DUST SEPARATOR
First Claim
1. A dust separator comprising:
- a shell having a cylindrical tank body and an air inlet channel, said air inlet channel extending in a tangential direction relative to said tank body;
a partitioner mounted in said shell and cooperating with said shell to define a first cyclone chamber therebetween, said first cyclone chamber being in fluid communication with said air inlet channel, said partitioner having an upper cup part and a lower part that is disposed below said upper cup part, said upper cup part defining a top opening and a cup inner space and being formed with at least one cup-wall through-hole that is in fluid communication with said first cyclone chamber and said cup inner space, said lower part defining a dust collecting space that is isolated from said first cyclone chamber and said cup inner space; and
a multi-cone unit supported on said upper cup part to cover said top opening of said upper cup part and including a plurality of cones that extend through said cup inner space into said dust collecting space, each of said cones having an upper end portion that is formed with a tangent channel-forming notch having two opposite sides, said upper end portion having a circumferentially-extending segment and a tangentially from said circumferentially-extending segment, said circumferentially-extending segment having an end section that defines an end face, said end face of said end section being disposed at one of said sides of said tangent channel-forming notch, said tangentially-extending segment having an inner face that confines the other of said sides of said tangent channel-forming notch, said tangentially-extending segment of each of said cones sidewisely joining said end section of said circumferentially-extending segment of an adjacent one of said cones, each of said cones defining a lower opening in fluid communication with said dust collecting space, and a second cyclone chamber in fluid communication with said lower opening and said tangent channel-forming notch;
wherein an air flow introduced into said first cyclone chamber via said air inlet channel is caused to flow in a helical pattern to thereby result in a first separation of air from dust carried by the air flow; and
wherein the air flow introduced from said first cyclone chamber into said second cyclone chamber via said tangent channel-forming notches of said cones is caused to flow in a helical pattern to result in a second separation of air from dust carried by the air flow.

Abstract
A dust separator includes: a partitioner mounted in a shell and including an upper cup part; and a multi-cone unit supported on the upper cup part and including a plurality of cones, each of which has an upper end portion formed with a tangent channel-forming notch and having a circumferentially-extending segment and a tangentially-extending segment. The circumferentially-extending segment has an end face disposed at one side of the tangent channel-forming notch. The tangentially-extending segment has an inner face that confines the other side of the tangent channel-forming notch. The tangentially-extending segment of each of the cones sidewisely joins an end section of the circumferentially-extending segment of an adjacent one of the cones.
