The working principle of the automatic swinging nozzle 100 of the present embodiment is as follows:

vertical swinging: after the high-pressure rivers of blowout in nozzle 10, high-pressure rivers hit and beat in the water conservancy diversion hole of one side at two-way guide plate 16, two-way guide plate 16 and layer board have received the decurrent effort of high-pressure rivers, drive perpendicular swing arm 15 and rotate downwards, after perpendicular swing arm 15 rotates down to the limit, upwards rotate again under the effort of torsional spring, after perpendicular swing arm 15 upwards rotated the height of high-pressure rivers, high-pressure rivers will strike two-way guide plate 16 and tray, then perpendicular swing arm 15 rotates downwards again, so perpendicular swing arm 15 reciprocates and constantly carries out the rocking of direction from top to bottom.

Left-right swinging: after the high-pressure water flow is sprayed out of the nozzle 10, the high-pressure water flow hits the guide hole on one side of the two-way guide plate 16, and at the same time, the high-pressure water flow of the two-way guide plate 16 is also acted by the leftward or rightward force, so that the two-way guide plate 16 drives the supporting plate, the vertical swing arm 15, the mounting rod 17 and the reversing driven arm 14 to move to the extreme position leftward or rightward, and then drives the guide pipe 6, the elbow 5, the rotating upper seat 4 and the rotating lower seat 3 to rotate together, after the reversing stop lever 11 is limited by one limiting rod 201 of the reversing spring 2, the reversing stop lever can rotate, the reversing stop lever 11 can drive the reversing driving arm 12 to rotate, the reversing rotating arm can drive the reversing connecting rod 13 to rotate, and because the reversing connecting rod 13 is provided with the spring 23, the spring 23 always pushes the sliding block 22, and when the reversing driving arm 12 rotates to the other side, the spring 23 acts on the force, the reversing connecting rod 13 can also change the direction to rotate along with the reversing connecting rod, the reversing driven arm 14, the mounting rod 17 and the vertical swing arm 15 can be driven to rotate by the rotation of the reversing connecting rod 13, and the vertical swing arm 15 can be driven to rotate after rotating, so that high-pressure water flow can strike on the guide plate on the other side of the bidirectional guide plate 16, the vertical swing arm 15 is changed to rotate to the limit position in the other direction, and then the guide pipe 6, the elbow 5, the rotating upper seat 4 and the rotating lower seat 3 are driven to rotate together in the other direction, so that the left and right directions are repeatedly swung.

In the automatic swinging nozzle 100 of the embodiment, the reversing driven arm 14 is positioned above the reversing driving arm 12, the reversing connecting rod 13 is positioned between the reversing driving arm 12 and the reversing driven arm 14, the reversing driven arm 14 is positioned below the flow guide pipe 6, the overall structure of the reversing mechanism is compact, and high-pressure water columns sprayed out of the flow guide pipe 6 are not easy to splash onto the reversing connecting rod 13 and are not easy to splash into the reversing connecting rod 13, so that the problem that a spring 23 in the reversing connecting rod 13 rusts due to water is avoided; through set up the friction ring 28 of polytetrafluoroethylene material in rotating lower seat 3, friction ring 28 is wear-resisting, has improved the life of automatic shower nozzle 100 that sways.
