    [0001] [001] The present invention relates to an aerosol generating device, which is adapted to resist rolling. The invention also relates to a system comprising the aerosol generating device and a charging device for receiving the aerosol generating device.
    [0002] [002] Aerosol generating articles in which an aerosol-forming substrate, such as a tobacco-containing substrate, is heated rather than burned are known in the art. The purpose of such heated aerosol generation articles is to reduce the known harmful smoke constituents produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes. Typically, in such heated aerosol generating articles, an inhalable aerosol is generated by transferring heat from a heat source to a physically separate aerosol-forming substrate or material, which can be located within, the fence. of, or downstream of the heat source. During consumption, volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and entrained by pulling air through the aerosol generating article. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    [0003] [003] A number of prior art documents describe aerosol generating devices for the consumption of heated aerosol generating articles. Such devices include, for example, heated smoking systems and electrically heated smoking systems and smoking articles containing an aerosol-forming substrate based on tobacco consumed using such systems.
    [0004] [004] It would be desirable to provide such a device, which remains stationary, while not in use, for example, an aerosol generating device that resists rolling when set down on a flat surface. US2010 / 0313901 shows such a device. A user may want to place the device on a flat surface, such as a table, and if the device is to roll, it may fall to the floor and be damaged. In addition, any aerosol generating article in the process of being consumed can become dirty and need to be replaced. It would also be desirable to provide such an aerosol generating device that is ergonomic to maintain in use.
    [0005] [005] It is also known in the art to provide a secondary device for charging the aerosol generating device, while the aerosol generating device is not in use, referred to as a charging device or secondary device here. Providing such a loading device allows the aerosol generating device to be smaller and lighter. The charging device may also provide a means for storing information regarding the use of the aerosol generating device that is discharged from the aerosol generating device when coupled with the charging device. If the connections between the connections of an aerosol generating device are incorrectly coupled to the contacts of a secondary device, such as a charging device, damage can be done to the electronics within one or both devices.
    [0006] [006] It would be desirable to provide an aerosol generating system, comprising an aerosol generating device and a secondary device for charging the aerosol generating device that reduces the possibility of incorrectly connecting the aerosol generating device to the secondary device. .
    [0007] [007] As used herein, an "aerosol generating device" refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol forming substrate may be part of an aerosol generating article, for example, part of a smoking article. An aerosol generating device can comprise one or more components used to supply energy from a power source to an aerosol-forming substrate to generate an aerosol. For example, an aerosol generating device can be a heated aerosol generating device. An aerosol generating device may be an electric heating aerosol generating device or a heated gas aerosol generating device. An aerosol generating device may be a smoking device, which interacts with an aerosol forming substrate of an aerosol generating article to produce an aerosol that is directly inhaled into a user's lungs through the user's mouth.
    [0008] [008] As used herein, the term "aerosol-forming substrate" refers to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. As an alternative to heating or combustion, in some cases, volatile compounds can be released by a chemical reaction or by a mechanical stimulus, such as ultrasound. An aerosol-forming substrate can be solid or liquid, or comprise both solid and liquid components. An aerosol-forming substrate can be adsorbed, coated, impregnated or otherwise loaded onto a vehicle or support. An aerosol forming substrate can conveniently be part of an aerosol generating article or a smoking article.
    [0009] [009] An aerosol-forming substrate may comprise nicotine. An aerosol-forming substrate may comprise tobacco, for example, it may comprise a tobacco-containing material, containing volatile tobacco flavor compounds, which are released from the aerosol-forming substrate upon heating. In preferred embodiments, an aerosol-forming substrate may include homogenized tobacco material, for example, fused tobacco leaf. An aerosol-forming substrate can comprise at least one aerosol former, such as propylene glycol or glycerin.
    [0010] [0010] As used herein, "aerosol generating article" and "smoking article" refer to an article comprising an aerosol-forming substrate that is capable of releasing volatile compounds that can form an aerosol. For example, an aerosol generating article may be a smoking article that generates an aerosol that is directly inhaled into a user's lungs through the user's mouth. An aerosol generating article may be disposable. The term aerosol generation article is generally used below.
    [0011] [0011] Preferably, an aerosol generating article is a heated aerosol generating article, which is an aerosol generating article comprising an aerosol forming substrate that is intended to be heated instead of burned in order to to release volatile compounds that can form an aerosol. The aerosol formed by heating the aerosol-forming substrate may contain less known harmful constituents than would be produced by combustion or pyrolytic degradation of the aerosol-forming substrate. An aerosol generating article may be, or may comprise, a strip of tobacco.
    [0012] [0012] In one aspect, an aerosol generating device is provided that comprises a heating element and an outer shell, in which the outer shell is elongated and adapted to resist rolling.
    [0013] [0013] The casing may, for example, comprise one or more projections or projections that fall on a surface that the device begins to roll. The projections or projections effectively stabilize the device against the bearing.
    [0014] [0014] The external shape of the box can act to stabilize the device against the bearing. For example, the casing can be elongated and have at least one longitudinal edge. An example of a shape, which has a longitudinal edge and increases stability against the bearing, could be a cylinder, which has a cross section in the shape of a teardrop.
    [0015] [0015] The outer shell has a cross section formed by a shape having at least three corners connected by curves. The presence of three corners advantageously stabilizes the device against the bearing.
    [0016] [0016] An aerosol generating device can be any aerosol generating device, as defined in the appended claims.
    [0017] [0017] An aerosol generating device may have an external cross-section defined by a shape that has at least five sides. It is preferred that the aerosol generating device has a high aspect ratio and that a substantial part of the length has a defined cross section. The total length of the device can have a defined cross section.
    [0018] [0018] The external cross section can be a polygonal cross section. The polygon comprises at least five sides. The polygon can comprise at least six sides.
    [0019] [0019] The device can be greater than 60 mm in length. The device can be less than 150 mm in length. For example, the device can be between 80 mm and 120 mm in length. The device can be between 90 mm and 110 mm in length.
    [0020] [0020] An external circumference of the shape of the cross section can have a diameter greater than 10 mm. An outer circumference of the shape of the cross section can have a diameter of less than 20 mm. An external circumference of the shape of the cross section can have a diameter between 12 mm and 16 mm. The cross section of a polygon can be defined by the line that passes from one edge of the polygon, through the center of the polygon, and an opposite edge. The length of this line can be between 10 mm and 20 mm. Preferably between 12 mm and 15 mm. A polygon on the same side can have a transverse line that passes from a flat face of the polygon to an opposite flat face of the polygon. This distance can be, for example, between 12 mm and 14 mm. A polygon on the same side can have a transverse line that passes from a corner of the polygon to an opposite corner of the polygon. This distance can be, for example, between 12 mm and 14 mm. The corner-to-corner cross section will be slightly longer than the face to face cross section.
    [0021] [0021] The sides of the shape of the cross section can all be the same length. The sides of the shape of the cross section can have different lengths. Preferably, one or more sides have a length greater than 2 mm, preferably greater than 3 mm, or greater than 4 mm. It may be advantageous for one or more sides to be longer than 5 mm. The length of one side of the shape of the cross section can be the same as the width of a facet of the three-dimensional device. For example, if the device is substantially cylindrical and has a cross section that is an equilateral hexagon with 5 mm long sides, the device will have six 5 mm longitudinal facets.
    [0022] [0022] The shape of the cross section preferably has at least five corners joined by curves so as to form the shape having at least five sides. The curves have a large radius compared to the side length of between 100mm and 10000mm, so that the side deviates slightly from the linear and gives the appearance of being almost flat.
    [0023] [0023] The aerosol generating device can be substantially cylindrical. The term cylindrical as used herein describes a three-dimensional shape that has substantially parallel sides and a base defined by a two-dimensional shape. The two-dimensional shape that is defined by the cross section, that is, a shape that has at least five sides. The term cylindrical as used herein may be equivalent to the term prismatic. By substantially parallel it means that the sides need not be exactly parallel. For example, the sides can be within about 5 degrees of true parallel.
    [0024] [0024] A part of the aerosol generating device may be in the form of an elongated pyramid trunk, which has converging sides and a base defined by a two-dimensional shape. The two-dimensional shape is that defined by the cross section, that is, a shape that has at least 5 sides.
    [0025] [0025] Preferably, each side of the two-dimensional shape that defines the cross section corresponds to an elongated face on an external surface of the device.
    [0026] [0026] By providing an aerosol generating device with such a shape in a multifaceted cross section the surface area of the device is increased compared to a device that has a circular cross section. For example, a device that is substantially cylindrical and has a cross section in the shape of a polygon, with at least five sides, advantageously provides the user with a more ergonomic feel, increasing the stability of the device when it is placed on a surface , while it is not in use. It is provided that a user may want to place the device on a flat surface, for example, a table. If the device were to roll, the user may be disturbed. A device that comprises shape features that help to stabilize the device and resist rolling will be advantageous.
    [0027] [0027] The shape of the cross section, for example, a polygon, can comprise between 6 and 16 sides, preferably between 7 and 12 sides. In a preferred embodiment, the shape is a polygon with 10 sides.
    [0028] [0028] The polygon can be a regular polygon. The term regular polygon refers to a polygon that is equi-angle, all angles are equal and equilateral, all sides are the same length. The sides are slightly curved. The angles can be formed by sharp corners or rounded corners. The aerosol generating device may have a regular polygonal cross-section along its entire length. Alternatively, the aerosol generating device may have a regular polygonal cross section that extends over only part of its length. For example, the cross section of the aerosol generating device may vary due to the presence of a button. Such a button can be adapted to activate the device in use. The position of the button can be chosen to facilitate the presentation of the button on a higher surface, regardless of the shape of the device.
    [0029] [0029] As used herein, the term "length" refers to the dimension, in the longitudinal direction. The term "longitudinal" refers to the main axis of the elongated aerosol generating device. As used herein, the term "transverse" refers to a direction perpendicular to the longitudinal direction.
    [0030] [0030] At least one end of the aerosol generating device can be tapered. Alternatively, both ends of the aerosol generating device can be tapered. Preferably, the radius of the or each face of the end of the tapered end is at least 50% of the maximum radius of the aerosol generating device. The radius of a polygon is measured from the center of gravity of a polygon at the vertex of the polygon.
    [0031] [0031] Whenever at least one end of the aerosol generating device is tapered, preferably at least one end of the aerosol generating device is tapered over at least about 5% of the length of the device. More preferably, the at least one end of the aerosol generating device is tapered over at least about 7% of the length of the device. Even more preferably, the at least one end of the aerosol generating device is tapered over at least about 7.5%.
    [0032] [0032] Whenever the at least one end of the aerosol generating device is tapered, the taper can be linear or curved. The presence of a cone can be particularly advantageous when one end of the device is configured to be inserted into and with another device. For example, one or more electrical contacts can be located at or near a first end of the device in such a way that they can be brought into contact with the electrical contacts located within a receiving cavity of another device. The tapered end of the device, together with a coupling receiving part, allows the device to be coupled quickly and easily by a user. The taper guides the device into a correct position within the receiving cavity. Due to the guiding effect provided by the taper, it is possible for a user to couple the device to another device, for example, a charging unit, without looking at the device to align the contacts. This can be advantageous as the act of attaching the device to another device can be performed in the dark or when a user is engaged in conversation.
    [0033] [0033] The user of an aerosol generating device may wish to rest the device on a surface when consuming the aerosol generating article. It may be desirable to place the device downwards, as a mouth end of the article can then come in close proximity to the surface, which can be unhygienic. It may be preferable to tilt the device such that the mouth end of the article is raised from the surface. Advantageously, the presence of a cone can facilitate the inclination of the device in contact with the surface and a stationary object elevated above the surface. The taper, in conjunction with a molded cross section, causes a large area of the surface to come into contact with the surface when the device is tilted at an appropriate angle. This can increase the stability of the device when it is tilted at an angle. The ideal tilt angle may depend on the angle of the cone. An ideal inclined angle can, for example, be between 25 degrees and 60 degrees from the surface.
    [0034] [0034] Preferably, the elongated aerosol generating device comprises an outer shell having a receiving cavity substrate adapted to receive an aerosol generating article, including an aerosol forming substrate, a heating element adapted to heat a substrate of aerosol formation to generate an aerosol, and a power source adapted to supply energy to the heating element. The device may also comprise a controller for controlling the power delivered from the power supply to the heating element.
    [0035] [0035] Whenever the aerosol generating device comprises a substrate receiving cavity, a support can be provided inside the cavity. The support is adapted to support an aerosol forming substrate, adjacent to the end of the aerosol generating device that has the cavity. The aerosol forming substrate itself is preferably a component part of an aerosol generating article that can be received on the support.
    [0036] [0036] The external shape of the device can be defined by an enclosure. The housing may form a retaining shell for component parts of the device. The housing can have an internal cross section that has the same shape as its external cross section. The housing may have an internal cross section that is circular. The housing can have an internal cross section that is non-circular and differently to the external cross section.
    [0037] [0037] When the device comprises a support adapted to hold an aerosol generating article, including an aerosol-forming substrate, a plurality of air inlets that lead to a plurality of air channels within the device can be formed by a space between the holder and the outer casing part. For example, the support can have an external circular cross section and the enclosure can have a decagonal internal cross section. If the support is mounted inside the enclosure in such a way that an external part of the support terminals of each of the ten inner faces of the inner surface of the enclosure, ten openings are defined by spaces between the corners of the decagon and the support. These gaps can act as air intakes. The air inlet area can be controlled by selecting the internal shape of the compartment, or by selecting the internal shape of the housing in the housing part, which defines the substrate receiving cavity.
    [0038] [0038] The air channels may diverge away from the air inlets inside the device, as the outer shell diverges with tapering. The provision of such air channels can improve the incorporation of air into the device. In addition, the incoming air can improve the insulation between the aerosol forming substrate and the outer shell.
    [0039] [0039] The substrate receiving cavity can be adapted to receive an aerosol generating article having a mouth end and a distal end, an aerosol forming substrate being located at the distal end. The distal end of the aerosol generating article is introduced into the substrate receiving cavity.
    [0040] [0040] In use, a user inserts an aerosol generating article into the receiving cavity of the device's substrate, activates the device, applies his lips from the end of the mouth of the aerosol generating article, and inhales. Air and any aerosol generated inside the device are attracted through the mouth end of the aerosol generating article to be inhaled by the user. When the user inhales, air and aerosol move through the aerosol generating article from the distal end to the end of the mouth. In some embodiments, air can be drawn into the device through the proximal end of the device to the aerosol generating article. In some embodiments, air can be drawn into the device through a side wall. In other embodiments, air can be drawn into the device through a combination of the proximal end of the device and a side wall of the device.
    [0041] [0041] The aerosol generating article can be substantially cylindrical in shape. The aerosol generating article can be substantially elongated. The aerosol generating article can also have a length and a circumference substantially perpendicular to the length. The aerosol generating article can be received in the cavity of the aerosol generating device in such a way that the length of the aerosol generating article is substantially parallel to the direction of the air flow in the aerosol generating device.
    [0042] [0042] Whenever the aerosol generating device has a shell, the shell may be an elongated shell having a length between 60 mm and 150 mm. The enclosure can have a wall thickness between 0.2 mm and 1 mm. If the casing is formed from a metallic material, the wall thickness is preferably between 0.2 mm and 0.4 mm. If the shell is formed from a polymer the wall thickness is preferably between 0.5 and 1 mm, for example, between 0.6 mm and 0.8 mm, or about 0.75 mm.
    [0043] [0043] The outer shell of the aerosol generating device can be manufactured from two, four or more parts. The parts are preferably joined along a cross section of the device, and can be adapted to join around one or more buttons protruding from the device. When the outer shell consists of four parts, the parts may be two tapered end parts, and two substantially cylindrical central parts. In some embodiments, a first part of the housing may define the external shape of a first end of the device, and a second part of the housing may define the external shape of a second end of the device. Two adjacent housing parts can come together at a junction located approximately halfway along the length of the device. Two parts of the housing may come together at a junction that is closer to one end of the device than the other. Preferably, the housing parts are separable, for example, a first housing part may be able to be separated from a second engaging part by sliding the separated housing parts in a longitudinal direction. Access to an internal part of the device can be obtained by removing one or more parts of the housing.
    [0044] [0044] It may be preferable for the aerosol generating device to comprise a part of the housing that is attached to the internal components of the device, and cannot be removed from the device, and a part of the additional housing that can be removed from the device. It may be preferable that one end of the device, comprising the substrate receiving cavity, can be removable from the device. Any support within the substrate receiving cavity can be removed with the housing part. Removing a part of the housing may be desirable in order to access internal component parts of the device, for example, to clean the device. The movement of a part of the wrapper, or the removal of a part of the wrapper, may also be desirable, in order to assist the removal of aerosol generating articles after using the device.
    [0045] [0045] Whenever a part of the enclosure is removable from the device, it may be desirable that the enclosure part should only be attachable to the device in a specific orientation. The part of the removable housing can, for example, slide along a substantially cylindrical internal part of the device. In such circumstances, the inner surface of the enclosure may define a notch or protrusion that keys with a corresponding protrusion or notch on the inner part to ensure that the enclosure part can only be coupled to the aerosol generating device with a specific orientation.
    [0046] [0046] Whenever a part of the enclosure is sliding in relation to the internal components of the device, it may be advantageous that the part of the enclosure can be retained in one or more stable positions. For this purpose, the inner surface of the housing part may comprise projections that engage with a defined projection on an internal part of the device to act as closures. For example, two protrusions spaced longitudinally on the inner surface can interact with a protrusion on the inside of the device to locate the housing part. Preferably, the protrusion on the inner part is protruded such that it can be made to pass the protrusions over the enclosure under the application of a force. It may be particularly advantageous that the inner surface of the enclosure has a non-circular cross-sectional shape, for example, a polygonal shape. By locating the projections in the corners of the inner surface of the enclosure, it is possible to control the fitting properties to optimize its function. A part of the removable housing may have a snap assembly that hold the housing part in a fully closed position adjacent to a second housing part. There may be a second fitting assembly that holds the housing part in a second position, which is slidably removed in the first position, but still attached to the device. The relative strength of different joint assemblies can be varied.
    [0047] [0047] Whenever an external enclosure comprises two or more separate parts, the visual aspect of the device can be impaired if the two or more parts do not line up precisely. For example, if the device is in the form of a cylinder that has a polygonal base, any incompatibility or misalignment between the adjacent housing parts will immediately become apparent when the housing parts are joined. This can be a result of light reflecting at different angles from substantially flat longitudinal faces defined on the outer surface of the housing. If the longitudinal faces are not perfectly flat, however, the visual impairment may not be as evident. For example, if the device has a polygonal cross section, and the faces of the polygon are very slightly curved outward, the longitudinal faces of the device will have a slight transverse curvature. This slight curvature produces an optical effect that can disguise imperfect alignments between adjacent parts of the enclosure, which may not be as evident as if the faces were perfectly flat. While some curvature may be desirable, it is preferable that any convex curvature is not sufficient to facilitate the rolling of the device. Thus, it is preferable that any curve outlining a face in the outer cross section of the device has a radius that is substantially greater than the distance along the face. In this way, the device can be both aesthetically pleasing, have a pleasant ergonomic feel, and have an external shape that provides stability against the bearing.
    [0048] [0048] The outer shell of the aerosol generation system can be manufactured from any suitable material or combination of materials. Examples of suitable materials include, but are not limited to, metallic and metal materials, metal alloys, polymers and plastics, or composite materials containing one or more of these materials, or thermoplastics that are suitable for food or pharmaceutical applications, for example, polypropylene, polyete retercetone (PEEK) and polyethylene. Preferred materials can include aluminum and aluminum alloys, acrylonitrile butadiene styrene (ABS), and polycarbonate (PC). When a metal, metallic material or composite material comprising a metal is used, the surface can be anodized or otherwise treated to improve the appearance of the surface and provide a scratch resistance for the device's casing. Likewise, when the material does not comprise a metal, metallic material or composite material, the materials can be selected to optimize the appearance and functionality, for example, scratch resistance, of the enclosure.
    [0049] [0049] In another aspect, an aerosol generation system is also provided. The system comprises an elongated aerosol generating device, as described above, and a loading device comprising a cavity with an opening suitable for receiving the aerosol generating device. It may be advantageous that the aerosol generating device can be inserted into the cavity in a predetermined orientation.
    [0050] [0050] Preferably, the aerosol generating device comprises a means for encoding the aerosol generating device for the receiving cavity of the loading device. The coding means may comprise at least one notch to receive at least one corresponding protrusion in the aerosol generating device. The at least one projection can be a button adapted to activate the aerosol generating device. Alternatively, the button on the device itself can act as the projection that makes typing easier. The receiving cavity of the aerosol generating device may have a cross-sectional shape that corresponds to the shape of the cross section of the aerosol generating device. The coding means can then result from an applied orientation relationship between the aerosol generating device and the receiving cavity.
    [0051] [0051] In an embodiment in which the aerosol generating device includes at least one tapered end, the tapered end allows the device to be more easily inserted into the cavity of the loading device.
    [0052] [0052] As used herein, the means plus the functional characteristics can be expressed alternatively in terms of their corresponding structure.
    [0053] [0053] Any characteristic related to one aspect can be applied to other aspects, in any suitable combination. In particular, method aspects can be applied to device aspects, and vice versa. In addition, any, some or all of the characteristics of an aspect can be applied to any, some or all of the characteristics, in any other aspect, in any suitable combination.
    [0054] [0054] It should also be understood that the particular combinations of the various characteristics described and defined in any aspect of the invention can be implemented or provided or used independently.
    [0055] [0055] These and other aspects of the device will be evident from the following exemplary modalities that are described with reference to the following figures in which:
    [0056] [0056] Figure 1 shows a perspective view of an embodiment of an aerosol generating device;
    [0057] [0057] Figure 2 shows a side view of the aerosol generating device shown in figure 1;
    [0058] [0058] Figures 3 (a) and 3 (b) show top views of the aerosol generating device shown in figures 1 and 2;
    [0059] [0059] Figures 4 (a) and 4 (b) illustrate a schematic diagram of the air flow through the aerosol generating device shown in figures 1, 2 and 3;
    [0060] [0060] Figure 5 shows an exploded view of the aerosol generating device shown in Figures 1, 2 and 3;
    [0061] [0061] Figures 6 (a) and 6 (b) illustrate a charging device, adapted to receive and charge the aerosol generating device shown in figures 1 to 5;
    [0062] [0062] Figures 7A to 7F illustrate exemplary cross sections of the device that can provide anti-roll functionality.
    [0063] [0063] Figure 1 shows a perspective view of an embodiment of an aerosol generating device 100. The device 100 is elongated and comprises two opposite polygonal end faces 102 and 104, respectively. The device 100 also comprises a button 106 adapted to activate the aerosol generating device, when pressed. The operation of the device is described in more detail below. As can be seen, the outer casing of the device 100 comprises four parts joined in the connecting lines 108, 110 and 112, respectively. The outer shell is formed from an aluminum alloy having a wall thickness of approximately 0.3 mm. The four parts, respectively, are a first conical end part 114 connected to a first central part 116, a second conical end part 120 connected to a second central part 118. The four parts fit around an internal structure (not shown) in a manner described below.
    [0064] [0064] Device 100 has a regular polygonal cross section over most of its length. However, in the 106 button region the cross section is not a regular polygon, but remains a simple polygon.
    [0065] [0065] Figure 2 shows a side view of the aerosol generating device 100 shown in figure 1. As can be seen, the button 106 projects from the surface of the device, so that the user can more easily push the button to activate the device in use.
    [0066] [0066] Figures 3 (a) and 3 (b) show the faces of the polygonal end 102 and 104 of the device 100, respectively. As can be seen, the polygon in this modality has ten sides, and this results in a device having ten faces that extend longitudinally. The button 106 has a triangular cross section and protrudes from one side of the housing. This means that there is a flat face on the opposite side of the device for the button, the device can therefore remain at rest with the button 106 upwards. Note that if the device were to have a cross section defined by a polygon with an odd number of sides, it may be preferable for the button to be defined between the faces in such a way that it can be higher when the device is lying down on a surface.
    [0067] [0067] Figure 3 (a) shows the end face 102 of the coupling part with five connectors or contacts 300. Connectors 300 can include one or more electrical connectors or one or more data connectors or a combination of electrical connectors and data connectors. The end face is part of an internal component of the device, which is retained within the housing. The electrical connectors are adapted to connect with a secondary charging device, which is described in more detail below. As can be seen, providing a polygonal cross section allows the five electrical connectors 300 to be more easily positioned on the end face 102 of the aerosol generating device 100.
    [0068] [0068] Figure 3 (b) shows the face of the end 104. A support 402 defining a cavity 302 is provided to accept an aerosol generating article comprising an aerosol forming substrate (not shown).
    [0069] [0069] Figures 4A and 4B show a schematic representation of the air flow through the device. Note that these values do not accurately describe the relative dimension of the device elements, for example, the air intake channels. As can be seen in this embodiment, when an aerosol generating article 304 is received inside the cavity 302 of the device 100 (figure 4B), the air drawn into the device passes around the outside of an aerosol generating article support. 402 located inside cavity 302. The support 402 has a circular cross section. The drawn air proceeds to the aerosol-forming substrate at the distal end of the smoking article adjacent to a heating plug 404 of a blade-shaped heating element 406 provided in cavity 302. The drawn air proceeds through the substrate, entraining the aerosol, and then to the mouth end of the smoking article. The air intakes 408 that form between the outer shell and the support 402 allow air to be drawn more efficiently and assist with the insulation of the heated aerosol generating article from the outer shell. Air intakes 408 can be seen schematically in figure 3 (b). Note that the entries may not be circular, but are described as circular in figure 3 (b), for clarity.
    [0070] [0070] Figure 5 shows an exploded view of the aerosol generating device 100. The device comprises a first outer casing part 500 which comprises the first tapered end part 114 and the first central part 116. The device further comprises a second outer casing part 502 comprising the second conical end part 120 and the second central part 118. The device also comprises an inner casing 504. The device also comprises a power supply in the form of a battery 506, a controller 508 adapted for control the power supplied by the battery 506 to a heating element (not shown) contained in a section of the inner shell 510. The button 106 is located on the part of the central shell 504 and engages with the controller 508, to allow the user to activate the device .
    [0071] [0071] In use, a user inserts an aerosol generating article 516 comprising an aerosol forming substrate 512 into cavity 302 of the aerosol generating device 100. The aerosol forming substrate 512 engages with the heating 406. When the user activates the device by the push button 106, energy is supplied to the heating element 406 from the battery 506 through the controller 508. The heating element 406 heats the aerosol forming substrate 512 to generate a aerosol, and the aerosol is entrenched within the air flow as the user drags at the mouth end 514 of the aerosol generating article 516.
    [0072] [0072] Figure 6A shows a perspective view of a loading device 600, adapted to receive and load the aerosol generating device 100. The loading device comprises a cavity 602, adapted to receive the aerosol generating device 100 , a power supply in the form of a battery 604, and a controller 606. When device 100 requires charging or data is to be transmitted between devices 100 and 600, device 100 is inserted into cavity 602, and connections 300 are coupled to the corresponding contacts 608 of contact plate 610 at the bottom of cavity 602. Figure 6B is a schematic diagram illustrating contact plate 610 of the loading device, which is located at the bottom of cavity 602. The plate contact can be seen as having five contacts 608, which correspond to the five contacts 300 in the aerosol generating device.
    [0073] [0073] The cavity 602 has a polygonal cross section, which corresponds to the cross section of the aerosol generating device 100. The cavity may alternatively have a substantially circular cross section of sufficient diameter to receive the device. In addition, the cavity is provided with a notch 612 that allows the button 106 of the device to be located inside the cavity 602. The button 106 on the device 100 allows the device to be fitted to the loading device 600 so that the device 100 can only be inserted into the loading device 600 in one orientation. When providing such encryption means, the user is prevented from inserting device 100 incorrectly, whereby correction links 300 from device 100 and contacts 610 are made each time device 100 is inserted into device 600. In addition In addition, the conical end portion 114 of the aerosol generating device 100 allows the user to insert the device more easily into cavity 602.
    [0074] [0074] It is clear that it is to be understood that the specification is not intended to be limited to the details of the above modalities which are described by way of example only.
    [0075] A preferred aerosol generating device can be substantially cylindrical. Figures 7A to 7F illustrate several exemplary cross sections that can impart anti-slip functionality to the device.
    [0076] [0076] Figure 7A, for example, is a drop shape. If this shape forms the base of a cylinder, the cylinder will have an outer surface that defines a single longitudinal line. Although the device may be able to roll on its curved outer part, it cannot roll any further for a complete revolution since the corner of the drop will collide on a surface.
