SPRAY HEAD FOR CLEANING CAPABLE OF EASILY EXCHANGING WORN VALVE SEAL BY SEPARATING DISCHARGE PIPE ONLY FROM NOZZLE PIPE AND CLEANLY CLEANING INNER SURFACE OF SPRAY HEAD BY PREVENTING ECCENTRICITY OF BRUSH SHAFT DURING ROTATION OF BRUSH SHAFT

摘要

PURPOSE: To provide a spray head for cleaning that easily exchanges valve seal worn out according to use of the valve seal for a long period of time, increases cleaning efficiency by cleanly cleaning the inner surface of the spray head, thereby preventing drop of injection pressure of cleaning water and simply assembles or exchanges nozzles fixed to nozzle pipe in one touch type. CONSTITUTION: In a spray head for cleaning constructed such that cleaning water flown in a fixing body(1) through an inlet(8) is sprayed from nozzles(4) by passing through a nozzle pipe(3) connected to a distance maintenance body(2), a brush shaft(6) having a brush(61) is rotatably slid in the nozzle pipe by rotation of a driving shaft(5) formed in the fixing body, and cleaning water is discharged through an outlet(71) according to operation of the driving shaft, the spray head for cleaning is characterized in that the fixing body comprises a guide(13) on which a female screw(12) is formed such that a driving shaft(5) on which a male screw(51) is formed is rotatably moved back and forth by a handle(11), a stopper(52) is formed at one side of the male screw to restrict movements of the driving shaft, and a discharge pipe(7) on which the outlet is formed is fixed to an opened free end portion of the nozzle pipe, and an orifice is airtightly fixed to a front part of the discharge pipe.
