[0120] The material may be present on or within the support to form a matrix. The support may be, or include, for example, paper, cardboard, paperboard, reconstituted materials, plastic materials, ceramic materials, composite materials, glass, metal, or metal alloy.

[0121] An aerosol supply device can receive an article comprising aerosol-generating material for heating. As used herein, an "article" is a component that includes or contains aerosol-generating material in use, is heated to atomize the aerosol-generating material, and optionally includes or has other components in use. A user can insert the article into or onto an aerosol supply device and then heat the article to generate an aerosol, which the user subsequently inhales.

[0122] An aerosol generator is a device configured to generate aerosols from aerosol-generating materials. In some embodiments, an aerosol generator is a heater configured to subject aerosol-generating materials to thermal energy, causing the aerosol-generating materials to release one or more volatiles to form an aerosol.

[0123] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transport component, an aerosol transport component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may include a conductor capable of being heated by an electric current flowing through it.

[0124] Non-combustible aerosol supply systems may include modular components comprising both a reusable aerosol supply device and a replaceable aerosol generating article. In some implementations, the non-combustible aerosol supply device may include a power source and a controller (or control circuitry). The power source may include, for example, a power source such as a battery or rechargeable battery. In some implementations, the non-combustible aerosol supply device may also include an aerosol generating component. However, in other implementations, the aerosol generating article may partially or completely comprise the aerosol generating component.

[0125] Figure 1 A schematic diagram of an aerosol supply system 100 is shown. The aerosol supply system 100 includes an aerosol supply device 200 and an article 300, which includes an aerosol generating material 302 (see reference). Figure 3 ). 300 products in Figure 2 The image shows the product being removed from the aerosol supply device 200. The aerosol generator 304 of the article 300 is... Figure 3 The first side 306 is shown in a perspective view, and in Figure 4 A perspective view of a portion of the second side 307 is shown in the middle.

[0126] Article 300 includes an aerosol generator 304. The aerosol generator 304 is configured to generate aerosols from the aerosol generating material 302 during operation of the aerosol supply system 100, as will be described in detail below.

[0127] The aerosol supply system 100 may be elongated and extend along a longitudinal axis. The aerosol supply system 100 has a proximal end 102 that is closest to the user (e.g., closest to the user's mouth) when the user inhales the aerosol generated by the aerosol supply system 100, and a distal end 104 that is furthest from the user during use.

[0128] The proximal end can also be referred to as the "mouth end". Therefore, the aerosol supply system 100 is defined in a proximal direction toward the user during use. In addition, the aerosol supply system 100 is also defined in a distal direction away from the user during use. The terms "proximal" and "distal" when applied to features of the system 100 will be described by referring to the relative positioning of these features with respect to each other in the proximal-distal direction along the longitudinal axis.

[0129] Article 300 is received by aerosol supply device 200. The configurations of article 300 and aerosol supply device 200 can vary. In this embodiment, aerosol supply device 200 includes a device body 202. Device 200 has a housing 204 surrounding the various components of the device. Figure 5 As shown, a product receiving portion 206 (sometimes referred to as device chamber 206) is configured to receive a portion of a product 300. When the product 300 is received in the device chamber 206, the proximal end 308 of the product extends from the device 200. The receiving portion 208 defines the chamber 206. The receiving portion 208 includes a receiving portion bottom 210 and a receiving portion outer peripheral wall 212. The configuration of the receiving portion 208 can vary depending on the configuration of the product 300.

[0130] One or more user-operable control elements 224, such as buttons or switches, can be provided on the aerosol supply device 200 for operating the aerosol supply system 100. For example, a user can start the system 100 by pressing the control element 224. One or more user-operable control elements may be omitted. In some embodiments, the aerosol supply system 100 is operated by other user actions, such as "intake" initiated by a user drawing air through the system.

[0131] The aerosol supply device 200 includes an opening 214 at a proximal end that leads into a device chamber 206. The opening 214 is disposed at one end through which an article 300 can be inserted. In some embodiments, the article 300 can be fully or partially inserted into the device 200. The configuration of the device 200 can vary; for example, the opening may be located in a longitudinal sidewall of the device 200, and / or the opening may be closed during use by another feature of the device 200. In the configuration of the invention, the article 300 defines a mouthpiece 310 located at a proximal end 308. In other embodiments, the device 200 defines this mouthpiece. During use, the user places their mouth over the mouthpiece.

[0132] Device 200 defines a longitudinal axis along which article 300 can extend when inserted into device 200. Opening 214 is aligned on the longitudinal axis. The longitudinal axis can be the axis along which article 300 is inserted into device 200, and therefore the longitudinal axis can be considered as the receiving axis of device 200. Article 300 can similarly have a longitudinal axis along which it is inserted into the device, and this axis can be considered as the insertion axis.

[0133] The aerosol supply device 200 includes a power source 220. The power source 220 may be a battery, such as a rechargeable battery. The device 200 also includes control circuitry 222, which functions as a controller and includes a processor and memory.

[0134] As discussed in detail below, the heating system 110 is configured to heat the aerosol-generating material 302 of the article 300. In some embodiments, the article 300 is consumable and interchangeable with other articles 300. The heating system 110 includes an aerosol generator 304. The heating system 110 includes other components of the aerosol supply system 100, including components of the article 300 and the aerosol supply device 200, such as the power source 220 and control circuitry 222.

[0135] Aerosol generator 304 forms part of article 300. Aerosol generator 304 includes heating device 312 configured to heat aerosol generating material 302 (e.g., to heat at least one of a membrane and a gel) to generate an aerosol. Aerosol generating material may be referred to as aerosolizable material.

[0136] The heating device 312 is a resistance heating device that includes one or more heating elements. In some embodiments, the heating element, or each heating element, is a resistance heating element, as described in detail below. In this configuration, the heating system 110 includes a resistance heating generator that includes components for heating the heating device 312 through a resistance heating process. In this case, current is applied directly to the resistance heating element, and the flow of current in the heating element, which acts as the heating component, causes the heating element to be heated by Joule heating. The resistance heating element comprises a resistive material configured to generate heat when a suitable current flows through the resistive material, and the heating device 312 includes electrical contacts for supplying current to the resistive material. The arrangement of the resistance heating device 312 achieves a compact device. Resistance heating achieves a highly efficient configuration.

[0137] When using the aerosol supply system 100, air is drawn into the air inlet 314 of the article 300, as indicated by arrow 316. The air inlet 314 is located at the distal end of the article 300. In some embodiments, the air inlet 314 may have different configurations, for example, the air inlet may be located on the side. The airflow to the air inlet 314 of the article 300 may be defined, for example, by at least one of an air path through the device 200, an air path located outside the device 200, and an air path between the device 200 and the article 300. The aerosol generated by the aerosol generator 304 exits the device at the aerosol outlet 318, as indicated by arrow 319. In some embodiments, the aerosol outlet 318 is located in the mouthpiece of the article 300, such that the aerosol can be drawn directly from the article 300 into the mouth of the user of the system 100.

[0138] In some exemplary embodiments, the aerosol supply system includes two main components: a control section forming a reusable portion and a consumable section forming a replaceable or disposable portion, which may also be referred to as a replaceable or disposable product or atomizing cartridge. As described herein, the aerosol supply device 200 forms the control section, and the product 300 forms the consumable section. When using the aerosol generation system, the control section and the consumable portion can be releasably connected at an interface. The consumable portion can be removable and replaceable; for example, when the consumable portion is used up, the control section can be reused along with a different consumable portion.

[0139] The aerosol supply system 100 shown is provided by way of example only and is highly illustrative. Different aerosol generating devices and other means may be used in exemplary implementations of the principles described herein. For example, in some exemplary embodiments, air is drawn into an air inlet in a control section, passes through an interface, and then exits the consumable portion.

[0140] like Figure 5 As schematically shown and as described in detail below, article 300 has an article electrical contact configuration 320. In some embodiments, the electrical contact configuration 320 is constituted by an aerosol generator 304. The electrical contact configuration 320 includes a heater electrical contact 322. The heater electrical contact 322 may also be referred to as a heater or an article (electrical) contact. The aerosol supply device 200 includes an electrical connector 230 configured to supply power to an article received by an article receiving unit, for example, to a heating device 321 for heating the aerosol-generating material of article 300. The electrical connector 230 includes a connector electrical contact 232. The connector electrical contact 232 may also be referred to as a connector or a device contact. The article electrical contact configuration 320 is configured to be electrically connected to the device electrical connector 230.

[0141] The configuration of article 300 can be varied. Article 300 includes a body 324. Body 324 is hollow. Body 324 defines a flow path 326 through article 300 (see reference). Figure 6 Flow path 326 extends between air inlet 314 and aerosol outlet 318. Flow path 326 is defined by an internal space within the article along which air and / or aerosol can flow. Flow path 326 is defined within body 324. The aerosol generator or each aerosol generator 304 defines flow path 326. Aerosol generating material 302 is exposed to flow path 326. Aerosol generating material 302 is exposed to the internal space. In some embodiments, the internal space comprises two or more chambers.

[0142] Air inlet 314 includes an opening 315. Opening 315 is formed in body 324. In some embodiments, the opening is formed in another component of article 300, such as in aerosol generator 304 or another wall feature. Aerosol outlet 318 includes an outlet opening 317. Outlet opening 317 is formed in body 324. In some embodiments, outlet opening 317 is formed in another component of article 300, such as in aerosol generator 304 or another wall feature.

[0143] like Figure 6As shown, article 300 includes two aerosol generators 304 to form an aerosol generator configuration. The number of aerosol generators 304 may vary. Each aerosol generator 304 includes an aerosol generating material 302. The aerosol generating material 302 is exposed to a flow path 326. In some embodiments, article 300 includes a single aerosol generator 304. One aerosol generator 304 will be described in detail below, and these details also apply to one or more other aerosol generators 304 in some embodiments.

[0144] The aerosol generator, or each aerosol generator 304 and body 324, is formed in a stacked configuration. In some embodiments, other configurations are contemplated, such as the article being tubular. In such a tubular configuration, the aerosol generator 304 defines a tubular shape. This tubular shape may include a circular cross-section, an elliptical cross-section, and other polygonal shapes.

[0145] In some embodiments, as shown in the accompanying drawings, the article 300 has a planar configuration. That is, the exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and the width, wherein the length is greater than or equal to the width, and wherein the width is greater than the depth. Other configurations are also conceivable.

[0146] Figure 6 This is a partially exploded perspective view of article 300, in which aerosol generator 304 is shown flipped relative to the assembly orientation and spaced apart from other components. Article 300 includes a first aerosol generator 302, a body 324, and a second aerosol generator. The body 324 spaces the first aerosol generator and the second aerosol generator 304 apart. The first aerosol generator and the second aerosol generator 304 enclose an internal space defined by the body 324, along which air and / or aerosol can flow. The aerosol generating materials 302 of the first aerosol generator and the second aerosol generator 304 face each other and are exposed to the internal space. When assembled, the first aerosol generator and the second aerosol generator 304 sandwich the body 324 therebetween. At least in Figure 6 In some embodiments, the first aerosol generator, the second aerosol generator 304, and the body have equal planar areas. In some embodiments, one or more of the first aerosol generator, the second aerosol generator 304, and the body 324 have a greater length and / or width. In some embodiments, one of the first aerosol generator and the second aerosol generator 304 is replaced by a blank panel. The body 324 includes a body layer. The body may include multiple body layers. These body layers may be formed in a stacked manner and arranged to define some features of the article 300, such as the air inlet 314 and the aerosol outlet 318.

[0147] The wrapping layer surrounds the article 300 and forms part of the article 300. The wrapping layer may include a sheet. The wrapping layer acts as a retaining sleeve. The aerosol generator, or each aerosol generator 304, extends from the wrapping layer at its distal end. The exposed electrical contact area 323 of the heater contact portion 322 is exposed at its distal end, for example, referenced to... Figure 2 Other configurations are also conceivable, for example, at least one exposed electrical contact area 323 may additionally or alternatively be defined along a smaller longitudinal surface or edge of the article 300, and defined on a larger surface of the article defined by the aerosol generator 304.

[0148] Aerosol generator 304 Figure 7 The cross-section is shown schematically. Aerosol generator 304 is one implementation of the aerosol generator 304 of the aerosol supply system 100 described above.

[0149] Aerosol generator 304 includes an aerosol generating layer 330. The aerosol generating layer is also referred to as an aerosolizable layer. More generally, aerosol generator 304 may include a heating device (such as a resistance heating layer 340) and an aerosol generating material (such as the aerosol generating layer 330). The aerosol generating layer 330 includes an aerosol generating material 302. Aerosol generator 304 includes a resistance heating layer 340. In some embodiments, the resistance heating layer 340 is formed as a conductive layer. The aerosol generating layer 330 is located on the resistance heating layer 340. The aerosol generating layer 330 is in direct contact with the resistance heating layer 340. In some embodiments, the aerosol generating layer 330 is in indirect contact with the resistance heating layer 340. In some embodiments, the resistance heating layer 340 may include a coating. As described in detail below, the resistance heating layer 340 includes a plurality of resistance heating elements 342, such as... Figure 8 and Figure 9 As shown. The resistance heating element or each resistance heating element 342 forms at least a portion of a conductive path between a pair of electrical contacts 322. The resistance heating element or each resistance heating element 342 provides a conductive path for resistively heating at least a portion of the aerosol generating material 302 to generate an aerosol. In some embodiments, the aerosol generating material 302 is in the form of a film or gel.

[0150] The resistance heating layer 340 is formed as a conductive layer. In some embodiments, the layer takes the form of at least one of a metallic layer (such as an aluminum layer) or a non-metallic material (such as graphene). The resistance heating layer 340 is in the form of a foil, such as an aluminum foil.

[0151] The aerosol generator 304 includes a support 350. In some embodiments, the support 350 comprises paper or cardboard material. The support 350 provides structural support for the aerosol generator 304. A resistance heating layer 340 is located on the support 350. The support 350 is configured as a support layer. Figure 7 As shown, in the aerosol generator 304, the resistance heating layer 340 is sandwiched between the support 350 and the aerosol generating layer 330.

[0152] The support 350 is electrically insulating. The resistance heating layer 340 and the support layer 350 define the substrate 352. The substrate 352 supports the aerosol generation layer 330.

[0153] Article 300 may include a laminated structure 354, which includes a resistance heating layer 340 and a support layer 350. In some embodiments, the laminated structure 354 includes an aerosol generating layer 330. The aerosol generating layer 330 may be formed in a continuous configuration or may be composed of discrete portions. Discrete portions may include one or more of dots, strips, spirals, or other shapes.

[0154] In some embodiments, the aerosol generating layer 330 includes an aerosol generating membrane. In some embodiments, the aerosol generating layer 330 includes multiple aerosol generating membranes. In some embodiments, the aerosol generating membrane includes multiple aerosol generating membrane regions. The multiple aerosol generating membranes and / or the multiple aerosol generating membrane regions may have different characteristics, such as different compositions, thicknesses, densities, at least one of active substances and / or flavorings, one or more aerosol forming agent materials, and optionally one or more other functional materials.

[0155] One or more of the aerosol generating layer 330, the resistance heating layer 340, and the support layer 350 may include additional layers. For example, the support layer 350 may include a backing layer or an intermediate layer. In some embodiments, the support layer 350 is omitted.

[0156] Figure 8 A resistance heating element 342 is shown. The resistance heating layer 340 includes a plurality of resistance heating elements 342. In some embodiments, the resistance heating layer 340 includes a single resistance heating element 342.

[0157] Multiple heating elements 342 can be formed as an array 344, such as Figure 9 As shown. Other configurations can also be envisioned.

[0158] The resistance heating element 342 includes a resistance heating path. The resistance heating path is formed by a conductive path. The resistance heating path is not straight; it is tortuous. The configuration of the resistance heating path can vary. The resistance of the heating element 342 can depend on the properties of the resistance heating path in the conductive layer, such as the path's length, width, thickness, and construction.

[0159] A resistance heating element 342 extends between a first type electrical contact 360 and a second type electrical contact 365. The first type electrical contact 360 is configured to provide a positive electrode contact, and the second type electrical contact 365 is configured to provide a negative electrode contact. Current flows through this path between the first type electrical contact 360 and the second type electrical contact 365. The contact configuration can be reversed. The first type electrical contact 360 and the second type electrical contact 365 are heater electrical contacts 322. The first type electrical contact 360 and the second type electrical contact 365 form at least a portion of the article electrical contact configuration 320.

[0160] The tortuous or meandering nature of the path of the resistance heating element 342 results in a higher resistance compared to the case where there is a straight path between the first type of electrical contact and the second type of electrical contact.

[0161] The resistance heating layer 340 may include a first type of electrical trace 361 extending from the resistance heating element 342. The first type of electrical trace 361 includes a first type of electrical contact 360. The first type of electrical contact 360 is configured to be electrically connected to the device electrical connector 230. The first type of electrical contact 360 includes a first type of exposed contact area 362. The first type of exposed contact area 362 is exposed on the article for direct connection to the device electrical connector 230.

[0162] The resistance heating layer 340 may include a second type of electrical trace 366 extending from the resistance heating element 342. The second type of electrical trace 366 includes a second type of electrical contact 365. The second type of electrical contact 365 is configured to electrically connect to the device electrical connector 230. The second type of electrical contact 365 includes a second type of exposed contact area 367. The second type of exposed contact area 367 is exposed on the article 300 for direct connection to the device electrical connector 230.

[0163] As discussed in detail below, in some embodiments, the conductive path of the resistance heating element 342 is formed by defining at least one electrically insulating barrier 346 in the resistance heating layer 340. In some embodiments, the electrically insulating barrier 346 is formed by cutting electrically insulating barrier limiting portions (i.e., electrically insulating portions) such as gaps, channels, or grooves into a sheet formed of conductive material, thereby forming the resistance heating layer 340. In some embodiments, the resistance heating layer 340 is pre-formed to define the resistance heating element or each resistance heating element 342, and then the resistance heating layer is applied to the support 350. In some embodiments, the resistance heating layer 340 is first applied to the support 350, and then the resistance heating element or each resistance heating element 342 is defined in the resistance heating layer 340. The resistance heating element or each resistance heating element 342 defining the resistance heating layer 340 may be a printed heater. The insulating barrier may be an air gap. In some embodiments, the insulating barrier is a filled gap, such as a filled gap filled with insulating material. The barrier defines a barrier that prevents electrical conduction across the barrier.

[0164] The resistance heating element or each resistance heating element 342 defining the resistance heating layer 340 can be formed by a cutting action. This cutting may include die-cutting. The resistance heating element can be formed by an action applied only to the resistance heating layer. In some embodiments, the resistance heating element can be formed by an action applied to both the resistance heating layer and the support layer, for example, by cutting the resistance heating layer and the support layer.

[0165] At least one electrical insulation barrier 346 defines a first type of electrical trace 361 and a second type of electrical trace 366.

[0166] In some embodiments, the traces of the resistance heating element or each resistance heating element 342 have a width ranging from 0.5 mm to 1 mm (two exemplary examples have widths of 0.93 mm and 0.72 mm, respectively), and the spacing between the traces is less than about 0.25 mm (two exemplary examples have spacings of 0.2 mm and 0.05 mm, respectively). The resistance heating element or each resistance heating element 342 may have an overall size of about 10 mm x 10 mm. In other exemplary embodiments, other sizes are also possible. By forming the resistance heating element or each resistance heating element 342 with these dimensions using an aluminum foil with a thickness of 0.006 mm and a resistivity between 2 µOhmcm and 6 µOhmcm, the resistance of the path is calculated to be about 1 Ohm. In one exemplary embodiment, the measured resistance is between 0.83 Ohm and 1.31 Ohm.

[0167] like Figure 9As shown, the resistance heating layer 340 can be formed as a plurality of resistance heating elements, generally indicated by reference numerals 342a, 342b, 342c, 342d, and 342e. Each of the resistance heating elements 342a-342e extends from a corresponding first-type electrical contact (generally indicated by reference numerals 360a, 360b, 360c, 360d, and 360e) to a single second-type electrical contact 365. The number of electrical contacts can vary. Thus, each resistance heating element 342a-342e extends between discrete first-type electrical contacts and a shared second-type electrical contact.

[0168] Each of the resistance heating elements 342a-342e provides a conductive path for resistively heating a portion of the aerosol generating material 302 to generate an aerosol at a corresponding portion of the aerosol generator 304.

[0169] Individual first-type electrical contacts 360a-360e allow current to be individually supplied to each of the plurality of resistance heating elements 342a-342e. This allows for control of heating different regions of the aerosol generation layer 330. For example, the aerosol generator may be provided with five aerosol generation zones. The resistance heating layer 340 allows each of these zones to be activated individually. Thus, for example, a single consumable incorporating a single aerosol generator 304 can produce five aerosol extractions, and a single consumable incorporating two aerosol generators 304 can produce ten aerosol extractions.

[0170] In the exemplary resistance heating layer 340, a plurality of first-type electrical contacts 360a-360e, such as positive electrical connections, are provided, and a single second-type electrical contact 365, such as a negative electrical connection, is provided. This is not necessary in all implementations. For example, multiple second-type contacts may be provided. In some embodiments, each resistance heating element 342a-342e includes a corresponding first-type electrical contact 360 and a corresponding second-type electrical contact 365.

[0171] exist Figure 9 In the embodiment of the resistance heating layer 340 shown, first-type electrical contacts 360a-360e are arranged on the first edge 363 of the resistance heating layer 340, and second-type electrical contacts 365 are arranged on the second edge 368 of the resistance heating layer 340. This allows for convenient electrical connection, but of course, many other configurations are also possible, some of which will be discussed further below.

[0172] Figure 10This is a flowchart illustrating a portion of a method or algorithm (generally indicated by reference numeral 400) for forming an aerosol generator 304 according to an exemplary embodiment.

[0173] Method or algorithm 400 begins with operation 402, in which a resistance heating layer is formed as one or more heating elements (e.g., multiple heating elements), wherein each resistance heating element extends from a first type of electrical contact to a second type of electrical contact. In use, the heating element or each heating element can be used to provide a conductive path for resistively heating a portion of the aerosol-generating material to generate an aerosol. In the presence of a support, the formation of the resistance heating element or each resistance heating element can be performed before or after the resistance heating layer is applied to the support. The resistance heating layer can be attached to the support, or mounted or formed on the support in different configurations.

[0174] At operation 404, the formed resistance heating layer is arranged to contact the aerosol generation layer, wherein the aerosol generation layer comprises an aerosol generating material. Algorithm 400 can be used to fabricate the aforementioned aerosol generator 304.

[0175] Figure 11 An aerosol generator 304 under construction according to one embodiment is shown. An aerosol generating material 302 is formed on a resistance heating layer 340 by means of, for example, spraying, coating, dispensing, or some other method of deposition. In an exemplary implementation of operation 404, an aerosol generating layer 330 is disposed on the resistance heating layer 340, as indicated by arrow 406.

[0176] Figure 12 A resistance heating layer 340 is shown being formed according to an exemplary embodiment. The resistance heating layer 340 is being cut using a laser cutter 408. Cutting the resistance heating layer 340 can be used to form the path of the heating element described herein. The use of a laser cutter 408 (or some other cutting process) is not the only method that can be used to generate the resistance heating layer 340 described herein. Some exemplary methods will be described below.

[0177] Figure 13 This is a flowchart illustrating a portion of a method or algorithm (generally indicated by reference numeral 410) for forming an aerosol generator 304. The method or algorithm 410 begins at operation 412, in which a resistance heating layer is provided. At operation 414, one or more resistance heating elements are formed in the resistance heating layer by chemical etching. Operations 412 and 414 are an exemplary implementation of operation 402 of the method 400 described above. An aerosol-generating material is then disposed on the resistance heating layer, thereby achieving operation 404 described above.

[0178] Figure 14 This is a flowchart illustrating a portion of a method or algorithm for forming an aerosol generator 304 (generally indicated by reference numeral 418). The method or algorithm 418 begins with operation 420, in which one or more heating elements are formed, at least partially, by printing a resistance heating layer. Thus, operation 420 is an exemplary implementation of operation 402 of the algorithm 400 described above. Aerosol-generating material is then disposed on the resistance heating layer, thereby achieving operation 404 described above.

[0179] The cutting, etching, and printing methods described above are provided by way of example; other additional or alternative methods are also possible. For example, a so-called "hot foiling" method can be used, in which the heating element is made of a resistance heating layer and is then assembled / bonded to a support. Other techniques, such as die-cutting, can also be used. Furthermore, two or more techniques can be combined (e.g., by adding more conductive material, such as additional foil, printing material, etc., the conductivity of the connection traces can be increased). Those skilled in the art will recognize many other techniques or combinations of techniques that can be used in the implementation of the principles described herein.

[0180] Figure 15 This is a flowchart illustrating an operating method or algorithm (generally indicated by reference numeral 424) according to an exemplary embodiment. Method or algorithm 424 can be implemented, for example, using any aerosol generator described herein. Method or algorithm 424 is initiated when a command to initiate heating is received in one example of operation 426. In response to the command to initiate heating, (in operation 428) it is determined whether a heating element is available. As discussed above, multiple heating elements may be provided. Operation 428 may include determining which heating elements have been used and / or which corresponding available aerosol generating materials have been exhausted.

[0181] If a heating element is available, the algorithm moves to operation 430, where the available heating element is used. As discussed above, the heating element can be individually controllable, for example, power can be supplied to a single heating element. After operation 430 is completed, the algorithm terminates at operation 432. If it is determined at operation 428 that no heating element is available, for example because all heating elements have been exhausted, then the algorithm terminates at operation 432. This may mean that the consumable part used to implement algorithm 424 needs to be replaced.

[0182] Figure 16A resistive heating layer 340 in formation according to one embodiment is shown. The resistive heating layer 340 is being cut using a laser cutter 408, but other methods, such as chemical etching or printing, as discussed above, may also be used. The cutting of the conductive layer 340 forms the heating element described herein.

[0183] exist Figure 16 In this embodiment, the cut path is a linear path extending along the length of the conductive layer 120.

[0184] Figure 17 Another embodiment of the resistance heating layer 340 is shown. The resistance heating layer 340 can be formed using the laser cutter 408 described above or similar devices or other methods. The resistance heating layer 340 includes a plurality of resistance heating elements 342, each of which is a linear heating element, comprising a conductive path extending along the length of the resistance heating layer 340. Each resistance heating element 342 extends from a first type electrical contact 360 (e.g., a positive electrical connection) to a second type electrical contact 365 (e.g., a negative electrical contact). In this embodiment, both types of electrical contacts are located at the same end of the resistance heating layer 340 and are arranged adjacent to each other. In this configuration, as in some other embodiments, there is no shared second type electrical contact; instead, each heating element has a separate first type electrical contact and a separate second type electrical contact.

[0185] Figure 18 Another embodiment of the resistance heating layer 340 is shown. The resistance heating layer 340 can be formed using the laser cutter 408 described above or similar devices or other methods. The resistance heating layer 340 includes a plurality of heating elements 342, each of which is a linear heating element and includes a conductive path extending along the length of the resistance heating layer 340. Each resistance heating element 342 extends from a first type of electrical contact 360 (e.g., a positive electrical connection) to a second type of electrical contact 365 (e.g., a negative electrical contact). In such an embodiment, different types of electrical connections are provided at opposite ends of the resistance heating layer 340, and a common second type of electrical contact is provided. Although a linear path is provided here, resistance can be increased by providing a creneled path that acts as a tortuous path. Note that the path in any other embodiment described herein can also be creneled.

[0186] Figure 19The distal end of article 300 is shown. As illustrated, body 324 includes a plurality of body layers 325. The body layers 325 are arranged in a stacked manner. The body layers 325 form a laminated structure. In some embodiments, the body layers 325 are cardboard layers. Other suitable materials may also be used. The body layers 325 are configured to define certain features of article 300. In some embodiments, at least one body layer includes a gap defining an air inlet 315. This gap defines an opening 314.

[0187] The aerosol generator 304 includes a resistance heating layer 340. The resistance heating layer 340 includes a resistance heating element 342, a first type electrical contact 360, and a single second type electrical contact 365. The first type electrical contact provides a positive electrical connection for each of the plurality of heating elements 342, for example, and the single second type electrical contact provides a common negative electrical connection for the plurality of heating elements 342. The first type electrical contact 360 and the second type electrical contact 365 (i.e., heater contact 322) together form at least a portion of the article electrical contact configuration 320 of the aerosol generator 304.

[0188] The resistance heating element 342 is located on the inner side of the resistance heating layer 340. The inner side defines the first side 306 of the aerosol generator 304, as shown below. Figure 3 As shown. The heater contacts 322 are located on the second side 307 of the resistance heating layer 340. The second side 307 defines the outer side of the aerosol generator 304. The heater contacts 322 are exposed so that they can contact the device electrical connector 230. The heater contacts 322 are located on the side of the resistance heating layer 340 opposite to the resistance heating element 342. Other configurations are also conceivable.

[0189] The support layer 350 is located between the inner portion of the resistance heating layer 340 and the outer portion of the resistance heating layer 340.

[0190] A folded portion 370 is formed in the resistance heating layer 340. The folded portion 370 defines the heater contact portion 322. Figures 2 to 4 and Figure 19 As shown, the folded portion 370 extends perpendicular to the longitudinal axis of the aerosol generator 304. The folded portion 370 defines a vane 372. A heater contact portion 322 is located on the vane 372. The vane defines a contact panel. The remainder of the blank defines a main panel.

[0191] In embodiments with support layer 350, support layer 350 is folded in some embodiments. Substrate 352 is folded at fold 370. In some embodiments, support layer 350 terminates at fold 370. In some embodiments, fold 370 extends parallel to the longitudinal axis of aerosol generator 304.

[0192] The folded portion of the resistance heating layer 340 is attached in the folded position. In some embodiments, this folded portion is attached by, for example, adhesive. Other fixing methods are also conceivable.

[0193] Fold portion 370 defines a first type of exposed contact area 362. Fold portion 370 defines a second type of exposed contact area 367. Electrical traces 361 and 366 are electrically connected across fold portion 370. Heater contact portion 322 of first type electrical trace 361 and heater contact portion of second type electrical trace 366 are defined on a second side of resistance heating layer 340. A portion of first type electrical trace 361 and a portion of second type electrical trace 366 extend on a first side of resistance heating layer 340. In some embodiments, the resistance heating element extends from fold portion 370. Other configurations are also contemplated.

[0194] Device 200 includes a plurality of connector electrical contacts 232 of electrical connector 230. The configuration of device connector 230 depends on the configuration of heater contacts 322 of aerosol generator 304. In some embodiments, such as Figure 19 The aerosol generator 300 shown includes a plurality of heater contacts 322, which include a plurality of first-type heater contacts 360 and a second-type heater contact 365. The article 300 includes another set of heater contacts 322 located on the other side of the article 300, corresponding to a second aerosol generator 304.

[0195] Figure 20 A device connector 230 of an aerosol supply device 200 used in some embodiments is shown. The connector 230 has a separate connector electrical contact 232 for connection with a heater contact 322.

[0196] Figure 21 An aerosol supply system 100 is schematically shown. System 100 includes an article 300 and an aerosol supply device 200, both shown in block diagrams. Device 200 includes a first connector electrical contact 230a and a second connector electrical contact 230b.

[0197] When the article 300 is inserted into the aerosol supply device 200, connectors 230a and 230b enable the aerosol supply device 200 to provide regulated or controlled voltage and / or current to the respective first-type heater contacts 360 and second-type heater contacts 365 of the aerosol generator 304. The aerosol supply device 200 may include connector configurations configured to supply power to the connector electrical contacts 230a and 230b. The aerosol supply device 200 may, for example, operate as described above.

[0198] Figure 22 This is a flowchart illustrating a method or algorithm for forming an aerosol generator 304 according to an exemplary embodiment (generally indicated by reference numeral 440).

[0199] Method or algorithm 440 begins with operation 442, in which a resistive heating layer is formed as at least one resistive heating element, which, or each heating element, provides a conductive path for resistively heating at least a portion of the aerosolizable material to generate an aerosol. Exemplary heating elements that may be formed in operation 442 are described elsewhere in this document.

[0200] At operation 442, an aerosol generating material is applied and / or formed on the resistance heating layer.

[0201] Operations 442 and 444 of method or algorithm 440 are similar to (and may be the same as) operations 402 and 404 of method or algorithm 400 described above.

[0202] In operation 446, at least one first-type heater electrical contact is provided on the resistance heating layer. The forming method can be any of the methods described above. In operation 448, at least one second-type heater electrical contact is provided on the resistance heating layer. The forming method can be any of the methods described above.

[0203] In some embodiments, the first type of heater electrical contact and the second type of heater electrical contact are formed along or near a single edge of the resistance heating layer. In some embodiments, the first type of heater electrical contact and the second type of heater electrical contact are formed along or near different edges of the resistance heating layer.

[0204] In some embodiments, the first type of heater electrical contact (e.g., one or more positive electrode connections) is disposed along a first edge of the resistance heating layer. In some embodiments, the second type of heater electrical contact (e.g., one or more negative electrode connections) is disposed along a second edge of the resistance heating layer. Operations 446 and 448 can be performed in different orders or simultaneously. Furthermore, operations 446 and 448 can be performed together with operation 442.

[0205] At operation 450, the resistance heating layer is folded. In some embodiments, the support layer is folded together with the resistance heating layer. In some embodiments, the resistance heating layer is folded such that the electrical contacts of the first type of heater and the electrical contacts of the second type of heater are disposed adjacent to each other, as discussed in detail below.

[0206] Figures 23 to 25 An embodiment of an aerosol generator 304 being formed according to algorithm 440 is shown.

[0207] Figure 23 Another embodiment of an aerosol generator 304 in formation is shown. The resistance heating layer 340 is being cut using a laser cutter 408. A pre-folded configuration defines a blank for forming the aerosol generator 304. In some embodiments, the blank defines a fold line along which it is folded during the formation of the aerosol generator. The aerosol generator 304 blank includes the resistance heating layer 340 and a support layer 350. The resistance heating layer 340 and the support layer 350 define a panel defined by the fold line.

[0208] like Figure 23 As shown, the resistance heating layer 340 is formed as a plurality of heating elements 192, but the number may vary and may be a single element. A plurality of first-type heater electrical contacts 360 (e.g., positive electrical contacts) are provided along a first edge of the conductive layer (shown as one heater electrical contact for each heating element). A single second-type heater electrical contact 365 is provided along a second edge of the resistance heating layer 340. In some embodiments, the heater electrical contacts are spaced apart from the edges. As discussed above, each of the plurality of heating elements extends from the first-type heater electrical contact to the second-type heater electrical contact.

[0209] The path for forming the heating element or each heating element 342 is created by cutting the resistance heating layer 340 using a laser cutter 408. As discussed above, laser forming or some other cutting process is not the only way to produce the resistance heating layer 340 described above. Some exemplary alternatives include chemical etching and printing.

[0210] like Figure 24 As indicated, an aerosol generation layer 200 is provided on the resistance heating layer 340. Then press... Figure 24 The arrows in the diagram indicate the folded blank. In this embodiment, the folded portion is formed parallel to the longitudinal direction of the aerosol generator 304. Two folded portions are formed. A first panel 375 is defined to include a heating element 342. A second panel 376 is formed to include a plurality of first-type electrical contacts 360. A third panel 377 is formed to include second-type electrical contacts 365. An aerosol generating layer 330 is located on the first panel 375. Figure 25 The folded aerosol generator 304 is shown.

[0211] When inserting the article 300 into the article receiving section of the device 200, it is important to ensure that the article 300 is accurately positioned such that the article electrical contacts, such as article electrical contacts 322, 360, 365 (interchangeably referred to as heater electrical contacts), are positioned to engage with the corresponding connector electrical contacts of the device 200 (such as connector electrical contacts 232, 230a, 230b). For example, each article electrical contact must engage the corresponding connector electrical contact in a consistent and repeatable manner. This can be difficult to achieve, especially considering that the article 300 may be repeatedly inserted into the receiving section of the device 200, and that various different articles may be used after each article has been depleted in sequence.

[0212] Figure 26 An embodiment of the aerosol supply system 100 is shown, wherein the connector electrical contact 232 is configured to engage with the article 300 when the article 300 is received in the article receiving section 206, thereby preventing the article from being removed from the article receiving section 206. Figure 28 As depicted, after the article 300 has been (fully) inserted into the article receiving section 206, the connector electrical contact 232 is in contact with the article electrical contact 322 (hereinafter referred to as the "second position"). This contact is such that when a user pulls the article 300 to attempt to remove it from the article receiving section 206, they will experience (at least some degree) resistance, which must be overcome to remove the article 300 from the article receiving section. This resistance helps to hold the article 300 within the article receiving section 206 when the user moves the aerosol supply system 100 during use, and ensures that the engagement between the connector electrical contact 232 and the article electrical contact 322 remains. It also prevents the article 300 from being accidentally removed from the aerosol supply device 200.

[0213] The article's electrical contact 322 can provide an electrical connection to an aerosol generator 304 (of the article 300), which may include a heating device (not visible in this figure). The heating device may include one or more heating elements, such as resistance heating elements, as described in the various embodiments discussed above.

[0214] Although Figure 26The description depicts a configuration where two connector electrical contacts 232 are arranged in this manner; however, this technique is equally applicable to configurations where only one connector electrical contact 232 is arranged in this manner (and other connector electrical contacts may not be arranged in this manner), or to configurations where more than two connector electrical contacts 232 are arranged in this manner (and other connector electrical contacts may not be arranged in this manner). Although discussed in the context of connector electrical contacts 232, these techniques are equally applicable to the context of other connector electrical contacts (such as connector electrical contacts 230a and 230b).

[0215] To achieve this, each connector electrical contact 232 is movable between a first position and a second position, in which the connector electrical contact 232 extends from the first position and is configured to engage (i.e., contact) the article 300 received in the article receiving portion 206. The first position is retracted relative to the second position, such that when in the first position, the connector electrical contact 232 is positioned such that the article 300 can be inserted into the article receiving portion 206. When moving between the first and second positions, all connector electrical contacts 232 are translatable and / or rotatable. In other embodiments, a portion of each connector electrical contact 232 may be movable between the first and second positions; for example, a portion of the connector electrical contact 232 including a surface configured to engage (i.e. contact) the article 300 inserted into and received by the article receiving portion 206 may be movable between the first and second positions, while other portions of the connector electrical contact 232 may remain substantially stationary.

[0216] The connector electrical contact 232 can be pushed from the initial position into a first position, and the connector electrical contact is configured to return to the initial position when no article is inserted into or is being inserted into the article receiving portion 206. This initial position is... Figure 26 As shown in the diagram, the connector electrical contact 232 extends from a first position, for example, fully extended. The connector electrical contact can be configured to be pushed into the first position from the initial position when the article 300 begins to be inserted into the article receiving portion 206. This is illustrated in... Figure 27 The diagram shows the user pushing the article 300 into the article receiving section 206, which causes the article 300 to contact the connector electrical contact 232 in the initial position and pushes the connector electrical contact 232 from the initial position to the first position.

[0217] When the article 300 is further pushed into the article receiving section 206, the connector electrical contact section 232 can then be... Figure 29 The first position shown extends to Figure 28The second position is shown, in which the connector electrical contacts extend from the first position. When the article 300 is fully inserted into the article receiving portion 206, the electrical contacts 232 can extend (i.e., move) from the first position to the second position, such that the electrical contacts are in the correct position necessary for engagement between any connector electrical contacts 232 and article electrical contacts 322, thereby enabling the device 200 to induce heating of the aerosol-generating material of the article 300. This movement of the electrical contacts 232 from the first position to the second position when the article 300 is fully inserted can provide feedback (i.e., sensory feedback) to the user who pushed the article 300 into the article receiving portion 206. For example, when the article 300 is fully inserted, the user can feel a “click” or “tap” (in the form of a vibration of the device 200), corresponding to the movement of the electrical contacts 232 from the first position to the second position. This visually informs the user that the article 300 is fully inserted and is now safely held in the aerosol supply device 100. Alternatively, the movement of the electrical contact 232 in the manner described above can generate an audible sound that can be heard by the user. Alternatively, the device 200 can be configured to include, for example, a suitable transparent component, so that the user can observe the movement of the electrical contact 232 as described above.

[0218] When in the second position, the connector electrical contact 232 can engage (e.g., can be shaped to engage) one or more corresponding engagement features 395 of the article 300. The one or more engagement features 395 may include one or more recesses and / or one or more protrusions that engage with the connector electrical contact 232 when the article 300 is received in the article receiving portion 206 and the connector electrical contact 232 is in the second position. In this configuration, the engagement of the one or more engagement features 395 with the connector electrical contact 232 can prevent the article 300 from being removed from the article receiving portion 206. Such engagement features 395 may be optional, and in the absence of such engagement features 395, the connector electrical contact 232 in the second position can prevent the article 300 from being removed by frictional engagement with the article electrical contact 322. In some embodiments, attempting to move the article 300 relative to the device 200 can result in engagement between the connector electrical contact 232 and the engagement features 395. For example, contact between the connector electrical contact 232 and the edge of the engagement feature 395 (e.g., the edge of the recess) can prevent the movement of the article 300. The recess may thus include the edge engaged by the connector electrical contact 232.

[0219] In some implementations, such as Figure 26As depicted, one or more recesses are provided by one or more openings 396 in an insulating outer layer (such as support layer 350), which expose one or more article electrical contacts 232. This configuration, where the openings 396 in the insulating outer layer expose one or more article electrical contacts 232, ensures that the connector electrical contacts 232, when in the second position, engage the article 300 in the article receiving portion 206, while simultaneously forming an electrical connection between it and the article electrical contacts 232. Support layer 250 may include multiple sublayers. For example, sublayers may be in the form of paper or cardboard.

[0220] The connector electrical contacts 232 can move between a first position and a second position because each connector electrical contact 232 is deformable. For example, each connector electrical contact 232 may include a spring, such as a leaf spring, which can be pushed into the first position (e.g., from the initial position) and bias the connector electrical contact 232 from the first position to the second position.

[0221] Alternatively, each connector electrical contact 232 can be mounted to a deformable member (such as a spring) or to an elastic block comprising a resiliently deformable material (such as rubber). The effect is the same: each connector electrical contact 232 can be pushed into a first position (e.g., from an initial position) and biased from the first position to a second position. For example, the aerosol supply device 200 may include a plurality of spring pins, each including a deformable member and a connector electrical contact 232, thereby allowing the connector electrical contact 232 to translate between the first and second positions.

[0222] In any of the above embodiments, the second position adopted by the connector electrical contact 232 (e.g., Figure 28 (As shown) can basically correspond to Figure 26 The initial position of the connector electrical contacts shown is shown.

[0223] In some implementations, such as Figures 26 to 29 As depicted, the connector electrical contact 232 may include a first electrical contact 232 and a second connector electrical contact 232, which are arranged to act on a first side and an opposite second side of the article 300. This configuration can advantageously ensure that the article 300 remains horizontal within the article receiving portion 206 and provide a more uniform force to hold the article 300 within the article receiving portion 206.

[0224] Furthermore, in some embodiments, at least one of the connector electrical contacts 232 includes a leaf spring (e.g., as shown in the image). Figures 26 to 29As shown in the diagram, the leaf spring includes a tilted portion that engages with the article when it is inserted into the article receiving portion 206. The article 300 is inserted along the receiving axis, and the angle between the receiving axis and the tilted portion does not exceed 45°, for example, not more than 35°, for example, not more than 30°. This reduces the initial contact force between the article 300 and the connector electrical contact 232, thereby making it easier for the user to insert the article 300 into the article receiving portion 206.

[0225] Figure 29 and Figure 30 A schematic diagram of a portion of an aerosol supply device 200 according to another embodiment is shown, with emphasis on the connector 230 of the aerosol supply device. The device 200 may include one or more actuators 233 configured to move the connector electrical contacts 232 between a first position and a second position, such as... Figure 29 and Figure 30 As depicted. One or more actuators 233 may be controlled by a controller (e.g., the controller of device 200, such as control circuitry 220). The controller may be configured to, in response to a first article detection sensor 299 configured to detect whether article 300 has begun insertion into article receiving section 206, detect the beginning of article insertion, or additionally or alternatively, in response to a predetermined operation applied by a user to one or more control elements 298 of aerosol supply device 200, cause one or more actuators 233 of aerosol supply device 200 to move connector electrical contacts 232 (e.g., from an initial position) to a first position, such as... Figure 29 What is depicted.

[0226] The controller can also be configured to, in response to a second article detection sensor 297 configured to detect whether the article 300 has been fully inserted into the article receiving section 206, detect that the article has been fully inserted, cause one or more actuators 233 of the aerosol supply device 200 to remove the connector electrical contact 232 from the article receiving section 206. Figure 29 The first position depicted in the middle is moved to Figure 30 The second position is depicted as such that the connector electrical contacts are in the correct position necessary for engagement between any connector electrical contact 232 and article electrical contact 322, thereby enabling the device 200 to induce heating of the aerosol-generating material of the article 300. Alternatively, the connector electrical contacts 232 may be moved in response to a predetermined operation applied by a user to one or more control elements 298 of the aerosol supply device 200.

[0227] The above-described configuration of using actuator 233 to move connector electrical contact 232 advantageously allows connector electrical contact 232 to move to or has been used. Figure 29The first position shown allows for easier insertion of the article 300. It also allows for easier removal of the article 300 when needed, as the connector electrical contact 232 can be driven back into the first position as required. This configuration also allows for selective control of the engagement between the connector electrical contact 232 and the article contact.

[0228] The aerosol supply device 200 may also include a mechanical component 296, which may include a button, and also may include a switch or a slider. The mechanical component 296 may be configured to be user-operated to move the connector electrical contact 232 between a second position and a first position. For example, the mechanical component 296 may be configured to be user-operated to move the connector electrical contact 232 from an initial position to a first position, and user-operated to move the connector electrical contact 232 from the first position to a second position. The mechanical component 296 may act directly on the connector electrical contact 232. In other embodiments, at least one intermediate member may be arranged between the mechanical component 296 and the connector electrical contact 232, and the at least one intermediate member may be configured such that movement of the mechanical component drives movement of the connector electrical contact 232.

[0229] In an embodiment of the invention, the heating device is part of the article 300 and may be part of an aerosol generator, which in turn constitutes part of the article 300.

[0230] In some embodiments of the different configurations of the aerosol generator and articles described above, the aerosol generating material is not formed in the configuration of an aerosol generating layer. In some embodiments, the aerosol generating material is in the form of an aerosol generating segment. The aerosol generating segment typically comprises a solid material. This solid material may be shredded tobacco. For example, the aerosol generating material arranged in the form of an aerosol generating segment may include multiple individual aerosol generating material sheets. The aerosol generating material may be a single tobacco material sheet. In some embodiments, the aerosol generating material includes multiple strip-shaped, bead-shaped, or pellet-shaped aerosol generating materials. In some embodiments, the aerosol generating segment is a block of material.

[0231] In some embodiments, the aerosol generating section includes a material body. The aerosol generating material is non-liquid. In this embodiment, the material body includes aerosol generating material rods, such as tobacco rods. For example, the material body may include shredded tobacco material. The material body may be formed in a rod shape. In some embodiments, the material body includes shredded tobacco formed in a rod shape. The aerosol generating material may include tobacco material. The aerosol generating material may include extruded tobacco. The aerosol generating material may include reconstituted tobacco.

[0232] Aerosol-generating materials, which form solid materials, may contain nicotine. Aerosol-generating materials may include tobacco, be composed of tobacco, or be substantially composed of tobacco. In some embodiments, the aerosol-generating material does not contain tobacco.

[0233] In any of the above embodiments, heating of the article allows volatile compounds to be released relatively stably into the inhalable medium. In the above embodiments, the aerosol-generating section is a block of material. The article may include a mouthpiece section. A tubular element may be positioned between the aerosol-generating material and the mouthpiece section. The article may include a ventilation area located in the mouthpiece section. The mouthpiece section may define a mouthpiece configured to be placed between the user's lips.

[0234] In any of the embodiments of the above-described article, the resistance heating element, or each resistance heating element, is configured to heat substantially the entire aerosol-generating material. In some embodiments, the aerosol-generating section is at least generally columnar. In some embodiments, the aerosol-generating section is at least partially enclosed by a resistance heating layer. In some embodiments, the resistance heating element extends within the aerosol-generating section. The resistance heating element may extend around the aerosol-generating section. In some embodiments, the resistance heating element surrounds the aerosol-generating section. In some configurations, at least a portion of the flow path through the article passes through the aerosol-generating section. The aerosol-generating section may define a portion of an air path. In some embodiments, first-type electrical contacts and second-type electrical contacts are exposed from the aerosol-generating section.
