Definitions

  • the present invention relates to an aerosol-generating system with a device having a sealed housing compartment.
  • the present invention also relates to a method for operating an aerosol-generating system and a use of a venting membrane in an aerosol-generating device.
  • aerosol-generating system is an electrically operated smoking system.
  • Known handheld electrically operated smoking systems typically comprise an aerosol-generating device comprising a battery, control electronics and an electric heater for heating an aerosol-generating article designed specifically for use with the aerosol-generating device.
  • the aerosol-generating article comprises an aerosol-forming substrate, such as a tobacco rod or a tobacco plug, and the heater contained within the aerosol-generating device is inserted into or located around the aerosol-forming substrate when the aerosol-generating article is inserted into the aerosol-generating device.
  • the aerosol-generating article may comprise a capsule containing an aerosol-forming substrate, such as loose tobacco.
  • an aerosol-generating device comprising a heating chamber adapted to receive an aerosol-generating article, a heating element, a sealed housing compartment, and a venting means adapted to allow gas flow from the sealed housing compartment to the outside of the aerosol-generating device to compensate for heat expansion of gas inside the housing compartment due to heating operation of the heating element.
  • the transverse direction of the aerosol-generating device may be perpendicular to a longitudinal direction of the aerosol-generating device.
  • the longitudinal direction may be the main extension direction of the aerosol-generating device, namely the direction in which the aerosol-generating device has its greatest length.
  • the longitudinal direction is the height direction and the transversal direction may be a horizontal direction.
  • the transversal direction may be perpendicular to a width direction of the aerosol-generating device. Any indications in the following regarding "upper” and "lower” are with respect to the longitudinal direction being the height direction.
  • An aerosol-generating article may be inserted in the heating chamber of the aerosol-generating device in the longitudinal direction, such that the aerosol-generating article is at least partially arranged in a heating chamber.
  • a mouth-end portion of the aerosol-generating article may protrude from the heating chamber in the longitudinal direction.
  • the housing compartment is sealed to prevent the ingress of dust or ingress of dust and water.
  • the housing compartment may comprise a bottom plate. The bottom plate may sealingly close the lower side of the housing compartment. At least one of the heating element, control electronics and a battery are arranged in the housing compartment.
  • the heating element may be provided in or adjacent to the sealed housing compartment.
  • the heating element may be an electrical resistance heating element, or an inductive heating element, such as an inductor, for example a coil.
  • Control electronics may be provided, which are adapted to control the heating element to swiftly heat the aerosol-generating article in the heating chamber.
  • the heating element and the control electronics of the device may be adapted, such that the temperature of the heating element is in between 70 degrees Celsius and 130 degrees Celsius, or in between 80 degrees Celsius and 120 degrees Celsius, or in between 80 degrees Celsius and 100 degrees Celsius.
  • the heating element and the control electronics may be adapted, such that the heating time for heating the heating element from ambient temperature to at least 80 degrees Celsius is less than 5 seconds or less than 3 seconds.
  • the heating element and the control electronics of the device may be adapted, such that the aerosol-generating article is heated to a temperature between 70 degrees Celsius and 130 degrees Celsius, or in between 80 degrees Celsius and 120 degrees Celsius, or in between 80 degrees Celsius and 100 degrees Celsius.
  • the heating element and the control electronics may be adapted, such that the heating time for heating the aerosol-generating article from ambient temperature to at least 80 degrees Celsius is less than 5 seconds or less than 3 seconds.
  • the heating element and the control electronics of the device may be adapted, such that the aerosol-generating article is heated to a temperature between 250 degrees Celsius and 400 degrees Celsius, or in between 300 degrees Celsius and 350 degrees Celsius.
  • the heating element and the control electronics may be adapted, such that the heating time for the aerosol-generating article from ambient temperature to at least 300 degrees Celsius is less than 60 seconds or less than 30 seconds.
  • the heating element and the control electronics may be adapted to heat in several consecutive heating cycles during the consumption of one aerosol-generating article, with a temperature variation in the heating element of at least 10 degrees Celsius, or at least 20 degrees Celsius.
  • venting means allows gas to flow from the sealed housing compartment to the outside to prevent excess pressures in the sealed housing compartment.
  • the venting means may be adapted to allow gas to flow from the outside into the sealed housing compartment, to compensate negative, below-ambient pressures during cooling or in the low temperature phases during aerosol generation.
  • the venting means may be permeable for gases and impermeable for water.
  • the aerosol-generating device may be waterproof.
  • the venting means may have a water entry pressure of at least 5 Kilopascal, preferably of at least 10 Kilopascal, in particular of about 12 Kilopascal. This enables, that the device is increasingly waterproof.
