Referring to FIGS. 1(a) and 1(b), an example of an aerosol-generating article 10 is illustrated from a first side (angle) and a second side (angle). The aerosol generating article 10 is elongated and substantially cylindrical and of the so-called "stick" type. Aerosol generating article 10 has a distal (or upstream) end I and an oral (or downstream) end M. The aerosol-generating article is inserted into the aerosol-generating device 30 and configured to be consumed.

The aerosol generating article 10 is arranged in a downstream direction or direction opposite insertion, in other words from a distal end I to a proximal end M, sequentially and coaxially (in other words, with a central longitudinal axis shown as a dashed line in the figure, i.e. a cylindrical shape). The following elements are arranged in alignment (defined along the longitudinal axis defined at the center of the circular cross-section of the aerosol-generating article 10 and passing through the center of mass of the internal body itself): a self-sealing airflow; It includes an aerosol-generating substrate 16 along with a barrier 28, an inductively heatable susceptor 17, an optional vapor cooling element 18, and an optional filter 20 including, for example, cellulose acetate fibers. These elements are all assembled inside the wrapper 22 to form a rod, and the wrapper 22 holds the elements in place to form the aerosol-generating article 10.

Wrapper 22 is substantially electrically non-conductive and magnetically non-permeable and typically comprises a paper wrapper, such as a cigarette wrapper.

Aerosol-generating substrate 16 includes solid or semi-solid materials (ie, non-liquid materials) and may include plant-based materials, particularly tobacco. Aerosol generating substrate 16 typically includes a tobacco plug. Aerosol-generating substrate 16 may include an aerosol-forming agent, such as glycerin or propylene glycol, to facilitate vapor or aerosol generation when heated.

The inductively heatable susceptor 17 is positioned in close proximity to, in contact with, or in this embodiment contained within the aerosol-generating substrate 16 . The inductively heatable susceptor 17 functioning as a heater may include a blade-shaped susceptor coextensive with the sidewalls of the cavity 38.

FIG. 1(a) shows a cross-sectional view of the aerosol-generating article 10 from a first side (angle), and FIG. Figure 2 shows a cross-sectional view of the aerosol-generating article 10 from a second side (angle) that is viewed vertically.

The induction heatable susceptor 17 is centrally located and coextensive with (and preferably shares a centerline with) the central longitudinal axis of the article 10 . As shown in FIG. 1(b), when viewed from a second angle, aerosol generating article 10 and susceptor 17 are configured to be symmetrical about a central longitudinal axis.

Aerosol generating article 10 has an air inlet 24 at a distal end I and an air outlet 26 at a mouth end M. A self-sealing airflow barrier 28 is disposed at the distal end I of the aerosol-generating article 10. The self-sealing air flow barrier 28 may be a resilient wall and may be a septum self-sealing material, typically an elastomeric material such as silicone rubber or cork or the same material often found in gas chromatography vials and medical applications. Contains other materials with properties. A portion of the self-sealing airflow barrier 28 is secured to the wrapper 22 around its periphery, and another portion 28a thereof is secured to the wrapper 22 in an upstream position relative to the remainder of the self-sealing airflow barrier 28. protrude from In other words, portion 28a projects from distal end I of article 10. Self-sealing air flow barrier 28 prevents air flow from air inlet 24 to air outlet 26 through aerosol-generating substrate 16, thereby reducing the tendency for ignition and/or sustained combustion of aerosol-generating substrate 16. reduce

Regarding the arrangement and position of the inductively heatable susceptor 17, the other part 28a has a profile that has the effect that the article 10 can be inserted into the aerosol-generating device 30 preferably only in one or in this embodiment two different orientations; Preferably, it is configured to have a prismatic or cylindrical shape. As shown in FIGS. 1(a) and 1(b), the protruding orientation element 28a has a rectangular parallelepiped shape with a length 29a on a first side and a width 29b on a second side. Length 29a is longer than width 29b. In other embodiments, article 10 may be placed within device 30 in more than two orientations. This arrangement allows the user to easily orient the aerosol-generating article 10 correctly by his or her sense of touch by rotating the article 10 within the cavity 38 of the aerosol-generating device 30 along its central longitudinal axis. .

The puncture surface of the self-sealing air flow barrier 28 that is destroyed during insertion is located on the protruding directing element 28a or the remaining portion of the self-sealing air flow barrier 28. The puncture surface of the self-sealing air flow barrier 28 preferably has a locally reduced thickness to facilitate puncture or perforation by the puncture element 52 described below. For example, the wall may include a pre-weakened area within the area that is to be punctured or perforated. The pre-weakened area can be formed as a small circle or can be transversely linear or cross-shaped. Self-sealing air flow barrier 28 can be made of a flame resistant material such as silicone or cork. In a possible embodiment, the self-sealing airflow barrier 28 is a pre-scorched or pre-scorched elastic wall that is closed in a relaxed state and forced open by the insertion element 52. If the self-sealing airflow barrier 28 has one or more slits, the self-sealing airflow barrier 28 may be too resistant to inhalation and may cause the user's inhalation at the mouth end M of the aerosol-generating article 10 to be difficult. Cannot be opened by suction.

Steam cooling element 18 typically includes a hollow paper tube 18a having a thickness that exceeds the thickness of paper wrapper 22. As the heated vapor flows downstream through the vapor cooling element 18 from the aerosol-generating substrate 16 toward the mouth end M, the vapor cools and condenses to form an aerosol with properties suitable for inhalation by a user. Form. The vapor cooling element 18 (e.g., hollow paper tube 18a) may contact the aerosol-generating substrate 16 at the first end, as shown in FIGS. 1(a) and 1(b), but other implementations are possible. The configuration may be spaced apart from the aerosol generating substrate 16.

Referring now to FIG. 2, an aerosol generation system 1 is schematically illustrated. Aerosol generation system 1 includes an electric aerosol generation device 30 and the aerosol generation article 10 described above.

Aerosol generation device 30 has a first (or proximal) end 32 and a second (or distal) end 34 and includes a device housing 36. Aerosol generation device 30 further includes a cavity (i.e., heating chamber) 38 having a substantially cylindrical cross-section, a power source 40, such as one or more batteries, and a controller 42, all within device housing 36. will be placed in Aerosol generation device 30 is a handheld portable elongated device, meaning that the user can hold and support the device with one hand without assistance.

The cavity 38 has a proximal (open) end 44 and a distal (bottom) end 46 that correspond separately from a distal end I to a proximal end M. The cavity includes an opening 48 at the proximal end 44 and a hollow section 51 at the distal end 46 . The hollow portion in the bottom surface of the cavity 38 is configured to have a concave shape corresponding to the contour of the protruding directing element 28a, and is configured to orient and/or guide the aerosol-generating article in a corresponding direction with respect to the directing means 28a. Functions as a means of attachment. In other words, when the protruding orientation element 28a fits within the hollow portion 51, the article 10 is placed within the cavity 38 of the device 30 in the desired and predetermined orientation. In the illustrated embodiment, the article can be consumed when the protruding orientation element 28a is completely accommodated in the hollow portion 51.

Cavity 38 includes a substantially cylindrical sidewall 50, ie, a sidewall 50 having a substantially circular cross section. Aerosol generating article 10 is placed within cavity 38 by inserting distal end I into cavity 38 through opening 48 along the insertion direction. For maximum accommodation within the cavity 38 and maximum insertion of the protruding orientation element 28a into the hollow portion 51, the article 10 is rotated about its central longitudinal axis to orient the article 10. Can be adjusted. The hollow portion 51 and the protruding directing element 28a are dimensioned such that the hollow portion 51 can suitably fit and accommodate only the protruding directing element 28a. Cavity 38 and aerosol-generating article 10 are arranged such that when article 10 is maximally contained within cavity 38 of device 30 , the oral end M, particularly filter 20 , exits cavity 38 at first (proximal) end 44 . It is dimensioned to protrude and allow engagement by the user's lips.

The aerosol generating device 30 includes an insertion element (penetration) 52, in the example shown, a hollow puncture disposed at the distal end 46 of the cavity 38 and projecting into the cavity 38 from the distal end 46 towards the proximal end 44. Contains element 52. Hollow piercing element 52 has a frustoconical outer surface 54 and may include a one-way valve, such as a duckbill valve. When the aerosol-generating article 10 is fully inserted into the cavity 38 as shown in FIG. to allow air to flow from the air outlet 26 to the air outlet 26.

In this embodiment, the insertion element 52 and the resilient walls of the self-sealing airflow barrier 28 are such that when the orientation element 28a is fully inserted into the hollow part 51, in other words the article 10 is inserted into the cavity 38 of the device 30. The insert element 52 is sized such that it is only when fully accommodated that the insertion element 52 can pierce the elastic wall of the self-sealing air flow barrier 28 and the user can begin consuming the article 10. be done. In other words, the insertion element 52 is inserted from the bottom (end) of the hollow part 51 substantially the same as, or preferably slightly larger than, the thickness of the elastic wall of the self-sealing airflow barrier 28. 52, i.e., having a dimension (height) in the direction opposite to insertion. In other words, the corresponding orientation means 28a are at most 10 mm, preferably at most 7 mm, more preferably at most 5 mm, even more preferably at most 3 mm, and most preferably at most about 1 mm in the direction of insertion of the article 10. and a length of at least 0.1 mm, preferably at least 0.3 mm, more preferably at least 0.5 mm, and most preferably at least about 0.7 mm. This arrangement allows the user to consume the article 10 only when the article 10 is placed in a predetermined orientation.

When aerosol generating article 10 is removed from cavity 38 , self-sealing airflow barrier 28 resumes its original shape, thereby filling the small opening created in airflow barrier 28 by hollow piercing element 52 . Seal. Thus, the self-sealing air flow barrier 28 again prevents air flow from the air inlet 24 to the air outlet 26 of the aerosol-generating article 10, reducing the tendency for ignition and/or sustained combustion of the aerosol-generating substrate 16. do.

The aerosol generation device 60 includes a magnetic field generator 62, preferably an induction heating coil, which functions as an exciter, corresponding to a susceptor within the aerosol generation article, to generate an electromagnetic field. Magnetic field generator 62 includes a flat induction heating coil 64 in the illustrated embodiment. A flat induction heating coil 64 is placed in position proximal to cavity 38 . Induction coil 64 can be energized by power source 40 and controller 42 . Controller 42 includes, among other electronic components, an inverter configured to convert direct current from power supply 40 to alternating high frequency current for induction coil 64 . Preferably, the exciter is arranged separately from the corresponding directing means (28a) within the aerosol generation device (30) as shown.

As will be appreciated by those skilled in the art, when the induction coil 64 is energized during use of the aerosol generation system 2, an alternating current, time-varying electromagnetic field is generated. This electromagnetic field couples with the inductively heatable susceptor and generates eddy currents and/or magnetic hysteresis losses in the susceptor, causing it to heat up. Heat is then transferred from the inductively heatable susceptor to the aerosol-generating substrate 16 by conduction, radiation, and convection, for example, to heat the aerosol-generating substrate 16 without combusting it, thereby producing steam. The airflow through the aerosol generation device 60 and thus through the aerosol generation article 10 is the same as described above with respect to the aerosol generation system 1 of FIG.

During operation of aerosol generation device 30, electrical energy is supplied to heater 62, preferably induction heating coil 64, by power supply 40 and controller 42. Power is transferred from the heater 62 to the aerosol-generating substrate 16 , preferably a susceptor 17 of the aerosol-generating substrate 16 of the aerosol-generating article 10 , by conduction, radiation and convection, preferably by the susceptor 17 . is heated without combustion, thereby producing steam. In other exemplary embodiments, the device 1 is oriented such that the article can be guided into a position aligned with and/or substantially close to the heater of the device 1 to have better heating performance. Any other type of heater may be arranged within the device 1, such as a resistance heater, but not limited to heating coils and susceptors, as may include means. When a user inhales (ie, inhales) at the mouth end M of the aerosol-generating article 10 , air is drawn into the aerosol-generating article 10 through the air passageway 56 within the device housing 36 . Air flows through the hollow piercing element 52 and the air inlet 24 of the aerosol generating article 10. Air then flows through the aerosol-generating substrate 16 such that the vapor generated by heating the aerosol-generating substrate 16 is entrained in the airflow and exits from the air outlet 28 at the mouth end M of the aerosol-generating article 10. carried towards. As the vapor flows through the vapor cooling element 18, it is cooled and condensed to form an aerosol. The aerosol then passes through filter 20 and is inhaled by the user.

In order to have a better (maximum) heating efficiency, the blade-shaped susceptor 17 should be placed parallel to the flat induction heating coil 64, i.e. in proper alignment with it. As shown in FIG. 2, when the article 10 is fully accommodated within the cavity 38, the second side (angle) faces the flat induction heating coil 64. In this embodiment, the orientation element 28a is a symmetrical rectangular parallelepiped, and the susceptor 17 and the coil 64 are flat, so that the article 10 can be moved between the second orientation and the opposite orientation. It can be placed within cavity 38 in one orientation. In both orientations, the substrate of the article 10 can be heated more effectively when facing the flat induction heating coil 64 than in any other orientation, such as the first orientation. This arrangement allows the user to more easily rotate the article 10 to the desired orientation since the user only needs to rotate the article half a cycle.

3(a), 3(b) and 3(c) show the substrate, blade-shaped susceptor 17 when the aerosol-generating article 10 is accommodated to the maximum within the cavity 38 of the aerosol-generating device 30. FIG. 3 is a partial illustration showing the distal end I of the aerosol-generating article 10 having a self-sealing airflow barrier 28 and the flat induction heating coil 64 of the aerosol-generating device 30. FIG. As mentioned above, in order to place the flat blade-shaped susceptor 17 parallel to the flat induction heating coil 64, the orientation element 28a inserts the article 10 into the cavity 38 of the device 30 in only two orientations. It is configured to have a cylindrical shape with a cross section that allows for. More specifically, the orientation element 28a has the shape of a polyhedron, preferably a cube, an irregular cylinder or a polygonal prism. In other embodiments, the susceptor 17 and coil 64 can have other shapes, such as a curved blade shape, as shown in FIG. 3(c). In these cases, the orientation element 28a, in this embodiment, directs the article into the cavity 38 so that the susceptor 17 can be placed in close proximity to and precisely aligned with the induction heating coil 64. It should have the shape of a column with a triangular cross section so that it can only be accommodated in one orientation.
