Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a beauty device using ultrasonic waves, particularly an ultrasonic device with variable contact temperature that is effectively used for slimming, removing wrinkles, and preventing stains and freckles. It relates to a sonic beauty device.

[Conventional technology]

Conventionally, various methods have been proposed for beauty treatments, particularly for slimming beauty treatments. For example, eating less, aerobic exercise, etc. In any case, these methods are intended not to increase fat components contained in body tissues, such as cellulite, which causes obesity. A frugal diet essentially does not provide the nutrients that turn into fat.

In addition, moderate aerobic exercise consumes fat,
It reduces the amount of fat accumulated. In addition, to remove wrinkles, age spots, freckles, etc., beauty serums or creams are applied to the skin, and pine surge is applied to the skin to promote the function of the body's cells.

In the case of slimming, methods have also been proposed to improve the efficiency of fat circulation and prevent it from accumulating in the body. This type of method involves the application of pine surge or forced mechanical vibration to the muscles to artificially promote the function of the body's circulatory system, particularly blood vessels and lymphatic vessels, of cellular tissues. In that case, it is also effective to use other slimming methods in conjunction with dieting and moderate aerobic exercise, but slimming serums, creams, serums, etc. that strengthen the activity of biological organs are also used. . Applying pine surge or mechanical vibration can place excessive strain on muscles, and this strain may remain behind, resulting in physical fatigue, skin irritation, and the like.

As a method different from these beauty treatments, Japanese Patent Application No. 1-2
No. 62239 proposes an ultrasonic beauty device that applies ultrasonic waves directly to the area of the skin to be treated to reduce fat content by activating living tissues and increasing temperature.

[Problem of the Invention] An object of the present invention is to further develop this device and provide a more efficient ultrasonic beauty device.

[Means to solve problems]

The above problem has been solved by the present invention, which comprises a probe that can be held in hand for beauty treatment, and a power supply main body that controls the probe to perform a predetermined beauty treatment, and the probe has a contact plate that contacts the skin on the front surface. , a heat conversion element and an ultrasonic vibrator closely attached in parallel behind the contact plate, a heat sink placed heavily behind the heat conversion element, and a fan that air-cools a part of the heat sink, The power supply main body is an ultrasonic beauty device that controls the heat conversion element, the ultrasonic vibrator, and the fan according to a predetermined sequence inputted from a setting input section, respectively.

Further advantageous developments according to the invention are described in the dependent claims.

[For production]

The ultrasonic beauty device with the above configuration applies moderate ultrasonic vibrations to the muscles of the body, and if necessary, increases the temperature of the skin to be treated, causing muscle contraction, blood vessels, and lymph nodes. It strengthens the activity of the ducts, allows the main ingredients of beauty serums, especially slimming serums or beauty creams, to penetrate more deeply into the body, and also tightens the muscles and activates the metabolism of living tissues due to the cooling effect that is applied immediately after applying ultrasound. This further enhances the circulation of tissue fluids.

〔Example〕

This invention will be explained in more detail below based on the drawings.

FIG. 1 schematically shows a cross-sectional view of a probe 20 for an ultrasonic beauty device according to the present invention. This probe 20 can be easily handled with one hand, and the main body is preferably made of a cylindrical front cover 8 made of synthetic resin, which is coaxially connected to the cover 8, and is made of a hollow light metal material used for heat dissipation. It consists of a heat sink 9 made of aluminum or its alloy and a grip 12 also made of a lightweight material, preferably synthetic resin. Air introduced from the outside of the main body into the hollow space 17 inside the heat sink 9 is discharged to the outside by a blower 10 installed at the rear of the main body, and is transmitted to the heat sink 6, thereby eliminating the accumulated heat. Although the details of the blower 10 are not shown in the figure, it is a fan driven by a conventional electric motor, and is installed in the outer casing 11 to operate the thermal element 2 to heat or cool the contact plate 1. It is used to maintain the heat sink 9 at room temperature. In other words, the blower 10 causes the hollow space 1 to
The air introduced into 7 takes away heat from the heat sink 9,
It is discharged via the ventilation hole 18 at the rear of the probe body.

The front surface of the probe body is equipped with an ultrasonic generation section and a cooling section, which form the basis of this invention. That is, the main part of the ultrasonic generating section is the ultrasonic diaphragm 13, and this ultrasonic diaphragm 13 is energized from behind over the entire surface of the contact plate 1 by means of a pressing spring pin 4 and a spring 5 fixed to the transducer substrate 6. They are pressed together to make them stick together. The ultrasonic diaphragm 13 is a piezoelectric element that normally applies an excitation voltage to generate strain and induce ultrasonic vibration, and is made of, for example, halo titanate, titanate, or lead zirconate porcelain. In actual beauty treatment, the skin to be treated, i.e. the wrinkled or fatty buttocks, abdomen, waist, shoulders, neck,
The contact plate 1 is pressed against the face or the like, and ultrasonic vibrations are applied at a desired intensity and for a desired period of time. Advantageously, the contact plate 1 is made of a light metal, preferably aluminum or an alloy thereof, which is excellent in terms of sound wave transmission and at the same time heat conduction.

On the outer periphery of the ultrasonic diaphragm 13, a heat conversion element 2 is arranged between the contact plate 1 and the heat sink 90.

Contact between the two is achieved by tightening screws cut between the heat sink 9 and the front cover 8. Furthermore, as shown in FIG. 1, an O-ring 7 is inserted between the contact plate 1 and the front cover 80.
If it is hermetically sealed, the serum applied to the skin,
This is advantageous in preventing steam and moisture generated from the cream from entering the probe body, particularly penetrating the vibrator 3 and the heat exchange element 2, and causing deterioration or damage to these elements.

The heat exchange element 2 is used to cool the treated skin after applying ultrasound to tighten the skin tissue and increase the metabolism of the living body. It is usually advantageous to construct this element as a Hertier element. If a direct current is passed through this element, the temperature on one side will rise and the temperature on the other side will relatively drop, and if the direction of the current is reversed, the above relationship will be reversed. That is, when the direction of the current is reversed, the temperature on one surface decreases and the temperature on the other surface increases. If the other side is constantly air-cooled with a blower 10 as shown in Fig. 1 and kept at about room temperature, the other side can be made hotter or colder than the skin temperature. It is advantageous to maintain the temperature at a high temperature during the application of the ultrasound and at a low temperature after the application of the ultrasound.

The frequency of ultrasound used for beauty treatment is mainly 1 to 3.
It is set to 4 MHz. The harmonic wave is applied using a switch (not shown) provided on the grip 12 of the probe body 20.
Alternatively, this can be done using a foot switch installed outside the probe body 20, for example. The connection between the probe body and the power source for applied voltage is through conductive wires L1L2. to each element. L
3 (only partially shown).

FIG. 2 is a schematic diagram showing the structure of a power supply main body 30, which is an electric drive unit of the ultrasonic beauty device according to the present invention. A desired voltage (AC or DC1 or such voltage) is formed from the input IN to the power supply main body 30 in the power distribution unit 32 and is supplied to each predetermined circuit. blower 10 via
is supplied to

The beauty treatment settings, such as the order of ultrasound application and its period, are manually set (using keys, knobs, etc.) in the setting input section 36. Depending on the settings, the sequence control unit 3
5, the high frequency excitation circuit 33 and the thermal conversion current drive circuit 34 are controlled.

Typical modes in which the ultrasonic beauty device according to the present invention is used are illustrated below.

Similarly, one of the five steps for 5 to 10 minutes. Press one of the application time selection keys to apply Choose between.

Whether or not to raise the temperature when applying ultrasound, The changeover switch of the setting input section 36 and select.

Ultrasonic application starts with the start switch Press S to start.

ultrasound application of rear The setting input section 36 generates heat after applying ultrasonic waves. The operating time of element 2 in cooling mode is 1 Choose one of the three levels.

Immediately after applying ultrasound, the heating element 2 cooling mode is automatically started, Or you can manually start the cooling Depends on the mode selection key settings.

The above operation modes are illustrative and are not limited to this method. Selection of these modes is determined according to the designer's design philosophy.

Although various shapes and sizes can be assumed for the vibration transmission plate 13, it is effective to set it to be circular and have a diameter of about 40 mtrlφ, for example.

Rather than using the beauty device alone, if a beauty serum, especially a beauty serum containing caffeine that decomposes and melts cellulite, etc., which is fat, is applied to a desired area of the skin in advance, ultrasonic waves can be applied. Penetration is more effective with the help of

Of course, it is desirable to use this beauty device in a state where the cells are more activated, and it is even more effective when used after bathing, sauna, or steam bath.

〔Effect of the invention〕

A significant advantage of the ultrasonic device according to the present invention is that by applying ultrasonic waves to a desired skin region, it improves the circulation of tissue fluids, especially lymph and blood, while minimizing the stress on muscles. At the same time, it is possible to promote the penetration of the shell-shaped beauty cream or serum applied when applying the ultrasound. Therefore, compared to conventional manual pine surgery, the cosmetic agent can penetrate deeper into the skin more quickly and more effectively. In addition, by raising the temperature of the contact plate when applying ultrasound and decreasing the temperature of the contact plate after applying ultrasound, it is possible to further increase the metabolism of living tissue and tissue fluid, remove unnecessary fat, tighten muscles,
Effectively prevents sagging and wrinkles.
