When the hair dryer continues to slide in the first direction, the resistance on the first circuit board 15 changes continuously, and the current acting on the motor 2 changes continuously, so that the rotation speed of the motor 2 changes continuously, and the gear position changes continuously. On the contrary, when sliding in the direction opposite to the first direction, the resistance on the first circuit board 15 changes continuously in the opposite direction, and the circuit acting on the motor 2 changes continuously in the opposite direction, so that the rotation speed of the motor 2 changes continuously in the opposite direction, and the gear position changes continuously in the opposite direction, and the hair dryer is turned off in the first position. When the sliding key 12 is in any position, when the acceleration key 11 is pressed, the current of the motor 2 increases rapidly, and the rotation speed of the motor 2 increases rapidly, and the maximum rotation speed is achieved, so that the maximum gear position of the hair dryer is obtained, and the maximum air volume is achieved.
