Wherein, the length of bolt 3111 is greater than the removal distance that casing 21 moved to the second station by first station, can guarantee from this that rotation base 311 can follow casing 21 and rotate all the time, also can avoid appearing making the unable normal use condition of sprinkler because of casing 21 breaks away from with rotation base 311.

On the basis of any one of the above embodiments, the spraying part further comprises a water-blocking plectrum 6 rotatably connected with the shell 21 and used for blocking the liquid sprayed out through the nozzle 22, and when the water-blocking plectrum 6 is stirred to the outlet of the nozzle 22, the water-blocking plectrum can disperse the liquid sprayed out through the nozzle 22 into water mist, so that the liquid can be sprayed more uniformly.

On the basis of any one of the above embodiments, the spraying device further includes a blocking member 7 sleeved on the liquid supply tube 1 and located at two sides of the housing 21, for preventing the head member 2 from being separated from the liquid supply tube 1, and the movable position of the housing 21 on the liquid supply tube 1 can be limited by the blocking member 7, so that the situation that the spraying device cannot be normally used due to the separation of the housing 21 from the liquid supply tube 1 can be avoided.

On the basis of any one of the above embodiments, the spraying device further includes a first sealing ring 8 sleeved on the liquid supply tube 1 for preventing the liquid from flowing out from between the liquid supply tube 1 and the lower protrusion 212, so as to prevent the liquid from flowing out from between the lower protrusion 212 and the liquid supply tube 1, and further avoid the waste of resources.

On the basis of any one of the above embodiments, the spraying device further includes a pressing cap 9 connected to the upper protrusion 213, a second sealing ring 10 is disposed between the pressing cap 9 and the upper protrusion 213, the pressing cap 9 can prevent liquid from flowing out from between the upper protrusion 213 and the liquid supply tube 1, so as to avoid waste of resources, and prevent the spraying device from being unable to be used normally due to the case 21 being separated from the liquid supply tube 1.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The spraying device provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
