Electronic cigarette

1. An electronic cigarette, comprising a hollow and tubular cigarette pipe, the cigarette pipe comprising a cigarette rod and a mouthpiece, wherein the cigarette rod and/or the mouthpiece have paper film attached on its surface;

the cigarette pipe is set with a tobacco-liquid cup therein, and the tobacco-liquid cup comprises a cup body which is concentrically and tensionally fitted on an inner wall of the cigarette pipe and an atomizing seat which is hermetically fixed to one end of the cup body;

an atomizing device is fixed in the cup body along its radial direction, and the atomizing device comprises a liquid-guiding piece and an electric heat wire round the liquid-guiding piece;

the cup body comprises a hollow tubular liquid-storing cotton, a liquid-guiding cotton, a first glass-fiber tube and a second glass-fiber tube; the liquid-storing cotton is fitted on the inner wall of the cigarette pipe and is concentric with the cigarette pipe; the liquid-guiding cotton is fitted on an inner wall of the liquid-storing cotton, concentric to the cigarette pipe and with engagement of the atomizing device; a middle section of the liquid-guiding cotton peripherally defines a groove; the first glass-fiber tube forms a spiral by a glass fiber being spirally wound, and is received in the groove; the second glass-fiber tube is fitted on an inner wall of the first glass-fiber tube and the liquid-guiding cotton, and is concentric with the cigarette pipe; and

the liquid-guiding piece of the atomizing device crosses holes of the second glass-fiber tube and then abutting on the inner wall of the first glass-fiber tube; whereby tobacco liquid is absorbed fast and much concentrated for the electric heat wire and the atomizing device is gripped and fixed tight.

2. The electronic cigarette of claim 1 , wherein the cigarette pipe has plastic film attached on its section without paper film.

3. The electronic cigarette of claim 1 , wherein there is a plastic film further attached on an outer surface of the paper film.

4. The electronic cigarette of claim 1 , wherein the paper film is made from one or more materials chosen from writing paper, heat sensitive paper, or copperplate paper.

5. The electronic cigarette of claim 2 , wherein the plastic film uses one or more kinds of chosen from PET film, PP film or PVC film.

6. The electronic cigarette of claim 1 , wherein the mouthpiece of the electronic cigarette is set with a mouthpiece cover at its corresponding end and the mouthpiece cover defines an inhaling hole.

7. The electronic cigarette of claim 6 , wherein the mouthpiece cover is made from one or more materials chosen from silica gel, rubber, foam, or EVA materials.

8. The electronic cigarette of claim 1 , wherein the cigarette rod of the electronic cigarette at its corresponding end is set with a transparent cigarette cap, the cigarette cap has a spherical shape convex outward, and a light source is set inside the cigarette cap.

9. The electronic cigarette of claim 1 , wherein the cigarette pipe is made from one or more materials chosen from silica gel, rubber, foam, or EVA materials.

10. The electronic cigarette of claim 1 , wherein a battery is set in the cigarette pipe at its end corresponding to the cigarette rod; two electrodes of the battery are connected with both ends of the electric heat wire by wires respectively passing through the atomizing seat and cup body.

11. The electronic cigarette of claim 10 , wherein a fixing bracket is set in the cigarette pipe at its end corresponding to the cigarette rod, and an air sensor is mounted in the fixed bracket with an electric connection to the battery.

12. The electronic cigarette of claim 3 , wherein the plastic film uses one or more kinds of chosen from PET film, PP film or PVC film.

13. An electronic cigarette, comprising a hollow and tubular cigarette pipe, the cigarette pipe comprising a cigarette rod and a mouthpiece, wherein the cigarette pipe is set with a tobacco-liquid cup and an atomizing device therein; the tobacco-liquid cup is set in the cigarette pipe, comprising a cup body and an atomizing seat fixed to one end of the cup body, the cup body is concentrically fitted in the cigarette pipe; the cup body comprises a hollow and tubular liquid-storing cotton, a liquid-guiding cotton, a first glass-fiber tube and a second glass-fiber tube; the liquid-storing cotton is concentric fitted on an inner wall of the cigarette pipe; the liquid-guiding cotton is concentric fitted on an inner wall of the liquid-storing cotton and is engaged with the atomizing device; the liquid-guiding cotton peripherally defines a groove; the first glass-fiber tube forms a spiral by a glass fiber being spirally wound, and is received in the groove; the second glass-fiber tube is fitted on an inner wall of the first glass-fiber tube and the liquid-guiding cotton, and is concentric to the cigarette pipe; the atomizing device is fixed in the cup body along its radial direction, and comprises a liquid-guiding piece which crosses corresponding holes of the second glass-fiber tube and then abutting on the inner wall of the first glass-fiber tube, and an electric heat wire round the liquid-guiding piece; whereby tobacco liquid is absorbed fast and much concentrated for the electric heat wire and the atomizing device is gripped and fixed tight.
