[0039] Furthermore, the second pushing mechanism includes a third fixed ring 901 fixedly mounted on the side wall of the rotating rod 11, and a plurality of array-arranged convex strips 902 are fixedly connected to the circumferential side of the third fixed ring 901, one end of the movable cover 701 is fixedly connected to the first pushing rod 903, and one end of the first pushing rod 903 slides on the side wall of the convex strip 902, when the convex strip 902 abuts against one end of the first pushing rod 903, the movable cover 701 and the rubber rod 702 are pushed to move, and at the same time, the third spring 804 is compressed, and when the convex strip 902 passes over the end of the first pushing rod 903, the movable cover 701 and the rubber rod 702 can be reset under the action of the third spring 804.

[0040] Furthermore, the dust collection mechanism includes a third support plate 1001 fixedly connected to the upper side wall of the protective cover 16, and the upper end of the third support plate 1001 is fixedly connected to a working pipe 1002, the side wall of the working pipe 1002 is fixedly connected to an exhaust pipe 1005, and a first one-way valve 1006 is arranged in the exhaust pipe 1005, and the conduction direction of the first one-way valve 1006 is from the fan-shaped cover 401 and the movable cover 701 to the working pipe 1002, a first hose 1007 is fixedly connected between the exhaust pipe 1005 and the fan-shaped cover 401, and a second hose 1008 is fixedly connected between the exhaust pipe 1005 and the movable cover 701, and the side wall of the working pipe 1002 is fixedly connected to the exhaust pipe 1005. A collecting pipe 1003 is connected, and a second one-way valve 1004 is arranged in the collecting pipe 1003. The collecting pipe 1003 can be connected to an external dust removal device for easy collection. The conduction direction of the second one-way valve 1004 is from the working pipe 1002 to the outside. A piston 1009 is slidably connected in the working pipe 1002, and one end of the piston 1009 is connected to one end of the working pipe 1002 through a compression spring 1011. One end of the piston 1009 is fixedly connected to a moving rod 1010, and the other end of the moving rod 1010 slides on the side wall of the convex strip 902. A first dust suction hole 1012 is opened at the lower end of the knocking rod 402, and the lower end of the rubber rod 702 A second dust suction hole 1013 is provided. When the filter screen 14 rotates to the protective cover 16, when the convex strip 902 abuts against one end of the moving rod 1010, the piston 1009 is pushed to move. At the same time, the compression spring 1011 is stretched. When the convex strip 902 passes over the moving rod 1010, the piston 1009 can be reset under the action of the compression spring 1011, so that the piston 1009 can reciprocate in the working tube 1002. When the piston 1009 moves away from the exhaust pipe 1005, a negative pressure is generated in the working tube 1002. At the same time, the first one-way valve 1006 is opened and the second one-way valve 1004 is closed. At this time, the first one-way valve 1006 is opened and the second one-way valve 1004 is closed. Air is sucked through the dust suction hole 1012 and the second dust suction hole 1013, and then enters the working tube 1002 through the first hose 1007 and the second hose 1008 through the exhaust pipe 1005. When the piston 1009 moves toward the exhaust pipe 1005, the air in the working tube 1002 is squeezed. At the same time, the first one-way valve 1006 is closed and the second one-way valve 1004 is opened, thereby squeezing the air through the collecting pipe 1003. This reciprocating process can absorb impurities during vibration cleaning and cleaning, and collect them uniformly through the collecting pipe 1003, thereby facilitating the collection of impurities and preventing them from floating, which is more environmentally friendly and healthy.

[0041] Working principle: By setting up multiple filters 14 for use in rotation, the filtering efficiency and effect of the filter 14 can be improved, the internal temperature thereof is prevented from being too high to affect its service life, and the heat dissipation effect of the switch cabinet body 1 is ensured, thereby ensuring its service life;

[0042] When the filter 14 needs to be rotated, the motor 18 is started, and the rotation of the motor 18 drives the rotation of the rotating rod 11 and the rotating disk 12, so that the cleaned filter 14 in the protective cover 16 is rotated to the upper end of the heat dissipation fan 101, and the filter 14 with more impurities is rotated into the protective cover 16. During the rotation process, the rotation of the rotating rod 11 drives the rotation of the second fixing ring 601 and the conical block 602. When the conical block 602 abuts against the sliding plate 503, the sliding plate 503 and the fan-shaped cover 401 are pushed upward, and at the same time When the second spring 504 is compressed, when the sliding plate 503 passes over the conical block 602, the sliding plate 503 and the fan-shaped cover 401 can move downward under the action of the second spring 504, so that the fan-shaped cover 401 can move back and forth up and down, and the movement of the fan-shaped cover 401 drives the synchronous movement of the knocking rod 402, so that the filter screen 14 can be knocked and vibrated during its rotation, so as to facilitate the vibration cleaning of impurities on its surface, ensure the filtering efficiency and effect, and periodically start the motor 18 to realize the automatic rotation of the filter screen 14;

[0043] At the same time, in the process of the filter screen 14 rotating to the protective cover 16, the rotation of the rotating rod 11 drives the synchronous rotation of the third fixing ring 901. When the convex strip 902 abuts against one end of the first push rod 903, the movable cover 701 and the rubber rod 702 are pushed to move. At the same time, the third spring 804 is compressed. When the convex strip 902 passes over the end of the first push rod 903, the movable cover 701 and the rubber rod 702 can be reset under the action of the third spring 804, so that the rubber rod 702 can reciprocate and clean the surface of the filter screen 14, so that the cleaning effect is better, and the filtering efficiency and effect are guaranteed.

[0044] Furthermore, during the process of the filter screen 14 rotating to the protective cover 16, when the convex strip 902 abuts against one end of the moving rod 1010, the piston 1009 is pushed to move, and at the same time, the compression spring 1011 is stretched. When the convex strip 902 passes over the moving rod 1010, the piston 1009 can be reset under the action of the compression spring 1011, so that the piston 1009 reciprocates in the working tube 1002. When the piston 1009 moves away from the exhaust pipe 1005, negative pressure is generated in the working tube 1002. At the same time, the first one-way valve 1006 is opened and the second one-way valve 1004 is closed. At this time, the dust is sucked through the first suction hole 1006. 12 and the second dust suction hole 1013 are used to suck air, and then enter the working tube 1002 through the first hose 1007 and the second hose 1008 through the exhaust pipe 1005. When the piston 1009 moves toward the exhaust pipe 1005, the air in the working tube 1002 is squeezed. At the same time, the first one-way valve 1006 is closed and the second one-way valve 1004 is opened, so that the air is squeezed out through the collecting pipe 1003. This reciprocating process can absorb impurities during vibration cleaning and cleaning, and collect them uniformly through the collecting pipe 1003, so as to facilitate the collection of impurities and prevent them from floating, which is more environmentally friendly and healthy.
