Malodor reflux blocking unit using cardiac valve principle and malodor reflux blocking device including the same
A malodor reflux blocking unit using the cardiac valve principle, includes a space providing portion inserted into the drain pipe through the drain hole and configured to provide a drain space for the drainage, blocking portions which are, in a non-draining state, disposed to face each other and configured to block communication between the drain pipe and the drain space due to a water film phenomenon which occurs due to drainage water being present between the blocking portions, and intermediate portions configured to mediate connection between the blocking portions and the space providing portion.
