Definitions

  • the present invention relates to smoking substitute devices.
  • it relates to the management of power supply to components of smoking substitute devices.
  • the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
  • Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
  • the filter typically comprises a filtration material which is circumscribed by a plug wrap.
  • the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
  • a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
  • Such smoking substitute devices can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Smoking substitute devices may comprise electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a "vapour") that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • aerosol also referred to as a "vapour”
  • the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
  • smoking substitute devices are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and tobacco products.
  • Some smoking substitute systems use smoking substitute articles (also referred to as a "consumables”) that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
  • smoking substitute devices are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end. Other smoking substitute devices do not generally resemble a cigarette (for example, the smoking substitute device may have a generally box-like form).
  • a smoking substitute approach corresponds to the manner in which the substitute system operates for a user.
  • vaping in which a vapourisable liquid, typically referred to (and referred to herein) as “e-liquid”, is heated by a heating device to produce an aerosol vapour which is inhaled by a user.
  • An e-liquid typically includes a base liquid as well as nicotine and/or flavourings.
  • the resulting vapour therefore typically contains nicotine and/or flavourings.
  • the base liquid may include propylene glycol and/or vegetable glycerin.
  • a typical vaping smoking substitute device includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating device.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating device.
  • electrical energy is supplied from the power source to the heating device, which heats the e-liquid to produce an aerosol (or "vapour") which is inhaled by a user through the mouthpiece.
  • Vaping smoking substitute devices can be configured in a variety of ways.
  • there are "closed system" vaping smoking substitute devices which typically have a sealed tank and heating element which is pre-filled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute devices include a main body which includes the power source, wherein the main body is configured to be physically and electrically coupled to a consumable including the tank and the heating element. In this way, when the tank of a consumable has been emptied, the main body can be reused by connecting it to a new consumable.
  • Another subset of closed system vaping smoking substitute devices are completely disposable, and intended for one-use only.
  • vaping smoking substitute devices which typically have a tank that is configured to be refilled by a user, so the device can be used multiple times.
  • An example vaping smoking substitute device is the mybluTM e-cigarette.
  • the mybluTM e-cigarette is a closed system device which includes a main body and a consumable.
  • the main body and consumable are physically and electrically coupled together by pushing the consumable into the main body.
  • the main body includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heating device, which for this device is a heating filament coiled around a portion of a wick which is partially immersed in the e-liquid.
  • the device is activated when a microprocessor on board the main body detects a user inhaling through the mouthpiece. When the device is activated, electrical energy is supplied from the power source to the heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • the blu PROTM e-cigarette is an open system device which includes a main body, a (refillable) tank, and a mouthpiece.
  • the main body and tank are physically and electrically coupled together by screwing one to the other.
  • the mouthpiece and refillable tank are physically coupled together by screwing one of the other, and detaching the mouthpiece from the refillable tank allows the tank to be refilled with e-liquid.
  • the device is activated by a button on the main body. When the device is activated, electrical energy is supplied from the power source to a heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • HT Heated Tobacco
  • HNB Heat not burn
  • the tobacco may be leaf tobacco or reconstituted tobacco.
  • the vapour may contain nicotine and/or flavourings.
  • the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
  • a typical HT smoking substitute system may include a device and a consumable.
  • the consumable may include the tobacco material.
  • the device and consumable may be configured to be physically coupled together.
  • heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes components in the tobacco material to be released as vapour.
  • a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) and additionally volatile compounds released from the tobacco.
  • the released vapour may be entrained in the airflow drawn through the tobacco.
  • the vapour passes through the consumable (entrained in the airflow) from the location of vaporisation to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
  • the aerosol will normally contain the volatile compounds.
  • HT smoking substitute systems heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • the IQOSTM smoking substitute device uses a consumable, including reconstituted tobacco located in a wrapper.
  • the consumable includes a holder incorporating a mouthpiece.
  • the consumable may be inserted into a main body that includes a heating device.
  • the heating device has a thermally conductive heating knife which penetrates the reconstituted tobacco of the consumable, when the consumable is inserted into the heating device. Activation of the heating device heats the heating element (in this case a heating knife), which, in turn, heats the tobacco in the consumable.
  • the heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the mouthpiece by the user through inhalation.
  • a second example of the HT approach is the device known as "Glo"TM from British American Tobacco p.l.c. GloTM comprises a relatively thin consumable.
  • the consumable includes leaf tobacco which is heated by a heating device located in a main body. When the consumable is placed in the main body, the tobacco is surrounded by a heating element of the heating device. Activation of the heating device heats the heating element, which, in turn, heats the tobacco in the consumable. The heating of the tobacco causes it to release nicotine vapour and flavourings which may be drawn through the consumable by the user through inhalation.
  • the tobacco when heated by the heating device, is configured to produce vapour when heated rather than when burned (as in a smoking apparatus, e.g. a cigarette).
  • the tobacco may contain high levels of aerosol formers (carrier), such as vegetable glycerine ("VG”) or propylene glycol ("PG").
  • the present inventor(s) have observed that most smoking substitute devices currently on the market are configured to operate in isolation of other devices, which limits the functions the smoking substitute devices can perform.
  • smoking substitute devices require intelligent management, to prevent wasting power when they are not in active use, for example during transportation.
  • the present invention has been devised in light of the above considerations.
  • the present invention provides a device and method that enable intelligent, sophisticated control of a smoking substitute device and ensure that power is not used unnecessarily, when the device is not in active use, or when certain functions are not required.
  • the smoking substitute device can be configured so that it enters a shipping mode, in which it can restrict power supply to one or more auxiliary components within the device, in order to prevent power being used by them at a time at which a user will not require them.
  • the restriction may comprise limiting the power supply to the auxiliary component or entirely preventing it.
  • the device may be configured to transition from a shipping mode to an active mode, when it detects that the user wishes to use the device, or that the user has otherwise performed an action or combination of actions to indicate that the device should enter an active mode.
  • the smoking substitute device may be configured to distinguish between a time at which no inhalations are being detected because, for example, the device is in transport - for example, after manufacture and testing and before first purchase or first use of the device by a user - and a time at which because the device is owned/possessed by a user, but no inhalations are being detected due to the user's usage choices.
  • the smoking substitute device may be configured to require detection of more than one action or condition, for it to transition to active mode. For example, it may require detection of an inhale and activation of another sensor or detector, for example the detection of a valid resistance coil being coupled to the main body of the device, which is indicative that a consumable has been inserted into the device. By requiring this double layer of detection, the device helps to avoid a false transition out of shipping mode. Therefore, power conservation is improved.
  • smoking substitute device comprising a body housing a power source, an auxiliary component, and an airflow sensor for detecting airflow through the body.
  • the body includes a coupling portion arranged to receive a consumable.
  • the body is selectively operable in a shipping mode and an active mode.
  • the power source is configured to supply power to the auxiliary component.
  • the power source is restricted from supplying power to the auxiliary component.
  • the body is configured to transition from the shipping mode to the active mode upon detection of: a consumable received in the coupling portion; and a flow of air through the body.
  • the smoking substitute device may be configured so that it will only transition from the shipping mode to the active mode if it detects both a consumable received in the coupling portion and a flow of air through the body.
  • the smoking substitute device may be configured so that the power source is also restricted from supplying power to a heating element within the device, when it is in shipping mode, to prevent or restrict smoking substitute action.
  • the smoking substitute device may be configured so that the power source is restricted from supplying power to the consumable, as well as to the auxiliary component, when it is in shipping mode.
  • the coupling portion may be configured to electrically couple with the consumable.
  • the coupling portion of the body may comprise an electrical interface for electrically connecting to an electrical interface of a consumable.
  • the electrical interface may comprise a pair of electrical contacts.
  • the body may be configured to monitor an electrical property the coupling portion to detect whether or not a consumable is received in the coupling portion.
  • the body may be configured to determine that the body is electrically coupled with a consumable by detecting a change in any of current or voltage or resistance at the electrical interface.
  • the coupling portion may be configured to mechanically couple with the consumable. Any suitable mechanical coupling may be employed, for example an interference fit, a screw fit, a snap fit, a bayonet fit, a push fit, or an interlocking fit.
  • the power supply from the power source to the auxiliary component may be prevented.
  • the power supply from the power source to the auxiliary component may be restricted or limited.
  • the body may be configured to supply power to the auxiliary component at a restricted low level when the body is in shipping mode.
  • the body may be configured to supply power to the auxiliary component for a restricted period of time after the body has entered shipping mode.
  • the auxiliary component may comprise any suitable component, within a smoking substitute device, the function or purpose of which is auxiliary, or additional, to the device's core function of heating a liquid or tobacco for smoking substitute action.
  • the auxiliary component may comprise a communications interface such as a wireless interface, for example a Wi-Fi or BluetoothTM interface.
  • the auxiliary component may comprise a position or orientation sensor such as an accelerometer, a magnetometer or a gyroscope.
  • the auxiliary component may comprise a user interface such as an LED screen, light or audio emitter.
  • the auxiliary component may comprise a data reader such as a bar code reader, for example for reading data from a consumable inserted into the smoking substitute device.
  • the airflow sensor may be positioned in an airflow channel extending through the body of the smoking substitute device.
  • the smoking substitute device may be provided with or without a button or a switch, for activating its operation. Therefore, it may not require a dedicated user input component (e.g. actuation of a button or switch) in order to switch the device on. Instead, it may rely on the detection of an inhale by the airflow sensor, preferably in combination with another detection such as the detection of a consumable being received in the coupling portion, in order to activate operation of the device for a smoking substitute action.
  • the smoking substitute device may be configured to transition from the active mode to the shipping mode if the airflow sensor does not detect a flow of air through the body for a predetermined period of time.
  • the smoking substitute device may be configured to detect whether a consumable is received in the coupling portion and, in accordance with that detection, either transition from the active mode to the shipping mode after a first predetermined period of time, if it has detected that a consumable is received in the coupling portion and if the airflow sensor does not detect a flow of air through the main body; or to transition from the active mode to the shipping mode after a second, different predetermined period of time, if it has detected that a consumable is not received in the coupling portion and if the airflow sensor does not detect a flow of air through the main body.
  • the first time period may be longer than the second time period.
  • the time period for which the device allows itself to remain "active", in the absence of an inhalation may vary dependent on whether or not a consumable is currently inserted in the device.
  • the device may be configured to use its determination as to whether or not there is a consumable inserted as an indicator of whether or not it is likely that the user intends to use the device again in the short to medium term, and therefore as a determining factor in how long it will wait before transitioning to shipping mode.
  • This also reflects the widely accepted practice of shipping smoking substitute devices, after manufacture and testing, without consumables inserted therein. Therefore, if a smoking substitute device has been in an active mode during testing, once it is packaged up without a consumable, for transportation to a retailer or end user, it may relatively quickly determine that it does not need to be in active mode, and therefore transition to shipping mode.
  • the active mode of the smoking substitute device may include different sub-modes.
  • it may comprise a first sub-mode, which may be referred to as a "use mode" in which, when the body is in active mode, power can be supplied to the consumable.
  • the active mode may comprise a second sub-mode, which may be referred to as a "standby mode” in which power is supplied to the auxiliary device but not to the consumable. In such a configuration, the device would therefore not enable liquid or tobacco to be heated for smoking substitute action, when it is in standby mode.
  • the smoking substitute device may be configured to transition from use mode to standby mode, if the airflow sensor has not detected an inhale, i.e. an airflow through the body, for a pre-determined first period of time.
  • the smoking substitute device may further be configured to transition from standby mode to shipping mode if the airflow sensor has still not detected an inhale after a pre-determined second (additional) amount of time.
  • the smoking substitute device may be configured to transition from use mode to standby mode if certain operating conditions are met, for example if it is determined that the battery level in the device is running too low to operate both the auxiliary component and the heating device within the consumable.
  • the smoking substitute device may be configured so that, if it is detected that a consumable is received within the coupling portion of the body of the device, it can transition from use mode to standby mode, if no inhalations have been detected for a predetermined amount of time, but that it should not transition from use mode or standby mode to shipping mode unless it is detected that there is also no consumable received in the coupling portion of the body of the device.
  • the device may be configured so that it requires no inhalations to have been detected for a first predetermined amount of time and no consumable to be received in the coupling portion of the body of the device for a second predetermined amount of time (wherein the first and second predetermined amounts of time may be different), before it is allowed to transition from standby mode or use mode (or any other active sub-mode) to shipping mode.
  • the device can save power by restricting power to the consumable (and to its heating device) when the device is not being actively used for smoking substitute action, but it can maintain operation of the auxiliary component(s), for example for telemetry or for position/orientation sensing, whilst there is a consumable inserted in the device, since this may be taken as an indicator that the user still intends to use the device again in the short to medium term.
  • the device may also provide a grace period during which it is permissible not to have a consumable received in the device - for example when the user is changing his or her consumable - before the device will transition to shipping mode, in which power to the auxiliary component is restricted.
  • the device may be configured so that the transition from an active mode to a shipping mode, and/or the transition from a use active sub-mode to a standby active sub-mode, follows different rules for different respective auxiliary components.
  • the device may be configured so that, when the auxiliary component is a position sensor such as an accelerometer, the device can transition from a use sub-mode to a standby sub-mode if no inhalations have been detected for a pre-determined amount of time, regardless of whether a consumable is currently received in the coupling portion of the device.
  • the device may be configured so that when the auxiliary component is a wireless interface , for example a wireless interface configured to communicate with a wireless interface of a mobile device that has an application running on it for managing the smoking substitute device, the device will not transition from a use sub-mode to a standby sub-mode even if no inhalations have been detected for a pre-determined amount of time, if there is a consumable currently received in the coupling portion of the device.

  • the power source 128 is restricted from supplying power to the auxiliary components.
  • the smoking substitute device in this particular embodiment may thus be configured to entirely prevent power from being supplied to the auxiliary components when the smoking substitute device is in the shipping mode.

  • the shipping mode is operationally efficient and ensures that minimal power is consumed by the device between manufacture and assembly and unpacking by the user. It also provides a safety feature, for example by preventing overheating of the smoking substitute device, which might otherwise occur if it had several electrical components operating within a confined package, before purchase.
  • a smoking substitute device may have to be operated, at least briefly, in an active mode or in a mode that simulates an active mode, for it to be properly tested before it enters shipping mode for transportation.
  • a smoking substitute device may be pre-configured, during the manufacture process, to have a separate "initial testing" mode (in addition to the active mode and shipping mode), which allows the components to be at least briefly activated for testing.
  • the product manufacturer or tester can activate the initial testing mode for testing and provide a pre-determined instruction or set of conditions, in order for the device to then transition to shipping mode, after testing.
  • the smoking substitute device does not have a separate initial testing mode but it is pre-configured so that the manufacturer or tester can briefly operate the device in an active mode, or in a mode that simulates an active mode, for testing.
  • the smoking substitute device will then transition to shipping mode for transportation, if there is no airflow detected for a predetermined period of time.
  • the device may automatically transition to the shipping mode, once the predetermined period of time has passed, after testing is complete.
  • the predetermined period of time applied in this situation, for transitioning the device to shipping mode after testing, can be relatively brief.
  • the transition from the initial testing mode to shipping mode may also have a requirement that the smoking substitute device should not have a consumable received in the coupling portion. It is known that smoking substitute devices are typically not packaged or sold with consumables received therein. Consumables and smoking substitute devices are typically sold separately.
  • the smoking substitute device is configured so that the user must ensure that two conditions are met, in order to transition the smoking substitute device from the shipping mode to the active mode.
  • the two conditions are:
  • the user in order to transition the smoking substitute device from the shipping mode to the active mode, is to correctly insert a suitable consumable 150 into the smoking substitute device, so that it couples mechanically and electrically with the coupling portion 121, and to perform an inhalation through the smoking substitute device, via the mouthpiece 166 of the inserted consumable 150. Therefore, advantageously, the user can switch the smoking substitute device to the active mode - which means that power will be supplied to is auxiliary components - without requiring the actuation of (or even the presence in the device of) a separate dedicated user input component, for example an on/off button or switch.
  • the smoking substitute device 162 of the consumable 150 following the steps to transition the smoking substitute device to operating in the active mode will also enable the supply of power to the heating device 162 of the consumable 150, via the coupled electrical interfaces 136, 160 of the smoking substitute device and of the consumable 150.
  • a separate routine may be required in order to initiate the supply of power to the heating device 162 of the consumable 150, for the first time.
  • the subsequent operation of the heating device 162 when the smoking substitute device is in the active mode can be controlled as described in detail above, based on detection signals issued by the airflow sensor 131, when a user inhales through the smoking substitute device.
  • the method for controlling the operation of the heating device 162 when the smoking substitute device is in the active mode is further refined, because the active mode has two sub-modes.
  • Other embodiments may not have any sub-modes, and still others may have more than two sub-modes.
  • Other embodiments may also have sub-modes within the shipping mode, but this particular embodiment does not.
  • the first sub-mode may be referred to as a so-called "use mode". It is a sub-mode of the active mode in which the control unit 130 of the smoking substitute device permits power to be supplied to the consumable 150. Notably, if the smoking substitute device is in "use mode", power can be supplied to the heating device 162 in the consumable 150, to enable liquid or tobacco to be heated for smoking substitute action. Power need not be continually supplied to the heating device 162 when the smoking substitute device is in the use mode. Instead, the times at which power will be supplied to the heating device 162 will still be controlled according to the detection signals received from the airflow sensor 131, indicating user inhale actions.
  • the smoking substitute device will default to being in the use mode (or sub-mode) when the device transitions from operating in a shipping mode to operating in an active mode, unless certain pre-set operating conditions determine that it cannot be in use mode. This will be understood further from the description of the second sub-mode, below.
  • the second sub-mode of the active mode which may be referred to as a so-called "standby mode" is a sub-mode in which power is supplied to the auxiliary components, but not to the consumable 150.
  • the smoking substitute device therefore does not enable liquid or tobacco in the consumable 150 to be heated for smoking substitute action, when it is in standby mode.
  • the smoking substitute device will only enter standby mode if, when the device transitions from operating in a shipping mode to operating in an active mode, there is insufficient power (i.e. insufficient battery level) to operate both the auxiliary components and the heating device 162 within the consumable 150.
  • the standby mode therefore enables the auxiliary components to continue to operate, and carry out their important functions as detailed above, but prevents smoking substitute action.
  • the smoking substitute device During subsequent operation of the smoking substitute device, once it has sufficient power (and if the conditions for transitioning back to shipping mode, as detailed below, have not been met) the smoking substitute device will default to being in active mode, in which supplying power to the heating device is permissible, in accordance with the control signals based on the detected airflows within the smoking substitute device.
  • the "use” sub-mode refers to the operating mode of the smoking substitute device when it is actively supplying power to the heating device for smoking substitute action. Therefore, the device would be operating in “use mode” when the user is inhaling on the smoking substitute device.
  • the "standby” sub-mode refers to the operating mode of the smoking substitute device when it has transitioned out of shipping mode, but it is not currently actively supplying power to the heating device for smoking substitute action. Therefore, the device would be operating in "standby mode” in between inhalation actions, if the conditions are not met for it to transition back to shipping mode.
  • a smoking substitute device may not be possible for a smoking substitute device to automatically transition back to being in shipping mode. It may instead require a dedicated user input, either directly made at the smoking substitute device or made via a connected mobile device or application.
  • the smoking substitute device is configured so that it can transition back to shipping mode automatically, if certain conditions are met.
  • the smoking substitute device is configured to transition back to operating in shipping mode if no further inhale actions are detected during a pre-determined period of time following the most recent inhale action.
  • That pre-determined period of time may be relatively long. For example, it may be of the order of a few days or even a few weeks.
  • the transition can be controlled by the control unit, which is configured to make determinations based on signals received from the air flow sensor and the electrical interface within the coupling portion, and to issue control instructions accordingly.
  • the present inventor(s) recognise that it is likely to be inconvenient to the user if the smoking substitute device transitions back to shipping mode too readily, because operation of the auxiliary components that the user finds useful is disabled when the device is in shipping mode.
  • the present inventors have further recognised that this potential inconvenience should be balanced against the inconvenience and inefficiency disadvantages of continually operating the auxiliary components if the smoking substitute device is going unused by the user for smoking substitute action for extended periods of time.
  • the length of the pre-determined period of time, after which the smoking substitute device will transition back to being in shipping mode if no inhale actions are detected will be different dependent on whether or not the device has a consumable inserted therein. If the smoking substitute device has a consumable inserted therein, which is detectable via the electrical interfaces of the smoking substitute device and consumable as detailed above, the control unit in this refinement of the present embodiment may be configured to interpret the presence of that consumable as an indication that the user is likely to want to use the device for smoking substitute action again in the short to medium term. The microprocessor will therefore be configured only to transition the device back to shipping mode if no inhalation actions are detected for a relatively long first period of time.
  • the microprocessor will be configured to interpret this as an indication that the user may not want to use the device for smoking substitute action again in the short to medium term and therefore it will be configured to transition the device back to shipping mode if no inhalation actions are detected for second period of time, that is shorter than the aforementioned first period of time.
