Abstract
Description
[Technical Field]
[0001] The present disclosure relates to an aerosol delivery device, and more particularly, to an aerosol delivery device including a housing and a coupler. The aerosol delivery device may include a nebulizer with a heating element configured to heat an aerosol precursor. The aerosol precursor composition, which may include components made from, derived from, or otherwise incorporating tobacco, is heated by the nebulizer to produce an inhalable substance for human consumption. [Background technology]
[0002] Many smoking devices have been proposed over the years as an improvement or replacement for smoking products that require the burning of tobacco for use. Many of these devices are intentionally designed to provide the sensation associated with smoking cigarettes, cigars, or pipes, but without delivering significant amounts of incomplete combustion and pyrolysis products resulting from the burning of tobacco. To this end, many smoking products, flavor generators, and medicament inhalers have been proposed that utilize electrical energy to vaporize or heat volatile materials, or that attempt to provide the sensation of smoking cigarettes, cigars, or pipes without burning significant amounts of tobacco. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat sources described in the background section of U.S. Pat. Nos. 7,726,320 to Robinson et al. and 8,881,737 to Collett et al., the contents of which are incorporated herein by reference. See also, for example, U.S. Patent Application Publication No. 2015 / 0216232 to Bless et al., for the various types of smoking articles, aerosol delivery devices, and electrically powered heat sources referenced in branded and commercial sources. The contents of this patent are incorporated herein by reference. Additionally, various types of powered aerosol and vapor delivery devices have been proposed in U.S. Patent Application Publication No. 2014 / 0096781 to Sears et al. and U.S. Patent Application Publication No. 2014 / 0283859 to Minskoff et al., as well as U.S. Patent Application No. 14 / 282,768 to Sears et al., filed May 20, 2014, U.S. Patent Application No. 14 / 286,552 to Brinkley et al., filed May 23, 2014, U.S. Patent Application No. 14 / 327,776 to Ampolini et al., filed July 10, 2014, and U.S. Patent Application No. 14 / 465,167 to Worm et al., filed August 21, 2014, the contents of which are incorporated herein by reference.
[0003] Certain existing embodiments of an aerosol delivery device include a regulator and a cartridge. A power source (e.g., a battery) may be positioned within the regulator, and the aerosol precursor composition may be positioned within the cartridge. The cartridge and regulator may engage with each other to define an elongated tubular configuration. However, certain other shapes for the aerosol delivery device may be desirable.

[0044] The present disclosure is described in more detail below with reference to exemplary embodiments. These exemplary embodiments are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, this disclosure may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. As used in this specification and the appended claims, the singular forms "a," "an," and "the" include the plural forms unless the context clearly dictates otherwise.
[0045] The aerosol delivery device of the present disclosure may use electrical energy to heat materials (preferably without significantly burning the materials) to form an inhalable substance. Most preferably, such articles are compact enough to be considered "portable" devices. The aerosol delivery device may provide some or all of the sensations of smoking a cigarette, cigar, or pipe (e.g., the act of inhaling and exhaling, the type of flavor or flavoring, the sensory stimulating effect, the physical feel, the manner of use, the visual stimuli such as those provided by a visible aerosol, etc.) without significantly burning any components of the article or device. The aerosol delivery device may not produce smoke in the sense of an aerosol resulting from the by-products of tobacco combustion or thermal decomposition. Rather, most preferably, the article or device generates vapors resulting from the volatilization or vaporization of certain components of the article or device (including vapors within the aerosol that may be considered a visible aerosol, which may be considered to be in a state described as smoke-like), although in other embodiments, the aerosol may not be a visible aerosol. In highly preferred embodiments, the aerosol delivery device may incorporate tobacco and / or tobacco-derived components. Thus, the aerosol delivery device may be characterized as an electronic smoking article, such as an e-cigarette.
[0046] The aerosol delivery device of the present disclosure may also be characterized as a vapor product or drug delivery article. Accordingly, such an article or device may be adapted to provide one or more substances (e.g., flavorings and / or active pharmaceutical ingredients) in an inhalable form or state. For example, the inhalable substance may be substantially in vapor form (i.e., a substance in a gaseous state at a temperature below its critical point). Alternatively, the inhalable substance may be in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). For simplicity, the term "aerosol" as used herein is intended to include vapors, gases, and aerosols in any form or type suitable for human inhalation, regardless of whether they are visible or in a form that can be considered smoky.
[0047] The aerosol delivery device of the present disclosure can undergo many of the physical actions taken by a person when using a traditional type of smoking article (e.g., a cigarette, cigar, or pipe used by lighting and inhaling tobacco. For example, the aerosol delivery device of the present disclosure can be carried by a user, who can inhale a portion of the article for inhalation of the aerosol produced by the article, and who can smoke the cigarette at selected time intervals.
[0048] The aerosol delivery device of the present disclosure generally includes a housing and several additional components coupled to and / or positioned within the housing, some of which may be removable or replaceable. The overall design of the housing may vary, and the overall size and shape of the housing may vary. The smoking article may include a cartridge, which may be defined by an outer body or cover (e.g., an elongated body resembling the shape of a portion of a cigarette or cigar). For example, the outer cover or body of the cartridge may be substantially tubular in shape, resembling the shape of a traditional cigarette or cigar. In some embodiments, the housing may house one or more reusable components (e.g., a rechargeable battery and various electronics for controlling the operation of the article), and the cartridge may be removable, refillable, and / or disposable.
[0049] The aerosol delivery device of the present disclosure most preferably comprises some combination of a power source (i.e., a power source), at least one control component (e.g., a means for activating, controlling, regulating, and / or terminating power for heat generation, e.g., by controlling the flow of electrical current from the power source to other components of the aerosol delivery device), a heater or heat-generating component (e.g., an electrical resistance heating element or component commonly referred to as part of an "atomizer"), an aerosol precursor composition (e.g., a liquid capable of generating an aerosol upon application of sufficient heat, such as the components commonly referred to as "smoke juice," "e-liquid," and "e-juice"), and a mouthpiece region or tip (e.g., a predetermined air flow path through the article through which the generated aerosol can be drawn upon drawing) to enable the aerosol delivery device for aerosol inhalation. When the heating element heats the aerosol precursor composition, an aerosol is formed, emitted, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the above terms are intended to be interchangeable, with the terms release, releasing, releases, and released including form or generate, forming or generating, forms or generates, and formed or generated. Specifically, the inhalable substance is released in the form of a vapor or an aerosol, or a mixture thereof.
[0050] As described above, the aerosol delivery device may incorporate a battery and / or power source (e.g., a capacitor) to provide sufficient current to provide various functionalities to the aerosol delivery device, such as powering a heater, powering a control system, and powering indicators. The power source may take various forms. Preferably, the power source is capable of providing sufficient power to rapidly heat the heating element to effect aerosol formation and to power the aerosol delivery device for the desired duration of use. The power source is preferably sized to fit conveniently within the aerosol delivery device for ease of operation. Furthermore, suitable power sources are sufficiently lightweight so as not to detract from the desired smoking experience. The battery used in the device may be replaceable, removable, and / or rechargeable, and thus may be compatible with any type of charging technology, including connection to a typical alternating current electrical outlet, connection to a car socket charger (i.e., cigarette lighter socket), and connection to a computer, such as via a universal serial bus (USB) cable or connector. In one preferred embodiment, the power source comprises a lithium-ion battery, which is lightweight, rechargeable, and can provide a large energy storage capacity. An example power supply is described in U.S. Patent Application Publication No. 2010 / 0028766 to Peckerar et al., the entire disclosure of which is incorporated herein by reference.
[0051] Aerosol delivery devices according to the present disclosure preferably incorporate a sensor or detector for controlling the supply of power to the heating element when aerosol generation is desired (e.g., when in use, when inhaling). Thus, for example, a manner or method is provided for turning off the power supply to the heating element when the aerosol-generating piece is not being inhaled during use, and turning on the power supply to activate or initiate heat generation by the heating element upon inhalation. For example, with respect to flow sensors, representative current regulation components and other current control components, including various microcontrollers, sensors, and switches for aerosol delivery devices, are described in U.S. Pat. No. 4,735,217 to Gerth et al., U.S. Pat. No. 4,947,874 to Brooks et al., U.S. Pat. No. 5,372,148 to McCafferty et al., U.S. Pat. No. 6,040,560 to Fleischhauer et al., U.S. Pat.

[0052] In some embodiments, the aerosol delivery device can include an indicator, which can include one or more light-emitting diodes, that can illuminate, for example, during a user's draw on the mouthpiece as detected by the flow sensor, in communication with the control component via a connector circuit.
[0053] Various elements that may be included in the housing are described in U.S. Patent Application Publication No. 2015 / 0245658 to Worm et al., the entire contents of which are incorporated herein by reference.

[0055] The aerosol delivery device preferably includes a reservoir. In some embodiments, the reservoir may comprise a container for storing a liquid aerosol precursor, a fibrous substrate, or a combination of a fibrous substrate and a container. A fibrous substrate suitable for use as a reservoir may include multiple layers of nonwoven fibers and may be formed into a substantially tubular shape. For example, the formed tube may be shaped and sized for placement within the outer body or cover of a cartridge for use in the aerosol delivery device. The liquid component may be, for example, sorbently held by the fibrous substrate and / or held within the reservoir container. The reservoir is preferably in fluid communication with a liquid transfer element. Thus, the liquid transfer element may be configured to transfer liquid from the reservoir to the heating element, for example, by capillary action and / or active transfer (e.g., pumping or controlled movement by a valve). Representative types of substrates, reservoirs, or other components for supporting aerosol precursors are described in U.S. Patent No. 8,528,569 to Newton and U.S. Patent Application Publication No. 2014 / 0261487 to Chapman et al., U.S. Patent Application Publication No. 2014 / 0004930 to Davis et al., and U.S. Patent Application Publication No. 2015 / 0216232 to Bless et al., the entire contents of which are incorporated herein by reference.
[0056] The liquid transfer element may be in direct contact with the heating element.

The heating element can include wires establishing a mesh, screen, or lattice structure positioned around the liquid transfer element. Examples of materials from which the wire mesh, screen, or lattice can be formed include titanium, platinum, silver, palladium, Kanthal (FeCrAl), nichrome, molybdenum disilicide (MoSi), molybdenum silicide (MoSi), aluminum-doped molybdenum disilicide (Mo(Si,Al)), graphite and graphite-based materials, and ceramics (e.g., ceramics with positive or negative temperature coefficients). One example embodiment of a mesh heating element is disclosed in U.S. Patent Application Publication No. 2015 / 0034103 to Hon.

Additionally, in other embodiments, chemical heating may be used. Various other examples of heaters and materials used to form heaters are described in U.S. Patent No. 8,881,737 to Collett et al., the entire contents of which are incorporated herein by reference.
[0058] A variety of heater components can be used in the aerosol delivery device of the present invention. In various embodiments, one or more microheaters or similar solid-state heaters can be used. Microheaters suitable for use in the devices of the present disclosure and embodiments of nebulizers incorporating microheaters are described in U.S. Patent No. 8,881,737 to Collett et al., the entire contents of which are incorporated herein by reference.
[0059] One or more heating terminals (e.g., positive and negative terminals) can be connected to the heating element to form an electrical connection with a power source, and / or the terminals can be connected to one or more control elements of the aerosol delivery device. Further, various examples of electronic control components and functions performed by electronic control components are described in U.S. Patent Application Publication No. 2014 / 0096781 to Sears et al., the entire contents of which are incorporated herein by reference.
[0060] The various components of the aerosol delivery device according to the present disclosure can be selected from those that are well-known in the art and are commercially available. See, for example, U.S. Patent Application Publication No. 2014 / 0000638 to Sebastian et al., which discloses a reservoir and heater system for controllable delivery of multiple aerosolizable materials in an electronic smoking article. The entire contents of this patent are incorporated herein by reference.
[0061] In further embodiments, one or more components of the aerosol delivery device may be formed from one or more carbon materials, which may offer the advantages of being biodegradable and wire-free. In this regard, the heating element may include carbon foam, the reservoir may include carbonized fabric, and graphite may be used to form electrical connections with the battery and controller. One exemplary embodiment of a carbon-based cartridge is described in U.S. Patent Application Publication No. 2013 / 0255702 to Griffith et al., the entire contents of which are incorporated herein by reference.
[0062] Aerosol delivery devices are often configured to mimic the appearance of certain traditional smoking articles, such as cigarettes or cigars. In this regard, aerosol delivery devices typically define a substantially cylindrical configuration. For example, aerosol delivery devices often include a control body and a cartridge attached end-to-end to define a substantially cylindrical configuration. While such configurations may provide a look and feel similar to traditional smoking articles, they may suffer from certain disadvantages. For example, aerosol delivery devices with a cylindrical configuration may not define attachment points that can be used to hold the aerosol delivery device in a desired position when not in use. Furthermore, such configurations, when used with a reservoir having a relatively large capacity similar to the size and shape of a cigar, can result in a relatively large device that may not be suitable for temporary storage or transport within a user's pocket.
[0063] So-called "modern" devices may include configurations of the regulator and cartridge that are not parallel and coaxial. However, such devices may include exposed and / or poorly supported electrical connectors connecting the regulator and cartridge, which may become distorted during use or storage, potentially affecting their usefulness. Therefore, it may be desirable to provide aerosol delivery devices with configurations and shapes that differ from those associated with conventional smoking articles and conventional aerosol delivery devices.
[0064] Thus, embodiments of the present disclosure provide an alternative aerosol delivery device configured to address the above-mentioned shortcomings of existing aerosol delivery device configurations and / or provide other benefits. FIG. 1 is a side view of an aerosol delivery device 100 of the present disclosure. As shown, the aerosol delivery device 100 may include a control body 101, which may include a housing 102. In some embodiments, the housing may include a plastic material, although in other embodiments, various other materials, preferably substantially rigid, may be used. The housing 102 may be a single housing or may comprise multiple pieces. For example, the housing 102 may include a main body 102a, which may itself include one or more pieces, and an opening / closing door 102b. As further shown in FIG. 1, the aerosol delivery device 100 may further include a cartridge 200, which may be at least partially received within the control body 101.
[0065] 2 is a partially exploded cross-sectional view of the control body 101 of the aerosol delivery device 100. As shown, the housing 102 can define a power source cavity 104. In particular, the power source cavity 104 can be defined within a body portion 102a of the housing 102. The power source cavity 104 can be enclosed by and accessed through a hinged door 102b. As described below, the power source cavity 104 can be configured to receive a power source.
[0066] Additionally, the housing 102 may define a cartridge cavity 106. As described in detail below, the cartridge cavity 106 may be configured to receive a cartridge 200 (see, for example, FIG. 3). In this regard, the housing 102 may define an exterior opening 108 to the cartridge cavity 106 configured to receive the cartridge 200 therethrough.
[0067] The housing 102 may include a septum 107 that separates the power source cavity 104 from the cartridge cavity 106. In some embodiments, the septum 107 completely separates the power source cavity 104 from the cartridge cavity 106. For example, the septum 107 may extend the length and thickness of the control body 101 such that the power source cavity 104 and the cartridge cavity 106 are separate cavities. This configuration may be preferable in that it may prevent fluid communication between the power source cavity 104 and the cartridge cavity 106. This may prevent chemical intrusion into the cartridge cavity 106, for example, in the event of a structural defect in the power source. However, as may be appreciated, in other embodiments, the septum may be discontinuous in either or both length and compatibility. Such a septum configuration may securely hold the power source within the power source cavity and the cartridge within the cartridge cavity, respectively, thereby holding these components in place.
[0068] The control body 101 may include one or more additional components. The components may be received within or otherwise engaged with the housing 102. For example, the components may include an electrical circuit, the operation of which is described below. The electrical circuit may include the controller 110, first and second electrical contacts 112a, 112b, and a coupler 114. In some embodiments, the electrical circuit may further include an electronic display 116 (e.g., a liquid crystal display). Additionally, the electrical circuit may include a flow sensor 118, which may be positioned on or in fluid communication with the coupler 114. Wires or other electrical connectors may provide connections between the various components of the electrical circuit. In some embodiments, the electrical circuit may further include a communications module. The communications module may be configured to communicate via Bluetooth or any other communications standard. Examples of communication modules and associated antenna components that may be included in the aerosol delivery device 100 are described in U.S. patent application Ser. No. 14 / 802,789 to Marion et al., filed July 17, 2015, and U.S. patent application Ser. No. 14 / 638,562 to Marion et al., filed March 4, 2015.
[0069] 3 is a cross-sectional view of the aerosol delivery device 100. As shown, the cartridge 200 may be at least partially received within the cartridge cavity 106 when engaged with the control body 101. In this regard, the cartridge 200 may be inserted into the cartridge cavity 106 through the exterior opening 108. Once the cartridge 200 is inserted into the cartridge cavity 106, the cartridge 200 may engage with the coupler 114. This allows the cartridge 200 to establish an electrical connection with the control circuitry such that electrical current may be selectively directed by the controller 110 to the cartridge to generate aerosol.
[0070] 3, the aerosol delivery device 100 may further include a power supply 300. The power supply 300 may be received within the power supply cavity 104, and the door 102b may be secured to the main body 102a of the housing 102 such that the power supply 300 is retained in the power supply cavity 104. In this regard, the aerosol delivery device 100 may further include at least one fastener 120 (e.g., a screw) configured to hold the door 102b in engagement with the main body 102a of the housing 102.
[0071] When the power supply 300 is inserted into the power supply cavity 104, the first electrical contact 112a can engage a first end of the power supply, and a first terminal of the power supply can be positioned at that location. Thereafter, when the door 102b is secured to the body 102, the second electrical contact 112b can engage an opposing second end of the power supply 300, and a second terminal can be positioned at that location. This allows power from the power supply 300 to be supplied to the controller 110. However, as can be appreciated, the electrical contacts 112a, 112b can be positioned and configured in other ways suitable for engaging with the terminals of the power supply 300 so that various embodiments of the power supply can be used. For example, in another embodiment, both electrical contacts can be positioned on either the top or bottom of the power supply and configured to engage either the top or bottom of the power supply.
[0072] In some embodiments, the power supply 300 may further comprise a protection circuit. Such a protection circuit may prevent overcharging of the power supply and / or regulate the release of current within an acceptable range. Additionally, the power supply may, in some embodiments, further include a shock-absorbing member (e.g., a foam pad) that may protect the power supply from damage associated with dropping the aerosol delivery device 100.
[0073] 2 and 3, in some embodiments, the power supply cavity 104 and the cartridge cavity 106 may be elongated and may establish longitudinal axes 104a, 106a, respectively. The longitudinal axes 104a, 106a of the power supply cavity 104 and the cartridge cavity 106 may be substantially parallel to one another. Such a configuration allows for both the cartridge 200 and the power supply 300 to be received in a space-efficient manner within the housing 102.
[0074] As described herein, many existing embodiments of aerosol delivery devices establish a generally elongated tubular configuration, with the power source and cartridge generally positioned end-to-end to mimic smoking articles such as cigarettes and cigars. As a result, existing embodiments of aerosol delivery devices often include a cartridge and aerosol delivery device arranged such that their respective longitudinal axes are parallel to one another. However, as shown in Figures 2 and 3, the aerosol delivery device 100 of the present disclosure can be configured such that the longitudinal axis 104a of the power source cavity 104 and the longitudinal axis 106a of the cartridge cavity 106 are non-coaxial.
[0075] Configuring the power source cavity 104 and the cartridge cavity 106 with parallel, but non-coaxial, longitudinal axes 104a, 106a can provide a number of benefits. In this regard, the aerosol delivery device 100 can define a relatively short length due to the cartridge 200 and power source 300 being positioned side-by-side, rather than in an end-to-end relationship. Furthermore, configuring the power source cavity 104 and the cartridge cavity 106 side-by-side can allow the aerosol delivery device 100 to define an overall shape that is more suitable for transport within a user's pocket. Furthermore, this configuration can allow the aerosol delivery device 100 to fit more easily in a user's hand. In this regard, the relatively short length of the aerosol delivery device can make it easier for a user to carry and use the aerosol delivery device concealed in the palm of the user's hand, which may be desirable in certain social settings.
[0076] The side-by-side configuration may further provide a relatively large internal volume within the housing 102 suitable for receiving the components of the aerosol delivery device 100 in a number of different positions. In contrast, an aerosol delivery device arranged end-to-end limits options for component location because the reservoir within the cartridge and the power source within the control body typically establish a cylindrical configuration. This leaves the remaining space within the cartridge and control body typically annular or cylindrical, which is not suitable for receiving many components in a space-efficient manner. Furthermore, the relatively large internal volume of the aerosol delivery device 100 of the present disclosure provided by the housing 102 may accommodate a relatively large power source 300 and / or a relatively large cartridge 200, thus increasing their respective electrical capacitance and aerosol precursor composition storage capacity. Furthermore, the relatively large internal volume of the aerosol delivery device 100 may accommodate a variety of commercially available power sources rather than custom power sources that may be required for a cylindrical configuration, thereby reducing costs associated with the components of the aerosol delivery device.
[0077] The side-by-side configuration can also provide a relatively large external surface area. Furthermore, the side-by-side configuration can provide a relatively flat external surface (which may be slightly curved for ergonomic or aesthetic purposes) that may be more suitable for the display 116, as opposed to the sharply curved surfaces provided by cylindrical aerosol delivery devices. In this regard, commercially available electronic displays typically provide a flat display surface.
[0078] This allows, for example, the electronic display 116 to be positioned in many locations and to assume a relatively larger size than electronic displays on aerosol delivery devices that assume a cylindrical configuration. In the illustrated embodiment, the electronic display 116 is positioned at the top of the main body portion 102a of the housing 102. The external opening 108 that opens into the cartridge cavity 106 may also be positioned at the top of the main body portion 102a of the housing. This location of the electronic display 116 may allow a user to view the electronic display while the aerosol delivery device is held in the user's hand in a manner suitable for drawing on the cartridge 200. In this regard, the user's hand can hold the aerosol delivery device around the side so that the top surface of the aerosol delivery device, where the electronic display 116 and the exposed portion of the cartridge 200 are positioned, is exposed and not covered by the user's hand. Thus, various information regarding the aerosol delivery device 100 can be easily viewed during normal use. For example, data displayed by the electronic display 116 may include the amount of aerosol precursor composition remaining in the cartridge, the remaining power level, usage history information, thermal and aerosol emission settings, charging status, communication status (e.g., when connected to another device via Bluetooth or other communication protocol), time, and / or various other data.
[0079] The side-by-side configuration of the aerosol delivery device 100 of the present disclosure can provide additional advantages. For example, the cartridge 200 can engage the regulator 101 in a manner that provides a secure connection between the cartridge and regulator 101, thereby reducing stress and strain compared to embodiments of the aerosol delivery device in which the connection between the cartridge and regulator 101 is exposed (e.g., embodiments in which the cartridge and regulator are disposed end-to-end). In this regard, the coupler 114 can be recessed within or near the cartridge cavity 106 such that the housing 102 protects the connection between the cartridge 200 and regulator 101. Furthermore, because a portion, or more preferably a majority, of the longitudinal length of the cartridge 200 can be retained within the cartridge cavity 106, the size and shape of which can substantially match the size and shape of the cartridge, the housing 102 can resist movement of the cartridge, rather than the coupler 114 bearing the entirety of such stress and strain associated with forces applied to one or both of the cartridge and regulator 101. In this regard, in an aerosol delivery device in which the regulator and cartridge are arranged end-to-end, the connection between the cartridge and regulator can support all or substantially all of the stresses and strains associated with forces applied to one or both of the cartridge and regulator. Such stresses and strains can damage the connections therebetween and potentially interfere with their operation, including the electrical connections that supply current to the cartridge for vaporization. Furthermore, while “modern” devices may establish configurations other than the end-to-end configuration described above, such devices often include exposed electrical connectors that are subject to stresses and strains. Thus, the side-by-side, parallel, but non-coaxial, configuration of the power source cavity 104 and cartridge cavity 106 of the aerosol delivery device 100 of the present disclosure can provide various advantages.
[0080] Various embodiments of cartridge 200 may be used in aerosol delivery device 100. In this regard, in light of the various possible configurations of cartridge components, a side view of cartridge 200, rather than a cross-sectional view of cartridge 200, is shown in Figure 3. However, one example embodiment of a cartridge is shown in Figure 4.
[0081] 4 , cartridge 200′, according to an example embodiment of the present disclosure, may include base shipping plug 202′, base 204′, control component terminals 206′, electronic control component 208′, flow director 210′, sprayer 212′, reservoir base 214′, outer body 216′, label 218′, mouthpiece 220′, and mouthpiece shipping plug 222′. Base 204′ may be coupled to a first end of outer body 216′, and mouthpiece 220′ may be coupled to an opposing second end of the outer body to enclose at least a portion of the remaining components of cartridge 200′, except for label 218′, mouthpiece shipping plug 222′, and base shipping plug 202′. Base 204′ may be configured to engage coupler 114. In some embodiments, the base 204' may include anti-rotation features that substantially prevent relative rotation between the cartridge and an associated device, including a power source, as described in U.S. Patent Application Publication No. 2014 / 0261495 to Novak et al., the entire contents of which are incorporated herein by reference.
[0082] Base shipping plug 202' can be configured to engage with base 204' to protect base 204' prior to use of cartridge 200'. Similarly, mouthpiece shipping plug 222' can be configured to engage with mouthpiece 220' to protect mouthpiece 220' prior to use of cartridge 200'. Control component terminals 206', electronic control components 208', flow director 210', sprayer 212', and reservoir base 214' can be retained within outer body 216'. Label 218' at least partially surrounds outer body 216' and can include information thereon, such as a product identifier.
[0083] The nebulizer 212' may include first and second heating terminals 234a', 234b', a liquid transfer element 238', and a heating element 240'. In this regard, the reservoir base 214' may be configured to hold an aerosol precursor composition. The reservoir base 214' is in fluid communication with the liquid transfer element 238' to transfer the aerosol precursor composition from the reservoir base 214' to the heating element 240' (e.g., by capillary action). This allows the aerosol precursor composition to be vaporized when an electric current is directed to the heating element 240' via the heating terminals 234a', 234b'.
[0084] Various other details regarding components that may be included in cartridge 200' are described, for example, in U.S. Patent Application Publication No. 2014 / 0261495 to Novak et al., the entire contents of which are incorporated herein by reference.

[0085] In another embodiment, cartridge 200 may be substantially similar to or identical to the cartridge disclosed in U.S. Patent Application No. 14 / 286,552 to Brinkley et al., filed May 23, 2014, the entire contents of which are incorporated herein by reference. Thus, for example, the cartridge may include a flow director defining a non-tubular configuration, an electronics compartment sealed to a reservoir compartment, and / or any of the various other features and components disclosed herein. Therefore, it should be understood that the specific embodiments of cartridge 200 described herein are provided for illustrative purposes only.
[0086] In this regard, a cross-sectional view of a further embodiment of cartridge 200 is shown in FIG. 5. As shown, cartridge 200″, according to an example embodiment of the present disclosure, may include a base 204″, control component terminals 206″, electronic control component 208″, flow director 210″, which may be defined by an outer body 216″ or a separate component, sprayer 212″, and mouthpiece 220″. Sprayer 212″ may include first and second heating terminals 234a″ and 234b″, a liquid transfer element 238″, and a heating element 240″. Cartridge 200″ may further include a base shipping plug, a label, and a mouthpiece shipping plug, as described above.
[0087] Base 204'' may be coupled to a first end of outer body 216'' and mouthpiece 220'' may be coupled to an opposing second end of the outer body to enclose at least a portion of the remaining components of cartridge 200''. In some embodiments, base 204'' may include anti-rotation features that substantially prevent relative rotation between the cartridge and an associated device, including a power source, as disclosed in U.S. Patent Application Publication No. 2014 / 0261495 to Novak et al., the entire contents of which are incorporated herein by reference.
[0088] The cartridge 200'' may further include a sealing member 242'' and an initial liquid transfer element 244''. In this regard, the outer body 216'' and / or additional components may be configured to retain the aerosol precursor composition 246'' within the reservoir 248''. In some embodiments, the reservoir 248'' may be configured to be refillable, while in other embodiments, the cartridge 200'' may be configured for disposable use. The sealing member 242'' may include one or more apertures 250'' positioned at one end of the chamber 248'' that allow the aerosol precursor composition 246'' to contact the initial liquid transfer element 244''. Additionally, the liquid transfer element 238'' of the nebulizer 212'' may contact the initial liquid transfer element 244''. Both the initial liquid transfer element 244'' and the liquid transfer element 238'' of the sprayer 212'' may include wicking and / or porous materials that allow the aerosol precursor composition 246'' to move therethrough (e.g., via capillary action) so that when an electric current is applied to the heating element via heating terminals 234a'', 234b'' by the controller 110 of the control body 101, the aerosol precursor composition can be drawn into the heating element 240'', heated, and vaporized (see, e.g., Figure 6).
[0089] FIG. 6 shows the aerosol delivery device 100 when the power supply 300 is received in the power supply cavity 104 and the cartridge 200″ of FIG. 5 is received in the cartridge cavity 106. As shown, in some embodiments, the electrical circuitry may further include an illumination source 122, such as a light-emitting diode (LED). Additionally, the control body 101 may include an illumination source cover 124 that can cover, protect, and / or conceal the illumination source 122. The illumination source cover 124 may be translucent or transparent so that light emitted by the illumination source can pass through it. In some embodiments, the illumination source cover 124 may be a tinted or diffusing cover so that the presence of the illumination source is concealed or obscured when not in use.
[0090] As further shown in FIG. 6 , in some embodiments, cartridge 200″ can include a viewing window 252″ that allows a user to view the amount of aerosol precursor composition 246″ remaining in reservoir 248″. For example, all or a portion of outer body 216″ of cartridge 200″ can include a translucent or transparent material. Illumination source 122 and illumination source cover 124 can be positioned in body portion 102a of housing 102 at cartridge cavity 106 in alignment with viewing window 252″ such that light generated by the illumination source is directed into cartridge 200″ to facilitate viewing of the level of aerosol precursor composition 246″. In this regard, body portion 102a of housing 102 can include a notch or other feature that defines viewing opening 126. This allows a user to view the level of aerosol precursor composition 246″ through viewing opening 126.
[0091] Controller 110 can direct illumination source 122 to output light under certain circumstances, such as, for example, after a draw on cartridge 200'' is detected. Illumination source 122 can additionally or alternatively output light when a separate actuator (e.g., a button) is pressed or otherwise activated. Thus, the user can be kept informed of the level of aerosol precursor composition in cartridge 200''.
[0092] It should be noted that the inclusion of illumination source 122 is optional. In this regard, in some embodiments, ambient light may be sufficient to view the level of aerosol precursor composition 246'' through viewing opening 126. However, the inclusion of illumination source 122 may be preferred due to its improved usability in low light conditions.
[0093] The controller 110 may be configured to control one or more operations of the aerosol delivery device 100. The controller 110 may verify that the cartridge 200 is authentic using information provided by the control components 208′, 208″. Use of the cartridge 200 may be permitted only if the cartridge is determined to be authentic. Furthermore, when a user draws on the cartridge 200, the flow sensor 118 (e.g., a pressure sensor) may detect the draw. In response, the controller 110 directs current to the cartridge 200, which causes the heating elements 240′, 240″ to generate heat and vaporize the aerosol precursor composition, which may be directed toward the user. Furthermore, the aerosol delivery device may include an actuator that may be manually activated to trigger the controller to direct current to the cartridge 200. The actuator may be used in place of the flow sensor 118 or to provide auxiliary power from a power source to the cartridge to alter (e.g., increase) the aerosol emission of the aerosol delivery device. In other embodiments, the actuator can be used in conjunction with a controller to adjust the amount of power from the power source to the cartridge so that the aerosol delivery device can have various aerosol emission settings (e.g., aerosol mass emission settings). Thus, the actuator (e.g., a button or button assembly) can be configured to control the power output level directed from the power source to the cartridge.
[0094] In some embodiments, the actuator (e.g., a button or button assembly) can have a select region or multiple regions (e.g., a lower region, a middle region, and an upper region). Each region of the actuator can be configured to direct a different level of power (e.g., current and / or voltage) from the power source to the cartridge. This allows different regions of the actuator to correspond to different aerosol emission settings. The actuator can include one or more sensors (e.g., pressure sensors and / or force sensors) in each region so that force applied to the actuator by a user can be detected in one or more regions to control the emission of the aerosol through different selectable power output levels directed from the power source to the cartridge. Thus, the power output level can be controlled based on the position at which the actuator is actuated. Alternatively or additionally, the power output level can be controlled based on the amount of force applied to the actuator, which can be determined via a force sensor (e.g., a stress sensor or strain sensor).
[0095] As can be appreciated, the exact shape and dimensions of aerosol delivery device 100 can vary. In this regard, Figures 7-10 show alternative forms of regulator 101', and only the differences relative to regulator 101 described above will be discussed here. Thus, each of the aerosol delivery devices can include some or all of the components and features described herein in any combination, unless otherwise specified.
[0096] As shown in FIG. 7, the control 101′ may define a more rounded profile for improved ergonomics. As further shown in FIG. 7, the control 101′ may further include an indicator 128′. The indicator 128′ may output light to indicate the operational status of the control. In some embodiments, the indicator 128′ may be used to communicate the operational status of the device without using the electronic display surface 116′. For example, the indicator 128′ may flash or change color when the cartridge is low on aerosol precursor composition or to indicate that the power source needs recharging or replacement. Additionally, the indicator 128′ may illuminate when the flow sensor detects a breath on the cartridge.
[0097] In some embodiments, indicator 128′ may be configured to illuminate with one or more of a plurality of colors, durations, frequencies, and / or intensities to indicate to a user a particular status of the aerosol delivery device, such as, for example, the power output level, the status of the power source, and / or the operational or non-operational state of the aerosol delivery device corresponding to the output of the indicator. Accordingly, indicator 128′ may include an illumination source that operates with one or more of a plurality of colors, durations, frequencies, and / or intensities to indicate to a user a particular status of the aerosol delivery device, such as, for example, the power output level, the status of the power source, and / or the operational or non-operational state of the aerosol delivery device. Indicator 128′ may be configurable by a user to control the color(s) of the illumination source and / or other output parameters of the illumination source. Additionally, the user may control which device status values are communicated to the user by the illumination signal.
[0098] As further shown in FIG. 7 , the main body portion 102a' of the housing 102' can include a side opening 130'. The side opening 130' can be configured to engage an outer cover 132' (e.g., via an interference fit), as shown in FIG. 8 . This allows the outer cover 132' to engage with the outside of the housing 102'. In some embodiments, the outer cover 132' can include silicone to improve grip so that the control body 101' can be more easily held in the hand without dropping it. However, in other embodiments, various other materials (e.g., other rubbers) can be used, which can be textured or smooth. The use of a resilient outer cover 132' can provide various other advantages. For example, in one embodiment, pressing the outer cover 132' at the side opening 130' can activate the illumination source 122 (e.g., via activation of an actuator) to illuminate the fluid level within the cartridge 200. In another embodiment, the illumination source 122 can be activated by pressing the outer cover 132' at the side opening 130', and the duration of pressing the outer cover corresponds to the activation time of the illumination source, allowing the user to continuously illuminate the cartridge 200 for a desired period of time while filling or refilling the cartridge, or as otherwise desired for a user-selected period of time.
[0099] 9 is a partial side view of the control body 101′. As shown, the illumination source cover 124′ can be aligned with the viewing opening 126′, as described above. In this illustrated embodiment, the viewing opening 126′ can be relatively wide to facilitate viewing of the level of the aerosol precursor composition within the cartridge. For example, the viewing opening 126′ can, in some embodiments, define an opening having a width perpendicular to the longitudinal axis 106a′ of the cartridge cavity 106′ (equal to at least half the diameter of the cartridge).
[0100] As mentioned above, in some embodiments, the main body portion of the control housing may include multiple pieces. In this regard, FIG. 10 illustrates the first portion 102a1' of the main body portion 102a' of the housing 102' (see FIG. 7). The second portion 102a2' and the third portion 102a3' of the main body portion 102a' of the housing 102' are shown in FIG. 7. The third portion 102a3' may be integral with the portion 102a2' or may be a separate component. The first and second portions 102a1', 102a2' of the main body portion 102' of the housing 102' may be configured to engage with the opening and closing door 102b' (see FIG. 10). The electronic display 116' may be positioned in (e.g., below) the third portion 102a3' of the main body portion 102a' of the housing 102'. In this regard, in some embodiments, all or a portion of the housing 102' may be translucent or transparent. The housing 102' may further include or have an illumination source nearby. For example, the housing 102' may include the illumination source 122 described above, which may be configured to emit direct or indirect illumination through the housing 102', which may be translucent or transparent.
[0101] As shown in FIG. 10, the first portion 102a1′ of the body portion 102a′ of the housing 102′ may further include a side opening 134′ configured to engage the outer cover 132′ (see, for example, FIG. 8 ). This allows the outer cover 132′ to be securely held in place via the opposing side openings 130′, 134′. While the outer body 132′ may provide improved grip, the third portion 102a′ may include a metal such as aluminum for increased strength and / or improved appearance, or a separate outer body establishing such properties may be attached to the third portion.
[0102] 10 further illustrates the inside of first portion 102a1' of body portion 102a' of housing 102'. As shown, housing 102' may form one or more ribs 136' that may be configured to retain power source 300 (see, e.g., FIG. 3) within power source cavity 104' and / or retain cartridge 200 (see, e.g., FIG. 3) within cartridge cavity 106'. In this regard, ribs 136' may be curved or otherwise tailored to conform to the size and shape of power source 300 and / or cartridge 200. Ribs 136' may extend to ends 138'. Ends 138' of ribs 136' in first portion 102a1' of body portion 102a' of housing 102' can be configured to engage corresponding ends of ribs (see FIG. 7) in second portion 102a2' of body portion 102a' of housing 102' to separate power source cavity 104' from cartridge cavity 106' and retain power source 300 and cartridge 200 (see FIG. 3), respectively. In this regard, ends 138' of ribs 136' can together define partition wall 107' that is segmented along its length. The use of ribs 136', rather than a solid structure, can reduce the amount of material required to form housing 102', thereby reducing the weight and providing rigidity to the housing while also retaining components of control body 101' in desired positions. Ribs 136' may comprise a non-rigid material such as a foam or a thermoplastic polymer, or may include elements that include foam, thermoplastic polymer, or other non-rigid material that allows ribs 136' to compress or displace when power source 300 changes diameter, such as may occur with diametric expansion common to lithium-type batteries. In this regard, ribs 136' may at least partially surround power source 300 (see, e.g., FIG. 3).
[0103] 10, the first portion 102a1' of the body portion 102a' of the housing 102' may include protrusions and / or receptacles 140' that may be configured to engage corresponding receptacles / protrusions on the second portion 102a2' (see FIG. 7), thereby enabling the portions 102a1', 102a2' of the housing 102' to be coupled to one another when assembled.
[0104] As shown in FIG. 10 , portion 102b′ may include an orifice 137′ or multiple orifices in fluid communication between power supply cavity 104′ and the atmosphere outside housing 102′ to allow any gas(es) that may be generated by power supply 300 (e.g., see FIG. 3 ) to escape, thereby preventing the gas(es) from creating a region of increased pressure within housing 102′. Orifice 137′ may comprise one or more openings having a cross-sectional area sufficient to prevent a pressure differential between the interior region of housing 102′ and the external atmosphere. In one embodiment, orifice 137′ may include a permeable membrane or porous material that allows gas(es) that may be generated by power supply 300 (e.g., see FIG. 3 ) to escape to the external atmosphere while simultaneously preventing liquid from entering housing 102′ due to the selective permeability of the membrane or porous material.
[0105] 11-15 illustrate a further embodiment of a control body 101″. The control body 101″ may be substantially similar in one or more respects to the control body 101′ of FIGS. 7-10. In this regard, as shown in FIGS. 11 and 12, the control body 101″ may include a housing 102″ comprising a main body portion 102a″ and an opening / closing door 102b″ that may be secured to the main body portion by screws 120″ (see FIG. 13). The main body portion 102a″ may include multiple portions, including first and second portions 102a1″, 102a2″. The first portion 102a1″ may define a protrusion and / or receptacle 140″ configured to engage a corresponding receptacle / protrusion in the second portion 102a2′ (see FIG. 7). The body portion 102a'' may define one or more ribs 136'' that each extend to an end 138'' to define a septum 107''. As shown, in some embodiments, the ribs 136'' may extend into both the power source cavity 104'' and the cartridge cavity 106'', thereby assisting in retaining the power source and cartridge therein, respectively. Additionally, the control body 101'' may include an indicator 128'' and an outer cover 132'' (see FIG. 14). An electronic display 116'' may be positioned at the top of the housing 102'' proximate to an opening to an exterior opening 108'' that opens into the cartridge cavity 106'' extending along the longitudinal axis 106a''.
[0106] However, the control body 101'' may differ in one or more respects from the control bodies described above. In this regard, in addition to the ends 138'' of the ribs 136'', the septum 107'' may further include a partial wall 109'' that further assists in retaining the cartridge within the cartridge cavity 106''. Furthermore, as shown in FIGS. 11 and 12, in some embodiments, the body portion 102a'' of the housing 102'' may include first and second partial side openings 130a'', 130b'' in a first portion 102a1'' and first and second side openings 134a'', 134b'' in a second portion 102a2'' thereof (see FIGS. 11 and 13). As shown in FIG. 12, the use of multiple side openings 130a'', 130b'', 134a'', 134b'' in each portion 102a1'', 102a2'' of the main body portion 102a'' of the housing 102'' can improve engagement therewith with the outer cover 132''.
[0107] Further, as shown in FIG. 15 and as described above, in some embodiments, the viewing opening 126′ may be relatively wide (see, e.g., FIG. 9). However, as shown in FIG. 13, in other embodiments, the viewing opening 126″ may be relatively narrow. For example, in some embodiments, the viewing opening may define a width that is less than or equal to half the diameter configured to be received within the cartridge compartment 106″. A wide viewing opening may provide better visibility of the aerosol precursor composition level, while a relatively narrow viewing opening may provide better protection for the cartridge while still allowing the user to view the aerosol precursor composition level.
[0108] In a further embodiment, FIG. 16 illustrates a method of assembling an aerosol delivery device. As illustrated, the method may include providing a housing in operation 402. The housing may define a power source cavity configured to receive a power source and a cartridge cavity configured to receive a cartridge containing an aerosol precursor composition. The power source cavity and the cartridge cavity may be elongated and each establish a longitudinal axis. The longitudinal axes of the power source cavity and the cartridge cavity may be non-coaxial and oriented substantially parallel to one another. Further, the method may include positioning electrical contacts within the power source cavity in operation 404, the electrical contacts configured to engage the power source. Further, the method may include positioning a coupler within the cartridge cavity, the coupler configured to engage the cartridge, in operation 406.
[0109] In some embodiments, the method may further include inserting a power source into the power source cavity and engaging the power source with the electrical contacts. The method may further include inserting a cartridge into the cartridge cavity and engaging the cartridge with the coupler. Inserting the cartridge into the cartridge cavity may include inserting the cartridge through an exterior opening defined by the housing.
[0110] The step of providing a housing in operation 402 may include defining a viewing opening in the cartridge cavity. Further, the method may include engaging an outer cover with the exterior of the housing. The method may further include positioning an illumination source within the housing. The illumination source may be configured to illuminate the cartridge within the cartridge cavity. The method may further include engaging an electronic display with the housing. The step of providing a housing in operation 402 may include engaging a first body portion with a second body portion. The step of providing a housing in operation 402 may further include engaging an opening / closing door with at least one of the first body portion and the second body portion, the opening / closing door configured to selectively provide access to the power supply cavity.
[0111] A further embodiment of an aerosol delivery device 500 is shown in Figure 17. As shown, the aerosol delivery device 500 can include a regulator 501 and a cartridge. In the illustrated embodiment, the cartridge 200'' of Figure 5 is included in the aerosol delivery device 500. However, in other embodiments, it will be appreciated that other cartridges may be used.
[0112] The control body 501 may include a housing 502. The housing 502 may be a unitary component or may comprise multiple pieces. For example, the housing 502 may include a power supply portion 502a, a door 502b, and a coupler portion 502c. The door 502b may include an orifice or orifices that are in fluid communication with the atmosphere outside the housing 502b, as described above with respect to orifice 137 in FIG. 10, to allow any gas(es) that may be generated by the power supply 504 (see FIG. 18) to escape, thereby preventing the gas(es) from creating a region of increased pressure within the housing 502. In this regard, each of the housings of the aerosol delivery device of the present disclosure may include such an orifice. The orifice is preferably located on the door to conceal the orifice and to position the orifice in the power supply cavity, although in other embodiments, the orifice may be positioned elsewhere.
[0113] In this regard, FIG. 18 illustrates a partial exploded view of control body 501. As illustrated, power supply portion 502a of housing 502 may include a first body portion 502a1 and a second body portion 502a2. First body portion 502a1 and second body portion 502a2 may be configured to engage with one another to define power supply cavity 504. Power supply cavity 504 may be configured to receive power source 600 (e.g., a battery and / or a capacitor). Power supply cavity 504 may define a first longitudinal axis 504a.
[0114] Additionally, coupler portion 502c of housing 502 can be configured to engage power supply portion 502a of the housing. Coupler 514 can be engaged with coupler portion 502c of housing 502. For example, coupler 514 can be at least partially positioned within coupler portion 502c of housing 502.
[0115] The coupler 514 can be configured to engage a cartridge 200″ (see FIG. 17 ), which can contain an aerosol precursor composition. As shown in FIG. 17 , the cartridge 200″ can extend along a second longitudinal axis 200 a″ when engaged with the coupler 514. The first longitudinal axis 504 a defined by the power source cavity 504 and the second longitudinal axis 200 a″ established by the cartridge 200″ can be non-coaxial and oriented substantially parallel to one another. This configuration can provide various advantages, as discussed above with respect to regulator embodiments in which the longitudinal axes of the power source cavity and the cartridge cavity are non-coaxial but substantially parallel.
[0116] In some embodiments, the cartridge 200'' may be at least partially received within the coupler cavity 506 defined by the coupler portion 502c of the housing 502. In this regard, as described above, the coupler 514 may be at least partially received within the coupler cavity 506. Thus, the depth of the coupler cavity 506 and the position of the coupler 514 therein (see FIG. 18 ) may determine whether the cartridge 200'' is at least partially received within the coupler cavity 506. Partially receiving the cartridge 200'' within the coupler cavity 506 may improve engagement between the cartridge and the control body 501 and / or reduce susceptibility of the coupler 514 to damage or contamination. However, in other embodiments, the cartridge 200'' may not extend within the coupler portion 502c of the housing 502. This configuration may facilitate engagement between the cartridge 200'' and the coupler 514, allowing a wider range of shapes and sizes of cartridges to be used with the control body 501.
[0117] The control entity 501 may further include a controller 510 (see, e.g., FIG. 20), which is not shown in FIG. 18 for clarity. The controller 510 may comprise a control board in some embodiments. The controller 510 may be configured to control some or all of the functions of the control entity 501, including directing current from the power supply 600 to the cartridge 200″. In this regard, the controller 510 may be electrically coupled to the power supply 600.
[0118] As shown in FIG. 18 , the control body 501 may further include one or more button assemblies. In particular, the control body 501 may include a first button assembly 542 and a second button assembly 544. As shown in FIG. 19 , the first button assembly 542 may be configured to activate a first switch 546 on the controller 510. Similarly, the second button assembly 544 may be configured to activate a second switch 548 on the controller 510. In this regard, the button assemblies 542, 544 may be configured to flex or otherwise move to activate the switches 546, 548. By way of example, the first button assembly 542 and the second button assembly 544 may be hingedly coupled to one or both of the first body portion 502a1 and the second body portion 502a2 of the power supply portion 502a of the housing 502 (see, e.g., FIG. 18 ).
[0119] As such, actuation of switches 546, 548 can control one or more functions of controller 501. For example, actuation of first switch 546 can direct current from power source 600 to cartridge 200'' (see FIG. 17) to heat the aerosol precursor composition within cartridge 200'' and generate an aerosol. Additionally, actuation of second switch 548 can control other functions.
[0120] By way of example, the control body 501 may further include an illumination source 522, such as a light-emitting diode (LED). The illumination source 522 may be configured to output illumination. In this regard, the control body 501 may include an illumination source cover 524 that may cover, protect, and / or conceal the illumination source 522. The illumination source cover 524 may be translucent or transparent so that light emitted by the illumination source can pass therethrough. In some embodiments, the illumination source cover 524 may be a tinted or diffusing cover so that the presence of the illumination source 522 is concealed or obscured when not in use.
[0121] Illumination source 522 may be configured to illuminate cartridge 200″. In particular, as shown schematically in FIG. 17 , cartridge 200″ may include a viewing window 252″, as described above, to allow a user to view the level of aerosol precursor composition within cartridge 200″. Accordingly, second button assembly 544 may be used to turn on illumination source 522 so that illumination is directed through viewing window 252″ of cartridge 200″, thereby allowing a user to more easily view the level of aerosol precursor composition within cartridge 200″, and / or the second switch may perform other functions. For example, in another embodiment, activating second switch 548 by pressing second button assembly 544 may cause controller 510 to provide auxiliary power from the power source to the cartridge to increase aerosol emission of the aerosol delivery device or to direct power to the cartridge regardless of whether a draw on the cartridge is detected. In this regard, in some embodiments, the aerosol delivery device may not include a flow sensor. In other embodiments, the second button assembly 544 may be used to activate the second switch 548 to cycle through various adjustable controller power output levels so that the device can have various aerosol mass emission settings, or various other functions can be controlled. Thus, any of the second button assembly 544 and / or other actuators described herein may be configured to control the power output level directed from the power source to the cartridge and / or otherwise control the amount (e.g., mass) of aerosol emitted.
[0122] In some embodiments, the second button assembly 544 may at least partially define a partition 550 that separates the cartridge 200'' from the power supply cavity 504 (see FIG. 18). Additionally, as described below, the controller 510 may be received within the power supply cavity 504. This allows the second button assembly 544 to include the illumination source cover 524 in the partition 550 such that illumination can be directed through the illumination source cover to the cartridge 200''.
[0123] Assembly of the control body 501 may be performed in a variety of ways. In one embodiment, the controller 510 may be at least partially wrapped around the power source 600, as shown in FIG. 20 . For example, the controller 510 may be bent or otherwise configured such that the power source 600 is received between opposing, substantially parallel walls of the controller. The controller 510 may then be electrically connected to the power source 600. In this regard, by way of example, the power source may include a wire or other conductor soldered or otherwise connected to the controller 510.
[0124] 21 , the controller 510 and power supply 600 can be inserted into the housing 502. More specifically, the controller 510 and power supply can be received in the power supply cavity 504. In some embodiments, the housing 500 can include features configured to engage the controller 510. For example, as shown, the controller 510 can be received in a slot 552 that can be defined by an extension 554 formed by the first body portion 502a1 of the power supply portion 502a of the housing 502. This allows the extension 554 to support the controller 510 and thereby actuate the switches 546, 548, as described above.
[0125] In one embodiment, the first button assembly 542 may be engaged with the first body portion 502a1 of the power supply portion 502a of the housing 502 before the controller 510 and power supply 600 are inserted into the power supply cavity 504. For example, a portion of the first button assembly 542 may be welded (e.g., ultrasonically welded), glued, fitted via an interference fit, or mechanically coupled to the first body portion 502a1 of the power supply portion 502a of the housing 502. This allows the first button assembly 542 to be engaged with the first body portion 502a1 but still be movable to actuate the first switch 546 as described above. Also, as further shown in FIG. 21 , in some embodiments, the second button assembly 544 may be engaged with the first body portion 502a1 of the power supply portion 502a of the housing 502 before the controller 510 and power supply 600 are inserted into the power supply cavity 504. For example, a portion of second button assembly 544 may be welded (e.g., ultrasonically welded), glued, fitted with an interference fit, or mechanically coupled to first body portion 502a1 of power supply portion 502a of housing 502. This allows second button assembly 544 to be engaged with first body portion 502a1 but still movable to actuate second switch 546 as described above.
[0126] Returning to FIG. 20 , controller 510 may include connector 556. Connector 556 may comprise an electrical connector and / or a data connector. Thus, connector 556 may be used to recharge power supply 600 and / or to send and receive data to and from controller 510. As shown in FIG. 21 , housing 502 may include a recess 558 configured to receive connector 556. For example, recess 558 may be defined by one or both of first body portion 502a1 and second body portion 502a2 of power supply portion 502a of housing 502.
[0127] 22 , the second body portion 502a2 of the power supply portion 502a of the housing 502 can be engaged with the first body portion 502a1 after the controller 510 and the power supply 600 are inserted into the power supply cavity 504. For example, the second body portion 502a2 can be welded (e.g., ultrasonically welded), glued, fitted with an interference fit, or mechanically coupled to the first body portion 502a1 of the power supply portion 502a of the housing 502. Also, the coupler portion 502c of the housing 502 can be engaged with the power supply portion 502a of the housing 502. For example, the coupler portion 502c can be welded (e.g., ultrasonically welded), glued, fitted with an interference fit, or mechanically coupled to the power supply portion 502a of the housing 502.
[0128] FIG. 22 further illustrates a coupler 514 engaged with the housing 502. In particular, the coupler 514 may be received within the coupler cavity 506. As shown in FIG. 23, additional components may be inserted within the coupler cavity 506. In particular, a seal 560 may be inserted through the coupler 514. Additionally, an electrical contact 562 may extend through the seal 560. The seal 560 may be configured to electrically insulate the coupler 514 from the electrical contact 562. In this regard, the electrical contact 562 may include a conductive material such as brass, and the seal 560 may include an electrically insulating material such as silicone. The electrical contact 562 may be engaged with a first terminal 564 (see, e.g., FIG. 22 ) of the controller 510. For example, the electrical contact 562 may be welded to the first terminal 564 after the first terminal 564 is bent into contact with the electrical contact 562.
[0129] Further, the tab 566 may be engaged with the coupler 514 and received within the coupler cavity 506 defined by the coupler portion 502c of the housing 502. A fastener 568 (e.g., a nut) may be secured to the coupler 514 to hold the tab 566 engaged with the coupler 514. The tab 566 may be coupled to a second terminal 570 (see, e.g., FIG. 22 ) of the controller 510. For example, the second terminal 570 may be welded to the tab 566 after the second terminal is bent and engaged with the tab 566. This may electrically couple the coupler 514 to the controller 510. In another embodiment, the second terminal 570 may directly engage the coupler 514. In any event, when the cartridge 200″ is engaged with the regulator 501 via the electrical contacts 562 and the coupler 514, positive and negative connections with the cartridge may be established (see FIG. 17 ). This allows current to be directed to cartridge 200'' to vaporize the aerosol precursor composition within the cartridge as directed by controller 510 when a user presses first button assembly 542 (see, e.g., FIG. 18).
[0130] After the various components described above are inserted into coupler cavity 506, opening and closing door 502b (see FIG. 18) can be engaged with power supply portion 502a and coupler portion 502c of housing 502. This allows control body 501 to define the completed configuration shown in FIG.
[0131] Although the controllers of the present disclosure are described herein as being usable with cartridges, it should be understood that the term "cartridge" is intended to include embodiments referred to as "tanks" or "tank-type cartridges." A tank may not include a reservoir substrate, may be at least partially transparent or translucent to allow viewing of the aerosol precursor composition level, and may be distinguishable from other embodiments of cartridges for aerosol delivery devices in that the tank may contain a relatively large amount of aerosol precursor composition. An embodiment of a tank-type cartridge is described in U.S. Patent Application No. 14 / 802,667 to O'Brien, filed July 17, 2015, the entire contents of which are incorporated herein by reference.
[0132] In a further embodiment, a method of assembling an aerosol delivery device is provided. As shown in FIG. 24 , the method may include, at operation 702, providing a housing defining a power source cavity configured to receive a power source, the power source cavity defining a first longitudinal axis. Further, the method may include, at operation 704, engaging a coupler configured to engage a cartridge containing an aerosol precursor composition with the housing such that the cartridge extends along a second longitudinal axis, the first longitudinal axis and the second longitudinal axis being non-coaxial and substantially parallel to one another. Further, the method may include, at operation 706, positioning a controller within the housing configured to engage the power source.
[0133] In some embodiments, the method may further include engaging a power source with the controller. Additionally, the method may include inserting the power source into the power source cavity simultaneously with positioning the controller within the housing at operation 706. Additionally, the method may include engaging a cartridge with the coupler. The cartridge may include a viewing window. The method may further include positioning an illumination source within the housing configured to direct illumination through the viewing window.
[0134] In some embodiments, providing a housing in Operation 702 may include engaging a first body portion with a second body portion. Providing a housing in Operation 702 may further include engaging a door with at least one of the first body portion and the second body portion, the door configured to block access to the power supply cavity. Providing a housing in Operation 702 may further include engaging a button assembly with at least one of the first body portion and the second body portion. Further, the method may include positioning an illumination source within the housing and engaging an illumination source cover with the button assembly, the illumination source cover configured to direct illumination generated by the illumination source therethrough.
