Composite filter element assembly with integrated water gap at one end and mounting head matched with composite filter element assembly

Abstract

The invention discloses a composite filter element assembly with one integrated end of a water gap and an installation head matched with the composite filter element assembly, which comprises an external filter element and a built-in rotary filter element, wherein the built-in rotary filter element is coaxially arranged inside the external filter element, and the open end of the built-in rotary filter element always extends and protrudes out of the end face of the open end of the external filter element, the built-in rotary filter element can freely rotate relative to the external filter element around an axis, the combined open end of the external filter element and the built-in filter element is provided with a water inlet and a water outlet, a mounting head and the opening end of the built-in rotary filter element are respectively provided with rotary clamping and fixing structures, and the rotary clamping and mounting and dismounting of the mounting head are achieved through the rotation of the built-in filter element. According to the invention, a plurality of water inlets and outlets are integrated at one end of the composite filter element assembly in a multi-stage filter element compounding way, and the butt joint of the multi-stage filter element and the mounting head adopts a mounting and dismounting structure and a convenient rotary clamping structure, so that the multi-stage fine filtration of the single filter element is achieved, the structure is simple with good sealing stability and installation and disassembly of the filter element are extremely convenient.

Description

technical field [0001] The invention relates to the field of household water purification, and relates to a compound integrated structure of various filter materials, in particular to a composite filter element assembly with one end of the nozzle integrated and its matching installation head Background technique [0002] At present, most of household water filtration adopts pre-coarse filtration, membrane fine filtration and post-filtration to improve taste. However, to complete the filtration of so many filter materials, the previous water purifier needs to install multiple filter elements, and each filter element is loaded with different filter materials to complete the above-mentioned filtration and obtain drinking water with a high-quality taste. The volume occupied by the household water purifier is quite large, resulting in a large volume of the water purifier, which brings a lot of inconvenience in the use of the family. At present, the small-volume water purifier is ...

Problems solved by technology

However, to complete the filtration of so many filter materials, the previous water purifier needs to install multiple filter elements, and each filter element is loaded with different filter materials to complete the above-mentioned filtration and obtain drinking water with a high-quality taste. The volume occupied by the household water purifier is quite large, resulting in a large volume of the water purifier, which brings a lot of inconvenience in the use of the family. At present, the small-volume water purifier is more and more recognized and favored by the market, so The components of the water purifier need to be integrated and modularized. The integration and modularization of the filter element mainly use the composite of multi-stage filter materials of the filter element.

[0003] Most of the current composite filter elements in the market combine the two steps of filtration into one filter element, but to complete the above-mentioned precision filtration, more than one filter element is still required, and few can complete the filtration of all steps in one filter element, even if Yes, all the water inlets and outlets cannot be integrated at one end of the filter element, which makes it very inconvenient to install and disassemble the filter element
