Long-term filtering of the water absorption sponge 609 will cause the water absorption sponge 609 to be saturated with water. When the filter plate one 607 moves, it will squeeze the water absorption sponge 609 to squeeze out the water in the water absorption sponge 609, and the water will be discharged from the dustproof filter hole 610 along the slope of the circular box 2, avoiding the influence of water saturation on the filtering effect of the water absorption sponge 609, causing water to enter the installation box 509 to cause damage to the electronic elements and the occurrence of line short circuit;
