Description

Ultrasonic beauty device {Skin care device using ultrasonic wave}

The present invention relates to an ultrasonic beauty device in which ultrasonic waves and vacuum applied to the skin are controlled based on skin conditions for each facial region.

Ultrasonic beauty devices deliver ultrasonic vibrations to the skin to obtain various cosmetic effects.

First, it is possible to increase elasticity of the skin and reduce wrinkles through transdermal injection of various cosmetics using ultrasonic waves. In addition, by causing fine vibrations between human tissue and skin cells to generate heat and mechanical energy, metabolism of the skin can be promoted. In addition, by activating fibroblasts in the dermis to promote the synthesis of collagen and elastin, wrinkles can be unfolded.

However, existing ultrasonic beauty devices have a disadvantage in that they do not perform appropriate procedures according to the skin conditions of different facial regions by transmitting ultrasonic waves having the same frequency, amplitude, and duration over the entire face regardless of the facial region.

In addition, the conventional ultrasonic beauty device concentrates ultrasonic waves to apply strong ultrasonic waves to the skin, and intensively irradiates high-intensity ultrasonic waves to a narrow area of the skin to remove unnecessary tissue. This ultrasound focusing method has the disadvantage of destroying normal cells or tissues, having a temporary skin beauty effect, and not being able to remove more fundamental causes.

Referring to FIGS. 1 and 3 , the piezoelectric element 42 has a donut shape with an open center so as to be connected to a first communication hole (not shown) in the center. Ultrasonic waves generated from the donut-shaped piezoelectric element 42 pass through the inner and outer surfaces of the head part 20 and are transmitted to the skin.

<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 exterior means the side facing the skin.

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

The vacuum pressure delivery unit 31 has a cylindrical shape, and a second communication hole (not shown) connected to a first communication hole (not shown) is formed in the center. The second communication hole (not shown) may be connected to the first communication hole (not shown) to receive vacuum pressure generated by the vacuum pump 51 .

However, instead of being focused and strengthened in a narrow range (focus range) like conventional focusing ultrasound, constructive interference is generated by overlapping waves, and the ultrasound is evenly irradiated over a wide range as it goes deeper into the skin, and the reinforcement The intensity of the ultrasonic wave is not weakened so as to achieve a predetermined cosmetic effect even when the ultrasonic wave is transmitted to the deep skin due to interference.

The ultrasound generated by this interference phenomenon is weaker than the conventional focused ultrasound, so it takes longer to apply the ultrasound to the skin, maximizing the immune effect of the skin cells themselves, eliminating the root cause of wrinkles and melasma. It has the advantage that the beauty effect is longer than the existing ultrasonic beauty device.

Although the ultrasonic sensor 62 may be installed on the outer surface of the head part 20 as described above, the skin thickness and skin thickness are measured by ultrasonic waves sensed by the piezoelectric element 42 without using a separate ultrasonic sensor 62. The amplitude of may be sensed. The difference in amplitude of the skin means wrinkles, and if the difference in amplitude of the skin in the same face area in the ultrasonic sensor 62 is severe, it means that there are wrinkles.

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

For example, when information is received from the skin condition determining unit 74 that the face area is around the eyes and wrinkles are received, the data storage unit 72 shows that the area around the eyes is located around the eyes and the ultrasonic wave generated by the piezoelectric element 42 A first control signal for controlling the ultrasonic oscillator 41 may be generated and transmitted to the ultrasonic oscillator 41 so as to have an ultrasonic frequency band, amplitude, and duration capable of preventing or removing wrinkles.
