Description

[Technical Field]

[0001] The present invention relates to an electrically operated aerosol generating system, and more particularly to an electrically operated aerosol generating system having an aerosol generating device and a charging device for receiving and charging the aerosol generating device. [Background technology]

[0002] An electrically operated aerosol generating system generally comprises an aerosol-forming substrate and an atomizer, the atomizer being operable to atomize a volatile compound in the aerosol-forming substrate to form an aerosol for inhalation by a user. Typically, an electrically operated aerosol generating system also comprises an aerosol generating device comprising a power supply for supplying power to the atomizer. The atomizer may be an electrically operated heating means, such as an electric heater.

[0003] In some systems, the aerosol-generating device is configured to receive an aerosol-generating article containing a solid aerosol-forming substrate, such as a substrate containing homogenized tobacco. In these systems, the device typically includes an atomizer configured to heat the aerosol-forming substrate when the article is received in the device. The article may also include a filter wound with an aerosol-forming substrate in the form of a rod similar to a conventional cigarette. In some systems, the aerosol-generating article may include a cartridge containing a liquid aerosol-forming substrate or a gel-like aerosol-forming substrate that can be heated by the atomizer. In some systems, the device may be configured to receive a cartridge containing both an atomizer and a liquid aerosol-forming substrate. Such cartridges are often referred to as cartomizers. A typical configuration of the atomizer used in a cartomizer includes a coil of heater wire wrapped around an elongated core immersed in a liquid aerosol-forming substrate.

[0004] Some electrically operated aerosol generating systems include a separate charging device for releasably holding and recharging the aerosol generating device when not in use. Such a charging device may also function as a case or holder and may provide some degree of protection for the aerosol generating device. The charging device may also provide additional functions such as data logging and recharging the aerosol generating device with an aerosol-forming substrate. Summary of the Invention [Problem to be solved by the invention]

[0005] Aerosol generating devices typically have a high aspect ratio, with a first longitudinal dimension being greater than the second and third width dimensions. Cases for holding aerosol generating devices often include a housing defining a narrow opening through which a user must insert the device. The narrow opening typically has a width similar to that of the aerosol generating device. To insert an aerosol generating device into these cases, a user must generally insert the aerosol generating device into the case by precisely aligning the aerosol generating device with the narrow opening and then sliding the aerosol generating device longitudinally into the case. This can be difficult for the user, especially in low light conditions or when the user is moving.

[0006] It would be desirable to provide an aerosol generation system that improves the speed and ease with which a user can insert an aerosol generating device into a compatible charging device and remove the aerosol generating device from the charging device. [Means for solving the problem]

[0007] An electrically operable aerosol generation system may be provided that includes a charging device having a primary power source and an elongated aerosol generation device having a secondary power source. The aerosol generation device is an elongated aerosol generation device having a proximal end, a distal end, and a body extending between the proximal and distal ends. The charging device has a docking arrangement configured to engage with the aerosol generation device for charging of the secondary power source by the primary power source. A first coupling member located on the body of the aerosol generation device is capable of engaging with a second coupling member located on a wall of the charging device.

[0008] The first and second connecting members may form a plug and socket connection, for example, the first and second connecting members may form a USB connection.

[0009] The coupling members may include electrical contacts that form an electrical connection, for example, allowing the secondary power source to be charged by the primary power source. Thus, the first coupling member may include a first electrical contact and the second coupling member may include a second electrical contact engageable with the first electrical contact.

[0010] The coupling member may include a data contact, for example, to enable data transfer between the aerosol generating device and the charging device. Thus, the first coupling member may include a first data contact and the second coupling member may include a second data contact engageable with the first data contact.

[0011] The charging device has a docking arrangement configured to engage the aerosol generating device, the docking arrangement including a docking space defined between a first end and an opposite second end spaced from and fixed relative to the first end, the docking space corresponding to a longitudinal dimension of the elongated aerosol generating device between the first and second ends.

[0012] Preferably, at least a portion of the aerosol generating device remains exposed when the aerosol generating device is engaged with the charging device, for example, at least one side of the body of the aerosol generating device may be exposed when the aerosol generating device is engaged with the charging device, forming an exterior surface of the aerosol generating system.

[0013] Engagement between the aerosol generating device and the docking arrangement is preferably achieved by relative movement of the aerosol generating device and the receiving portion in a direction perpendicular or substantially perpendicular to the longitudinal axis of the aerosol generating device. The aerosol generating device may engage with the charging device such that a side of the body of the aerosol generating device abuts an outer surface of the charging device. The aerosol generating device may or may not be engaged with the charging device such that the aerosol generating device is positioned within a docking space defined between a first end and an opposite second end spaced from and fixed relative to the first end, the docking space corresponding to the longitudinal dimension of the elongated aerosol generating device between the first and second ends.

[0014] The first end and the second end preferably form part of the charging device, for example, part of the housing of the charging device. The first end and the second end may be walls of the housing of the charging device. The first end and the second end may be members extending from the housing of the charging device. The docking space is preferably at least partially external to the charging device. For example, the docking space may be open to the environment external to the charging device when the aerosol generating device is not housed within the docking space.

[0015] The charging device preferably includes a housing for holding a primary power source. The primary power source may be, for example, a rechargeable battery held by or within the housing of the charging device. When the aerosol generating device is accommodated by the docking space, engagement between the charging device and the aerosol generating device preferably allows the secondary power source of the aerosol generating device to be charged by the primary power source of the charging device. For example, electrical contacts located on the aerosol generating device may be arranged to engage with corresponding electrical contacts located on the charging device when the aerosol generating device is engaged with the docking arrangement.

[0016] As used herein, the term "aerosol-generating device" refers to a device that interacts with an aerosol-forming substrate to generate an aerosol that can be inhaled directly into the user's lungs through the user's mouth. In certain embodiments, the aerosol-generating device may heat the aerosol-forming substrate to promote the release of volatile compounds. The aerosol-generating device may interact with an aerosol-generating article that includes the aerosol-forming substrate, or a cartridge that includes the aerosol-forming substrate. An electrically operated aerosol-generating device may include an atomizer, such as an electric heater, for heating the aerosol-forming substrate to form an aerosol.

[0017] As used herein, the term "aerosol-generating article" refers to an article that includes an aerosol-forming substrate capable of releasing a volatile compound that can form an aerosol. In certain embodiments, an aerosol-generating article may comprise an aerosol-forming substrate that, upon heating, is capable of releasing a volatile compound that can form an aerosol.

[0018] As used herein, the terms "upstream," "downstream," "proximal," and "distal" are used to describe the relative positioning of components or portions of components of the aerosol generating device, the aerosol-generating article, and the case.

[0019] As used herein, the term "longitudinal" is used to describe the direction between the downstream, proximal, or oral end and the opposite upstream or distal end, and the term "transverse" is used to describe the direction perpendicular to the longitudinal direction.

[0020] As used herein, the term "length" is used to describe the maximum longitudinal dimension between the distal or upstream end and the proximal or downstream end of a component, aerosol generating device, aerosol-generating article, and casing.

[0021] As used herein, the term "diameter" is used to describe the largest transverse dimension of components, such as aerosol generating devices and aerosol-generating articles.

[0022] As used herein, the term "transverse cross section" is used to describe a cross section of a component, an aerosol generating device, an aerosol generating article, and a charging device in a direction perpendicular to the major axis of the component, the aerosol generating device, the aerosol generating article, and the case, respectively.

[0023] As used herein, the term "exposed" is used to indicate that a portion of a feature or component is open to the external environment and is not enclosed or covered.

[0024] The term "magnetic material" is used herein to describe a material that can interact with a magnetic field, including both paramagnetic and ferromagnetic materials. A magnetizable material may be a paramagnetic material, such that it remains magnetized only in the presence of an external magnetic field. Alternatively, a magnetizable material may be a material (e.g., a ferromagnetic material) that becomes magnetized in the presence of an external magnetic field and remains magnetized after the external magnetic field is removed. As used herein, the term "magnetic material" includes both types of magnetizable materials, as well as materials that are already magnetized.

[0025] The elongated aerosol-generating device is configured to generate an inhalable aerosol from an aerosol-forming substrate. The elongated aerosol-generating device article may be substantially cigarette- or cigar-shaped. For example, the elongated aerosol-generating device may have a first longitudinal or length dimension that is greater than second and third width dimensions. While the second and third dimensions are sometimes referred to as width and thickness, the second and third dimensions are preferably substantially identical and therefore may both be referred to as width. The elongated aerosol-generating device may be substantially cylindrical. The longitudinal dimension defines a longitudinal axis. The width dimension extends perpendicular to the longitudinal axis. The elongated aerosol-generating device may be described as having a proximal end and a distal end and comprising an elongated body defined between the proximal and distal ends. The body may have at least one side extending between the proximal and distal ends.

[0026] The docking space may be further defined by a rear portion extending between the first end and the second end. Thus, the docking space may be at least partially defined by the first end, the second end, and the rear portion. The rear portion may be a rear wall. The rear portion may be part of an outer wall of the housing of the charging device.

[0027] The aerosol generating device may be easily engaged and disengaged with the docking arrangement by movement perpendicular to the longitudinal axis of the aerosol generating device, which is a movement transverse to the aerosol generating device. The aerosol generating device may be easily engaged and disengaged with the docking arrangement by movement into the docking space in a direction substantially perpendicular to the longitudinal axis of the aerosol generating device. For example, either the proximal or distal end of the aerosol generating device may be inserted into the docking space for engagement with the charging device. The opposite end may then be pivoted into the docking space so that the aerosol generating device fully engages with the charging device. By using a perpendicular or substantially perpendicular movement, the distance that must be traveled to engage the aerosol generating device with the charging device is shorter than in typical systems that accept the aerosol generating device when inserted longitudinally into the charging device. If present, the opening to the docking space corresponds to the longitudinal dimension of the aerosol generating device. It is therefore easier to position the aerosol generating device within the docking space than if the docking space were sized to correspond only to the transverse dimensions of the aerosol generating device.

[0028] The docking space may at least partially form an open channel within the housing of the charging device. Thus, the docking space may be at least partially defined by a first side wall, a second side wall, a rear wall, and first and second ends. The open channel may be an elongated recess or slot defined by the housing of the charging device. The elongated aerosol generating device may be fully received within the open channel, with no portion of the aerosol generating device extending beyond the peripheral boundary of the charging device. Alternatively, the elongated aerosol generating device may be only partially received within the open channel. In this case, a portion of the aerosol generating device, sometimes referred to as the exposed portion, extends beyond the peripheral boundary of the charging device.

[0029] It may be advantageous for a portion of the aerosol generating device to form an exterior surface of the system when the aerosol generating device is engaged with the charging device. For example, it may be advantageous for at least one side of the body of the aerosol generating device to form an exterior surface of the system when the aerosol generating device is engaged with the charging device. The aerosol generating device may be easily removed by a user, who simply grasps the exposed portion of the aerosol generating device to detach the aerosol generating device from the charging device. The exposed portion of the aerosol generating device may have a shape that matches or corresponds to the shape of the housing of the charging device. The charging device may have a shaped or contoured housing, and the aerosol generating device also has a housing or exterior surface that is configured to match the shape or contour of the charging device housing when the aerosol generating device is engaged with the charging device. The aerosol generating device may act to close or cover an open groove in the charging device. Therefore, features of the charging device, such as a display, indicator, contact, or button located in such an open groove, may be shielded from the external environment when the aerosol generating device is engaged with the charging device. In this way, the display, indicators, contacts or buttons may be protected when the aerosol generating device is engaged with the charging device, for example during transport.

[0030] In some embodiments, the first end and the second end are located on protrusions extending from the housing of the charging device, e.g., first and second protrusions extending from the housing. The protrusions may be referred to as lugs. Thus, the longitudinal dimension of the docking space may be defined between opposing first and second ends located on the first and second protrusions. The docking space may not be constrained in any other dimension. Alternatively, the docking space may be further constrained by a rear wall extending between the first and second protrusions. The docking space may be even further constrained by one or more side walls extending between the first and second protrusions.

[0031] The docking space is preferably configured to receive the aerosol generating device when the aerosol generating device is forced into the docking space in a direction perpendicular to the long dimension of the aerosol generating device, and therefore, when engaged with the charging device, the long dimension of the aerosol generating device is preferably parallel to a side or edge of the charging device.

[0032] The docking arrangement may include latching means, such as a mechanical latch, for releasably holding the aerosol generating device in engagement with the docking arrangement. For example, a latching protrusion may extend from the charging device and be configured to engage a side wall of the aerosol generating device.

[0033] The latching means may comprise one or more magnets. For example, the docking arrangement may comprise a magnetic latch for releasably holding the aerosol generating device in engagement with the docking arrangement. The one or more magnets may be located on the charging device. The aerosol generating device would then include one or more portions that are magnetically attracted to the one or more magnets for holding the aerosol generating device engaged with the charging device when the aerosol generating device is aligned within the docking arrangement.

[0034] Latching magnets may be included on both the charging device and the aerosol generator. A magnet on one of the charging device and the aerosol generator may exhibit a north pole, and a corresponding magnet on the other of the charging device and the aerosol generator may exhibit a south pole. The aerosol generator may include a pair of magnets spaced apart longitudinally, and the charging device may include a corresponding pair of magnets arranged to latch with the pair of magnets on the aerosol generator. The pair of longitudinally spaced magnets may be referred to as first and second aerosol generator magnets, and the pair of corresponding magnets may be referred to as first and second charging device magnets. The magnet of the first aerosol generator may be located at or near the proximal end of the aerosol generator. The magnet of the second aerosol generator may be located at or near the distal end of the aerosol generator. Both the magnets of the first and second aerosol generators may have north polarity, in which case both the magnets of the first and second charging device will have south polarity. If the magnets of the first and second aerosol generators both have south polarity, then the magnets of the first and second charging devices both have north polarity. If the magnets of the first and second aerosol generators are spaced symmetrically about the longitudinal midpoint of the aerosol generators, this arrangement may allow the aerosol generators to latch with the charging devices in either longitudinal orientation. In one arrangement, the magnet of the first aerosol generator may present north polarity and the magnet of the second aerosol generator may present south polarity. In this case, the magnet of the first charging device will present south polarity and the magnet of the second charging device will present north polarity. This configuration allows the aerosol generators to latch with the charging devices when the aerosol generators are presented in a configuration in which the magnet of the first aerosol generator is aligned with the magnet of the first charging device, but latching will not occur when the aerosol generators are presented in a configuration in which the magnet of the first aerosol generator is aligned with the magnet of the second charging device. This may advantageously ensure that latching only occurs in a particular longitudinal orientation, which is sometimes called magnetic keying.

[0035] The magnet used in the latch is preferably a strong magnet, such as a rare earth magnet (e.g., a neodymium iron boron (NdFeB) magnet), small enough in size to hold the aerosol generating device and charging device.

[0036] The aerosol generating device may be held in engagement with the charging device by interference. For example, a distal end of the aerosol generating device may engage with a first end, a proximal end of the aerosol generating device may engage with a second end, and frictional engagement between the opposing ends of the device and the first and second ends of the charging device holds the aerosol generating device in engagement with the charging device. A biasing means, such as a spring, may be located on or at either end of the aerosol generating device to help provide interference when the aerosol generating device and the charging device are engaged. The biasing means may also provide pressure between contacts located on the aerosol generating device and contacts located on the charging device to help increase the reliability of these contacts during engagement between the aerosol generating device and the charging device.

[0037] The aerosol generating device may include charging contacts located on a sidewall of the aerosol generating device, e.g., near the distal end or near the proximal end of the sidewall of the device, and the charging device may include corresponding charging contacts. The charging contacts may be configured as circumferential rings that substantially or completely surround one or more body portions of the aerosol generating device, e.g., near the distal end of the aerosol generating device. Thus, the body of the aerosol generating device may include first and second longitudinally spaced circumferential electrical contacts, the first electrical contact being a positive contact and the second electrical contact being a negative contact. Corresponding contacts may be defined on the charging device to enable electrical coupling between the aerosol generating device and the charging device.

[0038] The charging contacts may be symmetrically disposed on the body of the aerosol generating device. For example, a first charging contact may be located at the midpoint of the body of the aerosol generating device between the proximal and distal ends. Additional contacts may be equidistantly spaced distally and proximally such that one of the contacts aligns with a corresponding contact on the charging device regardless of the longitudinal orientation in which the aerosol generating device is engaged with the charging device. Similarly, the charging contacts may be symmetrically disposed on the body of the aerosol generating device such that one of the contacts aligns with a corresponding contact on the aerosol generating device regardless of the longitudinal orientation in which the aerosol generating device is engaged with the charging device.

[0039] The charging contacts may enable data transfer between the aerosol generating device and the charging device as well as charging of the secondary power source. Alternatively, one or more dedicated data transfer contacts may be defined on the aerosol generating device and the charging device to enable data transfer between the devices.

[0040] Charging contacts or data contacts defined on the body of the aerosol generating device or charging device may serve dual functions. For example, a contact may serve as both a charging contact and a user-operable button for activating a feature or function. For example, a charging contact on the body of the aerosol generating device may engage a corresponding contact to enable electrical communication between the aerosol generating device and the charging device. The same charging contact may also serve as an operating button when the aerosol generating device is not engaged with the charging device, for example, to activate a heating cycle and generate aerosol. The charging contact may sense an electrical charge on the user's skin to function as a button.

[0041] The aerosol generation system can be, for example, Bluetooth (registered trademark) It may also include a wireless data transfer means such as a connection.

[0042] The aerosol generation system may be configured so that the aerosol generation device can be charged in either longitudinal orientation in which the aerosol generation device is engaged with the charging device.

[0043] The system may also be configured so that any data connection between the aerosol generating device and the charging device can be made regardless of the orientation of engagement.

[0044] Advantageously, the aerosol generating device may be provided with one or more status indicators (such as status lights) extending circumferentially around the aerosol generating device. Status information may therefore be determined by a user without having to search the device for the correct orientation to view the status indicators. It may be particularly advantageous for the status indicators to be visible whatever the radial orientation in which the aerosol generating device is engaged with the charging device. Status information may therefore be visible during charging without the need to specifically orient the aerosol generating device.

[0045] A preferred status indicator may comprise two or more longitudinally spaced lights on the aerosol generating device, each extending circumferentially around the device. Each light may indicate the status of a different parameter. Progression of a status, such as battery charge level, may be indicated by illuminating more or less light. Each separate indicator light may comprise a circumferentially spaced ring of LEDs. Each separate indicator light may be a ring-shaped LED extending circumferentially around the aerosol generating device.

[0046] The aerosol generating device may include one or more user-actuable buttons located on a first sidewall of the aerosol generating device. The aerosol generating device may include one or more displays located on a first sidewall of the aerosol generating device. The aerosol generating device may include one or more contacts (such as electrical or data contacts) located on a first sidewall of the aerosol generating device. The aerosol generating device may include any combination of user-actuable buttons, displays, and contacts (such as electrical or data contacts) located on a first sidewall of the aerosol generating device. The system may advantageously be configured such that the first sidewall faces the charging device when the aerosol generating device is coupled to the charging device. For example, the docking arrangement may be configured such that the first sidewall faces the charging device when the aerosol generating device is positioned within the docking space. In this configuration, the aerosol generating device is radially oriented in a specific orientation for engagement with the charging device. Such orientation may be achieved by a keying means that prevents the aerosol generating device from engaging with the charging device in any orientation other than the desired orientation. The advantage of such an orientation is that buttons on the aerosol generating device can be protected from accidental activation when the aerosol generating device is mated with the charging device. Similarly, any display can be protected from accidental damage when the aerosol generating device is mated with the charging device. Furthermore, any contacts can be aligned with corresponding contacts on the charging device.

[0047] Preferably, at least a portion of the aerosol generating device remains exposed when the aerosol generating device is engaged with the charging device. For example, at least one side wall (e.g., at least one outer side wall) of the aerosol generating device remains exposed to the external environment when the aerosol generating device is engaged with the charging device. To facilitate engagement and disengagement of the aerosol generating device from the charging device, a user may be able to more easily grasp the exposed surface of the at least one outer side wall. A user may be able to grasp and apply pressure to the exposed surface to detach the aerosol generating device from the charging device. The aerosol generating device may therefore be easier to remove from engagement with the charging device. Preferably, the at least one outer side wall does not have any user-operable buttons, displays, or contacts located thereon. When the cross-section of the aerosol generating device approximates a circle, the at least one outer side wall may encompass at least 180 degrees of the circumference of the circle, for example, at least 240 degrees, or at least 250 degrees, or at least 260 degrees, or at least 270 degrees of the circumference of the circle. The remainder of the circumference of the circle comprises the first sidewall of the aerosol generating device. When the aerosol generating device is engaged with the charging device, at least 4 mm of the diameter of the aerosol generating device may remain exposed. This exposed portion may provide a surface for a user to grip the aerosol generating device. Preferably, at least 5 mm (e.g., at least 6 mm, or at least 7 mm, or at least 8 mm, or at least 9 mm, or at least 10 mm) of the diameter of the aerosol generating device remains exposed when the aerosol generating device is engaged with the charging device.

[0048] The charging device may define a docking space that is an open channel at least partially defined by a first side wall, a second side wall, a rear wall, and a first end and a second end. A portion of the first side wall, the second side wall, or both the first and second side walls may be partially cut away to further expose the aerosol generating device. Such cut-out wall portions may facilitate the engagement and detachment of the aerosol generating device from the charging device by increasing the exposed surface area of ​​the aerosol generating device in the area of ​​the cut-out wall portions.

[0049] It is preferred that one or more user-actuable buttons, one or more displays, or one or more contacts (such as electrical or data contacts) are not exposed when the aerosol generating device is engaged with the charging device to protect them from accidental activation.

[0050] The aerosol generating device may include a mouthpiece at its proximal end. The mouthpiece may thus directly engage with either the first end or the second end of the docking arrangement. The mouthpiece may include the proximal end of the aerosol generating device and a portion of the body of the aerosol generating device extending toward the distal end of the aerosol generating device. The mouthpiece preferably includes a channel for the passage of aerosol generated by the aerosol generating device, e.g., a channel having an opening defined at the proximal end of the aerosol generating device so that the aerosol can be drawn into the user's mouth by sucking on the mouthpiece.

[0051] The mouthpiece may include one or more electrical or data contacts configured to contact corresponding electrical or data contacts located on the charging device. The mouthpiece may include means for facilitating docking of the aerosol generating device to the charging device. For example, the mouthpiece may include an indentation, recess, slot, or groove for receiving a movable protrusion located on the charging device to mechanically latch the aerosol generating device and the charging device. Similarly, the mouthpiece may include a movable protrusion for interacting with an indentation, recess, slot, or groove located on the charging device to mechanically latch the aerosol generating device and the charging device.

[0052] The mouthpiece may be a separable mouthpiece that can be removably separated from the aerosol generating device. This may facilitate cleaning of the mouthpiece. Furthermore, a separable mouthpiece may allow access to an internal portion of the aerosol generating device. This may be desirable, for example, to replace an aerosol-forming substrate located within the aerosol generating device. The aerosol-forming substrate may be located or contained within the separable mouthpiece so that a replacement mouthpiece can be provided to replenish the aerosol-forming substrate.

[0053] The aerosol generating device may comprise a replaceable substrate section containing the aerosol-forming substrate. The replaceable substrate section may form part of the body of the aerosol generating device and may itself position or contain a portion of the aerosol-forming substrate for consumption within the device. The replaceable substrate section may be located distal to the proximal end of the device, for example distal to the mouthpiece. The replaceable substrate section may be located proximal to the distal end of the device. The replaceable substrate section may be connected to one or more other sections forming the body of the aerosol generating device by connecting means such as a screw thread, or a bayonet joint, or a magnetic connection, or a mechanical latching means (such as a snap fit or an interference fit).

[0054] The replaceable substrate section may comprise a reservoir of a liquid aerosol-forming substrate. For example, the replaceable substrate section may comprise a reservoir of a liquid comprising nicotine and an aerosol former (such as propylene glycol or glycerin). Alternatively, the replaceable substrate section may comprise a reservoir of a solid aerosol-forming substrate or a reservoir of a colloidal aerosol-forming substrate, such as a gel substrate.

[0055] The aerosol generating device may comprise a replaceable base section containing two or more components that when combined form an aerosol.

[0056] The replaceable substrate section may include an atomizer, such as a heating element, for heating the aerosol-forming substrate or for heating at least one of two or more components that, when combined, form an aerosol. Thus, the replaceable substrate section may be in the form of an atomizer and may include both the aerosol-forming substrate and the atomizing component. In such embodiments, the replaceable substrate section preferably includes electrical contacts configured to contact corresponding electrical contacts on a battery portion of the aerosol generating device to provide power for operation of the atomizer.

[0057] In a preferred embodiment, the atomizer may be a resistive heater such as a resistive wire or a resistive track on a substrate. In another embodiment, the atomizer may be an induction susceptor that has the ability to heat when in a varying magnetic field generated by an induction coil.

[0058] In another preferred embodiment, the aerosol-generating device may comprise a substrate-receiving recess for receiving a consumable aerosol-generating article comprising an aerosol-forming substrate. Examples of aerosol-generating articles include sachets filled with solid aerosol-forming substrates, cigarettes and cigarette-like articles comprising an aerosol-forming substrate contained within a wrapper such as cigarette paper, capsules or containers of liquid or colloidal aerosol-forming substrates, etc. The consumable aerosol-generating article may comprise interchangeable substrate sections containing two or more components that, when combined, form an aerosol.

[0059] The consumable aerosol-generating article may include an atomizer, such as a heating element, for heating an aerosol-forming substrate or for heating at least one of two or more components that, when combined, form an aerosol. Thus, the consumable aerosol-generating article may be in the form of an atomizer or may include both an aerosol-forming substrate and an atomizer component. In such embodiments, the consumable aerosol-generating article preferably includes electrical contacts configured to contact corresponding electrical contacts on a battery portion of the aerosol generating device to provide power for operation of the atomizer.

[0060] In embodiments, the atomizer may be a resistive heater, such as a resistive wire or a resistive track on a substrate, hi other embodiments, the atomizer may be an induction susceptor that has the ability to heat when in a varying magnetic field generated by an induction coil.

[0061] A preferred consumable aerosol-generating article may be in the form of a cigarette or cigarette-like article comprising a solid aerosol-forming substrate contained within a wrapper. Such an article preferably comprises a mouth end intended to be inserted into a user's mouth for consumption of the article. The mouth end preferably comprises a filter that mimics a conventionally prepared cigarette. The consumable aerosol-generating article is preferably configured to interact with an atomizer, preferably a heater, located within the body of the aerosol-generating device. Thus, a heating means, such as a resistive heating element, may be located within or around a substrate-receiving recess for receiving the consumable aerosol-generating article. The substrate-receiving recess may be located at the proximal end of the device. For example, an opening to the substrate-receiving recess may be located at the proximal end of the device.

[0062] The aerosol-generating device may include a heating element for heating the consumable aerosol-generating article. The heating element may be an internal heater designed to be inserted into the consumable aerosol-generating article, such as a resistance heating element, or a susceptor in the form of a pin or blade that can be inserted into an aerosol-forming substrate located within the consumable aerosol-generating article. The heating element may be an external heater designed to heat the exterior surface of the consumable aerosol-generating article, such as a resistance heating element, or a susceptor located around or surrounding a substrate-receiving recess for receiving the consumable aerosol-generating article.

[0063] It may be advantageous for the aerosol generating system to include two or more aerosol-generating articles. It may further be advantageous for the aerosol generating system to have the ability to simultaneously hold or charge two or more aerosol generating devices. An electrically operable aerosol generating system may be provided in which the docking arrangement is a first docking arrangement and the charging device further comprises a second docking arrangement configured to engage with the aerosol generating device. The second docking arrangement comprises a third coupling member for engaging with the first coupling member located on the aerosol generating device.

[0064] A system may be provided in which the docking arrangement is a first docking arrangement including a first docking space, and the charging device further comprises a second docking arrangement configured to engage with the aerosol generating device.

[Figure 2] FIG. 2 shows a schematic diagram of an electrically operated aerosol generation system according to a particular embodiment of the present invention.

[Figure 4] FIG. 4 shows a schematic diagram of an electrically operated aerosol generation system according to a particular embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0089] 1 shows a schematic diagram of a known electrically operated aerosol generating system, which comprises a charging device 1, an aerosol generating device 20, and an aerosol-generating article 30.

[0090] The charging device 1 includes a housing 2 having the general size and shape of a conventional cigarette packet. A lithium-ion battery 3 and electrical circuitry 4 are housed within the charging device 1. The charging device 1 further includes a generally circular, cylindrical recess 5 for receiving an aerosol-generating device 20. The recess 5 is defined by the housing 2. A first electrical connector portion (not shown) is disposed at the closed end of the recess 5 for electrically connecting an aerosol-generating device received within the recess 5 to the battery 3 of the charging device 1.

[0091] The aerosol-generating device 20 is substantially circular and cylindrical and has the general dimensions of a conventional cigar. The length of the device 20 is substantially the same as the length of the recess 5, and the diameter of the device 20 is slightly smaller than the diameter of the recess 5 so that the device 20 fits closely within the recess 5. The aerosol-generating device 20 includes an open recess 21 at its proximal end for receiving an aerosol-generating article. The aerosol-generating device 20 further includes a battery (not shown) housed in the device housing and an electric heater (not shown) disposed within the recess 21 for heating at least a portion of the aerosol-generating article 30 when the aerosol-generating article 30 is received within the recess 21.

[0092] The aerosol-generating article 30 includes an aerosol-forming substrate (not shown) comprising an aggregate of crimped sheets of tobacco, and a filter (not shown) disposed back-to-back with the rod-shaped aerosol-forming substrate. The aerosol-generating article 30 has a diameter substantially equal to the diameter of the cavity 21 of the device 20 and a length greater than the cavity 21, so that when the aerosol-generating article 30 is received in the cavity 21 of the device 20, the filter extends outside the cavity 21 and can be drawn on by a user, similar to a conventional cigarette.

[0093] In use, the user inserts article 30 into cavity 21 of device 20 and turns on device 20, activating the electric heater. The electric heater heats the aerosol-forming substrate of article 30 so that volatile compounds in the aerosol-forming substrate are released and atomized to form an aerosol. The user draws on the mouthpiece of article 30 and inhales the aerosol generated from the heated aerosol-forming substrate.

[0094] After use of device 20, item 30 may be removed from device 20 for disposal, and device 20 may be placed into charging device 1 for storage and to charge the battery of device 20. To place item 30 into charging device 1, the longitudinal axis of device 20 must be closely aligned with the longitudinal axis of cavity 5 of charging device 1. When device 20 is aligned with cavity 5, the distal end of device 20 may be inserted into the open end of cavity 5. In some embodiments, a lid is provided to close the open end of the cavity and retain device 20 within cavity 5.

[0095] 2 provides a schematic diagram of a particular embodiment of an electrically operated aerosol generation system. The system includes a charging device 201, an aerosol generation device 220, and an aerosol-generating article 230.

[0096] The charging device 201 includes a housing 202 that is approximately the same size and shape as a conventional packet of cigarettes. The housing 202 positions and holds a lithium-ion battery 203. This battery 203 may be referred to as the system's primary power source or primary battery. The primary battery 203 is electrically connected to a charging port 213, allowing the primary battery 203 to be recharged from an external power source (such as a mains power source). The charging device further includes a docking arrangement that includes a docking space 205 defined between a first end 206 and an opposite second end 207 that is spaced from and secured relative to the first end 206. The docking space is further defined by a rear wall 208 and first and second side walls (not shown), forming an elongated docking space 205 with a longitudinal axis extending between the first end 206 and the second end 207. The first end 206, the second end 207, the rear wall 208, the first side wall, and the second side wall are part of the housing 202. The docking space is not closed by a cover or lid and forms an open groove in the housing 202 of the charging device 201. The first electrical contact 217 and the second electrical contact 218 are positioned by the rear wall 208 and face into the docking space 205. The first electrical contact and the second electrical contact are electrically connected to the primary battery 203. The charging device further includes an electrical circuit, such as at least one microprocessor, for controlling charging and discharging of the primary battery 203.

[0097] The aerosol generating device has a substantially cylindrical, elongated housing 222 having a proximal end 223, a distal end 224, and a body 225 extending between the proximal and distal ends 223, 224. The length of the device 220 is substantially the same as the length of the longitudinal dimension of the docking space 205. A first device contact 227 and a second device contact 228 are located between the proximal and distal ends by the body 225. The first and second device contacts are electrically connected to a device battery 226, allowing for recharging of the device battery 226. The device battery 226, which may be referred to as a secondary power source or secondary battery, may be any suitable battery, such as a lithium-ion battery or a lithium iron phosphate battery.

[0098] A substrate-receiving recess 221 is defined in the proximal portion of the device 220 for receiving an aerosol-generating article including an aerosol-forming substrate. The recess 221 is substantially cylindrical and has an opening defined in the proximal end of the device. A heating element positioned around the interior wall 229 of the substrate-receiving recess 221 is electrically connected to the device battery 226 and acts to heat the recess. In an alternative embodiment, the heating element may be defined on a heating element, such as a pin or blade, positioned within the recess for insertion into the aerosol-generating article. In other embodiments, an induction coil may be positioned around the wall 229 of the recess 221 to inductively heat a susceptor within the recess 221 or within an aerosol-generating article inserted into the recess.

[0099] Electronic circuitry, including a microprocessor, is included within the aerosol generating device to control the charging of the device battery 226 and the operation of the heating means.

[0100] The aerosol-generating article 230 is a cylindrical article comprising multiple components (including an aerosol-forming substrate 231 and a mouthpiece filter 232) assembled within cigarette paper 233. The article 230 has a distal end 234 and a proximal end 235 or mouth end located downstream from the distal end 234. The aerosol-forming substrate 231 is preferably in the form of an assembly of homogenized tobacco material sheets and is located at or near the distal end 234 of the article 230. Additional components, such as aerosol-cooling elements, flavor elements, and spacing elements, may be positioned within the article 230 between the aerosol-forming substrate 231 and the mouthpiece filter 232.

[0101] The aerosol generating device 220 has a longitudinal dimension that is approximately the same length as the longitudinal dimension of the docking space 205. The aerosol generating device 220 may be engaged with the charging device 210 by aligning the longitudinal axis of the aerosol generating device 220 with the longitudinal axis of the docking space 205, with the proximal end 223 of the aerosol generating device 220 adjacent to the first end 206 of the docking arrangement, and with the distal end 224 of the aerosol generating device 220 adjacent to the second end 207 of the docking arrangement. The aerosol generating device may then be moved into engagement by translation into the docking space 205, a movement perpendicular to the longitudinal axis of the aerosol generating device 220. The proximal end 223 of the aerosol generating device 220 engages with the first end 206, and the distal end 224 of the aerosol generating device 220 engages with the second end 207. The first contact 217 and the second contact 218 are aligned with and in electrical contact with the first device contact 227 and the second device contact 228. The aerosol generating device may be held in engagement by an interference fit or a frictional engagement. Alternatively, mechanical latching means may be automatically or manually operated to hold the aerosol generating device engaged with the charging device. For example, the latching means may extend from the rear wall and engage the body of the aerosol generating device to engage the aerosol generating device and the charging device for charging. In other embodiments, magnetic latching means may be used to hold the aerosol generating device engaged with the charging device. For example, magnets may be located on one or both of the rear wall and the body to engage the aerosol generating device and the charging device for charging.

[0102] A portion of the body 225 of the aerosol generating device 220 remains exposed to the external environment when engaged with the charging device 210. In some embodiments, the docking space is not enclosed, and a majority of the body 225 of the aerosol generating device 220 is exposed when the aerosol generating device 220 is engaged with the charging device 201.

[0103] Charging of the device battery may be achieved automatically upon engagement between the aerosol generating device 220 and the charging device 201. Alternatively, charging may require manual activation, for example, by operating a button.

[0104] The aerosol generating device 220 may be removed from engagement with the charging device 201 by holding the exposed portion of the aerosol generating device and moving the aerosol generating device out of the docking space with a transverse movement. In some embodiments, a mechanical latch may need to be released. In some embodiments, an extraction tool or extraction means may engage the aerosol generating device and push it out of the docking space. The extraction tool may simply be a member that pushes the aerosol generating device 220 transversely out of the docking space 205.

[0105] Once the device battery 226 is charged, the aerosol generating device can be used to consume a consumable aerosol-generating article. The aerosol generating device is disengaged from the charging device, and the aerosol-generating article is inserted into the substrate-receiving recess 221. The heater of the device 220 is activated by contacting the first contact. When the aerosol generating device is not engaged with the charging device, the first contact acts as a user-operable button and is operable with skin contact to activate the heater. The aerosol-forming substrate 231 of the article 230 is heated to a temperature sufficient to generate an inhalable aerosol. By sucking on the proximal end 235 of the article 230, the user can inhale the aerosol into their mouth and lungs. Once the article is consumed, it can be removed from the device 220, and the aerosol generating device 220 can be returned to engagement with the charging device 201 for recharging of the device battery 226.

[0106] In some embodiments, data may be transferred between the aerosol generating device and the charging device. Data may be transferred using the same contacts 217, 218, 227, 228 used for charging. Alternatively, separate data contacts may be provided. Data transfer between the charging device 201 and the aerosol generating device 220 may be performed using, for example, Bluetooth. (registered trademark) This may be accomplished wirelessly via a connection.

[0107] 3 illustrates an advantageous embodiment in which an aerosol-generating device 320 can be engaged with a charging device 301 by a plug and socket coupling. A USB plug 370 (including data and electrical contacts) extends from the rear wall of the charging device. A USB socket 371 (also including data and electrical contacts) is defined within the body 325 of the aerosol-generating device 320. A physical connection between the USB plug 370 and the USB socket 371 enables engagement between the aerosol-generating device and the charging device. The sidewalls of the aerosol-generating device 380 abut against the sidewalls of the charging device 381, leaving most of the aerosol-generating article exposed.

[0108] 4 illustrates an embodiment in which a charging device 401 defines a first docking arrangement 405 and a second docking arrangement 1405, both of which are capable of receiving an aerosol generating device 420. The system may include two or more aerosol generating devices, each of which may be as described above with respect to FIG. 3. Each docking arrangement 405, 1405 includes a USB plug 470 having electrical contacts that are electrically connected to the battery of the charging device 401. In addition to holding two aerosol generating devices 420, this embodiment allows one aerosol generating device to be used while a second aerosol generating device is being recharged.

[0109] The aerosol generating devices described above include an open cavity for receiving an aerosol-generating article. However, an aerosol generating device for use in an aerosol generating system according to the present invention may alternatively be provided with a removable mouthpiece or configured with an internal cavity for receiving an aerosol-forming substrate. The removable mouthpiece may allow access to the internal cavity for replacing the aerosol-forming substrate (e.g., a solid aerosol-forming substrate). The removable mouthpiece may be a disposable component containing the aerosol-forming substrate.

[0110] It will be understood that the above-described embodiments are merely exemplary embodiments of the invention, and that features described in connection with one embodiment may also be applied to other embodiments of the invention.
