Between spacing be gradually reduced from the host shell medial surface where auxiliary water conservancy diversion noise reduction body toward host shell center position.
This programme cross section auxiliary water conservancy diversion noise reduction body triangular in shape can put open the fraction inside oil smoke machine host
Vortex reduces the collision between vortex, while reducing noise, leads the air-flow along inside, keeps air-flow more smooth, improves oil
Smoke machine air draught effect.
Preferably, being equipped with the second hollow lumen in auxiliary water conservancy diversion noise reduction body, assist setting on the lateral surface of water conservancy diversion noise reduction body
There are several noise reduction holes being connected with the second hollow lumen, sound-absorbing material in also is equipped in second hollow lumen.
When the pneumatic noise and electromagnetic noise of blower fan group are propagated outward, when by auxiliary water conservancy diversion noise reduction body, through noise reduction hole,
A portion noise is absorbed by the intracorporal interior sound-absorbing material of auxiliary water conservancy diversion noise reduction, reaches secondary reduction function of noise.
Preferably, the lateral surface of host shell is equipped with host sound-absorbing material.Host sound-absorbing material to pneumatic noise and
Electromagnetic noise further absorbs, and reach reduces function of noise three times.
Preferably, host sound-absorbing material is externally provided with host panel.
Preferably, major flow noise reduction body is connected by bolt with host shell.
Preferably, auxiliary water conservancy diversion noise reduction body is connected by bolt with host shell.
The beneficial effects of the present invention are: noise can not only be reduced, and the kitchen ventilator of kitchen ventilator air draught effect can be improved
Water conservancy diversion sound-absorbing solid noise reduction system.
