Deodorant floor drain

The utility model discloses a deodorization floor drain, comprising a floor drain water storage base provided with a water outlet at side edge; a floor drain cover covering the floor drain water storage base, which is provided with a water inlet; a floating ball in the floor drain water storage base for lifting under the floating force of the water in the floor drain water storage base and blocking the water inlet of the floor drain cover. When the discharge water enters into the floor drain water storage base, the floating ball in the inner chamber flits up and seals the water inlet of the floor drain cover, to prevent the odor of underground sewage from entering into room, and when there is water enter again, the floating ball will be pressed by pressure, to make discharge water successfully enter into the floor drain and flow out; when the underground water level is over high, the floating ball will be pressed under internal pressure to close the water inlet of the floor drain, thereby preventing sewage from entering into room. The deodorization floor drain has simple and effective structure, is suitable for discharging water, and resolves the problem that traditional floor drain will disperse the odor of gully drain and sewage will enter into room.
