Fresh water treatment machine

Abstract

The invention relates to the water treatment industry, in particular to the deep filtration and purification aspects of drinking water. The invention discloses a fresh water treatment machine comprising a backflushing filter element, an engine base with a water inlet and a water outlet, a water path switcher and a sealing cover which contacts and is matched with the engine base to form a sealed inner cavity, the built-in water path switcher is provided with a hollow rotating shaft, one end of the hollow rotating shaft is hermetically communicated with a switching water nozzle of a rotary disc of the hollow rotating shaft, the other end of the hollow rotating shaft penetrates through a shaft via hole to form a rotatable water nozzle pipeline, another switching water nozzle of the rotary disc is communicated with another water nozzle pipeline of the engine base through the inner cavity, a fixed disc of the water path switcher is provided with 2-15 water nozzles which correspond to the water nozzles of the rotary disc, are arranged at isotonic included angles as units, correspondingly connected with 1-7 filter elements and form a filter channel, the fixed disc contacts and is matched with the rotary disc, only the water inlet and the water outlet are communicated, and the hollow rotating shaft drives the rotary disc to rotate a switching position by using each isotonic included angle as a unit and form a backflushing channel of the backflushing filter element.

Description

[0001] Prior application name: Water purifier Prior application number: 200910170798.3 Technical field [0002] The present invention is related to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0003] At present, the use of water purifiers has become more popular in China. When using water, a water purifier is used to deeply filter the impurities in the water and the water pipeline, which better protects the health of users. However, with the promotion of water purifiers, their application defects and deficiencies have gradually been exposed. After the filter element of the water purifier has been used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decrease in filtration and adsorption effects. Moreover, as the filter element intercepts more and more impur...

Problems solved by technology

In addition, in view of the characteristics of cleaning and replacing the filter element of the water purifier, the machine needs to be moved frequently, so the machine needs to reserve a certain length of hose in advance and place it on the rear side of the machine, which not only affects the overall cleanliness and beauty of the machine, but also easily causes hose contamination

Above-mentioned defect and deficiency have influenced the popularization of water purifier
