The invention relates to an aerosol-generating device comprising a mainbody (10) and a mouthpiece (12). The main body comprises a heating chamber (14) for receiving an aerosol-forming substrate. The mouthpiece is movably connected to the main body. The mouthpiece is configured movable with respect to the main body in a first movement between a first position and a second position. The first position is an operation position of the aero sol-generating device. In the second position, the heating chamber is at least partially exposed. The mouthpiece is configured movable with respect to the main body in a second movement between the second position and a third position. The second movement of the mouthpiece from the second position to the third position is configured to trigger an event.

A mouthpiece for a smoking article, the mouthpiece comprising a smoking article articulation end and a mouthpiece end with a flow path extending therebetween, and wherein the mouthpiece end comprises a lip portion configurable for placing at a space between lips of an individual without pursing.
