According to the collection assembly of dust 100 of the embodiment of the present invention, by multiple second blade 122 and multiple first blade 112 are staggeredly arranged in the circumferential, can make to form multiple high-voltage dc between the first annular ring 110 and the second annular ring 120, improve the efficiency of dust collection of collection assembly of dust 100.In addition, multiple first blade 112 and multiple second blade 122 have the effect of rectification to the air-flow through collection assembly of dust 100, thereby enhance airflow homogeneity, and then resistance when reducing the admission pressure of air-flow and flow, thus the noise produced when reducing air current flow.
According to one embodiment of present invention, the beeline between the first annular ring 110 and the second annular ring 120 is more than or equal to 2mm.In other words, on the first annular ring 110, the spacing of any point and the second annular ring 120 is more than or equal to 2mm.Thus, air is breakdown, electric discharge or the phenomenon of short circuit can effectively to prevent collection assembly of dust 100 from use occurring, thus improves the job stability of collection assembly of dust 100, ensure that safety coefficient and the dust removing effects of collection assembly of dust 100.Preferably, the first adjacent blade 112 and the distance at the second blade 122 interval are 2-40mm.Thus, air is breakdown, the phenomenon of electric discharge can to prevent collection assembly of dust 100 from use occurring further, thus further increasing the job stability of collection assembly of dust 100, ensure that safety coefficient and the dust removing effects of collection assembly of dust 100.
In an alternate exemplary of the present invention, as shown in Figure 6, the first blade 112 along the thickness in the first annular ring 110 circumferential direction for being greater than 0.5mm, i.e. d1 > 0.5mm.As shown in Figure 8, the first blade 112 is greater than 5mm along the width on the axial direction of the first annular ring 110, i.e. h1 > 5mm.As shown in figure 12, the second blade 122 is greater than 0.5mm along the thickness in the circumferential direction of the second annular ring 120, i.e. d2 > 0.5mm.As shown in figure 14, the second blade 122 is greater than 5mm along the width on the axial direction of the second annular ring 120, i.e. h2 > 5mm.Thus, the clean-up effect of collection assembly of dust 100 can be ensured, improve the purification efficiency of collection assembly of dust 100, simplify the structure of collection assembly of dust 100, make the structure of collection assembly of dust 100 compacter, reasonable.

Further, as shown in Fig. 5, Fig. 6, Fig. 8 and Figure 10, the first outer ring 111 is connected to the upper end of the radial outside of the first blade 112, and the upper surface of the radial outside of the first blade 112 is higher than the upper surface of its radially inner side.In other words, on the axial direction of the first annular ring 110, the width of the radial outside of the first blade 112 is greater than the width of its radially inner side.Thus, the compactness of collection assembly of dust 100 is further increased.Further, in example as shown in figure 5 and figure 7, the lower surface of multiple first blade 112 is all concordant and in the same plane.Thus, the structure of collection assembly of dust 100 can be made more neat, compact.
In example as shown in fig. 5-10, the first annular ring 110 can also comprise: the first inner ring 114.Wherein, the first inner ring 114 is connected to the radially inner side of multiple first blade 112.Thus, the structure of the first annular ring 110 can be made more stable.Further, as shown in Fig. 5-Fig. 6, the first annular ring 110 also comprises: the first stiffening ring 115.Wherein, the first stiffening ring 115 is connected on the inner surface of the first inner ring 114 by multiple the first reinforcement 116 circumferentially distributed.Thus, the structural strength of the first annular ring 110 can be strengthened further.
Similarly, in the such as example shown in Figure 11-Figure 15, the lower surface of the radial outside of the second blade 122 is higher than the lower surface of its radially inner side.In other words, on the axial direction of the second annular ring 120, the width of the radial outside of the second blade 122 is greater than the width of its radially inner side.Second outer ring 121 is connected to the radial outside of the second blade 122.When the second annular ring 120 coordinates with the first annular ring 110, the area that the first adjacent blade 112 is corresponding with the second blade 122 can be increased further, and then increase the area of the high-voltage dc formed between the first adjacent blade 112 and the second blade 122, thus, the efficiency of dust collection of collection assembly of dust 100 can be improved.Meanwhile, the compactness of collection assembly of dust 100 can also be improved further.Further, in example as shown in figure 5 and figure 7, the upper surface of multiple second blade 122 is all concordant and in the same plane.Thus, the structure of collection assembly of dust 100 can be made more neat, compact.
