Through the screw operation of the adjusting sleeve 26, the relative relationship between the diverging spout 263, the outlet 264 and the adjusting head 254 is adjusted to further adjust the water outlet mode of the second sprinkler head 25, and The outlet top base 20 is matched with a scroll spring 27 to mount the guide member 30, and is bolted and combined by the shaft bolt 28, so that the guide member 30 can swing with the shaft bolt 28 as the axis, and then impact The water outlet top seat 20 generates rotation power to achieve the purpose of rotating the water outlet top seat 20 to sprinkle water.

For the actual use of the structure, please refer to Figures 1 and 4. The sprinkler is installed on a bracket 40 with the water inlet seat 10, and is connected to the water source through the shaft tube 12 to divert to the outlet top seat. The first and second water outlets 21 and 22 of 20, and then spray from the first and second sprinklers 24, 25 to achieve the purpose of sprinkling water. The adjusting head end 254 passes through the outlet 264 and is relatively located in the diverging nozzle 263. At this time, when the water flow enters the collecting chamber 262 from the water outlet 265 and sprays toward the front end of the adjusting sleeve 26, due to the adjustment The end of the head end 254 exceeds the outlet 264 to form a fully open state, allowing a larger amount of water flow to pass through, and sprays along the diverging nozzle 263 to form a spray state with a large range but relatively close distance. The spray state The range and density can be realized by fine-tuning the adjusting sleeve 26.

Secondly, when the adjusting sleeve 26 is screwed to the outside, please continue to observe from the figures 7 and 8. After the adjusting sleeve 26 is screwed to the outside, the guide port 264 is opposite to the end of the adjusting head 254. Schematic diagram of the outer periphery of the part. At this time, because the outlet 264 is blocked by the adjusting head end 254, the space through which the water can pass is reduced, so that the water flow can only be squeezed out from the gap between the outlet 264 and the adjusting head end 254 At the same time, the spraying intensity of the water stream is enhanced to form a water column state with a smaller spraying range but a longer distance, so that the adjustment of the spraying mode can be easily realized through the screw of the adjusting sleeve 26.

Furthermore, please observe the first swing arm 31 of the guide member 30 as shown in Figures 9, 10, and 11 facing the first sprinkler head 24. The pushing portion 311 is provided. When the water flows from the first When the first spray head 24 of the water outlet 21 is sprayed, it will directly impact the pushing portion 311 to make it deflect away from the first spray head 24, and then the first swing arm is driven by the elastic pull of the scroll spring 27 31 swings back to reset, and then generates a bit of energy and hits the spout top base 20 to convert into kinetic energy, and then drives the spout top base 20 to swing and rotate on the top of the base tube 11 with the shaft tube 12 as the axis, so as to be able to use the support 40 as the center of the circular range of sprinkler operations.

With the structure of the above specific embodiment, the following benefits can be obtained: the second sprinkler head 25 of the spout top base 20 discharges water from the side, and is used with an adjusting sleeve 26 in a screw lock manner, so that the second sprinkler The head 25 can achieve the purpose of adjusting the spray mode through the screw operation of the adjusting sleeve 26, which helps to improve the convenience of sprinkling operation, so as to reduce the need to purchase multiple sprinkler heads according to the size of the aperture. Reduce the cost of replacing the sprinkler head.

Furthermore, the outlet top base 20 and the inlet base 10 are combined in a combined manner to facilitate the replacement and maintenance of the outlet top base 20, and the structural type of the outlet top base 20 can be changed according to the different needs of sprinkling operations to achieve Those who achieve the purpose of multiple sprinkler modes and reduce the purchase cost of the sprinkler at the same time.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while at the same time it can achieve industrial utilization and progress. Moreover, this creation has not been seen in any publications, and it is also novel. In accordance with the relevant provisions of the Patent Law, Yan filed a new patent application in accordance with the law, and I implore the Jun Bureau review committee to grant legal patent rights. I really pray.

Only the above is only one of the preferred embodiments of this creation, and should not be used to limit the scope of implementation of this creation; that is, all the equivalent changes and modifications made in accordance with the scope of the patent application for this new model, All should still fall within the scope of this new patent.
