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.

First claim

The invention claimed is:

1. An e-vaping device, comprising:
a light source configured to emit light; and
control circuitry configured to control the light source, wherein the controlling includes
activating the light source to emit light through an interior of the e-vaping device based on a determination that air is being drawn through at least a portion of the e-vaping device, such that
at least a portion of the light is channeled along a longitudinal axis of the e-vaping device through a thickness of a first housing of the e-vaping device to an outlet end of the first housing, via internal reflection through the thickness of the first housing between an inner surface of the first housing and an outer surface of the first housing, and
the channeled light is emitted from the outlet end of the first housing.

2. The e-vaping device of claim 1 , wherein the control circuitry is further configured to cause the light source to remain activated for at least a particular period of elapsed time following a cessation of air being drawn through at least the portion of the e-vaping device.

3. The e-vaping device of claim 2 , wherein,
the light source is configured to emit light having a particular property, the particular property being a color of the light and/or a brightness of the light; and
the control circuitry is further configured to control the particular property of the light emitted by the light source, based on,
a determination that the light source has emitted light for at least a threshold period of elapsed time,
a determined amount of pre-vapor formulation held in a reservoir of the e-vaping device,
a determined amount of electrical charge held in a power supply section of the e-vaping device, and/or
a magnitude of generated vapor that is generated by a vapor generator of the e-vaping device.

4. The e-vaping device of claim 1 , wherein,
at least the first housing is transparent to visible light in a direction that is substantially orthogonal to the longitudinal axis of the e-vaping device.

5. The e-vaping device of claim 1 , wherein,
the control circuitry is located within a second housing of the e-vaping device,
the second housing is separate from the first housing, and
the second housing is opaque to visible light.

6. A method for operating an e-vaping device, the method comprising:
controlling a light source of the e-vaping device, wherein the controlling includes
activating the light source to emit light through an interior of the e-vaping device based on a determination that air is being drawn through at least a portion of the e-vaping device, such that
at least a portion of the light is channeled along a longitudinal axis of the e-vaping device through a thickness of a first housing of the e-vaping device to an outlet end of the first housing, via internal reflection through the thickness of the first housing between an inner surface of the first housing and an outer surface of the first housing, and
the channeled light is emitted from the outlet end of the first housing.

7. The method of claim 6 , wherein,
the light source is configured to emit light having a particular property, the particular property being a color of the light and/or a brightness of the light; and
the controlling includes controlling the particular property of the light emitted by the light source, based on,
a determination that the light source has emitted light for at least a threshold period of elapsed time,
a determined amount of pre-vapor formulation held in a reservoir of the e-vaping device,
a determined amount of electrical charge held in a power supply section of the e-vaping device, and/or
a magnitude of generated vapor that is generated by a vapor generator of the e-vaping device.

8. The method of claim 6 , wherein,
at least the first housing is transparent to visible light in a direction that is substantially orthogonal to the longitudinal axis of the e-vaping device.

9. The method of claim 6 , wherein,
the e-vaping device includes a second housing that is separate from the first housing, and
the second housing is opaque to visible light.
