Title
(EN) LIQUID APPLICATION DEVICE
(FR) DISPOSITIF D'APPLICATION DE LIQUIDE
(JA) 液体塗布装置
Abstract
(EN)
[Problem] To provide a liquid application device in which pressure in a liquid storage unit for supplying liquid to a discharge unit which discharges the liquid can be quickly set to a predetermined negative value. [Solution] A liquid application device 1 has: a liquid storage unit 10 for storing liquid; a pressure sensor 26 for detecting the amount of the liquid remaining in the liquid storage unit 10; a discharge unit 30 for discharging the liquid within the liquid storage unit 10 to the outside; a negative pressure pump 22a for generating a negative pressure lower than the atmospheric pressure; a negative pressure regulation container 22b, the inside of which is regulated to a predetermined negative pressure by the negative pressure pump 22a; a pressure regulation control unit 61 for controlling the drive of the negative pressure pump 22a on the basis of the result of detection by the pressure sensor 26; and a pressure switching unit 50 capable of switching pressure in the liquid storage unit 10 to the predetermined negative pressure in the negative pressure regulation container 22b.
