Meanwhile, when a user uses water for a reason such as bathing, the used water flows through the bathroom floor to the odor backflow prevention device 20 via the drain trap pipe 10.

The sewage flowing into the odor backflow prevention device 20 presses the three elastic valves 21a constituting the lower end 21 of the odor backflow prevention device 20 by its own weight, and the three elastic valves 21a are pressed By being elastically deformed and widened due to sewage, it guides the sewage to be drained, and then, if there is no inflow of sewage, the three elastic valves (21a) are elastically restored to block the drain so that the odor rising from the drain is directed toward the drain trap pipe (10). It prevents leakage again.

Despite these advantages, the conventional drainage trap has the following problems.

Referring to FIG. 4, the conventional drainage trap uses a thin film made of rubber that is easy to elastically restore and elastically transform the three elastic pieces 21a constituting the lower end 21 of the odor backflow prevention device 20, By opening due to the decrease in elastic force due to repeated pressurization of the flowing sewage, a gap (G) is generated, which causes a problem in that odor flows out through the gap (G).

On the other hand, this problem can reduce the decrease in elasticity due to repeated pressurization of the flowing sewage when the three elastic valves 21a are applied to the drain trap pipe 10 in a multiple structure such as a double structure or a triple structure, but the structure Due to its characteristics, only a single structure is available at the lower end 21 of the odor backflow prevention device 20, so the need to improve this has emerged.

5 to 9, the odor blocking drainage trap using elastic force of the present invention is largely composed of a body 100, a shaft fixing part 200, a fitting rod 300, and an internal odor prevention film 400.

First, the body 100 is one in which sewage, which is the water used by the user for the same reason as bathing, flows, and has a tubular shape in which the seating table 110 extends and protrudes along the upper end so as to span the drain, and is similar to a cylindrical body, a square or a pentagon. A tubular body of the same polygonal body may be applied and used, and preferably a cylindrical body may be used.

On the other hand, the diameter of the drain hole where the body 100 is disposed is not standardized and may have a different diameter for each place of use. Thus, the mounting hole 800 may be provided so that the body 100 of the present invention can be mounted regardless of the different diameters of the drain hole.

In this way, the provided mounting hole 800 has a through-type entrance hole 811 at the center, a support plate 810 that spans the drain near the edge, and a vertical surface along the inner surface of the support plate 810 forming the entrance hole 811.

And at the lower end of the fitting bar 300, at least two lower clamping rods 350 and lower straddling protrusions 351 are integrally formed, and through the shaft hole 501 of the lower odor prevention unit 500, the above-mentioned fixation fixed in the same way as

Through this, due to the elastic force of the spring 330 disposed between the fixing plate 320 and the seating space 230, the spring 330 pushes the fixing plate 320 upward, so that the lower odor prevention part 500 is removed from the body. By being in close contact with the lower surface of (100), even if a gap occurs due to deformation of the internal odor prevention film 400, it provides an advantage of blocking odor rising from the sewer.

On the other hand, in order to improve the adhesion performance between the lower odor prevention unit 500 and the body 100, a contact ring body 700 bound along the outer edge of the lower odor prevention unit 500 is provided, and the body 100 The lower surface may be provided to be in contact with the contact ring body 700.
