[0007] The first principal boundary surface of the heated substrate can be planar or substantially planar. The second principal boundary surface of the heated substrate can be planar or substantially planar.

[0008] The first heating device may include multiple first discrete heating sections. For example, the first heating device may include 2, 3, 4, 5, 6, 7, 8, 9, 10 or more first discrete heating sections. The first discrete heating sections may be configured to individually heat different parts of the first aerosol-generated article.

In this exemplary embodiment, it is possible to obtain at least 10 suctions with the same or different aerosols based on a single or multiple types of aerosol forming matrix.

[0010] The first heating device may include 10 first discrete heating sections, and the second heating device may include 10 second discrete heating sections. In this exemplary embodiment, it is possible to obtain at least 20 suctions with the same or different aerosols based on a single or multiple types of aerosol forming matrix.

[0011] The total number of available suction units can be less than the total number of discrete heating portions, for example, when several portions are heated simultaneously to generate a mixed suction. The total number of available suction units can exceed the total number of discrete heating portions, for example, when a portion can be heated more than once to completely clear the aerosol and generate the corresponding aerosol-forming matrix portion of the article.

[0012] Utilizing two chambers and two corresponding heating devices, the aerosol generation apparatus advantageously includes a dual aerosolization system. The dual aerosolization system allows for the loading of two aerosol-generating articles of the same or different types. Based on the operating mode of the apparatus, which selectively powers a desired portion of either aerosol-generating article, the aerosol-generating articles can be consumed independently or simultaneously to provide a desired user experience.

[0013] The aerosol generating apparatus can be configured such that the heating of each of the first and second discrete heating sections is individually controllable. The aerosol generating apparatus can also be configured such that the heating of each of the first and second discrete heating sections is individually controllable according to a separate heating profile. The separate heating profile may include one or more of a separate temperature, a separate heating duration, and a separate temperature ramp.

[0014] An aerosol generating device comprising a separately controllable first and second discrete heating sections allows for a variety of operating modes to achieve one or more of the following: precise quantification, on-demand aspiration, gradual consumption, sequential consumption, and simultaneous consumption of different types of aerosols forming a matrix.

[0015] Each of the first and second discrete heating portions may include a separate sensor element. Each separate sensor element may be configured to be inductively heated.

[0016] The heating substrate can have a layered structure. The layered structure may include a central layer and two outer layers. The central layer may include or be composed of electromagnetic shielding material. Each of the two outer layers may include or be composed of electrically insulating material.

[0017] Electrical insulation materials may comprise one or more of the following: silicone-glass fiber laminates, polyphenylene sulfide (PPS), unfilled PPS, thermosetting cross-linked styrene copolymers, polysulfone, high-density polyolefins such as HDPE (high-density polyethylene), polyethylene terephthalate (PET), canvas-reinforced phenolic resins – NEMA C conforming to MIL-I-24768 TYPE FBM – NEMA CE conforming to MIL-I-24768 TYPE FBG (continuous operating temperature 250℉), polyimide films, polyetheretherketone (PEEK), and composites thereof. Electrical insulation materials may also comprise one or more ceramic materials. The ceramic materials may be based on silica and / or alumina compounds, preferably in the form of monolithic ceramic alumina (aluminum oxide, Al2O3), hot-pressed or directly sintered aluminum nitride (AlN), silicates (including talc and mullite), and silicon carbide (SiC).

[0018] The two outer layers can be arranged to sandwich the central layer between the two outer layers. Discrete heating elements, such as individual sensor elements, can be arranged on the two outer layers.

[0019] Discrete heating elements may contain ferromagnetic stainless steel alloys, such as FDA-grade ferromagnetic stainless steel alloys, such as the SAS304 and 306 series. Discrete heating elements may contain carbon-based materials, such as graphene, graphite, and nanostructures and composites thereof.

[0020] The two outer layers can be a first outer layer and a second outer layer. A first discrete heating element can be arranged on the first outer layer. Individual sensor elements of the first discrete heating element can be arranged on the first outer layer. A second discrete heating element can be arranged on the second outer layer. Individual sensor elements of the second discrete heating element can be arranged on the second outer layer.

[0021] Including electromagnetic shielding material or a central layer made of electromagnetic shielding material can help ensure that the electromagnetic fields and associated currents induced by (multiple) sensors when operating in pairs with corresponding sensor coils remain separate and do not affect (multiple) electromagnetic fields generated by a pair of opposing sensor coils.

[0022] Electromagnetic shielding materials can be materials with EMI shielding properties. Electromagnetic shielding materials can be based on intrinsically conductive polymers and / or conductive polymer composites. Electromagnetic shielding materials may contain one or more of polyacetylene, polythiophene, polypyrrole, polyaniline, and composites thereof. Electromagnetic shielding materials may include portions and / or intermediate layers of insulating polymers having metal and / or carbon-based fillers.

[0023] The first and second discrete heating portions can be attached to the two outer layers by means of an adhesive or deposition method (e.g., electrodeposition) or other suitable means.

[0024] The aerosol generating apparatus may include a separate inductor coil for each individual sensor element. Each individual inductor coil may be configured to inductively heat different sensor elements within the individual sensor element. The inductor coil may be a planar inductor coil. The inductor coil may include one or more copper alloys.

[0025] The aerosol generating apparatus can be configured such that when a first aerosol generating article is inserted into a first cavity, the first aerosol generating article is sandwiched between a heating substrate and a sensor coil of a sensor element for heating a first discrete heating portion. The aerosol generating apparatus can also be configured such that when a second aerosol generating article is inserted into a second cavity, the second aerosol generating article is sandwiched between a heating substrate and a sensor coil of a sensor element for heating a second discrete heating portion.

[0026] The aerosol generating apparatus may include a first sliding tray for holding a first aerosol-generated article. The aerosol generating apparatus may also include a second sliding tray for holding a second aerosol-generated article.

[0027] The first and second sliding trays can be arranged on opposite sides of the aerosol generating device.

[0028] The first sliding tray may include a first frame structure for holding the first aerosol-generated article. The second sliding tray may include a second frame structure for holding the second aerosol-generated article.

[0029] The first frame structure and the second frame structure can be one or both of different shapes and sizes to prevent the insertion of erroneous aerosol-generated articles in accordance with the key-lock principle.

[0030] One or both of the first frame structure and the second frame structure may include positioning corner portions. This prevents the insertion of aerosol-generated articles with corresponding positioning corner portions in the wrong orientation.

[0031] The positioning corners within the tray frame structure and the aerosol-generating article ensure that the aerosol-generating article is always correctly positioned within the frame structure. This guarantees that the aerosol-generating article is always correctly positioned within the tray for proper use.

[0032] One or both of the first and second frame structures may include sealing elements. The sealing elements of the frame structures may be configured to engage with corresponding sealing elements of the heating substrate when the respective sliding tray is closed to provide a seal to the respective cavity.

[0033] One or both of the first frame structure and the second frame structure, as well as the sealing element of the heating substrate, may comprise an elastic material, more preferably an elastomeric material, and even more preferably a material selected from one or more of the following: synthetic rubber, thermoplastic elastomers (TPE), styrene-based materials, thermoplastic polyolefins (TPO), LDPE, HDPE, LLDPE, ULDPE, silicone rubber, polyurethane, PDM, thermoplastic elastomers, and composites thereof.

[0034] The first cavity may form part of a first slidable tray. The second cavity may form part of a second slidable tray. Once the respective first or second slidable tray is inserted into the device together with the respective first or second aerosol generating article, the first and second cavities can be used as heating chambers for heating the respective first or second aerosol generating article received therein.

[0035] The aerosol generating apparatus can be configured such that the insertion direction of each of the first and second sliding trays is inclined relative to the first and second main boundary surfaces of the heated substrate. The aerosol generating apparatus can be configured such that the insertion direction of each of the first and second sliding trays is inclined relative to the first and second main boundary surfaces of the heated substrate at an angle between 1 and 10 degrees, more preferably between 2 and 7 degrees, and even more preferably between 2 and 5 degrees.

[0036] The inclined insertion direction of the first and second sliding trays relative to the planar primary boundary surfaces of the heating substrate causes each of the first and second sliding trays to move diagonally relative to the planar surface of the heating substrate. This diagonal movement converts the force applied to close the trays into a gradually applied vertical force on the overall planar primary boundary surface of the heating substrate, which is maintained when the trays remain fully closed. This vertical force presses the trays against the corresponding surfaces of the heating substrate. The inclined insertion direction ensures close contact between the aerosol-forming article and the corresponding heated portions of the first and second primary boundary surfaces of the heating substrate when the trays are closed. The inclined insertion direction improves the efficiency of heat transfer from the heated portions to the aerosol-forming matrix. The inclined insertion direction also improves the targeted heating of specific discrete aerosol-forming matrix portions by specific discrete heated portions. Finally, the inclined insertion direction provides an airtight seal for both the first and second cavities.

The aerosol generating apparatus may also include a second button configured to open a second sliding tray.

The second retaining device may interlock with the first button such that when the second slidable tray is open, the first button is locked, and when the second slidable tray is closed, the first button is operable to open the first slidable tray.

[0041] The tray locking mechanism may include a gravity-sensitive element. The gravity-sensitive element may include a first configuration and a second configuration.

[0098] An aerosol-generating article comprising multiple discrete aerosol-forming matrix portions can be configured such that, when the article is inserted into a device, the discrete aerosol-forming matrix portions geometrically coincide with the positions of corresponding first or second discrete heating portions of the heating substrate. This allows for individual control of the heating of each individual discrete aerosol-forming matrix portion. Thus, it is possible to enable various different usage modes by heating the discrete aerosol-forming matrix portions individually, on demand, sequentially, or simultaneously.

[0099] The aerosol generating apparatus and system of the present invention allow for the loading of two aerosol generating articles of the same or different types, and their independent or simultaneous use. The aerosol generating apparatus and system of the present invention allow for the portioning of the aerosol generating articles with accurate aerosol content corresponding to the volume of the sensory portion of the aerosol forming matrix or half of it (in the case that each aerosol forming matrix portion of either of the two aerosol generating articles loaded within the apparatus corresponds to two separate heating portions). The aerosol generating apparatus and system of the present invention allow for independent heating of the aerosol forming matrix portion. Independent and / or different temperature profiles can be provided at any time. Independent temperature profiles can be configured to match different aerosolization conditions of different aerosol forming matrices of different aerosol forming matrix portions. Heating can be controlled independently and at any time, thereby allowing segmented heating according to an on-demand suction mode, or in any order and combination selected by the user according to his or her preferences, or, for example, by gradual sequential heating in a predefined consumption order.

[0100] Each of the first heating device and the second heating device may include one or more heating elements. Each of the first discrete heating portion and the second discrete heating portion may be configured as a separate heating element. The heating element may be any kind of heating element as described herein, or may be part of it.

[0101] The heating element can be a dielectric or capacitive heating element. For example, a dielectric or capacitive heating element having two or more flat or planar electrodes arranged to removably receive an exemplary flat or planar aerosol generation article therebetween, interconnected to an AC source via an impedance matching circuit, can be used to generate microwaves between the electrodes for capacitive / dielectric heating.

[0102] The heating element can be a resistance or Joule-type heating element, such as an aerosol forming apparatus, an exemplary flat or planar aerosol forming article, or a combination thereof. The resistance heating element can take any suitable form. For example, the resistance heating element can take the form of one or more flexible heating foils on a dielectric substrate (such as polyimide). The flexible heating foil can be shaped to conform to the periphery of the corresponding cavity. Alternatively, the resistance heating element can take the form of one or more metal grids, flexible printed circuit boards, molded interconnect devices (MIDs), ceramic heaters, flexible carbon fiber heaters, or can be formed on a suitable shaped substrate using coating techniques such as plasma vapor deposition. The resistance heating element can also be formed using a metal having a defined relationship between temperature and resistivity. In such an exemplary device, the metal can be formed as a track between two layers of suitable insulating material. Resistance heating elements formed in this way can be used to both heat the resistance heating element and monitor its temperature during operation. It is also possible that the resistance heating element is part of an aerosol forming article, which is, for example, a flat or planar aerosol forming article, such as, but not limited to, a plate-like shape or having resistance tracks arranged on a flat heater substrate, as described in WO2016 / 005530 and WO2016 / 005533, which show a cylinder with an integrated heating element, and these references are incorporated herein by reference in their entirety.

[0103] The heating element can be a radiation-based heating element, such as, but not limited to, a semiconductor-based heating element having an array of separate radiation-based heating elements, as shown in, for example, WO2017 / 182249, which is incorporated herein by reference in its entirety.

[0104] Radiation-based heating elements can be non-contact heaters, such as those shown in WO2022 / 207447, which is incorporated herein by reference in its entirety.

[0105] Radiation-based heating elements may include a radiation source that can radiate onto the surface or layer of a flat aerosol-formed article to induce aerosolization or evaporation. The radiation source may be configured to emit electromagnetic radiation. This electromagnetic radiation may be microwave, far-infrared, infrared, near-infrared, or visible light.

[0106] The radiation source can be a photonic device or a laser irradiation device. The photonic device can be a light-emitting diode (LED). The radiation source can be a perovskite LED.

[0107] The photonic device can be a thin film that emits electromagnetic radiation, preferably infrared radiation.

[0108] The radiation source may include an infrared radiation coating, such as a NiCr2O4 powder coating or other high emissivity ceramic coating that can emit infrared light.

[0109] The heating element may be an induction heating element. An induction heating element may include one or more induction coils, each induction coil surrounding a corresponding cavity. For example, a helical induction coil may extend around a first and second main boundary surface of the cavity. The longitudinal axis of said or each induction coil may be substantially parallel to the main flow axis. For example, the heating element may be configured to have planar coils configured for inductively heating internal, external, or contacting flattened receptors within the aerosol-forming matrix of a flat or planar aerosol-forming article, as described, for example, in WO2015 / 177043 or WO2015 / 177044, which are incorporated herein by reference in their entirety.

[0110] As used in this article, the term "longitudinal axis" for induction coils refers to an axis that extends through the center of the coil in a direction generally perpendicular to the turns of the coil.

[0111] The induction heating element may be arranged as an induction heating sensor. The induction heating element may include one or more induction coils positioned adjacent to the first and / or second main boundary surfaces of the respective cavity. The longitudinal axis of said or each induction coil may be substantially perpendicular to the main flow axis, for example, perpendicular to the plane defined by the first main boundary surface.

[0112] One or more induction coils may be planar. For example, a planar induction coil may be positioned adjacent to and parallel to one of the first and second main boundary surfaces of the corresponding cavity. For example, a first planar induction coil may be positioned adjacent to and parallel to the first main boundary surface, and a second planar induction coil may be positioned adjacent to and parallel to the second main boundary surface.

[0113] The receptor may be part of the aerosol-generating article within the cavity. The receptor may be part of the aerosol-generating apparatus. For example, the receptor may be disposed on the inner side of the cavity. For example, one or both of the first and second main boundary surfaces of the corresponding cavity may contain receptor material.

[0114] In use, the sensor can be inductively heated by the aforementioned or each induction coil. The sensor then conductively, convectively, and / or radiatively heats the aerosol-forming matrix located near the sensor.

[0115] A "sensor" is an element that heats up when subjected to a changing or alternating magnetic field. Typically, a sensor is conductive, and the heating of the sensor is a result of eddy currents or hysteresis losses induced within it. Both hysteresis losses and eddy currents can occur in a sensor. Sensors can include graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, and any other conductive material. Preferably, the sensor element is a ferrite element. The material and geometry of the sensor can be selected to provide the desired resistance and heat generation.

[0116] In the operation of an induction heater, a high-frequency alternating current passes through one or more induction coils to generate one or more corresponding alternating magnetic fields. These alternating magnetic fields induce a voltage in the sensor of the workpiece. The induced voltage causes a current to flow in the sensor, and this current causes Joule heating of the sensor, which in turn heats the aerosol forming the matrix. If the sensor is ferromagnetic, hysteresis losses in the sensor can also generate heat.

[0117] The term “high frequency” refers to frequencies ranging from about 500 kHz (KHz) to about 30 MHz (MHz) (including the range from 500 kHz to 30 MHz), particularly from about 1 MHz (MHz) to about 10 MHz (including the range from 1 MHz to 10 MHz), and even more particularly from about 5 MHz (MHz) to about 7 MHz (MHz) (including the range from 5 MHz to 7 MHz).

[0118] Throughout this disclosure, the term "magnetic field" may refer to a changing or alternating magnetic field.

[0119] Throughout this disclosure, the term "current" may refer to alternating current.

[0120] The heating element may be configured or can be configured to heat the article received in the cavity to a temperature below 400 degrees Celsius, for example below 300 degrees Celsius, such as below 270 degrees Celsius. In some embodiments, the heater may be configured or can be configured to heat the article received in the heating chamber for forming an aerosol to a temperature below 250, 225, 200, 175, or 150 degrees Celsius, for example below 140, 130, 120, 110, 100, or 90 degrees Celsius.

[0121] The aerosol generating apparatus may include a power source or power supply device, typically a battery, located within the main body of the aerosol generating apparatus. In one embodiment, the power supply device is a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery such as a lithium-cobalt, lithium-iron-phosphate, lithium titanate, or lithium-polymer battery. Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity sufficient to store enough energy for one or more uses; for example, the power source may have sufficient capacity to continuously generate aerosols for periods of approximately six minutes or multiples of six minutes. In another instance, the power supply device may have sufficient capacity to provide intermittent activation of the suction or heating element for a predetermined number of times.

[0239] Figure 1 An aerosol generation system, including an aerosol generating apparatus, is schematically shown in cross-sectional view. The aerosol generating apparatus includes a first chamber 10 for receiving a first aerosol generating article 12. The aerosol generating apparatus also includes a second chamber 20 for receiving a second aerosol generating article 22. The aerosol generation system includes the aerosol generating apparatus and one or both of the first aerosol generating article 12 and the second aerosol generating article 22.

[0240] The aerosol generating apparatus includes a heating substrate 30 spatially disposed between a first cavity 10 and a second cavity 20. The heating substrate 30 includes a first main boundary surface 40 facing the first cavity 10. The heating substrate 30 includes a second main boundary surface 50 opposite to the first main boundary surface 40 and facing the second cavity 20. The first main boundary surface 40 includes a first heating device for heating the first aerosol generating article 12 when it is received in the first cavity 10. The second main boundary surface 50 includes a second heating device for heating the second aerosol generating article 22 when it is received in the second cavity 20.

[0241] The aerosol generating apparatus includes an airflow path extending from at least one air inlet located at the distal end of the apparatus, through a first cavity 10 and a second cavity 20, to at least one air outlet 64 located at the proximal end of the apparatus. The first cavity 10 and the second cavity 20 are arranged parallel to each other in the airflow path. The at least one air inlet may include a first air inlet 60 fluidly connected to the first cavity 10 and a second air inlet 62 fluidly connected to the second cavity 20. The apparatus includes a longitudinal central axis 100 extending between the distal and proximal ends of the apparatus.

[0242] The first chamber 10 and the second chamber 20 may be structurally identical or structurally similar. Heating of the first chamber 10 and the second chamber 20 by means of corresponding first and second heating devices can be individually controlled by the common control unit of the apparatus. Therefore, the apparatus can be considered as representing an aerosol generating apparatus with dual heaters for heating two articles. The airflow through the first chamber 10 and the second chamber 20 can be individually controlled by the common control unit of the apparatus.

[0243] Figure 2 The heating substrate 30 is shown in perspective views from a to 2c. Figure 2 The heating substrate shown in a to 2c can, for example, be in Figure 1 It is used in aerosol generating devices.

[0244] Figure 2 The heated substrate 30 is shown in an exploded view.

[0245] The first heating device arranged on the first main boundary surface 40 includes a plurality of first discrete heating portions 42 for individually heating different portions of the first aerosol-generating article 12. The second heating device arranged on the second main boundary surface 50 includes a plurality of second discrete heating portions 52 for individually heating different portions of the second aerosol-generating article 22. The aerosol generating device is preferably configured such that the heating of each of the first discrete heating portions 42 and the second discrete heating portions 52 is individually controllable.

[0246] Each of the first discrete heating portion 42 and the second discrete heating portion 52 may include individual sensor elements 42, 52 configured to be inductively heated. Preferably, for each individual sensor element 42, 52, the aerosol generating apparatus includes a separate sensor coil, preferably a separate planar sensor coil, configured to inductively heat the corresponding sensor element 42, 52.

[0247] Figure 2The heating substrate 30 of a has a layered structure. The layered structure includes a central layer 32 of electromagnetic shielding material and two outer layers 44 and 54 of electrical insulation material. The two outer layers 44 and 54 are arranged to sandwich the central layer 32 between the two outer layers 44 and 54. Separate heating elements 42 and 52 are arranged on the two outer layers 44 and 54.

[0248] The dashed line on layer 54 indicates that the second discrete heating portion 52 is located on the bottom side of layer 54, and therefore... Figure 2 It is not visible in the perspective view of a.

[0249] Figure 2 b shows the assembly configuration. Figure 2 a is a heating substrate 30.

[0250] Figure 2 c shows the relationship with Figure 2 The heating substrates of a and 2b are similar to heating substrate 30. Unlike... Figure 2 Heating substrates for a and 2b Figure 2 The heating substrate 30 of c includes a sealing element 34 surrounding the periphery of the two outer layers 44, 54. Further different from... Figure 2 Heating substrate 30 for a and 2b Figure 2 The heating substrate 30 of c includes a bridging element 36 for mounting the heating substrate 30 within the aerosol generating apparatus.

[0251] Figure 3 a and 3b exemplarily illustrate the interaction between a heated substrate 30 and a first aerosol generating article 12 during use of the aerosol generating system. The first aerosol generating article 12 can be brought to a first primary boundary surface 40 adjacent to the heated substrate 30, which includes an outer layer 44 having a plurality of first discrete heating portions 42. The first aerosol generating article 12 includes a primary boundary surface 14. The aerosol generating article 12 may have positioning corners 15 for preventing its incorrectly oriented insertion.

[0252] The main boundary surface 14 of the first aerosol-generating article 12 includes multiple discrete aerosol-forming matrix portions 16. For example... Figure 3As indicated in b, when the first aerosol generating article 12 is inserted into the first cavity 10, each of the first discrete heating portions 42 is covered with one of the discrete aerosol forming matrix portions 16 of the first aerosol generating article 12. The plurality of first discrete heating portions 42 are configured to individually heat the discrete aerosol forming matrix portions 16 of the first aerosol generating article 12. Each discrete heating portion 42 is dedicated to one of the discrete aerosol forming matrix portions 16. Every two discrete heating portions 42 can be dedicated to each of the discrete aerosol forming matrix portions 16. This allows for the gradual consumption of individual discrete aerosol forming matrix portions 16, or allows consumption in one step when two discrete heating portions 42 dedicated to one discrete aerosol forming matrix portion are heated simultaneously.

[0253] like Figure 1 As indicated in the document, the second aerosol-generating product ( Figure 3 (not shown in a and 3c) can be constructed similarly to the first aerosol generating article 12 and can be located on the underside of the heating substrate 30 during use, such that the heating substrate 30 is sandwiched between the first aerosol generating article 12 and the second aerosol generating article 22.

[0254] The discrete heating sections 42 and 52 can be individual sensor elements. When the aerosol generating articles 12 and 22 are properly placed in the cavities 10 and 20, the aerosol generating articles are geometrically and dimensionally matched to the matrix of heating sections on the surface of the heating substrate 30. Thus, the aerosol forming matrix portion coincides with and is proportional in size to the sensor element, which can be designed to operate in pairs with a corresponding sensor coil. Once the sensor coil is powered, managed by the control unit of the aerosol generating apparatus according to the operating mode, one or more sensor elements will heat up, generating a temperature that is transferred to the corresponding aerosol forming matrix portion, thereby generating a specific aerosol. Each sensor coil can be powered and managed independently, and thus a specific temperature profile is generated in the corresponding sensor element, which heats the specific aerosol forming matrix portion to generate an aerosol.

[0255] Figure 4 A cross-sectional view of an aerosol generating apparatus is shown. The aerosol generating apparatus includes components for receiving a first aerosol-generating product and a second aerosol-generating product. Figure 4 A first cavity 10 and a second cavity 20 (not shown in the diagram). A heating substrate 30 is spatially arranged between the first cavity 10 and the second cavity 20. The heating substrate 30 can be as follows: Figure 2The heating substrate 30 shown in a to 2c includes a first discrete heating portion 42 and a second discrete heating portion 52 on opposite sides thereon. The aerosol generating apparatus includes an airflow path extending from two air inlets 60, 62 through a first chamber 10 and a second chamber 20 to an air outlet 64.

[0256] The first chamber 10 and the second chamber 20 are arranged in parallel in the airflow path. A first branch of the airflow path extends from the first air inlet 60 to the first chamber 10 along a first upstream portion 66, and then extends to the mixing chamber 74 along a first downstream portion 70. A second branch of the airflow path extends from the second air inlet 62 to the second chamber 20 along a second upstream portion 68, and then extends to the mixing chamber 74 along a second downstream portion 72. Thus, the first and second branches of the airflow path are arranged side by side and merge in the mixing chamber 74. The mixing chamber can function as either a homogenization chamber or a cooling chamber, or both.

[0257] The first upstream portion 66 includes a first valve device 76 for controlling the airflow through the first chamber 10. The second upstream portion 68 includes a second valve device 78 for controlling the airflow through the second chamber 20. Preferably, the first valve device 76 and the second valve device 78 are airflow electronic valves.

[0258] The total suction resistance (RTD) of the aerosol generation device, as perceived by the user, can be managed by the control unit 90 of the aerosol generation device. The control unit 90 can be configured to power and control the airflow electronic valves 76, 78. These electronic valves can be defined and designed to provide the total RTD value when operating individually, and half of the total RTD when both aerosolization chambers 10, 20 are operating simultaneously. In this way, the total RTD perceived by the user at the air outlet 64 can remain consistent and stable throughout all user experiences, regardless of whether one or both of the first chamber 10 and the second chamber 20 actively generate aerosols, which are homogenized and cooled in chamber 74 before inhalation. Such RTD at the final aerosolization outlet 64 can be approximately 20 to 220 mmH2O, preferably approximately 70 to 140 mmH2O.

[0259] The aerosol generating device includes a nozzle 80 at its proximal end. A mixing chamber 74 and an air outlet 64 are arranged in the nozzle 80.

[0260] For each individual sensor element of the first discrete heating section 42, the aerosol generating device includes a first individual sensor coil 43 configured to inductively heat the corresponding sensor element. For each individual sensor element of the second discrete heating section 52, the aerosol generating device includes a second individual sensor coil 53 configured to inductively heat the corresponding sensor element. Preferably, the sensor coils 43 and 53 are planar sensor coils. Figure 4 In the embodiment shown, there are five first discrete heating portions 42 and five second discrete heating portions 52 arranged along the longitudinal axis of the device, such that there are a total of ten individual inductor coils 43, 53.

[0261] The aerosol generating apparatus is configured such that when the first aerosol generating article ( Figure 4 When the first aerosol generating article (not shown) is inserted into the first cavity 10, it is sandwiched between the heating substrate 30 and the first sensor coil 43 for heating the sensor element of the first discrete heating portion 42, and when the second aerosol generating article ( Figure 4 When the second aerosol generating article (not shown) is inserted into the second cavity 20, it is sandwiched between the heating substrate 30 and the second sensor coil 53 for heating the sensor element of the second discrete heating section 52.

[0262] The aerosol generating apparatus includes a first operation display 82 and a second operation display 84. The first operation display 82 and the second operation display 84 are arranged on opposite sides of the aerosol generating apparatus. The first operation display 82 is configured to provide information regarding the operational status of a first aerosol-generated article received in the first chamber 10. The second operation display 84 is configured to provide information regarding the operational status of a second aerosol-generated article received in the second chamber 20.

[0263] The aerosol generating device includes a first battery 86. The first battery 86 is configured to power a first sensor coil 43. The aerosol generating device also includes a second battery 88. The second battery 88 is configured to power a second sensor coil 53.

[0264] The aerosol generating apparatus may include a magnetic shielding material layer disposed between the first sensor coil 43 and the first battery 86. The aerosol generating apparatus may also include a magnetic shielding material layer disposed between the second sensor coil 53 and the second battery 88.

[0265] The aerosol generating device may include a charging and data port 92 electrically connected to the control unit 90.

[0266] Each of the first discrete heating section 42 and the second discrete heating section 52 can be individually controllable. Thus, the aerosol generating device can operate in different heating modes, wherein different discrete heating sections of the first discrete heating section 42 and the second discrete heating section 52 are activated. This is in Figure 5 Examples are shown in a and 5b.

[0267] Figure 5 Figures a and 5b show cross-sectional views of subsections of the aerosol generation system under different heating modes. Figure 5 The upper parts of a and 5b are shown as follows: Figure 4 The diagram shows a side view rotated 90 degrees clockwise. The lower portion shows a top view rotated 90 degrees along the longitudinal axis. The upper portion shows section AA, as indicated by the arrow in the lower portion and denoted by "A".

[0268] Figure 5 The aerosol generating devices of systems a and 5b are very similar Figure 4 The device, in addition to Figure 5 The devices a and 5b include separate first and second mixing chambers arranged in parallel in the first and second downstream portions of a first branch and a second branch in the airflow path, as if by means of... Figure 5 The first mixing chamber 73, as indicated by the sub-sections of the devices a and 5b, is visible. Figure 5 a and 5b show only a sub-section of the aerosol generating device, focusing on the first branch and the first cavity 10, which has its five first discrete heating sections 42a to 42e and its five first individual inductor coils 43a-43e. However, the second branch and the second cavity 20 include a similar mirror arrangement.

[0269] exist Figure 5 In each of a and 5b, a first aerosol generating article 12 comprising five discrete aerosol forming matrix portions 16a to 16e disposed on its main boundary surface 14 is received in the first cavity 10. The five aerosol forming matrix portions 16a to 16e may comprise the same composition of the aerosol forming matrix, such as that made from... Figure 5 The common contrast of the portions in a may indicate, or may include, different compositions of the aerosol-forming matrix, such as those derived from... Figure 5 The different contrasts in part b are exemplarily indicated.

[0270] Figure 5a illustrates a first heating mode in which only one of the first individual inductor coils 43a to 43e, inductor coil 43c, operates to heat the corresponding inductor element of the discrete heating portion 42c. Only one of the five discrete aerosol forming matrix portions 16a to 16e, corresponding to a discrete aerosol forming matrix portion 16c, is subsequently heated to generate an aerosol.

[0271] Figure 5 b illustrates a second heating mode in which two of the first individual inductor coils 43a and 43c, respectively, operate to heat corresponding inductor elements of discrete heating portions 42a and 42c. Two corresponding discrete aerosol forming matrix portions 16a and 16c of the five discrete aerosol forming matrix portions 16a to 16e are then heated to generate aerosols. The evaporation components of the two portions 16a and 16e can be mixed in the first mixing chamber 73.

[0272] The system can operate in various other operating and heating modes, allowing for many different combinations, wherein one or more of the first discrete heating section 42 and / or the second discrete heating section 52 can be activated. Simultaneous and / or sequential activation is possible. Aerosol generating apparatuses can be provided that allow for many different operating and heating modes, depending on user preference and / or on the type of aerosol generated article used.

[0273] Because of the individually controllable discrete heating components and corresponding aerosol forming matrix components, consistent and repeatable consumption and user experience can be provided.

[0274] In addition to allowing for consistent and repeatable consumption and a superior user experience, the device also enables a high level of customization. Users can always select a fully customizable specific operating mode, making it possible to inhale specific aerosols generated at any time from a specific portion of the aerosol-forming matrix included in the aerosol-generating article, and to create combinations and sequences of aerosols as needed. This is a unique and differentiating benefit and feature of the device, allowing for optimal performance of the article's properties.

[0275] As previously explained, the aerosol generating device of the present invention can achieve optimal performance of the characteristics of an aerosol-generating article having multiple parts of an aerosol-forming matrix. This can be particularly beneficial for applications requiring accurate dosing for inhalation (e.g., according to a medical prescription for a specific drug to be inhaled). Therefore, the aerosol generating device can be suitable for applications in the life sciences or medical delivery device fields where accurate controlled dosing of aerosolization may be mandatory.

[0276] In practice, such requirements for accurate total aerosolization (e.g., quantification) of each aerosol-forming matrix portion can be achieved using the aforementioned aerosol-generating articles used in the aerosol-generating apparatus disclosed herein. Any aerosolization can be generated independently with high precision, including total aerosolization ensuring a specific volume of aerosol present in each aerosol-forming matrix portion. Thus, the apparatus can operate to perform aerosolization of an aerosol-forming matrix that meets the requirements of life sciences and delivery devices, the aerosol-forming matrix comprising active substances containing drugs that can be ingested by inhalation or preferably by inhalation, as well as active substances in the health field, including aerosols generated from plant-derived materials.

[0277] For example, in using with Figure 5 In the case of an aerosol-generating article with the same discrete aerosol-forming matrix portion, accurate aerosolization can be achieved based on the precise volume of each portion supplied individually for inhalation driven by the user's suction. This is an ideal scenario for users who need to inhale medication regularly every day and frequently throughout the day. The device meets these requirements while being very compact and portable, thus ensuring multi-dose delivery for daily or weekly intake.

[0278] For example, in using with Figure 5 In the case of one or two aerosol-generated articles formed by different discrete aerosols forming matrix parts in b, the user can choose from various combinations of different types of aerosols according to the user's preference, depending on the combination of the selected heated discrete parts.

[0279] Figure 6 a to 6c show aerosol generating apparatuses, such as the aerosol generating apparatus in any of the aforementioned figures.

[0280] Figure 6 a and 6b show the aerosol generating apparatus along six different viewing directions. Figure 6 a shows four viewing directions perpendicular to the longitudinal central axis 100, each viewing direction being rotated 90 degrees sequentially from top to bottom along the longitudinal central axis 100.

[0281] The first main boundary surface of the aerosol generating device includes a first operation display 82. The first main boundary surface also includes a first button 94.

[0282] The second main boundary surface of the aerosol generating device includes a second operation display 84. The second main boundary surface also includes a second button 96. The second main boundary surface is opposite to the first main boundary surface. The first button 94 and the second button 96 are arranged on opposite sides of the aerosol generating device. The first operation display 82 and the second operation display 84 are also arranged on opposite sides of the aerosol generating device.

[0283] The first operation display 82 is configured to provide information about the operating status of the first aerosol generating article 12 when it is received in the first cavity 10. The second operation display 84 is configured to provide information about the operating status of the second aerosol generating article 22 when it is received in the second cavity 20.

[0284] The first boundary surface of the aerosol generating apparatus includes a first insertion device for inserting a first aerosol generating article 12 into a first cavity 10. The first insertion device is configured to hold a first slidable tray 11 for holding the first aerosol generating article 12.

[0285] The second boundary surface of the aerosol generating apparatus includes a second insertion device for inserting the second aerosol generating article 22 into the second cavity 20. The second insertion device is configured to hold a second slidable tray 21 for holding the second aerosol generating article 22.

[0286] The first sliding tray 11 and the second sliding tray 21 are arranged on opposite sides of the aerosol generating device.

[0287] The first sliding tray 11 and the second sliding tray 21 can be arranged symmetrically with respect to the longitudinal central axis 100, such that the longitudinal central axis is a double rotation axis with respect to the first sliding tray 11 and the second sliding tray 21.

[0288] The first button 94 is configured to open the first sliding tray 11. The second button 96 is configured to open the second sliding tray 21.

[0289] The aerosol generating apparatus may include a tray locking mechanism. The tray locking mechanism is configured to lock one of a first sliding tray 11 and a second sliding tray 21 at a time. The tray locking mechanism is configured to prevent the second sliding tray 21 from opening when the first sliding tray 11 is open. The tray locking mechanism is configured to allow the second sliding tray 21 to open when the first sliding tray 11 is closed. The tray locking mechanism is configured to prevent the first sliding tray 11 from opening when the second sliding tray 21 is open. The tray locking mechanism is configured to allow the first sliding tray 11 to open when the second sliding tray 21 is closed.

[0290] The tray locking mechanism includes a first retaining device for holding a first slidable tray 11 in a closed position and a second retaining device for holding a second slidable tray 21 in a closed position. The first retaining device is interlocked with a second button 96 such that when the first slidable tray 11 is open, the second button 96 is locked, and when the first slidable tray 11 is closed, the second button 96 is operable to open the second slidable tray 21. The second retaining device is interlocked with a first button 94 such that when the second slidable tray 21 is open, the first button 94 is locked, and when the second slidable tray 21 is closed, the first button 94 is operable to open the first slidable tray 11.

[0291] The tray locking mechanism may include a gravity-sensitive element comprising a first configuration and a second configuration. The gravity-sensitive element is configured to switch between the first and second configurations depending on the orientation of the aerosol generating device relative to a center of gravity. The tray locking mechanism is configured to lock a first slidable tray 11 when the gravity-sensitive element is in the first configuration, and to lock a second slidable tray when the gravity-sensitive element is in the second configuration. The gravity-sensitive element is configured in the first configuration when the aerosol generating device is oriented relative to a center of gravity such that the second slidable tray 21 is spatially located between the first slidable tray 11 and the center of gravity. The gravity-sensitive element is configured in the second configuration when the aerosol generating device is oriented relative to a center of gravity such that the first slidable tray 11 is spatially located between the second slidable tray 21 and the center of gravity.

[0292] The second sliding tray 21 may be spatially located between the first sliding tray 11 and the first main boundary surface of the aerosol generating device, including the first operation display 82. The first sliding tray 11 may be spatially located between the second sliding tray 21 and the second main boundary surface of the aerosol generating device, including the second operation display 84.

[0293] For example, when the aerosol generating device is placed on a table, the first sliding tray 11 is operable when the first main boundary surface, including the first operation display 82, is at the top, and the second sliding tray 21 is operable when the second main boundary surface, including the second operation display 84, is at the top. "At the top" means facing upwards, away from the center of gravity, and visible to the user. This improves the usability of the device. For example, it prevents the user from accidentally opening the wrong tray. For instance, opening an inverted tray could cause the aerosol-generated product to accidentally fall out. If the user wants to load both trays 11 and 21, they can do so one after the other by loading one tray and then rotating the device 180 degrees to load the other tray.

[0294] Figure 6b shows two viewing directions along the longitudinal central axis 100. Figure 6 The left side of b shows a view of the near end of the device, making the air outlet 64 at the mouthpiece 80 visible. Figure 6 The right side of b shows a view of the far end of the device, making air inlets 60, 62 and charging and data ports 92 visible.

[0295] Figure 6 c illustrates an example of a technical configuration of the device that allows for a comfortable and user-friendly user experience using operation displays 82, 84. For example, by means of the first operation display 82, a user can be informed of the remaining amount of each of the first discrete aerosol forming matrix portions 16a to 16e of the first aerosol generating article 12 via indicator bars 82a to 82e. For example, operation displays 82, 84 may be OLED displays or any other suitable displays known to those skilled in the art.

[0296] Therefore, the aerosol generating apparatus may include two independent operating displays 82, 84 that interface with each of the first and second heating devices. Thus, the apparatus can be operable to display a visual indication of the exact consumption of each of the two aerosol generating articles 12, 22. The apparatus can also be operable to display a visual indication of the exact consumption of each sub-section of the two aerosol generating articles. This can be achieved by a control unit configured to independently power each of the first discrete heating section 42 and the second discrete heating section 52. The control unit may store information about which of the heating sections 42, 52 has been activated for a given aerosol generating article 12, 22, and can therefore indicate which portions of the aerosol forming matrix have been consumed, or are in the process of being consumed.

[0297] Figure 7 The first sliding tray 11 with an opening is shown along five different viewing directions. Figure 6 The aerosol generating apparatus includes a first slidable tray 11 with a first frame structure 112 for holding a first aerosol generating article 12. The first frame structure 112 includes positioning corner portions 114. This prevents incorrect insertion of the aerosol generating article 12 with corresponding positioning corner portions 15. The first frame structure 112 includes a sealing element 116 configured to engage with a corresponding sealing element 34 of the heating substrate 30 when the first slidable tray 11 is closed, to provide a seal to the first cavity 10.

[0298] Figure 8 The first sliding tray 11 and the second sliding tray 21, both with open, are shown along three different viewing directions. Figure 6 Aerosol generating device. Figure 8The configuration shown is for illustrative purposes only, to emphasize the double rotational symmetry of the aerosol generating device relative to the first sliding tray 11 and the second sliding tray 21 about the longitudinal central axis 100. However, in the case where the device includes a tray locking mechanism, it is practically impossible for the user to open both the first sliding tray 11 and the second sliding tray 21 simultaneously.

[0299] Figure 8 The second sliding tray 21 is shown to be structurally similar to the first sliding tray 11 and includes a second frame structure 122 for holding the second aerosol-generating article 22. The second frame structure 122 includes positioning corner portions 124. The positioning corner portions 114, 124 of the first frame structure 112 and the second frame structure 122 may be structurally identical. The positioning corner portions 114, 124 of the first frame structure 112 and the second frame structure 122 may be structurally different to prevent the first aerosol-generating article 12 from being inserted into the second frame structure 122, and vice versa.

[0300] The second frame structure 122 includes a sealing element 126 configured to engage with a corresponding sealing element 34 of the heating substrate 30 when the second sliding tray 21 is closed, to provide a seal to the second cavity 20.

[0301] Figure 9 Examples a to 9c illustrate inserting the first aerosol generating article 12 into Figure 8 In the aerosol generation device. Figure 9 The devices in b and 9c are along Figure 8 The cross-sectional view of line AA shown in the figure is now in the closed position, however, the second sliding tray 21 is now in the closed position.

[0302] Figure 9 a shows a first aerosol-generating article 12, whose main boundary surface 14 has positioning corners 15. Dashed lines indicate that the discrete aerosol-forming matrix portion 16 is located on the back side.

[0303] Figure 9 b shows a first aerosol-generating article 12 then positioned on top of an open first sliding tray 11 (where the discrete aerosol-forming matrix portion 16 of the article points toward the center of gravity), such that the positioning corner 15 of the article 12 matches the positioning corner 114 of the first frame structure 112 of the first sliding tray 11.

[0304] Then, as Figure 9 As shown in Figure c, the first aerosol generating article 12 can be received in the first frame structure 112 of the first sliding tray 11. Figure 9 The arrow in c indicates how the first sliding tray 11 can then be closed along the closing direction 132.

[0305] This can also be done Figure 9 As seen in b and 9c, the first individual sensor coil 43 is part of the first sliding tray 11. Similarly, the second individual sensor coil 53 is part of the second sliding tray 21.

[0306] Figure 10 a shows the situation after the first sliding tray 11 has been closed. Figure 9 c is the aerosol generation system. The second chamber 20 is still empty.

[0307] Figure 10 A also indicates an optional layer of shielding material 130, which may be arranged in each tray 11, 21 on the side opposite to the corresponding cavity 10, 20 near the corresponding sensor coil 43, 53.

[0308] Figure 10 Figure a also shows an airflow opening 701 for allowing airflow from the first chamber 10 into the first downstream portion 70, and an airflow opening 721 for allowing airflow from the second chamber 20 into the second downstream portion 72.

[0309] The aerosol generating apparatus is configured such that the insertion direction 132 of each of the first sliding tray 11 and the second sliding tray 21 is inclined relative to the first main boundary surface 40 and the second main boundary surface 50 of the heated substrate 30. Preferably, the insertion direction of each of the first sliding tray 11 and the second sliding tray 21 is inclined relative to the first main boundary surface 40 and the second main boundary surface 50 of the heated substrate 30 at an angle "α" between 1 degree and 10 degrees, more preferably between 2 degrees and 7 degrees, and even more preferably between 2 degrees and 5 degrees.

[0310] like Figure 10 As shown in b, the tilt angle “α” is the angle between the insertion direction 132 and the plane 136 extending parallel to the first main boundary surface 40 and the second main boundary surface 50 of the heated substrate 30.

[0311] As the first sliding tray 11 moves diagonally relative to the planar surface 136 of the heating substrate 30, the force applied to close the tray is converted into a vertical force 134 gradually applied to the corresponding bottom main boundary surface 40 of the heating substrate 30, which is maintained when the tray 11 remains fully closed. During this phase of closing the first sliding tray 11, the bottom surface of the corresponding first aerosol generating article 12 comes into full contact with the first discrete heating portion 42 present at the first main boundary surface 40 of the heating substrate 30. Then, the discrete heating portion 42 is in close proximity to the discrete aerosol forming matrix portion 16 arranged on the other side of the main boundary surface 14 of the first aerosol generating article 12, and heat can be transferred from each discrete aerosol forming matrix portion 16 to the corresponding discrete aerosol forming matrix portion 16 through the main boundary surface 14 of the first aerosol generating article 12. This similarly applies to the diagonal movement of the second sliding tray 21.

[0312] The specific design of trays 11, 21 exhibiting angles (as indicated by angle "α") relative to the plane 136 of the heating substrate 30 advantageously helps ensure that once trays 11, 21 are fully closed and remain closed, they are perfectly shut, with all parts and components in close contact. This allows critical parts to remain in close contact, contributing to optimal heat transfer. As the trays gradually close, the angle of sliding movement of trays 11, 21 relative to the plane 136 of the heating substrate 30 surface generates a vertical force, which reaches its maximum when the trays are fully closed. The trays can then be held closed by a locking mechanism that interacts with the corresponding buttons 94, 96. All parts are then in their correct positions, and the main boundary surfaces of the corresponding aerosol-generating articles 12, 22 are in close contact with the corresponding first discrete heating portion 42 or second discrete heating portion 52, while the sealing elements 116, 126 of the corresponding trays 11, 22 are in full contact with the sealing element 34 of the heating substrate 30. This achieves an airtight closure of cavities 10, 20.

[0313] Once the user presses operation buttons 94 and 96 to open the corresponding trays 11 and 21, the trays open, preferably spring-loaded. The user can load trays 11 and 21 by placing the corresponding aerosol-generating articles 12 and 22 into the corresponding first frame structure 112 or second frame structure 122. Once the aerosol-generating articles 12 and 22 are in trays 11 and 21, the user can manually close the trays 11 and 21, which can then remain closed based on a locking mechanism interlocked with the corresponding buttons 94 and 96 by reconfiguring the interlock between the mechanism and the buttons.

[0314] The first sliding tray 11 includes a first cavity 10 as a protruding portion, which is securely surrounded by a frame structure 112 and a sealing element 116. The second sliding tray 21 includes a second cavity 20 as a protruding portion, which is securely surrounded by a frame structure 122 and a sealing element 126. These sealing elements 116, 126 functionally mate with corresponding sealing elements 34 included in the heating substrate 30. Once the trays 11, 21 are closed, their sealing elements 116, 126 are in direct contact with the sealing elements 34 of the heating substrate 30, and each cavity 10, 20 becomes hermetically closed, and this tight contact is maintained by their matching geometry and the elastic properties of their sealing material, as well as by the vertical force 134 applied at the angle of the insertion direction 132 between these sealing elements and the surfaces of the aerosol-generating articles 12, 22 and the surface of the heating substrate 30 once the tray is closed. All these technical solutions and features operate independently in each tray and cavity to independently open and hermetically close.

[0315] When closed, each tray 11, 21 mates with a heating substrate 30 within the device, the heating substrate comprising a plurality of sensor elements 42, 52 corresponding to each portion of the aerosol-forming matrix present in the first aerosol-generating article 12 and the second aerosol-generating article 22. Each tray 11, 21 includes a matrix of a plurality of flat sensor coils 43, 53 paired with the sensor elements 42, 52 of the heating substrate 30. Therefore, the device control unit can manage the power of each individual flat sensor coil 43, 53, and thus generate heat through the paired sensor elements 42, 52, transferring heat to the corresponding aerosol-forming matrix portion to achieve a temperature profile for aerosolization. Driven by the user's inhalation, the generated aerosol flows toward the air outlet for inhalation by the user.

[0316] Figures 7 to 10 The aerosol generating apparatus is also shown, comprising a generally cuboid shape, including two opposing parallel primary boundary surfaces, the two opposing parallel primary boundary surfaces including a first button 94 and a second button 96, and a first operation display 82 and a second operation display 84; and two opposing parallel secondary boundary surfaces, the two opposing parallel secondary boundary surfaces including a first sliding tray 11 and a second sliding tray 21. The first sliding tray 11 and the second sliding tray 21 are arranged in opposing secondary boundary surfaces of the apparatus such that the first sliding tray 11 and the second sliding tray 21 can be opened and closed in opposing directions along a sliding axis substantially perpendicular to the longitudinal central axis 100. The first sliding tray 11 and the second sliding tray 21 are thus present on opposing lateral sides of the aerosol generating apparatus.
