Description

Technical Field

[0001] This invention relates to the field of electronic imaging technology, and particularly to a developing cartridge. Background Technology

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

[0003] The developing cartridge is usually installed in the image forming apparatus in a detachable manner. Currently, there are two installation methods: one is to install the developing cartridge directly into the main body of the image forming apparatus, and the other is to first install the developing cartridge into a drum unit, and then install it into the main body of the image forming apparatus together with the drum unit. Regardless of the installation method, in order for the developing cartridge to be accurately identified by the image forming apparatus, the existing developing cartridge is provided with a test piece for engaging with a preset test part in the image forming apparatus, and a power receiver for receiving driving force from a power output piece in the image forming apparatus.

[0004] The test piece drive head receives a driving force and is driven. When the test piece and the power receiver are on the same side, the driving force can be transmitted between them via gears. When the test piece and the power receiver are on different sides, in existing developing cartridges, the driving force is transmitted to the side where the test piece is installed via a stirring shaft installed in the developing cartridge, and then transmitted to the test piece via gears. Clearly, in order to drive the test piece, for structures where the test piece and the power receiver are on different sides of the developing cartridge, a set of gears needs to be installed on each side of the developing cartridge. The installation of these gears not only increases the material cost of the developing cartridge but also increases its assembly cost.

[0005] It is evident that the existing developing cartridges present operational difficulties and inconveniences when installed or removed from the image forming apparatus. Furthermore, the corresponding test components are not only complex in structure, but also prone to malfunction due to difficulty in identification. Summary of the Invention

[0006] According to one aspect of the present invention, a developing cartridge is provided, which is mounted on an image forming apparatus having a detection device, and comprises:

[0007] A housing for storing developer, having a first end and a second end disposed opposite to each other in a first direction;

[0008] A power receiving device, disposed in the housing, capable of receiving driving force from the image forming apparatus, is located at the first end;

[0009] The component to be detected, which is movably disposed in the housing and capable of triggering the detection device, is at least partially located at the second end;

[0010] A transmission component is movably disposed in the housing and is connected to the power receiving device via a transmission connection.

[0011] The first moving rod is connected to the transmission assembly and is driven by the transmission assembly to move in a first direction to push the detected component.

[0012] In some embodiments, the transmission assembly includes a fourth rotating member that is drively connected to the power receiving device, the fourth rotating member driving the first moving rod to move at a first speed and a second speed, the first speed being greater than the second speed.

[0013] In some embodiments, the transmission assembly includes a first inclined surface and a third inclined surface disposed on the fourth rotating member. The first inclined surface drives the first moving rod to move at a first speed, and the third inclined surface drives the first moving rod to move at a second speed.

[0014] In some embodiments, the angle between the first inclined surface and the end face of the fourth rotating component is greater than the angle between the third inclined surface and the end face of the fourth rotating component.

[0015] In some embodiments, the angle between the first inclined surface and the end face of the fourth rotating member is 50° to 70°.

[0016] In some embodiments, the angle between the third inclined surface and the end face of the fourth rotating member is 35° to 50°.

[0017] In some embodiments, the fourth rotating member is further provided with a fourth inclined surface, the angle between the fourth inclined surface and the end face of the fourth rotating member is the same as the angle between the third inclined surface and the end face of the fourth rotating member, and the fourth inclined surface drives the first moving rod to move at a second speed.

[0018] In some embodiments, the first, third, and fourth inclined surfaces are arranged sequentially along the circumferential direction and rotate with the fourth rotating component.

[0019] In some embodiments, a seventh elastic element is also included, which, together with the transmission assembly, causes the first moving rod to reciprocate in a first direction.

[0020] In some embodiments, the seventh elastic element is a spring, which is compressed when the first moving rod is driven by the transmission assembly to move in a first direction.

[0021] In some embodiments, a chip is also included, which is electrically connected to the image forming apparatus such that the image forming apparatus recognizes the developing cartridge.

[0022] The beneficial effects of the present invention are as follows: After the transmission component receives the driving motion of the power receiving device, it drives the first moving rod to move and push the component to be detected to contact and connect with the detection device. This can solve the problem that the developing cartridge is not easy to identify due to the complex connection relationship between the component to be detected and the detection device, so as to ensure the normal operation of the developing cartridge.

[0142] Example 1

[0143] like Figures 1 to 11 As shown, this embodiment discloses a developing apparatus that can be detachably mounted on a drum assembly in an image forming apparatus. The developing apparatus includes a housing 1, a developing assembly, a transmission assembly, a recognition assembly, a detection assembly, a power supply assembly, a first cover 111, and a second cover 121.

[0144] In the following descriptions of direction, perpendicular to Figure 1 When viewed from the direction of the middle paper, Figure 1 The left side of the middle page is left. Figure 1 The right side of the middle page is the right. Figure 1 The top of the middle paper is the upper part. Figure 1 The bottom of the middle paper is the lower side. Figure 1 The front side of the middle paper is the side closest to the front. Figure 1The far side of the middle paper is the back.

[0145] The cartridge body 1 has a cavity for containing developer. The cartridge body 1 has a first end 11 and a second end 12 oppositely arranged in a first direction; a third end 13 and a fourth end 14 oppositely arranged in a second direction; and a fifth end 15 and a sixth end 16 oppositely arranged in a third direction. A powder outlet is provided on the cartridge body 1, located at the third end 13. A handle 141 is provided on the cartridge body 1, located at the fourth end 14. A first cover 111 is detachably fixed to the first end 11 of the cartridge body 1 by screws or clips, and the first cover 111 protects the transmission assembly 2. A second cover 121 is detachably fixed to the second end 12 of the cartridge body 1 by screws or clips, and the second cover 121 protects the component being tested 3.

[0146] The developing assembly includes a developing roller 131, a powder feeding roller 440, and a stirring frame 240. The developing roller 131, powder feeding roller 440, and stirring frame 240 are all rotatably mounted within a receiving cavity between the first end 11 and the second end 12. The rotation axes of the developing roller 131, powder feeding roller 440, and stirring frame 240 all extend along a first direction. The developing roller 131 is located at the powder outlet. The powder feeding roller 440 is located adjacent to the developing roller 131. The powder feeding roller 440 is closer to the fourth end 14 of the cartridge 1 than the developing roller 131.

In the first direction, the large-diameter idler wheel is closer to the first end 11 of the cartridge body 1 than the small-diameter idler wheel.

[0149] The developing gear 43, the powder feeding gear 44, and the large-diameter first idler wheel 471 all mesh with the drive gear. The stirring gear assembly 24 meshes with the small-diameter idler wheel on the large-diameter first idler wheel 471. The meshing can be direct or indirect.

[0150] The rotation axis of the drive unit is closer to the fifth end 15 and the fourth end 14 of the cartridge 1 than the rotation axis of the developing roller 131, and the rotation axis of the drive unit is closer to the third end 13 of the cartridge 1 than the rotation axis of the stirring frame 240.

[0151] The stirring gear assembly 24 consists of a coaxially integrally formed first bushing 241, a second bushing 242, and a gear section. The diameter of the first bushing 241 is smaller than that of the second bushing 242, and the diameter of the second bushing 242 is smaller than that of the gear section. The first bushing 241 is fixedly mounted on the end of the stirring frame 240. The end of the first bushing 241 away from the box 1 in a first direction extends into the second bushing 242. A support wall is integrally formed between the end of the first bushing 241 away from the box 1 in the first direction and the inner wall of the second bushing 242. An annular groove is formed between the outer surface of the first bushing 241, the inner surface of the second bushing 242, and the support wall. A first elastic element 181 is installed in the annular groove and is sleeved on the first bushing 241. A first rotating element 21 is also installed on the first bushing 241. The first rotating element 21 has a coaxially formed shaft hole at its center and is coaxially and rotatably mounted on the first bushing 241 through the shaft hole. One end of the first elastic member 181 abuts against the side of the first rotating member 21 away from the housing 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 bushing 241, 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 bushing 241, extending along the first direction. The transmission key 21a6 is closer to the first end 11 of the housing 1 in the first direction than the end of the external thread. A keyway 21a5 matching the transmission key 21a6 is formed axially on the wall of the shaft hole. A stop block 33 is fixedly installed on the support column, and the stop block 33 is at the same position in the first direction as the end of the external thread near the housing 1 in the first direction. The stop block 33 is closer to the first end 11 of the housing 1 in the first direction than the first idler wheel 471. A first transmission protrusion 21a is integrally formed on the first rotating component 21. The first transmission protrusion 21a 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 circumferentially along the first rotating component 21. The surfaces of the first protrusion 21a1, the second protrusion 21a2, and the third protrusion 21a3 that are radially away from the rotation axis 296 of the first rotating component 21 are respectively the first contact surface, the second contact surface, and the third contact surface. 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 296 of the first rotating component 21. The central angle subtended by the first contact surface is larger than that of the second contact surface and the third contact surface. A fourth protrusion 21a4 extending radially is integrally formed on the first contact surface. The side of the fourth protrusion 21a4 that is radially away from the rotation axis 296 of the first rotating member 21 is the fourth contact surface. The fourth contact surface is an arc surface coaxial with the rotation axis 296 of the first rotating member 21, and the central angle subtended by the fourth contact surface is the same as the central angle subtended by the third contact surface. The radius of the fourth contact surface is larger than the radii of the first contact surface, the second contact surface, and the third contact surface.A positioning hole is formed on the third protrusion 21a3 along the first direction. A positioning post 21b is integrally formed on the first side wall of the box body 1 along the first direction, which mates with the positioning hole. 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 an integrally formed first positioning post 21b and a second positioning post 21b. The first positioning post 21b is located at the end of the second positioning post 21b away from the box body 1 in the first direction. The cross-sectional area of ​​the first positioning post 21b in the second direction is smaller than that of the second positioning post 21b.

The size of the first positioning hole 21a7 matches the size of the first positioning post 21b, and the size of the second positioning hole 21a8 matches the size of the second positioning post 21b. In the second direction, the positioning post 21b is located behind the rotation axis of the stirring rack 240, and the support post is located in front of the rotation axis of the stirring rack 240. The end of the stop block 33 that is 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.

[0152] The transmission assembly 2 also includes a first rocker arm 22, which extends through the receiving cavity and out of the housing 1 along a first direction. One end of the first rocker arm 22 is the receiving end, and the other end is the applying end. The receiving end of the first rocker arm 22 is located at the first end 11 of the housing 1, and the applying end of the first rocker arm 22 is located at the second end 12 of the housing 1. A first groove 112 and a second groove 123 are respectively formed on the first end 11 and the second end 12 of the housing 1. The first groove 112 and the second groove 123 extend along a second direction. The projections of the first groove 112 and the second groove 123 in the first direction coincide. An elastic film is formed between the first rocker arm 22 and the first groove 112 and the second groove 123 through secondary injection molding. The elastic film seals the first groove 112 and the second groove 123 to prevent developer leakage. A pivot extending along a third direction is integrally formed on the inner surface of the fifth end 15 of the housing 1, and the first rocker arm 22 is rotatably mounted on the pivot. The pivot is located at the center of the length of the first rocker arm 22. The force-receiving end of the first pendulum 22 is located above the first rotating member 21 in the vertical direction. A force-receiving protrusion 221 is integrally formed on the force-receiving end of the first pendulum 22, and the lower end of the force-receiving protrusion 221 is located within the movement trajectory of the first protrusion 21a1, the second protrusion 21a2, the third protrusion 21a3, and the fourth protrusion 21a4.

[0153] The component being tested 3 includes a third slider 31, and a slide rail with an open front end is integrally formed on the second cover 121. The third slider 31 is slidably mounted inside the slide rail. The front end of the third slider 31 is the end being tested 32. The end being tested 32 can extend from the front end of the slide rail. A first lever 31a is integrally formed on the right side wall of the third slider 31. The first lever 31a has a force-bearing surface, which is located in front of the force-applying end of the first lever 22. A mounting hole 321 is integrally formed on the third slider 31, and a mounting seat 1221 is integrally formed inside the slide rail. The mounting seat 1221 extends into the mounting hole 321, and a second elastic element 182 is installed between the rear side wall of the mounting hole 321 and the mounting seat 1221.

[0154] The component being tested 3 has a first state and a second state. In the first state, in the second direction, the force-receiving end of the first lever 22 is closer to the fourth end 14 of the housing 1 than the force-applying end. The force-receiving surface on the first lever 31a is supported by the force-applying end, so that the tested end 32 is in the state of extending out of the slide rail, and the second elastic member 182 is in the stretched state.

[0155] In the second state, the force-receiving end of the first lever 22 in the second direction is further away from the fourth end 14 of the housing 1 than the force-applying end. The detection end 32 of the first lever 31a is located inside the slide rail, and the second elastic element 182 does not undergo elastic deformation.

[0156] The power supply assembly includes a conductive element located at the second end 12 of the housing 1. The conductive element has an electrical receiving surface 51 and also includes 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 feeding roller 440 near the second end 12 of the housing 1. The electrical receiving surface 51 is used to contact the power supply unit on the image forming apparatus to receive electrical energy output from the image forming apparatus and to transmit the electrical energy to the developing roller 131 and the powder feeding roller 440 to form a bias voltage between them. The electrical receiving surface 51 is located in the second direction between the rotation axis of the stirring frame 240 and the developing roller 131.

[0157] The identification component includes a storage medium and an electrical contact surface 5. The storage medium stores data, and the electrical contact surface 5 contacts and is electrically connected to the identification contacts within the image forming apparatus. The storage medium is fixedly mounted on the first cover 111, and the electrical contact surface 5 is fixedly mounted on and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end face of the storage medium. A third direction intersects with the electrical contact surface 5. In a second direction, 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, the distance between the electrical contact surface 5 and the rotation axis of the drive unit is less than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame 240.

[0158] By adopting the design disclosed in this embodiment, the second end 12 of the cartridge 1 does not need to be designed with a large number of transmission mechanisms for transmission, which reduces the volume of the second end 12 of the cartridge 1, which is conducive to the miniaturization of the developing device. Furthermore, after reducing the transmission mechanism, the second cover 121 can also be made smaller, saving materials and space.

[0159] The following describes the operation of the developing apparatus disclosed in this embodiment. The developing apparatus is installed onto the drum assembly within the image forming apparatus. The power output shaft of the image forming apparatus is connected to the power receiving device 4. The identification contact within the image forming apparatus contacts the electrical contact surface 5 and reads the information stored in the storage medium to identify information such as the model, capacity, and lifespan of the developing apparatus.

[0160] The developing apparatus disclosed in this embodiment has a factory-preset state. In this factory-preset state, the side of the first rotating member 21 away from the first end 11 of the housing 1 in the first direction abuts against the side of the stirring gear assembly 24 close to the first end 11 of the housing 1 in the first direction. The first elastic member 181 is in a compressed state. The force-receiving protrusion 221 of the first swing rod 22 contacts and is limited by the first protrusion 21a1. In this factory-preset state, the detected component 3 is in a first state. In the first state, the first swing rod 22 is not parallel to the first direction. In the second direction, the force-receiving end of the first swing rod 22 is closer to the fourth end 14 of the housing 1 than the force-applying end. The force-receiving surface on the first lever 31a is supported by the force-applying end, causing the detected end 32 to be in a state of extending out of the slide rail. The second elastic member 182 is in a stretched state.

[0161] When the developing device is installed onto the drum assembly in the image forming apparatus, the detected end 32 of the developing device in its initial state is extended from the slide rail. Therefore, the detected end 32 will contact the detector in the image forming apparatus and apply a pushing force to the detector, causing the detector to generate an electrical signal, thereby enabling the image forming apparatus to detect that the developing device has been installed.

[0162] When the image forming apparatus receives a print command, it begins to output power to the power receiving device 4, causing the power receiving device 4 to rotate around... Figure 4 The clockwise rotation of the roller 131 causes the drive gear to rotate along with the power receiving device 4, which in turn drives the developing gear 43, the powder feeding gear 44, and the large-diameter first idler wheel 471 to rotate counterclockwise. The small-diameter idler wheel rotates counterclockwise along with the large-diameter first idler wheel 471. The small-diameter idler wheel drives the stirring gear assembly 24 to rotate clockwise. This causes the developing roller 131, the powder feeding roller 440, and the stirring frame 240 to all begin operating.

[0163] Simultaneously, the stirring gear assembly 24 drives the first bushing 241 and the second bushing 242 to rotate. Due to the friction between the external thread on the first bushing 241 and the internal thread on the first rotating member 21, the first rotating member 21 rotates together with the first bushing 241. The first protrusion 21a1, the second protrusion 21a2, the third protrusion 21a3, and the fourth protrusion 21a4 also rotate together with the first rotating member 21. Then, the side wall of the first protrusion 21a1 abuts against the stop block 33, preventing the first rotating member 21 from continuing to rotate with the first bushing 241. At this time, under the action of the threads, the first rotating member 21 is displaced relative to the first bushing 241 in the first direction, and the first rotating member 21 moves towards the box body 1. At this time, the force-bearing protrusion 221 still maintains contact with the first contact surface on the first protrusion 21a1, keeping the first rocker arm 22 in the first state.

[0164] Then, as the first bushing 241 rotates, the first rotating member 21 continues to move towards the housing 1 along the first direction, blocked by the stop block 33. Until the first rotating member 21 disengages from the external thread on the first bushing 241, the keyway 21a5 on the first rotating member 21 aligns with the transmission key 21a6 on the first bushing 241 and enters a mating state. Simultaneously, the side of the first rotating member 21 closest to the housing 1 abuts against the positioning post 21b, preventing the first rotating member 21 from continuing to move in the first direction. Under the action of the transmission key 21a6, the first rotating member 21 begins to rotate together with the first bushing 241.

[0165] As the first bushing 241 rotates, the first protrusion 21a1 disengages from the force-bearing protrusion 221 of the first rocker arm 22. At this time, under the elastic force of the second elastic element 182, the object being tested moves to the second state, so that the end being tested 32 no longer pushes the object being tested. This ends the first push on the object being tested.

[0166] Then, as the first rotating member 21 rotates, the second protrusion 21a2 contacts the force-receiving protrusion 221 of the first swing rod 22 and pushes the force-receiving protrusion 221, causing the detected component to move to the first state. The detected end 32 of the third slider 31 then pushes the detected component again. Afterward, the second protrusion 21a2 disengages from the force-receiving protrusion 221, and 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 detected component, thus ending the second push on the detected component.

[0167] Then, as the first rotating member 21 rotates, the third protrusion 21a3 contacts the force-receiving protrusion 221 of the first swing rod 22 and pushes the force-receiving protrusion 221, causing the tested component to move to the first state. The tested end 32 of the third slider 31 then pushes the tested component again. Afterward, the third protrusion 21a3 disengages from the force-receiving protrusion 221, and under the elastic force of the second elastic member 182, the tested component 3 moves to the second state. The tested end 32 no longer pushes the tested component, thus ending the third push on the tested component.

[0168] Then, as the first rotating member 21 rotates, the first positioning hole 21a7 rotates to align 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. Simultaneously, the first positioning post 21b inserts into the first positioning hole 21a7. Both the first positioning hole 21a7 and the second positioning hole 21a8 are arc-shaped, allowing the first positioning post 21b to slide relative to the first positioning hole 21a7 within the first positioning hole 21a7. Since the cross-sectional area of ​​the first positioning post 21b is smaller than that of the second positioning post 21b, the second positioning post 21b cannot enter the first positioning hole 21a7, causing the second positioning post 21b to abut against the end face 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 arm 22, causing the detected component 3 to move to the first state. Since the radius of the fourth protrusion 21a4 is larger than that of 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 arm 22, the third slider 31 moves to the first state at the first speed. However, the fourth protrusion 21a4 has a faster linear velocity, causing the detected component 3 to enter the first state at a second speed that is faster than the first speed. This causes the detected end 32 to push the detected component for the fourth time. Then, as the first rotating member 21 rotates... When the first rotating member 21 rotates, the second positioning post 21b aligns 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 closer to the box 1, causing the second positioning post 21b to enter the second positioning hole 21a8. At the same time, the transmission key 21a6 disengages from the keyway 21a5, so that the first rotating member 21 can only move under the action of friction between itself and the first bushing 241. The side wall of the second positioning hole 21a8 abuts against the second positioning post 21b, thereby offsetting the friction between the first bushing 241 and the first rotating member 21, thus preventing the first rotating member 21 from continuing to rotate and achieving the positioning of the first rotating member 21.

[0169] Example 2

[0170] This embodiment discloses a processing box, which includes a developing box and a photosensitive element box. The developing box is provided with a component to be tested 3. The photosensitive element box is provided with at least one power receiving device 4, which can provide power to the photosensitive drum 81 on the photosensitive element box. At the same time, the power receiving device 4 on the photosensitive element box can also provide external driving force to the developing box, thereby causing the developing roller 131 on the developing box to rotate.

[0171] Figures 12 to 13 According to this embodiment, a photosensitive element box includes a photosensitive frame 801 arranged along a first length direction and a power receiving device 4 arranged on one side of the first direction. The power receiving device 4 includes a first power receiving block 811 for receiving external power and a photosensitive transmission part 811a connected to the first power receiving block 811. A second power receiving block 812 is arranged near 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 box.

[0172] Figure 14 A schematic diagram of the developing cartridge and photosensitive element cartridge in the processing cartridge is shown. The developing cartridge stores developer and has a developing roller 131 that supplies developer to the photosensitive drum 81 on the photosensitive element cartridge. A chip is disposed on the developing cartridge body 1 at the other end in a first direction relative to the component being detected 3. The chip has an electrical contact surface 5, which can be electrically connected to the image forming apparatus, enabling the image forming apparatus to identify or detect a new developing cartridge.

[0173] The developing cartridge has a first end 11 and a second end 12 in a first direction. Specifically, the developing cartridge includes a cartridge body 1, a developing roller 131, and a component to be tested 3. The component to be tested 3 is located on the cartridge body 1 near the second end 12. The component to be tested 3 protrudes from the cartridge body 1 and is used to contact or separate from a detection lever of an image forming apparatus (not shown). Detection is triggered by a change in the state between the component to be tested 3 and the detection lever, for example, the two can be connected / disconnected. When the component to be tested 3 is disconnected from the detection lever, i.e., the electrical connection is broken, the image forming apparatus can perform detection of the developing cartridge by this change in state.

[0174] According to this embodiment, the developing cartridge receives the driving force of the image forming apparatus via a power receiving device 4 on the photosensitive element cartridge. This, in turn, drives the developing roller 131 on the developing cartridge and the component being tested 3. Figure 14 As shown, in the initial state of the developing cartridge before it is engaged with the photosensitive element cartridge according to this embodiment, when the developing cartridge is installed inside the photosensitive element cartridge, the photosensitive transmission part 811a of the power receiving device 4 on the photosensitive element cartridge engages with the transmission gear set 45 of the developing roller 131 on the developing cartridge, the powder feeding gear 44 of the powder feeding roller 440 (not shown), and the stirring gear set 24 of the stirring frame 240 (not shown).

[0175] Example 3

[0176] Figure 15 This diagram illustrates another overall structure of the developing cartridge and the photosensitive element cartridge within the processing cartridge;

[0177] like Figure 15 As shown, a processing cartridge includes a developing cartridge and a photosensitive element cartridge.

[0178] The photosensitive element box includes a photosensitive frame 801 arranged along a first length direction and a power receiving device 4 arranged on one side of the first direction. The power receiving device 4 includes a power receiving section 41 for receiving external power and a photosensitive transmission section 811a connected to the power receiving section 41. The photosensitive transmission section 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 4 in the first direction on the photosensitive element box. The chip and the core frame are located at the end of the photosensitive drum 81 (not shown) on the photosensitive element box in a second direction away from the second end. The chip has an electrical contact surface 5.

[0179] The developing cartridge stores developer and has a developing roller 131 that supplies developer to the photosensitive drum 81 (not shown) on the photosensitive element cartridge. It has a first end 11 and a second end 12 in a first direction. The developing cartridge also includes a cartridge body 1 and a detection component 3. The detection component 3 is located at the second end 12 in the first direction on the developing cartridge body 1, and a transmission component is located relative to the first end 11 of the detection component 3. The transmission component includes a developing gear 43 that provides power to the developing roller 131, and a powder feeding roller 440 that applies powder to the developing roller 131. It also includes a stirring frame 240 (not shown) for stirring the developer within the cartridge body 1, and a stirring gear set 24 that provides power to the stirring frame 240 to agitate the developer within the cartridge body 1. Simultaneously, the transmission component provides power to the component being tested 3, which protrudes from the housing 1 and is used to contact or separate from the detection lever of the image forming apparatus (not shown). Detection is triggered by the state change between the component being tested 3 and the detection lever, for example, the two can be connected / disconnected. When the component being tested 3 is disconnected from the detection lever, the image forming apparatus can perform detection on the developing cartridge by this state change.

[0180] When the developing cartridge is installed inside the photosensitive element cartridge, the photosensitive drive unit 811a on the photosensitive element cartridge engages with the drive gear set 45 of the developing roller 131 on the developing cartridge, the powder feeding gear 44 of the powder feeding roller 440 (not shown), and the stirring gear set 24 of the stirring frame 240 (not shown). This causes the developing roller 131 on the developing cartridge to rotate. When the developing cartridge and the photosensitive element cartridge are placed into the image forming apparatus, the drive head of the image forming apparatus engages with the power receiving unit 41 on the photosensitive element cartridge, thereby driving the photosensitive drum 81 on the photosensitive element cartridge to rotate. Simultaneously, since the developing cartridge is installed inside the photosensitive element cartridge, its photosensitive drive unit 811a engages with the drive gear set 45 of the developing roller 131 on the developing cartridge, the powder feeding gear 44 of the powder feeding roller 440 (not shown), and the stirring gear set 24 of the stirring frame 240 (not shown). Power is simultaneously transmitted to the inspected component 3, thereby causing the inspected component 3 to detach from or contact the image forming apparatus, thus enabling the inspected component 3 to operate or cease operation. Furthermore, since the chip is located on the photosensitive element box, when the developing box and the photosensitive element box are placed into the image forming apparatus as a whole, an electrical connection between the chip and the image forming apparatus can be achieved.

[0181] Example 4

[0182] Figure 16 This diagram illustrates another structural design of the developing cartridge and photosensitive element cartridge within the processing cartridge; a key difference from the embodiment is the inclusion of a chip holder on the photosensitive element cartridge. The power receiving unit 41 and the photosensitive transmission unit 811a of the power receiving device 4 are mounted on the developing cartridge.

[0183] like Figure 16 As shown, a processing cartridge includes a developing cartridge and a photosensitive element cartridge.

[0184] The photosensitive element box includes a photosensitive frame 801 disposed along a first length direction and a photosensitive drum 81, which can provide a rotational drive head (not shown) to the photosensitive drum 81. A chip and a core frame supporting the chip are disposed on one side of the photosensitive element box in the first direction. The chip and the core frame are located at the end of the photosensitive element box away from the photosensitive drum 81 in a second direction.

[0185] The developing cartridge stores developer and has a developing roller 131 that supplies developer to the photosensitive drum 81 on the photosensitive element cartridge. It has a first end 11 and a second end 12 in a first direction. The developing cartridge also includes a cartridge body 1 and a test component 3. The test component 3 is located at the second end 12 in the first direction on the developing cartridge body 1, and a power receiving device 4 is located relative to the first end 11 of the test component 3. The power receiving device 4 includes a power receiving section 41 that provides transmission force to the image forming apparatus, and a photosensitive transmission section 811a that connects to the power receiving section 41 and transmits power. It also includes a stirring rack 240 (not shown) for stirring the developer inside the cartridge body 1, and a stirring gear set 24 that provides power to the stirring rack 240 to agitate the developer inside the cartridge body 1. At the same time, the photosensitive transmission unit 811a provides power to the component under test 3, which protrudes from the housing 1 and is used to contact or separate from the detection lever of the image forming apparatus (not shown). Detection is triggered by the state change between the component under test 3 and the detection lever, for example, the two can be connected / disconnected. When the component under test 3 is disconnected from the detection lever, the image forming apparatus can perform detection of the developing cartridge by this state change.

[0186] Example 5

[0187] Figures 17 to 19 The diagram shows a schematic of a novel test component 3 for a developing cartridge. As shown in the figure, the developing cartridge is detachably mounted in an image imaging device equipped with a detection device 7. The developing cartridge has a developing roller 131 that provides developer to the photosensitive drum 81 on the photosensitive element cassette, and 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 test component 3 is disposed at the second end 12 in the first direction on the developing cartridge body 1, and a power receiving device 4 is disposed relative to the first end 11 of the test component 3.

[0188] The power receiving device 4 and the component being tested 3 are located at the longitudinal ends of the housing 1, respectively. The power receiving device 4 is used to receive driving force from the outside, and the component being tested 3 is used to combine with the external detection device 7 so that the developing housing can be detected by the image imaging device. The developing housing also includes a first transmission rod 25 rotatably installed in the housing 1. The first transmission rod 25 is driven by the driving force received by the power receiving device 4. The component being tested 3 is coaxially arranged with the first transmission rod 25.

[0189] More details such as Figure 18 As shown, Figure 18 The diagram shows the connection between the power receiving device 4 and the tested component 3 after the end cap 6 of the developing cartridge and the cap on the cartridge body 1 have been removed. Figure 18As shown, the power receiving device 4 includes a power receiving unit 41 that receives external transmission force and a power transmission photosensitive transmission unit 811a. It also includes a developing gear 43 meshing with the photosensitive transmission unit 811a, a powder feeding gear 44, a transfer gear, a secondary stirring gear set 24, and a transmission gear set 45 consisting of a first stirring tooth, a second stirring tooth, and a detection gear 46 of the second stirring tooth in the stirring gear set 24.

[0190] When the power receiving device 4 receives external driving force from the image forming device, the detected component 3 can be driven by the transmission gear set 45 of the transmission system and driven by the first transmission rod 25.

[0191] After the developing cartridge is installed into the imaging device, the detected component 3 is driven to rotate, thereby enabling the developing cartridge to be detected by the imaging device. After the imaging device has completed the detection, the detected component 3 no longer needs to rotate. For this reason, the detection gear 46 installed at the other end of the first transmission rod 25 is set as a toothed gear, such as... Figure 18 As shown, a portion of the circumferential surface of the detection gear 46 (the toothless portion 461) is a smooth surface, meaning that no teeth are provided in this portion. When the toothless portion 461 of the detection gear 46 is opposite to the second gear, the detection gear 46 will no longer be driven by the second gear and will stop rotating. Consequently, the first transmission rod 25 and the detected component 3 will also stop rotating. In fact, when the developing cartridge is working, it needs to receive not only driving force from the image imaging device but also electricity from the image imaging device. In the developing cartridge of the present invention, the electrical receiving surface 51 for receiving electricity is provided with a detection end in the first direction, and the electrical receiving surface 51 supplies the electricity received from the image imaging device to the developing element and the powder feeding roller 440 simultaneously. This design also helps to simplify the structure of the developing cartridge. That is, it is not necessary to provide electrical receiving surfaces 51 separately for the developing roller 131 and the powder feeding roller 440 (not shown); only one electrical receiving surface 51 is needed. Figure 20 The diagram also shows a first transmission rod 25, a stirring rack 240 disposed inside the developing cartridge 1, and stirring blades disposed on the stirring element. The tested assembly 3 is also provided with a plurality of first detection protrusions 34, which protrude in a first direction away from the cartridge 1. In this embodiment, the electrical receiving surface 51 is configured as an electrical receiving element.

[0192] Preferably, the first transmission rod 25 and the stirring rack 240 are integrated, meaning they can be coaxially arranged. This means that the developing cartridge can transmit power from the power receiving end to the detection end in the first direction solely through the stirring rack 240.

[0193] Example 6

[0194] This embodiment is an improvement and modification of the scheme in Embodiment 5, based on problems encountered in actual production. In Embodiment 5, the detection is triggered by the rotation of the component under test 3 around the first axis. In this embodiment, the detection is triggered by the extension or retraction of the component under test 3 along the second direction.

[0195] Figure 20 This is a perspective view of the developing cartridge in this embodiment. Figure 20 As shown, the power receiving device 4 is disposed at the first end 11 at both ends of the processing cartridge along its length (first direction), and the component being detected 3 is disposed at the second end 12 at both ends of the processing cartridge along its length. The transmission relationship between the power receiving device 4 and the component being detected 3 is different from that in the aforementioned embodiments. It is transmitted to the second rotating member 26 via the stirring frame 240 or the transmission shaft and gear set. The rotating member at the detection end triggers the component being detected 3, causing the component being detected 3 to move telescopically within the third slide groove 260 under the action of the third elastic member 183. The developing cartridge also includes a cartridge body 1 containing developer and an electrical receiving surface disposed on the same side as the component being detected 3 in the first direction. The electrical receiving surface provides an electrical connection to the developing cartridge through the image forming apparatus. The component being detected 3 is disposed on the end cover 6 of the developing cartridge. The end cover 6 is disposed on the side away from the cartridge body 1 in the first direction by the third slide groove 260.

[0196] Figure 21 A magnified perspective view of a portion of the counting gear section after removing end cap 6. (See attached image.) Figure 21 As shown, the developing cartridge receives external power through the first end 11 of the power receiving unit 41, and transmits the power to the second rotating member 26 at the detection end in the first direction of the developing cartridge through the internal drive shaft / rod, the stirring frame 240, the developing roller 131, or the powder feeding roller 440. The second rotating member 26 is rotatably mounted on the cartridge body 1 in the first direction. The second rotating member 26 is provided with a plurality of second drive protrusions 261, located at the end of the second rotating member 26 away from the cartridge body 1. It drives and has the tendency to push or maintain the protrusion 35 of the detected component 3 away from or near the detection position of the image forming apparatus. The detected component 3 also includes a fixing part, one end of the third elastic member 183 is sleeved on the fixing part, and the other end of the third elastic member 183 abuts against the third sliding groove 260. It also includes a mating part that cooperates with the third slide groove 260, and the component being tested 3 can slide freely in the third slide groove 260. The third slide groove 260 is provided with limiting parts on both sides in the second direction, which can protect the component being tested 3 from excessive ejection under the action of the third elastic member 183.

[0197] like Figure 22 As shown, the movement direction of the detected component 3 is preferably a telescopic movement along the second direction. Under normal conditions, the detected component 3 is in the free state of the third elastic member 183, and the detected part 30 extends in the second direction to trigger the detection device 7 of the image forming apparatus.

[0198] When the second transmission protrusion 261 of the second rotating member 26 abuts against the protrusion 35 of the detected component 3, the detected component 3 is pressed, and the detected component 3 moves away from the detection device 7 of the image forming apparatus in the second direction, that is, the third elastic member 183 is pressed. At this time, the detected part 30 does not contact the detection device 7 of the image forming apparatus in the second direction, that is, it is in a non-triggered state. When the second transmission protrusion 261 of the second rotating member 26 is not in contact with the protrusion 35, the detected part 30 extends in the second direction under the action of the third elastic member 183. Thus, it continues to trigger the detection device 7 of the image forming apparatus, thereby realizing the detection counting or identification of the developing cartridge by the image forming apparatus.

[0199] It is conceivable that the third elastic element 183 could also be a tension spring, a torsion spring 190, an elastic sheet, or other components that can deform and recover from deformation.

[0200] A more preferred approach is for the detected component 3 to directly extend and retract along the first direction. Specifically, a transmission rod can extend directly from the power receiving end. This transmission rod can extend and retract along the first direction, without the third elastic element 183. Using a cam or lever, the transmission rod can have a first position and a second position in the first direction, with the second position extending out of the developing cartridge 1 in the first direction and triggering the detection device 7 of the image imaging apparatus. Furthermore, the extension and retraction of the detected component 3 along the first or second direction, thereby triggering the detection device 7 of the image imaging apparatus and enabling the image imaging apparatus to detect and identify the developing cartridge, should all be included within the protection scope of this embodiment.

[0201] Example 7

[0202] This embodiment provides another processing box, and the parts not shown are the same as the processing box structures in Embodiments 5 and 6.

[0203] The difference between this embodiment and embodiments five or six is ​​that the component 3 to be detected in the processing box of this embodiment swings relative to the processing box body.

[0204] Specifically, such as Figures 23 to 25As shown, similar to the previous embodiment, the component being tested 3 is located at one end of the developing cartridge in a first direction. It 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 swing member 27 for triggering the component being tested 3. The swing member 27 includes a first swing end 272, a second swing end 273, and a swing ring 271. The swing member 27 is disposed on the end cover 6 of the developing cartridge. The end cover 6 includes a movement space 62 for accommodating the swing member 27, and a rotating protrusion 61 that cooperates with the swing ring 271 of the swing member 27. Its purpose is to allow the swing member 27 to swing around the rotating protrusion 61 within the movement space 62.

[0205] The specific working principle is that one end of the swing member 27 extends along the first direction of the developing cartridge and is far away from the developing cartridge body 1, while the other end is closer to the cartridge body 1 relative to the first swing end 272, and the second swing end 273 can abut or disengage from the second transmission protrusion 261.

[0206] When the second swing end 273 comes into contact with the second transmission protrusion 261, the swing member 27 swings around the rotating protrusion 61, and the first swing end 272 tilts up to make contact with the detection device 7 of the image forming apparatus, thereby triggering the image forming apparatus to recognize or detect the developing cartridge.

[0207] When the second swing end 273 disengages from the second transmission protrusion 261, the swing member 27 swings around the rotating protrusion 61, and the first swing end 272 disengages from the detection device 7 of the image forming apparatus, thereby not touching the detection device 7 of the image forming apparatus.

[0208] Example 8

[0209] Another structural feature, different from embodiments two, three, and four, is that a chip holder and / or the component to be detected 3 are provided on the photosensitive element cartridge. The power receiving unit 41 and the photosensitive transmission unit of the power receiving device 4 are provided on the developing cartridge. The power receiving device 4 receives the driving force of the image forming apparatus. The component to be detected 3, located on the photosensitive element cartridge, is activated via the transmission rod of the toner cartridge, thereby interacting with the detector on the image forming apparatus, thus enabling the image forming apparatus to detect and identify the toner cartridge. Other features are the same as in embodiments two, three, and four, and will not be elaborated here.

[0210] Example 9

[0211] This embodiment provides another processing box, which differs from embodiments three and four in that it provides rotational power to the photosensitive drum 81 through only one power receiving device 4 on the photosensitive element box, and simultaneously drives the developing box through the cooperation of the developing box series gear set.

[0212] Please refer to the details. Figures 26 to 29 .like Figure 26 As shown, a processing cartridge structure is illustrated, including a developing cartridge and a photosensitive element cartridge. The developing cartridge includes a cartridge body 1, a first end 11 disposed along a first direction, and a second end 12 disposed in the first direction relative to the first end 11. A power receiving device 4 is disposed on the side of the photosensitive element cartridge closer to the first end 11 in the first direction and farther away from the developing cartridge in the second direction. The power receiving device 4 includes a power receiving section 41, which may be equipped with a gear structure.

[0213] like Figure 27 This diagram shows the position of the developing cartridge before it is installed into the image sensor cartridge. Details are as follows... Figure 27 As shown, the developing cartridge also includes a tested component 3, a developing roller 131 for supplying developer to the photosensitive element cartridge, and a developing gear 43 disposed on one side of the cartridge body 1 along a first direction. The developing gear 43 is located at the end of the developing cartridge in a second direction closer to the mounting direction. More detailed information is as follows... Figure 27 As shown, the photosensitive element box also includes a receiving section, which mainly accommodates the developing cartridge when it is fitted with the photosensitive element box along the mounting direction. The photosensitive element box also includes a frame and a power receiving section 41 disposed on one end of the frame along a first direction. When the developing cartridge is fully installed inside the photosensitive element box, the power receiving section 41 engages with the developing gear 43, thereby enabling the power receiving device 4 on the photosensitive element box to provide power input to the developing roller 131 on the developing cartridge.

[0214] Figure 28 This diagram shows a structural view of the developing cartridge and the photosensitive element cartridge at another angle. The component to be tested, 3, is positioned on the side of the developing cartridge opposite the developing gear 43 along the first direction. Figure 29 This diagram shows a partial structural fit after removing the photosensitive element cartridge frame and the upper casing 1 of the developing cartridge. The photosensitive drum 81 receives external power through a power receiving device 4. The developing gear 43 receives power by meshing with the gear of the power receiving device 4, thereby driving the developing roller 131 to rotate. The developing roller 131 transfers toner from the developing cartridge casing 1 to the photosensitive drum 81 via a toner feeding roller 440. Simultaneously, a first gear is located on the side of the toner feeding roller 440 near the developing gear 43. This first gear, through its engagement with the developing gear 43, provides rotational power to the toner feeding roller 440. A second gear is located on the other side of the toner feeding roller 440, positioned away from the developing gear 43 along a first direction. This second gear engages with the gear of the stirring rack 240 via a first idler gear 471. The gear of the stirring rack 240 is located at the end away from the developing gear 43 in the first direction. It can provide power to the component being tested 3. Furthermore, when the entire processing cartridge begins to operate within the image forming apparatus, the detected component 3 on the developing cartridge achieves detection and recognition with the image forming apparatus.

[0215] Figure 30 Another power transmission mechanism between the developing cartridge and the photosensitive element cartridge is shown. The developing cartridge is equipped with a developing gear 43, which cooperates with the power receiving device 4 of the photosensitive drum 81 to receive external driving force. It can also cooperate with a powder feeding gear 44 located on the same side of the developing cartridge to realize power transmission to the powder feeding roller 440. The powder feeding gear 44 transmits power to the stirring gear set 24 through a first idler gear 471. The stirring gear set 24 is located on the same side of the developing cartridge and the developing gear 43. Through the power input, the stirring frame 240 is driven to rotate, and the power is transmitted to the tested component 3 through the other side of the developing cartridge relative to the developing cartridge gear.

[0216] Example 10

[0217] This embodiment provides another processing box, which differs from embodiment nine in that it provides rotational power to the photosensitive drum 81 through only one power receiving device 4 on the photosensitive element box. At the same time, through the cooperation of the transmission gear at the other end of the photosensitive drum 81 and the series gear set at the other end of the developing box, the developing roller 131, the powder feeding roller 440, the stirring frame 240, and the detected component 3 of the developing box are driven simultaneously. Details are as follows.

[0218] Figure 31 This diagram illustrates the structural arrangement of the developing cartridge and the photosensitive drum 81 within the photosensitive element cartridge of Embodiment 10. More detailed details are shown below. Figure 32 The diagram shows the processing cartridge of Embodiment 10, and the third-view structural diagram of the position where the developing cartridge mates with the photosensitive drum 81 of the photosensitive element cartridge.

[0219] As shown in the diagram, the photosensitive drum 81 has a first photosensitive gear along a first direction to receive external power, and a second photosensitive gear at the other end opposite the first photosensitive gear. A developing gear 43 cooperates with the second photosensitive gear. A powder feeding gear 44 cooperates with the developing gear 43, and its rotation drives the powder feeding roller 440 to rotate. There are also a first idler wheel 471, a second idler wheel 471, and a stirring gear assembly 24 cooperating with the second idler wheel 471. The stirring gear assembly 24 drives the stirring frame 240 to rotate, and the stirring frame 240 has blades for stirring the developer, ensuring uniform stirring of the developer inside the developing cartridge. A detection component 3 is located on the same side as the developing gear 43, and its movement is achieved by cooperating with the stirring gear assembly 24. Therefore, when the entire processing cartridge begins operation within the image forming apparatus, the detection component 3 on the developing cartridge is detected and identified by the image forming apparatus.

[0220] Example 11

[0221] This embodiment provides another processing box, which differs from embodiment five in that the drive end of the component being tested 3 is located at one end of the developing cartridge, while the tested part 30 of the component being tested 3 is located at the other end of the developing cartridge. Power can be transmitted from the drive end of the developing cartridge to the tested part 30 by means of telescopic movement, etc. Furthermore, the drive end has multiple protrusions, while the tested part 30 of the component being tested 3 has only one protrusion. A drive head on the developing cartridge provides rotational power to the developing roller 131, and simultaneously, a series of transmission gear sets 45 drives the powder feeding roller 440, the stirring frame 240, and the component being tested 3.

[0222] Figure 33 The diagram shows a novel test component 3 of a developing cartridge. Details are as follows... Figure 33 As shown, the developing cartridge is detachably mounted in an image imaging apparatus equipped with a detection device 7. The developing cartridge has a developing roller 131 that provides developer to the photosensitive drum 81 (same as in Embodiment 5) on the photosensitive element cartridge, and 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 detection component 3 is disposed on the second end 12 in the first direction on the developing cartridge body 1, and a power receiving device 4 is disposed opposite to the first end 11 of the detection component 3. It also includes a chip (not shown) electrically connected to the image forming apparatus. The developing cartridge body 1 further includes a developing gear 43 that provides power to the developing roller 131, and electrodes disposed on the opposite side of the developing gear 43 along the first direction. It also includes a cover for the driving end of the cartridge body 1 and an end cap 6 for the detection end.

[0223] The power receiving device 4 and the detected component 3 are located at the two longitudinal ends (first direction) of the cartridge 1, respectively. 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 7 so that the developing cartridge can be detected and identified or counted by the image imaging device. The developing cartridge also includes a second transmission rod 28 (not shown) rotatably installed in the cartridge 1. The second transmission rod 28 is driven by the driving force received by the power receiving device 4.

[0224] More details such as Figure 34 As shown, Figures 34 to 35This is a schematic diagram showing the position of the tested component 3 and the overall cavity structure of the developing cartridge after the cover of cartridge body 1 has been removed. As shown in the diagram, the tested component 3 is located on one side of the developing cartridge body 1 along the first direction, and has a second detection protrusion 36. A second transmission rod 28 passes through both ends of the cartridge body 1. The second detection protrusion 36 is located at one end of the second transmission rod 28. A driving part is provided at the other end of the second transmission rod 28 relative to the second detection protrusion 36. The driving part includes a connecting protrusion 281. The transmission component 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 one of the gears in the developing cartridge transmission gear set 45, or it can be non-coaxial with any one of the gears in the developing cartridge transmission gear set 45.

[0225] Figures 35 to 36 As can be seen, when the third rotating part 29 comes into contact with the connecting protrusion 281, the fourth elastic part 184 is under pressure, and the second transmission rod 28 moves towards the end of the component being tested 3 along the first direction, thereby driving the second detection protrusion 36 to move away from the box 1, thus achieving trigger contact with the detection device 7. Figure 36 In the middle, a chip is also provided on one side of the third rotating part 29. The chip can realize electrical connection with the electronic image imaging device and is mainly used for the electronic image imaging device to electrically identify or count the developing cartridge.

[0226] More details such as Figure 37 The specific structure of the third rotating member 29 of the developing cartridge is shown, which includes multiple 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 abuts against the connecting protrusion 281, the second transmission rod 28 can cause the second detection protrusion 36 to move away from the cartridge 1 along the first direction for a duration as long as the other rotating protrusions 290. In other words, when at least one rotating protrusion 290 interacts with the connecting protrusion 281, the second detection protrusion 36 has a longer detection time with the image forming apparatus. Furthermore, through the action of the fourth elastic member 184, the second detection protrusion 36 can achieve axial extension and retraction along the first direction.

[0227] A more accurate understanding could be that the timing of the second detection protrusion 36 being triggered by the image forming apparatus is determined by the time it interacts with the connecting protrusion 281 through the different shapes of the rotating protrusion 290 and the interaction time through the fourth elastic element 184.

[0228] Figure 38A more detailed structure of the third rotating member 29 is shown, which includes rotating protrusions 290, at least one rotating tooth 294, at least one rotating toothed portion 295, and a rotating shaft 296. When the drive gear set 45 of the developing cartridge drives the rotating tooth 294 of the third rotating member 29 to rotate, the plurality of rotating protrusions 290 can rotate along the rotating shaft 296, thereby achieving abutment against the connecting protrusion 281, which in turn drives the second transmission rod 28 and the second detection protrusion 36 to move. This enables the second detection protrusion 36 to trigger the detection of the image forming apparatus.

[0229] Example 12

[0230] This embodiment provides another processing cartridge, which differs from Embodiment Eleven in that the drive end of the component being tested 3 is located at one end of the developing cartridge, while the component being tested 30 is located at the other end of the developing cartridge. Power can be transmitted from the drive end of the developing cartridge to the component being tested 30 via telescopic movement or other means. Furthermore, the drive end has multiple protrusions, while the component being tested 30 has only one protrusion. A drive head on the developing cartridge provides rotational power to the developing roller 131, and simultaneously drives the powder feeding roller 440, the stirring frame 240, and the component being tested 3 via a series of transmission gear sets 45.

[0231] More details such as Figure 39 As shown in Embodiment Eleven, the fifth elastic element 185 is disposed at one end of the component being detected 3. Through the elastic action of the fifth elastic element 185, the third transmission rod 201 and the component being detected 3 reciprocate along the first axial direction. This enables the second detection protrusion 36 to trigger detection by the image forming apparatus.

[0232] Figures 40 to 41 The diagram shows a first state of operation of the component under test 3 in Embodiment Twelve, and a structural diagram of the position of the component under test 3 in conjunction with the detection device 7. In the first position, the tip of the second detection protrusion 36 of the component under test 3 contacts the detection device 7 in the first direction, thereby creating a certain gap between the component under test 3 and the detection device 7 in the first direction as observed in the diagram.

[0233] Figures 42 to 43 The diagram shows the second operating state of the component under test 3, and the structural diagram of the component under test 3 in conjunction with the detection device 7. In the second position, the non-point tip of the second detection protrusion 36 of the component under test 3 is in contact with the detection device 7. Figure 42 There is no gap between the first direction and the detection device 7.

[0234] Example 13

[0235] This embodiment provides another processing cartridge, which differs from Embodiment Twelve or Embodiment Eleven in that the drive end of the component being tested 3 is located at one end of the developing cartridge, while the component being tested 30 is located at the other end of the developing cartridge. Power can be transmitted from the drive end of the developing cartridge to the component being tested 30 by rotation. Furthermore, the drive end has multiple protrusions, while the component being tested 30 has only one protrusion. A drive head on the developing cartridge provides rotational power to the developing roller 131, and simultaneously, a series of transmission gear sets 45 drives the powder feeding roller 440, the stirring frame 240, and the component being tested 3.

[0236] Figure 44 The diagram shows the structure of the tested component 3 in embodiment thirteen. The second transmission rod 28 has a transmission protrusion 281, which is connected to 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 produce displacement in a first direction.

[0237] Specifically, as shown in the figure, the component being tested 3 can rotate along the second transmission rod 28. 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 extends freely to the position of the third rotating member 29, and can abut or detach from the rotating protrusion 290. A fifth elastic member 185 (preferably a torsion spring 190 structure) is provided near the transmission protrusion 282. When the third rotating member 29 receives external transmission power through the rotating tooth 294, the rotating protrusion 290 rotates around the rotating axis 296, and then interacts with the abutting transmission protrusion 282, driving the second transmission rod 28 to rotate, and then driving the component being tested 3 to rotate. The second detection protrusion 36 on the component being tested interacts with the detection device 7. Thus, the second detection protrusion 36 is triggered by the image forming device, and the first trigger state is output.

[0238] Figure 45 The diagram shows the second working position structure of the detected component 3 in Embodiment Thirteen. When the third rotating member 29 receives external transmission power through the rotating tooth 294, the rotating protrusion 290 rotates around the rotating shaft 296, and then interacts with the abutting transmission protrusion 282, driving the second transmission rod 28 to rotate, which in turn drives the detected component 3 to rotate, and the second detection protrusion 36 on the detected component 3 disengages. This achieves the detection triggering of the second detection protrusion 36 with the image forming apparatus, and then outputs a second trigger state.

[0239] Example 14

[0240] like Figures 46 to 60As shown, this embodiment discloses a developing apparatus that can be detachably mounted on a drum assembly in an image forming apparatus. The developing apparatus includes a housing 1, a developing assembly, a transmission assembly 2, a recognition assembly, a detection assembly 3, a power supply assembly, a first cover 111, and a second cover 121.

[0241] In the following descriptions of direction, perpendicular to Figure 46 When viewed from the direction of the middle paper, Figure 46 The left side of the middle page is left. Figure 46 The right side of the middle page is the right. Figure 46 The top of the middle paper is the upper part. Figure 46 The bottom of the middle paper is the lower side. Figure 46 The front side of the middle paper is the side closest to the front. Figure 46 The far side of the paper is the rear. The left-right direction is one embodiment of the first direction, the front-back direction is one embodiment of the second direction, and the up-down direction is one embodiment of the third direction.

The powder feeding roller 440 is located adjacent to the developing roller 131. The powder feeding roller 440 is closer to the fourth end 14 of the cartridge 1 than the developing roller 131. The stirring frame 240 is used to stir the developer within the receiving cavity to agitate the developer and prevent it from clumping.

[0244] A transmission assembly 2 is disposed at the first end 11. The transmission assembly 2 includes a drive unit rotatably mounted on the first end 11 of the housing 1, the rotation axis of the drive unit being parallel to a first direction. The drive unit includes a coaxially integrally formed drive gear and a drive force receiving device 4, the drive gear being closer to the housing 1 than the drive force receiving device 4 in the first direction. The drive force receiving device 4 is used to connect to the power output shaft on the image forming apparatus to receive the power output by the image forming apparatus.

[0245] The transmission assembly 2 also includes a developing gear 43, a powder feeding gear 44, a stirring gear set 24, a first idler wheel 471, a second idler wheel 472, a third idler wheel 473, and a fourth idler wheel 474. The developing gear 43 is coaxially fixedly mounted on one end of the developing roller 131 near the first end 11 of the cartridge body 1. The powder feeding gear 44 is coaxially fixedly mounted on one end of the powder feeding roller 440 near the first end 11 of the cartridge body 1. The stirring gear set 24 is coaxially fixedly mounted on one end of the stirring frame 240 near the first end 11 of the cartridge body 1. The stirring gear set 24 includes a large-diameter stirring gear set 24 and a small-diameter stirring gear set 24, with the small-diameter stirring gear set 24 being closer to the cartridge body 1 than the large-diameter stirring gear set 24 in a first direction.

[0246] The first idler wheel 471, the second idler wheel 472, the third idler wheel 473, and the fourth idler wheel 474 are all rotatably mounted on the first end 11 of the housing 1. The rotation axes of the first idler wheel 471, the second idler wheel 472, the third idler wheel 473, and the fourth idler wheel 474 are all parallel to a first direction. The first idler wheel 471 includes a large-diameter first idler wheel 471 and a small-diameter first idler wheel 471. In the first direction, the large-diameter first idler wheel 471 is closer to the housing 1 than the small-diameter first idler wheel 471. The fourth idler wheel 474 includes a grooved wheel 48 and a small-diameter fourth idler wheel 474. In the first direction, the grooved wheel 48 is farther from the housing 1 than the small-diameter fourth idler wheel 474. The diameter of the small-diameter fourth idler wheel 474 is smaller than the diameter of the grooved wheel 48.

[0247] The developing gear 43, the powder feeding gear 44, and the large-diameter first idler gear 471 all mesh with the drive gear. The large-diameter stirring gear set 24 meshes with the small-diameter first idler gear 471. The small-diameter stirring gear set 24 meshes with the second idler gear 472, the second idler gear 472 meshes with the third idler gear 473, and the third idler gear 473 meshes with the small-diameter fourth idler gear 474. The meshing can be direct or indirect.

[0248] The rotation axis of the drive unit is closer to the fifth end 15 and the fourth end 14 of the cartridge 1 than the rotation axis of the developing roller 131, and the rotation axis of the drive unit is closer to the third end 13 of the cartridge 1 than the rotation axis of the stirring frame 240.

[0249] The transmission assembly 2 also includes a third rotating member 29, the rotation axis of which is parallel to the first direction. A third bushing 299 is integrally formed coaxially on the third rotating member 29, and 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 bushing 299. Part of the third bushing 299 is located on the side of the third rotating member 29 away from the housing 1 in the first direction. Another part of the third bushing 299 is located on the side of the third rotating member 29 near the housing 1 in the first direction. An acceleration protrusion 297 is integrally formed on the third bushing 299, extending radially along the third rotating member 29, and has an arcuate surface. A second support shaft is integrally formed on the first end 11 of the housing 1. An acceleration member, a torsion spring 190, is mounted on the second support shaft, with one end of the torsion spring 190 being a fixed end and the other end being an acceleration end. A limiting protrusion is integrally formed on the first end 11 of the housing 1. A first bending portion is provided on the fixed end of the torsion spring 190. The limiting protrusion is used to block the movement of the first bending portion, thereby positioning the fixed end. The accelerating end of the torsion spring 190 extends to the side of the third rotating member 29 away from the housing 1. The accelerating end of the torsion spring 190 abuts against the outer surface of the third bushing 299. The accelerating end of the torsion spring 190 is integrally formed with a bending portion. The bending angle of the second bending portion is the same as the angle between the arc surface on the accelerating protrusion 297 and the circumferential surface of the third bushing 299. This allows the second bending portion to fit into the angle between the arc surface on the accelerating protrusion 297 and the circumferential surface of the third bushing 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 orientation of the developing cartridge.

[0250] The third rotating member 29 has a plurality of cylindrical pins 298 integrally formed on its end face away from the housing 1 in the first direction. In this embodiment, there are twenty-two cylindrical pins 298. The cylindrical pins 298 are evenly distributed along the circumferential direction. There is a notch 2971 between a pair of adjacent cylindrical pins 298. The interval between the two cylindrical pins 298 located on both sides of the notch 2971 is greater than the interval between other cylindrical pins 298 and their adjacent cylindrical pins 298. The notch 2971 is located on the third rotating member 29 on the side opposite to the acceleration protrusion 297 in the radial direction.

[0251] The third rotating member 29 has a first protrusion 291, a second protrusion 292, and a third protrusion 293 integrally formed on its end face near the box body 1 in the first direction. The first protrusion 291, the second protrusion 292, and the third protrusion 293 are all arranged circumferentially along the end face of the third rotating member 29 near the box body 1. The radially distant sides of the first protrusion 291, the second protrusion 292, and the third protrusion 293 are respectively the first contact surface, the second contact surface, and the third contact surface. The first contact surface, the second contact surface, and the third contact surface are all arc surfaces. The arc length corresponding to the first contact surface is longer than that of the second contact surface and the third contact surface.

[0252] This embodiment also includes a sixth elastic element 186. The transmission assembly 2 includes a second swing arm 202. A groove is integrally formed on the fifth end 15 of the box body 1, extending along a first direction. A pivot shaft 39 is integrally formed inside the groove along a third direction. The second swing arm 202 is rotatably mounted on the pivot shaft 39, and the rotation axis of the second swing arm 202 is parallel to the third direction. Both ends of the second swing arm 202 extend out of the groove. The end of the second swing arm 202 near the first end 11 of the box body 1 is the driven end, located on the movement trajectory of the first protrusion 291, the second protrusion 292, and the third protrusion 293. The end of the second swing arm 202 near the second end 12 of the box body 1 is the transmission end. The detection assembly 3 includes a second detection protrusion, which extends along a second direction and is integrally fixed to the transmission end of the second swing arm 202. In this embodiment, the front end of the second detection protrusion is the detection end 32. A support portion is integrally formed on the second lever 202, located between the second detected protrusion and the second end 12 of the housing 1. A mounting base 1221 is integrally formed on the second end 12 of the housing 1. One end of the sixth elastic member 186 is fixedly installed in the mounting base 1221, and the other end of the sixth elastic member 186 abuts against the support portion. A second cover 121 is fixedly installed on the second end 12 of the housing 1 by a snap or screw, and a guide rail 122 extending in the second direction is integrally formed on the second cover 121. The second detected protrusion is located in the guide rail 122 and can move along the extension direction of the guide rail 122. The end of the second detected protrusion closer to the developing roller 131 in the second direction is the detected end 32. The detected end 32 is used to trigger the detection device 7 in the image forming apparatus.

[0253] The component being tested, 3, has a first state and a second state.

[0254] In the first state, the second lever 202 forms an angle with the first direction, the sixth elastic member 186 is compressed, and the detected end 32 of the second detected protrusion pushes the detection device 7 within the image forming apparatus. The projection of the driven end of the second lever 202 in the third direction is located behind the projection of the rotation axis of the third rotating member 29 in the third direction.

[0255] In the second state, the second lever 202 is parallel to the first direction, the elastic potential energy of the sixth elastic element 186 is fully released, and the detected end 32 of the second detected protrusion does not contact the detection device 7 within the image forming apparatus. The detected end 32 in the second state is farther from the developing roller 131 in the second direction than the detected end 32 in the first state. The projection of the driven end of the second lever 202 in the third direction coincides with the projection of the rotation axis of the third rotating element 29 in the third direction.

[0256] The power supply assembly includes a conductive element located at the second end 12 of the housing 1. The conductive element has an electrical receiving surface 51 and also includes 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 feeding roller 440 near the second end 12 of the housing 1. The electrical receiving surface 51 is used to contact the power supply unit on the image forming apparatus to receive electrical energy output from the image forming apparatus and to transmit the electrical energy to the developing roller 131 and the powder feeding roller 440 to form a bias voltage between them. The electrical receiving surface 51 is located in the second direction between the rotation axis of the stirring frame 240 and the developing roller 131.

[0257] The identification component includes a storage medium and an electrical contact surface 5. The storage medium stores data, and the electrical contact surface 5 contacts and is electrically connected to the identification contacts within the image forming apparatus. The storage medium is fixedly mounted on the first cover 111, and the electrical contact surface 5 is fixedly mounted on and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end face of the storage medium. A third direction intersects with the electrical contact surface 5. In a second direction, 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, the distance between the electrical contact surface 5 and the rotation axis of the drive unit is less than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame 240.

[0258] The following is the operating process of the developing apparatus disclosed in this embodiment. The developing apparatus is installed onto the drum assembly within the image forming apparatus. The power output shaft of the image forming apparatus is connected to the drive force receiving device 4. The identification contact within the image forming apparatus contacts the electrical contact surface 5 and reads the information stored in the storage medium to identify information such as the model, capacity, and lifespan of the developing apparatus. 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 swing arm 202. At this time, the detected component 3 is in its 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 swing arm 202 to rotate to a state parallel to the first direction. Therefore, as the developing apparatus is installed into the drum assembly, it is touched and pushed by the detected end 32 of the second detected protrusion, causing the developing apparatus to be detected by the image forming apparatus.

[0259] Then the power output axis of the image forming apparatus drives the force receiving device 4 to output power, causing the drive unit to move along the axis of the image forming apparatus. Figure 28 It rotates clockwise. In the following description of the direction of rotation, clockwise or counterclockwise will be used... Figure 4 Based on the standard of 18, the drive gear rotates clockwise, causing the developing gear 43, the powder feeding gear 44, and the large-diameter first idler wheel 471 to rotate counterclockwise. The small-diameter first idler wheel 471 rotates counterclockwise together with the large-diameter first idler wheel 471, driving the large-diameter stirring gear set 24 to rotate clockwise. The small-diameter stirring gear set 24 rotates clockwise together with the large-diameter stirring gear set 24, driving the second idler wheel 472 to rotate counterclockwise. The second idler wheel 472 drives the third idler wheel 473 to rotate clockwise. The third idler wheel 473 drives the small-diameter fourth idler wheel 474 to rotate counterclockwise. The grooved wheel 48 rotates counterclockwise together with the small-diameter fourth idler wheel 474. The grooved wheel 48, through its engagement with the cylindrical pin 298 on the third rotating component 29, drives the third rotating component 29 to rotate clockwise at a first speed.

[0260] like Figure 5 Fourteen and Figure 5 As shown in Figure 15, when the third rotating member 29 is in its initial position, the first cylindrical pin 298 on the rear side of the notch 2971 engages with the grooved wheel 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 time, under the elastic force of the sixth elastic member 186, the second swing arm 202 moves to the second state, and the detected end 32 no longer pushes against the detection device 7 inside the image forming apparatus.

[0261] As the third rotating member 29 continues to rotate, the second protrusion 292 pushes the driven end, causing the driven end to contact the second contact surface of the second protrusion 292, thereby causing the detected component 3 to move to the first state, and the detected end 32 pushes the detected component 3 again.

[0262] 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 32 no longer pushes against the detection device 7 inside the image forming apparatus.

[0263] As the third rotating member 29 continues to rotate, the third protrusion 293 pushes the driven end, causing the driven end to contact 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 32 pushes the detection device 7 in the image forming apparatus again.

[0264] 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 32 no longer pushes against the detection device 7 inside the image forming apparatus.

[0265] As the third rotating member 29 continues to rotate, the acceleration protrusion 297 pushes the acceleration end of the torsion spring 190, causing the torsion spring 190 to undergo elastic deformation and accumulate elastic potential energy.

[0266] Then, the notch 2971 on the third rotating member 29 moves to the engagement position between the cylindrical pin 298 and the grooved wheel 48, preventing the cylindrical pin 298 from continuing to engage with the grooved wheel 48, and thus preventing the power of the grooved wheel 48 from being transmitted to the third rotating member 29. Simultaneously, the elastic potential energy stored in the torsion spring 190 is released, and the accelerating end of the torsion spring 190 pushes against the arc surface on the accelerating protrusion 297, causing the third rotating member 29 to rotate at a second speed faster than the first speed. This causes the first protrusion 291 to actuate the driven end at a faster speed; at this time, the speed at which the first protrusion 291 actuates the driven end is greater than the speed at which the second protrusion 292 and the third protrusion 293 actuate the driven end. This causes the detected component 3 to enter the first state, and the detected end 32 pushes against the detection device 7 within the image forming apparatus at a faster speed. This causes the speed detection component within the image forming apparatus to detect the increase in actuation speed.

[0267] The second bend on the acceleration end of the torsion spring 190 engages with the angle between the arc surface on the acceleration protrusion 297 and the third bushing 299, thereby positioning the third rotating member 29. 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.

[0268] By changing the number of protrusions on the third rotating member 29, different number of twisting operations can be achieved, thereby adapting to different image forming apparatuses. By changing the arc length or the ratio of the arc lengths of the first contact surface, the second contact surface, and the third contact surface of the third rotating member 29, the duration of the first state can be changed. By changing the arc length or the ratio of the arc lengths of the intervals between the first protrusion 291, the second protrusion 292, and the third protrusion 293, the duration of the second state can be changed.

[0269] Through the above design, the second end 12 of the cartridge 1 does not require any transmission components, which greatly reduces the volume of the second end 12 of the cartridge 1 and is conducive to the miniaturization of the developing device.

[0270] Example 15

[0271] Developing cartridges, such as Figures 61 to 70 As shown, it is installed in an image forming apparatus having a detection device 7, which includes: a housing 1, a power receiving device 4, a first moving rod 209, a transmission assembly 2, and a detection part 30, as detailed below:

[0272] like Figure 62 As shown, the housing 1 is used to store developer; the power receiving device 4 is disposed in the housing 1 and is able to receive driving force from the image forming apparatus.

[0273] The power receiving device 4 includes a drive gear and a stirring frame 240 gear, as detailed below:

[0274] A drive gear is disposed in the housing 1 and is capable of receiving driving force from the image forming apparatus. The drive gear is connected to the developing gear 43 and the powder feeding gear 44 respectively. The stirring rack 240 gear is disposed in the housing 1 and is connected to the drive gear. Thus, this solution provides a specific implementation of the power receiving device 4, which is compatible with this solution.

[0275] The first moving rod 209 is slidably connected to the box body 1; the box body 1 is provided with a first sliding groove 101, and the first moving rod 209 is slidably connected to the first sliding groove 101.

[0276] The transmission component 2 is connected to both the power receiving device 4 and the first moving rod 209, and can convert the rotational force of the power receiving device 4 into a pushing force on the first moving rod 209.

[0277] Among them, such as Figure 62 As shown, the transmission assembly 2 includes: a fourth rotating component 205, a first inclined push block 205a, and a second inclined push block 205b, as detailed below:

[0278] The fourth rotating component 205 is rotatably mounted on the housing 1 and is connected to the power receiving device 4 via a transmission.

[0279] The first inclined push block 205a is disposed on the fourth rotating member 205 and has a first inclined surface 205a1;

[0280] The second inclined push block 205b is disposed at the end of the first moving rod 209 and has a second inclined surface 205b1;

[0281] The first inclined surface 205a1 and the second inclined surface 205b1 are in contact and connected; preferably, in this embodiment, the inclination angle between the first inclined surface 205a1 and the second inclined surface 205b1 is an acute angle, preferably ~ degrees.

[0282] As a result, with the rotation of the fourth rotating member 205, the first inclined push block 205a pushes the second inclined push block 205b to slide, and causes the first moving rod 209 to slide in the direction (first direction) closer to the detected part 30.

[0283] Therefore, this solution provides a specific implementation method for converting the rotational force of the power receiving device 4 into a pushing force on the first moving rod 209. It can make full use of the rotational force of the power receiving device 4, and through the pushing force generated by the first inclined push block 205a squeezing the second inclined push block 205b when rotating, the first moving rod 209 can slide inside the box 1, and then push the detected part 30 to slide towards the detection device 7 (i.e., along the second direction forward) through the connecting rod 204.

[0284] In this embodiment, there are at least two first inclined push blocks 205a, which are evenly distributed on the fourth rotating member 205, and a first rotating notch 205d is formed between adjacent first inclined push blocks 205a. The first rotating notch 205d allows the first moving rod 209 to pass through, so that the connecting rod 204 drives the detected part 30 to slide away from the detection device 7; so that a detection electronic signal with a time interval is formed between the detected part 30 and the detection device 7. By varying the contact time between the detected part 30 and the detection device 7, electronic signals of different contact times are output, thereby completing the function of the developing cartridge being identified by the detection device 7 in the image forming apparatus.

[0285] The detection part 30 is slidably connected to the inner side of the housing 1 away from the power receiving device 4 (i.e., located on the non-drive side), and it can slide along the direction of approaching or moving away from the detection device 7 (i.e., the second direction); specifically, a second slide groove 102 is provided on the housing 1, and the detection part 30 is slidably connected in the second slide groove 102; thus, this solution provides a specific implementation of the first moving rod 209 and the detection part 30 being slidably connected on the housing 1.

[0286] The connecting rod 204 has one end rotatably connected to the first moving rod 209 and the other end rotatably connected to the part to be detected 30. Under the drive of the transmission assembly 2, the first moving rod 209 slides towards the part to be detected 30 (first direction), and the connecting rod 204 drives the part to be detected 30 to slide towards the detection device 7 (i.e., along the second direction forward).

[0287] like Figure 68 , Figure 69 , Figure 70 As shown, the seventh elastic element 187 is disposed in the housing 1 and connected to the first moving rod 209. It provides a restoring force to the first moving rod 209. Under the action of the seventh elastic element 187, the first moving rod 209 can slide away from the detected part 30, causing the connecting rod 204 to drive the detected part 30 to slide away from the detection device 7. In this embodiment, the seventh elastic element 187 is a spring.

[0288] When the power receiving device 4 continuously outputs rotational power in one direction, the first moving rod 209 of this scheme can reciprocate under the action of the seventh elastic member 187 through the first rotating notch 205d or the second rotating notch 205e, so as to convert it into the driving force output by the detected part 30 to the detection device 7 through the connecting rod 204, and then output an electronic signal with frequency.

[0289] The first moving rod 209 has a mounting groove 203b, 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, and the other end abuts against the mounting groove 203b. The mounting protrusion 203c can limit the sliding of the first moving rod 209 and can also support the seventh elastic member 187. This solution provides a specific implementation of the connection relationship between the seventh elastic member 187 and the first moving rod 209.

[0290] like Figure 65 , Figure 66 and Figure 67 As shown, in this embodiment, the connecting rod 204 includes: a rod body 204a, a first connecting part 204b, and a second connecting part 204c, as detailed below:

[0291] The first connecting part 204b has one end rotatably connected to the first moving rod 209 and the other end connected to the rod body 204a; the second connecting part 204c has one end connected to the rod body 204a and the other end rotatably connected to the part being tested 30. Therefore, this solution provides a specific structural configuration for the connecting rod 204, which is simple in structure and easy to manufacture. Specifically, the first connecting part 204b is hinged to the first moving rod 209, and the second connecting part 204c is hinged to the part being tested 30. This solution applies a hinged structure to the connection between the connecting rod 204 and the first moving rod 209 and the part being tested 30, which facilitates processing and production through its simple structure.

[0292] The end of the first moving rod 209 has a rotating groove 203a, and the first connecting part 204b is rotatably connected within the rotating groove 203a. This solution provides a specific setting position for the first connecting part 204b to be rotatably connected to the first moving rod 209.

[0293] Work process:

[0294] like Figure 67 As shown, the power receiving device 4 transmits rotational power to the fourth rotating member 205 and makes it rotate. As the fourth rotating member 205 rotates, the first inclined push block 205a applies a pushing force to the second inclined push block 205b. After being pushed, the second inclined push block 205b drives the first moving rod 209 to slide towards the detected part 30 (i.e., the first direction). As the first moving rod 209 slides, it compresses the seventh elastic member 187 and makes the seventh elastic member 187 elastic. The connecting rod 204 rotates and drives the detected part 30 to slide towards the detection device 7 (i.e., along the second direction forward). At this time, the detected part 30 applies pressure to the detection device 7, and the detection device 7 enters the detection state after being pressed.

[0295] like Figure 66 As shown, as the fourth rotating member 205 rotates, when the second inclined push block 205b on the first moving rod 209 rotates to the first rotating recess 205d, under the action of the seventh elastic member 187, the first moving rod 209 slides to the right along the first direction, the second inclined push block 205b slides in the first rotating recess 205d, the connecting rod 204 rotates and drives the detected part 30 to slide away from the detection device 7 (i.e., along the second direction backward). At this time, the detected part 30 no longer applies pressure to the detection device 7, and the detection device 7 exits from the detection state.

[0296] In this embodiment, the detection device 7 is able to rotate, so the detected part 30 and the detection device 7 are always in contact. However, it is not limited to this. The detection device 7 can also be fixed and switch the detection state by receiving the pressure applied by the detected part 30.

[0297] Example 16

[0298] The difference between Embodiment 16 and Embodiment 13 is that, in addition to the first inclined push block 205a, the transmission assembly 2 also includes a third inclined push block 205c.

[0299] Specifically, transmission assembly 2 also includes:

[0300] The third inclined push block 205c is disposed on the fourth rotating member 205 and has a third inclined surface 205c1;

[0301] A second rotating notch 205e is formed between the first inclined push block 205a and the third inclined push block 205c.

[0302] The first inclined push block 205a and the third inclined push block 205c have different circumferences on the fourth rotating member 205, which makes the length of the second rotating notch 205e between them different, thereby enabling the output of electronic signals with different contact times to adapt to different types of developing cartridges.

[0303] 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, resulting in a faster movement speed for the first moving rod 209 when driven by the third inclined surface 205c1. This, in turn, causes the detected part 30 to move at a faster speed when it touches the detection device 7, enabling the detection device 7 to detect that the detected part 30 has touched the detection device 7 at a faster speed and generate an electrical signal.

[0304] In other embodiments, by changing the tilt angles of the first inclined surface 205a1, the second inclined surface 205b1, and the third inclined surface 205c1, the moving speed of the first moving rod 209 when driven by the first inclined surface 205a1, the second inclined surface 205b1, and the third inclined surface 205c1 can be changed. By setting different tilt angles for the first inclined surface 205a1, the second inclined surface 205b1, and the third inclined surface 205c1, the first moving rod 209 can have multiple moving speeds. By setting the ratio of the tilt angles of the first inclined surface 205a1, the second inclined surface 205b1, and the third inclined surface 205c1, the ratio between the different moving speeds of the first moving rod 209 can be set.

[0305] Beneficial effects

[0306] Since the existing detection unit 30 is driven by the power receiving device 4, the detection device 7 and the detection unit 30 are generally located beside the power receiving device 4. However, this solution provides a specific implementation in which the detection unit 30 and the detection device 7 are located in the housing 1 away from the power receiving device 4 through the combination of the first moving rod 209, the transmission component 2 and the connecting rod 204. In this solution, the detection unit 30 and the detection device 7 are in contact connection, which does not require complicated operation or structure to disconnect the connection between the detection unit 30 and the detection device 7. Therefore, it can solve the problem of inconvenient operation caused by installing or removing the device into the image forming apparatus. At the same time, it can effectively solve the problem of the developing cartridge being difficult to identify due to the complex connection relationship between the detection unit 30 and the detection device 7, so as to ensure the normal operation of the developing cartridge.

[0307] Example 17

[0308] like Figures 98 to 101 As shown, the difference between this embodiment and embodiment thirteen is that the first moving rod 209 is cylindrical. In this embodiment, the mounting groove 203b and the rotating groove 203a may not be provided on the first moving rod 209. The first sliding groove 101 includes a first segment 101a and a second segment 101b that are connected in the first direction. The first segment 101a is closer to the transmission component 2 in the first direction than the second segment 101b. A positioning part 101b1 is provided in the second segment 101b. In this embodiment, there are two positioning parts 101b1. The positioning part 101b1 has a positioning hole with a shape and size that matches the cross-section of the first moving rod 209. The first moving rod 209 is slidably installed in the positioning hole. A driven component 209c is fixedly installed at the end of the first moving rod 209 that is closer to the transmission component 2 in the first direction. The driven component can be fixedly installed on the first moving rod 209 by means of threaded connection, screw connection, snap-fit, etc. The driven member 209c has an integrally formed driven protrusion 209c1 protruding along the first direction at one end near the transmission assembly 2. The driven protrusion 209c1 has an integrally formed arc surface, which makes the contact between the driven protrusion 209c1 and the first inclined push block 205a and the second inclined push block 205b smoother. The driven member 209c is slidably mounted within the first segment 101a, and the dimension of the first segment 101a in the second direction is larger than the dimension of the second segment 101b in the second direction. The seventh elastic member 187 is sleeved on the portion of the first moving rod 209 located within the first segment 101a, with one end abutting against the driving member and the other end abutting against the positioning part 101b1.

[0309] A transmission component 209a is fixedly mounted on the end of the first moving rod 209 away from the transmission assembly 2 in the first direction. The transmission component 209a is fixedly mounted on the first moving rod 209 by means of threaded connection, screw connection, snap-fit, etc. A first pin 209b extending along the +Z axis direction is integrally formed on the transmission component 209a.

[0310] In this embodiment, the connecting rod 204 is omitted. The detection part 30 in this embodiment includes a first part 371, a second part 372, and a third part 373. The first part 371 is parallel to the second part. A pivot groove 3711 is integrally formed at the end of the first part 371 near the first moving rod 209 in the second direction. The pivot groove 3711 opens rearward in the second direction. The first pin 209b is inserted into the pivot groove 3711, which can rotate and slide relative to the pivot groove 3711. A second pin 3712 extending in the third direction is integrally formed at the end of the first part 371 away from the first moving rod 209 in the second direction. A pivot seat 17 is integrally formed on the housing 1 and is fixed to the housing 1. The second pin 3712 is rotatably connected to the pivot seat 17. The second part 372 is integrally formed with the end of the first part 371 away from the first moving rod 209 in the second direction. The second part 372 and the first part 371 form a 90-degree angle. The second part 372 is integrally connected to the third part 373 at the end furthest from the first part 371 in the first direction. The end of the third part 373 furthest from the second part 372 in the second direction is the end to be detected 32. The third part 373 and the second part 372 form a 70-degree angle.

[0311] The difference between the working process of this embodiment and that of Embodiment Thirteen is that when the first moving rod 209 is pushed by the first inclined push block 205a or the second inclined push block 205b, the first inclined push block 205a or the second inclined push block 205b acts on the arc surface of the driven protrusion 209c1, making the process of pushing the first moving rod 209 smoother. After the first moving rod 209 moves along the first direction, the seventh elastic element 187 is compressed, and the transmission element 209a on the first moving rod 209 pushes the pivot groove 3711 along the first direction through the first pin 209b, causing the first part 371 to swing counterclockwise around the second pin 3712 (to... Figure 1 (The viewing angle is 100). This causes the detected end 32 to swing counterclockwise, thereby pushing the detection device 7 inside the image forming apparatus.

[0312] By adopting the design in this embodiment, the assembly of the first moving rod 209 and the transmission component 209a is simpler, the structure is simpler, and the transmission is more stable.

[0313] Example 18

[0314] For example, 103 to Figure 104As shown, the difference between this embodiment and Embodiment Seventeen is that, in this embodiment, the fourth rotating component 205 is further provided with a fourth inclined push block 205f and a fifth inclined push block 205g, and the fourth inclined push block 205f and the fifth inclined push block 205g are respectively provided with a fourth inclined surface 205f1 and a fifth inclined surface 205g1. The first inclined push block, the third inclined push block, the fourth inclined push block 205f, and the fifth inclined push block 205g are arranged sequentially along the circumferential direction on one end face of the fourth rotating component 205 near the box body. The angle θ1 between the first inclined surface 205a1 and the end face of the fourth rotating component 205 is 50°. The angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, the fifth inclined surface 205g11 and the end face of the fourth rotating component 205 is 35°.

[0315] In other embodiments of this technical solution, the included 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 included 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 and does not affect the implementation of the technical solution.

[0316] When the first inclined plane 205a1 drives the first moving rod 209, the first moving rod 209 moves at a speed of V2 in the first direction. When the third inclined plane 205c1, the fourth inclined plane 205f1, and the fifth inclined plane 205g1 drive the first moving rod 209, the first moving rod 209 moves at a speed of V2 in the first direction. Since the angle θ1 between the first inclined plane 205a1 and the end face of the fourth rotating member 205 is greater than the angle θ2 between the third inclined plane 205c1, the fourth inclined plane 205f1, and the fifth inclined plane 205g1 and the end face of the fourth rotating member 205, and the rotational speed of the fourth rotating member 205 is a fixed value, V1 is greater than V2. This allows the telescopic rod to touch the detection device inside the image forming apparatus once at a speed of V1, and then touch the detection device three times at a speed of V2 when the fourth rotating member 205 rotates. This enables the image forming apparatus to identify the developing cartridge not only based on the number of times the detection device 1 is touched, but also based on the speed at which the detection device 1 is touched.

[0317] Compared to detection based solely on the number of touches, combining touch speed and the number of touches increases the dimension of detectable information. The image forming apparatus can identify more types of developing cartridges based on the combination of touch speed and touch count information, improving versatility. Furthermore, the transmission is achieved through the fourth rotating component 205 and the inclined plane, resulting in a simple structure, stable transmission, low manufacturing difficulty, and low cost, making it suitable for mass production.

[0318] Example 19

[0319] like Figures 103 to 104 As shown, the difference between this embodiment and Embodiment 18 is that the included angle θ1 between the first inclined surface 205a1 and the end face of the fourth rotating member 205 is 60°. The included angle θ2 between the third inclined surface 205c1, the fourth inclined surface 205f1, and the fifth inclined surface 205g1 and the end face of the fourth rotating member 205 is 40°. In this embodiment, the included angles between the first inclined surface 205a1, 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 are changed. This changes the values ​​of V1 and V2, allowing the detection device 1 of the image forming apparatus to detect different types of developing cartridges when touched at different speeds, thereby improving applicability and ensuring the stability of the transmission, preventing jamming due to excessively large included angles.

[0320] Example 20

[0321] like Figures 103 to 104 As shown, the difference between this embodiment and Embodiment 18 is that the included angle θ1 between the first inclined plane 205a1 and the end face of the fourth rotating member 205 is 70°. The included angle θ2 between the third inclined plane 205c1, the fourth inclined plane 205f1, the fifth inclined plane 205g1 and the end face of the fourth rotating member 205 is 50°. In this embodiment, the included angles between the first inclined plane 205a1, the third inclined plane 205c1, the fourth inclined plane 205f1, the fifth inclined plane 205g1 and the end face of the fourth rotating member 205 are changed. This changes the values ​​of V1 and V2, allowing the detection device of the image forming apparatus to detect different types of developing cartridges when touched at different speeds, thereby improving applicability. At the same time, increasing the included angle to its maximum value, while ensuring transmission stability, widens the range of selectable included angles, thereby increasing the number of detectable types. This improves applicability and versatility.

[0322] Example 21

[0323] like Figures 18 to 28As shown, the difference between this embodiment and Embodiment Fifteen is that a first positioning protrusion 205a2 and a second positioning protrusion 205a3 are integrally formed on the side of the first inclined push block 205a near 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, and there is 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 sides of the first positioning protrusion 205a2 and the second positioning protrusion 205a3 closest to the housing 1 are both arc surfaces, so that the contact between the first positioning protrusion 205a2 and the second positioning protrusion 205a3 and the driven protrusion 209c1 is smoother, and so that when the first positioning protrusion 205a2 and the second positioning protrusion 205a3 move in a circular motion together with the fourth rotating member 205, the first positioning protrusion 205a2 and the second positioning protrusion 205a2 can apply a force to the driven protrusion 209c1 in the left direction.

[0324] In this embodiment, an incomplete gear 205h is integrally formed coaxially on the fourth rotating component 205. The fourth rotating component 205 receives power transmitted from the power receiving device 4 through gear transmission. In other embodiments, transmission can also be achieved through non-gear methods such as friction transmission or belt transmission.

[0325] A first cover 111 is also installed on the first end 11 of the housing 1. The first cover 111 is used to protect the transmission device and the power receiving device 4. The first cover 111 is detachably fixed to the housing 1 by screws or buckles. The first cover 111 has an opening, through which the incomplete gear 205h is exposed. The first scale 111a and the second scale 111b are integrally formed on the first cover 111 at the opening. The incomplete gear 205h has an integrally formed marking portion 205h1. When the marking portion 205h1 is aligned with the first scale 111a, the incomplete gear 205h disengages and stops receiving power, and the fourth rotating member 205 stops rotating. When the marking portion 205h1 is aligned 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.

[0326] The specific working process of the developing cartridge in this embodiment will be described next. Parts identical to those in Embodiments 3 and 1 will be omitted. As the fourth rotating member 205 rotates along the rotation direction J, the first positioning protrusion 205a2 rotates to a position contacting the driven protrusion 209c1 and applies a force to the driven protrusion 209c1 in the left direction, causing the first moving rod 209 to move in the left direction, and the driven protrusion 209c1 to avoid the first positioning protrusion 205a2. After the first positioning protrusion 205a2 passes the driven protrusion 209c1, the first moving rod 209 moves to the right direction and resets under the action of the elastic member. At this time, the driven protrusion 209c1 is located between the first positioning protrusion 205a2 and the second positioning protrusion 205a3. When the marking part 205h1 aligns with the first scale 111a, the incomplete gear 205h disengages and stops receiving power, and the fourth rotating member 205 stops 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 housing 1, the first positioning protrusion 205a2 and the second positioning protrusion 205a3 abut against the driven protrusion 209c1. The first positioning protrusion 205a2 and the second positioning protrusion 205a3 need to overcome the elastic force of the elastic member to continue rotating, thereby preventing the fourth rotating member 205 from producing unexpected movement. This achieves the positioning effect of the fourth rotating member 205 after the incomplete gear 205h disengages, preventing the fourth rotating member 205 from producing unexpected movement and causing the incomplete gear 205h to misengage, thereby causing the detected end to produce unexpected movement, and thus causing the detected end to accidentally touch the detection device in the image forming apparatus.

[0327] When the fourth rotating member 205 needs to be reset, the user only needs to manually rotate the fourth rotating member 205 along the rotation direction J of the fourth rotating member 205. This will cause the second positioning protrusion 205a3 to overcome the elastic force of the elastic member and push the driven end, thereby causing the fourth rotating member 205 to rotate to the position where the marking part 205h1 is aligned with the second scale 111b. At this time, the incomplete gear 205h re-enters the meshing state and can receive the power transmitted by the power receiving device 4 to rotate.

[0328] Example 22

[0329] like Figures 71 to 96 As shown, this embodiment discloses a developing apparatus that can be detachably mounted on a drum assembly in an image forming apparatus. The developing apparatus includes a housing 1, a developing assembly, a transmission assembly 2, a recognition assembly, a detection assembly 3, a power supply assembly, a first cover 111, and a second cover 121.

The powder feeding roller 440 is located adjacent to the developing roller 131. The powder feeding roller 440 is closer to the fourth end 14 of the cartridge 1 than the developing roller 131. The stirring frame 240 is used to stir the developer within the receiving cavity to agitate the developer and prevent it from clumping.

[0332] The transmission assembly 2 is disposed at the first end 11. The transmission assembly 2 includes a drive unit rotatably mounted on the first end 11 of the housing 1, and the rotation axis of the drive unit is parallel to a first direction. The drive unit includes a coaxially integrally formed drive gear and a power receiving unit, and the drive gear is closer to the first end 11 of the housing 1 in the first direction than the power receiving unit. The power receiving unit is used to connect to the power output shaft on the image forming apparatus to receive the power output by the image forming apparatus.

[0333] The transmission assembly 2 also includes a developing gear 43, a powder feeding gear 44, a stirring gear set 24, and a first idler wheel 471. The developing gear 43 is coaxially fixedly mounted on one end of the developing roller 131 near the first end 11 of the cartridge body 1. The powder feeding gear 44 is coaxially fixedly mounted on one end of the powder feeding roller 440 near the first end 11 of the cartridge body 1. The stirring gear set 24 is coaxially fixedly mounted on one end of the stirring frame 240 near the first end 11 of the cartridge body 1. A support column is integrally formed on the first end 11 of the cartridge body 1 along a first direction. The first idler wheel 471 is rotatably mounted on the support column. The rotation axis of the first idler wheel 471 is parallel to the first direction. The first idler wheel 471 includes a large-diameter first idler wheel 471 and a small-diameter first idler wheel 471. In the first direction, the large-diameter first idler wheel 471 is closer to the first end 11 of the cartridge body 1 than the small-diameter first idler wheel 471.

[0334] The developing gear 43, the powder feeding gear 44, and the large-diameter first idler gear 471 all mesh with the drive gear. The stirring gear assembly 24 meshes with the small-diameter first idler gear 471. The meshing can be direct or indirect.

[0335] The rotation axis of the drive unit is closer to the fifth end 15 and the fourth end 14 of the cartridge 1 than the rotation axis of the developing roller 131, and the rotation axis of the drive unit is closer to the third end 13 of the cartridge 1 than the rotation axis of the stirring frame 240.

[0336] The component to be tested 3 includes a first slider 207a, a second slider 207b, a fifth rotating component 206, a sixth rotating component 208a, and a grooved wheel 48. The first slider 207a is the component to be tested. The grooved wheel 48 is coaxially fixedly mounted on one end of the stirring frame 240 located at the second end 12 of the box body 1. The fifth rotating component 206 is rotatably mounted on the second end 12 of the box body 1, and the rotation axis 296 of the fifth rotating component 206 is parallel to the first direction. On the surface of the fifth rotating component 206 near the second end 12 of the box body 1 in the first direction, a plurality of cylindrical pins 298 are integrally formed, distributed along the circumference of the fifth rotating component 206. 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 grooved wheel 48. The fifth rotating component 206 has a fifth protrusion 381 and a sixth protrusion 382 integrally formed on its surface away from the second end 12 of the housing 1 in the first direction. The sides of the fifth protrusion 381 and the sixth protrusion 382 that are radially away from the rotation axis 296 of the fifth rotating component 206 are respectively the fourth contact surface and the fifth contact surface. Both the fourth and fifth contact surfaces are arc surfaces, and their radii (i.e., the distance from the side of the fourth and fifth contact surfaces radially away from the axis of the fifth rotating component 206 to the axis of the fifth rotating component 206) are equal. A seventh protrusion 383 is integrally formed on the circumferential surface of the fifth rotating component 206, protruding radially from the circumferential surface of the fifth rotating component 206. The distance from the side of the seventh protrusion 383 radially away from the rotation axis 296 of the fifth rotating component 206 to the rotation axis 296 of the fifth rotating component 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.

[0337] A guide rail 122 is integrally formed on the second cover 121 along the second direction. The first slider 207a and the second slider 207b are both 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 closest to the developing roller 131 in the second direction is the detection end 32. A support seat extending along the first direction is integrally formed within the guide rail 122. A mounting recess 207c is formed on the first slider 207a, and the support seat extends into the mounting recess 207c. An eighth elastic element 188 is mounted between the support seat and the sidewall of the mounting recess 207c. The eighth elastic element 188 is used to reset the first slider 207a. A second lever 207a1 is integrally formed on the first slider 207a, and part of the second lever 207a1 is located within the movement trajectory of the fifth protrusion 381 and the sixth protrusion 382.

[0338] A support plate 121a is integrally formed at the end of the slide rail away from the developing roller 131 in the second direction, and an opening for the probe end 32 to extend from the end of the slide rail near the developing roller 131 in the second direction. A support base 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. The end of the mounting groove near the support plate 121a is not closed. A ninth elastic member 189 is installed in the mounting groove. One end of the ninth elastic member 189 abuts 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 abuts 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 opened on the second slider 207b, located on the lower side wall of the mounting groove. A second limiting opening 121c is opened inside the slide rail. The second limiting opening 121c is located inside the slide rail between the support base and the support plate 121a. The second slider 207b has a first limiting protrusion 207b1 integrally formed at one end near the support plate 121a, and a second limiting protrusion 207b2 that matches the first limiting protrusion is integrally formed on the slide groove.

[0339] A sixth rotating component 208a is rotatably mounted on the second cover 121. The rotation axis of the sixth rotating component 208a is parallel to the first direction. The sixth rotating component 208a is located below the second limiting port and is cylindrical. A third limiting protrusion 207b3 is integrally formed on the circumferential surface of the sixth rotating component 208a. A driven protrusion 209c1 is also integrally formed on the circumferential surface of the sixth rotating component 208a, and the driven protrusion 209c1 is located within the movement trajectory of the seventh protrusion 383. A reset arm 331 is integrally formed on the circumferential surface of the sixth rotating component 208a. A stop block 33 is integrally formed at the end of the reset arm 331 away from the sixth rotating component 208a. A reset port for the reset arm 331 to extend is opened on the second cover 121. The size of the reset port is smaller than the size of the stop block 33, so that the stop block cannot pass through the reset port.

[0340] The sixth rotating component 208a, the second slider 207b, and the ninth elastic component 189 constitute the speed change assembly 208.

[0341] The first slider 207a has a third state and a fourth state.

[0342] In the third state, the detected end 32 of the first slider 207a extends out of the groove, and the eighth elastic element 188 is compressed.

[0343] In the fourth state, the detected end 32 of the first slider 207a is farther away from the developing roller 131 than in the third state, and the eighth elastic element 188 does not undergo elastic deformation.

[0344] The power supply assembly includes a conductive element located at the second end 12 of the housing 1. The conductive element has an electrical receiving surface 51 and also includes 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 feeding roller 440 near the second end 12 of the housing 1. The electrical receiving surface 51 is used to contact the power supply unit on the image forming apparatus to receive electrical energy output from the image forming apparatus and to transmit the electrical energy to the developing roller 131 and the powder feeding roller 440 to form a bias voltage between them. The electrical receiving surface 51 is located in the second direction between the rotation axis of the stirring frame 240 and the developing roller 131.

[0345] The identification component includes a storage medium and an electrical contact surface 5. The storage medium stores data, and the electrical contact surface 5 contacts and is electrically connected to the identification contacts within the image forming apparatus. The storage medium is fixedly mounted on the first cover 111, and the electrical contact surface 5 is fixedly mounted on and electrically connected to the storage medium. The electrical contact surface 5 is mounted on the lower end face of the storage medium. A third direction intersects with the electrical contact surface 5. In a second direction, 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, the distance between the electrical contact surface 5 and the rotation axis of the drive unit is less than the distance between the electrical contact surface 5 and the rotation axis of the stirring frame 240.

[0346] The following describes the operation of the developing apparatus disclosed in this embodiment. The developing apparatus is installed onto the drum assembly within the image forming apparatus. The power output shaft of the image forming apparatus is connected to the power receiving unit. The identification contact within the image forming apparatus contacts the electrical contact surface 5 and reads the information stored in the storage medium to identify information such as the model, capacity, and lifespan of the developing apparatus.

[0347] The developing apparatus disclosed in this embodiment has a factory-preset state. In the factory-preset state, the component being tested 3 is in a third state, the second lever 207a1 is in contact with and limited by the fourth contact surface, so that the first slider 207a remains in the third state and cannot be reset by the action of the eighth elastic member 188. At the same time, the first limiting port 121b and the second limiting port 121c are in an aligned position, the ninth elastic member 189 is in a compressed state, the third limiting protrusion 207b3 is inserted into the first limiting port 121b and the second limiting port 121c, and the third limiting protrusion 207b3 abuts against the side wall of the second limiting port 121c on the side away from the support plate 121a in the second direction. This causes the second slider 207b to be stuck and limited by the third limiting protrusion 207b3, so that the elastic potential energy of the ninth elastic member 189 cannot be released.

[0348] When the developing device is installed onto the drum assembly in the image forming apparatus, the detected end 32 on the developing device in its initial state is in the extended slide rail state. Therefore, as the developing device is installed into the drum assembly, the detected end 32 will push the detector in the image forming apparatus for the first time, causing the detector to generate an electrical signal, thereby enabling the image forming apparatus to detect that the developing device has been installed.

[0349] When the image forming apparatus receives a print command, it begins to output power to the power receiving unit, causing the power receiving unit to rotate... Figure 7 The fifteenth middle school rotates clockwise (the direction of rotation in this paragraph is always indicated by...). Figure 7(Based on the observation angle of 15), the drive gear rotates together with the power receiving unit, causing the developing gear 43, the powder feeding gear 44, and the large-diameter first idler wheel 471 to rotate counterclockwise. The small-diameter first idler wheel 471 rotates counterclockwise together with the large-diameter first idler wheel 471. The small-diameter first idler wheel 471 drives the stirring gear set 24 to rotate clockwise. This causes the developing roller 131, the powder feeding roller 440, and the stirring frame 240 to start operating.

[0350] At the same time, the stirring rack 240 drives the groove wheel 48 to rotate. Figure 7 The thirteenth rotates counterclockwise (the direction of rotation in the following description is always based on...). Figure 7 Based on the observation angle of the thirteenth, since the grooved wheel 48 is engaged with the cylindrical pin 298, the grooved wheel 48 drives the fifth rotating component 206 to rotate through the cylindrical pin 298.

[0351] As the fifth rotating member 206 rotates, after the fifth protrusion 381 disengages from the second lever 207a1, the fourth contact surface no longer abuts against the second lever 207a1, thus losing its 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, at which point the detected end 32 no longer pushes the detection member.

[0352] Then, as the fifth rotating member 206 rotates, the sixth protrusion 382 contacts the second lever 207a1. The sixth protrusion 382 pushes the second lever 207a1 to move along the second direction toward the developing roller 131, so that the first slider 207a moves to the third state again, and the detected end 32 pushes the detection member for the second time.

[0353] Then, as the fifth rotating member 206 rotates, the sixth protrusion 382 no longer contacts 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.

[0354] Then, as the fifth rotating member 206 rotates, the seventh protrusion 383 actuates the driven protrusion 209c1, thereby causing the sixth rotating member 208a to rotate counterclockwise. This causes the sixth rotating member 208a to drive the third limiting protrusion 207b3 to rotate counterclockwise, causing the third limiting protrusion 207b3 to move out from the first limiting port 121b and the second limiting port 121c. This removes the second slider 207b from the third limiting protrusion 207b3, releasing the elastic potential energy accumulated in the ninth elastic member 189. Under the elastic force of the ninth elastic member 189, the second slider 207b moves along the slide rail to the position where the first and second limiting protrusions abut. During the movement of the second slider 207b, it impacts the first slider 207a, causing the first slider 207a to move back to the third state and be pushed against the detection member for the third time by the detection end 32. Simultaneously, because 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 element 188 cannot overcome the elastic force of the ninth elastic element 189, preventing the first slider 207a from resetting. This keeps the first slider 207a in the third state, with the detected end 32 continuously pushing the detection element. Simultaneously, the fifth protrusion 381 and the sixth protrusion 382 can no longer activate the second lever 207a1, thus completing the detection process.

[0355] Furthermore, by selecting a ninth elastic element 189 with a larger elastic modulus, 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. Optionally, a ninth elastic element 189 with a smaller elastic modulus can also be selected, so that the second speed is less than the first speed. Through the above design, the first slider 207a can have different movement speeds, and the image forming apparatus can detect the change in the movement speed of the first slider 207a, thereby detecting information from the developing apparatus.

[0356] Through the above process, the image forming apparatus can detect the number of times the 32 pairs of detection elements are pushed, the duration of the push, the interval duration, the push speed, and other information. Different permutations and combinations of the above information correspond to different information about the developing apparatus (such as different models, different capacities, newness, etc.).

[0357] As the sixth rotating component 208a rotates, it drives the reset arm to perform a circular motion, causing the reset arm to move the stop 33 towards the second cover 121. When it is necessary to reset the tested component 3, simply rotate the sixth rotating component 208a to its initial position, then press the second slider 207b into the slide rail, aligning the first limiting port 121b and the second limiting port 121c. Then pull the stop 33, causing the reset arm to pull the sixth rotating component 208a to rotate. The sixth rotating component 208a drives the third limiting protrusion 207b3 to re-engage within the first limiting port 121b and the second limiting port 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 component 208a is rotated by the seventh protrusion 383, the reset arm undergoes elastic deformation, accumulating elastic potential energy. When the first limiting port 121b aligns with the second limiting port 121c, the sixth rotating component 208a automatically rotates under the elastic action of the reset arm, causing the third limiting protrusion 207b3 to automatically engage with the first limiting port 121b and the second limiting port 121c, thus completing the reset.

[0358] Because the central angle subtended by the fifth protrusion 381 is larger than that 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 duration of the first slider 207a remaining in the third state can be altered by changing the size of the central angles subtended by the fifth and sixth protrusions 381 and 382. The number of times the first slider 207a enters the third state can be changed by increasing the number of protrusions. The arrangement order of the fifth, sixth, and seventh protrusions 381 and 382 can also be changed according to actual needs.

[0359] By adopting the above structure, the difficulty of resetting the tested component 3 can be greatly reduced, the user's ease of use can be improved, and the ease of factory debugging can be enhanced.

[0360] Example 23

[0361] like Figures 90 to 92As shown, the difference between this embodiment and embodiment twenty-two is that, in this embodiment, the transmission assembly 208 omits the sixth rotating member 208a, the second slider 207b, and the ninth elastic member 189, and includes a tenth elastic member 191. The tenth elastic member 191 is a torsion spring 190. The tenth elastic member 191 includes a main body 191a formed by winding metal wire in a ring. A fixed arm 191b is integrally formed at the left end of the main body 191a, and an action part 191c is integrally formed at the right end of the main body 191a. The action part 191c includes a force-receiving part 191d and a force-applying part 191e, with the force-applying part 191e being longer than the force-receiving part 191d.

[0362] The first cover 111 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 to the right from the right surface of the first 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 fixing arm 191b extends into the first limiting portion 111f and is limited by the first limiting portion 111f. The second limiting portion 111g is arc-shaped groove-shaped, and the part of the main body 191a closest to the second cover 121 is inserted into 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 does not undergo elastic deformation. A positioning post 21b protruding to the right is integrally formed on the second cover 121 within the area enclosed by the first support part 111d, the second support part 111e, and the second limiting part 111g. The main body 191a is fitted onto the positioning post 21b. In the factory-preset state, the force-applying part 191e abuts against the right end of the first support part 111d, and the force-receiving part 191d abuts against the right end of the second support part 111e. At the same time, because the second limiting part 111g locks and positions the main body 191a close to the second cover 121, the main body 191a is in a stretched state at this time.

[0363] In this embodiment, the seventh protrusion 383 protrudes to the left from the left end face of the fifth rotating member 206 along the axial direction of the fifth rotating member 206. The seventh protrusion 383 is larger in the first direction than the fifth protrusion 381 and the sixth protrusion 382. That is, the left end of the seventh protrusion 383 is farther from the housing 1 than the left ends of the fifth protrusion 381 and the sixth protrusion 382. This ensures that only the seventh protrusion 383 can touch the force-receiving part 191d, while the fifth protrusion 381 and the sixth protrusion 382 cannot touch the force-receiving part 191d. In this embodiment, the radius of the side of the seventh protrusion 383 that is radially away from the rotation axis 296 of the fifth rotating member 206 is equal to the radius of the fourth contact surface and the fifth contact surface.

[0364] In this embodiment, the specific working process differs from that in Embodiment 22 in that, as the fifth rotating member 206 rotates, the seventh protrusion 383 pushes the force-receiving part 191d, causing the main body 191a to twist, thereby causing the force-receiving part 191d to swing counterclockwise around the main body 191a. Figure 91 (From a certain perspective), the force-applying part 191e is then driven by the force-receiving part 191d to swing counterclockwise around the main body 191a. Figure 91 (Perspective). Since the force-applying part 191e is longer than the force-receiving part 191d, the linear velocity of the end of the force-receiving part 191d during its swing is less than the linear velocity of the force-applying part 191e during its swing. Furthermore, since the force-receiving part 191d is driven to move by the seventh protrusion 383, the linear velocity of the force-receiving part 191d is equal to the linear velocity of the seventh protrusion 383. Therefore, the linear velocity of the force-applying part 191e is greater than the linear velocity of the seventh protrusion 383. During the counterclockwise swing of the force-applying part 191e, the second lever 207a1 is moved forward (…). Figure 91 (View angle), causing the second lever 207a1 to move forward at a second speed, and driving the first slider 207a to push the detector inside the image forming apparatus at a second speed.

[0365] As the force-receiving part 191d and the force-applying part 191e swing, when the force-applying part 191e swings to a position where it no longer abuts against the first support part 111d, the force-receiving part 191d also swings to a position where it no longer abuts against the second support part 111e. At this time, the main body 191a begins to contract. Under the action of the elastic force of the main body 191a, the force-receiving part 191d and the force-applying part 191e are pulled to the left. Since the force-applying part 191e and the force-receiving part 191d are driven to swing by the seventh protrusion 383, the torsion spring 190 also twists in the circumferential direction and produces elastic deformation. At the same time, since the fixed arm 191b is limited by the second limiting part 111g, the elastic deformation of the torsion spring 190 in the circumferential direction cannot be restored, so the force-applying part 191e and the force-receiving part 191d are blocked by the side walls of the first support part 111d and the second support part 111e and cannot be reset. The force-applying part 191e remains in contact with the second lever 207a1 as it moves to the left by the main body 191a. This keeps the first slider 207a in this position as well. Because the elastic force of the eighth elastic element 188 cannot overcome the elastic force of the torsion spring 190, the first slider 207a cannot return to its original position.

[0366] When the transmission assembly 208 in this embodiment needs to be reset, it is only necessary to pull the force-receiving part 191d and the force-applying part 191e to the right, place the force-applying part 191e on the first support part 111d and abut against the first support part 111d, and place the force-receiving part 191d on the second support part 111e and abut against the second support part 111e to complete the reset.

[0367] Example 24

[0368] like Figures 93 to 97 As shown, the difference between this embodiment and embodiment twenty-three is that in this embodiment, the actuating part 191c and the tenth elastic element 191 are separate structures. In this embodiment, the actuating part 191c is a rocker arm, which includes a pivot part 191c1, a first arm 191c2, and a second arm 191c3. The pivot part 191c1 is cylindrical. The first arm 191c2 is integrally formed and fixedly connected to the circumferential surface of the pivot part 191c1, and the second arm 191c3 is integrally formed and fixedly connected to the right end face of the pivot part 191c1. The pivot part 191c1 is rotatably sleeved on the positioning post 21b. The distance from the end of the first arm 191c2 away from the rotation axis of the pivot part 191c1 to the rotation axis of the pivot part 191c1 is greater than the distance from the end of the second arm 191c3 away from the rotation axis of the pivot part 191c1 to the rotation axis of the pivot part 191c1.

[0369] 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 face of the first cover 111, and the fourth limiting protrusion 191c1a is slidably installed in the limiting groove 191f. The limiting groove 191f 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 integrally connected to the first cover 111.

[0370] 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. The side of the locking protrusion 191c2a that is radially away from the pivot 191c1 is the locking surface.

[0371] The tenth elastic member 191 is located in the axial direction of the pivot portion 191c1 between the right surface of the pivot portion 191c1 and the first cover 111. The main body 191a of the tenth elastic member 191 is sleeved on the positioning shaft, and the fixing arm 191b is engaged in 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 side of the swing arm near the developing roller 131.

[0372] The specific working process of this embodiment will be described below, wherein the description of the rotation direction is based on... Figure 94 The perspective is the observation perspective. The difference between this embodiment and the previous embodiment lies in the fact 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 191c1. This causes the second arm 191c3 to be pushed by the seventh protrusion 383 and swing counterclockwise. The second arm 191c3 drives the pivot 191c1 to rotate counterclockwise, and the pivot 191c1 drives the first arm 191c2 to swing counterclockwise. The first arm 191c2 swings counterclockwise... During the process, the side 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 with the swing of the first arm 191c2, but the distance from the contact position between the first arm 191c2 and the second lever 207a1 to the rotation axis of the pivot 191c1 is always greater than the distance from the contact position between the second arm 191c3 and the seventh protrusion 383 to the rotation axis of the pivot 191c1. This allows the linear velocity of the seventh protrusion 383 to be 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 a second velocity and push the detection element within the image forming apparatus.

[0373] During the swinging of the first arm 191c2, the locking protrusion 191c2a interferes with the second lever 207a1, causing both the locking protrusion 191c2a and the second lever 207a1 to undergo elastic deformation. This results in a pressing force perpendicular to the contact surface being applied 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 pressing forces applied between the locking surface and the lower surface of the second lever 207a1 are opposite in direction and equal in magnitude. This cancels out the pressing forces, and at this point, the second lever 207a1 and the locking protrusion 191c2a remain stable, thus positioning the second lever 207a1 by the locking protrusion 191c2a.

[0374] The eighth elastic element 188 applies a rearward force to the first slider 207a, and the reset arm 191h of the tenth elastic element 191 applies a clockwise rotational force to the first arm 191c2. However, the elastic deformation of the second lever 207a1 and the locking protrusion 191c2a is greatest 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 191c1. When the lower surface of the second lever 207a1 is parallel to the locking surface, the contact surface between the lower surface of the second lever 207a1 and the locking surface is located in the third direction in front of the rotation axis of the pivot 191c1, so the elastic deformation of the second lever 207a1 and the locking protrusion 191c2a is smaller at this time. Therefore, the force applied by the eighth elastic element 188 to the first slider 207a and the force applied by the tenth elastic element 191 to the first arm 191c2 are insufficient to cause the locking protrusion 191c2a and the second lever 207a1 to produce a larger deformation, thus preventing the first slider 207a and the lever from resetting. This results in the first slider 207a being stably locked by the locking protrusion 191c2a.

[0375] When it is necessary to reset the first slider 207a and the rocker arm, the user only needs to manually pull the first slider 207a forward. The second lever 207a1 will no longer apply pressure to the locking surface, the force balance will be broken, and the rocker arm will automatically reset under the elastic force of the tenth elastic element 191. After the rocker arm is reset, the user releases his hand, and the eighth elastic element 188 will pull the first slider 207a back to its original position.

[0376] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
