Description

Radio frequency beauty instrument handle capable of accurately measuring temperature

Technical Field

The invention relates to the field of beauty equipment, in particular to a radio frequency beauty instrument handle capable of accurately measuring temperature.

Background

With the rapid development of the beauty industry, the variety of beauty instruments is also gradually diversified. The existing radio frequency beauty instrument is provided with a beauty instrument handle, when the beauty instrument handle can emit radio frequency waves, the radio frequency waves can directly penetrate through skin to reach dermis when acting on human skin, and skin dermis tissues generate a thermal effect by utilizing the impedance effect of the skin, so that collagen tissues and fat cells are heated, collagen tightening is promoted, collagen regeneration is stimulated, and the effect of repairing skin relaxation and aging is finally realized. During the cosmetic process, the skin is easily damaged due to the excessive temperature at the skin, so it is generally necessary to provide a temperature sensor on the handle of the cosmetic instrument to detect the temperature at the skin during the cosmetic process.

See patent document CN211611335U, which discloses a radio frequency beauty treatment head, the bottom surface of the treatment head is used for being attached to the skin of a human body, and a blind hole for loading a temperature sensor is formed in the center. The bottom of the blind hole is accommodated with a temperature sensor which is fixed by heat conduction silica gel filled in the blind hole and detects the temperature of the bottom surface of the treatment head.

See also patent document CN213283317U, which discloses a radio frequency temperature detection handle provided with a downward facing massage head, the bottom surface of which is intended to lie against and massage the skin of the human body. The middle part of the massage head is provided with a temperature measuring head, the temperature measuring head is propped against the screw thread fixing column, so that the temperature measuring head is arranged in the massage head, and the temperature measuring head after being arranged in place penetrates out of the bottom surface of the massage head and is approximately flush with the bottom surface of the massage head. When the massage head is stuck to the skin of a human body with the bottom surface and massages the skin, the temperature measuring head is stuck to the skin of the human body and can directly measure the temperature of the skin.

However, the positions of the temperature sensors of the two handles are not adjustable after the temperature sensors are installed in place, the temperature sensors are easy to be outwards protruded or inwards contracted due to thermal expansion, cold contraction and the like after the handles are used for many times, the outwards protruded temperature sensors can excessively support the skin of a human body, discomfort of the skin can be caused when the massage head moves, and gaps are reserved between the inwards contracted temperature sensors and the skin of the human body, so that the temperature measurement accuracy is affected.
