Abstract

The utility model provides an anti-odor, anti-insect and anti-return water floor drain, which comprises a floor drain bowl provided with an annular water seal groove and a floor drain cover fastened on the floor drain bowl. The bottom of the floor drain cover is provided with a short pipe corresponding to the water seal groove. The reason is: the upper end of the inner wall of the water seal tank is inclined inward to form a circular platform, the lower end of the short pipe surrounds the circular platform, and there are water leakage holes evenly distributed around the short pipe on the floor drain cover, and a lower cover and a floating ball are added, wherein the lower cover The thread is fixed on the bottom of the floor drain bowl, the center of the lower cover is provided with a water outlet, and the floating ball is blocked on the water outlet, and the diameter of the floating ball is larger than the diameter of the upper end surface of the round table. When there is no water flowing into the floor drain, the floating ball will be sealed at the water outlet by its own weight to prevent odor from coming out or insects from crawling out; The water is discharged into the sewer; when the water in the sewer flows back upwards, the floating ball and the inner end face of the round table are blocked, so that the returning water cannot enter the water seal tank, thereby realizing the anti-return water.

Description

Anti-odor anti-insect anti-return water floor drain

Technical field

The utility model provides an anti-odor, insect-proof and water-return-proof floor drain, which belongs to the technical field of drainage devices.

Background technique

The floor drain used now generally consists of two parts: a housing and a water seal. There is a ring-shaped water seal groove on the shell, and the water seal cover is in the shape of an inverted cup. The lower cup body of the water seal cover is inserted into the middle of the water seal groove. When in use, running water falls into the water seal groove to form a circular turning bay. , Prevent the odor in the underground pipeline from emerging, and play the purpose of deodorization. This kind of floor drain has two disadvantages: (1) when there is no water inflow for a long time, the water level of the water seal tank is low or dry, and there is no water seal effect, and the odor in the sewer pipe will emerge, parasitic in the sewer pipe Bedbugs, cockroaches, etc. in the water are also very easy to crawl out from the drain. (2) When the sewer is blocked, it is easy to have backflow and backflow at the floor drain, which will affect indoor sanitation.

Utility model content

The purpose of the utility model is to provide an anti-odor, anti-insect and anti-return water floor drain which can overcome the above-mentioned defects and has excellent performance.

Its technical content is:

It includes a floor drain bowl with an annular water seal groove and a floor drain cover fastened on the floor drain bowl. The bottom of the floor drain cover is provided with a short pipe corresponding to the water seal groove, and the lower end of the short pipe penetrates into the water seal groove. It is characterized in that: The upper end of the inner side wall of the sealing groove is inclined inward to form a round platform, and there are leaking holes evenly distributed around the short pipe on the floor drain cover, and a lower cover and a floating ball are added, wherein the lower cover thread is fixed on the bottom of the floor drain bowl, and the bottom cover of the lower cover A water outlet is arranged in the center, and a floating ball is blocked on the water outlet, and the diameter of the floating ball is greater than the diameter of the upper end surface of the round table.

In the anti-odor, anti-insect and anti-return water floor drain, the water outlet of the lower cover is spherical.

Its working principle is: there is accumulated water in the water seal tank, and the lower end of the short pipe penetrates into the water seal tank to form a water seal with the accumulated water in the water seal tank. When no water flows into the floor drain, the floating ball is blocked at the water outlet by its own weight to prevent odor from coming out or insects from crawling out; In the cavity formed by the cover and the floating ball, the floating ball floats up to open the water outlet to discharge the accumulated water into the sewer; when the water in the sewer flows back upwards, the floating ball floats upward under the action of water buoyancy, and due to the The diameter is larger than the diameter of the upper end surface of the round platform, so the floating ball will eventually be blocked with the inner end surface of the round platform, so that the returning water cannot enter the water seal tank, thereby realizing the anti-water return.

Compared with the prior art, the utility model can deodorize, prevent insects, and prevent water return and backflow, and is especially suitable for occasions where the floor drain is not frequently used for drainage, and has excellent performance.
