Dry-wet dual stinking-proof and anti-backflow floor drain

Abstract

The invention relates to a dry-wet dual stinking-proof and anti-backflow floor drain. The floor drain comprises a floor drain box, a dual proofing device and an eave-shaped water channel stinking-proof cover; it is characterized in that the dual proofing device is composed of a water storage pipe, a T-shaped folding and unfolding door, a spring storeroom and a spring and a hollow ball; the foldingand unfolding door is used for sealing a drainage channel of the water storage pipe so as to firstly prevent stink leakage of building pipelines; a hollow ball is placed on a hanging rod; after a building pipeline is blocked, the hollow ball is held up by the rising water so that the water outlet of the water storage pipe is blocked; therefore, the channel of water backflow is blocked so as to prevent water backflow; a water flow channel is formed between the bottom of the eave-shaped stinking-proof cover and the bottom of the floor drain box so that the depth of water flow is increased and the water seal depth of the floor drain is increased. The water storage pipe in the floor drain box is covered by the eave-shaped water channel stinking-proof cover; partial stink leaking from the folding and unfolding door goes to the floor drain box and is blocked by the eave-shaped water channel stinking-proof cover in the water; therefore, second step of stinking-proof is achieved.

Description

Technical field: [0001] The invention relates to a floor drain that drains from the ground to a building's pipeline, and particularly relates to a "drought water dual anti-odor and anti-inversion floor drain". Background technique: [0002] Currently, none of the floor drains on the market that are used on the ground to drain building pipes meet national standards, and have the following major defects: they cannot prevent building pipes from leaking indoors, the pipes are blocked, and water is poured indoors through floor drains. Summary of the invention: [0003] The content of the present invention is to overcome the shortcomings stated in the above background art and propose a "drought water dual anti-odor and anti-inversion floor drain" (hereinafter referred to as: floor drain) in order to achieve the above purpose, the technical solution of the present invention is based on patent application number ZL201620361511 .0, certificate number 笫5527337, the name of the utility model...
