[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1-5 This invention provides a dynamic magnetic rotating window cleaner, comprising a first cleaning body and a second cleaning body capable of attracting each other through glass. The first cleaning body includes: First rotor mechanism; The first wiping mechanism includes a plurality of first water tanks 1 that are fixedly connected to the outer wall of the first rotor mechanism at equal intervals in the circumferential direction, and a magnetically controlled switch valve is provided in the first water tank 1. The second rotor mechanism is fixedly connected to the end of the first water storage tank 1 away from the first rotor mechanism; The second wiping mechanism includes a telescopic arm disposed on the top of the first water storage tank 1. One end of the telescopic arm is rotatably engaged with the first rotor mechanism, and the other end of the telescopic arm is fixedly connected to the second water storage tank 2. The magnetic control switch valve is disposed inside the second water storage tank 2. Water supply tank 3 is fixedly connected to the side of the first water storage tank 1 away from the glass. The first water storage tank 1 and the second water storage tank 2 are both connected to the water supply tank 3. The first wiping body has a handheld support 4 on its water tank 3, and a rotating component on its handheld support 4. The rotating component is in transmission cooperation with the second wiping mechanism. The first water tank 1, the second water tank 2, and the second rotor mechanism are respectively provided with cleaning sponges 5 on the side near the glass. The first wiping body and the second wiping body have the same structure.

[0020] In use, the first and second wiping bodies are placed on either side of the glass and positioned by magnetic attraction. The user holds the handheld bracket 4 of the first wiping body and drives the second wiping mechanism by operating the rotating component on the handheld bracket 4. This causes the telescopic arm to rotate and adjust its angle and position, moving the second water tank 2 to the appropriate cleaning area. Subsequently, the cleaning water in the water supply tank 3 is delivered to the first water tank 1 and the second water tank 2 through the connecting pipe. The magnetic control valves in each water tank precisely control the water output according to the cleaning needs, keeping the cleaning sponge 5 moist. At the same time, the first rotor mechanism drives the circumferentially distributed first water tank 1 to rotate, and the second rotor mechanism rotates synchronously. Combined with the movement of the second water tank 2 with the telescopic arm, the first water tank 1, the second water tank 2, and the cleaning sponge 5 on the second rotor mechanism can all closely adhere to the glass surface for all-round wiping. During this process, the rotating component continuously drives the second wiping mechanism to operate, and with the synchronized magnetic attraction of the first and second wiping bodies, efficient cleaning of different areas of the glass is achieved. The stains generated during cleaning are absorbed by the moist cleaning sponge 5, completing the entire window cleaning operation.

[0021] In a further optimized design, the first rotor mechanism includes a bearing 6, on which a Hellbeck array magnetic assembly 7 is coaxially fixedly connected. The Hellbeck array magnetic assemblies 7 of the first and second wiping bodies are correspondingly arranged. The first water storage tank 1 is fixedly connected to the outer bearing ring of the bearing 6. A ball groove 8 is provided at the center of the Hellbeck array magnetic assembly 7, and a ball bearing 9 is rotatably arranged in the ball groove 8. The water supply tank 3 is fixedly connected to the side of the Hellbeck array magnetic assembly 7 away from the glass.

[0022] The first and second wiping bodies are correspondingly arranged with the Hellbeck array magnetic components 7. Utilizing the strong magnetic properties of the Hellbeck array, the two wiping bodies are attracted to both sides of the glass and kept in close contact, providing a basis for synchronous movement. In the first rotor mechanism, the Hellbeck array magnetic component 7 is coaxially fixed to the inner bearing ring of the bearing 6, while the first water tank 1 is fixed to the outer bearing ring of the bearing 6. The relative rotational characteristics of the inner and outer bearing rings of the bearing 6 enable the flexible rotation of the Hellbeck array magnetic component 7 relative to the first water tank 1. Simultaneously, a ball bearing 9 is installed in the ball groove 8 at the center of the Hellbeck array magnetic component 7. The ball bearing 9 reduces the frictional resistance during rotation, improving smoothness. Furthermore, the water supply tank 3 is fixed to the side of the Hellbeck array magnetic component 7 away from the glass and rotates synchronously with it, ensuring stable water supply during rotation and preventing twisting of the water supply pipes or interruption of water supply due to rotation.

[0023] In a further optimized design, the telescopic arm includes a slide rod 10, the axis of which is perpendicular to the axis of the Helbeck array magnetic assembly 7. An annular groove 11 is formed on the side of the Helbeck array magnetic assembly 7 away from the glass. The annular groove 11 is coaxially arranged with the Helbeck array magnetic assembly 7. A locking block 12 is slidably connected within the annular groove 11, and a sliding sleeve 13 is fixedly connected to the top of the locking block 12. The slide rod 10 is rotatably connected within the sliding sleeve 13. The Helbeck array magnetic assembly 7... A toothed plate 14 is fixedly connected to the shaft. A bevel gear 15 is fixedly connected to one end of the slide rod 10. The bevel gear 15 meshes with the toothed plate 14. A threaded sleeve 16 is threadedly connected to the other end of the slide rod 10. A support block 17 is fixedly connected to the first water storage tank 1. A sliding hole 18 is opened on the support block 17. The threaded sleeve 16 is limited and slidably connected in the sliding hole 18. A rotating shaft 19 is rotatably connected to one end of the threaded sleeve 16 away from the threaded rod. The second water storage tank 2 is fixedly connected to one end of the rotating shaft 19.

[0024] When the Hellbeck array magnetic component 7 rotates, the toothed plate 14, which is coaxially fixed with it, rotates synchronously. The toothed plate 14 meshes with the bevel gear 15 at one end of the slide rod 10, transmitting rotational power to the slide rod 10, causing the slide rod 10 to rotate within the sliding sleeve 13 (the sliding sleeve 13 is slidably connected to the annular groove 11 of the Hellbeck array magnetic component 7 via a locking block 12, and the annular groove is coaxial with the Hellbeck array, ensuring that the sliding sleeve rotates synchronously with the Hellbeck array without affecting the axial movement of the slide rod). The other end of the slide rod 10 is threadedly connected to the threaded sleeve 16. When the slide rod rotates, the threaded transmission converts the rotational motion into the axial linear motion of the threaded sleeve 16. Since the threaded sleeve 16 is limited by the support block 17 of the first water tank 1 through the sliding hole 18, it cannot rotate with the slide rod and can only slide axially along the sliding hole. The end of the threaded sleeve 16 away from the slide rod is fixedly connected to the second water tank 2 through a rotating shaft 19. The axial movement of the threaded sleeve drives the rotating shaft 19 and the second water tank 2 to move synchronously, ultimately realizing the extension and retraction of the telescopic arm. In a further optimized design, a limiting block 20 is fixedly connected to the inner wall of the sliding hole 18 along the axial direction, and a limiting groove adapted to the limiting block 20 is opened on the outer wall of the threaded sleeve 16. The limiting block 20 and the limiting groove are in a limiting sliding fit.

[0025] In a further optimized scheme, the second rotor mechanism includes a permanent magnet 21 fixedly connected to the end of the first water tank 1 away from the bearing 6, and the permanent magnet 21 on the first rubbing body and the permanent magnet 21 on the second rubbing body are correspondingly arranged.

[0026] The permanent magnet 21 of the second rotor mechanism is fixed at the end of the first water tank 1 away from the bearing 6, and the permanent magnets 21 of the first and second cleaning bodies are correspondingly arranged. Utilizing the property of "opposite magnetic poles attracting each other" of permanent magnets, the permanent magnets 21 of the two cleaning bodies attract each other, further enhancing the tightness of the two cleaning bodies against the glass; at the same time, when the Heilbeck array magnetic component 7 of the first cleaning body drives the first water tank 1 and the permanent magnet 21 to rotate, the attraction force of the permanent magnets can drive the permanent magnet 21 of the second cleaning body and its corresponding components to rotate synchronously, assisting the first rotor mechanism in transmitting rotational power, reducing the synchronization error of the rotation of the two cleaning bodies, and improving the stability of the cleaning process.

[0027] In a further optimized design, the magnetically controlled switch valve includes a perforated plate 22 fixedly connected to the first water tank 1 and the second water tank 2 near the glass end. A gap is provided between the perforated plate 22 and the cleaning sponge 5. A third electromagnet 23 is provided within the gap. The third electromagnet 23 has several through holes, and the through holes on the third electromagnet 23 are offset from the water-permeable holes on the perforated plate 22. Slide plates 24 are slidably connected to the first water tank 1 and the second water tank 2, respectively. The slide plates 24 are directly opposite to and parallel to the perforated plate 22. A connecting rod 25 is fixedly connected to the slide plate 24. The connecting rod 25 passes through the perforated plate 22 and is fixedly connected to the third electromagnet 23. A spring 26 is fixedly connected between the slide plate 24 and the perforated plate 22. The spring 26 is sleeved on the connecting rod 25. In a further optimized design, a fixed rod 27 is fixedly connected to the first water tank 1 on the first wiping body, and the handheld bracket 4 is fixedly connected to the end of the fixed rod 27 away from the first water tank 1. A connecting frame 28 is rotatably connected to the fixed rod 27, and the permanent magnet 21 is fixedly connected to the connecting frame 28. A ring motor 29 is fixedly connected to the fixed rod 27, and the rotor of the ring motor 29 is fixedly connected to the connecting frame 28.

[0028] One end of the fixed rod 27 is fixed to the first water tank 1, and the other end is fixed to the handheld bracket 4, providing support for the operator and also providing an installation reference for the ring motor 29 and the connecting frame 28. The connecting frame 28 is rotatably connected to the fixed rod 27, and is also fixedly connected to the first water tank 1 and the permanent magnet 21, forming an integrated cleaning body support structure of "connecting frame-first water tank-permanent magnet". The ring motor 29 adopts a stator-fixed and rotor-rotating installation method. Its stator is fixed to the fixed rod 27, and the rotor is rigidly connected to the connecting frame 28 to ensure accurate power transmission. During operation, the ring motor 29 is started, and the rotor drives the connecting frame 28 to rotate around the axis of the fixed rod 27. The connecting frame then drives the first water tank 1, the permanent magnet 21, and the entire first cleaning body to rotate synchronously. Since the first cleaning body and the second cleaning body are tightly attached to both sides of the glass by the magnetic attraction of the permanent magnet 21, the rotational power of the first cleaning body is transmitted to the second cleaning body through the magnetic attraction force, driving the second cleaning body to rotate synchronously, realizing the rotational cleaning action of the entire cleaning body. This design uses a ring motor for direct drive, replacing the traditional indirect transmission, which improves the efficiency of rotational power transmission. At the same time, the synchronous adsorption of the permanent magnets ensures the adhesion between the two cleaning bodies and the glass during rotation, preventing deviation or detachment during rotation and ensuring uniform cleaning effect.

[0029] In a further optimized design, a safety rope 30 is fixedly connected to one side of the water tank 3 of the second cleaning unit. One end of the safety rope 30 rotates with the water tank 3 to prevent entanglement during the rotation of the water tank 3. The safety rope 30 also prevents the second cleaning unit located outside the window from falling during the cleaning process, thus avoiding danger during high-altitude operations.
