Abstract

The invention discloses a water purifier, the water purifier is provided with a water source inlet and a water outlet, the water purifier comprises a first filter element, a second filter element and a regulating valve, the first filter element comprises a pretreatment unit and a first membrane unit, a water inlet of the pretreatment unit is communicated with the water source inlet, and a water outlet of the first membrane unit is communicated with the water outlet. A water inlet of the first membrane unit is communicated with a water outlet of the pretreatment unit, and a pure water port of the first membrane unit is communicated with the pure water outlet; the second filter element comprises a second membrane unit, a water inlet of the second membrane unit is communicated with the water outlet of the pretreatment unit, and a pure water port of the second membrane unit is communicated with the pure water outlet; the regulating valve is used for independently regulating the pure water outlet flow of the first membrane unit or independently regulating the pure water outlet flow of the second membrane unit. The water purifier widens the desalinization rate range of the effluent quality, so that the requirements of users on different water qualities can be met, and the use experience of the users is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water purifier. Background technique [0002] With the improvement of my country's economy and living standards, people's requirements for drinking water quality are getting higher and higher, and the application of water purifiers in households is becoming more and more common. At present, water purifiers usually use a single reverse osmosis filter element or a single nanofiltration filter element, in which the desalination rate of the reverse osmosis membrane is generally as high as 90%-99%, while the desalination rate of the nanofiltration membrane is generally lower than 50%, so As a result, the desalination rate range of the effluent water quality is limited, and the effluent water quality of the water purifier is relatively single, which makes it difficult to meet the needs of users for different water quality, which affects the user's water experience.
