In the selection of the material of the air duct shell, metal (such as copper or cold-rolled iron plate) materials were used in the past to use thermoplastic engineering materials (mainly polycarbonate, modified polystyrene, modified polypropylene, etc.
The advantages of shaded-pole hair dryers are low noise, long life, and no interference to telecommunications equipment; the disadvantages are low speed, poor starting performance, and heavy weight. Its disadvantage is that the exhausted wind does not flow through the motor, and the temperature of the motor is higher; the advantage is that the noise is lower. The hair dryer is used to achieve the purpose of drying and shaping.
Some hair dryers are equipped with a thermostat near the heating element to cut off the circuit when the temperature exceeds a predetermined temperature to protect it. When the motor rotates, air is drawn in from the air inlet, and wind is blown out from the air outlet. The pedestal hair dryer can be used on the table or hung on the wall, and you can blow it yourself. When the wind blade rotates, air is sucked in from the air inlet, and the resulting centrifugal air flow is blown out from the front nozzle of the wind tube.
Although there are many types of hair dryers, China hair straightener brush the structure is similar, and they are all composed of shell, handle, motor, fan blade, electric heating element, wind deflector, switch, power cord and so on. Role: automatically cut off the circuit. The axial flow motor drives the fan blades to rotate, pushing the air entering the blower to flow axially, and continuously exhausting the air. The selector switch on the handle of the hair dryer is generally divided into three gears, namely, off gear, cold wind gear, and hot wind gear, and there are signs with white, blue, and red colors. 2. The metal hair dryer is durable and can withstand higher temperatures
