Description

Refillable ink cartridge

This case relates to an ink cartridge suitable for an ink jet lister, and more particularly to an ink cartridge which can be refilled with ink.

Because of its simple operation and convenient printing, the inkjet list machine is widely loved by consumers. After using the inkjet lister for a period of time, when the ink in the internal ink cartridge is exhausted, it needs to be replaced with a new one. Ink cartridges are replaced, and the ink cartridges that are replaced are often discarded directly. However, the ink cartridges that are replaced are usually only ink-free for printing, and other ink cartridges, nozzles, wafers, etc. are not necessarily lost at the same time. Not only is it not environmentally friendly, it also wastes a lot of ink cartridges that are not damaged or sustainable.
