Abstract
A filament may be provided having enhanced solderability and/or heating characteristics configured for heating a substance to release an airborne scent. In exemplary implementations, the ends of a high-temperature compatible filament may be coated with a metal film having greater solderability and/or conductivity relative to the filament. The coated ends may allow the filament to be incorporated into a heating circuit using low-temperature solder, rather than by using high-temperature solder or clamping. The coated ends may have a lower resistance relative to uncoated portions of the filament such that, when electrical current is passed through the filament, most of the current will flow through the coating at the end portions of the filament concentrating heat emitted by the filament to the uncoated portions.
Claims13
A scent delivery apparatus configured to emit one or more airborne scents in an environment of a user, the apparatus comprising:
- a scent provisioning apparatus comprising:
- a reservoir configured to contain a substance, the substance being configured to release an airborne scent responsive to being heated;
- a capillary disposed at least partially within reservoir, the capillary comprising a tube with a bore configured to draw the substance through a portion of the capillary by way of capillary action;
- and
- a filament comprising a strand of a high-temperature compatible conductive material, the filament including two end portions having a coating thereon, the coating including a material configured to reduce a resistive heating of the two end portions, at least a non-coated portion of the filament being disposed at least partially within the capillary, the filament being configured to heat the substance within the capillary by way of resistive heating provided by passing a current through the filament, wherein the non-coated portion of the filament emits a greater level of heat than the coated two end portions under the same amount of current, such that the non-coated portion facilitates the delivery of the greater level of heat to one or more specific regions within the capillary where the non-coated portion is at least partially disposed;
- wherein the scent delivery apparatus is configured to receive information associated with a level of current to be passed through the filament to control a temperature level of the filament, an intensity of the airborne scent released responsive to heating the substance being controlled based on the temperature level of the filament.
