Therefore, when the rain falls on the driveway (1) and sidewalk (4), the rainwater gathers at the edge of the road, passes through the grating (3), flows down to the rain gutter (2), and then flows through the discharge pipe (7) to the sewer pipe (6). .

By the way, the sewage pipe (6) is not only rainwater, but also because various living sewage, such as discharged water in the kitchen and toilet are joined inside the sewage pipe (6) is always full of odor. In particular, when discharging domestic sewage in a large building such as a hotel, the inside of the sewage pipe 6 is more filled with odor. These odors are flowed back to the outside through the discharge pipe (7), rain gutters (2), because the odor of living sewage is disgustingly disgusting, there was a problem that gives a very unpleasant feeling to passers-by and residents.

Conventionally, as a device for removing the backflow of the odor has been proposed to open and close when the rain water flows into the rain gutter (2) and closed when it does not flow, such a device is a branch in the open portion when rain water flows down In the case of foreign objects such as stones, even if it does not rain, there is a problem that the malfunction of the open portion is not closed and the odor is often reversed, which is not actually used.

The present invention has been devised to solve the problem of the odor blocking device of the conventional road rain gutter, as well as completely block the phenomenon of odor of living sewage flowing into the sewer pipe back to the rain gutter, the malfunction does not occur in any situation. The object of the present invention is to provide a odor blocking device for rain gutters.
