The aerosol generating apparatus 10 includes a battery 11 (e.g., a rechargeable battery), control circuitry 12, and an aerosol generator 13. As discussed in detail below, the aerosol generator 13 includes a resistance heater for heating an aerosolizable material (e.g., a membrane or gel) to generate an aerosol (e.g., vapor). The aerosolizable material is sometimes referred to as an aerosol generating material.

[0168] The aerosol generating apparatus 10 forms an aerosol supply system, which includes an aerosol supply device and an article including an aerosol generator 13. The resistance heater includes at least one resistance heating element.

[0169] Battery 11 acts as a power source. The control circuit acts as a controller and includes a processor and storage. The control circuit is configured to implement the methods described below.

[0170] In use of device 10, air is drawn into the air inlet of aerosol generator 13, as indicated by arrow 16. The aerosol generated by aerosol generator 13 exits the device at the air outlet, as indicated by arrow 17 (e.g., into the mouth of the user of device 10).

[0171] In some exemplary embodiments, the aerosol generating device 10 includes two main components: a control section 2 (which may be referred to as a reusable component) and a consumable component 4 (which may be referred to as a replaceable or disposable cartridge). During use of the aerosol generating device 10, the control section 2 and the consumable component 4 can be releasably connected at an interface 6. The consumable component 4 can be removable and replaceable (e.g., when the consumable component is depleted), wherein the control section 2 can be reused with different consumable components.

[0172] The aerosol generating device 10 (also known as an aerosol supply system) includes a control section 2 (which may also be called an aerosol supply device 10) and a consumable component 4 (also known as a product 4).

[0173] The aerosol generator 13 forms part of the article 4. The aerosol generator 13 includes a resistance heating configuration configured to heat an aerosol generating material (e.g., at least one of a membrane or gel) to generate an aerosol.

[0174] In embodiments, the heating element(s) are resistance heating elements, as described in detail below. In such configurations, the system includes a resistance heating generator comprising components for heating the heating configuration via a resistance heating process. In this case, current is applied directly to the resistance heating element, and the current flow in the heating element, which acts as the heating component, causes the heating element to be heated by Joule heating. The resistance heating element includes a resistive material configured to generate heat when a suitable current passes through it, and the heating configuration includes electrical contacts for supplying current to the resistive material.

[0176] Of course, the aerosol generating device 10 is provided by way of example only and is highly illustrative. Many alternative aerosol generating devices and other devices can be used in exemplary implementations of the principles described herein. For example, in some exemplary embodiments, air is drawn into an air inlet in the control section 2, passes through interface 6, and exits the consumable component 4.

[0177] Aerosol generator 13 is configured to generate aerosols from an aerosol-generating material (also referred to as an aerosolizable material) during operation of the aerosol supply system, as described in detail below. The aerosol supply system 10 is elongated and extends along a longitudinal axis. The aerosol supply system 10 has a proximal end that is closest to the user (e.g., the user's mouth) when the user inhales the aerosol generated by the aerosol supply system 10 during use, and a distal end that is furthest from the user during use. The proximal end may also be referred to as the "mouth end." The aerosol supply system 10 is accordingly defined in a proximal direction guiding the user during use. Furthermore, the aerosol supply system 10 is similarly defined in a distal direction guiding the user away from the user during use. The terms "proximal" and "distal" used to describe the features of system 10 will be described with reference to the relative positioning of these features relative to each other in the proximal-distal direction along the longitudinal axis.

[0178] In an embodiment, the aerosol generator 13 may be fully or partially inserted into the aerosol supply device 10. The configuration of the aerosol supply device 10 may vary; for example, the opening may be located in the longitudinal sidewall of the aerosol supply device 10, and / or may be closed during use by another feature of the aerosol supply device 10. In this configuration, the article 4 defines a mouthpiece at its proximal end. In an embodiment, the aerosol supply device 10 defines a mouthpiece. The user places their mouthpiece on the mouthpiece during use.

[0179] Figure 2 This is a block diagram of an aerosol generator according to an exemplary embodiment, indicated generally by reference numeral 20. Aerosol generator 20 is an exemplary embodiment of aerosol generator 13 of the aerosol generating apparatus 10 described above.

[0180] The aerosol generator 20 includes an aerosolizable layer 22 (bonded with an aerosolizable material) and a conductive layer 24 in contact with the aerosolizable layer. As described in detail below, the conductive layer 24 is formed as one or more heating elements, each providing a conductive path for resistive heating of a portion of the aerosolizable material in the aerosolizable layer 22 to generate an aerosol. The aerosolizable material may be, for example, in the form of a film or a gel.

[0181] The aerosolizable layer 22, also known as the aerosol generating layer 22, includes aerosolizable materials, also known as aerosol generating materials.

[0182] The conductive layer 24 is formed as a resistance heating layer. The resistance heating layer includes a material that is resistively heated in response to an electric current passing through it.

[0183] The aerosol generator 20 includes a resistance heating layer 24. An aerosol generating layer 22 is located on the resistance heating layer 24. The aerosol generating layer 22 is in direct contact with the resistance heating layer 24. In an embodiment, the aerosol generating layer 22 is in indirect contact with the resistance heating layer 24. In an embodiment, the resistance heating layer 24 may include a coating. The coating of the resistance heating layer 24 may be located on a conductive material.

[0184] The conductive layer 24 may be in the form of a metallic layer such as an aluminum layer or a non-metallic material such as graphene. The conductive layer may be in the form of a foil (e.g., aluminum foil).

[0185] The aerosol generator 20 is configured to generate aerosols from aerosol generating materials when the aerosol supply system 10 is operated, as will be described in detail below.

[0186] Figure 3 This is a block diagram of an aerosol generator according to an exemplary embodiment, indicated generally by reference numeral 30. Aerosol generator 30 is an exemplary embodiment of the aerosol generator 13 described above.

[0187] The aerosol generator 30 includes the aerosolizable layer 22 and conductive layer 24 described above. The aerosol generator 30 further includes a support (or substrate) 32. The support 32 may include paper or card material providing structural support for the aerosol generator 30. Figure 3 As shown, in the aerosol generator 30, the conductive layer 24 is located between the support member 32 and the aerosolizable layer 22.

[0188] In this embodiment, a conductive layer (also referred to as the resistance heating layer 24) is located on the support 32. The support 32 is configured as a support layer. The support 32 is electrically insulating. The resistance heating layer 24 and the support layer 32 define a substrate. The substrate 32 supports the aerosol generation layer 22.

[0189] In one embodiment, the aerosol generator 30 includes a layer comprising a resistance heating layer 24 and a support layer 32. In another embodiment, the layer includes an aerosol generating layer 22. The aerosol generating layer 22 may be formed in a continuous configuration or may be formed from discrete portions. The discrete portions may include one or more of dots, strips, spirals, or other shapes. In another embodiment, the discrete portions are aligned with the resistance heating element.

[0190] One or more of the aerosol generating layer 22, the resistance heating layer 24, and the support layer 32 may include another layer. For example, the support layer 32 may include a backing layer or an intermediate layer. In this embodiment, the support layer 32 is omitted.

[0191] The aerosol generators 30 are formed in a stacked configuration. Other configurations of the article are envisioned in the embodiments, such as tubular configurations. In such tubular configurations, the aerosol generators 30 define the tubular shape. The tubular shape may include a circular cross-section and other polygonal shapes.

[0192] In one embodiment, as shown in the figure, article 30 has a flat configuration. That is, the exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to both 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 contemplated.

[0193] Figure 4 A heating element according to an exemplary embodiment is shown, which is generally indicated by reference numeral 40. One or more heating elements 40 may be formed from the conductive layer 24 described above.

[0194] The heating element 40 includes a non-linear conductive path between a first electrical connection structure 42 and a second electrical connector 43. In some exemplary embodiments, the first electrical connection structure 42 provides a positive connection and the second electrical connection structure 43 provides a negative connection, such that current flows through the path between these electrical connection structures. The tortuous or meandering nature of the path of the heating element 40, compared to the linear path between the first and second electrical connectors, increases the resistance of the path.

[0195] The conductive path defines the resistive heating path. The resistive heating path is formed by the conductive path. The resistive heating path is non-linear. The resistive heating path is coiled. The configuration of the resistive heating path can vary. The resistance of the heating element 40 can depend on the properties of the resistive heating path in the conductive layer, such as the path's length, width, thickness, and configuration. The resistance of the resistive heating path can also depend on the material forming the resistive heating path.

[0196] The first electrical connection structure and the second electrical connection structure may be referred to as a first type of electrical contact 42 (or a first type of electrical contact) and a second type of electrical contact 43 (or a second type of electrical contact), respectively. The contact configuration may be reversed. The first type of electrical contact and the second type of electrical contact define the heater electrical contact. The first type of electrical contact 42 and the second type of electrical contact 43 form at least a portion of the article's electrical contact configuration.

[0197] As discussed in detail below, the conductive path of the heating element 40 can be established by forming tracks within the heating element, for example, by cutting tracks in the conductive layer constituting the heating element. In some exemplary embodiments, the tracks may have a width of approximately 0.5 mm to 1 mm (two exemplary prototypes have widths of 0.93 mm and 0.72 mm, respectively) and a gap of less than approximately 0.25 mm between the tracks (two identical exemplary prototypes have gaps of 0.2 mm and 0.05 mm, respectively). The heating element may have an overall size of approximately 10 mm × 10 mm. Of course, other sizes are possible in other exemplary embodiments. By forming a heating element of this size from an aluminum foil with a thickness of 0.006 mm and a resistivity between 2 µOhmcm and 6 µOhmcm, the resistance of the path has been calculated to be approximately 1 ohm. In one exemplary embodiment, the resistance was measured to be between 0.83 ohms and 1.31 ohms.

[0198] The resistance heating layer includes multiple resistance heating elements 40. The multiple heating elements 40 are formed in an array, according to... Figure 5 As shown in the diagram. The array of heating elements can be arranged in a single row. The array of heating elements can be arranged in a single row along the longitudinal axis of the aerosol generator. The array of heating elements can be arranged in a single row transversely to the longitudinal axis of the aerosol generator. Other configurations are envisioned.

[0199] The resistance heating layer 24 includes a first-type electrical track 44 extending from the resistance heating element 40. The first-type electrical track 44 includes a first-type electrical contact 42. The first-type electrical contact 42 is configured for electrical connection with a device electrical connector. The first-type electrical contact 42 includes a first-type exposed contact area. The first-type exposed contact area is exposed on the article for direct connection with the device electrical connector.

[0200] The resistance heating layer 24 includes a second type of electrical track 45 extending from the resistance heating element 40. The second type of electrical track 45 includes a second type of electrical contact 43. The second type of electrical contact 43 is configured for electrical connection with a device electrical connector. The second type of electrical contact 43 includes a second type of exposed contact area. The second type of exposed contact area is exposed on the article for direct connection with the device electrical connector.

[0201] In one embodiment, the conductive path of the heating element is established by defining at least one electrically insulating barrier in the resistive heating layer 24. In another embodiment, the electrically insulating barrier is formed by cutting conductive limiting elements (i.e., electrically insulating portions) such as gaps, channels, or slots in a sheet formed of conductive material to form the resistive heating layer 24. In another embodiment, the resistive heating layer 24 is pre-formed to define the one or more resistive heating elements 40 and then applied to the support 32. In yet another embodiment, the resistive heating layer 24 is applied to the support 32, and the one or more resistive heating elements 40 are then defined within the resistive heating layer 24. The one or more resistive heating elements 40 defining the resistive heating layer 24 may be printed heaters. At least one electrically insulating barrier defines electrical tracks of both the first and second types. The electrically insulating barrier is an electrically conductive barrier that extends through the barrier.

[0202] The insulating barrier may be an air gap. In an embodiment, the insulating barrier is a filled gap, for example, filled with an insulating material. The barrier is a barrier that limits electrical conduction through it.

[0203] The resistive heating element defining the resistive heating layer can be formed by a cutting action. Cutting may include die-cutting. The resistive heating element can be formed by an action applied only to the resistive heating layer. In an embodiment, the resistive heating element can be formed by an action applied to both the resistive heating layer and the support layer, such as cutting the resistive heating layer and the support layer.

[0204] Figure 5 A conductive layer according to an exemplary embodiment is shown, which is indicated generally by reference numeral 50. The conductive layer 50 is an exemplary embodiment of the heating element 24 of the aerosol generator 20 or 30 described above.

[0205] The conductive layer 50 is formed into a plurality of heating elements, which are generally indicated by reference numerals 51 to 55. Each of the heating elements 51 to 55 extends from a first type of electrical connection structure (connection structures 56a to 56e, respectively) to a second type of electrical connection structure (connection structure 58).

[0206] The number of electrical connection structures (also referred to as electrical contacts) can vary. Thus, each resistance heating element 51 to 55 extends between discrete first-type electrical contacts 56a to 56e and common second-type electrical contacts 58.

[0207] When layer 50 is used as heating element 24 of aerosol generator 20 or 30, each of heating elements 51 to 55 provides a conductive path for resistive heating of a portion of the aerosolizable material of support 22 to generate aerosol at the corresponding portion of the support.

[0208] The individual first-type electrical connection structures 56a to 56e allow current to be independently supplied to each of the multiple heating elements 51 to 55. Therefore, heating of different zones of the aerosolizable material can be controlled. For example, the aerosol generator may be provided with five aerosol generation zones. Layer 50 allows each of these zones to be activated separately. Thus, for example, five streams of aerosol can be generated from a single consumable incorporating heating elements 51 to 55.

[0209] Therefore, for example, five aerosols can be generated from a single consumable with a single aerosol generator 20 or 30, and ten aerosols can be generated from a single consumable with two aerosol generators 20 or 30.

[0210] In the exemplary conductive layer 50, a plurality of first-type electrical connection structures 56a to 56e (e.g., positive electrical connection structures) are provided, and a single second-type connection structure 58 (e.g., negative electrical connection structure) is provided. This is not necessary for all embodiments. For example, a plurality of second-type connection structures may be provided.

[0211] In the embodiment, each of the resistive heating elements 51 to 55 includes a corresponding one of the first type of electrical contacts 42 and a corresponding one of the second type of electrical contacts 43.

[0212] In the exemplary conductive layer 50, a first type of electrical connection structure is disposed on a first edge of the conductive layer, and a second type of electrical connection structure is disposed on a second edge of the conductive layer. This allows for convenient electrical connections, but of course, many other combinations are possible, some of which are discussed further below.

[0213] Figure 6 A flowchart illustrating an algorithm according to an exemplary embodiment is provided, the algorithm being indicated in its entirety by reference numeral 60.

[0214] Algorithm 60 begins with operation 62, in which the conductive layer is formed as one or more heating elements (e.g., multiple heating elements), each extending from a first type of electrical connection structure to a second type of electrical connection structure. In use, the heating elements can be used to provide a conductive path for resistive heating of a portion of an aerosolizable material to generate an aerosol.

[0215] In the presence of a support, the resistance heating element or the resistance heating layer may be formed before or after the resistance heating layer is applied to the support. The resistance heating layer may be adhered to the support, or mounted or formed on the support in different configurations.

[0216] At operation 64, the formed conductive layer is arranged to contact the aerosolizable layer, wherein the aerosolizable layer is bonded with an aerosolizable material.

[0217] In other words, at operation 64, at least one of the formed resistance heating layer and aerosol generation layer is arranged to contact another component, wherein the aerosol generation layer is incorporating an aerosol generation material. Alternatively, the aerosol generation layer is formed on the resistance heating layer.

[0218] Therefore, algorithm 60 can be used to generate the aerosol generator 20 described above (e.g., containing conductive layer 50).

[0219] Figure 7 An aerosol generator being formed according to an example embodiment is shown, generally indicated by reference numeral 70. The aerosol generator 70 includes a conductive layer 72 and an aerosolizable layer 74 containing an aerosolizable material. The aerosolizable material can be formed on the layer 74, for example, by deposition, such as by spraying, coating, dispensing, or some other method.

[0220] In one example implementation of operation 62 of the above algorithm 60, the conductive layer 72 is formed as a plurality of heating elements. The conductive layer 72 may be, for example, the conductive layer 50 described above.

[0221] In an example implementation of operation 64 of algorithm 60, the conductive layer 72 and the aerosolizable layer 74 are arranged to be in contact with each other (as indicated by arrow 76).

[0222] Figure 8 This shows a conductive layer 80 being formed according to an example embodiment. The conductive layer 80 is cut using a laser cutter 82. The cutting of the conductive layer 80 can be used to form the path of the heating element described herein.

[0223] The use of a laser cutter 82 (or some other cutting program) is not the only way to produce the conductive layer described herein. Some example methods are described below.

[0224] Figure 9 The following is a flowchart of an algorithm according to an example embodiment, which is generally indicated by reference numeral 90.

[0225] Algorithm 90 begins at operation 92, in which a conductive layer is provided. In operation 94, one or more heating elements are formed in the conductive layer by chemical etching. Operations 92 and 94 are example implementations of operation 62 of algorithm 60 described above. The conductive layer is then arranged to contact the aerosolizable layer, thereby performing operation 64 as described above.

[0226] Figure 9The flowchart can also be considered a portion showing the method or algorithm for forming aerosol generators 20, 30, and 70. In an embodiment, the method or algorithm 90 begins at operation 92, where a resistive heating layer is provided. In operation 94, one or more of these resistive heating elements are formed in the resistive heating layer by chemical etching. Operations 92 and 94 are an example implementation of operation 62 of the method 60 described above. The aerosol generating material is then disposed on the resistive heating layer, thereby implementing operation 64 described above.

[0227] Figure 10 The following is a flowchart of an algorithm according to an example embodiment, which is generally indicated by reference numeral 100.

[0228] Algorithm 100 begins at operation 102, in which the heating element is formed at least partially by printing a conductive layer. Operation 102 is therefore an example implementation of operation 62 of algorithm 62 described above. The conductive layer is then arranged to contact the aerosolizable layer, thereby performing operation 64 as described above.

[0229] Figure 10 The flowchart, which may also be referred to as a portion showing the method or algorithm for forming aerosol generators 20, 30, and 70, is generally indicated by reference numeral 100. This method or algorithm 100 begins at operation 102, in which one or more heating elements are formed, at least partially, by printing a resistive heating layer. Operation 102 is therefore an example implementation of operation 62 of the aforementioned algorithm 60. The aerosol-generating material is then disposed on the resistive heating layer, thereby implementing operation 64 as described above.

[0230] The cutting, etching, and printing methods described are provided by way of example; alternative methods are also possible. For example, a so-called "thermal foil bonding" method can be used, in which the heating element is made of a conductive layer and then assembled / bonded to the substrate. Other techniques, such as die-cutting, can also be used. Furthermore, two or more techniques can be combined (e.g., conductivity can be increased to the connection traces by adding more conductive material, such as additional foil, printing material, etc.). Those skilled in the art will recognize many further techniques or combinations of techniques that can be used to implement the principles described herein.

[0231] In this embodiment, the resistance heating layer and the support member can be cut together. The resistance heating layer can be bonded to the support member to form a resistance heating element. The support member can be cut together with the resistance heating layer. The support member and the resistance heating layer can be aligned. The support member and the resistance heating layer can be cut into the same shape. The support member and the resistance heating layer can be formed into the same shape. The support member and the resistance heating layer can be cut together using die cutting.

[0232] Figure 11The following is a flowchart of an algorithm according to an example embodiment, generally indicated by reference numeral 110. Algorithm 110 can be implemented, for example, using any of the aerosol generators described herein.

[0233] In an example of operation 112, algorithm 110 is initiated upon receiving a command to activate heating. In response to the command to activate heating, it is determined (in operation 114) whether a heating element is available. As discussed above, multiple heating elements may be available. Operation 114 may involve determining which of these heating elements have been used (and the corresponding available aerosolizable material has been exhausted).

[0234] If a heating element is available, the algorithm proceeds to operation 116, where the available heating element is used. As discussed above, the heating element can be individually controllable, for example, by providing power to a separate heating element. Once operation 116 is complete, the algorithm terminates in operation 118.

[0235] If, in operation 114, it is determined that no heating element is available (e.g., because all heating elements have been used), the algorithm terminates in operation 118. This may mean that the consumable parts used to implement algorithm 110 need to be replaced.

[0236] In the above example embodiments, the heating element includes a non-linear conductive path (e.g., a tortuous or meandering path) between the first electrical connection structure 42 and the second electrical connector 43. This is not necessary for all example embodiments. Some alternative configurations are illustrated below by way of example.

[0237] Figure 12 This illustrates the formation of a conductive layer 120 according to an example embodiment. The conductive layer 120 is cut using a laser cutter 122 (similar to the laser cutter 82 described above), but other methods (such as chemical etching or printing, as discussed above) may be used. The cutting of the conductive layer 120 forms the path of the heating element illustrated herein.

[0238] The path cut by the laser cutting machine 122 is a linear path extending along the length of the conductive layer 120.

[0239] Figure 13 The conductive layer according to the example embodiment is shown, generally indicated by reference numeral 130. The conductive layer 130 can be formed using the laser cutter 122 described above or some similar device.

[0240] The conductive layer 130 includes a plurality of heating elements, each of which is a linear heating element and includes a conductive path extending across the length of the support. Each heating element extends from a first type of electrical connection structure (e.g., a positive electrical connection structure) to a second type of electrical connection structure (e.g., a negative electrical connection structure). In the example layer 130, the two types of electrical connection structures are located at the same ends of the layer and are positioned adjacent to each other. Therefore, the example path of the layer 130 extends from one end of the layer to the other and then returns, rather than a meandering path. It should be noted that there is no common second connection structure as in some other example embodiments; instead, each heating element has a separate first electrical connection structure and a separate second electrical connection structure.

[0241] Figure 14 The conductive layer according to the example embodiment is shown, generally indicated by reference numeral 140. The conductive layer 140 can be formed using the laser cutter 122 described above or some similar device.

[0242] In other words, the resistance heating layer 80 can be formed using the laser cutting machine 82 described above or some similar device or another method. Each resistance heating element extends from one of the first type of electrical contacts (e.g., a positive electrical contact) to a second type of electrical contact (e.g., a negative electrical contact).

[0243] Conductive layer 140 includes a plurality of heating elements, each of which is a linear heating element and includes a conductive path extending across the length of a support. Each heating element extends from a first type of electrical connection structure (e.g., a positive electrical connection structure) to a second type of electrical connection structure (e.g., a negative electrical connection structure). In the example layer 140, the types of electrical connection structures are positioned at opposite ends of the layer, and a common second (negative) connection structure is provided. Although a linear path (rather than a zigzag path) is provided, resistance is provided by providing a zigzag path. Note that the path in any other embodiment described herein may also be zigzag.

[0244] Figure 15 This illustrates a portion of an aerosol generator 150 according to an example embodiment. As discussed above, the aerosol generator 150 may include: a conductive layer having a plurality of first-type electrical connection structures (e.g., providing a positive electrical connection structure for each of a plurality of heating elements); and a single second-type electrical connection structure (e.g., providing a common negative electrical connection structure for these plurality of heating elements).

[0245] In other words, article 300 has an article electrical contact configuration. This electrical contact configuration is formed by an aerosol generator 150 in this embodiment. The electrical contact configuration includes heater electrical contacts 152 and 154. These heater electrical contacts may also be referred to as heaters or article contacts 152 and 154. The aerosol supply device includes an electrical connector 160, such as... Figure 16 As shown. The electrical connector includes connector electrical contacts. These connector electrical contacts may also be referred to as connector or device contacts. The product electrical contacts are configured to be in electrical communication with the device electrical connector 160.

[0246] The first and second type of electrical contacts 42 and 43, i.e. heater contacts, together form at least part of the product electrical contact configuration of aerosol generators 20, 30, and 70.

[0247] A resistance heating element 40 is located on the inner side of the resistance heating layer 80. This inner side defines a first side of the aerosol generator 150. Heater contacts 42 and 43 are located on a second side of the resistance heating layer 80. This second side defines an outer side of the aerosol generator 150. These heater contacts are exposed to allow them to contact the device's electrical connector. These heater contacts are located on the side of the resistance heating layer 80 opposite the resistance heating element. Other configurations are contemplated.

[0248] The support layer 32 is located between the inner portion of the resistance heating layer 80 and the outer portion of the resistance heating layer 80.

[0249] The aerosol generator 150 includes multiple external connectors, the configuration of which depends on the configuration of the first and second types of electrical connection structures of the aerosol generator. For example, Figure 15 The aerosol generator shown includes: a plurality of external connectors, indicated by reference numeral 152 (each connected to one of a first type of electrical connection structure); and additional external connectors 154 (connected to a second type of electrical connection structure). The aerosol generator 150 may have additional external connectors on the underside of the device corresponding to these connectors 152 and 154. Figure 15 (Not visible in the middle).

[0250] Figure 16 The connector 160 shown is used in some embodiments. The connector has separate pins for connection with electrical contacts, such as connectors 152 and 154 described above.

[0251] The configuration of article 300 is variable. Article 300 includes a body 302. Body 302 may be hollow. Body 302 may define a flow path through article 300. The flow path extends between an air inlet and an aerosol outlet. This flow path is defined by an internal space within the article, along which air and / or aerosol can flow. This flow path is defined within body 302. The aerosol generator 150 or each aerosol generator 150 constrains this flow path. Aerosol generating material is exposed to the flow path. Aerosol generating material is exposed within this internal space. This internal space, in embodiments, includes two or more chambers.

[0252] exist Figure 15 The distal end of article 300 is shown in the image. As shown, body 302 includes a plurality of body layers. These body layers are configured as a stack of body layers 304. These body layers form a layered structure. These body layers are card layers in this embodiment. Other suitable materials may be used. These body layers 304 are configured to define features of article 300. At least one body layer in this embodiment includes a gap defining an air inlet. This gap defines an opening 306.

[0253] The air inlet includes an opening 306. This opening is formed in the body 302. In an embodiment, the opening 306 is formed in another component of the article 300, such as the aerosol generator 150 or another wall feature. The aerosol outlet includes an outlet opening. The outlet opening is formed in the body 302. In an embodiment, the outlet opening is formed in another component of the article 300, such as the aerosol generator 150 or another wall feature.

[0254] In one embodiment, article 300 may include two aerosol generators 150 configured as aerosol generators. The number of aerosol generators 150 may be different. Each aerosol generator 150 includes an aerosol generating material. The aerosol generating material is exposed to a flow path. In another embodiment, article 300 includes a single aerosol generator 150.

[0255] Figure 17 This is a block diagram of an aerosol generating apparatus according to an example embodiment, generally indicated by reference numeral 170. The system includes the aerosol generator 150 described above, first and second connectors 160a and 160b (similar to connector 160 described above), and a control section 172.

[0256] Control section 172 is similar to the above reference. Figure 1 The control section 2 of the aerosol generating device 10 is described. The aerosol generator 150 is similar to the consumable component 4 of the aerosol generating device 10. When the aerosol generator 150 is inserted into the control section 172 (e.g. Figure 17As shown, connectors 160a and 160b enable control section 172 to supply regulated or controlled voltage and / or current to various electrical connection structures of the first and second types of aerosol generator 150. Control section 172 may include connector configurations configured to supply power to these connectors 160a and 160b (and thus to the conductive layer of the aerosol generator). Control section 172 may, for example, implement the algorithm 110 described above.

[0257] Control section 172 is sometimes referred to as a non-combustible aerosol generating device. Aerosol generator 150 is sometimes referred to as a "product" or "consumable".

[0258] In this embodiment, the article 300 may be received by the aerosol supply device 170. The configuration of the article 300 and the aerosol supply device 170 may vary.

[0259] Figure 18 The following is a flowchart of an algorithm according to an example embodiment, which is generally indicated by reference numeral 180.

[0260] Algorithm 180 begins with operation 181, in which a conductive layer is formed as one or more heating elements, each of which provides a conductive path for resistively heating a portion of the aerosolizable material to generate an aerosol. Example heating elements that may be formed in operation 181 are described in detail elsewhere in this document.

[0261] In operation 182, the formed conductive layer is arranged to contact the aerosolizable layer, wherein the aerosolizable layer contains an aerosolizable material.

[0262] Operations 181 and 182 of Algorithm 180 are similar to (and may be identical to) operations 62 and 64 of Algorithm 60 described above.

[0263] In operation 183, one or more electrical connection structures of the first type (e.g., positive connection structures) are disposed along a first edge of the conductive layer. In operation 184, one or more electrical connection structures of the second type (e.g., negative electrical connection structures) are disposed along a second edge of the conductive layer. Each heating element extends from the first type electrical connection structure to the second type electrical connection structure. Of course, operations 183 and 184 can be performed in a different order or simultaneously. Furthermore, operations 183 and 184 can be performed together with operation 181.

[0264] In other words, in operation 183, at least one first-type electrical contact is disposed on the resistance heating layer. The forming method can be any of the methods described above. In operation 184, at least one second-type electrical contact is disposed on the resistance heating layer. The forming method can be any of the methods described above.

[0265] In one embodiment, these first and second type electrical contacts are formed along or near a single edge of the resistance heating layer. In another embodiment, these first and second type electrical contacts are formed along or near different edges of the resistance heating layer.

[0266] In operation 185, the conductive layer and the aerosolizable layer are folded so that the first and second types of electrical connection structures are arranged adjacent to each other, as discussed in detail below.

[0267] In one embodiment, the support layer is folded together with the resistance heating layer.

[0268] Figures 19 to 21 This illustrates an aerosol generator formed according to algorithm 180 according to an example embodiment.

[0269] Figure 19 This illustrates a conductive layer 190 forming an aerosol generator according to an example embodiment. The conductive layer 190 is cut using a laser cutter 192.

[0270] like Figure 19 As shown, the conductive layer is formed into a plurality of heating elements 193. A plurality of electrical connection structures 194 of a first type (e.g., positive electrical connection structures) are disposed along a first edge of the conductive layer (one connection structure is shown for each heating element). A second type of electrical connection structure 195 is disposed along a second edge of the conductive layer. As discussed above, each of the plurality of heating elements extends from the first type of electrical connection structure to the second type of electrical connection structure.

[0271] The conductive layer 190 forms the path of the heating element 193 through cutting by the laser cutter 192. As discussed above, the use of the laser cutter 192 (or some other cutting process) is not the only method to produce the conductive layer described above. Some example alternative methods include chemical etching and printing.

[0272] like Figure 20 As indicated, the aerosolizable layer 200 is configured to contact the conductive layer 190, and the aerosolizable layer contains an aerosolizable material. The aerosol generator (including the conductive layer 190 and the aerosolizable layer 200) is then folded, as... Figure 20 As indicated by the arrow in the image.

[0273] In this embodiment, the folds are formed parallel to the longitudinal direction of the aerosol generator. Two folds are formed. The first panel is defined to include a heating element 193. The second panel is formed to include a plurality of first-type electrical contacts 194. The third panel is formed to include second-type electrical contacts 195. The aerosol generating layer 200 is on the first panel. In this embodiment, a single fold is formed in the aerosol generator.

[0274] In one embodiment, where a support layer 32 is present, the support layer 32 is folded. The substrate is folded at this fold. In one embodiment, the support layer 32 ends at this fold. In one embodiment, the fold extends parallel to the longitudinal axis of the aerosol generator 150. In another embodiment, the support layer 32 is not folded.

[0275] Figure 21 The folded aerosol generator is shown, indicated by reference numeral 210.

[0276] In one embodiment, the folded portion of the resistance heating layer 190 is secured in the folded position. This folded portion is adhered in this embodiment, for example, by bonding. Other securing components are contemplated.

[0277] In one embodiment, the fold defines a first type of exposed contact area. The fold also defines a second type of exposed contact area. Electrical tracks are electrically connected across the fold. Heater contacts of both the first and second type of electrical tracks are defined on a second side of the resistance heating layer 190. Portions of both the first and second type of electrical tracks extend on a first side of the resistance heating layer 190. In one embodiment, a resistance heating element extends from the fold. Other configurations are contemplated.

[0278] The article 300 includes another set of heater contacts on the opposite side of the article 300, corresponding to the second aerosol generator 150.

[0279] A pre-folded configuration defines a blank for forming the aerosol generator 150. In this embodiment, the blank defines fold lines along which folds are made during the formation of the aerosol generator. The aerosol generator 150 blank includes a resistance heating layer 190 and a support layer 32. The resistance heating layer 190 and the support layer 32 define a panel defined by the fold lines.

[0280] Figure 22 This is a side view of an aerosol generator, generally indicated by reference numeral 220. Aerosol generator 220 may be the aerosol generator 210 described above.

[0281] The aerosol generator includes: an aerosolizable layer 222 comprising an aerosolizable material; a first electrical connection structure 224 (only one of which is visible); and a second electrical connection structure 225. These first and second electrical connection structures can be positive and negative connection structures, respectively. The aerosolizable layer 222 can be the aerosolizable layer 200 described above. The connection structures 224 and 225 can be the connection structures 194 and 195 described above.

[0282] The aerosol generator 220 can be formed by folding the conductive layer 190 described above so that the first and second types of electrical connection structures are arranged adjacent to each other. In some applications, this simplifies the supply of power to the aerosol generator.

[0283] Figure 23 This is a schematic plan view of a non-combustible aerosol generating apparatus according to an exemplary embodiment, generally indicated by reference numeral 230. The apparatus 230 is configured to receive an aerosol generator, article, or consumable (such as the aerosol generator 220 described above). The apparatus 230 is an example of control section 2 of the aerosol generating apparatus 10 described above.

[0284] The non-combustible aerosol generating device 230 includes a connector configuration configured to supply power to first and second types of connection structures (e.g., positive and negative connection structures) of the aerosol generator. For example, the connector configuration of the device 230 includes a plurality of first connection structures 232 for supplying power to the first type of connection structure and a single connection structure 234 for supplying power to the second type of connection structure.

[0285] See, for example Figure 24 An embodiment of an aerosol generator including a single fold is shown. This fold is defined by a fold line 198. Fold 198 is formed in a conductive layer 190. This fold defines a heater contact 193 on a first panel 196. The fold extends parallel to the longitudinal axis of the aerosol generator. Fold 198 defines a second panel 197. Heater contacts 194 and 195 are on the second panel 197. The second panel 197 defines a contact panel. The remainder of the blank defines the first panel 196. Fold line 198 is predefined in this embodiment. This fold line extends perpendicular to the longitudinal direction, although other configurations are contemplated. The fold line is linear. The second panel 197 includes a plurality of first-type electrical contacts 194 and second-type contacts 195. As shown, a single second-type electrical contact 195 is present. In this embodiment, a plurality of second-type electrical contacts 195 are present. As shown, each of the plurality of first-type electrical contacts 194 and second-type contacts 195 is on the second panel 197. In one embodiment, at least one of the plurality of first-type electrical contacts 194 and second-type contacts 195 is located on the first panel 197. The second panel defines an electrical contact area. In this embodiment, a single electrical contact area exists. By utilizing a single fold, alignment of the article contacts and the device contacts can be made simpler. Manufacturing of the device and the article can also be simplified because tolerance accumulation may be reduced.

[0286] In some embodiments of the different arrangements of the aerosol generator and article described above, the aerosol generating material is formed in a configuration different from that of the aerosol generating layer. In some embodiments, the aerosol generating material is in the form of an aerosol generating section. The aerosol generating section typically comprises a solid material. Such a solid material can be tobacco. For example, the aerosol generating material arranged as an aerosol generating section can include multiple individual aerosol generating material sheets. The aerosol generating material can be individual tobacco material sheets. In some embodiments, the aerosol generating material includes multiple strips, beads, or pellets. In some embodiments, the aerosol generating section is a material plug.

[0287] In one embodiment, the aerosol generating section includes a material body. The aerosol generating material is non-liquid. In such an embodiment, the material body includes an aerosol generating material rod, such as a tobacco rod. For example, the material body may include shredded tobacco material. The material body may be formed as a rod. In some embodiments, the material body includes shredded tobacco formed as a rod. The aerosol generating material may include tobacco material. The aerosol generating material may include extruded tobacco. The aerosol generating material may include reconstituted tobacco.

[0288] Aerosol-generating materials that form solid materials may include nicotine. Aerosol-generating materials may include tobacco, be composed of tobacco, or be substantially composed of tobacco. In this embodiment, the aerosol-generating material does not contain tobacco.

[0289] In any of the above embodiments, the heated article provides a relatively constant release of volatile compounds into the inhalable medium. In the above embodiments, the aerosol-generating section is a material plug. The article may include a mouthpiece. A tubular element may be located between the aerosol-generating material and the mouthpiece. The article may include a ventilated area in the mouthpiece. The mouthpiece may define a mouthpiece configured to be placed between the user's lips.

[0290] In any of the embodiments of the above-described articles, the resistive heating element is configured to heat substantially all of the aerosol-generating material. In an embodiment, the aerosol-generating section is at least substantially cylindrical. In an embodiment, the aerosol-generating section is at least partially enclosed by a resistive heating layer. In an embodiment, the resistive heating element extends within the aerosol-generating section. The resistive heating element may extend around the aerosol-generating section. In an embodiment, the resistive heating element surrounds the aerosol-generating section. In some arrangements, 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 an embodiment, first-type electrical contacts and second-type electrical contacts are exposed from the aerosol-generating section.

[0291] Aerosol-generating materials may include tobacco materials as described herein, which include tobacco components. In the tobacco materials described herein, the tobacco components may include paper-reconstituted tobacco. The tobacco components may also include tobacco leaves, extruded tobacco, and / or ribbon-cast tobacco. The tobacco material may be provided in the form of shredded tobacco. Shredded tobacco may be formed from a mixture of various forms of tobacco materials, such as one or more of paper-reconstituted tobacco, tobacco leaves, extruded tobacco, and ribbon-cast tobacco. In embodiments, the tobacco material includes paper-reconstituted tobacco or a mixture of paper-reconstituted tobacco and tobacco leaves. In the tobacco materials described herein, the tobacco material may include filler components. Filler components are generally non-tobacco components, that is, components that do not include tobacco-derived ingredients. Filler components may be non-tobacco fibers, such as wood fibers, pulp, or wheat fibers. Filler components may also be inorganic materials, such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, or magnesium carbonate. Filler components may also be non-tobacco casting materials or non-tobacco extrusion materials. The filler component may be present in an amount of 0 to 20% by weight of the tobacco material, or in an amount of 1% to 10% by weight of the composition. In some embodiments, the filler component is absent. The tobacco material described herein includes an aerosol-forming agent material. In this context, "aerosol-forming agent material" is an agent that promotes aerosol generation. Aerosol-forming agent materials can promote aerosol generation by promoting the initial evaporation and / or condensation of gases into inhalable solid and / or liquid aerosols. In some embodiments, the aerosol-forming agent material can improve the delivery of flavorings from the aerosol-generating material. Generally, any suitable aerosol-forming agent material or agent can be included in the aerosol-generating material of the present invention, including those aerosol-forming agent materials or agents described herein.

[0292] Paper-reconstituted tobacco refers to tobacco material formed through the following process: extracting tobacco raw materials with a solvent to provide a soluble extract and a residue including fibrous material, and then recombinating the extract (usually after concentration and optionally after further processing) with the fibrous material from the residue (usually after refining the fibrous material and optionally with the addition of a portion of non-tobacco fibers) by depositing the extract onto the fibrous material. The recombination process is similar to the papermaking process.
