The specific embodiment

Referring to a kind of upright vacuum cleaner shown in the accompanying drawing 1～2, this dust catcher has two stage cyclone separator-first order cyclone separator 1 and is positioned at the second level cyclone separator 2 in the first cyclone separator downstream.First order cyclone separator 1 and second level cyclone separator 2 are arranged up and down.

First order whirlwind divides device 1 to have an outer cylinder body 11, and the sidewall of outer cylinder body 11 is provided with an air inlet 111 of tangentially arranging, outer cylinder body 11 is the upper and lower opening structure.The lower bottom part of outer cylinder body 11 is provided with a lid 12, and inside is provided with a mesh filter mantle 13.The inner bottom part that the inside of outer cylinder body 11 forms first order cyclone separating chamber 112, outer cylinder body 11 forms first order dust storage chamber 14.

Second level cyclone separator 2 comprises the shell 21 of establishing 5 second level whirlwind tubes 22 in one, and each second level whirlwind tube 22 forms second level cyclone separating chamber 23.Between second level cyclone separating chamber 23 and the first order cyclone separating chamber 112 by gas channel 3 mutually gas be communicated with.The top of shell 21 is provided with a loam cake 24, and loam cake 24 is provided with 5 hollow guide pillars 25 that connect loam cake 24, and these hollow guide pillars 25 are inserted in respectively in 5 second level whirlwind tubes 22, and it can play the effect of water conservancy diversion and exhaust simultaneously.The below of second level whirlwind tube 22 also has the second level dust storage chamber 26 of a flare, and the thin ash after each second level cyclone separating chamber 23 separates all drops in the second level dust storage chamber 26.As shown in the figure, second level dust storage chamber 26 is installed in the outer cylinder body 11 and with first cyclone separating chamber 112 and separates fully, and the gap between second level dust storage chamber 26 and the mesh filter mantle 13 forms the above-mentioned gas channel of mentioning 3.
