The short transverse of body 1 extends and is arranged at the guide duct 13 in cup 1, the inner hollow of guide duct 13, in every guide duct 13
Filtering wind post 22 is equipped with, filtering wind post 22 passes through in the open insertion guide duct 13 on the top of cup 1, and filtering wind post 22 is outer
At intervals with formation positioned at air channel between the two between the madial wall of side wall and guide duct 13.
Reference picture 2 and Fig. 4, the side that guide duct 13 is offsettingly located inside cup 1.In one embodiment, guide duct
Formed with the dust collecting space 14 for collecting dust between 13 lateral wall and the madial wall of cup 1.So as to the inside quilt of cup 1
Guide duct 13 is divided into the filter space in guide duct 13 and the dust collecting space outside guide duct 13 14, by reasonable
Space configuration cause the inner space of cup 1 arrange advantages of simple.
Reference picture 1, Fig. 2 and Fig. 3, the air intake led to respectively inside every guide duct 13 is offered in the side wall 11 of cup 1
Mouth 12.So that the air for being mingled with other solid particles such as dust, impurity drawn via suction head of suction cleaner can pass through
The filter space that air inlet 12 enters inside guide duct 13, the bottom of the closer cup 1 of air inlet 12.
Reference picture 2, Fig. 4 and Fig. 5,13 cylindrical structure of guide duct, air inlet 12 relative to guide duct 13 axis
Biasing is configured so that air intake direction and the madial wall of guide duct 13 is tangent.As shown in Figures 4 and 5, it is mingled with solid particle
Air-flow enters the bottom of guide duct 13 via air inlet 12, because the madial wall of air inlet 12 and guide duct 13 is tangent, air-flow
Enter after guide duct 13 under the guiding of the madial wall of guide duct 13, smooth excessive into along guide duct 13 of the direction of advance of air-flow
Madial wall rotates in a circumferential direction.
Reference picture 6, the top of guide duct 13, which is offered towards dust collecting space 14, gets rid of grey mouth 131.So that quality compared with
Big solid particle can be collected from getting rid of to get rid of in dust collecting space 14 at grey mouth 131 under the influence of centrifugal force.
Reference picture 2, the middle and upper part of filtering wind post 22 are circumferentially provided with screen pack 221, and shape is opened wide at the top of filtering wind post 22
Into the air outlet 222 having towards the external world.Be equipped with filtering wind post 22 middle and upper part screen pack 221 and columnar structured lead
Airduct 13 so that be mingled with the air-flow of solid particle from air inlet 12 enter the inside of guide duct 13 after can be in filtering wind post 22
Lateral wall and guide duct 13 madial wall between air channel in formed spiral escalation flow direction.
Referring again to Fig. 6, double helix filter assemblies 2 include：Keep out the wind component 23, and the component 23 that keeps out the wind includes being inserted into two
Wind isolation board 231 between individual air outlet 222 and the deep bead 232 located at the end of wind isolation board 231, the both wings point of deep bead 232
It is not oppositely arranged with two air outlets 222.The wind isolation board 231 of component 23 of keeping out the wind can get rid of grey mouth 131 cut-off by two and open, and prevent
The solid particle thrown away in one of guide duct 13 is dumped into another guide duct 13.Deep bead 232 can stop from
The rotation that grey mouth 131 throws away dust is got rid of, prevents the rotation from driving the dust fallen into dust collecting space 14 to kick up again.
In one embodiment of the application, in the short transverse of cup 1, wind isolation board 231 and deep bead 232 are contour,
And the height of wind isolation board 231 and deep bead 232 and the height of the filtering wind post 22 are in a preset ratio.It is specifically, described pre-
If ratio can be 1 to 3.The wind isolation board 231 and deep bead 232 can be it is integrally formed can also be connected together
's.The wind isolation board 231 and deep bead 232 being combined together according to T-shape, can also be according to the combination of " ten " font
Together.In a preferred embodiment, wind isolation board 231 and deep bead 232 being combined together according to T-shape.
Shown in reference picture 7, double helix filter assemblies 2 can also include：Fixed disk 21, it is fixed in the top of filtering wind post 22
Portion；The component 23 that keeps out the wind is fixed in the lower surface of fixed disk 21, and the top for filtering wind post 22 causes air-out through fixed disk 21
Mouth 222 communicates with the external world.In a preferred embodiment, 21 structure in disk form of fixed disk.
It should be noted that in the application other embodiment, the component 23 that keeps out the wind, which can also be fixed in this, has double helix
The other positions of the dirt cup of dust and gas isolating construction, for example, the component 23 that keeps out the wind can be affixed with guide duct (13).
Further, the top of fixed disk 21 is provided with filter core 3.So that the air of fine particle is remained from air outlet
After 222 outflows, the air after the filtering of filter core 3 becomes cleaner, reduces the secondary pollution to caused by environment.
Further, when filtering wind post 22 is inserted into the inside of cup 1 by the opening on the top of cup 1, wind post is filtered
22 bottom is tightly connected with the bottom wall of cup 1, and the top of guide duct 13 is tightly connected with the lower surface of fixed disk 21, so that
The bottom that wind post 22 must be filtered is sealed by the bottom wall of cup 1, and the top of guide duct 13 is sealed by the lower surface of fixed disk 21.
Sealed specifically, can be in contact with the bottom wall of cup 1 by filtering the bottom of wind post 22, or by sealing ring come close
Envelope.In a preferred embodiment, filter wind post 22 to be arranged concentrically with guide duct 13, so that when air-flow circulates in air channel
Turbulent flow can be reduced, flow velocity is improved, further increases filter efficiency.
During work, due to being provided with filtering wind post 22 in guide duct 13, the middle and upper part of filtering wind post 22 is provided with screen pack 221,
The top of filtering wind post 22 is provided with air outlet 222, and the madial wall of air inlet 12 and guide duct 13 is tangent, so that via
