Description

Technical Field

[0001] The present invention relates to the technical field of electronic imaging, in particular to a developing box. Background Art

[0002] An electrophotographic image forming apparatus includes a developing cartridge that develops an electrostatic latent image on a photosensitive drum using toner. The developing cartridge includes a developing roller rotatably supported within its housing, and development is performed by supplying toner stored in the housing from the developing roller to the photosensitive drum.

[0003] The developing cartridge is usually installed in an image forming device in a detachable manner. Currently, there are two installation methods. One is that the developing cartridge is directly installed in the image forming device body, and the other is that the developing cartridge is first installed in a drum unit and then installed in the image forming device body together with the drum unit. Regardless of how the developing cartridge is installed, in order to enable the developing cartridge to be accurately identified by the image forming device, the existing developing cartridge is provided with a detection member for combining with a preset detection part in the image forming device and a power receiving member for receiving driving force from a power output member provided in the image forming device.

[0004] The detected part is driven by the driving force received by the driving head. When the detected part and the power receiving part are arranged on the same side, the driving force can be transmitted between the two via gears. When the detected part and the power receiving part are arranged on different sides, in the existing developer cartridge, the driving force is transmitted to the side where the detected part is installed via the stirring shaft installed in the developer cartridge, and then the driving force is transmitted to the detected part via gears. Obviously, in order to drive the detected part, for a structure where the detected part and the power receiving part are located on different sides of the developer cartridge, a set of gears needs to be installed on both sides of the developer cartridge. The installation of these gears not only increases the material cost of the developer cartridge, but also increases the assembly cost of the developer cartridge.

[0005] It can be seen that the existing developing cartridge is difficult and inconvenient to install or remove into the image forming device. The corresponding detection part structure is not only complex, but also has the problem that the developing cartridge cannot work normally due to difficulty in identification. Summary of the Invention

[0006] The object of the present invention is to provide a developing box. In this scheme, the detected component and the detection device are in a resistance connection, and there is no need to use complicated operations or structures to release the connection between the detected component and the detection device. Therefore, it can solve the problem of inconvenient operation caused by installing or removing the developing box into or from the image forming device. At the same time, it can effectively solve the problem that the developing box is not easy to identify due to the complex connection relationship between the detected component and the detection device, so as to ensure the normal operation of the developing box.

The rotation axes of the developing roller 131, the powder feed roller, and the stirring frame all extend along a first direction. The developing roller 131 is disposed at the powder outlet. The powder feed roller is disposed adjacent to the developing roller 131. The powder feed roller is closer to the fourth end 14 of the box body 1 than the developing roller 131. The stirring frame is used to stir the developer in the accommodating chamber to cause friction between the developer and prevent the developer from clumping. The first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0202] The transmission assembly is disposed at the first end 11 and includes a power receiving device 4 rotatably mounted on the first end 11 of the housing 1. The rotation axis of the power receiving device 4 is parallel to the first direction. The power receiving device 4 includes a coaxial, integrally formed drive gear 322 and a power receiving portion 41. The drive gear 322 is located closer to the first end 11 of the housing 1 than the power receiving portion 41 in the first direction. The power receiving portion 41 is configured to couple with a power output shaft on the image forming device to receive power output from the image forming device.

[0203] The transmission assembly also includes a developing gear 43, a powder feeding gear 44, a stirring gear set 24, and a first idler gear 47. A support column is integrally formed on the first end 11 of the housing 1 along a first direction. The developing gear 43 is coaxially fixedly mounted on the end of the developing roller 131 near the first end 11 of the housing 1. The powder feeding gear 44 is coaxially fixedly mounted on the end of the powder feeding roller near the first end 11 of the housing 1. The stirring gear set 24 is coaxially fixedly mounted on the end of the stirring frame near the first end 11 of the housing 1.

In the first direction, the large-diameter idler gear is closer to the first end 11 of the housing 1 than the small-diameter idler gear.

[0204] The developing gear 43, the powder feeding gear 44 and the large-diameter first idler gear are all meshed with the driving gear 322. The stirring gear set 24 is meshed with the small-diameter idler gear on the first idler gear 47. The meshing can be direct or indirect.

[0205] like Figures 7 to 10 As shown, the rotation axis of the power receiving device 4 is closer to the fifth end 15 and the fourth end 14 of the box body 1 than the rotation axis of the developing roller 131, and the rotation axis of the power receiving device 4 is closer to the third end 13 of the box body 1 than the rotation axis of the stirring frame.

[0206] The stirring gear assembly 24 consists of a first shaft sleeve 242, a second shaft sleeve 241, and a gear portion, which are coaxially and integrally formed. The diameter of the first shaft sleeve 242 is smaller than that of the second shaft sleeve 241, and the diameter of the second shaft sleeve 241 is smaller than that of the gear portion. The first shaft sleeve 242 is fixedly mounted at the end of the stirring frame. The end of the first shaft sleeve 242, which is away from the box body 1 in the first direction, extends into the second shaft sleeve 241. A support wall is integrally formed between the end of the first shaft sleeve 242, which is away from the box body 1 in the first direction, and the inner wall of the second shaft sleeve 241. An annular groove is formed between the outer surface of the first shaft sleeve 242, the inner surface of the second shaft sleeve 241, and the support wall. The first elastic member 181 is mounted in the annular groove and is sleeved on the first shaft sleeve 242. The first rotating member 21 is also mounted on the first shaft sleeve 242. The first rotating member 21 has an axial hole coaxially opened in the center. The first rotating member 21 is coaxially and rotatably mounted to the first shaft sleeve 242 through the axial hole. One end of the first elastic member 181 abuts against a side of the first rotating member 21 away from the box body 1 in the first direction, and the other end of the first elastic member 181 abuts against the support wall. An external thread is integrally formed on the outer surface of the first shaft sleeve 242, and an internal thread matching the external thread is integrally formed on the inner surface of the shaft hole. A transmission key 21a6 is also integrally formed on the outer surface of the first shaft sleeve 242, and the transmission key 21a6 extends along the first direction. The transmission key 21a6 is closer to the first end 11 of the box body 1 than the end of the external thread in the first direction. A keyway 21a5 matching the transmission key 21a6 is axially opened on the wall of the shaft hole. A stopper 33 ( Figure 6 As shown in FIG, the stopper 33 is in the same position in the first direction as the end of the external thread close to the box body 1 in the first direction. The stopper 33 is closer to the first end 11 of the box body 1 than the first idler wheel 47 in the first direction.

[0207] like Figures 7 to 10As shown, a first transmission protrusion is integrally formed on the first rotating member 21. The first transmission protrusion includes a first protrusion 21a1, a second protrusion 21a2, and a third protrusion 21a3 extending radially. The first protrusion 21a1, the second protrusion 21a2, and the third protrusion 21a3 are distributed along the circumference of the first rotating member 21. The surfaces of the first protrusion 21a1, the second protrusion 21a2, and the third protrusion 21a3 radially away from the rotation axis of the first rotating member 21 are the first contact surface, the second contact surface, and the third contact surface, respectively. The first contact surface, the second contact surface, and the third contact surface are all arc surfaces with the same radius and coaxial with the rotation axis of the first rotating member 21. The central angle subtended by the first contact surface is larger than that of the second and third contact surfaces. A fourth protrusion 21a4 extending in the radial direction is integrally formed on the first contact surface. The side of the fourth protrusion 21a4 that is radially away from the rotation axis of the first rotating member 21 is the fourth contact surface. The fourth contact surface is an arc surface coaxial with the rotation axis of the first rotating member 21. The central angle of the fourth contact surface is the same as the central angle of the first contact surface. The radius of the fourth contact surface is greater than the radius of the first contact surface, the second contact surface, and the third contact surface. A positioning hole is formed on the first protrusion 21a1 along the first direction. A positioning column 21b ( Figure 6 ), the positioning post 21b can be inserted into the positioning hole. In the first direction, the end of the positioning post 21b is closer to the first end 11 of the box body 1 than the transmission key 21a6. The positioning post 21b includes a first positioning post and a second positioning post formed in one piece, and the first positioning post is located on the end of the second positioning post away from the box body 1 in the first direction. The cross-sectional area of ​​the first positioning post in the second direction is smaller than that of the second positioning post. The positioning hole includes a first positioning hole 21a7 and a second positioning hole 21a8 that are connected, and the size of the first positioning hole 21a7 matches the first positioning post, and the size of the second positioning hole 21a8 matches the second positioning post. In the second direction, the positioning post 21b is located on the rear side of the rotation axis of the stirring frame, and the support post is located on the front side of the rotation axis of the stirring frame. The end of the stopper 33 close to the rotation axis of the first rotating member 21 in the second direction is located within the rotation trajectory of the first protrusion 21a1, the second protrusion 21a2, the third protrusion 21a3, and the fourth protrusion 21a4.

[0208] The transmission assembly also includes a first swing arm 22, which extends through the accommodating cavity in a first direction and extends out of the housing 1. One end of the first swing arm 22 is a force-bearing end, and the other end is a force-applying end. The force-bearing end of the first swing arm 22 is located at the first end 11 of the housing 1, while the force-applying end of the first swing arm 22 is located at the second end 12 of the housing 1. A first groove 112 and a second groove 123 are defined in the first end 11 and second end 12 of the housing 1, respectively. The first groove 112 and the second groove 123 extend in the second direction. The projections of the first groove 112 and the second groove 123 in the first direction overlap. An elastic film is formed between the first swing arm 22 and the first and second grooves 112 and 123 via overmolding. This elastic film seals the first and second grooves 112 and 123, preventing developer leakage. A pivot extending in the third direction is integrally formed on the inner surface of the fifth end 15 of the housing 1. The first swing arm 22 is rotatably mounted on the pivot. The pivot is located at the longitudinal center of the first swing arm 22. The force-bearing end of the first swing link 22 is located vertically above the first rotating member 21. A force-bearing protrusion 221 is integrally formed on the force-bearing end of the first swing link 22, and the lower end of the force-bearing protrusion 221 is located within the motion trajectory of the first protrusion 21a1, the second protrusion 21a2, the third protrusion 21a3, and the fourth protrusion 21a4.

[0209] like Figure 2 and Figure 5 As shown, the detected component 3 includes a third slider 31, and a slide rail 122 with an unclosed front end is integrally formed on the second protective cover 121. The third slider 31 is slidably mounted in the slide rail 122. The front end of the third slider 31 is the detected end 32. The detected end 32 can extend from the front end of the slide rail 122. A first lever 31a is integrally formed on the right side wall of the third slider 31, and the first lever 31a has a force-bearing surface, which is located in front of the force-applying end of the first rocker 22. A mounting hole 321 is integrally formed on the third slider 31, and a mounting seat 1221 is integrally formed in the slide rail 122. The mounting seat 1221 extends into the mounting hole 321, and a second elastic member 182 is installed between the rear side wall of the mounting hole 321 and the mounting seat 1221.

[0210] The detected component 3 has a first state and a second state. In the first state, the force-bearing end of the first swing arm 22 is closer to the fourth end 14 of the box body 1 than the force-applying end in the second direction. The force-bearing surface of the first lever 31a is supported by the force-applying end, causing the detected end 32 to extend out of the slide rail 122, and the second elastic member 182 to be in a stretched state.

[0211] In the second state, the force-bearing end of the first swing rod 22 is farther from the fourth end 14 of the box body 1 than the force-applying end in the second direction. The detected end 32 of the first lever 31a is located in the slide rail 122, and the second elastic member 182 does not undergo elastic deformation.

[0212] The power supply assembly includes a conductive member located at the second end 12 of the housing 1. The conductive member has an electrical receiving surface 51. The conductive member also has a first power supply terminal and a second power supply terminal. The first power supply terminal is electrically connected to the end of the developing roller 131 near the second end 12 of the housing 1, and the second power supply terminal is electrically connected to the end of the powder feed roller near the second end 12 of the housing 1. The electrical receiving surface 51 is configured to contact the power supply portion of the image forming device to receive electrical energy output by the image forming device and transmit the electrical energy to the developing roller 131 and the powder feed roller to form a bias voltage between the developing roller 131 and the powder feed roller. In the second direction, the electrical receiving surface 51 is located between the rotation axis of the stirring frame and the developing roller 131.

[0213] The identification component includes a storage medium and an electrical contact surface 5. The storage medium is used to store data, and the electrical contact surface 5 is used to contact and electrically connect with the identification contacts in the image forming device. The storage medium is fixedly mounted on the first protective cover 111, and the electrical contact surface 5 is fixedly mounted on the storage medium and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end surface of the storage medium. There is an intersection between the third direction and the electrical contact surface 5. The electrical contact surface 5 is located between the rotation axis of the developing roller 131 and the rotation axis of the stirring frame in the second direction. In the second direction, the distance between the electrical contact surface 5 and the rotation axis of the driving part is smaller than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame.

[0214] By adopting the design disclosed in this embodiment, it is possible to eliminate the need for a large number of transmission mechanisms to be designed for transmission at the second end 12 of the box body 1, thereby reducing the volume of the second end 12 of the box body 1 and facilitating the miniaturization of the developing device. Moreover, after reducing the transmission mechanism, the second protective cover 121 can also be made smaller, saving materials and space.

[0215] The following describes the operating process of the developing device disclosed in this embodiment. The developing device is installed on the drum assembly within the image forming device. The image forming device's power output shaft is connected to a power receiving device 4. Identification contacts within the image forming device contact electrical contact surface 5 and read information stored in the storage medium to identify the developing device's model, capacity, lifespan, and other information.

[0216] The developing device disclosed in this embodiment has a factory-set state. In this factory-set state, a surface of the first rotating member 21 that is distal to the first end 11 of the housing 1 in the first direction abuts against a surface of the stirring gear assembly 24 that is proximal to the first end 11 of the housing 1 in the first direction. The first elastic member 181 is compressed, and the force-bearing protrusion 221 of the first swing arm 22 contacts and is restrained by the first protrusion 21a1. In this factory-set state, the detected component 3 is in a first state. In this first state, the first swing arm 22 is non-parallel to the first direction. In the second direction, the force-bearing end of the first swing arm 22 is closer to the fourth end 14 of the housing 1 than the force-applying end. The force-bearing surface of the first lever 31a is supported by the force-applying end, causing the detected end 32 to extend out of the slide rail 122. The second elastic member 182 is in a stretched state.

[0217] When the developing device is installed on the drum assembly in the image forming device, the detected end 32 on the developing device in the initial state is in a state of extending out from the slide rail 122, so that the detected end 32 will contact the detection part in the image forming device and apply a thrust to the detection part, causing the detection part to generate an electrical signal, thereby causing the image forming device to detect that the developing device is installed.

[0218] When the image forming apparatus receives the print instruction, the image forming apparatus starts to output power to the power receiving apparatus 4, so that the power receiving apparatus 4 rotates around the image forming apparatus. Figure 4 The drive gear 322 rotates clockwise along with the power receiving device 4, driving the developing gear 43, the powder feeding gear 44, and the large-diameter idler gear to rotate counterclockwise. The small-diameter idler gear rotates counterclockwise along with the large-diameter idler gear. The small-diameter idler gear drives the stirring gear set 24 to rotate clockwise. This causes the developing roller 131, the powder feeding roller, and the stirring frame to start operating.

[0219] At the same time, the stirring gear assembly 24 drives the first sleeve 242 and the second sleeve 241 to rotate. Due to the friction between the external threads on the first sleeve 242 and the internal threads on the first rotating member 21, the first rotating member 21 rotates along with the first sleeve 242, and the first protrusion 21a1, second protrusion 21a2, third protrusion 21a3, and fourth protrusion 21a4 all rotate along with the first rotating member 21. The sidewall of the first protrusion 21a1 then abuts against the stopper 33, preventing the first rotating member 21 from continuing to rotate along with the first sleeve 242. At this point, the threads cause the first rotating member 21 to displace in the first direction relative to the first sleeve 242, moving the first rotating member 21 toward the box body 1. At this point, the force-bearing protrusion 221 remains in contact with the first contact surface on the first protrusion 21a1, maintaining the first rocker arm 22 in the first state.

[0220] Then, as the first sleeve 242 rotates, the first rotating member 21 continues to move in the first direction toward the housing 1, blocked by the stopper 33. After the first rotating member 21 disengages from the external threads of the first sleeve 242, the keyway 21a5 on the first rotating member 21 aligns with the drive key 21a6 on the first sleeve 242 and engages. Simultaneously, the surface of the first rotating member 21 closest to the housing 1 abuts against the positioning post 21b, preventing the first rotating member 21 from further displacement in the first direction. Driven by the drive key 21a6, the first rotating member 21 begins to rotate along with the first sleeve 242.

[0221] As the first sleeve 242 rotates, the first protrusion 21a1 disengages from the force-bearing protrusion 221 of the first swing lever 22. At this point, under the elastic force of the second elastic member 182, the detected member moves to the second state, so that the detected end 32 no longer pushes the detecting member, thereby ending the first push on the detecting member.

[0222] Then, as the first rotating member 21 rotates, the second protrusion 21a2 contacts and pushes the force-bearing protrusion 221 of the first rocker 22, causing the detected member to move to the first state. The detected end 32 of the third slider 31 pushes the detecting member again. The second protrusion 21a2 then disengages from the force-bearing protrusion 221. Under the elastic force of the second elastic member 182, the detected component 3 moves to the second state. The detected end 32 no longer pushes the detecting member, thus ending the second push on the detecting member.

[0223] Then, as the first rotating member 21 rotates, the third protrusion 21a3 contacts and pushes the force-bearing protrusion 221 of the first rocker 22, causing the detected component 3 to move to the first state. The detected end 32 of the third slider 31 pushes the detecting component again. The third protrusion 21a3 then disengages from the force-bearing protrusion 221. Under the elastic force of the second elastic member 182, the detected component 3 moves to the second state. The detected end 32 no longer pushes the detecting component, thus completing the third push on the detecting component.

[0224] Then, as the first rotating member 21 rotates, the first positioning hole 21a7 rotates until it is aligned with the first positioning post 21b. At this time, under the elastic force of the first elastic member 181, the first rotating member 21 moves along the first direction toward the box body 1. At the same time, the first positioning post is inserted into the first positioning hole 21a7. The first positioning hole 21a7 and the second positioning hole 21a8 are both arc-shaped, allowing the first positioning post to slide relative to the first positioning hole 21a7 within the first positioning hole 21a7. At the same time, because the cross-sectional area of ​​the first positioning post is smaller than that of the second positioning post, the second positioning post cannot enter the first positioning hole 21a7, causing the second positioning post to abut against the end surface of the first rotating member 21, preventing the first rotating member 21 from continuing to move in the first direction. Then, as the first rotating member 21 rotates, the fourth protrusion 21a4 contacts the force-bearing protrusion 221 of the first swing rod 22, and causes the detected component 3 to move to the first state. Since the radius of the fourth protrusion 21a4 is larger than the first protrusion 21a1, the second protrusion 21a2, and the third protrusion 21a3, when the first protrusion 21a1, the second protrusion 21a2, and the third protrusion 21a3 push the first swing rod 22, the third slider 31 moves to the first state at the first speed, and the fourth protrusion 21a4 has a faster linear speed, causing the detected component 3 to enter the first state at a second speed faster than the first speed, causing the detected end 32 to push the detection member for the fourth time, and then as the first rotating member 21 rotates, the fourth protrusion 21a4 contacts the force-bearing protrusion 221 of the first swing rod 22, and causes the detected component 3 to move to the first state. When the first rotating member 21 is rotated, the second positioning column is aligned with the second positioning hole 21a8. At this time, under the elastic force of the first elastic member 181, the first rotating member 21 moves along the first direction toward the direction close to the box body 1, so that the second positioning column enters the second positioning hole 21a8, and at the same time, the transmission key 21a6 is disengaged from the key slot 21a5, so that the first rotating member 21 can only generate a movement tendency under the action of the friction between the first shaft sleeve 242, and the side wall of the second positioning hole 21a8 is against the second positioning column 21b, thereby offsetting the friction between the first shaft sleeve 242 and the first rotating member 21, thereby preventing the first rotating member 21 from continuing to rotate, thereby achieving the positioning of the first rotating member 21.

[0225] Example 2

[0226] This embodiment discloses a process cartridge comprising a developer cartridge and a photosensitive element cartridge. The developer cartridge is provided with a detected component 3. The photosensitive element cartridge is provided with at least one power receiving device that can provide power to a photosensitive drum 81 on the photosensitive element cartridge. The power receiving device provided on the photosensitive element cartridge can also provide an external driving force to the developer cartridge, thereby rotating a developing roller 131 on the developer cartridge.

[0227] Figures 12 to 13A photosensitive element cartridge according to this embodiment includes a photosensitive frame 801 arranged along a first direction, and a power receiving device disposed on one side of the first direction. The power receiving device includes a first power receiving block 811 for receiving external power, and a photosensitive transmission portion 811a connected to the first power receiving block 811. A second power receiving block 812 is disposed adjacent to the first power receiving block 811 along a second direction. The second power receiving block 812 provides rotational power to the photosensitive drum 81 of the photosensitive element cartridge.

[0228] Figure 14 The figure shows an overall schematic diagram of the developer cartridge and photosensitive element cartridge in the process cartridge. The developer cartridge stores developer and is provided with a developing roller 131 that supplies developer to the photosensitive drum 81 on the photosensitive element cartridge. A chip is provided on the end of the developer cartridge body 1 in the first direction opposite the detected component 3. The chip has an electrical contact surface 5 that can be electrically connected to the image forming device, allowing the image forming device to identify or detect a new developer cartridge.

[0229] The developer cartridge has a first end 11 and a second end 12 in a first direction. Specifically, the developer cartridge includes a cartridge body 1, a developing roller 131, and a detected component 3. The detected component 3 is located on the cartridge body 1 near the second end 12. The detected component 3 protrudes from the cartridge body 1 and is configured to contact or separate from a detection toggle lever of an image forming device (not shown). Detection is triggered by a state change between the detected component 3 and the detection toggle lever, for example, establishing or disconnecting the two. When the detected component 3 loses contact with the detection toggle lever, i.e., disconnects the electrical connection, the image forming device can detect the developer cartridge based on this state change.

[0230] According to the present embodiment, the developing box receives the driving force of the image forming device through the power receiving device on the photosensitive element box. Then, the developing roller 131 on the developing box and the detected component 3 are driven to move. Figure 14 As shown, according to the initial state of the developing box before being matched with the photosensitive element box, when the developing box is installed into the photosensitive element box, the photosensitive transmission part 811a of the power receiving device on the photosensitive element box cooperates with the transmission gear group 45 of the developing roller 131 on the developing box, the powder feeding gear 44 of the powder feeding roller (not shown), and the stirring gear group 24 of the stirring frame (not shown).

[0234] like Figure 15As shown, a processing box includes a developing box and a photosensitive element box.

[0235] The photosensitive element box has a photosensitive frame 801 arranged along a first direction, and a power receiving device arranged on one side of the first direction. The power receiving device includes a power receiving portion 811 for receiving external power, and a photosensitive transmission portion 811a connected to the power receiving portion 811. The photosensitive transmission portion 811a can provide rotational power to the photosensitive drum 81 (not shown) of the photosensitive element box. A chip and a core frame supporting the chip are arranged on one side of the power receiving device in the first direction of the photosensitive element box. The chip and the core frame are located at the end of the photosensitive element box that is away from the photosensitive drum 81 (not shown) in the second direction. The chip has an electrical contact surface 5.

[0236] The developing box stores developer and is provided with a developing roller 131 for supplying developer to the photosensitive drum 81 (not shown) on the photosensitive element box. The developing box has a first end 11 and a second end 12 in the first direction. The developing box also includes a box body 1 and a detected component 3. The detected component 3 is provided at the second end 12 in the first direction of the developing box body 1, and a transmission component is provided relative to the first end 11 of the detected component 3. The transmission component includes a developing gear 43 that provides power to the developing roller 131, and a powder feeding roller that supplies powder to the developing roller 131. There is also a stirring frame (not shown) that stirs the developer in the box body 1, and a stirring gear set 24 that provides power to the stirring frame to make the developer in the box body 1 fluffy. At the same time, the transmission parts provide power to the detected component 3, which protrudes from the box body 1 and is used to contact or separate from the detection toggle lever of the image forming device (not shown). The detection is triggered by the state change between the detected component 3 and the detection toggle lever, for example, the two can be connected / disconnected. When the detected component 3 is disconnected from the detection toggle lever, the image forming device can perform detection on the developing box based on this state change.

[0237] When the developer cartridge is installed inside the photosensitive element cartridge, the photosensitive transmission portion 811a on the photosensitive element cartridge cooperates with the transmission gear set 45 of the developing roller 131, the powder feed gear 44 of the powder feed roller (not shown), and the stirring gear set 24 of the stirring frame (not shown). This causes the developing roller 131 on the developer cartridge to rotate. When the developer cartridge and photosensitive element cartridge are placed in an image forming apparatus, the transmission head of the image forming apparatus cooperates with the power receiving portion 41 on the photosensitive element cartridge, thereby driving the photosensitive drum 81 on the photosensitive element cartridge to rotate. Simultaneously, since the developer cartridge is installed inside the photosensitive element cartridge, its photosensitive transmission portion 811a cooperates with the transmission gear set 45 of the developing roller 131, the powder feed gear 44 of the powder feed roller (not shown), and the stirring gear set 24 of the stirring frame (not shown). This simultaneously transmits power to the detected component 3, causing the detected component 3 to disengage or contact the image forming apparatus, thereby enabling the detected component 3 to operate or not operate. Furthermore, since the chip is provided on the photosensitive element cartridge, when the developing cartridge and the photosensitive element cartridge are placed in an image forming device as a whole, electrical connection between the chip and the image forming device can be achieved.

[0238] Example 4

[0239] Figure 16 This embodiment shows another schematic diagram of the structure of the developer cartridge and photosensitive element cartridge within the process cartridge. Unlike the third embodiment, the photosensitive element cartridge is provided with a chip cartridge core holder. The power receiving portion 811 and photosensitive transmission portion 811a of the power receiving device are provided on the developer cartridge. Unless otherwise noted, all other components of this embodiment are identical to those of the third embodiment.

[0240] like Figure 16 As shown, a processing box includes a developing box and a photosensitive element box.

[0241] The photosensitive element cartridge has a photosensitive frame 801 arranged along a first direction, and a photosensitive drum 81. A drive head (not shown) can provide rotational power to the photosensitive drum 81 of the photosensitive element cartridge. A chip and a core frame supporting the chip are provided on one side of the photosensitive element cartridge in the first direction. The chip and core frame are located at an end of the photosensitive element cartridge that is farther away from the photosensitive drum 81 in the second direction.

[0242] The developing box stores developer and is provided with a developing roller 131 for supplying developer to the photosensitive drum 81 on the photosensitive element box. The developing box has a first end 11 and a second end 12 in the first direction. The developing box also includes a box body 1 and a detected component 3. The detected component 3 is provided at the second end 12 in the first direction of the developing box body 1, and a power receiving device is provided relative to the first end 11 of the detected component 3. The power receiving device includes a power receiving portion 811 for receiving transmission force from the image forming device, and a photosensitive transmission portion 811a connected to the power receiving portion 811 and transmitting power. There is also a stirring frame (not shown) for stirring the developer in the box body 1, and a stirring gear set 24 for providing power to the stirring frame to make the developer in the box body 1 fluffy. At the same time, the photosensitive transmission part 811a provides power to the detected component 3, and the detected component 3 protrudes from the box body 1, and is used to contact or separate from the detection toggle lever of the image forming device (not shown). The detection is triggered by the state change between the detected component 3 and the detection toggle lever. For example, the two can be connected / disconnected. When the detected component 3 is disconnected from the detection toggle lever, the image forming device can perform detection on the developing box based on this state change.

[0243] Example 5

[0244] Figures 17 to 19 The figure shows a schematic diagram of a novel detected component 3 of a developer cartridge. As shown in detail, the developer cartridge is removably mounted in an imaging device equipped with a detection device. The developer cartridge is equipped with a developing roller that supplies developer to the photosensitive drum 81 on the photosensitive element cartridge. The cartridge also includes a cartridge body 1. The cartridge body 1 has a first end 11 and a second end 12 in a first direction. The detected component 3 is mounted on the second end 12 of the developer cartridge body 1 in the first direction. A power receiving device 4 is disposed relative to the first end 11 of the detected component 3.

[0245] The power receiving device 4 and the detected component 3 are respectively located at the longitudinal ends of the box body 1, wherein the power receiving device 4 is used to receive driving force from the outside, and the detected component 3 is used to combine with the external detection device so that the developing box can be detected by the image forming device. The developing box also includes a first transmission rod 25 rotatably mounted in the box body 1, and the first transmission rod 25 is driven by the driving force received by the power receiving device 4; the detected component 3 is coaxially arranged with the first transmission rod 25.

[0246] More detailed information Figure 18 As shown, Figure 18 The figure shows that after removing the first protective cover 111 of the developing box and the cover on the box body 1, the connection relationship between the power receiving device 4 and the detected component 3 is shown. Figure 18As shown, the power receiving device 4 includes a power receiving portion 41 for receiving external transmission force and a photosensitive transmission portion for transmitting power. It also includes a developing gear 43 meshing with the photosensitive transmission portion, a powder feeding gear 44, a transfer gear, and a stirring gear set 24. The stirring gear set 24 includes a first stirring tooth portion, a second stirring tooth portion, and a detection gear 46 meshing with the second stirring tooth portion of the stirring gear set 24.

[0247] When the power receiving device 4 receives the external driving force of the image forming apparatus, the detected component 3 may be driven by the transmission gear set, and the detected component 3 is driven by the first transmission rod 25 .

[0248] When the developing cartridge is mounted on the imaging device, the detected component 3 is driven to rotate, so that the developing cartridge is detected by the imaging device. After the imaging device has finished detecting, the detected component 3 no longer needs to rotate. For this purpose, the detection gear 46 mounted on the other end of the first transmission rod 25 is set as a toothless gear, such as Figure 18 As shown, a portion of the circumferential surface of the detection gear 46 (the tooth-missing portion 461) is a smooth surface, that is, no teeth are provided at this portion. When the tooth-missing portion 461 of the detection gear 46 is opposite to the second stirring tooth portion in the stirring gear set 24, the detection gear 46 will no longer be driven by the second stirring tooth portion in the stirring gear set 24 and will stop rotating. Then, the first transmission rod 25 and the detected component 3 will also stop rotating. In fact, when the developing cartridge is working, it is necessary to receive not only the driving force from the image forming device, but also the electricity from the image forming device. In the developing cartridge of the present invention, the electricity receiving surface 51 ( Figure 19 The detecting end (not shown) is provided with a first direction, that is, the second end 12, and the electric receiving surface 51 supplies the power received from the image forming device to the developing roller 131 and the powder feeding roller at the same time. This design also helps to simplify the structure of the developing box. That is, there is no need to provide the electric receiving surface 51 for the developing roller 131 and the powder feeding roller (not shown) respectively. Only one electric receiving surface 51 is required. Figure 19 Also shown are the first transmission rod 25, the stirring frame 240 disposed within the developing cartridge body 1, and the stirring blades disposed on the stirring member. The detected component 3 is also provided with a plurality of first detection protrusions 34, which protrude in a first direction away from the cartridge body 1. In this embodiment, the power receiving surface 51 is configured as a power receiving member.

[0249] Preferably, the first transmission rod 25 and the stirring frame 240 are integrated, that is, they can be coaxially arranged. That is, only through the stirring frame 240, the developing box can also transmit power from the power receiving end to the detection end in the first direction.

[0250] Example 6

[0251] This embodiment is an improvement and variation of the fifth embodiment based on practical production issues. In the fifth embodiment, detection was triggered by rotating the detected component 3 about its axis in the first direction. In this embodiment, detection is triggered by extending or retracting the detected component 3 in the second direction. Unless otherwise noted, this embodiment is identical to the fifth embodiment.

[0252] Figure 20 3D is a perspective view of the developing box in this embodiment. Figure 20 As shown, the power receiving device 4 ( Figure 18 The transmission relationship between the power receiving device 4 and the detected component 3 is different from that of the above embodiments. It is achieved through the stirring frame 240 ( Figure 18 ) or a transmission shaft (such as the first transmission rod 25) and a gear set are transmitted to the second rotating member 26, and the detection end rotating member triggers the detected component 3, so that the detected component 3 moves telescopically in the third slide groove 260 under the action of the third elastic member 183. The developing box also includes a box body 1 for accommodating the developer, and an electric receiving surface 51 arranged on the same side of the detected component 3 in the first direction. The electric receiving surface 51 provides an electrical connection to the developing box by connecting to the image forming device. The detected component 3 is arranged on the end cover 6 of the developing box. The end cover 6 is provided with a third slide groove 260 extending along the second direction (i.e., the front-to-back direction).

[0253] Figure 21 This is a partially enlarged stereoscopic view of the processing box counting gear part after removing the end cover 6. Figure 21 As shown, the power receiving portion 41 at the first end 11 of the developer cartridge receives external transmission force, and transmits the force to the second rotating member 26 at the detection end of the developer cartridge in the first direction through the internal transmission shaft / rod or stirring frame 240 or developing roller 131 or powder feeding roller. The second rotating member 26 can be axially rotatably arranged on the cartridge body 1 along the first direction. The second rotating member 26 is provided with a plurality of second transmission protrusions 261. The second transmission protrusions 261 are located at one end of the second rotating member 26 in the direction away from the cartridge body 1 and have a tendency to push or maintain the protrusion 35 of the detected component 3 away from or toward the detection position of the image forming device. The detected component 3 also includes a fixing portion, one end of the third elastic member 183 is sleeved on the fixing portion, and the other end of the third elastic member 183 abuts against the third slide groove 260. It also includes a mating portion that cooperates with the third slide groove 260, and the detected component 3 can slide freely in the third slide groove 260. The third slide groove 260 is provided with a limiting portion on both sides of the second direction, which can protect the detected component 3 and prevent the detected component 3 from excessively popping out under the action of the third elastic member 183.

[0254] like Figure 22As shown, preferably, the movement direction of the detected component 3 is telescopic movement along the second direction. In a normal state, when the third elastic member 183 of the detected component 3 is in a free state, the detected portion 30 extends in the second direction to trigger the detection device of the image forming device.

[0255] When the second transmission protrusion 261 of the second rotating member 26 contacts the raised block 35 of the detected component 3, the detected component 3 is compressed and moves away from the detection device of the image forming device in the second direction. This means that the third elastic member 183 is compressed. At this time, the detected portion 30 is not in contact with the detection device of the image forming device in the second direction, i.e., in a de-triggered state. When the second transmission protrusion 261 of the second rotating member 26 is not in contact with the raised block 35, the detected portion 30 extends in the second direction under the action of the third elastic member 183. This continues to trigger the detection device of the image forming device, thereby enabling the image forming device to detect, count, or identify the developer cartridge.

[0256] It is conceivable that the third elastic member 183 can also be a component that can generate and restore deformation, such as a tension spring, a torsion spring, or an elastic sheet.

[0257] A more preferred embodiment is to directly cause the detected component 3 to telescope in the first direction. Specifically, a transmission rod can be directly extended from the power receiving end. The transmission rod can be extended and retracted in the first direction, and the third elastic member 183 can be omitted. A cam or lever can be used to enable the transmission rod to have a first position and a second position in the first direction. The second position extends from the developing cartridge body 1 in the first direction and can trigger the detection device of the imaging device. In addition, the extension and retraction of the detected component 3 in the first direction or the second direction to trigger the detection device of the imaging device, thereby enabling the imaging device to detect and identify the developing cartridge, should be included in the scope of protection of this embodiment.

[0258] Example 7

[0259] In this embodiment, another processing box is provided, and the unspecified parts are the same as the processing boxes in the fifth and sixth embodiments in structure.

[0260] The difference between this embodiment and the fifth or sixth embodiment is that the detected component 3 in the processing box of this embodiment swings relative to the processing box body.

[0261] Specifically, such as Figures 23 to 25As shown, as in the previous embodiment, the detected component 3 is located at one end of the developer cartridge in the first direction and receives power from the power receiving device 4 via a second rotating member 26. The second rotating member 26 is provided with a plurality of second transmission protrusions 261. This embodiment also includes a swinging member 27 for triggering the detection device. The swinging member 27 includes a first swinging end 272, a second swinging end 273, and a swinging ring 271. The swinging member 27 is mounted on the second protective cover 121 of the developer cartridge. The second protective cover 121 includes a space for accommodating the swinging member 27 and a rotating protrusion that cooperates with the swinging ring 271 of the swinging member 27. This allows the swinging member 27 to swing around the rotating protrusion within the range of the movement space.

[0262] The specific working principle is that the first swinging end 272 of the swinging member 27 extends along the first direction of the developing box and away from the developing box body 1, the second swinging end 273 is closer to the box body 1 relative to the first swinging end 272, and the second swinging end 273 can conflict with or disengage from the second transmission protrusion 261.

[0263] When the second swing end 273 contacts the second transmission protrusion 261, the swing member 27 swings around the rotating protrusion 61, and the first swing end 272 tilts up to contact the detection device of the image forming device, thereby triggering the image forming device to identify or detect the developing cartridge.

[0264] When the second swing end 273 is disengaged from the second transmission protrusion 261 , the swing member 27 swings around the rotating protrusion 61 , and the first swing end 272 is disengaged from the detection device of the image forming device, thereby not touching the detection device of the image forming device.

[0265] Example 8

[0266] Another structural feature that distinguishes this embodiment from the second, third, and fourth embodiments is that the photosensitive element cartridge is provided with a chip cartridge core frame and / or a component to be detected 3. The power receiving portion 41 and photosensitive transmission portion of the power receiving device 4 are provided on the developer cartridge. The power receiving device 4 receives the driving force of the image forming device. The powder cartridge's transmission lever activates the component to be detected 3 mounted on the photosensitive element cartridge, thereby interacting with a detector on the image forming device, thereby enabling the image forming device to detect and identify the powder cartridge. Other features are the same as those of the second, third, and fourth embodiments and will not be elaborated upon here.

[0267] Embodiment 9

[0268] This embodiment provides another process cartridge, which is different from the third embodiment to the fourth embodiment in that only a power receiving device 4 ( Figure 29 As shown), it provides rotational power to the photosensitive drum 81, and at the same time, through the cooperation of the developer box series gear set, it drives the developer box at the same time.

[0269] Please refer to Figures 26 to 29 .like Figure 26 , a process cartridge structure is shown, including a developer cartridge and a photosensitive element cartridge. The developer cartridge includes a cartridge body 1, a first end 11 disposed on the cartridge body 1 along a first direction, and a second end 12 opposite to the first end 11 in the first direction. The photosensitive element cartridge includes a power receiving device 4 disposed on one side of the photosensitive element cartridge close to the first end 11 in the first direction and away from the developer cartridge in the second direction. The power receiving device 4 includes a power receiving portion 41, which may be provided with a gear structure.

[0270] like Figure 27 The figure shows the position of the developing box before it is installed into the photosensitive element box. Figure 27 As shown, the developing box also includes a detected component 3, and a developing roller 131 for providing developer to the photosensitive element box. And a developing gear 43 ( Figure 28 ). And the developing gear 43 is located at one end of the developing box in the second direction close to the installation direction. Figure 27 As shown, the photosensitive element box also includes a receiving portion, which is mainly used to receive the developing cartridge when the developing cartridge is matched with the photosensitive element box along the installation direction. The photosensitive element box also includes a photosensitive frame 801 and a power receiving portion 41 provided at one end of the photosensitive frame 801 along the first direction. When the developing cartridge is completely installed in the photosensitive element box, the power receiving portion 41 ( Figure 26 As shown) cooperates with the developing gear 43, so that the power receiving device 4 on the photosensitive element box can input power to the developing roller 131 on the developing box.

[0271] Figure 28 The structure diagram of the developing box and the photosensitive element box at another angle is shown. The developing box is provided with a detected component 3 on one side opposite to the developing gear 43 along the first direction. Figure 29The diagram shows the partial structure of the photosensitive element cartridge, photosensitive frame 801, and developer cartridge upper body 1 after removal. In the figure, the photosensitive drum 81 receives external power through the power receiving device 4. The developing gear 43 receives power by meshing with the gears of the power receiving device 4, thereby driving the developing roller 131 to rotate. The developing roller 131 transfers toner from the developer cartridge body 1 to the photosensitive drum 81 via the powder feed roller 440. A first gear is provided on the side of the powder feed roller 440 near the developing gear 43. This first gear cooperates with the developing gear 43 to provide rotational power to the powder feed roller 440. A second gear is provided on the other side of the powder feed roller 440, located away from the developing gear 43 in the first direction. The second gear cooperates with the stirring gear set 24 via a first idler gear. The stirring gear set 24 is located at the end away from the developing gear 43 in the first direction. This gear provides power to the detected component 3. When the process cartridge as a whole begins operation within the image forming device, the detected component 3 on the developer cartridge is detected and identified by the image forming device.

[0272] Figure 30 The developing box is provided with a developing gear 43, and the developing gear 43 is connected to the photosensitive drum 81 ( Figure 29 ) power receiving device 4 (shown) Figure 29 The developing gear 43 also cooperates with the powder feeding gear 44 located on the same side of the developing cartridge to transmit power to the powder feeding roller 440. The powder feeding gear 44 transmits power to the stirring gear set 24 via the first idler gear. The stirring gear set 24 is located on the same side of the developing cartridge as the developing gear 43. This power input drives the stirring frame 240 to rotate, and transmits power to the detected component 3 through the other side of the developing cartridge opposite the developing gear 43.

[0273] Example 10

[0274] This embodiment provides another process cartridge. This embodiment differs from the ninth embodiment in that rotational power is provided to the photosensitive drum 81 solely through a power receiving device 4 on the photosensitive element cartridge. Simultaneously, the transmission gear on the other end of the photosensitive drum 81 cooperates with a series of gears on the other end of the developer cartridge to simultaneously drive the developing roller 131, powder feed roller 440, stirring frame 240, and detected component 3 of the developer cartridge. Details are as follows.

[0275] Figure 31 The figure shows the structure of the cooperation position between the developing box and the photosensitive element box and the photosensitive drum 81 in the processing box of the embodiment 10. Figure 32 As shown, it shows the processing box of embodiment 10, the third viewing angle position structure diagram of the cooperation position of the inside of the developing box and the photosensitive element box photosensitive drum 81.

[0276] As can be seen from the diagram, the photosensitive drum 81 is provided with a first photosensitive gear along a first direction for receiving external power, and a second photosensitive gear is provided at the other end relative to the first photosensitive gear. A developing gear 43 cooperates with the second photosensitive gear. A powder feed gear 44 cooperates with the developing gear 43. Rotation of the powder feed gear 44 drives the powder feed roller 440 to rotate. There are also a first idler gear, a second idler gear, and a stirring gear set 24 that cooperates with the second idler gear. The stirring gear set 24 drives the stirring frame 240 to rotate. The stirring frame 240 is provided with blades that stir the developer, ensuring that the developer is evenly distributed within the developer cartridge. A detected component 3 is provided on the same side as the developing gear 43. The detected component 3 cooperates with the stirring gear set 24 to achieve movement. When the processing cartridge as a whole begins operation within the image forming device, the detected component 3 on the developer cartridge is detected and identified by the image forming device.

[0277] Example 11

[0278] This embodiment provides another processing box, which is different from the fifth embodiment in that the driving end of the detected component 3 is arranged at one end of the developer box, and the detected part 30 of the detected component 3 is arranged at the other end of the developer box. It can transmit power from the driving end of the developer box to the end of the detected part 30 by telescopic movement and the like. In addition, the driving end is provided with multiple protrusions, while the detected part 30 of the detected component 3 has only one protrusion. The power receiving device 4 on the developer box provides rotational power to the developing roller 131, and at the same time, the powder feeding roller and the stirring frame 240 of the developer box (same as the fifth embodiment) are controlled by a series of transmission gear sets. Figure 19 shown) and the driving of the detected component 3.

[0279] Figure 33 As shown in FIG, a schematic diagram of a novel detection component 3 of a developing cartridge is disclosed. Figure 33As shown, a developing cartridge is removably mounted in an image forming device equipped with a detection device (not shown). The developing cartridge is provided with a developing roller 131 for supplying developer to a photosensitive drum 81 (same as in Example 5) on a photosensitive element cartridge. The developing cartridge also includes a cartridge body 1. The cartridge body 1 has a first end 11 and a second end 12 in a first direction. A detected component 3 is provided on the second end 12 of the developing cartridge body 1 in the first direction. The cartridge body 1 is provided with a power receiving device 4 and a chip (not shown) electrically connected to the image forming device at the first end 11 of the detected component 3. The developing roller 131 is also provided with a developing gear 43 for supplying power, and an electrode is provided on a side opposite to the developing gear 43 in the first direction. The electrode includes an electric receiving surface 51. As well as a first protective cover 111 at the driving end of the box body 1, and a second protective cover 121 at the detection end, and a power receiving device 4 and a detected component 3 respectively located at the longitudinal ends (first direction) of the box body 1, wherein the power receiving device 4 is used to receive driving force from the outside, and the detected component 3 is used to be combined with an external detection device (not shown) so that the developing box can be detected and identified by the imaging device or counted and identified. The developing box also includes a second transmission rod 28 (rotatably mounted in the box body 1) Figure 34 ), the second transmission rod 28 is driven by the driving force received by the power receiving device 4.

[0280] More detailed information Figure 34 As shown, Figures 34 to 35 This is a schematic diagram showing the position of the detected component 3 of the developer cartridge and the overall developer cartridge chamber structure after the developer cartridge cover is removed. As can be seen from the figure, the detected component 3 is located on one side of the developer cartridge body 1 along the first direction and is provided with a detected portion, which is a second detection protrusion 36. The second transmission rod 28 passes through both ends of the cartridge body 1. The second detection protrusion 36 is provided at one end of the second transmission rod 28. The second transmission rod 28 is provided with a driving portion at the other end relative to the second detection protrusion 36, which includes a connecting protrusion 281. The transmission assembly 2 includes a third rotating member 29 and a fourth elastic member 184, which is located between the third rotating member 29 and the side of the cartridge body 1 closest to the third rotating member 29. The third rotating member 29 can be coaxial with any gear in the developer cartridge transmission gear set, or it can be non-coaxial with any gear in the developer cartridge transmission gear set.

[0281] Figures 35 to 36 It can be seen that when part of the third rotating member 29 contacts the connecting protrusion 281, the fourth elastic member 184 is in a compressed state, and the second transmission rod 28 moves along the first direction close to the end of the detected component 3, thereby driving the second detection protrusion 36 to move in the direction away from the box body 1, thereby achieving trigger contact with the detection device (not shown). Figure 36In the middle, a chip is also provided at the same side of the box body 1 as the third rotating member 29. The chip includes an electrical contact surface 5, which can realize electrical connection with the electronic image forming device and is mainly used for the electronic image forming device to electrically identify or count the developing box.

[0282] More detailed information Figure 37 The specific structure of the third rotating member 29 of the developing box is shown, which includes a plurality of rotating protrusions 290, and at least one rotating protrusion 290 is projected in a fan shape along the first direction. When the fan-shaped rotating protrusion 290 conflicts with the connecting protrusion 281, the second transmission rod 28 can drive the second detection protrusion 36 to move away from the box body 1 along the first direction for a time as long as the time of other rotating protrusions 290. It can also be said that when at least one rotating protrusion 290 conflicts and interacts with the connecting protrusion 281, the second detection protrusion 36 and the image forming device detect for a long time. And through the action of the fourth elastic member 184, the second detection protrusion 36 can realize axial telescopic movement along the first direction.

[0283] A more accurate understanding is that the time when the second detection protrusion 36 and the image forming device are triggered by the detection is determined by the time when the different shapes of the rotating protrusion 290 interfere with the connecting protrusion 281 and interact with the fourth elastic member 184 .

[0284] Figure 38 The third rotating member 29 is shown in more detail. The third rotating member 29 includes a rotating protrusion 290, at least one rotating tooth portion 294, and at least one rotating toothless portion 295. The third rotating member 29 also includes a rotating shaft 296, the axial direction of which is parallel to the first direction. When the developing cartridge's transmission gear assembly 45 drives the rotating tooth portion 294 of the third rotating member 29 to rotate, the multiple rotating protrusions 290 can rotate along the axial direction of the rotating shaft 296, thereby interfering with the connecting protrusion 281, thereby driving the second transmission lever 28 and the second detection protrusion 36 to operate. This allows the second detection protrusion 36 to trigger detection of the image forming device.

[0285] Example 12

[0286] This embodiment provides another process cartridge. The difference from the eleventh embodiment is that the driving end of the detected component 3 is arranged at one end of the developer cartridge, and the detected portion 30 is arranged at the other end of the developer cartridge. It can transmit power from the driving end of the developer cartridge to the detected portion 30 by telescopic movement or other means. In addition, the driving end is provided with multiple protrusions, while the detected portion 30 has only one protrusion. Through the power receiving device 4 on the developer cartridge (same as the eleventh embodiment, Figure 33 ), provides rotational power to the developing roller 131, and at the same time drives the powder feeding roller, stirring frame 240 and detected component 3 of the developing box through a series of transmission gear sets.

[0287] More detailed information Figure 39 As shown, unlike the eleventh embodiment, a fifth elastic member 185 is provided at one end of the detected component 3. The elastic action of the fifth elastic member 185 enables the second transmission rod 28 and the detected component 3 to reciprocate and extend along the first axis, thereby triggering detection between the second detection protrusion 36 and the image forming device.

[0288] Figures 40 to 41 The first state diagram of the detected component 3 in the embodiment 12 is shown, and the detected component 3 is in the structure diagram of the position of the detection device 7. When in the first position, the tip of the second detection protrusion 36 of the detected component 3 contacts the detection device 7 in the first direction, thereby Figure 40 It is observed that there is a certain gap between the detected component 3 and the detection device 7 in the first direction.

[0289] Figures 42 to 43 The second state diagram of the detected component 3 is shown, and the detected component 3 cooperates with the detection device 7 in the figure. When in the second position, the non-pointed end of the second detection protrusion 36 of the detected component 3 contacts the detection device 7. Figure 42 There is no gap between the first direction and the detection device 7 .

[0290] Example 13

[0291] This embodiment provides another process cartridge. Unlike the twelfth or eleventh embodiments, the drive end of the detected component 3 is located at one end of the developer cartridge, while the detected component 3 is located at the other end. This allows for rotational transmission of power from the drive end of the developer cartridge to the detected component 3. Furthermore, the drive end is provided with multiple protrusions, while the detected component 3 has only one protrusion. The power receiving device 4 on the developer cartridge provides rotational power to the developing roller 131. Simultaneously, a series of transmission gears drives the developer cartridge's powder feed roller, agitator frame 240, and detected component 3.

[0292] Figure 44 FIG. 1 shows a structural diagram of the operation of the detected component 3 in Example 13. The second transmission rod 28 has a transmission protrusion 281, which is in transmission connection with the power receiving device 4. The driving force provided by the power receiving device 4 acts on the transmission protrusion 281, causing the transmission protrusion 281 to drive the second transmission rod 28 to generate displacement in the first direction.

[0293] Specifically, it can be seen from the figure that the detected component 3 can rotate around the second transmission rod 28, and a transmission protrusion 282 is provided at the transmission end of the second transmission rod 28. One end of the transmission protrusion 282 is fixed to the second transmission rod 28, and the other end is freely extended to the position of the third rotating member 29, and can contact or disengage with the rotating protrusion 290. A fifth elastic member 185 is provided near the transmission protrusion 282 (here, the fifth elastic member 185 can preferably have a torsion spring structure. When the third rotating member 29 receives an external transmission force through the rotating tooth portion 294, the rotating protrusion 290 rotates around the rotating shaft 296, and then interacts with the contacting transmission protrusion 282, driving the second transmission rod 28 to rotate, and then driving the detected component 3 to rotate. The second detection protrusion 36 on the detected component 3 interacts with the detection device 7. In this way, the detection triggering of the second detection protrusion 36 and the image forming device is realized, and the first trigger state is output.

[0294] Figure 45 The diagram shows the structure of the detected component 3 in the second working position in the thirteenth embodiment. When the third rotating member 29 receives external transmission force through the rotating tooth portion 294, the rotating protrusion 290 rotates about the rotating axis 296, interacting with the interfering transmission protrusion 282, driving the second transmission rod 28 to rotate, and in turn driving the detected component 3 to rotate, disengaging the second detection protrusion 36 on the detected component 3. This achieves detection triggering between the second detection protrusion 36 and the image forming device, thereby outputting the second trigger state.

[0295] Example 14

[0296] like Figures 46 to 60 As shown, this embodiment discloses a developing device, which can be detachably mounted on a drum assembly in an image forming device. The developing device includes a box body 1, a developing assembly, a transmission assembly 2, an identification assembly, a detected assembly 3, a power supply assembly, a first protective cover 111 and a second protective cover 121.

[0297] In the following descriptions of directions, perpendicular to Figure 46 When viewed from the center of the paper, Figure 46 The left side of the middle paper is left, Figure 46 The right side of the middle paper is right, Figure 46 The upper side of the paper is the top. Figure 46 The lower side of the middle paper is the bottom. Figure 46 The near side of the middle paper is the front, Figure 46 The far side of the middle paper is the back. The left-right direction is an embodiment of the first direction, the front-back direction is an embodiment of the second direction, and the up-down direction is an embodiment of the third direction.

[0298] The box body 1 has a chamber for accommodating developer. The box body 1 has a first end 11 and a second end 12 arranged opposite each other in a first direction. The box body 1 has a third end 13 and a fourth end 14 arranged opposite each other in a second direction. The box body 1 has a fifth end 15 and a sixth end 16 arranged opposite each other in a third direction. The box body 1 is provided with a powder outlet at the third end 13. The box body 1 is provided with a handle 141 at the fourth end 14.

[0299] The developing assembly includes a developing roller 131, a powder feed roller, and a stirring frame. These rollers are rotatably mounted within the receiving chamber between the first end 11 and the second end 12. The rotational axes of the developing roller 131, the powder feed roller, and the stirring frame extend along a first direction. The developing roller 131 is positioned at the powder outlet. The powder feed roller is positioned adjacent to the developing roller 131. The powder feed roller is closer to the fourth end 14 of the cartridge body 1 than the developing roller 131. The stirring frame is used to stir the developer within the receiving chamber to provide friction and prevent clumping.

[0300] The transmission assembly is disposed at the first end 11 and includes a power receiving device 4 rotatably mounted on the first end 11 of the housing 1. The rotation axis of the power receiving device 4 is parallel to the first direction. The power receiving device 4 includes a coaxial, integrally formed drive gear and a power receiving portion 41. The drive gear is closer to the housing 1 than the power receiving portion 41 in the first direction. The power receiving portion 41 is configured to couple with a power output shaft on the image forming device to receive power output from the image forming device.

[0301] like Figures 47 to 49 As shown, the transmission assembly also includes a developing gear 43, a powder feeding gear 44, a stirring gear set 45, a first idler gear 47, a second idler gear 472, a third idler gear 473, and a fourth idler gear 474. The developing gear 43 is coaxially fixedly mounted on the end of the developing roller 131 near the first end 11 of the box body 1. The powder feeding gear 44 is coaxially fixedly mounted on the end of the powder feeding roller near the first end 11 of the box body 1. The stirring gear set 45 is coaxially fixedly mounted on the end of the stirring frame near the first end 11 of the box body 1. The stirring gear set 45 includes a large-diameter stirring gear set and a small-diameter stirring gear set. In the first direction, the small-diameter stirring gear set is closer to the box body 1 than the large-diameter stirring gear set.

[0302] The first idler gear 47, the second idler gear 472, the third idler gear 473, and the fourth idler gear 474 are all rotatably mounted on the first end 11 of the housing 1. The rotation axes of the first idler gears 47, 472, 473, and 474 are all parallel to the first direction. The first idler gear 47 includes a large-diameter first idler gear and a small-diameter first idler gear. In the first direction, the large-diameter first idler gear is closer to the housing 1 than the small-diameter first idler gear. The fourth idler gear 474 includes a sheave 48 and a small-diameter fourth idler gear. In the first direction, sheave 48 is farther from the housing 1 than the small-diameter fourth idler gear. The diameter of the small-diameter fourth idler gear is smaller than that of sheave 48.

[0303] The developing gear 43, the powder feeding gear 44, and the first large-diameter idler gear all mesh with the drive gear. The large-diameter stirring gear set meshes with the first small-diameter idler gear. The small-diameter stirring gear set meshes with the second idler gear 472, which meshes with the third idler gear 473, which meshes with the fourth small-diameter idler gear. The meshing can be direct or indirect. The rotation axis of the power receiving device 4 is closer to the fifth end 15 and the fourth end 14 of the box body 1 than the rotation axis of the developing roller 131. The rotation axis of the power receiving device 4 is closer to the third end 13 of the box body 1 than the rotation axis of the stirring frame.

[0304] like Figure 54As shown, the transmission assembly also includes a third rotating member 29, whose rotation axis is parallel to the first direction. A third sleeve 299 is coaxially integrally formed on the third rotating member 29. The third rotating member 29 is rotatably mounted on a first support shaft integrally formed on the first end 11 of the housing 1 via the third sleeve 299. Part of the third sleeve 299 is located on the side of the third rotating member 29 that is farther from the housing 1 in the first direction. Another part of the third sleeve 299 is located on the side of the third rotating member 29 that is closer to the housing 1 in the first direction. An accelerating protrusion 297 is integrally formed on the third sleeve 299. The accelerating protrusion 297 extends radially along the third rotating member 29 and has a curved surface. A second support shaft is integrally formed on the first end 11 of the housing 1. Mounted on the second support shaft is an accelerating member, a torsion spring 190, with one end being a fixed end and the other end being an accelerating end. A limiting protrusion is integrally formed on the first end 11 of the box body 1, and a first bent portion is provided on the fixed end of the torsion spring 190. The limiting protrusion is used to block the movement of the first bent portion, thereby positioning the fixed end of the torsion spring 190. The accelerating end of the torsion spring 190 extends to the side of the third rotating member 29 away from the box body 1. The accelerating end of the torsion spring 190 abuts against the outer surface of the third shaft sleeve 299. A second bent portion is integrally formed on the accelerating end of the torsion spring 190. The bending angle of the second bent portion is the same as the angle between the arc surface on the accelerating protrusion 297 and the circumferential surface of the third shaft sleeve 299. This allows the second bent portion to fit into the angle between the arc surface on the accelerating protrusion 297 and the circumferential surface of the third shaft sleeve 299, thereby positioning the third rotating member 29 and preventing the third rotating member 29 from rotating due to external vibrations, shaking, or changes in the posture of the developer box.

[0305] The third rotating member 29 has a plurality of cylindrical pins 298 integrally formed on its end surface facing away from the housing 1 in the first direction. In this embodiment, there are twenty-two cylindrical pins 298, which are evenly spaced along the circumference. A notch 2971 is defined between a pair of adjacent cylindrical pins 298. The spacing between the two cylindrical pins 298 on either side of the notch 2971 is greater than the spacing between the other cylindrical pins 298 and the adjacent cylindrical pins 298. The notch 2971 is located on the side of the third rotating member 29 opposite the accelerating protrusion 297 in the radial direction.

[0306] The third rotating member 29 has a first protrusion 291, a second protrusion 292, and a third protrusion 293 integrally formed on the end surface of the third rotating member 29 that is closest to the housing 1 in the first direction. The first protrusion 291, the second protrusion 292, and the third protrusion 293 are all arranged along the circumference of the end surface of the third rotating member 29 that is closest to the housing 1. The surfaces of the first protrusion 291, the second protrusion 292, and the third protrusion 293 that are radially away from the third sleeve 299 are the first contact surface, the second contact surface, and the third contact surface, respectively. The first, second, and third contact surfaces are all arcuate surfaces. The arc length corresponding to the first contact surface is longer than that of the second and third contact surfaces.

[0307] This embodiment also includes a sixth elastic member 186. The transmission assembly 2 includes a second rocker arm 202. A groove is integrally formed on the fifth end 15 of the housing 1. The groove extends in the first direction. A pivot axis 39 is integrally formed within the groove along the third direction. The second rocker arm 202 is rotatably mounted on the pivot axis 39, with the rotation axis of the second rocker arm 202 parallel to the third direction. Both ends of the second rocker arm 202 extend out of the groove. The end of the second rocker arm 202 closest to the first end 11 of the housing 1 serves as the driven end, located along the motion trajectory of the first protrusion 291, the second protrusion 292, and the third protrusion 293. The end of the second rocker arm 202 closest to the second end 12 of the housing 1 serves as the transmission end. The detected assembly 3 includes a second detection protrusion 36, which extends in the second direction and is integrally fixed to the transmission end of the second rocker arm 202. In this embodiment, the front end of the second detection protrusion 36 serves as the detected end. A support portion is integrally formed on the second rocker arm 202, and the support portion is located between the second detection protrusion 36 and the second end 12 of the box body 1. A mounting seat 1221 is integrally formed on the second end 12 of the box body 1. One end of the sixth elastic member 186 is fixedly mounted in the mounting seat 1221, and the other end of the sixth elastic member 186 is against the support portion. A second protective cover 121 is fixedly mounted on the second end 12 of the box body 1 by means of a buckle or a screw, and a guide rail 122 extending in the second direction is integrally formed on the second protective cover 121. The second detection protrusion 36 is located in the guide rail 122 and can move along the extension direction of the guide rail 122. The end of the second detection protrusion 36 close to the developing roller 131 in the second direction is the detected end. The detected end is used to trigger the detection device in the image forming device.

[0308] The detected component 3 has a first state and a second state.

[0309] In the first state, the second swing arm 202 forms an angle with the first direction, the sixth elastic member 186 is compressed, and the detected end of the second detection protrusion 36 pushes the detection device 7 in the image forming device. The projection of the driven end of the second swing arm 202 in the third direction is located behind the projection of the rotation axis of the third rotating member 29 in the third direction.

[0310] In the second state, the second swing arm 202 is parallel to the first direction, the elastic potential energy of the sixth elastic member 186 is fully released, and the detected end of the second detection protrusion 36 does not contact the detection device 7 within the image forming apparatus. The detected end in the second state is farther from the developing roller 131 in the second direction than in the first state. The projection of the driven end of the second swing arm 202 in the third direction coincides with the projection of the rotation axis of the third rotating member 29 in the third direction.

[0311] The power supply assembly includes a conductive member located at the second end 12 of the housing 1. The conductive member has an electrical receiving surface 51. The conductive member also has a first power supply terminal and a second power supply terminal. The first power supply terminal is electrically connected to the end of the developing roller 131 near the second end 12 of the housing 1, and the second power supply terminal is electrically connected to the end of the powder feed roller near the second end 12 of the housing 1. The electrical receiving surface 51 is configured to contact the power supply portion of the image forming device to receive electrical energy output by the image forming device and transmit the electrical energy to the developing roller 131 and the powder feed roller to form a bias voltage between the developing roller 131 and the powder feed roller. In the second direction, the electrical receiving surface 51 is located between the rotation axis of the stirring frame and the developing roller 131.

[0312] The identification component includes a storage medium and an electrical contact surface 5. The storage medium is used to store data, and the electrical contact surface 5 is used to contact and electrically connect with the identification contacts in the image forming device. The storage medium is fixedly mounted on the first protective cover 111, and the electrical contact surface 5 is fixedly mounted on the storage medium and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end surface of the storage medium. There is an intersection between the third direction and the electrical contact surface 5. The electrical contact surface 5 is located between the rotation axis of the developing roller 131 and the rotation axis of the stirring frame in the second direction. In the second direction, the distance between the electrical contact surface 5 and the rotation axis of the power receiving device 4 is smaller than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame.

[0313] The following describes the operating process of the developing device disclosed in this embodiment. The developing device is installed on the drum assembly within the image forming device. The power output shaft of the image forming device is connected to the power receiving device 4. The identification contact within the image forming device contacts the electrical contact surface 5 and reads the information stored in the storage medium to identify the model, capacity, lifespan, and other information of the developing device. Simultaneously, the third rotating member 29 is in its initial position. In this initial position, the first contact surface of the first protrusion 291 contacts the driven end of the second rocker 202. At this point, the detected component 3 is in the first state, and due to the obstruction of the first contact surface, the elastic force of the sixth elastic member 186 cannot drive the second rocker 202 to a state parallel to the first direction. Therefore, as the developing device is installed within the drum assembly, the detected end of the second detection protrusion 36 contacts and pushes against the detection device within the image forming device, causing the developing device to be detected by the image forming device.

[0314] Then the power output shaft of the image forming device outputs power to the power receiving device 4, so that the driving part moves along the Figure 48 When describing the direction of rotation below, clockwise or counterclockwise is used as Figure 48 As a reference. The driving gear rotates clockwise, driving the developing gear 43, the powder feeding gear 44, and the large-diameter first idler gear to rotate counterclockwise. The small-diameter first idler gear rotates counterclockwise along with the large-diameter first idler gear, and the small-diameter first idler gear drives the large-diameter stirring gear group to rotate clockwise. The small-diameter stirring gear group rotates clockwise along with the large-diameter stirring gear group, and the small-diameter stirring gear group drives the second idler gear 472 to rotate counterclockwise. The second idler gear 472 drives the third idler gear 473 to rotate clockwise. The third idler gear 473 drives the small-diameter fourth idler gear to rotate counterclockwise. The grooved wheel 48 rotates counterclockwise along with the small-diameter fourth idler gear. The grooved wheel 48 cooperates with the cylindrical pin 298 on the third rotating member 29 to drive the third rotating member 29 to rotate clockwise at the first speed.

[0315] like Figure 54 and Figure 55 As shown, when the third rotating member 29 is in its initial position, the first cylindrical pin 298 behind the notch 2971 engages with the sheave 48. As the third rotating member 29 rotates, the first contact surface of the first protrusion 291 no longer contacts the driven end of the second swing arm 202. At this point, under the elastic force of the sixth elastic member 186, the second swing arm 202 moves to its second position, and the detected end no longer pushes against the detection device within the image forming apparatus.

[0316] As the third rotating member 29 continues to rotate, the second protrusion 292 pushes the driven end so that the driven end contacts the second contact surface of the second protrusion 292, thereby moving the detected component 3 to the first state, and the detected end pushes the detected component 3 again.

[0317] As the third rotating member 29 continues to rotate, the second contact surface of the second protrusion 292 no longer contacts the driven end. At this time, under the action of the elastic force, the second swing arm 202 moves to the second state, and the detected end no longer pushes the detection device in the image forming device.

[0318] As the third rotating member 29 continues to rotate, the third protrusion 293 pushes the driven end so that the driven end contacts the third contact surface of the third protrusion 293, thereby causing the detected component 3 to move to the first state, and the detected end pushes the detection device 7 in the image forming device again.

[0319] As the third rotating member 29 continues to rotate, the third contact surface of the third protrusion 293 no longer contacts the driven end. At this time, under the action of the elastic force, the second swing arm 202 moves to the second state, and the detected end no longer pushes the detection device in the image forming device.

[0320] As the third rotating member 29 continues to rotate, the accelerating protrusion 297 pushes the accelerating end of the torsion spring 190 , causing the torsion spring 190 to elastically deform and accumulate elastic potential energy.

[0321] The notch 2971 on the third rotating member 29 then moves to the position where the cylindrical pin 298 engages the sheave 48, preventing the cylindrical pin 298 from further engaging with the sheave 48 and preventing the power from the sheave 48 from being transmitted to the third rotating member 29. Simultaneously, the stored elastic potential energy of the torsion spring 190 is released, and the accelerating end of the torsion spring 190 pushes against the curved surface of the accelerating protrusion 297, causing the third rotating member 29 to rotate at a second speed that is faster than the first speed. This causes the first protrusion 291 to move the driven end at a faster speed, with the speed of the first protrusion 291 moving the driven end greater than the speed of the second and third protrusions 292, 293. This causes the detected component 3 to enter the first state, where the detected end pushes against the detection device within the image forming device at a faster speed. This causes the speed detection component within the image forming device to detect the increase in the moving speed.

[0322] The second bent portion on the accelerating end of the torsion spring 190 is inserted into the angle between the arc surface on the accelerating protrusion 297 and the third sleeve 299, so that the third rotating member 29 is positioned. At this time, the position of the third rotating member 29 is the final position, the first contact surface is in contact with the driven end, and the detected component 3 is in the first state.

[0323] By varying the number of protrusions on the third rotating member 29, different shifting times can be achieved, thereby adapting to different image forming devices. By changing the arc lengths or the ratio of the arc lengths of the first, second, and third contact surfaces of the third rotating member 29, the duration of the first state can be varied. By varying the arc lengths or the ratio of the arc lengths between the first, second, and third protrusions 291, 292, and 293, the duration of the second state can be varied.

[0324] Through the above design, the second end 12 of the box body 1 does not need any transmission components, which greatly reduces the volume of the second end 12 of the box body 1 and is conducive to the miniaturization of the developing device.

[0325] Example 15

[0326] Developer cartridges, such as Figures 61 to 70 As shown, it is installed in an image forming device having a detection device 7, which includes: a box body 1, a power receiving device 4, a first moving rod 203, a transmission component 2, and a detected component 3, specifically as follows:

[0327] like Figure 62As shown, the box body 1 is used to store the developer; the power receiving device 4 is provided on the box body 1, which can receive the driving force from the image forming device;

[0328] The power receiving device 4 includes: a driving gear and a stirring frame gear, specifically as follows:

[0329] The driving gear is arranged on the box body 1, which can receive driving force from the image forming device, and the driving gear is respectively connected to the developing gear and the powder feeding gear; the stirring frame gear is arranged on the box body 1, which is connected to the driving gear; thus, this scheme provides a specific implementation of the power receiving device 4, which can be adapted to this scheme.

[0330] The first moving rod 203 is slidably connected to the box body 1 ; a first sliding groove 101 is defined on the box body 1 , and the first moving rod 209 is slidably connected in the first sliding groove 101 .

[0331] The transmission assembly 2 is connected to the power receiving device 4 and the first moving rod 203, and is capable of converting the rotational force of the power receiving device 4 into a driving force for the first moving rod 203;

[0332] Among them, such as Figure 62 As shown, the transmission assembly 2 includes: a fourth rotating member 205, a first oblique push block 205a, and a second oblique push block 205b, specifically as follows:

[0333] The fourth rotating member 205 is rotatably mounted on the housing 1 and is in transmission connection with the power receiving device 4;

[0334] A first inclined push block 205a is disposed on the fourth rotating member 205 and has a first inclined surface 205a1;

[0335] The second inclined push block 205b is provided at the end of the first moving rod 209 and has a second inclined surface 205b1;

[0336] The first inclined surface 205a1 and the second inclined surface 205b1 are in contact with each other; preferably, in this embodiment, the inclination angle between the first inclined surface 205a1 and the second inclined surface 205b1 is an acute angle, preferably 45 to 80 degrees.

[0337] Therefore, as the fourth rotating member 205 rotates, the first oblique pushing block 205 a pushes the second oblique pushing block 205 b to slide, and causes the first moving rod 203 to slide in a direction (first direction) approaching the detected component 3 .

[0338] Therefore, this solution provides a specific implementation method for converting the rotational force of the power receiving device 4 into a driving force on the first moving rod 203, which can make full use of the rotational force of the power receiving device 4, and generate a forced thrust by the first oblique push block 205a squeezing the second oblique push block 205b during rotation, so that the first moving rod 203 can slide in the box body 1, and then push the detected part 3 to slide in the direction close to the detection device 7 (that is, in the forward direction along the second direction) through the connecting rod 204.

[0339] In this embodiment, there are at least two first oblique push blocks 205a evenly distributed on the fourth rotating member 205. A first rotation recess 205d is formed between adjacent first oblique push blocks 205a. The first rotation recess 205d allows the first movable rod 203 to penetrate, allowing the connecting rod 204 to drive the detected portion 3 to slide away from the detection device 7. This generates a detection electronic signal with a time interval between the detected portion 3 and the detection device 7. The electronic signal with different contact times is output based on the length of time between the detected portion 3 and the detection device 7, thereby completing the function of the developer cartridge being recognized by the detection device 7 in the image forming device.

[0340] The detected component 3 is slidably connected to the inner side of the box body 1 away from the power receiving device 4 (i.e., located next to the non-driving side), and can slide in the direction of approaching or moving away from the detection device 7 (i.e., the second direction); specifically, a second sliding groove 102 is provided on the box body 1, and the detected component 3 is slidably connected in the second sliding groove 102; thus, this solution provides a specific implementation method of the sliding connection between the first moving rod 203 and the detected component 3 on the box body 1.

[0341] The connecting rod 204 has one end rotationally connected to the first movable rod 203 and the other end rotationally connected to the detected component 3; driven by the transmission component 2, the first movable rod 203 slides in the direction (first direction) close to the detected component 3, and causes the connecting rod 204 to drive the detected component 3 to slide in the direction close to the detection device 7 (i.e., in the forward direction along the second direction).

[0342] like Figure 68 、 Figure 69 、 Figure 70 As shown, the seventh elastic member 187 is disposed on the housing 1 and connected to the first movable rod 203. It can provide a restoring elastic force for the first movable rod 203. Under the action of the seventh elastic member 187, the first movable rod 203 can slide away from the detected component 3, and the connecting rod 204 can drive the detected component 3 to slide away from the detection device 7. In this embodiment, the seventh elastic member 187 is a spring.

[0343] When the power receiving device 4 continuously outputs rotational power in one direction, the first movable rod 203 of the present scheme can realize reciprocating motion under the action of the seventh elastic member 187 through the first rotating recess 205d or the second rotating recess 205e, so as to be converted into the driving force output by the detected component 3 to the detection device 7 through the connecting rod 204, and then output an electronic signal with a frequency.

[0344] The first movable rod 203 has a mounting groove 203b defined within it, and the housing 1 has a mounting protrusion 203c extending into the mounting groove 203b. One end of the seventh elastic member 187 abuts against the mounting protrusion 203c, while the other end abuts against the mounting groove 203b. The mounting protrusion 203c provides a limit for the sliding movement of the first movable rod 203 and also supports the seventh elastic member 187. This solution provides a specific embodiment of the connection between the seventh elastic member 187 and the first movable rod 203.

[0345] like Figure 65 、 Figure 66 and Figure 67 As shown, in this embodiment, the connecting rod 204 includes: a rod body 204c, a first connecting portion 204a, and a second connecting portion 204b, specifically as follows:

[0346] The first connecting portion 204a has one end pivotally connected to the first movable rod 203 and its other end connected to the rod body 204c. The second connecting portion 204b has one end connected to the rod body 204c and its other end pivotally connected to the detected portion 3. Thus, this solution provides a specific structural configuration of the connecting rod 204, which is simple and easy to manufacture. Specifically, the first connecting portion 204a is hingedly connected to the first movable rod 203, and the second connecting portion 204b is hingedly connected to the detected portion 3. This solution utilizes a hinged structure to connect the connecting rod 204 to the first movable rod 203 and the detected portion 3, resulting in a simple structure that facilitates manufacturing.

[0347] A rotation groove 203a is formed at the end of the first moving rod 203, and the first connecting portion 204a is rotatably connected to the rotation groove 203a. This solution provides a specific location for the first connecting portion 204a to be rotatably connected to the first moving rod 203.

[0348] Working process:

[0349] like Figure 67As shown, the power receiving device 4 transmits rotational power to the fourth rotating member 205 and causes it to rotate. As the fourth rotating member 205 rotates, the first oblique push block 205a applies a forced thrust to the second oblique push block 205b. After being subjected to the forced thrust, the second oblique push block 205b drives the first moving rod 203 to slide in the direction close to the detected component 3 (i.e., the first direction); as the first moving rod 203 slides, the first moving rod 203 compresses the seventh elastic member 187 and causes the seventh elastic member 187 to obtain elastic force, and the connecting rod 204 rotates and drives the detected component 3 to slide in the direction close to the detection device 7 (i.e., forward along the second direction). At this time, the detected component 3 applies pressure to the detection device 7, and the detection device 7 enters the detection state after being pressed;

[0350] like Figure 66 As shown, with the rotation of the fourth rotating member 205, when the second oblique push block 205b on the first moving rod 203 rotates to the first rotating recess 205d, under the action of the seventh elastic member 187, the first moving rod 203 slides rightward along the first direction, and the second oblique push block 205b slides in the first rotating recess 205d, and the connecting rod 204 rotates and drives the detected component 3 to slide in the direction away from the detection device 7 (i.e., backward along the second direction). At this time, the detected component 3 no longer applies pressure to the detection device 7, and the detection device 7 exits the detection state;

[0351] In this embodiment, the detection device 7 can rotate, so the detected component 3 and the detection device 7 always maintain abutment state, but it is not limited to this. The detection device 7 can also be fixed and realize the switching of the detection state by receiving the pressure applied by the detected component 3.

[0352] Example 16

[0353] like Figure 66 and 67 As shown, the difference between the sixteenth embodiment and the fifteenth embodiment is that the transmission assembly 2 further includes a third oblique pushing block 205c in addition to the first oblique pushing block 205a.

[0354] Specifically, the transmission assembly 2 further includes:

[0355] A third inclined push block 205c is disposed on the fourth rotating member 205 and has a third inclined surface 205c1;

[0356] A second rotation recess 205e is formed between the first oblique pushing block 205a and the third oblique pushing block 205c.

[0357] The first oblique push block 205a and the third oblique push block 205c have different circumferences on the fourth rotating member 205, so the lengths of the second rotating recess 205e between the two are also different, thereby being able to output electronic signals with different contact times to facilitate adaptation to different types of developer cartridges.

[0358] Furthermore, the inclination angle of the third inclined surface 205c1 is greater than that of the first inclined surface 205a1 and the second inclined surface 205b1, so that the first moving rod 203 moves faster when driven by the third inclined surface 205c1. Consequently, the detected component 3 also moves faster when it triggers the detection device 7, causing the detection device 7 to detect that the detected component 3 is triggering the detection device 7 at a faster speed and generate an electrical signal.

[0359] In other embodiments, by changing the inclination angles of the first, second, and third inclined surfaces 205a1, 205b1, and 205c1, the movement speed of the first moving rod 203 when driven by the first, second, and third inclined surfaces 205a1, 205b1, and 205c1 can be varied. By setting different inclination angles for the first, second, and third inclined surfaces 205a1, 205b1, and 205c1, the first moving rod 203 can have multiple movement speeds. By setting a ratio between the inclination angles of the first, second, and third inclined surfaces 205a1, 205b1, and 205c1, the ratio between the different movement speeds of the first moving rod 209 can be set.

[0360] Beneficial effects

[0361] Since the existing detected component 3 is driven by the power receiving device 4, the detection device 7 and the detected component 3 are generally arranged beside the power receiving device 4; however, this solution provides a specific implementation method in which the detected component 3 and the detection device 7 are located on the box body 1 away from the power receiving device 4 through the combination of the first moving rod 203, the transmission component 2 and the connecting rod 204, and the detected component 3 and the detection device 7 of this solution are in a conflicting connection, and it does not require a complicated operation or structure to release the connection between the detected component 3 and the detection device 7, so it can solve the problem of avoiding inconvenient operation when installing or removing it into the image forming device, and it can also effectively solve the problem of the developing box being difficult to identify due to the complicated connection relationship between the detected component 3 and the detection device 7, so as to ensure the normal operation of the developing box.

[0362] Example 17

[0363] like Figures 98 to 101As shown, this embodiment differs from the fifteenth embodiment in that the first movable rod 209 is cylindrical. In this embodiment, the mounting groove 203b and the rotation groove 203a are omitted. The first slide 101 includes a first section 101a and a second section 101b that are connected in the first direction. The first section 101a is closer to the transmission assembly than the second section 101b in the first direction. The second section 101b is provided with a positioning portion 101b1. In this embodiment, there are two positioning portions 101b1. Each positioning portion 101b1 has a positioning hole whose shape and size match the cross-section of the first movable rod 209. The first movable rod 209 is slidably mounted within the positioning hole. A driven member 209c is fixedly mounted on the end of the first movable rod 209 that is closest to the transmission assembly in the first direction. The driven member 209c can be fixed to the first movable rod 209 by means of a threaded connection, a screw connection, a snap-fit ​​connection, or the like. A driven protrusion 209c1, projecting in the first direction, is integrally formed on one end of the driven member 209c, proximal to the transmission assembly. This driven protrusion 209c1 is integrally formed with a circular arc surface, which ensures smoother contact between the driven protrusion 209c1 and the first and third oblique thrust blocks 205a, 205c. The driven member 209c is slidably mounted within the first section 101a. The first section 101a is larger in the second direction than the second section 101b. The seventh elastic member 187 is sleeved over the portion of the first movable rod 209 located within the first section 101a. One end of the seventh elastic member 187 abuts the driving member 209c, while the other end abuts the positioning portion 101b1.

[0364] A transmission member 209a is fixedly mounted on the end of the first moving rod 209 away from the transmission assembly in the first direction. The transmission member 209a is fixedly mounted on the first moving rod 209 by threaded connection, screw connection, snap connection, etc. A first pin 209b extending upward along the third direction is integrally formed on the transmission member 209a.

[0365] In this embodiment, the connecting rod 204 is eliminated. The detected portion 3 includes a first portion 371, a second portion 372, and a third portion 373. The first portion 371 is arranged parallel to the second direction. A pivot slot 3711 is integrally formed at the end of the first portion 371 in the second direction, which is closer to the first movable rod 209. The pivot slot 3711 opens rearwardly in the second direction, and the first pin 209b is rotatably and slidably inserted into the pivot slot 3711. A second pin 3712 is integrally formed at the end of the first portion 371 in the second direction, which is further away from the first movable rod 209, and which extends in the third direction. A pivot seat 17 is integrally formed on the housing 1 and fixed thereto. The second pin 3712 is rotatably connected to the pivot seat 17. The second portion 372 is integrally connected to the end of the first portion 371 in the second direction, which is further away from the first movable rod 209. The second portion 372 forms a 90-degree angle with the first portion 371. The end of the second portion 372 away from the first portion 371 in the first direction is integrally connected to the third portion 373. The end of the third portion 373 away from the second portion 372 in the second direction is the detected end 32. The third portion 373 and the second portion 372 form a 70-degree angle.

[0366] The difference between the working process of this embodiment and that of the fifteenth embodiment is that when the first moving rod 209 is pushed by the first oblique pushing block 205a or the third oblique pushing block 205c, the first oblique pushing block 205a or the third oblique pushing block 205c acts on the arc surface of the driven protrusion 209c1, making the pushing process of the first moving rod 209 smoother. After the first moving rod 209 moves along the first direction, the seventh elastic member 187 is compressed, and the transmission member 209a on the first moving rod 209 pushes the pivot slot 3711 along the first direction via the first pin 209b, causing the first portion 371 to swing counterclockwise around the second pin 3712 (to rotate counterclockwise). Figure 100 The viewing angle is the observation viewing angle). As a result, the detected end 32 swings counterclockwise, thereby pushing the detection device 7 in the image forming device.

[0367] By adopting the design of this embodiment, the assembly of the first moving rod 209 and the transmission member 209a is simpler, the structure is simpler, and the transmission is more stable.

[0368] Embodiment 18

[0369] Such as 102 to Figure 104As shown, the difference between this embodiment and Example 17 is that in this embodiment, the fourth rotating member 205 is further provided with a fourth oblique pushing block 205f and a fifth oblique pushing block 205g. The fourth oblique pushing block 205f and the fifth oblique pushing block 205g are respectively provided with a fourth inclined surface 205f1 and a fifth inclined surface 205g1. The first oblique pushing block 205a, the third oblique pushing block 205c, the fourth oblique pushing block 205f, and the fifth oblique pushing block 205g are arranged in sequence along the circumferential direction on an end surface of the fourth rotating member 205 close to the box body. The angle θ1 between the first oblique surface 205a1 and the end surface of the fourth rotating member 205 is 50°. The angle θ2 between the third oblique surface 205c1, the fourth oblique surface 205f1, and the fifth oblique surface 205g1 and the end surface of the fourth rotating member 205 is 35°.

[0370] In other embodiments of the present technical solution, the angle θ1 between the first inclined surface 205a1 and the end face of the fourth rotating member 205 is between 50° and 70°, and the angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, the fifth inclined surface 205g1 and the end face of the fourth rotating member 205 is between 35° and 50°, which can ensure the stability and smoothness of power transmission without affecting the implementation of the technical solution.

[0371] When the first inclined surface 205a1 drives the first moving rod 209, the first moving rod 209 moves at a first speed in the first direction. When the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 drive the first moving rod 209, the first moving rod 209 moves at a speed V2 in the first direction. Because the angle θ1 between the first inclined surface 205a1 and the end surface of the fourth rotating member 205 is greater than the angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 and the end surface of the fourth rotating member 205, and the rotational speed of the fourth rotating member 205 is fixed, V1 is greater than V2. Consequently, when the fourth rotating member 205 rotates, the detected end 32 can contact the detection device within the image forming device once at a speed V1 and then three times at a speed V2. Therefore, the image forming apparatus can identify the developing cartridge not only based on the number of times the detecting device 7 is touched, but also based on the speed at which the detecting device 7 is touched.

[0372] Compared to detection based solely on the number of touches, combining touch speed with the number of touches increases the dimension of detectable information. The image forming device can identify a wider range of developer cartridge models based on the combination of touch speed and number of touches, improving versatility. Furthermore, transmission via the fourth rotating member 205 and the inclined surface offers a simple structure, stable transmission, low manufacturing difficulty, and low cost, making it suitable for mass production.

[0373] Example 19

[0374] like Figures 102 to 104 As shown, the difference between this embodiment and the eighteenth embodiment is that the angle θ1 between the first inclined surface 205a1 and the end surface of the fourth rotating member 205 is 60°. The angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 and the end surface of the fourth rotating member 205 is 40°. In this embodiment, the angles between the first inclined surface 205a1, the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 and the end surface of the fourth rotating member 205 are changed. This changes the values ​​of V1 and V2, allowing the detection device 7 of the image forming apparatus to detect different models of developer cartridges when touched at different speeds, thereby improving applicability, ensuring transmission stability, and preventing jamming due to excessive angles.

[0375] Example 20

[0376] like Figures 102 to 104 As shown, this embodiment differs from the eighteenth embodiment in that the angle θ1 between the first inclined surface 205a1 and the end surface of the fourth rotating member 205 is 70°. The angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 and the end surface of the fourth rotating member 205 is 50°. In this embodiment, the angles V1 and V2 are changed, allowing the detection device 7 of the image forming apparatus to detect different models of developer cartridges when touched at different speeds, thereby improving applicability. The angle is also increased to its maximum value, ensuring stable transmission while broadening the range of selectable angles and increasing the number of detectable models. This improves applicability and versatility.

[0377] Example 21

[0378] like Figures 18 to 28As shown, the difference between this embodiment and the fifteenth embodiment is that a first positioning protrusion 205a2 and a second positioning protrusion 205a3 are integrally formed on the surface of the first oblique pushing block 205a close to the box body 1. The first positioning protrusion 205a2 and the second positioning protrusion 205a3 are arranged along the rotation direction of the fourth rotating member 205, with a gap between the first positioning protrusion 205a2 and the second positioning protrusion 205a3. In the rotation direction of the fourth rotating member 205, the second positioning protrusion 205a3 is located upstream of the first positioning protrusion 205a2. The first positioning protrusion 205a2 and the second positioning protrusion 205a3 have arc surfaces close to the box body 1, so that the contact between the first positioning protrusion 205a2 and the second positioning protrusion 205a3 and the driven protrusion 209c1 is smoother, and when the first positioning protrusion 205a2 and the second positioning protrusion 205a3 make circular motion together with the fourth rotating member 205, the first positioning protrusion 205a2 and the second positioning protrusion 205a2 can apply a force toward the left direction to the driven protrusion 209c1.

[0379] In this embodiment, a partial gear 205h is coaxially integrally formed on the fourth rotating member 205, and the fourth rotating member 205 receives power transmitted by the power receiving device 4 through gear transmission. In other embodiments, transmission can also be performed through non-gear methods such as friction transmission and belt transmission.

[0380] A first protective cover 111 is also mounted on the first end 11 of the housing 1. The first protective cover 111 is used to protect the transmission device and the power receiving device 4. The first protective cover 111 is removably secured to the housing 1 by screws or snaps. A protective cover opening 351 is defined in the first protective cover 111, through which the incomplete gear 205h is exposed. A first scale 111a and a second scale 111b are integrally formed on the first protective cover 111 at the protective cover opening 351. An identification portion 205h1 is integrally formed on the incomplete gear 205h. When the identification portion 205h1 aligns with the first scale 111a, the incomplete gear 205h disengages and stops receiving power, and the fourth rotating member 205 stops rotating. When the identification portion 205h1 aligns with the second scale 111b, the incomplete gear 205h is engaged, and the fourth rotating member 205 can be driven by the power transmitted by the power receiving device 4.

[0381] Next, the specific operation of the developer cartridge in this embodiment will be described. The portions identical to those in Embodiments 3 and 1 will be omitted. As the fourth rotating member 205 rotates in the rotational direction J, the first positioning protrusion 205a2 rotates to a position where it contacts the driven protrusion 209c1, exerting a leftward force on the driven protrusion 209c1. This causes the first movable rod 209 to move leftward, and the driven protrusion 209c1 to clear the first positioning protrusion 205a2. After the first positioning protrusion 205a2 passes the driven protrusion 209c1, the first movable rod 209, under the action of the seventh elastic member 187, moves rightward and returns to its original position. At this point, the driven protrusion 209c1 is located between the first positioning protrusion 205a2 and the second positioning protrusion 205a3. When the marking portion 205h1 aligns with the first scale mark 111a, the incomplete gear 205h disengages and stops receiving power, causing the fourth rotating member 205 to stop rotating. Since the driven protrusion 209c1 is located between the first positioning protrusion 205a2 and the second positioning protrusion 205a3, and the driven protrusion 209c1 can only move along the left and right directions (i.e., the first direction), when the fourth rotating member 205 moves due to external factors such as the shaking of the box body 1, the first positioning protrusion 205a2 and the second positioning protrusion 205a3 are against the driven protrusion 209c1, and the first positioning protrusion 205a2 and the second positioning protrusion 205a3 need to overcome the elastic force of the seventh elastic member 187 before they can continue to rotate, thereby preventing the fourth rotating member 205 from producing unexpected movement, and achieving the positioning effect of the fourth rotating member 205 when the incomplete gear 205h is disengaged, preventing the fourth rotating member 205 from producing unexpected movement and causing the incomplete gear 205h to be misengaged, thereby causing the detected end to produce unexpected movement, and then causing the detected end to mistouch the detection device in the image forming device.

[0382] When the fourth rotating member 205 needs to be reset, the user only needs to manually move the fourth rotating member 205 along the rotation direction J of the fourth rotating member 205, so that the second positioning protrusion 205a3 overcomes the elastic force of the elastic member and pushes the driven end, thereby causing the fourth rotating member 205 to rotate to a position where the identification portion 205h1 is aligned with the second scale 111b. At this time, the incomplete gear 205h enters the meshing state again and can receive the power transmitted by the power receiving device 4 and rotate.

[0383] Example 22

[0384] like Figures 71 to 96 As shown, this embodiment discloses a developing device, which can be detachably mounted on a drum assembly in an image forming device. The developing device includes a box body 1, a developing assembly, a transmission assembly 2, an identification assembly, a detected assembly 3, a power supply assembly, a first protective cover 111 and a second protective cover 121.

The box body 1 is provided with a handle 141 located at the fourth end 14. A first protective cover 111 is removably fixed to the first end 11 of the box body 1 by screws or snaps. The first protective cover 111 is used to protect the transmission assembly 2. A second protective cover 121 is removably mounted to the second end 12 of the box body 1 by screws or snaps. The second protective cover 121 is used to protect the detected assembly 3.

[0386] The developing assembly includes a developing roller 131, a powder feed roller, and a stirring frame. These rollers are rotatably mounted within the receiving chamber between the first end 11 and the second end 12. The rotational axes of the developing roller 131, the powder feed roller, and the stirring frame extend along a first direction. The developing roller 131 is positioned at the powder outlet. The powder feed roller is positioned adjacent to the developing roller 131. The powder feed roller is closer to the fourth end 14 of the cartridge body 1 than the developing roller 131. The stirring frame is used to stir the developer within the receiving chamber to provide friction and prevent clumping.

[0387] The transmission assembly is disposed at the first end 11 and includes a power receiving device 4 rotatably mounted on the first end 11 of the housing 1. The rotation axis of the power receiving device 4 is parallel to the first direction. The power receiving device 4 comprises a coaxial, integrally formed drive gear and a power receiving portion. The drive gear is located closer to the first end 11 of the housing 1 than the power receiving portion in the first direction. The power receiving portion is configured to couple with a power output shaft on the image forming device to receive power output from the image forming device.

[0388] The transmission assembly also includes a developing gear 43, a powder feeding gear 44, a stirring gear set 24, and a first idler gear 471. The developing gear 43 is coaxially fixedly mounted on the end of the developing roller 131 near the first end 11 of the box body 1. The powder feeding gear 44 is coaxially fixedly mounted on the end of the powder feeding roller near the first end 11 of the box body 1. The stirring gear set 24 is coaxially fixedly mounted on the end of the stirring frame near the first end 11 of the box body 1. A support column is integrally formed on the first end 11 of the box body 1 along the first direction. The first idler gear 471 is rotatably mounted on the support column. The rotation axis of the first idler gear 471 is parallel to the first direction. The first idler gear 471 includes a large-diameter first idler gear and a small-diameter first idler gear. In the first direction, the large-diameter first idler gear is closer to the first end 11 of the box body 1 than the small-diameter first idler gear.

[0389] The developing gear 43, the powder feeding gear 44, and the first large-diameter idler gear are all meshed with the driving gear. The stirring gear set 24 is meshed with the first small-diameter idler gear. The meshing can be direct or indirect.

[0390] The rotation axis of the power receiving device 4 is closer to the fifth end 15 and the fourth end 14 of the box body 1 than the rotation axis of the developing roller 131, and the rotation axis of the power receiving device 4 is closer to the third end 13 of the box body 1 than the rotation axis of the stirring frame.

[0391] The detected component 3 includes a first slider 207a, a second slider 207b, a fifth rotating member 206, a sixth rotating member 208a, and a groove wheel 48. The first slider 207a is the detected member. The groove wheel 48 is coaxially fixedly mounted on one end of the stirring frame located at the second end 12 of the box body 1. The fifth rotating member 206 is rotatably mounted on the second end 12 of the box body 1, and the rotation axis of the fifth rotating member 206 is parallel to the first direction. A plurality of cylindrical pins 298 distributed along the circumference of the fifth rotating member 206 are integrally formed on a surface of the fifth rotating member 206 close to the second end 12 of the box body 1 in the first direction. In this embodiment, the number of cylindrical pins 298 is twenty-five. The spacing between adjacent cylindrical pins 298 is equal. The cylindrical pins 298 cooperate with the groove wheel 48. A fifth protrusion 381 and a sixth protrusion 382 are integrally formed on a surface of the fifth rotating member 206 that is distal from the second end 12 of the housing 1 in the first direction. The surfaces of the fifth protrusion 381 and the sixth protrusion 382 that are radially distal from the rotation axis of the fifth rotating member 206 serve as a fourth contact surface and a fifth contact surface, respectively. Both the fourth and fifth contact surfaces are arcuate surfaces, and the radii of the fourth and fifth contact surfaces (i.e., the distances from the surfaces of the fourth and fifth contact surfaces radially distal from the axis of the fifth rotating member 206 to the axis of the fifth rotating member 206) are equal. A seventh protrusion 383 is integrally formed on the circumferential surface of the fifth rotating member 206, protruding radially beyond the circumferential surface of the fifth rotating member 206. The distance from the surface of the seventh protrusion 383 radially distal from the rotation axis of the fifth rotating member 206 to the axis of the fifth rotating member 206 is greater than the radii of the fourth and fifth contact surfaces. The central angle subtended by the fifth protrusion 381 is greater than the central angle subtended by the sixth protrusion 382 .

[0392] A guide rail 122 is integrally formed on the second protective cover 121 along the second direction. Both the first slider 207a and the second slider 207b are slidably mounted within the guide rail 122 along the second direction. The first slider 207a is closer to the developing roller 131 in the second direction than the second slider 207b. The end of the first slider 207a that is closer to the developing roller 131 in the second direction serves as the detection end 32. A support seat extending along the first direction is integrally formed within the guide rail 122. The first slider 207a has a mounting recess 207c defined therein, into which the support seat extends. An eighth elastic member 188 is mounted between the support seat and the sidewalls of the mounting recess 207c. The eighth elastic member 188 is used to reposition the first slider 207a. A second lever 207a1 is integrally formed on the first slider 207a, partially located within the motion paths of the fifth and sixth protrusions 381 and 382.

[0393] The end of the slide rail in the second direction away from the developing roller 131 is integrally formed with a support plate 121a ( Figure 84 (shown), the end of the slide rail close to the developing roller 131 in the second direction is an opening for the detected end 32 to extend out. The support seat is located on the slide rail between the support plate 121a and the opening in the second direction. A mounting groove is integrally formed on the second slider 207b along the second direction, and the end of the mounting groove close to the support plate 121a is not closed. A ninth elastic member 189 is installed in the mounting groove, and one end of the ninth elastic member 189 is abutted against the end of the mounting groove away from the support plate 121a in the second direction, and the other end of the ninth elastic member 189 is abutted against the support plate 121a. The elastic coefficient of the ninth elastic member 189 is greater than that of the eighth elastic member 188. A first limiting opening 121b is provided on the second slider 207b, and the first limiting opening 121b is located on the lower side wall of the mounting groove. A second limiting opening 121c is provided in the slide rail. The second limiting opening 121c is located in the slide rail between the support seat and the support plate 121a. A first limiting protrusion 207b1 is integrally formed on one end of the second sliding block 207b close to the support plate 121a, and a second limiting protrusion 207b2 matching the first limiting protrusion is integrally formed on the sliding groove.

[0394] A sixth rotating member 208a is rotatably mounted on the second protective cover 121. The rotation axis of the sixth rotating member 208a is parallel to the first direction. The sixth rotating member 208a is located below the second limiting opening. The sixth rotating member 208a is cylindrical, and a third limiting protrusion 207b3 is integrally formed on the circumference of the sixth rotating member 208a. A driven protrusion 209c1 is also integrally formed on the circumference of the sixth rotating member 208a, and the driven protrusion 209c1 is located within the motion path of the seventh protrusion 383. A reset arm 331 is integrally formed on the circumference of the sixth rotating member 208a. A stopper 33 is integrally formed on the end of the reset arm 331 away from the sixth rotating member 208a. A reset opening is defined in the second protective cover 121 for the reset arm 331 to extend. The reset opening is smaller than the stopper 33, preventing the stopper 33 from passing through the reset opening.

[0395] The sixth rotating member 208a, the second sliding block 207b, and the ninth elastic member 189 constitute a speed shift assembly.

[0396] The first slider 207a has a third state and a fourth state.

[0397] In the third state, the detected end 32 of the first slider 207 a extends out of the sliding groove, and the eighth elastic member 188 is compressed.

[0398] In the fourth state, the detected end 32 of the first slider 207 a is farther away from the developing roller 131 than in the third state, and the eighth elastic member 188 does not undergo elastic deformation.

[0399] The power supply assembly includes a conductive member located at the second end 12 of the housing 1. The conductive member has an electrical receiving surface 51. The conductive member also has a first power supply terminal and a second power supply terminal. The first power supply terminal is electrically connected to the end of the developing roller 131 near the second end 12 of the housing 1, and the second power supply terminal is electrically connected to the end of the powder feed roller near the second end 12 of the housing 1. The electrical receiving surface 51 is configured to contact the power supply portion of the image forming device to receive electrical energy output by the image forming device and transmit the electrical energy to the developing roller 131 and the powder feed roller to form a bias voltage between the developing roller 131 and the powder feed roller. In the second direction, the electrical receiving surface 51 is located between the rotation axis of the stirring frame and the developing roller 131.

[0400] The identification component includes a storage medium and an electrical contact surface 5. The storage medium is used to store data, and the electrical contact surface 5 is used to contact and electrically connect with the identification contacts in the image forming device. The storage medium is fixedly mounted on the first protective cover 111, and the electrical contact surface 5 is fixedly mounted on the storage medium and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end surface of the storage medium. There is an intersection between the third direction and the electrical contact surface 5. The electrical contact surface 5 is located between the rotation axis of the developing roller 131 and the rotation axis of the stirring frame 240 in the second direction. In the second direction, the distance between the electrical contact surface 5 and the rotation axis of the driving portion is smaller than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame.

[0401] The following describes the operating process of the developing device disclosed in this embodiment. The developing device is installed on the drum assembly within the image forming device. The image forming device's power output shaft is connected to the power receiving unit. The identification contacts within the image forming device contact the electrical contact surface 5 and read the information stored in the storage medium to identify the model, capacity, lifespan, and other information of the developing device.

[0402] The developing device disclosed in this embodiment has a factory-set state. In this factory-set state, the detected component 3 is in the third state, the second lever 207a1 contacts and is restrained by the fourth contact surface, causing the first slider 207a to remain in the third state and unable to return to its original position under the action of the eighth elastic member 188. Simultaneously, the first limiting opening 121b and the second limiting opening 121c are aligned, the ninth elastic member 189 is compressed, and the third limiting protrusion 207b3 is inserted into the first limiting opening 121b and the second limiting opening 121c. The third limiting protrusion 207b3 abuts against the sidewall of the second limiting opening 121c in the second direction away from the support plate 121a. As a result, the second slider 207b is trapped and restrained by the third limiting protrusion 207b3, preventing the release of the elastic potential energy of the ninth elastic member 189.

[0403] When the developing device is installed on the drum assembly in the image forming device, the detected end 32 on the developing device in the initial state is in a state of extending out of the slide rail. Therefore, the detected end 32 will cause the first push on the detection part in the image forming device during the process of the developing device being installed into the drum assembly, causing the detection part to generate an electrical signal, thereby allowing the image forming device to detect that the developing device is installed.

[0404] When the image forming apparatus receives a print instruction, the image forming apparatus starts outputting power to the power receiving portion so that the power receiving portion rotates around the power receiving portion. Figure 75 The clockwise rotation (the direction of rotation in this paragraph is Figure 75The drive gear rotates along with the power receiving unit, driving the developing gear 43, the powder feeding gear 44, and the large-diameter first idler gear to rotate counterclockwise. The small-diameter first idler gear rotates counterclockwise along with the large-diameter first idler gear. The small-diameter first idler gear drives the stirring gear set 24 to rotate clockwise. This causes the developing roller 131, the powder feeding roller, and the stirring frame to start operating.

[0405] At the same time, the stirring frame drives the groove wheel 48 around Figure 73 The counterclockwise rotation (the following description of the rotation direction is based on Figure 73 As the observation angle is taken as a reference), since the sheave 48 cooperates with the cylindrical pin 298, the sheave 48 drives the fifth rotating member 206 to rotate through the cylindrical pin 298.

[0406] As the fifth rotating member 206 rotates, when the fifth protrusion 381 disengages from the second lever 207a1, the fourth contact surface no longer abuts against the second lever 207a1, thereby losing the limiting effect on the second lever 207a1. Under the elastic force of the eighth elastic member 188, the first slider 207a moves to the fourth state, and at this time, the detected end 32 no longer pushes the detection member.

[0407] Then, as the fifth rotating member 206 rotates, the sixth protrusion 382 contacts the second lever 207a1, and the sixth protrusion 382 pushes the second lever 207a1 to move along the second direction toward the direction close to the developing roller 131, so that the first slider 207a moves to the third state again, and the detection end 32 pushes the detection member for the second time.

[0408] Then, as the fifth rotating member 206 rotates, the sixth protrusion 382 is no longer in contact with the second lever 207a1. Under the elastic force of the eighth elastic member 188, the first slider 207a moves to the fourth state. At this time, the detected end 32 no longer pushes the detection member.

[0409] Then, as the fifth rotating member 206 rotates, the seventh protrusion 383 shifts the driven protrusion 209c1, thereby driving the sixth rotating member 208a to rotate counterclockwise. This causes the sixth rotating member 208a to rotate the third limiting protrusion 207b3 counterclockwise, causing the third limiting protrusion 207b3 to move out of the first limiting opening 121b and the second limiting opening 121c. The second slider 207b is no longer restrained by the third limiting protrusion 207b3, and the elastic potential energy accumulated in the ninth elastic member 189 is released. Under the elastic force of the ninth elastic member 189, the second slider 207b moves along the slide rail to a position where the first limiting protrusion and the second limiting protrusion abut against each other. During the movement of the second slider 207b, the second slider 207b strikes the first slider 207a, causing the first slider 207a to move again to the third state, and the detection end 32 pushes the detection member for the third time. At the same time, because the elastic coefficient of the ninth elastic member 189 is greater than that of the eighth elastic member 188, the elastic coefficient of the ninth elastic member 189 is greater than that of the eighth elastic member 188. Therefore, the elastic force of the eighth elastic member 188 cannot overcome the elastic force of the ninth elastic member 189, preventing the first slider 207a from returning to its original position. Consequently, the first slider 207a remains in the third state, and the detection end 32 continues to push the detection member. Simultaneously, the fifth protrusion 381 and the sixth protrusion 382 can no longer actuate the second lever 207a1, thereby completing the detection process.

[0410] Furthermore, by selecting a ninth elastic member 189 with a relatively high elastic coefficient, the movement speed of the first slider 207a after being struck by the second slider 207b is a second speed, which is greater than the first speed generated when the first slider 207a is pushed by the fifth protrusion 381 and the sixth protrusion 382. Alternatively, the ninth elastic member 189 with a relatively low elastic coefficient can be selected to make the second speed less than the first speed. With this design, the first slider 207a can have different movement speeds, and the image forming device can detect changes in the movement speed of the first slider 207a, thereby detecting information from the developing device.

[0411] Through the above process, the image forming device can detect the number of times the detection end 32 pushes the detection member, the duration of the pushing, the interval duration, the pushing speed and other information. Different arrangements and combinations of the above information correspond to different developing device information (such as different models, different capacities, newness, etc.).

[0412] As the sixth rotating member 208a rotates, it also drives the reset arm to perform a circular motion, causing the reset arm to drive the block 33 toward the inside of the second protective cover 121. When the detected component 3 needs to be reset, the sixth rotating member 208a only needs to be rotated to its initial position. Then, the second slider 207b is pressed into the slide rail to align the first limit opening 121b and the second limit opening 121c. The block 33 is then pulled, causing the reset arm to rotate the sixth rotating member 208a. The sixth rotating member 208a drives the third limit protrusion 207b3 to reengage the first limit opening 121b and the second limit opening 121c, completing the reset of the first slider 207a and the second slider 207b. Preferably, the reset arm can be made of an elastic material. When the sixth rotating member 208a is rotated by the seventh protrusion 383, the reset arm undergoes elastic deformation, accumulating elastic potential energy. When the first limiting opening 121b is aligned with the second limiting opening 121c, the sixth rotating member 208a rotates automatically under the elastic action of the reset arm, so that the third limiting protrusion 207b3 is automatically inserted into the first limiting opening 121b and the second limiting opening 121c, completing the reset.

[0413] Because the central angle subtended by the fifth protrusion 381 is larger than the central angle subtended by the sixth protrusion 382, ​​when the second lever 207a1 contacts the fifth protrusion 381, the first slider 207a remains in the third state for a longer period than when the second lever 207a1 contacts the sixth protrusion 382. The time the first slider 207a remains in the third state can be varied by changing the central angle subtended by the fifth and sixth protrusions 381, 382. The number of times the first slider 207a enters the third state can be increased by increasing the number of protrusions. The order of the fifth, sixth, and seventh protrusions 381, 382, ​​and 383 can also be adjusted based on actual needs.

[0414] The above structure can greatly reduce the difficulty of resetting the detected component 3, improve the convenience of user use and the convenience of factory debugging.

[0415] Example 23

[0416] like Figures 90 to 92 As shown, the difference between this embodiment and Example 22 is that the speed change assembly in this embodiment eliminates the sixth rotating member 208a, the second slider 207b, and the ninth elastic member 189 from Example 22. Instead, the speed change assembly in this embodiment includes a tenth elastic member. The tenth elastic member is a torsion spring. The tenth elastic member includes a main body 191a formed by winding a metal wire along a ring. A fixed arm 191b is integrally formed at the left end of the main body 191a, and an action portion 191c is integrally formed at the right end of the main body 191a. The action portion 191c includes a force-bearing portion 191d and a force-applying portion 191e, with the force-applying portion 191e being longer than the force-bearing portion 191d.

[0417] The second protective cover 121 is integrally formed with a first support portion 111d, a second support portion 111e, a first limiting portion 111f, and a second limiting portion 111g. The first support portion 111d and the second support portion 111e protrude rightward from the right surface of the first protective cover 111. The first support portion 111d, the second support portion 111e, and the second limiting portion 111g are arranged sequentially along the same circumference, with a gap between the first support portion 111d and the second support portion 111e. The first limiting portion 111f is groove-shaped, and the fixed arm 191b extends into and is restrained by the first limiting portion 111f. The second limiting portion 111g is an arc-shaped groove, and the portion of the main body 191a closest to the second protective cover 121 is engaged with the second limiting portion 111g. The dimensions of the first support portion 111d and the second support portion 111e in the first direction are larger than the dimensions of the main body 191a in the first direction when it is not elastically deformed. A rightward-protruding positioning post is integrally formed on the second protective cover 121 within the area bounded by the first support portion 111d, the second support portion 111e, and the second stopper 111g. The main body 191a is sleeved onto the post. In the factory default setting, the force-applying portion 191e abuts the right end of the first support portion 111d, while the force-receiving portion 191d abuts the right end of the second support portion 111e. Furthermore, because the second stopper 111g holds the main body 191a in place near the second protective cover 121, the main body 191a is in a stretched state.

[0418] like Figure 90 As shown, in this embodiment, the seventh protrusion 383 protrudes leftward from the left end surface of the fifth rotating member 206 along the axial direction of the fifth rotating member 206. The size of the seventh protrusion 383 in the first direction is larger than the size of the fifth protrusion 381 and the sixth protrusion 382 in the first direction. That is, the left end of the seventh protrusion 383 is farther from the box body 1 than the left ends of the fifth protrusion 381 and the sixth protrusion 382. As a result, only the seventh protrusion 383 can contact the force-bearing portion 191d, while the fifth protrusion 381 and the sixth protrusion 382 cannot contact the force-bearing portion 191d. In this embodiment, the radius of the surface of the seventh protrusion 383 radially away from the rotation axis of the fifth rotating member 206 is equal to the radius of the fourth contact surface and the fifth contact surface.

[0419] The specific working process of this embodiment is different from that of the twenty-second embodiment in that as the fifth rotating member 206 rotates, the seventh protrusion 383 pushes the force-bearing portion 191d, causing the main body 191a to twist, thereby causing the force-bearing portion 191d to swing counterclockwise around the main body 191a ( Figure 91 The force-applying portion 191e is then driven by the force-receiving portion 191d to swing counterclockwise around the main body 191a ( Figure 91Since the force-applying portion 191e is longer than the force-receiving portion 191d, the linear velocity of the end portion of the force-receiving portion 191d during its swinging is less than the linear velocity of the force-applying portion 191e during its swinging. Moreover, since the force-receiving portion 191d is driven to move by the seventh protrusion 383, the linear velocity of the force-receiving portion 191d is equal to the linear velocity of the seventh protrusion 383. Therefore, the linear velocity of the force-applying portion 191e is greater than the linear velocity of the seventh protrusion 383. During the counterclockwise swinging of the force-applying portion 191e, the second lever 207a1 is pushed forward ( Figure 91 The second lever 207a1 moves forward at a second speed, and drives the first slider 207a to push the detection member in the image forming device at the second speed.

[0420] As the force-bearing portion 191d and the force-applying portion 191e swing, when the force-applying portion 191e swings to a position where it no longer abuts the first support portion 111d, the force-bearing portion 191d also swings to a position where it no longer abuts the second support portion 111e. At this time, the main body 191a begins to shrink. Under the action of the elastic force of the main body 191a, the force-bearing portion 191d and the force-applying portion 191e are pulled to the left. Since the force-applying portion 191e and the force-bearing portion 191d are driven by the seventh protrusion 383 to swing, the torsion spring is also twisted in the circumferential direction and elastically deformed. At the same time, since the fixed arm 191b is limited by the second limiting portion 111g, the elastic deformation of the torsion spring in the circumferential direction cannot be restored, so that the force-applying portion 191e and the force-bearing portion 191d are blocked by the side walls of the first support portion 111d and the second support portion 111e and cannot be reset. The force-applying portion 191e maintains contact with the second lever 207a1 as it is pulled to the left by the main body 191a, thereby maintaining the first slider 207a in this position. Because the elastic force of the eighth elastic member 188 cannot overcome the elastic force of the torsion spring 190, the first slider 207a cannot return to its original position.

[0421] When the speed shift assembly 208 in this embodiment needs to be reset, it is only necessary to pull the force-bearing part 191d and the force-applying part 191e to the right, and place the force-applying part 191e on the first support part 111d to abut against the first support part 111d, and place the force-bearing part 191d on the second support part 111e to abut against the second support part 111e to complete the reset.

[0422] Example 24

[0423] like Figures 93 to 97As shown, the difference between this embodiment and Example 23 is that the acting portion and the tenth elastic member in this embodiment are separate structures. In this embodiment, the acting portion is a rocker arm, which includes a pivot portion 191c1, a first arm 191c2, and a second arm 191c3. The pivot portion 191c1 is cylindrical in shape, with the first arm 191c2 integrally formed and fixedly connected to the circumference of the pivot portion 191c1, and the second arm 191c3 integrally formed and fixedly connected to the right end surface of the pivot portion 191c1. The pivot portion 191c1 is rotatably mounted on the positioning post. The distance from the end of the first arm 191c2, which is distal to the rotation axis of the pivot portion 191c1, to the rotation axis of the pivot portion 191c1 is greater than the distance from the end of the second arm 191c3, which is distal to the rotation axis of the pivot portion 191c1, to the rotation axis of the pivot portion 191c1.

[0424] A fourth limiting protrusion 191c1a is integrally formed on the circumferential surface of the pivot portion 191c1. A limiting groove 191f is integrally formed on the right end surface of the second protective cover 121. The fourth limiting protrusion 191c1a is slidably mounted within the limiting groove 191f, which is used to limit the displacement of the swing arm in the first direction. A forward-extending positioning groove 191g is integrally formed at the front end of the groove and is connected to the first protective cover 111.

[0425] A locking protrusion 191c2a is integrally formed on the first arm 191c2, and the locking protrusion 191c2a protrudes forward from the side surface of the first arm 191c2. A surface of the locking protrusion 191c2a that is radially away from the pivot portion 191c1 is a locking surface.

[0426] like Figure 95 As shown, the tenth elastic member is located between the pivot portion 191c1 and the right surface of the second protective cover 121 in the axial direction of the pivot portion 191c1. The main body 191a of the tenth elastic member is sleeved on the positioning shaft, and the fixed arm 191b is engaged with the positioning groove 191g. In this embodiment, the right end of the tenth elastic member 191 is a reset arm 191h. The reset arm 191h abuts against the surface of the swing arm close to the developing roller 131.

[0427] Next, the specific working process of this embodiment is described, wherein the description of the rotation direction is based on Figure 94The difference between the working process of this embodiment and the embodiment is that, as the fifth rotating member 206 rotates, the seventh protrusion 383 contacts the end of the second arm 191c3 that is radially away from the rotation axis of the pivot portion 191c1, so that the second arm 191c3 is pushed by the seventh protrusion 383 to swing counterclockwise, the second arm 191c3 drives the pivot portion 191c1 to rotate counterclockwise, the pivot portion 191c1 drives the first arm 191c2 to swing counterclockwise, and the first arm 191c2 swings counterclockwise. During the swinging process, the side surface of the first arm 191c2 contacts the second lever 207a1 and pushes the second lever 207a1 forward. The contact position between the first arm 191c2 and the second lever 207a1 moves as the first arm 191c2 swings. However, the distance between the contact position between the first arm 191c2 and the second lever 207a1 and the rotation axis of the pivot portion 191c1 is always greater than the distance between the contact position between the second arm 191c3 and the seventh protrusion 383 and the rotation axis of the pivot portion 191c1. As a result, the linear velocity of the seventh protrusion 383 is transmitted to the second arm 191c3, amplified by the first arm 191c2, and then transmitted to the first slider 207a, causing the first slider 207a to move forward at the second velocity and push the detection member within the image forming device.

[0428] During the swinging of the first arm 191c2, the locking protrusion 191c2a interferes with the second lever 207a1, causing them to elastically deform. This results in a compressive force perpendicular to the contact surface between the locking protrusion 191c2a and the second lever 207a1. As the first arm 191c2 swings until the locking surface is parallel to the lower surface of the second lever 207a1, the compressive forces exerted between the locking surface and the lower surface of the second lever 207a1 are opposite and equal in magnitude. This offsets the compressive forces, maintaining a stable relationship between the second lever 207a1 and the locking protrusion 191c2a, thereby securing the second lever 207a1 in place.

[0429] The eighth elastic member 188 applies a rearward force to the first slider 207a, and the reset arm 191h of the tenth elastic member 191 applies a clockwise rotational force to the first arm 191c2. However, when the contact surface between the lower surface of the second lever 207a1 and the locking surface is directly above the rotation axis of the pivot portion 191c1, the elastic deformation of the second lever 207a1 and the locking protrusion 191c2a is greatest. When the lower surface of the second lever 207a1 and the locking surface are parallel to each other, the contact surface between the lower surface of the second lever 207a1 and the locking surface is located forward of the rotation axis of the pivot portion 191c1 in the third direction. Therefore, the elastic deformation of the second lever 207a1 and the locking protrusion 191c2a is reduced. Therefore, the force applied by the eighth elastic member 188 on the first slider 207a and the force applied by the tenth elastic member 191 on the first arm 191c2 are insufficient to cause a greater deformation of the locking protrusion 191c2a and the second lever 207a1, and thus the first slider 207a and the rocker arm cannot be reset. As a result, the first slider 207a is stably locked by the locking protrusion 191c2a.

[0430] When the first slider 207a and the rocker arm need to be reset, the user only needs to manually pull the first slider 207a forward, and the second lever 207a1 will no longer apply pressure to the locking surface. The force balance is broken, and the rocker arm will automatically reset under the elastic force of the tenth elastic member 191. After the rocker arm is reset, the user lets go, and the eighth elastic member 188 will pull the first slider 207a to reset.

[0431] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
