[0040] [Detailed explanation] As used herein, the term "aerosol-generating material" includes materials that volatilize upon heating, typically in the form of an aerosol. Aerosol-generating materials include any tobacco-containing material, such as one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. Aerosol-generating materials also include other non-tobacco products, which may or may not contain nicotine. Aerosol-generating materials may be in the form of, for example, a solid, liquid, gel, wax, etc. Aerosol-generating materials may also be a combination or blend of materials, for example. Aerosol-generating materials are sometimes known as "smoking materials."

[0041] Devices are known that heat aerosol-generating materials to volatilize at least one component of the aerosol-generating materials, typically without burning or combusting the aerosol-generating materials, to form inhalable aerosols. Such devices may be referred to as "aerosol-generating devices," "aerosol-delivery devices," "non-combustion heating devices," "tobacco heating product devices," or "tobacco heating devices." Similarly, so-called e-cigarette devices exist that vaporize aerosol-generating materials, typically in liquid form (which may or may not contain nicotine). The aerosol-generating material may be in the form of, or provided as, a rod, cartridge, cassette, or other part that can be inserted into the device.

[0042] The aerosol delivery device can receive and heat an article containing an aerosol-generating material. In this context, an "article" is a component that comprises or contains the aerosol-generating material during use and is heated to volatilize the aerosol-generating material and, optionally, other components during use. After a user inserts the article into the aerosol delivery device, the aerosol-generating device may be heated to generate an aerosol that is subsequently inhaled by the user. The article may be of a predetermined size or a specific size configured, for example, to be placed in a heating chamber of a device sized to receive the article.

[0043] 1 shows an example of an aerosol delivery device 100 that generates an aerosol from an aerosol-generating medium / material. Generally, device 100 may be used to heat a replaceable item 110 that contains an aerosol-generating medium, also known as a consumable item, to generate an aerosol or other inhalable medium that is inhaled by a user of device 100.

[0044] Device 100 includes a housing 102 (including an outer cover 108) that encloses and houses various components of device 100. Device 100 has an opening 104 at one end through which an item 110 can be inserted and heated by a heating assembly 200 (see FIG. 2). In use, item 110 may be inserted, in whole or in part, into heating assembly 200 and heated by one or more components of heating assembly 200.

[0045] Device 100 may also include a user-operable control element 112, such as a button or switch, that, when pressed, operates device 100. For example, a user may turn device 100 on by operating switch 112.

[0046] The device 100 defines a longitudinal axis 101 .

[0047] Figure 2 is a schematic cross-sectional front view of device 100 of Figure 1. Device 100 comprises an outer cover 108, a first end member 106, and a second end member 116. Device 100 comprises an aerosol generation assembly 111 that includes a housing 109, a power source 118, and a heating assembly 200. Device 100 further comprises at least one electronics module 122.

[0048] The outer cover 108 forms a portion of the device shell. The first end member 106 is disposed at one end of the device 100, and the second end member 116 is disposed at the opposite end of the device 100. The first and second end members 106, 116 close the outer cover 108 and form a portion of the shell. In embodiments, the device 100 includes a lid (not shown) that can be moved relative to the first end member 106 to close the opening 104 when the item 110 is not in place.

[0049] Device 100 may also include an electrical component, such as connector / port 120, that can accept a cable to charge a battery in device 100. For example, the connector may be a charging port, such as a USB charging port. In some examples, the connector may additionally or alternatively be adapted to transfer data between device 100 and another device, such as a computing device.

[0050] The device 100 comprises a housing 109. The housing 109 is received by an outer cover 108. The aerosol generation assembly 111 comprises a heating assembly 200 into which, during use, all or part of the article 110 can be inserted so that the article 110 is heated by one or more components of the heating assembly 200. The aerosol generation assembly 111 and the power source 118 are mounted in the housing 109. The housing 109 is a unitary component.

[0051] A unitary component refers to a component of device 100 that cannot be separated into two or more components after assembly of device 100. A unitary form refers to two or more features that are formed into a unitary component during manufacturing.

[0052] The first and second end members 106, 116 together at least partially define an end surface of the device 100. For example, the bottom surface of the second end member 116 at least partially defines the bottom surface of the device 100. Alternatively, an edge of the outer cover 108 may define a portion of the end surface. The first and second end members 116 close the open end of the outer cover 108. The second end member 116 is located at one end of the housing 109.

[0053] The end of device 100 closest to opening 104 is considered to be known as the proximal end (or mouth end) of device 100, as it is closest to the user's mouth during use. In use, a user inserts item 110 into opening 104 and operates user-controlled element 112 to initiate heating of the aerosol-generating material and utilize the aerosol generated in the device, thereby causing the aerosol to flow through device 100 along a flow path toward the proximal end of device 100.

[0054] The other end of the device furthest from opening 104 is considered to be known as the distal end of device 100, as it is the end that will be furthest from a user's mouth during use. When a user utilizes the aerosol generated in the device, 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 explained by reference to the relative orientation of such features to one another in the proximal-distal direction along axis 101.

[0055] Power source 118 is a battery, such as a rechargeable or non-rechargeable battery. Suitable examples of batteries include lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically coupled to aerosol generation assembly 111 to provide power as needed and heat the aerosol-generating material under the control of controller 121.

[0056] The power source 118 and the aerosol generation assembly 111 are disposed in an axial arrangement such that the power source 118 is at the distal end of the device 100 and the aerosol generation assembly 111 is at the proximal end of the device 100. Other arrangements are also contemplated.

[0057] The electronics module 122 may include, for example, a printed circuit board (PCB) 123. The PCB 123 may support at least one controller 121, such as a processor, and a memory. The PCB 123 may also include one or more electrical tracks that electrically connect together various electronic components of the device 100. For example, battery terminals 119 a, 119 b may be electrically connected to the PCB 123 so that power can be distributed throughout the device 100. The connector 120 may also be electrically coupled to the battery 118 via the electrical tracks.

[0058] The aerosol-generating assembly 111 is an induction heating assembly that includes various components for heating the aerosol-generating material of the article 110 through an induction heating process. Induction heating is a process for heating an electrical conductor (such as a susceptor) through electromagnetic induction. The induction heating assembly may include an induction element (e.g., one or more inductor coils) and a device for passing a varying current, such as an alternating 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 inside the susceptor. Because the susceptor has an electrical resistance to the eddy currents, the flow of eddy currents against this resistance heats the susceptor through Joule heating. Additionally, if the susceptor includes a ferromagnetic material, such as iron, nickel, or cobalt, heat is also generated by magnetic hysteresis losses in the susceptor, i.e., the varying orientation of magnetic dipoles in the magnetic material as a result of alignment with the varying magnetic field. Induction heating allows for faster heating than, for example, conduction heating, because heat is generated inside the susceptor. Furthermore, no physical contact between the induction heater and the susceptor is required, which allows for greater flexibility in design and application.

[0059] A temperature sensor in the form of a thermocouple 150 is in thermal communication with the susceptor and connected to the electronics module 122. In the illustrated embodiment, a heat transfer plate 140 is disposed between the thermocouple 150 and the susceptor to facilitate thermal communication between the thermocouple 150 and the susceptor (as discussed in more detail below in connection with FIG. 7). In other examples, the plate 140 can be omitted.

[0060] Thermocouple 150 monitors the temperature of the susceptor during use of device 100 and provides this information to electronics module 122. This enables electronics module 122 and controller 121 to monitor and adjust the temperature of the susceptor as needed during use of device 100, for example, by adjusting the amount of power provided by power source 118. Thermocouple 150 can be any suitable thermocouple, such as a platinum-rhodium thermocouple (i.e., Type B).

[0061] Compared to other temperature sensing devices, thermocouple 150 can be more rugged, durable, power efficient, and facilitate accurate temperature measurements. Nevertheless, in other examples within the scope of this disclosure, the temperature sensor can be a resistance temperature detector, a thermistor, an infrared sensor, or any other suitable temperature sensor.

[0062] FIG. 3 is an enlarged partial cross-sectional view of the aerosol generation assembly 111 including the heating assembly 200 and the inductor coil assembly 127.

[0063] The aerosol generation assembly 111 includes an inductor coil assembly 127 and a heating assembly 200. The inductor coil assembly 127 extends around the heating assembly 200. The inductor coil assembly 127 includes a coil support 126. The inductor coil assembly 127 is wrapped around (i.e., surrounds) the heating assembly 200 and includes an inductor coil 124 disposed in a groove 129 defined by the support 126. The inductor coil assembly 127 is fixedly attached to the device housing 102. The coil support 126 may form part of the device housing 102.

[0064] The heating assembly 200 includes a heating element 210 that heats the article 110 during use. In the exemplary embodiment of FIG. 3 , the heating element is a susceptor structure 210 (referred to herein as a “susceptor”). The susceptor 210 in this example is a blade-like susceptor 210. The article 110 is insertable over or around the susceptor 210. The blade-like susceptor 210 may have a constant rectangular cross-section along the majority of its axial length, tapering to a blade tip 212. In other examples, the axial cross-section may vary along the axial length of the susceptor 210 to the blade tip 212.

[0065] Although a blade-shaped susceptor 210 is illustrated, it is understood that any other suitable shape or configuration of the susceptor 210 can be used within the scope of the present disclosure. For example, the susceptor 210 can be pin-shaped, e.g., having a constant circular cross-section along its axial length that tapers to a pin tip, or it can be rod-shaped (e.g., a cylindrical rod or a square rod) having a constant or variable cross-section along its axial length, omitting the tip or taper. In another example, the susceptor 210 can be a tubular member in which the article 110 / aerosol-generating material is received. Such a susceptor is an outer susceptor. In such an example, the susceptor can define a peripheral wall (e.g., an annular wall) that defines at least a portion of a heating chamber in which the article 110 can be received and heated. In such an example, the susceptor surrounds the article 110, rather than the article 110 surrounding the susceptor as in the blade-shaped embodiment described above. It will be appreciated that the cross-sectional profile of the outer susceptor may be formed in a variety of profile shapes.

[0066] In other examples, multiple susceptors (e.g., two or more separate susceptors) may be provided, and may be of different or similar configurations (e.g., pin-shaped, blade-shaped, rod-shaped, or tube-shaped, etc.) as desired.

[0067] The susceptor 210 is made of a conductive material suitable for heating by electromagnetic induction. In this example, the susceptor is made of carbon steel. It will be appreciated that other suitable materials (e.g., ferromagnetic materials such as iron, nickel, or cobalt) may also be used.

[0068] In other embodiments, the mechanism acting as the heating element need not be limited to induction heating. Thus, the mechanism acting as the heating element may be heatable by electrical resistance. To this end, the heating assembly 200 may include electrical contacts for electrically connecting to a device to pass electrical energy through the heating element to electrically activate the heating element. In such embodiments, the inductor coil assembly 127 may be omitted, if desired.

[0069] The inductor coil 124 is constructed from a conductive material. In this example, the inductor coil 124 is constructed from a litz wire / cable that is helically wound to provide the helical inductor coil 124. Litz wire comprises multiple individual wires that are individually insulated and twisted together to form a single wire. Litz wire is designed to reduce skin effect losses in electrical conductors. In the exemplary device 100, the inductor coil 124 is constructed from copper litz wire with a circular cross section. In other examples, the litz wire may have a cross section of other shapes, such as rectangular. The inductor coil 124 can be connected to the PCB 123 to control activation of induction heating using the electronics module 122 and switch 112.

[0070] Additionally, different numbers of inductor coils may be used. For example, while the inductor coil assembly 127 of the heating assembly 200 shown in FIG. 3 includes only one coil 124, it is understood that any number of suitable coils may be featured. Additional coils may be used to provide different heating zones with different heating characteristics for the susceptor 210 (e.g., to provide different heating conditions to different areas along the axial length of the susceptor 210 and / or to provide different heating conditions to the susceptor 210 at different times or for different use cases). Additional coils may also be provided to generate heat in additional susceptors (not shown), which may be disposed in the heating assembly 200.

[0071] The heating assembly 200 also includes a receptacle 230 (shown in more detail in FIGS. 4A and 4B ). The receptacle 230 defines a heating chamber 220 in which the article 110 is received during use. In the illustrated embodiment, the receptacle 230 is an annular body that surrounds the susceptor 210 and provides an annular space between the susceptor 210 and the article 110 that can receive and heat the article 110 during use.

[0072] The coil support 126 and the opening 104 define a device chamber 105 within the device housing 102 that receives and interacts with the receptacle 230 to secure the heating assembly 200 in place. In embodiments, the device chamber 105 is defined by features other than the coil support 126. The coil support 105 defines an interior wall. The interior wall is cup-shaped.

[0073] Receptacle 230 is removably disposed within chamber 105 so that it can be removed and replaced during use. This feature facilitates cleaning of receptacle 230 (and other heating assembly components), as well as replacement of receptacle 230 (and other heating assembly components) in the event of damage or failure.

[0074] In the illustrated example, receptacle 230 is disposed entirely inside chamber 105. In other examples, when receptacle 230 is received in chamber 105, a portion of receptacle 230 (e.g., a lip or flange at its proximal end, etc.) may still extend outside device chamber 105. Thus, in such examples, receptacle 230 may be "partially removably disposed" in chamber 105. This disclosure encompasses all such examples.

[0075] 4A and 4B show the heating assembly 200 and receptacle 230 in more detail. The receptacle 230 includes annular outer and inner walls 231 a, 231 b that are concentric with one another about the longitudinal axis 201 of the heating assembly 200. The outer wall 231 a forms an outer shell. The inner wall 231 b forms an inner shell. As shown in FIGS. 2 and 3, when the heating assembly 200 is inserted into the device housing chamber 205, the longitudinal axis 201 of the heating assembly 200 is substantially coaxial with the longitudinal axis 101 of the device 100.

[0076] The outer wall 231a extends axially from the open / inlet end 233a of the receptacle 230 to the opposite base 233b. The outer wall 231a may define the base 233b itself or may be integrally formed with the base 233b. Alternatively, the base 233b may be separately attached to the outer wall 231a. The outer wall 231a forms a cup. The open / inlet end 233a is so referred to because it is the end of the heating assembly 200 that is located at the inlet 104 of the device 100 when the receptacle is inserted into the device housing chamber 105. Thus, as discussed above in connection with the device 100, the open / inlet end 233a may also be referred to as the proximal end (or mouth end) of the heating assembly 200, while the base 233b may also be referred to as the distal end of the heating assembly 200.

[0077] Base 233b defines an opening 238 through which heating element 210 is received and protrudes (axially). Heating element 210 defines base 214 and a fastening flange 216 around base 214 that is received in opening 238. Fastening flange 216 and base 214 may be press-fit into opening 218; however, any other suitable method of securing heating element 210 in place in receptacle 230 may be used, such as insert molding, an interference fit, a threaded fit, etc. In embodiments, opening 238 may instead be a blind cavity / recess or may be omitted entirely, depending on the fastening method used to secure heating element 210 in place in receptacle 230.

[0078] In the illustrated embodiment, the heating element 210 is fixedly attached to the receptacle 230 such that it is supported as part of the receptacle 230 itself. In this manner, the heating element 210 is removable from the device housing chamber 105 as part of the receptacle 230.

[0079] In an alternative embodiment, the heating element 210 may be fixedly attached to the device housing 102 within the device housing chamber 105 in place of the receptacle 230. In this manner, the receptacle 230 may be removed from the device housing chamber 105 while the heating element 210 remains fixed in place within the device housing chamber 105.

[0080] In any of the above alternatives, the heating element 210 may additionally be separately removable from the device housing 102 and / or receptacle 230 itself. For example, instead of being fixedly attached, the heating element 210 may be removably secured to the receptacle 230 or device housing 102 / chamber 105, such as by threaded reception, bayonet fit reception, or use of a connector on the heating element 210 that can be interference fitted and unscrewed with a corresponding connector on the device housing 102 / chamber 105.

[0081] This may facilitate cleaning and / or replacement of the heating element 210. This improvement in replacing the heating element 210 may be useful when the heating element 210 needs to be replaced due to breakage or failure, but may also be useful when replacing different heating elements 210 for different use cases. For example, in a particular use case, the item 110 may require different shapes / types of heating elements 210.

[0082] The inner wall 231b extends axially from the proximal end 233a toward the base 233b, but does not connect to the base 233b. The inner wall 231b stops axially short of the base 233b, forming an axial gap G between the inner wall 231b and the base 233b. In the illustrated example, the axial gap G provides an annular gap around the heating element 210 between the base 233b and the inner wall 231b.

[0083] Inner wall 231b features a tapered surface 235 at proximal end 233a. Tapered surface 235 tapers at an angle from proximal end 231b toward longitudinal axis 201. Tapered surface 235 may help facilitate insertion of item 110 into heating assembly 200 and heating chamber 220. For example, it may facilitate proper alignment of item 110 around heating element 210 upon insertion into heating chamber 220.

[0084] The outer wall 231a and the inner wall 231b are radially spaced apart and connected by radially extending ribs 236. The ribs 236 secure the inner wall 231b in place within the outer wall 231a. A number of ribs 236 are discretely disposed between the outer wall 231a and the inner wall 231b around the circumference of the walls 231a, 231b. In the illustrated example, four such ribs 236 are evenly spaced around the circumference of the walls 231a, 231b. However, any suitable number and spacing of ribs 236 may be used.

[0085] In the illustrated embodiment, the ribs 236 extend axially the length of the inner wall 231b, although the ribs 236 may extend any suitable axial distance between the walls 231a, 231b sufficient to provide the support necessary to hold the walls 231a, 231b in place and concentric with one another.

[0086] The combination of outer wall 231 a , inner wall 231 b , and rib 236 defines a slot 234 in proximal end 233 a and an axially extending passageway 237 within receptacle 230 .

[0087] The number and size of slots 234 and passages 237 can vary as needed depending on the size, spacing, and number of ribs 236. Furthermore, slots 234 and passages 237 need not be defined at proximal end 233a. For example, rib 236 can be located at any suitable axial location within receptacle 230 (e.g., toward base 233b or midway along the axial length of walls 231a, 231b). Furthermore, slots 234 and passages 237 can alternatively be provided as a single (e.g., substantially annular) slot 234 / passage 237 extending axially between inner and outer walls 231a, 231b.

[0088] In the illustrated embodiment, passageway 237 is used as an airflow passageway that allows airflow communication from the exterior of device 100 to heating chamber 220 and the aerosol-generating material therein during use. Airflow entering from proximal end 233 a through slot 234 and passageway 237 is advantageous because a user is less likely to block airflow to such areas when using device 100.

[0089] Passageway 237 exits into the annular space provided by gap G, which, in use, allows airflow from passageway 237 into heating chamber 220 and into communication with aerosol-generating material / article 110 therein.

[0090] The presence of passageways 237 between inner and outer walls 231 a, 231 b may allow for improved control of and resistance to airflow through passageways 237. For example, airflow modifying features (e.g., airflow restrictors) may be positioned and used in passageways 237 (e.g., extending between walls 231 a, 231 b and / or from ribs 236) so that a more consistent airflow and / or desirable airflow resistance is transmitted through article 110 to a user during use.

[0091] However, it is understood that the present disclosure is not necessarily limited to passages 237 being airflow passages. For example, device 100 and / or heating assembly 200 may provide any suitable alternative or additional airflow passage configuration that provides the airflow necessary for use of device 100. For example, airflow passage(s) may be provided on the side of the device or may be defined between interior wall 231b and article 110 itself. Alternatively or additionally, airflow passage(s) may be directed upward from the distal end of device 100 through base 233b.

[0092] The configuration of the outer and inner walls 231 a, 231 b of the receptacle 230 may facilitate improving the amount of insulation provided between the heating element 210 and the device housing 102 (e.g., compared to a single-walled receptacle 230). Additionally, when the passages 237 are used as airflow passages as described above, further improvement in the amount of insulation provided between the heating element 210 and the device housing 102 may be facilitated (e.g., because (relatively cooler) external airflow may absorb excess heat from the inner and outer walls 231 a, 231 b). The amount of insulation provided by the heating assembly 200 may be an important consideration for the device 100, as it may be necessary to prevent the device 100 from becoming too hot in a user's hand or the temperature from becoming a problem for other device components. Providing an air gap in the receptacle 230 may facilitate improving the amount of insulation required for the device housing, leading to a smaller device housing.

[0093] As discussed above, the receptacle 230 is removably disposed within the chamber 105 so as to allow for removal and replacement during use. In particular, in the illustrated embodiment, the receptacle 230 is configured such that its interaction with the chamber 105 allows it to be engaged and disengaged in response to rotation of the receptacle 230 relative to the device housing 102.

[0094] The receptacle 230 and the device housing 102 include complementary locking mechanisms configured to engage or disengage in response to rotation of the receptacle 230 relative to the device housing 102 .

[0095] In the context of the present disclosure, "engage" refers to an engagement that holds the receptacle 230 in place in the device housing 102 sufficient for use of the device 100, and "disengage" refers to such a release of engagement that allows removal of the receptacle 230 from the device housing 102 (e.g., without requiring removal of other components of the device housing 102 or destruction of parts of the device housing 102).

[0096] 4A, 4B, and 5, the complementary locking mechanism is provided by grooves 240, 242 (or recesses) in the outer surface 232 of the receptacle 230 (i.e., the radially outer surface of the outer wall 231 a) and a corresponding protrusion 244 on the device housing 102. The protrusion 244 extends radially inward from the inner surface of the device housing chamber 105 relative to the longitudinal axis 101 of the device 100.

[0097] 5, when heating assembly 200 is inserted into device housing chamber 105, it is done so with protrusion 244 radially aligned (i.e., relative to longitudinal axis 201) with groove 240. Protrusion 244 and groove 240 are sized so that there is no "engagement" (as described above) with receptacle 230 when protrusion 244 is inserted into groove 240.

[0098] Thereafter, when the heating assembly 200 is rotated about the longitudinal axis 201 relative to the device housing 105, the protrusion 244 rotates from radial alignment with the groove 240 to cross the outer surface 232 and radially align with the groove 242. The protrusion 244 and the groove 242 are sized and shaped to "engage" with the receptacle 230 when the protrusion 244 is inserted into the groove 242. This engagement may be achieved by a sufficient interference fit / contact between the protrusion 244 and the groove 242. For example, the groove 242 defines a ridge 245 that extends radially from the groove 242 and meets the outer surface 232. When the protrusion 244 is aligned with the groove 242, it is axially above the ridge 245 and radially overlaps the ridge 245. Any attempt to remove the receptacle 230 from the device housing chamber 105 with the protrusion 244 in this position (e.g., attempting to pull it out of the chamber 105 along the longitudinal axis 101) will prevent removal because the ridge 245 will make interference contact with the protrusion 244.

[0099] It will be appreciated that subsequent rotation of receptacle 230 from radial alignment with groove 242 / ridge 245 back to radial alignment with groove 240 will result in receptacle 230 being "disengaged" from protrusion 244 and therefore device housing 102. This allows for subsequent removal of receptacle 230 from chamber 105 and device housing 102.

[0100] Grooves 240, 242, in conjunction with outer surface 232 and protrusions 244, may feature tapered / contoured surfaces 241, 243 that can be shaped / formed as needed to provide a particular resistance to rotation between grooves 240, 242. Additionally, the shape, (radial) depth and (axial) height of groove 242 and the corresponding (radial and axial) length of protrusion 244 can also be used to vary the degree of engagement between receptacle 230 and device housing 102 and the associated rotational resistance this provides (e.g., by adjusting the degree of interference fit / contact between protrusion 244 and groove 242 and ridge 245 in the engaged position).

[0101] Adjusting the rotational resistance and degree of engagement in this manner can be used to ensure that the heating assembly 200 is not only sufficiently held in the engaged position for use, but also sufficiently easy to rotate to the disengaged position to facilitate removal. Adjusting these mechanisms can also be used to improve the user-perceived "smoothness" and / or "quality" of the heating assembly 200 rotation and removal process.

[0102] Although four sets of grooves 240, 242 and protrusions 244 are shown spaced circumferentially of the chamber 105 and heating assembly 200, any suitable number and spacing may be used within the scope of this disclosure.

[0103] In the illustrated example, the groove 240 extends the entire axial length of the outer wall 231 a (i.e., from the proximal end 233 a to the base 233 b), which may facilitate ensuring proper axial and radial alignment of the heating assembly 200 during insertion into the device housing 102, as the protrusion 244 can be easily aligned and guided along the groove 240 during the insertion process.

[0104] Additionally, grooves 240 are shown as being radially aligned with ribs 236 relative to longitudinal axis 202. This may provide grooves 240 with additional structural support to resist bending during insertion of heating assembly 200. However, grooves 240 need not be located in this position and may be located in any other suitable radial position.

[0105] Protrusions 244 and grooves 242 are shown at inlet 104 and proximal end 231 a, however, it is within the scope of the present disclosure that protrusions 244 and / or grooves 242 may be located at any suitable axial location within chamber 105 and along outer surface 232, respectively, and the axial length and location of grooves 240 may also be varied accordingly.

[0106] In the illustrated example, grooves 240, 242 are disposed on receptacle 230 and protrusion 244 is disposed on device housing 102, however, within the scope of the present disclosure, it is alternatively possible to dispose grooves 240, 242 on device housing 102 (i.e., chamber 105) and dispose protrusion 244 on receptacle 230 instead.

[0107] Although a particular set of complementary locking mechanisms for achieving releasable rotational engagement in the form of grooves 240, 242 and protrusions 246 between receptacle 230 and device housing 102 has been shown and described above, the present disclosure extends to any other suitable implementation of such rotational complementary locking mechanisms.

[0108] In one example, the complementary locking mechanism can be complementary threads disposed on the receptacle 230 (e.g., on the outer surface 232) and within the chamber 105. In such an example, rotation of the receptacle 230 relative to the device housing 102 can threadably engage and disengage the receptacle 230 from the device housing 102.

[0109] In another example, the complementary locking mechanism may provide a bayonet-fit rotational engagement. In such an example, the receptacle 230 may feature a radially extending pin on the outer surface 232 that is receivable in a corresponding L-shaped slot or recess in the chamber 105. Alignment and rotation of the pin with the L-shaped slot locks the pin in place, thereby "engaging" the receptacle 230 with the device housing 102 (commonly known as a bayonet fit). The L-shaped slot and pin may alternatively be provided on the receptacle 230 and the chamber 105, respectively.

[0110] As alluded to above, it is believed that the releasable rotational engagement between the receptacle 230 and the device housing 102 provided in the present disclosure may facilitate an improved method of removing and replacing the receptacle 230 in the device 100.

[0111] This can provide a convenient and potentially more "satisfying" way for a user to engage and re-engage receptacle 230 with device housing 102. Furthermore, the required alignment between complementary locking features in such a rotational engagement configuration makes it easier to ensure correct and proper alignment of receptacle 230 in device housing 102 for use. This can reduce user frustration and / or the possibility of damage to device 100 and / or receptacle 230 when a user inserts receptacle 230 into device 100 and when replacing receptacle 230.

[0112] In any of the above examples, a biasing member (not shown), such as a spring, may also be disposed within chamber 105 / device housing 102. The biasing member may be configured to be compressed (e.g., by base 233b) in response to insertion of receptacle 230 into device housing chamber 105, thereby providing a biasing force against insertion (but not disengagement when receptacle 230 is placed in an engaged position within housing 102).

[0113] While the biasing member in the above example is used in conjunction with rotational engagement between the receptacle 230 and the device housing 102, it will be understood within the scope of this disclosure that the biasing member may also be used in other examples featuring any other suitable type of releasable engagement between the receptacle 230 and the device housing 102 (e.g., linear / axial mode releasable engagement, push button releasable engagement, etc.).

[0114] The biasing members and resulting biasing force may facilitate subsequent removal of the receptacle 230 from the housing 102, as they may help push the receptacle 230 out of the chamber 105 when disengaged from the housing 102. They may also provide a suitable resistance to insertion of the receptacle 230 into the housing 102, thereby improving the user-perceived "smoothness" and / or "quality" of the receptacle 230 insertion and removal process.

[0115] FIG. 6A illustrates a tool 300 that can be used in combination with the receptacle 230 to aid in the insertion, rotation, and removal of the receptacle 230 from the device housing chamber 105.

[0116] Tool 300 may be provided as part of a kit of parts that includes device 100 and tool 300. The kit of parts may also optionally include one or more items 110 for use with device 100.

[0117] The tool 300 includes a handle 302, a plurality of outer prongs 304, and a plurality of inner prongs 306. The outer prongs 304 are concentrically disposed around the inner prongs 306 relative to the longitudinal axis 301 of the tool 300. The inner and outer prongs 304, 306 extend axially from the handle 302 along the longitudinal axis 301 of the tool 300.

[0118] The inner prong 306 extends axially beyond the outer prong 304 and defines a tip 308 that flares outwardly at an angle away from the longitudinal axis. Additionally, the flared tip 308 may have an increased thickness (radial and axial) compared to the remainder of the inner prong 306.

[0119] The handle 302 may include notches or grooves 303 configured to improve the ergonomics of the handle 302 and facilitate easier gripping and rotation of the handle 302 by a user's hand.

[0120] As shown in FIG. 6B, the outer and inner prongs 304, 306 extend axially into the receptacle 230 and are configured to facilitate insertion and removal of the receptacle 230 from the device housing 102.

[0121] The outer prongs 304 are sized and shaped to be received in corresponding engagement features, which in the illustrated example are slots 234 that extend axially into corresponding passages 237. These features may be able to create frictional or interference contact between the outer prongs 304 and the outer and inner walls 231 a, 231 b.

[0122] The inner prongs 306 extend axially into the heating chamber 220 between the inner wall 231b and the heating element 210 and may be sized and shaped to provide frictional or interference contact between the prongs 306 and the inner wall 231b.

[0123] Inner prong tip 308 is sized and shaped to flare outward into gap G between inner wall 231b and base 233b. Additionally, flared tip 308 may create interference or frictional contact with outer wall 231a and / or inner wall 231b upon insertion of tool 300 into receptacle 230, depending on the degree of flare / particular shape of tip 308.

[0124] When the tool 300 is inserted into the receptacle 230, various interference or frictional contacts between the prongs 304, 306 and the receptacle 230 allow the receptacle 230 to be captured and positioned by the tool 300 (i.e., the interference or frictional contacts are sufficient to hold the receptacle 230 by the tool's prongs 304, 306 when suspended under its own weight).

[0125] Additionally or alternatively to the above, the force of gravity on receptacle 230 when suspended from tool 300 forces inner wall 231b into contact with tip 308, allowing the respective flared shapes to hold receptacle 230 in place.

[0126] When using tool 300 to insert receptacle 230 into device housing 102, handle 302 can be used to provide the user with improved grip and / or leverage for rotating receptacle 230 to engage and disengage from device housing 102.

[0127] Because tool 300 facilitates gripping of receptacle 230 while it is positioned in chamber 105, it may facilitate easier removal of receptacle 230 from device housing 102. It may also facilitate cleaner removal, since the user does not need to touch receptacle 230 itself during removal, thereby avoiding contact with any aerosol-generating materials or other contaminants that may have accumulated therein during use.

[0128] In the illustrated example, there are four outer prongs 304 corresponding to the slots 234 and passages 237, respectively, and two inner prongs 306. However, it will be appreciated that any suitable number of outer and inner prongs 304, 306 may be used, depending, for example, on the particular configuration of the receptacle 230.

[0129] Moreover, there need not be a set of inner and outer prongs; in other examples within the scope of this disclosure, tool 300 may include only one inner or outer prong 304, 306. Also, in other examples, tip 308 may be provided on outer prong 304 in addition to or as an alternative to being provided on inner prong 306.

[0130] Of course, the specific configuration of the prongs may vary widely within the scope of this disclosure depending on the specific configuration of the receptacle 230 and the degree of interference / frictional contact required to retain the tool 300 under its own weight.

[0131] In the illustrated example, slot 234 and passage 237 serve two functions: to provide an airflow passage 237 for airflow from outside device 100 into heating chamber 220, and to accommodate insertion of tool prongs 304. However, in other examples where alternative airflow passages are present in device 100, slot 234 and passage 237 may not be used for airflow, but may still function to allow insertion of tool 300, if desired.

[0132] 7 is a bottom perspective view of receptacle 230 with plate 140 fixedly attached to it. Plate 140 is fixedly attached to base 233b in any suitable manner (e.g., press fit or welding).

[0133] In the illustrated example, the plate 140 is in thermal communication with the base 214 of the heating element 210 by contact.

[0134] Plate 140 may be constructed of any suitable heat-conducting material, such as a metal or alloy, such that heat from heating element 210 is transferred to plate 140 by conduction.

[0135] Thermocouple 150 is located at the bottom of device housing chamber 105 (i.e., at the distal end of chamber 105). When receptacle 230 is inserted into and engaged with device housing chamber 105, plate 140 located in base 233b comes into contact with thermocouple 150. This places plate 140, and thus heating element 210, in thermal communication with thermocouple 150, allowing thermocouple 150 to monitor the temperature of heating element 210 during use, as described above in connection with FIG.

[0136] While in the illustrated example, plate 140 is fixedly attached to receptacle 230 / portion thereof, in other examples plate 140 could alternatively be attached to thermocouple 150 inside device chamber 105 as part of device housing 102. In such examples, base 214 of the heating element would be exposed at base 233b of receptacle 230. Thus, in response to insertion of receptacle 230 into chamber 105, contact of heating element base 214 with plate 140 provides the necessary thermal communication between thermocouple 150 and heating element 210.

[0137] In examples where the heating element 210 is additionally separately removable from the device housing 102, the plate 140 may be fixedly attached to / a portion of the device housing 102 and in thermal communication with the thermocouple 150. In other examples where the heating element 210 is additionally separately removable from the receptacle 230, the plate 140 may be fixedly attached to / a portion of the heating element 210, the receptacle 230, or the device housing 102.

[0138] In such an example, the heating element 210 can still be in thermal communication with the plate 140 and the thermocouple 150 after insertion and engagement into the housing 102 or receptacle 230 .

[0139] In any of the above examples, plate 140 can be replaced by or added to any other suitable intermediate member and shape (e.g., a ring or pin-type connector). In one such example, the intermediate member can instead be a pin that protrudes into the interior of heating element 210.

[0140] Indeed, any combination / number of intermediate members suitable for thermal communication between the heating element 210 and the thermocouple 150 when the receptacle 130 / heating element 210 is inserted into and engaged with the device housing 102 / chamber 105 may be used within the scope of the present disclosure.

[0141] Any other suitable means for providing thermal communication between the heating element 210 and the thermocouple 150 when the receptacle 130 / heating element 210 is inserted into and engaged with the device housing 102 / chamber 105 is also contemplated within the scope of the present disclosure.

[0142] In another example, if desired, a thermally conductive compound such as thermal paste may be additionally used in combination with the heating element 210 and / or the intermediate member(s) to promote good temperature conduction between the heating element 210, the intermediate member(s), and the thermocouple 150.

[0143] In all of the above examples, it is understood that the described configurations allow the heating element 210 to be in thermal communication with the thermocouple 150 in response to the heating element 210 being inserted and engaged with the chamber 105 .

[0144] This is said to provide “removable thermal communication” between the heating element 210 and the thermocouple 150 in response to the insertion and engagement of the heating element 210 with the chamber 105 .

[0145] In other examples where the heating element 210 is inserted into the device housing chamber 105 (instead of the receptacle 230) and fixedly attached to the device housing 102, the thermocouple 150 may be attached directly to the heating element 210 or via a plate 140 or other suitable intermediate member(s) to provide thermal communication therebetween.

[0146] In all of the above examples, thermal communication between thermocouple 150 and heating element 210 can be maintained while isolating and isolating thermocouple 150 from any aerosol-generating material or contaminants that may be present or deposited in heating chamber 220. This may promote improved durability and lifespan of thermocouple 150 and the ability to monitor the temperature of heating element 210. Additionally, plate 140 (or other suitable intermediate member(s)) may still allow for removal of receptacle 230 and / or heating element 210, facilitating improved cleaning / replacement of these components without compromising the functionality / durability of thermocouple 150.

[0147] It should be noted that the above example and its thermocouple solution are equally suitable for aerosol delivery devices in which the receptacle is generally removable from its housing. Thus, the above example and its thermocouple solution need not be limited to the illustrated rotationally removable configuration of receptacle 230 and device housing 102, but may be used in any other example in which the receptacle is removable from the device housing within the scope of this disclosure.

[0148] The above-described embodiments are to be understood as illustrative examples of the present invention. Other embodiments of the present invention are also contemplated. It is to be understood that any feature described with respect to any one embodiment can be used alone or in combination with other described features, and can also be used in combination with any other feature or features of any of the embodiments, or in any other combination of the embodiments. Furthermore, equivalents and modifications not described above may be employed without departing from the scope of the present invention as defined in the appended claims.
