ABSTRACT:
A water activation device is configured by arranging a plurality of water activation pieces in a holder in a manner that the water activation pieces do not contact with each other where an axial direction of each piece is established along the flow passage. Multiple layers of the holders are established in an internal space of the body of the water activation device. Each of the water activation piece is formed as a cylindrical body with a through hole that includes an axis. Spiral grooves are formed non-continuously or continuously on an inner surface and outer surface of the water activation piece so that when the axis of the water activation piece is established in the flow passage, the water activation piece axially rotates by the flow pressure. The spiral grooves are formed in a rightward rotation (clock-wise) manner in plan view.
