Odor-resistant floor drain

Abstract

The invention discloses an odor-resistant floor drain. The odor-resistant floor drain comprises an embedded box and a floor drain cover plate, wherein the lower part of the embedded box is detachably connected with a hollow floor drain main body, the upper part and the lower part of the floor drain main body are communicated, a hollow connecting seat is arranged in the floor drain main body, a guiding column is arranged in a center hole of the connecting seat in a sliding matching manner, the lower end of the guiding column is connected with a seal cover, and an elastic piece is arranged in the center hole of the connecting seat; the upper end of the guiding column is connected with an elastic sealing ring; the elastic sealing ring comprises an annular connecting part and an elastic sealing body; the annular connecting part is made from hydrogenated acrylonitrile butadiene rubber, the elastic sealing body comprises is prepared from the following components in parts by weight: 70 parts of styrene-butadiene-styrene block copolymer, 10-20 parts of aromatic hydrocarbon oil, 5-8 parts of polyethylene, 4-6 parts of alumina powder, 0.2-0.4 part of diphenylamine and 0.5-2 parts of nano silver. The odor-resistant floor drain has better sealing performance, high odor resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a deodorant floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. Now families choose to use deodorant floor drains to eliminate ordinary floor drains. At present, according to the principle of deodorization, deodorant floor drains can be divided into water seal deodorization, deodorization with cover and deodorization with floating ball. Water seal deodorization is generally to install a water storage bend in the drain pipe of the floor drain, and use the accumulated water in the water storage bend to seal and deodorize, but because the accumulated water is prone to bacteria and other harmful microorga...

AI Technical Summary

Problems solved by technology

The floor drain of this structure has a certain anti-odor function, but because the sealing cover at the lower end of the floor drain is to realize the sealing of the lower end of the water seal body under the elastic force of the spring, if the spring is used for a long time, it will easily cause fatigue, thereby reducing the elastic force of the spring, resulting in a tight seal. The seal between the cover and the lower end of the water seal body is not tight, and the anti-odor effect is poor; in addition, when the sewage is discharged through the lower end of the water seal body, impurities or oily slime in the sewage are easy to stick to the sealing cover, resulting in a poor seal of the sealing cover. It is necessary to clean the sealing cover frequently to ensure its sealing performance.

Moreover, when the pressure of the sewage is not enough to overcome the elastic force of the spring, the sealing cover seals the lower end face of the water seal main body under the elastic force of the spring. At this time, some accumulated water remains in the water sealed main body. Odor, the generated odor will volatilize into the room through the upper end of the water seal body, so the anti-odor effect of the floor drain is poor
