1. How to choose a hair dryer

A hair dryer is an electrical appliance used to dry and shape hair, and is very popular in daily life. The following will introduce several parameters that you should pay attention to when purchasing a hair dryer to help you easily choose the most suitable one:

1. Power parameters

Currently on the market The power of hair dryers is generally 250 to 1200 watts. The best hair dryer for home use is about 600 to 800 watts, which is safer.

2. Temperature parameters

Hair dryers generally have more than two temperature settings and a built-in fan with excellent efficiency, which can enhance the wind force and shorten the drying time.

3. Does it have a device to prevent overheating?

A good hair dryer is equipped with a device to prevent overheating and control the wind temperature to protect the hair.

4. Whether it has a diffusion nozzle

High-end hair dryers are equipped with a diffusion nozzle. The hot air is transmitted to the hair roots through multiple comb teeth. The heat is evenly distributed and the wind is soft. Effectively protect hair and make hair healthier.

5. Is it foldable?

Most people on business trips choose foldable hair dryers. The handles are foldable and wall-mounted, making them easy to carry. It is equipped with an air nozzle for styling hair, which can be disassembled and installed at will. It has two levels of wind speed and overheating automatic power-off protection function.

6. Does it have temperature control function?

The newly launched logical temperature control hair dryer is the crystallization of high-tech products. An infrared temperature sensor is installed in the center of the air nozzle to monitor it at any time. The temperature changes of the hair are immediately transmitted to the electronic temperature controller inside the hair dryer to adjust the temperature of the hair dryer. It has the function of automatically adjusting the temperature and preserving the natural moisture of the hair, making the hair healthier, glossier and fuller

2. The use and maintenance of the hair dryer

In order to ensure that the hair dryer can play its role in drying and styling, to use it correctly, reasonably and safely, and to extend the life of the appliance, it is necessary to use the hair dryer before blowing. The following items should be noted when using:

(1) The hair dryer must be used under the power supply voltage specified on the nameplate. For hair dryers with a three-wire power cord, the ground wire should be connected correctly.

(2) When using the hair dryer, the air inlet and outlet must be unobstructed. Otherwise, not only will the use effect not be achieved, but it will also cause overheating and burn out the appliance.

(3) When used to dry wet hair, the air outlet of the hair dryer should be kept at a certain distance from the hair (not less than 50mm) to prevent the air outlet from being blocked and the hair from being burned. At the same time, it is important to avoid the water vapor generated when blow-drying hair from affecting the insulation strength and causing leakage. Therefore, keeping a certain distance is important for safety.

(4) Before using the hair dryer, try to switch the hair dryer from "hot" to "cold" so that the power supply to the electric heating element can be cut off first. Then let the remaining heat of the electric heating element be blown out by the cold air to reduce the internal temperature of the hair dryer, and then cut off all power. This can slow down the aging of the hair dryer's internal insulation and extend its service life. At the same time, it is not easy to burn other objects when placed on the table.

(5) Try not to use the hair dryer continuously for too long. It should be used intermittently to prevent the heating element and motor from overheating and burning out.

The hair dryer should be placed in a dry place when not in use. It should not be placed in the open air or in humid places. When taking it out after being unused for a long time, the insulation resistance should be checked first. If it meets the requirements, it can be used normally to ensure that it can be used normally. personal safety.

Because there is dust in the air, although many hair dryers are equipped with filters at the air inlets for protection, they cannot prevent dust with very small particles, and not all hair dryers have filter cloths. For this reason, dust must be cleaned regularly to prevent clogging of air ducts and damaging components.

Do not throw the hair dryer casually. The heating element and motor may be damaged due to mechanical impact. At the same time, do not disassemble it easily to avoid damaging the components. In order to ensure the normal use of the hair dryer, lubricating oil should be regularly added to the bearing part and other rotating parts of the motor, but the amount of oil should not be too much to avoid flowing to the coil and causing failure.
