Air deflector assembly and air conditioner

The utility model provides an air deflector assembly and an air conditioner, the air deflector assembly comprises an air deflector body and a switching piece, the air deflector body comprises a plurality of sub-plates, each sub-plate is provided with a rotating shaft part, the sub-plates are sequentially arranged in the axial direction of the rotating shaft parts, and the rotating shaft parts of any two adjacent sub-plates have a connection state and a disconnection state. When the two adjacent rotating shaft parts are in a connected state, the two corresponding adjacent sub-plates are relatively fixed at least in the circumferential direction of the rotating shaft parts; when the two adjacent rotating shaft parts are in a disconnected state, the two corresponding adjacent sub-plates can rotate relatively; and the switching piece is used for controlling any two adjacent rotating shaft parts to be switched between a connection state and a disconnection state. The air guide plate assembly can solve the technica
