Application of MOS Tube in Cosmetic Instrument

       The laser hair removal instrument is based on the principle of selective photothermal dynamics, By reasonably adjusting the pulse width of laser wavelength and energy, the laser can pass through the skin surface to reach the root hair follicle, and the light energy is absorbed and converted into heat energy that destroys the hair follicle tissue, thus making the hair lose its regeneration ability and may also damage the surrounding tissues, with light tingling.

   
 Hair removal instrument can generally be divided into the following categories, and the classification standard is the core technology adopted by the instrument. 

1. Laser hair removal instruments are mostly used in beauty salons, hospitals and other medical institutions, but there are few domestic laser hair removal instruments, such as tria, because it has great energy and strong pain when used, and it is likely to burn if it is not assisted by professionals. 

2. IPL strong pulse light hair removal instrument, most household hair removal instruments on the market now use this kind, such as Mujin. Its energy is smaller than that of laser hair removal instrument, but the pain is obvious when used. It is more suitable for limbs and back. If it is used to remove armpits or bikini areas, it may hurt. Girls with sensitive muscles are not recommended to use it. 

3. HPL Home Pulse Light Hair Removal Instrument. HPL is the core technology specially developed for household hair removal instrument. It has mild performance and high hair removal efficiency, which is equivalent to an upgraded version of IPL, and can be used with confidence for sensitive muscles and healthy skin. However, because this technology is patented at present, many household hair removal instruments do not have the right to use it, and now a few brands in the market have this technology, such as Golan hair removal instruments. 

Generally speaking, both laser hair removal instruments and pulsed light hair removal instruments belong to the category of optical hair removal. The core technologies they adopt directly affect the hair removal effect and use experience. After all, they are instruments that directly act on the skin, and safety is still very important. 

Introduction of Hair Removal Instrument Scheme 

The main board scheme of laser hair removal instrument is divided into 12V and 24V schemes. In terms of total volume, shipments are all good. 

The 24V scheme is as follows:  

The power supply is matched with 24V 1.5 A adapter. Two driving circuits are adopted, one of which is step-down to MCU, and the MCU matched here is controlled by CMS8S6990N TSSOP20 from Medium and Micro Semiconductor. The other MOS matched here through MOS is WSF20N15 from Taiwan Weishuo Semiconductor, which presses the 24V power supply to 400V through the transformer to charge the large capacitor, and emits 10,000 volts and 100 amps of current from the large capacitor, and the time is controlled in one millisecond. Light the lamp tube. 

Introduction of Hair Removal Instrument Scheme 

The 12V scheme is as follows: 

The power supply is matched with 12V 3A adapter. Two driving circuits are also adopted, one of which is step-down to MCU, and the MCU matched here is controlled by SC8F2892B SOP16 from China Micro Semiconductor. The other MOS matched here through MOS is WSF40N10 from Taiwan Weishuo Semiconductor. The 12V power supply is raised by 400V through the transformer to charge the large capacitor. When working, the current of 10,000 volts and 100 amps is emitted from the large capacitor, and the time is controlled in one millisecond. Light the lamp tube. 

Scheme of radio frequency introduction instrument 

Portable radio frequency introduction instrument needle-free plastic beauty instrument whitening, firming and lifting beauty instrument Home introduction instrument applies high-tech full computer\ "living energy needle-free plastic beauty instrument\" and adopts\ "point-to-surface\" ultra-micro penetration technology to deliver high-energy needle-free plastic beauty products directly to the required skin tissues in a multi-point, uniform and in-depth manner. Let the high-energy needle-free beauty plastic stock solution containing various nutrients and active ingredients be quickly absorbed by skin tissues to play a role, thus producing curative effect. Promote skin metabolism and keep skin. 

Introduction of RF Introducer Scheme 

A single lithium battery 18650 is used for power supply, and 3.7 V is boosted to 5V for MCU, where MCU comes from CMS8S6990N TSSOP20 of Medium and Micro Semiconductor. The output part is pushed into the MOS driver through the MCU modulation signal, and the WSF40N10 power tube is pushed by the driver to work and output to the port of the acting component, so as to realize the intelligent export to the human body action. The working current is in tens of microamperes and the voltage is about 160V.
