▎ 摘　　要

NOVELTY - Water purifying filter core comprises filter shell (1), activated carbon particles (2), graphene microparticles (3), cover (4), upper sponge leak-proof plug (5) and lower sponge leak-proof plug (6). The filter shell is provided with sponge leak-proof plug. A mixture of graphene microparticles and activated carbon particles is arranged in the filter shell. USE - Water purifying filter core. ADVANTAGE - The device absorbs more impurities; and has better water purifying effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of water purifying filter core comprising crushing graphene into fluffy powder, mixing graphene microparticles and activated carbon particles, taking filter shell, adding mixed material and installing the other components of the water filter. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structure of water purifying filter core. Filter shell (1) Activated carbon particles (2) Graphene microparticles (3) Cover (4) Upper sponge leak-proof plug (5) Lower sponge leak-proof plug (6)
