[0237] Embodiment 1

[0238] like Figures 1 to 11 As shown, this embodiment discloses a developing box 1, which can be detachably combined with a drum assembly, and can be detachably installed together with the drum assembly into an image forming device having a detection member and an identification contact.

[0239] like Figures 1 to 3 As shown, the developing box 1 includes a box body 10, the box body 10 has a receiving cavity inside, the receiving cavity is used to receive the developer, the box body 10 has a first end 11 and a second end 12 in the first direction, a third end 13 and a fourth end 14 in the second direction, and a fifth end 15 and a sixth end 16 in the third direction. The first direction, the second direction, and the third direction intersect with each other, and are preferably orthogonal to each other.

[0240] As an embodiment of the first direction, the second direction, and the third direction, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0241] A developing roller 131, a powder feeding roller and a stirring frame are rotatably installed in the accommodating chamber of the box body 10. The developing roller 131, the powder feeding roller and the stirring frame rotate around the developing roller axis, the powder feeding roller axis and the stirring frame axis extending in the first direction respectively. In the front-to-back direction, the developing roller 131 is located at the third end 13 (i.e., the front end), and the fourth end 14 (i.e., the rear end) is provided with a handle 141 for the user to take.

[0242] like Figure 2 As shown, the first end 11 is provided with a driving part 21, and the driving part 21 receives external power to rotate. The rotation axis of the driving part 21 extends in a first direction. The driving part 21 includes a power receiving part 211 and a driving gear 212, which are coaxially formed as one body or separately combined. The power receiving part 211 is used to receive power provided by the image forming device. In the first direction, the driving gear 212 is further to the left than the power receiving part 211.

[0243] like Figure 4 As shown, the developing box 1 also includes a triggering portion 41 for contacting the detecting member and driving the detecting member to move to trigger the detecting member, a power supply component (electrode) for receiving electric energy provided by the image forming device and transmitting the electric energy to the developing roller 131 and / or the powder feeding roller, and an identification component for storing information related to the developing box 1 (model, capacity, life, etc.) and being contacted by an identification terminal in the image forming device to read the stored information.

[0244] The power supply assembly is disposed at the second end 12 of the box body 10 , and includes an electric receiving surface 61 for contacting with the power supply terminal to receive electric energy provided by the image forming device, and the electric receiving surface 61 is located at the second end 12 .

[0245] The identification component includes a storage medium and an electrical contact surface 51, which is electrically connected to the storage medium and arranged at the first end 11. The storage medium stores information about the developing box 1, and the electrical contact surface 51 is in direct contact with the identification terminal to transfer the information in the storage medium to the image forming device.

[0246] like Figure 2 As shown, a driving assembly is provided on the developing box 1, and the driving assembly is used to transmit power to the developing roller 131, the powder feeding roller, and the stirring frame, so that the developing roller 131, the powder feeding roller, and the stirring frame rotate. The driving assembly includes:

[0247] A developing gear 22 is coaxially fixedly mounted on the right end of the developing roller 131, a powder feeding gear 23 is coaxially fixedly mounted on the right end of the powder feeding roller, a stirring gear 24 is coaxially fixedly mounted on the right end of the stirring frame, and an idler gear 25 is rotatably mounted on the first end 11. The developing gear 22, the powder feeding gear 23 and the idler gear 25 are meshed with the driving gear 212 to receive power, and the stirring gear 24 is meshed with the idler gear 25 to receive power. This embodiment does not limit the number of idlers and the meshing relationship between the gears, and can be set according to actual needs.

[0248] like Figure 1-Figure 6 As shown, a transmission assembly is provided on the developing box 1, and the transmission assembly is used to transmit power to the trigger part 41, so that the trigger part 41 can move between the detection position and the non-detection position. The transmission assembly is connected to the driving assembly to obtain power, and transmits the power to the detected part 4 to make it move.

[0249] The transmission assembly includes a plurality of rotating members, and the rotation axes of at least some of the rotating members intersect with the first direction and the second direction, preferably the rotation axes of at least three rotating members intersect with the first direction, and preferably the rotation axes of 8 to 16 rotating members intersect with the first direction. The transmission assembly includes: a first rotating member 31, a second rotating member 32, a third rotating member 33, a fourth rotating member 34, and a transmission rotating member 35. In this embodiment, the first rotating member 31, the second rotating member 32, the third rotating member 33, the fourth rotating member 34, and the transmission rotating member 35 are respectively implemented as a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear, and a fifth transmission gear.

[0250] like Figure 2 and Figure 7 As shown, the first rotating member 31 (first transmission gear) is rotatably mounted on the first end 11 and the rotation axis is parallel to the first direction. The first rotating member 31 meshes with the idler 25 to receive power. The first rotating member 31 includes a first tooth portion 311 and a second tooth portion 312 coaxially arranged. The first tooth portion 311 is further to the right than the second tooth portion 312, and the first tooth portion 311 meshes with the idler 25. In this embodiment, the first tooth portion 311 is a helical tooth or a straight tooth, and the second tooth portion 312 is a bevel tooth. A missing tooth portion 3111 is also provided on the first tooth portion 311 of the first rotating member 31. When the missing tooth portion 3111 is opposite to the idler 25, the first rotating member 31 is disconnected from the idler, that is, the first rotating member 31 no longer rotates.

[0251] like Figure 1 and Figure 2As shown, the second rotating member 32 (second transmission gear) is rotatably mounted on the fifth end 15 (i.e., the upper end), and the rotation axis of the second rotating member 32 preferably extends in the third direction (may be parallel to the third direction or slightly intersect with it, i.e., intersect with the first direction), and the second rotating member 32 includes a third tooth portion 321 and a fourth tooth portion 322 arranged coaxially, and the third tooth portion 321 meshes with the second tooth portion 312. In this embodiment, the third tooth portion 321 is a bevel tooth, and the fourth tooth portion 322 is a straight tooth or a helical tooth. The third tooth portion 321 meshes with the second tooth portion 312 so that the second rotating member 32 receives the power transmitted by the first rotating member 31 and rotates. That is, the first rotating member 31 and the second rotating member 32 transmit power by meshing, and the meshing method can be ordinary gear meshing, cylindrical pin (pin wheel) meshing, or abutment transmission between protrusions.

[0252] like Figure 1 As shown, the third rotating member 33 (third transmission gear) is rotatably mounted on the fifth end 15, and the rotation axis of the third rotating member 33 extends in the third direction (may be parallel to or slightly intersect with the third direction, that is, intersect with the first direction), and the third rotating member 33 is provided with a fifth tooth portion 331. In this embodiment, the fifth tooth portion 331 is a straight tooth or a helical tooth. The number of the third rotating members 33 is multiple, and the structures of the multiple third rotating members 33 are the same, so as to simplify the component structure on the developing box 1 and the composition of the developing box 1. In this embodiment, the number of the third rotating members 33 is preferably six, and the third rotating members 33 are arranged on the fifth end 15 of the box body 10 from right to left in sequence. The third rotating member 33 on the far right can be regarded as the initial third rotating member 330, and the third rotating member 33 on the far left can be regarded as the final third rotating member 33n. The final third rotating member 33n is farther away from the first end 11 than the initial third rotating member 330. The fifth tooth portion 331 of the initial third rotating member 33n is engaged with the fourth tooth portion 322 of the second rotating member 32 to receive power and rotate and transmit the power to the final third rotating member 33n in sequence. The number of the third rotating members 33 can be set arbitrarily, and different numbers of third rotating members 33 are selected according to different developing boxes 1.

[0253] like Figure 4 and Figure 5As shown, the fourth rotating member 34 (fourth transmission gear) is rotatably mounted on the fifth end 15, the rotation axis of the fourth rotating member 34 is parallel to the third direction (it may also slightly intersect with the third direction, i.e., intersect with the first direction), the fourth rotating member 34 includes a sixth tooth portion 341 (small tooth portion) and a seventh tooth portion 342 (large tooth portion) coaxially arranged, the sixth tooth portion 341 is located on the upper side of the seventh tooth portion 342 in the third direction, and the sixth tooth portion 341 and the seventh tooth portion 342 in this embodiment are straight teeth or helical teeth. The sixth tooth portion 341 meshes with the fifth tooth portion 331 so that the fourth rotating member 34 receives the power transmitted by the third rotating member 33 and rotates, the diameter of the sixth tooth portion 341 is smaller than the diameter of the seventh tooth portion 342 and the fifth tooth portion 331, so that the rotation speed of the fourth rotating member 34 is greater than that of the third rotating member 33. In other embodiments, different numbers of fourth rotating members 34 may be provided to further increase the rotational speed, or the seventh tooth portion 342 may be meshed with the fifth tooth portion 331 so that the speed of the fourth rotating member 34 is less than that of the third rotating member 33, so as to meet the requirements of different models of developing boxes 1.

[0254] The transmission rotating member 35 (fifth transmission gear) is rotatably mounted on the fifth end, the rotation axis of the transmission rotating member 35 is parallel to the third direction (it may also slightly intersect with the third direction, i.e., intersect with the first direction), the transmission rotating member 35 includes a transmission tooth portion 351, the transmission tooth portion 351 is a straight tooth or a helical tooth, the transmission tooth portion 351 is meshed with the seventh tooth portion 342 so that the transmission rotating member 35 receives the power transmitted by the fourth rotating member 34 and rotates, and a transmission protrusion 352 is provided on the upper end surface of the transmission rotating member 35, and the transmission protrusion 352 extends upward in the third direction. That is, in this embodiment, there are 9 rotating members whose rotation axis intersects with the first direction. In some embodiments, at least part of the second rotating member 32, the third rotating member 33, the fourth rotating member 34 and the transmission rotating member 35 is located at the fourth end 14 and the rotation axis extends in the second direction.

[0255] like Figure 5 As shown, the developing box 1 also includes a detected member 4, and a first pivot shaft 151 is further provided on the fifth end 15. The detected member 4 is rotatably mounted on the first pivot shaft 151 and can pivot around the first pivot shaft 151. The extension direction of the first pivot shaft 151 intersects with the first direction, and is preferably parallel to the third direction, that is, the rotation axis of the detected member 4 is parallel to the third direction. In other embodiments, the first pivot shaft 151 can also be fixedly set on the detected member 4, and a hole for inserting the first pivot shaft 151 is provided on the fifth end 15, which can also achieve the effect of enabling the detected member 4 to be rotatably mounted on the fifth end 15.

[0256] like Figures 4 to 6As shown, the detected member 4 includes a driven member 42 located on the right side of the first pivot axis 151, and a triggering portion 41 located on the left side of the first pivot axis 151, the triggering portion 41 and the driven member 42 are formed in one piece or in a split combination, and the triggering portion 41 is located at the second end 12 and exposed from the opening of the second protective cover 121 to facilitate contact with the detection member. The lower end surface of the driven member 42 is provided with a first driven portion 421, a second driven portion 422, a third driven portion 423, and a fourth driven portion 424, and the first driven portion 421, the second driven portion 422, the third driven portion 423, and the fourth driven portion 424 are all formed by protruding downward in the third direction. The second driven portion 422, the third driven portion 423, and the fourth driven portion 424 can all be driven by the transmission protrusion 352 to drive the detected member 4 to pivot from the non-detection position to the detection position around the first pivot axis 151, that is, the transmission rotating member 35 drives the detected member 4 to move as a transmission member. The first driven part 421 is in the shape of an arc track composed of two arc-shaped ribs spaced apart in the radial direction and protruding downward. The fourth driven part 424 is connected to the upstream end of the first driven part 421 in the rotation direction of the transmission rotating member 35, and the transmission rotating member 35 rotates counterclockwise. In the process of moving from the non-detection position to the detection position, the trigger part 41 contacts the detection member and drives the detection member to move and generate an electrical signal.

[0257] A reset elastic member 36 is also installed on the fifth end 15, one end of the reset elastic member 36 is fixedly connected to the first connecting portion 152 fixed on the fifth end 15 and protruding upward, and the other end is fixedly connected to the second connecting portion 43 fixedly arranged on the upper end of the driven member 42 of the detected member 4 and protruding upward. The reset elastic member 36 is used to maintain the detected member 4 / trigger portion 41 in the non-detection position, and the reset elastic member 36 can be an elastic member such as a tension spring.

[0258] The specific detection process is as follows:

[0259] The power receiving part 211 receives power and drives the transmission assembly through the driving gear 212, and the transmission assembly causes the transmission rotating member 35 to rotate, and the transmission protrusion 352 rotates along with the transmission rotating member 35 in a counterclockwise direction (from a top-down perspective) to make a circular motion.

[0260] like Figure 7 and Figure 8 As shown, when the transmission protrusion 352 is in the initial position, the transmission protrusion 352 is at the upstream end of the first driven part 421 in the rotation direction of the transmission rotating member 35. With the circular motion of the transmission protrusion 352, the transmission protrusion 352 moves in the first driven part 421, so that the detected member 4 / trigger part 41 is maintained in the detection position, so that the detection member maintains the triggered state and the maintenance time is T1, and the central angle of the trigger part 41 on the circle formed by the rotation trajectory of the transmission protrusion 352 is A1.

[0261] like Fig. 9 As shown, with the circular motion of the transmission protrusion 352 , after the transmission protrusion 352 is out of contact with the first driven portion 421 , the detected member 4 / trigger portion 41 pivots clockwise to the non-detection position under the action of the reset elastic member 36 .

[0262] Then, the transmission protrusion 352 contacts the second driven part 422, so that the second driven part 422 receives the power of the transmission protrusion 352 and drives the detected part 4 to rotate counterclockwise, thereby causing the trigger part 41 to move to the detection position, triggering the detection part again and maintaining the trigger state for a time of T2. The central angle of the second driven part 422 on the circle formed by the rotation trajectory of the transmission protrusion 352 is A2.

[0263] Then, the transmission protrusion 352 is out of contact with the second driven portion 422 , and under the action of the reset elastic member 36 , the detected member 4 / trigger portion 41 pivots clockwise to the non-detection position.

[0264] Then, the transmission protrusion 352 contacts the third driven part 423, so that the third driven part 423 receives the power of the transmission protrusion 352 and drives the detected part 4 to swing counterclockwise, thereby causing the trigger part 41 to move to the detection position, triggering the detection part again and maintaining the trigger state for a time of T3. The central angle of the third driven part 423 on the circle formed by the rotation trajectory of the transmission protrusion 352 is A3.

[0265] Then, the transmission protrusion 352 is out of contact with the third driven portion 423 , and under the action of the reset elastic member 36 , the detected member 4 / trigger portion 41 pivots clockwise to the non-detection position.

[0266] like Figure 8 and Fig.10As shown, then, the driving protrusion 352 contacts the fourth driven part 424, causing the fourth driven part 424 to receive the power of the driving protrusion 352 and drive the detected part 4 to swing counterclockwise, so that the triggering part 41 moves to the detection position, triggering the detector again, and the maintenance time of the triggering state is T4. The central angle subtended by the fourth driven part 424 on the circle formed by the rotation trajectory of the driving protrusion 352 is A4. The angle of A4 < the angles of A2 and A3 < the angle of A1. And since the stroke of the detected part 4 / triggering part 41 from the non-detection position to the detection position is the same each time, and the rotation speed of the driving protrusion 352 is constant, then the smaller the central angle subtended, the faster the moving speed of the detected part 4 / triggering part 41. Thus, when the driving protrusion 352 passes through the fourth driven part 424, the speed at which the triggering part 41 moves from the non-detection position to the detection position is the second speed V2. When the driving protrusion 352 passes through the second driven part 422 and the third driven part 423, the speed at which the triggering part 41 moves from the non-detection position to the detection position is the first speed V1, and the second speed V2 is greater than the first speed V1. And because the angle of A1 is the largest, when the driving protrusion 352 contacts the first driven part 421, the time T1 for which the triggering part 41 remains in the detection position > T2, T3, T4.

[0267] As Fig.11 shown, then the first rotating part 31 rotates to the end position. At this time, the toothless part 3111 faces the idle gear 25, so that the first rotating part 31 can no longer receive power. Therefore, the transmission assembly cannot receive power, causing the second rotating part 32, the third rotating part 33, the fourth rotating part 34, and the driving rotating part 35 to stop rotating, thus completing the detection process. In some embodiments, the toothless part can be provided on any one of the rotating parts in the transmission assembly or on the idle gear 25.

[0268] In this embodiment, the transmission assembly transmits the power from the first end 11 to the second end 12 through multiple rotating parts (in the manner of multiple gears meshing), causing the triggering part 41 to trigger the detector to complete the detection. Moreover, by varying the time, speed, and number of times the triggering part 41 remains in the detection position, through the permutation and combination of the above information, different models of the developing cartridge 1 can be corresponded to, so that the detector in the image forming apparatus can detect information such as whether the developing cartridge 1 is installed, new or old, model, life, capacity, etc. according to the above information.

[0269] Those skilled in the art can change the number of times the trigger part 41 enters the detection position by increasing or decreasing the first driven part 421, the second driven part 422, the third driven part 423, and the fourth driven part 424, and can change the speed and duration of the trigger part 41 entering the detection position by changing the central angle of the circle subtended by the first driven part 421, the second driven part 422, the third driven part 423, and the fourth driven part 424.

[0270] In some embodiments, there is no need to set up a separate driving unit, and the developing gear 22 serves as a driving unit to receive external power. Specifically, the developing gear 22 meshes with the gear on the drum assembly to receive power and transmit the power to the remaining gears. Specifically, when the developing box 1 is installed on the drum assembly, the developing gear 22 meshes with the photosensitive drum gear on the drum assembly, so that the photosensitive drum rotates and the developing gear 22 is driven to rotate through the photosensitive drum gear, so that the power is transmitted to the developing box 1. The powder feeding gear 23 and the stirring gear 24 are directly or indirectly meshed with the developing gear 22 to realize the transmission of power to each component on the developing box 1. This embodiment can make it unnecessary to set up a power output member specifically for the developing box 1 in the image forming device, which can reduce costs.

[0271] In other implementations, the power can be transmitted from the first end 11 to the second end 12 by using a plate that swings or moves in the first direction as a transmission member to move the detected member 4. The plate and the detected member 4 can also be integrally formed.

[0272] Embodiment 2:

[0273] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment.

[0274] like Fig.12 As shown, the difference between this embodiment and embodiment one is that the second tooth portion 312a is configured as a plurality of cylindrical pin teeth, and the plurality of cylindrical pin teeth are arranged in sequence in the rotation direction of the first rotating member 31a, and the cylindrical pin teeth extend in the radial direction of the first rotating member 31a in the direction away from the rotation axis of the first rotating member 31a.

[0275] The third tooth portion 321a is matched to be arranged in a plurality of cylindrical pin teeth, and the plurality of cylindrical pin teeth are arranged in sequence in the rotation direction of the second rotating member 32a, and the cylindrical pin teeth extend in the radial direction of the second rotating member 32a in a direction away from the rotation axis of the second rotating member 32a. The missing tooth portion is arranged on the third tooth portion 321a, and may also be arranged on the second tooth portion 312a.

[0276] The third tooth portion 321a is engaged with the second tooth portion 312a (cylindrical pin tooth engagement), so that the first rotating member 31a drives the second rotating member 32a to rotate. The fourth tooth portion 322a of the second rotating member 32a is engaged with the third rotating member 33a.

[0277] This embodiment also eliminates the fourth rotating member, and the number of the third rotating members 33a is eight. The eight third rotating members 33a are engaged in sequence, and the last third rotating member 33a (the farthest from the first rotating member 31a) is directly engaged with the transmission rotating member 35a to transmit power to the transmission rotating member 35a.

[0278] In this embodiment, the trigger portion 41a is directly disposed on the transmission rotating member 35a, that is, the transmission rotating member 35a can be regarded as a detected member. Four trigger portions 41a are arranged at intervals along the circumferential direction on the transmission rotating member 35a. The trigger portion 41a is a protrusion structure, and the trigger portion 41a is formed by extending along the radial direction of the transmission rotating member 35a in the direction away from the rotation axis of the transmission rotating member 35a. The number of trigger portions 41a is set according to actual needs, and the central angles corresponding to the multiple trigger portions 41a can be the same or different, so that the time for the trigger portion 41a to maintain the detection position is different, so as to adapt to the identification of different types of developer boxes 1.

[0279] Embodiment three:

[0280] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the second embodiment.

[0281] like Fig.13 and Fig.14 As shown, the difference between this embodiment and the second embodiment is that: only one triggering part 41c is provided on the transmission rotating member 35c (the detected member); a driving protrusion is provided on the first rotating member 31c, and the driving protrusion extends in the radial direction of the first rotating member 31c in the direction away from the axis of the first rotating member 31c, and the driving protrusion includes a first driving protrusion 312c, a second driving protrusion 313c, and a third driving protrusion 314c arranged in sequence with intervals along the rotation direction of the first rotating member 31c. The first rotating member 31c only includes a first tooth portion 311c for receiving the power of the driving assembly, and the second tooth portion is cancelled, and the third tooth portion is cancelled on the second rotating member 32c, that is, the two are not engaged by gears. The second rotating member 32c is provided with a driven portion 321c (i.e., a protrusion structure) extending along the radial direction of the second rotating member 32c toward a direction away from the rotation axis of the second rotating member 32c, and the driven portion 321c is located on the moving track of the first driving protrusion 312c, the second driving protrusion 313c, and the third driving protrusion 314c. In this embodiment, there are 10 rotating members whose rotation axis intersects the first direction.

[0282] The length (arc length) of the first driving protrusion 312c in the circumferential direction (ie, the rotation direction) of the first rotating member 31c is greater than that of the second driving protrusion 313c and the third driving protrusion 314c.

[0283] A reset elastic member (not shown) is provided between the transmission rotating member 35 c and the box body 10 . In this embodiment, the reset elastic member is a torsion spring, one end of which abuts against the transmission rotating member 35 c , and the other end abuts against the box body 10 .

[0284] When the first driving protrusion 312c, the second driving protrusion 313c and the third driving protrusion 314c pass through the driven part 321c in sequence, a force is applied to the driven part 321c, so that the second rotating member 32c rotates, and the second rotating member 32c transmits power to the fifth transmission gear 35c through the third rotating member 33c, so that the trigger part 41c rotates from the non-detection position to the detection position along with the fifth transmission gear 35c.

[0285] When the intervals among the first driving protrusion 312c, the second driving protrusion 313c and the third driving protrusion 314c move to the driven part 321c, under the action of the reset elastic member, the transmission rotating member 35c rotates clockwise and reverses a certain angle so that the trigger part 41c moves from the detection position to the non-detection position, thereby causing the third rotating member 33c and the second rotating member 32c to also reverse a certain angle, so that the driven part 321c returns to a position where it can be touched by the first driving protrusion 312c, the second driving protrusion 313c and the third driving protrusion 314c for the next touch.

[0286] Embodiment 4:

[0287] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment.

[0288] like Figures 15 to 23 As shown, the difference between this embodiment and the first embodiment is that the fourth rotating member is eliminated, and the structures of the transmission rotating member and the detected member are different.

[0289] like Fig.17As shown, in this embodiment, the box body 10 is provided with a first support column 101, a second support column 102, a third support column 103, a fourth support column 104 and a fifth support column 105. The first support column 101 and the second support column 102 are located at the first end 11 and extend along the first direction, and the third support column 103, the fourth support column 105 and the fifth support column 105 extend along the third direction. The third support column 103 is arranged near the first end 11, and the fifth support column 105 is arranged near the second end 12. In this embodiment, the fourth support column 104 is provided in plurality, and the plurality of fourth support columns 104 are arranged in the first direction. The box body 10 is provided with a mounting groove that is recessed along the third direction and extends along the first direction, and the plurality of fourth support columns 104 are located in the mounting groove. In this embodiment, the number of the fourth support columns 104 is preferably 13, and the number of the fourth support columns 104 can be set according to actual needs in other embodiments. In this embodiment, the above-mentioned support columns are preferably cylindrical.

[0290] like Figures 15 to 19 As shown, the driving part 21 is located at the first end 11, and the driving part 21 is rotatably supported by the first support column 101, and the rotation axis of the driving part 21 extends in the first direction. The first rotating member 31d is rotatably supported by the second support column 102, and the rotation axis of the first rotating member 31d extends in the first direction. The second rotating member 32d is rotatably supported by the third support column 103, and the rotation axis of the second rotating member 32d extends in the third direction. The third rotating member 33d is rotatably supported by the fourth support column 104, and multiple third rotating members 33d are provided and arranged in the first direction. The multiple third rotating members 33d are meshed with each other, and the number of the third rotating members 33d matches the number of the fourth support column 104. In this embodiment, 13 third rotating members 33d are preferably provided. Along the first direction, the first end 11 points to the second end 12 as the indication direction, the third rotating member 33d closest to the first end 11 is the initial third rotating member 33d1, and the third rotating member 33d closest to the second end 12 is the final third rotating member 33dn. The initial third rotating member 33d1 is meshed with the second rotating member 32d to receive power and rotate and drive each third rotating member 33d to rotate, that is, the fourth tooth portion 322d of the second rotating member 32d is meshed with the fifth tooth portion of the initial third rotating member 33d1, and the diameter of the fifth tooth portion is greater than the diameter of the fourth tooth portion. In this embodiment, the diameter of the third tooth portion 321d of the second rotating member 32d is greater than the diameter of the fourth tooth portion 322d, and in the third direction, the third tooth portion 321d is at least partially located between the fourth tooth portion 322d and the outer surface of the fifth end 15.

[0291] like Fig.16 and Fig. 20As shown, the developing box 1 also includes a transmission rotating member 35d, which is arranged near the second end 12, and the transmission rotating member 35d is rotatably supported by the fifth support column 105. The transmission rotating member 35d includes a transmission tooth portion 351d and a transmission protrusion 352d, and the transmission tooth portion 351d is meshed with the third rotating member 33dn to receive power to rotate the transmission rotating member 35d. The transmission protrusion 351d is arranged on the lower surface of the transmission rotating member 35d and protrudes downward in the third direction. The transmission protrusion 351d is arranged near the circumferential edge of the transmission rotating member 35d, and the transmission protrusion 352d has an abutment surface, which is an inclined surface, a curved surface or a straight surface, and the abutment surface is used to abut with the detected member 4d to drive the detected member 4d. In this embodiment, the extension direction of the abutment surface preferably intersects with the third direction. That is, in this embodiment, there are 15 rotating members whose rotation axis intersects with the first direction.

[0292] like Figure 20 to Figure 22 As shown, the detected member 4d is located at the second end 12 and is used to trigger the detection member. The detected member 4d includes a triggering portion 41d, a driven member 42d and a supported portion 43d. In the first direction, the supported portion 43d is located between the driven member 42d and the triggering portion 41d. The driven member 42d is used to receive the power that causes the detected member 4d to move. In this embodiment, the driven member 42d is preferably an inclined surface (the inclined surface includes a curved surface and a straight surface). The driven member 42d is abutted by the transmission protrusion 352d of the transmission rotating member 35d to cause the detected member 4d to swing. The extension direction of the swing axis of the detected member 4d intersects with the first direction, and the swing axis preferably extends in the second direction. The supported portion 43d is the rotation center of the swing of the detected member 4d, and the supported portion 43d is cylindrical extending in the second direction. The second protective cover 121 is provided with a first clamping portion 1212, and the first clamping portion 1212 is semicircular or full-circular. In this embodiment, it is preferably semicircular. The supported portion 43d is a rotatable support for the first clamping portion 1212, so that the detected member 4d can be movably mounted on the second protective cover 121. In some embodiments, the detected member 4d is movably supported by the box body 10. The triggering portion 41d is used to directly contact the detection member, and the detection member is triggered during the upward swing of the triggering portion 41d.

[0293] like Fig. 22 As shown, a placement portion 1213 is provided on the second protective cover 121, and a reset elastic member 36d is placed on the placement portion 1213. The reset elastic member 36d is an elastic member such as a sponge or a compression spring. In this embodiment, it is preferably a sponge. When the detected member 4d swings, the reset elastic member 36d is compressed and accumulates elastic potential energy. After the driven member 42d is separated from the abutment of the transmission protrusion 352d, the detected member 4d swings in the opposite direction under the elastic action of the reset elastic member 36d to reset.

[0294] When the detected member 4d needs to trigger the detection member multiple times, the transmission protrusion 352d on the transmission rotating member 35d can be made to abut against the detected member 4d multiple times or multiple transmission protrusions 352d can be provided on the transmission rotating member 35d.

[0295] In order to prevent the detected part from swinging after the detection is completed, the transmission tooth portion 351d of the transmission rotating part 35d can be set as a missing tooth portion to disconnect the engagement with the third rotating part 33d, or the third rotating part 33d or the second rotating part 32d or the first rotating part 31d can be set with a missing tooth portion to disconnect the transmission.

[0296] In this embodiment, the detected member 4d is made of a conductive material such as resin. The detected member 4d can be used as an electrode to receive the voltage output by the image forming device. A conductive member is provided between the detected member 4d and the developing roller 131. The conductive member electrically connects the detected member 4d and the developing roller 131 so that the detected member 4d transfers the voltage to the developing roller 131. In this embodiment, the conductive member is preferably a steel sheet.

[0297] like Fig.21 As shown, a locking member 1211 is further provided on the second protective cover 121 , and the locking member 1211 is used to prevent the developing box 1 from being separated.

[0298] like Fig.21 As shown, the second end 12 is also provided with a powder filling port and a sealing cover 123 overlapping with the powder filling port in the first direction. In the second direction, the powder filling port is located behind the detection member 4d. The developer is poured into the box body 10 through the powder filling port. The sealing cover 123 is used to seal the powder filling port to prevent leakage of the developer.

[0299] like Fig.16 As shown, in this embodiment, a cover 150 is detachably fixedly mounted on the fifth end 15. The cover 150 is mounted on the box body 10 by snapping and screw fixing. The cover 150 at least covers part of the transmission assembly, and plays a role in preventing and protecting the transmission assembly from falling off. In some embodiments, a support column for rotatably supporting a rotating member whose rotation axis extends in the third direction can be disposed on the cover 150, so that the cover 150 at least rotatably supports part of the transmission assembly.

[0300] Embodiment five:

[0301] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment.

[0302] like Figures 23 to 30 As shown, the difference between this embodiment and the first embodiment lies in the different structures of the detected parts.

[0303] like Figures 23 to 30As shown, in this embodiment, the missing tooth portion 343e is arranged on the sixth tooth portion 341e of the fourth rotating member 34e. The box body 10 is provided with a first pivot shaft 152e and a second pivot shaft 153e extending upward in the third direction. The detected member includes a first detected member 41e and a second detected member 42e. The first detected member 41e and the second detected member 42e are respectively rotatably mounted on the first pivot shaft 152e and the second pivot shaft 153e on the fifth end 15 around a rotation axis parallel to the third direction. The first detected member 41e includes a first driven member 412e and a first triggering portion 411e. The second detected member 42e includes a second driven member 422e and a second triggering portion 421e. The first driven member 412e is located on the right side of the first pivot shaft 152e. The first triggering portion 411e is located on the right side of the first pivot shaft 152e. 411e is located on the left side of the first pivot axis 152e, the second driven part 422e is located on the right side of the second pivot axis 153e, the second triggering part 421e is located on the left side of the second pivot axis 153e, the first triggering part 411e and the second triggering part 421e are used to trigger the detection part, the first triggering part 411e and the second triggering part 421e extend to the left beyond the fifth end 15, that is, the first triggering part 411e and the second triggering part 421e are located at the second end 12, the first driven part 4121e and the fourth driven part 4122e are arranged on the first driven part 412e, and the second driven part 4221e and the third driven part 4222e are arranged on the second driven part 422e.

[0304] The first driven portion 4121e, the second driven portion 4221e, the third driven portion 4222e, and the fourth driven portion 4122e are the same as those described in the first embodiment, and the only difference is that they are respectively arranged on the first detected member 41e and the second detected member 42e.

[0305] like Figure 23 to Figure 25As shown, a first abutting portion 413e is fixedly provided on the first detected member 41e, a second abutting portion 151e is fixedly provided on the fifth end 15 of the box body 101, and a first reset elastic member 43e is installed between the first abutting portion 413e and the second abutting portion 151e. In this embodiment, the first reset elastic member 43e is a torsion spring, and the first reset elastic member 43e is sleeved on the first pivot shaft 152e. One end of the first reset elastic member 43e abuts on the first abutting portion 413e, and the other end abuts on the second abutting portion 151e. In this embodiment, the second reset elastic member 44e is a compression spring, one end of the second reset elastic member 44e abuts on the third abutting portion 423e fixed on the second detected member 42e, and the other end of the second reset elastic member 44e abuts on the fourth abutting portion 154e fixed on the fifth end 15 of the box body 101, and the third abutting portion 423e and the fourth abutting portion 154e are arranged opposite to each other. The first restoring elastic member 43e is used to keep the first detected member 41e at the non-detecting position, and the second restoring elastic member 44e is used to keep the second detected member 42e at the non-detecting position.

[0306] The working process is as follows:

[0307] like Fig.26 As shown, the fourth rotating member 34e starts to rotate. In the initial state, the sixth tooth portion 341e of the fourth rotating member 34e is in meshing state with the fifth tooth portion of the third rotating member 33e. When the third rotating member 33e receives the power transmitted by the driving part 21 and rotates, the third rotating member 33e drives the fourth rotating member 34e to rotate counterclockwise (viewed from top to bottom), and the fourth rotating member 34e drives the transmission rotating member 35e to rotate clockwise through the meshing of the seventh tooth portion 342e with the transmission tooth portion.

[0308] like Figures 27 to 30 As shown, in the initial state, the transmission protrusion 352e is located in the first driven part 4121e and maintains abutment with the first driven part 4121e, that is, the first detected member 41e is in the detection position in the initial state. As the transmission protrusion 352e rotates, the transmission protrusion 352e leaves the first driven part 4121e and loses contact with the first driven part 4121e. Under the action of the first reset elastic member 43e, the first detected member 41e swings clockwise from the detection position to a certain angle and rotates to the non-detection position.

[0309] Then the transmission protrusion 352e contacts the second driven part 4221e and the third driven part 4222e on the second detected part 42e in turn, so that the second detected part 42e rotates counterclockwise from the non-detection position to the detection position at a certain angle twice at the first speed V1, so that the second triggering part 421e touches and triggers the detection part twice at the first speed V1.

[0310] like Fig.30 As shown, the transmission protrusion 352e then contacts the fourth driven portion 4122e on the first detected member 41e, so that the first detected member 41e rotates counterclockwise at a certain angle from the non-detection position to the detection position at a second speed V2, thereby causing the second triggering portion 421e on the second detected member 42e to touch and trigger the detection member at the second speed V2, and the second speed V2 is greater than the first speed V1, thereby enabling the image forming device to determine the information of the developing box 1 according to the different touching speeds.

[0311] When the fourth rotating member 34e stops transmitting to the third rotating member 33e, the first detected member 41e and the second detected member 42e also stop moving, and the detection process is completed.

[0312] Embodiment six:

[0313] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment.

[0314] like Figure 31 to Figure 44 As shown, the difference between this embodiment and the first embodiment is that the idler wheel in this embodiment includes a first idler wheel 25f and a second idler wheel 26f.

A first support shaft 241f is coaxially fixedly arranged on the stirring gear 24f, and the sixth rotating member 36f is supported by the first support shaft 241f and can rotate relative to the first support shaft 241f, that is, the rotation of the stirring gear 24f will not drive the sixth rotating member 36f to rotate, and the rotation axis of the sixth rotating member 36f extends in the first direction, and the sixth rotating member 36f includes a ninth tooth portion 361f and a tenth tooth portion 362f coaxially fixedly arranged. In the first direction, the ninth tooth portion 361f is located on the left side of the tenth tooth portion 362f, and the radius of the ninth tooth portion 361f is greater than the radius of the tenth tooth portion 362f. The ninth tooth portion 361f is meshed with the second idler gear 26f, and the tenth tooth portion 362f is meshed with the first tooth portion of the first rotating member 31f, so that the rotation direction of the stirring gear 24f is opposite to that of the sixth rotating member 36f, but since the sixth rotating member 36f can rotate relative to the first support shaft 241f, the rotation between the sixth rotating member 36f and the stirring gear 24f will not affect each other.

[0316] like Fig.33 and Fig.34As shown, the second end 12 is fixedly mounted with a second protective cover 121f, and the second protective cover 121f is provided with a first track 1211f and a second track 1212f, the first track 1211f and the second track 1212f extend in the second direction, the first detected member 41f and the second detected member 42f are respectively mounted in the first track 1211f and the second track 1212f, the first detected member 41f is supported by the first track 1211f and can slide linearly relative to the box body 10 along the first track 1211f in the second direction, and the second detected member 42f is supported by the second track 1212f and can slide linearly relative to the box body 10 along the second track 1212f in the second direction.

To facilitate the installation of the first detected component 41f into the first rail 1211f, the front ends of the first rail 1211f, the first groove 12112f and the second groove 12111f are all open, so that the first detected component 41f can be installed backwards into the first rail 1211f from the front ends of the first rail 1211f, the first groove 12112f and the second groove 12111f. The third connecting part 414f is fixedly arranged on the first sliding part 413f, and the fourth connecting part 12113f is fixedly arranged on the left wall of the first track 1211f. The third connecting part 414f and the fourth connecting part 12113f are both cylindrical, and the first resetting elastic member 45f is installed between the third connecting part 414f and the fourth connecting part 12113f. In this embodiment, the first resetting elastic member 45f is a tension spring, and the front end of the first resetting elastic member 45f is fixedly connected to the third connecting part 414f, and the rear end of the first resetting elastic member 45f is fixedly connected to the fourth connecting part 12113f. The first resetting elastic member 45f is used to keep the first detected member 41f in the non-detection position or have a tendency to move to the non-detection position.

[0319] like Figure 36 to Figure 39 As shown, the second detected member 42f includes a second sliding portion 423f and a second triggering portion 421f. The second sliding portion 423f is slidably installed in the second track 1212f, and the second triggering portion 421f extends to the left from the left end of the second sliding portion 423f and extends out of the second track 1212f. A third groove 12122f for the second triggering portion 421f to extend out is provided on the left wall of the second track 1212f, and the third groove 12122f extends in the second direction. In order to facilitate the installation of the second detected member 42f in the second track 1212f, the front ends of the second track 1212f and the third groove 12122f are both open, so that the second detected member 42f can be installed in the second track 1212f from the second track 1212f and the front end of the third groove 12122f backward. A first elastic member 46f is provided between the rear end of the second detected member 42f and the rear wall of the second track 1212f. In this embodiment, the first elastic member 46f is a compression spring. The front end of the first elastic member 46f abuts against the rear end of the second sliding portion 423f, and the rear end of the first elastic member 46f abuts against the rear wall of the second track 1212f. The first elastic member 46f is used to keep the second detected member 42f in the detection position or have a tendency to move to the detection position. The right end of the second sliding portion 423f is also provided with a first abutting portion 422f, and the first abutting portion 422f extends to the right from the right end of the second sliding portion 423f. A first hole 12121f is provided on the right wall of the second track 1212f.

The touch piece 43f includes a pivot portion, a first arm 431f, and a second arm 432f. The pivot portion is rotatably installed on the first pivot shaft 1213f, and the pivot portion can be set to a disc shape or a square shape. In this embodiment, the pivot portion is roughly square, and the first arm 431f is formed by extending from the pivot portion to the left, and the second arm 432f is formed by extending from the pivot portion to the right. The first arm 431f is located on the left side of the first pivot shaft 1213f, and the second arm 432f is located on the right side of the first pivot shaft 1213f. The trigger member 43f can move between a trigger position and a non-trigger position. When the trigger member 43f is in the trigger position, the second detected member 42f is not limited by the trigger member 43f in the direction of forward movement, so that the second detected member 42f can move forward to the detection position under the elastic force of the first elastic member 46f. When the trigger member 43f is in the non-trigger position, the first arm 431f passes through the first hole 12121f and extends into the second track 1212f to abut against the front end of the first abutment portion 422f. At the same time, the first arm 431f can also abut against the front wall of the first hole 12121f, so that the second detected member 42f is limited in the non-detection position by the first arm 431f. At the same time, the first arm 431f is limited by the first hole 12121f and cannot swing forward, thereby ensuring that the second detected member 42f can be maintained in the non-detection position, and the first elastic member 46f is in a state of generating elastic deformation and accumulating elastic potential energy.

[0321] like Fig.37 As shown, the first pivot shaft 1213f is also sleeved with a second elastic member 44f, which is a torsion spring, the second protective cover 121f is fixedly provided with a second abutting portion 1214f, the triggering member 43f is fixedly provided with a third abutting portion 433f, one end of the second elastic member 44f abuts against the second abutting portion 1214f and the other end abuts against the third abutting portion 433f. The second elastic member 44f is used to keep the triggering member 43f in a non-touch position or have a tendency to move toward the non-touch position.

[0322] like Fig.34 and Fig.35As shown, in this embodiment, the transmission rotating member 35f is fixedly provided with a first transmission protrusion 351f, a second transmission protrusion 352f, a third transmission protrusion 353f, and a fourth transmission protrusion 354f that move together with the transmission rotating member 35f. The distance between the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f and the fifth end 15 in the third direction is a first distance, and the distance between the fourth transmission protrusion 354f and the fifth end 15 in the third direction is a second distance, and the first distance is greater than the second distance, that is, the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are located above the fourth transmission protrusion 354f, so that the first driven part 412f is located on the moving path of the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f, and the second arm 432f of the trigger member 43f is located on the moving path of the fourth transmission protrusion 354f. The first transmission protrusion 351f, the second transmission protrusion 352f, the third transmission protrusion 353f, and the fourth transmission protrusion 354f are arranged in sequence from upstream to downstream in the rotation direction of the transmission rotating member 35f.

[0323] The first driven portion 412f of the first detected member 41f can be driven by sequentially contacting the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f, so that the first detected member 41f moves from the non-detection position to the detection position.

[0324] The second arm 432f of the triggering member 43f may be driven by contacting with the fourth transmission protrusion 354f, so that the triggering member 43f swings clockwise from the non-touch position to the touch position.

[0325] In this embodiment, the first rotating member 31f is not provided with a missing tooth portion, and the transmission tooth portion 355f of the transmission rotating member 35f is provided with a missing tooth portion 356f.

[0326] like Figures 40 to 44 As shown, the specific working process is as follows: the driving part 21 receives the power provided by the image forming device and rotates clockwise (viewed from right to left), and transmits the power to the transmission rotating member 35f through the driving component and the transmission component. In the initial state, the transmission tooth portion 355f is in a meshing state with the seventh tooth portion of the fourth rotating member 34, so that the transmission rotating member 35f rotates counterclockwise (viewed from top to bottom).

[0327] like Figure 40 to Figure 42As shown, the rotation of the transmission rotating member 35f causes the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f to contact the first driven part 412f in sequence, thereby driving the first detected member 41f to slide forward from the non-detection position to the detection position along the first track 1211f at a first speed, thereby triggering the detection member, causing the image forming device to generate an electrical signal, and at the same time causing the first reset elastic member 45f to be stretched and elastically deformed. As the transmission rotating member 35f rotates, when the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are out of contact with the first driven part 412f, under the action of the elastic force of the first reset elastic member 45f, the first detected member 41f moves backward from the detection position to the non-detection position along the first track 1211f. Thus, the first detected member 41f is touched and driven by the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f in sequence, so that the first detected member 41f moves forward from the non-detection position along the first track 1211f to the detection position three times at the first speed, so that the image forming device generates three electrical signals. And because the rotation speed of the transmission rotating member 35f remains unchanged, the linear speeds of the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are the same, so that the first detected member 41f is driven by the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f to move from the non-detection position to the detection position multiple times. The moving speed is the first speed. In other embodiments, the number of transmission protrusions can be increased or decreased to increase or decrease the number of times the first driven part 412f is driven, so that the image forming device can generate more or fewer electrical signals to distinguish different models and specifications of the developing box 1.

[0328] like Fig.43 and Fig.44As shown, in the initial state, the first elastic member 46f is in an elastic deformation state. When the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are all in contact with the first driven portion 412f, the fourth transmission protrusion 354f contacts the second arm 432f of the triggering member 43f and drives the triggering member 43f to swing clockwise from the non-touch position to the touch position by a certain angle, so that the first arm 431f of the triggering member 43f swings clockwise by a certain angle, so that the first arm 431f is disengaged from the first abutting portion 422f. The second detection member 42f is no longer in contact with the first elastic member 46f, thereby no longer having a limiting effect on the second detection member 42f. At this time, under the elastic force of the first elastic member 46f, the second detection member 42f moves forward from the non-detection position to the detection position along the second track 1212f at the second speed, thereby driving and triggering the detection member in the image forming device for the fourth time, and the second speed is greater than the first speed, so that the image forming device can generate different electrical signals according to different triggering speeds, thereby distinguishing information such as models and specifications of different developing cartridges 1. In other embodiments, first elastic members 46f of different specifications can be selected to increase or decrease the second speed.

[0329] In this embodiment, the first length of the first transmission protrusion 351f in the circumferential direction is greater than the second length of the second transmission protrusion 352f and the third transmission protrusion 353f in the circumferential direction, so that when the first transmission protrusion 351f contacts the first driven part 412f, the first detection member 41f is kept in the detection position for a longer time than when the second transmission protrusion 352f or the third transmission protrusion 353f contacts the first driven part 412f. In this way, the image forming device can distinguish different types and specifications of developing boxes 1 according to the time length that the first detection member 41f is kept in the detection position each time the detection member is triggered.

[0330] Embodiment seven:

[0331] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the sixth embodiment.

[0332] like Fig.45 and Fig.46As shown, the difference between this embodiment and embodiment six is ​​that the transmission assembly also includes a seventh rotating member 37g and an eighth rotating member 38g, the seventh rotating member 37g is a seventh transmission gear, the eighth rotating member 38g is an eighth transmission gear, the seventh rotating member 37g and the eighth rotating member 38g are coaxially arranged, the seventh rotating member 37g is located above the eighth rotating member 38g, the seventh rotating member 37g and the eighth rotating member 38g are rotatably arranged on the fifth end 15 of the box body 101 and the rotation axis is parallel to the third direction, the seventh rotating member 37g and the eighth rotating member 38g are located between the first third rotating member 331g and the second third rotating member 332g from right to left, the seventh rotating member 37g is meshed with the first third rotating member 331g, and the eighth rotating member 38g is meshed with the second third rotating member 332g, and the number of third transmission teeth in this embodiment is reduced by one third rotating member 33 replaced by the seventh rotating member 37g and the eighth rotating member 38g.

[0333] like Fig.45 and Fig.46 As shown, a first delay protrusion 371g is provided at the lower end of the seventh rotating member 37g, and a second delay protrusion 381g is provided at the upper end of the eighth rotating member 38g. In this embodiment, the number of the first delay protrusion 371g and the second delay protrusion 381g are both two. The first delay protrusion 371g is symmetrically arranged about the rotation axis of the seventh rotating member 37g, and the second delay protrusion 381g is symmetrically arranged about the rotation axis of the eighth rotating member 38g. In an initial state, the first delay protrusion 371g does not contact the second delay protrusion 381g. When the driving part 21 receives power and rotates, the first rotating member is driven to rotate by the driving assembly, and the first rotating member drives the second rotating member 32 to rotate. The second rotating member 32 drives the first third rotating member 331g to rotate, and the first third rotating member 331g drives the seventh rotating member 37g to rotate, so that the first delay protrusion 371g on the seventh rotating member 37g rotates from a position not in contact with the second delay protrusion 381g to a position in contact with the first delay protrusion 371g, and then the power of the seventh rotating member 37g is transmitted to the eighth rotating member 38g through the contact between the first delay protrusion 371g and the second delay protrusion 381g, and the eighth rotating member 38g then transmits the power to the second third rotating member 332g, and finally transmits the power to the first detected member 41f and the second detected member through the transmission assembly to realize the detection process.

[0334] In some embodiments, the seventh rotating member 37g and the eighth rotating member 38g may be disposed between any two of the third rotating members 33 that are engaged with each other.

[0335] Through the above design, when the driving part 21 receives the power output by the image forming device and rotates, the transmission rotating member 35f will not rotate synchronously with the rotation of the driving part 21. Thus, the contact time between the first transmission protrusion 351f and the first driven part 412f in the initial state is prolonged, that is, the duration of the first detected member 41f being kept in the detection position under the action of the first transmission protrusion 351f is prolonged, so that the length of the first transmission protrusion 351f in the circumferential direction in this embodiment can be set to be the same as the length of the second transmission protrusion 352f and the third transmission protrusion 353f in the circumferential direction. .

[0336] Embodiment eight:

[0337] Unless otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the first embodiment.

[0338] like Figure 47 to Figure 55 As shown, the difference between this embodiment and the first embodiment is that the transmission assembly includes a first rotating member 31h, a second rotating member 32h, a transmission rotating member 35h and a flexible member 36h.

[0339] like Fig.47 and Fig.48 As shown, the second tooth portion 312h is configured as cylindrical pin teeth arranged on the circumferential surface of the first rotating member 31h around the rotation direction of the first rotating member 31h, and the cylindrical pin teeth extend along the radial direction of the first rotating member 31h toward a direction away from the rotation axis of the first rotating member 31h.

[0340] The third tooth portion 321h is configured as a cylindrical pin tooth shape arranged on the circumferential surface of the second rotating member 32h around the rotation direction of the second rotating member 32h, and the missing tooth portion is provided on the third tooth portion 321h, and the third tooth portion 321h is engaged with the second tooth portion 312h.

[0341] The second rotating member 32h is provided with a first pulley portion 322h to replace the fourth tooth portion.

[0342] In this embodiment, the flexible member 36h receives power from the first end 11 and moves. Specifically, the flexible member 36h transmits power from the second rotating member 32h to the transmission rotating member 35h. The flexible member 36h is at least partially located between the first end 11 and the second end 12 and at least partially moves in the first direction. The flexible member 36h is preferably a transmission belt.

[0343] like Fig.48 As shown, the transmission rotating member 35h is provided with a second pulley portion 351h to replace the transmission tooth portion. The flexible member 36h (transmission belt) is installed on the first pulley portion 322h and the second pulley portion 351h to form a belt transmission mechanism to achieve power transmission.

[0344] like Fig.48 and Fig.49 As shown, the fifth end 15 is also fixedly provided with an abutment member, which includes a first abutment protrusion 152h, a second abutment protrusion 153h, a third abutment protrusion 154h and a delay protrusion 151h, wherein the first abutment protrusion 152h has a first inclined surface 1521h, the second abutment protrusion 153h has a second inclined surface 1531h, and the third abutment protrusion 154h has a third inclined surface 1541h, and the first abutment protrusion 152h, the second abutment protrusion 153h, the third abutment protrusion 154h and the delay protrusion 151h are arranged in a ring shape and the first abutment protrusion 152h, the second abutment protrusion 153h, and the third abutment protrusion 154h are spaced from each other in the circumferential direction. The delay protrusion 151h is in contact with the third abutment protrusion 154h. The length of the delay protrusion 151h in the circumferential direction is greater than that of the first abutting protrusion 152h, the second abutting protrusion 153h, and the third abutting protrusion 154h. The first inclined surface 1521h, the second inclined surface 1531h, and the third inclined surface 1541h all intersect with the second direction. The angle between the first inclined surface 1521h and the second direction is B1, the angle between the second inclined surface 1531h and the second direction is B2, and the angle between the third inclined surface 1541h and the second direction is B3. <B2、B1。

[0345] like Fig.50 As shown, a first abutment portion 354h for contacting the abutment member is provided on the transmission rotating member 35h. When the transmission rotating member 35h receives power transmitted by the flexible member 36h, the first abutment portion 354h rotates along with the transmission rotating member 35h. When the first abutment portion 354h rotates, it contacts the abutment member and moves in the third direction under the force provided by the abutment member.

[0346] like Fig.48 and Fig.50 As shown, a rotating shaft protruding upward in the third direction is fixedly provided on the fifth end 15, and the transmission rotating member 35h rotates around the rotating shaft. A mounting hole is coaxially provided on the rotating shaft, and a limiting member 39h is installed in the mounting hole. As an embodiment, the limiting member 39h is connected to the mounting hole by a threaded connection. A limiting portion 391h is provided on the upper end of the limiting member 39h, and the limiting portion 391h is in the shape of a disc. A mounting groove 353h is provided on the transmission rotating member 35h, and the mounting groove 353h is in the shape of a downwardly concave circular ring. A first elastic member 38h is provided in the mounting groove 353h. The first elastic member 38h can be a compression spring, and one end of the first elastic member 38h abuts against the limiting portion 391h and the other end abuts against the mounting groove 353h. The first elastic member 38h is used to apply a downward force to the transmission rotating member 35h so that the first abutting portion 354h maintains close contact with the abutting member.

[0347] like Fig.48As shown, a transmission rib 352h is further provided on the outer circumferential surface of the transmission rotating member 35h. The transmission rib 352h is annular and protrudes radially away from the rotation axis of the transmission rotating member 35h.

[0348] like Fig.48 and Fig.51 As shown, the second end 12 is detachably mounted with a second protective cover 121, and a guide post 1211h is fixedly mounted on the second protective cover 121. The guide post 1211h extends upward along the third direction, and a trigger 37h is slidably mounted on the guide post 1211h. A sliding hole 373h is arranged on the trigger 37h along the third direction, and the sliding hole 373h is inserted into the guide post 1211h and slides with the guide post 1211h. A leftward recessed slide groove 371h is arranged at the right end of the trigger 37h, and the slide groove 371h slides with the transmission rib 352h, so that the trigger 37h can move up and down in the third direction together with the transmission rotating member 35h. A first transmission inclined surface 372h is arranged on the trigger 37h, and the first transmission inclined surface 372h intersects with the third direction, and the front end of the first transmission inclined surface 372h is lower than the rear end.

[0349] like Fig.48 and Fig.51 As shown, the second protective cover 121 is also fixedly provided with a first track 1212h for installing the detected member 4h. The detected member 4h is slidably installed in the first track 1212h and can slide back and forth in the second direction along the first track 1212h. A second elastic member 43h is installed between the rear end of the detected member 4h and the first track 1212h. The second elastic member 43h is used to make the detected member 4h have a tendency to slide forward. The second elastic member 43h is a compression spring. The front end of the second elastic member 43h abuts against the rear end of the detected member 4h, and the rear end of the second elastic member 43h abuts against the rear end of the first track 1212h.

[0350] The detected member 4h is provided with a second transmission slope 42h for contacting the first transmission slope 372h, the second transmission slope 42h intersects with the third direction, and the front end of the second transmission slope 42h is lower than the rear end. The front end of the detected member 4h is a triggering part 41h.

[0351] The specific detection process is as follows:

[0352] like Figure 52 to Figure 55 As shown, the first rotating member 31h transmits power to the second rotating member 32h through the combination of the second tooth portion 312h and the third tooth portion 321h, the second rotating member 32h drives the flexible member 36h to move, and the flexible member 36h drives the transmission rotating member 35h to rotate.

[0353] In the initial position, the first abutting portion 354h of the transmission rotating member 35h abuts against the upper end of the third delay protrusion 151h and is located at the upstream end of the third delay protrusion 151h in the rotation direction of the transmission rotating member 35h.

[0354] As the transmission rotating member 35h rotates, the first abutting portion 354h rotates along the third delay protrusion 151h. During this process, the triggering member 37h is located at the first position, the detected member 4h is at the detecting position, and the triggering portion 41h touches the detecting member.

[0355] As the transmission rotating member 35h rotates, the first abutment portion 354h rotates to the gap between the third delay protrusion 151h and the first abutment protrusion 152h. Under the elastic force of the first elastic member 38h, the transmission rotating member 35h moves downward, driving the trigger member 37h to move downward from the first position to the second position, so that the first transmission inclined surface 372h applies a force to the second transmission inclined surface 42h, so that the detected member 4h overcomes the elastic force of the second elastic member 43h and moves backward, thereby moving from the detection position to the non-detection position.

[0356] As the transmission rotating member 35h rotates, the first abutment portion 354h rotates to the first abutment protrusion 152h and moves upward along the first inclined surface 1521h on the first abutment protrusion 152h, thereby driving the transmission rotating member 35h to move upward, so that the trigger member 37h moves from the second position to the first position together with the transmission rotating member 35h, so that the first transmission inclined surface 372h gradually disengages from the second transmission inclined surface 42h, so that the detected member 4h moves from the non-detection position to the detection position under the elastic force of the second elastic member 43h.

[0357] As the transmission rotating member 35h rotates, the first abutment portion 354h rotates to the gap between the first abutment protrusion 152h and the second abutment protrusion 153h. Under the elastic force of the first elastic member 38h, the transmission rotating member 35h moves downward, driving the trigger member 37h to move downward from the first position to the second position, thereby causing the detected member 4h to move from the detection position to the non-detection position.

[0358] As the transmission rotating member 35h rotates, the first abutting portion 354h abuts against the second abutting protrusion 153h. The abutment and disengagement of the two are the same as those of the first abutting protrusion 152h, which will not be repeated here.

[0359] As the transmission rotating member 35h rotates, the first abutment portion 354h rotates to the third abutment protrusion 154h and moves upward along the third inclined surface 1541h on the third abutment protrusion 154h, thereby driving the transmission rotating member 35h to move upward, so that the trigger member 37h moves from the second position to the first position together with the transmission rotating member 35h, so that the first transmission inclined surface 372h gradually disengages from the second transmission inclined surface 42h, so that the detected member 4h moves from the non-detection position to the detection position under the elastic force of the second elastic member 43h. And because the angle between the third inclined surface 1541h and the second direction is smaller than the angle between the first inclined surface 1521h and the second direction and the angle between the second inclined surface 1531h and the second direction, the moving speed V3 of the first contact portion 354h in the vertical direction when moving upward along the third inclined surface 1541h is greater than the moving speeds V1 and V2 of the first contact portion 354h in the vertical direction when moving upward along the first inclined surface 1521h and the second inclined surface 1531h. Therefore, the triggering member 37h moves upward at the speed V3, and the speed at which the detected member 4h moves from the non-detection position to the detection position is also faster.

[0360] As the transmission rotating member 35h rotates, the first abutment portion 354h rotates again to the upstream end of the third delay protrusion 151h in the rotation direction of the transmission rotating member 35h, and at the same time, the toothless portion of the second rotating member 32h rotates to a position opposite to the second tooth portion 312h to stop receiving power, so that the transmission component has no power input, the detected member 4h stops moving, and the detection process is completed. That is, in this embodiment, the transmission rotating member 35h acts as an intermediate member to enable the flexible member 36h to drive the detected member 4h to move.

[0361] The flexible member in this embodiment is used to replace the third rotating member and the fourth rotating member, so as to reduce the number of parts and the space occupation rate, so that the box body 10 can be designed to be larger and the developer capacity can be increased.

[0362] Embodiment nine:

[0363] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment.

[0364] like Fig.56 As shown, the difference between this embodiment and the eighth embodiment is that:

[0365] The fifth end 15 is provided with a cylindrical first connecting column 151i (transmission rotating member) protruding upward, and the flexible member 36i is movably sleeved between the second rotating member 32i and the first connecting column 151i, and the first connecting column 151i can be rotating or non-rotating;

[0366] The flexible member 36i is provided with a first protrusion 361i, a second protrusion 362i, a third protrusion 363i, and a fourth protrusion 364i in sequence with intervals therebetween.

[0367] The length of the first protrusion 361i in the first direction is greater than the lengths of the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i in the first direction.

[0368] The second protrusion 362i is provided with a first inclined surface 3621i, the third protrusion 363i is provided with a second inclined surface 3631i, and the fourth protrusion 364i is provided with a third inclined surface 3641i.

[0369] The first inclined surface 3621i, the second inclined surface 3631i, and the third inclined surface 3641i all intersect with the first direction. And the angle between the third inclined surface 3641i and the first direction is greater than the angle between the second inclined surface 3631i and the third inclined surface 3641i and the first direction. The detected member is a rocker structure, and its swing axis intersects with the first direction. The driven member 42i of the detected member extends to the middle of the box body 10 in the first direction, and a driven protrusion 421i (equivalent to the first driven part, the second driven part, the third driven part, and the fourth driven part) is provided on the driven member 42i of the detected member. This embodiment provides another implementation of the reset elastic member 1521i, specifically, the reset elastic member 1521i is a compression spring, and a groove 152i for installing the reset elastic member 1521i is provided on the fifth end 15, and the groove 152i is formed by being recessed downward, and a reset protrusion 423i protruding downward is provided on the driven member 42i, and the reset protrusion 423i is inserted into the groove 152i and can slide relative to the groove 152i, and one end of the reset elastic member 1521i abuts against the reset protrusion 423i and the other end abuts against the rear end of the groove 152i.

[0370] As the flexible member 36i moves, the first protrusion 361i, the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i move leftward in the first direction together with the flexible member 36i, and apply a force to the driven protrusion 421i in turn, so that the driven protrusion 421i drives the detected member to move and the triggering part 41i triggers the detecting member. After any one of the first protrusion 361i, the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i passes through the driven protrusion 421i, the detected member can be restored from the detection position to the non-detection position under the elastic force of the reset elastic member 1521i, so that the detecting member can be restored from the triggered state to the non-triggered state multiple times.

[0371] Embodiment ten:

[0372] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment.

[0373] like Fig.57 As shown, the difference between this embodiment and the eighth embodiment is that the transmission block, abutment member and other structures are eliminated.

[0374] In this embodiment, the transmission rotating member 35j is rotatably disposed on the second protective cover 121, the rotation axis of the transmission rotating member 35j is parallel to the third direction, and the transmission rotating member 35j, the second rotating member 32h and the flexible member 36h constitute a belt transmission system, that is, in this embodiment, the flexible member 36h extends from the first end 11 to the second end 12. The triggering portion 41j is fixedly disposed together with the transmission rotating member 35j and can rotate together with the transmission rotating member 35j to make a circular motion.

[0375] In this embodiment, the diameter of the transmission rotating member 35j is smaller than the diameter of the second rotating member 32h, and the transmission ratio between the second rotating member 32h and the transmission rotating member 35j is 1:4, so that the second rotating member 32j rotates one circle and the transmission rotating member 35j rotates four circles, thereby causing the triggering part 41j to move four times from a non-detection position that does not contact the detection member to a detection position that contacts the detection member, thereby completing four triggering of the detection member.

[0376] In some embodiments, the triggering part may also be arranged on the transmission rotating member, and the triggering part may be single or multiple.

[0377] Embodiment eleven:

[0378] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment.

[0379] like Fig.58 As shown, the detected member 4m is rotatably mounted on an upwardly protruding pivot column 1211m on the second protective cover 121, a lever 352m is fixedly provided on the transmission rotating member 35m and extends radially in a direction away from the rotation axis of the transmission rotating member 35m, and a driven groove 42m is provided on the driven member of the detected member 4m, and the lever 352m is inserted into the driven groove 42m. A reset elastic member 1212m is also installed on the second protective cover. The reset elastic member 1212m is sleeved on an upward protrusion provided on the second protective cover 121. One end of the reset elastic member 1212m abuts against the reset protrusion 353m on the circumferential surface of the transmission rotating member 35m, and the other end abuts against the first limiting protrusion 1213m protruding upward on the second protective cover 121 to limit the rotation of the reset elastic member 1212m. The reset elastic member 1212m is used to provide counterclockwise rotation force to the transmission rotating member 35m, and the flexible member 36h provides clockwise rotation force to the transmission rotating member 35m.

[0380] When the transmission rotating member 35m rotates following the movement of the flexible member 36h, the transmission rotating member 35m drives the detected member 4m to swing back and forth through the shifting rod 352m.

[0381] Embodiment 12:

[0382] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment.

[0383] The difference between this embodiment and the eighth embodiment is that the structure of the transmission assembly is different. The transmission assembly includes a first rotating member 31n, a second rotating member 32n, a flexible member 36n, and a translation member 37n.

[0384] like Figure 59-Figure 61 As shown, the second rotating member 32n is located at the first end 11, and the second rotating member 32n includes a third tooth portion 321n (bevel teeth) and a first winding portion 322n, the first winding portion 322n (equivalent to the fourth tooth portion), the third tooth portion 321n is engaged with the second tooth portion 312n (bevel teeth) of the first rotating member 31d so that the second rotating member 32n rotates following the first rotating member 31d, and the third tooth portion 321n includes a missing tooth portion 3211n, which is used to disconnect the engagement with the first rotating member 31d, that is, the second rotating member 32n no longer rotates following the first rotating member 31d. The first winding portion 322n is preferably cylindrical, and in some embodiments, the first winding portion 322n can also be other shapes such as a prism, and the first winding portion 322n is provided with a first connecting portion 3221n, and the first connecting portion 3221n is hole-shaped.

[0385] like Fig.59 and Fig.60 As shown, the flexible member 36n is movably mounted on the box body 10, the flexible member 36n extends in the first direction, the flexible member 36n at least partially performs linear motion in the first direction, the flexible member 36n includes a first end 361n and a second end 362n in the first direction, the first end 361n is arranged near the first end 11, the second end 362n is arranged near the second end 12, the first end 361n can be wound on the first winding portion 322n, the first end 361n is first connected to the first connecting portion 3221n of the first winding portion 322n by bundling, welding, gluing, etc. to prevent the flexible member 36n from being separated from the second rotating member 32n, and then continuously wound on the first winding portion 322n during the rotation of the second rotating member 32n. The flexible member 36n has the characteristics of being incompressible or stretchable (incompressible or stretchable includes being slightly compressed and stretched), that is, being inelastically deformable, but being bendable, the flexible member can be a common rope, or other components such as copper wire, steel wire rope, etc., as long as they have the above characteristics, in this embodiment, the flexible member 36n is preferably a steel wire rope.

[0386] like Fig.60 and Fig.61As shown, the box body 10 is provided with a mounting groove (not shown) which is recessed in the third direction and extends in the first direction. The translation member 37n is movably installed in the mounting groove, and the translation member 37n can move in the first direction. The translation member 37n includes a driving protrusion 371n and a second connecting portion 372n. The second connecting portion 372n is used to be fixedly connected with the second end 362n of the flexible member 36n by bundling, welding, gluing, etc. The second connecting portion 372n preferably extends in the first direction and has a groove recessed in the radial direction. The size of the second connecting portion 372n is matched with the size of the flexible member 36n. The translation member 37n can move with the flexible member 36n, specifically, in the first direction, it moves in the direction close to the first end 11 (moves to the right). The driving protrusion 371n is a protrusion extending in the third direction. In this embodiment, it preferably extends downward along the third direction. In other embodiments, it can extend upward. The driving protrusion 371n is provided with an abutting surface, which is preferably an inclined surface, or a curved surface or a straight surface.

[0387] like Figure 59 to Figure 61 As shown, the detected member 4n is swingably mounted on the second protective cover 121, and the detected member 4n includes a driven member 42n, a supported portion 43n and a trigger portion 41n. The driven member 42n is provided with a first driven portion 421n and a second driven portion 422n. In the first direction, the first driven portion 421n is farther away from the first end 11 than the second driven portion 422n, and there is a gap between the first driven portion 421n and the second driven portion 422n in the first direction. The first driven portion 421n and the second driven portion 422n are protrusions extending upward in the third direction, and both are preferably provided with abutted surfaces, which are preferably inclined surfaces, and may also be curved surfaces or straight surfaces. The supported portion 43n is hole-shaped, and the supported portion 43n is supported by the second protective cover 121, and the supported portion 43n is the swing center of the detected member 4n. When the factory is preset, the driving protrusion 371n is located on the left side of the first driven portion 421n.

[0388] like Fig.60 As shown, the developer box 1 also includes a reset elastic member 45n. In this embodiment, the reset elastic member 45n is preferably a compression spring, and can also be an elastic medium such as sponge. The reset elastic member 45n is used to make the detected member 4n swing in the opposite direction to reset (move from the detection position to the non-detection position).

[0389] like Figure 59 to Figure 61As shown, when the driving assembly receives the power output by the image forming device, the second rotating member 32n starts to rotate following the first rotating member 31d, and the first end 361n of the flexible member 36n is further wound around the first winding portion 322n, so that the flexible member 36n makes a linear motion to the right in the first direction and drags the translation member 37n to translate (move to the right) in the first direction toward the direction close to the first end 11. The driving protrusion 371n abuts against the first driven portion 421n of the detected member 4n, so that the detected member 4n swings, the triggering portion 41n swings up to the detection position to trigger the detection member, and the reset elastic member 45n is compressed. As the second rotating member 32n rotates further, more parts of the flexible member 36n are wound around the first winding portion, the translation member 37n moves further to the right, the driving protrusion 371n is disengaged from the abutment with the first driven portion 421n, and the detected member 4n swings in the opposite direction under the elastic action of the reset elastic member 45n to reset to the non-detection position. After the translation member 37n continues to translate, it abuts against the second driven part 422n, causing the detected part 4n to swing to the detection position again and trigger the detection part again. After the second abutment, the detected part 4n is disengaged from the translation member 37n, and the detected part 4d is reset and no longer swings, the toothless part 3211n of the second rotating part 32n is opposite to the second tooth part 312n of the first rotating part 31n, the second rotating part 32n is disengaged from the first rotating part 31n, the second rotating part 32n stops rotating, and the flexible part 36n no longer moves in the first direction. In this embodiment, the diameter of the flexible part 36n is preferably not greater than 1mm, and can be set according to actual needs in other embodiments. In this embodiment, the number, size, and spacing of the driven parts on the detected part can be set according to actual needs. That is, in this embodiment, the translation member 37n is used as an intermediate member to enable the flexible part 36n to drive the detected part 4n to move.

[0390] It can be known that the length formed by the distance that the flexible member 36n moves in the first direction is the same as or similar to the length formed by the rotation of the third tooth portion 321n of the second rotating member 32n.

[0391] Embodiment 13:

[0392] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the twelve embodiment.

[0393] like Fig.62 and Fig.63 As shown, the difference between this embodiment and the twelfth embodiment is that the structure of the transmission assembly is different, and the transmission assembly includes a first rotating member, a second rotating member 32n, a transmission rotating member 35p and a flexible member 36n.

[0394] like Fig.62 and Fig.63As shown, in this embodiment, the second rotating member 32n is not provided with a missing tooth portion, and the missing tooth portion is provided on the first tooth portion of the first rotating member. The second rotating member 32n is fixedly provided with a first winding portion 322n extending upward and in a cylindrical shape. The transmission rotating member 35p is provided with a first transmission protrusion 351p, a second transmission protrusion 352p, and a third transmission protrusion 353p that move with the transmission rotating member 35p at intervals in the circumferential direction. The transmission rotating member 35p is fixedly provided with a second winding portion 354p extending upward and in a cylindrical shape. A flexible member 36n is provided between the first winding portion 322n and the second winding portion 354p. The first end of the flexible member 36n is fixedly connected to the first winding portion 322n, and the second end is fixedly connected to the second winding portion 354p. In the initial state, the flexible member 36n is wound around the second winding portion 354p so that the flexible member 36n is in a tight state between the first winding portion 322n and the second winding portion 354p.

[0395] like Fig.63 As shown, the second protective cover 121 is provided with a track 1211p extending in the first direction, the detected member 4p can slide along the first track 1211p and displace in the first direction relative to the box body 101, and the detected member 4p includes a triggering portion 41p, a third sliding portion 43p, and a driven member 42p which are fixedly connected together from left to right. The third sliding portion 43p is installed in the first track 1211p and can slide along the first track 1211p in the first direction.

[0396] The left wall of the first track 1211p is provided with a second hole, and the trigger part 41p can extend leftward from the second hole to touch the detection member. The trigger part 41p is provided with a detected inclined surface 411p, and the inclined direction of the detected inclined surface 411p is set so that the left end is further back than the right end.

[0397] The driven member 42p is touched and driven by the first transmission protrusion 351p, the second transmission protrusion and the third transmission protrusion 353p. A driven inclined surface 421p is provided on the driven member 42p, and the inclined direction of the driven inclined surface 421p intersects with the first direction and the second direction.

[0398] A first abutment portion 44p extending upward is also provided at the upper end of the third sliding portion 43p, and a reset elastic member is installed between the first abutment portion 44p and the left wall of the first rail 1211p, the left end of the reset elastic member 45p abuts against the left wall of the first rail 1211p, and the right end of the reset elastic member 45p abuts against the first abutment portion 44p, and the reset elastic member is used to keep the detected member 4p in the non-detection position or have a tendency to move rightward to the non-detection position.

[0399] The second rotating member 32n is driven to rotate by the first rotating member, so that the first winding portion 322n pulls the flexible member 36n to make linear motion in the first direction. Since the flexible member 36n is wound around the second winding portion 354p in the initial state, when the flexible member 36n is pulled, the second winding portion 354p drives the transmission rotating member 35p to rotate counterclockwise (viewed from top to bottom), and the flexible member 36n is gradually wound around the first winding portion 322n.

[0400] When the transmission rotating member 35p rotates, the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p sequentially touch the driven inclined surface 421p of the driven member 42p. Through the action of the driven inclined surface 421p, the force applied by the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p is partially converted into a leftward force in the first direction, so that the detected member 4p moves leftward from the non-detection position to the detection position, so that the detected inclined surface 411p triggers the detection member, and the first abutment portion 44p compresses the reset elastic member 45p. That is, in this embodiment, the transmission rotating member 35p serves as an intermediate member to enable the flexible member 36h to drive the detected member 4h to move.

[0401] When the driven member 42p is out of contact with the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p, under the elastic force of the reset elastic member 45p, the detected member 4p moves rightward from the detection position to the non-detection position, thereby stopping triggering the detection member.

[0402] Embodiment 14:

[0403] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the thirteenth embodiment.

[0404] like Fig.64 and Fig.65 As shown, the difference between this embodiment and the thirteenth embodiment is that the first transmission protrusion 351q, the second transmission protrusion 352q and the third transmission protrusion 353q are respectively provided with a first transmission bevel 3511q, a second transmission bevel 3521q and a third transmission bevel 3531q, and the first transmission bevel 3511q, the second transmission bevel 3521q and the third transmission bevel 3531q all extend around the circumferential direction of the transmission rotating member 35q. In the rotation direction of the transmission rotating member 35q, the first transmission bevel 3511q, the second transmission bevel 3521q and the third transmission bevel 3531q have the same inclination direction. The inclination direction of the first transmission bevel 3511q is taken as an example to illustrate the inclination direction. The inclination direction of the first transmission bevel 3511q is set so that the upstream end of the first transmission bevel 3511q is higher than the downstream end in the rotation direction of the transmission rotating member 35q.

[0405] like Fig.64 As shown, in this embodiment, the first track 1211q extends in the third direction, the detected member 4q is slidably mounted in the first track 1211q and slides along the first track 1211q in the third direction and moves relative to the box body 101. The driven member 42q extends rightward from the first track 1211q and is located on the moving path of the first transmission slope 3511q, the second transmission slope 3521q, and the third transmission slope 3531q, and the triggering portion 41q extends leftward from the first track 1211q.

[0406] When the flexible member 36q drives the transmission rotating member 35q to rotate, the first transmission inclined surface 3511q, the second transmission inclined surface 3521q and the third transmission inclined surface 3531q rotate together with the transmission rotating member 35q and contact the driven member 42q of the detected member 4q in turn, thereby providing a force with a component in the upward direction to the driven member 42q, so that the detected member 4q moves upward from the non-detection position to the detection position to trigger the detection member.

[0407] like Fig.64 As shown, the first transmission protrusion 351q, the second transmission protrusion 352q, and the third transmission protrusion 353q are arranged at intervals in the rotation direction of the transmission rotating member 35q. During the rotation of the transmission rotating member 35q, the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q of the transmission rotating member 35q will all be out of contact with the driven member 42q after contacting with the driven member 42q.

[0408] A reset elastic member 45q is installed between the upper end of the detected member 4q and the upper wall of the first track 1211q, and the reset elastic member 45q is used to provide a downward elastic force to the detected member 4q so that the detected member 4q can be kept in a non-detection position when not subjected to other forces or has a tendency to move to the non-detection position. When the driven member 42q is out of contact with the first transmission slope 3511q, the second transmission slope 3521q, and the third transmission slope 3531q, under the action of the reset elastic member 45q, the detected member 4q moves downward from the detection position to the non-detection position and stops triggering the detection member. In this embodiment, the upper wall of the first track 1211q is formed by an abutment plate 1212q, and the abutment plate 1212q is fixedly mounted to the upper end of the first track 1211q by welding or snapping, thereby closing the opening at the upper end of the first track 1211q.

[0409] like Fig.64 and Fig.65As shown, in this embodiment, a connection method between the flexible member 36q and the second rotating member 32q is disclosed, the first winding portion 322q of the second rotating member 32q is coaxially provided with a first disk body 323q on the upper end, the radius of the first disk body 323q is larger than the first winding portion 322q, and the first disk body 323q is provided with a plug-in portion 324q, the plug-in portion 324q is formed by extending from the outer circumferential surface of the first disk body 323q along the radial direction of the first disk body 323q toward the direction of the rotation axis of the first disk body 323q, and the plug-in portion 324q has a first limiting wall 3241q and a second limiting wall 3241q and a second limiting wall 3241q arranged opposite to each other in the circumferential direction. The limiting wall 3242q, the first limiting wall 3241q is provided with a first limiting protrusion 3243q at one end away from the rotation axis of the first disk body 323q in the radial direction, the second limiting wall 3242q is provided with a second limiting protrusion 3244q at one end away from the rotation axis of the first disk body 323q in the radial direction, the first limiting protrusion 3243q and the second limiting protrusion 3244q are arranged opposite to each other, there is a first interval between the first limiting protrusion 3243q and the second limiting protrusion 3244q in the circumferential direction, and there is a second interval greater than the first interval between the first limiting wall 3241q and the second limiting wall 3242q in the circumferential direction. The surface opposite to the first limiting protrusion 3243q and the second limiting protrusion 3244q is an arc surface.

[0410] like Fig.64 and Fig.65 As shown, the first end of the flexible member 36q is fixedly connected with the insertion portion 361q, the insertion portion 361q includes a rod portion 3611q and a first limiting portion 3612q, the rod portion 3611q extends in the third direction, the first limiting portion 3612q is fixedly arranged at the upper end of the rod portion 3611q, and the lower end of the rod portion 3611q is fixedly connected to the right end of the flexible member 36q (such as welding, bonding, tight fitting, etc.). The diameter of the first limiting portion 3612q is greater than the diameter of the rod portion 3611q and the second interval, the diameter of the rod portion 3611q is greater than the first interval and less than or equal to the second interval, and in this embodiment, the diameter of the rod portion 3611q is preferably equal to the second interval.

[0411] like Fig.64 and Fig.65As shown, when the insertion portion 361q is inserted into the plug-in portion 324q, the rod portion 3611q is aligned with the first spacing between the first limiting protrusion 3243q and the second limiting protrusion 3244q, and the rod portion 3611q is pressed radially toward the direction close to the rotation axis of the first rotating member. Since the radius of the rod portion 3611q is greater than the first spacing, the first limiting protrusion 3243q and the second limiting protrusion 3244q are elastically deformed when the rod portion 3611q is pressed. , resulting in the increase of the first interval, so that the rod 3611q can smoothly pass over the first limiting protrusion 3243q and the second limiting protrusion 3244q and enter between the first limiting wall 3241q and the second limiting wall 3242q. Since the diameter of the rod 3611q is equal to the second interval, the rod 3611q is limited by the first limiting wall 3241q and the second limiting wall 3242q in the circumferential direction, thereby preventing the rod 3611q from moving relative to the first rotating member in the circumferential direction. At the same time, when the rod 3611q is subjected to a force in the radial direction away from the rotation axis of the first rotating member, it is necessary to provide a force sufficient to cause the first limiting protrusion 3243q and the second limiting protrusion 3244q to produce elastic deformation before it can be separated from the plug-in part 324q, so that the insertion part 361q can be limited in the radial direction to prevent the insertion part 361q from being separated from the plug-in part 324q.

[0412] Those skilled in the art can easily think of that the insertion portion 331q can also be arranged at the second end portion (left end) of the flexible member 36q, and the plug-in portion 324q can also be arranged on the transmission rotating member 35q, so as to facilitate installation and assembly.

[0413] Embodiment 15:

[0414] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the twelve embodiment.

[0415] like Figures 66 to 74 As shown, the difference between this embodiment and the twelfth embodiment is that the driving assembly and the transmission assembly are different.

[0416] like Fig.67As shown, in this embodiment, the driving assembly further includes a first idler wheel 25r and a second idler wheel 26r, both of which are rotatably supported by the box body 10, and the first idler wheel 25r includes a first large tooth portion 251r and a first small tooth portion 252r, and in the first direction, the first small tooth portion 252r is closer to the first end 11 than the first large tooth portion 251r. The second idler wheel 26r includes a second large tooth portion 261r and a second small tooth portion 262r, and in the first direction, the first large tooth portion 251r is farther away from the first end 11 than the first small tooth portion 252r, the first large tooth portion 251r is meshed with the driving gear 212 to receive power and rotate, the first small tooth portion 252r is meshed with the second large tooth portion 261r to transmit power to the second idler wheel 26r, and the second large tooth portion 261r includes a missing tooth portion 2611r, and the missing tooth portion 2611r is used to disconnect the transmission from the first idler wheel 25r.

[0417] like Figures 66 to 70 As shown, the transmission assembly includes a transmission member 31r and a flexible member 36r. In the first direction, the distance between the transmission member 31r and the second end 12 is greater than the distance between the transmission member 31r and the first end 11. Preferably, the transmission member 31r is rotatably located at the first end 11, and its rotation axis extends in the first direction. The transmission member 31r includes a first tooth portion 311r and a first connecting portion 313r. The first connecting portion 313r is arranged on the end face of the first tooth portion 311r away from the first end 11. The first connecting portion 313r is a protrusion extending in the first direction, preferably a cylindrical protrusion. The first connecting portion 313r is set to deviate from the rotation axis of the transmission member 31r (i.e., eccentrically set). The first tooth portion 311r is meshed with the second small tooth portion 262r to receive power and rotate. This embodiment does not limit the number of gears of the drive assembly and the meshing relationship between the gears, and can be set according to actual needs.

[0418] like Figures 66 to 70As shown, in this embodiment, the flexible member 36r serves as a detected member to directly trigger the detection member 900. The flexible member 36r extends in the first direction and is movably supported by the box body 10. The box body 10 is provided with a guide groove extending in the first direction, which can guide the flexible member 36r to perform linear movement in the first direction. The box body 10 is also provided with a first fixing portion 115, which is used to prevent the flexible member 36r from falling off. The first fixing portion 115 is preferably a through hole extending in the first direction. The first fixing portion 115 is arranged at the fourth end 14. The flexible member 36r passes through the first fixing portion 115 and can move relative to the first fixing portion 115. The first fixing portion 115 can be single or multiple, and multiple is preferred in this embodiment. The flexible member 36r includes a first section 361r and a second section 363r. The first section 361r is located at the first end 11 and extends in a direction close to the developing roller 131. The first section 361r is provided with a second connecting portion 362r. The second connecting portion 362r is an end of the flexible member 36r. The second connecting portion 362r is a hole-shaped portion. The second connecting portion 362r cooperates with the first connecting portion 313r to connect the flexible member 36r with the transmission member 31r. When the transmission member 31r rotates, the flexible member 36r moves relative to the box body 10, and at least part of the flexible member 36r moves linearly in the first direction. The second connecting portion 362r can follow the transmission member 31r to move between the first position and the second position. In the second direction, the first position is farther away from the developing roller 131 than the second position.

[0419] like Fig.69 and Fig.70As shown, the second section 363r is located at the second end 12 and extends in the direction close to the developing roller 131. The second end 12 is provided with a second protective cover 121, and the second section 363r is movably supported by the second protective cover 121. The second protective cover 121 is provided with a second fixing portion 1211r, which is a through hole, and the second fixing portion 1211r is used to prevent the second section 363r from falling off. The second protective cover 121 is provided with a first supporting portion 1212r and a second supporting portion 1213r. Along the second direction, the first supporting portion 1212r is farther away from the developing roller 131 than the second supporting portion 1213r, and the first supporting portion 1212r is arranged adjacent to the second fixing portion 1211r. The second protective cover 121 is also provided with a plurality of second limiting protrusions 1214r that prevent the second section 363r from detaching. The plurality of second limiting protrusions 1214r are staggeredly distributed, and the second section 363r is located between the plurality of second limiting protrusions 1214r. The second protective cover 121 is provided with a third connecting portion 1215r adjacent to the second supporting portion 1213r, and the third connecting portion 1215r is preferably a cylindrical protrusion. The second section 363r includes a triggering portion 364r and a fourth connecting portion 365r, the fourth connecting portion 365r is the other end of the flexible member 36r, and the fourth connecting portion 365r is a hole-shaped portion. The third connecting portion 1215r and the fourth connecting portion 365r cooperate to make the second section 363r fixed by the second protective cover 121. In this embodiment, the height of the connection between the third connecting portion 1215r and the fourth connecting portion 365r is preferably lower than the height of the second supporting portion 1213r in the third direction. Along the second direction, the triggering portion 364r is at least partially located between the first supporting portion 1212r and the second supporting portion 1213r, and the triggering portion 364r is used to trigger the detection member 900 so that the image forming device recognizes the developing box 1. The triggering portion 364r has a relaxed state in which the detection member 900 is not triggered and a tight state in which the detection member 900 is triggered. When the second connection portion 362r is located at the first position, the trigger portion 364r is in a relaxed state, and when the second connection portion 362r rotates to the second position following the transmission member 31r, the trigger portion 364r is in a tight state. In some embodiments, the first support portion 1212r and the second support portion 1213r can be directly disposed on the box body 10, and can be located at the second end 12.

[0420] The following is the process of the flexible member 36r triggering the detection member 900 in this embodiment:

[0421] like Figure 71 to Figure 74 As shown, when the developing box 1 is installed in the image forming device and the driving part 21 does not receive the power output by the image forming device, the transmission member 31r does not rotate, the flexible member 36r does not move relative to the box body 10, the second connecting part 362r is located at the first position, and the triggering part 364r is in a relaxed state.

[0422] When the driving part 21 starts to receive the power output by the image forming device, the driving part 21 transmits the power to the transmission member 31r, the transmission member 31r starts to rotate and drives the second connection part 362r to start rotating, and the second connection part 362r rotates from the first position to the second position. During this process, the second connection part 362r drives the flexible member 36r to move rightward in the first direction relative to the box body 10, so that the trigger part 364r gradually changes from a relaxed state to a tightened state with the first support part 1212r and the second support part 1213r as support points. During the change process, the flexible member 36r and the first support part 1212r are in sliding contact, and the trigger part 364r directly contacts the detection member 900 and drives the detection member 900 to move. When the second connection part 362r rotates to the second position, the trigger part 364r is in a completely tightened state, and the trigger part 364r completely triggers the detection member 900.

[0423] When the transmission member 31r continues to drive the second connection part 362r to rotate, the second connection part 362r rotates from the second position to the first position. At this time, the trigger part 364r changes from the tight state to the loose state, and the flexible member 36r moves leftward along the first direction under the action of the detection member 900. When the second connection part 362r rotates to the second position following the transmission member 31r, the trigger part 364r changes to the tight state again and triggers the detection member 900 again. After the detection is completed, the transmission member 31r is disengaged from the second idler wheel 26r. This embodiment does not limit the number of detections, which can be set according to actual needs.

[0424] It is known that when the detection member 900 is triggered, the tension state of the trigger portion 364r can be a completely tension state or a partially tension state.

[0425] Optionally, in order to allow the trigger portion 364r to smoothly transition from a tense state to a relaxed state, an elastic member such as a tension spring or a compression spring may be added. The elastic member deforms when triggered, and the elastic force of the elastic member when the trigger is released causes the trigger portion 364r to change state.

[0426] As a variation of this embodiment, the difference is that in this variation, the first section 361r of the flexible member 36r is wound around the transmission member 31r.

[0427] like Figure 75 to Figure 78As shown, the transmission member 31r includes a first tooth portion 311r, a protrusion 314r and a first connecting portion 315r. The first tooth portion 311r is meshed with the second idler wheel 26r to rotate the transmission member 31r. The protrusion 314r is arranged on the end face of the first tooth portion 311r away from the first end 11. The extension direction of the protrusion 314r intersects with the first direction, that is, the protrusion 314r protrudes in the radial direction while protruding relative to the first tooth portion 311r in the first direction, and the top of the protrusion 314r is smaller than the bottom, that is, in this embodiment, the protrusion 314r is roughly eccentric cone-shaped, the bottom is one end of the protrusion 314r close to the first end 11 along the first direction, and the top is the other end along the first direction. A first connection portion 315r is provided at the bottom of the protrusion 314r. The first connection portion 315r is preferably a through hole. The first connection portion 315r is fixedly connected to the second connection portion 362r so that the transmission member 31r is connected to the flexible member 36r. The first section 361r can be wrapped around the protrusion 314r when the transmission member 31r rotates.

[0428] like Figure 75 to Figure 78 As shown, before the transmission member 31r receives power to rotate, the first section 361r is close to the bottom of the protrusion 314r, and the triggering portion 364r of the second end 12 is in a relaxed state. When the transmission member 31r receives power and starts to rotate, the first section 361r gradually wraps around the protrusion 314r, and wraps from the bottom to the direction close to the top. During the winding process of the first section 361r, the flexible member 36r moves rightward along the first direction so that the triggering portion 364r changes from a relaxed state to a tight state and triggers the detection member 900. Since the protrusion 314r is inclined, the first section 361r cannot be wrapped around the protrusion 314r all the time. When the transmission member 31r continues to rotate, the first section 361r wraps around the top of the protrusion 314r, and the first section 361r falls from the top to the bottom. The flexible member 36r moves leftward along the first direction under the action of the detection member 900, and the triggering portion 364r changes from a tight state to a relaxed state and releases the trigger. After the transmission member 31r continues to rotate, the first section 361r is wound from the bottom to the top again. After the transmission member 31r stops rotating, the flexible member 36r remains stationary.

[0429] like Fig.75 and Fig.78 As shown, in this embodiment, a guide member 116 is further provided on the developing box 1. Specifically, the guide member 116 is provided at the first end 11 and is located on the rear side of the transmission member 31r in the second direction. The guide member 116 has a guide groove for the first section 361r to pass through / move, which is used to limit the movement range / position of the first section 361r, so as to facilitate guiding the first section 361r to be wound around the protrusion 314r to drive the flexible member 36r to move along the first direction.

[0430] The other structures of the developing box 1 of this embodiment are the same as those of the first embodiment and will not be described again.

[0431] Embodiment 16:

[0432] Unless otherwise specified, the structure in this embodiment is the same as that in the fifteenth embodiment.

[0433] The difference between this embodiment and the fifteenth embodiment is that the second idler gear 26s and the transmission member 31s are bevel gears, the flexible member 36r is not connected to the transmission member 31s, and the transmission member 31s has a different structure.

[0434] like Figure 79 to Figure 81 As shown, the second idler wheel 26s (equivalent to the first rotating member) includes a second large tooth portion 261s and a second small tooth portion 262s, the second large tooth portion 261s includes a missing tooth portion 2611s, and the second small tooth portion 262s is a bevel tooth. In the first direction, the distance between the transmission member 31s and the second end 12 is greater than the distance between the transmission member 31s and the first end 11, the transmission member 31s includes a first tooth portion 311s and a pressing portion 316s, the first tooth portion 311s is a bevel tooth, the first tooth portion 311s is meshed with the second small tooth portion 262s to receive power and rotate, the rotation axis of the transmission member 31s intersects with the first direction, and in this embodiment, is preferably parallel to the third direction, the pressing portion 316s is a radially protruding protrusion, and the pressing portion 316s is used to press the flexible member 36r.

[0435] like Fig.79 As shown, the first end 11 is provided with a first support column 106, the first support column 106 extends along the third direction, and the transmission member 31s is rotatably supported by the first support column 106. The first end 11 is also provided with a first connecting portion 117, the first connecting portion 117 is fixedly connected to the second connecting portion 362r of the flexible member 36r, and along the second direction, the pressing portion 316s is located between the first connecting portion 117 and the fourth end 14.

[0436] like Figure 79 to Figure 81 As shown, when the transmission member 31s does not rotate, the pressing portion 316s does not contact or only slightly contacts the first section 361r of the flexible member 36r, and the first section 361r located at the first end 11 is in a straight state. When the transmission member 31s rotates, the pressing portion 316s abuts against the first section 361r, causing the first section 361r to change, that is, the first section 361r is in a bent state or a curved state after being pressed. While the first section 361r is pressed, it drives the flexible member 36r to move rightward along the first direction, causing the triggering portion 364r to change from a relaxed state to a tight state and trigger the detection member 900. After the transmission member 31s continues to rotate, the pressing portion 316s releases the abutment on the first section 361r, and the triggering portion 364r changes to a relaxed state and releases the triggering of the detection member 900.

[0437] Embodiment 17:

[0438] Unless otherwise specified, the structure in this embodiment is the same as that in the fifteenth embodiment.

[0439] like Figures 82 to 88 As shown, the difference between this embodiment and the fifteenth embodiment is that the driving assembly and the transmission assembly are different.

[0440] like Fig.83 As shown, in this embodiment, the driving assembly includes a driving part 21, a developing gear 22, a powder feeding gear 23, a stirring gear 24, a first idler gear 25, a second idler gear 26 and a third idler gear 27. The developing gear 22 and the powder feeding gear 23 are meshed with the driving gear 212 to receive power and rotate, the first idler gear 25 is meshed with the driving gear 212 to receive power, and the first idler gear 25 transmits the power to the stirring gear 24 through the second idler gear 26 and the third idler gear 27. In this embodiment, the first idler gear 25, the second idler gear 26, the third idler gear 27 and the stirring gear 24 are all secondary gears to meet the rotation speed required by this embodiment. This embodiment does not limit the number of gears and the meshing relationship of the transmission assembly, which can be set according to actual needs.

[0441] like Figure 83 to Figure 86 As shown, the transmission assembly includes a first rotating member 31t, a second rotating member 32t (equivalent to a transmission member) and a flexible member 36r. The first rotating member 31t is located at the first end 11, and the first rotating member 31t includes a first tooth portion 311t and a first driving protrusion 312t. In the first direction, the first tooth portion 311t is farther away from the second end 12 than the first driving protrusion 312t. The first tooth portion 311t includes a missing tooth portion, and the first tooth portion 311t is used to mesh with the stirring gear 24 so that the first rotating member 31t can rotate with the stirring gear 24. When the missing tooth portion on the first tooth portion 311t is relative to the stirring gear 24, the first rotating member 31t no longer rotates with the stirring gear 24. The first driving protrusion 312t protrudes in the first direction. In this embodiment, the first driving protrusion 312t is preferably multiple, and the shapes of the multiple first driving protrusions 312t are not completely the same. In this embodiment, it is preferred that there are three first driving protrusions 312t.

[0442] like Fig.85As shown, the box body 10 is provided with a third support column 103, and the third support column 103 is preferably a cylinder extending along the third direction. The second rotating member 32t is rotatably supported by the third support column 103, and the second rotating member 32t is abutted by the first rotating member 31t and swings, and its swing axis is perpendicular to the first direction. The second rotating member 32t includes a first connecting portion 321t and an abutting protrusion 322t, and the first connecting portion 321t and the abutting protrusion 322t are respectively protrusions of the second rotating member 32t in the radial direction. When the first rotating member 31t rotates following the stirring gear 24, the first driving protrusion 312t abuts against the abutting protrusion 322t, so that the second rotating member 32t swings relative to the box body 10, and further, the abutting protrusion 322t swings toward the direction close to the developing roller 131, and the first connecting portion 321t swings toward the direction away from the developing roller 131 (clockwise swing when viewed from top to bottom). A first elastic member 33t is also provided on the developing box 1, and the first elastic member 33t is preferably a torsion spring. The first elastic member 33t contacts the second rotating member 32t, and an abutting end 331t is provided on the first elastic member 33t. An abutting block 107 protruding in the third direction is provided on the box body 10, and the abutting end 331t is abutted by the abutting block 107. When the second rotating member 32t swings, the first elastic member 33t generates elastic deformation. After the abutting protrusion 322t of the second rotating member 32t is disengaged from the abutment with the first driving protrusion 312t of the first rotating member 31t, the first elastic member 33t releases the elastic force to make the second rotating member 32t swing in the opposite direction (swing counterclockwise) to reset.

[0443] like Figure 84 to Figure 86As shown, the structure of the flexible member 36r in this embodiment is the same as that in the fifteenth embodiment, and it also directly triggers the detection member 900 as the detected member. The flexible member 36r can be made of plastic material, or metal material or resin material. This embodiment does not limit the material of the flexible member 36r, and it can complete the required function. The flexible member 36r extends in the first direction, and the flexible member 36r includes a first section 361r and a second section 363r. The end of the first section 361r is provided with a second connecting portion 362r. The second section 363r includes a triggering portion 364r and a fourth connecting portion 365r. The fourth connecting portion 365r is provided at the end of the second section 363r. The second connecting portion 362r is connected to the first connecting portion 321t of the second rotating member 32t, and can be connected by sleeve setting, welding or gluing. When the second rotating member 32t is abutted by the first rotating member 31t and swings, the flexible member 36r moves following the movement of the second rotating member 32t. A first guide rail 152t extending in the first direction is provided on the fifth end 15, and part of the flexible member 36r is located in the first guide rail 152t. The first guide rail 152t guides the flexible member 36r to move along a preset path, and the guide surface in the first guide rail 152t is preferably a smooth surface to reduce the friction between the flexible member 36r and the first guide rail 152t.

[0444] like Fig.86 As shown, the second protective cover 121 is also provided with a second guide rail 1213t and a third connecting portion 1215t. The second guide rail 1213t extends along the first direction and has a bend in the second direction. The bend is located at the left end of the second guide rail 1213t. In the second direction, the bend is located in front of the third connecting portion 1215t. Preferably, the guide rail surface in the second guide rail 1213t is a smooth surface. The third connecting portion 1215t is a protruding structure. Another part of the flexible member 36r is located in the second guide rail 1213t, so that the flexible member 36r is guided by the second guide rail 1213t to move. The bend on the second guide rail 1213t makes the second section 363r of the flexible member 36r bend and extend in the second direction, that is, it has a length in the second direction. The fourth connecting portion 365r is connected to the third connecting portion 1215t, which can be connected by sleeve connection, welding or gluing. The portion of the second section 363r between the fourth connecting portion 365r and the bend is a triggering portion 364r, which can directly trigger the detection member 900, so that the image forming device recognizes the developing cartridge 1. When the flexible member 36r moves following the swing of the second rotating member 32t, the first section 361r of the flexible member 36r moves in the second direction away from the developing roller 131, so that the flexible member 36r slides rightward relative to the box body 10 on the first guide rail 152t and the second guide rail 1213t, and the second section 363r of the flexible member 36r is pulled, and the triggering portion 364r changes from a relaxed state to a tight state.

[0445] like Fig.82 and Fig.84 As shown, a cover 150 is provided on the box body 10, and the cover 150 is used to cover part of the flexible member 36r and the second rotating member 32t, so that the flexible member 36r and the second rotating member 32t are not easily damaged or separated.

[0446] like Fig.87 and Fig.88 As shown, when the driving part 21 receives the power output by the image forming device to rotate, the first rotating member 31t receives the power and rotates, the first driving protrusion 312t abuts against the abutting protrusion 322t, so that the second rotating member 32t swings, and the first connecting part 321t connected to the first section 361r swings in the direction away from the developing roller 131, thereby causing the flexible member 36r to move and the triggering part 364r to change from a relaxed state to a tight state, thereby triggering the detection member 900, and the first elastic member 33t deforms and accumulates elastic force. When the second rotating member 32t loses the abutment of the first rotating member 31t, the first elastic member 33t releases the elastic force to make the second rotating member 32t swing in the opposite direction, and the triggering part 364r is pressed down by the detection member 900 and changes from a tight state to a relaxed state, and the flexible member 36r slides leftward in the first direction. Since a plurality of first driving protrusions 312t are provided on the first rotating member 31t, the triggering part 364r can trigger the detection member 900 multiple times. After the detection is completed, the first rotating member 31 t no longer rotates along with the stirring gear 24 .

[0447] In some embodiments, when the driving unit 21 does not receive the power output by the image forming device, the first rotating member 31t is in contact with the second rotating member 32t, the triggering unit 364r is in a tight state, and the first rotating member 31t loses contact with the second rotating member 32t after receiving the transmitted power to rotate. This embodiment does not limit the number of detection triggers and the triggering sequence, which can be set according to actual needs.

[0448] like Fig.89As shown, in order to ensure that the trigger part 364r smoothly changes from a tight state to a relaxed state, a reset component can be further provided. A third guide rail 153t and a first connecting protrusion 108 are provided on the box body 10, the third guide rail 153t extends in the first direction, and the first connecting protrusion 108 protrudes in the third direction. The reset component preferably includes a second flexible member 35t and a second elastic member 34t, the third guide rail 153t guides the movement of the second flexible member 35t, the second flexible member 35t includes a third end 351t and a fourth end 352t respectively located at both ends of the second flexible member 35t in the first direction, and the fourth end 352t is hooked with the trigger part 364r. The second elastic member 34t is preferably a tension spring, one end of the second elastic member 34t in the first direction is connected to the first connecting protrusion 108, and the other end is connected to the third end 351t, and the second elastic member 34t can be stretched and restored in the first direction. When the trigger part 364r changes from the relaxed state to the tight state, the trigger part 364r drives the second flexible member 35t to move relative to the box body 10, and the second elastic member 34t is stretched and accumulates elastic force. When the second rotating member 32t loses the abutment of the first rotating member 31t, the second elastic member 34t releases the elastic force to make the second flexible member 35t move in the opposite direction, and the second flexible member 35t drags the trigger part 364r, so that the trigger part 364r changes from the tight state to the relaxed state.

[0449] In this embodiment, the flexible member 36r receives power from the first end 11 and directly triggers the detection member 900 using the triggering portion 364r located at the second end 12, so that the structure of the developing box 1 is simplified and the production cost of the developing box 1 is controlled.

[0450] In some other embodiments, Fig.90 and Fig.91 As shown, the rotation axis of the driving part 21 may intersect with the first direction. The rotation axis of the driving part 21 is inclined relative to the first direction, and the inclination angle is 0 to 20 degrees, preferably 15 degrees in this embodiment. The driving part 21 includes a power receiving part 211 and a driving gear 212. The power receiving part 211 is used to receive the power output by the image forming device, and the driving gear 212 is used to transmit the power to the remaining gears in the transmission assembly. The driving gear 212 is a trapezoidal cylindrical shape, and preferably, the diameter of the part of the driving gear 212 away from the power receiving part 211 in the first direction is greater than the diameter close to the power receiving part 211. Correspondingly, the developing gear 22, the powder feeding gear 23 and the first idler gear 25 meshing with the driving gear 212 are all trapezoidal cylindrical shapes to ensure that the developing gear 22, the powder feeding gear 23 and the first idler gear 25 stably receive power.

The unlocking member 34u can be fixed on the second support column 109 through the fixing hole 341u and can rotate around the second support column 109, and its rotation axis is parallel to the third direction. The second unlocking protrusion 342u can abut and cooperate with the first unlocking protrusion 329u on the second driving gear 52 so that the unlocking member 34u rotates around the second support column 109. The acceleration member 35u includes an acceleration body 351u, a locking recess 352u, a fourth fixing portion 353u, and an accommodating recess 354u. The acceleration body 351u can cooperate with the second track 154u on the box body 10, and the acceleration body 351u can move left and right along the first direction in the second track 154u. When the acceleration member 35u is installed in the second track 154u, one end of the speed change elastic member 37u abuts against the left side wall of the second track 154u along the first direction, and the other end abuts against the acceleration member 35u through the accommodating recess 354u, and the locking portion 343u on the unlocking member 34u can cooperate with the locking recess 352u.

[0460] like Fig.93 , Fig.97 and Fig.98As shown, the flexible member 36u acts as a detected member to directly trigger the detection member 900, which is a whole rope-like member, including a first end 361u and a second end 362u. The first end 361u is connected to the third fixed portion 333u on the translation member 33u, and then the main body of the flexible member 36u passes through the first guide rail 151u to bypass the second end 12 and then passes through the second guide rail 153u, and then the second end 362u is connected to the fourth fixed portion 353u on the acceleration member 35u, that is, the first end 361u of the flexible member 36u is connected to the translation member 33u, and the second end 362u is connected to the acceleration member 35u, and its main body is installed in the first guide rail 151u and the second guide rail 153u, and the flexible member 36u bypassing the second end 12 is the triggering portion 363u, and is projected from top to bottom along the third direction, and the projection of the flexible member 36u is a "U" shape with the opening facing the right side.

[0461] like Fig.97 and Fig.98 As shown, the second protective cover 121 is also provided with a first correction groove 1211u, a first correction hole 1212u, and a second correction groove 1213u. The first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u are provided above the second protective cover 121 in the third direction. The second correction groove 1213u is used to fix the flexible member 36u passing through the first guide rail 151u. The flexible member 36u passing through the second correction groove 1213u passes through the first correction hole 1212u, passes through the first correction groove 1211u, and then enters the second guide rail 153u. In this embodiment, the flexible member 36u is fixed in the second correction groove 1213u. The part of the flexible member 36u between the positive groove 1213u and the first correction hole 1212u is the trigger part 363u. In this embodiment, the first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u are provided to better fix the flexible member 36u at the second end 12, and to facilitate the trigger part 363u located at the second end 12 to better play a role when the flexible member 36u is installed on the first guide rail 151u and the second guide rail 153u. In other embodiments, the first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u may not be provided, and other intermediate structures may be provided for fixing the flexible member 36u, as long as the flexible member 36u can play its corresponding role, and the specific structure is not limited too much here.

[0462] A detection member 900 is also provided in the image forming device, which includes a detection portion 910. When the developing box 1 and the drum assembly are installed in the image forming device together, the trigger portion 363u causes the detection member 900 to move, and then the image forming device receives the signal transmitted by the detection member 900, thereby identifying the developing box 1.

[0463] like Figures 98 to 102The figure shows the initial state of the developing box 1 and the drum assembly after being installed into the image forming device and cooperating with the detection member.

[0464] like Fig.98 As shown, it is the initial state of the developing box 1, at this time, the translation member 33u is installed in the first track 152u, the first end 361u of the flexible member 36u is connected to the third fixed part 333u on the translation member 33u, and the translation member 33u is in the first position in the first track 152u, that is, the translation member 33u is close to the right side in the first track 152u, that is, the translation member 33u is a certain distance from the left side of the first track 152u in the first direction, at this time, the contact part 332u of the translation member 33u and the first driving part 321u of the second rotating member 32u are in contact. The accelerating member 35u is located in the second track 154u, at this time, the second end 362u of the flexible member 36u is connected to the fourth fixed part 353u on the accelerating member 35u, at this time, the speed change elastic member 37u is located between the accelerating member 35u and the left inner wall of the second track 154u in the second direction and the speed change elastic member 37u is in a compressed state. The unlocking member 34u is in a locked position, and the locking portion 343u thereon is located in the locking recess 352u of the accelerating member 35u, that is, in the first direction, the locking portion 343u of the unlocking member 34u overlaps at least partially with the accelerating member 35u in the first direction, and a fifth fixing portion 155u is further provided on the box body 10, and the fifth fixing portion 155u at least partially overlaps with the projection of the unlocking member 34u in the third direction, and the fifth fixing portion 155u is used to further fix and limit the unlocking member 34u to prevent the unlocking member 34u from over-matching with the accelerating member 35u and difficulty in unlocking. In other embodiments, the fifth fixing portion 155u may not be provided, as long as the unlocking member 34u and the accelerating member 35u can normally match / unlock.

[0465] When the translation member 33u is in the first position, the translation member 33u will generate a first force (pulling force) F1 to the right along the first direction on the flexible member 36u located in the first guide rail 151u. At this time, the flexible member 36u that has turned through the second end will pass through the second guide rail 153u to generate a second force (pulling force) F2 to the left along the first direction on the acceleration member 35u. Since the flexible member 36u is a whole and the speed change elastic member 37u is in a compressed state, the speed change elastic member 37u will generate a third force (elastic force) F3 to the right along the first direction on the acceleration member 35u. The second force F2 and the third force F3 are coaxial and opposite in direction in the first direction, and when the translation member 33u is in the first position, the second force F2 is greater than the third force F3. At this time, there is a first distance H1 between the left end of the acceleration member 35u in the first direction and the left end of the second track 154u in the first direction.

[0466] like Fig.100As shown, when the translation member 33u is in the first position, the unlocking member 34u is in the locking position, that is, the locking portion 343u cooperates with the locking recess 352u on the acceleration member 35u, but because the second force F2 applied by the flexible member 36u to the acceleration member 35u is greater than the third force F3 applied by the speed change elastic member 37u to the acceleration member 35u, there is also a second distance H2 between the locking portion 343u and the locking recess 352u.

[0467] like Fig.101 As shown, when the translation member 33u is in the first position and the contact portion 332u thereon abuts against the first driving portion 321u on the second rotating member 32u, the developing box 1 is in the initial state. At this time, the second tooth portion 312u on the first rotating member 31u is meshed with the third tooth portion 328u on the second rotating member 32u. Specifically, looking downward along the third direction, the second tooth portion 312u is meshed with the missing tooth portion 3281u and the conical tooth portion that contacts the third tooth portion 328u when rotating counterclockwise.

[0468] like Fig.102 As shown, when the developing box 1 is in the initial state, since the translation member 33u applies a first force F1 to the right along the first direction to the flexible member 36u in the first guide rail 151u, the triggering portion 363u of the flexible member 36u at the second end 12 is in a tight state under the action of the first force F1. When the developing box 1 in the initial state is installed in the image forming device, the triggering portion 363u of the flexible member 36u will act on the detection member 900 of the image forming device, specifically, on the detection portion 910, so that the detection member 900 is in the swinging state L1. When the detection member 900 is in the swinging state L1, due to gravity or a rebound member installed therein, the detection member 900 tends to return to the non-swinging state through elastic force, and a downward pressure is exerted on the triggering portion 363u of the flexible member 36u, the triggering portion 363u.

[0469] like Fig.103As shown, when the driving gear 41 receives the drive of the image forming device, it transmits power to the first driving tooth 51 through the transmission component. When the first transmission gear 51 rotates along an axis parallel to the first direction, the second tooth portion 312u transmits power to the second rotating member 32u through the third tooth portion 328u. At this time, the second rotating member 32u rotates clockwise along an axis parallel to the third direction, that is, rotates along the rotation trajectory S1. When the second driving portion 322u is rotated to abut against the contact portion 332u, in this process, since there is no gap between the first driving portion 321u and the second driving portion 322u along the counterclockwise direction, the second rotating member 32u rotates along the rotation trajectory S2. When the rotation track S1 rotates clockwise, the translation member 33u is still in the first position, and generates the first force F1 on the flexible member 36u in the first guide rail 151u, the trigger part 363u of the second end 12 still acts on the detection part 910 of the detection member 900, the detection member 900 is still in the swinging state L1, and the second force F2 is still generated on the translation member 33u in the second guide rail 153u, and the second force F2 is greater than the third force F3, the locking part 343u and the locking recess 352u are still at the second distance H2, and the left end of the acceleration member 35u in the first direction and the left end of the second track 154u in the first direction are still at the first distance H1 unchanged.

[0470] like Figures 104 to 106 As shown, when the second rotating member 32u continues to rotate along the rotation trajectory S1 and the second driving portion 322u passes over the contact portion 332u, at this time, due to the existence of the first gap 323u, the second rotating member 32u no longer abuts against the translation member 33u, and the translation member 33u no longer applies the first force F1 to the flexible member 36u. The pressure of the detection member 900 on the trigger portion 363u causes the translation member 33u to move leftward along the first direction until the translation member 33u abuts against the inner wall of the first track 152u on the left side of the first direction, and the translation member 33u is in the second position. Under the action of gravity / rebound force, the detection member 900 swings clockwise from the swing position L1 to the non-swing position L2. At this time, since the flexible member 36u in the second guide rail 153u no longer applies the second force F2 to the acceleration member 35u, the acceleration member 35u will move to the right along the first direction by a certain distance under the action of the third force F3 applied by the speed change elastic member 37u. The distance is the same as the second distance H2. At this time, the locking recess 352u on the acceleration member 35u is in contact with the locking portion 343u on the unlocking member 34u, that is, there is no second distance H2 between the locking portion 343u and the locking recess 352u. At this time, the distance between the left side of the acceleration member 35u in the first direction and the left side of the second rail 154u is the third distance H3, and the third distance H3 is greater than the first distance H2. Specifically, the third distance H3 satisfies: H3=H1+H2, that is, the third distance H3 is equal to the sum of the first distance H1 and the second distance H2.

[0471] When the developing box 1 is in the initial state, the translation member 33u is in the first position. When it is installed in the image forming device, the detection member 900 is in the swinging position L1. When the second rotating member 32u rotates along the rotation trajectory S1 to the second driving part 322u passing over the contact part 332u of the translation member 33u, the translation member 33u moves to the second position along the first track 152u in the first gap 533. At this time, the detection member 900 is in the non-swinging position L2. The process of the detection member 900 moving from the swinging position L to the non-swinging position L2 is the image forming device completing an identification of the developing box 1. Since the models of the developing boxes 1 are different and the image forming devices are also different, after each developing box 1 is installed in the image forming device, the image forming device needs to detect the developing box 1 a different number of times, that is, the detection member 900 needs to complete a different number of swings. At the same time, different developing boxes 1 require different swinging times and swinging speeds.

[0472] like Fig.107 As shown, after the detection member 900 completes the first swinging process, the first driving tooth 51 continues to drive the second rotating member 32u to rotate along the rotation trajectory S1. When the third driving portion 324u abuts against the contact portion 332u on the translation member 33u, the translation member 33u will move leftward along the first direction in the first track 152u under the action of the third driving portion 324u, and move from the second position to the first position. At this time, the translation member 33u generates a first force F1 to the right along the first direction on the flexible member 36u, and the trigger portion 363u is straightened under the action of the first force F1, which is used to detect the detection member 900. The detecting part 910 acts so that the detecting member 900 moves from the non-swinging position L2 to the swinging position L1. At the same time, the flexible member 36u generates a second force F2 to the left along the first direction on the accelerating member 35u. The distance between the accelerating member 35u on the left side in the first direction and the second track 154u on the left side in the first direction changes from the third distance H3 to the first distance H1. The locking portion 343u on the locking member 54 and the locking recess 352u on the accelerating member 35u change from a fitted state to a second distance H2, which is exactly the same as when the developing box 1 is installed in the image forming device at the initial position.

[0473] When the second rotating member 32u continues to rotate along the rotation trajectory S1, when the third driving portion 324u passes over the contact portion 332u and the translation member 33u reaches the second gap 325u, the translation member 33u will repeat the process of moving from the first position to the second position along the first track 152u when in the first gap 323u. The state process is exactly the same and will not be described in detail here.

[0474] like Fig.108As shown, when the fourth driving part 326u passes over the translation member 33u, and the translation member 33u and the third gap 327u move from the first position to the second position, the process is exactly the same as the above process and will not be elaborated on here. At this time, the locking recess 352u on the acceleration member 35u is fitted with the locking part 343u on the unlocking member 34u, that is, there is no second distance H2 between the locking part 343u and the locking recess 352u, and the detection member 900 is in the non-swinging position L1.

[0475] like Figures 109 to 111 As shown, when the fourth driving part 326u passes over the translation member 33u, the translation member 33u and the third gap 327u move from the first position to the second position, and the second rotating member 32u continues to rotate along the rotation trajectory S1, at this time, the first unlocking protrusion 329u on the second rotating member 32u abuts against the second unlocking protrusion 342u on the unlocking member 34u, and after the unlocking member 34u receives the force transmitted by the second rotating member 32u through the second unlocking protrusion 342u, the unlocking member 34u also rotates counterclockwise around the second support column 109, and rotates until the locking recess 352u on the accelerator 35u is aligned with the locking recess 352u on the locking member 54 in the first direction. The projection of the fixed part 343u in the first direction does not overlap the unlocking position. At this time, the acceleration member 35u moves to the right along the first direction on the second track 154u under the action of the elastic force F3 of the speed change elastic member 37u. At this time, the trigger part 363u receives the action of the third force F3 and acts on the detection part 910, so that the detection member 900 moves from the non-swinging position L2 to the swinging position L1, and the speed at which the detection member 900 moves from the non-swinging position L2 to the swinging position L1 under the action of the third force F3 is greater than the speed at which the detection member 900 moves from the non-swinging position L2 to the swinging position L1 under the action of the first force F1. When the detection member 900 is in the swing position L1, the acceleration member 35u stops moving. At this time, the second rotating member 32u continues to rotate along the moving trajectory S1. When the second tooth portion 312u on the first rotating member 31u is no longer engaged with the third tooth portion 328u, that is, the second tooth portion 312u is located at the tooth-missing portion 3281u, the first rotating member 31u is disconnected from the second rotating member 32u, and the first rotating member 31u no longer transmits power to the second rotating member 32u, and the detection process of the entire developing box 1 in the image forming device is completed.

[0476] In this embodiment, the second distance H2 is smaller than the displacement in the first direction generated when the translation member 33u moves from the first position to the second position. The purpose is that, since there may be errors in the assembly process and manufacturing process of the flexible member 36u, and due to the action of the first force F1 and the second force F2, the flexible member 36u installed on the box body 10 may be elastically deformed, and the second distance H2 is used to eliminate the elastic deformation. When the translation member 33u moves from the first position to the second position, the second distance H2 is eliminated under the action of the speed-changing elastic member 37u, that is, the acceleration member 35u is moved to the right by the same distance as the second distance H2 by the action of the third force F3, that is, the flexible member 36u is pulled to the right by the length of the second distance H2. Since the second distance H2 is smaller than the displacement generated when the translation member 33u moves from the first position to the second position, when the translation member 33u is in the second position, although the acceleration member 35u pulls the flexible member 36u to the right by the length of the second distance H2, the triggering portion 363u is still in a state of no force, that is, the detection member 9 00 is still in the non-swinging position L2, but the length of the flexible member 36u remaining due to the difference between the displacement generated when the translation member 33u moves from the first position to the second position and the second distance H2 is just enough to drive the flexible member 36u to move when the translation member 55 is unlocked, so that the detection member 900 moves from the non-swinging position L2 to the swinging position L1 under the action of the third force F3. That is, the purpose of setting the second distance H2 is to prevent the flexible member 36u from becoming longer due to elastic deformation / tooling error of the flexible member 36u. When the acceleration member 35u is unlocked, it moves rightward along the first direction, and the detection member 900 moves under the action of the third force F3. However, due to the lengthening of the flexible member 36u, when the acceleration member 35u moves rightward in the first direction to the right end of the second track 154u, at this time, although the detection member 900 moves from the non-swinging position L2 under the action of the third force F3, it stops before moving to the swinging position L1, resulting in a poor last swinging effect, which affects the image forming device's recognition of the developer cartridge 1.

[0477] Furthermore, in other embodiments, the second distance H2 may not be set, as long as it can be ensured that the flexible member 36u does not produce elastic deformation during operation, or does not produce errors during production and tooling, and the flexible member 36u does not become longer during the last swing, thereby preventing the detection member 900 from reaching the swing position L1 and affecting the detection result. No specific restrictions are made here.

[0478] Furthermore, in other embodiments, the second distance H2 may not be set. It is only necessary to lengthen the length of the second track 154u in the first direction and the length of the speed change elastic member 37u so that the displacement distance of the acceleration member 35u in the first direction is sufficient to cover the elastic deformation or production and tooling errors of the flexible member 36u. No specific restrictions are made here.

[0479] Furthermore, the flexible member 36u is a whole rope-like component. In the present application, the preferred material is nylon. In other embodiments, the material may be steel wire, pure cotton, etc., which is not specifically limited here.

[0480] By providing a flexible member on the developing box 1 as a detected member, the developing box 1 can be detected more conveniently by the image forming device and has higher adjustability.

[0481] Embodiment 19:

[0482] Unless otherwise specified, the structure in this embodiment is the same as that in the first embodiment.

[0483] The difference between this embodiment and the first embodiment is that the power source of the detected component is different.

[0484] like Fig.115 As shown, a first support column 101 is provided at the first end 11, and the first support column 101 extends in a first direction away from the first end 11.

In this embodiment, the second support column 113 is preferably provided in two, and the two second support columns 113 are provided around the second opening 114. In other embodiments, the number of the second support columns 113 can be set according to actual needs.

[0485] like Fig.113 and Fig.114 As shown, the first protective cover 111 is detachably mounted on the first end 11, and the first protective cover 111 includes a first hole 1111, a second hole 1112, a third hole 1113 and a third support column 1114. The first hole 1111 and the second hole 1112 are through holes of the first protective cover 111 in the first direction, and the second hole 1112 is located behind the first hole 1111 in the second direction. The power receiving part 211 is exposed to the outside through the first hole 1111, and the third hole 1113 is a through hole of the first protective cover 111 in the third direction. The third support column 1114 extends in the first direction, and the third support column 1114 is preferably a cylinder.

[0486] like Figure 112-119As shown, the developing box 1 also includes a trigger assembly, which is preferably arranged at the first end 11, and includes a force-bearing member 71a, a limiting member 72a, and a first elastic member 73a. The force-bearing member 71a is movably supported by the first support column 101, and a force-bearing protrusion 711a extending in the first direction is provided on one end of the force-bearing member 71a away from the first end 11 along the first direction. In this embodiment, two force-bearing protrusions 711a are preferably provided, and the force-bearing protrusion 711a has an abutted surface (an inclined surface or an arc surface, preferably an arc surface in this embodiment), and the extending direction of the abutting surface intersects with the first direction. The force-bearing member 71a is at least partially located in the driving part 21, and the power receiving part 211 has a through hole penetrating in the first direction, and there are preferably two through holes, and the force-bearing protrusion 711a is exposed to the outside through the through hole, and the force-bearing protrusion 711a receives an external force and moves, that is, the force-bearing protrusion 711a is abutted by the power output member 920 of the image forming device and moves to the left relative to the box body 10 along the first direction.

[0487] like Figure 112-119 As shown, the limiting member 72a is movably supported by the first support column 101. In the first direction, the limiting member 72a is closer to the first end 11 than the force-bearing member 71a. The limiting member 72a contacts the force-bearing member 71a. When the force-bearing member 71a is subjected to force in the first direction, the limiting member 72a follows the force-bearing member 71a and moves leftward in the first direction. The limiting member 72a is provided with a limiting protrusion 721a, which protrudes radially from the limiting member 72a. The limiting protrusion 721a protrudes from the first support column 101 through the first opening 1012 on the first support column 101. The limiting protrusion 721a is provided with a first surface, which is an inclined surface or an arc surface. The first elastic member 73a is arranged in the first support column 101. The first elastic member 73a is preferably a compression spring, and can also be an elastic medium such as sponge or tension spring. Along the first direction, the first elastic member 73a is located between the limiting member 72a and the first end 11. The first elastic member 73a can be abutted and compressed by the limiting member 72a. The action force of the first elastic member 73a can make the force-bearing member 71a maintain in the position where the force-bearing protrusion 711a is exposed outside the through hole before being acted by external force, so as to facilitate the abutment of the power output member 920 therewith.

[0488] like Figures 112 to 119As shown, the developing box 1 also includes an energy storage component, which is used to apply power to the detected member 4w to trigger the detecting member 900. The energy storage component includes an energy storage rotating member 81a, an energy storage member 83a, a force applying member 82a, a translation member 85a, and a first transmission rod 84a. The energy storage rotating member 81a is rotatably supported by the first protective cover 111, and the energy storage rotating member 81a is inserted into the second hole 1112 of the first protective cover 111. In some embodiments, the energy storage rotating member 81a can be rotatably supported by the box body 10. The energy storage rotating member 81a includes a first force-bearing portion 811a, a force-applying portion 812a, and a first connecting portion 813a. The first connecting portion 813a is located between the first force-bearing portion 811a and the force-applying portion 812a along the first direction. The first force-bearing portion 811a is exposed to the outside through the second hole 1112.

[0489] like Fig.112 and Fig.117 As shown, in this embodiment, the energy storage member 83a is preferably a clockwork, and in other embodiments, it can be other energy storage components that can accumulate power. The energy storage member 83a includes a mounting portion 831a and a second connecting portion 832a, the mounting portion 831a is located at the outer periphery of the energy storage member 83a in the radial direction, the mounting portion 831a is a circular hole, the mounting portion 831a cooperates with the third support column 1114 of the first protective cover 111 so that the energy storage member 83a is supported by the first protective cover 111, and in some embodiments, the energy storage member 83a can be supported by the box body 10. The second connecting portion 832a is located inside the energy storage member 83a in the radial direction, and the second connecting portion 832a cooperates with the first connecting portion 813a so that the energy storage rotating member 81a is connected to the energy storage member 83a. When the energy storage rotating member 81a receives an external force and rotates, the energy storage rotating member 81a causes the energy storage member 83a to rotate or deform and accumulate power through the connection with the energy storage member 83a. In some embodiments, the energy storage rotating member 81 a may be formed integrally with the energy storage member 83 a .

[0490] like Figures 112 to 119As shown, the force-applying member 82a is roughly cylindrical, and the force-applying member 82a can be driven to rotate by the energy storage rotating member 81a. The force-applying member 82a is partially exposed to the outside through the third hole 1113 for easy observation. The force-applying member 82a includes a second force-bearing portion 821a, and the second force-bearing portion 821a is located at an end of the force-applying member 82a away from the first end 11 along the first direction. The second force-bearing portion 821a is provided in plurality, and the plurality of second force-bearing portions 821a are arranged in sequence along the rotation direction of the force-applying member 82a. In this embodiment, the second force-bearing portions 821a are preferably four, and the second force-bearing portion 821a is in the shape of an elastic arm, which can have a certain elastic deformation capacity. The second force-bearing portion 821a can cooperate with the force-applying portion 812a to make the force-applying member 82a rotate with the energy storage rotating member 81a (it can be known that the number of the force-applying portions 812a is not less than the number of the second force-bearing portions 821a so that the energy storage rotating member 81a drives the force-applying member 82a to rotate). The force-applying member 82a further includes a second supported portion 822a, which is preferably a cylinder extending in the first direction, and the interior of the second supported portion 822a is hollow, and a first spiral 823a is arranged therein. The force-applying member 82a further includes a limited protrusion 824a, which extends in the first direction, and is provided in a plurality of limited protrusions 824a, which are arranged at intervals along the rotation direction of the force-applying member 82a, and a second surface is provided on the limited protrusion 824a, and the second surface is an inclined surface or an arc surface. The limited protrusion 824a is limited by the limiting protrusion 721a of the limiting member 72a, so that the force-applying member 82a cannot rotate, and the second surface cooperates with the first surface to facilitate the limiting member 72a to limit and release the force-applying member 82a.

[0491] like Fig.112 As shown, the first end 11 is provided with a mounting member 86, and the mounting member 86 includes a fixing portion 861 and a supporting portion 862. In this embodiment, there are preferably two fixing portions 861, and a through hole is provided on the fixing portion 861. The fixing portion 861 cooperates with the second supporting column 113 of the first end 11, so that the mounting member 86 is installed on the box body 10. To ensure that the mounting member 86 is stably installed on the box body 10, the mounting member 86 can be further fixed by screws. In this embodiment, the supporting portion 862 is a hollow cylindrical shape, which extends along the first direction. The radius of the supporting portion 862 matches the radius of the second opening 114. The supporting portion 862 is inserted into the second opening 114. To prevent the developer in the box body 10 from leaking, a sealing member can be provided at the connection between the supporting portion 862 and the second opening 114 for sealing. The second supported portion 822a of the force-applying member 82a is inserted into the supporting portion 862 of the mounting member 86 so that the force-applying member 82a is rotatably supported by the mounting member 86.

[0492] like Fig.120 and Fig.121As shown, the second protective cover 121 is detachably mounted on the second end 12 of the box body 10, and a lifting protrusion 1216 is provided on the second protective cover 121. The lifting protrusion 1216 is preferably provided in two, and the two lifting protrusions 1216 are spaced apart along the first direction. In other embodiments, they can be provided according to actual needs. A lifting surface is provided on the lifting protrusion 1216, and the lifting surface is a slope or an arc surface, and the lifting surface extends to the left along the first direction and extends upward along the third direction.

[0493] A first supporting member 87 is detachably provided at the second end 12 . A first matching portion 871 is provided on the first supporting member 87 . The first matching portion 871 is in the shape of a guide rail extending along the third direction.

[0494] like Fig.120 and Fig.121 As shown, the first transmission rod 84a is provided with a second spiral 841a near the first end 11 along the first direction, and the other end is a butt end 842a. The second spiral 841a is supported by the support portion 862 of the mounting member 86 and cooperates with the first spiral 823a so that the first transmission rod 84a can be driven by the force member 82a to move relative to the box body 10. In this embodiment, the first transmission rod 84a preferably moves to the left along the first direction. In some embodiments, the first transmission rod 84a can rotate while moving in the first direction. The translation member 85a is provided at the second end 12, and the translation member 85a is abutted by the butt end 842a and moves in the first direction relative to the box body 10. While the translation member 85a moves in the first direction, it moves along the lifting surface of the lifting protrusion 1216 in the third direction. The translation member 85a is provided with a second matching portion 851a, and the second matching portion 851a is a protrusion extending along the first direction.

[0495] like Fig.120 and Fig.121 As shown, the detected member 4w is provided with a third matching portion 42w, a fourth matching portion 43w and a triggering portion 41w, the third matching portion 42w is in the shape of a guide rail extending in the first direction, and the third matching portion 42w is matched with the second matching portion 851a to make the detected member 4w follow the movement of the translation member 85a. The fourth matching portion 43w is in the shape of a protrusion extending along the third direction, and the fourth matching portion 43w is matched with the first matching portion 871 to make the detected member 4w move upward along the extension direction of the first matching portion 871, and the triggering portion 41w directly triggers the detection member 900. The second elastic member 36w is located at the second end 12, and the second elastic member 36w is preferably a compression spring, and can also be a tension spring or other elastic medium such as a sponge. The second elastic member 36w interacts with the detected member 4w, and the second elastic member 36w is used to make the detected member 4w move downward.

[0496] The following is the energy storage process and detection process of this embodiment:

[0497] When the energy storage assembly is installed on the box body 10, a force is applied to the first force-bearing portion 811a of the energy storage rotating member 81a so that the rotating member rotates in a clockwise direction (in this embodiment, Fig.118 (for viewing angle), the energy storage rotating member 81a rotates while driving the energy storage member 83a to deform and accumulate power. While the energy storage rotating member 81a rotates and drives the energy storage member 83a to store energy, the force-applying portion 812a interferes with the second force-bearing portion 821a, and the second force-bearing portion 821a deforms to avoid the force-applying portion 812a so that the energy storage rotating member 81a rotates smoothly in the clockwise direction. During the energy storage process, the force-applying member 82a does not rotate with the energy storage rotating member 81a or only shakes slightly. After energy storage is completed, the limiting protrusion 721a of the limiting member 72a and the limited protrusion 824a of the force-applying member 82a abut against each other, and the limiting member 72a prevents the force-applying member 82a from rotating. The end of the second force-bearing portion 821a abuts against the force-applying portion 812a to prevent the energy storage rotating member 81a from rotating counterclockwise when the energy storage member 83a releases power. That is, the limiting member can block the energy storage member 83a from releasing power to prevent the energy storage rotating member 81a from driving the force-applying member 82a to rotate counterclockwise.

[0498] like Fig.122 and Fig.123 As shown, when the developing box 1 is installed in the image forming device, before the power output member 920 is inserted into the power receiving part 211 to output power, the limiting member 72a keeps the force-applying member 82a in a limited position, and the energy storage member 83a keeps the energy storage state. When the power output member 920 is gradually inserted into the power receiving part 211 along the first direction, the power output member 920 abuts against the force-bearing protrusion 711a of the force-bearing member 71a, so that the force-bearing member 71a moves leftward along the first direction, and then the limiting member 72a moves leftward along the first direction, the first elastic member 73a is compressed, the limiting protrusion 721a moves away from the limited protrusion 824a, the limiting member 72a releases the limit on the force-applying member 82a, the energy storage member 83a is able to release power, and the energy storage rotating member 81a rotates counterclockwise under the power of the energy storage member 83a. The force-applying portion 812a abuts against the end of the second force-bearing portion 821a, so that the force-applying member 82a rotates counterclockwise along with the energy storage rotating member 81a. When the force-applying member 82a rotates, the first spiral 823a acts on the second spiral 841a, so that the first transmission rod 84a is acted on by the force-applying member 82a and moves to the left along the first direction, thereby causing the abutting end 842a of the first transmission rod 84a to abut against the translation member 85a, so that the translation member 85a moves to the left along the first direction, and moves in the third direction under the action of the lifting protrusion 1216, thereby causing the translation member 85a to drive the detected member 4w to move along the third direction, and the triggering portion 41w triggers the detection member 900.

[0499] After the detection is completed, the energy storage member 83a completely releases power, the energy storage rotating member 81a no longer drives the force applying member 82a to rotate, and the force applying member 82a no longer drives the first transmission rod 84a to move along the first direction.

[0500] This embodiment does not limit the rotation direction of the energy storage rotating member 81a and the force applying member 82a. During the detection process, the two can rotate clockwise, and during energy storage, the rotating member rotates counterclockwise to allow the energy storage member 83a to store energy.

[0501] In some embodiments, after the detection is completed, the energy storage member 83a continues to release power, but at this time the second spiral 841a moves to a position where it does not receive the drive of the first spiral 823a, and the first transmission rod 84a still may not continue to move in the first direction.

[0502] It is known that the linear movement of the force-bearing member 71a along the first direction after being abutted precedes the rotation of the driving part 21 after receiving power. In some embodiments, the movement of the force-bearing member 71a along the first direction can be performed simultaneously with the rotation of the driving part 21.

[0503] Embodiment 20:

[0504] Unless otherwise specified, the structure in this embodiment is the same as that in the nineteenth embodiment.

[0505] The difference between this embodiment and the nineteenth embodiment is that the energy storage assembly is arranged at the second end 12 .

[0506] The developing box 1 includes a trigger assembly, an energy storage assembly and a detected component 4v.

[0507] like Fig.126 and Fig.127 As shown, the trigger assembly includes a force-bearing member and a first transmission rod 72. In this embodiment, the force-bearing member and the first transmission rod 72 can be formed in one piece or in a separate combination. When the force-bearing member is abutted by the force output member, it drives the first transmission rod 72 to move leftward in the first direction to trigger the energy storage assembly. The first transmission rod 72 extends in the first direction, and a trigger protrusion 721 is fixedly provided on the left end of the first transmission rod 72. The trigger protrusion 721 extends in the radial direction of the first transmission rod 72 and protrudes from the circumferential surface of the first transmission rod 72. In other embodiments, the cross-section of the first transmission rod 72 can also be set to a rectangle or a polygon, and the trigger protrusion 721 can also extend along the second direction or the third direction.

[0508] like Fig.124 As shown, in this embodiment, the energy storage assembly is preferably arranged at the second end 12 , and the energy storage assembly includes a first support member 81 , an energy storage member 83 , a shield 82 and a locking member 84 .

[0509] like Fig.124 and Fig.125As shown, the first support member 81 is fixedly mounted on the second end 12, and the first support member 81 includes a mounting portion and a support portion 811, the mounting portion extends along the second direction and is fixedly mounted on the second end 12 by means of buckles, screws, etc., the support portion 811 and the mounting portion are fixedly arranged, and the support portion 811 and the mounting portion can be integrally formed. The support portion 811 extends leftward from the mounting portion in the first direction, and a first groove 812 is arranged on the support portion 811, the first groove 812 is circular, a second support shaft 813 is arranged at the center of the first groove 812, a socket 814 is arranged on the second support shaft 813, and a mounting hole 815 extending along the second direction is also arranged on the second support shaft 813. A first through hole 8111 is also provided on the support portion 811. The first through hole 8111 extends along the second direction. The first through hole 8111 is located at an eccentric position of the first groove 812. A locking member 84 is installed in the first through hole 8111. The locking member 84 is supported by the first through hole 8111 and can slide in the second direction relative to the first through hole 8111.

[0510] like Fig.125 and Fig.127 As shown, the detected part 4v includes a main body and a trigger part 41v, the main body is cylindrical and the main body is installed in the first groove 812, the outer circumferential surface of the main body is fitted with the inner circumferential surface of the first groove 812 and is rotatably supported by the first groove 812, and a second groove 42v that is recessed forward is also formed on the main body, and the second groove 42v is circular. A third through hole 44v is provided on the main body, and the third through hole 44v extends along the second direction. As the detected part 4v rotates, the third through hole 44v can be rotated to a position aligned with the first through hole 8111 in the second direction. The third through hole 44v is provided with a forced push inclined surface 45v at the upstream end in the rotation direction of the detected part 4v, and the inclined direction of the forced push inclined surface 45v is set to be more forward in the second direction than the downstream end at the upstream end in the rotation direction of the detected part 4v. The forced push inclined surface 45v is used to contact with the stopper 84 and apply a forced push force with a forward component force in the second direction to the stopper 84.

[0511] The trigger portion 41v is fixedly disposed on the outer circumference of the main body, and is specifically integrally formed on the outer circumference of the main body, and extends radially away from the axis of the main body. A second through hole 43v is formed on the main body for the second support shaft 813 to pass through.

[0512] The energy storage member 83 is a coil spring or a mainspring. In this embodiment, it is preferably a coil spring. One end of the coil spring is inserted into the socket 814 and fixed by the socket 814. The other end of the coil spring is fixedly connected to the inner circumference of the second groove 42v of the detected member 4v.

[0513] like Fig.125 and Fig.127As shown, the shield 82 is disc-shaped, and a mounting post 821 is provided at the front end of the shield 82. The mounting post 821 is inserted into the mounting hole 815 so that the shield 82 is fixedly mounted on the first support member 81. The shield 82 is used to cover the first groove 812 and the second groove 42v to prevent foreign objects from touching the energy storage member 83 and has a limiting effect on the energy storage member 83 and the detected member 4v, preventing the energy storage member 83 from disengaging from the second groove 42v backwards and preventing the detected member 4v from disengaging from the first groove 812 backwards.

[0514] The energy storage component has a holding state and a release state. The developing box 1 is uniformly preset in the holding state when leaving the factory. When the energy storage component is in the holding state, the energy storage member 83 produces elastic deformation and accumulates elastic potential energy. The locking member 84 is inserted into the first through hole 8111 and the third through hole 44v at the same time, and the locking member 84 is abutted by the trigger protrusion 721 to offset the forced thrust applied by the forced thrust inclined surface 45v to the locking member 84, so that the locking member 84 cannot be separated from the first through hole 8111, thereby limiting the rotational movement of the detected member 4v under the elastic force of the energy storage member 83 to keep it stationary, that is, in this embodiment, the locking member 84 acts as a limit member to limit the detected member 4v to prevent the detected member 4v from moving within an unpredictable time.

[0515] When the energy storage assembly is in the released state, the locking member 84 is out of contact with the trigger protrusion 721. Under the elastic force of the energy storage member 83, the detected member 4v is subjected to the elastic force in the circumferential direction, so that the detected member 4v applies a forced pushing force to the locking member 84 through the forced pushing inclined surface 45v, so that the locking member 84 moves forward and disengages from the third through hole 44v, and the detected member 4v is no longer limited, so that the detected member 4v can rotate under the elastic force of the energy storage member 83.

[0516] When the first transmission rod 72 follows the force-bearing member to move in the first direction, the trigger protrusion 721 moves leftward from the non-triggered position to the triggered position together with the first transmission rod 72. When the trigger protrusion 721 is in the non-triggered position, it abuts against the stop member 84 and applies a backward force to the stop member 84, so that the stop member 84 remains in the first through hole 8111 and the third through hole 44v, thereby limiting the rotation of the detected member 4v, that is, the energy storage assembly is in a holding state. When the trigger protrusion 721 moves to the trigger position, the trigger protrusion 721 disengages from the abutment with the stop member 84, and the energy storage assembly enters a released state, and the stop member 84 disengages from the third through hole 44v and no longer limits the detected member 4v.

[0517] After the energy storage component enters the release state, the detected member 4v rotates counterclockwise (viewed from the back to the front) under the elastic force of the energy storage member 83, so that the triggering part 41v makes a counterclockwise circular motion, and then contacts the detection member and drives the detection member to move, thereby triggering the detection member. In the present application, the developing box 1 can change the number of rotations of the detected member 4v or the number of triggering parts 41v by changing the degree of power storage of the energy storage member 83, and change the triggering duration and triggering speed of the triggering part 41v when the triggering part 41v triggers the detection member. By selecting energy storage members 83 of different specifications or changing the size of the triggering part 41v in the rotation direction, the triggering part 41v can be changed.

[0518] The present embodiment provides a developing box 1, which can provide a new structure that enables the developing box 1 to be detected by an image forming device. It does not need to be powered by the image forming device to operate. It only needs the image forming device to trigger the trigger member at the initial stage to operate through the power stored in the energy storage component. Compared with the prior art, the load on the power output member of the image forming device is reduced, which is beneficial to extending the life of the image forming device.

[0519] Embodiment 21:

[0520] Unless otherwise specified, the structure in this embodiment is the same as that in the nineteenth embodiment.

[0521] The difference between this embodiment and the nineteenth embodiment is that the energy storage components are different.

[0522] like Figure 128-Figure 131 As shown, the energy storage assembly in this embodiment includes an energy storage member 83a, a translation member 85a, a first transmission rod 84b, and a second transmission rod 86b. The translation member 85a is the same as that in the embodiment 20 and will not be described in detail in this embodiment.

[0523] like Figure 128-Figure 131 As shown, in this embodiment, the energy storage member 83b is preferably a torsion spring, and the energy storage member 83b is in an energy storage state when installed on the box body 10. The energy storage member 83b includes a second force applying portion 831b.

[0524] like Figure 128-Figure 131As shown, the first transmission rod 84b is provided with a limited protrusion 841b and a fourth abutting protrusion 842b, the limited protrusion 841b protrudes radially from the first transmission rod 84b, and the limited protrusion 841b is limited by the limiting protrusion 721a, so that the first transmission rod 84b cannot rotate. The fourth abutting protrusion 842b protrudes radially from the first transmission rod 84b. The energy storage member 83b is sleeved on the first transmission rod 84b, and the second force-applying portion 831b abuts against the limited protrusion 841b. The right end of the first transmission rod 84b can extend from the fourth hole of the first protective cover 111. The worker can rotate the first transmission rod 84b to make the energy storage member 83b twist and store energy when the factory preset, and then limit the first transmission rod 84b through the limiting member 72a. When the limiting member 72 a releases the restriction on the first transmission rod 84 b , the energy storage member 83 b releases power to allow the first transmission rod 84 b to rotate relative to the box body 10 .

[0525] like Fig.130 As shown, the first protective cover 111 is provided with an abutted portion 1115, which is arranged around the fourth hole, and is spirally shaped and extends in the direction close to the first end 11. The fourth abutting protrusion 842b of the first transmission rod 84b abuts against the abutted portion 1115. When the first transmission rod 84b is driven to rotate by the energy storage member 83b, the fourth abutting protrusion 842b is acted upon by the abutted portion 1115 to drive the first transmission rod 84b to move leftward along the first direction in a rotational manner.

[0526] like Fig.131 As shown, in this embodiment, a second transmission rod 86b is further provided, one end of the second transmission rod 86b is in contact with the left end of the first transmission rod 84b, and the other end is in contact with the translation member 85a. When the first transmission rod 84b moves to the left along the first direction, it drives the second transmission rod 86b to move to the left along the first direction, and the second transmission rod 86b drives the translation member 85a to move along the first direction, thereby causing the detected member 4w to move and trigger the detection member 900. That is, in this embodiment, the first transmission rod 84b only moves linearly without rotating. In some embodiments, only the first transmission rod 84b may be provided, and the first transmission rod 84b drives the translation member 85a to move.

[0527] Embodiment 22:

[0528] Unless otherwise specified, the structure in this embodiment is the same as that in the nineteenth embodiment.

[0529] The difference between this embodiment and the nineteenth embodiment is that the energy storage component and the trigger component are different.

[0530] like Fig.132 and Fig.133As shown, in this embodiment, the trigger assembly includes a force-bearing member 71a, a first limiting member 72c, and a second limiting member 73c, and the energy storage assembly includes a first transmission rod 84c, a accommodating member 87c, an energy storage member 83c, and a translation member 85a. The force-bearing member 71a and the translation member 85a are the same as those in Example 20, and are not repeated here. The first limiting member 72c is abutted by the force-bearing member 71a. When the force-bearing member 71a is forced to move along the first direction, the first limiting member 72c follows the force-bearing member 71a to move to the left in the first direction. A force-applying surface 721c is provided on one end of the first limiting member 72c away from the force-bearing member 71a along the first direction. The force-applying surface 721c is an arc surface or an inclined surface, and its extension direction intersects with the first direction and the second direction, specifically extending to the left along the first direction and extending backward along the second direction. The second limiting member 73c includes a force-bearing hole 731c and a second limiting portion 732c. The force-bearing hole 731c is connected to the first limiting member 72c. Specifically, the force-applying surface 721c is inserted into the force-bearing hole 731c. When the first limiting member 72c moves leftward along the first direction, the force-applying surface 721c is further inserted into the force-bearing hole 731c, thereby driving the second limiting member 73c to move forward along the second direction. The second limiting portion 732c is a protrusion at one end of the second limiting member 73c away from the developing roller 131 in the second direction.

[0531] like Fig.132 and Fig.133 As shown, one end of the first transmission rod 84c located at the first end 11 in the first direction is the force-bearing end, and the other end is the abutting end. The force-bearing end is provided with a third force-bearing portion 841c, a limited portion 842c and an air outlet 843c. The third force-bearing portion 841c is a hole-shaped concave along the first direction, the limited portion 842c is a groove that is concave in the radial direction of the force-bearing end, and the air outlet 843c is a through hole in the radial direction of the first transmission rod 84c. The second limiting portion 732c of the second limiting member 73c is inserted into the limited portion 842c, and the second limiting member 73c is used to limit the movement of the first transmission rod 84c, and further to limit the movement of the first transmission rod 84c in the first direction. The container 87c is a container with good sealing performance, in which gas is stored, and the force-bearing end can be movably contained in the container 87c, and the air outlet 843c is surrounded by the container 87c and communicates with the outside.

[0532] like Fig.132 and Fig.133 As shown, in this embodiment, the energy storage member 83c is preferably a compression spring, which has elastic force after deformation. One end of the energy storage member 83c close to the first end 11 along the first direction is installed in the third force-bearing portion 841c of the first transmission rod 84c, and the other end is in contact with the protective cover 111. The energy storage member 83c applies elastic force to the first transmission rod 84c so that the first transmission rod 84c can move leftward along the first direction.

[0533] After the developer cartridge 1 is assembled, the energy storage member 83c is in an energy storage state, i.e., it has elastic force, exerts a force to move along the first direction to the first transmission rod 84c, and the second limiting portion 732c is inserted into the limited portion 842c, i.e., the second limiting member 73c limits the movement of the first transmission rod 84c along the first direction. When the force-bearing member 71a moves leftward along the first direction, the first limiting member 72c drives the second limiting member 73c to move forward along the second direction, and the second limiting member 73c releases the restriction on the first transmission rod 84c, and the first transmission rod 84c moves leftward along the first direction under the action of the energy storage member 83c.

[0534] During the movement of the first transmission rod 84c to the left along the first direction, the gas in the container 87c is gradually discharged through the gas outlet 843c. In this embodiment, the speed of the first transmission rod 84c moving in the first direction is controlled by gradually discharging the gas in the container 87c during the movement of the first transmission rod 84c, so as to avoid the uncontrollable movement speed of the first transmission rod 84c under the action of the energy storage member 83c. The speed of gas discharge is determined by designing the size of the gas outlet 843c, thereby controlling the speed of movement of the first transmission rod 84c.

[0535] Embodiment 23:

[0536] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 22.

[0537] The difference between this embodiment and embodiment 22 is that the energy storage components are different.

[0538] like Fig.134 and Fig.135 As shown, the energy storage component in this embodiment includes a first support member 81d and an energy storage member 83d, and the trigger component is the same as that in Example 22, which will not be repeated here.

[0539] In this embodiment, the energy storage member 83d is a constant force spring, which always has a contraction elastic force. The energy storage member 83d includes a main body 831d and a first fixing hole 832d. The main body 831d is cylindrical, and the main body 831d always has a contraction tendency. The main body 831d is hollow inside and extends along the second direction. The first fixing hole 832d is a through hole on the end of the energy storage member 83d. The first support member 81d is used to support the energy storage member 83d. The first support member 81d is inserted into the main body 831d of the energy storage member 83d to support the energy storage member 83d. The energy storage member 61 can drive the first support member 81d to move along the first direction. The first protective cover 111 is provided with a fourth guide rail 1116, which extends along the first direction. The first support member 81d is movably supported by the fourth guide rail 1116. The first support member 81d is provided with a limited protrusion 811d, which is abutted by the second limiting portion 732c to limit the movement of the first support member 81d along the first direction, thereby limiting the contraction of the energy storage member 83d.

[0540] In order to control the main body 831d to shrink in a preset direction, a fixing member 82d is inserted into the first fixing hole 832d of the energy storage member 83d, so that the main body 831d shrinks in a direction close to the first fixing hole 832d. The first protective cover 111 is provided with a second fixing hole 1117, and the fixing member 82d is inserted into the first fixing hole 832d and the second fixing hole 1117 at the same time so that the energy storage member 83d is further supported by the first protective cover 111. In some embodiments, the second fixing hole can be provided on the box body 10.

[0541] The side surface of the main body 831d of the energy storage member 83d abuts against the first transmission rod 84d. When the second limiting portion 732c releases the limiting of the first support member 81d, the energy storage member 83d contracts, and the main body 831d drives the first support member 81d to move to the left along the first direction. The main body 831d abuts against the first transmission rod 84d, causing the first transmission rod 84d to move to the left along the first direction.

[0542] Embodiment 24:

[0543] Unless otherwise specified, the structure in this embodiment is the same as that in the nineteenth embodiment.

[0544] The difference between this embodiment and the nineteenth embodiment is that a speed control component is further provided in this embodiment.

[0545] like Figure 136-Figure 140As shown, in order to prevent the energy storage rotating member 81a from rotating too fast when the energy storage member 83a releases power, thereby causing the force-applying member 82a and the first transmission rod 84a to move too fast, affecting the detection member 4w triggering the detection member 900, a control component is provided in this embodiment to control the rotation speed of the force-applying member 82a and the energy storage rotating member 81a to control the speed of the first transmission rod 84a. The speed control component in this embodiment is preferably an escapement system, and the speed control component includes an escapement fork 301 and an escapement wheel 302.

[0546] like Figure 136-Figure 140 As shown, a support platform 86e is provided at the first end 11, and the support platform 86e is clamped on the first protective cover 111 or the box body 10 by clamping, and the support platform 86e includes a support rod 861e, and the support rod 861e is a round rod extending along the first direction. The escapement fork 301 includes a first convex portion 3011, a second convex portion 3012, a clamped portion 3013 and a hole portion 3014, and the hole portion 3014 is preferably a round hole, and the hole portion 3104 cooperates with the support rod 861e, that is, the support rod 861e is inserted into the hole portion 3014 so that the escapement fork 301 is rotatably supported by the support rod 861e. A second clamping portion 1118 is provided on the first protective cover 111, and the clamped portion 3013 is clamped by the second clamping portion 1118, and the clamped portion 3013 has a certain elasticity. The first convex portion 3011 and the second convex portion 3012 are located on the rotation path of the escape wheel 302, and the first convex portion 3011 and the second convex portion 3012 successively contact the escape wheel 302 to reduce the rotation speed of the escape wheel 302. In the radial direction, the first convex portion 3011 and the second convex portion 3012 are located on one side of the hole portion 3014, and the clamped portion 3013 is located on the other side of the hole portion 3014. When the first convex portion 3011 and the second convex portion 3012 are abutted by the escape wheel 302 to make the escapement fork 301 rotate with the hole portion 3014 as the rotation point, the clamped portion 3013 generates elastic deformation, and after the first convex portion 3011 and the second convex portion 3012 lose abutment, the elastic recovery is performed to make the escapement fork 301 rotate in the opposite direction to reset.

[0547] like Figure 136-Figure 140As shown, the escape wheel 302 is coaxial with the force applying member 82a and rotates in the same direction. The escape wheel 302 is driven by the energy storage rotating member 81a to rotate. The escape wheel 302 includes an abutting convex portion 3021 and a fourth force receiving portion 3022. The radius of the abutting convex portion 3021 is greater than the radius of the fourth force receiving portion 3022, that is, the fourth force receiving portion 3022 is located radially inside the abutting convex portion 3021. The abutting convex portion 3021 is a protrusion protruding radially relative to the escape wheel 302, and the protruding direction of the abutting convex portion 3021 intersects both the radial direction and the rotation direction. A plurality of abutting convex portions 3021 are provided, and the plurality of abutting convex portions 3021 are arranged at intervals along the rotation direction of the escape wheel 302. When the escape wheel 302 rotates, the first convex portion 3011 and the second convex portion 3012 of the pallet fork 301 abut against the abutting convex portion 3021 and elastically avoid, so as to reduce the rotation speed of the escape wheel 302 . The fourth force-bearing portion 3022 is used to be driven by the energy storage rotating member 81a so that the escape wheel 302 rotates following the energy storage rotating member 81a. There are multiple fourth force-bearing portions 3022, and the multiple fourth force-bearing portions 3022 are arranged along the rotation direction of the escape wheel 302. In this embodiment, the fourth force-bearing portion 3022 is preferably a wedge-shaped structure, which includes a force-bearing surface and a crossing surface. The force-bearing surface and the crossing surface intersect each other. When the energy storage rotating member 81a is rotating while storing energy, the force-applying portion 812a of the energy storage rotating member 81a contacts the crossing surface but does not drive the escape wheel 302 to rotate. When the energy storage rotating member 81a is released from rotation, the force-applying portion 812a abuts against the force-bearing surface, so that the escape wheel 302 rotates following the energy storage rotating member 81a. In this embodiment, the structure of the second force-bearing portion 821a of the force-applying member 82a is the same as that of the fourth force-bearing portion 3022.

[0548] In this embodiment, the energy storage rotating member 81a rotates in the counterclockwise direction (in this embodiment, Fig.139 The energy storage member 83a is used as a viewing angle to store energy. When the energy storage member 83a releases power, the rotating member rotates in the clockwise direction and drives the force-applying member 82a and the escape wheel 302 to rotate in the clockwise direction. When the escape wheel 302 rotates, the contact convex portion 3021 contacts the first convex portion 3011 and the second convex portion 3012 in sequence. The escape wheel 302 applies a swinging force to the escape fork 301. The escape fork 301 applies a reaction force to the escape wheel 302. The reaction force reduces the rotation speed of the escape wheel 302, thereby reducing the rotation speed of the energy storage rotating member 81a, and further reducing the rotation speed of the force-applying member 82a. Therefore, the speed of the first transmission rod 84a moving leftward along the first direction is reduced.

[0549] In this embodiment, the escapement fork 301 elastically avoids the escapement wheel 302 after being abutted by the escapement wheel 302, which not only reduces the rotation speed of the escapement wheel 302, but also prevents the escapement wheel 302 from being completely stuck and unable to rotate. In other embodiments, the clamped portion 3013 may not be provided, and a connecting portion may be provided on the other side of the hole portion 3014 along the radial direction. The connecting portion is connected to an elastic member. When the escapement fork 301 is abutted and rotated, the elastic member is deformed. When the escapement fork 301 loses the abutment, the elastic member elastically recovers, causing the escapement fork 301 to rotate in the opposite direction to reset.

[0550] In other embodiments, the speed control component is a hairspring type, which can also reduce the rotation speed of the energy storage rotating member 81a and thus reduce the rotation speed of the force applying member 82a and the translation speed of the first transmission rod 84a.

[0551] In some embodiments, the speed control component is grease, preferably damping oil, which has high stability and viscosity. The damping oil is applied to the first spiral 823a and the second spiral 841a, which can not only reduce the friction between the first spiral 823a and the second spiral 841a to play a protective role, but also reduce the translational speed of the first transmission rod 84a.

[0552] In other embodiments, damping oil is applied to the pallet fork 301 to slow down the rotational avoidance speed of the pallet fork 301 , thereby further slowing down the rotational speed of the escape wheel 302 .

[0553] like Fig.141 As shown, in some embodiments, the other side of the hole portion 3014 in the radial direction is a pendulum 3015. When the developing box 1 is installed in the image forming device, the pendulum 3015 swings, and after the first protrusion 3011 and the second protrusion 3012 lose abutment, the pendulum 3015 swings to reset the escapement fork 301.

[0554] Embodiment 25:

[0555] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 24.

[0556] The difference between this embodiment and embodiment twenty-four is that the structure of the speed control component in this embodiment is different, and the transmission rod directly triggers the detection member 900.

[0557] like Fig.142 and Fig.143As shown, in this embodiment, a first gear portion 825f is further provided on the force-applying member 82f, and a first gear 88f and a second gear 89f are further provided at the first end 11. The first gear 88f and the second gear 89f are rotatably supported by the box body 10, and the first gear 88f is meshed with the first gear portion 825f to rotate with the force-applying member 82f, and the second gear 89f is meshed with the first gear 88f to rotate with the first gear 88f, and the transmission rotating member 39f receives the power transmitted by the second gear 89f and rotates to drive the detected member to move.

[0558] like Fig.142 and Fig.143 As shown, in this embodiment, the speed control assembly includes a first abutted member 303 and a first deceleration elastic member 304. The first abutted member 303 is movably supported by the box body 10. The first abutted member 303 can move along the first direction relative to the box body 10. The first abutted member 303 includes a first abutted surface 3031. The first abutted surface 3031 is preferably an inclined surface or an arc surface. The extension direction of the first abutted surface 3031 intersects with the first direction. In the first direction, the first deceleration elastic member 304 is located between the first abutted member 303 and the first end 11. The first deceleration elastic member 304 can be compressed and stretched along the first direction. The first deceleration elastic member 304 provides elastic force for the first abutted member 303 to move rightward along the first direction. The first deceleration elastic member 304 and the first abutted member 303 are preferably two groups. When the force member 82f rotates, the limited projection 824a of the force member 82f abuts against the first abutted member 303, and further, the second surface (inclined surface) abuts against the first abutted surface 3031, and the first abutted member 303 is subjected to the leftward force in the first direction applied by the force member 82f, and the first abutted member 303 applies a reaction force to the force member 82f to reduce the rotation speed of the force member 82f, and the first deceleration elastic member 304 is compressed. After the force member 82f continues to rotate, the limited projection 824a passes over the first abutted member 303, and the first deceleration elastic member 304 applies an elastic force to the first abutted member 303 to make it move rightward along the first direction, so that the first abutted member 303 is abutted again by the remaining limited projections 824a.

[0559] like Fig.142 and Fig.143As shown, the speed control assembly also includes a second abutted member 305 and a second deceleration elastic member 306. The second abutted member 305 can move along the first direction relative to the box body 10. Along the first direction, the second deceleration elastic member 306 is located between the second abutted member 305 and the first protective cover 111. The second deceleration elastic member 306 can be compressed and stretched along the first direction. A second abutted surface 3051 is provided on the second abutted member 305. The second abutted surface 3051 is preferably multiple, and the multiple second abutted surfaces 3051 are arranged along the rotation direction of the second gear 89f. The second abutted surface 3051 is preferably an inclined surface or an arc surface. The extension direction of the second abutted surface 3051 intersects with the first direction and the radial direction. A third abutting surface 891f is provided on the second gear 89f. Preferably, there are multiple third abutting surfaces 891f, and the multiple third abutting surfaces 891f are arranged along the rotation direction of the second gear 89f. The third abutting surface 891f is preferably an inclined surface or an arc surface. The extension direction of the third abutting surface 891f intersects with the first direction and the radial direction. The extension direction of the third abutting surface 891f intersects with the extension direction of the second abutted surface 3051, and the two are matched. When the second gear 89f rotates, the second abutted surface 3051 abuts against the third abutting surface 891f, and the third abutting surface 891f applies a force to the second abutted surface 3051 to move rightward along the first direction, so that the second abutted member 305 moves rightward along the first direction, and the second deceleration elastic member 306 is compressed, and the second abutted member 305 applies a reaction force to the second gear 89f, which reduces the rotation speed of the second gear 89f, thereby reducing the rotation speed of the transmission rotating member 39f, thereby reducing the movement of the detected member. The second deceleration elastic member 306 releases the elastic force to make the second abutted member 305 move leftward along the first direction to apply a reaction force to the second gear 89f again. In some embodiments, only the first abutted member 303 may be provided.

[0560] It is known that in this embodiment, a flexible member or a plurality of rotating members may be used to transmit power from the first end 11 to the second end 12 .

[0561] It is known that the second abutted member 305 may act on the first gear 88f.

[0562] It is known that the second gear portion 395f of the transmission rotating member 39f may be a toothless portion to prevent the energy storage member 83a from continuing to release power after the detection is completed.

[0563] Embodiment 26:

[0564] Unless otherwise specified, the structure in this embodiment is the same as that in the nineteenth embodiment.

[0565] like Figure 144 to Figure 146As shown, the difference between this embodiment and the nineteenth embodiment is that the energy storage component is cancelled and a transmission component is provided to drive the detected component 4w.

[0566] In this embodiment, a transmission protrusion 251w protruding to the left is provided on the left end face of the first idler wheel 25w, and the transmission protrusion 251w extends in a circumferential direction around the rotation axis of the first idler wheel 25w. A transmission inclined surface 2511w is provided on the transmission protrusion 251w, and the inclination direction of the transmission inclined surface 2511w is set in the rotation direction of the first idler wheel 25w. The upstream end of the transmission inclined surface 2511w is further to the left in the first direction than the downstream end.

[0567] This embodiment also includes a transmission assembly, which includes a pipe 31w and a ball 32w.

[0568] The pipe fitting 31w is fixedly arranged on the box body 10, and the pipe fitting 31w extends in the first direction. The right end of the pipe fitting 31w is located at the first end 11, and the left end is located at the second end 12. In the present embodiment, the pipe fitting 31w is arranged on the box body 10 so as to penetrate the accommodating cavity of the box body 10 along the first direction. In other embodiments, the pipe fitting 31w may also be arranged on the outer surface of the box body 10, and the pipe fitting 31w may also be integrally formed with the box body 10, or one part of the pipe fitting 31w is integrally formed with the box body 10, and the other part is separately fixed on the box body 10, and the two parts of the pipe fitting 31w are combined into a complete pipe fitting 31w.

[0569] A notch 311w for the transmission protrusion 251w to pass through is provided on the side wall of the portion of the pipe 31w located at the first end 11, and the transmission protrusion 251w is inserted into the notch 311w from right to left and can rotate relative to the notch 311w. A plurality of mutually contacting balls 32w are sequentially arranged in the pipe 31w along the first direction from the first end 11 to the second end 12 and can slide and roll along the pipe 31w relative to the pipe 31w.

[0570] The projections of the translation member 85a, the third fitting portion 42w, and the tube 31w in the first direction overlap, so that when the ball 32w moves along the tube 31w in the first direction, it can push the translation member 85a to move leftward along the third fitting portion 42w in the first direction.

[0571] When the driving part 21 receives the power of the image forming device and rotates, the first idler wheel 25w is driven to rotate, and the transmission inclined surface 2511w on the first idler wheel 25w rotates together with the first idler wheel 25w, thereby applying a force to the left in the first direction to the ball 32w in the pipe 31w, so that the ball 32w moves to the left, and the ball 32w pushes the translation member 85a to the left along the pipe 31w and slides to the left along the third matching portion 42w. When the translation member 85a passes through the lifting protrusion 1216, it is subjected to the force provided by the lifting protrusion 1216 and moves upward along the third direction, thereby driving the detected member 4w to move upward from the non-detection position to the detection position, thereby triggering the detection member. The reset elastic member 36w causes the detected member 4w to move downward from the detection position to the non-detection position.

[0580] The motor 31v is fixedly arranged at the rear end of the first support member 81v, and the electrode output shaft passes through the first support member 81v and extends to the front end of the first support member 81v and is fixedly connected to the detected member 4v to transmit power to the detected member 4v, so that the detected member 4v rotates around the axis extending along the second direction.

[0581] The specific working process is as follows:

[0582] When the developing box is installed in the image forming device, the power output member in the image forming device starts to rotate, and the driving trigger assembly moves from the non-trigger position to the trigger position, so that the force-bearing member 71v drives the second electrical contact member 32v and the guide protrusion 321v to move to the left, so that the guide protrusion 321v contacts and electrically connects with the first electrical contact member 34v and moves from the first disconnected position to the first connected position. At this time, the motor 31v and the battery form a loop, and the battery supplies power to the motor 31v, so that the motor 31v starts to drive the detected member 4v to rotate, and the trigger part 41v on the detected member 4v drives and triggers the detection member as the detected member 4v rotates, so that the image forming device detects the developing box.

[0583] Then, as the driving part 21 receives the power provided by the power output part of the image forming device and rotates, the power of the driving part 21 is transmitted to the stirring gear 24v, causing the stirring gear 24v to rotate, and the stirring gear 24v drives the on-off protrusion 242v to rotate, so that the on-off protrusion 242v rotates to a position in contact with the on-off abutment slope 362v on the on-off abutment protrusion 361v and applies a force to the on-off abutment slope 362v, so that the on-off abutment slope 362v is subjected to the force with a left component force, and drives the fourth electrical contact 36v to move leftward from the second connecting position in contact with the third electrical contact 35v to the second disconnecting position where it is out of contact with the third electrical contact 35v and disconnects the electrical connection, thereby forming a short circuit between the motor 31v and the battery, and the battery can no longer supply power to the motor 31v. At this time, the detected part 4v stops rotating without power input, completing the detection process.

[0584] Embodiment 28:

[0585] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 26.

[0586] like Figure 150 to Figure 153 As shown, the difference between this embodiment and embodiment 26 is that the pipe fittings, balls and translation parts are eliminated.

[0587] In this embodiment, a switch assembly and an electromagnet assembly are also provided.

[0588] The electromagnet assembly includes an electromagnet 44x, a swinging member 42x, and a battery 45x. A first wire 31x is arranged between the positive electrode of the battery 45x and the positive electrode of the electromagnet 44x. One end of the first wire 31x is fixedly connected and electrically connected to the positive electrode of the battery 45x, and the other end is fixedly connected and electrically connected to the positive electrode of the electromagnet 44x. The negative electrode of the electromagnet 44x is fixedly connected and electrically connected to the second wire 32x, and the negative electrode of the battery 45x is fixedly connected and electrically connected to the third wire. The second wire 32x and the third wire extend into the accommodating bin. A wire mounting hole is arranged on the stirring frame and the stirring gear 24x, which penetrates the stirring frame and the stirring gear 24x in a first direction. The second wire 32x and the third wire are arranged in the wire mounting hole and extend along the wire mounting hole from the second end 12 to the first end 11 and extend to the right out of the wire mounting hole.

[0589] The swing member 42x is rotatably mounted on the first support member 81x and the swing member 42x swings around a rotation axis extending along the second direction. The swing member 42x is made of a material that can be magnetically adsorbed, such as metal iron. The right end of the swing member 42x is the adsorption end 421x and the left end is the contact end 422x. The swing center of the swing member 42x is located between the adsorption end 421x and the contact end 422x in the second direction. The electromagnet 44x is arranged below the adsorption end 421x of the swing member 42x. In the third direction, the swing member 42x is arranged between the detected member 4x and the electromagnet 44x, and the contact end 422x is used to contact the detected member 4x.

[0590] The on-off assembly includes a conductive sheet 33x, which is fixedly mounted on the first protective cover 111. The conductive sheet 33x includes a first on-off control portion 731x and a second on-off control portion 332x. The first on-off control portion 731x is disposed at the front end of the conductive sheet 33x, and the first on-off control portion 332x is tilted in a direction such that the front end is further to the left than the rear end. The second on-off control portion 332x is disposed at the rear end of the conductive sheet 33x, and the second on-off control portion 332x is tilted in a direction such that the front end is further to the right than the rear end.

[0591] The conductive sheet 33x is in contact with and electrically connected to the right ends of the second wire 32x and the third wire, wherein the first on-off control portion 731x is in contact with and electrically connected to the right end of the second wire 32x. The right end surface of the stirring gear 24x is provided with a first control protrusion 241x, a second control protrusion 242x, and a third control protrusion 243x protruding to the right, and the right end of the third control protrusion 243x is also provided with an extension portion 2431x extending radially in a direction away from the rotation axis of the stirring gear 24x, and the radial end of the extension portion 2431x is radially greater than the radial ends of the first control protrusion 241x and the second control protrusion 242x.

[0592] The first on-off control portion 731x is located on the moving path of the first control protrusion 241x and the second control protrusion 242x, and the second on-off control portion 332x is located on the moving path of the extension portion 2431x.

[0593] In the factory preset state, the first control protrusion 241x abuts against the first on-off control part 731x, so that the conductive sheet 33x is elastically deformed and bent, so that the conductive sheet 33x and the second wire 32x are out of contact and not electrically connected, thereby causing a short circuit between the battery 45x and the electromagnet 44x, so that the electromagnet 44x is not powered and stops working.

[0594] Then, as the stirring gear 24x rotates clockwise, the first control protrusion 241x rotates together with the stirring gear 24x and loses contact with the first on-off control part 731x. At this time, the conductive sheet 33x elastically recovers and resumes contact with the second wire 32x and is electrically connected, so that a path is formed between the battery 45x and the electromagnet 44x to supply power to the electromagnet 44x, so that the electromagnet 44x adsorbs the adsorption end 421x of the swing member 42x, so that the adsorption end 421x of the swing member 42x swings downward and the contact end 422x swings upward, thereby pushing the detected member 4x to move upward from the non-detection position to the detection position.

[0595] Then, with the rotation of the stirring gear 24x, the second control protrusion 242x abuts against the first on-off control part 731x, so that the conductive sheet 33x is elastically deformed again and breaks contact with the second wire 32x, so that the circuit between the battery 45x and the electromagnet 44x is broken again. At this time, under the elastic force of the reset elastic part 43x, the detected part 4x moves downward from the detection position to the detected position.

[0596] Then, with the rotation of the stirring gear 24x, the second control protrusion 242x is disengaged from the first on-off control part 731x, and the conductive sheet 33x elastically recovers and regains contact with the second wire 32x, so that a passage is formed between the battery 45x and the electromagnet 44x, and the electromagnet 44x again adsorbs the adsorption end 421x of the swing member 42x, so that the contact end 422x of the swing member 42x pushes the detected member 4x upward, so that the detected member 4x moves upward from the non-detection position to the detection position, thereby completing the detection process.

[0597] Then, as the stirring gear 24x rotates, the third control protrusion 243x contacts the side of the second on-off control part 332x and drives the conductive sheet 33x to rotate, so that the first on-off control part 731x rotates and leaves the moving path of the first control protrusion 241x, the second control protrusion 242x and the third control protrusion 243x, thereby preventing the electromagnet 44x from being energized again after the detection is completed, causing the detected part 4x to move again and erroneously trigger the detection part.
