Abstract: The heating engine control circuit includes a rail converter circuit and a gate driver circuit. The rail converter circuit is configured to convert a power supply voltage into a power signal based on a vaping enable signal, the vaping enable signal being a pulse width modulated signal. The gate driver circuit includes an integrated gate driver. The integrated gate driver is configured to control application of power to a heater of the non-nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

IPC: A24F40/42

Abstract: A nicotine e-vaping device may include a nicotine pod assembly and a device body. The nicotine pod assembly has upstream and downstream ends and is configured to hold a nicotine pre-vapor formulation. The upstream end may define at least one upstream recess, and the downstream end may define at least one downstream recess. The device body defines a through hole configured to receive the nicotine pod assembly. The through hole includes an upstream sidewall and a downstream sidewall. The upstream sidewall may include at least one upstream protrusion, and the downstream sidewall may include at least one downstream protrusion. The at least one upstream protrusion and the at least one downstream protrusion may be configured to engage with the at least one upstream recess and the at least one downstream recess, respectively, so as to retain the nicotine pod assembly within the through hole of the device body.

Abstract: In some example embodiments, a reservoir assembly may include a reservoir and an isolation structure. The reservoir may hold a pre-vapor formulation. The reservoir may include a first fluid port extending through a housing of the reservoir, where the first fluid port may enable fluid communication between the reservoir and an exterior of the reservoir assembly. The reservoir may be coupled to a vaporizer assembly that includes a second fluid port configured to enable fluid communication between the reservoir and vaporizer assembly, or the reservoir may be coupled to a vaporizer connector assembly that includes a second fluid port configured to enable fluid communication between the reservoir and an exterior through the vaporizer connector assembly. The isolation structure may move in relation to the reservoir and the vaporizer connector assembly to a position where it exposes one of the fluid ports and covers the other.

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.
