Description

  The present invention relates to an ultrasonic cosmetic device using ultrasonic waves.

  Conventionally, a skin treatment called so-called peeling that chemically or mechanically removes aging skin is known. Patent Document 1 is known as an apparatus that performs peeling by a mechanical method.

  The ultrasonic beauty apparatus described in Patent Document 1 has a probe in which a plurality of ultrasonic vibrators are attached to a vibration plate, and the vibration plate is vibrated by the ultrasonic vibrator, and ions of the vibration plate are used. Skin treatment such as peeling and tapping is performed by applying the introduction part to the skin. The diaphragm is made of metal and can be applied with a pulsating current. By applying the hand electrode provided on the probe and the diaphragm to the skin, an iontophoretic treatment can be performed.

  In order to perform such treatment, it is necessary to vibrate the tip of the diaphragm with sufficient displacement. In order to obtain the required vibration, it is necessary to apply a large amount of power to the ultrasonic element. However, if a large amount of power is applied, the vibrator will generate heat and the vibration will weaken over time, resulting in sufficient vibration of the diaphragm. There is a problem that the entire probe has heat due to heat generation.

  In the ultrasonic beauty apparatus described in Patent Document 1, a plurality of ultrasonic vibrators are attached to a vibration plate to obtain a desired displacement vibration and to improve the heat dissipation function. As a result, the probe has become larger and the degree of freedom in design, such as downsizing, has been limited. In addition, the use of a plurality of ultrasonic transducers complicates the circuit, so that there is a problem that the main body becomes larger and the manufacturing cost increases due to the power supply and circuit arrangement space.

In addition, when performing iontophoretic treatment, the iontophoretic portion of the diaphragm has a small area that touches the skin, so that an efficient treatment could not be performed.

  The present invention can realize an efficient treatment by introducing ions, suppress the generation of heat while ensuring sufficient displacement vibration, achieve a desired skin beautifying effect, reduce the size of the device, and improve the degree of freedom of design. An object of the present invention is to provide an ultrasonic cosmetic device that can be economically advantageous while keeping costs low.
