Abstract: This invention discloses an atomizer for hairdressing which generates micro-size liquid particles by means of electricity-mechanical power conversion elements as a source of ultrasonic wave. The atomizer for hairdressing of this invention intakes air and forcibly send it into a path made of an elastic member. Then it generates minute-diameter liquid particles from the surface of a stored liquid by means of the vibration of the electricity-mechanical power conversion means. Those liquid particles are heated and inducted into the above-mentioned path. The micro-size liquid particles having a diameter of several .mu.m or less generated by the ultrasonic vibration can be controlled at a predetermined temperature. Moreover, the particles can be blown out independently or with hot or cool air.
