Document Type and Number:
WIPO Patent Application WO/2019/064781
Kind Code:
A1
Abstract:
[Problem] To provide a liquid agent discharge apparatus capable of smoothly discharging a liquid agent with a simple configuration. [Solution] A liquid agent application apparatus (10) is provided with a head (18) and a second piezoelectric element (14). The head (18) has: a liquid agent storage section (11) including a pressure chamber (11e) and a discharge port (11h); a diaphragm (12) which changes the volume within the pressure chamber (11e); and a first piezoelectric element (13) which applies pressure to and vibrates the diaphragm (12). The second piezoelectric element (14) is attached to the head (18). A first stretching direction D1 of the first piezoelectric element (13) intersects a second stretching direction D2 of the second piezoelectric element (14).
