[0002] A toner cartridge is a component of a copier, with a function similar to the drum powder bin of a printer. It is in the shape of a thin cylinder and its surface is covered with toner powder.

[0003] In order to ensure that the printing quality of the printer is not affected by the previous print, using the scraper technology, the toner powder particles that were not completely adsorbed onto the paper during the previous print are scraped off by the scraper and collected in the waste powder bin for storage. In this way, the printed product will not be affected by the possible impact of the previous print, ensuring the printing quality.

[0004] After scraping off the toner powder particles on the transfer roller and collecting them in the drum powder bin, the drum powder bin needs to be cleaned regularly so that it can collect waste powder again. In the prior art, when cleaning the waste powder of the toner cartridge, the waste powder opening is opened, the waste powder in the toner powder bin of the toner cartridge is poured out, and then it is covered. When pouring out the waste powder, there is a situation where the waste powder spills, and it is easily poured into the toner cartridge. After manually cleaning the waste powder, the toner cartridge needs to be cleaned again, increasing the workload of the user. Therefore, we propose a powder cleaning mechanism for a copier toner cartridge. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] An embodiment of the present utility model discloses a toner cleaning mechanism for a copier toner cartridge.

[0023] According to the attached Figures 1-4 As shown, it includes a toner cartridge 1. An internal transfer roller 2 is drivingly connected inside the toner cartridge 1. A drum powder bin 3 is installed inside the toner cartridge 1. A scraper 301 is fixedly connected to the outer wall of the drum powder bin 3. The scraper 301 is in contact with the outer peripheral wall of the transfer roller 2. During the rotation of the transfer roller 2, copying is carried out. By contacting the transfer roller 2 with the scraper 301, the waste powder on the transfer roller 2 is scraped off and collected in the drum powder bin 3 to avoid the waste powder affecting the printing effect. A mounting seat 4 is fixedly connected to the inner wall of the toner cartridge 1. The following are provided on the toner cartridge 1:

[0024] A communication unit 5. The communication unit 5 includes a communication pipe 501 slidably connected to the inner wall of the toner cartridge 1. A communication port 504 is opened on the drum powder bin 3. The communication pipe 501 is arranged corresponding to the communication port 504. By pulling the drum powder bin 3 to move, the communication pipe 501 coincides with the communication port 504. Under the rebound of the communication port 504, the communication pipe 501 is pushed to be inserted into the communication port 504. At this time, the communication pipe 501 is communicated with the inner wall of the drum powder bin 3, which is convenient for removing the waste powder and avoiding the waste powder falling into the toner cartridge 1 during the removal of the waste powder, and requires manual cleaning of the toner cartridge 1 later.

[0025] An extrusion unit 6. The extrusion unit 6 includes a sliding seat 601 fixedly connected to the drum powder bin 3. The sliding seat 601 is slidably connected to the inner wall of the mounting seat 4. A limiting spring 605 is fixedly connected to the top end face of the sliding seat 601. By extruding the sliding seat 601 through the limiting spring 605, the scraper 301 on the drum powder bin 3 driven by the sliding seat 601 is extruded against the transfer roller 2 to ensure the powder scraping effect. At the same time, under the extrusion of the limiting spring 605, the drum powder bin 3 is installed in the mounting seat 4 to ensure the stable position of the drum powder bin 3.

[0026] A compression spring 503 is sleeved on the outer peripheral wall of the communication unit 5.

[0027] One end of the compression spring 503 is fixedly connected to the toner cartridge 1, and the other end of the compression spring 503 is fixedly connected with an extrusion seat 502. The extrusion seat 502 is fixedly connected to the outer peripheral wall of the communication pipe 501. Under the rebound of the compression spring 503, the communication pipe 501 is pushed to fit against the inner wall of the drum powder bin 3. When the drum powder bin 3 is pulled to move, the communication pipe 501 coincides with the communication port 504. Under the rebound of the communication port 504, the communication pipe 501 is pushed to be inserted into the communication port 504. At this time, the communication pipe 501 is communicated with the inner wall of the drum powder bin 3, which is convenient for removing waste powder and avoiding waste powder falling into the toner cartridge 1 when removing waste powder.

[0028] After the waste powder removal is completed, by pushing the drum powder bin 3 to move towards each other, at this time the communication pipe 501 is separated from the communication port 504, so that the communication pipe 501 fits against the drum powder bin 3, and at this time the drum powder bin 3 resumes collecting waste powder.

[0029] A threaded rod 602 is fixedly connected to the inner wall of the mounting seat 4.

[0030] A contact seat 603 is slidably connected to the outer peripheral wall of the threaded rod 602.

[0031] The contact seat 603 is fixedly connected to the limit spring 605. By squeezing the limit spring 605 through the contact seat 603, the limit spring 605 is compressed. Under the rebound of the limit spring 605, the sliding seat 601 is squeezed, so that the position of the drum powder bin 3 in the mounting seat 4 is relatively stable. At the same time, through the squeezing of the sliding seat 601 by the limit spring 605, the scraper 301 on the drum powder bin 3 is squeezed against the transfer roller 2 to ensure the powder scraping effect.

[0032] A nut seat 604 is threadedly connected to the outer peripheral wall of the threaded rod 602. The nut seat 604 is rotatably connected to the contact seat 603. By rotating the nut seat 604, the position of the contact seat 603 on the threaded rod 602 is adjusted, the compression degree of the limit spring 605 is adjusted, the squeezing of the sliding seat 601 is changed, and thus the squeezing force between the scraper 301 and the transfer roller 2 is controlled. By rotating the nut seat 604 to separate from the sliding seat 601, the sliding seat 601 can be removed from the mounting seat 4 to complete the disassembly of the drum powder bin 3.

[0033] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
