Description

[Technical Field]

[0001] The present invention relates to an aerosol generating device, an aerosol generating system, a method for generating an aerosol, a method for fabricating an aerosol generating device, and an aerosol delivery device.

[0002] Smoking articles, such as cigarettes and cigars, burn tobacco to produce tobacco smoke during use. Attempts have been made to provide alternatives to these items by creating products that release compounds without combustion. Examples of such products are so-called "heat-and-burn" products, or tobacco heating devices or products, which release compounds by heating rather than burning a material. The material may be, for example, tobacco or other non-tobacco products, which may or may not contain nicotine.

[0003] Aerosol delivery systems are known that encompass the aforementioned devices or products. Typical systems use a heater to generate an aerosol from a suitable medium, which is then inhaled by a user. Often, the medium used must be replaced or changed to deliver and inhale different aerosols. It is known to use an induction heating system as a heater to generate an aerosol from a suitable medium. An induction heating system generally consists of a magnetic field generating device for generating a varying magnetic field and a susceptor or heating material that can be heated by the penetration of the varying magnetic field to heat the suitable medium.

[0004] Many different magnetic field generating devices, such as three-dimensional inductor coils, are known. However, various constraints, such as available space, device size, and required power, limit the types of magnetic field generating devices. Furthermore, various parameters limit the efficiency of inductive coupling between the magnetic field generating device and the susceptor or heating material. For example, such parameters include the spacing between the magnetic field generating device and the susceptor or heating material, or their relative area sizes and orientations.

[0038] [Figure 1] FIG. 1 is a schematic perspective view of an example of a planar non-helical inductor coil for use in an aerosol generating device. [Figure 2] FIG. 1 is a schematic side view of an example electrically heated aerosol generating system. [Figure 3] 1 is a schematic perspective view of an example of a planar non-helical inductor coil configuration in the form of a mandrel loop or loop according to one embodiment. FIG. Detailed Description

[0039] As used herein, the term "aerosol-forming material," sometimes referred to as "aerosolizable material," includes materials that, upon heating, provide volatile components, typically in the form of a vapor or an aerosol. "Aerosolizable material" may be tobacco-free or tobacco-containing. "Aerosolizable material" may include, for example, one or more of tobacco itself, tobacco derivatives, expanded tobacco, reconstituted tobacco, tobacco extract, homogenized tobacco, or tobacco substitutes. Aerosolizable material may be in the form of ground tobacco, cut rag tobacco, extruded tobacco, reconstituted tobacco, reconstituted aerosolizable material, liquid, gel, solid, gelled sheet, powder, beads, granules, or chunks. "Aerosolizable material" may also include other non-tobacco products, which may or may not contain nicotine, depending on the product. "Aerosolizable material" may also include one or more humectants, such as glycerol or propylene glycol.

[0040] The susceptor is a material that can be heated by the penetration of a varying magnetic field, such as an alternating magnetic field. The heating material can be a conductive material, such that the penetration of the varying magnetic field into the heating material results in induction heating of the heating material. The heating material can be a magnetic material, such that the penetration of the varying magnetic field into the heating material results in magnetic hysteresis heating of the heating material. The heating material can be both conductive and magnetic, such that the heating material can be heated by both heating mechanisms.

[0041] Induction heating is a process in which a conductive object is heated by penetrating a changing magnetic field into the object. This process is explained by Faraday's law of electromagnetic induction and Ohm's law. An induction heater can include an electromagnet and a device for passing a changing current, such as an alternating current, through the electromagnet. When the electromagnet and the object to be heated are positioned relative to each other so that the changing magnetic field generated by the electromagnet penetrates the object, one or more eddy currents are generated within the object. The object has a resistance to the flow of current.

[0042] Therefore, when such eddy currents are generated in the object, they flow against the object's electrical resistance, causing the object to heat up, a process known as Joule, ohmic, or resistive heating.

[0043] In one example, the susceptor is in the form of a closed circuit. It has been found that when the susceptor is in the form of a closed circuit, there is a stronger magnetic coupling between the susceptor and the electromagnet in use, resulting in increased or improved Joule heating.

[0044] Magnetic hysteresis heating is the process by which an object made from a magnetic material is heated by the penetration of a changing magnetic field. Magnetic materials can be thought of as containing many atomic-scale magnets, or magnetic dipoles. When a magnetic field penetrates such a material, the magnetic dipoles align along the field. Thus, when a changing magnetic field, such as an alternating magnetic field produced by an electromagnet, penetrates a magnetic material, the orientation of the magnetic dipoles changes with the applied changing magnetic field. This change in orientation of the magnetic dipoles generates heat within the magnetic material.

[0045] When an object is both conductive and magnetic, subjecting it to a varying magnetic field can cause both Joule heating and magnetic hysteresis heating. Furthermore, magnetic materials can be used to enhance the magnetic field, thereby enhancing Joule heating.

[0046] In each of the above processes, because heat is generated within the object itself rather than by conduction from an external heat source, rapid temperature rise and more uniform heat distribution within the object can be achieved, particularly by appropriate selection of the object's material and geometry, and the magnitude and orientation of the varying magnetic field relative to the object. Furthermore, induction heating and magnetic hysteresis heating do not require a physical connection between the varying magnetic field source and the object, thereby increasing design freedom and control of the heating profile and reducing costs.

[0047] Referring to Figure 1, there is shown a schematic perspective view of an example of an inductive coil arrangement according to one embodiment. The inductive coil arrangement 1 is for use with an aerosol generation system that includes an aerosol generation device, such as device 100, as shown in Figure 2 and further described below.

[0048] The induction coil arrangement 1 comprises a board, panel, or plate 10 and two planar, non-helical inductor coils 21 (the other coil is not shown) of a conductive material such as copper. Alternatively, there may be only one inductor coil 21. In use, as described in more detail below, a varying current (e.g., an alternating current) is passed through each of the coils 21 to generate a varying magnetic field (e.g., an alternating magnetic field) that can penetrate a heating element and be used to heat the heating element.

[0049] The plate 10 has a first side 11 and an opposite second side 12. The first side 11 and the second side 12 of the plate 10 face in opposite directions. In this embodiment, the plate 10 is substantially planar, and the first and second sides 11 and 12 are the major sides of the plate 10. The plate 10 may be made of a non-conductive material, such as a plastic material, to electrically insulate the coils 21 from one another. In this embodiment, the plate 10 is made of FR-4, a composite material made of woven glass fiber with a flame-retardant epoxy resin binder. A first coil of the planar non-spiral inductor coil 21, which may include a conductive material, may be attached to the first side 11 of the plate 10, and a second coil of the planar non-spiral inductor coil 21, which may include a conductive material, may be attached to the second side 12 of the plate 10. Thus, the plate 10 is positioned between the coils 21.

[0050] An opening 13 may be provided in the plate 10. In use, an aerosol product and / or a susceptor may be introduced into the opening 13.

[0051] These planar non-helical inductor coils 21, or at least one of them, may be in the form of a square or rectangular spiral.

[0052] The coil 21 may be affixed to the plate 10 in any suitable manner. In this embodiment, the induction coil arrangement 1 is formed from a printed circuit board (PCB), and thus the first and second planar non-helical coils 21 are formed during PCB manufacture by printing a conductive material onto the first and second sides 11, 12 of the board or plate 10, respectively, and then removing selected portions of the conductive material (such as by etching) so that a pattern of the conductive material in the form of the first and second flat helical coils 21 remains on the plate 10. The first and second planar non-helical coils 21 are therefore thin films or coatings of conductive material on the plate 10.

[0053] The first and second planar non-helical coils 21 may be formed as open loops having a first end 21a and a second end 21b.

[0054] Alternatively, in the absence of plate 10, these coils may be insulated or separated from one another, i.e., not connected or formed from a PCB.

[0055] Thus, the induction coil configuration 1 of this embodiment comprises a laminate having a first layer (comprising the first planar non-helical coil 21), a second layer (comprising the second planar non-helical inductor coil), and a third layer (plate 10) intermediate the first and second layers. Thus, the plate 10 spaces the first and second layers apart. Because the plate 10 is made of a non-conductive material, the coils 21 are electrically isolated from one another (other than by the conductive connectors 30, discussed below). That is, the coils 21 do not contact one another. In other embodiments, the coils 21 may be electrically isolated from one another in a different manner, such as by an air gap between the coils 21. In some embodiments, the coils 21 may be provided on the plate 10 in any other suitable manner, such as being pre-formed and then attached to the plate 10.

[0056] In some embodiments, plate 10 may be formed from something other than a layer of a PCB. For example, plate 10 may be a layer or sheet of material, such as a resin or adhesive, that may have been dried, cured, or solidified.

[0057] As discussed above, using a coil formed from a thin, printed conductive material eliminates the need for LITZ® wire. Litz wire is composed of many strands of very thin wire bound together in a braid to overcome the effects of reduced skin depth at high excitation frequencies. Because the tracks on the PCB are as thin as 25 μm (typically about 38 μm thick for 1 oz. copper and about 76 μm thick for 2 oz. copper), high-frequency performance can be comparable to that of a comparable cross-sectional area of ​​Litz® wire, but without the problems associated with brittleness, forming Litz® wire, or connecting to other components.

[0058] The first and second planar non-helical coils 21 are exposed on the plate 10, which helps to allow dissipation of any heat generated in the coils 21 during use. However, in other embodiments, the first and second planar non-helical coils 21 can instead be embedded within the material forming the plate 10, which helps to protect the coils 21 from damage during transport, storage, and use.

[0059] Referring to Figure 2, a schematic cross-sectional side view of an example aerosol generation system is shown. The system 1 comprises an aerosol generation device 100 and an aerosol product 210 comprising an aerosolizable material 211. The aerosolizable material 211 may be, for example, any type of aerosolizable material discussed herein. In this example, the aerosol generation device 100 is a tobacco heating product (also known in the art as a tobacco heating device or a non-combustion heating device).

[0060] In some examples, the aerosolizable material 211 is a non-liquid material. In some examples, the aerosolizable material 211 is a gel. In some examples, the aerosolizable material 211 includes tobacco. However, in other examples, the aerosolizable material 211 may consist of tobacco, consist substantially entirely of tobacco, include tobacco and aerosolizable materials other than tobacco, include aerosolizable materials other than tobacco, or be tobacco-free. In some examples, the aerosolizable material 211 may include a vapor or aerosol-forming agent or a humectant (e.g., glycerol, propylene glycol, triacetin, or diethylene glycol). In some examples, the aerosolizable material 211 includes a reconstituted aerosolizable material, such as reconstituted tobacco.

[0061] In some examples, aerosolizable material 211 is substantially cylindrical with a substantially circular cross-section and a longitudinal axis, while in other examples, aerosolizable material 211 may have another cross-sectional shape and / or may not be elongated.

[0062] The axial length of the aerosolizable material 211 of the aerosol product article 210 may be, for example, between 8 mm and 120 mm. For example, the axial length of the aerosolizable material 211 may be greater than 9 mm, or 10 mm, or 15 mm, or 20 mm. For example, the axial length of the aerosolizable material 211 may be less than 100 mm, or 75 mm, or 50 mm, or 40 mm.

[0063] In some examples, such as the example shown in FIG. 2 , the aerosol production article 210 includes a filter arrangement 212 for filtering aerosol or vapor emitted from the aerosolizable material 211 during use. Alternatively or additionally, the filter arrangement 212 may be for controlling the pressure drop across the length of the article. The filter arrangement 212 may include one or more filters. The filter arrangement 212 may be of any type used in the tobacco industry. For example, the filter may be made of cellulose acetate. In some examples, the filter arrangement 212 is substantially cylindrical with a substantially circular cross-section and a longitudinal axis. In other examples, the filter arrangement 212 may have another cross-sectional shape and / or may not be elongated.

[0064] In some examples, the filter composition 212 abuts a longitudinal end of the aerosolizable material 211. In other examples, the filter composition 212 may be spaced apart from the aerosolizable material 211, such as by a gap and / or one or more additional components of the aerosol product article 210. In some examples, the filter composition 212 may include an additive or flavor source (such as a capsule or thread containing the additive or flavor), which may be held by the body of the filtration material or between two bodies of filtration material, for example.

[0065] The aerosol product article 210 may also include a wrapper (not shown) wrapped around the aerosolizable material 211 and the filter element 212 to hold the filter element 212 against the aerosolizable material 211. The wrapper may be wrapped around the aerosolizable material 211 and the filter element 212 such that the free ends of the wrapper overlap one another. The wrapper may form part or all of the circumferential outer surface of the aerosol product article 210. The wrapper may be made from any suitable material, such as paper, cardboard, or recycled aerosolizable material (e.g., reconstituted tobacco). The paper may be tipping paper, as is known in the art. The wrapper may also include an adhesive (not shown) that adheres the overlapped free ends of the wrapper to one another and helps prevent the overlapped free ends from separating. In other examples, the adhesive may be omitted, or the wrapper may take a different form than that described. In other examples, the filter element 212 may be held against the aerosolizable material 211 by a connector other than the wrapper, such as an adhesive. In some examples, the filter arrangement 212 may be omitted.

[0066] The aerosol generation device 100 comprises a heated region 110 for receiving at least a portion of the aerosol product article 210, an outlet 120 through which, in use, the aerosol can be delivered from the heated region 110 to a user, and a heating apparatus 130 for generating an aerosol by heating the aerosol product article 210 when the aerosol product article 210 is at least partially disposed within the heated region 110. In some examples, such as that shown in FIG. 1 , the aerosol can be delivered from the heated region 110 to a user through the aerosol product article 210 itself, rather than through any gaps adjacent to the aerosol product article 210. Nevertheless, in such examples, the aerosol still passes through the outlet 120 while traveling within the aerosol product article 210.

[0067] Device 100 may define at least one air inlet (not shown) fluidly connecting heated region 110 with the exterior of device 100. A user can inhale the volatile component(s) of the aerosolizable material by drawing the volatile component(s) from heated region 110 through aerosol product article 210. Once the volatile component(s) are removed from heated region 110 and aerosol product article 210, air can be drawn into heated region 110 through air inlet(s) of device 100.

[0068] In this example, the heating region 110 extends along an axis AA and is sized and shaped to accommodate only a portion of the aerosol product article 210. In this example, the axis AA is a central axis of the heating region 110. Further, in this example, the heating region 110 is elongated, and thus the axis AA is a longitudinal axis AA of the heating region 110. The aerosol product article 210 is at least partially insertable into the heating region 110 through the outlet 120 and protrudes from the heating region 110 through the outlet 120 during use. In other examples, the heating region 110 may or may not be elongated and may be sized to accommodate the entire aerosol product article 210. In some such examples, the device 100 may be configured to cover the outlet 120 and may include a mouthpiece through which aerosol can be drawn from the heating region 110 and the aerosol product article 210.

[0069] In this example, when aerosol product article 210 is at least partially disposed within heated region 110, different portions 211a-211e of aerosolizable material 11 are disposed at different respective locations 110a-110e within heated region 110. In this example, these locations 110a-110e are at different respective axial locations along axis AA of heated region 110. Furthermore, in this example, because heated region 110 is elongated, locations 110a-110e can be considered to be different longitudinally spaced locations along the length of heated region 110. In this example, aerosol product article 210 can be considered to include five such portions 211a-211e of aerosolizable material 11 disposed at first location 110a, second location 110b, third location 110c, fourth location 110d, and fifth location 110e, respectively. More specifically, the second position 110b is fluidly disposed between the first position 110a and the outlet 120, the third position 110c is fluidly disposed between the second position 110b and the outlet 120, the fourth position 110d is fluidly disposed between the third position 110c and the outlet 120, and the fifth position is fluidly disposed between the fourth position 110d and the outlet 120.

[0070] Heating apparatus 130 includes a plurality of heating units 140a-140e, each of which is capable of heating a respective one of portions 211a-211e of aerosolizable material 11 to a temperature sufficient to aerosolize its components when aerosol product article 210 is at least partially disposed within heating zone 110. The plurality of heating units 140a-140e may be axially aligned with one another along axis AA. Each of portions 211a-211e of aerosolizable material 11 thus heatable may have a length along axis AA of 1 millimeter to 20 millimeters, such as 2 millimeters to 10 millimeters, 3 millimeters to 8 millimeters, or 4 millimeters to 6 millimeters.

[0071] As used herein, the term "heating unit" corresponds to a planar non-helical inductor coil such as described in any of the previous examples described with reference to FIG.

[0072] The heating apparatus 130 in this example includes five heating units 140a-140e, namely, first heating unit 140a, second heating unit 140b, third heating unit 140c, fourth heating unit 140d, and fifth heating unit 140e. The heating units 140a-140e are at different axial positions along the axis AA of the heating zone 110. Furthermore, in this example, because the heating zone 110 is elongated, the heating units 140a-140e can be considered to be at different longitudinally spaced positions along the length of the heating zone 110. More specifically, second heating unit 140b is disposed between first heating unit 140a and outlet 120, third heating unit 140c is disposed between second heating unit 140b and outlet 120, fourth heating unit 140d is disposed between third heating unit 140c and outlet 120, and fifth heating unit 140e is disposed between fourth heating unit 140d and outlet 120. In other examples, heating apparatus 130 can include more than five heating units 140a-140e, or fewer than five heating units, such as only four, only three, only two, or only one. The number of portion(s) of aerosolizable material 211 heatable by each heating unit(s) can vary correspondingly.

[0073] Heating units 140a-140e in this example include planar non-helical inductor coils.

[0074] The heating device 130 also includes a controller 135 configured to operate the heating units 140a-140e to heat respective portions 211a-211e of the aerosolizable material 211 during use. In this example, the controller 135 is configured to operate the heating units 140a-140e independently of one another, such that respective portions 211a-211e of the aerosolizable material 211 can be independently heated. This may be desirable for progressive heating of the aerosolizable material 211 during use. Furthermore, in examples in which the portions 211a-211e of the aerosolizable material 211 have different respective morphologies or properties, such as different tobacco blends and / or different applied or inherent flavors, being able to independently heat the portions 211a-211e of the aerosolizable material 211 may enable heating of selected portions 211a-211e of the aerosolizable material 211 at different times during a use session to generate aerosols having predetermined properties depending on time. In some examples, the heating device 130 may also be operable in one or more modes in which the controller 135 is configured to operate two or more of the heating units 140a-140e simultaneously, such as all of the heating units 140a-140e, during a usage session.

[0075] In this example, the heating units 140a-140e include respective planar non-helical induction coils configured to generate respective varying magnetic fields, such as alternating magnetic fields. Thus, the heating device 130 can be considered to include a magnetic field generator, and the controller 135 can be considered to be a device operable to apply a varying current to the inductor of each of the heating units 140a-140e.

[0076] Furthermore, in this example, device 100 comprises a susceptor 190 that is heatable by penetration of a varying magnetic field, and is configured to, in use, heat heating region 110 and aerosol product article 210 therein. That is, these portions of susceptor 190 are heatable by penetration of the respective varying magnetic fields, and thereby heat respective portions 211a-211e of aerosolizable material 11 at respective locations 110a-110e of heating region 110.

[0077] In some examples, the susceptor 190 is made of or includes aluminum. However, in other examples, the susceptor 190 may include one or more materials selected from the group consisting of an electrically conductive material, a magnetic material, and a magnetically conductive material. In some examples, the susceptor 190 may include a metal or a metal alloy. In some examples, the susceptor 190 may include one or more materials selected from the group consisting of aluminum, gold, iron, nickel, cobalt, conductive carbon, graphite, steel, plain carbon steel, mild steel, stainless steel, ferritic stainless steel, molybdenum, silicon carbide, copper, and bronze. Other material(s) may be used in other examples.

[0078] In some examples, such as those in which the susceptor 190 comprises iron, e.g., steel (e.g., mild steel or stainless steel), or aluminum, the susceptor 190 may include a coating that helps prevent corrosion or oxidation of the susceptor 190 during use. Such coatings may include, for example, nickel plating, gold plating, or a ceramic or inert polymer coating.

[0079] In this example, the susceptor 190 is tubular and surrounds the heating region 110. Indeed, in this example, the inner surface of the susceptor 190 partially defines the heating region 110. The inner cross-sectional shape of the susceptor 190 may be circular or a different shape, such as oval, polygonal, square, rectangular, or irregular. In other examples, the susceptor 190 may take a different form, such as a non-tubular structure that also partially surrounds the heating region 110, or a protruding structure, such as a rod, pin, or blade, that penetrates the heating region 110. In some examples, the susceptor 190 may be replaced by multiple susceptors, each of which is heatable by the penetration of a respective one of the varying magnetic fields, thereby heating a respective one of the portions 211a-211e of the aerosolizable material 11. Each of the multiple susceptors may be tubular or may take one of the other forms discussed herein for the susceptor 190, for example. In a further example, device 100 may lack susceptor 190, and aerosol product article 210 may comprise one or more susceptors heatable by the penetration of a varying magnetic field to heat respective portions 211a-211e of aerosolizable material 11. Each of one or more susceptors 190 of aerosol product article 210 may take any suitable form, such as a structure wrapped around or otherwise surrounding aerosolizable material 211 (e.g., a metal foil such as aluminum foil), a structure disposed within aerosolizable material 211, or a group of particles or other elements mixed with aerosolizable material 211. In examples where apparatus 100 lacks susceptor 190, susceptor 190 may be replaced by a heat-resistant tube that partially defines heating region 110. Such a heat-resistant tube may be made, for example, from polyether ether ketone (PEEK) or a ceramic material.

[0080] In another example, a planar non-helical induction coil may be positioned so that it is parallel to the susceptor or susceptors and the axis AA, in other words, so that the planar face or side of the coil is parallel to the axis AA, e.g., so that the aerosol product article 210 is not positioned axially relative to the coil.

[0081] In other examples, the induction coil can be configured to heat the entire length or sides of the susceptor.

[0082] In other examples, the planar non-helical induction coil may be configured to form a square or rectangular enclosure around the susceptor 190 or susceptors 190 such that the entire susceptor or susceptors are heated.

[0083] In this example, the heating device 130 includes a power source (not shown) and a user interface (not shown) for user operation of the device. The power source in this example is a rechargeable battery. In other examples, the power source may be something other than a rechargeable battery, such as a non-rechargeable battery, a capacitor, a battery-capacitor hybrid, or a connection to a mains power source.

[0084] In this example, controller 135 is electrically connected between the power source and heating units 140a-140e. In this example, controller 135 is also electrically connected to the power source. More specifically, in this example, controller 135 is for controlling the supply of power from the power source to heating units 140a-140e. In this example, controller 135 comprises an IC, such as an integrated circuit (IC) on a printed circuit board (PCB). In other examples, controller 135 may take different forms. In this example, controller 135 is operated by a user operating a user interface. The user interface may comprise push buttons, toggle switches, dials, a touch screen, or the like. In other examples, the user interface may be remote and wirelessly connected to the rest of aerosol delivery device 100, such as via Bluetooth®.

[0085] In this example, a user operates the user interface, causing the controller 135 to apply an alternating current to at least one planar non-spiral inductor in each of the heating units 140a-140e. This causes the inductor to generate an alternating magnetic field. The inductor and the susceptor 190 are positioned relative to each other so that the varying magnetic field generated by the inductor penetrates the susceptor 190. If the susceptor 190 is conductive, this penetration generates one or more eddy currents in the susceptor 190. The eddy currents flow within the susceptor 190 against the susceptor's electrical resistance, causing the susceptor 190 to heat by Joule heating. If the susceptor 190 is magnetic, the orientation of the magnetic dipoles in the susceptor 190 changes with changes in the applied magnetic field, thereby generating heat in the susceptor 190.

[0086] The device 100 may include a temperature sensor (not shown) for detecting the temperature of the heating chamber 110, the susceptor 190, or the aerosol product article 210. The temperature sensor may be communicatively connected to the controller 135, such that the controller 135 can monitor the temperature of the heating chamber 110, the susceptor 190, or the aerosol product article 210, respectively, based on information output by the temperature sensor. In another example, the temperature may be detected and monitored by measuring an electrical characteristic of the system, such as a change in the current in the heating units 140a-140e. Based on one or more signals received from the temperature sensor, the controller 135 can adjust the characteristic of the fluctuating or alternating current as needed to ensure that the temperature of the heating chamber 110, the susceptor 190, or the article, respectively, remains within a predetermined temperature range. This characteristic may be, for example, amplitude, frequency, or duty cycle. Within a predetermined temperature range, the aerosolizable material 211 in the aerosol product 210 disposed in the heating chamber 110 is heated sufficiently to volatilize at least one component of the aerosolizable material 211, in use, without burning the aerosolizable material 211. Thus, the controller 135, and the device 100 as a whole, are configured to heat the aerosolizable material 211 to volatilize at least one component of the aerosolizable material 211 without burning the aerosolizable material 211. This temperature range may be from about 50°C to about 350°C, such as from about 100°C to about 300°C, or from about 150°C to about 280°C. In other examples, the temperature range may be outside of these ranges. In some examples, the upper limit of the temperature range may be greater than 350°C. In some examples, the temperature sensor may be omitted.

[0087] In the foregoing example, the magnitude or extent of the fluctuating magnetic field measured in the direction of axis AA is relatively small, and as a result, the portion of susceptor 190 penetrated by the fluctuating magnetic field during use is correspondingly small. Therefore, it may be desirable for susceptor 190 to have a thermal conductivity sufficient to increase the proportion of susceptor 190 that is heated by thermal conduction as a result of the penetration of the fluctuating magnetic field, thereby correspondingly increasing the proportion of aerosolizable material 211 that is heated by operation of each of heating units 140a-140e. It has been found desirable to provide susceptor 190 with a thermal conductivity of at least 10 W / m / K, optionally at least 50 W / m / K, and even optionally at least 100 W / m / K. In this example, susceptor 190 is made of aluminum and has a thermal conductivity greater than 200 W / m / K, such as 200-250 W / m / K, e.g., about 205 W / m / K or 237 W / m / K. As mentioned above, the length of each of portions 211a-211e of aerosolizable material 11 along axis AA may be between 1 millimeter and 20 millimeters, such as between 2 millimeters and 10 millimeters, between 3 millimeters and 8 millimeters, or between 4 millimeters and 6 millimeters.

[0088] It will be appreciated that for a given duration of a heating session, the greater the number of heating units and associated portions of aerosolizable material 211, the greater the opportunity to generate aerosol from “fresh” or unused portions of the aerosolizable material 211 extending along a given axial length. Alternatively, for a given duration of heating each portion of the aerosolizable material 211, the greater the number of heating units and associated portions of the aerosolizable material 211, the longer the heating session may be. It should be appreciated that the duration that individual heating units may be activated may be adjusted (e.g., shortened) to adjust (e.g., shorten) the overall heating session, while the power supplied to the heating elements may be adjusted (e.g., increased) to reach operating temperature more quickly. A balance may be struck between the number of heating units (which may determine the number of “fresh puffs”), the overall session length, and the achievable power supply (which may be determined by the characteristics of the power source).

[0089] Referring now to Figure 3, there is shown a schematic perspective view of an example of a planar non-helical coil in the form of a mandrel loop or loop formed on a PCB, according to one embodiment. The mandrel loop can be understood to comprise an open loop having a first end and a second end. The inductive coil arrangement 50 is for use with an aerosol generation system such as that described above with respect to Figure 2.

[0090] The induction coil arrangement 50 comprises a PCB 52, a planar non-helical inductor coil arranged on the PCB 52 in the form of a mandrel loop or loop 54, and an insulator 56 disposed over the mandrel loop or loop 54. The mandrel loop or loop 54 is formed of a conductive material such as copper. As will be described in more detail below, in use, a varying electrical current (e.g., an AC current) is passed through the mandrel loop or loop 54 to generate a varying magnetic field (e.g., an AC magnetic field) that can be used to penetrate and heat a heating element, such as the susceptor 190 of FIG. 2 .

[0091] Although this embodiment includes a PCB 52, other embodiments are contemplated in which the mandrel loop or loops 52 are not disposed on the PCB. Instead, only the mandrel loop or loops 54 are present, or only the mandrel loop or loops 54 and the insulator 56 are present.

[0092] In this particular embodiment, the mandrel loop or loop 54 comprises only a single turn, however, other embodiments are contemplated in which the mandrel loop or loop 54 comprises more than one turn, such as two turns, three turns, four turns, or more than four turns.

[0093] Insulator 56 in this embodiment is in the form of a planar plate. Insulator 56 may be made from a non-conductive material, such as a plastic material, so as to electrically insulate mandrel loop or loops 54. In this embodiment, insulator 56 is made from FR-4, a composite material made of woven fiberglass cloth with a flame-retardant epoxy resin binder.

[0094] In some examples, when used in an aerosol generating system, multiple induction coil configurations 50 as described above may be used. The multiple induction coil configurations 50 may be configured in a multi-layer structure. In one example, only a single PCB 52 is present. According to this embodiment, a first mandrel loop or loop 54 may be disposed on the PCB 52, and a first insulator 56 may be disposed on the first mandrel loop or loop 52. A second mandrel loop or loop 54 may be disposed on the first insulator 56, and a second insulator 56 may be provided on the second mandrel loop or loop 54. This configuration may be repeated as many times as necessary until specific requirements are met, for example, to achieve a desired amount of magnetic flux density when a varying current (e.g., an alternating current) is passed through the multiple mandrel loops or loops 54.

[0095] In another example, rather than a single PCB 52, each layer may include its own PCB 52, mandrel loop or loops 54, and insulator 56.

[0096] In other examples, there is no respective PCB 52 or insulator 56, and instead multiple mandrel loops or loops 54 are configured in multiple layers. In such examples, the mandrel loops or loops 54 may be electrically isolated from each other in different ways, such as by air gaps. In other examples, only one mandrel loop or loop 54 is used.

[0097] Turning now to the example where PCB 52 is present, mandrel loop or loops 54 may be affixed to PCB 52 in any suitable manner. In the embodiment shown in Figure 3, induction coil configuration 50 is formed from a printed circuit board (PCB), and thus mandrel loop or loops 54 are formed during manufacture of PCB 52 by printing a conductive material onto each of first and second sides 11 of PCB 52 and then removing (such as by etching) selected portions of the conductive material to leave a pattern of conductive material in the form of mandrel loop or loops. Mandrel loop or loop 54 is therefore a thin film or coating of conductive material on PCB 52.

[0098] It will therefore be apparent that any of the example mandrel loops or loop 54 configurations discussed above can be used as a heating unit as described in the system of FIG.

[0099] In some embodiments, the aerosol-generating system is an e-cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0100] In some embodiments, the aerosol-generating system is a tobacco heating system, also known as a non-combustion heating system.

[0101] In some embodiments, the aerosol-generating system is a hybrid system for generating an aerosol using a combination of aerosol-generating materials, one or more of which may be heated. Each of the aerosol-generating materials may be, for example, in solid, liquid, or gel form and may or may not contain nicotine. In some embodiments, the hybrid system comprises a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may, for example, include tobacco or a non-tobacco product.

[0102] Typically, an aerosol generating system may comprise an aerosol generating device and an article for use with the aerosol generating device, however, it is contemplated that an article that itself comprises means for providing energy to an aerosol generating component may itself form an aerosol generating system.

[0103] In some embodiments, the aerosol generating device may comprise a power source and a controller. The power source may be, for example, an electrical power source.

[0104] In some embodiments, an article for use with an aerosol-generating device may comprise an aerosol-generating material, an aerosol-generating component, an aerosol-generating region, a mouthpiece, and / or a region for receiving the aerosol-generating material.

[0105] In some embodiments, the aerosol-generating component is a heater capable of interacting with the aerosol-generating material to release one or more volatile components from the aerosol-generating material to form an aerosol.

[0106] In some embodiments, the substance to be delivered may be an aerosol-forming material, which may also be referred to herein as an aerosol-forming material, is a material that can generate an aerosol when, for example, heated, irradiated, or in any other way energized.

[0107] In some embodiments, the aerosol product article 210 is a consumable item or article for use with a non-combustible aerosol delivery device. Once all or substantially all of the volatilizable component(s) of the aerosolizable material 211 in the aerosol product article 210 have been consumed, a user can remove the aerosol product article 210 from the heating region 110 of the aerosol generation device 100 and discard the article 210. The user can subsequently reuse the aerosol generation device 100 with another aerosol product article 210. However, in other embodiments, the aerosol product article 210 may not be consumable with respect to the heating device 130. That is, once the volatilizable component(s) of the aerosolizable material 211 have been consumed, the heating device 130 and the aerosol product article 210 may be discarded together.

[0108] In some embodiments, the aerosol product article 210 is sold, supplied, or otherwise provided separately from the aerosol generating device 100 in which the article 210 can be used. However, in some examples, the aerosol generating device 100 and one or more aerosol product articles 210 may be provided together as a system, such as a kit or assembly, possibly with additional components such as cleaning equipment.

[0109] In some embodiments, the aerosol generating device 100 further comprises a flux concentrator, such as a magnetically permeable core. In some embodiments, an inductor coil, such as those described above, may be wound around or encased in a portion of the flux concentrator. In other embodiments, the inductor coil may be adjacent to or embedded in the flux concentrator.

[0110] For example, the flux concentrator or magnetically permeable core concentrates the magnetic flux generated by the inductor coil during use, creating a stronger magnetic field. Additionally, the magnetically permeable core helps direct the magnetic flux toward its intended target, which in the embodiments discussed above is one or more susceptors. In some embodiments, the coil may be wound around only a portion (i.e., not all) of the flux concentrator. In some embodiments, the magnetically permeable core can have a high magnetic permeability and a low electrical conductivity. The low electrical conductivity helps prevent eddy currents from forming in the magnetically permeable core during use, which helps prevent the magnetically permeable core from heating during use.

[0111] The magnetically permeable core may include or consist of ferrite. The ferrite may include, for example, iron oxide combined with nickel and / or zinc and / or manganese. The ferrite may be considered a "soft ferrite" with low coercivity or a "hard ferrite" with high coercivity. Examples of usable soft ferrites are manganese-zinc ferrites with the formula MnaZn(ia)Fe2O4 and nickel-zinc ferrites with the formula NiaZn(ia)Fe2O4. However, in each variation on these embodiments, the magnetically permeable core may be made from different material(s). For example, in some embodiments, the magnetically permeable core may comprise multiple layers of conductive material insulated from each other by non-conductive material. The magnetically permeable core may have dozens or even hundreds of layers of conductive material insulated from each other by non-conductive material. In embodiments comprising multiple induction coils, multiple flux concentrators or magnetically permeable cores may be provided, each one of the multiple flux concentrators or magnetically permeable cores corresponding to a respective induction coil of the multiple induction coils.

[0112] The aerosol generation device 100, aerosol generation system, and inductor coil according to various embodiments prove to be particularly useful when generating aerosol from a substantially flat aerosol product, particularly an aerosol product comprising a substantially flat consumable item.

[0113] The substantially flat consumable may be provided in either an array or a circular configuration. Other configurations are also contemplated.

[0114] The substantially flat consumable product may comprise a plurality of discrete portions of aerosolizable material. The plurality of discrete portions of aerosolizable material may be arranged in an array or grid configuration. The plurality of discrete portions of aerosolizable material may be arranged in a circular pattern.

[0115] In some embodiments, for example where a substantially planar consumable is provided in the form of an array, multiple heating regions may be provided, for example, according to one embodiment, one heating region may be provided per portion, pixel, or region / segment of the consumable.

[0116] In another embodiment, a substantially flat consumable may be rotated so that segments of the consumable are heated by similarly shaped heaters. According to this embodiment, a single heating zone may be provided.

[0117] In some embodiments, the substantially planar consumable can be moved in one or more directions relative to the heating region.

[0118] In particular, an inductor coil according to various embodiments may be provided as part of a non-combustion aerosol delivery device configured to heat a consumable without combustion as part of a non-combustion aerosol delivery system. In particular, the consumable may comprise a plurality of individual portions of an aerosol-generating material, each of the individual portions including less than about 15 mg of water.

[0119] In some embodiments, the aerosol-generating material is formed as a sheet. In some cases, the sheet of aerosol-generating material may be incorporated into an assembly or consumable in the form of a sheet; for example, multiple individual portions may be multiple sheets. The sheet of aerosol-generating material may be incorporated as a flat sheet, as a grouped or bundled sheet, as a pressed sheet, or as a rolled sheet (i.e., in the form of a tube). In some such cases, the aerosol-generating material of these embodiments may be included in the aerosol-generating consumable / assembly as a sheet, such as a sheet surrounding a rod of aerosol-generating material (e.g., tobacco). For example, the sheet of aerosol-generating material may be formed into a wrapping paper that surrounds the aerosol-generating material, such as tobacco. In other cases, the sheet may be shredded and then mixed with aerosol-generating material, such as cut rag tobacco, and incorporated into the assembly. In such cases, the consumable of the present invention retains the ability to aerosolize 15 mg or less of water per inhalation by a user when the aerosol-generating material is heated to at least 120°C.

[0120] The consumable may include a support on which the aerosol-generating material is provided. The support serves as a support for the aerosol-generating material to form, facilitating manufacturing. The support can provide tensile strength to the aerosol-generating material, facilitating handling. In some cases, multiple individual portions of the aerosol-generating material are deposited on such a support. In some cases, multiple individual portions of an amorphous material are deposited on such a support. In some cases, the individual portions of the aerosol-generating material are deposited on such a support such that each individual portion can be heated and aerosolized separately. In an exemplary embodiment, the consumable includes multiple individual portions of the aerosol-generating material, the individual portions being provided on a support, each individual portion containing less than 15 mg of water.

[0121] The individual portions of aerosol-generating material are preferably provided on a support such that each individual portion can be separately heated and aerosolized. It has been found that consumables having this configuration are able to deliver a consistent aerosol to the user with each puff.

[0122] In some cases, the substrate may be formed from a material selected from metal foil, paper, carbon paper, greaseproof paper, ceramic, carbon allotropes such as graphite and graphene, plastic, cardboard, wood, or a combination thereof. In some cases, the substrate may include or consist of a tobacco material, such as a sheet of reconstituted tobacco. In some cases, the substrate may be formed from a material selected from metal foil, paper, cardboard, wood, or a combination thereof. In some cases, the substrate itself is a laminated structure comprising layers of materials selected from the foregoing list. In some cases, the substrate may also function as a flavoring carrier. For example, the substrate may be impregnated with flavorings or tobacco extract. In some cases, the substrate may be non-magnetic.

[0123] In some cases, the support may be magnetic. This feature may be used to secure the support to an assembly during use or to generate a particular shape. In some cases, the aerosol-generating material may include one or more magnets that can be used to secure the material to an induction heater during use.

[0124] In some cases, the support may be substantially or completely impermeable to gases and / or aerosols. This prevents aerosols or gases from passing through the support layer, thereby controlling flow and ensuring delivery to the user. This can also be used, for example, to prevent condensation or other deposition of gases / aerosols on the surface of a heater provided in the aerosol generation assembly during use. This can therefore improve consumption efficiency and hygiene in some cases.

[0125] In some cases, the surface of the support that contacts the aerosol-generating material may be porous. For example, in one case, the support comprises paper. Porous supports such as paper have been found to be particularly suitable for the present invention. A porous (e.g., paper) layer contacts the aerosol-generating material and forms a strong bond. The aerosol-generating material is formed by drying a gel; without being limited by theory, it is believed that the gel-forming slurry partially penetrates the porous support (e.g., paper), resulting in partial bonding of the support to the gel as the gel solidifies and forms bridges. This provides a strong bond between the gel and the support (and between the dried gel and the support).

[0126] In one particular case, the support may be a paper-backed foil, with the paper layer abutting the aerosol-generating material, thereby providing the properties discussed in the previous paragraph. The foil backing is substantially impermeable and controls the flow path of the aerosol. The metal foil backing also serves to conduct heat to the aerosol-generating material.

[0127] In other cases, a layer of paper-backed foil abuts the aerosol-generating material, and the foil is substantially impermeable to prevent water provided to the aerosol-generating material from being absorbed by the paper, which could weaken its structural integrity.

[0128] In some cases, the support is formed from or includes a metal foil, such as aluminum foil. Metal supports can provide better conduction of thermal energy. Additionally or alternatively, the metal foil can function as a susceptor in an induction heating system. In certain embodiments, the support comprises a metal foil layer and a support layer, such as cardboard. In these embodiments, the thickness of the metal foil layer can be less than about 20 μm, such as from about 1 μm to about 10 μm, with a thickness of about 5 μm being preferred.

[0129] In some cases, the thickness of the support may be from about 0.010 mm to about 2.0 mm, with from about 0.015 mm, 0.02 mm, 0.05 mm, or 0.1 mm to about 1.5 mm, 1.0 mm, or 0.5 mm being preferred.

[0130] Further embodiments are contemplated in which a non-square inductor coil configuration is provided, it being understood that this refers to a single turn.

[0131] In particular, embodiments are contemplated in which more than two turns are provided, such that a two-layer or multi-layer construction is provided, according to which the majority of the construction comprises a type of PCB material.

[0132] It is also contemplated that the coil arrangement may comprise one or more loops.

[0133] While the above embodiments have, in some respects, focused on some particular exemplary aerosol generating systems, it will be appreciated that the same principles can be applied to aerosol generating systems using other technologies, i.e., the particular manner in which various aspects of the aerosol generating and delivering system function is not directly related to the underlying principles of the examples described herein.
