Background technique

Ordinary ink cartridges generally use two methods to fill ink. The first is the negative pressure ink filling method, which means that all the air inside the ink cartridge is drawn out, and the ink is sucked into the ink cartridge due to the suction inside the ink cartridge. This method is mostly used for sponge ink cartridges and soft bags. Ink cartridges, etc.; the second is the positive pressure ink filling method, that is, the ink is injected into the ink cartridge by pressure, and the air in the ink cartridge is discharged. This method is mostly used for refillable ink cartridges or continuous supply products. Since the ink filling object is a single-ink chamber ink cartridge, a one-way ink filling method is adopted. However, with the continuous development of printing consumables technology, double ink chamber ink cartridges have begun to occupy the market. The double ink chamber ink cartridges have ink chamber Ⅰ and ink chamber Ⅱ, which are connected through the flow channel at the bottom of the ink cartridge. The pressure of the ink outlet also plays the role of constant pressure, thereby improving the stability of printing. Double-chamber ink cartridges are widely used because of their superior performance. However, in the prior art, the original one-way negative pressure or one-way positive pressure ink filling method is still used for the ink filling of this double-chamber ink cartridge. method, but these two methods cannot fill the ink chamber when filling ink, and there is air in the ink chamber, causing poor ink filling, which in turn leads to low product qualification rate and poor printing effect.
