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.

First claim

We claim:

1. An electronic vaping (e-vaping) device comprising:
a liquid reservoir configured to contain a liquid material;
a susceptor;
an induction source configured to generate an inductive field to heat the susceptor; and
a wick in communication with the liquid reservoir, the wick contacting the susceptor and configured to be 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, the wick and the susceptor being twined together.

2. The e-vaping device of claim 1 , wherein the induction source includes an inductive coil at an end thereof proximate to the susceptor, and the inductive coil is configured to generate the inductive field to heat the susceptor.

3. The e-vaping device of claim 2 , wherein the inductive coil comprises a helix.

4. The e-vaping device of claim 2 , wherein the inductive coil comprises a planar coil.

5. The e-vaping device of claim 2 , wherein the induction source further includes a cylindrical core comprising a ferrite material, the inductive coil is wound about the cylindrical core.

6. The e-vaping device of claim 1 , wherein the susceptor is at least one conductive filament.

7. The e-vaping device of claim 1 , wherein the susceptor comprises at least one of stainless steel, copper, copper alloys, ceramic material coated with film resistive material, nickel chromium alloys, a sub-combination thereof or a combination thereof.

8. The e-vaping device of claim 1 , wherein the susceptor is made of a magnetic material.

9. The e-vaping device of claim 1 , wherein the susceptor is an inductively heatable ribbon of mesh material.
