Title:
LIQUID AGENT COATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/230805
Kind Code:
A1
Abstract:
[Problem] To provide a liquid agent coating device capable of supplying a liquid agent smoothly from an inflow path to a pressure chamber. [Solution] This liquid agent coating device 100 comprises a pressure chamber plate 8, a diaphragm 7, and a pressurization drive unit 2. The pressure chamber plate 8 comprises a pressure chamber 82 for storing the liquid agent, an inflow path 81 communicating with the pressure chamber 82, and a nozzle 83 communicating with the pressure chamber 82. The diaphragm 7 is disposed above the pressure chamber plate 8. The pressurization drive unit 2 applies pressurized vibrations onto the diaphragm 7. The ratio of the flow path resistance of the nozzle 83, over the flow path resistance in the inflow path 81, is 1 or greater.
