A kind of regenerated ink cartridge toner sealing part for inkjet printer

Abstract

The invention discloses a renewable ink box carbon powder sealing part for an ink-jet printer. The renewable ink box carbon powder sealing part structurally comprises a top cover, a sealing part bodyand an ink box body. The top cover is fastened on the ink box body. The sealing part body is installed on the top cover and comprises a rotary set, a sealing ring, a self-adaptive adjusting set, a notch patch assembly and a fixed disc. Compared with the prior art, the renewable ink box carbon powder sealing part has the beneficial effects that the sealing ring can be attached to the wall of a powder filling opening all the time; when the sealing ring shrinks, on the basis of the characteristics of a clockwork spring and a spring, jacking force can be generated to the sealing ring to open the sealing ring, thus the sealing ring can be in attached contact with the wall of the powder filling opening completely, leakproofness of the sealing part is further improved, a gap between the powder filling opening and the sealing ring is prevented effectively, the influence of air leakage on normal printing of the printer is prevented, thus printed files are clear and distinct, quality can be ensured, carbon powder can also be prevented from being scattered in the air, and a good usage environment can be provided.

Description

technical field [0001] The invention relates to the technical field of ink cartridges, in particular to a toner sealing member of a regenerated ink cartridge for an inkjet printer. Background technique [0002] Ink cartridges are very important for the entire inkjet printer, and the price of ink cartridges is relatively expensive. In order to save the cost of consumables, after the toner inside the ink cartridge is used up, the ink cartridge is recycled and filled with toner to become a recycled ink cartridge. Therefore, it is necessary to seal the powder filling hole. [0003] The material of the existing ink cartridge toner seals is made of rubber material. The rubber will retract under long-term use and cause a gap at the sealing port. The gap will cause air leakage, which will affect the printing of the printer and may cause the printout At the same time, the gap will cause air injection to cause the suspension of toner, and the particles of toner are generally measured...

Problems solved by technology

[0003] The material of the existing ink cartridge toner seals is made of rubber material. The rubber will retract under long-term use and cause a gap at the sealing port. The gap will cause air leakage, which will affect the printing of the printer and may cause the printout At the same time, the gap will cause air injection to cause the suspension of toner, and the particles of toner are generally measured in microns. If they are scattered in the air, they will be invisible, which will cause damage to the use environment. Pollution
