Aerosol provision device

Abstract

An aerosol provision device including a body having an opening; a chamber in the body arranged to receive at least a portion of an article including aerosol generating material through the opening; and a cover mechanism. The cover mechanism includes a cover member arranged to at least partially cover the opening; and an actuating member arranged to rotate on the body to actuate the cover member. Rotation of the actuating member relative to the body causes the cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening.

1 . An aerosol provision device comprising:
 a body having an opening;   a chamber in the body arranged to receive at least a portion of an article comprising aerosol generating material through the opening; and   a cover mechanism comprising:   a cover member arranged to selectively at least partially cover the opening; and   an actuating member arranged to rotate on the body to actuate the cover member;   wherein rotation of the actuating member relative to the body causes the cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening.

         4 . An aerosol provision device as claimed in  claim 3 , wherein the cover member comprises a guide element arranged to engage with the guide on the body. 
     
     
         5 . An aerosol provision device as claimed in  claim 1 , wherein the actuating member comprises an aperture aligned with the opening arranged to receive at least a portion of an article. 
     
     
         6 . An aerosol provision device as claimed in  claim 1 , wherein the cover member is disposed between the body and the actuating member. 
     
     
         7 . An aerosol provision device as claimed in  claim 1 , wherein the cover member is arranged to translate in a direction perpendicular to an axis of rotation of the actuating member. 
     
     
         8 . An aerosol provision device as claimed in  claim 1 , wherein the cover mechanism comprises a cam arrangement. 
     
     
         9 - 11 . (canceled) 
     
     
         12 . An aerosol provision device as claimed in  claim 1 , wherein the cover member makes sliding contact with the body and actuating member. 
     
     
         13 . An aerosol provision device as claimed in  claim 1 , wherein the cover member is a first cover member and the cover mechanism comprises a second cover member arranged to partially close the opening. 
     
     
         14 . (canceled) 
     
     
         15 . A cover mechanism for an aerosol provision device, the cover mechanism comprising:
 a body having an opening arranged to receive at least a portion of an article comprising aerosol generating material;   
       a cover member arranged to selectively at least partially cover the opening; and 
       an actuating member arranged to rotate on the body to actuate the cover member; 
       wherein rotation of the actuating member relative to the body causes the cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening. 
     
     
         16 . An aerosol provision device comprising:
 a body;   a chamber in the body arranged to receive at least a portion of an article comprising aerosol generating material;   the body having an opening communicating with the chamber; and   a cover mechanism comprising:   a cover member arranged to selectively at least partially cover the opening;   an actuating member arranged to rotate on the body to actuate the cover member;   wherein rotation of the actuating member relative to the body causes the cover member to move between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening; and   a retaining mechanism arranged to releasably retain the actuating member in at least one of the relatively open position and the relatively closed position.   
     
     
         17 . An aerosol provision device as claimed in  claim 16 , wherein the retaining mechanism is biased into a retention condition when the actuating member is moved into the at least one of the relatively open position and the relatively closed position. 
     
     
         18 . An aerosol provision device as claimed in  claim 16 , wherein the retaining mechanism comprises a recess and a protruding element arranged to protrude in the recess in the at least one of the relatively open position and the relatively closed position. 
     
     
         19 . An aerosol provision device as claimed in  claim 18 , wherein the recess comprises a ramp and the protruding element is arranged to slide along the ramp when entering or leaving the recess. 
     
     
         20 . An aerosol provision device as claimed in  claim 19 , wherein the protruding element contacts the ramp over less than 20% of the range of motion between the relatively open and the relatively closed positions. 
     
     
         21 . An aerosol provision device as claimed in  claim 18 , wherein the protruding element is arranged to be biased radially outwardly. 
     
     
         22 . (canceled) 
     
     
         23 . An aerosol provision device as claimed in  claim 16 , wherein the retaining mechanism is a first retaining mechanism and wherein the aerosol provision device further comprises a second retaining mechanism arranged to releasably retain the actuating member in the other of the relatively open position and the relatively closed position. 
     
     
         24 . A cover mechanism for an aerosol provision device, the cover mechanism comprising:
 a body having an opening arranged to receive at least a portion of an article comprising aerosol generating material;   a cover member arranged to selectively at least partially cover the opening;   an actuating member arranged to rotate on the body to actuate the cover member;   wherein rotation of the actuating member relative to the body causes the cover member to move between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening; and   a retaining mechanism arranged to releasably retain the actuating member in at least one of the relatively open position and the relatively closed position.   
     
     
         25 . An aerosol provision system comprising the aerosol provision device of  claim 1 ; and an article comprising aerosol-generating material. 
     
     
         26 . An aerosol provision system comprising the aerosol provision device of  claim 16 ; and an article comprising aerosol-generating material.
