Description

Technical Field

[0001] This invention relates to an aerosol generating component, particularly an aerosol generating component for a non-combustible aerosol supply system. The invention also relates to an aerosol generating assembly including the aerosol generating component, an aerosol generating system including the aerosol generating component or the aerosol generating assembly, and a method for forming the aerosol generating component. Background Technology

[0002] Non-combustible aerosol supply systems that generate aerosols for user inhalation are known. Such systems typically include an aerosol generating component capable of converting atomizable materials into aerosols. In some cases, the generated aerosol is a condensed aerosol, where the atomizable material is first vaporized and then condensed into an aerosol. In other cases, the generated aerosol is produced by the atomization of atomizable materials. This atomization can be mechanically initiated, for example by subjecting the atomizable material to vibration to form small particulate material entrained in the airflow. Alternatively, this atomization can be achieved electrostatically or otherwise (e.g., by using pressure).

[0003] Since such aerosol supply systems are designed to generate aerosols for users to inhale, the characteristics of the generated aerosols should be considered. These characteristics may include aerosol particle size, the total amount of aerosols generated, etc.

[0004] In cases where aerosol delivery systems are used to simulate the smoking experience (e.g., as e-cigarettes or similar products), control over these different characteristics is particularly important because users may expect to generate specific sensory experiences from the use of the system.

Detailed Implementation

[0153] This document discusses / describes aspects and features of certain embodiments and implementations. Some aspects and features of certain embodiments and implementations can be conventionally implemented, and for the sake of brevity, these aspects and features are not discussed / described in detail.

Solid aerosol generating materials may include, for example, tobacco or non-tobacco products.

[0155] Throughout the following description, the terms "e-cigarette" and "electronic cigarette" may sometimes be used. However, it should be understood that these terms are used interchangeably with the non-combustible aerosol (vapor) supply system described above.

[0156] In some embodiments, this disclosure relates to consumables for containing aerosol-generating materials, and these consumables are configured for use with a non-flammable aerosol supply device. Throughout this disclosure, these consumables may be referred to as “articles of manufacture”.

[0157] This non-combustible aerosol supply system typically comprises an apparatus section (also referred to as the "apparatus" in this text) and a consumable / product section (also referred to as the "product" in this document). The apparatus section typically includes a power source and / or a controller. The power source can typically be an electrical power source, such as a rechargeable battery.

[0158] In some embodiments, the non-combustible aerosol supply system may include a region for receiving or engaging the consumable / article (the region may be included in or within the device), an aerosol generator (which may or may not be included in or within the consumable / article), an aerosol generation region (which may be included in or within the consumable / article), a housing, a nozzle, a filter, and / or an aerosol modifier.

[0159] In some embodiments, consumables / articles used with a non-combustible aerosol supply system may include aerosol generating material, an aerosol generating material storage area (also referred to herein as a "reservoir for atomizable material"), an aerosol generating material delivery component (e.g., a core, such as a gasket), an aerosol generator (also referred to herein as an "aerosol generating component"), an aerosol generating area (also referred to herein as an "aerosol generating chamber"), a housing, a package, a filter, a nozzle, and / or an aerosol modifier.

[0160] The systems described herein typically generate inhalable aerosols through the vaporization of aerosol-generating materials. These aerosol-generating materials may comprise one or more active ingredients, one or more flavoring agents, one or more aerosol-forming materials, and / or one or more other functional materials.

[0161] Aerosol-generating materials may be in liquid or gel form, and may or may not contain active substances and / or flavorings.

[0162] As used herein, the term "active substance" can refer to a physiologically active substance, which is a material intended to achieve or enhance a physiological response. Active substances can be, for example, selected from nutritional supplements, cognitive enhancers, and psychoactive substances. Active substances can be naturally occurring or synthetically obtained.

[0163] Aerosol forming agent materials may include one or more components capable of forming aerosols. In some embodiments, the aerosol forming agent material may include one or more of the following: glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butanediol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl caprylate, triethyl citrate, glyceryl triacetate, a mixture of glyceryl diacetate, benzyl benzoate, benzyl phenylacetate, glyceryl tribocylate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0164] One or more other functional materials may include one or more of the following groups: pH adjusters, colorants, preservatives, binders, fillers, stabilizers, and / or antioxidants.

[0165] As used herein, the term "component" refers to a part, segment, unit, module, assembly, or the like of an electronic cigarette or similar device that may contain several smaller parts or elements within an outer housing or wall. An electronic cigarette may be formed or constructed from one or more such components, and these components may be removably or detachably connected to each other, or may be permanently joined together during manufacturing to define the entire electronic cigarette. This disclosure applies to, but is not limited to, systems comprising two components detachably connected to each other, configured, for example, to hold a consumable / produced component (also referred to herein as a "cartridge" or "cartomiser") of aerosol-generating material, and a device / control unit having a battery for providing power to operate elements for generating vapor from the aerosol-generating material.

[0166] Figure 1 This is a height schematic diagram (not drawn to scale) of an exemplary non-combustible aerosol supply system (such as electronic cigarette 10). Electronic cigarette 10 has a generally cylindrical shape extending along a longitudinal axis indicated by dashed lines and includes two main components, namely, a control or power supply component or segment 20 (which may be referred to herein as a device) and a cartridge assembly or segment 30 (which may be referred to herein as an “article,” “consumable,” “atomizer,” or “cartridge”) that operates as a vapor-generating component.

[0167] Article 30 includes a storage chamber (also referred to herein as a “reservoir”) 3 containing an atomizable material, which includes, for example, a liquid formulation from which an aerosol is to be generated. The liquid formulation may or may not contain nicotine. As an example, the atomizable material may include about 1% to 3% nicotine and 50% glycerin, with the remainder comprising primarily propylene glycol, and may also include other components such as water or flavoring agents. The storage chamber 3 is in the form of a storage canister, a container or receiver in which the atomizable material can be stored, allowing the atomizable material to move and flow freely within the boundaries of the container or receiver (if it is a liquid). Alternatively, the storage chamber 3 may contain a large amount of absorbent material, such as cotton filler or glass fiber, to hold the atomizable material within a porous structure. The storage chamber 3 may be sealed during manufacturing after filling so that it is disposable after the atomizable material has been consumed, or it may have an inlet port or other opening through which new atomizable material can be added. Article 30 also includes an electrically operated aerosol generating component 4 located outside the storage chamber 3 for generating an aerosol through the vaporization of the atomizable material. In many embodiments, the aerosol generating component is a heating element (heater) that heats the atomizable material by the passage of an electric current (via resistance or induction heating) to raise the temperature until it evaporates. An aerosol generating material transport component ( Figure 1(Not shown in the diagram), for example, a liquid conduit arrangement (such as a wick or other porous element) can be provided to deliver atomizable material from storage chamber 3 to aerosol generating component 4. The aerosol generating material transport component may have one or more sections located inside storage chamber 3 to absorb atomizable material and transfer it by wicking or capillary action to other sections of the aerosol generating material transport component in contact with aerosol generating component 4. The atomizable material is thus vaporized and replaced by new atomizable material delivered to aerosol generating component 4 by the aerosol generating material transport component.

[0168] The combination of a heater and a coil, or other arrangement of components performing the same function, is sometimes referred to as an atomizer or atomizer assembly (which is referred to herein as an "aerosol generating assembly"). Figure 1 Compared to a highly schematic representation, various designs are possible, in which components can be arranged differently. For example, the core can be a component completely separate from the aerosol generating components.

[0169] In some cases, the aerosol generating material transport component 4 (e.g., a liquid conduit) for delivering the liquid used to generate vapor can be at least partially formed by one or more slots, tubes, or channels between the storage chamber and the aerosol generating component, the slots, tubes, or channels being narrow enough to support capillary action to draw the source liquid from the storage chamber and deliver it for vaporization. Typically, the atomizer can be considered as the aerosol generating component 4, which is capable of generating vapor from the atomizable material supplied to the atomizer, and the aerosol generating material transport component (e.g., a liquid conduit), which is capable of conveying or transferring liquid from the storage chamber 3 or a similar liquid reservoir to the aerosol generating component by capillary force.

[0170] Typically, the aerosol generating component is at least partially located within the aerosol generating chamber, which forms part of the airflow channel through the electronic cigarette / system. Vapor generated by the aerosol generating component is driven into the chamber, and as air flows through the chamber, above and around the aerosol generating component, it collects the generated vapor, thereby condensing it to form the desired aerosol.

[0171] return Figure 1 The cartridge assembly 30 also includes a mouthpiece 35 with an opening or air outlet through which the user can inhale aerosol generated by the aerosol generating component 4 and delivered through an airflow channel.

[0172] The power supply unit 20 includes a battery 5 (also referred to herein as a battery, and which may be rechargeable) to provide power to the electrical components of the electronic cigarette 10, particularly the aerosol generating unit 4. Additionally, a printed circuit board 28 and / or other electronic devices or circuits are present for overall control of the electronic cigarette 10. When vapor is needed, for example, in response to a signal from a pressure sensor or airflow sensor (not shown), the control electronics / circuit connects the aerosol generating element 4 to the battery 5. The pressure sensor or airflow sensor detects inhalation on the system 10, during which air enters through one or more air inlets 26 in the wall of the power unit 20 to flow along an airflow channel. When the aerosol generating unit 4 receives power from the battery 5, it evaporates the atomizable material supplied from the storage chamber 3 to generate an aerosol, which is then inhaled by the user through an opening in the mouthpiece 35. As the user inhales on the mouthpiece 35, the aerosol is transported to the mouthpiece 35 along an airflow channel (not shown) that connects the air inlet 26 to the air outlet. Therefore, the airflow path through the electronic cigarette is defined between the air inlet (which may or may not be located in the power supply unit 20) and the atomizer, and extends to the outlet at the mouthpiece. In use, the airflow direction along this airflow path is from the air inlet to the air outlet, such that the atomizer can be described as being arranged downstream of the air inlet and upstream of the air outlet.

[0173] In this particular embodiment, the power supply component 20 and the cartridge assembly 30 are separate components that can be detached from each other by separating them in a direction parallel to the longitudinal axis, such as... Figure 1 As indicated by the solid arrows in the diagram. When the device 10 is in use, components 20 and 30 are engaged together by mating engagement elements 21 and 31 (e.g., screws, magnetic, or bayonet fittings), which provide mechanical and electrical connectivity between the power supply section 20 and the cartridge assembly 30. However, this is only an exemplary arrangement, and different components may be distributed differently between the power supply section 20 and the cartridge assembly 30, and may include other components and elements. The two sections 20 and 30 can be as follows: Figure 1The atomizer is connected end-to-end in a longitudinal configuration or in a different configuration (such as parallel or side-by-side arrangement). The non-combustible aerosol supply system 10 may or may not be generally cylindrical and / or have a generally longitudinal shape. Any segment or two segments may be intended to be discarded and replaced when depleted (e.g., when the reservoir is empty or the battery is depleted), or intended for multiple uses by actions such as refilling the reservoir, recharging the battery, or replacing the atomizer. Alternatively, the electronic cigarette 10 may be an integrated device (disposable or refillable / rechargeable) that cannot be divided into two or more parts, in which case all components are contained within a single housing or casing. Embodiments of the invention are applicable to any of these configurations and other configurations that will be recognized by those skilled in the art.

[0174] As described above, one type of aerosol generating component (such as a heating element) that can be used in the atomizing portion (a component configured to generate vapor from a source liquid) of an electronic cigarette 10 combines heating and liquid delivery functions through both conductivity (resistance) and porosity. It should be noted here that conductivity (resistance) refers to a component having the ability to generate heat in response to the flow of an electric current therein. This flow can be imparted by so-called resistance heating or induction heating. The aerosol generating component can be in sheet form, i.e., a planar shape having a thickness many times smaller than its length or width. This planar aerosol generating component can define a curved plane, and in these cases, the planar aerosol generating component forming plane refers to an imaginary plane that forms the best-fitting plane through the component.

[0175] Aerosol generating components may include pores and / or gaps of appropriate size to provide capillary force for wicking atomizable materials (e.g., liquids). Therefore, aerosol generating components can also be considered porous to facilitate the absorption and distribution of atomizable materials (e.g., liquids). Furthermore, the presence of pores and / or gaps can mean that air can permeate through the aerosol generating component. Moreover, at least a portion of the aerosol generating component is conductive and therefore suitable for resistance heating, whereby an electric current flowing through a resistive material generates heat.

[0176] An aerosol generating component (e.g., planar and / or sheet-like) may be disposed within a non-combustible aerosol supply system (e.g., an electronic cigarette) such that the aerosol generating component is located within an aerosol generating chamber forming part of an airflow channel. The aerosol generating component may be oriented within the chamber such that airflow through the chamber flows in a surface direction (i.e., substantially parallel to the plane of the aerosol generating component). Embodiments of this configuration can be found in WO 2010 / 045670 and WO 2010 / 045671, the contents of which are incorporated herein by reference in their entirety. Air can thus flow through the aerosol generating component and vapor is collected. Thus, aerosol generation becomes effective. In an alternative embodiment, the aerosol generating component may be oriented within the chamber such that airflow through the chamber flows in a direction substantially transverse to the surface direction (i.e., substantially orthogonal to the plane of the aerosol generating component). Embodiments of this configuration can be found in WO 2018 / 211252, the contents of which are incorporated herein by reference in their entirety.

[0177] Aerosol generating components can have high porosity. High porosity ensures that the heat generated by the aerosol generating component is primarily used for liquid evaporation and achieves high efficiency. A porosity greater than 50% is conceivable. In one embodiment, the porosity of the aerosol generating component is 50% or greater, 60% or greater, or 70% or greater.

[0178] The aerosol generating component can form a generally flat structure, including first and second surfaces. The generally flat structure can take the form of any two-dimensional shape, such as a circle, semicircle, triangle, square, rectangle, and / or polygon. The aerosol generating component can have a uniform thickness.

[0179] When the aerosol generating component is formed of a resistive material, current is allowed to flow through it to generate heat (so-called Joule heating). The resistance of the aerosol generating component can be appropriately selected. For example, the aerosol generating component can have a resistance of 2 ohms or less, such as 1.8 ohms or less, 1.7 ohms or less, 1.6 ohms or less, 1.5 ohms or less, 1.4 ohms or less, 1.3 ohms or less, 1.2 ohms or less, 1.1 ohms or less, 1.0 ohms or less, 0.9 ohms or less, 0.8 ohms or less, 0.7 ohms or less, 0.6 ohms or less, or 0.5 ohms or less. Parameters of the aerosol generating component, such as material, thickness, width, length, porosity, etc., can be selected to provide the desired resistance. Relatively low resistance will help draw higher power from the power source, which can be beneficial for producing a high atomization rate. On the other hand, the resistance should not be so low as to compromise the integrity of the aerosol generator. For example, the resistance can be no less than 0.5 ohms.

[0180] In one aspect of this disclosure, an aerosol generating component 100 is provided as part of a non-combustible aerosol supply system, the aerosol generating component 100 including a carbon allotrope 101 loaded on an electrically insulating substrate 102.

[0181] Figures 2 to 9 An embodiment of the aerosol generating component 100 is shown.

[0182] It has been found that, in the case of a non-combustion aerosol supply system, the aerosol generating component 100 exhibits the desired heating and atomization performance.

[0183] The carbon allotrope 101 is loaded onto the electrically insulating substrate 102. In this way, the carbon allotrope 101 is loaded directly or indirectly onto the electrically insulating substrate 102.

[0184] The electrically insulating substrate 102 may be porous. Alternatively, the electrically insulating substrate 102 may be non-porous.

[0185] The electrically insulating substrate 102 may include one or more layers. At least one layer may be porous. At least one layer may be non-porous. For example, at least one layer may be porous and at least one layer may be non-porous.

[0186] At least one of these layers can be formed as a coating.

[0187] The electrically insulating substrate 102 may include at least two layers, wherein the layer in direct contact with the carbon allotrope 101 is porous, and at least one other layer is non-porous.

[0188] The electrically insulating substrate 102 may include at least two layers, wherein the layer in direct contact with the carbon allotrope 101 is non-porous, and at least one other layer is porous.

[0189] The electrically insulating substrate 102 can be made of any suitable conductive material. Specifically, the electrically insulating substrate 102 can be thermally insulating (in this case, the substrate can be referred to as "electrically insulating and thermally insulating substrate 102"). The electrically insulating substrate 102 may have a surface area not exceeding 5 Wm. -1 k -1 Thermal conductivity. The electrically insulating substrate 102 may have a thermal conductivity of no more than 3 W / m². -1 k -1 Thermal conductivity.

The electrically insulating substrate 102 may have a thermal conductivity of not more than 1 W / m. -1 k -1 Thermal conductivity. The electrically insulating substrate 102 may have a thermal conductivity of not more than 0.5 W / m. -1 k -1The thermal conductivity. The electrically insulating substrate 102 may have a thermal conductivity of not more than 0.2 W / m. -1 k -1 The thermal conductivity. The electrically insulating substrate 102 may have a thermal conductivity of not more than 0.1 W / m. -1 k -1 Thermal conductivity.

[0190] For example, the electrically insulating substrate 102 can be selected from the group consisting of plastics, glass, paper, and ceramics. For example, when the electrically insulating substrate 102 comprises one or more layers, each layer can be independently selected from plastics, glass, paper, and ceramics.

[0191] The plastic may be selected from polysulfone (PSU), poly(ether sulfone) (PES), polyimide (PI), poly(phenylene sulfide) (PPS), polyether ether ketone (PEEK), and polyether ketone (PEK). In some embodiments, the polyimide (PI) is selected from polyether imide (PEI) and polyamide-imide (PAI). In some embodiments, the polyimide is poly(4,4'-oxodiphenylene-pyromellitictetraimide). Poly(4,4'-oxodiphenylene-pyromellitictetraimide) is commercially available from DuPont under the trade name Kapton® HN (and other Kapton® products).

[0192] The glass can be selected from silicate glass and non-silicate glass. In some embodiments, the silicate glass is borosilicate glass or quartz glass (fused silica). The glass can be flexible. The glass can be non-porous.

[0193] The electrically insulating substrate 101 (e.g., at least one layer thereof) may have a porous structure formed by pillars and interstitial pores (also referred to herein as pores and / or gaps). A carbon allotrope 101 may be formed on the pillars to form a coating. For example, the interstitial pores of the coated electrically insulating substrate may have an average pore diameter of 0.5 to 40 µm (although this can vary). The average pore diameter may be a median pore diameter or a mean pore diameter. The average pore diameter can be determined by methods including (but not limited to) mercury porosimetry or gas adsorption. These methods are well known to those skilled in the art.

[0194] The electrically insulating substrate 102 can be formed as a sheet (which can be curved or substantially planar). The electrically insulating substrate 102 can be substantially flat. In some embodiments, the electrically insulating substrate 102 can be formed as a plate, strip (e.g., ...). Figure 2 , 3 (As shown in 5A, 5B, 6A, and 6B) or a rod. For example... Figures 2 to 9 As shown, the electrically insulating substrate 102 may be elongated.

[0195] In some embodiments, the cross-sectional area of ​​the electrically insulating substrate 102 perpendicular to its longitudinal extension direction (e.g., the length direction) is polygonal (e.g., square, rectangular, or triangular). Alternatively, the cross-sectional area of ​​the electrically insulating substrate 102 perpendicular to its longitudinal extension direction (e.g., the length direction) is curved (e.g., circular, oval, or elliptical).

[0196] In some embodiments, the electrically insulating substrate 102 has a thickness from 100 µm to 4 mm. In some embodiments, the electrically insulating substrate 102 has a thickness from 200 µm to 3 mm.

[0200] In some embodiments, the carbon allotrope 101 has a length of 1 mm to 50 mm. In some embodiments, the carbon allotrope 101 has a length of 2 mm to 40 mm. In some embodiments, the carbon allotrope 101 has a length of 5 mm to 30 mm. In some embodiments, the carbon allotrope 101 has a length of 10 mm to 30 mm. In some embodiments, the carbon allotrope 101 has a length of 10 mm to 25 mm. In some embodiments, the carbon allotrope 101 has a length of 10 mm to 20 mm. In some embodiments, the carbon allotrope 101 has a length of 12 mm to 18 mm.

[0201] In some embodiments, the carbon allotrope 101 has a width from 0.5 mm to 50 mm. In some embodiments, the carbon allotrope 101 has a width from 0.5 mm to 20 mm. In some embodiments, the carbon allotrope 101 has a width from 0.5 mm to 10 mm. In some embodiments, the carbon allotrope 101 has a width from 0.5 mm to 5 mm. In some embodiments, the carbon allotrope 101 has a width from 1 mm to 50 mm. In some embodiments, the carbon allotrope 101 has a width from 1 mm to 20 mm. In some embodiments, the carbon allotrope 101 has a width from 1 mm to 10 mm. In some embodiments, the carbon allotrope 101 has a width from 1 mm to 5 mm. In some embodiments, the carbon allotrope 101 has a width from 1 mm to 3 mm.

[0202] The aerosol generating component 100 may include capillary structures. The capillary structures provide a surface that facilitates the efficient transport of atomizable material through the overall structure of the aerosol generating component 100 and / or through one or more layers of the carbon allotrope 101.

[0203] In some embodiments, the carbon allotrope 101 includes a capillary structure. Alternatively or additionally, the electrically insulating substrate 102 may include a capillary structure. For example, as described above, the capillary structure may be provided by the porous structure of the electrically insulating substrate 102 (when present). The capillary structure may additionally or alternatively be provided by one or more channels or trenches in the electrically insulating substrate 102 (when present).

[0204] The carbon allotrope 101 may include pores. For example, the carbon allotrope 101 may be porous. The carbon allotrope 101 may be permeable, for example, permeable to liquids and / or gases.

[0205] The carbon allotrope 101 may be at least partially exposed. The carbon allotrope 101 may be a monolithic material.

[0206] The carbon allotrope 101 may have a heating surface. This heating surface may be partially or completely exposed. During use, aerosols may be emitted from this heating surface.

[0207] In some embodiments, the carbon allotrope 101 includes a capillary structure, and the electrically insulating substrate 102 also includes a capillary structure. In other embodiments, the carbon allotrope 101 includes a capillary structure, and the electrically insulating substrate 102 is non-porous (and does not include a capillary structure). It has been found that providing a non-porous substrate 102 reduces the carbon allotrope's exposure to a large amount of atomizable material during use (compared to embodiments with a porous substrate 102), thereby improving the efficiency of the aerosol component 100.

[0208] The aerosol generating component 100 includes a carbon allotrope 101 loaded on an electrically insulating substrate 102.

[0209] Carbon allotropes have been found to provide efficient aerosol-generating components. They provide a carbonaceous surface that distributes and atomizes atomizable materials during use. When heated to their atomization temperature, the carbonaceous surface possesses high surface free energy, resulting in high wettability. Thus, when heated to their atomization temperature, a thin layer of atomizable material can be uniformly distributed on the carbonaceous surface of the carbon allotropes and effectively atomized. Furthermore, carbon allotropes exhibit high power density, low thermal mass, and the ability to form thin, small-volume atomizable materials on a given surface area (as opposed to materials that cannot form thinly on their surface). This provides efficient energy transfer to the atomizable material during use.

[0210] Carbon allotropes can include carbon atoms configured to contain multiple carbon-carbon bonds located in the same plane. For example, carbon allotropes can include graphite. When the carbon allotrope includes graphite, the allotropy comprises stacked layers of multiple carbon atoms, with each carbon atom bonded to three adjacent carbon atoms in that layer, wherein each bond is located in the same plane to form a hexagonal lattice structure. Non-covalent bonding exists between the stacked layers.

[0211] Therefore, graphite comprises multiple stacked carbon layers, wherein the carbon layers are parallel to each other. There are two forms of graphite: α-graphite, in which the layers are stacked in an ABA pattern; and β-graphite, in which the layers are stacked in an ABC pattern.

[0212] Carbon allotropes can also include graphene. For example, a carbon allotrope can be graphene. In the case of a carbon allotrope being graphene, a single layer of carbon atoms (i.e., a layer as thick as carbon atoms) is arranged to form a hexagonal lattice structure.

[0213] It has been found that graphene provides a particularly effective aerosol-generating component. Advantageously, graphene's high thermal and electrical conductivity allows it to effectively dissipate heat, reduce temperature variations, and mitigate the severity of hot spots when hot spots (localized areas of elevated temperature that may occur during use when a portion of the heated aerosol-generating component dries out) form. Consequently, the aerosol-generating component can operate at high power levels with a reduced risk of hot spots damaging the component. Furthermore, graphene is elastic and therefore conforms to thermal expansion during use (e.g., thermal expansion of the electrically insulating substrate). Thus, the aerosol-generating component can resist degradation caused by the difference in thermal expansion coefficients between graphene and the electrically insulating substrate 102.

[0214] In the case of carbon allotropes including graphene, more than one layer of graphene can exist.

[0215] When more than one layer of graphene 101 is loaded on an electrically insulating substrate 102, at least two layers of graphene 101 can be non-parallel relative to each other. "Non-parallel" means that an imaginary plane passing through one graphene layer 101 (or the best-fit imaginary plane passing through a non-planar layer of one graphene layer 101) is not parallel to an imaginary plane passing through another graphene layer 101 (or the best-fit imaginary plane passing through another non-planar layer of another graphene layer 101). In use, the graphene layers 101 are electrically connected to form current paths. By providing non-parallel graphene layers, a porous graphene structure can be provided. The combination of graphene's porosity and low surface energy at typical atomization temperatures allows atomizable materials to be effectively distributed not only on the outermost surface of the graphene but also throughout the overall graphene structure. In effect, atomizable materials can be provided in close contact with the increased surface area of ​​the heated material provided by the graphene layers. This provides efficient and adequate atomization performance.

[0216] For example, at least three, at least four, at least five, at least six, at least eight, or at least ten of the graphene layers 101 are not parallel to each other.

[0217] When more than one layer of graphene 101 is loaded on the electrically insulating substrate 102, at least two layers of graphene 101 can be parallel to each other. For example, the carbon allotrope 101 can be a bilayer graphene.

[0218] For example Figures 4A to 4C As shown, some graphene layers 101 can directly contact the electrically insulating substrate 101, while some graphene layers 101 can be disposed on top of other graphene layers 101.

[0219] It will be understood that other carbon allotropes 101 have also been considered.

[0220] In some preferred embodiments, the carbon allotrope 101 comprises disordered graphite and / or amorphous carbon. In some preferred embodiments, the carbon allotrope 101 is selected from the group consisting of disordered graphite, amorphous carbon, or combinations thereof.

In such an embodiment, the Raman spectrum of carbon allotrope 101 can include a range from approximately 1310 cm⁻¹. -1 Approximately 1340 cm -1 The D-band peak is located within the Raman shift range. In this embodiment, the Raman spectrum of carbon allotrope 101 can be contained within approximately 2620 cm⁻¹. -1 Approximately 2680 cm -1 2D band peaks within the Raman shift range.

[0224] Intensity of D band peak I D The intensity of the G-band peak I G The ratio I D / I G The ratio I can range from approximately 0.8 to approximately 2. D / I G It can range from approximately 0.9 to approximately 1.9. Ratio I D / I G It can range from about 1 to about 1.8.

[0225] The G-band peak can have a value of approximately 30 cm⁻¹. -1 Approximately 100 cm -1 The full width at half maximum (FWHM) at the G-band peak can range from approximately 30 cm⁻¹. -1 Approximately 70 cm -1 FWHM.

[0226] 2D bands can follow either a Gaussian curve model or a Lorentz curve model.

[0227] Any of the above-mentioned features associated with Raman spectroscopy can be combined. For example, in some preferred embodiments, the Raman spectrum of carbon allotrope 101 includes G and D bands, wherein the G band peak is at approximately 1500 cm⁻¹. -1 Approximately 1650 cm -1 Within the Raman shift range, and the D-band peak is at approximately 1250 cm⁻¹. -1 Approximately 1400 cm -1 Within the Raman shift range, the intensity of the D band peak I D The intensity of the G-band peak IG The ratio I D / I G It ranges from about 0.8 to about 2. For example, in some preferred embodiments, the Raman spectrum of the carbon allotrope 101 includes G and D bands, wherein the G band peak is at about 1550 cm⁻¹. -1 Approximately 1590 cm -1 Within the Raman shift range, and the D-band peak is at approximately 1310 cm⁻¹. -1 Approximately 1340 cm -1 Within the Raman shift range, the intensity of the D band peak I D The intensity of the G-band peak I G The ratio I D / I G It is from about 1 to about 1.8.

[0228] For example, in some preferred embodiments, the carbon allotrope 101 is porous. For example, in some preferred embodiments, the carbon allotrope 101 is formed as a foam. The carbon allotrope 101 is conductive.

[0229] This paper describes the use of Raman microscopy to measure Raman spectra. A 638 nm laser wavelength was used for Raman microscopy analysis. A grating with 1800 grooves / mm was used. A 10.9 mW laser power was employed. A 5-second acquisition time was used. Twenty accumulations were used for Raman microscopy analysis. A 300 µm confocal pinhole was used for Raman microscopy. The results were obtained from approximately 1000 cm⁻¹. -1 up to approximately 3000 cm -1 Raman microspectroscopy analysis was performed within the specified wavelength range. In this study, Raman microspectroscopy was performed using a microscope objective with a 50x LWD (long working distance) and a 0.8 NA (numerical aperture). The Horiba Xplora Plus Raman microspectrometer was used. Raman microspectroscopy was performed at 21°C. The carbon allotrope 101 subjected to Raman microspectroscopy analysis in this study may have been unused. That is, the carbon allotrope 101 was not used to generate aerosols and / or was not heated to the typical nebulization temperature (after the fabrication of the carbon allotrope 101).

[0230] The inventors have used Raman microscopy to analyze various carbon allotropes 101 samples.

[0231] Each carbon allotrope 101 sample was prepared by laser irradiation of a polyimide (poly(4,4'-oxyphenylene-pyromellitictetrimimide), Kapton® HN, DuPont) substrate 102 (an electrically insulating substrate). Each polyimide substrate had a length of approximately 4.5 mm, a width of approximately 4.5 mm, and a thickness of approximately 125 µm, and was shaped into a rectangular prism. This involved irradiating an area of ​​approximately 4.5 mm by approximately 2 mm (i.e., approximately 9 mm) of polyimide substrate. 2 Each polyimide substrate of carbon allotrope 101 (and rectangular in shape) was formed using a laser beam. Raman microspectroscopy analysis was performed on each carbon allotrope 101 sample. Each carbon allotrope 101 sample was porous and conductive.

[0232] Unconstrained by theory, Raman spectroscopy is considered a non-destructive vibrational spectroscopy technique that uses a laser to excite bonds within a sample (e.g., carbon) and interprets the inelastic scattering of these bond vibrations as relative Raman shifts. Inelastic scattering from interactions with the sample produces these relative Raman shifts, thereby generating spectra that can be used to interpret the characteristics and / or identity of the sample. To characterize carbon allotropy 101 samples, studies can be conducted typically at approximately 1329 cm⁻¹. -1 The D band observed at approximately 1579 cm⁻¹ -1 The G-band observed at [location], and typically at approximately 2630 cm [location] -1 The peak position of the 2D band observed. The D band can be called the "disorder band" and is the sp. of carbon in the sample. 3 Indicator of hybridization. The G-band, also known as the "graphene band," is used to determine the sp(s) structure of carbon within a sample. 2 Hybridization. For example, the Raman spectrum of a pristine graphene sample will typically include a high-intensity, narrow G band and no D band. The Raman spectrum of a graphite sample typically includes both G and D bands, with the D band being less intense than the G band. D / I G The ratio can be determined by identifying the D band peak (I D The count of the intensity (au) of the G band peak (I) G The intensity count of the 2D bands can be used to determine the presence of carbon allotropes within a sample. The 2D bands can also be used to determine the morphology of allotropes by interpreting the area under the curve and the peak position. For example, crystalline graphite typically exhibits a sharp and narrow peak curve conforming to a Lorentz curve fitting model, while samples containing amorphous carbon typically exhibit a wider and flatter 2D band conforming to a Gaussian curve fitting model. The full width at half maximum (FWHM) of a peak can also be used to determine the crystallinity within a sample. The FWHM is measured by determining the width of the peak in question at half the total intensity of the sample.

[0233] Raman microspectroscopy involves measuring the Raman spectrum of each sample using a Horiba Xplora Plus Raman microspectrometer and the following parameters: A laser wavelength of 638 nm; A grating with 1800 grooves / mm; The data collection time is 5 seconds; 20 accumulations (20 spectra); 10.9 mW laser power; 300 µm confocal pinhole; and From approximately 1000 cm -1 Approximately 3000 cm -1 The wavelength range.

[0234] Raman microspectroscopy was performed at 21°C.

[0235] The carbon allotrope 101 sample, which underwent Raman microspectroscopy analysis, was not used.

[0236] The Raman spectra of each carbon allotrope 101 sample include the G band and the D band, with the G band peak at approximately 1550 cm⁻¹. -1 Approximately 1590 cm -1 Within the Raman shift range, and the D-band peak is at approximately 1310 cm⁻¹. -1 Approximately 1340 cm -1 Within the Raman shift range, the intensity of the D band peak I D The intensity of the G-band peak I G The ratio I D / I G The values ​​range from 1 to 1.8. The Raman spectra of each carbon allotrope 101 sample are from approximately 2620 cm⁻¹. -1 Approximately 2680 cm -1 The Raman shift range includes 2D band peaks. In the Raman spectra of each carbon allotrope 101 sample, the G band peak has a range from approximately 45 cm⁻¹. -1 Approximately 62 cm -1 The full width at half maximum (FWHM) of the peaks. In the Raman spectra of each carbon allotrope 101 sample, the 2D bands typically follow a Lorentz curve fitting model.

[0237] Raman spectra of each carbon allotrope 101 sample indicate that these samples include disordered graphite, amorphous carbon, or combinations thereof.

[0238] Figure 11 Raman spectra of one of the carbon allotropes 101 are shown. No sample was used. Figure 11 As shown, at approximately 1573 cm -1 A G-band peak was observed at approximately 1320 cm⁻¹.-1 A D-band peak was observed at approximately 2630 cm⁻¹. -1 A 2D band peak was observed at [location]. The intensity of the G band peak is I. G The intensity of the D band peak I D The ratio I G / I D It is approximately 1.6. The G-band peak has a length of approximately 62 cm⁻¹. -1 The FWHM 2D band follows a Lorentz curve fitting model.

[0239] The inventors have discovered that carbon allotropes 101 comprising disordered graphite, amorphous carbon, or combinations thereof are provided for particularly efficient aerosol generation components. Such carbon allotropes 101 are found to effectively dissipate heat, reduce temperature variations, and mitigate the severity of any hot spots. This carbon allotrope 101 exhibits low electrical resistance (and high electrical conductivity), making it particularly suitable for use in non-combustible aerosol supply systems. Such carbon allotropes 101 also promote efficient liquid distribution, e.g., throughout the surface and / or within the carbon allotrope.

[0240] Carbon allotrope 101 can have 100 Wm -1 k -1 Up to 5500 Wm -1 k -1 Thermal conductivity. Carbon allotrope 101 can have 100 W / m². -1 k -1 Up to 4000 Wm -1 k -1 Thermal conductivity.

Carbon allotrope 101 can have 900 Sm. -1 Up to 1300 Sm -1 The electrical conductivity.

[0242] Carbon allotropes 101 can exhibit nonlinear elasticity.

[0243] In embodiments including one or more graphene layers 101, the one or more layers can be provided in various forms. For example, the one or more graphene layers 101 can be formed into multiple three-dimensional structures. The three-dimensional graphene structures can be selected from cubes, cuboids, cones, cylinders (e.g., tubes), spheres, pyramids, and / or prisms. Those skilled in the art will be familiar with methods for producing three-dimensional graphene structures, including (but not limited to) arc discharge, laser ablation, high-pressure carbon monoxide dismutation, and chemical vapor deposition.

[0244] Carbon allotrope 101 can be formed into a foam. Carbon allotrope 101 can be formed into an open-cell foam. Carbon allotrope 101 may include a capillary structure. Open-cell foam may include a capillary structure.

[0245] exist Figures 4A to 4C An embodiment is shown in which one or more layers 101 may be provided.

[0246] like Figure 4AAs shown, one or more layers of graphene 101 can form an open-cell foam (referred to herein as "graphene foam"; see, for example, High-Resolution Laser-Induced Graphene. Flexible Electronics beyond the Visible Limit; Michael G. Stanford et al., ACS Applied Materials & Interfaces, 2020, Vol. 12, No. 9, pp. 10902-10907). The graphene foam can include capillary structures. The graphene foam can be formed by vapor deposition, such as chemical vapor deposition. The graphene foam includes a three-dimensional open-cell structure through which atomizable materials can pass, for example, through capillary action.

[0247] like Figure 4B As shown, a carbon allotrope (e.g., one or more graphene layers) 101 can be formed as multiple sheets. Gaps can exist between these sheets. The gaps between the sheets can provide a capillary structure. Atomizable materials can pass through the gaps, for example, via capillary action.

[0248] like Figure 4C As shown, carbon allotropes (e.g., one or more graphene layers) 101 can be formed into multiple nanotubes. Gaps may exist between the nanotubes. The interrelationships between the nanotubes and / or the tubular spaces within the nanotubes can provide a capillary structure. Atomizable materials can, for example, pass through the gaps and / or tubular spaces via capillary action.

[0249] Carbon allotropes (e.g., one or more graphene layers 101) can be sintered onto carbon allotropes 101. Sintering has been found to increase the mechanical strength and / or damage resistance of one or more graphene layers 101.

[0250] According to the present invention, a carbon allotrope is loaded onto an electrically insulating substrate. The thickness of the allotrope can vary depending on the properties of the electrically insulating substrate and the arrangement of the allotrope on it. The thickness of the allotrope is understood to refer to the extent of the carbon allotrope measured orthogonally between the loading surface of the electrically insulating substrate and the outer surface of the allotrope. In this regard, the outer surface refers to the surface of the carbon allotrope that does not have another layer loaded thereon when viewed orthogonally from the loading surface of the electrically insulating substrate. In the case where the carbon allotrope includes internal holes, these internal holes are effectively ignored in the thickness measurement. As an example, the first example carbon allotrope and the second example carbon allotrope will have the same thickness, differing only in the case that the first example allotrope has internal holes and the second example allotrope is non-porous. Therefore, the thickness of the carbon allotrope can refer to the thickness of a single layer or multiple layers. Those skilled in the art will know suitable methods for measuring the thickness of carbon allotropes, such as electron microscopy.

[0251] For example, when the allotrope exists as a single layer of graphene, its thickness will have a natural lower limit corresponding to the thickness of a single layer of graphene, which can be 0.345 nm. However, when it exists as a multilayer graphene, the thickness will be greater than 0.345 nm.

In some embodiments, the carbon allotrope 101 has a thickness from 5 nm to 10 nm.

[0258] In some embodiments, the carbon allotrope 101 is loaded on at least 50% of the surface 102a of the electrically insulating substrate 102. In some embodiments, the carbon allotrope 101 is loaded on at least 70% of the surface 102a of the electrically insulating substrate 102. In some embodiments, the carbon allotrope 101 is loaded on at least 90% of the surface 102a of the electrically insulating substrate 102. In some embodiments, the carbon allotrope 101 is loaded on substantially 100% of the surface 102a of the electrically insulating substrate 102.

[0259] The surface 102a of the carbon allotrope 101 can provide at least 30% of the outer surface area of ​​the electrically insulating substrate 102. The surface 102a of the carbon allotrope 101 can provide at least 40% of the outer surface area of ​​the electrically insulating substrate 102. The surface 102a of the carbon allotrope 101 can provide at least 45% of the outer surface area of ​​the electrically insulating substrate 102.

[0260] In some embodiments, the surface 102a on which the carbon allotrope 101 is loaded is curved.

[0261] In some embodiments, the surface 102a of the carbon allotrope 101 is substantially planar.

[0262] The surface 102a on which the carbon allotrope 101 is loaded can be a main surface. A "main surface" is the surface with the largest (or most commonly largest) area relative to the other surfaces of the electrically insulating substrate 102. For example, the main surface of a rectangular prism-shaped electrically insulating substrate 102 having a length of 15 cm, a width of 2 cm, and a height of 1 cm is a surface defined by its length and width (which exist in both cases). Figure 3 , 5A In each of 6A, 7A, 7B, 8A and 8B, one or more graphene layers 101 are shown loaded on the main surface of the electrically insulating substrate 102.

[0263] The aerosol generating component 100 may include one or more electrodes 103 configured to be in electrical contact with the carbon allotrope 101. The one or more electrodes 103 may be configured to be in direct electrical contact with the carbon allotrope 101. The one or more electrodes 103 are configured to form an electrical connection with a power source, such that electrical power can be delivered to the aerosol generating component 100 (e.g., the carbon allotrope 101).

[0264] The aerosol generating component 100 may include two electrodes 103, each electrode 103 being configured to be in electrical contact with the carbon allotrope 101. In embodiments with two electrodes 103, one of the electrodes may be positioned toward or at an end of the aerosol generating component 100, and the other electrode 103 may be positioned toward or at an opposite end of the aerosol generating component 100.

[0265] One or more electrodes 103 are made of any suitable conductive material. For example, one or more electrodes 103 may be selected from copper, silver or gold.

[0266] The one or more electrodes 103 can be sintered onto the carbon allotrope 101. The sintering can be performed at a temperature ranging from 100°C to 300°C, for example from 120°C to 200°C. The sintering can be carried out for a duration of 5 seconds to 5 minutes, for example from 10 seconds to 3 minutes. Those skilled in the art will understand that the sintering conditions can be varied.

[0267] In this disclosure, the carbon allotrope 101 is configured such that at a temperature of 150°C, the contact angle between the glycerol droplet and the surface of the carbon allotrope 101 is no greater than 20 degrees.

[0268] Contact angle can be measured using the Wilhelmy plate method, EM, analog, or goniometer. Contact angle can also be measured optically, for example, by photogrammetry. This method of measuring contact angle is familiar to those skilled in the art.

[0269] What will be understood is that the "contact angle" is the angle at which a liquid-gas interface encounters a solid surface, and this contact angle is quantified by Young's equation regarding the wettability of a liquid on a solid surface:

[0270] γ S It is the surface tension of a solid, γ L It is the surface tension of the liquid, and γ SL It is the boundary tension between the solid and the liquid (solid-liquid interface energy), and θ is the contact angle.

[0271] It has been found that when the carbon allotrope 101 is constructed in this way, during use, the atomizable material can form a thin layer uniformly distributed on the surface of the carbon allotrope 101, and the atomizable material can be effectively distributed throughout the overall structure of the carbon allotrope 101. Furthermore, the atomizable material can be rapidly distributed on the carbon allotrope 101, and the evaporated atomizable material can be quickly replenished. In addition, the aerosol generating component 100 has a reduced tendency to "dry out," that is, the phenomenon where the aerosol generating component 100 or a portion thereof inadvertently dries out because the rate of replenishment of atomizable material is less than the rate of evaporation of the atomizable material.

[0272] The temperature at which the contact angle is measured can refer to the temperature measured at the surface of the carbon allotrope on which glycerol droplets are provided.

[0273] At 150°C, the contact angle between a glycerol droplet and the surface of the carbon allotrope 101 may not exceed 18 degrees. At 150°C, the contact angle between a glycerol droplet and the surface of the carbon allotrope 101 may not exceed 16 degrees.

[0277] The one or more dopants may include a p-type dopant. The p-type dopant may be selected from the group consisting of boron and sulfur.

[0278] It has been found that the presence of such dopants promotes a reduction in contact angle and thus improves wettability.

Such an aspect ratio has been found to provide desired heating performance in use. In particular, this aspect ratio has been found to exhibit the desired atomization rate and energy efficiency.

[0283] The heating surface can be considered as part of the carbon allotrope 101 that reaches the temperature required to atomize the atomizable material in use.

[0284] For example, the heating surface of the carbon allotrope 101 can have an aspect ratio of 5:1 to 40:1. The heating surface of the carbon allotrope 101 can have an aspect ratio of 5:1 to 35:1. The heating surface of the carbon allotrope 101 can have an aspect ratio of 5:1 to 30:1. The heating surface of the carbon allotrope 101 can have an aspect ratio of 5:1 to 25:1.

In this specific embodiment, the aerosol generating component 100 passes through an aerosol generating material transport component, which is a reservoir of atomizable material (such as...). Figure 6A and 6B (As shown). The aerosol generating component 100 contacts the surface of the atomizable material in the reservoir. The energy density is indicated by the energy provided per mm² by the aerosol generating component 100. 2 The amount of energy. Efficiency ( Figure 10A The blue cross in the figure corresponds to the amount of energy required to volatilize 1 mg of atomizable material from 100 mg of aerosol-generating component. In this case, the atomizable material is an aqueous solution of glycerol (50 wt.% glycerol).

It has been found that, despite the presence of at least one pore, heat is uniformly distributed on the aerosol generating component 100 during use. This uniform heat distribution advantageously provides stable atomization and a reduced tendency to form "hot spots."

Specifically, at least one atomizable material supply section 100b effectively delivers atomizable material to the heating section 100a. Furthermore, it has been found that when the aerosol generating component 100 is energized, heat energy does not significantly diffuse to the at least one atomizable material supply section 100b. This is... Figure 8B As shown in the figure, Figure 8B It is in use Figure 8A A thermal diagram of the aerosol generating component 100 is provided, wherein the aerosol generating component 100 is energized to the atomization temperature using a power source. Furthermore, at least one atomizable material supply section 100b is used to deliver atomizable material to the heating section 100a, reducing or preventing the formation of vapor between the outer surface of the heating section and the atomizable material. This can occur in cases where the atomizable material is directly delivered to the outer surface of the heating section, potentially leading to accidental ejection of the atomizable material (e.g., "splashing" or "sputtering").

[0302] like Figure 8A and 8B As shown, the heating portion 100a can be elongated. For example, the heating portion 100a can be formed as a plate, strip, or rod. The heating portion 100a can be linear. Alternatively, the heating portion 100a can be non-linear.

In some embodiments, the heating portion 100a has a width from 1 mm to 3 mm.

[0306] The aerosol generating component 100 may include multiple (e.g., at least two, three, four, five, or six) atomizable material supply sections 100b, each extending from the heating section 100a. Figure 8A and 8B As shown, the atomizable material supply portion 100b, or each atomizable material supply portion 100b, can extend from the side of the heating portion 100a. Figure 8A and 8B As shown, the atomizable material supply portion 100b, or each atomizable material supply portion 100b, can extend laterally into the longitudinal range of the heating portion 100a. The atomizable material supply portion 100b, or each atomizable material supply portion 100b, can extend laterally from the heating portion 100a.

[0307] The aerosol generating component 100 can be substantially planar. In this way, the heating part 100a and at least one atomizable material supply part 100b can be arranged in the same plane.

[0308] The atomizable material supply portion 100b, or each atomizable material supply portion 100b, may be elongated 100a. For example, the atomizable material supply portion 100b, or each atomizable material supply portion 100b, may be formed as a plate, strip, or rod. The atomizable material supply portion 100b, or each atomizable material supply portion 100b, may be linear.

[0309] The atomizable material supply portion 100b, or each atomizable material supply portion 100b, may have an aspect ratio of 1:1 to 5:1. The width of the atomizable material supply portion 100b, or each atomizable material supply portion 100b, may be 1 to 3 mm. The length of the atomizable material supply portion 100b, or each atomizable material supply portion 100b, may be 1 to 15 mm.

[0310] The atomizing material supply section 100b, or each atomizing material supply section 100b, can be tapered. For example... Figure 8A and 8B As shown, the atomizable material supply section 100b or each atomizable material supply section 100b can be tapered away from the elongated heating section 100a.

[0311] At least one atomizable material supply portion 100b may be porous. At least one atomizable material supply portion 100b may include capillary material. At least one atomizable material feeding portion 100b may have any characteristics of an electrically insulating substrate as defined herein.

The atomizable material supply portion 100b, or each atomizable material supply portion 100b, may extend obliquely or orthogonally from the longitudinal extending direction of the heating portion 100a.

[0313] The heating section 100a includes a carbon allotrope 101 disposed on an electrically insulating substrate 102. The atomizable material supply section 100b, or each atomizable material supply section 100b, includes an electrically insulating substrate 102.

[0314] In some implementations (e.g. in) Figure 7A , 7B In 8A and 8B), at least one atomizable material supply portion 100b includes a carbon allotrope 101 and an electrically insulating substrate 102. In some embodiments, at least one atomizable material supply portion 100b includes an electrically insulating substrate 102, for example, a portion of the electrically insulating substrate 102 on which the carbon allotrope is not loaded (according to...). Figure 7A , 7B 8A and 8B).

[0315] In some embodiments, the heating portion 100a and the substrate 102 are integrally formed.

[0316] In one aspect of this disclosure, an aerosol generation assembly is provided, including an aerosol generation component 100 of any aspect of this disclosure and an aerosol generation material transport component 200 for supplying aerosol generation material to the aerosol generation component 100.

[0317] Figure 5A Examples of aerosol generation components are shown up to 6C.

[0318] The aerosol generating material transport component 200 can be used to passively supply aerosol generating material to the aerosol generating component 100. "Passively supplying" means that the aerosol generating material transport component 200 does not require electricity to deliver the aerosol generating material to the aerosol generating component 100. For example, the aerosol generating material transport component 200 may include a porous structure. For example, the aerosol generating material transport component 200 may include a capillary structure. Capillary structures have been found to be particularly effective for transferring atomizable materials to the aerosol generating component 101.

[0319] like Figures 5A to 5C As shown, the aerosol generating material transport component 200 may include at least one capillary channel 201 having an outlet 202. The outlet 202 may be configured adjacent to the aerosol generating component 100 (e.g., one or more layers of graphene 101 and / or substrate 102) such that atomizable material exiting the outlet 202 directly contacts the aerosol generating component. Figures 5A to 5C In the orientation shown, outlet 202 is arranged to supply aerosol generating material from above or beside aerosol generating component 100 relative to gravity.

[0320] like Figures 5A to 5C As shown, the capillary channel 201 (or each) can be formed by a first layer (e.g., a capillary layer) 203 and a second layer (e.g., a base layer) 204. Figures 5A to 5B In this configuration, the first layer 203 and the second layer 204 are spaced apart by approximately 0.1 mm to 0.5 mm (although the spacing may vary). The outlet 202 of the capillary channel 201 may be located at the end of the first layer 203 and the second layer 204, adjacent to the aerosol generating component 100 (e.g., carbon allotrope 101 and / or substrate 102). At least one capillary channel 201 may be provided in various forms. The capillary channel 101, or each capillary channel, may include grooves or conduits. In some embodiments, the aerosol generating component may include multiple capillary channels (each capillary channel may independently include any of the features of a capillary channel described herein).

[0321] The first layer 203 can be formed of any one of plastic, glass, paper, and ceramic. The first layer 203 can be non-porous. The second layer 204 can be formed of any one of plastic, glass, paper, and ceramic. The second layer 204 can be non-porous. Figure 5A and 5B In the middle, each of the first layer 203 and the second layer 204 is made of glass.

[0322] like Figure 6A and 6B As shown, the aerosol generating material transport component 200 may include a reservoir 210. For example, the aerosol generating component 100 may extend through the reservoir 210. Figure 6A and Figure 6B In the illustrated orientation, the reservoir 210 is configured to supply aerosol-generating material from below the aerosol-generating component 100 to the aerosol-generating component 100 relative to gravity. The reservoir 210 may be configured to include a quantity of atomizable material such that the atomizable material directly contacts the aerosol-generating component 100 (e.g., one or more layers of graphene 101), for example, its outer surface, particularly the surface provided by one or more layers of graphene 101.

[0323] The aerosol generating assembly may include a moving mechanism (not shown) for moving (e.g., raising or lowering) the aerosol generating component 100 to maintain direct contact between the aerosol generating component 100 and any atomizable material in the reservoir 210. The moving mechanism may be automatically controlled by a controller.

[0324] In one aspect of the invention, an article of manufacture is provided for use as part of a non-combustible aerosol supply system, the article of manufacture comprising an aerosol generating component 100 or an aerosol generating assembly of any aspect of the invention.

[0325] In one aspect of this disclosure, an article of manufacture is provided as part of a non-combustible aerosol supply system, the article of manufacture comprising: an aerosol generating component 100 including a heating portion 100a according to any aspect of this disclosure and at least one atomizable material supply portion 100b; and at least one reservoir for the atomizable material, wherein the atomizable material supply portion 100b or each atomizable material supply portion 100b is configured to be in fluid communication with at least one of the at least one reservoir.

[0326] The atomizable material supply section 100b or each atomizable material supply section 100b may extend to or enter at least one or more reservoirs. In this way, the atomizable material supply section 100b or each atomizable material supply section 100b may directly deliver the atomizable material from the reservoir to the heating section 100a.

[0327] The heating element 100a may be biased toward at least one reservoir. For example, the article may include an aerosol generation chamber. An aerosol generation component may be arranged at least partially within the aerosol generation chamber. For example, the heating element 100a may be arranged within the aerosol generation chamber. The reservoir may radially surround the aerosol generation chamber. In this way, the reservoir may form a ring around the aerosol generation chamber (the ring may be partial or complete).

[0328] At least one airflow path may extend through the article. The article may include at least one inlet and at least one outlet. At least one airflow path may extend from at least one inlet to at least one outlet. The airflow path may include an aerosol generation chamber.

[0329] The article can be oriented such that, during use, air flows along the aerosol generating component (e.g., along the surface of the aerosol generating component 100, e.g., the heating portion 100a) in a surface direction. For example, during use, air may enter the article through at least one inlet, flow through an airflow path via an aerosol generating chamber disposed therein in the aerosol generating component 100 (e.g., the heating portion 100a), and exit the article through at least one outlet.

[0330] In one aspect of this disclosure, a non-combustible aerosol supply system is provided, comprising: an aerosol generating component 100 of any aspect of this disclosure, or an aerosol generating assembly of any aspect of this disclosure, or an article of manufacture of any aspect of this disclosure; and one or more of a power supply and a controller.

[0331] The power source is used to supply power to the aerosol generating components (e.g., carbon allotropes 101).

[0332] The controller can be configured to electrically communicate with the aerosol generating component 100 (e.g., carbon allotrope 101), wherein the controller is configured to control the power supply to the aerosol generating component 100 (e.g., carbon allotrope 101) via a power source. The controller can be configured to supply atomizable material to the aerosol generating component 100. This supply can be active. Active supply can be achieved via an active supply device, such as a pump.

[0333] The amount of power supplied to the aerosol generating unit 100 can be based on the amount of atomizable material supplied to the aerosol generating unit 100. Thus, the system can be configured such that when no atomizable material is supplied to the aerosol generating unit 100, the power is set to zero or a reference value, and when atomizable material is supplied to the aerosol generating unit, the power is set to a higher value. Such a device has been found to exhibit improved energy efficiency while maintaining the desired heating performance.

[0334] Therefore, when no atomizable material is supplied to the aerosol generating unit 100, the controller can be configured not to supply power to the aerosol generating unit. When no atomizable material is supplied to the aerosol generating unit 100, the controller can be configured such that a reference power (greater than zero) is supplied to the aerosol generating unit. The reference power is less than the power supplied to the aerosol generating unit 100 when aerosol generating material is supplied. The use of the reference power advantageously reduces the time to reach the atomization temperature while limiting power consumption during non-use processes.

[0335] In one aspect of this disclosure, a method for forming an aerosol generating component 100 in any aspect of this disclosure is provided.

[0336] The method may include the step of forming a carbon allotrope 101 on an electrically insulating substrate 102. The carbon allotrope 101 may be as defined herein.

[0337] The carbon allotrope 101 can be formed on the electrically insulating substrate 102 by printing.

[0338] The carbon allotrope 101 can be formed on the electrically insulating substrate 102 by laser irradiation. In embodiments where the carbon allotrope 101 is formed as foam, the foam can be formed on the electrically insulating substrate 102 by laser irradiation. Laser irradiation can include irradiating the electrically insulating substrate 102 with a laser beam, wherein the electrically insulating substrate 102 is a carbon-containing material. In embodiments involving laser irradiation, the electrically insulating substrate 102 can be formed of polyimide (PI). Laser irradiation can be performed in an inert environment.

[0339] Therefore, in some embodiments, the method of forming the aerosol generating component 100 includes forming a carbon allotrope 101 on an electrically insulating substrate 102 by laser irradiation, the laser irradiation including irradiating the electrically insulating substrate 102 with a laser beam, wherein the electrically insulating substrate 102 is a carbon-containing material (optionally formed of polyimide (PI)) and the carbon allotrope 101 is formed as a foam.

[0340] Carbon allotropes 101 can be formed on electrically insulating substrates 102 by laser-induced deposition.

[0341] When the carbon allotrope 101 is or includes one or more graphene layers, this can be achieved by laser-induced graphene (LIG) formation on an electrically insulating substrate 102. Laser-induced graphene formation involves irradiating the electrically insulating substrate 102 with a laser beam, wherein the electrically insulating substrate is a carbon-containing material. LIG can be used to form graphene foam on the electrically insulating substrate.

[0342] Carbon allotropes 101 can be formed on an electrically insulating substrate 102 by chemical vapor deposition (CVD). CVD involves flowing a carbon-containing gas (e.g., methane) (and optionally hydrogen) through the electrically insulating substrate 102. This CVD can be performed at sub-atmospheric pressure and is also known as low-pressure CVD. CVD can be used to form graphene foam on the electrically insulating substrate.

[0343] The method may include the step of forming one or more electrodes 103 in contact with the carbon allotrope 101.

[0344] It has been found that by forming two or more electrodes 103 in contact (i.e., direct contact) with the carbon allotrope 101, relative to an aerosol generating component (i.e., an auxiliary component; typically, silver contacts) where the electrodes are connected to the heater via electrical contacts, aerosol generating components 100 of a specific size can be configured to generate aerosols (e.g., a larger surface area of ​​the aerosol generating component 100 can be exposed to the atomizable material), thereby improving atomization performance, when such electrical contact is not required. The direct connection between one or more electrodes 103 and the carbon allotrope 101 relative to the aerosol generating component where the electrodes are connected to the heater via electrical contacts also provides improved low-loss electrical and / or mechanical connections therebetween.

[0345] Forming one or more electrodes 103 in contact with the carbon allotrope 101 may include a sintering step. For example, forming at least one electrode 103 in contact with the carbon allotrope 101 may include sintering the at least one electrode to the carbon allotrope 101.

[0346] Electrode 103 may be selected from copper, silver, and gold. The electrode, or each electrode 103, is made by sintering, for example, sintered copper, sintered silver, or sintered gold. Copper (e.g., sintered copper) has been found to be particularly effective in forming direct, low-loss electrical connections.

[0347] The method may include forming one or more grooves and / or one or more holes in the electrically insulating substrate before placing the carbon allotrope 101 on the substrate. One or more holes penetrate the substrate 102 (i.e., serve as through-holes). The grooves and holes facilitate the distribution and passage of atomizable material across and through the aerosol generating component 100, and improve heating efficiency.

[0348] In some embodiments, the substrate 102 is glass, such as borosilicate glass (e.g., "Willow Glass") or quartz glass (fused silica).

[0349] For example, Figure 9A carbon allotrope 102 formed on a borosilicate glass substrate 102 is shown, along with two copper electrodes 103 in contact with the carbon allotrope 102.

[0351] In one aspect of this disclosure, a method of operating a non-combustible aerosol supply system according to any aspect of this disclosure is provided, the method comprising the step of supplying power to an aerosol generating component 100.

[0352] The method may include a drive controller to control (e.g., activate or deactivate) the supply of atomizable material to the aerosol generating component 100.

[0353] The method may include a drive controller to control (e.g., start or stop) the power supply to the aerosol generating component 100.

[0354] The method may include supplying power to the aerosol generating component 100 based on the amount of atomizable material supplied to the aerosol generating component 100. The method may include supplying a reference power (greater than zero) to the aerosol generating component 100 when no atomizable material is supplied to the aerosol generating component 100. The method may also include supplying an amount of power greater than the reference power to the aerosol generating component 100 when atomizable material is supplied to the aerosol generating component 100.
