The cleaning of impeller and motor output end face needs to remove earlier impeller, and from top dismounting motor, blade rigid is low again, and this gives again and tears, washes, adorns the increase difficulty open.The spiral case inner surface since long-pending oil can not arrange, of long duration it, the very thick one deck that will condense, more difficult removing.Comprehensively above-mentioned, present polytype smoke exhaust owing to structural reason, can't solve above two difficult problems that people pay close attention to most.

The purpose of this utility model is to solve problems of the prior art, provides a kind of suction, row effective, pollutes for a short time, and it is convenient to clean, i.e. the suitable again oil soot exhaustor of economy.

Technical solution of the present utility model is: by exhaust fume collecting hood (1), exhaust blower (2), motor (10), spiral case (3), exhaust duct (4) is formed, of the present utility model be characterised in that above-mentioned exhaust fume collecting hood (1) be umbrella shape make its flue gas flow direction and cover mouthful suck an air flow direction to conform to, be furnished with exhaust blower (2) and the motor (10) that is assemblied in the spiral case (3) on the top of above-mentioned exhaust fume collecting hood (1), at the exhaust outlet place of spiral case (3) exhaust duct (4) is housed, the exhaust outlet downside (7) of above-mentioned spiral case (3) is made skewed, dispose one at the air inlet of spiral case (3) and can prevent oil, water flows to the oil baffle (5) of exhaust hood inner surface, be equipped with the V-type dividing plate (8) that can roll on the top of spiral case (3), motor (10) exhaust blower (2) is assemblied in the V-type dividing plate (8).

The utility model is when adopting the said structure scheme, successfully used air fluid mechanics optimal design principle, straight suction, in line purpose have been realized, compared with similar products, has the exhaust efficiency height, pollution discharge capability is strong, long-pending oil and exhaust are in same runner, and by the clumsy air velocity of row, having finished the long-pending oil of the interior nothing of spiral case more up hill and dale condenses, this peculiar exhaust is discharged incorporate totally-enclosed air channel design with long-pending oil, has realized no draining hole and oil collection box in the machine, provides convenience to scouring.

Below be that Figure of description is briefly explained.
