In this embodiment, the first conductive member 41a can be made of conductive materials such as conductive metal sheets, metal wires or conductive resins.

[0088] The second conductive member 42a is used to transfer the potential from the second end 12 to the first end 11. In this embodiment, the second conductive member 42a is preferably a powder knife, and the other end of the powder knife abuts against the circumferential surface of the developer body, so that when the developing roller 131 rotates, the developer carried on the developer body passes through the powder knife and the developer thickness is controlled by the powder knife to prevent uneven developer thickness. The powder knife is made of conductive metal material or conductive resin material, and extends in the first direction and extends from the first end 11 to the second end 12.

[0089] The intermediate conductive member 43a is located at the first end 11. The intermediate conductive member 43a includes a third conductive portion 432, a third main body portion 431, a third positioning portion and a movable portion 433. In this embodiment, the intermediate conductive member 43a can be made of a bent metal sheet as a whole, or can be made of conductive materials such as conductive resin. The third main body portion 431 extends in the front-to-back direction. The third main body portion 431 is located between the third conductive portion 432 and the movable portion 433 in the front-to-back direction. The third positioning portion is connected to the left end of the third main body portion 431 and a third positioning hole is formed on the third positioning portion. The box body 10 is provided with a third positioning column 435 inserted into the third positioning hole, so that the intermediate conductive member 43a is positioned by the third positioning column 435 to prevent the intermediate conductive member 43a from falling off or shaking from the box body 10.

In order to prevent poor contact, the third conducting part 432 is bent in a "V" shape, so that when the third conducting part 432 is inserted into the gap between the right end of the powder discharge knife and the first end 11, the third conducting part 432 is squeezed to produce elastic deformation. Under the action of the elastic force, the third conducting part 432 and the powder discharge knife can be more closely contacted, and the third conducting part 432 is clamped between the right end of the powder discharge knife and the first end 11, which further positions the intermediate conductive member 43a, and further prevents the intermediate conductive member 43a from falling off or shaking from the box body 10. An angle is formed between the movable portion 433 and the third main body portion 431 by metal bending. The extension direction of the movable portion 433 intersects with the extension direction of the third main body portion 431, so that the rear end of the movable portion 433 is further to the right than the front end. The movable portion 433 can move between the contact position and the separation position. When the movable portion 433 is in the separation position, there is a first angle between the movable portion 433 and the third main body portion 431. When the movable portion 433 is in the contact position, there is a second angle between the movable portion 433 and the third main body portion 431. The first angle is greater than the second angle. When the movable portion 433 is in the contact position, it contacts and is electrically connected to the grounding conductive member 44a. When the movable portion 433 is in the separation position, it does not contact and is not electrically connected to the grounding conductive member 44a. The rear end of the movable portion 433 is also fixedly provided with a first driven portion 434, which is formed by extending downward from the rear end of the movable portion 433.

[0090] The grounding conductive member 44a includes a fourth main body 441, a first electrical contact portion 442 and a second electrical contact portion 443. In this embodiment, the grounding conductive member 44a is made of a metal sheet as a whole, and can also be made of a conductive material such as a conductive resin. The first electrical contact portion 442 is located at the front end of the fourth main body 441, and the second electrical contact portion 443 is located at the rear end of the fourth main body 441. The first electrical contact portion 442 has an upwardly tilted bending portion. When viewed from top to bottom, the projection of the movable portion 433 overlaps with that of the fourth main body 441, but the movable portion 433 is located above the fourth main body 441 and there is a gap between the movable portion 433 and the fourth main body 441 in the vertical direction. The bending portion of the first electrical contact portion 442 overlaps with the movable portion 433 in the vertical direction, so that the movable portion 433 can contact the bending portion of the first electrical contact portion 442 when it moves. A fourth positioning hole is provided on the fourth main body 441, and a fourth positioning post 444 is also provided on the box body 10. The fourth positioning post 444 protrudes upward and is inserted into the fourth positioning hole, so as to position the grounding conductive member 44a and prevent the grounding conductive member 44a from falling off and shaking from the box body 10. The first electrical contact portion 442 is used to make electrical contact with the movable portion 433, and the second electrical contact portion 443 is used to make electrical contact with the grounding member in the image forming device. In one embodiment, the first conductive member 41a, the second conductive member 42a, the intermediate conductive member 43a, and the grounding conductive member 44a can be integrally formed or partially integrally formed.

[0091] The developing box 1 of this embodiment also includes a control component, which is used to control the movable part 433 to move between the contact position and the separation position. The control component includes a first rotating member 51a, which is a toothless gear. The first rotating member 51a is meshed with the driving gear 212, so as to receive power from the driving part 21a and rotate. The rotation axis of the first rotating member 51a extends in the first direction. The first rotating member 51a is rotatably located at the first end 11 and supported by the first support shaft protruding to the right in the first direction. The first rotating member 51a is provided with a first control protrusion 511a and a second control protrusion 512a. The first control protrusion 511a and the second control protrusion 512a protrude to the left in the first direction from the left end surface of the first rotating member 51a. The number of control protrusions on the first rotating member 51a is not limited in this embodiment. A first contact surface is provided on the first control protrusion 511a, and a second contact surface is provided on the second control protrusion 512a. The first contact surface and the second contact surface are used to contact with and push the first driven part 434, so that the first driven part 434 drives the movable part 433 to move. The first contact surface and the second contact surface are arc surfaces (the arc surfaces include inclined surfaces), and the contact is smoother by setting the arc surfaces.

[0092] The developer box 1 of the present embodiment also includes an identification component, the identification component includes a first chip 32, the first chip 32 includes a storage medium and an electrical contact surface 33, the storage medium is electrically connected to the electrical contact surface 33, the storage medium and the electrical contact surface 33 can be a separate combination or an integral molding, the electrical contact surface 33 is used to contact and electrically connect with the electrical contact terminal in the image forming device, so that the image forming device can read the information stored in the storage medium (such as the model, life, capacity, etc. of the developer box) through the electrical contact surface 33, the electrical contact surface 33 is located at the first end 11, and the third direction is the electrical contact surface 33, in this embodiment, the storage medium and the electrical contact surface 33 are jointly arranged and fixed on the substrate, the substrate is supported by the chip holder 31 and fixed on the chip holder 31, the chip holder 31 is fixedly arranged at the first end 11, preferably the chip holder 31 and the first protective cover 111 are integrally formed, the electrical contact surface 33 is a copper sheet or a conductive metal sheet fixedly arranged on the substrate, in other embodiments, the storage medium and the substrate can also be separated from the electrical contact surface 33, such as the storage medium is arranged at the second end 12, and the storage medium and the electrical contact surface 33 are electrically connected through conductive components such as wires. In other embodiments, the identification component may not be provided.

[0093] The following is the specific operation process of the control components and conductive components:

[0094] When the developing cartridge 1 is installed in the image forming device, the power receiving portion 411 contacts and is electrically connected to the power supply terminal in the image forming device (power is supplied to the power supply terminal by the power supply circuit in the image forming device), and the second electrical contact portion 443 contacts the grounding member in the image forming device. In the initial state, the movable portion 433 is located in the separated position, that is, there is no electrical connection between the intermediate conductive member 43a and the grounding conductive member 44a.

[0095] When the image forming device is started, when the driving part 21a receives the power provided by the image forming device and rotates clockwise, the driving part 21a drives the developing roller 131 and the powder feeding roller to rotate, and drives the first rotating member 51a to rotate counterclockwise, so that the first rotating member 51a moves from a position meshed with the driving gear to a position disengaged from the driving gear. At the same time, the normal potential provided by the power supply terminal can be guided to the developing roller shaft 1311 through the first conductive member 41a, so that the developing roller shaft 1311 has the same potential as the power supply terminal, thereby generating a potential difference between the developing roller 131 and the developer in the box body 10, so that the developer can be adsorbed.

[0096] As the first rotating member 51a rotates, in the process of the first rotating member 51a moving from a position meshing with the driving gear to a position disengaging from the driving gear, the duration from the start of rotation of the first rotating member 51a to the contact of the first control protrusion 511a with the first driven part 434 is T1. During this process, the movable part 433 is in a separated position, so the potential is at a normal potential during this process.

[0097] In the process of the first rotating member 51a moving from a position engaged with the driving gear to a position disengaged from the driving gear, the first control protrusion 511a contacts the first driven portion 434, and the first driven portion 434 is pushed to drive the movable portion 433 to move from the separation position to the contact position, thereby making the intermediate conductive member 43a electrically connected to the ground conductive member 44a. Since the ground conductive member 44a is electrically connected to the grounding member in the image forming device, the potentials of the power supply terminal, the first conductive member 41a, the second conductive member 42a, the intermediate conductive member 43a, and the grounding conductive member 44a are all reduced to the ground potential and last for a period of T2, so that the detection device in the image forming device (electrically contacting the power supply terminal) detects that the potential has changed once.

[0098] Then, as the first rotating member 51a rotates, the first control protrusion 511a disengages from the first driven portion 434. At this time, under the elastic action of the movable portion 433 itself, the movable portion 433 moves from the contact position to the separation position, so that the potential returns to the potential provided by the power supply circuit and lasts for a period of T3.

[0099] Then, as the first rotating member 51a rotates, the second control protrusion 512a contacts the first driven portion 434 and causes the movable portion 433 to move from the separation position to the contact position again, so that the potential is reduced to the ground potential again and lasts for T4.

[0100] Then, as the first rotating member 51 a rotates, the second control protrusion 512 a is disengaged from the first driven portion 434 , and the movable portion 433 moves from the contact position to the separation position under the action of elasticity and remains at the separation position without moving any more.

[0101] That is, in this embodiment, the first rotating member 51a can be regarded as a detected member, which moves by receiving the power transmitted by the driving part 21a, the first control protrusion 511a and the second control protrusion 512a can be regarded as detected protrusions, and the detected protrusions follow the movement of the detected member to control the change of the potential, and the control component can be regarded as a detected component.

[0102] Finally, the first rotating member 51a moves to a position where it is disengaged from the driving gear and stops rotating, thereby completing the detection process.

[0103] The detection device in the image forming device can determine the information of the developing box 1 (such as new, model, and capacity) by the number of times the potential drops to the ground potential, the duration of each time it drops to the ground potential, and the duration of the normal potential between two times.

[0104] For example, in this embodiment, if the developing cartridge 1 is an old developing cartridge 1 that has been used, the first rotating member 51 a is initially in a state of being disengaged from the driving gear, so the movable portion 433 does not move and the potential does not change.

[0105] And if the second control protrusion 512a is not provided in this embodiment, the number of times the potential is reduced to the ground potential is only one, and the image forming device can determine that the developing box 1 is a new developing box 1 and can print 3000 sheets of paper. If the number of times the potential is reduced to the ground potential is two, it can be determined that the developing box 1 is a new developing box 1 and can print 6000 sheets of paper. Similarly, those skilled in the art can also increase the number of control protrusions.

[0106] And those skilled in the art can also adjust the duration of T1 by adjusting the circumferential distance between the first control protrusion 511a and the toothless portion on the first rotating member 51a along the rotation direction. If the distance between the toothless portion and the first control protrusion 511a is longer, T1 increases, otherwise it decreases.

[0107] Those skilled in the art can also adjust the duration of T2 by adjusting the size of the first control protrusion 511a in the circumferential direction. If the size increases, T2 increases, and vice versa.

[0108] T3 can be adjusted by adjusting the distance between the first control protrusion 511a and the second control protrusion 512a in the circumferential direction. When the distance increases, T3 increases, and vice versa.

[0109] T4 can be adjusted by adjusting the size of the second control protrusion 512a in the circumferential direction. If the size increases, T4 increases, and vice versa.

[0110] In this embodiment, the following numerical ranges are obtained for T1, T2, T3, and T4, within which the developing box 1 can be installed in the image forming device without error: 200ms≤T1≤2000ms, 80ms≤T2≤1200ms, 300ms≤T3≤600ms, 80ms≤T4≤500ms.

[0111] Embodiment 2:

[0112] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the first embodiment.

[0113] like Figure 8As shown, the difference between this embodiment and the first embodiment is that:

[0114] The second conductive member is the developing roller shaft 1311, which receives the potential transmitted by the first conductive member 41a and transmits the potential to the first end 11. The first bracket 42b is fixedly mounted on the first end 11. The first bracket 42b is used to rotatably support the right end of the developing roller 131 shaft. The first bracket 42b is made of conductive resin. The first bracket 42b serves as a transition conductive member to receive the potential transmitted by the developing roller 1311. In one embodiment, the second conductive member may also be the roller shaft of the powder feeding roller or a separate conductive member.

[0115] The intermediate conductive member 43a, the third conductive portion 432 of the intermediate conductive member 43a is in contact with and electrically connected to the first bracket 42b, the third main body portion 431 is fixed to the first end 11, the movable portion 433 is fixedly connected to the upper end of the third main body portion 431, the movable portion 433 is tilted forward relative to the third main body portion 431, the first driven portion 434 is arranged at the front end of the movable portion 433 and has an angle with the movable portion 433, and the first driven portion 434 is tilted downward relative to the movable portion 433.

[0116] The first electrical contact portion 442 of the grounding conductive member 44 a is located on the upper side of the movable portion 433 .

[0117] In this embodiment, the first angle when the movable portion 433 is in the separation position is smaller than the second angle when the movable portion 433 is in the contact position.

[0118] In this embodiment, when the first rotating member 51a rotates from a position engaged with the driving gear to a position disengaged from the driving gear, the first control protrusion 511a and the second control protrusion 512a can contact the first driven part 434 and push the movable part 433 to swing upward and move from the separation position to the contact position.

[0119] By adopting the structure of this embodiment, the structure of the first conductive member 41a can be simplified. The first conductive member 41a does not need to be provided with the first conductive portion 413, and thus does not need to supply power to the powder discharge knife.

[0120] Embodiment three:

[0121] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the first embodiment.

[0122] like Figure 9 to Figure 10 As shown, the difference between this embodiment and the first embodiment is that:

[0123] The developing box 1 also includes a swinging member 45a, which is located at the front side of the grounding conductive member 44a. A swinging shaft 454 extending in the up and down directions is provided on the box body 10. The swinging member 45a can be installed on the swinging shaft 454 and can swing around the swinging shaft 454. A second driven part 451 and a second driving part 452 are provided on the swinging member 45a. The second driven part 451 is located at the right end of the swinging member 45a and extends downward, and the second driving part 452 is located at the left end of the swinging member 45a and extends upward. The left end surface of the intermediate conductive member 43a abuts against the second driving part 452. An upwardly protruding reset protrusion 453 is also provided at the upper end of the swinging member 45a. The reset protrusion 453 is located on the right side of the swinging shaft 454. A reset elastic member 455 is installed between the reset protrusion 453 and the fourth positioning column 444. In this embodiment, the reset elastic member 455 is a tension spring, and the swinging shaft 454 is located between the second driven part 451 and the second driving part 452.

[0124] By adopting the structure in this embodiment, the structure of the intermediate conductive member 43 a can be simplified, and the first driven part does not need to be provided on the intermediate conductive member 43 a.

[0125] During the process of the first rotating member 51a rotating from a position engaged with the driving gear to a position disengaged from the driving gear, the second driven portion 451 of the swinging member 45a is touched by the first control protrusion 511a and the second control protrusion 512a in sequence, so that the swinging member 45a swings clockwise (viewed from top to bottom), and then the second driving portion 452 pushes the movable portion 433 to move from the separation position to the contact position.

[0126] When the first control protrusion 531a and the second control protrusion 532a are out of contact with the second driven part 451, the swing member 45a swings counterclockwise under the elastic force of the reset elastic member 455, and no longer pushes the movable part 433. The movable part 433 moves from the contact position to the separation position under its own elastic action.

[0127] Embodiment 4:

[0128] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the second embodiment.

[0129] like Figure 11 to Figure 13 As shown, the difference between this embodiment and the second embodiment is that:

[0130] This embodiment includes a transmission gear 58a, which includes a first transmission gear 581a and a second transmission gear 582a that are coaxially arranged. The radius of the second transmission gear 582a is smaller than that of the first transmission gear 581a, and the second transmission gear 582a is integrally formed on the left end surface of the first transmission gear 581a.

[0131] A support plate protruding to the right is fixedly provided on the first end 11 . The support plate extends in the front-rear direction and protrudes to the right from the first end 11 .

[0132] The control assembly further includes a translation member 53a, which is mounted on the support plate and can slide in the front-to-back direction on the support plate. The translation member 53a is provided with a first control protrusion 531a, a second control protrusion 532a and a plurality of teeth 533a. The plurality of teeth 533a are arranged in the moving direction of the translation member 53a (i.e., arranged in the front-to-back direction), and the plurality of teeth 533a are meshed with the second transmission gear 582a, i.e., the translation member 53a in this embodiment is a rack. The first control protrusion 531a and the second control protrusion 532a are located on the left side of the plurality of teeth 533a and are arranged with intervals in the moving direction of the translation member 53a (i.e., arranged in the front-to-back direction), and the first control protrusion 531a is located in front of the second control protrusion 532a. A first contact surface 5311 is provided on the first control protrusion 531a, and a second contact surface 5321 is provided on the second control protrusion 532a. The first contact surface 5311 and the second contact surface 5321 are inclined relative to the front-to-back direction. Specifically, the front ends of the first contact surface 5311 and the second contact surface 5321 are located lower than the rear ends in the up-down direction.

[0133] In this embodiment, a second guide portion 421 is provided on the left end surface of the first bracket 42b, and the second guide portion 421 protrudes to the left from the left end surface of the first bracket 42b. A second guide hole is formed on the second guide portion 421 in the up-down direction, and the second guide hole penetrates the second guide portion 421. A second protrusion 422 is also integrally formed on the left end surface of the first bracket 42b, and a second positioning portion 423 extending from top to bottom is integrally formed on the second protrusion 422, and there is a gap between the second positioning portion 423 and the first bracket 42b in the left-right direction. The second positioning portion 423 and the second protrusion 422 are both located on the upper side of the second guide portion 421.

[0134] In this embodiment, the intermediate conductive member 43a includes a third elastic member 433a and a third sliding member 431. The third sliding member 431 is installed in the second guide hole of the second guide portion 421 and can slide along the second guide hole in the up-down direction. The lower end and the upper end of the third sliding member 431 extend downward and upward from the second guide hole respectively. The upper end of the third sliding member 431 is fixedly connected with the lower end of the third elastic member 433a. In this embodiment, the third elastic member 433a is a compression spring. The third positioning portion is inserted into the third elastic member 433a. The upper end of the third elastic member 433a abuts against the third protrusion, thereby positioning the third elastic member 433a to prevent the third elastic member 433a from falling off. The lower end of the third sliding member 431 is a movable portion 432a, which is formed by extending rightward from the lower end of the third sliding member 431. When projected in the front-back direction, the movable portion 432a overlaps with the projections of the first control protrusion 531a and the second control protrusion 532a. The third sliding member 431 is electrically connected to the first bracket 42 b through the third elastic member 433 a , and is also electrically connected to the first bracket 42 b through contact with the second guide hole.

[0135] In this embodiment, the grounding conductive member 44a further includes a fourth extension portion, which is formed by extending downward from the front end of the fourth main body portion 441, and a first electrical contact portion 442 of the grounding conductive member 44a is arranged at the lower end of the fourth extension portion, and the first electrical contact portion 442 is formed by extending forward from the lower end of the fourth extension portion. The first electrical contact portion 442 is located on the upper side of the movable portion 432a, and when the movable portion 432a is in the separation position, there is a gap between the movable portion 432a and the first electrical contact portion 442 in the vertical direction, and when the movable portion 432a is in the contact position, there is no gap between the movable portion 432a and the first electrical contact surface 33 in the vertical direction.

[0136] When the first transmission gear 581a drives the second transmission gear 582a to rotate clockwise, the second transmission gear 582a transmits power to the translation member 53a through the plurality of teeth 533a, causing the translation member 53a to move leftward, thereby causing the first control protrusion 531a and the second control protrusion 532a to contact the movable part 432a in turn.

[0137] The duration from when the translation member 53 a starts to move to when the first control protrusion 531 a contacts the movable portion 432 a is T1.

[0138] As the translation member 53a moves, the first control protrusion 531a contacts the movable part 432a and the contact lasts for a period of T2. When the first control protrusion 531a contacts the movable part 432a, since the first contact surface 5311 is inclined relative to the front-to-back direction, the first contact surface 5311 exerts an upward component force on the movable part 432a, thereby causing the movable part 432a to drive the third sliding part to slide upward and compress the third elastic member 433a, thereby causing the movable part 432a to move from the separation position to the contact position, and the movable part 432a forms an electrical connection with the grounding conductive member 44a.

[0139] As the translation member 53a moves, the entire process from the first control protrusion 531a breaking away from contact with the movable part 432a to the second control protrusion 532a contacting with the movable part 432a lasts for a period of time T3. During this process, the movable part 432a moves from the contact position to the separation position together with the third sliding member 431 under the elastic force of the third elastic member 433a.

[0140] Then, the second control protrusion 532a contacts the movable portion 432a for a duration of T4, so that the movable portion 432a moves from the separation position to the contact position again.

[0141] As the translation member 53a continues to move forward, the second control protrusion 532a is out of contact with the movable portion 432a, and the movable portion 432a moves from the contact position to the separation position again.

[0142] Finally, as the translation member 53a moves, the plurality of teeth 533a are all disengaged from the second transmission gear 582a, so that the translation member 53a stops moving, the detection process of the image forming device stops, and the developer box 1 successfully passes the detection.

[0143] That is, in this embodiment, the translation member 53a is a detected member, and the translation member 53a includes a first control protrusion 531a which can be regarded as a first detected protrusion and a second control protrusion 532a which can be regarded as a second detected protrusion.

[0144] Embodiment five:

[0145] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fourth embodiment.

[0146] like Fig.14 As shown, the difference between this embodiment and the fourth embodiment is that:

[0147] A support groove 112 is provided on the first end 11 to replace the support plate. The support groove 112 is grooved from top to bottom and has a closed lower end and an unclosed right end.

[0148] In this embodiment, the translation member 53a extends in the up-down direction, and the left end of the translation member 53a is integrally provided with an insertion portion 534a extending to the left from the translation member 53a. The insertion portion 534a can be inserted into the support groove 112, so that the translation member 53a is supported and limited by the support groove 112. In this embodiment, the movement direction of the translation member 53a is in the up-down direction along the support groove 112.

[0149] A plurality of teeth 533a are provided on the rear end of the translation member 53a and are arranged in the up-down direction. A first control protrusion 531a and a second control protrusion 532a are provided at the front end of the translation member 53a. The first control protrusion 531a and the second control protrusion 532a are arranged with intervals along the up-down direction. A chamfer is provided at the connection between the left end and the upper end of the first control protrusion 531a and the second control protrusion 532a, so that the contact between the first control protrusion 531a and the second control protrusion 532a and the movable part 433 is smoother.

[0150] The intermediate conductive member 43a, in this embodiment, is fixed to the second conductive member 42a by pasting. The intermediate conductive member 43a includes a pasting portion 434a and a movable portion 433. The pasting portion 434a is fixed to the right end surface of the second conductive member 42a by pasting and is electrically connected to the second conductive member 42a. The movable portion 433 is connected to the upper end of the pasting portion 434a and has an angle with the pasting portion 434a. The extension direction of the movable portion 433 intersects the up-down direction, and the upper end of the movable portion 433 is further to the right than the lower end. The first angle when the movable portion 433 is in the contact position is greater than the second angle when the movable portion 433 is in the separation position. The projection of the movable portion 433 overlaps with the projection of the first control protrusion 531a and the second control protrusion 532a in the up-down direction.

[0151] The grounding conductive member 44 a , in this embodiment, has a front end of a first electrical contact portion 442 , and the projection of the first electrical contact portion 442 and the movable portion 433 overlap in the left-right direction.

[0152] When the first transmission gear 581a drives the second transmission gear 582a to rotate, the translation member 53a moves upward along the sliding groove, so that the first control protrusion 531a and the second control protrusion 532a successively contact the movable part 433, so that the movable part 433 moves from the separation position to the contact position with the grounding conductive member 44a.

[0153] Embodiment six:

[0154] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fourth embodiment.

[0155] like Figure 15 to Figure 16 As shown, the difference between this embodiment and the fourth embodiment is that:

[0156] The second transmission gear 582a is a bevel gear.

[0157] The transmission gear also includes a third transmission gear 583a and a fourth transmission gear 584a which are coaxially arranged. The third transmission gear 583a is a bevel gear, and the third transmission gear 583a is meshed with the second transmission gear 582a. The rotation axis of the third transmission gear 583a extends in the up and down directions. A support seat 113 protruding to the right is fixedly arranged on the first end 11, and a third support shaft extending upward is arranged on the support seat 113. The third transmission gear 583a is coaxially sleeved on the third support shaft and can rotate around the third support shaft.

[0158] The fourth transmission gear 584a is coaxially fixedly disposed on the upper end of the third transmission gear 583a and is a spur gear.

[0159] The first protective cover 111 is provided with a limiting hole 1111 for supporting and limiting the translation member 53a, and the limiting hole 1111 penetrates the first protective cover 111 in the left-right direction. The translation member 53a can be slidably installed in the limiting hole 1111 relative to the limiting hole 1111, so that it is limited by the limiting hole 1111 and can only move in the left-right direction.

[0160] In this embodiment, the translation member 53a extends in the left-right direction, and the plurality of teeth 533a mesh with the fourth transmission gear 584a. The front end of the translation member 53a is provided with a first control protrusion 531a and a second control protrusion 532a, and the connection between the front end and the left end of the first control protrusion 531a and the second control protrusion 532a is provided with a chamfer, so that the contact with the movable part 433 is smoother.

[0161] In this embodiment, the intermediate conductive member 43a may not be provided. In this embodiment, a second protrusion 422 protruding upward is provided at the upper end of the first bracket 42b. In this embodiment, the first electrical contact portion 442 of the grounding conductive member 44a is provided as a movable portion 433, that is, the first electrical contact portion 442 can be movable relative to the grounding conductive member 44a. The movable portion 433 extends upward from the front end of the first conductive member 41a and then extends to the right to form a bend. The movable portion 433 overlaps with the projections of the first control protrusion 531a and the second control protrusion 532a in the left-right direction, and overlaps with the projection of the second protrusion 422 in the front-to-back direction.

[0162] When the first transmission gear 581a rotates, the power passes through the second transmission gear 582a and the third transmission gear 583a, and finally causes the fourth transmission gear 584a to rotate clockwise (viewed from top to bottom), and the fourth transmission gear 584a drives the translation member 53a to move from right to left, so that the first control protrusion 531a and the second control protrusion 532a successively contact the movable part 433, and then the movable part 433 moves from the separation position to the contact position twice. In this embodiment, the intermediate conductive member 43a is eliminated, which can reduce parts and reduce costs.

[0163] Embodiment seven:

[0164] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fourth embodiment.

[0165] like Figure 17 to Figure 18 As shown, the difference between this embodiment and the fourth embodiment is that:

[0166] A second swing shaft 424 protruding rightward is provided at the rear end of the first bracket 42b.

[0167] The middle conductive member 43a is provided with a through hole for inserting the second swing shaft 424, so that the middle conductive member 43a is supported by the second swing shaft 424, and the middle conductive member 43a can swing around the second swing shaft 424, and the swing shaft of the middle conductive member 43a first extends in the front-back direction. The lower end of the middle conductive member 43a is the driven part 431a, and the upper end of the middle conductive member 43a is the movable part 433. The second swing shaft 424 is located between the driven part 431a and the movable part 433 in the up-down direction. A reset elastic member 434a1 is installed between the left end of the middle conductive member 43a and the first end 11, and the reset elastic member 434a1 is a compression spring. The reset elastic member 434a1 is located at the lower side of the second swing shaft 424.

[0168] The front end of the grounding conductive member 44a is provided with a fourth extension portion extending downward, and the first electrical contact portion 442 is formed by extending forward from the lower end of the fourth extension portion. The intermediate conductive member 43a can swing around the second swing axis 424 between a separation position where the movable portion 433 is separated from the first electrical contact portion 442 and a contact position where the movable portion 433 is in contact with the first electrical contact portion 442. The projections of the first electrical contact portion 442 and the movable portion 433 in the left-right direction overlap.

[0169] The first control protrusion 531a and the second control protrusion 532a are arranged at the left end of the translation member 53a and protrude to the left. The front end of the first control protrusion 531a and the second control protrusion 532a are connected with the left end with a chamfer, so that the first control protrusion 531a and the second control protrusion 532a contact the driven part 431a more smoothly. The projections of the first control protrusion 531a and the second control protrusion 532a and the driven part 431a in the front-back direction overlap.

[0170] When the translation member 53a moves from back to front, the first control protrusion 531a and the second control protrusion 532a successively touch the driven part 431a, so that the intermediate conductive member 43a moves from the separation position to the contact position twice. In the process of the intermediate conductive member 43a moving from the separation position to the contact position, under the power provided by the first control protrusion 531a and the second control protrusion 532a, the intermediate conductive member 43a swings counterclockwise (viewed from back to front), so that the movable part 433 contacts the first electrical contact part 442. When the first control protrusion 531a and the second control protrusion 532a are out of contact with the driven part 431a, the intermediate conductive member 43a swings clockwise (viewed from back to front) under the elastic force of the reset elastic member 434a1, so that the movable part 433 is out of contact with the first electrical contact part 442.

[0171] Embodiment eight:

[0172] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the second embodiment.

[0173] The difference between this embodiment and the second embodiment is that:

[0174] The transmission assembly includes a transmission gear, which is located between the first rotating member and the driving gear in the front-to-back direction. The transmission gear is meshed with the driving gear and the first rotating member at the same time. The position of the first rotating member and the transmission ratio can be adjusted by setting the transmission gear.

[0175] In this embodiment, a first magnetic member (first control protrusion) and a second magnetic member (second control protrusion) are provided on the first rotating member, and the N poles of the first magnetic member and the second magnetic member point to the axis of the first rotating member, and the S poles point in the direction away from the axis of the first rotating member.

[0176] A third magnetic member is fixedly mounted on the movable part, and the movable part is located at the lower side of the first electrical contact part of the grounded conductive member, and there is a gap between the movable part and the first electrical contact part in the up-down direction. The distance between the movable part and the rotation axis of the first rotating member in the up-down direction is greater than the radius of the circle formed by the path passed by the first magnetic member and the second magnetic member as the first rotating member rotates. The movable part and the third magnetic member are located above the rotation axis of the first rotating member. The S pole of the third magnetic member points to the rotation axis, and the N pole of the third magnetic member points to the direction away from the rotation axis of the first rotating member.

[0177] During the rotation of the first rotating member, when the first magnetic member and the second magnetic member successively pass through the highest point of their motion trajectory, they respectively generate repulsive forces on the third magnetic member, so that the third magnetic member drives the movable part to move upward, thereby making the movable part contact and electrically connected with the first electrical contact part. Thus, a double grounding effect is achieved, so that the detection device in the image forming device detects two potential changes, and the developing box 1 can pass the detection.

[0178] Embodiment nine:

[0179] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the first embodiment.

[0180] like Fig.19 The difference between this embodiment and the first embodiment is that:

[0181] The middle conductive member 43 a is not provided with a driven portion 442 a and a movable portion 443 a , and the rear end of the middle conductive member 43 a is a third electrical contact portion 437 .

[0182] The first end 11 is provided with a first pivot shaft 114 protruding upward in the up-down direction, and the grounding conductive member 44a is sleeved on the first pivot shaft 114 and can swing around the first pivot shaft 114. The grounding conductive member 44a includes a pivoting portion 441a, a driven portion 442a and a movable portion 443a that are integrally formed and fixedly connected together. The pivoting portion 441a is provided with a pivot hole for inserting the first pivot shaft 114, so that the grounding conductive member 44a can swing around the first pivot shaft 114, the driven portion 442a is connected to the lower end of the pivoting portion 441a and extends downward, and the movable portion 443a extends rightward from the pivoting portion 441a. The pivoting portion 441a contacts and is electrically connected to the third electrical contact portion 437. In this embodiment, the movable portion 443a is used to contact and be electrically connected to the grounding member in the image forming device. The driven portion 442a is located on the left side of the first rotating member 51a. A resetting elastic member 115 is installed between the movable portion 443a and the box body 10. The resetting elastic member 115 is a tension spring, one end of which is fixedly connected to the movable portion 443a and the other end of which is fixedly connected to the box body 10. Similarly, in this embodiment, the first rotating member 51a is regarded as a detected member.

[0183] The first control protrusion 511a and the second control protrusion 512a respectively have a first contact surface 5111 and a second contact surface 5121 which are arranged obliquely, and the first contact surface 5111 and the second contact surface 5121 intersect with the front-back direction and the left-right direction, and the first contact surface 5111 and the second contact surface 5121 are arranged to be farther from the first end 11 upstream than downstream in the rotation direction of the first rotating member 51a. The first contact surface 5111 and the second contact surface 5121 are used to contact the driven portion 442a.

[0184] When the first rotating member 51a receives power and rotates counterclockwise (viewed from right to left), the first contact surface 5111 of the first control protrusion 511a contacts the driven portion 442a, thereby generating a leftward force on the driven portion 442a, so that the driven portion 442a drives the entire grounding conductive member 44a to overcome the elastic force of the reset elastic member 115 and swing clockwise around the first pivot axis 114 (viewed from top to bottom), thereby causing the movable portion 443a to move from a separation position where it is not in contact with the grounding member to a contact position where it is in contact with the grounding member.

[0185] As the first rotating member 51a rotates, when the first contact surface 5111 is out of contact with the driven portion 442a, the grounding conductive member 44a swings counterclockwise under the elastic force of the reset elastic member 115, so that the movable portion 443a moves from the contact position to the separation position.

[0186] The working process of the second control protrusion 512a is the same as that of the first control protrusion 511a, which will not be repeated. Finally, the first rotating member 51a rotates to a position where it is disengaged from the driving gear, and the detection process is completed.

[0187] Embodiment ten:

[0188] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fourth embodiment.

[0189] like Fig. 20 As shown, the difference between this embodiment and the fourth embodiment is that:

[0190] In this embodiment, there is only one transmission gear. The left end of the first transmission gear 581a is coaxially fixedly connected with a threaded portion 5811a, and a thread groove is provided on the outer peripheral surface of the threaded portion 5811a.

[0191] The first end 11 is provided with a first guide rail 116 extending in the left-right direction, and a translation member 53a that can slide in the left-right direction along the first guide rail 116 is installed on the first guide rail 116. The upper end of the translation member 53a is fixedly provided with a first control protrusion 531a and a second control protrusion 532a. The first control protrusion 531a is located on the left side of the second control protrusion 532a. The first control protrusion 531a and the second control protrusion 532a are respectively provided with a first contact surface and a second contact surface that are inclined surfaces, and the first contact surface and the second contact surface intersect with the left-right direction and the up-down direction. The left ends of the first contact surface and the second contact surface are lower than the right ends. The left end of the translation member 53a is provided with an insertion protrusion 534a1 that protrudes to the left and is inserted into the thread groove. The translation member 53a is regarded as a detected member having a detected protrusion.

[0192] When the first transmission gear 581a receives power and rotates counterclockwise, it drives the threaded portion 5811a to rotate counterclockwise together. Through the cooperation between the thread groove and the insertion protrusion 534a1, the thread groove provides a leftward force on the insertion protrusion 534a1, so that the translation member 53a slides leftward and drives the first control protrusion 531a and the second control protrusion 532a to move leftward, so that the first contact surface and the second contact surface contact the driven portion 442a in sequence. When the first contact surface contacts the driven portion 442a, the driven portion 442a is pressed against the driven portion 442a. The leftward force is generated, so that the grounding conductive member 44a swings clockwise, thereby causing the movable portion 443a to move from the separation position to the contact position. Since there is a gap between the first control protrusion 531a and the second control protrusion 532a in the left-right direction, when the first contact surface is out of contact with the driven portion 442a, the second contact surface 5121 does not immediately contact with the driven portion, so the grounding conductive member 44a swings counterclockwise under the action of the reset elastic member 115, causing the movable portion 443a to move from the contact position to the separation position. The action process when the second control protrusion 532a contacts the driven portion 442a is the same as that of the first control protrusion 531a, and will not be repeated. Finally, the first transmission gear 581a rotates to a position where it is out of mesh with the driving gear and stops rotating, completing the detection process. That is, in this embodiment, there is no need to set teeth on the translation member 53a, and movement is only generated after being abutted.

[0193] Embodiment eleven:

[0194] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the second embodiment.

[0195] like Fig.21 As shown, the difference between this embodiment and the second embodiment is that:

[0196] The driven part 442a and the movable part 443a are not provided on the intermediate conductive part 43a. In this embodiment, the intermediate conductive part 43a is a conductive elastic part, specifically a tension spring. The front end of the intermediate conductive part 43a is fixedly connected and electrically connected to the first bracket 42b, and the rear end is fixedly connected and electrically connected to the first electrical contact part at the front end of the grounding conductive part 44b. The fixed connection can be by means of clamping or welding.

[0197] The first end 11 is provided with a first track, and the grounding conductive member 44b can move relative to the box body 10 in the front-to-back direction along the first track. The grounding conductive member 44b includes a first electrical contact portion, a fourth main body portion, and a movable portion 443b. The front end of the fourth main body portion is the first electrical contact portion. The movable portion 443b is fixedly arranged at the rear end of the fourth main body portion and extends backward. The movable portion 443b can move between a contact position in which it contacts and is electrically connected to the grounding member in the image forming device and a separation position in which it does not contact and is not electrically connected to the grounding member in the image forming device. The lower end of the fourth main body portion is also provided with a driven portion 442b, which is formed by extending downward from the fourth main body portion.

[0198] In this embodiment, the transmission assembly also includes a first idler gear, which includes a large-diameter gear portion and a small-diameter gear portion that are coaxially integrated. The large-diameter gear portion is meshed with the driving gear, and the small-diameter gear portion is meshed with the first rotating member 51a, so that the axial position and transmission ratio of the first rotating member 51a can be adjusted.

[0199] When the first rotating member 51a receives power and rotates clockwise (from right to left), the first control protrusion 511a and the second control protrusion 512a contact the driven part 442b in sequence, so that the grounding conductive member 44a moves backward along the first track and stretches the intermediate conductive member 43a, so that the movable portion 443b moves backward from the separation position to the contact position. After the first control protrusion 511a is out of contact with the driven part 442b, the grounding conductive member 44a moves forward under the elastic force of the intermediate conductive member 43a, so that the movable portion 443b moves forward from the contact position to the separation position. The action process of the second control protrusion 512a is the same as that of the first control protrusion 511a, and will not be repeated. When the first rotating member 51a moves to the point where the missing tooth portion is opposite to the small diameter gear portion, the first rotating member 51a stops rotating, and the movable portion 443b of the grounding conductive member 44a is kept in the separation position under the elastic force of the intermediate conductive member 43a. In some embodiments, the ground conductive member 44 a may further move or swing in the second direction or the third direction.

[0200] Embodiment 12:

[0201] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fifth embodiment.

[0202] like Fig. 22 As shown, the difference between this embodiment and the fifth embodiment is that:

[0203] The intermediate conductive member 43a is not provided with the driven portion 442c and the movable portion 443c, and the third electrical contact portion is provided at the rear end of the third main body portion instead of the movable portion 443c.

[0204] The first end 11 is provided with a first pivot shaft 1112 protruding upward, and the third electrical contact portion is provided with a through hole for the first pivot shaft 1112 to be inserted into.

[0205] The grounding conductive member 44c includes an integrally formed fourth main body 441c, a driven portion 442c, and a movable portion 443c. A pivot hole is formed on the fourth main body 441c, and the first pivot shaft 1112 is inserted into the pivot hole, so that the grounding conductive member 44c is positioned by the first pivot shaft 1112 and can swing around the first pivot shaft 1112. The grounding conductive member 44c is located above the third electrical contact portion, and because the first pivot shaft 1112 is simultaneously inserted into the through hole on the third electrical contact portion and the pivot hole on the fourth main body 441c, the third electrical contact portion and the fourth main body 441c can be overlapped in the up and down directions, thereby maintaining the contact and electrical connection between the fourth main body 441c and the third electrical contact portion. The movable portion 443c extends backward from the rear end of the fourth main body 441c, and the driven portion 442c is fixed to the front end of the fourth main body 441c and extends downward from the front end of the fourth main body 441c. The projection of the driven portion 442c in the vertical direction overlaps with the projection of the first control protrusion 531a and the second control protrusion 532a in the vertical direction. A reset elastic member is also installed between the fourth main body 441c and the box body. The reset elastic member is a tension spring. The connection position of the reset elastic member and the fourth main body 441c is located at the rear side of the fourth pivot axis.

[0206] When the first transmission gear 581a rotates, the translation member 53a moves upward so that the first control protrusion 531a and the second control protrusion 532a contact the driven part 442c in turn, so that the driven part 442c is subjected to a leftward force, causing the grounding conductive member 44c to swing clockwise (as viewed from top to bottom) around the first pivot axis 1112, thereby causing the movable part 443c to move from a separation position in which it is not electrically in contact with the grounding member to a contact position in which it is electrically in contact with the grounding member.

[0207] When the first control protrusion 531a is out of contact with the driven part 442c, the grounding conductive member 44c swings counterclockwise around the first pivot axis 1112 under the elastic force of the reset elastic member, so that the movable part 443c moves from the contact position to the separation position. The action process of the second control protrusion 532a is the same as that of the first control protrusion 531a and will not be repeated. After the first control protrusion 531a and the second control protrusion 532a are in contact with the driven part 442c and are out of contact, the grounding conductive member 44c no longer moves so that the movable member remains in the separation position.

[0208] Embodiment 13:

[0209] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the sixth embodiment.

[0210] like Fig.23 As shown, the difference between this embodiment and the sixth embodiment is that:

[0211] Multiple teeth 533a are fixedly arranged at the front end of the translation member 53a, the first control protrusion 531a and the second control protrusion 532a are fixedly arranged at the rear end of the translation member 53a, the translation member 53a is located on the rear side of the fourth transmission gear 584a and the multiple teeth 533a are meshed with the fourth transmission gear 584a.

[0212] The intermediate conductor 43a, the structures of the intermediate conductor 43a and the grounding conductor 44b in this embodiment are roughly the same as those in the twelve embodiments, with the difference that the driven portion 444b of the grounding conductor 44b is arranged at the upper end of the fourth main body portion 441b, and when the movable portion 443b is in the separated position, the projection of the driven portion 444b in the left and right directions overlaps with the projection of the first control protrusion 531a and the second control protrusion 532a, and the first control protrusion 531a is located on the right side of the second control protrusion 532a.

[0213] When the first transmission gear 581a rotates counterclockwise (from right to left), the fourth transmission gear 584a rotates clockwise (from top to bottom), thereby driving the translation member 53a to move from left to right relative to the box body 10, so that the first control protrusion 531a and the second control protrusion 532a have been in contact with and out of contact with the driven part 444bb. Thus, the grounding conductive member 44b can move in the front-to-back direction, and the movable part 443b can move between the contact position and the separation position.

[0214] Embodiment 14:

[0215] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the sixth embodiment.

[0216] like Figure 24-25 As shown, the difference between this embodiment and the sixth embodiment is that:

[0217] In this embodiment, there is no translation member, the first rotating member 55a is a spur gear and meshes with the fourth transmission gear 584a, the first end 11 is fixedly provided with a second rotating shaft 118 extending in the vertical direction, the first rotating member 55a is rotatably sleeved on the second rotating shaft 118, the rotation axis of the first rotating member 55a extends in the vertical direction, the upper end surface of the first rotating member 55a is provided with a first control protrusion 551 and a second control protrusion 552 protruding upward, the first control protrusion 551 and the second control protrusion 552 are arranged along the circumferential direction of the first rotating member 55a, and a toothless portion is provided on the circumferential surface of the first rotating member 55a. That is, in this embodiment, the first rotating member 55a is used as a detected member with a detected protrusion.

[0218] A cover 151a is also installed at the upper end of the box body 10. The cover 151a is used to cover the third transmission gear 583a, the fourth transmission gear 584a and the first rotating member 55a in the vertical direction. An observation port 1511 is provided on the cover 151a. The first rotating member 55a is exposed through the observation port 1511 in the vertical direction, so that the first rotating member 55a can be observed from the outside. A fifth positioning column 1512 is fixedly provided on the rear wall of the observation port 1511, and the fifth positioning column 1512 protrudes forward.

[0219] The intermediate conductive member 43a is in the shape of a torsion spring formed by bending a steel wire as a whole. A receiving groove for receiving the third conductive part 432 is provided on the upper end surface of the cover 151a. The receiving groove can also limit the third conductive part 432 to prevent the third conductive part 432 from being misplaced. The front end of the third conductive part 432 is in contact with and electrically connected to the powder outlet knife. The third main body 431 is in the shape of a hollow cylinder formed by winding a steel wire. The third main body 431 is mounted on the fifth positioning column 1512 so that the intermediate conductive member 43a is supported by the fifth positioning column 1512. A movable opening 1513 is also provided on the cover 151a, and the movable opening 1513 penetrates the cover 151a in the up-down direction. A first abutted portion is provided at the right end of the movable opening 1513. The movable portion 433 is located in the movable opening 1513. The movable portion 433 includes a driven portion 434b protruding downwardly formed by bending a steel wire. The driven portion 434b overlaps with the movement trajectories of the first control protrusion 551 and the second control protrusion 552 in the up-down direction. The right end of the movable portion 433 abuts against the upper surface of the first abutted portion. When the intermediate conductive member 43a is installed on the fifth positioning column 1512, the third conducting portion 432 abuts against the upper surface of the accommodating groove, and the movable portion 433 abuts against the upper surface of the first abutted portion, so that the intermediate conductive member 43a generates elastic deformation and has an elastic pre-tightening force to prevent the intermediate conductive member 43a from loosening, and the movable portion 433 always remains downwardly abutted against the first abutted portion under the action of the elastic force.

[0220] The grounding conductive member 44a is in the shape of a torsion spring formed by bending a steel wire. The first end 11 is fixedly provided with a sixth positioning column 116a, which protrudes to the right. The first electrical contact portion 442 of the grounding conductive member 44a extends forward and abuts against the upper surface of the cover 151a. The first electrical contact portion 442 is located below the movable portion 433. The movable portion 433 abuts downward on the first electrical contact portion 442 under the action of elastic force. When the movable portion 433 is in the contact position, the first electrical contact portion 442 contacts and is electrically connected to the movable portion 433. When the movable portion 433 is in the separation position, the first electrical contact portion 442 does not contact and is not electrically connected to the movable portion 433. The fourth main body 441 of the grounding conductive member 44a is in the shape of a hollow cylinder formed by winding a steel wire. The fourth main body 441 is sleeved on the sixth positioning column 116a so that the grounding conductive member 44a is supported by the sixth positioning column 116a. The second electrical contact portion 443 is formed by extending backward from the fourth main body portion 441, and a second abutted portion 1113 is fixedly provided at the rear end of the first protective cover 111, and the second electrical contact portion 443 abuts against the upper surface of the second abutted portion 1113, and a limiting portion 1114 is also fixedly provided on the second abutted portion 1113, and the limiting portion 1114 and the second abutted portion 1113 jointly form a limiting groove with openings at the left end, the front end and the rear end, so that the second electrical contact portion 443 is limited in the up and down directions and the right direction when inserted into the limiting groove, so as to prevent the second electrical contact portion 443 from being misplaced.

[0221] When the driving part 21a receives power provided by the image forming device and rotates, the power is finally transmitted to the first rotating member 55a through the driving part 21a, the first transmission gear 581a, the second transmission gear 582a, the third transmission gear 583a, and the fourth transmission gear 584a, so that the first rotating member 55a rotates from a position engaged with the fourth transmission gear 584a to a position disengaged from the fourth transmission gear 584a.

[0222] During the rotation of the first rotating member 55a, the first control protrusion 551 and the second control protrusion 552 contact the driven part 434b in sequence, so that the driven part 434b is pushed upward by the first control protrusion 551 and the second control protrusion 552 in sequence, so that the movable part 433 swings upward twice and moves from the contact position to the separation position. When the driven part 434b is out of contact with the first control protrusion 551 and the second control protrusion 552, the movable part 433 swings downward under the action of the elastic force and moves from the separation position to the contact position.

[0223] The number of the limiting portions 1114 may also be multiple, and the two limiting portions 1114 are opened to the left and the right respectively, so that the second electrical contact portion 443 is limited by the limiting portions 1114 in both the left and right directions.

[0224] The limiting portion 1114 may also be configured to be clamped on the second abutting portion 1113 in a clamping manner and clamp the second electrical contact portion 443 between the limiting portion 1114 and the second abutting portion 1113 .

[0225] Limiting protrusions 1115 protruding upward and downward can be respectively provided on the upper surface and the lower surface of the limiting groove formed by the limiting portion 1114 and the second abutting portion 1113, and the second electrical contact portion 443 is arranged between the limiting protrusion 1115 and the right end surface of the limiting groove, so that the limiting protrusion 1115 and the right end surface of the limiting groove jointly limit the second electrical contact portion 443 in the left and right directions.

[0226] The limiting portion 1114 can also be fixedly arranged on the first end 11, and the limiting portion 1114 is in the shape of a groove recessed to the left. The second electrical contact portion 443 is arranged in the limiting portion 1114, and the second abutting portion 1113 is used to abut against the left end of the limiting portion 1114 to close the opening at the right end of the limiting portion 1114, thereby preventing the second electrical contact portion 443 from detaching from the limiting portion 1114, thereby achieving the limitation of the second electrical contact portion 443.

[0227] Embodiment 15:

[0228] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the fourteenth embodiment.

[0229] like Figure 26 to Figure 29 As shown, the difference between this embodiment and the fourteenth embodiment is that the identification component includes a first chip 32, and the first chip 32 includes a storage medium and an electrical contact surface. In this embodiment, the number of electrical contact surfaces is four, and in other embodiments, the number of electrical contact surfaces may be other numbers but at least one electrical contact surface. The electrical contact surfaces are arranged in the first direction, and from right to left in the first direction are the first electrical contact surface 331, the grounding electrical contact surface 332, the third electrical contact surface 333, and the fourth electrical contact surface 334. When the developing box 1 is installed in the image forming device, the electrical contact surface contacts and is electrically connected with the identification terminal in the image forming device. The identification terminal in the image forming device also has four electrical contacts, and the four electrical contacts are arranged in the first direction, and from right to left in the first direction are the first electrical contact, the second electrical contact, the third electrical contact, and the fourth electrical contact. The first electrical contact, the second electrical contact, the third electrical contact and the fourth electrical contact correspond to the first electrical contact surface 331, the grounding electrical contact surface 332, the third electrical contact surface 333 and the fourth electrical contact surface 334 respectively, and the second electrical contact is electrically connected to the grounding member.

[0230] The middle conductive member 43a is fixedly mounted on the first end 11 and a front end of the middle conductive member 43a is in contact with and electrically connected to the powder discharge knife.

[0231] In this embodiment, the movable end portion 442 is located at the front end of the grounding conductive member 44a, and the driven portion 444b is located between the movable end portion 442 and the fourth main body 441 in the front-to-back direction. The driven portion 444b is in the shape of a protrusion protruding upward. In this embodiment, the movable end portion 442 and the driven portion 444b are both located below the first rotating member 55a, and the first control protrusion 551 and the second control protrusion 552 are arranged on the lower surface of the first rotating member 51a. The first control protrusion and the second control protrusion can contact the driven portion 444b to apply a force to the driven portion 444b. Under the action of the force applied by the first control protrusion 551 and the second control protrusion 552 and the elastic force of the grounding conductive member 44a itself, the driven portion 444b drives the movable end portion 442 to move between a contact position where it contacts and is electrically connected to the rear end of the intermediate conductive member 43a and a separation position where it does not contact and is not electrically connected to the rear end of the intermediate conductive member 43a. In this embodiment, the second electrical contact portion 443 at the rear end of the grounding conductive member 44a does not directly contact the grounding member.

[0232] The substrate is fixedly provided with a chip holder 34, which is fixed to the substrate by welding or bonding and electrically connected to the grounding electrical contact surface 332. The chip holder 34 is also in contact with and electrically connected to the chip holder 31. In this embodiment, the chip holder 31 and the first protective cover 111 are both made of conductive materials such as conductive resin or metal. The chip holder 31 is fixedly mounted on the right end of the first protective cover 111 and is electrically connected to the first protective cover 111. The chip holder 34 can be regarded as a grounding transfer conductive member.

[0233] The left end of the first protective cover 111 is provided with an extension portion 1116, which extends leftward from the left end of the first protective cover 111, and the extension portion 1116 abuts against and is electrically connected to the second electrical contact portion 443. The first control protrusion 551 and the second control protrusion 552 move together with the fourth transmission gear 584a. When the first control protrusion 551 contacts the driven portion 444b, the driven portion 444b is pressed downward, so that the driven portion 444b drives the movable end portion 442 to produce elastic deformation and move downward from the separation position to the contact position. With the movement of the first control protrusion 551, when the first control protrusion 551 is out of contact with the driven portion 444b, the movable end portion 442 moves upward from the contact position to the separation position under the elastic action of the grounding conductive member 44a itself. The working process of the second control protrusion 552 is the same as that of the first control protrusion 552, which will not be repeated.

[0234] Compared with other embodiments, the present embodiment is electrically connected to the grounding member through the grounding electrical contact surface 332, and there is no need to provide a conductive member on the developing box 1 that extends outward from the developing box 1 and contacts the grounding member. This greatly reduces the risk of the conductive member used for grounding being deformed by collision during transportation.

[0235] Embodiment 16:

[0236] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the first embodiment.

[0237] like Fig.30 and Fig.31 As shown, the difference between this embodiment and the first embodiment is that:

[0238] The identification component includes a first chip 32 , and the first chip 32 includes a storage medium and a control module.

[0239] In this embodiment, the second conductive member 42c is a wire, which extends from the second end 12 to the first end 11 along the first direction, the left end of the wire is fixedly connected and electrically connected to the electric receiving part, the right end of the wire is fixedly connected to the chip 32 and electrically connected to the control module, and the control module is also electrically connected to the grounded electrical contact surface 332. The control module is used to control whether the second conductive member 42c is electrically connected to the grounded electrical contact surface 332. That is, in this embodiment, the control module can be regarded as a detected component.

[0240] In this embodiment, there is no need to set gears other than the driving part 21a, the developing gear 22 and the powder feeding gear 23, nor is there a need to set an intermediate conductive part 43a and a grounding conductive part 44a, thereby reducing the number of parts, lowering costs and simplifying the structure.

[0241] When the developer cartridge 1 in this embodiment is installed in the image forming device, the first electrical contact, the third electrical contact, and the fourth electrical contact supply power to the chip. In other embodiments, one or more of the first electrical contact, the third electrical contact, and the fourth electrical contact may supply power to the chip. When the chip receives the power provided by the image forming device, the image forming device can read the information stored in the storage medium to determine the model, capacity, life, and other information of the developer cartridge 1 and prompt the user. At the same time, the control module starts to work, so that the second conductive member 42c and the grounded electrical contact surface 332 are connected and disconnected according to a regular pattern. Specifically, when the developer cartridge 1 is installed in the image forming device and the chip receives the power provided by the image forming device, the second conductive member 42c and the grounded electrical contact surface 332 are first in a disconnected state (i.e., not electrically connected) and last for a period of T1, and then the control module causes the second conductive member 42c and the grounded electrical contact surface 332 to enter a conductive state (i.e., electrically connected) and last for a period of T2, so that the second conductive member 42c is grounded through the grounded electrical contact surface 332. Then the control module causes the second conductive member 42c and the grounded electrical contact surface 332 to enter a disconnected state and last for a period of T3, and then the control module causes the second conductive member 42c and the grounded electrical contact surface 332 to enter a connected state again and last for a period of T4, and finally the control module causes the second conductive member 42c and the grounded electrical contact surface 332 to remain in a disconnected state.

[0242] The control module may be configured to repeat the above process when power is restored after power failure, so that the user can reuse the developing cartridge 1 after taking it out of the image forming device without replacing a new chip.

[0243] Embodiment 17:

[0244] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the sixteenth embodiment.

[0245] like Figure 32 to Figure 33 As shown, the difference between this embodiment and the sixteenth embodiment is that:

[0246] The identification component includes a first chip 32 and a second chip 37. The first chip 32 includes a storage medium, and the second chip 37 includes a control module. A first electrical contact surface 331, a ground electrical contact surface 332, a third electrical contact surface 333, and a fourth electrical contact surface 334 are arranged on the upper surface of the first chip 32. A fifth electrical contact surface 335 is also arranged on the lower surface of the first chip 32. The fifth electrical contact surface 335 is electrically connected to the ground electrical contact surface 332.

[0247] A sixth electrical contact surface 371 is provided on the upper surface of the second chip 37. The second chip 37 is mounted on the chip bracket 31 and is located below the first chip 32. The sixth electrical contact surface 371 contacts and is electrically connected to the fifth electrical contact surface 335. A battery 372 and a switch 373 for supplying power to the control module are provided on the second chip 37. The switch 373 is used to control the conduction and disconnection between the battery 372 and the control module. The switch 373 can move between a conduction position that forms a circuit between the battery 372 and the control module and a disconnection position that disconnects the circuit between the battery 372 and the control module. In this embodiment, the switch 373 is a metal sheet. The second conductive member 42a is electrically connected to the control module of the second chip 37.

[0248] The chip holder 31 is provided with a slide rail 311, in which a moving member 35 that can slide in the first direction is installed, and a reset elastic member 36 is sleeved on the moving member 35, and the left end of the reset elastic member 36 abuts against the right end of the slide rail 311, and the right end of the reset elastic member 36 abuts against the limit protrusion on the moving member 35. The right end of the moving member 35 is provided with an inclined surface, and the right end of the first rotating member 51a is provided with a switch protrusion 511b protruding rightward along the first direction. The switch protrusion 511b is used to contact the inclined surface on the moving member 35 so as to apply a rightward force to the moving member 35. In this embodiment, the first rotating member 51a is a toothless gear. That is, in this embodiment, the control module can be regarded as the second detected member, the first rotating member 51a can be regarded as the first detected member, and the switch protrusion 511b can be regarded as the control protrusion.

[0249] The working process is as follows: when the developing box 1 is installed in the image forming device, the first rotating member 51a receives power and starts to rotate, so that the switch protrusion 511b contacts the moving member 35, so that the moving member 35 moves to the right and compresses the reset elastic member 36, and the right end of the moving member 35 pushes the switch member 373 so that the switch member 373 moves from the disconnected position to the connected position, so that the battery 372 starts to supply power to the control module of the second chip 37, so that the control module starts to work. The working process of the control module is the same as that of the sixteenth embodiment and will not be repeated. Compared with the existing detection structure, this embodiment also has the effect of simple structure and small number of parts.

[0250] In other embodiments, the second chip 37 may also be fixedly mounted on the second end 12 to achieve the same effect.

[0251] Embodiment 18:

[0252] Unless otherwise specified, the structure of the developing box 1 of this embodiment is the same as that of the first embodiment.

[0253] like Figures 34 to 40 As shown, the difference between this embodiment and the first embodiment is that:

[0254] In this embodiment, the electric receiving portion 411 is fixedly mounted on the second end 12 and is made of a conductive resin material (it may also be other conductive materials such as metal), and the electric receiving portion 411 is used to contact the detection rod in the image forming device and to contact and electrically connect with the power supply terminal in the image forming device. In this embodiment, the first conductive member 41a may not be provided with a developing contact portion that contacts the developing roller shaft 1311, that is, it is not electrically connected to the developing roller shaft 1311, and the powder feeding contact portion 414 is electrically connected to the powder feeding roller shaft.

[0255] The second conductive member 42a (powder discharge knife) contacts the developing body to transfer electric potential. The developing body and the developing roller shaft 1311 in this embodiment may not be electrically connected.

[0256] The middle conductive member 43a is a conductive torsion spring, which includes an integrally formed third conductive portion 432, a third main body portion 431, and a movable portion 433. The third main body portion 431 is a hollow cylinder formed by winding a conductive steel wire, the third conductive portion 432 is used to contact and electrically connect with the second conductive member 42a, a rightwardly protruding abutting protrusion is fixedly provided on the first end 11, and the third conductive portion 432 abuts upwardly against the abutting protrusion, so that the third conductive portion 432 is limited by the abutting protrusion to prevent the third conductive portion 432 from swinging upward, thereby ensuring the third conductive portion 432 and the second conductive member 42a Stable contact, the movable portion 433 is used to contact and electrically connect with the chip holder 31.

[0257] The grounding conductive part is a chip holder 31. In this embodiment, the chip holder 31 is made of a conductive resin material (it can also be other conductive materials such as metal, or an additional wire is provided for conduction). The chip holder 31 includes an integrally formed chip support portion 311a and a conductive extension portion 312. The chip support portion 311a is further to the right than the conductive extension portion 312, that is, the conductive extension portion 312 is formed by extending from the chip support portion 311a to the left. When viewed from the top and bottom directions, the conductive extension portion 312 at least covers a portion of the intermediate conductive part 43a (in this embodiment, the conductive extension portion 312 covers the movable portion 433 of the intermediate conductive part 43a). The chip support portion 311a includes a chip support groove 3111 which is recessed from top to bottom, and a first flange 3112 and a second flange 3113 are respectively provided on the front side wall and the rear side wall of the chip support groove 3111. The first flange 3112 protrudes backward from the front side wall of the chip support groove 3111, and the second flange 3113 protrudes forward from the rear side wall of the chip support groove 3111.

[0258] The first chip 32 includes a storage medium, an electrical contact surface, a substrate 32b and an electrical contact, and the electrical contact surface includes a first electrical contact surface 331, a grounding electrical contact surface 332, a third electrical contact surface 333, and a fourth electrical contact surface 334. The storage medium, the electrical contact surface, and the chip holder 34 are all fixedly arranged on the substrate 32b, and the storage medium is electrically connected to the electrical contact surface. The first electrical contact surface 331, the grounding electrical contact surface 332, the third electrical contact surface 333, and the fourth electrical contact surface 334 are arranged on the upper surface of the substrate 32b with intervals from right to left. The electrical contact surface is in contact with and electrically connected to the identification terminal in the image forming device, and the grounding electrical contact surface 332 is used to contact and electrically connect to the grounding terminal in the identification terminal, so that the grounding electrical contact surface 332 can be grounded.

[0259] The chip holder 34 is electrically connected to the grounding electrical contact surface 332 and is fixedly disposed on the lower surface of the substrate 32b. The chip holder 34 is formed by bending a steel sheet as a whole (in other embodiments, it may also be formed by integral injection molding of a conductive resin). When the substrate 32b is mounted on the chip support groove 3111, the lower surface of the substrate 32b is supported by the upper surfaces of the first flange 3112 and the second flange 3113. The chip holder 34 is located between the first flange 3112 and the second flange 3113 in the front-to-back direction. The first clamping portion 341 and the second clamping portion 342 are fixedly provided on the front wall and the rear wall of the chip holder 34, respectively. The first clamping portion 341 is formed by extending obliquely forward and upward from the front wall of the chip holder 34, and the second clamping portion 342 is formed by extending obliquely backward and upward from the rear wall of the chip holder 34. The lower ends of the first clamping portion 341 and the second clamping portion 342 are connected to the chip holder 34, and the upper ends of the first clamping portion 341 and the second clamping portion 342 are used to abut against the lower surface of the first flange 3112 and the lower surface of the second flange 3113, respectively, so as to limit the movement of the substrate 32b so that the substrate 32b is positioned, and then the chip as a whole is fixed on the chip supporting groove 3111 to prevent loosening. In other embodiments, the storage medium, the substrate 32b and the chip holder 34 may also be arranged at other positions of the developer box 1. It is only necessary to set an additional wire between the storage medium and the electrical contact surface for electrical connection. Similarly, the chip holder 34 also only needs to set an additional wire to connect with the ground electrical contact surface 332.

[0260] The control assembly includes a movable member 57a and a first rotating member 51a (ie, a detected member).

[0261] The movable member 57 a includes an integrally formed movable pivot portion 571 , an extension arm 572 , a positioning matching portion 574 , and a movable guiding portion 573 .

[0262] A cylindrical movable support portion is fixedly provided on the first end 11, and the movable support portion is formed by extending rightward from the first end 11 in the first direction. The movable pivot portion 571 of the movable member 57a is cylindrical and a movable hole 5711 extending along the first direction is provided on the movable pivot portion 571. The movable hole 5711 is rotatably matched with the movable support portion, so that the movable member 57a can rotate around the movable support portion, and the rotation axis of the movable member 57a extends along the first direction.

[0263] The extension arm 572 extends backward from the circumferential surface of the movable pivot portion 571 along the radial direction of the movable pivot portion 571, and the positioning matching portion 574 is located at the rear end of the extension arm 572, that is, the free end of the extension arm 572. The movable guide portion 573 extends from the right end of the extension arm 572 to the right, and the upper surface of the movable guide portion 573 is a guide surface 5731. The guide surface 5731 is in the shape of an upwardly arched arc (in other embodiments, the guide surface 5731 can also be set as an inclined plane, such as a setting inclined from the front lower to the rear upper). A retaining surface 5732 is also provided on the guide surface 5731, and the retaining surface 5732 is formed by being recessed downward from the middle of the guide surface 5731.

[0264] The third main body portion 431 of the intermediate conductive member 43a is sleeved on the movable pivot portion 571, that is, the movable pivot portion 571 is inserted into the third main body portion 431, thereby supporting the intermediate conductive member 43a, and the third conductive portion 432 extends forward from the third main body portion 431 to the second conductive member 42a to contact and electrically connect with the second conductive member 42a, and the movable portion 433 extends backward to the rear end of the movable member 57a, and a ring-shaped movable positioning portion formed by bending is provided on the movable portion 433, and the positioning matching portion 574 is fixedly arranged at the free end of the extension arm 572 and protrudes from left to right, and the movable positioning portion is sleeved on the positioning matching portion 574, so that the movable portion 433 can move with the movement of the movable member 57a. The movable member 57a can move around the movable support portion with the movable portion 433 between the contact position and the separation position. When the movable member 57a is in the contact position, the movable portion 433 contacts and is electrically connected to the lower surface of the conductive extension portion 312. When the movable member 57a is in the separation position, the movable portion 433 does not contact and is electrically disconnected from the conductive extension portion 312. At the same time, the intermediate conductive member 43a can provide a reset force for the movable member 57a. When the movable member 57a moves from the contact position to the separation position, the intermediate conductive member 43a generates elastic deformation, so that the intermediate conductive member 43a can cause the movable member 57a to move from the separation position to the contact position.

[0265] The first rotating member 51a includes a connecting portion 536 and a plate-shaped portion 537 in addition to the toothless gear 535a. The connecting portion 536 is formed by extending leftward from the left end of the toothless gear 535a. The plate-shaped portion 537 is formed by extending leftward from the left end of the connecting portion 536. The plate-shaped portion 537 is provided with a first control protrusion 511a and a second control protrusion 512a. The first control protrusion 511a and the second control protrusion 512a are formed by protruding leftward from the left end surface of the plate-shaped portion 537. The first control protrusion 511a and the second control protrusion 512a are symmetrically arranged about the rotation axis of the first rotating member 51a. The first control protrusion 511a and the second control protrusion 512a follow the movement of the first rotating member 51a. When the first rotating member 51a moves from the meshing state to the disengaged state, the first control protrusion 511a and the second control protrusion 512a successively contact the guide surface 5731 to apply downward pressure to the movable member 57a, so that the movable member 57a drives the movable part 433 to move from the contact position to the disengaged position twice. And when the toothless gear 535a finally rotates to the disengaged state, the second control protrusion 512a moves to the retaining surface 5732, so that the outer circumferential surface of the second control protrusion 512a matches the concave shape of the retaining surface 5732, so that the second control protrusion 512a is retained in the retaining surface 5732, thereby maintaining the movable member 57a in the disengaged position, and preventing the first rotating member 51a from continuing to rotate under the elastic force of the intermediate conductive member 43a.

[0266] The diameter of the connecting portion 536 is smaller than the diameter of the toothless gear 535a, and the diameter of the connecting portion 536 is smaller than the distance between the first control protrusion 511a and the second control protrusion 512a. A reset protrusion 515a is fixedly provided on the right end surface of the toothless gear 535a, and the reset protrusion 515a includes a first inclined surface 5151 and a second inclined surface 5152. The first inclined surface 5151 is located at the front side of the second inclined surface 5152, and the first inclined surface 5151 intersects with the right end of the second inclined surface 5152 to form the tip of the reset protrusion 515a.

[0267] The first protective cover 111 is provided with an observation port, through which at least a part of the first rotating member 51a can be observed. The first protective cover 111 is also provided with an elastic arm, which extends from front to back. Preferably, the front end of the elastic arm is integrally formed with the first protective cover 111, and the rear end of the elastic arm is a free end. The rear end of the elastic arm is provided with a reset matching protrusion 1117, which protrudes from right to left. The reset matching protrusion 1117 includes a third inclined surface 11171 and a fourth inclined surface 11172. The third inclined surface 11171 is located at the front side of the fourth inclined surface 11172. The left ends of the third inclined surface 11171 and the fourth inclined surface 11172 intersect to form the tip of the reset matching protrusion 1117. The first direction intersects the first inclined surface 5151, the second inclined surface 5152, the third inclined surface 11171, and the fourth inclined surface 11172. When the first rotating member 51a rotates to a disengaged state, the second inclined surface 5152 of the reset protrusion 515a abuts against the third inclined surface 11171, so that if the first rotating member 51a wants to continue to rotate clockwise (viewed from right to left), it must squeeze the reset mating protrusion 1117 to cause the elastic arm to produce elastic deformation, thereby ensuring that the reset protrusion 515a of the first rotating member 51a cannot pass over the reset mating protrusion 1117 when there is no external force, thereby limiting the continued rotation of the first rotating member 51a. During production, workers need to check the availability of the developer cartridge 1, so they rotate the control assembly to confirm whether it can successfully cooperate with the image forming device and pass the inspection of the image forming device. When the inspection is completed, the first rotating member 51a of the control assembly has moved to a disengaged state. At this time, in order to reduce loss, the inspected developer cartridge 1 can continue to be sold after a reset operation. When resetting, it is only necessary to turn the first rotating member 51a clockwise so that the reset protrusion 515a can overcome the elastic force of the elastic arm under the action of external force, thereby crossing the reset matching protrusion 1117, and finally making the first inclined surface 5151 and the third inclined surface 11171 abut against each other, and the reset is completed. After the reset is completed, the elastic force of the elastic arm acts on the first inclined surface 5151, so that the first rotating member 51a has a slight tendency to rotate clockwise, so that when the driving portion 21a receives the power provided by the image forming device and rotates, the first rotating member 51a uses the elastic force provided by the elastic arm and the reset matching protrusion 1117, and the toothless gear 535a can easily enter the meshing state from the non-meshing state.

[0268] In this embodiment, the transmission assembly further includes an idler wheel 56b (i.e., a transmission gear), and the idler wheel 56b includes a small-diameter gear 562 and a large-diameter gear 561 that are coaxially integrally formed, and the large-diameter gear 561 is located on the left side of the small-diameter gear 562, and the large-diameter gear 561 is meshed with the driving gear, and the small-diameter gear 562 is meshed with the toothless gear 535a, and the large-diameter gear 561 is located between the plate-shaped portion 537 and the toothless gear 535a in the first direction. Thus, when the first rotating member 51a rotates, the plate-shaped portion 537 will not interfere with the idler wheel 56b. In order to simplify the installation process of the idler wheel 56b and the first rotating member 51a, the plate-shaped portion 537 is elliptical, so that the idler wheel 56b can be installed first and then the first rotating member 51a can be installed, without first assembling the first rotating member 51a and the idler wheel 56b and then installing them together on the box body 10, thereby simplifying the installation process.

[0270] Unless otherwise specified, the structure of the developer box 1 of this embodiment is the same as that of the sixteenth embodiment.

[0276] The second chip 39 further includes an insulating member 6, which is located between the battery 393 and the conductive surface, so that the electrical connection between the battery 393 and the conductive surface is blocked by the insulating member 6.

[0279] The chip support 31 includes a chip support portion and a covering portion. The chip support portion is provided with a chip support groove 311 formed by being recessed from top to bottom. A connecting hole 313 is provided on the bottom surface of the chip support groove 311. The wire 38 is connected to the chip through the connecting hole 313. The covering portion is formed by extending leftward from the chip support portion. The covering portion is used to cover the mounting groove 1118. The covering portion and the mounting groove 1118 enclose an installation space. The second chip 39 is installed in the installation space and covered by the covering portion, thereby protecting the second chip 39. The covering portion includes a covering plate 314, which is formed by extending in the first direction. The covering plate 314 covers the second chip 39 in the up and down directions. The lower surface of the covering plate 314 is fixedly provided with two downwardly protruding mounting posts 3142, and the mounting posts 3142 correspond to the mounting holes 391 one by one. When viewed from bottom to top, the circumferential surface of the mounting posts 3142 is semicircular. The covering plate 314 on one side of the mounting posts 3142 is also provided with an elastic post 3143 protruding downward, and the lower end of the elastic post 3143 is provided with a mounting protrusion 3144, and the mounting protrusion 3144 includes a mounting protrusion 3144. The inclined surface 3145 is installed, and the inclined direction of the inclined surface 3145 is set to be higher than the end close to the mounting column 3142 at the end away from the mounting column 3142, and the distance from the end of the inclined surface 3145 away from the mounting column 3142 to the center of the circumferential surface of the mounting column 3142 is greater than the radius of the mounting hole 391, and the distance from the end of the inclined surface 3145 away from the mounting column 3142 to the center of the circumferential surface of the mounting column 3142 is greater than the distance from the end of the elastic column 3143 away from the mounting column 3142 in the radial direction to the center of the circumferential surface of the mounting column 3142. Therefore, a support surface protruding from the side wall of the elastic column 3143 in the radial direction away from the mounting column 3142 is formed on the mounting protrusion 3144. When the second chip 39 is installed on the cover plate 314, the mounting hole 391 is aligned with the mounting column 3142 and the elastic column 3143 and pressed, so that the circumferential surface of the mounting hole 391 contacts and squeezes the mounting bevel 3145, so that the mounting bevel 3145 drives the elastic column 3143 to bend in the direction close to the mounting column 3142 and produce elastic deformation. When the mounting hole 391 passes through the mounting protrusion 3144, the mounting bevel 3145 and the mounting hole 391 are no longer abutted, so that the elastic column 3143 returns to its original state in the direction away from the mounting column 3142, so that the supporting surface on the mounting protrusion 3144 abuts against the lower surface of the second chip 39, thereby supporting the second chip 39 between the supporting surface and the cover plate 314, completing the positioning of the second chip 39 in the up and down directions.

[0280] The mounting post 3142 is in transitional fit with the mounting hole 391. Thus, when the mounting post 3142 and the elastic post 3143 are inserted into the mounting hole 391 together, the outer circumferential surface of the mounting post 3142 fits with the inner circumferential surface of the mounting hole 391, thereby positioning the second chip 39 in the left-right and front-back directions.

[0281] A mounting buckle 3141 is also fixedly disposed on the cover plate 314 . The mounting buckle 3141 is used to be engaged with the engaged portion 1119 on the first protective cover 111 , so that the cover plate 314 is fixed relative to the first protective cover 111 .

[0282] The insulating member 6 extends from the installation space to the outside of the space, and the pull ring 61a is located outside the installation space, so that the user can pull it out. Before the user installs the developing box 1 into the image forming device, the user pulls the pull ring 61a to pull out the insulating member 6, so that the battery 393 is electrically connected to the conductive surface, so that the battery 393 can supply power to the second chip 39, so that the second chip 39 can start to work normally.

[0283] The structures in the above embodiments can be used in combination or individually.

[0284] In summary, the above is only a preferred embodiment of the present application and is not intended to limit the scope of the present application. Through the above description, relevant staff can make various changes and modifications without departing from the technical concept of the present application. The technical scope of the present application is not limited to the contents of the specification.
