Description

An Odor backflow prevention sewer trap with improved assembly and durability}

The present invention relates to a sewer trap having improved assembly and durability.

Drains located indoors, such as toilets, showers, and sinks, are generally open to communicate with the sewer at all times, so there is a problem that bad odors flow back through the sewer, causing discomfort, or bacteria or viruses flowing or propagating through the sewer are introduced into the room. .

In order to solve this problem, various types of sewer traps have been developed, commercialized and released on the market, and an example of this is the sewage odor prevention device disclosed in Korean Patent Registration No. 10-1113539.

In the sewer trap according to the above example, the state in which the rotating cover closes the incision hole is usually maintained by the return means, which is a torsion spring. is using the method to be

The torsion spring of the conventional sewer trap is formed by tightly coiling a thin metal rod so that the rotating cover can easily rotate at low water pressure, and is fixed to the housing by a separate coupling pin of the torsion spring.

Therefore, in the process of assembling the sewer trap, the torsion spring and the coupling pin, which are small-sized parts, must be precisely positioned and assembled one by one, which inevitably takes a lot of time and manpower in the manufacturing process.

In addition, when the torsion spring is used, there is a problem in that the support part for supporting the rotating cover is thin, so there is a high probability of damage in the process of assembling or repeatedly using it.

In addition, in the conventional sewer trap, since the gap between the coiled parts of the torsion spring is very narrow and the peripheral structure thereof is complicated, various molds and bacteria grow and cause another hygiene problem, and in addition, a bad odor is caused by foreign substances. can cause serious problems.

The present invention has been devised to solve the above problems of the prior art, and it is an object of the present invention to improve the assembly and durability of a sewer trap.
