Aerosol Generation Device

Abstract

An aerosol generation device configured to heat a consumable comprising tobacco includes: a housing; and a reel arranged to rotate on an axis of rotation within the housing so as to wind a consumable around the reel. The consumable has a winding dimension along which it is wound around the reel. The reel comprises a positioning means for positioning the consumable along the winding dimension before the consumable is wound around the reel, and the reel comprises an engagement means for engaging with the consumable when the reel rotates.

1 . An aerosol generation device configured to heat a consumable comprising tobacco, the device comprising:
 a housing; and   a reel arranged to rotate on an axis of rotation within the housing so as to wind the consumable around the reel, the consumable having a winding dimension along which it is wound around the reel,   the reel comprising:   a positioning means for positioning the consumable along the winding dimension before the consumable is wound around the reel; and   an engagement means for engaging with the consumable when the reel rotates.   
     
     
         2 . An aerosol generation device according to  claim 1 , wherein the reel comprises a reel hole configured to receive an end of the consumable along the winding dimension. 
     
     
         3 . An aerosol generation device according to  claim 2 , wherein the reel hole is a slot, and the consumable is in the shape of a sheet. 
     
     
         4 . An aerosol generation device according to  claim 2 , wherein the reel hole has an end configured to position the end of the consumable. 
     
     
         5 . An aerosol generation device according to  claim 2 , wherein a side of the reel hole is configured to engage with the consumable when the reel rotates. 
     
     
         6 . An aerosol generation device according to  claim 1 , comprising a heating unit arranged on an inner surface of the housing or an outer surface of the reel. 
     
     
         7 . An aerosol generation device according to  claim 6 , wherein the heating unit comprises one or more heating elements arranged to extend around the axis of rotation of the reel. 
     
     
         8 . An aerosol generation device according to  claim 7 , wherein the heating unit comprises a plurality of heating elements separated from one another along the axis of rotation of the reel. 
     
     
         9 . An aerosol generation device according to  claim 1 , comprising a flow channel between an inner surface of the housing and an outer surface of the reel, the flow channel being configured to allow flow of an aerosol generated from the consumable. 
     
     
         10 . An aerosol generation device according to  claim 9 , wherein the housing comprises an insertion hole configured to allow the consumable to be inserted into the flow channel. 
     
     
         11 . An aerosol generation device according to  claim 1 , comprising a protrusion and a guide groove configured to guide movement of the protrusion between a plurality of positions, wherein one of the protrusion and the guide groove is formed on the housing and the other of the protrusion and the guide groove is formed on the reel. 
     
     
         12 . An aerosol generation device according to  claim 11 , wherein the guide groove comprises a first path which extends around the axis of rotation of the reel, and wherein, when the reel rotates, the protrusion is guided along the first path between a start position and an end position. 
     
     
         13 . An aerosol generation device according to  claim 12 , wherein the guide groove comprises a second path which extends along the axis of rotation of the reel between an attached position and a detached position, and wherein the housing and the reel are configured to be attached to or detached from each other by guiding the protrusion along the second path. 
     
     
         14 . An aerosol generation device according to  claim 13 , wherein the attached position of the second path is between the start position and the end position of the first path. 
     
     
         15 . An aerosol generation device according to  claim 11 , wherein, for each of the plurality of positions, the position is an end or a corner of the guide groove. 
     
     
         16 . An aerosol generation device according to  claim 11 , wherein, for each of the plurality of positions, the aerosol generation device comprises a respective position indicator configured to indicate when the protrusion is at the position.
