Multistage multi-medium combined water purifier

Abstract

The invention provides a multistage multi-medium combined water purifier, and relates to a water purifier. The water purifier comprises a plurality of filtering units, wherein the filtering units comprise filtering core bodies; a filtering core head assembly is arranged above each the filtering core body; each the filtering core head assembly comprises an upper outer cover and an outer cover baseseat; the upper outer covers are buckled with the upper parts of the outer cover base seats; a connecting water pipe is protruded from the middle position of one side of each the outer cover base seat; a plurality of pawls are arranged on the outer walls of the connecting water pipes; a plurality of connecting bolts are arranged around the connecting water pipes; a water outlet is formed in the middle position of the other side of each the outer cover base seat; a plurality of positioning holes are formed around the water outlets; a plurality of the connecting bolts correspond to the positioning holes of the upper filtering unit; and the connecting water pipe corresponds to the water outlet of the upper filtering unit. The sunk multi-point pawls are used for unidirectionally fastening a quick-connect joint and four-point positioning fasteners are matched, so that the water purifier is firm and practical, has good sealing performance, high reliability, more convenient connection and freer combination, and greatly meets the filtration requirements of vast customers on different water quality in different regions.

Description

technical field [0001] The invention relates to a water purifier, in particular to a multi-stage multi-media combined water purifier. Background technique [0002] China has a vast land and abundant resources, and the water quality varies greatly from east to west, from north to south, and it is difficult to use a single water purifier for a wide range. Even in the same city, the water quality in different regions varies greatly. In the past, users bought a water purifier at will without knowing the local water quality, and ended up using it at home. Because the filter configuration selection is not targeted, the filtering effect will be poor and the water quality will not achieve the desired effect; or the water quality itself is good. , but the configuration of the water machine has too many filtration stages, repeated filtration will consume energy, increase maintenance costs, and cause unnecessary waste. Contents of the invention [0003] The present invention propose...

[0002] China has a vast land and abundant resources, and the water quality varies greatly from east to west, from north to south, and it is difficult to use a single water purifier for a wide range of applications. Even in the same city, the water quality in different regions varies greatly.

In the past, users bought a water purifier at will without knowing the local water quality, and ended up using it at home. Because the filter configuration selection is not targeted, the filtering effect will be poor and the water quality will not achieve the desired effect; or the water quality itself is good. , but the number of filtration stages of the configured water machine is too many, repeated filtration will consume energy, increase maintenance costs, and cause unnecessary waste
