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 (31)

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

an atomizer that 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; 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 substantially form an aerosol downstream of the atomizer,

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, and

wherein the first airflow path segment and the second airflow path segment intersect at a second junction that is upstream of the first junction, wherein the second junction 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.

2. The cartridge of claim 1 , wherein the second junction is a T-junction.

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

4. The cartridge of claim 1 , 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.

5. 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.

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

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

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

an airflow channel that defines an airflow path that extends through the cartridge, the airflow path being configured to receive and substantially allow air to flow into and through the airflow channel; and

an atomizer that includes a wicking element that is configured to substantially draw a vaporizable material from a reservoir and into the atomizer, a heating element that is configured to substantially vaporize the vaporizable material into a vaporized material, and a vapor chamber that is in communication with the wicking element and the airflow channel;

wherein the vapor chamber is configured to substantially allow at least a portion of the vaporized material to pass therethrough and into the airflow channel so that the portion of the vaporized material mixes with the air to form an aerosol outside of the atomizer, and

wherein the wicking element extends from a first surface to an opposing second surface, and wherein the first surface and second surface each extend substantially parallel to the airflow path.

9. The cartridge of claim 8 , wherein at least a portion of the vapor chamber is bounded by the airflow channel, and wherein the portion of the vapor chamber is formed of a permeable material that is configured to allow the vaporized material to substantially pass therethrough and into the airflow path.

10. The cartridge of claim 8 , wherein the heating element directs heat across a lateral surface of the wicking element extending between the first and second surfaces.

11. The cartridge of claim 10 , wherein the lateral surface is interposed between a bulk of the wicking element and the vapor chamber.

12. The cartridge of claim 8 , wherein the vapor chamber includes at least one vent that extends between the vapor chamber and the airflow channel, and wherein the at least one vent is configured to substantially direct the vaporized material from the vapor chamber and into the airflow path.

13. The cartridge of claim 12 , wherein a velocity of the air flowing adjacent to the at least one vent substantially creates a pressure differential across the at least one vent and between the vapor chamber and the airflow channel.

14. 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 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, 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 substantially form an aerosol downstream of the atomizer,

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, and

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 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.

15. The device of claim 14 , wherein the vaporizer body includes a power source.
