Description

Technical field [0001] The present invention relates to a filter element, in particular to a detachable filter element, a filter element assembly and a water purifier containing the filter element assembly. Background technique [0002] Existing market water purifiers usually use multiple filter elements for multi-stage progressive filtration. Each filter element has a limited lifespan. After a certain period of time, the filter element that has reached the end of its life needs to be replaced to maintain the normal filtration function of the water purifier and ensure the water flow. And water quality. [0003] Existing water purifiers have problems such as many filter elements, troublesome replacement of the core, high frequency of replacement of the core, and high cost. There are mainly the following two ways to replace the core: (1) Disposable replacement: the filter bottle body of the filter element and the cap of the filter bottle are fixedly connected by spinning and melting...
