An elevator car protection device comprises an anti-triggering air supply mechanism (100), a lifting appliance assembly (200) and an elevator car (300), the anti-triggering air supply mechanism (100) comprises a pressure container (106), a movable plunger (107) and an electromagnet (110), the movable plunger (107) is slidably connected with the pressure container (106), the top end of the movable plunger (107) is fixedly connected with a magnetic end head (108), the electromagnet (110) is arranged over the magnetic end head (108), and the lifting appliance assembly (200) is fixedly connected with the pressure container (106). The electromagnet (110) is in magnetic connection with the magnetic end (108), the electromagnet (110) is electrically connected with a power supply circuit of the elevator, power failure of the electromagnet serves as a triggering condition for reversely triggering the air supply mechanism, opening of the pressure container is controlled through gravity of the movable plunger, extra power and control sources are not needed, and the safety of the elevator is improved. The device can be used for temporary oxygen supply of the elevator car under emergency conditions such as power failure.
