Anti-seepage structure of sewer device

Abstract

The invention belongs to the technical field of sewer devices, and particularly relates to an anti-seepage structure of a sewer device. The anti-seepage structure comprises a water receiving platform, wherein a sewer opening is formed in the middle of the water receiving platform, a floor drain installation position is arranged on the upper side of the sewer opening, and a floor drain core is arranged in a floor drain; a drainage face with the high outer portion and the low inner portion is arranged at the top of the water receiving platform; the drainage face collects water falling on the water receiving platform to the sewer opening, a water retaining ring is arranged on the peripheral side of the sewer opening, a plurality of first water passing holes are formed in the wall face of the water retaining ring, a rubber ring is arranged on the inner side of the water retaining ring, and gaps for water flow to pass through are formed between the rubber ring and the first water passing holes; and when the pressure of the inner side of the rubber ring reaches the set condition, the rubber ring can expand outwards and be attached to the first water passing holes. Accordingly, water seeping from the gaps is received through the water receiving platform, then the drainage face of the water receiving platform guides accumulated water to flow to the sewer opening to be drained, and finally the phenomenon that the accumulated water remains on a cement bottom plate, and consequently a room generates peculiar smells is avoided.

Description

technical field [0001] The invention relates to the technical field of sewer devices, in particular to an anti-seepage structure of a sewer device. Background technique [0002] The floor drain is an important interface connecting the drainage 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. [0003] Existing floor drains are usually made of metal, which cannot be tightly combined with cement. A certain gap will be formed between the side wall of the floor drain and the cement floor; during the process of launching water, the water will seep into the bottom plate along the gap and accumulate in the ground, causing the room Odor or even damage. Contents of the invention [0004] The purpose of the present invention is to provide an anti-seepage structure of a water launching device, which solves the problem th...
