Problems solved by technology

Due to the many internal components of the toner cartridge, the replacement cost is high, and if the user fills the toner cartridge by himself, it is easy to cause powder jams or leakage during printing due to improper operation, which will affect the printing effect or pollute the printed image
However, in the existing split toner cartridge structure, the toner bin and the developing roller are usually separated into one component. When the toner in the toner bin is used up, the toner bin and the developing roller need to be replaced at the same time, and the replacement cost is relatively high.

Abstract

The invention relates to a toner bin opening and closing structure of a split toner cartridge. The structure is arranged in a shell of a printer and comprises a toner supplementing bin detachably butted on a toner cartridge of a toner cartridge body, a toner outlet opposite to a toner inlet in the toner cartridge is formed in the toner supplementing bin, and a sealing piece capable of moving along with a sealing cover on the shell is movably arranged in the toner supplementing bin corresponding to the toner outlet. And the sealing piece and a sealing cover on the machine shell are arranged in a transmission manner and can be closed along with opening and closing of the sealing cover, and the powder outlet is opened. According to the invention, toner supplementing operation can be conveniently carried out, and toner powder in the toner supplementing bin can be prevented from falling, being polluted and going bad during installation.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a powder bin opening and closing structure of a split toner cartridge. Background technique [0002] The toner cartridge mechanism used in the existing laser printer is mainly divided into an integrated toner cartridge structure and a split toner cartridge structure. The one-piece toner cartridge structure integrates the imaging unit and the developing unit in the toner cartridge, and the user needs to replace the whole toner cartridge or refill it by himself after using up the toner in the toner cartridge. Due to the many internal components of the toner cartridge, the replacement cost is high, and if the user fills the toner cartridge by himself, it is easy to cause powder jam or leakage during printing due to improper operation, which will affect the printing effect or pollute the printed image. However, in the existing split-type toner cartridge structure, the toner bin and...
