Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 skin surface layer, exfoliates waste and stratum corneum, and lifts 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.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to rotate the head of a probe of an ultrasonic cosmetic device so as to give a motion felt to the skin, and to further enhance the beautiful skin effect and the cleaning effect of the ultrasonic wave by friction. It is.

[0006]

In order to achieve the above object, the present invention is configured as follows.

More specifically, in an ultrasonic cosmetic device for performing a beautiful skin treatment by transmitting ultrasonic vibrations to a head of a probe which should come into contact with the skin, the head is connected to the probe via a rotation driving means, and the head is rotated. A rotating probe that rubs against the skin surface.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of a rotary probe embodying the present invention. In the rotary probe, the distal end of a hollow rotary shaft 1 is supported by a bearing 2 that does not require lubrication, and a cylindrical head 3 having a flat distal end surface is attached to the distal end of the rotary shaft 1. Then, the middle part is connected to the geared motor 5 via the bevel gear 4, and the power supply plate 6 is attached to the base. Further, the hollow bearing 7 is inserted with the base end opened.

The head portion 3 is made of a flexible and elastic thin stainless steel plate or a metal such as hard aluminum, duralumin, or thin copper plate, and is subjected to a surface treatment such as hard chrome plating. Also, an ultrasonic vibrator 8 made of piezoelectric ceramics is fixed inside the front end surface of the head portion 3.

FIG. 2 shows a side view of the power supply plate 6. The power supply plate 6 joins the pair of disks 61, 61 by providing a spacer 62, and brings the tips of the pair of contact brushes 63, 63 pressed against the conductive opposing surfaces of the disks 61, 61 by a leaf spring into contact. .
The base ends of the contact brushes 63, 63 are connected to a pair of lead wires 64,
64, and the ends of the lead wires 64, 64 are connected to an ultrasonic oscillator (not shown). Also, the disks 61, 61
The ends of a pair of lead wires (not shown) that pass through the hollow rotary shaft 1 through the conductive opposing surface are connected to both terminals of the ultrasonic transducer 8.

[0012] The rotary probe 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 3. Next, the tip of the head unit 3 is lightly pressed at right angles to the skin surface, the switch is turned on, and the probe is moved along the skin surface so as to slowly draw a circle.

When the switch is turned on, the ultrasonic vibrator 8
The vibration voltage of the ultrasonic oscillator is applied to the head, and the tip of the head section 3 undergoes bending deformation to ultrasonically vibrate. This allows
Ultrasonic vibration waves act on the skin surface, peeling off the old epidermis and lifting waste, the stratum corneum, or oil, dirt, and makeup residue on 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 5 slowly rotates at a speed of about 60 rpm and alternately rotates forward or backward. When the geared motor 5 rotates, the dirt, such as waste products, having the tip of the head portion 3 floating on the skin surface is washed and removed together with the cleansing cream. At the same time, it stretches the skin to relieve muscle tension, removes spots, wrinkles, and lumps, and opens pores to enhance the ultrasonic cleaning action. Further, the tip of the head portion 3 is stirred while pressing the cleansing cream on the skin surface, and the air mixed in the cleansing cream is pushed out to bring the tip of the head portion 3 into close contact with the skin surface, thereby increasing the ultrasonic wave propagation efficiency.

[0015]

As described above, the rotating probe of the ultrasonic cosmetic device according to the present invention rotates the head and rubs the skin surface. Therefore, according to the present invention, since the head rotates, the treatment can be felt and the interest can be maintained. Further, since the head rubs against the skin, the cream penetrates the skin, and dirt and the like floating on the surface of the skin are removed together with the cream. Thereby, the beautiful skin effect and the cleaning effect of the ultrasonic wave can be further enhanced.
