the front cover 6 is arranged at the front end of the lower cover plate 4, and the center of the front cover is provided with a jack for installing the air guide pipe 5;
the dust storage bin 3 is an interlayer area formed among the inner wall of the shell 1, the inner wall of the front cover 6 and the outer wall of the cyclone cone 2;
one end of the air guide pipe 5 is arranged in the jack, the other end of the air guide pipe is connected with the shell 1 and the edge of the lower cover plate 4, and the interior of the air guide pipe 5 is communicated with the air inlet duct;
