INK SPRAYER OF INK-JET PRINTER HEAD

PURPOSE: An ink sprayer of an ink-jet printer head is provided to increase printing quality and reliability by improving a liquid metal injecting method, an installation structure and a testing method. CONSTITUTION: In forming magnetic force by a magnet(60), an electrode unit supplies current to a terminal(40) through a liquid metal(110). The liquid metal changes volume for giving impact on ink(100). The ink forms an ink drop(101) through a spraying hole(11) as much as volume change. The liquid metal is continuously supplied to each liquid metal channel through a main liquid metal channel connected to a liquid metal store tub. Even when Ink is filled up to the area of the liquid metal, the liquid metal store tub pressurizes the liquid metal to the standard value. Thus, the liquid metal is regularly supplied to each liquid metal channel. COPYRIGHT 2000 KIPO ...
