[0023] Example 1

[0024] like Figures 1-4 As shown in the figure, the toner cartridge for recycling residual toner proposed in this embodiment includes a shell 1, an ink storage box 2, a sealing mechanism, and a residual toner conveying mechanism.

[0025] The photosensitive roller 3, the developing roller 4, and the sponge roller 5 are rotatably mounted on the inner side of the outer casing 1; a side casing 8 is provided on the side of the sponge roller 5.

[0026] The ink storage box 2 is located inside the outer shell 1. The upper and lower ends of the ink storage box 2 are respectively provided with a feeding pipe 9 and a powder inlet box 18. The feeding pipe 9 is located above the sponge roller 5 and the side shell 8. A desiccant box is provided inside the outer shell 1. The desiccant box contains desiccant. A vent pipe connects the desiccant box and the ink storage box 2.

[0027] The sealing mechanism includes a side plate 23, a sealing plate 24, and an elastic connecting assembly. The sealing plate 24 movably passes through the inner and outer sides of the feed pipe 9. The side plate 23 is connected to the sealing plate 24. The sealing plate 24 is connected to the feed pipe 9 through the elastic connecting assembly. The elastic connecting assembly includes a guide rod 20, a second spring 21, and a limiting block 22. The guide rod 20 is connected to the outer wall of the feed pipe 9 and passes through the side plate 23. The limiting block 22 is located at the end of the guide rod 20. The second spring 21 is sleeved and installed on the guide rod 20.

[0028] The residual powder conveying mechanism is arranged inside the shell 1, and comprises a dust suction head 6, two scrapers 7, a micro dust collector, an air charging pipe 10, a first connecting pipe 111, a second connecting pipe 112, a spray head 12, a sealing piston 15, a movable rod 16 and a first spring 17. The dust suction head 6 is arranged below the developing roller 4 and the sponge roller 5. The scrapers 7 are arranged in contact with the surfaces of the developing roller 4 and the sponge roller 5 respectively. The scrapers 7 are connected with the inner wall of the shell 1. The input end of the micro dust collector is connected with the dust suction head 6, and the output end thereof is connected with the bottom end of the air charging pipe 10 through the first connecting pipe 111. The sealing piston 15 is movably arranged inside the air charging pipe 10. The first spring 17 is arranged on the upper portion of the air charging pipe 10. The movable rod 16 movably penetrates the upper end of the air charging pipe 10 and is connected with the sealing piston 15. The upper end of the movable rod 16 is wedge-shaped. The spray head 12 is arranged on the upper end of the powder inlet box 18. The spray head 12 is connected with the air charging pipe 10 through the second connecting pipe 112. The connecting plate 14 is connected with the side plate 23, and a rectangular hole is arranged in the connecting plate 14.

[0029] Specifically, when the printing work is started, the micro dust collector starts to work. The two scrapers 7 scrape the residual powder on the surfaces of the developing roller 4 and the sponge roller 5 respectively. The scraped residual powder is sucked by the dust suction head 6 and enters the inside of the air charging pipe 10. At this time, the pressure at the lower end of the inner cavity of the air charging pipe 10 gradually increases, which pushes the sealing piston 15 to move downward. When the sealing piston 15 moves to the upper end of the second connecting pipe 112, the sealing piston 15 stops moving upward. When the sealing piston 15 moves, the movable rod 16 also moves. The inclined surface at the upper end of the movable rod 16 is inserted into the rectangular hole of the connecting plate 14, so as to push the connecting plate 14 to move. The movement of the connecting plate 14 drives the sealing plate 24 to move. At this time, the powder outlet pipe 9 is in a connected state. The carbon powder in the ink storage box 2 flows out to the surface of the sponge roller 5 through the powder outlet pipe 9, so that the carbon powder is attached to the surface of the sponge roller 5. The absorbed residual powder enters the spray head 12 through the second connecting pipe 112, and finally is discharged into the inside of the powder inlet box 18 through the spray head 12, so as to realize the collection of the residual powder. When the equipment stops running, the micro dust collector stops working. The pressure at the bottom end of the inside of the air charging pipe 10 decreases. Under the elastic force of the first spring 17, the sealing piston 15 and the movable rod 16 are automatically reset. Under the elastic force of the elastic connecting assembly, the sealing plate 24 is also automatically reset, so as to realize the automatic sealing of the bottom opening of the powder outlet pipe 9, and to keep the ink storage box 2 in a sealed state, so as to prevent the carbon powder inside from being damp.
