Description

Universal powder leakage prevention toner cartridge

Technical Field

The utility model relates to the technical field of printer parts, in particular to a universal toner cartridge for preventing toner leakage.

Background

The toner cartridge, also called a photosensitive drum, is generally composed of a base substrate made of aluminum and a photosensitive material coated on the base substrate, in a laser printer, more than 70% of image forming components are concentrated in the toner cartridge, the quality of printing is actually determined by the toner cartridge to a great extent, and the photoconductive drum, the magnetic drum and the toner cartridge are integrated into the toner cartridge. The toner cartridge is mainly characterized in that a toner cartridge and a photosensitive drum are arranged on the same device in design, when the toner is used up or the photosensitive drum is damaged, the whole toner cartridge is scrapped, the separated toner cartridge and the photosensitive drum are respectively arranged on different devices, the general service life of the photosensitive drum is very long, the service life of twenty thousand sheets of toner can be generally printed, and only the consumed toner needs to be replaced, so that the printing cost is greatly reduced;

in the process of implementing the utility model, the inventor finds that at least the following problems in the prior art are not solved:

1. when characters printed by the printer are unclear, the quantity of the ink powder in the toner cartridge is possibly insufficient or the ink powder is deteriorated, a user only needs to add a proper amount of new ink powder into a powder bin to restore the normal work of the printer, but the traditional toner cartridge is extremely troublesome to replace the ink powder, the replacement opening is small, the ink powder is easily scattered on other parts of the toner cartridge during replacement, when the ink powder is scattered on a drum core or other parts and is not cleaned, a plurality of black marks are easily formed on the printed characters to influence the printing quality, and because the filling opening is small, the user cannot observe the quantity of the internal ink powder, the injected ink powder is easily too much or too little to influence the use experience, meanwhile, the sealing structure of the powder filling opening of the traditional replaceable toner cartridge is mostly a piston type sealing mechanism, the sealing mode is easy to cause the untight sealing after the traditional toner cartridge is used for a long time, the ink powder is easy to fall off, so that the ink powder in the powder bin falls off to influence the printing quality, and the whole ink powder needs to be improved;

2. after traditional selenium drum used for a long time, the volume of toner can be less and less, just can make the characters that print not clear enough, need regularly inject new toner this moment, before injecting new toner, need add new toner with the inside toner clean-up in powder storehouse usually, no person can influence the quality of printing, when traditional selenium drum cleared up waste powder, discharge waste powder from annotating the powder mouth usually, when waste powder in the powder storehouse was wet owing to the leakproofness is not good, hard block easily becomes, then hardly discharge waste powder from less notes powder mouth, influence the normal use of selenium drum, dismantle the maintenance and can spend a large amount of funds, traditional selenium drum lacks waste powder clearance mechanism, whole remains to be improved.

Therefore, the powder leakage prevention universal toner cartridge is provided.
