Embodiment

Accompanying drawing has represented structure of the present invention and embodiment, and the below further describes each details of embodiment more by reference to the accompanying drawings.

This particulate catches the blowback circulator, a change of current chamber that is surrounded by housing 4 and substrate 6 20 is arranged, and there is one by

uniform blade

7,8,9 etc. the change of current is indoor, 10 groups of all-in-one-piece rotating inlet passages 11 of sleeve of blade (the present embodiment is 6 blades), curved surface cover plate 12 and a side opening, the two ends of described sleeve 10 are socketed on tubular axis 18 with its substrate 6 one, and the two ends of sleeve 10 rely on tubular axis 18 rotations.

When motor is started shooting air-breathing, when air enters from left side filter bay assembly 2, particulate in atmosphere catches on filter bay assembly 2, air is from guide through hole 14 along rotating inlet passage 11 with when the through motor of suction tude 5, because of guide through hole 14 epimere deflection counter clockwise direction openings, air inlet will promote blade counterclockwise rotates rotating inlet passage 11.Exhaust 1 simultaneously tangentially enters change of current chamber 20 rotations in the counterclockwise direction.exhaust gas particulate is gone out toward the right guide through hole 15 and is captured on filter bay assembly 3, forward the right to from the left side when rotating inlet passage 11, to fixed left and right pilot hole 14 on

substrate

6, 15 and

filter bag

2, 3, the instantaneous exchange of completing intake and exhaust, former left side guide through hole 14 and filter bag 2 become exhaust by air inlet, the particulate that catches during former left side filter bag 2 air inlet turns back in atmosphere, the particulate that guide through hole 15 filter bags 3 in former the right catch when exhaust will be brought into engine combustion with air inlet, the every rotation half cycle of rotating inlet passage 11, filter bag 2, just in time blowback is once for 3 particulates that catch, rotating inlet passage 11 rotating circulatings like this, just can complete the PM particulate and catch the blowback circulating effect.

What need to further illustrate is:
