A cartridge for an aerosol-generating system includes a storage container containing a supply of an aerosol-forming substrate, a fluid permeable heating element positioned across an opening in the storage container, a protective cover coupled to the storage container and covering the fluid permeable heating element, at least one air inlet, at least one air outlet, and an airflow path from the at least one air inlet to the at least one air outlet. The protective cover is configured such that a portion of the airflow path is between the protective cover and the fluid permeable heating element.

A fluid permeable heater assembly for an aerosol-generating system includes a cap and a substantially flat electrically conductive and fluid permeable heating element. The cap includes a hollow body with a first cap opening and a second cap opening. The first cap opening is opposite to the second cap opening. The heating element is configured to vaporise aerosol-forming substrate. The heating element is mounted on the cap, such that the heating element extends across the first cap opening. A cartridge for an aerosol-generating system includes the heater assembly, a liquid storage portion, a mouth piece, and a retainer.

An electrically operated aerosol-generating system may be configured to detect adverse conditions (e.g., a dry heater). The system may comprise an electric heater comprising at least one heating element for heating an aerosol-forming substrate, a power supply, and electric circuitry connected to the electric heater and to the power supply and comprising a memory. The electric circuitry may be configured to measure an initial electrical resistance (R.sub.1) of the electric heater; measure a subsequent electrical resistance of the electric heater after the measurement of the initial electrical resistance; determine the difference (?R) between the initial electrical resistance and the subsequent electrical resistance; determine that an adverse condition is present if the difference is greater than a maximum threshold value (?R.sub.max) or less than a minimum threshold value (?R.sub.min) stored in the memory; and control a power to the electric heater and/or provide an indication if the adverse condition is present.

The present application is disclosed an atomizing component and an electronic cigarette. The atomizing component comprises a light-permeable e-liquid storage sleeve. An atomizing core is detachably connected to an end of the e-liquid storage sleeve. A fastening element for restricting radial expansion of the e-liquid storage sleeve is sleeved at where the e-liquid storage sleeve is insertedly connected to the atomizing core. An end of a ventilation pipe opposite to the atomizing core is a smoke emitting outlet in communication with a suction nozzle. An e-liquid filler hole is extended from the end of the ventilation pipe provided with the smoke emitting outlet. The smoke emitting outlet and the e-liquid filler hole are located on planes of different heights; while e-liquid is being added, the outer circumferential wall of the ventilation pipe blocks the e-liquid splashed accidentally, thus preventing the e-liquid from being splashed into the ventilation pipe.

An energy regulating system and thermally regulated article for a habitable space or vehicle interior space are provided which include a thermally conductive member, such as one or more sheets of flexible graphite member, in thermal communication with a thermal energy source such as a heat source or cold source. The thermally conductive -member having an exterior surface adapted to be exposed to an occupant of the vehicle or building. A controller is in operable communication with a power source connected in the heat source or cold source for regulating the temperature perceived by the occupant by varying the power supplied to the heat source or cold source.
