Abstract: A cartridge for an e-vaping device includes a housing extending along a longitudinal axis of the cartridge, and an outlet-end insert coupled to the outlet end of the housing. The housing at least partially encloses a pre-vapor formulation reservoir and a vapor generator of the cartridge and further channels light via internal reflection through an interior of the housing. The outlet-end insert includes an outlet in flow communication with the vapor generator, directs the vapor generated by the vapor generator out of the cartridge through the outlet, and further emits the light channeled through the interior of the housing. One or more properties of the light are controllable.

Abstract: A power supply assembly for an e-vaping device may include a coupling interface configured to couple with a cartridge to configure the e-vaping device to generate a vapor, a light-emitting device, and a light tube structure extending from the light-emitting device and through the coupling interface. The light tube structure may channel light emitted by the light-emitting device to emit the light into a reservoir of the cartridge to cause at least one portion of the cartridge to emit at least a portion of the channeled light to an external environment.

Abstract: A saturation sensor measures at least one electrical characteristic of the wick between the heating element and the probe wire at a first time and a second time, wherein the at least one electrical characteristic includes a resistance, a capacitance, or both a resistance and a capacitance. Control circuitry is configured to cause the nicotine e-vaping device to: calculate a refill rate at which the nicotine pre-vapor formulation flows onto the wick based on the at least one electrical characteristic at the first time and the at least one electrical characteristic at the second time; determine that the refill rate is less than a threshold refill rate; and output a low nicotine pre-vapor formulation alert in response to determining that the refill rate is less than the threshold refill rate.

Abstract: The replaceable mouthpiece includes a body having a first body end and a second body end. The first body end defines an outlet. The second body end defines a first opening coupleable to the aerosol-generating device. The replaceable mouthpiece includes two or more pillars disposed within the body and extending towards the second end.

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.

Abstract: The e-vaping cartridge includes a housing, a first tube extending in a longitudinal direction within the housing, the first tube defining at least one first hole that provides fluid communication between a first annulus reservoir and a second annulus reservoir, the first annulus reservoir defined between the housing and the first tube, the second annulus reservoir defined between the first tube and a central passage traversing through the first tube. At least one first layer of absorbent material is positioned within the second annulus reservoir. A wick is in communication with the central passage, where distal ends of the wick contact the at least one first layer of absorbent material. A heater is configured to vaporize a pre-vapor formulation that is communicated by the wick from the at least one first layer of absorbent material. The device includes the cartridge.

Abstract: The e-vaping cartridge includes a housing body with a first tube extending longitudinally within the housing body and defining a central passage, the first tube further defining at least one first hole. One or more layers of absorbent material are positioned within an inner annulus reservoir around at least a portion of the first tube. A wick is in communication with the central passage where distal ends of the wick traverse the first hole and is in communication with an annulus reservoir. A heater is configured to vaporize a pre-vapor formulation communicated to the wick from the annulus reservoir. The e-vaping device includes the cartridge which is connectable to a power section.
