Working principle of vertical hair dryer
The hair dryer directly relies on the motor to drive the rotor to drive the blades to rotate. When the fan blades rotate, air is sucked in from the air inlet, and the centrifugal airflow formed thereby is blown out from the front nozzle of the air duct. When air passes through, if the heating wire installed on the heating bracket in the air nozzle has been electrified and heated, hot air will be blown out; If the selector switch does not energize the heating wire, it will blow out cold air. Electric hair dryer is a secondary way to achieve the purpose of drying and shaping.
The selector switch on the handle of the hair dryer is generally divided into three gears, namely, closed gear, cold gear and hot gear, with signs of white, blue and red. The handle of some hair dryers is also equipped with a motor speed switch, which is used to select the air volume and the temperature of hot air. On the back or side of the shell of various hair dryers, there is a rotatable circular air conditioning cover. By rotating the hood to adjust the cross section of the air inlet, the conveying wind speed and the temperature of hot air can be adjusted.
According to the use mode, there are hand-held and pedestal hair dryers. The base hair dryer can be placed on the table or hung on the wall, and you can blow your hair by yourself.
According to the air supply mode, there are centrifugal blowers and axial blowers. The centrifugal fan blades are driven by the motor to rotate, so that the air entering the blower obtains inertial centrifugal force and continuously discharges the air. Its disadvantages are that the exhausted wind does not completely flow through the motor, and the motor temperature is high; The advantage is low noise.
The axial motor drives the blades to rotate, which pushes the air entering the blower to flow axially and continuously discharges the air. Its advantages are that all the exhausted wind flows through the motor, the motor has good cooling conditions and the insulation is not easy to age. Its disadvantage is that it is noisy.
According to the material used in the shell, there are metal hair dryers and plastic hair dryers. Metal hair dryer is durable and resistant to high temperature. Plastic hair dryer has light weight and good thermal insulation performance, but it is easy to age and has poor high temperature resistance.
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 and a power cord.
The functions of each part of the vertical hair dryer are:
1, shell It protects the internal parts and is also an external decoration.
2. Motors and blades. The motor is installed in the shell, and the blades are installed at 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 an electric heating wire and installed at the air outlet of the hair dryer. The wind exhausted by the motor is heated by the electric heating wire at the air outlet and becomes hot air.
Some hair dryers are equipped with thermostats near the electric heating elements, which cut off the circuit when the temperature exceeds the predetermined temperature and play a protective role.
4. Windshield. Some hair dryers have a circular wind shield at the air inlet, which can adjust the air intake. A blower without a circular windshield can cover a part of the air inlet with a piece of paper, and the air inlet 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 will not be 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. General blower switch has three positions: hot air, cold air and vertical. White usually means "stop", red means "hot air" and blue means "cold air".
Some electric heating elements of hair dryers are composed of two or three electric heating wires, which are used to adjust the temperature and controlled by a selector switch.
Features of vertical hair dryer:
1, windy and low noise.
2. Motor mesh cover to prevent the motor from inhaling sundries.
3, telescopic pull rod with roller design, easy to carry and move.
4, poly shell, durable.
5. Adjust the wind speed in three gears to meet the needs of different environments.
The above is the vertical hair dryer that Bian Xiao introduced to you. By knowing whether you think the vertical hair dryer is much better than other hair dryers, it is still very good in function. Using vertical hair dryer can make our life more convenient and let us have enough free time to enjoy life. The vertical hair dryer is easy to use and suitable for us, which saves us more convenience. Bian Xiao's introduction ends here. I hope this introduction to Bian Xiao will help everyone, and I wish you a happy life!
