Safety protection elevator car

The invention discloses a safety protection elevator car. The safety protection elevator car comprises a car body. The car body is internally provided with an LED illuminating light, ventilating devices and a handrail. Each ventilating device comprises a ventilating pipe, a fan, a filtering net and an air guiding plate. The bottom of the car body is provided with a first buffer spring and a firstsafety air bag. A second safety air bag and an acceleration sensor are mounted on the side wall of the car body. A transverse plate is mounted on the bottom side of the interior of the car body. A dust falling hole is formed in the transverse plate. A cavity is formed between the transverse plate and the low wall of the car body. The cavity is internally provided with a plurality of second buffersprings. A dust collector is further arranged at the lower end of the left side of the car body. The right end of the dust collector is provided with a dust sucking opening. The dust sucking opening communicates with the cavity. The safety protection elevator car is simple and reasonable in structure and convenient to use, dust is removed timely from a source, the ventilating devices are matched with a dust removing device, the dust removing effect is good, the user experience is ensured, the ventilating devices purify air, and the air quality in the car is improved; and the security experience of a user is ensured through multi-level buffering.
