▎ 摘　　要

NOVELTY - Wrap-around graphene filtering choke comprises inner ring part and outer ring part and the inner ring part comprises multiple groups of first coil. Multiple groups of first coil are connected end to end form parallel closely surrounding to form a hollow tubular structure. a first set of first coil leads out input end. The last group of the first coil lead inner ring connection end. The outer ring part comprises a plurality of sets of second coil. Each group of the second coil is along the outer surface of the tube structure around to the other end of the pipe-shaped structure from the tubular structure one end and passing the hollow inner surface returns to the starting end. A plurality of sets of second coil is connected end to end form the inner outer surface of tube-shaped structure. The first group of second coil is leading outer ring connecting end. USE - Used as wrap-around graphene filtering choke. DETAILED DESCRIPTION - Wrap-around graphene filtering choke comprises inner ring part and outer ring part and the inner ring part comprises multiple groups of first coil. Multiple groups of first coil are connected end to end form parallel closely surrounding to form a hollow tubular structure. a first set of first coil leads out input end. The last group of the first coil lead inner ring connection end. The outer ring part comprises a plurality of sets of second coil. Each group of the second coil is along the outer surface of the tube structure around to the other end of the pipe-shaped structure from the tubular structure one end and passing the hollow inner surface returns to the starting end. A plurality of sets of second coil is connected end to end form the inner outer surface of tube-shaped structure. The first group of second coil is leading outer ring connecting end. The last group of second coil leading-out output end. The inner ring connection end connecting end is connected with the outer ring. The input end is inputting the filtered current. The output end outputs filtered current. The multiple groups of first coil and multiple groups of second coil consisting of a choke ring are formed by a wire. The wire surface is uniformly filled with a filter layer. An INDEPENDENT CLAIM is also included for fabricating wraparound graphene filter choke comprises (i) taking one end of the wire taken as an input end, and forming the other end in a counterclockwise direction to form a circular first coil, (ii) forming a plurality of sets of first coils around the plurality of turns, and enclosing the plurality of sets of first coils to form a tubular inner ring portion, and the centers of the first coils of each group are all on the same straight line, (iii) completing the first coil, the wire extends clockwise toward the outer wall of the tubular inner ring portion, and is wound from one end of the tubular inner ring portion to the other end, and passes through the hollow inner wall of the tubular inner ring portion, wrap around to form a second coil, and (iv) in a counterclockwise direction, continuously surrounding the inner and outer walls of the tubular inner ring portion by the wire, forming a plurality of sets of second coils, and evenly enclosing the plurality of sets of second coils on the tubular inner ring portion, and the last one second coil of the group leads the wire as an output. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the wrap-around graphene filtering choke.
