Problems solved by technology

[0004] However, the problem with the above-mentioned technology is that the filter elements are all disposable structures and must be discarded after use.
As a result, the cost increases; sometimes the problem of secondary or multiple pollution occurs
In addition, the filter element has a single function, and the filter material cannot be replaced.

Abstract

The invention provides a filter core with a replaceable filter material, comprising a cylindrical filter core shell used for storing the filter material and an end cover. The filter core is characterized in that the filter material is granular active carbon filter material; a water inlet at the bottom of the filter cylinder is provided with two layers of sponges used for filtration and a non-woven cloth protection layer; a round hole typed non-woven filter layer and a round water-retaining cap are embedded at a water outlet; an anti-leakage washer is arranged outside the water outlet of the filter cylinder; and the filter core structure can replace the filter material or mixes the filter material with other functional filter materials for use, and can be repeatedly used for many times. Therefore, the filter core reduces the cost, saves the energy resource, and avoids the problems of secondary pollution or multi-time pollution. The filter core with the replaceable filter material has wide applicable area and range, is economical and has large market potentials.

Description

technical field [0001] The invention relates to a filter element for purifying water, in particular to a replaceable filter element for purifying drinking water. Background technique [0002] With the continuous progress and development of social economy and the improvement of people's increasing material life and health needs, people's requirements for drinking water safety standards are also getting higher and higher. [0003] For example, based on the fact that tap water is chlorinated and sterilized, a large amount of carcinogenic organic chlorides are generated, which makes the water quality of tap water not only poor, but also has a strong odor, and its taste is very unpalatable. There is no purification treatment of organic matter in domestic tap water. The drinking water that has appeared includes cylindrical water purification, drinking water filters, etc., to filter impurities, purify, disinfect, sterilize, and even add nutrients and health care ingredients to drin...
