[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] Please also refer to Figure 1 and Figure 2The three-dimensional cleaning nozzle capable of biaxial rotation provided by the present invention will now be described. The three-dimensional cleaning nozzle capable of biaxial rotation comprises an intermediate connecting tube 10, an outer sleeve 20, a rotary spray mechanism 30, and a drive mechanism 40. The intermediate connecting tube 10 has a lumen with one end open, and a water outlet 11 is provided on the sidewall of the intermediate connecting tube 10. The outer sleeve 20 is sleeved onto the intermediate connecting tube 10 and rotatably connected thereto, forming an annular lumen 23 between the outer sleeve 20 and the intermediate connecting tube 10, which is connected to the water outlet 11. A connecting portion 21 is provided on the sidewall of the outer sleeve 20, and an open circular lumen is formed on the connecting portion 21, with an axis perpendicular to the axis of the outer sleeve 20. The open circular lumen is connected to the annular lumen 23. Multiple first nozzles 25 are provided on the outer wall of the outer sleeve 20, each of which is connected to the annular lumen 23. The larger end of the rotary spray mechanism 30 extends into the open circular lumen and is rotatably connected to the connecting portion 21. The rotary spraying structure 30 has a plurality of second spray heads 34. The driving structure 40 is disposed on the intermediate connecting pipe 10 and is dynamically connected to the outer sleeve 20 and the rotary spraying structure 30, and can drive the outer sleeve 20 to rotate and simultaneously drive the rotary spraying structure 30 to rotate.

[0048] The three-dimensional cleaning nozzle that can realize biaxial rotation provided by this embodiment is compared with the prior art. The intermediate connecting pipe 10 can ensure connection with the external pressure water pipe, and the outer sleeve 20 can ensure that it rotates around the intermediate connecting pipe 10 under the drive of the driving structure 40, thereby driving each first nozzle 25 and the rotating spray structure 30 to rotate around the axis of the intermediate connecting pipe 10, thereby increasing the cleaning range in the horizontal direction. The driving structure 40 can also drive the rotating spray structure 30 to rotate around the axis of the connecting portion 21, thereby rotating each second nozzle 34, while ensuring the cleaning range in the vertical direction. In this way, the coverage of the cleaning can be effectively increased, and the structural stability of the power transmission is high, effectively avoiding ineffective cleaning, ensuring the cleaning effect, and having strong practicality.

[0049] In some embodiments, the outer sleeve 20 and the intermediate connecting pipe 10 can be made of Figure 2 See the structure shown. Figure 2 The outer sleeve 20 and the intermediate connecting pipe 10 are rotatably connected through two sealing bearings 24 , and the two sealing bearings 24 are respectively located on both sides of the water outlet 11 .

[0050] The provision of the sealing bearing 24 ensures that a sealed annular cavity 23 is formed between the outer sleeve 20 and the intermediate connecting pipe 10, ensuring the water flow and preventing leakage. In addition, the provision of the sealing bearing 24 can also reduce the friction between the outer sleeve 20 and the intermediate connecting pipe 10, ensuring the stable rotation of the outer sleeve 20.

[0051] It should be noted that the water leakage refers to the cleaning fluid, which of course also includes clean water.

[0052] In some embodiments, the rotary spraying structure 30 may be configured as follows: Figure 2 The structure shown. Figure 2 The rotary spraying structure 30 includes a fixed cylinder 31, a rotating cylinder 32 and a connecting cylinder 33. The fixed cylinder 31 is located in the open circular cavity, and one end abuts against the bottom end of the open circular cavity and is connected to the annular cavity 23. The rotating cylinder 32 is sleeved on the outside of the fixed cylinder 31 and is sealed and rotatably connected to the fixed cylinder 31 through a nylon bearing 35. One end of the rotating cylinder 32 extends out of the connecting portion 21. The connecting cylinder 33 is fixedly connected to the protruding end of the rotating cylinder 32 and is connected to the rotating cylinder 32. The second nozzles 34 are arranged on the outer wall of the rotating cylinder 32 at an annular interval around the axis of the rotating cylinder 32.

[0053] The fixed cylinder 31 ensures contact with the bottom of the open circular cavity and communication with the annular cavity 23. It is rotatably connected to the rotating cylinder 32 via a nylon bearing 35. This structure prevents leakage of the cleaning fluid and reduces friction between the two. The connecting cylinder 33 is coaxially fixedly connected to the rotating cylinder 32, with its extended end sealed. The connecting cylinder 33 rotates synchronously with the rotating cylinder 32, thereby driving the rotation of each second nozzle 34, ensuring a larger vertical spray range. Furthermore, this connection structure is simple and easy to assemble and disassemble, while ensuring effective cleaning.

[0054] In some embodiments, the connecting portion 21 may be formed as follows: Figures 1 to 2 The structure shown. Figures 1 to 2 The connection portion 21 is detachably connected to a pressure cover 22 that can fix the rotating cylinder 32 . The pressure cover 22 can ensure that the position of the rotating cylinder 32 is fixed, thereby ensuring the stability of the rotating spraying structure 30 .

[0055] It should be noted that the pressure cover 22 can be connected to the connecting portion 21 by bolts, and a through hole for the rotating cylinder 32 to pass through is provided on the pressure cover 22 .

[0056] In some embodiments, the connection between the rotating drum 32 and the pressure cover 22 can be achieved by Figure 2 The structure shown. Figure 2 A rolling bearing 36 is provided between the rotating cylinder 32 and the pressure cover 22 .

[0057] The gland 22 is provided with an annular flange for limiting the outer ring of the rolling bearing 36 .

[0058] The provision of the rolling bearing 36 can reduce the friction between the rotating cylinder 32 and the pressure cover 22. At the same time, the provision of an annular flange on the pressure cover 22 can ensure that the rotating cylinder 32 and the pressure cover 22 are fixed, ensuring that during the installation process, the pressure cover 22 enters the open circular cavity synchronously, making disassembly and assembly convenient.

[0059] In some embodiments, the driving structure 40 may be configured as follows: Figures 2 to 4 The structure shown. Figures 2 to 4 The driving structure 40 includes a rotating rod 41, an impeller 42, a transmission component 43 and a linkage component 44. The rotating rod 41 is located in the tubular cavity and is coaxially arranged with the intermediate connecting tube 10. One end of the rotating rod 41 passes through one end of the intermediate connecting tube 10 and then extends out. The impeller 42 is arranged at the opening of the tubular cavity and is coaxially connected to the rotating rod 41. It can drive the rotating rod 41 to rotate as the water flows into the tubular cavity. The transmission component 43 is arranged at the end of the intermediate connecting tube 10 away from the opening and is power-connected to the rotating rod 41. The transmission component 43 can transmit the power of the rotating rod 41 to the outer sleeve 20. The linkage component 44 is connected to the intermediate connecting tube 10 and is connected to the rotating cylinder 32. It can transmit the power of the outer sleeve 20 to the rotating cylinder 32.

[0060] The intermediate connecting pipe 10 is connected to the pressure water pipe. The impeller 42 rotates under the action of the water flow, thereby driving the rotating rod 41 to rotate, and then the transmission component 43 that transmits power drives the outer sleeve 20 to rotate. At the same time, the rotating spray structure 30 is driven to rotate through the linkage component 44, so that each first nozzle 25 rotates around the axis of the intermediate connecting pipe 10, and each second nozzle 34 rotates around the axis perpendicular to the axis of the intermediate connecting pipe 10, which can ensure that the cleaning range is increased, avoid ineffective cleaning, and ensure the cleaning effect.

[0061] In some embodiments, the transmission component 43 may be configured as follows: Figures 3 and 4 The structure shown. Figures 3 and 4 The transmission component 43 includes a support frame 431, a first worm 432, a first worm wheel 433, a second worm 434, a second worm wheel 435, a transmission shaft 436, a drive gear 437, and an internal gear 438. The support frame 431 is connected to the intermediate connecting tube 10. The first worm 432 is coaxially connected to one end of the rotating rod 41. The first worm wheel 433 is rotatably mounted in the support frame 431 and meshes with the first worm 432. The second worm 434 is coaxially connected to the first worm wheel 433. The second worm wheel 435 is rotatably mounted in the support frame 431 and coaxially connected to the second worm 434 at one end. The transmission shaft 436 is rotatably mounted in the support frame 431 and coaxially connected to the second worm wheel 435 at one end. The drive gear 437 is coaxially mounted on the other end of the transmission shaft 436. The internal gear 438 is coaxially mounted on the outer sleeve 20 and has an internal tooth surface that meshes with the drive gear 437.

[0062] The first worm 432, the first worm wheel 433, the second worm 434 and the second worm wheel 435 can ensure the transmission of power to the transmission shaft 436 while avoiding interference during the power transmission process. In addition, the power is transmitted to the driving gear 437 through the transmission shaft 436, and the driving gear 437 drives the internal gear 438 to rotate, thereby realizing the driving of the outer sleeve 20. The structure is compact and the transmission stability is high, which can effectively reduce the failure rate.

[0063] In some embodiments, the linkage component 44 may be configured as follows: Figure 2 The structure shown. Figure 2 The linkage component 44 includes a crown gear 441 and a gear ring 442. The crown gear 441 is coaxially arranged on the intermediate connecting tube 10. The gear ring 442 is located in the open circular cavity and is fixedly connected to the rotating cylinder 32. The gear ring 442 meshes with the crown gear 441.

[0064] The crown gear 441 is sleeved and fixed on the middle connecting tube 10, and has an annular gear surface facing the opening of the tube cavity. During the rotation of the outer sleeve 20, the gear ring 442 engages with the crown gear 441, which drives the rotating cylinder 32 to rotate, thereby driving each second nozzle 34. The power transmission method is compact, the power transmission structure is simple, and the stability is high.

[0065] In some embodiments, the first nozzle 25 may be configured as follows: Figure 1 The structure shown. Figure 1 Each first nozzle 25 is a universal rotating nozzle. This structure can facilitate the adjustment of the direction of the nozzle, thereby improving adaptability.
