The use of the hair dryer shorten the time of moist and hair drying, which reduces peoples chances of infection.The convenience of the hair dryness to our lives is beyond doubt. Because the hair dryer uses electricity as the energy, long -term use will also have certain disadvantages.
The role of a hair dryer
Many friends choose not to blow hair and blow their hair. In addition to being damaged by the hair quality, it also causes radiation problems due to a hair dryer.
The hair dryer is a high -radiation household appliance. When it is turned on and closed, its radiation volume is the largest. Different hair dryers have different radiating amounts.The detection data of the monitoring center knows that the hair dryer of 000W is about 350mg of the normal home, and the radiation values ??we often use are about 45mg and 100mg, respectively. It can be seen that the radiation of the hair dryer is extremely greatEssence
Do n’t be afraid of friends who have habitual use habits. The maximum hair drying radiation is the back end of the hair dryer. The safety factor of the air outlet is much higher. When people are 3 cm from the outlet, the low -frequency radiation volume is 42.8 mg, about 8-10 about 8-10At centime, the radiation volume is only 5.5mg.
However, proper use of hair dryers can reduce its damage to the human body, because the largest part of the hair dryer is the hair dryer back end, and the air outlet of the hair dryer is much higher than the safety factor.At 3 cm from the outlet, the low -frequency radiation volume is 42.8 mg, and further, about 8-10 cm, that is, the distance between our usually blows hair. The radiation amount here is only 5.5mg.In the daily use of hair dryers, the use of hair dryers is much greater than this distance.

Blow the hair partition
Baggers use hair dryers to blow the hair partitions, divide their hair into two layers of up and down, first blow dry the lower layers of hair, and then blow dry on the wet method above the head, so that the hair on the surface will not blow too dry.

Just after washing your head, the wet hair scales are open. Blowing the direction of the growth of the hair can be closed, otherwise the hair scales will be opened, and the hair will be more frizzy.

Holding a hair dryer in a static area for a long time can easily cause damage to hair. The correct method is to start from the top of the head. At the same time, the hair is used with one hand, and the other hand keeps moving the hair dryer.
Hair dryer structure
The working principle of a hair dryer: The hair dryer is to drive the rotor by driving the rotor directly by the motor.During the rotation of the wind, the air was inhaled from the inlet, and the centrifugal air flow was blown out from the front of the fans.The heating wire is powered on the heat. When the air is used to blow the hot air through the heating wire loaded on the heating stent in the wind; if the heating wire does not pass the electric heating, it will blow out the cold wind.To achieve the purpose of drying.
