The movable bearing rod 9 is in contact with the inner wall of the linkage channel 81. A connecting matching strip 82 is symmetrically fixedly provided on the inner end surface of the sealing plate 8, and a connecting matching groove 83 is provided on the connecting matching strip 82. A connecting carrier block 45 is inserted in the connecting matching groove 83, and the connecting carrier block 45 is in contact with the inner wall of the connecting matching groove 83.

[0064] A method for irrigating vegetation on a building exterior wall comprises the following steps:

[0065] Step 1: Moving the nozzle 6 outward: Activate the hydraulic rod 18 to drive the driving strip 5 to move downward, thereby driving the nozzle 6 to move out of the outward moving channel 16;

[0066] Step 2: Locking between the nozzle 6 and the movable sleeve 4: As the nozzle 6 moves, the interlocking bearing rod 71 is inserted into the interlocking channel 64 to achieve locking between the nozzle 6 and the movable sleeve 4;

[0067] Step 3: Release of rainwater: As the blocking plate 8 rotates, the movable bearing rod 9 is driven to move, so that the matching blocking plate 94 is no longer blocked at the watering hole 14.

[0068] The irrigation pipe 3 is connected to the water-saving sprinkler irrigation machinery under the existing technology. When it rains, part of the rainwater will be collected in the water pool 13. When it is necessary to irrigate the vegetation on the outer wall 2, the hydraulic rod 18 is started to drive the driving strip 5 to move downward. As the driving strip 5 moves downward, the movable sleeve 4 will be pushed to move in the direction of the outward movement channel 16 under the action of the matching connecting rod 48. As the movable sleeve 4 moves, the connecting block 45 and the connecting matching groove 83 will push the sealing plate 8 to rotate, so that it is no longer blocked in the outward movement channel 16, so that the nozzle 6 can move outward smoothly, which is convenient for the nozzle 6 to spray water for irrigation. When no irrigation work is done, the sealing plate 8 covers the outward movement channel 16, which can The closure plate 8 is hidden to ensure the overall aesthetics, and when the closure plate 8 is rotated, the linkage channel 81 and the mobile bearing rod 9 will drive the mobile bearing rod 9 to move away from the bearing irrigation box 1. As the mobile bearing rod 9 moves, it will also drive the matching blocking plate 94 to move, so that the matching blocking plate 94 no longer blocks the watering hole 14. In this way, if rainwater accumulates in the water pool 13, the rainwater can flow down from the watering hole 14 to irrigate the vegetation. When the rainwater cannot meet the demand for irrigation of vegetation on the outer wall 2, it can be irrigated through the sprinkler 6, which can make good use of the rainwater and is beneficial to the conservation of water resources. In addition, the movable sleeve 4 drives the sprinkler 6 to the bearing irrigation box 1. During the external movement, the contact carrier block 7 on the movable sleeve 4 will contact the limiting matching block 161, so that the contact carrier block 7 will no longer move under the restriction of the limiting matching block 161, because the contact carrier block 7 does not move, and the movable sleeve 4 is moving at this time, so the distance between the contact carrier block 7 and the movable counterweight ring 74 will gradually decrease. As the distance between the movable counterweight ring 74 and the contact carrier block 7 decreases, the movable counterweight ring 74 will be pushed upward along the bearing strip 44 under the action of the connecting movable rod 73, and at the same time, the interlocking bearing rod 71 will also be inserted into the interlocking channel 64. When the interlocking bearing rod 71 is inserted into the interlocking channel 64, the locking between the movable sleeve 4 and the nozzle 6 is realized, which can ensure the The invention relates to a novel method for the injection molding of a nozzle 6, which is used to manufacture a nozzle 6 with a plurality of nozzles. The nozzle 6 is fixed to the nozzle 6, and the sealing plate 67 is tightly covered on the connecting convex tube 47 during the injection molding process. The sealing of the connection between the nozzle 6 and the movable sleeve 4 is ensured. When the nozzle 6 is in the carrying irrigation box 1, the interlocking bearing rod 71 is not inserted into the interlocking channel 64, so that the movable sleeve 4 and the nozzle 6 are not in a locked state. When the nozzle 6 is blocked, it is convenient for the staff to quickly remove it for maintenance or replacement. The operation is simple, convenient and fast. Moreover, when the nozzle 6 is not removed from the carrying irrigation box 1, the sealing plate 94 is used to block the lower port of the watering hole 14, so that the watering hole 14 can be blocked.It is convenient for rainwater to be stored in the water pool 13.

[0069] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
