Consumables may also comprise an aerosol generator, such as a heater, which generates heat during use to cause the aerosol-generating material to produce an aerosol. The heater may comprise a conductor that can be heated by the passage of an electric current through it.
[0132] A non-combustible aerosol supply system may comprise a modular assembly that includes both a reusable aerosol supply device and interchangeable aerosol products. In some implementations, the non-combustible aerosol supply device may comprise a power supply and a controller (or control circuit). The power supply may comprise a power source such as a battery or rechargeable battery. In some implementations, the non-combustible aerosol supply device may also comprise an aerosol generating component. However, in other implementations, the aerosol product may comprise the aerosol generating component partially or entirely.
[0133] Figure 1 shows a schematic diagram of the aerosol supply system 100. The aerosol supply system 100 comprises an aerosol supply device 200 and an article 300 containing an aerosol generating material 302 (see Figure 3). The article 300 removed from the aerosol supply device 200 is shown in Figure 2. The aerosol generator 304 of the article 300 is shown in Figure 3 along with a perspective view of the first side 306, and a perspective view of a portion of the second side 307 is shown in Figure 4.
[0134] Article 300 comprises an aerosol generator 304. The aerosol generator 304 is configured to generate an aerosol from an aerosol-generating material 302 when the aerosol supply system 100 is in operation, as will be described in detail below.
[0135] The aerosol supply system 100 is elongated and may extend along its longitudinal axis. The aerosol supply system 100 has a proximal end 102 that is closest to the user (e.g., the user's mouth) when used by the user to inhale the aerosol generated by the aerosol supply system 100, and a distal end 104 that is furthest from the user when used.
[0136] The proximal end may also be called the “mouth end.” Thus, the aerosol delivery system 100 also defines a proximal direction, which is directed toward the user during use. Furthermore, the aerosol delivery system 100 similarly defines a distal direction, which is directed away from the user during use. The terms proximal and distal, applied to the features of the system 100, are explained by referring to the relative positioning of such features relative to each other in the proximal-distal direction along the longitudinal axis.
[0137] Article 300 is received by an aerosol supply device 200. The configuration of article 300 and the aerosol supply device 200 may vary. In this embodiment, the aerosol supply device 200 comprises a device body 202. The device has a housing 204 that encloses the components of the device 200. As shown in Figure 5, an article receiving portion 206, sometimes called a device chamber, is configured to receive a portion of article 300. The proximal end 308 of the article protrudes from the device 200 when article 300 is received into the device chamber 206. A receptacle 208 defines the chamber 206. The receptacle 208 comprises a receptacle base 210 and a receptacle periphery 212. The configuration of the receptacle 208 may vary depending on the configuration of article 300.
[0138] One or more user-operable control elements 224, such as buttons or switches, may be provided on the aerosol supply device 200 that can be used to operate the aerosol supply system 100. For example, a user may activate the system 100 by pressing a control element 224. One or more user-operable control elements may be omitted. In some embodiments, the aerosol supply system 100 is operated by another user action, such as a puff activated by the user drawing air through the system.
[0139] The aerosol supply device 200 has an opening 214 at its proximal end that leads into the device chamber 206. The opening 214 is provided at one end, and an article 300 can be inserted through this opening. In some embodiments, the article 300 may be fully or partially inserted into the device 200. The configuration of the device 200 may vary; for example, the opening may be located within the longitudinal side wall of the device 200 and / or may be closed by another feature of the device 200 during use. In this configuration, the article 300 defines a mouthpiece 310 at its proximal end 308. In other embodiments, the device 200 defines a mouthpiece. The user places their mouth over the mouthpiece during use.
[0140] Device 200 defines a longitudinal axis along which article 300 may extend when inserted into device 200. The opening 214 is aligned on the longitudinal axis. The longitudinal axis may also be the axis along which article 300 is inserted into device 200. The longitudinal axis may be considered the receiving axis of device 200. Article 300 may also have a longitudinal axis along which it is inserted into the device, and this axis may be considered the insertion axis.
[0141] The aerosol supply device 200 includes a power supply 220. The power supply 220 may be a battery, for example, a rechargeable battery. The device 200 also includes a control circuit 222 that functions as a controller, which includes a processor and memory.
[0142] As will be discussed in detail below, the heating system 110 is configured to heat the aerosol-generating material 302 of article 300. In various embodiments, article 300 is a consumable and interchangeable with other articles 300. The heating system 110 comprises an aerosol generator 304. The heating system 110 comprises article 300 and other components of the aerosol supply system 100, including components of the aerosol supply device 200, such as a power supply 220 and a control circuit 222.
[0143] The aerosol generator 304 forms part of the article 300. The aerosol generator 304 includes a heating component 312 configured to heat at least one of the aerosol-generating material 302, such as a film and a gel, in order to generate an aerosol. The aerosol-generating material may also be called an aerosolizable material.
[0144] The heating element 312 is a resistance heating element. The heating element or each heating element in the embodiments is a resistance heating element, as will be described in detail below. In such an arrangement, the heating system 110 comprises a resistance heating generator which includes components for heating the heating element 312 by a resistance heating process. In this case, a current is applied directly to the resistance heating element, and the heating element is heated by Joule heating due to the resulting current flow within the heating element which acts as a heating element. The resistance heating element includes a resistance material configured to generate heat when a suitable current passes through the resistance material, and the heating element 312 comprises electrical contacts for supplying current to the resistance material. The provision of the resistance heating element 312 enables a compact configuration. Resistance heating provides an efficient configuration.
[0145] In the use of 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, on the side. The airflow to the air inlet 314 of the article 300 may be defined by at least one of the following: an air path through the device 200, an air path 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 so that the aerosol is drawn directly from the article 300 to the user's mouth of the system 100.
[0146] In some exemplary embodiments, an aerosol supply system comprises two main components: a control section forming a reusable portion and a consumable section forming a replaceable or disposable portion, which may be called a replaceable or disposable article or cartridge. As described herein, the aerosol supply device 200 forms the control section, and the article 300 forms the consumable section. In the use of the aerosol generation system, the control section and the consumable section may be releasably connected at an interface. The consumable section may be removable and replaceable, for example, when the consumable section is used, and the control section is reused with another consumable section.
[0147] The illustrated aerosol supply system 100 is provided merely as an example and is highly schematic. Different aerosol generating devices and other devices may be used in exemplary implementations of the principles described herein. For example, in some exemplary embodiments, air is drawn into the air inlet of the control section, passes through the interface, and exits the consumption section.
[0148] As schematically shown in Figure 5 and described in detail below, article 300 has article electrical contact configuration 320. In various embodiments, the electrical contact configuration 320 is formed by the aerosol generator 304. The electrical contact configuration 320 includes a heater electrical contact 322. The heater electrical contact 322 may also be known as a heater contact or article contact. The aerosol supply device 200 includes an electrical connector 230. The electrical connector 230 includes a connector electrical contact 232. The connector electrical contact 232 may also be known as a connector or device contact. The article electrical contact configuration 320 is configured to communicate electrically with the device electrical connector 230.
[0149] The configuration of article 300 may vary. As described herein, the article is a flat article or consumable. The outer surface of article 300 has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and width, where the length is greater than or equal to the width and the width is greater than the depth. In some embodiments, the article is tubular; that is, article 300 has a tubular configuration. In such an arrangement, the aerosol generator may have a tubular configuration.
[0150] Article 300 comprises a body 324, which is hollow. The body 324 defines a flow path 326 (see Figure 6) through Article 300. The flow path 326 extends between an air inlet 314 and an aerosol outlet 318. The flow path 326 is defined by an internal space through which air and / or aerosols can flow within the article. The flow path 326 is defined within the body 324. An aerosol generator or each aerosol generator 304 borders the flow path 326. The aerosol generating material 302 is exposed to the flow path 326. The aerosol generating material 302 is exposed within the internal space. In various embodiments, the internal space comprises one chamber, or the internal space comprises two or more chambers.
[0151] The air inlet 314 includes an opening 315. The opening 315 is formed within the main body 324. In some embodiments, the opening is formed within another component of the article 300, such as an aerosol generator 304 or another wall feature. The aerosol outlet 318 includes an outlet opening 317. The outlet opening 317 is formed within the main body 324. In some embodiments, the outlet opening 317 is formed within another component of the article 300, such as an aerosol generator 304 or another wall feature.
[0152] As shown in Figure 6, article 300 comprises two aerosol generators 304 that form an aerosol generator configuration. The number of aerosol generators 304 may vary. Each aerosol generator 304 contains an aerosol generating material 302. The aerosol generating material 302 is exposed to a channel 326. In some embodiments, article 300 comprises a single aerosol generator 304. One of the aerosol generators 304 is described in detail, and such details are applicable to one or more further aerosol generators 304 in some embodiments.
[0153] The aerosol generator or each aerosol generator 304 and the main body 324 are formed in a layered configuration. In some embodiments, other structures such as tubular structures of articles are envisioned. In such tubular structures, the aerosol generator 304 defines a tubular structure. The tubular shape may include a circular cross-section, an elliptical cross-section, and other polygonal shapes.
[0154] In various embodiments, as shown in the figures, article 300 has a flat configuration. That is, the outer surface of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and width, where the length is greater than or equal to the width, and the width is greater than the depth. Other configurations are conceivable.
[0155] Figure 6 is a partially exploded perspective view of article 300, inverted from its assembled orientation and shown in a spaced-out relationship with other components. Article 300 comprises a first aerosol generator 302, a body 324, and a second aerosol generator. The body 324 separates the first and second aerosol generators 304. The first and second aerosol generators 304 close off an internal space defined by the body 324 through which air and / or aerosols can flow. The aerosol-generating materials 302 of the first and second aerosol generators 304 are exposed to the internal space facing each other. When assembled, the first and second aerosol generators 304 sandwich the body 324. In the embodiment of Figure 6, at least the first and second aerosol generators 304 and the body have equal planar area. In some embodiments, one or more of the first and second aerosol generators 304 and the body 324 have a greater length and / or width. In some embodiments, one of the first and second aerosol generators 304 is replaced by a blank panel. The body 324 comprises a body layer. The body may comprise multiple body layers. The body layers are formed within a stack and may be arranged to define feature parts of the article 300, such as an air inlet 314 and an aerosol outlet 318.
[0156] The wrap surrounds the article 300 and forms part of the article 300. The wrap may include a sheet. The wrap functions as a fixing sleeve. The aerosol generator or each aerosol generator 304 protrudes from the wrap at its distal end. The exposed electrical contact area 323 of the heater contact 322 is exposed at its distal end; see, for example, Figure 2. Other configurations are conceivable, for example, at least one exposed electrical contact area 323 may be additionally or alternatively defined on the main surface of the article defined by the aerosol generator 304, along the short longitudinal surface or edge of the article 300.
[0157] The aerosol generator 304 is schematically shown in cross-section in Figure 7. The aerosol generator 304 is an implementation of the aerosol generator 304 of the aerosol supply system 100 described above.
[0158] The aerosol generator 304 comprises an aerosol generating layer 330, also known as an aerosolizable layer. The aerosol generating layer 330 contains an aerosol generating material 302. The aerosol generator 304 also comprises a resistance heating layer 340, which in some embodiments 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 will be described in detail below, the resistance heating layer 340 comprises a plurality of resistance heating elements 342, for example, as shown in Figures 8 and 9. Each resistance heating element or each resistance heating element 342 forms at least a portion of the conductive path between a pair of electrical contacts 322. Each resistance heating element or resistance heating element 342 provides a conductive path for resistance heating at least a portion of the aerosol generating material 302 to generate an aerosol. In various embodiments, the aerosol generating material 302 is in the form of a film or a gel.
[0159] The resistance heating layer 340 is formed as a conductive layer. In various embodiments, this layer takes the form of at least one of a metal 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, for example, an aluminum foil.
[0160] The aerosol generator 304 comprises a support 350. In various embodiments, the support 350 includes paper or card material. The support 350 provides structural support for the aerosol generator 304. The resistance heating layer 340 is located on the support 350. The support 350 is configured as a support layer. As shown in Figure 7, in the aerosol generator 304, the resistance heating layer 340 is sandwiched between the support 350 and the aerosol generation layer 330.
[0161] 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 generating layer 330.
[0162] Article 300 may comprise a laminate 354 having a resistance heating layer 340 and a support layer 350. In some embodiments, the laminate 354 comprises an aerosol generating layer 330. The aerosol generating layer 330 may be formed as a continuous structure or from separate parts. The separate parts may comprise one or more of dots, strips, helices, or other shapes.
[0163] In some embodiments, the aerosol-generating layer 330 comprises an aerosol-generating film. In some embodiments, the aerosol-generating layer 330 comprises a plurality of aerosol-generating films. In some embodiments, the aerosol-generating film comprises a plurality of aerosol-generating film regions. Such plurality of aerosol-generating films and / or plurality of aerosol-generating film regions may have different properties, such as different compositions, thicknesses, densities, active substances and / or flavors, one or more aerosol-forming agent materials, and optionally at least one or more other functional materials.
[0164] One or more of the aerosol generation layer 330, the resistance heating layer 340, and the support layer 350 may comprise further layers. For example, the support layer 350 may comprise a backing layer or an intermediate layer. The support layer 350 is omitted in some embodiments.
[0165] Figure 8 shows one of the resistance heating elements 342. The resistance heating layer 340 comprises a plurality of resistance heating elements 342. In some embodiments, the resistance heating layer 340 comprises a single resistance heating element 342.
[0166] Multiple heating elements 342 may be formed in an array 344 as shown in Figure 9. Other configurations are also possible.
[0167] The resistive heating element 342 includes a resistive heating path. The resistive heating path is formed as a conductive path. The resistive heating path is nonlinear. The resistive heating path is folded. The configuration of the resistive heating path may be varied. The electrical resistance of the heating element 342 may depend on the properties of the resistive heating path in the conductive layer, such as the length, width, thickness and arrangement of the path, as well as the material.
[0168] The resistive heating element 342 extends between the first type of electrical contact 360 and the second type of electrical contact 365. The first type of electrical contact 360 is configured to provide a positive contact, and the second type of electrical contact 365 is configured to provide a negative contact. Current flows through the path between the first type of electrical contact 360 and the second type of electrical contact 365. The contact arrangement may be reversed. The first and second type of electrical contacts 360, 365 constitute the heater electrical contact 322. The first and second type of electrical contacts 360, 365 form at least a portion of the article electrical contact configuration 320.
[0169] The bending or meandering nature of the path of the resistive heating element 342 is such that the electrical resistance of the path increases compared to a straight path between the first and second types of electrical contacts.
[0170] The resistance heating layer 340 may include a first type of electrical track 361 extending from the resistance heating element 342. The first type of electrical track 361 includes a first type of electrical contact 360. The first type of electrical contact 360 is configured to electrically connect 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.
[0171] The resistance heating layer 340 may include a second type of electrical track 366 extending from the resistance heating element 342. The second type of electrical track 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.
[0172] As will be discussed in detail below, the conductive path of the resistive heating element 342 in various embodiments is created by defining at least one electrically insulating barrier 346 within the resistive heating layer 340. In some embodiments, the electrically insulating barrier 346 is formed by introducing an electrically insulating barrier limiting portion (i.e., an electrically insulating portion), such as a gap, channel, or slot, into a sheet formed of a conductive material to form the resistive heating layer 340. In some embodiments, the resistive heating layer 340 is pre-formed to define the resistive heating element or each resistive heating element 342 and then applied to the support 350. In some embodiments, the resistive heating layer 340 is applied to the support 350, and the resistive heating element or each resistive heating element 342 is then defined within the resistive heating layer 340. The resistive heating element or each resistive heating element 342 defining the resistive heating layer 340 may be a printed heater. The insulating barrier may be an air gap. In some embodiments, the insulating barrier is, for example, a filled gap filled with an insulating material. A barrier defines a barrier to electrical conduction across it.
[0173] The resistive heating elements defining the resistive heating layer 340 or each resistive heating element 342 may be formed by a cutting action. The cutting may include die cutting. The resistive heating elements may be formed by an action applied only to the resistive heating layer. In some embodiments, the resistive heating elements may be formed by an action applied to both the resistive heating layer and the support layer, for example, by an action that cuts the resistive heating layer and the support layer.
[0174] At least one electrical insulating barrier 346 defines first and second types of electrical tracks 361, 366.
[0175] In some embodiments, the tracks of the resistive heating element or each resistive heating element 342 have a width of 0.5 mm to 1 mm (two exemplary prototypes have widths of 0.93 mm and 0.72 mm, respectively) and a gap between tracks of less than approximately 0.25 mm (the same two exemplary prototypes have gaps of 0.2 mm and 0.05 mm, respectively). The resistive heating element or each resistive heating element 342 may have overall dimensions of approximately 10 mm × 10 mm. Other dimensions are possible in other exemplary embodiments. By forming resistive heating elements or each resistive heating element 342 of these dimensions from aluminum foil with a thickness of 0.006 mm and an electrical resistivity of 2 to 6 μOhmcm, the resistance of the path is calculated to be approximately 1 ohm. In one exemplary embodiment, the resistance was measured between 0.83 and 1.31 ohms.
[0176] As shown in Figure 9, the resistive heating layer 340 may be formed in multiple resistive heating elements, collectively referred to as reference numbers 342a, 342b, 242c, 342d, and 342e. Each of the resistive heating elements 342a to 342e extends from one of the first type electrical contacts, collectively referred to as reference numbers 360a, 360b, 360c, 360d, and 360e, to a single second type electrical contact 365. The number of electrical contacts may vary. Thus, each resistive heating element 342a to 342e extends between individual first type electrical contacts and a common second type electrical contact.
[0177] Each of the resistance heating elements 342a to 342e provides a conductive path for resistance heating a portion of the aerosol generating material 302 in order to generate an aerosol in each part of the aerosol generator 304.
[0178] The separate first types 360a-360e of electrical contacts allow current to be supplied individually to each of the multiple resistive heating elements 342a-342e. This allows for control of heating of different zones of the aerosol generation layer 330. For example, the aerosol generator may have five aerosol generation zones. The resistive heating layer 340 allows each of these zones to be activated individually. Thus, for example, five aerosol puffs may be produced from a single consumable incorporating a single aerosol generator 304, or ten aerosol puffs may be produced from a single consumable incorporating two aerosol generators 304.
[0179] In the exemplary resistance heating layer 340, a plurality of first type electrical contacts 360a to 360e, for example, positive electrical connections, and a single second type electrical contact 365, for example, a negative electrical connection, are provided. This is not essential for all implementation configurations. For example, multiple second type contacts could be provided. In various embodiments, each resistance heating element 342a to 342e comprises one corresponding to a first type electrical contact 360 and one corresponding to a second type electrical contact 365.
[0180] In the embodiment of the resistance heating layer 340 shown in Figure 9, the first type of electrical contacts 360a to 360e are located on the first edge 363 of the resistance heating layer 340, and the second type of electrical contacts 365 are located on the second edge 368 of the resistance heating layer 340. This allows for convenient power connections, but of course, many other configurations are possible, some of which will be discussed further below.
[0181] Figure 10 is a flowchart showing part of a method or algorithm for forming an aerosol generator 304, generally denoted by reference numeral 400, according to an exemplary embodiment.
[0182] Method or algorithm 400 begins with operation 402, in which a resistive heating layer is formed on one or more heating elements (e.g., multiple heating elements), each resistive heating element extending from a first type of electrical contact to a second type of electrical contact. When in use, the heating elements or each heating element may be used to provide a conductive path for resistively heating a portion of the aerosol-generating material to generate an aerosol. The formation of the resistive heating elements or each resistive heating element may be performed before or after applying the resistive heating layer on a support if a support is present. The resistive heating layer may be bonded to the support, or mounted or formed on the support in different configurations. In various embodiments, the aerosol-generating material is mounted on the support with respect to the resistive heating layer, as described below with reference to, for example, Figures 26-28.
[0183] In operation 404, the formed resistance heating layer is positioned to be in contact with the aerosol generating layer, which incorporates the aerosol generating material. The aerosol generator 304 described above can be produced using algorithm 400.
[0184] Figure 11 shows an aerosol generator 304 formed according to one embodiment. The aerosol generating material 302 is formed on the resistance heating layer 340 by depositing the aerosol generating material, for example, by spraying, painting, extruding, or some other method. In an exemplary implementation of operation 404, the aerosol generating layer 330 is disposed on the resistance heating layer 340 as indicated by arrow 406.
[0185] Figure 12 shows a resistance heating layer 340 formed according to an exemplary embodiment. The resistance heating layer 340 is in the process of being cut using a laser cutter 408. The cutting of the resistance heating layer 340 can be used to form the path of the heating element described herein. The use of the laser cutter 408 (or any other cutting process) is not the only way in which the resistance heating layer 340 described herein can be produced. Several exemplary methods are described below.
[0186] Figure 13 is a flowchart illustrating part of a method or algorithm for forming an aerosol generator 304, generally indicated by reference numeral 410. The method or algorithm 410 begins in operation 412, where a resistive heating layer is provided. In operation 414, one or more resistive heating elements are formed within the resistive heating layer by chemical etching of the resistive heating layer. Operations 412 and 414 are exemplary implementations of operation 402 of method 400 described above. Then, in operation 416, an aerosol generating material is disposed on the resistive heating layer. Thus, operation 416 is an exemplary implementation of operation 404 described above.
[0187] Figure 14 is a flowchart illustrating part of a method or algorithm for forming an aerosol generator 304, generally indicated by reference numeral 418. The method or algorithm 418 begins in operation 420, where 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 algorithm 400 described above. Next, in operation 422, the aerosol generating material is placed on the resistance heating layer. Thus, operation 422 is an exemplary implementation of operation 404 described above.
[0188] The cutting, etching, and printing methods described above are provided as examples. Other additional or alternative methods are also possible. For example, a so-called "thermal foil stamping" approach can be used, in which the heating element is fabricated from a resistive heating layer and then assembled / bonded onto a support. Yet another technique, such as die-cutting, can also be used. Furthermore, two or more techniques can be combined (for example, conductivity can be added to the connection trace by adding more conductive materials such as additional foil or printing material). Those skilled in the art will recognize many further techniques, or combinations of techniques, that can be used in implementations of the principles described herein.
[0189] Figure 15 is a flowchart illustrating an exemplary embodiment of an operating method or algorithm, collectively referred to as reference numeral 424. The method or algorithm 424 may be carried out, for example, using one of the aerosol generators described herein. The method or algorithm 424 is initiated when a command to initiate heating is received within a fraction of an instant of operation 426. In response to the command to initiate heating, a decision is made as to whether a heating element is available (operation 428). Multiple heating elements may be provided, as discussed above. Operation 428 may include a decision as to which heating element was used and / or whether the corresponding available aerosol generating material has been exhausted.
[0190] If heating elements are available, the algorithm proceeds to operation 430, where available heating elements are used. As discussed above, heating elements may be individually controllable, for example, by supplying power to individual heating elements. Once operation 430 is complete, the algorithm terminates with operation 432.
