The separating member 14 is accommodated in the dust cup body 12, the separating member 14 is used for separating dust and impurities in the airflow, and the filtered dust and impurities are left in the dust collecting cavity. It should be noted that, since the separating member 14 is not a main utility model of the present application, the specific configuration of the separating member 14 is not described herein.

The filter element 16 is disposed on a side of the separating element 14 facing the motor assembly 30, and the airflow filtered by the separating element 14 is further filtered by the filter element 16, and the airflow filtered by the filter element 16 flows into the motor assembly 30. In this manner, the airflow is further filtered by the filter element 16 after being filtered by the separating element 14, thereby improving the cleanliness of the airflow entering the motor assembly 30.

The motor assembly 30 is connected to one axial end of the dirt cup assembly 10 and includes a motor housing 32, a motor body 34, and a filter assembly 36. Specifically, motor casing 32 includes motor casing end wall and motor casing lateral wall, and motor casing end wall and dirt cup subassembly 10 interval set up, and the motor casing lateral wall extends to the dirt cup lateral wall with dirt cup main part 12 from the edge of motor casing end wall and is connected, and motor casing lateral wall encircles the motor casing end wall periphery and forms the motor with the common definition of motor casing end wall and hold the chamber, and the central point of motor casing end wall puts the gas outlet 321 of seting up the intercommunication motor and holding the chamber.
