Description

[Technical field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of priority to European patent application EP21165276.3, filed March 26, 2021, the contents of which are incorporated herein by reference in their entirety for all purposes.

[0002] The present disclosure relates to aerosol-generating products, heating devices, and heating elements associated with heating aerosol-generating products. [Background technology]

[0003] The following discussion of the background art is intended to aid in the understanding of the present disclosure, but it should be understood that the discussion is not an admission or admission that any of the referenced material was published, publicly known, or part of the general common knowledge in any jurisdiction as of the priority date of this application.

[0004] Many heat-not-burn devices and associated heating elements have been proposed. A typical heat-not-burn device includes a heating device / element operable to heat an aerosol-generating product having an aerosol-generating substrate. The aerosol-generating product may include tobacco material and one or more filter elements. If the aerosol-generating product is replaced when the tobacco material is consumed, the filter included in the replaced device may be wasted.

[0005] In addition, current heating devices include a mouthpiece that can become heated, such that the heated mouthpiece can inadvertently burn the user's lips when the user first consumes the generated aerosol (i.e., the "first puff"). Furthermore, the thermal profile for heating the aerosol-generating product may not be optimized for a good taste profile for user enjoyment.

[0006] There is a need to develop a heating device, heating element, and / or aerosol generating product that at least partially ameliorates the above-mentioned shortcomings. Summary of the Invention [Means for solving the problem]

[0007] According to one aspect of the present disclosure there is provided a heating device as defined in claims 1 to 9. According to another aspect of the present disclosure there is provided an aerosol-generating product as defined in claims 10 to 14. According to another aspect of the present disclosure there is provided two-segment and three-segment products with an aerosol-generating substrate as defined in claims 15 to 21.

[0008] It is contemplated that the various embodiments may be combined in at least one manner, for example, in the form of a kit including an aerosol-generating product as described, and in the form of a heating device suitable for heating the aerosol-generating product as described.

[0009] Other aspects of the present disclosure will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments of the present disclosure in conjunction with the accompanying figures.

[0025] According to an embodiment, and with reference to Figure 1a, there is an aerosol-generating product 100 adapted for use with a non-combustion device. Figure 1a(i) shows a perspective view of the product 100, Figure 1a(ii) shows a side view of the product 100 as viewed from direction A, Figure 1a(iii) shows a side view of the product 100 as viewed from direction B, and Figure 1a(iv) shows a cross-sectional view of the product 100 as viewed from direction B.

[0026] The aerosol-generating product 100 can be directly inserted into a non-combustion device (e.g., the non-combustion devices shown in Figures 2a-2k). The aerosol-generating product 100 can include at least one aerosol-generating substrate 104 that forms a core layer 102 of the product 100. An outer layer 106 in the form of a cover or wrapper can be disposed to at least partially surround and provide structural integrity to the core layer 102. The at least one aerosol-generating substrate 104 includes at least one of reconstituted tobacco sheet, cast leaf tobacco sheet, tobacco powder, cut tobacco roll, acetate tow, natural fibers, natural leaves, cellulose fibers, tobacco pellets, and derivatives thereof.

[0027] The outer cover 106 can be formed from acetate tow, fiber (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper).

[0028] The embodiment shown in FIG. 1a includes at least one intermediate layer 108 disposed between the outer layer 106 and the aerosol-generating substrate 104, the intermediate layer 108 comprising one or more of the following materials: metal (including aluminum copper in foil / sheet form or other form), alloy, reconstituted tobacco sheet, paper (including coated paper), plastic (including PLA, polypropylene, e.g., biaxially oriented polypropylene or BOPP, etc.), polymer, fiber (including natural fiber), and ceramic. It is contemplated that additional intermediate layers 108 may be further disposed between the outer layer 106 and the aerosol-generating substrate 104, with each intermediate layer 108 being formed from a different material than the other intermediate layers 108. The aerosol-generating substrate 104 may include at least one of a tobacco material and a non-tobacco material. Also, the core layer may be single layered or multi-layered.

[0029] Another embodiment of an aerosol-generating product 100 is shown in Figures 1b and 1b-1, where like numerals refer to like parts.

[0030] FIG. 1b(i) shows an oblique view of product 100, FIG. 1b(ii) shows a side view of product 100 as viewed from direction A, FIG. 1b(iii) shows a side view of product 100 as viewed from direction B, and FIG. 1b(iv) shows a cross-sectional view of product 100 as viewed from direction B.

[0031] 1a, the core layer 102 is not completely or substantially filled by the aerosol-generating substrate 104, and further comprises a hollow portion 110 disposed adjacent the aerosol-generating substrate 104. In addition, an additional intermediate layer 112 is present, which may be thicker compared to the intermediate layer 108 disposed above the aerosol-generating substrate.

[0032] FIG. 1b-1(v) is an alternative to FIG. 1b(iii) and shows a side view of product 100 as viewed from direction B. FIG. 1b-1(vi) is an alternative to FIG. 1b(iv) and shows a cross-sectional view of product 100 as viewed from direction B. The hollow portion 110 shown in FIG. 1b-1(v) and FIG. 1b-1(vi) does not have an intermediate layer 112.

[0033] Another embodiment of the aerosol-generating product 100 is shown in FIG. 1c, where like numerals refer to like parts. The embodiment shown in FIG. 1c does not include a wrapping of the outer layer 106. Instead, the middle layer 108 is the outer layer, which includes at least one of metals (including aluminum copper in foil / sheet form or other forms), alloys, reconstituted tobacco sheets, paper (including coated paper), plastics (including PLA, polypropylene, e.g., biaxially oriented polypropylene or BOPP, etc.), polymers, fibers (including natural fibers), and ceramics. In other words, in the embodiment shown in FIG. 1c, the layer 108 can form the outer layer if only one layer is present, or can form both the outer layer and the middle layer if two or more layers are present. For example, the outer layer can be formed from coated paper, and the middle layer can be formed from a metal alloy, such as an aluminum alloy.

[0034] Another embodiment of an aerosol-generating product 100 is shown in Figure 1d, where like numerals refer to like parts. The embodiment shown in Figure 1d includes a relatively thicker outer layer 106 and a relatively thinner aerosol-generating substrate layer 104. The embodiment of Figure 1d does not include intermediate layers 108 or 112.

[0035] FIG. 1d(i) shows an oblique view of product 100, FIG. 1d(ii) shows a side view of product 100 as viewed from direction A, FIG. 1d(iii) shows a side view of product 100 as viewed from direction B, and FIG. 1d(iv) shows a cross-sectional view of product 100 as viewed from direction B.

[0036] The core layer 102 of the embodiment of Figure 1d includes a through hollow 114. With the through hollow 114, the core layer 102 can be considered a core region / central area without any material or layers formed therein. An aerosol-generating substrate 104, in the form of a reconstituted tobacco sheet, is laminated onto the outer periphery / periphery of the core layer 102. An outer layer 106, in the form of acetate tow, fiber (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper), is laminated onto the reconstituted tobacco sheet.

[0037] Another embodiment of an aerosol-generating product 100 is shown in Figure 1e, where like numerals refer to like parts. The embodiment shown in Figure 1e includes an outer layer 106 without an intermediate layer 108 or 112.

[0039] The core layer 102 of the embodiment of Figure 1e includes a through hollow 114. The aerosol-generating substrate 104, in the form of tobacco powder, is dispersed throughout the outer layer 106. The outer layer 106 can include acetate tow, fiber (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper) as a base material, and the tobacco powder can be coated onto the acetate tow.

[0040] Another embodiment of an aerosol-generating product 100 is shown in Figure 1f, where like numerals refer to like parts. The embodiment shown in Figure 1f includes an outer layer 106 without an intermediate layer 108 or 112.

[0041] Figure 1f(i) shows an oblique view of product 100, Figure 1f(ii) shows a side view of product 100 as viewed from direction A, Figure 1f(iii) shows a side view of product 100 as viewed from direction B, and Figure 1f(iv) shows a cross-sectional view of product 100 as viewed from direction B.

[0042] The embodiment shown in Figure 1f does not have a hollow portion 114. In addition, there is a single core layer 102 that includes acetate tow as the base material. The aerosol-generating substrate 104, in the form of tobacco powder, is dispersed throughout the core layer 102.

[0043] Another embodiment of an aerosol-generating product 100 is shown in FIG. 1g, where like numerals refer to like parts.

[0044] FIG. 1g(i) shows a perspective view of the product 100, FIG. 1g(ii) shows a side view of the product 100 as viewed from direction A, FIG. 1g(iii) shows a side view of the product 100 as viewed from direction B, and FIG. 1g(iv) shows a cross-sectional view of the product 100 as viewed from direction B. The core layer 102 of the embodiment of FIG. 1g includes a through-hole 114. The aerosol-generating substrate 104, in the form of a reconstituted tobacco sheet, is laminated over the through-hole 114. The intermediate layer 108 is formed from acetate tow, fiber (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper). The outer layer 106 can be a single layer comprising paper, or can be multiple layers including materials such as metals (including aluminum copper in foil / sheet form or other forms), alloys, reconstituted tobacco sheets, papers (including coated papers), plastics (including PLA, polypropylene, e.g., biaxially oriented polypropylene or BOPP, etc.), polymers, fibers (including natural fibers), and ceramics.

[0045] Another embodiment of an aerosol-generating product 100 is shown in FIG. 1h, where like numerals refer to like parts.

[0046] FIG. 1h(i) shows an oblique view of product 100, FIG. 1h(ii) shows a side view of product 100 as viewed from direction A, FIG. 1h(iii) shows a side view of product 100 as viewed from direction B, and FIG. 1h(iv) shows a cross-sectional view of product 100 as viewed from direction B.

[0047] The core layer 102 of the embodiment of FIG. 1h includes a through hollow 114. The aerosol-generating substrate 104, in the form of tobacco powder, is dispersed on the intermediate layer 108. The intermediate layer 108 is formed from acetate tow, fiber (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper). The outer layer 106 can be a single layer with paper or can be multi-layered including materials such as metals (including aluminum copper in foil / sheet form or other forms), alloys, reconstituted tobacco sheets, paper (including coated paper), plastics (including PLA, polypropylene, e.g., biaxially oriented polypropylene or BOPP, etc.), polymers, fibers (including natural fibers), and ceramics.

[0048] Another embodiment of an aerosol-generating product 100 is shown in FIG. 1i, where like numerals refer to like parts.

[0049] FIG. 1i(i) shows an oblique view of product 100, FIG. 1i(ii) shows a side view of product 100 as viewed from direction A, FIG. 1i(iii) shows a side view of product 100 as viewed from direction B, and FIG. 1i(iv) shows a cross-sectional view of product 100 as viewed from direction B.

[0050] The core layer 102 of the embodiment of Figure 1i comprises acetate tow. The aerosol-generating substrate 104, in the form of tobacco powder, is dispersed over the core layer 102. The outer layer 106 can be a single layer comprising paper, or can be multi-layered including materials such as metals (including aluminum copper in foil / sheet form or other forms), alloys, reconstituted tobacco sheets, papers (including coated papers), plastics (including PLA, polypropylene, e.g., biaxially oriented polypropylene or BOPP, etc.), polymers, fibers (including natural fibers), and ceramics.

[0051] It can be appreciated that Figures 1h and 1i may not include tobacco powder, in which case the aerosol-forming substrate 104 may form part of the outer layer 106 or the intermediate layer 108.

[0052] Figures 1j and 1k show various forms of preform shapes. The aerosol-generating substrates are held together by a binder and compressed by pressure to form these shapes.

[0053] In the embodiment depicted in Figures 1a to 1k, one skilled in the art will recognize that acetate tow is contemplated for use as the outer layer 106, as the base material forming part of the core layer 102, and / or as the base material forming part of the intermediate layer 108.

[0054] In some embodiments, the outer layer 106 or wrapper comprises at least one layer of paper, metal, alloy, reconstituted tobacco sheet, cast leaf tobacco (CLT) sheet, acetate tow, heat stick wrapper plastic (including PLA, polypropylene, such as biaxially oriented polypropylene or BOPP), polymer, fiber (including natural fibers), and ceramic. When the wrapper is metal, the metal can include aluminum or copper in foil form.

[0055] In some embodiments, the aerosol-generating product is a cylindrical rod having a length in the range of 5 mm to 250 mm.

[0056] In some embodiments, a single segment includes a base ingredient having at least one of propylene glycol (PG) and vegetable glycerin (VG). When both PG and VG are present, their total amount is less than 20 milligrams. In some embodiments, the ratio of PG:VG is 1:1.

[0057] In some embodiments, the aerosol-generating product 100 can have an overall planar shape, i.e., can have a dimension (e.g., thickness, etc.) that is much smaller than other dimensions (e.g., length, width, etc.) In some embodiments, the planar shape is a prismatic or cylindrical shape.

[0058] The aerosol-generating product 100 can be cast, molded or shaped, formed by rolling, pressing, stamping, injection or extrusion, reconstitution, or a combination of one or more of the above, and any other process. The form of the aerosol-generating substrate 102 can be one of cut lugs, compacted to a predetermined shape, powder, dust, flakes, pellets, granules, tablets, pills, paper, blocks, porous blocks, sheets, nets, fibers, fibers woven into sheets, slices, ribbons, or combinations thereof. The aerosol-generating product 100 can be designed for products made from loose tobacco / flavored non-tobacco and rolling papers (such as, but not limited to, roll your own (RYO) products) or other heated devices. The aerosol-generating product 100 can be configured in the form of a capsule.

[0059] It can be seen that the embodiment depicted in Figures 1a to 1j is a single segment aerosol generating product. Such a single segment is advantageously compact and can be used with the heating device 200.

[0060] According to another embodiment, and as shown in Figure 2 (Figures 2a to 2k), there is a heating device 200 suitable for heating an aerosol-generating substrate or product. The heating device 200 includes an inhalation portion 202 in the form of a mouthpiece / nosepiece 202 that allows a user to consume an aerosol generated by the aerosol-generating substrate; a substrate holder 204 for receiving the aerosol-generating substrate; a heating element 206 that is shaped and dimensioned to heat the aerosol-generating substrate to create an aerosol; and an aerosol delivery channel 208 positioned to receive the aerosol generated from heating the aerosol-generating substrate and direct the aerosol towards the mouthpiece / nosepiece 202.

[0061] The heating device 200 can be powered using a battery 214 contained within the heating device 200. The battery 214 can be a Lithium-ion Polymer (LiPo) battery. A charging port 216 can be provided within the device 200 for charging the LiPo battery. The charging port 216 can be a USB-type charging port or other known charging ports (including wireless charging ports). The battery 214 can be electrically connected to the heating element 206 and is adapted to raise the temperature of the heating element 206 to a desired temperature or temperature profile.

[0062] Due to the heat generation of the heating element 206, a heat sink area or region can be provided within the device 200. The heat sink area can include one or more metal or alloy coatings, plates, and / or holders 240 positioned in a manner to reduce heat within the device 200.

[0063] In some embodiments, a heat sink in the form of a fin-like structure can be located in the area proximate to the mouthpiece / nosepiece 202. The heat sink can be formed from manufacturing methods such as, but not limited to, extrusion, die casting, machining processes, 3D printing, investment casting, and injection molding.

[0064] It may include an insulating region in the form of one or more walls 209 surrounding the substrate holder 204 to insulate heat generated from the substrate holder 204 to minimize and prevent heat transfer to the surface of the device 200. The insulating walls 209 may be positioned adjacent to the heat sink 207 to dissipate heat away from the substrate holder 204 and insulate heat from the surface of the device 200.

[0065] With reference to the embodiment shown in FIG. 2a, the device 200 may include a fixture 250 as an alternative to the substrate holder 204 for receiving the aerosol-generating product and / or at least one filter unit. The aerosol-generating product may be a single-segment aerosol-generating product 100. The fixture 250 may include or accommodate a metal hollow or cup-shaped cylinder 207 for holding the aerosol-generating product, the cylinder 207 being made of aluminum, copper, magnesium, stainless steel, or other conductive material such that it is capable of dissipating heat away from the generated aerosol. The fixture 250 may be adjustable relative to the length of the aerosol-generating product to facilitate insertion and removal of the aerosol-generating product from the substrate holder 204. The fixture may include a filter holder 210 for receiving at least one filter 212, which is positioned proximate to the mouthpiece 202 in such a manner as to filter particulates from the generated aerosol prior to consumption by the user. The heating element 206 can have a sliding mechanism 213 such that the heating element 206 can be adjusted to move up and down to heat aerosol-generating products of different lengths. The sliding mechanism 213 can have a biasing mechanism as known to those skilled in the art to bias the element 206 in different positions to accommodate different aerosol-generating products.

[0066] In the embodiment of Figure 2a, the portion of the device 200 that receives the fixture may be lined with insulation 244 (see Figure 2a(iii)) in the form of materials such as plastic, metal, fiber, glass, ceramic, carbon, aerogel, etc., to insulate against heat generated by the heating element 206. Alternatively, the insulation 244 may include a vacuum chamber surrounding the heating element and / or fixture 250.

[0067] It can be appreciated that the base of the fixture can include a slot or hole for insertion of a thermal element to contact the aerosol-generating product 100. When inserted, the aerosol-generating product 100 is clamped between the fixture 250 and the receiving portion 246 to prevent air from escaping. The receiving portion 246 can include two or more biasing mechanisms such that a force is exerted on the fixture 250 when it is inserted to hold it securely within the device 200. During operation, air can enter the device 200 through any air gaps 224 formed around the fixture 250.

[0068] Referring to FIG. 2b, FIG. 2b shows another embodiment of the device 200 including two parts 200a and 200b. The first part 200a, which may be referred to as the device cap, houses the aerosol delivery channel 208, the filter holder 210 (with filter 212, when present), and the substrate holder 204 (with substrate 205, when present). The second part 200b, which may be referred to as the device body, houses the battery 214, the charging port 216, an optional pin reset / actuator 218 for operating the device 218, and the heat sink 240. In the embodiment shown in FIG. 2b, the aerosol delivery channel 208 is a U-shaped channel arranged to connect an air pocket 220 (also referred to as an airflow pocket) located adjacent to the substrate holder 204 to the filter holder 210. FIG. 2 c is a cross-sectional view showing the device of FIG. 2 b in operation, with the aerosol-generating substrate 205 in contact with the heating element 206 and the filter 212 held in place by the filter holder 210 .

[0069] When parts 200a and 200b are connected and device 200 is operated through the use of actuator 218, heating element 206 heats up to a desired temperature. As a result, substrate 205 and the air surrounding the substrate in air pocket 220 are heated. Air from outside device 200 is drawn into the device around one or more air gaps / inlets 224 defined at the interface between parts 200a, 200b towards substrate 205. Air flowing towards substrate 205 can be simultaneously heated with substrate 205 and then flow through heat sink 240, thereby reducing the temperature of the air. Air drawn into substrate 205 carries aerosol generated by heating substrate 205 towards air pocket 220 and then to U-shaped aerosol delivery channel 208. The aerosol delivery channel 208 can be coated with a layer of metal, such as aluminum, copper, magnesium, stainless steel, or other conductive material (which effectively forms a heat sink) to extract heat away from the aerosol flowing through the aerosol delivery channel 208 before it enters the mouthpiece 202. A heat sink 240 (positioned adjacent the aerosol delivery channel 208) further aids in dissipating heat away from the aerosol delivery channel 208.

[0070] FIG. 2d shows another embodiment of the device 200. Instead of the two-part configuration shown in FIG. 2b and FIG. 2c, the part 200a can further include parts 200a1 and 200a2. Such an arrangement conveniently provides a cover for easy replacement of the filter 212. The part 200a1 can be referred to as the device cover, and the part 200a2 can be referred to as the device cap. In conjunction, the parts 200a1 and 200a2 house the aerosol delivery channel 208, the filter holder 210 (with the filter 212, if present), the substrate holder 204 (with the substrate 205, if present). The second part 200b can be referred to as the device body, and houses the battery 214, the charging port 216, any pin actuators 218 for operating the device (including actuators for reset, on / off, operation control), and the heat sink 240. In the embodiment shown in FIG. 2d, the aerosol delivery channel 208 can be a straight channel, similar to the air pockets 220 located adjacent to the substrate holder 204 and to the filter holder 210. A single piece of heat sink 240 comprising one or more metals (e.g., aluminum, copper, magnesium, stainless steel, or other conductive material, etc.) can be positioned proximate or adjacent to the aerosol delivery channel 208 and the substrate holder 204 to aid in dissipating heat away from the aerosol delivery channel 208. In the embodiment shown in FIG. 2d, the mouthpiece 202 can be coated with a layer of metal (e.g., aluminum, copper, magnesium, stainless steel, or other conductive material, etc., which effectively forms a heat sink) to extract heat from the aerosol flowing through the mouthpiece 202.

[0071] FIG. 2e is a cross-sectional view showing the device of FIG. 2d in operation, with the aerosol-generating substrate 205 in contact with the heating element 206 and the filter 212 held in place by the filter holder 210.

[0072] When parts 200a and 200b are connected and device 200 is operated through the use of actuator 218, heating element 206 heats to a desired temperature. As a result, substrate 205 and the air surrounding the substrate in aerosol delivery channel 208 (air pocket 220) are heated. Air from outside device 200 is drawn into the device toward substrate 205 around one or more air gaps / inlets 224 defined at the interface between parts 200a, 200b. Air flowing toward substrate 205 (which may be heated at the same time) can flow through heat sink 240, thereby reducing the temperature of the air. Air drawn into substrate 205 carries aerosol generated by heating substrate 205 toward air pocket 220 and then to aerosol delivery channel 208 adjacent to substrate holder 204. A heat sink 240 , positioned adjacent to the aerosol delivery channel 208 , further aids in dissipating heat away from the aerosol delivery channel 208 .

[0073] FIG. 2f is another embodiment of the device 200. Instead of a U-shaped aerosol delivery channel or a straight delivery channel 208, the aerosol delivery channel shown in FIG. 2f is Z-shaped. Also, the embodiment of FIG. 2f shows part 200a housing only the substrate holder 204, with other components housed by part 200b. The substrate holder 204 can be shaped and dimensioned as a hollow tube for receiving a corresponding substrate 205 therein. Mechanical gaskets (e.g., O-rings 260, etc.) can be positioned at various joints to promote proper airflow within the device 200. A cup-like or cylinder structure 207 can line the substrate holder 204 for receiving the substrate 205.

[0074] FIG. 2g is a cross-sectional view showing the device of FIG. 2f in operation, with the aerosol-generating substrate 205 in contact with the heating element 206 and the filter 212 held in place by the filter holder 210.

[0075] When parts 200a and 200b are connected and device 200 is operated through the use of actuator 218, heating element 206 heats to a desired temperature. As a result, substrate 205 and the air surrounding the substrate in aerosol delivery channel 208 (air pocket 220) are heated. Air from outside device 200 is drawn into the device around one or more air gaps / inlets 224 defined at the interface between parts 200a, 200b toward substrate 205. The air drawn into substrate 205 carries aerosol generated by heating substrate 205 toward air pocket 220, which forms part of aerosol delivery channel 208 adjacent substrate holder 204. A layer of metal is coated on a portion of aerosol delivery channel 208 to facilitate heat transfer. One or more heat sinks 240 , positioned adjacent the aerosol delivery channel 208 , further aid in dissipating heat away from the aerosol delivery channel 208 .

[0076] It is contemplated that various features of the embodiments shown in Figures 2b, 2d, and 2f may be combined. As a non-limiting example, the aerosol delivery channel 208 and the mouthpiece 202 of each embodiment may both be coated with a conductive material to form further embodiments. As another example, an O-ring 260 or other suitable gasket may be positioned within the device 200 as shown in Figures 2b and 2d.

[0077] In the embodiment shown in Figures 2a through 2k, the coating on the aerosol delivery channel and / or mouthpiece can be considered a first thermal conductor, and the metal plate proximate to the aerosol delivery channel can be considered a second thermal conductor operable to dissipate heat away from the first thermal conductor.

[0078] Figure 2h shows an embodiment having a similar exterior profile to the device shown in Figure 2d. The device cover 200a1 is rotatable relative to the device cap 200a2 to allow for removably detaching the device cover 200a1 from the device cap 200a2. The device cap 200a2 includes a slot for receiving the fixture 250, except that in the embodiment shown in Figure 2h, the mouthpiece 202 is not part of the fixture 250. The compartment of the fixture 250 for receiving the aerosol-generating substrate can be lined / coated with a suitable thermally conductive material.

[0079] 2i illustrates an embodiment of a fixture 250, where the part of the fixture 250 that receives the aerosol-generating substrate allows excess material to be forced out of the substrate during use. Suitable openings / gaps are formed on the fixture 250 to allow excess material to be forced out of the fixture 250.

[0080] Figure 2j illustrates another embodiment suitable for use with the various embodiments in Figures 2a-2i, where a heat sink in the form of a fin-like structure can be positioned in the area proximate to the mouthpiece / nosepiece 202. The heat sink can be formed from manufacturing methods such as, but not limited to, extrusion, die casting, machining processes, 3D printing, investment casting, and injection molding.

[0081] 2k illustrates an embodiment in which the area / walls surrounding the heating element 206 may be coated / laminated with a metal (such as, for example, aluminum, copper, stainless steel, or alloy 252) in the form of fibers, strips, sheets, chips, powder, or granules. The outer surface of the device 200 (i.e., the surface in direct contact with the environment) may be formed from a metal or alloy (such as, for example, an aluminum alloy) or a plastic.

[0082] 2l and 2l-1 show another embodiment of device 200 that includes a through-hole or bore portion 270 extending across device 200, which includes both an aerosol delivery channel 208 and a substrate holder 204, and a first end 270a of through-hole portion 270 that is dimensioned to slidably receive suction portion 202, aerosol-generating substrate 205, and / or filter unit 212.

[0083] In the embodiment shown in Figures 2l and 2l-1, the heating element 206 can be a cylindrical hollow surrounding a portion of the through-hole portion 270. As seen from the cross-sectional view, there is a cross-sectional side 206a and a second cross-sectional side 206b that are configured to conduct heat through the through-hole portion 270 to heat the aerosol-generating substrate 205 when the aerosol-generating substrate 205 is positioned within the through-hole portion 270 and in a position corresponding to the hollow portion of the cylindrical hollow. From the cross-sectional view, the aerosol-generating substrate 205 is positioned between the cross-sectional side 206a and the second cross-sectional side 206b.

[0084] It is contemplated that a user may insert the aerosol-generating substrate 205 through the first end 270a of the through-hole portion 270. The suction portion 202 may be shaped and dimensioned to urge the aerosol-generating substrate 205 towards a position between the first cross-sectional side 206a and the second cross-sectional side 206b.

[0085] The through hole portion 270 can be dimensioned to receive the filter unit 500, which is positioned during operation such that the heated aerosol is directed through the filter unit 500 before reaching the suction portion 202.

[0086] The through-hole portion 270 includes a second end 270b for urging at least one of the aerosol-generating substrate 205 and the filter unit 500 out of the through-hole portion 270 after consumption.

[0087] As an alternative or in addition to the various heat sink configurations as described, one or more temperature sensors can be positioned in the device 200 to provide feedback on the aerosol temperature. The feedback can then be sent to a controller (not shown) for providing temperature control according to one or more heating profiles (see FIGS. 4a-4e). The controller can be in the form of an integrated circuit chip (IC) (such as, but not limited to, an application specific integrated circuit (ASIC) chip). Such an arrangement can advantageously facilitate dynamic control by the controller of the heating profile of the heating element 206 to optimize energy power consumption.

[0088] It can be appreciated that the device 200 works on the principle of separating the aerosol-generating substrate (e.g. tobacco) from the filter. This is particularly suited to single segment embodiments of the aerosol-generating product 100. For aerosol-generating products 100 having a segment that includes a filter, the additional filter 212 may not be required in operation and the slot 210 may be left empty.

[0089] In some embodiments, the aerosol delivery channel 208 and / or the mouthpiece can be coated with a heat dissipating material or heat sink. Suitable materials can be metals or alloys (e.g., aluminum alloys, magnesium, stainless steel, or other conductive materials, etc.) to extract heat away from the mouthpiece 202.

[0090] 3a-3c show various embodiments of a heating element for use with a heating device (such as, but not limited to, heating device 200) for heating at least one aerosol-generating substrate (such as, but not limited to, aerosol-generating substrate 102) without combustion of the at least one aerosol-generating substrate, where the heater element 302 is shaped and dimensioned to be in thermal contact with at least one aerosol-generating product. FIG. 3d shows various embodiments in which at least one heating pin 314 is positioned adjacent to the heater element 302 to provide homogenous temperature control within the aerosol-generating product, where the at least one heating pin 314 is formed from metal, alloy, ceramic, nickel-plated, and silver, or other composite material with or without a coating. The heating pin 314 can be shaped and dimensioned to have a substantially thinner width compared to the heater element 302.

[0091] The heating element can include an elongated body portion, a first end 304 adapted to receive electrical power, and a second end adapted to provide optimal contact with the aerosol-generating substrate.

[0092] In some embodiments, the second end 306 of the heating element includes a rounded or tapered tip. The tapered tip 306 can be a frusto-conical tip or can include one or more chamfered surfaces or a circular cross-section with at least two recessed portions. The interior of the tip 306 can be hollow or partially hollow. The interior of the elongated body portion can be hollow or partially hollow.

[0093] In some embodiments, the elongated body portion of the heating element has at least one of an L-shaped cross-section, a V-shaped cross-section, a Φ-shaped cross-section, a C-shaped cross-section, a J-shaped cross-section, an X-shaped cross-section, a Y-shaped cross-section, a T-shaped cross-section, a triangular cross-section, or a rectangular cross-section.

[0094] In some embodiments of the heating element, the heating element has a coin-shaped or planar shape 308. In other embodiments, the heating element has a cylindrical profile 310, with the inner surface of the cylinder in thermal contact with the aerosol-generating product 102. In some embodiments, heating can be achieved by an inductor or inductor element. In some embodiments, the heating element has a tube profile 320, which can be seen to be similar in shape to the cylindrical profile 310 with the base portion removed to form a through bore.

[0095] In some embodiments of the heating element, the body portion is formed from aluminum, while in other embodiments the body portion can be formed from other materials such as glass / fiberglass, etc.

[0096] The heating elements shown in Figures 3a to 3c are in the form of elongated tubes and may be hollow to receive electrical circuitry or a substrate, although it can be appreciated that other shapes and sizes may be contemplated to receive aerosol-generating substrates of different shapes and sizes.

[0097] According to another aspect of the disclosure, there is a controller for use with a heating device (such as, for example, heating device 200 as illustrated in FIGS. 2a-2k). The controller can include sensors for sensing the temperature and / or pressure of a heating element of the heating device. Alternatively, the heating device can include one or more of the sensors.

[0098] The pressure sensor can be configured to sense a pressure corresponding to a suction force exerted on a mouthpiece of the heating device, which in turn can correspond to a user consuming the aerosol through his or her mouth (i.e., taking a "puff"). To heat the heating element, an electrical circuit can be arranged to either send a current directly to the heating element or induce a current to flow through the heating element.

[0099] It is contemplated that during operation, the controller can be configured to increase the temperature from room temperature to achieve a first quiescent temperature and a first operating temperature, the first operating temperature being related to the suction force detected by the pressure sensor.

[0100] Figures 4a to 4e show five heating profiles corresponding to different quiescent and operating temperatures.

[0101] FIG. 4a shows a controller programmed to provide a first heating profile. The first heating profile includes a first resting temperature between 200 degrees Celsius (°C) and 400°C, and a first operating temperature above 200°C and up to 400°C. In operation, the heating element is heated from room / ambient temperature to the first resting temperature. When pressure detects that suction is applied to the mouthpiece 202, the controller operates to heat the heating element up to an operating temperature of 400°C. When suction is no longer applied, the temperature of the heating element drops back to the first resting temperature. This process is repeated until reset or until the aerosol-generating substrate is consumed. In the embodiment shown in FIG. 4a, the first resting temperature can be in the range of 300°C to 350°C.

[0102] FIG. 4b shows the controller programmed to provide a second heating profile. The second heating profile includes a first rest temperature in the temperature range of 250° C. to 400° C., a first operating temperature at a temperature lower than the first rest temperature and in the range of 200° C. to 350° C., and a second rest temperature above the first operating temperature, the second rest temperature being below the first rest temperature. In operation, the heating element is heated from room / ambient temperature to the first rest temperature. When the pressure sensor detects that suction is being applied to the mouthpiece 202, the controller operates to cool the heating element to an operating temperature of approximately 200° C. When suction is no longer being applied, the temperature of the heating element rises to the first rest temperature. However, after a predetermined number of “puffs” are taken by the user, the temperature of the heating element is maintained at the second rest temperature, regardless of whether any subsequent suction is detected by the pressure sensor. The predetermined number of "puffs" may be three puffs, and the second rest temperature may be a temperature below the first rest temperature but above the first operating temperature.

[0103] FIG. 4c shows the controller programmed to provide a third heating profile. The third heating profile includes a first rest temperature in the range of 200 degrees Celsius (°C) to 400°C, a second rest temperature below the first rest temperature and above 200°C, a first operating temperature below the first rest temperature and at least 200°C, and a second operating temperature above the second rest temperature and up to 400°C. In operation, the heating element is heated from room / ambient temperature to the first rest temperature. When a pressure sensor detects that suction is being applied to the mouthpiece 202, the controller operates to cool the heating element to an operating temperature of approximately 200°C. When suction is no longer being applied, the temperature of the heating element rises to the first rest temperature. However, after a predetermined number of "puffs" (e.g., three) are taken by the user, the temperature of the heating element drops to the second rest temperature. When the user takes a further / subsequent puff, the controller operates to heat the heating element up to an operating temperature of 400° C., with the second rest temperature being below the first rest temperature but above the first operating temperature. It may be appreciated that the third heating profile may be considered a combination of the second heating profile and the first heating profile.

[0104] FIG. 4d illustrates a controller programmed to provide a fourth heating profile. The fourth heating profile can include a first resting temperature in the range of 200 degrees Celsius (°C) to 400°C, a first operating temperature above the first resting temperature up to 400°C, and a second operating temperature above 200°C and below the first resting temperature. In operation, the heating element is heated from room / ambient temperature to the first resting temperature. When a pressure sensor detects that suction is being applied to the mouthpiece 202, the controller operates to raise the heating element to an operating temperature of approximately 400°C. When suction is no longer being applied, the temperature of the heating element drops to the first resting temperature. However, after a predetermined number of "puffs" (e.g., three) are taken by the user, subsequent puffs result in a drop in the temperature of the heating element below the first resting temperature, and release of suction results in an increase in temperature to the first resting temperature. It may be appreciated that the fourth heating profile may be considered a combination of the first heating profile and the second heating profile.

[0105] 4e illustrates the controller programmed to provide a fifth heating profile. The fifth heating profile can include a first resting temperature ranging from 200 degrees Celsius (°C) to 400°C and a first operating temperature above the first resting temperature up to 400°C. In operation, the heating element is heated from room / ambient temperature to the first resting temperature. When pressure detects that suction force is being applied to the mouthpiece 202, the controller operates to raise the heating element to an operating temperature of approximately 400°C. When suction force is no longer being applied, the temperature of the heating element is maintained at the operating temperature.

[0106] It can be appreciated that the temperatures of 200° C. and / or 400° C. are optional. Other quiescent and operating temperatures having profiles similar to one of the five heating profiles as described can be contemplated.

[0107] It can be appreciated that in some embodiments, the controller can control the heating profile of the heating element by logic instructions or software programs preloaded into the controller. In some embodiments, the controller can dynamically control the heating profile of the heating element based on input and feedback from temperature and pressure sensors installed in the heating device (e.g., device 200) to track the actual temperature and pressure of the aerosol.

[0108] It can be appreciated that one or more of the various heating profiles can be combined and preloaded into the controller to the extent that they are not inconsistent during operation.

[0109] FIG. 5a shows a filter unit 500 suitable for use with the heating device described in the previous embodiment. The filter unit 500 includes a core layer 502, an outer layer 504, and an intermediate layer 506 sandwiched between the core layer 502 and the outer layer 504. In the embodiment shown in FIG. 5a, the core layer 502 and the outer layer 504 are formed of materials including acetate tow, fibers (including synthetic and natural fibers), cotton, fabric, mesh, and / or paper (including coated paper). The intermediate layer 506 can be a single layer with paper, or it can be a multi-layer structure including materials such as metals (including aluminum copper in foil / sheet form or other forms), alloys, reconstituted tobacco sheets, paper (including coated paper), plastics (including PLA and BOPP), polymers, fibers (including natural fibers), and ceramics. The filter unit 500 can be shaped and sized as a rod. It can be appreciated that the various layers can be arranged coaxially with respect to each other.

[0110] FIG. 5b shows a variation of FIG. 5a in which the core layer 502 is partially hollowed out and defines a hollow portion 510. It further includes another intermediate layer 512 disposed between the core layer 502 and the intermediate layer 506. It should be appreciated that the intermediate layer 512 may or may not extend to the hollow portion 510. FIG. 5c illustrates another variation of FIG. 5a in which the core layer 502 is partially hollowed out and defines a hollow portion 510. Unlike the embodiment shown in FIG. 5b, the embodiment shown in FIG. 5c does not have an intermediate layer 512.

[0111] FIG. 6 (FIGS. 6a to 6f) relates to a substrate holder 600 (also referred to as a fixture) for using one or more of the heating devices 200 (particularly the embodiment shown in FIG. 2a).

[0112] The substrate holder 600 can be configured to hold one or more different single segment aerosol-generating products, including those shown in Figures la through lk, one or more two segment aerosol-generating products, including those shown in Figures 7a through 7l, one or more three segment aerosol-generating products, including those shown in Figures 8a through 8n, and / or one or more filter segments, including those shown in Figures 5a, 5b, and 5c. The substrate holder 600 includes a mouthpiece 602, an elongated structure 604 including multiple compartments 606, and an end portion 608 disposed distally relative to the mouthpiece 602.

[0113] FIG. 6a shows a substrate holder 600 having a first compartment 610 located proximate the distal end portion 608 and one or more second compartments 612 adjacent the mouthpiece 602. The first compartment 610 is shaped and dimensioned to receive a single-segment aerosol-generating product, including those shown in any one of FIGS. 1a-1k, a two-segment aerosol-generating product, including those shown in FIGS. 7a-7l, or a three-segment aerosol-generating product, including those shown in FIGS. 8a-8n. The end portion 608 is formed with a through hole portion such that, in operation, a heating element of the heating device 200 can contact the single-segment aerosol-generating product 100 and generate aerosol therefrom. The first compartment 610 can be coated or mounted with one or more thermal conductors 614. The one or more thermal conductors 614 can be shaped and dimensioned to be inserted into the first compartment 610 without interfering with the ability of the first compartment 610 to accept a single segment aerosol generating product.

[0114] The one or more second compartments 612 are shaped and dimensioned to receive a filter unit, including those shown in Figures 5a, 5b, and 5c, and / or a heat dissipation tube 618. The heat dissipation tube 618 can be an aluminum tube. If there are multiple second compartments 612 and the heat dissipation tube 618 is installed in one of the multiple second compartments 612, the filter unit will have to be installed in another of the multiple second compartments 612.

[0115] Between the first compartment 610 and the second compartment 612 are one or more third compartments 616. The third compartments 616 function as a connection between the first compartment 610 and the second compartment 612 and typically can be formed from less material compared to the first compartment 610 and the second compartment 612. This is because the third compartment 616 does not receive an aerosol-generating product or a filter unit. Less material associated with the third compartment 616 advantageously reduces heat transfer to the second compartment 612.

[0116] In the embodiment shown in FIG. 6 a , it includes one first compartment 610 , two second compartments 612 , and one third compartment 616 .

[0117] Figure 6b shows another embodiment of the fixture with one first component 610 and three second compartments 612. In the embodiment of Figure 6b, the third compartment 616 is absent. At least one of the three second compartments 612 serves as a connector between the first compartment 610 and the other second compartments 612.

[0118] It should be appreciated that there can be four or more second compartments 612. In some embodiments, one or more of the second compartments 612 can be enclosed or covered. A covered or enclosed second compartment 612 can contain an aluminum tube 618.

[0119] 6c through 6f show various embodiments of the fixture 600 with different configurations / positioning of the aluminum tube 618 or other thermally conductive metal or metal alloy, the aerosol-generating substrate, and the filter unit.
