Ink cartridge and method for injecting ink therein

Abstract

The invention provides an ink cartridge and a method for injecting ink therein. The method comprises forming an ink injection hole in a communication channel of the ink cartridge; injecting the ink into an ink accommodating part through the ink injection hole; and sealing the ink injection hole when ink injection is finished. The ink cartridge and the method for injecting the ink therein prevent the ink from flowing into an air-liquid separation chamber, thereby ensuring the air inlet performance of the air communication channel.

Description

technical field [0001] The invention relates to inkjet printer technology, in particular to an ink box and an ink injection method thereof. Background technique [0002] With the widespread use of inkjet printers, the consumption of ink cartridges is also gradually increasing, and as a consumable, ink cartridges are mostly discarded after use, and these discarded ink cartridges include plastics, films, chips and other components, of which Many components cannot be degraded naturally, resulting in resource waste and environmental burden. In order to reduce the pollution of waste ink cartridges to the environment, the empty old ink cartridges are often recycled and filled with ink again to obtain secondary use value. [0003] A common way to recycle the ink cartridge is to form an ink injection hole on the ink cartridge, and fill the ink container inside the ink cartridge with ink through the ink injection hole. In order to ensure stable ink supply during printing, the inter...

Problems solved by technology

In actual use, it is found that when filling ink through the above-mentioned ink injection hole, since the ink cartridge may rotate during the ink filling process, it is very likely that the ink injected into the ink cartridge will flow backwards in the atmospheric communication channel and flow along the atmospheric communication channel. Moving to the open hole side of the atmosphere, part of the ink will also adhere to the atmosphere communication channel during the backflow process; however, since the atmosphere communication channel is usually set thinner, if the ink cartridge has not been used for a long time, the ink attached to it will become dry. It is easy to affect the air intake performance of the atmospheric communication channel, which in turn affects the printing performance of the ink cartridge, causing printing disconnection and other problems, resulting in poor regeneration of the ink cartridge
