  • An aerosol generating device can receive an article comprising aerosol generating material for heating.
  • An "article” in this context is a component that includes or contains in use the aerosol generating material, which is heated to volatilise the aerosol generating material, and optionally other components in use.
  • a user may insert the article into the aerosol generating device before it is heated to produce an aerosol, which the user subsequently inhales.
  • the article may be, for example, of a predetermined or specific size that is configured to be placed within a heating chamber of the device which is sized to receive the article.
  • Figures 1A to 1C show perspective views of an aerosol provision device 100 in three different operational configurations, wherein an "operational configuration" may result from at least one of certain components of device 100 being operated by a user or an article being inserted into the device 100.
  • the aerosol provision device 100 is configured to generate aerosol from an aerosol generating article, which is not shown in Figures 1A and 1B and which is shown and referred to with reference numeral 200 in Figure 1C .
  • the aerosol provision device 100 is an elongate structure, extending along a longitudinal axis.
  • the aerosol provision device 100 has a proximal end 101, which will be closest to the user (e.g. the user's mouth) when in use by the user to inhale the aerosol generated by the aerosol provision device 100, as well as a distal end 102 which will be furthest from the user when in use.
  • the proximal end 101 may also be referred to as the "mouth end” or "top end”.
  • the proximal end 101 of the aerosol provision device 100 is formed by a subunit commonly referred to as an extractor 110, whose function is also described below.
  • the aerosol generating article 200 may be inserted, in use, into the aerosol provision device 100.
  • the aerosol provision device 100 or more precisely the extractor 110, comprises an opening to a receptacle 103, as shown in Figure 1B , into which the aerosol generating article 200 may be inserted, and which is not fully shown for reasons of clarity.
  • the aerosol generating article 200 may form part of the aerosol provision device 100, or the aerosol provision device 100 and the article 200 may be understood as parts of an aerosol generating system as referred to with reference numeral 1000 in Figure 1C .
  • the aerosol provision device 100 also accordingly defines a proximal direction, which is directed towards the user when in use. Further, the aerosol provision device 100 also likewise defines a distal direction, which is directed away from the user when in use.
  • proximal and distal as applied to features of the device 100 will be described by reference to the relative positioning of such features with respect to each other in a proximal-distal direction along a longitudinal axis which is not shown for reasons of conciseness.
  • the device 100 includes a slidable lid unit 150.
  • the slidable lid unit 150 may be closed so as to cover the opening to the receptacle 103 of the aerosol provision device 100 as shown in Figure 1A , and therefore restricts access to the receptacle 103.
  • the slidable lid unit 150 may be held in certain positions by magnets associated with the lid unit 150 and/or a body of the device 100 beneath the lid unit 150. As shown in Figures 1B and 1C , the lid unit 150 may be opened to provide or restrict access to the opening to the receptacle 103.
  • One or more user-operable control elements 104 such as buttons, sliders or the like which can be used to operate the aerosol provision device 100, may be provided on a side of the aerosol provision device 100.
  • Figures 2A and 2B show the device 100 already shown in Figures 1A to 1C in a side view, wherein Figure 2A illustrates an assembled state and Figure 2B shows a disassembled or drawn-apart state.
  • the device 100 comprises, apart from the extractor 110 already shown before, a further subunit commonly referred to as a main body 120 with structures surrounding a part of the extractor 110, including in particular control electronics and one or more batteries, and a housing unit 130.
  • an aerosol When in use, an aerosol is withdrawn from the article 200 by a user via his or her mouth and inhaled, but in between puffs, aerosol will continue to form and will be emitted from the article 200.
  • Some of the aerosol and other moisture may condense in the device 100 on some, particularly colder, surfaces, generating unwanted moisture and sticky residues, as further explained below.
  • This phenomenon but also the surface temperature of the device 100, is a critical item for customer experience.
  • a root cause for high surface temperature is that a heating isolation may not be sufficient, and a root cause for aerosol condensation may be a lack of condensation retaining features on the device 100 or that a condensation spread trace may be too small.
  • Embodiments as disclosed herein are provided to at overcome these disadvantages, providing both an improved insulation and a condensate retention in certain embodiments. Embodiments as disclosed herein therefore provide an improved user experience as an outer surface of a device 100 may stay cooler and less condensate may form.
  • Figures 3A and 3B show certain parts of the device 100 and the article 200 essentially shown in the previous Figures already, but in a non-inventive configuration, in a drawn-apart view ( Figure 3A ) and in an assembled view ( Figure 3B ).
  • the extractor 110 which is shown here again, forms part of a removal mechanism which is used to aid extraction of the article 200 by pulling the article off a heater 125, or, more specifically, a pin-shaped part 125a thereof in a reliable way.
  • the pin-shaped element 125a protrudes from the main body 120 shown before into a chamber in which the receptacle 103 of the extractor 110 is received.
  • the receptacle 103 is surrounded, and defined, by a peripheral wall 111.
  • Figure 4 shows a simplified schematic view of certain parts of a device 100 as already illustrated before.
  • Figure 4 in particular is not drawn to scale and particularly certain distances and/or void spaces are exaggerated to demonstrate certain aspects for better understanding of embodiments disclosed herein.
  • the main body 120 which may be surrounded, as before, by a housing 130, is shown in dashed outline only, and it may comprise any suitable structures 120a surrounding the extractor 110 which is also shown in a strongly simplified view.
  • Embodiments disclosed herein may help to reduce or eliminate condensate formation or draining off of condensate formed, and may also provide further advantages in connection with heat conduction to the outer housing of the device 100.
  • a root cause for condensation may be a lack of condensation retaining features on an outer surface of the peripheral wall 111 or a too small condensation surface, and embodiments disclosed herein are intended to increase this surface.
  • Figures 5A and 5B show enlarged views of extractor 110 in a view corresponding to Figures 2A and 2B (see Figure 5A ) and in a view orthogonal thereto (see Figure 5B ) according to an embodiment.
  • the extractor 110 comprises the receptacle 103 configured for receiving at least a portion of the article, into which the heater 125 or the pin-shaped structure element 125a thereof protrudes in assembled state, as already shown several times before.
  • the peripheral wall enclosing and defining the receptacle 103 is again indicated with 111 in Figures 5A and 5B .
  • a part or subregion 113 of an outer surface of the peripheral wall 111 is provided as a structured surface, wherein, in this specific example, meandering grooves 114 are provided as structuring elements.
  • the "outer surface” is to be understood to be the surface of the peripheral wall facing away from the article 200 when the latter is inserted into the receptacle 103 and to further structures of the base unit 120.
  • a meandering groove 114 may, however, only be one of a plurality of structuring elements which may be provided in certain embodiments.
  • Structuring elements may be selected on the basis of specific requirements and may be provided in a part of the enclosing structure, particularly in a bottom region where condensate may particularly form and/or heating structures are arranged. They may be prepared in the form of joint or disjoint structures or groups of structures of any type conceivable.
  • Providing the structuring elements serves the purpose of generating an air gap between the peripheral wall 111 and its surrounding structures, and also of forming retention regions for condensate which therefore cannot run off and reach the outside of the device 100 and the environment or sensitive parts within the base unit 120.
  • the structuring elements of the structured surface of the peripheral wall 111 may comprise disjoint indentations or protrusions as illustrated in these Figures in only a limited number of examples, including indentations with, in a projection to the surface, a quadratic, a pentagonal, a trigonal, a rectangular, a circular or a hexagonal shape.
