Anti-backflow water pipe
The invention discloses an anti-backflow water pipe. A spring piece in a pipe body is overturned downward when subjected to impact of water flow above the spring piece, so that water and impurities are allowed to pass. When there is no water above the spring piece, the spring piece is horizontally placed, and abnormal smells in the pipe body can be prevented from spreading. When subjected to impact of water flow below the spring piece, the spring piece abuts against the lower portion of a boss above the spring piece to prevent water from passing, and the water in the pipe body is effectively prevented from flowing back and coming out.
