Description

Technical Field

[0001] This disclosure generally relates to the field of aerosol generating apparatus, systems, and devices for generating aerosols. This disclosure also relates to an aerosol generating matrix and an aerosol generating article for generating aerosols. Background Technology

[0002] Typically, aerosol generating devices are designed as handheld devices that can be used by a user to consume or experience aerosols generated by heating an aerosol generating matrix or aerosol generating article during one or more uses.

[0003] Exemplary aerosol generating matrix may comprise a solid matrix material, such as tobacco material or tobacco cast leaf (“TCL”) material. The matrix material may, for example, be assembled with other elements or components to form a substantially rod-shaped aerosol generating article. Such a rod or aerosol generating article may be configured in shape and size to be at least partially inserted into an aerosol generating apparatus, which may include, for example, a heating element for heating the aerosol generating article and / or the aerosol generating matrix. Alternatively or additionally, the aerosol generating matrix may comprise one or more liquids and / or solids, which may be supplied to the aerosol generating apparatus, for example, in the form of a cylinder or container. A corresponding exemplary aerosol generating article may, for example, comprise a cylinder containing or potentially filled with a liquid and / or solid matrix that may evaporate during aerosol consumption based on heating the matrix. Typically, such a cylinder or container may be coupled to, attached to, or at least partially inserted into an aerosol generating apparatus. Alternatively, the cylinder may be fixedly mounted to the aerosol generating apparatus and refilled by inserting liquid and / or solids into the cylinder.

[0004] To generate an aerosol during use or consumption, heat can be supplied by a heating element or heat source to heat at least a portion or part of the aerosol generating matrix. The heating element or heat source can be arranged within the handheld device or the handheld portion of the aerosol generating apparatus. Alternatively or additionally, at least a portion or all of the heating element or heat source can be fixedly associated with or arranged within the aerosol generating article, for example, in the form of a rod or cylinder, which can be attached to and / or powered by the handheld device or the handheld portion of the aerosol generating apparatus.

[0005] Various forms and designs of heating elements, as well as various heating technologies, are currently used in the field of aerosol generation devices and systems. See also the references below. Figure 1As described, conventional heating elements may include resistance heating blades arranged in the heating chamber of an aerosol generating apparatus. The resistance heating element can contact the aerosol generating matrix or article, for example, by inserting it into the aerosol generating apparatus, and can generate aerosols by resistively heating the heating blades. The heating blades may undergo mechanical deformation due to the insertion or removal process, which can adversely affect the overall heating of the aerosol generating matrix. For example, mechanical deformation or wear of the heating blades can lead to heterogeneous heating of the matrix, particularly during multiple uses or replacements of the aerosol generating article. Furthermore, heat transfer from the heating blades to different portions of the matrix can depend on the orientation of the corresponding portion of the matrix relative to the heating blades and the distance between the corresponding portion of the matrix and the heating blades. This can also produce a heterogeneously heated matrix. In another variation, for example, as referenced below… Figure 2 The description describes how a receptor or receptor material can be arranged at the center of an aerosol generating article or matrix, for example, in the form of a planar metal strip of ferromagnetic material at least partially surrounded by an aerosol generating matrix. Moreover, these types of aerosol generating articles are typically inserted into an aerosol generating apparatus for aerosol consumption. Eddy currents (also known as Foucault currents) can be generated in the receptor by applying an alternating magnetic field, for example, using a coil arranged in the aerosol generating apparatus, thereby heating the receptor and the aerosol generating matrix nearby. Again, in this example, uniform or homogeneous heating of the matrix may be difficult to achieve due to the different orientations and distances of different portions of the matrix relative to the receptor. In yet another example, a heating coil can be arranged in a cylindrical aerosol generating article to heat the liquid matrix contained therein. Again, heat can be supplied locally to the matrix, resulting in heterogeneous overall heating of the matrix. This heterogeneous heating of the matrix can lead to potentially different experiences for the user between various usage processes, such as in terms of the amount, flavor, or taste of the generated aerosol. Furthermore, certain portions or parts of the aerosol-generating matrix may be overheated, potentially generating or releasing unwanted substances, while other portions or parts of the matrix may not be sufficiently heated to generate aerosols, potentially leading to a waste of matrix material.

[0006] Therefore, it may be necessary to provide improved aerosol generating devices, which, for example, at least mitigate or overcome some or all of the aforementioned disadvantages of conventional aerosol generating devices and systems. Summary of the Invention

[0007] This problem is addressed by the subject matter of the independent claims. Optional features are provided by the dependent claims and the following description.

[0008] According to a first aspect, an aerosol generating apparatus is provided, the aerosol generating apparatus being configured to generate an aerosol by or based on heating at least a portion of an aerosol generating matrix. The aerosol generating apparatus includes at least one annular resonator configured to heat at least a portion of the aerosol generating matrix to generate an aerosol.

[0009] By providing an annular gap resonator, hereinafter also referred to as "LGR", at least one portion of the aerosol generation matrix can be homogeneously heated to a temperature sufficient to generate aerosols, such as a predetermined or desired temperature. Alternatively or additionally, by using an LGR to heat at least one portion of the aerosol generation matrix, a mechanically robust and compact aerosol generation device can be provided. Using an LGR to heat the aerosol generation matrix may be more advantageous in terms of energy efficiency, for example, allowing heating at least one portion of the matrix with reduced or minimal energy consumption.

[0010] In the context of this disclosure, a ring gap resonator can refer to an electromagnetic resonator that operates, for example, in the radio and / or microwave frequency range, such as kHz to THz frequencies. Typically, an LGR may include at least one ring or ring portion and at least one gap or gap portion formed within the conductive body of the LGR, for example integrally formed with the body of the LGR.

[0011] In terms of physical or electrical characteristics, an LGR can be modeled as a lumped-element circuit or a so-called LCR circuit (or LRC circuit). For example, a typical LGR can be considered equivalent to an inductor with an effective inductance L, an effective capacitance C, and an effective resistance R connected in series, plus an optional generator. Therefore, the alternating current induced or operating in an LGR can depend on the frequency of the current and can reach its maximum at the resonant frequency of the LGR or its corresponding LCR circuit. As used herein, the “resonant frequency” of an LGR can refer to or represent the frequency of the alternating current operating in the LGR at which the current reaches its maximum value and / or at which the impedance of the LGR (or its corresponding LCR circuit) reaches its minimum value.

[0012] As will be discussed in more detail below, various types, forms, and designs of toroidal gap resonators can be advantageous in aerosol generation apparatuses and systems according to this disclosure. For example, the toroidal gap resonator can be at least one of a cylindrical toroidal gap resonator, a tubular toroidal gap resonator, a ring-shaped toroidal gap resonator, a spiral toroidal gap resonator, a multi-ring toroidal gap resonator, and a multi-gap toroidal gap resonator. All these different types, forms, and designs of LGRs are explicitly envisioned for use in aerosol generation apparatuses and systems according to this disclosure.

[0013] An LGR can be configured, for example, to generate or produce alternating electromagnetic fields. Specifically, the LGR can be configured to generate, for example, one or more regions of an alternating electric field within at least one gap or gap portion of the LGR, and one or more regions of an alternating magnetic field within, for example, at least one ring or ring portion of the LGR. Preferably, the LGR can be configured to generate alternating electric and alternating magnetic fields that can be isolated from or separated from each other, and both can be substantially or substantially homogeneous. As used herein, an electric or magnetic field can be considered “homogeneous” or “uniform” if the intensity of the respective field is constant within a maximum relative deviation of about 30%, 25%, 20%, 15%, 10%, or 5%. Subsequently, one or both of the alternating electric and magnetic fields generated by the LGR can be advantageously used to uniformly and homogeneously heat the aerosol-generating matrix to generate aerosols. As used herein, “uniform heating” or “homogeneous heating” may mean that the amount or quantity of heat or thermal energy transferred to or received by the aerosol generating matrix per volume is substantially constant or constant within a certain relative deviation, such as within a maximum relative deviation of about 30%, 25%, 20%, 15%, 10%, or 5%.

[0014] The annular gap resonator can be configured to heat at least one portion of the aerosol generation matrix, for example, based on or using induction heating, or microwave heating, for example, based on or using an alternating electric field generated by the annular gap resonator. It should be noted that the LGR can be configured to heat one or more portions of the matrix or multiple matrices. For example, the LGR can be configured to heat at least one portion of the aerosol generation matrix based on induction heating, and optionally to heat at least another portion of the aerosol generation matrix based on microwave heating, or vice versa. Wherein, at least one portion and at least another portion of the matrix can be physically separate portions of the matrix, or can refer to at least some identical or overlapping portions of the matrix.

[0015] At least one portion of a ring-gap resonator may form a ring of the ring-gap resonator or may be formed as a ring-gap resonator, the ring being configured to receive at least one portion of the aerosol-generating matrix, wherein the ring-gap resonator may be configured to heat at least one portion of the aerosol-generating matrix based on generating an alternating magnetic field within the ring of the ring-gap resonator. As used herein, "ring" of an LGR may refer to or denote a ring portion of an LGR defining the core or aperture of the LGR, wherein the LGR generates (e.g., substantially uniformly) an alternating magnetic field. An LGR or at least one ring or ring portion thereof may be configured, for example, to at least partially surround or enclose at least one portion of the aerosol-generating matrix along its periphery. By receiving at least one portion of the matrix with a ring or ring portion of the LGR, the matrix or at least one portion thereof can be heated efficiently, uniformly, and homogeneously, particularly with reduced or minimal mechanical wear and energy consumption.

[0016] An annular gap resonator (LGR) can be configured to heat at least a portion of the aerosol-generating matrix based on eddy currents induced in a sensor or sensor material disposed within and / or deposited on the aerosol-generating matrix. Specifically, the alternating magnetic field generated by the LGR can interact with the sensor or sensor material, inducing eddy currents therein according to Faraday's law. Due to the resistance of the sensor or sensor material, the electrical energy associated with the eddy currents can be at least partially converted into heat energy, or thermal energy, based on Joule's law, which in turn heats the matrix to generate aerosols. Alternatively or additionally, the LGR can be configured to heat the matrix at least partially based on hysteresis losses, which can be caused by internal friction between magnetic molecules in the sensor and the alternating magnetic field generated by the LGR. Other losses, including domain wall resonances, electron spin resonances, and residual losses, may potentially contribute to the overall heating of the matrix or at least a portion thereof.

[0017] As will be discussed in more detail below, various types of receptors or receptor materials may be disposed within and / or deposited on the aerosol-generating matrix, and this disclosure contemplates the optional use of all such types of receptors or receptor materials. Typically, receptors or receptor materials may comprise conductive and / or resistive materials, such as ferromagnetic materials, metals, or steel. For example, a metal strip or planar metal strip disposed within the matrix and / or within an aerosol-generating article comprising the matrix may serve as a receptor. Alternatively or additionally, the receptor or receptor material may be spatially homogeneously distributed within the matrix or at least a portion thereof. This may mean that the density of the receptor or receptor material is substantially constant or constant within a certain relative deviation, for example, within a maximum relative deviation of about 30%, 25%, 20%, 15%, 10%, or 5%.

[0018] For example, the receptor or receptor material may comprise small and / or small-sized ferromagnetic material particles disposed within or coated on the aerosol-generating matrix. Alternatively or additionally, the receptor material may comprise a fluid or liquid and / or ionic liquid having magnetic properties, which may be added to or coated onto the matrix, for example, coated onto a tobacco casting leaf composed of the matrix or added to a liquid matrix. A homogeneous distribution of the receptor or receptor material within the matrix may further support or produce substantially uniform heating of the matrix (also referred to as "homogeneous heating").

[0019] Furthermore, at least two portions of the annular gap resonator can be arranged opposite to each other and spaced apart, such that the at least two portions form a gap in the annular gap resonator, the gap being configured to receive at least one portion and / or at least another portion of the aerosol generating matrix. The annular gap resonator can be configured to heat at least one portion and / or at least another portion of the aerosol generating matrix based on generating an alternating electric field within the gap of the annular gap resonator. The at least two portions of the LGR can be separated by a distance, which can be constant over the length of the gap or can vary over the length of the gap. As used herein, "gap" in LGR can refer to or denote a gap portion of the LGR enclosed by at least two opposing and spaced portions of the LGR, in which the LGR generates (e.g., substantially uniform) an alternating electric field. Thus, at least two opposing portions can define a gap or gap portion on at least two opposing sides. The LGR or at least its gap can be configured, for example, to at least partially surround or enclose at least one portion of the aerosol generating matrix and / or at least another portion of the matrix on its two opposing sides. By receiving at least one portion of the substrate and / or at least another portion of the substrate within the gap or gap portion of the LGR, the substrate can be heated efficiently, uniformly, and homogeneously, particularly with reduced or minimal mechanical wear and energy consumption.

[0020] The annular gap resonator can be at least one of a cylindrical annular gap resonator, a tubular annular gap resonator, a ring annular gap resonator, a spiral annular gap resonator, a multi-ring annular gap resonator, and a multi-gap annular gap resonator. One or more of these types of LGRs can be included in an aerosol generation apparatus to heat a matrix and generate an aerosol. Therefore, the aerosol generation apparatus can also include multiple LGRs, such as multiple LGRs of the same type or different types.

[0021] A cylindrical or tubular annular gap resonator may include a tubular body forming a ring of the LGR and a slit or cut extending along at least a portion of the length of the tubular body, wherein the slit may form a gap or gap portion of the LGR. The slit or cut may extend parallel to or transverse to the longitudinal axis of the tubular body of the LGR. In other words, the tubular or cylindrical LGR may include a conductive tubular body or tube longitudinally cut by the slit or gap. The tubular body or tube may act as an inductor with an effective inductance L, the gap may act as a capacitor with an effective capacitance C, and the conductive material of the tubular body may act as a resistor with an effective resistance R. Based on the induced alternating current in the LGR transverse to the longitudinal axis of the tubular body, for example, in the circumferential direction of the tubular body or LGR, a substantially uniform magnetic field (Biot-Savart law) substantially aligned with or parallel to the longitudinal axis can be generated in the internal volume, core, or ring of the tubular body, and a substantially uniform electric field can be generated between opposite walls or portions of the defined gap or gap portion of the LGR. As described above, the alternating magnetic field can be located or confined within the core or ring of the tubular body, while the alternating electric field can be confined within the gap, allowing the magnetic and electric fields to be separated or isolated from each other. In other words, the alternating electric field can remain unaffected by the alternating magnetic field, and vice versa, which allows one or both fields to be used independently to heat the matrix or a portion thereof.

[0022] On the other hand, a toroidal LGR can be obtained by joining the two ends of a tubular or cylindrical LGR to form a closed structure. The magnetic field can be confined within the resonator of the toroidal or donut-shaped LGR or within the "ring" of the toroidal LGR. A gap can be formed on the inner or outer periphery of the ring or ring portion and extend along at least a portion of its periphery.

[0023] Furthermore, a helical LGR can refer to an LGR having a basic helical body or cross-section, for example, when at least two opposite portions of a tubular LGR overlap each other along the circumferential direction of the tubular LGR and are spaced apart from each other in the radial direction.

[0024] Furthermore, a multi-ring LGR may include multiple rings or ring portions formed by the body of the LGR. Similarly, a multi-gap LGR may include multiple gaps formed in the body of the LGR.

[0025] The annular gap resonator may be at least partially arranged in a cylinder or container, which may be at least partially filled with an aerosol generating matrix or may be at least partially filled with an aerosol generating matrix. The cylinder or container may be connectable to (a) an external power supply and / or (b) a power circuitry of an aerosol generating apparatus, the external power supply being configured to drive the annular gap resonator, and the power circuitry being configured to drive the annular gap resonator. Therefore, an aerosol generating apparatus according to this disclosure may include an annular gap resonator at least partially arranged in a cylinder configured to contain an aerosol generating matrix. Such a cylinder may be attached or connected to another portion of the aerosol generating apparatus, which may include a power circuitry for driving the annular gap resonator. Alternatively or additionally, the cylinder having the annular gap resonator may be connected or attached to an external power supply, which may be, for example, a handheld device or a handheld portion of an aerosol generating apparatus.

[0026] Therefore, the aerosol generating apparatus according to this disclosure can refer to an apparatus, such as a handheld device, which may include an annular resonator and optional additional electronic components, such as a power supply circuit system for driving or supplying power to the LGR. In one example, the aerosol generating matrix or an aerosol generating article comprising the matrix may, for example, be at least partially inserted into the aerosol generating apparatus in the form of a rod.

[0027] However, alternatively or additionally, the aerosol generating apparatus according to this disclosure may refer to a device in the form of a cylinder or container, in which the LGR is at least partially arranged. Optionally, one or more additional components, such as at least one delivery ring and / or at least a portion of the power supply circuitry, may also be arranged in the cylinder or container. Such aerosol generating apparatus in the form of a cylinder or container may be attached to or coupled to another part of the aerosol generating apparatus or to another device, such as an accompanying device or an external power supply, to drive the LGR or to power the LGR to generate aerosols. Such systems may also be referred to as two-part systems and may be used particularly advantageously with liquid matrices, but are not limited thereto.

[0028] It should be noted that the features, functions, and / or components of an external power supply device may be similar to or identical to those of the power supply circuit system, as described above and below. Therefore, any disclosure regarding the power supply circuit system presented herein applies equally to the external power supply device, and vice versa.

[0029] The aerosol generation apparatus may further include an aerosol generation matrix, wherein the annular gap resonator may be configured to receive at least a portion of the aerosol generation matrix, for example, such that at least a part or portion of the LGR surrounds or encapsulates at least a portion of the matrix. Optionally, the aerosol generation matrix and the annular gap resonator may be at least partially arranged in a cylinder, such as a common cylinder. The cylinder may be pre-filled with the matrix and cannot be refilled, or the cylinder may be refilled with the matrix by the user.

[0030] The aerosol generating apparatus may further include at least one conductive transport ring configured to induce eddy currents in at least a portion of the annular resonator and / or configured to generate electromagnetic oscillations in at least a portion of the annular resonator. The at least one transport ring may refer to a coupling ring configured and / or arranged to generate an alternating magnetic field to induce alternating currents or eddy currents within at least a part or portion of the LGR. Depending on the type, shape, or form of the LGR used, the at least one transport ring may be arranged on the outside or at the end of the LGR, for example in the case of a tubular LGR, or within a portion of the LGR, for example in the case of a ring-shaped LGR. Additionally, multiple transport rings may be used to drive one or more LGRs of the aerosol generating apparatus.

[0031] At least one delivery ring and a ring gap resonator, along with an optional aerosol generating matrix, can be arranged within a cylinder or container. Furthermore, the cylinder can be configured, for example, electrically and / or mechanically connected to (a) an external power supply device and / or (b) a power circuit system of the aerosol generating device, the external power supply device being configured to drive the ring gap resonator, and the power circuit system being configured to drive the ring gap resonator.

[0032] The aerosol generating apparatus may further include a power supply circuit system or circuit configured to drive the annular resonator to heat at least a portion of the aerosol generating matrix by exciting electromagnetic oscillations in at least a portion of the annular resonator. To supply electrical energy, the aerosol generating apparatus may include one or more energy storage devices, such as batteries, accumulators, capacitors, etc. Alternatively or additionally, the aerosol generating apparatus may be connected to or powered by a power grid.

[0033] Optionally, the aerosol generating apparatus may include a user interface configured to receive one or more user inputs, the user interface including, for example, user-actuable elements. Based on the user input, the aerosol generating apparatus may be configured to activate a power circuit system to drive the LGR in order to generate aerosols. For this purpose, the aerosol generating apparatus may optionally include a control circuit system having one or more processors or controllers, the control circuit system being coupled to the power circuit system.

[0034] The power supply circuit system can be configured to excite electromagnetic oscillations in the annular resonator at or near the resonant frequency of the annular resonator. As mentioned above, the induced alternating current reaches its maximum value at or near the resonant frequency of the LGR, which in turn can produce the maximum heating effect achievable with the LGR at certain power levels or power inputs. Therefore, driving the LGR at or near the resonant frequency allows for energy-efficient and rapid heating. As used herein, "at or near the resonant frequency" can mean the resonant frequency within a certain relative deviation, for example, within a maximum relative deviation of about 30%, 25%, 20%, 15%, 10%, or 5%.

[0035] The power supply circuitry can be configured to drive the annular gap resonator such that an alternating magnetic field can be generated, for example, in the ring or ring portion of the annular gap resonator, such as in the core, the ring or ring portion being configured to receive at least one portion of the aerosol-generating matrix. Therefore, at least one portion of the matrix can be arranged within the ring or ring portion of the LGR such that the LGR can at least partially surround at least one portion of the matrix. Due to the uniform alternating magnetic field generated by the LGR and applied to the matrix, the matrix, or at least one portion thereof, can be uniformly heated, for example, to a predetermined or desired temperature suitable for aerosol generation.

[0036] Alternatively or additionally, the power supply circuitry can be configured to drive the annular gap resonator such that an alternating electric field can be generated in the gap or gap portion of the annular gap resonator, the gap or gap portion being configured to receive at least one portion and / or at least another portion of the aerosol-generating matrix. Thus, at least one portion and / or at least another portion of the matrix can be arranged within the gap or gap portion of the LGR such that the LGR can at least partially surround at least one (other) portion of the matrix. Due to the uniform alternating electric field generated by the LGR and applied to the matrix, the matrix or at least one (other) portion thereof can, for example, be uniformly heated to a predetermined or desired temperature suitable for aerosol generation.

[0037] Typically, the power supply circuitry can be configured to drive the annular gap resonator based on inductive coupling. For example, the power supply circuitry can be configured to drive the annular gap resonator based on inducing eddy currents, for example, flowing transversely to the longitudinal axis of the annular gap resonator.

[0038] For example, the power supply circuitry may include at least one conductive delivery ring or coupling ring, for instance, disposed at the end or side of the ring gap resonator or within the ring gap resonator. The power supply circuitry may be configured to drive the ring gap resonator based on supplying an alternating current to the at least one delivery ring. This alternating current can generate an alternating magnetic field around the delivery ring, which in turn can induce eddy currents in the LGR or at least a portion thereof. These eddy currents can then generate an alternating magnetic field within the ring or ring portion of the LGR, and an alternating electric field in the gap or gap portion of the LGR, one or both of which can advantageously be used to uniformly heat the substrate.

[0039] For example, at least one delivery ring of the power supply circuit system can be arranged coaxially with the ring or portion of the ring gap resonator. This ensures effective inductive coupling between the delivery ring and the LGR.

[0040] In one example, at least one delivery loop can be formed from the end of the inner conductor of the coaxial cable, which is short-circuited to the outer conductor of the coaxial cable. In other words, the delivery loop can be formed as a portion of the coaxial cable as a loop, wherein the outer conductor can be removed, and optionally the outer jacket and insulation layer can be removed. The center cable of the coaxial cable can then be short-circuited to the remainder of the outer conductor. The center cable and the outer conductor can provide two electrical terminals between which an alternating current can be generated to drive the LGR. An advantage of this design of the delivery loop is that only the delivery loop generates the magnetic field, while the rest of the coaxial cable can be shielded.

[0041] Furthermore, the frequency of the alternating current operating in the delivery ring can be similar to, the same as, or at least proportional to the frequency of the alternating magnetic field generated in the LGR. Therefore, the power supply circuitry and / or control circuitry of the aerosol generating apparatus can be configured to adjust, change, and / or control the temperature at which at least one portion of the matrix is ​​heated or should be heated, based on adjusting, changing, and / or controlling the frequency of the alternating current supplied to the delivery ring and / or based on adjusting, changing, and / or controlling the frequency of the alternating magnetic field generated in the LGR. Thus, precise temperature control can be provided. Alternatively or additionally, the intensity of the alternating current in the delivery ring, the intensity of the alternating magnetic field in the LGR, the frequency of the alternating electric field in the LGR, and / or the intensity of the alternating electric field in the LGR can be adjusted, changed, and / or controlled.

[0042] Alternatively or additionally, the power supply circuitry can be configured to drive the annular gap resonator based on capacitive coupling. For example, the power supply circuitry can include one or more electrodes configured to capacitively couple to a capacitor formed by a slit or gap in the annular gap resonator. In other words, the power supply circuitry can be configured to capacitively induce an alternating electric field in the capacitor formed by the slit or gap in the annular gap resonator. The one or more electrodes can be configured to generate an alternating electric field that can be capacitively coupled to a capacitor formed or defined by a gap or slit in the LGR. Based on adjusting, changing, and / or controlling one or both of the frequency and field strength of the alternating electric field generated by the one or more electrodes, the power supply circuitry and / or the control circuitry of the aerosol generating device can be configured to adjust, change, and / or control the temperature at which at least one portion of the matrix is ​​heated or should be heated.

[0043] Alternatively or additionally, the power supply circuit system may include an electromagnetic wave generator configured to excite electromagnetic oscillations, eddy currents, alternating magnetic fields and / or alternating electric fields in at least a portion of the annular gap resonator to drive the annular gap resonator.

[0044] The aerosol generating apparatus may further include a heating chamber or heating compartment configured to receive at least a portion of the aerosol generating matrix and / or an aerosol generating article comprising the aerosol generating matrix. The heating chamber or compartment may, for example, be arranged within the housing of the aerosol generating apparatus. Optionally, a toroidal resonator may be at least partially arranged in the heating chamber or compartment and configured, for example, to surround at least a portion of the aerosol generating matrix along its periphery.

[0045] In this example, the annular gap resonator may be substantially tubular. In other words, the annular gap resonator may be a tubular or cylindrical annular gap resonator. In this configuration, the longitudinal axis of the annular gap resonator may extend substantially parallel to the insertion direction of the aerosol generating apparatus, along which at least a portion of the aerosol generating matrix and / or the aerosol generating article comprising the aerosol generating matrix may be at least partially inserted into the aerosol generating apparatus.

[0046] The annular resonator may include a tubular body defining a ring, ring portion, or core of the annular resonator, the ring, ring portion, or core being configured to receive and / or at least partially surround at least one portion of the aerosol generating matrix, wherein the annular resonator may be configured to heat at least one portion of the aerosol generating matrix based on generating an alternating magnetic field within the ring, ring portion, or core of the annular resonator.

[0047] Alternatively or additionally, the annular gap resonator may include a tubular body having a slit extending along at least a portion or the entire length of the tubular body. For example, the slit may extend parallel to the longitudinal axis of the annular gap resonator or its tubular body. Alternatively, the slit may extend transversely to the longitudinal axis, for example, in a spiral manner along the length of the tubular body.

[0048] The annular resonator may include a tubular body having a slit defining a gap or gap portion of the annular resonator, the gap or gap portion being configured to receive and / or surround at least one portion and / or at least another portion of the aerosol-generating matrix. The annular resonator may be configured to heat at least one portion and / or at least another portion of the aerosol-generating matrix based on generating an alternating electric field within the gap or gap portion of the annular resonator.

[0049] As described above, an aerosol generation apparatus may include, for example, multiple annular gap resonators arranged coaxially or adjacent to each other. The same or different types of annular gap resonators may be used to heat the same or different aerosol generation substrates or articles.

[0050] A second aspect of this disclosure relates to the use of an annular gap resonator in an aerosol generating apparatus or system to heat at least a portion of an aerosol generating matrix, said aerosol generating matrix optionally being at least partially insertable into said aerosol generating apparatus. Any features and / or elements of the aerosol generating apparatus or system described above and below are equally applicable to the use of the aerosol generating apparatus or system.

[0051] According to a third aspect of this disclosure, an aerosol generating article is provided for an aerosol generating apparatus (e.g., an aerosol generating apparatus including an annular resonator), said annular resonator being configured to heat at least one portion of the aerosol generating article. The aerosol generating article may include at least one of the following:

[0052] - A first portion, wherein the first portion is arranged, shaped, configured, and / or formed to fit within the ring of the annular gap resonator; and

[0053] - The second part is arranged, shaped, configured and / or formed to fit into the gap of the annular resonator.

[0054] The aerosol generating article may also include an annular gap resonator configured to heat one or both of a first portion and a second portion of the aerosol generating article. In the context of this disclosure, an "aerosol generating article including an annular gap resonator" may also be referred to as an "aerosol generating apparatus." In other words, as stated above and below, an aerosol generating article including one or both of a first portion and a second portion of the aerosol generating article and an annular gap resonator may be referred to as an "aerosol generating apparatus."

[0055] Therefore, any features and / or elements described with reference to the aerosol generating apparatus described above and below are equally applicable to one or more aerosol generating articles described above and below.

[0056] In one example, the first portion may be substantially cylindrical. The first portion of the aerosol-generating article may be shaped and sized to substantially fit within the ring or ring portion of the LGR. Thus, the first portion of the aerosol-generating article may be formed correspondingly to the ring or ring portion of the LGR. Such corresponding geometry can support or ensure uniform heating of the first portion of the aerosol-generating article.

[0057] Alternatively or additionally, the second part may be substantially rod-shaped and / or formed as a parallelepiped. The second part of the aerosol-generating article may be shaped and sized to substantially fit within the gaps or gap portions of the LGR. Thus, the second part of the aerosol-generating article may be formed correspondingly to the gaps or gap portions of the LGR. Such corresponding geometries can support or ensure uniform heating of the second part of the aerosol-generating article.

[0058] The aerosol generating article can be key-shaped. For example, a second portion can protrude from the first portion of the aerosol generating article in a fin-like manner. Therefore, the second portion can be coupled to or attached to the first portion of the aerosol generating article, allowing the aerosol generating article to be formed in a substantially key-shaped shape. In other words, the second portion can constitute the teeth of a substantially key-shaped aerosol generating article. Therefore, the aerosol generating article can be shaped and sized such that the first portion fits within a ring of the LGR, and the second portion fits within a gap in the LGR. Thus, one or both of the magnetic field generated by the LGR within the ring and the electric field generated by the LGR within the gap can be used to heat the first and / or second portions of the substrate.

[0059] A first portion of the aerosol-generating article may include a first aerosol-generating matrix configured for heating to generate aerosols, and a second portion of the aerosol-generating article may include a second aerosol-generating matrix configured for heating to generate aerosols, the second aerosol-generating matrix being different from the first aerosol-generating matrix. In other words, the first and second portions of the aerosol-generating article may include differentiated or different matrices. The first and second matrices may differ in type or form, such as liquid or solid matrices, and / or in any other property, such as material density, density of the aerosol-generating material or substance of the matrix, material composition, one or more components, or any other property or characteristic of the matrix. Alternatively or additionally, the first and second aerosol-generating matrices may differ from each other in one or more aspects of humidity level, tobacco type, flavor, and taste, for example, in the taste or flavor of the gas stream containing the generated aerosols.

[0060] In one example, the first aerosol generating matrix may include a sensor or sensor material configured to be heated based on induction heating. Alternatively or additionally, the second aerosol generating matrix may be configured to be heated based on microwave heating and / or may not include a sensor or sensor material. For example, the second aerosol generating matrix may have a minimum humidity level, such as residual humidity, to allow for efficient and effective microwave heating when exposed to an alternating electric field in the gap of the LGR.

[0061] The aerosol generating article may further include a mouthpiece and an airflow path configured to transport aerosols toward the mouthpiece. The airflow path may include a first flow path portion connected to a first portion of the aerosol generating article and configured to transport aerosols generated in the first portion of the aerosol generating article toward the mouthpiece. Alternatively or additionally, the airflow path may include a second flow path portion connected to a second portion of the aerosol generating article and configured to transport aerosols generated in the second portion of the aerosol generating article toward the mouthpiece. Through the first and / or second airflow path portions, the aerosols generated by the first and / or second portions of the aerosol generating article can be efficiently guided or directed toward the mouthpiece, which can enhance the user's overall experience, such as in terms of taste or flavor.

[0062] Optionally, the second flow path portion can be connected to the first flow path portion, allowing the aerosols generated in the first and second portions of the aerosol-generating article to mix as they are transported towards the mouthpiece via the airflow path. By mixing the aerosols generated in the first and second portions, or by mixing the corresponding airflows carrying the aerosols from the first and second portions towards the mouthpiece, the overall user experience can be further improved. In particular, a substantially constant taste or flavor can be provided across multiple subsequent uses.

Also in this configuration, substantially uniform heating can be ensured.

[0073] The receptor or receptor material may include one or more particles of ferromagnetic material. For example, one or more particles may be disposed within an aerosol-generating matrix, such as randomly disposed and / or oriented within the matrix. For instance, a solid matrix, such as a tobacco casting leaf composed of the matrix, may be at least partially impregnated with a liquid containing one or more particles to randomly and homogeneously dispose the particles within the matrix. In other words, the aerosol-generating matrix or at least a portion thereof may be impregnated with a fluid containing one or more particles. In the case of a liquid matrix, one or more particles may be dissolved in the liquid matrix to provide a homogeneous particle distribution.

[0074] Alternatively or additionally, one or more particles can be deposited on the aerosol-generating matrix, for example, as a coating deposited onto a solid matrix. Thus, one or more particles can be used to coat the aerosol-generating matrix. For example, the one or more particles can be deposited on or onto the aerosol-generating matrix by means of or based on physical vapor deposition.

[0075] Optionally, the one or more particles may be or may include magnetic iron oxide particles.

[0181] Figure 1 A cross-sectional view of an aerosol generation system 10 having an aerosol generation apparatus 12 and an aerosol generation article 14 is shown. Figure 1 It can be used in particular to illustrate conventional aerosol generation systems or devices currently in use and the heating technologies implemented therein.

[0182] exist Figure 1 In the example shown, the aerosol-generating article 14 is at least partially received by the aerosol-generating apparatus 12. For example, at least a portion of the aerosol-generating article 14 may be arranged in the heating chamber 11 of the aerosol-generating apparatus 12. Figure 1 An exemplary aerosol generating article 14 is in rod form and includes an aerosol generating matrix 16 that substantially fills the internal volume of the aerosol generating article 14. Such an aerosol generating article 14 may also be referred to as a user-replaceable “consumable” and the matrix may also be referred to as a “sensory medium”.

[0183] To heat the aerosol generating article 14 and / or its aerosol generating matrix 16, the aerosol generating apparatus 12 includes resistance heating blades 18 for resistively heating the matrix 16 based on the supply of electrical energy to the blades 18. The heating blades 18 may be arranged, for example, at one end at the bottom of the heating chamber 11 and / or may be arranged in the central portion of the heating chamber 11. The heating chamber 11 may be defined by a hollow core, such as a tubular core, within the internal volume of the aerosol generating apparatus 12. Furthermore, the heating blades 18 may be coupled to or connected to electronic components 13 of the aerosol generating apparatus 21, such as a power supply circuit system 13 for supplying power to the heating blades 18.

[0184] The aerosol generating article 14 can be inserted into the aerosol generating apparatus 12 such that the heating blade 18 is preferably arranged at the center of the aerosol generating article 14 and is at least partially surrounded by its aerosol generating matrix 16. To increase the effective heating surface of the heating blade 18, the heating blade 18 can be thin and flat. Therefore, the blade 18 can be subjected to mechanical deformation or deterioration, especially due to the repeated processes of inserting and removing the aerosol generating article 14 into the apparatus 12, as the heating blade 18 can be pushed into and pulled out of the matrix 16 during these processes.

[0185] Furthermore, during each insertion and removal process, the heating blade 18 may be oriented or arranged differently relative to the aerosol generating matrix 16, and the internal configuration of the aerosol generating article may vary depending on the usage process. In the case of the rod-shaped aerosol generating article 14, for example, the aerosol generating matrix 16 may comprise at least one longitudinally folded tobacco cast leaf (“TCL”) sheet compressed into a strip. Depending on the orientation of the blade 18 within the consumable 14, the folds of the matrix 16 (“TCL folds”) may have an orientation that varies from parallel to perpendicular relative to the heating blade 18. Specifically, the folds may be randomly oriented relative to the blade 18. Thus, different aerosol generating articles 14, such as articles 14 used in different usage processes, may be heated differently by the blade 18, which can affect aerosol generation and result in different user experiences in various usage processes. However, preferably, a consistent user experience should be provided in various usage processes.

[0186] In addition, the heat received by different portions 16a, 16b or volumes 16a, 16b of the matrix 16 within the aerosol generating article 14 can depend on the distance of the respective portions 16a, 16b from the heating blade 18. It has been reported that the planar geometry of the heating blade 18, relative to, for example, the cylindrical shape of the aerosol generating article 14, can generate less heating in portions 16b located away from the blade 18, for example, in directions transverse to or perpendicular to the blade 18 and / or the longitudinal direction of the aerosol generating article 14, compared to portions 16a located closer to the blade 18. Therefore, some portions of the matrix 16 relatively far from the blade 18, such as portion 16b, may be insufficiently heated to generate aerosols, or may not be heated to a sufficiently high temperature to generate aerosols, while other portions located closer to the blade 18, such as portion 16a, may be overheated or heated to too high a temperature. Thus, some portions may be wasted, while others may be overheated.

[0187] Figure 2 A perspective view of a portion of the aerosol generation system 10 is shown. Unless otherwise stated, Figure 2 System 10 includes reference Figure 1 The systems described have the same characteristics, functions, and components.

[0188] exist Figure 2 In the illustrated example, a receptor 18 or receptor material 18 is disposed at the center of the aerosol generating article 14 or consumable 14 to heat the aerosol generating matrix 16 contained in the aerosol generating article 14 based on induction heating. The receptor 18 may, for example, comprise a planar metal strip and include a material that is both conductive and resistive, such as a ferromagnetic material or stainless steel, positioned at the center of the aerosol generating article 14 and surrounded by the aerosol generating matrix 16. Preferably, the central longitudinal axis 15 of the receptor 18 is substantially aligned with the central longitudinal axis 15 of the aerosol generating article 14. Furthermore, the length of the receptor along axis 15 may substantially match the length of the aerosol generating article 14 and / or the width of the receptor 18 may be slightly smaller than the width of the article 14, wherein the width may be measured transversely to the longitudinal axis 15.

[0189] When a user activates the aerosol generating device 12 or its heating system, an alternating electromagnetic field is generated in the device 12, thereby generating or inducing eddy currents in the sensor 18, and the dissipation of these currents in the sensor 18 is based on Joule's law to heat the sensor 18 and the surrounding matrix 16 in order to generate aerosols.

[0190] For example, when with Figure 1 Compared to other system designs, when using induction heating, the receptor strip 18 can be mechanically robust. However, such a system 10 can still exhibit variations in heating depending on the distance between the heated portion or volume of the substrate 16 and the receptor 18 (in a direction transverse to or perpendicular to axis 15) and depending on the structure in the substrate 16, such as the relative orientation of folds relative to the receptor 18.

[0191] Homogeneous induction heating of consumable 14 or aerosol generating article 14 can adequately address the relationship between the spatial distribution and characteristics of the receptor 18 or receptor material 18, for example, taking into account the so-called "skin effect" (the skin effect refers to the fact that eddy currents are mainly retained on the surface of the receptor material 18, especially when high-frequency currents are induced) and the spatial distribution and characteristics of the alternating magnetic field, such as the frequency of the magnetic field. For example, the total heat transferred to a region or portion of the aerosol generating article 14 (where the intensity of the alternating magnetic field is low and the intensity of the receptor surface or material is high) can be the same as that of another region or portion with opposite characteristics (e.g., high intensity of the alternating magnetic field, but low intensity of the receptor surface or material).

[0192] Furthermore, the electronics used in the aerosol generation system 10 and device 12 may be limited with respect to the electromagnetic radiation or waves emitted by device 12 or system 10. For example, microwave frequencies in an unlicensed range, such as the 2.4 GHz ISM band (“Industrial, Scientific, and Medical Band”), may be used, and / or the power level may be below about 15 W, below about 10 W, or preferably below about 5 W. This low power level can save energy and can extend the charging cycle time of device 12 in the case of battery-powered device 12 or system 10.

[0193] In addition, the aerosol-generated articles 14, particularly rod-shaped articles, typically have a diameter of about 0.3-1.5 cm, for example 0.5-1.0 cm or 0.7-0.8 cm, and a length of about 0.5 cm to 2 cm, for example about 1.2 cm.

[0194] The heating temperature reached by the substrate 16 or the predetermined or desired temperature of the substrate 16 may be approximately 100°C to 300°C, for example, approximately 200°C to 250°C.

[0195] Figure 3 An aerosol generating apparatus 100 for generating aerosols is shown. Unless otherwise stated, Figure 3 The aerosol generating device 100 includes a reference Figure 1 and Figure 2 The aerosol generating apparatus 12 and system 10 described have the same features, functions and components.

[0196] Figure 3 The aerosol generating apparatus 100 shown is configured to receive at least a portion of an aerosol generating matrix 200 in order to generate an aerosol based on heating the matrix 200. The matrix 200 may, for example, correspond to matrix 16, and may be derived from a matrix corresponding to, as shown in the reference... Figure 1 and Figure 2 The described article 14 is essentially composed of a rod-shaped aerosol generating article 202. Such an aerosol generating article 202 may, for example, include a mouthpiece 204 for a user to experience or inhale the aerosol generated by the aerosol generating device 100 during use.

[0197] Alternatively or additionally, the matrix 200 may include a liquid that can be supplied to the aerosol generating apparatus 100, for example in the form of a cylinder or container that can be refilled with the matrix 200.

[0198] In order to heat the matrix 200 or at least a portion thereof, the aerosol generating apparatus 100 includes an annular resonator 110, which is configured to heat at least a portion of the aerosol generating matrix 200 based on one or both of induction heating and microwave heating, as described in detail above and below herein.

[0199] The annular gap resonator 110 can be, for example, one of a cylindrical annular gap resonator, a tubular annular gap resonator, a ring annular gap resonator, a spiral annular gap resonator, a multi-ring annular gap resonator, and a multi-gap annular gap resonator.

[0200] The aerosol generating apparatus 100 may also include, for example, a plurality of annular gap resonators 110 arranged coaxially with the longitudinal axis 111 of the aerosol generating apparatus 100, LGR 110 and / or aerosol generating article 202. In one example, at least a portion of the annular gap resonators 110 may be arranged in the heating chamber 112 of the aerosol generating apparatus 100.

[0201] The aerosol generating apparatus 100 further includes at least one conductive transport ring 150, which is configured to induce eddy currents, alternating currents, and / or electromagnetic oscillations within or in at least a part or portion of the annular gap resonator 110. Figure 3 In the example shown, the delivery ring 150 may be integrated or arranged within the housing of the aerosol generating device 100, which may be a handheld device configured to at least partially receive the aerosol-generated article 202. For example, the aerosol-generating article 202 may be inserted along an insertion direction 113 parallel to the longitudinal axis 111 of the aerosol generating device 100, LGR 110, and / or the aerosol-generating article 202.

[0202] Furthermore, the transport ring 150 may be arranged at or near the end of the annular gap resonator 110, for example, at least partially arranged in the heating chamber 112. Alternatively or additionally, at least one transport ring 150 may be integrated or arranged in a part or portion of the annular gap resonator 110.

[0203] The aerosol generating apparatus 100 also includes a power supply circuit system 160 configured to drive the annular gap resonator 110 and / or the delivery ring 150 to heat at least one portion of the aerosol generating matrix 200. The delivery ring 150 may be part of the power supply circuit system 160 of the aerosol generating apparatus 100. Specifically, the power supply circuit system 160 may be configured to excite electromagnetic oscillations in the annular gap resonator 110 at or near the resonant frequency of the annular gap resonator 110. For example, the power supply circuit system 160 may be configured to drive the annular gap resonator 110 such that an alternating magnetic field is generated in a part or portion of the annular gap resonator 110 configured to receive and / or surround at least one portion of the aerosol generating matrix 200, particularly in the ring of the annular gap resonator 110. Alternatively or additionally, the power supply circuit system 160 may be configured to drive the annular resonator 110 such that an alternating magnetic field is generated in a part or portion of the annular resonator 110 configured to receive and / or surround at least one portion (or another portion) of the aerosol generation matrix 202, particularly in the ring of the annular resonator 110.

[0204] The power supply circuit system 160 can also be configured to drive the ring gap resonator 110 based on inductive coupling, for example, by supplying an alternating current to at least one delivery ring 150, which generates an alternating magnetic field near the delivery ring 150, which in turn induces eddy currents in the ring gap resonator 110.

[0205] Alternatively or additionally, the power supply circuit system 160 may be configured to drive the annular gap resonator 110 based on capacitive coupling. For example, the power supply circuit system 160 may include one or more electrodes configured to capacitively couple to a capacitor formed by the slits or gaps of the annular gap resonator 110, thereby capacitively inducing an alternating electric field in the capacitor formed by the slits or gaps of the annular gap resonator 110.

[0206] Alternatively or additionally, the power supply circuit system 160 may include an electromagnetic wave generator configured to excite electromagnetic oscillations in at least a portion of the annular gap resonator 110 to drive the annular gap resonator.

[0207] The aerosol generating device 100 also includes at least one energy storage device 170, such as at least one battery, accumulator, or capacitor, to supply electrical energy during use of the device 100. Alternatively or additionally, the aerosol generating device 100 may be powered by a power grid or any other power source.

[0208] Figure 3The exemplary aerosol generating apparatus also includes a control circuitry system 180 for controlling one or more functions of the control device 100. For example, the control circuitry system 180 may be configured to actuate, activate, and / or deactivate the power circuitry system 160 to start or stop aerosol generation.

[0209] The device 100 may also include a user interface 190 for receiving one or more user inputs. The user interface 190 may be, for example, one or more of a switching element, a user-actuable element, a button, a touch interface, etc. The control circuitry 180 may be configured to receive or process one or more user inputs received at the user interface 190, and to actuate or control the power circuitry 160 in a manner corresponding to, dependent on, and / or responsive to one or more user inputs.

[0210] It should be noted that Figure 3 The aerosol generating apparatus 100 and aerosol generating article 202 shown can constitute an aerosol generating system 500 in the sense of this disclosure.

[0211] Figure 4 An aerosol generation system 500 for generating aerosols is shown. Unless otherwise stated, Figure 4 The aerosol generation system 500 includes a reference Figures 1 to 3 The aerosol generating devices 12, 100 and systems 10, 500 described have the same features, functions and components.

[0212] Figure 4 The exemplary system 500 shown includes an aerosol generating apparatus 100, which includes an annular gap resonator 110, which is at least partially arranged and / or integrated in a cylinder 130 or container 130 configured to contain or store an aerosol generating matrix 200. The cylinder 130 may have any suitable geometry, shape, form, and / or size.

[0213] The matrix 200 may be, for example, a liquid, a liquid matrix, a fluid, or a fluid matrix. However, the matrix 200 may alternatively or additionally include a solid component or a solid matrix material.

[0214] Optionally, the matrix 200 may include a sensor or sensor material that is heated by induction heating of the matrix 200 using the annular resonator 110. For example, one or more particles of ferromagnetic material, such as iron oxide particles, may be arranged or disposed in the matrix 200. However, the matrix 200 or at least a portion thereof may alternatively or additionally be heated by microwave heating using the annular resonator 110, as described in detail above and below herein.

[0215] The aerosol generating device 100 and / or its cylinder 130 may be pre-filled with matrix 200, or may be refilled by the user as needed.

[0216] To generate aerosols, the aerosol generating device 100 can be coupled, mounted, and / or attached to an external power supply device 250 for driving or powering the annular gap resonator 110, such as... Figure 3 As indicated by arrow 205. For example, the aerosol generating device 100 can be at least partially inserted into the external power supply device 250.

[0217] The external power supply device 250 may be, for example, a handheld device, which may have the same characteristics as the reference device. Figure 3 The described aerosol generating device 100 has similar or identical functions and features. Specifically, the external power supply 250 device may include one or more of a power supply circuit system 160, an energy storage device 170, a control circuit system 180, and a user interface 190, as referenced. Figure 3 As stated above.

[0218] In addition, the aerosol generation system 500 includes at least one delivery ring 150 for driving the annular gap resonator 110. Figure 4 The delivery ring 150 of the system 500 shown is exemplary integrated into or disposed on the cylinder 130. However, alternatively or additionally, at least one delivery ring 150 may be integrated into an external power supply unit 250.

[0219] To electrically connect or couple the aerosol generating device 100 (or cylinder 130) to the power supply device 250, the aerosol generating device 100 and / or cylinder 130 may include one or more electrical connectors 120 for electrically connecting the delivery ring 150 or other electronic components to the power circuitry 160 of the external power supply device 250. For example, a mechanical connection from the aerosol generating device 100 to the external power supply device 250 can establish an electronic connection. As an alternative to or supplement to the one or more electrical connectors 120, inductive or capacitive coupling may be used, for example, to drive the annular gap resonator 110 through the wall of the cylinder 130.

[0220] When activated by the user, the external power supply 250 can drive the annular resonator 110, which is at least partially arranged in the cylinder 130, to heat the matrix 200 and generate an aerosol. For example, in response to the user's inhalation, an airflow carrying the generated aerosol can be delivered from the heating chamber 112 to the mouthpiece 204 via the airflow path 210.

[0221] Generally, any type of annular gap resonator 110, such as cylindrical annular gap resonators, tubular annular gap resonators, ring annular gap resonators, spiral annular gap resonators, multi-ring annular gap resonators, and multi-gap annular gap resonators, can be used. Figure 3 and Figure 4The apparatus 100 and system 500 shown are used. Additionally, any type of substrate or multiple substrates 200 can be used to heat the substrate 200 based on induction heating and / or microwave heating using the annular gap resonator 110. Optionally, the sensor or sensor material may consist of one or more substrates 200 for induction heating.

[0222] Figure 5A and Figure 5B Each shows a detailed view of a portion of the aerosol generating apparatus 100 used to generate aerosols. Unless otherwise stated, Figure 5A and Figure 5B The aerosol generating device 100 includes a reference Figures 1 to 4 The aerosol generating devices 12, 100 and systems 10, 500 described have the same features, functions and components.

[0223] Figure 5A and Figure 5B The exemplary aerosol generating apparatus 100 depicted includes a cylindrical or tubular annular resonator 110, which is configured to heat one or more portions 200a, 200b of the aerosol generating matrix 200.

[0224] The annular gap resonator 110 includes a tubular body 114 that defines or at least partially surrounds a ring 115 or core 115 of the annular gap resonator 110, the ring or core being configured to receive and / or at least partially surround at least one portion or part 200a of the aerosol generation matrix 200. Thus, the ring 115 may refer to a compartment formed by or at least partially closed by at least one portion of the annular gap resonator 110, wherein the ring 115 may be configured to at least partially surround or enclose at least one portion 200a of the matrix 200. The annular gap resonator 110 may be configured to heat at least one portion 202a of the aerosol generation matrix 200 based on the generation of an alternating magnetic field within the ring 115 or core 115 of the annular gap resonator 110.

[0225] The longitudinal axis 111 of the annular gap resonator 110 may extend substantially parallel to the insertion direction 113 of the aerosol generating apparatus, along which at least a portion 200a of the aerosol generating matrix 200 (and / or an aerosol generating article comprising the aerosol generating matrix) may be inserted into the aerosol generating apparatus 100 and / or the annular gap resonator 110, at least partially. For example, a substantially rod-shaped aerosol generating article comprising the matrix 200, portions 200a and / or 200b of the matrix 200 may be inserted into the aerosol generating apparatus 100.

[0226] Furthermore, the annular resonator 110 includes a slit 116 extending along the length of the tubular body 113, for example, parallel to the longitudinal axis 111 of the annular resonator 110. The slit defines a gap 117 or gap portion 117 of the annular resonator 110, said gap or gap portion being configured to receive and / or at least partially surround at least a portion 200b of the aerosol generating matrix 200. Thus, the gap 117 or slit 116 may be formed by two opposing portions, walls, or portions 117a, 117b of the annular resonator 110, said opposing portions, walls, or portions being arranged opposite each other along the circumferential direction of the annular resonator 110 and / or laterally or perpendicularly to the longitudinal axis 111. The annular resonator 110 may be configured to heat at least a portion 200b of the aerosol generating matrix 200 based on the generation of an alternating electric field within the gap 117 of the annular resonator 110.

[0227] It should be noted that the substrate 200 may include one or both of substrate portions 200a and 200b. Therefore, the substrate 200 may be shaped and sized to fit within the ring 115 of the annular gap resonator 110. Figure 5A and 5B In the example shown, the substrate 200 can therefore have a basic cylindrical shape and form. Alternatively or additionally, the substrate 200 can be shaped and sized to fit within the gap 117. Figure 5A and Figure 5B In the example shown, the matrix 200 can therefore have a substantially rod-like shape, or it can be formed as a parallelepiped. For illustrative purposes, in Figure 5B The diagram shows a portion 200b of matrix 200 adjacent to aerosol generating apparatus 100. As mentioned, matrix 200 may alternatively comprise two portions 200a and 200b. When two portions 200a and 200b are included, the matrix materials used in these portions 200a and 200b may be substantially similar or identical; for example, the only difference is that portion 200b may include receptors or receptor materials arranged, positioned, and / or housed therein. However, different matrix materials may also be used for portions 200a and 200b. For example, matrix portions 200a and 200b and / or the matrix materials contained therein may differ in one or more aspects of humidity level, tobacco type, flavor, taste, or any other characteristic. Furthermore, different portions 200a and 200b can be combined by the user according to individual needs.

[0228] In short, and exemplarily summarized, a portion 200a of matrix 200, or the matrix corresponding to portion 200a, can be heated by a magnetic field acting on the receptor or the receptor material contained therein. The aerosol-generating article or consumable can be substantially rod-shaped and inserted into the ring 115 or core 115 of LGR 110. Therefore, portion 200a of matrix 200 can be heated based on magnetic heating.

[0229] Preferably, the receptor material in the matrix 200 or portion 200a can be spatially homogeneously distributed within the portion 200a. For example, the receptor material can be small particles of ferromagnetic material inserted into the matrix 200 or its matrix material and / or coated onto the matrix or its matrix material. Alternatively or additionally, the receptor material can be a magnetic fluid or liquid added to and / or coated onto the matrix material, such as a TCL sheet. Since the LGR 110 can provide a nearly uniform alternating magnetic field in its hollow core 115 or ring 115, the portion 200a of the matrix 200 can be heated substantially uniformly to a desired or predetermined temperature. Therefore, the uniformity of heat per volume received by the matrix 200 or its material may depend only on the spatial distribution and properties of the receptor material. Thus, uniform heating of the matrix 200 can be further supported by the homogeneously distributed receptor material in the matrix 200.

[0230] As described above, other types of sensors or sensor materials can be used to heat part 200a based on induction heating. For example, wires or strips of ferromagnetic material can be used as sensors or sensor materials. Alternatively or additionally, ferrite plates can be used as sensors or sensor materials. Alternatively or additionally, materials with... Figure 2 The receptor 18 is similar to the receptor.

[0231] Preferably, the volume percentage of the receptor material in the matrix 200 or portion 200a should be in the range of about 2% to about 30%, for example, about 5% to about 20%, for example, about 10%. Using such volume filling and an exemplary operating or driving frequency of about 2 GHz to 3 GHz, for example, about 2.4 GHz, and a power level of 0.5 W to 5 W, for example, about 1 W, a temperature of about 200°C to 300°C, for example, about 250°C, can be reached after 5 to 30 seconds, for example, after about 20 seconds.

[0232] Referring to a portion 200b of the matrix 200 that can replace or supplement portion 200a, actual heating can be provided by the electric field of the LGR 110 acting on moisture, water molecules, or humidity present in the matrix 200 or portion 200b. In other words, portion 200b can be heated based on microwave heating. Since the LGR 110 can provide a nearly uniform alternating electric field in the side gaps 117 of the LGR 110, portion 200b can be heated uniformly or homogeneously to a desired or predetermined temperature. Therefore, the uniformity of heat per volume received by the matrix 200 or portion 200b may depend only on the spatial distribution and properties of the matrix material, such as humidity. Such heating can be considered as dielectric heating or microwave heating and may require only the minimum humidity level that may exist in the matrix under any circumstances. In other words, the matrix 200 or portion 200b can be heated based on the electrical component of the electromagnetic field generated in the LGR 110, specifically without the need for sensor material in the matrix 200. The residual moisture in the substrate 200 is sufficient to achieve dielectric heating as needed.

[0233] Typically, the LGR 110 can be considered an electromagnetic resonator with properties similar to a classic LCR circuit, which is equivalent to a circuit consisting of an inductor of inductance L, a capacitor of capacitance C, and a resistor of resistance R connected in series at a resonant frequency, and optionally a generator. The resonant frequency can refer to the frequency of the alternating current operating in the circuit, at which the current reaches its maximum value and / or the circuit impedance is at its minimum. Furthermore, the LGR 110 can generate approximately uniform and isolated electric and magnetic fields, at least in certain regions or portions of the LGR 110. An exemplary type of LGR 110 that can be used to heat the substrate 200 is a tubular LGR 110, such as... Figure 5A and Figure 5B As shown, the conductive tubular body 114 is longitudinally cut by a slit 116 to form a gap 117. The tubular body 114 can act as an inductor L of the circuit, the gap 117 can act as a capacitor C, and the conductive metal composed of LGR 110 can act as a resistor R. For such an LGR 110, an alternating current running transversely to the longitudinal axis 111, for example along the circumferential direction of the LGR 110, in the tubular body 114 can generate a uniform magnetic field substantially aligned with the longitudinal axis 111 of the annular resonator 110 (in Figure 5A (represented by "B" in the original text) (Biot-Savart law) and a uniform alternating electric field is generated between the opposite walls 117a, 117b or portions of 117a, 117b or between the opposite walls or portions forming the gap 117 (in Figure 5A(represented by "E" in Chinese). The specific advantages of these alternating electromagnetic fields generated by the LGR 110 can be seen in their uniformity and their confinement to certain regions or portions of the LGR 110, such as ring 115 and gap 117. The two fields can be physically separated and do not interfere with each other during the heating process, whether it is induction heating in ring 115 or microwave heating in gap 117.

[0234] Possible illustrative and non-limiting physical characteristics or properties of the LGR 110 are summarized below. The dimensions of the LGR 110, such as length and / or width, may be from about 1 / 8 to 1 / 12 of the resonant wavelength, for example, about 1 / 10. For an exemplary target resonant frequency of 2.4 GHz and a phase velocity close to the speed of light, the wavelength can be estimated to be in the range of several centimeters to tens of centimeters, for example, about 10 centimeters, and therefore the dimensions of the LGR 110 may be in the range of several millimeters to several centimeters, for example, from about 0.5 cm to 5 cm, for example, 1 cm.

[0235] The inner diameter of LGR 110 and / or the diameter of the ring portion 115 can be selected to correspond to, for example, the matrix 200 or aerosol generating article to be used in the case of a rod-shaped aerosol generating article comprising a matrix with a receptor. In other words, the outer diameter of the matrix 200 or portion 200a can substantially correspond to the inner diameter of LGR 110 or the diameter of the ring portion 115. For example, the diameter of the ring portion 115 can be slightly larger than the diameter of the matrix 200 or portion 200a. Similarly, the length of LGR 110 can substantially match or correspond to the length of the matrix 200 inserted into the portion 200a of LGR 110 or ring 115.

[0236] The exemplary inner diameter can range from about 0.1 cm to about 10 cm, for example from about 0.5 cm to about 5 cm, or for example from about 0.6 cm to about 1.2 cm. The wall thickness of the tubular body 114 can range from about 0.1 mm to about 2 cm, for example from about 1 mm to about 5 mm, or for example from about 1.5 mm to about 4 mm. The length of the LGR 110 can range from about 0.1 cm to about 10 cm, for example from about 0.5 cm to about 5 cm, or for example from about 0.8 cm to about 1.5 cm. The width of the gap 117 of the LGR 110 can range from about 0.1 mm to about 5 cm, for example from about 0.2 mm to about 1 cm, or for example from about 0.3 mm to about 3 mm.

[0237] The quality factor can be approximately 1600-2000 in the frequency range of 1-6 GHz, which can be an exemplary, non-limiting frequency range. The quality factor Q can be given by the ratio between the energy stored in the resonator and the energy loss per second. The indicated Q value can be quite high, which corresponds to a good energy-to-loss ratio, since the average Q value of other LCR circuits is typically in the hundreds.

[0238] As the material used for LGR 110, any conductive material can be selected, such as copper and / or aluminum.

[0239] As mentioned above, the LGR 110 can be fed or driven by at least one conveyor ring 150, such as Figure 5B As shown. Current can be inductively coupled into the LGR 110 via the feed ring 150. The feed ring 150 can guide the electric ring, which can be arranged coaxially with the LGR 110 relative to the longitudinal axis 111, parallel to the end or face of the LGR 110, and / or close to the end of the LGR 110. Alternating current can be fed to the feed ring 150, which can generate an alternating magnetic field around the ring 150 (Biot-Savart law), and the alternating magnetic field itself can generate transversely moving eddy currents in the LGR 110 and / or the tubular body 114 (Faraday's law of induction). These eddy currents can then generate a uniform alternating magnetic field in the center of the LGR 110 or in the ring 115 and / or an alternating electric field in the gap 117.

[0240] For example, a transport ring 150 can be formed by using a coaxial cable, forming a loop from a portion thereof, and removing the outer conductor, outer jacket, and insulation layer from that portion. The center cable or coaxial cable of the ring can then be short-circuited to the remainder of the outer conductor of the coaxial cable. The center cable and the outer conductor of the coaxial cable can then provide two electrical terminals between which an alternating current can be generated. In this design, only the loop portion of the transport ring can generate a magnetic field, while the other portions of the coaxial cable can be shielded due to its coaxial nature.

[0241] The frequency of the alternating current operating in ring 150 may correspond to or be at least proportional to the frequency of the alternating (electro)magnetic field generated in the tubular body 114 of LGR 110.

Unless otherwise stated, Figure 6 The aerosol generation system 500 includes a reference Figures 1 to 5B The aerosol generating devices 12, 100 and systems 10, 500 described have the same features, functions and components.

[0243] exist Figure 6The image shows a perspective view and a cross-sectional view of an exemplary aerosol generation system 500, which includes an aerosol generation device 100 and a generally cylindrical or rod-shaped consumable or aerosol generation article 202, the aerosol generation article including a matrix 200 having a matrix portion 200a and a mouthpiece 204. The aerosol generation article 202 can be at least partially inserted into the aerosol generation device 100 such that the matrix portion 200a can be accommodated in a ring 115 of an LGR 110 and can be heated by the LGR 110 based on induction heating. The LGR 110 can be driven by at least one delivery ring 150 arranged at the end or bottom of the LGR 110 and / or by an electromagnetic wave generator, as described above.

[0244] Optionally, the gap of LGR 110 can be used to heat another portion 200b (not shown) of the substrate 200 based on microwave heating as described above.

Unless otherwise stated, the aerosol generating article includes components similar to those described in the reference document. Figures 1 to 6 The aerosol generating articles 14 and 202 described have the same features, functions and components.

[0246] Although not limited to this, Figure 7 The aerosol generating article 202 may be particularly suitable or configured for use in or with an aerosol generating apparatus 100 including an annular resonator 110, as particularly with reference to the preceding figures.

[0247] The aerosol generating article 202 includes a first portion 202a disposed and / or formed to fit within the ring 115 of the annular gap resonator 110 of the aerosol generating apparatus 100, and a second portion 202b disposed and / or formed to fit within the gap 117 of the annular gap resonator 110. Optionally, the LGR 110 may be integrated into the aerosol generating article 202.

[0248] The first portion 202a of article 202 may be substantially cylindrical. Alternatively or additionally, the second portion 202b of article 202 may be substantially rod-shaped and / or formed as a parallelepiped, for example, see reference . Figure 5A and Figure 5B As stated above.

[0249] like Figure 7 As can be seen, the aerosol generating article 202 can be key-shaped, wherein a portion 202b can form or constitute the teeth of a key. In other words, the second portion 202b can protrude from the first portion 202a of the aerosol generating article 200 in a fin-like manner.

[0250] Furthermore, the first portion 202a may include a first aerosol generating matrix 200a configured to be heated to generate aerosols, and the second portion 202b may include a second aerosol generating matrix 200b configured to be heated to generate aerosols, the second aerosol generating matrix 200b being different from the first aerosol generating matrix 200a. For example, the first aerosol generating matrix 200a may include a receptor or receptor material configured to be heated based on induction heating using LGR 110, optionally wherein the second matrix 200b may not include a receptor or receptor material. Additionally, the second aerosol generating matrix 200b may be configured to be heated based on microwave heating using LGR 110. Alternatively or additionally, the first aerosol generating matrix 200a and the second aerosol generating matrix 200b may differ in one or more aspects of humidity level, tobacco type, flavor, and taste.

[0251] The aerosol generating article 202 also includes a mouthpiece 204 and an airflow path 207 and / or an optional filter section 207 configured to deliver aerosol toward the mouthpiece 204 and / or filter the air flowing toward the mouthpiece 204.

[0252] Optionally, the airflow path 207 may include a first flow path portion 207a, which is connected to a first portion 202a of the aerosol generating article 202 and configured to transport the aerosol generated in the first portion 202a toward the mouthpiece 204. Furthermore, the airflow path 207 may include a second flow path portion 207b, which is connected to a second portion 202b of the aerosol generating article 202 and configured to transport the aerosol generated in the second portion 202b toward the mouthpiece 204. The second flow path portion 207b may be connected upstream of the mouthpiece 204 to the first flow path portion 207a, such that the aerosols generated in the first portion 202a and the second portion 202b of the aerosol generating article 202 can mix during transport toward the mouthpiece 204.

[0253] In summary, a consumable or aerosol-generating article 202 in the shape of a key can be provided, allowing the use of matrices 200a, 200b in different portions 202a, 202b of the article. Matrice 200a may include a receptor material and can be configured to be heated by induction heating, while matrix 200b may not include a receptor material and can be configured to be heated based on microwave heating. Portion 202a of article 202 can be inserted into ring 115 of LGR, and portion 202b of article 202 can be inserted into gap 117 of LGR 110. These two separate or different portions 202a, 202b of the aerosol-generating article 202 or the matrix portions 200a, 200b disposed therein can provide different flavors, delivery speeds, etc., which can be adjusted according to individual needs. Optionally, air path or flow path portions 207a, 207b can guide the aerosol generated in article 202 toward mouthpiece 204, where a user can inhale the aerosol.

[0254] Figure 8A and Figure 8B An annular gap resonator 110 is shown in an aerosol generating apparatus 100 or system 500 for generating aerosols. Figure 8A and Figure 8B The annular gap resonator 110 can be used in reference Figures 3 to 7 In either of the described apparatus 100 or system 500. Unless otherwise stated, Figure 8A and Figure 8B The annular gap resonator 110 includes a reference Figures 3 to 7 It has the same characteristics, functions and components as any of the annular gap resonators 110 described in the text.

[0255] Figure 8A and Figure 8B The LGR 110 depicted is a ring-shaped LGR 110. Such a ring-shaped LGR 110 can be obtained by joining the two ends of a tubular or cylindrical LGR 110, for example... Figure 5A and Figure 5B As shown, a closed structure is formed. The magnetic field may be confined within the annular or donut-shaped resonator or ring 115 of the annular LGR 110, and a gap 117 may be formed on its inner or outer periphery and extend along at least a portion of the periphery of the annular ring 115.

[0256] To feed or drive the LGR 110, one or more feed rings 150 may be arranged in the ring 115 or ring portion 115 of the LGR 110. The feed rings 150 may be driven by the power supply circuitry 160 and / or the external power supply device 250 as described above.

[0257] exist Figure 8BThe diagram also shows at least a part or portion of a matrix 200 disposed within a ring 150. The matrix 200 may include a receptor or receptor material and may be configured to be heated by an alternating magnetic field within the ring 115. The matrix material may be solid and / or liquid. In particular, a solid donut-shaped or ring-shaped matrix 200 may be placed within the LGR 110 of its ring 115 to generate an aerosol.

[0258] Alternatively or additionally, substrate 200 or another substrate or substrate portion may be arranged in the gap 117 of LGR 110 and may be configured to be heated by microwave heating, as described with reference to the previous figures. Moreover, such substrate 200 may comprise solid and / or liquid substrate materials, and such substrate may have a substantially annular shape to fit within the gap 117.

[0259] It should also be noted that the toroidal LGR 110 can be used, in particular, as referenced Figure 4 In the aforementioned aerosol generating apparatus 100, such annular LGR 110 may be integrated into a cylinder 130 and used, for example, for heating a liquid matrix, wherein the matrix may be guided toward or through the ring 115 and / or gap 117, for example, by using appropriate conduits or pipes.

[0260] Figures 9A to 9C An aerosol generating apparatus 100 for generating aerosols is shown. Figure 9A A perspective view is shown. Figure 9B and Figure 9C Each shows a cross-sectional view of a different design used for the LGR 110. Unless otherwise stated, Figures 9A to 9C The aerosol generating device 100 includes a reference Figures 3 to 8B The aerosol generating apparatus 100 and system 500 described have the same features, functions and components.

[0261] The aerosol generating apparatus 100 substantially corresponds to or can be considered as an aerosol generating article 202 having an integrated LGR 110. The aerosol generating apparatus 100 includes a matrix 200 or a portion thereof that may be filled with the matrix 200 and may be arranged in a ring 115 of the LGR 110.

[0262] exist Figures 9A to 9C In the example shown, LGR 110 can be formed of a foil of conductive material, which can wrap around the substrate 200 or around a portion of the substrate 200 that can be filled. For example, a foil strip, such as an aluminum foil strip, can be wrapped at least partially around the outer surface of the substrate 200 or around a portion of the device that can be filled with the substrate 200. Alternatively or additionally, the foil strip can be placed inside a paper or insulating package, for example, outside the substrate 200 or the corresponding aerosol generating device 100 or article 204.

[0263] exist Figure 9B In the example shown, the foil only wraps around a portion of the periphery of the substrate 200, thus forming a tubular or cylindrical LGR 110. Figure 9C In the example shown, the foil wraps around the substrate 200, so that in Figure 9B In the example, the portions forming gap 117 overlap along the circumferential direction of LGR 110 and are spaced apart from each other in the transverse direction. Therefore, Figure 9C The LGR 110 shown can be configured as a spiral LGR 110.

[0264] Optionally, at least one delivery ring may also be integrated into the aerosol generating apparatus 100 and / or its corresponding aerosol generating article.

[0265] Figure 10 An aerosol generating apparatus 100 for generating aerosols is shown. Unless otherwise stated, Figure 10 The aerosol generating device 100 includes a reference Figures 3 to 9C The aerosol generating apparatus 100 and system 500 described have the same features, functions and components.

[0266] Similar to Figure 9C The device 100 shown, Figure 10 The aerosol generating apparatus 100 includes a spiral LGR 110 for heating a substrate 200 and generating aerosols. Such a spiral LGR 110 can be formed by arranging a conductive material sheet, such as an aluminum sheet, on one side and paper on the other side, and then wrapping it into a spiral shape. Figure 10 As shown. The substrate 200 can be arranged and heated between the walls of the LGR 110.

[0267] Figure 11 An aerosol generating apparatus 100 for generating aerosols is shown. Unless otherwise stated, Figure 11 The aerosol generating device 100 includes a reference Figures 3 to 10 The aerosol generating apparatus 100 and system 500 described have the same features, functions and components.

[0268] exist Figure 11In the example shown, LGR 110 is a multi-gap LGR 110, exemplarily including four gaps 117a, 117d. Any other number of gaps 117a-d is conceivable. Preferably, the gaps 117a-d may be arranged symmetrically with respect to the central axis or longitudinal axis 111 of LGR 110. This symmetrical arrangement allows for compensation of the electric field effect that each slit or gap 117a-d may generate on other slits or gaps 117a-d. Furthermore, multiple gaps 117a-117d can allow for further confinement of the magnetic field within the ring 115 of LGR 110.

[0269] Using this type of LGR 110, the substrate 200 or a portion thereof can be heated in one or more of the rings 115 and one or more of the gaps 117a-d of the LGR 110. Furthermore, multiple substrates of the same or different types can be used.

[0270] Figure 12 An aerosol generating apparatus 100 for generating aerosols is shown. Unless otherwise stated, Figure 12 The aerosol generating device 100 includes a reference Figures 3 to 11 The aerosol generating apparatus 100 and system 500 described have the same features, functions and components.

[0271] exist Figure 12 In the example shown, LGR 110 is a multi-ring LGR 110, which exemplary includes two rings 115a, 115b and a single gap 117. Any other number of rings 115a, 115b or gap 117 can be contemplated.

[0272] Using this type of LGR 110, the substrate 200 or a portion thereof can be heated in one or more of the rings 115a, 115b and at least one gap 117 of the LGR 110. Furthermore, multiple substrates of the same or different types can be used.
