Background

In recent years, radio frequency technology has been widely used in medical and cosmetic fields. The working principle of the radiofrequency instrument is to utilize the thermal effect of current. Thermal effect of current: when current passes through the resistor, the current acts to consume electric energy, and heat is generated. It is known from Joule's law that the heat generated by the current passing through the conductor and the square of the current, the resistance value of the conductor itself and the time of passing the current are proportional to the current passing through the resistance wire in the handle, the electric energy is converted into heat energy, when the heat energy is effective in the dermis layer, the existing atrophic fibers are broken, and after cooling, new collagen is rearranged and regenerated, so that the blood circulation is promoted, the skin metabolism is enhanced, and wrinkles are improved.

In the related art, the desk type radio frequency instrument mainly comprises the following parts: host, treatment handle, power cord, etc. The desk type radio frequency instrument is inserted with a power line, under the condition of electrifying, the treatment handle is placed at a corresponding position, the switch is started, the treatment handle starts to work normally, the electrode head at the end part of the treatment handle generates heat, the electrode head is made of metal, and the electrode head contacts with the skin of a human body to transfer the heat to the dermis layer; when the treatment is carried out through the treatment handle, gel is often smeared on the skin of a user, and the effect of the smeared gel is used for enabling heat to be transferred more uniformly and fully on one hand and enabling the electrode head to run on the skin of the user more smoothly and more comfortably on the other hand.

According to the related technology, when the gel is smeared on the skin of a user, the gel is difficult to smear uniformly, partial gel accumulation at the skin position can occur, and when the electrode tip of the treatment handle is operated to massage the skin, the electrode tip enters the position where the gel is accumulated, at the moment, the electrode tip is close to a part of the skin to be wrapped by the gel, because the electrode tip is heated to generate heat, after the electrode tip is wrapped by the gel, the electrode tip transmits the heat to the gel, the electrode tip heats the gel, the temperature of the gel rises, bubbles are generated in the gel, the heated gel splashes after the explosion of the bubbles, and the splashed gel drops on the skin of the user, so that discomfort, pain and even scalding of the skin of the user are easily caused, and safety problems are caused.
