Liquid jet printing head and method for manufacturing the same
The present invention provides a liquid jet printing head, a method of manufacturing the same, and a liquid jet printing apparatus, which allow stable, high speed, and continuous printing. A liquid jet printing head provides an inflow of liquid from an inlet to a common chamber, then along with the surface of heating elements of a heating element substrate and with a wall of a housing to separate channels. Liquid drops will be ejected by heating the heating elements. Since liquid may flow linearly from the inlet to the separate channels in accordance with the present invention, smooth flow promotes evacuation of bubbles through a nozzle, while cooling the heating element substrate with liquid flowing along with the substrate. The present invention provides thereby stable printing with high speed, continuous ejection (printing) of liquid drops.
