[0022] like Figures 1 to 5 The cleaning brush drive mechanism shown includes a transmission gear 1, an eccentric tooth 2, a pull ring 3, a pull rod 4, a brush disc 5 and a mounting block 6. The mounting block 6 is provided on one side of the brush disc 5, and bristles 7 are provided on the other side of the brush disc 5.

[0023] One end of the transmission gear 1 is connected to the driving motor, and the other end is engaged with the eccentric tooth 2. The eccentric tooth 2 is arranged on the rotating shaft 8. In this application, the rotating shaft 8 is located at the center position of the eccentric tooth 2, and the eccentric tooth 2 rotates along the rotating shaft 8. An eccentric wheel 9 is provided on the eccentric tooth 2, and the eccentric wheel 9 is also sleeved on the rotating shaft 8. The eccentric wheel 9 rotates along the rotating shaft 8. A pull ring 3 is provided on the outer ring of the eccentric wheel 9. The eccentric wheel 9 realizes the pushing and pulling action of the pull ring 3 during the rotation process. The pull ring 3 is connected to one end of the pull rod 4, and the other end of the pull rod 4 is connected to the mounting block 6.

[0024] When the cleaning brush driving mechanism of the present invention is in use, the driving motor is first started, and the driving motor drives the transmission gear 1 to rotate. Since the transmission gear 1 and the eccentric gear 2 are meshed, and the eccentric gear 2 is arranged on the rotating shaft 8, the transmission gear 1 drives the eccentric gear 2 to rotate along the rotating shaft 8. The eccentric gear 2 is provided with an eccentric wheel 9, and the eccentric wheel 9 is also sleeved on the rotating shaft 8. During the rotation of the eccentric gear 2, the eccentric wheel 9 is driven to rotate along the rotating shaft 8. Since the outer ring of the eccentric wheel 9 is provided with a pull ring 3, the eccentric wheel 9 continuously pushes and pulls the pull ring 3 during the rotation along the rotating shaft 8, and then drives the pull rod 4 to push and pull through the pull ring 3, and finally realizes that the pull rod 4 drives the mounting block 6 and the brush disc 5 to push and pull, so that the bristles on the brush disc 5 complete the counterclockwise and clockwise rotation action with the overall push-pull action of the brush disc 5, and realizes that the brush disc 5 drives the bristles to rub and clean the surface of the object.

[0025] The cleaning brush driving mechanism of the present invention drives the eccentric teeth 2 through the transmission gear 1, thereby realizing the rotation of the eccentric wheel 9 on the eccentric teeth 2 along the rotating shaft 8, and during the rotation of the eccentric wheel 9, it drives the pull ring 3 and the pull rod 4 to realize the push-pull action, and finally drives the mounting block 6 and the brush disc 5 to realize the counterclockwise and clockwise rotation of pushing and pulling through the pull rod 4, so that the bristles clean the surface of the object; compared with the original clockwise or counterclockwise rotation of the brush by the eccentric wheel hitting the contact fork, the driving mechanism of the present application is tightly connected, the rotation of the eccentric wheel drives the pull ring to push and pull, and then drives the brush disc to rotate, there is no impact action during the process of the eccentric wheel driving the pull ring to push and pull, and there is no noise during the rotation of the eccentric wheel, which greatly extends the service life of the driving mechanism, while reducing the generation of noise, avoiding noise trouble to the user, and improving comfort during use.

[0026] As a preferred embodiment, the cleaning brush drive mechanism of the present application further includes an upper shell 10 and a lower shell 11, wherein the upper shell 10 and the lower shell 11 are connected to form an installation cavity; the transmission gear 1, the eccentric gear 2, the pull ring 3, and the pull rod 4 are all arranged in the installation cavity; the upper shell 10 and the lower shell 11 are used to protect the various components in the installation cavity, thereby extending the service life of each component;

[0027] The lower shell 11 is provided with a mounting hole 1101. The mounting block 6 and the mounting hole 1101 are both strip-shaped structures. The mounting block 6 extends from the mounting hole 1101 into the mounting cavity; and the mounting block 6 extending into the mounting cavity is staggered with the mounting hole 1101. The shape of the mounting block 6 in this application matches the shape of the mounting hole 1101, and the size of the mounting hole 1101 is slightly larger than the mounting block 6, so that the mounting block 6 can be easily extended into the mounting cavity from the mounting hole 1101. After the mounting block 6 is extended into the mounting cavity, an external force rotates the mounting block 6. Since the mounting block 6 is set on the brush disc 5, the brush disc 5 rotates synchronously during the rotation of the mounting block 6. The mounting block 6 in this application is a strip-shaped structure. After the mounting block 6 is rotated, an angle is formed between the mounting block 6 and the mounting hole 1101, so that the mounting block 6 and the mounting hole 1101 are staggered, thereby preventing the mounting block 6 from falling out of the mounting hole 1101 and ensuring the stability of the mounting block 6 in the mounting cavity.

[0028] As a preferred embodiment, the bottom end of the mounting block 6 in the present application is connected to the connecting post 12, and the other end of the connecting post 12 is connected to the brush disc 5. The length of the connecting post 12 between the mounting block 6 and the brush disc 5 matches the depth of the mounting hole 1101. That is, in the present application, after the mounting block 6 passes through the mounting hole 1101, an external force drives the mounting block 6 to drive the brush disc 5 to rotate along the mounting hole 1101. At this time, the connecting post 12 also rotates synchronously along the mounting hole 1101. The length of the connecting post 12 between the mounting block 6 and the brush disc 5 matches the depth of the mounting hole 1101, ensuring that the mounting block 6 extends into the mounting cavity after passing through the mounting hole 1101.

[0029] As a preferred embodiment, a side mounting groove 601 is provided on the side wall of the mounting block 6, and a top mounting groove 602 is provided on the top of the mounting block 6; the side mounting groove 601 and the top mounting groove 602 are connected, and the side mounting groove 601 and the top mounting groove 602 pass through one end of the mounting block 6;

[0030] The pull rod 4 is provided with a mounting post 401, which is matched with the side mounting groove 601 and the top mounting groove 602. In the present application, the mounting post 401 on the pull rod 4 extends from the side mounting groove 601 and the top mounting groove 602 into the mounting block 6, thereby connecting the pull rod 4 and the mounting block 6. This facilitates the push and pull of the mounting block 6 by the pull rod 4, thereby achieving counterclockwise and clockwise rotation of the brush plate 5, and achieving surface cleaning of the object by the bristles 7.

[0031] As a preferred embodiment, the mounting block 6, the connecting column 12 and the brush disc 5 are connected by a brush head shaft 13. The brush head shaft 13 extends out of the mounting block 6. A brush head shaft sleeve 14 is provided at the outer ring of the brush head shaft extending out of the mounting block 6. A metal sheet 15 is also provided between the brush head shaft sleeve 14 and the mounting block 6. The metal sheet 15 is matched and located at the top of the top mounting groove 602.
