Definitions

  • the present invention relates to a smoking substitute device and particularly, although not exclusively, to the management of user generated data when the smoking substitute device is connected to an external device.
  • 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.
  • 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.
  • the smoking substitute device does not operate in isolation to other devices, it would be advantageous to provide the user with control over user generated data whilst maintaining the advantageous features associated with recording and logging the user generated data.

  • the button 138 is arranged to be activated from an exterior of the smoking substitute device.
  • the button is activated by pressing as is known in the art.
  • the button 138 may have another operational purpose in which case the firmware is configured to differentiate between an input to trigger said other operational purpose and a reset operation input by a variance in the press condition, frequency, press pattern or the like. For instance, a short press where the button 138 is pressed for less than a second may determine an input operation, whereas a long press may determine a reset operation.
  • the long press may be determined as a press and hold of the button for more than two seconds or more than 3 seconds.
  • the additional component may be an accelerometer arranged to monitor taps of the smoking substitute device's body.
  • the accelerometer is arranged to determine other operational commands the firmware is configured to differentiate between commands by identifying specific tap or tap pattern characteristics.
  • the specific push or tap or other input characteristic or pattern is selected to be complex to reduce the pattern being replicated from manipulations during general use or whilst stowed.
  • the actuator may be arranged to be concealed or protected or difficult to access in order to reduce any unintended activations.
  • the body 120 also houses memory 132.
  • the memory as described above is arranged to store firmware data that is used by a control unit 130 to perform the operational functions of the smoking substitute device as is known in the art.

It will be appreciated that Steps S100, S110 and S120 may be repeated multiple times, periodically and/or at varying intervals as required by the use of the smoking substitute device.
  • Step S140 the control unit identifies the reset operation and deletes user data stored in the memory.
  • the control unit can recognise the reset operation as either a predetermined manipulation of the additional component or receipt by the communication interface of a reset command from the external device. That is, either through a hardware triggered reset or a software triggered reset.
  • the hardware triggered reset requires a specific manipulation of the smoking substitute device by the user.
  • the management method includes the step of the user pressing the button to replicate the push time or push pattern predetermined as a reset operation input.
  • the software triggered reset requires the user to complete a step of triggering the reset command to be transmitted to and received by the communication interface of the smoking substitute device. For instance, the user activates the reset command through the application operating on the external device. It will be appreciated that when using a wireless communication connection, prior to step S120, the user may complete a pairing or authorisation step so that the external device is trusted by the smoking substitute device.
  • Figure 6 shows a further exemplary method embodiment, wherein the step S110 of storing user data in the memory further includes the step S112 of first identifying the user data as either user specific data or global device data.
  • the controller stores both categories of user data in the memory.
  • the controller may be configured to store the user specific data in a separate area to the global device data.
  • the memory may be organised so that the user specific data is overwritten when the memory becomes full on a first-in-first-out basis.
  • step S112 of identifying the category of user data the controller may determine global device data as user data that is logged apportioned over the lifetime of operational use of the smoking substitute device. This global device data is not overwritten or deleted as part of a reset operation.
  • the controller may identify user specific data as user data that is logged over apportioned over a period of time since the last reset operation or, if no previous reset operation has occurred, since the start of operation of the smoking substitute device.
  • Step S140 of deleting user data from the memory comprises deleting user specific data.
  • the user data identified as global device data is not deleted. Consequently, a subsequent connected device can still access lifetime data from the memory of the smoking substitute device in order to provide useful information or feedback or predictive analysis on the device's operational performance.
