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.

Ink cartridge refilling device and ink cartridge refilling method utilizing the same for ink refilling

The invention relates to an ink cartridge refilling device and an ink cartridge refilling system. The ink cartridge refilling device comprises an ink container, an ink injection channel, an air inlet channel, an aspirator and a cover component, wherein the cover component is provided with a first sealing section for sealing an ink cartridge to be refilled and a second sealing section for sealing the air inlet channel. During the ink refilling, air in a sealed ink cartridge can be sucked to enable ink in the ink container to flow into the sealed ink cartridge, so that negative pressure is formed in the ink container and the ink is conveyed from the ink container to the ink cartridge under the negative pressure, thus the refilling of the ink into the ink cartridge and the replenishing of air into the ink container may not be carried out at the same time.
