Description

Technical Field

[0001] The utility model belongs to the technical field of irrigation, and particularly relates to a municipal garden irrigation device. Background Art

[0002] In gardens, the importance of irrigation equipment is self-evident. It is a technical measure for supplementing the water required by crops. Good irrigation equipment can ensure the growth of green plants. In order to save water, most of the irrigation equipment in gardens is of the sprinkler type.

[0003] Chinese Patent with the publication number of CN220383843U discloses a municipal garden irrigation device, including a connecting pipe and a spray pipe. The connecting pipe and the spray pipe are in threaded connection. A partition plate is fixedly installed on the inner wall of the spray pipe. The top end of the spray pipe is of an open structure. A plurality of rectangular openings are evenly formed in the circumferential direction at the top end of the spray pipe. A water outlet pipe is rotatably installed on the inner wall of the rectangular opening through a rotating shaft. An irrigation nozzle is fixedly installed at one end of the water outlet pipe facing the outside of the spray pipe. A plurality of through holes are evenly formed through the upper surface of the partition plate. A flexible pipe is fixedly installed at one end of the water outlet pipe away from the nozzle, and the other end of the flexible pipe is communicated with the inside of the through hole.

[0004] However, the above-mentioned existing municipal garden irrigation device still has certain deficiencies in actual use.
