Patent ID: 7981378

Claim:
A water activation device for activating water, comprising: a conductive body having an in-flow opening and an out-flow opening, thereby forming a water flow passage between the in-flow and out-flow openings, a plurality of holders arranged in an internal space of the conductive coating body in a manner of forming a plurality of stages along the water flow passage, a conductive coating body that covers an outer surface of said conductive coating body with an insulation material so that said conductive coating body is insulated from a flow pipe, and a plurality of water activation pieces mounted on said holder of each stage without contacting each other, each water activation piece being formed in a small lump with mineral as a main component in in said holder arranged in said conductive coating body, wherein each of said water activation pieces comprising a column-like body of predetermined length where an axis thereof is arranged along the water flow passage, a through hole formed in said column-like body about said axis, and wherein a plurality of spiral grooves are continuously or non-continuously formed on an inner surface of said through hole and an outside surface of the column-like body, and wherein said water activation pieces at each stage of said holders axially rotate when the spiral grooves on the inner surface of the through hole and the outer surface of the column-like body contact the water flow passage.
