An aerosol-generating system is also provided. ## Claims ### Claim at position 1 -17. (canceled) ### Claim 18 An aerosol-generating device, comprising: a housing defining a cavity configured to receive an aerosol-generating article through an open end of the cavity; and a constricting member connected to the housing and being moveable between an open position and a constricting position to selectively constrict at least a portion of the cavity. ### Claim 19 (depends on 18) The aerosol-generating device according to claim 18, wherein the constricting member is selectively moveable between the open position and the constricting position when the aerosol-generating article is received in the cavity to selectively constrict at least the portion of the cavity. ### Claim 20 (depends on 18) The aerosol-generating device according to claim 18, wherein the constricting member is moveable to selectively constrict the open end of the cavity. ### Claim 21 (depends on 18) The aerosol-generating device according to claim 18, wherein the constricting member is biased towards the constricting position. ### Claim 22 (depends on 18) The aerosol-generating device according to claim 18, further comprising a spring disposed between the housing and the constricting member, wherein the spring is configured to bias the constricting member towards the constricting position. ### Claim 23 (depends on 18) The aerosol-generating device according to claim 18, wherein the constricting member comprises a collar extending around an outside of the cavity of the housing. ### Claim 24 (depends on 18) The aerosol-generating device according to claim 18, wherein the constricting member is slidably connected to the housing such that the constricting member is moveable along a region of a length of the housing. ### Claim 25 (depends on 24) The aerosol-generating device according to claim 24, wherein the housing further comprises a recess configured to receive at least part of the constricting member when the constricting member is in the open position. ### Claim 26 (depends on 18) The aerosol-generating device according to claim 18, wherein the housing comprises a main body and a moveable wall connected to the main body, the moveable wall defining at least part of the open end of the cavity, wherein the moveable wall is moveable between a first position in which the open end has a first minimum diameter and a second position in which the open end has a second minimum diameter that is smaller than the first minimum diameter, and wherein the constricting member is configured to selectively constrict the open end of the cavity by deflecting the moveable wall to the second position. ### Claim 27 (depends on 26) The aerosol-generating device according to claim 26, wherein the moveable wall is biased towards the first position when the constricting member is in the open position. ### Claim 28 (depends on 26) The aerosol-generating device according to claim 26, wherein the moveable wall is resilient and is configured to deflect relative to the main body of the housing to move to the second position by elastic deformation when the constricting member is moved to the constricting position and to return automatically to the first position when the constricting member is moved to the open position. ### Claim 29 (depends on 26) The aerosol-generating device according to claim 26, wherein the moveable wall is connected to the main body of the housing by a hinge about which the moveable wall is moveable between the first position and the second position. ### Claim 30 (depends on 18) The aerosol-generating device according to claim 18, wherein the aerosol-generating device is an electrically heated aerosol-generating device and further comprises an electric heater positioned in the cavity and being configured to heat an aerosol-forming substrate when received in the cavity. ### Claim 31 (depends on 30) The aerosol-generating device according to claim 30, wherein the electric heater comprises one or more external heating elements, one or more internal heating elements, or one or more external heating elements and one or more internal heating elements. ### Claim 32 (depends on 18) An aerosol-generating system, comprising: an aerosol-generating device according to claim 18; and an aerosol-generating article for the aerosol-generating device, the aerosol-generating article comprising an aerosol-forming substrate. ### Claim 33 (depends on 32) The aerosol-generating system according to claim 32, wherein the aerosol-forming substrate comprises a tobacco-containing material comprising volatile tobacco flavour compounds that are released from the substrate upon heating. ### Claim 34 (depends on 32) The aerosol-generating system according to claim 32, further comprising a user interface configured to activate the aerosol-generating system.
