Patent ID: 8398863

Claim:
A water-purifying apparatus for generating anions, the water-purifying apparatus comprising: an anion generator having an inflow pipe formed in a zigzag form, for introducing raw water supplied from a water tap, and a number of rotating units, wherein the number of rotating units comprises a first rotating unit rotatable in a first direction, and a second rotating unit rotatable in a second direction that is different from the first direction, wherein coupling pins are fitted into the inside of the inflow pipe, wherein rotating fins are radially formed on the outer side of the respective rotating units, wherein the rotating units are rotatable by a flow of the introduced raw water to generate bubbles and increase an amount of dissolved oxygen and simultaneously produce anions; a support pipe whose inner portion is empty to accommodate the anion generator in which water pipes are connected with both ends of the support pipe, respectively; and filter portions for preventing the anion generator from moving, said filter portions respectively provided at both ends of the support pipe to filter the raw water.
