Description

Technical Field

[0001] This disclosure relates to an aerosol generating apparatus. Background Technology

[0002] An aerosol generating apparatus for generating inhalable vapors is known. Such an apparatus can heat an aerosol forming matrix to a temperature that causes one or more components of the aerosol forming matrix to volatilize without burning the aerosol forming matrix. The aerosol forming matrix can be provided as part of an aerosol generating article. The aerosol generating article can be strip-shaped for insertion into a cavity of the aerosol generating apparatus. Once accommodated in the cavity, the aerosol generating apparatus can heat the aerosol generating article.

[0003] In some devices, the aerosol generating apparatus includes a blade-shaped heating element positioned within a cavity of the aerosol generating apparatus. The heating element can penetrate the aerosol-forming matrix of the aerosol generating article inserted into the cavity. Alternatively, once the aerosol generating article is contained within the cavity of the aerosol generating apparatus, heating equipment can be arranged around the cavity to heat the aerosol-forming matrix.

[0004] In either case, it is advantageous to hold the aerosol-generating article within the aerosol-generating apparatus to prevent it from falling out of the cavity during use of the apparatus and to provide effective heating of the aerosol-forming matrix by the apparatus. Heating blades can hold the aerosol-generating article within the cavity before heating it. Alternatively or additionally, before heating the aerosol-generating article, particularly for heating devices arranged around the cavity, retention of the aerosol-generating article within the cavity can be achieved by interference, since the diameter of the cavity corresponds to the diameter of the aerosol-generating article.

[0005] However, during operation, the dimensions of the aerosol generating article and the cavity can change due to heating of the aerosol generating article. For example, the diameter of the heated aerosol generating article, particularly the aerosol forming matrix, can shrink. When the aerosol generating apparatus is operating, the diameter of the cavity can increase due to thermal expansion. Furthermore, the aerosol forming matrix contained in the aerosol generating article can be depleted over time. This can further affect the shape of the aerosol generating article. In particular, the aerosol forming matrix can shrink as it is consumed. Dimensional changes in the aerosol generating article and the cavity during heating can lead to undesirable loosening of the aerosol generating article contained in the cavity.

[0006] Aerosol generating devices with cavities sized to correspond to specific aerosol-generating articles also have the disadvantage of making it difficult for users to insert the aerosol-generating articles into the cavities. Furthermore, such aerosol generating devices can only be used with aerosol-generating articles having a specific diameter.

[0007] It is desirable to provide an aerosol generating apparatus in which the insertion of aerosol generating articles into a cavity of the aerosol generating apparatus is improved, allowing aerosol generating articles of various diameters to be inserted into the cavity. It is also desirable to provide an aerosol generating apparatus in which the retention of aerosol generating articles contained in the cavity is improved, allowing aerosol generating articles of various diameters to be held in the cavity. Furthermore, it is desirable to provide an aerosol generating apparatus in which loosening of the aerosol generating articles contained in the cavity is prevented, particularly after heating. Summary of the Invention

[0008] This disclosure provides an aerosol generating apparatus. The aerosol generating apparatus may include an apparatus housing. The apparatus housing may define a cavity. The aerosol generating apparatus may further include an adjustable holding element. The adjustable holding element may be positioned in or adjacent to the cavity. The adjustable holding element may define a channel. The aerosol generating apparatus may further include an actuating device. The actuating device may be configured to actuate the adjustable holding element between a receiving position and a holding position. When the adjustable holding element is in the receiving position, the cross-sectional dimension of the channel may be larger than the cross-sectional dimension when the adjustable holding element is in the holding position.

[0009] In one example, the aerosol generating apparatus includes an apparatus housing defining a cavity; an adjustable holding element positioned within or adjacent to the cavity and defining a channel; and an actuating device configured to actuate the adjustable holding element between a receiving position and a holding position; wherein the cross-sectional dimension of the channel is larger when the adjustable holding element is in the receiving position than when the adjustable holding element is in the holding position.

[0010] By providing an adjustable retaining element positioned in or adjacent to the cavity, any object contained in or removed from the cavity must pass through a channel defined by the adjustable retaining element. An object contained in the cavity can also be contained within the channel.

[0011] When the adjustable retaining element is in the receiving position, an object having a cross-sectional dimension smaller than the equivalent cross-sectional dimension of the channel can advantageously pass freely through the channel. This ensures that the object is not obstructed by the adjustable retaining element when inserted into or removed from the cavity. If the equivalent cross-sectional dimension of the object is also greater than or equal to the cross-sectional dimension of the channel when the adjustable retaining element is in the retaining position, the object is prevented from passing through the channel. This is particularly advantageous when the distal end of the object is received in the cavity and the remainder of the object protrudes from the cavity to be received in the channel. In such a device, the adjustable retaining element advantageously contacts and holds the object in the channel. When the cross-sectional dimension of the channel is smaller than the cross-sectional dimension of the object and the object is received in the channel, the object or the adjustable retaining element may deform slightly when the adjustable retaining element is in the retaining position.

[0012] By providing an adjustable retaining element with a defined channel having a cross-sectional dimension that changes when the adjustable retaining element is actuated between a receiving position and a holding position, objects of a range of sizes can be advantageously received and held by the adjustable retaining element.

[0013] As used herein, the term "cross-sectional dimension" is generally used to refer to any dimension of a two-dimensional cross-section of a channel. The cross-section of a channel can be a cross-section of the channel. As used herein, the term "cross-section" refers to a cross-section defined by the width of the channel such that the cross-section is perpendicular to the length of the channel. In particular, the cross-section can be perpendicular to the direction in which an object is inserted into the cavity through the channel. Cross-sectional dimensions include the width or area of ​​the channel's cross-section. Different shapes of cross-sections can have different cross-sectional dimensions. For example, if a channel has a circular cross-section, then the diameter of the cross-section is the cross-sectional dimension.

[0014] When the adjustable retaining element is actuated from the receiving position to the retaining position, the adjustable retaining element can deform. The deformed adjustable retaining element can restrict the channel. The cross-sectional dimensions can be related to the cross-section of the contraction in the channel.

[0015] The cross-sectional dimension of the channel can be the width of the channel. The width of the channel can be the width of the channel's cross-section. When the adjustable retaining element is in the receiving position, the channel width can be between 5 mm and 13 mm. Preferably, when the adjustable retaining element is in the receiving position, the channel width can be between 6 mm and 9 mm. When the adjustable retaining element is in the receiving position, the channel width can be greater than the width of the object to be received or passed through the channel.

[0016] When the adjustable retaining element is in the retaining position, the width of the channel can be between 3 mm and 8 mm. Preferably, when the adjustable retaining element is in the retaining position, the width of the channel can be between 2.5 mm and 6.5 mm. When the adjustable retaining element is in the retaining position, the width of the channel can be less than or equal to the width of the object to be accommodated or pass through the channel.

[0017] The adjustable retaining element can circumferentially surround the channel. The cross-sectional dimension of the channel can be its cross-sectional area. The cross-sectional area of ​​the channel can be between 20 square millimeters and 130 square millimeters when the adjustable retaining element is in the receiving position. For example, when the diameter of the channel is 5 millimeters when the adjustable retaining element is in the receiving position, the cross-sectional area of ​​the channel is 19.6 square millimeters. Preferably, the cross-sectional area of ​​the channel can be between 30 square millimeters and 60 square millimeters when the adjustable retaining element is in the receiving position. When the adjustable retaining element is in the receiving position, the cross-sectional area of ​​the channel can be larger than the cross-sectional area of ​​the object to be received or passed through the channel.

[0018] When the adjustable retaining element is in the retaining position, the cross-sectional area of ​​the channel is between 7 and 50 square millimeters. For example, when the diameter of the channel is 3 millimeters when the adjustable retaining element is in the retaining position, the cross-sectional area of ​​the channel is 7.1 square millimeters. Preferably, when the adjustable retaining element is in the retaining channel, the cross-sectional area of ​​the channel can be between 5 and 30 square millimeters. When the adjustable retaining element is in the retaining position, the cross-sectional area of ​​the channel can be less than or equal to the cross-sectional area of ​​the object to be accommodated or passed through the channel.

[0019] An adjustable retaining element defines a channel inlet and a channel outlet. When the adjustable retaining element is in the retaining position, the cross-sectional dimensions of the channel can vary between the channel inlet and the channel outlet. When the adjustable retaining element is in the receiving position, the cross-sectional dimensions of the channel can be constant between the channel inlet and the channel outlet. Alternatively, the cross-sectional dimensions of the channel can vary to a lesser extent than when the adjustable retaining element is in the retaining position. In other words, the channel profile between the channel inlet and the channel outlet can be different when the adjustable retaining element is in the receiving position compared to when the adjustable retaining element is in the retaining position. This can be a result of deformation of the adjustable retaining element when it is actuated from the retaining position to the receiving position.

[0020] The cross-sectional dimension can be the minimum cross-sectional area of ​​the channel. When the adjustable retaining element is in the retaining position, the cross-sectional dimension can be the minimum cross-sectional area of ​​the channel.

[0021] In the holding position, the adjustable holding element may include a surface defined between a channel inlet and a channel outlet, said surface having a curved cross-section. In other words, in the holding position, the cross-sectional dimensions of the channel may vary between the channel inlet and the channel outlet. A portion of the curved shape may include a convex curve that defines a contraction in the channel at the inflection point of the convex curve. The contraction may form a contact point between the adjustable holding element and an object housed within the channel of the adjustable holding element. The contraction may retain the object within the channel of the adjustable holding element. The cross-sectional dimensions may be the cross-sectional dimensions of the contraction.

[0022] As used herein, the term "longitudinal section" refers to the cross-section defined by an adjustable retaining element parallel to the channel length. As mentioned above, the longitudinal section can be defined in a direction perpendicular to the cross-section. Therefore, the longitudinal section can be defined in a direction parallel to the insertion direction of an object entering the cavity through the channel.

[0023] The curved shape may include a second convex curve that defines a second contraction in the channel at the inflection point of the second convex curve. The second contraction may form a second contact point between the adjustable retaining element and an object housed in the channel of the adjustable retaining element. The cross-sectional dimensions of the second contraction may be the same as those of the first contraction.

[0024] The surface can extend around a portion of the channel to form a ring, a partial ring, or a truncated ring.

[0025] When the adjustable retaining element is actuated from the receiving position to the retaining position, the distance between the channel inlet and channel outlet can be reduced by between 2.5 mm and 5 mm. By reducing the distance between the channel inlet and channel outlet, the adjustable retaining element can deform. Deformation can reduce the cross-sectional size. A reduction between 2.5 mm and 5 mm allows the adjustable retaining element to deform such that the cross-sectional size is reduced to be less than or equal to the cross-sectional size of the object to be inserted into the cavity.

[0026] The adjustable retaining element can be annular. The adjustable retaining element can be configured to contract radially when actuated from the receiving position to the retaining position. The adjustable retaining element can contract by an equal amount around the radius of the channel.

[0027] The cavity can be a cavity for containing an aerosol-generating article. The cavity can be a cavity for containing at least a distal portion of the aerosol-generating article. A portion of the aerosol-generating article contained in the cavity may be located within a channel.

[0028] The aerosol-generating article can be rod-shaped. In other words, the aerosol-generating article can have a circular cross-section. In this case, preferably, the adjustable holding element is annular. The adjustable holding element in the holding position can contact the aerosol-generating article contained in the cavity around its entire circumference.

[0029] The annular adjustable retaining element can contract radially. The annular adjustable retaining element can advantageously contract uniformly around the radius of the channel. When the annular adjustable retaining element is in the holding position, it can advantageously contract radially to contact the aerosol-generating article around its entire circumference. The annular adjustable retaining element can advantageously apply equal pressure around the circumference of the aerosol-generating article.

[0030] The diameter of the aerosol-generating article can be between 3 mm and 8 mm. Preferably, the diameter of the aerosol-generating article can be between 4 mm and 7 mm. Preferably, the diameter of the channel is larger than the diameter of the aerosol-generating article when the adjustable retaining element is in the receiving position.

[0031] When the adjustable retaining element is in the receiving position, the diameter of the aerosol-generating article can be between 0.5 mm and 3.5 mm smaller than the width of the channel. This advantageously ensures that the aerosol-generating article is not obstructed by the adjustable retaining element. The aerosol-generating article is also unobstructed when inserted into or removed from the cavity through the channel.

[0032] Preferably, when the adjustable holding element is in the holding position, the diameter of the channel is less than or equal to the diameter of the aerosol-generating article. This advantageously ensures that contact is maintained between the adjustable holding element and the aerosol-generating article, although the diameter of the aerosol-generating article is variable, for example, during heating of the aerosol-generating article.

[0033] The aerosol-generating article can have a cross-sectional area between 5 square millimeters and 50 square millimeters. For example, if the cross-sectional diameter of the aerosol-generating article is 3 millimeters, then the cross-sectional area of ​​the aerosol-generating article can be 7.1 square millimeters. Preferably, the aerosol-generating article can have a cross-sectional area between 10 square millimeters and 40 square millimeters. Preferably, when the adjustable holding element is in the receiving position, the cross-sectional area of ​​the channel is larger than the diameter of the aerosol-generating article.

[0034] Preferably, when the adjustable retaining element is in the retaining position, the cross-sectional area of ​​the channel is less than or equal to the diameter of the aerosol-generating article. When the adjustable retaining element is in the receiving position, the cross-sectional area of ​​the aerosol-generating article can be between 3 and 60 square millimeters smaller than the cross-sectional area of ​​the channel.

[0035] When the adjustable retaining element is in the receiving position, the aerosol-generating article can be freely received or removed from the cavity. Therefore, inserting and removing the aerosol-generating article from the cavity can be advantageously simple.

[0036] The adjustable holding element can be configured to contact the aerosol-generating article contained in the cavity when the adjustable holding element is in the holding position. The adjustable holding element can also be configured to grip the aerosol-generating article contained in the cavity when the adjustable holding element is in the holding position. The interference relationship between the aerosol-generating article and the adjustable holding element can advantageously hold the aerosol-generating article within the cavity.

[0037] The adjustable holding element can contact two separate portions of the aerosol-generating article. These two separate portions can be spaced apart along the length of the aerosol-generating article. Providing two contact points between the aerosol-generating article and the adjustable holding element increases the contact area.

[0038] In the held position, the adjustable retaining element is configured to seal, for example, the cavity hermetically when the aerosol-generating article is received in the cavity, while allowing airflow through the aerosol-generating article. The outer circumference of the resilient sealing element can engage with the housing of the aerosol-generating device. The attachment between the housing of the aerosol-generating device and the resilient sealing element can be a hermetically sealed attachment. The adjustable retaining element can allow airflow through a channel defined by the adjustable retaining element. However, after the aerosol-generating article is inserted into the cavity, the channel can be filled by the aerosol-generating article, so that air can only exit the cavity through the aerosol-generating article. Providing an adjustable retaining element configured to contact both portions of the aerosol-generating article when the adjustable retaining element is in the held position can result in an increased or more robust sealing effect.

[0039] The aerosol-generating article can be contained in the cavity along the longitudinal direction. When the adjustable retaining element is actuated from the containing position to the retaining position, the adjustable retaining element can be compressed in the longitudinal direction. The adjustable retaining element may include a contact portion configured to move in a direction perpendicular to the longitudinal direction when the adjustable containing element is actuated from the containing position to the retaining position.

[0040] The contact portion of the adjustable retaining element can move toward the aerosol-generating article housed in the cavity.

[0041] The contact portion of the adjustable retaining element can move between 1 mm and 4 mm. When the adjustable retaining element is in the retaining position, the contact portion of the adjustable retaining element can restrict the passage.

[0042] The adjustable retaining element can be an elastic element. Such an elastic element can be actuated between a receiving position and a retaining position having an adjustable cross-sectional size without requiring complex mechanical assembly. For example, when actuated from the receiving position to the retaining position, the elastic element can deform. Deformation may change the relevant cross-sectional size. Preferably, the elastic element can deform in the longitudinal direction, resulting in a contraction of the channel defined by the elastic element.

[0043] Furthermore, when the adjustable elastic element is in the holding position, the elastic element can apply pressure to the aerosol-generating article within the channel. When the cross-sectional dimension of the channel is smaller than the cross-sectional dimension of the aerosol-generating article, the elastic element can apply pressure to the aerosol-generating article within the channel. This pressure holds the aerosol-generating article in the appropriate position within the channel. Pressure can be applied in a direction perpendicular to the longitudinal direction.

[0044] The adjustable retaining element can be flexible. The adjustable retaining element can be elastic. The adjustable retaining element can have a central hole through which a channel is defined. The adjustable retaining element can be made of a material with suitable elastic properties, thereby causing the adjustable retaining element to deform between a receiving position and a retaining position. The adjustable retaining element can be made of elastic, heat-resistant polymers or compound materials such as graphene, silicone, plastics, or other suitable materials or compounds thereof. For example, it may be advantageous for at least one deformable portion of the adjustable retaining element to be made of an elastomeric polymer, such as butyl rubber like polyisobutylene, polysiloxanes like silicone, polyurethane, or other elastomers.

[0045] The actuating device may be movable relative to the device housing. The actuating device may move between a first position relative to the device housing (where the adjustable retaining element is in the received position) and a second position relative to the device housing (where the adjustable retaining element is in the retaining position).

[0046] A first side of the adjustable retaining element may engage with an actuating device. The first side of the adjustable retaining element may define a channel inlet. A second side of the adjustable retaining element may engage with a device housing. The second side of the adjustable retaining element may define a channel outlet.

[0047] The actuator can be engaged with the device housing via threads and threaded connections. The actuator can move relative to the device housing via threads and threaded connections.

[0048] Alternatively, the actuating device can be engaged to the device housing via a connecting member. The connecting member can consist of one or more pins or grooves formed in the housing of the actuating device. The pins or grooves of the connecting member can engage slots or recesses formed in the device housing. The actuating device movable relative to the device housing can be guided by the pins or grooves of the connecting member that move in the slots or recesses. The slots or recesses can be configured such that the actuating device can move from a first position where the adjustable retainer is in a receiving position and a second position where the adjustable retainer is in a holding position. The slots or recesses can be configured such that when a user pushes the actuating device in the longitudinal direction, the actuating device is moved from the first position to the second position.

[0049] The actuating device may include a spring. The spring may contact the device housing. Moving the actuating device from a first position to a second position will deform the spring. The deformed spring can cause the actuating device to return to the first position.

[0050] The slot or recess may include a locking portion. When the actuator is in the second position, the engaging member can be pushed into the locking portion. A user pushing the actuator longitudinally can push the engaging member back out of the locking portion of the slot or recess. The user can push the actuator in the same direction to move it from the first position to the second position and remove the engaging member from the locking portion of the slot or recess. The actuator can then be pushed back into the first position by a spring. This device is advantageously simple for user operation. The user simply presses the actuator to move it from the first position to the second position and back to the first position.

[0051] The actuator can rotate between a first position and a second position. The first and second positions can be separated by 90 degrees and 270 degrees. For example, the first and second positions can be separated by 180 degrees.

[0052] The actuating device may include a housing. An adjustable retaining element may be engaged with the housing of the actuating device. A portion of a cavity may be defined by the actuating device.

[0053] As used herein, the term "aerosol generating device" describes an apparatus that interacts with an aerosol generating matrix of an aerosol generating article to generate an aerosol. Preferably, the aerosol generating device is an apparatus that interacts with an aerosol generating matrix of an aerosol generating article to generate an aerosol that can be inhaled directly into the lungs of a user through the user's mouth. The apparatus may be configured to heat the aerosol forming matrix. The device may include a heating device. The heating device may include a heating element located within a cavity and configured to penetrate the aerosol forming matrix of the aerosol generating article. Alternatively, the heating device may be arranged around the cavity.

[0054] The heating device can be a resistance heating device.

[0055] The heating device can be an induction heating device. An induction heating device can be configured to generate heat by induction. An induction heating device can include an induction coil and a sensor device. A single induction coil can be provided. A single sensor device can be provided. Preferably, more than one induction coil is provided. A first induction coil and a second induction coil can be provided. Preferably, more than one sensor device is provided. Preferably, a first sensor device and a second sensor device are provided. The induction coil can surround the sensor device. The first induction coil can surround the first sensor device. The second induction coil can surround the second sensor device. Alternatively, at least two induction coils can be provided around a single sensor device. If more than one sensor device is provided, preferably, an electrical insulating element is provided between the sensor devices.

[0056] The induction coil can be arranged within a coil chamber. The coil chamber can be sealed to the cavity by an insulating element at its downstream end. The coil chamber can be arranged to surround the cavity. The coil chamber can partially or completely surround the cavity. The coil chamber can extend along the entire length of the cavity. The coil chamber can house one or more induction coils.

[0057] The aerosol generating device may include a downstream air inlet connected to the coil compartment. Alternatively, the aerosol generating device may include an air inlet at an upstream end adjacent to the cavity. The air inlet may be in fluid connection to an air orifice in the bottom of the cavity.

[0058] The aerosol generating apparatus may include a power supply. The power supply may be a direct current (DC) power supply. The power supply may be electrically connected to a first induction coil. In one embodiment, the power supply is a DC power supply having a DC power supply voltage in the range of about 2.5 volts to about 4.5 volts and a DC power supply current in the range of about 1 ampere to about 10 amperes (corresponding to a DC power supply in the range of about 2.5 watts to about 45 watts). The aerosol generating apparatus may advantageously include a DC-to-AC (DC / AC) inverter for converting the DC current supplied by the DC power supply into AC power. The DC / AC converter may include a Class D or Class E power amplifier. The power supply may be configured to provide AC power.

[0059] The power source can be a battery, such as a rechargeable lithium-ion battery. Alternatively, the power source can be another form of charge storage device, such as a capacitor. The power source may require recharging. The capacity of the power source can allow storing enough energy for the aerosol generating device to use once or multiple times. For example, the power source can have sufficient capacity to allow continuous aerosol generation for approximately six minutes, corresponding to the typical time required to smoke a regular cigarette, or for multiple six-minute periods. In another instance, the power source can have sufficient capacity to allow for a predetermined number of puffs or discrete activation.

[0060] The power supply can be configured to operate at high frequencies. As used herein, the term "high-frequency oscillating current" refers to an oscillating current with a frequency between 500 kHz and 30 kHz. The frequency of the high-frequency oscillating current can be from about 1 MHz to about 30 MHz, preferably from about 1 MHz to about 10 MHz, and more preferably from about 5 MHz to about 8 MHz.

[0061] The sensor device may include sensors. The sensor device may include multiple sensors. The sensor device may include blade-shaped sensors. Blade-shaped sensors may be arranged around a cavity. Blade-shaped sensors may be arranged inside the cavity. When an aerosol generation article is inserted into the cavity, the blade-shaped sensors may be arranged to accommodate the aerosol generation article. The blade-shaped sensors may have an open downstream end to facilitate insertion of the aerosol generation article into the blade-shaped sensors. Air may flow into the cavity through air orifices in the bottom of the cavity. Air may then enter the aerosol generation article at the upstream end face of the aerosol generation article. Alternatively or additionally, air may flow between the sidewalls of the cavity and the blade-shaped sensors. Air may then enter the aerosol generation article through gaps between the blade-shaped sensors. In this way, uniform permeation of the aerosol generation article with air can be achieved, thereby optimizing aerosol generation.

[0062] Aerosol generating devices may include flux concentrators. Flux concentrators may be made of materials with high magnetic permeability. Flux concentrators may be arranged around induction heating devices. Flux concentrators can concentrate magnetic field lines into the interior of the concentrator, thereby increasing the heating effect of the sensing device by means of induction coils.

[0063] The aerosol generating apparatus may include a controller. The controller may be electrically connected to induction coils. The controller may be electrically connected to a first induction coil and a second induction coil. The controller may be configured to control the current supplied to the induction coils, and thus control the strength of the magnetic field generated by the induction coils.

[0064] A power supply and controller can be connected to the induction coils (preferably the first and second induction coils) and configured to independently supply alternating current to each induction coil, such that each induction coil generates an alternating magnetic field during use. This means that the power supply and controller can supply alternating current to the first induction coil alone, to the second induction coil alone, or to both induction coils simultaneously. Different heating profiles can be achieved in this way. The heating profile can refer to the temperature of the respective induction coil. To heat to a high temperature, alternating current can be supplied to both induction coils simultaneously. To heat to a lower temperature or to heat only a portion of the aerosol-forming matrix of the aerosol-generating article, alternating current can be supplied to only the first induction coil. Subsequently, alternating current can be supplied to only the second induction coil.

[0065] The controller can be connected to the induction coil and a power source. The controller can be configured to control the supply of power from the power source to the induction coil. The controller may include a microprocessor, which can be a programmable microprocessor, a microcontroller, an application-specific integrated circuit (ASIC), or other circuitry capable of providing control. The controller may include other electronic components. The controller can be configured to regulate the current supply to the induction coil. After the aerosol generating device is activated, the current can be continuously supplied to one or both of the induction coils, or it can be supplied intermittently, such as on a successive pumping basis.

[0066] The power supply and controller can be configured to independently change the amplitude of the alternating current supplied to each of the first and second induction coils. With this arrangement, the strength of the magnetic field generated by the first and second induction coils can be independently varied by changing the amplitude of the current supplied to each coil. This facilitates a conveniently variable heating effect. For example, the amplitude of the current supplied to one or both coils during startup can be increased to reduce the startup time of the aerosol generating device.

[0067] The first induction coil of the aerosol generating device can form part of a first circuit. The first circuit can be a resonant circuit. The first circuit can have a first resonant frequency. The first circuit may include a first capacitor. The second induction coil can form part of a second circuit. The second circuit can be a resonant circuit. The second circuit can have a second resonant frequency. The first resonant frequency may be different from the second resonant frequency. The first resonant frequency may be the same as the second resonant frequency. The second circuit may include a second capacitor. The resonant frequency of the resonant circuit depends on the inductance of the corresponding induction coil and the capacitance of the corresponding capacitor.

[0068] The cavity of the aerosol generating apparatus may have an open end into which the aerosol-generated article is inserted. The cavity may also have a closed end opposite the open end. The closed end may be the bottom of the cavity. The closed end may be closed except for providing air vents disposed in the bottom. The bottom of the cavity may be flat. The bottom of the cavity may be circular. The bottom of the cavity may be located upstream of the cavity. The open end may be located downstream of the cavity.

[0069] The cavity can be configured as a heating chamber. The cavity can have a cylindrical shape. The cavity can have a hollow cylindrical shape. The cavity can have a circular cross-section. The cavity can have an elliptical or rectangular cross-section. The cavity can correspond to the diameter of the aerosol-generating article.

[0070] As used herein, the term "proximal" refers to the user end or mouth end of the aerosol generating device, and the term "distal" refers to the end opposite to the proximal end. When referring to a cavity, the term "proximal" refers to the region closest to the open end of the cavity, and the term "distal" refers to the region closest to the closed end.

[0071] As used herein, the term "length" refers to the principal dimension in the longitudinal direction of the aerosol generating apparatus, the longitudinal direction of the aerosol generating article, or the longitudinal direction of a component of the aerosol generating apparatus or the aerosol generating article.

[0072] As used herein, the term "width" refers to the principal dimension at a specific location along its length in the transverse direction of the aerosol generating apparatus, the aerosol generating article, or a component of the aerosol generating apparatus or aerosol generating article. The term "thickness" refers to the dimension in the transverse direction perpendicular to the width.

[0073] As used herein, the term "aerosol forming matrix" refers to a matrix capable of releasing volatile compounds that can form aerosols. Such volatile compounds can be released by heating the aerosol forming matrix. The aerosol forming matrix is ​​part of an aerosol-generating article.

[0074] As used herein, the term "aerosol generating article" refers to an article comprising an aerosol-forming matrix capable of releasing volatile compounds that can form aerosols. For example, an aerosol generating article may be an article that generates an aerosol that can be directly inhaled by a user by drawing or inhaling it through a mouthpiece at the proximal end or user end of the system. Aerosol generating articles may be disposable. Articles comprising an aerosol-forming matrix containing tobacco are referred to as tobacco sticks. Aerosol generating articles may be inserted into the cavity of an aerosol generating device.

[0075] As used herein, the term "aerosol generating apparatus" refers to an apparatus that interacts with an aerosol generating article to generate aerosols.

[0076] As used herein, the term "aerosol generation system" refers to a combination of an aerosol generation article as further described and illustrated herein and an aerosol generation device as further described and illustrated herein. In this system, the aerosol generation article and the aerosol generation device cooperate to generate an inhalable aerosol. The present invention may also relate to an aerosol generation system.

[0077] As used herein, "sensor device" means a conductive element that heats when subjected to a changing magnetic field. This may be due to eddy currents, hysteresis losses, or both eddy currents and hysteresis losses induced in the sensor device. During use, the sensor device is positioned in thermal contact or close thermal proximity with the aerosol-forming matrix of the aerosol-generating article contained in the cavity of the aerosol-generating apparatus. In this way, the aerosol-forming matrix is ​​heated by the sensor device, thereby forming an aerosol.

[0078] The sensor device can have a cylindrical shape, preferably consisting of a single leaf-shaped sensor. The sensor device can have a shape corresponding to the shape of the corresponding induction coil. The sensor device can have a diameter smaller than the diameter of the corresponding induction coil, allowing the sensor device to be arranged inside the induction coil.

[0079] The term "heating zone" refers to a portion of the cavity's length that is at least partially surrounded by an induction coil, such that a sensor device placed in or around the heating zone can be inductively heated by the induction coil. The heating zone may include a first heating zone and a second heating zone. The heating zone may be divided into a first heating zone and a second heating zone. The first heating zone may be surrounded by a first induction coil. The second heating zone may be surrounded by a second induction coil. More than two heating zones may be provided. Multiple heating zones may be provided. An induction coil may be provided for each heating zone. One or more induction coils may be arranged movable to surround the heating zone and configured for segmented heating of the heating zone.

[0080] As used herein, the term "coil" may be used interchangeably with the terms "inductor coil," "induction coil," "inductor," or "inductor coil." A coil may be a driving (primary) coil connected to a power source.

[0081] Preferably, the aerosol generating device is portable. The aerosol generating device can have a size comparable to a conventional cigar or cigarette.

Examples of suitable materials include metals, alloys, plastics, or composites containing one or more of those materials, or thermoplastic materials suitable for food or pharmaceutical applications, such as polypropylene, polyetheretherketone (PEEK), and polyethylene. Preferably, the material is lightweight and not easily broken.

[0083] The housing may include a mouthpiece. The mouthpiece may include at least one air inlet and at least one air outlet. The mouthpiece may include more than one air inlet. One or more air inlets can reduce the temperature of the aerosol before it is delivered to the user, and can reduce the concentration of the aerosol before it is delivered to the user. Preferably, the mouthpiece may be provided as part of an aerosol generating article.

[0084] As used herein, the term "mouthpiece" refers to an aerosol generating device or part of an aerosol generating article that is placed in the mouth of a user to allow direct inhalation of aerosols generated by the aerosol generating device from a cavity contained in a housing.

The airflow rate is a parameter characterizing the amount of air drawn in by the user each time through the airflow path of the aerosol generating device. The start of suction can be detected by the airflow sensor when the airflow exceeds a predetermined threshold. Start can also be detected when the user activates the button.

[0086] The sensor can also be configured as a pressure sensor to measure the pressure of the air inside the aerosol generating device, which is drawn through the airflow path of the device by the user during inhalation. The sensor can be configured to measure the pressure difference, or pressure drop, between the pressure of the ambient air outside the aerosol generating device and the pressure of the air drawn through the device by the user. The air pressure can be detected at the air inlet, the device's nozzle, a cavity such as a heating chamber, or any other passage or chamber within the aerosol generating device through which the air flows. When the user inhales onto the aerosol generating device, a negative pressure or vacuum is created inside the device, where the negative pressure can be detected by the pressure sensor.

[0087] The term "negative pressure" should be understood as a pressure that is relatively lower than the pressure of ambient air. In other words, when a user inhales through the device, the air drawn through the device has a lower pressure than the ambient air outside the device. If the pressure difference exceeds a predetermined threshold, the start of inhalation can be detected by a pressure sensor.

[0088] The aerosol generating device may include a user interface for activating the aerosol generating device, such as a button for initiating heating of the aerosol generating device or a display for indicating the status of the aerosol generating device or the aerosol forming matrix.

[0210] The aerosol generating apparatus 1 may include other components not shown in the figures, such as a controller for controlling the induction heating device. If the induction heating device includes more than one induction coil 16, the controller may be configured to control each coil individually. The aerosol generating apparatus 1 may include a power source such as a battery. The controller may be configured to control the electrical energy supply from the power source to the induction coil 16 or the individual induction coils 16.

[0211] A thermally insulating element 22 is disposed between the sensor device 14 and the induction coil 16. The thermally insulating element 22 forms the sidewall of the cavity 10. The thermally insulating element 22 has an elongated extension. The thermally insulating element 22 has a hollow cylindrical shape. The thermally insulating element 22 is attached to the housing 24 of the aerosol generating device 1. Preferably, as shown... Figure 1 As depicted, the thermal insulation element 22 is attached to the downstream end of the housing 24. Preferably, the thermal insulation element 22 is attached to the bottom 28 of the cavity 10 at the downstream end of the cavity 10. One or more air vents 30 are arranged in the bottom 28 of the cavity 10.

[0212] The air orifice 30 has an elongated extension parallel to the longitudinal axis of the aerosol generating device 1. The air orifice 30 allows air to enter the cavity 10 at the upstream end 32. The thermal insulation element 22 prevents air from entering the cavity 10 laterally from 25.

[0213] An induction coil 16 is arranged in a coil compartment 34. The coil compartment 34 is arranged around a thermally insulating element 22. A cavity 10 is centrally located in the layered structure. The thermally insulating element 22 is provided around the cavity 10. The coil compartment 34 is arranged around the thermally insulating element 22. The housing 24 of the aerosol generating device 1 is provided around the coil compartment 34.

[0214] An air inlet 36 is provided to allow ambient air to enter the coil compartment 34. The air inlet 36 is located at the downstream end of the housing 24. The air inlet 36 is located near the coil compartment 34. The air inlet 36 is positioned between the outer circumference of the housing 24 and the portion of the housing 24 connected to the downstream end of the thermal insulation element 22. Alternatively, as... Figure 1As shown, the air inlet 36 is placed in the side wall of the housing 24 of the aerosol generating device 1. In other words, the air inlet 36 is placed in the outer circumference of the housing 24 of the aerosol generating device 1. The air inlet 36 is arranged near the upstream end of the cavity 10.

[0215] Although the aerosol generating device 1 has been described as including an induction heating system with a sensor device, this sensor device can be replaced by a resistance heating system. For example, the resistance heating system may include resistance heating blades instead of sensor blades. The controller can be configured to control the electrical energy supply from the power source to the resistance heater blades.

[0216] Although the aerosol generating apparatus 1 has been described as including a sensor device configured to heat the aerosol generating article from the outside, this sensor device can be replaced by a heating element that penetrates the aerosol generating article housed in the cavity. The heating element can be configured to penetrate the aerosol forming matrix of the aerosol generating article housed in the cavity. The heating element can be a sensor element that operates similarly to the sensor device described above, or it can be a resistance heating element.

[0217] Although the aerosol generating apparatus 1 has been described as including a sensor element, the sensor element may alternatively be part of the aerosol generating article.

[0218] The aerosol generating apparatus 1 also includes an actuator 50 and an adjustable holding element 60. The adjustable holding element 60 defines a channel 62. A first side of the adjustable holding element 60 engages the actuator 50 and defines a channel inlet 64. A second side of the adjustable holding element engages with the housing of the apparatus 24 and defines a channel outlet 66.

[0219] Figure 1 An aerosol generating article 12 is shown inserted into cavity 10 such that its distal end is received within the cavity. This distal end includes the aerosol-forming matrix portion of the aerosol generating article (not shown). A filter tip portion 20 of the aerosol generating article protrudes from the cavity for a user to inhale onto the aerosol generating article 12. The protruding filter tip portion 20 of the aerosol generating article is received within channel 62. Thus, when the cavity is confined within the device housing, the actuating device 50 and the channel defined by the adjustable holding element effectively extend the cavity beyond the device housing 24.

[0220] The adjustable retaining element 60 can be actuated between a receiving position and a retaining position. Figure 1 The adjustable retaining element 60 is shown in the retaining position. The receiving position and retaining position of the adjustable retaining element 60 are respectively at... Figure 2 and Figure 3 It is shown more clearly in the middle.

[0221] exist Figure 2 In this configuration, the adjustable retaining element 60 is shown in the receiving position, such that the adjustable retaining element 60 does not contact the aerosol generating article 12. The width of the channel 62 defined by the adjustable retaining element 60 in the receiving position is greater than the diameter of the aerosol generating article 12. The cross-sectional area of ​​the channel 62 defined by the channel is greater than the cross-sectional area of ​​the aerosol generating article. This configuration allows for easy insertion of the aerosol generating article 12 into the cavity.

[0222] exist Figure 3 In this configuration, the adjustable retaining element 60 is shown in a retaining position, such that the adjustable retaining element is in contact with the aerosol generating article 12. When the aerosol generating article 12 is not present in the channel 62, the channel width defined by the adjustable retaining element 60 in the retaining position is smaller than the diameter of the aerosol generating article 12. Similarly, the cross-sectional area of ​​the channel 62 is smaller than the cross-sectional area of ​​the aerosol generating article 12. This means that when the adjustable retaining element 60 is accommodated in the channel and actuated to the retaining position, the adjustable retaining element 60 engages with and is deformed by the outer surface of the aerosol generating article 12. The adjustable retaining element 60 is made of an elastic and resilient material. Therefore, the deformation of the adjustable retaining element 60 causes it to apply pressure to the aerosol generating article 12. This pressure retains the aerosol generating article 12 within the channel and thus within the cavity.

[0223] The channel width is 9 mm when the adjustable retaining element is in the receiving position. The channel width is 5 mm when the adjustable retaining element is in the holding position. Therefore, an aerosol generating article 12 with a diameter between 5 mm and 9 mm can be received and held by the adjustable retaining element 60.

[0224] When the aerosol-generating article contained in the cavity is heated, it can shrink. This can be a result of heating the aerosol-generating article during operation of the aerosol-generating device or as a result of depletion of the aerosol-forming matrix. This shrinkage can lead to radial shrinkage of the aerosol-generating article. Therefore, the aerosol-generating article 12 contained in the channel preferably has a diameter of at least 5.5 mm. In other words, when the adjustable holding element 60 is in the holding position, the aerosol-generating article 12 preferably has a diameter slightly larger than the width of the channel 62. This ensures that contact is maintained between the adjustable holding element 60 and the aerosol-generating article 12, even when the diameter of the aerosol-generating article 12 varies, for example, as a result of heating the aerosol-generating article 12.

[0225] The adjustable holding element 60 is actuated between a receiving position and a holding position by an actuating device 50. The actuating device 50 is movable relative to the device housing 24. Figure 2 and3 As shown, the actuator 50 is configured to move vertically relative to the device housing 24 along the longitudinal direction. Because the adjustable retaining element 60 engages with the actuator 50 on a first side of the adjustable retaining element and with the housing 24 on a second side of the adjustable retaining element, moving the actuator relative to the device housing 24 causes compression and deformation of the adjustable retaining element 60. Specifically, with Figure 2 Compared to the position of the actuator 50 shown, Figure 3 The position of the actuator 50 shown causes the first and second sides of the adjustable retaining element to be closer together. When the adjustable retaining element is in the retaining position, the distance between the first and second sides is reduced by 2.5 mm. This causes the adjustable retaining element to deform in the longitudinal direction.

[0226] The surface of the adjustable retaining element 60, defined between the channel inlet 62 and the channel outlet 64, has a convex curve shape. When the adjustable retaining element is in the retaining position, the curvature of this convex curve shape is greater. The inflection point of the convex curve shape defines the contraction of the channel. It is at this contraction of the adjustable retaining element 60 that the aerosol generating article 12, contained within the channel, contacts.

[0227] In the holding position, the adjustable holding element 60 is directly adjacent to the outer circumference of the aerosol generating article 12, allowing air to exit the cavity 10 only through the aerosol generating article 12. Air flows into the aerosol generating apparatus 1 through air inlet 36. More than one air inlet 36 may be provided. Air flows through the coil compartment 34. After exiting the coil compartment 34, air flows into the cavity 10 through air orifice 30 located at the bottom 28 of the cavity 10. Air then flows into the aerosol generating article 12 through gaps provided between the individual sensor blades. The adjustable holding element 60 is air-impermeable to prevent air from escaping from the cavity 10 except through the aerosol generating article 12. The adjustable holding element 60 completely surrounds the downstream end of the cavity 10.

[0228] Figure 4A perspective view of the adjustable retaining element 60, separate from the rest of the aerosol generating apparatus 1, is shown. The adjustable retaining element 60 is annular and has an annular shape. More specifically, the adjustable retaining element 60 includes two coaxially arranged rings 70, 71 connected by an annular, inwardly curved elastic material sheet 72. The coaxially arranged rings 70, 71 are integrally formed with the elastic material sheet 72. One of the coaxially arranged rings 70 is configured to engage the device housing 24. The other of the coaxially arranged rings 71 is configured to engage the actuating device 50. When the adjustable retaining element is in the received position, the gap between the two coaxially arranged rings 70, 71 is greater than the gap when the adjustable retaining element is in the held position. The actuating device 50 actuates the adjustable retaining element 60 by bringing one of the coaxially arranged rings closer to the other coaxially arranged ring. The deformation of the adjustable retaining element in the longitudinal direction and the radial contraction of the elastic material sheet 72 cause the channel 62 defined by the adjustable retaining element 60 to contract. The width and cross-sectional area of ​​the channel mentioned above were measured at this contraction.

[0229] Figures 5 to 7 This shows how the actuator 50 engages with the device housing 24. Figure 5 A perspective view of the distal end of the aerosol generating device, separate from the actuating device 50, is shown. A slot 80 is formed in the device housing 24. This slot 80 is configured to receive a connecting member of the actuating device. A corresponding slot is formed on the reverse side of the device housing 1. Figure 5 (Not shown in the image). The slot 80 includes a first end 82 and a second end 84. A locking portion 86 is formed in the second end 84 of the slot. The slot 80 is angled such that the first end 82 is closer to the distal end of the aerosol generating device than the second end 86.

[0230] Figure 6 A bottom view of the actuating device, separate from the aerosol generating device 1, is shown. Specifically, Figure 6 An actuator 50 is shown, comprising two engaging members in the form of pins 88 formed in a housing of the actuator 50. When the actuator members are properly assembled with the aerosol generating device, each pin 88 is received in a slot 80. The slot 80 then induces movement of the actuator 50 relative to the device housing 24.

[0231] The user of the aerosol generating device can rotate the actuator from a first position to a second position. In the first position, pin 88 is received in the first end 82 of the slot. In the second position, pin 88 is received in the second end 86 of the slot 80. Because the slot 80 is inclined in the longitudinal direction, pin 88 in the slot 80 leads the actuator 50 in the longitudinal direction (i.e., toward the cavity of the aerosol generating device 1). By moving the actuator in the longitudinal direction, the two coaxially arranged rings of the adjustable retaining element 60 are brought closer together. As described above, this causes the adjustable retaining element 60 to deform.

[0232] Figure 7 This is a schematic cross-sectional view of the distal end of an embodiment of the aerosol generating article 1 including a spring. The spring 90 is in contact with the device housing 24. Moving the actuator from a first position to a second position deforms the spring 90. The deformed spring causes the actuator 50 to return to the first position. When the actuator 50 is in the second position, such that the pin is located at the second end of the slot 80, the spring pushing the actuator 50 longitudinally pushes the pin 88 into the locking portion of the slot. Then, the action of the spring on the actuator retains the pin in the locking portion 86, preventing the actuator 50 from returning to the first position.

[0233] The user pushes the actuator along the longitudinal direction to push the pin out of the locking part 86. Then the actuator automatically returns to the first position by the action of the spring.

[0234] Alternatively, the actuator 50 is attached to the device housing 24 via a threaded and screw mechanism (not shown). This mechanism is configured such that rotation of the actuator 50 relative to the device housing 24 by the user of the device causes longitudinal movement of the actuator 50 relative to the device housing 24. The screw and thread mechanism is configured such that a 180-degree rotation of the actuator relative to the device housing 24 is sufficient to cause longitudinal movement of the actuator relative to the device housing by 2.5 mm.

[0235] Figure 8 One embodiment of an aerosol generating apparatus 800 is shown. (Compared to...) Figure 1 Similarly, only the distal portion of the aerosol generating device 800 is shown. The aerosol generating device 800 is shown schematically and in comparison with... Figure 1 , 2 It operates in the same manner as aerosol generation 1 shown in Figure 3. The only difference between aerosol generation 1 and aerosol generation 800 is the adjustable holding element.

[0236] The aerosol generating apparatus 800 includes an adjustable holding element 100. The adjustable holding element 100 includes a first element 102 and a second element 104. The first element 102 forms a first side of the adjustable holding element 100 and engages an actuating device. The second element 104 forms a second side of the adjustable holding element 100 and engages a device housing 24. Both the first element and the second element 102, 104 are formed of an elastic and resilient material. Both the first element and the second element 102, 104 are annular. The first element 102 is connected to the second element 104 at a connecting portion 105.

[0237] The operation of the adjustable holding element 100 is similar to Figure 1 , 2 The adjustable retaining element 60 shown in Figure 3 is actuated from the receiving position to the retaining position by the movement of the actuating device 50 relative to the device housing 24, so that the adjustable retaining element 100 is deformed.

[0238] When the adjustable retaining element 100 deforms, each of the first and second elements 102, 104 radially contracts. Each of the first and second elements 102, 104 defines a convex curve shape, and the curvature of each of these curves is greater when the adjustable retaining element 100 is in the retaining position. The inflection point of each curve defines a contraction portion in the channel 106 defined by the adjustable retaining element 100. Therefore, Figure 4 The adjustable holding element 100 defines two contraction portions. When the adjustable holding element 100 is in the holding position, these contraction portions each form a contact point with the aerosol generating article 12 housed in the channel 106. Thus, these contraction portions contact two separate portions of the aerosol generating article 12 that are spaced apart along the length of the aerosol generating article 12.
