[0001] This utility model relates to the field of printer toner cartridge technology, specifically a printer toner cartridge with an anti-clogging toner outlet. Background Technology

[0002] A printer is a device that converts electronic documents into paper documents, widely used in home, office, and commercial environments. The toner cartridge is the core consumable of a laser printer, responsible for storing and delivering toner to form the printed image. The toner cartridge contains toner, and it works in conjunction with components such as the drum unit to accurately transfer the toner onto the paper.

[0003] However, existing printer toner cartridges dispense toner through the toner outlet. As a large amount of toner accumulates at the outlet over a long period of time, it can easily become clogged. The outlet lacks a structure to disperse the toner, and this blockage can affect the printer's print quality. Therefore, current printer toner cartridges need to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a printer toner cartridge with an anti-clogging toner outlet, in order to solve the problem mentioned in the background art that in the current printer toner cartridges on the market, a large amount of toner accumulates at the toner outlet for a long time, which easily causes blockage of the toner outlet, and the toner outlet does not have a structure to disperse the toner.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Equipped with a material feeding mechanism, the stirring shaft is connected to the power unit of the external printer. The stirring shaft drives the first gear to rotate in both directions, which in turn drives the second gear to rotate. Subsequently, the second gear drives the lead screw to rotate in both directions. The lead screw meshes with the moving block, causing the moving block to move left and right on the outside of the lead screw. At the same time, the moving block slides on the outside of the guide rod. The moving block then drives the material feeding plate to move left and right inside the toner outlet. This can disperse the toner accumulated at the toner outlet while discharging the toner, preventing the toner from clogging the outlet due to long-term accumulation, thus improving the toner cartridge discharging efficiency and print quality.

[0014] 2. Equipped with a transmission mechanism, a first stirring paddle, and a second stirring paddle, the mixing shaft drives the first and second stirring paddles to rotate simultaneously while the feeding mechanism pushes the toner powder apart. The second stirring paddle is located outside the first stirring paddle and has a spiral structure, which can push the toner powder to rotate. The first stirring paddle stirs and disperses the toner powder in the middle position to prevent clumping. Furthermore, the cooperation between the first and second stirring paddles can reduce the dead corners caused by toner powder accumulation, improve the uniformity of toner powder mixing, and enhance the practicality of the toner box.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a printer toner cartridge with anti-clogging toner outlet, including a cartridge body 1 and a toner outlet 4. One end of the cartridge body 1 is equipped with a first end cap 2, and the other end of the cartridge body 1 is equipped with a second end cap 3. A toner filling port 5 is opened on the side of the cartridge body 1 near the first end cap 2, and the toner outlet 4 is connected to one side of the cartridge body 1.

[0024] Please see Figures 3-6 A feeding mechanism 8 is installed on the inner side of the box body 1 near the powder outlet 4. The feeding mechanism 8 includes a guide rod 801, a moving block 802, a lead screw 803, and a feeding plate 804. The lead screw 803 is installed on the inner wall of the box body 1 through a bearing. The guide rod 801 is fixed on the inner wall of the box body 1 near the lead screw 803. The moving block 802 is sleeved on the outer side of the lead screw 803 and the guide rod 801. The feeding plate 804 is connected to one side of the moving block 802 and is located inside the powder outlet 4. The surface of the feeding plate 804 has a triangular notch. The moving block 802 and the lead screw 803 are threaded together, and the moving block 802 and the guide rod 801 are slidably sleeved together.

[0025] In practice, existing printer toner cartridges dispense toner through the toner outlet. However, due to the accumulation of toner at the outlet over time, blockages can occur. Since the outlet lacks a structure to disperse the toner, this blockage affects print quality. A solution is to connect the stirring shaft 902 to the power unit of an external printer. The stirring shaft 902 drives the first gear 901 to rotate in both directions, which in turn drives the second gear 903 to rotate. The second gear 903 then drives the lead screw 803 to rotate in both directions. The lead screw 803 meshes with the moving block 802, causing the moving block 802 to move left and right on the outside of the lead screw 803. At the same time, the moving block 802 slides on the outside of the guide rod 801. The moving block 802 then drives the feeding plate 804 to move left and right inside the toner outlet 4. This can disperse the toner accumulated in the toner outlet 4 while discharging the toner, preventing the toner from accumulating for a long time and clogging the toner outlet, thus improving the toner cartridge discharging efficiency and printing quality.

[0026] Please see Figures 1-5 One end of the feeding mechanism 8 is connected to a transmission mechanism 9. The transmission mechanism 9 includes a first gear 901, a stirring shaft 902, and a second gear 903. One end of the lead screw 803 is fixedly connected to the second gear 903. One side of the second gear 903 is meshed with the first gear 901. The stirring shaft 902 is fixedly sleeved inside the first gear 901. A connecting rod 6 is fixedly connected to one end of the stirring shaft 902 near the inside of the box 1. A first stirring paddle 7 is connected to the inside of the connecting rod 6. A second stirring paddle 10 is fixed to the outside of the connecting rod 6. The second stirring paddle 10 is designed as a spiral structure and is sleeved on the outside of the stirring shaft 902. One end of the stirring shaft 902 is located outside the first end cover 2. The first gear 901 and the second gear 903 are both located in the built-in groove of the first end cover 2.

[0027] In practice, while the feeding mechanism 8 pushes the toner powder apart, the stirring shaft 902 drives the first stirring paddle 7 and the second stirring paddle 10 to rotate simultaneously. The second stirring paddle 10 is located outside the first stirring paddle 7 and has a spiral structure, which can push the toner powder to rotate. The first stirring paddle 7 stirs and disperses the toner powder in the middle position to prevent clumping. Furthermore, the cooperation between the first stirring paddle 7 and the second stirring paddle 10 can reduce the dead corners caused by toner powder accumulation, improve the uniformity of toner powder mixing, and enhance the practicality of the toner box.

[0028] Working principle: When using this printer toner cartridge with anti-clogging toner outlet, first install the toner cartridge into the drum unit and connect the stirring shaft 902 to the power unit of the external printer. Then, the transmission mechanism 9 drives the feeding mechanism 8 to move, causing the feeding mechanism 8 to push away the toner accumulated in the toner outlet 4, preventing the toner outlet 4 from becoming clogged. At the same time, the stirring shaft 902 drives the first stirring paddle 7 and the second stirring paddle 10 to rotate, stirring and mixing the internal toner to prevent toner from clumping and improving the practicality of the printer toner cartridge. The contents not described in detail in this instruction are existing technologies known to those skilled in the art.
