Abstract

A cartridge for use with a vaporization device comprising a first heating element, a first compartment for containment of a first vaporizable material, and a second compartment for containment of a second vaporizable material, wherein the device generates an aerosol for inhalation by a subject by heating the first vaporizable material or the second vaporizable material.

Claims

1. A device for generating an inhalable aerosol comprising:

a) a cartridge comprising;

i. a first vaporizable material;

ii. a first compartment that contains the first vaporizable material;

iii. a first heating element;

iv. a second vaporizable material; and

v. and a second compartment that contains the second vaporizable material; and

b) a body;

wherein the first vaporizable material in the first compartment is the same as or different than the second vaporizable material in the second compartment, and wherein the cartridge and body are coupled by a first connection mechanism that allows for detachment of the cartridge from the body, and wherein the first heating element is configured to vaporize the first vaporizable material.

2. The device of claim 1, comprising a second heating element, wherein the second heating element is configured to vaporize the second vaporizable material.

6. The device of claim 2, wherein the first heating element is configured to heat to a first target temperature, and the second heating element is configured to heat to a second target temperature, and wherein the first target temperature is the same as or different from the second target temperature.

10. The device of claim 1, comprising a first wicking material, wherein the first heating element comprises a first wire having a first end and a second end, the first wire in contact with the first wicking material, and wherein the first wicking material is in fluid communication with the first vaporizable material.

12. The device of claim 2, comprising:

a first wicking material, wherein the first heating element comprises a first wire having a first end and a second end, the first wire in contact with the first wicking material, wherein the first wicking material is in fluid communication with the first vaporizable material; and

a second wicking material, wherein the second heating element comprises a second wire having a third end and a fourth end, the second wire in contact with the second wicking material, wherein the second wicking material is in fluid communication with the second vaporizable material.

14. The device of claim 12, wherein the first wicking material and the second wicking material have the same material properties or different material properties.

15. The device of claim 12, wherein the first wicking material and the second wicking material have the same wicking properties or different wicking properties.

16. The device of claim 12, wherein the first wicking material and the second wicking material have the same wicking rate or different wicking rate.

19. The device of claim 1, wherein the first compartment and the second compartment are in series or in parallel within the cartridge relative to an airflow path.

21. The device of claim 1, wherein the first compartment and the second compartment share a common axis within the cartridge.

22. The device of claim 21, wherein the common axis is aligned with a central axis of an airflow path.

23. The device of claim 1, wherein the first compartment and the second compartment are stacked, concentric, aligned around a central axis, or in a parallel alignment within the cartridge.

25. The device of claim 1, wherein the first compartment and the second compartment are replaceable with a third compartment or a fourth compartment in the cartridge.

28. The device of claim 1, wherein the first compartment comprises a first airflow path, and the second compartment comprises a second airflow path that is in communication with the first airflow path.

29. The device of claim 2, wherein the first compartment comprises a first airflow path, and the second compartment comprises a second airflow path, wherein a first vapor or condensate thereof from the first airflow path is introduced to a second vapor or condensate thereof from the second airflow path prior to exiting the cartridge.

30. The device of claim 29, wherein the first compartment comprises a first chamber comprising the first airflow path, and the second compartment comprises a second chamber comprising the second airflow path, wherein introduction of the first vapor or condensate thereof to the second vapor or condensate thereof occurs in the second chamber.

31. The device of claim 29, wherein the cartridge comprises a third chamber and introduction of the first vapor or condensate thereof to the second vapor or condensate thereof occurs in the third chamber.

73. The device of claim 1, further comprising a first capacitive sensing zone and a second capacitive sensing zone, the first zone electrically isolated from the second zone, wherein the first zone comprises a first capacitive sensor and the second zone comprises a second capacitive sensor, and wherein when the first zone and second zone are configured so that when a user swipes a finger from the first zone to the second zone or from the second zone to the first zone, the device communicates information to the user, the information comprising, a battery charge level, a vaporizable material level, a pre-heat state, or a combination thereof.

74. The device of claim 1, further comprising a first capacitive sensing zone and a second capacitive sensing zone, the first zone electrically isolated from the second zone, wherein the first zone comprises a first capacitive sensor and the second zone comprises a second capacitive sensor, and wherein when the first zone and second zone are configured so that when a user swipes a finger from the first zone to the second zone or from the second zone to the first zone, the device is activated.
