Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

Each technical feature in the creation of the present utility model can be interactively combined without conflicting with each other, referring to Figures 1-7 .

[0030] A lifting mop mechanism for a floor sweeper, comprising a gearbox 1. Inside the gearbox 1, there are a driving motor 2, a first rotating shaft 31, a second rotating shaft 32, a third rotating shaft 33, a fourth rotating shaft 34 and a rotating sleeve 5. An output gear 21 is provided on the output shaft of the driving motor 2. A first rotating gear 41 and a second rotating gear 42 are provided on the first rotating shaft 31. A third rotating gear 43 and a fourth rotating gear 44 are provided on the second rotating shaft 32. A fifth rotating gear 45 and a sixth rotating gear 46 are provided on the third rotating shaft 33. A seventh rotating gear 47 is provided on the fourth rotating shaft 34. An eighth rotating gear 48 is provided on the rotating sleeve 5. The output gear 21 meshes with the first rotating gear 41. The second rotating gear 42 meshes with the third rotating gear 43. The fourth rotating gear 44 meshes with the fifth rotating gear 45. The sixth rotating gear 46 meshes with the seventh rotating gear 47. The seventh rotating gear 47 meshes with the eighth rotating gear 48. An elevating shaft 6 is provided inside the rotating sleeve 5. An external thread 61 is provided on the outer wall of the elevating shaft 6. An internal thread 51 matching the external thread 61 is provided on the inner wall of the rotating sleeve 5. The external thread 61 and the internal thread 51 cooperate with each other to make the elevating shaft 6 threadedly connected to the rotating sleeve 5. The lower end of the elevating shaft 6 extends to the bottom of the gearbox 1, and a lifting sleeve 7 is provided on the part of the elevating shaft 6 extending to the bottom of the gearbox 1. The lifting sleeve 7 is used for installing a mop. A damping sleeve 8 sleeving the outer periphery of the lifting sleeve 7 is provided at the bottom of the gearbox 1. The damping sleeve 8 is in damping contact with the outer wall of the lifting sleeve 7.

[0031] During specific applications, when the floor sweeper starts working and needs to use the mopping device to mop the floor, the drive motor 2 starts working. The drive motor 2 drives the output gear 21 to rotate. The output gear 21 drives the first rotating gear 41 to rotate. The first rotating gear 41 drives the second rotating gear 42 to rotate. The second rotating gear 42 drives the third rotating gear 43 to rotate. The third rotating gear 43 drives the fourth rotating gear 44 to rotate. The fourth rotating gear 44 drives the fifth rotating gear 45 to rotate. The fifth rotating gear 45 drives the sixth rotating gear 46 to rotate. The sixth rotating gear 46 drives the first rotating gear 47 to rotate. The seventh rotating gear 47 drives the eighth rotating gear 48 to rotate. The eighth rotating gear 48 drives the rotating sleeve 5 to rotate. Since there is a damping contact between the damping sleeve 8 and the lifting sleeve 7, the damping sleeve 8 has a damping force on the lifting sleeve 7. And, since the lifting sleeve 7 is fixedly connected to the lifting shaft 6. Therefore, when the rotating sleeve 5 rotates, the lifting sleeve 7 and the lifting shaft 6 do not rotate synchronously with the rotating sleeve 5. At this time, since the rotating sleeve 5 and the lifting shaft 6 are threadedly connected through the internal thread 51 and the external thread 61, the threaded connection structure formed by the external thread 61 and the internal thread 51 can drive the lifting shaft 6 to descend. The lifting shaft 6 drives the lifting sleeve 7 to descend synchronously. The mop installed at the lower end of the lifting sleeve 7 can descend to the preset mopping height to perform the mopping work. When the mopping is completed, the drive motor 2 drives the rotating sleeve 5 to rotate in the reverse direction, and then can drive the lifting shaft 6 and the lifting sleeve 7 to rise, completing the upward storage work of the mop.

[0032] In this embodiment, a descending limit plate 62 is fixedly arranged at the upper end of the lifting shaft 6. A first limit block 63 is arranged on the descending limit plate 62. A second limit block 52 for cooperating with the first limit block 63 is arranged along the rotating sleeve 5. When the lifting shaft 6 descends to the lowest point, the first limit block 63 and the second limit block 52 limit each other to prevent relative rotation between the lifting shaft 6 and the rotating sleeve 5. When the lifting shaft 6 descends to the preset lowest point, due to the limiting structure formed by the first limit block 63 and the second limit block 52, therefore, the rotating sleeve 5 and the lifting shaft 6 will rotate synchronously. During the rotation of the lifting shaft 6, the lifting shaft 6 drives the mop to perform a rotating mopping action through the lifting sleeve 7, and then can drive the mop to rotate through the driving motor 2 to complete the mopping action.

[0033] In this embodiment, a third limiting block 71 is provided along the upper edge of the lifting sleeve 7, and a fourth limiting block 53 that cooperates with the third limiting block 71 is provided along the lower edge of the rotating sleeve 5. When the lifting sleeve 7 rises to the highest point, the third limiting block 71 and the fourth limiting block 53 limit each other to prevent relative rotation between the lifting sleeve 7 and the rotating sleeve 5. When the lifting shaft 6 rises to the preset highest point, due to the limiting structure formed by the third limiting block 71 and the fourth limiting block 53, the rotating sleeve 5 and the lifting sleeve 7 will rotate synchronously.

[0034] In some embodiments, a guiding sleeve 10 extends upward from the gearbox 1, and the descending limiting plate 62 is disposed in the guiding inner cavity of the guiding sleeve 10 and can move up and down along the guiding inner cavity of the guiding sleeve 10.

[0035] In some embodiments, a through groove 81 that penetrates both the inside and outside is formed in the side of the damping sleeve 8, and a damping elastic piece 82 is disposed in the through groove 81. The inner wall of the damping elastic piece 82 is in frictional contact with the outer wall of the lifting sleeve 7 to form a damping force on the lifting sleeve 7. Specifically, in this embodiment, the damping elastic piece 82 includes a contact portion in the middle and elastic portions on both sides. The contact portion is in contact with the outer wall of the lifting sleeve 7, and the elastic portions provide a tensioning elastic force to the contact portion. By adjusting the elastic force of the elastic portions, the contact pressure between the contact portion and the lifting sleeve 7 can be adjusted, and thus the damping magnitude can be adjusted. Specifically, when implementing, a suitable damping value can be set as needed.

[0036] In some embodiments, a first stepped position 111 and a second stepped position 121 are provided inside the gearbox 1. A first rotating shaft sleeve 91 is disposed on the first stepped position 111, and a second rotating shaft sleeve 92 is disposed on the second stepped position 121. The rotating sleeve 5 can be actively disposed inside the gearbox 1 through the first rotating shaft sleeve 91 and the second rotating shaft sleeve 92.

[0037] In some embodiments, both the output gear 21 and the first rotating gear 41 are helical gears, and the eighth rotating gear 48 and the rotating sleeve 5 are integrally formed parts. Such integrally formed parts can improve the overall structure, reduce the number of components, and improve the assembly efficiency. In some other embodiments, the eighth rotating gear 48 and the rotating sleeve 5 can also adopt a split structure.

[0038] In some embodiments, the first rotating gear 41 and the second rotating gear 42 together form a first double gear, the third rotating gear 43 and the fourth rotating gear 44 together form a second double gear, and the fifth rotating gear 45 and the sixth rotating gear 46 together form a third double gear. By setting the form of double gears, the overall structure can be improved, the number of components can be reduced, and the assembly efficiency can be improved.

[0039] In some embodiments, the gearbox 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 is provided with docking ridges on the end face where it docks with the lower housing 12, and the lower housing 12 is provided with docking grooves on the end face where it docks with the upper housing 11. The docking ridges are snapped into the docking grooves, enabling the upper housing 11 and the lower housing 12 to cooperate to form a gearbox 1 with an internal cavity, and the upper housing 11 and the lower housing 12 are fixedly connected by screws.

[0040] In some embodiments, the damping sleeve 8 and the lower housing 12 are integrally formed, and the lifting shaft 6 and the lifting sleeve 7 are integrally formed. By setting the lifting shaft 6 and the lifting sleeve 7 into an integrally formed structure, the overall structure can be improved, the number of components can be reduced, and the assembly efficiency can be enhanced.

[0041] Based on the above-mentioned lifting mop mechanism of the floor sweeper, the present invention also provides:

Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
