[0053] Specifically, the UV sterilization mechanism 3 is a UV sterilizer.

[0054] It should be noted that, in the present embodiment, the first chamber and the second chamber are arranged in parallel, but their orientation is not limited. The first chamber can be arranged on the left side of the second chamber, or behind or in front of the second chamber; the manual pump 24 can also be arranged at the center position of the first filter mechanism 2, and arranged concentrically with the first water purification component 23, ultimately achieving the effect that the first filter mechanism 2 and the second filter mechanism 4 are adjacent to each other and arranged as an integrated whole.

[0055] like Figure 2 As shown, a first valve seat for installing a high-pressure valve 25 and a water suction valve 26 is provided in the water inlet of the first filter mechanism 2 and at the bottom of the barrier 22 . The water suction valve 26 is closer to the water inlet of the first filter mechanism 2 than the high-pressure valve 25 .

[0059] Among them, nanocluster metal filter materials have a wide range of uses, mainly including the following aspects:

[0060] Drinking water purification: It can effectively remove residual chlorine, lead, cadmium, chromium, arsenic and other heavy metal ions in water, reduce the concentration of organic micropollutants, inhibit and kill bacteria, and provide better quality and safer drinking water for families, schools, offices, etc.; Industrial wastewater treatment: It can adsorb and catalytically degrade organic pollutants in wastewater, such as dyes, antibiotics, etc., and can also reduce and adsorb some heavy metal ions, which helps to achieve the standard discharge of industrial wastewater and the recycling of water resources.

[0061] Perovskite materials have many uses in water treatment, such as removing heavy metals. Perovskite materials have a special crystal structure and a large number of active sites on their surface, which can interact with heavy metal ions. For example, heavy metal ions such as lead, mercury, and cadmium in water can coordinate with oxygen atoms or metal atoms on the surface of perovskite, and thus be adsorbed on the surface of the material to achieve the purpose of removing heavy metals; adsorbing organic pollutants, and having a good adsorption effect on organic pollutants in water, such as dye molecules, pesticide residues, and polycyclic aromatic hydrocarbons. The adsorption principle is mainly to fix organic pollutants on the surface of the material through intermolecular forces, hydrogen bonds, etc., to reduce the content of organic pollutants in water; photocatalytic degradation of pollutants and decomposition of organic pollutants: under light conditions, perovskite materials can generate electron-hole pairs, which have strong redox ability. They can react with organic pollutants in water to decompose complex organic molecules into carbon dioxide, water, and harmless small molecules. For example, perovskite materials can effectively degrade dye pollutants such as methyl orange in water under the irradiation of visible light; killing microorganisms, the active oxygen species produced during the photocatalytic process, such as hydroxyl radicals and superoxide radicals, have strong bactericidal ability. These active oxygen species can destroy the cell walls, cell membranes and internal biomacromolecules of microorganisms, thereby achieving the effect of killing microorganisms such as bacteria, viruses and algae in water; filtering and separation, physical interception, perovskite materials can be made into filter materials with a certain pore structure to physically intercept impurities such as suspended particles and colloids in water. For example, perovskite is made into a membrane material. During the water treatment process, impurity particles larger than the membrane pore size cannot pass through the membrane, thereby achieving the separation of water and impurities.
