Summary of the Invention

[0004] According to embodiments of the present invention, an aerosol generator may be provided which comprises an induction heating assembly. The induction heating assembly may comprise an induction coil and at least one electrical contact disposed to be in slidable contact with the induction coil. The aerosol generator may further comprise an air intake which may be configured to allow ambient air to be drawn into the aerosol generator. The aerosol generator may further comprise an inlet cover which may be configured to adjust the cross-sectional area of ​​the air intake. The aerosol generator may further comprise an actuation element. The actuation element may be mechanically connected to the electrical contact and the inlet cover. The actuation element may, in action, slide the contact along the induction coil and actuate the inlet cover to adjust the cross-sectional area of ​​the air intake.

[0005] According to embodiments of the present invention, an aerosol generator comprising an induction heating assembly is provided. The induction heating assembly comprises an induction coil and at least one electrical contact disposed to be slidably in contact with the induction coil. The aerosol generator further comprises an air intake configured to allow ambient air to be drawn into the aerosol generator. The aerosol generator further comprises an inlet cover configured to adjust the cross-sectional area of ​​the air intake. The aerosol generator further comprises an actuation element. The actuation element is mechanically connected to the electrical contact and the inlet cover. The actuation element is configured, upon operation, to slide the contact along the induction coil and to actuation cover to adjust the cross-sectional area of ​​the air intake.

[0006] Providing an electrical contact that can slide along the induction coil allows for partial activation of the induction coil. Partial activation of the induction coil allows for the creation of a variable-sized heating zone within the induction coil. Exemplary, the electrical contact can slide along the induction coil or between individual parts of the user during the operation of the aerosol generator, heating more aerosol-forming substrate over time. As a result, unused aerosol-forming substrate is heated during each smoke inhalation by the user. Therefore, the length of the heating zone may be gradually increased by sliding the contact along the induction coil.

[0007] By providing an inlet cover configured to adjust the cross-sectional area of ​​the air intake, the airflow allowed into the aerosol generator can be adjusted. Specifically, during use of the aerosol generator, the aerosol-forming substrate of the aerosol-generating article is gradually depleted. Therefore, it may be desirable to increase the airflow through the aerosol-generating article in order to maintain the amount of vaporized aerosol-forming substrate entrained and thus maintain satisfactory aerosol generation.

[0008] The combination of gradually increasing the cross-sectional shape of the air intake and sliding a slidable contact along the induction coil can be particularly beneficial. Sliding the slidable contact along the induction coil gradually increases the heating zone of the induction coil, thereby gradually heating more aerosol-forming substrate. At the same time, gradually increasing the cross-sectional shape of the air intake allows for additional airflow into the aerosol generator, thereby maintaining satisfactory aerosol generation.

[0009] The actuating element may be configured to slide a slidable contact in the proximal direction. The actuating element may be configured to increase the heating zone of the induction coil during the sliding of the slidable contact in the proximal direction.

[0010] The actuation element may be configured to slide the inlet cover in the proximal direction. The actuation element may be configured to increase the cross-sectional shape of the air intake port while the inlet cover is sliding in the proximal direction.

[0011] The inlet cover may be disposed on the outer circumference of the aerosol generator. Guide elements, preferably guide slots or guide projections, may be provided on the outer circumference of the aerosol generation division to facilitate the guided movement of the inlet cover. The guide elements may be disposed parallel to the longitudinal central axis of the aerosol generator.

[0012] The inlet cover may include a cover guide. The cover guide may be configured to be mounted on the guide element so that the inlet cover can slide relative to the guide element. Exemplary, the guide element may include a slot, and the cover guide may include a projection slidably disposed within the slot.

[0013] The induction coil may have a second electrical contact that may be fixedly connected to the induction coil.

[0014] A sliding contact may also be indicated as a first electrical contact or as a first sliding electrical contact. A second electrical contact may also be indicated as a second fixed electrical contact. One or both of the first electrical contact and the second fixed electrical contact may be connected to the power supply of the aerosol generator.

[0015] The inlet cover may be configured to slide on the outside of the air intake to adjust the cross-sectional area of ​​the air intake.

[0016] The inlet cover may have a circular shape. The air intake may have a circular cross-sectional shape. The outer diameter of the inlet cover may correspond to or be larger than the inner diameter of the air intake. In other words, the inlet cover may be sized to cover the air intake, thereby reducing or preventing airflow into the air intake. During the sliding movement of the inlet cover, the airflow into the air intake may be gradually enabled by the actuation element. Gradual activation of airflow into the air intake may be facilitated by the inlet cover gradually exposing the air intake during its sliding movement.

[0017] The air intake, as well as the inlet cover, may have alternative shapes. For example, the inlet cover may have an oval, elliptical, or rectangular shape. The air intake may have a corresponding oval, elliptical, or rectangular cross-sectional shape.

[0018] The inlet cover may be installed around the aerosol generator.

[0019] The actuation element may be configured as a sliding button. The actuation element may be configured to be operated by a user, more preferably by the user's finger.

[0020] The actuation element may be configured as an electrically actuated element. In this embodiment, the actuation element may be located within the aerosol generator. In other words, since the actuation element does not require manual activation in this embodiment, it may be protected from external influences by the housing of the aerosol generator.

[0021] The aerosol generator may further include a controller. The controller may be configured to control the sliding movement of electrically actuated elements based on the usage profile of the aerosol generator.

[0022] The controller may control the actuating element to slide the first contact in the proximal direction during the operation of the aerosol generating device. The controller may control the actuating element to slide the inlet cover in the proximal direction during the operation of the aerosol generating device. Preferably, the controller controls the actuating element to slide the first contact and the inlet cover simultaneously in the proximal direction.

[0023] The controller may be further configured to control the supply of electrical energy from a power source to one or both of the first electrical contact and the second electrical contact.

[0024] The aerosol generating device may further include a motor. The motor may be configured as an electric linear motor. The motor may be configured to slidably move an electrically actuated element. The controller may control the operation of the motor. The controller may be configured to control the supply of electrical energy from a power source for supplying power to the motor to the motor.

[0025] The actuating element may be disposed around the aerosol generating device.

[0026] The aerosol generating device may include an aerosol forming substrate and may further include a cavity configured to receive an aerosol generating article.

[0027] The induction coil may be disposed so as to at least partially surround the cavity.

[0028] The aerosol generating device may further include a power source, preferably a battery, for supplying power to the induction coil.

[0029] The present invention further relates to an aerosol generating system comprising an aerosol generating device as described herein and an aerosol generating article comprising an aerosol forming substrate.

[0030] The aerosol-generating article may comprise a susceptor configured to be heated by an alternating magnetic field generated by an induction coil of an aerosol-generating device.

[0031] The present invention further relates to a method of operating an aerosol-generating device as described herein. The method comprises the following steps:

[0032] sliding an electrical contact along an induction coil by an actuating element;

[0033] simultaneously actuating an inlet cover by the actuating element to adjust the cross-sectional area of an air inlet.

[0034] As used herein, the terms "proximal", "distal", "downstream", and "upstream" are used to describe the relative position of a component or portion of a component of an aerosol-generating device with respect to the direction in which a user inhales on the aerosol-generating device during use.

[0035] The aerosol-generating device may comprise a mouth-side end through which aerosol exits the aerosol-generating device and is delivered to the user during use. The mouth-side end may be referred to as the proximal end. During use, the user inhales on the proximal end or mouth-side end of the aerosol-generating device to inhale the aerosol generated by the aerosol-generating device. Alternatively, the user may directly inhale an aerosol-generating article inserted into an opening at the proximal end of the aerosol-generating device. The opening at the proximal end may be a cavity opening. The cavity may be configured to receive the aerosol-generating article. The aerosol-generating device comprises a distal end opposite the proximal end or mouth-side end. The proximal end or mouth-side end of the aerosol-generating device may also be referred to as the downstream end, and the distal end of the aerosol-generating device may also be referred to as the upstream end. Components of the aerosol-generating device, or portions of components, may be described as being upstream or downstream of one another based on their relative positions between the proximal end, downstream end, or mouth-side end of the aerosol-generating device and the distal end or upstream end of the aerosol-generating device.

[0036] As used herein, “aerosol generator” refers to a device that generates an aerosol by interacting with an aerosol-forming substrate. The aerosol-forming substrate may be part of an aerosol-generating article, for example, part of a smoking article. The aerosol generator may be a smoking device that interacts with the aerosol-forming substrate of an aerosol-generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol generator may be a holder. The device may be an electrically heated smoking device. The aerosol generator may comprise a housing, an electrical circuit, a power supply, a heating chamber, and an induction coil.

[0037] As used herein in relation to the present invention, the term “smoking” in relation to apparatus, articles, systems, substrates, or otherwise does not refer to conventional smoking in which the aerosol-forming substrate is completely or at least partially burned. The aerosol-generating apparatus of the present invention is configured to heat the aerosol-forming substrate to a temperature below the combustion temperature of the aerosol-forming substrate, but above the temperature at which one or more volatile compounds of the aerosol-forming substrate are released, in order to form an inhalable aerosol.

[0038] The aerosol generator may include an electrical circuit. The electrical circuit may include a microprocessor, which may be a programmable microprocessor. The microprocessor may be part of a controller. The electrical circuit may include further electronic components. The electrical circuit may be configured to regulate the supply of power to the induction coil. Power may be supplied to the induction coil continuously after the aerosol generator is started, or intermittently, such as with each inhalation. Power may be supplied to the induction coil in the form of current pulses.

[0039] The aerosol generator may have a power source, typically a battery, within the main body of the aerosol generator. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source may be a nickel-metal hydride battery, a nickel-cadmium battery, or a lithium-based battery (e.g., a lithium-cobalt battery, lithium iron phosphate, lithium titanate, or lithium polymer battery). Alternatively, the power source may be another form of charge storage device, such as a capacitor. The power source may require recharging and may have a capacity that allows for the storage of sufficient energy for one or more use experiences. For example, the power source may have sufficient capacity to continuously generate aerosols for a period of approximately 6 minutes, or a period of a multiple of 6 minutes. In another embodiment, the power source may have sufficient capacity to provide a predetermined number of fume extractions or discontinuous activations of the induction coil.

[0040] The cavity of the aerosol generator may have an open end into which an aerosol generating article is inserted. The open end may be the proximal end. The cavity may have a closed end opposite the open end. The closed end may be the base of the cavity. The closed end may be closed except for providing an air opening located within the base. The base of the cavity may be flat. The base of the cavity may be circular. The base of the cavity may be located upstream of the cavity. The open end may be located downstream of the cavity. The cavity may have an elongated extension. The cavity may have a longitudinal axis. The longitudinal axis may be a direction extending between the open end and the closed end along the longitudinal axis. The longitudinal axis of the cavity may be parallel to the longitudinal axis of the aerosol generator.

[0041] The cavity may be configured as a heating chamber. The cavity may have a cylindrical shape. The cavity may have a hollow cylindrical shape. The cavity may have a shape corresponding to the shape of the aerosol-generating article received inside the cavity. The cavity may have a circular cross-section. The cavity may have an elliptical or rectangular cross-section. The cavity may have an inner diameter corresponding to the outer diameter of the aerosol-generating article.

[0042] The airflow channel may extend through the cavity. Ambient air may be drawn through the airflow channel into the aerosol generator, into the cavity, and toward the user. Downstream of the cavity, a mouthpiece may be provided, or the user may inhale the aerosol generating article directly. The airflow channel may extend through the mouthpiece.

[0043] Generally, a susceptor is a material that has the ability to generate heat when penetrated by an alternating magnetic field generated by an induction coil. When located within an alternating magnetic field, if the susceptor is conductive, typically, eddy currents are induced by the alternating magnetic field. If the susceptor is magnetic, typically, another effect that contributes to heating is generally called hysteresis loss. Hysteresis loss arises mainly from the movement of magnetic domain blocks within the susceptor. This is because the magnetic orientations of these domains align with the alternating induction magnetic fields. Another effect that contributes to hysteresis loss is when magnetic domains expand or contract within the susceptor. Generally, all these changes occurring at or below the nanoscale within the susceptor are called "hysteresis loss" because they generate heat within the susceptor. Therefore, if the susceptor is both magnetic and conductive, both hysteresis loss and eddy current generation will contribute to the heating of the susceptor. If the susceptor is magnetic but not conductive, hysteresis loss becomes the only means by which the susceptor will be heated when penetrated by an alternating magnetic field. According to the present invention, the susceptor may be conductive or magnetic, or both conductive and magnetic. An alternating magnetic field generated by one or more induction coils heats the susceptor, which then transfers heat to the aerosol-forming substrate, thereby forming an aerosol. Heat transfer may also be mainly by conduction. Such heat transfer is best when the susceptor is in close thermal contact with the aerosol-forming substrate.

[0044] As used herein, the term “aerosol-generating article” refers to an article comprising an aerosol-forming substrate having the ability to release volatile compounds capable of forming aerosols. For example, an aerosol-generating article may be a smoking article that generates an aerosol that can be directly inhaled into the user's lungs through the user’s mouth. An aerosol-generating article may be disposable.

[0045] As used herein, the term “aerosol-forming substrate” refers to a substrate having the ability to release one or more volatile compounds that can form aerosols. Such volatile compounds may be released by heating the aerosol-forming substrate. Conveniently, the aerosol-forming substrate may be part of an aerosol-generating article or a smoking article.

[0046] The aerosol-forming substrate may be a solid aerosol-forming substrate. The aerosol-forming substrate may contain both solid and liquid components. The aerosol-forming substrate may contain a tobacco-containing material that contains volatile tobacco-flavored compounds released from the substrate upon heating. The aerosol-forming substrate may contain non-tobacco materials. The aerosol-forming substrate may contain an aerosol-forming agent that facilitates the formation of a high-density and stable aerosol. Examples of suitable aerosol-forming agents include glycerin and propylene glycol.

[0047] The aerosol generating substrate preferably comprises homogenized tobacco material, an aerosol forming body, and water. Providing homogenized tobacco material may improve aerosol generation and the nicotine content and flavor profile of the aerosol generated during heating of the aerosol generating article. Specifically, the process of producing homogenized tobacco involves a process of crushing tobacco leaves, which allows for more effective release of nicotine and flavor during heating.

[0048] Features described in relation to one embodiment may be equally applicable to other embodiments of the present invention.

[0049] The present invention will be further described with reference to the attached drawings, for illustrative purposes only. [Brief explanation of the drawing]

[Figure 1D] Figure 1D shows an exemplary aerosol generator. [Figure 1E] Figure 1E shows an exemplary aerosol generator. [Figure 2A] Figure 2A illustrates a further diagram of the aerosol generator. [Figure 2B] Figure 2B illustrates a further diagram of the aerosol generator. [Figure 2C] Figure 2C illustrates a further diagram of the aerosol generator. [Figure 2D] Figure 2D illustrates a further diagram of the aerosol generator. [Figure 3A] Figure 3A shows an embodiment of an aerosol generator with airflow control. [Figure 3B] Figure 3B shows an embodiment of an aerosol generator with airflow control. [Figure 3C] Figure 3C shows an embodiment of an aerosol generator with airflow control. [Figure 4A] Figure 4A shows an alternative embodiment of the aerosol generator. [Figure 4B] Figure 4B shows an alternative embodiment of the aerosol generator. [Modes for carrying out the invention]

[0051] Figure 1A shows an aerosol generator 10 having a cavity 12 configured to receive an aerosol generating article 14 comprising an aerosol-forming substrate. The aerosol generator 10 includes an induction coil 16 disposed to surround a portion of the cavity 12. The cavity 12 is configured as a heating chamber. The induction coil 16 is configured to inductively heat a susceptor 18. The susceptor 18 may be part of the aerosol generating article 14, or it may be disposed inside the induction coil 16 as part of the aerosol generator 10.

[0052] Figure 1B shows how the aerosol generating article 14 can be inserted into the cavity 12 of the aerosol generating device 10. Figure 1B also shows that the susceptor 18 is preferably disposed within the aerosol generating article 14. In this case, the susceptor 18 is preferably embedded within the aerosol forming substrate, such as by heating the substrate when exposed to an alternating magnetic field from the induction coil 16. The susceptor 18 may have a length corresponding to the length of the induction coil 16. The length of the susceptor 18 may be measured along the longitudinal axis of the aerosol generating article 14. The length of the induction coil 16 may be measured along the longitudinal axis of the aerosol generating device 10. The susceptor 18 may be flat. The susceptor 18 may be rectangular.

[0053] Figure 1B further illustrates the first and second electrical contacts. The first electrical contact is configured to slide along the induction coil 16. The second electrical contact is fixed. This allows for partial activation of the induction coil 16 by sliding the first contact 20 along the induction coil 16, as shown in Figures 1C to 1E. In these figures, the first contact 20 slides progressively along the induction coil 16, thereby gradually activating a larger portion of the induction coil 16. As a result, a gradually increasing heating zone is created inside the induction coil 16. As shown in Figures 1C to 1E, the corresponding larger portion of the susceptor 18 is heated. This consequently means that as the first contact 20 slides along the induction coil 16, more aerosol-forming substrate from the aerosol-generating article 14 is progressively heated.

[0054] Figure 2A shows an aerosol generating article 14 surrounded by an induction coil 16. A first contact 20 is positioned near a second contact 22, connected to the induction coil 16. Figure 2B shows the corresponding configuration of the aerosol generating article 14 inserted into the cavity 12 of the aerosol generator 10. In this embodiment, the sliding of the first contact 20 is facilitated by an actuation element 24. The actuation element 24 is depicted as a sliding button on the periphery of the aerosol generator 10. The same element is depicted in Figures 2C and 2D. However, the actuation element 24 is actuated, and more specifically, slides parallel to the longitudinal axis of the aerosol generator 10, to slide the first contact 20 along the induction coil 16. As a result, a larger heating zone is created within the induction coil 16, and a larger portion of the susceptor 18 of the aerosol generating article 14 is heated.

[0055] Figure 3 shows a preferred embodiment of the present invention. In this embodiment, the actuation element 24 has a dual function. In addition to the aforementioned function of the actuation element 24 in sliding the first contact 20 along the induction coil 16, the actuation element 24 further slides the inlet cover 26 relative to the air intake port 28. Preferably, the actuation element 24 is formed integrally with the inlet cover 26 such that the sliding movement of the actuation element 24 leads to the sliding movement of the inlet cover 26.

[0056] The air intake port 28 is fluidly connected to the cavity 12. During operation, a user inhaling the aerosol generating item 14 draws ambient air into the cavity 12 through the air intake port 28 and further through the aerosol-forming substrate of the aerosol generating item 14. The inlet cover 26 is positioned to gradually slide over the air intake port 28. In other words, the cross-section of the air intake port 28 can be adjusted by the sliding movement of the air intake port 28.

[0057] In Figure 3A, the first contact is positioned near the second contact 22. This is preferably the positioning before the start of the user experience. In this case, the air intake 28 is completely covered to prevent ambient air from flowing into the air intake 28. In Figure 3B, the user experience has started. The sliding movement of the actuating element moves the first contact 20 proximal along the induction coil 16, thereby increasing the portion of the induction coil 16 that is actuated. Simultaneously, the sliding movement of the actuating element 24 partially exposes the air intake 28 by sliding the inlet cover 26, also in a proximal direction. Finally, in Figure 3C, the air intake 28 is not completely covered, thereby maximizing the airflow into the cavity 12. At the same time, the full sliding movement of the actuating element 24 moves the first contact 20 to the proximal end of the induction coil 16, fully actinguating the induction coil 16, thereby heating the maximum amount of aerosol-forming substrate of the aerosol-generating article 14.

[0058] Figure 4A shows an alternative embodiment in which the third contact 30 is not provided as a sliding contact. Instead, the third contact 30 is provided as a fixed contact. In addition, a plurality of fourth contacts 32 are provided. All of the fourth contacts 32 are also fixed contacts. To activate different portions of the induction coil 16, the actuation element 24 is configured to connect either the third contact 30 or the fourth contact 32 to the power supply of the aerosol generator 10. An alternative example is shown in Figure 4B, where the plurality of fourth contacts 32 can be either positive or negative contacts, thereby not limiting the connection to a combination of the third contact 30 and any one of the fourth contacts 32. Instead, any desired combination of contacts can be chosen, for example, to activate only the middle portion of the induction coil 16 or to heat the subsequent segments of the induction coil 16. The embodiments of Figures 4A and 4B are preferably combined with simultaneously adjusting the inlet cover 26 as desired. For example, by progressively exposing the air intake port 28 with the operating element 24, a progressively larger amount of air may be allowed into the aerosol generator 10 during the user experience.
