LIQUID VENTING HEAD AND METHOD FOR VENTING LIQUID

摘要

PURPOSE: A liquid venting head is provided to vent a liquid through a vent port by using an energy generated by a generation of a bubble and to limit an upper stream growth of the bubble for stabilizing the vent of the liquid. CONSTITUTION: A liquid venting head includes:a substrate(1) and a ceiling plate(2) being fixed together in a laminated state; a flowing passage(3) being located between the substrate and the ceiling plate; the long flowing passage being surrounded by the device substrate, a side wall(7), and the ceiling plate; single recording head containing plural flowing passages being arranged; a common liquid chamber(6) with a large volume being arranged in an upper stream for being connected to the plural flowing passages simultaneously; and a movable member(11) being attached to the device substrate for being corresponding to a first heating main body(10) and to plural flowing passages.
