Abstract

The invention provides a dust collector air path assembly and cleaning equipment. The dust collector air path assembly mainly comprises a first cyclone assembly, a second cyclone assembly and a filtering assembly. The second cyclone assembly is provided with a concave space. Air flow sequentially flows through the first cyclone assembly, the second cyclone assembly and the filtering assembly; an air inlet path is short and the air inlet and outlet efficiency is high; and the space structure of a dust collector is more compact, so that the occupied space of the dust collector air path assemblyand the cleaning equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner air path assembly and cleaning equipment. Background technique [0002] The working principle of the cyclone separator is the rotational movement caused by the tangential introduction of the airflow. When the particles are rotated at high speed in the airflow, the centrifugal force is much greater than the gravity, and the greater the speed, the greater the centrifugal sedimentation velocity obtained by the particles. When Solid particles enter the hammer-shaped cylinder from the tangential direction with the gas and rotate in the cylinder. At this time, the airflow collides with the wall of the device, and the particles hit the tube wall and rotate down to achieve the purpose of separating solids and gases. A vacuum cleaner using a cyclone separator is known, and after the cyclone separator is separated, the separation effect is further improved by the c...
