Heating element
A heating element for a vaporizer cartridge is provided. The vaporizer cartridge may include a reservoir containing vaporizable material and a wicking element in fluid communication with the reservoir. The heating element may include a heating portion, a cartridge contact, and a leg. The heating portion includes at least two tines spaced apart from one another. The cartridge contact may be in electrical communication with a power source. The leg extends between the heating portion and the cartridge contact. The heating portion may be crimped around the wicking element such that the heating portion secures the wicking element to the heating element and contacts at least two surfaces of the wicking element.
1. A heating element of a vaporizer device comprising a reservoir containing vaporizable material and a wicking element in fluid communication with the reservoir, the heating element comprising:
a heating portion comprising at least two tines spaced apart from one another, the at least two tines comprising a first side tine portion, a second side tine portion opposing and approximately parallel to the first side tine portion, and a platform tine portion connecting the first side tine portion with the second side tine portion, the heating portion being preformed to define an interior volume configured to receive the wicking element such that the heating portion secures at least a portion of the wicking element to the heating element, the interior volume defined by the first side tine portion, the second side tine portion, and the platform tine portion, the heating portion being configured to contact at least two separate surfaces of the wicking element; and
at least two legs coupled to the at least two tines and spaced apart from the heating portion, the at least two legs configured to electrically communicate with a power source,
wherein power is configured to be supplied to the heating portion from the power source to generate heat, thereby vaporizing the vaporizable material stored within the wicking element.
2. The heating element of claim 1 , wherein the at least two legs includes four legs.
3. The heating element of claim 2 , wherein the heating portion is configured to contact at least three separate surfaces of the wicking element.
4. The heating element of claim 1 , wherein
the platform tine portion is positioned approximately perpendicular to a portion of the first side tine portion and the second side tine portion.
5. The heating element of claim 1 , wherein the at least two legs are located away from the heating portion by a bridge.
6. The heating element of claim 1 , wherein each of the at least two legs includes a cartridge contact positioned at an end of each of the at least two legs, the cartridge contact configured to electrically communicate with the power source, the cartridge contact being angled and extending away from the heating portion.
7. The heating element of claim 1 , wherein the at least two tines includes a first pair of tines and a second pair of tines.
8. The heating element of claim 7 , wherein the tines of the first pair of tines are evenly spaced from one another.
9. The heating element of claim 7 , wherein the tines of the first pair of tines are spaced apart by a width.
10. The heating element of claim 9 , wherein the width is greater at an inner region of the heating element adjacent the platform tine portion than the width at an outer region of the heating element adjacent an outer edge of the first side tine portion opposite the inner region.
11. The heating element of claim 2 , wherein the vaporizer device is configured to measure a resistance of the heating element at each of the four legs to control a temperature of the heating element.
12. The heating element of claim 1 , further comprising a heat shield configured to insulate the heating portion from a body of the vaporizer device.
13. The heating element of claim 1 , wherein the vaporizer device further comprises a heat shield configured to surround at least a portion of the heating element and insulate the heating portion from a body of a wick housing configured to surround at least a portion of the wicking element and the heating element.
14. The heating element of claim 1 , wherein the heating portion is folded between the heating portion and the at least two legs to isolate the heating portion from the at least two legs.
15. The heating element of claim 1 , wherein the heating portion further comprises at least one tab that extends from a side of the at least two tines to allow for easier entry of the wicking element to the interior volume of the heating portion.
16. The heating element of claim 15 , wherein the at least one tab extends away from the interior volume at an angle.
17. The heating element of claim 1 , wherein the at least two legs includes a capillary feature, the capillary feature causing an abrupt change in capillary pressure to thereby prevent the vaporizable material from flowing beyond the capillary feature.
18. The heating element of claim 17 , wherein the capillary feature comprises one or more bends in the at least two legs.
19. The heating element of claim 17 , wherein the at least two legs extend at an angle towards the interior volume of the heating portion, the angled at least two legs defining the capillary feature.
20. A vaporizer device comprising:
a reservoir containing vaporizable material;
a wicking element in fluid communication with the reservoir; and
a heating element comprising:
a heating portion comprising at least two tines spaced apart from one another, the at least two tines comprising a first side tine portion, a second side tine portion opposing and approximately parallel to the first side tine portion, and a platform tine portion connecting the first side tine portion with the second side tine portion, the heating portion being preformed to define an interior volume configured to receive the wicking element such that the heating portion secures at least a portion of the wicking element to the heating element, the interior volume defined by the first side tine portion, the second side tine portion, and the platform tine portion, the heating portion being configured to contact at least two separate surfaces of the wicking element; and
at least two legs coupled to the at least two tines and spaced apart from the heating portion, the at least two legs configured to electrically communicate with a power source,
wherein power is configured to be supplied to the heating portion from the power source to generate heat, thereby vaporizing the vaporizable material stored within the wicking element.
