Abstract

An electronic cigarette includes a battery assembly and an atomizer assembly within a housing with the battery assembly electrically connected to the atomizer assembly. The housing has one or more air inlets. A liquid storage component is in contact with a porous component of the atomizer assembly, with the porous component having a run-through hole. A heating wire is in an air flow path through the run-through hole.

First claim

The invention claimed is:

1. An electronic cigarette, comprising:
a battery assembly having a cylindrical battery and an operating indicator;
an atomizer assembly in an elongated cylindrical housing, with the battery assembly electrically connected to the atomizer assembly, and with the cylindrical battery coaxial with the atomizer assembly;
a liquid storage component in the housing;
the atomizer assembly including a porous component set on a frame having a run-through hole;
a heating wire coil electrically connected to the battery;
an air flow path in the atomizer assembly parallel to a longitudinal axis of the housing, with the air flow path through the run-through hole to an outlet, with the heating wire coil wound on the porous component and in the air flow path and with the heating wire coil oriented perpendicular to the longitudinal axis; and
the porous component in contact with the liquid storage component.

2. The electronic cigarette of claim 1 with the porous component having a first section perpendicular to the longitudinal axis and having a second section parallel to the longitudinal axis.

3. The electronic cigarette of claim 1 with the frame having a cylindrical first section and a second section, with the second section between the first section and the outlet, and with the second section longer than the first section.

4. The electronic cigarette of claim 3 wherein the first section of the frame is a cylindrical base section.

5. The electronic cigarette of claim 1 with the battery assembly further including an air flow sensor.

6. The electronic cigarette of claim 5 with the battery assembly further comprising an electronic circuit board electrically connected to the air flow sensor.

7. The electronic cigarette of claim 1 wherein the porous component is cylindrical.

8. An electronic cigarette, comprising:
a battery assembly having a cylindrical battery and an operating indicator;
an atomizer assembly in an elongated cylindrical housing having a longitudinal axis, with the battery assembly electrically connected to the atomizer assembly, and with the cylindrical battery coaxial with the atomizer assembly;
the atomizer assembly including a porous component having a first section perpendicular to the longitudinal axis and a second section parallel to the longitudinal axis, with the porous component set on a frame having a run-through hole;
a heating wire coil wound on the first section of the porous component and electrically connected to the battery;
an air flow path in the atomizer assembly parallel to the longitudinal axis, with the air flow path through the run-through hole to an outlet, and the heating wire coil in the air flow path and oriented perpendicular to the longitudinal axis; and
a liquid storage component in the housing in contact with the porous component.

9. The electronic cigarette of claim 8 with the second section of the porous component on opposite sides of the first section of the porous component.

10. The electronic cigarette of claim 8 with the frame having a cylindrical first section and a second section, with the second section between the first section and the outlet, and with the second section longer than the first section.

11. An electronic cigarette, comprising:
an atomizer assembly and a liquid storage component in an elongated cylindrical housing having a longitudinal axis;
battery assembly electrically connected to the atomizer assembly, and with the battery assembly including a cylindrical battery coaxial with the atomizer assembly;
the atomizer assembly including:
a frame comprising a cylindrical base having a run-through hole;
a fiber member in contact with the liquid storage component;
a heating wire coil wound on the fiber member and oriented perpendicular to the longitudinal axis, and the heating wire coil electrically connected to the battery, with the fiber member moving liquid from the liquid storage component to the heating wire coil by capillary action; and
an air flow path parallel to the longitudinal axis through the atomizer assembly, with the air flow path passing through the run-through hole, and with the heating wire coil in the air flow path and perpendicular to the longitudinal axis.

12. The electronic cigarette of claim 11 with a first part of the fiber member perpendicular to the longitudinal axis and the heating wire coil wrapped on the first part.

13. The electronic cigarette of claim 11 with the fiber member having a first section perpendicular to the longitudinal axis and having a second section parallel to the longitudinal axis.

14. The electronic cigarette of claim 11 with the frame having a cylindrical first section and a second section, with the second section between the first section and the outlet, and with the second section longer than the first section.
