Abstract

The invention provides a flow guide used for a filter element assembly, a filter element assembly and a water purifier. There is a height difference between them, and the side wall of the flow guide is between the inner edge of the flow guide and the outer edge of the flow guide. The problem of uneven water flow distribution of the filter element assembly is solved after the flow guide is set, the water flow velocity is optimized, the filtration efficiency is improved, and the life of the filter element is improved.

Description

technical field [0001] The invention relates to the field of water purifiers, in particular to a flow guide applied to a filter element assembly. Background technique [0002] Water purifiers generally include multi-stage filter components, among which PP cotton filter components and activated carbon filter components are indispensable filter components in water purifiers. The current PP cotton filter element is generally a cylindrical ring structure, and the PP cotton filter element generally enters water at the edge and exits in the middle. The raw water inlet of the existing PP cotton filter assembly is generally arranged on one side. The raw water enters the filter element through the water inlet and is filtered by the columnar PP cotton. Sediment and other impurities are blocked outside the PP cotton, and the filtered water enters the PP cotton. The inner center channel is finally pressed out of the filter element upwards from the middle outlet. This structure has cer...
