Abstract

Provided is a cartridge assembly for containment of a vaporizable substance to be used in an electronic vaporizer device. The cartridge assembly includes a cartridge and a susceptor element. The cartridge includes a base section and a side section coupled to the base section at a first end of the side section. An aperture is defined at a second end of the side section and the side section includes at least two apertures located in the side section, where the at least two apertures are configured to allow air to flow into an interior chamber of the cartridge when air flows out of the aperture defined at the second end. The susceptor element is located within the cartridge.

Claims (70)

1. An electronic vaporizer device, comprising:

a cartridge configured to hold a vaporizable substance, the cartridge comprising:

a base section,

a side section coupled to the base section at a first end of the side section, wherein an aperture is defined at a second end of the side section,

wherein the side section comprises one or more apertures located in the side section, the one or more apertures being configured to allow air to flow into an interior of the cartridge when air flows out of the aperture defined at the second end,

wherein the base section and the side section define a fluid reservoir;

a susceptor element located within the cartridge; and

an induction heating element inductively coupled to the susceptor element and not in contact with the susceptor element,

wherein the one or more apertures comprises a first aperture and a second aperture,

wherein the first aperture is adjacent the second end of the side section and the second aperture is adjacent the first aperture,

wherein the second aperture is vertically offset and horizontally offset from the first aperture, and

wherein the first aperture is smaller than the second aperture.

2. The electronic vaporizer device of claim 1 ,

wherein the one or more apertures are configured to allow a volume of air into an interior chamber of the cartridge, and

wherein the volume of air is based on a volume per unit length of the cartridge.

3. The electronic vaporizer device of claim 1 ,

wherein the susceptor element comprises a plurality of wire strands that are wound together in a helical formation, and

wherein the wire strands comprise a ferromagnetic material.

4. The electronic vaporizer device of claim 1 , wherein the cartridge has a cylindrical shape.

5. The electronic vaporizer device of claim 1 ,

wherein the one or more apertures comprises a plurality of slit apertures located in the side section, and

wherein a size of an opening of the plurality of slit apertures is greater at a location adjacent the base section of the cartridge than a size of the opening of the plurality of slit apertures adjacent the second end of the side section.

6. The electronic vaporizer device of claim 1 , wherein the susceptor element comprises a wire having a coating of at least one of zirconia, silicon dioxide, or alumina.

7. The electronic vaporizer device of claim 1 ,

wherein the susceptor element comprises a plurality of wire strands,

wherein each wire strand has a same diameter, and

wherein the susceptor element has a pitch in a range of 25 wire diameters to 1 wire diameter.

8. The electronic vaporizer device of claim 1 , wherein the cartridge is positioned such that the induction heating element surrounds at least a portion of the cartridge and surrounds at least a portion of the susceptor element.

9. The electronic vaporizer device of claim 8 , further comprising:

a power source electrically connected to the induction heating element,

wherein the susceptor element is configured to heat a vaporizable substance located in the fluid reservoir based on induction heating of the susceptor element by the induction heating element,

wherein the susceptor element is located in the fluid reservoir and is further configured to transfer the vaporizable substance from the fluid reservoir based on a capillary action of the susceptor element,

wherein the induction heating element receives an alternating current from the power source and creates an electromagnetic field around the susceptor element, and

wherein the susceptor element generates heat based on the electromagnetic field.

10. The electronic vaporizer device of clan 1 ,

further comprising a shielding element,

wherein the shielding element is located within the cartridge, and

wherein the susceptor element is located within the shielding element.

11. The electronic vaporizer device of claim 10 , wherein the shielding element surrounds a portion of the susceptor element when the susceptor element is located within the shielding element.

12. The electronic vaporizer device of claim 1 ,

wherein the one or more apertures comprises a third aperture,

wherein the third aperture is adjacent the second end of the side section and opposite the first aperture, and

wherein the third aperture is smaller than the second aperture.

13. The electronic vaporizer device of claim 12 ,

wherein the one or more apertures comprises a fourth aperture,

wherein the fourth aperture is adjacent the first aperture and the third aperture, and

wherein the fourth aperture is larger than the first aperture and the third aperture.

14. A cartridge assembly for containment of a vaporizable substance to be used in an electronic vaporizer device, the cartridge assembly comprising:

a cartridge comprising:

a base section,

a side section coupled to the base section at a first end of the side section, wherein an aperture is defined at a second end of the side section, and

wherein the side section comprises at least two apertures located in the side section, where the at least two apertures are configured to allow air to flow into an interior chamber of the cartridge when air flows out of the aperture defined at the second end, and

a susceptor element located within the cartridge,

wherein the at least two apertures comprise a first aperture and a second aperture,

wherein the first aperture is adjacent the second end of the side section and the second aperture is adjacent the first aperture,

wherein the second aperture is vertically offset and horizontally offset from the first aperture, and

wherein the first aperture is smaller thanthe second aperture.

15. The cartridge assembly of claim 14 ,

wherein the one or more apertures is configured to allow a volume of air into the interior chamber of the cartridge, and

wherein the volume of air is based on a volume per unit length of the cartridge.

16. The cartridge assembly of claim 14 ,

wherein the susceptor element comprises a plurality of wire strands that are wound together in a helical formation, and

wherein the wire is a ferromagnetic material.

17. The cartridge assembly of claim 14 . wherein the susceptor element comprises a wire having a coating of at least one of zirconia, silicon dioxide, or alumina.

18. The cartridge assembly of claim 14 ,

further comprising a shielding element,

wherein the shielding element is located within the cartridge,

wherein the susceptor element is located within the shielding element,

wherein the susceptor element comprises a first ferromagnetic material and the shielding element comprises a second ferromagnetic material, and

wherein the first ferromagnetic material has greater ferromagnetic properties than the second ferromagnetic material.
