[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments described below are not isolated from each other, and those skilled in the art can combine the structures of the following embodiments with each other according to design requirements.

[0037] Example 1

[0038] [Overall structure of the developer cartridge]

[0039] 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.

[0040] 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.

[0041] 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.

[0042] The driving force receiving member 41 includes a force-bearing body 41a and a transmitting body 41b that are combined with each other. The force-bearing body 41a is used to receive the driving force from the outside of the developing box (such as an imaging device, a force-applying tool used by a user, etc.), and the transmitting body 41b is used to transmit the driving force. Specifically, the transmitting body 41b transmits the driving force to at least one of the developing member driving member 42, the powder feeding member driving member 43 and the stirring member driving member 44. Preferably, the transmitting body 41b is configured as a gear. More preferably, the force-bearing body 41a and the transmitting body 541b are formed integrally.

[0043] 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 1BAs 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 5 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.

[0044] The developer regulating member 29 includes a fixed body 291 fixedly connected to the housing 2 and a regulating body 292 provided on the fixed body 291. The regulating body 292 is used to contact the developing roller 31 / developing layer 312. The fixed body 291 includes a first portion 291a and a second portion 291b. The regulating body 292 is connected to the second portion 291b. The developer regulating member 29 is fixedly connected to the housing 2 via the first portion 291a or the second portion 291b. A bending portion 293 is formed between the first portion 291a and the second portion 291b. Figure 3 As shown, the bending angle of the bending portion 293 (the included angle between the first portion 291a and the second portion 291b) can be any one of an acute angle, a right angle and an obtuse angle.

[0045] Continue as Figure 3 As shown, the developing box 1 also includes a partition 12 arranged in the internal space 100 enclosed by the shell 2, and the partition 12 extends along a first direction. Along a direction intersecting with the first direction (a second direction), the partition 12 divides the internal space 100 into a developing chamber 20 located in front of the partition 12 and a developer chamber 10 located behind the partition 12, wherein the developer chamber 10 is used to accommodate the developer, and the developing part 31 and the powder feeding part 32 are rotatably arranged in the developing chamber 20; specifically, the partition 12 is formed by protruding upward from the lower shell 2b.

[0046] 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.

[0047] 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.

[0048] [Right end cap]

[0049] 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 visible to the user simultaneously, 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.

[0050] [Paper Guide]

[0051] 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.

[0052] In practice, to prevent 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.

[0053] 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.

[0054]

Drive force transmission component

[0055] The driving force transmission component 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43 and a stirring member driving member 44. When a stirring member driving member 44 is provided, the driving force transmission component 4 also 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 set to rotate around an axis parallel to the first direction, or it can be set to reciprocate in a direction roughly 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 set as a gear.

[0056] 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.

[0057]

Detection device

[0058] 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 the developing box only needs to focus on the assembly of the driving end when being assembled.

[0059] [Drive components]

[0060] 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.

[0061] Figure 6 1 is a schematic diagram of a state in which the conductive member of the developing cartridge according to the twelfth embodiment of the present invention is separated from the housing; Figure 7 is a side view of the developing cartridge according to the twelfth embodiment of the present invention observed from right to left along a first direction; Figure 8 It is a schematic diagram of the state in which the left end cover and the chip assembly of the developing box involved in the twelfth embodiment of the present utility model are separated from the shell.

[0062] like Figure 6 As shown, the conductive member 26 in this embodiment includes a main body portion 26a, a power input portion 26b and a vacant portion 26f, wherein the power input portion 26b and the vacant portion 26a1 are both arranged on the main body portion 26a, and the power input portion 26b is used to receive power from the imaging device and supply it to at least one of the developing member 31, the powder feeding member 32 and the developer regulating member 29.

[0063] In some embodiments, the vacant portion 26f is formed between two adjacent portions of the main body 20a, such as Figure 6 As shown, the main body portion 26a has a first adjacent portion 26a1 and a second adjacent portion 26a2, and the vacant portion 26f is located between the first adjacent portion 26a1 and the second adjacent portion 26a2. Figure 7 As shown, when viewed along the first direction, the conductive member 26 does not overlap with the partition 12 . Preferably, when viewed along the first direction, the vacant portion 26 f overlaps with the partition 12 .

[0064] In some embodiments, the first adjacent portion 26a1 and the second adjacent portion 26a2 do not need to be formed in the main body 26a. When observed along the first direction, the conductive member 26 does not overlap with the partition 12. At this time, the partition 12 is located outside the range of the conductive member 26, which is equivalent to a portion of the conductive member 26 being cut off, and the cut-off portion forms a vacant portion 26f. Based on this concept, as long as it is ensured that the conductive member 26 does not overlap with the partition 12 when observed along the first direction, the portion outside the conductive member 26 can be regarded as the vacant portion 26f of the conductive member 26.

[0065] Through such a design, on the one hand, the installation position requirements of the conductive part 26 are reduced, as long as the power input part 26b can receive power from the imaging device and supply power to at least one of the developing part 21, the powder feeding part 32 and the developer regulating part 29 through the power output part 26e; on the other hand, the material used in the conductive part 26 can be reduced, and at the same time, the area occupied by the conductive part 26 is reduced, so that the design freedom of other components in the developing box can be improved.

[0066] As described above, the movable member A94 for accommodating the chip 7 can be set on the left end cover 27 or on the housing 2. This embodiment also provides a movable member A94 that is more convenient for installing the chip 7. The movable member A94 also has an installation port A941 for allowing the chip 7 to be installed and removed. The installation port A941 faces the first direction. Specifically, Figure 8 As shown, when the movable part A94 is set in the shell 2, the installation port A941 faces the left. At this time, the user can install the chip 7 from left to right toward the installation port A941 along the first direction. On the contrary, when the movable part A94 is set in the left end cover 27, the installation port A941 faces the right. At this time, the user can install the chip 7 from right to left toward the installation port A941 along the first direction.

[0067] Regardless of whether the installation port A941 is facing left or right, compared with when the installation port A941 is facing other directions, the developer box 1 with this design is more convenient for the user to install or remove the chip 7. The reason is that the user can operate the chip 7 when the developer box 1 is in a flat posture, without having to place the developer box 1 in a specific posture to operate the chip 7.

[0068] Example 2

[0069] Figure 9 This is a three-dimensional view of the interior of the shell after another type of partition is provided in the developer box involved in the thirteenth embodiment of the present invention.

[0070] In the above embodiment, as a preferred embodiment, the separator 12 is formed integrally with the housing 2. In this case, the separator 12 is formed as a non-deformable three-dimensional component. At the same time, in order to facilitate the smooth flow of the developer from the developer chamber 10 to the developing chamber 20, the separator 12 also has a guide surface 121 facing the developer chamber 10 (such as Figure 3 and Figure 7 (as shown), the guide surface is configured as an inclined surface or an arcuate surface inclined relative to the second direction, which complicates the structure of the housing 2. Unlike the above embodiment, the partition 12 in this embodiment is made of a flexible material. Thus, the partition 12 does not need to be provided with the guide surface 121. Accordingly, the structure of the housing 2 can be simplified, and the volume of the developer chamber 10 can also be increased.

[0071] In one embodiment, the separator 12 is made of a porous material, for example, the separator 12 is made of a sponge. By utilizing the adsorption property of the porous material, even if the separator 12 is not provided with a guide surface, the developer reaching the rear of the separator 12 can be adsorbed by the separator 12 and then supplied to the developing chamber 20.

[0072] Furthermore, the provision of the partition 12 is also beneficial for preventing the developer reaching the developing chamber 20 from flowing back into the developer chamber, so that the developing member 31 can obtain sufficient developer supply.

[0073] Example 3

[0074] Figure 10 This is a side view of the developer box involved in Example 14 of the present utility model, when the left end cover is hidden and viewed from left to right along the first direction.

[0075] As described above, the force-bearing body 41a is used to receive the driving force from outside the developing box, and the transmission body 41b is used to transmit the driving force. Relatively speaking, the vibration amplitude generated by the force-bearing body 41a is larger, especially at the moment when the force-bearing body 41a receives the driving force.

[0076] In the developer regulating member 29, the first portion 291a, the second portion 291b, and the regulating body 292 are generally flat-plate shaped. This allows the first portion 291a, the second portion 291b, and the regulating body 292 to more easily dissipate external forces. Conversely, the bent portion 293 is more susceptible to external forces, causing displacement of the developer regulating member 29. To reduce the impact of vibration generated by the force-bearing body 41a on imaging quality, based on the above embodiment, in the developer cartridge provided in this embodiment, at least the force-bearing body 41a does not overlap with the bent portion 293 when viewed along the first direction. This reduces the impact of vibration generated by the force-bearing body 41a on the bent portion 293, and consequently, reduces the impact of the vibration on the contact between the developer regulating member 29 and the developing member 31.

[0077] Furthermore, when viewed along the first direction, the conveying body 41b does not overlap with the bending portion 293, so that the influence of the vibration generated by the driving force receiving member 41 on the bending portion 293 is further reduced, and the influence of the vibration on the contact between the developer regulating member 29 and the developing member 31 is also further reduced.

[0078] Example 4

[0079] Figure 11 It is a side view of the developing box involved in Example 15 of the present invention observed from right to left along the first direction.

[0080] like Figure 11As shown, based on the fourteenth embodiment, this embodiment further defines that when viewed along the first direction, the conductive member 26 does not overlap with the bent portion 293 .

[0081] As described above, the bent portion 293 is more susceptible to the influence of external forces, causing the developer regulating member 29 to be displaced / vibrated. When the bent portion 293 is displaced / vibrated by external forces, the displacement / vibration amplitude of the bent portion 293 will be the largest relative to the first part 291a, the second part 291b and the regulating body 292. When the technical solution of this embodiment is adopted, the displacement / vibration that may be generated by the developer regulating member 29 / the bent portion 293 will effectively reduce the impact of the contact between the conductive member 26 and the power output member.

[0082] Example 5

[0083] Figure 12 It is a schematic diagram of the relative positions of the conductive part and the developer regulating part in the developing box involved in the sixteenth embodiment of the present utility model.

[0084] Based on the inventive concept of the present utility model, similar to the ninth embodiment, the conductive member 26 in this embodiment is also configured to supply power to the developer regulating member 29, such as Figure 12 As shown, the power output portion 26 e of the conductive member 26 abuts against the developer regulating member 29 , and thus, at least a portion of the developer regulating member 29 overlaps with the conductive member 26 when viewed in the first direction.

[0085] Specifically, the conductive member 26 can abut against both the fixed body 291 and the adjusting body 292; preferably, the conductive member 26 is detachably combined with the right bracket 2g, and more preferably, the conductive member 26 is formed by bending a sheet of conductive material. In this way, the conductive member 26 will have a certain elasticity, and even if observed along the first direction, at least a portion of the developer adjusting member 29 overlaps with the conductive member 26. In the case that the developer adjusting member 29 is displaced / vibrated, the impact on the conductive member 26 will be effectively reduced.

[0086] When the conductive member 26 is formed separately from the right bracket 2g, the layout flexibility of the components in the developer box can be improved. For example, the size, shape, installation position, etc. of the right bracket 2g can be enlarged or reduced according to design requirements, and the size, shape, installation position, etc. of the conductive member 26 can also be changed according to design requirements, as long as the conductive member 26 can receive electricity from the imaging device and supply it to at least one of the developing member 31, the powder feeding member 32 and the developer regulating member 29.

[0087] In some embodiments, the conductive member 26 and the right bracket 2g may be formed integrally. In this case, the number of parts of the developing box may be reduced, and accordingly, the assembly steps of the developing box may be simplified.
