Definitions

  • the present invention relates to an aerosol-generating device.
  • Aerosol-generating device for generating an inhalable vapor.
  • Such devices may heat aerosol-forming substrate to a temperature at which one or more components of the aerosol-forming substrate are volatilised without burning the aerosol-forming substrate.
  • Aerosol-forming substrate may be provided as part of an aerosol-generating article.
  • the aerosol-generating article may have a rod shape for insertion of the aerosol-generating article into a cavity, such as a heating chamber, of the aerosol-generating device.
  • a heating element may be arranged in or around the heating chamber for heating the aerosol-forming substrate once the aerosol-generating article is inserted into the heating chamber of the aerosol-generating device.
  • the aerosol-generating article During insertion of the aerosol-generating article into the heating chamber, the aerosol-generating article should be inserted a predetermined distance into the heating chamber.
  • the reason for that is that the aerosol-forming substrate of the aerosol-generating article should be placed in an optimal position relative to the heating element of the aerosol-generating device.
  • unwanted debris such as residues of aerosol-forming substrate may accumulate in the heating chamber over time. This may influence the insertion of the aerosol-generating article, as the aerosol-generating article may abut the unwanted debris during insertion. The aerosol-generating article may then not be positioned optimally within the heating chamber.
  • US 2020/0236999 A1 describes an aerosol-generating device, including a housing having a chamber; an induction coil disposed around at least a portion of the chamber; a heating compartment configured to receive an aerosol-generating article and being detachably insertable into the chamber of the housing.
  • the invention provides an aerosol-generating device comprising a cavity for receiving an aerosol-generating article.
  • the aerosol-generating article comprises an aerosol-forming substrate.
  • the device further comprises a stopper.
  • the stopper is arranged at a distal portion or distal of the cavity.
  • the stopper is configured to stop the aerosol-generating article, when the aerosol-generating article contacts the stopper.
  • the stopper is arranged transversally spanning the distal portion of the cavity.
  • the stopper is arranged such that air can flow from distal of the stopper around the stopper into the cavity.
  • the stopper has a circular cross-section in a plane parallel to a longitudinal axis of the cavity and perpendicular to a longitudinal axis of the stopper.
  • the stopper securely stops an aerosol-generating article inserted into the cavity.
  • the term "to stop” refers to the stopper stopping the consumable at a position along the longitudinal axis of the cavity such that further insertion is faced with resistance.
  • the stopper prevents accumulation of unwanted debris in the distal portion of the cavity, since the unwanted debris falls left and right of the spanning part of the stopper. Particularly due to airflow being enabled around the stopper, unwanted debris may escape through this unobstructed space adjacent to the stopper.
  • the stopper automatically sheds unwanted debris off the stopper due to the spanning arrangement of the stopper.
  • the unwanted debris is pushed to the left and right of the spanning part of the stopper during one or more of insertion and removal of the aerosol-generating article. If the aerosol-generating article contacts the stopper, the unwanted debris is pushed off the spanning part of the stopper by the aerosol-generating article.
  • the cavity of the aerosol-generating device may have an open end into which the aerosol-generating article is inserted.
  • the open end may be a proximal end.
  • the cavity may have a base opposite the open end.
  • the base may be arranged at the distal portion of the cavity.
  • the base of the cavity may be arranged distal of the cavity.
  • the base may comprise one or more air apertures allowing airflow into the cavity.
  • the base is preferably configured as a through hole.
  • the stopper may be arranged at the base or directly adjacent the base in the cavity.
  • the stopper may be arranged spanning the base.
  • the shedding of unwanted debris from the stopper may lead to the unwanted debris being pushed off the stopper and into the open base. Unwanted debris may be easily removed from the open base. Multiple options are possible for removing unwanted debris from the open base.
  • the open base may fully extend through the aerosol-generating device such that unwanted debris can be removed through this passage. This passage may be an airflow channel. A cleaning tool may be inserted into this passage to remove the unwanted debris.
  • a further option is to provide a recess in the open base in which the unwanted debris can accumulate. At certain intervals, a user may have to clean the recess.
  • the open end may be arranged proximal of the cavity.
  • the cavity may have an elongate extension.
  • the cavity may have a longitudinal central axis.
  • a longitudinal direction may be the direction extending between the open and closed ends along the longitudinal central axis.
  • the longitudinal central axis of the cavity may be parallel to or along the longitudinal axis of the aerosol-generating device.
  • the cavity may be configured as a heating chamber.
  • the cavity may have a cylindrical shape.
  • the cavity may have a hollow cylindrical shape.
  • the cavity may have a shape corresponding to the shape of the aerosol-generating article to be received in the cavity.
  • the cavity may have a circular cross-section.
  • the cavity may have an elliptical or rectangular cross-section.
  • the cavity may have an inner diameter corresponding to the outer diameter of the aerosol-generating article.
  • the airflow channel may run through the cavity. Ambient air may be drawn into the aerosol-generating device through the airflow channel distal of the cavity and the open base of the cavity, into the cavity and towards the user through the airflow channel. When entering the cavity, the air may flow around the stopper spanning the distal portion of the cavity.
  • the stopper thus has the functionality of enabling a secure stopping action of the inserted aerosol-generating device while automatically shedding unwanted debris into the open base of the cavity and while allowing airflow into the cavity around the stopper.
  • a mouthpiece may be arranged or a user may directly draw on the aerosol-generating article.
  • the airflow channel may extend through the mouthpiece.
  • the stopper has a circular cross-section. Providing the stopper with a circular cross-section has the advantage that unwanted debris slides off the stopper more easily.
  • Any cross-sectional shape of the stopper is defined as a shape in a plane parallel to a longitudinal axis of the cavity and perpendicular to a longitudinal axis of the stopper.
  • the stopper may be arranged crossing the longitudinal central axis of the cavity. In other words, the stopper may be arranged centrally crossing the cavity. Such a symmetrical arrangement of the stopper may improve the stopping action of the stopper and may improve the shedding of unwanted debris.
  • the stopper may be arranged perpendicular to the longitudinal axis of the cavity.
  • the stopper may be a pin.
  • a pin-shaped stopper is easy to manufacture while improving the stopping action of the stopper and automatically shedding unwanted debris.
  • the length of the pin may be longer than the inner diameter of an inner sidewall of the cavity. This may facilitate a secure mounting of the pin.
  • the stopper may be one or more of a pin, a bar, a rod, a pole, a shaft, a beam, a rail, a strut, a small pole, a spoke, a stem, a spoke and a crossbar.
  • the stopper may have a curved surface.
  • the curved surface may improve the shedding action of the stopper of unwanted debris.
  • the stopper may comprise a surface treatment to make the stopper more slippery. Providing a slippery stopper surface improves the automatic shedding of unwanted debris off the surface of the stopper.
  • the stopper may be elongate.
  • the length of the stopper may be longer, preferably substantially longer, than the width of the stopper.
  • the stopper may be straight.
  • the stopper may be straight in the extension direction of the longitudinal axis of the stopper.
  • the longitudinal axis of the stopper may be perpendicular to a longitudinal axis of the cavity. Providing a straight stopper is easy to manufacture while creating a secure stop for the insertion of the aerosol-generating article.
  • the stopper may be configured cross-shaped.
  • a cross-shaped stopper may further improve the stopping ability of the stopper.
  • the cross-shaped stopper may be arranged in a plane. This plane may be perpendicular to the longitudinal axis of the cavity.
  • Each member of the cross-shaped stopper may be shaped as described herein. Exemplarily, each member of the cross-shaped stopper may have a circular cross-section, may have a curved surface, be configured as a pin etc.
  • the stopper may be arranged such that air can flow from distal of the stopper around the stopper into the cavity.
  • air can flow around the stopper.
  • air can flow around the stopper.
  • This may advantageously establish a fluid connection between the cavity and the airflow channel arranged distal of the cavity via the stopper.
  • the airflow channel may have a double functionality of enabling airflow into the cavity and at the same time of receiving the unwanted debris that is shed off the stopper.
  • the airflow channel may thus further be configured as a cleaning channel.
  • the stopper may be arranged at the base of the cavity.
  • the cavity may be configured as a heating chamber.
  • the aerosol-generating device may comprise a heating element arranged at least partly surrounding the cavity.
  • the heating element may be configured to heat the heating chamber to between 160 °C and 300 °C, preferably between 180 °C and 270 °C, more preferably between 200 °C and 250 °C.
  • the aerosol-generating device may comprise an airflow channel distal of the cavity and the stopper.
  • the airflow channel may be arranged to enable airflow into the cavity past the stopper.
  • the stopper may be arranged in the airflow channel.
  • the stopper may be arranged between the cavity and the airflow channel.
  • the distal portion of the cavity may have an inner diameter of between 7.0 mm and 7.6 mm, preferably between 7.1 mm and 7.5 mm, more preferably between 7.2 mm and 7.4 mm, most preferably around 7.3 mm.
  • the stopper may be arranged closer to a proximal end of the aerosol-generating device than to a distal end of the aerosol-generating device.
  • the stopper may be made from PEEK.
  • the stopper may be configured to withstand temperatures of up to around 340 °C.

The power may be supplied to the heating element in the form of pulses of electrical current.
  • the electric circuitry may be configured to monitor the electrical resistance of the heating element, and preferably to control the supply of power to the heating element dependent on the electrical resistance of the heating element.
  • the aerosol-generating device may comprise a power supply, typically a battery, within a main body of the aerosol-generating device.
  • the power supply is a Lithium-ion battery.
  • the power supply may be a Nickel-metal hydride battery, a Nickel cadmium battery, or a Lithium based battery, for example a Lithium-Cobalt, a Lithium-Iron-Phosphate, Lithium Titanate or a Lithium-Polymer battery.
  • the power supply may be another form of charge storage device such as a capacitor.
  • the power supply may require recharging and may have a capacity that enables to store enough energy for one or more usage experiences; for example, the power supply may have sufficient capacity to continuously generate aerosol for a period of around six minutes or for a period of a multiple of six minutes. In another example, the power supply may have sufficient capacity to provide a predetermined number of puffs or discrete activations of the heating element.
  • an aerosol-generating article refers to an article comprising an aerosol-forming substrate that is capable of releasing volatile compounds that can form an aerosol.
  • an aerosol-generating article may be a smoking article that generates an aerosol that is directly inhalable into a user's lungs through the user's mouth.

  • suitable metal alloys include stainless steel, nickel-, cobalt-, chromium-, aluminium- titanium- zirconium-, hafnium-, niobium-, molybdenum-, tantalum-, tungsten-, tin-, gallium-, manganese-, gold- and iron-containing alloys, and super-alloys based on nickel, iron, cobalt, stainless steel, Timetal ® and iron-manganese-aluminium based alloys.
  • the electrically resistive material may optionally be embedded in, encapsulated or coated with an insulating material or vice-versa, depending on the kinetics of energy transfer and the external physicochemical properties required.
  • the aerosol-generating device 10 further comprises a heating element 20.
  • the heating element 20 is configured as a resistive hearing element or as an induction heating element 20.
