Claims (1)

[Scope of Claim for Utility Model Registration] (1) A double liquid feeding tube consisting of an outer tube and an inner tube, a communication inner hole attached to the tip of the double liquid feeding tube and communicating with the inner tube, and this communication. a rotating core member having a communicating outer hole located near the outer periphery of the inner hole and communicating with the outer tube; an opening rotatably fitted onto the outer circumferential surface of the rotating core member and communicating with the communicating inner hole; a rotary member having an inner hole for opening and an outer hole for opening that is located near the outer periphery of the inner hole for opening and communicates with the outer connecting hole; A core having a center hole that communicates with the center hole, a swirl chamber formed in front of the center hole, and a swirl hole that opens in a radial direction around the swirl chamber and communicates with the opening outer hole, this core. a spout plate disposed in front of the rotary member and having a spout port, and a cap attached to the outer peripheral surface of the distal end of the rotary member to attach the core and the spout plate to the rotary member, the liquid being supplied to the inner tube. The liquid enters the center hole of the core through the communication inner hole and the opening inner hole, and is injected straight from the spout, and when the liquid is supplied to the outer tube, and a nozzle device, characterized in that the liquid enters the swirl hole of the core through the opening outer hole, is given a swirling force by the swirl hole, and is sprayed from the nozzle in a circular diffusion manner. (2) A nozzle device according to claim (1), comprising a fan-shaped diffusion jet adapter that is detachably attached to the cap and that changes the liquid circularly diffused and jetted from the nozzle into a fan shape.
