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,
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 charnel 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.
