The chamber is configured to be releasably inserted into the device through an opening in the device. This allows the chamber to be removed from the device and cleaned between consecutive uses of the device. ## Claims ### Claim 1 A portable aerosol-generating device for receiving an aerosol-generating substance, the device comprising: a chamber arranged to receive an aerosol-generating substance, the chamber configured to be connected to a mouthpiece via a fluid passageway; an aerosol-generating unit configured to generate an aerosol from the aerosol-generating substance for a user to inhale in use; and a fluid tube configured to be releasably inserted into the fluid passageway, wherein the chamber is configured to be releasably inserted into the device through an opening in the device, and wherein an end of the fluid tube is configured to dislodge the chamber. ### Claim 2 (depends on 1) The device according to claim 1, wherein the opening is arranged in the aerosol-generating unit and the chamber is configured to be releasably inserted into the aerosol-generating unit through the opening. ### Claim 3 (depends on 1) The device according to claim 1, wherein the opening is configured to be closed. ### Claim 4 (depends on 1) The device according to claim 1, wherein the chamber is configured to receive the aerosol-generating substance through the opening. ### Claim 5 (depends on 1) The device according to claim 1, wherein the chamber comprises an opening. ### Claim 6 (depends on 1) The device of claim 1, wherein the fluid tube is configured to be releasably inserted into the fluid passageway through the opening in the aerosol-generating device. ### Claim 7 (depends on 1) The device according to claim 1, wherein a length of the fluid tube is greater than a length of the fluid passageway. ### Claim 8 (depends on 1) The device according to claim 1, further comprising at least one sealing means to seal between the end of the fluid tube and the fluid passage, or, between the end of the fluid tube and the chamber. ### Claim 9 (depends on 1) The device according to claim 1, wherein the chamber is configured to be removed from the aerosol-generating device by using the fluid tube to dislodge the chamber through the opening in the device. ### Claim 10 (depends on 1) The device according to claim 1, wherein the fluid tube comprises a low heat conductive material whose heat conductivity is less than a conductivity of a material from which the chamber is made. ### Claim 11 (depends on 1) The device according to claim 1, further comprising an induction heater having an electromagnetic inductor surrounding or positioned next to the chamber. ### Claim 12 (depends on 11) The device according to claim 11, wherein the chamber comprises a susceptor. ### Claim 13 (depends on 1) The device of claim 1, further comprising the mouthpiece. ### Claim 14 A method of releasably inserting a chamber into an aerosol-generating device, the method comprising the steps of: providing an aerosol-generating device comprising an opening; releasably inserting the chamber through the opening in the device, wherein the chamber is configured to receive an aerosol-generating substance into the aerosol-generating device; and releasably inserting a fluid tube into a fluid passageway, wherein the fluid passageway is configured to connect the chamber with a mouthpiece, wherein the end of the fluid tube is configured to dislodge the chamber.
