[0027] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 2 :
[0028] A split rotary sprinkler comprises a joint seat 1 having a water inlet through hole 10, a sprinkler seat 2 being screwed on the top of the joint seat 1, a sprinkler core cavity 20 connected to the water inlet through hole 10 being formed in the sprinkler seat 2, a spray hole 21 communicating with the sprinkler core cavity 20 being provided at the top of the sprinkler seat 2, a rotating core 3 being rotatably arranged in the sprinkler core cavity 20, the rotating core 3 comprising a rotating core seat 30, a sprinkler head 31 abutting against the lower end of the spray hole 21 being inserted at the top of the rotating core seat 30, a counterweight body 32 being inserted at the bottom of the rotating core seat 30, a turnover sleeve 33 being sleeved on the lower end of the counterweight body 32, the outer walls of the turnover sleeve 33 and the sprinkler seat 30 abutting and rotating along the inner wall of the sprinkler core cavity 20, the counterweight body 32, the rotating core seat 30 and the sprinkler head 31 are all provided with interconnected water spray holes 34.
[0029] In the implementation process, the connector seat 1 is a 1 / 4 quick connector for connecting a high-pressure water pipe, which enters the core chamber through the connector seat 1. Since the spray hole position at the top of the core chamber 20 is offset by the nozzle 31, the high-pressure water in the core chamber 20 enters the rotating core and finally sprays out of the spray hole 21 from the spray hole 34 in the nozzle. The rotating core itself is in a rotatable state in the core chamber, so the high-pressure water sprayed is in a rotating state.
[0030] During the process of replacing the rotating core, the threads of the joint seat and the nozzle seat are opened for replacement. The rotating core is composed of a rotating core seat, a counterweight body, a nozzle and a rotating sleeve that are plugged or socketed together. The vulnerable parts can be repaired and replaced by disassembling, which greatly reduces the cost of use.
[0031] Preferably, the material of the rotating core seat 30 and the rotating sleeve 33 is plastic, and the material of the counterweight body 32 is metal.
[0032] In the above structure, since the core holder and the rotating sleeve are the positions that are most often in contact with the inner wall of the core chamber, they are made of relatively low-cost plastic material, which greatly reduces costs during the disassembly and replacement process.
[0033] Preferably, the top of the joint seat 1 is in contact with a connection base 4 that seals the water inlet through hole 10 , and a side wall of the connection base 4 is provided with a plurality of side outlets 40 that are in communication with the spray core cavity 20 .
[0034] During implementation, the function of the connecting base 4 is to form the water sprayed from the water inlet through hole 10 into a rotating water flow, thereby facilitating the rotation of the rotating core.
[0035] Preferably, a nozzle protective cover 5 is abutted below the spray hole 21, and a water outlet through hole 50 is opened in the middle of the nozzle protective cover 5, and the top of the nozzle 31 abuts against the bottom of the water outlet through hole 50. This effectively protects the top of the nozzle, avoids excessive wear, and ensures long-term use.
[0036] Preferably, the nozzle seat 2 is externally sleeved with a nozzle shell 6 , the inner wall of the nozzle shell 6 is formed with a limiting convex ring 60 , and the outer wall of the nozzle seat 2 is formed with a limiting concave ring 22 that abuts against the limiting convex ring 60 .
[0037] Preferably, the nozzle shell 6 is made of plastic.
[0038] In the above structure, the nozzle shell 6 made of plastic material protects the rotating nozzle as a whole to prevent it from hitting the nozzle seat.
[0039] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
