A NOZZLE ASSEMBLY WITH AN AIR CURTAIN FORMING UNIT

摘要

The present invention relates to a nozzle assembly with a combined structure of an air curtain forming unit, and particularly, to a nozzle assembly capable of facilitating low-scattering spraying by forming an air curtain in the spraying direction of a fluid. The nozzle assembly with a combined structure of an air curtain forming unit includes: a nozzle body (111) wherein a nozzle block (113) sprayed with a first fluid is formed; a first fluid supply unit (12) supplying the first fluid to the nozzle block (113) while being combined with the nozzle body (111); a fluid induction unit (15) combined with the front of the nozzle body (111); a second fluid supply unit (13) supplying a second fluid along the circumference of the fluid induction unit (15); an air curtain forming unit (17) combined with the second fluid supply unit (13); an induction housing (16) wherein the fluid induction unit (15) and the air curtain forming unit (17) are accommodated; and a path forming unit (18) which has a uniformly formed path (182) extended in a uniform diameter while being formed in the spraying direction by being combined with the inside of the induction housing (16). Extension length of the air curtain forming unit (17) is equal to or larger than the uniformly formed path (182). The objective of the present invention is to provide the nozzle assembly with an air curtain forming structure which can obtain a uniform diameter of sprayed microparticles by improving arrival efficiency as to a target point since the air curtain is formed in the spraying direction of the fluid.
