[0044] As used herein, the term "aerosol - forming material" is a material that is capable of forming an aerosol when energized, for example, by heating, radiation, or any other means. The aerosol - forming material can be, for example, in solid, liquid, or gel form, and may or may not contain active substances and / or flavorants. The aerosol - forming material can include any plant - based material (such as a material containing tobacco), and can include, for example, one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes. The aerosol - forming material can also include other non - tobacco products, which may or may not contain nicotine depending on the product. The aerosol - forming material can be, for example, in the form of a solid, liquid, gel, wax, etc. The aerosol - forming material can also be, for example, a combination or mixture of materials.

[0045] The aerosol - forming material can include adhesives and aerosol - forming agents. Optionally, active agents and / or fillers can also be present. Optionally, a solvent (such as water) is also present, and one or more other components of the aerosol - forming material can be soluble or insoluble in the solvent. In some embodiments, the aerosol - forming material is substantially free of plant material. In some embodiments, the aerosol - forming material is substantially free of tobacco.

[0046] The aerosol - forming material can include or be an "amorphous solid". An amorphous solid can be a "monolithic solid". In some embodiments, the amorphous solid can be a dried gel. An amorphous solid is a solid material that can retain some fluid (such as a liquid) within it.

[0047] The aerosol - forming material can include an aerosol - forming film. The aerosol - forming film can include or be a sheet, which can optionally be shredded to form fragments. The aerosol - forming sheet or fragments can be substantially free of tobacco.

[0048] According to the present disclosure, a "non - combustible" aerosol supply system is an aerosol supply system in which the constituent aerosol - forming material of the aerosol supply system (or its components) does not burn or ignite and can deliver at least one substance to a user.

[0049] In some embodiments, the delivery system is a non - combustible aerosol supply system, such as a powered non - combustible aerosol supply system.

[0050] In some embodiments, the non-combustible aerosol supply system is an electronic cigarette, also known as a vaping device or an electronic nicotine delivery system (ENDS), but it should be noted that the presence of nicotine in the aerosol-forming material is not necessary.

[0051] In some embodiments, the non-combustible aerosol supply system is an aerosol-forming material heating system, also known as a heat-not-burn system. An example of such a system is a tobacco heating system.

[0052] In some embodiments, the non-combustible aerosol supply system is a hybrid system that uses a combination of aerosol-forming materials to generate an aerosol, one or more of which aerosol-forming materials can be heated. Each of these aerosol-forming materials can be in the form of, for example, a solid, a liquid or a gel and can contain or can not contain nicotine. In some embodiments, the hybrid system includes a liquid or gel aerosol-forming material and a solid aerosol-forming material. The solid aerosol-forming material can include, for example, tobacco or a non-tobacco product.

[0053] Generally, the non-combustible aerosol supply system can include a non-combustible aerosol supply device and a consumable for use with the non-combustible aerosol supply device.

[0054] In some embodiments, the present disclosure relates to a consumable that includes an aerosol-forming material and is configured to be used with a non-combustible aerosol supply device. These consumables are sometimes referred to as articles in the present disclosure.

[0055] In some embodiments, the non-combustible aerosol supply system (such as its non-combustible aerosol supply device) can include a power source and a controller. For example, the power source can be an electrical power source or an exothermic power source. In some embodiments, the exothermic power source includes a carbon matrix that can be energized to distribute power in the form of heat to an aerosol-forming material or a heat transfer material in proximity to the exothermic power source.

[0056] In some embodiments, the non-combustible aerosol supply system can include an area for receiving a consumable, an aerosol generator, an aerosol-forming area, a housing, a mouthpiece, a filter and / or an aerosol modifier.

[0057] In some embodiments, a consumable for use with a non-combustible aerosol supply device can include an aerosol-forming material, an aerosol-forming material storage area, an aerosol-forming material delivery component, an aerosol generator, an aerosol-forming area, a housing, a wrapper, a filter, a mouthpiece and / or an aerosol modifier.

[0058] An aerosol generating device can receive an article comprising an aerosol generating material for heating. The "article" in the context is a component that includes or contains an aerosol generating material (which is heated to volatilize the aerosol generating material) in use, and optionally other components in use. A user can first insert the article into the aerosol generating device and then heat the article to generate an aerosol, which the user then inhales. The article can have, for example, a predetermined or specific size and is configured to be placed in a heating chamber of the device, the size of which is designed to receive the article.

[0059] Figure 1 An aerosol supply system 101 is shown, which includes an aerosol supply device 100 for generating an aerosol from an aerosol generating material and a consumable 200. The consumable 200 is an article containing an aerosol generating material. The device 100 can be used to heat a replaceable consumable 200 containing an aerosol generating material to generate an aerosol or other inhalable medium for inhalation by a user of the device 100. In use, the consumable 200 is inserted into the device 100 for heating.

[0060] The device 100 includes a body 110. The body 110 surrounds and houses the various components of the device 100. The body 110 defines the housing of the device. The body 110 defines the outer surface that is contacted by a user of the device 100. An opening 132 is formed in one end of the body 110 through which the consumable 200 can be inserted to be heated by an aerosol generator 116. In use, the consumable can be fully or partially inserted into a heating zone 124 where the consumable can be heated by one or more components of the aerosol generator 114. The aerosol generator 114 includes a heating assembly 120.

[0061] The device 100 can also include a user-operable control element (not shown), such as a button or a switch, which operates the device 100 when pressed. For example, a user can turn on the device 100 by operating the switch.

[0062] The device 100 includes an electronic assembly 112. The electronic assembly 112 is disposed in the body 110. The electronic assembly 112 includes a power source. The power source can be, for example, a battery 150, such as a rechargeable battery or a non-rechargeable battery. Examples of suitable batteries include, for example, lithium batteries (such as lithium-ion batteries), nickel batteries (such as nickel-cadmium batteries), and alkaline batteries. The battery is electrically connected to the heating assembly 120 to supply electric power for heating the aerosol generating material when needed and under the control of a controller.

[0063] The electronic assembly 112 includes an electronic module. The electronic module can include a printed circuit board assembly (PCBA) 114 (as Figure 2 and Figure 3as shown). The PCBA 114 may include, for example, a printed circuit board (PCB) that supports at least one controller (such as a processor) and a memory. The PCB may also include one or more electrical traces to electrically connect the various electronic components together. The battery terminals may be electrically connected to the PCB such that power may be distributed throughout the device 100. The heating assembly 120 is connected to the electronic components.

[0064] The end of the device 100 closest to the opening 132 may be referred to as the proximal end (or mouth end) 105 of the device 100 as it is closest to the user's mouth during use. During use, the user inserts the consumable 200 into the opening 132, operates the aerosol generator 114 to start heating the aerosol-generating material, and inhales the aerosol generated in the device 100. This causes the aerosol to flow through the device 100 along a flow path towards the proximal end 105 of the device 100.

[0065] The other end of the device furthest from the opening 132 may be referred to as the distal end 106 of the device 100 as it is the end furthest from the user's mouth during use. When the user inhales the aerosol generated in the device, the aerosol flows in the direction towards the proximal end 105 of the device 100. The terms "proximal" and "distal" applied to the features of the device 100 will be described by reference to the relative positioning of these features relative to each other in the proximal-distal direction along the longitudinal axis 134.

[0066] The consumable 200 is inserted into and removed from the device 100 through the opening 132. The heating assembly 120 may include an inductive heating system that includes a magnetic field generator that includes an inductive coil assembly. The heating assembly 120 may include a heating element. The heating element is also referred to as a susceptor. The consumable may include a susceptor or a heating element that can be heated by the heating assembly 120.

[0067] The heating assembly 120 forming part of the aerosol generator 116 may be an induction heating assembly and include various components that heat the aerosol generating material of the article via an induction heating process. Induction heating is the process of heating a conductive object (such as a susceptor) by electromagnetic induction. The induction heating assembly may include an induction element (e.g., one or more induction 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 passes through a susceptor appropriately positioned relative to the induction element and generates eddy currents inside the susceptor. The susceptor has a resistance to the eddy currents, and thus the eddy currents flow against the resistance so that the susceptor is heated by Joule heating. In the case where the susceptor comprises a ferromagnetic material (such as iron, nickel or cobalt), heat may also be generated by hysteresis losses in the susceptor, i.e., heat is generated by the changing orientation of magnetic dipoles in the magnetic material due to their alignment with the varying magnetic field. In induction heating, heat is generated inside the susceptor, allowing rapid heating, compared to heating by conduction, for example. Furthermore, no physical contact is required between the induction heater and the susceptor, allowing for increased freedom of construction and application.

[0068] The heating element may be hollow and thus define at least a portion of a receiving portion within which the aerosol generating material is received. For example, the article may be inserted into the heating element. The heating element is tubular and has a circular cross-section. The heating element has a substantially constant diameter along its axial length. In an embodiment, the heating element protrudes in the receiving portion. Other arrangements are contemplated.

[0069] The heating element is formed of an electrically conductive material suitable for heating by electromagnetic induction. The susceptor in this example is formed of carbon steel. It will be appreciated that other suitable materials may be used, for example ferromagnetic materials such as iron, nickel or cobalt. The heating element may be an elongated member protruding in a heating zone defined by the receiving portion.

[0070] In other embodiments, the features used as heating elements may not be limited to being inductively heated. Thus, the features used as heating elements may be resistively heatable. Thus, the aerosol generator 116 may include electrical contacts for electrically connecting to a device to electrically activate the heating element by passing electrical energy through the heating element.

[0071] The consumable 200 is inserted into the device 100 through the opening 132 and into the receiving portion 130. The receiving portion 130 receives the consumable 200. The receiving portion 130 defines a heating zone 124 in which the consumable 200 is heated. The receiving portion 130 defines a longitudinal axis 134 along which the consumable 200 is aligned. The heating assembly 120 is arranged to heat the consumable 200 when the consumable 200 is received in the receiving portion 130. The heating assembly can be an induction heater assembly or a resistive heater assembly.

[0072] The battery 150 is disposed in the body 110. The battery 150 is offset from the longitudinal axis 134 of the receiving portion 130 and thus from the heating assembly 120. The thermal insulation device 160 is disposed between the heating assembly 120 and the battery 150. The thermal insulation device 160 is arranged to control the heat transfer between the heating assembly 120 and the battery 150 serving as a power source.

[0073] Figure 2 and Figure 3 The system 101 is shown in more detail. The heating assembly 120 includes a coil 122 surrounding the receiving portion 130. In an embodiment using induction heating, the coil is an induction coil. In an embodiment using resistive heating, the coil 122 in the embodiment is a resistive heating coil. The configuration of the coil can be different. In an embodiment, the coil is a helical coil. In an embodiment, the coil is omitted, especially in the case of using a different resistive heating device. In an embodiment, a resistive heating element (such as the coil 122) heats the receiving portion 130. In an embodiment, the receiving portion 230 itself is resistively heated.

[0074] The coil 122 or other heating element device is connected to a printed circuit board assembly (PCBA) 140, and the printed circuit board assembly is connected to the electronic assembly 112. The PCBA 140 and the battery 150 are disposed adjacent to the heating assembly 120. The thermal insulation device 160 is disposed between the battery 150 and the heating device 120. In this embodiment, the thermal insulation device 160 is disposed between the battery 150 and the PCBA 140. By disposing the thermal insulation device between the battery and the PCBA 140, the number of connections passing through the thermal insulation device can be minimized. In an embodiment, the thermal insulation device can be disposed between the heating assembly and the PCBA.

[0077] By arranging a combination of layers in the heat insulation device 160, the layers can act together synergistically to maximize heat dissipation on the heat insulation device 160. Arranging the heat distribution layer 163 together with one or more heat insulation layers helps to minimize the required thickness of the heat insulation device 160 by reducing hot spots along the heat insulation device 160, and thus minimize the maximum temperature difference required to be obtained on or across each heat insulation layer. Therefore, the thickness of the heat insulation device 160 can be minimized.

In an embodiment, at least one of the heat insulation layers 161, 162 serves as a support. The first heat insulation layer 161 can form a substrate. The thermal conductivity of each heat insulation layer 161, 162 is less than 0.010 W / m·K, less than 0.020 W / m·K, less than 0.030 W / m·K or less than 0.040 W / m·K.

[0080] The heat distribution layer 163 can be a coating. The coating can be provided on one of the first heat insulation layer 161, the second heat insulation layer 162, and the heat reflection layer 164.

[0081] The heat-reflecting layer 164 contains metal. In an embodiment, the heat-reflecting layer is a coating.

[0082] In Figure 2 and Figure 3 embodiments, the heat distribution layer 163 and the heat-reflecting layer 164 are located between the first thermal insulation layer 161 and the second thermal insulation layer 162. The first thermal insulation layer 161 and the second thermal insulation layer 162 sandwich the heat distribution layer 163 and the heat-reflecting layer 164. One of the heat distribution layer 163 and the heat-reflecting layer 164 can be omitted. The thermal control layers are attached to each other.

In an embodiment, the thermal insulation device can include two or three layers, which include two or three of the first thermal insulation layer, the second thermal insulation layer, the heat distribution layer, and the heat-reflecting layer. The thermal control layers can be in direct contact with each other, or can be spaced apart with an air gap therebetween.

The battery 150 can be spaced apart from the battery carrier 152 to provide an air gap between the battery 150 and the battery carrier 152, thereby providing further thermal insulation for the battery 150.
