SPRAY DIRECTION CHANGE TYPE SPRAY NOZZLE APPARATUS

摘要

PURPOSE: A spray direction change type spray nozzle apparatus is provided in which spraying region is widened by changing spray direction so that one spray nozzle plays a role of various spray nozzles. CONSTITUTION: The spray direction change type spray nozzle apparatus comprises a base(110) equipped with a guiding groove(112) having a circular arc shaped path; a body(130) mounted on the upper part of the base(110) so that the body(130) is rotated along the guiding groove(112) centering around the central point for the radius of curvature of the guiding groove(112); a spray nozzle(120) mounted on the body(130) with the spray nozzle(120) being connected to a fluid supplying pipe by means of a flexible fitting(122); a rotation shaft(149) mounted on the body(130) so that the rotation shaft(149) is rotationally driven in an axis direction by a driving motor(150); and a link bar(146) one end of which is rotationally connected to a connection pin(148a), and the other end of which is rotationally mounted on the base(110), wherein the connection pin(148a) is moved along with the rotation shaft(149) so that the connection pin(148a) is rotationally reciprocated along a course of a certain radius centering around the rotation shaft(149).
