Meanwhile, the second limit part 4 interferes with the crank 21 to prevent the crank 21 from rotating counterclockwise continuously due to overshoot, so that the PTC heating device 8 is ensured to stay at the preset position of the air outlet 72, and the second monitoring switch 6 and the synchronous motor are ensured not to be damaged. When the user starts the natural wind or cold wind mode, the synchronous motor drives the crank 21 to rotate clockwise, and the PTC heating device 8 slides to the parking pad 73 by being pulled by the transmission rod 9. When the crank 21 rotates to the position of the first monitoring switch 5, the tip 22 pushes the first transmission element 51, so that the first monitoring switch 5 disconnects the electrical connection between the synchronous motor and the control circuit. Meanwhile, the first limiting part 3 interferes with the crank 21 to prevent the crank 21 from continuously rotating clockwise due to overshoot, so that the PTC heating device 8 is ensured to stay at the preset position of the parking pad 73, and the first monitoring switch 5 and the synchronous motor are ensured not to be damaged.
