[0002] This application claims priority to and the benefit of U.S. Patent Application No. 16 / 260,712, filed on January 29, 2019, entitled “Susceptor Arrangement for Induction-Heated Aerosol Delivery Device,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to aerosol source components, aerosol delivery articles and their use in producing tobacco components or other materials in an inhalable form. More specifically, the present disclosure relates to aerosol source components such as smoking articles and aerosol delivery devices and systems that utilize electrically generated heat to heat tobacco or tobacco-derived materials, preferably without significant combustion, to provide an inhalable substance in an aerosol form for human consumption. Background Art

[0004] In recent years, many smoking articles have been proposed as improvements or alternatives to smoking products based on burning tobacco. Exemplary alternatives have included devices in which solid or liquid fuels are burned to transfer heat to the tobacco, or in which chemical reactions are used to provide such heat sources. Examples include smoking articles described in U.S. Pat. No. 9,078,473 to Worm et al., which is incorporated herein by reference in its entirety.

[0005] The purpose of the improvement or alternative of smoking articles is usually to provide the feeling related to cigarette, cigar or pipe smoking, without transmitting a large amount of incomplete combustion and pyrolysis products. For this reason, it has been proposed to adopt electric energy to evaporate or heat volatile materials or to attempt to provide the feeling of smoking cigarettes, cigars or pipes without burning tobacco to a significant degree of many cigarette products, flavor generators and drug inhalers. For example, referring to the various alternative smoking articles, aerosol delivery devices and heating sources described in the background technology described in the U.S. Patent No. 7,726,320 and the U.S. Patent Application Publication No. 2013 / 0255702 of Griffith Jr. et al. and the U.S. Patent Application Publication No. 2014 / 0096781 of Sears et al., the above-mentioned documents are incorporated herein by reference in their entirety.

[0053] The present disclosure will now be described more completely below with reference to exemplary embodiments of the present disclosure. These exemplary embodiments are described so that the present disclosure will be detailed and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. In fact, the present disclosure can be implemented in many forms and should not be understood as being limited to the various embodiments set forth herein; on the contrary, these embodiments are provided so that the present disclosure will meet applicable legal requirements. As used in this specification and the appended claims, the singular forms "one", "one / kind", "the" and similar terms include indications of the plural, unless otherwise clearly stated in the text. Moreover, although quantitative measurements, numerical values, geometric relationships, etc. may be referred to herein, any one of these, or if not all, may be absolute or approximate, unless otherwise stated, to take into account acceptable changes that may occur, such as those caused by engineering tolerances, etc.

[0054] As described below, exemplary embodiments of the present disclosure relate to aerosol delivery devices. Aerosol delivery devices according to the present disclosure use electrical energy to heat a material (preferably without burning the material to any significant extent) to form an inhalable substance; components of such a system are in the form of an article, most preferably, the article is compact enough to be considered a handheld device. That is, the aerosol is primarily derived from the generation of smoke from the byproducts of the combustion or pyrolysis of tobacco, in the sense that the use of the components of the preferred aerosol delivery device does not result in the generation of smoke, but rather the use of those preferred systems results in the generation of vapor, which is caused by the volatilization or evaporation of certain components therein. In some exemplary embodiments, the components of the aerosol delivery device can be characterized as electronic cigarettes, and those electronic cigarettes most preferably contain tobacco and / or components derived from tobacco, and thus deliver tobacco-derived components in the form of an aerosol.

[0055] The aerosol generating components of certain preferred aerosol delivery devices can provide many of the sensations of smoking a cigarette, cigar, or pipe (e.g., the habit of inhaling and exhaling, the variety of flavors or aromas, the sensory effects, the physical sensations, the habit of use, the visual cues provided by the visible aerosol, etc.), without burning any of the components to a significant degree, whereas these cigarettes, cigars, or pipes are used by lighting and burning tobacco (and thus inhaling tobacco smoke). For example, a user of an aerosol delivery device according to some exemplary embodiments of the present invention can hold and use the component like a smoker uses a traditional type of smoking article, inhale on one end of the article to inhale the aerosol generated by the article, and take puffs or inhales at selected time intervals, etc.

[0056] Although the system is generally described herein from the perspective of embodiments associated with aerosol delivery devices such as so-called "electronic cigarettes" or "tobacco heating products", it should be understood that the mechanisms, components, features, and methods can be implemented in many different forms and associated with a variety of different products. For example, the description provided herein can be used in conjunction with embodiments of traditional smoking articles (e.g., cigarettes, cigars, pipes, etc.), heat-not-burn cigarettes, and related packaging for any product disclosed herein. Therefore, it should be understood that the mechanisms, components, features, and methods disclosed herein are discussed only by way of example from the perspective of embodiments associated with aerosol delivery devices, and can be implemented as and used for a variety of other products and methods.

[0057] The aerosol delivery device of the present disclosure can also be characterized as a vapor-generating article or a medicament delivery article. Therefore, such articles or devices can be modified to provide one or more substances (e.g., fragrance and / or medicine or nutritional active ingredients) in an inhalable form or state. For example, an inhalable substance can be in the form of a vapor (i.e., a substance in a gas phase at a temperature below the critical point). Alternatively, an inhalable substance can be in the form of an aerosol (i.e., a suspension of fine solid particles or droplets in a gas). For the purpose of simplification, the term "aerosol" used herein is intended to include vapor, gas or aerosol in a form or type suitable for human inhalation, whether visible or not, and whether it can be considered as a smoke-like form. The physical form of the inhalable substance is not necessarily limited by the properties of the device of the present invention, but can depend on the properties of the medium and whether the inhalable substance itself exists in a vapor state or an aerosol state. In some embodiments, the terms "vapor" and "aerosol" can be interchanged. Therefore, for simplicity, unless otherwise stated, the terms "vapor" and "aerosol" used to describe various aspects of the present disclosure should be understood to be interchangeable.

[0058] When in use, the aerosol delivery device of the present disclosure can be subjected to many of the body movements that an individual employs when using a traditional type of smoking article (e.g., a cigarette, cigar, or pipe for lighting and inhaling tobacco). For example, a user of the aerosol delivery device of the present disclosure can hold the article as if holding a traditional type of smoking article, inhale on one end of the article to inhale the aerosol generated by the article, and inhale at selected time intervals, etc.

[0059] The aerosol delivery device of the present disclosure generally includes a plurality of components disposed within an outer body or shell, which may be referred to as a shell. The overall design of the outer body or shell may vary, and the form or construction of the outer body that is capable of defining the overall size and shape of the aerosol delivery device may vary. Typically, an elongated body having a shape similar to that of a cigarette or cigar may be formed by a single integral shell, or the elongated shell may be formed by two or more separable bodies. For example, the aerosol delivery device may include an elongated shell or body that may be generally tubular in shape and thereby resemble the shape of a conventional cigarette or cigar. In another example, the aerosol delivery device may be substantially rectangular or have a substantially rectangular cuboid shape (e.g., similar to a USB flash drive). In one example, all components of the aerosol delivery device are contained within a shell. Alternatively, the aerosol delivery device may include two or more shells that are connected and separable. For example, an aerosol delivery device may have a control body at one end, the control body including a housing that houses one or more reusable components (e.g., a battery such as a rechargeable battery and / or a rechargeable supercapacitor, and various electronic components for controlling the operation of the product), and the smoking article may be detachably connected to an outer body or shell at the other end, the outer body or shell housing a disposable portion (e.g., a disposable flavoring cartridge containing aerosol precursor materials, flavors, etc.). More specific forms, constructions, and configurations of components within a single-shell type unit or a multi-piece detachable shell type unit will be apparent from the further disclosure provided herein. In addition, the designs and component configurations of various aerosol delivery devices may be understood in light of commercially available electronic aerosol delivery devices.

[0060] As will be discussed in more detail below, the aerosol delivery device of the present disclosure includes a power source (e.g., a power supply), at least one control component (e.g., a device for actuating, controlling, regulating, and stopping the power for heating, such as by controlling the current flowing from the power source to other components of the article, such as a microprocessor alone or as part of a microcontroller), a heater or heating element (e.g., a resistive heating element or other component, and / or an induction winding or other related component, and / or one or more radiant heating elements), and an aerosol source member including or containing a substrate portion that is capable of generating an aerosol when sufficient heat is applied. In some embodiments, the aerosol source member may include a mouth end or end configured to allow inhalation on the aerosol delivery device to inhale the aerosol (e.g., a defined airflow path through the article so that the generated aerosol can be drawn out of the path during inhalation). In other embodiments, the control body may include a mouthpiece configured to allow inhalation for aerosol inhalation.

[0061] The alignment of the components within the aerosol delivery device of the present disclosure may vary. In a specific embodiment, the aerosol source component or the substrate portion of the aerosol source component may be positioned near the heating component so as to maximize the delivery of aerosol to the user. However, other configurations are not excluded. Typically, the heating component may be positioned close enough to the aerosol source component or the substrate portion of the aerosol source component so that the heat from the heating component can volatilize the aerosol source component or the substrate portion of the aerosol source component (and in some embodiments, one or more flavors, drugs, etc. that may also be provided to be delivered to the user) and form an aerosol for delivery to the user. When the heating element heats the substrate portion of the aerosol source component or the aerosol source component, the aerosol is formed, released or generated in a physical form suitable for inhalation by the consumer. It should be noted that the aforementioned terms are intended to be interchangeable, so that the release, being released, will release or release (released) mentioned include formation or generation, being formed or being generated, will form or will generate and after formation (formed) or generation (generated). In particular, the inhalable substance is released in the form of a vapor, or an aerosol, or a mixture of vapor and aerosol, wherein these terms are also used interchangeably herein unless otherwise stated.

[0062] As described above, the aerosol delivery device of various embodiments may include a power source (e.g., a battery or other power source) to provide current sufficient to provide various functions to the aerosol delivery device, such as powering a heating member, powering an induction winding, powering a control system, and powering an indicator, etc. The power source can take various embodiments. Preferably, the power source is capable of delivering sufficient power to quickly activate the heating source, thereby providing aerosol formation and powering the aerosol delivery device by using it for a desired duration. The power source is preferably sized to fit conveniently within the aerosol delivery device so that the aerosol delivery device can be easily handled. In addition, the preferred power source is light enough so as not to detract from the desired smoking experience.

[0063] More specific forms, configurations, and arrangements of components within the disclosed aerosol delivery device will be apparent from the further disclosure provided below. In addition, the selection of various aerosol delivery device components may be understood in light of commercially available electronic aerosol delivery devices. Further, the arrangement of components within the aerosol delivery device may also be understood in light of commercially available electronic aerosol delivery devices.

[0064] As described above, the aerosol delivery device may be configured to heat the aerosol source member or the substrate portion of the aerosol source member to produce an aerosol. In some embodiments, the aerosol delivery device may include a heating but not burning device, which is configured to heat an extruded structure and / or substrate, a substrate material associated with an aerosol precursor composition, a solid or liquid form (e.g., beads, shreds, wrapping paper, fiber sheets or paper) tobacco and / or tobacco-derived materials (i.e., materials found naturally in tobacco, that is, directly isolated or synthetically prepared from tobacco) or the like. Such an aerosol delivery device may include a so-called electronic cigarette.

[0065] Regardless of the type of heated substrate material, some aerosol delivery devices may include a heating component configured to heat an aerosol source component or a substrate portion of an aerosol source component. In some devices, the heating component may include a resistive heating component. The resistive heating component may be configured to generate heat when an electric current is directed through it. Such heating components typically include a metallic material and are configured to generate heat due to the resistance associated with passing an electric current. Such a resistive heating component may be positioned near the aerosol source component or the substrate portion of the aerosol source component. Alternatively, the heating component may be positioned in contact with a solid or semi-solid aerosol precursor composition. Such a configuration may heat the aerosol source component or the substrate portion of the aerosol source component to generate an aerosol. Representative types of solid and semisolid aerosol precursor compositions and formulations are disclosed in U.S. Patent No. 8,424,538 to Thomas et al.; U.S. Patent No. 8,464,726 to Sebastian et al.; U.S. Patent Application Publication No. 2015 / 0083150 to Conner et al.; U.S. Patent Application Publication No. 2015 / 0157052 to Ademe et al.; and U.S. Patent Application Publication No. 14 / 755205 filed on June 30, 2015 by Nordskog et al., all of which are incorporated herein by reference in their entirety.

[0066] In the depicted embodiments, an induction heating configuration is used. In various embodiments, the induction heating configuration (induction heating device) may include a resonant transmitter and / or a resonant receiver (e.g., one or more receptors or multiple receptor particles). In this way, the operation of the aerosol delivery device may require directing an alternating current to the resonant transmitter to generate an oscillating magnetic field so as to induce eddy currents in the resonant receiver. In various embodiments, the resonant receiver may be a part of the aerosol source component or a substrate portion of the aerosol source component and / or may be configured near the aerosol source component or a substrate portion of the aerosol source component. The alternating current causes the resonant receiver to generate heat, thereby generating an aerosol from the aerosol source component. Some examples of various induction heating methods and configurations are described in U.S. Patent Application Publication No. 15 / 799,365, filed on October 31, 2017, entitled “Induction Heated Aerosol Delivery Device,” and U.S. Patent Application Publication No. 15 / 836,086, filed on December 8, 2017, entitled “Quasi-Resonant Flyback Converter for an Induction-Based Aerosol Delivery Device,” which are incorporated herein by reference in their entireties. Further examples of various induction-based control components and related circuits are described in U.S. Patent Application Publication No. 15 / 352,153, filed on November 15, 2016, entitled “Induction-Based Aerosol Delivery Device,” and U.S. Patent Application Publication No. 2017 / 0202266 to Sur et al., each of which is incorporated herein by reference in its entirety. It should be noted that while the depicted embodiment describes a single resonant launcher, in other embodiments, there may be multiple independent resonant launchers, such as embodiments having a segmented induction heating configuration.

The aerosol delivery device 100 may include a control body 102 and an aerosol source component 104. In various embodiments, the aerosol source component 104 and the control body 102 can be permanently or removably aligned in a functional relationship. In this regard, Figure 1 The aerosol delivery device 100 is shown in a coupled configuration, and Figure 2The aerosol delivery device 100 is shown in a separated configuration. Various mechanisms can connect the aerosol source member 104 to the control body 102 to produce a threaded fit, a press fit, an interference fit, a sliding fit, a magnetic fit, etc. In various embodiments, the control body 102 of the aerosol delivery device 100 can be substantially rod-shaped, substantially tubular, substantially rectangular or rectangular cube-shaped (e.g., similar to a USB flash drive) or substantially cylindrical. It should be noted that for the purposes of this disclosure, the term "substantially" should be understood as approximately and / or within a certain degree of manufacturing tolerance, as will be understood by those skilled in the art. In other embodiments, the control body can take another handheld shape, such as a small box shape, various electronic cigarettes (small cigarettes, large cigarettes) (e.g., one-piece) shapes, or a keychain shape.

[0068] In specific embodiments, one or both of the control body 102 and the aerosol source member 104 may be referred to as disposable or reusable. For example, the control body 102 may include replaceable or rechargeable batteries, solid-state batteries, thin-film solid-state batteries, rechargeable supercapacitors, etc., and thus be combined with any type of charging technology, including: connecting to a wall charger, connecting to a car charger (e.g., a cigarette lighter socket), connecting to a computer such as through a universal serial bus (USB) cable or connector (e.g., USB 2.0, 3.0, 3.1, USB Type-C), connecting to a USB connector (e.g., USB2.0, 3.0, 3.1, USB Type-C, which can be implemented in a wall socket, electronic device, vehicle, etc.), connecting to a solar panel connected to a photovoltaic cell (sometimes referred to as a solar cell) or solar cell, or a wireless charger such as a charger using inductive wireless charging (e.g., including wireless charging according to the Qi wireless charging standard of the Wireless Power Consortium (WPC)) or a wireless radio frequency (RF)-based charger, and connecting to an array of (one or more) external batteries such as a power bank to charge the device via a USB connector or a wireless charger. An example of an inductive wireless charging system is described in U.S. Patent Application Publication No. 2017 / 0112196 to Sur et al., which is incorporated herein by reference in its entirety. Further, in some embodiments, the aerosol source component 104 may include a disposable device. Disposable components for a control body are disclosed in U.S. Patent No. 8,910,639 to Chang et al., which is incorporated herein by reference in its entirety. In some embodiments, the control body 102 can be inserted into and / or connected to a separate charging station to charge the rechargeable battery of the device 100. In some embodiments, the charging station itself may include a rechargeable power source that charges the rechargeable battery of the device 100.

[0069] Reference Figure 2 , the figure shows Figure 1 100, wherein the aerosol source component 104 and the control body 102 are separated from each other, and the aerosol source component 104 of some embodiments may include a heating end 106 and a mouth end 108, the heating end is configured to be inserted into the control body 102, and the user inhales on the mouth end to generate an aerosol. In various embodiments, at least a portion of the heating end 106 may include a substrate portion 110. It should be noted that in other embodiments, the aerosol source component 104 does not necessarily include a heating end and / or a mouth end.

[0070] As noted above, the heating component of the depicted embodiment includes an induction heating arrangement. Figure 3 1 shows a schematic front view of an aerosol delivery device 100 according to an exemplary embodiment of the present disclosure. Generally speaking, the control body 102 of the depicted embodiment includes a resonant emitter, and the aerosol source component 104 includes a resonant receiver (e.g., one or more susceptors, or a plurality of susceptors), and the resonant emitter and the resonant receiver together cause heating of at least a portion of the aerosol source component 104 (e.g., the substrate portion 110). Although in various embodiments, the resonant emitter and / or the resonant receiver can take a variety of forms, in the embodiment of the present disclosure, the control body 102 includes a resonant emitter, and the aerosol source component 104 includes a resonant receiver (e.g., one or more susceptors, or a plurality of susceptors), and the resonant emitter and the resonant receiver together cause heating of at least a portion of the aerosol source component 104 (e.g., the substrate portion 110). Figure 3 In the particular embodiment depicted, the resonant radiator includes a spiral winding 128, which in some embodiments may surround a support cylinder 129, although in other embodiments, a support cylinder may not be required. In various embodiments, the resonant radiator may be made of one or more conductive materials, including, for example, silver, gold, aluminum, brass, zinc, iron, nickel, and alloys thereof, conductive ceramics such as yttrium-doped zirconium oxide, indium tin oxide, yttrium-doped titanate, and the like, and any combination of the foregoing materials. In the embodiment shown, the spiral winding 128 is made of a conductive metallic material such as copper. In other embodiments, the spiral winding may include a non-conductive insulating cover / wrapping material. Such materials may include, for example, one or more polymeric materials such as epoxy resins, silicone rubber, and the like, which may be helpful for low temperature applications, or fiberglass, ceramics, refractory materials, and the like, which may be helpful for high temperature applications.

[0071] As shown, the resonant emitter 128 may extend adjacent to the engagement end of the housing 118 and may be configured to substantially surround a portion of the heating end 106 of the aerosol source member 104 including the substrate portion 110. In this manner, the helical winding 128 of the illustrated embodiment may define a generally tubular configuration. In some embodiments, the support cylinder 129 may also define a tubular configuration and may be configured to support the helical winding 128 so that the helical winding 128 is close to but not in contact with the substrate portion 110. Thus, the support cylinder 129 may include a non-conductive material that may be substantially transparent to the oscillating magnetic field generated by the helical winding 128. In various embodiments, the helical winding 128 may be embedded in or otherwise coupled to the support cylinder 129. In the illustrated embodiment, the helical winding 128 is mated to the outer surface of the support cylinder 129; however, in other embodiments, the winding may be positioned at the inner surface of the support cylinder, fully embedded in the support cylinder, or have some other configuration.

[0072] As shown, the mouth end 108 of the aerosol source component 104 of some embodiments may include a filter 114, which may be made of, for example, cellulose acetate or polypropylene material. In various embodiments, the filter 114 may increase the structural integrity of the mouth end 108 of the aerosol source component 100, and / or provide filtering capabilities if desired, and / or provide resistance to suction. For example, the product according to the present invention can show a pressure drop of about 50 to about 250mm water pressure drop at an air flow rate of 17.5cc / second. In another embodiment, the pressure drop can be about 60mm to about 180mm, or about 70mm to about 150mm. The pressure drop value can be measured using a Filtrona filter test station (CTS series) available from Filtrona Instruments and Automation Ltd or a quality test module (QTM) obtained from the Cerulean Division of Molins, PLC. The thickness of the filter portion along the length of the mouth end of the aerosol source member can vary, for example, from about 2 mm to about 20 mm, from about 5 mm to about 20 mm, or from about 10 mm to about 15 mm. In some embodiments, the filter portion may include discrete sections. For example, some embodiments may include sections that provide filtering, sections that provide inhalation resistance, hollow sections that provide space for aerosol cooling, sections that provide increased structural integrity, other filter sections, or any one or any combination of the above.

[0073] In various embodiments, other components may be present between the substrate portion 110 and the mouth end 108 of the aerosol source member 104, wherein the mouth end 108 may include a filter portion 114. For example, in some embodiments, one or any combination of the following may be positioned between the substrate portion and the mouth end: an air gap; a phase change material for cooling air; a flavor release medium; an ion exchange fiber with selective chemical adsorption capability; aerogel particles as a filter medium; and other suitable materials.

[0074] As described above, various embodiments of the present disclosure employ an induction heating configuration to heat a portion of an aerosol source component, such as, for example, a substrate portion of the aerosol source component. The induction heating configuration may include at least one resonant transmitter and at least one resonant receiver (hereinafter also referred to as a susceptor, or more specifically, a plurality of susceptor particles). In different embodiments, the resonant transmitter may be located in a control body and a plurality of susceptor particles may be located in an aerosol source component. Additional possible components that may be included are described in U.S. Patent Application Publication No. 15 / 799,365, entitled “Induction Heated Aerosol Delivery Device,” filed on October 31, 2017, which is incorporated herein by reference in its entirety.

[0075] Back to Figure 3 , the control body 102 of the depicted embodiment may include: a housing 118 including an opening 119 defined in a mating end thereof; a flow sensor 120 (e.g., a suction sensor or a pressure switch); a control component 122 (e.g., a microprocessor alone or as part of a microcontroller, a printed circuit board (PCB) including a microprocessor and / or a microcontroller, etc.); a power source 124 (e.g., a rechargeable battery and / or a rechargeable supercapacitor); and an end cap that may include an indicator 126 (e.g., a light emitting diode (LED)).

[0076] Examples of possible power sources are described in U.S. Patent No. 9,484,155 to Peckerar et al. and U.S. Patent Application Publication No. 2017 / 0112191 filed on October 21, 2015 by Sur et al., the disclosures of which are each incorporated herein by reference in their entirety. With respect to the flow sensor 120, representative current regulating components and other current control components for aerosol delivery devices including various microcontrollers, sensors, and switches are described in U.S. Pat. Nos. 4,735,217 to Gerth et al., 4,922,901, 4,947,874, and 4,947,875 to Brooks et al., 5,372,148 to McCafferty et al., 6,040,560 to Fleischhauer et al., 7,040,314 to Nguyen et al., and 8,205,622 to Pan, all of which are incorporated herein by reference in their entirety. Reference may also be made to the control scheme described in U.S. Pat. No. 9,423,152 to Ampolini et al., which is incorporated herein by reference in its entirety. In one embodiment, the indicator 126 may include one or more light emitting diodes, quantum dot-based light emitting diodes, and the like. In some embodiments, the indicator 126 may be in communication with the control component 122 and, for example, when coupled to the control body 102 , illuminate when the flow sensor 120 detects that a user is inhaling on the aerosol source member 104 .

[0077] In some embodiments, an input element may be included in the aerosol delivery device (and may replace or supplement an airflow sensor or pressure sensor). In various embodiments, an input portion may be included to allow a user to control the function of the device and / or output information to the user. Any component or combination of components may be used as an input portion for controlling the function of the device. For example, as described in U.S. Patent Publication No. 2015 / 0245658 to Worm et al., one or more buttons may be used, the entire text of which is incorporated herein by reference. Similarly, as described in U.S. Patent Application Publication No. 2016 / 0262454 to Sears et al., a touch screen may be used, the entire text of which is incorporated herein by reference. As a further example, a component suitable for gesture recognition based on a specified movement of the aerosol delivery device may be used as an input portion. See U.S. Patent Application Publication No. 2016 / 0158782 to Henry et al., the entire text of which is incorporated herein by reference. As another example, a capacitive sensor may be implemented on the aerosol delivery device to enable a user to provide input, for example, by touching the surface of the device, on which the capacitive sensor is implemented.

[0078] Further other components may be employed in the aerosol delivery device of the present disclosure. For example, U.S. Pat. No. 5,154,192 issued to Sprinkel et al. discloses an indicator for a smoking article; U.S. Pat.

[0079] Other suitable current drive / release drive mechanisms may include temperature-actuated on / off switches or lip pressure-actuated switches, or touch sensors (e.g., capacitive touch sensors) configured to sense contact between a user (e.g., a user's mouth or finger) and one or more surfaces of an aerosol delivery device. An exemplary mechanism that can provide this suction actuation capability includes a 163PC01D36 silicon sensor manufactured by the MicroSwitch division of Honeywell, Inc. in Freeport, Illinois. With such a sensor, when a consumer inhales on the device, the heating member can be quickly activated by changes in pressure. In addition, flow sensing devices such as those using the hot wire anemometer principle can be used to cause the heating assembly to be energized quickly enough after sensing a change in air flow. Another available suction actuation switch is a pressure differential switch, such as the MPL-502-V model A from MicroPneumatic Logic, Fort Lauderdale, Florida. Another suitable suction actuation mechanism is a sensitive pressure sensor (e.g., equipped with an amplifier or gain stage), which is in turn coupled to a comparator to detect a predetermined threshold pressure. Another suitable suction actuation mechanism is a blade deflected by an airflow, the movement of which is detected by a motion sensing device. Another suitable actuation mechanism is a piezoelectric switch. Another available switch is a suitably connected Honeywell MicroSwitch Microbridge Airflow Sensor (Honeywell MicroSwitch Microbridge Airflow Sensor), part number AWM 2100V, from the MicroSwitch Division of Honeywell, Freeport, Illinois.

[0081] Figure 4 The exemplary embodiment according to the present disclosure is shown Figure 61. A cross-sectional view of a portion of a substrate portion 110 of an aerosol source member 104. In the described embodiment, the substrate portion 110 of the aerosol source member 104 includes a substrate material 148 consisting of a core portion 150, a surrounding portion 152, and a covering layer 154, wherein a plurality of susceptor particles 160 are dispersed within the substrate material 148. In the described embodiment, the substrate material 148 includes a single layer including the core portion 150 and the surrounding portion 152; however, in other embodiments (as will be described in detail below), the substrate portion 110 may include a layer having a core portion and a separate layer having a surrounding portion. In various embodiments, the plurality of susceptor particles include a resonant receiver configured for induction heating. In various embodiments, the substrate material 148 of the depicted embodiment may include a tobacco material. For example, in some embodiments, the tobacco material can include tobacco-containing beads, tobacco powder, tobacco shreds, tobacco rods, reconstituted tobacco materials, tobacco flakes, and combinations thereof, and / or finely ground tobacco, tobacco extracts, spray-dried tobacco extracts, or other tobacco forms mixed with optional inorganic materials (e.g., calcium carbonate), rice flour, corn flour, carboxymethyl cellulose (CMC), guar gum, sodium alginate, optional flavoring agents, and aerosol-forming materials to form a substantially solid, semi-solid, or formable (e.g., extrudable) substrate.

[0082] In the depicted embodiment, the core portion 150 is located at the approximate radial center of the substrate portion 110, and the peripheral portion 152 is disposed around the core portion 150. In various embodiments, the diameter of the core portion 150 is less than the overall diameter of the substrate portion 110 and can be expressed as a function of the overall diameter of the substrate portion. For example, in some embodiments, the diameter of the core portion can be about 1 / 8 to 3 / 4 of the overall diameter of the substrate portion, and in some embodiments can be about 1 / 4 to 1 / 2 of the overall diameter of the substrate portion of the aerosol source member. Similarly, the diameter of the peripheral portion 152 is less than the overall diameter of the substrate portion and can be expressed as a function of the diameter of the core portion. For example, in some embodiments, the diameter of the peripheral portion can be about 1.5 to 8 times the diameter of the core portion, and in some embodiments can be about 2 to 4 times the diameter of the core portion. In one case, the diameter of the core portion can be about 2 mm and the diameter of the peripheral portion can be within the range of about 6.5 mm to about 12 mm, inclusive.

[0083] In various embodiments, the core portion 150 of the substrate portion 110 may define a first susceptor particle distribution density, which may generally include the relative concentration of susceptor particles 160 within the core portion 150. Likewise, the peripheral portion 152 of the substrate portion 110 may define a second susceptor particle distribution density, which may generally include the relative concentration of susceptor particles 160 within the core portion 152. In various embodiments, the distribution density of susceptor particles can be defined in a number of different ways. For example, in some embodiments, the first distribution density may be defined as the volume of susceptor particles in the core portion as a function of the total volume of the core portion. Likewise, the second distribution density may be defined as the volume of susceptor particles in the peripheral portion as a function of the total volume of the peripheral portion. In other embodiments, the first distribution density may be defined as the volume of susceptor particles in the core portion as a function of the total volume of the substrate portion. Likewise, the second distribution density may be defined as the volume of susceptor particles in the peripheral portion as a function of the total volume of the substrate portion. In other embodiments, the first distribution density may be defined as the volume of susceptor particles in the core portion as a function of the total area of ​​the core portion across a cross-section of the substrate portion. Likewise, the second distribution density may be defined as the volume of the susceptor particles in the surrounding portion as a function of the total area of ​​the surrounding portion across the same cross-section of the substrate portion. In other embodiments where the susceptor particles have substantially the same size or fall within the same particle size range, the first distribution density may be defined as the number of susceptor particles in the core portion as a function of the volume of the core portion. Likewise, the second distribution density may be defined as the number of susceptor particles in the surrounding portion as a function of the volume of the surrounding portion.

[0084] Regardless of how the distribution density is calculated, the present invention provides that the first distribution density (the distribution density of the susceptor particles in the core portion) is greater than the second distribution density (the distribution density of the susceptor particles in the surrounding portion). In this way, the concentration of the susceptor particles in the core portion is higher than the concentration of the susceptor particles in the surrounding portion. It should be noted that in some embodiments, the distribution density of the surrounding portion may be substantially zero, and therefore, the core portion may include a plurality of susceptor particles, but the surrounding portion does not need to include a plurality of susceptor particles. In one embodiment, for example, the volume of the susceptor particles in the core portion may be in the inclusive range of about 4% to about 8% of the total volume of the substrate portion (including or excluding the cover portion), and the volume of the susceptor particles in the surrounding portion may be in the range of 0% to less than 4% of the total volume of the substrate portion (including or excluding the cover portion).

[0085] In some embodiments, the substrate material may include an extruded tobacco structure. For example, in some embodiments, the extruded structure may include or may be substantially composed of tobacco, tobacco-related materials, glycerol, water, adhesive materials and / or fillers and curing agents, such as one or more of calcium carbonate, rice flour, corn flour, etc. In various embodiments, suitable adhesive materials may include alginates, such as ammonium alginate, propylene glycol alginate, potassium alginate and sodium alginate. Alginates, particularly high viscosity alginate, can be used in conjunction with the controlled level of free calcium ions. Other suitable adhesive materials include hydroxypropyl cellulose, such as Klucel H from Aquaron; hydroxypropyl methylcellulose, such as Methocel K4MS from Dow Chemical; hydroxyethyl cellulose, such as Natrosol 250 MRCS from Aquaron; microcrystalline cellulose, such as Avicel from FMC; methylcellulose, such as MethocelA4M from Dow Chemical; sodium carboxymethyl cellulose, such as CMC 7HF and CMC 7H4F from Hercules Inc. Also having other possible binder materials comprises starch (for example corn starch), guar gum, carrageenan, locust bean gum, pectin and xanthan gum.In some embodiments, can adopt the combination or mixture of two or more binder materials.For example, in the U.S. Patent No. 5101839 authorizing Jakob et al. and the U.S. Patent No. 4924887 authorizing Raker et al., other examples of binder materials are described, and each document is included in this paper in full by referring to.In some embodiments, aerosol formation material can be provided as a part of binder material (for example, propylene glycol alginate).In addition, in some embodiments, binder material can comprise the nano cellulose derived from tobacco or other biomass.

[0086] In some embodiments, as described in U.S. Patent Application Publication No. 2012 / 0042885 of Stone et al., the substrate material may include an extruded material, which is incorporated herein in its entirety by reference. In yet another embodiment, the substrate material may include an extruded structure and / or substrate formed by pill-shaped (marumarized) tobacco and / or non-pill-shaped tobacco. Pill-shaped tobacco is known from, for example, U.S. Patent No. 5,105,831 granted to Banerjee et al., which is incorporated herein in its entirety by reference. Pill-shaped tobacco includes a tobacco mixture of about 20% to about 50% (weight) in powder form, glycerol (about 20% to about 30% weight), calcium carbonate (generally about 10% to about 60% weight, typically about 40% to about 60% weight) and an adhesive and / or flavoring as described herein. In various embodiments, the extruded material may have one or more longitudinal openings. In other embodiments, the extruded material may have two or more regions, for example, an extrudate with a wagon wheel-shaped cross section.

[0087] Additionally or alternatively, the substrate material may include an extruded structure and / or substrate, and is also configured to substantially maintain its structure throughout the aerosol generation process, the extruded structure and / or substrate including tobacco, glycerin, water and / or adhesive materials or consisting essentially of these materials. That is, throughout the aerosol generation process, the substrate material may be configured to substantially maintain its shape (i.e., the substrate material is discontinuously deformed under the applied shear stress). Although such exemplary substrate materials may include liquids and / or certain moisture contents, the substrate material may remain substantially solid throughout the aerosol generation process, and may substantially maintain structural integrity throughout the aerosol generation process. Exemplary tobacco and / or tobacco-related materials suitable for substantially solid substrate materials are described in U.S. Patent Application Publication No. 2015 / 0157052 to Ademe et al.; U.S. Patent Application Publication No. 2015 / 0335070 to Sears et al.; U.S. Patent No. 6,204,287 to White; and U.S. Patent No. 5,060,676 to Hearn et al., which are incorporated herein by reference in their entirety.

[0088] In other embodiments, the substrate material may include a flavorful and aromatic tobacco mixture in the form of shredded filler. In another embodiment, the substrate material may include a reconstructed tobacco material, such as in the U.S. Patent No. 4,807,809 granted to Pryor et al.; No. 4,889,143 granted to Pryor et al. and No. 5,025,814 granted to Raker, which are incorporated herein in their entirety by reference. In addition, the reconstructed tobacco material may include the reconstructed tobacco paper for cigarette types described in the RJReynolds Tobacco Company monograph (1988) "Chemical and Biological Research on the Heating of New Cigarette Prototypes of Substitute Burning Tobacco", which are incorporated herein in their entirety by reference. For example, the reconstructed tobacco material may include a sheet material containing tobacco and / or tobacco-related materials. Thus, in some embodiments, the substrate material may be formed by the reel of the reconstructed tobacco material. In another embodiment, the substrate material may be formed by shredded, striped and / or the like of the reconstructed tobacco material. In another embodiment, the tobacco sheet may include the curled sheet of the reconstructed tobacco material. In some embodiments, the substrate material may include overlapping layers (e.g., gathered webs) that may or may not include thermally conductive components. Examples of substrate materials including a series of overlapping layers (e.g., gathered webs) of an initial substrate sheet formed of a fiber filler material, an aerosol-forming material, and a plurality of thermally conductive components are described in U.S. Patent Application Publication No. 15 / 905,320, entitled "Heat Conducting Substrate for Electrically Heated Aerosol Delivery Device," filed on February 26, 2018, which is incorporated herein by reference in its entirety.

[0091] In various embodiments, the substrate material can have a variety of configurations based on the various materials used therein. For example, the sample substrate material can include tobacco and / or tobacco-related materials at most about 98% by weight, at most about 95% by weight, or at most about 90% by weight. The sample substrate material can also include water at most about 25% by weight, about 20% by weight, or about 15% by weight, specifically about 2% to about 25%, about 5% to about 20%, or about 7% to about 15% by weight of water. Flavoring agents, etc. (including, for example, drugs such as nicotine) can include at most about 10%, at most about 8%, or at most about 5% of the weight of the aerosol delivery component.

In various aspects of flame retardant, combustion and / or anti-scorch materials used in substrate materials and / or other components (whether used alone or in combination with each other and / or in combination with other materials), it is most preferred to provide the desired performance without undesirable degassing or melting-type behavior. Other examples include diammonium phosphate and / or other salts configured to help prevent the substrate material from being ignited, pyrolyzed, burned and / or scorched by a heat source. Various ways and methods of incorporating tobacco into smoking articles, particularly smoking articles designed not to intentionally burn substantially all of the tobacco in those smoking articles, are proposed in U.S. Patent Nos. 4,947,874 to Brooks et al.; 7,647,932 to Cantrell et al.; 8,079,371 to Robinson et al.; 7,290,549 to Banerjee et al.; and U.S. Patent Application Publication No. 2007 / 0215167 to Crooks et al.; the entire disclosures of the foregoing documents are incorporated herein by reference.

[0093] According to other embodiments of the present disclosure, the substrate material may also be combined with tobacco additive types traditionally used to make tobacco products. These additives may include the material type for enhancing the flavor and aroma of tobacco used to produce cigars, cigarettes, pipes, etc. For example, these additives may include various cigarette shells and / or dressing components. See, for example, U.S. Patent No. 3,419,015 to Wochnowski; U.S. Patent No. 4,054,145 to Berndt et al.; U.S. Patent No. 4,887,619 to Burcham et al.; U.S. Patent No. 5,022,416 to Watson; U.S. Patent No. 5,103,842 to Strang et al. and U.S. Patent No. 5,711,320 to Martin; Its disclosure is incorporated herein in its entirety by reference. Preferred shell materials may include water, sugar and syrup (e.g., sucrose, glucose and high fructose corn syrup), humectants (e.g., glycerol or propylene glycol) and flavorings (e.g., cocoa and licorice). Those added components may also include face covering materials (e.g., flavoring agents, such as menthol). See, for example, U.S. Pat. No. 4,449,541 to Mays et al., the disclosure of which is incorporated herein by reference in its entirety. Additional materials that may be added include those disclosed in U.S. Pat. No. 4,830,028 to Lawson et al. and U.S. Pat. No. 8,186,360 to Marshall et al., the disclosure of which is incorporated herein by reference in its entirety.

[0094] Various types of flavorings or the material that changes the sensation or organoleptic properties of the mainstream aerosol of smoking articles or properties are suitable for use. In some embodiments, such flavorings can be provided from sources other than tobacco, and can be natural or artificial. For example, some flavorings can be applied to or incorporated into those regions of the generation aerosol of substrate material and / or smoking articles. In some embodiments, such preparations can be directly supplied to a heating chamber or region near a heat source, or provided with substrate material. Exemplary flavorings can include, for example, vanillin, ethyl vanillin, cheese, tea, coffee, fruit (for example, apple, cherry, strawberry, peach and citrus flavor, including lime and lemon), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, cloves, lavender, cardamom, ginger, honey, fennel, sage, cinnamon, sandalwood, jasmine, West Indian bittersweet tree, cocoa beans, liquorice; and traditionally used as the spice type and characteristic spice and spice bag of cigarette, cigar and pipe tobacco. Syrups such as high fructose corn syrup may also be suitable for use.

[0095] Flavoring agent can also comprise acidity or alkaline characteristics (for example organic acid, such as levulinic acid, succinic acid, pyruvic acid and benzoic acid).In some embodiments, if desired, flavoring agent can be combined with the element of substrate material.In the U.S. Patent No. 9,107,453 and U.S. Patent Application Publication No. 2012 / 0152265 of Dube et al., disclose suitable exemplary plant-derived composition, its disclosure is included in this paper in full by referring to.Can be used in combination with tobacco material to affect its sensory characteristics including organoleptic characteristics such as flavoring agent, shell etc. any material can be combined with substrate material.Specifically, organic acid can be incorporated into substrate material to affect the local flavor, sensation or the organoleptic characteristics of the medicine such as nicotine that can be combined with substrate material.For example, organic acid such as levulinic acid, lactic acid and pyruvic acid can be included in tobacco substrate together with nicotine, and the amount of these organic acids and any combination of nicotine equimolar (based on total organic acid content) organic acid are all suitable. For example, in some embodiments, the substrate material may include about 0.1 to about 0.5 moles of levulinic acid per mole of nicotine, about 0.1 to about 0.5 moles of pyruvic acid per mole of nicotine, about 0.1 to about 0.5 moles of lactic acid per mole of nicotine, or a combination thereof, until a concentration is reached where the total amount of organic acid present therein is equimolar to the total amount of nicotine present in the substrate material. Various other examples of organic acids that can be used to generate substrate materials are disclosed in U.S. Patent Application Publication No. 2015 / 0344456 to Dull et al., which is incorporated herein by reference in its entirety.

[0096] The selection of these additional components may be variable based on factors such as the desired organoleptic properties of the smoking article, and the disclosure is intended to encompass any such additional components apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See "Tobacco Flavoring Substances and Methods" (1972) by Gutcho of Noyes Data Corp. and "Tobacco Flavoring for Smoking Products" (1972) by Leffingwell et al., the disclosures of which are incorporated herein by reference in their entirety.

[0097] In some embodiments, the substrate material may include other materials having various inherent characteristics or properties. For example, the substrate material may include a plasticized material in the form of rayon or regenerated cellulose. As another example, viscose fibers (such as commercially available ) is suitable, the viscose fiber being a regenerated cellulose product incorporating silica. Some carbon fibers may include at least 95% or more carbon. Similarly, natural cellulose fibers such as cotton are suitable and may be impregnated with silica, carbon or metal particles or otherwise treated with silica, carbon or metal particles to enhance flame retardancy and minimize off-gassing, especially any undesirable off-gas components that adversely affect flavor (especially minimizing the possibility of any toxic off-gas products). Cotton may be treated with, for example, boric acid or various organic phosphate compounds to provide the desired flame retardant properties by dipping, spraying or other techniques known in the art. These fibers may also be treated with organic or metal nanoparticles (by coating, impregnation or both, such as dipping, spraying or vapor deposition) to impart the desired flame retardancy without undesirable off-gassing or melt-type performance.

[0098] As mentioned above, the substrate material may also include an aerosol-forming material, such as an aerosol precursor composition. In some embodiments, the aerosol precursor composition may include one or more humectants, such as propylene glycol, glycerine and / or the like. In various embodiments, the amount of the aerosol precursor composition used in the aerosol delivery device may cause the aerosol delivery device to present acceptable sensory organs and sensory characteristics and desired performance characteristics. For example, in some embodiments, an aerosol precursor composition (such as, for example, glycerine and / or propylene glycol) may be used to produce a visible aerosol similar to the mainstream of tobacco smoke appearance in many respects. For example, the amount of the aerosol precursor composition incorporated into the substrate material of the smoking article may be in the range of about 4.5 grams or less, 3.5 grams or less, about 3 grams or less, about 2.5 grams or less, about 2 grams or less, about 1.5 grams or less, about 1 gram or less or about 5 grams. However, it should be noted that in other embodiments, values ​​outside these ranges are possible.

[0099] Representative types of other aerosol precursor compositions are described in U.S. Pat. No. 4,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jacob et al.; PCT WO 98 / 57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco (1988), a monograph by RJ Reynolds Tobacco Company; the disclosures of which are incorporated herein by reference. In some aspects, an aerosol source component can produce a visible aerosol when sufficient heat is applied thereto (and, if necessary, cooled with air), and the aerosol source component can produce a "smoke-like" aerosol. In other aspects, an aerosol source component can produce an aerosol that is substantially invisible but is identified as present by other characteristics such as flavor or mouthfeel. Thus, the properties of the generated aerosol may vary depending on the specific components of the aerosol delivery component.In various embodiments, the aerosol source component may be chemically simple relative to the chemical characteristics of the smoke generated by burning tobacco.

[0100] In some embodiments, an aerosol precursor composition, also referred to as a vapor precursor composition or "e-liquid," may include a variety of components, including, for example, a polyol (e.g., glycerol, propylene glycol, or a mixture thereof), nicotine, tobacco, tobacco extracts, and / or flavorants. Components and compositions of some possible types of aerosol precursors are described and characterized in U.S. Pat. No. 7,217,320 to Robinson et al., U.S. Pat. No. 2013 / 0008457 to Zheng et al., U.S. Pat. No. 2013 / 0213417 to Chong et al., U.S. Pat. No. 2014 / 0060554 to Collett et al., U.S. Pat. No. 2015 / 0030823 to Lipowicz et al., and U.S. Pat. No. 2015 / 0020830 to Koller, and WO 2014 / 182736 to Bowen et al., all of which are incorporated herein by reference. Other aerosol precursors that may be used include those contained in the following products: products; BLUTM products from Fontem Ventures BV; MISTIC MENTHOL products from MisticEcigs; MARK TEN products from Nu Mark LLC; JUUL products from Juul Labs; and VYPE products from CN Creative Ltd. Also possible are so-called “juices” for electronic cigarettes that are already available from Johnson Creek Enterprises LLC. Additional possible exemplary aerosol precursor compositions are sold under the following trade names: BLACK NOTE, COSMIC FOG, MILKMAN E-LIQUID, FIVE PAWNS, VAPOR CHEF, VAPE WILD, BOOSTED, THE STEAM FACTORY, MECH SAUCE, CASEY JONES MAINLINE RESERVE, DR. CRIMMY'S V-LIQUID, SMILEY E LIQUID, BEANTOWN VAPOR, CUTTWOOD, CYCLOPS VAPOR, SICBOY, GOOD LIFE VAPOR, TELEOS, PINUP VAPORS, SPACEJAM, MT. BAKER VAPOR, and JIMMY THE JUICE MAN.

[0101] The amount of aerosol precursor incorporated in the aerosol source member is such that the aerosol generating member provides acceptable sensory and desired performance characteristics. For example, it is desirable to use a sufficient amount of aerosol-forming material to generate a mainstream visible aerosol that is similar in many respects to the form of tobacco smoke. The amount of aerosol precursor in the aerosol generating system may depend on factors such as the number of puffs desired for each aerosol generating member. In one or more embodiments, an aerosol precursor composition of about 0.5 ml or more, about 1 ml or more, about 2 ml or more, about 5 ml or more, or about 10 ml or more may be included.

[0102] Return to reference Figure 4As described above, the core portion 150 and the surround portion 152 include a plurality of susceptor particles 160 that include a resonant receptor of the induction heating configuration of the depicted embodiment. In various embodiments, the plurality of susceptor particles 160 may have a variety of shapes, sizes, and materials, which in some embodiments may be combined in the same substrate portion. For example, in some embodiments, one or more of the plurality of susceptor particles 160 may have a substantially spherical shape, a plate-like shape, a substantially cubic shape, an irregular shape (e.g., a shape having one or more (e.g., a plurality) of sides, the sides having different sizes), or any combination thereof. In various embodiments, the plurality of susceptor particles 160 may include ferromagnetic materials, including, but not limited to, cobalt, iron, nickel, zinc, manganese, and any combination thereof. In additional embodiments, the plurality of susceptor particles 160 may include other materials, including, for example, other porous metal materials such as aluminum or stainless steel, as well as ceramic materials such as silicon carbide, carbon materials, and any combination of any of the foregoing. In yet another embodiment, the plurality of susceptor particles may include other conductive materials, including metals such as copper, alloys of conductive materials, or other materials in which one or more conductive materials are embedded. Although in various embodiments, the size of the porous susceptor particles may vary, in some embodiments, one or more of the plurality of porous susceptor carrier particles may have a diameter within an inclusive range of about 100 microns (0.1 mm) to about 2 mm, and in some embodiments, one or more of the plurality of porous susceptor particles may have a diameter within an inclusive range of about 0.5 mm to about 1.5 mm.

[0103] In the depicted embodiment, current changes in the spiral winding 128 (i.e., the resonant transmitter), such as current changes directed by the control component 122 (e.g., via a drive circuit) from the power source 124 to the spiral winding 128, can generate an alternating electromagnetic field that penetrates the plurality of susceptor particles 160 (i.e., the resonant receiver), thereby generating eddy currents within the plurality of susceptor particles 160. The alternating electromagnetic field can be generated by directing an alternating current to the spiral winding 128. As described above, in some embodiments, the control component 122 can include an inverter or inverter circuit configured to convert direct current provided by the power source into alternating current provided to the resonant transmitter.

[0104] The eddy currents flowing within the plurality of susceptor particles 160 may generate heat by the Joule effect, wherein the amount of heat generated is proportional to the square of the current multiplied by the resistance of the material of the plurality of susceptor particles 160. For embodiments in which the plurality of susceptor particles 160 include a ferromagnetic material, heat may also be generated by hysteresis losses. Several factors contribute to the increase in temperature of the plurality of susceptor particles 160, including, but not limited to, proximity to the helical winding 128, distribution of the magnetic field, resistivity of the material of the plurality of susceptor particles 160, saturation flux density, skin effect or depth, hysteresis losses, magnetic susceptibility, magnetic permeability, and dipole moment of the material.

[0105] In this regard and as described above, both the plurality of susceptor particles 160 and the spiral winding 128 may include a conductive material. For example, the spiral winding 128 and / or the plurality of susceptor particles 160 may include a variety of conductive materials, including metals such as copper or aluminum, alloys of conductive materials (e.g., diamagnetic, paramagnetic, or ferromagnetic materials), or other materials such as ceramics or glasses in which one or more conductive materials are embedded. In some embodiments, the plurality of susceptor particles may be coated with a thermally conductive passivation layer (e.g., a thin layer of glass) or otherwise include a thermally conductive passivation layer.

[0106] In some embodiments, the plurality of porous susceptor particles 160 contained in the aerosol source member 104 may be supplemented by additional / alternative resonant receivers. For example, in some embodiments, the control body 102 of the device 100 may include a separate resonant receiver, such as, for example, one or more receiver pins. Some examples of suitable components are described in U.S. Patent Application Publication No. 15 / 799,365, entitled “Induction Heated Aerosol Delivery Device,” filed on October 31, 2017, which is incorporated herein by reference in its entirety.

[0107] Return to reference Figure 4, the substrate portion 110 of some embodiments may also include a covering layer 154 arranged around the peripheral portion 152. In the depicted embodiment, the covering layer 154 includes a foil sublayer 156 and a paper sublayer 158, wherein the paper sublayer 158 is arranged around the foil sublayer 156. In some embodiments, the foil sublayer and the paper sublayer may include a single laminate. In some embodiments, the paper sublayer may include paper or other fiber materials, such as cellulose materials. The paper sublayer material may also include at least one filler material embedded or dispersed in the fiber material. In various embodiments, the filler material may have the form of particles that are insoluble in water. In addition, the filler material may be combined with an inorganic component. In some embodiments, the paper sublayer may be formed by multiple layers, such as a loose layer below and a layer such as a typical wrapping paper in a cigarette above. Such materials may include, for example, lightweight "rag-like fibers", such as flax, hemp, sisal, straw and / or spathiphyllum. Various types of paper materials are described in U.S. Pat. Nos. 5,105,838 to White et al.; 5,271,419 to Arzonico et al.; 5,220,930 to Gentry; 6,908,874 to Woodhead et al.; 6,929,013 to Ashcraft et al.; 7,195,019 to Hancock et al.; 7,276,120 to Holmes; 7,275,548 to Hancock et al.; PCT WO 01 / 08514 to Fournier et al.; and PCT WO 03 / 043450 to Hajaligol et al., all of which are incorporated herein by reference in their entirety. In some embodiments, the paper material may include materials such as RJ Reynolds Tobacco Company Grades 119, 170, 419, 453, 454, 456, 465, 466, 490, 525, 535, 557, 652, 664, 672, 676, and 680, which are commercially available from Schweitzer-Maudit International. In the depicted embodiment, the foil sublayer 152 includes a metal foil material, such as an aluminum foil material. However, in other embodiments, the foil sublayer may include other materials, including but not limited to copper materials, tin materials, gold materials, graphene materials, graphite materials, or other thermally conductive carbon-based materials, and / or any combination thereof. Although various thicknesses are possible, in some embodiments, the cover layer may have a thickness within an inclusive range of about 1 mm to about 3 mm.

[0108] exist Figure 5An alternative embodiment of the present disclosure is shown in FIG. Figure 5 FIG. 2 shows a cross-sectional view of a portion of a substrate portion 210 of an aerosol source member according to another exemplary embodiment of the present disclosure. Figure 5 The aerosol source member of the substrate portion 210 can be used for various control subjects, such as for example Figure 1-3 and 10 control body. In the depicted embodiment, the substrate portion 210 of the aerosol source member includes a plurality of layers. For example, in the depicted embodiment, the substrate portion 210 includes a first layer 235 and a second layer 245, the first layer including a core portion 250, and the second layer including a peripheral portion 252. In the depicted embodiment, the first layer 235 is located at the approximate radial center of the substrate portion 210, and the second layer 245 is disposed around the first layer 235. In some embodiments, the diameter of the first layer 235 is less than the overall diameter of the substrate portion 210 and can be expressed as a function of the overall diameter of the substrate portion. For example, in some embodiments, the diameter of the core portion can be about 1 / 8 to 3 / 4 of the overall diameter of the substrate portion, and in some embodiments can be about 1 / 4 to 1 / 2 of the overall diameter of the substrate portion of the aerosol source member. Similarly, the diameter of the peripheral portion 152 is less than the overall diameter of the substrate portion and can be expressed as a function of the diameter of the core portion. For example, in some embodiments, the diameter of the peripheral portion can be about 1.5 to 8 times the diameter of the core portion, and in some embodiments can be about 2 to 4 times the diameter of the core portion. In one case, the diameter of the core portion can be about 2 mm and the diameter of the peripheral portion can be in the range of about 6.5 mm to about 12 mm, inclusive.

[0109] In various embodiments, the first layer 235 including the core portion 250 may define a first susceptor particle distribution density, which may generally include the relative concentration of susceptor particles within the first layer 235. Likewise, the second layer 245 including the peripheral portion 252 may define a second susceptor particle distribution density, which may generally include the relative concentration of susceptor particles within the second layer 245. In various embodiments, the distribution density of susceptor particles can be defined in a number of different ways. For example, in some embodiments, the first distribution density may be defined as the volume of susceptor particles in the first layer as a function of the total volume of the first layer. Likewise, the second distribution density may be defined as the volume of susceptor particles in the second layer as a function of the total volume of the second layer. In other embodiments, the first distribution density may be defined as the volume of susceptor particles in the first layer as a function of the total volume of the substrate portion. Likewise, the second distribution density may be defined as the volume of susceptor particles in the second layer as a function of the total volume of the substrate portion. In other embodiments, the first distribution density may be defined as the volume of susceptor particles in the first layer as a function of the total area of ​​the cross-section of the first layer across the substrate portion. Likewise, the second distribution density may be defined as the volume of the susceptor particles in the second layer as a function of the total area of ​​the second layer across the same cross-section of the substrate portion. In other embodiments where the susceptor particles have substantially the same size or fall within the same particle size range, the first distribution density may be defined as the number of susceptor particles in the first layer as a function of the volume of the first layer. Likewise, the second distribution density may be defined as the number of susceptor particles in the second layer as a function of the volume of the second layer.

[0110] Regardless of how the distribution density is calculated, the present invention provides that the first distribution density (the distribution density of the susceptor particles in the first layer including the core portion) is greater than the second distribution density (the distribution density of the susceptor particles in the second layer including the peripheral portion). In this manner, the concentration of the susceptor particles in the core portion is higher than the concentration of the susceptor particles in the peripheral portion. It should be noted that in the depicted embodiment, the susceptor particles 260 of the first layer 235 and the susceptor particles 262 of the second layer 245 include substantially the same type of particles (e.g., substantially the same material); however, in other embodiments, the type of susceptor particles of the first layer may be different from the type of susceptor particles of the second layer. In still other embodiments, the first layer may include a plurality of susceptor particles, but the second layer need not include a plurality of susceptor particles. In one embodiment, for example, the volume of the susceptor particles in the first layer may be in the range of about 4% to about 8% inclusive of the total volume of the substrate portion (including or excluding the cover portion), and the volume of the susceptor particles in the second layer may be in the range of 0% to less than 4% of the total volume of the substrate portion (including or excluding the cover portion).

[0111] In the depicted embodiment, the first layer 235 and / or the second layer 245 may include a substrate material. In some embodiments, the substrate material may include an extruded tobacco structure. For example, in some embodiments, the extruded structure may include or may be substantially composed of tobacco, tobacco-related materials, glycerine, water, adhesive materials and / or fillers and curing agents, such as one or more of calcium carbonate, rice flour, corn flour, etc. In various embodiments, suitable adhesive materials may include alginate, such as ammonium alginate, propylene glycol alginate, potassium alginate and sodium alginate. Alginate, specifically high viscosity alginate can be used in conjunction with the controlled level of free calcium ions. Other suitable binder materials include hydroxypropyl cellulose, such as Klucel H from Aquaron; hydroxypropyl methylcellulose, such as Methocel K4MS from Dow Chemical; hydroxyethyl cellulose, such as Natrosol 250 MRCS from Aquaron; microcrystalline cellulose, such as Avicel from FMC; methyl cellulose, such as Methocel A4M from Dow Chemical; sodium carboxymethyl cellulose, such as CMC 7HF and CMC 7H4F from Hercules Inc. Still other possible binder materials include starch (e.g., corn starch), guar gum, carrageenan, locust bean gum, pectin, and xanthan gum. In some embodiments, a combination or mixture of two or more binder materials may be used. Other examples of binder materials are described in, for example, U.S. Patent No. 5,101,839 to Jakob et al. and U.S. Patent No. 4,924,887 to Raker et al., each of which is incorporated herein by reference in its entirety. In some embodiments, the aerosol-forming material may be provided as part of a binder material (eg, propylene glycol alginate). In addition, in some embodiments, the binder material may include nanocellulose derived from tobacco or other biomass.

[0112] In some embodiments, as described in the U.S. Patent Application Publication No. 2012 / 0042885 of Stone et al., the substrate material may include an extruded material, which is incorporated herein in its entirety by reference. In yet another embodiment, the substrate material may include an extruded structure and / or substrate formed by pelletized tobacco and / or non-pelletized tobacco. Pellets are known from, for example, U.S. Patent No. 5,105,831 granted to Banerjee et al., which is incorporated herein in its entirety by reference. Pellets include a tobacco mixture of about 20% to about 50% (weight) in powder form, glycerol (about 20% to about 30% weight), calcium carbonate (generally about 10% to about 60% weight, typically about 40% to about 60% weight) and an adhesive and / or flavoring as described herein. In various embodiments, the extruded material may have one or more longitudinal openings. In other embodiments, the extruded material may have two or more regions, for example, an extrudate with a truck wheel-shaped cross section.

[0113] Additionally or alternatively, the substrate material may include an extruded structure and / or substrate, and is also configured to substantially maintain its structure throughout the aerosol generation process, the extruded structure and / or substrate including tobacco, glycerin, water and / or adhesive materials or consisting essentially of these materials. That is, throughout the aerosol generation process, the substrate material may be configured to substantially maintain its shape (i.e., the substrate material is discontinuously deformed under the applied shear stress). Although such exemplary substrate materials may include liquids and / or certain moisture contents, the substrate material may remain substantially solid throughout the aerosol generation process, and may substantially maintain structural integrity throughout the aerosol generation process. Exemplary tobacco and / or tobacco-related materials suitable for substantially solid substrate materials are described in U.S. Patent Application Publication No. 2015 / 0157052 to Ademe et al.; U.S. Patent Application Publication No. 2015 / 0335070 to Sears et al.; U.S. Patent No. 6,204,287 to White; and U.S. Patent No. 5,060,676 to Hearn et al., which are incorporated herein by reference in their entirety.

[0114] In other embodiments, the substrate material may include a flavorful and aromatic tobacco mixture in the form of shredded filler. In another embodiment, the substrate material may include a reconstructed tobacco material, such as in the U.S. Patent No. 4,807,809 granted to Pryor et al.; No. 4,889,143 granted to Pryor et al. and No. 5,025,814 granted to Raker, which are incorporated herein in their entirety by reference. In addition, the reconstructed tobacco material may include the reconstructed tobacco paper for cigarette types described in the RJReynolds Tobacco Company monograph (1988) "Chemical and Biological Research on the Heating of New Cigarette Prototypes of Substitute Burning Tobacco", which are incorporated herein in their entirety by reference. For example, the reconstructed tobacco material may include a sheet material containing tobacco and / or tobacco-related materials. Thus, in some embodiments, the substrate material may be formed by the reel of the reconstructed tobacco material. In another embodiment, the substrate material may be formed by shredded, striped and / or the like of the reconstructed tobacco material.

Other examples include diammonium phosphate and / or other salts configured to help prevent the substrate material from being ignited, pyrolyzed, burned and / or scorched by a heat source. Various ways and methods of incorporating tobacco into smoking articles, particularly smoking articles designed not to intentionally burn substantially all of the tobacco in those smoking articles, are proposed in U.S. Patent Nos. 4,947,874 to Brooks et al.; 7,647,932 to Cantrell et al.; 8,079,371 to Robinson et al.; 7,290,549 to Banerjee et al.; and U.S. Patent Application Publication No. 2007 / 0215167 to Crooks et al.; the entire disclosures of the foregoing documents are incorporated herein by reference.

[0119] According to other embodiments of the present disclosure, the substrate material may also be combined with tobacco additive types traditionally used to make tobacco products. These additives may include the material type for enhancing the flavor and aroma of tobacco used to produce cigars, cigarettes, pipes, etc. For example, these additives may include various cigarette shells and / or dressing components. See, for example, U.S. Patent No. 3419015 granted to Wochnowski; U.S. Patent No. 4054145 granted to Berndt et al.; U.S. Patent No. 4887619 granted to Burcham et al.; U.S. Patent No. 5022416 granted to Watson; U.S. Patent No. 5103842 granted to Strang et al. and U.S. Patent No. 5711320 granted to Martin; Its disclosure is incorporated herein in its entirety by reference.

No. 4,830,028 to Lawson et al. and U.S. Pat. No. 8,186,360 to Marshall et al., the disclosure of which is incorporated herein by reference in its entirety.

[0120] Various types of flavorings or the material that changes the sensation or organoleptic properties of the mainstream aerosol of smoking articles or properties are suitable for use. In some embodiments, such flavorings can be provided from sources other than tobacco, and can be natural or artificial. For example, some flavorings can be applied to or incorporated into those regions of the generation aerosol of substrate material and / or smoking articles. In some embodiments, such preparations can be directly supplied to a heating chamber or region near a heat source, or provided with substrate material. Exemplary flavorings can include, for example, vanillin, ethyl vanillin, cheese, tea, coffee, fruit (for example, apple, cherry, strawberry, peach and citrus flavor, including lime and lemon), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, cloves, lavender, cardamom, ginger, honey, fennel, sage, cinnamon, sandalwood, jasmine, West Indian bittersweet tree, cocoa beans, liquorice; and traditionally used as the spice type and characteristic spice and spice bag of cigarette, cigar and pipe tobacco. Syrups such as high fructose corn syrup may also be suitable for use.

[0121] Flavoring agent can also comprise acidity or alkaline characteristics (for example organic acid, such as levulinic acid, succinic acid, pyruvic acid and benzoic acid).In some embodiments, if desired, flavoring agent can be combined with the element of substrate material.In the U.S. Patent No. 9,107,453 and U.S. Patent Application Publication No. 2012 / 0152265 of Dube et al., disclose suitable exemplary plant-derived composition, its disclosure is included in this paper in full by referring to.Can be used in combination with tobacco material to affect its sensory characteristics including organoleptic characteristics such as flavoring agent, shell etc. any material can be combined with substrate material.Specifically, organic acid can be incorporated into substrate material to affect the local flavor, sensation or the organoleptic characteristics of the medicine such as nicotine that can be combined with substrate material.For example, organic acid such as levulinic acid, lactic acid and pyruvic acid can be included in tobacco substrate together with nicotine, and the amount of these organic acids and any combination of nicotine equimolar (based on total organic acid content) organic acid are all suitable. For example, in some embodiments, the substrate material may include about 0.1 to about 0.5 moles of levulinic acid per mole of nicotine, about 0.1 to about 0.5 moles of pyruvic acid per mole of nicotine, about 0.1 to about 0.5 moles of lactic acid per mole of nicotine, or a combination thereof, until a concentration is reached where the total amount of organic acid present therein is equimolar to the total amount of nicotine present in the substrate material. Various other examples of organic acids that can be used to generate substrate materials are disclosed in U.S. Patent Application Publication No. 2015 / 0344456 to Dull et al., which is incorporated herein by reference in its entirety.

[0122] The selection of these additional components may be variable based on factors such as the desired organoleptic properties of the smoking article, and the disclosure is intended to encompass any such additional components apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See "Tobacco Flavoring Substances and Methods" (1972) by Gutcho of Noyes Data Corp. and "Tobacco Flavoring for Smoking Products" (1972) by Leffingwell et al., the disclosures of which are incorporated herein by reference in their entirety.

[0123] In some embodiments, the substrate material may include other materials having various inherent characteristics or properties. For example, the substrate material may include a plasticized material in the form of rayon or regenerated cellulose. As another example, viscose fibers (such as commercially available ) is suitable, the viscose fiber being a regenerated cellulose product incorporating silica. Some carbon fibers may include at least 95% or more carbon. Similarly, natural cellulose fibers such as cotton are suitable and may be impregnated with silica, carbon or metal particles or otherwise treated with silica, carbon or metal particles to enhance flame retardancy and minimize off-gassing, especially any undesirable off-gas components that adversely affect flavor (especially minimizing the possibility of any toxic off-gas products). Cotton may be treated with, for example, boric acid or various organic phosphate compounds to provide the desired flame retardant properties by dipping, spraying or other techniques known in the art. These fibers may also be treated with organic or metal nanoparticles (by coating, impregnation or both, such as dipping, spraying or vapor deposition) to impart the desired flame retardancy without undesirable off-gassing or melt-type performance.

[0124] In the depicted embodiment, the first layer and / or the second layer may also include an aerosol-forming material, such as an aerosol precursor composition. In some embodiments, the aerosol precursor composition may include one or more humectants, such as propylene glycol, glycerine and / or the like. In various embodiments, the amount of the aerosol precursor composition used in the aerosol delivery device can make the aerosol delivery device present acceptable sensory and sensory characteristics and desired performance characteristics. For example, in some embodiments, an aerosol precursor composition (such as, for example, glycerine and / or propylene glycol) can be used to produce a mainstream visible aerosol similar to tobacco smoke morphology in many respects. For example, the amount of the aerosol precursor composition incorporated into the substrate material of the smoking article can be in the range of about 4.5 grams or less, 3.5 grams or less, about 3 grams or less, about 2.5 grams or less, about 2 grams or less, about 1.5 grams or less, about 1 gram or less or about 5 grams. However, it should be noted that in other embodiments, values ​​outside these ranges are possible.

[0125] Representative types of other aerosol precursor compositions are described in U.S. Pat. No. 4,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jacob et al.; PCT WO 98 / 57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco (1988), a monograph by RJ Reynolds Tobacco Company; the disclosures of which are incorporated herein by reference. In some aspects, an aerosol source component can produce a visible aerosol when sufficient heat is applied thereto (and, if necessary, cooled with air), and the aerosol source component can produce a "smoke-like" aerosol. In other aspects, an aerosol source component can produce an aerosol that is substantially invisible but is identified as present by other characteristics such as flavor or mouthfeel. Thus, the properties of the generated aerosol may vary depending on the specific components of the aerosol delivery component.In various embodiments, the aerosol source component may be chemically simple relative to the chemical characteristics of the smoke generated by burning tobacco.

[0126] In some embodiments, an aerosol precursor composition, also referred to as a vapor precursor composition or "e-liquid," may include a variety of components, including, for example, a polyol (e.g., glycerol, propylene glycol, or a mixture thereof), nicotine, tobacco, tobacco extracts, and / or flavorants. Components and compositions of some possible types of aerosol precursors are described and characterized in U.S. Pat. No. 7,217,320 to Robinson et al., U.S. Pat. No. 2013 / 0008457 to Zheng et al., U.S. Pat. No. 2013 / 0213417 to Chong et al., U.S. Pat. No. 2014 / 0060554 to Collett et al., U.S. Pat. No. 2015 / 0030823 to Lipowicz et al., and U.S. Pat. No. 2015 / 0020830 to Koller, and WO 2014 / 182736 to Bowen et al., all of which are incorporated herein by reference. Other aerosol precursors that may be used include those contained in the following products: products; BLUTM products from Fontem Ventures BV; MISTIC MENTHOL products from MisticEcigs; MARK TEN products from Nu Mark LLC; JUUL products from Juul Labs; and VYPE products from CN Creative Ltd. Also possible are so-called “juices” for electronic cigarettes that are already available from Johnson Creek Enterprises LLC. Additional possible exemplary aerosol precursor compositions are sold under the following trade names: BLACK NOTE, COSMIC FOG, MILKMAN E-LIQUID, FIVE PAWNS, VAPOR CHEF, VAPE WILD, BOOSTED, THE STEAM FACTORY, MECH SAUCE, CASEY JONES MAINLINE RESERVE, DR. CRIMMY'S V-LIQUID, SMILEY E LIQUID, BEANTOWN VAPOR, CUTTWOOD, CYCLOPS VAPOR, SICBOY, GOOD LIFE VAPOR, TELEOS, PINUP VAPORS, SPACEJAM, MT. BAKER VAPOR, and JIMMY THE JUICE MAN.

[0127] The amount of aerosol precursor incorporated in the aerosol source member is such that the aerosol generating member provides acceptable sensory and desired performance characteristics. For example, it is desirable to use a sufficient amount of aerosol-forming material to generate a mainstream visible aerosol that is similar in many respects to the form of tobacco smoke. The amount of aerosol precursor in the aerosol generating system may depend on factors such as the number of puffs desired for each aerosol generating member. In one or more embodiments, an aerosol precursor composition of about 0.5 ml or more, about 1 ml or more, about 2 ml or more, about 5 ml or more, or about 10 ml or more may be included.

[0129] In the depicted embodiment, current changes in the spiral winding in the control body (i.e., the resonant transmitter), such as current changes directed by the control body (e.g., via a drive circuit) from a power source to the spiral winding, can generate an alternating electromagnetic field that penetrates the plurality of susceptor particles 260, 262 (i.e., the resonant receiver), thereby generating eddy currents within the plurality of susceptor particles 260, 262. The alternating electromagnetic field can be generated by directing an alternating current to the spiral winding. As described above, in some embodiments, the control component can include an inverter or inverter circuit configured to convert direct current provided by the power source into alternating current provided to the resonant transmitter.

[0130] The eddy currents flowing within the plurality of susceptor particles 260, 262 may generate heat by the Joule effect, wherein the amount of heat generated is proportional to the square of the current multiplied by the resistance of the material of the plurality of susceptor particles 260, 262. For embodiments in which the plurality of susceptor particles 260, 262 comprise a ferromagnetic material, heat may also be generated by hysteresis losses. Several factors contribute to the increase in temperature of the plurality of susceptor particles 260, 262, including, but not limited to, proximity to the helical winding, distribution of the magnetic field, resistivity of the material of the plurality of susceptor particles 260, 262, saturation flux density, skin effect or depth, hysteresis losses, magnetic susceptibility, magnetic permeability, and dipole moment of the material.

[0131] In this regard and as described above, both the plurality of susceptor particles 260, 262 and the spiral winding may include a conductive material. For example, the spiral winding and / or the plurality of susceptor particles 260, 262 may include a variety of conductive materials, including metals such as copper or aluminum, alloys of conductive materials (e.g., diamagnetic, paramagnetic, or ferromagnetic materials), or other materials such as ceramics or glasses in which one or more conductive materials are embedded. In some embodiments, the plurality of susceptor particles may be coated with a thermally conductive passivation layer (e.g., a thin layer of glass) or otherwise include a thermally conductive passivation layer.

[0132] In some embodiments, the plurality of porous susceptor particles 260, 262 contained in the aerosol source member may be supplemented by additional / alternative resonant receivers. For example, in some embodiments, the control body of the device may include a separate resonant receiver, such as, for example, one or more receiver pins.

Other examples include diammonium phosphate and / or other salts configured to help prevent the substrate material from being ignited, pyrolyzed, burned and / or scorched by a heat source. Various ways and methods of incorporating tobacco into smoking articles, particularly smoking articles designed not to intentionally burn substantially all of the tobacco in those smoking articles, are proposed in U.S. Patent Nos. 4,947,874 to Brooks et al.; 7,647,932 to Cantrell et al.; 8,079,371 to Robinson et al.; 7,290,549 to Banerjee et al.; and U.S. Patent Application Publication No. 2007 / 0215167 to Crooks et al.; the entire disclosures of the foregoing documents are incorporated herein by reference.

[0143] According to other embodiments of the present disclosure, the substrate material may also be combined with tobacco additive types traditionally used to make tobacco products. These additives may include the material type for enhancing the flavor and aroma of tobacco used to produce cigars, cigarettes, pipes, etc. For example, these additives may include various cigarette shells and / or dressing components. See, for example, U.S. Patent No. 3,419,015 to Wochnowski; U.S. Patent No. 4,054,145 to Berndt et al.; U.S. Patent No. 4,887,619 to Burcham et al.; U.S. Patent No. 5,022,416 to Watson; U.S. Patent No. 5,103,842 to Strang et al. and U.S. Patent No. 5,711,320 to Martin; Its disclosure is incorporated herein in its entirety by reference.

No. 4,830,028 to Lawson et al. and U.S. Pat. No. 8,186,360 to Marshall et al., the disclosure of which is incorporated herein by reference in its entirety.

[0144] Various types of flavorings or the material that changes the sensation or organoleptic properties of the mainstream aerosol of smoking articles or properties are suitable for use. In some embodiments, such flavorings can be provided from sources other than tobacco, and can be natural or artificial. For example, some flavorings can be applied to or incorporated into those regions of the generation aerosol of substrate material and / or smoking articles. In some embodiments, such preparations can be directly supplied to a heating chamber or region near a heat source, or provided with substrate material. Exemplary flavorings can include, for example, vanillin, ethyl vanillin, cheese, tea, coffee, fruit (for example, apple, cherry, strawberry, peach and citrus flavor, including lime and lemon), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, cloves, lavender, cardamom, ginger, honey, fennel, sage, cinnamon, sandalwood, jasmine, West Indian bittersweet tree, cocoa beans, liquorice; and traditionally used as the spice type and characteristic spice and spice bag of cigarette, cigar and pipe tobacco. Syrups such as high fructose corn syrup may also be suitable for use.

[0145] Flavoring agent can also comprise acidity or alkaline characteristics (for example organic acid, such as levulinic acid, succinic acid, pyruvic acid and benzoic acid).In some embodiments, if desired, flavoring agent can be combined with the element of substrate material.In the U.S. Patent No. 9,107,453 and U.S. Patent Application Publication No. 2012 / 0152265 of Dube et al., disclose suitable exemplary plant-derived composition, its disclosure is included in this paper in full by referring to.Can be used in combination with tobacco material to affect its sensory characteristics including organoleptic characteristics such as flavoring agent, shell etc. any material can be combined with substrate material.Specifically, organic acid can be incorporated into substrate material to affect the local flavor, sensation or the organoleptic characteristics of the medicine such as nicotine that can be combined with substrate material.For example, organic acid such as levulinic acid, lactic acid and pyruvic acid can be included in tobacco substrate together with nicotine, and the amount of these organic acids and any combination of nicotine equimolar (based on total organic acid content) organic acid are all suitable. For example, in some embodiments, the substrate material may include about 0.1 to about 0.5 moles of levulinic acid per mole of nicotine, about 0.1 to about 0.5 moles of pyruvic acid per mole of nicotine, about 0.1 to about 0.5 moles of lactic acid per mole of nicotine, or a combination thereof, until a concentration is reached where the total amount of organic acid present therein is equimolar to the total amount of nicotine present in the substrate material. Various other examples of organic acids that can be used to generate substrate materials are disclosed in U.S. Patent Application Publication No. 2015 / 0344456 to Dull et al., which is incorporated herein by reference in its entirety.

[0146] The selection of these additional components may be variable based on factors such as the desired organoleptic properties of the smoking article, and the disclosure is intended to encompass any such additional components apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See "Tobacco Flavoring Substances and Methods" (1972) by Gutcho of Noyes Data Corp. and "Tobacco Flavoring for Smoking Products" (1972) by Leffingwell et al., the disclosures of which are incorporated herein by reference in their entirety.

[0147] In some embodiments, the substrate material may include other materials having various inherent characteristics or properties. For example, the substrate material may include a plasticized material in the form of rayon or regenerated cellulose. As another example, viscose fibers (such as commercially available ) is suitable, the viscose fiber being a regenerated cellulose product incorporating silica. Some carbon fibers may include at least 95% or more carbon. Similarly, natural cellulose fibers such as cotton are suitable and may be impregnated with silica, carbon or metal particles or otherwise treated with silica, carbon or metal particles to enhance flame retardancy and minimize exhaust emissions, especially any undesirable exhaust components that adversely affect flavor (especially minimizing the possibility of any toxic exhaust products). Cotton may be treated with, for example, boric acid or various organic phosphate compounds to provide the desired flame retardant properties by dipping, spraying or other techniques known in the art. These fibers may also be treated with organic or metal nanoparticles (by coating, impregnation or both, such as dipping, spraying or vapor deposition) to impart the desired flame retardancy without undesirable exhaust emissions or melt-type performance.

[0148] In the depicted embodiment, the substrate material may also include an aerosol-forming material, such as an aerosol precursor composition. In some embodiments, the aerosol precursor composition may include one or more humectants, such as propylene glycol, glycerine and / or the like. In various embodiments, the amount of the aerosol precursor composition used in the aerosol delivery device can make the aerosol delivery device present acceptable sensory and sensory characteristics and desired performance characteristics. For example, in some embodiments, an aerosol precursor composition (such as, for example, glycerine and / or propylene glycol) can be used to produce a mainstream visible aerosol similar to tobacco smoke morphology in many respects. For example, the amount of the aerosol precursor composition incorporated into the substrate material of the smoking article can be in the range of about 4.5 grams or less, 3.5 grams or less, about 3 grams or less, about 2.5 grams or less, about 2 grams or less, about 1.5 grams or less, about 1 gram or less or about 5 grams. However, it should be noted that in other embodiments, values ​​outside these ranges are possible.

[0149] Representative types of other aerosol precursor compositions are described in U.S. Pat. No. 4,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jacob et al.; PCT WO 98 / 57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco (1988), a monograph by RJ Reynolds Tobacco Company; the disclosures of which are incorporated herein by reference. In some aspects, an aerosol source component can produce a visible aerosol when sufficient heat is applied thereto (and, if necessary, cooled with air), and the aerosol source component can produce a "smoke-like" aerosol. In other aspects, an aerosol source component can produce an aerosol that is substantially invisible but is identified as present by other characteristics such as flavor or mouthfeel. Thus, the properties of the generated aerosol may vary depending on the specific components of the aerosol delivery component.In various embodiments, the aerosol source component may be chemically simple relative to the chemical characteristics of the smoke generated by burning tobacco.

[0150] In some embodiments, an aerosol precursor composition, also referred to as a vapor precursor composition or "e-liquid," may include a variety of components, including, for example, a polyol (e.g., glycerol, propylene glycol, or a mixture thereof), nicotine, tobacco, tobacco extracts, and / or flavorants. Components and compositions of some possible types of aerosol precursors are described and characterized in U.S. Pat. No. 7,217,320 to Robinson et al., U.S. Pat. No. 2013 / 0008457 to Zheng et al., U.S. Pat. No. 2013 / 0213417 to Chong et al., U.S. Pat. No. 2014 / 0060554 to Collett et al., U.S. Pat. No. 2015 / 0030823 to Lipowicz et al., and U.S. Pat. No. 2015 / 0020830 to Koller, and WO 2014 / 182736 to Bowen et al., all of which are incorporated herein by reference. Other aerosol precursors that may be used include those contained in the following products: products; BLUTM products from Fontem Ventures BV; MISTIC MENTHOL products from MisticEcigs; MARK TEN products from Nu Mark LLC; JUUL products from Juul Labs; and VYPE products from CN Creative Ltd. Also possible are so-called “juices” for electronic cigarettes that are already available from Johnson Creek Enterprises LLC. Additional possible exemplary aerosol precursor compositions are sold under the following trade names: BLACK NOTE, COSMIC FOG, MILKMAN E-LIQUID, FIVE PAWNS, VAPOR CHEF, VAPE WILD, BOOSTED, THE STEAM FACTORY, MECH SAUCE, CASEY JONES MAINLINE RESERVE, DR. CRIMMY'S V-LIQUID, SMILEY E LIQUID, BEANTOWN VAPOR, CUTTWOOD, CYCLOPS VAPOR, SICBOY, GOOD LIFE VAPOR, TELEOS, PINUP VAPORS, SPACEJAM, MT. BAKER VAPOR, and JIMMY THE JUICE MAN.

[0151] The amount of aerosol precursor incorporated in the aerosol source member is such that the aerosol generating member provides acceptable sensory and desired performance characteristics. For example, it is desirable to use a sufficient amount of aerosol-forming material to generate a mainstream visible aerosol that is similar in many respects to the form of tobacco smoke. The amount of aerosol precursor in the aerosol generating system may depend on factors such as the number of puffs desired for each aerosol generating member. In one or more embodiments, an aerosol precursor composition of about 0.5 ml or more, about 1 ml or more, about 2 ml or more, about 5 ml or more, or about 10 ml or more may be included.

[0152] Return to reference Figure 6 and 7As described above, the substrate portion 310 includes a plurality of susceptor strips 370, each susceptor strip including a plurality of susceptor particles 360, wherein the susceptor particles 360 include resonant receptors. In various embodiments, the plurality of susceptor particles 360 may have various shapes, sizes, and materials, and in some embodiments, these different shapes, sizes, and materials may be combined in the same susceptor strip. For example, in some embodiments, one or more of the plurality of susceptor particles 360 may have a substantially spherical shape, a plate-like shape, a substantially cubic shape, an irregular shape (e.g., a shape having one or more (e.g., a plurality) of sides, the sides having different sizes), or any combination thereof. In various embodiments, the plurality of susceptor particles 360 may include ferromagnetic materials, including, but not limited to, cobalt, iron, nickel, zinc, manganese, and any combination thereof. In additional embodiments, the plurality of susceptor particles 360 may include other materials, including, for example, other porous metal materials such as aluminum or stainless steel, as well as ceramic materials such as silicon carbide, carbon materials, and any combination of any of the above. In yet another embodiment, the plurality of susceptor particles may include other conductive materials, including metals such as copper, alloys of conductive materials, or other materials in which one or more conductive materials are embedded.

[0153] In the depicted embodiment, current changes in the spiral winding in the control body (i.e., the resonant transmitter), such as current changes directed from the power source to the spiral winding by the control body (e.g., via a drive circuit), can generate an alternating electromagnetic field that penetrates the plurality of susceptor particles 360 (i.e., the resonant receiver), thereby generating eddy currents within the plurality of susceptor particles 360. The alternating electromagnetic field can be generated by directing an alternating current to the spiral winding. As described above, in some embodiments, the control component can include an inverter or inverter circuit configured to convert direct current provided by the power source into alternating current provided to the resonant transmitter.

[0154] The eddy currents flowing within the plurality of susceptor particles 360 may generate heat by the Joule effect, wherein the amount of heat generated is proportional to the square of the current multiplied by the resistance of the material of the plurality of susceptor particles 360. For embodiments in which the plurality of susceptor particles 360 comprise a ferromagnetic material, heat may also be generated by hysteresis losses. Several factors contribute to the increase in temperature of the plurality of susceptor particles 360, including, but not limited to, proximity to the helical winding, distribution of the magnetic field, resistivity of the material of the plurality of susceptor particles 360, saturation flux density, skin effect or depth, hysteresis losses, magnetic susceptibility, magnetic permeability, and dipole moment of the material.

[0155] In this regard and as described above, both the plurality of susceptor particles 360 and the spiral winding may include a conductive material. For example, the spiral winding and / or the plurality of susceptor particles 360 may include a variety of conductive materials, including metals such as copper or aluminum, alloys of conductive materials (e.g., diamagnetic, paramagnetic, or ferromagnetic materials), or other materials such as ceramics or glasses in which one or more conductive materials are embedded. In some embodiments, the plurality of susceptor particles may be coated with a thermally conductive passivation layer (e.g., a thin layer of glass) or otherwise include a thermally conductive passivation layer.

[0156] In some embodiments, the plurality of porous susceptor particles 360 included in the aerosol source member may be supplemented by additional / alternative resonant receivers. For example, in some embodiments, the control body of the device may include a separate resonant receiver, such as, for example, one or more receiver pins. Examples of suitable components are described in U.S. Patent Application Serial No. 15 / 799,365 filed on October 31, 2017, which is incorporated herein by reference in its entirety.

Various ways and methods of incorporating tobacco into smoking articles, particularly smoking articles designed not to intentionally burn substantially all of the tobacco in those smoking articles, are proposed in U.S. Patent Nos. 4,947,874 to Brooks et al.; 7,647,932 to Cantrell et al.; 8,079,371 to Robinson et al.; 7,290,549 to Banerjee et al.; and U.S. Patent Application Publication No. 2007 / 0215167 to Crooks et al.; the entire disclosures of the foregoing documents are incorporated herein by reference.

[0168] According to other embodiments of the present disclosure, the substrate material may also be combined with tobacco additive types traditionally used to make tobacco products. These additives may include the material type for enhancing the flavor and aroma of tobacco used to produce cigars, cigarettes, pipes, etc. For example, these additives may include various cigarette shells and / or dressing components. See, for example, U.S. Patent No. 3,419,015 to Wochnowski; U.S. Patent No. 4,054,145 to Berndt et al.; U.S. Patent No. 4,887,619 to Burcham et al.; U.S. Patent No. 5,022,416 to Watson; U.S. Patent No. 5,103,842 to Strang et al. and U.S. Patent No. 5,711,320 to Martin; Its disclosure is incorporated herein in its entirety by reference. Preferred shell materials may include water, sugar and syrup (e.g., sucrose, glucose and high fructose corn syrup), humectants (e.g., glycerol or propylene glycol) and flavorings (e.g., cocoa and licorice). Those added components may also include face covering materials (e.g., flavoring agents, such as menthol). See, for example, U.S. Pat. No. 4,449,541 to Mays et al., the disclosure of which is incorporated herein by reference in its entirety. Additional materials that may be added include those disclosed in U.S. Pat. No. 4,830,028 to Lawson et al. and U.S. Pat. No. 8,186,360 to Marshall et al., the disclosure of which is incorporated herein by reference in its entirety.

[0169] Various types of flavorings or the material that changes the sensation or organoleptic properties of the mainstream aerosol of smoking articles or properties are suitable for use. In some embodiments, such flavorings can be provided from sources other than tobacco, and can be natural or artificial. For example, some flavorings can be applied to or incorporated into those regions of the generation aerosol of substrate material and / or smoking articles. In some embodiments, such preparations can be directly supplied to a heating chamber or region near a heat source, or provided with substrate material. Exemplary flavorings can include, for example, vanillin, ethyl vanillin, cheese, tea, coffee, fruit (for example, apple, cherry, strawberry, peach and citrus flavor, including lime and lemon), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, cloves, lavender, cardamom, ginger, honey, fennel, sage, cinnamon, sandalwood, jasmine, West Indian bittersweet tree, cocoa beans, liquorice; and traditionally used as the spice type and characteristic spice and spice bag of cigarette, cigar and pipe tobacco. Syrups such as high fructose corn syrup may also be suitable for use.

[0170] Flavoring agent can also comprise acidity or alkaline characteristics (for example organic acid, such as levulinic acid, succinic acid, pyruvic acid and benzoic acid).In some embodiments, if desired, flavoring agent can be combined with the element of substrate material.In the U.S. Patent No. 9,107,453 and U.S. Patent Application Publication No. 2012 / 0152265 of Dube et al., disclose suitable exemplary plant-derived composition, its disclosure is included in this paper in full by referring to.Can be used in combination with tobacco material to affect its sensory characteristics including organoleptic characteristics such as flavoring agent, shell etc. any material can be combined with substrate material.Specifically, organic acid can be incorporated into substrate material to affect the local flavor, sensation or the organoleptic characteristics of the medicine such as nicotine that can be combined with substrate material.For example, organic acid such as levulinic acid, lactic acid and pyruvic acid can be included in tobacco substrate together with nicotine, and the amount of these organic acids and any combination of nicotine equimolar (based on total organic acid content) organic acid are all suitable. For example, in some embodiments, the substrate material may include about 0.1 to about 0.5 moles of levulinic acid per mole of nicotine, about 0.1 to about 0.5 moles of pyruvic acid per mole of nicotine, about 0.1 to about 0.5 moles of lactic acid per mole of nicotine, or a combination thereof, until a concentration is reached where the total amount of organic acid present therein is equimolar to the total amount of nicotine present in the substrate material. Various other examples of organic acids that can be used to generate substrate materials are disclosed in U.S. Patent Application Publication No. 2015 / 0344456 to Dull et al., which is incorporated herein by reference in its entirety.

[0171] The selection of these additional components may be variable based on factors such as the desired organoleptic properties of the smoking article, and the disclosure is intended to encompass any such additional components apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See "Tobacco Flavoring Substances and Methods" (1972) by Gutcho of Noyes Data Corp. and "Tobacco Flavoring for Smoking Products" (1972) by Leffingwell et al., the disclosures of which are incorporated herein by reference in their entirety.

[0172] In some embodiments, the substrate material may include other materials having various inherent characteristics or properties. For example, the substrate material may include a plasticized material in the form of rayon or regenerated cellulose. As another example, viscose fibers (such as commercially available ) is suitable, the viscose fiber being a regenerated cellulose product incorporating silica. Some carbon fibers may include at least 95% or more carbon. Similarly, natural cellulose fibers such as cotton are suitable and may be impregnated with silica, carbon or metal particles or otherwise treated with silica, carbon or metal particles to enhance flame retardancy and minimize exhaust emissions, especially any undesirable exhaust components that adversely affect flavor (especially minimizing the possibility of any toxic exhaust products). Cotton may be treated with, for example, boric acid or various organic phosphate compounds to provide the desired flame retardant properties by dipping, spraying or other techniques known in the art. These fibers may also be treated with organic or metal nanoparticles (by coating, impregnation or both, such as dipping, spraying or vapor deposition) to impart the desired flame retardancy without undesirable exhaust emissions or melt-type performance.

[0173] In the depicted embodiment, the substrate material may also include an aerosol-forming material, such as an aerosol precursor composition. In some embodiments, the aerosol precursor composition may include one or more humectants, such as propylene glycol, glycerine and / or the like. In various embodiments, the amount of the aerosol precursor composition used in the aerosol delivery device can make the aerosol delivery device present acceptable sensory and sensory characteristics and desired performance characteristics. For example, in some embodiments, an aerosol precursor composition (such as, for example, glycerine and / or propylene glycol) can be used to produce a mainstream visible aerosol similar to tobacco smoke morphology in many respects. For example, the amount of the aerosol precursor composition incorporated into the substrate material of the smoking article can be in the range of about 4.5 grams or less, 3.5 grams or less, about 3 grams or less, about 2.5 grams or less, about 2 grams or less, about 1.5 grams or less, about 1 gram or less or about 5 grams. However, it should be noted that in other embodiments, values ​​outside these ranges are possible.

[0174] Representative types of other aerosol precursor compositions are described in U.S. Pat. No. 4,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jacob et al.; PCT WO 98 / 57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco (1988), a monograph by RJ Reynolds Tobacco Company; the disclosures of which are incorporated herein by reference. In some aspects, an aerosol source component can produce a visible aerosol when sufficient heat is applied thereto (and, if necessary, cooled with air), and the aerosol source component can produce a "smoke-like" aerosol. In other aspects, an aerosol source component can produce an aerosol that is substantially invisible but is identified as present by other characteristics such as flavor or mouthfeel. Thus, the properties of the generated aerosol may vary depending on the specific components of the aerosol delivery component.In various embodiments, the aerosol source component may be chemically simple relative to the chemical characteristics of the smoke generated by burning tobacco.

[0175] In some embodiments, an aerosol precursor composition, also referred to as a vapor precursor composition or "e-liquid," may include a variety of components, including, for example, a polyol (e.g., glycerol, propylene glycol, or a mixture thereof), nicotine, tobacco, tobacco extracts, and / or flavorants. Components and compositions of some possible types of aerosol precursors are described and characterized in U.S. Pat. No. 7,217,320 to Robinson et al., U.S. Pat. No. 2013 / 0008457 to Zheng et al., U.S. Pat. No. 2013 / 0213417 to Chong et al., U.S. Pat. No. 2014 / 0060554 to Collett et al., U.S. Pat. No. 2015 / 0030823 to Lipowicz et al., and U.S. Pat. No. 2015 / 0020830 to Koller, and WO 2014 / 182736 to Bowen et al., all of which are incorporated herein by reference. Other aerosol precursors that may be used include those contained in the following products: products; BLUTM products from Fontem Ventures BV; MISTIC MENTHOL products from MisticEcigs; MARK TEN products from Nu Mark LLC; JUUL products from Juul Labs; and VYPE products from CN Creative Ltd. Also possible are so-called “juices” for electronic cigarettes that are already available from Johnson Creek Enterprises LLC. Additional possible exemplary aerosol precursor compositions are sold under the following trade names: BLACK NOTE, COSMIC FOG, MILKMAN E-LIQUID, FIVE PAWNS, VAPOR CHEF, VAPE WILD, BOOSTED, THE STEAM FACTORY, MECH SAUCE, CASEY JONES MAINLINE RESERVE, DR. CRIMMY'S V-LIQUID, SMILEY E LIQUID, BEANTOWN VAPOR, CUTTWOOD, CYCLOPS VAPOR, SICBOY, GOOD LIFE VAPOR, TELEOS, PINUP VAPORS, SPACEJAM, MT. BAKER VAPOR, and JIMMY THE JUICE MAN.

[0176] The amount of aerosol precursor incorporated in the aerosol source member is such that the aerosol generating member provides acceptable sensory and desired performance characteristics. For example, it is desirable to use a sufficient amount of aerosol-forming material to generate a mainstream visible aerosol that is similar in many respects to the form of tobacco smoke. The amount of aerosol precursor in the aerosol generating system may depend on factors such as the number of puffs desired for each aerosol generating member. In one or more embodiments, an aerosol precursor composition of about 0.5 ml or more, about 1 ml or more, about 2 ml or more, about 5 ml or more, or about 10 ml or more may be included.

[0178] In the depicted embodiment, current changes in the spiral windings in the control body (i.e., the resonant transmitter), such as current changes directed to the spiral windings by the control body (e.g., via a drive circuit) from a power source, generate local magnetic flux and hysteresis effects in the plurality of susceptor windings 472 (i.e., the resonant receivers), which subsequently provide local heating near the plurality of susceptor windings 472. As described above, in some embodiments, the control component may include an inverter or inverter circuit configured to convert direct current provided by the power source to alternating current provided to the resonant transmitter portion. For this topology, a three-circuit configuration may be used, wherein one circuit includes a half-bridge rectifier, another circuit includes a full-bridge rectifier, and a third circuit includes a transformer that can convert a DC signal to an AC signal.
