The specific embodiment
Further describe below in conjunction with the dust arrester of the drawings and specific embodiments vacuum cleaner of the present invention:
As shown in Figure 3, separating plate 120 of the present invention is arranged on the centre position of the casing 110 of dust arrester, and suction inlet 112 is arranged above separating plate 120, sucks the air that contains impurity by suction inlet 112.There is the guiding dust to flow to the guide hole 122 of 114 li of dirt pockets that casing 110 bottoms form on the separating plate 120.Be provided with adverse current at the downside of guide hole 122 from guide hole 122 a distance and prevent portion 124.Therefore, the impurity that moves down by guide hole 122 is not that straight line descends, but along separating plate 120, descends by spirality.Above-mentioned adverse current prevents portion 124 on separating plate 120, after prolonging downwards by the beginning part 123 of guide hole 122, again by horizontal direction prolong form.
From another viewpoint, above-mentioned adverse current prevents portion 124, comes down to the part of guide hole 122, on the separating plate along below form spirality, the end part of guide hole 122 and its end nuzzles up.
In addition, above-mentioned guide hole 122 also can be to be formed downwards by spirality by separating plate, and the such structure in fact structure with shown in Figure 3 is identical.
Separating plate 120 of the present invention is made up of a pair of semicircular plate 120a, 120b, sees in the plane, be circular on the whole, and a pair of semicircular plate 120a, 120b is that the center can be rotated with the transverse axis that core forms.Above-mentioned transverse axis 120h is by casing 110 mid portion supports, and a pair of semicircular plate is supported by the boss 116 of casing medial surface, can not rotate downwards, keeps level.Simultaneously, casing 110 is turned around, the pair of semicircular shaped plate is rotated open, pour out the foreign matters such as dust in the downside dirt pocket.
