Anti-backflow water pipe
The invention discloses an anti-backflow water pipe. An elastic piece in a pipe body will turn over downwards when impacted by water flow on the upper side to allow water and impurities to pass through; when no water exists on the upper side, the elastic piece is placed horizontally so that peculiar smell in the pipe body can be prevented from being dispersed; when the lower portion is impacted by the water flow, the elastic piece is located below a boss on the upper side in an abutting-against mode to prevent the water from passing so as to effectively prevent the water in the pipe body from flowing out in a backflow mode.
