Description

Technical Field

[0001] The utility model relates to the technical field of selenium drums, in particular to a selenium drum photosensitive structure. Background Art

[0002] Toner cartridges, also known as toner cartridge bodies, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. Toner cartridges not only determine the quality of printing, but also determine how much money users need to spend during use. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the quality of printing is actually largely determined by the photosensitive structure on the toner cartridge.

[0003] Most of the photosensitive structures on traditional toner cartridges are light-conducting materials. When the photosensitive semiconductor on the light-conducting material is exposed to light, it cooperates with the conductive roller to generate conductivity, which will change the "carrier mobility" of the object to varying degrees, which is equal to the carrier density multiplied by the forward mobility. As the mobility increases, the conductivity increases, and the conductivity of the light-conducting material is proportional to its sensitivity to light. When the toner cartridge cooperates with the conductive roller to print materials, it is necessary to dip the toner cartridge powder through the light-conducting material as the toner cartridge rotates to cooperate with printing. When toner cartridge powder remains on the surface of the light-conducting material, the conductivity effect of the light-conducting material is reduced. When the conductive roller cooperates with the light-conducting material on the toner cartridge to print, the residual toner cartridge powder will cause the conductivity of the light-conducting material, which will cause the printing to be clumped, unclear, and disconnected.

[0004] The existing patent (publication number: CN 116893594 A) discloses a toner cartridge photosensitive structure, including a toner cartridge roller shaft, wherein a vertically elastic toner cartridge powder cleaning component is arranged below the light guide layer outside the toner cartridge roller shaft, so that when the toner cartridge powder cleaning component cooperates with the toner cartridge roller shaft to rotate, the top of the toner cartridge powder cleaning component contacts the outer wall of the light guide layer, and the toner cartridge powder remaining on the outer wall of the light guide layer after printing in cooperation with the conductive roller is contacted and cleaned. During the rotation of the light guide layer, the toner cartridge powder cleaning component moves downward after encountering an obstacle resistance as the force generated by the rotation, and then bounces upward to the light guide layer again after moving downward, so as to achieve the purpose of vibrating the light guide layer to clean the toner cartridge powder. A horizontal card plate is arranged outside the connecting plate on the toner cartridge photosensitive structure, so that the horizontal card plate outside the connecting plate is horizontally connected with the card slots on both sides of the toner cartridge roller shaft area inside the toner cartridge body, and the card slots in the card slots are connected by the spring buckles on the upper surface and the bottom surface of the horizontal card plate, so as to achieve the fast and stable fixing of the toner cartridge photosensitive structure on the toner cartridge body.

[0005] However, the above technical solution still has certain defects. When the drum roller rotates, the auxiliary carbon powder on the outer wall of the drum is cleaned by a scraper. However, when the scraper is used, it cannot be guaranteed that the scraper is in close contact with the outer wall of the drum, resulting in incomplete cleaning of the drum. For this reason, a drum photosensitive structure is proposed. Utility Model Content
