The power switch 106 is also a push button. The second side surface and the third side surface are positioned at thumb operable positions when being held, and the first side surface is positioned at four-finger operable (pressing operation) positions when being held. The invention adopts the push button, and the button position is set to fully consider ergonomics and use experience, so that the operation of a user is more convenient, and the switching of a windshield, heat and the like can be realized by one hand.

The handle 102 is internally provided with a circuit board, and the circuit board is provided with a controller, and the circuit board is respectively connected with a heating device, a fan device, a power line 101, a power switch 106, an air speed button 103, a heat button 104, a compound button 105, an air duct heat and cold switching button 109, a handle heat and cold switching button 1013 and a functional display screen 107. The dryer cold-hot switch button 109 and the handle cold-hot switch button 1013 are connected with a circuit board in parallel. The heating device is provided with a temperature sensor which is connected with the circuit board. The fan device is provided with an anemometer which is connected with the circuit board. All buttons, a functional display screen, a fan device and a connection control mode of the heating device and the circuit board are all in the prior art, and the gear switching of wind speed, heat and the like is realized through the buttons. The function display screen 107 adopts a function display color screen, and can display wind speed and temperature in real time.

The composite button 105 is connected with a chip, and the chip is connected with a circuit board; the chip is recorded with temperature and wind speed in three modes of quick drying, modeling and shaping. The compound button 105 is capable of switching three modes, quick-drying, styling and styling, each mode switching comprising switching of wind speed and heat, which is achieved by a conventional design requiring multiple keys. The optimal temperature and wind speed numerical parameters of the three modes of quick drying, modeling and shaping are recorded on the chip, wherein the wind speed and the heat reach through market investigation and field test. When the hairstyler uses, the quick drying, shaping and setting functions are realized in sequence by only slightly pressing the composite button 105. In the default state, i.e. when the stylist is turned on, the compound button 105 is in the quick-dry mode; the stylist presses the following compound button 105 and the hair dryer is in styling mode; pressing the compound button 105 again, the blower is in the setting mode. And then pressing the compound button, the blower has a default quick-drying function. This cycle saves time and effort for the stylist and the number of buttons and the amount of space at the handle of the hair dryer. By using the compound button 105, an optimized combination of various heat and wind speed magnitudes is achieved. It is particularly helpful to the primary hairstylist that the temperature and wind speed required for various styling can be explored without long fumbling for the hairstylist just entering the hair styling and haircut industry.

The wind speed button 103 and the heat button 104 are both in a straight shape. The wind speed or heat can be increased and decreased through the circuit board at the two ends of the straight line shape respectively, the wind speed or heat is increased when a hairstylist presses the top of the straight line-shaped button head, and the wind speed or heat is decreased when the hairstylist presses the bottom of the straight line-shaped button; the operation of a hairstyler is convenient, and the space at the handle of the electric hair drier is saved.

The cold-hot switching key is only one key arranged on the handle in the traditional design, so that when a hairstyler needs to hold the air duct by hand for modeling and shaping operation in haircut, the cold-hot switching key on the handle needs to be operated by another hand to realize cold-hot switching. The invention sets a cold-hot switching button on the handle and the air duct, and the two buttons are connected in parallel, so that when a hairstylist holds the air duct to make hair, the cold-hot switching button 109 of the air duct can be pressed by the held hand to realize cold-hot switching, and when the hairstylist holds the handle to operate, the cold-hot switching button 1013 of the handle can be pressed by the held hand to realize cold-hot switching. By adopting the double cold and hot switch, the problem that a hairstylist has to operate the cold and hot switch with both hands when making a hairstyle is solved conveniently.

The cross section of the diffusion housing 404 is circular and the side cross section is trapezoidal. Fluid energy is reduced by arranging the flow passage elbow and the screen, meanwhile, the cross section area of an air outlet flow passage is increased by arranging the main diffusion chamber 4013 and the internal diffusion chamber, and under the condition that the flow rate is unchanged, partial dynamic pressure of air is converted into static pressure, so that the gas flow rate is integrally slowed down.

Considering that the heating wire of the electric hair drier has high power, the radiation under alternating current is high. In addition, the wind temperature of the hair blown by the traditional hair dryer has a great relationship with the distance between the hair and the air outlet. The distance is far, the temperature is low, the distance is near, and the temperature is high.

The power of the heating wire is regulated instantaneously through far infrared detection of the temperature of the hair. The temperature and distance of the hair blown by the hair blowing agent are not greatly related. That is, in a certain range, the temperature of the hair blown by the hairstyler is not related to the distance of the hair blowing by the hairstyler. Only with respect to the initial temperature set by the stylist. At this time, the heating wire power is adjusted to be constant temperature while moving along with the operation of the hairstyler. However, when the electromagnetic radiation of the heating wire is emitted through the air outlet, the ceramic protective net 316 shields the electromagnetic radiation, so that the radiation protection effect is achieved.
