42. The aerosol generating device of claim 41, wherein the aerosol generating device is configured to prevent removal of the container and/or atomizing mechanism from the upper housing.
43. An aerosol generating system, characterized in that it comprises:

    a liquid source storing a liquid matrix;

    The aerosol generating device includes a casing, the casing includes a proximal end and a distal end opposite along the length direction: the casing includes an upper casing and a lower casing arranged in sequence along the length direction; wherein,

    the lower housing is adjacent to the distal end and houses at least one of a circuit board and a battery cell;

    The upper casing is close to the proximal end, and the upper casing is provided with:

    a container at least partially defining a receiving cavity into which a source of liquid is removably received; and,

    a vibratable element configured to vibrate to atomize the liquid substrate to generate an aerosol;

    The upper housing is configured to be immovable or removable relative to the lower housing.
