question 3: what kinds of hair dryers are there? Negative ion fans can neutralize the charges in the air to achieve the balance of charges, that is, eliminate static electricity in the air.
a normal fan has no function of eliminating static electricity.
Question 4: What kind of hair dryer is the motor? Guo Dun replied:
Hair dryer is a cosmetic appliance used for hair drying and shaping. But it can also be used for local drying, heating and physical therapy in laboratories, physical therapy rooms, industrial production and art design. Also known as hair dryer and hair dryer. According to the type of motor, it can be divided into three types: single-phase AC induction type, AC-DC series excitation type and permanent magnet DC type. According to the air supply mode, it can be divided into axial flow and centrifugal type. Compared with other five-star electrical appliances, the radiation intensity of hair dryer is not outstanding, but it is very harmful to human body because it is close to the scalp when used. In daily life, hair dryers should be used as little as possible to dry hair, and when the hair dryers are turned on and off, don't let the hair dryer face the scalp.
Although there are many types of hair dryers, their structures are similar, and they are all composed of a shell, a handle, a motor, a fan blade, an electric heating element, a windshield, a switch, a power cord, etc.
1. shell. It plays a protective role for internal parts and is also an external decoration.
2. Motors and blades. The motor is installed in the shell, and the blades are installed on the shaft end of the motor. When the motor rotates, air is sucked in from the air inlet and wind is blown out from the air outlet.
3. Electric heating element. The electric heating element of the hair dryer is wound with electric heating wire and installed at the air outlet of the hair dryer. The wind discharged by the motor is heated by the electric heating wire at the air outlet and turned into hot air. Some hair dryers are equipped with thermostats near the electric heating elements to cut off the circuit when the temperature exceeds the predetermined temperature, which plays a protective role.
4. Windshield. Some hair dryers have a circular wind shield at the air inlet to adjust the air intake. A hair dryer without a circular windshield can cover a part of the air inlet with a piece of paper, and the air intake can also be adjusted. When the air intake is small, the blown wind is hot, and when the air intake is large, the blown wind is not too hot. It should be noted that the tuyere should not be blocked too much, otherwise the motor will be damaged or the electric heating element will be burned out because of the high temperature.
5. switch. Generally, the hair dryer switch has three positions: hot air, cold air and stop. White usually means stop, red means hot air and blue means cold air.
In order to make the hair dryer play its due role in drying and setting, to use it correctly, reasonably and safely, and to prolong the service life of the appliance, the following matters should be paid attention to when blowing:
(1) The hair dryer must be used under the power supply voltage specified on the nameplate. For a hair dryer with a three-wire power cord, the grounding wire should be correctly connected.
(2) When using the hair dryer, the air inlet and outlet must be unobstructed, otherwise it will not only fail to achieve the use effect, but also cause overheating and burn out the appliance.
(3) When it is used to blow dry and wet hair, the air outlet of the hair dryer should be kept at a certain distance (not less than 5mm) from the hair to prevent the air outlet from blocking and burning the hair. At the same time, it is important to keep a certain distance for safety to avoid the water vapor generated during hair drying affecting the insulation strength and causing leakage.
(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 electric heating element first. Then let the residual heat of the electric heating element be blown out with the help of cold air, so as to reduce the internal temperature of the hair dryer, and then cut off all the power supply. This can slow down the aging of the internal insulation of the hair dryer and prolong the service life. At the same time, it is not easy to burn other objects when placed on the table.
(5) The electric hair dryer should not be used continuously for too long as possible, and should be used intermittently to avoid overheating and burning of electric heating elements and motors. When not in use, the hair dryer should be placed in a dry place, and it should not be placed in the open air or wet place. When it is taken out after long-term use, the insulation resistance should be checked first, and it can be used normally if it meets the requirements, so as to ensure the personal safety during use. Because there is dust in the air, although many hair dryers are equipped with a filter screen at the air inlet, which plays a protective role, they cannot prevent the dust with very small particles, and not all hair dryers have filter cloth. Therefore, it is necessary to clean the dust regularly to prevent blocking the air duct and damaging the components.
(6) Don't throw the hair dryer at will, because the electric heating element and motor will be damaged by mechanical impact, and don't disassemble it easily to avoid damaging the parts. In order to ensure the normal use of the hair dryer, lubricating oil should be added to the bearing part and other rotating parts of the motor regularly, but the amount of oil should not be too much, so as not to flow to the coil and cause failure.
the air sucked from the air inlet passes through the electric heating element and is controlled by the switch, and becomes hot air or cold air sent from the air outlet. Usually, the electric heating element can only be turned on when the motor is energized to avoid overheating and damage to the parts. The simple way to adjust the air temperature of the blower is to turn the baffle on the shell; When there is a control switch, the temperature can be adjusted in stages; Temperature can be controlled automatically when PTC element is used.
