LIQUID DISCHARGE HEAD, HEAD CARTRIDGE WITH THE SAME, AND LIQUID DISCHARGE APPARATUS

摘要

PROBLEM TO BE SOLVED: To reduce a burden of a body recovery system while preventing using two liquids from mixing and scattering, and further stabilizing the discharge capability. SOLUTION: There are provided a discharge opening for discharging the liquid, a bubble generation region where bubbles generated in the liquid in a liquid channel, and a moving member which is arranged facing the bubble generation region and which can move between a first position and a second position farther from the bubble generation region than the first position. The moving member is a liquid discharge head which moves from the first position to the second position by a pressure based on the generation of bubbles in the bubble generation region and which discharges the liquid by swelling the bubbles larger to the downstream than to the upstream of a direction towards the discharge opening by the movement of the moving member. The liquid channel has at least one of a check valve, a pressure pump and a valve disposed thereto or has a cap fitted to the liquid discharge head for freely opening the discharge opening.
