The present invention relates to an ultrasonic beauty device in which ultrasonic waves and vacuum applied to the skin are controlled based on the skin condition for each facial region, and a skin condition management system including the same.

Ultrasonic beauty devices can obtain various cosmetic effects by delivering ultrasonic vibrations to the skin.

First, it is possible to increase the elasticity of the skin and reduce wrinkles through the transdermal injection of various cosmetics using ultrasound. In addition, it is possible to generate heat and mechanical energy by generating microscopic vibrations between human tissues and skin cells, thereby accelerating the metabolism of the skin. In addition, by activating fibroblasts in the dermis, it is possible to promote the synthesis of collagen and elastin to unfold wrinkles.

However, the existing ultrasonic beauty device transmits ultrasonic waves having the same frequency, amplitude, and duration over the entire face regardless of the facial region, so that proper treatment is not performed according to the skin condition for different facial regions.

A suction unit 30 for transferring vacuum pressure to the skin is formed on the outer surface of the head unit 20 facing the skin, and a piezoelectric element 42 is disposed inside the head unit 20 .

Referring to FIGS. 1 and 3 , the piezoelectric element 42 has a donut shape in which the center is drilled so as to be connected to the first communication hole 21 in the center. Ultrasound generated by the donut-shaped piezoelectric element 42 is transmitted to the skin through the inner and outer surfaces of the head 20 .

<Suction unit 30)>

1 and 2 , the suction unit 30 according to an embodiment of the present invention is formed on the outer surface of the head unit 20 . Here, the outer surface means the surface facing the skin.

The suction unit 30 includes a vacuum pressure transmission unit 31 and a skin contact unit 32 .

The vacuum pressure transmitting unit 31 has a cylindrical shape and a second communication hole 31 connected to the first communication hole 21 is formed in the center. The second communication hole 31 may be connected to the first communication hole 21 to receive the vacuum pressure generated by the vacuum pump 51 .

One end of the skin contact unit 32 is connected to the vacuum pressure transmitting unit 31 , and the other end is in contact with the skin.

One end of the skin contact part 32 is connected to the second communication hole 31 to transmit vacuum pressure from the second communication hole 31 . In addition, the other end of the skin contact part 32 may apply the vacuum pressure transmitted from the second communication hole 31 to the skin, thereby sucking waste products or residual cosmetics from the skin.

The skin contact portion 32 may have a shape of an octopus sucker so that the vacuum pressure transmitted to the skin in the shape of an octopus sucker is dispersed.

Referring to FIG. 4 , the existing cosmetic device capable of vacuum suction has a curved skin-contacting surface inward, so the vacuum pressure is concentrated, and excessive vacuum is applied to the skin, causing the skin to swell red and easy to move the cosmetic device. there was no

On the other hand, referring to FIG. 5 , the skin-contacting part 32 of the present invention may have a wider cross-sectional area as it approaches the skin.

The vacuum pressure delivered to the skin can be dispersed by spreading outward at an angle. Preferably, the diverging angle in the outward direction may be 35 to 50 degrees, preferably 45 degrees.

Since the skin contact part 32 is in the form of an octopus sucker bent outward at a predetermined angle, the vacuum pressure is dispersed, and when the user holds the main body of the ultrasonic beauty device 100 and the vacuum pressure is applied to the skin along with the ultrasonic waves, the skin It has the advantage of being able to move easily along the curves of the face while reducing the pain as no excessive vacuum is applied to the skin, preventing the skin from reddening and swelling.

<Ultrasonic transmission>

The ultrasonic oscillator 41 according to an embodiment of the present invention generates an ultrasonic signal including the frequency, amplitude, and duration of the ultrasonic wave, and transmits the generated ultrasonic signal to the piezoelectric element 42 .

Referring to FIG. 3 , the piezoelectric element 42 is a single (one) piezoelectric element and has a donut shape with an empty center. The piezoelectric element 42 generates low-frequency ultrasonic waves in a band of 1 to 7 Hz.

Referring to FIG. 1 , as the ultrasonic waves generated from the donut-shaped piezoelectric element 42 go deeper into the skin, the wavelengths overlap each other and the intensity of the ultrasonic waves becomes stronger. However, instead of focusing ultrasonic waves in a narrow range (focus range) like the existing focused ultrasonic waves, constructive interference is generated by the superposition of waves and the ultrasonic waves are evenly irradiated over a wide range as they go down to the depth of the skin. Even if it goes deep into the skin due to interference, the intensity of the ultrasound is not weakened to achieve a predetermined cosmetic effect.

Ultrasound generated by the interference phenomenon is weaker than the existing focused ultrasound, so it takes a longer time to apply the ultrasound to the skin, thereby maximizing the immune effect of the skin cells themselves, removing the root cause of wrinkles and blemishes. There is an advantage in that the cosmetic effect is longer than that of the existing ultrasonic beauty device.

Preferably, the duration of the ultrasonic wave generated by the piezoelectric element 42 of the present invention may be 30 to 90 seconds in a state in which the head unit 20 is stopped.

In order to transfer the vacuum pressure generated by the vacuum pump 51 to the head part 20 , a vacuum connection part 52 connecting between the vacuum pump 51 and the filter 53 may be further included.

The vacuum pressure generated by the vacuum pump 51 is transferred to the skin through the first communication hole 21 and the second communication hole 22 sequentially through the filter 53 through the vacuum connection part 52 .

The vacuum pressure delivered to the skin may suck wastes from pores of the skin, or suck a cosmetic applied to the skin and deliver it toward the filter 53 .

The ultrasonic sensor 62 may be installed on the outer surface of the head unit 20 as described above, but the thickness of the skin and the skin are measured by the ultrasonic waves sensed by the piezoelectric element 42 without using a separate ultrasonic sensor 62 . It is also possible to sense the amplitude of The difference in skin amplitude means wrinkles. If the difference in skin amplitude in the same facial region in the ultrasonic sensor 62 is significant, it means that there are wrinkles.

The optical sensor 63 of the present invention may sense skin color. The optical sensor 63 may be used to obtain information related to blemishes and skin color of the user of the ultrasonic beauty device 100 .

The dielectric constant sensor 64 of the present invention may sense the amount of moisture in the skin of the user of the ultrasonic beauty device 100 .

The control signal generator 75 generates a first control signal for controlling the ultrasonic oscillator 41 so that the piezoelectric element generates ultrasonic waves having the determined frequency, amplitude, and duration of the ultrasonic waves, and sends the generated ultrasonic waves to the ultrasonic oscillator 41 . can transmit

The first control signal is transmitted to the ultrasonic oscillator 41 to control the signal transmitted from the ultrasonic oscillator 41 to the piezoelectric element 42 to control the frequency, amplitude, and duration of the ultrasonic waves generated by the piezoelectric element 42 . can do.

For example, when information is received from the skin condition determination unit 74 that the facial region is around the eyes and that there are wrinkles, the data storage unit 72 indicates that the facial region is around the eyes and ultrasonic waves generated by the piezoelectric element 42 .
