The present invention relates to a sprinkler; in particular to an innovative structural designer having a fixed angular displacement when actuating.

According to the conventional horticulture sprinklers used to irrigate flowers and trees (referred to as percussive sprinklers that can produce automatic rotation when sprayed by water), the main structure of the sprinklers is large body by body, into The water pipe, the top frame, the guiding member, the outlet pipe and the like are formed, and the outlet pipe is disposed at a slightly oblique angle on the side of the sprinkler body, so that the water flow is introduced by the inlet pipe When the water pipe is sprayed out, the water flow will be configured as a parabolic water flow due to the inclined arrangement of the water outlet pipe, and the rotating member can be continuously reciprocated to swing back and forth, and the automatic rotating spray can be generated to achieve the automatic surface. The purpose of irrigation.

However, when the conventional structure shows that the conventional sprinkler is used for irrigation spraying, the water supply is unsteady, so that when the water flow is sprayed from the outlet pipe, the thrust of different forces is relatively generated. Therefore, the impact force of the sprinkler is not uniform every time. Relatively, with the uneven impact force, the rotation angle of the sprinkler is also different every time, which ultimately results in uneven humidity after sprinkling irrigation. , which causes problems such as cultivation, conservation, and growth of crops.
