<p>The invention relates to a negative-pressure ink cartridge refilling device, system and method. The device comprises an ink container, an ink injection channel, an aspirator and a suction channel, wherein the ink container is used to store ink conveyed to an ink cartridge to be refilled; one end of the ink injection channel is an inlet end through which ink in the ink container enters into the ink injection channel and the other end of the ink injection channel is an outlet end connected with the ink cartridge to be refilled; the suction channel is communicated with the ink container; a sucking opening connected with the aspirator is formed on the suction channel; and the inlet end is disposed above the ink level surface of the ink container. As the inlet end is disposed above the ink level surface of the ink container, the ink in the ink container cannot be overflowed via the ink injection channel regardless of the environmental factors, and thus the technical problem that the phenomenon of ink splash tends to occur when the traditional negative-pressure ink cartridge refilling device is used by a user for the first time can be solved.</p> |
