Description

[Technical Field]

[0001] At least some exemplary embodiments relate to aerosol generating devices, such as heat-not-burn (HNB) aerosol generating devices configured to generate aerosols without substantial thermal decomposition of the aerosol-forming substrate, and more particularly to charging systems for aerosol generating devices, such as, but not limited to, heat-not-burn (HNB) aerosol generating devices. [Background technology]

[0002] Some electronic devices are configured to heat plant material to a temperature sufficient to release components of the plant material while maintaining the temperature below the plant material's combustion point (or ignition temperature) to avoid substantial thermal decomposition (e.g., self-sustaining or self-sustaining combustion) of the plant material. Such devices may be referred to as aerosol-generating devices (e.g., thermal non-combustion aerosol-generating devices and / or thermal non-combustion devices), and the heated plant material may be tobacco and / or cannabis. In some cases, the plant material may be introduced directly into the heating chamber of the aerosol-generating device. In other embodiments, the plant material may be pre-packaged in individual containers for easy insertion and removal from the aerosol-generating device. Summary of the Invention

[0036] Several detailed exemplary embodiments are disclosed herein. However, the specific structural and functional details disclosed herein are merely representative for purposes of describing the exemplary embodiments. However, the exemplary embodiments may be embodied in many alternative forms and should not be construed as limited to only the exemplary embodiments set forth herein.

[0037] Accordingly, while exemplary embodiments are susceptible to various modifications and alternative forms, exemplary embodiments thereof are shown by way of example in the drawings and will be described in detail herein. It should be understood, however, that there is no intention to limit the exemplary embodiments to the particular forms disclosed, but on the contrary, the exemplary embodiments are intended to cover all modifications, equivalents, and alternatives falling within the scope of the exemplary embodiments. Like numbers refer to like elements throughout the description of the figures.

[0038] When an element or layer is referred to as being "on," "connected," "coupled," or "overlying" another element or layer, it is understood that it can be directly connected to, coupled to, or overlying the other element or layer, or that intervening elements or layers may be present. In contrast, when an element is referred to as being "directly resting on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers present. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] It should be understood that terms such as "first," "second," and "third" are used to distinguish between elements and do not denote any order or importance. Although terms such as "first," "second," and "third" 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 used only to distinguish one element, region, layer, or section from another region, layer, or section. Thus, a first element, component, region, layer, or section described below can be referred to as a second element, region, layer, or section without departing from the teachings of the exemplary embodiments.

[0040] For convenience of description, spatially relative terms (e.g., "below," "below," "down," "above," "above," etc.) may be used herein to describe the relationship of one element or feature to another element or feature as shown 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 were turned over, elements described as being "below" or "below" other elements or features would now be oriented "above" the other elements or features. Thus, the term "below" can encompass both an orientation of above and below. The device may be in other orientations (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0041] The terminology used herein is for the purpose of describing various exemplary embodiments only and is not intended to limit the exemplary embodiments. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will be further understood that the terms "comprise," "include," "comprise," "comprises," and / or "consisting of" specify the presence of stated features, integers, steps, operations, and / or elements, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or groups thereof.

[0042] When the terms "about" or "substantially" are used in connection with numerical values ​​herein, it is intended that the associated numerical values ​​include manufacturing or operational tolerances (e.g., ±10%) around the stated numerical values. Furthermore, when the terms "generally" or "substantially" are used in connection with geometric shapes, it is intended that precision in the geometric shapes is not required, but that freedom in the shapes is within the scope of the present disclosure. Furthermore, whether a numerical value or shape is modified as "about," "generally," or "substantially," it will be understood that the numerical value or shape should be interpreted as including manufacturing or operational tolerances (e.g., ±10%) around the stated numerical value or shape.

[0043] 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 the exemplary embodiments belong. Furthermore, terms, including those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined as such in this specification.

[0044] As used herein, "bonded" includes both removably bonded and permanently bonded. For example, if an elastic layer and a support layer are removably bonded to one another, the elastic layer and the support layer can be separated when sufficient force is applied.

[0045] Hardware may include, but is not limited to, one or more processors, one or more central processing units (CPUs), one or more microcontrollers, one or more arithmetic logic units (ALUs), one or more digital signal processors (DSPs), one or more microcomputers, one or more field programmable gate arrays (FPGAs), one or more systems on a chip (SoCs), one or more programmable logic units (PLUs), one or more microprocessors, one or more application specific integrated circuits (ASICs), or any other device or apparatus that can respond to and execute instructions in a defined manner.

[0046] 1-3 are illustrations of an aerosol generating device (e.g., a heat-not-burn (HNB) aerosol generating device) according to at least one exemplary embodiment. For example, FIG. 1 is a top perspective view of the aerosol generating device 100 including a housing 102 and a lid 104, where the lid 104 is in a closed position relative to the housing 102. FIG. 2 is another top perspective view of the aerosol generating device 100, where the lid 104 is open relative to the housing 102 and the capsule 200 is received by a capsule receiving portion 212 defined in the housing 102. FIG. 3 is a bottom perspective view of the aerosol generating device 100, where the lid 104 is in a closed position relative to the housing 102. FIG. 4 is a view from below of the aerosol generating device 100, where the lid 104 is in a closed position relative to the housing 102.

[0047] In some exemplary embodiments, as best shown in FIG. 1 , the aerosol generating device 100 has a generally oval, rectangular, or pebble shape. The aerosol generating device 100 may include a housing 102 and a lid 104 (which may also be referred to as a door) configured to open and close relative to the housing 102 (e.g., compare FIG. 1 with FIG. 2 ). The housing 102 may have a first end (or bottom) 106 and a second end (or top) 108 opposite the first end 106. The lid may have a first end 110 and a second end 112 opposite the first end 110. The first end 110 of the lid 104 may be fixedly coupled to the second end 108 of the housing 102 in a first position 114 and releasably coupled to the second end 108 of the housing 102 in a second position 116. The first location 114 of the housing 102 may be on a first side 118 of the aerosol generation device 100. The second location 116 of the housing 102 may be on a second side 120 of the aerosol generation device 100.

[0048] In some exemplary embodiments, the lid 104 may be fixedly coupled to the housing 102 at the first position 114 by a hinge 202 or other similar connector that allows the lid 104 to move (e.g., swing and rotate) from an open position (see FIG. 2 ) to a closed position (see FIG. 1 ). In some exemplary embodiments, the hinge 202 may be a torsion spring. In some exemplary embodiments, the housing 102 may include a recess 204 at the first position 114. The recess 204 may be configured to receive a portion of the lid 104 to allow easy and smooth movement of the lid 104 from the open position to the closed position (and vice versa). The recess 204 may have a structure that corresponds to a corresponding portion of the lid 104. For example, as shown, the recess 204 may include a substantially curved portion 206 having a generally concave shape that corresponds to the curvature of the lid 104, which has a generally convex shape.

[0049] In some exemplary embodiments, the lid 104 may be releasably coupleable to the housing 102 in the second position 116 by a latch 208, or other similar connector, that secures (or secures) the lid 104 in a closed position and is easily releasable so that the lid 104 can be moved from the closed position (see FIG. 1 ) to an open position (see FIG. 2 ). In some exemplary embodiments, the latch 208 may be coupled to an unlatching mechanism (not shown) disposed within the housing 102. The unlatching mechanism may be configured to move the latch 208 from a first position (or closed position) (see FIG. 1 ) to a second position (or open position) (see FIG. 2 ).

[0050] In some exemplary embodiments, the aerosol generating device 100 may include a mouthpiece 122 extending from a body of the aerosol generating device 100. The mouthpiece 122 may be coupled to the lid 104. For example, the mouthpiece 122 may include a first end 124 and a second end 126 opposite the first end 124. The second end 126 of the mouthpiece 122 may be coupled to the second end 112 of the lid 104. For example, in some exemplary embodiments, the second end 126 of the mouthpiece 122 may be releasably coupled to the second end 112 of the lid 104.

[0051] In some exemplary embodiments, as shown, the mouthpiece 122 may be tapered between the first end 124 and the second end 126. For example, the diameter or average length / width dimension of the first end 124 may be smaller than the diameter or average length / width dimension of the second end 126. Toward the first end 124, the taper may have a slight inward curvature 128 configured to receive the lips of an adult consumer and improve comfort and experience. In some exemplary embodiments, the first end 124 has an oval or elliptical shape and may include one or more outlets 130. For example, the first end 124 may include four outlets 130 so that four or more different regions or quadrants of an adult consumer's mouth can be engaged during use of the device 100. In other embodiments, the mouthpiece 122 may have fewer or more than four outlets 130.

[0052] In some exemplary embodiments, the housing 102 may include a consumer interface panel 132 disposed on the second side 120 of the aerosol generating device 100. For example, the consumer interface panel 132 may be an oval-shaped panel that runs along the second side 120 of the device 100. The consumer interface panel 132 may include an unlatch button 134, as well as a communication (or display) screen 136 and / or control buttons 138. For example, in some exemplary embodiments, the consumer interface panel 132 may include a communication screen 136 disposed between the unlatch button 134 and the control buttons 138.

[0053] In some exemplary embodiments, communication screen 136 may be a user interface such as a human-machine interface (HMI) display. In at least one exemplary embodiment, communication screen 136 may be an integrated thin film transistor ("TFT") screen. In other exemplary embodiments, communication screen 136 is an organic light-emitting diode ("OLED") or light-emitting diode ("LED") screen. In each example, communication screen 136 may be configured for adult consumer engagement and have a generally rectangular shape.

[0054] In some exemplary embodiments, as shown, the unlatch button 134 may be located toward the second end 108 of the device 100, and the control button 138 may be located toward the first end 106 of the device 100. The unlatch button 134 and the control button 138 may be adult consumer interaction buttons. For example, the control button 138 may turn the aerosol generation device 100 on or off. The unlatch button 134 may be configured to activate an unlatch mechanism configured to move the latch 208 from a first position (or closed or locked position) to a second position (or open position), as described in further detail below.

[0055] In some exemplary embodiments, the unlatch button 134 and / or the control button 138 can have a substantially circular shape with a central depression or indentation configured to direct pressure applied by an adult consumer, although exemplary embodiments are not limited thereto. While only two buttons are shown, it should be understood that more or fewer buttons may be provided depending on the available functionality and desired adult consumer interface and aerosol generation device 100.

[0056] As shown in FIG. 2 , when the lid 104 is in an open position, a capsule receiving cavity 210 in the housing 102 may be exposed. A capsule connector 212 may define the capsule receiving cavity 210 in the housing 102. In some exemplary embodiments, the capsule connector 212 may be attached to or otherwise secured to a printed circuit board (PCB) within the housing 102. In some exemplary embodiments, a capsule 214 may be received by the capsule receiving cavity 210, as shown in FIG. 2 . In some exemplary embodiments, a gasket (not shown) may be disposed around the capsule 214 to help secure the capsule 214 in place within the housing 102.

[0057] In some exemplary embodiments, as shown, the capsule 214 may include a housing 216 configured to contain an aerosol-forming substrate and a heater (e.g., an electric heater). In some exemplary embodiments, the housing 216 may be in the form of a cover, such as a shell or a box sleeve. In some exemplary embodiments, the capsule 214 may include a first end cap 217 defining (or disposed on) a first (or upper) end of the capsule 214 and a second end cap (not shown) defining (or disposed on) a second (or lower) end of the capsule 214 opposite (or remote from) the first end. For example, the second end cap may face the first end cap 217 such that the second end cap is disposed within the housing 102 when the capsule 214 is received by the capsule-receiving cavity 210. In some exemplary embodiments, the first end cap 217 may include a first opening 218. In other exemplary embodiments, first opening 218 may be a series of openings disposed through first end cap 217. Similarly, in some exemplary embodiments, second end cap may include a second opening or series of openings. In some exemplary embodiments, first end cap 217 and / or second end cap may be transparent to function as a window configured to allow viewing of the contents / components (e.g., aerosol-forming substrate and / or heater) within capsule 214.

[0058] In some exemplary embodiments, the aerosol-forming substrate can be a material or combination of materials capable of producing an aerosol. The aerosol is generated (or output) by the aerosol-generating device disclosed, claimed, and equivalents thereof. The material can include a compound (e.g., nicotine, cannabinoid), and when the material is heated, an aerosol containing the compound is generated. The heating can be below combustion temperatures to generate the aerosol without substantial thermal decomposition of the aerosol-forming substrate or substantial generation of combustion by-products (if any). Thus, in some exemplary embodiments, no thermal decomposition occurs during heating and the resulting generation of the aerosol. In other exemplary embodiments, thermal decomposition and combustion by-products may be present, but are considered to be relatively minor and / or merely incidental.

[0059] In some exemplary embodiments, the aerosol-forming substrate may be a fibrous material. For example, the fibrous material may be a plant material. The fibrous material is configured to release a compound when heated. The compound may be a component naturally occurring in the fibrous material. For example, the fibrous material is a plant material such as tobacco, and the released compound is nicotine. The term "tobacco" includes any tobacco plant material, including tobacco leaf, tobacco plugs, reconstituted tobacco, compressed tobacco, extruded tobacco, powdered tobacco, and combinations thereof from one or more tobacco plants, such as Nicotiana rustica and Nicotiana tabacum.

[0060] In some exemplary embodiments, the tobacco material can include material from any member of the Nicotiana genus. Furthermore, the tobacco raw material can also include a blend of two or more different tobacco varieties. Suitable types of tobacco raw materials that can 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 can be provided in any suitable form, including, but not limited to, tobacco lamina, processed tobacco material, processed tobacco stems, such as cut rolled stems and cut puffed stems, such as expanded tobacco and puffed tobacco, reconstituted tobacco material, blends thereof, and the like. In some exemplary embodiments, the tobacco material is in the form of a substantially dried mass of tobacco. Furthermore, in some embodiments, the tobacco material can be mixed and / or combined with at least one of propylene glycol, glycerin, subcombinations thereof, or combinations thereof.

[0061] In some exemplary embodiments, the compound may also be a naturally occurring component of a medicinal plant with medically recognized therapeutic effects. For example, the medicinal plant may be the cannabis plant, and the compound may be a cannabinoid. Cannabinoids interact with receptors in the body to produce a variety of effects. As a result, cannabinoids have been used for a variety of medicinal purposes, including the treatment of pain, nausea, epilepsy, and psychiatric disorders. The fibrous material may include leaf and / or flower material from one or more cannabis species, such as Cannabis sativa, Cannabis indica, and Cannabis ruderalis. In some embodiments, the fibrous material is a mixture of 60-80% (e.g., 70%) Cannabis sativa and 20-40% (e.g., 30%) Cannabis indica.

[0062] 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 to tetrahydrocannabinol (THC), and cannabidiolic acid (CBDA) is a precursor to cannabidiol (CBD). Tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) can be converted to tetrahydrocannabinol (THC) and cannabidiol (CBD), respectively, by heating. In an exemplary embodiment, heat from a heater can cause decarboxylation to convert tetrahydrocannabinolic acid (THCA) in the capsule to tetrahydrocannabinol (THC) and / or cannabidiol acid (CBDA) in the capsule to cannabidiol (CBD).

[0063] When both tetrahydrocannabinolic acid (THCA) and tetrahydrocannabinol (THC) are present in the capsule, decarboxylation and the resulting conversion result in a decrease in tetrahydrocannabinolic acid (THCA) and an increase in tetrahydrocannabinol (THC). At least 50% (e.g., at least 87%) of tetrahydrocannabinolic acid (THCA) may be converted to tetrahydrocannabinol (THC) during heating of the capsule. Similarly, when both cannabidiolic acid (CBDA) and cannabidiol (CBD) are present in the capsule, decarboxylation and the resulting conversion result in a decrease in cannabidiolic acid (CBDA) and an increase in cannabidiol (CBD). At least 50% (e.g., at least 87%) of cannabidiolic acid (CBDA) may be converted to cannabidiol (CBD) during heating of the capsule.

[0064] In some exemplary embodiments, the compound may be or may additionally include a non-naturally occurring additive subsequently introduced into the fibrous material. In one example, the fibrous material may comprise at least one of cotton, polyethylene, polyester, rayon, combinations thereof, and the like (e.g., in the form of gauze). In another example, the fibrous material may be a cellulosic material (e.g., a non-tobacco and / or non-cannabis material). In either example, the introduced compound may comprise nicotine, a cannabinoid, and / or a flavoring. The flavoring may be naturally derived, such as a plant extract (e.g., tobacco extract, cannabis extract), and / or artificially derived. In yet another example, when the fibrous material comprises tobacco and / or cannabis, the compound may be or may additionally comprise one or more flavorings (e.g., menthol, mint, vanilla). Thus, the compound within the aerosol-forming substrate may comprise naturally occurring components and / or non-naturally occurring additives. In this regard, it should be understood that the existing levels of naturally occurring components in the aerosol-forming substrate may be increased by supplementation. For example, the amount of nicotine in tobacco can be increased by supplementing it with an extract containing nicotine. Similarly, the existing levels of one or more cannabinoids in a quantity of cannabis can be increased by supplementing it with an extract containing such cannabinoids.

[0065] In some exemplary embodiments, the capsule receiving cavity 210 may have a base that may be disposed within the housing 102. In some exemplary embodiments, the base may include at least one contact point that may be configured to couple with one or more contact points of the capsule 214 when the capsule 214 is received by the capsule receiving cavity 210. When the capsule 214 is inserted into the capsule receiving cavity 210, the weight of the capsule 214 itself may not be sufficient to compress the at least one contact point on the base of the capsule receiving cavity 210. As a result, the capsule 214 may simply rest on the exposed pin of the at least one contact without compressing (or significantly compressing) the electrical contact of the at least one contact. In some exemplary embodiments, the weight of the lid 104 itself may not compress the electrical contact of the at least one contact to a significant extent when pivoted to the closed position, and instead may simply rest on the capsule 214 in an intermediate, partially open / closed position. In such embodiments, to close the lid 104, a deliberate motion (e.g., a downward force) should be applied to the lid 104, causing the inward-facing surface 220 of the lid 104 to depress against the capsule 214 to provide the desired seal and also compress the capsule 214, thus fully engaging the electrical contacts of at least one of the contacts. In some exemplary embodiments, full closure of the lid 104 may also result in engagement with the latch 208, which may maintain the closed position and the desired mechanical / electrical engagement involving the capsule 214 until released (e.g., via the unlatch button 134). The force required to close the lid 104 may help to ensure and / or improve the air / aerosol seal, provide a more robust electrical connection, and may also help improve device and thermal efficiency and battery life by reducing or eliminating initial power consumption and / or parasitic heating of the capsule 214.

[0066] In some exemplary embodiments, the lid 104 may include an internal cavity 222 that may be adapted to receive the housing 102 when the lid is in the closed position. In some embodiments, the internal cavity 222 of the lid 104 may include an abutment or engagement member or surface 220 configured to engage the capsule 214 when the lid 104 is rotated to the closed position. The surface 220 of the lid 104 may include a recess that may correspond to the size and shape of the capsule and / or a resilient material to strengthen the interface with the capsule to provide a desired seal. In some exemplary embodiments, the lid 104 may further include an opening 224 that may be adapted to receive the second end 126 of the mouthpiece 122. The mouthpiece 122 may include at least one extension 226 that may be received by the opening 224 of the lid 104 to secure the mouthpiece 122 to the lid 104. In some exemplary embodiments, the lid 104 may further include a protrusion (not shown) that may be configured to mate with a recess 228 of the housing 102. The protrusion may fit within the recess 228 when the lid 104 is coupled to the housing 102 in the closed position.

[0067] In some exemplary embodiments, the housing 102 defines a charging connector (or port) 170. For example, as best shown in FIG. 3 , the charging connector 170 may be defined / located at the bottom (or first) end 105 of the housing 120 distal from the capsule receiving cavity 210. The charging connector 170 may be configured to receive current from an external power source (e.g., via a USB / mini-USB cable) to charge a power source internal to the aerosol generating device 100. The power source may include one or more batteries, such as a rechargeable dual battery, a lithium-ion battery, a fuel cell, or the like. In some exemplary embodiments, the charging connector 170 may also be configured to transmit data to and / or receive data (e.g., via a USB / mini-USB cable) from another aerosol generating device (e.g., a heat-not-burn (HNB) aerosol generating device) and / or other electronic devices (e.g., a phone, a tablet, a computer, etc.). In some exemplary embodiments, the aerosol generating device 100 may alternatively or additionally be configured to communicate wirelessly (e.g., via Bluetooth®) with such other aerosol generating devices and / or electronic devices.

[0068] In some exemplary embodiments, as best shown in FIG. 4 , charging connector 170 may be an assembly defining cavity 171 with protrusions 175 within cavity 171. In some exemplary embodiments, protrusions 175 do not extend beyond the edges of cavity 171. In some exemplary embodiments, charging connector 170 includes a protective grill 172 surrounding at least a portion of cavity 171. As shown, protective grill 172 may have an annular configuration surrounding cavity 171. Protective grill 172 may be configured to help reduce or prevent the intrusion of debris and / or the inadvertent blockage of incoming airflow. For example, protective grill 172 may define multiple holes 173 along its length or course. For example, holes 173 may also be arranged around cavity 171 (e.g., in a serial arrangement). Each hole 173 may have, without limitation, an oval or circular shape.

[0069] In some exemplary embodiments, the holes 173 in the protective grill 172 can function as inlets for air to be drawn into the aerosol generating device 100. During operation of the aerosol generating device 100, ambient air entering through the holes 173 in the protective grill 172 can converge to form a combined flow that travels to the capsule 200. For example, the holes 173 can be in fluid communication with the capsule receiving cavity 210. In some exemplary embodiments, air can be drawn from the holes 173 through the capsule receiving cavity 130. For example, air can be drawn through the capsule 200 received by the capsule receiving cavity 210 and out of the mouthpiece 122.

[0070] In some exemplary embodiments, the protective grill 172 may comprise an approved food contact material. For example, the protective grill 172 may comprise plastic, metal (e.g., stainless steel, aluminum), or any combination thereof. In some exemplary embodiments, the surface of the protective grill 172 may be coated with a thin layer of plastic and / or anodized. In some exemplary embodiments, the exterior of the housing 102 and / or lid 104 may be formed from metal (such as aluminum, stainless steel, and / or the like), aesthetic, food contact-rated plastic (such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystal polymer (LCP), copolyester plastic, and / or any other suitable polymer and / or plastic), or any combination thereof. In some exemplary embodiments, mouthpiece 122 may likewise be formed from metal (such as aluminum, stainless steel, and / or the like); aesthetically pleasing, food-contact rated plastic (such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS) material, liquid crystal polymer (LCP), copolyester plastic, and / or any other suitable polymer and / or plastic); plant-based material (wood, bamboo, etc.); or any combination thereof. In some exemplary embodiments, one or more interior surfaces of housing 102 and / or lid 104 may be formed from or coated with a high-temperature plastic (e.g., polyetheretherketone (PEEK), liquid crystal polymer (LCP), and / or the like).

[0071] It should be understood that device 100 and capsule 214 are incorporated herein by reference in their entirety, as set forth in Atty. Docket No. 24000NV-000847-US, entitled "HEAT-NOT-BURN (HNB) AEROSOL-GENERATING DEVICES AND CAPSULES," filed on the same day, Application No. XX / XXX,XXX.

[0072] FIG. 5 is a block diagram illustrating an exemplary charging system 500 for use with an aerosol generating device, such as the aerosol generating device 100 illustrated in FIGS. 1-4. The charging system 500 can be used to accommodate multiple usage scenarios, such as when a charging device (e.g., a charger or charging cable) is connected to (or received by) the charging connector (or port) 170 and when charging is in progress using the charging device connected to (or received by) the charging connector (or port) 170. In some exemplary embodiments, the multiple usage scenarios include, for example, a first (or disabled) mode, a second (or intra-session) mode, and a third (or inter-session) mode. The first mode describes a state when (or indicates) use of the aerosol generating device 100 is unavailable (or not permitted) while a charging device is connected to (or received by) the charging connector (or port) 170. The second mode describes a state when charging of the aerosol generation device 100 is in progress (e.g., the charging connector (or port) 170 is in communication with a charging device), but the aerosol generation device 100 may be used (e.g., aerosol is generated). The second mode describes a state when the aerosol generation device 100 can be charged between and / or during an aerosol generation session. The third mode describes a state when the aerosol generation device 100 may be used (e.g., aerosol is generated) but only when charging is paused (or stopped) when a charging device is connected to (or received by) the charging connector (or port) 170. In the third mode, charging occurs only when the aerosol generation device 100 is not in use (i.e., when the aerosol generation device 100 is not actively being used for heating). The third mode describes a state in which the aerosol generating device 100 can be (or indicates) charged only for the duration of the aerosol generating session.In some exemplary embodiments, the selection of a particular mode (i.e., the first mode as opposed to the second mode or the third mode, the second mode as opposed to the third mode, etc.) may be a pre-selected factory setting.

[0073] In some exemplary embodiments, charging system 500 includes a processor 502, a charger detection (or connection) circuit 510, a heating engine control 520, a battery charger 530, a battery monitoring system (or battery voltage / current measurement circuit) 540, a battery temperature measurement circuit 550, and a memory 560, as well as control buttons 138 and communication screen 136. For example, processor 502 can be in communication with charger detection circuit 510, a heating engine control 520, a battery charger 530, a battery monitoring system 540, a battery temperature measurement circuit 550, and a memory 560, as well as control buttons 138 and communication screen 136. In some exemplary embodiments, processor 502 includes a multi-channel analog-to-digital converter (ADC) 504 and / or an inter-integrated circuit (I2C) interface 506. Battery monitoring system 540 can be in communication with multi-channel analog-to-digital converter (ADC) 504 and inter-integrated circuit (I2C) interface 506. The battery temperature measurement circuit 550 can be in communication with a multi-channel analog-to-digital converter (ADC) 504 .

[0074] In some exemplary embodiments, processor 502 includes hardware including logic circuits, a hardware / software combination that can be configured to execute software, or any combination thereof. For example, processor 502 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, an application-specific integrated circuit (ASIC), or other similar devices. In some exemplary embodiments, processor 502 is configured as a special-purpose machine (e.g., a processing unit) designed to execute software (or instructions) stored, for example, in memory 560. In some exemplary embodiments, the software (or instructions) may be embodied as program code including instructions for performing and / or controlling any or all of the operations described herein as being performed by processor 502. In some exemplary embodiments, processor 502 may include other processing or control circuitry.

[0075] In some exemplary embodiments, the charger detection circuit 510 may be configured to generate a signal indicating that the aerosol generation device 100 has been connected to or removed from a charging device (e.g., a charger or charging cable, such as a USB cable). FIG. 8 illustrates an example embodiment of the charger detection circuit 510. In some exemplary embodiments, the charger detection circuit 510 includes a detection line 802 and a voltage divider. The voltage divider may include resistors 805 and 810. The resistors 805 and 810 may be connected in series. A first end of the first resistor 805 is connected to the detection line 802, and a second end of the first resistor 805 is connected to a first end of the second resistor 810 and to an output 820. The output 820 may be connected to / provided to the processor 802. A second end of the second resistor 810 may be connected to ground. When a charging device is connected to the aerosol generating device 100, the charging device supplies a voltage (e.g., VBus, 5V) to the detection line 802, which may be divided by resistors 805 and 810. A detection signal USB_present is output at output 820 and provided to the processor 502.

[0076] In some exemplary embodiments, the processor 502 receives a signal indicating that the aerosol generating device 100 is connected to a charging device (and that other battery charging checks are satisfactory) and initiates the battery charging process.

[0077] In some exemplary embodiments, the heating engine control 520 may be configured to provide energy to a heater 522 disposed within the housing 216 that defines the capsule 214. In some exemplary embodiments, the processor 502 may determine the energy provided to the heater based on a selected mode of the charging system 500. For example, during a first (or disabled) mode, the processor 502 controls the heating engine control 520 so that energy is not provided to the heater while a charging device is detected; during a second (or intra-session) mode, the processor 502 controls the heating engine control 520 so that energy is provided to the heater during active charging; and during a third (or inter-session) mode, the processor 502 controls the heating engine control 520 so that energy is provided to the heater only when active charging is not occurring. In some exemplary embodiments, the heating engine control 520 may be as described in U.S. Application No. 17 / 151,406 (Atty. Dkt. No. 24000NV-000670-US).

In other exemplary embodiments, battery charger 530 may include a Linear Technologies LTC4095 battery charger chipset that includes a SUSP pin that can be used to enable or disable battery charger 530.

[0079] In some exemplary embodiments, the battery monitoring system (or battery voltage / current measurement circuit) 540 can be configured to measure key battery parameters. For example, the battery monitoring system 540 can provide battery voltage as a direct measurement using a voltage divider and battery current as a physical gas gauge chipset. In some exemplary embodiments, the battery monitoring system 540 can be configured to generate a signal indicating that the aerosol generation device 100 has entered a low-battery state. In some exemplary embodiments, when the processor 502 determines that the aerosol generation device 100 has entered a low-battery state, an ongoing session may be terminated. The battery monitoring system 312 can generate a signal indicating that the aerosol generation device 100 has entered a low-battery state when the power supply 532 reaches a charge below a threshold indicating that the aerosol generation device 100 is in a low-battery state and cannot continue to operate until it is connected to a charging device and / or recharged, depending on the mode of the charging system 500.

[0080] FIG. 9 shows an exemplary embodiment of a battery voltage circuit 540A. In some exemplary embodiments, the battery voltage circuit 540A includes a resistor R47, an enable control transistor Q5, a resistor R43, a battery transistor Q5B, resistors R46 and R48, and a capacitor C25. A first terminal of the resistor R47 and a gate of the transistor Q5 may be connected to a battery voltage enable input BATT_VOL_EN.

The first end of resistor R3 is connected to the ground terminal of chip U1, and the second end of resistor R3 is connected to the chip select not (CSN) terminal. The positive terminal of a power source (such as a battery) can be connected to the "Batt" signal (e.g., connected to the BATT pin of the gauge chip). In some exemplary embodiments, the battery current can be read from the gas gauge via an I2C interface.

[0082] In some exemplary embodiments, battery temperature measurement circuit 550 may be a thermistor measurement circuit in which a thermistor is located near power source 532. In some exemplary embodiments, battery temperature measurement circuit 550 may be a thermistor measurement circuit in which a thermistor is located near power source 532.

[0083] In some exemplary embodiments, the multi-channel analog-to-digital converter (ADC) 504 may be configured to convert analog voltage measurements from the battery measurement voltage / current measurement circuit 540 and the battery temperature measurement circuit 550 into digital power supply (e.g., battery) voltage measurements and / or power supply (e.g., battery) temperature measurements. In some exemplary embodiments, the power supply (e.g., battery) voltage may be read directly from the battery voltage using a potential divider to match the dynamic range to the measurement range of the analog-to-digital converter (ADC) 504. In some exemplary embodiments, power supply (e.g., battery) temperature measurements may be made using a thermistor measurement circuit located proximate to the surface of the power supply 532.

[0084] In some exemplary embodiments, the Inter-Integrated Circuit (I2C) interface 506 is a standard serial communications module configured to read power supply (e.g., battery) current measurements from a hardware gas gauge chipset via a register interface.

[0085] In some demonstrative embodiments, memory 560 may represent any of the terms "storage medium," "computer-readable storage medium," or "non-transitory computer-readable storage medium," and may represent one or more devices for storing data, including, for example, read-only memory (ROM), random-access memory (RAM), magnetic RAM, core memory, magnetic disk storage media, optical storage media, flash memory devices, and / or other tangible machine-readable media for storing information. The term "computer-readable medium" may include, but is not limited to, portable or permanent storage devices, optical storage devices, and various other media capable of storing, storing, or transporting instructions and / or data.

[0086] In some exemplary embodiments, the control button 138 may be configured to generate a signal indicating that an adult consumer has switched the aerosol generating device 100 to an “off” state, ending a session (e.g., an aerosol generating event) of the device 100.

[0087] In some exemplary embodiments, the communication screen 136 may be configured to display information related to the aerosol generation device 100. The communication screen 136 may be configured to display one or more icons to communicate information related to the aerosol generation device 100. For example, in some exemplary embodiments, the communication screen 136 may be configured to display a charging iconography to an adult consumer. In some exemplary embodiments, the communication screen 136 may be configured to display two icons. For example, in some exemplary embodiments, the communication screen 136 may be configured to display a symbol or icon (e.g., a "lightning bolt" modified icon) near the current capsule progress indicator to indicate to the adult consumer that the charging device is active, while still communicating a session progress indicator.

[0088] In some exemplary embodiments, the icons displayed on communication screen 136 may be generally referred to as system icons. System icons may have a variety of colors, shades, and / or sizes. Figures 6A-6I show different embodiments of icons that may be displayed by communication screen 136.

[0089] For example, FIG. 6A shows an example of a communication screen 136 that includes a capsule icon 137. The capsule icon 137 may include an oval (or oblong) shape that includes a superimposed shape, such as an arrow within a circle, as shown. The communication screen 136 may also include a modifier icon 139 located near (e.g., above) the capsule icon 137. In some exemplary embodiments, the modifier icon 139 may be a lightning bolt. The capsule icons 137 and 139 may together indicate that the aerosol generation device 100 is connected to a charging device during use.

[0090] For example, FIG. 6B shows an example of a communication screen 136 that includes a timer icon 402. In some exemplary embodiments, the timer icon 402 can indicate to an adult consumer the time remaining on the cool-down timer so that the consumer knows when the capsule 214 can be removed from the aerosol generating device 100. The timer icon 402 may be updated during the cool-down time to keep the consumer informed of when the capsule 214 can be removed from the aerosol generating device 100. For example, when 90% of the time remains on the cool-down timer, the timer icon 402 appears substantially as shown in FIG. 4A with approximately 90% of the thermometer filled or shaded. Once the cool-down time has elapsed, the timer icon 402 is updated so that the shaded portion of the thermometer corresponds to the remaining cool-down time on the cool-down timer.

[0091] 6C shows an example of a communication screen 136 that includes a warning icon 404. In some exemplary embodiments, the warning icon 404 can indicate to an adult consumer that the lid 104 of the aerosol generating device 100 was opened while the cool-down timer was running or while a session of the aerosol generating device 100 was running. The warning icon 404 can indicate to an adult consumer that the capsule 214 has not cooled to a comfortable temperature for removal from the aerosol generating device 100.

[0092] For example, 6D shows an example of a communication screen 136 that includes a capsule ejection icon 408. In some exemplary embodiments, the capsule ejection icon 408 can indicate to the adult consumer that the cool-down timer has expired and that the capsule 214 may be removed from the device 100.

[0093] 6E shows an example of a communication screen 136 that includes an end session icon 410. In some exemplary embodiments, the end session icon may indicate to an adult consumer that the capsule 214 is empty of aerosol-forming substrate. The end session icon 410 may indicate that a previously active session of the device 100 has ended. In some exemplary embodiments, the end session icon 410 may be displayed briefly on the communication screen 136 before the timer icon 402 is displayed.

[0094] 6F shows an example of a communication screen 136 that includes a first power off icon 412. In some exemplary embodiments, the first power off icon 412 can indicate to an adult consumer that the control button 138 is held down for at least three seconds while the cool-down timer is active. When the control button 138 is held down for at least three seconds, the aerosol generating device 100 can be powered off after the cool-down timer has elapsed. The first power off icon 412 can be displayed while the control button 138 is held down and while the second hold-off timer 328 is active.

[0095] 6G shows an example of the communications screen 136 including a second power off icon 413. In some exemplary embodiments, the second power off icon 413 may be displayed after the control button 138 is released and tapped a second time to confirm that the device 100 should be powered off. When the control button 138 is pressed a second time, the first power off icon 412 is removed from the communications screen 136 by the processor 502. The second power off icon 413 may be similar to the first power off icon 412, but the coloring of the icon may be reversed compared to the first power off icon 412. The second power off icon 413 is displayed while the second hold-off timer 328 is active and is removed from the communications screen 136 when the second hold-off timer expires.

[0096] 6H shows an example of a communication screen 136 including a cool-down recognition icon 414. In some exemplary embodiments, the cool-down recognition icon 414 can indicate to an adult consumer that the cool-down system 300 is still operating after the consumer presses the control button 138 to power off the aerosol generating device 100. More specifically, the cool-down recognition icon 414 may be displayed on the communication screen 136 after the second hold-off timer has elapsed and the first power-off icon 412 and the second power-off icon 413 have been removed from the communication screen 136. The cool-down recognition icon 414 is displayed until the cool-down timer 322 has elapsed.

[0097] 6I shows an example of a communication screen 136 that includes a fault icon 416. In some exemplary embodiments, the fault icon 416 can indicate to an adult consumer that the aerosol generating device 100 is in an inoperative state such that a session cannot be initiated. In some exemplary embodiments, the aerosol generating device 100 can be in an inoperative or faulty state when the lid 104 of the device 100 is closed after having been previously opened while a session is active or while the cool-down timer 322 is active.

[0098] FIG. 7 is a flowchart illustrating an example method 600 for controlling a charging system. Processor 503 may perform the method of FIG. 7. Processor 502 may initiate method 600 when a charging device (e.g., a charger or charger cable) event is detected. For example, processor 502 may receive one or more signals indicating that a state change event has occurred. Charger detection circuit 510 may initiate one or more signals indicating that a state change event has occurred. Processor 502 may continuously monitor charger detection circuit 510. In some exemplary embodiments, when processor 502 detects a state change, method 600 may proceed to conditional step 602, which determines whether one or more signals from charger detection circuit 510 indicate that a charging device has been connected to (e.g., inserted into) charging connector 170 or removed from contact with charging connector 170.

[0099] In some exemplary embodiments, if the processor 502 determines that the charging device has been removed from contact with the charging connector 170, the method 600 continues to step 604, where the charging system 500 shuts down the battery charger 530. The method 600 may then proceed to conditional step 606, where it is determined whether the capsule 214 has been received by the capsule receiving cavity 210. The charging system 500 may use an integrity check feature and / or a capsule detection switch to determine whether the capsule 214 has been received by the capsule receiving cavity 210. In some exemplary embodiments, the integrity check feature may be as described in U.S. Application No. ## / ###,### (Atty. Dkt. No. 24000NV-000932-US), entitled "CAPSULE MONITORING SYSTEM FOR AEROSOL-GENERATING DEVICE," filed on the same day, the entire contents of which are incorporated herein by reference.

[0100] In some exemplary embodiments, if the processor 502 determines that the capsule 214 is not present, the method 600 proceeds to step 614, where the processor instructs the communication screen 136 to display an icon representing the current charge level. For example, a standard "On" icon is displayed. In other exemplary embodiments, if the processor 502 determines that the capsule 214 is present, the method 600 continues to step 608, where the processor 502 instructs the communication screen 136 to remove the modifier icon (e.g., a "lightning bolt" modifier icon) as added in step 644, as described below. The method 600 may then proceed to step 610, where the processor 502 instructs the heating engine control 520 to provide energy to a heater disposed within the housing 216 that defines the capsule 214. The method 600 then proceeds to step 612, where the processor 502 displays a capsule icon (e.g., FIG. 6A ) on the communication screen 136.

[0101] In some exemplary embodiments, if processor 502 determines that a charging device is connected to charging connector 170, method 600 continues to step 620, where processor 503 causes charging system 500 to activate battery charger 530. In some exemplary embodiments, activating battery charger 530 may include initiating all system operations related to the charging process. Following step 620, method 600 may proceed to conditional step 622, where it is determined whether capsule 214 has been received by capsule receiving cavity 210 (as in conditional step 606). As described above, charging system 500 may use an integrity check function and / or a capsule detection switch to determine whether capsule 214 has been received by capsule receiving cavity 210.

[0102] In some exemplary embodiments, if the processor determines that the capsule 214 is not present, the method 600 continues to step 624, where the processor 502 instructs the communication screen 136 to display a charging indicator (e.g., a standard charging indicator). In other exemplary embodiments, if the processor 502 determines that the capsule 214 is present, the method 600 proceeds to step 630, where an in-use charging mode setting is received from the memory 560. The method 600 may then proceed to conditional step 632, where it is determined whether the in-use charging mode setting is the first mode (or a disabled mode).

[0103] In some exemplary embodiments, if processor 502 determines that the in-use charging mode setting is the first (or disabled) mode, method 600 may continue to step 634, where processor 502 instructs heating engine control 520 to terminate heating (or disable) (e.g., stop supplying energy to) a heater disposed within housing 216 defining capsule 214. Method 600 then proceeds to step 624, where processor 502 instructs communication screen 136 to display a charging indicator, as described above. In other exemplary embodiments, if processor 502 determines that the in-use charging mode setting is not the first (or disabled) mode, method 600 may continue to step 640, where (as in step 610) processor 502 instructs heating engine control 520 to supply energy to a heater disposed within housing 216 defining capsule 214. Thereafter, the method 600 may proceed to step 642, where the processor 502 may direct the communication screen 136 to display a capsule icon (eg, FIG. 6A).

[0104] In some demonstrative embodiments, after step 642, method 600 may continue to step 644, where processor 502 instructs communication screen 136 to display a symbol or icon (e.g., a "lightning bolt" modifier icon) near (e.g., on or above) the current capsule progress display (e.g., FIG. 6A ) to indicate to the adult consumer that the charging device is active while still communicating the session progress indicator. That is, the "lightning bolt" modifier icon indicates that a charging device is connected, but does not indicate that charging current is being supplied to power source 532.

[0105] In some exemplary embodiments, after step 644, method 600 may continue to conditional step 646, where it determines whether a session (e.g., an aerosol-generating event) is in progress. In some exemplary embodiments, if processor 502 determines that a session (e.g., an aerosol-generating event) is not in progress, method 600 may continue to step 650, where charging is enabled (e.g., charging system 500 activates battery charger 530). Method 600 then returns to step 644. In other exemplary embodiments, if processor 502 determines that a session (e.g., an aerosol-generating event) is in progress, method 600 may proceed to conditional step 648, where it determines whether the in-use charging mode setting is in the second (or intra-session) mode or the third (or inter-session) mode.

[0106] In some exemplary embodiments, if processor 502 determines that the in-use charging mode setting is the second (or intra-session) mode, method 600 continues to step 650, where processor 502 enables charging (e.g., charging system 500 activates battery charger 530). In some exemplary embodiments, enabling step 650 enables the charging current. Following step 650, method 600 returns to step 644, forming a continuous loop. In other exemplary embodiments, if processor 502 determines that the in-use charging mode setting is the third (or inter-session) mode, method 600 continues to step 652, where processor 502 instructs battery charger 530 to suspend charging for the session. In some exemplary embodiments, the processor instructs battery charger 530 to suspend the charging current.

[0107] After step 652, charging is re-enabled and method 600 returns to step 644, forming a continuous loop. In some exemplary embodiments, pausing and re-enabling charging does not start or stop the charging process, but rather suspends charging by setting the charging current to 0 mA, for example, by dedicating a "suspend" input on the charging device chipset.

[0108] In some exemplary embodiments, when processor 502 determines that a session is in progress (i.e., conditional step 646) and the second (or in-session) mode is active, a nearly fully charged power source may reach a fully charged state during the session (e.g., by reaching battery float voltage). In such a case, battery monitoring system (or battery voltage / current measurement circuitry) 540 automatically terminates the charging cycle regardless of the charging function in use. In such a case, the “lightning bolt” modifier icon may continue to be displayed by communication screen 136 because, as noted above, it indicates that a charging device is connected, but does not indicate that charging is in progress.

[0109] In some demonstrative embodiments, when processor 502 determines that a session is in progress (i.e., conditional step 646), the second (or in-session) mode is active, and the power source is being depleted by the heating energy used during the session, the energy usage causes the power source voltage to drop to a point where battery monitoring system (or battery voltage / current measurement circuitry) 540 restarts charging to "top up" the charge level.

[0110] In some demonstrative embodiments, processor 502 determines that a session is in progress (i.e., conditional step 646) and the second (or in-session) mode is active, and the flow of charging current to power source 532 may be reduced by an amount approximately equal to the current flowing to a heater disposed within housing 216 defining capsule 214. In such an example, the current from the charging circuit (i.e., from the charger) may bypass the power source, and processor 502 may use the current from the charging circuit to directly supply the heater.

[0111] The systems, devices, and methods described herein may provide significant advantages, such as the charging system 500 accommodating multiple use cases where it is impractical to physically disconnect the charging device from the aerosol generating device 100, and reducing time to use and heat buildup when a fully discharged aerosol generating device 100 is connected to the charging device.

[0112] The appended claims define novel and inventive aspects of the subject matter described above, but the claims may also encompass additional subject matter not specifically recited. For example, certain features, elements, or aspects may be omitted from the claims if they are not necessary to distinguish the novel and inventive features from those already known to those skilled in the art. Also, features, elements, and aspects described in the context of certain embodiments may be omitted, combined, or replaced with alternative features serving the same, equivalent, or similar purpose without departing from the scope of the invention as defined by the appended claims.
