Description

[Technical field]

[0001] The present invention relates to an electrically operated aerosol generation system, and more particularly to an electrically operated aerosol generation system having an aerosol generation device and a charging device for receiving and charging the aerosol generation 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 providing power to the atomizer. The atomizer may be an electrically operated heating means, for example an electric heater.

[0003] In some systems, the aerosol-generating device is configured to receive an aerosol-generating article that includes a solid aerosol-forming substrate, such as a substrate that includes homogenized tobacco. In these systems, the device typically includes an atomizer that is arranged to heat the aerosol-forming substrate when the article is received in the device. The article may also include a filter that is 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 that contains 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 that includes both an atomizer and a liquid aerosol-forming substrate. Such a cartridge is often referred to as a cartomizer. A common configuration of the atomizer used in a cartomizer includes a coil of heater wire wound around an elongated core that is 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 that defines a narrow opening into which a user must insert the device. The narrow opening typically has a width similar to that of the aerosol generating device. A user inserting an aerosol generating device into these cases is generally required to precisely align the aerosol generating device with the narrow opening, insert the aerosol generating device into the case, and then slide the aerosol generating device longitudinally into the case. This can be difficult for a user, especially in low light conditions or when the user is moving.

[0006] It would be desirable to provide an aerosol generating 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 with a primary power source and an elongated aerosol generating device with a secondary power source. The aerosol generating device is an elongated aerosol generating 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 generating device for charging of the secondary power source by the primary power source. A first coupling member located on the body of the aerosol generating 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 enabling 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 comprise a data contact, for example to enable data transfer between the aerosol generating device and the charging device. Thus, the first coupling member may comprise a first data contact and the second coupling member may comprise 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 opposing second end spaced from and secured relative to the first end, the docking space corresponding to a longitudinal dimension of the elongated aerosol generating device between the first end and the second end.

[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 to form 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 external 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 located 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 end and the second end.

[0014] Preferably, the first end and the second end form part of the charging device, for example forming part of a 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 an environment external to the charging device when the aerosol generating device is not housed within the docking space.

[0015] The charging device preferably comprises 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. Engagement between the charging device and the aerosol generating device when the aerosol generating device is accommodated by the docking space preferably enables 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 corresponding electrical contacts located on the charging device when the aerosol generating device is engaged with the docking arrangement.

[0016] The term "aerosol-generating device" as used herein 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 capable of forming an aerosol. In certain embodiments, an aerosol-generating article may comprise an aerosol-forming substrate capable of releasing a volatile compound capable of forming an aerosol upon heating.

[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 a downstream, proximal, or mouth end and an opposing 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 components, aerosol generating devices, aerosol generating articles, and housings.

[0021] As used herein, the term "diameter" is used to describe the maximum 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, taken 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 outside 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. The term "magnetic material" as used herein 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 in size than a second and third width dimension. While the second and third dimensions may be referred to as width and thickness, it is preferred that the second and third dimensions are substantially identical and therefore both may 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 comprise 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 simply engaged and disengaged with the docking arrangement by a movement perpendicular to the longitudinal axis of the aerosol generating device, which is a transverse movement relative to the aerosol generating device. The aerosol generating device may be simply engaged and disengaged with the docking arrangement by a movement into the docking space 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 into engagement with the charging device. The opposite end may then be pivoted into the docking space such that the aerosol generating device is fully engaged with the charging device. By using a perpendicular or substantially perpendicular movement, the distance that needs to 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 into 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 in the housing of the charging device. The docking space may therefore be at least partially defined by a first side wall, a second side wall, a rear wall, and a first end and a second end. 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 such that no portion of the aerosol generating device extends beyond the peripheral boundary of the charging device. Alternatively, the elongated aerosol generating device may only be 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 external 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 external 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 disengage the aerosol generating device from the charging device. The exposed portion of the aerosol generating device may be shaped to match or correspond 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 external 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 channel in the charging device. Thus, features of the charging device, such as displays, indicators, contacts, or buttons located in such open channels, may be shielded from the external environment when the aerosol generating device is engaged with the charging device. In this way, displays, 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 a housing of the charging device, such as 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 longitudinal dimension of the aerosol generating device, and therefore, when engaged with the charging device, the longitudinal dimension of the aerosol generating device is preferably parallel to a side or edge of the charging device.

[0032] The docking arrangement may comprise a 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 to releasably hold 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 parts that are magnetically attracted to the one or more magnets to hold the aerosol generating device engaged with the charging device when the aerosol generating device is aligned in the docking arrangement.

[0034] Latching magnets may be included on both the charging device and the aerosol generating device. A magnet on one of the charging device and the aerosol generating device may present a north pole and a corresponding magnet on the other of the charging device and the aerosol generating device may present a south pole. The aerosol generating device may include a pair of longitudinally spaced magnets and the charging device may include a corresponding pair of magnets arranged to latch with the pair of magnets on the aerosol generating device. The longitudinally spaced pair of magnets may be referred to as first and second aerosol generating device magnets and the corresponding pair of magnets may be referred to as first and second charging device magnets. The first aerosol generating device magnet may be located at or near a proximal end of the aerosol generating device. The second aerosol generating device magnet may be located at or near a distal end of the aerosol generating device. Both the first and second aerosol generating device magnets may have a north pole polarity, in which case both the first and second charging device magnets will have a south pole polarity. If the magnets of the first and second aerosol generators both have a south polarity, then the magnets of the first and second charging devices both have a north polarity. If the magnets of the first and second aerosol generators are spaced symmetrically about the longitudinal midpoint of the aerosol generator, then such an arrangement may allow the aerosol generator to latch with the charging device in either longitudinal orientation. In one arrangement, the magnet of the first aerosol generator may present a north polarity and the magnet of the second aerosol generator may present a south polarity. In this case, the magnet of the first charging device will present a south polarity and the magnet of the second charging device will present a north polarity. This configuration allows the aerosol generator to latch with the charging device when the aerosol generator is presented in a configuration in which the magnet of the first aerosol generator is aligned with the magnet of the first charging device, but no latching will occur when the aerosol generator is 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), of sufficient small size to hold the aerosol generating device and the 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 and a proximal end of the aerosol generating device may engage with a second end, with frictional engagement between the opposing ends of the device and the first and second ends of the charging device holding 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 help provide pressure between contacts located on the aerosol generating device and contacts located on the charging device to 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 a distal end or near a 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 whatever 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 whatever 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] A charging contact or a data contact defined on the body of the aerosol generating device or the charging device may serve a dual function. For example, a contact may serve as both a charging contact and as a user-operable button to activate 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 to 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 may be equipped with a means for wireless data transfer, for example a Bluetooth connection.

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

[0043] The system may also be configured such 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 indicating means (such as status lights) extending circumferentially around the aerosol generating device. Hence, the status information may be determined by a user without having to search the device for the correct aspect in which to view the status indicating means. It may be particularly advantageous for the status indicating means to be visible whatever the radial orientation in which the aerosol generating device is engaged with the charging device. Thus, the status information may be visible during charging without having to specifically orient the aerosol generating device.

[0045] A preferred status indicating means may comprise two or more longitudinally spaced lights on the aerosol generating device, each light extending circumferentially around the device. Each light may indicate the status of a different parameter. A progression of 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 comprise one or more user actuatable buttons located on a first side wall of the aerosol generating device. The aerosol generating device may comprise one or more displays located on a first side wall of the aerosol generating device. The aerosol generating device may comprise one or more contacts (such as electrical or data contacts) located on a first side wall of the aerosol generating device. The aerosol generating device may comprise any combination of user actuatable buttons, displays, and contacts (such as electrical or data contacts) located on a first side wall of the aerosol generating device. The system may advantageously be configured such that when the aerosol generating device is coupled to the charging device, the first side wall faces the charging device. For example, the docking arrangement may be configured such that when the aerosol generating device is located within the docking space, the first side wall faces the charging device. In this configuration, the aerosol generating device is radially oriented in a particular 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. An advantage of such an orientation is that buttons on the aerosol generating device may be protected from accidental actuation when the aerosol generating device is engaged with the charging device. Similarly, any display may be protected from accidental damage when the aerosol generating device is engaged with the charging device. Additionally, any contacts may be aligned with corresponding contacts on the charging device.

[0047] It is preferred that at least a portion of the aerosol generating device remains exposed when the aerosol generating device is engaged with the charging device. For example, it is preferred that at least one sidewall (e.g., at least one exterior sidewall) of the aerosol generating device remains exposed to the external environment when the aerosol generating device is engaged with the charging device. To facilitate 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 exterior sidewall. A user may be able to grip the exposed surface and apply pressure to disengage the aerosol generating device from the charging device. The aerosol generating device may thus be easier to remove from engagement with the charging device. It is preferred that at least one exterior sidewall does not have any user-actuable buttons, displays, or contacts located thereon. When the transverse cross-section of the aerosol generating device approximates a circle, the at least one exterior sidewall may include 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. At least 4 mm of the diameter of the aerosol generating device may remain exposed when the aerosol generating device is engaged with the charging device. 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 or 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 away wall portions may facilitate engagement and disengagement 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 away 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 comprise a mouthpiece at its proximal end. The mouthpiece may thus directly engage either the first end or the second end of the docking arrangement. The mouthpiece may comprise the proximal end of the aerosol generating device and a portion of the body of the aerosol generating device extending towards the distal end of the aerosol generating device. The mouthpiece preferably comprises a channel for the passage of the aerosol generated by the aerosol generating device, for example a channel having an opening defined at the proximal end of the aerosol generating device such that the aerosol can be drawn into the mouth of a user 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 or recess or a 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 or recess or a 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, the 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 such 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 locate or contain part 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 or interference fit).

[0054] The replaceable substrate section may comprise a reservoir of 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 solid aerosol-forming substrate, or a reservoir of colloidal aerosol-forming substrate, such as a gel substrate.

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

[0056] The replaceable substrate section may comprise 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 a cartomizer and may include both an aerosol-forming substrate and an atomizing component. In such an embodiment, 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, hi another embodiment, the atomizer may be an inductive susceptor that has the ability to heat when in a varying magnetic field generated by an induction coil.

[0058] In other preferred embodiments, 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 replaceable substrate sections containing two or more components which when combined form an aerosol.

[0059] The consumable aerosol-generating article may comprise 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 a cartomizer and 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 inductive 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 the mouth of a user for consumption of the article. The mouth end preferably comprises a filter that mimics a conventional conditioned 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. Hence, 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 comprise a heating element for heating the consumable aerosol generating article. The heating element may be an internal heater designed for insertion into the consumable aerosol generating article, for example a resistive 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 an external surface of the consumable aerosol generating article, for example a resistive 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 capability of holding or charging two or more aerosol generating devices simultaneously. 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0089] 1 shows a schematic diagram of a known electrically powered 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 comprises a housing 2 having the general size and shape of a conventional packet of cigarettes. A lithium ion battery 3 and electrical circuitry 4 are contained within the charging device 1. The charging device 1 further comprises 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 a 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 cavity 5, and the diameter of the device 20 is slightly smaller than the diameter of the cavity 5 so that the device 20 fits closely within the cavity 5. The aerosol generating device 20 comprises an open cavity 21 at a proximal end for receiving an aerosol-generating article. The aerosol generating device 20 further comprises a battery (not shown) contained in the housing of the device, and an electric heater (not shown) disposed within the cavity 21 for heating at least a portion of the aerosol-generating article 30 when the aerosol-generating article 30 is received within the cavity 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 aerosol-forming substrate in the form of a rod. 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, such 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 device 20 on to activate the electric heater. The electric heater heats the aerosol-forming substrate of article 30 such 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, article 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 article 30 into charging device 1, the longitudinal axis of device 20 must be precisely 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 comprises 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. The battery 203 may be referred to as the primary power source or primary battery of the system. The primary battery 203 is electrically connected to a charging port 213, allowing the primary battery 203 to be recharged with an external power source (such as a mains power source). The charging device further comprises a docking arrangement comprising a docking space 205 defined between a first end 206 and an opposing 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) to form an elongated docking space 205 having 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 comprises 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 end 223 and the distal end 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 end and the distal end by the body 225. The first device contact and the second device contact are electrically connected to a device battery 226 to allow 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, for example a lithium ion battery or a lithium iron phosphate battery.

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

[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 a 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. Further components, such as aerosol cooling elements, flavor elements, and spacing elements may be located 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 the first end 206 of the docking arrangement, and with the distal end 224 of the aerosol generating device 220 adjacent 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 of the aerosol generating device 224 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 engagement or a frictional engagement. Alternatively, a mechanical latching means may be operated automatically or manually to hold the aerosol generating device in engagement 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, a magnetic latching means may be used to hold the aerosol generating device in engagement with the charging device. For example, a magnet 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 most 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 accomplished 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 an 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 for consumption of a consumable aerosol generating article. The aerosol generating device is removed from engagement with 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 in contact with the skin 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 accomplished wirelessly, for example by a Bluetooth connection.

[0107] 3 illustrates an advantageous embodiment in which an aerosol generating device 320 may be engaged with a charging device 301 by means of a plug and socket coupling. A USB plug 370 (including data and electrical contacts) extends from a rear wall of the charging device. A USB socket 371 (also including data and electrical contacts) is defined in 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. A side wall of the aerosol generating device 380 abuts a side wall 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 docking arrangements 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 a 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 device described above includes 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 equipped 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 that contains the aerosol-forming substrate.

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