Abstract

An electronic cigarette includes a battery assembly, an atomizer assembly and a cigarette bottle assembly. An external thread electrode is located in one end of battery assembly. An internal thread electrode is located in one end of atomizer assembly. The battery assembly and the atomizer assembly are connected by the screwthread electrode. The cigarette bottle assembly is inserted into the other end of the atomizer assembly and both form a cigarette type or cigar type body.

Claims

1. An atomizer assembly for an electronic cigarette, comprising:

an atomizer assembly housing containing an atomizer, liquid storage, and a screw thread electrode on one end of the atomizer assembly housing, with the screw thread electrode having a through hole centered on the screw thread electrode, and

with the atomizer in physical contact with the liquid storage; and

a flow passageway leading from the atomizer to an outlet of the atomizer assembly housing.

2. The atomizer assembly for an electronic cigarette of claim 1 with the atomizer electrically connected to the screw thread electrode.

3. The atomizer assembly of claim 2 with the atomizer comprising a heater coil.

4. The atomizer assembly for an electronic cigarette of claim 1 with the atomizer including a heater coil wound around a porous component.

5. The atomizer assembly for an electronic cigarette of claim 4 where the porous component includes a fiber material.

6. The atomizer assembly for an electronic cigarette claim 1 with the screw thread electrode on a first end of the atomizer assembly housing and the liquid storage inserted into a second end of the atomizer assembly opposite from the first end.

7. The atomizer assembly for an electronic cigarette of claim 1 with the through hole substantially aligned with the atomizer.

8. The atomizer assembly for an electronic cigarette of claim 7 with the through hole in the screw thread electrode, the passageway and the outlet comprising a flow path through the atomizer assembly housing passing through the atomizer.

9. The atomizer assembly of claim 1 with part of the flow passageway between the liquid storage and an inside wall of the housing.

10. The atomizer assembly of claim 1 with the through-hole aligned with the atomizer.

11. An atomizer assembly for an electronic cigarette, comprising:

an atomizer assembly housing containing an atomizer and liquid storage;

a screw thread electrode on one end of the atomizer assembly housing;

a through-hole in the screw thread electrode substantially aligned with the atomizer;

the atomizer electrically connected to the screw thread electrode and with the atomizer in physical contact with the liquid storage; and

a flow passageway leading from the atomizer to an outlet of the atomizer assembly housing.

12. The atomizer assembly for an electronic cigarette of claim 11 with the atomizer including a heater coil wound around a porous component.
