Title: Magnetic water activation device
Inventor: NODA KYOICHI
IPC: C02F1/28
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To improve magnetic water activation effect and to reduce the exchange work of a filter member, with respect to a magnetic water activation device where the liquid of running water is made to pass through a cartridge and water liquid is magnetically activated by a magnet for water activation, which is installed in the cartridge. SOLUTION: In the magnet holder sets 1 of a first stage and a third stage, the clockwise lines of magnetic force are generated in parallel to a base board 11. In the magnet holder sets 1 of a second stage and a fourth stage, the counterclockwise lines of magnetic force are generated. When water passes through the holes of the respective magnet holder sets 1, the lines of magnetic force, which are generated by the magnet holder sets 1, can be made to cross so as to be almost orthogonal to the flowing direction of water and effective magnetic water activation is performed. Since the line of magnetic force, which is almost parallel to a direction where water usually flows by t he S-pole and the N-pole of the magnets 13 in the adjacent stages is also generated, effective magnetic water activation is applied on passing water disordered in direction.
