WATER PURIFIER

PURPOSE:To efficiently purify water,by providing an ozonizer below the exhaust opening of a pump for sending pressurized air, an air feed opening below the ozonizer and an air feed pipe extended above a water tank and immersed in water inside the water tank. CONSTITUTION:A power source is supplied to a motor 9 and an oscillating circuit 7, electric power is supplied from said oscillating circuit 7 through a booster circuit 8 to an ozonizer 18, and ozone is formed by silent discharge. The formed ozone is sent from a lower chamber 19 through an air feed opening 20 and an air feed pipe 21 to a microfilter 23 and then discharged in water inside a water tank 22. Hereon, said ozone is sent through the air feed pipe 21 at a position higher than the level of water on the way, so that the backflow of water inside the water tank 22 toward the chamber 3 is effectively inhibited. Foul-smelling substance is decomposed by the oxidizing action of said ozone inside the water tank 22, and the purified water is let overflow through a faucet 24 for reuse.
