[0034] The working principle and beneficial effects of the above technical solution are: When in use, the fan 1 6 and the exhaust fan 8 are in a normally open state during the normal operation of the elevator, and fresh air is drawn in from the top of the outer body 1, passes through the inner body 2, and then discharged from the exhaust fan 8 through the floor 3, so as to form a top-down circulation of air. The fan 2 7 and the warm air heater 5-1 of the present invention can be started manually, or a humidity sensor can be set in the inner body 2, and the humidity sensor detects the air humidity in real time, and transmits the detection data to the controller of the elevator. When the humidity reaches a preset value, the controller sends a control instruction to control the fan 2 7 and the warm air heater 5-1 to start. When the fan 2 7 is started, the air outside the outer body 1 is drawn into the warm air heater 5-1 for heating and then blown to the space between the outer body 1 and the inner body 2, and blown out from the first vent 5-2 to the floor 3, accelerating the evaporation of the accumulated water on the floor 3. At the same time, the hot air also increases the temperature of the surface of the inner body 2, thereby reducing the heat release and liquefaction of the warm and humid air when it encounters the lower temperature of the inner body 2 to form water droplets. In winter, the hot air drying mechanism 5 can also be used as a heating device. In this embodiment, a temperature sensor is provided on the outside of the inner compartment 2, and the temperature sensor is connected to the controller. Based on the detected temperature data, the operation of the warm air heater 5-1 is controlled to keep the air temperature between the outer compartment 1 and the inner compartment 2 at about 26 degrees. When the elevator is stationary, the controller enters a short maintenance mode, that is, the controller controls the drive motor 2 and the drive motor 3 to rotate, open the cover plate 1 3-4 and the cover plate 2 3-5, and then the controller controls the telescopic rod 2 3-7 to extend to lift the wiper 4-1, and then the controller controls the telescopic rod 1 4-22 to extend and insert into the jack 4-14, and then the controller controls the drive motor 1 4-29 to start, and perform forward and reverse alternating work, so that the wiper 4-1 moves back and forth on the floor 3, and under the push of the cleaning brush 4-13, the accumulated water and debris on the floor 3 are pushed into the three collection boxes 3-6. After cleaning, the controller reversely controls each component to reset. During maintenance, it is only necessary to open the cover plate 1 3-4 and the cover plate 2 3-5, take out the collection box 3-6 therein, remove the wiper plate 4-1, disconnect the connection line between the telescopic rod 2 3-7 and the controller, and then take out the collection box 3-6, and then clean the collection box 3-6.

[0035] Compared with the prior art, the present invention can quickly clean the floor of the car through the arrangement of the hot air drying mechanism 5 and the cleaning mechanism 4, and at the same time prevent the condensation of water droplets and reduce the generation of accumulated water, making the car clean, tidy and comfortable. The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
