Abstract

The invention relates to the water treatment industry, particularly to deep filtration and purification of drinking water, and discloses a fore-laying waterway switching device and a water purifier with the fore-laying waterway switching device. The fore-laying waterway switching device comprises a rotating disc and a fixing disc, wherein the rotating disc and the fixing disc correspond to a fore-laying filtering channel, are in contact fit to form a sealed switching interface, and are arranged in the sealed cavity, the fore-laying waterway switching device further comprises a reverse osmosisfiltering channel, the reverse osmosis filtering channel is connected between the rear end of the fore-laying filtering channel and a water outlet pipeline of a machine seat, a plurality of water ports corresponding to the outer water port, the transition water port and the central water port of the rotating disc are formed in the fixing disc, the number of the water ports in the same circle equant switching position of the fixing disc is smaller than the number of the equant switching positions, the front water port of the fixing disc and the rear water port, closed by the rotating disc, of the fixing disc are respectively connected with the head ends and the tail ends of 1-5 fore-laying filtering liners connected in series, one of the outer water port and the transition water port of therotating disc corresponds to the front water port of the fixing disc, and the other water port is closed by the fixing disc closing and is connected with a back-flushing subsequent pipeline.

Description

[0001] Title of prior application: Front water switch and water purifier equipped with front water switch [0002] Prior application number: 201811211639.9 technical field [0003] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0004] After the filter gall of the water purifier is used for a period of time, the filter material of the filter gall is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. Moreover, as the filter gall retains more and more impurities , often make the "pollution" degree of the filter gall impurities exceed the "pollution" degree of the drinking water itself, so that the filter gall becomes a new "pollution" source. Especially in some water purifiers using ultrafiltration membranes, nanofiltration membranes, and reverse osmosis...
