Definitions

  • the present disclosure relates generally to a printed circuit board assembly for an aerosol generating device, and in particular a device that is adapted to heat aerosol generating material to generate an aerosol for inhalation by a user.
  • the present disclosure also relates generally to an aerosol generating device.
  • the present disclosure is particularly applicable to a portable (hand-held) aerosol generating device.
  • a commonly available reduced-risk or modified-risk device is the heated material aerosol generating device, or so-called heat-not-bum device.
  • Devices of this type generate an aerosol or vapour by heating an aerosol generating material to a temperature typically in the range 150°C to 300°C. This temperature range is quite low compared to an ordinary cigarette. Heating the aerosol generating material to a temperature within this range, without burning or combusting the aerosol generating material, generates a vapour which typically cools and condenses to form an aerosol for inhalation by a user of the device.
  • the aerosol generating device will typically include a printed circuit board assembly with various electronic components mounted to a printed circuit board.
  • the electronic components may be part of one or more circuits for operating the device.
  • some electronic components are electrically connected to the printed circuit board by means of a suitable electrically conductive connecting member (e.g., a wire, a component pin, or a flexible printed circuit board).
  • An exposed electrically conductive terminal provided on a surface of the printed circuit board makes an electrical connection between the printed circuit board and these electronic components by means of the connecting member.
  • the printed circuit board will normally be substantially rectangular. Each energy storage device terminal may be electrically connected respectively to one of a pair of electrically conductive paths.
  • a first path may be electrically connected to one of the energy storage device terminals (e.g., a positive energy storage device terminal) and may extend along a first surface and/or a second surface of the printed circuit board.
  • the printed circuit board may be a double-sided circuit board - i.e., with electrically conductive paths on top and bottom surfaces.
  • a second path may be electrically connected to the other one of the energy storage device terminals (e.g., a negative energy storage device terminal) and may extend along a first surface and/or a second surface of the printed circuit board.
  • the first and/or second paths may extend substantially diagonally along the first surface and/or the second surface of the printed circuit board with respect to the edges of the printed circuit board. Because the pair of energy storage device terminals are located outside the pair of temperature sensor terminals, providing a simple and straight electrically conductive path may be difficult due to interference with other electronic components and other paths. If an electrically conductive path has a right angle or acute angle, it may generate electrical noise and losses because of the difference in passed electric current between the inside and outside corners of the path. Extending the first and/or second paths as proposed provides paths having only obtuse angles which is beneficial in reducing electrical noise and losses.
  • the printed circuit board may include a first notch in a first edge and a second notch in a second, opposite, edge.
  • the printed circuit board may be held in a holder which may be made of a suitable plastics material, for example.
  • the holder may include locating features which are received in the notches to properly position and locate the printed circuit board within the holder.
  • the first and second paths - or at least the diagonally extending parts thereof - may be located in a first region of the printed circuit board between the notches and a third edge of the printed circuit board at which the energy storage device terminals and the temperature sensor terminals are located.
  • At least the diagonally extending parts of the first and second paths may be located in a first region of the printed circuit board that extends between the third edge and a line that extends across the printed circuit board between the first and second notches.
  • To securely hold the printed circuit board e.g., if the aerosol generating device is dropped
  • such notches may require the electrically conductive paths to take a more complex shape.
  • the proposed arrangement where at least the diagonally extending part of the first and second paths i.e., having only obtuse angles) are located in the first region means that the paths avoid interfering with the notches. This means that secure holding of the printed circuit board and the reduction of electrical noise and losses are realised at the same time.
  • the first and second paths may also extend outside of the first region.
  • an aerosol generating device comprising a printed circuit board assembly with a printed circuit board that comprises a pair of energy storage device terminals and a pair of charging terminals.
  • the aerosol generating device further comprises an energy storage device electrically connected to the energy storage device terminals, and a charging assembly electrically connected to the charging terminals.
  • the printed circuit board may also comprise a pair of temperature sensor terminals.
  • the aerosol generating device may further comprise a temperature sensor (e.g., an NTC thermistor, a PTC thermistor, or other suitable temperature sensor) electrically connected to the temperature sensor terminals.
  • the pair of temperature sensors may be located between the pair of energy storage device terminals at the same edge of the printed circuit board.
  • the aerosol generating device may further comprise a housing that surrounds the printed circuit board assembly, the energy storage device, and the charging assembly.
  • the housing may be made of any suitable material, e.g., a plastics material.
  • the housing may have a first inner surface and a second, opposite, inner surface.
  • the energy storage device may have a first side that faces towards the first inner surface of the housing and a second side that faces towards the second inner surface of the housing.
  • the printed circuit board may have a first surface that faces towards the first inner surface of the housing and a second surface that faces towards the second inner surface of the housing.
  • the aerosol generating device may be adapted to receive, in use, an aerosol generating article.
  • the aerosol generating article may be received in a body or housing of the aerosol generating device, for example.
  • the aerosol generating article may be removably received in the body or housing.
  • the aerosol generating article may be of any suitable type and may include an aerosol generator adapted to heat aerosol generating material to generate an aerosol for inhalation by a user.
  • the aerosol generator may include a heater.
  • a heater may alternatively be part of the aerosol generating device.
  • the aerosol generator may be adapted to heat aerosol generating material.
  • the aerosol generating material may be a liquid which may be stored in the aerosol generating article.
  • the liquid aerosol generating material may soak into a wick (e.g., a cotton wick) and is then heated by the heater to produce a vapour that cools and condenses to form an aerosol that may then be inhaled.
  • a wick e.g., a cotton wick
  • the wick may be omitted in some cases and the liquid aerosol generating material may be directly stored in a cavity of the aerosol generating article.
  • the aerosol generating article may be formed as an integrated component (or “pod”) that includes a liquid store, a liquid transfer element or wick, and a heater.
  • One or more electrical contacts may also be provided to establish an electrical connection between the heater and the energy storage device.
