Abstract

The invention provides a water purifier comprising a control valve for controlling flowing of water flow and a filtration device for purifying raw water, the filtration device comprises a shell, a primary filtration core and a secondary filtration core, and the shell forms a first accommodation cavity; the primary filtration core and the secondary filtration core are both arranged in the first accommodating cavity of the shell, the shell and the primary filtration core form a raw water channel located between the shell and the primary filtration core, the primary filtration core and the secondary filtration core form a purified water channel located between the primary filtration core and the secondary filtration core, and the secondary filtration core has a purified water outlet. The filtration device is provided with a first communicating opening, a second communicating opening and a third communicating opening, and the control valve comprises a valve body and a valve core. A valve cavity, a first opening, a second opening, a third opening, a fourth opening, a fifth opening, a raw water inlet and a sewage discharge opening are formed in the valve body.

Description

technical field [0001] The invention relates to a water purifier, in particular to a water purifier capable of performing two-stage purification on raw water (or tap water). Further, the water purifier of the present invention can also control the raw water to backwash the primary filter element. Background technique [0002] With the improvement of people's living standards and the increasing emphasis on health, people's requirements for the quality of domestic water are also getting higher and higher. However, on the other hand, in many countries, especially developing countries, with the continuous development of industry and agriculture, the problem of water pollution is becoming more and more serious, which will inevitably lead to the water sources of domestic water, especially the water sources of tap water, being severely or slightly or heavy impact. In addition, the water quality of tap water will also be affected by the external environment and water supply pipeli...
