Abstract

A vapor generator assembly for an e-vaping device may include a reservoir configured to hold a pre-vapor formulation, a vaporizer assembly configured to heat pre-vapor formulation drawn from the reservoir to form a vapor, and an air intake assembly configured to direct ambient air into the vaporizer assembly. The air intake assembly may at least partially define an air inlet that extends at least partially around an outer surface of the vapor generator assembly. The air inlet may be an arcuate air inlet or an annular air inlet. The air intake assembly may at least partially define an inlet channel extending from the air inlet into an interior of the vapor generator assembly to at least partially establish fluid communication between the arcuate air inlet and the vaporizer assembly. The inlet channel may extend coaxially in relation to a longitudinal axis of the vapor generator assembly.

First claim

What is claimed is:

1 . A vapor generator assembly for an e-vaping device, the vapor generator assembly comprising:
a vaporizer assembly configured to heat pre-vapor formulation to form a vapor; and an air intake assembly configured to direct ambient air into the vaporizer assembly, the air intake assembly at least partially defining
an arcuate air inlet that extends at least partially around an outer surface of the vapor generator assembly, and
a paraxial inlet channel extending paraxially in relation to a longitudinal axis of the vaporizer assembly from the arcuate air inlet into an interior of the vapor generator assembly, wherein the air intake assembly is configured to establish fluid communication between the arcuate air inlet and the vaporizer assembly via at least the paraxial inlet channel.

2 . The vapor generator assembly of claim 1 , wherein the arcuate air inlet is at least partially defined by an arcuate gap between the air intake assembly and an outer housing of the vapor generator assembly.

3 . The vapor generator assembly of claim 1 , wherein the arcuate air inlet is an annular air inlet that extends around an entirety of the outer surface of the vapor generator assembly.

4 . The vapor generator assembly of claim 1 , wherein the air intake assembly includes
an adjustment ring structure through which an orifice extends, the adjustment ring structure surrounding at least a portion of the vaporizer assembly, the adjustment ring structure configured to rotate around the longitudinal axis to adjustably align the orifice with an inlet port of the vaporizer assembly to adjustably control a cross-sectional flow area of fluid communication between the arcuate air inlet and the vaporizer assembly, and a structural element that defines
a first outer surface that at least partially defines the arcuate air inlet, and
a second outer surface that is exposed to an exterior of the vapor generator assembly and is configured to be physically manipulated from the exterior of the vapor generator assembly to cause the intake air assembly to rotate around the longitudinal axis,
wherein an outer surface of the adjustment ring structure and an inner surface of the structural element at least partially define an arcuate inlet channel between the arcuate air inlet and the orifice, the arcuate inlet channel at least partially surrounding the adjustment ring structure, and wherein the air intake assembly is configured to establish adjustable fluid communication between the arcuate air inlet and the vaporizer assembly via the paraxial inlet channel, the arcuate inlet channel, and the orifice.

5 . An e-vaping device, comprising:
the vaporizer generator assembly of claim 4 ; and a power supply assembly detachably coupled to the vaporizer generator assembly, the power supply assembly configured to supply electrical power to the vaporizer assembly, wherein the power supply assembly includes an outer housing, and at least one inner surface of the outer housing of the power supply assembly at least partially defines an outer radial boundary of the arcuate inlet channel, such that the arcuate inlet channel is at least partially defined within an interior of the e-vaping device by respective surfaces of the adjustment ring structure of the air intake assembly, the structural element of the air intake assembly, and the outer housing of the power supply assembly.

6 . The e-vaping device of claim 5 , wherein the arcuate air inlet is at least partially defined by an arcuate gap between the air intake assembly and an outer housing of the e-vaping device.

7 . The e-vaping device of claim 5 , wherein the arcuate air inlet is an annular air inlet that extends around an entirety of the outer surface of the e-vaping device.

8 . The e-vaping device of claim 5 , wherein the power supply assembly includes a rechargeable battery.
