Abstract

The present invention relates to an electronic cigarette, including an atomization device disposed with an e-liquid cup, and a mouthpiece disposed at one end of the e-liquid cup. The e-liquid cup has an e-liquid storage space. One end of the e-liquid storage space is sealed and the other end of the e-liquid storage space is open. The mouthpiece is detachably connected with an open end of the e-liquid cup. The mouthpiece of the electronic cigarette of the present invention is detachably connected with the open end of the e-liquid cup, the electronic cigarette has few components, and simple structure, and is convenient to add e-liquid.

Claims

1. An electronic cigarette, comprising an atomization device disposed with an e-liquid cup, and a mouthpiece disposed at one open end of the e-liquid cup;

the other end of the e-liquid cup being sealed as one sealed end, wherein the mouthpiece is detachably connected with the open end of the e-liquid cup;

the electronic cigarette further comprises a battery which is electrically connected with the atomization device;

the sealed end of the e-liquid cup away from the mouthpiece has a cavity body which is concave, the battery is accommodated and fixed in the cavity body;

the e-liquid cup comprises an outer cup body and an inner cup body;

both the outer cup body and the inner cup body are hollow tube structure;

the inner cup body is disposed in the outer cup body, a first end of the inner cup body is hermetically connected with the outer cup body so as to form the sealed end of the e-liquid cup, a second end of the inner cup body is not connected with the outer cup body so as to form the opening end of the e-liquid cup for adding e-liquid;

the outer cup body and the inner cup body cooperatively enclose to form an annular space therebetween as an e-liquid storage space; and

an interior of the inner cup body with the hollow tube structure forms the cavity body to accommodate the battery therein.

2. According to the electronic cigarette in claim 1, wherein the open end of the e-liquid cup disposes a fixed groove abutting with a corresponding end of the mouthpiece;

the fixed groove disposes a liquid-filling port communicating with the e liquid storage space of the e-liquid cup.

3. According to the electronic cigarette in claim 2, wherein the corresponding end of the mouthpiece disposes a fixed boss matching with the fixed groove to insert into the fixed groove.

4. According to the electronic cigarette in claim 3, wherein the fixed boss of the mouthpiece is sheathed with a sealing ring which is tensioningly fixed between the fixed boss and the fixed groove.

5. According to the electronic cigarette in claim 3, wherein the e-liquid cup and the mouthpiece are mutually inserting connected;

and the corresponding end of the mouthpiece abutting with the e-liquid cup disposes a sealing ring, and tensioningly fixed with the fixed groove by the sealing ring.

6. According to the electronic cigarette in claim 5, wherein the corresponding end of the mouthpiece abutting with the e-liquid cup correspondingly disposes a clamping slot for clamping the sealing ring;

or the clamping slot is disposed on a corresponding sidewall of the fixed groove.

7. According to the electronic cigarette in claim 1, wherein the atomization device further comprises an atomizer disposed with a heating wire;

the heating wire is electrically connected with the battery to vaporize e-liquid to aerosol when power on.

8. According to the electronic cigarette in claim 7, wherein an external side of the battery is sheathed with a battery rod;
