[0036] As used herein, the term "aerosol-forming material" refers to a material that can generate an aerosol when heated, irradiated, or energized in any other manner, for example. Aerosol-forming materials can be, for example, in the form of a solid, liquid, or gel, which may or may not contain active substances and / or flavorings. Aerosol-forming materials may include any plant-based material, such as tobacco-containing materials, including one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Aerosol-forming materials may also include other non-tobacco products, which may or may not contain nicotine, depending on the product. Aerosol-forming materials may be, for example, in the form of a solid, liquid, gel, or wax. Aerosol-forming materials may also be, for example, a combination or blend of materials. Aerosol-forming materials may also be known as "smokable materials."

[0037] The aerosol-generating material may include a binder and an aerosol-forming agent. Optionally, an active agent and / or a filler may also be present. Optionally, a solvent, such as water, may also be present, and one or more other components of the aerosol-generating material may or may not be soluble in the solvent. 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.

[0038] 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 some fluid, such as a liquid, within the amorphous solid. In some embodiments, the aerosol-generating material may contain, for example, from about 50%, 60%, or 70% amorphous solid by weight, up to about 90%, 95%, or 100% amorphous solid by weight.

[0039] The aerosol-generating material may include an aerosol-generating film. The aerosol-generating film may include or be a sheet that may optionally be shredded to form a shredded sheet. The aerosol-generating sheet or shredded sheet may be substantially free of tobacco.

[0040] According to the present disclosure, a "non-combustion" aerosol delivery system is one in which the constituent aerosol-forming materials (or components of the constituent aerosol-forming materials) of the aerosol delivery system are not combusted or burned to facilitate delivery of at least one substance to a user.

[0041] In some embodiments, the delivery system is a non-combustion aerosol delivery system, such as a powered non-combustion aerosol delivery system.

[0042] In some embodiments, the non-combustion aerosol delivery system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine in the aerosol-generating material is not a requirement.

[0043] In some embodiments, the non-combustion aerosol delivery system is an aerosol-generating material heating system, also known as a non-combustion heating system. One example of such a system is a tobacco heating system.

[0044] In some embodiments, the non-combustion aerosol delivery system is a hybrid system that generates an aerosol using a combination of aerosol-generating materials, where one or more aerosol-generating materials can be heated. Each of the aerosol-generating materials can be, for example, in solid, liquid, or gel form and can contain nicotine or not. In some embodiments, the hybrid system includes a liquid or gel aerosol-generating material and a solid aerosol-generating material. The solid aerosol-generating material can include, for example, tobacco or a non-tobacco product.

[0045] Typically, a non-combustion aerosol delivery system may include a non-combustion aerosol delivery device and a consumable item for use with the non-combustion aerosol delivery device.

[0046] In some embodiments, the present disclosure relates to consumables, sometimes referred to as articles throughout this disclosure, that comprise aerosol-generating materials and are configured for use with non-combustion aerosol delivery devices.

[0047] In some embodiments, a non-combustion aerosol delivery system, such as a non-combustion aerosol delivery device of a non-combustion aerosol delivery system, can include a power source and a controller. The power source can be, for example, an electrical power source or a heat-generating power source. In some embodiments, the heat-generating power source includes a carbon substrate that can be energized to deliver power in the form of heat to an aerosol-generating material or a heat-transfer material proximate the heat-generating power source.

[0048] In some embodiments, the non-combustion aerosol delivery system may include an area for receiving a consumable, an aerosol generator, an aerosol-generating area, a housing, a mouthpiece, a filter, and / or an aerosol modifier.

[0049] In some embodiments, consumables for use with non-combustion aerosol delivery devices may include aerosol-generating materials, aerosol-generating material storage areas, aerosol-generating material transfer components, aerosol generators, aerosol-generating areas, housings, packaging, filters, mouthpieces, and / or aerosol modifiers.

[0050] The aerosol-generating device can accept an article containing an aerosol-generating material for heating. An "article" in this context is a component that includes or contains the aerosol-generating material when used, and optionally other components when used, that is heated to volatilize the aerosol-generating material. A user may insert the article into the aerosol-generating device before the article is heated to generate an aerosol, and the user then inhales the aerosol. The article may be of a predetermined or specific size, for example, configured to be placed in a heating chamber of the device sized to accept the article.

[0051] 1 shows an aerosol delivery device 100 for generating an aerosol from an aerosol-generating material. Generally, device 100 can be used to heat a replaceable article 300 containing an aerosol-generating material to generate an aerosol or other inhalable medium that is inhaled by a user of device 100. Article 300 and device 100 together form an aerosol delivery system 10.

[0052] The device 100 comprises a body 101. The body 101 comprises a chamber 105 (see FIG. 2). A housing 102 surrounds and houses the various components of the body 101. One end of the body 101 is formed with an opening 103 that communicates with the chamber 105. The article 300 may be inserted at least partially into the chamber 105 through the opening 103 for heating by the aerosol generator 150 (see FIG. 2). During use, the article 300 may be heated by one or more components of the aerosol generator 150.

[0053] Device 100 also includes a button assembly 200 that, when pressed, operates device 100. For example, a user may turn on device 100 by manipulating button assembly 200. Button assembly 200 may be assembled as part of other assemblies of aerosol delivery device 100.

[0054] The aerosol generator 150 defines a longitudinal axis X.

[0055] 2 shows a schematic cross-sectional view of device 100. Device 100 includes an electrical component, such as a connector / port 160, that can accept a cable for charging device 100. For example, connector 160 may be a charging port, such as a USB charging port. In some examples, connector 160 may additionally or alternatively be used to transfer data between device 100 and another device, such as a computing device.

[0056] Device 100 includes a power source 170, e.g., a battery, such as a rechargeable or non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (e.g., lithium-ion batteries), nickel batteries (e.g., nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to aerosol generator 150 to provide power to heat the aerosol-generating material as needed under the control of a controller.

[0057] Device 100 includes an electronics module 112. Electronics 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 together. For example, battery terminals may be electrically connected to the PCB so that power can be distributed throughout device 100.

[0058] Body 101 defines the ends of device 100. The end of device 100 closest to opening 103 may be known as the proximal end (or mouth end) 104 of device 100, as it is closest to a user's mouth during use. During use, a user inserts article 300 into opening 103, activates aerosol generator 150 to begin heating the aerosol-generating material, and inhales the aerosol generated within device 100. This causes the aerosol to flow through device 100 along a flow path toward the proximal end of device 100.

[0059] The other end of the device furthest from opening 103 may be known as the distal end 106 of device 100, as it is the end furthest from a user's mouth during use. When a user inhales the aerosol generated within device 100, the aerosol flows in a direction toward the proximal end of device 100. The terms proximal and distal as applied to features of device 100 are described by reference to the relative orientation of such features with respect to one another in the proximal-distal direction along the longitudinal axis.

[0060] As used herein, the term integral component refers to a component of device 100 that cannot be separated into two or more components after assembly of device 100. Integrally formed refers to two or more features that are formed into a unitary component during the manufacturing stage of the component.

[0061] Air flow passage 180 extends through body 101. Air flow passage 180 extends to air inlet 190. Other air flow arrangements are envisioned. For example, air flow may be provided between a receptacle defining chamber 105 and item 300.

[0062] The aerosol generator 150 includes a heater 152. In one example, the aerosol generator 150 includes an induction heating system including a magnetic field generator. The magnetic field generator includes an inductor coil assembly. The aerosol generator 150 includes a heating element, also known as a susceptor.

[0063] The susceptor is a material that can be heated by penetration by a varying magnetic field, such as an alternating magnetic field. The susceptor may be a conductive material, such that penetration by the varying magnetic field causes induction heating of the heating material. The heating material may be a magnetic material, such that penetration by the varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both conductive and magnetic, such that the susceptor is heatable by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

[0064] 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 of heating a conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may include an induction element, such as one or more inductor coils, and a device for passing a variable current, such as an alternating current, through the induction element. The variable 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 therefore, the flow of eddy currents against this resistance causes the susceptor to heat by Joule heating. If the susceptor includes a ferromagnetic material such as iron, nickel, or cobalt, heat can also be generated by magnetic hysteresis losses within the susceptor, i.e., by the change in orientation of magnetic dipoles within the magnetic material as a result of alignment with the varying magnetic field. Induction heating generates heat inside the susceptor, allowing for faster heating compared to, for example, conduction heating, and does not require any physical contact between the induction heater and the susceptor, allowing for greater flexibility in design and application.

[0065] The inductor coil assembly includes an inductor coil. In embodiments, the number of inductor coils varies. In embodiments, two or more inductor coils are used. The inductor coil assembly also includes a coil support. The coil support is tubular.

[0066] The heating element is part of heater 152. The heating element in this example is hollow, thus defining at least a portion of a receptacle within which the aerosol-generating material is received. For example, item 300 can be inserted into the heating element. The heating element is tubular with a circular cross-section. The heating element has a substantially constant diameter along the axial length of the heating element.

[0067] In embodiments, the heating assembly defines a receptacle, and the heating element is upstanding within the receptacle. The heating element may comprise a pin or blade positioned to penetrate the consumable. In embodiments, the consumable comprises a heating element, and the aerosol delivery device comprises an inductor coil configured to inductively heat the heating element within the consumable.

[0068] The heating element is formed from an electrically conductive material suitable for heating by electromagnetic induction. The susceptor in this example is formed from carbon steel. It will be appreciated that other suitable materials may be used, for example, ferromagnetic materials such as iron, nickel, or cobalt.

[0069] In other embodiments, the features functioning as heating elements may not be limited to being inductively heated. Thus, the features functioning as heating elements may be heatable by electrical resistance. Thus, the aerosol generator 150 may include electrical contacts for electrically connecting with a device for electrically activating the heating element by passing a flow of electrical energy through the heating element.

[0070] The receptacle and article 300 are sized so that the article 300 can be received by the heating element. This helps ensure that heating is most efficient. In this example, the article 300 includes an aerosol-generating material. The aerosol-generating material is disposed within the receptacle. The article 300 may also include other components, such as a filter, packaging material, and / or a cooling structure.

[0071] An air flow path 180 extends from the receptacle. The air flow path 180 is at the distal end. The air flow path 180 protrudes from the heating element. The air flow path 180 extending from the heating element is defined by a flow path member 182. The heating element 220 and the flow path member 182 form part of an air flow path arrangement 181.

[0072] The flow path member 182 extends between the heating element and the opening 190. The flow path member 182 is tubular. The flow path member 182 defines a bore. The flow path member extends axially along the length of the flow path member.

[0073] 3 shows an exploded perspective view of a cover assembly 400 for an aerosol delivery device. Cover assembly 400 may be used with aerosol delivery device 100 of FIGS. 1 and 2 and will be described with reference to aerosol delivery device 100. In embodiments, cover assembly 400 is used with other device components. Cover assembly 400 includes a cover mechanism 401.

[0074] The cover assembly 400 includes a body 402. The body 402 is a portion of the body 101 of the aerosol delivery device 100. The body 402 is a rigid member. The body 402 defines a portion of the housing 102. A seal 405 is provided between the body 402 and other components of the housing 102 of the aerosol delivery device 100. The seal 405 extends around the entire periphery of the body 402. In other embodiments, the body 402 may be integrally formed with other components of the housing 102. The body 402 defines the proximal end of the device 100.

[0075] Body 402 defines opening 103 of aerosol delivery device 100. Opening 404 communicates with chamber 105. Opening 404 is dimensioned to receive at least a portion of an article containing aerosol-generating material, such as article 300.

[0076] The body 402 has an outer portion 407. The outer portion 407 of the body 402 includes a recess 407a. An opening 408 is defined in the recess 407a.

[0077] The cover mechanism 401 of the cover assembly 400 includes a cover member 410 arranged to selectively cover the opening 404. An actuation member 420 is provided for selectively actuating the cover member 410. The cover member 410 is in slidable contact with the main body 402. The cover member 410 is generally planar. The cover member 410 includes a blade portion 412 arranged to cover the opening. The cover member 410 includes a first arm portion 414. The first arm portion 414 extends from the blade portion 412. The cover member 410 includes a second arm portion 415. The second arm portion 415 extends from the blade portion 412. A recess 416 is defined between the first arm portion 414 and the second arm portion 415.

[0078] The cover member 410 includes a lower pivot pin 411 that functions as a pivot member. The lower pivot pin 411 extends from the first arm portion 414. The lower pivot pin 411 is spaced apart from the blade portion 412. The cover member 410 includes an upper pivot pin 413 that functions as a pivot member. One of the upper pivot pin 413 and the lower pivot pin 411 may be omitted. The upper pivot pin extends from the first arm portion 414. The upper pivot pin 413 is spaced apart from the blade portion 412. The upper pivot pin 413 extends from the opposite side of the first arm portion 414 to the lower pivot pin 411. The upper pivot pin 413 and the lower pivot pin 411 are coaxial. The upper pivot pin 413 and the lower pivot pin 411 extend in the longitudinal axial direction.

[0079] The cover member 410 is a unitary component. The cover member 410 is integrally formed. In other embodiments, the cover member 410 may be a composite component formed of multiple parts. For example, the upper pivot pin 413 and the lower pivot pin 411 may be a single pin that passes through the first arm portion 414.

[0080] The cover mechanism 401 includes a cam mechanism 419 configured to drive the cover member 410 in response to movement of the actuating member 420. The cam mechanism 419 functions as a drive mechanism. The cam mechanism 419 includes a cam element 418 and a corresponding cam slot 434.

[0081] The cover member 410 includes a cam element 418. The cam element 418 includes a protrusion. The cam element 418 includes a pin. In embodiments, the cam element 418 includes any suitable formation for forming part of a cam mechanism. The cam element 418 is disposed on the second arm portion 415. The cam element 418 stands upright from the cover member 410. The cam element 418 extends in the longitudinal axial direction.

[0082] The cover member 410 is received in a recess 407a in the body 402. The recess 407a allows the cover member 410 to be spatially efficiently accommodated by the body 402 and prevents the evacuation of debris from the chamber 105.

[0083] The body 402 includes an upper body member 409. The upper body member 409 defines an opening 409a. The upper body member 409 includes an annular member 448 that surrounds the opening 409a. In embodiments, the annular member 448 may be omitted. The upper body member 409 is attached to the lower body member of the body 402 such that the opening 409a is aligned with the opening 404. The upper body member 409 includes an opening 417 for receiving the upper pivot pin 413 of the cover member 410.

[0084] The upper pivot pin 413 is received in an opening 417 in the upper body member 409. The lower pivot pin 411 is received in an opening 408 in the body 402. The cover member 410 is pivotally held between the upper body member 409 and the lower body member 402. This provides a robust cover assembly because the cover member 410 can be securely held between two fixed components. The cover member can pivot about an axis defined by the upper pivot pin 413 and the lower pivot pin 411.

[0085] The cover mechanism 400 includes an actuating member 420. The actuating member 420 is a generally annular member. The actuating member is rotatably mounted.

[0086] The actuation member 420 defines an opening 422. The opening 422 is disposed in the center of the actuation member 420. The opening may be omitted.

[0087] The actuating member 420 is positioned to rotate on the body 402 to actuate the cover member 410. The actuating member 420 covers a portion of the body 402; that is, a portion of the body 402 extends within the actuating member 420. The rotational axis of the actuating member 420 is parallel to the longitudinal axis of the chamber 105. In an embodiment, the rotational axis is transverse or vertical. The rotational axis of the actuating member 420 is spaced from the longitudinal axis of the chamber 105 in a direction perpendicular to the longitudinal axis of the chamber 105. The opening 103 is spaced from the actuating member 420. The opening 103 is spaced from the actuating member 420 in a radial direction relative to the rotational axis of the actuating member 420. The opening 103 does not overlap with the actuating member 420 in a plane perpendicular to the rotational axis of the actuating member 420.

[0088] The above configuration helps provide a more compact configuration of the cover assembly 400 relative to a configuration in which the rotational axis of the actuating member 420 is aligned with the longitudinal axis of the chamber 105 or the opening 103 overlaps or is disposed below the cover member 410. The actuating member 420 may accommodate other components of the cover assembly 400 without obstructing the opening 103, allowing those components to be disposed within the plane of the actuating member 420. This may reduce the size of the cover assembly 400 in the axial direction of the aerosol delivery device 100. For example, as described below, at least one of the retention mechanism 450 and the user interface arrangement 470 may be disposed within the actuating member 420.

[0089] Aerosol delivery device 100 includes a user interface configuration 470. User interface configuration 470 is on actuation member 420. Actuation member 420 defines an opening 422. User interface configuration 470 is disposed in opening 422 of actuation member 420. In an embodiment, user interface configuration 470 extends above opening 422 of actuation member 420. In an embodiment, electrical connections of user interface configuration 470 extend through opening 422 to body 101 of aerosol delivery device 100. User interface configuration 470 may include at least one of a button, a touch screen, a display, and an indicator light, such as an LED. User interface configuration 470 may provide at least one of an indication of an operational state of device 100 and control of an operational state of device 400.

[0090] The user interface configuration 470 includes a protective plate 472. The protective plate 472 may be omitted. The actuating member 420 includes an outer actuating component 424 and an inner actuating component 426. The outer actuating component 424 is rotatably fixed to the inner actuating component 426. The outer actuating component 424 surrounds the inner actuating component 426. The outer actuating component 424 partially defines the outer surface of the aerosol delivery device 100. The outer actuating component 424 is a cylindrical body. The outer actuating component 424 forms a circumferential wall 425 around the inner actuating component 426. In an embodiment, the outer actuating component 424 and the inner actuating component 426 are an integral component.

[0091] The outer actuation component 424 includes a notch 446. The notch 446 is in the peripheral wall 425. The notch 446 receives the cover member 410.

[0092] The actuating member 420 defines an elongated cam surface 433. The elongated cam surface 433 is arcuate. The elongated cam surface 433 is defined by a cam slot 434. The cam slot 434 is formed by the inner actuating component 426. The cam slot 434 is a blind slot. That is, the cam slot 434 is closed at each end. The closed ends, in embodiments, function as travel limiters. The cam slot 434 defines a partial helical path about the rotational axis of the actuating member 420. That is, the cam slot 434 extends partially radially away from the rotational axis of the actuating member 420. The cam element 418 of the cover member 410 is received in the cam slot 434. The cam element 418 and the cam slot 434 together define a cam mechanism 419.

[0093] The inner and outer actuating components 424, 426 are formed of different materials. The inner actuating component 426 is formed of a relatively wear-resistant material. The inner actuating component 426 is formed of a relatively low-friction material. The inner actuating component 426 is resilient. Advantageously, this arrangement minimizes wear on the inner actuating component and reduces friction on the cover mechanism 401, while allowing freedom to select the material of the outer actuating component 426 to have properties suitable for the exterior surface of the aerosol delivery device 100.

[0094] The body 402 includes an actuating member mount 442. The inner component member 42 is rotatably engaged with the actuating member mount 442. The actuating member mount 442 substantially limits the movement of the actuating member 420 relative to the body to rotational movement. The actuating member 420 includes a locating feature (not shown) that engages with the actuating member mount 442. The locating feature is a ridge or other suitable feature that extends circumferentially around the inner surface of the actuating member 420. The actuating member mount 442 is spaced from an opening 408 in the body 402 that receives the lower pivot pin 411. The actuating member 420 is radially spaced from the opening 408 when attached to the actuating member mount 442. In this regard, the radial direction is relative to the axis of rotation of the actuating member 420. Thus, the cover member 410 pivots about a point external to the actuating member 420.

[0095] The actuation member mount 442 includes clips 443 that function as retention structures. The clips 443 are resilient. In this embodiment, the actuation member mount 442 includes four clips 443. The body 402 includes a recess 444 behind the clips. In this embodiment, the body 402 includes a recess 444 behind each clip. The recesses 444 provide clearance to accommodate radial inward deflection of the clips, allowing for a more compact arrangement.

[0096] The cover member 410 is partially disposed between the body 402 and the actuating member 420. The cover member 410 is in sliding contact with the body 402. The cover member 410 is in sliding contact with the actuating member 420. Such a configuration helps to limit the ingress of debris.

[0097] Figure 4 shows the cover mechanism 401 in its closed position, Figure 5 shows the cover mechanism 401 in its second open position, Figure 6 shows the cover mechanism 401 in its first open position, and Figure 7 shows the cover mechanism 401 in its closed position. In the first and second open positions of the cover mechanism 401, the cover member 410 is in a relatively open position. In the closed position of the cover mechanism 401, the cover member 410 is in a relatively closed position.

[0098] The cam slot 434 includes a first portion 434a and a second portion 434b. The first portion 434a defines a first range of movement of the actuating member 420. The second portion 434b defines a second range of movement of the actuating member 420. The first portion 434a defines a partial spiral about the axis of rotation of the cover member 410. That is, the first portion 434a follows a curved path about the axis of rotation of the cover member 410, with the radius of the path increasing along the extent of the path. The first portion 434a defines less than a full rotation of the spiral, such as a quarter turn.

[0099] The second portion 434b defines a partial circle centered about the axis of rotation of the cover member 410. That is, the second portion 434b follows a curved path centered about the axis of rotation of the cover member 410, with the radius of the path being constant along the extent of the path. The first portion 434a and the second portion 434b of the cam slot 434 are continuous. The second portion 434a is joined to the second portion 434b at the end of the second portion 434b closest to the axis of rotation of the cover member 410. Thus, the cam slot 434 defines a path relative to the axis of rotation of the actuating member 420 that is initially constant and then has an increasing radius.

[0100] Thus, the actuating member 420 is movable through a first range of movement in which the cover member 410 moves between a relatively open position of the cover member 410 and a closed position of the cover member 410, and a second range of movement in which the position of the cover member 410 does not change.

[0101] Rotation of the actuating member 420 relative to the body 402 through a first range of motion pivots the cover member 410 between a relatively open position and a relatively closed position. The cover mechanism 401 is configured to be selectively operated between a relatively open position and a relatively closed position. Such positions are relative to one another. In the relatively open position, at least a portion of the article 300 can pass through the opening 404. In the relatively closed position, at least a portion of the article 300 is prevented from passing through the opening 404. Rotating the actuating member 420 clockwise moves the cover member 410 toward the relatively closed position. Rotating the actuating member 420 counterclockwise moves the cover member 410 toward the relatively open position. In other embodiments, these directions may be reversed.

[0102] The term "relatively open position" refers to any position in which at least a portion of the article 300 can pass through the opening, i.e., it is understood to include a fully open position and an intermediate position that leaves sufficient space for a portion of the article 300 to be inserted. The term "relatively closed position" refers to any position in which a portion of the article 300 is prevented from passing through the opening 404, i.e., it is understood to include a fully closed position and an intermediate position in which there is not enough space for the article 300 to pass through the opening. In this embodiment, rotation of the actuating member 420 relative to the body 402 translates the cover member 410 to or from a fully closed position. The term "fully closed position" refers to the cover member 410 completely closing the opening 404. The terms "open" and "closed" as applied to features of the cover mechanism 300 are described relative to one another herein.

[0103] In the relatively open position, a portion of the cover member 410 is received in a notch 446 in the actuating member 420. The first arm portion 414 of the cover member 410 spaces the blade portion 412 of the cover member 410 from the pivot axis of the cover member 410. The second arm portion 415 of the cover member 410 spaces the blade portion 412 of the cover member 410 from the cam mechanism. This allows a small movement of the actuating member 420 to move the blade portion 412 through a range of movement large enough to fully traverse the opening 404.

[0104] The cover member 410 is positioned to pivot relative to the body 402. The cover member 410 is positioned to pivot in a direction perpendicular to the axis of rotation of the actuating member 420. The axis of rotation of the actuating member 420 is parallel to the longitudinal axis of the chamber 105. The axis of rotation of the actuating member 420 is offset from the longitudinal axis of the chamber 105. When the actuating member 420 is rotated by a user, the arcuate cam surface acts on the cam element 418, moving the cover member 410. As the cam element 418 advances within the cam slot 434, the cam element 418 is driven either farther or closer to the axis of rotation of the actuating member 420, depending on the direction of rotation of the actuating member 420. As the cover member 410 moves, the upper pivot pin 413 and the lower pivot pin 411 rotate within the opening 417 in the upper body member 409 and the opening 408 in the body 402, respectively.

[0105] In the relatively closed position, the peripheral wall 425 of the actuating member 420 is received in the recess 416 of the cover member 410, thereby minimizing the size of the notch 446 in the actuating member 420. Thus, the cover assembly 400 may be positioned such that the notch 446 is not exposed to the exterior of the aerosol delivery device 100 in either the fully open or fully closed position, reducing the likelihood of debris entering the cover mechanism 401 through the notch 446, which could cause clogging or increased wear.

[0106] Aerosol delivery device 100 is selectively operable in a first mode, a second mode, and a third mode. In an embodiment, aerosol delivery device 100 is operable in only the first mode and the second mode, or in at least four modes. In one embodiment, in the first mode, aerosol delivery device 100 is configured to operate heater 152 according to a first heating profile. In the second mode, aerosol delivery device 100 is configured to operate heater 152 according to a second heating profile. The second heating profile is different from the first heating profile. The peak temperature of the second heating profile is higher than the peak temperature of the first heating profile. The peak heating rate of the second heating profile is higher than the peak heating rate of the first heating profile. Thus, the second mode may be described as a boost mode. For example, the second mode may be configured to generate a higher utilization rate of smokable material. In an embodiment, these may be reversed. In an embodiment, heater 152 may be inoperable in the first mode. For example, the first mode may be a standby mode.

[0107] Movement of the actuating member 420 relative to the body 402 through the second range of movement selectively changes the aerosol delivery device 100 between the first mode and the second mode. Thus, the device 100 supports switching from the first mode to the second mode and from the second mode to the first mode depending on the direction of rotation of the actuating member 420. During movement of the actuating member 420 relative to the body 402 through the second range of movement, the cover member 410 remains stationary relative to the body 402.

[0108] The cover assembly 400 includes a switch 480. The switch 480 includes a sensor for detecting the position of at least a portion of the cover mechanism 401. The switch 480 is operable to operate the aerosol delivery device 100 in a first mode or a second mode in response to detecting the position of the cover mechanism 401. The switch 480 includes a Hall sensor 482 and a magnet 484. In an embodiment, the switch 480 includes different sensor configurations, such as one or more of an optical sensor, a potentiometer, and a mechanical switch. The Hall sensor 482 is fixed to a stationary portion of the cover mechanism 401. The magnet 484 is fixed to a moving portion of the cover mechanism 401. In this example, the Hall sensor 482 is fixed to the body 402, and the magnet 484 is fixed to the actuating member 420. In an embodiment, the magnet 484 is fixed to the cover member 410.

[0109] The Hall sensor 482 and the magnet 484 are positioned such that when the cover mechanism 401 is in the first open position, the magnet 484 is relatively far from the Hall sensor 482, and when the cover mechanism 400 is in the second open position, the magnet 484 is relatively close to the Hall sensor 482. In an embodiment, this may be reversed. In an embodiment, the magnet 484 may be adjacent to the Hall sensor 482 in the first open position or the second open position. The Hall sensor 482 is operable to detect the proximity of the magnet 484.

[0110] When the cover mechanism 401 is in the closed position, the aerosol delivery device 100 is operable in a third mode. In the third mode, the heater 152 is inoperable. Thus, the third mode is a standby mode. The cover mechanism 401 may include a second switch 490 operable to detect that the cover mechanism 401 is in the closed position. The aerosol delivery device 100 may be configured to enter the third mode in response to the second switch 490 determining that the cover mechanism 401 is in the relatively closed position.

[0111] Second switch 490 includes a sensor for detecting the position of at least a portion of cover mechanism 401. Second switch 490 is operable to operate aerosol delivery device 100 in the first mode or the third mode in response to detecting the position of cover mechanism 401. Second switch 490 includes a second Hall sensor 492 and a second magnet 494. In such an embodiment, switch 480 functions as first switch 480 including first Hall sensor 482 and first magnet 484, as described in detail above.

[0112] In an embodiment, the second switch 490 comprises a different sensor configuration, such as one or more of an optical sensor, a potentiometer, and a mechanical switch. The second Hall sensor 492 is fixed to a stationary portion of the cover mechanism 401. The second magnet 494 is fixed to a moving portion of the cover mechanism 401. In this example, the second Hall sensor 492 is fixed to the body 402, and the second magnet 494 is fixed to the actuating member 420. In an embodiment, the second magnet 494 is fixed to the cover member 410.

[0113] The second Hall sensor 492 and the second magnet 494 are positioned such that the second magnet 494 is relatively far from the second Hall sensor 492 when the cover mechanism 401 is in the first open position, and the second magnet 494 is relatively close to the second Hall sensor 492 when the cover mechanism 400 is in the second open position. In an embodiment, these positions may be reversed. In an embodiment, the second magnet 494 may be adjacent to the second Hall sensor 492 in the first open position or the second open position. The second Hall sensor 492 is operable to detect the proximity of the second magnet 494.

[0114] Thus, cover mechanism 401 is operable in three positions, each corresponding to an operating mode of aerosol delivery device 100. A user may move cover mechanism 401 between the three positions by rotating actuation member 420. Moving cover mechanism 401 between the positions changes the operating mode of aerosol delivery device 100. Thus, a user may change the operating mode of aerosol delivery device 100 by rotating actuation member 420. This simplifies operation and control of aerosol delivery device 100. The order and number of these positions may vary. The cover mechanism may be biased to one or more of these positions.

[0115] When the cover mechanism 401 is in the closed position, the aerosol delivery device 100 is operable in a standby mode. Therefore, the term “operable” is understood to include a state in which the aerosol delivery device 100 is not in use. In the standby mode, the heater 152 is not operating, and the aerosol delivery device 100 consumes minimal power. It is expected that the aerosol delivery device 100 will remain in the standby mode when not in use. Preferably, a user's movement of the cover mechanism 401 to the closed position is sufficient to cause the aerosol delivery device 100 to enter the standby mode. This prevents a user from unintentionally leaving the aerosol delivery device 100 in operation, thereby maximizing energy efficiency. To place the aerosol delivery device 100 in the standby mode, the user may be required to move the cover mechanism 401 to the closed position. This reduces the likelihood that a user will leave the cover mechanism 401 in the open position when the aerosol delivery device 100 is not in use, thereby preventing, for example, debris from entering or exiting the chamber 105.

[0116] When the cover mechanism 401 is in the first open position, the aerosol delivery device 100 is operable in a first operating mode. The first operating mode may be a “base mode” configured to provide a first smoking session to a user. Moving the cover mechanism 401 to the second open position by a user may cause the aerosol delivery device 100 to enter a second operating mode. The second operating mode may be a “boost mode” configured to provide a second smoking session to a user. The second smoking session may be more rapid or more powerful than the first smoking session. Thus, a user can intuitively operate the aerosol delivery device 100 depending on whether they desire a more powerful or less powerful smoking session. A user may ascertain whether the aerosol delivery device 100 is operable in the first or second operating mode from the physical position of the cover mechanism 401.

[0117] In this example, the first open position of the cover mechanism 401 is between the closed position and the second open position. That is, the cover mechanism 401 first moves through the first open position before moving into either the closed position or the second open position. In an example where the second open position corresponds to a more intense smoking session, this may provide a particularly intuitive user experience because the intensity of the smoking session may be perceived as gradually increasing from the closed position corresponding to the standby mode to the second position corresponding to the second operating mode. In embodiments, additional positions of the cover mechanism 401 may be provided corresponding to additional operating modes. In embodiments, the cover mechanism 401 may be movable through a continuous range of positions corresponding to a continuous range of operating modes. For example, the actuating member 420 may be operable as a dial for selecting from a continuous range of peak temperatures or heating rates.

[0118] In embodiments, the positional arrangement of the cover mechanism 401 and the corresponding operating modes may vary. For example, the cover mechanism 401 may be operable in multiple closed positions, such as a first closed position and a second closed position, and an open position. The first closed position may correspond to a first operating mode, such as the base mode described above, and the second closed position may correspond to a second operating mode, such as the boost mode described above. This configuration may be particularly suitable for embodiments in which the aerosol delivery device 100 is operable with the article 300 fully received within the chamber 105. For example, the aerosol delivery device 100 may include a mouthpiece in fluid communication with the chamber 105. In yet other examples, the cover mechanism 401 may be operable in multiple closed positions and multiple open positions.

[0119] In an embodiment, the cover mechanism 401 includes a lubricant.

[0120] 7 shows a perspective view from above of the inner actuating component 426. The inner actuating component 426 includes an opening 422. The opening 422 is configured to receive an actuating member mount 442 of the body 402. The inner actuating component 426 slidably engages with the actuating member mount 442. The opening 422 is circular.

[0121] The opening 422 is defined in part by a shoulder 428 on the inner actuating component 426. The shoulder 428 is circumferential; that is, the shoulder 428 extends substantially the entire circumference of the inner actuating component 426. The shoulder 428 on the inner actuating component 426 is configured to be slidably engaged by a clip 443 on the body 402. As the inner actuating component 426 rotates on the body 402, the clip 443 slides along the shoulder 428. The engagement of the clip 443 with the shoulder 428 prevents axial movement of the inner actuating component 426. The shoulder 428 provides a locating feature that engages with the actuating member mount 442.

[0122] Cover mechanism 400 includes a retention mechanism 450. Retention mechanism 450 is configured to removably retain actuating member 420 in each of the first open position, the second open position, and the closed position. In an embodiment, retention mechanism 450 is configured to function in only one of the open position and the closed position.

[0123] The actuation member 420 includes a retention surface 452. The retention surface 452 is defined by the inner actuation component 426. The retention mechanism 450 includes a first open position recess 460, a second open position recess 464, and a closed position recess 462. The recesses 460, 462, and 464 are defined by the retention surface 452.

[0124] The retention mechanism 450 includes a retention member 456. The retention member 456 is joined to the actuation member mount 442 of the main body 402. The retention member 456 is partially received in a bore within the actuation member mount 442. In embodiments, the retention member 456 may comprise a resilient portion of the actuation member mount 442. The retention member 456 protrudes radially. That is, the retention member 456 protrudes in a direction perpendicular to the longitudinal axis. The retention member 456 is positioned to protrude into the first open position recess 460 in the first open position. The retention member 456 is positioned to protrude into the second open position recess 464 in the second open position. The retention member 456 is positioned to protrude into the closed position recess 462 in the closed position.

[0125] The retention member 456 is arranged to move in a radial direction. In an embodiment, the retention member is arranged to deform in a radial direction. The retention member 456 is biased radially outward. Thus, the retention mechanism 450 is biased to the retention state when the actuating member 420 is moved to the first open position and when the actuating member 420 is moved to the second open position. Thus, the retention mechanism 450 is biased to the retention state when the actuating member 420 is moved to the closed position.

[0126] The retaining member 456 is a ball spring arrangement. That is, the retaining member 456 includes a coil spring, a spherical member, and a stopper for retaining the spherical member. The spherical member is formed of nickel-plated steel. Other suitable materials may be used. In another embodiment, the retaining member 456 is a resilient member. The retaining member 456 includes a contact surface. The contact surface is curved. The contact surface is formed of a material that has a relatively low coefficient of friction with the retaining surface 452.

[0127] When the retaining member 456 protrudes into the first open position recess 460, the second open position recess 464, or the closed position recess 462, the cover mechanism 400 is retained in the first open position, the second open position, or the closed position, respectively. It will be understood that the term retained by is intended to mean that a certain level of force must be applied to the cover mechanism 400 to urge it away from the first open position, the second open position, or the closed position so that the cover mechanism 400 does not unintentionally move from the open position or the closed position. In this embodiment, the end of the cam slot 434 provides a travel-limiting stop, thereby preventing the cover mechanism 400 from moving beyond the second open position or the closed position. That is, the cover mechanism 400 is movable only between the second open position and the closed position, and the first open position is between the closed position and the second open position.

[0128] The retaining surface 452 is configured to bias the cover member 410 toward at least one of the relatively open position and the relatively closed position throughout the cover member's range of movement between the relatively open position and the relatively closed position. That is, the retaining surface 452 is configured to bias the cover member 410 toward at least one of the relatively open position and the relatively closed position throughout a first range of movement. It will be appreciated that the retaining surface 452 does not necessarily directly contact the cover member 410. Rather, the retaining surface 452 biases the cover member 410 via other components of the cover mechanism 400.

[0129] The cylindrical portion 452a of the retaining surface 452 extends between the open position recess 464 and the closed position recess 462. The cylindrical portion 452a of the retaining surface 452 is cylindrical and centered on the rotational axis of the actuating member 420. The cylindrical portion 452a of the retaining surface 452 includes a channel 454. The channel 454 extends between the open position recess 460 and the closed position recess 462. The retaining member 456 is positioned to advance within the channel 454 between the open position recess 460 and the closed position recess 462. The retaining surface 452 defines a first edge 454a and a second edge 454b of the channel 454. The retaining member 456 is positioned to abut against the first edge 454a and the second edge 454b.

[0130] The first edge 454a and the second edge 454b converge toward the central region of the channel 454. That is, the distance between the first edge 454a and the second edge 454b is smallest in the central region of the channel 454. The first edge 454a and the second edge 454b diverge toward each end of the channel 454. That is, the distance between the first edge 454a and the second edge 454b is largest adjacent the open position recess 460 and the closed position recess 462. As the retaining member 456 advances from the open position recess 460 or the closed position recess 462 toward the intermediate region of the channel 454, the retaining member 456 is pushed out of the channel 454 by the converging edges 454a, 454b of the channel 454. Therefore, the retaining member 456 advances in a radially inward direction relative to the rotational axis of the actuating member 420. When retaining members 456 are biased in a radially outward direction, retaining members 456 are biased within channels 454. Thus, the bias of retaining members 456 resists movement from the relatively open and relatively closed positions and returns cover mechanism 400 to the relatively open or relatively closed positions in the absence of an external force.

[0131] When the cover mechanism 400 is in the closed position, the retaining member 456 is received in the closed position recess 462. A force applied to the cover mechanism 400 in a clockwise direction is resisted by the ends of the cam slot 434, which act as travel limit stops. If a small force is applied to the cover mechanism 400 in a counterclockwise direction, such as might result from unintentional contact with the actuating member 420, the force is resisted by the bias of the retaining member 456 against the edges 454 a, 454 b of the channel 454. Thus, the cover mechanism 400 is held in the closed position.

[0132] When a greater amount of force is applied to the cover mechanism 400 in a counterclockwise direction, such as by a user intentionally rotating the actuation member 420, the retaining member 456 slides along the channel 454 and moves radially inward against the bias. The spring of the ball spring arrangement is compressed. As the actuation member 420 rotates, the retaining member 456 advances within the channel 454 toward the middle region of the channel 454. Thus, the retaining mechanism 450 can be released by the user moving the actuation member 420 from the closed position. Once the retaining member 456 passes the middle region of the channel 454, the cover mechanism 400 is no longer biased toward the closed position and begins to be biased toward the first open position. In the middle region of the channel, the spring of the ball spring arrangement is maximally compressed. Therefore, the force exerted by the retaining member 456 in a radially outward direction relative to the rotation axis of the actuation member 420 is greatest. At the central region of the channel, the first edge 454a and the second edge 454b reach their maximum convergence point. The central region of the channel represents the inflection point of the first edge 454a and the second edge 454b. Thus, at the midpoint, the force exerted by the retaining member 456 in the radially outward direction does not result in biasing of the cover mechanism 401.

[0133] Thus, the retention mechanism 450 is biased to the closed position over a portion of its range of movement adjacent to the closed position. The retention mechanism 450 is biased to the closed position over approximately 50% of its first range of movement adjacent to the open position. The retention mechanism 450 is biased to the open position over a portion of its range of movement adjacent to the open position. The retention mechanism 450 is biased to the open position over approximately 50% of its first range of movement adjacent to the open position. Thus, the retention mechanism 450 is biased over approximately the entire first range of movement. The only point at which the retention mechanism 450 is not biased is the exact midpoint of the first range of movement. It will be understood that the midpoint does not necessarily have to be, and may be, exactly halfway through the first range of movement. Thus, the cover mechanism 400 returns to the closed position after a small deflection, reducing the likelihood of inadvertently opening or partially opening the cover mechanism 400. Therefore, the time it takes to move the cover mechanism 400 between the open and closed positions can be minimized, and the effort required by the user can also be reduced.

[0134] The retention mechanism 450 includes a second channel 455 extending between the first open position recess 460 and the second open position recess 464. The features and operation of the second channel 455 are substantially similar to the features and operation of the first channel 454.

[0135] The operation of the cover mechanism 400 has been described with reference to one retaining member 456 and three recesses 460, 462, and 464. However, the cover mechanism 400 of FIGS. 3-7 includes two retaining members 456, two first open position recesses 460, two second open position recesses 464, and two closed position recesses 462.
