Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic imaging equipment consumables, in particular to a toner cartridge and a working method of a detection wheel assembly thereof. BACKGROUND

[0002] The existing toner cartridge is provided with a detection wheel assembly to cooperate with a detection mechanism on the printer to detect the toner cartridge after the toner cartridge is installed on the printer, such as whether the toner cartridge is used for the first time, the type of the toner cartridge, the capacity of the toner cartridge, whether the toner cartridge is installed in place, etc. The toner cartridge mainly comprises a cartridge body, a stirring frame, a powder feeding roller, a developing roller and a power receiving head, and the detection wheel assembly mainly comprises a detection wheel.

[0003] When the toner cartridge is installed on the printer for the first time, the detection wheel assembly contacts the detection mechanism of the printer, then the driving head of the printer drives the power receiving head to rotate, so that the power receiving head drives the detection wheel to rotate through the transmission mechanism, when the detection wheel rotates by a preset angle, the detection mechanism performs detection on the detection wheel assembly to determine whether the toner cartridge is used for the first time, the type of the toner cartridge, the capacity of the toner cartridge, the number of printed paper sheets, etc. After the detection is completed, the detection wheel is no longer driven by the power receiving head and the transmission mechanism. Since the existing detection wheel only rotates once and then stops working, and the toner cartridge is identified by one-time irreversible instantaneous detection, when the toner cartridge is refilled and installed again, the printer cannot detect the toner cartridge due to the failure of the detection wheel to reset, so the toner cartridge cannot be used because it cannot be identified.

[0004] Another existing printer has a detection wheel that can automatically reset to enable the toner cartridge to be identified by the printer multiple times. However, if the printer malfunctions due to paper jamming or other reasons, and the user removes the toner cartridge and then installs it again in the printer, the detection wheel will automatically reset, the printer will identify the toner cartridge as a new toner cartridge, and the counting will start again. As a result, when the toner cartridge is empty, the printer will continue to print by default, thus failing to remind the user to refill the toner in time, which affects the printing quality.

[0005] In addition, the developing roller and the powder feeding roller of the toner cartridge are consumable parts. If the user can reset the detection wheel assembly after each use, the user may not be able to determine whether the developing roller and other consumable parts are damaged and continue to refill and use the toner cartridge. When the parts are damaged, the toner cartridge cannot be used normally. Since the toner has been added to the toner cartridge, this will cause waste of energy and pollution of the environment if the toner cartridge is discarded directly. SUMMARY

[0006] The first object of the present application is to provide a toner cartridge with a detection wheel assembly that can be reset and can ensure printing quality.

[0007] The second object of the present application is to provide a working method of the detection wheel assembly of the toner cartridge.

[0008] To achieve the above-mentioned first object, the present application provides a toner cartridge, comprising a cartridge body, a rotating member, a gear train and a rotating part, the cartridge body has a toner accommodating part, an end cover is arranged at the end of the cartridge body, and the rotating member is rotatably supported in the toner accommodating part; the gear train is arranged on the outer wall of the cartridge body, and the gear train is connected with the rotating member and drives the rotating member to rotate; the rotating part is rotatably installed in the accommodating space formed by the outer wall of the cartridge body and the end cover, and the rotating part is provided with a clutch wheel, the clutch wheel comprises a small-diameter part and a large-diameter part arranged in the circumferential direction, the large-diameter part is in transmission cooperation with one gear of the gear train, and the toner cartridge further comprises a reset part and a stop part, the reset part forces the rotating part to rotate, and the stop part limits the number of rotations of the clutch wheel. The reset part is located on the large-diameter part, the end cover is provided with an opening, and the reset part is exposed outside the end cover through the opening.

[0009] As can be seen from the above scheme, after the toner cartridge is installed into the printer, the gear train drives the rotating part to rotate from the detection starting position to the detection ending position, thereby completing the detection of the type and capacity of the toner cartridge, and then the printing work can be carried out. After the toner in the toner cartridge is used up, the user takes out the toner cartridge from the printer and applies a force to the reset part, the rotating part rotates to the detection starting position, so that the detection wheel assembly is reset and installed into the printer. The printer drives the gear train and drives the rotating part to rotate from the detection starting position to the detection ending position. After the printer identifies the toner cartridge as a new toner cartridge, the printer starts normal printing. At this time, the stop part blocks the rotating part from rotating to the detection starting position again. After the toner in the toner cartridge is used up again, it cannot be reset again, and the number of rotations of the clutch wheel is limited by the stop part. In this way, the toner cartridge can be refilled once, and the printing quality can be effectively guaranteed. In addition, by directly arranging the reset part on the large-diameter part of the clutch wheel, the user manually pushes the clutch wheel to reset the detection wheel assembly, which reduces the number of parts, improves the assembly efficiency and reduces the production cost.

[0010] One preferred scheme is that the toner cartridge further comprises a rotating limiting part in the shape of a ring, the rotating limiting part is rotatably installed between the clutch wheel and the end cover, and the rotating limiting part is coaxial with the clutch wheel; first and second protruding columns are respectively arranged on the opposite sides of the rotating limiting part, a first rotating groove is arranged on the clutch wheel, and a second rotating groove is arranged on the end cover, the first and second rotating grooves are coaxial with the clutch wheel, the first protruding column is in sliding cooperation with the first rotating groove, and the second protruding column is in sliding cooperation with the second rotating groove; the stop part comprises first and second stop walls, the first stop wall is arranged in the first rotating groove and can be in limiting cooperation with the first protruding column, and the second stop wall is arranged in the second rotating groove and can be in limiting cooperation with the second protruding column.

[0011] Therefore, the first convex column is limited by the first stop wall in the first rotating slot of the clutch wheel, and the second convex column is limited by the second stop wall in the second rotating slot of the end cover. Thus, the rotating member can be reset only once.

[0012] Further, the first convex column and the second convex column are arranged at intervals in the circumferential direction of the rotating limiting member.

[0013] Further, the end cover is provided with a positioning convex part, the positioning convex part protrudes from the inner surface of the end cover towards the box body, and the second rotating slot is located on the positioning convex part; the clutch wheel is provided with a limiting member installation slot, the first rotating slot is arranged on the inner wall of the limiting member installation slot, the rotating limiting member is located in the limiting member installation slot, and the end part of the positioning convex part extends into the limiting member installation slot and is adjacent to the rotating limiting member.

[0014] Therefore, the rotating limiting member is limited in the limiting member installation slot of the clutch wheel by the positioning convex part, so that the stability of the rotating limiting member installation is ensured, and the rotating limiting member is prevented from falling off.

[0015] One preferred scheme is that the rotating member is further provided with a rotating shaft, the rotating shaft is arranged on the first end surface of the clutch wheel and is coaxially arranged with the clutch wheel; a limiting protrusion is arranged on the circumferential wall of the rotating shaft, and a matching stop block is arranged on the outer wall of the box body, the matching stop block is located on the rotating path of the limiting protrusion, and the maximum distance between the limiting protrusion and the axis of the rotating shaft is slightly greater than the minimum distance between the matching stop block and the axis of the rotating shaft.

[0016] Therefore, the limiting protrusion and the matching stop block have a slight interference fit when they are opposite, so that the user can clearly perceive that the rotating member has been reset, thereby ensuring the accuracy of the reset.

[0017] One preferred scheme is that the rotating member is further provided with a rotating shaft and an elastic buckle, the rotating shaft is arranged on the first end surface of the clutch wheel and is coaxially arranged with the clutch wheel; a fixed end of the elastic buckle is connected to the circumferential wall of the rotating shaft, the outer wall of the box body is provided with a first protrusion and a second protrusion and an installation column, which protrude outward from the end wall of the box body, the first protrusion and the second protrusion are arranged at intervals along the rotating direction of the elastic buckle; the second protrusion is in the form of a broken line segment in a cross section perpendicular to the axial direction of the rotating member, the first protrusion is located above the second protrusion, and the first protrusion and the second protrusion enclose a buckle accommodation slot, the installation column is located in the middle of the buckle accommodation slot, and the rotating member is installed on the installation column; the elastic buckle is located in the buckle accommodation slot, and a free end of the elastic buckle abuts against the inner wall of the buckle accommodation slot.

[0018] Therefore, the elastic buckle is bent under stress when it is matched with the inner wall of the buckle accommodation slot, and the elastic buckle is reset under the action of the elastic restoring force of itself when the elastic buckle is rotated to the interval position between the first protrusion and the second protrusion. In this way, the user can clearly perceive that the rotating member has been reset, thereby ensuring the accuracy of the reset.

[0019] Further, the elastic buckle comprises a connecting segment and an abutting segment, the connecting segment is connected to the rotating shaft and extends along a tangent direction of the outer circumferential surface of the rotating shaft, and the abutting segment extends from one end of the connecting segment away from the rotating shaft towards the reverse direction of the rotating direction of the rotating member.

[0020] Therefore, the elastic buckle can smoothly slide along the inner wall of the buckle accommodating groove.

[0021] A preferred solution is that the rotating member is provided with a clutch wheel and a cam coaxially and out of phase, the cam is located on the second end face of the clutch wheel away from the box body; the toner cartridge further comprises a contact member, an elastic member and a reset member, the end cover is provided with an inclined wall opposite to the rotating member, the inclined wall is inclined relative to the axis of the rotating member, a second sliding groove is formed in the inclined wall, the inclination of the second sliding groove is equal to the inclination of the inclined wall relative to the axis, and the contact member is in sliding fit with the second sliding groove; the contact member has a contact end and a trigger end, the contact end is in contact with the cam, the elastic member forces the contact member to abut against one end of the second sliding groove close to the clutch wheel; the large-diameter portion is provided with an elastic friction layer in the circumferential direction, the small-diameter portion is in fit with the tooth gap of one gear in the gear train, and the large-diameter portion is in interference fit with the tooth top of the gear.

[0022] Therefore, the rotating member, the elastic member and the contact member jointly constitute a detection wheel assembly, when the detection mechanism of the printer performs detection on the toner cartridge, the rotating member starts to rotate from the position of the large-diameter portion in interference fit with the gear, drives the cam on the clutch wheel to rotate, and the cam drives the contact member to slide along the second sliding groove, when the contact member moves to the position contacted by the detection member in the printer, the trigger of the detection mechanism of the printer is completed, and the new toner cartridge and the capacity information of the toner cartridge are transmitted to the printer. When the contact member continues to move along the second sliding groove, the contact end of the contact member is out of contact with the cam, and at the same time, the rotating member rotates to the position of the small-diameter portion in fit with the gear gap, the rotating member is no longer in contact with the gear, and the rotating member stops rotating. After the contact member is out of contact with the cam, the contact member returns to the initial position under the restoring force of the elastic member.

[0023] When the toner cartridge is refilled, the user applies a force to the force applying part, the reset member drives the rotating member to continue to rotate forward along the rotating direction until the cam rotates to the initial position, the reset of the detection wheel assembly is completed, and the toner cartridge can be detected by the detection mechanism of the printer again.

[0024] Further, the rotating member is further provided with a pushing protrusion, the pushing protrusion is located at the connecting position of the small-diameter portion and the large-diameter portion and on the second end face of the clutch wheel, and in the rotating direction of the rotating member, the pushing protrusion is located on the upstream side of the small-diameter portion, and the pushing protrusion can be engaged with the gear.

[0025] Therefore, by setting the toggle protrusion, the rotating member can be prevented from slipping at the position where the rotating member starts to rotate, thereby affecting detection.

[0080] First embodiment of the toner cartridge:

[0081] Referring to Figure 1 and Figure 2 , the toner cartridge comprises a cartridge body 1, a rotating member, a gear train 3, a rotating member 4, a contact member 5, an elastic member and a reset member 7. The rotating member comprises a developing roller 21, a stirring frame 22 Figure 6 and a powder feeding roller (not shown).

[0082] The cartridge body 1 has a toner accommodating portion 10 for accommodating toner, and a driving end of the cartridge body 1 is provided with an end cover 11. The toner accommodating portion 10 has a toner outlet 101 for providing the accommodated toner outward. The developing roller 21, the powder feeding roller and the stirring frame 22 are all located in the toner accommodating portion 10 and are rotatably supported on the two end walls of the cartridge body 1, and the developing roller 21 is located at the toner outlet 101. The gear train 3 for driving the developing roller 21, the powder feeding roller and the stirring frame 22 to rotate is arranged in an accommodating space formed by the end wall of the cartridge body 1 and the end cover 11. An installation column 15 is arranged on the outer wall of the end wall of the cartridge body 1, and the rotating member 4 is rotatably installed on the installation column 15, and the rotating member 4 is arranged adjacent to one gear 31 in the gear train 3. In this embodiment, the gear 31 is a driving gear for driving the stirring frame 22 to rotate, and in other embodiments, the rotating member 4 can also be arranged adjacent to any gear in the gear train 3. The driving force received by the driving head 32 is transmitted to each rotating member and the rotating member 4 through the gear train 3.

[0083] Referring to Figures 3 to 5The rotating component 4 is provided with a clutch wheel 41, a cam 42, a rotating shaft 44 and a toggle protrusion 45. The cam 42 is located on the second end face 401 of the clutch wheel 41 on the side away from the housing 1.

[0084] The clutch wheel 41 includes a small-diameter portion 403 and a large-diameter portion 404 arranged circumferentially. The large-diameter portion 404 is provided with an elastic friction layer 411 circumferentially. When the large-diameter portion 404 of the clutch wheel 41 faces the gear 31, the elastic friction layer 411 is interference-fitted with the gear 31, and the gear 31 drives the rotating component 4 to rotate through friction. When the small-diameter portion 403 of the clutch wheel 41 faces the gear 31, the small-diameter portion 403 is clearance-fitted with the tooth tip of the gear 31, so that the rotating component 4 cannot be driven by the gear 31 and thus stops rotating. In this embodiment, the elastic friction layer 411 is an elastic rubber ring made of rubber or other materials covering the large-diameter portion 404.

[0085] The cam 42 includes a protrusion 421 and a rotating shaft 422. The cam 42 and the clutch wheel 41 are coaxial but staggered in phase, that is, the rotating shaft 422 and the clutch wheel 41 are arranged along the same axis, and the protrusion 421 of the cam 42 and the large-diameter portion 404 of the clutch wheel 41 are not in the same position in the direction perpendicular to the axial direction. Figure 2 As shown, the contact member 5 has a contact end 51 and a trigger end 52. The contact end 51 can contact the cam 42, and the trigger end 52 is used to trigger the detection mechanism of the printer.

[0086] like Figure 1 and Figure 2 As shown, a planar inclined wall 111 is provided at the position opposite to the rotating member 4 on the end cap 11. The inclined wall 111 is inclined relative to the axis of the rotating member 4. A second sliding groove 112 is provided on the inclined wall 111. The inclination of the second sliding groove 112 to the axis is equal to the inclination of the inclined wall 111 to the axis. The contact member 5 slides in cooperation with the second sliding groove 112.

[0087] The elastic element is a torsion spring 6, which is installed on the inner wall of the end cover 11 facing the clutch wheel 41. The torsion spring 6 forces the contact member 5 to abut against one end 1121 of the second slide groove 112 along the axial direction of the rotating member 4, close to the clutch wheel 41.

[0088] The reset component 7 is movably mounted on the outer wall of the housing 1 and located between the rotating component 4 and the housing 1. The reset component 7 has a first sliding groove 75 on the side facing the housing 1. A slide rail 12 is provided on the outer wall of the housing 1. The slide rail 12 is slidably engaged with the first sliding groove 75. The extension direction of the slide rail 12 is perpendicular to the axial direction of the rotating component 4. An outwardly protruding arrow mark 113 is provided on the upper surface of the end cover 11 near the slide rail 12 to help the user understand the pushing direction of the reset component 7.

[0089] See Figures 6 to 8The reset member 7 includes a force applying part 71, a reset part 72, a pushing part 764, a first limiting part 77 and a second limiting part 78. The end cover 11 is provided with an opening. The force applying part 71 is exposed outside the end cover 11 through the opening, so as to facilitate manual operation of a user. An upper surface of the force applying part 71 is provided with an anti-skid protrusion 73 and a buckle protrusion 74. In the sliding direction of the reset member 7, the buckle protrusion 74 is arranged on the upstream side of the reset member 7. As shown in Figure 9 FIG. 6, the highest point A1 of the buckle protrusion 74 is higher than the highest point A2 of the anti-skid protrusion 73.

[0090] The reset member 7 is provided with a containing groove 76 on the side facing the rotating member 4. The rotating member 4 is provided with a force receiving protrusion 43 on the first end face 402 of the side facing the box body 1. The force receiving protrusion 43 is located on the first end face 402 of the side of the clutch wheel 41 close to the box body 1. The force receiving protrusion 43 protrudes outward along the axial direction of the rotating member 4 from the first end face 402 and can enter the containing groove 76 in the detection process. The containing groove 76 is provided with a first side wall 761 and a second side wall 762 on the opposite sides in the sliding direction X of the reset member 7. The second side wall 762 is located on the downstream side of the first side wall 761.

[0091] The reset part 72 is located on the side of the first side wall 761 of the containing groove 76 facing the containing groove 76. The force receiving protrusion 43 is provided with a force receiving part 431 and a stop part 432 on the opposite side walls. When the force receiving protrusion 43 is located in the containing groove 76, the force receiving part 431 is opposite to the reset part 72. In the process of the reset part 72 pushing the rotating member 4 to reset, the reset part 72 is located on the upstream side of the force receiving part 431 in the rotating direction R of the rotating member 4. The bottom of the first side wall 761 is provided with an arc-shaped guide face 763, which facilitates the force receiving protrusion 43 to smoothly enter the containing groove 76.

[0092] The first limiting part 77 is located on the side of the first side wall 761 away from the containing groove 76. The second limiting part 78 is located on the side of the second side wall 762 facing the containing groove 76. The stop part 432 is located on the side of the force receiving protrusion 43 away from the force receiving part 431. The first limiting part 77, the second limiting part 78 and the stop part 432 cooperate to limit the number of rotations of the clutch wheel 41. The pushing part 764 is located on the side of the second side wall 762 away from the containing groove 76.

[0093] The rotating shaft 44 is mounted on the first end face 402 of the clutch wheel 41 and is coaxial with the clutch wheel 41. A limiting protrusion 441 is provided on the peripheral wall of the rotating shaft 44, and a mating block 13 is provided on the outer wall of the housing 1. The mating block 13 is located on the rotation path of the limiting protrusion 441. The maximum distance between the limiting protrusion 441 and the axis of the rotating shaft 44 is slightly greater than the minimum distance between the mating block 13 and the axis of the rotating shaft. In this way, when the limiting protrusion 441 and the mating block 13 are opposite each other, they are in an interference fit, which allows the user to clearly perceive that the rotating part 4 has been reset to the initial position.

[0094] The actuating protrusion 45 is located at the connection position between the small diameter portion 403 and the large diameter portion 404 and is located on the second end face 401 of the clutch wheel 41. In the rotation direction R of the rotating member 4, the actuating protrusion 45 is located on the upstream side of the small diameter portion 403, and the actuating protrusion 45 can mesh with the gear 31.

[0095] The contact end 51 of the contact member 5 extends to the second end face 401 of the clutch wheel 41. The distance between the end face 4211 of the protrusion 421 on the cam 42 and the end 1122 of the second slide groove 112 away from the clutch wheel 41 in the axial direction of the rotating member 4 is greater than the distance between the contact end 51 and the end 1122 of the second slide groove 112 away from the clutch wheel 41 in the axial direction of the rotating member 4. This makes it easier for the contact member 5 to slide a certain distance along the second slide groove 112 and then disengage from the protrusion 421.

[0096] Rotating component 4, torsion spring 6, and contact component 5 together constitute the detection wheel assembly, such as Figure 9 As shown, when the toner cartridge is assembled and tested in the factory, the rotating part 4 is in the position where the small diameter part 403 faces the gear 31. During the test, the rotating part 4 does not rotate. After the test, the worker pushes the reset part 7 along the X direction, and the pushing part 764 pushes the force-bearing protrusion 43 to force the rotating part 4 to rotate along the R direction. Figure 10 As shown, when the limiting protrusion 441 and the mating stop 13 are opposite each other, they are in an interference fit, allowing the worker to clearly perceive that the rotating part 4 has been pushed to the detection starting position. At this time, the large-diameter part 404 and the gear 31 are in an interference fit. Then, it can be packaged and sold.

[0097] When the user installs the toner cartridge into the printer and the test wheel assembly is working, if... Figure 2 , Figures 10 to 12 When the printer's testing mechanism performs testing on the toner cartridge, the rotating part 4 starts from the initial testing position where its large diameter portion 404 is interference-fitted with the gear 31. Figure 9When the contact member 5 moves to the position where the detection member in the printer contacts, the triggering of the detection mechanism of the printer is completed, and the information such as the newness of the toner cartridge and the capacity of the toner cartridge is transmitted to the printer. When the contact member 5 continues to move along the second sliding groove 112, the contact end 51 of the contact member 5 is out of contact with the cam 42, and at the same time, the rotating member 4 rotates to the position where the small-diameter portion 403 is in clearance fit with the gear 31, the rotating member 4 is no longer in contact with the gear 31, and the rotating member 4 stops rotating. After the contact member 5 is out of contact with the cam 42, the contact member 5 returns to the initial position under the action of the restoring force of the torsion spring 6. At the same time, the stress protrusion 43 rotates with the rotating member 4 and enters the accommodating groove 76.

[0098] When the toner in the toner cartridge is used up, the user adds toner to the toner cartridge, and as shown in Figure 13 and 14 , the user applies a force F to the force applying portion 71 of the reset member 7, forces the reset portion 72 to push the stress protrusion 43 and drives the rotating member 4 to continue rotating in the rotating direction R, until the limiting protrusion 441 of the cam 42 passes the cooperating stop block 13, and the user can clearly perceive that the reset is completed, at this time, as shown in Figure 14 , the rotating member 4 rotates to the detection initial position, the reset of the detection wheel assembly is completed, and the toner cartridge can be detected by the detection mechanism of the printer again.

[0099] When the user puts the toner cartridge into the printer again, after the detection wheel assembly of the toner cartridge triggers the detection mechanism of the printer, the rotating member rotates to the position shown in Figure 15 , at this time, the first limiting portion 77 limits and blocks on the downstream side of the rotating path of the stress protrusion 43, so the rotating member 4 cannot be reset again. At the same time, in the detection initial position shown in Figure 14 , that is, the reset end position, because the first limiting portion 78 cooperates with the stop portion 432 of the stress protrusion 43 to block, the user cannot push the reset member in the reverse direction of the X direction to reset to the position shown in Figure 10 . Therefore, the user can reset the detection wheel assembly only once, compared with the prior art, through limited times of reset, the printing quality is effectively ensured. In addition, because the toner cartridge of the present application needs to be manually reset, when the printer is taken out from the printer due to paper jam and other faults and then put into the printer, because the detection wheel assembly is not reset, the printer recognizes the toner cartridge as an old cartridge, and continues to count as before, so the printer can accurately remind the user whether there is toner in the toner cartridge, thereby effectively ensuring the printing quality.

[0100] Second embodiment of the toner cartridge:

[0101] As a description of the second embodiment of the toner cartridge of the present application, only the differences from the first embodiment of the toner cartridge described above will be described below.

[0104] When the detection wheel assembly is working, the force receiving portion 243 on the rotating member 240 rotates counterclockwise and pushes the reset portion 272, the reset portion 272 rotating clockwise around the hinged portion 273 to reset after avoiding. In addition, after refilling twice, the user presses the force applying portion 271, the reset member 27 rotates clockwise around the hinged portion 273, the reset portion 272 pushes the force receiving portion 243 of the rotating member 240 upward, forcing the rotating member 240 to rotate to the initial position of detection, completing the reset of the detection wheel assembly. At the same time, the guide surface 2751 guides the clamping protrusion 216 to slide into the clamping hook 275 to limit the reset member 27, ensuring that the user can reset the detection wheel assembly only once.

[0105] The third embodiment of the toner cartridge:

On the rotation path of the limiting portion 377, the guide wall 4323 is located on the upstream side of the stop wall 4324. The sliding fit wall 3771 is in sliding fit with the guide wall 4323, and the limiting wall 3772 is in limiting fit with the stop wall 4324. The limiting of the limiting teeth 4321 ensures that the reset member 37 can only rotate in the direction of the arrow R1.

[0110] The rotating member 340 further has a rotating shaft 344 and an elastic buckle 345. The rotating shaft 344 is arranged on the first end face of the clutch wheel 341 and is coaxially arranged with the clutch wheel 341. The fixed end 3451 of the elastic buckle 345 is connected to the peripheral wall of the rotating shaft 344. The elastic buckle 345 includes an obtuse angle arranged connecting segment 3453 and an abutting segment 3454. The connecting segment 3453 is connected to the peripheral wall of the rotating shaft 344 and extends in a direction tangent to the outer peripheral surface of the rotating shaft 344. The abutting segment 3454 extends from the end of the connecting segment 3453 away from the rotating shaft 344 towards the opposite direction of the rotating direction of the rotating member 340.

The elastic buckle 345 is located in the buckle accommodating groove 315, and the free end 3452 of the elastic buckle 345 abuts against the inner wall of the buckle accommodating groove 315.

[0112] When the carbon powder cartridge in the embodiment is assembled and tested in the factory, as shown in Figure 24 , the rotating piece 340 is in a position where the large-diameter portion 3404 is in interference fit with the gear 331, and during the testing process, the rotating piece 340 is rotated from the Figure 24 position to the Figure 25 position. After the testing is completed, a worker manually pushes the rotating piece 340 in the direction indicated by the arrow R2 to the Figure 26 position, and then pushes the force applying part 371 of the reset piece 37 in the direction indicated by the arrow R1, and the second tooth part 3721 of the reset piece 37 is rotated to a position where it is circumferentially adjacent to the first tooth part 3432, that is, from the position of the reset piece 37 indicated by the solid line in Figure 26 to the position of the reset piece 37 indicated by the dashed line. Then, it can be packaged and sold.

[0113] When the user installs the carbon powder cartridge into the printer, during the operation of the detection wheel assembly, the rotating piece 340 is rotated from the initial position where the large-diameter portion 3404 is in interference fit with the gear 331 (the position indicated by Figure 26 ) to the position where the small-diameter portion 3403 is in clearance fit with the gear 331 (the position indicated by Figure 27 ), and the rotating piece 340 is no longer in contact with the gear 331, and the rotating piece 340 stops rotating. During the rotation, the large-diameter portion 3404 of the rotating piece 340 intermittently presses the detection mechanism in the printer, and the triggering of the detection mechanism of the printer is completed.

[0114] When the carbon powder in the carbon powder cartridge is used up, after the user refills the carbon powder cartridge, as shown in Figure 27 and Figure 28 , the user applies a force to the reset piece 37, and the reset piece 37 rotates about the hinge part 373, at this time, the second tooth part 3721 of the reset piece 37 is engaged with the first tooth part 3432 and drives the rotating piece 340 to rotate forward along the rotation direction R2 to the detection initial position indicated by Figure 28 , and the reset of the rotating piece 340 is completed. During this process, the elastic buckle 345 is rotated from the Figure 30 position to theFigure 31 When the free end 3452 of the elastic buckle 345 is disengaged from the inner wall of the buckle accommodating groove 315, the elastic buckle 345 is reset under the action of the elastic restoring force, so that the user can clearly perceive that the resetting is completed.

[0115] After the user installs the toner cartridge into the printer again, the detection wheel assembly of the toner cartridge rotates the rotating member 340 to the position shown in the figure after triggering the detection mechanism of the printer. Figure 29 At this time, the second tooth part 3721 of the resetting member 37 rotates to the downstream side of the rotating path of the first tooth part 3432, and the limiting part 377 of the resetting member 37 is limited by the limiting tooth 4321, so that the resetting member 37 cannot rotate in the reverse direction of the arrow R1, and the user cannot reset the detection wheel assembly again.

[0116] In addition, in this embodiment, after the factory completes the test, the worker can also disassemble the end cover and reset the drive gear, the resetting member and the rotating member to the position shown in the figure, so that the user can reset the detection wheel assembly twice, but the two resetting methods are different. Figure 24

[0117] Toner cartridge fourth embodiment:

[0118] As an illustration of the fourth embodiment of the toner cartridge of the present application, only the differences from the third embodiment of the toner cartridge described above will be described below.

[0119] Referring to Figures 32 to 36 In this embodiment, the toner cartridge is not provided with a separate resetting member, and the resetting part 472 of the detection wheel assembly is located on the large-diameter part 4404 of the rotating member 440, and the resetting part 472 can be exposed outside the end cover 4110 through the second opening 41101. The outward end face of the large-diameter part 4404 is provided with an outwardly protruding arrow mark 413, which facilitates the user to understand the direction of pushing the rotating member 440 during resetting.

[0120] ​The detection wheel assembly comprises a rotating member 440 and a circular rotating limiting member 8. The rotating limiting member 8 is rotatably installed between the clutch wheel 4410 and the end cover 4110, and is coaxial with the clutch wheel 4410. The opposite sides of the rotating limiting member 8 are respectively provided with a first protruding column 81 and a second protruding column 82, which are arranged at intervals in the circumferential direction of the rotating limiting member 8. The clutch wheel 4410 is provided with a circular first rotating groove 4411, and the end cover 4110 is provided with a circular second rotating groove 4111. The first rotating groove 4411 and the second rotating groove 4111 are coaxial with the clutch wheel 4410. The first protruding column 81 is in sliding fit with the first rotating groove 4411, and the second protruding column 82 is in sliding fit with the second rotating groove 4111. The stop portion comprises a first stop wall 83 and a second stop wall 84. The first stop wall 83 is arranged in the first rotating groove 4411 and can be in limiting fit with the first protruding column 81. The second stop wall 84 is arranged in the second rotating groove 4111 and can be in limiting fit with the second protruding column 82.

[0121] The end cover 4110 is provided with a positioning protrusion 4112, which protrudes from the inner surface of the end cover 4110 towards the box body 410. The second rotating groove 4111 is located on the positioning protrusion 4112. The clutch wheel 4410 is provided with a limiting member installation groove 4413. The first rotating groove 4411 is arranged on the inner wall of the limiting member installation groove 4413. The rotating limiting member 8 is located in the limiting member installation groove 4413. The end of the positioning protrusion 4112 extends into the limiting member installation groove 4413 and abuts against the rotating limiting member 8. The structure of the elastic buckle 345 is in elastic contact with the inner wall of the buckle containing groove 415, and can prevent the user from rotating the rotating member 440 in the reverse direction.

[0122] Figures 37 to 40 The position relationship diagram of the carbon powder box before the detection wheel assembly works. Figures 41 to 44 The position relationship diagram of the carbon powder box when the first detection work of the detection wheel assembly ends. Figures 45 to 48 The position relationship diagram of the carbon powder box after resetting. Figures 49 to 52 The position relationship diagram of the carbon powder box when the second detection work ends.

[0123] After the user installs the carbon powder box into the printer, the detection wheel assembly starts to work, and the rotating member 440 rotates from the initial large-diameter part 4404 in interference fit with the gear 4310 to the small-diameter part 4403 in clearance fit with the gear 4310. Figure 37 Figure 41 Figures 37 to 39 ​​As shown, the first convex column 81 is located on the upstream side of the first blocking wall 83 and close to the first blocking wall 83, at this time, when the gear 4310 drives the rotating member 440 to rotate, the rotating limiting member 8 can not rotate, can rotate together with the rotating member 440, or can rotate at times and not at times, in this embodiment, the rotating limiting member 8 is taken as an example to be described together with the rotating member 440. When the rotating member 440 and the rotating limiting member 8 rotate together around the center axis of the mounting column 414, the second convex column 82 rotates along the second rotating groove 4111. When the detection is completed, as shown in Figures 41 to 43 As shown, the first convex column 81 is still located on the upstream side of the first blocking wall 83 and close to the first blocking wall 83, at this time, the second convex column 82 rotates to a position close to the second blocking wall 84, at this time, the second blocking wall 84 is located on the downstream side of the second convex column 82.

[0124] When the toner in the toner cartridge is used up, the user adds toner to the toner cartridge, and then applies force to the reset part 472 to push the rotating member 440 in the direction of the arrow mark 413, and the rotating member 440 is reset from the detection end position shown in Figure 41 to the detection start position shown in Figure 45 , the elastic buckle 445 rotates from the position shown in Figure 44 to the position shown in Figure 48 , and the user can feel that the reset is completed. During the reset process, when the second convex column 82 rotates to the position of contacting the second blocking wall 84, the second convex column 82 cannot rotate along the second rotating groove 4111 any more due to the limitation of the second blocking wall 84, that is, the rotating limiting member 8 is fixed relative to the end cover 4110. When the rotating member 440 continues to rotate forward, the first blocking wall 83 begins to move away from the first convex column 81 until it rotates to Figure 47 the position shown in, and the reset is completed.

[0125] After the user puts the toner cartridge into the printer again, the detection wheel assembly of the toner cartridge triggers the detection mechanism of the printer, and then the rotating member 440 rotates to Figure 49 the position shown in, at this time, in the direction of rotation, the first convex column 81 is located on the downstream side of the first blocking wall 83 and limits the first blocking wall 83, and the rotating member 440, the rotating limiting member 8 and the end cover 4110 form a limiting fit, so that the user cannot reset the detection wheel assembly again.

[0126] Finally, it should be emphasized that the above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
