Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include an atomizer and a channel extending through the cartridge from an inlet to an outlet. The atomizer includes a wicking element that is configured to substantially draw a vaporizable material from a reservoir and into the atomizer, and a heating element that is configured to substantially vaporize the vaporizable material into a vaporized material. The channel has an airflow path and a vapor path that intersect at a first junction between the inlet and the outlet. The airflow path is configured to receive and substantially allow air to pass therethrough, and the vapor path is configured to direct the vaporized material into the first junction so that the vaporized material mixes with the air to substantially form an aerosol downstream of the atomizer. Vaporizer devices are also provided.

Claims (32)

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

an atomizer that includes a heating element that is configured to substantially vaporize a vaporizable material into a vaporized material; and

a channel extending through the cartridge from an inlet to an outlet, the channel having an airflow path and a vapor path that intersect at a first junction between the inlet and the outlet and that are each an uninterrupted path, the airflow path being configured to receive and allow air to pass therethrough;

wherein the atomizer is in communication with the vapor path such that the vaporized material flows into the vapor path, and wherein the vapor path is configured to direct the vaporized material into the first junction so that the vaporized material mixes with the air to substantially form an aerosol downstream of the atomizer.

2. The cartridge of claim 1 , wherein the airflow path includes a first airflow path segment and a second airflow path segment, and wherein the first airflow path segment is in communication with the atomizer.

3. The cartridge of claim 2 , wherein the first airflow path segment and the second airflow path segment intersect at a second junction that is upstream of the first junction.

4. The cartridge of claim 3 , wherein the second junction is a T-junction.

5. The cartridge of claim 3 , wherein the second junction substantially diverts a first portion of the air into the first airflow path segment and across the atomizer, and wherein the second junction further diverts a second portion of the air towards the first junction.

6. The cartridge of claim 5 , wherein the first portion of air has a first volume and the second portion of air has a second volume that is greater than the first volume.

7. The cartridge of claim 1 , wherein a portion of the air is configured to substantially transport the vaporized material from the atomizer and into the first junction.

8. The cartridge of claim 1 , wherein a portion of the airflow path that is downstream of the first junction is configured to substantially allow the aerosol to pass therethrough and out of the channel.

9. The cartridge of claim 1 , wherein the aerosol is substantially formed at the first junction.

10. The cartridge of claim 1 , wherein the first junction is a T-junction.

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

an atomizer that includes a heating element that is configured to substantially vaporize a vaporizable material into a vaporized material; and

a channel extending through the cartridge from an inlet to an outlet, the channel having an airflow path and a vapor path that intersect at a first junction between the inlet and the outlet, the airflow path being configured to receive and substantially allow air to pass therethrough;

wherein the atomizer is in communication with the vapor path such that the vaporized material flows into the vapor path, and wherein the vapor path is configured to direct the vaporized material into the first junction so that the vaporized material mixes with the air to allow for primary condensation of the vaporized material to occur outside of the atomizer;

wherein the airflow path includes a first airflow path segment and a second airflow path segment, wherein a first portion of the air is diverted into the first airflow path segment and across the atomizer, the first portion having a first volume, and wherein a second portion of the air is diverted towards the first junction, the second portion of air having a second volume that is greater than the first volume.

12. The cartridge of claim 11 , wherein the first airflow path segment is in communication with the atomizer.

13. The cartridge of claim 11 , wherein the first airflow path segment and the second airflow path segment intersect at a second junction that is upstream of the first junction.

14. The cartridge of claim 13 , wherein at least one of the first junction or the second junction is a T-junction.

15. The cartridge of claim 11 , wherein a portion of the airflow path that is downstream of the first junction is configured to substantially allow the aerosol to pass therethrough and out of the channel.

16. The cartridge of claim 11 , wherein the aerosol is substantially formed at the first junction.

17. A vaporizer device, comprising:

a vaporizer body; and

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

an atomizer that includes a heating element that is configured to substantially vaporize a vaporizable material into a vaporized material, and

a channel extending through the cartridge from an inlet to an outlet, the channel having an airflow path and a vapor path that intersect at a first junction between the inlet and the outlet and that are each an uninterrupted path, the airflow path being configured to receive and substantially allow air to pass therethrough;

wherein the atomizer is in communication with the vapor path such that the vaporized material flows into the vapor path, and wherein the vapor path is configured to direct the vaporized material into the first junction so that the vaporized material mixes with the air to substantially form an aerosol downstream of the atomizer.

18. The device of claim 17 , wherein the vaporizer body includes a power source.

19. The device of claim 17 , wherein the airflow path includes a first airflow path segment and a second airflow path segment, and wherein the first airflow path segment is in communication with the atomizer.

20. The device of claim 19 , wherein the first air flow path segment and the second airflow path segment intersect at a second junction that is upstream of the first junction, wherein the second junction substantially diverts a first portion of the air into the first airflow path segment and across the atomizer, and wherein the second junction further diverts a second portion of the air towards the first junction.
