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.

Electronic vaping device

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.

In the non-nicotine electronic vaping device, 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 non-nicotine e-vaping device to: calculate a refill rate at which the non-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 non-nicotine pre-vapor formulation alert in response to determining that the refill rate is less than the threshold refill rate.

Non-nicotine electronic vaping device

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.

Heater of an electronic vaping device

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.

Nicotine electronic vaping device

The method includes first defining a first reservoir and a second reservoir within a housing of a cartridge, the second reservoir being in fluid communication with the first reservoir, inserting at least one first layer of absorbent material within the first reservoir, and arranging a heater and a wick to be in communication with a central channel, the wick being in contact with the absorbent material.

Method of making cartridge including absorbent material with first reservoir and second reservoir

Method of making a heater of an electronic vaping device

The method includes establishing a first fluid gradient through a central passage, the central passage traversing through a first channel, the first channel defining at least one first hole, a housing covering the first channel, a first reservoir being defined between the housing and the first channel, a second reservoir defined between the first channel and the central passage. The method further includes establishing a second fluid gradient through the at least one first hole, through at least a first portion of the second reservoir, and through at least a second portion of a wick, a heater being in communication with the wick and the central passage.

Method of operating an e-vaping device including establishing first fluid gradient and second fluid gradient

The method of making the e-vaping cartridge includes cutting at least one first hole through a first channel, sliding a housing over the first channel, the at least one first hole providing fluid communication between a first reservoir and a second reservoir, the first reservoir being defined between the housing and the first channel, where the second reservoir is defined between the first channel and a central passage traversing through the first channel. The method further includes inserting at least one first layer of absorbent material within the second reservoir, and positioning a heater and a wick in communication with the central passage. Distal ends of the wick contact the at least one first layer of absorbent material, where the 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.
