PURPOSE: To completely and efficiently diffuse a slight amt. of perfume by blasting the mist formed by spray of an atomizer adequate as an aroma device for diffusing a slight amt. of perfume into the amt. to a prescribed direction by a blasting means, then further, atomizing the mist by an ultrasonic vibrator transducer.

CONSTITUTION: A depressing button driving shaft 8 depresses a depressing button 3 against a spring 9 when a solenoid 7 is energized. The liquid aroma sealed in a container 2 is then ejected from a nozzle 4 toward a diffusion hole 14. At this time, the atomized perfume is blown off forward by the operation of a blast fan 11. The relatively large particles among the atomized perfume are further atomized by the vibration of the prescribed vibration frequency oscillated by the ultrasonic vibrator transducers 5, 6. The perfume atomized in such a manner is delivered outside from the diffusion hole 14 and is diffused into the atm. An opening/closing cap 13 is opened and is exchanged with the fresh container 2 when the liquid perfume enclosed in the container 2 is used out.
