AI Technical Summary

Technical Problem

Existing floor drain products are easily clogged by hair and have a small drainage space, resulting in discomfort and a short lifespan.

Method used

A double-filtration and anti-blocking floor drain device is designed, including a floor drain base, a drainage panel and an anti-blocking filter body. It adopts a grid structure of a central swirl part, a peripheral swirl part and an edge part. The filter hole is designed to be vortex-shaped to increase the drainage volume and simulate the water vortex mode to guide and drain water. At the same time, a handle is provided on the anti-blocking filter body for easy cleaning.

Benefits of technology

It effectively prevents the floor drain from being washed away, increases drainage volume, reduces the chance of blockage, improves comfort and lifespan, and the service life can reach more than 10 years.

Abstract

The utility model discloses a double-filtration anti-blocking floor drain drainage device which comprises a floor drain base, a drainage panel and an anti-blocking filter screen body. A drainage chamber is concavely arranged in the middle of the floor drain base, and an upper limiting groove is formed in the top extension edge of the drainage chamber; a lower limiting groove is formed in the bottom of the lower water chamber; a drainage opening is formed in the center of the bottom of the drainage cavity; an edge part, a peripheral rotational flow part and a central rotational flow part are sequentially arranged on the anti-blocking filter screen body from the periphery to the center; the central rotational flow part is sunken in the peripheral rotational flow part to form a rapid water guide and drainage area, the central rotational flow part is provided with a first filter hole, the peripheral rotational flow part is provided with a second filter hole, and the first filter hole and the second filter hole are consistent in rotation direction. According to the floor drain drainage device, the floor drain net can be prevented from being washed away, meanwhile, the drainage amount is increased, the blocking probability of the floor drain net is reduced, the use comfort of the floor drain drainage device is fundamentally improved, the service life of the floor drain drainage device is fundamentally prolonged, and the service life of the floor drain drainage device can exceed 10 years through the design.
