Meanwhile, when the main control board 18 receives the electrical signal each time, the light emitting color of the light source 2 is changed, so that the light emitting color of the light source 2 corresponds to the heating temperature of the heating device 15.
Through the above, it is difficult to find that, due to the fact that the travel switch, the key switch and the light source are arranged, the travel switch is provided with a shutdown gear and a plurality of wind speed gears, the motor of the hair dryer is closed through the shutdown gear, no wind is discharged, and the travel switch can be switched to any wind speed gear, so that the hair dryer can blow out wind with different speeds. And, key switch and main control board 18 electric connection realize heating device 15 heating temperature through key switch, let the wind of blowing out have different temperatures, satisfy different user demands. When the main control board 18 receives the electric signals output by the key switches each time, the light source luminescence color is changed, so that different colors are generated by the light sources of wind with different temperatures, color judgment is increased, a user can better judge the function of the hair dryer in use at the moment, the required function is safely selected, more convenience is brought to the user, and the using sensory degree is improved. Meanwhile, the travel switch and the key switch are different in use methods, different functions are realized, and a user can better distinguish the functions and select the functions required by the user.
Specifically, in the present embodiment, as shown in fig. 1, 2 and 6, the main control board 18 is pre-stored with temperature values of two different temperatures heated by the heating device 15, the two temperature values respectively generate high temperature wind and medium temperature wind, and cold wind is generated when the heating device 15 does not heat. The main control board 18 calculates the duration of the output electric signal of the key switch while receiving the electric signal output by the key switch, and after the calculated duration of the output electric signal of the key switch is less than or equal to the preset duration, the main control board 18 invokes a temperature value different from the current temperature value of the heating device 15 to control the heating device 15. In order to match with the three kinds of temperature wind, the light source 2 comprises three light emitting elements electrically connected with the switch circuit board 1, and is three Light Emitting Diode (LED) lamps, wherein each LED lamp emits red, yellow and blue light when being lightened, and a high Wen Fengshi red lamp is lightened, a yellow lamp is lightened when generating medium temperature wind, and a blue lamp is lightened when generating cold wind. In actual use, as shown in fig. 1, 2 and 7, the air blown by the hairdryer is high Wen Fenshi, the keycap 5 is pressed, the micro switch 3 is triggered, the keycap 5 is released when the micro switch 3 is pressed for 1s, the micro switch 3 sends an electric signal to the main control board 18 in the 1s, after the main control board 18 receives the electric signal, the heating device 15 is controlled to reduce the heating temperature, and the hairdryer blows medium-temperature air, and at the moment, the color of the light source 2 is changed from red to yellow. Similarly, when the air blown out by the hair dryer is at medium temperature, the key cap 5 is pressed, the micro switch 3 is triggered, when the key cap 5 is released after the key cap is pressed for 1s, the micro switch 3 sends an electric signal to the main control board 18, after the main control board 18 receives the electric signal, the heating device 15 is controlled to increase the heating temperature, so that the hair dryer blows out high-temperature air, and the color of the light source 2 is changed from yellow to red at the moment. In addition, when the air blown out by the hair dryer is medium-temperature air or high Wen Fengshi, the time length of the long key cap 5 is longer than 1s, the micro switch 3 always sends an electric signal to the main control board 18 within the time length of more than 1s, and the main control board 18 controls the heating device 15 to be closed, so that the hair dryer blows out cold air. According to actual demands, 1s can be changed into 2s or 3s, and the change is carried out according to actual use demands.

That is, if the air blown from the hair dryer is cold air, the key cap 5 is pressed down again, and at this time, the main control board 18 receives the electric signal and then returns the control heating device 15 to a state of heating before being turned off. If high-temperature wind is blown before cold wind is blown, the key cap 5 is pressed down, the main control board 18 controls the heating device 15 to generate high temperature, the hair dryer blows the high-temperature wind, and the color of the light source 2 is changed into red; if the middle-temperature air is blown before the cold air is blown, the key cap 5 is pressed down, and the main control board 18 controls the heating device 15 to generate the middle temperature, so that the hair dryer blows the middle-temperature air, and the color of the light source 2 is changed into yellow.
Further, as shown in fig. 1, 2 and 6, the main control board 18 calls the temperature value previously called to control the heating device 15 each time the travel switch is switched from the shutdown gear to any wind speed gear. That is, when the travel switch slides to the power-off position, the main control board 18 controls the motor and the heating device 15 to be turned off, and then moves the travel switch to slide to the middle or high wind speed position, and the main control board 18 controls the motor to turn on and also controls the heating device 15 to return to the working state before power-off. If the heating device 15 is high temperature before shutdown, the blown wind is high temperature wind, and then the travel switch is slid to the middle wind speed gear or the high wind speed gear, the main control board 18 controls the heating device 15 to continue heating to generate high temperature, the high temperature wind is blown out, and meanwhile, the power supply 2 emits red light. If the heating device 15 heats before the power-off, the blown wind is middle temperature wind, and then the travel switch is slid to the middle speed gear or the high speed gear, the main control board 18 controls the heating device 15 to continuously heat to generate middle temperature, the middle temperature wind is blown out, and meanwhile, the power supply 2 emits yellow light. If the heating device 15 is turned off before the power-off, the blown air is cold air, and then the travel switch is slid to the middle wind speed or the high wind speed, the main control board 18 controls the heating device 15 not to work, the cold air is blown out, and meanwhile, the power supply 2 emits blue light.
A second embodiment of the invention relates to a hair dryer comprising the switching device of the first embodiment, the switching device being arranged on the handle of the hair dryer.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the invention and that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
