Description

Shell assembly and radio frequency beauty equipment

Technical Field

The present disclosure relates to the field of cosmetic instruments and devices, and in particular, to a housing assembly and a radio frequency cosmetic device.

Background

The radio frequency beauty instrument is an instrument for applying power radio frequency energy with specific waveform to human skin; in the beauty care process, the electrode acts on the skin of the human body to generate radio frequency current, so that the skin of the human body flows through the conduction current and the displacement current to form internal heating, and the effect of caring the skin is achieved.

The skin area acts as a load when the electrodes contact the skin, and the electrodes formed by the positive and negative electrodes provide a high frequency alternating electrical signal to the load, delivering radio frequency energy to the deep subcutaneous tissue. When the radio frequency current passes through the epidermis to reach the dermis and is blocked by the resistance of the cell tissues, the high frequency oscillation generates heat energy to denature collagen in the dermis so as to excite an in-vivo healing mechanism to enable the elastic fiber cells to generate new collagen.

In the related art, the shape of the electrode head shell of the radio frequency beauty instrument is in a complex curved surface structure, and the electrode assembly and the LED light source assembly are often arranged on the same side of the electrode head shell. With the technical development of the radio frequency beauty instrument, users have more expansion function demands on the radio frequency beauty instrument, however, when the expansion function component cannot be integrated with the electrode component and the LED light source component on the same side of the electrode head shell, the complex curved surface structure limits the electrode head shell to accommodate more expansion function components. Therefore, how to improve the diversity of the structural functions of the cosmetic instrument housing assembly is an important issue to be solved.
