Abstract: An aerosol-generating device includes a housing that defines a capsule-receiving cavity, a lid configured to close the housing, and a replaceable mouthpiece coupleable to the lid such that air entering the housing and drawn through the capsule-receiving cavity exits out of the mouthpiece. The lid may be fixedly coupled to the housing at a first point and releasably coupleable to the housing at a second point. The capsule-receiving cavity may have a first end having a first width, and a second end have a second width that is different from the first width. The capsule-receiving cavity may be tapered between the first end and the second end. The mouthpiece may be coupleable to the first end. One or more alignment member may be disposed at or towards the second end. The alignment members may include seals and/or electrical connections and/or flat surfaces and/or angled surfaces.

Abstract: A nicotine e-vaping device may include a device body configured to receive a nicotine cartridge. The nicotine cartridge includes a nicotine pre-vapor formulation, a wick, and an integral heater-thermocouple. The wick is configured to transport the nicotine pre-vapor formulation by capillary action. The integral heater-thermocouple includes a first segment made of a first alloy and a second segment made of a second alloy. The device body includes a power supply, at least one sensor, and a controller. The power supply is configured to deliver electrical energy to the integral heater-thermocouple to heat the nicotine pre-vapor formulation to generate a nicotine vapor. The at least one sensor is configured to measure a voltage difference between the first segment and the second segment of the integral heater-thermocouple during such heating. The controller is configured to adjust the electrical energy to the integral heater-thermocouple based on the measured voltage difference.

Abstract: A nicotine e-vaping device may include a nicotine pod assembly and a device body defining a through hole configured to receive the nicotine pod assembly. The nicotine pod assembly is configured to hold a nicotine pre-vapor formulation. The through hole of the device body includes at least sidewall that is configured to deflect during an insertion of the nicotine pod assembly. One or more sidewalls of the through hole may include at least one protrusion configured to engage with corresponding recesses of the nicotine pod assembly so as to retain the nicotine pod assembly within the through hole of the device body.

Abstract: A non-nicotine e-vaping device may include a non-nicotine pod assembly and a device body. The non-nicotine pod assembly has upstream and downstream ends and is configured to hold a non-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 non-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 non-nicotine pod assembly within the through hole of the device body.

Abstract: A capsule may include a housing, an aerosol-forming substrate, and a heater. The housing defines inlet openings, outlet openings, and a chamber between the inlet openings and the outlet openings. The chamber may have a longest dimension extending from at least one of the inlet openings to a corresponding one of the outlet openings. The aerosol-forming substrate is within the chamber of the housing. The heater is embedded in the housing. The heater includes a first end section, an intermediate section, and a second end section. The intermediate section is disposed within the aerosol-forming substrate in the chamber. An aerosol-generating device may include a device body with a lid configured to open to permit an insertion of the capsule and configured to close to engage the capsule within the device body.

Abstract: A capsule for an aerosol-generating device may include a first heater, a second heater, and a frame sandwiched between the first heater and the second heater. The frame may define open spaces therein and have a rigidity that is adequate to support the first heater and the second heater. The open spaces within the frame may be interconnected and sized for aerosol-permeability and capillary action. A nicotine-containing material, such as tobacco, may be disposed within the capsule.

Abstract: A non-combustible aerosol-generating device includes a capsule, a memory and a controller. The capsule includes an aerosol-forming substrate and a heater configured to heat the aerosol-forming substrate. The controller is configured to execute computer-readable instructions stored in the memory to cause the non-combustible aerosol-generating device to: apply power to the heater during a preheat interval, record one or more heating characteristic waveforms resulting from application of the power to the heater during at least a portion of the preheat interval, and determine whether the capsule is valid based on one or more of the heating characteristic waveforms.

Abstract: A non-combustible aerosol-generating device includes a memory storing computer-readable instructions and a controller. The controller is configured to execute the computer-readable instructions to cause the non-combustible aerosol-generating device to: apply power to a heater to preheat an aerosol-forming substrate; determine whether a preheat monitor timer has exceeded a preheat timer threshold; determine whether the aerosol-forming substrate has been previously heated based on a comparison between a first threshold power level and an applied power to the heater in response to the preheat monitor timer having not exceeded the preheat timer threshold; and determine whether the aerosol-forming substrate has been previously heated based on a comparison between a second threshold power level and the applied power to the heater in response to the preheat monitor timer having exceeded the preheat timer threshold.
