Definitions

  • the present invention relates to an aerosol delivery device, and, more particularly but not exclusively, to an aerosol delivery device for a smoking substitute system.
  • the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
  • Such smoking substitute devices can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • smoking substitute devices are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
  • Other smoking substitute devices do not generally resemble a cigarette (for example, the smoking substitute device may have a generally box-like form).
  • the present invention relates to an aerosol delivery device in which an airflow path around an airflow-directing member (baffle) within a vaporising chamber has a reduced cross-sectional area to match a minimum upstream cross-sectional area of the airflow path in the vaporising chamber.
  • an aerosol delivery device having a chamber airflow path through a vaporising chamber housing a vaporiser, the chamber airflow path extending through at least one aperture defined by an upstream edge of a transverse baffle mounted downstream from the vaporiser, wherein the chamber airflow path through the at least one aperture has a transverse cross-sectional area that is substantially equal or less than a minimum transverse cross-sectional area of the chamber airflow path downstream from the at least one aperture.
  • the chamber airflow path has a portion extending from the aperture to a downstream edge of the transverse baffle wherein the chamber airflow path at the downstream edge of the transverse baffle has a transverse cross-sectional area that is substantially equal or less than a minimum transverse cross-sectional area of the chamber airflow path downstream from the downstream edge of the transverse baffle.
  • the chamber airflow path is partly defined by one or more walls of the vaporising chamber.
  • the at least one aperture may be defined by the upstream edge of the baffle and the opposing sidewall of the chamber.
  • the transverse width of the aperture i.e. the transverse spacing between the upstream edge of the baffle and the sidewall of the chamber
  • the transverse spacing between the downstream edge of the baffle and the sidewall of the vaporising chamber equals the transverse spacing between the downstream edge of the baffle and the sidewall of the vaporising chamber.
  • the aperture (and the upstream/downstream edges of the baffle) may be offset transversely (i.e. laterally) from the longitudinal axis of the passage (e.g. may be radially outwards of the passage opening).
  • the wireless interface 124 is preferably configured to communicate wirelessly with another device, for example a mobile device, e.g. via Bluetooth ® .
  • the wireless interface 124 could include a Bluetooth ® antenna.
  • Other wireless communication interfaces, e.g. WiFi ® are also possible.
  • the wireless interface 124 may also be configured to communicate wirelessly with a remote server.
  • the additional components 128 of the main body 102 may also comprise a charging port (e.g. USB or micro-USB port) configured to receive power from the charging station (i.e. when the power source 118 is a rechargeable battery). This may be located at the lower end 110 of the main body 102.
  • the electrical interface 126 discussed above may be configured to act as a charging port configured to receive power from the charging station such that a separate charging port is not required.
  • the chamber air flow path i.e. the airflow through the vaporising chamber 156 from proximal the vaporiser 132 to the passage opening 158 extends is bifurcated and has two branches extending through the apertures 178 in a generally longitudinal direction between the upstream edges 176 and the downstream edges 179.
  • the transverse cross-sectional area of the chamber air flow path as it passes between the upstream and downstream edges 176, 179 is constant within each branch and equal between the two branches.
  • the transverse cross-sectional area of the chamber airflow path between the upstream and downstream edges 176, 179 in each branch is equal to the minimum (smallest) cross-sectional area of the chamber airflow path downstream of the downstream edges 179 i.e. between the downstream edges 179 and the passage opening 158.
  • the chamber airflow path between the apertures 178 and the passage opening 158 is constant. The chamber airflow path will deflect radially towards the passage opening 158 at the downstream edges 179.
