Claims

[Claims for Utility Model Registration] (1) A ball that is inserted into the head of a nozzle base so as to create a space around it and has a nozzle opening along the jetting direction of the nozzle base, and the nozzle base a switching knob that is provided outside the head and rotates the ball so that the nozzle can change direction on the nozzle direction line; A cap having a center hole that coincides with the center hole and an outer hole provided around the center hole; a core having an outer circumferential groove communicating with the hole; and a first core provided on the nozzle base so as to be in sliding contact with the outer circumferential surface of the ball and abutting around the inlet side of the nozzle when the nozzle is on a straight injection line. a seal body, and a second seal body provided on the inlet side of the mouthpiece so as to be in sliding contact with the outer circumferential surface of the ball and abutting around the outlet side of the nozzle when the nozzle is on a straight injection line; When the ball is set in the straight forward position using the switching knob, the jetting hole matches the center opening of the core through the center hole of the base and the liquid is injected straight, and the ball is set in the spreading position using the switching knob. Then, the ejection hole matches the outer circumferential groove of the core through the outer hole of the cap, and the liquid is diffused and sprayed.Further, when the ball is set to the stop position by the switching knob, the ejection hole passes through the center hole of the cap and A nozzle device characterized in that the nozzle does not match any of the outer holes and no liquid is sprayed. (2) The nozzle device according to claim 1, wherein the outer peripheral groove of the core is a spiral groove. (3) In the case where the core is indirectly attached to the mouthpiece by a double tube, the core is held in a nozzle tube, the outer tube of the double tube is connected to the nozzle tube, and the double tube is connected to the nozzle tube. The nozzle device according to claim 1 or 2, wherein the inner tube is communicated with the center opening of the core.
