An exhaust channel 7 is provided on the right side of the dust and gas separation box 1, and a dust collection main unit 8 is installed on the right end of the exhaust channel 7. A hand-held handle 9 is fixedly connected to the lower end of the dust and gas separation box 1, and a dust collecting cup 3 is installed at the lower end of the dust collecting cup 3 through a threaded groove 101. A dust cup cover 4 is provided at the lower end of the dust collecting cup 3, and a partition 301 is fixedly connected to the inner wall of the dust collecting cup 3. Air is sucked through the vacuum main unit 8, and the air in the dust and gas separation box 1 is sucked out through the suction channel 7, so that the air pressure at the upper end of the dust and gas separation box 1 is lower than the air pressure at the lower end, and then the gas at the lower end is sucked out through the cyclone separation body 11, so that the outside air carrying the dust enters the cyclone separation channel 10 through the dust suction channel 5. The slope of the cyclone separation channel 10 cooperates with the cyclone separation body 11 to make the dust rotate. During the rotation, large particles of dust enter the dust collecting cup 3 through the first dust inlet 302, and small particles of dust enter the dust collecting cup 3 through multiple second dust inlets 303 during the rotation, thereby completing the separation of dust and air without the need for a filter. The device has a simple structure, is easy to use, and is not large in size. It is suitable for cleaning desktops and small places, and has a good cleaning effect.

Since the entire device is in a tilted state at this time, the first dust inlet 302 is at the lowest end. During the rotation, large particles of dust enter the dust collecting cup 3 through the first dust inlet 302, and small particles of dust enter the dust collecting cup 3 through multiple second dust inlets 303 during the rotation, thereby completing the separation of dust and air without the need for a filter. The device has a simple structure, is easy to use, and is small in size. It is suitable for cleaning desktops and small places. It has a good cleaning effect.
