Electronic cigarette

1. An electronic cigarette comprising a battery container, an outer sleeve connected with the battery container, a battery assembly received in the battery container, an atomizer seat, a glass fiber tube, an atomizer electrode and a heating assembly; the atomizer seat, the glass fiber tube and the atomizer electrode are all received in the outer sleeve; the atomizer electrode defining a first through hole, the atomizer seat defining a second through hole, and the glass fiber tube defining a channel;

wherein the battery container defines at least one air inlet, and a first gap is formed between the atomizer electrode and the battery assembly along an axial direction;

wherein the air inlet communicates with the first gap, and the air inlet, the first gap, the first through hole, the second through hole and the channel form an air flow loop;

wherein, the atomizer seat is a hollow cylinder; an end of the atomizer seat which is opposite to the glass fiber tube is connected to the atomizer electrode, and the other end of the atomizer seat which is opposite to the atomizer electrode engages in the glass fiber tube and connects to the heating assembly to realize an electrical connection between the heating assembly and the atomizer electrode;

wherein the electronic cigarette further includes a supporting member of a hollow cylindrical shape;

wherein the supporting member includes a fixing portion and a sleeve portion being perpendicular to the fixing portion; and

wherein the fixing portion is configured to connect the atomizer seat with the atomizer electrode, and the sleeve portion is received in the second through hole.

2. The electronic cigarette of claim 1 , wherein a second gap is formed between the battery container and the battery assembly;

wherein the battery container is provided with five air inlets, and the air inlets are separated from each other and are located in an axial direction of the battery container equidistantly; some of the air inlets are located in a part of the battery container corresponding to the first gap; the others of the air inlets are located in a part of the battery container corresponding to the second gap;

wherein a width of the first gap is ranged from 0.5 to 10 mm, a width of the second gap is ranged from 0.05 to 7 mm; wherein a cross sectional area of the air inlet is ranged from 0.4 to 3 mm 2 ;

wherein the electronic cigarette further includes a seal ring, the seal ring is mounted at a side of the atomizer electrode away from the atomizer seat, and is configured to seal the battery container; the seal ring is provided with an opening, wherein the opening of the seal ring is communicated with the first through hole;

wherein the electronic cigarette further includes a threaded sleeve which is configured to make the atomizer electrode be fixed; the threaded sleeve is provided with an extension extending toward the atomizer electrode;

wherein the extension engages in an insulating ring, and is connected with the atomizer electrode; the threaded sleeve is connected with the atomizer electrode by the insulating ring to insulate heat and seal the electronic cigarette; and

wherein the first through hole, the second through hole and the channel are all coaxial; the battery container is integral with the outer sleeve.

3. The electronic cigarette of claim 1 , wherein a shape of the air inlet is any one of round, polygon, waist form and oval.
