The specific embodiment
Embodiment: in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 with Figure 5 shows that a kind of specific embodiment of the utility model motor of dust collector noise-reducing structure.
At first as shown in Figure 1, it comprises and is located at vacuum chamber 1, the motor room 2 in the dust catcher body and is positioned at their partition walls 3 between the two; 2 front portions, described motor room are provided with motor air inlet 4, and partition wall 3 is provided with lattice-shaped air inlet 5; Have a cavity 6 between described barrier shape air inlet 5 and the motor air inlet 4, the sectional area of this cavity 6 is greater than motor air inlet 4, simultaneously also greater than barrier shape air inlet 5.
Further combined with Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the described dust catcher body of present embodiment is buckled by loam cake 16 and low shell 17 and forms, described partition wall 3 takes shape on the low shell 17, and also form motor bearing 18 on the low shell 17, this motor bearing 18 with buckle motor on it and partly cover 19 and surround motor room 2, horizontally disposed in this motor room 2 have motor 21, and the central lines of the axis of this motor 21 and low shell 17.
