[0134] The aerosol-generating film may have a thickness of approximately 0.015 mm to approximately 1 mm. For example, the thickness may be in the range of approximately 0.05 mm, 0.1 mm, or 0.15 mm to approximately 0.5 mm or 0.3 mm.

[0135] The aerosol-generating film may be continuous. For example, the film may contain continuous thin sheet material, or may consist of continuous thin sheet material.

[0136] The aerosol-generating film may be discontinuous. For example, the aerosol-generating film may include one or more separate parts or regions of the aerosol-generating material, such as dots, flakes, or lines, which may be supported by a support. In such embodiments, the support may be planar or non-planar.

[0137] The aerosol-generating film may be formed by combining an adhesive such as a gelling agent with one or more other components such as a solvent such as water, an aerosol-forming agent, and one or more substances to be delivered to form a slurry, and then heating the slurry to volatilize at least some of the solvent to form the aerosol-generating film.

In some embodiments, the support includes a susceptor. In some embodiments, the susceptor is embedded in the material. In some alternative embodiments, the susceptor is located on one or both sides of the material.

[0144] Consumables are articles containing or consisting of aerosol-generating material, which are intended to be consumed in part or in whole during use by the user. Consumables may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol-generating area, a housing, a roll of paper, a mouthpiece, a filter, and / or an aerosol modifier.

The heater may comprise, for example, a flammable material, a material that can be heated by electrical conductivity, or a susceptor.

[0145] An aerosol supply device may receive an article containing an aerosol-generating material for heating. In this context, “article” is a component containing or having an aerosol-generating material in use, which, when heated, volatilizes the aerosol-generating material in use and optionally other components. A user may insert an article into or onto the aerosol supply device, heat the article to generate an aerosol, and then inhale the aerosol.

[0146] An aerosol generator is a device configured to generate an aerosol from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol-generating material, thereby releasing one or more volatile substances from the material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from an aerosol-generating material without heating. For example, the aerosol generator may be configured to apply one or more of the following to the aerosol-generating material: vibration, rising pressure, or electrostatic energy.

[0147] Figure 1 is a block diagram of an aerosol generating device, shown as a whole by reference numeral 10, according to an exemplary embodiment.

[0148] The aerosol generation device 10 comprises a battery 11 (e.g., a rechargeable battery), a control circuit 12, and an aerosol generator 13. As will be 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 called an aerosol-generating material.

[0149] The resistance heater comprises at least one resistance heating element. The battery 11 acts as a power source. The control circuit acts as a controller and comprises a processor and memory. The control circuit is configured to implement the above method or each of the methods described later.

[0150] When using device 10, air is drawn into the air inlet of the aerosol generator 13, as indicated by arrow 16. The aerosol generated by the aerosol generator 13 exits the device through the air outlet (for example, into the mouth of the user of device 10), as indicated by arrow 17.

[0151] In some exemplary embodiments, the aerosol generating device 10 comprises two main components: a control section 2 (sometimes referred to as a reusable section) and consumables 4 (sometimes referred to as replaceable or disposable cartridges). When the aerosol generating device 10 is in use, the control section 2 and consumables 4 may be releasably connected at an interface 6. The consumables 4 may be removable and replaceable (for example, when the consumables are used), and the control section 2 may be reused with different consumables.

[0152] The aerosol generating device 10, including the aerosol generator 13, can be considered to together form an aerosol supply system comprising a control section 2, sometimes called an aerosol supply device, and consumables 4, sometimes called articles 4. The aerosol generating device 10 may also be referred to as the aerosol supply system in this specification.

[0153] The aerosol generator 13 forms part of article 4. The aerosol generator 13 includes a resistance heating component configured to generate an aerosol by heating at least one of an aerosol generating material, such as a membrane and / or a gel.

[0154] In the embodiments described above, or each heating element, is a resistance heating element, as will be described in detail below. In such a configuration, the system comprises a resistance heating generator which includes components for heating a heating component via a resistance heating process. In this case, an electric current is applied directly to the resistance heating element, and the resulting flow of current in the heating element acts as a heating component, heating the heating element by Joule heating. The resistance heating element includes a resistance material configured to generate heat when a suitable current passes through it, and the heating component includes electrical contacts for supplying current to the resistance material. By providing a resistance heating component, a compact configuration is possible. Resistance heating provides a space-efficient configuration.

[0155] A "section" is sometimes called a "part." A "part" is sometimes called a "section." Consumables are sometimes called replaceable or disposable items.

[0156] Naturally, the aerosol generating device 10 is provided only as an example and is highly schematic. Many alternative 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 in through an air inlet in the control section 2, passes through interface 6, and exits consumable 4.

[0157] The aerosol generator 13 is configured to generate an aerosol from an aerosol-generating material, also known as an aerosolizable material, during the operation of the aerosol supply system, as will be described in detail below. The aerosol supply system 10 is elongated and extends along its longitudinal axis. The aerosol supply system 10 has a proximal end 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 10, and a distal end that is furthest from the user during use. The proximal end is sometimes referred to as the “mouthpiece end.” The aerosol supply system 10 accordingly defines a proximal direction that is directed toward the user during use. Furthermore, the aerosol supply system 10 similarly defines a distal direction that is directed away from the user during use. The terms “proximal” and “distal” are explained by referring to the relative positioning of such features relative to each other in the proximal-distal direction along the longitudinal axis when applied to features of the system 10.

[0158] In this 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 within the longitudinal side wall of the aerosol supply device 10 and / or may be closed by another feature of the aerosol supply device 10 during use. In this configuration, article 4 defines a mouthpiece at its proximal end. In this embodiment, the aerosol supply device 10 defines a mouthpiece. During use, the user places their mouth over the mouthpiece.

[0159] Figure 2 is a block diagram of an aerosol generator, shown as a whole by reference numeral 20, according to an exemplary embodiment. The aerosol generator 20 is an exemplary implementation of the aerosol generator 13 of the aerosol generating device 10 described above.

[0160] The aerosol generator 20 comprises an aerosolizable layer 22 (incorporating an aerosolizable material) and a conductive layer 24 in contact with the aerosolizable layer. As will be described in detail below, the conductive layer 24 is formed on one or more heating elements, each heating element providing a conductive path for resistance 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. The conductive layer is also called the resistance heating layer.

[0161] The aerosolizable layer 22, also known as the aerosol-generating layer 22, contains an aerosolizable material also known as an aerosol-generating material.

[0162] The conductive layer 24 is formed as a resistive heating layer. The resistive heating layer contains a material that can be resistively heated in response to an electric current being passed through it.

[0163] The aerosol generator 20 includes a resistance heating layer 24. The 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 embodiments, the aerosol generating layer 22 is in indirect contact with the resistance heating layer 24. In embodiments, the resistance heating layer 24 may have a coating. The coating of the resistance heating layer 24 may be located on a conductive material.

[0164] The conductive layer 24 may take the form of a metal layer such as an aluminum layer, or a non-metallic material (such as graphene). The conductive layer may also take the form of a foil (for example, aluminum foil).

[0165] The aerosol generator 20 is configured to generate aerosols from aerosol-generating material when the aerosol supply system 10 is in operation, as will be described in detail below.

[0166] Figure 3 is a block diagram of an aerosol generator, shown as a whole by reference numeral 30, according to an exemplary embodiment. The aerosol generator 30 is an exemplary implementation of the aerosol generator 13 described above.

[0167] The aerosol generator 30 comprises the aerosolizable layer 22 and the conductive layer 24 described above. The aerosol generator 30 further comprises a support (or substrate) 32. The support 32 may include paper or cardboard material that provides structural support for the aerosol generator 30. As shown in Figure 3, in the aerosol generator 30, the conductive layer 24 is sandwiched between the support 32 and the aerosolizable layer 22.

[0168] In this embodiment, a conductive layer, also called a resistance heating layer 24, is located on the support 32. The support 32 is configured as a support layer. The support 32 has electrical insulating properties. The resistance heating layer 24 and the support layer 32 define the substrate. The substrate 32 supports the aerosol generation layer 22.

[0169] In the embodiment, the aerosol generator 30 comprises a laminate having a resistance heating layer 24 and a support layer 32. In the embodiment, the laminate comprises an aerosol generating layer 22. The aerosol generating layer 22 may be formed as a continuous structure or may be formed from individual parts. The individual parts may include one or more of dots, flakes, helices, or other shapes. In the embodiment, the individual parts are aligned with the resistance heating element.

[0170] One or more of the aerosol generating layer 22, the resistance heating layer 24, and the support layer 32 may comprise further layers. For example, the support layer 32 may comprise a backing layer or an intermediate layer. In this embodiment, the support layer 32 is omitted.

[0171] The above-described aerosol generators 30 are formed in a stacked configuration. In embodiments, other configurations such as tubular structures of articles are also conceivable. In such tubular structures, the aerosol generators 30 define a tubular configuration. The tubular shape may include circular or elliptical cross-sections and other polygonal shapes.

[0172] In this embodiment, as shown in the figure, the article 30 has a flat configuration. That is, the outside 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 also conceivable.

[0173] Figure 4 shows a heating element, collectively referred to as reference number 40, according to an exemplary embodiment. One or more heating elements 40 may be formed of the conductive layer 24 described above.

[0174] The heating element 40 has a non-linear conductive path between a first electrical connection 42 and a second electrical connector 43. In some exemplary embodiments, the first electrical connection 42 provides a positive connection and the second electrical connection 43 provides a negative connection, so that current flows between the electrical connections through this path. The winding or meandering nature of the path in the heating element 40 increases the overall length of the path between the first and second electrical connectors, and therefore increases the electrical resistance of the path (compared to a straight, direct path between the first and second electrical connectors).

[0175] The conductive path defines the resistive heating path. The resistive heating path is formed by the conductive path. The resistive heating path is nonlinear. The resistive heating path has a complex shape. The configuration of the resistive heating path may vary. The electrical resistance of the heating element 40 may depend on the properties of the resistive heating path in the conductive layer, such as the length, width, thickness, and configuration of the path. The electrical resistance of the resistive heating path may also depend on the material on which the resistive heating path is formed.

[0176] The first and second electrical connections may also be referred to as the first type of electrical contact 42 (or first type of electrical contact) and the second type of electrical contact 43 (or second type of electrical contact), respectively. The contact configuration may be reversed. The first and second types of electrical contacts define the heater electrical contact. The first and second types of electrical contacts 42, 43 form at least part of the article electrical contact configuration.

[0177] As will be discussed in detail below, the conduction path of the heating element 40 may be fabricated by forming tracks within the heating element, for example, by cutting tracks into the conductive layer constituting the heating element. In some exemplary embodiments, the tracks may have a width in the range of 0.5 mm to 1 mm (two exemplary prototypes have widths of 0.93 mm and 0.72 mm, respectively) and gaps 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 heating element may have overall dimensions of approximately 10 mm × 10 mm. Naturally, other dimensions are possible in other exemplary embodiments. By forming heating elements of these dimensions from aluminum foil with a thickness of 0.006 mm and an electrical resistivity of 2 to 6 μΩ cm, the resistance of the path is calculated to be approximately 1 Ω. In one exemplary embodiment, resistances of 0.83 to 1.31 Ω were measured.

[0178] The resistance heating layer comprises a plurality of resistance heating elements 40. The plurality of heating elements 40 are formed in an array as shown in Figure 5. The array of heating elements may be arranged in a single row. The array of heating elements may be arranged in a single row along the longitudinal axis of the aerosol generator. The array of heating elements may be arranged in a single row across the longitudinal axis of the aerosol generator. Other configurations are also conceivable.

[0179] The resistive heating element 40 comprises a first type of electrical track 44. The first type of electrical track 44 comprises a first type of electrical contact 42. The first type of electrical contact 42 is configured to electrically connect to a device electrical connector. The first type of electrical contact 42 includes a first type of exposed contact area. The first type of exposed contact area is exposed on the article to connect directly to the device electrical connector.

[0180] The resistive heating element 40 comprises a second type of electrical track 45. The second type of electrical track 45 comprises a second type of electrical contact 43. The second type of electrical contact 43 is configured to electrically connect to 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 to connect directly to the device electrical connector.

[0181] In embodiments, the conduction path of the heating element is created by defining at least one electrical insulation barrier within the resistive heating layer 24. In embodiments, the electrical insulation barrier is formed by cutting conductive limitations (i.e., electrical insulating portions), such as gaps, channels, or slots, into a thin sheet formed from a conductive material to form the resistive heating layer 24. In embodiments, the resistive heating layer 24 is pre-formed to define the above or each resistive heating element 40 and then attached to the support 32. In embodiments, the resistive heating layer 24 is attached to the support 32 and then the above or each resistive heating element 40 is defined in the resistive heating layer 24. The above or each resistive heating element 40 defining the resistive heating layer 24 may be a printed heater. At least one electrical insulation barrier defines first and second types of electrical tracks. The electrical insulation barrier defines a barrier to conductivity in this barrier.

[0182] The insulating barrier may be an air gap. In embodiments, the insulating barrier is a filled gap, which is filled with an insulating material, for example. The barrier defines a barrier to conductivity within this barrier.

[0183] The above-mentioned or each of the resistance heating elements 342 defining the resistance heating layer 340 may be formed by a cutting operation. The cutting may include die cutting. The resistance heating elements may be formed by an operation applied only to the resistance heating layer. In the embodiment, the resistance heating elements may be formed by an operation applied to the resistance heating layer and the support layer, for example, an operation to cut the resistance heating layer and the support layer.

[0184] Figure 5 shows a conductive layer, collectively referred to as reference numeral 50, according to an exemplary embodiment. The conductive layer 50 is an exemplary implementation of the heating element 24 of the aerosol generator 20 or 30 described above.

[0185] The conductive layer 50 is formed on a plurality of heating elements, indicated by reference numbers 51 to 55. Each of the heating elements 51 to 55 extends from a first type of electrical connection (connections 56a to 56e, respectively) to a second type of electrical connection (connection 58).

[0186] The number of electrical connections, sometimes called electrical contacts, may vary. Thus, each resistive heating element 51-55 extends between individual first-type electrical contacts 56a-56e and a common second-type electrical contact 58.

[0187] When layer 50 is used as a heating element 24 of the aerosol generator 20 or 30, each of the heating elements 51 to 55 provides a conductive path for resistance heating of a portion of the aerosolizable material of the support 22 to generate an aerosol in the respective portion of the support.

[0188] The first type of separate electrical connections 56a-56e allows current to be supplied individually to each of the multiple heating elements 51-55. Thus, heating of different sections of the aerosolizable material can be controlled. For example, the aerosol generator may have five aerosol generating sections. Layer 50 allows each of those sections to be activated separately. Thus, for example, five puffs of aerosol may be generated from a single consumable incorporating the heating elements 51-55.

[0189] Accordingly, for example, five puffs of aerosol may be produced from a single consumable incorporating a single aerosol generator 20 or 30, or ten puffs of aerosol may be produced from a single consumable incorporating two aerosol generators 20 or 30.

[0190] In the exemplary conductive layer 50, a first type of multiple electrical connections 56a-56e (e.g., positive electrical connections) are provided, and a second type of single connection 58 (e.g., negative electrical connection) is provided. This is not necessarily required for all implementations. For example, a second type of multiple connections may also be provided.

[0191] In this embodiment, each resistance heating element 51-55 comprises a corresponding first type electrical contact 42 and a corresponding second type electrical contact 43.

[0192] In the exemplary conductive layer 50, the first type of electrical connection is located at the first edge of the conductive layer, and the second type of electrical connection is located at the second edge of the conductive layer. This allows for convenient power connections, but of course many other configurations are possible, some of which will be discussed further below.

[0193] Figure 6 is a flowchart illustrating the algorithm, as a whole, as shown by reference no. 60, according to an exemplary embodiment. The algorithm 60 may be used to generate the aerosol generator 20 described above (for example, incorporating the conductive layer 50).

[0194] Algorithm 60 begins with operation 62, in which a conductive layer is formed on one or more heating elements (e.g., multiple heating elements), each heating element extending from a first type of electrical connection to a second type of electrical connection. When in use, the above or each heating element may be used to provide a conductive path for resistance heating of a portion of the aerosolizable material to generate an aerosol.

[0195] The formation of the above or each resistance heating element may be performed before or after attaching the resistance heating layer to the support, if a support is present. The resistance heating layer may be attached to the support, or attached to or formed on the support in a different configuration.

[0196] In operation 64, the formed conductive layer is brought into contact with the aerosolizable layer, and the aerosolizable layer incorporates the aerosolizable material.

[0197] In other words, in operation 64, at least one of the formed resistance heating layer and aerosol generating layer is brought into contact with other components, and the aerosol generating layer incorporates an aerosol generating material. In addition, or otherwise, the aerosol generating layer is formed on the resistance heating layer.

[0198] In operation 66, a control signal is applied to the selected heating element (i.e., one of the heating elements formed in operation 62). In one embodiment, the control signal can be used to cause the selected heating element to generate heat (generating an aerosol from the aerosolizable material, as discussed above). However, as will be discussed further below, the control signal applied in operation 66 may, in some embodiments, have a voltage exceeding the dielectric breakdown voltage of the heating element, and each heating element may be disabled in response to the control signal. In this way, the heating elements can be disabled after use. In some exemplary embodiments, a portion of the aerosolizable material may be made usable only once, and algorithm 60 allows the heating elements to be disabled after each portion of the aerosolizable material has been used.

[0199] Figure 7 is a flowchart illustrating the algorithm as a whole, as shown by reference no. 70, according to an exemplary embodiment.

[0200] Algorithm 70 begins with operation 72, in which one of several heating elements of the aerosol generator (such as aerosol generator 50 or 80 as described herein) is used. Then, in operation 72, a control signal is applied to the heating element used in operation 72. The control signal applied in operation 74 has a voltage exceeding the dielectric breakdown voltage of each heating element, and each heating element is disabled in response to the control signal. In this way, the used heating elements are disabled. Thus, operation 74 is an example of operation 66 as described above.

[0201] Figure 8 shows an aerosol generator, indicated collectively by reference numeral 80, formed according to an exemplary embodiment. The aerosol generator 80 comprises a conductive layer 82 and an aerosolizable layer 84 incorporating an aerosolizable material. The aerosolizable material may be formed on the layer 84, for example, by depositing the aerosolizable material, such as by spraying, coating, dispensing, or some other method.

[0202] The conductive layer 82 is formed on multiple heating elements in an exemplary implementation of operation 62 of the algorithm 60 described above. The conductive layer 82 may be, for example, the conductive layer 50 described above. Thus, the conductive layer 82 may comprise multiple heating elements, each of which comprises a nonlinear conductive path between a first electrical connection and a second electrical connection.

[0203] In an exemplary implementation of operation 64 of algorithm 60, the conductive layer 82 and the aerosolizable layer 84 are brought into contact with each other (indicated by arrow 86).

[0204] Each heating element in the conductive layer 82 has a dielectric breakdown voltage, and when this voltage is exceeded, the respective heating element is disabled in response to a control signal. After one of the heating elements in the conductive layer is used to generate an aerosol, the control signal may be applied to that heating element to implement the algorithm 70 described above (and one embodiment of operation 66 of algorithm 60).

[0205] Figure 9 is a block diagram of an aerosol generator 90 according to an exemplary embodiment. The aerosol generator 90 comprises one or more heating elements 92 (such as one or more of the heating elements described above) and a control circuit 94. The control circuit 94 may be used to generate control signals that are applied to the heating elements in operations 66 or 74 described above. For example, the control signals may be generated by the control circuit 94 after each heating element has been used. In some exemplary embodiments, the control circuit 94 may also generate heating control signals in an implementation of operation 72 of algorithm 70.

[0206] In some exemplary embodiments, the control circuit can query the heating element(s) to determine whether they are inoperable. This is shown by the dashed arrow in Figure 9.

[0207] Figure 10 is a block diagram of a system, shown as a whole by reference numeral 100, according to an exemplary embodiment. System 100 comprises an aerosol generator 102 (such as the aerosol generator 80 described above) and a control circuit 104. In common with control circuit 94, control circuit 104 may be used to generate control signals applied to the heating element of aerosol generator 102 in the operations 66 or 74 (and optionally operation 72 described above) described above. Thus, control signals may be generated after the use of each heating element. System 100 differs from aerosol generator 90 in that the control circuit 104 is provided separately from aerosol generator 102.

[0208] Figure 11 is a flowchart illustrating the algorithm, as a whole, as shown by reference numeral 110, according to an exemplary embodiment. The algorithm 110 may be implemented, for example, using the aerosol generator 80 or 90 or system 100 described above.

[0209] Algorithm 110 is initiated in an instance of operation 112 when a command to initiate heating is received. In response to the command to initiate heating, operation 113 queries one or more heating elements (e.g., a target heating element or any of several possible heating elements) to determine whether each heating element is operational or inoperable. For example, operation 113 may be used to determine whether each of the one or more heating elements has been rendered inoperable by the application of a suitable control signal.

[0210] Operation 114 determines whether a heating element is available. As discussed above, multiple heating elements may be provided. Operation 104 may also involve a determination of which of the heating elements (if any) is operational, which may be, for example, an indication of which of the heating elements has not yet been used (and therefore the corresponding available aerosolizable material has not yet been used).

[0211] If a heating element is available, the algorithm proceeds to operation 116, in which the available heating element is used. As discussed above, the heating elements may be individually controllable, for example, by supplying power to each individual heating element. After operation 116 is completed, the algorithm terminates in operation 118.

[0212] If operation 114 determines that a heating element is unavailable (for example, because all heating elements have been used), or that a specific target heating element is unavailable, the algorithm terminates in operation 118. This may mean that the consumables used to implement algorithm 110 need to be replaced.

[0213] Figure 12 shows a conductive layer 120 formed according to an exemplary embodiment. The conductive layer 120 is cut using a laser cutter 122. The cuts in the conductive layer 120 can be used to form paths for the heating elements described herein.

[0214] The use of the laser cutter 122 (or any other cutting process) is not the only way to produce the conductive layer described herein. Several exemplary methods are described below.

[0215] Figure 13 is a flowchart illustrating the algorithm, as a whole, as shown by reference no. 130, according to an exemplary embodiment.

[0216] Algorithm 130 begins with operation 132, in which a conductive layer is prepared. In operation 134, one or more heating elements are formed on the conductive layer by chemical etching. Operations 132 and 134 are exemplary implementations of operation 62 of algorithm 60 described above.

[0217] In operation 136 of algorithm 130, the conductive layer is brought into contact with the aerosolizable layer. Therefore, operation 136 is an example of operation 64 described above.

[0218] The flowchart in Figure 13 may also be referenced as illustrating a part of a method or algorithm for forming aerosol generators 20, 30, and 80. In embodiments, the method or algorithm 130 begins with operation 132, in which a resistance heating layer is prepared. In operation 134, one or more resistance heating elements are formed on the resistance heating layer by chemical etching of the resistance heating layer. Operations 132 and 134 are exemplary implementations of operation 62 of the method 60 described above. Operation 64 is then implemented by placing the aerosol generating material on the resistance heating layer.

[0219] Figure 14 is a flowchart illustrating the algorithm as a whole, as shown by reference no. 140, according to an exemplary embodiment.

[0220] Algorithm 140 begins with operation 142, in which a heating element is formed by printing a conductive layer at least partially. Thus, operation 142 is an exemplary implementation of operation 62 of algorithm 62 described above. In operation 144 of algorithm 140, the conductive layer is brought into contact with the aerosolizable layer. Thus, operation 144 is an example of operation 64 described above.

[0221] The flowchart in Figure 14 may also be referenced as showing a method for forming aerosol generators 20, 30, and 80, or a part of the algorithm as a whole indicated by reference no. 140. The method or algorithm 140 begins with operation 142, in which one or more heating elements are formed by printing a resistance heating layer at least partially. Thus, operation 142 is an exemplary implementation of operation 62 of algorithm 60 described above. Operation 64 described above is then implemented by placing the aerosol generating material on the resistance heating layer.

[0222] The cutting, etching, and printing methods described above are provided as examples, and alternative methods are also possible. For example, the so-called "hot foiling" technique can be used, in which a heating element is made from a conductive layer and then assembled / bonded to the substrate. Further techniques, such as die cutting, can also be used. In addition, two or more techniques can be combined (for example, conductivity can be added to connection traces by adding more conductive materials such as additional foil or printing materials). Many further techniques or combinations of techniques that can be used in implementing the principles described herein will be recognized by those skilled in the art.

[0223] In the exemplary embodiments described above, the heating element(s) include a non-linear conductive path (e.g., a winding path) between the first electrical connections 42, 56 and the second electrical connectors 43, 58. This is not necessarily required in all exemplary embodiments. Several alternative configurations are described below as examples.

[0224] Figure 15 shows a conductive layer, collectively referred to as reference number 150, according to an exemplary embodiment. The conductive layer 150 may be formed using the laser cutter 122 described above or some similar device.

[0225] The conductive layer 150 comprises multiple heating elements, each heating element being a linear heating element with a conduction path extending along the length of the support. Each heating element extends from a first type of electrical connection (e.g., a positive electrical connection) to a second type of electrical connection (e.g., a negative electrical connection). In the exemplary layer 130, both types of electrical connections are located at the same end of the layer and adjacent to one another. Thus, instead of a winding path, the exemplary path of layer 130 extends from one end of the layer to the other and back. Note that there is no common second connection as in some other exemplary embodiments, but each heating element has distinct first and second electrical connections.

[0226] Figure 16 shows a conductive layer, collectively referred to as reference number 160, according to an exemplary embodiment. The conductive layer 160 may be formed using the laser cutter 122 described above, or some similar device.

[0227] In other words, the resistance heating layer 160 may be formed using the laser cutter 122 described above, or some similar device or other method. Each resistance heating element extends from one of the first type of electrical contacts, for example, a positive electrical contact, to a second type of electrical contact, for example, a negative electrical contact.

[0228] The conductive layer 160 comprises multiple heating elements, each heating element being a linear heating element with a conduction path extending along the length of the support. Each heating element extends from a first type of electrical connection (e.g., a positive electrical connection) to a second type of electrical connection (e.g., a negative electrical connection). In the exemplary layer 140, these types of electrical connections are provided at both ends of the layer, and a common second (negative) connection is provided. Although linear paths (not winding paths) are provided, electrical resistance is provided by providing sawtooth-shaped paths. Note that the paths in any other embodiments described herein may also be sawtooth-shaped.

[0229] Figure 17 shows a portion of an aerosol generator 170 according to an exemplary embodiment. As discussed above, the aerosol generator 170 may comprise a conductive layer having a first type of multiple electrical connections (e.g., providing a positive electrical connection to each of the multiple heating elements) and a second type of single electrical connection (e.g., providing a common negative electrical connection to the multiple heating elements). The aerosol generator 170 is part of Article 300.

[0230] In other words, article 300 has an article electrical contact configuration. This electrical contact configuration is formed by an aerosol generator 170 in an embodiment. This electrical contact configuration includes heater electrical contacts 172, 174. The heater electrical contacts may also be called heater or article contacts 172, 174. The aerosol supply device includes an electrical connector 180, as shown in Figure 18. This electrical connector includes connector electrical contacts. The connector electrical contacts may also be called connector or device contacts. The article electrical contact configuration is configured to communicate electrically with the device electrical connector 180.

[0231] The first and second types of electrical contacts 42, 43, i.e., heater contacts, together form at least a portion of the article electrical contact configuration of the aerosol generators 20, 30, and 80.

[0232] The resistive heating element 40 is located inside the conductive layer 82. The conductive layer is the resistive heating layer. The inside defines the first side of the aerosol generator 170. The heater contacts 42 and 43 are located on the second side of the resistive heating layer 82. The second side defines the outside of the aerosol generator 170. The heater contacts are exposed and therefore can contact the device electrical connector. The heater contacts are located on the opposite side of the resistive heating element from the resistive heating layer 82. Other configurations are also possible.

[0233] The support layer 32 is located between the inner portion and the outer portion of the resistance heating layer 82.

[0234] The aerosol generator 170 is equipped with multiple external connectors, the configuration of which depends on the configuration of the first and second types of electrical connections of the aerosol generator. For example, the aerosol generator shown in Figure 17 is equipped with multiple external connectors indicated by reference numeral 172 (each connected to one of the first type of electrical connections) and a further external connector 174 (connected to the second type of electrical connection). The aerosol generator 170 may have further external connectors corresponding to connectors 172 and 174 located on the underside of the device (not visible in Figure 17).

[0235] Figure 18 shows a connector 180 used in some exemplary embodiments. This connector has separate pins for connecting to electrical contacts such as the connectors 172 and 174 described above.

[0236] The configuration of article 300 may vary. Article 300 comprises a body 302. The body 302 may be hollow. The body 302 may define a flow path through article 300. The flow path extends between an air inlet and an aerosol outlet. The flow path is defined by an internal space within the article through which air and / or aerosol can flow. The flow path is defined within the body 302. The above or each aerosol generator 170 connects the flow path. The aerosol generating material is exposed in the flow path. The aerosol generating material is exposed in the internal space. In embodiments, the internal space comprises two or more chambers.

[0237] Figure 17 shows the aerosol generator 170 and the distal end of article 300. As shown, the body 302 comprises a plurality of body layers. The body layers are arranged in a stack of body layers 304. The body layers form a laminate. In embodiments, the body layers are cardboard layers. Other suitable materials may be used. The body layers 304 are configured to define the features of article 300. In embodiments, at least one body layer has a gap that defines an air inlet. The gap defines an opening 306.

[0238] The air inlet includes an opening 306. The opening is formed within the main body 302. In the embodiment, the opening 306 is formed in another component of the article 300, for example, the aerosol generator 170 or another wall feature. The aerosol outlet includes an outlet opening. The outlet opening is formed within the main body 302. In the embodiment, the outlet opening is formed in another component of the article 300, for example, the aerosol generator 170 or another wall feature.

[0239] In an embodiment, article 300 may comprise two aerosol generators 170 that form an aerosol generator configuration. The number of aerosol generators 170 may vary. Each aerosol generator 170 comprises an aerosol generating material. The aerosol generating material is exposed in the flow path. In an embodiment, article 300 comprises a single aerosol generator 170.

[0240] Figure 19 is a block diagram of an aerosol generating device, shown as a whole by reference numeral 190, according to an exemplary embodiment. The system comprises the aerosol generator 170 described above, a first connector 180a and a second connector 180b (similar to the connector 180 described above), and a control section 192.

[0241] The aerosol generation device 190 is also known as the aerosol supply system 190.

[0242] The control section 192 is similar to the control section 2 of the aerosol generating device 10 described above with reference to Figure 1. The aerosol generator 170 is similar to the consumable 4 of the aerosol generating device 10. Connectors 180a and 180b enable the control section 192 to provide regulated or controlled voltage and / or current to various first and second types of electrical connections of the aerosol generator 170 when the aerosol generator 170 is inserted into the control section 192 (as shown in Figure 19). The control section 192 may implement, for example, the algorithm 110 described above.

[0243] In this embodiment, article 300 may be received by an aerosol supply device 190. The configurations of article 300 and the aerosol supply device 190 may vary.

[0244] Figures 20 and 21 show a heating element 200 according to an exemplary embodiment. The heating element 200 may be formed by a conductive layer (such as layer 24 described above).

[0245] The heating element 200 has a plurality of nonlinear conductive paths between the first electrical connection 42 and the second electrical connector 43, and is therefore similar to the heating element 40 described above. The heating element 200 differs from the heating element 40 in that portion 202 of the conductive path is narrowed.

[0246] The heating element 200 can be used to implement operation 66 of algorithm 60 or operation 74 of algorithm 70 described above. Figure 20 shows the heating element before operation 66 or 74 (indicated as 200a). Figure 21 shows the heating element after operation 66 or 74 (indicated as 200b).

[0247] In operations 66 and 74, a control signal is applied to the heating element 200. As discussed above, the control signal (for example, in the first operating mode) has a voltage exceeding the dielectric breakdown voltage of the heating element, and in response to the control signal, each heating element is rendered inoperable. Figure 21 shows the dielectric breakdown portion 212 of the heating conductive path (the location of the narrow portion 202 shown in Figure 20).

[0248] By providing a narrow section 202, it becomes possible to control where the heating element undergoes dielectric breakdown. Dielectric breakdown may be controlled in some way by the degree to which the path is narrowed (for example, by controlling the voltage and / or current levels at the location where dielectric breakdown occurs).

[0249] The narrow portion acts as a fuse portion. Another feature may be used in place of, or in combination with, the narrow portion 202 to act as a fuse portion. The fuse portion may include at least one hole, perforation, score mark, or channel within the conductive layer. The fuse portion may extend at least partially in the thickness direction of the conductive layer. The fuse portion may extend completely in the thickness direction of the conductive layer. The fuse portion may extend partially in the width direction of the path of the heating element. The fuse portion may have a portion with reduced width within the path of the heating element.

[0250] The fuse portion has a dielectric breakdown voltage, and when a control signal with a voltage exceeding the dielectric breakdown voltage is applied, the fuse portion breaks or ruptures. When the fuse portion breaks, the heating element 200 is rendered inoperable. When the control signal is applied, the electrical connection between the heating element 200 and the first electrical connection 42 is broken.

[0251] Each heating element 200 may have its own fuse portion. Each fuse portion of the heating element may have the same dielectric breakdown voltage or different dielectric breakdown voltages.

In embodiments, the aerosol-generating material is in the form of an aerosol-generating segment. The aerosol-generating segment generally comprises a solid material.

For example, the aerosol-generating material arranged as an aerosol-generating segment may comprise a plurality of individual aerosol-generating material pieces. The aerosol-generating material may also comprise individual cigarette material pieces. In embodiments, the aerosol-generating material comprises a plurality of fragments, beads, or pellets. In embodiments, the aerosol-generating segment is a material plug.

[0253] In some embodiments, the aerosol-generating segment includes a material body. The aerosol-generating material is non-liquid. In such embodiments, the material body constitutes a rod of the aerosol-generating material, for example, a tobacco rod. For example, the material body may include shredded tobacco material. The material body may be formed into a rod. In some embodiments, the material body includes shredded rag tobacco formed into a rod. The aerosol-generating material may include tobacco material. The aerosol-generating material may include extruded tobacco. The aerosol-generating material may include recycled tobacco.

[0254] The aerosol-generating material, formed as a solid material, may contain nicotine. The aerosol-generating material may contain tobacco, consist of tobacco, or consist essentially of tobacco. In the embodiment, the aerosol-generating material does not contain tobacco.

[0255] In any of the embodiments described above, heating the article provides a relatively constant release of volatile compounds into an inhalable medium. In one embodiment described above, the aerosol-generating segment is a material plug. The article may comprise a mouthpiece end section. A tubular element may be located between the aerosol-generating material and the mouthpiece end section. The article may comprise a ventilation area within the mouthpiece end section. The mouthpiece end section may define a mouthpiece configured to be positioned between the user's lips.

The aerosol-generating segment is, in embodiments, at least substantially cylindrical. In embodiments, the aerosol-generating segment is at least partially wrapped by a resistance heating layer. In embodiments, the resistance heating element extends into the aerosol-generating segment. The resistance heating element may extend around the aerosol-generating segment. In embodiments, the resistance heating element surrounds the aerosol-generating segment. In some configurations, at least a portion of the flow path through the article passes through the aerosol-generating segment. The aerosol-generating segment may define a portion of the air path. In embodiments, a first type of electrical contact and a second type of electrical contact are exposed from the aerosol-generating segment.

[0257] The aerosol-generating material may include the tobacco material described herein, and the tobacco material contains tobacco components. In the tobacco material described herein, the tobacco components may include recycled tobacco. The tobacco components may also include loose tobacco, extruded tobacco, and / or band-cast tobacco.

In embodiments, the tobacco material includes recycled tobacco, or a mixture of recycled tobacco and loose tobacco. In the tobacco material described herein, the tobacco material may contain filler components. The filler components are generally non-tobacco components, i.e., components that do not contain tobacco-derived raw materials. The filler components may be non-tobacco fibers such as wood fibers or pulp or wheat fibers. The filler components may also be inorganic materials such as chalk, perlite, vermiculite, diatomaceous earth, colloidal silica, magnesium oxide, magnesium sulfate, and magnesium carbonate. The filler component may also be a non-tobacco cast material or a non-tobacco extruded material. 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. In the tobacco materials described herein, the tobacco material contains an aerosol-forming material. In this context, “aerosol-forming material” is an active substance that promotes aerosol formation. The aerosol-forming material can promote aerosol formation by promoting initial vaporization and / or condensation from gas to inhalable solid and / or liquid aerosols. In some embodiments, the aerosol-forming material can improve the delivery of flavor from the aerosol-forming material. Generally, any suitable aerosol-forming material or active substance, including those described herein, may be included in the aerosol-forming material of the present invention.

[0258] Recycled tobacco refers to tobacco material formed by a process in which tobacco raw materials are extracted with a solvent to yield an extract of residue containing soluble substances and fibrous materials, and then the extract (usually concentrated and optionally further processed) is recombined with fibrous materials from the residue (usually purified and optionally with some non-tobacco fibers added) through deposition of the extract onto the fibrous material. This recombination process is similar to the papermaking process.
