Disclosed herein are aspects of portable vaporizers forming isolated vapor paths through vapor dispensers wherein a material chamber is part of a unitary furnace formed above a resistive heater and aliquots of heated air are drawn through plant-based material in the formed material chamber. A printed circuit board in signal communications with at least one temperature sensor controls the power flow to the resistance heater to select the temperature produced by heating elements in the furnace. A rechargeable battery power supply is mounted in a body to supply power the heating element.

A method of controlling an aerosol-generating device including a heater, the method including, over a period of more than 30 seconds, and independent of whether a user is puffing on the device or not: heating the heater to a first temperature, then heating the heater to a second temperature lower than the first temperature, and then heating the heater to a third temperature higher than the second temperature. There is also provided an aerosol-generating device including a heater and a controller; and there is also provided a system including the aerosol-generating device.

There is provided a method of compensating for changes to a solid aerosol-forming substrate during heating of the substrate by a heating element over a period containing a first plurality of user puffs and a second plurality of user puffs, the changes including warming of the substrate and depletion of the substrate, the method including: compensating for the warming of the substrate by reducing heating of the heating element during the first plurality of user puffs; and after compensating for the warming of the substrate, compensating for the depletion of the substrate by increasing heating of the heating element during the second plurality of user puffs. There is also provided a system for compensating for changes to a solid aerosol-forming substrate during heating of the substrate by a heating element over a period containing a first plurality of user puffs and a second plurality of user puffs.

A modular heated surface system which can quickly be assembled from several pieces. The system can be designed to fit sidewalks and driveways of any size and includes durable surfaces for driving vehicles across the platforms. A drain assembly is included to ensure that the water produced from melted ice and snow is properly drained away from the heated surface. The system is powered by plugging the system into a standard 120V outlet.

A disposable consumable with tobacco, hemp and/or cannabis therein is heated in a keyed receivor allowing conduction and convection. The consumable when inserted into a heating chamber via a keyed receivor will have one or more linear sections running axially that are in direct contact with the inner wall of the heating chamber and one or more linear sections that are remote from the inner wall with a volume of air between the cartridge and inner wall. Direct contact sections are heated via conduction through the heating chamber wall and the heated air volume forms a convection airflow for inhalation.

Efficient Heating of a consumable containing tobacco (or other plant material) without combustion using multiple induction heating zones for smoke free release of pant resins for use with tobacco or cannabis, including utilizing a removable cartridge which may contain metal foil regions. The cartridge is placed removably into a guide wherein heating occurs in zones via conductive and/or inductive heating elements. Such heat being at a sufficient temperature to vaporize resins or oils on plant material such as hemp, tobacco and cannabis, for inhalation from the cartridge.

Provided is an aerosol generating device which is capable of optimizing the timing at which aerosol generation is stopped. This aerosol generating device 100 includes: a power source 114 which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor 106 which outputs a measurement value indicating a first physical quantity for controlling the power supplied; and a controller 130 which acquires the measurement value output by the sensor 106, stores a profile of the measurement value, and controls the supplied power by controlling a second physical quantity different to the first physical quantity, on the basis of the acquired measurement value and at least a part of the stored profile of the measurement value.

Provided is an aerosol generating device which is capable of stopping aerosol generation at an appropriate timing. This aerosol generating device includes a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a circuitry which controls the power supplied from the power source on the basis of the measurement value. The circuitry controls to increase a power supply amount per unit time in response to a first condition that the measured value is equal to or larger than a first threshold being satisfied, and to decrease the power supply amount per unit time in response to a second condition that the measured value is less than a second threshold greater than the first threshold and a third condition which is different from the first condition and the second condition being satisfied.
