[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 3-Figure 5 The utility model provides an embodiment: a printer toner cartridge capable of recycling waste toner, comprising a shell 1, a waste toner box 2 is fixedly connected to the bottom of the shell 1, a motor 3 is fixedly connected to the left side of the waste toner box 2, a cage 4 is fixedly connected to the output end of the motor 3, the cage 4 is rotatably connected to the inside of the waste toner box 2, a powder discharge port 9 is provided at the bottom of the right side of the waste toner box 2, the powder discharge port 9 is arranged below the cage 4, a toner box 5 is fixedly connected to the rear side of the inner wall of the waste toner box 2, a developing roller 6, a charging roller 7 and a photosensitive drum 8 are rotatably connected to the inner wall of the shell 1, the charging roller 7 is arranged at the front end of the toner box 5, the charging roller 7 is arranged at the bottom of the photosensitive drum 8, the photosensitive drum 8 is arranged at the front end of the developing roller 6, a cleaning component is arranged inside the shell 1, a reserved opening 24 is provided at the front end of the shell 1, the reserved opening 24 corresponds to the photosensitive drum 8, a cleaning scraper 10 is fixedly connected to the inner wall of the shell 1, and one end of the cleaning scraper 10 keeps a distance from the developing roller 6.

[0035] The printer is started to rotate the developing roller 6, the charging roller 7 and the photosensitive drum 8. The rotation of the developing roller 6 absorbs the toner in the toner box 5. The rotation of the charging roller 7 makes the surface of the photosensitive drum 8 evenly charged and absorbs the toner on the surface of the developing roller 6. When the photosensitive drum 8 rotates, the toner can be driven to the transfer roller above the shell 1 through the reserved opening 24. The charging roller 7 does not absorb the toner itself when it rotates. When the developing roller 6 rotates, the excess toner is scraped off by the cleaning scraper 10, so as to control the amount of toner on the surface of the developing roller 6. The scraped toner falls into the waste toner box 2. The two sides of the waste toner box 2 are beveled, which can ensure that the toner is always gathered at the cage 4 in the center of the waste toner box 2. When the toner in the waste toner box 2 accumulates to a certain amount, the motor 3 is started. The motor 3 drives the cage 4 to rotate in the waste toner box 2, moves the toner in the waste toner box 2 to the right and discharges it through the powder discharge port 9 for recycling.

[0036] Reference Figure 3 and Figure 4 The cleaning component includes a cleaning scraper 11 and a powder discharge knife 12. The powder discharge knife 12 and the powder discharge knife 12 are both fixedly connected to the inner wall of the shell 1. The cleaning scraper 11 abuts against the outer wall of the photosensitive drum 8, and the powder discharge knife 12 abuts against the outer wall of the developing roller 6.

[0037] When the photosensitive drum 8 rotates, the cleaning scraper 11 scrapes the remaining toner on the outer wall and drops it into the waste toner box 2. When the developing roller 6 rotates, the powder discharge knife 12 scrapes the remaining toner on the outer wall and drops it into the waste toner box 2.

[0038] Reference Figure 1 , Figure 2 and Figure 7 A hinge 15 is fixedly connected to the rear side of the shell 1, and a cover plate 16 is rotatably connected to the top of the hinge 15. The front end of the cover plate 16 is fixedly connected to left and right opposite clamping blocks 17. The front end of the shell 1 is fixedly connected to left and right opposite fixing frames 18. The two fixing frames 18 are slidably connected with clamping rods 19 inside. The opposite sides of the two clamping rods 19 are clamped in the two clamping blocks 17. The middle parts of the two clamping rods 19 are fixedly connected to limit rings 20. The opposite sides of the two limit rings 20 are fixedly connected to springs 1 21. The two springs 1 21 are respectively arranged in the two fixing frames 18. The bottom of the adjacent sides of the two clamping blocks 17 are provided with beveled sides 1 22. The opposite sides of the two clamping rods 19 are provided with beveled sides 23. The two beveled sides 23 correspond to the two beveled sides 1 22 respectively.

[0039] The cover 16 is rotated downward through the hinge 15 to cover the top of the shell 1, and the two locking blocks 17 are driven to descend together. When the two locking blocks 17 descend, the two beveled edges 1 22 are used to press against the two beveled edges 2 23, and the two locking rods 19 are pushed open to slide in the two fixed frames 18, and the springs 1 21 on both sides are squeezed through the two limiting rings 20 respectively, until the cover 16 drives the locking blocks 17 to fall completely. At this time, the two springs 1 21 will rebound to the two limiting rings 20, so that the two locking rods 19 move away from each other and respectively snap into the two locking blocks 17, completing the fixing of the shell 1 and the cover 16 to be closed. When it needs to be opened, the two locking rods 19 are pulled to slide in the two locking blocks 17 and approach each other, so that the two locking rods 19 leave the two locking blocks 17. At this time, the cover 16 can be rotated upward to open it and display the internal situation of the shell 1.

[0040] Reference Figure 4-Figure 6 A thread groove 14 is provided on the right side of the waste powder box 2 , and the powder discharge port 9 is arranged inside the thread groove 14 . A rotating cap 13 is threadedly connected to the inner wall of the thread groove 14 , and the rotating cap 13 abuts against the right side of the powder discharge port 9 .

[0041] The cap 13 is threadedly rotated into the thread groove 14 to block the powder discharge port 9 to prevent leakage of toner. When toner needs to be discharged, the cap 13 is threadedly rotated to leave the thread groove 14 and the toner in the waste toner box 2 is discharged through the powder discharge port 9.

[0042] Reference Figure 1 and Figure 2A slide plate 25 is slidably connected to the left rear side of the top of the cover plate 16, and a uniformly distributed spring 26 is fixedly connected to the right side of the slide plate 25. Multiple springs 26 are fixedly connected to the inside of the cover plate 16, and the slide plate 25 corresponds to the toner box 5.

[0043] Slide the slide plate 25 to the left and squeeze the spring 26 to display the toner box 5. At this time, you do not need to refill the toner. After refilling, release the slide plate 25. The slide plate 25 is slid to the right by the rebound of the spring 26 to block the toner box 5. When the cover 16 is closed, the rear side of the bottom of the inner wall will abut against the top of the toner box 5 to avoid leakage.

[0044] Working principle: When in use, start the printer to rotate the developing roller 6, charging roller 7 and photosensitive drum 8 respectively. When the developing roller 6 rotates, it absorbs the toner in the toner box 5. The photosensitive drum 8 is evenly charged by the rotation of the charging roller 7 and absorbs the toner on the surface of the developing roller 6. Then, the toner on the outer wall of the photosensitive drum 8 is driven to the transfer roller above the shell 1 through the reserved opening 24. When the developing roller 6 rotates, the excess toner is scraped off by the cleaning scraper 10 and falls into the waste toner box 2. The remaining toner on the outer walls of the developing roller 6 and the photosensitive drum 8 are scraped off by the cleaning scraper 2 11 and the powder discharge knife 12 and fall into the waste toner box 2. The two sides of the waste toner box 2 are beveled, so that the toner gathers to the cage 4 in the center of the waste toner box 2. When the toner in the waste toner box 2 accumulates to a certain amount, the motor 3 is started to rotate the cage 4. Move the toner in the waste toner box 2 to the right and discharge it through the powder discharge port 9 for recycling, rotate the cover 16 downward through the hinge 15, and the two locking blocks 17 will also drop together, and the two beveled edges 1 22 will press against the two beveled edges 2 23, push the two locking rods 19 open and close to each other, and at the same time squeeze the springs 1 21 on both sides through the two limiting rings 20. When the cover 16 drives the locking blocks 17 to completely drop, the two springs 1 21 will rebound, and the two locking rods 19 will be pushed away from each other and locked into the two locking blocks 17 through the two limiting rings 20, so as to fix the closure of the shell 1 and the cover 16. When it needs to be opened, pull the two locking rods 19 closer to each other and leave the two locked locking blocks 17, and then rotate the cover 16 upward to open it, so as to facilitate cleaning and maintenance inside the shell 1.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
