Provided is an aerosol generating device distributing and transmitting power from a battery to two heaters, wherein the aerosol generating device includes the battery, a first heater heating a first aerosol generating substrate, a second heater heating a second aerosol generating substrate, and a controller controlling power supplied from the battery to the first heater and the second heater, wherein the controller controls power to be supplied from the battery to the first heater and the second heater at different times.

An aerosol generating device defines a flow path from an air inlet to an inhalable medium outlet. The device includes a container for containing a liquid; a wick for drawing liquid from the container into the flow path, and a heating element, upstream of the wick, for heating inlet air from the air inlet to generate a flow of heated air in the flow path in use. The device is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilize the liquid to generate, in use, a flow of aerosol in the flow path. The device includes a receiving portion in the flow path, downstream of the wick, for receiving an element for modifying a property of the flow of aerosol. A device including a shield element to shield the wick from a heating element is also disclosed.

A method of controlling electric power supplied to a heater includes controlling the electric power supplied to the heater by a first method until a temperature of the heater reaches an upper limit of a pre-heating temperature section; and controlling the electric power supplied to the heater by a second method to a target temperature that is higher than the upper limit, when the temperature of the heater reaches the upper limit.

The present specification relates to heater element, device provided therewith and method for manufacturing such heater element. The heater element comprises a heater of a resistance heating metal that is provided in, at or close to a fluid path configured for heating fluid, wherein the heater comprises a conductor that is provided with a porous ceramic layer. In embodiments, the ceramic layer is provided on or at the conductor with plasma electrolytic oxidation. The ceramic layer has a thickness in the range of 5-300 μm.

On-demand, hand-held vaporizer that operates primarily by convection. The vaporizer is configured to permit very rapid (e.g., within a few seconds) heating of air drawn through an oven chamber to a predetermined or selectable vaporizing temperature to vaporize a material (e.g., loose leaf plant material, etc.) 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 heating element module for an aerosol-generating device is provided, including an elongate heating element having a heating portion; a heating element mount, wherein the heating element extends substantially perpendicularly from a first surface of the heating element mount; and first and second projections extending substantially perpendicularly from the first surface of the heating element mount and abutting first and second sides of the heating element. An aerosol-generating device incorporating the heating element module is also provided.

A heater assembly for an aerosol-generating system includes a perforated glass substrate and a heater element. The heater element is provided in the glass substrate, on the glass substrate, or both in and on the glass substrate. The heater element includes a plurality of parallel strips between alternating rows of the perforations.
