ELECTRONIC CIGARETTE
A heating device for an electronic smoking apparatus has a heating element encased in a bulb so that e-liquid does not come in contact with the heating element, but rather is heated indirectly by the bulb. The heating element is in electrical communication with electrical contacts exterior of the bulb, which contacts are placed in electrical communication with a power source such as a batter. The bulb can be made of glass, quartz, or similar inert silica-based compositions. The bulb can be shaped and sized to accommodate the components of a variety of electronic smoking apparatus. The bulb includes an indentation or an external protrusion that functions as a reservoir to receive and retain inhalant material such as liquids, concentrates or herbal material.
1 . A heating device for an electronic smoking apparatus, comprising:
a heating element disposed and encased inside a bulb, wherein a portion of the heating element is exposed exterior of the bulb, the portion delimiting at least one electrical contact; and
the bulb including a reservoir configured to receive and retain an inhalant material.
2 . The heating device of claim 1 , wherein the reservoir comprises an indentation in the surface of the bulb.
3 . The heating device of claim 1 , wherein the reservoir comprises a protrusion extending from the surface of the bulb.
4 . The heating device of claim 1 , wherein the bulb comprises glass, quartz, or combinations thereof.
5 . The heating device of claim 1 , wherein the heating element comprises a wire.
6 . The heating device of claim 1 , wherein the heating element comprises a coil.
7 . The heating device of claim 1 , wherein the heating element comprises a ribbon.
8 . The heating device of claim 1 , wherein the bulb comprises beveled ends.
9 . The heating device of claim 1 , wherein the heating element extends from both ends of the bulb, thereby delimiting an anode and a cathode.
10 . The heating device of claim 1 , further comprises a sealing element sealing the heating element inside the bulb.
11 . The heating device of claim 1 , wherein the electrical contact is flush with an end of the bulb.
12 . The heating device of claim 11 , wherein a magnetic connector is disposed about the electrical contact.
13 . A heating device for an electronic smoking apparatus, comprising an elongated bulb configured to receive and retain therein a heating element.
14 . The heating device of claim 13 , including a through-bore disposed lengthwise through the bulb, the through-bore configured to receive and retain therein the heating element.
15 . The heating device of claim 13 , wherein the bulb includes an indentation, the indentation comprising a reservoir to receive and retain inhalant material.
16 . The heating device of claim 13 , wherein the bulb includes a protrusion, the protrusion comprising a reservoir to receive and retain inhalant material.
17 . The heating device of claim 13 , wherein the bulb is substantially cylindrical in shape.
18 . The heating device of claim 13 , wherein the bulb comprises glass, quartz, or combinations thereof
