BLDC motor hair dryer manufacture.Negative ion hair dryer

　　The negative ion hair dryer is mainly equipped with a negative ion generator and a semiconductor refrigeration device, so that when the hair dryer is working, it can generate negatively charged ion particles (generated by the negative ion generator) and water vapor particles (generated by the semiconductor refrigeration device), neutralize the common positive charge in the hair, thus smoothing the hair, making it smooth and smooth, and also eliminating static electricity. Make hair smoother and easier to comb, resulting in a more ideal styling effect.

　　The hair dryer heats up during operation, and the air blown out makes the hair dry. It is also necessary to use a comb during use, which makes it easy for the hair to generate static electricity. Static electricity can cause the hair to deform, bend, or curl up. The negative ion fan has a specially designed mesh line inside, and the air blown out by the negative ion generator carries negative ions, so as not to generate static electricity and not harm the hair.

　　A negative ion generator is a device that generates air negative ions. The device processes the input DC or AC power through EMI processing circuits and lightning protection circuits, and then uses pulse circuits to limit overvoltage and current; High and low voltage isolation and other circuits are elevated to AC high voltage, and then purified DC negative high voltage is obtained through rectification and filtering with special grade electronic materials. The DC negative high voltage is connected to the release tip made of metal or carbon elements, and high corona is generated using the tip DC high voltage, releasing a large number of electrons (e -) at high speed. However, electrons cannot exist in the air for a long time (the existing electron lifetime is only nS level), and will be immediately captured by oxygen molecules (O2) in the air, This generates air negative ions. According to reports, there are already more advanced negative ion release tips: nanon fullerene negative ion release tips, which can generate pure negative ions. Air negative ions can be divided into three types by volume: light, medium, and heavy ions. The diameter of light ions is about 0.00001cm, and they move faster in an electric field, ranging from 1-2 cm2/V.S. In nature or ordinary environments, they have a mobility greater than 0.4 cm2/(V.s) and are small particle sized negative ions. The diameter of heavy negative ions is about 0.0001cm, and they move slower in an electric field, only 0.0005 cm2/V.S. In nature or ordinary environments, negative ions with a particle size of less than 0.04 cm2/(V.s) are classified as large particle size negative ions, while the size and activity of medium particle size negative ions are between light and heavy ions.
