In this embodiment, the abutment member 1211 is preferably closer to the developing roller 131 than the light-emitting member 55 in the second direction. The second mounting portion 1212 is used to mount the light-emitting member 55. The third mounting portion 1213 is groove-shaped in the first direction. The third mounting portion 1213 is used to support the portion of the connecting member 53 located on the second protective cover 121, so that the connecting member 53 and the light-emitting member 55 are stably connected.

[0112] In this embodiment, according to the connection of the connecting member 53 to the conductive member, the luminous member 55 and the power supply member 54, the connecting member 53 is divided into a first connecting portion 531, a second connecting portion 532 and a third connecting portion 533. The second connecting portion 532 and the third connecting portion 533 are always connected and conductive with the luminous member 55 and the power supply member 54 respectively. The first connecting portion 531 is conductive according to whether the second conductive member 522 is in contact with the second triggering portion to determine whether the entire circuit is conductive, thereby affecting whether the luminous member 55 can emit light.

[0113] like Figure 7 and Figure 8 As shown, when the first conductive member 521 contacts the first trigger portion 500 and the second conductive member 522 contacts the first spacer block 511, the entire circuit is in an open circuit state and the light-emitting member 55 does not emit light. When the first conductive member 521 contacts the first trigger portion 500 and the second conductive member 522 contacts the first conductive block 501, the entire circuit is in a closed state and the light-emitting member 55 emits light.

[0114] According to the rotation of the rotating member 51 , whether the second conductive member 522 can contact the conductive block in the second triggering portion, and thus whether the circuit can be connected, and further whether the light-emitting member 55 can emit light.

[0115] like Fig. 9 and Fig.10 As shown, when the developing box 1 is installed on the drum assembly 20 and is located inside the image forming device, the abutting member 1211 abuts against the blocking member 21 and maintains the abutting state, so that the blocking member 21 blocks the light source emitted by the light emitting device inside the image forming device after movement, and the light source detection device inside the image forming device cannot detect the light source and generates the first signal T1. At this time, the circuit on the developing box 1 is in an open circuit state, the second conductive member 522 contacts the first spacer block 511, and the light emitting member 55 does not emit light.

[0116] When the driving part 40 receives the power output by the image forming device, and the rotating member 51 receives the power transmitted by the driving part 40 and rotates, the second conductive member 522 passes over the first spacer block 511 and contacts the first conductive block 501, so that the circuit is in a connected state, and the light-emitting member 55 emits light under the action of the electric energy released by the power supply member 54, and the light source detection device generates a second signal T2 after detecting the light source. As the rotating member 51 rotates, the second conductive member 522 continuously contacts multiple spacer blocks and conductive layers, so that the light-emitting member 55 emits light and turns off light multiple times, and the image forming device generates signals multiple times. The light-emitting and turning off process is the same as the above process, and only the length of the light-emitting time and the length of the interval are different, which will not be repeated here. The turning off mentioned in this embodiment can be that the light-emitting member 55 does not emit light at all, or the intensity of the emitted light is not enough to be detected by the light source detection device.

[0117] When the rotating member 51 stops rotating following the second idler wheel 45 , the second conductive member 522 contacts the first spacer block 511 again, the circuit is in an open circuit state, the light emitting member 55 is extinguished, and the light source detection device cannot detect the light source.

[0118] In this embodiment, the light detecting device detects the number of times and intervals of the light source and generates a signal to enable the image forming device to identify the developing box 1. This embodiment does not limit the number of times and duration of light emission, which can be set according to actual needs.

[0119] Embodiment 2:

[0120] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment. The difference between this embodiment and the first embodiment lies in the different structure of the detected component.

[0121] like Figure 11-Figure 14 As shown, in this embodiment, the rotating member 46 receives the power transmitted by the stirring gear 44 and rotates, and its rotation axis extends in a first direction. The rotating member 46 includes a gear portion 461, an abutment portion 462 and a recessed portion 463. The gear portion 461 is toothless and can be engaged with the stirring gear 44 and rotate, or it can be disengaged from the stirring gear 44 and no longer rotate. In the first direction, the abutment portion 462 is closer to the second end 12 than the gear portion 461, and the recessed portion 463 is recessed in the radial direction of the rotating member 46, and the recessed portion 463 and the abutment portion 462 form a complete circle. The recessed portion 463 is provided with a slope 4631, and the slope 4631 can also be an arc surface.

[0122] In this embodiment, the detected component includes a power supply 54 and a light emitting component 55, which are the same as those in the first embodiment and are not described in detail here. The detected component also includes a connecting component 53, a switch component 56 and a control unit 57. The connecting component 53 is preferably a conductive steel sheet or a wire, and the connecting component 53 is used to connect the remaining components in the detected component to form a conductive circuit, thereby making the light emitting component 55 emit light so that the light source detection device detects a signal.

[0123] The box body 10 is provided with a support portion 106, which is a cylindrical protrusion extending in the second direction. The switch member 56 is a swing member. The switch member 56 is provided with a supported portion 563 which is a circular hole. The switch member 56 and the support portion 106 are matched by the shaft hole so that the switch member 56 is rotatably supported by the box body 10, and the rotation axis of the switch member 56 extends in the second direction. The switch member 56 also includes a trigger end (i.e., a switch portion) and an abutted end 562, which are respectively located at the two ends of the switch member 56 in the first direction, and the trigger end is closer to the second end 12 than the abutted end 562, and the supported portion 563 is located between the two. The trigger end includes a first trigger portion 5611 and a second trigger portion 5612 which are protruding, and the two are arranged one on the left and one on the right in the first direction. Preferably, the first trigger portion 5611 is farther away from the second end 12 than the second trigger portion 5612. The abutted end 562 is used to contact the rotating member 46 to make the switch member 56 swing relative to the box body 10. When the abutted end 562 is located in the recessed portion 563 of the switch member 56, the trigger end is in a raised state, and when the abutted end 562 abuts against the abutting portion 462, the trigger end is in a depressed state. At least the trigger end of the switch member 56 is made of a conductive material, and the entire switch member 56 may also be made of a conductive material.

[0124] The control unit 57 includes a control module and a storage module. The storage module stores a program for controlling the light-emitting element 55 to emit light or turn off. The control module executes the program and outputs an electrical signal for controlling the light-emitting element to emit light or turn off. When the control unit 57 and the circuit where the light-emitting element 55 is located are connected, the light-emitting element 55 emits light or turns off according to the instruction of the control unit 57. The duration and number of times of the light-emitting and turning off are controlled by the control unit 57.

[0125] The connector 53 is provided with a first connection portion 591 and a second connection portion 592 near the first end 11. The first connection portion 591 has a certain elasticity. The first connection portion 591 and the second connection portion 592 are not in direct contact and are arranged on the left and the right in the first direction. In the first direction, the second connection portion 592 is closer to the second end 12 than the first connection portion 591. The first connection portion 591 and the second connection portion 592 are in contact with the first trigger portion 5611 and the second trigger portion 5612 respectively. When the first connection portion 591 is in contact with the first trigger portion 5611 and the second connection portion 592 is in contact with the second trigger portion 5612, that is, when the trigger end is in a downward pressure state, the connector 53 connects the entire detected component into a conductive loop, and the light-emitting component 55 receives the electric energy released by the power supply component 54 and emits and extinguishes light under the command issued by the control unit 57. That is, the first connection portion 591 and the second connection portion 592 in this embodiment can be regarded as the first conductive member and the second conductive member respectively, or they can be conductive members separately provided to be in electrical contact with the switch member as in the first embodiment.

[0126] When the developing box 1 does not receive the power output by the image forming device, the abutted end 562 is in the recessed portion 463 of the rotating member 46, the triggering end is in a raised state, at least the second connecting portion 592 is not in contact with the second triggering portion 5612, the entire circuit is in an open circuit state, and the light-emitting member 55 does not emit light.

[0127] When the driving part 40 receives the power output by the image forming device and transmits the power to the rotating member 46 to rotate the rotating member 46, the abutted end 562 abuts against the inclined surface 4631 of the recessed portion 463 and gradually disengages from the recessed portion 463, and the switch member 56 rotates relative to the box body 10. When the recessed portion 463 disengages from the abutting portion 562, the triggering end is in a downward pressure state, the first connecting portion 591 contacts the first triggering portion 5611 and the second connecting portion 592 contacts the second triggering portion 5612, thereby making the entire circuit conductive, the light-emitting member 55 emits light, and the first connecting portion 591 is squeezed by the first triggering portion 5611 and has elastic force.

[0128] When the rotating member 46 continues to rotate, the light-emitting member 55 switches between emitting light and extinguishing light. When the rotating member 46 is disengaged from the stirring gear 44 and no longer rotates, the detection ends, the abutted end 562 returns to the recessed portion 463 again, and the first connecting portion 591 releases the elastic force to make the switch member 56 swing in the opposite direction so that the trigger end is in a lifted state, at least the second connecting portion 592 does not contact the second triggering portion 5612, and the entire circuit is in an open circuit state. Alternatively, a separate elastic member may be provided to make the switch member 56 swing in the opposite direction, or to make the weight of the abutted end 562 greater than the weight of the triggering end, so that the abutted end 562 drives the switch member 56 to swing again under the influence of gravity.

[0129] In this embodiment, the rotating member 46 controls the switch member 56 to move between the on position and the off position, and the control unit 57 is started and / or terminated by the switch member 56. The control unit 57 generates an electrical signal to control the light-emitting member 55 to emit light or extinguish. That is, the rotating member 46 in this embodiment serves as a detected member that controls the on and off of the circuit.

[0130] Embodiment three:

[0131] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment. The difference between this embodiment and the first embodiment is that the detected component further includes a light guide 61 .

[0132] like Figure 15-17 As shown, the light emitting element 55 receives the electric energy released by the power supply element 54 to emit light, and the light emitted by the light emitting element 55 is not directly received by the light source detection device 201, but is indirectly transmitted to the light source detection device through the light guide 61.

[0133] In this embodiment, the light-emitting component 55 is arranged on the box body 10, preferably at the fifth end 15, and the distance between the light-emitting component 55 and the second end 12 in the first direction is smaller than the distance between the light-emitting component 55 and the first end 11, that is, the light-emitting component 55 is supported by the box body 10, so that the connecting component 53 connected to the light-emitting component 55 also only needs to be arranged on the box body 10, thereby simplifying the structure and installation difficulty of the connecting component 53, and in some embodiments, it may also be supported by the second protective cover 121.

[0134] The second protective cover 121 is provided with a mounting groove 1214 extending in the first direction, and the light guide 61 is at least partially located in the mounting groove 1214. The light guide 61 is preferably fixedly installed in the mounting groove 1214 in a snap-fit ​​manner. The light guide 61 is preferably a light guide column, and the light guide 61 includes a light receiving portion 611 and a light transmitting portion 612. In the first direction, the light receiving portion 611 is closer to the first end 11 than the light transmitting portion 612. The light receiving portion 611 is a column extending in the first direction, and the light receiving portion 611 is disposed adjacent to the light emitting member 55. A light inlet is disposed on the light receiving portion 611, and the light inlet receives the light source emitted by the light emitting member 55. In the first direction, the light transmission part 612 is farther away from the light emitting part 55 than the light receiving part 611. The two are preferably formed in one piece, or they can be a combination of separate parts. The light transmission part 612 is protrudingly arranged on the basis of the light receiving part 611, and the junction of the two is curved or broken line-shaped. The light transmission part 612 protrudes upward in the third direction and protrudes forward in the second direction, that is, the extension direction of the light transmission part 612 intersects with the second direction and the third direction. A light outlet is provided on the light transmission part 612, and the light outlet is used to transmit the light source received by the light guide 61 to the outside. The light inlet of the light receiving part 611 receives the light source emitted by the light emitting part 55, and transmits the light source to the light transmission part 612 by reflection inside the light guide 61, so that the light source is emitted from the light outlet along the X direction and transmitted to the light source detection device 201.

[0135] The light guide 61 is also provided with a buckle, so that the light guide 61 can be stably disposed on the second protective cover 121 . In some embodiments, the light guide 61 can also be supported by the box body 10 or supported by both the box body 10 and the second protective cover 121 .

[0136] like Fig.18 As shown, in some embodiments, the light emitting member 55 can be arranged adjacent to the first end 11, that is, the distance between the light emitting member 55 and the second end 12 in the first direction is greater than the distance between the light emitting member 55 and the first end 11, and the length of the light receiving portion 611 in the first direction is increased so that the light guide member 61 can stably receive the light transmitted by the light emitting member 55. This structure can further simplify the structure of the circuit where the light emitting member 55 is located, and reduce the production cost of the developing box 1. At the same time, it can be shown that the position of the light emitting member 55 in this embodiment has no effect on whether the light emitting member 55 stably transmits the light source to the light source detection device, and the position of the light emitting member 55 can be set according to actual needs.

[0137] Embodiment 4:

[0138] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the third embodiment. The difference between this embodiment and the third embodiment lies in the different structure of the light guide member.

[0139] like Figure 19-20As shown, in this embodiment, the light guide 61 is a light guide plate, and a light guide surface 610 is provided on the light guide 61. The light guide surface 610 can be a mirror surface or other surfaces with a reflective function. The extension direction of the light guide surface 610 is inclined relative to the first direction, the second direction, and the third direction, that is, the light guide surface 610 extends to the left in the first direction, extends forward in the second direction, and extends upward in the third direction. In this embodiment, the intersection angle of the light guide surface 610 and the first direction, the second direction, and the third direction is not limited, and the light source can be fully or partially transmitted to the light source detection device 201.

[0140] When the light emitting element 55 emits light, the light is transmitted to the light guide surface 610 along the X1 direction. In this embodiment, the X1 direction is preferably parallel to the first direction, but can also be inclined relative to the first direction. After receiving the light, the light guide surface 610 emits the light, and then the light is reflected to the light source detection device 201 along the X2 direction, which intersects the X1 direction.

[0141] In this embodiment, the light emitting element 55 can be disposed near the second end 12 , or the light emitting element 55 can be disposed near the first end 11 on the basis of stably transmitting the light source to the light guiding surface 610 to further simplify the structure of the circuit in which the light emitting element 55 is located.

[0142] Embodiment five:

[0143] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment. The difference between this embodiment and the first embodiment lies in the structure of the power supply. In this embodiment, the developing box 1 does not need to be provided with a power supply with its own electrical energy.

[0144] like Figure 21-24 As shown, an electric transmission component is provided on the developing box 1, and the electric transmission component is used to electrically connect with the connecting component 53 and the electrode 102, so that the connecting component 53 receives the electric energy transmitted by the electrode 102, and then the light-emitting component 55 receives the electric energy and emits light, that is, the electrode can be regarded as the power supply component in this embodiment, which meets the electric energy demand of the light-emitting component 55 when emitting light.

[0145] A bearing 103 is provided at the second end 12, and the bearing 103 rotatably supports the end of the developing roller 131 and the powder feeding roller at the second end 12.

The electrode 1021 transmits electric energy to the developing roller 131 and the powder feeding roller, and is electrically connected to the connecting member 53 through the electric transmission member to provide electric energy.

[0146] In this embodiment, in order to reasonably set the installation and arrangement of the electric transmission parts, the electric transmission parts preferably include a first electric transmission part 63 and a second electric transmission part 64.

One end of the second electric transmission part 64 is in contact with the first electric transmission part 63, and the other end is in contact with the connecting part 53, so that the first electric transmission part 63 will receive the electric energy from the electrode 102 and transmit it to the connecting part 53 through the second electric transmission part 64, so that the circuit where the light-emitting part 55 is located can receive external electric energy, and then meet the electric energy demand of the light-emitting part 55 when the circuit is in the passage, so as to ensure that the light-emitting part 55 stably emits light and the light source detection device 201 detects the light source. The electric transmission member may be formed integrally with the connecting member 53, that is, the connecting member 53 is in direct electrical contact with the electrode 102, or the electric transmission member is in direct contact with the power supply terminal on the image forming device to receive electrical energy, and the electric transmission member serves as a power supply member.

[0147] In this embodiment, a grounding member 62 is also provided. The grounding member 62 is used to enable the circuit where the light-emitting member 55 is located to form a complete loop, thereby ensuring the safety and stability of the circuit. In this embodiment, the grounding member 62 is preferably provided close to the first end 11, that is, the distance between the grounding member 62 and the second end 12 in the first direction is greater than the distance between the grounding member 62 and the first end 11. One end of the grounding member 62 contacts the trigger portion, and the other end contacts the outside of the developing box 1, preferably contacts the metal parts in the image forming device. In this embodiment, the grounding member 62 is preferably a conductive elastic member such as a spring. The conductive elastic member can elastically avoid the interfering parts in the image forming device during the process of installing the developing box 1 in the image forming device, which can not only ensure that the developing box 1 is stably installed in the image forming device, but also can stably contact the metal parts in the image forming device after being installed in the image forming device.

[0148] The developing roller 131 includes a developing roller shaft and a developing body, the developing roller shaft drives the developing body to rotate, and the developing body is made of conductive rubber.

[0150] Embodiment six:

[0151] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the fifth embodiment. The difference between this embodiment and the fifth embodiment lies in the different structure of the power supply.

[0152] like Figure 25-26 As shown, the electrical contact surface on the storage medium 101 in this embodiment provides electrical energy to the circuit where the light-emitting element 55 is located, that is, the electrical contact surface serves as the power supply element of this embodiment. The connecting element 53 includes a first line 534 and a second line 535, and the first line 534 and the second line 535 connect the power supply element, the light-emitting element 55 and the conductive element together to form a circuit.

[0153] The storage medium 101 is provided with a plurality of electrical contact surfaces, and the electrical contact surfaces are electrically connected to the storage medium 101. The electrical contact surfaces include a first electrical contact surface and a second electrical contact surface, which are arranged at intervals. The first line 534 contacts the first electrical contact surface, and the second line 535 contacts the second electrical contact surface. The first line 534 is used to receive the electric energy emitted by the first electrical contact surface, and allows the electric energy to return to the second electrical contact surface after passing through the light-emitting element 55, the conductive element, and the second line 535. That is, in this embodiment, the first electrical contact surface can be regarded as the positive electrode of the battery, and the second electrical contact surface can be regarded as the negative electrode of the electrode.

[0154] In one embodiment, the first electrical contact surface 1011 serves as a power supply to receive external electrical energy and transmits it to the light-emitting element 55 through the first line 534, and the second line 535 serves as a grounding element to contact the external component to realize a circuit loop.

[0155] In another embodiment, the rotating member 51 and the conducting member are not required, the circuit itself is a complete loop, and the storage medium 101 stores first information and second information, the first information is information for controlling the light-emitting duration and light-emitting interval of the light-emitting member 55, and the second information is other information about the developing box 1. After the developing box 1 is installed in the image forming device, the electrical contact surface of the storage medium 101 provides power to the light-emitting member 55 and acts as a control unit to control the light-emitting member 55 to emit light at an appropriate time, so that the light source detection device 201 detects the light source and the image forming device generates a signal.

[0156] Embodiment seven:

[0157] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment. The difference between this embodiment and the first embodiment lies in the different structure of the triggering part.

[0158] like Figure 27-Figure 30 As shown, the detected component in this embodiment includes a rotating part 60, a switch part 71, a connecting part 53, a power supply part 54 and a light-emitting part 55. The connecting part 53 connects the switch part 71, the power supply part 54 and the light-emitting part 55 in a circuit. The connecting part 53, the power supply part 54 and the light-emitting part 55 are the same or similar to the above-mentioned embodiments and are not repeated here.

[0159] The switch member 71 is preferably arranged near the first end 11. The switch member 71 is used as a switch to determine whether the circuit where the light-emitting member 55 is located forms a path. A support member 107 is arranged on the box body 10. The support member 107 includes a support column 1070 and a fixing buckle 1071. The support column 1070 extends in the third direction. The fixing buckle 1071 is an elastic buckle. Preferably, there are multiple support columns 1070 and fixing buckles 1071. The switch member 71 includes a first hole 710. The first hole 710 is preferably a through hole extending in the third direction. The number of the first holes 710 matches the support column 1070.

The fixing buckle 1071 is clamped at both ends of the switch member 71 in the second direction to further stabilize the switch member 71. In other embodiments, the switch member 71 can be fixed to the box body 10 by welding or screws.

[0160] The switch member 71 further includes a first terminal 712, a second terminal 713 and a triggering part 72. The first terminal 712 is connected to the power supply member 54 through the connecting member 53, and the second terminal 713 is connected to the integrated board 550 through the connecting member 53. The triggering part 72 is a protrusion protruding in the first direction. The triggering part 72 is movably mounted on the main body of the switch member 71, and further moves relative to the main body of the switch member 71 in the first direction. The switch member 71 includes a second hole 711 extending in the first direction, and the second hole 711 is preferably a blind hole. The triggering part 72 is at least partially movably located in the second hole 711.

There are a first position and a second position in the first direction, and the first position is farther away from the second end 12 than the second position. When the trigger part 72 is in the second position, the circuit path of the light emitting member 55 is open, and the light emitting member 55 emits a light source (the light source may be infrared light or other types of light sources); when the trigger part 72 is in the first position, the circuit of the light emitting member 55 is disconnected, and the light emitting member 55 does not emit a light source. When the trigger part 72 is acted upon by an external force, the trigger part 72 moves in the first direction toward the second end 12 to move from the first position to the second position, and the first elastic member 720 is compressed and continues to exert elastic force; when the external force disappears, the trigger part 72 moves in the first direction toward the first end 11 under the action of the first elastic member 720 to move from the second position to the first position.

[0161] The rotating member 60 is rotatably disposed at the first end 11. The rotating member 60 receives power transmitted by the transmission assembly to rotate, and the rotation axis of the rotating member 60 extends in the first direction. The rotating member 60 includes a meshing portion 600 and an abutting protrusion. The meshing portion 600 is toothless. The meshing portion 600 meshes with the stirring gear 44 so that the rotating member 60 receives power and rotates. The toothless structure can disengage the meshing portion 600 from the stirring gear 44 to stop the rotating member 60 from rotating.

[0162] The abutting protrusion is used to abut against the triggering part 72 and drive the triggering part 72 to move in the first direction. The abutting protrusion protrudes in the first direction and is provided in plurality. Preferably, the abutting protrusion includes a first abutting protrusion 601, a second abutting protrusion 602 and a third abutting protrusion 603 arranged at intervals in the rotation direction of the rotating member 60. In the rotation direction of the rotating member 60, the first abutting protrusion 601, the second abutting protrusion 602 and the third abutting protrusion 603 abut against the triggering part 72 in sequence and make the triggering part 72 move in the first direction toward the second end 12. In order to make the abutment between the abutting protrusion and the triggering part 72 smoother, the first abutting protrusion 601, the second abutting protrusion 602 and the third abutting protrusion 603 are all provided with abutting surfaces of inclined surfaces or arc surfaces, and the extending direction of the abutting surfaces intersects with the first direction. Similarly, an inclined surface may also be provided on the triggering part 72. The arc lengths corresponding to the first abutting protrusion 601 , the second abutting protrusion 602 and the third abutting protrusion 603 may be the same or different, and the angles between the abutting surfaces thereon and the first direction may be the same or different, which can be set according to actual needs.

[0163] like Fig.29 As shown, the rotating member 60 receives the power transmitted by the transmission assembly and rotates, the first abutment protrusion 601 abuts against the trigger portion 72 and is in the second position, the light-emitting member 55 is in the circuit path, the light-emitting member 55 receives the electric energy released by the power supply member 54 and emits light, and the light source detection member 201 detects the light source.

[0164] When the trigger portion 72 is located at the interval between the first abutting protrusion 601 and the third abutting protrusion 603 , the trigger portion 72 is located at the first position under the action of the first elastic member 720 , and the circuit where the light emitting member 55 is located is disconnected.

[0165] That is, when the first abutment protrusion 601, the second abutment protrusion 602 and the third abutment protrusion 603 abut against the trigger part 72, the trigger part 72 is in the second position and the circuit is open; when the trigger part 72 is located at the interval (i.e., in the second position) under the action of the first elastic member 720, the circuit is open.

[0166] It can be known that the length of time that the light-emitting component 55 emits light can be determined according to the arc length of the abutment protrusion, the interval time of the light-emitting component 55 emits light can be determined according to the interval between the abutment protrusions, the number of times the light-emitting component 55 emits light can be determined according to the number of abutment protrusions, and the speed at which the light-emitting component 55 emits light can be determined according to the moving speed of the trigger part 72 (i.e., the inclination degree of the abutment slope).

[0167] That is, in this embodiment, a plurality of abutment protrusions abut against the trigger portion 72 in turn and break away from the abutment with the trigger portion 72 to complete the circuit connection and disconnection, thereby making the light-emitting element 55 emit light and extinguish multiple times, thereby meeting the needs of the image forming device.

[0168] like Fig. 27 As shown, in this embodiment, the light emitting component 55 is located on an integrated board 550 , and the integrated board 550 is connected to the connecting component 53 .

[0169] In another embodiment, the trigger portion 72 moves in a swinging manner after being abutted by the abutting protrusion, thereby opening a circuit path where the light-emitting element 55 is located.

[0170] like Fig.30 As shown, in other embodiments, the trigger portion 72 does not directly contact the abutting protrusion. The switch member 71 is also provided with an intermediate member 73, and the trigger portion 72 is located between the intermediate member 73 and the abutting protrusion. The intermediate member 73 is abutted by the abutting protrusion to move and drive the trigger portion 72 to move. The intermediate member 73 is plate-shaped, one end of which is fixedly connected to the main body of the switch member 71, and the other end is provided with an abutted protrusion 730. The abutting protrusion abuts the abutted protrusion 730 to make the intermediate member 73 swing, thereby making the intermediate member 73 drive the trigger portion 72 to move in the first direction toward the second end 12.

[0171] The switch element 71 in this embodiment is a micro switch.

[0172] Embodiment eight:

[0173] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the seventh embodiment. The difference between this embodiment and the seventh embodiment lies in the different structure of the detected component.

[0174] like Figure 31-Figure 37 As shown, the detected component in this embodiment includes a control unit 70, a rotating member 60, a switch member 71, a connecting member 53, a power supply member and a light-emitting member 55. The rotating member 60 controls the closing and opening of the switch member 71 to control whether the circuit where the light-emitting member 55 is located is turned on. The switch member 71 includes a first terminal 712, a second terminal 713 and a triggering part 72. The first terminal 712 and the second terminal 713 are connected to the control unit 70 through the connecting member 53 respectively.

[0175] The control unit 70 is preferably an integrated circuit board, i.e., an IC chip, which stores information such as the number of times and duration of the light-emitting member 55. The control unit 70 controls the light-emitting member 55 to emit light and determines the number of times and duration of the light-emitting member 55 within a predetermined time. That is, in this embodiment, the number of times and duration of the light-emitting member 55 are not controlled by the number of times the rotating member 60 abuts against the switch member 71. In this embodiment, only one abutting protrusion may be provided, or only the end face of the rotating member 60 abuts against the switch member 71. In one embodiment, the rotating member 60 may move in the first direction and abut against the switch member 71 with the end face. In this embodiment, the light-emitting member 55 is provided on the control unit 70 and electrically connected to the control unit 70 by welding or plugging. Further, the light-emitting member 55 is located on the upper end face of the control unit 70 facing upward in the third direction, and is located on the side of the control unit 70 away from the first end 11 in the first direction and on the side away from the developing roller 131 in the second direction, i.e., the light-emitting member 55 is located at the left rear position of the control unit 70. In the second direction, the distance L1 between the light emitting member 55 and the rotation axis of the developing roller 131 is between 50 mm and 75 mm, and is preferably 62.5 mm in this embodiment. In the first direction, at least part of the electrode 102 is closer to the first end 11 than the light emitting member 55 .

[0176] When the developing box 1 is installed in the image forming device, in the second direction, the light source detection device 201 in the image forming device is located in front of the light emitting member 55, so the light emitting direction X of the light emitting member 55 (i.e., the main direction of the light emitted by the light emitting member 55) intersects with the second direction and the third direction. In this embodiment, the angle A1 between X and the second direction is 20° to 80°, and the preferred angle A1 in this embodiment is 63°. In some embodiments, the light emitting direction of the light emitting member 55 can be directly parallel to the third direction, or the light emitting member 55 can be moved forward to the bottom or front of the light source detection member 201, and the light source can be transmitted to the light source detection device, that is, the angle of the angle A1 can change according to the change of the size of L1, and this embodiment does not make a specific limitation.

[0177] The control unit 70 further includes a writing unit 701, a first connection port 702, a storage module 703 and a control module. The writing unit 701 and the first connection port 702 are both located at the same end face of the control unit 70 as the light-emitting element 55. The writing unit 701 is a plurality of metal surfaces. The writing unit 701 is used to contact with external components to input information such as the number of times and duration of light emission of the light-emitting element 55 into the control unit 70. The storage module 703 is used to store the program written by the writing unit 701 and send the program within a predetermined time. The storage module usually adopts a flash memory chip or an EEPROM (Electrically Erasable Programmable readonly memory). The control module executes the program and outputs an electrical signal for controlling the light-emitting element to emit light or turn off. The control module can adopt a microcontroller (MCU) or a programmable logic controller (PLC). The connecting member 53 is fixed by a first plug-in member 74, and the first plug-in member 74 is inserted into the first connection port 702 to realize the electrical connection between the control unit 70 and the switch member 71. In this embodiment, the control unit 70 can be regarded as a second storage medium different from the storage medium 101.

[0178] In this embodiment, the power supply is electrically connected to the control unit 70, and is electrically connected by electrical contact. The power supply is preferably a button battery. In this embodiment, the power supply includes a first power supply 751 and a second power supply 752 with a specification of 1.5V. In some embodiments, only one power supply with a specification of 3V may be provided. The first power supply 751 and the second power supply 752 are in electrical contact with the lower end surface of the control unit 70 facing downward in the third direction to transfer electrical energy, that is, the light-emitting element 55 of the embodiment and the power supply are located on different end surfaces of the control unit 70 in the third direction. In order to prevent the power supply from being out of contact with the control unit 70, a limiting member is also provided. The limiting member is fixedly connected to the control unit 70 by welding or gluing, and the power supply is located between the limiting member and the lower end surface to be limited.

[0179] In this embodiment, the limiting member includes a first limiting member 753 and a second limiting member 754, which respectively limit the first power supply member 751 and the second power supply member 752. The limiting member is preferably a steel sheet, the positive electrode of the power supply member contacts the lower end surface of the control unit 70, and the negative electrode contacts the limiting member.

[0180] The control unit 70 is also provided with other electronic components such as resistors, capacitors and transistors located at the lower end surface to form a complete electronic system. This embodiment does not limit the specific positions of the electronic components and can be set according to actual needs.

[0181] A mounting member 58 is also provided at the second end 12. The mounting member 58 is used to support the control unit 70. The mounting member 58 is combined with the control unit 70 by snapping. The mounting member 58 at least covers the upper end surface of the control unit 70 to protect the control unit 70. The mounting member 58 is provided with an exposure hole 581. The exposure hole 581 is used to expose the light emitting member 55 so that the light emitted by the light emitting member 55 can be detected by the light source detection device. When the mounting member 58 is snapped with the control unit 70, the mounting member 58 is fixedly connected with the second protective cover 121 by snapping or screwing, and can also be fixedly connected with the box body 10.

[0182] In this embodiment, the connector 53 is at least partially located at the fourth end 14, that is, the connector 53 is connected to the switch 71 and extends in the second direction before bending and extending to the left in the first direction to the second end 12, and then electrically connected to the control unit 70. This structure can beautify the wiring of the connector, hide the connector 53 at the fourth end 14 to prevent the connector 53 from being interfered with by external components. A receiving portion can be provided at the fourth end 14 to accommodate the connector 53, or a mounting buckle can be provided to support the connector 53.

[0183] When the rotating member 60 receives the power transmitted by the driving part 40 and rotates, the rotating member 60 abuts against the switch member 71 to make it in a closed state, and the light-emitting member 55 emits light and turns off under the control of the control unit 70, so that the light source detection device detects the light source and generates a signal. When the rotating member 60 no longer rotates, the rotating member 60 is disengaged from the abutment with the switch member 71, the switch is disconnected, and the control unit 70 stops issuing instructions to the light-emitting member 55, and the light-emitting member 55 turns off. That is, in this embodiment, the rotating member 60 serves as a detected member, which is used to cause the switch member 71 to close so that the control unit 70 issues instructions.

[0184] In one embodiment, the rotating member 60 can be in constant contact with the switch member 71 from no contact. That is, the switch member 71 does not need to be opened again after being opened and closed. The command issued by the control unit 70 will only cause the light-emitting member 55 to change between lighting and extinguishing within a certain period of time. The closing of the switch member 71 only transmits a signal to the control unit 70 to start issuing commands.

[0185] It can be known that in this embodiment, the control unit 70 can issue instructions to the light-emitting component 55 multiple times, that is, when the rotating component 60 is engaged with the stirring gear 44 again to receive power and rotate, when the rotating component 60 triggers the switch component 71 again, the control unit 70 can issue instructions to the light-emitting component 55 again.

[0186] like Fig.38As shown, in this embodiment, the stirring rack is no longer provided, and the bottom wall 161 of the box body 10 is inclined relative to the second direction. The bottom wall 161 extends forward in the second direction and extends downward in the third direction. There is an angle A2 between the bottom wall 161 and the second direction, and the angle A2 is 20° to 70°. In this embodiment, A2 is preferably 46°, and can also be 35°. Under the influence of gravity, the developer in the box body 10 flows along the extension direction of the bottom wall 161, that is, flows toward the developing roller 131 and the powder feeding roller. This structure can ensure that the developing roller 131 and the powder feeding roller can stably absorb the developer when the stirring rack is eliminated. A reinforcing column 108 is also provided in the box body 10, and the reinforcing column 108 extends in the third direction. The reinforcing column 108 is located between the two ends of the cover of the box body 10 in the second direction.

[0187] like Fig.37 and Fig.38 As shown, a powder filling port 122 is also provided at the second end 12, and the developer 122 is poured into the box body 10 through the powder filling port 122. In the third direction, the bottom wall 161 is at least partially located below the powder filling port 122. In the second direction, the powder filling port 122 is located between the light emitting member 55 and the developing roller 131, and the powder filling port is located between the rotating member 60 and the driving part 40. When viewed from the first direction, the reinforcing column 108 at least partially overlaps with the powder filling port 122.

[0188] like Fig.38 As shown, the developing box 1 further includes a cover plate 163 and a storage medium 101. The cover plate 163 extends in the first direction and is fixedly arranged at the sixth end 16 by means of a buckle or a screw. A mounting portion 1631 for mounting the storage medium 101 is provided on the cover plate 163, and the mounting portion 1631 extends in the first direction and is located at the first end 11.

[0189] The developing box 1 further comprises a bearing 103 and a connecting plate 104 mounted on the second end 12, the bearing 103 is located at the front end of the box body 10 in the second direction, the second protective cover 121 is located at the rear end of the box body 10 in the second direction, the connecting plate 104 is mounted on the outer side of the second protective cover 121 and the bearing 103, and the rear end of the bearing 103 and the front end of the second protective cover 121 are fixed to the box body 10 through the connecting plate 104. The front end of the bearing 103 is fixedly connected to the box body 10 through a buckle, the rear end of the second protective cover 121 is fixedly connected to the box body 10 through a buckle or a screw, the front end of the connecting plate 104 fixes the rear end of the bearing 103 to the box body 10 through a screw, and the rear end of the connecting plate 104 fixes the rear end of the front end of the second protective cover 121 to the box body 10 through a screw.

[0190] like Fig.35 and Fig.36As shown, the box body 10 of the developer box 1 includes an upper cover 10a and a lower cover 10b, which are welded together to form a receiving chamber for receiving the developer. The cover plate 163 is installed on the bottom surface of the lower cover 10b and can be connected by buckles or screws.

[0191] The box body 10 of the developing box 1 further includes a protective cover 10c, which extends in the first direction. The upper cover 10a is provided with a receiving portion 10a1 for receiving the connecting member 53 at the rear end in the second direction, and the receiving portion 10a1 is recessed downward relative to the upper surface of the upper cover 10a. The protective cover 10c is mounted on the receiving portion 10a1 to protect the connecting member 53.

[0192] A protection portion 10c1 for protecting the switch component 71 is provided at one end of the protection cover 10c. After the protection cover 10c is mounted on the upper cover 10a, the protection portion 10c1 covers the switch component 71 to protect the switch component 71 from damage.

[0193] Embodiment nine:

[0194] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment, and the structure of the switch member in this embodiment is different from that in the eighth embodiment.

[0195] like Fig.39 and Fig.40 As shown, in this embodiment, the switch element is a storage medium 101, one end of the connecting member 53 is electrically connected to the control unit 70, and the other end is electrically connected to the storage medium 101. When the developing box 1 is installed in the image forming device, and the electrical contact surface of the storage medium 101 is electrically contacted with the electrical contact pin in the image forming device, the control unit 70 receives a signal transmitted by the storage medium 101 through the connecting member 53, and the signal causes the control unit 70 to start issuing an instruction to control the light-emitting element 55 to emit light and turn off. That is, the role of the switch element in this embodiment is no longer to determine the conduction and disconnection of the circuit where the light-emitting element 55 is located, but to send a signal to the control unit 70 to start outputting instructions. The circuit where the light-emitting element 55 is located is always in the conducting state, and the instructions issued by the control unit 70 cause the light-emitting element 55 to change between emitting light and turning off within a period of time, rather than always being in the state of alternating between emitting light and turning off. A second plug-in 742 is provided on the developing box 1, and one end of the connecting member 53 is connected to the first plug-in 74, and the other end is connected to the second plug-in 742. The storage medium 101 is provided with a second connection port 1011 , and the second plug-in component 742 is inserted into the second connection port 1011 to electrically connect the storage medium 101 to the connection component 53 , and further to electrically connect the storage medium 101 to the control unit 70 .

A first receiving groove extending in the first direction may be provided at the sixth end 16 and a second receiving groove extending in the third direction may be provided at the second end 12 to install the connecting member 53.

[0197] The electrode 102 can also be used as a signal source to trigger the control unit 70. After the electrode is energized, an electrical signal is released to the control unit 70 through the connector 53. After the control unit 70 collects the electrical signal, it starts to control the light-emitting element 55 to turn on and off.

[0198] A voltage reduction unit may be further provided between the electrode 102 and the connector 53 , and the voltage reduction unit reduces the external electrical energy received by the electrode 102 to electrical energy adapted by the control unit 70 .

[0199] The cover plate 163 at least covers a portion of the connecting member 53 to protect the portion of the connecting member 53 located at the sixth end 16 .

[0200] In this embodiment, a reset part can also be set on the control unit 70. The reset part is preferably a metal surface. When the control unit 70 needs to issue instructions to the light-emitting component 55 again, the metal component can be used to contact the reset part and the writing part 701 at the same time, even if the two are electrically connected, the control unit 70 can be reset.

[0201] The storage medium 101 in this embodiment may also be disposed on the cover plate 163 .

[0202] A rib 162 is further provided at the sixth end 16 . The rib 162 is used to strengthen the strength of the box body 10 . The rib 162 is also covered by the cover plate 163 .

[0203] Compared with the above-mentioned embodiments, the present embodiment further simplifies the structure of the detected component, and only needs to provide a driving portion 40 , a developing gear 41 and a powder feeding gear 42 , further simplifying the structure and cost of the developing box 1 .

[0204] Embodiment ten:

[0205] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment, and the structure of the switch member in this embodiment is different from that in the eighth embodiment.

[0206] like Figure 41-43 As shown, in this embodiment, the switch member 63 is arranged at the fourth end 14, preferably and arranged close to the second end 12 in the first direction, which can save the length of the connecting member 55. The developing box 1 is also provided with a sliding member 66, which can slide relative to the box body 10 in the second direction. In the second direction, the sliding member 66 is farther away from the developing roller 131 than the switch member 71, and the sliding member 66 is used to abut against the contact portion 73 to make the switch member 61 in a closed state.

[0207] The box body 10 is provided with a support protrusion 109 extending in the third direction, the support protrusion 109 is columnar, the support protrusion 109 can movably support the sliding member 66, the support protrusion 109 includes a through hole penetrating in the second direction, the sliding member 66 is inserted into the through hole to be slidably connected with the support protrusion 109. A second elastic member 661 is provided between the support protrusion 208 and the sliding member 66, preferably the second elastic member 661 is a compression spring, and the elastic member 66 is used to prevent the sliding member 66 from sliding forward in the second direction.

[0208] When the developing cartridge 1 is mounted on the image forming device, but the door cover 202 of the image forming device is not closed, the switch member 71 is in an off state, and the control unit 70 cannot issue a command to make the light emitting member 55 emit light. When the door cover 202 begins to gradually close, the door cover 202 abuts against one end of the sliding member 66 so that the sliding member 66 overcomes the elastic force of the second elastic member 661 and slides forward in the second direction, and the other end of the sliding member 66 abuts against the triggering portion 73 so that the switch member 71 is closed. At this time, the control unit 70 issues a command to switch the light emitting member 55 between emitting light and extinguishing light within a predetermined time.

[0209] Embodiment eleven:

[0210] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment, and the structure of the switch member in this embodiment is different from that in the eighth embodiment.

[0211] like Fig.44 and Fig.45 As shown, in this embodiment, the switch member is an insulating member 76, and the insulating member 76 is preferably an insulating belt. The insulating member 76 extends in a first direction, one end of the insulating belt 76 is fixedly connected to the rotating member 60, and the other end is located between the lower end surfaces of the power supply member and the control unit 70 to isolate the two and prevent the two from being electrically connected.

[0212] A connecting protrusion 604 is provided on the rotating member 60, and a hole portion is provided on the insulating member 76. The hole portion is combined with the connecting protrusion 604 to fix the two together. When the rotating member 60 receives the power transmitted by the driving part 40 and rotates, the rotating member 60 drives the insulating member 76 to move as a whole, so that the part of the insulating member 76 located at the lower end surface of the power supply member and the control unit 70 is pulled away from between the two, the power supply member and the control unit 70 are electrically connected, and the control unit 70 makes the light-emitting member 55 emit light.

[0213] A mounting groove or a mounting buckle or other components may be provided at the fourth end 14 to support the insulating member 76 .

[0214] In one embodiment, the insulating member 76 can also be manually pulled out from between the power supply unit and the lower end surface of the control unit 70 .

[0215] The purpose of providing the insulating member 76 in this embodiment is to prevent the power of the power supply member from being consumed when the developing cartridge 1 is not installed in the image forming apparatus.

[0216] Embodiment 12:

[0217] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment. The difference between this embodiment and the eighth embodiment lies in the different structure of the transmission assembly.

[0218] like Figure 46-Figure 49 As shown, in this embodiment, the transmission assembly only includes a driving part 40, a developing gear 41 and a powder feeding gear 42, and the meshing part 600 of the rotating member 60 directly meshes with the driving gear 401 to receive power and rotate, and after rotating, it disengages from the driving gear 401 and no longer rotates. This structure can simplify the structure of the first end 11, thereby reducing the cost of the developing box 1. Correspondingly, in this embodiment, the switch member 71 that contacts the rotating member 60 is also arranged adjacent to the driving part 40, and the connecting member 53 extends from the first end 11 to the second end 12 through the sixth end 16, and the connecting member 53 is covered by the cover plate 163.

[0219] In addition to the abutment protrusion 605, the rotating member 60 is also provided with a limited protrusion 606. The first protective cover 111 is correspondingly provided with a limited protrusion 1110. The limited protrusion 606 is in contact with the limited protrusion 1110. When the rotating member 60 is not rotating or after the rotation is completed, the limited protrusion 1110 prevents the rotating member 60 from shaking.

[0220] The powder filling port 122 is disposed at the first end 11 , and when viewed from the first direction, the powder filling port 122 does not overlap with the first protective cover 111 .

[0221] The developing box 1 includes a first forcing portion 1111 located at the first end 11 and a second forcing portion 1215 located at the second end 12. The first forcing portion 1111 and the second forcing portion 1215 are used to receive the forcing force applied by the drum assembly to ensure that the developing roller 131 and the photosensitive drum are in close contact. In this embodiment, the first forcing portion 1111 is preferably arranged at the rear end of the first protective cover 111, and the second forcing portion 1215 is arranged at the rear end of the second protective cover 121. In the first direction, the handle 141 is located between the first forcing portion 1111 and the second forcing portion 1215. In the first direction, the handle 141 is closer to the developing roller 131 than the first forcing portion 1111 and the second forcing portion 1215.

[0222] In this embodiment, in the second direction, the rear wall 140 of the box body 10 (i.e., the end wall of the fourth end 14) is closer to the rotation axis of the driving unit 40 than the first forced pushing portion 1111. In the second direction, there is a first distance L1 between the rotation axis of the driving unit 40 and the rear wall 140. The size of the first distance L1 is 40mm-55mm.
