The present invention relates to a drain trap; More specifically, it relates to a “drain trap with odor backflow prevention function” that is installed on the floor of a toilet (bathroom) or veranda to guide the water out through the drain pipe and prevent internal odors from entering the drain pipe.

In general, not only multi-family houses, apartment houses, but also multi-family houses, as well as general homes, a water collecting tank is installed to collect and treat various types of sewage. have. In such a drain pipe, a large amount of water and filth, such as toilets and bathtubs, go down together, and odors (odors) can flow back. A drain trap is installed.

As shown in FIG. 1, the conventional drainage trap includes a drain trap body 1 installed directly above the drain pipe P and having a coupling hole 2 in the center, and a barrel of the drain trap body 1 . The drain container (3) which is detachably installed while extending downwardly to the coupling port (2) and is filled with water at a certain height at the bottom (3) and the drain trap body (1) extend downward to the coupling hole (2) of the main body (1) It is installed to be detachably installed and the lower end is installed to cover the drain pipe (4) that is received spaced apart in the internal space of the residual drain tank (3), and the upper part of the drain trap body (1), and the drain hole (5a) is provided throughout.
