Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing having a storage chamber and a dispensing chamber, and a vaporization chamber in communication with the dispensing chamber. The storage chamber is configured to hold a first fraction of a vaporizable material and the dispensing chamber is configured to hold a second fraction of the vaporizable material. The dispensing chamber is further configured to selectively dispense at least a first portion of the second fraction of the vaporizable material through at least one dispense opening in response to generation of one or more pressure pulses created within the dispensing chamber. The vaporizable chamber is configured to receive the dispensed vaporizable material from the dispensing chamber for vaporization by a first heating element to form a vaporized material. Vaporizer devices are also provided.

First claim

What is claimed is:

1. A cartridge for a vaporizer device, the cartridge comprising:
a reservoir housing having a storage chamber configured to hold a first fraction of a vaporizable material and a dispensing chamber configured to hold a second fraction of the vaporizable material, the dispensing chamber being further configured to selectively dispense at least a portion of the second fraction of the vaporizable material through at least one dispense opening in response to generation of one or more pressure pulses created within the dispensing chamber; and
a vaporization chamber in fluid communication with the dispensing chamber, the vaporization chamber being configured to receive the dispensed vaporizable material from the dispensing chamber for vaporization by a first heating element to form a vaporized material,
wherein the dispensing chamber includes a second heating element that is configured to selectively vaporize at least a second portion of the second fraction of the vaporizable material in response to activation of the second heating element, and wherein the vaporization of the second portion of the second fraction of the vaporizable material creates the one or more pressure pulses.

2. The cartridge of claim 1 , wherein the at least one dispense opening is configured to prevent passage of the vaporizable material therethrough when an internal pressure of the reservoir housing is substantially equal to ambient pressure outside of the reservoir housing.

3. The cartridge of claim 1 , wherein the storage chamber and the dispensing chamber are in fluid communication with each other, and wherein a portion of the first fraction of the vaporizable material is drawn into the dispensing chamber in response to the dispensed vaporizable material being expelled from the dispensing chamber.

4. The cartridge of claim 1 , wherein the storage chamber and the dispensing chamber are separated by a reservoir barrier having at least one orifice extending therethrough, and wherein the at least one orifice is configured to allow a portion of the first fraction of the vaporizable material to be drawn into the dispensing chamber in response to the dispensed vaporizable material being expelled from the dispensing chamber.

5. The cartridge of claim 1 , wherein the first heating element is configured to selectively flash evaporate the dispensed vaporizable material into vaporized material in response to activation of the first heating element.

6. The cartridge of claim 1 , wherein the vaporization chamber defines an airflow passageway that extends therethrough, and wherein the airflow passageway is configured to allow the vaporized material to combine with an influx of air to substantially form an aerosol.

7. A cartridge for a vaporizer device, the cartridge comprising:
a reservoir housing having a storage chamber configured to hold a first fraction of a vaporizable material and a dispensing chamber configured to hold a second fraction of the vaporizable material;
at least one heating element disposed within the dispensing chamber, the at least one heating element being configured to selectively vaporize at least a portion of the second fraction of the vaporizable material into vaporized material; and
a vaporization chamber in communication with the dispensing chamber, the vaporization chamber being configured to receive the vaporized material from the dispensing chamber and configured to allow the vaporized material to be withdrawn therefrom, wherein the vaporization chamber includes at least another heating element disposed therein.

8. The cartridge of claim 7 , wherein the vaporized material is dispensed from the dispensing chamber and into the vaporization chamber through at least one dispense opening that extends between the dispensing chamber and the vaporization chamber.

9. The cartridge of claim 8 , wherein the at least one dispense opening is configured to prevent passage of the vaporizable material therethrough when an internal pressure of the reservoir housing is substantially equal to ambient pressure outside of the reservoir housing.

10. The cartridge of claim 7 , wherein the storage chamber and the dispensing chamber are in fluid communication with each other, and wherein a portion of the first fraction of the vaporizable material is drawn into the dispensing chamber in response to the vaporized material being dispensed from the dispensing chamber.

11. The cartridge of claim 7 , wherein the storage chamber and the dispensing chamber are separated by a reservoir barrier having at least one orifice extending therethrough, and wherein the at least orifice is configured to allow a portion of the first fraction of the vaporizable material to be drawn into the dispensing chamber in response to the vaporized material being dispensed from the dispensing chamber.

12. 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 having a storage chamber configured to hold a first fraction of a vaporizable material and a dispensing chamber configured to hold a second fraction of the vaporizable material, the dispensing chamber being further configured to selectively dispense at least a portion of the second fraction of the vaporizable material through at least one dispense opening in response to generation of one or more pressure pulses created within the dispensing chamber, and
a vaporization chamber in fluid communication with the dispensing chamber, the vaporization chamber being configured to receive the dispensed vaporizable material from the dispensing chamber for vaporization by a first heating element to form a vaporized material,
wherein the dispensing chamber includes a second heating element that is configured to selectively vaporize at least a second portion of the second fraction of the vaporizable material in response to activation of the second heating element, and wherein the vaporization of the second portion of the second fraction of the vaporizable material creates the one or more pressure pulses.

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

14. The device of claim 12 , wherein the at least one dispense opening is configured to prevent passage of the vaporizable material therethrough when an internal pressure of the reservoir housing is substantially equal to ambient pressure outside of the reservoir housing.

15. The device of claim 12 , wherein the storage chamber and the dispensing chamber are in fluid communication with each other, and wherein a portion of the first fraction of the vaporizable material is drawn into the dispensing chamber in response to the dispensed vaporizable material being expelled from the dispensing chamber.

16. The device of claim 12 , wherein the storage chamber and the dispensing chamber are separated by a reservoir barrier having at least one orifice extending therethrough, and wherein the at least one orifice is configured to allow a portion of the first fraction of the vaporizable material to be drawn into the dispensing chamber in response to the dispensed vaporizable material being expelled from the dispensing chamber.

17. The device of claim 12 , wherein the first heating element is configured to selectively flash evaporate the dispensed vaporizable material into vaporized material in response to activation of the first heating element.

18. The device of claim 12 , wherein the vaporization chamber defines an airflow passageway that extends therethrough, and wherein the
