separate from each other. Figure 32B As shown, along the rotation axis L4, the driving member 612 and the counting member 613 separate from each other, resulting in an interruption in the transmission of driving force between the two. Even if the driving member 612 continues to rotate, the counting member 613 will remain stationary. Accordingly, the transmission member 62, the action component 63, and the detected member 9 will all remain stationary. In some embodiments, the detection device 6 can also be configured such that, upon completion of detection, the elastic pushing member 611 simultaneously pushes the driving member 612 and the counting member 613. At this time, the driving member 612 no longer receives driving force and remains stationary.

[0247] Example 3

[0248] On the basis of the above embodiment, this embodiment continues to optimize the structure of the detection device 6 to further improve the detection accuracy of the detection device and enhance the miniaturization level of the developing box.

[0250] Figure 42 It is a side view of the driving member and the counting member involved in the third embodiment of the present invention after they are combined with each other, observed along a direction perpendicular to the rotation axis of the driving member and the rotation axis of the counting member.

[0251] like Figure 33 As shown, the driving member 612 and the counting member 613 are still configured as two separate components, wherein the driving member 612 still rotates around the rotation axis L4, and the counting member 613 is configured to rotate around the rotation axis L8 intersecting the rotation axis L4. Preferably, the rotation axis L4 and the rotation axis L8 are perpendicular to each other. Through this configuration, the size of the detection device 6 can be reduced along the first direction, and the counting member 613 can be placed along a direction intersecting the first direction according to the overall structure of the developing cartridge.

[0252] like Figure 34 As shown, the driving member 612 is provided with a base 6120, a driving force output member 6128 and a driving force output portion 6122 respectively located on both sides of the base 6120, wherein the driving force input member 6128 is used to receive the driving force of the driving force receiving member 41. Commonly used, the driving force input member 6128 is set to a full-tooth gear, or a cylinder with a rough surface, etc., as long as the driving force input member 6128 can receive the driving force, the driving force output portion 6122 is set to a bevel gear. In this way, the driving force output portion 6122 outputs the driving force. The force can change the direction of rotation, so that the driving force is transmitted from the driving member 612 to the counting member 613; further, the driving member 612 also includes a third abutment portion 6127 arranged on the base 6120, similar to the above-mentioned first abutment portion 275. Preferably, the third abutment portion 6127 is a cantilever arranged on the base 6120, and the third abutment portion 6127 is also provided with the abutment surface and the inclined surface, so that the third abutment portion 6127 can not only prevent the counting member 613 from rotating in the reverse direction, but also will not hinder the forward rotation of the counting member 613.

[0253] Preferably, the driving force output member 6128 is configured as a spur gear having the following parameters: number of teeth: 28, module: 0.8, and pressure angle: 20°; the bevel gear 6122 has the following parameters: gear number: 15, module: 0.9, root radius: 0.2, pressure angle: 20°, and pitch angle: 45°. Specifically, those skilled in the art may appropriately adjust the above parameters according to design requirements to achieve the purpose of the present invention without changing the inventive concept of the present invention.

[0254] In some embodiments, the counting member 613 needs to be delayed. Similar to what is described in the above-mentioned [Delayed Movement of the Counting Member], the toggle portion 4411 is provided in the driving member 612. Accordingly, the counting member 613 is provided with a toggle portion 612c which can be toggled by the toggle portion 4411, which will be described in detail below.

[0255] In some embodiments, at the end of the detection, the detected object 9 also needs to be accelerated and reflected to the detection device 6, such as Figure 34 As shown, the driving member 612 is further provided with a triggering member 6126 for forcing the counting member 613 to accelerate. Correspondingly, the counting member 613 is provided with a triggered member 613q that can be triggered by the triggering member 6126, which will be described in detail below.

[0256] like Figures 35A-35D As shown, the counting member 613 includes a chassis 613a, a coupling portion 613b, a driving force receiving portion 613c and a plurality of protrusions 613d-613f arranged on the chassis 613a, the coupling portion 613b is used to couple the counting member 613 with the housing 2, so that the counting member 613 can rotate around the rotation axis L8 in the direction indicated by r5. Along the rotation direction r5, the positioning protrusion 613d, the first toggle protrusion 613e and the second toggle protrusion 613f are arranged in sequence at intervals; the driving force receiving portion 613c for coupling with the driving force output portion 6122 is arranged on the circumference of the coupling portion 613b. Specifically, the driving force receiving portion 613c is arranged on a portion of the circumferential surface of the coupling portion 613b. The bevel teeth (toothed portion) 612a, along the circumferential direction of the coupling portion 613b, the portion where the bevel teeth 612a are not provided is the tooth-missing portion 612b; further, the counting member 613 also includes a positioning column 613p protruding from the chassis 613a in the opposite direction of the coupling portion 613b. Through the coupling portion 613b and the positioning column 613p, the counting member 613 can be stably positioned in a rotatable manner, and the triggered member 613q is provided on the circumferential surface of the positioning column 613p. Preferably, the triggering member 6126 and the triggered member 613q are both provided as protrusions, that is, the triggering member 6126 is formed to protrude from the base 6120, and the triggered member 613q is formed to protrude from the chassis 613a or the positioning column 613p.

[0257] Preferably, the bevel teeth have 8 teeth, a module of 0.9, a root radius of 0.2, a pressure angle of 20°, a pitch angle of 45°, and the angle corresponding to the toothless portion 612b is 168°. Specifically, those skilled in the art may adjust the above parameters appropriately based on design requirements to achieve the objectives of the present invention without changing the inventive concept of the present invention. More preferably, the transmission ratio between the driving member 612 and the counter member 613 is 1:1.

[0258] In this embodiment, the triggered member 613q and the toggled portion 612c are respectively arranged on both sides of the chassis 613a. In this way, the structure of the counting member 613 is more evenly distributed, and the triggered member 613q and the toggled portion 612c will not interfere with each other during operation.

[0259] Preferably, along the rotation direction r5, the surface (triggered surface) 613q1 of the triggered member 613q for being triggered by the trigger member 6126 is an inclined surface, that is, the tangent of the point where the circle in the rotation direction r5 passes through the triggered surface 613q1 is not perpendicular to the triggered surface 613q1, as shown in FIG. Figure 35C As shown, the triggered surface 613q1 is simplified into a line segment EF, and the line connecting the endpoint E of the line segment EF and the rotation axis L8 and the line connecting the endpoint F and the rotation axis L8 do not coincide. Along the rotation direction r5, the line connecting the endpoint E and the rotation axis L8 is located downstream of the line connecting the endpoint F and the rotation axis L8. In other words, the angle between the tangent and the line segment EF is an acute angle. This design is conducive to the rapid separation of the triggering member 6126 and the triggered member 613q. On the contrary, when the counting member 613 needs to be accelerated for a longer time, the angle between the line segment EF and the tangent can be adjusted. It can be understood that the larger the angle between the line segment EF and the tangent, the later the triggering member 6126 separates from the triggered member 613q. Therefore, the position and shape of the triggered member 613q, especially the triggered surface 613q1, can be set according to the situation where the counting member 613 needs to be accelerated.

[0260] Similar to the above embodiment, the counting member 613 in this embodiment is also provided with a positioning member that can prevent reverse rotation, such as Figure 35A As shown, the counting member 613 also includes a third positioning portion 613d3 and a fourth positioning portion 613d4 provided on the positioning protrusion 613d, and a fifth positioning portion 613m and a sixth positioning portion 613n provided on the positioning column 613p, wherein the third positioning portion 613d3 and the fifth positioning portion 613m are used to position the starting position of the counting member 613, and the fourth positioning portion 613d4 and the sixth positioning portion 613n are used to position the terminal position of the counting member 613. Therefore, the third positioning portion 613d and the fifth positioning portion 613m can be selected to be set, or can be set at the same time, and the fourth positioning portion 613d4 and the sixth positioning portion 613n can be selected to be set, or can be set at the same time.

[0261] Among them, the third positioning portion 613d3 and the fourth positioning portion 613d4 realize the positioning of the counting member 613 by abutting against the transmission member 62 (specifically, the forced pushing portion 621), and the fifth positioning portion 613m and the sixth positioning portion 613n realize the positioning of the counting member 613 by combining with the cover member 24; Figure 35AAs shown, the fifth positioning portion 613m and the sixth positioning portion 613n are both configured as recesses having a vertical surface and an inclined surface. The vertical surface is parallel to the rotation axis L8 and is used to limit the counter 613 from rotating in the reverse direction. The inclined surface is inclined relative to the rotation axis L8 and is used to allow the counter 613 to rotate in the forward direction. Figure 33 As shown, the cover 24 is provided with a cantilever 241 similar to the abutment protrusion 275, and the cantilever is provided with a protrusion (not shown) that can enter the recess. When the counting piece 613 is in the starting position, the protrusion enters the fifth positioning portion 613m, and when the counting piece 613 reaches the terminal position, the protrusion enters the sixth positioning portion 613n.

[0262] Compared with the second embodiment, the acting component 63 in this embodiment is formed integrally with the transmission member 62, and the overall structure of the detection device 6 is simplified. When the transmission member 62 is pulled, the transmission member 62 can more efficiently transmit the acting force to the acting component 63; contrary to the second embodiment, the rotation direction of the acting component 63 and the transmission member 62 will be consistent, that is, when the right side 62b of the transmission member connected to the acting component 63 moves toward the front 53 of the developing box, the acting component 63 causes the detected member 9 to move from the non-deviated position to the deviated position, and when the right side 62b of the transmission member moves toward the rear 54 of the developing box, the acting component 63 causes the detected member 9 to move from the deviated position to the non-deviated position.

[0263] The following describes the detection process of the detection device 6 in conjunction with the accompanying drawings. In order to more clearly show the detection process of the detection device 6, Figure 37A 、 Figure 37B 、 Figure 38A 、 Figure 38B 、 Figure 39A 、 Figure 39B 、 Figures 40A-40D as well as Figures 41A-41D Only the detection device 6 and the detected part 9 are retained.

[0264] like Figure 36A and Figure 36B As shown, when the developing box has just been installed to the predetermined position of the device and has not yet started working, the first indicator portion 273 is in a position opposite to the second indicator portion 6121, and the second dial protrusion 613f of the multiple protrusions provided in the counting member 613 abuts against the third abutting portion 6127. At the same time, the outer surface of the positioning protrusion 613d abuts against the forced pushing portion 621, and the left side 62a of the transmission member is pushed toward the rear 54 of the developing box, and the reset member abutting against the transmission member 62 undergoes elastic deformation. The reaction force applied by the reset member to the transmission member 62 causes the left side 62a of the transmission member to have a tendency to move toward the front 53 of the developing box, but the abutment of the positioning protrusion 613d with the forced pushing portion 621 causes the left side 62a of the transmission member to be maintained Figure 36A The position shown is toward the rear 54 of the developer box.

[0265] Specifically, along the rotation direction r5, the third abutment portion 6127 restricts the downstream of the second shift protrusion 613f, and at the same time, the forced pushing portion 621 restricts the downstream of the positioning protrusion 613d. In this way, the counting member 613 can be maintained in the starting position, and the transmission member 62 is also maintained at the position 62a on the left side of the transmission member toward the rear 54 of the developing box, the detected member 9 is maintained in the deviated position, and the installation of the developing box can be detected by the equipment.

[0266] Furthermore, before the counting member 613 starts working, even if the counting member 613 has a tendency to rotate in the opposite direction, the third positioning portion 613d3 will abut against the forced pushing portion 621, or the fifth positioning portion 613m will abut against the cantilever protrusion provided on the covering member, and the tendency of the counting member 613 to rotate in the opposite direction can be stopped.

[0267] As the driving force receiving member 41 starts to rotate, the driving force input member 6128 in the driving member 612 also starts to rotate after receiving the driving force of the driving force receiving member 41. In the case that the counting member 613 does not need to be delayed, the driving force output portion 6122 will directly combine with the driving force receiving portion 612a; in the case that the counting member 613 needs to be delayed, the driving force output portion 6122 will rotate a predetermined angle so that the toggle portion 4411 starts to abut against the toggle portion 612c, as shown in FIG. Figure 37A and Figure 37B As shown, the driven portion 612 c drives the counting member 613 to rotate around the rotation axis L8 by an angle. When the driving portion 4411 is disengaged from the driven portion 612 c , the driving force output portion 6122 begins to engage with the driving force receiving portion 612 a .

[0268] like Figure 38A and Figure 38B As shown, as the counting member 613 continues to rotate, the positioning protrusion 613d is disengaged from the forced pushing portion 621. Under the action of the reset force released by the reset member 64, the transmission member 62 rotates around the rotation axis L6. The left side 62a of the transmission member moves toward the front 53 of the developing cartridge, and the right side 62b of the transmission member moves toward the rear 54 of the developing cartridge. At the same time, the second rod 92 of the detected member returns from the deviated position to the non-deviated position. Figure 39A and Figure 39B As shown, when the first driving protrusion 613e abuts against the forced pushing portion 621, the left side 62a of the transmission member moves toward the rear 54 of the developing box again, and the right side 62b of the transmission member moves toward the front 53 of the developing box again. At the same time, the reset member 64 abutting against the transmission member 62 is elastically deformed again, and the action component 63 connected to the right side of the transmission member causes the detected member 9 to move from the non-deviated position to the deviated position.

[0269] Subsequently, the second positioning protrusion 613f abuts against the forced pushing portion 621, and the transmission member 62 causes the detected member 9 to move between the deviated position and the non-deviated position again. Figure 40A and Figure 40B As shown, at the end of the detection, after the second positioning protrusion 613f is disengaged from the forced pushing portion 621, under the action of the reset force of the reset member 64, the forced pushing portion 621 is abutted against the positioning protrusion 613d. At this time, the trigger member 6126 is abutted against the triggered surface 613q1. Along the radial direction of the counting member 613, the triggered member 613q is closer to the rotation axis L8 than the multiple protrusions (613d, 613e and 613f). Therefore, when the trigger member 6126 rotates at a constant speed with the driving member 612, the consequence of the triggered member 613q being pushed by the trigger member 6126 is that the rotation speed (linear speed) of the counting member 613 is accelerated. The accelerated rotation speed is relative to the rotation speed of the counting member 613 generated by the driving force output portion 6122 by driving the driving force receiving portion 613c.

[0270] It is understandable that the closer the contact position between the triggering member 6126 and the triggered surface 613q1 is to the rotation axis L8, the more obvious the acceleration phenomenon generated by the counting member 613 is. Preferably, the triggering member 6126 is combined with the root of the triggered surface 613q1 (i.e., the side close to the rotation axis L8), or in other words, combined with Figure 35C Along the radial direction of the counting member 613 , the contact position between the triggering member 6126 and the triggered surface 613q1 is closer to the end point F, which is a point closer to the rotation axis L8 than the end point E.

[0271] Preferably, Figure 40C and Figure 40D As shown, in the final stage of the detection, the moment when the triggering member 6126 contacts the triggered member 613q is later than the moment when the driving force output part 6122 and the driving force receiving part 613c are disengaged. For example, the moment when the triggering member 6126 contacts the triggered member 613q can be the moment when the driving force output part 6122 and the driving force receiving part 613c have just disengaged, or it can be within a predetermined time after the driving force output part 6122 and the driving force receiving part 613c are disengaged.

[0272] like Figure 41A and Figure 41BAs shown, when the triggering member 6126 triggers the triggered member 613q, the driving force output portion 6122 is opposite to the toothed portion 612b, and the counting member 613 continues to rotate in the positive direction around the rotation axis L8. When the triggering member 6126 disengages from the triggered member 613q, the counting member 613 no longer receives the driving force and remains stationary. The fourth positioning portion 613d4 abuts against the forced pushing portion 621, and the protrusion on the covering member enters the sixth positioning portion 613n. The counting member 613 can be maintained in a stationary position, and the possible reverse rotation of the counting member 613 is stopped. Even if the driving member 612 continues to rotate, the driving force will not be transmitted from the driving member 612 to the counting member 613. The left side 62a of the transmission member is pushed toward the rear 54 of the developing box and maintained, and the right side 62b of the transmission member is pushed toward the front 53 of the developing box and maintained. At the same time, the acting component 63 connected to the right side 62b of the transmission member forces the detected member 9 to move from the non-deviated position to the deviated position and maintain it.

[0273] Next, the resetting of the detection device 6 will be described.

[0274] As described above, after the detection device 6 completes the detection, the counting member 613 will remain in a stationary position, and the driving member 612 can be set to always receive the driving force and be in a rotating state, or it can be set to no longer receive the driving force and remain in a stationary state. When the developing box stops working, the position of the driving member 612 is not certain, that is, the position of the second indicator 6121 located on the driving member 612 relative to other components is random.

[0275] After the user adds new developer to the developing cartridge, the detection device 6 needs to be reset to ensure that the developing cartridge can be identified when it is installed in the device again. Therefore, resetting the detection device 6 includes resetting the driving member 612 and resetting the counting member 613.

[0276] The reset of the driving member 612 only needs to be done by rotating the driving member 612 so that the second indicating portion 6121 is opposite to the first indicating portion 273 on the left end cover, but the direction in which the driving member 612 is rotated does not need to be restricted; the reset of the counting member 613 can be achieved by continuing to rotate the counting member in the forward direction, along the rotation direction r5, so that the forced pushing portion 621 returns to the downstream of the third positioning portion 613d3 again. At this time, the forced pushing portion 621 again abuts against the outer surface of the third positioning portion 613d3, and at the same time, the second driving protrusion 613f abuts against the third abutting portion 6127, and the protrusion on the covering member enters the fifth positioning portion 613m.

[0277] Preferably, the rotatable angle of the transmission member 62 around the rotation axis L8 in this embodiment should be controlled within the range of 3°-45°, so as to achieve the ability to accurately move the detected member 9 while reducing the size of the developing box in the plane where the movement trajectory of the transmission member 62 is located. More preferably, the angle is 3.5°-6°.

[0278] Based on the above technical concept, in some embodiments, the transmission member 62 is configured so that along the first direction, the size of the left side 62a of the transmission member is smaller than the size of the right side 62b of the transmission member. This configuration enables the transmission member 62 to form a labor-intensive lever. Therefore, when the left side 62a of the transmission member is toggled by the multiple protrusions, the right side 62b of the transmission member can obtain a larger amount of rotation along the rotation direction of the transmission member 62, which makes it easier to meet the deviation requirements of the detected member 9, thereby making the detection result more accurate.

[0279] As described above, the rotation axis L4 of the driving member 6112 and the rotation axis L8 of the counting member 613 intersect. During the rotation of the driving member 612, the triggering member 6126 arranged in the driving member triggers the triggered member 613q arranged in the counting member 613, thereby realizing the accelerated rotation of the counting member 613. The acceleration of the counting member 613 is different depending on the position where the triggering member 6126 triggers the triggered member 613q. The closer the position where the triggering member 6126 triggers the triggered member 613q is to the rotation axis L8, the greater the acceleration of the counting member 613. This requires that the triggering member 6126 protrudes from the base 6120 to be larger.

[0280] like Figure 42 As shown, along the protruding direction of the trigger member 6126, the distance between the surface of the base 6120 where the trigger member 6126 is arranged and the position of the outer circumferential surface of the positioning column 613p closest to the base 6120 is h3=4.81mm, and the protruding dimension of the trigger member 6126 from the base 6120 is h4. When h3=h4, the counting member 613 can obtain the maximum acceleration, but considering the production error, assembly error and other conditions of parts, the h4 is preferably 4.75mm. According to the inventor's test, when h4=3.5mm, the acceleration obtained by the counting member 613 can basically meet the detection requirements of certain models of developer cartridges. Therefore, the h4 is preferably 3.5mm-4.81mm, preferably 4.75mm; however, in other developer cartridges, the value of h4 may also be less than 3.5mm, and thus, the value of h4 can be freely selected within the range of 0.5mm-4.81mm.

[0281] Figure 43A It is a three-dimensional diagram of the conductive end of the developing cartridge involved in the third embodiment of the present utility model; Figure 43B It is a schematic diagram of some components of the conductive end of the developing cartridge and some components of the detecting device after being exploded according to the third embodiment of the present invention; Figure 43C is a side view when viewed from right to left along a first direction; Figure 44A This is a perspective view of the driving end of the developing cartridge according to the third embodiment of the present invention; Figure 44B It is a schematic diagram of some components of the driving end of the developing cartridge and some components of the detecting device involved in the third embodiment of the present utility model after being exploded; Figure 44C This is a side view of the developing cartridge according to the third embodiment of the present invention when viewed from left to right along a first direction after the left end cover is hidden; Figure 45 This is a perspective view of the driving force receiving member and the intermediate gear involved in the third embodiment of the present utility model; Figure 46 is a cross-sectional view taken along a plane passing through the rotation axis of the driving force receiving member and perpendicular to the second direction; Figure 47 This is a partial exploded schematic diagram of the developing box involved in the third embodiment of the present invention after the driving force transmission component is hidden.

[0282] In the developing box involved in this embodiment, the conductive member 26 includes a first conductive member 261 and a second conductive member 262 which are formed separately. Along the first direction, a movable gap is formed between the first conductive member 261 and the second conductive member 262, so that the extrusion of the conductive member 26 on the power output member in the imaging device is reduced, and the wear of the conductive member 26 and the power output member can be reduced; wherein, the first conductive member 261 is formed by injection molding of a conductive resin, and the second conductive member 262 is formed by bending a metal sheet. The second conductive member 262 can transfer the received power to the first conductive member 261, and at the same time, the second conductive member 262 also transfers the received power to the developer regulating member 29.

[0283] As described above, along the third direction, the powder filling port 2a3 is arranged on the same side as the acting component 63, and the powder filling port 2a3 is located below the acting component 63. For the transmission member 62 that rotates about the rotation axis L6 intersecting the first direction, when the acting component 63 rotates about the rotation axis L6 together with the transmission member 62 and is observed along the first direction, the movement trajectory of the acting component 63 does not coincide with the powder filling port 2a3, or in other words, the movement trajectory of the acting component 63 is located outside the powder filling port 2a3. At this time, regardless of whether the acting component 63 is set to swing in the left-right direction or in the front-back direction, the stationary position of the acting component 63 will not hinder the replenishment of developer through the powder filling port 2a3. Therefore, the free end of the powder filling port 2a3 is designed to be higher. Finally, the powder filling port 2a3 is sealed by the sealing cover 2a4. Furthermore, the conductive end of the developer box does not need to be provided with a right end cover 28. Along the first direction, the right surface 22 / acting component 63 / sealing cover 2a4 are directly exposed to the outside. This design will make the right structure of the developer box simpler. It not only eliminates the right end cover 28, but also allows the user to quickly replenish the developer through the powder filling port 2a3. At this time, the second forced push portion 2b2 is arranged on the right side of the shell 2.

[0284] like Figure 44A 、 Figure 44B and Figure 44C As shown, the developing box further includes a protective cover 105 combined with the shell 2. When the developing box is assembled, the developing member 31 can be effectively protected by installing the protective cover 105 onto the shell 2.

[0285] Furthermore, the developing box also includes a support column 2a5 for supporting the driving force receiving member 41 and a left bracket 2f for supporting the rotating shaft of the developing member 31 and the rotating shaft of the powder feeding member 32. Preferably, the support column 2a5 extends from the left surface 21 of the shell 2 along the first direction toward the direction away from the developer chamber 10 (that is, one end of the first direction); the left bracket 2f is provided with a first through hole 2f1 and a second through hole 2f2 for the rotating shaft of the developing member and the rotating shaft of the powder feeding member to pass through respectively.

[0286] Along the first direction, the driving force receiving member 41 is located to the left of the left bracket 2f. The driving force receiving member 41 in this embodiment will generate a thrust toward the housing 2 during the rotation process. Preferably, the driving force receiving member 41 abuts against the left bracket 2f (e.g., Figure 46 As shown), the left bracket 2f is made of wear-resistant material (such as POM material) to reduce the wear of the driving force receiving member 4 during the rotation process. More preferably, the left bracket 2f is also provided with a third through-hole 2f3 for the support column 2a5 to pass through.

[0287] Furthermore, the driving force transmission component 4 further includes an intermediate gear 46 combined with the driving force receiving member 41, and the intermediate gear 46 is used to transmit the driving force. Figure 45 As shown, the intermediate gear 46 is formed integrally with the driving force receiving member 41, and thus the intermediate gear 46 can also be regarded as a part of the driving force receiving member 41; a driving force transmitting portion 461 is formed inside the intermediate gear 46, and an insertion gap 462 is formed between the driving force transmitting portion 461 and the intermediate gear 46 along the radial direction of the intermediate gear 46, as shown in FIG. Figure 46 As shown, when the driving force receiving member 41 is installed, the support column 2a5 enters the insertion gap 462, and the driving force transmitting portion 461 is combined with the driving rod 89, and the driving rod 89 is used to drive the stirring member 33 movably installed in the developer chamber 10, so that when the driving force receiving member 41 rotates, the driving rod 89 can be driven to rotate synchronously.

[0288] like Figure 44B As shown, along the first direction, the idler wheel 45 also includes a first protrusion 451 and a second protrusion 452 extending in opposite directions respectively. The first protrusion 451 cooperates with the support hole 276 provided in the left end cover 27, and the second protrusion 452 cooperates with the housing 2. Therefore, the idler wheel 45 can be simply positioned and stably supported.

[0289] In the driving force transmission assembly 4, the intermediate gear 46 is used to transmit the driving force of the driving force receiving member 41, the developing member driving gear 42 is meshed with the intermediate gear 46 and drives the developing member 31 to rotate, the powder feeding member driving gear 43 is meshed with the intermediate gear 46 and drives the powder feeding member 32 to rotate, the idler gear 46 is meshed with the intermediate gear 46 and transmits the driving force to the stirring member gear 44, and the stirring member gear 44 serves as the driving source of the driving member 612. Preferably, the intermediate gear 46, the developing member driving gear 42, the feeding member driving gear 43 and the intermediate gear 46 are meshed with each other and drive the powder feeding member 32 to rotate. The module of at least one of the powder member driving gear 43 and the idler gear 45 is smaller than the module of at least one of the stirring member gear 44, the driving member 612 and the counting member 613. Therefore, the driving force of the driving force receiving member 41 can be stably transmitted to the developing member 31 and the powder feeding member 32. For the stirring member gear 44, the driving member 612 and the counting member 613, as long as the driving force can be transmitted, even if the module of the stirring member gear 44, the driving member 612 and the counting member 613 becomes larger, it will not affect the detection of the detection device 6.

[0290] In this embodiment, the chip assembly 11 is arranged on the same side as the counting member 613, so that the structure of the conductive end can be simplified; the chip assembly 11 includes a conductor A92, a pushing member A93, a movable member A94 and a chip 7, and the chip 7 is fixedly mounted on the movable member A94. The conductor A92 is used to electrically connect the chip 7 and the contact pin in the imaging device. Before the developing box is installed, the conductor 92 is not connected to the chip 7. As the developing box is installed, the movable member A94 is abutted, and the pushing member A93 is elastically deformed, and then the chip 7 is electrically connected to the conductor A92. When the developing box reaches the predetermined position of the imaging device, the conductor A92 is electrically connected to the contact pin, and thus, the conductor A92 electrically connects the contact pin and the chip 7; when the movable member A94 is no longer abutted, the pushing member A93 releases the pushing force, and the movable member A94 drives the chip 7 away from the conductor A92, and the chip 7 is arranged to be movable with the movement of the movable member A94, so that the wear of the chip 7 can be reduced.

[0291] Along the third direction, the driving force receiving member 41 / support column 2a5 / rotation axis L2 is located above the conductor A92 / chip 7, so that the influence of the vibration generated when the driving force receiving member 41 is working on the conductor A92 / chip 7 can be reduced. Preferably, along the third direction, the driving force receiving member 41 / support column 2a5 / rotation axis L2 and the conductor A92 / chip 7 are respectively located at the two ends of the shell 2, so that the influence of the vibration on the conductor A92 / chip 7 can be further reduced.

[0292] As described above, in the detection device 6, the rotation axes of the driving member 612 and the counting member 613 intersect, and the driving force is transmitted between the driving member 612 and the counting member 613 through the bevel gear. Preferably, the driving member 612 and the counting member 613 are positioned on the same base, such as Figure 47 As shown, the upper shell 2a is provided with a driving member support shaft 65 and a counting member support shaft 66 for supporting the driving member 612 and the counting member 613 respectively. The extension direction of the driving member support shaft 65 and the extension direction of the counting member support shaft 66 intersect. Therefore, the upper shell 2a is the base for supporting the driving member 612 and the counting member 613, so that the driving member 612 and the counting member 613 can be precisely combined.

[0293] It is feasible that the driving member support shaft 65 and the counting member support shaft 66 can also be provided on the lower housing 2b at the same time. In this case, the driving member 612 and the counting member 613 will be supported by the lower housing 2b at the same time.

[0294] Example 4

[0295] Figure 48 1 is a diagram showing a state in which the left end cover, the driving force receiving member and the chip of the developing cartridge according to the fourth embodiment of the present invention are separated from the housing; Figure 49 It is a side view of the developing box involved in the fourth embodiment of the present invention observed from left to right along the first direction.

[0296] In this embodiment, the chip assembly 11 is simplified to include only the chip 7. Figure 48 As shown, the shell 2 is provided with a chip holder 19 for supporting the chip 7. Specifically, along the first direction, the chip holder 19 extends from the shell 2 toward a direction away from the shell 2. Similarly, along the third direction, the chip holder 19 is located below the driving force receiving member 41. Accordingly, along the third direction, the chip 7 is also located below the driving force receiving member 41 / support column 2a5 / rotation axis L2; ​​preferably, the chip holder 19 is formed integrally with the shell 2, and optionally, the support column 2a5 is also formed integrally with the shell 2, so that the installation steps of the chip holder 19 and the support column 2a5 can be omitted.

[0297] In some embodiments, along the first direction, the chip bracket 19 includes a first bracket 191 arranged on the shell 2 and a second bracket 192 arranged on the left end cover 27. The size of the first bracket 191 in the first direction and the size of the second bracket 192 in the first direction are both smaller than the size of the chip 7 in the first direction, but the sum of the size of the first bracket 191 in the first direction and the size of the second bracket 192 in the first direction is not less than the size of the chip 7 in the first direction. In this way, the chip 7 can be easily installed and disassembled, and the chip 7 can also be stably supported by the chip bracket 19.

[0298] Example 5

[0299] Figure 50 This is a perspective view of the developing cartridge according to the fifth embodiment of the present invention before being combined with the power output component in the imaging device; Figure 511 is a schematic diagram of a state in which the conductive member of the developing cartridge according to the fifth embodiment of the present invention is separated from the housing; Figure 52A This is a side view of the conductive member of the developing cartridge according to the fifth embodiment of the present invention, viewed along the third direction, after being combined with the power output member in the imaging device; Figure 52B This is a side view of the conductive member of the developing cartridge according to the fifth embodiment of the present invention, viewed along a first direction, after being combined with the power output member in the imaging device; Figure 53 This is a side view of the developing box involved in the fifth embodiment of the present invention after another conductive member is installed, observed along the third direction.

[0300] Based on the above embodiment, this embodiment focuses on describing the structure of the conductive member 26 and its relative position in the developer box.

[0301] like Figure 50 As shown, along the second direction (the installation and disassembly direction of the developing box 1), the imaging device is provided with a first power output member 101 and a second power output member 102 spaced apart from each other. In the existing developing box, the first power output member 101 is used to supply power to the powder feeding member 32, and the second power output member 102 is used to supply power to the developing member 31. In the forward direction (the front 53 of the developing box), the second power output member 102 is located downstream of the first power output member 101.

[0302] In order to enable the developing cartridge 1 to stably receive power, this embodiment adopts a method in which the first power output component 101 supplies power to the developing component 31 and the powder feeding component 32 simultaneously. As shown in the figure, the conductive member 26 includes a main body 26a and a power input portion 26b, a developing member power supply portion 26c and a powder feeding member power supply portion 26d arranged on the main body 26a. The conductive member 26 is fixedly connected to the shell 2. In practice, the conductive member 26 can be fixedly connected to the shell 2 through at least any part thereof, for example, the main body 26a is fixedly connected to the shell 2, or the power input portion 26b is fixedly connected to the shell 2, or the developing member power supply portion 26c is fixedly connected to the shell 2, or the powder feeding member power supply portion 26d is fixedly connected to the shell 2; the power input portion 26b is used to electrically connect to the first power output member 101 to receive power, the developing member power supply portion 26c is used to supply the power received by the power input portion 26b to the developing member 31, and the powder feeding member power supply portion 26d is used to supply the power received by the power input portion 26b to the powder feeding member 32.

[0303] In some embodiments, the conductive member 26 is integrally formed of a conductive material. For example, the conductive member 26 is integrally formed by injection molding of a conductive plastic, or integrally formed by pressing a conductive metal sheet.

[0304] In some embodiments, the conductive member 26 is formed separately, and the power input portion 26b, the developing member power supply portion 26c and the powder feeding member power supply portion 26d are made of the aforementioned conductive material, and the power input portion 26b is electrically connected to the developing member power supply portion 26c and the powder feeding member power supply portion 26d at the same time through a conductive connector. In this way, the power received by the power input portion 26b can be simultaneously supplied to the developing member power supply portion 26c and the powder feeding member power supply portion 26d, and then supplied to the developing member 31 and the powder feeding member 32 by the developing member power supply portion 26c and the powder feeding member power supply portion 26d respectively; preferably, the main body 26a is made of conductive material, thereby, the installation of the conductive connector can be omitted, and the poor conductivity defects between the components of the conductive member 26 caused by assembly errors or material deformation and other factors can be avoided.

[0305] like Figure 51 As shown, the developing part power supply portion 26c supplies power to the developing part 31 by being electrically connected to the developing part shaft 311 of the developing part 31, and the powder feeding part power supply portion 26d supplies power to the powder feeding part 32 by being electrically connected to the powder feeding part shaft 321 of the powder feeding part 32. The electrical connection method can be direct contact or indirect contact, and can be contact with the circumferential surface of the developing part shaft 311 / powder feeding part shaft 321, or can be contact with the longitudinal end of the developing part shaft 311 / powder feeding part shaft 321.

[0306] like Figure 52A As shown, when the developer cartridge 1 reaches the predetermined installation position of the imaging device, along the first direction, the first power output member 101 contacts the conductive member 26 / power input portion 26b at point D, but the second power output member 102 is not electrically connected to the conductive member 26. Along the first direction, the developer power supply portion 26c has a first exposed surface 26c1 facing the right 52. Preferably, the first exposed surface 26c1 is arranged to be inclined relative to the second direction, and along the second direction, the first exposed surface 26c1 gradually moves away from the housing 2 from the front to the rear. This design can make it easier to install the developer cartridge 1 in the imaging device.

[0307] like Figure 53 As shown, along the first direction, the power input portion 26b also has a second exposed surface 26b1 facing the right 52, and the second exposed surface 26b1 is used to contact the first power output member 101 at point D. As a deformation mode of the conductive member 26, the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear. Similarly, this design can also make it easier for the developer box 1 to be installed on the imaging device, and can prevent the first power output member 101 and the conductive member 26 from interfering with each other and causing damage to both.

[0308] As described above, the action component 63 for moving the detected member 9 in the imaging device is exposed toward the detection end. The action component 63 can move the detected member 9 by rotation or translation, and the transmission member 62 for driving the action component 63 can also move by rotation or translation.

[0309] like Figure 52B As shown, when the developing box 1 is observed along the first direction, a straight line M is drawn parallel to the first direction. Along the third direction, the rotation axis L1 of the developing member 31, the contact point D and the free end of the acting component 63 are projected on the straight line M at points T1, T2 and T3 respectively. Along the second direction, the distance between point T1 and point T2 is s1, and the distance between point T2 and point T3 is s3, s1>s3, that is, the contact point D is closer to the free end of the acting component 63, so that the influence of the vibration of the developing member 31 on the contact point D is reduced, that is, the first power output member 101 can stably output power to the power input part 26b.

[0310] It should be noted that the free end of the action component 63 refers to the portion of the action component 63 used to move the detected component 9 to complete the detection.

[0311] When the transmission member 62 drives the acting component 63 in a rotational manner, the rotation axis L6 of the transmission member 62 intersects the straight line M at point T4. Along the second direction, the distance between point T2 and point T4 is s2, s1>s2, that is, the contact point D is closer to the free end of the acting component 63, so that the influence of the vibration of the developing member 31 on the contact point D is reduced; when the transmission member 62 drives the acting component 63 in a translational manner, the point T4 is the projection of the midpoint of the transmission member 62 in the second direction dimension on the straight line M.

[0312] During the operation of the developing box, compared with the vibration caused by the interaction force between the developing member 31 and the photosensitive drum, the transmission member 62 and the acting component 63 ultimately only need to move the detected member 9, so that the vibration that may be generated by the transmission member 62 and the acting component 63 is smaller. Along the second direction, the contact point D is closer to the acting component 63 / transmission member 62, which is more conducive to ensuring that the first power output member 101 outputs power stably to the power input part 26b.

[0313] Therefore, this embodiment can achieve the following beneficial effects:

[0314] 1. Along the second direction, compared with the distance between the contact point D between the first power output member 101 and the conductive member 26 and the acting component 63 / transmission member 62, the distance between the contact point D between the first power output member 101 and the conductive member 26 and the rotation axis L1 of the developing member 31 is larger, which is beneficial to reducing the impact of the vibration of the developing member 31, making the electrical connection between the first power output member 101 and the conductive member 26 / power input part 26b more stable.

[0315] 2. As described above, the developing member 31 transports the developer toward the photosensitive drum. During this process, a small amount of developer will float away from the developing member 31 and the photosensitive drum. It can be seen that in point 1, the setting away from the developing member 31 can also reduce the risk of the developer floating onto the power input part 26b, thereby reducing the impact of the developer on the electrical connection between the first power output member 101 and the conductive member 26 / power input part 26b, ensuring that the conductive member 26 / power input part 26b stably receives power.

[0316] 3. Along the first direction, the conductive member 26 is arranged at the detection end rather than the driving end. When the developing box is working, the vibration generated by the driving force transmission component 4 at the driving end has less influence on the electrical connection between the first power output member 101 and the conductive member 26.

[0317] 4. Based on point 3, the detection end is not provided with a transmission gear, so that the first power output element 101 and the conductive element 26 can be electrically connected more stably.

[0318] 5. Such as Figure 52B As shown, when observed along the first direction, the second power output member 102 is located within the projection range of the driving force receiving member 41 at the detection end, while the first power output member 101 is located outside the projection range. It can be seen that the driving force receiving member 41 has a smaller impact on the electrical connection between the first power output member 101 and the power input member 26 when working.

[0319] 6. As described above, the powder feeding member 32 is used to supply the developer to the developing member 31. Generally, the voltage applied to the powder feeding member 32 is higher than the voltage applied to the developing member 31, that is, the voltage output by the first power output member 101 is higher than the voltage output by the second power output member 102. When the conductive member 26 is used to receive the power output by the first power output member 101, the voltage required by the powder feeding member 32 can be guaranteed first. Even if there is impedance in the main body 26a or the conductive connecting member, the voltage delivered to the developing member 31 can also meet the development requirements of the developing member 31.

[0320] Accordingly, a voltage reducing element may be provided between the power input portion 26 b and the developing device power supply portion 26 c to ensure that the developing device 31 can receive an appropriate voltage.

[0321] On the contrary, when the conductive member 26 is used to receive the power output by the second power output member 102, since the voltage originally output by the second power output member 102 is lower than the voltage required by the powder feeding member 32, and the impedance of the main body 26a or the conductive connecting member is added, the voltage received by the powder feeding member 32 will be even lower, which will be detrimental to the normal operation of the powder feeding member 32; in this way, although the powder feeding member 32 can obtain a suitable voltage by setting a boosting element in the conductive member, it is obvious that the bucking element has lower cost and is easier to install.

[0322] Example 6

[0323] Figure 54 1 is a schematic diagram of a state where the conductive member of the developing cartridge according to the sixth embodiment of the present invention is separated from the housing.

[0324] like Figure 54 As shown, the conductive member 26 still includes a main body 26a and a power input portion 26b and a developing member power supply portion 26c arranged on the main body 26a. The conductive member 26 is fixedly connected to the shell 2. The power input portion 26b is used to electrically connect to the first power output member 101 to receive power. The developing member power supply portion 26c is used to supply the power received by the power input portion 26b to the developing member 31. Specifically, the developing member power supply portion 26c is electrically connected to the developing member shaft 311 to supply power to the developing member 31. In this embodiment, the powder feeding member 32 is not supplied with power. Therefore, the conductive member 26 does not need to be provided with the above-mentioned powder feeding member power supply portion 26d for electrically connecting to the powder feeding member shaft 321. Finally, the structure of the conductive member 26 is simplified.

[0325] Further, continue as Figure 54 As shown, the powder feeding member 32 is located inside the shell 2, and along the left and right directions, the powder feeding member 32 does not exceed the right surface 22 of the shell 2, so that the conductive member 26 will not be electrically connected to the powder feeding member 32 / powder feeding member shaft 321; in some embodiments, the powder feeding member 32 can also be configured to pass through the right surface 22, but the conductive member 26 is still not electrically connected to the powder feeding member 32 / powder feeding member shaft 321.

[0326] As described above, since the voltage output by the first power output element 101 is higher than the voltage output by the second power output element 102, when the conductive element 26 is used to receive power from the first power output element 101, even if the developing box 1 is in a harsh environment, the charging performance of the developer is reduced, but the developing element 31 can obtain a higher voltage, and a greater electric field force can be generated between the developing element 31 and the photosensitive drum. Therefore, the developer can smoothly reach the surface of the photosensitive drum from the surface of the developing element 31, and the deterioration of the development quality can be effectively suppressed.

[0327] Based on the inventive concept, when the voltage applied to the developing member 31 does not change, the charging performance of the developer can be improved by changing the physical and chemical characteristics of the developer, so that the developer can smoothly reach the surface of the photosensitive drum from the surface of the developing member 31.

[0328] Similar to the fifth embodiment, the power input portion 26b in this embodiment also has the second exposed surface 26b1, and the second exposed surface 26b1 can also be set to be inclined relative to the second direction. Along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear, which can also prevent the first power output component 101 and the conductive component 26 from interfering with each other and causing damage to both.

[0329] Example 7

[0330] Figure 55 1 is a perspective view of a stirring member according to a seventh embodiment of the present invention after being installed in a developing cartridge.

[0331] The stirring member 33 is configured to reciprocate in a direction roughly parallel to the second direction. As shown in the figure, the stirring member 33 includes a frame 331 and a powder feeding plate 332 arranged on the frame 331. At the same time, the frame 331 is connected to the shell 2 through an elastic member 16. As the drive rod 89 rotates, the frame 331 is pushed by the thrust applied by the force-applying portion 893 (such as a cam) provided on the drive rod 89 and moves roughly in the second direction toward the direction away from the developing member 31 (the direction close to the handle 23). The elastic member 16 elastically deforms and accumulates elastic force. When the force-applying portion 893 no longer applies force to the frame 331, the elastic member 16 releases the elastic force and causes the frame 331 to move roughly in the second direction toward the direction close to the developing member 31 (the direction away from the handle 23). When the stirring member 33 collides with the drive rod 89, the powder feeding plate 332 will shake, and the developer located above the powder feeding plate 332 will fall. The powder feeding plate 332 transports the developer away from the developing member 31 toward the direction close to the developing member 31.

[0332] Furthermore, the developing box 1 also includes a buffer member 34 arranged on the stirring member 33. When the buffer member 34 moves in the direction close to the developing member 31 along with the stirring member 33, the noise generated when the buffer member 34 collides with the driving rod 89 can be reduced. Preferably, along the second direction, the buffer member 34 is opposite to the force-applying portion 893. In this way, when the force-applying portion 893 applies thrust to the stirring member 33, the noise of the collision between the force-applying portion 893 and the stirring member 33 can also be reduced. At the same time, the abnormal noise generated when the stirring member 33 shakes can also be reduced.

[0333] The buffer member 34 can be combined with the stirring member 33 by bonding, welding, snapping, etc. The buffer member 34 is preferably an elastic member. For example, at least a part of the buffer member 34 is configured as a sponge, silicone, a spring, etc.

[0334] like Figure 55 As shown, more preferably, the buffer member 34 is combined with the stirring member 33 in a snap-fit ​​manner, and the frame 331 is provided with a mounting portion 333, and at least a portion of the buffer member 34 is accommodated by the mounting portion 333. For example, a snap-fit ​​groove 341 is provided on the buffer member 34, and correspondingly, a snap-fit ​​protrusion 334 that cooperates with the snap-fit ​​groove 341 is provided on the mounting portion 333. At the same time, the buffer surface 342 of the buffer member 34 faces the driving rod 89.

[0335] In addition, compared with the way that the buffer member 34 is pasted and installed on the stirring member 33, the way in which the engaging groove 341 and the engaging protrusion 334 cooperate can ensure that the buffer member 34 is installed more conveniently and stably, and the installation position of the buffer member 34 can be precisely controlled.

[0336] Example 8

[0337] Figure 56 1 is a schematic diagram of a state in which the conductive member of the developing cartridge according to the eighth embodiment of the present invention is separated from the housing; Figure 57 It is a side view of the developing box involved in the eighth embodiment of the present invention after the conductive member is installed, observed along the third direction.

[0338] In this embodiment, the conductive member 26 still includes a main body 26a and a power input portion 26b and a powder feeding member power supply portion 26d arranged on the main body 26a. The conductive member 26 is fixedly connected to the shell 2. The power input portion 26b is used to electrically connect to the first power output member 101 or the second power output member 102 to receive power. The powder feeding member power supply portion 26d is used to supply the power received by the power input portion 26b to the powder feeding member 32. Specifically, the powder feeding member power supply portion 26d is electrically connected to the powder feeding member shaft 321 to supply power to the powder feeding member 32. In this embodiment, the developing member 31 is not directly supplied with power, that is, the developing member 31 does not need to be directly electrically connected to the first power output member 101 or the second power output member 102, but is supplied with power by the powder feeding member 32. Therefore, the conductive member 26 does not need to be provided with the above-mentioned developing member power supply portion 26c for electrically connecting to the developing member shaft 311. Finally, the structure of the conductive member 26 is simplified.

[0339] like Figure 56As shown, the powder feeding member shaft 321 is exposed from the right surface 22 of the shell, and the developing member 31 is located inside the shell 2. Along the left and right directions, the developing member 31 does not exceed the right surface 22 of the shell 2. In this way, the conductive member 26 will not be electrically connected to the developing member 31 / developing member shaft 311; in some embodiments, the developing member 31 can also be configured to pass through the right surface 22, but the conductive member 26 is still not electrically connected to the developing member 31 / developing member shaft 311.

[0340] like Figure 3 As shown, the developing member 31 further includes a developing layer 312, and the powder feeding member 32 further includes a powder feeding layer 322, wherein the developing layer 312 is further away from the developing member rotation axis L1 than the circumferential surface of the developing member shaft 311, and the powder feeding layer 322 is further away from the powder feeding member rotation axis than the circumferential surface of the powder feeding member shaft 321. The developing layer 312 and the powder feeding layer 322 are in contact with each other. Generally, the developing layer 312 and the powder feeding layer 322 are made of elastic material. In this embodiment, when the developing member 31 is not directly supplied with electricity, the powder feeding layer 322 and the developing member are in contact with each other. Layer 312 is preferably made of an elastic conductive material. For example, the powder feeding layer 322 and the developing layer 312 are made of conductive sponge / rubber, etc. In this way, after the powder feeding part 32 is supplied with electricity, an electric field force will be formed between the surface of the powder feeding part 32 and the surface of the developing part 31. The developer on the surface of the powder feeding part 32 can reach the surface of the developing part 31 from the surface of the powder feeding part 32 under the action of the electric field force. At the same time, the electricity supplied to the powder feeding part 32 will be transmitted to the developing layer 312 through the powder feeding layer 322, so that the developing part 31 is also supplied with electricity.

[0341] Furthermore, when the powder feeding member 32 is supplied with electricity, the developer located on the surface of the powder feeding member 32 will also be charged, thereby forming an electric field force between the developer on the surface of the powder feeding member 32 and the surface of the developing member 31. Under the action of this electric field force, the developer can more easily reach the surface of the developing member 31 from the surface of the powder feeding member 32.

[0342] It can be seen that in this embodiment, not only the powder feeding layer 322 can serve as a component for supplying power to the developing member 31 , but the developer located between the developing member 31 and the powder feeding member 32 can also serve as a component for supplying power to the developing member 31 .

[0343] Based on the inventive concept of the embodiment of the utility model, the developing member 31 and the powder feeding member 32 can be any one of the following two specific structures:

[0344] In some embodiments, along the first direction, the developing member shaft 311 passes through the developing layer 312, and the powder feeding member shaft 321 passes through the powder feeding layer 322. At this time, the developing layer 312 covers at least a portion of the circumferential surface of the developing member shaft 311, and the powder feeding layer 322 covers at least a portion of the circumferential surface of the powder feeding member shaft 321.

[0345] In some embodiments, along the first direction, the developing member shaft 311 does not pass through the developing layer 312, and the powder feeding member shaft 321 does not pass through the powder feeding layer 322. At this time, the developing layer 312 covers a portion of the circumferential surface of the developing member shaft 311, or the developing layer 312 does not cover the circumferential surface of the developing member shaft 311, the developing member shaft 311 protrudes from the longitudinal end surface of the developing layer 312, and the powder feeding layer 322 covers a portion of the circumferential surface of the developing member shaft 321, or the powder feeding layer 322 does not cover the circumferential surface of the powder feeding member shaft 321, and the powder feeding member shaft 321 protrudes from the longitudinal end surface of the powder feeding layer 322.

[0346] In particular, when the power input part 26b is electrically connected to the first power output part 101, the developing part 31 will be able to receive a voltage higher than the predetermined voltage. Even if the processing box 1 is in a humid, high-temperature and high-pressure environment, the charge of the developer reaching the surface of the developing part 31 can be kept within a reasonable range. As a result, the deterioration of the development quality of the processing box 1 can be effectively suppressed.

[0347] Same as the above embodiment, Figure 57 As shown, the power input portion 26b has a second exposed surface 26b1 facing the right 52, and the second exposed surface 26b1 contacts the first power output member 101 / the second power output member 102 at point D. Preferably, the second exposed surface 26b1 is arranged to be inclined relative to the second direction, and along the second direction, the second exposed surface 26b1 gradually moves away from the shell 2 from the front to the rear. Similarly, this design can also make it easier for the developer box 1 to be installed to the imaging device, and can prevent the first power output member 101 and the conductive member 26 from interfering with each other and causing damage to both.

[0348] Embodiment 9

[0349] Figure 58 1 is a schematic diagram of a state in which the conductive member of the developing box involved in the ninth embodiment of the present invention is separated from the shell.

[0350] This embodiment continues to provide a structure for supplying power to the rotating member 3, such as Figure 58As shown, the conductive member 26 in this embodiment includes a developing member power input portion 26b2, a powder feeding member power input portion 26b3 and a power output portion 26e, wherein the developing member power input portion 26b2 is used to combine with the second power output member 102 to receive the power output by the second power output member 102, the powder feeding member power input portion 26b3 is used to combine with the first power output member 101 to receive the power output by the first power output member 101, and the power output portion 26e is used to simultaneously supply the power received by the developing member power input portion 26b2 and the power received by the powder feeding member power input portion 26b3 to any one of the developing member 31, the powder feeding member 32 and the developer regulating member 29, and when the power output by the power output portion 26e is supplied to the powder feeding member 32 or the developer regulating member 29, the powder feeding member 32 or the developer regulating member 29 then supplies power to the developing member 31.

[0351] In a deformable manner, the power output portion 26e can also be used to simultaneously supply the power received by the developing part power input portion 26b2 and the power received by the powder feeding part power input portion 26b3 to at least one of the developing part 31, the powder feeding part 32 and the developer regulating part 29.

[0352] This power supply method has the following beneficial effects:

[0353] 1. In this solution, the power output by the first power output element 101 and the power output by the second power output element 102 are simultaneously received by the conductive element 26 and output by the conductive element 26 to any one of the developing element 31, the powder feeding element 32 and the developer regulating element 29. Compared with the solution in which the first power output element 101 or the second power output element 102 is in contact with the conductive element 26, the current output by the conductive element 26 in this solution is larger. As a result, the power obtained by the developing element 31, the powder feeding element 32 or the developer regulating element 29 is also greater, which can ensure that the development quality remains good.

[0354] 2. Compared with the conductive member 26 outputting power to the developing member 31, when the conductive member 26 outputs power to the developer regulating member 29 or the powder feeding member 32, along the second direction, the power output portion 26e is further away from the contact position between the developing member 31 and the photosensitive member. Therefore, during the operation of the developing box 1, the vibration generated between the developing member 31 and the photosensitive member has less influence on the power output portion 26e.

[0355] 3. Compared with the conductive member 26 directly contacting the developing member shaft 311, when the conductive member 26 outputs electricity to the developer regulating member 29 or the powder feeding member 32, since the developing member 32 and the developer regulating member 29 are both in direct contact with the outer surface of the developing member 31, the electricity output by the powder feeding member 32 or the electricity output by the developer regulating member 29 can be directly transmitted to the developing member 31, and the power loss is smaller.

[0356] The developing box 1 further includes a right bracket 2g for supporting the developing member 31. The conductive member 26 can be formed integrally with the right bracket 2g or separately. Figure 58 The structure in which the conductive member 26 and the right bracket 2g are formed separately is shown.

[0357] Example 10

[0358] Figure 59 is a perspective view of a developing cartridge according to a tenth embodiment of the present invention; Figure 60 1 is a schematic diagram of a state in which the left end cover, the chip connecting assembly, and the shell of the developing cartridge involved in the tenth embodiment of the present utility model are separated; Figure 61A This is a side view of the chip connection assembly according to the tenth embodiment of the present invention when it is not connected to the chip, with the left end cover hidden, viewed from the driving end toward the conductive end along the first direction; Figure 61B This is a side view of the chip connecting component involved in the tenth embodiment of the present invention when connected to the chip, after hiding the left end cover, observed along the first direction from the driving end to the conductive end.

[0359] Based on the above embodiment, this embodiment further introduces the chip component 11, which is the same as the first embodiment. Figure 59 and Figure 60 As shown, the chip assembly 11 in this embodiment also includes a conductor A92, a pushing member A93, a movable member A94 and a chip 7, wherein the working process of each component in the chip assembly 11 is the same as that in the first embodiment and will not be repeated here. The conductor A92, the pushing member A93 and the movable member A94 form at least a part of the chip connection assembly. Preferably, the chip assembly 11 also includes a pressing member A98 for preventing the conductor A92 from falling off.

[0360] The difference from the first embodiment is that the chip assembly 11 is arranged on the housing 2, as shown in FIG. Figure 59 As shown, the developing box 1 also includes a support member 2a arranged on the shell 2, and the chip assembly 11 is supported by the support member 2a. Specifically, at least the movable member A94 is supported by the support member 2a, and the chip 7 can move with the movable member A94; the conductor A92 has a first contact portion A921 for contacting with a contact pin in the device and a second contact portion A922 for contacting with the chip electrical contact 72. Hereinafter, the chip electrical contact 72 is arranged on a surface of the substrate 71.

[0361] Figure 61A and Figure 61BThe developing cartridge 1 is in a state of being mounted on the drum frame or being mounted on the device. At this time, the moving direction of the movable member A94 is neither perpendicular nor parallel to the surface of the substrate 71 on which the chip electrical contacts 72 are provided, and the chip 7 can move with the movable member A94. Preferably, the extending direction of the surface is parallel to the moving direction of the movable member A94. Therefore, when the movable member A94 moves from Figure 61A The position shown is toward Figure 61B During the position movement shown, the surface may be pressed against the second contact portion A922 , thereby enabling the second contact portion A922 to form a stable electrical contact with the chip electrical contact 72 .

[0362] Example 11

[0363] Figure 62 This is a three-dimensional diagram of the developing cartridge according to the eleventh embodiment of the present invention with the left end cover hidden; Figure 63 It is a side view of the chip connection assembly involved in the eleventh embodiment of the present invention when the movable part is in the first position and after the left end cover is hidden, observed along the first direction from the driving end to the conductive end.

[0364] Similar to the tenth embodiment, the chip assembly 11 in this embodiment is also arranged on the housing 2, but the position of the chip 7 in the movable member A94 in this embodiment is different from that in the tenth embodiment, as shown in FIG. Figure 63 As described, the extension direction of the surface of the substrate 71 on which the chip electrical contact 72 is provided is not parallel to the movement direction of the movable part A94. Along the third direction, the surface is located below the second contact portion A922. In this way, when the chip 7 moves upward with the movable part A94, the second contact portion A922 and the chip electrical contact 72 can form a stable electrical contact.
