Electronic vaping device and components thereof

Abstract

A liquid reservoir component of an electronic vaping device includes an outer casing extending in a longitudinal direction, an air inlet, and a vapor outlet. An inner tube is within the outer casing defining a central air passage communicates with the inlet and the outlet. A liquid reservoir is in an annular space between the outer casing and the inner tube. A susceptor is adjacent the central air passage, and a wick is in communication with the liquid reservoir and in thermal communication with the susceptor such that the susceptor is operable to heat the liquid material to a temperature to vaporize the liquid material and form a vapor in the central air passage. The liquid reservoir component is configured to connect with a power supply component such that an induction source is operable to generate an inductive field to heat the susceptor when powered by the power source.
