Water grate capable of preventing evaporation of water

Abstract

A water grate capable of preventing the evaporation of the sealing water of a floor drain is provided with a plurality of rectangular drain holes (2), a corresponding rectangular check valve (5) is arranged under each rectangular drain hole (2), and a hinge of the rectangular check valve (5) is arranged on one long side of the rectangle. The check valve (5) is made of an elastic rubber board (3) with three cuts (4) corresponding to the rectangular drain hole (2), which has the same size as the whole water grate does. The check valves (5) arranged on the water grate can prevent the sealing water stored in the floor drain from being in contact with the air, consequently, the water cannot be evaporated to be reduced after a long time, and the sealing reliability of the water sealing type floor drain is guaranteed; the structure of the check valve made of the rubber board (3) is simple, and the cost is almost not increased. The design idea of arranging the check valves on the water grate breaks through the long-standing idea, and solves the problem of easy water evaporation in the water sealing type floor drain, which cannot be solved for a long time.

Description

technical field [0001] The invention belongs to a water-proof and evaporation water grate used on the bathroom floor drain. Background technique [0002] No matter what kind of pattern the water grate used for the bathroom floor drain is made, it has a number of drainage holes that can pass through the designed drainage and filter large debris, often called water grates. There is no technical content except for the appearance requirements. [0003] Modern bathroom floor drains take a variety of technical measures to prevent odor, but none of them can be as reliable as the most traditional water seal. However, the floor drains used in modern bathrooms have relatively high appearance requirements, so the traditional cast iron floor drains have long been eliminated. The problem is that modern floor drains such as stainless steel have small diameters and low heights, so their water storage is relatively small, and they are often easily evaporated. Therefore, there are a large ...

AI Technical Summary

Problems solved by technology

The problem is that modern stainless steel and other floor drains have small diameters and low heights, so their water storage is relatively small, and they are often easily evaporated. Therefore, there are a large number of floor drains with check valve structures at the downpipes.

However, the structural failure rate of this kind of check valve directly installed on the downpipe is relatively high, and it is not easy to be found when a failure occurs, and it is very troublesome to deal with it, so the effect is not very ideal

This kind of design idea of ​​setting the check valve on the downpipe is bound by the traditional design idea, so it is difficult to extricate itself. Therefore, there is no floor drain with a check device on the water grate.
