[0029] The device main body 1 is provided with a mounting frame 20 on the front surface, the mounting frame 20 is internally provided with four sealing plates 25, the sealing plates 25 are uniformly distributed in the mounting frame 20, the sealing plates 25 are provided with grooves 28, the grooves 28 are internally provided with round sticks 26, the round sticks 26 are provided with collars 31, the collars 31 are internally provided with balls 33, the collars 31 can slide on the round sticks 26, the collars 31 are provided with connecting blocks 30, the connecting blocks 30 are provided with cleaning strips 27, the cleaning strips 27 are provided with fluorescent strips 29 on the upper surface, the fluorescent strips 29 have two pieces and are located at both ends of the cleaning strips 27 respectively, the cleaning strips 27 are provided with cleaning brushes 32 on the lower surface, and the cleaning brushes 32 can automatically clean the dust on the sealing plates 25 during daily use, can clean the snow accumulated on the sealing plates 25 in snowy weather, avoid the snow from being condensed into ice, cause the sealing plates 25 to be not smooth in opening and closing, and thus improve the sealing property of the device;

[0030] The filter frame 8 and the device body 1 form a to-be-discharged cavity 34, which can temporarily stop the exhaust by closing the sealing plate 25 when the vehicle speed changes or is about to enter the tunnel, temporarily store the exhaust in the to-be-discharged cavity 34, and then open the sealing plate 25 to discharge the exhaust after the vehicle speed stabilizes, thereby improving the sealing performance of the device and minimizing the ear pain and tinnitus caused by air pressure waves to passengers in the vehicle compartment.

[0031] Further, the first connecting rod 21 is installed on one side surface of the mounting frame 20, the first connecting rod 21 is connected with the sealing plate 25 through a connecting shaft, there are four first connecting rods 21 corresponding to the sealing plate 25 respectively, and the second connecting rod 22 is installed on the first connecting rod 21.

[0037] Considering that the environment changes (such as speed change, meeting or entering the tunnel, etc.) during the train running, the air around the train will change sharply, forming an air pressure wave, which will enter the car through the exhaust device. Air pressure wave will cause passengers in the car to have tinnitus, ear pain and other injuries, so a waiting discharge cavity 34 is formed between the filter frame 8 and the equipment main body 1. Before the speed changes or before entering the tunnel, the sealing plate 25 is closed by the controller 5, temporarily stopping the exhaust, and the exhaust gas is temporarily stored in the waiting discharge cavity 34. After the speed is stable, open the sealing plate 25 to discharge the exhaust gas. Improve the sealing of the device, while minimizing the tinnitus and ear pain caused by air pressure waves to passengers inside the car. Considering that in the process of train running, when it snows, snowflakes will fall on the inner surface of the sealing plate 25. After freezing into ice, it will hinder the opening and closing of the sealing plate 25, causing poor sealing effect. Therefore, a cleaning strip 27 is provided. The ball 33 drives the cleaning strip 27 to clean the inner surface of the sealing plate 25. No external power supply is required. Through the acceleration and deceleration of the train itself, the inertia drives the sleeve ring 31 to move forward and backward, thereby achieving the cleaning of the inner side of the sealing plate 25. At the same time, it can prevent the snow from blocking the air outlet in snowy weather. The fluorescent strip 29 is also provided on the cleaning strip 27, which can help the staff quickly find the exhaust device after the train enters the station, so as to clean and replace it, thereby ensuring the exhaust efficiency and improving the work efficiency.
