Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1, which is a schematic structural diagram of an embodiment of a reverse osmosis membrane filter element according to the present invention, the reverse osmosis membrane filter element includes a housing 1, and a reverse osmosis membrane element 2, a pure water pipe 3, and a water storage member 4 installed in the housing 1. The reverse osmosis membrane element 2 is coated on the outer wall of the pure water pipe 3 and is used for filtering raw water flowing through, and the two opposite ends of the reverse osmosis membrane element 2 are a raw water inlet end and a waste water outlet end respectively. When water is produced, raw water pressed into the housing 1 by the pressurizing device flows into the reverse osmosis membrane element 2 from the raw water inlet end, after filtration, the produced pure water enters the pure water pipe 3 through the water through holes on the pipe wall of the pure water pipe 3 and is discharged out of the filter element through one end of the pure water pipe 3, and concentrated waste water in the reverse osmosis membrane element 2 is discharged out of the filter element through the waste water discharge end, specifically, refer to the water flow direction indicated by the arrow in fig. 1.
The water storage member 4 has a first water chamber a and a second water chamber B separated by an elastic diaphragm 43, and the sizes of the first water chamber a and the second water chamber B can be adjusted by using the characteristics of elasticity, softness and water impermeability of the elastic diaphragm 43, and in order to realize back flushing by using pure water, the first water chamber a is communicated with the pure water pipe 3, and a water pipe 11 for communicating an external water source with the second water chamber B is provided on the housing 1.
