An ink-refilled convection device for introducing ink into an ink cartridge mainly has an ink-refilled convection unit disposed at the top of taper column of the ink container. When the ink-refilled convection unit is inverted to insert into the ink tank, the drain conduit goes deep into the bottom of the ink tank for the ink flowing into the ink tank. The vent conduit has an end above the ink container and the other end at a predetermined level in the chamber to form a convective circulation between the drain conduit and the vent conduit. Once the ink flows downward in the drain conduit, it starts to fill in the cartridge automatically until the predetermined level is reached, and after that, the convective circulation stops immediately to complete the ink refilling.
