Patent ID: 8444852

Claim:
A magnetic water activator comprising: a pair of magnetic circuit constituting members made of a high magnetic permeability material, respective ends of each of the magnetic circuit constituting members having a hinge connection portion being rotatably connected to each other; permanent magnets arranged along facing surfaces of the magnetic circuit constituting members; and an elastic resin shell having a generally annular shape partially including a slit extending in a radial direction, wherein all of the magnetic circuit constituting members containing the hinge connection portion and the permanent magnets are buried and held in the shell in an airtight state, and wherein when the slit is opened from an unbiased state in which no external force acts upon the shell to an opened state, the shell causes a flexible return force to act on the magnetic circuit constituting members, with the flexible return force facilitating a return from the opened state to the unbiased state.
