Electronic vaporizer cartridge with encased heat source
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.
1. A cartridge for an electronic smoking device, comprising:
a housing, a mouthpiece, and a connector element, the mouthpiece extending upward from a top of the housing and the connector element extending from a bottom of the housing;
an air flow tube disposed in the housing and defining an air flow passageway through the housing, the air flow tube comprising quartz-encased metal;
an internal storage area disposed between the airflow tube and the housing, wherein the internal storage area is configured to retain inhalant material;
a compartment extending from the air flow tube, the compartment containing a heat source, the heat source comprising a metal heating element encased inside a bulb; and
wherein the heat source is electrically coupled to the connector element, wherein the connector element is configured to transmit electrical current from a power source to the heat source.
2. The cartridge of claim 1 , wherein the housing comprises glass, quartz, or ceramic.
3. The cartridge of claim 1 , wherein the bulb comprises glass, quartz, or ceramic.
4. The cartridge of claim 1 , wherein the air flow tube comprises a metal tube core surrounded by a concentrically disposed quartz encasement.
5. The cartridge of claim 1 , wherein the connector element includes one or more apertures in air flow communication with the air flow passageway.
6. The cartridge of claim 1 , wherein the mouthpiece is in air flow communication with the air flow passageway.
7. An electronic smoking device, comprising:
a cartridge and a control section;
the control unit comprising a power supply and an attachment point;
the cartridge comprising:
a housing, a mouthpiece, and a connector element, the mouthpiece extending upward from a top of the housing and the connector element extending from a bottom of the housing;
an air flow tube disposed in the housing and defining an air flow passageway through the housing, the air flow tube comprising quartz-encased metal;
an internal storage area disposed between the airflow tube and the housing, wherein the internal storage area is configured to retain inhalant material;
a compartment extending from the air flow tube, the compartment containing a heat source, the heat source comprising a heating element encased inside a bulb; and
the heat source electrically coupled to the connector element,
wherein the connector element of the cartridge is removably connected to the attachment point of the control unit such that the power supply of the control unit transmits electrical current to the heat source through the connector element.
8. The electronic smoking device of claim 7 , wherein the housing comprises glass, quartz, or ceramic.
9. The electronic smoking device of claim 7 , wherein the bulb comprises glass, quartz, or ceramic.
