Freezing-point laser hair removal instrument and working process thereof

Abstract

The invention relates to the technical field of skin beauty medical device, and discloses a freezing-point laser hair removal instrument. The freezing-point laser hair removal instrument comprises a main machine and an operating handle, wherein the main machine comprises a laser generation unit and a control unit, the operating handle is connected with the main machine, the operating handle comprises a key, a treatment head and a lamp tube, the laser generation unit is used for providing laser to the lamp tube, a color sensor and a light source are also installed in the operating handle, the lamp tube, the color sensor and the light source are arranged on the end part of the treatment head, the color sensor is electrically connected with the control unit, the color sensor is used for sensing the light, reflected by the human skin, of the light source, and when the color value of the color sensor falls in a preset range, the control unit controls the lamp tube to transmit the laser. The invention also discloses a working process of the freezing-point laser hair removal instrument. The control unit controls the lamp tube to automatically transmit the laser by judging the skin of the human body through the color sensor, and when the control unit judges that the freezing-point laser hair removal instrument leaves the skin of the human body for a period of time exceeding the predetermined time, the freezing-point laser hair removal instrument is automatically powered off.

Description

technical field [0001] The invention relates to the technical field of skin cosmetic medical devices, in particular to a freezing point laser hair removal instrument and its working process. Background technique [0002] Freezing point hair removal relies on the principle of selective photothermal action. The freezing point hair removal device uses laser to generate high heat in the hair follicles, thereby destroying the structure of the hair follicles and achieving the purpose of hair removal. Freezing point painless hair removal instrument with contact cooling head, which can limit the heat to damage the hair follicles, while allowing the heat to diffuse from the epidermis, in these cases, the skin does not reach the damage threshold and is protected from heat damage, so it will not be felt pain. [0003] The existing freezing point hair removal instrument includes a host and an operating handle, both of which realize the transmission of electricity and light through cabl...

Problems solved by technology

In this way of working, because the staff cannot accurately control the distance between the lamp tube of the operating handle and the human skin, the lamp tube is still in working condition before the operating handle approaches the skin and after leaving the skin, which not only consumes energy but also shortens the working time of the hair removal device. increase and reduce lifespan, in addition, it will also cause damage to human skin
