Abstract
A method of forming a heater assembly of an e-vaping device includes bending a wire to form a first lobe and bending the wire to form a second lobe. The first lobe and the second lobe form a generally sinuously-shaped heater having a first set of lobes and a second set of lobe. A first apex of the first lobe is generally opposite a second apex of the second lobe. The method may also include curling the first set of lobes towards the second set of lobes to form a heater having a substantially tubular form. The heater defines an opening there through.
Claims15
An e-vaping device comprising:
- a housing;
- a reservoir in the housing;
- a heater in the housing, the heater including,
- a first set of lobes, and
- a second set of lobes opposite the first set of lobes, the heater having a generally tubular cross-section defining a channel therein, the first set of lobes curled towards the second set of lobes, apexes of the first set of lobes not in physical contact with apexes of the second set of lobes, the heater being formed of an electrically resistive wire, the first set of lobes being spaced about 0.25 mm to about 1.0 mm from the second set of lobes, each lobe of the first set of lobes and each lobe of the second set of lobes having a U-shape, and an inner width of the U-shape ranging from about 0.25 mm to about 1.0 mm;
- and
- a power supply configured to supply power to the heater.
