Abstract

An aerosol provision device includes a housing delimiting a first opening at a first end of the housing through which to receive aerosol generating material and delimiting a second opening at a second end of the housing. A chamber is positioned between the second opening and the first opening, wherein at least part of the chamber is configured to receive the aerosol generating material. At least one heater is arranged within the housing and configured to heat aerosol generating material received within the chamber thereby to generate an aerosol. An absorbent material for absorbing liquid is provided.

Claims

exact text as granted — not AI-modified
1 . An aerosol provision device, comprising:
 a housing delimiting a first opening at a first end of the housing, through which to receive aerosol generating material, and delimiting a second opening at a second end of the housing;   a chamber positioned between the second opening and the first opening, wherein at least part of the chamber is configured to receive the aerosol generating material;   at least one heater arranged within the housing and configured to heat aerosol generating material received within the chamber thereby to generate an aerosol; and   an absorbent material for absorbing liquid;   wherein, in use, the aerosol is drawn along a flow path through the chamber towards the first opening and the absorbent material is at least partially positioned upstream of the at least part of the chamber configured to receive the aerosol generating material.   
     
     
         2 . The aerosol provision device according to  claim 1 , further comprising a cover movable between a first position in which the second opening is blocked by the cover, and a second position in which the second opening is not blocked by the cover. 
     
     
         3 . The aerosol provision device according to  claim 2 , wherein:
 the cover comprises a recess; and   the absorbent material is arranged at least partially in the recess.   
     
     
         4 . The aerosol provision device according to  claim 2 , wherein, in use, the absorbent material is at least partially positioned between the aerosol generating material and the cover. 
     
     
         5 . The aerosol provision device according to  claim 2 , wherein the cover is detachable from the aerosol provision device. 
     
     
         6 . The aerosol provision device according to  claim 1 , wherein the absorbent material comprises foam, sponge, paper or cellulose acetate. 
     
     
         7 . The aerosol provision device according to  claim 1 , wherein the absorbent material has an absorption capacity of at least 7 grams of water per gram of absorbent material. 
     
     
         8 . The aerosol provision device according to  claim 1 , wherein the absorbent material is at least partially arranged within a section of the chamber. 
     
     
         9 . (canceled) 
     
     
         10 . (canceled) 
     
     
         11 . The aerosol provision device according to  claim 1 , wherein at least a portion of the absorbent material is gas permeable. 
     
     
         12 . (canceled) 
     
     
         13 . The aerosol provision device according to  claim 1 , wherein the absorbent material comprises a through-hole for air to pass through. 
     
     
         14 . The aerosol provision device according to  claim 1 , further comprising an absorbent member which comprises the absorbent material supported by a substrate. 
     
     
         15 . (canceled) 
     
     
         16 . The aerosol provision device according to  claim 1 , further comprising a brush which comprises the absorbent material. 
     
     
         17 . The aerosol provision device according to  claim 1 , wherein the chamber comprises a barrier to separate the aerosol generating material from the absorbent material. 
     
     
         18 . The aerosol provision device according to  claim 1 , further comprising a hydrophobic material arranged within the housing to substantially prevent liquid from leaking out of the aerosol provision device. 
     
     
         19 . The aerosol provision device according to  claim 1 , wherein at least a portion of the chamber is hydrophobic, or comprises a hydrophobic coating, to encourage the liquid to flow towards the absorbent material. 
     
     
         20 . The aerosol provision device according to  claim 1 , wherein at least a portion of the absorbent material is configured to provide a visual indication to indicate that the absorbent material is ready to be replaced or cleaned. 
     
     
         21 . (canceled) 
     
     
         22 . (canceled) 
     
     
         23 . An absorbent member for absorbing liquid in an aerosol provision device, the absorbent member comprising:
 an absorbent material supported by a substrate, wherein the absorbent material is configured to be at least partially received in a chamber or a door of the aerosol provision device adjacent aerosol generating material.   
     
     
         24 - 29 . (canceled) 
     
     
         30 . An aerosol provision device, comprising:
 a housing delimiting a first opening at a first end of the housing, through which to receive aerosol generating material, and delimiting a second opening at a second end of the housing;   a chamber positioned between the second opening and the first opening, wherein at least part of the chamber is configured to receive aerosol generating material;   at least one heater arranged within the housing, configured to heat the aerosol generating material received within the chamber thereby to generate an aerosol; and   a hydrophobic material arranged within the housing to substantially prevent liquid from leaking out of the aerosol provision device;   wherein, in use, the aerosol is drawn through the chamber towards the first opening.   
     
     
         31 . The aerosol provision device according to  claim 30 , further comprising a cover movable between a first position in which the second opening is blocked by the cover and a second position in which the second opening is not blocked by the cover, wherein the hydrophobic material is configured to substantially prevent liquid from leaking past the cover when the cover is arranged in the first position. 
     
     
         32 - 39 . (canceled) 
     
     
         40 . The aerosol provision device according to  claim 30 , further comprising an absorbent material.
