The present disclosure relates to heat-not-burn (HNB) aerosol-generating devices and capsules configured to generate an aerosol without involving a substantial pyrolysis of an aerosol-forming substrate.
Some electronic devices are configured to heat a plant material to a temperature that is sufficient to release constituents of the plant material while keeping the temperature below a combustion point of the plant material so as to avoid any substantial pyrolysis of the plant material. Such devices may be referred to as aerosol-generating devices (e.g., heat-not-burn aerosol-generating devices), and the plant material heated may be tobacco and/or Cannabis. In some instances, the plant material may be introduced directly into a heating chamber of an aerosol-generating device. In other instances, the plant material may be pre-packaged in individual containers to facilitate insertion and removal from an aerosol-generating device.
At least some example embodiments relate to a heat-not-burn aerosol-generating device.
In at least one example embodiment, the heat-not-burn aerosol-generating device may include a housing that defines a capsule-receiving cavity and a lid fixedly coupled to the housing at a first point and releasably coupleable to the housing at a second point that is different from the first point. The lid may be configured to cover the capsule-receiving cavity in a closed position. The lid may include a first retainer and a replaceable mouthpiece coupleable to the lid such that air entering the housing and drawn through the capsule-receiving cavity exits out of the replaceable mouthpiece. The mouthpiece may include a second retainer that is configured to engage with the first retainer so as to releasably secure the replaceable mouthpiece to the lid.
In at least one example embodiment, the first retainer may include a retention bar and the second retainer may include a clip that defines a notch therein. The notch may be configured to receive the retention bar.

The various features and advantages of the non-limiting embodiments herein may become more apparent upon review of the detailed description in conjunction with the accompanying drawings. The accompanying drawings are merely provided for illustrative purposes and should not be interpreted to limit the scope of the claims. The accompanying drawings are not to be considered as drawn to scale unless explicitly noted. For purposes of clarity, various dimensions of the drawings may have been exaggerated.
Some detailed example embodiments are disclosed herein. However, specific structural and functional details disclosed herein are merely representative for purposes of describing example embodiments. Example embodiments may, however, be embodied in many alternate forms and should not be construed as limited to only the example embodiments set forth herein.
Accordingly, while example embodiments are capable of various modifications and alternative forms, example embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments to the particular forms disclosed, but to the contrary, example embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of example embodiments. Like numbers refer to like elements throughout the description of the figures.
It should be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “covering” another element or layer, it may be directly on, connected to, coupled to, or covering the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout the specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It should be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, regions, layers and/or sections, these elements, regions, layers, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section discussed below could be termed a second element, region, layer, or section without departing from the teachings of example embodiments.
Spatially relative terms (e.g., “beneath,” “below,” “lower,” “above,” “upper,” and the like) may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It should be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing various example embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” specify the presence of stated features, integers, steps, operations, and/or elements, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and/or groups thereof.
When the terms “about” or “substantially” are used in this specification in connection with a numerical value, it is intended that the associated numerical value includes a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical value. Moreover, when the terms “generally” or “substantially” are used in connection with geometric shapes, it is intended that precision of the geometric shape is not required but that latitude for the shape is within the scope of the disclosure. Furthermore, regardless of whether numerical values or shapes are modified as “about,” “generally,” or “substantially,” it will be understood that these values and shapes should be construed as including a manufacturing or operational tolerance (e.g., ±10%) around the stated numerical values or shapes.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
As used herein, “coupled” includes both removably coupled and permanently coupled. For example, when an elastic layer and a support layer are removably coupled to one another, the elastic layer and the support layer can be separated upon the application of sufficient force.
As illustrated, in at least one example embodiment, the aerosol-generating device 100 has a general oval or oblong or pebble shape and a replaceable mouthpiece 190 that extends from the main body of the aerosol-generating device 100. For example, the aerosol-generating device 100 may include a housing 120 that defines a capsule-receiving cavity 130 (as best shown in
An exterior of the housing 120 and/or lid 110 may be formed from a metal (such as aluminum, stainless steel, and the like); an aesthetic, food contact rated plastic (such as, a polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystalline polymer (LCP), a copolyester plastic, or any other suitable polymer and/or plastic); or any combination thereof. The replaceable mouthpiece 190 may be similarly formed from a metal (such as aluminum, stainless steel, and the like); an aesthetic, food contact rated plastic (such as, a polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystalline polymer (LCP), a copolyester plastic, or any other suitable polymer and/or plastic); and/or plant-based materials (such as wood, bamboo, and the like). One or more interior surfaces of the housing 120 and/or lid 110 may be formed from or coated with a high temperature plastic (such as, polyetheretherketone (PEEK), liquid crystal polymer (LCP), or the like). The lid 110 and the housing 120 may be collectively regarded as the main body of the aerosol-generating device 100.
The lid 110 may be fixedly coupled to the housing 120 at the first point 122 by a hinge 112, or other similar connector, that allows the lid 110 to move (e.g., swing and rotate) from an open position (such as illustrated in
The lid 110 may be releasably coupleable to the housing 120 at the second point 124 by a latch 114, or other similar connector, that allows the lid 110 to be fixed or secured in the closed position and easily releasable so as to allow the lid 110 to move from the secured closed position to the open position. In at least one example embodiment, the latch 114 may be coupled to a latch release mechanism 116. The latch release mechanism 116 may be configured to move the latch 114 from a first or closed position to a second or open position. For example, such as best illustrated in
In at least one example embodiment, such as best illustrated in
In at least one example embodiment, such as best illustrated in
In at least one example embodiment, the supply of current from the power source 150 may be in response to a manual operation (e.g., button-activation) or an automatic operation (e.g., puff-activation). The power source 150 may include one or more batteries (e.g., rechargeable dual battery arrangement, lithium-ion battery, and/or fuel cells). It should be understood that the shape of the battery (or batteries) for the power supply may vary. For example, the battery may be cylindrical, prismatic, disc-shaped, a pouch battery, or any other variation of battery shape known in the art. Additionally, it should be understood that the battery may be any of a variety of types. For example, in one embodiment, the battery may be a rechargeable battery (e.g., lithium-ion). In another embodiment, the battery may be a non-rechargeable battery (e.g., alkaline). In yet another embodiment, the battery may include silver oxide, carbon zinc, cadmium, nickel, or any another material known in the art. Furthermore, the battery may include a primary cell and/or a secondary cell. It will be understood by those of ordinary skill in the art that various changes in form and details of the battery may be made without departing from the spirit and the scope of the invention.
In at least one example embodiment, such as best illustrated in
In at least one example embodiment, the communication screen 140 is an integrated thin-film transistor (“TFT”) screen. In other example embodiments, the communication screen 140 is an organic light emitting diode (“OLED”) or light emitting diode (“LED”) screen. The communication screen 140 is configured for adult consumer engagement and may have a generally oblong shape.
In at least one example embodiment, the housing 120 defines a charging connector or port 170. For example, as best illustrated in
In at least one example embodiment, such as best illustrated in
The pores 173 in the protective grille 172 may function as inlets for air drawn into the aerosol-generating device 100. During the operation of the aerosol-generating device 100, ambient air entering through the pores 173 in the protective grille 172 around the charging connector 170 will converge to form a combined flow that then travels to the capsule 200. For example, the pores 173 may be in fluidic communication with the capsule-receiving cavity 130. In at least one example embodiment, air may be drawn from the pores 173 and through the capsule-receiving cavity 130. For example, air may be drawn through a capsule 200 received by the capsule-receiving cavity 130 and out of the replaceable mouthpiece 190.
The capsule 200 (for example, as illustrated in
As illustrated in
Referring to
In addition to the second opening 1322, the second end cap 1320 also defines an alignment recess 1326 and an inlet recess 1328. The alignment recess 1326 and the inlet recess 1328 may be viewed as being in a multi-level arrangement, where the base/inner end surface of the alignment recess 1326 (which exposes the first end section 1342 and the second end section 1346) may be regarded as being on one level, while the base/inner end surface of the inlet recess 1328 (or the grille-like surface of the second opening 1322) may be regarded as being on another level. The alignment recess 1326 is configured to facilitate a positioning of the capsule 1300 during its insertion into the device body of an aerosol-generating device. In at least one example embodiment, the alignment recess 1326 has angled sidewalls which taper inward toward the inlet recess 1328. With the angled sidewalls, the alignment recess 1326 may be quickly coupled with a corresponding engagement member of the device body with greater ease. For instance, when received within the capsule-receiving cavity 130 of the aerosol-generating device 100, the alignment recess 1326 of the capsule 1300 may be engaged with the angled surfaces 176 of the capsule connector 132, while the inlet recess 1328 of the capsule 1300 may be engaged with the capsule seal 202 (e.g.,

The above discussion should be understood to be a non-limiting introduction to the capsule 200, which, as noted supra, may be the same as the capsule 1300. As a result, the insertion and mechanical/electrical engagement of the capsule 200 within the aerosol-generating device 100 may be discussed with reference to the specific details of the capsule 1300. Further details and alternatives regarding the capsule 1300 are also subsequently discussed herein.
In at least one example embodiment, such as best illustrated in
In at least one example embodiment, the housing 120 encloses a capsule connector 132. Additionally, in some instances, the capsule connector 132 may be mounted or otherwise secured to a printed circuit board (PCB) within the housing 120. In at least one example embodiment, the capsule connector 132 defines the capsule-receiving cavity 130.
In at least one example embodiment, the capsule connector 132 includes a body or housing 134 that defines the capsule-receiving cavity 130. In at least one example embodiment, such as best illustrated in
In at least one example embodiments, the capsule connector 132 includes one or more electrical connectors or contacts 152A, 152B. For example, as illustrated, the capsule connector 132 may include a first electrical contact 152A and a second electrical contact 152B. As illustrated, the first electrical contact 152A may be in the form of three contact members. Similarly, the second electrical contact 152B may also be in the form of three contact members. The electrical contacts 152A, 152B are configured to apply current or other electrical signals to the capsule 200 received by the capsule-receiving cavity 130. In at least one example embodiment, the electrical contacts 152A, 152B may be in electrical communication with the power source 150 and/or control circuitry 160 disposed within the housing 120. The electrical contacts 152A, 152B can be formed of copper or of a copper alloy (e.g., copper-titanium), and in at least one example embodiment, the electrical contacts 152A, 152B may have a gold plating.
In at least one example embodiment, as best illustrated in
Similarly, the electrical contact 152B may include a combination of both the contact member 152′ and the contact member 152″. As illustrated, the electrical contact 152B may include a contact member 152″ between a pair of contact members 152′. In another instance, the electrical contact 152B may include a contact member 152′ between a pair of contact members 152″. Alternatively, instead of two types of contact members, the electrical contact 152B may include a plurality of one of the contact member 152′ or the contact member 152″ (e.g., identical contact members).
Each of the contact members 152′, 152″ includes a base 154A, 154B, respectively. In at least one example embodiment, each of the contact members 152′, 152″ has a terminal or soldering point 162A, 162B, respectively. As illustrated, the soldering point 162A of the contact member 152′ may be aligned (e.g., coaxial) with the base 154A. In contrast, the soldering point 162B of the contact member 152″ may be laterally shifted/offset relative to the base 154B so as to not be aligned with the base 154B while extending in parallel to the base 154B. As a result, an alternating arrangement of the contact members 152′, 152″ may provide a staggered positioning of the soldering points 162A, 162B for the electrical contacts 152A, 152B (e.g.,
In at least one example embodiment, each of the contact members 152′, 152″ (of the electrical contacts 152A, 152B) includes a continuous spring feature 156A, 156B that extends from each base 154A, 154B. The continuous spring features 156A, 156B may have a planar, winding form. The continuous spring features 156A, 156B are movable between a first compressed position and a second extended position (e.g., in a perpendicular direction relative to each base 154A, 154B).
In at least one example embodiment, each of the contact members 152′, 152″ (of the electrical contacts 152A, 152B) includes a contact pin or contact surface 158A, 158B that extends from the respective continuous spring features 156A, 156B. For example, the contact surfaces 158A, 158B extend from the respective continuous spring features 156A, 156B at an end distal from the base 154A, 154B. The contact surfaces 158A, 158B may extend from the respective continuous spring features 156A, 156B and into the capsule-receiving cavity 130, such that the contact surfaces 158A, 158B may make contact with the capsule 200 therein (e.g., via end sections of the capsule 200 analogous to the first end section 1342 and the second end section 1346 of the capsule 1300).
In this manner, the contact surfaces 158A, 158B are spring-loaded so as to enhance an engagement with the capsule 200. For example, the contact surfaces 158A, 158B may extend into the capsule-receiving cavity 130 by a first amount when in use and by a second amount when not in use. The first amount may be smaller than the second amount. For example, when in use, the contact surfaces 158A, 158B may extend into the capsule-receiving cavity 130 by about 0.20 mm (i.e., first amount) as a result of the continuous spring features 156A, 156B being in a compressed or loaded state. On the other hand, when not in use, the contact surfaces 158A, 158B may extend into the capsule-receiving cavity 130 by about 0.90 mm (i.e., second amount) as a result of the continuous spring features 156A, 156B being in an uncompressed or unloaded state. In this manner, in at least one example embodiment, the electrical contacts 152A, 152B are configured such that a connection with the capsule 200 is not established until the full insertion of the capsule 200 into the capsule-receiving cavity 130.
In at least one example embodiment, as illustrated best in
In at least one example embodiment, the method of control/heating and associated circuitry and electrical contacts (e.g., capsule connector 132 including the one or more electrical connectors or contacts 152A, 152B) may be as described in U.S. application Ser. No. 17/151,375, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Energy Based Heater Control, And Methods Of Controlling A Heater” (Atty. Dkt. No. 24000NV-000668-US), filed Jan. 18, 2021; and U.S. application Ser. No. 17/151,409, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Intra-Draw Heater Control, and Methods of Controlling a Heater” (Atty. Dkt. No. 24000NV-000670-US), filed Jan. 18, 2021, the entire contents of each of which are incorporated herein by reference.
The capsule 200 is loaded into the aerosol-generating device 100 by initially inserting the capsule 200 into the capsule-receiving cavity 130 defined by the capsule connector 132. In at least one example embodiment, the capsule 200 makes contact (e.g., full contact) with the electrical contacts 152A, 152B within capsule-receiving cavity 130 only upon the application of force (e.g., downward/inward force) to the capsule 200. In at least one example embodiment, a force is applied to the capsule 200 by the closure and/or latching of the lid 110. In other example embodiments, a force is applied to the capsule 200 by an adult consumer. In still other example embodiments, a force is applied by a combination of pressure applied by the adult consumer and the closure and/or latching of the lid 110. For example, in each instance, a forced is applied until a resistance is felt and/or a clicking sound is heard, which signals a complete engagement of the capsule 200 in the capsule-receiving cavity 130.
The underside of the lid 110 may include an impingement/engagement member or surface 113 configured to engage the capsule 200 when the lid 110 is pivoted to transition to a closed position. The impingement/engagement member or surface 113 of the lid 110 may include a recess (e.g., that corresponds to the size and shape of the capsule 200) and/or a resilient material to enhance an interface with the capsule 200 so as to provide the desired seal. When the capsule 200 is inserted into the capsule-receiving cavity 130, the weight of the capsule 200 itself may not be sufficient to compress the electrical contacts 152A, 152B (e.g., at least not to any significant degree). As a result, the capsule 200 may simply rest on the exposed pins of the electrical contacts 152A, 152B (e.g., contact surfaces 158A, 158B of the contact members 152′/152″) without any compression (or without any significant compression) of the electrical contacts 152A, 152B. Additionally, the weight of the lid 110 itself, when pivoted to transition to a closed position, may not compress the electrical contacts 152A, 152B to any significant degree and, instead, may simply rest on the capsule 200 in an intermediate, partially open/closed position. In such an instance, a deliberate action (e.g., downward force) to close the lid 110 will cause the impingement/engagement member or surface 113 of the lid 110 to press down onto the capsule 200 to provide the desired seal and also cause the capsule 200 to compress and, thus, fully engage electrical contacts 152A, 152B. Additionally, a full closure of the lid 110 will result in an engagement with the latch 114, which will maintain the closed position and the desired mechanical/electrical engagements involving the capsule 200 until released (e.g., via the latch release button 118). The force requirement for closing the lid 110 may help to ensure and/or improve air/aerosol sealing and to provide a more robust electrical connection, as well as improved device and thermal efficiency and battery life by reducing or eliminating early power draws and/or parasitic heating of the capsule 200.
In at least one example embodiment, such as best illustrated in
In at least one example embodiment, as best illustrated in
In at least one example embodiment, the bottom end 166D of the capsule-receiving cavity 130 includes one or more alignment members that are configured to help ensure a correct alignment between the capsule 200 and the electrical contacts 152A, 152B. In at least one example embodiment, as best illustrated in
The distal/upstream end of the capsule 200 may have a shape that corresponds with the one or more alignment members formed within the capsule-receiving cavity 130. As a result, the capsule 200 may be properly aligned in a relatively simple and consistent manner when loaded within the aerosol-generating device 100. When the capsule 200 is inserted into the capsule-receiving cavity 130, the end sections of the capsule 200 (which may be analogous to the first end section 1342 and the second end section 1346 of the capsule 1300) may initially come to rest on the electrical contacts 152A, 152B. A downward/inward force on the capsule 200 (e.g., via the closing of the lid 110) will urge the capsule 200 downward/inward so as to cause the electrical contacts 152A, 152B to compress (e.g., via the spring features 156A, 156B of the contact members 152′, 152″) and, thus, retract into the capsule connector 132. As a result, while pressed against the electrical contacts 152A, 152B, the end sections of the capsule 200 (which may be analogous to the first end section 1342 and the second end section 1346 of the capsule 1300) may also contact the flat surfaces 174 of the alignment members in the capsule-receiving cavity 130. Additionally, the alignment recess of the capsule 200 (which may be analogous to the alignment recess 1326 of the capsule 1300) may contact or otherwise be adjacent to the angled surfaces 176 of the alignment members in the capsule-receiving cavity 130. Furthermore, the inlet recess of the capsule 200 (which may be analogous to the inlet recess 1328 of the capsule 1300) may receive the capsule seal 202 for a resilient engagement. In such instances, a relatively close fit and, consequently, a secure electrical connection and desirable seal may be established with the capsule 200.
The first end 192 may have an oblong or elliptical shape and may include one or more outlets 196. For example, as illustrated, the first end 192 may include four outlets 196, such that four or more different areas or quadrants of the adult consumer's mouth can be engaged during use of the aerosol-generating device 100. The second end 194 may be coupleable to the lid 110. For example, in at least one example embodiment, the second end 194 includes a ledge 197, one or more ridges 195, and one or more coupling structures 198. The ledge 197 may include a recessed portion 193 and, in at least one example embodiment, the one or more ridges 195 may extend perpendicularly (or substantially in a perpendicular direction) from the recessed portion 193. In other example embodiments, the one or more ridges 195 may extend perpendicularly (or substantially in a perpendicular direction) from a main surface of the ledge 197. The ledge 197 and the one or more ridges 195 may be configured to position or align the replaceable mouthpiece 190 with respect to the lid 110. The one or more coupling structures 198 may be configured to couple the replaceable mouthpiece 190 to the lid 110. The one or more coupling structures 198 may be bubble or projection couplers. For example, as illustrated, the replaceable mouthpiece 190 may include four bubble or projection couplers, two disposed along each major length of the second end 194 of the replaceable mouthpiece 190.
In at least one example embodiment, the replaceable mouthpiece 190 may be inserted through an opening 111 of the lid 110 that is configured to receive and secure the second end 194 of the replaceable mouthpiece 190 (e.g., via a snap-fit arrangement). In this manner, as illustrated best in
The first end 592 of the replaceable mouthpiece 590 includes one or more outlets 596. For example, as illustrated, the first end 592 may include four outlets 596 (e.g., diverging outlets), such that four or more different areas or quadrants of the consumer's mouth can be engaged during use of the aerosol-generating device 500. The second end 594 is coupleable to the lid 110. For example, in at least one example embodiment, the second end 594 includes a ledge 597, one or more ridges 595, and one or more coupling structures 598. The ledge 597 may include a recessed portion 593 and, in at least one example embodiment, the one or more ridges 595 may extend perpendicularly (or substantially in a perpendicular direction) from the recessed portion 593. In other example embodiments, the one or more ridges 595 may extend perpendicularly (or substantially in a perpendicular direction) from a main surface of the ledge 597. The ledge 597 and the one or more ridges 595 may be configured to position or align the replaceable mouthpiece 590 with respect to the lid 110. The one or more coupling structures 598 may be configured to couple the replaceable mouthpiece 590 to the lid 110. The one or more coupling structures 598 may be bubble or projection couplers. For example, as illustrated, the replaceable mouthpiece 590 may include four bubble or projection couplers, two disposed along each major length of the second end 594 of the replaceable mouthpiece 590.
The aerosol-generating device in accordance with at least some example embodiments (such as the aerosol-generating device 100 illustrated in
As discussed herein, an aerosol-forming substrate is a material or combination of materials that may yield an aerosol. An aerosol relates to the matter generated or output by the devices disclosed, claimed, and equivalents thereof. The material may include a compound (e.g., nicotine, cannabinoid), where an aerosol including the compound is produced when the material is heated. The heating may be below the combustion temperature so as to produce an aerosol without involving a substantial pyrolysis of the aerosol-forming substrate or the substantial generation of combustion byproducts (if any). Thus, in at least one example embodiment, pyrolysis does not occur during the heating and resulting production of aerosol. In other instances, there may be some pyrolysis and combustion byproducts, but the extent may be considered relatively minor and/or merely incidental.
The aerosol-forming substrate may be a fibrous material. For instance, the fibrous material may be a botanical material. The fibrous material is configured to release a compound when heated. The compound may be a naturally occurring constituent of the fibrous material. For instance, the fibrous material may be plant material such as tobacco, and the compound released may be nicotine. The term “tobacco” includes any tobacco plant material including tobacco leaf, tobacco plug, reconstituted tobacco, compressed tobacco, shaped tobacco, or powder tobacco, and combinations thereof from one or more species of tobacco plants, such as Nicotiana rustica and Nicotiana tabacum.
In some example embodiments, the tobacco material may include material from any member of the genus Nicotiana. In addition, the tobacco material may include a blend of two or more different tobacco varieties. Examples of suitable types of tobacco materials that may be used include, but are not limited to, flue-cured tobacco, Burley tobacco, Dark tobacco, Maryland tobacco, Oriental tobacco, rare tobacco, specialty tobacco, blends thereof, and the like. The tobacco material may be provided in any suitable form, including, but not limited to, tobacco lamina, processed tobacco materials, such as volume expanded or puffed tobacco, processed tobacco stems, such as cut-rolled or cut-puffed stems, reconstituted tobacco materials, blends thereof, and the like. In some example embodiments, the tobacco material is in the form of a substantially dry tobacco mass. Furthermore, in some instances, the tobacco material may be mixed and/or combined with at least one of propylene glycol, glycerin, sub-combinations thereof, or combinations thereof.
The compound may also be a naturally occurring constituent of a medicinal plant that has a medically-accepted therapeutic effect. For instance, the medicinal plant may be a Cannabis plant, and the compound may be a cannabinoid. Cannabinoids interact with receptors in the body to produce a wide range of effects. As a result, cannabinoids have been used for a variety of medicinal purposes (e.g., treatment of pain, nausea, epilepsy, psychiatric disorders). The fibrous material may include the leaf and/or flower material from one or more species of Cannabis plants such as Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some instances, the fibrous material is a mixture of 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica.
Examples of cannabinoids include tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), cannabidiolic acid (CBDA), cannabidiol (CBD), cannabinol (CBN), cannabicyclol (CBL), cannabichromene (CBC), and cannabigerol (CBG). Tetrahydrocannabinolic acid (THCA) is a precursor of tetrahydrocannabinol (THC), while cannabidiolic acid (CBDA) is precursor of cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) may be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, via heating. In at least one example embodiment, heat from a heater may cause decarboxylation so as to convert the tetrahydrocannabinolic acid (THCA) in the capsule to tetrahydrocannabinol (THC), and/or to convert the cannabidiolic acid (CBDA) in the capsule to cannabidiol (CBD).
In instances where both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the capsule, the decarboxylation and resulting conversion will cause a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of the tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) during the heating of the capsule. Similarly, in instances where both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the capsule, the decarboxylation and resulting conversion will cause a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of the cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD) during the heating of the capsule.
Furthermore, the compound may be or may additionally include a non-naturally occurring additive that is subsequently introduced into the fibrous material. In one instance, the fibrous material may include at least one of cotton, polyethylene, polyester, rayon, combinations thereof, or the like (e.g., in a form of a gauze). In another instance, the fibrous material may be a cellulose material (e.g., non-tobacco and/or non-Cannabis material). In either instance, the compound introduced may include nicotine, cannabinoids, and/or flavorants. The flavorants may be from natural sources, such as plant extracts (e.g., tobacco extract, Cannabis extract), and/or artificial sources. In yet another instance, when the fibrous material includes tobacco and/or Cannabis, the compound may be or may additionally include one or more flavorants (e.g., menthol, mint, vanilla). Thus, the compound within the aerosol-forming substrate may include naturally occurring constituents and/or non-naturally occurring additives. In this regard, it should be understood that existing levels of the naturally occurring constituents of the aerosol-forming substrate may be increased through supplementation. For example, the existing levels of nicotine in a quantity of tobacco may be increased through supplementation with an extract containing nicotine. Similarly, the existing levels of one or more cannabinoids in a quantity of Cannabis may be increased through supplementation with an extract containing such cannabinoids.
In at least one example embodiment, the aerosol-forming substrate has a resistance-to-draw (RTD), e.g., as contained within a capsule, of greater than or equal to about 30 mmH2O (e.g., greater than or equal to about 40 mmH2O, greater than or equal to about 50 mmH2O, greater than or equal to about 60 mmH2O, greater than or equal to about 70 mmH2O, greater than or equal to about 80 mmH2O, greater than or equal to about 90 mmH2O, greater than or equal to about 100 mmH2O, greater than or equal to about 110 mmH2O, or greater than or equal to about 120 mmH2O). In at least one example embodiment, the RTD is less than or equal to about 130 mmH2O (e.g., less than or equal to about 120 mmH2O, less than or equal to about 110 mmH2O, less than or equal to about 100 mmH2O, less than or equal to about 90 mmH2O, less than or equal to about 80 mmH2O, less than or equal to about 70 mmH2O, less than or equal to about 60 mmH2O, less than or equal to about 50 mmH2O, or less than or equal to about 40 mmH2O). In at least one example embodiment, the RTD ranges from about 60 mmH2O to about 80 mmH2O (e.g., from about 65 mmH2O to about 75 mmH2O, from about 67 mmH2O to about 73 mmH2O, or from about 69 mmH2O to about 71 mmH2O).
In at least one example embodiment, the aerosol-forming substrate has a bulk density of greater than or equal to about 0.2 g/cm3 (e.g., greater than or equal to about 0.25 g/cm3, greater than or equal to about 0.3 g/cm3, greater than or equal to about 0.35 g/cm3, greater than or equal to about 0.4 g/cm3, greater than or equal to about 0.45 g/cm3, greater than or equal to about 0.5 g/cm3, greater than or equal to about 0.55 g/cm3, greater than or equal to about 0.6 g/cm3, greater than or equal to about 0.65 g/cm3, greater than or equal to about 0.7 g/cm3, greater than or equal to about 0.75 g/cm3). In at least one example embodiment, the bulk density is less than or equal to about 0.8 g/cm3 (e.g., less than or equal to about 0.75 g/cm3, less than or equal to about 0.7 g/cm3, less than or equal to about 0.65 g/cm3, less than or equal to about 0.6 g/cm3, less than or equal to about 0.55 g/cm3, less than or equal to about 0.5 g/cm3, less than or equal to about 0.45 g/cm3, less than or equal to about 0.4 g/cm3, less than or equal to about 0.35 g/cm3, less than or equal to about 0.3 g/cm3, or less than or equal to about 0.25 g/cm3). In at least one example embodiment, the bulk density ranges from about 0.3 g/cm3 to about 0.5 g/cm3 (e.g., from about 0.35 g/cm3 to about 0.45 g/cm3, or from about 0.37 g/cm3 to about 0.43 g/cm3).
In at least one example embodiment, the aerosol-forming substrate has a particulate form with a mean particle size (e.g., diameter) of greater than or equal to about 270 μm (e.g., greater than or equal to about 280 μm, greater than or equal to about 290 μm, greater than or equal to about 300 μm, greater than or equal to about 310 μm, greater than or equal to about 320 μm, greater than or equal to about 330 μm, greater than or equal to about 340 μm, greater than or equal to about 350 μm, greater than or equal to about 360 μm, greater than or equal to about 370 μm, greater than or equal to about 380 μm, greater than or equal to about 390 μm, greater than or equal to about 400 μm, or greater than or equal to about 410 μm). In at least one example embodiment, the mean particle size is less than or equal to about 415 μm (e.g., less than or equal to about 410 μm, less than or equal to about 400 μm, less than or equal to about 390 μm, less than or equal to about 380 μm, less than or equal to about 370 μm, less than or equal to about 360 μm, less than or equal to about 350 μm, less than or equal to about 340 μm, less than or equal to about 330 μm, less than or equal to about 320 μm, less than or equal to about 310 μm, less than or equal to about 300 μm, less than or equal to about 290 μm, or less than or equal to about 280 μm).
In at least one example embodiment, the aerosol-forming substrate has a 10th percentile diameter ranging from about 160 μm to about 225 μm. In at least one example embodiment, the aerosol-forming substrate has a 50th percentile (or median) diameter ranging from about 260 μm to about 385 μm. In at least one example embodiment, the aerosol-forming substrate has a 90th percentile diameter ranging from about 390 μm to about 635 μm.
The aerosol-generating device in accordance with at least some example embodiments (such as, the aerosol-generating device 100 illustrated in
When the capsule 200 is fully seated within the capsule-receiving cavity 130, the end sections of the capsule 200 (which may be analogous to the first end section 1342 and the second end section 1346 of the capsule 1300) will be pressed against the electrical contacts 152A, 152B (e.g., pressed against the exposed tips of the contact surfaces 158A, 158B of the contact members 152′, 152″), which will, in turn, be compressed and retracted via the spring features 156A, 156B of the contact members 152′, 152″. While pressed against the electrical contacts 152A, 152B, the end sections of the capsule 200 (which may be analogous to the first end section 1342 and the second end section 1346 of the capsule 1300) may also contact the flat surfaces 174 of the alignment members in the capsule-receiving cavity 130. Additionally, the alignment recess of the capsule 200 (which may be analogous to the alignment recess 1326 of the capsule 1300) may contact or otherwise be adjacent to the angled surfaces 176 of the alignment members in the capsule-receiving cavity 130. Furthermore, the inlet recess of the capsule 200 (which may be analogous to the inlet recess 1328 of the capsule 1300) may receive the capsule seal 202 for a resilient engagement. As a result, a relatively secure electrical connection and desirable seal may be established with the capsule 200.
The aerosol-generating device 100 or the aerosol-generating device 500 and/or the aerosol-generating device 5100 may be activated using the consumer interface panel 143 (e.g., by pressing the power button 142) and/or upon the detection of a draw event (e.g., via the flow sensor 185). Upon activation, the control circuitry 160 is configured to instruct the power source 150 to supply an electrical current to the capsule 200 via the electrical contacts 152A, 152B in the capsule-receiving cavity 130. Specifically, the capsule 200 includes a heater (which may be analogous to the heater 1340 of the capsule 1300) that is configured to undergo resistive heating in response to the electrical current from the power source 150 that is introduced via its end sections (which may be analogous to the first end section 1342 and the second end section 1346 of the capsule 1300). As a result of the resistive heating, the temperature of the aerosol-forming substrate within the capsule 200 will increase such that volatiles are released so as to generate an aerosol.
In at least one example embodiment, the heating of the aerosol-forming substrate within the capsule 200 may be below a combustion temperature of the aerosol-forming substrate so as to produce an aerosol without involving a substantial pyrolysis of the aerosol-forming substrate or the substantial generation of combustion byproducts (if any). Thus, in at least one example embodiment, pyrolysis does not occur during the heating and resulting production of aerosol. In other instances, there may be some pyrolysis and combustion byproducts, but the extent may be considered relatively minor and/or merely incidental. The method of heating/control may be as described in U.S. application Ser. No. 17/151,375, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Energy Based Heater Control, And Methods Of Controlling A Heater” (Atty. Dkt. No. 24000NV-000668-US), filed Jan. 18, 2021; and U.S. application Ser. No. 17/151,409, titled “Heat-Not-Burn (HNB) Aerosol-Generating Devices Including Intra-Draw Heater Control, and Methods of Controlling a Heater” (Atty. Dkt. No. 24000NV-000670-US), filed Jan. 18, 2021, the entire contents of each of which are incorporated herein by reference.
Upon a draw or application of negative pressure to the aerosol-generating device 100 (e.g., via the mouthpiece 190) or the aerosol-generating device 500 (e.g., via the mouthpiece 590) and/or the aerosol-generating device 5100 (e.g. via the mouthpiece 5190), ambient air is drawn into the aerosol-generating device 100 or the aerosol-generating device 500 or the aerosol-generating device 5100 through the pores 173 in the grille 172. Once inside, the air streams from the pores 173 converge and may pass through an air channel assembly 181 before being directed to the air hose 180. The converged airflow may be optionally detected/monitored with a flow sensor 185 within the air channel assembly 181 and/or the air hose 180. From the air hose 180, the airflow is directed to the air inlet connection 184 of the capsule connector 132. The airflow then travels through the capsule seal 202 and enters the inlet openings in the capsule 200 (which may be analogous to the openings 1322 in the capsule 1300). Inside the capsule 200, the air may flow (e.g., longitudinally) through the aerosol-forming substrate and along the plane of the heater so as to entrain the volatiles released by the aerosol-forming substrate, which results in an aerosol. Finally, the resulting aerosol passes through the outlet openings in the capsule 200 (which may be analogous to the openings 1312 in the capsule 1300) before exiting the aerosol-generating device 100 (e.g., via the outlets 196 in the mouthpiece 190) or the aerosol-generating device 500 (e.g., via the outlets 596 in the mouthpiece 590) or the aerosol-generating device 5100 (e.g., via the outlets 5196 in the mouthpiece 5190).
In at least one example embodiment, the method of use regarding the aerosol-generating device 100 or the aerosol-generating device 500 or the aerosol-generating device 5100 may include securing the replaceable mouthpiece (e.g., replaceable mouthpiece 190 and/or replaceable mouthpiece 590) to the lid (e.g., 110). For example, the method may include inserting the replaceable mouthpiece into the opening (e.g., opening 111) of the lid when the lid is in an opened position until resistance is felt and/or a click is heard. In at least one example embodiment, the method of use may include replacing the replaceable mouthpiece (e.g., replaceable mouthpiece 190 and/or replaceable mouthpiece 590 and/or replaceable mouthpiece 5100). Replacing the replaceable mouthpiece may including opening the lid (e.g., 110); removing a first replaceable mouthpiece from the opening (e.g., opening 111); and inserting a second replaceable mouthpiece into the opening until resistance is felt and/or a click is heard.
Although a capsule 200 has been illustrated as one example in connection with the aerosol-generating device 100 and/or the aerosol-generating device 500 and/or the aerosol-generating device 5100, it should be understood other suitable examples are also available. Further details, variants, and alternatives of the capsule are discussed below in connections with
The first end cap 1210 defines a first opening 1212, while the second end cap 1220 defines a second opening 1222. In at least one example embodiment, the first opening 1212 is in the form of a series of outlet openings (e.g., five outlet openings), and the second opening 1222 is in the form of a series of inlet openings (e.g., five inlet openings). In another instance, instead of being arranged in series, the openings may be arranged in an array of rows and columns. Additionally, the second end cap 1220 may expose a first end section 1242 and a second end section 1246 of a heater 1240 (e.g.,
The cover 1230 may be formed of a metal/alloy, a high-temperature plastic, and/or a plant material. In some instances, the metal may include aluminum, and the alloy may be stainless steel. The high-temperature plastic may be the same as those disclosed in connection with the first end cap 1210 and the second end cap 1220. The plant material may include cellulose fibers (e.g., in the form of paper pulp). As for dimensions, the cover 1230 may have a thickness (e.g., wall thickness) of greater than or equal to about 0.4 mm to less than or equal to about 0.6 mm (e.g., about 0.5 mm), although example embodiments are not limited thereto. In addition to being wholly formed of one of the above materials, the cover 1230 may also have a composite/multi-layer structure. For instance, the cover 1230 may include an underlying/inner layer of metal combined with an overlying/outer layer of plastic and/or plant material (e.g., paper, cardboard).
When a metal/alloy is used to produce the cover 1230, the fabrication process may include extrusion of the metal/alloy to form the cover 1230. In another instance, the fabrication process may include pressing/drawing (e.g., punching an appropriate shape out of a sheet of the metal/alloy) and cutting to form the cover 1230. In yet another instance, the fabrication process may include stamping a sheet of the metal/alloy to an appropriate size/shape and folding to form the cover 1230 followed by an optional seam welding and/or application of a label. These latter two processes may reduce fabrication costs.
The capsule 1200 may have a cuboid-like shape which includes a front face, a rear face opposite the front face, a first side face between the front face and the rear face, a second side face opposite the first side face, a downstream end face, and an upstream end face opposite the downstream end face. To receive the capsule 1200, it should be understood that the capsule-receiving cavity (e.g., capsule-receiving cavity 130 of the aerosol-generating device 100) may be configured to accommodate such a shape. Although the capsule 1200 is illustrated as having a cuboid-like shape (e.g., rounded rectangular cuboid) with a rectangular cross-section, it should be understood that example embodiments are not limited thereto. For instance, in some embodiments, the capsule 1200 may have a shape wherein an end view or cross-section resembles a rectangle with a pair of opposing semicircular ends (e.g., elongated circle, obround, discorectangle, stadium, racetrack), an oval/ovoid, or an ellipse. The chamber defined within the capsule 1200 may have the same or a different shape as the exterior of the capsule 1200. For instance, the cross-sections of the chamber and the exterior of the capsule 1200 may both be rectangular. In another instance, the cross-section of the chamber may be non-rectangular (e.g., obround), while the cross-section of the exterior of the capsule 1200 may be rectangular (or vice versa).
In an alternative embodiment, the first end cap 1210 may be integrated with the cover 1230 so as to constitute a single structure. For instance, the fabrication process may include pressing/drawing a metal sheet such that the first end cap 1210 and the cover 1230 are integrally formed of the same material (e.g., as a continuous shell). The first opening 1212 may pre-punched into the metal sheet before the pressing/drawing or post-punched into the metal sheet after the pressing/drawings.
The heater 1240 includes a first end section 1242, an intermediate section 1244, and a second end section 1246. The first end section 1242 and the second end section 1246 include external segments of the heater 1240 configured to establish an electrical connection with a power source (e.g., for receiving an electric current from the power source 150). During manufacturing, the heater 1240 may be embedded within the second end cap 1220 via injection molding (e.g., insert molding, overmolding). The intermediate section 1244 is an internal segment of the heater 1240 configured to heat the aerosol-forming substrate (e.g., aerosol-forming substrate 1860 in
The aerosol-forming substrate for the capsule 1200 may be in a consolidated form or in a loose form. Specifically, when in a consolidated form, the aerosol-forming substrate may have a shape that facilitates its placement within the housing. For instance, the aerosol-forming substrate may be in the form of one or more rectangular sheets/slabs dimensioned for insertion into the cover 1230. When in a loose form, the aerosol-forming substrate may be loaded into the cover 1230 via a vacuum-assisted process. With such a process, the housing may first be partially assembled such that the second end cap 1220 (with the heater 1240 embedded therein) is engaged with the cover 1230. A vacuum may then be applied to the second opening 1222 of the second end cap 1220 to pull aerosol-forming substrate provided in the vicinity into the open end of the cover 1230. The level of the vacuum may be varied as appropriate to achieve the desired density of the aerosol-forming substrate for the capsule 1200. In this manner, a plurality of capsules may be loaded simultaneously and relatively consistently.
The intermediate section 1244 of the heater 1240 may have a planar and winding form resembling a compressed oscillation or zigzag with a plurality of parallel segments (e.g., eight to sixteen parallel segments). Each parallel segment may have a width of greater than or equal to about 0.28 mm to less than or equal to about 0.32 mm (e.g., about 0.30 mm) and a spacing between parallel segments of greater than or equal to about 0.30 mm to less than or equal to about 0.34 mm (e.g., about 0.32 mm), although other dimensions are also possible. In at least one example embodiment, the intermediate section 1244 may occupy a rectangular area so as to more fully heat the chamber within the cover 1230. However, it should be understood that other forms for the intermediate section 1244 of the heater 1240 are also possible (e.g., spiral form, flower-like form). Additionally, the terminus of each of the first end section 1242 and the second end section 1246 may be oriented orthogonally to the plane of the intermediate section 1244. Furthermore, each of the first end section 1242 and the second end section 1246 may include a segment having a sideways, square J-shape which facilitates a transition from the plane of the intermediate section 1244 to the orthogonal plane of the electrical contact surfaces of the first end section 1242 and the second end section 1246. In this regard, the first end section 1242 and the second end section 1246 may also be viewed as resembling a pair of “feet” of the heater 1240. As a result, the first end section 1242 and the second end section 1246 may be embedded relatively securely within the second end cap 1220 while providing a pair of electrical contact surfaces (e.g., for engagement with the electrical contacts 152a and 152b of the aerosol-generating device 100).
The first end cap 1310 defines a first opening 1312, while the second end cap 1320 defines a second opening 1322. In at least one example embodiment, the first opening 1312 is in the form of a series of outlet openings (e.g., nine outlet openings), and the second opening 1322 is in the form of a series of inlet openings (e.g., eight inlet openings). In another instance, instead of being arranged in series, the openings may be arranged in an array of rows and columns. Additionally, each of the openings may have a width of greater than or equal to about 0.26 mm to less than or equal to about 0.30 mm (e.g., about 0.28 mm) to reduce or prevent the egress of particles of the aerosol-forming substrate. Although rectangular recesses are shown on the sides of the first end cap 1310 and the second end cap 1320, it should be understood that these features (e.g., gating features) are the result of a manufacturing process (e.g., injection molding) and may be omitted is some embodiments. Furthermore, the second end cap 1320 may expose a first end section 1342 and a second end section 1346 of a heater 1340 (e.g.,
As shown in the drawings, the capsule 1300 has a shape wherein an end view or cross-section resembles a rectangle with a pair of opposing semicircular ends (e.g., elongated circle, obround, discorectangle, stadium, racetrack). The shape of the capsule 1300 may also be viewed as one wherein a cylinder has been diametrically elongated or flattened along its longitudinal axis. However, it should be understood that the capsule 1300 may have other suitable shapes. For example, in some instances, the capsule 1300 may have an ovoid or ellipsoid shape with an oval or elliptical cross-section. In other instances, the capsule 1300 may have a cuboid-like shape (e.g., rounded rectangular cuboid) with a rectangular cross-section. The chamber defined within the capsule 1300 may have the same or a different shape as the exterior of the capsule 1300. For instance, the cross-sections of the chamber and the exterior of the capsule 1300 may both be obround. In another instance, the cross-section of the chamber may be non-obround (e.g., rectangular), while the cross-section of the exterior of the capsule 1300 may be obround (or vice versa).
In addition to the second opening 1322, the second end cap 1320 also defines an alignment recess 1326 and an inlet recess 1328. The alignment recess 1326 and the inlet recess 1328 may be viewed as being in a multi-level arrangement, wherein the base/inner end surface of the alignment recess 1326 (which exposes the first end section 1342 and the second end section 1346) may be regarded as being on one level, while the base/inner end surface of the inlet recess 1328 (or the grille-like surface of the second opening 1322) may be regarded as being on another level. The alignment recess 1326 is configured to facilitate a positioning of the capsule 1300 during its insertion into the device body of an aerosol-generating device. In at least one example embodiment, the alignment recess 1326 has angled sidewalls which taper inward toward the inlet recess 1328. With the angled sidewalls, the alignment recess 1326 may be quickly coupled with a corresponding engagement member of the device body with greater ease. For instance, when received within the capsule-receiving cavity 130 of the aerosol-generating device 100, the alignment recess 1326 of the capsule 1300 may be engaged with the angled surfaces 176, while the inlet recess 1328 of the capsule 1300 may be engaged with the capsule seal 202. As a result, the capsule 1300 may be properly loaded and aligned within the device body of the aerosol-generating device in a relatively consistent manner.
The first end cap 1310 and the second end cap 1320 may be configured to include lead-in features to facilitate their introduction into the cover 1330. For instance, the first end cap 1310 may have a distal end with a periphery in a form of a tapered edge. Similarly, the second end cap 1320 may have a proximal end with a periphery in a form of a tapered edge. Such configurations may ease the insertions of the first end cap 1310 and the second end cap 1320 into the cover 1330 (e.g., via press fitting) during the assembly of the capsule 1300.
The terminus of each of the first end section 1342 and the second end section 1346 may be oriented orthogonally to the plane of the intermediate section 1344. Each of the first end section 1342 and the second end section 1346 may also include segments having a sideways J-shape. Furthermore, each of the first end section 1342 and the second end section 1346 may include opposing finger/claw-like structures. The finger/claw-like structures may serve as locating features for manufacturing equipment (e.g., overmolding tool). As a result, the first end section 1342 and the second end section 1346 may be embedded relatively securely within the second end cap 1320 while providing a pair of electrical contact surfaces.
As illustrated, the sides of the first end cap 1410 and the second end cap 1420 may be devoid of rectangular recesses (e.g., gating features) present in some other embodiments (e.g., compare with capsule 1300 in
In another variation, the first end cap 1410 and/or the second end cap 1420 may be configured to be fully seated within the cover 1430. For example, the downstream end face of the first end cap 1410 may be flush (or slightly sub-flush) with the downstream rim of the cover 1430. Similarly, the upstream end face of the second end cap 1420 may be flush (or slightly sub-flush) with the upstream rim of the cover 1430.
As illustrated, the first end cap 1510 and the second end cap 1520 may overlap with the cover 1530. Specifically, the periphery of each of the first end cap 1510 and the second end cap 1520 may be greater than the periphery of the cover 1530 so that the opposite ends of the cover 1530 can be received within the first end cap 1510 and the second end cap 1520. In such an instance, the first end cap 1510 and the second end cap 1520 may interface with the outer surface of the cover 1530. In another instance, the first end cap 1510 and the second end cap 1520 may interface with both the outer surface and the inner surface of the cover 1530. In either instance, the first end cap 1510 and the second end cap 1520 may include sealing ridges configured to interface with the cover 1530 to provide the desired air seal. Furthermore, the overlapping configuration of
As illustrated, the first end cap 1610 may overlap with the cover 1630. Specifically, the periphery of the first end cap 1610 may be greater than the periphery of the cover 1630 so that the proximal end of the cover 1630 can be received within the first end cap 1610. In such an instance, the first end cap 1610 may interface with the outer surface of the cover 1630, while the second end cap 1620 may interface with the inner surface of the cover 1630. Conversely, in another instance, the first end cap 1610 may interface with the inner surface of the cover 1630, while the second end cap 1620 may interface with the outer surface of the cover 1630. In either instance, the first end cap 1610 and the second end cap 1620 may include sealing ridges configured to interface with the cover 1630 to provide the desired air seal. Furthermore, the overlapping configuration of
As illustrated, the cover 1730 may be a composite structure including an inner shell and an outer wrapper. The inner shell of the cover 1730 may be formed of a metal/alloy or a high-temperature plastic, while the outer wrapper of the cover 1730 may be formed of an insulating and/or fibrous material (e.g., pulp/cork wrapper, paper label). For instance, the material of the outer wrapper of the cover 1730 may be one that allows for printing (e.g., branding/aesthetics or other information). When the capsule 1700 is assembled, the side surfaces of the first end cap 1710 and the second end cap 1720 may be substantially flush with the adjacent/adjoining surfaces of the cover 1730. Furthermore, the composite structure of the cover 1730 may improve the thermal properties (e.g., heat insulating effect for safer handling) and/or the aesthetic characteristics of the capsule 1700.
As shown in
The controller 2105 may be hardware including logic circuits; a hardware/software combination such as a processor executing software; or a combination thereof. For example, the controller 2105 may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, application-specific integrated circuit (ASIC), etc.
In the event where the controller 2105 is, or includes, a processor executing software, the controller 2105 is configured as a special purpose machine (e.g., a processing device) to execute the software, stored in memory accessible by the controller 2105 (e.g., the storage medium 2145 or another storage device), to perform the functions of the controller 2105. The software may be embodied as program code including instructions for performing and/or controlling any or all operations described herein as being performed by the controller 2105.
As disclosed herein, the term “storage medium”, “computer readable storage medium” or “non-transitory computer readable storage medium” may represent one or more devices for storing data, including read only memory (ROM), random access memory (RAM), magnetic RAM, core memory, magnetic disk storage mediums, optical storage mediums, flash memory devices and/or other tangible machine readable mediums for storing information. The term “computer-readable medium” may include, but is not limited to, portable or fixed storage devices, optical storage devices, and various other mediums capable of storing, containing or carrying instruction(s) and/or data.
The controller 2105 communicates with the power supply 2110, the actuator control 2115, the electrical/data interface 2120, the device sensors 2125, the input/output (I/O) interfaces 2130, the aerosol indicators 2135, on-product controls 2150, and/or the at least one antenna 2140, etc. According to at least some example embodiments, the on-product controls 2150 can include any device or devices capable of being manipulated manually by an adult operator to indicate a selection of a value. Example implementations include, but are not limited to, one or more buttons, a dial, a capacitive sensor, and a slider, etc.
The controller 2105 (or storage medium 2145) stores key material and proprietary algorithm software for the encryption. For example, encryption algorithms rely on the use of random numbers. The security of these algorithms depends on how truly random these numbers are. These numbers are usually pre-generated and coded into the processor or memory devices. Example embodiments may increase the randomness of the numbers used for the encryption by using the aerosol drawing parameters (e.g., durations of instances of aerosol drawing, intervals between instances of aerosol drawing, or combinations of them) to generate numbers that are more random and more varying from individual to individual than pre-generated random numbers. All communications between the controller 2105 and the capsule 200 may be encrypted.
The controller 2105 is configured to operate a real time operating system (RTOS), control the control subsystem 2100 and may be updated through reading and/or sensing update information from a tag, chip, and/or label (e.g., a security tag, a security chip, etc.) included on the capsule 200, through communicating with the NVM or CC-NVM, and/or when the control subsystem 2100 is connected with other devices (e.g., a smart phone) through the I/O interfaces 2130 and/or the antenna 2140. For example, the update information may include parameter information related to the corresponding capsule, such as heater parameter information and/or heater profile information tailored and/or directed towards the aerosol-forming substrate contained within the installed capsule 200, capsule authentication update information with information relevant to the capsule authentication method (e.g., security settings related to the capsules, updates to the security keys used during authentication, etc.), programming updates, etc. Additionally, the I/O interfaces 2130 and the antenna 2140 allow the control subsystem 2100 to connect to various external devices such as smart phones, tablets, and PCs, etc. For example, the I/O interfaces 2130 may include a USB-C connector, a micro-USB connector, etc. The USB-C connector (e.g., connector port 114) may be used by the control subsystem 2100 to charge the power source 2110b (e.g., which may correspond to the power source 150), and may also be used to transmit and/or receive data from at least one external device, such as aerosol profiles, heater profiles, device performance log data (e.g., controller performance data, memory performance data, battery performance data, heater performance data, etc.), firmware upgrades, software upgrades, etc., but the example embodiments are not limited thereto.
The controller 2105 may include on-board RAM and flash memory to store and execute code including analytics, diagnostics and software upgrades. As an alternative, the storage medium 2145 may store the code. Additionally, in another example embodiment, the storage medium 2145 may be on-board the controller 2105.
The controller 2105 may further include on-board clock, reset and power management modules to reduce an area covered by a PCB in the device body housing.
The device sensors 2125 may include a number of sensor transducers that provide measurement information to the controller 2105. The device sensors 2125 may include a power supply temperature sensor, an external capsule temperature sensor, a current sensor for the heater, power supply current sensor, airflow sensor and an accelerometer to monitor movement and orientation. The power supply temperature sensor and external capsule temperature sensor may be a thermistor or thermocouple and the current sensor for the heater and power supply current sensor may be a resistive based sensor or another type of sensor configured to measure current. The air flow sensor (e.g., flow sensor 185) may be a pressure sensor (e.g., a capacitive pressure sensor, etc.) configured to detect positive or negative air pressure (e.g., a draw or a puff), a microelectromechanical system (MEMS) flow sensor, and/or another type of sensor configured to measure air flow such as a hot-wire anemometer. Further, instead of, or in addition to, measuring air flow using a flow sensor included in the device sensors 2125 of the control subsystem 2100 of the device body housing, air flow may be measured using a hot wire anemometer 2220A located in the capsule 200. According to at least one example embodiment, the device sensors 2125 further includes a capsule detection sensor for detecting the presence of the capsule in the aerosol-generating device 100, and/or a door detection sensor for detecting the closure of a door and/or lid of the aerosol-generating device, but the example embodiments are not limited thereto.
The data generated from one or more of the device sensors 2125 may be detected based on a binary signal (e.g., on/off signal) using a general purpose input/output (GPIO) circuit, etc., and/or may be sampled at a sample rate appropriate to the parameter being measured using, for example, a discrete, multi-channel analog-to-digital converter (ADC), etc.
Additionally, according to at least one example embodiment, the device sensors may further include a tag sensor, such as a barcode sensor, a secure element (SE) reader, an optical reader, a physical parameter reader, etc. The tag sensor and/or the tag antenna (e.g., RFID antenna, NFC antenna, etc.) may be used individually or in combination to detect information stored on a tag (e.g., a RFID tag, a NFC tag, a barcode tag, a SE, etc.) installed and/or attached to an exterior portion of the capsule 200, and/or may be used to detect and/or sense a physical parameter of the capsule 200, such as a resistance value of a heater included within the capsule 200, etc. The tag sensor and/or tag antenna may be arranged in physical proximity to a properly inserted capsule 200 such that information stored on the tag, such as electronic identity information, authentication information, hardware parameter information, aerosol-forming substrate information (such as aerosol-forming substrate expiration information, date of manufacture information, etc.), profile information, etc.
The controller 2105 may adapt heater profiles for an aerosol-forming substrate and other profiles based on the measurement information received from the controller 2105. For the sake of convenience, these are generally referred to as aerosol profiles. The heater profile identifies the power profile to be supplied to the heater during the few seconds when aerosol drawing takes place and/or the power profile to be supplied to the heater in between aerosol drawing instances in order to apply continual heating to the capsule (e.g., to provide an “oven mode” where a desired temperature is maintained within the capsule for a desired period of time). For example, a heater profile can deliver maximum power to the heater when an instance of aerosol drawing is initiated, but then after a second or so immediately reduce the power to halfway or a quarter way. According to at least some example embodiments, the modulation of electrical power provided to the heater may be implemented using pulse width modulation, but is not limited thereto.
In addition, a heater profile can also be modified based on a detected draw and/or application of negative pressure on the aerosol-generating device 100. The use of the flow sensor allows aerosol drawing strength to be measured and used as feedback to the controller 2105 to adjust the power delivered to the heater of the capsule 200, which may be referred to as heating or energy delivery.
According to at least some example embodiments, when the controller 2105 recognizes the capsule 200 which is currently installed (e.g., via SKU, via a unique identifier included in a tag (e.g., RFID tag, NFC tag, etc.), etc.), the controller 2105 matches an associated heating profile that is designed for that particular capsule. The controller 2105 and the storage medium 2145 will store data and algorithms that allow the generation of heating profiles for all SKUs, capsule types, aerosol-forming substrate types, etc. In another example embodiment, the controller 2105 may read the heating profile from the capsule. Additionally, the adult operators may also adjust heating profiles to suit their preferences using the on-product controls 2150, using an external device wirelessly paired with the aerosol-generating device 100 and/or connected to the aerosol-generating device 100 via the I/O interfaces 2130, etc. In other example embodiments, the controller 2105 may use the heating profile applied for a previously installed capsule, which has been stored in memory, to a currently installed capsule on the assumption that the current capsule is of a same type as the previously installed capsule, etc.
The controller 2105 may send data to and receives data from the power supply 2110. The power supply 2110 includes a power source 2110b (e.g., which may correspond to the power source 150) and a power controller 2110a to manage the power output by the power source 2110b.
The power source 2110b may be a lithium-ion battery or one of its variants, for example a lithium-ion polymer battery. Alternatively, the power source 2110b may be a nickel-metal hydride battery, a nickel cadmium battery, a lithium-manganese battery, a lithium-cobalt battery, or a fuel cell. Alternatively, the power source 2110b may be rechargeable and include circuitry allowing the battery to be chargeable by an external charging device. In that case, the circuitry, when charged, provides power for a desired (or alternatively a pre-determined) number of instances of aerosol drawing, after which the circuitry must be re-connected to an external charging device.
The power controller 2110a provides commands to the power source 2110b based on instructions from the controller 2105. For example, the power supply 2110 may receive a command from the controller 2105 to provide power to the capsule (through the capsule electrical/data interface 2120) when the capsule is detected and the adult operator activates the control subsystem 2100 (e.g., by activating a switch such as a toggle button, capacitive sensor, IR sensor). Additionally, according to some example embodiments, the controller 2105 may transmit the command to the power supply 2110 based on the proper authentication of the capsule, but the example embodiments are not limited thereto.
In addition to supplying power to the capsule, the power supply 2110 also supplies power to the controller 2105. Moreover, the power controller 2110a may provide feedback to the controller 2105 indicating performance of the power source 2110b.
The controller 2105 sends data to and receives data from the at least one antenna 2140. The at least one antenna 2140 may include a NFC modem and a Bluetooth Low Energy (LE) modem and/or other modems for other wireless technologies (e.g., WiFi, etc.). In at least one example embodiment, the communications stacks are in the modems, but the modems are controlled by the controller 2105. The Bluetooth LE modem is used for data and control communications with an application on an external device (e.g., smart phone, etc.). The NFC/Bluetooth LE/WiFi modem may be used for pairing of the aerosol-generating device 100 to the application and transmission of diagnostic information, data, profile information, capsule information, hardware parameter information, firmware updates, etc. Moreover, the Bluetooth LE/WiFi modem may be used to provide location information (for an adult operator to find the aerosol-generating device) or authentication during a purchase, etc.
As described above, the control subsystem 2100 may generate and adjust various profiles for aerosol generation. The controller 2105 uses the power supply 2110 and the actuator controls 2115 to regulate the profile for the adult operator.
The actuator controls 2115 include passive and active actuators to regulate a desired aerosol profile. For example, the device body housing may include actuators within an air inlet path and/or air inlet channel of the device body housing, such as within the air flow subsystem of the aerosol-generating device 100 (e.g., air channel assembly 181, the air hose 180, the air inlet connection 184, etc.). The actuator controls 2115 may control the flow of air within the air inlet channel using the actuators based on commands from the controller 2105 associated with the desired aerosol profile.
Moreover, the actuator controls 2115 are used to energize the heater in conjunction with the power supply 2110. More specifically, the actuator controls 2115 are configured to generate a drive waveform associated with the desired aerosol profile. As described above, each possible profile is associated with a drive waveform. Upon receiving a command from the controller 2105 indicating the desired aerosol profile, the actuator controls 2115 may produce the associated modulating waveform for the power supply 2110.
The controller 2105 supplies information to the aerosol indicators 2135 to indicate statuses and occurring operations to the adult operator. The indicators 2135 include a power indicator displayed on the display panel (e.g., communication screen 140), a separate indicator light (e.g., a LED indicator light, etc.) that may be activated when the controller 2105 senses a button pressed by the adult operator. The indicators 2135 may also include a haptic feedback motor, speaker, an indicator for a current state of an adult operator-controlled aerosol parameter (e.g., generated aerosol volume), and other feedback mechanisms.
In at least one example embodiment, as shown in
Like the aerosol-generating device 100 (and also the aerosol-generating device 500), the aerosol-generating device 5100 includes a lid 5110 and a housing 5120 that engage to form the device 5100 having an overall oval, an oblong or a pebble shape. The device 5100 has rounded corners or edges so as to comfortably and discretely fit in an adult consumer's hand.
Further, in at least one example embodiment, the aerosol-generating device 5100 includes a replaceable mouthpiece 5190 (further described with respect to
As shown in
As shown, the aerosol-generating device 5100 has a first side 5102 and a second side 5104. In at least one example embodiment, the aerosol-generating device 5100 includes an interface panel 5143 disposed on the second side 5104 (as further described and shown in
In at least one example embodiment, as shown in
In at least one example embodiment, the interface panel 5143 may include one or more light emitting diodes (LEDs). The latch release button 5118 and the power button 5142 may include raised or lowered portions that indicate function of the button. The raised or lowered portion may be identified visually or by feel. The LEDs may illuminate the entire interface panel 5143 or only a portion thereof. For example, the raised or lowered portions of the latch release button 5118 and the power button 5142 may be transparent such that light only shows through the raised or lowered portions thereof.

Like the latch 114 of the aerosol-generating device 100, the latch assembly 5801 includes the latching arm 5114 that allows the lid 5110 to be releasably coupled to the housing 5120 at the second point 5124. At least a portion of the latching arm 5114 extends through the inner housing 5800 (as shown and described with respect to
In at least one example embodiment, as shown in
In at least one example embodiment, the latch assembly 5801 also includes an inner latching lever 5805 including the latching arm 5114 and a receiving arm 5230. The inner latching lever 5805 is disposed between the pair of extensions 5810 and pivotally attached to a portion of the capsule connector 5132 via a pin 5825 that extends through the pair of extensions 5810, the inner lathing lever 5805, and the pin receiving hole 5815, such that the inner latching lever 5805 pivots with respect to the extension 5810. The latching arm 5114 is perpendicular to a point of rotation about the pin 5825 when the lid 5110 is in an open position.
In some example embodiments, a main axis of the latching arm 5114 may be perpendicular with a main axis of the receiving arm 5230. For example, the latching arm 5114 may be a projection that extends from the receiving arm 5230. The projection may include substantially parallel first and second lengths or sides 5114A, 5114B that extend from the receiving arm 5514 and a third length or side 5114C the connects the first and second lengths. As illustrated best in
As the lid 5110 is moved towards a closed position as shown in
When the lid 5110 is in the closed position, as illustrated in
In at least one example embodiment, the latch assembly 5801 also includes the latch release button 5118, which is part of the interface panel 5143 shown and described with respect to
When the lid is in the closed position, the latch release button 5118 is raised with respect to an outer surface of the interface panel 5143 because the receiving arm 5230 moves toward the housing 5120 and presses against the latch button arm 5116.
To open the lid, the latch release button 5118 is pressed. Once the latch release button 5118 is pressed, the latch button arm 5116, which is connected to the latch release button 5118, presses against the receiving arm 5230 to cause the inner latching lever 5805 to pivot such that the receiving arm 5230 moves towards the capsule connector 5132 and the latching arm 5114 disengages from the lid latch 5840 of the inner surface of the lid 5110. Namely, the latching arm 5114 moves away from an interior surface of the lid 5110 providing clearance between the latching arm 5114 and the lid latch 5840.
As best illustrated in
Like the latch release button 118, the latch release button 5118 may have a substantially circular shape with a center depression or dimple configured to direct the pressure applied by the adult consumer, although example embodiments are not limited thereto. As best illustrated in

The printed circuit board (PCB) 5111 may be the same as or like the printed circuit board (PCB) as discussed above in the content of aerosol-generating device 100 except for the addition of the magnetic sensor 5500. The magnet 5115 and the magnetic sensor 5500 may be substantially aligned when the lid 5110 is in a closed position (i.e., the latching arm 5114 engages the lid latch 5840). In other words, the magnet 5115 is positioned relative to the magnetic sensor 5500 when the lid 5110 is closed, such that a magnetic flux of the magnet 5115 interacts with the magnetic sensor 5500 to generate a signal indicative of the lid 5110 being in the closed or latched position. A control circuitry, which is the same as or like the control circuitry 160, may receive the signal, and thereafter permit the aerosol-generating device 5100 to be activated by the adult consumer when, or in response to, the closed position and/or capsule being detected.
In at least one example embodiment, as shown in
In at least one example embodiment, the first and second housing portions 5600, 5601 may each have parallel inner and outer walls along a portion thereof. For example, as shown in
In at least one example embodiment, as best illustrated in
In at least one example embodiment, the air passage 5720 extends along the length of the second side 5102 of housing 5120. For example, at a top or first end of the housing 5120, as best illustrated in
Because the air passage 5720 is defined between portions of the housing, the aerosol-generating device 5100 can omit internal tubing, like the air hose 180, and related features, as discussed in the content of aerosol-generating device 100. That is, because the air passage 5720 is integrated into the housing 5120, the aerosol-generating device 5100 requires less tubing and additional structures, easing manufacture processes and reducing costs.
In at least one example embodiment, as shown in
In at least one example embodiment, as shown in
Like the charging connector 170, the charging connector assembly 5169 can be configured to receive an electric current (e.g., via a USB/mini-USB cable) from an external power source so as to charge the power source 150 internal to the aerosol-generating device 5100. In at least one example embodiment, the charging connector assembly 5169 may define a cavity 5171 that has a projection 5175 within the cavity 5171. As in the instance of charging connector 170, in at least one example embodiment, the projection 5175 of the charging connector 5169 does not extend beyond the rim of the cavity 5171.
In at least one example embodiment, as illustrated, the charging connector assembly 5169 may further include a protective grille 5172 that surrounds the cavity 5171. Like the protective grille 172, the protective grill 5172 of the charging connector assembly 5169 can help to reduce and/or prevent debris ingress and/or the inadvertent blockage of incoming airflow. For example, the protective grille 5172 may define a plurality of pores 5173 along its length or course. At least a portion of the pores 5173 may function as inlets for air drawn into the aerosol-generating device 5100. The outlet 6110 may be in communication with the plurality of pores 5173, such that during generation of an aerosol, air can flow into the aerosol-generating device 5100 via the plurality of pores 5173 of the protective grille 5172 through the outlet 6110 of the charging structure 5170 and into the air passage 5720 via the inlet 5175 to the capsule (e.g., capsule 200).
Like the protective grille 172, each of the pores 5173 may have an oval or circular shape, although not limited thereto. In at least one example embodiment, the protective grille 5172 may include an approved food contact material. For example, the protective grille 5172 may include plastic, metal (e.g., stainless steel, aluminum), or any combination thereof. In at least one example embodiment, a surface of the protective grille 5172 may be coated, for example with a thin layer of plastic, and/or anodized. In at least one example embodiment, the charging connector assembly 5169 may further include a locking clip 5180 that holds the protective grille 172 to the charging structure 5170. The locking clip 5180 may help to preserve the air flow through the charging connector assembly 5169 to the air passage 5720 and may also eliminate the need for bonding or other mechanical attachment of the protective grille 172 to the charging connector 5170.
In at least one example embodiment, as shown in
In at least one example embodiment, the replaceable mouthpiece 5190 includes a first end 5192 and a second end 5194 distal from the first end 5192. The replaceable mouthpiece 5190 tapers between the first end 5192 and the second end 5194. In at least one example embodiment, a diameter or average length/width dimensions of the first end 5192 may be smaller than a diameter or average length/width dimensions of the second end 5194. At the first end 5192, the tapered area may have a slight inward curvature 5191 that is configured to receive the lips of an adult consumer so as to improve the comfort and experience. Also like the replaceable mouthpiece 190, the first end 5192 of the replaceable mouthpiece 5190 has an oblong or elliptical shape and includes one or more outlets 5196. However, different from the replaceable mouthpiece 190, the outlets 5196 of the replaceable mouthpiece 5190 are aligned to form a linear line or zone, where each of the one or more outlets 5196 is generally oval or oblong. In other example embodiments, the replaceable mouthpiece 5190 may include fewer or more outlets 5196. Further, the outlets 5196 may be round, oval, square, rectangular, or any other shape.
In at least one example embodiment, the mouthpiece retention mechanism 6900 is a snap-fit mechanism that allows an adult consumer to position and retain the replaceable mouthpiece 5190 within the lid 5110 of the aerosol-generating device 5100. In other example embodiments, the mouthpiece retention mechanism 6900 may include a friction fit, threading, or any other suitable retention mechanism that allows an adult consumer to releasably secure the replaceable mouthpiece 5190 within the lid 5110.

In at least one example embodiment, ss illustrated, the mouthpiece seal 5875 defines a channel 7100 that at least partially aligns with a mouthpiece channel 7110 defined by the replaceable mouthpiece 5190. The channel 7100 and the mouthpiece channel 7110 are in fluid communication with and/or lead to the outlet(s) 5196 of the replaceable mouthpiece 5190. In at least one example embodiment, as shown in
In at least one example embodiment, the mouthpiece seal 5875 may include, on a surface facing away from the replaceable mouthpiece 5190 and for contacting the capsule (e.g., capsule 200), one or more bevels 5878 that are configured to apply a substantially centralized and uniform downward force to a capsule (e.g., capsule 200) in the capsule-receiving cavity 5133. For example, the one or more bevels 5878 may form one or more rounded projections that extend around a centralized opening or inlet 5195. In this manner, as best illustrated in
A number of non-limiting examples of different capsules are disclosed herein. It should be understood that the relevant teachings/variants with regard to one capsule may be applicable to the other capsules unless indicated otherwise. In addition, although the aerosol-generating device 100 and the aerosol-generating device 500 and the aerosol-generating device 5100 are disclosed as being configured to receive and heat the capsule 200, it should be understood that the aerosol-generating device 100 and/or the aerosol-generating device 500 and/or the aerosol-generating device 5100 may also be configured to receive and heat the capsule 1200, the capsule 1300, the capsule 1400, the capsule 1500, the capsule 1600, and the capsule 1700 as well as variants thereof. Further, any portion or feature of each of the aerosol-generating device 100, the aerosol-generating device 500, and/or the aerosol-generating device 5100 may be substituted in other ones of the aerosol-generating device 100, the aerosol-generating device 500, and/or the aerosol-generating device 5100 as desired.
