[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a toner cartridge that can assist in adding toner, including a toner cartridge body 1 for providing toner, a feed pipe 2 for feeding is connected through the upper part of the inner wall of the toner cartridge body 1, a screw cap 3 for sealing is threadedly connected to the upper part of the feed pipe 2, and a feeding mechanism 4 for assisting in feeding and a dehumidification mechanism 5 for dehumidifying the toner are provided inside the toner cartridge body 1.

[0026] The feeding mechanism 4 includes a toner cartridge body 1 with a square shell 401 connected to the front for mounting components. An arc-shaped toothed plate 402 for providing power is rotatably connected to the inner wall of the square shell 401 via a rotating shaft. The arc-shaped toothed plate 402 passes through and is slidably connected to the inner wall of the square shell 401. A small gear 403 for driving a large gear 404 to rotate is meshed on one side of the arc-shaped toothed plate 402. A large gear 404 for driving a spur gear 405 to rotate is rotatably connected to the back of the small gear 403. Both the small gear 403 and the large gear 404 pass through and are rotatably connected to the inner wall of the square shell 401.

[0027] The toner cartridge that assists in adding toner has a torsion spring fitted onto the rotating shaft of the arc-shaped toothed plate 402. One end of the torsion spring is mounted on the arc-shaped toothed plate 402, and the other end is mounted on the inner wall of the square shell 401. When the arc-shaped toothed plate 402 is released, the torsion spring resets the arc-shaped toothed plate 402. When the arc-shaped toothed plate 402 is pressed, the arc-shaped toothed plate 402 drives the pinion 403 and the gear 404 to rotate together.

[0028] exist Figure 1 and Figure 4In the middle, a spur gear 405 is meshed with one side of the large gear 404 to drive the connecting plate 406 to rotate. The spur gear 405 passes through and is rotatably connected to the inner wall of the square shell 401. The connecting plate 406 is fixedly connected to the back of the spur gear 405 to drive the pawl 407 to rotate. The pawl 407 is rotatably connected to the back of the connecting plate 406 via a rotating shaft to drive the ratchet 409 to rotate. A spring 408 is connected to the outside of the pawl 407 to drive the pawl 407 to reset. The spring 408 is connected to the outside of the connecting plate 406.

[0029] The outer side of the pawl 407 is engaged with a ratchet 409 for driving the bevel gear a411 to rotate.

[0030] The toner cartridge that assists in adding toner has a spring 408 that drives a pawl 407 to rotate and engage with a ratchet 409. When the large gear 404 rotates, it drives the spur gear 405 and the connecting plate 406 to rotate, thereby driving the ratchet 409 to rotate. When the arc-shaped toothed plate 402 is released and reset, the connecting plate 406 rotates in the opposite direction, and the pawl 407 slips inside the ratchet 409. The damping bearing provides resistance to prevent the ratchet 409 from rotating in the opposite direction.

[0031] exist Figure 3 In the middle, the inner wall of the toner cartridge body 1 is connected to a housing 410 for protecting the bevel gears a411 and b412. The upper part of the inner wall of the housing 410 is connected through a damping bearing to an auger 413 for feeding material. The auger 413 is set in the feed pipe 2.

[0032] The toner cartridge that assists in adding toner will have an auger 413 extending into the bottle opening when the toner bottle is inserted into the feed tube 2. As the auger 413 rotates, it can clear the toner in the toner bottle and the feed tube 2, preventing blockages when adding toner.

[0033] exist Figure 3 In the middle, the outer side of the auger 413 is connected to a bevel gear b412 for driving the auger 413 to rotate. The front part of the bevel gear b412 is meshed with a bevel gear a411 for driving the bevel gear b412 to rotate. The bevel gear a411 is rotatably connected to the inner wall of the housing 410 through a bracket, and the bevel gear a411 passes through the inner wall of the toner cartridge body 1 through a damping bearing and is connected to the back of the ratchet 409.

[0034] The toner cartridge that assists in adding toner has a ratchet 409 that drives a bevel gear a411 to rotate when it rotates. The bevel gear a411 then drives the bevel gear b412 and the auger 413 to rotate.

[0035] exist Figure 5 and Figure 6In the dehumidification mechanism 5, there is a hollow box 501 that is connected through the upper part of the inner wall of the toner cartridge body 1 near the feed pipe 2. The hollow box 501 is used to store desiccant 504. A sealing cover 502 for sealing is connected above the hollow box 501. A rubber gasket for sealing is abutted between the hollow box 501 and the sealing cover 502.

[0036] The toner cartridge that assists in adding toner has a rubber gasket glued to the top of the perforated cartridge 501. After the cover 502 is installed on the perforated cartridge 501, the rubber gasket is squeezed to seal it. The cover 502 and the perforated cartridge 501 are connected by screws or plastic clips.

[0037] exist Figure 5 and Figure 6 In the hollow box 501, a filter screen 503 for ventilation is connected to the inner wall, and a desiccant 504 for absorbing moisture is placed inside the hollow box 501.

[0038] The toner cartridge that assists in adding toner has a filter 503 that prevents toner from entering the perforated box 501, while allowing air to enter the perforated box 501. The desiccant 504 absorbs moisture from the air inside the toner cartridge body 1, drying the toner inside the toner cartridge body 1 and preventing the toner from becoming damp and clumping. The desiccant 504 should be replaced periodically according to the usage time.

[0039] In summary: When using this type of toner cartridge with assisted toner refilling, firstly, remove the toner cartridge body 1 from the printer, rotate and open the screw cap 3, open the toner bottle cap for refilling, and insert the bottle opening into the feed tube 2. If the toner has difficulty entering the toner cartridge body 1, press the arc-shaped toothed plate 402 to drive the auger 413 to rotate, assisting the toner to enter the toner cartridge body 1. After adding toner, rotate and close the screw cap 3. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
