Abstract

본 발명은 잉크젯 프린터의 분사 장치 및 분사방법에 관한 것으로, 보다 상세하게는 개별전극에 전달된 전기적 에너지에 의해 히터부를 가열하고, 그 열에 의해 열팽창하는 액체 및 기체를 이용하여 멤브레인을 유동시키고 상기 멤브레인의 유동에 따라 잉크를 미디아로 분사시키는 잉크젯 프린터의 분사장치 및 분사방법에 관한 것이다.More particularly, the present invention relates to an ink jet printer and a method of injecting ink, and more particularly, to a method and apparatus for heating a heater by electrical energy transmitted to an individual electrode and using the liquid and gas thermally expanding by the heat to flow the membrane, To a jetting device and a jetting method of an inkjet printer which jet ink to a medium according to the flow of the ink.

가열쳄버내의 액체 및 기체의 열팽창을 조절하여 멤브레인의 변형에 따라 잉크를 분사하므로써, 잉크와 히터부가 분리되어 있음에 따라 잉크와 보호막의 접촉에 의한 부식을 방지할 수 있으며, 버블이 생성되어 개구부로 분사될 때 생기는 충격에 이해 보호막이 손상되는 것을 방지할 수 있으며, 버블에 의한 증기압에 의해 분사되지 않고 가열에 의한 멤브레임의 열팽창으로 잉크에 직접 체적 변형을 일으켜 잉크를 개구부로 분사시키므로써 잉크의 재충전이 빨리 이루어지고 결국 고속 프린팅을 기대할 수 있는 효과를 가진다.Since the thermal expansion of the liquid and the gas in the heating chamber is controlled so that the ink is jetted in accordance with the deformation of the membrane, the ink and the heater are separated, so that corrosion due to contact between the ink and the protective film can be prevented, It is possible to prevent the protective film from being damaged due to the impact caused when the ink is jetted, and it is possible to directly cause volume deformation of the ink due to thermal expansion of the membrane due to heating without being sprayed by the vapor pressure by the bubble, Recharging can be performed quickly, and high-speed printing can be expected.
