Abstract

Claims (45)

1 . A charger for charging an aerosol-generating device, the charger comprising:

a housing defining a cavity configured to receive the aerosol-generating device to be charged, the cavity having an opening;

at least one electrical contact disposed in the cavity; and

a cover comprising a plurality of moveable elements actuatable between an open position and a closed position, each of the moveable elements having an inner surface facing the cavity when in the closed position,

wherein at least a portion of the inner surface of at least one of the moveable elements of the cover defines a profiled engagement member having a leading edge and a trailing edge, and

wherein the profiled engagement member slopes into, or towards, the cavity when the respective moveable element is in the closed position, the slope increasing in a direction from the leading edge to the trailing edge of the profiled engagement member.

2 . The charger according to claim 1 , wherein each of the plurality of moveable elements comprises a profiled engagement member sloping into, or towards, the cavity when the respective moveable element is in the closed position, the slope increasing in the direction from the leading edge to the trailing edge of the profiled engagement member.

3 . The charger according to claim 1 ,

wherein the cover further comprises an actuating plate rotatable with respect to the charger housing, and

wherein rotation of the actuation plate actuates the plurality of moveable elements from the open position to the closed position.

4 . The charger according to claim 1 , wherein the cover further comprises an iris mechanism and the plurality of moveable elements form part of the iris mechanism.

5 . The charger according to claim 1 , wherein the cover further comprises between 2 and 6 moveable elements.

6 . The charger according to claim 1 , wherein, in the closed position, the moveable elements do not overlap.

7 . The charger according to claim 1 , wherein the profiled engagement member is configured to urge the aerosol-generating device received in the cavity into engagement with the at least one electrical contact when the plurality of moveable elements are actuated from the open position to the closed position.

8 . The charger according to claim 1 , wherein the profiled engagement member is a cam surface, and a top surface of the aerosol-generating device received in the cavity is a cam rider.

9 . The charger according to claim 1 ,

wherein, in actuating between the open position and the closed position, the plurality of moveable elements move in an actuating plane, and

wherein the profiled engagement member slopes out of the actuating plane.

10 . The charger according to claim 1 , further comprising an actuation member and a means to actuate the plurality of moveable elements of the cover in response to manipulation of the actuation member by a user of the charger.

11 . The charger according to claim 10 , wherein the actuation member is a rotatable disc or a slider, and the means to actuate the plurality of moveable elements of the cover is a mechanical linkage between the actuation member and the cover.

12 . The charger according to claim 10 , wherein the actuation member is a button or switch, and the means to actuate the plurality of moveable elements of the cover comprises an electric motor and a mechanical linkage between the electric motor and the cover.

13 . The charger according to claim 10 , further comprising an aerosol-generating device release mechanism configured to apply a force to the aerosol-generating device received in the cavity in a direction of the cavity opening when the plurality of moveable elements are in the closed position.

14 . An aerosol generating system, comprising:

a charger; and

an aerosol-generating device,

the charger comprising:

a housing defining a cavity configured to receive the aerosol-generating device to be charged, the cavity having an opening,

at least one electrical contact disposed in the cavity, and

a cover comprising a plurality of moveable elements actuatable between an open position and a closed position, each of the moveable elements having an inner surface facing the cavity when in the closed position,

wherein at least a portion of the inner surface of at least one of the moveable elements of the cover defines a profiled engagement member having a leading edge and a trailing edge,

wherein the profiled engagement member slopes into, or towards, the cavity when the respective moveable element is in the closed position, the slope increasing in a direction from the leading edge to the trailing edge of the profiled engagement member, and

wherein, when the aerosol-generating device is received in the cavity, the profiled engagement member is configured to urge the aerosol-generating device into engagement with the at least one electrical contact when the cover is in the closed position.

15 . A method of using an aerosol-generating system,

the aerosol-generating system comprising:

a charger and an aerosol-generating device,

the charger comprising:

a housing defining a cavity configured to receive the aerosol-generating device to be charged, the cavity having an opening,

at least one electrical contact disposed in the cavity, and

a cover comprising a plurality of moveable elements actuatable between an open position and a closed position, each of the moveable elements having an inner surface facing the cavity when in the closed position,

wherein at least a portion of the inner surface of at least one of the moveable elements of the cover defines a profiled engagement member having a leading edge and a trailing edge, and

wherein the profiled engagement member slopes into, or towards, the cavity when the respective moveable element is in the closed position, the slope increasing in a direction from the leading edge to the trailing edge of the profiled engagement member; and

the method comprising:

inserting the aerosol-generating device into the cavity of the charger when the cover is in the open position; and

moving the cover from the open position to the closed position,

wherein, in the closed position, the profiled engagement member of the cover urges the aerosol-generating device into engagement with the at least one electrical contact.
