Abstract
The utility model provides a kind of axial flow blower with low noise blade, and problem to be solved is that existing axial flow blower can produce larger noise in relatively quiet place；It is tubular bellows to be characterized in that the housing, electric machine support is provided with bellows inwall, electric machine support upper end is provided with motor, impeller is provided with the output shaft of motor, the impeller is made up of at least three blades, if being provided with dry fish scale shape projection on the windward side of each blade；The utility model has the advantages that in the case where not changing axial flow blower volume, keep motor rotations, fixed ventilation is obtained within the unit interval and make blower fan in the operating condition caused noise control in relatively low scope.The utility model also has the characteristics that simple in construction, easy to operate, practical.
Description
Technical field：
Blower technology field is the utility model is related to, specifically a kind of axial flow blower with low noise blade.
Background technology：
What common workshop and office space open air exhaust was selected is all axial flow blower, although axial flow blower relative noise compared with
It is small, but relatively quiet place still shows larger.Generally selected to reduce air-flow caused noise, industry when passing through blower fan
The ventilation of acquisition fixation while major diameter blade coordinates Low speed electric motor to ensure low noise within the unit interval.But by
Be not suitable for using in specific place in the reason for its volume.
The content of the invention
The utility model provides a kind of axial flow blower with low noise blade.
What the purpose of this utility model was realized in：It includes：Housing, it is characterized in that：The housing is tubular bellows,
Electric machine support is provided with bellows inwall, electric machine support upper end is provided with motor, and impeller is provided with the output shaft of motor, described
Impeller is made up of at least three blades, if being provided with dry fish scale shape projection on the windward side of each blade.
One end of housing is provided with toroidal wind collecting unit.
Protection network is provided with toroidal wind collecting unit.
The fish scale shape projection is waveform.
The utility model has the advantages that in the case where not changing axial flow blower volume, motor rotations are kept, in unit
It is interior obtain fixed ventilation and make blower fan in the operating condition caused noise control in relatively low scope.The utility model
Also have the characteristics that simple in construction, easy to operate, practical.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 side view.
Embodiment
Embodiment 1
Referring to Fig. 1 ~ 2, housing 1 is tubular bellows, and electric machine support 2 is provided with bellows inwall, and electric machine support upper end is set
There is motor 3, impeller 4 is provided with the output shaft of motor, the impeller is made up of four blades 5, on the windward side of each blade
If it is provided with dry fish scale shape projection 6.
One end of housing is provided with toroidal wind collecting unit 7.
