In some embodiments of the present invention, in the length direction of the connecting rod 30, the connecting rod 30 is provided with a plurality of mounting grooves 31, the plurality of mounting grooves 31 are arranged at intervals in the length direction of the connecting rod 30, each air deflector 20 is provided with a clamping shaft 22, the clamping shaft 22 is clamped in the mounting groove 31, the plurality of air deflectors 20 and the plurality of mounting grooves 31 are arranged in a one-to-one correspondence, and when one air deflector 20 of the plurality of air deflectors 20 rotates relative to the volute body 10, the plurality of air deflectors 20 can rotate together under the action of the connecting rod 30.

In a further embodiment of the present invention, the clamping shaft 22 is disposed at the middle of the air deflector 20, when the connecting rod 30 is coupled and matched with the plurality of air deflectors 20, the connecting rod 30 is disposed at the middle of the plurality of air deflectors 20, and the extending direction of the connecting rod 30 is the same as the arrangement direction of the plurality of air deflectors 20 in the volute body 10.

Specifically, the plurality of air deflectors 20 are respectively connected with the mounting groove 31 in a clamping manner through the clamping shaft 22, the plurality of air deflectors 20 are rotatably connected with the volute body 10, and when the position of the connecting rod 30 relative to the volute body 10 changes, the connecting rod 30 can drive the plurality of air deflectors 20 to rotate relative to the volute body 10, so that the plurality of air deflectors 20 can rotate synchronously.
