The present disclosure relates to an aerosol-generating article, an aerosol-generating device for the aerosol-generating article, and an aerosol-generating system which is a combination of an aerosol-generating article and an aerosol-generating device.

The use and popularity of risk-reducing or risk-modifying devices (also known as aerosol-generating devices or vapor-generating devices) as alternatives to the use of traditional tobacco products has grown rapidly in recent years. A variety of different devices, articles and systems are available for heating or elevating an aerosol-generating substance to generate an aerosol for inhalation by a user.

Commonly used risk reduction or risk modification devices are heated matrix aerosol generating devices or so-called heat-not-burn devices. This type of device generates an aerosol or vapor by heating an aerosol-generating substrate to a temperature typically in the range of 150°C to 300°C. Heating the aerosol-generating substrate to a temperature within this range without burning or burning the aerosol-generating substrate generates a vapor that typically cools and condenses to form an aerosol that is inhaled by the user of the device.

Currently available aerosol-generating devices can use one of a number of different methods to provide heat to the aerosol-generating substrate (including resistive heating and inductive heating). Regardless of which route is used to heat the aerosol-generating substrate, it may be convenient to provide the aerosol-generating substrate in the form of an aerosol-generating article configured for use with an aerosol-generating device. Aerosol-generating articles are known in the art and typically comprise an aerosol-generating substrate at the distal end of the aerosol-generating article and a filter at the proximal (mouthpiece) end.

The preferred embodiment will now be described, by way of example only, with reference to the accompanying drawings.

Referring to Figures 1(a) and 1(b), there is schematically shown an example of an aerosol-generating article 10 seen from a first aspect (angle) and a second aspect (angle). The aerosol-generating article 10 is elongated and generally cylindrical, and is also referred to as a "stick" type. The aerosol-generating article 10 has a distal (or upstream) end I and a mouthpiece (or downstream) end M. The aerosol-generating article is configured to be inserted into and consumed within the aerosol-generating device 30 .

The aerosol-generating article 10 comprises the following in the downstream or anti-insertion direction (in other words, from the distal end I to the mouthpiece end M) sequentially and coaxially (in other words, arranged along the longitudinal central axis, i.e. along the At the center of the circular section of the sol-generating article 10 and internally through the longitudinal axis of the center of mass of the body itself, as indicated by dotted lines in the figure) aligned elements: self-sealing airflow barrier 28, aerosol-generating substrate 16 Along with an inductively heatable susceptor 17, an optional vapor cooling element 18, and an optional filter 20 (eg, comprising cellulose acetate fibers). The elements are all assembled within the wrapper 22 to form the rod, and the wrapper 22 holds the elements in place to form the aerosol-generating article 10 .

Wrap 22 is substantially electrically and magnetically impermeable and typically comprises a paper wrap, such as cigarette paper.

Aerosol-generating substrate 16 includes solid or semi-solid material (ie, non-liquid material), and may include plant-derived material, especially tobacco. The aerosol-generating substrate 16 typically comprises 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 proximate to, in contact with, or in this embodiment contained within the aerosol-generating substrate 16 . The inductively heatable susceptor 17 (acting as a heater) may comprise a blade-shaped susceptor coextensive with the side walls of the cavity 38 .

Figure 1(a) shows a cross-sectional view of an aerosol-generating article 10 obtained from a first aspect (angle); Figure 1(b) shows a cross-section of an aerosol-generating article 10 obtained from a second aspect (angle) View, the second aspect is an angle perpendicular to the first angle, in other words, viewed perpendicular to the first aspect.

The inductively heatable susceptor 17 is arranged at a central location and is coextensive (preferably with a common center line) with the longitudinal center axis of the article 10 . As shown in Figure 1(b), the aerosol-generating article 10 and susceptor 17 are arranged symmetrically about the longitudinal central axis when viewed from a second angle.

The aerosol-generating article 10 has an air inlet 24 at the distal end I and an air outlet 26 at the mouthpiece end M. A self-sealing airflow barrier 28 is positioned at the distal end I of the aerosol-generating article 10 . The self-sealing gas flow barrier 28 may be an elastic wall and comprise a septum self-sealing material, typically an elastomeric material such as silicone rubber or cork or other materials of the same nature commonly found in gas chromatography vials and medical applications. A portion of the periphery of the self-sealing airflow barrier is fixed to the wrap 22 , while another portion 28a thereof protrudes from the wrap 22 at an upstream position relative to the remainder of the self-sealing airflow barrier 28 . In other words, it protrudes from the distal end I of the article 10 . Self-sealing airflow barrier 28 prevents airflow from air inlet 24 through aerosol-generating substrate 16 to air outlet 26, and this reduces the tendency of aerosol-generating substrate 16 to ignite and/or sustain combustion.

With respect to the arrangement and position of the inductively heatable susceptor 17, the further portion 28a is configured to have an outer shape, preferably a prism or a cylindrical shape, so that the article 10 can only be preferably one, or in this embodiment Insert the aerosol-generating device 30 in two different orientations in one manner. As shown in Figures 1(a) and 1(b), the protruding orientation element 28a has a cuboid shape with a length 29a in a first aspect and a width 29b in a second aspect. Length 29a is greater than width 29b. In other embodiments, article 10 may be arranged in device 30 in more than two orientations.

The perforated surface of self-sealing airflow barrier 28 preferably has a locally reduced thickness to facilitate perforation or piercing by perforating element 52 (discussed below). For example, the wall may comprise a pre-weakened zone in the area intended to be perforated or pierced. The pre-weakened zone may be shaped in the transverse direction as a small circle, or may be linear or cross-shaped. Self-sealing airflow barrier 28 may be made of a flame resistant material such as silicone or cork. In a possible mode, the self-sealing air flow barrier 28 is a pre-cut or pre-scored elastic wall which is closed in a relaxed state and forced open by the insertion element 52 . When the self-sealing airflow barrier 28 has one or more slits, the self-sealing airflow barrier 28 cannot be opened by the user's suction at the mouth end M of the aerosol-generating article 10 because the suction resistance is too great.

Vapor cooling element 18 typically includes a hollow paper tube 18 a having a thickness greater than that of paper wrap 22 . As the heated vapor flows in a downstream direction from the aerosol-generating substrate 16 towards the mouthpiece end M through the vapor cooling element 18, the vapor cools and condenses to form an aerosol having properties suitable for inhalation by the user. Vapor cooling element 18 (e.g., hollow paper tube 18a) may contact the first end of aerosol-generating substrate 16, as shown in FIGS. Substrates 16 are spaced apart.

Referring now to Figure 2, an aerosol generating system 1 is shown diagrammatically. The aerosol generating system 1 comprises an electrically operated aerosol generating device 30 and an aerosol generating article 10 as described above.

The aerosol-generating device 30 has a first (or proximal) end 32 and a second (or distal) end 34 and includes a device housing 36 . The aerosol-generating device 30 further includes: a cavity (i.e., a heating chamber) 38 having a generally cylindrical cross-section; a power source 40, such as one or more batteries; and a controller 42, all located in the device housing 36. middle. The aerosol-generating device 30 is a hand-held portable elongated device, which means that the user can hold and support the device with one hand.

The cavity 38 has a proximal (open) end 44 and a distal (bottom) end 46 corresponding to the distal end I and the mouthpiece end M, respectively. The cavity includes an opening 48 at the proximal end 44 and a hollow 51 at the distal end 46 . The hollow portion (located at the bottom surface of the cavity 38) is configured to have a concave shape corresponding to the outer shape of the protruding orientation element 28a, to indicate and/or guide the orientation of the aerosol generating article and to serve as an orientation device 28a. paired orientation devices. In other words, when the protruding orientation element 28a fits into the hollow portion 51, the article 10 is positioned in the cavity 38 of the device 30 in a desired and predetermined orientation. In the illustrated embodiment, the article may be consumed when the protruding orientation element 28a is fully received within the hollow portion 51 .

The cavity 38 includes a generally cylindrical side wall 50 , ie a side wall 50 having a generally circular cross-section. The aerosol-generating article 10 is positioned in the cavity 38 by inserting the distal end 1 into the cavity 38 through the opening 48 along the insertion direction. For maximum containment within cavity 38 , article 10 may be rotated about the central longitudinal axis to adjust the orientation of article 10 to maximize insertion of protruding orientation element 28a into hollow portion 51 . The hollow portion 51 and the protruding orientation element 28a are dimensioned such that the hollow portion 51 can fit and accommodate only the protruding orientation element 28a. The cavity 38 and the aerosol-generating article 10 are dimensioned such that the mouthpiece end 24, and in particular the filter 20, protrude from the first (proximal) end 44 of the cavity 38 to allow the article 10 to be maximally contained within the device 30. Engages the user's lips while in the cavity 38 of the lip.

The aerosol-generating device 30 comprises an insertion element (piercing portion) 52, in the example shown a hollow perforating element 52, which is arranged at the distal end 46 of the cavity 38 and protrudes into the cavity from the distal end 46 towards the proximal end 44. cavity 38. The hollow perforated element 52 has a frusto-conical outer surface 54 and may comprise 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. 2, the hollow perforated element 52 perforates the self-sealing airflow barrier 28, thereby allowing air to flow from the air inlet 24 through the aerosol-generating article 10 to the air outlet. 26.

In this embodiment, the insertion element 52, and the elastic walls of the self-sealing airflow barrier 28, are dimensioned such that only when the orientation element 28a is fully inserted into the hollow portion 51, in other words, the product 10 is maximally accommodated in the device. When in the cavity 38 of the airflow barrier 30, the insertion element 52 can perforate the elastic wall of the self-sealing airflow barrier 28 so that the user can begin to consume the article 10. In other words, the insertion element 52 is configured to have a dimension (height) that is substantially equal to or preferably slightly Greater than the thickness of the elastic wall of the self-sealing airflow barrier 28 . In other words, the mating orientation means 28a has a length in the direction of insertion of the article 10, i.e. 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; and 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. With this arrangement, a user can only consume article 10 when article 10 is positioned in a predetermined orientation.

When the aerosol-generating article 10 is removed from the cavity 38 , the self-sealing airflow barrier 28 returns to its original shape, thereby sealing the small opening in the airflow barrier 28 created by the hollow perforated element 52 . Thus, self-sealing airflow barrier 28 again prevents airflow from air inlet 24 to air outlet 26 of aerosol-generating article 10, thereby reducing the tendency of aerosol-generating substrate 16 to ignite and/or sustain combustion.

The aerosol-generating device 60 includes a magnetic field generator 62 for generating an electromagnetic field, which acts as an actuator, preferably an induction heating coil, corresponding to a susceptor in the aerosol-generating article. In the illustrated embodiment, the magnetic field generator 62 includes a flat induction heating coil 64 . The flat induction heating coil 64 is arranged at a predetermined position near the cavity 38 . The induction coil 64 may be energized by the power supply 40 and the controller 42 . The controller 42 includes, among other electronic components, an inverter arranged to convert the direct current from the power supply 40 into an alternating high-frequency current for the induction coil 64 . The actuator is preferably arranged in the aerosol generating device (30) separately from the mating orientation device (28a), as shown.

Those skilled in the art will understand that when the induction coil 64 is energized during use of the aerosol generating system 2, an alternating and time-varying electromagnetic field is generated. This electromagnetic field couples to the inductively heatable susceptor and induces eddy currents and/or 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, such as by conduction, radiation, and convection, to heat without burning the aerosol-generating substrate 16 and thereby generate vapor. The airflow passes through the aerosol-generating device 60, and thus through the aerosol-generating article 10, as described above in connection with the aerosol-generating system 1 of FIG.

During operation of the aerosol-generating device 30 , electrical power is supplied by the power supply 40 and the controller 42 to the heater 62 , preferably an induction heating coil 64 . Electricity is transferred from heater 62 to aerosol-generating substrate 16 of aerosol-generating article 10, preferably susceptor 17 of aerosol-generating substrate 16, such as by conduction, radiation, and convection, such that aerosol-generating substrate 16 preferably It is by the susceptor 17 that heats up without burning and thus generates steam. In other exemplary embodiments, any other type of heater, not limited to heating coils and susceptors, such as a resistive heater, can be arranged in the device 1 in such a way that the device 1 can include orientation means so that the article can be directed to a location aligned with and/or in significant proximity to the heater of the device 1 for better heating performance. When a user draws (ie draws on) the mouthpiece end M of the aerosol-generating article 10 , air is drawn through the aerosol-generating article 10 via the airflow passage 56 in the device housing 36 . Air flows through the hollow perforated element 52 and the air inlet 24 of the aerosol-generating article 10 . The air then flows through the aerosol-generating substrate 16, and thus the vapor generated by heating the aerosol-generating substrate 16 is entrained in the airflow and conveyed towards the air outlet 28 at the mouth end M of the aerosol-generating article 10. The vapor cools and condenses as it passes through the vapor cooling element 18 to form an aerosol. The aerosol then passes through the filter 20 and is inhaled by the user.

For better (maximum) heating efficiency, the blade-shaped susceptor 17 should be positioned parallel to (ie, properly aligned with) the flat induction heating coil 64 . As shown in FIG. 2 , the second aspect (angle) faces the flat induction heating coil 64 when the article 10 is maximally contained in the cavity 38 . In this embodiment, since the orientation element 28a is a symmetrical cuboid, and the susceptor 17 and the coil 64 are flat, the article 10 can be arranged in the cavity in two orientations (ie, a second orientation and an orientation opposite to the second orientation). 38 in. These two orientations can heat the substrate of article 10 more efficiently than any other orientation, such as the first orientation, when facing flat induction heating coil 64 . With this arrangement, the user can more easily rotate the article 10 to a desired orientation, since the user only needs to rotate the article a half-cycle.

Fig. 3 (a), Fig. 3 (b) and Fig. 3 (c) are partial illustrations showing that when the aerosol-generating article 10 is accommodated in the cavity 38 of the aerosol-generating device 30 to the greatest extent, with The distal end I of the aerosol-generating article 10 of the substrate, the blade-shaped susceptor 17 and the self-sealing airflow barrier 28, and the flat induction heating coil 64 of the aerosol-generating device 30. As discussed above, in order to position the blade-shaped flat susceptor 17 parallel to the flat induction heating coil 64, the orientation element 28a is configured to have a cylindrical shape whose cross-section allows the insertion of the article 10 into the cavity 38 of the device 30 in only two orientations. . More specifically, the orientation element 28a may have the shape of a polyhedron (preferably a cube, an irregular cylinder or a polygonal prism). In other embodiments, as shown in FIG. 3( c ), the susceptor 17 and the coil 64 may have other shapes, such as a curved leaf shape. In such cases, the orientation element 28a should have a shape, in this embodiment a cylinder with a triangular cross-section, so that the article can only be accommodated in the cavity 38 in only one orientation, so that the susceptor 17 can be brought close to the sensing The heating coil 64 is positioned and properly aligned therewith.
