It will be appreciated that the actuator 12 is held in abutment with the follower 32 to transmit movement, the angle by which the actuator 12 rotates about the first centre of rotation 11 being approximately equal to the angle by which the follower 32 rotates about the second centre of rotation 31. With the ground brush main body 200, the first rotating assembly 1 is abutted against the driven piece 32 arranged on the second rotating assembly 3 through the actuating piece 12 to drive the second rotating assembly 3 to rotate, so that the angular speed of the first rotating assembly 1 rotating around the first rotating center line 11 is approximately equal to the angular speed of the second rotating assembly 3 rotating around the second rotating center line 31, and the first rotating assembly 1 can be partially moved into or out of the second rotating assembly 3.

In an embodiment, referring to fig. 5 to 8, the number of the actuating members 12 is plural, the plurality of actuating members 12 are arranged along the circumference of the first rotation center line 11, the number of the driven members 32 is plural, the plurality of driven members 32 are arranged along the circumference of the second rotation center line 31, and the actuating members 12 are in one-to-one correspondence with the driven members 32. In this way, the arrangement of the actuating element 12 and the arrangement of the follower 32 are simpler, and the difficulty in manufacturing the eccentric rotary device is reduced.
The term "plurality" means two or more and includes two. Illustratively, the number of actuating members may be 2, 5, 7, or 10, without limitation. Illustratively, the number of actuating members may be 2, 5, 7, or 10, without limitation.
It should be noted that, the actuating members 12 are in one-to-one correspondence with the driven members 32, and the number of actuating members 12 is equal to the number of driven members 32. For example, referring to fig. 8, the number of actuating members 12 and the number of driven members 32 are 7.
For example, referring to fig. 8, a plurality of actuating members 12 are disposed along the circumference of the first rotation center line 11, a plurality of driven members 32 are disposed along the circumference of the second rotation center line 31, two circles indicated by broken lines are shown, the circles indicated by broken lines coinciding with the centers of all actuating members 12 are first circles, and the centers of the first circles coincide with the first rotation center line 11.

In one embodiment, referring to fig. 8, the plurality of actuating members 12 are uniformly arranged along the circumference of the first rotation center line 11, and the plurality of driven members 32 are uniformly arranged along the circumference of the second rotation center line 31. In this way, the uniform arrangement simplifies the arrangement of the actuating element 12 and the driven element 32, and reduces the difficulty in manufacturing the eccentric rotary device. The uniform arrangement can ensure that at least one actuating piece 12 can drive the driven piece 32 to move as much as possible, and prevent the situation that the actuating piece 12 is difficult to drive the driven piece 32 to rotate around the second rotation center line because the direction of the acting force of all actuating pieces 12, which are abutted against the corresponding driven piece 32, is too close to the second rotation center line 31.
Among the plurality of actuating elements 12, the central angle of two adjacent actuating elements 12 is a first included angle with the first rotation center line 11 as the center. The plurality of actuating members 12 are uniformly arranged along the circumferential direction of the first rotation center line 11, which means that any two first included angles are equal, and the sum of all the first included angles is 360 °. Illustratively, the number of actuating members 12 is 7, the 7 actuating members 12 together form 7 first included angles with the first rotation centerline 11, each first included angle being 360 °/7, the sum of the 7 first included angles being 360 °.
Among the plurality of followers 32, the center angle of the adjacent two followers 32 is the second included angle with the second rotation center line 31 as the center. The plurality of followers 32 are uniformly arranged along the circumferential direction of the second rotation center line 31 means that any two second included angles are equal, and the sum of all the second included angles is 360 °. Illustratively, the number of followers 32 is 7, the 7 followers 32 forming 7 second angles with the second rotation centerline 31, each second angle being 360 °/7, the sum of the 7 second angles being 360 °.
In one embodiment, referring to fig. 8, the outer surface of the actuating member 12 can abut the outer surface of the driven member 32. In this way, the actuating member 12 and the driven member 32 are abutted through the corresponding outer surfaces, the actuating member 12 does not need to surround the driven member 32, the driven member 32 does not need to surround the actuating member 12, and the actuating member 12 and the driven member 32 can be made smaller, which is beneficial to reducing the cost. Furthermore, the actuating member 12 and the driven member 32 are abutted by the corresponding outer surfaces, and the actuating member 12 and the driven member 32 do not need to be connected by the connecting member 403, so that the structure can be simplified to a certain extent and the cost can be reduced.
In one embodiment, the outer surface of the actuating member 12 partially abuts the inner surface of the follower 32.
In one embodiment, the inner surface of the actuating member 12 abuts the outer surface of the follower 32.
In one embodiment, referring to FIG. 8, the shape of the actuating member 12 and the shape of the follower 32 are both cylindrical. In this way, the cylindrical actuating element 12 and the follower 32 are simple in construction and easy to produce.
For example, referring to fig. 7 and 8, the actuating members 12 are cylindrical in shape, and are projected along the first rotation center line 11, and a circle indicated by a broken line coinciding with the center of all the actuating members 12 is a first circle, and the center of the first circle coincides with the first rotation center line 11.

In one embodiment, referring to fig. 7 and 8, the distance between the first rotation center line 11 and the second rotation center line 31 is a predetermined distance. It should be noted that, the distance between the first rotation center line 11 and the second rotation center line 31 is a preset distance, that is, the first rotation center line 11 and the second rotation center line 31 are not coincident or intersect, and the preset distance is not 0.
In one embodiment, referring to fig. 10-12, the sum of the diameter of the actuating member 12 and the diameter of the follower 32 is less than or equal to twice the predetermined distance. In this way, the problem that the friction force between the actuating member 12 and the driven member 32 is large due to the large interference between the actuating member 12 and the driven member 32 is avoided, and abrasion between the actuating member 12 and the driven member 32 due to the large friction force is reduced.

For example, referring to fig. 10 to 12, the actuating member 12 and the driven member 32 are cylindrical, the preset distance is D1, the diameter of the actuating member 12 is D2, and the diameter of the driven member 32 is D3, d2+d3 is greater than or equal to 1.7d1.

Moreover, since the abrasion is small and the driven plate 34 is hardly subjected to the centrifugal load of the connecting member 403 in the related art, the material of the driven plate 34 can be properly reduced to select a material with a lower cost, which is advantageous for reducing the cost, while satisfying the strength requirement of the product.
