Aerosol provision device

Abstract

An aerosol provision device for generating an aerosol from aerosol-generating material, the device has an article receptacle defining a heating zone to receive at least a portion of an aerosol-generating article including aerosol-generating material. The article receptacle is disposed at a first end of the device. The device also has a filter cavity arranged to receive at least a portion of a filter element, the filter cavity disposed at a second end of the device, the second end being opposite to the first end. A flow passage is provided between the article receptacle and the filter cavity.

1 . An aerosol provision device for generating an aerosol from aerosol-generating material comprising:
 an article receptacle defining a heating zone configured to receive at least a portion of an aerosol-generating article comprising aerosol-generating material, the article receptacle being disposed at a first end of the device;   a filter cavity arranged to receive at least a portion of a filter element, the filter cavity disposed at a second end of the device, the second end being opposite to the first end; and   a flow passage between the article receptacle and the filter cavity.   
     
     
         2 . The aerosol provision device of  claim 1 , wherein the flow passage is elongate. 
     
     
         3 . The aerosol provision device of  claim 1 , comprising a tubular member defining the flow passage. 
     
     
         4 . The aerosol provision device of  claim 1 , wherein the cross-sectional area of the flow passage is less than the cross-sectional area of the heating zone defined by the article receptacle. 
     
     
         5 . The aerosol provision device of  claim 1 , wherein the cross-sectional area of the flow passage is less than the cross-sectional area of the filter cavity. 
     
     
         6 . The aerosol provision device of  claim 1 , comprising a shoulder at an internal end of the filter cavity. 
     
     
         7 . The aerosol provision device of claim any of elaims  1 , comprising a converging portion from the article receptacle to the flow passage. 
     
     
         8 . The aerosol provision device of  claim 1 , wherein the flow passage extends from the article receptacle to the filter cavity. 
     
     
         9 . The aerosol provision device of  claim 1 , wherein the flow passage extends along a longitudinal axis of the device. 
     
     
         10 . The aerosol provision device of  claim 1 , comprising a heating element. 
     
     
         11 . The aerosol provision device of  claim 10 , wherein the heating element protrudes in the heating zone. 
     
     
         12 . The aerosol provision device of  claim 10 , wherein the heating element defines at least part of the heating zone. 
     
     
         13 . The aerosol provision device of  claim 12 , wherein the article receptacle comprises the heating element. 
     
     
         14 . An aerosol provision system comprising:
 an aerosol provision device for generating an aerosol from aerosol-generating material comprising:
 a receptacle defining a heating zone configured to receive at least a portion of an aerosol generating element comprising aerosol-generating material, the receptacle being disposed at a first end of the device, 
 a cavity arranged to receive at least a portion of a filter element, the cavity disposed at a second end of the device, the second end being opposite to the first end, and 
 a flow passage between the receptacle and the cavity; and 
   a consumable comprising:
 an aerosol generating element, and 
 a filter element. 
   
     
     
         15 . A consumable for an aerosol provision device comprising:
 an aerosol generating element comprising aerosol generating material; and   a filter element; wherein the aerosol generating element and the filter element are arranged to be separably insertable into the aerosol provision device.   
     
     
         16 . The consumable of  claim 15 , wherein the aerosol generating element and the filter element are discrete elements. 
     
     
         17 . The consumable of  claim 15 , wherein the aerosol generating element and the filter element are separable. 
     
     
         18 . The consumable of  claim 17 , wherein the consumable comprises a juncture between the aerosol generating element and the filter element, the aerosol generating element and the filter element being arranged to be separated along the juncture. 
     
     
         19 . The consumable of  claim 18 , wherein the juncture comprises a region of weakness.
