Abstract

The invention discloses a leak-proof powder toner cartridge, which has a powder storage bin, and an automatic powder feeder is arranged on the powder storage bin, which includes: a connecting sleeve, which includes an outer sleeve and an inner sleeve arranged coaxially, and the inner sleeve is symmetrically arranged. There are a pair of positioning holes, and the first supporting net is horizontally clamped in the inner casing; the bracket includes a pair of L-shaped struts, a pair of telescopic connecting rods and a positioning frame; the powder adding device includes a vertical powder leakage pipe , a blocking piece arranged at the lower end of the powder leakage pipe, a pair of connecting arms symmetrically and vertically arranged about the axis of the powder leakage pipe, and a support column passing through the blocking piece; With matching internal threads, the positioning frame is pressed down to drive the sealing member to move downward, so that the toner in the toner bottle leaks to the toner storage bin through the gap between the powder leakage tube and the sealing member. The invention has the advantages of simple structure design, convenient use, easy operation, no carbon powder leakage, high powder adding efficiency, high efficiency and environmental protection.

Description

technical field [0001] The invention relates to the technical field of printer toner cartridges. More specifically, the present invention relates to a leak-proof toner cartridge. Background technique [0002] Because of its fast and high-definition printing quality, laser printers occupy an increasingly important position in daily office printing devices. In laser printers, the toner cartridge, one of the core components, carries the key to the electrostatic latent image in the laser printing process. Task. The toner cartridges used in existing laser printers on the market are mostly disposable and discarded after use, which makes office printing costs higher, and then there are separate toner cartridges that can add toner multiple times. When adding toner, due to The toner powder is very fine, and if it is handled improperly, it is easy to leak out, cause pollution, or adhere to the charging roller and affect the printing quality. Therefore, it is very necessary to devel...
