Problems solved by technology

The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus causing the hair to lose its ability to regenerate. Because the device is a relatively high-power device, it generates a large amount of heat. After a long period of continuous work, the temperature of the device will be too high and the device will work abnormally. It can even burn human tissue, causing irreversible and permanent damage
At present, the existing technology monitors the temperature on the surface of the hair removal head to judge whether the temperature exceeds the set value. When the temperature exceeds the set value, the protection circuit on the laser hair removal device stops the laser hair removal device from working, and it needs to wait for a long time to cool down. Such a working method very unfriendly

Embodiment 1

[0057] Taking one of the laser hair removal instruments as an example, the implementation process is as follows:

[0058] A. When the equipment is turned on, the temperature is about 25°C at room temperature;

[0059] B. After working for a certain period of time, the temperature rises to T2=42°C, which is relatively close to the preset threshold T=45°C;

[0060] C. The algorithm unit judges that the temperature is close to the threshold, and it is necessary to start an adjustment plan to cool down;

[0061] D. The control unit adjusts the light output speed to x1=50% of the default speed;

[0062] E. After maintaining for 20 minutes, the temperature drops T1=35°C, which is 36.5°C lower than the body temperature;

[0063] F. The algorithm unit judges that the adjustment range is too large, and the adjustment plan needs to be corrected, and an instruction is given to increase the light output speed;

[0064] G. The control unit adjusts the light output speed to the default x...

Abstract

The invention provides a control method of a laser hair removal instrument. The laser hair removal instrument is configured, and a temperature sensor is arranged on a skin contact surface of the laser hair removal instrument; the temperature sensor monitors a temperature value of the skin contact surface; a controller comprises an algorithm unit, and the temperature value is transmitted to the algorithm unit of the laser hair removal instrument; and according to the conclusion obtained by the algorithm unit, a control unit controls the light emitting speed and the light emitting energy, and the algorithm unit executes continuous work according to whether the temperature value is within a set range or not, if yes, the light emitting speed and the light emitting energy are adjusted, or the light emitting speed and the light emitting energy are adjusted at the same time. The control method of the laser hair removal instrument has the beneficial effects that the problems of use interruption and danger caused by too high temperature when the laser hair removal instrument is used for a long time are solved.

Description

technical field [0001] The invention belongs to the field of laser hair removal instruments, and in particular relates to a control method of a laser hair removal instrument. Background technique [0002] The principle of the laser hair removal device is to enable the laser to pass through the surface of the skin and reach the root follicles of the hair through reasonable laser wavelength, energy, and pulse width. The light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus causing the hair to lose its ability to regenerate. Because the device is a relatively high-power device, it generates a large amount of heat. After a long period of continuous work, the temperature of the device will be too high and the device will work abnormally. It can even burn human tissue, causing irreversible and permanent damage. At present, the existing technology monitors the temperature on the surface of the hair removal head to judge whether the te...
