Aerosol provision device

Abstract

An aerosol provision device for generating aerosol from aerosol-generating material includes a body and a receptacle configured to receive at least part of an article having aerosol-generating material. The body has an opening communicating with the receptacle. The device further includes a cover mechanism. The cover mechanism includes a cover member arranged to selectively at least partially cover the opening. The cover member is arranged to move relative to the body between a relatively open position in which at least part of an article is able to be inserted through the opening and a relatively closed position in which at least part of an article is prevented from being inserted through the opening. The cover mechanism further includes an actuating member arranged to move relative to the body and a gear mechanism arranged to move the cover member upon movement of the actuating member.

 an actuating member arranged to move relative to the body; and 
 a gear mechanism arranged to move the cover member upon movement of the actuating member. 
   
     
     
         2 . The aerosol provision device of  claim 1 , wherein the actuating member is arranged to at least one of rotate, pivot and translate relative to the body. 
     
     
         3 - 4 . (canceled) 
     
     
         5 . The aerosol provision device of  claim 1 , wherein the gear mechanism comprises an actuating toothed portion on the actuating member. 
     
     
         6 . The aerosol provision device of  claim 5 , wherein the gear mechanism comprises a cover toothed portion on the cover member and wherein movement of the actuating member relative to the body causes the cover member to move as motion is transmitted between the actuating toothed portion and the cover toothed portion. 
     
     
         7 . The aerosol provision device of  claim 6 , comprising a gear arranged to intermesh with the actuating toothed portion and the cover toothed portion, wherein motion is transmitted from the actuating toothed portion to the toothed portion via the gear. 
     
     
         8 . The aerosol provision device of  claim 7 , wherein the gear comprises a first gear segment and a second gear segment and wherein the first gear segment is arranged to intermesh with the actuating toothed portion and the second gear segment is arranged to intermesh with the cover toothed portion. 
     
     
         9 . The aerosol provision device of  claim 8 , wherein the first gear segment drives the second gear segment. 
     
     
         10 . (canceled) 
     
     
         11 . The aerosol provision device of  claim 8 , wherein the first gear segment and the second gear segment differ in at least one aspect to provide a gear ratio. 
     
     
         12 . The aerosol provision device of  claim 6 , wherein the actuating toothed portion directly intermeshes with the cover toothed portion of the cover member. 
     
     
         13 . The aerosol provision device of  claim 5 , wherein the actuating member comprises a peripheral wall and wherein the actuating toothed portion is on an inner side of the peripheral wall. 
     
     
         14 . The aerosol provision device of  claim 1 , wherein the cover mechanism comprises a guide arranged to guide the movement of the cover member. 
     
     
         15 . The aerosol provision device of  claim 5 , wherein the actuating member comprises a housing portion covering at least part of the body. 
     
     
         16 . The aerosol provision device of  claim 15 , wherein the housing portion comprises a gap through which at least a part of the cover member is arranged to be received. 
     
     
         17 . The aerosol provision device of  claim 16 , wherein the cover member is arranged to be retracted from the gap in the relatively closed position and wherein the cover member is arranged to extend in the gap in the relatively open position. 
     
     
         18 . The aerosol provision device of  claim 16 , wherein the body has a pocket for receiving the at least part of the cover member. 
     
     
         19 . The aerosol provision device of  claim 1 , wherein the actuating member comprises an aperture arranged to receive at least a portion of the article comprising aerosol generating material. 
     
     
         20 - 21 . (canceled) 
     
     
         22 . The aerosol provision device of  claim 6 , wherein the cover member comprises a first cover member and a second cover member and wherein the actuating toothed portion is arranged to transmit motion to the cover toothed portion of the first cover member and to the cover toothed portion of the second cover member. 
     
     
         23 . The aerosol provision device of  claim 22 , wherein the actuating toothed portion comprises a first actuating toothed portion arranged to transmit motion to the cover toothed portion of the first cover member and a second actuated toothed portion arranged to transmit motion to the cover toothed portion of the second cover member. 
     
     
         24 . The aerosol provision device of  claim 22 , wherein the first cover member and the second cover member are configured to interface in the relatively closed position. 
     
     
         25 . An aerosol provision system comprising the aerosol provision device of  claim 1 ; and an article comprising aerosol-generating material.
