Sterilizing filtering element and water purifying device utilizing same

Abstract

The invention discloses a sterilizing filtering element and a water purifying device utilizing the same. The sterilizing filtering element adopts solid state slow-release type sanitizer and can slowly release residual chlorine; the chlorine release concentration can be controlled; the disinfection effect is good; the water purifying device adopting the sterilizing filtering element adopts a multistage filtering element structure; first an upper filtering element in an upper barrel performs preliminary filtering to water by removing particle impurity in the water; then a sterilizing filtering element positioned in a middle barrel releases residual chlorine through the slow-release type sanitizer containing chlorine to sterilize the water filtered by the upper filtering element, so as to obtain good disinfection effect; and finally a lower filtering element positioned inside a lower barrel removes harmful substance, such as the residual chlorine, organic substance and disinfection by-product, in the water sterilized by the sterilizing filtering element, so that outlet water quality is better and safer, and simultaneously the mouthfeel of the water is improved. In addition, the water purifying device has a small size, is convenient to use and is particularly to families in regions where the water quality is poor.

Description

technical field [0001] The invention relates to a household water purification device, in particular to a disinfection filter element and a water purification device using the filter element. Background technique [0002] At present, there are many sterilizing water purifiers on the market, including ultraviolet lamp (UV) sterilizing water purifiers, iodine resin sterilizing water purifiers, bromine resin sterilizing water purifiers, ozone sterilizing water purifiers and ultrafiltration membrane water purifiers, etc. All can achieve the effect of removing bacteria; the above-mentioned various sterilizing water purifiers have their own shortcomings, as follows: UV lamp sterilization and ozone sterilizing are more troublesome to use in household water purifiers. Used together with electricity, the safety performance requirements of the product are relatively high, and the poor protection of ultraviolet rays and excessive ozone overflow will have a certain impact on human healt...

AI Technical Summary

Problems solved by technology

Therefore, the disinfection effect of the existing household water purification devices is relatively poor, and the design of the filter structure is not reasonable enough, and the quality of the effluent water needs to be further improved.
