Domestic water filtering and purifying structure

Abstract

The invention discloses a domestic water filtering and purifying structure, which comprises a hollow cylindrical filtering shell and at least one filtering unit, wherein the at least one filtering unit is arranged at the inner side of the filtering shell and is further arranged in a superposition manner along the vertical direction; the top of the filtering shell is provided with a water inlet; the bottom of the filtering shell is provided with a water outlet; each filtering unit comprises a filtering upper cover and a filtering base respectively; each filtering upper cover is provided with an umbelliform upper filtering surface; each upper filtering surface is provided with a filtering material which is used for adsorbing and filtering out impurities in water; the outer side edge of the circumference of the filtering upper cover is provided with a water outlet hole; each filtering base is arranged below the corresponding filtering upper cover and is further provided with an inverted umbelliform lower filtering surface; each lower filtering surface is provided with a filtering material which is used for adsorbing and filtering out the impurities in the water; the middle part of each filtering base is provided with a water outlet. By adopting the technical scheme, according to the domestic water filtering and purifying structure, the increment of water filtering time is realized through the oblique filtering surfaces provided with the filtering materials; the domestic water filtering and purifying structure is excellent in filtering effect; further, a filtering structure can be repeatedly used after being cleaned.

Description

technical field [0001] The invention relates to a household filtering water purification structure, in particular to a water filtering structure with long filtering time, good filtering effect, repeated use, quick replacement and convenient cleaning. Background technique [0002] Most of the existing water filtration adopts single-layer or overlapping multi-layer filter layers. Water enters the filter structure in a vertical direction from top to bottom, and then the filter layer absorbs the impurities in the water layer by layer, so as to achieve a fixed standard of water; And this layer-by-layer adsorption vertical filter structure realized by the gravity of water itself has a short filter time, which leads to poor filter effect. At the same time, the airborne increase of the filter holes in the filter layer after long-term use also reduces the filter effect; On the other hand, the filter layer is used to filter the impurities in the water through adsorption, and most of t...
