Description

Aerosol generating device, and heating chamber for the same The present disclosure relates to an aerosol generating device and a heating chamber for the same. The present disclosure is particularly applicable to a portable aerosol generating device that is self-contained and may be low temperature. Such a device may generate an aerosol for inhalation by heating by conduction, convection, and/or radiation, instead of burning tobacco or other suitable material. Due to the use and popularity of risk reduction or risk modification devices (also known as vaporizers), aid devices to assist habitual smokers who wish to quit traditional tobacco products, such as cigarettes, cigars, cigarillos, and rolled tobacco, have grown rapidly over the past few years. In contrast to burning tobacco in conventional tobacco products, various devices and systems are available that heat or warm aerosolizable materials. A commonly available risk reduction or risk modification device is a heated substrate aerosol generator or a heat-not-burn device. This type of device generates an aerosol or vapor by heating an aerosol substrate, typically comprising wet leaf tobacco or other suitable aerosolizable material, to a temperature typically ranging from 150°C to 300°C. By heating the aerosol substrate without igniting or burning it, an aerosol is released that contains the desired components of the user but does not contain toxic and carcinogenic ignition and combustion byproducts. Additionally, since the aerosol generated by heating tobacco or other aerosolizable material does not typically contain a burnt or bitter taste resulting from ignition and combustion, which may be unpleasant to the user, the substrate does not require sugars and other additives typically added to such materials to make the smoke and/or vapor more palatable to the user. In general terms, it is desirable to rapidly heat the aerosol substrate and maintain it at a temperature from which the aerosol can be released. It will be obvious that the aerosol is released only from the aerosol substrate and is delivered to the user if there is an airflow passing through the aerosol substrate. Since this type of aerosol generator is a portable device, energy consumption is an important design consideration. The present invention aims to solve the problems of existing devices and to provide an improved aerosol generator and a heating chamber for the same.
