Description

Technical Field

[0001] The present disclosure relates to aerosol delivery devices such as electronic cigarettes, and more particularly to aerosol delivery devices including an atomizer. The atomizer can be configured to heat an aerosol precursor composition made from tobacco or incorporating tobacco to form an inhalable substance for human intake.

Background Art

[0002] Over the years, many devices have been proposed as improvements or alternatives to smoking products that require the combustion of tobacco for use. Many of these devices are designed to provide sensations associated with cigarette, cigar, or pipe smoking, but do not supply a significant amount of incomplete combustion and pyrolysis products resulting from the combustion of tobacco. For this purpose, numerous alternative smoking products, aroma generators, and medical inhalers have been proposed that utilize electrical energy to vaporize or heat volatile substances or attempt to provide the sensations of cigarette, cigar, or pipe smoking without significantly burning the tobacco. See, for example, the various alternative smoking products, aerosol delivery devices, and heat sources described in the background art of U.S. Patent No. 8,881,737 to Collett et al., U.S. Patent Application Publication No. 2013 / 0255702 to Griffith Jr. et al., U.S. Patent Application Publication No. 2014 / 0000638 to Sebastian et al., U.S. Patent Application Publication No. 2014 / 0096781 to Sears et al., U.S. Patent Application Publication No. 2014 / 0096782 to Ampolini et al., and U.S. Patent Application Publication No. 2015 / 0059780 to Davis et al., which are hereby incorporated by reference in their entirety. See also the various embodiments of products and heating configurations described in the background art sections of U.S. Patent No. 5,388,594 to Counts et al. and U.S. Patent No. 8,079,371 to Robinson et al., which are hereby incorporated by reference in their entirety.

[0003] However, it may be desirable to provide aerosol delivery devices with additional user control or customization. Therefore, advancements in the functionality of aerosol delivery devices may be desirable. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]

[0044] This disclosure is described more fully below with reference to its exemplary embodiments. These exemplary embodiments are described in such a way that the disclosure is thorough and complete and conveys the entire scope of the disclosure to those skilled in the art. In fact, this disclosure may be embodied in many different forms and should not be construed as being limited to the embodiments described herein, but rather these embodiments are provided to satisfy the legal requirements to which the disclosure is applicable. As used herein and in the appended claims, the singular forms "a," "an," and "the" include the plural form unless otherwise explicitly indicated by context.

[0045] This disclosure provides a description of an aerosol delivery device. An aerosol delivery device can use electrical energy to heat a material (preferably without burning the material to a significant degree) to form an inhalable substance, and such an article is compact enough to be considered most preferably a “handheld” device. Without burning any substantial degree of any component of the article or device, an aerosol delivery device can provide some or all of the sensations of smoking a tobacco, cigar, or pipe (e.g., the manner of inhaling and exhaling, the type of taste or flavor, the sensory effects, the physical sensation, the manner of use, the visual stimuli such as those provided by a visible aerosol). In other embodiments, the aerosol may be invisible, and the aerosol delivery device does not have to produce smoke in the sense of an aerosol resulting from the byproduct of the combustion or pyrolysis of tobacco, but rather, the article or device most preferably produces vapor (including vapor in an aerosol which can be considered a visible aerosol which may be thought to be described as smoke-like) resulting from the volatilization or vaporization of certain components of the article or device. In a very preferred embodiment, the aerosol delivery device can incorporate tobacco and / or tobacco-derived components. Thus, the aerosol delivery device can be characterized as an electronic smoking product, such as an "electronic cigarette."

[0046] While the system is generally described herein in relation to embodiments relating to aerosol delivery devices such as so-called "electronic cigarettes," the mechanisms, components, features, and methods may be embodied in many different forms in relation to various articles. For example, the descriptions provided herein may be used in combination with conventional smoking products (e.g., cigarettes, cigars, pipes, etc.), non-combustible heated tobacco, and related packaging embodiments of any of the products disclosed herein. Thus, the descriptions of mechanisms, components, features, and methods disclosed herein are described merely as examples relating to embodiments of aerosol delivery devices and may be embodied and used in various other products and methods.

[0047] The aerosol delivery devices of this disclosure can also be characterized as vapor product or drug delivery devices. Thus, such articles or devices can be adapted to deliver one or more substances (e.g., flavors and / or pharmaceutically active ingredients) in an inhalable form or state. For example, the inhalable substance may be substantially in the form of a vapor (i.e., a substance in the gas phase at a temperature below its critical point). Alternatively, the inhalable substance may be in the form of an aerosol (i.e., a suspended mass of fine solid particles or droplets in a gas). For simplicity, the term “aerosol” as used herein means including vapors, gases and aerosols in a form or type suitable for human inhalation, whether visible or not, and whether in a form considered fuzzy or smoke-like.

[0048] In use, the aerosol delivery device of the present disclosure is subject to many of the physical actions employed by individuals when using conventional types of smoking products (e.g., cigarettes, cigars, or pipes used by lighting and inhaling a tobacco). For example, a user of the aerosol delivery device of the present disclosure may hold the item like a conventional type of smoking product, inhale one end of the item to inhale the aerosol produced by the item, and puff at selected time intervals.

[0049] The aerosol delivery devices of this disclosure generally include several components housed within an outer shell or body. The overall design of the outer shell or body can vary, and the form or configuration of the outer body can differ, which can define the overall size and shape of the aerosol delivery device. Typically, an elongated body similar in shape to a cigarette or cigar may be formed from a single unit shell, or the elongated body may be formed from two or more separable parts. For example, an aerosol delivery device may be substantially tubular in shape and therefore may include an elongated shell or body that can resemble the shape of a conventional cigarette or cigar. However, in other embodiments, various other shapes and configurations may be employed (e.g., rectangular or fob-shaped).

[0050] In one embodiment, all components of the aerosol delivery device are housed within a single outer body or shell. Alternatively, the aerosol delivery device may include two or more joined and separable shells. For example, an aerosol delivery device may have a control body at one end comprising a shell containing one or more reusable components (e.g., a rechargeable battery and various electronic devices for controlling the operation of the articles thereof), and a shell at the other end comprising a detachably attached disposable component (e.g., a disposable flavor-containing cartridge). More specific forms, configurations, and arrangements of components within a single-shell type unit or a multi-component separable-shell type unit will become apparent in light of further disclosures provided herein. Furthermore, considering commercially available electronic aerosol delivery devices will help to understand the design and component arrangements of various aerosol delivery devices.

[0051] The aerosol delivery apparatus of the present disclosure most preferably includes a power source (i.e., a power source), at least one control component (means for controlling, regulating and / or stopping power for heating, such as by controlling the flow of current from the power source to other components of the aerosol delivery apparatus), a heater or heating component (e.g., an electrical resistance heating element or component commonly referred to as part of the “aerosol atomizer”), and an aerosol precursor composition (e.g., a liquid that can produce an aerosol when sufficiently heated, such as components commonly referred to as “smoke juice”, “e-liquid”, and “e-juice”), and several combinations of a mouth end region or tip that allows inhalation of the aerosol delivery apparatus for aerosol inhalation (e.g., a defined airflow path through the article such that the generated aerosol is drawn out thereupon upon inhalation).

[0052] The arrangement of components within the aerosol delivery device of this disclosure is varied. In certain embodiments, the aerosol precursor composition may be placed near the end of the aerosol delivery device, which may be configured to be placed near the user's mouth to maximize aerosol delivery to the user. However, other configurations are not excluded. Generally, a heating element may be placed close enough to the aerosol precursor composition so that heat from the heating element volatilizes the aerosol precursor (and one or more flavorings, drugs, etc., which may be provided for delivery to the user) and forms an aerosol to be delivered to the user. When the heating element heats the aerosol precursor composition, the aerosol is formed, released, or generated in a physical form suitable for inhalation by the consumer. It should be noted that the terms herein are interchangeable so as to include form or generate, forming or generating, forms or generates, and formed or generated. Specifically, inhalable substances are released in the form of vapors, aerosols, or mixtures thereof, and such terms are also used interchangeably herein unless otherwise specified.

[0053] As described above, the aerosol delivery device may incorporate a battery or other power source that can supply sufficient current to provide various functions to the aerosol delivery device, such as powering the heater, powering the control system, and powering the indicator. The power source can take various embodiments. Preferably, the power source can supply sufficient power to rapidly heat the heating element, provide aerosol formation, and power the aerosol delivery device for a desired duration of use. Preferably, the power source is sized to fit conveniently inside the aerosol delivery device so that the aerosol delivery device can be easily handled. Furthermore, a preferred power source is lightweight enough not to impair the desired smoking experience.

[0054] More specific forms, configurations, and arrangements of the components within the aerosol delivery device of this disclosure will become apparent in light of the further disclosures provided below. Furthermore, the selection of various aerosol delivery device components can be understood by considering commercially available electronic aerosol delivery devices. Furthermore, the arrangement of components within the aerosol delivery device can also be understood by considering commercially available electronic aerosol delivery devices.

For example, the control unit 200 may have a replaceable battery or a rechargeable battery and / or capacitor and can therefore be coupled with any kind of recharging technology, including connection to a typical AC electrical outlet, connection to a car charger (i.e., a cigarette lighter receptacle), and connection to a computer such as a Universal Serial Bus (USB) cable. Furthermore, in some embodiments, the cartridge 300 may include a disposable cartridge, as disclosed in U.S. Patent No. 8910639 to Chang et al., which is incorporated herein by reference in its entirety.

[0058] Figure 2 shows an exploded view of the control body 200 of an aerosol delivery device 100 (see Figure 1) according to an exemplary embodiment of the present disclosure. As shown, the control body 200 may include a coupler 202, an outer body 204, a sealing member 206, an adhesive member 208 (e.g., KAPTON(R) tape), a flow sensor 210 (e.g., a blow sensor or pressure switch), control components 212, a spacer 214, a power supply 216 (e.g., a rechargeable capacitor and / or battery), a circuit board having an indicator 218 (e.g., a light-emitting diode (LED)), a connector circuit 220, and an end cap 222. An example of a power supply is described in U.S. Patent Application Publication No. 2010 / 0028766 by Peckerar et al., the disclosure of which is incorporated herein by reference in its entirety.

[0059] With respect to the flow sensor 210, typical current regulating components, and other current control components including various microcontrollers, sensors, and switches for aerosol delivery devices, are described in U.S. Patent No. 4,735,217 to Gerth et al., U.S. Patents No. 4,922,901, 4,947,874, and 4,947,875 to Brooks et al., U.S. Patent No. 5,372,148 to McCafferty et al., U.S. Patent No. 6,040,560 to Fleischhauer et al., U.S. Patent No. 7,040,314 to Nguyen et al., and U.S. Patent No. 8,205,622 to Pan, all of which are incorporated herein by reference in their entirety. Also referenced is the control scheme described in U.S. Patent Application Publication No. 2014 / 0270727 by Ampolini et al., which is incorporated herein by reference in its entirety.

[0060] In one embodiment, the indicator 218 may include one or more light-emitting diodes. The indicator 218 can communicate with the control component 212 via the connector circuit 220 and illuminate during user inhalation of the cartridge coupled to the coupler 202, for example, as detected by the flow sensor 210. The end cap 222 can be made visible by the indicator 218, allowing the illumination provided underneath to be seen. Thus, the indicator 218 can illuminate during use of the aerosol delivery device 100 to simulate the lit end of the smoking item. However, in other embodiments, the indicator 218 may be provided in various numbers and may take on different shapes, and may even be an opening in the outer body (to emit sound if such an indicator is present).

Various materials disclosed in the aforementioned documents may be incorporated into the apparatus in various embodiments, and all of the aforementioned disclosures are incorporated herein by reference in their entirety.

[0062] Figure 3 shows an exploded view of the cartridge 300 of the aerosol delivery device 100 (see Figure 1). As shown, the cartridge 300 may comprise, according to exemplary embodiments of the present disclosure, a base 302, control component terminals 304, electronic control component 306, flow director 308, sprayer 310, reservoir 312 (e.g., reservoir substrate), outer body 314, mouthpiece 316, label 318, and first heating terminals 320 and second heating terminals 321.

[0063] In some embodiments, the first heating terminal 320 and the second heating terminal 321 may be embedded in the flow director 308 or coupled to the flow director. For example, the first heating terminal 320 and the second heating terminal 321 may be insert-molded within the flow director 308. Thus, the flow director 308 and the first and second heating terminals are collectively referred to herein as the flow director assembly 322. Further description of the first heating terminal 320 and the second heating terminal 321 and the flow director 308 is provided in U.S. Patent Application Publication No. 2015 / 0335071 by Brinkley et al., which is incorporated herein by reference in its entirety.

[0064] The sprayer 310 may include a liquid transport element 324 and a heating element 326. The cartridge may further include a base shipping plug that engages with the base and / or a mouthpiece shipping plug that engages with the mouthpiece, for example, as disclosed in U.S. Patent No. 9,220302 to Depiano et al., which is entirely incorporated herein by reference, in order to protect the base and mouthpiece and prevent contaminants from entering therein before use.

[0065] The base 302 may be coupled to a first end of the outer body 314, and the mouthpiece 316 may be coupled to a second end on the opposite side of the outer body so as to substantially or completely enclose the other components of the cartridge 300 within it. For example, the control component terminals 304, the electronic control component 306, the flow director 308, the sprayer 310, and the reservoir 312 may be substantially or entirely held within the outer body 314. The label 318 may enclose at least partially the outer body 314 and optionally the base 302, and may include information such as a product identifier on it. The base 302 may be configured to engage with the coupler 202 of the control body 200 (see, for example, Figure 2). In some embodiments, the base 302 may include an anti-rotation mechanism that substantially prevents relative rotation between the cartridge and the control body, as disclosed in U.S. Patent Application Publication No. 2014 / 0261495 by Novak et al., which is incorporated herein by reference in its entirety.

[0066] Reservoir 312 may be configured to hold the aerosol precursor composition. Typical types of aerosol precursor components and formulations are also described and characterized in U.S. Patent No. 7,726,320 to Robinson et al., U.S. Patent No. 8,881,737 to Collett et al., and U.S. Patent No. 9,254,002 to Chong et al., U.S. Patent Publication No. 2013 / 0008457 by Zheng et al., U.S. Patent Publication No. 2015 / 0020823 by Lipowicz et al., U.S. Patent Publication No. 2015 / 0020830 by Koller, and International Publication No. 2014 / 182736 by Bowen et al., the contents of which are incorporated herein by reference. Other aerosol precursors that may be used include those incorporated into the VUSE(R) product by RJReynolds Vapor Company, the BLU product by Lorillard Technologies, the MISTIC MENTHOL product by Mistic Ecigs, and the VYPE product by CN Creative Ltd. The so-called "smoke juice" for e-cigarettes, available from Johnson Creek Enterprises LLC, is also desirable. Embodiments of foaming materials can be used in conjunction with aerosol precursors, as exemplified by the U.S. Patent Application Publication No. 2012 / 0055494 by Hunt et al., incorporated herein by reference.Furthermore, the use of foaming materials is described, for example, in U.S. Patent No. 4,639,368 to Niazi et al., U.S. Patent No. 5,178,878 to Wehling et al., U.S. Patent No. 5,223,264 to Wehling et al., U.S. Patent No. 6,974,590 to Pater et al., U.S. Patent No. 7,381,667 to Bergquist et al., U.S. Patent No. 8,424,541 to Crawford et al., U.S. Patent No. 8,627,828 to Strickland et al., U.S. Patent Publication No. 2010 / 0018539 to Brinkley et al., U.S. Patent Publication No. 2010 / 0170522 to Sun et al., and in International Publication No. 97 / 06786 by Johnson et al., all of which are incorporated herein by reference. Further descriptions of embodiments of the aerosol precursor composition, including a description of tobacco or tobacco-derived components contained therein, are provided in U.S. Patent Application No. 15 / 216,582 and U.S. Patent Application No. 15 / 216,590, filed on 21 July 2016, respectively, which are incorporated herein by reference in their entirety.

[0067] The reservoir 312 may include multiple layers of nonwoven fibers formed in the shape of a tube surrounding the inside of the outer body 314 of the cartridge 300. Thus, for example, liquid components can be held sorbently by the reservoir 312. The reservoir 312 is fluidly connected to the liquid transport element 324. Thus, the liquid transport element 324 may be configured to transport the liquid from the reservoir 312 to the heating element 326 via capillary action or other liquid transport mechanisms.

[0068] As shown in the figure, the liquid transport element 324 may be in direct contact with the heating element 326. As further shown in Figure 3, the heating element 326 may include wires defining a plurality of coils wound around the liquid transport element 324. In some embodiments, the heating element 326 may be formed by winding wires around the liquid transport element 324, as described in U.S. Patent No. 9,210738 to Ward et al., which is incorporated herein by reference in its entirety. Furthermore, in some embodiments, the wires may define a variable coil spacing, as described in U.S. Patent No. 9,277770 to DePiano et al., which is also incorporated herein by reference in its entirety. Various embodiments of a material configured to generate heat when an electric current flows through it can be employed to form the heating element 326. Examples of materials on which wire coils can be formed include Kanthal (FeCrAl), nichrome, molybdenum disilicide (MoSi2), molybdenum silicide (MoSi), aluminum-doped molybdenum disilicide (Mo(Si,Al)2), graphite and graphite-based materials, and ceramics (e.g., ceramics with positive or negative temperature coefficients).

[0069] However, various other embodiments of the method can be used to form the heating element 326, and various other embodiments of the heating element can be used in the sprayer 310. For example, a punched heating element can be used in the sprayer as described in U.S. Patent Application Publication No. 2014 / 0270729 by DePiano et al., which is incorporated herein by reference in its entirety. In addition to the foregoing, additional representative heating elements and materials for use therein are described in U.S. Patent No. 5060671 to Counts et al., U.S. Patent No. 5093894 to Deevi et al., U.S. Patent No. 5224498 to Deevi et al., Sprinkel The details are described in U.S. Patent No. 5,228,460 to Jr. et al., U.S. Patent No. 5,322,075 to Deevi et al., U.S. Patent No. 5,353,813 to Deevi et al., U.S. Patent No. 5,468,936 to Deevi et al., U.S. Patent No. 5,498,850 to Das, U.S. Patent No. 5,659,656 to Das, U.S. Patent No. 5,498,855 to Deevi et al., U.S. Patent No. 5,530,225 to Hajaligol, U.S. Patent No. 5,665,262 to Hajaligol, U.S. Patent No. 5,573,692 to Das et al., and U.S. Patent No. 5,591,368 to Fleischhauer et al., the contents of which are incorporated herein by reference in their entirety. Furthermore, in other embodiments, chemical heating may be used. Various further examples of heaters and materials used to form heaters are described in U.S. Patent No. 8,881,737 to Collett et al., which is incorporated herein by reference as described above.

[0070] Various heater components can be used in the aerosol delivery device of the present invention. In various embodiments, one or more microheaters or similar solid heaters can be used. Microheaters and atomizers incorporating microheaters suitable for use in the currently disclosed devices are described in U.S. Patent No. 8,881,737 to Collett et al., which is incorporated herein by reference in its entirety.

[0071] The first heating terminal 320 and the second heating terminal 321 (e.g., negative and positive heating terminals) engage with opposing ends of the heating element 326 and are configured to form an electrical connection with the control body 200 when the cartridge 300 is connected to the control body (see, for example, Figure 2). Furthermore, when the control body 200 is coupled to the cartridge 300, the electronic control component 306 can form an electrical connection with the control body via the control component terminal 304. Thus, the control body 200 can use the electronic control component 212 (see Figure 2) to determine whether the cartridge 300 is genuine and / or to perform other functions. Furthermore, various examples of electronic control components and the functions they perform are described in U.S. Patent Application Publication No. 2014 / 0096781 by Sears et al., which is incorporated herein by reference in its entirety.

[0072] During use, the user can inhale through the mouthpiece 316 of the cartridge 300 of the aerosol delivery device 100 (see Figure 1). This allows air to be drawn in through the control body 200 (see, for example, Figure 2) or an opening in the cartridge 300. For example, in one embodiment, an opening can be defined between the coupler 202 of the control body 200 and the outer body 204, as described in U.S. Patent No. 9,220302 to DePiano et al., which is entirely incorporated herein by reference (see, for example, Figure 2). However, in other embodiments, the airflow can be received through other parts of the aerosol delivery device 100. As described above, in some embodiments, the cartridge 300 may include a flow director 308. The flow director 308 may be configured to direct the airflow received from the control body 200 to the heating element 326 of the atomizer 310.

[0073] A sensor within the aerosol delivery device 100 (for example, a flow sensor 210 in the control unit 200, see Figure 2) can detect puffing. When puffing is detected, the control unit 200 may direct current to the heating element 326 via a circuit including a first heating terminal 320 and a second heating terminal 321. Thus, the heating element 326 can vaporize the aerosol precursor composition that has been guided from the reservoir 312 to the aerosolization zone by the liquid transport element 324. Thus, the mouthpiece 326 can pass air and entrained vapor (i.e., components of the aerosol precursor composition in an inhalable form) from the cartridge 300 to the consumer who inhales it.

[0074] Various other details regarding components that may be included in cartridge 300 are provided, for example, in U.S. Patent Application Publication 2014 / 0261495 by DePiano et al., which is incorporated herein by reference in its entirety. Further components that may be included in cartridge 300 and details relating thereto are provided, for example, in U.S. Patent Application Publication 2015 / 0335071 by Brinkley et al., filed on 23 May 2014, which is incorporated herein by reference in its entirety.

[0075] Various components of the aerosol delivery apparatus described herein can be selected from components described in the art and commercially available. For example, see the reservoir and heater system for controllable delivery of multiple aerosolizable materials in an e-smoking product disclosed in U.S. Patent Application Publication No. 2014 / 0000638 by Sebastian et al., which is incorporated herein by whole reference.

[0076] In another embodiment, the cartridge may be substantially entirely formed from one or more carbon materials, which can offer advantages in terms of biodegradability and the absence of wires. In this regard, the heating element may include carbon foam, the reservoir may include carbonized fabric, and graphite can be used to form electrical connections with power and control components. Exemplary embodiments of carbon-based cartridges are described in U.S. Patent Application Publication 2013 / 0255702 by Griffith et al., which is incorporated herein by reference in its entirety.

[0077] However, in some embodiments, it may be desirable to provide an aerosol delivery device with additional user control. For example, it may be desirable to allow the user to control the type or intensity of flavor of the vapor produced by the aerosol delivery device. Accordingly, embodiments of the present disclosure include features configured to allow the user to customize the operation of the aerosol delivery device.

[0078] In this regard, Figure 4 schematically shows an embodiment of the aerosol delivery device 400 according to an exemplary embodiment of the present disclosure. As shown in Figure 4, the aerosol delivery device 400 may include a power supply 516, one or more sprayers 610, and one or more reservoirs 612. The aerosol delivery device 400 may further include any of the other components described above. Furthermore, the aerosol delivery device 400 may include a sprayer selector 628. As described below, the sprayer selector 628 may be configured to allow the user to customize the vapor produced by the aerosol delivery device 400.

[0079] As shown in the figure, in one embodiment, the aerosol delivery device 400 may include a control body 500, and the control body may include a power supply 516. Furthermore, the aerosol delivery device 400 may include a cartridge 600, and the cartridge may include one or more sprayers 610, one or more reservoirs 612, and a sprayer selector 628. However, in other embodiments, the aerosol delivery device may not include a separate cartridge and control body, or the components of the cartridge and control body may be distributed in different ways. For example, the sprayer selector may be partially or completely included in the control body.

[0080] Figure 5 shows one embodiment of an aerosol delivery device 400' including a plurality of sprayers 610 and a plurality of reservoirs 612. Exemplary embodiments of an aerosol delivery device including a plurality of sprayers are described in their entirety in U.S. Patent Application Publication 2014 / 0000638 by Sebastian et al., which is incorporated herein by reference. Each of the sprayers 610 can be in fluid communication with one of each of the reservoirs 612. Furthermore, a sprayer selector 628 may be configured to provide a selection of one or more sprayers 610 from which an electric current is directed to produce vapor. In this regard, the electric current may be provided by a power supply 516 and selectively directed by the sprayer selector 628 to one or more sprayers 610.

[0081] As can be understood, the sprayer selector 628 can selectively direct current to one or more of the sprayers 610 by any of a variety of mechanisms. In one embodiment, the selective direction of current to one or more sprayers 610 may be done mechanically. In this regard, Figure 6 shows one embodiment of the sprayer selector 628a configured to mechanically select one or more sprayers 610a to which current is directed. The sprayer selector 628a may include one or more guide tracks 630a that can extend parallel to each other. The first and second sprayers 610a', 610a'' (collectively, “sprayers 610a”) may engage with the guide tracks 630a. However, as can be understood, in other embodiments, more sprayers may engage with the guide tracks 630a. Each of the sprayers 610a may include liquid transport elements 624a', 624a'' and heating elements 626a', 626a'' engaged therewith.

[0082] The sprayers 610a may be movable relative to the guide track 630a. Each of the sprayers 610a may be movable simultaneously as a single unit relative to the guide track 630a. In one embodiment, the guide track 630a may move and the sprayers 610a may remain stationary. Alternatively, the guide track 630a may remain stationary and the sprayers 610a may move. In any case, the relative motion between the guide track 630a and the sprayers 610a allows the sprayer selector 628a to selectively form an electrical connection with one or more sprayers. In this regard, each of the guide tracks 630a may include one or more connectors 632a. When one of the sprayers 610a engages with a connector 632a, an electrical connection is formed with the connector, thereby allowing current to be introduced therein. For example, a connector 632a may engage with the end of a heating element of a sprayer 610a.

[0083] In this regard, Figure 6 shows an intermediate configuration of the sprayer selector 628a in which neither sprayer 610a is engaged with the connector 632a. Figures 7 and 8 show overhead views of the sprayer selector 628a in the connected configuration. In particular, Figure 7 shows the sprayer selector 628a and sprayer 610a in a configuration in which the first sprayer 610a' is engaged with the connector 632a. In this configuration, the second sprayer 610a' is electrically disconnected. As a result, the current is directed to the first heating element 626a', which can generate vapor from the aerosol precursor composition held in one of the reservoirs 612a (see Figure 5) that is in fluid communication with the first liquid transport element 624a'. At this time, the current is not directed to the second heating element 626a'', and only the first heating element 626a' can be operated.

[0084] Conversely, Figure 8 shows the sprayer selector 628a and sprayer 610a in a configuration in which the second sprayer 610a'' is engaged with the connector 632a. In this configuration, the first sprayer 610a' is electrically disconnected. This allows current to be directed to the second heating element 626a'', generating vapor from the aerosol precursor composition held in one of the reservoirs 612a (see Figure 5) which is in fluid communication with the second liquid transport element 624a''. In this case, current does not need to be directed to the first heating element 626a' so that only the second heating element 626a'' operates.

[0085] In some embodiments, the sprayer selector 628a may be further configured to change the position of the sprayers 610a with respect to the airflow path through the aerosol delivery device. In this regard, as further shown in Figures 7 and 8, one of the selected sprayers 610a may be positioned within the airflow path through the aerosol delivery device. For example, as shown, in some embodiments, the selected sprayer 610a may be aligned with the flow director 608a by the sprayer selector 628a. Conversely, one or more unselected sprayers 610a may be positioned outside or around the airflow path through the aerosol delivery device.

[0086] In the embodiment described above, the sprayer selector 628a is configured to select one of the sprayers 610a that are electrically connected and located in the air passage. However, in other embodiments, the sprayer selector may be configured to provide a selection of multiple sprayers 610a. For example, Figure 9 shows an embodiment of the sprayer selector 628b in which each guide track 630b includes multiple connectors 632b', 632b''. The sprayers 610b may be movable relative to the guide track 630b so that multiple sprayers can engage with the connectors simultaneously. However, as can be understood, the sprayers 610b may be moved relative to the guide rail to select individual sprayers.

[0087] For example, Figure 10 shows the sprayer selector 628b and sprayer 610b in a configuration in which the first sprayer 610b' is engaged with the first connector 632b'. In this configuration, the second sprayer 610b'' is electrically disconnected, thereby allowing current to be directed to the first sprayer 610b'. Conversely, Figure 11 shows the sprayer selector 628b and sprayer 610b in a configuration in which the second sprayer 610b'' is engaged with the second connector 632b''. In this configuration, the first sprayer 610b' is electrically disconnected, thereby allowing current to be directed to the second heating element 626b''. Thus, one or more of the sprayers 610b can be selected for spraying. As further shown in Figures 9 to 11, the selected sprayer 610b can be aligned with the airflow path through the aerosol delivery device, while the unselected sprayers can be moved outside or to the edge of the airflow path.

[0088] The movement of the sprayer relative to the guide track in the embodiments described above can occur via various actuators. For example, the sprayer can be moved relative to the guide track by rotating a knob. However, in other embodiments, a slider, a switch, or any other actuator may move the sprayer relative to the guide track. Furthermore, although a guide track defining a curved configuration is shown, various other mechanisms may be employed in other embodiments, along with corresponding actuators such as switches, sliders, or any other actuators capable of providing any type of relative motion. Thus, for example, the movement of the sprayer selector and / or sprayer may be linear or rotational and may include axial pushing / pulling and / or rotation of the actuator.

[0089] When the sprayers 610a, 610b engage with the connectors 632a, 632b, feedback may be provided to the user. The feedback may be mechanical. For example, when one of the sprayers engages with one of the connectors, further effort may be required to cause relative motion between the sprayer and the guide track. Additionally or alternatively, the feedback may be electrical. For example, the aerosol delivery device may include an indicator showing which sprayer is engaged with the connector. In another embodiment, the feedback may include tactile feedback, such as that described in U.S. Patent Application Publication 2015 / 0020825 by Galloway et al., which is incorporated herein by reference in its entirety.

[0090] As described above, in one embodiment, the sprayer selector can selectively direct current to one or more sprayers via a mechanical device that can move the sprayers relative to one or more guide tracks. However, in other embodiments, the selective direction of current to one or more sprayers may be done electrically.

[0091] In this regard, Figure 12 shows a sprayer selector 628c according to an additional exemplary embodiment of the present disclosure. In this embodiment, the sprayer selector 628c includes a switch 634c. The sprayer selector 628c may further include a first contact 636c' and a second contact 636c''. The first contact 636c' may be electrically connected to a first sprayer 610c'. The second contact 636c'' may be electrically connected to a second sprayer 610c''. Thereafter, the switch 634c may be used to provide a selection of sprayers 610c', 610c'' to which current is directed. In this regard, as shown in Figure 12, when the switch 634c engages with the first contact 636c', current may be directed to the first sprayer 610c'. Conversely, as shown in Figure 13, when switch 634c engages with the second contact 636c'', current is directed to the second sprayer 610c''.

[0092] Furthermore, in some embodiments, the switch 634c may allow simultaneous selection of multiple sprayers to direct current to multiple sprayers simultaneously, if selected by the user. In this regard, the sprayer selector 628c may further include a third contact 636c''. The third contact 636c'' may be electrically connected to both the first sprayer 610c'' and the second sprayer 610c''. Thus, as shown in Figure 14, when the switch 634c engages with the third contact 636c'''', current can be directed to the first sprayer 610c'' and the second sprayer 610c''. Therefore, the sprayer selector 628c can provide a selection of one or more sprayers 610c', 610c'' to which current can be directed and which can be fluidly communicated with their respective reservoirs 612 to produce vapor therefrom (see Figure 5).

[0093] As shown in Figures 15 to 17, in some embodiments, the sprayer selector 628d may further include a valve 638d configured to selectively direct the airflow path to one or more of the sprayers 610d', 610d''. Figure 15 shows a valve 638d in a neutral configuration, which may be employed when a switch 634d engages with a third contact 636d'''. Thereafter, the airflow can be directed around the valve 638d to each of the sprayers 610d', 610d'', to which current is also directed. However, as shown in Figure 16, if the current is directed to the first sprayer 610d', the valve 638d may block the flow to the second sprayer 610d'', or the airflow directed to the first sprayer 610d'. Conversely, as shown in Figure 17, when current is directed to the second sprayer 610d'', the valve 638d can block the flow to the first sprayer 610d' or block the airflow directed to the second sprayer 610d''.

[0094] Furthermore, although a single valve has been described above to direct the airflow, in another embodiment, the sprayer selector may include multiple valves. For example, as shown in the sprayer selector 628e in Figures 18–20, each sprayer 610e', 610e'' may include its associated valve 638e', 638e''. In a further example, each sprayer 610', 610'' may include its respective flow director 608e', 608e'' configured to direct the airflow thereto, and each flow director may include one of its associated valves 638e', 638e'' so that the airflow can be selectively directed to one or more sprayers.

[0095] In this regard, Figure 18 shows valves 638e' and 638e'' in an open configuration, respectively, so that the airflow is directed through flow directors 608e' and 608e'' to sprayers 610e' and 610e'', respectively. Furthermore, switch 634e is configured to conduct current to each sprayer 610e'', 610e'' via a third contact 636e'''', thereby activating each sprayer. Figure 19 shows a first valve 638e' in an open configuration and a second valve 638e'' in a closed configuration, where the airflow is directed through the first flow director 608e' to the first sprayer 610e', but not through the second flow director 638e to the second sprayer 610e. Furthermore, switch 634e is configured to conduct current only to the first sprayer 610e' via the first contact 636e'. Conversely, Figure 20 shows a second valve 638e'' in an open configuration and a first valve 638e' in a closed configuration, where airflow is directed through the second flow director 608e'' to the second sprayer 610e'' but not through the first flow director 638e' to the first sprayer 610e'. Furthermore, switch 634e is configured to direct current only to the second sprayer 610e' via the second contact 636e''. Thus, in some embodiments, a sprayer selector 628e comprising multiple valves 638e', 638e'' and switch 634e can be used to selectively direct airflow and current to one or more of the sprayers 610e.

[0096] Although the switch is schematically shown as a manual switch, it should be noted that the switch may include a circuit or circuit board that performs the same function. Therefore, for example, in some embodiments, the switch may perform the switching function entirely electronically without requiring mechanical movement. Furthermore, although one or more valves are described as being used to direct airflow to one or more selected sprayers, in other embodiments, the position of the sprayers may be adjusted to move them in and out of the airflow in a manner corresponding to the above.

[0097] Figure 21 shows an aerosol delivery device 700 according to an additional exemplary embodiment of the present disclosure. As schematically shown, the aerosol delivery device 700 may include a power supply 816, one or more atomizers 910, and one or more reservoirs 912. The aerosol delivery device 700 may further include any of the other components described above. Furthermore, the aerosol delivery device 700 may include an additive selector 928. As described later, the additive selector 928 may be configured to allow the user to customize the vapor produced by the aerosol delivery device 700 by providing a selection of one or more additives to be added to the vapor produced by the atomizers 910 from an aerosol precursor composition held in the reservoir 912.

[0098] As shown in the figure, in one embodiment, the aerosol delivery device 700 may include a control body 800, and the control body 800 may include a power supply 816. Furthermore, the aerosol delivery device 700 may include a cartridge 900, which may include one or more sprayers 910, one or more reservoirs 912, and an additive selector 928. However, in other embodiments, the aerosol delivery device does not have to include a separate cartridge and control body, or the components of the cartridge and control body may be distributed in different ways. For example, the additive selector may be partially or completely included in the control body.

[0099] As shown in Figure 22, in some embodiments, the additive selector 928 may be located downstream of the sprayer 910. This allows one or more additives produced by the additive selector 928 to be added to the steam produced by the sprayer 910. However, in other embodiments, the additive selector may be located upstream of the sprayer or at substantially the same position along the airflow path. Thus, the selected steam and additives can be combined regardless of the relative positions of the sprayer 910 and the additive selector 928. However, placing the additive selector 928 downstream of the sprayer 910 may be used, for example, to release the additives from the additive selector 928 due to the heat and / or moisture provided by the steam.

[0100] In some embodiments, the vapor produced by the atomizer 910 may be tasteless and / or lack active ingredients. In this embodiment, the additive selector 928 can add flavorings and / or active ingredients (e.g., pharmaceuticals or nicotine) to it. Thus, the general-purpose aerosol precursor composition can be used with any variety of additives.

[0101] Figure 23 shows one embodiment of the additive selector 928a, which includes a solid bed 940a. As described above, the additive selector 928a, and therefore the solid bed 940a, can be positioned downstream of at least one sprayer 910 (see Figure 22) with respect to the airflow path through the aerosol delivery device 700 (see Figure 21). The solid bed 940 may include a plurality of compartments 942a', 942a'', 942a''' (collectively and generically "compartment 942a"). In this regard, partition 944a may include one or more partitions 946a', 946a'', 946a''' (collectively and generically "partition 946a") separating compartment 942a. In the illustrated embodiment, partition 944a includes three partitions 946a that divide the additive selector 928a into three compartments 942a. However, in other embodiments, a greater or lesser number of partitions and corresponding compartments may be employed.

[0102] Each of the compartments 942a may contain one or more solids 948a', 948a'', 948a''' (collectively and generally referred to as "solid 948a"). In some embodiments, a solid 948a contained in one of the compartments 942a may differ from a solid contained in each of the other compartments. Various embodiments of solid 948a can be used in the solid floor 940a. In one embodiment, solid 948a may include multiple flavoring-containing plastic solids. The solids may be provided in various forms, including, for example, beads, pellets, flakes, or porous monoliths.

[0103] The aerosol delivery device 700, in particular the cartridge 900 (see Figure 21), may further include a flow director. As shown in Figure 23, the flow director 908a can direct the airflow to the additive selector 928a. Thus, with respect to the perspective view shown in Figure 23, the airflow is directed into the page.

[0104] The additive selector 928a may be configured to selectively align the flow director 908a with one or more sections 942a. For example, in Figure 23, the flow director 908a is aligned with the first section 942a'. However, by rotating or moving the additive selector 928a relative to the flow director 908a, the flow director can be selectively aligned with any one of the other sections 942a. This allows the additive selector 928a to add one selected from a plurality of additives to the vapor produced by the atomizer 910 (see, for example, Figure 22). In some embodiments, an actuator (e.g., an electric motor) can move the additive selector relative to the flow director, and in other embodiments, the additive selector can be moved manually relative to the flow director.

[0105] Furthermore, in some embodiments, the flow director 908a may be selectively aligned with multiple compartments 942a. For example, Figure 24 shows the flow director 908a selectively aligned with a portion of the second compartment 942a'' and a portion of the third compartment 942a'''. Thus, multiple additives can be added to the steam simultaneously at several positions of the flow director 908a relative to the additive selector 928a.

[0106] As described above, in some embodiments, the flow director 908a may be aligned with one or more compartments 942a of the additive selector 928a. Thereafter, one or more additives may be added to the steam guided through one or more selected compartments 942a by one or more corresponding solids 948a.

[0107] Figure 25 shows an additional embodiment of the additive selector 928b. As shown, the additive selector 928b may further include one or more additive heating elements 950b', 950b'', 950b''' (collectively and generically, “heating elements 950b”). The additive heating elements 950b may be configured to selectively heat one or more portions of the solid bed 940b. In this regard, the first additive heating element 950b' may be configured to heat the solid 948b' contained in the first compartment 942b', the second additional heating element 950b'' may be configured to heat the solid 948b'' contained in the second compartment 942b'', and the third additive heating element 950b''' may be configured to heat the solid 948b''' contained in the third compartment 942b'''. Thus, one or more additive heating elements 950b can be selectively activated to heat the solid 948b in one or more corresponding compartments 942b. This allows the heat generated by one or more additive heating elements 942b to release one or more additives from the solid bed 940b that are added to the steam generated by the atomizer 910 (see, for example, Figure 22).

[0108] In this embodiment, the additive selector 928b may be stationary relative to the sprayer 910 (see, for example, Figure 22). In this regard, one or more heating elements 950b may generate the additive, and as a result, selective direction of the airflow through one or more portions of the solid bed 940b may not be required. However, in some embodiments, the additive selector 928b may be movable relative to the sprayer 910. Thereafter, the airflow may be directed to one or more sections 942b where the heating elements 950b are activated. Thus, for example, a flow director 908b may be included in the aerosol delivery device 700 (see Figure 21) to direct the airflow to one or more sections 942b where the heating elements 950b are activated.

[0109] In the embodiment shown in Figure 25, an airflow is generated within the page in the illustrated orientation. In this regard, each of the compartments 942b is arranged side by side with the other at the same point along the longitudinal length of the aerosol delivery device. Therefore, the compartments 942b may be distributed laterally across the width of the aerosol delivery device.

[0110] However, the compartments may be positioned relative to each other in other ways. For example, Figure 26 shows one embodiment of the additive selector 928c including a solid bed 940c. As described above, the additive selector 928c, and therefore the solid bed 940c, can be positioned downstream of at least one sprayer 910 (see Figure 22) with respect to the airflow path through the aerosol delivery device 700 (see Figure 21). The solid bed 940c may include a plurality of compartments 942c', 942c'', 942c''' (collectively and generically "compartment 942c"). In this regard, one or more partitions 946c', 946c'' (collectively and generically "partition 946c") can separate compartment 942c. In the illustrated embodiment, two partitions 946c divide the solid bed 940c into three compartments 942c. However, in other embodiments, more or fewer partitions and corresponding compartments may be employed.

[0111] Each of the compartments 942c may contain one or more solids 948c', 948c'', 948c''' (collectively and generically, “solid 948c”). In some embodiments, a solid 948c contained in one of the compartments 942b may differ from a solid contained in each of the other compartments. Various embodiments of solid 948c can be used in the solid floor. In one embodiment, solid 948c may contain multiple flavoring-containing plastic solids. The solids may be provided in various forms, including, for example, beads, pellets, flakes, or porous monoliths.

[0112] The additive selector 928c may further include one or more additive heating elements 950c', 950c'', 950c''' (collectively and generically, "heating elements 950c"). The additive heating elements 950c may be configured to selectively heat one or more portions of the solid bed 940c. In this regard, the first additive heating element 950c' may be configured to heat the solid 948c' contained in the first compartment 942c', the second additional heating element 950c'' may be configured to heat the solid 948c'' contained in the second compartment 942c'', and the third additive heating element 950c''' may be configured to heat the solid 948c''' contained in the third compartment 942c'''. Thus, one or more additive heating elements 950c can be selectively activated to heat the solid 948c in one or more corresponding compartments 942c. As a result, the heat generated by one or more additive heating elements 942c can release one or more additives from the solid bed 940c that are added to the steam generated by the atomizer 910 (see, for example, Figure 22).

[0113] Therefore, the additive selector 928c may be substantially similar to the additive selector 928b in Figure 25. However, as mentioned above, the additive selector 928b in Figure 25 is configured to have compartments 942b distributed laterally across the width of the aerosol delivery device. Thus, the additive selector 928c in Figure 26 differs in that the compartments 942c are distributed longitudinally along the longitudinal length of the aerosol delivery device. In this regard, the airflow can be directed through the first compartment 942c' to the second compartment 942c'' and then into and out of the third compartment 942c''. Therefore, the compartments of the solid bed containing heating elements for releasing the additive can be distributed in any of the following ways, taking into account that the additive will be released into the vapor when one or more heaters are activated. In this regard, the release of the additive does not require a selective airflow through it.

[0114] As described above, in some embodiments of the present disclosure, an aerosol delivery device may include a sprayer configured to generate vapor from an aerosol precursor composition held in a reservoir, and an additive selector including a solid bed configured to add additives to the vapor. Various other details relating to hybrid aerosol delivery devices, including solid embodiments that may be included in the solid bed, are provided in U.S. Patent Application Publication 2015 / 0335070 and National Patent Application Publication 2016 / 0073695 by Sears et al.

[0115] As described above, embodiments of the present disclosure provide an additive selector comprising one or more additive heating elements that heat a solid to produce one or more additives. The solid is generally described above as being contained in a solid bed, but the configuration can be modified in other embodiments. For example, as described above, a flavoring-containing plastic solid can be heated to release the additive. In some embodiments, one or more components of an aerosol delivery device (e.g., a mouthpiece and / or flow director) may include a flavoring-containing plastic. Thereafter, heat from one or more additive heating elements and / or a sprayer can be used to heat one or more components to release the additive. Furthermore, one or more valves can be used to selectively direct air to the components that are heated to produce the additive. In some embodiments, such components including a flavoring-containing plastic may be replaceable or removable to allow the user to replenish or change the additive.

[0116] Figure 27 shows a further embodiment of the additive selector 928d. As shown, the additive selector 928d may include one or more bubble jet heads 952d', 952d'', 952d''' (collectively and generically, “bubble jet head 952d”). The bubble jet head 952d may be configured to provide one or more selections of a plurality of additives to be added to the vapor produced by the atomizer 910 (see, for example, Figure 22).

[0117] Each of the bubble jet heads 952d can be in fluid communication with its respective additive reservoir 954d', 954d'', 954d''' (collectively and generically referred to as "additive reservoir 954d"). Each additive reservoir 954d may contain an additive fluid (e.g., flavorings and / or active ingredients) that can be distributed by the bubble jet head 952d to the vapor produced by the atomizer 910 (see, for example, Figure 22). In some embodiments, the additive fluids held in each of the additive reservoirs 954d may be different from one another. Thus, one or more bubble jet heads 952d can be selectively operated to add one or more additives to the vapor.

[0118] Figure 28 illustrates a further embodiment of the aerosol delivery device 700e. As shown, the sprayer 910e may include a venturi nozzle 956e. When a user inhales into the aerosol delivery device 700e, the aerosol precursor composition can be drawn in from the reservoir 912e through the venturi nozzle 956e. The venturi nozzle 956e may include a throttle 958e that accelerates the flow of the aerosol precursor composition through it and creates a low-pressure region. The low pressure allows outside air to be drawn in through the air inlet 960e to mix with the aerosol precursor composition to generate vapor.

[0119] Furthermore, the additive selector 928e may be configured to provide a selection of one or more additives to be added to the steam. In this regard, the additive selector 928e may include a plurality of channels 962e', 962e'' (collectively and generically "channel 962e"), each configured to be in fluid communication with one of a plurality of additive reservoirs 954e', 954e'' (collectively and generically "additive reservoir 954e"), and can be selectively configured to be in fluid communication with a venturi nozzle 956e.

[0120] In this regard, the additive selector 910e may further include an additive valve 964e. The additive valve 964e may include at least one opening 966e configured to selectively align with one or more channels 962e. For example, in Figure 28, the first channel 962e' is in fluid communication with the venturi nozzle 956e via the opening 966e of the additive valve 964e, while the second channel 962e'' is not in fluid communication with the venturi nozzle. Conversely, in Figure 29, the second channel 962e'' is in fluid communication with the venturi nozzle 956e via the opening 966e of the additive valve 964e, while the first channel 962e' is not in fluid communication with the venturi nozzle.

[0121] Therefore, when one or more channels 962e are in fluid communication with the venturi nozzle 956e and the user draws in with the aerosol delivery device 700e, the low pressure of the throttle 958e can draw fluid additives from each fluid-communicating additive reservoir 954e to the venturi nozzle. This allows one or more fluid additives to be vaporized and added to the vapor generated from the aerosol precursor composition received from the reservoir 912e. It should be noted that the throttle 958e and / or channels 962e may include capillaries configured to resist the flow through them, except when the user draws them in with the aerosol delivery device 700e to prevent leakage.

[0122] Figure 30 shows a further embodiment of the additive selector 928f. As shown, the additive selector 928f may include at least one additive reservoir 954f', 954f'' (collectively and generically, “additive reservoir 954f”). Each additive reservoir 954f may contain an additive fluid (e.g., flavorings and / or active ingredients). In some embodiments, the additive fluids held in each of the additive reservoirs 954f may differ from one another.

[0123] Each additive reservoir 954f can be in fluid communication with its respective channel 962f', 962f'' (collectively and generically referred to as "channel 962f"). In the illustrated embodiment, the additive selector 928f includes two additive reservoirs 954f and two corresponding channels 962f. However, in other embodiments, more or fewer additive reservoirs and channels may be used.

[0124] As shown in Figure 30, the additive selector 928f may further include at least one crystal oscillator 968f. The crystal oscillator 968f may be configured to vibrate ultrasonically in contact with one or more channels 962f and / or the additive fluid contained therein. For example, in one embodiment, the crystal oscillator 968f may be equipped with a vibrating screen that fluid-communicates with one or more of the channels 962f. This allows the additive fluid in one or more channels 962f in contact with the crystal oscillator 968f to be sprayed, producing one or more additives to be added to the vapor produced by the atomizer 910 (see, for example, Figure 22). In one embodiment, a separate crystal oscillator can be associated with each channel, thereby allowing the crystal oscillator to be selectively operated to produce one or more additives. In another embodiment, a single-crystal oscillator can be used to selectively spray the additive fluid in one or more channels.

[0125] In this regard, the crystal oscillator 968f may be movable relative to channel 962f. For example, Figure 31 shows the crystal oscillator 968f in contact with the first channel 962f' to spray a fluid additive held in the first additive reservoir 954f'. However, as can be understood, the crystal oscillator 968f may be moved relative to the second channel 962f'' to spray an additional or alternative fluid additive held in the second additive reservoir 954f''.

[0126] The embodiments of the additive selectors 928d to f described above, with respect to Figures 27 to 31, can produce additives with relatively large droplet sizes. In embodiments where the additive is configured to provide flavor, the use of relatively large droplets or particles may be desirable. In this regard, relatively large droplets and particles may be more easily recognized by flavor receptors and therefore may provide a stronger flavor.

[0127] The embodiments of the aerosol delivery device described above include an additive selector. In some embodiments, the additive selector or a part thereof (e.g., a solid bed) may be removable, refillable, and / or interchangeable. This allows for the replenishment of additives or their replacement with different types. In some embodiments, the additives may be configured for single use (e.g., one puff), which may be useful when the additives contain a drug to provide the correct dosage without the risk of overdose.

[0128] The embodiments of the aerosol delivery device described above include a plurality of sprayers. In some embodiments, two or more sprayers can be operated simultaneously. In these embodiments, the amount of vapor produced by the sprayers can be adjusted. For example, the amount of current supplied to each sprayer may be individually adjustable by the user. Furthermore, in some embodiments of the aerosol delivery device described above that include a plurality of sprayers, the sprayers or their components (e.g., liquid transport elements and / or heating elements) may be of different sizes so that two or more sprayers have different sizes and / or other characteristics.

[0129] In the embodiments described above, various sprayer selectors are employed to select sprayers, additives, valves, etc., in order to customize the operation of the aerosol delivery device. Such selections can be made mechanically, electrically, or a combination thereof. In some embodiments, an application may be provided that enables a mobile phone or other electronic device to communicate with the aerosol delivery device and make such selections through that application. Thereafter, in some embodiments, the sprayer selector can be controlled via the application.

[0130] As described above, various embodiments of the additive can be employed. For example, the additive may contain active ingredients such as flavorings or pharmaceuticals (e.g., albuterol or nicotine). Examples of flavors include vanillin, ethyl vanillin, cream, black tea, coffee, fruit (e.g., banana, berry, apple, cherry, strawberry, peach, and citrus flavors, including lime and lemon), maple, menthol, chocolate, mint, peppermint, spearmint, wintergreen, nutmeg, clove, lavender, cardamom, ginger, honey, anise, sage, cinnamon, sandalwood, jasmine, cascaria, cocoa, licorice, and flavors of the types and characteristics traditionally used to flavor tobacco, cigars, and pipe tobacco.

[0131] In a further embodiment, a method for vapor generation using an aerosol delivery device is provided. As shown in Figure 32, the method may include providing a selection of one or more atomizers in operation 1002. Furthermore, the method may include changing the position of the atomizers with respect to the airflow path through the aerosol delivery device in operation 1004. The method may further include, in operation 1006, passing an electric current to the one or more atomizers selected to generate vapor.

[0132] In some embodiments, changing the position of the atomizers relative to the airflow path through the aerosol delivery device in operation 1004 may include selectively directing the airflow path to one or more atomizers selected by a valve. Furthermore, directing an electric current to one or more atomizers selected to generate vapor in operation 1006 includes selectively forming an electrical connection with the selected one or more atomizers. The method may further include providing one or more of a selection of a plurality of additives and adding the selected one or more additives to the vapor.

[0133] In a further embodiment, a method for generating vapor using an aerosol delivery device is provided. As shown in Figure 33, the method may include providing one or more selections of a plurality of additives in operation 1102. Furthermore, the method may include generating vapor from the aerosol precursor composition using at least one atomizer in operation 1104. The method may further include adding the selected one or more additives to the vapor.

[0134] In some embodiments, the method may further include forming one or more additives from a solid bed. Providing a selection of one or more additives in operation 1102 may include providing selective alignment of a venturi nozzle with one or more channels that fluidly communicate with one of a plurality of additive reservoirs. Furthermore, adding the selected one or more additives to the vapor in operation 1106 may include operating at least one crystal oscillator. Producing the vapor using at least one atomizer in operation 1104 may include providing a selection of one or more atomizers. The method may further include repositioning the atomizers with respect to the airflow path through the aerosol delivery device and directing an electric current to the selected one or more atomizers to generate the vapor.

Therefore, it should be understood that this disclosure is not limited to the specific embodiments disclosed herein, and that modifications and other embodiments are intended to be included within the scope of the appended claims.
