Description

Technical Field

[0002] This disclosure relates to an aerosol generating apparatus for use with an aerosol generating article, and an aerosol generating system including the aerosol generating apparatus. Background Technology

[0003] Aerosol-generating articles, such as those in which an aerosol-generating matrix containing a tobacco matrix is ​​heated rather than burned, are known in the art. In heated aerosol-generating articles, aerosols are generated by heating the aerosol-generating matrix.

[0004] One type of aerosol generation system is an electrically operated smoking system. Known handheld electrically operated smoking systems typically include an aerosol generation device comprising a rechargeable battery, control electronics, and an electric heater for heating an aerosol-generating article specifically designed for use with the aerosol generation device. In some instances, the aerosol-generating article comprises an aerosol-forming matrix, such as a tobacco stick or tobacco rod, and when the aerosol-generating article is inserted into the aerosol generation device, a heater contained within the aerosol generation device is inserted into or positioned around the aerosol-forming matrix.

[0005] A heating element can be incorporated into an aerosol generating apparatus to generate inhalable vapor. Such an apparatus heats the aerosol generating matrix contained within an aerosol generating article without burning the aerosol generating matrix. In doing so, the aerosol generating matrix can generate an aerosol, which can then be delivered to a user.

[0006] Such aerosol-generating articles can be in the form of conventional cigarettes. In this case, the aerosol-generating matrix can be wrapped in cigarette paper. This method may be suitable when the aerosol-generating matrix comprises strands or strips of material (e.g., strands of cast tobacco or strands of shredded tobacco).

[0007] However, this method may not be effective in preserving other forms of aerosol generating matrix, such as particulate or powdered aerosol generating matrices. Such aerosol generating articles may be susceptible to leakage of the aerosol generating matrix during their storage, handling, and use. Leakage of the aerosol generating matrix can be exacerbated by high ambient temperatures and humidity. Loss of the aerosol generating matrix through leakage can adversely reduce the lifespan of aerosol generating articles that include the aerosol generating matrix. Leakage of the aerosol generating matrix can negatively impact the overall performance of the aerosol generating article. For example, leakage of the aerosol generating matrix can negatively affect the consistency of the inhalable aerosols generated by an aerosol generating system that includes the aerosol generating article.

[0008] To provide an aerosol generating article in which the loss or leakage of the aerosol generating matrix is ​​reduced or prevented even when the aerosol generating article is heated to the temperature required to generate aerosols from the aerosol generating matrix, an aerosol generating article comprising a container may be provided. Such an aerosol generating article may be able to retain different forms of the aerosol generating matrix, such as granular or powdered aerosol generating matrix. Such aerosol generating articles comprising containers can be easily handled and operated by the consumer when used with a suitable aerosol generating apparatus. However, prior art aerosol generating apparatuses may not be suitable for heating aerosol generating articles comprising containers. For example, inserting a heating element into an aerosol generating article comprising a container may adversely cause leakage of the aerosol generating matrix from the container. Additionally, existing heaters configured to externally heat the aerosol generating article may not provide effective heating sufficient to generate a consistent aerosol from an aerosol generating article comprising a container.

[0009] There is a need for an aerosol generating apparatus suitable for use with an aerosol generating article, such as an aerosol generating article including a container.

[0010] There is a need for an aerosol generating apparatus that allows users to insert and remove aerosol-generated articles from the apparatus in a simple and convenient manner. Summary of the Invention

[0011] According to a first aspect of this disclosure, an aerosol generating apparatus is provided for use with an aerosol generating article. The aerosol generating apparatus may include a first portion including a first housing including a recess for receiving an aerosol generating article. The aerosol generating apparatus may include a second portion including a second housing and a heater assembly configured to heat the aerosol generating article when received in the recess. The aerosol generating apparatus may include a connecting mechanism connecting the first housing to the second housing and configured to allow relative movement between the first and second housings between a closed position, in which the recess is closed by the second portion, and in an open position, the recess is opened for insertion of the aerosol generating article.

[0012] Providing a connection mechanism to connect the first housing to the second housing prevents the first housing from being separated from the second housing by the user, as the connection mechanism connects the first housing to the second housing in both the open and closed positions. Conveniently, this prevents either the first or second part of the device from being removed from the device and potentially misplaced by the user.

[0013] Furthermore, the connecting mechanism allows the aerosol generating device to be held with one hand and its relative movement between the open and closed positions to be operated. Advantageously, holding the aerosol generating device with one hand and moving it between the open and closed positions facilitates the insertion of the aerosol-generating article into the recess. For example, a user can hold the aerosol generating device with one hand and operate the relative movement of the first and second housings with the same hand, while simultaneously holding the aerosol-generating article with the other hand and inserting it into the recess.

[0014] While the second part includes the heater assembly, the recess in the first part of the housing for receiving the aerosol-generating article allows the user to insert the aerosol-generating article into the aerosol-generating device without direct interaction between the user and the heater assembly. Advantageously, this allows the heater assembly to be protected from potential damage during loading and unloading of the aerosol-generating article into and from the device.

[0015] The connecting mechanism may include a hinge mechanism, wherein the first housing is connected to the second housing via a hinge. Alternatively or additionally, the connecting mechanism may include a rotating mechanism, wherein the connecting mechanism connects the first housing to the second housing and allows at least one of the first housing and the second housing to rotate relative to the other housing.

[0016] Preferably, the connecting mechanism includes a sliding mechanism that connects the first housing to the second housing and is configured to allow relative movement between a closed position and an open position, wherein in the closed position the recess is closed by a second portion, and in the open position the recess is open for insertion of the aerosol-generating article. The connecting mechanism may consist of a sliding mechanism.

[0017] The sliding mechanism provides a simple and robust connection, facilitating the handling of the aerosol generator with one hand and the operation of relative movement between the open and closed positions. The sliding mechanism is also relatively simple to manufacture, offering a straightforward and robust connection.

[0018] The sliding mechanism can be configured to allow the second housing to translate relative to the first housing between an open position and a closed position. The sliding mechanism can also be configured to allow the first housing to translate relative to the second housing in a single plane. Furthermore, the sliding mechanism can be configured to allow the first housing to translate between a first plane and a second plane.

[0019] The first housing may include at least a first portion of the sliding mechanism. The second housing may include at least a second portion of the sliding mechanism. The first portion of the sliding mechanism may be configured to engage with the second portion of the sliding mechanism. The first portion of the sliding mechanism may include a protrusion, and the second portion of the sliding mechanism may include a recess that engages with the protrusion. Alternatively or additionally, the second portion of the sliding mechanism may include a protrusion, and the first portion of the sliding mechanism may include a recess that engages with the protrusion. For example, the sliding mechanism may include a linear sliding guide or a guide rail. The second portion of the sliding mechanism may include a track, and the first portion of the sliding mechanism may include a guide that engages with the track. Alternatively or additionally, the first portion of the sliding mechanism may include a track, and the second portion of the sliding mechanism may include a guide that engages with the track.

[0020] Optionally, the aerosol generating device may include a locking mechanism that holds the device in a closed position. The locking mechanism can advantageously prevent accidental movement of the first housing relative to the second housing during use.

[0021] The aerosol generating device may include a latching element arranged to hold the device in the open position. Advantageously, the latching element can reduce the risk of the first housing accidentally moving out of the open position.

[0022] In the open position, the heater assembly may not be longitudinally aligned with the recess. In the closed position, the heater assembly may be longitudinally aligned with the recess.

[0023] As used herein with reference to the present invention, the term "longitudinal" refers to the direction corresponding to the main longitudinal axis of the aerosol generating apparatus or a portion thereof, which extends between the upstream and downstream ends of the aerosol generating apparatus or a portion thereof.

[0024] As used herein with reference to the present invention, the terms “upstream” and “downstream” describe the relative position of an element or portion of an element of an aerosol generating apparatus with respect to the direction in which aerosols are transported through the aerosol generating apparatus during use.

[0025] The heater assembly can be positioned opposite the first part in the open position. For example, in the open position, the heater assembly can be shielded by the first part to prevent user contact. In both the open and closed positions, the user may be unable to access the heater assembly. Advantageously, this protects the heater assembly from accidental damage.

[0026] The heater assembly may include a heating element. The heater assembly may include a resistance heating element. During use, current may be supplied to the resistance heating element to generate heat through resistance heating.

[0027] Suitable materials for forming resistance heating elements include, but are not limited to: semiconductors (such as doped ceramics), electrically "conductive" ceramics (such as, for example, molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel, nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys, as well as superalloys based on nickel, iron, cobalt, stainless steel, Timetal®, and iron-manganese-aluminum based alloys.

[0028] The resistance heating element may include one or more stamped portions of a resistive material (such as stainless steel). Alternatively, at least one resistance heating element may include a heating wire or filament, such as a Ni-Cr (nickel-chromium), platinum, tungsten, or alloy wire.

[0029] The resistance heating element may include at least one electrically insulating substrate, wherein the resistance heating element is disposed on the at least one electrically insulating substrate.

[0030] At least one electrically insulating substrate may comprise any suitable material. For example, the electrically insulating substrate may comprise one or more of paper, glass, ceramics, anodized metals, coated metals, and polyimide. Ceramics may comprise mica, alumina (Al2O3), or zirconium oxide (ZrO2). The electrically insulating substrate may have a thermal conductivity of less than or equal to about 40 W / m Kelvin, preferably less than or equal to about 20 W / m Kelvin, and ideally less than or equal to about 2 W / m Kelvin.

[0031] The resistance heating element may include a heating element comprising a rigid electrically insulating substrate having one or more conductive tracks or lines disposed on its surface. In use, an electric current can pass through one or more conductive tracks to heat the resistance heating element and an aerosol-generating matrix received within the recess.

[0032] The heater assembly may include an induction heating element. During use, the induction heating element inductively heats at least one sensor material to heat an aerosol-generating article received within a recess. The at least one sensor material may form part of an aerosol-generating apparatus. The induction heating element may include at least one sensor coil configured to generate an alternating magnetic field. During use, the alternating magnetic field is configured to inductively heat the sensor material.

[0033] The induction heating element can be connected to a power source configured to supply a high-frequency oscillating current to the inductor coil. As used herein, a high-frequency oscillating current means an oscillating current with a frequency between approximately 500 kHz and approximately 30 MHz. The inductor coil can be arranged to generate an alternating magnetic field when receiving the high-frequency oscillating current from the power source. The inductor coil can be arranged to generate an alternating magnetic field within a recess.

[0034] A heater including an induction heating device can be advantageously used in combination with an aerosol-generating article including a sensor element.

[0035] The receptor element may include any suitable receptor element.

[0036] In some embodiments, the heater assembly may include at least one resistance heating element and at least one induction heating element. In some embodiments, the heater assembly may include a combination of resistance heating elements and induction heating elements.

[0037] In the closed position, the heater assembly can at least partially close the recess. Preferably, in the closed position, the recess is closed by the heater assembly.

[0038] The heater assembly may include a heating element and a support element for supporting the heating element.

[0039] Preferably, the support element may comprise a heat-resistant and non-conductive material. The support element may comprise a heat-resistant polymer. For example, the support element may comprise polyetheretherketone (PEEK). The support element may be made of PEEK. The support element may comprise ceramic. For example, the support element may comprise alumina. In another example, the support element may comprise zirconium oxide.

[0040] The heater assembly may include a sealing member to seal the aerosol-generated article within the recess during heating. The heating element may be mounted on the sealing member. A support element may include the sealing member.

[0041] The heating element can be mounted on the surface of the sealing member facing the recess.

[0042] Preferably, the heating element can be elastically mounted on the sealing member, such that the heating element is elastically pushed into the recess.

[0043] Advantageously, providing a heating element that is elastically pushed into the recess can improve the contact between the heating element and the aerosol-generating article during heating, thus improving aerosol generation.

[0044] The sealing member can be configured to deform at least a portion of the aerosol-generating article to seal the aerosol-generating article within the recess.

[0045] The heating element can protrude from the sealing member toward the recess to allow the heating element to directly contact the aerosol-generated article.

[0046] The heating element can be integrated with the sealing component. The heating element can be fixedly attached to the sealing component.

[0047] The sealing member may include a sealing frame having a peripheral structure surrounding the orifice, wherein the sealing frame is configured to seal the periphery of the recess. A heating element may extend across the orifice. The sealing frame may be configured to provide mechanical support to the heating element.

[0048] The support element may also include a retaining member for securing the heater to the sealing member. The retaining member may be movable relative to the sealing member. For example, the retaining member may be movable relative to the sealing frame such that at least a portion of the retaining member can enter an orifice to push the heating element toward the recess. The retaining member may comprise a heat-resistant and non-conductive material. For example, the retaining member may comprise polyetheretherketone (PEEK). The retaining member may be made of PEEK.

[0049] The heater assembly is movable between a sealed position and an unsealed position. In the sealed position, the sealing member seals the recess; in the unsealed position, the sealing member is spaced apart from the recess. Preferably, the heater assembly is in the sealed position when the first housing and the second housing are in the closed position. Preferably, the heater assembly is in the unsealed position when the first housing and the second housing are in the open position.

[0050] The aerosol generating apparatus may include a clamping mechanism configured to allow relative movement between a recess and at least a portion of a heater assembly in response to relative movement between a first housing and a second housing.

[0051] Advantageously, a clamping mechanism configured to allow relative movement between the recess and at least a portion of the heater assembly allows the heater assembly to move toward the recess and thus toward the aerosol-generating article during use. Advantageously, the contact between the heater assembly and the aerosol-generating article can be improved. As a result, more reliable heating of the aerosol-generating article and more consistent aerosol generation can be achieved.

[0052] Advantageously, the provision of the clamping element allows the aerosol-forming article to remain in the same position within the aerosol-generating apparatus each time it is loaded. For example, since the clamping mechanism is actuated in response to the relative movement of the first and second housings, the force applied to the aerosol-generating article by the heater assembly during loading can be consistent each time, as this force is applied by the clamping mechanism, not by user insertion. Therefore, the distance between the heater assembly and the recess can be the same each time after loading the aerosol-generating article. Advantageously, this improves the consistency of heating and aerosol generation.

[0053] The clamping mechanism can be configured to allow relative movement between the recess and the heater assembly. In particular, the heater assembly may include a heating element, and the clamping mechanism can be configured to allow relative movement between the recess and the heating element.

[0054] The connecting mechanism can be configured to allow relative movement between the first housing and the second housing in a first plane. The clamping mechanism can be configured to allow relative movement between the recess and at least a portion of the heater assembly in a second plane. The first plane can be perpendicular to the second plane.

[0055] The connecting mechanism may be a separate component from the clamping mechanism. The clamping mechanism may not contact the first part of the device. Preferably, the clamping mechanism does not contact the first housing. The clamping mechanism may be configured to allow the heater assembly to move toward the recess.

[0056] The clamping mechanism may include a resilient element configured to allow relative movement between the recess and at least a portion of the heater assembly. Preferably, a support element is resiliently mounted on a second housing via the resilient element, such that the heating element is resiliently pushed toward the recess. The resilient element may be attached to the support element. The resilient element may be attached to a fixing member.

[0057] Preferably, the clamping mechanism may include a spring configured to allow at least a portion of the heater assembly to move relative to the recess. Advantageously, the spring provides a simple and robust elastic element.

[0058] The spring or any other type of clamping mechanism may include a conductive material. Advantageously, providing a clamping mechanism that includes a conductive material allows the clamping mechanism to supply power to the heater assembly.

[0059] In the second plane, the distance between at least a portion of the heater assembly and the bottom of the recess can be greater in the open position than in the closed position.

[0060] The aerosol generating apparatus may include a power source for supplying electricity to a heater assembly. The power source may be configured to supply power to the heating element when the aerosol generating apparatus is in use. The power source may be located in a second part of the aerosol generating apparatus.

[0061] The power source can be a DC power source. The power source can be a battery. It can be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery, such as a lithium-cobalt battery, a lithium-iron-phosphate battery, or a lithium polymer battery. The power source can also be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity that allows for storing enough energy for one or more user operations (e.g., one or more aerosol generation experiences).

[0062] The aerosol generating device may also include control circuitry. The control circuitry system can be configured to control the power supply from the power source to the heating components.

[0063] The control circuit system can be connected to a power source. The control circuit system can...

[0064] It is connected to the heating element. The control circuitry system can control the power supply from the power source to the heating element. The control circuitry system can control the temperature of the heating element. The control circuitry system may include a controller. The control circuitry system may include a microcontroller. The microcontroller may be a programmable microcontroller. The controller may be located in the second part of the aerosol generating apparatus.

[0065] The recess may include one or more air inlets and one or more air outlets, as well as an airflow path defined between the one or more air inlets and the one or more air outlets.

[0066] At least one air inlet allows air to enter the recess and approach the aerosol-generated article received within the recess. At least one air inlet may be located at the upstream end of the recess. At least one air outlet allows the aerosol to exit the recess for delivery to the user. At least one air outlet may be located at the downstream end of the recess.

[0067] The shortest line connecting any one of the one or more air inlets to any one of the one or more aerosol outlets is not parallel to either the width or the length of the recess.

[0068] Advantageously, providing the shortest line, which is not parallel to each of the width and length of the recess, connecting any one of the one or more air inlets to any one of the one or more air outlets, can increase the length of the airflow path through the recess. Therefore, the contact between the airflow through the aerosol generating device and the aerosol generating matrix of the aerosol generating article received in the recess can be increased.

[0069] Advantageously, providing the shortest line, not parallel to each of the width and length of the recess, connecting any one of the one or more air inlets to any one of the one or more air outlets, can increase the release of active ingredients (such as nicotine and flavoring, or both) from the aerosol-generating matrix of the aerosol-generating article received within the recess into the aerosol. Advantageously, aerosol generation and delivery can be improved throughout the user experience. In particular, advantageously, aerosol generation and delivery can be improved at the end of the user experience.

[0070] It should be understood that the feature "the shortest line connecting any one of the one or more air inlets to any one of the one or more air outlets is not parallel to either the width or the length of the recess" means that there is no air inlet such that the shortest line connecting any one of the air inlets to any one of the aerosol outlets is parallel to the width of the recess, and there is no air inlet such that the shortest line connecting any one of the air inlets to any one of the aerosol outlets is parallel to the length of the recess. Therefore, this also means that the shortest line connecting any one of the one or more aerosol outlets to any one of the one or more aerosol inlets is not parallel to either the width or the length of the recess. In other words, it is possible that there is no line parallel to the width of the recess that intersects both the inlet and outlet of the recess, and it is possible that there is no line parallel to the length of the recess that intersects both the inlet and outlet of the recess. In other words, there may not be a straight line parallel to the width of the recess connecting the entrance and exit of the recess, and there may not be a straight line parallel to the length of the recess connecting the entrance and exit of the recess.

[0071] The shortest line connecting any one of the one or more air inlets to any one of the one or more air outlets of the recess may not be parallel to the longitudinal axis of one or both of the recess and the aerosol generating device. In other words, the one or more air inlets and one or more air outlets of the recess may be offset relative to the longitudinal axis of one or both of the recess and the aerosol generating device.

[0072] The aerosol generating apparatus may include a sensor for detecting airflow through the apparatus. The sensor may be an airflow sensor. Preferably, the sensor is a pressure sensor for detecting airflow through the apparatus.

[0073] The sensor can be configured to detect suction. The sensor allows for control of the heater assembly's heating based on the detection of airflow through the device. Advantageously, the temperature of the heater assembly can be adjusted based on the sensor's measurements. For example, the sensor can detect when a negative pressure is applied to the device's air outlet, such as during user suction. The magnitude and frequency of user suction can be monitored by a controller, which can control the electrical force supplied to the heater assembly in response to sensor measurements.

[0074] A sealed air passage can be provided between the first and second housings. The sensor can measure pressure through this sealed air passage.

[0075] The second part of the aerosol generating apparatus may include a sensor. Advantageously, providing a second part of the aerosol generating apparatus that includes a sensor allows for the placement of electrical components associated with the sensor within the second part of the aerosol generating apparatus. Advantageously, this can reduce the number of electrical connections required between the first and second parts of the apparatus, or it can eliminate the need for electrical connections between the first and second parts of the apparatus. For example, if the power supply for powering the heater assembly, sensor, and control electronics is also included in the second part, this can allow the apparatus to be configured without electrical connections or interfaces between the first and second parts. Advantageously, this simplifies the connection between the first and second housings, simplifies the construction of the apparatus, and improves the reliability of the electrical system by requiring fewer interfaces. Advantageously, electrical interfaces may not be required in the connection mechanism.

[0076] The connection mechanism may include a sensor.

[0077] Alternatively, the first part of the aerosol generating device may include a sensor.

[0078] Providing a sensor within the first section allows the sensor to also function as a contact sensor, configured to detect the electrical connection between the first and second sections. Advantageously, the sensor acting as a contact sensor may be able to detect whether the aerosol generating device is in the off position.

[0079] Advantageously, the first portion of the aerosol generating device, including the sensor and the recess, improves the seal at the location of the sensor in the first portion (where measurements are taken by the sensor). Advantageously, this improves the accuracy of the measurements taken by the sensor.

[0080] In addition to one or more air inlets in the recess, the aerosol generating apparatus may also include a device air inlet for allowing air to enter the aerosol generating apparatus. The device air inlet of the aerosol generating apparatus may be in fluid communication with the air inlet in the recess. The device air inlet may be located on a first device housing portion or a second device housing portion.

[0081] In addition to one or more air outlets in the recess, the aerosol generating device may also include a device air outlet for allowing aerosols to exit the aerosol generating device. The aerosol generating device may include a mouthpiece located at a downstream end of the aerosol generating device. The mouthpiece may be configured as part of the first housing. The mouthpiece may be integral with the first housing. The mouthpiece may be removably attached to the first housing. Advantageously, providing a removable mouthpiece allows the mouthpiece to be removed for cleaning, or the mouthpiece to be replaced without replacing the entire device.

[0082] The device air outlet can be located in the mouthpiece. This device air outlet can be in fluid communication with the air outlet in the recess. A closed air passage can extend between the recessed air outlet and the device air outlet. The closed airflow passage can be configured to allow fluid communication between the recessed air outlet and the device air outlet.

[0083] The sensor can be configured to measure pressure changes between the air inlet of the device and one or more air inlets in the recess.

[0084] Advantageously, configuring a pressure sensor to measure pressure changes between the device's air inlet and one or more air inlets in the recess can reduce the risk of condensation along the airflow path measured by the pressure sensor. Advantageously, configuring a pressure sensor to measure pressure changes between the device's air inlet and one or more air inlets in the recess can reduce the complexity of the pressure sensor arrangement.

[0085] The pressure sensor can be configured to measure the pressure change between the air inlet of the device and one or more air outlets in the recess.

[0086] Advantageously, configuring a pressure sensor to measure the pressure change between the air inlet of the device and one or more air outlets of the recess can improve the reliability of the measurements performed by the pressure sensor.

[0087] The recess may have a length of at least 10 mm. For example, the recess may have a length of at least 12 mm, at least 14 mm, at least 16 mm, or at least 18 mm.

[0088] The recess may have a length not exceeding 30 mm. For example, the recess may have a length not exceeding 28 mm, 25 mm, 20 mm, or 18 mm.

[0089] The recess may have a length between about 10 mm and about 30 mm, between about 12 mm and about 28 mm, between about 14 mm and about 25 mm, or between about 20 mm and about 16 mm.

[0090] The recess may have a length of approximately 14 mm. The recess may have a length of approximately 16 mm. The recess may have a length of approximately 18 mm.

[0091] The recess may include a bottom wall and at least one side wall. For example, the recess may include a side wall extending around the circumference of the recess. The recess may include four side walls. One or more air outlets of the recess may be provided in at least one side wall of the recess.

[0092] According to another aspect of the present invention, an aerosol generation system is provided. The aerosol generation system may include an aerosol generation apparatus and an aerosol generation article.

[0093] The aerosol-generating article can be any aerosol-generating article. The aerosol-generating article may include a container comprising a first wall and a second wall. The first and second walls may together define a matrix compartment. The aerosol-generating matrix may be disposed within the matrix compartment.

[0094] The first wall may be made of a different material than the second wall. The first wall may be a flexible cellulose-based material. The second wall may have higher stiffness than the first wall. Alternatively, the first wall may have higher stiffness than the second wall.

[0095] At least a portion of the first wall may be porous. As used herein with reference to the present invention, the term "cellulose-based material" refers to a material made of cellulose or a derivative of cellulose.

[0096] The first wall can include any cellulosic material. The first wall can also include nonwoven materials.

[0097] The second wall of the aerosol-generated article can come into contact with the heater assembly.

[0098] As used herein with reference to this invention, the term "nonwoven" refers to a manufactured sheet, web, or wadding of oriented or randomly oriented fibers bonded together by friction, and / or cohesion and / or adhesion, excluding products formed by weaving, braiding, tufting, stitching with incorporated yarns or filaments, or by wet felting (whether or not additionally needle-punched). The fibers may be of natural or synthetic origin.

[0099] The first wall may include molded paper material.

[0100] The second wall may be non-porous. The second wall may comprise a substantially planar material. The second wall may comprise a paper material.

[0101] The aerosol-generating matrix may contain at least one alkaloid.

[0102] As used herein with reference to this invention, the term "alkaloid compound" is used to describe any of a class of naturally occurring organic compounds containing one or more basic nitrogen atoms. Typically, alkaloids contain at least one nitrogen atom in an amine-type structure. This or other nitrogen atom in the alkaloid compound molecule can function as a base in acid-base reactions. In most alkaloid compounds, one or more of the nitrogen atoms are part of a cyclic system, such as a heterocycle. In nature, alkaloid compounds are primarily found in plants, and are particularly common in certain flowering plant families. However, some alkaloid compounds are found in animal species and fungi. In the context of this invention, the term "alkaloid compound" is used to describe alkaloid compounds of natural origin and synthetically manufactured alkaloid compounds. Suitable alkaloid compounds for use in aerosol generating elements according to the invention include, but are not limited to, nicotine and neonicotinoids.

[0170] Figure 1A A cross-sectional view of an aerosol generating apparatus 100 according to a first embodiment of the present disclosure is shown in the open position. The aerosol generating apparatus 100 is intended to work with an aerosol generating article (…). Figure 1A (Not shown in the image) Used together. The device 100 includes a first portion 101 and a second portion 102. The first portion 101 includes a first housing 103, and the second portion 102 includes a second housing 104.

In the closed position, the recess 110 is closed by the second portion 102 of the aerosol-generating device 100. In the open position, the recess 110 is open for insertion of the aerosol-generated article.

[0171] The connecting mechanism 112 is a sliding mechanism 114 that connects the first housing 103 to the second housing 104, and is configured to allow the first housing 103 and the second housing 104 to be in a closed position. Figure 1C ) and opening position ( Figure 1A , 1B The sliding mechanism 114 is configured to allow the first housing 103 to translate relative to the second housing 104 between an open position and a closed position.

[0172] The second part 102 includes a heater assembly 106 configured to heat the aerosol-generating article when it is received in the recess 110.

[0173] Device 100 includes device air inlet ( Figure 1A (not shown in the image), and the recess 110 includes one or more air inlets and one or more air outlets (not shown in the image), Figure 1A (Not shown). The airflow path is defined between one or more air inlets and one or more air outlets. The device air inlets are in fluid communication with one or more air inlets. The device 100 also includes a device air outlet (not shown) in fluid communication with one or more air outlets of the recess.

[0174] The mouthpiece 105 is located at the downstream end of the aerosol generating device 100, and the mouthpiece 105 includes the device air outlet. Figure 1A , 1B The mouthpiece 105 shown in 1C is integral with the first housing 103. However, it should be understood that, alternatively, the mouthpiece 105 may be removably attached to the first portion 101.

[0175] The second part 102 includes a power supply 108 and a controller 109 electrically connected to the heater assembly 106. The power supply 108 is configured to supply power to the heater assembly 106, while the controller 109 is configured to control the power supply.

[0176] The second part 102 includes a pressure sensor 107 for detecting the airflow through the aerosol generating device 100. However, it should be understood that the pressure sensor may alternatively be located in the first part 101. A power supply 108 and a controller 109 are also electrically connected to the sensor 107.

[0177] Figure 1B A cross-sectional view of an aerosol generating apparatus 100 according to a first embodiment of the present disclosure is shown in the open position, wherein an example of an aerosol generating article 70 has been received in a recess 110. Figure 1C A cross-sectional view of an aerosol generating apparatus 100 according to a first embodiment of the present disclosure is shown in the closed position, the aerosol generating apparatus having received an aerosol generating article 70 within a recess 110. The aerosol generating apparatus and the aerosol generating article received in the recess may be collectively referred to as an aerosol generating system.

[0178] In the closed position, heater assembly 106 is opposite to recess 110 and closes the recess. Heater assembly 106 is located near or in contact with aerosol generating article 70.

[0179] exist Figure 1C In the closed position shown, the aerosol generating apparatus 100 is configured to heat the aerosol to generate article 70.

[0180] Before use and between uses of the aerosol generating device 100, the user can keep the device in the closed position. To use the device, the user moves the first housing 103 and the second housing 104 from the closed position to... Figure 1A The diagram shows the open position. In the closed position, the recess 110 is closed by the second portion 102. In the open position, the recess is open for insertion of the aerosol generating article. The user can then insert the aerosol generating article 70 into the recess 110 (see [reference]). Figure 1B The user then moves the first housing 103 and the second housing 104 from the open position. Figure 1C The closed position is shown, in which the recess 110 is closed by the second portion 102. The aerosol generating device is then ready for use.

[0181] In use, the controller 109 supplies power from the power source 108 to the heating element of the heater assembly 106, causing current to flow through the heating element and raising its temperature. Heat is transferred to the aerosol forming article 70, causing the aerosol forming matrix of the aerosol forming article 70 to heat up, and volatile compounds to evaporate from the aerosol forming matrix.

[0182] In use Figure 1C During the process of using the apparatus and article shown, a user inhales through mouthpiece 105. During each user inhale, inhalation through mouthpiece 105 of the aerosol generating apparatus 100 causes air to be drawn through the apparatus toward the user's mouth. During inhalation, air is drawn from outside the aerosol generating apparatus through the apparatus air inlet, through the recessed air inlet, and into the recess 110. In the recess 110, the air comes into contact with the aerosol forming matrix of the aerosol generating article 70. The air passes through the aerosol generating article 70 to the recessed air outlet. As the air passes through the aerosol forming matrix, volatile compounds generated by heating the aerosol forming matrix are entrained in the air. As the air continues to flow through the apparatus from the recessed air outlet to the apparatus air outlet, the volatile compounds cool to form an aerosol, which is then inhaled by the user of the apparatus.

[0183] Figure 2 It shows the closed position. Figure 1A-1C A cross-sectional view of a portion of an aerosol generating device. (See diagram below.) Figure 2 As shown, when the device is in the closed position, the heater assembly 106 closes the recess. The heater assembly 106 includes a heating element 120 and a support element 122 configured to provide mechanical support to the heating element. Figure 2In the example shown, the support element 122 includes a sealing member 124 configured to deform at least a portion of the aerosol-generating article within the recess 110 to seal the aerosol-generating article within the recess 110 during heating. The support element 122 also includes a fixing member 126 for securing the heating element 120 to the sealing member 124.

[0184] The heating element 120 is mounted on the sealing member 124 facing the recess 110, such that during heating, the surface of the heating element 120 will face or contact the aerosol-generated article. Figure 2 In the example shown, the heating element 120 is fixedly attached to the sealing member 124. However, it should be understood that in other examples, the heating element 120 may be integral with the sealing member 124. The heating element 120 protrudes from the sealing member 124 toward the recess 110 to allow the heating element 120 to directly contact the aerosol-generated article when the article is received in the recess 110.

[0185] The sealing component 124 is made of polyetheretherketone (PEEK).

[0186] The recess 110 includes a recess air inlet 111 and a recess air outlet, wherein an airflow path is defined therebetween, such that in use, the airflow travels directly through the aerosol-generated article received within the recess 110.

[0187] Figure 3 A perspective view of a recess 210 in an aerosol generating apparatus according to a second embodiment of the present disclosure is shown. The aerosol generating apparatus includes the features described above. Figure 1A-2 All features of the aerosol generating device 100 described herein are explained unless otherwise stated below. The recess 210 includes an air inlet 211 and an air outlet 212. The width 221, length 222, and depth 223 of the recess 210 are shown.

[0188] The shortest line 224 connecting the air inlet 211 and the air outlet 212 is not parallel to the width 221 of the recess 210. The shortest line 224 connecting the air inlet 211 and the aerosol outlet 212 is not parallel to the length 222 of the recess 210.

[0189] Air inlet 211 is at a first depth, and aerosol outlet 212 is at a second depth. The first depth and the second depth are different.

[0190] The recess 210 includes a bottom wall 205 and side walls. The side walls include an upstream side wall 206 and a downstream side wall 207.

[0191] An air inlet 211 is located in the upstream sidewall 206. An air outlet 212 is located in the downstream sidewall 207.

[0192] The distance between air outlet 212 and bottom wall 205 is less than the distance between air inlet 211 and bottom wall 205. In an alternative embodiment, the distance between air outlet and bottom wall may be the same as or greater than the distance between air inlet and bottom wall.

[0193] Figure 4 A perspective view of a heating element 220, a heating element 220 mounted on a sealing member 224, and a heater assembly 206 for an aerosol generating apparatus according to a third embodiment of the present disclosure is shown. The heater assembly 206 includes the heating element 220, the sealing member 224, and the fixing member 226. The heater assembly 206 is an alternative example of a heater assembly suitable for the aerosol generating apparatus of the present disclosure. The aerosol generating apparatus according to the third embodiment of the present disclosure includes all the features described above with respect to aerosol generating apparatus 100, unless otherwise stated below with respect to heater assembly 206.

[0194] Heating element 220 is a resistance heating element; however, it should be understood that, alternatively or additionally, the heater assembly may include an induction heating element.

[0195] The sealing member 224 includes a sealing frame 225 configured to seal the periphery of the recess. The sealing frame 225 has a peripheral structure surrounding the orifice 227. Figure 4 As shown, heating element 220 extends across orifice 227. Sealing frame 225 is configured to provide mechanical support to heating element 220.

[0196] The heater assembly 206 also includes a retaining member 226 made of PEEK. The retaining member 226 is mounted to the sealing member 224.

[0197] The heater assembly 206 is positioned in the second part of the aerosol generating device such that the spring 228 is configured to elastically push the heater assembly 206 toward the recess.

[0198] Figure 5A and 5B A schematic cross-sectional view of a portion of an aerosol generating apparatus 300 according to a fourth embodiment of the present disclosure is shown. Figure 5A and Figure 5B The aerosol generating device 300 is substantially the same as the aerosol generating device 100 and operates in substantially the same manner, unless otherwise stated below.

[0199] exist Figure 5A and Figure 5BIn the illustrated device, the heater assembly 306 is resiliently mounted to an internal portion of the second housing 304 via a clamping mechanism 330 comprising two leaf springs 335. The device may alternatively include one, three, or four leaf springs. The leaf springs 335 are configured to allow the heater assembly to respond to the second housing portion 304 relative to the first housing 303 from... Figure 5A The opening position shown is moved to Figure 5B The closed position shown in the figure Figure 5A The unclamped position shown is the same as Figure 5B The device moves between the clamping positions shown. In the open position, the heater assembly 306 closes the recess 310, allowing the aerosol-generating article received in the recess 310 to be heated by the heating element 320 of the heater assembly 306 during use. In the clamping position, the leaf spring 335 elastically deforms to apply a force toward the bottom of the recess 310 towards the heater assembly 306. Therefore, the heater assembly applies a force to the aerosol-generating article received in the device.

[0200] The heating element 320 is elastically mounted to the support element 322 via an elastic member 340. In this example, the elastic member 340 comprises two leaf springs. However, it should be understood that the aerosol generating device 300 can be implemented with a heating element 320 fixedly mounted to the support element 322 without the elastic member in between.

[0201] The aerosol generating apparatus also includes a stop 350 positioned in a first part of the apparatus to limit relative movement between the heater assembly 306 and the recess 310. When the apparatus moves from the open position to the closed position, upon reaching the closed position, the heater assembly 306, particularly the support element 322, abuts the stop 350, thus maintaining the longitudinal position of the heater assembly 306 relative to the recess 310.

[0202] Advantageously, the leaf spring 335 can be made of a conductive material to supply electricity from the power source of the aerosol generating device to the heater assembly 306 to heat the heating element 320.

An aerosol forming matrix 714 is disposed within the matrix compartment.

[0204] exist Figure 6In the example shown, the first wall 711 is formed of a nonwoven cotton material. The first wall 711 contains between 85% and 90% by weight of cellulose, between 7% and 16% by weight of hemicellulose, and between 1% and 3% by weight of lignin. The first wall 711 is porous.

[0205] The second wall 712 comprises paper. The second wall 712 has a basis weight of approximately 35 gsm. The second wall is non-porous.

[0206] The second wall 712 is basically planar. The second wall 712 has higher stiffness than the first wall 711. In this way, the first wall 711 can be substantially formed into a bag shape closed by the second wall 712.

[0207] An aerosol forming matrix 714 is disposed in a matrix compartment 713. The aerosol forming matrix 714 comprises homogenized tobacco material particles and an aerosol forming agent. The aerosol forming agent includes glycerol. The matrix compartment 713 contains approximately 150 mg of the aerosol forming matrix 714.

[0208] When using an aerosol generating apparatus according to any embodiment of this disclosure, with the aerosol generating apparatus in the open position, an aerosol generating article 700 is inserted into the recess. The first wall 711 of the article contacts the recess. Then, a second portion of the apparatus moves relative to the first portion to a closed position. In the closed position, the heater assembly of the aerosol generating apparatus contacts the second wall 712 of the aerosol generating article, such that the heater assembly can heat the aerosol forming matrix 714 of the aerosol generating article.
