[0059] Detailed Description

[0060] As used herein, the term "aerosol-generating material" refers to a material capable of generating an aerosol when exposed to energy, for example, by heating, irradiation, or other methods. Aerosol-generating materials may be in the form of, for example, a solid, liquid, or gel, and may or may not contain active ingredients and / or flavorings. Aerosol-generating materials may include plant-derived materials, such as tobacco-containing materials, including one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Aerosol-generating materials may also include other non-tobacco products, and may or may not contain nicotine, depending on the product. Aerosol-generating materials may be in the form of, for example, a solid, liquid, gel, wax, or the like. Aerosol-generating materials may also be a combination or blend of materials. Aerosol-generating materials are sometimes referred to as "smokable materials."

[0061] The aerosol-generating material may include a binder and an aerosolizing agent. Optionally, it may also include an active ingredient and / or a filler. Optionally, it may also include a solvent, such as water, in which one or more of the other components of the aerosol-generating material may or may not be soluble. In some embodiments, the aerosol-generating material is substantially free of plant material. In some embodiments, the aerosol-generating material is substantially free of tobacco.

[0062] The aerosol-generating material may include or be an "amorphous solid." An amorphous solid may be a "monolithic solid." In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that can retain a fluid, such as a liquid, within it. In some embodiments, the aerosol-generating material may comprise from about 50%, 60%, or 70% to about 90%, 95%, or 100% amorphous solid by weight.

[0063] The aerosol-generating material may comprise an aerosol-generating film. The aerosol-generating film may be a sheet, optionally shredded to form shredded sheets. The aerosol-generating sheet or shredded sheet may be substantially tobacco-free.

[0064] In this disclosure, a "non-combustion" aerosol delivery system refers to a system in which the constituent aerosol-generating materials of the aerosol delivery system (or its components) do not burn or combust to deliver at least one component to the user.

[0065] In some embodiments, the delivery system may be a non-combustion aerosol delivery system, for example, an electrically powered non-combustion aerosol delivery system.

[0066] In some embodiments, the non-combustion aerosol delivery system may be an electronic cigarette (also called a vaping device or electronic nicotine delivery system (END)), although it is not necessary for the aerosol-generating material to include nicotine.

[0067] In some embodiments, the non-combustion aerosol delivery system may be an aerosol-generating material heating system (also called a heated tobacco system), an example of which is a tobacco heating system.

[0068] In some embodiments, the non-combustion aerosol delivery system may be a hybrid system that generates an aerosol by heating one or more of a plurality of aerosol-generating materials. Each aerosol-generating material may be, for example, in solid, liquid, or gel form and may or may not contain nicotine. In some embodiments, the hybrid system may include a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material may include, for example, tobacco or a non-tobacco product.

[0069] Generally, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and a consumable item for use with the device.

[0070] In some embodiments, the present disclosure relates to consumables including aerosol-generating materials configured for use with non-combustion aerosol-delivery devices. These consumables may be referred to as "articles" throughout this disclosure.

[0071] In some embodiments, the non-combustion aerosol delivery system, e.g., the non-combustion aerosol delivery device, may include a power source and a controller. The power source may be, for example, an electrical power source or a heat-generating power source. In some embodiments, the heat-generating power source may include a carbon substrate that is energized to distribute power as heat to an aerosol-generating material or a heat transfer material in proximity to the heat-generating power source.

[0072] In some embodiments, the non-combustion aerosol delivery system may include an area for receiving a consumable, an aerosol generator, an aerosol-generation area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0073] In some embodiments, consumables for use with non-combustion aerosol-delivery devices may include an aerosol-generating material, an aerosol-generating material storage region, an aerosol-generating material transport component, an aerosol generator, an aerosol-generating region, a housing, a wrapper, a filter, a mouthpiece, and / or an aerosol modifier.

[0074] The aerosol delivery device can accept an article comprising an aerosol-generating material for heating. An "article" in this context is a component that, during use, contains the aerosol-generating material and is heated to volatilize the aerosol-generating material, and optionally other components as well. A user can insert the article comprising the aerosol-generating material into the aerosol delivery device, heat it to generate an aerosol, and then inhale the aerosol. The article can be, for example, of a predetermined or specific size to be placed within the heating chamber of the device.

[0075] 1 shows an aerosol delivery device 100 for generating an aerosol from an aerosol-generating material. Generally, device 100 heats a replaceable article 300 containing an aerosol-generating material to generate an aerosol or other inhalable medium that can be inhaled by a user. Article 300 and device 100 constitute an aerosol delivery system.

[0076] The device 100 comprises a main body 101. The main body 101 comprises a heating chamber for heating an aerosol-generating material. A housing 102 surrounds and houses the various components of the main body 101. One end of the main body 101 defines an opening 103 that communicates with the heating chamber. An article 300 is inserted at least partially into the heating chamber through the opening 103 and is heated by an aerosol generator 150 contained within the housing 102. In use, the article 300 is heated by one or more components of the aerosol generator 150.

[0077] The aerosol delivery device 100 defines a longitudinal axis X.

[0078] Device 100 includes an electrical component, such as a connector / port 160, to which a cable can be connected to charge device 100. For example, connector 160 may be a charging port, such as a USB charging port. In some implementations, connector 160 may also be used to transfer data between device 100 and other devices (e.g., computing devices).

[0079] The device 100 includes a power source 170, such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), alkaline batteries, etc. The battery is electrically connected to the aerosol generator 150 to power the aerosol generator 150 as needed under the control of a controller.

[0080] Device 100 includes an electronic module 112. Electronic module 112 may include, for example, a printed circuit board (PCB). The PCB may support at least one controller (such as a processor) and memory. The PCB may also include one or more electrical tracks for electrically connecting various electronic components of device 100. For example, battery terminals may be electrically connected to the PCB to distribute power throughout device 100.

[0081] The main body 101 defines the ends of the device 100. The end closest to the opening 103 may be referred to as the proximal end (or mouth end) 104 of the device 100, which is closest to the user's mouth in use. In use, the user inserts the article 300 into the opening 103, activates the aerosol generator 150 to begin heating the aerosol-generating material, and inhales the aerosol generated within the device, causing the aerosol to flow through the device 100 along a flow path toward the proximal end 104.

[0082] The other end of the device furthest from opening 103 may be referred to as distal end 106, and is the end farthest from a user's mouth in use. When a user inhales the aerosol generated by device 100, the aerosol flows toward proximal end 104. As used herein, the terms proximal and distal are described with reference to the relative positions of each component in the proximal-distal direction along the longitudinal axis of device 100.

[0083] As used herein, an "integral component" refers to a component that cannot be separated into two or more pieces after assembly of device 100. An "integral molded" refers to two or more features that are formed as an integral component during the manufacture of the component.

[0084] In one embodiment, the aerosol generator 150 includes an induction heating system that includes a magnetic field generator. The magnetic field generator includes an inductor coil assembly. The aerosol generator 150 includes a heating element, also called a susceptor.

[0085] The susceptor is a material that can be heated by a varying magnetic field (e.g., an AC magnetic field). The susceptor may be an electrically conductive material, and the varying magnetic field penetrates the susceptor to cause induction heating. The heating material may be a magnetic material, and the varying magnetic field penetrates the magnetic material to cause magnetic hysteresis heating. The susceptor may be both electrically conductive and magnetic, and can be heated by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

[0086] The aerosol generator 150 is an induction heating assembly that includes various components for heating the aerosol-generating material of the article 300 via an induction heating process. Induction heating is a process in which an electrically conductive object (such as a susceptor) is heated by electromagnetic induction. The induction heating assembly may include, for example, an induction element, such as one or more inductor coils, and a device for passing a varying current (e.g., AC current) through the induction element. The varying current in the induction element generates a varying magnetic field. The varying magnetic field penetrates a susceptor appropriately positioned relative to the induction element, generating eddy currents within the susceptor. The susceptor has an electrical resistance to the eddy currents, and this resistance causes the flow of eddy currents to heat the susceptor via Joule heating. If the susceptor includes a ferromagnetic material, such as iron, nickel, or cobalt, the susceptor may also be heated by magnetic hysteresis losses, as the orientation of magnetic dipoles within the susceptor changes with the varying magnetic field. Induction heating, compared to conduction heating, for example, allows for rapid heating because heat is generated inside the susceptor. Also, since no physical contact is required between the induction heater and the susceptor, there is a high degree of freedom in terms of structure and application.

[0087] The inductor coil assembly includes an inductor coil. In some embodiments, the number of inductor coils may vary. In some embodiments, more than one inductor coil may be used. The inductor coil assembly also includes a coil support. The coil support is tubular.

[0088] The heating element is part of a heating assembly. The heating element in this example is hollow and defines at least a portion of a receptacle in which the aerosol-generating material is contained. For example, the item 300 is inserted into the heating element. The heating element is tubular with a circular cross section. The heating element has a substantially constant diameter along its axial direction.

[0089] In embodiments, the heating assembly defines a receptacle, and the heating element extends within the receptacle. The heating element may include a pin or blade disposed to penetrate the consumable. In embodiments, the consumable includes the heating element, and the aerosol delivery device includes an inductor coil for inductively heating the heating element within the consumable.

[0090] The heating element is made of an electrically conductive material suitable for electromagnetic induction heating. The susceptor in this example is made of carbon steel. It will be appreciated that other suitable materials may also be used, such as ferromagnetic materials such as iron, nickel, cobalt, etc.

[0091] In other embodiments, the features acting as heating elements are not limited to induction heating. The features acting as heating elements may be heated by electrical resistance. Thus, the aerosol generator 150 may include electrical contacts for electrical connection with a device for electrically activating the heating element by passing a flow of electrical energy through the heating element.

[0092] The receptacle and article 300 are sized to accommodate the heating element. This helps ensure that heating is most efficient. In this example, article 300 comprises an aerosol-generating material. The aerosol-generating material is positioned within the receptacle. Article 300 may also comprise other components, such as a filter, wrapping material, cooling structure, etc.

[0093] 2 shows an exploded perspective view of a user interaction assembly 180 for an aerosol delivery device. The user interaction assembly 180 includes a cover mechanism 181 and a button assembly 200. The user interaction assembly 180 may be used with the aerosol delivery device 100 of FIG. 1 and will be described below with reference to that device. In embodiments, the user interaction assembly 180 may be used with other device configurations.

[0094] The body 202 is provided at one end of the device 100. The body 202 is a part of the body 101 of the device 100. The body 202 is a rigid member. In an embodiment, the body 202 may be integrally molded with other components of the device 100.

[0095] The body 202 defines an opening 103 of the device 100. The opening 103 is in communication with the heating chamber. The opening 103 is dimensioned to receive at least a portion of an article comprising an aerosol-generating material. The cover mechanism 181 includes a cover element 182 positioned to selectively cover the opening 103. The button assembly 200 includes an actuation member 212. The actuation member 212 is a generally annular member. The actuation member 212 is provided for selectively actuating the cover element 182. The cover element 182 pivots between open and closed positions to selectively block the opening 103. In embodiments, the cover member 182 may, for example, slide linearly between the open and closed positions.

[0096] The cam mechanism 183 is provided to drive the cover element 182 in response to action of the actuating member 212. The cam mechanism 183 acts as a drive mechanism. In embodiments, other mechanisms, such as a gear mechanism, may be provided to act as the drive mechanism.

[0097] The inner and outer cover elements 184, 185 extend over at least a portion of the body 202. The inner and outer cover elements 184, 185 at least partially define the opening 103. One or both of the inner and outer cover elements 184, 185 may be omitted.

[0098] The actuating member 212 is arranged to rotate on the body 202 to actuate the cover element 182. The actuating member 212 covers a portion of the body 202. A portion of the body 202 extends within the actuating member 212. The rotation axis of the actuating member 212 is parallel to the longitudinal axis of the heating chamber. The rotation axis of the actuating member 212 is spaced apart from the longitudinal axis of the heating chamber. The opening 103 is spaced apart from the actuating member 212. The opening 103 is spaced apart radially from the rotation axis of the actuating member 212. The opening 103 does not overlap with the actuating member 212 in a plane perpendicular to the rotation axis of the actuating member 212.

[0099] 2 and 3, an aerosol delivery device button assembly 200 is shown in an exploded view in Figure 2 and in cross section in Figure 3. The aerosol delivery device button assembly 200 is located at the proximal end 104 of the device 100.

[0100] The button assembly is configured to actuate in response to two different user interactions. The first interaction is a pressing interaction. The second interaction is a rotational interaction. The pressing interaction causes a pressing actuation of the button assembly 200, and the rotational interaction causes a rotational actuation of the button assembly 200. The pressing actuation is configured to cause an electrical state change of the device 100, e.g., sending a signal to a controller to change the operational state of the device (e.g., to initiate operation of the aerosol generator or change the operational mode, etc.). The rotational actuation is configured to cause a mechanical state change of the device 100, e.g., mechanical actuation of the cover mechanism 180.

[0101] An electrical switch 204 is provided on the body 202. The electrical switch 204 is provided to be actuated in response to user interaction with the button assembly 200. The electrical switch 204 is electrically connected to the electronic module 112. The electrical switch 204 is operable in response to the application of a biasing force.

[0102] The switch 204 may be a mechanical switch that operates in response to mechanical movement in the direction of the longitudinal axis. In an embodiment, the switch 204 may be a sensor. The switch 204 may be a pressure sensor that operates in response to the application of pressure.

[0103] The button assembly 200 includes a pressing member 206. The intermediate member 220 is provided between the pressing member 206 and the switch 204. The cover member 230 extends above the pressing member 206.

[0104] The push member 206 forms part of an actuation member 212. The actuation member 212 includes an actuation ring 214. The actuation ring 214 includes an inner actuation component 216 and an outer actuation component 218.

[0105] The outer actuating component 218 is rotatably fixed to the inner actuating component 216. The outer actuating component 218 surrounds the inner actuating component 216. The outer actuating component 218 partially defines a portion of the exterior surface of the aerosol delivery device 100. The outer actuating component 218 is a tubular body. The outer actuating component 218 forms a peripheral wall around the inner actuating component 216. In embodiments, the outer and inner actuating components 218, 216 may be combined as an integral component.

[0106] The inner and outer actuating components 216, 218 are formed from different materials, with the inner actuating component 216 being formed from a relatively low friction material, which has the advantage of reducing wear.

[0107] Body 202 includes an actuation member mount 203. An inner actuation component 216 is rotatably engaged with actuation member mount 203. Actuation member mount 203 limits the linear movement of actuation member 212 relative to the body. Inner actuation component 216 includes a shoulder 217 that acts as a locating feature that engages with actuation member mount 203. Shoulder 217 extends around the inner surface of actuation member 420.

[0108] The actuation member mount 203 includes a mount arrangement 219. The mount arrangement 219 is resilient. In this embodiment, the actuation member mount 203 includes four clips. As the actuation member 212 rotates on the body 402, the clips slide along shoulders 217. Engagement of the clips with the shoulders 217 prevents axial, i.e., translational, movement of the actuation ring 214.

[0109] The actuation ring 214 defines a central recess 225. The actuation member mount 203 extends into the central recess 225. The push member extends into the central recess 225. The push button extends into the actuation member mount 203 on the body.

[0110] The pressing member 206 is a rigid member. The pressing member 206 is formed as a linearly actuating member with a disk portion (acting as a proximal portion 210) and a post portion (acting as a distal protruding portion 208). The disk portion 210 is the pressing portion that receives a biasing force during use. The post portion 208 is a leg that extends perpendicularly from the top surface 210 along the axis X of the button assembly 200.

[0111] The disk portion 210 of the push member 206 is generally circular. An actuation ring 214 surrounds the push member 206. An outer actuation component 218 surrounds the disk portion 210 of the push member 206. In embodiments, some or all of the actuation ring 214 may surround some or all of the push member 206 to form the actuation member 212.

[0112] The actuation ring 214 is configured to rotate relative to the stationary body 202 about a rotation axis X. The pressing member 206 is configured to rotate relative to the body 202.

[0113] The peripheral member 240 extends around the pressing member 206. The peripheral member 240 extends from the disk portion 210. The peripheral member 240 is disposed on the periphery of the top surface 210 of the pressing member 206. The peripheral member 240 is an elastically deformable member. The peripheral member 240 is fixedly attached to the pressing member 206. In some embodiments, the peripheral member 240 may be integrally molded with the pressing member 206. The peripheral member may form a fluid seal with the pressing member 206. An inner side 241 of the peripheral member 240 is attached to an edge of the pressing member 206. The peripheral member 240 is fixedly attached to the periphery with the actuation ring 214. The peripheral member 240 may form a fluid seal with the actuation ring 214. An outer peripheral side 242 of the peripheral member 240 rests on the inner actuation component 216. The proximal side of the inner actuation component 216 forms a surround seat 241. The push member 206 is configured to rotate with the actuation ring about the axis of rotation X. The surround 240 is configured to rotate with the actuation ring about the axis of rotation X. The surround 240 forms a seal between the push member 206 and the actuation ring 214. The surround 240 helps limit the ingress of foreign matter into the device.

[0114] The surround 240 includes an angled portion between its attachment to the push member 206 and the actuation ring 214. The angled portion of the surround 240 is deformable to facilitate relative movement between the push member 206 and the actuation ring 214 along the longitudinal axis X. The surround 240 is made from a resiliently deformable material such that the relative movement is biased toward its original, unactuated position.

[0115] In embodiments, the surround 240 may extend around only a portion of the top surface 210 of the push member 206. In embodiments, the surround may extend around the entire top surface 210 of the push member 206. In embodiments, the surround may be attached to the outer actuation component 218 of the actuation ring 214.

[0116] The actuation ring 214 is carried by the body 202. In an embodiment, the actuation ring 214 is translationally fixed relative to the body 202. Thus, the actuation ring 214 is rotatable relative to the body 202 and is prevented from significant axial movement relative to the body.

[0117] The pressing member 206 extends into the intermediate member 220. The post portion 208 of the pressing member 206 extends into the intermediate member 220, with the distal free end of the post portion 208 received within the intermediate member 220.

[0118] The intermediate member 220 is shaped as a cup. In embodiments, the intermediate member may have other configurations. The protruding member 208 extends into a cavity defined by the cup. The cup includes a base 222. The base 222 has an inner surface that contacts the free end of the post portion 208 of the pressing member 206. The base 222 has an outer surface that is configured to abut or bias against the switch 204. The base 222 acts on the switch.

[0119] The intermediate member 220 includes a peripheral wall 224 that extends generally perpendicular to the base 222. The peripheral wall surrounds the free end of the protruding portion 208 distal from the top surface 210 of the pressing member 206. The free end of the peripheral wall 224 is fixedly attached to the body 202.

[0120] The intermediate member 220 is rotatably fixed to the main body 202. The intermediate member 220 is fixedly attached to the main body. The intermediate member is elastically deformable relative to the main body.

[0121] The fixed body 202 includes an opening 205. The intermediate member 220 seals the opening 205. The intermediate member 220 is formed from a deformable material. The intermediate member is formed from a flexible or elastic material. Thus, the intermediate member 220 is deformable to act on the switch 204 and activate the switch 204.

[0122] The intermediate member forms a fluid seal with the body 202 to close the opening 205. This is advantageous, for example, to prevent condensation or foreign matter from passing through the opening 205. A bore in the body 202 defines the opening 205. The intermediate member 220 is at least partially received within the bore. The bore contacts the body around the switch 204 to provide the seal.

[0123] The protruding portion 208 of the pressing member 206 protrudes through the opening 205 in the body 202 .

[0124] A cover member 230 is provided on the pressing member 206. The cover member 230 defines a user-engaging pressing surface. The cover member 230 is provided over the inner proximal extent of the actuation ring 214. The cover member is received within the actuation ring 214. The cover member 230 extends above the pressing member 206. The cover member 230 covers the pressing member 206. The cover member covers the peripheral member. The cover member 230 may be integrally formed with the pressing member 206 or may be omitted.

[0125] The cover member 230 is a rigid member. The cover member is movable together with the pressing member 206. The cover member 230 is movable in the axial direction. The pressing member 206 is biased by engagement with the pressing member. The cover member 230 is rotatably fixed to the pressing member 206 and rotates together with the pressing member 206.

[0126] In use, a user engages the user-engaged pressing surface of cover member 230. This may be referred to as a first user action. Pressing member 206 is pressed and moves along axis X. When pressed axially, pressing member 206 moves toward switch 204.

[0127] The intermediate member 220 is configured to act between the pressing member 206 and the switch 204. When the pressing member 206 moves towards the switch 204, the intermediate member 220 deforms and activates the switch 204.

[0128] A user can also engage button assembly 200 through a rotational interaction, which may be referred to as a second user action. The rotational actuation is configured to cause a change in the mechanical state of device 100. Pressing member 206 is configured to rotate relative to intermediate member 220 about rotation axis X. Pressing member 206 forms a bearing surface with intermediate member 220. Resistance at the bearing surface between the pressing member and intermediate member 220 is reduced, causing the pressing member to rotate relative to the intermediate member.

[0129] Rotation of the pressing member 206 rotates the actuating member 212. The actuating member rotates on the body 202 to actuate the cover mechanism 180. The cover mechanism 180 is rotatably operable. The cover element 182 is rotated by the cover mechanism 180 between a relatively open position and a relatively closed position to block the opening 103. The pressing member 206 is movable between an actuated position and an inactuated position. Linear actuation of the actuating member 212 from the actuated position and the inactuated position activates the switch 204.

[0130] When the pressing member 206 moves to the actuated position, the pressing member 206 deforms the intermediate member 220. The distal end of the protruding portion 208 of the pressing member 206 contacts the intermediate member 220. The protruding portion 208 of the pressing member 206 forms a bearing surface together with the intermediate member 220. The intermediate member 220 acts on the switch 204 to activate the switch 204.

[0131] In the inactivated position, the pressing member 206 is in contact with the intermediate member 220. The protruding portion 208 of the pressing member 206 forms a bearing surface with the intermediate member 220 to facilitate relative rotation. In an embodiment, the base 222 of the intermediate member 220 is not in contact with the distal end of the protruding portion 208 in the inactivated position. In an embodiment, the intermediate member 220 is not in contact with the pressing member 206 at all in the inactivated position.

[0132] In an embodiment, the intermediate member 220 is configured to bias the push member 206 toward the inactivated position. The intermediate member 220 is made of a resilient material to provide resistance to actuation of the switch 204.

[0133] In an embodiment, the peripheral member 240 is configured to bias the pressing member 206 toward the inactivated position. The angled portion of the peripheral member 240 spaces the distal end of the protruding portion 208 away from the base 222 of the intermediate member 220. When the pressing member 206 is pressed, the biasing force is overcome and the peripheral member 240 deforms.

[0134] Electrical switch 204 is configured to implement the operation of the aerosol delivery device. In embodiments, activation of switch 204 turns on device 100, e.g., initiates a predetermined use session of the aerosol delivery device. In embodiments, activation of switch 204 causes aerosol delivery device 100 to operate in a first standard or basic operating mode. In embodiments, reactivation of switch 204 by user action within a predetermined period of time changes the use mode of the device. In embodiments, reactivation of switch 204 by user action may turn the device off. In embodiments, switch 204 may require continuous activation by user action during a use session.
