A water activation apparatus 1 as a liquid activation apparatus has an electrically conductive inner cylindrical body 20, an electrically conductive inlet connecting pipe 23 connected to the inner cylindrical body 20, an electrically conductive outlet connecting pipe 24 connected to the inner cylindrical body 20, an electrically conductive outer cylindrical body 22 disposed outside of the inner cylindrical body 20 and being electrically isolated from the inner cylindrical body 20, the inlet connecting pipe 23, and the outlet connecting pipe 24, a corrugated pipe 51 disposed inside of the inner cylindrical body 20, a honeycomb mesh portion 52 disposed inside of the corrugated pipe 51, and a plurality of liquid activation ball members 53 filled radially inward of the honeycomb mesh portion 52.

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.

The water activation device includes a conductive body having an in-flow opening and an out-flow opening, a cover member that coats the outer perimeter of the body through insulation material and is insulated from water pipes, and activation material unit formed in a small block containing minerals as a main component. The activation material units are held in a retainer of a holder without contacting with one another, and multiple holders are placed along the same straight line in the direction of the flow in the internal space of the body. Further, the outside of holder is fitted with an inner surface of the internal space so that water can flow through the multiple flow openings formed on the retainer.
