EspañaThe working principle of the temperature control switch of the hair dryer
The temperature control switch of the hair dryer is generally controlled by a bimetallic temperature controller. The bimetallic temperature controller is mainly composed of a bimetallic strip and a contact switch. The shape of the bimetallic strip will change with the change of temperature. When it is in a normal temperature state, the contact of the bimetallic strip is closed. When the temperature rises, the bimetallic strip deforms after reaching the induction temperature of the bimetallic strip, and the contact will be disconnected to achieve temperature control.

When the hair dryer is turned off, the two contacts of the bimetal temperature controller ST are in a conductive state. When the hair dryer is energized and rises to the high temperature block, the hair dryer works normally. When it reaches a temperature, the two contacts of the bimetal temperature controller If the contact is separated into a disconnected state, the electric blower will stop heating and enter the insulation state. When its temperature drops to a certain temperature, the metal shrapnel of the bimetallic temperature controller becomes conductive again and can continue to heat.
How to use the hair dryer correctly
1. After washing the hair, wipe off the excess water with a dry towel, then divide the hair well, and fix the outer hair on the top of the head with a clip. Because it can dry the hair better.

2. Remove the hair on the top of the head, divide it into two parts and dry it, insert it into the hair with both hands and comb it, and dry it with a hair dryer.
3. Divide the lower part of the hair into two sides, spread 5 fingers and insert them into the hair, while using your fingers to comb from the head to the end, while drying with a hair dryer.
4. Divide the hair on the side into two parts with the ear as the boundary. Use a roller comb to slowly comb the hair from the root to the tip, and place the hair dryer on the side to blow the air. The hair behind the ears is treated in the same way.
Use and maintenance of electric hair dryer
(1) The blower must be used under the power supply voltage specified on the nameplate. For the hair dryer with a three-wire power cord, the grounding wire should be connected correctly.
(2) When using the hair dryer, the air inlet and outlet must be kept unobstructed, otherwise the effect will not be achieved, and the appliance will be burnt out due to overheating.
(3) When it is used to dry wet hair, the air outlet of the hair dryer should be at a certain distance from the hair (not less than 50mm) to prevent clogging of the air outlet and scorching the hair. At the same time, avoid the water vapor generated when drying hair affects the insulation strength and cause leakage, so keeping a certain distance is important for safety.
(4) Before using the hair dryer, try to switch the hair dryer from "hot" to "cold" first, so as to cut off the power supply of the heating element first. Then let the remaining heat of the electric heating element be blown out with the help of cold wind, so that the internal temperature of the hair dryer is lowered, and then all the power is cut off. This can slow down the aging of the internal insulation of the hair dryer and prolong its service life. At the same time, it is not easy to burn other objects when placed on the table.
(5) The hair dryer should not be used continuously for too long as much as possible, and 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, and should not be placed in the open or humid place. When taking it out after long-term use, check the insulation resistance first. It can be used normally when it meets the requirements to ensure personal safety during use. Due to the dust in the air, although many hair dryers are equipped with a filter at the air inlet for protection, they cannot prevent dust with very small particles, and not all hair dryers have filter cloth. For this reason, dust must be cleaned regularly to prevent blockage of air ducts and damage to components.
(6) Do not throw the hair dryer at will. The heating element and the motor will be damaged by mechanical impact. At the same time, do not disassemble it easily to avoid damage to the components. In order to ensure the normal use of the hair dryer, the bearing part and other rotating parts of the motor should be filled with lubricating oil regularly, but the amount of oil should not be too much, so as to avoid flowing into the coil and causing malfunction.
