a water inlet channel is formed among the water inlet 14, the inner pipe 5 and the outer pipe 6, the inner pipe 5 and the sprayer shell 1 and the rotational flow port 9; and air inlet channels are formed between the right end of the inner pipe 5 and the base 7, between the inner pipe 5 and the linkage shaft 4 and at the left end of the linkage shaft 4 in a way of penetrating through the cyclone ring 3.

A flow guide ring 11 is arranged between the upper flow ring 3 of the inner pipe 5 and the outer pipe 6; a plurality of diversion ports 13 are arranged around the periphery of the diversion ring 11.
