As preferably, described fan induced draught mouthpiece comprises the external frame part-annular body consistent with semi-circular parts Internal periphery, the fascia edge of described part-annular body is provided with around the part-annular body upper edge of a week, described part-annular body stretches in semi-circular parts from the top of semi-circular parts, and described upper edge is clipped between semi-circular parts and fore shell.
As preferably, the middle part of described part-annular body is provided with inner ring, described centrifugal fan towards the side of fore shell by interior loop mapping, described inner ring up/down perforation.
As preferably, described fore shell and back cover are EPP shell.
As preferably, described fan induced draught mouthpiece is the parts of ABS material.
As preferably, described centrifugal fan and blower fan fixed base are connected and fixed by screw.
As preferably, described blower fan fixed base is connected with blower fan clamp ring through back cover by bolt.
As preferably, connect by being stained with colloid between described semi-circular parts and fan induced draught mouthpiece.
As preferably, described fore shell and back cover are sealed and matched.
Beneficial effect:
After the utility model adopts technique scheme, by arranging semi-circular parts at back cover towards the one side of fore shell, fan induced draught mouthpiece is clipped between fore shell and semi-circular parts, centrifugal fan is located at the inside cavity that semi-circular parts and fan induced draught mouthpiece surround, blower fan fixed base is fixed on the one side that back cover deviates from fore shell, then be fixedly connected with blower fan fixed base through back cover by centrifugal fan, blower fan clamp ring is located between back cover and centrifugal fan, blower fan clamp ring is fixedly connected with blower fan fixed base, fan induced draught mouthpiece covers the top at semi-circular parts, this configuration reduces fabricating cost, assemble very convenient, during work, noise can be effectively reduced, do not affect air output simultaneously.
