However, it is known that the print output device will consume the ink in the ink tank quickly in order to cope with a large number of diverse printing jobs. In addition, the ink storage capacity of the ink tank is limited, so a new ink tank must be replaced soon. At present, the common replacement method is to discard the old ink cartridge and install a new ink cartridge to provide ink. This will inevitably interrupt the printing work, which is very inconvenient for users who need to print a lot, and it will cause ink cartridge damage in the long run. The waste of the body is not in line with the concept of environmental protection. Therefore, in order to save printing costs and avoid waste of resources, a continuous ink supply system that reuses the same ink cartridge was born accordingly.

Existing continuous ink supply systems are all external continuous ink supply systems. An ink supply container is arranged outside the inkjet printer, and the ink is guided from the ink supply container to the nozzle through one or several ink supply pipes. In the ink cartridge of the ink printer, the ink is introduced from the ink supply container into the ink cartridge by using the principle of vacuum guide ink, and then the ink consumption of the ink supply container is visually observed to replenish the ink into the ink supply container in time, which is convenient The purpose of continuous ink supply with uninterrupted ink supply from the ink cartridge can be achieved.
