Description

Heating oven for an aerosol generating device configured to operate consumable items The present invention relates to the field of aerosol generating devices, particularly to a heating oven for an aerosol generating device configured to operate a consumable article. The consumable article comprises an aerosol substrate containing a vaporizable substance to form an aerosol when heated, for example, by a heating oven of an aerosol generating device. Thus, this type of aerosol generating device (also known as a "heat-not-burn device") is designed to generate an inhalable aerosol through heating instead of combustion. The popularity and use of low-risk or risk-mitigation devices (also known as vaporizers) have increased rapidly over the past few years and are being utilized as an aid to help habitual smokers quit traditional tobacco products such as cigarettes, cigars, cigarillos, and roll-your-own tobacco. Unlike the method of burning tobacco in conventional tobacco products, a variety of devices and systems are available that heat or warm vaporizable materials. Generally available low-risk or risk-mitigation devices include heated substrate aerosol generating devices or so-called "heated non-combustion devices." This type of aerosol generating device generates aerosols or vapors by heating an aerosol substrate contained in a consumable article separate from the aerosol generating device. Typically, such aerosol substrates contain moist leaf tobacco or other suitable vaporizable materials that evaporate at temperatures typically ranging from 150°C to 350°C. Heating the aerosol substrate without burning or combusting releases an aerosol containing the components desired by the user but without the byproducts of combustion and burning. Furthermore, the aerosol generated by heating the vaporizable material contained in the aerosol substrate does not contain the typical burnt or bitter taste resulting from combustion and burning that may be unpleasant to the user, nor does it contain smoke that may be irritating and polluting to the surrounding environment. Consumable articles usable with this type of aerosol generating device can take various shapes. Some of these may have an elongated rod shape or other suitable shapes, such as a plate shape, for example. Generally, these consumable articles are at least partially accommodated in the heating chamber of a heating oven of the aerosol generating device that heats the consumable articles, which includes one or more heaters. In some cases, heating of consumable items is not entirely efficient, which may cause users to experience difficulties when inhaling aerosols, and the user experience may be less pleasant, for example, by requiring longer inhalation to obtain the required amount of aerosol. The present invention and its advantages can be better understood by reading the following description, which is presented through non-limiting examples and refers to the accompanying drawings. - FIG. 1 is a schematic cross-sectional view of an aerosol generating assembly including an aerosol generating device and a consumable article; - FIG. 2 is a perspective view of the consumable item of FIG. 1; - FIG. 3 is a longitudinal section of the consumable item of FIG. 2; - FIG. 4 is a perspective view of a heating oven of an aerosol generating device; - FIG. 5 is a cross-sectional view of the heating oven of FIG. 4 along the VV line of FIG. 4; - FIG. 6 is a longitudinal section of the heating oven of FIG. 4 along the line VI-VI of FIG. 4; - FIG. 7 illustrates a longitudinal section view of the heating oven of FIG. 4 during the insertion of consumable items; - FIG. 8 illustrates a perspective view of another consumable item; - FIG. 9 illustrates a cross-sectional view of a heating oven containing the consumable items of FIG. 8. Before describing the present invention, it should be understood that the present invention is not limited to the structural details disclosed in the following description. It will be apparent to those skilled in the art who benefit from this disclosure that the present invention can be implemented in other embodiments and can be practiced or performed in various ways. As used herein, the terms “ aerosol generating device ” or “ device ” may include a vaping device that delivers an aerosol containing a vaping aerosol to a user via a heating oven, which is further described in detail below. The device may be portable. “Portable” may mean that the user can hold and use the device in their hand. The device may be configured to generate an aerosol by operating the heating oven for a variable time (unlike a metered-dose method), for example, and this may be controlled by a trigger. The trigger may be operated by the user, such as a vaping button. The device may include a temperature control function for raising the temperature of the heating oven and/or the heated vaporizable material (aerosol precursor) to a specified target temperature and then maintaining the
