[0032] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0034] Combination Figure 1-Figure 12 As shown, the utility model provides an insect-proof spray head, comprising a U-shaped connecting frame 1, a mounting sleeve 2, a limiting column 3, a water collecting head 4 and a rotating spraying member 5.

[0035] In this embodiment, the mounting sleeve 2 and the limiting column 3 are respectively fixedly connected to the two ends of the U-shaped connecting frame 1, the limiting column 3 is coaxially arranged with the mounting sleeve 2, and the mounting sleeve 3 is located directly below the limiting column 3. A limiting groove 31 is provided at the lower end of the limiting column 3, the water collecting head 4 passes through the mounting sleeve 2 and is fixedly connected to the mounting sleeve 2, the rotating spraying member 5 is located between the water collecting head 4 and the limiting column 3, and includes a spraying plate 51, a guide structure 52 connected to the middle part of the lower side of the spraying plate 51, a rotating structure 53 located outside the guide structure 52, and a guide rod 54 connected to the middle part of the upper side of the spraying plate 51, the guide structure 52 extends into the water collecting head 4 and is movably connected to the water collecting head 4, the guide rod 54 extends into the limiting groove 31 and is movably connected to the limiting groove 31, there is a gap between the top of the guide rod 54 and the bottom of the limiting groove 31, and the distance between the guide rod 54 and the bottom of the limiting groove 31 is less than the height of the guide structure 52, so as to prevent the rotating spraying member 5 from being separated.

[0036] The insect-proof spray head of the utility model can be connected to a water supply pipe at the lower end of the water collecting head 4 through the above arrangement, and water is supplied upward through the water collecting head 4. The high-pressure water impacts the flow guiding structure 52 and the spraying plate 51, which can drive the spraying plate 51 to move upward. At the same time, due to the arrangement of the flow guiding structure 52 and the rotating structure 53, the water flow can drive the spraying plate 51 to rotate, so as to realize the rotating spraying of the irrigation water, with high spraying uniformity and a large spraying range. When the irrigation is completed, the spraying plate 51 falls back on the water collecting head 4, so as to prevent insects, dust and sand from entering the water collecting head 4 and causing the water collecting head to be blocked.

[0037] Combination Figure 1 , Figure 4 , Figure 9-12 As shown, according to one embodiment of the utility model, the guide structure 52 includes a first arc-shaped cylinder 521 and a second arc-shaped cylinder 522 which are symmetrically arranged, and an inclined guide plate 523 is connected between the first arc-shaped cylinder 521 and the second arc-shaped cylinder 522, and a first inclined guide boss 524 and a second inclined guide boss 525 are respectively provided on both sides of the inclined guide plate 523, and the first inclined guide boss 524 and the second inclined guide boss 525 are symmetrical about the center point of the spray plate 51, and the first inclined guide boss 524 and the second inclined guide boss 525 are respectively fixedly connected to the spray plate 51, the first arc-shaped cylinder 521, the second arc-shaped cylinder 522 and the inclined guide plate 523.

[0038] In this embodiment, the rotating structure 53 includes two sets of rotating components that are centrally symmetrical about the center point of the spray plate 51 . The rotating components include a guide inclined plate 531 and a rotating boss 532 . The rotating boss 532 has a rotating inclined surface 5321 .

[0039] According to one embodiment of the utility model, the water collecting head 4 includes a bottom cylinder section 41, an intermediate cylinder section 42 and a top cylinder section 43 connected in sequence, the intermediate cylinder section 42 is fixedly matched with the mounting sleeve 2, and a partition 44 is provided between the intermediate cylinder section 42 and the top cylinder section 43, and a through hole 45 is provided on the partition 44 to connect the top cylinder section 43, the intermediate cylinder section 44 and the bottom cylinder section 41.

[0040] According to an implementation mode of the utility model, the U-shaped connecting frame 1, the mounting sleeve 2 and the limiting column 3 of the utility model are an integrally formed structure, the water collecting head 4 is an integrally formed structure, and the rotating spraying member 5 is an integrally formed structure.

[0041] The assembly process of the insect-proof sprinkler of the utility model is as follows:

[0042] First, extend the guide rod 54 of the rotating spraying member 5 into the limiting groove 31 for engagement, and then pass the water collecting head 4 through the mounting sleeve 2 so that the flow guiding structure 52 is engaged with the top cylinder section 43 , and at the same time, the middle cylinder section 42 is tightly engaged and fixed with the mounting sleeve 2 .

[0043] The working principle of the insect-proof sprinkler of the utility model is as follows:

[0044] The irrigation water supply is transported to the water collecting head 4 through the pipeline. After passing through the through hole 45, the irrigation water 4 is further pressurized and transported upward. The water flow impacts the guide structure 52 and the spray plate 51 to lift the spray plate 51, so that the first inclined guide boss 524 and the second inclined guide boss 525 are higher than the upper surface of the top cylinder 43, and then the water flow on the first inclined guide boss 524 and the second inclined guide boss 525 is mostly impacted on the rotating inclined surface 5321 of the rotating boss 532, so that under the action of the rotating boss 532 and the guiding inclined plate 531, the spray plate 51 is rotated, so that the irrigation water is sprayed in a circular direction along the spray plate 51. After the spraying is completed, the spray plate 51 falls back to the upper surface of the top cylinder section 43 to achieve a protective effect.

[0045] The insect-proof sprinkler of the utility model, through the arrangement of the guide structure 52 and the rotating structure 53, obtains that most of the water flow impacts on the rotating inclined surface 5321 of the rotating boss 532, so that the rotation driving force is greater, thereby achieving a wider range of spraying. At the same time, due to the arrangement of the guide structure 52, the guide inclined plate 531 and the rotating boss 532, it can also play a guiding role, making the irrigation water spray more uniform.

[0046] According to an embodiment of the present invention, the end of the guide rod 54 extending into the limiting groove 31 is configured as a hemispherical structure. This configuration can improve the rotation stability of the rotating spraying member 5, thereby further improving the spraying stability and uniformity.

[0047] The above is only one embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
