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.

First claim

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.
