[0037] The circuit board 3 is provided with a control program for controlling the operation of the motor of the hair dryer 1, and a plurality of air speed gears 31 are arranged on the circuit board 3, and the motor is controlled to change speed to realize different air volume.

[0038] The push button 2 is fixedly arranged with a gear switching part 21 in the direction of the circuit board 3, and the push button 2 drives the gear switching part 21 to switch on different air speed gears 31 through sliding movement, so as to realize the switching of different air volume.

[0039] As Figure 2 The sliding structure of the push button 2 comprises a sliding guide groove 12 arranged on the rear end cover 11 of the hair dryer 1, the push button 2 is installed in the sliding guide groove 12 and slides along the length direction of the sliding guide groove 12, so as to realize the sliding switch adjustment of the push button 2.

[0040] In the structure of the sliding air volume adjusting part provided by the application, the gear switching part 21 is an electrode sheet, which can adopt a hardware contact electrode spring sheet, the electrode sheet is fixed on the push button 2, and the push button 2 slides back and forth in the sliding guide groove 12 along the track of the sliding guide groove 12.

[0041] As Figure 4 The fixing mode of the electrode sheet is to open four small holes on the electrode sheet, four positioning columns are arranged on the push button 2, and the holes on the electrode sheet are sleeved into the positioning columns and then fixed by hot glue.

[0042] As Figure 3The electrode piece setting includes two electrode positions, as the contact end 22 of the gear position adjusting switch, and the wind speed gears 31 on the circuit board 3 are provided with two contact conductors corresponding to the positions of the two electrode positions, which are divided into a first contact conductor 32 and a second contact conductor 33, wherein the first contact conductor 32 connects all the wind speed gears 31 to form a whole, which is a long contact conductor, and the second contact conductor 33 is divided into several sections according to the interval of the wind speed gears 31, which is a short contact conductor.

[0043] The second contact conductor 33 has a lead connected to the control chip on the circuit board 3 at each interval, and the two contact conductors are both arranged below the sliding guide groove 12, and the gear switching piece 21 is in contact or misaligned with the two contact conductors during sliding, one of the two contact ends 22 is in long contact with the first contact conductor 32, and the two are always in contact during the sliding of the push button 2, and the other of the two contact ends 22 is in short contact with the second contact conductor 33, and the two are in contact and misaligned alternately during the sliding of the push button 2, to form a switch control.

[0044] Preferably, the first contact conductor 32 provided by the present application is a conductive strip, and the material of the conductive strip is required to be wear-resistant, and the second contact conductor 33 is a copper foil point, which is distributed at equal intervals along the groove at the corresponding sliding guide groove 12, corresponding to 1st, 2nd, 3rd, 4th, 5th and 6th gears, corresponding to 110,000 rpm of the turbine high-speed motor speed, in turn 60,000 rpm, 70,000 rpm, 80,000 rpm, 90,000 rpm, 100,000 rpm and 110,000 rpm, such as Figure 5 The gear setting is not limited to 6 gears, and the 110,000 rpm of the turbine high-speed motor speed can be adjusted at will.

[0045] The second contact conductor 33 distributed at intervals corresponds to different wind speed gears 31, and one wind speed gear 31 corresponds to one electrode speed.
