Abstract

A battery device for an electronic cigarette that comprises an atomizing device, the battery device comprising a housing with an accommodating inner cavity, a power supply assembly, a liquid storing assembly, and a connecting member, wherein the power supply assembly and the liquid storing assembly are both disposed within the accommodating inner cavity, the connecting member is disposed at an open end of the liquid storing assembly, allowing the atomizing device to be inserted into the liquid storing assembly through the open end and be detachably connected to the battery device through the connecting member. In the battery device of the present application, the liquid storing assembly is disposed therein, so that during an installation process, the user only needs to make one connection to complete the connection between the atomizing device, the battery device and the liquid storing assembly.

First claim

What is claimed is:

An electronic cigarette, comprising a battery device and an atomizing device, wherein the battery device comprises a liquid storing assembly, a housing with an accommodating inner cavity, and a power supply assembly disposed in the accommodating inner cavity, wherein the liquid storing assembly comprises a liquid storing base and a liquid storing tube, the liquid storing base comprises a fixed end and an open end opposite to the fixed end, the fixed end is disposed to be fixedly connected within the accommodating inner cavity, the open end extends out of the accommodating inner cavity, and a bottom end of the liquid storing tube is pluggably sleeved on the open end, an end of the atomizing device is allowed to be inserted from a top end of the liquid storing tube into the liquid storing tube and be detachably connected to the open end.

2. The electronic cigarette according to claim 1 , wherein the atomizing device comprises an upper cover, a connecting tube and an atomizing head, wherein the upper cover is detachably capped at the top end of the liquid storing tub, wherein one end of the connecting tube is detachably connected on the upper cover and another end of the connecting tube is detachably connected to the open end, and the atomizing head is sleeved within the connecting tube.

3. The electronic cigarette according to claim 2 , wherein the connecting tube is disposed, on one end connected to the open end, with external threads, and an inner circumferential surface of the top end of the open end extends inward to form a connecting portion whose inner diameter adapted to an outer diameter of the connecting tube, and an inner circumferential surface of the connecting portion is disposed with inner threads adapted to the external threads of the connecting tube.

4. The electronic cigarette according to claim 2 , further comprising a gas adjusting part which comprises a breather tube and a gas adjusting ring, wherein one end of the breather tube is inserted into the upper cap; the gas adjusting ring is rotatably sleeved on an outer circumference of another end of the breather pipe, and is disposed on a side wall with a gas-adjusting groove; and the upper cover is disposed with a gas inlet hole which is communicatively aligned or un-aligned with the gas-adjusting groove.

5. An electronic cigarette, comprising an atomizing assembly and a battery assembly, wherein the atomizing assembly comprises a gas inlet tube holder, a gas outlet tube, an atomizing head and an adjusting ring, wherein the gas inlet tube holder comprises a gas inlet tube and a gas inlet adjusting end connected to an end of the gas inlet tube; a channel of the gas inlet tube is in communication with a channel of the gas inlet adjusting end to form a passage of the gas inlet tube holder; the gas outlet tube is sleeved in the passage of the gas inlet tube holder, separating the passage of the gas inlet tube holder into a gas outlet passage and a gas inlet passage; the atomizing head is connected to the gas inlet tube at an end away from the gas inlet adjusting end; the adjusting ring is sleeved at the gas inlet adjusting end, the battery assembly comprises a battery housing disposed with a liquid storing cavity and a battery disposed in the battery housing, wherein the liquid storing cavity is used for containing cigarette liquid, and is disposed at a bottom with a battery polarity contact member which is electrically connected to the battery; the atomizing assembly is detachably mounted in the liquid storing cavity through the gas inlet tube holder, and the atomizing head is electrically connected to the battery polarity contact member.

6. The electronic cigarette according to claim 5 , wherein the gas inlet adjusting end comprises a gas inlet adjusting section whose tube wall is disposed with a gas inlet hole, wherein the adjusting ring is provided on an annular wall with a adjusting hole in communication with the gas inlet hole, wherein the amount of gas entering into the gas inlet passage can be adjusted by rotating or moving up and/or down the adjusting ring.

7. The electronic cigarette according to claim 5 , wherein the gas inlet tube holder comprises a connecting section disposed between the gas inlet tube and the gas inlet adjusting end, wherein the connecting section is formed on an outer circumferential wall with external threads; and the liquid storing cavity is disposed at a top end opening with internal threads adapted to the external threads.

8. The electronic cigarette according to claim 5 , wherein the battery housing comprises a main housing and an upper cover, wherein the main housing has a containing cavity in which the battery is assembled, and the containing cavity being capped by the upper cover.

9. The electronic cigarette according to claim 8 , wherein the main housing is disposed inside with a liquid storing tube, and comprises a base plate, side walls oppositely disposed on the base plate, and a connecting wall connecting a side of two side walls, wherein a top end of the connecting wall is lower than that of the side wall; an upper portion of the connecting wall is disposed with a top plate which is connected to the two side walls, and a liquid storing tube mounting space for mounting the liquid storing tube is formed at the top end of the connecting wall.

10. The electronic cigarette according to claim 9 , wherein the battery assembly further comprises a circuit board assembly, retaining bars are oppositely disposed on an inside of the two side walls, wherein the circuit board assembly comprises a circuit board and a battery dock, wherein the circuit board is on one face abutted against the retaining bars, and on another face fixedly connected to the battery dock, wherein the battery dock is disposed on one face opposite to the circuit board with a battery mounting space.

11. The electronic cigarette according to claim 5 , wherein the gas inlet tube holder is disposed on a top end with a stop ring whose outer circumference is disposed with a stop boss protruding therefrom, wherein the adjusting ring is disposed on an inner circumferential wall with a stop groove adapted to the stop boss; and the atomizing assembly comprises a rubber pad which is elastically abutted against and held between the stop boss and the stop groove.

12. The electronic cigarette according to claim 5 , wherein the atomizing head comprises an atomizing head sleeve, a positive pole contacting member, a positive pole insulating pad, a liquid absorbing member and a heating member, wherein the positive pole contacting member is sleeved at one end of the atomizing head sleeve, and is insulatively isolated from the atomizing head sleeve by the positive pole insulating pad; the liquid absorbing member is disposed within the atomizing head sleeve; the heating member is mounted within the atomizing head sleeve; and the heating member is connected on one end to the atomizing head sleeve, and on another end to the positive pole contact member.
