Aerosol provision device

Abstract

An aerosol provision device has a body and an airflow path arrangement through the body; the airflow path arrangement including a receptacle defining a heating zone arranged to receive at least a portion of an article having aerosol generating material. The device also has a fluid chamber in the body; and a fluid passage between the airflow path arrangement and the fluid chamber.

1 . An aerosol provision device comprising:
 a body;   an airflow path arrangement through the body;   the airflow path arrangement comprising a receptacle defining a heating zone arranged to receive at least a portion of an article comprising aerosol generating material;   a fluid chamber in the body; and   a fluid passage between the airflow path arrangement and the fluid chamber.   
     
     
         2 . The aerosol provision device of  claim 1 , wherein the fluid chamber is separated from the airflow path arrangement by a wall. 
     
     
         3 . The aerosol provision device of  claim 2 , wherein the fluid passage comprises a slot in the wall. 
     
     
         4 . The aerosol provision device of  claim 2 , wherein the receptacle comprises a receptacle wall defining the wall, and wherein the fluid passage comprises a receptacle wall aperture which extends through the receptacle wall. 
     
     
         5 . The aerosol provision device of  claim 2 , wherein the airflow path arrangement comprises a flow path member at one end of the receptacle. 
     
     
         6 . The aerosol provision device of  claim 5 , wherein the flow path member comprises a flow path member wall defining the wall, wherein the fluid passage comprises a flow path member wall aperture which extends through the flow path member wall. 
     
     
         7 . The aerosol provision device of  claim 5 , wherein the flow path member extends from the receptacle at a juncture, and wherein the fluid passage is at the juncture. 
     
     
         8 . The aerosol provision device of  claim 7 , wherein an end of the flow path member overlaps an end of the receptacle and wherein a gap is defined between part of the flow path member and part of the receptacle at the overlap 
     
     
         9 . The aerosol provision device of  claim 8 , wherein the flow path member comprises an expanded portion at the overlap. 
     
     
         10 . The aerosol provision device of  claim 1 , further comprising a cavity in the receptacle support in fluid communication with the fluid chamber. 
     
     
         11 . The aerosol provision device of  claim 10 , wherein the receptacle comprises an outer side, and a sensor on the outer side of the receptacle. 
     
     
         12 . The aerosol provision device of  claim 11 , wherein the sensor is on a diametrically opposite side of the receptacle to the fluid passage. 
     
     
         13 . The aerosol provision device of  claim 12 , comprising a fluid impermeable sheath around at least part the receptacle. 
     
     
         14 . An aerosol provision device comprising:
 a receptacle defining a heating zone arranged to receive at least a portion of an article comprising aerosol generating material;   a flow path member at one end of the receptacle, the receptacle and flow path member defining at least part of an airflow path through the device; and   a condensate collection cavity in the housing in fluid communication with the airflow path.   
     
     
         15 . An aerosol provision device comprising:
 a housing,   a receptacle defining a heating zone arranged to receive at least a portion of an article comprising aerosol generating material; and   a fluid impermeable sheath around at least part the receptacle.   
     
     
         16 . The aerosol provision device of  claim 15 , wherein the receptacle comprises an outer side, and a sensor on the outer side of the receptacle. 
     
     
         17 . The aerosol provision device of  claim 16 , wherein the sensor is between the sheath and the receptacle. 
     
     
         18 . The aerosol provision device of  claim 16 , wherein the sheath defines a layer on the outer side of the receptacle. 
     
     
         19 . The aerosol provision device of  claim 16 , wherein the sheath is formed of a thermally reactive material. 
     
     
         20 . An aerosol provision system comprising an aerosol provision device of  claim 1 , and an article containing aerosol generating material arranged to be at least partially received in the aerosol provision device.
