Abstract
A simplified refilling assembly of DURABrite ink cartridge comprises an ink bottle connector, a pipe and an ink cartridge connector; the ink cartridge connector has a plug pipe to be connected with the refilling hole of the ink cartridge hermetically; the ink bottle connector is furnished with a L-shaped connector and a recovering cylinder, which are molded into one piece to be plugged into a bottle plug of the ink bottle; the ink cartridge and the ink bottle are connected each other by means of a refilling assembly; a syringe is plugged into the refilling hole of the ink cartridge; when the pull grip is pulled upward, the ink in the ink bottle will be drawn to flow into the ink chamber of the ink cartridge; then, the syringe is plugged into the recovering cylinder of the ink bottle connector so as to recover ink for re-use.
