Pay attention to the quality of the hair dryer and use it carefully
Posted by Admin | 23 Dec
I believe that hair dryers are not unfamiliar to everyone, especially in winter, if your hair is not easy to dry after washing, you will use a hair dryer to blow it.
In the era of "black technology" of hair dryers, negative ions, water ions, hair dryers and beauty machines emerge in endlessly, but even the best hair dryers can't stand the wrong way of using them, so today we will talk about some things about hair dryers. The hair dryer is improper, and the accident mentioned above is really a matter of minutes.
Open the search website, enter "hair dryer fire" to search, you will find that whether it is a quality problem or a safety accident caused by improper use is no longer a case!
In addition to accidents caused by quality problems, the hair dryer is heated and burned after being used for too long. Some people forget to turn off the power or pull the plug after use and cause fires. Some people will always ignore the potential safety hazards of incorrect use of the hair dryer.
In the previous risk monitoring of the hair dryer, the experimenters found that if there is no overheat protection device, when the hair dryer is drying the cotton cloth, the temperature of the cotton cloth rapidly rises from normal temperature to 200 to 300 ℃ in just 8 seconds, and then The cotton cloth began to smoke with sparks.
So if you don't pay attention, the hair dryer will turn into a fire gun in minutes, and the degree of danger can be imagined.
So what kind of operation will make the hair dryer self-ignite?
First of all, let us understand the characteristics of the hair dryer: high power, plastic shell body, so it heats up quickly and radiates slowly.
The working principle of the electric hair dryer is that there is a motor inside the electric hair dryer. The rotation of the motor drives the rotation of the fan blades to form an axial air flow. The air is sent to the inside of the hair dryer. The air is heated by the heating element, and then the hot air is heated by the blower. Send out to heat and dry the hair.
Simply understand that the hair dryer motor draws in air from the air inlet at the back, is heated by the internal heating wire, and then blows out hot air from the front air outlet.
Therefore, ensuring that the air inlet and outlet are unblocked is a key to the normal operation of the hair dryer. Since the heating speed of the heating wire is very rapid, if the user uses hot air for a long time to dry or cover the front and rear air outlets.
The heat inside the hair dryer accumulates and cannot be dissipated, and the temperature rises instantly, and the heating wire will burn and become a "fire gun". If you don't pay attention, you may ignite your hair or other furniture, so don't be careless when using a hair dryer!
