Description

Technical Field

[0001] The utility model relates to the field of electronic photographic imaging, in particular to a developing box which is detachably installed in an electronic photographic imaging device. Background Art

[0002] A developer cartridge is a container containing developer, which includes a rotatably mounted stirring element for stirring the developer. When the developer cartridge is installed in an electrophotographic imaging device (hereinafter referred to as an "imaging device"), the developer creates a desired image or text on an imaging medium using electrostatic imaging technology. To enable the device to obtain information such as the developer cartridge model, existing developer cartridges are equipped with a detection device that interacts with a detection element in the device.

[0058] It should be understood that the various embodiments described below are not isolated from each other, and those skilled in the art may combine the structures of the following embodiments with each other according to design requirements.

[0059] Example 1

[0060] [Overall structure of the developer cartridge]

[0061] like Figure 1A 、 Figure 1B and Figure 1C As shown, the developer box 1 includes a shell 2 forming a developer chamber 10 and a rotating member 3 rotatably arranged in the shell 2. The rotating member 3 can be, for example, a developing member 31 for conveying the developer outward, or a powder feeding member 32 arranged adjacent to the developing member 31 and conveying the developer to the developing member 31, or a stirring member 33 located in the developer chamber 10. The stirring member 33 stirs the developer in the developer chamber 10, which can prevent the developer from clumping on the one hand and convey the developer toward the powder feeding member 32 on the other hand; the developer box also includes a handle 23 connected to the shell 2. Along the installation direction, the developing member 31 and the handle 23 are respectively located at both ends of the shell 2.

[0062] The developing member 31 rotates about a first axis L1, and the housing 2 extends along a first direction parallel to the first axis L1. The developing cartridge 1 further has a second direction perpendicular to the first direction and a third direction perpendicular to both the first and second directions. One end 51 of the first direction points to the left of the developing cartridge, the other end 52 of the first direction points to the right of the developing cartridge, one end 53 of the second direction points to the front of the developing cartridge, the other end 54 of the second direction points to the rear of the developing cartridge, one end 55 of the third direction points upward of the developing cartridge, and the other end 56 of the third direction points downward of the developing cartridge.

[0063] Hereinafter, the left end of the developer cartridge is referred to as the driving end, and the right end is referred to as the conductive end. The detected member 9 in the device is disposed to the right of the developer cartridge, and thus the right end of the developer cartridge may also be referred to as the detecting end. The developer cartridge 1 further includes a detecting device 6 having a portion located at the driving end, another portion located at the detecting end, and a portion located between the driving end and the detecting end. The driving force transmission assembly 4 is configured to transmit the driving force received by the driving force receiving member 41 disposed at the driving end to the rotating member 3 and the detecting device 6.

[0064] The housing 2 has a left surface 21 facing the left and a right surface 22 facing the right. The developing cartridge further includes a left end cover 27 and a right end cover 28 respectively combined with the housing 2, wherein the left end cover 27 is opposite to the left surface 21, and the right end cover 28 is opposite to the right surface 22. A portion of the driving force receiving member 41 is exposed outward from the left end cover, and a portion of the detection device 6 is exposed outward from the right end cover 28. Figure 1B As shown, the right end cover 28 has an exposure opening 281, the size of which is larger than the size of the component of the detection device 6 located at the detection end (the functional component 63 described below); further, the developing box 1 also includes a developer regulating member 29 fixedly mounted on the shell 2, a conductive member 26 combined with the shell 2, and a chip assembly 11 mounted on one of the shell 2, the left end cover 27 and the right end cover 28. The chip assembly 11 can be a chip that is simultaneously provided with a substrate, electrical contacts and a storage part, or it can be a movable part having a substrate, electrical contacts, a storage part and a movable part that can be movably connected to the electrical contacts. The chip assembly 11 is used to establish a communication connection with the imaging device.

[0065] The conductive member 26 is located at the detection end and includes a main body 26a and a power input portion 26b provided on the main body 26a. The main body 26a or the power input portion 26b is fixedly connected to the housing 2. The power input portion 26b is used to receive power from the device and supply it to the developing member 31.

[0066] The developer regulating member 29 includes a blade holder 291 and a blade 292. The blade holder 291 is fixedly mounted on the housing 2. The blade 292 is fixed to the blade holder 291 and is used to contact the developer 31 to adjust the thickness of the developer on the surface of the developer 31. The blade holder 291 includes a first portion 2911 and a second portion 2912 connected to each other. The blade 292 is fixed to the second portion 2912. A bent portion 2913 is formed between the first portion 2911 and the second portion 2912, which can enhance the strength of the blade holder 291. Figure 3G As shown, when observed along the first direction, the bending portion 2913 is located outside the projection range of the driving force receiving member 41, or in other words, the projection of the driving force receiving member 41 does not pass through the bending portion 2913. Such a setting is conducive to reducing the impact of the vibration generated when the driving force receiving member 41 rotates on the bending portion 2913, so that the developer regulating member 29 can be more stable during the development / working process of the developing box 1.

[0067] In some embodiments, along the first direction, the projection of the intermediate gear 46 described below does not pass through the bending portion 2913 , which can further reduce the vibration effect on the developer regulating member 29 .

[0068] In some embodiments, the first portion 2911 can also be omitted, that is, the blade holder 291 is no longer provided with the first portion 2911, and accordingly, the bending portion 2913 no longer exists. At this time, the structure of the developer regulating member 29 can be simplified, and the blade holder 291 as a whole is no longer "L"-shaped, but "I"-shaped, and the blade 292 is still fixed on the blade holder 291, and the blade holder 291 can still be fixed on the shell 2; further, in order to strengthen the strength of the blade holder 291, a reinforcement member that extends continuously or is intermittently arranged along the first square can also be provided on the blade holder 291.

[0069] When the developing cartridge 1 is working, the developing member 31 needs to be opposite to the photosensitive drum outside the developing cartridge so that the developer carried on the surface of the developing member 31 can reach / be supplied to the surface of the photosensitive drum to realize development. For this purpose, it is more advantageous for the developing cartridge 1 to be pushed toward the photosensitive drum. Figure 1C and Figure 2 As shown, the developing box 1 also includes at least one of a first forced pushing portion 2b1 and a second forced pushing portion 2b2 arranged at the rear of the developing box, and the first forced pushing portion 2b1 and the second forced pushing portion 2b2 are used to receive the forced pushing force from the outside of the developing box, thereby forcing the developing member 31 and the photosensitive drum to maintain contact, wherein the first forced pushing portion 2b1 is located on the left side of the shell 2, and the second forced pushing portion 2b2 is located on the right side of the shell 2. Specifically, the first forced pushing portion 2b1 is formed to protrude to the left from the left direction of the shell 2, and the second forced pushing portion 2b2 protrudes to the left from the right end cover 28. That is to say, along the first direction, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 both protrude in the same direction. Therefore, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 can also both protrude to the right. This structure is conducive to the miniaturization of the developing box 1.

[0070] In some embodiments, the developing box 1 is further provided with a conductive bracket for supporting the conductive member 26, and the conductive bracket is fixedly connected to the shell 2, and the second forced pushing portion 2b2 can also be provided on the conductive bracket.

[0071] [Right end cap]

[0072] like Figure 1BAs shown, in the second direction, the right end cap 28 is located behind the conductive member 26. A portion 282 of the right end cap 28 forms a second forced-pushing portion 2b2, and a portion of the active component is exposed through the exposed opening 281. When viewed in the first direction, the right end cap 28 does not overlap with the powder filling port 2a3 located at the detection end. When the developer in the developer cartridge is depleted, the user can refill the developer cartridge without removing the right end cap 28. In the third direction, the powder filling port 2a3 is located below the active component 63. With the protruding active component, when the user refills the developer cartridge, there is no interference with the active component 63. The active component 63 and the powder filling port 2a3 can be seen simultaneously by the user, significantly reducing the risk of damage to the active component 63. In the first direction, the powder filling port 2a3 is located between the second forced-pushing portion 2b2 / 282 and the conductive member 26.

[0073] [Paper Guide]

[0074] When the developing box 1 is working, the imaging medium (such as printing paper) will pass through the developing box along the second direction from the bottom of the developing box 1 along the third direction. In order to keep the moving path of the imaging medium stable, the developing box 1 further includes a paper guide 2d provided under the shell 2. Figure 1C As shown, the paper guide 2d has a continuous surface extending basically along the first direction and the second direction. Preferably, the surface of the paper guide 2d is a smooth surface. More preferably, along the first direction, the surface of the paper guide 2d is a plane, and along the second direction, the surface of the paper guide 2d is a plurality of adjacent planes, and every two adjacent planes intersect at a line parallel to the first direction.

[0075] like Figure 1C As shown, the developer box 1 further includes a reinforcing rib 10f extending downward from the shell 2, and the paper guide 2d covers the reinforcing rib 10f. The reinforcing rib 10f covered by the paper guide 2d is less likely to be broken.

[0076] The paper guide 2d and the housing 2 can be connected by bonding, snapping, or welding.

[0077]

Drive force transmission components

[0078] like Figure 2As shown, the driving force transmission component 4 includes at least one of a driving force receiving member 41, a developing member driving member 42, a powder feeding member driving member 43 and a stirring member driving member 44. The developing member driving member 42 is coaxially arranged with the developing member 31, and is used to transmit the driving force from the driving force receiving member 41 to the developing member 31. The powder feeding member driving member 43 is coaxially arranged with the powder feeding member 32, and is used to transmit the driving force from the driving force receiving member 41 to the powder feeding member 32. The stirring member driving member 44 is coaxially arranged with the stirring member 33, and is used to transmit the driving force from the driving force receiving member 41 to the stirring member 33. When the stirring member driving member 44 is provided, the driving force transmission component 4 also includes a position between the driving force receiving member 41 and the detection device 6. The idler wheel 45 between the driving force receiving member 41 transmits the driving force to the stirring member driving member 44 through the idler wheel 45, and then the stirring member driving member 44 transmits the driving force to the detection device 6. In some embodiments, the driving force delivered to the detection device 6 can also come directly from any one of the driving force receiving member 41, the developing member driving member 42, the powder feeding member driving member 43 and the idler wheel 45; it is feasible that the stirring member 33 can be configured to rotate around an axis parallel to the first direction, or to reciprocate in a direction substantially parallel to the second direction; the driving force transmission method between the various driving members can be gear meshing transmission, belt transmission, friction wheel transmission, etc. Preferably, each driving member is configured as a gear;

[0079] The driving force receiving member 41 rotates around a second axis L2 parallel to the first direction, and the detected member 9 is configured as a rod that can rotate around a third axis L3 parallel to the first direction, including a rotating part 93 and a first rod 91 and a second rod 92 connected to the rotating part 93, wherein the second rod 92 is used to interact with the detection device 6, and the first rod 91 is used to be detected by the equipment.

[0080] In some embodiments, the powder feeding member driving member 43 is shielded by the left end cover 27 and is not exposed. At this time, the powder feeding member driving member 43 is located between the housing 2 and the left end cover 27 and is protected.

[0081]

Detection device

[0082] like Figure 2As shown, the detection device 6 includes a driving component 61 arranged at the driving end, an acting component 63 arranged at the detection end, and a transmission member 62 located between the driving component 61 and the acting component 63. After receiving the driving force, the driving component 61 drives the transmission member 62 to move in a direction that is not perpendicular to the first direction, thereby forcing the acting component 63 to interact with the detected member 9. Preferably, the movement direction of the transmission member 62 is parallel to the first direction. More preferably, the transmission member 62 reciprocates in a direction parallel to the first direction. In this way, the detection end of the developing box does not need to be provided with components such as gears and ratchets for transmitting driving force, or the number of components such as gears and ratchets for transmitting driving force is reduced. The structure of the detection end is simplified, and when the developing box is assembled, it is only necessary to focus on the assembly of the driving end.

[0083] [Drive components]

[0084] The driving assembly 61 includes a driving member 612 and a counting member 613. The counting member 613 rotates around a fourth axis L4 parallel to the first direction, and at least a portion of the counting member 613 is closer to the housing 2 than the driving member 612. The driving member 612 is used to engage with the stirring member driving member 44 and receive the driving force. Along the first direction, at least a portion of the counting member 613 is closer to the housing 2 than the stirring member driving member 44. Figure 4A and Figure 4B As shown, along the first direction, at least the portion of the counting member 613 used to interact with the transmission member 62 (such as the protrusion described below) is closer to the shell 2 / left surface 21 / right surface 22 than the driving member 612 and / or the stirring member driving member 44. Preferably, the counting member 613 as a whole is closer to the shell 2 / left surface 21 / right surface 22 than the driving member 612 and / or the stirring member driving member 44; further, along the first direction, at least a portion of the counting member 613 is closer to the shell 2 / left surface 21 / right surface 22 than the idler wheel 45 / driving force receiving member 41. In this way, the size of the developing box 1 in the first direction can be reduced, which is conducive to the miniaturization of the developing box 1.

[0085] [Drive force cutoff of drive unit]

[0086] The counting member 613 and the driving member 612 may be formed integrally or separately. After the detection is completed, the counting member 613 is prevented from moving and remains stationary by a separation mechanism provided in the developing cartridge 1. Specifically, when the counting member 613 and the driving member 612 are formed integrally, after the detection is completed, the counting member 613 as a whole will no longer receive the driving force. For example, the counting member 613 may be forced to move in a first direction as a whole, or the counting member 613 may be moved in a translational manner as a whole, so that the counting member 613 is separated from the driving source (any one of the driving force receiving member 41, the developing member driving member 42, the powder feeding member driving member 43, the stirring member driving member 44 and the idler wheel 45). Disengagement; in the case where the counting member 613 and the driving member 612 are formed as separate bodies, after the detection is completed, the counting member 613 and the driving member 612 may be disengaged, but the driving member 612 may not be disengaged from the driving source, or the counting member 613 and the driving member 612 may be disengaged from the driving source as a whole; in some embodiments, regardless of whether the counting member 613 and the driving member 612 are formed as one piece, the driving member 612 may also be configured as a gear with a toothless portion. During the detection process, the gear portion of the driving member 612 is opposite to the driving source and receives the driving force. When the detection is completed, the toothless portion of the driving member 612 is opposite to the driving source and does not receive the driving force. The toothless portion is a separation mechanism.

[0087] The counting member 613 includes a chassis 613a, a coupling portion 613b, a driving force receiving portion 613c and a plurality of protrusions arranged on the chassis 613a. The counting member 613 and the driving member 612 are coupled to each other through the coupling portion 613b. The driving force of the driving member 612 is transmitted to the counting member 613 through the coupling of the driving force output portion 6122 arranged on the driving member 612 and the driving force receiving portion 613c arranged on the counting member 613.

[0088] When observed along the rotation axis L4, the counting piece 613 is circular, and its radius R can vary between 5.0mm-7.0mm, and the optimal range is 5.5mm-6.5mm. Especially in the structure where multiple gears are provided at the driving end, if the diameter of the counting piece 613 is too large, it will be detrimental to the layout of other gears and cause the miniaturization of the developing box 1 to fail; on the contrary, if the diameter of the counting piece 613 is too small, the rotation speed of the counting piece 613 will be accelerated, thereby causing increased wear between the various components of the driving force transmission assembly 4, and even causing the detection device 6 to fail in detection.

[0089] When the driving force receiving member 41 and the driving member 612 are both configured as gears, the gear ratio between the two is in the range of 0.7-1.3, preferably 0.8-1.1. In the scheme where the transmission member 62 adopts translation, this gear ratio is conducive to the miniaturization of the powder box end and improves the transmission accuracy.

[0090] [Structure of counting pieces]

[0091] like Figure 5 As shown, the multiple protrusions include a positioning protrusion 613d, a first toggle protrusion 613e and a second toggle protrusion 613f spaced apart along the circumferential direction of the chassis 613a, and a flat portion 613g is provided between two adjacent protrusions, wherein the first flat portion 613g1 is provided between the positioning protrusion 613d and the first toggle protrusion 613e, and the second flat portion 613g2 is provided between the first toggle protrusion 613e and the second toggle protrusion 613f. The number of the toggle protrusions can also be increased or decreased according to the detection requirements of the detection device.

[0092] [Structure and installation of transmission parts]

[0093] The transmission member 62 includes a forced pushing portion 621 (forced pushing portion 620) located at the driving end, a transmission portion 623 located at the detection end, and a moving portion 622 located between the forced pushing portion 621 and the transmission portion 623, wherein the forced pushing portion 621 is used to receive the driving force from the driving force receiving member 41 and is combined with the counting member 613, and the moving portion 622 is used to transmit the driving force to the transmission portion 623, and the transmission portion 623 is used to transmit the driving force to the acting component 63; further, the transmission member 62 also includes a reset member 67, when the transmission member 62 is pushed to the right / detection end, the reset member 67 accumulates the reset force, and when the transmission member 62 is no longer pushed, the reset force forces the transmission member 62 to move / reset to the left / driving end; in some embodiments, the reset member 67 may not be a separate component. At this time, the reset of the transmission member 62 drives the acting component 63 through the reset of the detected member 9, and then the acting component 63 forces the transmission member 62 to reset.

[0094] like Figure 3 As shown, along the third direction, the housing 2 includes an upper housing 2a located above and a lower housing 2b located below, the developer chamber 10 is located between the upper housing 2a and the lower housing 2b, and at least one of the developing member 31, the powder feeding member 32 and the stirring member 33 is rotatably arranged in the lower housing 2b, as shown in FIG. Figure 2 As shown, the guide groove 25 is arranged above the upper shell 2a, and the guide groove 25 is exposed upward, and the transmission member 62 is movably installed in the guide groove 25. In this way, the transmission member 62 will not interact with the developer during movement, and leakage of the developer is also avoided.

[0095] In some embodiments, the developing member 31 and the guide groove 25 may also be both provided on the upper housing 2 a.

[0096] The developer cartridge 1 further includes a cover 24 that prevents the transmission member 62 from falling out. The cover 24 covers the guide slot 25 from above. This prevents the transmission member 62 from falling out of the guide slot 25, protecting it from external contact. Furthermore, it enhances the aesthetics of the developer cartridge. The cover 24 can be coupled to the housing 2 by snapping, welding, bonding, magnetic attraction, or other methods.

[0097] In some embodiments, the cover 24 is further provided with an abutment protrusion for preventing the counting member 613 from reversing, so that the initial position of the counting member 613 starting detection can be determined.

[0098] In some embodiments, the cover 242 is further provided with a reset hole for allowing the counting member 613 to be reset. When viewed along the third direction, a portion of the counting member 613 is exposed through the reset hole, through which the user can reset the counting member 613 using a finger or a special tool.

[0099] In some embodiments, the acting component 63 has a surface for moving the second rod 92 , and when viewed along the first direction, the surface is located within the projection range of the counting member 613 , which is beneficial for reducing the size of the developing cartridge in the second direction.

[0100] like Figure 3A As shown, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 are arranged on the upper shell 2a. Along the first direction, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 are arranged at intervals. Along the second direction, the first forced pushing portion 2b1 and the second forced pushing portion 2b2 are both protruded downward from the rear of the upper shell 2a. This design can simplify the structure of the lower shell 2b which is provided with more parts.

[0101] like Figure 3D As shown, the first forced pushing portion 2b1 can also be provided on the left end cover 27 , and the second forced pushing portion 2b2 can also be provided on the right end cover 28 . This design is conducive to simplifying the structure of the housing 2 .

[0102] The driving force receiving member 41 includes at least one driving force receiving portion 41a spaced apart along its rotation direction, and the driving force receiving portion 41a is used to be combined with the driving force output member in the imaging device to receive the driving force from the driving force output member. Figure 3D As shown, along the radial direction of the driving force receiving member 41, the driving force receiving portion 41a is not blocked, and the interference to the driving force receiving member 41 can be reduced during the process of the driving force receiving member 41 and the driving force output member being combined with each other.

[0103] like Figure 3BAs shown, in some embodiments, the driving force receiving member 41 is further provided with an outer ring 41b. Along the radial direction of the driving force receiving member 41, the outer ring 41b is located radially outside the driving force receiving portion 41a. At this time, the driving force receiving portion 41a will be blocked.

[0104] When the upper shell 2a and the lower shell 2b are combined by welding, the welding surface 2g formed by the welding of the upper shell 2a and the lower shell 2b is located on at least one side wall of the lower shell 2b. When viewed along the first direction, the welding surface 2g does not coincide with the driving force receiving part 41. Along the third direction, the welding surface 2g is located above the rotation axis L1 of the driving force receiving part 41.

[0105] like Figure 3B As shown, in another housing 2, the upper housing 2a and the lower housing 2b can also be combined with each other in the second direction, and the guide groove 25 is provided on the upper housing 2a. When viewed along the first direction, the welding surface 2g does not coincide with the driving force receiving member 41, or the welding surface 2g is located outside the projection range of the driving force receiving member 41. Along the third direction, a portion of the welding surface 2g is located below the driving force receiving member 41 (as shown in FIG. Figure 3C in some embodiments, along the third direction, another portion of the welding surface 2g is located above the rotation axis L1 of the driving force receiving member 41.

[0106] Specifically, along the second direction, the welding surface 2g is located behind the driving force receiving member 41. In this way, not only can the impact of the vibration generated when the driving force receiving member 41 rotates on the welding surface 2g be reduced, but it can also ensure that there is enough space in the lower shell 2b. At the same time, the volume of the developer chamber 10 can be maximized.

[0107] like Figure 3C As shown, the welding surface 2g can also be tilted relative to the second direction / third direction. Figure 3C The dotted line in the figure shows the welding surface 2g tilted from the upper front to the lower rear. It can be understood that the welding surface 2g can also be tilted from the upper rear to the lower front.

[0108] During the working / developing process of the developing box 1, the developing member 31 needs to be in contact with the photosensitive drum 40 outside the developing box. However, when the developing box 1 is not working / developing, the developing member 31 and the photosensitive drum 40 should not continue to maintain contact. For this reason, a force-applying member is provided in the imaging device, and at the same time, a force receiving member is provided in the developing box 1. When the developing box 1 is not working / developing, the force-applying member applies and maintains a separation force to the force receiving member by abutting against the force receiving member, thereby forcing the developing member 31 and the photosensitive drum 40 to separate from each other. When the developing box 1 needs to work / develop again, the force-applying member no longer applies a separation force to the force receiving member, and the developing member 31 and the photosensitive drum 40 are in contact with each other again.

[0109] Alternatively, when the developing box 1 is not working / not developing, the force-applying member abuts against the force-receiving member so that the developing member 31 and the photosensitive drum 40 are separated from each other, and then the force-applying member and the force-receiving member are disengaged from the abutment. Through the retaining member provided in the developing box, the developing member 31 and the photosensitive drum 40 are maintained in a state of being separated from each other. When the developing box 1 needs to work / develop again, the force-applying member applies a restoring force to the force-receiving member, thereby forcing the developing member 31 and the photosensitive drum 40 to contact each other again.

[0110] Regardless of which method is used to achieve the contact and separation between the developing member 31 and the photosensitive drum 40, it is sufficient as long as at least a portion of the developing member 31 does not contact the photosensitive drum 40 when the developing cartridge 1 is not working / not developing. Figure 3E As shown, when the developing box 1 is working / developing, the developing member 31 is in contact with the photosensitive drum 40, and the rotation axis L1 of the developing member 31 and the rotation axis L4 of the photosensitive drum 40 are parallel to each other; when the developing box 1 is not working / developing, the rotation axis L1 of the developing member 31 intersects with the rotation axis L4 of the photosensitive drum 40.

[0111] For example, a force receiving member is provided in the developing cartridge 1. The force receiving member is located at the driving end or the detecting end along the first direction. When the force receiving member receives the separation force, the developing member 31 and the photosensitive drum 40 are separated from each other at the end where the force receiving member is provided. At the end where the force receiving member is not provided, the developing member 31 and the photosensitive drum 40 may still be in contact with each other or may be separated from each other, but the distance between the rotation axis L1 of the developing member 31 and the rotation axis L4 of the photosensitive drum 40 will change along the first direction. Figure 3F An example is shown in which a force receiving member is provided at the driving end. In this example, after the force receiving member receives the separation force, the developing member 31 rotates in the direction shown by r in the figure. At the driving end, the developing member 31 and the photosensitive drum 40 are separated from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along the first direction. Specifically, along the first direction, in the direction from the driving end to the detection end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases; on the contrary, when the force receiving member is provided at the detection end, after the force receiving member receives the separation force, at the detection end, the developing member 31 and the photosensitive drum 40 are separated from each other, and the distance between the rotation axis L1 and the rotation axis L4 gradually changes along the first direction. Specifically, along the first direction, in the direction from the detection end to the driving end, the distance between the rotation axis L1 and the rotation axis L4 gradually decreases.

[0112] In some embodiments, the force receiving member is a protrusion provided on the left end cover 27 .

[0113] In some embodiments, the force receiving member can also be at least a part of the outer ring 41b, so that the force member directly applies a separation force or a restoring force to the outer ring 41b, and then the outer ring 41b drives the housing 2 to move relative to the photosensitive drum 40, thereby realizing the mutual separation and mutual contact of the developing member 31 and the photosensitive drum 40; in this deformation mode, preferably, along the first direction, the outer ring 41b passes through the left end cover 27, and along the radial direction of the driving force receiving member 41, the outer ring 41b is not blocked by the left end cover 27, so that the force member can apply a separation force or a restoring force to the outer ring 41b.

[0114] [Structure of the active component]

[0115] like Figures 6A to 8F As shown, the action component 63 is configured to rotate around the axis L5. During the rotation, the action component 63 interacts with the detected part 9. The axis of rotation of the action component 63 can be parallel to any one of the first direction, the second direction and the third direction. In the following, the axis L5 perpendicular to the first direction is taken as an example.

[0116] The action assembly 63 includes a rotating portion 631 and an action protrusion 632 and a passive portion 633 extending from the rotating portion 631. The action protrusion 632 is arranged in a non-linear extension manner along a direction perpendicular to the rotation axis L5. It can extend directly from the rotating portion 631 or from a connecting portion 636 connected to the rotating portion 631. Figure 6C As shown, the action protrusion 632 is claw-shaped as a whole, and the groove / avoidance portion 6323 is provided in the action protrusion 632 and is recessed in the direction opposite to the rotation direction r3 of the action component 63. Figure 6A As shown, when the action protrusion 632 rotates with the rotating portion 631, the action portion 6324 of the action protrusion 632 will directly contact the surface 921 of the second rod 92 facing the action protrusion 632 (as shown in FIG.

[0117] Figure 8B As shown), the active protrusion 62 will not contact the edge 922 first and then contact the surface 921, and the edge 922 is the boundary line of the surface 921 close to the housing 2 / transmission member 62 / active component 63 side.

[0118] Continue as Figure 6A and Figure 6B As shown, two surfaces 6321 / 6322 of different heights are formed above the action protrusion 632, with a height difference between the two surfaces. In this way, the position where the action protrusion 632 contacts the second rod 92 can be moved downward. In this way, when the action protrusion 632 is configured to contact different positions of the detected member 9, the rotation speed of the detected member 9 can be made different, and the detection function can also be achieved.

[0119] Figure 7A and Figure 7B Another structure of the action protrusion 632 is shown. Different from the above embodiment, the action protrusion 632 in this embodiment is provided with an inclined surface 6325 and a plane 6326 on the side facing the second rod 92, and the groove / avoidance portion 6323 extends within the plane 6326 and the inclined surface 6325 along the third direction. When the action protrusion 632 contacts the second rod 92, the edge 922 will not contact the action protrusion 632, and the action portion 6324 directly contacts the surface 921.

[0120] The following combination Figure 9 、 Figure 10A and Figure 10B 、 Figure 11A and 11B 、 Figure 12A and Figure 12B A modified embodiment of the action assembly 63 will be described.

[0121] Transformation 1

[0122] like Figure 9 As shown, the action assembly 63 includes a toggle member 634 that can rotate around the rotation axis L5 and a movable member 64 for driving the toggle member 634. The movable member 64 includes a base 641 and a movable portion 642 that can move relative to the base 641. The movable member 642 is configured to rotate in only one direction. The toggle member 634 includes a central axis 6340 and a first toggle rod 6341, a second toggle rod 6342, and a ratchet 6343 combined with the central axis. The ratchet 6343 is configured to be pushed by the movable portion 642. Preferably, the ratchet 6343 is disposed in the center. At one end of the central shaft 6340, the first lever 6341 and the second lever 6342 extend radially outward from the surface of the central shaft 6340 respectively. Along the rotation axis L5, the first lever 6341 and the second lever 6342 are distributed at different axial positions, that is, the first lever 6341 and the second lever 6342 are at different distances from any end of the central shaft 6340, or in other words, the first lever 6341 and the second lever 6342 have a height difference, so that the positions of the detected part 9 moved by the first lever 6341 and the second lever 6342 are different.

[0123] During the detection process, the transmission part 623 moves to the right / detection end and pushes the movable member 64. Then, the movable part 642 pushes the ratchet 6343 to rotate, and the first lever 6341 or the second lever 6342 abuts against the second rod 92. When the transmission part 623 no longer pushes the movable member 64, the movable member 64 is pushed by a component such as an elastic member and resets. Figure 10A and Figure 10BAs shown, the first lever 6341 contacts the surface 921 of the second rod at point Q1. As the ratchet 6343 is turned, the detected member 9 is pushed to rotate around the rotating portion 93 in the direction shown by r until the first lever 6341 and the second rod are in contact.

[0124] 92 is disengaged, and as the ratchet 6343 continues to rotate, the second lever 6342 begins to contact the second rod 92 at point Q2. Compared with point Q1, point Q2 is farther away from the free end 923 of the second rod 92, that is, point Q2 is closer to the rotating portion 93 than point Q1. When the rotation speed of the ratchet 6343 remains unchanged, the detected part 9 will rotate faster under the push of the second lever 9342, thereby causing the detected part 9 to be accelerated.

[0125] Regarding the movable member 64, after the movable portion 642 pushes the ratchet 6343, while the elastic member forces the movable member 64 to return to its original position, the movable portion 642 is supported by the ratchet 6343 and rotates, so that the movable portion 643 can enter a position for the next push of the ratchet 6343. In some embodiments, the movable member 64 is connected to the transmission portion 623 and can move as the transmission portion 623 moves.

[0126] Transformation 2

[0127] In this modified embodiment, the action component 63 and the transmission member 62 are connected in a gear and rack manner, such as Figure 11A and 11B 、 Figure 12A and Figure 12B As shown, the transmission part 623 is configured as a rack, and the action assembly 63 includes a rotating part 631, an action protrusion 632 connected to the rotating part 631, and a passive part 633. The passive part 633 is configured as a gear. Preferably, the rotating part 631 and the gear 633 are coaxially arranged. When the transmission member 62 is pushed to the right / detection end, the rack drives the gear to rotate, which in turn causes the rotating part 631 to drive the action protrusion 632 to swing. During the swinging process of the action protrusion 632, the second rod 92 is toggled.

[0128] [Delayed movement of counting piece]

[0129] In some embodiments, the detected member 9 is configured to require the driving force receiving member 41 to be driven for a period of time before it begins to be moved. At this time, the rotational movement of the counting member 613 needs to be delayed, that is, the driving force received by the driving force receiving member 41 is not immediately transmitted to the counting member 613.

[0130] It is achievable that, along the rotation direction of the counting member 613, there is a predetermined distance between the driving force output portion 6122 of the driving member 612 and the driving force receiving portion 613c provided on the counting member 613. In this way, when the driving member 612 starts to rotate, the driving force will not be immediately transmitted to the counting member 613, and the counting member 613 remains stationary. When the driving force output portion 6122 contacts the driving force receiving portion 613c, the counting member 613 starts to rotate, and the delay requirement of the counting member 613 is realized.

[0131] like Figure 13 and Figure 14 As shown, the driving member 612 is driven by the stirring member gear 44, and the counting member 613 and the driving member 612 are integrally formed as an example. The stirring member gear 44 is configured as a double gear. Along the first direction, the stirring member gear 44 includes a first gear 441 located on the left and a second gear 442 located on the right. The first gear 441 is a full-tooth gear for receiving the driving force from the driving force receiving member 41. The second gear 442 is also a full-tooth gear for facing the driving member 612 and transmitting the driving force to the driving member 612.

[0132] The driving member 612 is a toothless gear, that is, on the same circumferential surface of the driving member 612, a part of the circumferential surface of the driving member 612 is provided with teeth to form a toothed portion 612a, and the other part has no teeth to form a toothless portion 612b; along the first direction, an intermediate portion 443 is formed between the first gear 441 and the second gear 442, and the toggle portion 4411 is provided in the intermediate portion 443. Corresponding to the toggle portion 4411, a toggle portion 612c is provided on the driving member 612. When the developing box is assembled, along the first direction, the toggle portion 4411 and the toggle portion 612c are both located between the first gear 441 and the second gear 442, the toggle portion 612c is located on the rotation path of the toggle portion 4411, and the toothless portion 612b is opposite to the second gear 442. That is to say, even if the agitator gear 44 starts to rotate around the rotation axis L7 along the rotation direction r2, the driving member 612 will not be driven.

[0133] As the stirring member gear 44 continues to rotate, the toggle portion 4411 begins to toggle the toggle portion 612c. At this time, the driving member 612 begins to rotate. When the toggle portion 4411 disengages from the toggle portion 612c, the toothed portion 612a begins to mesh with the second gear 442. In this way, the driving member 612 / counting member 613 is driven by the stirring member gear 44. Subsequently, the detected member 9 begins to be detected. The delay duration of the driving member 612 / counting member 613 is the time required for the toggle portion 4411 to start contacting the toggle portion 612c as the stirring member gear 44 starts to rotate. It is understandable that the designer can also adjust the position of the toggle portion 4411 according to the device's delay requirements for the detected member 9, so that the moment when the toggle portion 4411 starts contacting the toggle portion 612c changes.

[0134] Preferably, the toggle portion 4411 is integrally formed with one of the teeth of the first gear 441 , so that the strength of the toggle portion 4411 can be enhanced. Along the first direction, the toggle portion 4411 is closer to the second gear 442 than the teeth of the first gear 441 .

[0135] [Acceleration of the test piece]

[0136] As described above, in some embodiments, when the detection period of the detection device 6 is about to end (the end of the detection period), the detected member 9 needs to be accelerated, otherwise the developer cartridge will not be recognized by the device. To achieve the acceleration of the detected member 9, it can be achieved by accelerating the counting member 613, accelerating the transmission member 62, and moving the second rod 92 to different positions. Other implementation methods are described below.

[0137] Method 1

[0138] The following combination Figure 14 、 Figure 15A and Figure 15B Another method of accelerating the counter 613 will be described.

[0139] In this embodiment, the counting member 613 and the driving member 612 are still formed as one piece (eg Figure 14 As shown), the separation mechanism includes an elastic forced pushing member 611, and the driving member 612 is set as a toothless gear. Further, the driving member 612 also includes an arc surface 6124 coaxially arranged with the toothless gear and a straight surface 6125 adjacent to the arc surface. The elastic forced pushing member 611 is set as a torsion spring, one end of the torsion spring is in contact with the driving member 612, and the other end is in contact with the driving member 612.

[0140] External parts abut.

[0141] like Figure 15A and 15BAs shown, before the detection device 6 reaches the final detection stage, the torsion spring 611 contacts the arcuate surface 6124 and does not hinder the rotation of the driving member 612. When the detection device 6 reaches the final detection stage, the torsion spring 611 disengages from the arcuate surface 6124 and begins to contact the straight surface 6125. During the process of the torsion spring 611 switching the contact surface, the torsion spring 611 releases the torque, thereby forcing the driving member 612 to rotate faster. Furthermore, the driving member 612 is provided with an opening 6123 to facilitate the user to reset the torsion spring 611 from the outside.

[0142] Method 2

[0143] The acceleration of the driving member 612 can also be achieved by setting the second gear 442 of the stirring member gear 44 as a toothless gear, the diameter of the second gear 442 being smaller than the diameter of the first gear 441. At the same time, the driving member 612 is also set as a double gear. Along the first direction, the driving member 612 has a main gear meshing with the first gear 441 and a sub-gear opposite to the second gear 442. During the detection process, the first gear 441 drives the main gear to rotate. When reaching the detection end of the detection device 6, the first gear 441 disengages from the driving gear, and the second gear 442 begins to mesh with the sub-gear. Since the diameter of the second gear 442 is smaller than the diameter of the first gear 441, when the second gear 442 drives the sub-gear, the driving member 612 will be accelerated.

[0144] Example 2

[0145] On the basis of the above embodiment, this embodiment modifies part of the structure of the transmission member 62 , and the same components as those in the above embodiment are numbered the same.

[0146] like Figure 16A and Figure 16B As shown, the transmission member 62 includes a forced pushing member 620 located at the driving end, a transmission part 623 located at the detection end, and a moving part 622 located between the forced pushing member 620 and the transmission part 623; the action protrusion 632 is arranged on the side of the transmission part 623 close to the second rod 92, and the action protrusion 632 can be an additional component or the end of the transmission part 623 close to the second rod 92.

[0147] Furthermore, the forced push member 620, the moving part 622 and the transmission part 623 are formed in pairs. In this embodiment, the transmission member 62 also includes a guide groove 25 provided on the shell 2, and the guide groove 25 is located between a pair of guide plates 252. The pair of guide plates 252 protrude upward from the shell 2. In the second direction, the pair of guide plates 252 can be directly opposite to each other or staggered.

[0148] Furthermore, the forced pusher 620 is configured to rotate about a rotation axis L11. Preferably, the rotation axis L11 is not perpendicular to the third direction, and more preferably, the rotation axis L11 is parallel to the third direction. When the driving member 612 begins to rotate, the forced pusher 620 is configured to rotate in the direction indicated by r8. The moving portion 622 is configured to move in the first direction, and the transmission portion 623 is configured to move in the first direction along the guide groove 25. Furthermore, the forced push member 620 is provided with an intermediate column 6201 and a main body 6202 arranged circumferentially / radially along the intermediate column 6201. The forced push portion 621 protrudes radially from the intermediate column 6201 or protrudes axially from the main body 6202 for receiving the forced push force. At the same time, a plurality of protrusions 620b arranged adjacent to the forced push portion 621 can be used to receive a driving force to rotate the forced push member 620 around the rotation direction r8, thereby driving the moving portion 622 and the transmission portion 623 to move in the first direction away from the detection end (one end 51 of the first direction), thereby preventing the action protrusion 632 from toggling the second rod 92, so that a delay effect can be achieved; as the forced push member 620 continues to rotate along the rotation direction r8 , when the multiple protrusions 620b no longer receive the driving force, the moving part 622 and the transmission part 623 are driven to move in the first direction toward the direction close to the detection end (the other end 52 of the first direction), and the action protrusion 632 toggles the second rod 92 and remains engaged with the second rod 92. Preferably, the forced pushing member 620 is configured as a toothed gear. In this way, the portion without the multiple protrusions 620b does not contact the driving member 612, so that the forced pushing member 620 no longer rotates in the direction indicated by r8. Subsequently, the reset member 64 pushes the transmission member 62 to reset, or as the second rod 92 resets, the second rod 92 in turn pushes the transmission member 62 to reset; as the driving member 612 continues to rotate, the toggle portion 4411 (such as Figure 13 As shown in the figure, the forced push part 621 is combined with the forced push part 621, so that the forced push part 620 rotates an angle, thereby driving the moving part 622 and the transmission part 623 to move in the first direction away from the detection end (one end 51 of the first direction), thereby causing the action protrusion 632 to leave the second rod 92, that is, the second rod 92 is pushed again.

[0149] Furthermore, a crank-connecting rod structure is formed between the forced pusher 620 and the moving portion 622 in this embodiment.

[0150] Example 3

[0151] On the basis of the above embodiment, this embodiment modifies part of the structure of the transmission member 62 , and the same components as those in the above embodiment are numbered the same.

[0152] like Figure 17A and Figure 17BAs shown, the transmission member 62 includes a forced push member 620 located at the driving end, a transmission part 623 located at the detection end, and a moving part 622 located between the forced push member 620 and the transmission part 623. The forced push member 620 is configured to rotate around the rotation axis L9, and the transmission part 623 is configured to rotate around the rotation axis L10. Preferably, the rotation axis L9 and the rotation axis L10 are not perpendicular to the third direction respectively. More preferably, the rotation axis L9 of the forced push member 620 and the rotation axis L10 of the transmission part 623 are parallel to the third direction respectively.

[0153] The forced push member 620 is used to combine with the counting member 613. Specifically, the forced push portion 621 is configured to protrude radially from the forced push member 620 to combine with the counting member 613 and receive the forced push force. That is, the forced push member 620 is driven by the counting member 613, or the driving force of the driving member 612 is transmitted to the forced push member 620 through the counting member 613. Therefore, the counting member 613 can also be called a transition member in the detection device 6, and the transition member 613 is configured to be a rotating body with partially missing teeth in its circumferential direction; the action protrusion 632 is formed integrally or separately with the transmission part 623. When the transmission part 623 rotates around the rotation axis L10, the action protrusion 632 moves with the transmission part 623, such as rotating or translating, to interact with the second rod 92.

[0154] Different from the above embodiment, in this embodiment, the moving part 622 is set as a flexible member such as a flexible belt or a flexible rope, and the flexible member 622 can move back and forth in the first direction. Further, one end of the flexible member 622 is connected to the forced pushing member 620, and the other end is connected to the transmission part 623; preferably, the flexible member 622 does not need to be wound around the forced pushing member 620 or the transmission part 623; the reset member 67 is used to reset the action protrusion 632 for the next detection. Further, the transmission part 623 is provided with a shaft extending in the axial direction toward the housing 2. Body 623c, the shaft body 623c is used to combine with the shell 2 so that the transmission part 623 can be installed. The reset member 67 in this embodiment is configured to combine with the transmission part 623. Further, the reset member 67 is a torsion spring, which is sleeved on the shaft body 623c. The torsion spring 67 has a first end 67a and a second end 67b, wherein the first end 67a abuts against the slot 623d set in the transmission part 623, and the second end 67b abuts against the shell 2. Further, the slot 623d is formed by radially inward depression from the outer surface 623b of the transmission part 623.

[0155] The forced pushing portion 621 receives the forced pushing force, causing the forced pushing member 620 to rotate in the direction indicated by r6, thereby driving the moving portion 622 to pull the transmission portion 623 in the first direction to rotate in the direction indicated by r7, and then causing the action protrusion 632 to move the second rod 92. At this time, the reset member 67 is squeezed and accumulates the reset force. When the forced pushing portion 621 no longer receives the forced pushing force, the reset force of the reset member 67 causes the transmission portion 623 to rotate in the direction opposite to the direction indicated by r7, thereby driving the moving portion 622 in the first direction to pull the forced pushing member 620 to rotate in the direction opposite to the direction indicated by r6, and at the same time, the action protrusion 632 no longer moves the second rod 92, and the action protrusion 632 is reset.

[0156] In this embodiment, the flexible member is used as the moving portion 622, which can solve the technical problem of excessive load on the stirring rod in the background art. It can also make the position of the transmission portion 623 and the actuating protrusion 632 more flexible, which is conducive to improving the design freedom of the developer cartridge 1. In addition, the flexible member is not easy to break and has better stability.

[0157] In other embodiments, the moving portion / flexible member 622 may be directly connected to the counting member 613 , which may simplify the structure of the transmission member 62 .

[0158] Example 4

[0159] The same components in this embodiment as those in the above embodiments are numbered the same.

[0160] like Figure 18 As shown, the transmission member 62 includes a transmission portion 623 located at the detection end and a moving portion 622 connected to the transmission portion 623. The transmission portion 623 is configured to rotate about a rotation axis L10. Preferably, the rotation axis L10 is not perpendicular to the third direction. More preferably, the rotation axis L10 of the transmission portion 623 is parallel to the third direction. Similar to the third embodiment, the moving portion 622 in this embodiment is also configured as a flexible member such as a flexible belt or flexible rope. One end of the flexible member 622 in this embodiment is directly connected to the counter member 613, and the other end is connected to the transmission portion 623. Moreover, during detection, the flexible member 622 is wrapped around the counter member 613 and released by the transmission portion 623. In addition, one or more active protrusions 632 can be provided according to detection needs. In this embodiment, three active protrusions 632 are provided, including a first active protrusion 632a, a second active protrusion 632b, and a third active protrusion 632c. Furthermore, the active protrusion 632 can be formed integrally with or separately from the transmission portion 623.

[0161] During detection, the driving member 612 drives the counting member 613 to rotate in the direction indicated by r5, and the flexible member 622 is pulled and wrapped around the counting member 613, thereby driving the transmission part 623 to rotate in the direction indicated by r7, so that the three action protrusions 632 touch the second rod 92 in turn. At the same time, the flexible member 622 wrapped around the transmission part 623 is released.

[0162] It is practicable that the counting member 613 in this embodiment is also configured as a rotating body having partially missing teeth in its circumferential direction.

[0163] This embodiment can achieve the same technical effects as the third embodiment, so it will not be described in detail.

[0164] Example 5

[0165] The above embodiment introduces that the second forced pushing portion 2b2 is set on the shell 2 or the right end cover 28. In some embodiments, the second forced pushing portion 2b2 can also be set at other positions. For example, the second forced pushing portion 2b2 is set on the sealing cover 2a4. This design is conducive to simplifying the structure of the shell 2, and the second forced pushing portion 2b2 can also serve as an operating portion for the user to operate the sealing cover 2a4.

[0166] In some embodiments, the second forced pushing portion 2b2 can also be provided in an independent component 2i (eg Figure 19 As shown in FIG, the function of the independent component 2i can be designed according to the design requirements of the developing cartridge 1. For example, a portion of the detecting device 6 is supported by the independent component 2i. In this embodiment, the right end cover 28 can be regarded as an independent component 2i.

[0167] like Figure 19 As shown, along the first direction, the powder filling port 2a3 is arranged on the same side as the action component 63, along the third direction, the powder filling port 2a3 does not overlap with the action component 63, and along the second direction, the powder filling port 2a3 is located in front of the independent component 2i. This design can ensure that the powder filling port 2a3 is directly exposed, so that the user can replenish the developer into the developer chamber 10 without having to disassemble the parts of the developer box, and can also reduce the size of the independent component 2i in the front-to-back direction, thereby reducing the cost of the independent component 2i and improving the strength of the independent component 2i. Preferably, along the third direction, a portion of the independent component 2i overlaps with the action component 63. Figure 19 As shown, when viewed along the first direction, the rotation axis L2 of the driving force receiving member 41 / intermediate gear 46 does not pass through the conductive member 26. In this way, the electrical contact between the conductive member 26 and the power output member in the imaging device is less affected by the vibration generated when the driving force receiving member 41 rotates, and the stability of the electrical contact can be improved.

[0168] Furthermore, when observed along the first direction, the power input portion 26b of the conductive member 26 is located outside the projection range of the driving force receiving member 41. This design can improve the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device; further, the power input portion 26b is also located outside the projection range of the intermediate gear 46, thereby further improving the stability of the electrical contact between the power input portion 26b and the power output member in the imaging device.

[0169] The above-mentioned embodiments 2 to 5 no longer transmit the driving force through the stirring member 33, which can reduce the load of the stirring member 33, thereby preventing the stirring member 33 from being broken, and the forced pusher and the moving part are formed separately. In this way, the strength of each component can also be increased, thereby avoiding deformation or transmission lag caused by insufficient strength due to the length of a component in the first direction being too long. In addition, a flexible member with better stability is used as the moving part, thereby improving the durability and detection accuracy of the detection device.

[0170] Example 6

[0171] Based on the above embodiment, the present invention also provides a developing box without a stirring frame 33 to simplify the structure of the developing box and save costs. Figure 20 As shown, the stirring rack 23 is no longer provided in the developer chamber 10. To ensure that the developer reaches the developing part 31 and the powder feeding part 32 smoothly, the lower side plate 2b3 of the lower shell 2b is arranged to be inclined relative to the second direction. Specifically, the inner surface 2b4 of the lower side plate 2b3 facing the developer chamber 10 is inclined relative to the second direction. Thus, the structure of the developer box 1 can be simplified, and the user can also directly contact the lower side plate 2b3 with his hands when installing and disassembling the developer box 1. Compared with the handle 23, the lower side plate 2b3 has a larger area for the user to grasp.

[0172] exist Figure 20 In the angle shown, the first straight line P1 passes through the rotation axis L1 of the developing member 31 and the rotation axis L2 of the driving force receiving member 41 at the same time, and the second straight line P2 is parallel to the inner surface 2b3. The first straight line P1 and the second straight line P2 intersect at point P0, and the angle γ formed therebetween satisfies: 0°<γ≤45°, preferably, 5°<γ≤20°.

[0173] Example 7

[0174] Based on the above embodiment, this embodiment continues to introduce the limiting structure in the detection device.

[0175]

Limiting structure

[0176] In order to prevent the transmission part 623 / the action protrusion 632 from rotating in the direction indicated by r7 during transportation or due to user's misoperation, thereby affecting the detection result of the detection device, the developing box 1 is further provided with a limiting structure.

[0177] Method 1

[0178] like Figure 21A As shown, in this embodiment, the limiting structure is provided as a limiting member 30. Preferably, the limiting member 30 is mounted on the cover 24 or the housing 2. When the developer cartridge 1 needs to be operated, the limiting member 30 can be directly removed from the cover 24 or the housing 2. Specifically, the limiting member 30 is provided with a limiting portion / limiting plate 301 extending in the third direction. The limiting portion / limiting plate 301 is used to abut against the active protrusion 632 to at least prevent the active protrusion 632 from rotating in the direction indicated by r7, thereby avoiding a reduction in detection accuracy. In other embodiments, the limiting portion / limiting plate 301 can be provided with a notch or protrusion as needed.

[0179] Method 2

[0180] like Figure 21B and Figure 21C As shown, this embodiment provides another limiting structure. Specifically, the limiting structure is provided as an elastic member 68. Preferably, the elastic member 68 is a torsion spring. The first end 68a of the elastic member 68 is used to abut against the protrusion 623f of the transmission portion 623 in the radial direction, and the second end 68b of the elastic member 68 is used to abut against the housing 2. Furthermore, the protrusion 623f has a first end 623f1 and a second end 623f2. Along the direction indicated by r7, the first end 623f1 is located downstream of the second end 623f2. Furthermore, the first end 68a of the elastic member 68 is used to abut against the second end 623f2 of the protrusion 623f to at least prevent the active protrusion 632 from rotating in the direction opposite to the direction indicated by r7, thereby avoiding a reduction in detection accuracy.

[0181] In other methods, method 1 and method 2 can also be combined.

[0182] Example 8

[0183] Based on the seventh embodiment, this embodiment continues to introduce the acceleration structure in the detection device.

[0184]

Acceleration Structure

[0185] Method 1

[0186] like Figures 22A-22DAs shown, in this embodiment, the acceleration structure is provided as an elastic member 68. Preferably, the elastic member 68 is a torsion spring. The first end 68a of the elastic member 68 is used to abut against the protrusion 623f of the transmission part 623 in the radial direction. A step is formed between the protrusion 623f and the circumferential surface 623g of the transmission part 623. There is a height difference between the protrusion 623f and the circumferential surface 623g. The two can be connected in a plane or in a curved surface. The second end 68b of the elastic member 68 is used to abut against the shell 2. Furthermore, the protrusion 623f has a first end 623f1 and a second end 623f2. Along the direction shown by r7, the first end 623f1 is located downstream of the second end 623f2. Furthermore, when the transmission part 623 rotates and counts in the direction indicated by r7, the first end 68a of the elastic member 68 passes over the first end 623f1 of the protrusion 623f and abuts against the protrusion 623f. As the transmission part 623 continues to rotate in the direction indicated by r7, the first end 68a passes over the second end 623f2 and falls from the protrusion 623f, forcing the transmission part 623 to rotate faster.

[0187] Method 2

[0188] like Figures 23A-23D As shown, the acceleration structure is provided as an elastic member 68. Unlike the first embodiment, in this embodiment, the elastic member 68 is preferably a compression spring. The first end 68a of the elastic member 68 is used to abut against the transmission portion 623 / the actuating protrusion 632, and the second end 68b of the elastic member 68 is used to abut against the housing 2. Furthermore, the first end 68a of the elastic member 68 forms a triangle. Specifically, the first end 68a has a first contact portion 68a1, a second contact portion 68a2, and a third contact portion 68a3. The first contact portion 68a1 faces one end 55 in the third direction, and the second contact portion 68a2 and the third contact portion 68a3 are two sides of the triangle. Furthermore, the protrusion 623f of the transmission portion 623 in the radial direction has a first end 623f1 and a second end 623f2. Furthermore, the protrusion 623f is also provided with a guide portion 623f3 arranged adjacent to the first end 623f1. Along the direction indicated by r7, the guide portion 623f3 is located downstream of the second end 623f2, and the first end 623f1 is located downstream of the guide portion 623f3.

[0189] The transmission part 623 moves in the direction indicated by r7 (as shown in FIG. Figure 21BAs shown in the figure, when the rotation count is performed, the action protrusion 632 first abuts against the first end 68a of the elastic member 68, so that the elastic member 68 can be more stable. Specifically, the action protrusion 632 abuts against the first contact portion 68a1 of the first end 68a in the third direction. Then, the first end portion 623f1 of the protrusion 623f moves along the second contact portion 68a2 of the first end 68a and passes over the first contact portion 68a2. At the same time, the first end 68a is squeezed to move toward the other end 56 in the third direction. The elastic member 68 The guide portion 623f of the projection 623f abuts against the first end 68a, causing the first end 68a to move further toward the other end 56 in the third direction, until the side of the action projection 632 toward the other end 56 in the third direction abuts against the first end 68a. The elastic member 68 is further compressed, and the transmission portion 623 continues to rotate in the direction indicated by r7. The third contact portion 68a3 of the first end 68a pushes the second end 623f2 of the projection 623f, thereby accelerating the rotation of the transmission portion 623. In other embodiments, the transmission portion 623 moves in the direction indicated by r7 (e.g., Figure 21B When the rotation count is started (as shown), the first end 68a of the elastic member 68 may not abut against the action protrusion 632.

[0190] Method 3

[0191] like Figures 24A-24C As shown, unlike the first and second methods, in this method, the acceleration structure is provided on the counting piece 613. Furthermore, the counting piece 613 is provided with an acceleration member 613r along the circumferential direction. The acceleration member 613r is formed integrally with or separately from the counting piece 613. Furthermore, an extension portion 613p1 is provided on the circumferential outer side of the positioning column 613p of the counting piece 613. Specifically, when the acceleration member 613r is formed integrally with the counting piece 613, the acceleration member 613r extends from the extension portion 613p1 of the positioning column 613p, or extends from the chassis 613a. When the counting member 613 rotates and counts in the direction opposite to the direction indicated by r5, the moving portion 622 made of a flexible member is wrapped around the extension portion 613p1. When the counting member 613 continues to rotate, the moving portion 622 is wrapped around the accelerating member 613 and is pushed out by the accelerating member 613 in the radial direction away from the extension portion 613p1. The moving portion 622 is pulled and accelerated, thereby causing the action protrusion 632 to rotate faster.

[0192] One or more of the implementation methods involved in this embodiment can be combined with one or more of the above-mentioned embodiments 1 to 7 for application.

[0193] Embodiment 9

[0194] Based on the twentieth embodiment, this embodiment continues to introduce the reset structure in the detection device.

[0195]

Reset structure

[0196] Method 1

[0197] like Figure 25A As shown, in this embodiment, the reset can be performed by rotating the transmission part 623 / action protrusion 632. Specifically, the transmission part 623 is provided with a reset coupling part 6233 located at one end 55 in the third direction. Preferably, the reset coupling part 6233 is configured as a groove. After the detection device completes counting, when the detection device needs to be reset, the transmission part 623 / action protrusion 632 can be rotated by using a screwdriver in conjunction with the groove part 6233. Alternatively, the reset can be performed by directly manually rotating the action protrusion 632. In other embodiments, the reset coupling part 6233 can also be configured as a protrusion, so that it can be reset using a tool such as a wrench.

[0198] By rotating the transmission part 623 / the action protrusion 632, the moving part 622 is driven to rotate, and then the counting part 613 and the driving part 612 are driven to rotate until the second indicating part 6121 on the driving part 612 is aligned with the first indicating part 273 on the left end cover 27. In this way, it can be determined that the detection device is in the initial state and the next detection / counting can be carried out.

[0199] In addition, if Figure 25B As shown, in this embodiment, the driving force output portion 6122 of the driving member 612 includes a toothed portion 6122a and a toothless portion 6122b. Similarly, the driving force receiving portion 613c of the counting member 613 includes bevel teeth (toothed portion 612a) and a toothless portion 612b. The driving member 612 and the counting member 613 are provided with toothless portions at the same time. In this way, when the detection device is reset, the counting member 613 and the driving member 612 will not interfere with each other, which is more conducive to the reset of the detection device.

[0200] In addition, continue as Figure 25B As shown, this embodiment also provides a delay component for delaying the detection device before starting counting. The delay component includes a toggle portion 4411 arranged on the driving member 612 and a toggle portion (not shown) arranged on the counting member 613. When the driving member 612 just starts to rotate, the counting member 613 does not rotate. After the toggle portion 4411 rotates a predetermined angle along with the driving member 612, the toggle portion 4411 triggers the toggle portion, and the counting member 613 starts to rotate, thereby achieving the purpose of delaying counting of the detection device.

[0201] Method 2

[0202] like Figure 25CAs shown, in this embodiment, an elastic member 69 is provided at one end 51 in the first direction. Preferably, the elastic member 69 is a compression spring. One end of the elastic member 69 abuts against the driving member 612, and the other end abuts against the left end cover 27. The elastic member 69 can be extended and retracted in the first direction. Under the elastic force of the elastic member 69, the driving member 612 maintains abutment against the counting member 613. When the detection device needs to be reset after counting, the driving member 612 is first moved toward the one end 51 in the first direction so that the elastic member 69 is compressed. At the same time, the driving member 612 is rotated as shown in FIG. Figure 25A The transmission portion 623 / the action protrusion 632 shown is reset, and then the driving member 612 is released, and the driving member 612 is again kept in contact with the counting member 613 under the elastic force of the elastic component 69.

[0203] In this embodiment, the driving member 612 may be a full-tooth gear, that is, the driving force output portion 6122 of the driving member 612 does not need to be provided with a toothless portion.

[0204] like Figure 26 As shown, the moving part (flexible part) 622 is wrapped around the counting part 613 and the transmission part 623. When the counting part 613 and the transmission part 623 rotate in the same direction, the moving part 622 is wrapped around one of the counting part 613 and the transmission part 623, and is released from the other of the counting part 613 and the transmission part 623. Furthermore, a first plane 613p2 is provided on the extension part 613p1 of the counting part 613, and a second plane 623h is provided on the transmission part 623. The moving part 622 is aligned with the first plane 613p2 and the second plane 623h at both ends in the first direction. In this way, the accuracy of the detection device can be ensured to prevent the inaccurate position of the moving part 623 from causing the counting of the detection device to fail. Furthermore, this structure is suitable for a structure in which the moving part 622 is configured as a flexible part.

[0205] In addition, to prevent the moving portion 622 from being torn and separated from the first plane 613p2 / expansion portion 613p1 when the counting member 613 is reversed, the counting member 613 is provided with a blocking member 613s. Specifically, the blocking member 613s is provided radially outward of the expansion portion 613p1, and the moving portion 622 is clamped between the expansion portion 613p1 and the blocking member 613s. In a direction perpendicular to the first plane 613p2, the blocking member 613s can be farther from the rotation axis L8 than the first plane 613p2, or closer to the rotation axis L8 than the first plane 613p2. Preferably, in a direction perpendicular to the first plane 613p2, the blocking member 613s is closer to the rotation axis L8 than the first plane 613p2. In this way, the moving portion 622 can be better blocked by the blocking member 613s, thereby better protecting the moving portion 622 from being torn and separated from the first plane 613p2. Further, this structure is suitable for a structure in which the moving portion 622 is provided as a flexible member.

[0206] Example 10

[0207] like Figure 27A and Figure 27B As shown, this embodiment further provides a flexible member installation device 000 , which is used to install the moving part (flexible member) 622 onto the counting member 613 and the transmission part 623 .

[0208] Specifically, the flexible part installation device 000 includes a first installation portion 001 arranged at one end 51 in the first direction and a second installation portion 002 arranged at the other end 52 in the first direction. The first installation portion 001 and the second installation portion 002 only need to be connected by a connecting plate 003, and no other structure is required. This can save materials and reduce the weight of the flexible part installation device 000. In order to enhance the strength of the flexible part installation device 000, a first reinforcing plate 004 and a second reinforcing plate 005 are arranged between the first installation portion 001 and the second installation portion 002, wherein the first reinforcing plate 004 and the second reinforcing plate 005 are respectively perpendicular to the connecting plate 003, and the first reinforcing plate 004 is also perpendicular to the second reinforcing plate 004.

[0209] Furthermore, the first mounting portion 001 is used to fix the counting member 613, and the second mounting portion 002 is used to fix the transmission portion 623 / action protrusion 632. When the counting member 613 and the transmission portion 623 / action protrusion 632 are placed in place, that is, the first plane 613p2 of the counting member 613 and the second plane 623h of the transmission portion 623 are facing above the operator's line of sight, so that the installation of the moving portion 622 can continue.

[0210] Furthermore, the first mounting portion 001 is provided with a first mounting groove 0011 that cooperates with a portion of the counter 613. The first mounting groove 0011 has a structure for supporting the bevel gear (having a tooth portion 612a, such as Figure 25B ) can prevent the counting piece 613 from rotating, so that the counting piece 613 is fixed; the second mounting portion 002 is provided with a second mounting groove 0021 which cooperates with a part of the transmission portion 623 / action protrusion 632, and the second mounting groove 0021 has a second supporting surface 0022 for supporting the action protrusion 632, which can prevent the transmission portion 623 / action protrusion 632 from rotating, so that the transmission portion 623 / action protrusion 632 is fixed.

[0211] Furthermore, the first mounting portion 001 is further provided with a support block 006 for supporting the blocking member 613s, so as to facilitate the installation of the moving portion 622. Furthermore, the flexible member mounting device 000 is applicable to a structure in which the moving portion 622 is provided as a flexible member.

[0212] Furthermore, when installing the moving portion / flexible member 622, first align one end of the moving portion 622 with the end of the first plane 613p2 of the counter member 613 at one end 51 in the first direction, and align the moving portion 622 with the first plane 613p2. Then, straighten the moving portion 622 so that it aligns with the second plane 623h of the transmission member 623. Finally, separate the remaining flexible member from the installed flexible member at the end of the second plane 613h at the other end 52 in the first direction, which can be done by cutting or other separation methods. The bonding method can be gluing, welding, etc. Alternatively, the flexible member can be pre-cut to the desired length before installation.

[0213] Furthermore, when installing the moving portion / flexible member 622, the flexible member 622 can be first attached to the first plane 613p2 and the second plane 613h, and then the flexible member 622 can be cut along the end 51 of the first plane 613p2 in the first direction and along the end 52 of the second plane 613h in the first direction. The attachment method can be gluing, welding, etc.

[0214] It should be noted that the length of the installed moving part / flexible member 622 in the first direction can be determined according to the needs of the detection device. Therefore, for moving parts / flexible members 622 of different lengths, the size of the flexible member installation device 000 in the first direction is also different.

[0215] Furthermore, in response to requirements for moving parts / flexible members 622 of different lengths, the flexible member installation device 000 may be configured to have an adjustable distance in the first direction.

[0216] Example 11

[0217] This embodiment continues to improve the above embodiment. As mentioned above, the moving part 622 transmits the driving force of the driving force receiving part 41 to the action protrusion 632 through the transmission part 623 and the rotating part 631 in sequence. Finally, the action protrusion 632 interacts with the detected part 9, so that the developing box 1 completes the detection.

[0218] like Figure 28 、 Figure 29 and Figure 30 As shown, in this embodiment, the action protrusion 632 is configured to move along the Figure 29 The middle rotation direction r7 rotates around the rotation axis L10. When the moving part 622 is set as a flexible part extending along the first direction, generally, when the developer box 1 is assembled, the flexible part 622 is in a tensioned state. Therefore, before the developer box 10 is installed on the imaging device, once the components at the driving end shake or the user makes an erroneous operation, the action protrusion 632 may be driven to rotate along the rotation direction (detection direction) r7, thereby causing a detection error.

[0219] To this end, the developing box 1 involved in this embodiment is also provided with a limiting member 30, and the limiting member 30 is movable relative to the shell 2. Specifically, the limiting member 30 has a limiting position and a releasing position. In the limiting position, the rotation tendency of the action protrusion 632 / action component 63 along the direction shown by r7 in the figure can be suppressed by the limiting member 30. In the releasing position, the limiting member 30 no longer suppresses the rotation tendency of the action protrusion 632 / action component 63 along the direction shown by r7 in the figure; before the developing box 1 is installed to the imaging device, the limiting member 30 is located in the limiting position. As the developing box 1 is installed toward the imaging device, the limiting member 30 interacts with the releasing member provided in the developing box 1 or the imaging device and gradually moves from the limiting position to the releasing position.

[0220] In practice, the limit release member can be set in the developer box or can be a component in the imaging device. For example, the limit release member is the handle 23 of the developer box. When the user grasps the handle 23 to install the developer box, the force applied by the user to the handle 23 forces the limit member 30 to unlock. Alternatively, the limit release member is a side wall forming an installation entrance of the imaging device, and the side wall is specifically located on the right side of the installation entrance. The developer box is installed to the imaging device through the installation entrance. Alternatively, the limit release member is a protrusion in the imaging device, and the protrusion is located on the installation path of the developer box in the imaging device. As the developer box is installed, the protrusion abuts against the limit member 30 to unlock the limit member 30.

[0221] In some embodiments, at the limiting position, the action protrusion 632 and the limiting member 30 abut against each other, so that the initial position of the action protrusion 632 can be positioned more accurately.

[0222] In some embodiments, the limit member 30 is configured to move linearly along a predetermined trajectory, for example, the limit member 30 abuts against the release limit member, so that the limit member 30 moves toward the rear of the developing box, or the limit member 30 moves along a third direction, or the limit member 30 moves in a direction inclined relative to the second direction or the third direction, as long as the tendency of the action protrusion 632 to move in the direction shown by r7 in the figure is no longer suppressed by the limit member 30.

[0223] In some embodiments, the limiting member 30 is configured to move along a predetermined trajectory, for example, Figure 29 As shown, the limit member 30 is configured to rotate along r30 around the rotation axis L30. Similarly, the rotation direction r30 and the rotation direction r7 do not need to be limited, and the extension direction of the rotation axis L30 does not need to be limited. As long as the limit member 30 and the release limit member abut against each other, the tendency of the action protrusion 632 to move along the direction shown by r7 in the figure is no longer suppressed by the limit member 30.

[0224] Furthermore, the rotation direction r30 is opposite to the rotation direction r7, and the extension direction of the rotation axis L30 is parallel to the third direction.

[0225] The limiting member 30 includes a limiting body 302 and a limiting portion 302 and a movable guiding portion 303 arranged on the limiting body 302. The limiting portion 302 is used to suppress the movement of the action protrusion 632 along the direction shown by r7 in the figure. The releasing limiting member can interact with the limiting body 302, the limiting portion 302 and other components to make the limiting member 30 move from the limiting position to the releasing limit position; when the limiting member 30 is set to move along a straight line, the movable guiding portion 303 can be formed into a protrusion-shaped or groove-shaped guide track. When the limiting member 30 is set to move in a curve, the movable guiding portion 303 is combined with the shell 2 by matching the shaft hole.

[0226] In some embodiments, the limiting member 30 is configured to be able to reciprocate between the limiting position and the releasing position. At this time, the developing box 1 also includes a reset member for combining with the limiting member 30. For example, the reset member is configured to be a spring, torsion spring, sponge, rubber, etc. that abuts against the limiting member 30.

[0227] In some embodiments, when the moving part 622 is not configured as a flexible part, the technical solution of this embodiment is still applicable. For example, the moving part 622 is configured as a plurality of mutually meshing gears, or the moving part 622 is configured as a rod that reciprocates along a first direction, etc.; in addition to being able to interact with the detected part 9 by rotation, the action protrusion 632 / action component 63 can also interact with the detected part 9 by sliding / translation.

[0228] Continue as Figure 30 As shown, the second forced pushing portion 2b2 in this embodiment is still set as a part 282 of the right end cover 28 / independent component 2i, and the shell 2 also includes an extension portion 2b5 extending backward from the lower shell 2b. Unlike the above embodiment, the right end cover 28 in this embodiment is not only connected to the above-mentioned shell 2a or the lower shell 2b, but also connected to the extension portion 2b5, that is, the right end cover 28 is connected to the shell 2 and the extension portion 2b5 at the same time.

[0229] The right end cover 28 includes an end cover body 283 and a second forced push portion 2b2 connected to the end cover body 283. The end cover body 283 is connected to at least the upper shell 2a or the lower shell 2b. Furthermore, the right end cover 28 also includes a connecting body 284 connected to the end cover body 283. The right end cover 28 is detachably connected to the shell 2 through the connecting body 284.

[0230] In some embodiments, the number of connectors 284 is two, wherein one connector 284 is connected to the upper shell 2a or the lower shell 2b, and the other connector 284 is connected to the extension portion 2b5, so that the right end cover 28 can be installed more stably.

[0231] In some embodiments, at least one of the housing 2 and the extension portion 2b5 may be connected to the connector 284 in other ways, such as by screw fixation, welding, gluing, etc.

[0232] In some embodiments, when the right end cover 28 is connected to the shell 2, along the first direction, the end cover body 283 / the second forced pushing portion 2b2 and the extension portion 2b5 are spaced apart from each other, or in other words, along the second direction, when viewed from the rear to the front of the developing box, a gap is formed between the end cover body / the second forced pushing portion and the extension portion, so that the forced pushing force received by the second forced pushing portion 2b2 can be more effectively transmitted to the upper shell 2a or the lower shell 2b through the right end cover 28, and the risk of the extension portion 2b5 being broken can be reduced.
