Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include first and second storage chambers each configured to hold a respective fraction of a vaporizable material, a vaporization chamber that includes an elongate member that is in fluid communication with the first and second storage chambers and configured to receive the vaporizable material, a magnetic element disposed within a channel of the elongate member, and a conductive element that is configured to generate a first motive force to drive the magnetic element between first and second positions and further configured to substantially vaporize the vaporizable material within the elongate member. Vaporizer devices are also provided.

Claims (30)

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

a first storage chamber and a second storage chamber, the first storage chamber being configured to hold a first fraction of a vaporizable material and the second storage chamber being configured to hold a second fraction of the vaporizable material;

an elongate member that is in fluid communication with the first storage chamber and the second storage chamber, the elongate member having a channel extending therethrough, the elongate member being configured to receive the vaporizable material; and

a magnetic element disposed within the channel of the elongate member, the magnetic element being configured to selectively oscillate between a first position and a second position so as to substantially control the flow of the vaporizable material into the elongate member.

2. The cartridge of claim 1 , further comprising a conductive element in selective communication with the magnetic element, the conductive element configured to substantially vaporize the vaporizable material within the elongate member to a vaporized material in response to receiving at least one electric current.

3. The cartridge of claim 2 , wherein the conductive element is configured to produce an alternating magnetic field.

4. The cartridge of claim 2 , wherein the at least one electric current includes a first electric current having a first polarity and a second electric current having a second polarity.

5. The cartridge of claim 2 , wherein the conductive element is a coil that is substantially wound about at least a portion of the elongate member.

6. The cartridge of claim 1 , wherein a portion of the first fraction of the vaporizable material flows into the elongate member when the magnetic element is in the second position.

7. The cartridge of claim 1 , further comprising an inlet valve positioned at a first end of the elongate member, the inlet valve configured to substantially prevent backflow of the portion of the first fraction of the vaporizable material from the elongate member and into the first storage chamber.

8. The cartridge of claim 1 , wherein a portion of the second fraction of the vaporizable material flows into the elongate member when the magnetic element is in the first position.

9. The cartridge of claim 1 , further comprising an inlet valve positioned at a second end of the elongate member, the inlet valve configured to substantially prevent backflow of the portion of the second fraction of the vaporizable material from the elongate member and into the second storage chamber.

10. The cartridge of claim 1 , wherein the magnetic element is a permanent magnet.

11. The cartridge of claim 1 , further comprising a vaporization chamber that 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 such that the vaporized material passes out of the vaporization 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 first storage chamber and a second storage chamber, the first storage chamber being configured to hold a first fraction of a vaporizable material and the second storage chamber being configured to hold a second fraction of the vaporizable material,

an elongate member that is in fluid communication with the first storage chamber and the second storage chamber, the elongate member having a channel extending therethrough, the elongate member being configured to receive the vaporizable material, and

a magnetic element disposed within the channel of the elongate member, the magnetic element being configured to selectively oscillate between a first position and a second position so as to substantially control the flow of the vaporizable material into the elongate member.

13. The device of claim 12 , wherein the cartridge includes a conductive element in selective communication with the magnetic element, the conductive element configured to substantially vaporize the vaporizable material within the elongate member to a vaporized material in response to receiving at least one electric current.

14. The device of claim 13 , wherein the conductive element is configured to produce an alternating magnetic field.

15. The device of claim 13 , wherein the at least one electric current includes a first electric current having a first polarity and a second electric current having a second polarity that is opposite the first polarity.

16. The device of claim 12 , wherein a portion of the first fraction of the vaporizable material flows into the elongate member when the magnetic element is in the second position.

17. The device of claim 16 , wherein the cartridge includes an inlet valve positioned at a first end of the elongate member, the inlet valve configured to substantially prevent backflow of the portion of the first fraction of the vaporizable material from the elongate member and into the first storage chamber.

18. The device of claim 12 , wherein a portion of the second fraction of the vaporizable material flows into the elongate member when the magnetic element is in the first position.

19. The device of claim 18 , wherein the cartridge includes an inlet valve positioned at a second end of the elongate member, the inlet valve configured to substantially prevent backflow of the portion of the second fraction of the vaporizable material from the elongate member and into the second storage chamber.

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

a first storage chamber and a second storage chamber, the first storage chamber being configured to hold a first fraction of a vaporizable material and the second storage chamber being configured to hold a second fraction of the vaporizable material; and

a magnetic element disposed within an elongate member in fluid communication with the first and second storage members, the magnetic element configured to selectively oscillate between a first position and a second position so as to substantially control the flow of the vaporizable material into the elongate member.
