The elevator car comprises an elevator control system, a car ceiling and a traditional fan, and the traditional fan is installed on the car ceiling and connected with the elevator control system; and the traditional fan works on the condition that an elevator operates normally, and when a fire disaster occurs, the traditional fan stops working under the control of the elevator control system. The elevator car with the fire-fighting function further comprises an air interchanger which is installed on the car ceiling and connected with the elevator control system, the air interchanger does not work on the condition that the elevator operates normally, when the fire disaster occurs, the air interchanger starts working under the control of the elevator control system, air in a hoistway is sucked into the car, and the traditional fan serves as an air outlet channel to exhaust air, containing a large amount of particulate matter, in the car. Due to the fact that air exchanging and filtering functions are adopted, the quality of the air in the car can be improved, and firefighters can conduct rescue more conveniently and safely.
