BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic cosmetic device for performing beautiful skin treatment by transmitting ultrasonic vibrations to a head of a probe that comes into contact with the skin.

[0002]

The ultrasonic wave generates a vibration wave having a strong energy to crush the bacterial cells, peel off the surface layer,
When this vibration wave acts on the skin, it disinfects the surface layer of the skin, exfoliates waste and stratum corneum, and lifts up acne, oil in pores, dirt, and makeup residue. It promotes blood circulation in the surface layer of the skin, activates tissues, and relaxes muscles to remove spots, wrinkles, and tarmi.

[0003] The ultrasonic beauty device performs a beautiful skin treatment by transmitting ultrasonic vibrations to the head of a probe that should come into contact with the skin. Ultrasonic waves are fine vibration waves of 20 kHz or more and are applied to the skin. I can hardly feel the vibration. For this reason, there is no real feeling that the treatment is being performed, and there is no movement felt on the skin, and it is difficult to feel interest and to maintain interest.

On the other hand, ultrasonic waves are greatly attenuated in air,
Even if the ultrasonic vibrator is brought into direct contact with the skin, the air intervenes and energy is not efficiently transmitted to the skin. Therefore, a medium such as gel or cream is applied to the contact surface between the ultrasonic vibrator and the skin to increase the ultrasonic wave propagation efficiency. When the surface of the skin is rubbed with a cleansing cream or the like on this medium, dirt and the like floating on the surface of the skin due to ultrasonic vibration waves can be removed cleanly.

Therefore, the present invention provides a probe for an ultrasonic cosmetic device by providing the surface of the head with irregularities and rotating the probe.

The through holes H1 and H2 are provided with spring pins P1 and
Looking at the end of P2, the spring pins P1 and P2 press the opposed ring electrodes E1 and E2 from the lateral direction to electrically connect the lead wires L1 and L1 'with L2 and L2', respectively. The lead wires L1 'and L2' are focused on the cable 4 and the ends are connected to an ultrasonic oscillator (not shown).

The probe of the ultrasonic friction cosmetic apparatus embodying the present invention is configured as described above, and when performing a treatment, first, a cleansing cream is applied to the treatment site or the tip of the head unit 1. Next, the tip of the head unit 1 is lightly pressed at right angles to the skin surface, and the push switch 23 is turned on to move the probe along the skin surface so as to slowly draw a circle.

When the push switch 23 is turned on, the vibration voltage of the ultrasonic oscillator is applied to the ultrasonic vibrator 14, and the vibrating body 12 undergoes bending deformation and ultrasonically vibrates. As a result, the ultrasonic vibration wave acts to strike the skin surface, exfoliating the old epidermis, and lifting waste, the stratum corneum, or oil, dirt, and makeup residue in pores. In addition, the ultrasonic vibration waves are diffused over a wide area to vibrate the skin surface, thereby promoting blood circulation in the surface layer of the skin and activating the tissue.

At the same time, the geared motor 22 slowly rotates at a speed of about 60 rpm and alternately rotates forward or reverse. When the geared motor 22 rotates forward, the concave curved side of the ridge c on the surface of the vibrating body 12 acts to scrape the skin surface, and cleans and removes dirt such as wastes floating on the skin surface together with the cleansing cream. When the geared motor 22 rotates in reverse, the convex side of the ridge c on the surface of the vibrating body 12 acts so as to hit the skin surface, and the cleansing cream is printed on the skin surface. At the same time, stretch the skin to relieve muscle tension, remove spots, wrinkles, and tarmi,
The pores are opened to reinforce the ultrasonic cleaning action.

Further, the compressor operates to blow air from the tip of the air tube 3, and the air hits the ultrasonic vibrator 14 and is discharged from the air hole A. Thereby, the ultrasonic vibrator 14 is cooled, and the temperature of the vibrating body 12 is kept at a normal temperature by preventing overheating.

As described above, in the ultrasonic friction cosmetic apparatus of the present invention, the head is connected to the probe via the rotation driving means, and the surface of the head has irregularities. Therefore, according to the present invention, since the head rotates, the treatment can be felt and the interest can be maintained. In addition, since the unevenness of the surface of the head rubs the skin, the cream penetrates the skin, and dirt and the like floating on the skin surface are removed together with the cream. Thereby, the beautiful skin effect and the cleaning effect of the ultrasonic wave can be further enhanced.
