[0002] The toner cartridge is one of the core components of a laser printer, also known as a photosensitive drum. It is mainly composed of photosensitive materials (selenium or organic photoconductive materials), aluminum drum core, charging roller, developing roller, cleaning blade, waste toner bin and toner bin (refilling bin). Among them, the drum core is the key part, and its surface coating can change conductivity under light, thereby realizing image formation.

[0003] However, it is difficult to overcome the electrostatic adsorption force of waste powder in existing toner cartridges, resulting in a large amount of waste powder adhering to various places inside the toner cartridge, which is difficult to fall off naturally and is extremely difficult to clean up, affecting the waste powder collection work. The waste powder collection speed is slow, and a large amount of waste powder remains, which has many adverse effects on the performance of the toner cartridge, such as reducing the printing quality, uneven colors, blurred printing marks, etc., and will also greatly reduce the overall work efficiency of the toner cartridge, causing frequent failures, increasing the cost of use and the difficulty of maintenance, and it is difficult to meet the needs of efficient and stable printing.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention forms a specific air flow situation in a local area through an exhaust fan and an exhaust pipe, generating a weak suction force. The weak suction force cleverly breaks the situation where waste powder is attached to various places inside the toner cartridge due to electrostatic adsorption and is difficult to fall off. During the printing process, the toner cartridge body uses the powder supplied by the powder adding bin to perform printing operations. When there is residual powder, the airflow environment created by the exhaust fan allows these powders to migrate to the waste powder bin in an orderly manner under the action of weak suction. At the same time, the filter installed at the air outlet of the exhaust pipe blocks the powder from entering the exhaust pipe. The present invention speeds up the waste powder collection speed, reduces the adverse effects of waste powder residue on the performance of the toner cartridge, and improves the overall working efficiency and printing quality of the toner cartridge.

[0025] 2. The present invention uses the scraper of the powder scraping assembly to continuously reciprocate at the air outlet, gradually scraping off the powder that may be accumulated at the air outlet and pushing it into the waste powder bin, so that the air outlet is always unobstructed, and the weak suction force generated by the exhaust fan can play a stable and effective role, and continuously suck the waste powder into the waste powder bin. The present invention not only ensures the efficient collection of waste powder, but also extends the service life of the exhaust fan and the entire powder suction assembly, and reduces equipment failures and maintenance costs caused by blockage of the air outlet.

[0026] 3. The present invention sets a powder conveying drive component to continuously push the powder during the powder adding process, making it easier for the powder to enter the powder adding bin and reducing the probability of blockage. The conveying screw shaft acts as a precise transportation track in the conveying bin, and the axial thrust generated by its rotation continuously acts on the powder, overcoming the obstacles such as the gravity, friction and possible agglomeration of the powder itself, and effectively pushing the powder to flow into the powder adding bin continuously. This continuous and stable powder conveying method greatly optimizes the powder adding process. The present invention not only reduces the blockage caused by powder accumulation and jamming, but also improves the efficiency and accuracy of powder adding.

[0027] 4. The present invention adds a reset shaft, a torsion spring and a push plate to the powder feeding assembly. The push plate always fits closely to the bottom of the powder feeding bin during rotation, effectively combing and pushing the powder at the bottom of the powder feeding bin. The torsion spring enables the push plate to adapt to the different terrain changes at the bottom of the powder feeding bin, ensuring that no matter whether the bottom of the powder feeding bin is flat or not, the push plate can continue to effectively push the powder to every corner evenly, avoiding the accumulation of powder at the bottom of the powder feeding bin or partial vacancies. The present invention not only improves the accuracy and uniformity of powder feeding, ensures the stability of printing quality, but also effectively prevents the problem of poor powder feeding or even blockage caused by powder accumulation.

[0028] 5. The present invention sets fifteen stirring components in the powder adding bin. Due to the interaction between friction and motion trajectory, the stirring rod can rotate along the axis of the roller while revolving. The combination of revolution and rotation enhances the stirring effect of the stirring rod on the powder. The fifteen stirring components work together to stir the powder in the powder adding bin comprehensively and deeply. The present invention can effectively break the agglomeration phenomenon that may exist in the powder, so that powders of different components and different particle sizes are fully mixed and uniform, ensuring that the quality of the powder added into the main body of the toner cartridge for printing is stable and consistent each time, thereby ensuring the accuracy and uniformity of the printed color.

[0068] Working method: The rotating disk 701 is driven to rotate through the connecting shaft 1027 of the sixth gear 1026, and the rotating disk 701 drives the stirring rod 702 to rotate along the axis of the connecting shaft 1027.
