Definitions

  • the device comprises a body and a cap engageable with the body.
  • the device also comprises a heating element extending from the body.
  • the cap is biased into the engaged position, biased into the disengaged position, or both.
  • the device may comprise biasing means which bias the cap into the engaged position, biased into the disengaged position, or both.
  • the biasing means comprise one or more magnets.
  • the cap comprises one or more magnets.
  • the body comprises one or more magnets.
  • the cap and the body each respectively comprise one or more magnets.
  • the cap is biased into the engaged position. In this way, the cap will “snap” back into the engaged position once the user no longer requires the cap to be disengaged, simply by the user releasing the cap.
  • a heat-not-burn device comprising a cap movable between an engaged position to conceal a heating element and a disengaged position to expose the heating element.
  • the heat-not-burn device is configured to enable a power supply to the heating element when the cap is detected to be in the engaged position, and disable said power supply when the cap is detected to be in the disengaged position.
  • the heating element may be formed of ceramic.
  • the heating element may comprise a core (e.g. a ceramic core) comprising Al 2 O 3 .
  • the core of the heating element may have a diameter of 1.8 mm to 2.1 mm, e.g. between 1.9 mm and 2 mm.
  • the heating element may comprise an outer layer (e.g. an outer ceramic layer) comprising Al 2 O 3 .
  • the thickness of the outer layer may be between 160 ⁇ m and 220 ⁇ m, e.g. between 170 ⁇ m and 190 ⁇ m, e.g. around 180 ⁇ m.
  • the heating element may comprise a heating track, which may extend longitudinally along the heating element.
  • the heating track may be sandwiched between the outer layer and the core of the heating element.
  • the heating track may comprise tungsten and/or rhenium.
  • the heating track may have a thickness of around 20 ⁇ m.
  • the heating element may be located in the cavity (of the device), and may extend (e.g. along a longitudinal axis) from an internal base of the cavity towards an opening of the cavity.
  • the length of the heating element i.e. along the longitudinal axis of the heater
  • the heating element may be less than the depth of the cavity.
  • the heating element may extend for only a portion of the length of the cavity. That is, the heating element may not extend through (or beyond) the opening of the cavity.
  • 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 cap may be configured such that when an aerosol-forming article is engaged with the device (e.g. received in the cavity), only a portion of the aerosol-forming article is received in the cavity. That is, a portion of the aerosol-forming article (not received in the cavity) may protrude from (i.e. extend beyond) the opening.
  • This (protruding) portion of the aerosol-forming article may be a terminal (e.g. mouth) end of the aerosol-forming article, which may be received in a user's mouth for the purpose of inhaling aerosol formed by the device.
  • the aerosol-forming substrate may comprise plant material.
  • the plant material may comprise least one plant material selected from the list including Amaranthus dubius, Arctostaphylos uva-ursi (Bearberry), Argemone mexicana, Amica, Artemisia vulgaris, Yellow Tees, Galea zacatechichi, Canavalia maritima (Baybean), Cecropia mexicana (Guamura), Cestrum noctumum, Cynoglossum virginianum (wild comfrey), Cytisus scoparius, Damiana, Entada rheedii, Eschscholzia califomica (California Poppy), Fittonia albivenis, Hippobroma longiflora, Humulus japonica (Japanese Hops), Humulus lupulus (Hops), Lactuca virosa (Lettuce Opium), Laggera alata, Leonotis
  • the flavourant may be provided in solid or liquid form. It may include menthol, liquorice, chocolate, fruit flavour (including e.g. citrus, cherry etc.), vanilla, spice (e.g. ginger, cinnamon) and tobacco flavour.
  • the flavourant may be evenly dispersed throughout the aerosol-forming substrate or may be provided in isolated locations and/or varying concentrations throughout the aerosol-forming substrate.
  • FIG 1A is a schematic providing a general overview of a smoking substitute system 100.
  • the system 100 includes a substitute smoking device 101 and an aerosol-forming article in the form of a consumable 102, which comprises an aerosol former 103.
  • the system is configured to vaporise the aerosol former by heating the aerosol former 103 (so as to form a vapour/aerosol for inhalation by a user).
  • the heater 104 forms part of the consumable 102 and is configured to heat the aerosol former 103.
  • the heater 104 is electrically connectable to the power source 105, for example, when the consumable 102 is engaged with the device 101. Heat from the heater 104 vaporises the aerosol former 103 to produce a vapour. The vapour subsequently condenses to form an aerosol, which is ultimately inhaled by the user.
  • the system 100 may also comprise a voltage regulator to regulate the output voltage from the power source 105 to form a regulated voltage.
  • the regulated voltage may then be applied to the heater 104.
  • the controller 108 is operatively connected to the UI 107.
  • the controller 108 may receive an input signal from the input means of the UI 107.
  • the controller 108 may transmit output signals to the UI 107.
  • the output means of the UI 107 may convey information, based on the output signals, to a user.
  • the controller also comprises a memory 109, which is a non-volatile memory.
  • the memory 109 includes instructions, which, when implemented, cause the controller to perform certain tasks or steps of a method.
  • the device 201 and the consumable 202 are configured such that the consumable 202 can be engaged with the device 201.
  • Figure 2A shows the device 201 and the consumable 202 in an engaged state
  • Figure 2B shows the device 201 and the consumable 202 in a disengaged state.
  • the device 201 comprises a body 209 and cap 210.
  • the cap 210 is engaged at an end of the body 209.
  • the cap 210 is moveable relative to the body 209, as best seen in Figures 2F and 2G .
  • the cap 210 is slideable and can slide along a longitudinal axis of the body 209.
  • the cap 210 is movable between an engaged position and a disengaged position.
  • Figure 2F is a front view of the device 201 with the cap 210 in an engaged position.
  • Figure 2G is a front perspective view of the device 201 with the cap 210 in a disengaged position.
  • the aerosol-forming substrate 213 is substantially cylindrical and is located at an upstream end 217 of the consumable 202, and comprises the aerosol former of the system 200.
  • the aerosol forming substrate 213 is configured to be heated by the device 201 to release a vapour.
  • the released vapour is subsequently entrained in an airflow flowing through the aerosol-forming substrate 213.
  • the airflow is produced by the action of the user drawing on a downstream 218 (i.e. terminal or mouth) end of the consumable 202.
  • the aerosol-forming substrate 213, upstream filter 215 and spacer 216 are circumscribed by a paper wrapping layer.
  • the terminal filter 214 is circumscribed by a tipping layer that also circumscribes a portion of the paper wrapping layer (so as to connect the terminal filter 214 to the remaining components of the consumable 202).
  • the upstream filter 215 and terminal filter 214 are circumscribed by further wrapping layers in the form of plug wraps.
  • Figure 2E shows a cross section through a central longitudinal plane through the device 201.
  • the device 201 is shown with the consumable 202 engaged therewith.
  • the heating element 223 of the heater 204 projects from an internal base of the cavity 222 along a longitudinal axis towards the opening 221. As is apparent from the figure, the length (i.e. along the longitudinal axis) of the heating element is less than a depth of the cavity 222. In this way, the heating element 223 does not protrude from or extend beyond the opening 221.
  • the device 201 comprises a further input means (i.e. in addition to the button 212) in the form of a puff sensor 225.
  • the puff sensor 225 is configured to detect a user drawing (i.e. inhaling) at the downstream end 218 of the consumable 202.
  • the puff sensor 225 may, for example, be in the form of a pressure sensor, flowmeter or a microphone.
  • the puff sensor 225 is operatively connected to the controller 208 in the electronics cavity 224, such that a signal from the puff sensor 225, indicative of a puff state (i.e. drawing or not drawing), forms an input to the controller 208 (and can thus be responded to by the controller 208).
