<p>A negative-pressure filling apparatus, system and method for an ink cartridge are disclosed. The apparatus (1) includes: an ink container (2); an ink filling passage (3) for supplying ink into the ink cartridge (15) to be filled, wherein one end of the ink filling passage is an inlet end (32) through which ink in the ink container is filled into the ink filling passage, and the other end thereof is an outlet end (31) connected to the ink cartridge to be filled; a suction device (12); and a suction passage (4) communicated with the ink container and provided with a suction port (41) connected with the suction device. When the apparatus (1) is placed in a state where it does not fill ink, the inlet end (32) is located above the ink level in the ink container. Therefore, when the apparatus (1) is in above state, no matter how the external circumstance factors change, the ink in the ink container will not overflow through the ink filling passage, which solves the technical problem that ink splashing tends to occur when an existing negative-pressure filling apparatus for an ink cartridge is used for the first time.</p> |
