[0009] Furthermore, the aperture of the first filter hole is larger than the aperture of the second filter hole.

[0010] The advantages of the present invention are:

[0011] The utility model prevents the sleeve and the filter from slipping out of the drain hole, prevents mud and sand from entering the drain sleeve, avoids pipe blockage, the gravel plays the role of primary filtration, the filter plays the role of secondary filtration and tertiary filtration, and the clamp is stuck in the "gap between the filter and the water vortex bottom plate" to hold the filter upward so that it will not slip out of the drain hole.
