Spiral salient A7 and spiral salient B8 with the same hand of spiral；The spiral salient A7 is along 2 top of upper housing to upper housing 2
Lower part extends, and the spiral salient B8 extends along 3 top of lower case to 3 lower part of lower case, and spiral salient A7 and spiral salient
B8 makes 2 inner wall of upper housing form the helical intake 9 for being connected to air inlet 5 to ash discharging hole 6 with 3 inner wall of lower case.
Wherein, the lower end surface of spiral salient A7 and 2 lower end surface of upper housing are located at same level, the upper end of spiral salient B8
Face and the upper surface of lower case 3 are located at same level；The spiral salient A7 has upper end inclined-plane 10, the spiral salient B8
With lower end inclined-plane 11, the upper end inclined-plane 10 setting parallel or non-parallel with lower end inclined-plane 11；The upper end inclined-plane 10 is under
End inclined-plane 11 constitutes the helical intake 9 for the influence air flow direction being made of 2 inner wall of upper housing and 3 inner wall of lower case.
As shown in figure 3, further, in order to guide air to enter helical intake, the starting point of the helical intake 9 and air inlet
Step A12 is formed at mouth 5.
As shown in figure 4, further, being focused at ash discharging hole for the ease of dust, it is discharged convenient for dust, the helical intake
6 form step B13 at 9 tail end and ash discharging hole.
Further, eddy flow is quickly formed in shell in order to guide air to enter, the air inlet 5 is arranged in upper housing
It 2 tops and is connect along 2 outer wall tangential direction of upper housing with upper housing 2.
As shown in figure 8, in order to adapt to different operating environment and job requirements, the air inlet 5 or/and ash discharging hole 6 are located at
In the first quartile of 3 horizontal cross-section of upper housing 2 or lower case, the second quadrant, third quadrant or/and fourth quadrant.
The air inlet 5 and ash discharging hole 6 be arbitrarily arranged at one respectively, two, three, can be achieved in four-quadrant region it is above-mentioned
Leaching effect, user can match the inlet and outlet mouth of different directions, while the path length of adjustable helical intake according to the actual situation
Degree.
As shown in fig. 6, air inlet screen 14 is provided at the air inlet 5, described for the ease of connecting with air inlet

The present invention operates in such a way: cylinder is negative pressure when engine suction, air and impurity are inhaled into the cyclone type
Air cleaner, air and impurity first pass around the air inlet screen 14 and carry out primary filtration, and bulky impurity is just first arranged
Except in the air for entering the whirlwind air cleaner, air and impurity by primary filtration enter the air inlet 5 into
Row accelerates, and carries out forcibly high-speed screw subsequently into the screw thread air flue 9 on the upper housing 2 and the lower case 3
Rotary motion, the step A12 that spiral salient A7 and the air inlet 5 on the upper housing 2 are formed by mandatory water conservancy diversion,
So that spiral air flow is continued downward spiral movement, and non-interference with the air of the air inlet 5 sucking, guarantee that air inlet is smooth,
Weight impurity bigger than normal can be thrown to inner walls by gravity, rotary centrifugal force by high-speed screw movement simultaneously, and hoard institute
9 bottom of screw thread air flue described in lower case 3 is stated, since the screw thread air flue 9 is communicated to the ash-valve 18, finally hoards institute
The impurity for stating 3 bottom of lower case is taken at the ash-valve 18 by spiral air flow, the spiral salient B8 of the lower case 3 with it is described
Ash discharging hole 6 formed step B13 can stop spiral rotating air-flow continue screw, and by part with impurity air-flow from
Screw becomes the linear motion tangent with the helical intake 9, then the ash-valve by being connected to the helical intake 9
18 exclude；The openings of sizes of the ash-valve 18 is variable, is not easy to be blocked by impurity and user is easy cleaning and maintenance.By
The cyclone centrifugal of the primary filtration of the air inlet screen 14 and the screw thread air flue 9 filters, and also remains on a small quantity in the air of sucking
Small, the small in size impurity of weight, this partial impurities, which is finally absorbed by the filter core 4, carries out refined filtration, and last clean air enters
The pedestal 1 is inhaled into engine.
