Because the position that the exhaust in circuitous stream is separately passed through is formed with acoustic material 28, is being provided with acoustic material from the circuitous stream that electric blowing machine 1 begins to emit, and can further realize low noiseization thus.
The structure of distinguishing wall 23 is to contact slightly with the shell of electric blowing machine 1, but also the gap can be set, and uses soft gastight material betwixt in the crack, can obtain same effect and effect.If make the gap of distinguishing wall 23 and electric blowing machine 1 less than the gap of the 24, the 2nd next door 25, the 1st next door with electric blowing machine 1, then can strengthen the aeration resistance of distinguishing wall 23 and electric blowing machine 1 gap, make nearly all exhaust become flowing of needed exhaust thus.In the gap that flows into the 24, the 2nd next door 25, the 1st next door and electric blowing machine 1, can obtain same effect and effect.
The capacity of the 1st exhaust outlet 3 and the 2nd exhaust outlet 5 is in the relation of a kind of the 1st exhaust outlet 3 less than the 2nd exhaust outlet 5, particularly be located at the interval area on the 1st outlet the 21, the 1st next door 24 and the electric blowing machine 1, be set to the minimum area of the pressure loss that can not cause the capacity of discharging from the 1st exhaust outlet 3, so can further reduce noise.
As Fig. 2, Fig. 3, shown in Figure 5, distinguish the approximate centre position that wall the 23, the 1st next door 24 and the 2nd next door 25 are formed into electric blowing machine 1 always, do not distinguish fully above it, in the present embodiment, because of the outlet of being located at box body 20 is positioned at the below, so can make the mobile formation u turn of exhaust.Thus, if distinguish fully, natural energy of the present invention obtains better effect.
In the structure of electric blowing machine 1, take whirlwind mode etc. also can obtain same effect and effect without paper bag 10 again.
