Electric hair dryer in addition to drying hair, but also hair shaping, hair maintenance and other functions.
Therefore, the selection of electric hair dryer is a technical work. So is there any method, skill or standard for the selection of electric hair dryer?
What parameters should electric hair dryer choose?
Mainly from the speed, noise and life of these aspects to consider. The greater the power of the electric hair dryer, the better, the greater the power, the faster the speed, the greater the air volume. However, due to the size, weight and noise factors, electric hair dryer power will be greatly limited. Therefore, under the condition of reasonable volume, weight and noise, the greater the power, the better.
After all, the air volume can determine the speed of hair drying, which is the core function of a hair dryer.
The speed of the hair dryer on the market varies from ten thousand revolutions to tens of thousands of revolutions, and a well-known brand is said to be able to reach 110,000 revolutions. Noise is always a difficult problem for hair dryer. Limited by technology, there is no reliable solution at present. Even the well-known brand of ultra-high speed inverter motor can not reduce the noise at work. The good news is that the general impression of the user is that the hair dryer is extremely noisy, so there is no need to think too much about the selection of less noise, unless there is a product that completely changes the user's perception.
The last thing to be considered is the life of the motor.
Because of the properties of the commutator, the life limit of the brushed DC motor is not too high. Thousands of hours is the limit, while the theoretical limit of the brushless DC motor can reach decades.
In addition, when selecting a motor for an electric hair dryer, other constraints such as cost, space size and special functions should be taken into account.
