Definitions

  • the present specification relates to a cleaning consumable for cleaning an aerosol- generating device having a heating element, to a method of cleaning an aerosol-generating device, and to an aerosol-generating system comprising an aerosol-generating device and a cleaning consumable.
  • Aerosol-generating articles in which an aerosol-forming substrate for generating an inhalable aerosol is heated, rather than combusted, are known in the art.
  • the aim of such heated aerosol-generating articles is to reduce known harmful smoke constituents produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes.
  • an aerosol is generated by the transfer of heat from a heat source to a physically separate aerosol-forming substrate or material, which may be located within, around or downstream of the heat source.
  • volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and entrained in air drawn through the smoking article. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
  • WO2013102614 discloses an example of an aerosol-generating device in which an aerosol-forming substrate of an aerosol-generating article is heated in direct contact with a heating element to form an inhalable aerosol.
  • heat from a heating element may be conveyed almost instantaneously to at least a portion of the aerosol-forming substrate when the heating element is actuated, and this may facilitate the rapid generation of an aerosol.
  • the overall heating energy required to generate an aerosol may be lower than would be the case in a system where the aerosol-forming substrate does not directly contact a heating element and initial heating of the substrate occurs by convection or radiation. Where a heating element is in direct contact with an aerosol-forming substrate, the initial heating of portions of the substrate that are in contact with the heating element will be effected by conduction.
  • an aerosol-forming substrate such as a tobacco substrate
  • volatile compounds When an aerosol-forming substrate, such as a tobacco substrate, is heated, volatile compounds are released. Volatile compounds and aerosol evolved by the heat from the heating element may become deposited on the aerosol-generating device and in particular on a surface of the heating element. Particles of the aerosol-forming substrate itself may also become adhered to the heating element, particularly if the heating element is in direct contact with the aerosol-forming substrate.
  • a heating blade warms a tobacco substrate to temperatures in excess of 200°C, releasing volatile compounds, nicotine and glycerol, all of which form a respiratory aerosol for inhalation by the consumer.
  • residues and dust tend to collect inside the device after smoking multiple aerosol-generating articles, which means that periodic cleaning of the device and the heating-blade is required.
  • Particles and compounds adhered to and deposited on the heating element of an aerosol-generating device may prevent the heating element from functioning in an optimal manner. These particles and compounds may also break down during use of the aerosol-generating device and impart unpleasant or bitter flavours to a user. For these reasons it is desirable to clean the heating element periodically.
  • Cleaning may be effected by a pyrolysis method, in which the heating element is heated to a temperature sufficiently high to burn any residues or deposits. Pyrolysis on its own may not always be effective, however. A brush or scraper may be used as an alternative to, or in addition to, pyrolysis. However, it may be a delicate operation to physically clean the heating element of an aerosol-generating device without damaging the heating element.
  • a cleaning consumable may be provided for cleaning a heating element of an aerosol-generating device.
  • the cleaning consumable comprises a solvent-evolving substrate capable of releasing a cleaning solvent when heated by the heating element.
  • the cleaning solvent is released into contact with the heating element.
  • the cleaning consumable is dimensioned to engage with the aerosol-generating device such that the heating element can heat the solvent-evolving substrate to evolve the cleaning solvent.
  • the cleaning consumable is dimensioned, at least in part, substantially identically to an engageable portion of an aerosol-generating article for generating an inhalable aerosol when heated by the aerosol-generating device.
  • the solvent-evolving substrate is configured to be penetrated by the heating element of the aerosol-generating device and the solvent-evolving substrate is encapsulated or sealed to prevent egress of the cleaning solvent until the cleaning consumable is engaged with the aerosol-generating device.
  • the cleaning consumable is rod-shaped and resembles a cigarette.
  • the solvent-evolving substrate is configured to be penetrated by the heating element of the aerosol-generating device.
  • the heating element is brought into close proximity to, or contact with, the solvent-evolving substrate prior to the step of heating.
  • the solvent that is evolved when the solvent-evolving substrate is heated then contacts the heating element and can act to dissolve or loosen unwanted residues and deposits on the heating element.
  • the cleaning solvent acts to at least partially dissolve or chemically alter one or more residue or deposit left on the aerosol-generating device by the heating of an aerosol-generating article.
  • the cleaning solvent is a solvent that acts to at least partially dissolve or chemically alter one or more residue or deposit left by the heating of a tobacco based substrate of an aerosol generating article.
  • the cleaning solvent is preferably sufficiently volatile that it swiftly evaporates after removal of the cleaning consumable from the aerosol-generating device.
  • the solvent should not contaminate the aerosol-generating device such that the user can detect an unwanted taste or flavour during consumption of their next aerosol-generating article.
  • the solvent-evolving substrate is encapsulated or sealed to prevent egress of the cleaning solvent until the cleaning consumable is engaged with the aerosol-generating device.
  • the solvent-evolving substrate may be hermetically sealed within a polymeric or foil wrapper such that the cleaning solvent is retained within the substrate.
  • the wrapper may then be pierced on engagement with the aerosol-generating device in order to allow egress of the cleaning solvent from the substrate.
  • a heating element of the aerosol- generating device may be used to pierce a wrapper encapsulating a solvent-evolving substrate, in which case the engagement with the aerosol-generating device may be made simply to cause the heating element to be inserted into the solvent-evolving substrate.
  • the combination of an encapsulated or sealed substrate and the ability of the substrate to be penetrated by the heater allows the use of volatile cleaning solvents, which would evaporate if not encapsulated or sealed, and allows the delivery of those solvents directly to the heater to effect the cleaning.
