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.

First claim

What is claimed is:

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; the battery rod and the e-liquid cup are disposed to be detachably connected.

9. According to the electronic cigarette in claim 8 , wherein corresponding ends of the inner cup body and the battery rod correspondingly disposes a first electrode assembly and a second electrode assembly which are used to electrically connect with the atomizer and the battery and make the e-liquid cup and the battery rod being securely abutted; the first electrode assembly includes a first seat body and a first electrode pole which are mutually insulated and respectively connects with two ends of the heating wire to form a positive electrode and a negative electrode of the atomizer; the second electrode assembly includes a second seat body and a second electrode pole which are mutually insulated and correspondingly connects to a positive electrode and a negative electrode of the battery respectively.

10. According to the electronic cigarette in claim 7 , wherein the atomizer is fixed between the mouthpiece and the battery by a supporting piece; the supporting piece is hollow tube structure, and an interior of the supporting piece forms an atomization chamber for conducting an air path and accommodating the atomizer; the atomizer further includes a liquid-guiding rod with two ends thereof stretching into the e-liquid cup to absorb e-liquid; the heating wire winds on the liquid-guiding rod; a sidewall of the supporting piece correspondingly disposes a latching opening radially through the sidewall for the liquid-guiding rod passing through.

11. According to the electronic cigarette in claim 1 , wherein a part or all of the outer cup body is disposed as transparent or semitransparent.

12. An electronic cigarette, comprising:
an atomization device;
an e-liquid cup disposed in the atomization device, the e-liquid cup comprising an inner cup body and an outer cup body, and an end cover, a first end of the inner cup body and a first end of the outer cup body being hermetically connected by the end cover so as to enclose with the outer cup body to form an e-liquid storage space, one end of the e-liquid storage space being sealed by the end cover, and the other end of the outer cup body being open to form an open end of the e-liquid cup; and
a mouthpiece being detachably connected with the open end of the e-liquid cup;
the other end of the outer cup body away from the end cover disposes a fixed groove, the fixed groove disposes a liquid-filling port communicating with the e-liquid storage space of the e-liquid cup, a corresponding end of the mouthpiece disposes a fixed boss matching with the fixed groove to insert into the fixed groove;
the other end of the outer cup body and the mouthpiece are mutually inserting connected;
the electronic cigarette further comprises a battery electrically connected with the atomization device and accommodated and fixed in the inner cup body, an external side of the battery is sheathed with a battery rod; the battery rod and the e-liquid cup are disposed to be detachably connected.

13. According to the electronic cigarette in claim 12 , wherein corresponding ends of the inner cup body and the battery rod correspondingly disposes a first electrode assembly and a second electrode assembly which are used to electrically connect with an atomizer of the atomization device and the battery and make the e-liquid cup and the battery rod being securely abutted; the first electrode assembly includes a first seat body and a first electrode pole which are mutually insulated and respectively connects with two ends of a heating wire of the atomization device to form a positive electrode and a negative electrode of the atomizer; the second electrode assembly includes a second seat body and a second electrode pole which are mutually insulated and correspondingly connects to a positive electrode and a negative electrode of the battery respectively.
