The present disclosure relates to aerosol delivery devices, and more particularly to an aerosol delivery device which may utilize electrical power to atomize an aerosol precursor composition for the production of an aerosol. In various embodiments, the aerosol precursor composition, which may incorporate materials and/or components that may be made or derived from tobacco or otherwise incorporate tobacco or other plants, may include natural or synthetic components including flavorants, and/or may include one or more medicinal components, is atomized to produce an inhalable substance for human consumption.
Many smoking devices have been proposed through the years as improvements upon, or alternatives to, smoking products that require combusting tobacco for use. Many of those devices purportedly have been designed to provide the sensations associated with cigarette, cigar, or pipe smoking, but without delivering considerable quantities of incomplete combustion and pyrolysis products that result from the burning of tobacco. To this end, there have been proposed numerous smoking products, flavor generators, and medicinal inhalers that utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar, or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat generating sources set forth in the background art described in U.S. Pat. No. 7,726,320 to Robinson et al., U.S. Pat. App. Pub. No. 2013/0255702 to Griffith Jr. et al., and U.S. Pat. App. Pub. No. 2014/0096781 to Sears et al., which are incorporated herein by reference in their entireties. See also, for example, the various types of smoking articles, aerosol delivery devices, and electrically powered sources referenced by brand name and commercial source in U.S. Pat. App. Pub. No. 2015/0216232 to Bless et al., which is incorporated herein by reference in its entirety. However, it would be desirable to provide an aerosol delivery device with enhanced functionality. In this regard, it is desirable to provide an aerosol delivery with advantageous features.

These and other features, aspects, and advantages of the disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below. The invention includes any combination of two, three, four, or more of the above-noted embodiments as well as combinations of any two, three, four, or more features or elements set forth in this disclosure, regardless of whether such features or elements are expressly combined in a particular embodiment description herein. This disclosure is intended to be read holistically such that any separable features or elements of the disclosed invention, in any of its various aspects or embodiments, should be viewed as combinable unless the context clearly dictates otherwise.
In order to assist the understanding of aspects of the disclosure, reference will now be made to the appended drawings, which are not necessarily drawn to scale and in which like reference numerals refer to like elements. The drawings are provided by way of example to assist understanding of aspects of the disclosure, and should not be construed as limiting the disclosure.
The present disclosure will now be described more fully hereinafter with reference to example embodiments thereof. These example 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, the 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 the specification and the appended claims, the singular forms “a,” “an,” “the” and the like include plural referents unless the context clearly dictates otherwise. Also, while reference may be made herein to quantitative measures, values, geometric relationships or the like, unless otherwise stated, any one or more if not all of these may be absolute or approximate to account for acceptable variations that may occur, such as those due to engineering tolerances or the like. As used herein, “substantially free” refers to concentrations of a given substance of less than 1% by weight or less than 0.5% by weight or less than 0.1% by weight based on total weight of a material.
As described hereinafter, embodiments of the present disclosure relate to aerosol delivery devices or vaporization devices, said terms being used herein interchangeably. Aerosol delivery devices according to the present disclosure use electrical energy to vaporize a material (preferably without combusting the material to any significant degree and/or without significant chemical alteration of the material) to form an inhalable substance; and components of such devices have the form of articles that most preferably are sufficiently compact to be considered hand-held devices. That is, use of components of some aerosol delivery devices does not result in the production of smoke—i.e., from by-products of combustion or pyrolysis of tobacco, but rather, use of those preferred systems results in the production of vapors resulting from vaporization of an aerosol precursor composition. In some examples, components of aerosol delivery devices may be characterized as electronic cigarettes, and those electronic cigarettes most preferably incorporate tobacco and/or components derived from tobacco, and hence deliver tobacco derived components in aerosol form. Other examples include delivery devices for cannabinoids, such as Tetrahydrocannabinol (THC) and/or Cannabidiol (CBD), botanicals, medicinals, nutraceuticals, and/or other active ingredients.
Aerosol generating devices of certain preferred aerosol delivery devices may provide many of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe that is employed by lighting and burning tobacco (and hence inhaling tobacco smoke), without any substantial degree of combustion of any component thereof. For example, the user of an aerosol generating device of the present disclosure can hold and use the device much like a smoker employs a traditional type of smoking article, draw on one end of that device for inhalation of aerosol produced by that device, take or draw puffs at selected intervals of time, and the like.
Aerosol delivery devices of the present disclosure also may be characterized as being vapor-producing articles or medicament delivery articles. Thus, such articles or devices may be adapted so as to provide one or more substances (e.g., flavors and/or pharmaceutical active ingredients) in an inhalable form or state. For example, inhalable substances may be substantially in the form of a vapor (i.e., a substance that is in the gas phase at a temperature lower than its critical point). Alternatively, inhalable substances may be in the form of an aerosol (i.e., a suspension of fine solid particles or liquid droplets in a gas). For purposes of simplicity, the term “aerosol” as used herein is meant to include vapors, gases, and aerosols of a form or type suitable for human inhalation, whether or not visible, and whether or not of a form that might be considered to be smoke-like.
Aerosol delivery devices of the present disclosure most preferably comprise some combination of a power source (i.e., an electrical power source), at least one control component (e.g., means for actuating, controlling, regulating and ceasing power for heat generation, such as by controlling electrical current flow the power source to other components of the article—e.g., processing circuitry, such as may comprise a microcontroller or microprocessor), an atomization assembly (e.g., means for aerosolizing a liquid composition, such as may comprise one or more pumps, optionally configured to provide varying flow characteristics, and an atomization nozzle), a reservoir configured to contain a liquid composition (e.g., commonly an aerosol precursor composition liquid capable of yielding an aerosol, such as ingredients commonly referred to as “smoke juice,” “e-liquid” and “e-juice”), and a mouthpiece or mouth region for allowing draw upon the aerosol delivery device for aerosol inhalation (e.g., a defined airflow path through the article such that aerosol generated may be withdrawn therefrom upon draw).
Alignment of the components within the aerosol delivery device and/or the configuration of the device overall may be variable. For example, the aerosol delivery device may have a one-piece design (e.g., forming a singular body including all components of the device), a two-piece design (e.g., having two detachable sections), a three-piece design (e.g., having three detachable sections), or more. Typically, the components within each individual section and/or the arrangement of those components within each individual section may vary. In some embodiments, for example, various sections of the device and/or components within those sections may be considered to removable, replaceable, or reusable. In specific embodiments, the aerosol precursor composition may be located between two opposing ends of the device (e.g., within a reservoir of a cartridge, which in certain circumstances is replaceable, disposable, reusable, and/or refillable). Other configurations, however, are not excluded. Generally, the components are configured relative to one another so that energy from the atomization assembly vaporizes the aerosol precursor composition (as well as one or more flavorants, medicaments, or the like that may likewise be provided for delivery to a user) and forms an aerosol for delivery to the user. When the atomization assembly vaporizes the aerosol precursor composition, an aerosol is formed, released, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the foregoing terms are meant to be interchangeable such that reference to release, releasing, releases, or released includes form or generate, forming or generating, forms or generates, and formed or generated. Specifically, an inhalable substance is released in the form of a vapor or aerosol or mixture thereof.
More specific formats, configurations and arrangements of components within the aerosol delivery devices of the present disclosure will be evident in light of the further disclosure provided hereinafter. Additionally, the selection and arrangement of various aerosol delivery device components may be appreciated upon consideration of the commercially available electronic aerosol delivery devices, such as those representative products referenced in the background art section of the present disclosure.

It should be noted that all pressure values referred to herein are intended to define a relative pressure output (e.g., the pressure relative to ambient pressure) rather than absolute pressure.
Suitable air pumps may include, but are not limited to, a micro-compressor pump, a micro-blower, a rotary micro-pump, a diaphragm micro-pump, and a piezoceramic micro-pump. In some embodiments, such as the embodiment depicted in
As noted above, the second pump 104 may be configured to deliver a flow of liquid at a second flow rate and pressurized at a second pressure range. In some embodiments, the second pump 104 may be in the form of a pressurized liquid pump. For example, the second pump may be configured to deliver the liquid composition to the nozzle at a flow rate in the range of about 0.1 mL/min to about 10 mL/min, or about 0.2 to about 5 mL/min, or about 0.5 to about 2 mL/min. In some embodiments, the second pump may be configured to deliver the liquid composition to the nozzle at a flow rate of about 10 mL/min or less, about 7.5 mL/min or less, about 5 mL/min or less, about 2.5 mL/min or less, or about 1 mL/min or less. In some embodiments, the liquid pump is configured to deliver the liquid composition at a pressure in the range of about 0.1 psi to about 10 psi, about 0.5 psi to about 5 psi, or about 1 psi to about 2.5 psi. in some embodiments, the liquid pump is configured to deliver the liquid composition at a pressure of about of about 10 psi or less, about 7.5 psi or less, about 5 psi or less, about 2.5 psi or less, or about 1 psi or less. Suitable liquid pumps may include, but are not limited to, a centrifugal micro-pump, a ring micro-pump, a rotary micro-pump, a diaphragm micro-pump, a peristaltic micro-pump, and a step micro-pump. In some embodiments, the second pump may be connected to the nozzle via a first liquid transport element 122 capable of transferring the pressurized flow of air from the first pump 102 to the nozzle 106. In some embodiments, the first liquid transport element may be in the form of a hollow tubing or casing capable of transporting a pressurized flow of liquid, for example. Various types of tubing and/or liquid transport elements may be suitable for use in aerosol delivery devices according to the present disclosure.
In some embodiments, the second pump 104 may be in fluid communication with the reservoir 110 and configured to transfer a flow of the liquid composition 112 from the reservoir 110 to the nozzle 106. In various embodiments, the reservoir 110 may be in fluid communication with (either directly or through one or more additional components, as noted above with respect to
Various types of reservoirs may also be suitable for use in embodiments of the present disclosure. In some embodiments, for example, the liquid reservoir may comprise an independent container (e.g., formed of walls substantially impermeable to the liquid composition), which, in some embodiments, may be configured to be removed, replaced, and/or refilled by a user of the device. In some embodiments, the reservoir may define a substantially self-contained portion or section of the aerosol delivery device, or the reservoir may be provided as a component within the housing of the aerosol delivery device or a portion of the aerosol delivery device (e.g., a control unit, and atomizing section, or a cartridge portion) as discussed further herein. For example, as noted above, the aerosol delivery device may have a one-piece design (e.g., including the reservoir within the housing of the device, or the reservoir being removably attachable to the one-piece device), a two-piece design (e.g., including a control unit and a cartridge portion, wherein the reservoir may be included as a component within either), or a three-piece design (e.g., including a control unit, an atomizing section, and a reservoir housing, e.g., where the reservoir is self-contained within the reservoir housing). It should be noted that the configuration of the reservoir is not intended to be limiting and generally the reservoir may be removed, replaced, and/or refilled by a user of the device irrespective of the configuration of the overall device.
As depicted in
Other example embodiments of reservoirs and transport elements useful in aerosol delivery devices according to the present disclosure may vary, and such reservoirs and/or transport elements can be incorporated into devices such as those described herein. In some embodiments, a microfluidic chip may be embedded in the reservoir 110, and the amount and/or mass of liquid composition delivered from the reservoir may be controlled by the second pump, such as one based on microelectromechanical systems (MEMS) technology. In some embodiments, the second pump may be directly connected to the reservoir and/or the nozzle, for example, such that liquid is pumped directly from the reservoir via the second pump to the nozzle, whereby use of one or more transport elements is not necessary. In some embodiments, the second pump may optionally be positioned within the reservoir such that the second pump and the reservoir form a single component within the cartridge. Examples of suitable micropumps for use in embodiments of the present disclosure can be found, for example in U.S. patent application Ser. No. 16/203,069, directed to Micropump for an Aerosol Delivery Device, filed on Nov. 28, 2018; as well as U.S. Pat. No. 10,285,451 to Bless, both of which are incorporated herein by reference in their entireties.
As noted above, the nozzle 106 may be positioned within the housing 114 of the aerosol delivery device and configured to receive the flow of air (from the first pump 102) and the flow of liquid (from the second pump 104) and output the liquid in an atomized form. In the depicted embodiment of
In further embodiments, the aerosol delivery device 100 may comprise a power source 130 and a control component 132. In some embodiments, the power source may be configured to provide sufficient power to operate both the first and second pumps and the control component at the same time. In some embodiments, for example, the power source may be configured to provide sufficient power to operate both the first pump and the second pump simultaneously while providing sufficient power to one or more flow controlling components configured to control the output flow rate from the first and second pumps. Examples of useful power sources include lithium-ion batteries that may be rechargeable, e.g., a rechargeable lithium-manganese dioxide battery. In particular, lithium polymer batteries can be used as such batteries can provide increased safety. Other types of batteries, e.g., N50-AAA CADNICA nickel-cadmium cells, may also be used. In some embodiments, the power source may comprise low wattage lithium-ion batteries, for example, having an energy capacity generally in the range of about 500 mAh to about 3000 mAh and a voltage in the range of about 3 V to about 5 V. Additionally, a power source may be sufficiently lightweight to not detract from a desirable smoking experience. Some examples of possible power supplies are described in U.S. Pat. No. 9,484,155 to Peckerar et al. and U.S. Patent Application Publication No. 2017/0112191 to Sur et al., filed Oct. 21, 2015, the disclosures of which are incorporated herein by reference in their respective entireties.

The processing circuitry may include a processor embodied in a variety of forms such as at least one processor core, microprocessor, coprocessor, controller, microcontroller or various other computing or processing devices including one or more integrated circuits such as, for example, an ASIC (application specific integrated circuit), an FPGA (field programmable gate array), some combination thereof, or the like. In some examples, the processing circuitry may include memory coupled to or integrated with the processor, and which may store data, computer program instructions executable by the processor, some combination thereof, or the like.
In some example embodiments, the control component may include one or more input/output peripherals, which may be coupled to or integrated with the processing circuitry. More particularly, the control component may include a communication interface to enable wireless communication with one or more networks, computing devices or other appropriately-enabled devices. Examples of suitable communication interfaces are disclosed in U.S. Pat. App. Pub. No. 2016/0261020 to Marion et al., the content of which is incorporated herein by reference. Another example of a suitable communication interface is the CC3200 single chip wireless microcontroller unit (MCU) from Texas Instruments. In some embodiments, for example, the aerosol delivery device may be configured to send information to an electronic device via Near Field Communication (NFC) or Bluetooth technology. Additional examples of suitable manners according to which the aerosol delivery device may be configured to wirelessly communicate are disclosed in U.S. Pat. App. Pub. No. 2016/0007651 to Ampolini et al., and U.S. Pat. App. Pub. No. 2016/0219933 to Henry, Jr. et al., each of which is incorporated herein by reference. For example, the aerosol delivery device also may communicate with a computer or other device acting as an input via wireless communication. In such embodiments, an APP or other computer program may be used in connection with a computer, mobile device, or other computing device to input control instructions to the aerosol delivery device, such control instructions including, for example, the ability to deliver a desired total particulate matter (TPM) provided per puff, vary the duration and/or strength of aerosol produced per puff, amount of nicotine delivered per puff, and/or one or more different puff characteristics. Such puff characteristics may be controllable by a user of the aerosol delivery device, for example, via programmable user settings. In some embodiments, for example, the pressurized flow of air exiting the first pump and/or the pressurized flow of liquid exiting the second pump may be controlled by the control component (based on one or both of exit flow rate and exit pressure) based on the desired puff characteristics to be delivered to a user. In embodiments where the aerosol delivery device is a puff-actuated device, for example, as discussed further herein, the one or both of the pressure value and the flow rate at which air and/or liquid is delivered to the nozzle from the pumps may be controlled based on user puff characteristics, e.g., the pressure value may vary proportionally to the duration and/or strength of puff, such as may be determined by the magnitude of pressure drop when a user draws on the device.
In some embodiments, the aerosol delivery device may comprise an input element 140 to allow a user to control one or more functions of the device (e.g., as described herein above) and or to provide for activation/deactivation of the sleeve. Any component or combination of components may be utilized as the input element for controlling the function of the aerosol delivery device. For example, one or more pushbuttons may be used as described in U.S. Pub. No. 2015/0245658 to Worm et al., which is incorporated herein by reference. Likewise, a touchscreen may be used as described in U.S. patent application Ser. No. 14/643,626, filed Mar. 10, 2015, to Sears et al., which is incorporated herein by reference. As a further example, components adapted for gesture recognition based on specified movements of the temperature regulating sleeve may be used as an input. See U.S. Pub. 2016/0158782 to Henry et al., which is incorporated herein by reference. Various other components are also contemplated, particularly those suitable for use with aerosol delivery devices, and such components may be incorporated into the present disclosure as discussed more fully herein.
In some embodiments, the aerosol delivery device may further comprise a mouthpiece portion 134 within the outer housing 114. For example, in some embodiments the nozzle 106 may be in fluid communication with the mouthpiece portion 134 such that the atomized liquid produced by the nozzle enters the mouthpiece portion. In some embodiments, the nozzle 106 may be positioned proximate to the mouthpiece portion 134 such that the output of atomized liquid from the nozzle is immediately transferred to the mouthpiece portion. For example, the atomized liquid may be whisked, aspirated, sprayed, or otherwise drawn away from the orifice 108 of the nozzle 106 and out an opening 136 in the mouthpiece portion 134 configured for egress of the atomized liquid therefrom. Other configurations of mouthpiece portions are intended to be contemplated based on this disclosure, for example, such that there is an additional chamber or tubular void between the nozzle and the mouthpiece portion, or a section to provide cooling, or further a section to provide additional flavorings. The mouthpiece portion 134 may be configured as a specifically shaped portion of the outer housing 114 and may be permanently attached thereto, in some embodiments. Alternatively, the mouthpiece portion 134 may be a detachable member that is removably and replaceably attachable to the outer housing 114.
As noted above, the reservoir 110 is configured to contain a liquid composition 112. In some embodiments, the liquid composition 112 may be in the form of an aerosol precursor composition. Suitable aerosol precursor compositions may include, but are not limited to, one or more of a polyhydric alcohol, nicotine, tobacco, a tobacco extract, a flavorant, and other active ingredients. Example aerosol forming materials include polyhydric alcohols (e.g., glycerin, propylene glycol, and triethylene glycol) and/or water, and any other materials which yield a visible aerosol, as well as any combinations thereof.

No. WO 2014/182736 to Bowen et al., and U.S. Pat. No. 8,881,737 to Collett et al., the disclosures of which are incorporated herein by reference.
As noted above, in some embodiments the aerosol precursor composition comprises a glycerol-based liquid. In other embodiments, however, the aerosol precursor composition may be a water-based liquid. Such water-based liquids may be referred to as “water-based aerosol precursor compositions,” “aerosol precursor compositions,” and/or “water-based liquids” and generally include any ingredients discussed herein above in reference to aerosol precursor compositions. In some embodiments, the aerosol precursor composition may be comprised of more than approximately 60% water. For example, in some embodiments about 60% or greater water by weight, or about 65% or greater water by weight, or about 70% or greater water by weight, or about 75% or greater water by weight, or about 80% or greater water by weight, or about 85% or greater water by weight, or about 90% or greater water by weight, based on the total weight of the water-based aerosol precursor composition. In some embodiments, the water-based liquid may include up to approximately 10% propylene glycol. For example, in some embodiments the percentage of propylene glycol in the water-based liquid may be in the inclusive range of approximately 4% to approximately 5%. In some embodiments, the water-based liquid may include up to approximately 10% flavorant. For example, in some embodiments the percentage of flavorant(s) of the water-based liquid may be in the inclusive range of approximately 3% to approximately 7%. In some implementations, the water-based liquid may include up to approximately 1% nicotine. For example, in some embodiments the percentage nicotine in the water-based liquid may be in the inclusive range of approximately 0.1% to approximately 0.3%. In some embodiments, the water-based liquid may include up to approximately 10% cyclodextrin. For example, in some embodiments the percentage cyclodextrin in the water-based liquid may be in the inclusive range of approximately 3% to 5%. In still other embodiments, the aerosol precursor composition may be a combination of a glycerol-based liquid and a water-based liquid. For example, some embodiments may include up to approximately 50% water and less than approximately 20% glycerol. The remaining components may include one or more of propylene glycol, flavorants, nicotine, cyclodextrin, etc. Some examples of water-based liquid compositions that may be suitable are disclosed in GB 1817863.2, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817864.0, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817867.3, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817865.7, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817859.0, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817866.5, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817861.6, filed Nov. 1, 2018, titled Gel and Crystalline Powder; GB 1817862.4, filed Nov. 1, 2018, titled Aerosolisable Formulation; GB 1817868.1, filed Nov. 1, 2018, titled Aerosolised Formulation; and GB 1817860.8, filed Nov. 1, 2018, titled Aerosolised Formulation, each of which is incorporated by reference herein in its entirety.
As noted above, in various embodiments the liquid composition 112 may also include a flavorant. In some embodiments, the flavorant may be pre-mixed with the liquid. In other embodiments, the flavorant may be delivered separately downstream from the nozzle as a main or secondary flavor. Still other embodiments may combine a pre-mixed flavorant with a downstream flavorant. As used herein, reference to a “flavorant” refers to compounds or components that can be aerosolized and delivered to a user and which impart a sensory experience in terms of taste and/or aroma. Example flavorants include, but are not limited to, vanillin, ethyl vanillin, cream, tea, coffee, fruit (e.g., apple, cherry, strawberry, peach and citrus flavors, including lime, lemon, mango, and other citrus flavors), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, clove, lavender, cardamom, ginger, honey, anise, sage, rosemary, hibiscus, rose hip, yerba mate, guayusa, honeybush, rooibos, amaretto, mojito, yerba santa, ginseng, chamomile, turmeric, bacopa monniera, gingko biloba, withania somnifera, cinnamon, sandalwood, jasmine, cascarilla, cocoa, licorice, terpenes, trigeminal sensates and flavorings and flavor packages of the type and character traditionally used for the flavoring of cigarette, cigar, and pipe tobaccos. Other examples include flavorants derived from, or simulating, burley, oriental tobacco, flue cured tobacco, etc. Syrups, such as high fructose corn syrup, also can be employed. Example plant-derived compositions that may be suitable are disclosed in U.S. Pat. No. 9,107,453 and U.S. Pat. App. Pub. No. 2012/0152265 both to Dube et al., the disclosures of which are incorporated herein by reference in their entireties. The selection of such further components are variable based upon factors such as the sensory characteristics that are desired for the smoking article, and the present disclosure is intended to encompass any such further components that are readily apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See, e.g., Gutcho, Tobacco Flavoring Substances and Methods, Noyes Data Corp. (1972) and Leffingwell et al., Tobacco Flavoring for Smoking Products (1972), the disclosures of which are incorporated herein by reference in their entireties. It should be noted that reference to a flavorant should not be limited to any single flavorant as described above, and may, in fact, represent a combination of one or more flavorants.
As noted above, in some embodiments the aerosol delivery device may have a multi-piece design, such as a two-piece design (e.g., as depicted in
