Description

Laser handle that moults

Technical Field

The utility model relates to the technical field of laser unhairing, in particular to a laser unhairing handle.

Background

The laser dehairing technology is based on the selective absorption principle, and by reasonably adjusting the wavelength, energy and pulse width of laser, the laser can pass through the skin surface layer to reach the root hair follicle of the hair, and the light energy is absorbed and converted into heat energy which damages the hair follicle tissue, so that the hair loses the regeneration capability, and the peripheral tissue is not damaged, and the pain is slight. The laser dehairing effect can achieve the permanent dehairing effect because the heat absorption and necrosis process of the hair follicle is irreversible.

The utility model patent with the Chinese patent application number of 202120794521.4 discloses a freezing point type laser unhairing handle, which is characterized in that a built-in water cooling assembly is used for radiating heat of a conducting head and a laser, the radiating area is large, the heat generated by the loss of energy consumption of the laser can be taken away extremely efficiently, the stability of energy power is ensured, the risk of burning of the laser is avoided, meanwhile, the utilization efficiency of a refrigerating sheet group in the water cooling assembly is higher, the conducting head can be continuously at the freezing point temperature, the pain caused by slight burning of the skin of a user is relieved, and the comfort is improved. But it has the following disadvantages: the water cooling assembly is used for radiating heat of the conductive head and the laser, the radiating area is large, heat generated by energy loss and energy consumption of the laser can be taken away extremely efficiently, and the stability of energy power is ensured, so that the laser is in normal operation, and the number of times of hair light emission of an arm continuously removed by the normal operation laser is 300 to 500. When the laser is used for a long time, once the number of times of light emission exceeds, the laser is easy to damage, unstable light emission is caused, the output energy is easy to increase or decrease suddenly due to serious aging damage, medical accidents are caused, the risk of burning the laser is caused by the increase of the output energy, and the hair loss is not effective even the hair growth is stimulated due to the decrease of the output energy.

The utility model patent with the Chinese patent application number of 202220334538.6 discloses a light-emitting protection device for a laser unhairing handle, which aims to solve the problems that the existing 808nm laser unhairing handle in the market is small and exquisite, and the front end is integrated with devices such as skin detection and the like, so that potential safety hazards exist in the production test, conventional inspection and use of the existing equipment. But it has the following disadvantages: the disadvantage of the "ranging sensor module" such a light-emitting protection device is that the ranging sensor module is located directly under the handle gun head, and the ranging sensor module cannot accurately detect the distance from the light area to the skin because the skin of a person is not a plane.

In conclusion, the laser dehairing instrument is connected with the handle laser through a host power supply, and the wavelength, the energy and the pulse width of the laser are adjusted through program control, so that energy is emitted to locally dehairing human skin. The prior art mainly has the following two technical problems: firstly, as any component has service life, the number of times of light emission of the laser is limited, once the number of times of light emission exceeds the number of times of light emission of the laser is used for a long time, the laser is easy to damage, so that light emission is unstable, the output energy is easy to be increased or reduced suddenly due to serious aging and damage, the laser is burnt out and skin burns to cause medical accidents due to the increase of the output energy, and the unhairing is invalid even the hair growth is stimulated due to the reduction of the output energy; secondly, the distance measurement sensor module adopted by the existing laser depilating handle can not accurately detect the distance from the light area to the skin.
