Leak-resistant vaporizer device
Vaporizer cartridges and vaporizer apparatuses, and methods for making, using and delivering vapor to a user, that are leak-resistant for use with cannabinoids. In particular, described herein are leak-resistant vaporizer cartridges and apparatuses adapted for use with oil-based vaporizable materials including cannabis oils.
1. A vaporizer device comprising:
a cartridge comprising:

a first electrical contact disposed at a second end of the cartridge opposite the first end;
a second electrical contact disposed at the second end;
a reservoir configured to contain the vaporizable material;
an atomizer configured to heat the vaporizable material;
a first cartridge air inlet disposed at the second end and adjacent to the first electrical contact; and
a second cartridge air inlet disposed at the second end and adjacent to the second electrical contact;
wherein the first cartridge air inlet and the second cartridge air inlet are configured to deliver air to the atomizer; and
a vaporizer body comprising:
a cartridge receiver configured to insertably receive the cartridge, the cartridge receiver comprising a base end;
a first base connector configured to engage with the first electrical contact, the first electrical contact disposed proximate to the base end when the cartridge is insertably received in the cartridge receiver;
a second base connector configured to engage with the second electrical contact, the first electrical contact disposed proximate to the base end when the cartridge is insertably received in the cartridge receiver;
a first body air inlet defining a first opening in a first side of the vaporizer body; and
a second body air inlet defining a second opening in a second side of the vaporizer body opposite the first side;
wherein the cartridge and the vaporizer body defines an air flow path comprising:
the first body air inlet and the second body air inlet;
a region between the second end of the cartridge and the base end of the cartridge receiver;
the first cartridge air inlet and the second cartridge air inlet; and
a cannula extending between the atomizer and the mouthpiece through the reservoir.
2. The vaporizer device of claim 1 , wherein the first body air inlet and the second body air inlet are aligned with the region between the second end of the cartridge and the base end of the cartridge receiver.
3. The vaporizer device of claim 1 , wherein the cartridge is configured to be secured at least partially within the vaporizer body via a friction fitting.
4. The vaporizer device of claim 3 , wherein the friction fitting is defined by a ridge on the cartridge and a complimentary region within the cartridge receiver of the vaporizer body.
5. The vaporizer device of claim 1 , wherein the cartridge further comprises:
an overflow leak chamber formed between the reservoir and the second end; and
one or more absorbent pads positioned within the overflow leak chamber, the one or more absorbent pads positioned off-axis relative to the air flow path through the overflow leak chamber.
6. The vaporizer device of claim 5 , wherein the air flow path further comprises the overflow leak chamber.
7. The vaporizer device of claim 1 , wherein the vaporizer body further comprises:
a pressure sensor configured to detect a draw on the mouthpiece to activate the vaporizer body; and
a channel extending from the base end of the cartridge receiver to the pressure sensor.
8. The vaporizer device of claim 1 , wherein the first electrical contact and the second electrical contact each comprises a comprise pin receptacles.
9. The vaporizer device of claim 1 , wherein the atomizer extends across the air flow path in a transverse direction.
10. A vaporizer device comprising:
a cartridge comprising:
a first electrical contact disposed at an insertion end of the cartridge;
a second electrical contact disposed at the insertion end;
a reservoir configured to contain a vaporizable material;
an atomizer configured to heat the vaporizable material contained within the reservoir;
a first cartridge air inlet disposed at the insertion end; and
a second cartridge air inlet disposed at the insertion end, wherein air is configured to be delivered to the atomizer through the first cartridge air inlet and the second cartridge air inlet; and
a vaporizer body comprising:
a cartridge receiver configured to insertably receive the cartridge, the cartridge receiver comprising a base end configured to face the insertion end of the cartridge,
a first body air inlet defining a first opening in a first side of the vaporizer body; and
a second body air inlet defining a second opening in a second side of the vaporizer body opposite the first side;
wherein the cartridge and the vaporizer body define an air flow path comprising:
the first body air inlet and the second body air inlet;
a region between the insertion end of the cartridge and the base end of the cartridge receiver;
the first cartridge air inlet and the second cartridge air inlet; and
a cannula extending from the atomizer to an outlet of the cartridge through the reservoir.
11. The vaporizer device of claim 10 , wherein the first body air inlet and the second body air inlet are aligned with the region between the insertion end of the cartridge and the base end of the cartridge receiver.
12. The vaporizer device of claim 10 , wherein the cartridge is configured to be secured at least partially within the vaporizer body via a friction fitting.
13. The vaporizer device of claim 12 , wherein the friction fitting is defined by a ridge on the cartridge and a complimentary region within the cartridge receiver of the vaporizer body.
14. The vaporizer device of claim 10 , wherein the cartridge further comprises:
an overflow leak chamber formed between the reservoir and the insertion end; and
one or more absorbent pads positioned within the overflow leak chamber, the one or more absorbent pads positioned off-axis relative to the air flow path through the overflow leak chamber.
15. The vaporizer device of claim 14 , wherein the air flow path further comprises the overflow leak chamber.
16. The vaporizer device of claim 10 , wherein the vaporizer body further comprises:
a pressure sensor configured to detect a draw on the cartridge to activate the vaporizer body; and
a channel extending from the base end of the cartridge receiver to the pressure sensor.
17. The vaporizer device of claim 10 , wherein the first electrical contact and the second electrical contact each comprises a comprise pin receptacles.
18. The vaporizer device of claim 10 , wherein the atomizer extends across the air flow path in a transverse direction.
