## Abstract

An aerosol provision device is provided. The device has an axis and comprises, at a first end, an end member at least partially surrounded by an outer cover. The end member and the outer cover together define an end surface of the aerosol provision device, wherein the end member defines a recess which is positioned away from the end surface in the direction of the axis and is covered by the outer cover.

## Claims

### Claim 1

An aerosol provision device having an axis and comprising:
a power source; and
an end member, at a first end, at least partially surrounded by an outer cover, the end member and the outer cover together defining an end surface of the aerosol provision device, wherein the end member defines a recess which is positioned away from the end surface in the direction of the axis and is covered by the outer cover, the recess configured to interrupt capillary flow of water.

### Claim 2 (depends on 1)

The aerosol provision device of claim 1, wherein the recess extends fully around the axis to provide a continuous recess.

### Claim 3 (depends on 1)

The aerosol provision device of claim 1, wherein the device comprises an electrical component located on the other side of the recess from the end surface.

### Claim 4 (depends on 3)

The aerosol provision device of claim 3, wherein the electrical component is a socket and the end member delimits a through hole for access to the socket.

### Claim 5 (depends on 1)

The aerosol provision device of claim 1, wherein the end member comprises a second recess extending around the axis, and the device further comprises a resilient member arranged in the second recess.

### Claim 6 (depends on 5)

The aerosol provision device of claim 5, wherein the second recess is arranged further away from the end surface than the recess.

### Claim 7 (depends on 1)

The aerosol provision device of claim 1, wherein the end member comprises an attachment component arranged further away from the end surface than the recess, wherein the attachment component engages the outer cover.

### Claim 8 (depends on 1)

The aerosol provision device of claim 1, wherein the recess has a depth dimension of greater than about 0.5 mm.

### Claim 9 (depends on 1)

The aerosol provision device of claim 1, wherein the recess has a depth dimension of less than about 4 mm.

### Claim 10 (depends on 1)

The aerosol provision device of claim 1, wherein the recess has a width dimension of greater than about 0.5 mm.

### Claim 11 (depends on 1)

The aerosol provision device of claim 1, wherein the recess has a width dimension of less than about 10 mm.

### Claim 12 (depends on 1)

The aerosol provision device of claim 1, wherein at least a portion of the recess is positioned away from the end surface by a distance of about 1 mm to about 15 mm.

### Claim 13 (depends on 1)

The aerosol provision device of claim 1, further comprising at least one inductor coil configured to generate a varying magnetic field for heating a susceptor.

### Claim 14 (depends on 1)

An aerosol provision system, comprising:
an aerosol provision device according to claim 1; and
an article comprising aerosol generating material.

### Claim 15

A method for protecting electrical components and a power source of an aerosol provision device from water ingress, the method comprising:
positioning the electrical components and the power source for protection in a portion of the device spaced apart from an end of the device; and
providing an air gap between otherwise generally abutting surfaces using a recess, wherein the air gap is positioned between the end of the device and the electrical components, the air gap preventing flow of water by capillary action from the end of the device to the electrical components.

### Claim 16 (depends on 15)

The method of claim 15, wherein providing an air gap comprises providing an air gap greater than about 0.5 mm between the otherwise generally abutting surfaces.
