[0045] Please refer to Figure 1 -2, Figure 1 is the exploded view of the cleaning joint of the present invention; Figure 2It is a cross-sectional view of the cleaning joint of the present invention. Specifically, the cleaning joint 10 of the present invention includes an inner shell 1, a rotating member 2, a cover plate 3 and an outer shell 4; the inner shell 1 has a first channel 11; the rotating member 2 has a second channel 23, the first end of the rotating member 2 penetrates through the inner shell 1 and rotates around the axis of the second channel 23, and the first channel 11 communicates with the second channel 23; at least one blade 24 that is inclined or bent relative to the axis of the second channel 23 is formed on the inner side of the second channel 23; the cover plate 3 is installed at the second end of the rotating member 2, the cover plate 3 is formed with a water outlet hole 31 communicating with the second channel 23, and a brush 32 is provided on the side of the cover plate 3 facing away from the second channel 23; the outer shell 4 is hollow inside and has openings at both ends, the outer shell 4 is sleeved outside the rotating member 2 to prevent the rotating member 2 from causing harm to the user during rotation, and the inner side of the first end of the outer shell 4 is connected to the outer side of the inner shell 1.

[0046] Among them, the cross-section of the above-mentioned first channel 11 can be circular, square or other polygons, and the cross-section of the first channel 11 in the embodiment of the present invention is preferably circular. The first channel 11 extends along its axis and penetrates through the upper and lower ends of the inner shell 1. The first end of the rotating member 2 can rotate by being inserted into the lower end of the inner shell 1 and being limited in the first channel 11. The axis of the first channel 11 and the axis of the second channel 23 are on the same straight line, that is, the rotating member 2 rotates relative to the inner shell 1 around the axis of the first channel 11. The number of the water outlet holes 31 and the brushes 32 is multiple.

[0047] Based on the structure of the above-mentioned cleaning joint 10, when water flows into the first channel 11, it is set that the water flow direction is the same as the axis of the first channel 11. After the water flow passes through the second channel 23, it flows out from the water outlet hole 31. Since there is a certain included angle between the water flow direction and the surface of the blade 24, the water flow forms an impact force on the blade 24, and the rotating member 2 is driven to rotate by the turbine principle, so that the cover plate 3 with the brush 32 rotates rapidly. When the water flow flowing out from the water outlet hole 31 flushes the surface of the tableware, the rotating brush 32 can scrape the surface of the tableware, scrape off the oil stains or dirt from the surface of the tableware and wash them away with the water flow, improving the cleaning effect and cleaning efficiency of the tableware, and effectively removing the oil stains or dirt on the tableware.

[0048] Furthermore, in order to make the overall structure more beautiful, the end face of the second end of the rotating member 2 and the end face of the second end of the outer shell 4 are on the same plane. The outer peripheral side of the cover plate 3 extends outward so that the cover plate 3 is connected to the second end of the outer shell 4, so that the cover plate 3 completely covers the opening of the outer shell 4 after being connected to the rotating member 2, and at the same time, the number of the brushes 32 can be increased.

[0049] Further, in order to improve the rotational stability of the second end of the rotating member 2, a first bearing 5 is provided between the outer side of the second end of the rotating member 2 and the inner side of the second end of the housing 4. The first bearing 5 is a commonly used bearing structure in the prior art, and its description is omitted here. The inner ring of the first bearing 5 is sleeved on the outer side of the second end of the rotating member 2 by interference fit, and the outer ring of the first bearing 5 is embedded in the inner side of the second end of the housing 4 by interference fit, so that the relative rotational friction between the second end of the rotating member 2 and the second end of the housing 4 is reduced through the first bearing 5.

[0050] Please refer to Figure 2 、 4 , Figure 4 FIG. is a schematic structural diagram of the cover plate of the present invention. In the embodiment of the present invention, an annular protrusion 33 inserted into the second channel 23 is formed on one side of the cover plate 3 facing the second channel 23, and the annular protrusion 33 is used for positioning when the cover plate 3 is assembled with the rotating member 2. In addition, since there will be a certain gap between the outer side of the annular protrusion 33 and the inner side of the second channel 23, resulting in water leakage, a first sealing ring 6 is provided between the outer side of the annular protrusion 33 and the inner side of the second channel 23. The first sealing ring 6 can be a rubber ring or a silica gel ring, etc. In this way, the first sealing ring 6 is used to fill the gap between the outer side of the annular protrusion 33 and the inner side of the second channel 23, playing a role of waterproof sealing.

[0051] Further, in order to improve the assembly convenience and stability between the cover plate 3 and the rotating member 2, a positioning groove 35 is formed on the annular protrusion 33. The number of the positioning grooves can be multiple. In the embodiment of the present invention, it is preferably four, and the four positioning grooves are arranged at intervals along the circumferential direction of the annular protrusion 33. Among them, at least two relatively spaced convex blocks 34 are provided on the surface of the annular protrusion 33, and the adjacent two convex blocks 34 form the positioning groove 35. Correspondingly, please refer to Figure 3 , Figure 3 FIG. is a schematic structural diagram of the rotating body of the present invention. A positioning protrusion 25 that cooperates with the positioning groove 35 for positioning is provided on the inner side of the second channel 23. The number of the positioning protrusions 25 is the same as the number of the positioning grooves 35, and the position and shape of the positioning protrusion 25 are matched with the position and shape of the positioning groove 35, so as to realize the assembly positioning between the cover plate 3 and the rotating member 2 through the concave-convex fit.

[0052] Further, please refer to Figure 3 FIG., in order to enable the water flow to stably and continuously drive the rotating member 2 to rotate in one direction, the number of the blades 24 in the embodiment of the present invention is multiple. The multiple blades 24 are arranged circumferentially along the axis of the second channel 23, and the inclination or bending direction of each blade 24 is the same as that of the axis of the second channel 23; one sides of the multiple blades 24 are respectively fixedly connected to the inner side of the second channel 23, and the other sides of the multiple blades 24 are close to each other to define and form a connecting column 26, so that the multiple blades 24 are connected together to form a turbine structure, and the overall structure is more firm and stable.

[0053] In an embodiment of the present invention, please refer to Figure 3 -4. In order to detachably connect the cover plate 3 to the rotating member 2, a through hole 36 is provided at the center position of the cover plate 3, and a threaded hole 261 is provided on the end face of the connecting column 26. A threaded fastener 7 such as a bolt or a screw passes through the through hole 36 and is connected to the threaded hole 261, so as to facilitate the user to replace the cover plate 3 and improve the recycling rate of the cleaning joint 10. In other embodiments, the cover plate 3 can be fixed to the rotating member 2 by means of adhesion.

[0054] Please refer to Figure 2 -3. In an embodiment of the present invention, the rotating member 2 includes a rotating shaft 21 and a rotating body 22; the first end of the rotating shaft 21 passes through the first channel 11 and rotates around the axis of the second channel 23, the second end of the rotating shaft 21 protrudes outside the first channel 11 and is connected to the first end of the rotating body 22, and the second channel 23 sequentially passes through the rotating shaft 21 and the rotating body 22; the blades 24 are arranged inside the rotating body 22, and the cover plate 3 is connected to the second end of the rotating body 22. Specifically, the first end of the rotating shaft 21 is inserted into the first channel 11 through the lower opening of the first channel 11, and the second end of the rotating shaft 21 passes through the lower opening of the first channel 11 and protrudes outside the first channel 11.

[0055] Among them, the rotating body 22, the connecting column 26 and the plurality of blades 24 are integrally formed by an injection molding process to make the overall structure more firm.

[0056] In order to limit the first end of the rotating shaft 21 to be fixed in the first channel 11, a first annular fence 211 is provided on the outer side of the first rotating shaft 21, and a second annular fence 12 is provided on the inner side of the lower end of the first channel 11. The first annular fence 211 and the second annular fence 12 abut against each other, thereby limiting the first end of the rotating shaft 21 in the first channel 11. Further, in order to provide a second bearing 8 between the first annular fence 211 and the second annular fence 12, the inner ring of the second bearing 8 is sleeved on the outer side of the rotating shaft 21, and the outer ring of the second bearing 8 is embedded in the inner side of the first channel 11, so that the relative rotational friction between the rotating shaft 21 and the inner shell 1 is reduced through the second bearing 8.

[0057] Further, in order to prevent water flow from flowing out of the gap between the rotating shaft 21 and the inner shell 1 into the outer shell 4, a second rubber ring is provided between the outer side of the rotating shaft 21 and the inner side of the first channel 11. The second rubber ring can be a rubber ring or a silica gel ring, etc. In this way, the second sealing ring 9 is used to fill the gap between the outer side of the rotating shaft 21 and the inner side of the first channel 11, playing a role of waterproof sealing.

[0058] Furthermore, the first end of the swivel body 22 and the second end of the rotating shaft 21 can be connected by threads, and glue is used for reinforcement at the connection to prevent water leakage. In the embodiment of the present invention, the swivel body 22 is in a horn shape, and the cross-section of the swivel body 22 gradually increases in the direction from its first end to the second end. Correspondingly, the outer shell 4 is also in a horn shape to cooperatively wrap around the outside of the swivel body 22.

[0059] In summary, the embodiment of the present invention provides a cleaning joint 10. The cleaning joint 10 is installed at the outlet of a faucet. Water flows through the first channel 11 and the second channel 23 in sequence and then flows out from the water outlet hole 31. During this process, the water flow forms an impact force on the blades 24, and drives the rotating member 2 to rotate through the turbine principle, so that the cover plate 3 with the brush 32 rotates rapidly. When the water flow flowing out from the water outlet hole 31 flushes the surface of tableware, the rotating brush 32 can scrape the surface of the tableware, scrape off oil stains or dirt from the surface of the tableware and wash them away with the water flow, improving the cleaning effect and cleaning efficiency of the tableware, effectively removing the oil stains or dirt on the tableware, and enhancing the user experience.
