DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic oscillator, in which the frequency of ultrasonic waves is concentrated at a central portion, which may impair safety, that a connecting line generates noise, and a probe which comes into contact with a human body. The present invention relates to a means for preventing a possibility of electric shock in a metal tip.

2. Description of the Related Art An ultrasonic cosmetic device is an instrument for eliminating wrinkles and spots on the skin of the face, removing subcutaneous fat from the body, and correcting obesity. Conventionally, two or three types are commercially available. One of them has a fixed high-frequency current generator, and the other has a probe that moves on a human body surface while oscillating ultrasonic waves. Therefore, it is composed of a high-frequency current connecting line connecting them. A metal flat plate that oscillates ultrasonic waves is attached to the probe head. However, such a structure has the following major problems. a. Since a current in a radio band of 1 to 3 MHz flows as a drive current in a connection line between the ultrasonic transducer of the probe and the high-frequency power supply, noise is easily generated from the connection line. In particular, in the conventional Colpitts type oscillation circuit (FIG. 8), the connection line cannot be grounded, so that it becomes an antenna and generates noise radio waves. b. The ultrasonic oscillation plate of the probe head facing the skin is not grounded, and there is a high-frequency potential difference of 50 to 80 V between the power supply for driving the vibrator and the oscillation plate. May flow. If a Colpitts type oscillation circuit is used as shown in FIG. 2 or a Hartley type oscillation circuit (FIG. 1) is employed, grounding is possible and safety is ensured. c. In the case of an extremely high frequency of 1 to 3 MHZ, the ultrasonic waves to be oscillated are shown in a polar coordinate diagram. As shown in FIG. It can penetrate to some extent and cause pain, and can be dangerous depending on the part of the body. As a conventional technique, there is a document that attaches a hollow box outside the ultrasonic oscillation plate at the tip of the probe and fills water to form a water layer in order to oscillate ultrasonic waves to a wide range of skin. However, the direction of travel of the ultrasound is not affected by the presence of water, as is also used in fish finder, and it is not possible to prevent the ultrasound from being concentrated in the center by this method.

[0003] An ultrasonic cosmetic device is very effective for cosmetics because it has a massage effect if the probe is pressed against the skin and moved. However, some conventional models prohibit pressing strongly against the skin or stagnating in one place, and this is considered to be a cautionary measure that the ultrasound contains a sharp beam. Commercially selling such a device is extremely dangerous.

[0004]

SUMMARY OF THE INVENTION In an ultrasonic cosmetic device for eliminating small wrinkles and spots on the face and correcting obesity of the body, ultrasonic waves generated in a high frequency region are concentrated in a sharp beam, and high frequency signals are generated. It is an object of the present invention to provide an ultrasonic cosmetic device that prevents noise from being generated from a cable connecting a device and a probe and prevents an ultrasonic oscillation plate at the tip of the probe from being grounded.

[0005]

The present invention employs the following means to achieve the above object. 1. In a cosmetic ultrasonic oscillator, the ultrasonic waves oscillated at the center are diffused so that the ultrasonic waves that are oscillated do not damage the skin or the tissue behind it. A high-frequency current having a lower frequency than that is applied and modulated. (Fig. 1)

[0006] 2. Since the high-frequency supply circuit and the vibrating section in the probe are connected by a high-frequency current connection line, this is a noise source. In the present invention, in order to eliminate the generation of noise, by incorporating a transducer basic high frequency oscillation circuit other than the above-mentioned modulation circuit in the handle of the probe, the connection line becomes only a DC power source to be driven and a so-called signal circuit. No noise is generated. (Fig. 2)

[0007] 3. In the ultrasonic cosmetic device, a structure for diffusing ultrasonic waves is added as follows. The oscillation plate has a concave lens shape. To this end, the oscillation plate itself is formed into a concave lens shape, or a metal or glass concave lens is bonded to the oscillation plate. As it is hard to slip on skin with concave lens, we cover with convex metal surface or plane,
Seal the liquid in the space between them. (Fig. 3) A metal or glass convex lens or flat plate is adhered to the oscillation plate, a triangular groove is cut in a star shape at the center, the groove surface is finished to a mirror surface, and ultrasonic waves concentrated at the center are refracted and reflected like light. Spread. (FIG. 4) The oscillating plate is formed into a spherical surface together with the vibrator, and ultrasonic waves are oscillated and diffused in a spherical shape. (Fig. 5) The oscillation plate is formed into a hemispherical body with metal or glass, the bottom plate is attached with a flat plate, and a gas or liquid is sealed inside.
A cylindrical foot is attached to the bottom surface of the bottom plate, and is fitted into a hole of a ring-shaped vibrator in which two annular electrodes are fitted on the inner and outer surfaces. (FIG. 6)

[0008] 4. In the present invention, the probe head is formed in a gooseneck shape, which makes it convenient to use it in contact with its own skin. (Fig. 5)

[0009]

[Function] Ultrasonic beauty equipment oscillates ultrasonic waves without contacting the probe with the skin of the face or body, so if the waves may contain dangerous ultrasonic waves, they must be avoided. Must. The amplitude of the ultrasonic wave decreases as the frequency increases, but the acceleration of the particles increases in proportion to the square of the frequency, and the danger increases. When the frequency increases, the directional front becomes narrower and concentrated as shown in FIG. Therefore, it is necessary to diffuse cosmetic ultrasound. The present invention diffuses the concentration of the ultrasonic wave at the center of the front surface and flattens the traveling surface as shown in FIG. 7B. The solid line is a polar coordinate diagram, the dotted line is a rectangular coordinate diagram, and the horizontal axis is the diameter of the oscillation plate.

[0010] 1. In order to cause the diffusion of ultrasonic waves by an electric circuit, it is sufficient to mix ultrasonic waves of a lower frequency.
Due to the mixing of the two frequencies, a wave component of a right angle component is generated in the rightward direction, and the ultrasonic wave is made to travel in the direction of diffusion. For example, by modulating a fundamental high-frequency power of 100 KHZ or more for ultrasonically vibrating the vibrator of the probe head with a lower high-frequency power of 20 to 100 KHz, a vibration wave concentrated in a beam shape is diffused, and a flat vibration is generated. Can make waves. (Fig. 1)

2. When connecting the power supply unit and the probe with a connection line in the ultrasonic cosmetic device, if the high-frequency generation circuit is a Colpitts-type oscillation circuit, the connection line cannot be grounded, causing radio noise or electric shock. There is a fear of. In this case, if the basic high frequency generating circuit for the vibrator excluding the modulation signal circuit is incorporated in the probe, the connecting line is only the modulation signal line that can be grounded to the drive DC line, and no noise is generated and no electric shock is caused. (Fig. 2)

3. Ultrasonic waves exhibit properties similar to light at 1 MHZ or higher, so the following is adopted as a structural method for diffusing the concentration of ultrasonic waves at the front center. The oscillation plate has a concave lens shape. For this purpose, the oscillation plate itself is formed into a concave lens shape, or a metal or glass concave lens is bonded to the oscillation plate. Ultrasonic waves are diffused by concave lenses, like light. As the adhesive, use a thin transparent material that does not contain a substance that interferes with the ultrasonic wave. (Fig. 3) A metal or glass convex lens or flat plate is adhered to the oscillation plate, and a triangular groove is cut into a star shape at the center, and the groove surface is finished like a mirror. The ultrasonic waves are refracted or reflected like light by the groove surface, and the ultrasonic waves concentrated at the center are scattered and diffused. (FIG. 4) The oscillation plate is bent into a spherical shape together with the vibrator, and the ultrasonic waves are diffused and emitted in all directions. (Fig. 5) An annular vibrator with a hemispherical oscillating plate, a bottom surface attached, a gas or liquid sealed in, a cylindrical foot fixed under the bottom surface, and an electrode ring fitted in the outer and inner peripheries. This is a structure in which the cylindrical foot is fitted in a hole. The high-frequency current gives a high-frequency voltage to the inner surface and the outer surface of the ring-shaped vibrator, so that the hemispherical oscillator oscillates ultrasonic waves mainly in a horizontal ring shape, and the amount of ultrasonic waves oscillated in front is small. (FIG. 6)

4. Conventionally, all the probes of the commercially available supersonic wave beauty device are made in a right cylindrical shape, but in the present invention, the probe head is formed in a gooseneck shape like a handset of a public telephone, and the probe head is brought into contact with its own skin. Make it convenient to use. (Fig. 5)

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 8 is an explanatory diagram in which a Colpitts-type high-frequency circuit is used for a probe of a conventional ultrasonic cosmetic apparatus. In this case, a long cable is connected between the capacitor Ca and the probe 1.
Even if a shield wire is used, the outer sheath wire 3 cannot be grounded, and noise will be generated from now on.

FIG. 1 is a circuit diagram in which a modulation signal circuit for diffusing an ultrasonic wave is incorporated in a Hartley type high frequency circuit of the ultrasonic cosmetic device. The main ultrasonic wave of the ultrasonic cosmetic device concentrates on the front in the traveling direction as the frequency is higher, which may be dangerous, so the main ultrasonic wave can be diffused by putting an ultrasonic wave with a lower frequency. . The modulation signal circuit 4 is a high-frequency circuit having a lower frequency than the fundamental oscillation high frequency. In FIG. 1, 10
Generates a high frequency of 0 KHZ or more. The frequency is adjusted to the resonance frequency of the vibrator 7 and the oscillation plate 8. Waveform input line 2
5 is supplied with a rectangular wave or a sine wave of 20 to 100 KHZ, amplified, and modulated by the modulation signal circuit 4. When one of the secondary windings 21 is grounded, the outer sheath 3 of the coaxial line is also grounded, and the pole 27 of the vibrator 7 and the metal oscillation plate 8 which is in direct contact with the skin are also grounded. Is safe.

FIG. 2 is an explanatory diagram in which a Colpitts-type high-frequency circuit is employed for the probe 1 of the ultrasonic cosmetic apparatus according to the present invention.
In this case, even if a Colpitts-type high-frequency circuit is used, except for the modulation circuit 4, the high-frequency circuit is entirely built in the probe 1, so that the connection line 6 is only a drive power supply DC line and no radio wave is generated. On the other hand, a lower high-frequency modulation circuit 4
Is added, noise is not generated if the connection line 6 of the drive power supply DC line is coaxial and grounded. In FIG. 2, components 34, 35, and 36 generate high-frequency vibrations in accordance with the resonance frequencies of the vibrator 7 and the oscillation plate 8, and the connection line 6 is coaxially connected to the power supply 31 and the modulation circuit 4. 33-36
Are housed in the handle portion of the probe 1 and the coaxial outer wire 3 of the connecting wire G is grounded on the power supply 31 side. Does not generate noise.

FIGS. 3, 4, 5, and 6 show a structural method for diffusing the ultrasonic waves oscillated by the ultrasonic cosmetic device from being concentrated on the front in the traveling direction. FIG. 3 shows that the inner surface of the oscillating plate 8 is conventionally flat and the outer surface is formed in a concave lens shape, or a concave lens 9 made of metal or glass is adhered to the outer surface of the oscillating plate 8 so that it is flat or spherical so as to slide well with the skin. And cover the space with the concave lens. Oscillator 8 and vibrator 7, cover 10, probe 1
A hard rubber packing 11 is inserted into each gap. Ultrasonic waves are diffused like light by concave lenses. In FIG. 4, a convex lens 12 of metal or transparent glass or a flat plate having a thickness of about the lens is adhered to the outer surface of the oscillation plate 8, and a star shape emitting a light beam as shown in a plan view B is formed at the center thereof by a triangular groove 13. Finish the cut groove surface like a mirror surface. Ultrasonic waves concentrated at the center are refracted or reflected like light by the star-shaped groove surface and diffused to the surroundings.

FIG. 5 shows that both the oscillation plate 8 and the vibrator 7 are spherically shaped.
4, the ultrasonic wave oscillates from the oscillation plate 8 and the vibrator 7 in a direction perpendicular to each part thereof, so that the front of the ultrasonic wave is naturally diffused. The probe 1 has conventionally used a straight cylindrical body, but in the present invention, the head portion is bent into a gooseneck shape so that the user can easily use the probe on his or her own body. In FIG. 6, the oscillating plate 8 is expanded outward in the shape of a hemisphere 15 and a bottom plate 16 is attached to enclose a gas or liquid in the hemispheric cavity. A cylindrical foot 17 is fixed below the bottom plate 16, and an annular high-frequency pole face 18 is firmly inserted into a hole of the annular vibrator 7 fitted on the outer circumference and the inner circumference, and the outer circumference of the cylindrical foot 17 is hard rubber packing 1.
1 and attached to the probe head 1. In this structure, the spherical oscillation plate 8 oscillates mainly in the annular direction, and the concentration of ultrasonic waves is completely prevented. The ultrasonic oscillator having such a structure is not limited to cosmetics, but is attached to the bottom of a container containing water or liquid to vibrate the water or liquid in the container, and is used for cleaning soaked small articles.

[0019]

The higher the frequency of the high-frequency current that generates the ultrasonic waves, the higher the frequency of the high-frequency currents, the more the ultrasonic waves concentrate in the center of the traveling direction, and if the pain is given to the beauty user or reaches deep tissue, the possibility of danger increases. However, cosmetic effects cannot be expected with low-frequency, high-frequency ultrasonic waves. Therefore, in the present invention, a high-frequency ultrasonic wave is used, but an ultrasonic wave concentrated at the center is diffused to create an absolutely safe beauty device while enhancing a cosmetic effect. This is expected to eliminate wrinkles and spots on the face, reduce the fat layer of the body and please many women, and reduce obesity and bring the gospel to those concerned about diabetes.
