发明名称 THE PRESSURE SELF-ADJUSTMENT EQUIPMENT ATTACHED TO THE INK FEED UNIT FOR EXTERNAL INSTALLATION OF A PRINTER
摘要 PURPOSE: An automatic pressure controlling device embedded in an external ink supply device for a printer is provided to always and regularly maintain ink pressure actuated between a backflow prevention device and a head, thereby automatically preventing the malfunction of the printer caused by a pressure increase. CONSTITUTION: An automatic pressure controlling device embedded in an external ink supply device for a printer includes an automatic ink pressure controlling member (500). The automatic ink pressure controlling member is installed on an ink supply hose (200) between a backflow prevention device and a head (300). When the ink pressure between the backflow prevention device and the head is increased, the automatic ink pressure controlling member decreases the ink pressure by sucking some of ink. When the ink pressure between the backflow prevention device and the head is decreased, the ink is automatically discharged so that the ink pressure is always and regularly maintained. The automatic ink pressure controlling member is composed of a vacuum pack type pressure controller (510). The vacuum pack type pressure controller enables a breathing exercise which is expanded convexly when ink is sucked and shrank to be flat and vacuum-seals a thin synthetic resin film.
