Specific embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of metal exhaust fan, it is characterised in that：
It includes tubular air duct 1, and wind turbine 2 is equipped in air duct 1, is covered on the air outlet 3 of air duct 1 and is equipped with non-return piece 4；It is described
Non-return piece 4 at least three pieces are set, non-return piece 4 connect fixation by mounting ring 5 with air duct 1；It is fixed to be equipped in the mounting ring 5
Position hole 6, fixed screw are spirally connected across location hole 6 with air duct 1, and mounting ring 5 is connect fixation with air duct 1；The mounting ring 5 is wrapped
Panel 51 and the boss 52 set on 51 side of panel are included, 52 lower section of boss is provided with mounting hole 7, and fixed screw passes through non-return piece 4
It is hinged with mounting hole 7, and non-return piece 4 is placed on panel 51；There are two the settings of mounting ring 5, is symmetrically mounted on air duct 1
Inside.
The non-return piece 4 includes upper wind shield 41, middle wind shield 42 and lower wind shield 43, on the top margin of middle wind shield 42
