The invention discloses a reverse osmosis membrane filter element with a new flow channel structure. The reverse osmosis membrane filter element comprises a central tube and a reverse osmosis membranemodule, and the reverse osmosis membrane module wraps the outer side of the central tube; a raw water flow channel is formed in the reverse osmosis membrane module, a dilution flow channel is formedin the raw water flow channel, a water inlet of the dilution flow channel is formed in the water inlet end of the raw water flow channel, a water outlet of the dilution flow channel is formed in the tail end of the raw water flow channel, and raw water flows in from the water inlet of the dilution flow channel, flows along the dilution flow channel and flows out from the water outlet of the dilution flow channel so as to dilute concentrated water at the tail end of the raw water flow channel. The invention further discloses a reverse osmosis water purifier using the reverse osmosis membrane filter element with the new flow channel structure. The reverse osmosis membrane filter element with the new flow channel structure has the advantages that by additionally forming the new flow channel in the raw water flow channel, the TDS of concentrated water at the outlet end of the filter element can be lowered by dilution, scaling can be delayed, and the service life of the filter element can be prolonged.
Description
technical field [0001] The invention relates to the technical field of home appliances, in particular to a reverse osmosis membrane filter element and a reverse osmosis water purifier with a new channel structure. Background technique [0002] With the improvement of people's requirements for drinking water quality, pure water systems are gradually entering the drinking water system of every household. The water purifiers currently on the market generally use reverse osmosis membrane filters, which can filter organic matter, colloids, bacteria, viruses and other impurities in raw water, especially for inorganic salts, heavy metal ions and other impurities. efficiency. Therefore, the reverse osmosis membrane filter element constitutes the core component of the water purifier, and the filtration effect of the water purifier is directly related to the filtration effect of the reverse osmosis membrane filter element. [0003] There are many problems in the use of existing reve...
