Floor drain

Abstract

The invention discloses a floor drain which comprises a floor drain body, a filter screen plate and a cover body. The bottom of the floor drain body comprises a drainage port and an annular table arranged on the periphery of the drainage port. The filter screen plate is a filter plate structure provided with an opening formed in the center and provided with a lateral edge on the periphery, an annular barrier is arranged at the opening position, an annular barrier region corresponds to the drainage port region and is equal to the drainage port region in size, and multiple supporting columns are arranged under the bottom of the filter screen plate. The cover body is a grid-shaped cover plate provided with a closed region at the center, and the closed region corresponds to the annular barrier region and is slightly greater than the region. The floor drain further comprises an odor-preventing mechanism. The floor drain enables waste water to be dispersedly filtered at a water inlet away from a sewer pipe through the arranged annular table and the filter screen plate provided with the annular barrier, the shortcoming that all existing floor drains centralize impurities at the water inlets of the sewer pipes for filtration and blockage is easily caused is overcome, the effects of dispersing water flows and performing filtration in advance are well achieved, and the floor drain is good in anti-blocking effect, is easy to clean and further has water sealing and deodorizing functions.

Description

technical field [0001] The invention relates to the technical field of bathroom cleaning, in particular to a floor drain. Background technique [0002] Floor drains are common sanitary components in daily life, and it is often necessary to install floor drains for drainage in toilets, bathrooms or balconies. Existing floor drains generally consist of a floor drain main body, a retaining screen and a floor drain cover; the lower port of the floor drain main body is equipped with a short pipe, which can be connected to the sewer pipe, and the retaining screen is arranged directly above the lower port of the floor drain main body, mainly to block Used for stolen goods to prevent the stolen goods from falling directly into the sewer pipe to block the pipe. The floor drain cover is set on the upper port of the floor drain body, generally in the shape of a grid. But the main disadvantage of this kind of floor drain is: all belong to the floor drain of "centralized filtration", th...

Problems solved by technology

But the main disadvantage of this kind of floor drain is: all belong to the floor drain of "centralized filtration", that is, the water carries hair and other sundries and is concentrated at the lower port of the floor drain main body to filter, and it is easy to make hair and other sundries get stuck in the throat Above the channel (lower port of the main body of the floor drain), this will bring greater obstacles to the drain that would have caused the throat effect. When hair and debris accumulate, it will cause poor water flow or blockage

[0003] This shows that the above-mentioned existing floor drain obviously still has inconvenience and defects in structure, method and use, and needs to be further improved urgently
