Detailed Description

The present invention will be further described with reference to the following examples.

Example 1: according to the figures 1-3, a vertical rocker arm type automatic spray head is known, when water flow enters the spray head 13 through the flow stabilizing pipe 4, the water flow impacts the spiral impeller 16 to rotate anticlockwise, the rotation of the spiral impeller 16 can also primarily disperse the water flow, the water flow is prevented from being sprayed in a pile, water resources are effectively saved, because one end of the transverse plate 20 is positioned on the rotating track of the spiral impeller 16, when the spiral impeller 16 rotates anticlockwise, the spiral impeller contacts with the lower wall of the transverse plate 20, the transverse plate 20 is driven to synchronously lift upwards, the inner diameter of the spray head 13 is reduced, according to the fluid acceleration principle, the water flow is pressurized and accelerated at the moment and finally enters the top cover 14 to be sprayed out through the water spraying hole 15, at the moment, the motor 24 drives the rotating shaft 25 to rotate, the dispersion shaft 26 is driven to rotate through the motor 27, the rotary cap 28 drives the dispersion plate 29 to rotate, so that a plurality of sprayed columnar water flows are dispersed into a waterfall type spray, the sprinkling irrigation area is effectively increased, particularly, the blades in the spiral impeller 16, which are in contact with the transverse plate 20, can be separated from the transverse plate 20 after rising to a specific height gradually in the upward rising process, at the moment, the transverse plate can reset under the action of the spring 19, at the moment, the next blade of the spiral impeller 16 is in place and is in contact with the transverse plate 20, the adjusting plate 18 is pulled up again and repeated, and therefore the whole process of accelerating water flow is achieved, in order to prevent the impeller from reversely rotating, the sprinkling irrigation device is further provided with a limiting assembly, the impeller can only rotate anticlockwise, and the sprinkling irrigation device is convenient to use.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
