BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wastewater trap for preventing odor backflow,

More particularly, the present invention relates to a drain trap for preventing odor backflow, and more particularly, to a drain trap for preventing odor from flowing backward, more specifically, by attaching one end and another end of an elastic member having elasticity to a lower portion of a pair of shutoff plates, The end portion of the blocking plate can be brought into contact with the inner side wall of the sleeve tube in accordance with the inward restoring action of the elastic member after the drainage of the sewage is finished so that the odor introduced from the sewage pipe can be completely blocked One drainage trap.

Generally, sewage pipes are installed on the floor of the space that needs water supply and drainage in the building. Especially, the entrance of sewage pipes on the bathroom floor where water (water, tap water, etc.) In addition, it prevents the clogging of sewers by filtering out foreign matter such as hair and various debris mixed with domestic sewage (hereinafter referred to as "domestic sewage") and the harmful sewage gas (odor) generated in sewage main and house drain pipes And drainage traps that prevent backflow and insects from entering the room.

Korean Patent Registration No. 10-1147044 discloses a drain trap which is lifted by buoyancy of water remaining in a drain hole and is attached by a magnetic force to completely block odors entering the room.

According to the prior art, sewage used in a bathroom or a toilet is passed through a cover of a drain trap main body and flows into a drain port, and then filled in a water level holding port. When the sewage is continuously introduced, the blocking plate is separated from the drain port and moved downward When the sewage flow into the drainage port is stopped, some of the sewage is filled in the water level maintenance port. At this time, the blocking plate is raised by the buoyant force, so that the magnetic substance on the upper surface of the isolation plate (Or magnetic body) provided on the bottom of the drain hole, so that it is possible to block the influx of the odor such as the offensive odor coming from the bottom (outlet) of the drain hole.

However, in the prior art, when foreign substances such as hair and various debris, which are mixed with sewage and drained together, are continuously deposited on the blocking plate and continuously accumulated in the water level holding hole, the blocking plate can not be normally lifted In this case, there is a problem in that backflow of the odor can not be prevented because blocking of the bottom of the drain hole by the blocking plate is impossible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view illustrating a coupling relationship between components of a drain trap for preventing bad odor backflow according to an embodiment of the present invention; FIG.

As shown in FIG. 1, the drainage trap is largely composed of a trench and a sleeve tube. The drainage of the contaminated sewage flowing into the sewage pipe installed in the space drain pipe having a large amount of water, such as a bathroom, A cover basket 100 embedded in a space bottom at the upper end of the sewer and a drain cover 200 internally housed so as to be detachable from above the cover basket 100. [

The cover basket 100 internally accommodates the drain cover 200 and is formed to have a recessed portion for guiding a drainage flow to the sleeve pipe 300 and a mounting end portion having a stepwise downward step, The sleeve tube 300 is further formed with a compression tube portion for inserting the upper end of the sleeve tube 300 so as to surround the outer surface of the sleeve tube 300.

The drain cover 200 is provided with a plurality of drain holes passing through the drain cover for drainage of falling sewage, and a plurality of drain holes for guiding a drainage flow of the sewage flowing down to the drain pipe, So that they are formed at regular intervals.

Although not specifically shown in FIG. 1, a plurality of through holes may be formed in order to filter out foreign substances such as hair and debris and smooth drainage.

The sleeve pipe (300) is a means for blocking the backflow of the odor generated due to the decay of the sewage flowing into the sewer pipe in addition to the induction of the flow of the sewer pipe through the trench, The sewer pipe is formed in the shape of a pipe so that the sewage that has passed through the trench flows into the sewer pipe. The outer surface of the upper end of the sewer pipe is formed with a latching protrusion so as to be mounted on the cover basket 100.

FIG. 2A and FIG. 2B are operation states showing the inside of a sleeve tube of a drain trap for preventing bad odor backflow according to an embodiment of the present invention.

As shown in FIGS. 1, 2A, and 2B, drainage can be performed when sewage having a predetermined load or more flows into the sleeve pipe 300. In contrast, when the load of the sewage is removed, The blocking unit 500 is installed transversely to the interior of the sleeve 300 through the pivot pin 400. [

In this case, the main body of the sleeve tube 300 is symmetrically formed with the pin fixing holes 310 so that the rotation pin 400 can be inserted through the center of the sleeve tube 300 .

The blocking part 500 is formed in a hinge shape and has a hinge structure of a hinge structure for allowing the blocking part 500 to be laterally fixed to the inside of the sleeve pipe 300, 510 and a pair of blocking plates 520 coupled to the hinge unit 510.

At this time, the blocking plate 520 is pivoted downward by the load of the sewage water to the bottom of the pair of blocking plates 520 to drain the sewage, and if the load is reduced or removed after the sewage is drained The elastic plate 550 is pivoted so that both sides of the elastic plate 550 correspond to each other in order to generate elasticity in which the blocking plate 520 is pivoted upward and the end of the blocking plate 520 hits the inner side surface of the sleeve tube 300 Respectively.

The elastic member 550 is a means for absorbing or storing energy by being deformed by an external force and using elasticity that returns to its original state when the force is removed, And is fixed to the lower portion of the blocking plate 520.

Particularly, in the embodiment of the present invention, although the elastic member is formed by a spring, the elastic member is not limited to this, and may be formed in any form as long as it is deformed by an external force and has a property of returning to its original shape when a force is removed .

Accordingly, when the sewage over a certain load is drained, the elastic member 550 is deformed to reduce the angle formed by the pair of the blocking plates 520, thereby discharging the sewage to the sewage pipe. After the drainage is completed, The angle formed between the pair of shield plates 550 becomes large due to the property that the load is reduced or removed and thus the elastic member 550 returns to its original shape, It comes into contact with the inner surface of the pipe and basically blocks offensive odors that flow backward from the sewer pipe.

The mounting adapter 600 is formed in the center of the sleeve tube 300 so as to be inserted into the upper portion of the sleeve tube 300 and has a through hole having a size corresponding to the sleeve tube 300. The installation adapter 600 is intended to be applicable to a cover basket 100 manufactured to have drain holes of various sizes.

The mounting adapter 600 may be inserted into the inner diameter of the sleeve tube 300 and may be engaged with a locking protrusion formed on the outer circumferential surface of the upper end of the sleeve tube 300.
