Abstract

Vaporizer devices and apparatuses are provided. In some implementations, a cartridge comprises a storage compartment holding a vaporizable material, a wick in contact with the vaporizable material, a heating element in contact with the wick, a first plate positioned proximate to a first side of the cartridge and coupled to the heating element, and a second plate positioned proximate to a second side of the cartridge and coupled to the heating element, the first side opposite the second side. The heating element is configured to heat the vaporizable material to generate an aerosol comprising particles having diameters of an average size of about one micron or less. The first plate and the second plate define a volume therebetween, and at least a portion of the heating element is positioned within the volume.

First claim

What is claimed is:

1. A cartridge comprising:
a storage compartment holding a vaporizable material including a humectant, the humectant comprising a glycol;
a wick in contact with the vaporizable material;
a heating element in contact with the wick, the heating element configured to heat the vaporizable material to generate an aerosol comprising particles having diameters of an average size of about one micron or less;
a first plate positioned proximate to a first side of the cartridge, the first plate coupled to the heating element; and
a second plate positioned proximate to a second side of the cartridge, the second plate coupled to the heating element, the first side opposite the second side, the first plate and the second plate defining a volume therebetween, and at least a portion of the heating element positioned within the volume.

2. The cartridge of claim 1 , wherein the glycol comprises vegetable glycerol or propylene glycol.

3. The cartridge of claim 1 , wherein the glycol comprises vegetable glycerol, wherein the humectant further comprises propylene glycol, and wherein a ratio of the vegetable glycerol to the propylene glycol is within a range of about 80:20 vegetable glycerol to propylene glycol to about 50:50 vegetable glycerol to propylene glycol.

4. The cartridge of claim 1 , wherein the glycol comprises vegetable glycerol, wherein the humectant further comprises propylene glycol, and wherein a ratio of the vegetable glycerol to the propylene glycol is about 70:30 vegetable glycerol to propylene glycol.

5. The cartridge of claim 1 , wherein the cartridge has a proximal end and a distal end opposite the proximal end, and wherein the cartridge further comprises:
a mouthpiece at the proximal end, the first plate and the second plate positioned proximate to the distal end.

6. The cartridge of claim 5 , wherein the mouthpiece comprises a condensation chamber, and wherein the mouthpiece further comprises an aerosol outlet in fluid communication with the condensation chamber.

7. The cartridge of claim 5 , wherein the mouthpiece forms a cavity, wherein a first portion of the storage compartment is disposed inside of the cavity and a second portion of the storage compartment is disposed outside of the cavity.

8. The cartridge of claim 7 , wherein the second portion comprises a surface through which the vaporizable material is visible.

9. The cartridge of claim 1 , wherein the first plate and the second plate are configured to complete an electrical circuit with the heating element to provide power to the heating element.

10. The cartridge of claim 9 , further comprising:
a first flexible tab having a first contact surface disposed at a third side of the cartridge, the first flexible tab coupled to the first plate, the third side of the cartridge substantially perpendicular to the first side of the cartridge and substantially perpendicular to the second side of the cartridge; and
a second flexible tab having a second contact surface disposed at the third side of the cartridge, the second flexible tab coupled to the second plate.

11. The cartridge of claim 10 , wherein the first contact surface and the second contact surface are configured to couple with a pair of contacts in a vaporizer device to complete the electrical circuit, the electrical circuit comprising a battery within the vaporizer device and the heating element.

12. The cartridge of claim 1 , further comprising:
a heater chamber, wherein the first plate and the second plate are disposed at opposite sides of the heater chamber.

13. The cartridge of claim 12 , further comprising:
a plastic enclosure disposed to cover the first plate and the second plate, the first plate forming at least a portion of a first wall of the heater chamber, the second plate forming at least a portion of a second wall of the heater chamber, the first wall opposite the second wall.

14. The cartridge of claim 12 , wherein the heater chamber comprises the volume.

15. The cartridge of claim 1 , wherein the first plate comprises a first shape formed from an electrically conductive material, and wherein the second plate comprises a second shape formed from an electrically conductive material, the first shape substantially the same as the second shape.

16. The cartridge of claim 1 , further comprising:
a first shape formed from an electrically conductive material, the first shape comprising the first plate and a first flexible tab; and
a second shape formed from an electrically conductive material, the second shape comprising the second plate and a second flexible tab, the first shape substantially the same as the second shape.

17. The cartridge of claim 1 , wherein each of the first plate and the second plate comprise a heat sink configured to absorb and dissipate heat produced by the heating element.

18. An apparatus comprising:
a cartridge comprising:
a storage compartment holding a vaporizable material including a humectant, the humectant comprising a glycol;
a wick in contact with the vaporizable material;
a heating element in contact with the wick, the heating element configured to heat the vaporizable material to generate an aerosol comprising particles having diameters of an average size of about one micron or less;
a first plate positioned proximate to a first side of the cartridge, the first plate coupled to the heating element; and
a second plate positioned proximate to a second side of the cartridge, the second plate coupled to the heating element, the first side opposite the second side, the first plate and the second plate defining a volume therebetween, and at least a portion of the heating element positioned within the volume; and

a vaporizer device comprising:
a receptacle configured to insertably receive the cartridge;
a first contact configured to electrically couple with the first plate; and
a second contact configured to electrically couple with the second plate.

19. The apparatus of claim 18 , wherein the glycol comprises vegetable glycerol, wherein the humectant further comprises propylene glycol, and wherein a ratio of the vegetable glycerol to the propylene glycol is about 70:30 vegetable glycerol to propylene glycol.

20. The apparatus of claim 18 , wherein the cartridge has a proximal end and a distal end opposite the proximal end, and wherein the cartridge further comprises:
a mouthpiece at the proximal end, the first plate and the second plate positioned proximate to the distal end.

21. The apparatus of claim 20 , wherein the mouthpiece forms a cavity, wherein a first portion of the storage compartment is disposed inside of the cavity and a second portion of the storage compartment is disposed outside of the cavity.

22. The apparatus of claim 18 , wherein the first plate and the second plate are configured to complete an electrical circuit with the heating element to provide power to the heating element, the cartridge further comprising:
a first flexible tab having a first contact surface disposed at a third side of the cartridge, the first flexible tab coupled to the first plate, the third side of the cartridge substantially perpendicular to the first side of the cartridge and substantially perpendicular to the second side of the cartridge; and
