The rotating frame 210 includes a rotating part 211 and a connecting part 212. By setting the rotating part 211 to be sleeved in the guide cylinder 120, the rotating part 211 can rotate in the guide cylinder 120. The air guide wheel body 220 is provided with a mounting hole 221, the connecting part 212 passes through the mounting hole 221, and the air guide wheel body 220 is fixedly connected to the rotating part 211 through a fastener 230. The output shaft of the motor 130 is fixedly connected to the connecting part 212, so that the motor 130 can drive the rotating frame 210 to rotate, and thus can drive the air guide wheel body 220 to rotate.

[0032] It can be understood that, referring to Figure 2 and Figure 3 , a guide groove 121 is provided around the outer wall of the guide cylinder 120, and a guide bar 213 protrudes from the rotating part 211, and the guide bar 213 is located in the guide groove 121. The guide groove 121 is arranged around the outer wall of the guide cylinder 120, and the guide bar 213 protrudes from the rotating part 211. By arranging the guide bar 213 in the guide groove 121, the guide bar 213 can slide in the guide groove 121, so that the rotating frame 210 can rotate stably in the guide cylinder 120, preventing the rotating frame 210 from slipping out of the guide cylinder 120 and improving the rotation stability of the air guide wheel body 220.

[0033] In addition, by arranging the guide bar 213 in the guide groove 121, it is convenient to position the rotating frame 210 on the guide cylinder 120, so that the fastener 230 can easily tighten the air guide wheel body 220 and the rotating frame 210 together, improving the installation convenience of the air guide wheel body 220.

[0034] Specifically, referring to Figure 2 and Figure 3 , in the axial section of the rotating part 211, the shape of the guide bar 213 is semi-circular, and the guide groove 121 matches the shape of the guide bar 213. In the axial section of the rotating part 211, the shape of the guide bar 213 is semi-circular to increase the surface area of the guide bar 213, and the shape of the guide groove 121 matches the shape of the guide bar 213, so that the guide bar 213 can be closely attached to the guide groove 121, improving the connection stability between the guide bar 213 and the guide groove 121, and reducing the stress concentration, enabling the rotating frame 210 to be stable on the guide cylinder 120 and improving the position stability of the air guide wheel body 220.

[0035] In addition, by setting the shape of the guide bar 213 to be semi-circular, the rotating part 211 can be smoothly sleeved on the guide cylinder 120, facilitating the guide cylinder 120 to expand the rotating part 211 and preventing the guide bar 213 from getting stuck at the end face of the guide cylinder 120, improving the installation convenience of the rotating frame 210.
