Abstract
The invention relates to an ink cartridge refilling device, which comprises an ink container, an ink injection channel, an air suction channel, an air inlet channel and a leakage-proof component, wherein both the air suction channel and the air inlet channel are arranged inside the ink container; and the leakage-proof component is arranged on the air inlet channel. As both the air suction channel and the air inlet channel are arranged inside the ink container, the ink cartridge refilling device has the advantages of having compact overall structure, small space usage and simple operation, reducing the number of dies in the manufacturing process, fully reducing the manufacturing cost, and solving the technical problems of large space usage, trivial operation and high manufacturing cost in the traditional ink cartridge refilling device.
