Replaceable multistage composite filter element

Abstract

The invention discloses a replaceable multi-stage composite filter element. The composite filter element comprises a shell and a filtering mechanism; the filtering mechanism is arranged in the shell and comprises a pre-filtering module, a fine filtering module and a post-processing module; and the pre-filtering module and the post-processing module are both located in the fine filtering module. According to the composite filter element, the pre-filtering module and the post-processing module are both arranged in the fine filtering module, and the water passing area and the flow of a filteringmaterial can be increased due to the unique arrangement of the filtering mechanism. Meanwhile, the structure is very simple in design and small in size, and therefore the occupied space of the whole machine can be smaller. Besides, joints of the composite filter element are of one-way water stop structures, and the number of the joints is small. Meanwhile, water does not flow when a user replacesthe filter element, and the experience degree is good.

Description

technical field [0001] The invention relates to a replaceable multistage composite filter core. Background technique [0002] In the water purifiers currently on the market, due to the different functions of treating water quality, two or more filter elements are generally required, which results in a large volume of the water purifier; the method of using multiple filter elements at the same time will easily lead to many interfaces and water leakage Risky. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a replaceable multi-stage composite filter element. [0004] The present invention is achieved through the following technical solutions: a replaceable multi-stage composite filter element, comprising a casing and a filter mechanism, the filter mechanism is placed in the casing, and the filter mechanism includes a pre-filter module, a fine filter module and a post-treatment module, where...
