In use, first, a special gel containing paraben or the like is applied to a face or a body part to which the probe is applied, and the probe is pressed against the gel to perform massage. By doing so, the ultrasonic vibration oscillated from the probe penetrates the stratum corneum and reaches the dermis deep in the skin, removes impurities from aging skin and pores, activates the skin, and can promote metabolism . This can rejuvenate the skin and remove excess fat from the body.

However, the oscillation frequency of the ultrasonic oscillation unit in the conventional ultrasonic cosmetic device generally has a band of 0.5 MHz to 4 MHz, and the frequency component is an ultrasonic oscillation by a sine wave or a rectangular wave, and is oscillated from the probe. The skin is continuously stimulated by ultrasonic vibration. The output level of the ultrasonic oscillation is set to be relatively high in order to enhance the use effect. When the output level is lowered, the use effect is reduced, so that the output level is not weakened. If the ultrasonic cosmetic device is continuously used under such conditions, not only users with weak skin but also general users may cause serious damage to skin cells on the skin surface and deep skin. was there. In addition, there is a problem in that discomfort is given even during use.

Embodiments and Examples of the Invention
Embodiments and examples of the present invention will be described with reference to the drawings. FIG. 1 is a circuit block diagram of an embodiment of the ultrasonic cosmetic device of the present invention, and FIG. 2 is an example of a modulated output waveform of the ultrasonic cosmetic device of the present invention.
[0010]
As shown in FIG. 1, the ultrasonic cosmetic device 1 of the present invention includes an ultrasonic oscillation unit 2 for generating an ultrasonic wave, a 1 / f fluctuation oscillation unit 3 for generating a 1 / f fluctuation wave, A modulating unit 4 for combining the ultrasonic wave and the 1 / f fluctuation wave to generate an amplitude modulated wave, an amplifying unit 5 for amplifying the output of the amplitude modulated wave, and converting an electric signal into a physical vibration It comprises an oscillator 7 for conversion, a power supply unit 8 for supplying power to each of the circuit blocks, and the like.
[0011]
The oscillation frequency in the ultrasonic oscillation unit 2 is a general band of 0.5 MHz to 4 MHz, and the oscillation waveform uses a sine wave, a rectangular wave, a digital pseudo sine wave, or the like. The setting of the oscillation frequency and the oscillation waveform in the actual ultrasonic cosmetic device 1 may be a fixed type arbitrarily set for each model of the ultrasonic cosmetic device 1 or a selection type having several patterns.
[0012]
The oscillation frequency of the 1 / f fluctuation oscillating unit 3 is in a band of 0.5 Hz to 4 Hz, and the oscillation waveform is a sine wave. The frequency of 0.5 Hz to 4 Hz is called a delta wave in a human brain wave, and is an unconscious frequency. The delta wave is a 1 / f fluctuation frequency which is considered to be effective for relaxing the mind and body and recovering from fatigue together with the alpha wave (7 to 14 Hz) and theta wave (4 to 7 Hz). The ultrasonic cosmetic device 1 of the present invention employs a delta wave having a high effect among the 1 / f fluctuation frequencies. Further, the frequency of the delta wave can be changed by the built-in volume 9 according to the user's preference.
[0013]
The modulating unit 4 combines the ultrasonic wave generated from the ultrasonic wave oscillating unit 2 with the 1 / f fluctuation wave generated from the 1 / f fluctuation oscillating unit 3 to generate an amplitude modulated wave shown in FIG. In the figure, it can be seen that the ultrasonic component 11 of 0.5 MHz to 4 MHz is amplitude-modulated by the 1 / f fluctuation component 12 of 0.5 Hz to 4 Hz. Here, assuming that the peak maximum value of the amplitude modulation is “a” and the peak minimum value is “b”, the modulation degree (%) can be expressed by the equation (ab) × 100 / (a + b). The degree of modulation can be varied from 0 to 100% by the built-in volume 10 according to the preference of the user. The frequency and the modulation of the delta wave may not be variable, but may be a fixed type arbitrarily set for each model of the ultrasonic cosmetic device 1.
[0014]
The amplifier 5 amplifies the amplitude-modulated wave to an output level at which the oscillator 7 connected to the external probe 6 or the built-in probe can be ultrasonically vibrated.
[0015]
The power supply section 8 supplies power to the ultrasonic oscillation section 2, the 1 / f fluctuation oscillation section 3, the modulation section 4, the amplification section 5 and the like, and a DC power supply in which an external AC power supply or DC power supply is stabilized. It is converted into a power supply. In the case of the portable ultrasonic cosmetic device 1, the power supply unit 8 may be a primary battery such as an alkaline dry battery or a secondary battery such as a rechargeable lithium ion battery.
[0016]
In the ultrasonic cosmetic device 1 of the present invention constituted by the above-described circuit blocks, the ultrasonic vibration generated from the oscillator 7 is amplitude-modulated by a 0.5 Hz to 4 Hz delta wave shown in FIG. It is a wave, and if the skin of the face and the body is massaged by the ultrasonic vibration by the modulated wave, unlike the case of the conventional continuous ultrasonic vibration, even if the output level is lowered, the use effect is equivalent without lowering In addition, a relaxing effect due to 1 / f fluctuation can be obtained. For this reason, not only general users but also users with weak skin do not damage the skin cells on the skin surface and the skin deep in the skin, do not give any discomfort during use, and furthermore, It is also effective for relaxation, fatigue recovery and slimming.

As described above, if the skin of the face or the body is massaged using the ultrasonic cosmetic device of the present invention, the use effect is reduced even if the output of the ultrasonic vibration is reduced from the conventional ultrasonic cosmetic device. Without any damage to the skin cells and skin cells deep in the skin, not to mention the general user, as well as the general user, without causing discomfort even during use Furthermore, the frequency component of the delta wave, which is a 1 / f fluctuation wave, can exert a tremendous effect of relaxing the mind and body and exerting effects on fatigue recovery and slimming.
