Description

Technical Field

[0001] This invention relates to an aerosol supply device. The invention also relates to an article for use with the aerosol supply device, an aerosol supply system, and a method of operating the aerosol supply device. Background Technology

[0002] Smoking products such as cigarettes and cigars burn tobacco during use to produce tobacco smoke. Efforts have been made to provide alternatives to these products by developing products that release compounds without combustion. Examples of such products are so-called "heat-not-burn" products or tobacco heating devices or products that release compounds by heating rather than burning materials. The material can be, for example, tobacco or other non-tobacco products, which may or may not contain nicotine.

[0003] Aerosol supply systems encompassing the aforementioned devices or products are known. Common systems utilize a heater to generate an aerosol from a suitable medium, which is then inhaled by the user. Typically, the medium used needs to be replaced or changed to provide different aerosols for inhalation. It is known to use resistance heating systems as heaters to generate an aerosol from a suitable medium. Summary of the Invention

[0004] According to a first aspect, an aerosol supply device is provided, comprising: The article receiving section is shaped to receive articles during use, the articles comprising: Aerosol generating materials; and At least one resistive element, including a first electrical contact and a second electrical contact, is used to achieve electrical connection of the resistive element; An electrical connector includes a plurality of connector electrical contacts configured to engage with corresponding electrical contacts in a first and second electrical contact of a resistive element; and The control system is configured as follows: During use, the electrical characteristics between the first and second electrical contacts of the resistive element are determined; and The operation of the aerosol supply device is controlled based on the determined electrical characteristics.

[0005] The first and second electrical contacts of a resistive element can be considered as the electrical contacts of the product.

[0006] Electrical properties can include current. Determining current can include measuring current.

[0007] The control system can be configured as follows: A fixed voltage is applied across the first and second electrical contacts of the resistive element; and Measure the current flowing through the first and second electrical contacts of the resistive element.

[0008] Electrical characteristics can include voltage drop. Determining voltage drop can include measuring voltage drop.

[0009] The control system can be configured as follows: A fixed current is applied through the first and second electrical contacts of the resistive element; and Measure the voltage drop across the first and second electrical contacts of the resistive element.

[0010] Electrical characteristics may include resistance. Resistance may be determined based on a defined current and / or voltage drop between the first electrical contact and the second electrical contact.

[0011] The control system can be configured as follows: A fixed voltage is applied across the first and second electrical contacts of the resistive element; Measure the current flowing through the first and second electrical contacts of the resistive element; and The resistance between the first and second electrical contacts of the resistive element is determined based on the measured current.

[0012] The control system can be configured as follows: A fixed current is applied through the first and second electrical contacts of the resistive element; Measure the voltage drop across the first and second electrical contacts of the resistive element; and The resistance between the first and second electrical contacts of the resistive element is determined based on the measured voltage drop.

[0013] In any of the above embodiments, the resistance can be determined using Ohm's law, that is, the resistance equals the voltage divided by the current.

[0014] At least one resistive element may include a resistive heating element that forms part of a heating device arranged to heat the aerosol-generating material.

[0015] The resistance of a resistance heating element can be related to its position within the article, and the control system can be configured to control the power supply to the resistance heating element based on its position within the article. Therefore, resistance can affect the determined electrical characteristics, and thus the determination of these electrical characteristics can allow for the determination of the position of the resistance heating element within the article.

[0016] The control system can be configured to measure the current between the first and second electrical contacts of the resistive element and determine the resistance based on the measured current.

[0017] The control system can be configured to compare the determined electrical characteristics with one or more thresholds and control the aerosol supply device based on the comparison results. For example, the control system can be configured to prevent the device from operating when the determined electrical characteristics are below a first threshold and / or above a second threshold.

[0018] The control system can be configured to determine whether a determined electrical characteristic (e.g., resistance and / or voltage drop and / or current) falls within a first operating range defined between a first threshold (e.g., a lower threshold) and a second threshold (e.g., an upper threshold), and the control system can be configured to prevent use of the device when the determined electrical characteristic is outside the first operating range. The control system can also be configured to allow use of the device (e.g., allow the device to operate) when the electrical characteristic is determined to fall within the first operating range. The first and second thresholds of the range may or may not include the endpoints of the first operating range.

[0019] The control system can be configured to determine whether an electrical characteristic falls within a second operating range defined between a third threshold and a fourth threshold, wherein the second operating range is completely contained within a first operating range, and wherein the control system is configured to indicate that the device and / or article requires maintenance when the determined electrical characteristic is within the first operating range but outside the second operating range. The third threshold may be greater than the first threshold, and the fourth threshold may be greater than the third threshold but less than the second threshold. The device can be configured to operate normally when the determined electrical characteristic falls within the second operating range. The third and fourth thresholds may or may not include the endpoints of the second operating range.

[0020] One or more thresholds (e.g., one or more of a first threshold, a second threshold, a third threshold, or a fourth threshold, which may define a second operating range and / or a first operating range) may be predetermined (e.g., fixed).

[0021] One or more thresholds (e.g., one or more of a first threshold, a second threshold, a third threshold, or a fourth threshold, which may define a second operating range and / or a first operating range) may be set during use of the device (e.g., the thresholds may be dynamic).

[0022] One or more thresholds (e.g., one or more of a first threshold, a second threshold, a third threshold, or a fourth threshold, which may define a second range and / or a first range) may be set based on (e.g., depending on) the characteristics of the device (e.g., the current temperature of the device).

[0023] In any of the above embodiments, one or more thresholds may represent threshold resistance, current, or voltage (e.g., voltage drop), and electrical characteristics may accordingly include resistance, current, or voltage drop.

[0024] The control system can be configured to change the voltage applied across the first and second electrical contacts of the resistive element based on determined electrical characteristics. The control system can change the voltage applied across the first and second electrical contacts to obtain a target current (e.g., a predetermined current) flowing between the first and second electrical contacts of the resistive element.

[0025] The control system can be configured to increase or decrease the voltage applied across the first and second electrical contacts of the resistive element based on determined electrical characteristics (e.g., proportional to them), thereby maintaining a predetermined current between the first and second electrical contacts of the resistive element.

[0026] The control system can be configured to identify the type of article inserted into the cavity based on the determined electrical characteristics.

[0027] The control system can be configured to determine the insertion of an article (e.g., determining full insertion of the article) based on electrical characteristics. For example, detecting an electrical characteristic such as non-zero current or non-infinite resistance can indicate that a circuit has been established between multiple connector electrical contacts that have engaged with corresponding electrical contacts in the first and second electrical contacts of the resistive element. Determining insertion (e.g., determining full insertion) allows the control system to appropriately control the operation of the device. For example, it can allow the control system to supply power to at least one resistive heating element, which in some embodiments can result in the generation of an aerosol. In some embodiments, the control system can be configured to determine the removal of an article (e.g., complete removal) based on electrical characteristics. For example, detecting a specific electrical characteristic such as zero current or infinite resistance can indicate that the connector electrical contacts are no longer electrically connected to the first and second article electrical contacts, which can indicate that the article has been removed. The control system can then control the operation of the device based on this determination. For example, when it is determined that the article has been removed, the control system can cut off the power supply to the connector electrical contacts.

[0116] The aerosol-generating material can be an "amorphous solid." In some embodiments, the amorphous solid is a "monolithic solid." The aerosol-generating material can be non-fibrous or fibrous. In some embodiments, the aerosol-generating material can be a dried gel. The aerosol-generating material can be a solid material capable of retaining some fluid (such as a liquid) within it. In some embodiments, the retained fluid can be water (such as water absorbed from the surroundings of the aerosol-generating material), or it can be a solvent (such as when the aerosol-generating material is formed from a slurry). In some embodiments, the solvent can be water.

[0117] Aerosol forming agent materials may include one or more components capable of forming aerosols. In some embodiments, aerosol forming agent materials may include one or more of glycerol, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butanediol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl octanoate, triethyl citrate, triacetin, a mixture of glycerol diacetate, benzyl benzoate, benzyl phenyl acetate, glyceryl tribocate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0119] The material may be present on or within the support to form a matrix. The support may be, or include, for example, paper, cardboard, paperboard, reconstituted materials, plastic materials, ceramic materials, composite materials, glass, metal, or metal alloys.

[0120] An aerosol supply device can receive an article comprising aerosol-generating material for heating. As used herein, an "article" is a component that includes or contains aerosol-generating material in use, is heated to atomize the aerosol-generating material, and optionally includes or has other components in use. A user can insert the article into or onto an aerosol supply device and then heat the article to generate an aerosol, which the user subsequently inhales.

[0121] An aerosol generator is a device configured to generate aerosols from aerosol-generating materials. In some embodiments, an aerosol generator is a heater configured to subject aerosol-generating materials to thermal energy, causing the aerosol-generating materials to release one or more volatiles to form an aerosol.

[0122] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transport component, an aerosol transport component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may include a conductor capable of being heated by an electric current flowing through it.

[0123] Non-combustible aerosol supply systems may include modular components comprising both a reusable aerosol supply device and a replaceable aerosol generating article. In some implementations, the non-combustible aerosol supply device may include a power source and a controller (or control circuitry). The power source may include, for example, a power source such as a battery or rechargeable battery. In some implementations, the non-combustible aerosol supply device may also include an aerosol generating component. However, in other implementations, the aerosol generating article may partially or completely comprise the aerosol generating component.

[0124] Figure 1 A schematic diagram of an aerosol supply system 100 is shown. The aerosol supply system 100 includes an aerosol supply device 200 and an article 300, which includes an aerosol generating material 302 (see reference). Figure 3 ). 300 products in Figure 2 The image shows the product being removed from the aerosol supply device 200. The aerosol generator 304 of the article 300 is in... Figure 3 The first side 306 is shown in a perspective view, and in Figure 4 A perspective view of a portion of the second side 307 is shown in the middle.

[0125] Article 300 includes an aerosol generator 304. The aerosol generator 304 is configured to generate aerosols from the aerosol generating material 302 during operation of the aerosol supply system 100, as will be described in detail below.

[0126] The aerosol supply system 100 may be elongated, extending along a longitudinal axis. The aerosol supply system 100 has a proximal end 102 that is closest to the user (e.g., closest to the user's mouth) when the user inhales the aerosol generated by the aerosol supply system 100, and a distal end 104 that is furthest from the user during use.

[0127] The proximal end can also be referred to as the "mouth end". Therefore, the aerosol supply system 100 is defined in a proximal direction toward the user during use. In addition, the aerosol supply system 100 is also defined in a distal direction away from the user during use. The terms "proximal" and "distal" when applied to features of the system 100 will be described by referring to the relative positioning of these features with respect to each other in the proximal-distal direction along the longitudinal axis.

[0128] Article 300 is received by aerosol supply device 200. The configurations of article 300 and aerosol supply device 200 can vary. In this embodiment, aerosol supply device 200 includes a device body 202. Device 200 has a housing 204 surrounding the various components of the device. Figure 5 As shown, a product receiving portion 206 (sometimes referred to as a device chamber) is configured to receive a portion of a product 300. When the product 300 is received in the device chamber 206, the proximal end 308 of the product extends from the device 200. The receiving portion 208 defines the chamber 206. The receiving portion 208 includes a receiving portion bottom 210 and a receiving portion outer peripheral wall 212. The configuration of the receiving portion 208 can vary depending on the configuration of the product 300.

[0129] One or more user-operable control elements 224, such as buttons or switches, can be provided on the aerosol supply device 200 for operating the aerosol supply system 100. For example, a user can start the system 100 by pressing the control element 224. One or more user-operable control elements may be omitted. In some embodiments, the aerosol supply system 100 is operated by other user actions, such as "intake" initiated by a user drawing air through the system.

[0130] The aerosol supply device 200 includes an opening 214 at its proximal end that leads into a device chamber 206. The opening 214 is disposed in one end through which an article 300 can be inserted. In some embodiments, the article 300 can be fully or partially inserted into the device 200. The configuration of the device 200 can vary; for example, the opening may be located in a longitudinal sidewall of the device 200, and / or the opening may be closed during use by another feature of the device 200. In the configuration of the invention, the article 300 defines a suction nozzle 310 located at its proximal end 308. In other embodiments, the device 200 defines this suction nozzle. During use, the user places their mouth over the suction nozzle.

[0131] Device 200 defines a longitudinal axis along which article 300 can extend when inserted into device 200. Opening 214 is aligned on the longitudinal axis. The longitudinal axis can be the axis along which article 300 is inserted into device 200. The longitudinal axis can be considered as the receiving axis of device 200. Article 300 can similarly have a longitudinal axis along which it is inserted into the device, and this axis can be considered as the insertion axis.

[0132] The aerosol supply device 200 includes a power source 220. The power source 220 may be a battery, such as a rechargeable battery. The device 200 also includes control circuitry 222, which functions as a controller and includes a processor and memory.

[0133] As discussed in detail below, the heating system 110 is configured to heat the aerosol-generating material 302 of the article 300. In some embodiments, the article 300 is consumable and interchangeable with other articles 300. The heating system 110 includes an aerosol generator 304. The heating system 110 includes other components of the aerosol supply system 100, including components of the article 300 and the aerosol supply device 200, such as the power source 220 and control circuitry 222.

[0134] Aerosol generator 304 forms part of article 300. Aerosol generator 304 includes heating device 312 configured to heat aerosol generating material 302 (e.g., to heat at least one of a membrane and a gel) to generate an aerosol. Aerosol generating material may be referred to as aerosolizable material.

[0135] The heating device 312 is a resistance heating device. In some embodiments, the heating element, or each heating element, is a resistance heating element, as described in detail below. In this configuration, the heating system 110 includes a resistance heating generator, which includes components for heating the heating device 312 through a resistance heating process. In this case, current is applied directly to the resistance heating element, and the flow of current in the heating element, which acts as the heating component, causes the heating element to be heated by Joule heating. The resistance heating element comprises a resistive material configured to generate heat when a suitable current flows through the resistive material, and the heating device 312 includes electrical contacts for supplying current to the resistive material. The arrangement of the resistance heating device 312 achieves a compact device. Resistance heating achieves a highly efficient configuration.

[0136] When using the aerosol supply system 100, air is drawn into the air inlet 314 of the article 300, as indicated by arrow 316. The air inlet 314 is located at the distal end of the article 300. In some embodiments, the air inlet 314 may have different configurations, for example, the air inlet may be located on the side. The airflow to the air inlet 314 of the article 300 may be defined, for example, by at least one of an air path through the device 200, an air path located outside the device 200, and an air path between the device 200 and the article 300. The aerosol generated by the aerosol generator 304 exits the device at the aerosol outlet 318, as indicated by arrow 319. In some embodiments, the aerosol outlet 318 is located in the mouthpiece of the article 300, such that the aerosol can be drawn directly from the article 300 into the mouth of the user of the system 100.

[0137] In some exemplary embodiments, the aerosol supply system includes two main components: a control section forming a reusable portion and a consumable section forming a replaceable or disposable portion, which may also be referred to as a replaceable or disposable product or atomizing cartridge. As described herein, the aerosol supply device 200 forms the control section, and the product 300 forms the consumable section. When using the aerosol generation system, the control section and the consumable portion can be releasably connected at an interface. The consumable portion can be removable and replaceable; for example, when the consumable portion is used up, the control section can be reused along with a different consumable portion.

[0138] The aerosol supply system 100 shown is provided by way of example only and is highly illustrative. Different aerosol generating devices and other means may be used in exemplary implementations of the principles described herein. For example, in some exemplary embodiments, air is drawn into an air inlet in a control section, passes through an interface, and then exits the consumable portion.

[0139] like Figure 5 As schematically shown and as described in detail below, article 300 has an article electrical contact configuration 320. In some embodiments, the electrical contact configuration 320 is constituted by an aerosol generator 304. The electrical contact configuration 320 includes a heater electrical contact 322. The heater electrical contact 322 may also be referred to as a heater or an article contact. The aerosol supply device 200 includes an electrical connector 230. The electrical connector 230 includes a connector electrical contact 232. The connector electrical contact 232 may also be referred to as a connector or a device contact. The article electrical contact configuration 320 is configured to be in electrical communication with the device electrical connector 230.

[0140] The configuration of article 300 can be varied. Article 300 includes a body 324. Body 324 is hollow. Body 324 defines a flow path 326 through article 300 (see reference). Figure 6 Flow path 326 extends between air inlet 314 and aerosol outlet 318. Flow path 326 is defined by an internal space within the article along which air and / or aerosol can flow. Flow path 326 is defined within body 324. The aerosol generator or each aerosol generator 304 defines flow path 326. Aerosol generating material 302 is exposed to flow path 326. Aerosol generating material 302 is exposed to the internal space. In some embodiments, the internal space comprises two or more chambers.

[0141] Air inlet 314 includes an opening 315. Opening 315 is formed in body 324. In some embodiments, the opening is formed in another component of article 300, such as in aerosol generator 304 or another wall feature. Aerosol outlet 318 includes an outlet opening 317. Outlet opening 317 is formed in body 324. In some embodiments, outlet opening 317 is formed in another component of article 300, such as in aerosol generator 304 or another wall feature.

[0142] like Figure 6 As shown, article 300 includes two aerosol generators 304 to form an aerosol generator configuration. The number of aerosol generators 304 may vary. Each aerosol generator 304 includes an aerosol generating material 302. The aerosol generating material 302 is exposed to a flow path 326. In some embodiments, article 300 includes a single aerosol generator 304. One aerosol generator 304 will be described in detail below, and these details also apply to one or more other aerosol generators 304 in some embodiments.

[0143] The aerosol generator, or each aerosol generator 304 and body 324, is formed in a stacked configuration. In some embodiments, other configurations are contemplated, such as the article being tubular. In such a tubular configuration, the aerosol generator 304 defines a tubular shape. This tubular shape may include a circular cross-section, an elliptical cross-section, and other polygonal shapes.

[0144] In some embodiments, as shown in the accompanying drawings, the article 300 has a planar configuration. That is, the exterior of the article has a length, a width perpendicular to the length, and a depth perpendicular to each of the length and the width, wherein the length is greater than or equal to the width, and wherein the width is greater than the depth. Other configurations are also conceivable.

[0145] Figure 6 This is a partially exploded perspective view of article 300, in which aerosol generator 304 is shown flipped relative to the assembly orientation and spaced apart from other components. Article 300 includes a first aerosol generator 302, a body 324, and a second aerosol generator. The body 324 spaces the first aerosol generator and the second aerosol generator 304 apart. The first aerosol generator and the second aerosol generator 304 enclose an internal space defined by the body 324, along which air and / or aerosol can flow. The aerosol generating materials 302 of the first aerosol generator and the second aerosol generator 304 face each other and are exposed to the internal space. When assembled, the first aerosol generator and the second aerosol generator 304 sandwich the body 324 between them. At least in Figure 6 In some embodiments, the first aerosol generator, the second aerosol generator 304, and the body have equal planar areas. In some embodiments, one or more of the first aerosol generator, the second aerosol generator 304, and the body 324 have a greater length and / or width. In some embodiments, one of the first aerosol generator and the second aerosol generator 304 is replaced by a blank panel. The body 324 includes a body layer. The body may include multiple body layers. These body layers may be formed in a stacked manner and arranged to define some features of the article 300, such as the air inlet 314 and the aerosol outlet 318.

[0146] The wrapping layer surrounds the article 300 and forms part of the article 300. The wrapping layer may include a sheet. The wrapping layer acts as a retaining sleeve. The aerosol generator, or each aerosol generator 304, extends from the wrapping layer at its distal end. The exposed electrical contact area 323 of the heater contact portion 322 is exposed at its distal end, for example, referenced to... Figure 2 Other configurations are also conceivable, for example, at least one exposed electrical contact area 323 may additionally or alternatively be defined along a smaller longitudinal surface or edge of the article 300, and defined on a larger surface of the article defined by the aerosol generator 304.

[0147] Aerosol generator 304 Figure 7 The cross-section is shown schematically. Aerosol generator 304 is one implementation of the aerosol generator 304 of the aerosol supply system 100 described above.

[0148] Aerosol generator 304 includes an aerosol generating layer 330. The aerosol generating layer is also referred to as an aerosolizable layer. The aerosol generating layer 330 includes an aerosol generating material 302. Aerosol generator 304 includes a resistance heating layer 340. In some embodiments, the resistance heating layer 340 is formed as a conductive layer. The aerosol generating layer 330 is located on the resistance heating layer 340. The aerosol generating layer 330 is in direct contact with the resistance heating layer 340. In some embodiments, the aerosol generating layer 330 is in indirect contact with the resistance heating layer 340. In some embodiments, the resistance heating layer 340 may include a coating. As described in detail below, the resistance heating layer 340 includes a plurality of resistance heating elements 342, such as... Figure 8 and Figure 9 As shown. The resistance heating element or each resistance heating element 342 forms at least a portion of a conductive path between a pair of electrical contacts 322. The resistance heating element or each resistance heating element 342 provides a conductive path for resistively heating at least a portion of the aerosol generating material 302 to generate an aerosol. In some embodiments, the aerosol generating material 302 is in the form of a film or gel.

[0149] The resistance heating layer 340 is formed as a conductive layer. In some embodiments, the layer takes the form of at least one of a metallic layer (such as an aluminum layer) or a non-metallic material (such as graphene). The resistance heating layer 340 is in the form of a foil, such as an aluminum foil.

[0150] Aerosol generator 304 includes a support member 350. In some embodiments, the support member 350 comprises paper or cardboard material. The support member 350 provides structural support for the aerosol generator 304. A resistance heating layer 340 is located on the support member 350. The support member 350 is configured as a support layer. Figure 7 As shown, in the aerosol generator 304, the resistance heating layer 340 is sandwiched between the support member 350 and the aerosol generating layer 330.

[0151] The support 350 is electrically insulating. The resistance heating layer 340 and the support layer 350 define the substrate 352. The substrate 352 supports the aerosol generation layer 330.

[0152] Article 300 may include a laminated structure 354, which includes a resistance heating layer 340 and a support layer 350. In some embodiments, the laminated structure 354 includes an aerosol generating layer 330. The aerosol generating layer 330 may be formed in a continuous configuration or may be composed of discrete portions. The discrete portions may include one or more of the following shapes: dot-shaped, strip-shaped, spiral-shaped, or otherwise.

[0153] In some embodiments, the aerosol generating layer 330 includes an aerosol generating membrane. In some embodiments, the aerosol generating layer 330 includes multiple aerosol generating membranes. In some embodiments, the aerosol generating membrane includes multiple aerosol generating membrane regions. The multiple aerosol generating membranes and / or the multiple aerosol generating membrane regions may have different characteristics, such as different compositions, thicknesses, densities, at least one of active substances and / or flavorings, one or more aerosol forming agent materials, and optionally one or more other functional materials.

[0154] One or more of the aerosol generating layer 330, the resistance heating layer 340, and the support layer 350 may include additional layers. For example, the support layer 350 may include a backing layer or an intermediate layer. In some embodiments, the support layer 350 is omitted.

[0155] Figure 8 A resistance heating element 342 is shown. The resistance heating layer 340 includes a plurality of resistance heating elements 342. In some embodiments, the resistance heating layer 340 includes a single resistance heating element 342.

[0156] Multiple heating elements 342 can be formed as an array 344, such as Figure 9 As shown. Other configurations can also be envisioned.

[0157] The resistance heating element 342 includes a resistance heating path. The resistance heating path is formed by a conductive path. The resistance heating path is not straight; it is tortuous. The configuration of the resistance heating path can vary. The resistance of the heating element 342 can depend on the properties of the resistance heating path in the conductive layer, such as the path's length, width, thickness, and construction.

[0158] A resistance heating element 342 extends between a first-type electrical contact 360 and a second-type electrical contact 365. The first-type electrical contact 360 is configured to provide a positive electrode contact, and the second-type electrical contact 365 is configured to provide a negative electrode contact. Current flows through this path between the first-type electrical contact 360 and the second-type electrical contact 365. The contact configuration can be reversed. The first-type electrical contact 360 and the second-type electrical contact 365 constitute the heater electrical contact 322. The first-type electrical contact 360 and the second-type electrical contact 365 form at least a portion of the article electrical contact configuration 320.

[0159] The tortuous or meandering nature of the path of the resistance heating element 342 results in a greater resistance compared to the case where there is a straight path between the first type of electrical contact and the second type of electrical contact.

[0160] The resistance heating layer 340 may include a first type of electrical trace 361 extending from the resistance heating element 342. The first type of electrical trace 361 includes a first type of electrical contact 360. The first type of electrical contact 360 is configured to electrically connect to the device electrical connector 230. The first type of electrical contact 360 includes a first type of exposed contact area 362. The first type of exposed contact area 362 is exposed on the article for direct connection to the device electrical connector 230.

[0161] The resistance heating layer 340 may include a second type of electrical trace 366 extending from the resistance heating element 342. The second type of electrical trace 366 includes a second type of electrical contact 365. The second type of electrical contact 365 is configured to electrically connect with the device electrical connector 230. The second type of electrical contact 365 includes a second type of exposed contact area 367. The second type of exposed contact area 367 is exposed on the article 300 for direct connection with the device electrical connector 230.

[0162] As discussed in detail below, in some embodiments, the conductive path of the resistance heating element 342 is formed by defining at least one electrical barrier 346 in the resistance heating layer 340. In some embodiments, the electrical barrier 346 is formed by cutting electrical barrier limiting portions (i.e., electrically insulating portions) such as gaps, channels, or slots in a sheet formed of conductive material, thereby forming the resistance heating layer 340. In some embodiments, the conductive element 342 is pre-formed to define the resistance heating element or each resistance heating element 342, and then the resistance heating layer is applied to the support 350. In some embodiments, the resistance heating layer 340 is first applied to the support 350, and then the resistance heating element or each resistance heating element 342 is defined in the resistance heating layer 340. The resistance heating element or each resistance heating element 342 defining the resistance heating layer 340 may be a printed heater.

[0163] At least one electrical barrier 346 defines a first type of electrical trace 361 and a second type of electrical trace 366.

[0164] In some embodiments, the traces of the resistance heating element or each resistance heating element 342 have a width ranging from 0.5 mm to 1 mm (two exemplary examples have widths of 0.93 mm and 0.72 mm, respectively), and the spacing between the traces is less than about 0.25 mm (two exemplary examples have spacings of 0.2 mm and 0.05 mm, respectively). The resistance heating element or each resistance heating element 342 may have an overall size of about 10 mm x 10 mm. In other exemplary embodiments, other sizes are also possible. By forming the resistance heating element or each resistance heating element 342 with these dimensions using an aluminum foil with a thickness of 0.006 mm and a resistivity between 2 µOhmcm and 6 µOhmcm, the resistance of the path is calculated to be about 1 Ohm. In one exemplary embodiment, the measured resistance is between 0.83 Ohm and 1.31 Ohm.

[0165] like Figure 9 As shown, the resistance heating layer 340 can be formed as a plurality of resistance heating elements, generally indicated by reference numerals 342a, 342b, 342c, 342d, and 342e. Each of the resistance heating elements 342a-342e extends from a corresponding first-type electrical contact (generally indicated by reference numerals 360a, 360b, 360c, 360d, and 360e) to a single second-type electrical contact 365. The number of electrical contacts can vary. Thus, each resistance heating element 342a-342e extends between discrete first-type electrical contacts and shared second-type electrical contacts.

[0166] Each of the resistance heating elements 342a-342e provides a conductive path for resistively heating a portion of the aerosol generating material 302 to generate an aerosol at a corresponding portion of the aerosol generator 304.

[0167] Individual first-type electrical contacts 360a-360e allow current to be individually supplied to each of the plurality of resistance heating elements 342a-342e. This allows for control of heating different regions of the aerosol generation layer 330. For example, the aerosol generator may be provided with five aerosol generation zones. The resistance heating layer 340 allows each of these zones to be activated individually. Thus, for example, a single consumable incorporating a single aerosol generator 304 can produce five aerosol extractions, and a single consumable incorporating two aerosol generators 304 can produce ten aerosol extractions.

[0168] In the exemplary resistance heating layer 340, a plurality of first-type electrical contacts 360a-360e, such as positive electrical connections, are provided, and a single second-type electrical contact 365, such as a negative electrical connection, is provided. This is not necessary in all implementations. For example, multiple second-type contacts may be provided. In some embodiments, each resistance heating element 342a-342e includes a corresponding first-type electrical contact 360 and a corresponding second-type electrical contact 365.

[0169] exist Figure 9 In the embodiment of the resistance heating layer 340 shown, first-type electrical contacts 360a-360e are arranged on the first edge 363 of the resistance heating layer 340, and second-type electrical contacts 365 are arranged on the second edge 368 of the resistance heating layer 340. This allows for convenient electrical connection, but of course, many other configurations are also possible, some of which will be discussed further below.

[0170] Figure 10 This is a flowchart illustrating a portion of a method or algorithm for forming an aerosol generator 304 according to an exemplary embodiment (generally indicated by reference numeral 400).

[0171] Method or algorithm 400 begins with operation 402, in which a resistance heating layer is formed as one or more heating elements (e.g., multiple heating elements), wherein each resistance heating element extends from a first type of electrical contact to a second type of electrical contact. In use, the heating element or each heating element can be used to provide a conductive path for resistively heating a portion of the aerosol-generating material to generate an aerosol. In the presence of a support, the formation of the resistance heating element or each resistance heating element can be performed before or after the resistance heating layer is applied to the support. The resistance heating layer can be attached to the support, or mounted or formed on the support in different configurations.

[0172] At operation 404, the formed resistance heating layer is arranged to contact the aerosol generation layer, wherein the aerosol generation layer comprises an aerosol generating material. Algorithm 400 can be used to fabricate the aforementioned aerosol generator 304.

[0173] Figure 11 An aerosol generator 304 under construction according to one embodiment is shown. An aerosol generating material 302 is formed on a resistance heating layer 340 by means of, for example, spraying, coating, dispensing, or some other method of deposition. In an exemplary implementation of operation 404, an aerosol generating layer 330 is disposed on the resistance heating layer 340, as indicated by arrow 406.

[0174] Figure 12 A resistance heating layer 340 is shown being formed according to an exemplary embodiment. The resistance heating layer 340 is being cut using a laser cutter 408. Cutting the resistance heating layer 340 can be used to form the path of the heating element described herein. The use of a laser cutter 408 (or some other cutting process) is not the only method that can be used to generate the resistance heating layer 340 described herein. Some exemplary methods will be described below.

[0175] Figure 13 This is a flowchart illustrating a portion of a method or algorithm for forming an aerosol generator 304 (generally indicated by reference numeral 410). The method or algorithm 410 begins at operation 412, in which a resistance heating layer is provided. At operation 414, one or more resistance heating elements are formed in the resistance heating layer by chemical etching. Operations 412 and 414 are an exemplary implementation of operation 402 of the method 400 described above. An aerosol-generating material is then disposed on the resistance heating layer, thereby achieving operation 404 described above.

[0176] Figure 14This is a flowchart illustrating a portion of a method or algorithm for forming an aerosol generator 304 (generally indicated by reference numeral 418). The method or algorithm 418 begins with operation 420, in which one or more heating elements are formed, at least partially, by printing a resistance heating layer. Thus, operation 420 is an exemplary implementation of operation 402 of the algorithm 400 described above. Aerosol-generating material is then disposed on the resistance heating layer, thereby achieving operation 404.

[0177] The cutting, etching, and printing methods described above are provided by way of example; other additional or alternative methods are also possible. For example, a so-called "hot foiling" method can be used, in which the heating element is made of a resistance heating layer and is then assembled / bonded to a support. Other techniques, such as die-cutting, can also be used. Furthermore, two or more techniques can be combined (e.g., by adding more conductive material, such as additional foil, printing material, etc., the conductivity of the connection traces can be increased). Those skilled in the art will recognize many other techniques or combinations of techniques that can be used in the implementation of the principles described herein.

[0178] Figure 15 This is a flowchart illustrating an operational method or algorithm (generally indicated by reference numeral 424) according to an exemplary embodiment. Method or algorithm 424 can be implemented, for example, using any aerosol generator described herein. Method or algorithm 424 is initiated when a command to initiate heating is received in one example of operation 426. In response to the command to initiate heating, (in operation 428) it is determined whether a heating element is available. As discussed above, multiple heating elements may be provided. Operation 428 may include determining which heating elements have been used and / or which corresponding available aerosol generating materials have been exhausted.

[0179] If a heating element is available, the algorithm moves to operation 430, where the available heating element is used. As discussed above, the heating element can be individually controllable, for example, power can be supplied to a single heating element. After operation 430 is completed, the algorithm terminates at operation 432. If it is determined at operation 428 that no heating element is available, for example because all heating elements have been exhausted, then the algorithm terminates at operation 432. This may mean that the consumable part used to implement algorithm 424 needs to be replaced.

[0180] Figure 16 A resistive heating layer 340 in formation according to one embodiment is shown. The resistive heating layer 340 is being cut using a laser cutter 408, but other methods, such as chemical etching or printing, as discussed above, may also be used. The cutting of the conductive layer 340 forms the heating element described herein.

[0181] exist Figure 16 In this embodiment, the cut path is a linear path extending along the length of the conductive layer 120.

[0182] Figure 17 Another embodiment of the resistance heating layer 340 is shown. The resistance heating layer 340 can be formed using the laser cutter 408 described above or similar devices or other methods. The resistance heating layer 340 includes a plurality of resistance heating elements 342, each of which is a linear heating element, comprising a conductive path extending along the length of the resistance heating layer 340. Each resistance heating element 342 extends from a first type of electrical contact 360 (e.g., a positive electrical connection) to a second type of electrical contact 365 (e.g., a negative electrical contact). In this embodiment, both types of electrical contacts are located at the same end of the resistance heating layer 340 and are arranged adjacent to each other. In this configuration, as in some other embodiments, there is no shared second type of electrical contact; instead, each heating element has a separate first type of electrical contact and a separate second type of electrical contact.

[0183] Figure 18 Another embodiment of the resistance heating layer 340 is shown. The resistance heating layer 340 can be formed using the laser cutter 408 described above or similar devices or other methods. The resistance heating layer 340 includes a plurality of heating elements 342, each of which is a linear heating element and includes a conductive path extending along the length of the resistance heating layer 340. Each resistance heating element 342 extends from a first type of electrical contact 360 (e.g., a positive electrical connection) to a second type of electrical contact 365 (e.g., a negative electrical contact). In such an embodiment, different types of electrical connections are provided at opposite ends of the resistance heating layer 340, and a common second type of electrical contact is provided. Although a linear path is provided here, resistance can be increased by providing a creneled path that acts as a tortuous path. Note that the path in any other embodiment described herein can also be creneled.

[0184] Figure 19 The distal end of article 300 is shown. As illustrated, body 324 includes a plurality of body layers 325. The body layers 325 are arranged in a stacked manner. The body layers 325 form a laminated structure. In some embodiments, the body layers 325 are cardboard layers. Other suitable materials may also be used. The body layers 325 are configured to define certain features of article 300. In some embodiments, at least one body layer includes a gap defining an air inlet 315. This gap defines an opening 314.

[0185] The aerosol generator 304 includes a resistance heating layer 340. The resistance heating layer 340 includes resistance heating elements 342, a first type of electrical contact 360, and a single second type of electrical contact 365. The first type of electrical contact provides a positive electrical connection for each of the plurality of heating elements 342, for example, and the single second type of electrical contact provides a common negative electrical connection for the plurality of heating elements 342. The first type of electrical contact 360 and the second type of electrical contact 365 (i.e., heater contact 322) together form at least a portion of the article electrical contact configuration 320 of the aerosol generator 304.

[0186] The resistance heating element 342 is located on the inner side of the resistance heating layer 340. The inner side defines the first side 306 of the aerosol generator 304, as shown below. Figure 3 As shown. The heater contacts 322 are located on the second side 307 of the resistance heating layer 340. The second side 307 defines the outer side of the aerosol generator 304. The heater contacts 322 are exposed so that they can contact the device electrical connector 230. The heater contacts 322 are located on the side of the resistance heating layer 340 opposite to the resistance heating element 342. Other configurations are also conceivable.

[0187] The support layer 350 is located between the inner portion of the resistance heating layer 340 and the outer portion of the resistance heating layer 340.

[0188] A folded portion 370 is formed in the resistance heating layer 340. The folded portion 370 defines the heater contact portion 322. Figures 2 to 4 and Figure 19 As shown, the folded portion 370 extends perpendicular to the longitudinal axis of the aerosol generator 304. The folded portion 370 defines a vane 372. A heater contact portion 322 is located on the vane 372. The vane defines a contact panel. The remainder of the blank defines a main panel.

[0189] In embodiments with support layer 350, support layer 350 is folded in some embodiments. Substrate 352 is folded at fold 370. In some embodiments, support layer 350 terminates at fold 370. In some embodiments, fold 370 extends parallel to the longitudinal axis of aerosol generator 304.

[0190] The folded portion of the resistance heating layer 340 is attached in the folded position. In some embodiments, this folded portion is attached by, for example, adhesive. Other fixing methods are also conceivable.

[0191] Fold portion 370 defines a first type of exposed contact area 362. Fold portion 370 defines a second type of exposed contact area 367. Electrical traces 361 and 366 are electrically connected across fold portion 370. The heater contact portion 322 of the first type of electrical trace 361 and the heater contact portion of the second type of electrical trace 366 are defined on a second side of the resistance heating layer 340. A portion of the first type of electrical trace 361 and a portion of the second type of electrical trace 366 extend on a first side of the resistance heating layer 340. In some embodiments, the resistance heating element extends from fold portion 370. Other configurations are also contemplated.

[0192] Device 200 includes a plurality of connector electrical contacts 232 of electrical connector 230. The configuration of device connector 230 depends on the configuration of heater contacts 322 of aerosol generator 304. In some embodiments, such as Figure 19 The aerosol generator 300 shown includes a plurality of heater contacts 322, which include a plurality of first-type heater contacts 360 and a second-type heater contact 365. The article 300 includes another set of heater contacts 322 located on the other side of the article 300, corresponding to a second aerosol generator 304.

[0193] Figure 20 A device connector 230 of an aerosol supply device 200 used in some embodiments is shown. The connector 230 has a separate connector electrical contact 232 for connection with a heater contact 322.

[0194] Figure 21 An aerosol supply system 100 is schematically shown. System 100 includes an article 300 and an aerosol supply device 200, both shown in block diagrams. Device 200 includes a first connector 230a and a second connector 230b.

[0195] When the article 300 is inserted into the aerosol supply device 200, connectors 230a and 230b enable the aerosol supply device 200 to provide regulated or controlled voltage and / or current to the respective first-type heater contacts 360 and second-type heater contacts 365 of the aerosol generator 304. The aerosol supply device 200 may include connector configurations configured to supply power to connectors 230a and 230b. The aerosol supply device 200 may, for example, operate as described above.

[0196] Figure 22 This is a flowchart illustrating a method or algorithm for forming an aerosol generator 304 according to an exemplary embodiment (generally indicated by reference numeral 440).

[0197] Method or algorithm 440 begins with operation 442, in which a resistive heating layer is formed as at least one resistive heating element, which, or each heating element, provides a conductive path for resistively heating at least a portion of the aerosolizable material to generate an aerosol. Exemplary heating elements that may be formed in operation 442 are described elsewhere in this document.

[0198] At operation 442, an aerosol generating material is applied and / or formed on the resistance heating layer.

[0199] Operations 442 and 444 of method or algorithm 440 are similar to (and may be the same as) operations 402 and 404 of method or algorithm 400 described above.

[0200] In operation 446, at least one first-type electrical contact is provided on the resistance heating layer. The forming method can be any of the methods described above. In operation 448, at least one second-type electrical contact is provided on the resistance heating layer. The forming method can be any of the methods described above.

[0201] In some embodiments, the first type of electrical contact and the second type of electrical contact are formed along or near a single edge of the resistance heating layer. In some embodiments, the first type of electrical contact and the second type of electrical contact are formed along or near different edges of the resistance heating layer.

[0202] In some embodiments, a first type of electrical contact (e.g., one or more positive electrode connections) is disposed along a first edge of the resistance heating layer. In some embodiments, a second type of electrical contact (e.g., one or more negative electrode connections) is disposed along a second edge of the resistance heating layer. Operations 446 and 448 may be performed in different orders or simultaneously. Furthermore, operations 446 and 448 may be performed together with operation 442.

[0203] At operation 450, the resistance heating layer is folded. In some embodiments, the support layer is folded together with the resistance heating layer. In some embodiments, the resistance heating layer is folded such that the first type of electrical contact and the second type of electrical contact are disposed adjacent to each other, as discussed in detail below.

[0204] Figures 23 to 25 An embodiment of an aerosol generator 304 being formed according to algorithm 440 is shown.

[0205] Figure 23Another embodiment of an aerosol generator 304 in formation is shown. The resistance heating layer 340 is being cut using a laser cutter 408. A pre-folded configuration defines a blank for forming the aerosol generator 304. In some embodiments, the blank defines a fold line along which it is folded during the formation of the aerosol generator. The aerosol generator 304 blank includes the resistance heating layer 340 and a support layer 350. The resistance heating layer 340 and the support layer 350 define a panel defined by the fold line.

[0206] like Figure 23 As shown, the resistance heating layer 340 is formed as a plurality of heating elements 192, but the number may vary and may be a single element. A plurality of first-type electrical contacts 360 (e.g., positive electrical contacts) are provided along a first edge of the conductive layer (shown as one contact for each heating element). A single second-type electrical contact 365 is provided along a second edge of the resistance heating layer 340. In some embodiments, the contacts are spaced apart from the edges. As discussed above, each of the plurality of heating elements extends from the first-type electrical contact to the second-type electrical contact.

[0207] The path for forming the heating element or each heating element 342 is created by cutting the resistance heating layer 340 using a laser cutter 408. As discussed above, laser forming or some other cutting process is not the only way to produce the resistance heating layer 340 described above. Some exemplary alternatives include chemical etching and printing.

[0208] like Figure 24 As shown, an aerosol generation layer 200 is provided on the resistance heating layer 340. Then press... Figure 24 The arrows in the diagram indicate the folded blank. In this embodiment, the folded portion is formed parallel to the longitudinal direction of the aerosol generator 304. Two folded portions are formed. A first panel 375 is defined to include a heating element 342. A second panel 376 is formed to include a plurality of first-type electrical contacts 360. A third panel 377 is formed to include second-type electrical contacts 365. An aerosol generating layer 330 is located on the first panel 375. Figure 25 The folded aerosol generator 304 is shown.

[0209] In some embodiments, the properties of each heating element 342 may change, for example, due to corrosion buildup on the article contact 322 or the device (i.e., connector) electrical contact 232. Taking this into account when operating the device 200 is beneficial to ensure that the article 300 is properly heated. Various embodiments designed to address this issue will be discussed below.

[0210] Figure 26An aerosol supply system 100 including an aerosol supply device 200 and an article 300 is schematically shown.

[0211] Article 300 includes a first article electrical contact 360 and a second article electrical contact 365. The first article electrical contact 360 and the second article electrical contact 365 are article electrical contacts 322. Article 300 also includes a resistive element 342. Figure 26 In this embodiment, the resistive element may be a resistance heating element 342. The first electrical contact 360 and the second electrical contact 365 enable electrical connection between the resistance heating element 342 and the article 300. The resistance heating element 342 may be arranged to heat the aerosol-generating material 302 present in the article 300.

[0212] The aerosol supply device 200 includes a product receiving portion 206, which can be shaped to receive a product 300 in use. The product receiving portion 206 can be shaped as a receiving section (e.g., a cavity) for receiving the product 300. The aerosol supply device 200 includes an electrical connector 230, which includes a device electrical contact 232 (also referred to as a connector electrical contact 232), which can be configured to engage with a product electrical contact 322. The device electrical contact 232 can provide power to the product electrical contact 322, such that power can be provided to a resistance heating element 342 to heat the aerosol generating material 302.

[0213] The aerosol supply device 200 also includes a control system 222, which may include a processor 223 and a memory 225. The control system 222 may be configured to determine the electrical characteristics (e.g., resistance) between the first article electrical contact 360 and the second article electrical contact 365 during use, and to control the operation of the aerosol supply device 200 based on the determined resistance. The determination of the electrical characteristics (e.g., resistance) can be achieved in any suitable manner. For example, it can be achieved by applying a fixed voltage between the first article electrical contact 360 and the second article electrical contact 365 and measuring the current between them. The resistance can then be determined using Ohm's law. Alternatively, a fixed current can be provided, and the voltage drop between the first article electrical contact 360 and the second article electrical contact 365 can be measured. Again, the resistance can be determined using Ohm's law. Figure 26 As shown, the aerosol supply device 200 may also include a temperature sensor 240. In some embodiments, such as Figure 26 As shown, the aerosol supply device 200 may also include an indicator element 229, which may be in the form of an LED, a speaker, a display, or a tactile device. The operation of the device 200 and the article 300 can then be appropriately controlled using electrical characteristics (e.g., resistance). This will be described in more detail below.

[0214] Figure 27 It is a flowchart illustrating the operations. Figure 26 Method 450 of the aerosol supply device 200 shown. It should be understood that method 450 is a method of operating the device during use. Therefore, it should be understood that method 450 presupposes that the article 300 has been inserted into the device 200. In step 452, the control system 222 determines the resistance between the first article electrical contact 360 and the second article electrical contact 365. (As per...) Figure 26 As explained, the control system 222 can be configured to measure the current between the first article electrical contact 360 and the second article electrical contact 365, and determine the resistance based on the measured current.

[0215] In step 454, the determined resistance can then be compared with a second resistance range (i.e., a second operating range). The second resistance range may be an optimal resistance range. In some embodiments, the second resistance range may be predetermined, for example, between fixed values, and defined between a third threshold and a fourth threshold. The predetermined second resistance range may include the resistance range in which the aerosol supply device 200 can operate with preferred performance characteristics (e.g., improved efficiency).

[0216] If the determined resistance is within the second resistance range, the control system 222 can operate the device 200 normally (e.g., provide power to the product electrical contact 322, thereby energizing the heating element 342), as shown in step 457 of method 450.

[0217] The resistance between the first article electrical contact 360 and the second article electrical contact 365 may vary due to corrosion occurring on the contacts (e.g., corrosion deposits), due to the temperature coefficient of resistance of the material, or due to a failure of the resistance heating element 342. Since the article receiving portion 206 is an area where aerosols are generated, it may be a humid environment, and therefore contact corrosion may be a problem. Since an increase in resistance between the contacts may indicate a failure of the article 300, it may be advantageous to prevent further operation of the device 200 when the resistance is too high or too low, or to indicate to the user that the device 200 and / or the article 300 require maintenance when the resistance is too high or too low, or when the resistance is not yet too high or too low but is close to a value that may be too high or too low. The resistance between the first article electrical contact 360 and the second article electrical contact 365 may also depend on the quality of the connection between the first article electrical contact 360 and the second article electrical contact 365 and the device electrical contact 232.

[0218] Based on the above, if the determined resistance is outside the second resistance range, the determined resistance can be compared with the first resistance range (i.e., the first operating range), as shown in step 455 of method 450. The first resistance range can be an acceptable resistance range. The first resistance range can be defined between a first threshold and a second threshold. In some embodiments, the first resistance range can be predetermined, for example, between fixed values ​​(fixed thresholds). The predetermined first resistance range can include an acceptable resistance range in which operating the aerosol supply device 200 is an acceptable resistance range.

[0219] If the determined resistance is within a first resistance range but outside a second range, the control system can operate device 200, but only needs to provide instructions that device 200 and / or product 300 require maintenance, such as... Figure 27 The step 458 is shown. This indication can be provided via an indicating element 229, which can be, for example, a lamp, display, speaker, etc. The indication can be a visual indication, an auditory indication, or a tactile indication. In some embodiments, in response to determining that the measured resistance is outside the second resistance range (even if it is within the first resistance range), the control system 222 can prevent further operation of the device 200 (e.g., by not supplying power to the article electrical contact 322, thereby preventing power from being supplied to the heating element 342).

[0220] In some implementations, such as Figure 27 As described, if the determined resistance is outside the first resistance range, the control system 222 can prevent the device 200 from operating further (e.g., it can prevent the supply of power to the article electrical contact 322, and thus prevent the supply of power to the heating element 342), such as Figure 27 As shown in step 459. In some embodiments, in addition to not operating device 200, control system 222 can provide instructions that device 200 and / or article 300 require maintenance.

[0221] Method 450 may be executed when device 200 is started (e.g., at the start of a usage session) and then not executed again for the remainder of the usage session. Alternatively, method 450 may be executed continuously for the entire usage session. In some embodiments, method 450 may be executed at the start of each usage session. In some embodiments, method 450 may be executed multiple times within a usage session.

[0222] Therefore, it can be seen that if the resistance at the product electrical contact 322 is too high (e.g., due to corrosion on the product electrical contact 322 or device electrical contact 232), the device can be prevented from operating for safety reasons, and / or the user can be advised that maintenance is required (e.g., cleaning the product electrical contact 322 or device electrical contact 232).

[0223] In the above embodiments, the threshold (e.g., at least one of a first threshold, a second threshold, a third threshold, or a fourth threshold) is predetermined. However, this is not necessary. In some embodiments, one or more thresholds can be set during use of the device 200. Therefore, the one or more thresholds can be considered dynamic thresholds. The one or more thresholds can be changed (e.g., by the control system 222, for example, by the processor 223 of the control system 222) and depend on one or more external factors. In an exemplary embodiment, the threshold resistance value (e.g., a first operating range and / or a second operating range) can dynamically depend on the current temperature of the device (e.g., the current temperature measured by the temperature sensor 240). For example, when the temperature of the device 200 is low, the threshold resistance at the upper limit of the first operating range can be increased (because a greater degree of resistance heating is allowed at this time), and when the temperature of the device 200 is high, the threshold at the upper limit of the first operating range can be decreased (because a smaller degree of resistance heating is allowed at this time). The method 450 described above can utilize predetermined thresholds and / or thresholds set during use of the device 200.

[0224] The temperature dependence of the threshold may be advantageous because the danger of continuing to operate device 200 when the resistance is too high lies in generating a dangerous level of resistance heating. However, when the temperature of device 200 is low, a greater degree of heating can be allowed before reaching the dangerous temperature of device 200. Therefore, when the temperature of device 200 is low, device 200 can be allowed to continue operating for a longer period of time, thereby increasing user convenience. Conversely, when the temperature of device 200 is high, a smaller degree of heating can be allowed before reaching the dangerous temperature of device 200. Therefore, when the temperature of device 200 is high, device 200 cannot be allowed to continue operating for too long, thereby improving safety.

[0225] The above is about Figure 27 The described implementation is discussed in the context of electrical characteristics in the form of resistance, wherein the second operating range and the first operating range are defined by resistance values. However, it should be understood that the same method can be applied to electrical characteristics in the form of current or voltage, wherein the first operating range and the second operating range are defined by current values ​​or resistance values, respectively.

[0226] Figure 28 This is a flowchart illustrating the operation according to another embodiment of the present invention. Figure 26Another method 460 of the aerosol supply device 200 shown. Method 460 is a method of operating the device 200 during use; therefore, it should be understood that this method presupposes that the article 300 has been inserted into the device 200. In method step 463, the control system 222 can determine the current between the first article electrical contact 360 and the second article electrical contact 365. This current can be considered as the electrical characteristics between the first article electrical contact 360 and the second article electrical contact 365. This determination can be achieved by any suitable means, for example, by applying a fixed voltage between the first article electrical contact 360 and the second article electrical contact 365 and measuring the current between them.

[0227] In step 464, the determined current is compared with a target current. This target current can be considered a threshold. The target current can be a fixed value, considered as the preferred current for operating the aerosol supply device 200. In some embodiments, the target current can be a dynamic value that can be changed (e.g., by the control system 222, for example, by the processor 223 of the control system 222) and depends on one or more external factors. In one example, the target current can dynamically depend on the current temperature of the device 200 (e.g., the current temperature measured by the temperature sensor 240). For example, when the temperature of the device 200 is low, the target current can be increased (because a greater degree of resistance heating is allowed at this time), and when the temperature of the device 200 is high, the target current can be decreased (because a smaller degree of resistance heating is allowed at this time).

[0228] In some implementations, the target current may include a target current range (e.g., between an upper threshold and a lower threshold).

[0229] If the determined current is less than the target value, the control system 222 can operate the device 200 to increase the voltage across the electrical contact 322 of the product proportionally to the determined current to achieve the target current, as shown in step 467 of method 460. If the determined current is equal to the target value, the control system 222 can operate the device 200 to maintain the voltage across the electrical contact 322 of the product at the current level, as shown in step 468 of method 460. If the determined current is greater than the target value, the control system 222 can operate the device 200 to decrease the voltage across the electrical contact 322 of the product proportionally to the determined current to achieve the target current, as shown in step 469 of method 460. It should be understood that although current is determined in this embodiment, since current, voltage, and resistance are directly related according to Ohm's law, determining the current between the electrical contacts 360 and 365 of the product based on a fixed voltage and adjusting the power supply accordingly actually takes into account the resistance between the electrical contacts 360 and 365 of the product.

[0230] It should be understood that method 460 may be executed when device 200 is started (for a particular usage session) and then not executed again for the rest of the usage session. Alternatively, method 460 may be executed continuously for the rest of the usage session. The advantage of this implementation is that the target current is maintained even if the temperature coefficient of resistance of the material of resistive element 342 causes a change in resistance (e.g., a change in resistance occurs when resistive element 342 heats up).

[0231] It should also be understood that method 40 can be iterative. For example, in step 464, if it is determined that the current is less than the target value, the voltage can be increased in a preset increment. The method can then return to step 462, and in step 464, the newly determined current (and the updated voltage) can be compared with the target current to determine whether any further changes to the applied voltage are needed.

[0232] Therefore, it can be seen that if the defined current (and thus the resistance) between the product electrical contacts 322 varies due to slight corrosion on the product electrical contacts 322 or the device electrical contacts 232 (i.e., not severe enough to prevent the use of the device) or slight misalignment when these contacts are joined, or due to variations caused by different products 300 with different resistive elements 342 being used with the device 200, the operation of the device can be adjusted to accommodate these resistance variations.

[0233] In some embodiments, the article may include a plurality of resistive elements, and the method described herein may be performed on each of the plurality of resistive elements (e.g., simultaneously).

[0234] The applicant also recognizes that the determined resistance (or even related electrical characteristics) can be used to identify the type of article 300 that has been inserted into device 200. Accurate identification of the type of article 300 inserted into device 200 can allow for the application of customized control schemes, making it possible to adjust the operation of device 200 to work with a specific article 300.

[0235] Although the above embodiments are described in the context of applying a fixed voltage and measuring the current, it should be understood that the method can alternatively apply a fixed current and measure the voltage drop between the two contact portions 360, 365 of the article.

[0236] The above method can be repeatedly applied to multiple sets of product electrical contacts within the device, for example, where each set of product electrical contacts is connected to a different heating element within the device. In such embodiments, the method can ensure the proper operation of multiple heating elements.

[0237] Figure 29Another aerosol supply device 200 and two different articles suitable for use with the device 200 are schematically shown, namely a first article 300a and a second article 300b. Both the first article 300a and the second article 300b include a first article electrical contact 360 and a second article electrical contact 365. The first article electrical contact 360 and the second article electrical contact 365 are article electrical contacts 322. Articles 300a and 300b also each include corresponding resistive elements 342a and 342b, in... Figure 26 In this embodiment, these resistive elements may be resistive heating elements 342a and 342b. The first electrical contact 360 and the second electrical contact 365 enable electrical connection between the resistive heating elements 342a and 342b. The resistive heating elements 342a and 342b may be arranged to heat the aerosol-generating material 302 present on the articles 300a and 300b.

[0238] Resistor elements 342a and 342b can be formed into electrical traces, as mentioned above. Figure 8 and Figure 9 The subject of discussion. From Figure 29 It can be seen that the trace length of the resistive element 342b of the second product 300b is much longer than the trace length of the resistive element 342a of the first product 300a. Therefore, the resistance of the resistive element 342b of the second product 300b (and thus the resistance at the electrical contact 322 of the product) can be greater than the resistance of the resistive element 342a of the first product 300a.

[0239] Similar to the embodiments described above, the aerosol supply device 200 in this embodiment includes a product receiving portion 206, which can be configured to receive products 300 during use, such as a first product 300a or a second product 300b. The aerosol supply device 200 includes an electrical connector 230, which includes an electrical contact portion 232 configured to engage with a product electrical contact portion 322. The device electrical contact portion 232 can provide power to the product electrical contact portion 322, thereby providing power to the resistance heating elements 342a, 342b to heat the aerosol generating materials 302a, 302b.

[0240] The aerosol supply device 200 also includes a control system 222, which includes a processor 223 and a memory 225. The control system 222 can be configured to determine the resistance between the first article electrical contact 360 and the second article electrical contact 365 during use, and to control the operation of the aerosol supply device 200 based on the determined resistance. The control system 222 can be configured to measure the resistance between the first article contact 360 and the second article contact 365. This can be achieved in any suitable manner. For example, this can be achieved by applying a fixed voltage between the first article contact and the second article contact 360, measuring the current between them, and determining the resistance using Ohm's law. Alternatively, this can be achieved by applying a fixed current between the first article contact 360 and the second article contact 365, measuring the voltage drop between the first and second article contacts 365, and determining the resistance using Ohm's law.

[0241] In the embodiments of the type discussed above, the resistance between the electrical contacts 322 of the articles is different between the first article 300a and the second article 300b. This difference in resistance can be used to identify different articles 300 and helps to adjust the control of the operation of the device 200 according to the article 300 being used.

[0242] In some embodiments, the memory 225 of the control system 222 may store multiple control schemes. Each control scheme may correspond to a different article 300 and is therefore associated with a resistance value specific to that article type. Each control scheme may include information such as operating voltage, indication information (e.g., informing the user that article type B has been inserted), etc. Thus, articles 300 that have been inserted into the article receiving section 206 of the aerosol supply device 200 can be easily identified, and the operation of the device 200 can be adjusted according to the control scheme depending on the article 300 inserted into the article receiving section 206.

[0243] Figure 30 It is a flowchart illustrating the operations. Figure 29 The method 470 of the aerosol supply device 200 shown. In step 472, the resistance between the first article electrical contact 360 and the second article electrical contact 365 is determined. In step 474, the determined resistance is compared with a resistance value stored in memory 225 to match the determined resistance with one of the stored resistance values. The control system 222 may impose a tolerance on the comparison result of step 474 (e.g., to compensate for minor resistance variations due to corrosion buildup on the article electrical contact 322 or the device electrical contact 232). The memory 225 may, for example, store a lookup table that details the different articles 300 and their associated resistances and related control schemes.

[0244] In step 476, after the determined resistance matches the stored resistance value, the control system 222 controls the operation of the device 200 according to the control scheme associated with the stored resistance value.

[0245] This operating method can advantageously facilitate the operation of the device 200 and the article 300, and does not necessarily require the user to input any information related to the type of article 300 already inserted into the device 200. This makes the operation of the device 200 and the article 300 easier for the user. Although the above method is described in the context of determining resistance, it should be understood that other electrical characteristics (which may be related to resistance) can also be determined and used to identify the type of article 300. For example, a fixed voltage can be applied to the electrical contacts 360, 365 of the article, and the current between them can be measured. This current (which is related to resistance) can then be used to identify which article 300a, 300b has been inserted. This can be achieved in a manner similar to the embodiment described above, i.e., by comparing the current with the current value stored in the controller 222. Similarly, voltage measurement can also be used, i.e., providing a fixed current and measuring the voltage drop across the electrical contacts 360, 365 of the article.

[0246] Figure 31 Another aerosol supply device 200 and an article 300 suitable for use with the device 200 are schematically shown. Article 300 includes a first article electrical contact 360 and a second article electrical contact 365. The first article electrical contact 360 and the second article electrical contact 365 are article electrical contacts 322. Article 300 also includes a resistance heating element 342. The first electrical contact 360 and the second electrical contact 365 can provide electrical communication between the resistance heating element 342. The resistance heating element 342 can be arranged to heat the aerosol generating material 302 present in article 300.

[0247] Article 300 also includes a second resistive element 343 (i.e., an additional resistive element). The second resistive element 343 may not be a resistance heating element, but may be used solely to provide a characteristic resistance (i.e., an identification resistance) so that article 300 can be identified by device 200. The second resistive element 343 can be considered an identification resistive element. The second resistive element 343 includes a first article electrical contact 364 and a second article electrical contact 369. The first article electrical contact 364 and the second article electrical contact 369 of the second resistive element 343 enable electrical connection between the second resistive element 343 and the second article electrical contact 369.

[0248] In some embodiments, the second resistive element 343 may be the only resistive element (e.g., the article may not include a resistance heating element).

[0249] The aerosol supply device 200 includes a product receiving portion 206, which can be shaped to receive a product 300 in use. The aerosol supply device 200 includes a device electrical contact portion 232, which can be configured to engage with a product electrical contact portion 322. The device electrical contact portion 232 can provide power to the product electrical contact portion 322, thereby providing power to a resistance heating element 342 to heat the aerosol generating material 302.

[0250] The aerosol supply device 200 may further include a second device electrical contact 234, which may be configured to engage with a first article electrical contact 364 and a second article electrical contact 369 of the second resistive element 343. The second device electrical contact 234 may enable electrical communication (e.g., energization) between the first article electrical contact 364 and the second article electrical contact 369 of the second resistive element 343.

[0251] The aerosol supply device 200 also includes a control system 222, which includes a processor 223 and a memory 225. The control system 222 can be configured to determine the resistance between the first article electrical contact 364 and the second article electrical contact 369 of the second resistive element 343 during use, and to control the operation of the aerosol supply device 200 based on the determined resistance. In other embodiments, other electrical characteristics can be determined (e.g., measured), such as the current between the first article electrical contact 364 and the second article electrical contact 369, or the voltage drop across the first and second article electrical contacts, and the control system 222 can control operation based on these electrical characteristics.

[0252] Figure 31 The device 200 can also be arranged according to Figure 30 The method 470 shown is used for operation. Specifically, the memory 225 of the control system 222 can store multiple control schemes. Each control scheme can correspond to a different article 300 and is therefore associated with a resistance value specific to that article type (e.g., the resistance value of the second resistive element 343). Each control scheme can include information such as operating voltage, indication information (e.g., informing the user that article type B has been inserted), etc. Therefore, the operation of the device 200 can be adjusted according to the control scheme depending on the article 300 inserted into the article receiving section 206.

[0253] In step 472, the resistance at the first article electrical contact 364 and the second article electrical contact 369 of the second resistive element 343 is determined. In step 474, the determined resistance is compared with a resistance value stored in memory 225 to match the determined resistance with one of the stored resistance values. The control system 222 may apply a tolerance to the comparison result of step 474 (e.g., to compensate for minor resistance variations due to corrosion buildup on the article electrical contacts 364, 369 or the device electrical contact 234).

[0254] In step 476, after the determined resistance matches the stored resistance value, the control system 222 can control the operation of the device 200 according to a control scheme associated with the stored resistance value. Similarly, although this method is described in the context of resistance, it can also be implemented by measuring current and / or voltage drop.

[0255] In another embodiment, article 300 may include a plurality of resistance heating elements 342, as described above. Figure 9 As discussed. In this embodiment, the resistance heating elements 342 at different locations on the article 300 can have different resistances, and therefore the resistance provided by the resistance heating element 342 can indicate the position of the resistance heating element on the article 300. Therefore, method 470 can be adjusted such that different control schemes are stored in memory 225 for each position of resistance heating element 342, and control system 222 can be configured to operate the device according to said control schemes. This embodiment may be advantageous because the resistance heating element near the mouthpiece of the article 300 may need to undergo a smaller degree of resistance heating (e.g., to prevent burns to the user's mouth). Therefore, the control scheme for the resistance heating element 342 near the mouthpiece can include instructions to apply a lower voltage to the article contact element 322.

[0256] The applicant recognizes that determining the resistance is not the only mechanism for determining the type 300 article inserted into the device. Figure 32 Another aerosol supply device 200 and two different articles suitable for use with the device 200 are schematically shown, namely a first article 300a and a second article 300b. Articles 300a and 300b each include first article electrical contacts 360a and 360b and second article electrical contacts 365a and 365b, respectively. The first article electrical contacts 360a and 360b and the second article electrical contacts 365a and 365b are article electrical contacts 322. Articles 300a and 300b also each include a resistive element 342, in... Figure 32In this embodiment, the resistive element can be a resistance heating element 342. The first electrical contacts 360a and 360b and the second electrical contacts 365a and 365b enable electrical connection between the resistance heating element 342. The resistance heating element 342 can be arranged to heat the aerosol-generating material 302 present on the articles 300a and 300b.

[0257] In some implementations, such as Figure 32 As shown, the first product electrical contacts 360a and 360b are located at different positions on products 300a and 300b, and / or the second product electrical contacts 365a and 365b are located at different positions on products 300a and 300b. The first product electrical contacts 360a and 360b and the second product electrical contacts 365a and 365b may, for example, have different positions along the length of the respective products 300a and 300b, and / or have different positions around the respective products, and / or have different positions on different sides of the respective products.

[0258] The aerosol supply device 200 includes a product receiving portion 206, which is shaped to receive a product 300 in use. The aerosol supply device 200 may include an electrical connector 230 comprising a plurality of device electrical contacts 232a, 232b (e.g., connector electrical contacts), such as two sets of device electrical contacts, which are configured to engage with product electrical contacts 322. More specifically, device electrical contacts 232a are configured to engage with a first product electrical contact 360a and a second product electrical contact 365a of product 300a, and device electrical contacts 232b are configured to engage with a first product electrical contact 360b and a second product electrical contact 365b of product 300b. Device electrical contacts 232 can provide power to product electrical contacts 322, such that power can be provided to a resistance heating element 342 to heat the aerosol generating material 302.

[0259] The aerosol supply device 200 also includes a control system 222, which may include a processor 223 and a memory 225. The control system 222 may be configured to determine during use which of the device electrical contacts 232a, 232b has engaged with the article electrical contact 322, and to control the operation of the aerosol supply device 200 based on the determination result. In other words, the control system 222 is able to determine which device electrical contacts 232a, 232b the inserted article 300 has established an electrical connection with. Therefore, the article 300 inserted into the article receiving portion 206 can be identified via the position of the article electrical contact 322 on the article 300 (e.g., article electrical contact position marking). When the articles 300a, 300b are received in the article receiving portion 206, the article electrical contact 322a or 322b together with the device electrical contacts 232a or 232b form a closed circuit. It is possible to determine which device electrical contacts 232a, 232b and product electrical contacts 322a, 322b are engaged based on which circuits are closed.

[0260] The control system 222 can be configured to measure the resistance at the electrical contacts 232a and 232b of the device, and if the resistance is infinitely large, determine that the electrical contacts 232a and 232b of the device have not yet engaged with the electrical contacts of the product. In some embodiments, the control system 222 can be configured to measure the current flowing through the electrical contacts 232a and 232b of the device, and if the current is not equal to zero, determine that the electrical contacts 232a and 232b of the device have engaged with the electrical contacts of the product.

[0261] The fact that the position of the electrical contact portion 322 of the product is different between the first product 300a and the second product 300b can be used to identify different products 300 and adjust the operation of the device 200 according to the product 300 being used.

[0262] In some embodiments, the memory 225 of the control system may store multiple control schemes. Each control scheme may correspond to a different article 300 and is therefore associated with an article electrical contact position mark specific to that article type. Each control scheme may include information such as operating voltage, indication information (e.g., informing the user that article type B has been inserted), etc. Thus, the operation of the device 200 can be adjusted according to the control scheme depending on the article 300 inserted into the article receiving portion 206.

[0263] Figure 33 It is a flowchart illustrating the operations. Figure 32Method 480 of the aerosol supply device 200 shown. In step 482, the position of the product electrical contact 322 is determined by determining which of the device electrical contacts 232a, 232b engage with the product electrical contact 322 (i.e., product contacts 360a, 360b, 365a, 365b). In step 484, the determined product contact element position is compared with a product contact element position mark stored in memory 225 to match the determined product contact element position with one of the stored product contact element position marks.

[0264] In step 486, after the determined product contact element position matches one of the stored product contact element position marks, the control system 222 controls the operation of the device 200 according to the control scheme associated with the product contact element position mark.

[0265] It should be understood that the features of the embodiments described herein can be combined. For example, device 200 may simultaneously use method 470 to identify article 300 inserted into article receiving portion and method 450 to ensure that device 200 does not perform unsafe operations.

In some embodiments, the resistance heating element extends within the aerosol-generating section. The resistance heating element may extend around the aerosol-generating section. In some embodiments, the resistance heating element surrounds the aerosol-generating section. In some configurations, at least a portion of the flow path through the article passes through the aerosol-generating section. The aerosol-generating section may define a portion of an air path. In some embodiments, first-type electrical contacts and second-type electrical contacts are exposed from the aerosol-generating section.

This recombination process is similar to papermaking.
