Abstract

A vaporizer device includes a cartridge having a reservoir that holds a vaporizable material and an atomizer chamber that includes a heating element. The heating element can heat the vaporizable material. The heating element can include two rigid portions that are spaced apart by a span that defines a capillary gap. The capillary gap can draw the vaporizable material from the reservoir to a heater region to be vaporized.

Claims (34)

1. A cartridge for a vaporizer device, the cartridge comprising:

a reservoir configured to hold a vaporizable material;

a heating element configured to heat the vaporizable material, the heating element comprising:

a capillary structure including a plurality of rigid portions,

wherein pairs of the plurality of rigid portions are spaced apart from one another to define a capillary gap therebetween, the capillary gap configured to draw the vaporizable material from the reservoir to a heater region of the heating element to be heated, and an aerosol being generated by the heating of the vaporizable material drawn to the heater region of the heating element, the plurality of rigid portions comprising an upper rigid portion and a lower rigid portion, the lower rigid portion being integrally formed with the upper rigid portion and spaced apart from the upper rigid portion by a span that defines the capillary gap, the heating element forming a single portion that is folded to define the upper rigid portion and the lower rigid portion; and

wherein the upper rigid portion of the plurality of rigid portions comprises an upper vaporization portion having a plurality of upper gaps and the lower rigid portion of the plurality of rigid portions comprises a lower vaporization portion having a plurality of lower gaps, and wherein the plurality of upper gaps are positioned laterally offset from the plurality of lower gaps; and

an air inlet configured to direct a flow of air across the heater region such that when the heating element is activated, the vaporizable material drawn into the capillary gap at the heater region is vaporized into the flow of air through at least one of the plurality of upper gaps and the plurality of lower gaps.

2. The cartridge of claim 1 , wherein the plurality of rigid portions of the capillary structure further comprises:

an upper end portion configured to be in fluid communication with the reservoir; and

a lower end portion comprising a heater.

3. The cartridge of claim 1 , wherein the plurality of rigid portions of the capillary structure further comprises:

an inner rigid portion defining a channel; and

an outer rigid portion surrounding the inner rigid portion and spaced apart from the inner rigid portion by a span that defines the capillary gap.

4. The cartridge of claim 1 , wherein the heating element is at least partially positioned within the reservoir.

5. The cartridge of claim 1 , wherein the heating element comprises an electrically conductive layer.

6. The cartridge of claim 5 , wherein the electrically conductive layer comprises a trace pattern.

7. The cartridge of claim 1 , wherein the heating element comprises nichrome.

8. The cartridge of claim 1 , further comprising an atomizer chamber housing that surrounds at least a portion of the heating element, the atomizer chamber housing comprising a cutout region.

9. The cartridge of claim 8 , wherein the cutout region is configured to receive a porous material configured to absorb the vaporizable material.

10. The cartridge of claim 1 , wherein the upper rigid portion is positioned parallel to the lower rigid portion.

11. The cartridge of claim 1 , wherein the heating element comprises a plurality of perforations to allow the vaporizable material to evaporate therethrough.

12. A vaporizer device comprising:

a vaporizer device body; and

the cartridge of claim 1 .

13. A vaporizer device comprising:

a reservoir configured to hold a vaporizable material;

a heating element configured to heat the vaporizable material, the heating element comprising:

a capillary structure including a plurality of rigid portions,

wherein pairs of the plurality of rigid portions are spaced apart from one another to define a capillary gap therebetween, the capillary gap configured to draw the vaporizable material from the reservoir to a heater region of the heating element to be heated, and an aerosol being generated by the heating of the vaporizable material drawn to the heater region of the heating element, the plurality of rigid portions comprising an upper rigid portion and a lower rigid portion, the lower rigid portion being integrally formed with the upper rigid portion and spaced apart from the upper rigid portion by a span that defines the capillary gap, the heating element forming a single portion that is folded to define the upper rigid portion and the lower rigid portion; and

wherein the upper rigid portion of the plurality of rigid portions comprises an upper vaporization portion having a plurality of upper gaps and the lower rigid portion of the plurality of rigid portions comprises a lower vaporization portion having a plurality of lower gaps, and wherein the plurality of upper gaps are positioned laterally offset from the plurality of lower gaps; and

an air inlet configured to direct a flow of air across the heater region such that when the heating element is activated, the vaporizable material drawn into the capillary gap at the heater region is vaporized into the flow of air through at least one of the plurality of upper gaps and the plurality of lower gaps.

14. The vaporizer device of claim 13 , wherein the plurality of rigid portions of the capillary structure further comprises:

an upper end portion configured to be in fluid communication with the reservoir; and

a lower end portion comprising a heater.
