1. A partition skirt device, configured to be mounted in a cyclone separation unit of a cleaning apparatus, the partition skirt device having an annular structure, wherein the partition skirt device comprises: an annular inner ring; and an annular skirt body comprising: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring, a diameter of the edge part being larger than a diameter of the root; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and the collapsing part being configured as a long strip structure extending along a radial direction of the skirt body, wherein along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body, and is recessed relative to the skirt body on a second side
an annular skirt body comprising:
a root connected to the inner ring;
an edge part arranged at an end of the skirt body away from the inner ring, a diameter of the edge part being larger than a diameter of the root; and
a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and the collapsing part being configured as a long strip structure extending along a radial direction of the skirt body,
wherein along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body, and is recessed relative to the skirt body on a second side surface of the skirt body;
on the first side surface of the skirt body, a size of a portion of the collapsing part protruding in the thickness direction from the skirt body gradually decreases from the root to the edge part.
