PURPOSE: A drain trap for blocking odor and backflow is provided to improve a function for blocking odor by firmly maintaining the sealed state of a drain port, and smoothly drain water by forming the diameter of a flow path to be uniform. CONSTITUTION: A drain trap(100) for blocking odor and backflow includes a main body(4), a blocking plate, an elastic restoring bar(7), a spread magnet, and a sealing magnet. The elastic restoring bar is installed at the blocking plate. The elastic restoring bar applies an elastic force to the blocking plate so that the blocking plate folded by water pressure is horizontally spread. The spread magnets having same poles one another spread the blocking plate with repulsive forces. The sealing magnets have different poles one another. When the water pressure is released, the blocking plate is horizontally spread by the elastic restoring bar, the spread magnet, and the sealing magnet so that a drain port is sealed. |
