Reverse osmosis filter core, reverse osmosis water purification system, and reverse osmosis water purifier

Abstract

The invention discloses a reverse osmosis filter core, a reverse osmosis water purification system, and a reverse osmosis water purifier. The reverse osmosis filter core comprises a membrane element and a housing; the membrane element comprises a central pipe assembly, a plurality of reverse osmosis membrane assemblies, a first end cap, and a second end cap; the central pipe assembly comprises a pure water pipe and a plurality of waste water pipes; the plurality of reverse osmosis membrane assemblies are arranged around the central pipe assembly; the first end cap and the second end cap are used for covering the two ends of the plurality of reverse osmosis membrane assemblies and the central pipe assembly; the first end cap is provided with a waste water outlet; the second end cap is provided with a pure water outlet; the housing comprises a bottle body and a cover body; the membrane element is arranged in the housing; the cover body is provided with a waste water chamber; the waste water chamber is communicated with the waste water outlet via sealing connection; the bottle body is provided with a pure water chamber and a raw water chamber; the pure water chamber is communicated with the pure water outlet via sealing connection; the raw water chamber is communicated with a gap between the membrane element and the bottle body. The structure of the cover body of the housing of the reverse osmosis filter core is simplified.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis water purification, in particular to a reverse osmosis filter element, a reverse osmosis water purification system and a reverse osmosis water purifier. Background technique [0002] A reverse osmosis filter element is used in a reverse osmosis water purifier to purify water. The reverse osmosis filter element generally includes a shell and a reverse osmosis membrane element. An existing reverse osmosis membrane element with side flow water feeds raw water, pure water and Waste water is separated, so that the inlet and outlet of raw water, pure water and waste water are all concentrated on the cover of the shell, resulting in a complicated structure at the cover of the shell of the reverse osmosis filter element. Contents of the invention [0003] The main purpose of the present invention is to provide a reverse osmosis filter element, aiming at simplifying the structure at the cover of ...
