According to the technical scheme, an anti-overflow cavity is formed inside a main shell, an opening of a water seal cover faces downwards and covers the upper portion of the anti-overflow cavity, a water seal is formed between the main shell and the anti-overflow cavity, and a water inlet grate is installed above the main shell; according to the structure of the anti-overflow cavity, a water drainage outlet is formed in the bottom of a water drainage cavity, a cover is arranged on the top of the water drainage cavity, a top board of the cover is provided with at least two round water via holes, an anti-overflow ball is arranged below each round water via hole, the diameter of each round water via hole is smaller than that of the corresponding anti-overflow ball, and a guide board is arranged beside each anti-overflow ball and is used for preventing the anti-overflow ball from falling into a sewer line through the water drainage outlet; the bottom of the main shell is provided with a water outlet, and the water drainage outlet of the water drainage cavity is communicated with the water outlet of the main shell.

Description

technical field [0001] The invention discloses a large-flow anti-backflow anti-drying water-seal anti-odor safe floor drain that can discharge floods and belongs to the technical field of floor drains. Background technique [0002] The floor drain is an important interface connecting the sewer system and the indoor ground. As an important part of the residential drainage system, its performance directly affects the quality of the indoor air, and is even very important to the healthy quality of life of the people in the house. [0003] At present, there are mainly several types of building drainage floor drains on the market, such as ordinary water-sealed type, mechanically-sealed type, and floating body valve deodorization type, and these types have some shortcomings that are difficult to completely overcome. Examples are as follows: [0004] Ordinary water seal type: the height of the water seal is not up to the standard, the water seal is easy to dry up, it cannot prevent ...

AI Technical Summary

Problems solved by technology

[0004] Ordinary water seal type: the height of the water seal is not up to the standard, the water seal is easy to dry up, it cannot prevent back overflow, it is easy to block and the drainage speed is slow

[0005] Mechanically closed type: the seal is not tight, the parts are easily damaged and aged, the reliability is extremely poor, and the product life is not long

[0006] Float valve anti-odor type: the seal is not tight, the parts are easy to damage and fail, and the structure is complicated and difficult to maintain

[0007] The drainage speed of the above-mentioned drainage floor drains is not high, far below the speed of 1L / s stipulated by the national standard. When the faucet is forgotten or the water pipe bursts, the water will accumulate seriously; the anti-odor effect is not good; there is no anti-overflow structure Or the anti-backflow is unreliable, which affects the drainage speed; and none of them have good connection performance appliance drainage joints, which cannot meet the drainage requirements of people's daily life
