Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a carbon powder box with a novel drum core and a conductive positioning structure of a developing roller. Background Art

[0002] There is an existing toner cartridge, which has multiple sets of tension springs installed on the outer side of an integrated conductive inner cover. These tension springs not only have the responsibility of physically fixing the drum core and the developing roller, but also play the role of conducting current to the printing component. This design is achieved through the oblique hollow holes on the integrated conductive outer cover and the tension spring positioning parts that match it. Specifically, during the assembly process, the tension springs are cleverly embedded in the oblique hollow holes and tightly connected to the positioning parts, thereby ensuring the stable positioning of the drum core and the developing roller, while ensuring that the current conduction path is unobstructed.

[0003] However, this original design also has its limitations: first, although the coordination mechanism between the tension spring, the oblique hollow hole and the positioning piece realizes the basic functional requirements, during long-term use or frequent replacement, the elastic fatigue of the tension spring may lead to a decrease in positioning stability, thereby affecting the printing effect; secondly, the original design did not take into account the sustainable use of the toner cartridge and lacked a convenient powder filling port design, which restricted the user's repeated filling of toner, increased the user's use cost, and was not conducive to resource conservation and environmental protection.

[0004] Therefore, it is imperative to redesign a toner cartridge with a new conductive positioning structure of the drum core and the developing roller. Utility Model Content

[0011] Furthermore, a spring fixing column is provided at one end of the front edge support platform close to the integrated conductive outer edge cover, and the positioning spring is provided on the spring fixing column. A spring positioning cross column is provided at one end of the front edge positioning platform close to the integrated conductive inner edge cover, and when the waste powder bin and the powder bin are assembled, the spring positioning cross column is positioned at the other end of the positioning spring.
