Multistage filter element group of water purifier

Abstract

The invention discloses a multistage filter element group of a water purifier. The multistage filter element group of the water purifier comprises a top plate, a bottom plate and a sleeve connected between the top plate and the bottom plate, a filter cartridge assembly is also arranged between the top plate and the bottom plate, the filter cartridge assembly has multiple stages and is annularly arranged at the outer side of the sleeve, and the multiple stages of filter cartridge assemblies are mutually connected in series. The filter cartridge assembly is annularly arranged, so the filter element group is compact in structure and small in size, and saves space; the filter cartridge assembly can rotate circumferentially, so that the filter cartridge assembly needing to be replaced can be rotated to an access hole or an access door of the water purifier as required, a purifier shell does not need to be integrally disassembled, assembling, disassembling and overhauling are extremely convenient, and pipeline wiring is simple and direct; the filter cartridge assemblies are pressed and sealed in an up-down pressing mode, so connection of the filter cartridge assemblies is convenient, anddisassembling is convenient; and the multiple filter cartridge assemblies are connected in series, and the filter elements can be arranged according to needs, so the overall filtering effect is improved.

Description

technical field [0001] The invention relates to a filter assembly, which belongs to the technical field of water purification equipment; in particular, it relates to a multi-stage filter element group of a water purifier. Background technique [0002] Water purifiers are also called water purifiers and water quality purifiers. They are water treatment equipment that perform deep filtration and purification treatment of water quality according to the requirements for water use. They can filter floating objects, heavy metals, bacteria, viruses, residual chlorine, and mud in water. Sand, rust, microorganisms, etc. The water purifier usually referred to generally refers to a small purifier for household use. [0003] Purifier filter components generally use multi-stage filtration to achieve different filtration functions, which makes the purifier: 1. Due to the use of multi-stage filtration, the structure of the purifier or the internal filter element is relatively large, and t...
