[0027] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 2 :

[0028] A rotary sprinkler comprises a joint seat 1 for water inlet and having a water inlet through hole 10 formed thereon, a sprinkler seat 2 having a rotating core cavity 20 being connected to the upper end of the joint seat 1, a spray hole 21 being provided at the top of the sprinkler seat 2, the top of the water inlet through hole 10 being communicated with the rotating core cavity 20, a tilted rotating core 3 being rotatably arranged in the sprinkler seat 2, the top of the rotating core 3 being abutted against the lower end of the spray hole 21, a rotating core through hole 30 being provided in the rotating core 3 which is communicated with each other from top to bottom, and the lower end of the rotating core through hole 30 being communicated with the rotating core cavity 20, a rectifying portion 31 consisting of a plurality of rectifying pores 310 being formed at the bottom of the rotating core through hole 30.

[0029] During the specific implementation process, the joint seat is connected to the high-pressure water pipe, which enters the rotor cavity after passing through the water inlet hole. The water in the rotor cavity enters the rotor hole 30 in the rotor core. The bottom relies on the rectification part 31 to pass the high-pressure water through the rectification pores, so that the water entering the rotor hole 30 remains linear, thereby improving the water outlet pressure effect, and has a greater cleaning power than the traditional rotary nozzle.

[0030] Preferably, a partition 11 is formed on the top of the joint seat 1 to seal the top of the water inlet through hole 10 , and a plurality of inclined water inlet holes 12 connected to the water inlet through hole 10 are formed on the outer edge of the partition 11 .

[0031] In the above structure, high-pressure water is ejected from the inclined water inlet hole 12 after entering the water inlet through hole, forming a vortex shape, driving the rotation of the rotating core, so that it forms a continuously rotating water outlet effect.

[0032] Preferably, a limiting shaft 13 extending upward is formed at the center of the upper end of the partition 11 , and the lower end of the rotating core 3 abuts against the upper end of the partition 11 and rotates circumferentially along the limiting shaft 13 .

[0033] In the above structure, the setting of the limiting shaft 13 allows the bottom of the rotating core to rotate around the limiting shaft 13, while ensuring that the top of the rotating core always keeps the lower end of the spray hole against each other.

[0034] Preferably, the rotating core 3 includes a lower rotating core body 32 and an upper rotating core body 33 fixed at the upper end thereof, the lower rotating core body 32 and the upper rotating core body 33 are provided with the rotating core through hole 30 , and the rectifying portion 31 is located at the lower end of the rotating core through hole 30 in the lower rotating core body 32 .

[0035] It is worth mentioning that the rotating core 3 is in the form of a lower rotating core body 32 and an upper rotating core body 33, which is easier to process and the rotating core 3 will also be longer, thereby achieving a better water outlet effect.

[0036] Preferably, the outer wall of the lower rotating core 32 is provided with a rotating sleeve 34, and the outer wall of the rotating sleeve 34 is provided with an "O"-shaped abutting ring 35 that abuts against the inner wall of the nozzle seat 2. The rotating sleeve 34 is provided to allow the inner wall of the rotating core cavity to abut against the rotating core cavity during the rotation process, so as to perform rotational friction and ensure the service life of the rotating core.

[0037] Preferably, a spray core 36 is inserted into the upper end of the rotating core through hole 30 in the upper rotating core body 33 , and the top of the spray core 36 abuts against the lower end of the spray hole 21 .

[0038] In the above structure, the riser core 36 is independently plugged and arranged above the upper rotating core body 32, which is convenient for the installation of the entire rotating core and also easy to replace the position.

[0039] Preferably, a positioning ring seat 22 is inserted into the lower end of the spray hole 21, and the bottom of the positioning ring seat 22 abuts against the top of the spray core 36, thereby further reducing the degree of wear on the top of the spray core.

[0040] Preferably, the upper end of the joint seat 1 is screwed with a mounting seat 14, the nozzle seat 2 is screwed to the outer wall of the mounting seat 14, and sealing rubber rings are provided between the joint seat 1 and the mounting seat 14 and between the mounting seat 14 and the nozzle seat 2 to ensure the overall sealing.

[0041] 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.
