Abstract: A reservoir assembly that holds a nicotine pre-vapor formulation in a reservoir includes a reservoir assembly connector assembly defining a connector conduit, and which may be configured to detachably couple with a nicotine vaporizer assembly based on a connector element of the nicotine vaporizer assembly engaging with the connector conduit of the connector conduit. The reservoir assembly may include an isolation structure configured to move in relation to both the reservoir and the nicotine vaporizer connector assembly between a first position where the isolation structure exposes the nicotine vaporizer assembly to the reservoir and at least partially obstructs the connector conduit to restrict the connector element from disengaging from the connector conduit, and a second position where the isolation structure isolates the nicotine vaporizer assembly from the reservoir and opens the connector conduit to enable the connector element to disengage from the connector conduit.

Abstract: A heater system for a non-combustible aerosol-generating device includes a heater element and a fuse element. The heater element has a heating region, a first terminal and a second terminal. The fuse element is electrically connected between the first terminal and the second terminal in parallel with the heater element. The fuse element has a region configured to induce a localized hot spot to cause the fuse element to open circuit in response to power applied between the first terminal and the second terminal.

Abstract: An e-vapor device may include a cartridge configured to hold a pre-vapor formulation therein. The e-vapor device may additionally include a dispensing body including a ratchet assembly and configured to receive a vaporizer to interact with the ratchet assembly. The vaporizer is configured to access the pre-vapor formulation in the cartridge via a coupling action and to heat the pre-vapor formulation to generate a vapor. The ratchet assembly is configured to undergo a mechanical incrementation with each coupling action to facilitate a simultaneous removal of the cartridge with the vaporizer coupled thereto after a designated number of coupling actions. Accordingly, the overuse of the vaporizer and the adverse sensory effects associated therewith can be reduced or prevented.

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.

Abstract: An aerosol-generating device includes a sensor configured to detect puffs; and processing circuitry configured to cause the aerosol-generating device to increase a temperature of a heater to a preheat temperature, decrease the temperature of the heater to a first heating temperature before a first detected puff of the detected puffs, the first heating temperature being below the preheat temperature, and increase the temperature of the heater based on a number of the detected puffs.

Abstract: The cartridge includes a first tube extending longitudinally, the first tube at least partially defining an air passage within the cartridge, a vapor generator in communication with a first portion of the air passage, a first air inlet defined by the cartridge, the first air inlet being in communication with a second portion of the air passage, the second portion being upstream of the vapor generator relative to a normal direction of an airflow through the air passage during an operational use of the cartridge, and a dilution air passage defined by the cartridge, a discharge end of the dilution air passage intersecting a third portion of the air passage, the third portion being downstream of the vapor generator relative to the normal direction of the airflow.

Abstract: A method of controlling a hot wire anemometer (HWA) of a nicotine e-vaping device includes controlling, by a first PID controller, a level of power applied by the nicotine e-vaping device to the HWA based on a temperature of a heated element of the HWA and a temperature setpoint; generating a puff detection signal indicating whether or not a puff is currently occurring with respect to the nicotine e-vaping device; and while the puff detection signal indicates that a puff is not currently occurring with respect to the nicotine e-vaping device, detecting, by a second PID controller, a change in an ambient temperature of the HWA, and controlling, by the second PID controller, the temperature setpoint such that the temperature setpoint changes in response to the detected change in the ambient temperature of the HWA.

Abstract: A cooldown system for a device includes at least one processor and a memory coupled to the at least one processor. The memory is configured to store instructions. The at least one processor is configured to execute the instructions to cause the cooldown system to detect when a session has ended, activate a cooldown timer to measure a cooldown time, provide an indication of a remaining time of the cooldown timer, and in response to the cooldown timer elapsing, return the device to normal operation.
