It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Please refer to the attached Figure 1 The purpose of this embodiment is to provide a weak alkaline water purifier, comprising: a ceramic inner core filter 2, a first coconut shell activated carbon filter 3, a second coconut shell activated carbon filter 4 and a one-micron cotton filter 5 connected in sequence; wherein, the input end of the ceramic inner core filter 2 is provided with a water inlet switch 1, the output end of the one-micron cotton filter 5 is connected to the first end of the four-way valve pressure switch 6, and the second end of the four-way valve pressure switch 6 is connected to the input ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10; the first output ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 are connected to the third end of the four-way valve pressure switch 6; the second output ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 are connected to the wastewater outlet 19; the fourth end of the four-way valve pressure switch 6 is connected to the water tank 11, and the water tank 11 is connected to the water connection switch 12.

[0023] It should be pointed out that the ceramic inner core filter 2 uses ceramic material as a water treatment device for filtering medium, which is mainly used to remove impurities and pollutants in water. Its core component is a ceramic filter element, which uses the microporous structure of ceramics to intercept suspended matter, particulate matter and some harmful substances such as bacteria in water, so as to achieve the purpose of purifying water quality. The two coconut shell activated carbon filters mainly use the adsorption performance of activated carbon to remove various harmful substances and foreign matter in water. The one-micron cotton filter 5 is a fine filtering device, and its core component is a cotton filter medium, which can effectively filter out particulate matter of one micron and above. The reverse osmosis membrane filter is an efficient water treatment device, and its core lies in the reverse osmosis membrane technology, which uses the selective permeability of a semipermeable membrane to effectively remove impurities such as dissolved salts, colloids, microorganisms, and organic matter in water, so as to obtain pure water. The weakly alkaline water purifier in this embodiment filters impurities and foreign matter in water step by step through the ceramic inner core filter 2, the first coconut shell activated carbon filter 3, the second coconut shell activated carbon filter 4 and the one-micron cotton filter 5 arranged in sequence, thereby improving the purification effect.

[0024] Further, the first output ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 are connected in parallel; the second output ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 are connected in parallel. Multiple reverse osmosis membrane filters are connected in parallel to improve the water purification efficiency. A second wastewater switch 13 and a first wastewater switch 14 are connected in parallel between the second output ends of the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 and the wastewater outlet 19.

[0025] In this embodiment, the water connection switch 12 is an electromagnetic switch or a manual switch. A post-activated carbon filter 17 and a magnetizing device 15 are sequentially arranged between the output end of the water tank 11 and the water connection switch 12. Water molecules will rearrange under the action of the magnetic field to form an orderly molecular structure, thereby changing the physical properties of water such as surface tension, solubility, and conductivity, as well as chemical properties such as oxidation-reduction potential and pH value.

[0026] In addition, a water level switch 18 is provided in the water tank 11. When the water level in the water tank 11 reaches a certain height, each filter stops working. The water tank 11 is also connected to an ozone switch 16. The second wastewater switch 13 and the ozone switch 16 are opened or closed synchronously with the water connection switch 12. It should be noted that when the water connection switch 12 is opened to connect water, the ozone switch 16 is opened to sterilize the water in the water tank 11 with ozone. When the water connection switch 12 is closed, the ozone switch 16 is closed, and ozone sterilization is no longer performed. In this embodiment, when the water connection switch 12 is opened to connect water, due to the decrease in the water level in the water tank 11, the wastewater discharged from the first reverse osmosis membrane filter 7, the second reverse osmosis membrane filter 8, the third reverse osmosis membrane filter 9 and the fourth reverse osmosis membrane filter 10 will increase, and the first wastewater switch 14 cannot effectively discharge the wastewater. At this time, the second wastewater switch 13 will be opened to improve the discharge efficiency of the wastewater and keep the wastewater ratio within a certain range.

[0027] Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model should be included in the protection scope of this utility model.
