The invention discloses an efficient cyclone separation device for a dust remover, which comprises a
barrel body and a filter arranged inside the
barrel body, wherein an air inlet communicated with the inside of the
barrel is formed on one side of the upper end of the barrel body in tangential direction of the outer wall; the cross section of the outer wall of an air intake way at the upper end of the barrel body, communicated with the air inlet, is
helical; and a plurality of air intake guide vanes are evenly arranged inside the air intake way in the circular direction. According to the efficient
cyclone separation device for the dust remover, the cross sectional area is gradually reduced from the air inlet to the inside to facilitate the increasement of the tangential speed of the
airflow inside the air intake way along with the reduction of the cross sectional area, so as to increase the separation efficiency of an outer eddy side; the air intake guide vanes are arranged inside the air intake way and evenly distributed in the circular direction to facilitate the conversion of the axial speed of the
airflow to the tangential speed, reduce the loss of energy of axial downwards speed of an inner eddy and improve the suction power of the dust remover; and therefore, the efficient
cyclone separation device for dust remover has the advantages of high efficiency and less
power loss and can effectively improve the suction power of a dust remover motor.
