Abstract
A reservoir component of an electronic vaping device includes an outer housing, an air inlet, a vapor outlet, an air passage communicating with the air inlet and the vapor outlet, and a reservoir. A magnetic, electrically conductive and resistive heater element is located adjacent the air passage. The heater element is configured to be in electrical communication with an alternator of a power supply component. A wick is in communication with the reservoir and is configured to draw pre-vapor formulation from the reservoir toward the heater element. The heater element is configured to heat pre-vapor formulation to a temperature sufficient to vaporize the pre-vapor formulation and form a vapor.
Claims27
A reservoir component of an electronic vaping device comprising:
- an outer housing extending in a longitudinal direction;
- an air inlet;
- a vapor outlet in communication with the air inlet;
- an air passage between the air inlet and the vapor outlet;
- a reservoir in the outer housing;
- a heater element located adjacent the air passage, the heater being magnetic, electrically conductive, and resistive;
- and
- a wick in communication with the reservoir, the wick configured to draw pre-vapor formulation from the reservoir toward the heater element.
A power supply component of an electronic vaping device comprising:
- an outer housing extending in a longitudinal direction;
- a power source;
- a heater element positioned adjacent an end of the power supply component, the heater being magnetic, electrically conductive;
- an alternator in electrical communication with the power source, the alternator configured to produce an alternating current when powered by the power source, the alternator configured to drive the magnetic, electrically conductive and resistive heater element with the alternating current.
A method of producing a vapor from an electronic vaping device, comprising:
- drawing a portion of a pre-vapor formulation from a reservoir towards a heater element, the heater element being magnetic, electrically conductive, and resistive;
- and
- vaporizing at least some of the drawn portion of the pre-vapor formulation by driving the heater element with an alternating current by an alternator in electrical communication with a power source, such that current density through the heater element concentrates along an outer surface of the heater element to resistively heat the outer surface of the heater element.
An electronic vaping device, comprising:
- a pre-vapor formulation;
- a heater element in proximity of at least a portion of said pre-vapor formulation, the heater element being magnetic, electrically conductive, and resistive;
- a source of alternating current;
- and
- an arrangement configured to responsively communicate the heater element with the source, such that magnetism in the heater element and the alternating current of the source heat a surface portion of the heater element such that the pre-vapor formulation is at least partially vaporized.
