LIQUID DISCHARGE DEVICE AND LIQUID DISCHARGE METHOD

摘要

A discharging means (101) comprises: an elastic discharge part (105) including a storage chamber (110) at least partially formed of an elastic member (113), a supply hole (116) for supplying a liquid (201) into the storage chamber (110), and a discharge hole (117) for discharging the liquid (201); and an actuating means (114) for varying the volume of the storage chamber (110). In addition, the discharging means (101) comprises: a pressurizing means (102) for pressurizing the liquid (201) so that the pressure of the liquid (201) supplied into the storage chamber (110) is greater than atmospheric pressure; a supply control means (103) for determining whether to supply the pressurized liquid to the storage chamber (110); and an actuation control unit (104) for controlling the actuating means (114).
