ULTRASONIC ATOMIZATION DEVICE

摘要

The present invention is an ultrasonic wave atomizing device including: a liquid absorbent wick (22) for absorbing a solution from a solution container; and a vibrating plate (32) which has multiple micropores (36) penetrating the vibrating plate (32) in a thickness direction and is for atomizing the solution which has been supplied via the liquid absorbent wick (22) by vibration of a piezoelectric element (31), the vibrating plate (32) includes a truncated-cone-shaped convex part (37), and the solution is a solution in which at least an organic solvent and an active ingredient are mixed and whose viscosity is 1.7 mPa·s (20° C.) to 5.0 mPa·s (20° C.). This structure makes an atomizing height higher, which improves diffusibility of atomized liquid.
