Deodorizing and anti-backflow floor drain

Abstract

The invention relates to a floor drain which is used for promoting drainage from sinks, pools, washing machines, grounds and urinals towards building pipelines, and in particular to a 'deodorizing andanti-backflow floor drain'. According to the technical scheme, the deodorizing and anti-backflow floor drain mainly comprises a floor drain box, an anti-backflow device and an eaves-shaped waterway deodorizing cover; the deodorizing and anti-backflow floor drain is characterized in that the anti-backflow device is arranged at the bottom of the anti-backflow floor drain box; the anti-backflow device is composed of a water storage pipe which runs the inside and the outside of the box and an anti-backflow spherical floating gate; the water storage pipe in the floor drain box is covered by the eaves-shaped deodorizing cover, so that a deodorizing purpose is achieved; the anti-backflow spherical floating gate is lifted by a water level, which rises, of backflow water in the case that the building pipeline gets blocked, so that a nozzle of the water storage pipe of the floor drain box is blocked, and the water, which rises in the building pipeline, is prevented from flowing back into the floor drain box and then flowing indoors.

Description
