Description

Technical Field

[0001] The invention relates to the technical field of electronic photographic imaging, in particular to a toner cartridge and a printer provided with the toner cartridge. Background Art

[0002] Existing toner cartridges are all equipped with a detection component to cooperate with the detection mechanism on the printer to detect the toner cartridge after it is installed on the printer, such as detecting whether the toner cartridge is used for the first time, the type of toner cartridge, the capacity of the toner cartridge, whether the toner cartridge is installed in place, etc. Among them, the toner cartridge mainly includes a box body, a stirring frame, a powder feeding roller, a developing roller and a power receiving head, and the detection component mainly includes a detection wheel. The stirring frame is rotatably mounted in the powder bin of the box body, and a stirring frame gear is provided at the first end of the stirring frame, and the stirring frame gear is located outside the powder bin and at the first end wall of the box body; the powder feeding roller is rotatably mounted in the powder bin and at the powder outlet of the powder bin, and a powder feeding roller gear is provided at one end of the powder feeding roller, and the powder feeding roller gear is located outside the powder bin and at the first end wall of the box body; the developing roller is rotatably mounted on the box body, and the developing roller is located outside the powder bin and at the powder outlet, and the developing roller is adjacent to the powder feeding roller, and a developing roller gear is provided at one end of the developing roller and is located at the first end wall; the power receiving head is used to connect with the driving head on the printer so that the driving head can drive the power receiving head to rotate, and the power receiving head is rotatably mounted on the first end wall, and a first gear structure is provided on the power receiving head, and the powder feeding roller gear and the developing roller gear are respectively meshed with the first gear structure, so that the first gear structure drives the powder feeding roller gear and the developing roller gear to rotate in opposite directions, and the stirring frame gear and the first gear structure are linked by an idler gear. The detection wheel can be rotatably arranged on the first end wall or the second end wall of the box body as needed, and the detection wheel and the power receiving head can be directly or indirectly linked. For example, when the detection wheel is arranged on the first end wall, the detection wheel can be directly engaged with the first gear structure or engaged with the first gear structure through a gear set; when the detection wheel is arranged on the second end wall, a transmission gear can be arranged at the second end of the stirring frame, and the transmission gear can be engaged with the second gear structure on the detection wheel, or a rubber ring can be arranged on the detection wheel, and the rubber ring can be frictionally linked with the transmission gear.

[0003] When the toner cartridge is installed in the printer for the first time, the detection component contacts the detection mechanism of the printer. Then, the drive 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 to a preset angle, the detection mechanism performs a detection on the detection component to determine whether the toner cartridge is used for the first time, the type of the toner cartridge, the capacity of the toner cartridge, etc. After completing this detection, the detection wheel is no longer driven by the power receiving head and the transmission mechanism, and the retaining component in the toner cartridge fixes the detection wheel that has completed the detection work, so that the printer can detect the presence of the toner cartridge when the toner cartridge is installed next time.

[0004] However, existing toner cartridges have the following disadvantages:

[0005] First, when the second gear structure is set on the detection wheel, the structural complexity and production cost of the detection wheel are increased. In addition, when the power receiving head is driven by the driving head of the printer, it not only drives the stirring frame gear, the powder feeding roller gear and the developing roller gear to rotate, but also drives the detection wheel to rotate. Therefore, after a series of rotational transmissions, the rotational distortion force and torque exerted on the driving force receiving head will be very large, causing the power receiving head and the driving head of the printer to be easily damaged, especially when the detection wheel and the driving force receiving head are linked through a gear set, which will further accelerate the damage of the power receiving head and the driving head.

[0006] Second, when a rubber ring is provided on the detection wheel, although the structure and production cost of the detection wheel can be simplified, the rubber ring is prone to slip when the detection wheel is driven, resulting in the inability of the power receiving head or the transmission gear to reliably drive the detection wheel to rotate, thereby causing the printer to be unable to accurately identify the toner cartridge. Summary of the invention

[0007] In order to solve the above problems, the main purpose of the present invention is to provide a toner cartridge with a simple structure, low production cost and the ability to appropriately reduce the torque on the power receiving head.

[0008] Another object of the present invention is to provide a printer provided with the above-mentioned toner cartridge.

[0009] In order to achieve the main purpose of the present invention, the present invention provides a toner cartridge, including a box body and a stirring frame, a detection wheel is arranged on the first end wall of the box body, the stirring frame is rotatably installed inside the box body, a transmission wheel is arranged outside the box body at the first end of the stirring frame, and the transmission wheel is located at the first end wall, wherein the toner cartridge also includes a flexible belt, the flexible belt is wound between the transmission wheel and the detection wheel, and the flexible belt can drive the detection wheel to rotate to a preset angle under the winding of the transmission wheel and then disconnect from the detection wheel.

[0010] As can be seen from the above, the flexible belt is wound between the transmission wheel and the detection wheel, so that the transmission wheel can drive the detection wheel to rotate through the flexible belt, and then the detection mechanism on the printer can detect the toner cartridge through the detection wheel; and because the detection wheel is only used once in a life cycle of the toner cartridge, the transmission wheel and the detection wheel are connected by the flexible belt, and the detection wheel is disconnected from the flexible belt after rotating a preset angle, which can ensure that the detection wheel is only driven once, so as to avoid the detection mechanism of the printer from detecting the toner cartridge multiple times in a life cycle of the toner cartridge, thereby preventing the printer from misjudging or misjudging the use status of the toner cartridge. In addition, the structural design of the toner cartridge can also effectively reduce the production cost of the toner cartridge, simplify the structure of the toner cartridge, and appropriately reduce the torque on the power receiving head, and protect the drive head of the printer.

[0011] A preferred solution is that the rotation direction of the transmission wheel is opposite to the rotation direction of the detection wheel.

[0012] As can be seen from the above, the transmission wheel and the detection wheel are connected by a flexible belt, so that the relative rotation direction of the transmission wheel and the detection wheel can be changed by different winding methods of the flexible belt between the transmission wheel and the detection wheel. Preferably, the flexible belt can be wound in a serpentine shape between the transmission wheel and the detection wheel, so that the transmission wheel and the steering direction of the detection wheel are opposite.

[0013] Another preferred scheme is that the detection wheel has an arc surface or a first cylindrical surface, the axis of the arc surface or the axis of the first cylindrical surface is collinear with the rotation axis of the detection wheel, and the initial center angle of the flexible belt wrapped on the arc surface or the first cylindrical surface is 130° to 170°; and / or the transmission wheel has a second cylindrical surface, the axial direction of the second cylindrical surface is collinear with the rotation axis of the transmission wheel, and the initial length of the flexible belt wrapped on the second cylindrical surface is 0.4 times to 2 times the circumference of the second cylindrical surface.

[0014] As can be seen from the above, the shape and structure of the mating surface between the detection wheel and the flexible belt can be adjusted according to the production process, production cost and design requirements, and the initial center angle of the flexible belt wrapped around the detection wheel can be set according to the preset angle of rotation required for the detection wheel; and the mating surface between the transmission wheel and the flexible belt is set as a cylindrical surface, which can enable the transmission wheel to drive the detection wheel to rotate at a uniform speed through the flexible belt, so as to ensure the accuracy of the printer's detection mechanism in detecting the toner cartridge. In addition, by designing the initial length of the flexible belt wrapped around the transmission wheel, the transmission wheel can reliably drive the detection wheel to rotate through the flexible belt, and prevent the flexible belt from falling off the transmission wheel when the transmission wheel winds the flexible belt.

[0015] A further solution is that the minimum distance between the arc surface and the second cylindrical surface is 2 to 6 times the thickness of the flexible belt; or the minimum distance between the first cylindrical surface and the second cylindrical surface is 2 to 6 times the thickness of the flexible belt.

[0016] As can be seen from the above, the above design can ensure that when the flexible belt is detached from the connection with the detection wheel and is completely wound onto the transmission wheel, the flexible belt does not contact the detection wheel, thereby preventing the flexible belt from continuing to drive the detection wheel to rotate through friction, thereby avoiding the printer's detection mechanism from misdetecting or erroneously detecting the toner cartridge.

[0017] In a further embodiment, the thickness of the flexible belt is 0.5 mm to 3 mm.

[0018] As can be seen from the above, the thickness of the flexible belt can be selected according to the material of the flexible belt to avoid plastic deformation of the flexible belt due to tension during use, thereby ensuring the rotation stability and rotation reliability of the detection wheel when it is rotated.

[0019] A further solution is that the end of the flexible belt on the detection wheel is bonded to the arc surface or the first cylindrical surface, the flexible belt is bonded to the second cylindrical surface, and the bonding force between the flexible belt and the detection wheel is smaller than the bonding force between the flexible belt and the transmission wheel.

[0020] As can be seen from the above, the flexible belt is bonded to the detection wheel and the transmission wheel respectively, so that the flexible belt can be peeled off from the detection wheel and the transmission wheel respectively, thereby facilitating the recycling of the toner cartridge. Making the adhesion between the flexible belt and the detection wheel smaller than the adhesion between the flexible belt and the transmission wheel ensures that when the transmission wheel drives the detection wheel to rotate through the flexible belt, the flexible belt can be detached from the detection wheel without being detached from the transmission wheel.

[0021] A further solution is that a side of the flexible belt facing away from the detection wheel is coated with adhesive.

[0022] As can be seen from the above, adhesive is coated on the side of the flexible belt facing away from the detection wheel, so that when the flexible belt is detached from the detection wheel, the flexible belt can be completely wound onto the transmission wheel when the transmission wheel winds up the flexible belt, thereby preventing the flexible belt from escaping from the end of the detection wheel and affecting the operation of other transmission components of the toner cartridge.

[0023] In a further embodiment, the flexible belt is made of polyvinyl chloride, polyurethane, polyethylene, polypropylene or nylon.

[0024] As can be seen from the above, the material for making the flexible belt can be selected appropriately according to the use requirements, production requirements, cost, and installation space factors.

[0025] In order to achieve the main purpose of the present invention, the toner cartridge provided by the present invention may also include a box body, a power receiving head and a detection wheel are arranged on the first end wall of the box body, wherein the toner cartridge also includes a flexible belt, the flexible belt is wound between the power receiving head and the detection wheel, and the flexible belt can drive the detection wheel to rotate to a preset angle under the winding of the power receiving head and then disconnect from the detection wheel.

[0026] As can be seen from the above, the flexible belt is wound between the power receiving head and the detection wheel, so that the power receiving head can directly drive the detection wheel to rotate through the flexible belt, and then the detection mechanism on the printer can detect the toner cartridge through the detection wheel. Since the detection wheel is only used once in a life cycle of the toner cartridge, the power receiving head and the detection wheel are connected by the flexible belt, and the detection wheel is disconnected from the flexible belt after rotating a preset angle, which can ensure that the detection wheel is only driven once, so as to avoid the detection mechanism of the printer from detecting the toner cartridge multiple times in a life cycle of the toner cartridge, thereby preventing the printer from misjudging or misjudging the practical status of the toner cartridge. In addition, the structural design of the toner cartridge can also effectively reduce the production cost of the toner cartridge, simplify the structure of the toner cartridge, and appropriately reduce the torque on the power receiving head, and protect the drive head of the printer.

[0027] In order to achieve another object of the present invention, the present invention provides a printer, which includes the above-mentioned toner cartridge.

[0028] It can be seen from the above that the printer provided with the above-mentioned toner cartridge can ensure the detection accuracy of the toner cartridge, and can better avoid damage to the drive head, and can also reduce the use cost of the toner cartridge.

[0036] Toner cartridge first embodiment:

[0037] Reference Figure 1 and Figure 2 The toner cartridge 100 comprises a cartridge body 1, a stirring frame 2, a flexible belt 3, a powder feeding roller 3 and a developing roller 4. A powder bin 11 is provided inside the cartridge body 1, and the powder bin 11 is used to store toner. A detection wheel 12 is provided on the first end wall of the cartridge body 1, and the detection wheel 12 can rotate around its own axis. A power receiving head 13 and an idler wheel 14 are provided on the second end wall of the cartridge body 1, and the power receiving head 13 can rotate relative to the cartridge body 1 around its own axis, and the idler wheel 14 can rotate relative to the cartridge body 1 around its own axis. When the toner cartridge 100 is installed in the cartridge bin of the printer, the power receiving head 13 is connected to the driving head of the printer, so that the driving head of the printer can drive the power receiving head 13 to rotate, and then drive the stirring frame 2, the powder feeding roller 3 and the developing roller 4 to rotate through the transmission system of the toner cartridge 100, and the detection wheel 12 is connected to the detection head of the printer, so that the detection mechanism of the printer detects the toner cartridge 100 through the detection wheel 12 to obtain parameter information of the toner cartridge 100.

[0038] In addition, the toner cartridge 100 is provided with a powder filling port 15 at the second end wall, and the powder filling port 15 is connected to the powder bin 11, so that the user can add toner into the box body 1 through the powder filling port 15 to meet the recycling requirements of the toner cartridge 100; a powder port cover 16 is detachably mounted on the powder filling port 15, and the powder port cover 16 can close the powder filling port 15 to prevent the toner in the powder bin 11 from leaking out of the box body 1 from the powder filling port 15 during the use or transportation of the toner cartridge 100. When it is necessary to add toner to the powder bin 11, the powder port cover 16 is removed from the powder filling port 15, and after completing the powder filling process of the powder bin 11, the powder port cover 16 is covered on the powder filling port 15 again.

[0039] Combination Figure 3 The driving force receiving head 13 is provided with a first gear 131, a second gear 132 and a clamping portion 133, wherein the first gear 131, the second gear 132 and the clamping portion 133 are integrally formed. The clamping portion 133 is used to clamp with the driving head of the printer so that the driving head of the printer can reliably drive the power receiving head 13 to rotate.

[0040] Combination Figure 4The stirring frame 2 is rotatably mounted on the box body 1, the main body of the stirring frame 2 is located in the powder bin 11, and the two axial ends of the stirring frame 2 extend out of the first end wall and the second end wall respectively. The idler wheel 14 is provided with a third gear 141 and a fourth gear, and the third gear 141 is meshed with the first gear 131 of the power receiving head 13. The second end of the stirring frame 2 is provided with a stirring frame gear, the stirring frame gear is located at the second end wall of the box body 1, and the stirring frame gear is meshed with the fourth gear of the idler wheel 14, so that the driving force receiving head 13 can drive the stirring frame 2 to rotate through the idler wheel 14 to stir the carbon powder in the powder bin 11, thereby preventing the carbon powder in the powder bin 11 from solidifying into a block, and improving the powder feeding quality of the powder feeding roller 3. A transmission wheel 21 is provided at the first end of the stirring frame 2, and the transmission wheel 21 is fixedly connected to the stirring frame 2, and the transmission wheel 21 is located at the first end wall of the box body 1, and the transmission wheel 21 is connected to the detection wheel 12 by a flexible belt 3, so that the stirring frame 2 can drive the detection wheel 12 to rotate through the transmission wheel 21 and the flexible belt 3, and then the detection mechanism of the printer can detect the toner cartridge 100 through the detection wheel 12, such as detecting whether the toner cartridge 100 is used for the first time, the type of the toner cartridge 100, the capacity of the toner cartridge 100, etc.

[0041] Combination Figure 5 and Figure 6 The flexible belt 3 is wound between the transmission wheel 21 and the detection wheel 12, so that the flexible belt 3 can be disconnected from the detection wheel 12 after the detection wheel 12 is driven to rotate to a preset angle under the winding of the transmission wheel 21. In this embodiment, the flexible belt 3 is wound between the transmission wheel 21 and the detection wheel 12 in a serpentine shape, so that the rotation direction of the transmission wheel 21 is opposite to the rotation direction of the detection wheel 12.

[0042] The detection wheel 12 has an arc surface 121, and the axis of the arc surface 121 is colinear with the rotation axis of the detection wheel 12, and the initial center angle a of the flexible belt 3 wrapped around the arc surface 121 of the detection wheel 12 is preferably 130° to 170°, wherein the specific angle value of the initial center angle a of the flexible belt 3 wrapped around the arc surface 121 of the detection wheel 12 can be appropriately set according to the structure, detection method and detection requirements of the detection mechanism of different printers, so they are not listed one by one here.

[0043] The transmission wheel 21 has a second cylindrical surface 211, the axial direction of the second cylindrical surface 211 is colinear with the rotation axis of the transmission wheel 21, and the initial length of the flexible belt 3 wound on the second cylindrical surface 211 is preferably 0.4 to 2 times the circumference of the second cylindrical surface 211. The matching surface of the transmission wheel 21 and the flexible belt 3 is set as a cylindrical surface so that the transmission wheel 21 can drive the detection wheel 12 to rotate at a uniform speed through the flexible belt 3 to ensure the accuracy of the detection structure of the printer on the toner cartridge 100. In addition, by designing the initial length of the flexible belt 3 wound on the transmission wheel 21, the transmission wheel 21 can reliably drive the detection wheel 12 to rotate through the flexible belt 3, while preventing the flexible belt 3 from falling off the transmission wheel 21 when the transmission wheel 21 winds the flexible belt 3.

[0044] The first end of the flexible belt 3 is bonded to the arc surface 121 of the detection wheel 12. Preferably, the end of the flexible belt 3 on the detection wheel 12 is bonded to the arc surface 121, that is, only the end of the first end of the flexible belt 3 is bonded to the detection wheel 12. In addition, the second end of the flexible belt 3 is bonded to the second cylindrical surface 211 of the transmission wheel 21. Preferably, the overlapping part of the flexible belt 3 and the second cylindrical surface 211 is entirely coated with adhesive, so as to prevent the flexible belt 3 from falling off the transmission wheel 21. The adhesive force between the flexible belt 3 and the detection wheel 12 is smaller than the adhesive force between the flexible belt 3 and the transmission wheel 21, so that when the transmission wheel 21 drives the detection wheel 12 to rotate through the flexible belt 3, the flexible belt 3 will not fall off the transmission wheel 21, and the flexible belt 3 can drive the detection wheel 12 to rotate with the transmission wheel 21, and disengage from the detection wheel 12 after rotating to a preset angle. In addition, the side of the flexible belt 3 facing away from the detection wheel 12 is coated with adhesive. By coating the adhesive on the side of the flexible belt 3 facing away from the detection wheel 12, when the flexible belt 3 is detached from the detection wheel 12, the flexible belt 3 can be completely wound onto the transmission wheel 21 when the transmission wheel 21 winds up the flexible belt 3, thereby preventing the end of the flexible belt 3 from escaping from the detection wheel 12 and affecting the operation of other transmission components of the toner cartridge 100.

[0045] The thickness h of the flexible belt 3 is 0.5 mm to 3 mm, and the flexible belt 3 is made of materials such as polyvinyl chloride, polyurethane, polyethylene, polypropylene or nylon, wherein the thickness h of the flexible belt 3 can be selected according to the material of the flexible belt 3 to avoid plastic deformation of the flexible belt 3 due to tension during use, thereby ensuring the rotation stability and rotation reliability of the detection wheel 12 when it is rotated. In addition, the minimum spacing w between the arc surface 121 of the detection wheel 12 and the second cylindrical surface 211 of the transmission wheel 21 is 2 to 6 times the thickness h of the flexible belt 3. By setting the minimum spacing w between the arc surface 121 of the detection wheel 12 and the second cylindrical surface 211 of the transmission wheel 21, it can be ensured that when the flexible belt 3 is disconnected from the detection wheel 12 and is completely wound onto the transmission wheel 21, the flexible belt 3 does not contact the detection wheel 12, thereby preventing the flexible belt 3 from continuing to drive the detection wheel 12 to rotate through friction, and preventing the printer's detection mechanism from misdetecting or misdetecting the toner cartridge 100.

[0046] It should be noted that the steering of the detection wheel 12 can be set to rotate in the same direction according to the detection structure and detection direction of the detection mechanism of the printer. When the steering of the detection wheel 12 needs to be the same as the steering of the transmission wheel 21, the line connecting the first tangent point between the flexible belt 3 and the transmission wheel 21 and the second tangent point between the flexible belt 3 and the detection wheel 12 is parallel to the shortest line between the rotation axis of the transmission wheel 21 and the rotation axis of the detection wheel 12. It can be seen that the relative steering of the transmission wheel 21 and the detection wheel 12 can be changed by different winding methods of the flexible belt 3 between the transmission wheel 21 and the detection wheel 12, so that the toner cartridge 100 can be set accordingly according to the detection mechanism of the printer. Furthermore, the shape and structure of the mating surface between the detection wheel 12 and the flexible belt 3 can be adjusted according to the production process, production cost and design requirements. For example, the arc surface 121 on the detection wheel 12 can be replaced with a first cylindrical surface, and the connection method between the first cylindrical surface and the flexible belt 3, the minimum distance between the first cylindrical surface and the second cylindrical surface 211 and other settings are the same as the arc surface 121, so they are not repeated here.

[0047] The powder feeding roller 3 is rotatably mounted on the box body 1 around its own axis, and the powder feeding roller 3 is located in the powder bin 11 and at the powder outlet of the powder bin 11. The first end of the powder feeding roller 3 close to the second end wall of the box body 1 extends out of the second end wall, and a powder feeding roller gear 31 is provided on the end thereof, and the powder feeding roller gear 31 is fixedly connected to the powder feeding roller 3, and the powder feeding roller gear 31 is meshed with the second gear 132 on the power receiving head 13, so that the power receiving head 13 can drive the powder feeding roller 3 to rotate through the second gear 132 and the powder feeding roller gear 31, thereby transferring the carbon powder in the powder bin 11 to the developing roller 4.

[0048] The developing roller 4 is rotatably mounted on the box body 1 around its own axis, and is located outside the powder bin 11 and at the outlet of the powder bin 11. The developing roller 4 is adjacent to the powder feeding roller 3 to receive the carbon powder delivered by the powder feeding roller 3. One end of the powder feeding roller 3 close to the second end wall of the box body 1 extends out of the second end wall, and a developing roller gear 41 is provided on the end thereof. The developing roller gear 41 is fixedly connected to the developing roller 4, and the developing roller gear 41 is meshed with the first gear 131 on the power receiving head 13, so that the power receiving head 13 can drive the developing roller 4 to rotate through the first gear 131 and the developing roller gear 41.

[0049] In summary, it can be seen that the flexible belt is wrapped between the transmission wheel and the detection wheel, so that the transmission wheel can drive the detection wheel to rotate through the flexible belt, and then the detection mechanism on the printer can detect the toner cartridge through the detection wheel; and because the detection wheel is only used once in a life cycle of the toner cartridge, the transmission wheel and the detection wheel are connected by the flexible belt, and the detection wheel is disconnected from the flexible belt after rotating a preset angle, which can ensure that the detection wheel is only driven once, so as to avoid the detection mechanism of the printer from detecting the toner cartridge multiple times in a life cycle of the toner cartridge, thereby preventing the printer from misjudging or misjudging the use status of the toner cartridge. In addition, the structural design of the toner cartridge can also effectively reduce the production cost of the toner cartridge, simplify the structure of the toner cartridge, and appropriately reduce the torque on the power receiving head, and protect the drive head of the printer.

[0050] Toner cartridge second embodiment:

[0051] The difference between this embodiment and the first embodiment of the toner cartridge is that in this embodiment, the transmission wheel on the first end of the stirring frame is eliminated, the detection wheel is set on the second end wall, and the flexible belt is wrapped between the power receiving head and the detection wheel.

[0052] Specifically, a third cylindrical surface having the same function as the second cylindrical surface on the transmission wheel of the first embodiment of the toner cartridge is provided on the power receiving head, and the first end of the flexible belt is wound around the cylindrical surface of the detection wheel or the first cylindrical surface, and the second end of the flexible belt is wound around the third cylindrical surface of the power receiving head, so that the flexible belt can be disconnected from the detection wheel after the detection wheel is driven to rotate to a preset angle under the winding of the power receiving head.

[0053] Among them, the setting principles of the parameter settings between the power receiving head and the flexible belt (such as the initial length of the flexible belt wrapped around the third cylindrical surface), and the parameter settings between the power receiving head and the detection wheel (such as the minimum spacing between the third cylindrical surface and the arc surface, or the minimum spacing between the third cylindrical surface and the first cylindrical surface; the size of the adhesive force between the flexible belt and the power receiving head) are the same as the setting principles of the parameter settings between the transmission wheel and the flexible belt, and the parameter settings between the transmission wheel and the detection wheel in the first embodiment of the toner cartridge, so they are not repeated here.

[0054] It should be noted that, since there are more transmission elements on the second end wall, in this embodiment, the minimum distance between the third cylindrical surface and the arc surface or the minimum distance between the third cylindrical surface and the first cylindrical surface can be appropriately increased.

[0055] Toner cartridge third embodiment:

[0056] The difference between this embodiment and the above embodiments is that:

[0057] In this embodiment, the arc surface or the first cylindrical surface of the detection wheel is provided with scale lines, and the first end wall or the second end wall of the box body is provided with a mark (such as an arrow, an indication point) matching the scale lines, so as to facilitate the assembly of the toner cartridge and make recycling easier, so that the positioning of the detection wheel can be completed without the need for professional tools and / or professional personnel, thereby ensuring the accuracy of the initial position of the detection wheel after the toner cartridge is assembled. Among them, when the detection wheel is provided on the first end wall of the box body, a mark matching the scale lines can be provided only on the first end wall; when the detection wheel is provided on the second end wall of the box body, a mark matching the scale lines can be provided only on the second end wall.

[0059] The printer includes the toner cartridges described in the first to third embodiments of the toner cartridges, and the printer provided with the toner cartridges can ensure the detection accuracy of the toner cartridges, and can better avoid damage to the drive head, and can also reduce the use cost of the toner cartridges.

[0060] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
