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-type 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, and Usually, the toner bin and developing roller are arranged in the printer casing. When replacing the toner bin, you need to open the cover at the corresponding position on the printer, which is inconvenient to operate. You need to open the printer cover and then take out the toner bin.

Abstract

The invention relates to a toner bin structure of a laser printer. The structure can be detachably embedded in a printer shell and can be matched and butted with a toner cartridge main body, and comprises a toner bin box internally provided with a cavity, the toner cartridge main body is provided with a toner bin for toner in the toner bin box to enter, and a toner inlet is formed in the bin wall of the toner bin; and a toner outlet which can be matched and opposite to the toner inlet is formed in the toner bin box. According to the toner bin structure of the laser printer, the toner bin can be independently replaced, a user can conveniently and independently fill powder, and the toner bin box can be directly replaced at low cost.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a powder bin structure of a laser printer. 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 toner cartridge as a whole or refill it by himself after using 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 the developing roller are...
