Abstract: Disclosed is a preparation method of weakly basic, ionized, mineralized and healthy drinking water including purifying the tap water by precipitation, filtration and other conventional methods to obtain clean water; and getting the said clean water through reverse osmosis (RO) membrane to obtain RO pure water; heating the said RO pure water to 35-100 degrees celsius by magnetic oscillation or by heating, and then making the RO pure water through weak alkaline, ionized, and mineralization composition, and then filtering the RO pure water by coconut carbon cartridge and PP cotton filter element in turn. The water prepared by the method of the present invention is beneficial to the health of human body and suitable for long-term consumption.

Abstract: A reverse osmosis negative-ion water dispenser comprising a polypropylene filter element, a granular active carbon filter element and a compressed active carbon filter element inside a housing; a low pressure switch, a booster pump, an inlet solenoid valve, an RO filter bottle, an RO membrane and two water outlets for concentrated water and pure water respectively are also provided, wherein the water outlet for concentrated water is connected with a flush solenoid valve and a waste water proportioner assembly, the water outlet for pure water is connected with a storage tank through a high pressure switch and a float switch; the storage tank is provided with a high-low level three-line water level switch and connected to a combined hot and cold exchange tank. A negative-ion generating device comprising a solenoid valve, a fast heating equipment and a negative-ion filter device is provided to generate negative-ion.
