Abstract
Aspects of the instant disclosure relate to electronic cigarettes; more particularly, to electronic cigarettes including a power supply portion. In various embodiments, the eCig power supply portion includes a sub-assembly housing substantially containing a battery, an airflow sensor, and controller circuitry. Aspects of the disclosure are further directed to an eCig power supply portion further including a hemicylindrical port and/or electrical contacts aligned along a longitudinal axis of the power supply portion.
Claims16
An electronic cigarette power supply portion comprising:
- a sub-assembly housing including
- a second keying feature along an exterior surface, wherein the second keying feature is disposed on the exterior surface and protrudes from the exterior surface, along an entire length of the exterior surface;
- and
- an exterior tube with a first keying feature along an interior surface of the tube, wherein the first keying feature is defined within the interior surface, the first keying feature configured and arranged to mate to the second keying feature of the sub-assembly housing, and axially align the sub-assembly housing within the exterior tube;
- a battery;
- an airflow sensor electrically connected to the battery;
- controller circuitry electrically connected to the battery and configured and arranged to operate the electronic cigarette;
- and
- wherein the sub-assembly housing and at least one of the controller circuitry and the airflow sensor form an aperture, the airflow sensor further configured and arranged to detect a flow of air through the aperture.
