As shown in fig. 1 to 10, an embodiment of the present invention provides a dust suction apparatus including:

a handle assembly configured to provide a point of application for a user;

the motor assembly is connected to the handle assembly;

the floor brush is connected to the handle assembly;

the dust cup assembly is connected to the handle assembly and comprises a cup body 1, a bottom cover 2, a separator 3, a dust storage part 4 and a dust blocking part 5, the bottom cover 2 is detachably connected to the bottom of the cup body 1, the separator 3 is connected to the inside of the cup body 1, a first dust storage cavity 11 is formed between the separator 3 and the cup body 1, the dust storage part 4 is detachably connected to the separator 3, a second dust storage cavity 41 is formed inside the dust storage part 4, and the dust blocking part 5 is arranged in the first dust storage cavity 11 and connected with the dust storage part 4;

the separator 3 comprises a separation cone 31 and a filter screen 32 connected to the separation cone 31, the dust storage part 4 is detachably connected to the separation cone 31, and the filter screen 32 is in contact with the dust blocking part 5.

According to the dust collection equipment provided by the embodiment of the invention, the motor component is started, a vacuum or negative pressure state is formed in the motor component, so that the outside air is driven to wrap impurities such as dust, hair and the like into the dust cup component, the gas-solid separation is realized through the separator 3 and the dust blocking piece 5, and the clean gas formed after the separation is discharged to the outside environment through the motor component, so that the surface to be cleaned is cleaned. Form first ash storage chamber 11 between separator 3 and the cup 1, store up the inside second ash storage chamber 41 that forms of ash spare 4, the gas-solid carries out first gas-solid separation at high-speed rotation in first ash storage chamber 11, gets into the separation awl 31 of separator 3 through the filter screen 32 of separator 3, and high-speed rotation carries out the secondary separation in separation awl 31, carries out twice separation to the gas-solid and can effectively improve separation efficiency.
