Multilayer water purification filter core and its water purifier

Abstract

The invention discloses a multilayer water purification filter core and its water filter. The filter core includes a filter layer and a filter core cover, the filter layer comprises an outer filter screen layer, an activated carbon layer and an inner filter screen layer, and the activated carbon layer is positioned between the outer filter screen layer and the inner filter screen layer. The outer filter screen layer includes an outer filter screen, an outer frame and an outer sealing cover, and the outer frame is the support frame of the outer filter screen. The upper portion of the outer frame is in threaded connection with the filter core cover, and the lower portion of the outer frame is in threaded connection with the outer sealing cover. The inner filter screen layer comprises an inner filter screen, an inner frame and an inner sealing cover, and the lower portion of the inner frame is in threaded connection with the inner sealing cover. The filter core and the water purifier have the following advantages: the increase of the number of the filter layer and the compressed activated carbon makes discharged water clean; structure between the outer filter screen and the inner filter screen and between the outer filter screen and the filter core cover are detachable, so cleaning is convenient, and the filter area is increased; and when the middle compressed activated carbon layer reaches saturated adsorption, only the activated carbon layer is individually replaced, so the use cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of water purification, in particular to a multi-layer water purification filter element and a water purifier. Background technique [0002] As water pollution continues to intensify, the issue of drinking water has attracted more and more attention, and water source cleaning technology was born. Among them, water filtration is one of the most commonly used technologies in water source cleaning technology. The filter element is one of the core components of the filtration equipment. After the water is filtered by the filter element, it can reach the drinking water standard. [0003] Various types of water purification products have been developed and produced at home and abroad. Generally speaking, the filter element materials generally use one or more active materials such as granular activated carbon and molecular sieves. These materials are directly installed in the water purifier, although it can be removed Hea...

AI Technical Summary

Problems solved by technology

[0003] All kinds of water purification products have been developed and produced at home and abroad. Generally speaking, one or more active materials such as granular activated carbon and molecular sieve are generally used as the filter element materials. These materials are directly installed in the water purifier, although they can be removed. Heavy metals, pesticides, organic matter, etc., but the structure of this filter element is complex and the price is high

[0004] Activated carbon is often used inside the filter element as a filter, but after a period of use, the adsorption of activated carbon reaches saturation, and the adsorption force decreases or even disappears. If it continues to be used, the adsorption effect will not be achieved. Replacing the entire filter element is not only costly, but also causes waste and pollution to the environment, which needs to be improved urgently
