Rotating power element 24 drives drive wheel 22 to rotate, which in turn drives synchronous wheel 23 to rotate, thereby causing elbow 13 to rotate around guide rail 14, achieving rotation at any angle. This allows adjustment of the orientation of through hole 130 of elbow 13, enabling gas and liquid to be sprayed to different positions, making it convenient to use.

[0031] The rotary nozzle device 100 of this utility model drives the elbow 13 to rotate around the fixed base 12 through the cooperation of the drive wheel 22 and the synchronous wheel 23, thereby changing the orientation of the through hole 130 of the elbow 13 and realizing 360-degree spraying; the liquid inlet pipe 32 is connected to one end of the mounting base 31 and the nozzle 33 is connected to the other end to realize liquid spraying; the rotary nozzle device 100 has a simple structure and is easy to use.
