Optionally, the air baffle 33 moves in synchronism with the air deflector 32.

Thus, the choke plate 33 moves synchronously with the wind deflector 32, specifically, when the wind deflector 32 opens the air supply port 203, the choke plate 33 opens the return air passage 206; when the air door 21 is closed, the air blocking plate 33 is closed, and the air backflow phenomenon in the first door body 20 can be effectively avoided by controlling the air blocking plate 33 and the air blocking plate 32 to synchronously move.

Optionally, a drive motor is drivingly connected to both the choke plate 33 and the wind deflector 32 to drive movement of the choke plate 33 and the wind deflector 32. Thus, by providing the motor to drive the choke plate 33 and the wind deflector 32, the choke plate 33 and the wind deflector 32 can be automatically moved.
