wherein the outer rim includes an aperture through which the connecting portion of the heating element is configured to pass through.
2. The atomizer assembly of claim 1 , wherein the outer wall further comprises a base positioned approximately perpendicular to the two opposing short sides and the two opposing long sides, the base at least partially defining the internal volume.
3. The atomizer assembly of claim 2 , wherein the base comprises one or more slots, wherein air pressure caused by a flow of vaporizable material within the heating portion is configured to escape through the one or more slots.
4. The atomizer assembly of claim 2 , wherein the connecting portion includes a retainer portion configured to bend around the base to secure the heating element to the wick housing, and wherein the base includes an aperture configured to receive the retainer portion of the connecting portion.
5. The atomizer assembly of claim 2 ,
wherein the connecting portion extends out of the opening and over the outer wall, and wherein the wicking element is configured to pass through the opening.
6. The atomizer assembly of claim 1 , wherein an outer surface of the wick housing includes a recessed channel for securing the connecting portion of the heating element, the recess channel aligning with the aperture.
7. An atomizer assembly for a vaporizer cartridge, the vaporizer cartridge configured to be coupled to a vaporizer body of a vaporizer device, the atomizer assembly comprising:
a wick housing comprising a base, an opening, an outer rim surrounding and extending away from the opening, and an outer wall at least partially defining an internal volume configured to receive a wicking element and at least a heating portion of a heating element, the heating element also comprising a connecting portion configured to extend out of the internal volume and over the outer wall such that the outer wall is positioned between the heating portion and the connecting portion, the outer wall comprising two opposing short sides and two opposing long sides, each of the two opposing long sides having formed therein a recess configured to releasably couple the vaporizer cartridge to a corresponding feature of the vaporizer body;
wherein the outer wall comprises a capillary feature, the capillary feature comprises a curved surface formed at an intersection between the outer rim and at least one of two opposing long sides of the base.
8. The atomizer assembly of claim 7 , wherein the curved surface has a radius that is sufficient to break tangency points between an outer surface and the outer rim.
9. The atomizer assembly of claim 7 , wherein the capillary feature is configured to cause an abrupt change in capillary pressure between the heating element and the wick housing to thereby prevent a vaporizable material from flowing beyond the capillary feature.
10. The atomizer assembly of claim 7 , wherein the capillary feature is positioned within a cutout in the outer wall, the cutout configured to space the heating element from the outer wall, thereby preventing excess heat from contacting the outer wall.
11. The atomizer assembly of claim 1 , wherein at least one of the two opposing short sides comprises a chip recess configured to receive an identification chip.
12. The atomizer assembly of claim 11 , wherein the chip recess comprises at least two walls configured to surround and retain the identification chip.
13. The atomizer assembly of claim 1 , wherein the recess is positioned proximate to an intersection between a long side of the two opposing long sides and a short side of the two opposing short sides.
14. The atomizer assembly of claim 1 , wherein each of the two opposing long sides includes two recesses.
15. A method of forming an atomizer assembly for a vaporizer device, the method comprising:
coupling a heating element to a wick housing configured to surround a heating portion of the heating element, the wick housing comprising:
an outer wall comprising two opposing short sides and two opposing long sides, the two opposing long sides having formed therein a recessed channel configured to receive a connecting portion of the heating element,
a base positioned approximately perpendicular to the two opposing short sides and the two opposing long sides,
an internal volume formed by the outer wall and the base, the internal volume surrounding the heating portion of the heating element, and
an opening opposite the base, and
an outer rim surrounding and extending away from the opening, wherein the outer rim includes an aperture through which the connecting portion of the heating element passes though.
16. The method of claim 15 , wherein the coupling includes sliding the connecting portion of the heating element in the recessed channel formed in the outer wall of the wick housing.
17. An atomizer assembly for a vaporizer cartridge, the atomizer assembly comprising:
a wick housing comprising an opening, an outer rim surrounding and extending away from the opening, and an outer wall at least partially defining an internal volume configured to receive a wicking element and at least a heating portion of a heating element, the heating element also comprising a connecting portion configured to extend out of the internal volume and over the outer wall such that the outer wall is positioned between the heating portion and the connecting portion, the outer wall comprising two opposing short sides and two opposing long sides;
wherein the outer rim includes an aperture through which the connecting portion of the heating element is configured to pass through.
18. The atomizer assembly of claim 17 , wherein each of the two opposing long sides having formed therein a recess configured to releasably couple the vaporizer cartridge to a corresponding feature of a vaporizer body.
