[0031] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 3 :

[0032] A universal sprinkler, comprising a base 1 connected to a high-pressure water pipe at the bottom, a water injection chamber 10 connected to the high-pressure water pipe formed in the base 1, a partition 11 is arranged in the water injection chamber 10, a plurality of circumferentially distributed inclined through holes 110 are opened on the partition 11, a rotating shaft 2 passing through the top of the base 1 is arranged above the partition 11, a rotating wheel 3 is sleeved at the bottom of the rotating shaft 2, and a rotating blade 30 corresponding to the inclined through hole 110 is formed on the rotating wheel 3, a water channel 21 with an upper opening 20 at the top is opened in the rotating shaft 2, and a water inlet connected to the water channel 21 and the water injection chamber 10 is opened on the side wall of the rotating shaft 2 located in the base 1 22, a first bevel gear 23 is rotated on the side wall of the rotating shaft 2 extending out of the upper end of the base 1, and the bottom of the first bevel gear is fixed to the upper end of the base, a right-angle joint 4 is fixed on the rotating shaft 2 extending out of the upper end of the base 1, and a longitudinal tube 40 connected to the upper opening 20 is opened in the right-angle joint 4, a transverse tube 41 perpendicular to and connected to the longitudinal tube 40 is opened on the side wall of the right-angle joint 4, a nozzle 5 is inserted into the pipe mouth of the transverse tube 41, the nozzle 5 is sleeved with a nozzle 6, a second bevel gear 60 meshing with the first bevel gear is fixed on the nozzle 6, a nozzle core 61 is arranged at the end of the nozzle 6, and the nozzle core 61 is connected to the nozzle 5.

[0033] In the specific implementation process, high-pressure water is injected from the bottom of the base 1. After passing through the inclined through hole 110, the high-pressure water forms a vortex-shaped water flow, which acts on the rotor 30, causing the impeller 3 to rotate, and the impeller drives the rotation of the rotating shaft 2, and the rotating shaft 2 drives the rotation of the top right-angle joint. Since the first bevel gear 23 is meshed with the second bevel gear 60, the second bevel gear rotates along the first bevel gear. During the rotation process, the lateral rotation plus the longitudinal rotation of the nozzle driven by the second bevel gear 60 realizes the multi-angle rotation of the nozzle.

[0034] In the above, the water flows in from the top of the inclined through hole 110, passes through the upper end of the water injection chamber, and enters the water channel from the water inlet 22, and then flows into the nozzle 5 through the right-angle joint 4 to realize water supply to the nozzle 6, and then rotates universally, thereby improving the cleaning efficiency in the barrel.

[0035] Preferably, the rotating shaft 2 includes an upper shaft body 24 and a lower shaft body 25, and the upper end of the lower shaft body 25 is rotatably connected via a gear set 7 fixed to the lower end of the lower shaft body 25, the water channel 21 is opened in the upper shaft body 24, and a sleeve 8 for the lower shaft body 25 to pass through is formed in the base 1, and a water hole 80 communicating with each other from top to bottom is opened on the sleeve 8, the lower shaft body 25 is located above the partition 11, and the wheel 3 is fixed to the side wall of the lower shaft body 25.

[0036] In the above structure, the rotating shaft 2 is driven by the rotating wheel alone, which will cause excessive stress and make the rotating shaft 2 easy to break. The upper shaft 24 and the lower shaft 25 are adopted, and the gear set 7 is used to perform a certain deceleration to avoid the top rotating too fast, wearing the sealing ring, and preventing water leakage, thereby ensuring a longer service life.

[0037] Preferably, the gear set 7 includes a driving gear 250 formed on the top of the lower shaft body 25, and a planetary gear set 70 is arranged on the driving gear 250. The planetary gear set 70 includes a rotating disk 71. The upper part of the rotating disk 71 is fixedly connected to the lower end of the upper shaft body 24, and the lower part of the rotating disk 71 is rotatably connected with a plurality of planetary gears 72 matched with the driving gear 250. The inner wall of the base 1 is formed with a gear ring 12 matched with the plurality of planetary gears 72.

[0038] Preferably, there are two planetary gear sets 70 , and the two planetary gear sets 70 are arranged one above the other.

[0039] In the above structure, the gear set 7 is in the form of a planetary gear set, which has a good deceleration effect. It is worth mentioning that the two sets of planetary gear sets 70 are arranged in such a way that the top of the bottom rotating disk is formed with a driving gear 250 that matches with a plurality of planetary gears 72 at the lower end of the top rotating disk, and the top of the top rotating disk is fixed to the lower end of the lower shaft 25.

[0040] Preferably, the base 1 is composed of a first base 13, a second base 14, a third base 15 and a fourth base 16 which are bolted together, a mounting hole 130 for the upper shaft body 24 to pass through is formed in the middle of the first base 13, the gear ring 12 is formed on the inner wall of the second base 14, the sleeve 8 is formed on the inner wall of the third base 15, a threaded cavity 160 for connecting to a high-pressure water pipe is formed in the fourth base 16, and the partition plate 11 is covered on top of the threaded cavity 160.

[0041] In the above structure, if the base 1 is formed in one piece, it will bring great challenges to the processing difficulty. However, adopting a split structure and fixing it with bolts through it can reduce the difficulty of assembly and production.

[0042] Preferably, a cylindrical filter screen 17 is provided in the threaded cavity 160. This structure can filter impurities in the high-pressure water pipe to avoid blockage in the universal nozzle.

[0043] Preferably, a socket 710 is formed on the top of the rotating disk 71, and the bottom of the upper shaft body 24 is inserted into the socket 710 and fixed by a pin.

[0044] Preferably, a bearing is provided between the nozzle 5 and the second bevel gear 60 to reduce friction during rotation.

[0045] In the above structure, a shell is wrapped around the outer wall of the right-angle joint 4 to protect the first bevel gear and the second bevel gear from corrosion.

[0046] 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.
