Compared with prior art, the invention has the advantages that：
(1) extractor fan of the invention carries out assembling by the upper cartridge body and lower box body that connect up and down and forms monoblock type knot
Structure need to only use an exhausting motor to carry out exhausting in bottom, simplify equipment, maintain easily maintenance, reduce cost；
(2) extractor fan of the invention includes the first interconnected middle chamber and the second middle chamber and mutually interconnects
Logical baffling cavity and reflux cavity, under the action of exhausting motor, the gas part in burner hearth is up walked, and a part is down
It walks, the gas up walked carries out baffling after the first middle chamber by baffling cavity, is then circulated to by reflux cavity
Exhausting tube side-by-side under lower air extracting box goes out, and the air-flow to walk downward is directly over the second middle chamber flow to exhausting tube side-by-side and go out,
Effective discharge of the gas in the burner hearth of reflow soldering is realized in this way, even if minimal amount of steam is in lower air extracting box
Liquid is condensed into be attached on lower air extracting box inner wall, it, can be along lower air extracting box when the scaling powder of liquid is accumulated to a certain extent
Inner wall will not damage the pcb board for being located at position among entire extractor fan toward downstream in exhaust column mouth；
(3) the exhausting baffle that sets of the present invention can design different width as needed, so as to balance upper air extracting box and
The exhausting amount of lower air extracting box so that exhausting effect is more preferable.
