Abstract: A cartridge for an electronic smoking device includes a heat source comprising a bulb-encased heating element. The heat source is disposed inside a compartment of the cartridge. The compartment extends from an air flow tube. The housing includes a storage area for retaining inhalant material. The cartridge includes a threaded connector that attaches to a control unit that has a power supply such as a batter. The cartridge avoids direct contact between the inhalant material and any metal components of the cartridge by either eliminating metal components or by encasing the metal components in glass, quartz, or ceramic.

Abstract: 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.
