Aerosol Provision Device

The present application is a National Phase entry of PCT Application No. PCT/EP2023/061991 filed May 5, 2023, which claims priority to GB Application No. 2206678.1 filed May 6, 2022, both of which are hereby incorporated by reference in their entirety.

The present invention relates to an aerosol provision device. The present invention also relates to an aerosol provision system comprising an aerosol provision device and an article comprising aerosol-generating material, and also a cover mechanism for an aerosol provision device.

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; a chamber in the body arranged to receive at least a portion of an article comprising aerosol generating material; and a cover mechanism comprising: a cover member moveable between a relatively open position in which the at least a portion of an article is able to pass into the chamber and a relatively closed position in which the at least a portion of an article is restricted from being able to pass into the chamber; and a channel arranged to guide movement of the cover member, the channel having an open end.

The open end of the channel may communicate with the chamber.

The open end of the channel may communicate with an outer side of the body.

The aerosol provision device may comprise a stop at the open end of the channel.

The stop may comprise a lip or protrusion. The lip or protrusion may be arranged to limit the range of motion of the cover member.

An edge of the stop may at least partially define the open end.

The channel may be a groove. The channel may be on the body. The channel may be on an end surface of the body.

The channel may be linear. The cover member may comprise a guide element received in the channel.

The guide element may comprise at least one of a rib and a pin.

A width of the guide element may substantially correspond to a width of the channel.

A height of the guide element received in the channel may substantially correspond to a depth of the channel.

A profile of the guide element may correspond to a profile of the channel.

The guide element may be slideable in the channel.

The guide element may be movable to at least proximal to the open end

The channel may have first and second open ends.

The first open end of the channel may communicate with the chamber. The second open end of the channel may communicate with a peripheral edge of the body.

A lower side of the cover member may be in sliding contact with the body. The sliding contact may be arranged to at least partially seal against ingress of debris between the cover member and the body.

The channel may be a first channel and the body may comprise a second channel.

The guide element may be a first guide element, and the cover member may comprise a second guide element.

The aerosol provision device may comprise an upstand on the body.

The upstand may be aligned with the channel.

The upstand may be parallel with the channel.

A height of the upstand may substantially correspond with a thickness of the cover member.

The upstand may be arranged to at least partially confine debris to a region of the housing containing the opening.

An edge of the cover member may move adjacent to the upstand.

The upstand may be arranged to slidably contact a side of the cover member.

The cover mechanism may comprise an actuating member arranged to rotate on the body to actuate the cover member. Rotation of the actuating member relative to the body may cause the cover member to move between the relatively open position and the relatively closed position.

Rotation of the actuating member relative to the body may cause the cover member to translate between the relatively open position and the relatively closed position.

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 or each cover member may be arranged to linearly translate relative to the body.

The actuating member may comprise a housing portion covering at least part of the body.

The housing portion may comprise a peripheral wall.

The open end of the channel may be spaced from the peripheral wall.

At least part of the body may extend in the housing portion.

The body may comprise a recess on a peripheral side of the body.

The channel may communicate with the recess.

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 actuating member mount may at least partially extend in the recess.

The actuating member mount may be spaced from the open end.

The actuating member may at least partially enclose the cover mechanism.
