Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printing equipment, and particularly relates to a container for storing powder and a toner cartridge. BACKGROUND

[0002] The toner cartridge is an important component in a laser printing device, and is internally provided with a developer. When the developer is used up, the toner cartridge needs to be replaced. The toner cartridge is provided with important structures for imaging, such as a developing roller and a photosensitive drum. The surface of the photosensitive drum is provided with a photosensitive material. The charge carried by the photosensitive material forms an electrostatic latent image under the action of laser scanning. The developing roller transfers the developer to the photosensitive drum, and then forms an image.

[0003] The printing device body is provided with a driving structure. When the toner cartridge is assembled in the device, the driving structure is engaged with a transmission structure on the toner cartridge to transmit power to the developing roller and the photosensitive drum. In some prior art, the photosensitive drum and the developing roller are usually driven by different driving components, so as to avoid the problem of too long transmission chain caused by providing a single transmission chain on the toner cartridge.

[0004] In the prior art, the developing roller, the powder feeding roller and the stirring frame are all arranged on a transmission chain. The transmission chain is prone to be too long. In addition, the stirring frame is located on the side farthest from the photosensitive drum compared with the developing roller and the powder feeding roller. Therefore, the stirring frame is usually located at the end of the transmission chain. In addition, the stirring frame will generate a large resistance to the transmission chain during the stirring and mixing process, which will affect the running stability of other components, especially the connecting structure of the developing roller. The connecting structure of the developing roller is provided with a buffer sealing pad to adapt to the pre-tightening of the photosensitive drum. The stirring frame will affect the stable rotation due to the continuous contact with the developer in the pushing cavity. The load will have a corresponding floating, thereby affecting the running stability of the entire transmission chain. SUMMARY

[0005] In order to overcome the defects of the prior art, the purpose of the present application is to provide a container for storing powder and a toner cartridge, which can overcome the problem that the stirring frame running easily affects the stable rotation of the remaining components, and make the imaging process more smooth.

[0006] The present invention provides, in a first aspect, a container for storing powdered material, comprising: a shell having a developer storage chamber therein; a developing roller disposed on the shell and rotatable about a first axis for transferring developer from the developer storage chamber to the outside of the shell; a power transmission assembly including a first power receiving portion and a transmission portion linked to the first power receiving portion, the first power receiving portion having a connecting portion capable of receiving a first power, the transmission portion forming a power transmission path that transmits the first power away from a rotating component as the first power receiving portion moves, the first power originating from the rotating component having a photosensitive material surface; and a stirring component including: a connecting portion connected to the shell and movable relative to the shell; a stirring portion disposed within the developer storage chamber, linked to the connecting portion and capable of performing a first movement as the connecting portion moves; and a second power receiving portion located on the power transmission path of the transmission portion, including a driving portion for receiving driving force from the power transmission path and a transmission portion for transmitting driving force to the connecting portion.

[0007] According to the container provided in the first aspect of the present invention, a power transmission assembly is provided to receive power from a rotating component (photosensitive drum) to transmit the power of the rotating component to the stirring frame. This avoids the transmission stability of the entire transmission structure being affected by an excessively long transmission chain, including the developing roller, within the container, thus improving the controllability of timing control during imaging. At the same time, since the photosensitive drum does not directly contact the developer in the cavity, its transmission chain is shorter than that of the developing roller, resulting in good rotational stability. Therefore, by connecting the stirring component to the power transmission assembly via a second power receiving component, the stirring component can be effectively excluded from the transmission chain of the developing roller and incorporated into the photosensitive drum. This ensures the transmission stability of the stirring component without affecting the smooth transmission of the photosensitive drum and the developing roller, making the overall timing of the imaging process more controllable.

[0046] The technical solutions of the present application will be described in detail below with reference to the drawings and specific examples.

[0047] The embodiments of the present application provide an electronic imaging device, referring to Figure 1 , including a device body 1 and a paper box 11, a pickup assembly 12, a conveying assembly 13, a transfer assembly 14, a developing assembly 15, a scanning assembly 16, a fixing assembly 17 and a paper discharge assembly 18 arranged in the device body 1, the device body 1 is provided with a paper conveying path, the paper box 11 is stacked and stored with paper for printing, the pickup assembly 12 includes a pickup roller, the pickup roller is in contact with the stacked paper and sends the paper into the paper conveying path, the conveying assembly 13 includes a correction roller and a paper feed roller, the correction roller is used to correct the position of the paper in the paper conveying path, and the paper feed roller is used to transmit the paper in the paper conveying path, the developing assembly 15 forms an image composed of toner inside and transfers the image to the transfer assembly 14, the transfer assembly 14 transfers the image in the paper conveying path, the paper is further conveyed to the fixing assembly 17 after obtaining the image, the fixing assembly 17 fixes the image on the surface of the paper by heating, and the paper after printing is finally discharged to the outside of the device body 1 by the paper discharge assembly 18.

[0048] The scanning assembly 16 includes a laser emitting unit and an optical member for deflecting the laser emitted by the laser emitting unit, and the developing assembly 15 includes a selenium drum, the optical member can be composed of multiple optical components, and the laser is deflected to the selenium drum for the imaging process of the selenium drum. Referring to Figure 3 , the selenium drum includes a rotating part 100 having a photosensitive material surface, which has a photosensitive surface containing a photosensitive surface, and the laser is deflected to the photosensitive surface to form a latent electrostatic image, and the toner forms an image by using the latent electrostatic image.

[0049] Referring toFigures 2 to 16 The toner cartridge includes a container for storing powder and a photosensitive component that mates with the container. In this embodiment, the powder is a developer in granular form. A rotating component 100 is rotatably mounted on the photosensitive component and can rotate about a second axis extending in a first direction. The container includes a housing 200, a developing roller 300, and a stirring component 500. The housing 200 has a developer storage chamber 210 inside and a developer outlet 220 communicating with the developer storage chamber outside. The developing roller 300 is located at the developer outlet 220 of the housing 200 and can rotate along a first axis extending in the first direction. When the photosensitive component mates with the container, the photosensitive surface of the rotating component 100 contacts the surface of the developing roller 300 at a position that is relatively parallel to each other in the first direction, so that the developing roller 300 transfers the developer in the developer storage chamber 210 to the rotating component 100.

[0050] The container also includes a powder feeding roller 600, and a developer delivery channel is provided between the developer outlet 220 and the developer storage chamber 210. The powder feeding roller 600 is disposed in the developer delivery channel and is used to deliver the developer in the developer delivery channel to the developing roller 300, and can rotate along a first direction (e.g., Figure 5 and Figure 7 Rotate along the third axis extending in the direction U. (Continue reading...) Figure 3 The container also includes a coupling component 400, which includes a coupling 410 and a transmission member pulsatingly connected to the coupling 410. In this embodiment, the transmission member is configured as a transmission gear set, which includes a first gear 420 connected to the developing roller 300 and a second gear 430 connected to the powder feeding roller 600. The coupling 410 meshes with the transmission gear set to transmit power to the first gear 420 and the second gear 430. Figure 3 In the illustrated embodiment, the coupling 410 is configured as a coupling gear. The coupling gear, along with the first gear 420 and the second gear 430, are all helical gear structures, having axially arranged first and second coupling tooth portions. The first and second coupling tooth portions mesh with the first gear 420 and the second gear 430 respectively, thereby directly transmitting the driving force to the first gear 420 and the second gear 430 upon receiving external driving force. Specifically, in this embodiment, the coupling gear has a coupling portion 411 at the end away from the housing 200. The coupling portion 411 includes a coupling spacer. The access end of the drive component within the device body extends into the coupling spacer to drive the coupling gear to rotate, thereby driving the developing roller 300 and the powder feeding roller 600.

[0051] Further, the container of the embodiment of the present application further comprises a power transmission assembly 700, the power transmission assembly 700 comprises a first power receiving part 710 and a transmission part 720 coupled with the first power receiving part 710, the first power receiving part 710 has an engaging part 711a capable of receiving the first power, the transmission part 720 forms a power transmission path transmitting the first power in a direction away from the rotating part 100 with the movement of the first power receiving part 710. The first power is from the rotating part 100 having a photosensitive material surface, the transmission part 720 can be provided as a gear set, a belt drive, a synchronous belt drive and the like transmission structure, all within the implementation range, the receiving part can drive the first power receiving part 710 to perform the first movement in a contact manner due to the rotation of the rotating part 100, or can drive the first power receiving part 710 to perform the first movement in a non-contact manner due to the rotation of the rotating part 100, the contact manner can be a gear part, or a friction drive and the like transmission manner. Wherein, the first movement can be implemented as a rotational movement, a linear movement or other curve movement along a preset trajectory.

[0052] Specifically refer to Figure 2 , the photosensitive member comprises a frame 900, when the selenium drum of the embodiment is provided as a split structure, the frame 900 comprises a main shell 910 and a support member 920 connected to the main shell 910, the rotating part 100 is rotationally arranged on the main shell 910, the support member 920 is used to mount the container, and has a container mounting clamping position 921 and a fixing member arranged on the container mounting clamping position 921, the container is detachably connected to the container mounting clamping position 921 and fixed on the container mounting clamping position 921 by the fixing member, the fixing member comprises a positioning part 922, a buckle 923 and an elastic member 924 in the embodiment, the elastic member 924 is arranged on the side of the support member 920 away from the main shell 910, and pushes the container to approach the main shell 910 along a second direction (such as Figure 3 、 Figure 14 and Figure 15 direction V), and provides a pre-tightening force to make the developing roller 300 abut against the rotating part 100, so as to realize the conveying of the developer by the developing roller 300, wherein the second direction is perpendicular to the first direction, the buckle 923 is used to fix the part of the shell 200 in combination with the positioning part 922, so that the shell 200 cannot be separated from the container mounting clamping position 921, and the container is relatively fixed on the support member 920. Wherein, the rotating part 100 is provided with a driving structure, the driving structure is arranged at the end of the rotating part 100 and is implemented as a rotating gear in the embodiment, and after the photosensitive member is assembled in the device body, the rotating gear directly engages with the driving gear on the device body, so as to realize the driving of the rotating part 100. Thus, the rotating part 100 can be directly driven by the driving part in the device body, and the load of the developing roller 300 and the supply roller and the like driven by the coupling part 400 on the container is relatively small.

[0053] Continuing to refer to Figures 10 to 14 The stirring member 500 comprises a connecting portion 510, a stirring portion 520 and a second power receiving portion 530. The connecting portion 510 is engaged with the housing 200 and penetrates from inside the housing 200 to outside the housing 200, so that the stirring portion 520 can receive driving force from outside the developer storage cavity 210. The stirring portion 520 is arranged in the developer storage cavity 210 and can be connected with the connecting portion 510 to perform a first movement with the movement of the connecting portion 510, which can stir the developer in the developer storage cavity 210 and push the developer towards the powder conveying channel 230. The second power receiving portion 530 is used to move the connecting portion 510 relative to the housing 200 to transmit the driving force to the stirring portion 520. The second power receiving portion 530 of the embodiment of the present application is located on the power transmission path of the transmission portion 720 and comprises a driving portion receiving driving force from the power transmission path and a transmission portion transmitting the driving force to the connecting portion 510. The driving portion is engaged with the rotating member 100 when the container is matched with the photosensitive member and can move due to the rotation of the rotating member 100.

[0054] Therefore, the transmission chain of the stirring member 500 is that the first power receiving portion 710 of the power transmission assembly 700 obtains power from the rotating member 100 and directly transmits the power to the second power receiving portion 530 of the stirring member 500 through the transmission portion. The second power receiving portion 530 further transmits the power from outside the housing 200 to the stirring portion 520 in the developer storage cavity 210 in a manner that the connecting portion 712a moves relative to the housing 200, so as to drive the stirring portion 520 to perform the first movement and obtain the stirring effect. Thus, the stirring portion 520 is driven by the rotating member 100 to be separated from the transmission chain of the coupling member 400, which can effectively shorten the length of the transmission chain and balance the lengths of the two transmission chains of the developing roller 300 and the rotating member 100 on the selenium drum. The transmission stability of the stirring member 500 to the developing roller 300 and the powder conveying roller 600 and other structures can be reduced, the first movement of the stirring portion 520 driven by the driving force from the selenium drum can be more stable, and the uniform stirring and transmission of the developer in the developer storage cavity 210 can be realized.

[0055] In one embodiment, the first power receiving portion 710 includes a first member 711 (i.e., the driving portion mentioned in the foregoing embodiment) coupled with the rotating member 100 for receiving the rotating force from the drum, and a second member 712 (i.e., the transferring portion mentioned in the foregoing embodiment) coupled with the transmission portion 720 for transferring the driving force received by the engaging portion 711a to the second member 712 to perform the second motion. The second motion can be a rotating motion, a linear motion, or other curve motion performed in conjunction with the rotating member 100, for example, in this embodiment, the third motion is set to rotate around the fourth axis extending in the first direction, so that the fourth axis is parallel to the second axis to keep the distance between the first member 711 and the rotating member 100 consistent, effectively receiving the driving force from the rotating member 100 and transferring the driving force from the second member 712 to the transmission portion 720.

[0056] In this embodiment, the first member 711 and the second member 712 are coaxially arranged and can rotate around the fourth axis, wherein the engaging portion 711a is arranged at the radially farthest end of the first member 711 and contacts the surface of the rotating member 100, and the contact surface is arranged at the end of the rotating member 100 and is offset from the imaging area of the photosensitive surface of the rotating member 100, so as not to affect the imaging process of the drum, so that the first member 711 is always in contact with the rotating member 100 during rotation around the fourth axis to continuously receive the rotating force of the rotating member 100 to rotate around the fourth axis, so that the second member 712 also rotates around the fourth axis.

[0057] Specifically, referring to Figure 3 and Figure 9 , the fourth axis coincides with the first axis, and the developing roller 300 has a roller end 310 rotatingly arranged on the housing 200 and extending in the first direction, and the first power receiving portion 710 is arranged on the roller end 310 and can rotate relative to the roller end 310. In this structure, the first member 711 and the second member 712 can rotate around the first axis, and the distance between the rotating axes of the two members and the surface of the rotating member 100 is consistent with the distance between the first axis of the developing roller 300 and the surface of the rotating member 100, wherein referring to Figure 2The elastic member 924 provides elastic force in the second direction to make the surface of the developing roller 300 elastically press against the photosensitive surface of the rotating member 100, so that the first member 711 generates the same pressing effect as the developing roller 300 on the rotating member 100. When the container is mounted on the support member 920, the engaging portion 711a always keeps engagement with the surface of the rotating member 100, and the stable transmission of power is achieved.

[0058] The engaging portion 711a is a friction surface in contact with the surface of the drum. When the container is engaged with the photosensitive member, the friction surface is pressed against the surface position of the rotating member 100. When the rotating member 100 rotates, the friction surface drives the first member 711 to move by the friction force generated by the pressing of the rotating member 100, and further drives the second member 712 to perform the third movement. The transmission of driving force by the friction surface can achieve power transmission without corresponding structural changes to the outer surface of the rotating member 100, thereby reducing production costs. When the container is replaced and reassembled on the photosensitive member, there is no problem of assembly calibration difficulty caused by the structure of gear engagement, and the independent replacement of the container in the split structure is facilitated. In combination with the mounting structure of the container on the photosensitive member, when the elastic member 924 provides elastic force in the second direction to make the container close to the main shell 910, the engaging portion 711a will also be pressed against the corresponding outer surface of the rotating member 100 due to the elastic force. Since the first member 711 is arranged at the roller end 310 position, the contact position of the engaging portion 711a is located at the end of the rotating member 100, and no interference conflict with the imaging surface of the rotating member 100 is generated. Therefore, not only the imaging stability of the rotating member 100 is ensured, but also the transmission of driving force in the power transmission assembly 700 is achieved.

[0059] Further, the first member 711 is made of elastic material, and when the first member 711 is made of elastic material, it can be elastically deformed when receiving the pressing force. For example, in the above embodiment, when the engaging portion 711a is a friction surface, the force of the elastic member 924 causes the first member 711 to be pressed against the surface of the rotating member 100, and the first member 711 is deformed relative to the rotating member 100. The deformation increases the contact area of the first member 711 on the rotating member 100, and further increases the friction between the two. Thus, the stable transmission of power between the rotating member 100 and the first member 711 can be effectively ensured. It should be noted that when the first member 711 is coaxial with the developing roller 300, the first diameter of the first member 711 relative to the axis is greater than the second diameter of the transmission surface of the developing roller 300 relative to the axis, so that the first member 711 has a protruding portion relative to the developing roller 300 in the undeformed state. The protruding portion is deformed to increase the contact area when it is pressed against the surface of the rotating member 100. This structure can enable the first power receiving portion 710 to stably receive the driving force from the rotating member 100, and can also reduce the occupied space of the power transmission assembly 700 at the end of the container, so that the overall design size of the container is smaller. It should be noted that the elastic material can be rubber or other elastic materials, which are within the implementation range.

[0060] In addition, the first member 711 and the second member 712 can be arranged as the same part on the rotating member 100. When the part engages the outer surface of the rotating member 100, it serves as the first member 711 for receiving the driving force from the rotating member 100, and when the part is away from the surface of the rotating member 100, it serves as the second member 712 as the driving member of the stirring member 500. For example, the first power receiving portion 710 includes a rubber ring arranged to rotate relative to the housing 200 along the first axis, and the rubber ring can simultaneously serve as the first member 711 and the second member 712. When it serves as the first member 711, it is in contact with the surface of the rotating member 100 and is driven to rotate, and when it serves as the second member 712, it transmits the received driving force to the next member by the friction force of the circumferential surface. Of course, the first power receiving portion 710 of the present embodiment can also be arranged as a gear or the like, which is within the implementation range of the present application.

[0061] In the embodiment shown in Figure 9 , the second member 712 includes an engaging tooth portion arranged in the first direction and a connecting portion 712a arranged as a cylindrical surface. The first member 711 is sleeved on the connecting portion 712a as a rubber ring, and thus the first member 711 and the second member 712 combine to form the integral first power receiving portion 710.

[0062] Of course, the first member 711 and the second member 712 can be arranged as different shafts or other linkage structures, and the connecting portion 712a can be arranged as a meshing tooth portion, a friction portion, a synchronous belt or the like, all of which can realize the transmission of the driving force between the first member 711 and the second member 712.

[0063] With reference to the above embodiment, the first member 711 and the second member 712 can be arranged as different shafts or other linkage structures, and the connecting portion 712a can be arranged as a meshing tooth portion, a friction portion, a synchronous belt or the like, all of which can realize the transmission of the driving force between the first member 711 and the second member 712. Figure 3 The second member 712 is provided with a linkage portion (such as the meshing tooth portion mentioned above) connected with the transmission portion 720. One part of the transmission portion 720 is connected with the second member 712, and the other part is connected with the second power receiving portion 530. The transmission portion 720 is located between the first power receiving portion 710 and the second power receiving portion 530 on the housing 200, one part of which is used to transmit the driving force generated by the third movement of the second member 712, and the other part is used to transmit the driving force to the stirring member 500, so as to realize the transmission of the driving force between the first power receiving portion 710 and the second power receiving portion 530. However, the transmission portion 720 does not intersect with the shaft coupling member 400, and is an independent power transmission chain arranged on the housing 200, so as to avoid the transmission of the driving force on the housing 200 caused by the shaft coupling member 400 in the container.

[0064] In the further expanded embodiment of the above embodiment, the second member 712 includes a first tooth portion 712b (i.e. the meshing tooth portion mentioned above) arranged circumferentially around the first axis, and the transmission portion 720 includes a linkage gear set 721 engaged with the first tooth portion 712b. The linkage gear set 721 includes at least one transmission gear, and the transmission gear close to the second member 712 includes a second tooth portion 721a which can be engaged with the first tooth portion 712b. The transmission portion 720 and the second member 712 are connected through the gear connection, so as to ensure the accuracy of the power transmission. Specifically, the transmission gears are engaged with each other, and the second power receiving portion 530 includes a power receiving gear rotating around a fifth axis different from the first axis, and the power receiving gear is engaged with one transmission gear of the linkage gear set 721, wherein the fifth axis also extends in the first direction. In this structure, the accurate transmission of the driving force between the transmission portion 720 and the stirring member 500 can be realized.

[0065] With reference to the above embodiment, the first member 711 and the second member 712 can be arranged as different shafts or other linkage structures, and the connecting portion 712a can be arranged as a meshing tooth portion, a friction portion, a synchronous belt or the like, all of which can realize the transmission of the driving force between the first member 711 and the second member 712. Figure 3 The second member 712 is provided with a linkage portion (such as the meshing tooth portion mentioned above) connected with the transmission portion 720. One part of the transmission portion 720 is connected with the second member 712, and the other part is connected with the second power receiving portion 530. The transmission portion 720 is located between the first power receiving portion 710 and the second power receiving portion 530 on the housing 200, one part of which is used to transmit the driving force generated by the third movement of the second member 712, and the other part is used to transmit the driving force to the stirring member 500, so as to realize the transmission of the driving force between the first power receiving portion 710 and the second power receiving portion 530. However, the transmission portion 720 does not intersect with the shaft coupling member 400, and is an independent power transmission chain arranged on the housing 200, so as to avoid the transmission of the driving force on the housing 200 caused by the shaft coupling member 400 in the container. Figure 5The housing 200 has a first end portion 240 and a second end portion 250 arranged along the first direction, the second end portion 250 is spaced apart from the first end portion 240 along the first direction, the first power receiving component is arranged at the first end portion 240, and the coupling 410 is arranged at the second end portion 250. Thus, two components capable of receiving driving force are arranged at the two end positions of the cartridge, respectively. The problem of space crowding caused by the newly added power receiving component arranged at the same end portion as the coupling 410 can be avoided. The linkage gear set 721 on the transmission portion 720 of the power transmission assembly 700 for transmitting driving force can be squeezed into the space occupied by the first gear 420 and the second gear 430, the space layout on the storage cartridge is more reasonable, the mutual influence between the two transmission chains can be avoided, and the miniaturization of the container and the selenium drum as a whole is facilitated, and the longitudinal and transverse dimensions are shortened.

[0066] In the embodiments shown in Figure 10 and Figure 11 , the connecting portion 510 includes a connecting shaft 511 rotatably arranged on the housing 200 about a fifth axis extending along the first direction. The first end portion 240 of the housing 200 is provided with a through hole for mounting the connecting shaft 511. The connecting shaft 511 passes through the through hole and is rotatably arranged on the housing 200. The stirring portion 520 includes a rod portion 521 and stirring blades (not shown in the figure) connected to the rod portion 521. The two ends of the rod portion 521 are respectively provided with engaging recesses 521a. The extending portion of the connecting shaft 511 passing through the through hole and extending into the developer storage cavity 210 is provided with a non-cylindrical surface, specifically two engaging planes extending along the penetrating direction. The extending portion can be inserted into the engaging recess 521a. Thus, the connecting portion 712a carries the rod portion 521 to rotate about the fifth axis when rotating about the fifth axis, and further drives the stirring blades to rotate, thereby realizing stirring.

[0067] In another embodiment, the first movement is set as reciprocating movement between a first position close to the developing roller 300 and a second position of the developing roller 300. For example, refer to Figures 14 to 16The stirring part 520 comprises a developer pushing member 522 attached to the bottom of the developer storage cavity 210, and the developer pushing member 522 is provided with an action surface 522b facing the developing roller 300. When the developer pushing member 522 moves from the second position to the first position, the action surface 522b moves towards the second direction to push the developer into the powder feeding channel 230 uniformly. When the selenium drum is in the imaging position in the electronic imaging device, the powder feeding channel 230 has a lower concave part below the bottom surface of the developer storage cavity 210, and the powder feeding roller 600 is arranged in the lower concave part to push the developer onto the developing roller 300. At this time, the developer pushing member 522 attached to the bottom of the developer storage cavity 210 can push the developer into the powder feeding channel 230 sufficiently. The developer pushing member 522 is provided with a plurality of convex strips 522a protruding from the bottom of the developer storage cavity towards the developing roller 300 in the first direction. The convex strip 522a is provided with the action surface 522b on the side facing the developing roller 300, and is provided with a smooth surface 522c on the side facing away from the developing roller 300. The smooth surface 522c has a smaller pushing effect on the developer than the action surface 522b. When the developer pushing member 522 is reset from the first position to the second position, the developer is less likely to be pushed back by the developer pushing member 522. Specifically, the inclination angle of the smooth surface 522c relative to the bottom surface of the developer storage cavity 210 is smaller than the inclination angle of the action surface 522b relative to the bottom surface of the developer storage cavity 210. The action surface 522b can be preferably implemented as 60° to 90°, and the smooth surface 522c can be preferably implemented as 45° to 10°. Of course, other angle planes or developer pushing structures can also be used, which are within the scope of the present application.

[0068] Continuing to refer to Figure 14 The connecting part 510 at one end of the shell 200 is provided with a first driving part 514 and a second driving part 515. The first driving part 514 is used to drive the stirring part 520 to move towards the developing roller 300 in the second direction to the first position. The second driving part 515 is used to drive the stirring part 520 to move away from the developing roller 300 in the third direction (e.g. the direction opposite to the second direction) to the second position. Figure 16to the second position, in this embodiment the first direction is opposite to the third direction, of course, other reset structure can be used to realize the reset from the first position to the second position, in which the third direction is not parallel or coincident with the second direction. The connecting part 510 is a connecting shaft 511 rotating around the fifth axis in this embodiment, the connecting shaft 511 is provided with the first driving part 514 and the second driving part 515 rotating around the fifth axis in the part of the connecting shaft 511 located in the developer storage cavity 210, in combination with the linkage gear set 721 structure mentioned in the foregoing embodiment, the connecting shaft 511 is driven by the linkage gear set 721 to rotate around the fifth axis along the fourth direction, in the process of the rotation of the connecting shaft 511, the first driving part 514 and the second driving part 515 are combined with the stirring part 520 in turn to move the stirring part 520 from the second position to the first position and from the first position to the second position, thereby realizing the reciprocating motion.

[0069] Specifically, when the connecting shaft 511 rotates along the fourth direction, the first driving part 514 drives the stirring part 520 until the stirring part 520 is moved to the first position, then the first driving part 514 is disengaged from the stirring part 520 and no longer exerts force on the stirring part 520, in the process of the continuous rotation of the connecting shaft 511, the second driving part 515 begins to engage the stirring part 520 and pushes the stirring part 520 from the first position to the second position, until the stirring part 520 reaches the second position and the second driving part 515 is disengaged from the stirring part 520 and no longer exerts force on the stirring part 520, and in the process of the continuous execution, the first driving part 514 and the second driving part 515 engage the stirring part 520 in turn to move the stirring part 520 back and forth between the first position and the second position, thereby realizing the stirring action required by pushing the developer.

[0070] In this embodiment, the first driving part 514 and the second driving part 515 are provided on the connecting shaft 511, and the first driving part 514 and the second driving part 515 are provided with the first driving part 514 and the second driving part 515, respectively, in the process of the rotation of the connecting shaft 511, the first driving part 514 and the second driving part 515 are combined with the stirring part 520 in turn to move the stirring part 520 from the second position to the first position and from the first position to the second position, thereby realizing the reciprocating motion. Figures 14 to 16The embodiment shown in the figure is taken as an example, the stirring part 520 comprises an access interval 523 and a first stress part 524 and a second stress part 525 arranged on both sides of the access interval 523, one of the first driving part and the second driving part comprises a first pushing surface 514a, and the other one comprises a second pushing surface 515a, when the connecting shaft 511 rotates around the fifth axis in the fourth direction, the first pushing surface 514a enters the access interval 523 and pushes the first stress part 524 to move the stirring part 520 in the first specified direction which is the same as the moving direction of the first pushing surface 514a, the first specified direction can be set as the second direction or the third direction, for example, when the axis around which the connecting shaft 511 rotates is arranged at the upper position of the stirring part 520, the first pushing surface 514a enters the access interval 523 at the lower position of the fifth axis, at this time, the tangent direction of the first pushing surface 514a is the second direction, which can push the stirring part 520 to move to the first position in the second direction, of course, the tangent direction of the first pushing surface 514a entering the access interval 523 can be set as the third direction, which can also push the stirring part 520 to move to the second position in the third direction; when the connecting shaft 511 rotates around the fifth axis in the fourth direction, the second pushing surface 515a enters the access interval 523 and pushes the second stress part 525 to move the stirring part 520 in the second specified direction which is opposite to the moving direction of the second pushing surface 515a, the third specified direction can be set as the third direction or the second direction, for example, when the axis around which the connecting shaft 511 rotates is arranged at the upper position of the stirring part 520, at this time, the tangent direction of the second pushing surface 515a is the second direction, which can push the stirring part 520 to move to the second position in the third direction, of course, the tangent direction of the second pushing surface 515a entering the access interval 523 can be set as the third direction, which can push the stirring part 520 to move to the first position in the second direction. Thus, no matter whether the first pushing surface 514a and the second pushing surface 515a are arranged on the first driving part 514 or the second driving part 515, the reciprocating movement structure of the stirring part 520 between the first position and the second position can be realized.

[0071] The structure ingeniously converts the one-way rotation force received from the power transmission assembly 700 into a reciprocating driving force in a direction perpendicular to the first direction, which can make the size design of the entire selenium drum more reasonable, appropriately shorten the height dimension and increase the available storage space inside the developer, and the front and rear pushing manner can solve the problems of uneven stirring at the end and poor pushing effect caused by the rotating stirring manner in the prior art, especially the defects of large pushing resistance and large pushing amount in the case of full amount of developer, and the problem of small pushing amount in the case of less developer, and the embodiment structure can more accurately and completely push the developer into the powder conveying channel 230 in a uniform manner, reducing the developer residue in the container.

[0072] The specific structure can be further referred to Figure 13 The stirring part 520 is provided with an access structure near the first end 240 and the second end 250, each of which comprises an access interval 523 and a first force receiving part 524 and a second force receiving part 525 on both sides of the access interval 523, the first force receiving part 524 has a first force receiving surface 524a protruding upward from the bottom surface of the developer storage cavity 210, the first force receiving surface 524a is preferably perpendicular to the bottom surface, the second force receiving part 525 is provided with a second force receiving surface 525a which is farther and farther away from the bottom surface in the direction away from the access interval 523, the second force receiving surface 525a is provided as a curved surface structure and can be concave, the first driving part 514 is provided as a strip-shaped protrusion in the radial direction of the fifth axis, the first pushing surface 514a is provided as a pushing surface on one side of the strip-shaped protrusion, and the second driving part 515 is provided as a cam structure, the second pushing surface 515a is provided as a pushing curved surface on the periphery of the cam structure away from the fifth axis, and the pushing curved surface is gradually away from the fifth axis in the opposite direction of the fourth direction, so that when the pushing curved surface accesses the access interval 523, the end position first contacts the second force receiving surface 525a and the contact position continues to move downward with the rotation of the connecting shaft 511, and a pushing force is generated to move the stirring part 520 in the second specified direction until the stirring part 520 is reset to the second position. This structure operates smoothly, and the engagement and disengagement between the stirring part 520 and the developer are not easily affected by the developer, and the driving is stable and reliable. In addition, when the pushing curved surface cooperates with the second force receiving surface 525a, the stirring part 520 can be first reset to the second position in the second specified direction in the process of gradually rotating and touching the second force receiving surface 525a, and then the stirring part 520 is moved from the second position to the first position in the first specified direction in the process of continuing to touch the second force receiving surface 525a, and is disengaged from the second force receiving part 525 at the intermediate position between the first position and the second position, and then the pushing surface of the first driving part 514 continues to push the stirring part 520 to move to the first position, which can also achieve the effect of reciprocating motion.

[0073] In addition, the embodiment of the present application also has another driving structure for the stirring part 500, which can be further referred to Figure 13, the connecting portion 510 includes a first connecting member 512 arranged at the first end portion 240 and a second connecting member 513 arranged at the second end portion 250, the first connecting member 512 is used to receive the first power from the first power receiving portion 710, and the second connecting member 513 is used to receive the second power from the coupling component 400, and the second connecting member 513 is movable relative to the housing 200 with the movement of the coupling member 410. Thus, the stirring portion 520 is driven by receiving the first power and the second power at the same time when performing the first movement, and the structure can avoid the problem of excessive local pressure caused by the transmission chain arranged at one end portion position, especially for the stirring structure in the container. When the developer in the developer storage cavity is in a sufficient state, the stirring portion 520 needs a large stirring force to overcome the resistance generated when stirring a large amount of developer, and the resistance will be further transmitted to the linkage portion of the stirring component 500 and the outside. The prior art is driven by a single end position of the coupling component 400, which has the defect of uneven stress, and it is easy to cause one-way deflection and affect the transmission stability of the transmission chain of the developing roller 300. In the embodiment, the connecting portion 510 receives the first power and the second power at both ends at the same time, which can avoid the phenomenon that the stirring component 500 is unbalanced in operation or even damaged due to excessive stress concentration at one end, and can stir uniformly and prolong the service life without affecting the movement of the developing roller 300 and the powder feeding roller 600. The structure is particularly applied to the reciprocating stirring portion 520 structure of the foregoing embodiment, which can drive the connecting members at both ends without the need for intermediate shaft linkage between the first connecting member 512 and the second connecting member 513, saves space and ensures uniform and stable power supply.

[0074] The first connecting member 512 and the second connecting member 513 can each include a connecting shaft 511 structure rotatably arranged in the housing 200, coaxially arranged in the first direction, and respectively receiving driving force from the power transmission assembly 700 and the coupling component 400 to perform rotary movement around the fifth axis. The connection structure of the second connecting member 513 and the power component can be a gear structure, which is connected with the transmission gear set of the coupling component 400. Of course, other power transmission structures can also be implemented, which are also within the scope of the present application.

[0077] In a specific embodiment, referring to Figure 3The detected piece 810 is a detection gear rotatable about a sixth axis extending in the first direction, the detection gear being connected with the second power receiving portion 530, and the detection gear is provided with a detection protrusion as the detection portion 811, wherein the detection protrusion is arranged on an end surface of the detection gear facing away from the housing 200 along the first axis and protrudes in a direction away from the housing 200 to be exposed on the outer side surface of the housing 200, when the container is assembled in the equipment body together with the processing device, the second movement performed by the detected piece 810 along with the first movement is a rotational movement about the sixth axis, and the activity range of the detection protrusion is a revolution movement about the sixth axis along with the movement of the detected piece 810.
