Abstract
In an example embodiment, a heater assembly for an electronic heating device includes a heating element and a support. The heating element includes a planar portion, a first lead, and a second lead. The planar portion includes a filament. The filament defines an air channel through the planar portion. The filament includes a plurality of curves. At least one of the curves has a tip thereon. At least one of the first lead portion, the second lead portion, or both the first lead portion and the second lead portion are generally coplanar with the planar portion of the heating element. The heating element is in contact with the support such that the tip of the at least one of the curves rests thereon.
Claims39
A heater assembly comprising:
- a heating element including,
- a planar portion including a filament, the filament defining an air channel through the planar portion, the filament arranged so as to form a plurality of curves, each of the curves having a closed end, an open end, and a tip extending away from the air channel thereon, the tip of each of the curves extending from the closed end thereof,
- an elongated body extending outwardly from the tip of each of the curves, the elongated body extending perpendicular to a width of the tip, and a width of the elongated body being greater than the width of the tip,
- a first lead portion, and
- a second lead portion, at least one of the first lead portion, the second lead portion, or both the first lead portion and the second lead portion being coplanar with the planar portion of the heating element;
- and
- a support, the heating element in contact with the support such that the tip of each one of the curves rests thereon.
A cartridge for an e-vapor device, comprising:
- a housing;
- a reservoir in the housing;
- a transfer material adjacent a portion of the reservoir;
- and
- a heater assembly including,
- a heating element, the heating element including,
- a planar portion including a filament, the filament defining an air channel through the planar portion, the filament arranged so as to form a plurality of curves, each of the curves having a closed end, an open end, and a tip extending away from the air channel thereon, the tip of each of the curves extending from the closed end thereof,
- an elongated body extending outwardly from the tip of each of the curves, the elongated body extending perpendicular to a width of the tip, and a width of the elongated body being greater than the width of the tip,
- a first lead portion, and
- a second lead portion, at least one of the first lead portion, the second lead portion, or both the first lead portion and the second lead portion being coplanar with the planar portion of the heating element;
- and a support, the heating element in contact with the support such that the tip of each of the curves rests thereon.
