Abstract
Description
AEROSOL GENERATING APPARATUS COMPRISING A COMMUNICATION INTERFACEFIELD
[0001] The present disclosure relates to an aerosol generating apparatus.BACKGROUND
[0002] A typical aerosol generating apparatus may comprise a power supply, an aerosol generating unit that is driven by the power supply, an aerosol precursor, which in use is aerosolised by the aerosol generating unit to generate an aerosol, and a delivery system for delivery of the aerosol to a user.
[0003] Aerosol generating apparatuses may be equipped with radiofrequency communication capability, for example Low Energy (BLE) capability.
[0004] A drawback with known aerosol generating apparatuses having such communication capability is that the robust materials that a housing or body of an aerosol generating apparatus are typically made from materials that strongly attenuate radiofrequency waves that propagate through them.
[0005] In spite of the effort already invested in the development of aerosol generating apparatuses / systems further improvements are desirable.SUMMARY
[0006] The present disclosure provides an aerosol generating apparatus. The aerosol generating apparatus comprises: a housing; a processor mounted on a circuit board in the housing; a communication interface in the housing for communication with an external device via radiofrequency signals, wherein the communication interface is communicatively connected to the processor and is disposed at a position within the housing remote from the circuit board. The housing comprises a radiofrequency aperture aligned with the communication interface so as to facilitate the exchange of radiofrequency signals between the communication interface and the external device.
[0007] By positioning the communication interface remote from the circuit board on which the processor is mounted, it is possible to reduce the attenuation of communication signals between the communication interface and an external device. This also provides greater flexibility in determining the layout of internal components within the aerosol generating apparatus. This may also help to reduce the risk of exposing the processor in the housing to potential damage via physical access through the aperture.
[0008] By mounting the processor in the housing, the processor may be held in position within the housing, reducing the risk of the processor being dislodged from its position in use. This in turn reduces the risk that the processor, in use, becomes inadvertently aligned with the aperture, thereby exposing the processor to risk of damage via physical access through the aperture.
[0009] In some examples, the communication interface may be suitable for facilitating communication between the aerosol generating apparatus and an external device. Communication between the aerosol generating apparatus and an external device may be desirable as it may facilitate the provision of increased and more varied functionality for the aerosol generating apparatus, making it a more versatile device for the user.
[0010] Radiofrequency communication via radiofrequency signals, for example or Low Energy (BLE) communication, may be a particularly suitable or convenient means for communication, not least because it is widely used in personal devices, and it is straightforward to establish communicative connections using such signals.
[0011] In some examples, the communication interface may be communicatively connected to the processor. In this way communication between the processor and the external device may be achieved.
[0012] In some examples, the aperture in the housing may be a radiofrequency aperture. In other words, the aperture may be an aperture suitable for facilitating the exchange of radiofrequency signals between the communication interface and the external device. As discussed above, radiofrequency communication via radiofrequency signals, for example or BLE communication, may be a particularly suitable or convenient means for communication, not least because it is widely used in personal devices, and it is straightforward to establish communicative connections using such signals.
[0013] The aperture may be configured such that the communication signals exchanged between the communication interface and the external device are not attenuated (or at least not significantly attenuated) .
[0014] The aperture may be understood to be an aperture extending entirely through a wall of the housing, e.g., from an exterior of the housing to an interior of the housing.
[0015] In some examples, the circuit board on which the processor is mounted may be a printed circuit board. Printed circuit boards may be preferable as they are relatively inexpensive (both in terms of cost and materials) to manufacture, and can be reliably mass-produced, meaning that the aerosol generating apparatus described herein can also be reliably mass-manufactured and assembled.
[0016] In some examples, the printed circuit board may be rigid. In such examples, the printed circuit board on which the processor is mounted may not be a flexible printed circuit board.
[0017] In other examples, the printed circuit board may be a flexible printed circuit board.
[0018] In some examples, the communication interface may comprise a communication substrate, separate from the circuit board on which the processor is mounted. The communication substrate may be useable / configured to hold the communication interface in place within the housing, e.g., thereby preventing it from being dislodged when the aerosol generating apparatus is in use. In this way, the alignment of the communication interface with the aperture may be maintained, even when the aerosol generating apparatus is in use (and, for example, is dropped, thrown, hit, etc. ) .
[0019] In some examples, the communication substrate may be a printed circuit board. As discussed above, printed circuit boards may be particularly useful because they are relatively inexpensive (both in terms of cost and materials) to manufacture, and can be reliably mass-produced, meaning that the aerosol generating apparatus described herein can also be reliably mass-manufactured and assembled.
[0020] In some examples, the printed circuit board defining the communication substrate may be a flexible circuit board. By providing the communication substrate as a flexible printed circuit board, it may be possible to more conveniently install the communication interface in the housing. This is because the flexible printed circuit board may be able to flex around other components of the aerosol generating apparatus already in the housing. By providing this flexibility, it may be possible to provide a communication interface remote from the processor without unduly increasing the size of the aerosol generating apparatus.
[0021] In some examples, the communication interface may comprise an antenna for communication with the external device. The antenna may be located on the communication substrate (e.g., the antenna may be mounted on, adhered to, or printed on the communication substrate) . The communication substrate may be mounted within the housing so that the antenna is aligned with the aperture so as to facilitate the exchange of radiofrequency signals between the communication interface and the external device. Herein, the antenna being aligned with the aperture may be understood as the antenna being located in relation to the aperture such that the antenna is able to exchange radiofrequency signals with the external device via the aperture.
[0022] In some examples, the antenna may be aligned with the aperture such that the aperture overlays the antenna when the aerosol generating apparatus is viewed from a side of the aerosol generating apparatus that includes the aperture.
[0023] In some examples, the antenna may be formed from a ductile material (e.g., a metal wire) . In this way, the antenna may be sufficiently flexible to be manipulable to position the antenna such that it is aligned with the aperture. Further, the ductile material may be sufficiently durable that it is resistant to damage via physical access through the aperture.
[0024] In some examples, the communication substrate may be attached to an interior surface of the housing. This may help facilitate the alignment of the antenna with the aperture.
[0025] To facilitate such attachment, the communication substrate may be formed, at least in part, from a material that has self-adhesive properties which facilitate the attachment of the communication substrate to the interior surface of the housing. The interior surface of the housing may be a surface of a filler mounted in the aperture to fill the aperture (as discussed in more detail below) .
[0026] In some examples, the antenna may be defined by tracks embedded in, mounted on, or printed on the communication substrate.
[0027] In other examples, the antenna may be defined by a chip structure –i.e., the antenna may be included in a so-called “chip antenna” .
[0028] The aerosol generating apparatus may include communication circuitry configured to generate signals (e.g. RF signals) for broadcast by the antenna and / or process signals (e.g. RF signals) received by the antenna. The communication circuitry may take the form of a microcontroller or chip, such as a or BLE chip, for example. The signals may take the form of RF signals, e.g. or BLE signals, for example.
[0029] The processor may control operation of the communication circuitry.
[0030] In some examples, the communication interface may include the communication circuitry. The antenna may be included in the communication chip, or separate from the communication chip. The communication circuitry included in the communication interface may be mounted on a communication circuit board, separate from the circuit board on which the processor is mounted. The communication circuit board may be useable / configured to hold the communication interface in place within the housing, e.g. thereby preventing it from being dislodged when the aerosol generating apparatus is in use. In this way, the alignment of the communication interface with the aperture may be maintained, even when the aerosol generating apparatus is in use (and, for example, is dropped, thrown, hit, etc. ) .
[0031] In other examples, the communication circuitry may be located separately from the communication interface, with the communication circuitry coupled to the communication interface so as to allow (e.g. RF) signals to be communicated between the communication circuitry and (e.g. an antenna of the) communication interface. In some examples, the communication circuitry located separately from the communication interface may be mounted on the circuit board (e.g. it may be included in the processor mounted on the circuit board or may be a component separate from the processor which is independently mounted on the circuit board) .
[0032] In some examples, the coupling between the communication circuitry and the (e.g. antenna of the) communication interface may comprise a cable. The cable may extend through an interior of the housing.
[0033] In some examples, the cable may have a length of at least 3mm, more preferably at least 5 mm.
[0034] In some examples, the cable may be flexible.
[0035] In some examples, the cable may be a coaxial cable.
[0036] In some examples, the communication circuitry may not be aligned with the aperture so as to reduce the risk of the communication circuitry being damaged via physical access through the aperture.
[0037] In some examples, the processor may be disposed proximal to a first end of the aerosol generating apparatus, and the communication interface may be disposed proximal to a second end of the aerosol generating apparatus, the second end being distal from the first end.
[0038] In other words, the processor and the communication interface may be positioned at opposite ends of the aerosol generating apparatus. By positioning the processor and communication interface at opposite ends of the aerosol generating apparatus, and consequently the aperture at an opposite end of the aerosol generating apparatus to the processor, a risk of damage to the processor via physical access through the aperture may be further reduced.
[0039] In some examples, the aerosol generating apparatus may further comprise a mouthpiece for drawing aerosol (generated by the aerosol generating apparatus) therethrough, wherein the mouthpiece is disposed at the first end.
[0040] In other words, the processor may be positioned proximal to the end of the aerosol generating apparatus comprising the mouthpiece. In this way, the processor may be positioned proximal to one or more components of the aerosol generating apparatus (e.g., the power source, and / or the aerosol generation unit –such as a heating unit) , which may help to reduce the amount of circuity needed to connect the processor to those components (for the purpose of communication and / or for enabling the function of those components) , thereby facilitating the provision of an aerosol generating apparatus comprising the processor, without unduly increasing the size of the aerosol generating apparatus.
[0041] In some examples, an end of the housing proximal to the second end of the aerosol generating apparatus may be an open end (of the housing) . In this way, it may be possible to assemble the aerosol generating apparatus by inserting one or more components of the aerosol generating apparatus through the open end.
[0042] In some examples, the aperture may be defined by a cut out portion, cut out from the housing, wherein the cut-out portion extends from the open end of the housing towards the first end.
[0043] For avoidance of any doubt, the cut-out portion need not literally have been cut out from the housing, and may be formed in other ways (e.g., by forming the housing with the cut-out portion being already present) . Also, for the avoidance of any doubt, the aperture ( / cut out portion) need may be formed at an end of the housing, e.g., such that it might not be surrounded on all sides by the material of the housing.
[0044] In some examples, the aerosol generating apparatus may further comprise an insert fitted into the open end of the housing. The insert may, for example, be provided in the aerosol generating apparatus by pushing the insert into the open end, e.g., thereby completing assembly of the aerosol generating apparatus. The insert may be affixable to the housing, for example, by a push-fit mechanism. The insert may, for example, by flared to prevent removal of the insert after it has been inserted into the open end of the housing.
[0045] In some examples, the aerosol generating apparatus may further comprise a charging interface (for charging the aerosol generating apparatus) . The charging interface may be located in the housing.
[0046] The charging interface may be connected to a power source in the housing.
[0047] In some examples, the charging interface may be a wired charging interface (e.g., for charging the power source via a cable) or wireless charging interface (e.g., for charging the power source wirelessly) .
[0048] In some examples, the charging interface may be located in the second (open) end of the housing.
[0049] In some examples, the charging interface may be a charging port. For example, the charging port may be a wired charging port defining a port for receiving a charging cable therein to charge the aerosol generating apparatus. In some examples, the charging port may be a port configured to receive an industry-standard charging cable, for example USB-C type charging cable.
[0050] In some examples, the charging interface may be disposed at the second end of the aerosol generating apparatus. In this way, the communication interface and the charging interface may be positioned proximal to each other. The communication interface may be positioned, in some examples, to fit around the charging interface.
[0051] In some examples, the charging interface may be included in (e.g., be mounted in) the insert. For example, the charging interface may be a charging port for receiving a charging cable, the port mounted in the inert. In this way, the charging interface may be easily assembled into the aerosol generating apparatus by inserting the insert into the second (open) end of the housing.
[0052] In some examples, the aerosol generating apparatus may further comprise a filler mounted in the aperture to fill the aperture. The filler may be formed form a material different from the material that the housing is formed from. The material from which the filler is formed may be configured to allow communication signals (e.g., radiofrequency signals) to propagate therethrough.
[0053] In other words, the filler may be formed from a material that is more transparent to the communication signals exchanged to / from the communication interface than the material used to form the housing.
[0054] For example, the housing may, in some examples, be formed from a metal such as aluminium or another suitable material. Metals may be fully opaque (and may indeed be reflective) to communication signals such as radiofrequency signals. It may be suitable to provide the housing with a metal material because it is a material that is robust against physical damage caused, for example, by dropping, throwing or hitting the housing.
[0055] The filler may, in some examples, be formed from a non-conductive material such as a plastic or other suitable material. Non-conductive materials (e.g., suitable dielectrics such as plastics) may provide a material that is transparent (or at least sufficiently transparent) to communication signals such as radiofrequency signals to permit communication between the communication interface and an external device.
[0056] The filler may include a surface which forms part of an outer surface of the aerosol generating apparatus. This surface of the filler may be configured to form a continuous surface with an outer surface of the housing.
[0057] In some examples, the filler may be formed from a waterproof material such as plastic or rubber to inhibit moisture from entering the aerosol generating apparatus and damaging any components and / or circuity disposed inside the housing.
[0058] In some examples, the communication substrate (if present) may be adhered to the filler. In this way, it may be possible to more securely achieve alignment of an antenna located on the communication substrate with the aperture, thereby facilitating an improved strength for any communication signals exchanged between the aerosol generating apparatus and any external device.
[0059] In some examples, the aerosol generating apparatus may have a first side and a second side. The first and second sides may face in opposite directions. The aperture may be located only on one of the first and second sides.
[0060] In other words, the housing may comprise one or more side walls connecting the first and second ends of the housing. The one or more side walls may define a cross-section for the housing. The cross-section may be a suitable shape –for example the cross-section may be circular, elliptical, a vesica piscis (i.e., a pointed oval or almond-shaped) , a square, rectangular, triangular, or any other suitable shape.
[0061] The one or more side walls of the housing may be considered to define two sides of the housing, each facing in mutually opposite direction. The aperture may be formed in only one side of the housing, e.g. so as to minimise the number of angles of approach by which physical access through the aperture can be achieved. In this way, the risk of damage to one or more components of the aerosol generating apparatus in the housing via physical access through the aperture may be reduced.
[0062] In some examples, the insert (as described above) may comprise the filler. The insert may be shaped and sized to extend from the open end of the housing along a side of the housing to the aperture. In this way, the filler may be inserted into (and fill) the aperture as the insert is inserted into the second (open) end of the housing to fill said second (open) end.
[0063] The insert comprising the filler may form a chassis to which one or other components of the aerosol generating apparatus, e.g., the circuit board on which the processor is mounted, are mounted.
[0064] In some examples, the filler may be at least partially flared to prevent the filler from being removed from the aperture.
[0065] In some examples, the filler may define a waterproof seal that seals the aperture and prevents moisture from entering an interior of the housing and damaging one or more components and / or circuitry of the aerosol generating apparatus contained within the housing.
[0066] In some examples the insert comprising the filler may be defined by a single moulded body.
[0067] In other words, the insert comprising the filler may be defined by a contiguous moulded part that is shaped and sized to be inserted into the second (open) end of the housing and into the aperture either simultaneously or one after another.
[0068] For example, the filler may be connected to a main body of the insert by a flexible connecting member that allows the manufacturer of the aerosol generating device to insert the insert into the second (open) end of the housing (e.g., by pushing the insert into the second open end) , and then manipulating the flexible connecting member to manoeuvre the filler into the aperture.
[0069] In some examples, there may be provided a system comprising the aerosol generating apparatus as described herein and one or more external devices (e.g., personal user devices such as mobile phones, tablets, or laptops) configured to communicate with the aerosol generating apparatus.
[0070] In some examples, the system may further comprise a server communicatively connected to the external device and / or the aerosol generating apparatus.

Accordingly, the above-described features should not be construed to narrow the scope or spirit of the subject matter described herein in any way. Moreover, the above and / or proceeding examples may be combined in any suitable combination to provide further examples, except where such a combination is clearly impermissible or expressly avoided.

[0100] As used herein, a "flow path" may refer to a path or enclosed passageway through an aerosol generating apparatus, e.g., for delivery of an aerosol to a user. The flow path may be arranged to receive aerosol from an aerosol generating unit. When referring to the flow path, upstream and downstream may be defined in respect of a direction of flow in the flow path, e.g., with an outlet being downstream of an inlet.

[0116] Referring to Fig. 1, an example aerosol generating apparatus 1 includes a power supply 2, for supply of electrical energy. The apparatus 1 includes an aerosol generating unit 4 that is driven by the power supply 2. The power supply 2 may include an electric power supply in the form of a battery and / or an electrical connection to an external power source. The apparatus 1 includes a precursor 6, which in use is aerosolised by the aerosol generating unit 4 to generate an aerosol. The apparatus 2 includes a delivery system 8 for delivery of the aerosol to a user.
[0117] Electrical circuitry (not shown in figure 1) may be implemented to control the interoperability of the power supply 4 and aerosol generating unit 6.
[0118] In variant examples, which are not illustrated, the power supply 2 may be omitted since, e.g. an aerosol generating unit implemented as an atomiser with flow expansion may not require a power supply.
[0119] Fig. 2 shows an implementation of the apparatus 1 of Fig. 1, where the aerosol generating apparatus 1 is configured to generate aerosol from a liquid precursor.
[0120] In this example, the apparatus 1 includes a device body 10 and a consumable 30.
[0121] In this example, the body 10 includes the power supply 4. The body may additionally include any one or more of electrical circuitry 12, a memory 14, a wireless interface 16, one or more other components 18.
[0122] The electrical circuitry 12 may include a processing resource for controlling one or more operations of the body 10 and consumable 30, e.g., based on instructions stored in the memory 14.
[0123] The wireless interface 16 may be configured to communicate wirelessly with an external (e.g., mobile) device, e.g., via or BLE communication.
[0124] The other component (s) 18 may include one or more user interface devices configured to convey information to a user and / or a charging port, for example (see e.g., Fig. 3) .
[0125] The consumable 30 includes a storage portion implemented here as a tank 32 which stores the liquid precursor 6 (e.g., e-liquid) . The consumable 30 also includes a heating system 34, one or more air inlets 36, and a mouthpiece 38. The consumable 30 may include one or more other components 40.
[0126] The body 10 and consumable 30 may each include a respective electrical interface (not shown) to provide an electrical connection between one or more components of the body 10 with one or more components of the consumable 30. In this way, electrical power can be supplied to components (e.g., the heating system 34) of the consumable 30, without the consumable 30 needing to have its own power supply.
[0127] In use, a user may activate the aerosol generating apparatus 1 when inhaling through the mouthpiece 38, i.e., when performing a puff. The puff, performed by the user, may initiate a flow through a flow path in the consumable 30 which extends from the air inlet (s) 34 to the mouthpiece 38 via a region in proximity to the heating system 34.
[0128] Activation of the aerosol generating apparatus 1 may be initiated, for example, by an airflow sensor in the body 10 which detects airflow in the aerosol generating apparatus 1 (e.g., caused by a user inhaling through the mouthpiece) , or by actuation of an actuator included in the body 10. Upon activation, the electrical circuitry 12 (e.g., under control of the processing resource) may supply electrical energy from the power supply 2 to the heating system 34 which may cause the heating system 32 to heat liquid precursor 6 drawn from the tank to produce an aerosol which is carried by the flow out of the mouthpiece 38.
[0129] In some examples, the heating system 34 may include a heating filament and a wick, wherein a first portion of the wick extends into the tank 32 in order to draw liquid precursor 6 out from the tank 32, wherein the heating filament coils around a second portion of the wick located outside the tank 32.
[0130] The heating filament may be configured to heat up liquid precursor 6 drawn out of the tank 32 by the wick to produce the aerosol.
[0131] In this example, the aerosol generating unit 4 is provided by the above-described heating system 34 and the delivery system 8 is provided by the above-described flow path and mouthpiece 38.
[0132] In variant embodiments (not shown) , any one or more of the precursor 6, heating system 34, air inlet (s) 36 and mouthpiece 38, may be included in the body 10. For example, the mouthpiece 38 may be included in the body 10 with the precursor 6 and heating system 32 arranged as a separable cartomizer.
[0133] Figs. 3a and 3b show an example implementation of the aerosol generating device 1 of Fig. 2. In this example, the consumable 30 is implemented as a capsule / pod, which is shown in Fig. 3a as being physically coupled to the body 10, and is shown in Fig. 3b as being decoupled from the body 10.
[0134] In this example, the body 10 and the consumable 30 are configured to be physically coupled together by pushing the consumable 30 into an aperture in a top end 11 the body 10, with the consumable 30 being retained in the aperture via an interference fit.
[0135] In other examples (not shown) , the body 10 and the consumable 30 could be physically coupled together in other ways, e.g., by screwing one onto the other, through a bayonet fitting, or through a snap engagement mechanism, for example.
[0136] The body 10 also includes a charging port (not shown) at a bottom end 13 of the body 10.
[0137] The body 10 also includes a user interface device configured to convey information to a user. Here, the user interface device is implemented as a light 15, which may e.g., be configured to illuminate when the apparatus 1 is activated. Other user interface devices are possible, e.g., to convey information haptically or audibly to a user.
[0138] In this example, the consumable 30 has an opaque cap 31, a translucent tank 32 and a translucent window 33. When the consumable 30 is physically coupled to the body 10 as shown in Fig. 3A, only the cap 31 and window 33 can be seen, with the tank 32 being obscured from view by the body 10.
[0139] The body 10 includes a slot 15 to accommodate the window 33. The window 33 is configured to allow the amount of liquid precursor 6 in the tank 32 to be visually assessed, even when the consumable 30 is physically coupled to the body 10.
[0140] Fig. 4 shows an implementation of the apparatus 1 of Fig. 1, where the aerosol generating apparatus 1 is configured to generate aerosol by a-heat not-burn process.
[0141] In this example, the apparatus 1 includes a device body 50 and a consumable 70.
[0142] In this example, the body 50 includes the power supply 4 and a heating system 52. The heating system 54 includes at least one heating element 54. The body may additionally include any one or more of electrical circuitry 56, a memory 58, a wireless interface 60, one or more other components 62.
[0143] The electrical circuitry 56 may include a processing resource for controlling one or more operations of the body 50, e.g. based on instructions stored in the memory 58.
[0144] The wireless interface 60 may be configured to communicate wirelessly with an external (e.g. mobile) device, e.g. via Bluetooth.
[0145] The other component (s) 62 may include an actuator, one or more user interface devices configured to convey information to a user and / or a charging port, for example (see e.g. Fig. 5) .
[0146] The body 50 is configured to engage with the consumable 70 such that the at least one heating element 54 of the heating system 52 penetrates into the solid precursor 6 of the consumable. In use, a user may activate the aerosol generating apparatus 1 to cause the heating system 52 of the body 50 to cause the at least one heating element 54 to heat the solid precursor 6 of the consumable (without combusting it) by conductive heat transfer, to generate an aerosol which is inhaled by the user.
[0147] Fig. 5 shows an example implementation of the aerosol generating device 1 of Fig. 4.
[0148] As depicted in Fig. 5, the consumable 70 is implemented as a stick, which is engaged with the body 50 by inserting the stick into an aperture at a top end 53 of the body 50, which causes the at least one heating element 54 of the heating system 52 to penetrate into the solid precursor 6.
[0149] The consumable 70 includes the solid precursor 6 proximal to the body 50, and a filter distal to the body 50. The filter serves as the mouthpiece of the consumable 70 and thus the apparatus 1 as a whole. The solid precursor 6 may be a reconstituted tobacco formulation.
[0150] In this example, the at least one heating element 54 is a rod-shaped element with a circular transverse profile. Other heating element shapes are possible, e.g., the at least one heating element may be blade-shaped (with a rectangular transverse profile) or tube-shaped (e.g., with a hollow transverse profile) .
[0151] In this example, the body 50 includes a cap 51. In use the cap 51 is engaged at a top end 53 of the body 50. Although not apparent from Fig. 5, the cap 51 is moveable relative to the body 50. In particular, the cap 51 is slidable and can slide along a longitudinal axis of the body 50.
[0152] The body 50 also includes an actuator 55 on an outer surface of the body 50. In this example, the actuator 55 has the form of a button.
[0153] The body 50 also includes a user interface device configured to convey information to a user. Here, the user interface device is implemented as a plurality of lights 57, which may e.g., be configured to illuminate when the apparatus 1 is activated and / or to indicate a charging state of the power supply 4. Other user interface devices are possible, e.g., to convey information haptically or audibly to a user.
[0154] The body may also include an airflow sensor which detects airflow in the aerosol generating apparatus 1 (e.g., caused by a user inhaling through the consumable 70) . This may be used to count puffs, for example.
[0155] In this example, the consumable 70 includes a flow path which transmits aerosol generated by the at least one heating element 54 to the mouthpiece of the consumable.
[0156] In this example, the aerosol generating unit 4 is provided by the above-described heating system 52 and the delivery system 8 is provided by the above-described flow path and mouthpiece of the consumable 70.
[0157] Fig. 6 shows an example system 80 for managing an aerosol generating apparatus 1, such as those described above with reference to any of Figs. 1-5.
[0158] The system 80 as shown in Fig. 1 includes a mobile device 82, an application server 84, an optional charging station 86, as well as the aerosol generating apparatus 1.
[0159] In this example, aerosol generating apparatus 1 is configured to communicate wirelessly, e.g. via BluetoothTM, with an application (or “app” ) installed on the mobile device 2, via a wireless interface included in the aerosol generating apparatus 1 and via a wireless interface included in the mobile device 82. The mobile device 82 may be a mobile phone, for example. The application on the mobile phone is configured to communicate with the application server 84, via a network 88. The application server 84 may utilise cloud storage, for example.
[0160] The network 88 may include a cellular network and / or the internet.
[0161] In other examples, the aerosol generating apparatus 1 may be configured to communicate with the application server 84 via a connection that does not involve the mobile device 82, e.g., via a narrowband internet of things ( “NB-IoT” ) or satellite connection. In some examples, the mobile device 82 may be omitted from the system 80.
[0162] A skilled person would readily appreciate that the mobile device 82 may be configured to communicate via the network 88 according to various communication channels, preferably a wireless communication channel such as via a cellular network (e.g., according to a standard protocol, such as 3G or 4G) or via a WiFi network.
[0163] The app installed on the mobile device 82 and the application server 84 may be configured to assist a user with managing their aerosol generating apparatus 1, based on information communicated between the aerosol generating apparatus 1 and the app, information communicated directly between the aerosol generating apparatus 1 and the application server 84, and / or information communicated between the app and the application server 84.
[0164] The charging station 86 (if present) may be configured to charge (and optionally communicate with) the aerosol generating apparatus 1, via a charging port on the aerosol generating apparatus 1. The charging port on the smoking substitute device 10 may be a USB port, for example, which may allow the aerosol generating apparatus 1 to be charged by any USB-compatible device capable of delivering power to the aerosol generating apparatus 1 via a suitable USB cable (in this case the USB-compatible device would be acting as the charging station 86) . Alternatively, the charging station could be a docking station specifically configured to dock with the aerosol generating apparatus 1 and charge the aerosol generating apparatus 1via the charging port on the aerosol generating apparatus 1.
[0165] Fig. 7 shows a schematic view of a housing 102 of an aerosol generating apparatus 1. In this example, the housing 102 is suitable for use as a housing for the body 10 of the aerosol generating apparatus 1 described with reference to Fig. 2 above. However, it is also possible for an analogous housing to be used as the body of the aerosol generating apparatus 1 described with reference to Fig. 5, above.
[0166] The housing 102 of Fig. 7 is shown having a circular cross-section and flat first and second ends 104, 106. The skilled person will appreciate that these shapes are merely schematic and other cross-sections (e.g., elliptical, almond-shaped, square, rectangular, triangular, etc. ) are possible and that the first and second ends 104, 106 may be pointed, rounded or otherwise shaped. The skilled person will also appreciate that the first and second ends 104, 106 need not have the same shape. For example, the mouthpiece 38 of the aerosol generating apparatus 1 may be provided at the first end 104. Conversely, the second end 106 of the aerosol generating apparatus 1 may be an open end, into which various components of the aerosol generating apparatus 1 may be inserted during the manufacture / assembly of the aerosol generating apparatus 1.
[0167] The housing 102 may be formed from a material such as metal (e.g., aluminium) that is opaque (and may indeed be reflective) to communication signals such as radiofrequency signals. To permit communication between the aerosol generating apparatus 1 and an external device (e.g., the external device 82 described above in relation to Fig. 6) , an aperture 108 –also referred to as a radiofrequency (or “RF” ) aperture 108 –is provided in the housing 102. In this example, the aperture 108 is formed in only one side of the housing (this being the side of the housing depicted in Fig. 7) . As shown in Fig. 7, the aperture may be defined by a cut-out portion cut out from the housing 102, extending from the second (open) end 106 of the housing 102 towards the first end 104. The skilled person will, however, appreciate that the aperture 108 need not be continuously connected with the second end 106, and may instead be separate from the second end 106. In such cases, the aperture may be any suitable size and / or shape (e.g., circular, square, elliptical, rectangular, etc. ) to permit communication signals such as radiofrequency signals to propagate therethrough.
[0168] Fig. 8a and Fig. 8b show schematic views of the housing 102 of Fig. 7 further comprising an insert 110, wherein the insert 110 comprises a filler 112 for the aperture, wherein a charging interface 114 of the aerosol generating apparatus 1 is mounted in the insert 110. The body of the insert 110 and the filler 112 may be defined by a single moulded body. Fig. 8a shows a side-on view of the housing 102 plus insert 110, whereas Fig. 8b shows a view of the housing 102 plus insert 110 from the second end 106 of the housing 104.
[0169] The insert 110 (and correspondingly the filler 112) may be formed from any suitable material, for example a dielectric such as a plastic, rubber, or other polymer. The filler 112 may be transparent (or at least substantially transparent) to communication signals such as radiofrequency signals to facilitate communication between the aerosol generating apparatus 1 and the external device 82. By this, it is meant that the material from which the filler 112 is formed does not attenuate the communication signal –such as a radiofrequency signal –to such a degree that the aerosol generating apparatus 1 and the external device 82 are unable to communicate with each other.
[0170] The insert 110 and / or the filler 112 may be formed from a material suitable for establishing a waterproof seal that seals the second (open) end 106 and / or the aperture 108 to prevent moisture from entering the interior of the housing 102 of the aerosol generating apparatus 1.
[0171] In some examples, as discussed above, the body of the insert 110 and / or filler 112 may be insertable by a push-fit type mechanism. Additionally or alternatively, the body of the insert 110 and / or filler 112 may comprise one or more flared portions to prevent the insert 110 and / or filler 112 from being respectively removed from the second (open) end 106 and / or the aperture 108 after insertion.
[0172] As noted above, the insert 110 comprises a charging interface 114 for charging a power supply 2 of the aerosol generating apparatus 1 mounted therein. In this example, the charging interface 114 is a wired charging interface, specifically a charging port suitable for receiving a charging cable for charging a power supply 2 of the aerosol generating apparatus 1. For example, the charging interface 114 may be a wired port suitable for receiving a USB-C type charging cable therein.
[0173] Fig. 9 shows a schematic of an interior of the housing 102 of Fig. 7 with a processor 120 connected to a communication interface 130, each disposed at opposite ends of the housing. In Fig. 9, a consumable 30 is (schematically) shown as being physically coupled to the first end 104 of the housing 102.
[0174] As can be seen from Fig. 9 the processor 120 is mounted on a circuit board 122 proximal to the first end 104 of the housing. The processor 120 may be operable connected to one or more of the components of the aerosol generating apparatus 1, such as any of the components discussed above in relation to Figs. 1 to 6.
[0175] The circuit board 122 may, in some examples, be a printed circuit board.
[0176] The interior of the housing 102 further includes a communication interface 130. The communication interface 130 is configured to facilitate communication (e.g., radiofrequency communication) between the aerosol generating apparatus 1 and the external device 82. As can be seen from Fig. 9, the communication interface 130 is positioned at a position within the housing 102 remote from the circuit board 122 on which the processor 120 is mounted. For example, the communication interface 130 may be disposed within the housing 102 proximal to the second end 106 of the housing 102.
[0177] In this example, the communication interface 130 comprises an (optionally flexible) communication substrate 132 having an antenna 134 located thereon. The antenna 134 may be mounted on, adhered to, or printed on the communication substrate 132.
[0178] In this example, the circuit board 122 comprises communication circuitry, in the form of a BLE chip 124, configured to generate BLE signals for broadcast by the antenna 134 and / or to process BLE signals received by the antenna 134. The BLE chip 124 is coupled to the antenna 134 on the communication substrate 132 via a coupling, which in this example is a coaxial cable 140, to allow BLE signals to be communicated between the BLE chip 124 and the antenna 134.
[0179] In this example, the communication substrate 132 is formed, at least in part, from a material that has self-adhesive properties which facilitate an attachment of the communication substrate 132 to the filler 112. This attachment helps to facilitate the alignment of the antenna 134 with the aperture 108. The profile of the aperture 108 is drawn in dashed lines on Fig. 9, which shows that in this example the aperture 108 is shaped and sized to overlay the antenna 134 of the communication interface 130 when the aerosol generating apparatus 1 is viewed from a side of the aerosol generating apparatus that includes the aperture, such that communication signals –such as radiofrequency signals –can be exchanged between the communication interface 130 and the external device 82.
[0180] In this example, the BLE chip 124 is configured to exchange radiofrequency signals such as BLE communication signals with the external device 82 via the via the coaxial cable 140 and the antenna 134.
[0181] The BLE chip 124 may be communicatively connected to the processor 120, so that the processor 120 can control operation of the BLE chip 124.
