Definitions

  • the present disclosure relates to a device assembly for retaining a removable battery module in an aerosol generation device.
  • the present disclosure also relates to a battery assembly for an aerosol generation device.
  • the electrical connection between the battery cell and the PCB of an aerosol generation device is usually made using one or more connectors. These connectors are present on both the PCB and the battery and require an appropriate place that is easy to access. There is also a requirement on the PCB to provide enough space for the connectors.
  • the battery cell is often irreversibly coupled (for example, welded) to the internal components of the aerosol generation device.
  • a challenge associated with the above is providing a device that allows fora replaceable battery while maintaining a proper electrical connection.
  • a device assembly for retaining a removable battery module in an aerosol generation device and a battery assembly for an aerosol generation device including the features as set out in the claims.
  • a device assembly for retaining a removable battery module in an aerosol generation device.
  • the device assembly comprises a printed circuit board comprising one or more protrusions configured to abut said battery module, in use.
  • the device assembly comprises one or more electrical contacts configured to electrically connect to said battery module, in use.
  • the device assembly comprises a fixture configured to mechanically urge said battery module towards the one or more protrusions, in use.
  • the electrical contacts on the PCB remove the need for connectors, thus providing a more efficient use of internal space of the device and allowing for easy battery disconnection. More space is therefore provided on the PCB for other components, or to miniaturise the PCB.
  • the presence of a protrusion on the PCB and the fixture allows the device to produce a lever effect on a battery module, thus providing a high pressure, through the mechanical urging, on the battery module. This ensures that a good electrical contact is made between the electrical contacts of the device assembly and a battery module.
  • connection of the battery to the PCB does not require any tools, thereby making it easy for a user to remove a depleted battery and install a new battery.
  • the one or more electrical contacts may be located on the one or more protrusions.
  • the fixture may be configured to mechanically urge said battery module in a direction substantially perpendicular to a longitudinal axis of said battery module.
  • the fixture may comprise a resiliently deformable member configured to mechanically urge said battery module towards the protrusions of the printed circuit board, in use.
  • this provides a lever effect, thus achieving a high mechanical pressure connection between the PCB and a battery module.
  • the fixture may be a cap comprising a tapered surface, which is configured to contact an end of said battery module and mechanically urge said battery module towards the protrusions of the printed circuit board, in use.
  • the mechanical urging may be additionally reinforced by the cap, thus simplifying the design of the device assembly.
  • the cap enables easy removal and insertion of a battery module whilst also providing a means for urging said battery module towards the protrusions, thus providing a lever effect.
  • the fixture may comprise one or more locking pins.
  • the locking pins may be configured to engage one or more locking holes on a battery cell support of said battery module.
  • the locking pins provide a mechanical urging that forces a battery module towards the protrusions of the PCB, thus allowing for a simple, mechanical connection between the PCB and the battery module.
  • Pouch cells are more easily manipulated; therefore, the shape of the pouch cell may be adjusted to fit the device. Therefore, the device assembly may be made smaller.
  • the tabs may be flush with a surface of the pouch, therefore facilitating a strong mechanical connection between the battery module and the PCB.
  • a more secure connection between the battery module and the PCB may be provided. Additionally, urging the battery module in a direction substantially perpendicular to a longitudinal axis of the battery cell of the battery module may lead to a more efficient use of space with the aerosol generation device as there needn’t be connections at the ends of the battery module. Further, the requirement for additional connectors is avoided.
