[0023] According to requirements, the communication positions of the first flow guide pipe 4 and the second flow guide pipe 18 with the converging cylinder box 1 are located at the upper cylinder wall of the converging cylinder box 1, so as to prevent the dust and dirt in the converging cylinder box 1 from flowing back when the suction is stopped; the end of the first cylinder cavity away from the driving gear 19 is communicated with the air inlet of the dust collecting box 13 through the vertical pipe 16, so as to facilitate the falling of the particles in the first cylinder cavity into the dust collecting box 13; the ports of the first flow guide pipe 4 and the second flow guide pipe 18 communicating with the converging cylinder box 1 are closer to the vertical pipe 16 than the other ports, as shown in the accompanying drawings, so that the inclination direction of the first flow guide pipe 4 and the second flow guide pipe 18 is kept in the overall suction direction, avoiding the occurrence of turbulence and ensuring smooth suction.
