ABSTRACT:
A hollow-core nozzle structure which can provide solid core beam typically generated by a solid-core nozzle. The hollow-core nozzle structure contains (1) a hollow passage which is in communication with a water inlet connected sideways to the hollow passage; (2) a water outlet at an end of the hollow passage; (3) a bell-shaped stream-guide plate furnished on an outer rim of the water outlet. The stream-guide plate is provided with, in the order away from the outer rim, a plurality of first, second, and third water baffles respectively arranged in a circular manner. The first water baffles are rectangular in shape, the second water baffles are also rectangular shape but with a bevel on one thereof facing inward, and the third water baffles are triangular in shape, so as to cause a portion of sprayed water to be broken into tiny drops which exit the stream-guide plate along a central line and an outer rim of a water beam to form a solid water beam.
