DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] In this embodiment, if Figures 1-8As shown, the toner cartridge that is easy to reset includes a cartridge body 101. Both sides of the cartridge body 101 are connected to end covers 102 through detachable parts, which is convenient for repair and replacement of the internal structure. A gear plate 103 is rotatably installed inside one of the end covers 102, and a driving motor and a driving gear are provided inside the other end cover 102, which are convenient for driving the gear plate 103 to rotate under the cooperation between several parts. One side of the gear plate 103 is meshed with a reset gear 104. The gear plate 103 includes a rotating gear connected to the drum core, and the rotating gear and the outer tooth segment of the reset gear 104 are connected. The reset gear 104 is meshed with each other and is rotatably connected to the cartridge body 101. A powder adding port 105 is provided on one side of the cartridge body 101. The cartridge body 101 also includes a sealing mechanism 200 and a reset mechanism 300. The sealing mechanism 200 is provided inside the powder adding port 105 and is used to seal the powder adding port 105. The reset mechanism 300 is provided on one side of the reset gear 104 and is used to drive the reset gear 104 to rotate. Before using the toner cartridge that is easy to reset, first check whether the toner cartridge can be used normally, and then adjust the reset mechanism 300 to put the toner cartridge into a ready-to-use state.

[0034] The sealing mechanism 200 includes a sealing cover 201 threadedly connected to the powder adding port 105. A sealing strip 202 is provided on the side of the sealing cover 201 close to the box body 101. The specifications and dimensions of the sealing strip 202 are adapted to the powder adding port 105. A rotating strip 203 is provided on the side of the sealing cover 201 away from the box body 101 to facilitate the powder adding operation and to seal the toner. The sealing strip 202 can be in close contact with the inner wall of the powder adding port 105, so that the powder adding port 105 and the sealing cover 201 are sealed, so that the toner cartridge is firmly installed, thereby improving the overall stability of the toner cartridge when adding toner.

[0035] Among them Figure 3-Figure 8 As shown, the reset mechanism 300 includes a sliding column 301 connected to the gear shaft of the reset gear 104, a sliding sleeve 302 is provided on the outer side of the sliding column 301, and the sliding sleeve 302 is slidably connected to the end cover 102. One end of the sliding sleeve 302 extends to the outside of the end cover 102 and is fixedly connected to a pressure plate 303. A spring is provided between the pressure plate 303 and the sliding column 301. The spring enables the pressure plate 303 to automatically return to its original position. A limiting component for fixing the position of the pressure plate 303 is provided on one side of the pressure plate 303. The pressure plate 303 is close to the end cover 102. A pressing assembly is provided on one side. After the staff takes the toner cartridge out of the printing device, they manually press the pressure plate 303 with the cooperation of the limit assembly, so that the guide column 306 can slide on the surface of the reset arc block 307 when pressed down, thereby driving the reset arc block 307 and the reset gear 104 to rotate, so that the reset gear 104 can smoothly engage with the gear plate 103. The entire reset process is completed by the reset gear 104 itself, and there is no need to remove the end cover 102 for the reset operation, which effectively reduces the difficulty of using the toner cartridge and the production cost;

[0036] Among them Figure 4 and Figure 8 As shown, the limiting assembly includes a support frame 304 fixedly mounted on the upper surface of the end cover 102, a circular hole is opened on the surface of the support frame 304, and a movable rod 305 is slidably set inside the circular hole, one end of the movable rod 305 is fixedly provided with a moving block, and the moving block is fixedly connected to the end cover 102 by a bolt, and the other end of the movable rod 305 is inserted into the inside of the pressure plate 303. The staff pushes the moving block to slide to one side, and then can synchronously push the movable rod 305 to be inserted into the inside of the pressure plate 303, thereby fixing the pressure plate 303, so that when the toner cartridge is in use, the pressure plate 303 can be prevented from moving due to external force, which may cause the toner cartridge to malfunction;

[0037] Among them Figure 7 and Figure 8 As shown, the pressing assembly includes a guide post 306 fixedly connected to the pressure plate 303, the pressure plate 303 and the end cover 102 are connected by a compression spring, the compression spring is sleeved on the outside of the guide post 306, the guide post 306 is slidably connected to the end cover 102, and a reset arc block 307 is provided on the side of the reset gear 104 close to the pressure plate 303. The reset arc block 307 is designed to surround the gear shaft of the reset gear 104 from bottom to top. Through the mutual cooperation between the arc block 307 and the guide post 306, the rotation reset of the reset gear 104 is achieved, which is convenient for restarting the counting operation of the toner cartridge;

[0038] Among them Figure 5-Figure 8 As shown, a toothless notch 106 is provided on the outer side of the reset gear 104. When the toothless notch 106 of the reset gear 104 rotates to the side of the rotating gear, the reset gear 104 cannot mesh with the rotating gear, thereby making the toner cartridge unable to be used normally.

[0039] Among them Figure 8 As shown, a limit ring is provided on the outer side of the movable rod 305. The size of the limit ring is adapted to the outer contour of the pressure plate 303. The outer diameter of the limit ring is larger than the inner diameter of the circular hole, which restricts the movable rod 305 and prevents the movable rod 305 from falling, which would cause the structure to be unable to be used normally.

[0040] Among them Figure 7 and Figure 8 As shown, the bottom end of the guide column 306 is designed with an arc surface. The specifications and dimensions of the arc surface of the guide column 306 are adapted to the reset arc block 307, so that the guide column 306 can smoothly contact the reset arc block 307, thereby realizing the pressing operation of the reset arc block 307, which is convenient for driving the reset gear 104 to rotate, so that the reset gear 104 can smoothly engage with the rotating gear;

[0041] Example 2

[0042] The difference from Example 1 is that Figures 9-11 As shown, the sealing mechanism 200 also includes a fixing ring 204 arranged inside the powder adding port 105, and two bayonet holes are provided on the surface of the fixing ring 204. The interior of the fixing ring 204 is rotatably connected to a powder filling cover 205, and one side of the powder filling cover 205 is movably connected to a card plate 206 through a telescopic member. The telescopic member can be set as a telescopic rod and a pressing spring component, so that the card plate 206 can be pressed, so that the card plate 206 can smoothly contact the bayonet hole, and then the powder filling cover 205 is rotated so that the card plate 206 can be rotated into the card slot. With the cooperation of the pressing spring, the card plate 206 contacts the card slot to play a limiting role, thereby fixing the position of the powder filling cover 205, the card plate 206 is adapted to the shape and specifications of the bayonet hole, and a card slot is provided inside the fixing ring 204. The card plate 206 is adapted to the shape and specifications of the card slot, which has a good sealing effect, facilitates the rapid operation of adding carbon powder, and thus avoids the leakage of carbon powder.

[0043] During use, when the carbon powder is used up and the carbon powder filling operation is performed through the sealing mechanism 200, it is necessary to reset the reset gear 104 through the reset mechanism 300. The staff only needs to manually press the pressure plate 303 so that the guide column 306 can slide on the surface of the reset arc block 307 when it is pressed down. Due to the limiting effect of the sliding sleeve 302 and the sliding column 301, when the pressure plate 303 is pressed down, it can synchronously drive the guide column 306 to move downward and contact the reset arc block 307. The arc surface design of the reset arc block 307 and the arc surface design of the bottom of the guide column 306 can make the reset arc block 307 rotate relative to each other, thereby driving the reset gear 104 to rotate, so that the reset gear 104 can smoothly engage with the gear plate 103 to achieve the reset operation.

[0044] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
