Low Pressure Fogging Device

摘要

A low pressure fogging device includes a fogging device body having a hose coupling tube formed unitarily with the lower side thereof, a screw portion formed on the upper side thereof, and a fluid flow-inducing member seating plate formed on top of the screw portion; a fluid flow-inducing member having induction wings seated on top of the fluid flow-inducing member seating plate; a nozzle body having a fitting hole open downwardly therefrom to allow the fluid flow-inducing member seating plate and the fluid flow-inducing member to be fitted thereto; and a push-up nut having a pressuring ring formed at the center thereof to be locked onto a locking projection formed from an outer lower end periphery of the nozzle body and a screw groove formed at the inner periphery thereof to be fastened to a screw portion formed on the fogging device body.

主权项

1. A low pressure fogging device (1) comprising:
a fogging device body (2) having a hose coupling tube (22) formed unitarily with the lower side thereof around a boundary flat plate (21), a screw portion (24) formed on the upper side thereof around the boundary flat plate (21), a fluid flow-inducing member seating plate (26) formed on top of the screw portion (24) and having a ring groove (25) formed thereon in such a manner as to be coupled to an O-ring (7), and a water supply hole (27) penetratedly formed from the hose coupling tube (22) to the center of the fluid flow-inducing member seating plate (26); a fluid flow-inducing member (3) having induction wings (31) seated on top of the fluid flow-inducing member seating plate (26), an induction tube (32) formed on the underside of the induction wings (31) in such a manner as to be fitted to the water supply hole (27), a contacting protrusion (33) formed upwardly from the induction wings (31) in such a manner as to be inserted into a nozzle body (4) and come into contact with vortex passages (42) formed on the nozzle body (4), and passages (34) adapted to induce and supply a fluid; the nozzle body (4) having a fitting hole (41) open downwardly therefrom in such a manner as to allow the fluid flow-inducing member seating plate (26) of the fogging device body (2) and the induction wings (31) of the fluid flow-inducing member (3) to be fitted thereto, arch-shaped facing coupling protrusions (41a) formed on top of the fitting hole (41) and having a smaller diameter than the fitting hole (41), the vortex passages (42) formed on the ceiling of the fitting hole (41), and a nozzle hole (43) formed on the center of the ceiling of the fitting hole (41) in such a manner as to be connected to the vortex passages (42); and a push-up nut (5) having a pressuring ring (51) formed at the center thereof in such a manner as to be locked onto a locking projection (44) formed from an outer lower end periphery of the nozzle body (4) and a screw groove (52) formed at the inner periphery thereof in such a manner as to be fastened to the screw portion (24) formed on the fogging device body (2).
