Definitions

  • the present invention relates to an aerosol-generating device for use in an aerosol- generating system.
  • the system comprises a primary device for receiving the aerosol- generating device to provide power to the device to charge a power supply such as a battery.
  • Electrically operated smoking systems significantly reduce sidestream smoke, as compared to lit-end smoking devices, while permitting a consumer to selectively activate the smoking system during the smoking experience.
  • Electrically operated smoking systems typically include an aerosol-generating device having a housing for receiving an aerosol-generating article or a smoking article, heating elements to generate an aerosol, a power source and the necessary electronic circuitry.
  • the circuitry may be, for example, circuitry for controlling the heating and charging of the aerosol-generating device. Having a portable device and primary charging device provides the advantage of a small aerosol-generating device being the portable device that is easy to hold and use, but also the ability to quickly and conveniently recharge the aerosol generating device for repeated use.
  • the aerosol-generating device may be inserted incorrectly into the primary, charging, device which may damage the aerosol-generating device or the primary, charging, device.
  • inserting the device incorrectly may result in the device not being charged, providing the user with an unsatisfactory experience.
  • an electrically heated aerosol-generating system comprising a primary device, and a secondary device.
  • the primary device comprises: a power supply; a cavity configured to receive the secondary device; a plurality of electrical contacts within the cavity each contact configured to contact a corresponding contact of the secondary device when the secondary device is in the cavity.
  • the secondary device comprises: a housing having a proximal end and a distal end; a cavity, provided in the proximal end of the housing, configured to receive an aerosol-generating article; a power supply; at least one electrical heating element; and a plurality of electrical contacts provided at the distal end of the housing.
  • the maximum radius of a cross-section of the housing adjacent the proximal end is greater than the maximum radius of a cross-section of the housing adjacent the distal end.
  • the maximum radius of the cross-section of the secondary device housing adjacent the proximal end is greater than the maximum radius at the open end of the primary device cavity.
  • the longitudinal length of the cavity in the primary device is substantially equal to the longitudinal distance from the distal end of the secondary device to the portion of the secondary device having the greater maximum radius.
  • providing such a housing prevents the device from being fully inserted into a charging device of an aerosol-generating system when the device is inserted incorrectly. This may reduce the risk of the device becoming stuck in the charging device when a user inserts the device in the incorrect orientation.
  • the cross-section of the housing having the greater maximum radius is provided at a distance of less than 25% of the longitudinal length of the housing from the proximal end. Providing the cross-section of the housing having the greater maximum radius at this position advantageously prevents the device from being inserted very far into a charging device incorrectly, which provides an immediate and very obvious indicator to the user that the device is inserted incorrectly.
  • the maximum radius of a cross-section of the housing adjacent the proximal end is preferably between about 1 10% and about 125% of the maximum radius of a cross-section of the housing adjacent the distal end.
  • the maximum radius of the cross-section of the housing adjacent the proximal end may be formed by a protrusion provided on the external surface of the housing.
  • the protrusion preferably has a smooth cross-sectional profile.
  • the protrusion may extend around the entire circumference of the housing. Preferably, the protrusion extends around only a portion of the circumference of the housing.
  • the protrusion is preferably a smooth bulge to provide the user with a satisfactory usage experience.
  • the bulge may extend between about 1 mm and about 3 mm from the surface of the housing.
  • the bulge may have a longitudinal length of between about 1 mm and about 5 mm.
  • the cross-sectional shape of the cavity in the primary device preferably matches the cross- sectional shape of the secondary device housing adjacent the distal end.
  • the cross-sectional shape may be non-symmetrical so that the secondary device may be keyed to the primary device to ensure the secondary device is inserted in the correct rotational alignment. In this way, the electrical connections may be correctly made.
  • the longitudinal length of the cavity in the primary device may be less than the longitudinal distance from the distal end of the secondary device to the portion of the secondary device having the greater maximum radius. In this way, the portion adjacent the proximal end does not engage with the primary device, and the secondary device can be fully inserted into the primary device to enable the electrical connections to be made.
  • the term "longitudinal” refers to a direction from bottom to top or vice versa.
  • the term “transverse” refers to a direction perpendicular to the longitudinal direction.
  • the primary device is preferably a charging device for recharging the power supply in the secondary device.
