The nozzle 2 rotates: through the driving gear 8 and the inner pipe gear 6, the motor 7 drives the long inner pipe 3 to rotate, the long inner pipe 3 drives the plurality of nozzles 1 on the spray head 2 to rotate, and the motor 7 drives the plurality of nozzles 1 to rotate; if the motor 7 has a remote control, a person can remotely control the forward or reverse rotation of the plurality of nozzles 1, as well as the rotational speed. The water pressure cannot control the forward rotation or reverse rotation of the nozzle 1, and the rotation speed.

Water spraying: the water in the external water pipe 13 enters the water storage space 10 between the short outer pipe 4 and the long inner pipe 3 from the water inlet hole 12 of the external water pipe 13, and then enters the pipe of the long inner pipe 3 from the plurality of water guide holes 11 on the wall of the long inner pipe 3 in the short outer pipe 4, and finally enters the spray head 2 and is sprayed out from the plurality of nozzles 1.

The utility model has the advantages that: the water sprayed from the nozzle is determined by the water pressure, and the rotating speed and direction of the spray head are determined by the motor, so that the spraying height and rotating mode can be arbitrarily combined to produce artistic line type with various spraying height and rotating mode combinations.
