Problems solved by technology

When the user uses water again, the TDS value of the first glass of water is much higher than the TDS value of the normal outlet water, which affects the filtering effect and water quality, and affects the user experience
And because the TDS value of the raw water side is too high, it will cause c

Abstract

The invention relates to a waterway structure for reducing a TDS value of a raw water side of an RO membrane filter element. The waterway structure comprises a rear filter assembly, an RO membrane filter element, a first one-way valve and a second one-way valve. A pure water outlet of the RO membrane filter element is communicated with a water inlet of the first one-way valve, a water outlet of the first one-way valve is communicated with a water inlet of a water inlet flow channel of the rear filter assembly, a water outlet of a water outlet flow channel of the rear filter assembly is communicated with a water inlet of the second one-way valve, and a water outlet of the second one-way valve is communicated with a water inlet of the RO membrane filter element. The waterway structure has the advantages that the structure is simple and compact, pure water flows back to the raw water side of the RO membrane filter element by adjusting the one-way valve, the TDS value of the raw water sideis reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a waterway structure for reducing the TDS value of the raw water side of an RO membrane filter element. Background technique [0002] At present, in the existing household reverse osmosis (RO membrane) and nanofiltration (NF) water purifiers, the RO / NF filter element is a semi-permeable membrane, the TDS value of the raw water side will be high, and the TDS value of the pure water side will be low. When working, by pressurizing the raw water side, the water on the raw water side with high TDS value is reversely osmosis into the pure water side with low TDS value; when the machine is shut down, the pressure on the raw water side will decrease, and the TDS value on the pure water side will gradually decrease under osmosis. becomes higher; after a period of shutdown, the TDS value on the pure water side will become much higher than that during normal operation. When the user uses water again, the TDS value of the first glass of w...
