Magnetizing device for improving purification effect of water filter

The utility model discloses a magnetizing device for improving the purification effect of a water filter. The magnetizing device comprises a pair of symmetrical small container modules, wherein the bottoms of the small container modules are in the shape of semicircular arch bridges, the two symmetrical small container modules form a circular space so as to match with the diameters of different water inlet pipes and close, fix and clamp the water inlet pipe, the surfaces of the symmetrical small container modules are convex, horizontally corresponding parts at the two sides of the small container modules are provided with circular holes of bolts so as to fix and clamp the water inlet pipe, a neodymium-boron magnet and a pure iron are respectively hidden in the two small container modules, and the magnetic poles of the neodymium-boron magnets in the two small container modules oppositely correspond to each other. The magnetizing device has the advantages that formed magnetic force lines are concentrated in the
