摘要

The present invention relates to a ring type air knife with a dust collection area extending structure, and particularly, to a ring type air knife with a dust collection area extending structure, capable of extending a dust collection area by injecting a fluid. The air knife (10) with a dust collection area extending structure includes: a blade module (11) comprising a blade hole (113) formed at the center and a ring type body (111) surrounding the blade hole (113); an induction module (14) comprising an inflow path (141) with one end connected to the blade module (11) and a fixing unit (143) formed at one end of the inflow path (141); a housing (13) wherein the induction module (14) is arranged inside; and a nozzle assembly (12) which can spray the fluid into the blade hole (113) while being arranged in the inflow path (141). The ring type air knife with a dust collection area extending structure can collect dust of all areas requiring dust collection by installing an additional injection nozzle while having a ring type structure.
