The invention provides an air-conditioner fresh air and returned air control damper and a tuyere assembly. The air-conditioner fresh air and returned air control damper comprises a main damper body and an auxiliary damper body, wherein the main damper body is hinged to the tuyere assembly, an auxiliary damper body tuyere is arranged on the main damper body, and an internal circulation air inlet and an external circulation air inlet can be sealed or opened by the main damper body; the auxiliary damper body is hinged to the main damper body to be used for sealing or opening the auxiliary damper body tuyere. Due to the fact that the auxiliary damper body tuyere is arranged on the main damper body and closing or opening of the auxiliary damper body tuyere is controlled by the auxiliary damper body, part of internal circulation airflow can still be mixed into the tuyere during external circulation of an automobile air-conditioner or external circulation airflow can be mixed into the tuyere during internal circulation of the automobile air-conditioner, internal circulation airflow and external circulation airflow blending is achieved, the load of the air-conditioner is effectively reduced, and the quality of air inside a cabin can be adjusted.
