Definitions

  • the smoking substitute apparatus may be in the form of a consumable.
  • the consumable may be configured for engagement with a main body (i.e. so as to form a closed substitute smoking system).
  • the consumable may comprise components of the system that are disposable, and the main body may comprise non-disposable or non consumable components (e.g. power supply, controller, sensor, etc.) that facilitate the delivery of aerosol by the consumable.
  • an aerosol former e.g. e-liquid
  • e-liquid may be replenished by replacing a used consumable with an unused consumable.
  • airflow between the mouthpiece and the flavour delivery portion may be permitted.
  • the flow diverter may divert airflow received from the mouthpiece to the second passage (i.e. and past the flavour delivery portion).
  • the flow diverter may comprise an actuator configured to move the flow diverter between the first and second positions.
  • the actuator may be configured to move the flow diverter between the first and second positions in response to a control signal from a controller (e.g. comprising a microprocessor).
  • the actuator may be configured to move the flow diverter from the first position to the second position in response to an exhalation into the mouthpiece.
  • the actuator may be configured to move the flow diverter from the second position to the first position in response to an inhalation from the mouthpiece.
  • the actuator may be configured to move the flow diverter in response to the detection (e.g. by a sensor) of an inhalation or exhalation at the mouthpiece.
  • the controller (which may form part of the smoking substitute apparatus or a main body engaged with the smoking substitute apparatus) may be configured to control the supply of power from the power source to the heater of the smoking substitute apparatus (e.g. via the electrical contacts).
  • a memory may be provided and may be operatively connected to the controller.
  • the memory may include non-volatile memory.
  • the memory may include instructions which, when implemented, cause the controller to perform certain tasks or steps of a method.
  • the system 101 is configured to vaporise an aerosol-former, which in the illustrated embodiment, is in the form of a nicotine-based e-liquid 104.
  • the e-liquid 104 comprises nicotine and a base liquid including propylene glycol and/or vegetable glycerine.
  • the e-liquid 104 is flavourless (and does not include any added flavourant). That is, if the e-liquid 104 were to be inhaled (i.e. in aerosol form) by a user, it would not have a particularly perceptible flavour or taste.
  • this e-liquid 104 is stored within a reservoir in the form of a tank 105 that forms part of the consumable 103.
  • the consumable 103 is a "single-use" consumable 103. That is, upon exhausting the e-liquid 104 in the tank 105, the intention is that the user disposes of the entire consumable 103.
  • the e-liquid i.e. aerosol former
  • the tank may be refillable with e-liquid or the e-liquid may be stored in a non-consumable component of the system.
  • the e-liquid may be stored in a tank located in the device or stored in another component that is itself not single-use (e.g. a refillable cartomizer).
  • the first passage 106 may be at least partly defined by a tube (e.g. a metal tube) extending through the consumable 103.
  • e-liquid 104 contained in the tank 105 is conveyed from the opposing ends of the porous wick 110 to a central portion of the porous wick 110 so as to be exposed to the airflow in the first passage 106 (i.e. caused by a user inhaling).
  • the helical filament 111 is wound about this exposed central portion of the porous wick 110 and is electrically connected to an electrical interface in the form of electrical contacts 112 mounted at the end of the consumable that is proximate the main body 102 (when engaged).
  • the electrical contacts 112 contact corresponding electrical contacts (not shown) of the main body 102.
  • the main body electrical contacts are electrically connected to a power source (not shown) of the main body 102, such that (in the engaged position) the filament 111 is electrically connected to the power source. In this way, power can be supplied by the main body 102 to the filament 111 in order to heat the filament 111.
  • This heat is transferred from the filament 111 to the porous wick 110 which causes e-liquid 104 conveyed by the porous wick 110 to increase in temperature to a point at which it vaporises.
  • the vaporised e-liquid becomes entrained in the airflow and, between the vaporisation point at the filament 111 and the mouthpiece opening 108 of the first passage 106, condenses to form an aerosol.
  • This aerosol is then inhaled, via the mouthpiece 109, by a user of the system 101.
  • the power source of the main body 102 may be in the form of a battery (e.g. a rechargeable battery).
  • the main body 102 may comprise a connector in the form of e.g. a USB port for recharging this battery.
  • the main body 102 may also comprise a controller that controls supply of power from the power source to the main body electrical contacts (and thus to the filament 111). That, is the controller may be configured to control a voltage applied across the main body electrical contacts, and thus the voltage applied across the filament 111. In this way, the filament 111 may only be heated under certain conditions (e.g. during a puff and/or only when the system is in an active state).
  • the main body 102 may include a puff sensor (not shown) that is configured to detect a puff (i.e. inhalation).
  • the puff sensor may be operatively connected to the controller so as to be able to provide a signal, to the controller, which is indicative of a puff state (i.e. puffing or not puffing).
  • 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 or may be provided in isolated locations and/or varying concentrations.
  • the first 106 and second 113 passages are arranged such that upon inhalation from the mouthpiece 109 (i.e. through the mouthpiece opening 108) airflows past the wick 110 to the mouthpiece opening 108. Further, upon exhalation into the mouthpiece opening 108 air flows from the mouthpiece 109 and past the flavour delivery portion 114. In this way, flavourant of the flavour delivery portion 114 may be entrained in the air flowing past the flavour delivery portion 114. This flavoured airflow may then be discharged from the outlet 115 of the second passage 113 towards a user's nasal cavity. Thus, exhalation by a user leads to the user smelling the flavoured (or scented) air. If an exhalation is performed prior to an inhalation, the flavour or aroma of the flavoured air may be smelled by a user prior to and during the inhalation. This may alter a user's overall experience during the inhalation.
  • the illustrated embodiment comprises a flow diverter 118.
  • the flow diverter is movable between a first position (shown in Figure 1C ) and a second position (shown in Figure 1D ).
  • first position airflow from the wick 110 to the mouthpiece 109 is permitted (i.e. such that air can be inhaled through the mouthpiece opening 108 by a user), whilst airflow from the mouthpiece 109 to the flavour delivery portion 114 is prevented.
  • the second position airflow between the wick 110 and the mouthpiece 109 is prevented, whilst airflow from the mouthpiece 109 to the flavour delivery portion 114 is permitted.
  • the flow diverter 118 is hingably mounted to a wall of the first passage 106 at the side of the second passage inlet 117 that is closer to the wick 110. In this way, in the first position the flow diverter 118 extends from its hingable mounting towards the mouthpiece opening 108 so as to extend across (and obstruct) the second passage inlet 117. In the second position, the flow diverter 118 extends diagonally across the first passage 106 so as to obstruct the first passage 106. The angle of the flow diverter 118 with respect to the longitudinal axis of the first passage 106 facilitates flow of air from the first passage 106 into the second passage 113 (through the second passage inlet 117). Whilst not shown, the flow diverter 118 may be biased to the first or second position.
  • the flow diverter 118 may be configured to be moved between the first and second positions by exhalation and/or inhalation (i.e. by a user) at the mouthpiece.
  • the flow diverter 118 may be configured to be moved from the first position to the second position by exhalation into the mouthpiece opening 108 of the mouthpiece 109 and/or may be configured to be moved from the second position to the first position by an inhalation from the mouthpiece 109.
  • the flow diverter 118 may alternatively or additionally comprise an actuator configured to move the flow diverter 118 between the first and second positions.
  • the actuator may be configured to move the flow diverter 118 between the first and second positions in response to a control signal from the controller.
  • the actuator may be configured to move the flow diverter 118 in response to the detection (e.g. by a sensor) of an inhalation or exhalation at the mouthpiece.
  • the main body 102 and consumable 103 may comprise a further interface which may, for example, be in the form of an RFID reader, a barcode or QR code reader.
  • This interface may be able to identify a characteristic (e.g. a type) of a consumable 103 engaged with the main body 102.
  • the consumable 103 may include any one or more of an RFID chip, a barcode or QR code, or memory within which is an identifier and which can be interrogated via the interface.
  • the interface may allow the detection of the flavour associated with the flavour delivery portion 114.
  • the controller may control e.g. the power supply in response to the detected flavour.
