[0001] The present disclosure relates to aerosol delivery devices such as aerosol-generating smoking articles. The smoking article may be configured to heat or otherwise dispense an aerosol precursor or otherwise generate an aerosol from an aerosol precursor, which may contain a material made from or derived from tobacco or otherwise contain tobacco, which precursor may form an inhalable substance for human consumption. Background Art
[0002] Over the years, many smoking articles have been proposed as improvements or alternatives to smoking products based on burning tobacco. Some example alternatives include 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. Additional example alternatives use electrical energy to heat tobacco and / or other aerosol-generating substrate materials, such as described in U.S. Pat. No. 9,078,473 to Worm et al., which is incorporated herein by reference.

[0048] Tobacco materials that can be used in the present disclosure can change and can include, for example, flue-cured tobacco, burley tobacco, oriental tobacco or Maryland tobacco, dark tobacco, dark flue-cured tobacco and yellow flower (Rustica) tobacco, and other rare or special tobaccos or their mixtures.Tobacco materials can also include so-called "through mixing" form and processed form, such as processed tobacco stems (for example, cut-rolled or cut puffed stems), volume expanded tobacco (for example, puffed tobacco, such as dry ice expanded tobacco (DIET), preferably in the form of formula shredded tobacco (cut filler)), reconstructed tobacco (for example, reconstructed tobacco using papermaking type or cast sheet type process to manufacture). Various representative tobacco types, processed tobacco types, and tobacco blend types are described in U.S. Pat. No. 4,836,224 to Lawson et al., U.S. Pat. No. 4,924,888 to Perfetti et al., U.S. Pat. No. 5,056,537 to Brown et al., U.S. Pat. No. 5,159,942 to Brinkley et al., U.S. Pat. No. 5,220,930 to Gentry, U.S. Pat. No. 5,360,023 to Blakley et al., U.S. Pat. No. 6,701,936 to Shafer et al., U.S. Pat. No. 7,011,096 to Li et al., U.S. Pat. No. 7,017,585 to Li et al., and U.S. Pat. No. 7,025,066 to Lawson et al.; U.S. Patent Application Publication No. 2004 / 0255965 to Perfetti et al.; PCT Patent Application Publication No. WO 2004 / 0255965 to Bereman 02 / 37990; and Bombick et al., Basic and Applied Toxicology, 39, pp. 11-17 (1997), which are incorporated herein by reference. Further, exemplary tobacco compositions that may be useful in smoking devices (including smoking devices according to the present disclosure) are disclosed in Robinson et al., U.S. Pat. No. 7,726,320, which are incorporated herein by reference.
[0049] Further, the aerosol precursor composition may include an inert substrate having an inhalable substance or a precursor thereof integrated therein or otherwise deposited thereon. For example, a liquid including an inhalable substance may be coated on an inert substrate or adsorbed into an inert substrate so that when heat is applied, the inhalable substance is released in a form that can be drawn from the product of the present invention by applying positive or negative pressure. In some aspects, the aerosol precursor composition may include a mixture of spices and aromatic tobacco in the form of formulated tobacco shreds. On the other hand, the aerosol precursor composition may include a reconstituted tobacco material, such as described in U.S. Patent No. 4,807,809 of Pryor et al.; U.S. Patent No. 4,889,143 of Pryor et al.; and U.S. Patent No. 5,025,814 of Raker, the disclosures of which are incorporated herein by reference. For more information on suitable aerosol precursor compositions, see U.S. Patent Application Serial No. 15 / 916,834 filed by Sur et al. on March 9, 2018, which is incorporated herein by reference.
[0050] Regardless of the type of aerosol precursor composition, the aerosol delivery device may include an aerosol generating component configured to generate an aerosol from the aerosol precursor composition. For example, in the case of an electronic cigarette or a heat-not-burn device, the aerosol generating component may be or include a heating component. In the case of a heat-not-burn device, in some examples, the aerosol generating component may be or include at least one vibrating piezoelectric grid or piezomagnetic grid.
[0051] An example of a suitable heating assembly is an induction heater. Such a heater typically includes an induction transmitter and an induction receiver. The induction transmitter may include a coil configured to create an oscillating magnetic field (e.g., a magnetic field that varies periodically over time) when an alternating current is directed through the coil. The induction receiver may be at least partially positioned or received within the induction receiver and may include a conductive material (e.g., a ferromagnetic material or an aluminum-coated material). By directing an alternating current through the induction transmitter, eddy currents may be generated in the induction receiver via induction. The eddy currents flowing through the resistance of the material defining the induction receiver may heat it by Joule heating (i.e., by the Joule effect). The induction receiver that may define the atomizer may be wirelessly heated to form an aerosol from an aerosol precursor composition positioned close to the induction receiver. Various embodiments of an aerosol delivery device with an induction heater are described in U.S. Patent Application Publication No. 2017 / 0127722 to Davis et al.; U.S. Patent Application Publication No. 2017 / 0202266 to Sur et al.; U.S. Patent Application Serial No. 15 / 352,153 filed by Sur et al. on November 15, 2016; U.S. Patent Application Serial No. 15 / 799,365 filed by Sebastian et al. on October 31, 2017; and U.S. Patent Application Serial No. 15 / 836,086 to Sur, the entire contents of which are incorporated herein by reference.
[0052] In other embodiments, including those described in more detail herein, the heating assembly is a conductive heater such as in the case of a resistive heater. These heaters can be configured to generate heat when an electric current is directed through the heater. In various embodiments, the conductive heater can be provided in various forms, such as in the form of a foil, foam, disc, spiral, fiber, wire, film, yarn, strip, band or cylinder. Such heaters often include metallic materials and are configured to generate heat due to the resistance associated with passing an electric current through a resistor. Such resistive heaters can be positioned close to an aerosol precursor composition and heat the aerosol precursor composition to generate an aerosol. A variety of conductive materials that can be used with the present disclosure are described in the U.S. Patent Application Publication No. 2013 / 0255702 of Griffith et al. cited above.

In the example where the two are connected by a cable, the control body and the charger or other peripheral device may have the same or different types of connectors, wherein the cable has one type of connector or both types of connectors.
[0061] In examples involving inductively powered charging, the aerosol delivery device may be equipped with inductive wireless charging technology and include an inductive receiver to connect to a wireless charger, charging pad, etc. that includes an inductive transmitter and uses inductive wireless charging (including, for example, wireless charging according to the Qi wireless charging standard from the Wireless Power Consortium (WPC)).

[0065] As a further example, a component suitable for gesture recognition based on a specified movement of an aerosol delivery device can be used as an input device. See U.S. Patent Publication No. 2016 / 0158782 to Henry et al., which is incorporated herein by reference. As yet a further example, a capacitive sensor can be implemented on an aerosol delivery device to enable a user to provide input, such as by touching the surface of the device on which the capacitive sensor is implemented. In another example, a sensor capable of detecting motion associated with the device (e.g., an accelerometer, a gyroscope, a photoelectric proximity sensor, etc.) can be implemented on the aerosol delivery device to enable a user to provide input. Examples of suitable sensors are described in U.S. Patent Application Publication No. 2018 / 0132528 to Sur et al. and U.S. Patent Application Publication No. 2016 / 0158782 to Henry et al., which are incorporated herein by reference.

[0073] Figure 1 and Figure 2 An embodiment of an aerosol delivery device including a control body and a cartridge in the context of an electronic cigarette is shown. In this regard, Figure 1 and Figure 2 An aerosol delivery device 100 according to an example embodiment of the present disclosure is shown. As shown, the aerosol delivery device may include a control body 102 and a cartridge 104. The control body and the cartridge may be permanently or removably aligned in a functional relationship. In this regard, Figure 1 shows a stereoscopic view of an aerosol delivery device in a coupled configuration, and Figure 2 A partial cross-sectional view of the aerosol delivery device in a decoupled configuration is shown. In some embodiments, the aerosol delivery device can be substantially stick-shaped, substantially tubular-shaped, or substantially cylindrical-shaped, for example, when the control body and cartridge are in an assembled configuration.
[0074] The control body 102 and the cartridge 104 may be configured to engage with each other through a plurality of connections, such as a press-fit (or interference fit) connection, a threaded connection, a magnetic connection, etc. Therefore, the control body may include a first engagement component (e.g., a coupler) adapted to engage a second engagement component (e.g., a connector) on the cartridge. The first engagement component and the second engagement component may be reversible. As an example, either the first engagement component or the second engagement component may be a male thread, and the other may be a female thread. As a further example, either the first engagement component or the second engagement component may be a magnet, and the other may be a metal or a matching magnet. In a particular embodiment, the engagement component may be directly defined by existing components of the control body and the cartridge. For example, the housing of the control body may define a cavity at one end thereof, which is configured to receive at least a portion of the cartridge (e.g., a storage tank of the cartridge or other shell forming components of the cartridge). Specifically, the storage tank of the cartridge may be at least partially accommodated in the cavity of the control body, while the mouthpiece of the cartridge remains exposed outside the cavity of the control body. The cartridge can be retained within the cavity formed by the control body housing, such as by an interference fit (e.g., by using a stop and / or other features that create an interference engagement between an outer surface of the cartridge and an inner surface of a wall forming the control body cavity), by magnetic engagement (e.g., by using magnets and / or magnetic metal positioned within the cavity of the control body and positioned on the cartridge), or by other suitable techniques.
[0075] like Figure 2 As shown in the cross-sectional view shown, the control body 102 and the cartridge 104 may each include a plurality of corresponding components. Figure 2 The components shown in are representative of components that may be present in the control body and the cartridge and are not intended to limit the scope of components covered by the present disclosure. For example, as shown, the control body may be formed by a housing 206 (sometimes referred to as a control body shell), which may include a control component 208 (e.g., a processing circuit system, etc.), a flow sensor 210, a power source 212 (e.g., a battery, a supercapacitor), and an indicator 214 (e.g., an LED, a quantum dot-based LED), and the alignment of such components may be variable. The power source may be rechargeable, and the control body may include a charging circuit system coupled to the power source and configured to controllably charge the power source.
[0076] The cartridge 104 may be formed of a housing 216 (sometimes referred to as a cartridge shell) enclosing a reservoir 218, the reservoir 220 being configured to retain an aerosol precursor composition, and the housing 216 including a heating assembly 220 (aerosol generating component). In various configurations, the structure may be referred to as a tank; and accordingly, the terms "cartridge", "tank", etc. may be used interchangeably to refer to a shell or other housing that encloses a reservoir of an aerosol gas composition and includes a heater.
[0077] As shown, in some examples, the reservoir 218 can be in fluid communication with a liquid delivery assembly 220 that is adapted to wick or otherwise deliver an aerosol precursor composition stored in the reservoir housing to a heating assembly 228. In some examples, a valve can be positioned between the reservoir and the heating assembly, and the valve can be configured to control the amount of aerosol precursor composition that is transferred or delivered from the reservoir to the heating assembly.
[0078] Various examples of materials configured to generate heat when an electric current is applied therethrough may be used to form the heating assembly 220. The heating assembly in these examples may be a resistive heating assembly, such as a coil, a microheater, and the like. Example materials from which the heating assembly may be formed include Kanthal (FeCrAl), nichrome, nickel, stainless steel, indium tin oxide, tungsten, molybdenum disilicide (MoSi2), molybdenum silicide (MoSi), molybdenum disilicide doped with aluminum (Mo(Si,Al)2), titanium, platinum, silver, palladium, alloys of silver and palladium, graphite and graphite-based materials (e.g., carbon-based foams and yarns), conductive inks, boron-doped silicon dioxide, and ceramics (e.g., positive temperature coefficient ceramics or negative temperature coefficient ceramics). The heating assembly may be a resistive heating assembly or a heating assembly configured to generate heat by induction. The heating assembly may be coated with a thermally conductive ceramic such as aluminum nitride, silicon carbide, beryllium oxide, aluminum oxide, silicon nitride, or a composite thereof. Example embodiments of heating assemblies useful in aerosol delivery devices according to the present disclosure are described further below, and may be incorporated into devices such as those described herein.
[0079] There may be an opening 224 in the housing 216 (eg, at the mouthpiece end) to allow for the formed aerosol to be vented from the cartridge 104 .
[0080] The cartridge 104 may also include one or more electronic components 226, which may include integrated circuits, memory components (e.g., EEPROM, flash memory), sensors, etc. The electronic components may be suitable for communicating with the control component 208 and / or external devices by wired or wireless means. The electronic components may be located anywhere within the cartridge or its base 228.
[0081] Although the control component 208 and the flow sensor 210 are shown separately, it is understood that the various electronic components including the control component and the flow sensor can also be combined on a circuit board (e.g., PCB) that supports and electrically connects these electronic components. Further, the circuit board can be arranged relative to the central axis of the control body in a manner parallel to the length thereof. Figure 1. In some examples, the air flow sensor may include its own circuit board or other base assembly to which it may be attached. In some examples, a flexible circuit board may be utilized. The flexible circuit board may be configured in a variety of shapes, including a substantially tubular shape. In some examples, the flexible circuit board may be combined with, laminated to, or form part or all of a heater substrate.
[0082] The control body 102 and the cartridge 104 may include components adapted to facilitate fluid engagement therebetween. Figure 2 As shown, the control body may include a coupler 230 having a cavity 232 therein. The base 228 of the cartridge can be adapted to engage the coupler and may include a protrusion 234 adapted to the cavity. Such engagement can facilitate a stable connection between the control body and the cartridge, as well as establishing an electrical connection between the power supply 212 and the control component 208 in the control body and the heater 222 in the cartridge. Further, the housing 206 may include an air inlet 236, which may be a notch on the housing connected to the coupler, which allows air around the coupler to pass through and enter the housing, then pass through the cavity 232 of the coupler within the housing and enter the cartridge through the protrusion 234.
[0083] Useful couplers and mounts according to the present disclosure are described in U.S. Patent Application Publication No. 2014 / 0261495 to Novak et al., which is incorporated herein by reference. For example, Figure 2 The coupler 230 shown in the figure can define an outer periphery 238 configured to cooperate with the inner periphery 240 of the base 228. In one example, the inner periphery of the base can define a radius that is substantially equal to or slightly larger than the radius of the outer periphery of the coupler. Further, the coupler can define one or more protrusions 242 on the outer periphery, which are configured to engage with one or more grooves 244 defined at the inner periphery of the base. However, various other examples of structures, shapes and parts can also be used to couple the base to the coupler. In some examples, the connection between the base of the cartridge 104 and the coupler of the control body 102 can be substantially permanent, but in other examples, it can be a detachable connection so that, for example, the control body can be reused with one or more other cartridges that are disposable and / or refillable.
[0084] Figure 2As described above, the reservoir 218 shown in the figure can be a container or a fiber reservoir. For example, in this example, the reservoir may include one or more layers of non-woven fibers, which are substantially formed into the shape of a tube surrounding the interior of the housing 216. The aerosol precursor composition can be retained in the reservoir. For example, the liquid component can be retained by the reservoir adsorption. The reservoir can be connected to the liquid delivery component 222 fluid. In this example, the liquid delivery component can be transported to the heating component 220 in the form of a metal coil via capillary action or via a micropump. Therefore, the heating component and the liquid delivery component are in a heating arrangement.
[0085] In some examples, the microfluidic chip can be embedded in the reservoir 218, and the amount and / or mass of the aerosol precursor composition delivered from the reservoir can be controlled by a micropump such as based on microelectromechanical systems (MEMS) technology. Other example embodiments of reservoirs and delivery components useful in aerosol delivery devices according to the present disclosure are further described below, and such reservoirs and / or delivery components can be included in devices such as those described herein. Specifically, specific combinations of heating components and delivery components as further described herein can be incorporated into devices such as those described herein.
[0086] In use, when a user draws on the aerosol delivery device 100, air flow is detected by the flow sensor 210, and the heating assembly 220 is activated to vaporize the components of the aerosol precursor composition. Drawing on the mouthpiece end of the aerosol delivery device causes ambient air to enter the air inlet 236 and pass through the cavity 232 in the coupler 230 and the central opening in the protrusion 234 of the base 228. In the cartridge 104, the drawn air combines with the formed vapor to form an aerosol. The aerosol is agitated, sucked or otherwise drawn out of the heating assembly and discharged from the opening 224 in the mouthpiece end of the aerosol delivery device.
[0087] For further details on embodiments of an aerosol delivery device including a control body and a cartridge in the context of an electronic cigarette, see U.S. patent application serial number 15 / 836,086 to Sur cited above; and U.S. patent application serial number 15 / 916,834 to Sur et al.; and U.S. patent application serial number 15 / 916,696 filed by Sur on March 9, 2018, which are also incorporated herein by reference.
[0088] Figures 3 to 6 An embodiment of an aerosol delivery device including a control body and an aerosol source member in the context of a heat-not-burn device is shown. More specifically, Figure 3An aerosol delivery device 300 is shown according to an example embodiment of the present disclosure. The aerosol delivery device may include a control body 302 and an aerosol source component 304. In various embodiments, the aerosol source component and the control body may be permanently aligned or removably aligned in a functional relationship. In this regard, Figure 3 An aerosol delivery device is shown in a coupled configuration, and Figure 4 An aerosol delivery device is shown in a decoupled configuration.
[0089] like Figure 4 As shown, in various embodiments of the present disclosure, the aerosol source component 304 may include a heating end 406 and a mouthpiece end 408, wherein the heating end 406 is configured to be inserted into the control body 302, and the user draws on the mouthpiece end 408 to generate an aerosol. In various embodiments, at least a portion of the heating end may include an aerosol precursor composition 410.
[0090] In various embodiments, the aerosol source member 304 or a portion thereof may be wrapped in an outer wrapping material 412, which may be formed of any material that can be used to provide additional structure and / or support for the aerosol source member. In various embodiments, the outer wrapping material may include a material that resists heat transfer, which may include paper or other fiber materials, such as cellulose materials. The outer wrapping 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 water-insoluble particles. In addition, the filler material may be mixed with inorganic components. In various embodiments, the outer wrapper may be formed by multiple layers such as a block layer and a covering layer of the lower layer, such as a typical wrapper in a cigarette. Such materials may include, for example, lightweight "rag fibers", such as flax, sisal, straw and / or esparto. The outer wrapper may also include materials commonly used in filter components of conventional cigarettes, such as cellulose acetate. Further, the excess length of the coating at the mouthpiece end 408 of the aerosol source member can be used to simply separate the aerosol precursor composition 410 from the consumer's mouth, or to provide space for positioning filter materials as described below, or to affect the draw of the article or the flow characteristics of the vapor or aerosol leaving the device during puffing. Further discussion of the configuration of the coating material that can be used with the present disclosure can be found in U.S. Pat. No. 9,078,473 to Worm et al., cited above.
[0091] In various embodiments, other components may be present between the aerosol precursor composition 410 and the mouthpiece end 408 of the aerosol source component 304, wherein the mouthpiece end may include a filter 414, for example, the filter 414 may be made of cellulose acetate or polypropylene material. The filter may additionally or alternatively include multiple strands of tobacco-containing materials, such as described in U.S. Pat. No. 5,025,814 of Raker et al., which is incorporated herein by reference as a whole. In various embodiments, the filter may increase the structural integrity of the mouthpiece end of the aerosol source component, and / or provide filtering capacity (if necessary), and / or provide suction resistance. In some embodiments, one of the following components or any combination thereof may be positioned between the aerosol precursor composition and the mouthpiece end: an air gap; a phase change material for cooling air; a flavor release medium; an ion exchange fiber capable of selective chemical adsorption; aerogel particles as a filter medium; and other suitable materials.
[0092] Various embodiments of the present disclosure use one or more conductive heating components to heat the aerosol precursor composition 410 of the aerosol source member 304. In various embodiments, the heating component can be set in various forms, such as in the form of foil, foam, grid, hollow sphere, hemisphere, disc, spiral, fiber, wire, film, yarn, strip, belt or cylinder. Such heating components often include metal materials and are configured to generate heat due to the resistance associated with passing current through them. Such resistive heating components can be positioned to directly contact or approach the aerosol precursor composition of the aerosol source member, especially the aerosol source member. The heating component may be located in the control body and / or the aerosol source member. In various embodiments, the aerosol precursor composition may include a component (e.g., a heat conductive component) embedded in the matrix portion or otherwise as a part of the matrix portion, which can be used as a heating component or promote the function of the heating component. Some examples of various heating components and components are described in U.S. Patent No. 9,078,473 to Worm et al.
[0093] Some non-limiting examples of various heating component configurations include configurations in which the heating component is placed near the aerosol source component 304. For example, in some examples, at least a portion of the heating component may be surrounded by at least a portion of the aerosol source component. In other examples, when inserted in the control body 302, one or more heating components may be positioned adjacent to the exterior of the aerosol source component. In other examples, when the aerosol source component is inserted into the control body, at least a portion of the heating component may penetrate at least a portion of the aerosol source component (such as, for example, one or more tines and / or protrusions that penetrate the aerosol source component). In some cases, the aerosol precursor composition may include a structure in contact with the aerosol precursor composition, or a plurality of beads or particles embedded in the aerosol precursor composition or otherwise as part of the aerosol precursor composition, which may serve as a heating component or facilitate the function of the heating component.
[0094] Figure 5 shows a front view of an aerosol delivery device 300 according to an example embodiment of the present disclosure, and Figure 6 Shown through Figure 5 sectional view of the aerosol delivery device. Specifically, the control body 302 of the depicted embodiment may include a housing 516 including an opening 518 defined in an engagement end thereof, a flow sensor 520 (e.g., a puff sensor or a pressure switch), a control component 522 (e.g., a processing circuit system, etc.), a power source 524 (e.g., a battery, a supercapacitor), and an end cap including an indicator 526 (e.g., an LED). The power source may be rechargeable, and the control body may include a charging circuit system coupled to the power source and configured to controllably charge the power source.
[0095] In one embodiment, the indicator 526 may include one or more LEDs, quantum dot-based LEDs, etc. The indicator may be in communication with the control component 522 and illuminated, for example, when a user draws on the aerosol source member 304, as detected by the flow sensor 520 when coupled to the control body 302.
[0096] The control body 302 of the depicted embodiment includes one or more heating components 528 (individually or collectively referred to as heating components) configured to heat the aerosol precursor composition 410 of the aerosol source component 304. Although the heating components of various embodiments of the present disclosure may take a variety of forms, in some embodiments, the heating components 528 are preferably used in combination with the heating components 528 of the aerosol source component 304. Figure 5 and Figure 6In the particular embodiment depicted in , the heating assembly includes an outer barrel 530 and a heating assembly 532 (aerosol generating component), in which the heating assembly 532 includes a plurality of heater tines extending from a receiving base 534 (in various configurations, the heating assembly, or more specifically the heater tines, may be referred to as heaters). In the depicted embodiment, the outer barrel includes a double-walled vacuum tube constructed of stainless steel to retain the heat generated by the heater tines within the outer barrel, and more specifically, to retain the heat generated by the heater tines within the aerosol precursor composition. In various embodiments, the heater tines may be constructed of one or more conductive materials, including but not limited to copper, aluminum, platinum, gold, silver, iron, steel, brass, bronze, graphite, or any combination thereof.
[0097] As shown, the heating assembly 528 can extend proximate the engagement end of the housing 516 and can be configured to substantially surround the portion of the heating end 406 of the aerosol source member 304 that includes the aerosol precursor composition 410. In this manner, the heating assembly can define a generally tubular configuration. Figure 5 and Figure 6 As shown, a heating assembly 532 (e.g., a plurality of heater tines) is surrounded by an outer barrel 530 to create a receiving chamber 536. In this manner, in various embodiments, the outer barrel may include a non-conductive insulating material and / or configuration, including but not limited to insulating polymers (e.g., plastic or cellulose), glass, rubber, ceramic, porcelain, a double-walled vacuum structure, or any combination thereof.
[0098] In some embodiments, one or more parts or components of the heating assembly 528 can be combined, packaged and / or integrated with the aerosol precursor composition 410. For example, in some embodiments, the aerosol precursor composition can be formed of materials as described above and can include one or more conductive materials mixed therein. In some of these embodiments, the contacts can be directly connected to the aerosol precursor composition so that when the aerosol source member is inserted into the receiving chamber of the control body, the contacts are electrically connected to the electric energy source. Alternatively, the contacts can be integrated with the electric energy source and can extend into the receiving chamber so that when the aerosol source member is inserted into the receiving chamber of the control body, the contacts are electrically connected to the aerosol precursor composition. Because there is a conductive material in the aerosol precursor composition, the application of energy from the electric energy source to the aerosol precursor composition allows current to flow and thus generates heat from the conductive material. Therefore, in some embodiments, the heating assembly can be described as being integrated with the aerosol precursor composition. As a non-limiting example, graphite or other suitable conductive material may be mixed with, embedded in, or otherwise directly present on or in the material forming the aerosol precursor composition, thereby integrating the heating component with the medium.
[0099] As described above, in the illustrated embodiment, the outer barrel 530 can also be used to facilitate proper positioning of the aerosol source member 304 when the aerosol source member is inserted into the housing 516. In various embodiments, the outer barrel of the heating assembly 528 can engage the inner surface of the housing to provide alignment of the heating assembly relative to the housing. Thus, due to the fixed coupling between the heating assembly, the longitudinal axis of the heating assembly can extend substantially parallel to the longitudinal axis of the housing. In particular, the support barrel can extend from the opening 518 of the housing to the receiving base 534 to create a receiving chamber 536.
[0100] The size and shape of the heating end 406 of the aerosol source member 304 are designed for insertion into the control body 302. In various embodiments, the receiving chamber 536 of the control body can be characterized as being defined by a wall having an inner surface and an outer surface, the inner surface defining the internal volume of the receiving chamber. For example, in the depicted embodiment, the outer barrel 530 defines an inner surface that defines the internal volume of the receiving chamber. In the illustrated embodiment, the inner diameter of the outer barrel may be slightly larger than or approximately equal to the outer diameter of the corresponding aerosol source member (e.g., to produce a sliding fit), so that the outer barrel is configured to guide the aerosol source member to an appropriate position (e.g., a lateral position) relative to the control body. Therefore, the maximum outer diameter (or other dimension, depending on the specific cross-sectional shape of the embodiment) of the aerosol source member can be sized to be smaller than the inner diameter (or other dimension) at the inner surface of the wall of the open end of the receiving chamber in the control body. In some embodiments, the difference in the corresponding diameters may be small enough so that the aerosol source member fits tightly into the receiving chamber, and friction prevents the aerosol source member from moving without applying force. On the other hand, the difference is large enough to allow the aerosol source member to slide into or out of the receiving chamber without requiring undue force.
[0101] In the illustrated embodiment, the control body 302 is configured so that when the aerosol source member 304 is inserted into the control body, the heating assembly 532 (e.g., heater tines) is located at the approximate radial center of at least a portion of the aerosol precursor composition 410 at the heating end 406 of the aerosol source member. In this way, when used in conjunction with a solid or semi-solid aerosol precursor composition, the heater tines can be in direct contact with the aerosol precursor composition. In other embodiments, such as when used in conjunction with an extruded aerosol precursor composition defining a tube structure, the heater tines can be located inside a cavity defined by the inner surface of the extruded tube structure and will not contact the inner surface of the extruded tube structure.
[0102] During use, the consumer initiates the heating of the heating assembly 528, and in particular the heating assembly 532 adjacent to the aerosol precursor composition 410 (or a particular layer thereof). The heating of the aerosol precursor composition releases the inhalable substance in the aerosol source component 304 to produce the inhalable substance. When the consumer inhales on the mouthpiece end 408 of the aerosol source component, air is inhaled into the aerosol source component through an air inlet 538 such as an opening or hole on the control body 302. When the material sucked leaves the mouthpiece end of the aerosol source component, the combination of the sucked air and the released inhalable substance is inhaled by the consumer. In some embodiments, in order to initiate heating, the consumer can manually actuate a button or similar component, which causes the heating assembly of the heating assembly to receive electrical energy from a battery or other energy source. Electrical energy can be supplied for a predetermined length of time or can be manually controlled.
[0103] In some embodiments, the flow of electrical energy is not substantially carried out between puffs on the device 300 (although the energy flow may continue to maintain a baseline temperature above the ambient temperature, for example, to promote rapid heating to a temperature that activates the heating temperature). However, in the depicted embodiment, heating is initiated by the consumer's puff action using one or more sensors (such as flow sensors 520). Once the puff is interrupted, heating stops or decreases. When the consumer has taken a sufficient number of puffs, thereby releasing a sufficient amount of inhalable material (for example, an amount sufficient to be equivalent to a typical smoking experience), the aerosol source member 304 can be removed from the control body 302 and discarded. In some embodiments, further sensing components (such as capacitive sensing components and other sensors) as discussed in U.S. Patent Application No. 15 / 707,461 to Phillips et al. can be used, and the document is incorporated herein by reference.
[0104] In various embodiments, the aerosol source member 304 may be formed of any material suitable for forming and maintaining an appropriate configuration (such as a tubular shape) and suitable for retaining an aerosol precursor composition 410 therein. In some embodiments, the aerosol source member may be formed of a single wall, or in other embodiments, may be formed of multiple walls, and may be formed of a heat-resistant (natural or synthetic) material so as to retain its structural integrity (e.g., not degrade) at least at the temperature of the heating temperature provided by the electric heating assembly, as further discussed herein. Although in some embodiments, heat-resistant polymers may be used, in other embodiments, the aerosol source member may be formed of paper (such as paper that is roughly in the shape of a straw). As further discussed herein, the aerosol source member may have one or more layers associated therewith that act to substantially prevent the movement of steam passing therethrough. In an example embodiment, a layer of aluminum foil may be laminated to one surface of the aerosol source member. Ceramic materials may also be used. In further embodiments, insulating materials may be used so as not to unnecessarily remove heat from the aerosol precursor composition. Further example types of components and materials that can be used to provide the above-described functionality or as alternatives to the above-described materials and components can be those described in U.S. Patent Application Publication No. 2010 / 00186757 to Crooks et al. and U.S. Patent Application Publication No. 2011 / 0041861 to Sebastian et al., all of which are incorporated herein by reference.
[0105] In the depicted embodiment, the control body 302 includes a control component 522 that controls various functions of the aerosol delivery device 300, including providing power to the electric heating assembly 532. For example, the control component may include a processing circuit system (which may be connected to further components, as further described herein), which is connected to a power source 524 by a conductive cable (not shown). In various embodiments, the processing circuit system can control when and how the heating assembly 528, particularly the heater tines, receives electrical energy to heat the aerosol precursor composition 410 for releasing the inhalable substance for inhalation by the consumer. In some embodiments, such control can be activated by a flow sensor 520 as described in more detail above.
[0106] like Figure 5 and Figure 6As shown, the heating assembly 528 of the depicted embodiment includes an outer barrel 530 and a heating assembly 532 (e.g., a plurality of heater tines) extending from a receiving base 534. In some embodiments, such as those embodiments in which the aerosol precursor composition 410 includes a tube structure, the heater tines may be configured to extend into a cavity defined by an inner surface of the aerosol precursor composition. In other embodiments, such as the depicted embodiments in which the aerosol precursor composition includes a solid or semi-solid, when the aerosol source component is inserted into the control body 302, the plurality of heater tines are configured to penetrate the aerosol precursor composition contained in the heating end 406 of the aerosol source component 304. In such embodiments, one or more components of the heating assembly including the heater tines and / or the receiving base may be constructed of a non-stick or stick-resistant material (e.g., certain aluminum, copper, stainless steel, carbon steel, and ceramic materials). In other embodiments, one or more components of the heating assembly including the heater tines and / or the receiving base may include a non-stick coating, including, for example, a polytetrafluoroethylene (PTFE) coating (such as ), or other coatings, such as anti-stick enamel coatings, or ceramic coatings, such as or Thermolon TM .
[0107] Additionally, while in the depicted embodiment there are a plurality of heater tines 532 substantially equidistantly distributed about the receiving base 534, it should be noted that in other embodiments, any number of heater tines may be used, including as few as one heater tine, with any other suitable spatial configuration. Furthermore, in various embodiments, the length of the heater tines may vary. For example, in some embodiments, the heater tines may include a small protrusion, while in other embodiments, the heater tines may extend any portion of the length of the receiving chamber 536, including up to about 25%, up to about 50%, up to about 75%, and up to about the entire length of the receiving chamber. In yet other embodiments, the heating assembly 528 may take on other configurations. Based on the discussion provided above, examples of other heater configurations that may be suitable for use in the present invention may be found in U.S. Patent Nos. 5,060,671 to Counts et al., 5,093,894 to Deevi et al., 5,224,498 to Deevi et al., and 6,084,693 to Sprinkel et al. No. 5,228,460 to Jr. et al., No. 5,322,075 to Deevi et al., No. 5,353,813 to Deevi et al., No. 5,468,936 to Deevi et al., No. 5,498,850 to Das, No. 5,659,656 to Das, No. 5,498,855 to Deevi et al., No. 5,530,225 to Hajaligol, No. 5,665,262 to Hajaligol, and No. 5,573,692 to Das et al.; and No. 5,591,368 to Fleischhauer et al., which are incorporated herein by reference.
[0108] In various embodiments, the control body 302 may include an air inlet 538 (e.g., one or more openings or holes) therein for allowing ambient air to enter the interior of the receiving chamber 536. In this way, in some embodiments, the receiving base 534 may also include an air inlet. Thus, in some embodiments, when a consumer draws on the mouthpiece end of the aerosol source component 304, air can be drawn through the air inlet of the control body and the receiving base into the receiving chamber, transferred into the aerosol source component, and drawn through the aerosol precursor composition 410 of the aerosol source component for inhalation by the consumer. In some embodiments, the drawn air carries the inhalable substance through the optional filter 414 and leaves the opening at the mouthpiece end 408 of the aerosol source component. In the case where the heating assembly 532 is positioned inside the aerosol precursor composition, the heater tines can be activated to heat the aerosol precursor composition and release the inhalable substance through the aerosol source component.
[0109] As mentioned above Figure 5 and Figure 6 Described, specifically, various embodiments of the present disclosure use a conductive heater to heat the aerosol precursor composition 410. As also described above, various other embodiments use an induction heater to heat the aerosol precursor composition. In some of these embodiments, the heating component 528 may be configured as an induction heater including a transformer having an induction transmitter and an induction receiver. In an embodiment in which the heating component is configured as an induction heater, the outer cylinder 530 may be configured as an induction transmitter, and the heating component 532 (e.g., a plurality of heater tines) extending from the receiving base 534 may be configured as an induction receiver. In various embodiments, one or both of the induction transmitter and the induction receiver may be located in the control body 302 and / or the aerosol source component 304.
[0110] In various embodiments, the outer barrel 530 and the heating assembly 532 as the inductive transmitter and inductive receiver may be constructed of one or more conductive materials, and in further embodiments, the inductive receiver may be constructed of ferromagnetic materials, including but not limited to cobalt, iron, nickel, and combinations thereof. In one example embodiment, the foil material is constructed of a conductive material, and the heater tines are constructed of a ferromagnetic material. In various embodiments, the receiving base may be constructed of a non-conductive and / or insulating material.
[0111] The outer cylinder 530 as an inductive transmitter may include a laminate having a foil material around a support cylinder. In some embodiments, the foil material may include electrical traces printed thereon, such as, for example, in some embodiments, when the foil material is positioned around the heating assembly 532 as an inductive receiver, one or more electrical traces may form a spiral coil pattern. The foil material and the support cylinder may each define a tubular configuration. The support cylinder may be configured to support the foil material so that the foil material does not move into contact with the heater tines and thus short-circuit with the heater tines. In this way, the support cylinder may include a non-conductive material that is substantially transparent to the oscillating magnetic field generated by the foil material. In various embodiments, the foil material may be embedded in the support cylinder or otherwise coupled to the support cylinder. In the illustrated embodiment, the foil material engages with the outer surface of the support cylinder; however, in other embodiments, the foil material may be positioned at the inner surface of the support cylinder or completely embedded in the support cylinder.
[0112] The foil material of the outer barrel 530 can be configured to create an oscillating magnetic field (e.g., a magnetic field that changes periodically over time) when an alternating current is directed therethrough. The heater tines of the heating assembly 532 can be at least partially located or contained within the outer barrel and include a conductive material. By directing an alternating current through the foil material, eddy currents can be generated in the heater tines via induction. The eddy currents flowing through the resistance of the material defining the heater tines can heat it by Joule heating (i.e., by the Joule effect). The heater tines can be wirelessly heated to form an aerosol from an aerosol precursor composition 410 positioned proximate to the heater tines.
[0113] Other embodiments of aerosol delivery devices, control bodies, and aerosol source components are described in the above-referenced U.S. Patent Application Serial No. 15 / 916,834 to Sur et al.; U.S. Patent Application Serial No. 15 / 916,696 to Sur; and U.S. Patent Application Serial No. 15 / 836,086 to Sur.
[0114] Figure 7 and Figure 8 An embodiment of an aerosol delivery device including a control body and a cartridge in the case of a heat-not-burn device is shown. In this regard, Figure 7 700 including a control body 702 and a cartridge 704 according to various example implementations of the present disclosure. Specifically, Figure 7 A control body and a cartridge are shown coupled to each other. The control body and the cartridge may be removably aligned in a functional relationship.
[0115] Figure 8 More particularly shown is an aerosol delivery device 700 according to some example embodiments. As seen in the cross-sectional view shown therein, once again, the aerosol delivery device may include a control body 702 and a cartridge 704, each having a plurality of corresponding components. Figure 8The components shown in represent the components that may be present in the control body and the cartridge, and are not intended to limit the scope of the components covered by the present disclosure. For example, as shown in the figure, the control body may be formed by a control body housing or shell 806, and the control body housing or shell 806 may include a control component 808 (e.g., a processing circuit system, etc.), an input device 810, a power supply 812, and an indicator 814 (e.g., an LED, an LED based on quantum dots), and the alignment of such components is variable. Here, a specific example of a suitable control component includes a PIC16 (L) F1713 / 6 microcontroller of Microchip Technology Inc., which is described in Microchip Technology Inc., AN2265, Vibrating Mesh Nebulizer Reference Design (2016), which is incorporated herein by reference.
[0116] The cartridge 704 may be formed of a housing (sometimes referred to as a cartridge housing 816) that encloses a reservoir 818 configured to retain an aerosol precursor composition and includes a nozzle 820 having at least one piezoelectric grid / piezomagnetic grid (aerosol generating component). Similar to the above, in various configurations, the structure may be referred to as a tank, and accordingly, the terms "cartridge", "tank", etc. may be used interchangeably to refer to a housing or other housing that encloses a reservoir of an aerosol gas composition and includes a nozzle.
[0117] As mentioned above, Figure 8 The reservoir 818 shown can be a container or a fiber reservoir. The reservoir can be in fluid communication with a nozzle 820 to transfer the aerosol precursor composition stored in the reservoir housing to the nozzle. An opening 822 (e.g., at the mouthpiece end) can be present in the cartridge housing 816 to allow the formed aerosol to be discharged from the cartridge 704.
[0118] In some examples, the transmission assembly may be positioned between the reservoir 818 and the nozzle 820, and is configured to control the amount of aerosol precursor composition transferred or delivered to the nozzle from the reservoir. In some examples, the microfluidic chip may be embedded in the cartridge 704, and the amount and / or quality of the aerosol precursor composition delivered from the reservoir may be controlled by one or more microfluidic components. An example of a microfluidic component is a micropump 824, such as a micropump based on microelectromechanical systems (MEMS) technology. Examples of suitable micropumps include the MDP2205 type micropump and other micropumps from thinXXS Microtechnology AG, the mp5 and mp6 type micropumps and other micropumps from Bartels Mikrotechnik GmbH, and the piezoelectric micropump from TakasagoFluidic Systems (Takasago Electric).
[0119] Also as shown, in some examples, a microfilter 826 may be positioned between the micropump 824 and the nozzle 820 to filter the aerosol precursor composition delivered to the nozzle. Like the micropump, the microfilter is also a microfluidic component. Examples of suitable microfilters include flow-through microfilters, which are manufactured using a chip lab (LOC) technology.
[0120] In use, when the input device 810 detects a user input activating the aerosol delivery device, the piezoelectric / piezomagnetic grid is activated to vibrate, thereby drawing an aerosol precursor composition through the grid. This forms droplets of the aerosol precursor composition, which combine with air to form an aerosol. The aerosol is stirred, sucked or otherwise drawn from the grid and out of the opening 822 at the mouthpiece end of the aerosol delivery device.
[0121] The aerosol delivery device 700 may include an input device 810, such as a switch, sensor, or detector, for controlling the power supply to at least one piezoelectric / piezomagnetic grid of the nozzle 820 when aerosol generation is desired (e.g., when puffing during use). Thus, for example, a means or method is provided for turning off power to the grid when the aerosol delivery device is not being puffed during use, and for turning on power during puffing to actuate or trigger the generation of an aerosol and the dispensing of the aerosol from the nozzle. Additional representative types of sensing or detection mechanisms, their structures and configurations, their components, and general methods of operation thereof are described above and in U.S. Patent No. 5,261,424 to Sprinkel, Jr., U.S. Patent No. 5,372,148 to McCafferty et al., and PCT Patent Application Publication No. WO 2010 / 003480 to Flick, all of which are incorporated herein by reference.
[0122] For more information on the above and other embodiments of aerosol delivery devices without heat-not-burn devices, see U.S. patent application serial number 15 / 651,548 filed by Sur on July 17, 2017, which is incorporated herein by reference.
[0123] As described above, in the context of an electronic cigarette, a heat-not-burn device, or a no-heat-not-burn device, or even in the case of a device that includes the functionality of one or more of an electronic cigarette, a heat-not-burn device, or a no-heat-not-burn device, an example embodiment of an aerosol delivery device may include various electronic components. Fig. 9 A circuit diagram of an aerosol delivery device 900 is shown, which may be any one or more of the aerosol delivery devices 100, 300, 700 or may include the functionality of any one or more of the aerosol delivery devices 100, 300, 700 according to various example embodiments of the present disclosure.
[0124] like Fig. 9 As shown, the aerosol delivery device 900 includes a control body 902 having a control component 904 (having a processing circuit system 906) and a power supply 908, which components may correspond to or include the functions of the corresponding ones of the control body 102, 302, 702, the control component 208, 522, 808 and the power supply 212, 524, 812. The aerosol delivery device also includes an aerosol generating component 910, which may correspond to or include the functions of the piezoelectric grid / piezomagnetic grid of the heating component 222, 534 or the nozzle 820. In some embodiments, the aerosol delivery device, in particular the control body, includes a terminal 912, which is configured to connect the power supply 904 to the aerosol delivery device or in particular the control body. The control body may include an aerosol generating component or be configured to connect the aerosol generating component to a second terminal 914 of the control body.
[0125] In some examples, the aerosol delivery device 900 includes at least one sensor 916, including in some examples a first sensor 916a and / or one or more second sensors 916b, which are configured to generate a measurement of a property during use of the aerosol delivery device 900. In this regard, the first sensor may correspond to or include the functionality of the sensor 210, 520 or the input device 810. The first sensor can be a pressure sensor configured to generate a measurement of the pressure caused by the air flow through at least a portion of the aerosol delivery device, or otherwise receive input to indicate the use of the aerosol delivery device. The first sensor is configured to convert the measurement result / user input into a corresponding electrical signal, which may include analog-to-digital conversion. In some examples, the first sensor can be a digital sensor, a digital pressure sensor, etc., some suitable examples of which are manufactured by Murata Manufacturing Co., Ltd.
[0126] The processing circuit 906 may be configured to switchably connect the power supply 908 to a load 918 including an aerosol generating component 910, and thereby power the aerosol generating component. More specifically, for example, the processing circuit system may be configured to receive a corresponding electrical signal from the first sensor 916a, and in response connect the power supply to the load including the aerosol generating component, and thereby power the aerosol generating component. The processing circuit system may be configured to process the corresponding electrical signal to determine the on / off state, and may adjust the switching connection of the power supply in proportion to the measurement / user input generated by the first sensor. In some examples, the control component 904 further includes a high-side load switch (LS) 920 between the first sensor and the load and controllable by the processing circuit system to connect and disconnect the power supply to the load including the aerosol generating component.
[0127] As with the first sensor 916a, the second sensor(s) 916b are also configured to generate measurements of properties during use of the aerosol delivery device 900. These second sensors(s) may include any of a variety of different types of sensors. Examples of suitable sensors include current sensors, voltage sensors, resistance sensors, machine-readable information readers, position sensors, accelerometers, microphones, and the like. The machine-readable information reader is specifically configured to read machine-readable information such as according to any of many different automatic identification and data capture (AIDC) technologies (e.g., barcodes, radio frequency identification, etc.). The position sensor is configured to determine its geographic location in a variety of different ways (such as by interacting with a satellite navigation system such as a global positioning system (GPS)). In this regard, the geographic location may be given in the form of coordinates (e.g., latitude, longitude). In other examples, the geographic location may be given by an address or other identifier of a structure or land on the ground, or even further by a location within a structure or land on the ground. In a specific example, the geographic location may be given by the address of the user's workplace, or perhaps more specifically, by the location of a smoking room in the user's workplace.
[0128] Despite Fig. 9 Sensors are also shown separately in , but in some examples, the aerosol delivery device 900 also includes a camera system having a digital camera 922 and supporting electronics, which in some examples may include processing circuitry 906. The digital camera can be configured to capture images of objects or scenes in its field of view, and these images can be transmitted locally on the board of the aerosol delivery device or to an external computing device. The images can include still images or videos, or in some examples, the digital camera can be configured to selectively capture still images or capture video. For more information on suitable camera systems, see U.S. Patent No. 9,955,733 to Sur et al., which is incorporated herein by reference.
[0129] As described above, in some examples, control component 904 includes communication interface 924 to enable wireless communication with one or more networks, computing devices, or other appropriately enabled devices. In this regard, Fig.10A communication system 1000 is shown that includes an aerosol delivery device 900. The communication interface can be configured to be able to establish or connect to a computing device 1002 (external computing device) external to the aerosol delivery device. The computing device can also be embodied as a plurality of different devices, such as any one of a plurality of different mobile computers. More specific examples of suitable mobile computers include portable computers (e.g., laptop computers, notebooks, tablet computers), mobile phones (e.g., cell phones, smart phones), wearable computers (e.g., smart watches), and the like. In other examples, the computing device can be embodied as a computing device other than a mobile computer, such as in the form of a desktop computer, a server computer, and the like. In still other instances, the computing device can be embodied as another aerosol delivery device.
[0130] Additionally or alternatively, in some examples, the communication interface 924 of the aerosol delivery device 900 is configured to enable establishment of a wireless personal area network (WPAN) 1004 including the computing device 1002 or to enable connection to the WPAN 1004. Examples of suitable WPAN technologies include those based on or specified by the IEEE 802.15 standard, including Bluetooth, Bluetooth Low Energy (Bluetooth LE), ZigBee, infrared (e.g., IrDA), radio frequency identification (RFID), wireless USB, etc. In some examples, the processing circuit system 906 may then be configured to enable half-duplex Bluetooth low energy communication with the computing device via the wireless communication interface. Other examples of suitable WPAN technologies include Wi-Fi Direct and certain other technologies based on or specified by the IEEE 802.11 standard and supporting direct device-to-device communication.
[0131] In some examples, the communication interface 924 of the aerosol delivery device 900 may be configured to enable connection to a wireless local area network (WLAN) 1006. Examples of suitable WLAN technologies include those WLAN technologies based on or specified by the IEEE 802.11 standard and marketed as Wi-Fi. The WLAN includes appropriate networking hardware, some of which may be integrated, and others of which may be separate and interconnected. As shown, for example, the WLAN includes a wireless access point 1008 configured to allow wireless devices including the aerosol delivery device 900 and the computing device 1002 to connect to the WLAN. Also as shown, for example, the WLAN may include a gateway device 1010 (such as a residential gateway) configured to connect the WLAN to an external computer network 1012 (such as a wide area network (WAN) such as the Internet) such as the Internet. In some examples, the wireless access point or gateway device may include an integrated router to which other systems or devices may be connected. A WLAN may also include other integrated or separate and connected networking hardware such as network switches, hubs, digital subscriber line (DSL) modems, cable modems, and the like.
[0132] In some examples, the system 1000 may further include a service platform 1014, which may be embodied as a computer system accessible by the WLAN 1006 or the external network 1012 (as shown). The service platform may include one or more servers, such as may be provided by one or more blade servers, cloud computing infrastructure, distributed databases, etc. In some examples, the service platform is embodied as a distributed computing device including multiple computing devices, such as may be used to provide a cloud computing infrastructure or a distributed database. An example of a suitable distributed database is a blockchain, which is a shared, immutable ledger for recording transactions. And in these examples, the computing devices forming the service platform may communicate with each other via a network such as an external network.
[0133] In some examples, the service platform 1014 can be accessed by the aerosol delivery device 900 via the WLAN 1006 and the external network 1012, and is configured to provide one or more services to users of the aerosol delivery device and possibly users of other aerosol delivery devices. For example, the service platform can be operated by a retailer of an aerosol delivery device or aerosol delivery device component, an aerosol precursor composition, etc. The service platform can enable users to order or reorder aerosol precursor compositions, access and use various features, such as for monitoring, tracking or communicating machine learning models, user profiles, or information derived from machine learning models, user profiles, etc. (described in more detail below). In this regard, the service platform can store machine learning models and / or user profiles, and enable users to transfer one or both of machine learning models or user profiles between different aerosol delivery devices. Alternatively, an aerosol delivery device can be capable of device-to-device transmission from one aerosol delivery device to another aerosol delivery device (e.g., a computing device 1002 embodied as an aerosol delivery device).
[0134] In some examples, similar to aerosol delivery device 900, although the WLAN or external network may be different between the aerosol delivery device and the computing device, the service platform 1014 may also be accessed by the computing device 1002 via WLAN 1006 and the external network 1012. The computing device may include or otherwise provide an installed application or other interface through which the service platform can be accessed. The application or other interface may be or may be provided by a thin client and / or other client application, such as a web browser application through which a web page (e.g., a service portal) provided by the service platform can be accessed. As another example, the application or other interface may be or may be provided by a dedicated application, such as a mobile application installed on a computing device embodied as a mobile computing device.
[0135] Back to Fig. 9 And further reference Fig.10 , in examples where the aerosol delivery device 900 includes a camera system having a digital camera 922, the digital camera may be configured to capture an image of the face of an attempted user of the aerosol delivery device (a facial image). In these examples, the processing circuit system 906 may be configured to perform facial recognition using the facial image to verify that the attempted user is an authorized user of the aerosol delivery device. The processing circuit system may be configured to subsequently control at least one functional element of the aerosol delivery device based on the verification of the attempted user. This may include a processing circuit system that is configured to change a locked state of the aerosol delivery device based on the verification of the attempted user.
[0136] The aerosol delivery device 900 may be configured to communicate with the service platform 1014 to perform facial recognition, or the aerosol delivery device may perform facial recognition locally without the service platform. In the latter example, the processing circuit system 906 may be configured to perform nodal analysis (sometimes referred to as node analysis), in which analysis calculations of facial images are performed locally at the aerosol delivery device. Therefore, facial recognition can be performed using quickly completed calculations and contours stored in onboard memory without storing facial images. Nodal analysis consumes less computing power and enables facial recognition with reduced latency. Nodal analysis can also enhance security and use less power on the aerosol delivery device.
[0137] In some examples, processing circuit system 906 may be configured to perform node analysis in response to a visual event, such as an attempting user appearing in the field of view of digital camera 922. In response, the digital camera may capture an image of the attempting user's face, and processing circuit system 906 may be configured to perform facial recognition locally using the image to verify that the attempting user is an authorized user of the aerosol delivery device without accessing service platform 1014.
[0138] The processing circuit system 906 can perform facial recognition in any of a number of different ways. In some examples, the processing circuit system can be trained to recognize the face of the authorized user using one or more reference images of the authorized user, which can define a training set for facial recognition. The training can result in at least a threshold accuracy when verifying the authorized user, and can be performed before the facial recognition is used to control (multiple) functional elements of the aerosol delivery device 900 (such as the lock state of the aerosol delivery device). In some further examples, initial training can be performed to at least achieve a threshold accuracy, and then the initial training can be continued as facial recognition is performed, adding verified images of authorized users to the training set for facial recognition.
[0139] In some examples, the facial image may be divided into a plurality of points (e.g., 100 points) that may be used to verify that the attempting user is an authorized user. Processing circuit system 906 may also include object recognition logic to distinguish an image of a face from an image of another object. This may help localize the process and reduce delays or computational errors relative to techniques that involve performing at least some of the analysis remote from aerosol delivery device 900.
[0140] The digital camera 922 may be or include a linear imager to capture facial images, or the digital camera may be or include a logarithmic imager. In addition to being less dependent on brightness changes that may occur due to shadows, reflections, etc., logarithmic imagers may provide a higher dynamic range for image processing than linear imagers. This may improve image capture, which in turn may improve analysis of the image.
[0141] Linear imagers typically use pixels that generate a voltage as a linear function of light which results in limited contrast. Contrast in linear imagers may also depend on brightness which may introduce reflection based contrast issues. Logarithmic imagers may reduce if not eliminate these issues. In a logarithmic imager, the pixel generates a voltage that is a logarithmic function of light which can improve contrast. Logarithmic imagers also offer a wider range of light levels, thus increasing contrast due to the logarithmic generation of the pixel voltage. Logarithmic imagers can be more beneficial than linear imagers in locations where shadows are generated or there is cloud cover. Logarithmic imagers can also be beneficial when excessive reflections are produced on a person due to sudden flashes of headlights or lamps.
[0142] In addition to or in lieu of facial recognition, the aerosol delivery device 900 may be equipped with other machine learning capabilities. According to some example implementations, the processing circuit system 906 may be configured to record data for multiple uses of the aerosol delivery device. For each use, the data may include measurements of properties from sensors 916 (including first sensor 916a and / or (multiple) second sensors 916b). The processing circuit system may then be configured to establish a machine learning model to predict a target variable, and deploy the machine learning model to predict the target variable, and control at least one functional element of the aerosol delivery device based thereon. In this regard, a machine learning model may be constructed using a machine learning algorithm, at least one feature selected from the property, and a training set generated from the measurement of the property.
[0143] In some examples, the multiple uses of the aerosol delivery device 900 may include corresponding user puffs, wherein each puff causes an airflow to flow through at least a portion of the housing of the aerosol delivery device and is used for the user to inhale the aerosol. In some of these examples, the processing circuit system 906 may be configured to have measurements of properties from the sensor 916 of the time and duration of each user puff. In some examples, the time and duration may be provided, or determined according to a real-time clock (RTC) in the processing circuit system, or accessed by the processing circuit system.
[0144] The target variable may be any of a number of different variables for different applications or use cases. The target variable may be a measure of user health, based on a measure of activity, and further based on a usage rate that depends on the time and duration of puffs by individual users. In some examples, the target variable may be or include a user profile that depends on at least one of an attribute and the time and duration of puffs by individual users.
[0145] In some examples, the user profile may include information indicating a predicted period of non-use of the aerosol delivery device 900. In some of these examples, control of the functional element(s) of the aerosol delivery device may include a processing circuit system 906 configured to cause the aerosol delivery device to enter a sleep mode during the predicted period of non-use. The sleep mode may be a low power or power saving mode in which power to components that may not be needed during the non-use period, such as the first sensor 916a, may be cut off. In some examples, the mode may include a power supply component that may be used in charging the power supply 908 of the aerosol delivery device, which may be particularly useful in the case where the power supply can be charged from an RF-based charger.
[0146] As indicated above and described in more detail below, the user profile may depend on the suction of each user. In this regard, the user profile may include or otherwise define the suction profile of the user. The suction profile may describe the suction of each user. The suction profile may include the time and duration of the corresponding user's suction. Additionally or alternatively, the suction profile may include any of the attributes that are characteristics of the suction of each user or otherwise related to the suction of each user. As described below, for example, this may include the measurement of the pressure proportional to the suction intensity of each user, the measurement of the pressure proportional to the total specific material (TPM) in the aerosol generated during the suction of each user, the power dissipated by the aerosol generating component during each suction, the aerosol precursor composition used during the suction of each user, the geographical location of the aerosol delivery device during each suction, etc. For other examples of the attributes that can be incorporated into the jet profile, see the British patent application serial number 1818007.5 filed on November 5, 2018, which is incorporated herein by reference.
[0147] In some examples, the one or more properties on which the user profile depends may include a measurement of pressure from the first sensor 916a that is proportional to the intensity of the respective user's puff. In other examples, the one or more properties on which the user profile depends may include a pressure measurement that is proportional to the TPM in the aerosol produced during the respective user's puff.
[0148] In some further examples where the target variable is or includes a user profile, control of the functional element(s) may include a processing circuit system configured to control power from a power source 908 to a load 918 including an aerosol generating component 910 based on the user profile.
[0149] In yet further examples, the aerosol generating component 910 includes a plurality of grids surrounded by a piezoelectric or piezomagnetic material (e.g., the piezoelectric grid / piezomagnetic grid of the nozzle 820). In some of these examples, the processing circuit system 906 can be configured to selectively drive the piezoelectric or piezomagnetic material to vibrate and discharge the components of the aerosol precursor composition through one or more of the grids. In this regard, the processing circuit system can be configured to control power from the power supply 908 to selectively drive the piezoelectric or piezomagnetic material based on a user profile.
[0150] In a specific example, the aerosol generating component 910 includes three grids operable to vibrate at 113 kilohertz (kHz), 800kHz, and 2.2 megahertz, respectively, wherein the higher the frequency, the smaller the droplets of the aerosol precursor composition formed. If the user frequently uses the aerosol delivery device 900, the processing circuit system 906 can drive all three grids. If the user uses the aerosol delivery device less frequently, less than three grids can be driven. At the low end, a 113kHz grid can be driven, which can form droplets larger than the other two grids. In some users, larger droplets may not be fully ingested, which can help users reduce the use of the device.
[0151] In some examples where the second sensor(s) 916b include a current or voltage sensor, the current or voltage sensor may be configured to generate a measurement of the current through the aerosol generating component 910 or a measurement of the voltage across the aerosol generating component 910. In some of these examples, the processing circuit system 906 may be further configured to determine the power dissipated by the aerosol generating component during each user's puff based on the measurement of the current through the aerosol generating component 910 or the measurement of the voltage across the aerosol generating component 910. Also in some of these examples, the one or more attributes on which the user profile depends may include the power dissipated by the aerosol generating component during each user's puff.
[0152] In some examples, the aerosol delivery device 900 can be used with at least a plurality of aerosol precursor compositions, and the second sensor(s) 916b can include a reader configured to read machine-readable information. Based on the machine-readable information, the processing circuit system 906 can be configured to identify a corresponding aerosol precursor composition in the plurality of aerosol precursor compositions during each user puff when used with the aerosol delivery device.
[0153] A plurality of aerosol precursor compositions may have different resistivities, which may also be used to identify individual aerosol precursor compositions in the plurality of aerosol precursor compositions. In some examples where the second sensor(s) 916b include a resistance sensor, the resistance sensor may be a sensor configured to produce a measurement of the resistance of the aerosol precursor composition. Subsequently, based on the measurement of the resistance, the processing circuit system may be configured to determine the resistivity of the aerosol precursor composition, and then identify the aerosol precursor composition based on its resistivity.
[0154] In some of the above examples, the user profile may depend on at least a corresponding aerosol precursor composition in a plurality of aerosol precursor compositions identified by the processing circuit system 906, and the time and duration of each user's puff when used with an aerosol delivery device. In some further examples, the aerosol generating component 910 may be a plurality of aerosol generating components configured to generate aerosols from a plurality of aerosol precursor compositions. In some of these examples, the control of the (multiple) functional elements may include a processing circuit system that is configured to automatically select among the plurality of aerosol generating components at different times based on the user profile.
[0155] In other further examples, processing circuit system 906 may be further configured to predict depletion of a particular one of the plurality of aerosol precursor compositions based on a user profile. In some of these examples, control of the functional element(s) may include processing circuit system 906 configured to communicate with computing device 1002 or service platform 1014 via communication interface 924 (e.g., a wireless communication interface) to order additional amounts of a particular one of the plurality of aerosol precursor compositions.
[0156] To further illustrate some of the above examples, consider the case of four aerosol precursor compositions of different flavoring agents (with different flavoring agents): Menthol, Crema, Chai, and Tropicana. The user profile may include measurements of the time and duration of use of different flavoring agents. The processing circuit system may apply regression principles to the measurements over a period of time (e.g., 30 days) and determine boundary conditions. Or in some examples, the processing circuit system may upload the measurements to the service platform 1014, which may determine the boundary conditions.
[0157]
[0158] Based on boundary conditions, it can be understood that users prefer menthol and tea, and this understanding can be used to deliver or otherwise provide more of these flavors to users. The service platform 1014 can be accessed by the marketing team in particular to supply more of those flavors that are used more frequently by the user (or more than more users).
[0159] In some examples, the processing circuit system 906 may be configured to communicate the target variable to the service platform 1014 via the wireless communication interface 924, and the service platform 1014 is configured to electronically record the target variable on the blockchain. Those who have access to the blockchain can therefore access the target variable. The predicted target variable can be compared with the actual data of the target variable. As the prediction and the actual converge, the system 1000 can predict the actual data and thus use machine learning and blockchain to improve the efficiency of the system.
[0160] In some examples where the second sensor(s) 916b include a location sensor configured to determine a geographic location of an aerosol delivery device, one or more attributes on which the user profile depends may include the geographic location of the aerosol delivery device during each user puff. In other examples, the computing device 1002 may include a location sensor configured to determine a geographic location of the computing device (in addition to or in lieu of the aerosol delivery device). When the aerosol delivery device is close to the computing device, the geographic location of the computing device may approximate the geographic location of the aerosol delivery device. The computing device may communicate the geographic location to the aerosol delivery device via a communication interface 924 (e.g., a wireless communication interface) for use similar to the geographic location determined by the location sensor of the aerosol delivery device.
[0161] As a further example, a user profile may include information indicating one or more predicted geographic areas of use or non-use of the aerosol delivery device, the predicted geographic areas being predicted based on the geographic location of the aerosol delivery device 900 (or a computing device 1002 near the aerosol delivery device). In some of these examples, control of the (multiple) functional elements of the aerosol delivery device may include a processing circuit system 906 that is configured to unlock the aerosol delivery device when the aerosol delivery device is within the predicted geographic area of use, or to lock the aerosol delivery device when the aerosol delivery device is outside the (multiple) predicted geographic areas of use or within the predicted geographic areas of non-use. In this regard, the aerosol delivery device may learn where an authorized user uses or does not use the device, and lock or unlock the device based on that information, which may prevent unauthorized use, such as in the case of a lost or stolen aerosol delivery device.
[0162] In other examples of the above examples involving (multiple) predicted geographic areas of use or non-use, control of (multiple) functional elements of the aerosol delivery device 900 may include a processing circuit system 906, which is configured to prepare the aerosol delivery device for use when approaching or within the predicted geographic area of use. This may include resuming the aerosol delivery device from a sleep mode or otherwise activating a component (such as the first sensor 916a) that may have been powered off. Additionally or alternatively, in examples in which the aerosol generating component 910 is or includes a heating component, the processing circuit system may initiate pre-heating of the heating component. Conversely, the processing circuit system may be configured to cause the aerosol delivery device to enter a sleep mode when the aerosol delivery device exits the (multiple) predicted geographic areas of use or is located outside the (multiple) predicted geographic areas of use, or is approaching or within the predicted geographic area of non-use.
[0163] In some further examples, the user profile may include information indicating one or more predicted geographic areas of modified use of the aerosol delivery device, the information being predicted based on the geographic location of the aerosol delivery device 900 (or a computing device 1002 near the aerosol delivery device). In some of these examples, control of the functional element(s) may include a processing circuit system 906 configured to cause the aerosol delivery device to adjust the volume of aerosol generated by the aerosol delivery device when the aerosol delivery device is located within the predicted geographic area of modified use. Specifically, for example, the aerosol delivery device may reduce the volume of aerosol generated by the aerosol delivery device when the aerosol delivery device is indoors or in another geographic area where modified use is desired.
[0164] Similar to the predicted geographic area of use (or modified use), other aspects of the user profile can be used to lock the aerosol delivery device 900 for authorized users. As described above, the user profile may include or otherwise define the profile of the authorized user, and the profile of the authorized user may describe the individual user suctions of the user. In some examples, the aerosol delivery device may lock the suction profile for the authorized user. In these examples, the processing circuit system 906 may develop the suction profile specific to use of each suction during the use of the aerosol delivery device, and compare the suction profile specific to use with the suction profile in the user profile. The processing circuit system may enable continued use when the suction profile specific to use matches or otherwise has at least a threshold similarity with the suction profile, and lock the aerosol delivery device to prevent continued use when the suction profile specific to use does not match or otherwise has at least a threshold similarity with the suction profile.
[0165] In another similar example, processing circuitry 906 may use a puff profile to distinguish between users who are over or under an allowed age for use of aerosol delivery device 900. Here, processing circuitry may enable continued use when the use-specific puff profile indicates that the user is at least the allowed age, and lock the aerosol delivery device from continued use when the use-specific puff profile indicates that the user is at least the allowed age.
[0166] In some examples, the aerosol delivery device 900 is configured to communicate with a second aerosol delivery device (e.g., a computing device 1002 embodied as an aerosol delivery device) via a communication interface 924 (e.g., a wireless communication interface). In some of these examples, the aerosol delivery device may be configured to receive from the second aerosol delivery device a second measurement of the attribute during use of the second aerosol delivery device, the use of the second aerosol delivery device including puffs by individual second users, and second times and durations for puffs by individual second users. The processing circuit system 906 may be further configured to establish and deploy a second machine learning model to predict a second target variable. The second machine learning model may be constructed using a machine learning algorithm, at least one feature selected from the attribute, and a second training set generated from a second measurement of the attribute. Here, the second target variable may be a second user profile that depends on at least one of the attribute and the second time and duration for puffs by individual second users.
[0167] In the above example, a user can pair his aerosol delivery device 900 with another user's aerosol delivery device. This can allow the user to monitor the user and other users' usage, such as time, frequency, aerosol precursor composition, etc., which can create a social network in a sense. There can also be more than two aerosol delivery devices to provide a larger social network, where each user can monitor the usage of users of the devices in the social network. In these or other examples, the aerosol delivery device can additionally or alternatively upload usage information to the service platform 1024. For more information on suitable social network features, see U.S. Patent Application Publication No. 2015 / 0224268 to Henry et al., which is incorporated herein by reference.
[0168] In some examples where the second sensor(s) 916b include an accelerometer, the accelerometer may be configured to generate a measurement of the acceleration of the aerosol delivery device 900, and the target variable may be a logical activity of a user of the aerosol delivery device. In some of these examples, the machine learning model may be or include an activity detection model to predict the logical activity of the user. And the processing circuit system 906 may be configured to construct the activity detection model using the machine learning algorithm, at least one feature including acceleration, and a training set generated from the measurement of acceleration.
[0169] In other examples where the second sensor(s) 916b include an accelerometer, the target variable may be a logical carry position of the aerosol delivery device 900. In some of these examples, the machine learning model may be or include a carry position detection model to predict the logical carry position of the aerosol delivery device. And the processing circuit system 906 may be configured to construct the carry position detection model using the machine learning algorithm, at least one feature including acceleration, and a training set generated from measurements of acceleration.
[0170] In other examples where the second sensor(s) 916b include an accelerometer, the target variable may be a gesture performed using the aerosol delivery device 900. In some of these examples, the machine learning model may be or include a gesture recognition model to predict the gesture. And the processing circuit system 906 may be configured to construct the gesture recognition model using the machine learning algorithm, at least one feature including acceleration, and a training set generated from measurements of acceleration.
[0171] In the above and other similar examples, the processing circuit system 906 can be configured to control (multiple) functional elements of the aerosol delivery device 900 based on a user's logical activity, such as predicted, a logical carrying position of the aerosol delivery device, a posture, etc. For example, when the logical activity, carrying position, or posture indicates the use of the aerosol delivery device, the processing circuit system can restore the aerosol delivery device from a sleep mode, or otherwise activate a component that may have been powered off (such as the first sensor 916a). Additionally or alternatively, in examples where the aerosol generating component 910 is or includes a heating component, the processing circuit system can initiate preheating of the heating component.
[0172] In some examples, the user profile may include information describing the authorized user through one or more logical activities, carrying positions and / or postures, which can be used to describe the authorized user, similar to the suction profile of the authorized user. In these examples, in addition to the suction profile or instead of the suction profile, this information can be used to lock the aerosol delivery device 900 for the authorized user. The processing circuit system 906 can predict the logical activities, carrying positions and / or postures during the use of the aerosol delivery device, and compare the predicted logical activities, carrying positions and / or postures with the information in the user profile. When the predicted logical activities, carrying positions and / or postures match the information in the user profile or otherwise have at least a threshold similarity with the information in the user profile, the processing circuit system can enable continued use, and when the predicted logical activities, carrying positions and / or postures do not match or have at least a threshold similarity with the information in the user profile, the aerosol delivery device is locked to prevent continued use.
[0173] In yet another example where the second sensor(s) 916b include an accelerometer, the target variable may be or may be based on a measure of user activity of the aerosol delivery device 900 that is proportional to the number of steps of the user. The number of steps may be determined based on the measurement of acceleration. In some of these examples, the processing circuit system may be configured to build a machine learning model to predict the measure of user activity. Here, the model may be built using a machine learning algorithm, at least one feature including acceleration, and a training set generated from the measurement of acceleration. These steps may be used to determine the relationship between usage of the aerosol delivery device and activity. If usage increases and the measure of activity decreases, the processing circuit system 906 may trigger visual, tactile, and / or audio indicators to encourage the user to increase their activity.
[0174] In some examples where the second sensor(s) 916b include a resistance sensor, the resistance sensor may be a sensor configured to produce a measurement of the resistance of the aerosol precursor composition. The target variable may be a measure of the mass of the aerosol precursor composition that is proportional to the resistivity of the aerosol precursor composition, and the resistivity may be determined based on the measurement of the resistance. Here, the machine learning model may be or include a machine learning model for predicting a measure of the mass of the aerosol precursor composition. The processing circuit system 906 may be configured to construct a machine learning model using a machine learning algorithm, at least one feature including the resistance of the aerosol precursor composition, and a training set generated from the measurement of the resistance.
[0175] Specifically, consider an example embodiment in which the aerosol generating component 910 is or includes a heating component to heat a liquid aerosol precursor composition including a polyol. When the heating component heats the aerosol precursor composition, the amount of polyol can be reduced, which can also reduce the mass of the aerosol precursor composition. This can also reduce the resistivity of the aerosol precursor composition. Given a baseline resistivity of the aerosol precursor composition, a measurement of resistance can be made during use of the aerosol delivery device 900, and the resistivity of the aerosol precursor composition can be determined and compared to the baseline resistivity to determine the mass of the remaining aerosol precursor composition.
[0176] In some examples where power source 908 is rechargeable, the data for multiple uses includes a recharge count and frequency of the power source. In some of these examples, the target variable may be a measure of the expected life of the aerosol precursor composition or the power source that is proportional to the recharge count and frequency of the power source. Processing circuit system 906 may be configured to construct a machine learning model using a machine learning algorithm, at least one feature including the count and frequency of recharges of the power source, and a training set generated from the count and frequency of recharges to predict a measure of the expected life of the aerosol precursor composition or the power source.
[0177] In the above, machine learning and possibly a fuel gauge can be used to predict the life expectancy of the power source 908. If the user frequently uses and recharges the power source, the life expectancy of the power source can be measured as a function of the usage rate. If the usage rate is lower, the power source may have a higher expected life expectancy. In some examples, a fuel gauge may not be used, and the expected life of the number of charges related to the current charge count may be used.
[0178] In some examples where a measure of the expected life of power source 908 is predicted, control of the functional element(s) of aerosol delivery device 900 may include processing circuitry 906 configured to cause the aerosol delivery device to enter a sleep mode when the expected life measurement falls below a threshold time, similar to when the aerosol delivery device is not needed during a period of non-use. Alternatively, the processing circuitry may cause the aerosol delivery device to enter different power saving modes in which components required to use the device to generate an aerosol remain powered, but in which other components may be powered off.
[0179] In examples where the second sensor(s) 916b include a microphone, the microphone may be configured to generate measurements of audio from an audio source in the environment of the aerosol delivery device 900. In some of these examples, the processing circuitry 906 may be further configured to create a virtual directional microphone having a beam pattern created from the measurements of the audio and pointing in the direction of the audio source.
