[0028] Working principle: Under the action of the filter 6, the air entering the control box 2 can be filtered, and the dust and other impurities in the air can be filtered out before entering the control box 2 through the heat dissipation port 3, thereby improving the cleanliness of the space in the control box 2, and preventing external dust from adhering to the electrical components in the control box 2. After the filter 6 has been used for a period of time, by pulling the plug block 11, the movable plug block 11 can drive the T-block 10 to move horizontally on the limit rod 9, and the movable T-block 10 will squeeze the spring 17 on the inner wall of the fixed block 8, so that the spring 17 is in a taut state. When the movable plug block 11 is separated from the fixed groove 16 and no longer contacts the positioning block 4 After that, the connection ring 5 and the filter screen 6 can be released, and then the connection ring 5, the filter screen 6, and the connection block 7 can be removed from the control box 2. At the same time, when the moved plug-in block 11 does not affect the flipping of the movable block 13, the movable block 13 is flipped, so that the movable block 13 and the limiting groove 15 are flipped with the connecting rod 12 as the central axis, and under the action of the anti-detachment block 14, the movable block 13 can be prevented from being separated from the connecting rod 12. When the flipped limiting groove 15 corresponds to the plug-in block 11, the movable block 13 can be located on one side of the fixed groove 16 at the same time, and then the pulled plug-in block 11 is released, so that the spring 17 is no longer restricted by the tension and rebounds, so that the rebound spring 17 drives the T-block 10 and the plug-in block 11 to rebound. The block 11 is reset and when the movable plug-in block 11 is inserted into the limiting groove 15, the movable block 13 is restricted so that the movable block 13 will not flip over again. At the same time, under the action of the movable block 13, the plug-in block 11 can be prevented from being inserted into the fixing groove 16 again, so as to facilitate the subsequent connection between the control box 2 and the filter screen 6. Then, the connecting block 7 is pulled to remove the connecting ring 5, the filter screen 6 and the connecting block 7 from the positioning block 4. After the removed filter screen 6 is cleaned, the connecting ring 5 is inserted into the positioning groove 18, and the connecting block 7 is brought into contact with the control box 2, so as to complete the preliminary connection between the control box 2 and the filter screen 6. At the same time, the plug-in block 11 can correspond to the fixing groove 16, and then Pull the plug block 11 to move the T-block 10 and the plug block 11 while keeping the spring 17 in a taut state. When the movable plug block 11 is disengaged from the limiting groove 15, the restriction on the movable block 13 can be released, and then the movable block 13 is flipped back to reset the movable block 13 and no longer block the fixed groove 16. Then the pulled plug block 11 is released to make the spring 17 rebound without being restricted by the tension, so that the rebound spring 17 drives the T-block 10 and the plug block 11 to move. When the movable plug block 11 is inserted into the fixed groove 16, the connection ring 5, the filter screen 6 and the connection block 7 are fixed, so that the filter screen 6 can always be located on one side of the heat dissipation port 3 without movement.
