The interior of the nozzle shell is divided into an inner cavity and an outer cavity by an annular body, and one end of the annular body is fixedly connected to the annular connecting piece through a connecting rod. The atomizing guide body includes a spiral blade located in the outer cavity and a three-leaf spiral airflow vane fixed on the inner wall of the other end of the annular body. The annular connecting piece is also connected to a water inlet flange. The spiral blades and the three-leaf spiral airflow vane convert the exogenous fluid directly input from the water inlet flange into a high-speed rotating fluid required for atomization.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned atomizing nozzle can only atomize water, but cannot be rotated, and the spray range is short, the spray area is small, and it cannot be sprayed according to the required spraying location.

A sealing strip 11 is rotatably connected to the top of the movable ball 10, which is inserted into the interior of the connecting nut 1 through the connecting pipe 2, and inserted upward into the interior of the protective shell 3, and the connecting nut 1 is rotated to be spirally clamped and fixed. A nozzle 12 is fixedly connected to the top of the sealing strip 11, and a plurality of groups of circular holes are opened on the top of the nozzle 12. A rotating block 13 is fixedly connected to the outside of the nozzle 12, and a plurality of groups of holes are opened on the outside of the rotating block 13. Six groups of rotating blocks 13 are provided. By arranging multiple groups of circular holes at the top of the nozzle 12, the effect of water atomization is better, thereby achieving the purpose of saving water.

[0023] Specifically, a support block 14 is fixed to the right side of the connecting nut 1 by welding, a second movable plate 15 is attached to the front side of the support block 14, a slide groove is opened on the front side of the support block 14, and a slide groove is opened inside the second movable plate 15.

[0028] Working principle:

[0029] First, the staff inserts the connecting pipe 2 into the inside of the connecting nut 1, and inserts it upward into the inside of the protective shell 3, and rotates the connecting nut 1 to screw it and fix it. At this time, the water flows through the inside of the connecting pipe 2 and enters the inside of the filter 18. At this time, the water flows through the gasket 21, and the gasket 21 squeezes the spring 20 to slide upward inside the filter 18. At this time, the water flows out from the outside of the gasket 21, and is discharged through the circular groove at the top of the filter 18, and is sprayed from the top of the nozzle 12, and is discharged from the inside of the circular hole groove of the rotating block 13 outside the nozzle 12. The state of the sprayed water flow is related to the flow rate. When the flow rate is small, the sprayed water forms a water column. When the flow rate is large, the fine water column breaks to form droplets, which become water mist. The spray direction can be adjusted by turning the rotating block 9 and the movable ball 10, and the motor 6 inside the protective shell 3 is rotated, and the motor 6 drives the first gear 5 to rotate, and the first gear 5 drives the central gear 7 to rotate, thereby driving the rotating block 9 to rotate, and the sprayed mist water is sprayed, so as to achieve the purpose of saving water.

[0030] When the nozzle 12 is not in use, the water pipe only needs to be placed inside the support block 14, and the support block 14 is moved downward to form an inclined state, and the latch 16 is turned clockwise, at which time the support block 14 and the fixing plate 17 clamp the water pipe for easy use next time.
