Description

Sewer odor prevention device {APPARATUS FOR PREVENTING ILL-SMELLING OF A DRAINAGE}

The present invention relates to a sewer odor prevention device for preventing odor generated by backflow through the sewer of the home sewer or road manhole.

As is well known, sewers are for draining sewage used by rainwater, homes, factories, hospitals, etc., and such sewers have sewer pipes buried in the ground and discharge passages communicated above the sewer pipes. The side is provided with an installation port, which is provided with a grating structure or a drain cover having a plurality of holes. Thus, after various sewage flows into the sewer pipe through the sewer cover, the sewage passing through the sewer pipe is discharged to the sewage treatment plant.

On the other hand, the odor prevention port having a predetermined discharge passage is provided on the installation port side of such a sewer can prevent the odor flowing back from the sewer pipe.

However, such a conventional malodor prevention tool has a disadvantage in that the sewage discharge is not smooth because of the foreign matter or various sediment contained in the sewage on the discharge passage side, thereby reducing the efficiency of the malodor prevention extremely.

Accordingly, Korean Patent No. 10-068937 (name: sewage odor prevention zone, hereinafter referred to as a pre-registered patent) has been disclosed that facilitates sewage discharge and improves odor prevention efficiency.

The pre-registered patent includes a sewer mounting portion and a body of synthetic resin material extending to the sewer mounting portion, wherein the body portion is opened when the sewage is discharged and closed when there is no discharge of sewage so that the odor of the sewer flows backward. It is characterized by preventing.

However, the pre-registered patent has a disadvantage that the body portion made of synthetic resin material can be easily damaged when the pedestrian discards the cigarette fire or discharges hot water through the sewer cover.

The present invention has been made in view of the above, and an object thereof is to provide a sewer odor prevention device capable of preventing damage caused by external heat such as cigarette fire or hot water.

In addition, it is an object of the present invention to provide a sewer odor prevention device to make the opening and closing operation of the body portion more smoothly.

Sewer malodor prevention device according to an embodiment of the present invention for realizing the above object, the mounting portion is mounted to the sewer side; A communication part connected to the mounting part, first and second side wall parts extending from a lower part of the communication part to allow the inner side surfaces to be in close contact and opening with each other, and first and second connecting both ends of the first and second side wall parts; It includes a body portion having a corner portion, wherein the body portion is made of a synthetic resin substrate and the heat-resistant coating layer coated on the inner and outer surfaces of the substrate.

The mounting portion may further include a return member for returning the inner surfaces of the first and second sidewall portions to be in close contact with each other at positions corresponding to the first and second corner portions.

The return member may be coated with a protective layer of a synthetic resin material in contact with the body portion.

At least one elastic band is provided on the outer surfaces of the first and second sidewall portions.

The body portion and the return member may be integrally formed with the mounting portion.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

Prior to this, the terms or words used in this specification and claims are not to be interpreted in a conventional and dictionary sense, and the inventors may appropriately define the concept of terms in order to best explain their invention in the best way possible.
