An air-entraining port cover. The air-entraining port cover is arranged at an air-entraining port of an airplane body (30) and comprises a fixing frame (10) and an air filtering member (20). An annular groove (11) is formed in an inner side frame body of the fixing frame (10), the air filtering member (20) is fixedly installed in the annular groove (11), and the fixing frame (10) is fixedly arranged at the air-entraining port. The air-entraining port cover further comprises at least one first supporting beam (12) fixed to the fixing frame (10) in a crossing mode and located on the side of the air filtering member (20) close to the air-entraining port, so as to support the air filtering member and protect the air filtering member from damage.
