[0002] AEROSOL-GENERATING SYSTEM WITH CHARGING DEVICE

[0003] The present invention relates to an electrically operated aerosol-generating system and 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.

[0004] Electrically operated aerosol-generating systems generally comprise an aerosol-forming substrate and an atomiser, which is operated to atomise volatile compounds in the aerosol -forming substrate to form an aerosol for inhalation by a user. Typically, electrically operated aerosol-generating systems also comprise an aerosol-generating device comprising an electrical power supply for supplying power to the atomiser. The atomiser may be an electrically operated heating means, for example an electric heater.

[0005] In some systems, an aerosol-generating device is configured to receive an aerosol-generating article comprising a solid aerosol-forming substrate, for example a substrate comprising homogenised tobacco. In these systems, the device typically comprises the atomiser, which is arranged to heat the aerosol-forming substrate when the article is received in the device. The article may also comprise a filter, which is wrapped together with the aerosol-forming substrate in the form of a rod, similar to a conventional cigarette. Such systems typically employ a heating arrangement that is external to the aerosol-generating article, or use a heating arrangement located within an interior of the aerosolforming substrate.

[0006] Some electrically operated aerosol-generating systems comprise a charging device that is separate to the aerosol-generating device. Charging devices known in the art are capable of releasably holding and recharging the aerosol-generating device when the aerosol-generating device is not in use. Such charging devices may also function as a case or holder and may provide a degree of protection for the aerosol-generating device. A charging device may also provide additional functions such as data-logging and refilling of the aerosol-generating device with aerosol-forming substrate.

[0007] Aerosol-generating devices typically comprise a substrate receiving cavity to receive aerosolforming articles. Typically, when an aerosol-forming device is engaged with a charging device, the substrate receiving cavity is always covered. When the substrate receiving cavity is covered, ingress of dust and other materials, which negatively affect performance of the device, is reduced. However, this configuration means that the user cannot use the aerosol-generating device when it is engaged with the charging device.

[0008] It would be desirable to provide a system that protects the substrate receiving cavity whilst also being capable of allowing a user to generate an aerosol when the aerosol-generating device is engaged with the charging device. It would also be desirable to provide a system that allows a user to easily grasp the aerosol-generating device when it is engaged with the charging device.

[0009] According to the present disclosure, there is provided an aerosol-generating system. The aerosol-generating system may comprise an aerosol-generating device. The aerosol-generating device may comprise an elongate body extending between a proximal end and a distal end along a longitudinal dimension. The aerosol-generating device may comprise a substrate receiving cavity. The substrate receiving cavity may have an open end. The substrate receiving cavity may receive an aerosol-forming article through the open end. The aerosol-generating system may comprise a docking arrangement. The docking arrangement may be configured to engage with the longitudinal dimension of the aerosol-generating device to allow for a supply of power from the charging device to the aerosolgenerating device. The aerosol-generating system may comprise a first docked configuration. In the first docked configuration of the aerosol-generating system, the open end of the substrate receiving cavity may be at least partially covered by the charging device. In the first docked configuration of the aerosol-generating system, at least a portion of an external surface of the elongate body may be exposed. The aerosol-generating system may comprise a second docked configuration. In the second docked configuration, the open end of the substrate receiving cavity may be exposed. In the second docked configuration, at least a portion of the external body may be exposed.

[0010] In a first aspect of the disclosure there is provided an aerosol-generating system comprising, an aerosol-generating device comprising an elongate body extending between a proximal end and a distal end along a longitudinal dimension, and a substrate receiving cavity having an open end, the substrate receiving cavity for receiving an aerosol-forming article through the open end; a charging device comprising a docking arrangement configured to engage with the longitudinal dimension of the aerosol-generating device to allow for a supply of power from the charging device to the aerosolgenerating device, wherein in a first docked configuration of the aerosol-generating system the open end of the substrate receiving cavity is at least partially covered by the charging device and at least a portion of an external surface of the elongate body is exposed, and wherein in a second docked configuration of the aerosol-generating system, the open end of the substrate receiving cavity is exposed and at least a portion of an external surface of the elongate body is exposed.

[0011] Advantageously, ingress of dust and other materials into the aerosol-generating device is mitigated in the first docked configuration. Advantageously, a user can decide on whether the system is in the first or second docked configuration. For example, if the user wants to use the aerosolgenerating device they will configure the aerosol-generating system in the second configuration. Alternatively, they may want to store the aerosol-generating system. In which case they will configure the aerosol-generating system so that it is in the first configuration.

[0012] Advantageously, an aerosol-generating article can be inserted into the aerosol-generating system when it is configured as a single unit. For example, an aerosol-generating article can be inserted into the substrate receiving cavity of the aerosol-generating device while the aerosolgenerating system is in the second docked configuration where the open end of the substrate receiving cavity is exposed.

[0013] Advantageously, part of the external surface of the aerosol-generating device can be easily grasped by the user. For example, when the aerosol-generating device is engaged with the charging device, a portion of the external surface of the elongate body is exposed. The exposed external surface can be directly grasped by the user.

[0014] The docking arrangement may have an opening that is able to accommodate the longitudinal dimension of the elongate body. Foran elongate aerosol-generating device, the longitudinal dimension is greater than a transverse dimension. So, there is a larger opening in the docking arrangement through which the user can engage with the aerosol-generating device compared with an opening that only accommodates the transverse dimensions of the aerosol-generating device.

[0015] As used herein, the term “docked configuration” is used to describe a configuration when the aerosol-generating device is engaged with the docking arrangement.

[0016] As used herein, the term “exposed” is used to describe something that can be accessed by a user from the outside.

[0017] The external surface of the aerosol-generating device may comprise a docking surface. The docking surface may not be exposed when the aerosol-generating device is engaged with the docking arrangement. At least a portion of the docking surface may be configured to contact at least a portion of the docking arrangement when the aerosol-generating system is in the docked configuration.

[0018] The aerosol-generating device may be urged into the docking arrangement in a direction substantially perpendicular to the longitudinal dimension. By using substantially perpendicular movement, less distance needs to be travelled to engage the aerosol-generating device and the charging device than would be the case in a typical system in which the aerosol-generating device is inserted into a charging device in a longitudinal direction. For example, either a proximal end or a distal end of the aerosol-generating device may initially be inserted into engagement with the charging device in the docking arrangement. The opposite end may then be pivoted into the docking arrangement such that the aerosol-generating device is fully engaged with the charging device. In another example, both the proximal end and distal end may be urged towards the docking arrangement together, in a parallel motion.

[0019] In the second docked configuration, an aerosol-generating article may be inserted into the substrate receiving cavity. Advantageously, the user can puff on the aerosol-generating article while the aerosol-generating system in the aerosol-generating system is in the second docked configuration. For example, in the second docked configuration, the substrate receiving cavity is exposed, the user is able to insert an aerosol-generating article into the substrate receiving cavity and operate the aerosol-generating system to generate aerosol. The substrate receiving cavity may be located at the proximal end of the aerosol-generating device. The substrate receiving cavity may be located at the distal end of the aerosol-generating device.

[0020] The charging device may comprise a primary power source. The aerosol-generating device may comprise a secondary power source. The aerosol-generating system may further comprise electrical circuitry configured to control a supply of power from the primary power source to the secondary power source in the docked configuration. Preferably, the primary power source has a larger electrical capacity than the secondary power source.

[0021] The aerosol-generating device may be configured to generate aerosol in the docked configuration of the aerosol-generating system. The electrical circuitry may be configured to control the supply of power from the secondary power source to the heater for heating an aerosol-forming substrate when the aerosol-generating system is in the docked configuration. The electrical circuitry may be configured to control the supply of power from the primary power source to the heater for heating an aerosol-forming substrate when the aerosol-generating system is in the docked configuration. Advantageously, a user may therefore be able to generate aerosol using the aerosol- generating device without having to remove the aerosol-generating device from the charging device. The aerosol-generating system may be operable to generate aerosol in the second docked configuration when the aerosol-generating device is low on power.

[0022] The aerosol-generating device may comprise an interface. The aerosol-generating device may comprise an interface which is located on an external surface that remains exposed when the aerosolgenerating system is in the docked configuration. Advantageously, the user can interact with the interface while the aerosol-generating device is engaged with the docking arrangement. For example, when the aerosol-generating device is engaged with the docking arrangement, the interface is exposed, so the user can interact with the interface.

[0023] The charging device may comprise a docking cavity. The docking cavity may be shaped to correspond to the external shape of the aerosol-generating device. The docking cavity may be shaped to approximate at least a portion of the external surface of the aerosol-generating device. The docking cavity may form part of the docking arrangement. The docking cavity may be configured to releasably retain the aerosol-generating device.

[0024] The docking cavity may comprise an inner surface. The inner surface may be shaped to correspond to at least a portion of the external surface of the aerosol-generating device. Advantageously, the aerosol-generating device can be easily received in the docking cavity. The inner surface may be shaped to correspond to at least a portion of the docking surface.

[0025] The inner surface of the docking cavity may be defined by at least a rear wall, a first side wall and a second side wall of the charging device, the second side wall spaced from and fixed relative to the first side wall.

[0026] The docking cavity may be defined between a first longitudinal end and a second longitudinal end of the charging device. The distance between the first longitudinal end and the second longitudinal end may be substantially identical to the distance between the proximal end and the distal end. The distance between the first longitudinal end and the second longitudinal end may be different to the distance between the proximal end and the distal end.

[0027] The longitudinal length of the docking cavity may be substantially equal to the longitudinal length of the aerosol-generating device. Advantageously, there is a substantially seamless connection between the contacting surfaces of the aerosol-generating device and the charging device so that system in the docked configuration has a substantially continuous outer surface. This is beneficial, because the likelihood of accidental disengagement is reduced.

[0028] The inner surface may comprise a single continuous surface formed by the rear wall, the first side wall and the second side wall. For example, the inner surface could be shaped in a u-shape or a semi-circular shape.

[0029] The aerosol-generating system may be configured in an undocked configuration. In the undocked configuration, the aerosol-generating device is disengaged from the docking arrangement. In the undocked configuration, at least a portion of the aerosol-generating device is disengaged from the rear wall. In an undocked configuration, the aerosol-generating device may be held separately to the charging device. Transition of the aerosol-generating system from the docked configuration to an undocked configuration may be effected by movement of either the proximal end or distal end of the aerosol - generating device perpendicular to the longitudinal dimension. Preferably, transition of the aerosolgenerating system from the docked configuration to the undocked configuration occurs by the user grasping a portion of an exposed surface of the aerosol-generating device and urging the aerosolgenerating device away from the charging device in a direction substantially perpendicular to the longitudinal dimension.

[0030] The charging device may comprise the electrical circuitry. The charging device may comprise at least one primary charging contact and the aerosol-generating device may comprise at least one secondary charging contact. Each primary charging contact may be configured to contact a corresponding secondary charging contact when the aerosol-generating system is in the docked configuration. Advantageously, power may therefore be supplied using the charging contacts from the primary power source to the secondary power source in the docked configuration. Each primary charging contact may be configured to not contact the corresponding secondary charging contact when the aerosol-generating device is disengaged from the docking arrangement. Advantageously, power may therefore be prevented from being supplied using the charging contacts from the primary power source to the secondary power source in the undocked configuration.

[0031] The at least one primary charging contact may be arranged on the inner surface of the docking cavity. The at least one primary charging contact may be arranged on the rear wall of the docking cavity. The at least one primary charging contact may be arranged symmetrically. The at least one primary changing contact may be arranged at a midpoint between the first longitudinal end and the second longitudinal end of the cavity. The at least one primary charging contact may be arranged symmetrically at a midpoint between the first end and the second end of the cavity. Advantageously, the each primary charging contact may therefore be configured to contact a corresponding secondary charging contact in different aerosol-generating device orientations.

[0032] The at least one secondary contact may be arranged on the body of the aerosol-generating device. The at least one secondary contact may be arranged symmetrically about a midpoint of the external surface between the proximal end and the distal end of the aerosol-generating device. Advantageously, each secondary charging contact may therefore be configured to contact a corresponding primary charging contact in both longitudinal configurations of the aerosol-generating device when the aerosol-generating system is in the docked configuration. The secondary charging contacts may be located on the docking surface.

[0033] The charging device may comprise a plurality of primary charging contacts. The aerosolgenerating device may comprise a plurality of secondary charging contacts. The charging device may comprise a plurality of primary charging contacts and the aerosol-generating device may comprise a plurality of secondary charging contacts. For example, the charging device may comprise four primary charging contacts and the aerosol-generating device may comprise four secondary charging contacts. The plurality of primary charging contacts and the plurality of secondary charging contacts may be each arranged in a square formation. The plurality of primary charging contacts and the plurality of secondary charging contacts may be each arranged in a straight line. The plurality of primary charging contacts and the plurality of secondary charging contacts may comprise a plurality of concentric rings. The charging device may comprise three primary charging contacts and the aerosol-generating device may comprise three secondary charging contacts.

[0034] The at least one primary contacts and the at least one secondary charging contacts may be magnetic. Advantageously, the charging contacts aid in engagement of the aerosol-generating device with the docking arrangement. Preferably, magnets in the at least one primary contact and the at least one secondary contact are attracted to one another. For example, a magnet on one of the at least one primary charging contact and the at least one secondary charging contact presents a north pole and the corresponding magnet on the other of the at least one primary charging contact and the at least one secondary charging contact presents a south pole.

[0035] The charging device may comprise a movable cover. In the first configuration the cover may at least partially cover the open end of the substrate receiving cavity. The cover may not cover the open end of the substrate receiving cavity in the second docked configuration and may at least partially cover the open end of the substrate receiving cavity in the first configuration. Advantageously, the moveable cover provides a user with an option to expose the substrate receiving cavity or at least partially cover the substrate receiving cavity when the system is in a docked arrangement.

[0036] The moveable cover may be moveable in a direction parallel to the direction in which the aerosol-generating device is urged into the docking arrangement. The movable cover may comprise a sliding mechanism. Advantageously, a user can hold the aerosol-generating system in the docked arrangement and slide the moveable cover with a single hand. For example, the user can hold the aerosol-generating system and slide the cover with their thumb.

[0037] The moveable cover may comprise a hinge mechanism. The moveable cover may comprise a spring mechanism.

[0038] The moveable cover may substantially cover the open end of the substrate receiving cavity in the first docked configuration. Advantageously, ingress of dust and other materials into the substrate receiving cavity, through the open end, is limited.

[0039] The moveable cover may comprise a holding mechanism. The holding mechanism may be configured to hold the moveable cover in place in the first docked configuration. Advantageously, the moveable cover is prevented from accidentally uncovering the substrate receiving cavity. The holding mechanism may be a snap-fit mechanism. The holding mechanism may be a magnetic mechanism. The holding mechanism may be a clip mechanism.

[0040] The proximal end and the distal end of the aerosol-generating device may be exposed in the second docked configuration. Advantageously, the open end of the substrate receiving cavity is exposed, thus giving the user the option to insert an aerosol-generating article. Advantageously, the user can grasp the aerosol-generating device at either end of the aerosol-generating device when they are disengaging the aerosol-generating device from the docking arrangement.

[0041] The aerosol-generating system may further comprise a housing cover. The housing cover may be connectable to the charging device. The housing cover may be configured to substantially cover the exposed external surface of the aerosol-generating device when the aerosol-generating device is engaged with the docking arrangement. Advantageously, the aerosol-generating device is less likely to be disengaged from the docking arrangement accidentally. For example, without a housing cover, when the aerosol-generating system is in a user’s pocket, the aerosol-generating system may be accidentally contacted in a way that disengages the aerosol-generating-device from the docking arrangement. The housing cover may be connectable to the moveable cover. The housing may be configured to protect the interface when the aerosol-generating system is in the docked configuration.

[0042] The aerosol-generating system may be configured such that the proximal end or the distal end of the aerosol-generating device is exposed in the docked configuration. The aerosol-generating system is configured such that in the first docked configuration one of the proximal end or the distal end of the aerosol-generating device is at least partially exposed and in the second docked configuration the other of the proximal end or the distal end of the aerosol-generating device is at least partially exposed. Preferably, the in the first docked configuration the open end is covered and in the second docked configuration the open end is at least partially exposed. Advantageously, the user can choose whether they want to cover or expose the open end of the substrate receiving cavity.

[0043] Part of the second longitudinal end of the charging device may be a second end wall of the cavity. The second end wall may be configured to at least partially cover the proximal end or distal end of the aerosol-generating device when it is engaged with the docking arrangement. Preferably, the second end wall at least partially covers the open end in the first docked configuration. Advantageously, the second end wall, which forms part of the charging device, is capable of at least partially covering the open end without the need for an additional closing mechanism. For example, when the user engages the aerosol-generating device with the docking arrangement in the first docked configuration, no additional steps are required to cover the open end because the open end is covered by the second end wall.

[0044] In the first docked configuration the aerosol-generating device may be in a first orientation and in the second docked configuration the aerosol-generating device may be in a second orientation different to the first orientation. Advantageously, the user can easily pick which docked configuration they desire simply by orienting the aerosol-generating device. For example, the first and second orientations may be 180 degrees different to one another.

[0045] The first side wall and the second side wall may partially cover opposing sides of the aerosolgenerating device such that each opposing side is partially exposed when the aerosol-generating device is engaged with the docking arrangement.

[0046] The first side wall and the second side wall may comprise angled edges such that opposing sides of the aerosol-generating device are partially exposed when the device is engaged with the docking arrangement. Advantageously, disengagement of the aerosol-generating device is facilitated by the angled edges. For example, when the system is in the docked configuration, opposing sides of the aerosol-generating device are exposed, the exposed opposing sides can be grasped by the user.

[0047] Advantageously, the aerosol-generating device may be secured in the docking arrangement. The aerosol-generating system may be configured such that the aerosol-generating device is snap-fit in the docking arrangement. The aerosol-generating system may comprise a latching means to releasably retain the aerosol-generating device in the docking arrangement. The latching means may be a mechanical latching means. The mechanical latching means may comprise a latching projection extending from the charging device to engage with the body of the aerosol-generating device.

[0048] The latching means may be a magnetic latching means. The latching means may be positioned in the docking cavity. The latching means may be positioned in or on the rear wall. The latching means may be positioned in or on the side walls. The latching means may be positioned in or on the rear wall and the side walls. Advantageously, the magnetic latching means may provide a retaining force between the aerosol-generating device and the docking arrangement.

[0049] The magnetic latching means may comprise the at least one primary charging contact or the at least one secondary charging contact, or both the at least one primary charging contact and the at least one secondary charging contact. Advantageously, the aerosol-generating system may therefore not need additional latching components.

[0050] The magnetic latching means may comprise the at least one primary charging contact and the at least one secondary contact. The magnetic latching means may be comprised within the at least one primary charging contact and the at least one secondary charging contact.

[0051] The elongate body of the aerosol-generating device may comprises a substantially circular, elliptical, triangular, square, rhomboidal, trapezoidal, pentagonal, hexagonal or octagonal crosssection transverse to the longitudinal dimension. The docking cavity may comprise a corresponding cavity shape, to ensure a secure fit of the aerosol-generating device in the docking cavity in the docked configuration.

[0052] The elongate body of the aerosol-generating device, or the charging device, or the elongate body of the aerosol-generating device and the charging device may comprise a transparent material, such as a transparent plastic. Advantageously, a user may therefore be able to view the internal components of the aerosol-generating device or the charging device. The housing cover may comprise a transparent material.

[0053] The aerosol-generating device may comprise an atomizer configured to heat an aerosol-forming substrate. The aerosol-generating device may comprise an atomizer configured to heat a solid aerosol-forming substrate.

[0055] Preferably, the aerosol-forming substrate comprises nicotine. More preferably, the aerosol-forming substrate comprises tobacco. Alternatively or in addition, the aerosol-forming substrate may comprise a non-tobacco containing aerosol-forming material.

[0056] The solid aerosol-forming substrate may comprise, for example, one or more of: powder, granules, pellets, shreds, strands, strips, or sheets containing one or more of: herb leaf, tobacco leaf, tobacco ribs, expanded tobacco and homogenised tobacco.

[0057] Optionally, the solid aerosol-forming substrate may contain tobacco or non-tobacco volatile flavour compounds, which are released upon heating of the solid aerosol-forming substrate. The solid aerosolforming substrate may also contain one or more capsules that, for example, include additional tobacco volatile flavour compounds or non-tobacco volatile flavour compounds and such capsules may melt during heating of the solid aerosol-forming substrate.

[0058] Optionally, the solid aerosol-forming substrate may be provided on or embedded in a thermally stable carrier. The carrier may take the form of powder, granules, pellets, shreds, strands, strips, or sheets. The solid aerosol-forming substrate may be deposited on the surface of the carrier in the form of, for example, a sheet, foam, gel, or slurry.

[0119] Figure 1 shows cross-section of an aerosol-generating system 10 according to a first embodiment, the aerosol-generating system 10 comprising a charging device 1000 according to a first embodiment and an aerosol-generating device 100 according to a first embodiment.

[0120] The aerosol-generating device 100 is comprises an elongate body 110 which is substantially cuboidal and has the general dimensions of a conventional cigar. The elongate body 110 extends along a longitudinal dimension between a proximal end 114 and a distal end 116. The elongate body comprises an external surface 124. The external surface 124 comprises a docking surface 118 configured to contact the docking arrangement 1012 when the aerosol-generating system 1000 is in a docked configuration.

[0121] The aerosol-generating system 10 in Figure 1 is in an undocked configuration. In the undocked configuration, the aerosol-generating device 100 is not engaged with the docking arrangement 1012 of the charging device 1000.

[0122] The aerosol-generating device 100 comprises a substrate receiving cavity 160 at a proximal end 114 for receiving an aerosol-generating article (not shown). The aerosol-generating device 100 further comprises an electric heater (not shown), such as a resistive heater arranged to surround the cavity 160 for heating at least a portion of an aerosol-forming the aerosol-generating article when the aerosolgenerating article is received in the substrate receiving cavity 160. In other embodiments, the electric heater may be in the form of a blade or pin that extends at least partially through the substrate receiving cavity in the longitudinal dimension. A suitable aerosol-generating article may for example include an aerosol-forming substrate comprising a gathered, crimped sheet of tobacco, and a filter arranged back to back with the aerosol-forming substrate in the form of a rod. The aerosol-generating article would have a diameter substantially equal to the diameter of the cavity 160 of the device and a length longer than the substrate receiving cavity 160, such that when the article is received in the cavity 160 of the device, the filter extends out of the substrate receiving cavity 160 and may be drawn on by a user, similarly to a conventional cigarette.

[0123] The aerosol-generating device 100 further comprises a power source 190, herein referred to as a secondary power source 190, housed in the elongate body 110 of the device. The secondary power source 190 is a rechargeable battery, such as a lithium-ion battery. The aerosol-generating device 100 further comprises control circuitry 180 configured to control the supply of power from the secondary power source 190 to the electric heater.

[0124] The aerosol-generating device 100 further comprises secondary electrical contacts 170 located on the docking surface 118. The secondary electrical contacts 170 are arranged symmetrically about a midpoint of the aerosol-generating device 100 between the proximal end 114 and the distal end 116. The secondary electrical contacts 170 are electrically connected to the secondary power source 190 and the control circuitry 180.

[0125] The charging device 1000 comprises a docking arrangement 1012. The docking arrangement 1012 is configured to receive the aerosol-generating device 100 when the aerosol-generating device 100 is urged into the docking arrangement 1012 in a direction substantially perpendicular to the longitudinal dimension. The docking arrangement 1012 comprises a docking cavity 1020. The docking cavity 1020 extends between a first longitudinal end 1014 and a second longitudinal end 1016 in a longitudinal dimension. The docking cavity 1020 is substantially identical in length to the aerosolgenerating device 100 in the longitudinal dimension.

[0126] The docking cavity 1020 is partially defined by a rear wall 1018. The docking cavity 1020 is further partially defined by two opposing side walls, and is open at a front side 1024 to receive therethrough the aerosol-generating device 100. The rear wall 1018, and two opposing side walls form an inner surface of the docking cavity 1020. The inner surface is a surface with a dimensions that correspond with dimensions of the aerosol-generating device 100.

[0127] In the embodiment illustrated in Figure 1 , the docking cavity 1020 is open at the first longitudinal end 1014, and closed by a second end wall 1017 at the second longitudinal end 1016. The docking arrangement 1012 is capable of receiving the aerosol-generating device in two orientations. That is, in a first docked configuration and a second docked configuration. These configurations will be described in greater detail in the description of Figures 3a and 3b.

[0128] The charging device 1000 further comprises primary electrical contacts 1070 located on the rear wall 1018 of the charging device 1000. The primary electrical contacts 1070 are arranged symmetrically about a midpoint of the rear wall 1018 between the first longitudinal end 1014 and the second longitudinal end 1016.

[0129] Although in Figure 1 the charging device 1000 and the aerosol-generating device 100 are illustrated as each comprising two charging contacts 170, 1070, the skilled person would understand that they may instead each comprise alternative numbers and arrangements of charging contacts 170, 1070. For example, the charging device 1000 and the aerosol-generating device 100 may each comprise four charging contacts arranged in a line or a square configuration. The charging device 1000 and the aerosol-generating device 100 may each comprise charging contacts arranged in a concentric circle configuration.

[0130] The charging device 1000 further comprises a primary power source 1090, herein referred to as a primary power source 1090. The primary power source 1090 is a rechargeable battery, such as a lithium-ion battery. The charging device 1000 further comprises a charging device electrical circuitry 1080. The primary electrical contacts 1070 are electrically connected to the primary power source 1090 and charging device electrical circuitry 1080. The charging device electrical circuitry 1080 is configured to control the supply of power from the primary power source 1090 to the secondary power source 190 using the primary electrical contacts 1070 and the secondary electrical contacts 170.

[0131] The primary electrical contacts 1070 and the secondary electrical contacts 170 also comprise magnetic components, such that a magnetic force is provided between the primary electrical contacts 1070 and the secondary electrical contacts 170. This magnetic force ensure retention of the aerosolgenerating device 100 in the docking arrangement 1012. It can be understood that alternative or additional latching means are also possible. For example, at least one of the elongate body of the aerosol-generating device 100 and the charging device 1000 may comprise protrusions configured to engage with the other of the aerosol-generating device 100 and the charging device 1000 to provide a force for retaining the aerosol-generating device 100 in the docking cavity 1020.

[0132] Figures 2a, 2b and 2c show side, front and top views respectively of the charging device 1000 shown in Figure 1.

[0133] As shown in Figure 2a, the side walls 1038 of the docking cavity 1020 are tapered, extending from substantially zero width at the first longitudinal end 1014 of the docking cavity 1020, to extending the full width between the rear wall 1018 and the front side 1024 at the second longitudinal end 1016 of the docking cavity 1020. In other words, the side walls 1038 of the docking cavity 1020 comprise angled cut-out portions. The side walls 1038 are configured to leave at least a portion of the external surface 124 of the aerosol-generating device 100 exposed when the aerosol-generating system 10 is in the docked configuration.

[0134] Although in Figure 1 the docking cavity 1020 and the aerosol-generating device 100 are illustrated as being substantially cuboidal in shape, the skilled person would understand that they may instead have a different shape or cross sections. For example, the inner surface of the docking cavity 1020 and the aerosol-generating device 100 may be substantially cylindrical, or may have another polygonal cross-section. In these embodiments, the rear wall 1018 and opposing side walls 1038 of the inner surface may instead form a continuous smooth curved surface.

[0135] Figure 3a shows a cross-section of the aerosol-generating system 10 in a first docked configuration.

[0136] In the docked configuration, the aerosol-generating device 100 is engaged with the docking arrangement 1012, such that the primary charging contacts 1070 are in physical and electrical contact with the secondary charging contacts 170. The docking surface 118 of the aerosol-generating device 100 contacts and is flush with the rear wall 1018.

[0137] In the docked configuration the aerosol-generating system 10 is configured such that power is supplied from the primary power source 1090 to the secondary power source 190 using the primary charging contacts 1070 and the secondary charging contacts 170. Such a supply of power is controlled by at least one of the charging device electrical circuitry 1080 and the control circuitry 180 within the aerosol-generating device 100.

[0138] In the first docked configuration illustrated by Figure 3a, the proximal end 114 of the aerosolgenerating device 100 is located at the second longitudinal end 1016 of the docking cavity 1020. The open end of the substrate receiving cavity 160 of the aerosol-generating device 100 is covered, as the proximal end 114 of the aerosol-generating device 100 is covered by the second end wall 1017 at the second longitudinal end 1016 of the docking cavity 1020. In the first docked configuration, the substrate receiving cavity 160 cannot receive an aerosol-forming article. The aerosol-generating device 100 is therefore prevented from generating aerosol whilst in the first docked configuration as illustrated in Figure 3a. In other embodiments, the open end of the substrate receiving cavity is only partially covered by the second end.

[0139] Figure 3b shows a cross-section of the aerosol-generating system 10 of Figure 1 in a second docked configuration. The second docked configuration differs from the first docked configuration in that the aerosol-generating device 100 is engaged with the docking arrangement 1012 in a different orientation. In the second docked configuration, the proximal end 114 of the aerosol-generating device 100 is located at the first longitudinal end 1014 of the docking cavity 1020. The open end of the substrate receiving cavity 160 is therefore exposed, as the proximal end 114 of the aerosol-generating device 100 is not covered. In the second docked configuration the exposed substrate receiving cavity 160 can receive an aerosol-forming article. The aerosol-generating device 100 may therefore be used to generate aerosol whilst in the second docked configuration.

[0140] Figure 3c shows a cross-section of the aerosol-generating system 10 of Figure 1 in a second docked configuration with an aerosol-forming article 165 inserted in the substrate receiving cavity 160. In the second docked configuration, the open end of the substrate receiving cavity 160 exposed. An aerosol-forming article 165 is inserted into the substrate receiving cavity 160 while the aerosolgenerating device 100 is in the second docked configuration.

[0141] The aerosol-forming article 165 comprises a filter (not shown), which is wrapped together with the aerosol-forming substrate in the form of a rod, similar to a conventional cigarette. The user puffs on the filter to draw aerosol out of the aerosol-forming article.

[0142] The aerosol-generating system 10 can be configured to generate aerosol in the second docked configuration by heating the aerosol forming substrate in the aerosol-forming article 265 when it is inserted into the substrate receiving cavity 160. The electrical circuitry 180 is configured to control supply of power from the secondary power source 190 to the heater (not shown) for heating the aerosol-forming substrate. When the secondary power source 190 has limited available power, the charging device electrical circuitry 1080 can be configured to control the supply of power from the primary power source 1090 to the heater for heating an aerosol-forming substrate when the aerosolgenerating system 10 is in the second docked configuration.

[0143] Figure 4 shows a cross-section of an aerosol-generating system 20 according to a second embodiment. The aerosol-generating device 200 in the second embodiment is substantially identical to the aerosol-generating device 100 in the first embodiment. The charging device 2000 in the second embodiment is similar to the charging device 1000 in the first embodiment shown in Figure 1. So, the differences between the aerosol-generating system 20 of the second embodiment will be described with respect to differences only.

[0144] The charging device 2000 comprises a docking arrangement 2012. The docking arrangement 2012 comprises a docking cavity 2020 which is open at both the first longitudinal end 2014 and the second longitudinal end 2016. In other words, the docking cavity 2020 is defined between the two opposing side walls and the rear wall 2018.

[0145] There may be embodiments where the aerosol-generating device 200 comprises a holding means to hold the movable cover in place when the aerosol-generating system 20 is in a docked configuration. In further embodiments, the holding means may instead located on the charging device 2000. The charging device 2000 further comprises a moveable cover 2050. The moveable closing means 2050 comprises a sliding mechanism. The movable cover 2050 is configured to slide in a direction perpendicular to the longitudinal dimension of the charging device 2000. In other embodiments, the movable cover may comprise a hinge mechanism, to rotate about a point or axis.

[0146] Figures 5a, 5b, and 5c show side, front and top views respectively of the charging device 2000 shown in Figure 4. As shown in Figure 5a, the side walls 2038 of the docking cavity 2020 are extending the full width between the rear wall 2018 and the front side 2024 for the entire longitudinal length of the docking cavity 2012 between the first longitudinal end 2016 and the second longitudinal end 2014 of the docking cavity 2012. When the aerosol-generating system 20 is in the docked configuration the side walls 2038 extend a portion of the width of the aerosol-generating device 200.

[0147] Figure 6a shows a cross-section of the aerosol-generating 20 system of Figure 4 in a second docked configuration.

[0148] In the docked configuration, the aerosol-generating device 200 is engaged with the docking arrangement 2012, such that the primary charging contacts 2070 are in physical and electrical contact with the secondary charging contacts 270. The docking surface 218 of the aerosol-generating device 200 contacts and is flush with the rear wall 2018.

[0149] In the docked configuration the aerosol-generating system 20 is configured such that power is supplied from the primary power source 2090 to the secondary power source 290 using the primary charging contacts 2070 and the secondary charging contacts 270. Such a supply of power is controlled by at least one of the charging device electrical circuitry 2080 and the control circuitry 280 within the aerosol-generating device 200.

[0150] In the docked configuration, the proximal end 214 of the aerosol-generating device 200 is located at the first longitudinal end 2014 of the docking cavity 2020.

[0151] In the second docked configuration, the moveable cover 2050 is in an open position. In the open position, the moveable cover 2050 is in a position that does not cover the open end of the substrate receiving cavity 260.

[0152] The open end of the substrate receiving cavity 260 is therefore exposed, as the proximal end 214 of the aerosol-generating device 200 is not covered. In the second docked configuration the exposed substrate receiving cavity 260 can receive an aerosol-forming article. The aerosol-generating device 200 may therefore be used to generate aerosol whilst in the second docked configuration.

[0153] When engaged with the charging device 200 in the second docked configuration, the proximal end 214 of the aerosol-generating device 200 is located at either the first longitudinal end 2014 or the second longitudinal end 2016 of the docking cavity 2012. Because the docking cavity 2020 is open at both the first longitudinal end 2014 and the second longitudinal end 2016, the substrate receiving cavity 260 of the aerosol-generating device 200 is therefore exposed in either longitudinal orientation of the aerosol-generating device 200. The aerosol-generating device 200 may therefore be used to generate aerosol whilst in two orientations.

[0154] Figure 6b shows a cross-section of the aerosol-generating system 20 of Figure 4 in a first docked configuration. In the first docked configuration, the moveable cover 2050 is in a covering position. In the covering position, the moveable cover 2050 is in a position that covers the open end of the substrate receiving cavity 260. In other embodiments, the moveable closing means 2050 partially covers the open end of the substrate receiving cavity 260.

[0155] In the first docked configuration, the substrate receiving cavity 260 cannot receive an aerosolforming article. The aerosol-generating device 200 is therefore prevented from generating aerosol whilst in the first docked configuration as illustrated in Figure 6b.

[0156] Figure 6c shows a cross-section of the aerosol-generating system 20 of Figure 4 in a second docked configuration with an aerosol-forming article 265 inserted in the substrate receiving cavity 260. In the second docked configuration, the cover 2050 is in an open position, leaving the open end of the substrate receiving cavity 260 uncovered. An aerosol-forming article 265 is inserted into the substrate receiving cavity 260 while the aerosol-generating device 200 is in the second docked configuration.

[0157] The aerosol-forming article 265 also comprises a filter (not shown), which is wrapped together with the aerosol-forming substrate in the form of a rod, similar to a conventional cigarette.

[0158] The aerosol-generating system 20 is configured to generate aerosol in the second docked configuration by heating the aerosol forming substrate in the aerosol-forming article 265 when it is inserted into the substrate receiving cavity 260. The electrical circuitry 280 is configured to control supply of power from the secondary power source 290 to the heater (not shown) for heating the aerosol-forming substrate. When the secondary power source 290 has limited available power, the charging device electrical circuitry 2080 can be configured to control the supply of power from the primary power source 2090 to the heater for heating an aerosol-forming substrate when the aerosolgenerating system 20 is in the second docked configuration.
