The present invention relates to an odor preventer for a drain pipe used by fitting into the drain pipe and, more specifically, to an odor preventer for a drain pipe including a pipe-shaped guide pipe unit installed to cover the inner circumference of the drain pipe to allow waste water discharged through the drain pipe to be received and flow downward and having a predetermined length; a reduce pipe unit having a first supporting plate and a second supporting plate, formed into a pipe shape, connected to an lower part of the guide pipe unit, formed in both sides of the guide pipe unit, and bent and tilted to the center of the guide pipe unit and of which an inner diameter becomes narrower to the lower part to allow the undersides of the first and second supporting plates facing each other to adhere to each other; and an opening and closing pipe unit formed into a pipe shape, extended downward at a predetermined length from the lower part of the reduce pipe unit, bent outward to the lower parts of the first and second supporting plates, and having the inner surfaces adhering to each other. According to the present invention, the inner part of the pipe opened by a pressure of the waste water is elastically restored by the bent surfaces within a short time, thus an effect of closing the lower part of the pipe to prevent an intake of odor is obtained. In addition, first and second opening and closing plates made of a silicon material with a predetermined thickness, not a material such as soft vinyl, in order to increase an adhering force of the lower part of the odor preventer are bent, thereby adhering to each other without being easily torn and obtaining high durability. Accordingly, an effect of using the odor preventer for a long term is obtained. |
