• a removable cyclone separation unit arranged in the dust cup;
• and
• a dust scraping device,
• wherein:
• the dust cup and the main machine are arranged on the main body, and the dust scraping device is fixedly mounted at the dust cup and is coupled to the main machine by an engagement slot formed in the dust scraping device and an engagement block formed outside a connection end of a main machine housing of the main machine;
• the dust scraping device comprises:
• a dust scraping member configured as a cylindrical dust scraping ring and having an L-shaped radial section, a transverse portion of the L-shaped radial section extending in a removal direction of the cyclone separation unit, and a vertical portion of the L-shaped radial section extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit;
• a connection base arranged coaxially with the dust scraping ring and fixed to an open portion of the dust cup;
• and
• a dust scraping ring mounting rack arranged coaxially with the dust scraping ring and in the connection base, wherein a side, away from the open portion, of the dust scraping ring mounting rack is fixedly or detachably coupled to the dust scraping ring,
• wherein the dust scraping device is mounted at the dust cup, and the vertical portion is a dust scraping portion and scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.
