Gas can radially expand after entering the first screen pipe 610 in the first screen pipe 610, so can will be in air
Most of impurity stays in the first screen pipe 610, and air is flowed out by the strip stomata 611 in outside again.From the first screen pipe 610
Aggregation generates higher air pressure in gap of the air of middle outflow between the first screen pipe 610 and the second screen pipe 620, so
It can be escaped to avoid the impurity in the first screen pipe 610.Then air enters back into the second screen pipe 620, and in the process second
Screen pipe 620 can be with retention part impurity.Then air enters back into third screen pipe 630, due on third screen pipe 630 pair into
The diameter of vent hole 631 is less than the diameter of main air through hole 621 on the second screen pipe 620, therefore third screen pipe 630 can be right
The impurity that second screen pipe 620 does not retain is filtered.Air is filtered after entering third screen pipe 630 by third
The upper end of pipe 630 is flowed out, and is finally passing through air outlet 811.The filter assemblies 600 that the present embodiment uses, using tubular structure, energy
Enough filter the impurity for including in air in inner cylinder 500, while air flow resistance is small, enable air to quickly through.
Further, in the present embodiment, the inner space of 610 cross section of the first screen pipe is in 8 fonts, two strip gas
Hole 611 is connected to the most narrow place of the inner space of 610 cross section of the first screen pipe.So so that in the first screen pipe 610, position
The impurity in air can be preferably locked in the space of 611 both sides of strip stomata, and then effectively impurity is avoided to pass through outside
Strip stomata 611 escapes into outside the first screen pipe 610.
The foregoing is merely the section Examples of the present invention, are not intended to restrict the invention, for art technology
