Both ends of water pipe 1 are fixedly connected with fixed block one 3, and the role of fixed block one 3 is to stably fix the connecting point of water pipe 1 and whole component, ensures the stability of water pipe 1. Fixed block one 3 bottom is fixedly connected with connecting shell 4, and connecting shell 4 provides support and connecting action for the whole structure, ensures the accurate butt joint of other components, and one side of the inner wall of connecting shell 4 is fixedly connected with square fixed plate 6, and the role of square fixed plate 6 is to provide support for the fixation of motor 8 and keep the stability of structure. One side of square fixed plate 6 is fixedly connected with fixed block two 7, and motor 8 is fixedly connected in fixed block two 7. The role of motor 8 is to provide power, drives connecting plate 10 through its output end, to push the motion of whole swing component. The output end of motor 8 is fixedly connected with connecting plate 10, and connecting plate 10 is used to transmit the rotary power of motor to connecting block 11, to realize the swing action, and connecting block 11 is rotatably connected in connecting plate 10. The both sides of connecting block 11 are slidably connected with arc fixed plate 12. The role of arc fixed plate 12 is to provide guidance for swing assembly, to make connecting block 11 can stably slide in arc track. One side of arc fixed plate 12 is fixedly connected on the outer wall of connecting frame 13, to ensure the firm connection between connecting frame 13 and other components. Rotating shaft 14 is rotatably connected in connecting frame 13, and rotating shaft 14 provides support for swing component and makes whole component can freely swing around rotating shaft 14, and the outer wall of rotating shaft 14 is fixedly connected with fixed frame 9, and one side of fixed frame 9 is fixedly connected on the outer wall of square fixed plate 6, to further enhance the firmness between connecting frame 13 and square fixed plate 6, to ensure the stability of component during working process. One side of connecting frame 13 is fixedly connected with fixed ring one 15, and the inner wall of fixed ring one 15 is fixedly connected on the outer wall of connecting pipe 2, and the role of fixed ring one 15 is to ensure the firm connection between connecting frame 13 and connecting pipe 2, to prevent loosening due to swing force, and a plurality of recesses are formed in the bottom of connecting shell 4, and the recesses provide swing space for connecting pipe 2, to make connecting pipe 2 can realize flexible swing under the support of fixed ring one 15. The design of recess ensures that the component can keep stable during swing process, avoids the abrasion of assembly due to excessive motion resistance. The overall structure guarantees the effective swing of sprinkler head 5 through these precise designs, to improve the spraying range, to ensure that the equipment can evenly cover the required area;

[0033] Specifically, during the use of the device, first, the water flow is conducted to the spray head 5 at one end of the connecting pipe 2 through the water pipe 1, ensuring the stable supply of water source and providing sufficient water for the spraying process. Subsequently, the motor 8 is started, and the motor 8 drives the connecting plate 10 to rotate through its output end. The rotation of the connecting plate 10 can effectively transmit power and push the connecting block 11 to reciprocate on the inner wall of the arc-shaped fixed plate 12. In the reciprocating process of the connecting block 11, the connecting frame 13 will bear the power transmitted by the connecting block 11 and reciprocate around the rotating shaft 14 as the center. The rotation of the rotating shaft 14 provides stable rotating support for the connecting frame 13, ensuring that it will not jam or deviate during the work process. Through this precise motion transmission, the reciprocating movement of the connecting frame 13 will transmit the motion force to the outer wall of the spray head 5, and then make the spray head 5 produce synchronous reciprocating movement. The reciprocating movement of the spray head 5 can effectively expand its spraying range, ensuring that the sprayed liquid can cover a wider area, thereby improving the working efficiency of the device.

[0034] Referring to Figure 1 and Figure 4The sealing assembly includes a rubber ring 17 located on the outer wall of the shower head 5, which plays a sealing and prevents water leakage role, to ensure the stable operation of the components. The outer wall of the fixed block 3 is fixedly connected with a fixed ring 16, and the fixed ring 16 is used to firmly fix the rubber ring 17 on the outer wall of the shower head 5, so as to maintain the sealing property. The fixed ring 16 is fixedly connected with the rubber ring 17 at the top, and the rubber ring 17 provides an effective sealing interface at the connection to avoid water leakage from the gap between the shower head 5 and the connecting pipe 2. The rubber ring 17 is fixedly connected with a plurality of rubber strips 18 at the top, which can increase the contact area and enhance the sealing effect, thereby reducing the possibility of water leakage. The rubber strips 18 are in close contact with the inside of the rubber ring 19, which further enhances the stability of the sealing structure and ensures that there is no gap or gap between the two, so that the entire sealing component achieves the ideal leakage prevention effect. The outer wall of the connecting pipe 2 is fixedly connected with a fixed ring 21, which not only provides fixed support for the rubber ring 20, but also prevents displacement of the assembly during use. The inner wall of the fixed ring 21 is fixedly connected with the rubber ring 20, which provides another layer of sealing protection for the fixed ring 21, further enhancing the sealing effect and avoiding water leakage through the joint. The inner wall of the rubber ring 20 is provided with a rubber ring 19, which is used to form a close contact with the rubber ring 17 to ensure that there is no leakage point. The inner wall of the fixed ring 21 is provided with a spring 22, one end of which is fixedly connected to the top of the rubber ring 19. The spring 22 is used to provide continuous pressure to ensure that the rubber ring 19 is always in close contact, thereby avoiding sealing loosening caused by long-term use. The other end of the spring 22 is fixedly connected to the inner wall of the fixed ring 21, which ensures that the spring 22 can provide sufficient counterforce when needed, so that the rubber ring 19 always maintains a stable sealing state, thereby enhancing the reliability of the overall sealing component.

[0035] Specifically, during installation of the device, the threaded pipe at one end of the spray head 5 is connected and fixed with the connecting pipe 2, which ensures the stability and sealing between the spray head 5 and the connecting pipe 2. In this way, water flow can be effectively conducted to ensure the normal operation of the components. After connection and fixation, the rubber ring 1 7 at the top of the fixed ring 2 16 is pushed to move along the specified path to the bottom of the rubber ring 2 19, which realizes effective sealing treatment between the spray head 5 and the connecting pipe 2, prevents water leakage, and ensures the stability of the water pressure of the components. At the same time, the rubber strip 1 8 will enter the hole inside the rubber ring 2 19 with the movement of the rubber ring 1 7, further enhancing the contact area between the rubber ring 1 7 and the rubber strip 1 8. The increase of the contact area helps to improve the sealing effect and reduce the leakage of water flow through the interface. In addition, the rubber ring 1 7 will also push the spring 2 2 to be extruded during movement. The spring 2 2 rebounds the extrusion force to one side through its elasticity, thereby strengthening the close-fitting density between the rubber ring 1 7 and the rubber ring 2 19. Through this design, the components can achieve stronger sealing performance to prevent water leakage. In addition to the above sealing measures, the rubber ring 3 20 is also used to seal between the rubber ring 2 19 and the inner wall of the fixed ring 3 21. The addition of the rubber ring 3 20 further improves the sealing, ensuring that the water flow is completely isolated in the pipe components of the device, avoiding any unnecessary leakage. The optimized design of the entire sealing component enhances the sealing effect of the device, effectively guarantees the stability and safety of the device in a high-pressure environment, and also prolongs the service life of the device and reduces the maintenance cost.

[0036] Working principle: during use of the device, the water pipe 1 conducts water flow to the spray head 5 at one end of the connecting pipe 2, and then the motor 8 is started to drive the connecting plate 1 0 to rotate, thereby pushing the connecting block 1 1 to reciprocally slide in the inner wall of the arc-shaped fixed plate 1 2. In this process, the connecting frame 1 3 will reciprocally swing around the pivot 1 4, and the movement force is transmitted to the outer wall of the spray head 5, so that the spray head 5 also synchronously swings, expanding the spraying range of the spray head 5.

[0037] During installation of the device, the threaded pipe at one end of the spray head 5 is connected and fixed with the connecting pipe 2, thereby pushing the rubber ring 1 7 at the top of the fixed ring 2 16 to move to the bottom of the rubber ring 2 19, thereby sealing between the spray head 5 and the connecting pipe 2. At the same time, the rubber strip 1 8 will move to the hole inside the rubber ring 2 19, enhancing the contact area between the rubber ring 1 7 and the rubber strip 1 8. The rubber ring 1 7 will push the spring 2 2 to be extruded at the same time, and the spring 2 2 rebounds the extrusion force to one side, enhancing the close-fitting density between the rubber ring 1 7 and the rubber ring 2 19. At the same time, the rubber ring 3 20 is used to seal between the rubber ring 2 19 and the inner wall of the fixed ring 3 21, enhancing the sealing effect of the device.
