The invention discloses an odor-resistant floor drain which comprises an upper shell, a lower shell, an S-shaped elbow and a funnel, wherein the lower shell is connected to the downside of the upper shell, the S-shaped elbow is positioned inside the lower shell and is fixedly connected with the inner side wall of the lower shell by virtue of a connecting column, the upper end of the S-shaped elbow is communicated with the upper shell by virtue of the funnel, a circle of annular bulges is formed on the pipe wall in the middle of the S-shaped elbow, a circular baffle sheet is arranged above the annular bulges, one side of the circular baffle sheet is fixed on the side wall of the S-shaped elbow by virtue of a rotating shaft, the diameter of the circular baffle sheet is smaller than the inner diameter of the S-shaped elbow in which the circular baffle sheet is located, and greater than the inner diameter of the annular bulges, one layer of sealing gasket is arranged at the bottom of the circular baffle sheet, and drain holes are formed in the upper surface of the upper shell. The rotatable circular baffle sheet is arranged inside the S-shaped elbow, and the circular baffle sheet is matched with the annular bulge, so that the odor-resistant floor drain can play a role of resisting odor when water inside the floor drain is less; the annular bulges are in indirect contact with the circular baffle sheet by virtue of the sealing gasket, so that the odor resistance effect is improved.
