Hollow rotating shaft drives the axial-flow type atomising mechanism during this machine work, fan, the rotation of water pump vane synchronous high-speed, fan and impeller abrasive disc produce negative pressure oil smoke are sucked the oil smoke suction inlet in purification pipe, enter purification pipe, water after cleaner is filtered in the rotation of water pump vane synchronous high-speed is pressed into the water pump guide vane wheel through pipe fitting and input hole, in ostium enters hollow rotating shaft, because pressure and centrifugal force make water spray into narrow annular channel between abrasive disc and impeller abrasive disc and the gasket ring from the hollow rotating shaft flow-out hole, because the water layer that the viscosity contraction pushes out is thinner, stick on the wall of abrasive disc, circumferential speed and inertia force all increase with radius on the abrasive disc of rotation at a high speed, water adhesion is broadened by narrow on the wall of abrasive disc, by thick attenuation, by low speed at a high speed, to the edge slippage, the fan blade of impeller abrasive disc not only increases the blast of suction, and increased the whirlpool and mixed efficient, moisture film as thin as a wafer is broken atomizing in air-flow, mist droplet granularity is very little can be greater than water film thickness, density is very big, circumferential speed with the abrasive disc edge flies to the purification pipe tube wall, with the oil smoke that sucks, flue dust collision cooling, make oil smoke, steam condenses into drop, because droplet speed is very big, can not sneak into air-flow, oil droplet and flue dust and droplet one superhigh speed fly on the tube wall of purification pipe, its current that rotate at a high speed flow down along tube wall, because centrifugal force part current get rid of in the U-lag of arc guiding gutter, being affixed on tube wall along guiding gutter flows down, can not sneak into air-flow and fly to exhaust outlet, the blast that air-flow after the cleaning is produced by fan is depressed into exhaust outlet along deflector and discharges, and has finished the cleaning oil smoke, flue dust makes the process of water and flow separation.The current of rotation, air-flow flow out along the deflector of the geomantic omen separating opening tangential direction of purification pipe, because blast descends the liquid level at separating opening place, geomantic omen, the liquid level of both sides rises, the sump oil that current, air-flow and rectangle oil baffle gather on forcing and bubbling through the water column enters the oil extraction mouth of pipe, flow into sewer, the flue dust sediment deposition and be flowed to tank at the bottom of end-of-the-pipe, recirculated water has been finished the separation process of removing sump oil, flue dust silt and current again because the suction of water pump flows to cleaner again and recycles.In finding observation window, after the recirculated water muddiness, control draining-off sewage silt by valve.When water level descends and the float-controlled valve automatic water-supply that joins of running water pipe, when float-controlled valve leaks, enter the oil extraction mouth of pipe and overflow.After opening the valve of cleaning agent case bottom, cleaning agent mixes with water, after cleaner, pipe fitting, input hole, water pump, axial-flow type atomising mechanism fully mix in the water periodic duty cleaning robot inside.Because the air-flow after cleaning is depressed into exhaust outlet, be provided with the air returning valve that it departs from center of gravity in its mouthful, when shutdown, stop return air, when start, increase exhaust resistance, make the interior blast of case slightly high, part air-flow is from air curtain hole that return air inlet is depressed into backwind tube and return air hole every cigarette wind hole and kitchen range top return air arm, oil smoke suction inlet place suction is bigger, and other place's suction is slightly little, air-flow from from the air curtain hole to the ejection of oblique below forms air curtain through the guide plate guiding, guide plate can be adjusted the direction of air-flow, stop that oil smoke wafts and oil smoke is blowed to the oil smoke suction inlet, oil smoke waft rise to the exhaust fume collecting hood top board by every cigarette wind hole from three top blasts to the oil smoke suction inlet, the air-flow of veneer reduces contacting of oil smoke and petticoat pipe, the condensing of minimizing greasy dirt.Adjust direction that kitchen range top return air arm rotatable connector makes return air hole and oil smoke blowed to the oil smoke suction inlet from the four sides of the kitchen range top, make its with wall is installed is not contacted then and can not form greasy dirt.When steam was tied water in backwind tube, water droplet flowed back to cabinet along tube wall and lower inclined plane.

The present invention has the following advantages compared to existing technology:

1. utilize current, gasflow clean-up, separation oil smoke, flue dust, automatically filtering sump oil, flue dust.

2. do not tie greasy dirt, oil dripping is not oil-proof, and inner automatically the cleaning removed from and being unpicked and washed.

3. cleaned air passes can directly be discharged to outdoorly, does not need to be higher than the flue on roof, eliminates the fume pollution to indoor and outdoor surroundings.

4. utilize return air to increase suction control function, improved the efficient that oil smoke sucks oil smoke.

5. because fan is located in the purification pipe, help reducing noise.

6. this machine can be used for by outdoor to indoor air and the equipment dedusting that purification is provided.

7. this machine can also be used for material showy between collection work, as the molding powder in plastic-blasting workshop.
