The cover mechanism includes: 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.

Abstract: 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.

Abstract: An aerosol provision device for generating an aerosol from aerosol-generating material includes a housing and a heating assembly. The heating assembly includes a heating chamber arranged to receive at least a portion of an article having aerosol generating material, an inductor coil encircling at least part of the heating chamber, and a coil support on which at least a portion of the inductor coil is positioned. The coil support includes a locating feature which engages with the housing to locate the heating assembly in position within the housing.

Abstract: An aerosol provision device includes a body and a chamber for receiving at least a portion of an article including aerosol generating material. The body has an opening communicating with the chamber. An actuating member is arranged to rotate about the body, and a cover member is arranged to pivot about the body. Rotation of the actuating member relative to the body causes the cover member to pivot between an open position in which the at least a portion of an article is able to pass through the opening and a closed position in which the opening is fully covered.

Abstract: An aerosol provision device has a body, a heating assembly defining a heating chamber arranged to receive at least a portion of an article including aerosol generating material, and an air passage extending between the heating chamber and the air inlet. A check valve is arranged to selectably close the air passage from the air inlet to the heating chamber.

Abstract: An aerosol provision device generates an aerosol from aerosol-generating material. The device has a tubular member defining a heating chamber. The heating chamber is configured to receive an article containing aerosol-generating material. The tubular member has an inwardly projecting stop to limit insertion of the article. An aerosol generating system is also described, the system having an article that is receivable in the heating chamber of the device.

Abstract: An aerosol generating device for generating an aerosol from aerosol-generating material. The device has a magnetic field generator with an inductor coil configured to generate a varying magnetic field. The device also has a heating element that is heatable by penetration with the varying magnetic field. The heating element defines a heating zone configured to receive at least a portion of an article including aerosol-generating material. The heating element is fixed relative to the inductor coil. The inductor coil encircles a first portion of the heating zone such that the first portion is heated at least predominantly by inductive heating. A second portion of the heating zone is free from being encircled by any inductor coil so that the second portion of the heating zone is heated predominantly by conductive heating.
