In this embodiment, the meshing portion 511 is specifically a tooth group, and the meshing portion 511 is used to mesh with the first tooth portion 461 of the second gear 46 so that the first rod 51 can move with the second gear 46, specifically, the first rod 51 swings with the rotation of the second gear 46, and the swing axis (i.e., the first swing axis) of the first rod 51 extends along the third direction, and preferably the first swing axis is parallel to the rotation axis of the second gear 46, i.e., the first swing axis is parallel to the third direction. The first connection portion 512 includes a second mounting post 5121 and a first through hole 5122. The second mounting post 5121 extends along the third direction. In this embodiment, the second mounting post 5121 is preferably cylindrical and multiple, specifically four, and in other embodiments, the second mounting post 5121 may be one. The first through hole 5122 is preferably a circular hole that penetrates the first connection portion 512 along the third direction, and the first through hole 5122 is sleeved on the first mounting post 571.

[0088] The second rod 52 is provided with a second connection portion 521 at one end close to the first end 11 in the first direction, and a lifting portion 522 at one end away from the first end 11 in the first direction. The second connection portion 521 includes a second hole 5211 and a third through hole 5212. In this embodiment, the second hole 5211 is a circular hole penetrating the second connection portion 521 along the third direction, and a plurality of the second holes 5211 are provided, specifically, four of the second holes 5211 are provided in cooperation with the second mounting column 5121. The four second mounting columns 5121 are respectively inserted into the four second holes 5211 so that the second rod 52 is connected to the first rod 51, so that the second rod 52 can move with the first rod 51, and because the second mounting column 5121 extends along the third direction, the second rod 52 can move relative to the first rod 51 along the third direction. The third through hole 5212 is a circular hole penetrating the second connection portion 521 along the third direction. The third through hole 5212 is the same as the first through hole 5122, and both are sleeved on the first mounting column 571. When assembling the developing box 1, the first rod 51 is firstly mounted on the first mounting column 571, and then the second rod 52 is mounted on the first mounting column 571 to connect the first rod 51 with the second rod 52, and then the anti-slip member 572 is inserted into the first mounting column 571 to prevent the first rod 51 and the second rod 52 from being separated, and the first rod 51 and the second rod 52 are swing rods swinging around the first mounting column 571 as the swing center. The lifting portion 522 is formed by bending the second end of the second rod 52 downward along the third direction and then bending leftward along the first direction, that is, the lifting portion 522 and the second connecting portion 521 have a height difference in the third direction. The first lifting protrusion 55 and the second lifting protrusion 56 are within the swing path range of the second rod 52, that is, when the second rod 52 swings along with the first rod 51, the second rod 52 can move upward relative to the box body 10 along the extension direction of the first lifting surface 551 and the second lifting surface 561, that is, the second hole 5211 of the second rod 52 moves relative to the first rod 51 along the extension direction of the second mounting column 5121. In some embodiments, the first connecting portion 512 is provided with the second hole 5211, and the second connecting portion 5212 is provided with the second mounting column 5121, so that the second rod 52 can also slide relative to the first rod 51 in the third direction.

[0089] The detected member 54 is movably arranged at the second end 12 of the box body 10. The detected member 54 is used to trigger the detection member in the image forming device. The detected member 54 includes a detected protrusion 541, a force-bearing portion 542, and a guiding portion 543. The detected protrusion 541 is located at an end of the detected member 54 away from the second end 12 in the first direction. The detected protrusion 541 is a protrusion protruding along the first direction. The detected protrusion 541 is used to trigger the detection member. The force-bearing portion 542 is located at an end of the detected member close to the second end 12 in the first direction. The force-bearing portion 542 is concave in the first direction and extends in the second direction. The force-bearing portion 542 is used to receive the force applied by the lifting portion 522 of the second rod 52 so as to move the detected member 54. Specifically, the lifting portion 522 is inserted into the force-bearing portion 542. The force-bearing portion 542 can be a groove. In the first direction, the guide portion 543 is located between the detected protrusion 541 and the force-bearing portion 542 . The guide portion 543 is used to guide the movement direction of the detected member when the detected member 54 moves. The guide portion 543 includes a guide protrusion 5431 , which protrudes along the second direction relative to the detected member 54 .

[0090] The detected member 54 is made of a conductive material such as metal or conductive resin, and can contact the electrical terminal in the image forming device, that is, the detected member 54 in this embodiment can be regarded as an electrode, which is used to receive the electric energy output by the image forming device, and directly or indirectly transfer the electric energy to the developing roller 131 and the powder feeding roller, so that the developing roller 131 and the powder feeding roller are charged to absorb the developer. In some embodiments, the detected member 54 can also be an insulating material. In some embodiments, the detected member and the electrode can be separately provided, and in other embodiments, the detected member 54 can be located at the first end 11 of the box body 10.

[0091] like Figure 5 , Figure 8 and Fig. 9As shown, the developing box 1 is further provided with a guide member 53, which is located at the second end 12 and is used to guide the movement of the detected member 54. The guide member 53 includes an upper plate 531, a mounting protrusion 532, a first guide groove 533 and a second guide groove 534. The upper plate 531 is located at one end of the guide member 53 close to the fifth end 15 in the third direction. The upper plate 531 at least covers a portion of the detected member 54. The mounting protrusion 532 protrudes downward along the third direction on the basis of the upper plate 531. The first guide groove 533 and the second guide groove 534 both extend along the third direction. The guide portion 543 cooperates with the first guide groove 533 and moves along the extension direction of the first guide groove 533. The guide protrusion 5431 cooperates with the second guide groove 534 and moves along the extension direction of the second guide groove 534. The guide groove includes the first guide groove 533 and / or the second guide groove 534. In some embodiments, the guide groove may also be provided on the detected member 54 , and the guide protrusion 5431 may be provided on the guide member 53 , which can also guide the detected member 54 to move along the third direction.

[0092] The second end 12 of the box body is also provided with a first elastic member 58, and the first elastic member 58 is used for resetting the detected member in the third direction. In this embodiment, the first elastic member 58 is preferably a compression spring, and the first elastic member 58 can be compressed and stretched along the third direction. One end of the first elastic member 58 in the third direction is sleeved on the mounting protrusion 532, and the other end is abutted against the detected member 54.

[0093] The following is the working process of the detected component in this embodiment:

[0094] See also Fig.10 When the power receiving portion 40 does not receive the power output by the image forming device, the first rod 51 and the second rod 52 are both in a stationary state, the meshing portion 511 of the first rod 51 meshes with the first tooth portion 461 of the second gear 46, and the lifting portion 522 of the second rod 52 is closer to the developing roller 131 than the first lifting protrusion 55 and the second lifting protrusion 56 in the second direction, and the lifting portion 522 is inserted into the force-bearing portion 542 of the detected member 54.

[0095] When the power receiving portion 40 starts to receive the power output by the image forming device, when viewed from the first end 11 of the developing cartridge from right to left, the power receiving portion 40 moves along the Figure 3 The first gear 45 rotates in the clockwise direction as shown in the figure, and transmits power to the stirring gear 44, the first gear 45 and the second gear 46 in sequence. The stirring gear 44 rotates in the counterclockwise direction, the first gear 45 rotates in the clockwise direction, and when looking down from the fifth end 15 of the developing box, the second gear 46 rotates in the counterclockwise direction, see Figure 10 to Figure 11, the first rod 51 swings following the rotation of the second gear 46, the meshing portion 511 of the first rod 51 swings in the second direction toward the developing roller 131, and the second rod 52 swings following the first rod, that is, the lifting portion 522 swings in the direction away from the developing roller 131. When the second rod 52 swings to the first lifting protrusion 55, the second rod 52 moves along the extension direction of the first lifting surface 561, and drives the detected member 54 to move upward along the third direction through the lifting portion 522, so that the detected protrusion 541 triggers the detection member for the first time, and the first elastic member 58 is compressed and accumulates elastic potential energy. As the first rod 51 continues to mesh with the second gear 46 and rotates, the second rod 52 continues to swing following the first rod 51, and the second rod 52 is separated from the first lifting protrusion 55. Under the action of the first elastic member 58, the detected member 54 and the second rod 52 fall, and the second rod 52 is located in the gap between the first lifting protrusion 55 and the second lifting protrusion 56. In some embodiments, the first elastic member 58 may not be provided, and the second rod 52 and the detected member 54 fall automatically.

[0096] See also Fig.12 As the first rod 51 continues to mesh with the second gear 46 and rotates, the second rod 52 continues to swing following the first rod 51, and the second rod 52 moves to the second lifting protrusion 56 and moves along the second lifting surface 561, so that the second rod 52 drives the detected member 54 to move upward again, so that the detected protrusion 541 triggers the detection member for the second time, and the second rod 52 continues to swing and then disengages from the second lifting protrusion 56, and the second rod 52 and the detected member 54 fall down. After the detection is completed, the meshing portion 511 of the first rod 51 is disengaged from the second gear 46, and the first rod 51 no longer swings following the rotation of the second gear 46, and the second rod 52 also no longer swings, and the lifting portion 522 is farther away from the developing roller 131 than the second lifting protrusion 56 in the second direction.

[0097] In this embodiment, two transmission rods, the first rod 51 and the second rod 52, are provided to ensure the meshing and transmission effect between the first rod 51 and the second gear 46, and also ensure the movement effect of the second rod 52 in the third direction. It is known that in some embodiments, only one transmission rod may be provided instead of two transmission rods, the first rod and the second rod, and the transmission rod slides as a whole in the third direction, as long as the first tooth portion 461 of the second gear 46 is extended in the third direction, so that the transmission rod meshes with the first tooth portion 461 and swings while being able to move in the third direction.

[0098] It is known that in other embodiments, the detected member may not be provided separately, and the detected protrusion is directly formed at the second end of the transmission rod, which moves upward to trigger the detection member of the image forming device.

[0099] In some embodiments, the lifting protrusion is not provided with a lifting surface, and the second end of the transmission rod, that is, the second end of the second rod 52, is provided with a lifting surface at the position where the first lifting protrusion 55 cooperates. The lifting surface extends backward along the second direction and extends upward along the third direction, and the second rod 52 can also move upward along the first lifting protrusion 55 and the second lifting protrusion 56 and drive the detected member 54 to move upward along the third direction. Of course, the lifting protrusion and the second end of the second rod 52 can both be provided with a lifting surface. The first lifting protrusion 55 and the second lifting protrusion 56 can also be arranged in the middle of the box body or close to the first end 11 in the first direction.

[0100] The first gear part is a specific implementation of the first transmission part, the second gear part is a specific implementation of the second transmission part, the first tooth part is a specific implementation of the force application part, and the second gear 46 is a specific implementation of the transmission member. In some embodiments, the first transmission member is a protrusion structure protruding from the outer periphery of the first gear 45, and the second transmission member is provided with a matching part that cooperates with the protrusion structure. When the first gear 45 rotates around the rotation axis extending along the first direction, the protrusion structure on the first gear 45 abuts against the matching part of the second gear 46, so that the second gear 46 rotates, and the second gear 46 drives the first rod 51 to swing. Further, the first end of the first rod 51 is not provided with a meshing part, and the protrusion structure is provided on the outer periphery of the transmission member, that is, the second gear 46 is not provided with the first tooth part 461, and the transmission member may not be the second gear. When the transmission member rotates around the rotation axis extending along the third direction, the protrusion structure on the outer periphery of the transmission member as the force application part abuts against the first end of the first rod 51 and drives the first rod 51 to swing. In some embodiments, the first transmission part can also drive the second transmission part to rotate by friction when the first gear 45 rotates, thereby driving the transmission member to rotate. When the transmission member rotates, the force applying part can also drive the first end of the first rod 51 to rotate by friction.

[0101] In this embodiment, a lifting protrusion is provided, so that when the second rod 52 abuts against the lifting protrusion, the second rod 52 can move in the third direction, thereby realizing that the developing box is detected by the detection member of the image forming device. In some embodiments, the lifting protrusion may not be provided, and when the second rod 52 swings, the second end of the second rod 52 directly triggers the detection member, so that the detection member rotates, so that the second end of the second rod 52 is identified, that is, the developing box is identified. In this embodiment, by providing multiple lifting protrusions, the second rod 52 abuts against the lifting protrusions multiple times, so that the developing box is detected multiple times. In some embodiments, the developing box is not provided with a lifting protrusion, and multiple detected protrusions are formed at the second end of the transmission rod. When the second rod 52 swings, the multiple detected protrusions trigger the detection member in sequence, which can also realize that the second rod is identified.

[0102] The first gear 45 of this embodiment is meshed with the stirring gear, so that the space arrangement of the first end 11 of the developing box is reasonable. In some embodiments, the first gear 45 can also be directly meshed with the driving gear.

[0103] It should be noted that, in this embodiment, the detected member 54 is separately provided from the transmission unit, and the second end of the transmission unit is indirectly detected by the detection member of the image forming device through the detected member 54, which also belongs to "the second end of the transmission unit is detected by the detection member of the image forming device". In other embodiments, the detected member 54 may also be directly provided as one body with the transmission unit, that is, the detected member 54 is directly formed at the second end of the transmission unit, and the second end of the transmission unit is directly detected by the detection member of the image forming device.

[0104] This embodiment realizes transmission of the transmission unit through a first gear 45 whose rotation axis extends along a first direction and a second gear 46 (transmission member) whose rotation axis extends along a third direction, so that the developing box can be better detected by the image forming device, thereby improving the operating stability of the developing box.

[0105] Embodiment 2:

[0106] If there is no special explanation, the structure of this embodiment is the same as that of the first embodiment. The difference between this embodiment and the first embodiment lies in the different specific structure of the connection between the first rod and the second rod.

[0107] like Fig.13 and Fig.14As shown, in this embodiment, the end of the first rod 51 close to the first end 11 in the first direction is still provided with a meshing portion 511, and the meshing portion 511 meshes with the second gear 46 to receive power to make the first rod swing. The end of the first rod 51 far from the first end 11 in the first direction is provided with a first connecting portion 512. In this embodiment, the first connecting portion 512 is a groove that is recessed in the third direction and extends along the first direction, and its opening faces upward. A first through hole (not shown) that penetrates the first connecting portion 512 along the third direction is provided in the first connecting portion 512. In the first direction, the first connecting portion 512 is closer to the first end 11 than the first lifting protrusion 55. The end of the second rod 52 close to the first end 11 in the first direction is provided with a second connecting portion 521. The second connecting portion 521 is specifically a second hole that penetrates the second rod 52 along the third direction. The first mounting column 571 is inserted into the first through hole and the second hole so that the first rod 51 and the second rod 52 are mounted on the box body 10. A lifting portion 522 is provided at one end of the second rod 52 away from the first end 11 in the first direction, and the lifting portion 522 is used to move the detected member 54. The second rod 52 is at least partially located in the groove of the first rod 51, and the front wall and the rear wall of the groove in the second direction limit the second rod 52 so that the second rod 52 can swing with the first rod 51, and the second rod 52 can move relative to the first rod 51 along the extension direction of the first mounting column 571.

[0108] This embodiment also provides a variant implementation:

[0109] Unless otherwise specified, the structure in this variant embodiment is the same as that in Example 2. In the above schemes of Example 1 and Example 2, the second rod is configured to swing with the first rod around the first swing axis (specifically extending along the third direction, preferably parallel to the third direction), and can slide relative to the first rod in the third direction. In this variant embodiment, the second rod is still configured to swing with the first rod around the first swing axis, but the second rod cannot slide relative to the first rod in the third direction, but can swing relative to the first rod around the second swing axis (specifically extending along the second direction, preferably parallel to the second direction), and the swing is realized in that the second end of the second rod converts the swing around the first swing axis into the swing around the second swing axis by interacting with the lifting protrusion, thereby realizing movement in the third direction.

[0110] In this variant embodiment, the second rod 52 is no longer restricted by the first mounting column 571 and the anti-slip member 572. The first rod 51 and the second rod 52 are matched with each other in an axial-hole manner. The first connecting portion 512 of the first rod 51 is provided with a mounting hole, which is a through hole or a blind hole, preferably a through hole, and preferably a round hole. The second connecting portion 521 of the second rod 52 is provided with a connecting shaft extending in the second direction, the connecting shaft is inserted into the through hole, the connecting shaft is the swing center, and the connecting shaft is preferably circular. When the second rod 52 interferes with the lifting protrusion, the second rod 52 not only follows the first rod 51 to continue to swing along the swing axis parallel to the third direction, but also the end of the second rod 52 close to the lifting portion 522 swings relative to the first rod 51 around the swing axis extending in the second direction, that is, the lifting portion 522 swings upward and drives the detected member 54 to move upward. In some embodiments, the connecting shaft can also be provided on the first connecting portion 512, and the mounting hole can also be provided on the second connecting portion 521.

[0111] Embodiment three:

[0112] Unless otherwise specified, the structure of this embodiment is the same as that of the first embodiment. The difference between this embodiment and the first embodiment is that the structure of the transmission assembly in this embodiment is different, the first lifting surface 551 and the second lifting surface 561 are arranged in different directions, and the swing directions of the first rod 51 and the second rod 52 are different during detection. In the first embodiment, the transmission member is a second gear, the second gear 46 rotates with the rotation of the first gear 45, and the rotation axis of the second gear 46 extends along the third direction. In this embodiment, the transmission member is a rack group, the rack group moves with the rotation of the first gear 45, and the movement axis of the rack group extends along the second direction. In Embodiment 1, during detection, the first end of the first rod swings in the second direction from a position close to the fourth end of the box body to a position close to the third end of the box body (i.e., swings from back to front), and the second end of the second rod swings in the second direction from a position close to the third end of the box body to a position close to the fourth end of the box body (i.e., swings from front to back). In this embodiment, during detection, the first end of the first rod swings from a position close to the third end of the box body to a position close to the fourth end of the box body (i.e., swings from front to back), and the second end of the second rod swings from a position close to the fourth end of the box body to a position close to the third end of the box body (i.e., swings from back to front).

[0113] like Fig.15 - Fig. 20As shown, in this embodiment, the transmission assembly includes a driving part 4, a developing gear 41, a powder feeding gear 42, a stirring gear 44, a first gear 45 and a transmission member (including a first toothed portion and a second toothed portion). In this embodiment, the transmission member is specifically implemented as a rack set 72, the first toothed portion is specifically implemented as a first rack portion 721, and the second toothed portion is specifically implemented as a second rack portion 722. The first gear 45 includes a first gear portion 451 and a second gear portion 452. In the first direction, the first gear portion 451 is farther away from the first end 11 than the second gear portion 452. The first gear portion 451 is meshed with the stirring gear 44 so that the first gear 45 receives the power transmitted by the stirring gear 44 and rotates. The rack assembly 72 includes a first rack portion 721 (i.e., a first toothed portion), a second rack portion 722 (i.e., a second toothed portion) and a main body portion 723. The main body portion 723 is block-shaped. The first rack portion 721 and the second rack portion 722 are both arranged on the main body portion 723 and are located at both ends of the main body portion 723 in the third direction. In the third direction, the first rack portion 721 is at least partially located above the second rack portion 722. The second rack portion 722 is located to the right of the first rack portion 721 in the first direction. The first rack portion 721 and the second rack portion 722 both have a plurality of teeth arranged in the second direction. The second rack portion 722 meshes with the second gear portion 452 of the first gear 45 to receive the power transmitted by the first gear 45 and move approximately in the second direction relative to the box body 10. The first rack portion 721 meshes with the meshing portion 511 of the first rod 51 so that the first rod 51 swings following the movement of the rack assembly 72. The second rod 52 swings following the swing of the first rod 51 .

[0114] The fifth end 15 of the box body 10 is provided with a first lifting protrusion 55 and a second lifting protrusion 56. The first lifting protrusion 55 and the second lifting protrusion 56 are arranged along the second direction and the first lifting protrusion 55 is farther away from the developing roller 131 than the second lifting protrusion 56. The first lifting protrusion 55 has a first lifting surface 551, and the second lifting protrusion 56 has a second lifting surface 561. The extension directions of the first lifting surface 551 and the second lifting surface 561 are both intersecting with the second direction and the third direction. The first lifting surface 551 and the second lifting surface 561 both extend forward along the second direction and extend upward along the third direction.

[0115] See also Fig.18 When the power receiving portion 40 does not receive the power output by the image forming device, the second rack portion 722 meshes with the second gear portion 452, and the meshing portion 511 meshes with the first rack portion 721. Fig.19 When the power receiving unit 40 starts to receive the power applied by the image forming device and moves along Fig.16, and transmits power to the stirring gear 44, the first gear 45 and the rack group 72, so that the stirring gear 44 rotates in the counterclockwise direction, the first gear 45 rotates in the clockwise direction, the rack group 72 moves in the second direction away from the developing roller 131, the first rod 51 swings following the first rack portion 721, the meshing portion 511 swings in the direction away from the developing roller 131, and the lifting portion 522 of the second rod 52 swings in the direction close to the developing roller 131.

[0116] The detection process is similar to that in the first embodiment. When the second rod 52 swings to the first lifting protrusion 55, the second rod 52 moves upward along the extension direction of the first lifting surface 551, so that the detected member 54 triggers the detection member for the first time. Fig. 20 When the second rod 52 swings to the second lifting protrusion 56, the second rod 52 moves upward along the extension direction of the second lifting surface 561, so that the detected member 54 triggers the detection member for the second time. After the detection is completed, the second rack portion 722 of the rack assembly 72 is out of contact with the second gear portion 452 of the first gear, that is, the rack assembly 72 no longer receives power to move.

[0117] The first rack portion 721 is a specific implementation of the force-applying portion, and the second rack portion 722 is a specific implementation of the second transmission portion. In some embodiments, the first transmission portion is a protruding structure protruding from the outer periphery of the first gear 45, and the second transmission portion is provided with a matching portion that cooperates with the protruding structure. When the first gear 45 rotates around the rotation axis extending along the first direction, the protruding structure on the first gear 45 abuts against the matching portion of the transmission member and drives the transmission member to move along the moving axis extending along the second direction. The force-applying portion of the transmission member is a protruding structure, and the first end of the first rod 51 is provided with a matching portion that cooperates with the protruding structure of the transmission member. When the moving axis extending along the second direction of the transmission member moves, the force-applying portion on the transmission member cooperates with the matching portion of the first end of the first rod, and drives the first end of the first rod 51 to rotate around the first swing axis extending along the third direction, so that the second rod 52 also rotates around the first swing axis. It can be understood that the present embodiment may also not be provided with a lifting protrusion, and the second end of the second rod directly triggers the detection member. In some embodiments, the rack set 72 can be directly engaged with the stirring gear to receive power.

[0118] This embodiment realizes transmission of the transmission unit through the first gear 45 whose rotation axis extends in the first direction and the rack group 72 (transmission member) whose movement axis extends in the second direction, so that the developing box can be better detected by the image forming device, thereby improving the operating stability of the developing box.

[0119] Embodiment 4:

[0120] If there is no special explanation, the structure of this embodiment is the same as that of the third embodiment. The difference between this embodiment and the third embodiment is that the transmission assembly in this embodiment is different, and no transmission member is provided in the transmission assembly.

[0121] like Fig.21 - Fig. 22 As shown, the transmission assembly includes a driving part 4, a developing gear 41, a powder feeding gear 42, a stirring gear 44 and a first gear 45, the first gear 45 includes a first gear part 451 and a second gear part 452, the first gear part 451 is farther away from the first end 11 than the second gear part 452 in the first direction, the first gear part 451 is meshed with the stirring gear 44 to receive power to rotate the first gear 45, and its rotation axis is parallel to the first direction. The outer diameter of the second gear part 452 is larger than the outer diameter of the first gear part 451, and the outer diameter of the second gear part 452 can also be smaller than the outer diameter of the first gear part 451.

[0122] The end of the first rod 51 located near the first end 11 is a meshing portion 511, which is in the shape of a rack. The meshing portion 511 is matched with the second gear portion 452 of the first gear 45, and the meshing portion 511 meshes with the second gear portion 452 of the first gear 45 so that the first rod 51 moves following the rotation of the first gear 45. When the meshing portion 511 meshes with the second gear portion 452, the meshing portion 511 is specifically located above the second gear portion 452 in the third direction. The end of the first rod 51 closer to the second end 12 than the meshing portion 511 in the first direction is a first connecting portion 761 (the same as in the third embodiment, which will not be repeated here).

[0123] When the power receiving unit 40 receives the power output by the image forming device and transmits the power to the transmission assembly, the first gear 45 receives the power and moves along the Fig. 22 , the meshing portion 511 of the first lever 51 meshes with the second gear portion 452 to cause the first lever 51 to swing, the meshing portion 511 swings backward in a direction away from the developing roller 131, and the second lever 52 swings forward following the swing of the first lever 51. The detection process is the same as that of the third embodiment, and will not be repeated here. In some embodiments, the first gear 45 may be a stirring gear.

[0124] Embodiment five:

[0125] This embodiment is generally the same as the embodiment, and the main difference is that: in the embodiment one, the second end of the transmission rod (specifically the second end of the second rod) converts the swing around the first swing axis into the movement of the second end of the transmission rod itself (specifically the second end of the second rod) in the third direction by interacting with the lifting protrusion, while in the present embodiment, the second end of the transmission rod itself does not move in the third direction (the transmission rod only swings), but the detected part moves in the third direction through the action part at its end interacting with the lifting protrusion on the detected part.

[0126] In addition, in this embodiment, the first separating member is the driving part 4, and in other embodiments, the first separating member may also be disposed on the first protective cover 111. Fig. 27 As shown, the box body 10 is further provided with a third mounting column 129 extending along a third direction, and the third mounting column 129 is used to rotatably support the second gear 46 .

[0127] like Fig.25 and Fig.26 As shown, the second protective cover 121 is detachably mounted on the second end 12 of the box body 10, and the second protective cover 121 includes a guide portion 1211a and a second forced pushing member 1211, and the guide portion 1211a is two guide rails extending along the third direction. The second forced pushing member 1211 is used to receive the forced pushing force applied by the image forming device so that the developing roller 131 is in close contact with the photosensitive drum. The first protective cover 111 is also provided with a first forced pushing portion (not shown). In the second direction, the first forced pushing member and the second forced pushing member 1211 are arranged close to the fourth end 14 and protrude outward relative to the fourth end 14.

[0128] like Fig.25 , Fig. 27 , Fig.28 and Fig.30 As shown, the detected component is used to trigger the detection member 101 of the image forming device, so that the image forming device detects the information of the developing box 1 (such as different models, different capacities, newness, etc.). The transmission unit includes a transmission rod 65, which is movably mounted on the box body 10, and the transmission rod 65 includes an engaging portion 511, a lifting portion 522 and a mounting hole 513a.

[0129] The meshing portion 511 is located at one end of the transmission rod 65 close to the first end 11 in the first direction. The meshing portion 511 is a group of teeth arranged along the width direction of the transmission rod 65. The meshing portion 511 meshes with the first tooth portion 461 of the second gear 46 so that the transmission rod 65 receives the power transmitted by the second gear 46 and follows the movement of the second gear 46.

[0130] The lifting portion 522 is located at the other end of the transmission rod 65 in the first direction, that is, the second end of the transmission rod 65. The lifting portion 522 is close to the second end 12. The lifting portion 522 is a protrusion formed by bending the transmission rod 65 along the third direction and then bending and extending along the first direction. An active surface 5131 is provided on the lifting portion 522. The active surface 5131 is an inclined surface, an arc surface or an end surface. In this embodiment, it is preferably an inclined surface. The extension direction of the active surface 5131 intersects the second direction and the third direction. The active surface 5131 extends forward along the second direction and extends upward along the third direction.

[0131] In the first direction, the mounting hole 513a is located between the meshing portion 511 and the lifting portion 522. The mounting hole 513a is a through hole or a blind hole. In the present embodiment, it is preferably a circular through hole. A first mounting column 571 protruding along the third direction is provided on the box body 10. The first mounting column 571 is matched to be a cylinder. The first mounting column 571 is inserted into the mounting hole 513a so that the transmission rod 65 can be movably mounted on the box body 10 and swing relative to the box body 10 with the first mounting column 571 as the swing center. Specifically, the meshing portion 511 receives the power transmitted by the second gear 46 and swings in the direction close to the developing roller 131, and the lifting portion 522 swings in the direction away from the developing roller 131.

[0132] The first mounting column 571 is also provided with a fixing hole 1171. The developing box 1 also includes a fixing member 531 and an elastic member 532. The fixing member 531 is inserted into the fixing hole 1171 and limits the transmission rod 65 in the third direction to prevent the transmission rod 65 from being disengaged. Further, a thread can be provided in the fixing hole 1171. The fixing member 531 is a screw. The two are connected by threaded matching, or the two are fixed by interference fitting. This embodiment is not limited to this. It can prevent the transmission rod 65 from being disengaged from the box body 10. The elastic member 532 limits the transmission rod 65 in the third direction. The second elastic member 532 is an elastic medium such as a compression spring or sponge. The elastic member 532 can be deformed by the contact between the transmission rod 65 and the fixing member 531. The second elastic member 532 is used to reset the transmission rod 65 (described in detail below). In some embodiments, the second elastic member 532 may not be provided.

[0133] The detected member 54 is used to directly trigger the detection member 101. The detected member 54 is driven by the transmission rod 65 to move. The detected member 54 includes a guided portion 523, a detected protrusion 541 and at least one lifting protrusion. The detected member 54 is movably mounted on the second protective cover 121. The guided portion 523 is mounted on the guide portion 1211a of the second protective cover 121 and can slide along the extension direction of the guide portion 1211a (specifically, the third direction). The guided portion 523 is limited by the guide portion 1211a in the second direction, and is located between the detected protrusion 541 and the first lifting protrusion 55 in the first direction. In this embodiment, two lifting protrusions are provided, namely, a first lifting protrusion 55 and a second lifting protrusion 56. The first lifting protrusion 55 and the second lifting protrusion 56 are arranged along the second direction. In the second direction, the first lifting protrusion 55 is closer to the developing roller 131 than the second lifting protrusion 56. The first lifting protrusion 55 and the second lifting protrusion 56 are located on the swing path of the lifting portion 522 of the transmission rod 65. The first lifting protrusion 55 includes a first lifting surface 551, which extends forward along the second direction and extends upward along the third direction. The second lifting protrusion 512 includes a second lifting surface 561 , the second lifting surface 561 extends forward along the second direction and extends upward along the third direction, the first lifting surface 551 and the second lifting surface 561 can be inclined surfaces or curved surfaces or end surfaces, in this embodiment, in order to make the detected member 54 driven by the transmission rod 65 more smoothly, the first lifting surface 551 and the second lifting surface 561 are matched with the action surface 5131 and are set as inclined surfaces, and the extension directions of the three are preferably parallel, and the first lifting surface 551 and the second lifting surface 561 are sequentially received by the abutment of the action surface 5131 so that the detected member 54 is driven by the transmission rod 65 and moves relative to the box body 10. In another embodiment, the first lifting surface 551 and the second lifting surface 561 are specifically curved surfaces, and the extension direction of the curved surfaces is matched with the swing arc of the lifting portion 522. The detected protrusion 541 protrudes along the first direction, and the detected protrusion 541 is used to trigger the detection member 101 so that the developing box 1 is detected by the image forming device. In other embodiments, the lifting protrusions may also be provided on the second protective cover 121 or the box body 10. This embodiment does not limit the number and shape of the lifting protrusions, which may be provided according to actual needs.

[0134] The detected member 54 can be made of a conductive material such as metal or conductive resin, and is in contact with an electrical terminal in the image forming device, that is, in this embodiment, the detected member 54 can be regarded as an electrode, which is used to receive the electrical energy output by the image forming device and directly or indirectly transfer the electrical energy to the developing roller 131 and the powder feeding roller, so that the developing roller 131 and the powder feeding roller are charged to absorb the developer. In some embodiments, the detected member and the electrode can be separately provided, and in other embodiments, the detected member 54 can be located at the first end 11 of the box body 10.

[0135] The following is the working process of the detected component in this embodiment:

[0136] like Fig.31 -33, when the power receiving portion 40 does not receive the power output by the image forming device, the transmission rod 65 is in a stationary state, the meshing portion 511 of the transmission rod 65 meshes with the first tooth portion 461 of the second gear 46, and the lifting portion 522 of the transmission rod 65 contacts the first lifting protrusion 55 but does not apply force to it, and in the second direction, the lifting portion 522 is closer to the developing roller 131 than the meshing portion 511.

[0137] When the power receiving part 40 starts to receive power and transmits the power to each gear of the transmission assembly, the second gear 46 starts to move along the Fig.31 , the transmission rod 65 swings along with the rotation of the second gear 46, and the lifting portion 522 swings backward along the swinging direction away from the developing roller 131. The lifting portion 522 applies force to the first lifting protrusion 55 by contacting the first lifting surface 551 through the action surface 5131. Since the guided portion 523 is limited by the guide portion 1211a of the second protective cover 121 in the second direction, the detected member 54 moves upward along the third direction, and the detected protrusion 541 touches the detecting member 101 for the first time. After the transmission rod 65 continues to swing, the first lifting protrusion 55 is separated from the lifting portion 522 and enters the gap between the first lifting protrusion 55 and the second lifting protrusion 56, and the detected member 54 moves downward in the third direction. When the lifting portion 522 swings to the second lifting protrusion 56, the lifting portion 522 contacts the second lifting protrusion 56, so that the detected member 54 moves upward again to trigger the detecting member 101 for the second time. After the transmission rod 65 continues to swing, the meshing portion 511 is disengaged from the first tooth portion 461 of the second gear 46, the transmission rod 65 no longer follows the movement of the second gear 46, the lifting portion 522 is disengaged from the second lifting protrusion 56, the detected member 54 moves downward, and the detection is completed. In the second direction, the lifting portion 522 is farther away from the developing roller than the meshing portion 511. In some embodiments, in order to prevent the detected member 54 from being separated from the second protective cover 121 when moving upward along the third direction, a stopper may be added; in order to prevent the detected member 54 from being unable to move downward by its own weight after moving upward, a first elastic member 58 may be added. When the detected member 54 moves upward, the first elastic member 58 accumulates elastic potential energy, and after the lifting protrusion is separated from the lifting portion 522, the first elastic member releases the elastic potential energy to make the detected member 54 move downward.

[0138] When the detected component needs to be reset for the next detection, the transmission rod 65 is lifted upward so that the second elastic member 532 is compressed or further compressed, and the transmission rod 65 is reversed, that is, the meshing portion 511 rotates in a direction away from the developing roller 131 and meshes with the first tooth portion 461.

[0139] It is known that in other embodiments, the detected member may not be provided separately, and the detected protrusion 541 is directly formed at the second end 12 of the transmission rod, and moves upward to trigger the detection member 101 of the image forming device. In some embodiments, when the lifting portion 522 is provided with the action surface 5131, the first lifting protrusion 55 and the second lifting protrusion 56 may not be provided with a lifting surface, that is, one of the lifting portion 522 and the lifting protrusion is provided with a surface extending forward along the second direction and extending upward along the third direction, and the action surface 5131 is also a kind of lifting surface.

[0140] In some embodiments, the arrangement may be as in the third embodiment. When the first end of the transmission rod 65 receives the power of the transmission assembly, the first end of the transmission rod 65 is arranged to move in the second direction away from the developing roller 131, and the second end of the transmission rod is arranged to move in the second direction toward the developing roller. At this time, the lifting surface is arranged to extend backward along the second direction and upward along the third direction, so that the movement of the detected component 54 in the third direction can be achieved.

[0141] Embodiment six:

[0142] If there is no special explanation, the structure in this embodiment is the same as that in the first embodiment. The difference between this embodiment and the first embodiment is that the structure of the transmission assembly in this embodiment is different, and the structure of the detected assembly is different. In the first embodiment, the force-applying part of the transmission member is the first tooth part. In the present embodiment, the force-applying part of the transmission member is a cam structure. In the first embodiment, the transmission unit includes a transmission rod. In the present embodiment, the transmission unit includes not only the transmission rod but also a sliding member located at the second end of the transmission rod, and the sliding member acts as the second end of the transmission unit: in the first embodiment, the first end of the transmission rod is configured to receive the power of the transmission assembly so that the transmission rod swings relative to the box body around the first swing axis, and the second end of the transmission rod converts the swing around the first swing axis into the movement of the detected protrusion in the third direction by acting with the lifting protrusion. In the present embodiment, the first end of the transmission rod is configured to receive the power of the force-applying part of the transmission member so that the transmission rod slides relative to the box body in the first direction (rather than swinging), and the second end of the transmission rod pushes the sliding member to slide in the first direction. The sliding member converts the sliding in the first direction into the movement in the third direction by acting with the lifting protrusion, and drives the detected member to move in the third direction.

[0143] like Fig.34 - Fig.36As shown, the transmission member in this embodiment is specifically implemented as a rotating member 64, and the rotating member 64 includes a force-applying portion 641 and a second tooth portion. In this embodiment, the second tooth portion is specifically implemented as a bevel tooth portion 642. The force-applying portion 641 is a cam structure, which is cam-shaped, and is provided with a force-applying surface 6411. The force-applying surface 6411 can be an inclined surface or an arc surface, and is preferably an arc surface in this embodiment. The bevel tooth portion 642 is matched with the second gear portion 452 of the first gear 45 so that the bevel tooth portion 642 meshes with the second gear portion 452, thereby causing the rotating member 64 to receive the power transmitted by the stirring gear 44 and rotate, and its rotation axis is perpendicular to the first direction.

[0144] like Fig.35 As shown, the second protective cover 121 is located at the second end 12 of the box body 10, and the second protective cover 121 at least covers a part of the detected component. The second protective cover 121 is used to protect the detected component. The second protective cover 121 is provided with a first lifting protrusion 55 and a second lifting protrusion 56. The first lifting protrusion 55 and the second lifting protrusion 56 are arranged along the first direction and the second lifting protrusion 56 is farther away from the first end 11 than the first lifting protrusion 55. The first lifting protrusion 55 is provided with a first lifting surface 551, and the second lifting protrusion 56 is provided with a second lifting surface 561. The extension directions of the first lifting surface 551 and the second lifting surface 561 are both intersecting with the first direction and the third direction. The first lifting surface 551 and the second lifting surface 561 both extend to the left along the first direction and extend upward along the third direction.

[0145] like Fig.35 , Fig.37 and Fig.38 As shown, the detected component includes a transmission rod 65, a sliding member 66 and a detected member 54. A mounting groove 60 extending along a first direction is provided on the box body 10. The transmission rod 65 can be movably installed in the mounting groove 60. The transmission rod 65 extends along the first direction, wherein the end close to the first end 11 in the first direction is a force-bearing end 651, and the end away from the first end 11 in the first direction is a force-applying end 652. The force-bearing end 651 is abutted by the force-applying surface 6411 of the rotating member 64, so that the transmission rod 65 moves along the first direction.

[0146] See also Fig.37 and Fig.38 The sliding member 66 includes a joint portion 661, a contact portion 662 and a force plate 663. The joint portion 661 is located at one end of the sliding member 66 close to the developing roller 131 in the second direction. The contact portion 662 has an inclined surface. The extending direction of the inclined surface of the contact portion 662 intersects the first direction and the third direction. The inclined surface of the contact portion 662 is matched with the first lifting surface 551 and the second lifting surface 561. The force plate 663 is a plate-shaped member, which is used to be abutted by the force-applying end 652 of the transmission rod 65, so that the sliding member 66 moves.

[0147] The detected member 54 includes a detected protrusion 541, a guide portion 543 and a force-bearing portion 542. The detected protrusion 541 protrudes along a first direction. The detected protrusion 541 is used to trigger a detection member in the image forming device so that the developing box 1 is detected by the image forming device. The guide portion 543 is used to guide the movement direction of the detected member when the detected member 54 moves. The force-bearing portion 542 is in the shape of a groove extending along the first direction. The engaging portion 661 of the sliding member 66 is located in the force-bearing portion 542 and can move along the extension direction of the force-bearing portion 542, so that the sliding member 66 cannot drive the detected member 54 to move in the first direction. The force-bearing portion 542 surrounds the engaging portion 661 in the third direction, so that the sliding member 66 can drive the detected member 54 to move in the third direction.

[0148] like Fig.39 As shown, after the power receiving part 40 starts to receive the power output by the image forming device, the rotating member 64 starts to rotate counterclockwise, and the force-applying surface 6411 abuts against the force-bearing end 651 of the transmission rod 65, so that the transmission rod 65 gradually moves to the left along the first direction, and the force-applying end 652 of the transmission rod 65 abuts against the force-bearing plate 663 of the sliding member 66, so that the sliding member 66 moves to the left along the first direction toward the direction away from the second end 12, and the first lifting protrusion 55 and the second lifting protrusion 56 are on the movement path of the sliding member 66, that is, during the interaction of the sliding member 66, the contact portion 662 of the sliding member 66 first contacts the first lifting surface 551 of the first lifting protrusion 55 and moves along the extension direction of the first lifting surface 551, so that the engaging portion 661 of the sliding member 66 drives the detected member 54 to move upward when moving in the force-bearing portion 542 of the detected member 54, thereby causing the detected protrusion 541 to trigger the detection member in the image forming device for the first time. When the sliding member 66 moves to the gap between the first lifting protrusion 55 and the second lifting protrusion 56, the sliding member 66 and the detected member 54 move downward. When the sliding member 66 moves to the second lifting protrusion 56, the contact portion 662 contacts the second lifting surface 561 of the second lifting protrusion 56 and moves along the extension direction of the second lifting surface 561. The sliding member 66 drives the detected member 54 to move upward and causes the detected protrusion 541 to trigger the detection member for the second time. When the detection is completed, the transmission rod 65 moves to the left in the first direction to a position where the force application surface 6411 cannot contact, the rotating member 64 continues to rotate with the first gear 45, the transmission rod 65 no longer moves in the first direction, and the sliding member 66 and the detected member 54 no longer move.

[0149] It is known that the contact portion 662 may not be provided with an inclined surface, as long as the first lifting protrusion 55 is provided with a first lifting surface 551 and the second lifting protrusion 56 is provided with a second lifting surface 561, the contact portion 662 can also move along the extension direction of the first lifting surface 551 and the second lifting surface 561. It is also possible to only provide an inclined surface on the contact portion 662 without providing a lifting surface on the first lifting protrusion 55 and the second lifting protrusion 56, and the contact portion 662 can also move leftward and upward. It is known that the detected member 54, the sliding member 66 and the transmission rod 65 can also be made into an integral structure, as long as the transmission rod 65 moves to the left along the first direction, the contact portion 662 can also move upward along the first lifting protrusion 55 and the second lifting protrusion 56 in the third direction, and the transmission rod 65 can also move upward relative to the mounting groove 60.

[0150] The rotating member 64 is a specific implementation of the transmission member. In some embodiments, when the transmission member moves along the moving axis extending along the second direction, it drives the transmission rod to slide along the first direction. Specifically, the transmission member is provided with a force-applying portion 641, and the bevel tooth portion 642 of the transmission member is replaced by the second tooth portion 722 in the third embodiment. The second tooth portion 722 is meshed with the second gear portion 452 of the first gear 45. When the first gear 45 rotates, the transmission member is driven to move along the moving axis extending along the second direction through the second gear portion 452 and the second tooth portion 722, so that the force-applying portion of the transmission member abuts against the force-bearing end 651 of the first end of the transmission rod 65, and drives the transmission rod 65 to slide along the first direction. The second transmission portion and the first transmission portion may also not be meshed, and the two are set to be protrusion-matched. When the first gear rotates, the first gear drives the transmission member to move along the moving axis extending along the second direction through the first transmission portion and the second transmission portion of the transmission member. In this embodiment, the sliding member 696 and the transmission rod 65 are separate structures. In some embodiments, the sliding member 66 and the transmission rod 65 can also be an integrated structure, and the sliding member is formed at the second end of the transmission rod.

[0151] Embodiment seven:

[0152] If there is no special explanation, the structure of this embodiment is the same as that of the sixth embodiment. The difference between this embodiment and the sixth embodiment is that the structure of the rotating member in this embodiment is different.

[0153] like Fig.40 - Fig.42As shown, the rotating member 64 is rotatably supported by the third mounting column 129, and the rotating member 64 includes a force-applying portion 641 and a second tooth portion 462, and the second tooth portion 462 is specifically implemented as a bevel tooth portion. The force-applying portion 641 is a cam structure, which is cam-shaped. The force-applying portion 641 includes a starting end 6611 and an end 6612, and extends radially outward in a spiral shape from the starting end 611 to the end 6612, that is, the radial distance of the starting end 6611 is less than the radial distance of the end 6612. A force-applying surface 6411 is formed between the end 6612 and the starting end 6611, that is, on the side of the cam structure, and the force-applying surface 6411 is an arc surface, and in some embodiments, it can also be an inclined surface. The second tooth portion 462 is matched with the second gear portion 452 of the first gear 45 so that the second tooth portion 462 meshes with the second gear portion 452, so that the rotating member 64 receives the power transmitted by the first gear 45 and rotates, and its rotation axis is perpendicular to the first direction. The mounting groove 60 includes a first limiting portion 1281 and a second limiting portion 1282, which are used to prevent the transmission rod 65 from being disengaged. The second end 12 is also provided with a first elastic member 58, which is used to reset the detected member 54.

[0154] See also Fig.43 When the power receiving portion 40 does not receive the power output by the image forming device, the second tooth portion 462 is meshed with the second gear portion 452, and the force-applying surface 6411 contacts the force-bearing end 651 of the transmission rod 651 near the starting end 6611 but does not apply force to the transmission rod 65 to cause the transmission rod 65 to move.

[0155] See also Fig.44 After the power receiving unit 40 starts to receive the power output by the image forming device, the rotating member 64 starts to rotate following the first gear 45 (from Fig.44 As the rotating member 64 rotates counterclockwise), the force-applying surface 6411 rotates to abut against the force-receiving end 651, that is, the force-receiving end 651 gradually abuts from the force-applying surface 6411 close to the starting end 6611 to the force-applying surface 6411 close to the end 6612, so that the transmission rod 65 moves leftward along the second direction during the rotation of the rotating member 64.

[0156] The force-applying end 652 of the transmission rod 65 abuts against the force-bearing plate 623 of the sliding member 66, so that the sliding member 66 moves in the first direction toward the direction away from the second end 12, and the first lifting protrusion 55 and the second lifting protrusion 56 are on the movement path of the sliding member 66, that is, when the sliding member 66 slides in the first direction, the contact portion 662 of the sliding member 66 first contacts the first lifting surface 551 of the first lifting protrusion 55 and moves along the extension direction of the first lifting surface 551, so that the engaging portion 661 of the sliding member 66 moves in the force-bearing portion 542 of the detected member 54, driving the detected member 54 to move upward, thereby causing the detected protrusion 541 to trigger the detection member in the image forming device for the first time. When the sliding member 66 moves into the gap between the first lifting protrusion 55 and the second lifting protrusion 56, the sliding member 66 and the detected member 54 move downward. When the sliding member 66 moves to the second lifting protrusion 56, the contact portion 662 contacts the second lifting surface 561 of the second lifting protrusion 56 and moves along the extension direction of the second lifting surface 561. The sliding member 66 drives the detected member 54 to move upward and causes the detected protrusion 541 to trigger the detection member for the second time. Fig.45 At the end of the detection, the transmission rod 65 moves leftward in the first direction until the force-applying surface 6411 is located at the end 6612, the transmission rod 65 is no longer abutted by the force-applying surface 6411, the rotating member 64 continues to rotate with the first gear 45, the transmission rod 65 no longer moves in the first direction, and the sliding member 66 and the detected member 54 no longer move.

[0157] The above are only some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, or the above technical solutions can be freely combined, including the technical features between the above different embodiments, which all belong to the protection scope of the present invention.
