The main body of the one-way valve is a valve seat 3, and a valve plate 4 is arranged inside the valve seat 3. Under normal circumstances where drainage is not completed, the valve plate 4 is pressed against the non-return surface 32 of the valve seat 3 by gravity, so that the pipe 31 on one side of the valve seat 3 is closed, preventing the odor in the drainage pipe or sewage pipe connected to the same-floor drainer from floating out from the water channel 22 of the water accumulation tray;
