Definitions

  • the present disclosure relates generally to an aerosol generating device, and more particularly to an aerosol generating device for heating an aerosol generating material to generate an aerosol for inhalation by a user.
  • Embodiments of the present disclosure also relate to an aerosol generating system.
  • One approach is to provide an aerosol generating device which employs a resistive heating system.
  • a resistive heating element is provided to heat aerosol generating material positioned within a cavity of the device and thereby generate a vapour which typically cools and condenses to form an aerosol for inhalation by a user of the device.
  • the resistive heating system can be an internal resistive heating system in which one or more resistive heating elements (e.g. a heating blade arranged within the cavity of the device) are arranged to be positioned within the aerosol generating material during use of the aerosol generating device and/or an external resistive heating system in which one or more resistive heating elements are arranged to at least partially surround the aerosol generating material.
  • the use of an internal resistive heating system may be preferred because the heating process is generally more efficient and requires a lower power input due to the fact that most of the heat is transferred directly from the heating element to the aerosol generating material, with minimal heat transfer to other components. It would be desirable to provide an aerosol generating device and an aerosol generating system which has a reduced power requirement and/or which provides improved control over the heating of the aerosol generating material.
  • an aerosol generating device comprising: a housing defining a cavity for receiving an aerosol generating material; a power source and a controller; a plurality of heating circuits for heating the aerosol generating material, each heating circuit comprising an electrical circuit component movable between a first position in which the electrical circuit component does not extend into the aerosol generating material and a second position in which the electrical circuit component extends into the aerosol generating material; wherein the controller is configured to control the power source to independently supply electrical energy to one or more of the heating circuits when the electrical circuit components are in the second position.
  • the aerosol generating device is adapted to heat the aerosol generating material, without burning the aerosol generating material, to volatise at least one component of the aerosol generating material and thereby generate a vapour which cools and condenses to form an aerosol for inhalation by a user of the aerosol generating system/device.
  • vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapour can be condensed to a liquid by increasing its pressure without reducing the temperature
  • aerosol is a suspension of fine solid particles or liquid droplets, in air or another gas.
  • aerosol and ‘vapour’ may be used interchangeably in this specification, particularly with regard to the form of the inhalable medium that is generated for inhalation by a user.
  • aerosol generating material can easily be positioned in the cavity when the electrical circuit components are in the first position, whilst movement of the electrical circuit components to the second position may advantageously help to retain the aerosol generating material in the cavity.
  • Each electrical circuit component may be movable between a first position in which the electrical circuit component does not extend into the cavity and a second position in which the electrical circuit component extends into the cavity and into a portion of the aerosol generating material. Such an arrangement may facilitate insertion of aerosol generating material into the cavity, by ensuring that the electrical circuit components do not extend into the cavity when in the first position.
  • the electrical circuit components may be simultaneously or sequentially movable between the first and second positions. Movement of the electrical circuit components is thus achieved in a simple manner.
  • the controller may be configured to control the power source to sequentially supply electrical energy to one or more of the heating circuits when the electrical circuit components are in the second position.
  • the cavity may be an elongate cavity having a longitudinal axis and the electrical circuit components may be spaced along the longitudinal axis. Such an arrangement may facilitate positioning of aerosol generating material in the cavity and/or optimal heating of aerosol generating material positioned in the cavity.
  • the aerosol generating device may comprise a positioning mechanism configured to move the electrical circuit components between the first position and the second position in a direction substantially orthogonal to the longitudinal axis. Movement of the electrical circuit components may, therefore, be achieved with relative ease.
  • the positioning mechanism may be arranged for simultaneously moving the electrical circuit components from the first position to the second position.
  • the positioning mechanism may comprise a radially movable pusher.
  • the radially movable pusher may be manually activated by a user.
  • the positioning mechanism may be arranged for sequentially moving the electrical circuit components from the first position to the second position.
  • the positioning mechanism may comprise an axially movable pusher.
  • the axially movable pusher may be manually activated by a user.
  • each electrical circuit component may comprise a pair of electrical contacts
  • the controller may be configured to control the power source to independently supply electrical energy to one or more pairs of the electrical contacts when the electrical contacts are in the second position, and possibly to sequentially supply electrical energy to one or more pairs of the electrical contacts when the electrical contacts are in the second position.
  • the electrical contacts may be spaced from a heating element positioned in the aerosol generating material when the electrical contacts are in the first position and may be arranged to contact the heating element at different locations when the electrical contacts are in the second position.
  • the contact between the electrical contacts and the heating element at different locations allows different sections of the heating element to be selectively heated. This in turn allows different portions or regions of the aerosol generating material to be selectively heated.
  • the heating element may be mounted on the housing and may project into the cavity. With such an arrangement, the heating element is a component part of the aerosol generating device.
  • the heating element may alternatively be provided with the aerosol generating material, for example in the form of an aerosol generating article comprising an aerosol generating material and a heating element positioned in the aerosol generating material.
  • the heating element forms part of the consumable element, i.e., the aerosol generating article. This may lead to a further improvement in heating efficiency and may simplify the structure of the aerosol generating device by avoiding the need to provide a heating element that is a component part of the device. This may in turn avoid the need for cleaning and/or replacement of the heating element.
  • each electrical circuit component may comprise a heating element.
  • the heating elements are a component part of the aerosol generating device.
  • the controller may be configured to control the power source to independently supply electrical energy to one or more of the plurality of heating elements when the heating elements are in the second position, and possibly to sequentially supply electrical energy to one or more of the plurality of heating elements when the heating elements are in the second position.
  • the or each heating element may comprise a resistive heating element.
  • the or each heating element may comprise an electrically resistive material.
  • suitable electrically resistive materials include, but are not limited to, metals, metal alloys, electrically conductive ceramics, for example tungsten and alloys thereof, and composite materials comprising a metallic material and a ceramic material.
  • the heating element forms part of the consumable element, i.e., the aerosol generating article.
  • This may simplify the structure of the aerosol generating device by avoiding the need to provide a heating element that is a component part of the device. The need for cleaning and/or replacement of the heating element is thereby eliminated.
  • the aerosol generating article may comprise an aerosol generating material circumscribed by a paper wrapper.
  • the aerosol generating article may be formed substantially in the shape of a stick.
