Abstract

The invention is related to an electronic cigarette, including an atomizing device with a tobacco-liquid cup, and a battery electrically connected with the atomizing device, herein, the tobacco-liquid cup forms a recessed cavity, the battery is received in the cavity. The battery of the present invention is set in the atomizing device, so that the whole length of the electronic cigarette is effectively reduced, and it is more convenient to take the electronic cigarette.

Claims

1. An electronic cigarette, comprising an atomizing device with a tobacco-liquid cup, and a battery electrically connected with the atomizing device;

wherein the tobacco-liquid cup defines a recessed cavity, and the battery is arranged in the recessed cavity.

2. The electronic cigarette of claim 1, wherein the tobacco-liquid cup comprises an outer cup body and an inner cup body, a first end of the inner cup body and the outer cup body are tightly connected whereby the inner cup body and the outer cup body enclose a liquid-storing space, and the inner cup body is hollow to form the recessed cavity for receiving the battery.

3. The electronic cigarette of claim 2, wherein the tobacco-liquid cup is set with a mouthpiece near a second end of the inner cup body;

the mouthpiece through its center defines an inhaling port to communicate with an air passageway for vapor mist being drawn therethrough;

the atomizing device further comprises an atomizer disposed between the mouthpiece and the battery to vaporize tobacco liquid into vapor mist.

4. The electronic cigarette of claim 3, wherein the atomizer comprises an electric heat wire;

the second end of the inner cup body is set with a first electrode assembly which is electrically connected with the electric heat wire and the battery;

the first electrode assembly comprises a first seat and a first terminal post both of which are insulated from each other and respectively electrically connected with both ends of the electric heat wire to form positive and negative electrodes of the atomizer.

5. The electronic cigarette of claim 4, wherein the battery rod is fitted outside of the battery;

one end of the battery rod abutting against the first electrode assembly is set with a second electrode assembly coupled to the first electrode assembly;

the second electrode assembly comprises a second seat and a second terminal post both of which are insulated from each other and respectively connected with positive and negative poles of the battery.

6. The electronic cigarette of claim 5, wherein the battery rod and the tobacco-liquid cup are detachably connected.

7. The electronic cigarette of claim 6, wherein the tobacco-liquid cup is set with a first magnetic part where the tobacco-liquid cup is interconnected with the battery rod;

the battery rod is correspondingly set with a second magnetic part drawing the first magnetic part whereby the tobacco-liquid cup and the battery rod are tightly interconnected.

8. The electronic cigarette of claim 7, wherein the first seat is made from conductive magnet or magnetic materials to form the first magnetic part, or the first electrode assembly is set with a separate component made from magnet or magnetic materials to form the first magnetic part;

the second seat is made from conductive magnet or magnetic materials to form the second magnetic part, or the second electrode assembly is set with a separate component made from magnet or magnetic materials to form the second magnetic part.

9. The electronic cigarette of claim 7, wherein the first end of the inner cup body is tightly connected with the outer cup body by a end cap;

the end cap is made from magnet or magnetic materials to form the first magnetic part, or the end cap is set with a separate component made from magnet or magnetic materials to form the first magnetic part;

the battery rod is set with a battery cover away from the atomizer for enclosing the battery;

the battery cover is made from magnet or magnetic materials to form the second magnetic part, or the battery cover is set with a separate component made from magnet or magnetic materials to form the second magnetic part.

10. The electronic cigarette of claim 5, wherein the second seat is hollow and tubular, its end facing the battery defines an accommodating cavity for receiving the second terminal post;

the second terminal post is fixed in the accommodating cavity by means of an insulation sleeve.

11. The electronic cigarette of claim 10, wherein the insulation sleeve comprises a first insulation support and a second insulation support both of which are interconnected and define an inner chamber;

the second terminal post is elastically fitted in center of the insulation sleeve by means of a compression spring fixed in the inner chamber;

both the first insulation support and the second insulation support axially define a first terminal hole and a second terminal hole in their opposite end walls to communicate with the inner chamber for both ends of the second terminal post extending therethrough;

the second terminal post forms a blocking ring in the inner chamber;

the compression spring has both ends thereof respectively abutting against the blocking ring and an inner wall of the second insulation support, whereby one end of the second terminal post facing the first electrode assembly remains extending outwards.

12. The electronic cigarette of claim 4, wherein the atomizer is arranged between the mouthpiece and the first seat via a support;

the support is hollow and tubular, its center forms an atomizing chamber to communicate with the air passageway and receive the atomizer.

13. The electronic cigarette of claim 12, wherein the atomizer further comprises a liquid-delivery rod with both ends thereof extending into the tobacco-liquid cup to absorb tobacco liquid;

the electric heat wire winds round the liquid-delivery rod;

the support defines openings radially through its side wall for fitting the liquid-delivery rod.

14. The electronic cigarette of claim 12, wherein one end of the first seat extends into the support to form a brace tightly fitted with the first seat;

a sealing bush is set where the mouthpiece and the support are connected.

15. The electronic cigarette of claim 2, wherein the outer cup body is partly or wholly transparent or semitransparent.
