Hair dryer construction and working principle are mainly used for hair drying and shaping, but it can also be used for local drying, heating and physiotherapy in laboratories, physiotherapy rooms, industrial production, art and other aspects. A cosmetic appliance for hair drying and shaping. Hair dryer-construction hair dryer is mainly composed of outer casing, electric motor, fan blade and electric heating hair dryer. The working principle is mainly used for hair drying and shaping, but it can also be used in laboratories, physiotherapy rooms, industrial production, art and so on. Partial drying, heating and physiotherapy. A cosmetic appliance for hair drying and shaping.
Hair dryer - working principle The motor and the blade are directly connected. After the power is turned on, the motor drives the fan blade to rotate. The air sucked in from the air inlet passes through the electric heating element and is controlled by the switch to become hot air or cold air sent from the air outlet. Usually, only when the motor is energized, the heating element can be turned on to avoid overheating and damage. The simple method of adjusting the air temperature by the blower is to rotate the baffle on the outer casing; when there is a control switch, the temperature can be adjusted by the splitter; when the PTC component is used, the temperature can be automatically controlled. Some hair dryers achieve stepless adjustment of wind temperature and air volume by changing the external power supply voltage. It is a combination of a set of heating wire and a small fan. When the power is applied, the heating wire generates heat, and the wind blown by the fan passes through the heating wire, and becomes hot air. If only a small fan rotates, and the heating wire is not hot, then the wind is only hot and not hot. The wind blown by the hair dryer is dry wind. If it is used for too long, it will easily cause water loss and heat damage. The secret of minimizing the damage is to use the towel to pat the moisture on the hair first. Combing your hair and then use a hair dryer.
