Anti-leakage powder device for toner cartridge refilling

Abstract

The invention discloses an anti-leakage powder device for adding powder to a toner cartridge. The toner cartridge has a powder storage bin, and a ring of locking protrusions is arranged on the inner wall of the toner storage bin. The anti-leakage powder device is detachably pressed against the top of the protrusion. Including: connecting pipe, the first supporting net is horizontally clamped inside; the first powder leaking tube, the second supporting net is horizontally clamped inside; the second powder leaking tube is connected with the first powder leaking tube; the plugging component , including a support column, a limit plug, a sealing plug, and a first spring fixed in sequence from bottom to top; a bracket, including a pair of L-shaped struts, a pair of connecting rods, and a positioning frame; wherein, the first powder leakage pipe The upper end is provided with an internal thread that matches the mouth of the toner bottle. When the positioning frame is pressed down, the lower end edge of the second powder leaking tube abuts against the limit tab, and the toner in the toner bottle enters the toner storage bin. The invention has simple structure and convenient use, realizes pollution-free powder feeding, can stop powder feeding immediately at any time, has no carbon powder leakage, and has high powder feeding efficiency.

Description

technical field [0001] The invention relates to the technical field of printer toner cartridges. More specifically, the present invention relates to a powder leakage prevention device for toner cartridge filling. 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 and cause pollution. If the toner powder enters the toner storage bin, if the distribution ...

Problems solved by technology

The toner cartridges used in the existing laser printers on the market are mostly disposable and discarded after use, which makes the cost of office printing 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 and cause pollution, and if the toner powder enters the toner storage bin, if the distribution is uneven, it will lead to partly clear and partly unclear writing on the printing place, which will affect the printing quality
