[0001] This utility model relates to the field of toner cartridge technology, and in particular to a highly efficient and toner-saving toner cartridge toner discharge mechanism. Background Technology
[0002] A toner cartridge is a key component used in laser printers or copiers, also known as a photosensitive drum or photoconductive drum. It mainly consists of a cylindrical aluminum substrate and a layer of photoconductive material on the surface. During printing, the toner cartridge is first charged to a certain potential. Then, a laser beam exposes the surface of the toner cartridge according to the information to be printed. The exposed areas lose their charge due to the light, forming an electrostatic latent image corresponding to the printed content. Next, toner with the opposite charge is attracted to these areas from the toner ejection mechanism of the toner cartridge, forming a visible image. Finally, these images are transferred to paper and fixed by heat, completing the printing process.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0027] Please see Figures 1 to 4This embodiment provides a high-efficiency toner-saving drum unit toner discharge mechanism, including: a drum unit 1, which is used for adding and discharging toner. The drum unit 1 includes a toner guide strip 15 and a toner discharge port 14. The toner guide strip 15 is fixedly disposed on the inner bottom surface of the drum unit 1. The toner guide strip 15 is inclined at 10°~20°, preferably 15° in this embodiment, which is conducive to the toner sliding to the toner discharge port 14. The toner discharge port 14 is fixedly disposed on the bottom side of the drum unit 1. The toner discharge port 14 is inclined at 15°~30°, preferably 25° in this embodiment, which can discharge all the toner in the toner guide strip 15. The toner guide strip 15 is connected to the toner discharge port 14, and the bottom end of the toner guide strip 15 and the bottom end of the toner discharge port 14 are at the same height.
[0028] Toner storage section 2 is fixedly installed inside the upper part of the drum unit 1 and is used to store toner. The bottom of the toner storage section 2 has a slope that is opposite to the tilt direction of the toner guide strip 15 and has the same tilt angle.
[0029] There are several dispersing parts 3, all of which are fixedly installed at the bottom of the toner storage part 2 and extend into the toner guide bar 15. When the toner in the toner storage part 2 is about to run out, the toner slides along the slope at the bottom of the toner storage part 2 and gathers together, falling into the toner guide bar 15 and being collected by the toner guide bar 15. When passing through the dispersing parts 3, the toner is dispersed by the multiple dispersing parts 3 in sequence and slides towards the toner discharge port 14, from which it is sprayed out.
[0030] The drum unit 1 also includes a cover part and a drum body part. The drum body part includes a drum body 11 and a lower drum cavity 17. The cover part includes a toner inlet 12, a toner inlet cover 13 and a toner outlet cover 16.
[0031] The lower cavity 17 of the toner cartridge is located inside the lower part of the toner cartridge body 11 and below the toner storage section 2. The toner filling port 12 is located on the upper side of the toner cartridge body 11. The toner filling port cover 13 is located on the top of the toner filling port 12 and is threadedly connected to the toner filling port 12. The toner discharge port cover 16 is located at the inner end of the toner discharge port 14 and is hinged to the side of the toner cartridge body 11. A spring sheet is provided between the toner discharge port cover 16 and the side of the toner cartridge body 11. When there is no external force, the toner discharge port cover 16 covers the toner discharge port 14. When the printer starts working, it draws the toner to open the toner discharge port cover 16 and sprays it out of the toner discharge port 14.
[0032] The toner storage section 2 includes a toner storage box 21, several dividing strips 23 and an inlet / outlet section. The inlet / outlet section includes a toner outlet 22 and a toner inlet 24. The toner storage box 21 is fixedly installed inside the drum body 11 at the top. The toner inlet 24 is located on the side of the toner storage box 21 at the top and is directly opposite the toner filling port 12, which facilitates the addition of toner into the toner storage box 21.
[0033] The toner outlet 22 is located at the bottom front of the toner storage box 21. The bottom of the toner storage box 21 is provided with a ramp that slopes towards the toner outlet 22. Dividing strips 23 are fixedly installed at the bottom of the toner storage box 21 to divide the bottom of the toner storage box 21 into several parts, so as to prevent the remaining toner from accumulating and clumping together, which would affect its use.
[0034] The dispersing part 3 includes a connecting part and a bristle part. The connecting part includes a connecting rod 31 and a connecting plate 32. The upper end of the connecting rod 31 is fixedly connected to the bottom of the powder storage box 21, and the lower end is fixedly connected to the middle of the upper surface of the connecting plate 32.
[0035] The brush part includes several brush rods 33 and several brush bristles 34. The brush rods 33 are all fixedly installed at the bottom of the connecting plate 32, and the brush bristles 34 are all fixedly installed at the bottom of the brush rods 33. The brush bristles 34 extend into the toner guide strip 15. When the toner slides through the brush bristles 34 in the toner guide strip 15, it is blocked and dispersed by the brush bristles 34 to prevent it from clumping.
[0036] Unscrew the toner filling cap 13 and add toner into the toner filling port 12. The toner enters the toner storage box 21 through the toner inlet 24. Because the bottom of the toner storage box 21 is sloped towards the toner outlet 22, the toner slides along the bottom of the toner storage box 21 towards the toner outlet 22, and leaks from the toner outlet 22 into the lower chamber of the drum 17. It then slides along the inclined toner guide strip 15 towards the toner discharge port 14, where it is stopped by the toner discharge port cap 16. After the lower chamber of the drum 17 and the toner storage box 21 are completely filled with toner, screw on the toner filling cap 13, install the drum into the printer, and start the printer. The printer draws the toner out from the toner discharge port 14 and sprays it onto a specific area to form a visible image, completing the printing process. When there is very little toner left in the drum... The toner in the toner storage box 21 is divided into several parts by the dividing strip 23 to prevent the toner from sticking together and affecting its use. The divided toner slides to the toner outlet 22 and leaks into the lower cavity 17 of the drum. It is collected by the toner guide strip 15 and slides along the toner guide strip 15 to the toner discharge port 14. The bristles 34 disperse the flowing toner to prevent it from clumping and blocking the toner guide strip 15, which would prevent the toner from being completely discharged and wasted. The dispersed toner flows along the inclined toner guide strip 15 to the toner discharge port 14. Since the bottom end of the toner discharge port 14 and the bottom end of the toner guide strip 15 are at the same height and the toner discharge port 14 is inclined downward, the toner in the toner guide strip 15 can be completely discharged through the toner discharge port 14 without any toner remaining, thus avoiding waste.
[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
