An aerosol provision device including a body having an opening; a chamber in the body arranged to receive at least a portion of an article including aerosol generating material through the opening; and a cover mechanism. The cover mechanism includes a cover member arranged to at least partially cover the opening; and an actuating member arranged to rotate on the body to actuate the cover member. Rotation of the actuating member relative to the body causes the cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening.

The present application is a National Phase entry of PCT Application No. PCT/EP2023/062068 filed May 5, 2023, which claims priority to GB Application No. 2206680.7 filed May 6, 2022, each of which is hereby incorporated by reference in their entirety.
The present invention relates to an aerosol provision device. The present invention also relates to a cover mechanism for an aerosol provision device and an aerosol provision system.
Smoking articles such as cigarettes, cigars and the like burn tobacco during use to create tobacco smoke. Attempts have been made to provide alternatives to these articles that burn tobacco by creating products that release compounds without burning. Examples of such products are heating devices which release compounds by heating, but not burning, the material. The material may be for example tobacco or other non-tobacco products, which may or may not contain nicotine.
In accordance with some embodiments described herein, there is provided an aerosol provision device comprising: a body having an opening; a chamber in the body arranged to receive at least a portion of an article comprising aerosol generating material through the opening; and a cover mechanism comprising: a cover member arranged to selectively at least partially cover the opening; an actuating member arranged to rotate on the body to actuate the cover member; wherein rotation of the actuating member relative to the body causes the cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening.
The cover member may be arranged to linearly translate relative to the body.
The body may comprise a guide arranged to slidably engage with the cover member.
The guide may comprise a track.
The track may comprise a channel.
The guide may comprise at least two parallel channels.
The cover member may comprise a guide element arranged to engage with the guide on the body.
The actuating member may comprise a housing portion covering at least part of the body.
At least part of the body may extend in the housing portion.
The actuating member may at least partially enclose the cover mechanism.
The actuating member may comprise an aperture aligned with the opening arranged to receive at least a portion of an article.
The cover member may be disposed between the body and the actuating member.
The cover member may be arranged to translate in a direction perpendicular to an axis of rotation of the actuating member.
An axis of rotation of the actuating member may be parallel with a longitudinal axis of the chamber.
The axis of rotation of the actuating member may be co-axial with the longitudinal axis of the chamber.
The cover mechanism may comprise a cam arrangement.
The cam arrangement may comprise an elongate cam surface and a cam element engaged by the elongate cam surface.
The elongate cam surface may be linear.
The elongate cam surface may be arcuate.
The cam arrangement may comprise a cam slot defining the elongate cam surface.
The cam slot may be a blind slot.
The cam element may be a pin.
The actuating member may define the elongate cam surface.
The actuating member may define an outer actuating component defining an exposed face and an inner actuating component defining the elongate cam surface.
The outer actuating component may be slidably engaged with the body.
The inner actuating component may be mounted on the outer actuating component.
The inner and outer actuating components may be formed of different materials.
The cam element may be on the cover member.
The cover mechanism may comprise a gear arrangement.
The cover member may be a blade.
The body may comprise an actuating member mount.
The actuating member may be rotatably engaged with the actuating member mount.
The actuating member mount may restrict linear movement of the actuating member relative to the body.
The actuating member may comprise a locating feature in engagement with the actuating member mount.
The actuating member mount may comprise a clip. The clip may be resilient.
The body may comprise a recess behind the clip.
The cover mechanism may comprise a retaining mechanism arranged to releasably retain the actuating member in at least one of the relatively open and the relatively closed position.
The cover member may make sliding contact with the body and actuating member. The sliding contact may be arranged to seal against ingress of debris.
The actuating member may comprise a gripping formation. The gripping formation may be a protrusion. The gripping formation may be a friction surface.
The cover member may fully close the opening in the relatively closed position.
The cover member may be a first cover member and the cover mechanism may comprise a second cover member arranged to selectively partially close the opening.
Rotation of the actuating member relative to the body may cause the second cover member to translate between a relatively open position in which the at least a portion of an article is able to pass through the opening and a relatively closed position in which the at least a portion of an article is prevented from being able to pass through the opening.
In the relatively closed position, the first and second cover members may abut each other.
The body may comprise a second guide arranged to slidably engage with the second cover member.
The second guide may comprise a track.
The track may comprise a channel.
The second guide may comprise at least two parallel channels.
