Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing, an airflow tube that extends through the reservoir housing, and a folded mesh that is disposed within the airflow tube and includes a plurality of folds. The airflow tube defines a passageway extending therethrough and at least a portion of the airflow tube is permeable to the vaporizable material, in which the permeable portion of the airflow tube is configured to draw vaporizable material from the reservoir housing into the airflow tube for vaporization. The folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize at least a portion of the vaporizable material drawn from the reservoir housing. Vaporizer devices are also provided.

Claims (32)

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

a reservoir housing being configured to hold a vaporizable material;

an airflow tube extending through the reservoir housing, the airflow tube defining a passageway extending therethrough, at least a portion of the airflow tube being permeable to the vaporizable material, the permeable portion of the airflow tube being configured to draw the vaporizable material from the reservoir housing into the airflow tube for vaporization; and

a folded mesh that is disposed within the airflow tube and includes a plurality of folds, the folded mesh having a capillary path and an electrical path such that the folded mesh is configured to draw vaporizable material directly from the reservoir housing and vaporize at least a portion of the drawn vaporizable material into vaporized material;

wherein the folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize the at least a portion of the drawn vaporizable material into vaporized material; and

wherein the capillary path extends along a width of the folded mesh, the width extending between adjacent folds of the plurality of folds, and wherein the electrical path extends a length of the folded mesh, the length extending from a first end to an opposing second end of the folded mesh.

2. The cartridge of claim 1 , wherein the permeable portion of the airflow tube includes a plurality of holes.

3. The cartridge of claim 1 , wherein the length of the folded mesh is less than a predetermined length of the folded mesh in an unfolded state.

4. The cartridge of claim 3 , wherein the airflow tube has a tube length that extends from a first end to a second end, and wherein the tube length is greater than the length of the folded mesh.

5. The cartridge of claim 1 , wherein the width of the folded mesh is greater than a radius of the airflow tube.

6. The cartridge of claim 1 , wherein a pressure equilibrium is created across the permeable portion of the airflow tube between the reservoir housing and the passageway when the folded mesh is in the deactivated state.

7. The cartridge of claim 1 , wherein a pressure differential is created across the permeable portion of the airflow tube between the reservoir housing and the passageway when the folded mesh is in the activated state.

8. The cartridge of claim 7 , wherein the vaporizable material flows from the reservoir housing into the airflow tube through the permeable portion of the airflow tube when the pressure differential is created.

9. The cartridge of claim 7 , wherein the pressure differential is created in response to the vaporization of at least a portion of the vaporizable material when the folded mesh is in the activated state.

10. The cartridge of claim 1 , wherein a portion of the vaporizable material is within the airflow tube when the folded mesh is in the deactivated state.

11. A vaporizer device, comprising:

a vaporizer body; and

a cartridge that is selectively coupled to and removable from the vaporizer body, the cartridge including:

a reservoir housing being configured to hold a vaporizable material,

an airflow tube extending through the reservoir housing, the airflow tube defining a passageway extending therethrough, at least a portion of the airflow tube being permeable to the vaporizable material, the permeable portion of the airflow tube being configured to draw the vaporizable material from the reservoir housing into the airflow tube for vaporization, and

a folded mesh that is disposed within the airflow tube and includes a plurality of folds, the folded mesh having a capillary path and an electrical path such that the folded mesh is configured to draw vaporizable material directly from the reservoir housing and vaporize at least a portion of the drawn vaporizable material into vaporized material;

wherein the folded mesh is configured to change from a deactivated state to an activated state in response to receiving an electric current, and when in the activated state, the folded mesh is configured to generate an amount of heat that is sufficient to vaporize the at least a portion of the drawn vaporizable material into vaporized material; and

wherein the capillary path extends along a width of the folded mesh, the width extending between adjacent folds of the plurality of folds, and wherein the electrical path extends a length of the folded mesh, the length extending from a first end to an opposing second end of the folded mesh.

12. The device of claim 11 , wherein the vaporizer body includes a power source.

13. The device of claim 11 , wherein the permeable portion of the airflow tube includes a plurality of holes.

14. The device of claim 11 , wherein the length of the folded mesh is less than a predetermined length of the folded mesh in an unfolded state.

15. The device of claim 11 , wherein the width of the folded mesh is greater than a radius of the airflow tube.

16. The device of claim 11 , wherein a pressure equilibrium is created across the permeable portion of the airflow tube between the reservoir housing and the passageway when the folded mesh is in the deactivated state.

17. The device of claim 11 , wherein a pressure differential is created across the permeable portion of the airflow tube between the reservoir housing and the passageway when the folded mesh is in the activated state.

18. The device of claim 17 , wherein the vaporizable material flows from the reservoir housing into the airflow tube through permeable portion of the airflow tube when the pressure differential is created.

19. The device of claim 17 , wherein the pressure differential is created in response to the vaporization of at least a portion of the vaporizable material when the folded mesh is in the activated state.

20. The device of claim 11 , wherein a portion of the vaporizable material is within the airflow tube when the folded mesh is in the deactivated state.
