Abstract

A vaporization device includes a vaporizer cartridge having a reservoir that holds a vaporizable material, a heating element, and a gel wicking element that can draw the vaporizable material to the heating element to be vaporized. The vaporizer cartridge is configured for coupling to a vaporizer device body and containing a vaporizable material. Various embodiments of the vaporizer cartridge are described that include one or more features for the wicking element. Various embodiments of the wicking element, as well as related systems, methods, and articles of manufacture are also described.

Claims (28)

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

a reservoir configured to contain a vaporizable material; and

an atomizer comprising a heating element and a gel wick, wherein the gel wick is in direct contact with the heating element and wherein the atomizer is configured to heat the vaporizable material to generate a vapor.

2. The cartridge of claim 1 , wherein the gel wick comprises a gel wick first end and a gel wick second end, wherein the gel wick first end and the gel wick second end are disposed within the reservoir.

3. The cartridge of claim 1 , wherein the gel wick is configured to draw the vaporizable material from the reservoir to the atomizer.

4. The cartridge of claim 1 , wherein the gel wick is formed and inserted into the heating element.

5. The cartridge of claim 1 , wherein the gel wick is formed around the heating element.

6. The cartridge of claim 1 , wherein the heating element is a wire or a mesh.

7. The cartridge of claim 6 , wherein the heating element comprises a nickel and chrome alloy.

8. The cartridge of claim 1 , wherein the gel wick comprises:

a superabsorbent polymer.

9. The cartridge of claim 8 , wherein the superabsorbent polymer is prepared from monomers selected from the group consisting of an acrylic acid, a salt of the acrylic acid, acrylamide, or combinations thereof.

10. The cartridge of claim 9 , wherein the superabsorbent polymer is a polyacrylamide.

11. The cartridge of claim 8 , wherein the superabsorbent polymer comprises a chemically-crosslinked polysaccharide or a graft polysaccharide-polyacrylonitrile.

12. The cartridge of claim 8 , wherein the superabsorbent polymer is formed in a presence of a crosslinker.

13. The cartridge of claim 1 , wherein the gel wick comprises:

an aqueous polysaccharide-based gellant system comprising:

a polysaccharide; and

a gel modifier.

14. The cartridge of claim 1 , wherein the gel wick comprises a cellulose matrix and a water-soluble polymer.

15. The cartridge of claim 1 , wherein the gel wick comprises an alginate and an alginate crosslinker.

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

a reservoir configured to contain a vaporizable material;

a heating element configured to heat the vaporizable material to generate a vapor; and

a wick consisting of a gel, wherein the wick is configured to transport the vaporizable material from the reservoir to the heating element.

17. The cartridge of claim 16 , wherein the gel is formed from a superabsorbent polymer, an aqueous polysaccharide-based gellant system, a cellulose matrix and a water-soluble polymer, or an alginate and an alginate crosslinker.

18. The cartridge of claim 17 , wherein the superabsorbent polymer is prepared from monomers selected from the group consisting of an acrylic acid, a salt of the acrylic acid, acrylamide, and combinations thereof.

19. The cartridge of claim 18 , wherein the superabsorbent polymer is a polyacrylamide.
