Connecting structure of split type toner cartridge

Abstract

The invention relates to a connecting structure of a split type toner cartridge, which is arranged in a printer shell with a cover plate, and comprises a toner cartridge integrally connected to a toner cartridge main body and provided with a toner inlet; a first cover body used for opening and closing the toner inlet; a toner cartridge box which is matched with the toner cartridge, wherein a toner outlet is formed in the toner cartridge box; a second cover body which can open and close the toner outlet; a powder outlet piece which is provided with a first opening hole and is rotationally arranged in the toner cartridge box, wherein along with rotation of the powder outlet piece, the first opening hole and the toner outlet can be overlapped to open the toner outlet or the first opening hole and the toner outlet are staggered to close the toner outlet; a linkage piece connected to the cover plate; and a transmission mechanism which is in transmission association with the powder outlet piece and the linkage piece, and the transmission mechanism can drive the first opening hole of the powder outlet piece to move towards the toner outlet along with the closing action of the cover plate. The connecting structure of the split type toner cartridge is provided with the toner cartridge box independent of the toner cartridge, so that a user can conveniently fill toner by himself or herself or reduce the replacement cost of the toner cartridge, and the toner can be prevented from being scattered in the assembly process.

Description

technical field [0001] The invention relates to the technical field of laser printers, in particular to a connection structure of a split powder bin. 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 the developing rol...

AI Technical Summary

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.
