Water purifier

Abstract

The invention relates to a water purifier. The water purifier comprises a ventilation impermeable shell formed by bonding aggregate particles and hydrophobic binders, wherein the ventilation impermeable shell has holes through which gas molecules formed between the adjacent aggregate particles can pass while liquid water molecules cannot pass; the aperture of the holes ranges from 0.001mm to 0.3mm; a raw water inlet is arranged on the top of the ventilation impermeable shell; the inside of the ventilation impermeable shell is horizontally provided with a filtering and purifying layer; and the lower part of the ventilation impermeable shell is provided with a purified water outlet communicated with a purified water storage cabin. According to the water purifier, the ventilation impermeable shell is used, and when the raw water inlet is closed and the water purifier is totally closed, the outside air can enter the water purifier through the holes of the ventilation impermeable shell instead of entering the water purifier through the purified water outlet, so that secondary pollution of the purified water caused by water-air exchange between the outside air and the purified water is avoided.

Description

technical field [0001] The invention relates to a water purifier and belongs to the technical field of drinking water purification treatment devices. Background technique [0002] At present, the drinking water in most urban areas in my country is tap water supplied centrally. Usually, the tap water has been purified by the water company before it is delivered to the user and has reached the national drinking water standard. However, the tap water must be delivered to the user. Through multiple metal or plastic pipes, harmful substances such as bacteria and heavy metals in the pipes will dissolve into the water, resulting in secondary pollution of tap water; in addition, in rural areas where centralized water supply has not been realized, most households directly draw groundwater or surface water Natural water is used as drinking water, and these waters usually contain harmful substances such as a large amount of suspended solids and bacteria due to surface environment polluti...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that if the water purifier in the prior art is installed in a sealed manner, there will be a problem of "water-air exchange" causing the purified water to be polluted twice. If vent holes are opened to avoid "water-air exchange", then There is a problem that water leaks easily and pollutes the indoor environment, so as to provide a water purifier that is breathable, water-tight, and can avoid "water-air exchange"

[0007] And aiming at the problem of inconvenient replacement of filter layer materials caused by integral filling of various filter layer materials in the water purifier in the prior art, a water purifier with convenient filter layer material replacement is provided
