Reverse osmosis filter and water purifier

Abstract

This application involves a reverse osmosis filter element and water purifier. The reverse osmosis filter element includes: filter bottle, which is opened with raw water imports, pure water exports and wastewater exports;Outside the water pipe, the interval between the inner surface and the outer surface of the original water pipe to form a diversion space; the reverse osmosis membrane component, including the reverse osmosis membrane unit, head cover and tail cover that is wrapped in the central pipe,The cavity formed between the outer surface and the inner surface of the filter bottle to store pure water, and the empty cavity and pure water exit are connected; the tail surface of the tail cover and the reverse osmosis membrane unit has the first gap.Enter the membrane layer of the reverse osmosis membrane unit; the pure water flow tract of the reverse osmosis membrane unit is connected to the diversion space. There is a pure water channel on the head cover. One end of the pure water channel is connected to the diversion space, and the other end is connected to the empty cavity.The reverse osmosis filter element provided by the present invention is prolonged.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a reverse osmosis filter element and a water purifier using the reverse osmosis filter element. Background technique [0002] At present, the reverse osmosis water purifier on the market, the main functional component is the reverse osmosis filter element. A reverse osmosis filter element usually includes a central tube and a reverse osmosis membrane unit wound on the central tube. Among them, the reverse osmosis membrane unit is formed by folding and sealing the reverse osmosis membrane to form independent raw water flow channels and pure water flow channels. The raw water is passed into the membrane layer of the reverse osmosis membrane unit, enters the raw water flow channel, and enters the pure water flow channel after being filtered and purified by the reverse osmosis membrane. One side of the reverse osmosis membrane is pure water and the other side i...

Problems solved by technology

[0003] After the water purifier is shut down for a certain period of time, the salt ions on the concentrated water side of the membrane layer of the reverse osmosis filter are generally unable to be removed. Due to the high concentration of salt ions, they will permeate to the pure water side, resulting in the first cup after a long shutdown. The TDS of pure water (Total dissolved solids, abbreviated as TDS, which is called "total dissolved solids" in Chinese) is too high, and it will cause reverse osmosis membrane pollution and reduce the service life of the reverse osmosis filter element
