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 vibrational wave acts on the skin, it disinfects the skin surface layer, exfoliates waste and stratum corneum, and removes acne, oil from pores, dirt, and makeup residue. Cleanse, revitalize tissue by promoting blood circulation of the skin surface,
It has a beautiful skin effect that relieves muscle tension and removes spots, wrinkles, and lumps.

[0003] The temperature of the probe head of the ultrasonic cosmetic device is approximately the same as the temperature of the skin during treatment, but it is not comfortable to cool the skin when it is cold in winter. On the other hand, when the maximum temperature of the head is set to about 40 ° C., the ultrasonic vibration is combined with the heating effect of the head to promote blood circulation in the surface layer of the skin, activate the tissue, and further enhance the ultrasonic massage effect of relaxing muscle tension. Can be enhanced.

[0004] Further, since the probe head of the ultrasonic cosmetic device is heated with the passage of time due to the heating action of the ultrasonic wave, if it is used in contact with the skin surface for a long time, it may overheat and burn. For this reason, the probe of the ultrasonic cosmetic device could not be used continuously for a long time.

Accordingly, an object of the present invention is to provide a comfortable and effective skin treatment by properly adjusting the temperature of the probe head of the ultrasonic cosmetic device.

[0006]

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

[0007] More specifically, in 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, an air blowing means for blowing air, an air hole for discharging the blown air, and a head. Heating means for heating the head, temperature setting means for setting the temperature of the head, and temperature detecting means for detecting the temperature of the head, and adjusting the temperature of the head so that the detected temperature of the head becomes equal to the set temperature. It is a temperature control probe characterized by performing.

The vibrating body 12 is fitted with a ring-shaped concave portion a provided at the base portion and a ring-shaped convex portion b provided at the tip of the case 11. The case 11 is formed of a flexible elastic material, and the vibrating body 12 is released from the case 11 by using the convex portion b at the tip as a cushion so that the vibration of the vibrating body 12 is not restricted. Further, air holes H1 and H2 are formed in the vicinity of the convex portion b of the case 11 to discharge the air therein.

The vibrating body 12 is formed 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.

An ultrasonic vibrator 14 made of piezoelectric ceramics is fixed to the inside of the distal end surface of the vibrating body 12, and a thermistor 15 is attached near the vibrator.

The cooling air tube 31 and the heating air tube 31 ′ have the outlets at the distal ends thereof viewed from behind the ultrasonic vibrator 14, are focused on the cable 3, and are connected at the proximal ends to the compressor 21.

FIG. 3 shows a pipe connection diagram of the compressor 21. The pipe connection is made by connecting a straight pipe 31a to the intake port 21a.
And the base end of the branch pipe 31b is connected to the exhaust port 21b. Then, one end on the tip side of the branch pipe 31b is connected to the on-off valve V

The piping connection is configured as described above. When blowing out the cooling air tube 31, the on-off valve V1 is opened and V2 is closed. Conversely, the heating air tube 3
When blowing 1 ', the on-off valve V1 is closed and V2 is opened.

The temperature control probe embodying the present invention has the above-described configuration.
By operating the operation panel P, setting of the treatment time, setting of the output power and output frequency of the ultrasonic wave, setting of the head temperature, and the like are performed. Then, a gel or cream is applied to the treatment site or the tip of the vibrator 12. next,
The tip of the vibrating body 12 is lightly pressed at right angles to the skin surface, and the push switch 13 is turned on to move the probe along the skin surface so as to slowly draw a circle.

When the push switch 13 is turned on, the vibration voltage of the ultrasonic oscillator 22 is applied to the ultrasonic vibrator 14,
The vibrating body 12 bends and vibrates ultrasonically. As a result, the ultrasonic vibration wave acts to hit the skin surface, peeling off the old epidermis, waste matter, stratum corneum, or oil in pores,
Makes dirt, makeup residue, etc. stand out. 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 compressor 21 operates to operate the cooling air tube 31 or the heating air tube 31 '.
Air is blown out from the tip of the ultrasonic vibrator 1

The control circuit 23 detects the head temperature from the change in the resistance of the thermistor 15, and switches the on-off valves V1 and V2 to blow air from the cooling air tube 31 if the detected temperature is higher than the set temperature. , Lower the head temperature. Conversely, if the detected temperature is lower than the set temperature, the on-off valves V1 and V2 are switched to switch the heating air tube 3 on.
Air is blown out from 1 'to raise the head temperature. This keeps the head temperature at the set temperature.

[0025]

As described above, the temperature control probe of the present invention controls the temperature of the head so that the detected temperature of the head becomes equal to the set temperature. Therefore, according to the present invention, since the head temperature does not become too cold or too hot, a comfortable treatment can be performed. In addition, by appropriately increasing the head temperature, the heating effect of the head is added to the ultrasonic vibration, so that the ultrasonic massage effect can be further enhanced. Further, since the head is not overheated, it can be used for a long time, and sufficient energy of the vibration wave is applied to the skin to further enhance the effect of the beautiful skin treatment.
