[0002] The toner cartridge, also known as the photosensitive drum, is typically composed of a base aluminum substrate coated with a photosensitive material. In laser printers, over 70% of the imaging components are concentrated in the toner cartridge, and print quality is largely determined by the toner cartridge.

[0003] The existing authorization announcement number is CN213843779U3, which discloses a toner cartridge with a dustproof structure. The toner cartridge includes a shell, with fixed bases fixedly connected at both ends of the shell. The upper inner portions of the two fixed bases are rotatably connected to protective covers.

A charging roller is installed on one side of the drum core, and a scraper is correspondingly provided on the other side of the drum core. The upper end of the scraper is fixedly connected to a tool holder. This toner cartridge with a dustproof function, when the dust collection device and the exhaust fan are in operation, absorbs floating dust inside the toner cartridge through the dust hood. The absorbed dust is filtered through the dust collection net and is absorbed and intercepted by the two layers of dust collection net. The air is discharged from both sides of the exhaust fan and discharged to the outside of the toner cartridge through the exhaust port, which facilitates dust protection inside the toner cartridge and is beneficial for the use of the toner cartridge.

[0004] Although the above device absorbs the floating dust in the toner cartridge through the dust hood, the absorbed dust is filtered through the dust net and is adsorbed and intercepted by two layers of dust nets. The air is discharged from both sides of the exhaust fan and discharged to the outside of the toner cartridge through the exhaust port. However, if a certain reasonable structural design and material selection can be designed while preventing dust and filtering to reduce the vibration and vibration of the toner cartridge during use, the disturbance and accumulation of dust inside it can be reduced, thereby achieving a certain dust removal effect. For this reason, we have proposed a toner cartridge with a dust-proof structure. Utility Model Content
