The circumferential surface of the screw rod 5 and the U-shaped plate 7 slide through the inner and outer walls of the equipment frame 1. A slide groove 102 is opened on the top of the equipment frame 1. The vibration plate 8 is slidably installed in the slide groove 102. An exhaust port 701 is opened on the outer wall of the U-shaped plate 7. The filter plate 9 is fixedly installed in the exhaust port 701. The vibration plate 8 moves and collides with the filter plate 9 to generate vibration. Some dust and dirt are cleaned by vibrating the surface of the filter plate 9, thereby achieving protection of the equipment. Failure to clean for a long time will lead to accumulation of dust and dirt, which may damage the equipment and reduce the service life of the equipment.

[0020] The moving block 6 is fixedly connected to the U-shaped plate 7, and the vibration plate 8 is fixedly connected to the end of the U-shaped plate 7 away from the fan 4. The movement of the moving block 6 drives the U-shaped plate 7 to move, and the movement of the U-shaped plate 7 drives the exhaust port 701 to move, thereby achieving the exhaust function. The movement of the U-shaped plate 7 drives the vibration plate 8 to move.

[0029] When the filter plate 21 moves upward, it drives the scraper 20 to move. The scraper 20 moves upward, drives the moving rod 19 to move upward. The moving rod 19 moves upward and moves along with the inside of the slide groove 3 105. At the same time, the scraper 20 moves to scrape the surface of the filter plate 213, thereby cleaning the surface of the filter plate 213 to prevent excessive impurities on the surface of the filter plate 21 from affecting the filtering effect of the filter plate 21 and preventing equipment damage and increasing subsequent maintenance costs. When the scraper 20 moves to clean the filter plate 21, the impurities are cleaned to the side close to the baffle 22. When too much impurities accumulate, the baffle 22 will be squeezed to open the baffle 22 to discharge impurities and garbage. When there are no impurities, it will be reset through the torsion spring on the rotating rod 21, thereby cleaning the impurities and preventing excessive accumulation of impurities and dirt on the filter plate 21, which will reduce the filtering effect of the filter plate 21 and cause equipment damage, thereby reducing the service life of the equipment.
