Description

A device to prevent a bad smell for drainage hole}

The present invention relates to a device for blocking odor in a drain, and more particularly, it is installed so as to cover the top of a drain formed to be exposed to the ground in a state of communication with an underground sewage pipe, so that rainwater can be easily drained. At the same time, it relates to an odor blocking device for a drain that can very effectively block odor generated inside a sewage pipe and a drain from rising to the ground.

In general, at the edge of the road between the road and the sidewalk or the edge of the parking lot of an industrial building or apartment complex, in order to quickly drain rainwater or living water discarded after use, a drain connected to an underground sewer pipe (排水口) is formed.

A lattice net is installed in such a drain hole to filter foreign substances contained in rainwater or domestic water discarded after use. Since the lattice net has a relatively wide interval between the grids, small foreign substances such as cigarette butts are not properly filtered out. There is a problem that it flows into the drain and causes the sewage pipe to be clogged.

In addition, since the conventional drain is not equipped with a separate device to block odor, when the outside temperature rises, such as in summer, the extreme odor generated from the inside of the sewer pipe or drain rises to the ground, causing severe discomfort. There is a serious problem with
