Abstract: 유체구동장치는, 노즐부, 구동부, 멤브레인을 가진다. 노즐부는 잉크챔버와 노즐공 구비하고 있다. 구동부는 작동유체챔버와 발열체를 구비하고 있다. 멤브레인은 잉크챔버 및 작동유체챔버간을 구획한다. 잉크챔버와 작동유체챔버는 상호 연통되어 있다. 따라서, 잉크챔버와 작동유체챔버 모두에 잉크가 충진되어, 작동유체챔버에 충진된 잉크가 작동유체로서 기능을 한다. 발열체의 발열 작동시 작동유체챔버 내의 압력상승에 멤브레인이 만곡되어 잉크챔버 내부를 가압하며, 이때 노즐공을 통해 잉크챔버 내의 잉크가 분사된다. 본 발명에 따르면, 별도의 작동유체를 마련할 필요가 없고, 작동유체챔버의 실링공정이 필요없으며, 오동작이 발생하지 않게 된다.

Abstract: An ink-jet printhead is provided. The ink-jet printhead includes: a substrate, on the rear surface of which a channel having a bottom is formed with a predetermined depth, wherein a plurality of ink feed holes are formed on the bottom of the channel; a nozzle plate which is coupled to a front surface of the substrate and on which a plurality of chamber-orifice complex holes are formed, wherein each chamber-orifice complex hole corresponds to one or more ink feed holes among the plurality of ink feed holes; and a plurality of heaters which is formed on the front surface of the substrate corresponding to the chamber-orifice complex holes, respectively. Accordingly, the ink-jet printhead can effectively increase ink ejection pressure by effectively suppressing a back flow of ink, while providing for a high resolution image by making the volume of a droplet uniform or very small. Further, the ink feed hole is provided for each chamber-orifice complex hole, thereby preventing degradation in the physical strength of the substrate. In particular, the structure of a channel for supplying ink is significantly simplified.
