Abstract: An airstream guidance can gather up exhaust by the gaseous guidance to change the flowing direction of air stream in a more effective way. It can exert the jet airstream immediately gathering the air and soot to exhaust outdoors via the suspension fan or via other air-extracting fittings as to improve the defects such as an escape of exhaust or the scattered soot. Besides, the present invention can be assembled or disassembled easily so as to clean. As to the production, it can lower the costs and increase the market competition.

Abstract: The present invention relating to an airstream guidance is the device of another form of a jet airstream guidance, in which can gather up exhaust by the gaseous guidance to change the flowing direction of air stream with effect and can exert the jet airstream immediately gathering the air and soot to exhaust outdoors via the suspension fan or via other air-extracting fittings as to improve the defeats such as an escape of exhaust or the scattered soot; besides the present invention can assemble or disassemble simply so as to clean, and as to the production, it can lower the costs and rise the market competition.
