Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
Non-for limiting the scope of the present invention.
Noise reduction range hood as shown in Figure 1, Figure 2, Figure 3 shows, including body 1 and exhaust fume collecting hood 2；Be provided with in described body 1 into
Mouth 4 and flue；Described smoke inlet 4 and the denoising draught fan of flue it is communicated with in described exhaust fume collecting hood 2；Described denoising draught fan includes
Casing, described casing internal comprises axial flow blower, and the side of described casing is wind inlet, and opposite side is wind outlet, and described wind enters
The outside encirclement of mouth has noise reduction ring 5, and described noise reduction ring 5 is deadener, the structure that the outlet of described wind is reducing, the described wind of reducing
Outlet is two-layered steel plates, comprises steel plate gap 7, comprise deadener in steel plate gap 7 between two-layered steel plates.
Described two-layered steel plates is divided into inner layer steel plate and outer layer plate, comprises the nut of welding, also comprise in the middle part of inner layer steel plate
Extrusion screw 8, extrusion screw 8 through outer layer plate, being internally located in nut of extrusion screw 8, extrusion screw 8 rotate time
Wait, the change of steel plate gap 7 size can be driven.Extrusion screw 8 rotates, and the distance of the extrusion screw 8 entrance in nut can be entered
The small adjustment of row, can make nut drive inner layer steel plate to move, and therefore distance can be adjusted, and can conveniently change the when of adjustment
