Description

[0001] This invention relates to an aerosol generating device, particularly a handheld device, configured to generate an aerosol to be inhaled by a consumer by heating an aerosol generating matrix sheet. The invention also relates to an aerosol generating system comprising an aerosol generating device and an aerosol generating matrix sheet. Furthermore, the invention relates to an aerosol generating article for use with the aerosol generating device.

[0002] Aerosol generating devices in which the aerosol generating matrix is ​​heated rather than burned are known in the art. Typically, in such devices, aerosols are generated by transferring heat from a heat source to an aerosol generating matrix, which may be located near or in contact with the heat source. Alternatively, aerosols may be generated by vibration or other means. Aerosol generating devices are known to be powered by an energy source such as a rechargeable battery.

[0003] The present invention aims to provide an improved aerosol generating apparatus. The present invention also aims to provide an improved aerosol generating article for use in the aerosol generating apparatus.

[0004] According to a first aspect of the present invention, an aerosol generating apparatus is provided, comprising: at least one aerosolizing element configured to generate an aerosol from an aerosol generating matrix sheet; a clamp configured to clamp and release the aerosol generating matrix sheet; and a conveying unit configured to move the aerosol generating matrix sheet relative to the at least one aerosolizing element and through the clamp. The clamp has: a closing configuration in which movement of the aerosol generating matrix sheet through the clamp is restricted; and an opening configuration in which the conveying unit can move the aerosol generating matrix sheet through the clamp.

[0005] By restricting the movement of the aerosol-generating matrix sheet through the clamp, the aerosol-generating matrix sheet can be kept stationary during aerosol generation. Undesirable or unintentional displacement of the aerosol-generating matrix sheet can be advantageously prevented in a closed configuration. The aerosol-generating matrix sheet can be held relative to at least one aerosolizing element. In particular, at least one aerosolizing element remains stationary relative to the aerosol-generating matrix sheet during the consumer's aspiration, especially during a single inhalation. This allows a portion of the matrix to pass more thoroughly through the aerosolizing element, thereby aerosolizing a large portion of the aerosolizable contents of the matrix during aspiration.

[0006] A closed structure can form a heating structure for heating the aerosol generation matrix sheet. By restricting the movement of the aerosol generation matrix sheet, a defined portion of the aerosol generation matrix sheet can be thoroughly heated. This is true even when the aerosol generation apparatus is subjected to acceleration and external forces caused by the consumer operating the aerosol generation apparatus. Repeated heating of the same portion of the aerosol generation matrix sheet can be prevented by moving the aerosol generation matrix sheet by at least one length of aerosolizing element via a clamp.

[0007] The fixture may include at least two clamping elements, wherein at least one of the clamping elements is configured to move relative to the other clamping element. The at least two clamping elements may restrict the movement of the aerosol-generating matrix sheet through the fixture.

[0008] The transfer unit can be configured to move the aerosol-generating matrix sheet between at least two clamping elements.

[0009] One or both of the at least two clamping elements may be arranged within the housing of the aerosol generating apparatus and movable relative to the housing. In the open configuration, the at least two clamping elements may be arranged to be sufficiently separated from each other by a clamping distance to allow movement of the aerosol generating matrix sheet without contact with at least one of the clamping elements. The clamping distance is the distance between the at least two clamping elements in the open configuration of the clamp. The clamping distance is at least 0.1 mm, particularly at least 0.2 mm, and more particularly at least 1 mm or at least 2 mm. The clamping distance may be less than 20 mm. The clamping distance may be less than 10 mm. The clamping distance may be less than 5 mm, particularly less than 3 mm, and more particularly less than 2 mm. This reduces the risk of tearing the aerosol generating matrix sheet when moving it through the clamp. The clamping distance may be between 6 mm and 10 mm. This improves the compactness of the aerosol generating apparatus.

[0010] In the closed configuration of the clamp, an aerosolization chamber can be formed between at least two clamping elements. The aerosolization chamber can provide a primary encapsulation volume in which aerosols can be generated from an aerosol generation matrix sheet. The aerosol generation device can include at least one air inlet and at least one air outlet. The aerosolization chamber can include at least one air inlet and at least one air outlet. At least one air inlet of the aerosolization chamber can be in fluid communication with at least one air inlet of the aerosol generation device. At least one air outlet of the aerosolization chamber can be in fluid communication with at least one air outlet of the aerosol generation device. At least one air inlet of the aerosolization chamber, and correspondingly at least one air outlet, can be formed by a passage connecting the interior of the aerosolization chamber to the exterior of the aerosolization chamber. Aerosols can be generated within the interior of the aerosolization chamber. The passage can be formed by a through-hole provided in at least one of the at least two clamping elements. Alternatively, the passage can be formed by a recess provided in at least one of the at least two clamping elements. The passage can only be formed when the clamp is in the closed configuration.

[0011] In a closed configuration, the clamps may allow airflow only through at least one air inlet of the aerosolization chamber. In a closed configuration, the clamps may allow aerosol flow only through at least one air outlet of the aerosolization chamber. By restricting fluid exchange, particularly heat exchange, the aerosolization chamber allows for reduced heat loss in the closed configuration. The closed configuration of the clamps can maintain the aerosol-generated sheet matrix within the aerosolization chamber. This allows for consistent and stable aerosolization in the closed configuration. The aerosolization chamber formed between at least two clamping elements can be the only aerosolization chamber in the aerosol generation apparatus. The aerosol generation apparatus can be configured such that the aerosolization of the aerosol-generated sheet matrix occurs only within the aerosolization chamber. The aerosol generation apparatus can be configured such that the aerosol generated in the aerosolization chamber can exit the aerosolization chamber only through at least one air outlet. This allows for prevention of aerosol flow to other areas of the aerosol generation apparatus.

[0012] The discrete portions of the aerosol-generating matrix sheet arranged within the aerosolization chamber can correspond to the amount of matrix required for a single inhalation. This prevents the heating of more aerosol-generating matrix than is needed for a single inhalation.

[0013] In the closed configuration of the clamp, at least two clamping elements can be configured to bring at least one aerosolization element into surface contact with the aerosol-generating matrix sheet. Surface contact between at least one aerosolization element and the aerosol-generating matrix sheet can allow for improved aerosolization of the aerosol-generating matrix sheet. When the at least one aerosolization element is a heater element, direct physical surface contact can improve heat exchange between the aerosol-generating matrix sheet and the heater element. The at least two clamping elements can be identical in shape and size. This simplifies the manufacture of the device. Alternatively, the at least two clamping elements can have different shapes or sizes, or both. This can improve clamping or aerosolization (especially heating), or both.

[0014] At least one aerosolization element can be mounted to the fixture. The fixture with the aerosolization element allows for simultaneous aerosolization and clamping of the aerosol-generating matrix sheet. The clamped portion of the aerosol-generating matrix sheet can be thoroughly aerosolized. This allows for uniform aerosolization of the clamped aerosol-generating matrix sheet using at least one aerosolization element. In particular, it reduces or avoids underheating of areas of the aerosol-generating matrix sheet. At least one aerosolization element can be configured to aerosolize only the clamped portion of the aerosol-generating matrix sheet. When the transfer unit is configured to move the aerosol-generating matrix sheet through the fixture in an open configuration, different portions of the aerosol-generating matrix sheet can be clamped and aerosolized between consecutive suction cycles. This prevents some areas of the aerosol-generating matrix sheet from being aerosolized twice. In particular, this allows for the avoidance of potential overheating of some areas of the aerosol-generating matrix sheet. Each of the at least two clamping elements may be provided with at least one corresponding aerosolization element. The aerosolization element may be disposed on each clamping element such that both opposite sides of the aerosol-generating matrix sheet can be aerosolized, particularly simultaneously aerosolized. At least one aerosolization element may include at least one of the following: an electric heater, a dielectric heater, a resistance heater, an induction heater, a sensor, a microwave heater, and an ultrasonic transducer. The ultrasonic transducer may be electrically connected to an ultrasonic generator.

[0015] The fixture may be provided with two or more aerosolization elements. Redundancy of aerosolization elements can help manage potential failures of one aerosolization element. The fixture may include a first clamping element and a second clamping element. The first clamping element may include a first aerosolization element, and the second clamping element may include a second aerosolization element. The first aerosolization element may be an aerosolization element of a different type than the second aerosolization element. Alternatively, the first and second aerosolization elements may be of the same type. In particular, the first and second aerosolization elements may be heating elements, respectively. The first and second aerosolization elements may be configured to heat the aerosol-generating matrix sheet at different temperatures or for different durations, or at different temperatures and for different durations. The first aerosolization element may be configured to heat one side of the aerosol-generating matrix sheet at a higher temperature than the opposite side of the aerosol-generating matrix sheet to which the second aerosolization element is configured to heat. The first aerosolization element may be configured to heat one side of the aerosol-generating matrix sheet for a longer period of time than the second aerosolization element is configured to heat the opposite side of the aerosol-generating matrix sheet. Alternatively, the first and second aerosolization elements may be configured to operate at the same heating temperature or for the same period of time, or at the same heating temperature and for the same period of time. The heating temperature or heating duration, or both, of each aerosolization element may be defined according to the chemical properties of the aerosol-generating matrix sheet. The aerosol-generating matrix sheet may include two opposite sides with different chemical properties. The aerosol-generating matrix sheet may have a side coated with an additive and an opposite side without an additive.

[0016] At least one of the clamping elements may have a cavity. In a closed configuration, the cavity can provide a volume within the fixture in which aerosol can flow. The cavity can be formed by removing a portion of material from the clamping element, particularly from its thickness. Alternatively, the cavity can be formed simultaneously with the clamping element by a molding process. At least one aerosolizing element can be arranged in a manner that, in the closed configuration of the fixture, a first side of the aerosolizing element can be configured to contact the aerosol-generating matrix sheet, and a second side of the aerosolizing element opposite to the first side can be configured to face the cavity.

[0017] At least 20%, particularly at least 50%, of the periphery of at least one of the clamping elements surrounding the cavity may be adapted to contact the aerosol-generating matrix sheet in the closed configuration.

[0018] At least one of the clamping elements surrounding the cavity may have a friction-increasing device, particularly a rougher surface, or silicone rubber, at least partially provided around its periphery. At least one of the clamping elements surrounding the cavity may also have a sealing element at least partially provided around its periphery. The sealing element may be made of silicone rubber. The friction-increasing device and the sealing element may be the same element, particularly an element made of silicone rubber.

[0019] The clamp may have at least two clamping elements, and the corresponding periphery of each clamping element may be configured to form a form-fitting connection with each other in a closed configuration. Specifically, the periphery of the first clamping element may be at least partially provided with a recess or groove, and the periphery of the second clamping element may be at least partially provided with a tongue, such that in the closed configuration of the clamp, the tongue can at least partially engage in the recess of the groove. This allows for improved mechanical stability of the clamp in a closed configuration.

[0020] The aerosol generating device may include a housing having a mouthpiece for inhalation by a consumer, and only one of at least two clamping elements may be fixedly mounted to the housing of the aerosol generating device. One of the at least two clamping elements may remain stationary relative to the housing of the aerosol generating device. The clamp may be disposed inside or within the housing of the aerosol generating device. The clamp may be formed differently from the housing of the aerosol generating device.

[0021] The housing of the aerosol generation apparatus may include a storage compartment for storing aerosol generation matrix sheets, particularly for storing a portion of the aerosol generation matrix sheets upstream of the aerosolization element relative to the conveying direction of the aerosol generation matrix. The storage compartment may be configured as a tube for storing the aerosol generation matrix sheets. The housing of the aerosol generation apparatus may also include a waste compartment for storing the aerosol generation matrix sheets, particularly for storing a portion of the aerosol generation matrix sheets downstream of the aerosolization element.

[0022] The aerosol generating device may include a housing with a mouthpiece for a consumer to inhale, and each of at least two clamping elements may be movably mounted to the housing of the aerosol generating device. Advantageously, this allows for a more uniform clamping force. The at least two clamping elements may be mechanically coupled to each other by means of an elastic element. The elastic element may be a compression spring or a torsion spring. At least one of the clamping elements may be mechanically coupled to an actuator. Movement of the actuator may be transmitted to one of the clamping elements, which is configured to transmit movement to the other clamping elements by means of the elastic element. The elastic element allows actuation of at least two clamping elements by means of a shared actuator.

[0023] The conveying unit may include a first moving mechanism and a second moving mechanism, and a fixture may be arranged between the first and second moving mechanisms. The fixture, the first moving mechanism, and the second moving mechanism may each be actuated by a common motor. Alternatively, the fixture, the first moving mechanism, and the second moving mechanism may be actuated by a single motor. The first moving mechanism may be arranged upstream of the aerosol-generating element relative to the conveying direction of the aerosol-generating matrix. The second moving mechanism may be arranged downstream of the aerosol-generating element relative to the conveying direction of the aerosol-generating matrix. The first moving mechanism may include rollers, particularly a first pair of rollers. The second moving mechanism may include rollers, particularly a second pair of rollers. Each roller may have a corresponding outer diameter between 3 mm and 15 mm, particularly between 4 mm and 10 mm, and more particularly between 4.5 mm and 5 mm. The first pair of rollers and the second pair of rollers may each be actuated by a motor, particularly by a common motor.

[0024] The aerosol generating apparatus may include an eccentric bearing arranged to move at least one of at least two clamping elements. The eccentric bearing may be driven by a motor, particularly a shared motor, or especially a single motor of the aerosol generating apparatus. The eccentric bearing may be configured to convert the rotational motion of the motor into linear motion of at least one of the at least two clamping elements. This linear motion allows the clamp to move between an open and closed configuration. The eccentric bearing may be supported by a rotatable shaft. The rotatable shaft may be coupled to a drive wheel. The drive wheel may be driven by a motor, particularly a shared motor. The eccentric bearing may be configured to move at least one of the clamping elements against the resistance of at least one elastic element. At least one elastic element may connect at least one clamping element to an element stationary relative to at least one clamping element. In particular, at least one elastic element may connect at least one clamping element to the housing of the aerosol generating apparatus. At least one elastic element may include a spring, particularly a compression spring, extension spring, and torsion spring. The spring may be a helical spring, a disc spring, or a leaf spring.

[0025] The direction in which the aerosol-generating matrix sheet is conveyed by means of a conveying unit can be tilted, in particular substantially perpendicular, relative to the direction of movement of at least two clamping elements between the closed and open configurations.

[0026] The aerosol generation apparatus may include a track configured to support an aerosol generation matrix sheet. A conveying unit may be configured to allow the aerosol generation matrix sheet to slide at least partially on the track. The track may include several track segments. A first track segment may be positioned upstream of a first moving mechanism relative to the conveying direction of the aerosol generation matrix sheet. An area defined between the rollers of the first moving mechanism may be free of track. Therefore, the aerosol generation matrix sheet can be conveyed through the rollers of the first moving mechanism. A second track segment may be positioned between the first moving mechanism and a clamp. An area defined between the clamping elements of the clamp may be free of track. This allows the aerosol generation matrix sheet to be clamped between two clamping elements. A third track segment may be positioned between the clamp and a second moving mechanism. An area defined between the rollers of the second moving mechanism may be free of track. This allows the aerosol generation matrix sheet to be conveyed through the rollers of the second moving mechanism. A fourth track segment may be positioned downstream of the second moving mechanism relative to the conveying direction of the aerosol generation matrix sheet. At least one track segment may be covered by a low-friction layer, particularly polytetrafluoroethylene (PTFE).

[0027] The actuation of the clamp, the first moving mechanism, and the second moving mechanism can be mechanically decoupled from each other. A common motor can be configured to actuate the clamp, the first moving mechanism, and the second moving mechanism. The aerosol generating device can be equipped with a single motor. The actuation of the clamp, the first moving mechanism, and the second moving mechanism can be mechanically decoupled from each other by means of freewheel bearings. A first freewheel bearing can be arranged between the motor and the eccentric bearing. The first freewheel bearing allows the motion transmission between the rotatable shaft of the motor and the eccentric bearing to be limited to only one rotational direction. A second freewheel bearing can be arranged between the motor and the first moving mechanism. A third freewheel bearing can be arranged between the motor and the second moving mechanism.

[0028] The aerosol generating device may include a synchronization system comprising a gear mechanism powered by a single motor, wherein a freewheel bearing is used to decouple the movement of the clamping element from the moving mechanism.

[0029] The controller can be configured to activate the delivery unit between consecutive consumer inhalations. The delivery unit can be activated by the controller in response to consumer actions, particularly related individual suctions.

[0030] The controller can be a system with several individual control units. The control units can be connected to transmit data to each other.

[0031] A controller may be configured to activate at least one aerosolization element in response to a consumer's inhalation to aerosolize the aerosol-generating matrix sheet. The controller may be electrically connected to a sensor configured to detect consumer inhalation. The aerosol-generating device may include a sensor for detecting consumer inhalation. The sensor may be positioned upstream of the air inlet of the aerosolization chamber. The sensor may be a flow sensor or a pressure sensor. The flow sensor may be configured to detect changes in airflow occurring when a consumer inhales onto the aerosol-generating device. The pressure sensor may be configured to detect changes in pressure occurring when a consumer inhales onto the aerosol-generating device. The pressure sensor may include a pressure gauge in fluid communication with the air inlet of the aerosol-generating device. Alternatively or in combination, the pressure gauge may be in fluid communication with the air outlet of the aerosol-generating device. The aerosol-generating device may include a capacitive sensor configured to detect when a consumer contacts the aerosol-generating device with their lips to inhale onto the aerosol-generating device. For example, the aerosol-generating device may include a capacitive sensor positioned near a mouthpiece of the aerosol-generating system. The controller may be electrically connected to the capacitive sensor. Alternatively or in combination, the controller may be operatively coupled to an actuation mechanism that can be activated by a consumer to instruct the consumer to inhale. For example, the actuation mechanism may include a switch that can be pressed by a consumer to instruct the consumer to inhale.

[0032] The controller may include a microprocessor or be electrically connected to a microprocessor. The microprocessor may be a programmable microprocessor, a microcontroller, an application-specific integrated circuit (ASIC), or other electronic circuitry capable of providing control. The controller may have a controller circuitry system that includes additional electronic components. For example, the controller circuitry system may include one or more sensors, one or more switches, one or more display elements, or any combination thereof.

[0033] The controller can be configured to activate the transfer unit only when the clamp is in the open configuration. This allows for a reduction in the risk of tearing the aerosol-generating matrix sheet by preventing movement of the aerosol-generating matrix sheet as long as the clamp is not in the open configuration.

[0034] The aerosol generation apparatus may further include an indexing unit configured to determine the position of the aerosol generation matrix sheet relative to the aerosolization element. The indexing unit may be configured to synchronize the conveying unit and the fixture based on the position of the aerosol generation matrix sheet relative to the aerosolization element. The indexing unit may be configured to activate the conveying unit in response to the position of the aerosol generation matrix sheet determined by the indexing unit.

[0035] According to a second aspect of the invention, an aerosol generation system is provided, comprising an aerosol generation apparatus according to the first aspect, and an aerosol generation matrix sheet. The aerosol generation matrix sheet may include a plurality of segments. The plurality of segments may be continuously interconnected to form the aerosol generation matrix sheet. Each joint where two consecutive segments are interconnected may be provided with a recess or orifice formed in the aerosol generation matrix sheet. The aerosol generation apparatus may include a sensor configured to detect the recess or orifice of the aerosol generation matrix sheet. The sensor may be an ultrasonic transducer. The sensor may be an optical sensor. Each segment of the aerosol generation matrix sheet may have a width and length significantly greater than the thickness of the aerosol generation matrix sheet. The aerosol generation matrix sheet may initially be wound into a cylindrical shape. The length of a segment along the direction of movement of the aerosol generation matrix sheet may correspond to the maximum size of a clamp. The length of a segment along the direction of movement of the aerosol generation matrix sheet may correspond to the maximum size of at least one aerosolizing element. In each segment, the aerosol generating matrix can have a thickness between 0.1 mm and 0.5 mm, particularly between 0.1 mm and 0.3 mm. The thickness of the aerosol generating matrix sheet in each segment can be greater than the thickness of the aerosol generating matrix sheet located at each joint between consecutive segments, particularly at least 10%, particularly 50%.

[0036] According to a third aspect of the invention, a method for operating an aerosol generating apparatus is provided, comprising the steps of: (A) moving a clamp to a closed configuration to clamp an aerosol generating matrix sheet; (B) activating an aerosolization element to aerosolize the aerosol generating matrix sheet; (C) moving the clamp to an open configuration to release the aerosol generating matrix sheet; and (D) after step (C), moving the aerosol generating matrix sheet through the clamp a predefined distance. The predefined distance may be at least equal to the length of the aerosolization element in the direction of movement of the aerosol generating matrix sheet. The length of the aerosolization element may be the maximum dimension of the aerosolization element projected onto the plane of the aerosol generating matrix sheet. Step (A) or step (B) of the method may be triggered by detecting inhalation by a consumer. The method may include a step of deactivating at least one aerosolization element between step (B) and step (C). When the aerosolization element is deactivated, the aerosolization element may not consume energy. The step of deactivating at least one aerosol generating element can be triggered after a predefined delay from the activation of at least one aerosol generating element in step (B). The step of deactivating at least one aerosol generating element can be triggered by detecting a pressure drop. The detection of the pressure drop can be performed by means of a flow sensor connected to the controller of the aerosol generating device. Step (C) can be performed after a predefined delay from the detection of the pressure drop, particularly less than 10 seconds after the detection of the pressure drop. Alternatively or in combination, step (C) can be performed after a predefined pressure threshold is detected. Upon the next detection of consumer inhalation, step (D) can be followed by a new cycle of steps (A) to (D). The movements performed in steps (A), (C), and (D) can be actuated by means of a common rotary motor of the aerosol generating device. The movements performed in steps (A), (C), and (D) can be mechanically decoupled from each other, particularly by means of the freewheel assembly of the aerosol generating device.

[0037] According to a fourth aspect of the invention, a clamp in an aerosol generation apparatus is provided for restricting the movement of an aerosol generation matrix sheet through the clamp to keep the aerosol generation matrix sheet stationary during aerosol generation from the aerosol generation matrix sheet.

[0038] According to a fifth aspect of the invention, an aerosol generating apparatus is provided, comprising: at least one aerosolizing element configured to generate an aerosol from an aerosol generating matrix sheet; a conveying unit configured to move the aerosol generating matrix sheet relative to the aerosolizing element; and an indexing unit configured to determine the position of the aerosol generating matrix sheet relative to the aerosolizing element; wherein the indexing unit is coupled to the conveying unit such that after the indexing unit has determined that the aerosol generating matrix sheet has moved a predefined distance, the movement of the aerosol generating matrix sheet relative to the aerosolizing element is stopped. The indexing unit may be configured to aerosolize the same portion of the aerosol generating matrix sheet only once. The conveying unit may be driven by at least one motor, particularly an electric motor, and more particularly a rotary motor. The predefined distance may be limited such that the amount of aerosol generated provides a sufficient amount of inhalable aerosol to a consumer for a single inhalation.

[0039] The predefined distance is at least equal to the length of the aerosolization element in the direction of movement of the aerosol-generating matrix sheet. The predefined distance can be the minimum distance required to avoid heating the same portion of the aerosol-generating matrix sheet more than once. The predefined distance can be greater than the length of the aerosolization element. The predefined distance can be between 5 mm and 20 mm, particularly between 8 mm and 15 mm, and more particularly between 9 mm and 12 mm. The value of the predefined distance can be adjusted using the controller of the aerosol-generating device.

[0040] Indexing units can be connected to at least one aerosolization element for sequentially aerosolizing aerosol-generating matrix sheet.

[0041] The indexing unit can be configured to activate at least one aerosolization element after the indexing unit determines that the aerosol generation matrix sheet has moved a predefined distance. At least one aerosolization element can be configured to be activated only for aerosol generation (i.e., only when the aerosol generation device is required). The energy consumption of the aerosol generation device can be reduced by activating at least one aerosolization element only when the indexing unit determines that the aerosol generation matrix sheet has moved a predefined distance.

[0042] The conveying unit may include at least one drive element configured to move the aerosol-generating matrix sheet, and the indexing unit may be configured to detect the position of the at least one drive element. The drive element may include at least one roller. The indexing unit may be configured to detect the position of the at least one roller, particularly the angular position of the at least one roller. The conveying unit may include a first pair of rollers arranged upstream of the aerosol-generating matrix sheet relative to the conveying direction of the aerosol-generating matrix sheet. The conveying unit may also include a second pair of rollers arranged downstream of the aerosol-generating matrix sheet relative to the conveying direction of the aerosol-generating matrix sheet.

[0043] The indexing unit may include an encoder assembly. The encoder assembly may be configured to detect the angular position of at least one roller with an accuracy of less than 1 degree, particularly less than 0.5 degrees, and more particularly less than 0.3 degrees.

[0044] The encoder assembly may include a Hall sensor. A Hall sensor can be activated by the presence of an external magnetic field.

[0045] The aerosol generation apparatus may further include a clamp configured to hold and release an aerosol generation matrix sheet, and a transfer unit configured to move the aerosol generation matrix sheet relative to at least one aerosolizing element through the clamp. The clamp may have: a closed configuration in which movement of the aerosol generation matrix sheet through the clamp is restricted; and an open configuration in which the transfer unit can move the aerosol generation matrix sheet through the clamp. By restricting movement of the aerosol generation matrix sheet through the clamp, the aerosol generation matrix sheet can be kept stationary during aerosol generation. Undesirable or unintentional displacement of the aerosol generation matrix sheet can be advantageously prevented in the closed configuration. The aerosol generation matrix sheet can be held relative to at least one aerosolizing element. In particular, at least one aerosolizing element remains stationary relative to the aerosol generation matrix sheet during aspiration. Therefore, it allows a portion of the matrix to undergo aerosolization more thoroughly, so as to aerosolize most of the aerosolizable contents of the matrix during aspiration.

[0046] The indexing unit may include a first position mark and a second position mark, the first position mark indicating a first position corresponding to a closed configuration of the clamp, and the second position mark indicating a second position corresponding to an open configuration of the clamp. The position marks may be magnetic or optical marks. Specifically, the position marks may be one of the following: magnetoresistive marks, magneto-optical marks, retroreflective marks, and infrared reflective marks.

[0047] The transfer unit can be configured to move the aerosol-generating matrix sheet relative to the aerosolizing element only when the clamp is in the open configuration. This can allow for a reduction in the risk of tearing the aerosol-generating matrix sheet. The transfer unit can be configured to lock the movement of the aerosol-generating matrix sheet relative to the aerosolizing element in the closed configuration of the clamp. The clamp can include at least two clamping elements, wherein at least one of the clamping elements is configured to move relative to the other. In the closed configuration of the clamp, an aerosolizing chamber can be formed between the at least two clamping elements.

[0048] The encoder assembly can be configured to detect the angular position of the rotation axis of one of the at least two grippers. The encoder assembly can also be configured to detect whether the gripper is in a closed or open configuration.

[0049] The indexing unit can be activated by a sensor configured to detect the distance between the sensor and the aerosol-generating matrix sheet. Activation of the indexing unit can be independent of the angular rotation of the rollers in the conveying unit. This allows for the prevention of incorrect readings caused by slippage between the rollers and the aerosol-generating matrix sheet. The sensor can be one of an optical sensor, a magnetic sensor, a gyroscope sensor, or a capacitive sensor. The sensor can be arranged upstream of at least one aerosolization element relative to the conveying direction of the aerosol-generating matrix sheet.

[0050] The sensor can be positioned upstream of the aerosol-generating matrix sheet relative to the direction of motion of the aerosol-generating matrix sheet. The sensor can be arranged to sense portions of the aerosol-generating matrix sheet that have not yet been aerosolized by at least one aerosol-generating element.

[0051] The sensor can be an ultrasonic transducer. The ultrasonic transducer can be configured to detect recesses or openings in the aerosol generating matrix sheet. The ultrasonic transducer can be configured to use sound waves to detect the aerosol generating matrix sheet. The ultrasonic transducer can be configured to emit ultrasound and measure the duration of ultrasound return to the transducer's receiver. The ultrasonic transducer can be configured to detect the distance between the sensor and the aerosol generating matrix sheet independently of the color or transparency of the aerosol generating matrix sheet. Advantageously, the ultrasonic transducer is generally suitable for operation in dark environments, such as inside the housing of an aerosol generating device. The ultrasonic transducer can include a transceiver. By combining the transmitter and receiver in a single component, this allows for an advantageous reduction in the number of elements constituting the aerosol generating device. Alternatively, the ultrasonic transducer can include at least one transmitter and at least one receiver. At least one transmitter and at least one receiver can be arranged to face the same side of the aerosol generating matrix sheet. Alternatively, at least one transmitter and at least one receiver can be arranged to face opposite sides of the aerosol generating matrix sheet, respectively.

[0052] According to a sixth aspect of the present invention, an aerosol generation system is provided, comprising an aerosol generation apparatus according to a fifth aspect, and further comprising an aerosol generation matrix sheet.

[0053] The aerosol generating matrix sheet may include multiple segments, which are continuously interconnected to form the aerosol generating matrix sheet, and each joint connecting two consecutive segments may be provided with a recess or orifice formed in the aerosol generating matrix sheet. The aerosol generating apparatus may include a sensor configured to detect the recess or orifice of the aerosol generating matrix sheet. The sensor may be an ultrasonic transducer. Each segment of the aerosol generating matrix sheet may have a width and length significantly greater than the thickness of the aerosol generating matrix sheet. The aerosol generating matrix sheet may initially be wound into a tube shape.

Figure 2 In a non-limiting example, the clamp 202 includes two clamping elements 261, 262, wherein the first clamping element 261 is configured to move relative to the second clamping element 262. In this non-limiting example, the first clamping element 261 is arranged relative to the housing of the aerosol generating device 1000 (in... Figure 2 (Not visible in the middle) is movable, and the second clamping element 262 is relative to the housing of the aerosol generating device 1000 (as per the...). Figure 2 (The shaded area above is an illustration of a stationary position.) The conveying unit 20 is configured to move the aerosol-generating matrix sheet 31 between two clamping elements 261, 262. (As shown in the diagram above) Figure 2 As shown, in the open configuration, the two clamping elements 261, 262 are arranged sufficiently apart from each other to allow the aerosol generating matrix sheet 31 to move relative to each clamping element 261, 262.

[0324] like Figure 2 As shown, track 280 is positioned upstream of the first moving mechanism 2100 relative to the conveying direction 312. Track 280 is not positioned between rollers 210 and 211 of the first moving mechanism 2100. This allows the aerosol generation matrix sheet 31 to be conveyed through rollers 210 and 211. Track 280 is further positioned between the first moving mechanism 2100 and the clamp 202. Track 280 is not positioned between the two clamping elements 261 and 262. This allows the aerosol generation matrix sheet 31 to be clamped between the two clamping elements 261 and 262. Track 280 is further positioned between the clamp 202 and the second moving mechanism 2000. Track 280 is not positioned between rollers 208 and 209 of the second moving mechanism 2000. This allows the aerosol generation matrix sheet 31 to be conveyed through rollers 208 and 209. Finally, track 280 is positioned downstream of the second moving mechanism 2000 relative to the conveying direction 312.

[0325] exist Figure 2 In a non-limiting example, the aerosolizing element 201 is only mounted to the clamping element 262. Alternatively, each of the clamping elements 261, 262 may be provided with an aerosolizing element. The aerosolizing element 201 is provided with a plurality of segments 263 spaced apart from each other by passages 264. The aerosolizing element 201 is fluid-permeable because aerosols can pass through the passages 264 of the aerosolizing element 201. Figure 2 As shown in the example, each clamping element 261, 262 has a corresponding cavity 265. Each clamping element 261, 262 has the shape of a hollow receiving portion 268. The aerosolizing element 201 is arranged in a manner that, in the closed configuration of the clamp 202, a first side 266 of the aerosolizing element 201 is configured to contact the aerosol generating matrix sheet 311, and a second side 267 of the aerosolizing element 201, which is opposite to the first side 266 along the longitudinal direction 100, is configured to face the cavity 265 in the clamping element 262, i.e., to face the interior of the hollow receiving portion 268 of the clamping element 262. In the closed configuration of the clamp 202, an aerosolizing chamber (in) can be formed between the clamping elements 261, 262. Figure 2(Not visible in the open configuration). Specifically, the aerosolization chamber may be partially defined by the corresponding cavities 265 of the clamping elements 261, 262. When a portion 311 of the aerosol-generating matrix sheet 31 is positioned correspondingly to the aerosolization element 201, the movable clamping element 261 moves toward the aerosolization element 201 mounted to the clamping element 262. Advantageously, this ensures optimal contact between the aerosol-generating matrix sheet portion 311 and the aerosolization element 201. The direction of transport of this portion 311 of the aerosol-generating matrix sheet by means of the transport unit 20 is substantially perpendicular to the direction of movement of the clamping element 261 toward the other clamping element 262 between the closed and open configurations. The direction of movement of the clamping element 261 is substantially parallel to the longitudinal direction 100.

[0326] exist Figure 2 In a non-limiting example, the fixture 202, the first moving mechanism 2100, and the second moving mechanism 2000 are each actuated by a common motor 203. As explained below, the actuation of the fixture 202, the first moving mechanism 2100, and the second moving mechanism 2000 is mechanically decoupled from each other.

[0327] The clamp 202, particularly the clamping element 261, and the moving mechanisms 2000 and 2100 are driven by a stepping propulsion system actuated by a motor 203. The motor 203 cooperates with a first gear mechanism (not shown) configured to drive an eccentric element 207, which generates reciprocating movement of its adjacent clamping element 261. The eccentric element 207 pushes the clamping element 261 toward another clamping element 262 against the resistance of the elastic elements 212 and 213. Figure 2In this example, the elastic elements 212 and 213 are two springs 212 and 213, specifically two compression springs 212 and 213. Motor 203 actuates another corresponding gear mechanism (not shown) for driving rollers 210 and 211 of the first moving mechanism 2100 and rollers 208 and 209 of the second moving mechanism 2000 for conveying the aerosol-generating matrix sheet 31. More specifically, the conveying unit 20 includes a freewheel bearing 206 inserted between motor 203 and eccentric element 207. A first freewheel bearing 204 is arranged between motor 203 and a pair of rollers 208 and 209 of the second moving mechanism 2000. A second freewheel bearing 205 is arranged between motor 203 and a pair of rollers 210 and 211 of the first moving mechanism 2100. Freewheel bearings 204 and 205 enable decoupling of the movement of clamp 202 from the conveying of the aerosol-generating matrix sheet 31. A third freewheel bearing 206 is arranged between the motor 203 and the eccentric bearing 207. Freewheel bearings are known from the prior art. The type of freewheel selected for the aerosol generating apparatus 1000 may include a spring-loaded roller, particularly a steel roller, positioned inside the drive wheel. When rotating in one direction, the roller locks to the drive wheel, causing it to rotate uniformly. When rotating in the other direction, the roller slides only inside the drive wheel. The freewheel bearing may include a spring to ensure close contact between the roller and the drive wheel.

[0328] In the variant, the mechanical decoupling of the actuation of the clamp 202, the first moving mechanism 2100, and the second moving mechanism 2000 can be achieved by means of... Figure 2 The different configurations shown can be used to achieve this.

[0329] Figure 3 A perspective view of an aerosol generating apparatus 1000 is shown. Motor 203 is an electric motor. Motor 203 is engaged with drive wheel 214. Drive wheel 214 is coupled to a rotatable shaft 2071, which includes an eccentric element 207 corresponding to clamping element 261. A third freewheel bearing 206 is arranged at the interface between drive wheel 214 and rotatable shaft 2071. The third freewheel 206 allows the eccentric shaft 207 to be prevented from rotating backward as a portion 311 of the aerosol generating matrix sheet moves forward. Although from... Figure 3 While not visible in the image, it should be noted that the freewheel bearings 204 and 205 are arranged on their respective shafts. The third freewheel bearing 206 has the function of allowing motion transmission between the drive wheel 214 and the rotatable shaft 2071 in only one rotational direction and preventing transmission in the other rotational direction. Figure 3As shown, the eccentric element 207 abuts the bearing 216, and the clamping element base 219 is arranged in the bearing. The provision of the bearing 216 advantageously reduces the friction between the clamping element base 219 and the eccentric element 207. The rotation of the drive wheel 214 in one direction produces the reciprocating motion of the clamping element 261: upward to ensure optimal contact between the aerosol generating matrix sheet and the aerosolizing element 201, and downward to allow the aerosol generating matrix 31 to be conveyed through a pair of rollers 210, 211 and a pair of rollers 208, 209 (in Figure 3 (Not visible in the middle) and the used portion of the aerosol-generating matrix sheet is replaced by an adjacent fresh portion. The action of the eccentric element 207 on the clamping element 261 is controlled by the response of springs 212 and 213, which can be used as return springs. Springs 212 and 213 provide a flexible connection between the clamp 202 and the base 219 of the clamping element. Springs 212 and 213 also have the function of lowering the clamping element 261. Rod spring (in Figure 3 (Not visible in the middle) can ensure contact between the base 219 of the clamping element and the eccentric element 207.

[0330] Drive wheel 214 engages with gear 215, which in turn drives rollers 210 and 211 (in... Figure 3 At least one roller in (not visible in the middle). Meanwhile, drive wheel 214 engages with rollers 208, 209 configured to drive rollers 208, 209 (in the middle). Figure 3 The other gear of at least one roller (not visible in the middle) Figure 3 (Not visible in the center) The drive shaft is arranged between gear 215 and a pair of rollers 210, 211. Similarly, the drive shaft is arranged on another gear (in... Figure 3 (Not visible in the middle) between a pair of rollers 208 and 209. Freewheel bearing (in...) Figure 3 (Not visible in the image) is arranged between the gear 215 and the pair of rollers 208, 209 on the drive shaft, so as to allow the rollers 208, 209 to rotate in only one direction. Similarly, the freewheel bearing (in...) Figure 3 (Not visible in the middle) is set in a configuration on another gear (in Figure 3 (Not visible in the middle) and the drive shaft between a pair of rollers 210, 211, so as to allow rollers 210, 211 to rotate in only one direction.

[0331] exist Figure 3 In a non-limiting example, the aerosol generating apparatus 1000 may include an indexing unit 70. The indexing unit 70 may include an encoder 217. The encoder 217 is mounted on a rotatable shaft 2071 for reading its angular position. The encoder 217 is configured to send the measured angular position to a control system (not shown). The encoder 217 may be a magnetic encoder including a Hall sensor and a custom encoder ring with two magnets that provides two absolute angular positions (e.g., open and closed).

[0332] Motor 203 is activated by suction sensor assembly 103 mounted adjacent to inlet airflow channel 104. During suction, air is drawn into aerosol generating device 1000 through air inlet 105. The air then travels through aerosolization unit 60 (in... Figure 1 As shown in the diagram, an aerosol is generated at the aerosolization unit. The aerosol then leaves the aerosol generating device 1000 via exit channel 101 and is ultimately inhaled by the consumer through mouthpiece 12.

[0333] refer to Figure 4 The airflow path visibility is improved. This figure shows a cross-sectional view of the aerosol generation device 1000, with the clamp 202 in a closed configuration. The suction sensor assembly 103 includes a pressure gauge 1033 configured in fluid communication with the inlet airflow channel 104 to detect pressure changes in the inlet airflow channel 104 due to airflow associated with suction. The pressure gauge 1033 is electrically connected to a circuit board 1032 for collecting signals received from the pressure gauge 1033 and sending the signals to a controller (not shown). The controller is then configured to control the operation of the motor 203. The circuit board 1032 is mounted to the aerosolization module 2010 via a flange 1031. The aerosolization module 2010 is part of the aerosolization unit 60. (Refer to...) Figure 5 The structure of the aerosolization module 2010 is further described.

[0334] like Figure 4 As can be seen, in the closed structure of the clamp 202, an aerosolization chamber 218 is formed by the corresponding concave surfaces 265 of the clamping elements 261 and 262. Thus, in the closed structure of the clamp 202, the aerosolization chamber 218 is defined by the corresponding hollow receiving portions 268 of the clamping elements 261 and 262. In other words, the aerosolization chamber 218 is formed by two hollow receiving portions 268, wherein the hollow receiving portion 268 of the clamping element 261 is movable relative to the hollow receiving portion 268 of the clamping element 262.

[0335] During inhalation, air flows into the aerosolization chamber 218. A portion 311 of the aerosol generation matrix sheet 21 is aerosolized by means of the aerosolization element 201 and generates an aerosol in the aerosolization chamber 18. The generated aerosol then flows to the outside of the aerosolization chamber 218 via the exit channel 101 and exits through the mouthpiece 12 for inhalation.

[0336] Figure 5 Different parts of the aerosolization module 2010 of the aerosol generation device 1000 are shown. On the left, Figure 5The top portion of the aerosolization module 2010 is shown, which includes at least a clamping element 262, an aerosolization element 201 mounted on the clamping element 262, and a flange 1031. The aerosolization element 201 is disposed in the hollow receiving portion 268 of the clamping element 262. The aerosolization element 201 may be an electric heater 201. The aerosolization element 201 includes multiple segments 263, particularly arranged as... Figure 5 The non-limiting example shows a serpentine-shaped wound conductor. Parallel conductor segments 263 can be spaced apart from each other by a distance between 0.1 mm and 0.8 mm, thereby forming a passage 264. Thus, the aerosol generated by the electric heater 201 can pass through the passage 264.

[0337] exist Figure 5 In a non-limiting example, the aerosolizing element 201 is removably attached to the hollow receiving portion 268 of the clamping element 262 by means of fasteners.

[0338] exist Figure 5 In a non-limiting example, the first side 266 of the aerosolizing element 201 is planar. The outer surface 269 of the periphery 2091 of the hollow receiving portion 268 extends in the same plane as the first side 266 of the aerosolizing element 201. This allows the aerosolizing module 2010 to be more compact and improves the surface contact area between the segment 263 of the aerosolizing element 201 and the aerosol generating matrix sheet in the closed configuration of the fixture 202.

[0339] on the right, Figure 5 The bottom portion of the aerosolization module 2010 is shown, which includes a clamping element 261. Figure 5In a non-limiting example, clamping element 261 has a different construction than clamping element 262. Clamping element 261 is formed by a support structure (such as a hollow receiving portion 268) having a cavity 265. The support structure 268 may have a length and width in a first plane 269, and a height 273 perpendicular to the first plane 269, with the length and width being greater than the height 273. The hollow receiving portion 268 is generally square in the first plane 269. The cavity 265 is centrally located in the support structure 268. The cavity 265 extends along the height 273 from the first plane 269 to a second plane 274. The second plane 274 is parallel to the first plane 269. The first plane 269 defines the opening of the cavity 265. The second plane 274 defines the bottom of the cavity 265. The second plane 274 is substantially flat. The cavity 265 is defined by a lateral wall connecting the first plane 269 to the second plane 274. The lateral walls are substantially inclined relative to the height 243 of the hollow receiving portion 268. In this non-limiting example, the inclination of the lateral walls is less than 60 degrees. In particular, the bottom of the cavity 265 has a surface smaller than the orifice of the cavity 265 in the first plane. The hollow receiving portion 268 has a periphery 2090 surrounding the cavity 265 of the hollow receiving portion 268. The outer surface 269 of the periphery 2090 may extend in the first plane 269 and is thereby defined by common reference numeral 269. A clamping element 261 may be included along the periphery 2090 (in Figure 5 The sealing element 2021 (indicated by the dashed line) is such as a silicone rubber joint 2021. In the closed configuration of the clamp 202, the periphery 2090 of the clamping element 261 is configured to contact a portion 311 of the aerosol generating matrix sheet 31. This allows for ensuring tight contact between the aerosol generating matrix sheet and the aerosolization element 201 mounted on another clamping element 262. The sealing element 2021 can reduce heat loss from the aerosolization chamber 218 in the closed configuration. Advantageously, this can ensure a satisfactory suction resistance (RTD) level. Alternatively, the periphery 2090 of the clamping element 261 may not have any sealing element. This can reduce the friction between the aerosol generating matrix sheet and the periphery 2090, which is advantageous for moving the aerosol generating matrix sheet. Figure 5 As shown, the hollow receiving portion 268 of the clamping element 261 is mounted on the support member 275. The support member 275 extends substantially laterally from the first plane 269 and the second plane 274. The support member 275 is configured to interact with the bearing 216 and the springs 213, 214 (in... Figure 2 (As can be seen) their interaction, especially their mechanical connection.

[0340] As mentioned above Figure 5Each hollow receiving portion 268 of the clamping elements 261, 262 includes a corresponding periphery 2090, 2091. The corresponding peripheries 2090, 2091 of the hollow receiving portions 268 are configured to face each other to form an aerosolization chamber 218. The hollow receiving portion 268 of each of the clamping elements 261, 262 may be electrically insulating. Each hollow receiving portion 268 may have a thermal conductivity of 1 watt / (m·Kelvin) or less.

[0341] Advantageously, the clamping element 261 is formed in a way that ensures close contact between a portion 311 of the aerosol-generating matrix sheet and the aerosolization element 201, while simultaneously limiting heat loss. This is achieved through the concave surface 265 of the clamping element 261 (defining the hollow receiving portion 268) and the fact that the clamping element 261 is configured to clamp only this portion 311 of the aerosol-generating matrix sheet corresponding to the periphery 2090 of the clamping element 261. In this way, it is ensured that almost all the power delivered by the aerosolization element 201 is actually received by this portion 311 of the aerosol-generating matrix sheet for aerosolization. This can allow for improved aerosolization efficiency of the aerosol generation apparatus 1000.

[0342] The width of this portion 311 of the aerosol-generating matrix sheet can be substantially equal to the width of the aerosolizing element 201. This allows ensuring that, in a closed configuration, the entire portion 311 of the aerosol-generating matrix sheet positioned within the aerosolizing chamber 218 receives energy, such as heat, generated by the aerosolizing element 201. The periphery 2090 of the clamping element 261 can define a region that matches this portion 311 of the aerosol-generating matrix sheet that comes into contact with the aerosolizing element 201 during aspiration for aerosolization. The width of this portion of the aerosol-generating matrix sheet 311 can be smaller than the width of the clamping element 261 to allow airflow in and out. The width of this portion of the aerosol-generating matrix sheet 311 can be smaller than the width of the sealing element 2021 to prevent airflow from collecting the generated aerosol.

[0343] Figures 6 to 11 The sequential steps of a method for operating the aerosol generating apparatus 1000 are shown. See below for further details. Figures 6 to 11 In further detail, the method includes the steps of moving the clamp 202 into a closed configuration to clamp the aerosol generation matrix sheet 31, activating the aerosolization element 201 to aerosolize the clamping portion 311 of the aerosol generation matrix sheet, moving the clamp 202 into an open configuration to release the aerosol generation matrix sheet 31, and then moving the aerosol generation matrix sheet 31 through a predefined distance by the clamp 32.

[0344] Figure 6The configuration of the device 1000 before and during inhalation is shown. The clamp 202 is in a closed configuration, such that the clamping portion 311 of the aerosol-generating matrix sheet is firmly contacted against the aerosolizing element 201. This is achieved by means of springs 212, 213 (in... Figure 2 , 3 (As shown in Figure 4) The clamping element 261 is pushed against the clamping element 262 to secure it. In the closed configuration, springs 212, 213 bring the eccentric element 207 into contact with the bearing 216 arranged around the base 219 of the clamping element. When the consumer applies negative pressure to the mouthpiece 12 (i.e., by inhaling), the inhalation sensor assembly 103 detects the inlet airflow channel 104 and sends a signal to the controller (not shown). The controller then activates the aerosolization element 201 to aerosolize the clamping portion 311 of the aerosol-generating matrix sheet. The rollers 208, 209, 210, 211 of the conveying unit 20 do not move, and the clamp 202 remains in the closed configuration.

[0345] When aspiration is nearing completion, or when the inlet airflow pressure drop on the aspiration sensor assembly 103 decreases below a threshold defined for aspiration initiation, the aerosolization element 201 is deactivated by a controller that sequentially activates the delivery unit 20 to first open the clamp 202 and then advance the aerosol generation matrix sheet 31 to align its fresh portion with the aerosolization element 201 for the next aspiration. If necessary, a delay of up to several seconds (e.g., 10 seconds) can be applied before opening the clamp 202 after aspiration ends. Preferably, aerosolization initiation can occur slightly earlier than aspiration termination to ensure that all generated aerosol is aspirated by the consumer. This allows aerosol residue in the airflow channel 104 to be avoided, which could lead to condensation.

[0346] Figure 7 The diagram illustrates the steps of a method in which a controller triggers clockwise rotation of a motor 203, which engages a drive wheel 214, thereby producing counterclockwise motion. A freewheel bearing 206 associated with a rotatable shaft including an eccentric element 207 is configured to allow torque transmission, thus rotating the eccentric element 207 counterclockwise and lowering clamping element 261 relative to another clamping element 262. The drive wheel 214 simultaneously drives gears 215 and 245 clockwise, which are respectively coupled to a pair of rollers 208, 209 and a pair of rollers 210, 211. More specifically, gear 215 is configured to drive a lower roller 209, which in turn drags an upper roller 208 by friction. Similarly, gear 245 is configured to drive a lower roller 211, which in turn drags an upper roller 210 by friction. However, when gears 215 and 245 rotate clockwise, the free wheel bearings 204 and 205, respectively located on the transmission shaft between gears 215 and 245 and lower rollers 209 and 211, stop rotating. Figure 2 (As shown in the diagram) It is configured to act as a standard bearing, transmitting almost no torque to the lower rollers 209 and 211. The overall result is that the clamp 202 opens while the aerosol-generating matrix sheet 31 remains stationary relative to the aerosolization element 201.

[0347] Figure 8 The clamp 202 is shown at the end of its stroke, where the drive wheel 214 has completed a 180° counterclockwise rotation. At this point, once the open configuration of the clamp 202 is detected, particularly by means of the encoder 217, the motor 203 stops rotating.

[0348] Figure 9 The clamp 202 is shown in the open configuration, thus releasing the aerosol-generating matrix sheet 31. The transfer unit 20 is activated, and the aerosol-generating matrix sheet 31 can now be unwound (in... Figure 1 The tube (shown in the diagram) propels the aerosol generating matrix sheet 31. The aerosol generating matrix sheet 31 moves through the clamp 202 a predefined distance 272. The predefined distance 272 is at least equal to the length of the aerosolizing element 201 in the direction 312 of the aerosol generating matrix sheet 31's transport. The predefined distance 272 may be at least equal to the maximum dimension of the hollow receiving portion 268 in the first plane. This allows the same portion of the aerosol generating matrix sheet 31 to be aerosolized more than once. The controller is configured to activate the transport unit 20 between consecutive consumer inhalations. The controller is configured to activate the transport unit 20 only when the clamp 202 is in the open configuration. This allows the aerosol generating matrix sheet 31 to be torn. After a defined delay (e.g., 0.5 seconds), the motor 203 rotates in the opposite direction (i.e., counterclockwise). Therefore, the drive wheel 214 rotates clockwise, causing... Figure 9 The freewheel bearing 206 in the conveyor unit 20 does not transmit torque to the eccentric element 207, which thus remains stationary. Instead, the counterclockwise rotation of gears 215 and 245 transmits torque to rollers 209 and 211, respectively. As a result, the rotation of rollers 208, 209; 210, 211 generates linear motion of the aerosol-generating matrix sheet 31 via friction. By using silicone on the contact surfaces of rollers 208, 209; 210, 211 to increase friction with the aerosol-generating matrix sheet 31, motion is ensured to be transmitted to the aerosol-generating matrix sheet 31 without slippage. In addition, the upper rollers 208, 210 of the conveyor unit 20 are subjected to a downward force, particularly a force of 1.5 Newtons, via corresponding springs 270 and 271, to ensure good contact with the aerosol-generating matrix sheet 31. At the end of the conveying of the aerosol generating matrix sheet 31, especially after the predefined displacement distance 272, the fresh portion 311 of the aerosol generating matrix sheet is displaced correspondingly to the aerosolization element 201.

[0349] Figure 10It shows Figure 9 Then, after a predefined delay (e.g., 0.5 seconds), the aerosol generating apparatus 1000 is in a state where the motor 203 rotates in the opposite direction to close the clamp 202. Therefore, the clamping element 261 is pushed toward the clamping element 262. Thus, in the closed configuration of the clamp 202, surface contact is established between the fresh portion 311 of the aerosol generating matrix sheet and the aerosolizing element 201. This surface contact between the aerosol generating matrix sheet 31 and the aerosolizing element 201 is particularly advantageous when the aerosolizing element 201 is a heater (e.g., an electric heater). This allows for improved heat transfer from the aerosolizing element 201 to that portion 311 of the aerosol generating matrix sheet. The rotation direction of the motor 203 is opposite to that of the clamping element 262. Figure 7 The initial method steps shown are the same (i.e., clockwise), wherein the freewheel bearing 206 transmits torque to the eccentric element 207, which rotates to impart upward movement to the clamping element 261. Freewheel bearings 204 and 205, respectively connected to the lower rollers 209 and 211 (in... Figure 2 (As shown in the diagram) is configured to act as a standard bearing, meaning it transmits almost no torque to the lower rollers 209 and 211. Therefore, Figure 10 The aerosol generating matrix sheet 31 remains stationary relative to the aerosolizing element 201.

[0350] Figure 11 An aerosol generating apparatus 1000 is shown with a clamp 202 in a closed configuration, wherein a fresh portion 311 of the aerosol generating matrix sheet is arranged against the aerosolizing element 201. Once the closed configuration of the clamp 202 is detected by means of an encoder 217 reading the angular position of the associated rotatable shaft, the motor 203 stops rotating. Figure 11 Then, the fresh portion of the aerosol generating matrix sheet 31 is placed against the aerosol generating element 201, and the aerosol generating device 1000 is ready for the next suction.

[0351] Therefore, the aerosol generation apparatus 1000 relates to a synchronization system including a transfer unit 20 for moving the aerosol generation matrix sheet 31 through a clamp 202. The clamp 202 ensures optimal contact between the aerosolization element 201 and the portion 311 of the aerosol generation matrix sheet 31 to be aerosolized.

[0352] Figure 12 Another aerosol generating device 1010 is shown schematically and in part. Elements with the same reference numerals as those described and shown in the preceding figures will not be described in detail again, but will be referred to in the above description.

[0353] Similar to aerosol generating apparatus 1000, aerosol generating apparatus 1010 includes an outer housing (not shown) housing a gas flow unit (not shown), a delivery unit 20, and an aerosolization unit 60. Optionally, as described with respect to aerosol generating apparatus 1000, aerosol generating apparatus 1010 may be provided with a first compartment and a second compartment. Aerosol generating apparatus 1010 may include a power source (not shown), such as a battery, for supplying power to one or more of the units 10, 20, 30, 40, and 60. Aerosol generating apparatus 1010 may include at least one controller (not shown) electrically connected to one or more of the units 10, 20, 30, 40, and 60.

[0354] The aerosol generating apparatus 1010 includes an aerosolization chamber 218. The aerosolization chamber 218 is at least partially defined by a hollow receiving portion 268. The hollow receiving portion 268 includes a cavity 265. A conveying unit 20 is configured to move a portion 311 of the aerosol generating matrix sheet 31 relative to the hollow receiving portion 268. The aerosol generating apparatus 1010 includes an aerosolization element 201 configured to aerosolize the portion 311 of the aerosol generating matrix sheet 31. The aerosolization element 201 is disposed in the aerosolization chamber 218. A first side 266 of the aerosolization element 201 is configured to face the aerosol generating matrix sheet 311. A second side 267 of the aerosolization element 201, opposite to the first side 266, is configured to face the interior of the hollow receiving portion 268. Figure 12 In a non-limiting example, the aerosolizing element 201 is an electric heater 201, particularly a planar electric heater 201. The aerosolizing element 201 is provided with a plurality of segments 263 spaced apart from each other by passages 264. Since the electric heater 201 is planar, the plurality of segments 263 are adapted to make surface contact with portions 311 of the aerosol-generating matrix sheet 31. The aerosolizing element 201 is fluid-permeable because aerosol 1013 can pass through the passages 264 of the aerosolizing element 201.

[0355] exist Figure 12 In a non-limiting example, the conveying unit 20 includes a moving mechanism equipped with tension rollers 1011 and 1012. The first tension roller 1011 is arranged upstream of the aerosolizing element 201 relative to the conveying direction 312. The second tension roller 1012 is arranged downstream of the aerosolizing element 201 relative to the conveying direction 312. The tension rollers 1011 and 1012 are respectively configured to adjust the portion 311 of the aerosol-generating matrix sheet 31 relative to the aerosolizing element 201. Specifically, as... Figure 12As shown, tension rollers 1011 and 1012 are respectively configured to bring a portion 311 of the aerosol-generating matrix sheet 31 into surface contact with a first side 266 of the aerosolizing element 201. Alternatively, the conveying unit 20 may include a first pair of friction rollers arranged upstream of the aerosolizing element 201. Alternatively or in combination, the conveying unit 20 may include a second pair of friction rollers arranged downstream of the aerosolizing element 201.

[0356] The aerosol generation chamber 218 of the aerosol generation device 1010 includes an air inlet 1014 and an air outlet 1015, which are defined by recesses 1014 and 1015 respectively provided in the hollow receiving portion 268. Each recess 1014 and 1015 extends perpendicularly from the outer surface 269 of the periphery 2091 of the hollow receiving portion 268 relative to the longitudinal direction 100.

[0357] The difference between aerosol generating apparatus 1010 and aerosol generating apparatus 1000 is that the aerosolization unit 60 may not have the clamp 202. Aerosol generating apparatus 1010 may not include any clamping elements 261, 262. Therefore, aerosol generating apparatus 1010 can provide a simpler structure for aerosol generating apparatus. The hollow accommodating portion 268 of aerosol generating apparatus 1010 can be arranged immovably relative to the outer casing (not shown) of aerosol generating apparatus 1010.

[0358] In the illustrated example, the aerosol generating apparatus 1010 differs from the aerosol generating apparatus 1000 in that the aerosolization chamber 218 is defined by one hollow accommodating portion 268 instead of two hollow accommodating portions in the aerosol generating apparatus 1000. However, the number of hollow accommodating portions defining the aerosolization chamber is not limiting. When the aerosolization unit includes two or more hollow accommodating portions, the number of hollow accommodating portions on which aerosolization elements are respectively provided is also not limiting.

[0359] A method for operating the aerosol generating apparatus 1010 to generate an inhalable aerosol includes: moving an aerosol generating matrix sheet 31 such that a segment 311 (i.e. a portion) of the aerosol generating matrix sheet 31 faces the hollow receiving portion 268; and activating an aerosolizing element 201 facing the hollow receiving portion 268 to generate an inhalable aerosol 1013 from the portion 311 of the aerosol generating matrix sheet 31 in the hollow receiving portion 268, particularly in the aerosolizing chamber 218.

[0360] Figure 13 Another aerosol generating device 1020 is shown schematically and in part. Elements with the same reference numerals as those described and shown in the preceding figures will not be described in detail again, but will be referred to in the above description.

[0361] Similar to aerosol generating apparatus 1000, aerosol generating apparatus 1020 may include an outer housing 50 having an airflow unit 10 and a mouthpiece 12. Aerosol generating apparatus 1020 includes an aerosolization element (not shown) configured to generate aerosols from an aerosol generating matrix sheet (not shown). The aerosolization element is disposed in an aerosolization unit 60 of aerosol generating apparatus 1020. The aerosolization element may be the same as the aerosolization element 201 described with respect to aerosol generating apparatus 1000, and reference is made to said aerosolization element. Aerosol generating apparatus 1020 includes a conveying unit 20 configured to move the aerosol generating matrix sheet relative to the aerosolization element. The conveying unit 20 of aerosol generating apparatus 1020 may be the same as the conveying unit 20 described with reference to aerosol generating apparatus 1000 or 1010. Aerosol generating apparatus 1020 may be provided with a first storage compartment 30 and a second waste compartment 40. As described with reference to the aerosol generating apparatus 1000, the second waste compartment 40 may be connected to a conduit 41 configured to transport the aerosol generating matrix sheet toward the second waste compartment 40.

[0362] The aerosol generating apparatus 1020 includes an indexing unit 70 configured to determine the position of an aerosol generating matrix sheet relative to an aerosolizing element. The indexing unit 70 is coupled to the conveying unit 20 such that after the indexing unit 70 determines that the aerosol generating matrix sheet has moved a predetermined distance, the movement of the aerosol generating matrix sheet relative to the aerosolizing element is stopped.

[0363] The aerosol generating device 1020 may include a power source (not shown), such as a battery, for supplying power to one or more of the units 10, 20, 30, 40, 60, 70. The aerosol generating device 1020 may include at least one controller electrically connected to one or more of the units 10, 20, 30, 40, 60, 70.

[0364] The difference between aerosol generating apparatus 1020 and aerosol generating apparatus 1000 lies in the fact that the aerosolization unit 60 of aerosol generating apparatus 1020 may not have the clamp 202. Aerosol generating apparatus 1020 may not include any clamping elements 261, 262. Therefore, aerosol generating apparatus 1020 can provide a simpler structure for aerosol generating apparatus.

[0365] A method for advancing an aerosol generation matrix sheet in an aerosol generation apparatus 1020 includes: determining the position of the aerosol generation matrix sheet relative to an aerosolization element of an aerosolization unit 60, moving the aerosol generation matrix sheet relative to the aerosolization element a predetermined distance according to the determined position, and stopping the movement of the aerosol generation matrix sheet after moving the aerosol generation matrix sheet a predetermined distance.

[0366] Figure 14 A front cross-sectional view of another aerosol generating device 3000 is shown. Elements with the same reference numerals as described and shown in the preceding figures will not be described in detail again, but will be referred to in the preceding description.

[0367] The aerosol generating device 3000 includes a housing 3001. The aerosol generating device 3000 includes a power source 3020, such as a rechargeable battery. The battery 3020 is rechargeable via a charging port 3002. The housing 3001 is provided with a mouthpiece 3003 for inhalation by a consumer. The mouthpiece 3003 can be detachably mounted to the housing 3001. This allows for replacement of the mouthpiece 3003. The housing 3001 is provided with at least one recess 3004. Figure 14 As shown, a recess 3004 may be provided on a lateral side 3005 of the housing 3001. The recess 3004 extends from a first plane of the lateral side 3005 to a second plane. The first plane is parallel to the second plane. The second plane forms the bottom 3015 of the recess 3004. The bottom of the recess 3004 is substantially flat. The depth of the recess 3004 corresponds to the distance between the first plane and the second plane. The depth of the recess 3004 may be between 5 mm and 50 mm, particularly between 10 mm and 30 mm.

[0368] The aerosol generating apparatus 3000 includes an aerosolization unit 3006. For example... Figure 14 As shown, the aerosol generation unit 3006 protrudes from the base of the recess 3004. Specifically, the aerosol generation unit 3006 may not protrude beyond the lateral sidewall 3005 of the housing 3001. The aerosol generation unit 3006 includes a clamp 202 formed by two clamping elements 3021, 3022. The clamp 202 of the aerosol generation apparatus 3000 may include the same clamping elements 261, 262 as those in the aerosol generation apparatus 1000. However, in… Figure 14 In a non-limiting example, clamp 202 includes two identical clamping elements 3021, 3022. Therefore, the subsequent description relating to one of the clamping elements (3021, 3022) also applies to the other clamping element (3021, 3022).

[0369] Figure 15 An exploded view of the clamping element 3021 is shown on the left, and a view of the clamping element 2021 in its assembled configuration is shown on the right.

[0370] The clamping element 3021 is formed by a support structure (e.g., a hollow receiving portion 268) provided with a cavity 265. The support structure 268 may have a length and a width in a first plane 269, and a height 273 perpendicular to the first plane 269, the length and the width being greater than the height 273. The hollow receiving portion 268 is generally square in the first plane 269. The cavity 265 extends along the height 273 from the first plane 269 until a second plane 274. The second plane 274 is parallel to the first plane 269. The first plane 269 defines the aperture of the cavity 265. The second plane 274 defines the bottom 274 of the cavity 265. The bottom 274 of the cavity is substantially flat. The cavity 265 is bounded by side walls 276 connecting the first plane 269 to the second plane 274. In the non-limiting example shown, the side walls 276 are substantially perpendicular to the second plane 274. Thus, the bottom 274 of the cavity 265 has a surface substantially the same as the aperture of the cavity 265 in the first plane 269. The hollow receiving portion 268 has a periphery 2090 of the cavity 265 surrounding the hollow receiving portion 268. The outer surface 269 of the periphery 2090 may extend in the first plane 269 and is thus defined by the common reference numeral 269.

[0371] The clamping element 3021 further includes an atomization element 201. The atomization element 261 is a heating element 201. As Figure 15 shown on the right side of, the heating element 201 is parallel to the first plane 269. The heating element 261 includes a plurality of heating segments 263 and at least one attachment portion 275. In the Figure 15 non-limiting example shown, the heating element 201 includes four attachment portions 275. In the Figure 15In the non-limiting example shown, a plurality of heating segments 263 and at least one attachment portion 275 are integrally formed and comprise stainless steel. Advantageously, this simplifies manufacturing and improves the robustness of the heating element 201. The heating element 201 includes at least a first electrical contact 276 and a second electrical contact 277. The first electrical contact 276 is attached to a first end of the heating element 201. The second electrical contact 277 is attached to a second end of the heating element 201. A serpentine continuous electrical path is formed between the first electrical contact 276 and the second electrical contact 277 in the heating element 201. This continuous electrical path has a total resistance of approximately 1 ohm. A portion of the heating element 201 covers the opening of the cavity 265. In particular, each heating segment of the heating segments 263 covers the opening of the cavity 265. The first electrical contact 276 and the second electrical contact 277 respectively cover the lateral outer wall 278 of the hollow receiving portion 268 to allow electrical connection to external electronic devices. The attachment portions 275 are each attached to the hollow receiving portion 268 via a press-fit connection in a corresponding recess 279 of the hollow receiving portion 268. Alternatively or in combination, the attachment portions 275 may be attached to the hollow receiving portion 268 via a snap-fit ​​connection or by means of fastener elements. In this non-limiting example, the heating element 201 is not coated; however, the heating element 201 may be coated with a thin layer of corrosion-resistant material to extend the life of the clamping element 3021. Examples of such materials are ceramic materials. The resistance of each heating segment 263 may be higher than the resistance of each attachment portion 275. The aerosolizing element 201 is provided with a plurality of segments 263 spaced apart from each other by passages 264. The aerosolizing element 201 is fluid-permeable because aerosols can pass through the passages 264 of the aerosolizing element 201. When projected onto the first plane 269, the heating element 201 has a serpentine shape. Advantageously, this arrangement allows for the arrangement or filling of numerous heating segments 263 within a reduced area.

[0372] In another example (not shown), at least a portion of the heating element 201 may be coplanar with the first plane 269 of the hollow receiving portion 268. Multiple segments 263 may be substantially coplanar with the first plane 269 of the hollow receiving portion 268. The shape of the heating element 201 in the first plane 269 may be serpentine.

[0373] The hollow receiving portion 268 also includes three air inlets 281 and three air outlets 282 defined by recesses provided in the hollow receiving portion 268. The corresponding number of air inlets and air outlets is not limiting. The number of air inlets may differ from the number of air outlets. The depth of each recess 281, 282 extends perpendicularly from the first plane 169. Each recess 281, 282 extends from the inner lateral wall 276 of the hollow receiving portion 282 to the outer lateral wall 278. Each air inlet 281 is aligned with an air outlet 282. In the assembly configuration of the clamping element 3021, as... Figure 15 As shown on the right, air inlets 281 and 282 allow fluid communication between cavity 265 and the outside of clamping element 3021. Air inlets 281 and 282 are disposed on two opposing outer walls 278 of the hollow receiving portion 268. A first contact pad 283 and a second contact pad 284 are respectively disposed on the two different opposing outer walls 278 of the hollow receiving portion 268. Each contact pad 283, 284 extends vertically from the outer wall 278 of the hollow receiving portion 268 along its respective height. Each contact pad 283, 284 has a substantially straight cylindrical shape. The transverse cross-section of the first contact pad 283 is larger than that of the second contact pad 284. The contact pads 283 and 284 have substantially the same height. (The text abruptly ends here, likely due to an incomplete translation or missing information.) Figure 19 Further described, the first contact pad 283 of the hollow receiving portion 268 is configured to form a shape-fitting connection with the elastic mechanism.

[0374] return Figure 14 In this non-limiting example, each clamping element 3021, 3022 is provided with a corresponding aerosolization element 261. This allows for heating of both sides of the aerosol-generating matrix sheet. In another example (not shown), only one of the two clamping elements 3021, 3022 may be provided with an aerosolization element 261. Figure 14 In the illustrated example, clamping elements 3021 and 3022 can move from the open configuration of clamp 202 to the closed configuration of clamp 202 by means of an elastic mechanism 3007. The elastic mechanism 3007 can be a spring, particularly a compression spring or a torsion spring. Figure 14 In the illustrated example, actuator 3008 is configured to actuate clamping element 3021. Actuator 3008 may be driven by gear mechanism 3009. Gear mechanism 3009 may include components related to the referenced... Figure 2 The gear shown is similar to the gear described. When the elastic mechanism 3007 mechanically connects the clamping elements 3021 and 3022, the relative movement between the two clamping elements 3021 and 3022 is driven by a common actuator 3008. (Reference) Figure 19 The elastic mechanism 3007 is further described. The clamp 3022 can be moved from a closed configuration suitable for aerosolization of the aerosol generating matrix to an open configuration that allows the aerosol generating matrix to be transferred between the clamping elements 3021, 3022.

[0375] The recess 3004 of the aerosol generating apparatus 3000 is further provided with actuators 3010 and 3011, which are configured to drive the aerosol generating matrix sheet or a moving mechanism of the aerosol generating article including the aerosol generating matrix sheet. The aerosolization unit 3006 is arranged between the two actuators 3010 and 3011. Figure 14In a non-limiting example, the actuators 3010 and 3011 are roller actuators. The aerosolization unit 3006 and the actuators 3010 and 3011 are arranged in a first recessed region 3012 of the recess 3004. The first recessed region 3012 connects a second recessed region 3013 and a third recessed region 3014. In a first plane of the lateral side 3005, the first recessed region 3012 is substantially rectangular in shape. In the first plane of the lateral side 3005, the second recessed region 3013 may be substantially rectangular, oval, or circular in shape. In the first plane of the lateral side 3005, the third recessed region 3014 is substantially rectangular in shape. The recess 3004, particularly its recessed regions 3012, 3013, and 3014, defines a receiving portion 3004 configured to receive an aerosol-generating article 4000. (See reference...) Figure 16 Further description of aerosol-generated product 4000.

[0376] like Figure 14 As shown, at least one hinge support 3015 may be provided on the lateral side 3005 of the housing 3001. The hinge support 3015 can be used to pivotally mount a closure element (not shown) to the housing 3001. The closure element can be configured to reversibly close the receiving portion 3004. The closure element of the aerosol generating device 3000 can be pivoted to an open position to allow the aerosol generating article 4000 to be inserted into the receiving portion 3004. Then, once the aerosol generating article 4000 is received inside the aerosol generating device 3000, the closure element of the aerosol generating device 3000 can be closed. Therefore, once the closure element is closed, the consumer may not be able to directly access the aerosol generating article 4000. The aerosol generating article 4000 can be replaced. The aerosol generating device 3000 can be reusable.

[0377] Figure 16A transparent view is shown of an aerosol generating article 4000 for use with an aerosol generating apparatus 3000. The aerosol generating article 4000 includes a housing 4001. The housing 4001 includes an aerosol generating matrix sheet 31. The housing 4001 of the aerosol generating article 4000 is a substantially enclosed housing 4001 configured to hold the aerosol generating matrix sheet 31 within the housing 4001. More precisely, the housing 4001 includes a first compartment 4002 and a second compartment 4003 for receiving at least a portion of the aerosol generating matrix sheet 31, respectively. The aerosol generating matrix sheet 31 can be stored as a tube in the first compartment 4002. Similar to the first compartment 30 of the aerosol generating article 1000, the first compartment 4002 may be provided with a circular pin 32 around which the aerosol generating matrix sheet 31 is initially wound. The second compartment 4003 is a waste compartment for storing the aerosolized portion of the aerosol-generating matrix sheet 31. The internal volume of the second compartment 4003 is larger than the volume of the first compartment 4002. The aerosol-generating article 4000 also includes an inlet port 4004 disposed between the first compartment 4002 and the second compartment 4003. The inlet port 4004 allows access only through... Figure 16 The transparency is visible in the view and is therefore shown by dashed lines. The inlet port 4004 is in fluid communication with the interior of the housing 4001. The inlet port 4004 is adapted to receive the aerosolization unit 3006 of the aerosol generation device 3000, particularly the aerosolization element 261. Thus, the inlet port 4004 is sized such that the clamp 202 of the aerosol generation device 3000 can be received inside the housing 4001. Figure 16 In the example shown, the aerosol generating article 3000 does not have a mouthpiece. Instead, a mouthpiece 3003 is provided on the aerosol generating device 3000. Furthermore, in the case of… Figure 16 In the example shown, the aerosol-generating article 3000 does not have electronic components (such as batteries, sensors, or controllers).

[0378] The housing 4001 is formed as a first compartment 4002 connected to a second compartment 4003 via a tunnel 4005. The length 4007 of the tunnel 4005 extending between the first compartment 4002 and the second compartment 4003 can be between 2 mm and 50 mm. Figure 16 In a non-limiting example, the transverse cross-section of the tunnel is rectangular. An inlet port 4004 is provided on the wall of the tunnel 4005. Two air inlet slots 4006 are provided on the opposite walls of the tunnel 4005. A portion of the inlet port 4004 covers the two air inlet slots 4006. The aerosol generating article 4000 also includes a moving mechanism configured to move the aerosol generating matrix sheet 31 from the first compartment 4002 to the second compartment 4003. The moving mechanism is arranged inside the tunnel 4005. Figure 16In the non-limiting example shown, the moving mechanism includes a first pair of rollers 4008, 4009 arranged in a tunnel 4005 between the inlet port 4004 and the first compartment 4002. The moving mechanism also includes a second pair of rollers 4010, 4011 arranged in the tunnel 4005 between the second compartment 4003 and the inlet port 4004. Rollers 4008, 4009; 4010, 4011 may be friction rollers configured to engage and move the aerosol generating matrix sheet 31 by friction. The moving mechanism is configured to move the aerosol generating matrix sheet 31 from the first compartment 4002 to the second compartment 4003 in a conveying direction 312. The aerosol generating matrix sheet 31 is configured to pass between the rollers 4008, 4009 of the first pair of rollers. The aerosol generating matrix sheet 31 is also configured to pass between the rollers 4010, 4011 of the second pair of rollers. At least one of the rollers 4008, 4009; 4010, 4011 in each pair is configured to engage a corresponding driver 3010, 3011 of the aerosol generating apparatus 3000 when the aerosol generating article 4000 is inserted into the receiving portion 3004 of the aerosol generating apparatus 3000. The engagement of the rollers of the aerosol generating article 4000 with the corresponding drivers 3010, 3011 of the aerosol generating apparatus 3000 enables the torque of the corresponding drivers 3010, 3011 to be transmitted to at least one of the rollers 4008, 4009; 4010, 4011. Figure 16 In the example shown, roller 4009 is configured to engage driver 3010 (in Figure 14 (as shown in the diagram), and roller 4011 is configured to engage driver 3011 (in Figure 14 (As shown in the image).

[0379] Advantageously, tunnel 4005 may also be provided with an opening 4012 for receiving sensors. The opening 402 is located between the first pair of rollers 4008, 4009 and the first compartment 4002. Specifically, the opening 4012 allows for the positioning of an ultrasonic transducer (not shown) for indexing the conveyance of the aerosol generation matrix sheet 31. Alternatively or in combination, the aerosol generation apparatus 3000 may be provided with an encoder (not shown) for reading the angular position of the drives 3010, 3011. The encoder may be configured to read the angular position of the rotating shaft associated with the actuator 3008.

[0380] Advantageously, the housing 4001 of the aerosol generating article 4000 may be provided with at least one locking element (not shown) configured to be reversibly locked in the aerosol generating apparatus 3000.

[0381] Figure 17 Two opposing side views of a system including an aerosol generating apparatus 3000 and an aerosol generating article 4000 are shown. Figure 17The left side shows the battery 3020 of the aerosol generating apparatus 3000. The battery 3020 is rechargeable via charging port 3002. The aerosol generating apparatus 3000 includes a gear mechanism 3023 powered by a motor (not visible) to actuate drives 3010 and 3011 respectively. Drive 3010 then engages with roller 4008 of the aerosol generating article 4000 and transmits torque to said roller. Rotation of the lower roller 4008 generates rotation of the upper roller 4009, particularly through friction. Similarly, drive 3011 engages with roller 4010 of the aerosol generating article 4000 and transmits torque to said roller. Rotation of the lower roller 4010 generates rotation of the upper roller 4011, particularly through friction. The rotation of the first pair of rollers 4008 and the second pair of rollers 4010, 4011 allows the aerosol generating matrix 31 to be moved along the conveying direction 312 (i.e., from the first compartment 4001 toward the second compartment 4002) through the clamping elements 3021, 3022. Therefore, the unused portion 31 of the aerosol generating matrix 31 can be unwound and moved between the clamping elements 3021, 3022 for aerosolization. The used portion 33 of the aerosol generating matrix 31 can be moved to the second compartment 4002.

[0382] The gear mechanism 3023 may be similar to or even the same as the gear mechanism described with respect to the aerosol generating device 1000, and reference is made to the gear mechanism described thereto.

[0383] If only from Figure 17 As seen in the left view, the aerosol generating device 3000 includes an air passage 3024 in fluid communication with a mouthpiece 3003. In the illustrated example, the air passage 3024 is formed by a curved conduit. An airflow sensor 3025 is arranged along the air passage 3024. The airflow sensor 3025 is configured to detect the occurrence of suction and activate a motor (not visible) to actuate a gear mechanism 3023.

[0384] Similar to the aerosol generating device 1000, the motor of the gear mechanism 3023 configured to actuate the aerosol generating device 3000 can be configured to move the clamping elements 3021, 3022 of the clamp 202 in a manner in which the actuation of the clamp 202, the driver 3010 and the driver 3011 are mechanically decoupled from each other.

[0385] Figure 18 It shows Figure 17An enlarged view of the system is provided, in which the exemplary internal architecture of the aerosol generating device 3000 is partially visible. The gear mechanism 3023 includes a rotating shaft 3026. The rotating shaft 3026 can be actuated by a motor (not visible). The rotating shaft 3026 is configured to transmit torque to a first drive wheel 3027 of the gear mechanism 3023.

[0386] As in Figure 18 As can be seen in the cross-sectional view, the portion 31 of the aerosol generating matrix is ​​sandwiched between the aerosolizing element 261 of the clamping element 3021 and the aerosolizing element 261 of the clamping element 3022. The end 3026 of the air passage 3024 has a lateral outer wall 278 facing the receiving portion 268, which is provided with an air outlet 282. The aerosol generated in the aerosolization chamber 218 formed by the cavities 265 of the clamping elements 3021 and 3022 can flow through the air outlet 282, reach the air passage 3024, and then reach the mouthpiece 3003 for inhalation. Air can pass through the air inlet slot 4006 of the aerosol generating article 4000 (in... Figure 16 (as can be seen in the image) enters and enters through the air inlet 281 of the receiving section 268 (in the image). Figure 15 (See in the middle) Enters the aerosolization chamber 218.

[0387] As also Figure 18 As can be seen in the cross-sectional view, an airflow sensor 3025 is provided in the air passage 3024. Furthermore, in a non-limiting example shown, the aerosol generation apparatus 4000 also includes an ultrasonic transducer 27. The ultrasonic transducer 27 is configured to sense the position of the aerosol generation matrix sheet 31.

[0388] Figure 19 It shows that compared to in Figure 14 A better view of an elastic mechanism 3007 of the aerosol generating apparatus 3000. The elastic mechanism 3007 includes two arms 3028. The two arms 3028 are connected together at a common end 3029 of the arms 3038. Each arm 3038 has a through-hole 3031, specifically a circular through-hole 3031, at its relatively free end 3030. The size and dimensions of each through-hole 3031 correspond to the first contact pad 283 of the hollow receiving portion 268 (see...). Figure 15The sizes and dimensions of the arms 3028 are complementary. For each arm 3028, a form-fit connection is formed by engaging the first contact pad 283 in the through-hole 3031. A form-fit connection is also formed at the common end 3029 of the arms 3028 by engaging the contact pad 3032 of the aerosol generating device 3000 in the through-hole 3033. The contact pad 3032 and the through-hole 3033 each have a circular cross-section. The surface of each arm 3028 of the elastic mechanism 3007 is configured relative to the second contact pad 284 of the hollow receiving portion 268 (see...). Figure 15 The corresponding arm 3028 is movable relative to the second contact pad 284 of the hollow receiving portion 268. The displacement configuration of the corresponding arm 3028 relative to the second contact pad 284 of the hollow receiving portion 268 causes the clamping elements 3021, 3022 to move relative to each other between the open and closed configurations of the clamp 202. Specifically, the actuator 3008 of the aerosol generating device 3000 (in...) Figure 14 (As can be seen in the image) It is configured to push the clamping element 3021 toward the clamping element 3022 by means of the elastic connection between the clamping element 3021 and the clamping element 3022 provided by the elastic mechanism 3007.

[0389] In another instance (not shown), clamping elements 3021 and 3022 can be moved relative to each other by means of different mechanisms.

[0390] Figure 20 exist Figure 20 The left side schematically shows the sensor used for the indexing unit relative to... Figure 20 The arrangement of the aerosol generation matrix sheet shown on the right side, wherein the sensor for the indexing unit can be integrated into the aerosol generation device, particularly into any of aerosol generation devices 1000, 1010, 1020 and 3000.

[0391] Sensor 5000 is configured to determine the position of aerosol-generating matrix sheet 31, particularly the position relative to the aerosolization element of the aerosol-generating device (not shown). Sensor 5000 may be an ultrasonic transducer for indexing the position of aerosol-generating matrix sheet 31. Ultrasonic transducer 5000 is configured to emit ultrasound and measure the time of ultrasound return.

[0392] In the first example, an ultrasonic transducer 5000 is arranged in an aerosol generating apparatus and includes transmitter / receiver units 5001, 5002 for transmitting ultrasound to an aerosol generating matrix sheet 31. In an exemplary system including an aerosol generating apparatus 3000, the ultrasonic transducer 5001 may be configured to transmit and receive ultrasound via an opening 4012 in the aerosol generating article 4000. The opening 4012 is located in... Figure 16 The instructions are in accordance with the central government.

[0393] Alternatively, in the second example, the ultrasonic transducer 5003 includes a transmitter unit 5004 and a receiver unit 5005 positioned on the same side relative to the aerosol generating matrix sheet 31.

[0394] Alternatively, the ultrasonic transducer 5006 may include a transmitter unit 5007 and a receiver unit 5008 disposed on opposite sides of the aerosol generating matrix sheet 31.

[0395] Correspondingly, the aerosol generating matrix 31 can be advantageously provided with a pattern suitable for ultrasonic testing. Figure 20 On the right is shown a portion 311 of an aerosol-generating matrix sheet 31 according to an example. The aerosol-generating matrix sheet 31 includes a plurality of segments 313. The plurality of segments 313 are continuously interconnected to form a segmental sheet 31. The sheet 31 of segments 313 is provided with an aperture 314 at each joint 315 between consecutive segments 313. Each joint 315 interconnects two consecutive segments 313. Figure 20 As shown, the thickness of the aerosol generating matrix sheet 31 of each segment 313 is greater than the thickness of the aerosol generating matrix sheet 31 located at each joint 315 between consecutive segments 313.

[0396] The indexing unit's sensor is configured to detect the orifice 314 of the aerosol generation matrix sheet 31. This allows the indexing unit to determine the position of the aerosol generation matrix sheet 31, particularly its position relative to the aerosolization element of the aerosol generation device. The length 316 of the segment 313 along the direction of movement 312 of the aerosol generation matrix sheet 31 corresponds to the incremental step size generated by the indexing unit.
