Large-flux reverse osmosis water purification mechanism for improving water quality of first cup of water

Abstract

The invention relates to the technical field of water purification, and discloses a high-flux reverse osmosis water purification mechanism for improving the water quality of the first cup of water. The mechanism comprises a front filter element, a water inlet valve, a booster pump, a small membrane, a switching valve, a second flow-limiting valve, a concentrated water valve, a large membrane, a first one-way valve and a rear filter element, wherein the front filter element is communicated with the booster pump through the water inlet valve, the booster pump is communicated with the small membrane, and the front filter element is communicated with a tap water feeding pipeline; the small membrane is communicated with the large membrane and the second flow-limiting valve through the switching valve, the second flow-limiting valve is communicated with the concentrated water valve through a pipeline, and the concentrated water valve is communicated with the large membrane through a pipeline. The principle is simple, and batch production is easy to achieve; the quality of water in the first cup of the high-flux reverse osmosis water purifier is improved, namely, the user experience is improved; high-speed water flow on the concentrated water sides of a pure water washing membrane and the small membrane is beneficial to prolonging the service lifetime of the membrane; the washing frequency can be reduced by washing the membrane with pure water, and meanwhile, the process of small membrane concentrated water backflow and serial membrane filter element connection is beneficial to reducing the discharge of concentrated water and is convenient to save water sources to the maximum extent.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a large-flux reverse osmosis water purification mechanism for improving the water quality of head cup water. Background technique [0002] Since the reverse osmosis water purifier was introduced into the country, it has been widely welcomed by people due to its superiority in treating tap water. In recent years, due to the large flow characteristics of drinking and making on-the-spot, the user experience of the water purifier has been improved, and the large-flux reverse osmosis water purifier has been highly appreciated by people. [0003] Most of the large-flux reverse osmosis water purifiers currently on the market are based on the original reverse osmosis water purification process. high flow pump. This process does meet the flow requirements of large-flux water purifiers, but its disadvantage is that when the machine stops water production, due to the disappearance of the...
