The rotation of the driving wheel can squeeze the cleaning seat. Since the cleaning seat is installed inside the subway car through the hydraulic rod, the connecting rod and the connecting seat, and the connecting rod can move inside the connecting seat, the cleaning seat can move back and forth through the cyclic squeezing of the two driving wheels. At this time, the cleaning brush contacts the pedal and the anti-skid groove.

[0020] Secondly: the present invention is provided with a cleaning mechanism. When the dust and impurities on the surface of the pedal and the anti-skid groove are cleaned, the air pump can be started.

The suction inside the cleaning tube can be transmitted to the inside of the cleaning seat through the movable tube and the collecting tube. The cleaning seat can then suck the dust and impurities cleaned on the surface of the pedal and the anti-skid groove into the inside of the cleaning seat through the collecting port, and then be sucked into the inside of the movable tube and the cleaning tube by the collecting tube, thereby improving the cleaning effect of the pedal and the anti-skid groove while also collecting the dust and impurities cleaned.

[0021] Third: In the present invention, through the setting of the fan blades, when the outside air moves inside the air inlet and the exhaust port, the fan blades will rotate, thereby driving the rotating shaft to rotate, and the rotating shaft can drive the cleaning brush to rotate. The rotation of the cleaning brush can clean the surface of the filter element, thereby achieving the effect of automatically cleaning the filter element during driving, avoiding the situation where the filter element is blocked by dust and the collection effect is deteriorated.

[0022] Fourthly: in the present invention, through the setting of the air storage pipe, when the pedal is extended toward the outside, the pedal can drive the piston plate to move inside the air storage pipe through the push rod. At this time, the outside air can be sucked into the air storage pipe through the second air inlet pipe, and then when the pedal is retracted toward the inner groove, the pedal can drive the piston plate to move inside the air storage pipe through the push rod. At this time, the air inside the air storage pipe will be squeezed into the second air outlet pipe, and then can enter the interior of the cleaning seat through the air supply hole, and then can be discharged from the interior of the cleaning seat through the collecting port. At this time, the interior of the collecting port can be cleaned to avoid the situation where the interior of the collecting port is blocked by dust and impurities. Subsequently, the cleaning seat can move downward to clean the pedal and the anti-slip groove, thereby improving the cleaning effect next time. BRIEF DESCRIPTION OF THE DRAWINGS

The cleaning seat 9 drives the cleaning brush 10 to move back and forth to clean the surface of the pedal 4 and the anti-skid groove 5, thereby improving the cleaning effect of the pedal 4 and the anti-skid groove 5 and avoiding the decrease of the anti-skid effect of the anti-skid groove 5.

[0044] A cleaning mechanism is also provided. When the dust and impurities on the surface of the pedal 4 and the anti-skid groove 5 are cleaned, the air pump 17 can be started. The air pump 17 generates suction inside the cleaning tube 19 through the pneumatic tube 18. The suction inside the cleaning tube 19 can be transmitted to the inside of the cleaning seat 9 through the movable tube 20 and the collecting tube 21. The cleaning seat 9 can then suck the dust and impurities cleaned on the surface of the pedal 4 and the anti-skid groove 5 into the inside of the cleaning seat 9 through the collecting port 22, and then be sucked into the inside of the movable tube 20 and the cleaning tube 19 by the collecting tube 21. Therefore, while improving the cleaning effect of the pedal 4 and the anti-skid groove 5, the dust and impurities cleaned can also be collected.

[0045] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
