Definitions
- the present invention concerns an aerosol generating device comprising a heating chamber configured to receive at least partially an aerosol generating article.
- the aerosol generating device is configured to operate with an aerosol generating article, for example a flat-shaped tobacco article, which comprises for example a solid substrate able to form aerosol when being heated.
- an aerosol generating article for example a flat-shaped tobacco article, which comprises for example a solid substrate able to form aerosol when being heated.
- aerosol generating devices also known as heat-not-burn devices, is adapted to heat, rather than burn, the substrate by conduction, convection and/or radiation, to generate aerosol for inhalation.
- reduced-risk or modified-risk devices also known as vaporisers
- vaporisers have grown rapidly in the past few years as an aid to assist habitual smokers wishing to quit smoking traditional tobacco products such as cigarettes, cigars, cigarillos, and rolling tobacco.
- Various devices and systems are available that heat or warm vaporizable substances as opposed to burning tobacco in conventional tobacco products.
- a commonly available reduced-risk or modified-risk device is the heated substrate aerosol generation device or heat-not-burn device.
- Devices of this type generate aerosol or vapour by heating an aerosol substrate that typically comprises moist leaf tobacco or other suitable vaporizable material to a temperature typically in the range 150°C to 350°C. Heating an aerosol substrate, but not combusting or burning it, releases aerosol that comprises the components sought by the user but not the toxic and carcinogenic byproducts of combustion and burning.
- the aerosol produced by heating the tobacco or other vaporizable material does not typically comprise the burnt or bitter taste resulting from combustion and burning that can be unpleasant for the user and so the substrate does not therefore require the sugars and other additives that are typically added to such materials to make the smoke and/or vapour more palatable for the user.
- Tobacco articles usable with such type of aerosol generating devices can take various forms. Some of them can present an elongated stick or any other suitable shape, like for example a flat shape. Generally, such a tobacco article is received at least partially in a heating chamber of the device which comprises one or several heaters to heat the tobacco article.
- Heating efficiency by the heating chamber is thus an important operation parameter of the aerosol generating device.
- heat generated by the heating chamber can be dissipated. This can cause not only under-heating of the tobacco article and as a consequence a poor vapour generation, but in some cases also over-heating of the device body and notably of a zone of the device body used to handle the device by the user. This can conduct to a poor user experience.
- One of the aims of the invention is to propose an aerosol generating device providing a better heating efficiency of an aerosol generating article and as a consequence, a better user experience.
- the quality of vapour generation can be increased while reducing the device body over-heating.
- the invention relates to an aerosol generating device comprising a device body and a heating chamber configured to receive at least partially an aerosol generating article;
- the heating chamber is attached to the device body only in the mounting zone.
- the mounting zone forms the only heat transfer zone between the heating chamber and the device body. Heat transfer can thus be minimized by optimizing the structure of the mounting zone.
- the mounting zone can be configured to be engaged with the support of the device body using optimized means. These means can be optimized to minimize heat transfer between the heating chamber and the device body.
- the means attaching the heating chamber to the device body can be configured to be easily disengaged by the user.
- the heating chamber can be detached from the device body to be for example cleaned or replaced by the user.
- the heating chamber is adapted to receive an aerosol generating article having a flat shape.
- the flat shape of the heating chamber is particularly advantageous to ensure a fast preheating phase of the aerosol generating article.
- the article can be ready to generate vapor only a few seconds (for example 5 s or 15 s or 20 s) after activating the heating chamber.
- the flat shape of the heating chamber is also advantageous to ensure a relatively great amount of vapor and homogeneous heating of the aerosol generating article during a vaping phase.
- the or each protruding part extends according to the central plane to reduce the size of the device body and keep it also substantially flat.
- the flat shape of the heating chamber can extend according to the central plane.
- the or each protruding part extends according to this plane without breaking the flat shape of the device body receiving the heating chamber.
- the device body can be only slightly thicker than the heating chamber.
- the distance between the mounting zone and the heating zone of the heating chamber can be maximized, minimizing thus heat transfer from the heating zone to the mounting zone.
- the heating chamber can be seen as a floating structure inside the device body which is attached to this body only at one of its ends.
- the mounting zone is engaged with the support by means of two protruding parts
- the heating chamber can be solidary attached to the support.
- the mounting zone is engaged with the support by means of only two protruding parts engaged with two respective pins.
