Abstract

Claims (34)

1. A cartridge for an e-vaping device, the cartridge comprising:

a housing extending along a longitudinal axis of the cartridge, the housing configured to at least partially enclose a reservoir and a vapor generator configured to draw pre-vapor formulation from the reservoir and to heat the drawn pre-vapor formulation to form a generated vapor, the housing having a tip end and an outlet end, the housing configured to

receive light at the tip end of the housing such that the light is received into a thickness of the housing, and

channel the light from the tip end of the housing to the outlet end of the housing via internal reflection through the thickness of the housing between an inner surface of the housing and an outer surface of the housing; and

emit the channeled light from the outlet end of the housing.

2. The cartridge of claim 1 , further comprising:

an outlet-end insert coupled to the outlet end of the housing, the outlet-end insert including at least one outlet air port configured to be in flow communication with the vapor generator enclosed by the housing, the outlet-end insert configured to direct the generated vapor out of the cartridge through the at least one outlet air port, the outlet-end insert further configured to receive the channeled light emitted from the housing at an interface between the outlet-end insert and the outlet end of the housing and to emit the received channeled light.

3. The cartridge of claim 2 , wherein,

the outlet-end insert is configured to channel the channeled light substantially exclusively through an outlet-end surface of the outlet-end insert, the outlet-end surface extending substantially orthogonally to the longitudinal axis of the cartridge.

4. The cartridge of claim 2 , wherein,

the housing and the outlet-end insert are integral with each other as an individual integral element.

5. The cartridge of claim 1 , wherein,

at least the housing is transparent to visible light in a direction that is substantially orthogonal to the longitudinal axis of the cartridge.

6. The cartridge of claim 1 , further comprising:

a cartridge connector interface that is coupled to the housing at a tip end portion of the housing.

7. The cartridge of claim 6 , wherein the cartridge connector interface and the housing are integral with each other as an individual integral element.

8. An e-vaping device, comprising:

the cartridge of claim 6 ; and

a power supply section coupled to the cartridge via a power supply connector interface that is connected to the cartridge connector interface of the cartridge, the power supply section configured to supply electrical power to the cartridge to cause the vapor generator enclosed by the housing of the cartridge to form the generated vapor.

9. The e-vaping device of claim 8 , further comprising:

a light source included in one of the cartridge and the power supply section, the light source configured to emit light based on electrical power received from the power supply section, the housing configured to receive at least a portion of the light emitted by the light source at the tip end of the housing.

10. The e-vaping device of claim 9 , wherein

the power supply section includes control circuitry configured to activate the light source based on a determination that air is being drawn through at least a portion of the e-vaping device, the control circuitry 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.

11. The e-vaping device of claim 10 , 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 the reservoir,

a determined amount of electrical charge held in the power supply section, and/or

a magnitude of generated vapor that is generated by the vapor generator.

12. The e-vaping device of claim 8 , wherein,

the power supply section includes a housing that is separate from the housing of the cartridge and is opaque to visible light.

13. The e-vaping device of claim 8 , wherein the power supply section and the cartridge are configured to be removably coupled together.

14. The e-vaping device of claim 8 , wherein the power supply section includes a rechargeable battery.
