Definitions

  • the present invention relates to a smoking substitute system and particularly, although not exclusively, to a smoking substitute system comprising a smoking substitute device and an aerosolforming article.
  • 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.
  • Smoking substitute systems include 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.
  • 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 closure member comprises least one of a door and a ring each movable relative to the housing.
  • the door is configured to slide relative to the housing for blocking the one or more of the plurality of openings, e.g. when the door is moved to the partially opened position.
  • the door may be any suitable slideable member such as a slideable gate that is arranged to toggle and be retainable at one or more partially opened positions to block one or more or the openings.
  • such mechanism may allow the closure member to move and be retained in a predetermined position such that a consistent airflow may be consistently achieved with every puff.
  • the device further comprises a cap configured to engage with the housing, wherein the cap is movable relative to the housing so as to block the one or more of the plurality of openings.
  • the cap may move along and be retainable at different locations along the axial direction of the housing and thereby a portion of the cap may be configured to block the one or more of the openings at said different locations within the range of movement.
  • the cap may be slideable, relative to the housing, between an open position and closed positon, wherein said different locations may be locations between the closed position and the open position.
  • such mechanism does not required additional movable parts to be included in the device.
  • the device may comprise a housing in the form of an elongate body.
  • An end of the housing may be configured for engagement with an aerosol-forming article.
  • the housing may be configured for engagement with a heated tobacco (HT) consumable (or heat-not-burn (HNB) consumable).
  • HT heated tobacco
  • HNB heat-not-burn
  • the housing may be defined with an air inlet comprising a plurality of openings to facilitate airflow entering into the housing.
  • the housing may comprise a closure member to block or close one or more of the plurality of openings, to vary quantity of airflow entering into the housing.
  • the heating element of the tube heater may surround at least a portion of the cavity.
  • the heating element may surround a portion of the aerosol-forming article (i.e. so as to heat that portion of the aerosol-forming article).
  • the heating element may surround an aerosol forming substrate of the aerosol-forming article. That is, when an aerosol-forming article is engaged with the device, the aerosol forming substrate of the aerosol-forming article may be located adjacent an inner surface of the (tubular) heating element. When the heating element is activated, heat may be transferred radially inwardly from the inner surface of the heating element to heat the aerosol forming substrate.
  • the device may comprise an input connection (e.g. a USB port, Micro USB port, USB-C port, etc.).
  • the input connection may be configured for connection to an external source of electrical power, such as a mains electrical supply outlet.
  • the input connection may, in some cases, be used as a substitute for an internal power source (e.g. battery or rechargeable battery). That is, the input connection may be electrically connectable to the heater (for providing power to the heater).
  • the input connection may form at least part of the power source of the device.
  • the controller may be configured to control the operation of the heater (and e.g. the heating element).
  • the controller may be configured to control vaporisation of an aerosol forming part of an aerosol-forming article engaged with the device.
  • the controller may be configured to control the voltage applied by power source to the heater.
  • the controller may be configured to toggle between applying a full output voltage (of the power source) to the heater and applying no voltage to the heater.
  • the control unit may implement a more complex heater control protocol.
  • the external device may be a mobile device.
  • the external device may be a smart phone, tablet, smart watch, or smart car.
  • An application e.g. app
  • the application may facilitate communication between the device and the external device via the wired or wireless connection.
  • the device 201 includes a controller (not shown) located in the electronics cavity 224.
  • the controller comprises a microcontroller mounted on a printed circuit board (PCB).
  • PCB printed circuit board
  • the USB port 206 is also connected to the controller 208 (i.e. connected to the PCB and microcontroller).
