<p>PROBLEM TO BE SOLVED: To provide a nozzle structure which can efficiently spray (apply) a liquid against (to) a matter to be sucked, and more particularly, to provide a nozzle structure which can strongly spray (apply) the liquid over an extensive range. SOLUTION: In the nozzle structure which is connected to a suction device and use to such the matter to be sucked, a buffer plate is provided substantially parallel to an opening surface on the internally distal side of the opening surface facing the matter to be sucked in the nozzle, the surface area of the buffer plate is smaller than the sectional area of a hollow portion of the nozzle at the position where the buffer plate is provided, and liquid spray holes to spray the liquid to be sprayed against the matter to be sucked are formed in the buffer plate.</p> |
