Abstract

The invention discloses a double-membrane double-water-outlet water filtering and purifying system and a water purifier. The water purifier is used for desalting and purifying water through the double-membrane double-water-outlet water filtering and purifying system; the water filtering and purifying system is provided with a first filtering unit and a second filtering unit; one end of the first filtering unit and one end of the second filtering unit are respectively communicated with a raw water pipeline; the first filtering unit and the second filtering unit are communicated with each otherthrough a water path, the water outlet of the first filtering unit is communicated with a pure water pipeline and a concentrated water pipeline, the water outlet of the second filtering unit is communicated with the pure water pipeline and the concentrated water pipeline, and the desalination rate of the first filtering unit is higher than that of the second filtering unit. Filtration and desalination are carried out through the two filtering units with different desalination rates, and the sequence of raw water entering the different filtering units is controlled through the valves, so that pure water with different water qualities is generated, the water use requirements of users are met, and the use experience of the users is improved.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a double-membrane and double-outlet water filtration and purification system and a water purifier. Background technique [0002] Most reverse osmosis water purifiers use reverse osmosis filter elements for water purification operations, and the reverse osmosis filter elements have reverse osmosis membranes. When the raw water enters the reverse osmosis water purifier, a certain pressure is applied to the water to make the water molecules and ionic mineral elements in the raw water pass through the reverse osmosis membrane, while the macromolecular inorganic salts in the tap water include heavy metal ions, organic matter, bacteria and Viruses cannot pass through the reverse osmosis membrane with small membrane pores to achieve water purification. Existing reverse osmosis membrane water purifiers can only produce a single water quality, that is, pure water for drinking and...
