Floor-drain structure

Abstract

The invention aims at providing a floor drain structure, which can realize automatic deodorization, cockroach prevention and backflow prevention regardless of whether the floor drain is dry or not. The floor-drain structure includes a main body, wherein an upper part of the main body is provide with a water inlet; a lower part of the main body is provided with a water discharge port and an annularwater storage chamber surrounding the water discharge port; a water seal floating block for plugging the water outlet is also arranged above the water outlet; the water seal floating block comprisesan annular side wing extending into an annular water storage chamber; a sealing ring for preventing backflow is arranged above the water seal floating block; and the sealing ring is fixed on the innerwall of the main body. The floor drain structure of the invention can realize automatic deodorization, cockroach prevention and backspill prevention no matter whether the floor drain is dry or not, and the floor drain structure has convenience and reliability without other operation of the occupant after installation.

Description

technical field [0001] The invention relates to a drainage appliance, in particular to a floor drain structure. Background technique [0002] The floor drain is a drainage device that connects the ground to the drainage pipeline system. It needs to remove ground water, water stains, solid objects, fibrous objects, hair, and easy sediments. The main function of the floor drain: [0003] Anti-odor, anti-clogging, anti-cockroach, anti-water return, anti-drying (mainly refers to the water-sealed floor drain). [0004] At present, the anti-odor function of the floor drain is mainly realized through the trap. Specifically, either the drain pipe is an elbow, or there is a trap structure in the floor drain to form a liquid seal to prevent the sewer odor from overflowing into the bathroom. The anti-clogging function mainly prevents the hair and other sundries from entering the floor drain by setting grates on the floor drain, and collects them into the garbage basket. Anti-cockroa...

AI Technical Summary

Problems solved by technology

[0005] The defects of the current technology are: (1) Water-sealed floor drain, that is, a floor drain that uses a water trap to prevent odor. The problem

(2) The method of sealing the floor drain through the floor drain cover requires manual operation, and since the floor drain does not need to be sealed at ordinary times, it is not easy for residents to think of the need to seal the floor drain before going out for a long time

And if the resident goes out for a long time and forgets to seal the floor drain with a floor drain cover, once a back overflow occurs, it will cause difficult-to-clean pollution to the bathroom and even the entire house, and it will also breed cockroaches, with serious consequences

(3) The function of the existing floor drain is relatively single, such as Chinese patent CN201420425440.7, which solves the problem that the floor drain cannot be deodorized and cockroach-proof after the water in the trap dries up, but the problem of anti-flooding has not been solved yet, and there is still no one on the market. This type of floor drain can achieve automatic deodorization, anti-cockroach and anti-overflow effects at the same time when the floor drain has water or is dry.
