The present invention relates to an odor blocking pipe formed with elastic materials having a function for discharging drawn sewage by mounted on an inner rim (31) of an expanded seamed pipe (30) with one group of reducer (40) and for blocking odor reversely flowing in a discharge pipe. The present invention is mounted on the inner upper end of the seamed pipe (30) to be closely attached, and a tube pipe (10) connected to a bushing (20) is formed with the elastic materials of a silicone material. An outer pipe (16) and an inner pipe (17) are integrally formed at a lower end (15) of a main body (11), and the outer surface of the inner pipe (17) is in contact with the inner surface of the outer pipe (16). Therefore, the odor blocking pipe is opened and closed according to the inflow of the sewage. |
