The atomizer core not only provides a uniform heating ability and a stable operation but also enhance the atomization rate of the fluid to maintain the real and better smoking taste. The atomizer core has a prolonged service life span and an enlarged heating area to reduce the carbon deposits of the atomizer. ## Claims ### Claim 1 An atomizer, comprising: a fluid storage for storing fluid to be atomized; an atomizer core disposed in said fluid storage, wherein said atomizer core comprises a heating element having mesh structure, a fluid absorbing element evenly wrapping around said heating element delivering the fluid to said heating element, and two conductive wires electrically extended from two sides of said heating element respectively; an inhaling mouthpiece coupled on top of said fluid storage, a fluid guiding member, wherein said fluid absorbing element is sleeved in said fluid guiding member; and a supporting member provided at bottom sides of said fluid guiding member and said fluid absorbing element when said fluid absorbing element is received in said fluid guiding member, wherein said supporting member has a vent tube coaxially extended at a center axis of said supporting member, a threaded through hole formed between an inner wall of said supporting member and said vent tube for said conductive wires passing through said threaded through slot, and a glue groove provided at an end of said threaded through slot for encapsulating said conductive wires when glue is applied at said glue groove, wherein said heating element is constructed to have a plurality of mesh wires interlaced with each other to define a plurality of mesh holes for enlarging a heating area to atomize the fluid so as to produce vapor particles, and said fluid absorbing element is made of multiple layers of cotton and is overlappingly wrapped around said atomizer core. ### Claim 2 (depends on 1) The atomizer, as recited in claim 1, wherein said fluid guiding member has two opposite fluid guiding grooves formed at a sidewall of said corresponding to said fluid absorbing element, and a fluid guiding window formed on said sidewall of said fluid guiding member between said fluid guiding grooves to communicate with said fluid absorbing element, wherein each of said fluid guiding grooves has a downward opening. ### Claim 3 (depends on 1) The atomizer, as recited in claim 1, further comprising: a tubular fluid retainer, wherein said fluid storage is formed as a fluid storage medium being loaded in said tubular fluid retainer; two sealing elements, wherein top and bottom openings of said tubular fluid retainer are sealed by said sealing elements respectively to seal said atomizer core and said fluid storage medium in said tubular fluid retainer; and a vent tube extended from said top side of the atomizer core to communicate with said inhaling mouthpiece through one of said sealing elements. ### Claim 4 (depends on 3) The atomizer, as recited in claim 3, wherein said fluid storage medium has a predetermined elasticity and is made of a material that is adapted to absorb the fluid. ### Claim 5 (depends on 3) The atomizer, as recited in claim 3, wherein each of said sealing members has a center through hole, wherein a center air inlet of said inhaling mouthpiece is coupled and sealed at said center through hole of one of said sealing element to couple with said vent tube, wherein said conductive wires of said atomizer core are sealed and extended through said center through hole of another said sealing element. ### Claim 6 (depends on 3) The atomizer, as recited in claim 3, further comprising a battery, a controller, and an end cover are orderly and operatively arranged under said atomizer core, wherein said inhaling mouthpiece and said end cover are press-fitted and tightly affixed at two ends of said housing to form an integrated atomizer. ### Claim 7 (depends on 1) The atomizer, as recited in claim 1, further comprising: a tubular casing having a central through slot, wherein said atomizer core is sleeved within said casing at the central through slot thereof; a second fluid absorbing element provided between said atomizer core and said casing at a position that said second fluid absorbing element is wrapped around said atomizer core; and a sealing element having an inner hole for a bottom of said atomizer core passing through, wherein a mouthpiece cavity of said inhaling mouthpiece, said atomizer core and said bottom of said casing are sealed by said sealing element. ### Claim 8 (depends on 7) The atomizer, as recited in claim 7, wherein said mouthpiece cavity of said inhaling mouthpiece is made of transparent material for enabling the fluid in said fluid storage to be seen through. ### Claim 9 (depends on 7) The atomizer, as recited in claim 7, wherein said casing has a plurality of fluid inlets spacedly formed at a sidewall of said casing to communicate with said second fluid absorbing element. ### Claim 10 (depends on 7) The atomizer, as recited in claim 7, further comprising a battery, a controller, and an end cover are orderly and operatively arranged under said atomizer core, wherein said inhaling mouthpiece and said end cover are press-fitted and tightly affixed at two ends of said housing to form an integrated atomizer.
