DETAILED DESCRIPTION
[0067] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0068] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0069] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.
[0070] The implementation principle of this embodiment is to use ultrafiltration membrane 20 technology as the core and a simple green physical separation technology. The pore size of the ultrafiltration membrane 20 is between 10-100nm. During the water purification process, the ultrafiltration membrane 20 uses the pressure difference on both sides of the membrane as the driving force. The ultrafiltration membrane 20 is used as the filtering medium. Under a certain pressure, when raw water flows through the membrane surface, the densely distributed nanopores on the surface of the ultrafiltration membrane 20 only allow water and small molecules to pass through to become purified water, while substances in the raw water that are larger than the membrane pore size are retained on the water inlet side of the membrane, thereby achieving purification of the raw water and obtaining qualified drinking water for daily use.
