The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. For example, some aerosol delivery devices of the current disclosure include a reservoir having a liquid aerosol precursor composition, an electrical heater in fluid communication with the reservoir and configured to vaporize the liquid aerosol precursor composition to form an aerosol, and a filter operatively arranged relative to the electrical heater such that at least a portion of the formed aerosol passes therethrough, the filter being configured to selectively bind one or more undesirable impurities.

The present disclosure relates to aerosol delivery devices. The aerosol delivery devices may include a control body, an atomizer body including an atomizer, and a cartridge including a reservoir configured to contain an aerosol precursor composition. The control body may be configured to releasably engage the atomizer body and the atomizer body may be configured to releasably engage the cartridge. The atomizer may be configured to receive an electrical current from the control body and the aerosol precursor composition from the cartridge to produce an aerosol.

There is provided an aerosol-generating article (10) comprising an aerosol-generating substrate (12) and a mouthpiece (14) secured to a downstream end of the aerosol-generating substrate (12). The mouthpiece (14) comprises at least one segment of filter material (20) and a vented segment (27) downstream of the at least one segment of filter material (20) and comprising at least one freshener delivery element (26). The vented segment (27) comprising the at least one freshener delivery element (26) is detachable from the at least one segment of filter material (20) to decrease the ventilation of the aerosol-generating article (10).

An electronic cigarette includes an atomizer having a coil-less heating element having a heating section, two leads electrically connected to the heating section, and a liquid guiding structure. The liquid guiding structure includes two pads, a first pad and a second pad sandwiching at least a portion of the heating section. A gasket may be placed between a liquid supply and the first pad such that liquid is conducted from the liquid supply to the first pad.

A heater assembly for an aerosol-generating system includes a perforated glass substrate and a heater element. The heater element is encapsulated in the glass substrate. The heater element includes a thin metal foil. The heater element is isolated from an adjacent aerosol-forming substrate. The perforations have a width ranging from about 1 micron to about 500 microns.

On-demand, hand-held vaporizer that operates primarily by convection. The vaporizer is configured to permit very rapid heating of air drawn through an oven chamber to a predetermined or selectable vaporizing temperature to vaporize a material that is held in the oven chamber. The vaporizer provides efficient transfer of air being heated as well as rapid delivery of vaporizable material to a user.

A method of controlling an electric heater in an electrically heated smoking system is provided, including providing electrical power to the heater in pulses such that during active periods power is supplied to the heater and during inactive periods power is not supplied to the heater; charging a capacitor in an RC circuit during the inactive periods and allowing the capacitor to discharge during the active periods; and monitoring a discharge voltage of the capacitor and if the discharge voltage of the capacitor drops below a threshold voltage level, then stopping further supply of electrical power to the heater.

A novel device for vaporizing of phyto material is disclosed. The device includes a housing and a heating chamber, wherein the heating chamber is for receiving of phyto material, in first and second phyto material portions. The heating chamber includes a centrally located first heater element disposed on a first substrate and a second heater element disposed on the first substrate, the heater elements for outwardly radiating heat through the phyto material, where at least one of the heating elements is enabled and a user inhales vapor from an inhalation aperture in fluid communication with the heating chamber. An airflow processing member restricts a flow of ambient air into the heating chamber. The first heater element is for heating the first phyto material portion and the second heater element is for heating of the second phyto material portion.

The present disclosure relates to aerosol delivery devices, methods of forming such devices, and elements of such devices. In some embodiments, the present disclosure provides substrates for use in storing an aerosol precursor liquid and/or transporting the liquid to a heater for vaporization. The substrates can be formed form fibers that can provide improved absorbency and/or transport qualities. Multi-layer substrates are also disclosed and can include a high absorbency layer and a hydrophobic layer.

A method of charging a second battery in an electronic smoking device from a first battery in a charging device is provided, including: comparing an output voltage of the first battery with a threshold voltage; and when the output voltage is equal to or greater than the threshold voltage, charging the second battery using a first current; and when the output voltage is less than the threshold voltage, reducing the first current until the output voltage is equal to or greater than a second threshold voltage. A charging device is also provided, including control circuitry configured to control charging of the secondary battery.
