Electronic cigarette and atomizing assembly thereof

1. An atomizing assembly of an electronic cigarette, comprising:

a hollow stem;

a conduit positioned inside the stem and comprising a first segment and a second segment in communication with the first segment, wherein the first segment has a first transverse inner dimension inside the first segment and the second segment has a second transverse inner dimension inside the second segment; the first transverse inner dimension is larger than the second transverse inner dimension;

a storage chamber positioned between the hollow stem and the conduit for holding an atomizable material, wherein the storage chamber is partially confined by both an outer wall of the first segment and an outer wall of the second segment;

an atomizable material conveying device; and

an atomizer arranged inside the first segment of the conduit,

wherein, when in use, the atomizable material conveying device conveys the atomizable material to the atomizer, and the atomizer, when powered, atomizes the atomizable material into an aerosol.

2. The atomizing assembly of claim 1 , wherein the outer wall of the first segment has a first transverse outer dimension and the outer wall of the second segment has a second transverse outer dimension; and the first transverse outer dimension is larger than the second transverse outer dimension.

3. The atomizing assembly of claim 1 , defining a first end and a second end, opposite to the first end, wherein the first segment is adjacent to the first end, and an outlet of the second segment, away from the first segment, is adjacent to the second end.

4. The atomizing assembly of claim 3 , further comprising electric connectors positioned at the first end for connecting the atomizer to a powering unit.

5. The atomizing assembly of the claim 1 , wherein the atomizer comprises a heating device.

6. The atomizing assembly of the claim 1 , wherein the atomizable material conveying device comprises an absorbing device.

7. An atomizing assembly of an electronic cigarette, comprising:

a hollow stem;

a conduit positioned inside the hollow stem and comprising a first segment and a second segment in communication with the first segment, wherein the first segment has a first transverse inner dimension inside the first segment and the second segment has a second transverse inner dimension inside the second segment; and the first transverse inner dimension is larger than the second transverse inner dimension;

a mouthpiece adjacent to one end of the hollow stem and in communication with one end of the second segment of the conduit away from the first segment;

a storage chamber positioned inside the hollow stem and surrounding the conduit for holding an atomizable material, wherein an outer wall of the conduit partially confines the storage chamber, and the outer wall of the conduit comprises an outer wall of the first segment where the first segment has a first transverse outer dimension and an outer wall of a second segment where the second segment has a second transverse outer dimension; and the first transverse outer dimension is larger than the second transverse outer dimension;

a heating device arranged inside the first segment of the conduit; and

an absorbing device,

wherein, when in use, the absorbing device conveys the atomizable material to the heating device, and the heating device, when powered, atomizes the atomizable material into an aerosol.

8. The atomizing assembly of claim 7 , a first end of the atomizing assembly comprises electric connectors for connecting the atomizer to a powering unit, and the mouthpiece is positioned at a second end of the atomizing assembly, opposite to the first end.

9. An electronic cigarette, comprising:

an atomizing assembly, comprising:

a hollow stem;

a conduit positioned inside the stem and comprising a first segment and a second segment in communication with the first segment, wherein the first segment has a first transverse inner dimension inside the first segment and the second segment has a second transverse inner dimension inside the second segment; the first transverse inner dimension is larger than the second transverse inner dimension;

a storage chamber positioned between the hollow stem and the conduit for holding an atomizable material, wherein the storage chamber is partially confined by the outer wall of the conduit, and the outer wall of the conduit comprises an outer wall of the first segment where the first segment has a first transverse outer dimension and an outer wall of the second segment where the second segment has a second transverse outer dimension; and

the first transverse outer dimension is larger than the second transverse outer dimension;

an atomizable material conveying device; and

an atomizer arranged inside the first segment of the conduit; and

a powering unit,

wherein, when in use, the atomizable material conveying device conveys the atomizable material to the atomizer, and the atomizer is powered by the powering unit to atomize the atomizable material into an aerosol; and the aerosol travels from the first segment, through the second segment, to be consumed by a user.

10. The electronic cigarette of claim 9 , wherein the atomizing assembly further comprises a first end and a second end, opposite to the first end; and the first segment is adjacent to the first end, and an outlet of the second segment, away from the first segment, is adjacent to the second end.

11. The electronic cigarette of claim 9 , wherein the atomizing assembly further comprises electric connectors positioned at the first end, and the atomizer is connected to the powering unit via the electric connectors.

12. The electronic cigarette of the claim 9 , wherein the atomizable material conveying device comprises an absorbing device.

13. The electronic cigarette of the claim 9 , wherein the atomizer comprises a heating device.
