Abstract:
An ultrasonic wave cosmetic device for treating skin, comprising:a probe head having a skin contact metal surface for contacting the skin to transmit an ultrasonic wave to the skin, the probe head having a cup-like opening on a side opposite to the skin contact metal surface;an ultrasonic wave vibration element mounted in the cup-like opening in the probe head for generating the ultrasonic wave by vibrating at an ultrasonic wave frequency in response to an output signal from an ultrasonic wave oscillation circuit; anda temperature sensor mounted in a space between the ultrasonic wave vibration element and an inner wall of the cup-like opening in a manner directly contacting both a side surface of the ultrasonic wave vibration element and a surface opposite to the skin contact metal surface for detecting a temperature of the probe head and supplying a detection signal to the ultrasonic wave oscillation circuit, for controlling the output signal of the ultrasonic wave oscillation circuit to maintain the temperature of the probe head lower than a predetermined level.
