Filtering device for water intake pipe of water purifier

Abstract

The invention discloses a filtering device for a water intake pipe of a water purifier. The filtering device comprises a filtering device body, a running water intake pipe, a wastewater drain pipe anda pure water drain pipe, wherein the diameter of a filtering hole of a first PP (polypropylene) cotton filtering layer is greater than the diameter of a filtering hole of a second PP cotton filteringlayer; the diameter of a particle of a first particle activated carbon filtering layer is greater than the diameter of a particle of a second particle activated carbon filtering layer; a permeating hole of a first permeating film is greater than a permeating hole of a second permeating film. By adopting the structure, the filtering device has the advantages that the impurities can be precisely removed; a circulation water pipe is communicated with a first reverse water permeating film filtering layer and a pressurizing water pump, and a circulation water pump is arranged on the circulation water pipe, so that the impurities in the running water can be cyclically treated multiple times; by arranging four activated carbon sterilizing filtering layers, and fixing ultraviolet light sources atthe upper end and lower end of each activated carbon sterilizing filtering layer, the water can be more precisely disinfected in the use process, and the filtering device is more suitable for realistic life.

Description

technical field [0001] The invention relates to the technical field related to pure water machines, in particular to a filter device for water inlet pipes of pure water machines. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for the purity of drinking water are becoming more and more stringent, so the utilization rate of household pure water machines has generally increased. But the pure water machine that uses at present is generally all directly installed on the faucet, and directly carries out water treatment to the tap water gushed out, and it just simply has the effect of purifying pure water, can not make water increase activity, is suitable for the absorption of human body, and because It uses the pressure of tap water to filter and infiltrate. As time goes by, clogging occurs from time to time. In addition, the filter element has high requirements for water, and the filter element needs to be replace...
