Description

Technical Field

[0001] The present disclosure relates to a handpiece used for skin treatment and skin beauty purposes and a charging stand system including the same.

Background Art

[0002] As humans age, facial muscles lose elasticity, resulting in wrinkles or sagging skin. With the development of the beauty industry, beauty devices related to skin care have been developed to prevent visible wrinkles and sagging of the skin (especially the face).

[0003] Beauty devices have been used as devices that can not only increase the production of collagen and elastic fibers by electrical stimulation, regenerate skin cells, but also make the skin healthy and elastic through cell regeneration and increased blood flow to perform skin protection and skin care.

[0004] Conventional handpieces include an ultrasonic oscillation unit that effectively transmits the nutritional components of ultrasonic gel applied to the skin surface by ultrasonic vibration to subcutaneous tissue, generates ultrasonic waves by including a piezoelectric element in an ultrasonic probe, and a skin contact part. A spherical rotating body is rotatably coupled, and an electrical stimulation generating part is formed inside the handpiece to transmit electrical stimulation to the rotating body (energy generating part).

[0005] The above information can be provided as background art (relevant art) for helping the understanding of the present disclosure. No claim or determination is made as to whether any of the above contents can be applied as prior art in relation to the present disclosure.

Summary of the Invention

[0007] However, when performing skin massage using a handpiece, there is a risk that the axis of rotation may shift as the rotating body rolls, and if the axis of rotation shifts, especially at night, there is a risk that the transmission of low-frequency current may be interrupted or the energy intensity may change.
