Abstract

A vaporizer device includes a housing, a wick element that is configured to contact a vaporizable substance, an induction heating element located within the housing and inductively coupled to the wick element and not in contact with the wick element, and a power source electrically connected to the induction heating element. The wick element is positioned such that the induction heating element is around the wick element and the wick element is surrounded by the induction heating element. The wick element is configured to heat the vaporizable substance based on induction heating. The induction heating element receives an alternating current from the power source and creates an electromagnetic induction field around the wick element, and the wick element generates heat based on the electromagnetic induction field.

Claims (24)

1. A vaporizer device comprising:

a housing;

a wick element comprising a container that is configured to contact a vaporizable substance, the wick element comprising a susceptor material;

an induction heating element located within the housing and inductively coupled to the wick element and not in contact with the wick element, wherein the wick element is positioned such that the induction heating element is around the wick element, and wherein the wick element is surrounded by the induction heating element, wherein the induction heating element comprises an induction coil; and

a power source electrically connected to the induction heating element;

wherein the wick element is configured to heat the vaporizable substance based on induction heating of the wick element by the induction heating element;

wherein the vaporizable substance is transferred along the wick element based on a capillary action of the vaporizable substance along the wick element; and

wherein the induction heating element receives an alternating current from the power source and creates an electromagnetic induction field around the wick element, and wherein the wick element generates heat based on the electromagnetic induction field.

2. The vaporizer device of claim 1 , wherein the container of the wick element comprises a metal container, wherein the metal container is a solid metal cylinder.

3. The vaporizer device of claim 1 , further comprising an insulating member disposed between the wick element and the induction heating element.

4. The vaporizer device of claim 3 , wherein the induction coil is disposed about the insulating member.

5. The vaporizer device of claim 4 , wherein the insulating member defines an inside surface and wherein the wick element is positioned adjacent to the inside surface of the insulating member.

6. The vaporizer device of claim 1 , wherein the wick element comprises a magnetic material or a metallic conductor.

7. The vaporizer device of claim 6 , wherein the wick element has a material configuration, wherein the material configuration is selected from the group consisting of a mesh, a plurality of strands, a porous solid material, and any combination thereof.

8. The vaporizer device of claim 1 , wherein the induction heating element is configured to heat the wick element to a predetermined temperature to cause the vaporizable substance to produce a vapor for inhalation.

9. The vaporizer device of claim 8 , wherein the vaporizable substance is selected from the group consisting of a liquid, a wax, a plant material, and any combination thereof.

10. The vaporizer device of claim 1 , further comprising at least one additional heating element.

11. The vaporizer device of claim 10 , wherein the at least one additional heating element is a resistive heating element or another induction heating element.

12. The vaporizer device of claim 1 , further comprising a processor coupled to the induction heating element, wherein the processor is configured to control operation of the induction heating element.

13. The vaporizer device of claim 12 , wherein the processor is programmed to restrict operation of the induction heating element to a specific user of the vaporizer device.

14. The vaporizer device of claim 13 , wherein the processor is programmed to cause the induction heating element to apply a predetermined heating profile to the vaporizable substance.

15. The vaporizer device of claim 14 , wherein the predetermined heating profile is based on the vaporizable substance.

16. The vaporizer device of claim 1 , wherein the wick element is formed from two or more materials.

17. The vaporizer device of claim 1 , wherein the wick element is configured to be removeable and replaceable within the induction coil of the induction heating element.
