Hair dryer is an electrical appliance that we have a hair plastic surgery as usual, it is mainly suitable for some physiotherapy, beauty salon, as usual career comparison commonly used, mainly the hair dryer of our usual career called hair dryer, but also according to the type of electric is unusually large, in the same ordinary career hair dryer is still very dangerous to the human body, Its radiation is not prominent, but the danger to hair when it is used is equally great.
According to his classification of grace, electricity in an ordinary life is also different from the effect of a hair dryer. The power is mainly the same in the ordinary life is also more than ah, as the ordinary family uses six hundred watts to eighteen hundred watts, and the hair shop uses the same ordinary control. So it is in an ordinary life to pay attention.
1, proof it uses the type of motor, can be divided into AC series, AC shield type and DC permanent magnet type.
The advantages of series excited hair dryer are large starting torque, high speed, suitable for manufacturing high-power hair dryer; The defect is that the noise is loud, and the commutator has a certain nuisance to the telecommunications equipment.
The advantages of the cover pole hair dryer are low noise, long life, and no nuisance to telecommunications equipment; The defects are low speed, poor starting performance, and large weight. The advantages of permanent magnet hair dryer are light weight, high speed, simple manufacturing process, low cost, cheap.
2. According to the way of use, there are hand-held and support hair dryers. Support type hair dryer can be placed on the table or hung on the wall to use, you can blow yourself.
3, according to the air supply mode, there are centrifugal hair dryer and axial flow hair dryer.
The centrifugal type relies on the electric motor to mobilize the wind blade to rotate, so that the air entering the hair dryer obtains inertial centrifugal force, and constantly exhausts the air. Its defect is that the crushing wind does not all flow through the electric motor, the electric motor temperature higher; The advantage is lower noise.
The axial flow motor mobilizes the wind blade to rotate, pushes the air into the hair dryer to flow axially, and continuously exhausts the air. Its advantage is that all the rolling wind flows through the motor, the motor cooling condition is good, and the insulation is not easy to age; Its drawback is that it is noisy.
4, according to the material used in the shell, there are metal type hair dryer and plastic type hair dryer. Metal type hair dryers are hard and durable and can be subjected to higher temperatures. The plastic type hair dryer is light in weight and has good insulation performance, but it is easy to age and has poor high temperature resistance.
The above is the power of the hair dryer, which is the same as the ordinary life and the same as the ordinary family uses six hundred watts to eighteen hundred watts, according to the abnormal number of electric types, in the same ordinary life, the hair dryer is still very dangerous to the human body, its radiation is not prominent, then it is in use when the hair and hair risk is also compared to the big. As usual, choose to use less hair dryers and natural air drying is better.
