Abstract

An atomizing device of an electronic cigarette without a liquid reserving member is provided. The atomizing device includes an atomizing sleeve, a support, a heating assembly, and a ventilation member fixed inside the atomizing sleeve. The ventilation member includes an air pipe and a flange formed on the air pipe. The flange includes a cavity in communication with the air pipe, and the air pipe is fixed on the support. An annular space for containing a tobacco solution is formed between the air pipe and the atomizing sleeve. The heating assembly is placed under the support. An electronic cigarette having the atomizing device and the ventilation member is also disclosed.

Claims

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

an atomizing sleeve;

a support received in the atomizing sleeve;

a heating assembly; and

a ventilation member fixed inside the atomizing sleeve;

wherein the ventilation member comprises an air pipe and a flange formed on the air pipe, the flange comprises a cavity in communication with the air pipe, the air pipe is fixed on the support, then an annular space for containing a tobacco solution is formed between the air pipe and the atomizing sleeve, and the heating assembly is positioned under the support.

2. The atomizing device of claim 1, wherein the support is ring-shaped, and comprises an inner space in communication with the air pipe and configured as an atomizing chamber of the heating assembly.

3. The atomizing device of claim 1, wherein a sealing cover is arranged on the support.

4. The atomizing device of claim 1, wherein a slot is formed between an outer wall of the support and an inner wall of the atomizing sleeve to allow the tobacco solution flow towards the heating assembly.

5. The atomizing device of claim 1, wherein the ventilation member is T-shaped, and a junction surface between the flange and the air pipe is an inclined surface or a curved surface.

6. The atomizing device of claim 1, wherein a reinforcing rib is fixed at an outer wall of the air pipe and a length of the reinforcing rib is shorter than that of the air pipe.

7. The atomizing device of claim 1, wherein the flange and the air pipe are integrally formed.

8. The atomizing device of claim 1, wherein the flange and the air pipe are both made of plastic materials.

9. The atomizing device of claim 1, wherein a sealing ring is arranged on an outer wall of the flange.

10. The atomizing device of claim 1, wherein a guiding wall extends downwards from the flange along a direction parallel to the air pipe.

16. An electronic cigarette comprising a battery assembly and an atomizing device of claim 1, the battery assembly is configured to be electrically connected to the atomizing device.

11. A ventilation member of an atomizing device, comprising:

an air pipe and a flange formed on the air pipe, a cavity being formed in the flange and in communication with the air pipe.

12. The ventilation member of claim 11, wherein the ventilation member is T-shaped and a junction surface between the flange and the air pipe is an inclined surface or a curved surface.

13. The ventilation member of claim 11, wherein a reinforcing rib is arranged on an outer wall of the air pipe and a length of the reinforcing rib is shorter than that of the air pipe.

14. The ventilation member of claim 11, wherein the flange and the air pipe are integrally formed.

15. The ventilation member of claim 11, wherein a guiding wall is extended downwards from the flange along a direction parallel to the air pipe.
