Description

Ultrasonic skin beauty device {ULTRASONIC MASSAGER}

The present invention relates to an ultrasonic skin care device capable of adjusting the intensity according to the skin condition.

Ultrasound is a sound that vibrates so fast that humans cannot hear it. In engineering, it refers to a sound that vibrates more than 20,000 times per second. It has a strong shaking force, and these ultrasonic waves have the same properties of radio waves and light as well as the properties of sound. The above ultrasonic waves are used in various fields such as ultrasonic cleaners, ultrasonic humidifiers, fish detectors, ultrasonic welding, and ultrasonic tomography diagnosis. As it has the same therapeutic effect as massage, it is also applied to ultrasonic therapy devices used for the treatment of arthritis, rheumatism, back pain, post-traumatic pain, neuralgia, etc. as one of the medical physical therapy therapies. Therefore, an ultrasonic skin beauty device using this for beauty is being developed.

Ultrasonic skin beauty device is a high-speed massage that applies soft ultrasonic waves that are optimal for the skin to the skin, and the ultrasonic waves act on the skin surface or 4-5 cm below the skin, and apply instantaneous pressure fluctuations to blood vessels, cells, and lymphatic vessels. It acts as a cleansing action to remove impurities deep in the pores and at the same time activates the skin by accelerating the metabolism of the skin tissue by warming the deep part of the skin and accelerating the flow of blood or lymph. A ceramic ultrasonic vibrating element (vibration transducer) is directly attached to the probe head, and ultrasonic waves of a certain frequency are applied for a set period of time to output oscillation and convert it into vibration. .
