Electronic vaping device with outlet-end illumination
First Claim
1. A cartridge for an e-vaping device, the cartridge comprising:
- an inner tube defining an inner longitudinal boundary of a reservoir that is annular and cylindrical, the reservoir configured to hold a pre-vapor formulation;
a vapor generator configured to draw the pre-vapor formulation from the reservoir and to heat the drawn pre-vapor formulation to form a generated vapor;
a housing extending along a longitudinal axis of the cartridge, the housing at least partially enclosing the reservoir and the vapor generator such that the housing defines an outer longitudinal boundary of the reservoir, the housing having a tip end and an outlet end, the housing configured toreceive light at the tip end of the housing such that the light is received into a thickness of the housing, andchannel 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
an outlet-end insert coupled to the outlet end of the housing, the outlet-end insert including at least one outlet air port in flow communication with the vapor generator, 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 emit the channeled light.

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.

5. An e-vaping device, comprising:
-
a cartridge, the cartridge including, an inner tube defining an inner longitudinal boundary of a reservoir that is annular and cylindrical, the reservoir configured to hold a pre-vapor formulation, a vapor generator configured to draw the pre-vapor formulation from the reservoir and to heat the drawn pre-vapor formulation to form a generated vapor, a housing extending along a longitudinal axis of the cartridge, the housing at least partially enclosing the reservoir and the vapor generator such that the housing defines an outer longitudinal boundary of the reservoir, 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, an outlet-end insert coupled to the outlet end of the housing, the outlet-end insert including at least one outlet air port in flow communication with the vapor generator, 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 emit the channeled light, and a cartridge connector interface that is coupled to the housing; and a power supply section coupled to the cartridge via a power supply connector interface that is connected to the cartridge connector interface, the power supply section configured to supply electrical power to the cartridge to cause the vapor generator to form the generated vapor. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A method for operating an e-vaping device, the method comprising:
-
determining whether at least a threshold flow of air is being drawn through at least an outlet-end insert of the e-vaping device; and controlling a light source of the e-vaping device to emit light through an interior of the e-vaping device in response to determining that at least the threshold flow of air is being drawn through at least the outlet-end insert of the e-vaping device, such that the light is transmitted through a thickness of a housing of the e-vaping device to the outlet-end insert such that the housing channels the light from a tip end of the housing to an 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 the outlet-end insert emits the channeled light. - View Dependent Claims (16, 17, 18, 19)
