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.

Claims (12)

1. An electronic cigarette, comprising:

a battery assembly having a battery and an operating indicator;

an atomizer assembly in a housing;

the atomizer assembly including a ceramic porous component set on a front end of a frame inside of the housing, the ceramic porous component having a cavity, the cavity having an open first end and an obstructed second end;

liquid stored in the housing contacting the ceramic porous component;

the atomizer assembly having a heating element on the ceramic porous component, the heating element electrically connected to the battery assembly, the heating element oriented perpendicular to a longitudinal axis of the housing; and

an air flow path in the atomizer assembly in part parallel to the longitudinal axis of the housing;

wherein the frame has a run-through hole and the air flow path extends through the run-through hole to an outlet.

2. The electronic cigarette of claim 1 wherein the heating element comprises a heating layer made of a conductive material.

3. The electronic cigarette of claim 1 further including an airflow sensor electrically connected to an electronic circuit board in the housing.

4. The electronic cigarette of claim 1 wherein the ceramic porous component is configured to absorb the liquid and to move the liquid towards the heating element via capillary action.

5. The electronic cigarette of claim 1 wherein the frame has a first section having a first diameter, and a second section having a second diameter less than the first diameter, the second section coaxial with the first section, the second section engaging and aligning the ceramic porous component onto the frame.
