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.

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.
