发明名称 Drain water-intake cover
摘要 A drain water-intake cover includes a fixed brim, a central convex portion of which is low in height, an upper water-intake opening on the convex portion, side water-intake openings on a side peripheral wall of the convex portion and a plurality of mutually spaced dust stoppers extending over the upper water-intake opening and having different height dimensions. Stumbling over the cover is prevented since the cover is low in height and is not highly protrusive. Rainwater can be drained even when dust or foreign matter such as fallen leaves, vinyl or trash clings to the cover. The cover dries easily even when rainwater remains on the cover.
