Abstract

The utility model discloses a dust-collecting cleaning fume exhauster, which uses a simpler host machine box (air filter device). The utility model can solve the two problems of exhaust pollution and difficult cleanness of greasy dirt produced by the machine. The lower part of the host machine box is provided with a liquid cleaning groove; a bending wing plate, a suction guide plate and a water baffle on the upper part of the host machine box form an air fastness suction passage. When an exhaust device is run, large quantities of liquid drops are generated on the liquid cleaning surface to complete the work of dust collection and cleaning. The greasy air is filtered when exhausted through an exhaust opening. The utility model neither pollutes outer air, nor dirty the machine. The utility model solves the two problems which can not be solved by a general fume exhauster simultaneously.
