An e-vapor device may include a pre-vapor sector and a heater structure arranged in thermal contact with the pre-vapor sector. The pre-vapor sector includes a reservoir and a dispensing interface. The pre-vapor sector is configured to hold and dispense a pre-vapor formulation. The heater structure is configured to vaporize the pre-vapor formulation to generate a vapor. The heater structure includes a base wire and a heater wire coiled around the base wire. The base wire is insulated from the heater wire. As a result of the heater design, the heater structure is stiffer and more robust than other related heaters in the art, thus allowing more options for its implementation.

An electronic smoking article includes an outer tube extending in a longitudinal direction, an inner tube within the outer tube and including a pair of opposing slots, a liquid supply comprising a liquid material, a coil heater, a wick and a mouth end insert. The coil heater is located in the inner tube. The coil heater is formed of an iron-free, nickel-chromium alloy and has substantially uniformly spaced windings. The wick is surrounded by the coil heater such that the wick delivers liquid material to the coil heater and the coil heater heats the liquid material to a temperature sufficient to vaporize the liquid material and form an aerosol in the inner tube.

An electric heater includes a substrate (an insulating material capable of forming a conductor pattern on a surface of an insulating substrate), a first plane heating element formed on one surface of the substrate, and a second plane heating element formed on one surface of the substrate to be located outside the first plane heating element. The first plane heating element includes a first pattern portion connecting a start point with an end point located in a first zone, a pair of first electrodes located outside the first zone, and a pair of first connectors connecting the first pattern portion with the first electrodes. The second plane heating element includes a second pattern portion located in a second zone surrounding the first zone and connecting a start point with an end point, and at least some of the first connectors are located in the second zone.

A heating element (18) for a heating element carrier (10) of an electrically operated heat gun (100). The heating element carrier (10) is designed to receive the heating elements (18). The heating elements comprise a resistance wire (34) with a cross-sectional surface A and a cross-sectional perimeter U, where (4πA)U2<1.

A portable space heater is provided having a heating assembly that includes at least one heating element positioned in front of a fan (defined by the direction of the air flow with the air blowing toward the front) such that the heating element is in linear alignment with the fan along the axis of rotation of the fan. The fan and the at least one heating element may be further positioned within a duct assembly that narrows as it approaches a front grill of the portable space heater.
