Abstract
An ultrasonic hair curling device capable of applying ultrasonic vibration efficiently to hairs for effective hair styling in a short time. The device includes a housing, an ultrasonic generator incorporated in the housing for generating ultrasonic vibrations, and a horn connected to receive and transmit the ultrasonic vibrations. The horn is formed at its end with a hollow barrel which projects from the housing for receiving therearound a strand of hair to be curled. The hollow barrel is provided at a portion intermediates at its longitudinal ends with a hair winding zone of which cross-section is smaller than the other portion of the hollow barrel. The hair winding zone of the reduced cross section can vibrate at an amplitude larger than at the front end of the barrel for applying the ultrasonic vibrations efficiently to the hair and making the hair curling effectively.
