Patent ID: 7094342

Claim:
A water activation device, comprising: a body which is made of conductive material and has an in-flow opening and an out-flow opening; a cover member which is made of conductive material and covers an outer surface of the body through insulation material therebetween and is insulated from water pipes; a plurality of holders overlapped with one another in an axial direction of the body, each of the holders being formed of a retainer having a plurality of flow openings; and a plurality of activation material units each having a cylindrical shape and containing minerals as a main component; wherein two or more activation material units are placed in the retainer of each holder without contacting with one another so that the plurality of activation material units are overlapped through the holders in the axial direction of the body; and wherein the plurality of flow openings have slope surfaces tilted toward inner and outer directions, thereby producing turbulent flows of the water when the water flows through the flow openings.
