A saturation sensor measures at least one electrical characteristic of the wick between the heating element and the probe wire at a first time and a second time, wherein the at least one electrical characteristic includes a resistance, a capacitance, or both a resistance and a capacitance. Control circuitry is configured to cause the nicotine e-vaping device to: calculate a refill rate at which the nicotine pre-vapor formulation flows onto the wick based on the at least one electrical characteristic at the first time and the at least one electrical characteristic at the second time; determine that the refill rate is less than a threshold refill rate; and output a low nicotine pre-vapor formulation alert in response to determining that the refill rate is less than the threshold refill rate.

An inductively heatable susceptor for use with an inductively heated aerosol-generating device or system includes an open-porous inductively heatable ceramic material configured to hold an aerosol-forming liquid and configured to heat the aerosol-forming liquid under the influence of an alternating electromagnetic field. A cartridge for use with an aerosol-generating device includes an aerosol-forming liquid and a susceptor. An aerosol-generating device includes a susceptor.

An atomizer for an electronic cigarette and an electronic cigarette are presented. The atomizer comprises a substrate, a heating device and a cover member. The substrate is provided with a mounting space. One end of the heating device is inserted into the mounting space and partially extends to the outside through the substrate to form a controlling member, and the other end is exposed to the outer surface of the substrate. When the controlling member is pressed into the substrate by an external pressing force, the heating device is pushed to move toward the outside of the substrate along the mounting space and partially extends out of the substrate. The cover member is detachably mounted to the substrate and covers the controlling member. The technical solution of the present invention is convenient for the user to disassemble and replace the heating device inside the atomizer, effectively saving the use cost.

A composite heat source for use in a smoking article is provided, including a non-combustible porous ceramic matrix; and a particulate combustible fuel embedded within the non-combustible porous ceramic matrix. The non-combustible porous ceramic matrix is formed from one or more particulate materials having a median D50 particle size at least five times less than the median D50 particle size of the particulate combustible fuel. Preferably, the non-combustible porous ceramic matrix includes one or more transition metal oxides.

A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes: a refillable PV that is removable from the case; an electrical power source for re-charging a rechargeable battery in the PV; a user-replaceable reservoir for holding e-liquid; and an electrical or electronic pump adapted to transfer e-liquid from the reservoir to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the case has closed and open positions, and lifts up the removable PV when in the open position to enable a user to readily withdraw the PV from the case.

There is provided an aerosol-generating article including a tobacco plug, a mouthpiece positioned downstream of the tobacco plug, and a resistive heating element positioned within the tobacco plug. The resistive heating element includes an upstream portion protruding from an upstream end of the tobacco plug, wherein the upstream portion of the resistive heating element includes at least two heater electrical contacts configured to receive a supply of electrical energy from at least two device electrical contacts when the aerosol-generating article including the resistive heating element is inserted into an aerosol-generating device.

A cartridge for use in a vapor provision system includes an inner container holding a reservoir of fluid to be vaporized, and an outer housing having a mouthpiece formed therein, wherein the outer housing extends in a longitudinal direction along the outside of the inner container for at least a substantial portion of the inner container. The inner container and outer housing are provided with a latch mechanism to retain the inner container within the outer housing.

There is provided an aerosol generating system, the system comprising: aerosol generating means; aerosol delivery means; and an aerosol guiding device (1). The aerosol guiding device comprises a chamber having an air inlet (14) and an air outlet (12) and the aerosol delivery means is configured such that aerosol is introduced from the aerosol generating means into the chamber in use. An airflow route is defined from the air inlet to the air outlet so as to convey the aerosol to the air outlet, and the relative dimensions of the air inlet and the air outlet are selected to provide pressure control means for controlling the pressure differential between the air inlet and the air outlet. There is also provided an aerosol guiding device for use in an aerosol generating system, the device comprising: a chamber having an air inlet and an air outlet.
