When the processing box 100 is installed in the imaging device 1, the tube control member 4 can be used to control the forward movement of the power receiving member 103 and can correctly guide the processing box 100 to be installed in the imaging device 1.

[0049] [Overall structure of the processing box]

[0050] like Figure 4-10As shown, a processing cartridge 100 in Embodiment 1 of the present invention is shown. As can be known from the foregoing description, the processing cartridge 100 can be detachably installed in the imaging device 1 in the direction from back to front; the processing cartridge 100 includes a housing 101 for accommodating a developer, a developing roller 104 rotatably supported on the housing 101 for carrying the developer, and a photosensitive drum 102 for forming an electrostatic latent image, a power receiving member 103 is connected to the right end of the photosensitive drum 102, and the power receiving member 103 has a pair of claws arranged at an interval of 180 degrees. In other words, the pair of claws are arranged at an angle of 180 degrees to each other. Arranged in this facing manner, the claws of the power receiving member 103 can be matched and meshed with the claws of the power output member 3, and can receive the driving force transmitted by the power output member 3 to rotate, and then, the power receiving member 103 can drive the photosensitive drum 102 and the developing roller 104 to rotate, the photosensitive drum 102 can rotate around the photosensitive drum rotation axis A2 extending in the left and right directions, and the developing roller 104 can rotate around the developing roller rotation axis A1 extending in the left and right directions; the processing box 100 also includes a chip that can establish a communication connection with the imaging device 1, and the chip has an electrical contact surface that can electrically contact the imaging device 1.

[0051] In the processing box 100, the claw of the power receiving member 103 extends from the right end of the processing box 100 and is exposed to the outside. Therefore, in order to avoid the power receiving member 103 from colliding with the outside during transportation and damaging the power receiving member 103, and for positioning the processing box 100, the shell 101 of the processing box 100 also includes a bearing member 110, which is arranged at the right end of the photosensitive drum 102 and arranged adjacent to the power receiving member 103. The bearing member 110 includes a main body 111 constructed in a plate shape, and a substantially circular through hole 112 (avoidance hole) is formed on the main body 111. At least a portion of the power receiving member 103 is exposed to the outside of the processing box 100 through the through hole 112. The bearing member 110 also includes a positioned portion for positioning the bearing member 110 on the housing 101. Specifically, the positioned portion includes a first positioned portion 116, a second positioned portion 117 and a third positioned portion 118, wherein the first positioned portion 116 is arranged above the rotation axis of the power receiving member 103 in the up-down direction, and the first positioned portion 116 is configured as a groove formed on the main body 111 facing the side of the photosensitive drum 102. Preferably, the groove is an arc-shaped groove arranged around the power receiving member 103, corresponding to the first positioning portion 101a configured as an arc-shaped rib provided on the housing 101, and the bearing member 110 is clamped on the first positioning portion 116 of the housing 101. 01a, and can position the bearing component 110 in a radial direction perpendicular to the left and right directions, and can also play a role in pre-positioning the bearing component 110 when the bearing component 110 is installed on the housing 101. Optionally, the first positioned portion 116 can be constructed as a rib structure, and the first positioning portion 101a can be constructed as a groove structure, which can also position the bearing component 110; the second positioned portion 117 is constructed as a hole formed on the main body 111, and corresponds to the second positioning portion 101b constructed as an axis formed on the housing 101. The two can position the bearing component through the hole-axis cooperation. Preferably, the second positioned portion 117 is a waist-shaped hole, which helps to avoid the bearing The positioning interference caused by the manufacturing error of the component 110 improves the installation error tolerance of the bearing component 110. Optionally, the second positioned portion 117 can be configured as an axis, and the second positioning portion 101b can be configured as a hole, which can also position the bearing component; the third positioned portion 118 is configured as a hole formed on the main body 111, corresponding to the hole also formed on the housing 101, and the bearing component 110 can be fixed to the housing 101 by connecting members such as screws. Therefore, the bearing component 110 can be stably positioned by providing the first positioned portion 116, the second positioned portion 117 and the third positioned portion 118, and cooperating with the positioning portion provided on the housing 101;A protrusion extending to the right from the main body 111 is also provided on the main body 111, and the protrusion is arranged around the through hole 112. Specifically, the protrusion includes a first protrusion 113 and a second protrusion 114, which are respectively arranged on the upper and lower sides of the through hole 112, and a first end 113a is provided at the front end of the first protrusion 113, and a second end 114a is provided at the front end of the second protrusion 114, and the first end and the second end are spaced apart in the up and down directions; further, in the left and right directions, at least a part of the protrusion is located at the right end of the power receiving member 103. In other words, the protrusion is at least arranged to protrude more to the right than the power receiving member 103. This structure allows the first protrusion 113 and the second protrusion 114 of the bearing member 110, which protrude more to the right, to collide with the outside before the power receiving member 103 collides with the outside when the processing box 100 inevitably collides with the outside. The first protrusion 113 and the second protrusion 114 of the bearing member 110 can be used as an anti-collision structure to protect the power receiving member 103 from damage. Moreover, when the process cartridge 100 is installed in the imaging device 1, the second protrusion 114 can be supported on the support portion 5 of the imaging device 1 located below it as a supported portion. In the up-down direction, the support portion 5 is arranged on the lower side of the rotation axis of the power output member 3. The first protrusion 113 can be elastically pushed by the elastic pushing member 6 arranged thereon and located in the imaging device 1, and a pushing force toward the second protrusion 114 is applied. The state in which the second protrusion 114 is supported on the support portion 5 will be stably maintained, so that the process cartridge 100 can be stably positioned in the imaging device 1. ;

[0052] Furthermore, a relief portion 115 connected to the through hole 112 is provided on the main body portion 111, and the relief portion 115 does not extend in the direction of the rotation axis A2 of the photosensitive drum (the rotation axis A2 is also the rotation axis of the power receiving member 103). Preferably, the relief portion 115 is constructed as an opening provided between the first protrusion 113 and the second protrusion 114. When viewed in a direction perpendicular to the left and right directions, the rotation axis A1 of the developing roller 104, the rotation axis A2 of the photosensitive drum 102 and the relief portion 115 are arranged in sequence. When the processing cartridge 100 is installed in or removed from the imaging device 1, the relief portion 115 can be used to avoid the imaging device 1. The avoidance portion 115 is defined by a plane 115a on the right side of the main body 111 and a space on the right side of the plane 115a. The plane 115a extends continuously in a direction intersecting the left-right direction and connects the first end and the second end of the protrusion. Compared with the prior art, this significantly increases the size of the avoidance portion 115, and can avoid interference with the tube control 4 to the greatest extent. Preferably, the plane 115a extends continuously in a direction perpendicular to the left-right direction, so that the plane 115a is roughly parallel to the right end face of the tube control 4, which can further avoid the tube control 4 of the imaging device 1.

[0053] Further, such as Figure 8 As shown, another structure of the bearing component 110 in Example 1 of the utility model is shown. In this scheme, the plane 115a is arranged around the power receiving member 103, and the part of the bearing component 110 that is adjacent to the first protrusion 113 and located on the upper side of the first protrusion 113 and the part that is adjacent to the second protrusion 114 and located on the lower side of the second protrusion 114 are both planes, which are part of the plane 115a, and there is no protrusion protruding to the right from the plane 115a. Compared with the above scheme, the plane 115a has a larger range, which can further avoid the possibility of interference with the components in the imaging device 1.

[0054] Example 2

[0055] like Figure 11-15As shown, a processing box 200 in Example 2 of the utility model is shown. The parts of the processing box 200 that are the same as those in the above-mentioned Example 1 are not repeated here. The difference is that the lower side of the first protrusion 113 of the processing box 200 is not provided with a supported portion (second protrusion) protruding to the right from the plane 215a for supporting in the imaging device 1, that is, on the bearing member 210, the part of the first protrusion 213 facing the lower side of the processing box 200 is constructed as a plane 215a intersecting with the left and right directions, and the plane 215a will be further continuously extended compared with the plane in the embodiment. In this way, the avoidance portion 215 will have a larger avoidance range than the avoidance portion in Example 1, further avoiding the possibility of interference with the tube control 4, and the installation of the processing box 200 will be smoother, and the installation / disassembly fault tolerance rate is greatly improved. That is to say, because the second protrusion is no longer provided in the processing box 200, the position of the right end of the processing box 200 for supporting the processing box 200 is changed.

[0056] Next, the new supporting structure of the processing box 200 will be described in detail. A restricted portion 231 and a first supported portion 232 are arranged at intervals in the front-to-back direction at the right end of the shell 201 of the processing box 200. That is, in the installation direction of the processing box 200, the restricted portion 231 is arranged on the downstream side of the first supported portion 232, and in the installation direction of the processing box 200, the power receiving member 203 is arranged between the restricted portion 231 and the first supported portion 232, that is, the first supported portion 232, the restricted portion 231, and the power receiving member 203 are arranged in sequence, and in the up-down direction, the restricted portion 231 and the first supported portion 232 are arranged on the upper side of the first protrusion 231; further, the restricted portion 231 and the first supported portion 232 are both constructed as protrusions protruding outward from the right end surface of the shell 201, that is, the restricted portion 2 31 is a restricted protrusion, and the first supported portion 232 is a supported protrusion. In the process of installing the processing box 200 to the imaging device 1, the processing box 200 can be installed in the imaging device 1 along a predetermined installation direction under the guidance of the second rail 2b through the restricted portion 231 and the first supported portion 232. The restricted portion 231 located at the front side of the power receiving member 203 in the front-to-back direction will abut against the restricting portion 7 formed at the upper end of the second rail 2b, and the restricting portion 7 is a surface arranged on the upper side of the second rail 2b, thereby suppressing the tendency of the processing box 200 to move upward. The first supported portion 232 located at the rear side of the power receiving member 203 in the front-to-back direction can be supported on the first supporting portion 8 formed on the lower side of the second rail 2, and the first supporting portion 8 is a groove structure arranged on the lower side of the second rail 2b, thereby suppressing the tendency of the processing box 200 to move downward.Furthermore, it can be known from Example 1 that when the processing box 200 is installed in the imaging device 1, the first protrusion 213 will be elastically pushed downward by the elastic pushing member 6 in the imaging device 1, the restricted portion 231 of the processing box 200 abuts against the restricting portion 7, and the first supported portion 232 is supported on the first supporting portion 8. This arrangement state will be maintained before the processing box 200 performs a printing operation. When the processing box 200 performs a printing operation, the power receiving member 203 itself can receive a rotational force that rotates in a counterclockwise direction when viewed from right to left, and the rotational torque generated by it has a tendency to force the processing box 200 to swing counterclockwise, which will cause the restricted portion 231 and the first supported portion 232 to swing counterclockwise, which will cause the restricted portion 231 and the first supported portion 232 to swing counterclockwise. They can be tightly attached to the limiting portion 7 and the first supporting portion 8 of the imaging device 1, respectively. The limited portion 231 of the process cartridge 200 abuts against the limiting portion 7 and the first supported portion 232 is supported on the first supporting portion 8. This arrangement state can also be maintained when the process cartridge 200 performs printing work, which can effectively avoid the possibility of the process cartridge 200 swinging due to the rotating member (such as the power receiving member 203) being subjected to a rotating torque during operation. That is, by providing the limited portion 231 and the first supported portion 232, the swing of the process cartridge 200 during operation can be effectively suppressed, and the process cartridge 200 can be stably positioned in the imaging device 1. ;

[0057] Furthermore, a second supported portion 233 is also provided on the shell 201 for supporting the processing box 200. Specifically, the second supported portion 233 is arranged at the bottom of the shell 201, and is arranged at a position closer to the left side of the shell 201 in the left-right direction relative to the first supporting portion 232. This allows the processing box 200 to be supported not only at the right end, but also to be auxiliary supported by the second supported portion 233. In this way, the processing box 200 can be positioned in the imaging device 1 in a more balanced and stable posture.

[0058] Furthermore, the processing box 200 also includes a first positioned portion 216 arranged on the bearing member 210 and a second positioned portion 217 arranged on the shell 201. In the installation direction of the processing box 200, the first positioned portion 216 and the second positioned portion 217 are both arranged on the downstream side of the power receiving member 203, but at least a part of the second positioned portion 217 is closer to the front side of the processing box 200 than the first positioned portion 216, that is, in the installation direction of the processing box 200, at least a part of the second positioned portion 217 is arranged on the downstream side of the first positioned portion 216, and in the left-right direction, the first positioned portion 216 is arranged on the right side of the second positioned portion 217; wherein, the first positioned portion 216 is arranged on the right side of the second positioned portion 217. The positioning portion 216 is located at the front end of the bearing member 210. The first positioned portion 216 is configured as a surface disposed at the front end of the bearing member 210. Preferably, the surface is an arc surface. During the installation of the process cartridge 200, the first positioned portion 216 can abut against the first positioning portion 11 of the imaging device to limit the process cartridge 200 from moving forward. In other words, the first positioned portion 216 can be used to limit the movement of the process cartridge 200 in the installation direction; and the second positioned portion 217 is configured as a protrusion protruding outward from the front side of the housing 201, which can be used to limit the movement of the process cartridge 200 in the left-right direction in the imaging device 1, so as to accurately position the process cartridge 200 in the left-right direction in the imaging device 1. Optionally, the first positioned portion 216 can also be disposed on the housing 201, and the second positioned portion 217 can also be disposed on the bearing member 210, which is not limited.

[0059] Alternatively, as another optional embodiment, the restricted portion 231 and the first supported portion 232 in this embodiment can not only be separately and spaced apart from each other as protrusions at the right end of the shell 201, but can also be two parts respectively formed on the rib, and the rib is constructed to extend in the installation direction of the processing box 200 and have an overlapping portion with the power receiving part 203 in the installation direction of the processing box 200, that is, the rib is arranged to be long enough to stably position the processing box 200, and therefore, the structure of the restricted portion 231 and the first supported portion 232 is not limited.

[0060] Example 3

[0061] like Figure 16-20 As shown, a processing box 300 in embodiment 3 of the utility model is shown. The same parts of the processing box 300 as those in the above embodiments are not described here. The difference is that the supporting structure of the processing box 300 is changed.

[0062] Specifically, the lower side of the first protrusion 113 on the bearing member 310 is also not provided with a supported portion protruding to the right from the plane 315a for supporting in the imaging device 1, that is, on the bearing member 310, the portion of the first protrusion 313 facing the lower side of the processing box 200 is also constructed as a plane 315a that intersects with the left and right directions. Compared with Example 1, this increases the extension range of the plane 315a, and can further avoid the possibility of interference with the tube control 4 or other components in the imaging device 1. The installation of the processing box 300 will be smoother, and the installation / disassembly fault tolerance will be greatly improved. Therefore, the processing box 300 also includes a third supported portion 334 arranged on the bearing member 310, and the third supported portion 334 is arranged on the lower side of the first protrusion 313 in the up-down direction. Furthermore, the third supported portion 334 is arranged at the lower end of the bearing member 310 in the up-down direction, and is constructed as a protrusion protruding downward from the lower end of the main body 311 of the bearing member 310. In the left-right direction, the third supported portion 334 is spaced apart from the first protrusion 313. More specifically, in the left-right direction, the third supported portion 334 is arranged on the left side of the first protrusion 313; the imaging device 1 also includes a third supporting portion 12 spaced apart from the first supporting portion 5 in the left-right direction, and the third supporting portion 12 is arranged on the first supporting portion in the left-right direction. 5 is on the left side, and the third supporting portion 12 is arranged on the lower side of the first supporting portion 5 in the up-down direction. When the processing box 300 is installed in the imaging device 1, the third supported portion 334 can abut against the third supporting portion 12 in the imaging device 1, so that the right side of the processing box 300 is supported, and it can be known from the previous description that the first protrusion 313 can be elastically urged downward (i.e., in the up-down direction toward the third supported portion 334) by the elastic pushing member 6, so that the third supported portion 334 can maintain a stable abutment with the third supporting portion 12 in the imaging device 1 to position the box; further, the third supported portion 334 is integrally formed with the bearing member 310, which helps to reduce the number of molds in a set when producing the two, thereby reducing production costs.

[0063] It is worth mentioning that a second supported portion 333 having substantially the same structure and position as that in Embodiment 1 may also be provided in this embodiment. The second supported portion 333 is disposed on the bottom surface of the lower end of the shell 301, and is disposed at a position closer to the left side of the processing box 300 in the left-right direction than the third supported portion 334, which will not be elaborated here.

[0064] Example 4

[0065] like Figure 21-23 As shown, a processing box 400 in embodiment 4 of the utility model is shown. The same parts of the processing box 400 as those in the above embodiments are not repeated here. The difference is that the structure of the bearing component 410 of the processing box 400 has changed.

[0066] Specifically, the bearing member 410 of the processing box 400 is further provided with a surface 419 (second surface), which is provided between the extended end of the first protrusion 413 and the plane 415a (first surface) in the left-right direction, that is, the surface 419 is farther away from the left end of the processing box 400 in the left-right direction relative to the plane 415a; on the front side of the bearing member 410, a joint surface 420 is connected between the surface 419 and the plane 415a, and the surface 419, the joint surface 420, and the plane 415a are jointly constructed into a stepped structure; In a direction perpendicular to the right direction, a first virtual line L1 is drawn connecting the developing roller rotation axis A1 and the photosensitive drum rotation axis A2, and a second virtual line L2 is drawn passing through the photosensitive drum rotation axis A2 and perpendicular to the first virtual line L1, the second virtual line L2 has a first side and a second side relative to each other, the developing roller rotation axis A1 is located on the second side of the second virtual line L2, and in a direction intersecting the left and right directions, the plane 415a extends continuously from the first side of the second virtual line L2 to the second side of the second virtual line L2, and no protrusion structure is provided on the plane 415a.

[0067] Further, the first virtual line L1 has a third side and a fourth side opposite to each other, and the plane 415 a is configured to extend from the third side of the first virtual line L1 to the fourth side of the first virtual line L1 .

[0068] Furthermore, a third virtual line L3 is made passing through the rotation axis A2 of the photosensitive drum 402 and the front side of the engaging surface 420, with the third virtual line L3 being used as a dividing line. The third virtual line L3 has a first side and a second side. The upper end of the first protrusion 413 is arranged on the fifth side of the third virtual line L3, and the sixth side is opposite to the fifth side. The right end portion of the bearing member 410 on the second side of the third virtual line L3 is constructed as a plane 415a, and no protrusion protruding outward from the plane 415a is arranged on the plane 415a. That is to say, the range of the avoidance portion 415 will be further increased. Compared with the aforementioned embodiment, this further avoids the possibility of interference with the tube control 4, the installation of the processing box 400 will be smoother, and the installation / disassembly fault tolerance will be greatly improved.

[0069] It is worth mentioning that the support structure of the processing box 400 in this embodiment can be applicable to the support structure of the processing box in Example 2 or Example 3, which can be combined with the structure of the bearing component 410 in this embodiment, and will not be repeated here.

[0070] Example 5

[0071] like Figure 24-25As shown, a processing box 500 in embodiment 5 of the utility model is shown. The same parts of the processing box 500 as those in the above-mentioned embodiment are not repeated here. The difference is that the power receiving member 503 in this embodiment is movable relative to the housing 501. Specifically, the power receiving member 503 can move in a direction intersecting the left and right directions. That is, the rotation axis A2 of the power receiving member 503 can be offset relative to the rotation axis of the photosensitive drum 502. Correspondingly, the bearing member 510 is also provided with left and right through the bearing member 510. The avoidance grooves 521 on both sides are arranged at the rear side of the through hole 512 and remain connected with the through hole 512 to allow the power receiving member 503 to slide in the avoidance grooves 521 to avoid interference with the bearing member 510. Therefore, the power receiving member 503 has a first position and a second position. When the power receiving member 503 is in the first position, its rotation axis is coaxial with the rotation axis of the photosensitive drum 502. When the power receiving member 503 is in the second position, its rotation axis is not coaxial with the rotation axis of the photosensitive drum 502 and is arranged at the rear side of the rotation axis of the photosensitive drum 502.

[0072] Furthermore, the processing box 500 also includes an elastic member 522 arranged on the right side of the shell 501. Preferably, the elastic member 522 is a torsion spring, one end of which abuts on the power receiving member 503, and the other end abuts on a protrusion formed on the bearing member 510. The elastic force generated by the elastic member 522 can be applied to the power receiving member 503 to keep the power receiving member 503 in the first position when the power receiving member 503 is not subjected to external force, and can reset the power receiving member 503 in the second position to the first position.

[0073] During the process of installing the processing box 500 to the imaging device 1, when the power receiving member 503 interferes with the power output member 3 of the imaging device 1 in the installation direction of the processing box 500, the power receiving member 503 can be blocked by the power output member 3 and can move backward in the avoidance groove 521 after overcoming the elastic force of the elastic member 522 to avoid the power output member 3, thereby avoiding the problem that the processing box 500 cannot be installed in place due to the interference between the two, resulting in the door cover of the imaging device 1 cannot be closed normally. When the processing box 500 is installed to the position where the rotation axis of the photosensitive drum 502 and the rotation axis of the power output member 3 are coaxial, the installation process of the processing box 500 is completed. At this time, the rotation axis A2 of the power receiving member 503 is not coaxial with the rotation axis of the power output member 3. After the imaging device 1 is started, the power output member 3 starts to rotate. As the power output member 3 rotates, the power output member 3 can complete the engagement with the power receiving member 503 during the rotation process. At this time, the power receiving member 503 can be pushed by the elastic member 522 and return to the first position from the second position again.

[0074] It is worth mentioning that the support structure of the processing box 500 in this embodiment can be applicable to the support structure of the processing box in Example 2 or Example 3, which can be combined with the structure of the bearing component 510 in this embodiment, and other structures of the bearing component 510 in Example 4 can also be suitable for the bearing component in this embodiment. The two can be combined with each other, which will not be repeated here.

Beneficial Effects

[0076] The processing box in the utility model is provided with a bearing component, which can, on the one hand, prevent the power receiving part from colliding with the outside and being damaged during the transportation of the processing box; on the other hand, by providing an avoidance portion on the bearing component, it can prevent the processing box from interfering with the tube control component of the imaging device during the installation / disassembly process. Moreover, under the premise of ensuring that the processing box can be stably supported in the imaging device, the avoidance portion is constructed as a range limited by the plane on the bearing component and the space at the right end of the plane, which can avoid interference with the tube control component to the greatest extent. The installation of the processing box will be smoother, and the installation / disassembly fault tolerance rate will be greatly improved.
