Description

The present invention relates to aerosol precursor consumables and aerosol delivery devices such as smoking articles, and more particularly to aerosol delivery devices that use electrically generated energy for aerosol production (e.g., electronic cigarettes). The smoking articles may be configured to aerosolize an aerosol precursor, which may incorporate materials made from or derived from tobacco, or incorporate tobacco in any other way, and the precursor may be aerosolized for human consumption. Background of the Invention Many smoking articles have been proposed over the years as improvements to or alternatives for smoking products based on combustible tobacco. Example alternatives have included devices in which a solid or liquid fuel is burned to transfer heat to the tobacco or in which a chemical reaction is used to provide such a heat source. Examples include the smoking articles described in U.S. Patent No. 9,078,473 to Worm et al., which is incorporated herein by reference in its entirety. The point of improvements or alternatives to smoking articles has typically been to provide the sensations associated with smoking cigarettes, cigars, or pipes without supplying substantial amounts of pyrolysis and incomplete combustion products. To this end, numerous smoking products, flavor generators, and medicinal inhalers have been proposed that use electrical energy to vaporize or heat a volatile material or attempt to provide the sensation of smoking cigarettes, cigars, or pipes without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat-generating sources described in the prior art described in U.S. Patent No. 7,726,320 to Robinson et al.; and U.S. Patent Applications Nos. 2013 / 0255702 to Griffith, Jr. et al.; and 2014 / 0096781 to Sears et al., which are incorporated herein by reference.See also, for example, the various types of smoking articles, aerosol delivery devices, and electrically driven heat-generating sources referenced by brand name and trade source in U.S. Patent Application No. 2015 / 0220232 by Bless et al., which is incorporated herein by reference. Additional types of smoking articles, aerosol delivery devices, and electrically driven heat-generating sources referenced by brand name and trade source are listed in U.S. Patent Application opfrpnn / rznz / B / YiAi. No. 2015 / 0245659 of DePiano et al., which is also incorporated herein by reference in its entirety. Other representative cigarettes or smoking articles that have been described and, in some cases, marketed include those described in U.S. Patents Nos. 4,735,217 to Gerth et al.; 4,922,901; 4,947,874 and 4,947,875 to Brooks et al.; U.S. Patents Nos. 5,060,671 to Counts et al.; 5,249,586 to Morgan et al.; 5,388,594 to Counts et al.; 5,666,977 to Higgins et al.; 6,053,176 to Adams et al.; 6,164,287 to White; 6,196,218 to Voges; 6,810,883 by Felter et al.; 6,854,461 by Nichols; 7,832,410 by Hon.; 7,513,253 by Kobayashi; 7,726,320 by Robinson et al.; 7,896,006 by Hamano; 6,772,756 by Shayan; U.S. Patent Applications Nos. 2009 / 0095311 by Hon.; 2006 / 0196518, 2009 / 0126745 and 2009 / 0188490 to Hon.; 2009 / 0272379 by Thorens et al.; 2009 / 0260641 and 2009 / 0260642 by Monsees et al.; 2008 / 0149118 and 2010 / 0024834 of Oglesby et al.; 2010 / 0307518 to Wang; and WO 2010 / 091593 of Hon, which are incorporated herein by reference. Various forms and methods have been proposed for assembling smoking articles having a plurality of sequentially arranged segmented components. See, for example, the various types of assembly techniques and methodologies described in U.S. Patent Nos. 5,469,871 to Barnes et al. and 7,647,932 to Crooks et al.; and U.S. Patent Applications Nos. 2010 / 0186757 to Crooks et al.; 2012 / 0042885 to Stone et al.; and 2012 / 00673620 to Conner et al.; each of which is incorporated herein by reference in its entirety. Certain types of cigarettes that use carbonaceous fuels have been marketed under the brand names Premier, Eclipse, and Revo by RJ Reynolds Tobacco Company. See, for example, the types of cigarettes described in Chemical and Biological Studies on New Cigarette Prototypes that Heat Burn Tobacco, RJ Reynolds Tobacco Company Monograph (1988) and Inhalation Toxicology, 12:5, pp. 1–58 (2000). In addition, a similar type of cigarette has been marketed in Japan by Japan Tobacco Inc. under the brand name Steam Hot One. In some cases, certain smoking articles, particularly those using traditional paper wrapping material, are also prone to burning the paper wrapping material that covers a flammable fuel source, due to the high temperature reached by the fuel source in close proximity to the paper wrapping material. This can reduce the enjoyment of the smoking experience for some consumers and may mask or undesirably alter the flavors delivered to the consumer by the aerosol delivery components of the smoking articles. In other cases, traditional types of smoking articles can produce relatively significant levels of gases, such as carbon monoxide and / or carbon dioxide, during use (e.g., as products of carbon combustion). Still in other cases, traditional types of QPfrpnn / rznz / B / YiAi smoking articles may have poor performance in relation to the aerosolization of the aerosol-forming component(s). As such, it would be desirable to provide smoking devices that address one or more of the technical problems sometimes associated with traditional types of smoking devices. Furthermore, it would be desirable to provide a smoking device that is easy to use and that offers reusable and / or replaceable components.

These and other features, aspects, and advantages of the invention will become apparent from reading the detailed invention described below, together with the accompanying drawings, which are briefly described below. The invention includes any combination of two, three, four, or more of the aforementioned embodiments, as well as combinations of two, three, four, or more features or elements described in this invention, regardless of whether such features or elements are expressly combined in a specific embodiment described herein. This invention is intended to be read holistically, so that any separable feature or element of the disclosed invention, in any of its various aspects and embodiments, should be seen as being combinable unless the context dictates otherwise. Brief Description of the Figures Having thus described the invention in the above general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and in which: FIGURE 1 is a schematic front view of an aerosol delivery device, according to an exemplary modality of the present invention; FIGURE 2 is a schematic front view of an aerosol delivery device, according to an exemplary embodiment of the present invention; FIGURE 3 is a schematic front view of an aerosol delivery device, according to an exemplary modality of the present invention; FIGURE 4 is a schematic front view of an aerosol delivery device, according to an exemplary embodiment of the present invention; and FIGURE 5 is a perspective view of a consumable precursor aerosol, according to an example of an embodiment of the present invention. Detailed Description of the Invention The present invention will now be described in more detail in relation to exemplary embodiments thereof. These exemplary embodiments are described in such a way as to make this invention comprehensive and complete, and to fully convey the scope of the invention to those skilled in the art. In fact, the invention can be implemented in many different ways and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided to enable this invention to satisfy applicable legal requirements. As used in the specification and in the appended claims, the singular forms a, an, and the include plural referents unless the context indicates otherwise. As described below, the embodiments of the present invention relate to aerosol delivery devices or vaporization devices, and these terms are used interchangeably herein. The aerosol delivery devices according to the present invention use electrical energy and / or a flammable heat source to vaporize and / or create an aerosol from a material to be aerosolized; and the components of such devices are in the form of articles that, most preferably, are sufficiently compact to be considered portable devices. In some embodiments, the present aerosol delivery devices can be configured to heat a material (preferably without burning the material to a significant degree and / or without significant chemical alteration of the material) to form the inhalable substance.Preferably, the use of preferred aerosol delivery device components does not result in the production of smoke, i.e., from byproducts of tobacco combustion or pyrolysis, but rather results in the production of vapors from the volatilization or vaporization of certain components incorporated therein. In some embodiments, the aerosol delivery device components may be characterized as electronic cigarettes, and these electronic cigarettes more preferably incorporate tobacco and / or tobacco-derived components and thereby deliver tobacco-derived components in aerosol form. As noted, some embodiments of aerosol delivery devices according to the present invention use electrical energy to energize a material for aerosolization. For example, some embodiments of an aerosol delivery device according to the present invention use electrical energy to heat a material for aerosolization (e.g., electrically heated tobacco products), and other embodiments of aerosol delivery devices according to the present invention use electrical energy to vibrate a material for aerosolization. Still other embodiments of aerosol source elements according to the present invention use a flammable heat source to heat a material for aerosolization (e.g., charcoal-heated tobacco products). The material can be heated without burning it to any significant degree.As such, the subject matter hereunder may be used in a variety of aerosol and / or vapor-producing devices, which may include, but are not limited to, devices commonly known as electronic cigarettes, heat-not-burn (HNB) electronic devices, charcoal-heated tobacco products (cTHP), and electrically heated tobacco products (eTHP). Non-limiting examples of such devices into which any part or all of the present invention may be incorporated are described in U.S. Patent Nos. 839,238; 9,913,493; 10,085,485; and 10,349,674, each of which is incorporated herein in its entirety. QPfrpnn / rznz / B / YiAi The components of such systems are compact enough to be considered portable devices. That is, the use of aerosol delivery device components does not result in the production of smoke in the sense that the aerosol primarily results from byproducts of tobacco combustion or pyrolysis. Rather, the use of these systems results in the production of vapors from the volatilization or vaporization of certain components incorporated within them. In some example modalities, the components of aerosol delivery devices can be characterized as electronic cigarettes, and these electronic cigarettes may incorporate tobacco and / or tobacco-derived components and thus deliver tobacco-derived components in aerosol form. Aerosol delivery devices can provide many of the sensations (e.g., inhalation and exhalation rituals, types of tastes or aromas, organoleptic effects, physical sensation, usage rituals, visual cues such as those provided by a visible aerosol, and the like) of smoking a cigarette, cigar, or pipe used to light and burn tobacco (and thus to inhale tobacco smoke), without any substantial degree of combustion of any of its components. For example, the user of an aerosol-generating device of the present invention can hold and use that piece in much the same way as a smoker uses a traditional type of smoking article, draw on one end of that piece to inhale the aerosol produced by that piece, take or draw puffs at selected time intervals, and so forth. The aerosol delivery devices of the present invention may also be characterized as vapor-producing articles or drug delivery articles. Therefore, such articles or devices may be adapted to provide one or more substances (e.g., flavors and / or active pharmaceutical ingredients) in an inhalable form or state. For example, the inhalable substances may be substantially in vapor form (i.e., a substance that is in the gaseous phase at a temperature below its critical point). Alternatively, the inhalable substances may be in aerosol form (i.e., a suspension of fine solid particles or liquid droplets in a gas). For simplicity, the term aerosol as used herein includes vapors, gases, and aerosols of a form or type suitable for human inhalation, whether visible or not, and in a form that could be considered to be smoke-like. Some aerosol delivery devices of the present invention comprise some combination of a power source (i.e., an electrical power source), at least one control component (e.g., means for activating, controlling, regulating, and stopping the power for heat generation, such as by controlling the flow of electric current from the power source to other components of the article, e.g., a microcontroller or microprocessor), an atomizer, and a liquid composition (e.g., commonly an aerosol precursor liquid composition capable of producing an aerosol upon the application of sufficient heat, such as ingredients commonly referred to as smoke juice, e-liquid). QPfrpnn / rznz / B / YiAi and e-juice), and a nozzle or mouth region to permit extraction of the aerosol delivery device for aerosol inhalation (e.g., a defined airflow path through the article so that the generated aerosol can be removed from it upon extraction). The more specific formats, configurations, and arrangements of the components within the aerosol delivery devices of the present invention will become apparent in light of the further invention provided below. Furthermore, the selection and arrangement of various aerosol delivery device components can be appreciated by considering commercially available electronic aerosol delivery devices, such as the representative products referenced in the background section of the present invention. In FIGURE 1. In general, the aerosol delivery device 100 of the depicted embodiment includes a control unit 200 and a removable consumable aerosol precursor 300. The removable consumable aerosol precursor 300 of the depicted embodiment represents an example of a consumable aerosol precursor in the form of a liquid-composition cartridge; however, aerosol precursor consumables of other embodiments may differ. In the depicted embodiment, the consumable aerosol precursor 300 can be coupled with the control unit 200 to form an operating aerosol delivery device 100, and the consumable aerosol precursor 300 can be removed from it. In the depicted embodiment, the control unit 200 includes a body frame 202 that defines an outer wall of the control unit 204, a distal end of the control unit 206, and a proximal end of the control unit 208. The proximal end of the control unit 208 includes an opening 210 that provides access to a receiving chamber 212, which is defined by an inner control unit frame 214. In the depicted embodiment, the receiving chamber is located near the proximal end 208 of the control unit 200. In some embodiments, the internal frame of the control unit 214 may include an opening 215 that can be configured to transfer pressure differentials through it to a pressure sensor located inside the control unit 200 when air enters the receiving chamber 212. In some embodiments, the pressure sensor may be located on a printed circuit board (PCB) within the control unit. However, in other embodiments, a pressure sensor may be located anywhere. Furthermore, some embodiments do not require a pressure sensor. Example configurations of a PCB and pressure sensor are described in U.S. Patent No. 2015 / 0245658 by Worm et al., which is incorporated herein by reference in its entirety.In several configurations, a pressure sensor can be placed anywhere within the control unit to subject it to an airflow and / or pressure change that can indicate a draw in the device and thus cause the atomizer to activate. QPfrpnn / rznz / B / YiAi The control unit 200 of the represented embodiment also includes a power source, such as a battery 216. Some examples of batteries that may be used according to the invention are described in U.S. Patent Application No. 2010 / 0028766 to Peckerar et al., a description of which is incorporated herein by reference. In the represented embodiment, consumption in the device 100 causes the battery 216 to deliver power to an atomizer located in the consumable aerosol precursor 300. In the absence of a pressure or airflow sensor, the atomizer in some embodiments may be activated manually, such as by means of one or more pushbuttons. Additional examples of sensing or detecting mechanisms, structures, configurations thereof, components thereof, and general methods of operation thereof are described in U.S. Patents Nos. 5,261,424 to Sprinkel, Jr.; 5,372,148 to McCafferty et al.; and PCT WO 2010 / 003480 of Flick; each of which is incorporated herein by reference in its entirety. The control unit 200 of the depicted embodiment also includes at least one control component 218. In the depicted embodiment, the control component 218 is located on a printed circuit board (PCB), and the battery 216 is located within the control unit body frame 202. In the depicted embodiment, the control unit 200 also includes an external connection element 220, which is positioned near the distal end 206 of the control unit body frame 202. Although in various embodiments an external connection element may have a variety of configurations, in the depicted embodiment, the external connection element 220 consists of a plurality of electrical connectors (220a, 220b, 220c). In some embodiments, the control unit may include an output element configured to provide a visually perceptible output signal.In the embodiment shown, for example, the control unit 200 also includes a light source 222, which may comprise, for example, one or more light-emitting diodes (LEDs) capable of emitting one or more colors. In the embodiment shown, the light source 222 is placed directly on the PCB containing the control component 218. In various embodiments, the PCB may include other control components (for example, a microcontroller and / or memory components). In the embodiment shown, the LEDs may, for example, be selected for a design that emits light substantially upward from the plane of the PCB. Alternatively, or additionally, suitable LEDs may include reflector elements adapted or configured to emit light in a substantially different direction, such as parallel to the plane of the PCB, or at a desired angle that provides the desired result.In the represented mode, the pressure sensor and the external connection element 220 are also attached directly to the printed circuit board or otherwise electrically connected to the printed circuit board. QPfrpnn / rznz / B / YiAi In the embodiment shown, the control unit 200 further includes electrical pins 222a and 222b that are positioned in the receiving chamber 212 to form an electrical connection with the consumable aerosol precursor 300 when the consumable 300 is inserted into the receiving chamber 212. As illustrated, the electrical pins 222a and 222b are positioned near the bottom of the receiving chamber 212 and extend through a lower wall of the inner frame 214, which defines the boundaries of the receiving chamber 212. In the embodiment shown, one or more mechanical connectors 224a and 224b are present in the receiving chamber 212 and are positioned in the inner frame 214, and in particular, in its lower wall. In some embodiments, the mechanical connectors may be magnetic elements (e.g., magnets or elements formed from material configured to form a magnetic connection with another magnet).Alternatively, or additionally, the mechanical connectors can be positioned on a side wall of the inner frame and can therefore be configured to establish friction or other mechanical adjustment with a removable and replaceable consumable spray precursor. In several embodiments, the body frame of the control unit 202 can be made of any suitable material, such as metal, plastic, ceramic, glass, or the like. In some embodiments, the internal frame of the control unit is made of the same material as the body frame; however, in other embodiments, different materials may be used. Although the internal frame of the control unit 214 in the depicted embodiment is shown as a separate element from the body frame of the control unit 202, it is understood that, if desired, the internal frame may be defined by an internal surface of the body frame and thus form a common part.Some versions may include an added bottom plate (for example, so that the bottom plate corresponds to the bottom wall of the illustrated inner frame, and the inner surface of the outer casing corresponds to the side wall of the illustrated inner frame). In the depicted embodiment, the control unit 200 is configured to receive a consumable aerosol precursor 300 to provide a functioning aerosol delivery device 100. In the depicted embodiment, the consumable aerosol precursor 300 defines a body including an outer wall 304 and defines a distal end 306 and a proximal end 308. In the depicted embodiment, coupling connectors 310a and 310b are located close to the distal end 306 of the consumable aerosol precursor 300 and are configured to form a connection with mechanical connectors 224a and 224b present in the receiving chamber 212 of the control unit 200. As noted above, the mechanical connectors of the control unit in some embodiments may comprise magnetic elements. As such, the consumable aerosol precursor in some embodiments may include matching magnetic connectors.Alternatively, or additionally, other complementary mechanical connectors can be located in the precursor. QPfrpnn / rznz / B / YiAi of consumable aerosol (e.g., on one or more sides of the outer wall and can therefore be configured to establish a friction fit or other mechanical fit with the receiving chamber of the control unit). In the embodiment depicted, the 300 aerosol precursor consumable is configured to contain an aerosol precursor composition for vaporization, i.e., an e-liquid, which may be configured as described herein. The aerosol precursor composition, sometimes referred to as the aerosol precursor liquid composition, vapor precursor composition, or e-liquid, may comprise a variety of components, which may include, by way of example, polyhydric alcohols (e.g., glycerin, propylene glycol, or a mixture thereof), nicotine, tobacco, a tobacco extract, and / or flavorings. Representative types of aerosol precursor components and formulations are also disclosed and characterized in U.S. Patent No. 7,217,320 to Robinson et al. and U.S. Patent Applications Nos. 2013 / 0008457 to Zheng et al. and 2013 / 0213417 to Chong et al. 2014 / 0060554 by Collett et al.; 2015 / 0020823 by Lipowicz et al.and Koller's 2015 / 0020830, as well as Bowen et al.'s WO 2014 / 182736, the descriptions of which are incorporated herein by reference in full.

BAKER VAPOR and JIMMY THE JUICE MAN. The amount of aerosol precursor incorporated within the aerosol delivery system is such that the aerosol generating device provides desirable performance characteristics and acceptable sensory characteristics. For example, sufficient quantities of aerosol-forming material (e.g., glycerin and / or propylene glycol) may be employed to provide the generation of a visible, mainstream aerosol that in many respects resembles the appearance of tobacco smoke. The amount of aerosol precursor within the aerosol generating system may depend on factors such as the number of puffs desired per aerosol generating device. In one or more embodiments, approximately QPfrpnn / rznz / e / YiAi mi or more, approximately 2 mi or more, approximately 5 mi or more, or approximately mi or more of the aerosol precursor composition. QPfrpnn / rznz / B / YiAi In some of the examples described above, the aerosol precursor composition comprises a glycerol-based liquid. In other embodiments, however, the aerosol precursor composition may be a water-based liquid. In some embodiments, the water-based liquid may be composed of more than approximately 80% water. For example, in some embodiments, the percentage of water in the water-based liquid may be in the inclusive range of approximately 90% to approximately 93%. In some embodiments, the water-based liquid may include up to approximately 10% propylene glycol. For example, in some embodiments, the percentage of propylene glycol in the water-based liquid may be in the inclusive range of approximately 4% to approximately 5%. In some embodiments, the water-based liquid may include up to approximately 10% fragrance.For example, in some formulations, the percentage of flavoring(s) in the water-based liquid may range from approximately 3% to approximately 7%. In some formulations, the water-based liquid may contain up to approximately 1% nicotine. For example, in some formulations, the percentage of nicotine in the water-based liquid may range from approximately 0.1% to approximately 1%. In some formulations, the water-based liquid may contain up to approximately 10% cyclodextrin. For example, in some formulations, the percentage of cyclodextrin in the water-based liquid may range from approximately 3% to 5%. In still other formulations, the aerosol precursor composition may be a combination of a glycerol-based liquid and a water-based liquid.For example, some formulations may contain up to approximately 50% water and less than approximately 20% glycerol. The remaining components may include one or more propylene glycols, flavorings, nicotine, cyclodextrin, etc. Some examples of water-based liquid compositions that may be suitable are described in document GB 1817863.2, filed on November 1. 2018, titled Aerosolable Formulation GB 1817864.0, submitted on November 2018, titled Aerosolable Formulation GB 1817867.3, submitted on November 2018, titled Aerosolable Formulation GB 1817865.7, submitted on November 2018, titled Aerosolable Formulation GB 1817859.0, submitted on November 2018, titled Aerosolable Formulation GB 1817866.5, submitted on November 2018, titled Aerosolable Formulation GB 1817861.6, filed on 1 November 2018, entitled Gel and Crystalline Powder, GB 1817862.4, filed on November 1, 2018, entitled Aerosolisable Formulation-, GB 1817868.1, filed on November 1, 2018, entitled Aerosolisable Formulation; and GB 1817860.8, filed on November 1, 2018, entitled Aerosolisable Formulation, each of which is incorporated by reference in this document in its entirety. In some formulations, the aerosol precursor composition may incorporate nicotine, which may be present in various concentrations.

In the depicted embodiment, the consumable 300 further includes a nozzle portion, defined as a portion of the proximal end 308 of the consumable 300 that a user engages to draw onto the device 100. Although in the depicted embodiment the nozzle portion is an integral part of the consumable body 302, in other embodiments the nozzle portion may be a separate element from the consumable body. In such embodiments, the nozzle portion may be attached to the consumable body. In the depicted embodiment, the aerosol precursor consumable 300 further includes an atomizer 320 configured to aerosolize the aerosol precursor composition and comprising a liquid delivery element 322. In the depicted embodiment, the atomizer 320 comprises a heater, and the liquid delivery element 322 defines a fluid connection between the heater and the liquid in the reservoir 314.In other embodiments, the atomizer may comprise a vibrating assembly (with or without a perforated mesh) and the liquid transport element may define a fluid connection between the vibrating assembly and the liquid in the tank. In the embodiment shown, the atomizer 320 and the liquid transport element 322 are configured as separate elements that are fluidly connected. In other embodiments, these components may be combined. Still other embodiments do not need to include a liquid transport element. In the embodiment shown, the consumable aerosol precursor 300 includes one or more electrical contacts 324a, 324b that are configured to electrically connect the atomizer 320 to the battery 216 in the control unit 200 via contact with the electrical pins 222a, 222b when the consumable aerosol precursor 300 is received in the receiving chamber 212 of the control unit 200. In several embodiments, a liquid transport element may be formed from one or more materials configured for the transport of a liquid, such as by capillary action. In some embodiments, for example, a liquid transport element may be formed from, for example, fibrous materials (e.g., organic cotton, cellulose acetate, regenerated cellulose fabrics, glass fibers), porous ceramics, porous carbon, graphite, porous glass, sintered glass fiber, glass beads, sintered ceramic beads, capillary tubes, or the like. Therefore, the liquid transport element may be any material containing a network of open pores (i.e., a plurality of pores that are interconnected so that the fluid can flow from one pore to another in a plurality of directions through the element). Some embodiments of the present invention may relate particularly to the use of non-fibrous transport elements.As such, the transport elements. Fibrous carriers may be expressly excluded. Alternatively, combinations of fibrous and non-fibrous carrier elements may be used. Representative types of substrates, reservoirs, or other components for supporting the aerosol precursor are described in U.S. Patent No. 8,528,569 to Newton; U.S. Patent Applications Nos. 2014 / 0261487 to Chapman et al.; 2014 / 0059780 to Davis et al.; and 2015 / 0216232 to Bless et al., which are incorporated herein by reference. In addition, various absorbent materials and the configuration and operation of those absorbent materials within certain types of electronic cigarettes are described in U.S. Patent No. 8,910,640 to Sears et al., which is incorporated herein by reference. In some embodiments, a liquid transport element can be formed partially or completely from a porous monolith, such as a porous ceramic, porous glass, or similar material.Examples of monolithic materials suitable for use according to the embodiments of the present invention are described, for example, in U.S. Patent Applications Nos. 2014 / 0123989 to LaMothe and 2017 / 0188626 to Davis et al., descriptions of which are incorporated herein by reference. The porous monolith can form a substantially solid wick. As indicated, in the depicted embodiment, the atomizer 320 comprises a heater. Various materials configured to produce heat when an electric current is applied can be used to form the heater of the depicted embodiment. In some embodiments, for example, the heater may comprise a wire coil. Examples of materials from which the wire coil may be formed include Kanthal (FeCrAl), nichrome, molybdenum disilicide (MoSi2), molybdenum silicide (MoSi), aluminum-doped molybdenum disilicide (Mo(Si,Al)2), titanium, platinum, silver, palladium, silver-palladium alloys, graphite, and graphite-based materials (e.g., carbon-based foams and yarns). In additional embodiments, the heater may be formed from conductive inks, boron-doped silica, and / or ceramics (e.g., ceramics with a positive or negative temperature coefficient).Other types of heaters, such as laser diodes and / or microheaters, can also be used. A laser diode can be configured to deliver electromagnetic radiation at a specific wavelength or band of wavelengths, which can be adjusted for vaporization of the aerosol precursor composition and / or tuned to heat a liquid transport element through which the aerosol precursor composition can be delivered for vaporization. The laser diode can be positioned to deliver electromagnetic radiation within a chamber, and the chamber can be configured to trap the radiation (e.g., a blackbody or a whitebody). Suitable microheaters are described in U.S. Patent No. 8,881,737 to Collett et al., which is incorporated herein by reference.Microheaters, for example, may comprise a substrate (e.g., quartz, silica) with a trace of heater on it (e.g., a resistive element such as Ag, Pd, Ti, Pt). QPfrpnn / rznz / e / YiAi Pt / Ti, boron-doped silicon, or other metals or metal alloys) can be printed or otherwise applied to the substrate. A passivating layer (e.g., aluminum oxide or silica) can be provided over the heater trace. The heater itself can be configured to be substantially flat. Such heaters are described in U.S. Patent Application No. 2016 / 0345633 to DePiano et al., which is incorporated herein by reference. As indicated, the present invention also encompasses other types of atomizers. For example, in some embodiments, an atomizer may comprise one or more elements adapted or configured to vaporize or aerosolize (or form fine particles) from an aerosol precursor liquid without necessarily heating the liquid. For example, a piezoelectric element may be used as a vaporizer in certain embodiments of the present invention, and suitable piezoelectric elements are described, for example, in U.S. Patent Applications Nos. 2013 / 0319404 to Feriani et al. and 2019 / 0014819 to Sur, the description of each of which is incorporated herein by reference in its entirety. In the embodiment depicted, the outer wall 304 of the consumable aerosol precursor 300 is configured to be at least partially transparent or translucent so that the liquid composition contained therein is visible from the outside. As such, in the embodiment depicted, the entire outer wall of the tank 304 is transparent or translucent. Alternatively, only one side of the outer wall of the tank may be transparent, translucent, or tinted, while the remaining portions of the outer wall of the tank may be substantially opaque. In some embodiments, the body frame may include an opening (e.g., a cutout, slit, or notch) to allow viewing of the consumable when it is inserted into the control unit; however, in other embodiments, the opening may be expressly excluded. In some embodiments, the opening may comprise a cutout. Some embodiments of the cutout may be substantially oval in shape; however, it is understood that any shape is encompassed herein. In some embodiments, the opening may be configured as a notch extending from the proximal end of the outer wall of the control unit some distance toward the distal end of the control unit. In other embodiments, the opening may be configured to have no open edges and may therefore expressly exclude a notch configuration as described above.In some embodiments, the opening may be completely open, or the opening may have a transparent member (e.g., glass or plastic) placed in the opening defined by the window or covering the window on one or both of its inner and outer surfaces, or the outer wall of the device. In some embodiments, the housing panel may include one. QPfrpnn / rznz / e / YiAi output feature configured to allow an output signal from the control unit to pass through it. In some configurations, the control unit may include a light window configured to substantially align with the control unit's light source. While some configurations do not require a light window, and others do not require additional components, the control unit may also include a light tube configured to transmit light emitted from the light source through the body frame. Other configurations may include additional features configured to allow light from a light source to pass through them. As indicated, the aerosol delivery device 100 of the represented embodiment includes a control component 218 for controlling the amount of electrical power to the heater during extraction. Representative types of electronic components, their structure and configuration, characteristics, and general methods of operation are described in U.S. Patents Nos. 4,735,217 to Gerth et al.; 4,947,874 to Brooks et al.; 5,372,148 to McCafferty et al.; 6,040,560 to Fleischhauer et al.; 7,040,314 to Nguyen et al.; and 8,205,622 to Pan.

In use, when a consumable aerosol precursor 300 is inserted into the receiving chamber 212 of the control unit 200, the adjustment may be such that air is able to pass between the outer surface 304 of the consumable aerosol precursor 300 and the inner surface of the inner frame 214 of the control unit 200. Therefore, when a user inflates the nozzle portion of the consumable aerosol precursor 300, air can pass between the outer surface 304 of the consumable 300 and the inner surface of the inner frame 214 and through an air inlet 330 in the consumable aerosol precursor 300, mixes with the vapor formed near the atomizer 320, passes through the aerosol conduit 316 and finally exits through an outlet port in the nozzle portion of the consumable aerosol precursor 300.The passage of air as defined above can be effective in causing a pressure drop in the control unit 100 which can be detected by the sensor through the opening 215 in the receiving chamber 212. In some embodiments, the control unit may include one or more display elements, such as a digital screen configured to transmit information to a user. In some embodiments, the control unit may include one or more user input elements, such as one or more buttons configured to operate one or more device functions. In some embodiments, an input element may be included that QPfrpnn / rznz / B / YiAi replaces or complements a pressure or airflow sensor. The input may be included to allow a user to control the device's functions and / or send information to a user. Any component or combination of components may be used as an input to control the function of the control unit 100. For example, one or more pushbuttons may be used as described in U.S. Patent Application No. 2015 / 0245658 to Worm et al., which is incorporated herein by reference. A touchscreen may also be used as described in U.S. Patent Application No. 2016 / 0262454 to Sears et al., which is incorporated herein by reference. As another example, components adapted for gesture recognition based on specific movements of the aerosol delivery device may be used as inputs. See U.S. Patent Application No. 2016 / 0158782 to Henry et al.which is incorporated herein by reference. In some embodiments, an input may comprise a computer or computing device, such as a smartphone or tablet. In particular, the aerosol delivery device may be connected to the computer or other devices, such as by using a USB cable or a similar protocol. The aerosol delivery device may also communicate with a computer or other device acting as an input via wireless communication. See, for example, the systems and methods for controlling a device through a read request as described in U.S. Patent Application No. 2016 / 0007561 by Ampolini et al., the description of which is incorporated herein by reference.In these modalities, an application or other software program in connection with a computer or other computing device may be used to input control instructions to the aerosol delivery device, including such control instructions, for example, the ability to form an aerosol of specific composition by choosing the nicotine content and / or the content of additional flavors to be included, choosing the total particulate matter (TPM) delivered by inhalation, choosing a specific heating profile to implement, choosing a modifiable resistance to draw, and the like. Additional indicators (e.g., a haptic feedback component, an audio feedback component, or the like) may be included in addition to or as an alternative to the LED. Representative additional types of components that produce visual signals or indicators, such as light-emitting diode (LED) components, and their configurations and uses, are described in U.S. Patent Nos. 5,154,192 to Sprinkel et al.; 8,499,766 to Newton; and 8,539,959 to Scatterday; U.S. Patent Application Nos. 2015 / 0020825 to Galloway et al.; and 2015 / 0216233 to Sears et al., which are incorporated herein by reference. It is understood that not all of the illustrated items are required. For example, an LED may be absent or may be replaced by a different indicator, such as a vibrating indicator. QPfrpnn / rznz / e / YiAi As previously stated, in other embodiments, the aroma diffuser may have a different location and / or configuration. For example, FIGURE 2 illustrates an aerosol delivery device 100 according to another exemplary embodiment of the present invention. In general, the aerosol delivery device 100 of the represented embodiment includes a control unit 200 and a removable consumable aerosol precursor 400. The removable consumable aerosol precursor 400 of the represented embodiment represents another example of a consumable aerosol precursor in the form of a liquid, cartridge-type composition; however, the aerosol precursor consumables of other embodiments may differ. In the represented embodiment, the consumable aerosol precursor 400 can be coupled with the control unit 200 to form an operating aerosol delivery device 100, and the consumable aerosol precursor 400 can be removed from it. In the embodiment shown, the control unit 200 is similar to the control unit 200 described in FIGURE 1. Reference is therefore made to that discussion, which will not be repeated here. In the embodiment shown, the consumable aerosol precursor 400 comprises a cartridge containing a liquid composition configured to produce an aerosol by means of electrically generated heat. In other embodiments, other types of consumable aerosol precursors are possible. The consumable aerosol precursor 400 of the embodiment shown defines a body including an outer wall 404 and defines a distal end 406 and a proximal end 408. In the embodiment shown, the coupling connectors 410a and 410b are located near the distal end 406 of the consumable aerosol precursor 400 and are configured to form a connection with the mechanical connectors 224a and 224b present in the receiving chamber 212 of the control unit 200.As noted previously, the mechanical connectors of the control unit in some modalities may comprise magnetic elements. As such, the consumable aerosol precursor in some modalities may include matching magnetic connectors. Alternatively, or additionally, other complementary mechanical connectors may be located in the consumable aerosol precursor (e.g., on one or more sides of the outer wall and thus configured to establish a friction fit or other mechanical fit with the control unit's receiving chamber). In the embodiment shown, the aerosol precursor consumable 400 is configured to contain an aerosol precursor composition for vaporization, i.e., an e-liquid, which can be configured as described herein. Reference is made to the preceding discussion concerning the various possible aerosol precursor compositions and variations thereof.
