For example, at least two upper arms 21 are connected through a contraction member 303, when the edge brush device 20 rotates to a preset position, the first magnetic member 40 on the upper arm 21 approaches the second magnetic member 41, the second magnetic member 41 generates a repulsive force to the first magnetic member 40 toward one side of the rotating shaft 11, so that one upper arm 21 rotates toward one side of the rotating shaft 11 with the connection point of the connecting portion 23 and the mounting member 12 as a center, and drives the other upper arm 21 connected with the contraction member 303 to be stressed, and further drives the other lower arm 22 to rotate upward with the connection point of the connecting portion 23 and the mounting member 12 as a center, so that the cleaning member 24 is separated upward from the cleaning surface.

In order to mount the second magnetic member 41, in this embodiment, the lifting device further includes an auxiliary mounting member 42, the auxiliary mounting member 42 is sleeved on the rotating shaft 11, the rotating shaft 11 can rotate relative to the auxiliary mounting member 42, and the second magnetic member 41 is disposed on a peripheral wall of the auxiliary mounting member 42. When the edge brush device 20 rotates to a preset position, the first magnetic member 40 is close to the second magnetic member 41, and the second magnetic member 41 generates an attractive force towards one side of the rotating shaft 11 to the first magnetic member 40, so as to drive the upper arm 21 to rotate towards one side close to the rotating shaft 11 by taking the connecting point of the connecting part 23 and the mounting part 12 as a center, and further drive the lower arm 22 to rotate upwards by taking the connecting point of the connecting part 23 and the mounting part 12 as a center, so that the cleaning part 24 is separated from the cleaning surface upwards; when the edge brush device 20 is rotated out of the predetermined position, the first magnetic member 40 and the second magnetic member 41 are away from each other, the attraction force of the second magnetic member 41 to the first magnetic member 40 is gradually reduced, and the lower arm 22 is rotated downward to bring the cleaning member 24 into contact with the cleaning surface by the gravity of the edge brush device 20 itself.

It is understood that the utility model also provides another embodiment: the side brush devices 20 are arranged symmetrically in pairs, the rotating shaft 11 is located between the two symmetrical side brush devices 20, the contraction member 303 is sleeved on the side brush devices 20 which are symmetrical to each other, when one of the side brush devices 20 rotates to a preset position, the first magnetic member 40 on the upper arm 21 of one of the side brush devices 20 is close to the second magnetic member 41, the second magnetic member 41 generates a repulsive force to the first magnetic member 40, the repulsive force is opposite to one side of the rotating shaft 11, the contraction member 303 pulls the symmetrical side brush devices 20 under stress, the upper arms 21 of the symmetrical side brush devices 20 rotate towards one side of the rotating shaft 11 by taking a connection point of the connecting part 23 and the mounting part 12 as a center, and the cleaning member 24 is separated from the cleaning surface upwards.

It is understood that the present invention also provides another embodiment: at least two side brush devices 20 are arranged on the mounting part 12, the contraction part 303 is sleeved on at least two side brush devices 20, when one side brush device 20 rotates to a preset position, the first magnetic part 40 on the upper arm 21 of one side brush device 20 is close to the second magnetic part 41, the second magnetic part 41 generates a repulsive force to the first magnetic part 40, the repulsive force is opposite to one side of the rotating shaft 11, the contraction part 303 is forced to pull the other two side brush devices 20, the upper arms 21 of the other two side brush devices 20 rotate towards one side of the rotating shaft 11 by taking the connecting point of the connecting part 23 and the mounting part 12 as a center, and the cleaning part 24 is upwards separated from the cleaning surface.

Fig. 6 is a fifth embodiment of the edge brush assembly of the present invention.

The present embodiment differs from the fourth embodiment mainly in that:

the second magnetic member 41 is disposed in a different manner and the first magnetic member 40 and the second magnetic member 41 are engaged with each other.

In the present embodiment, the second magnetic member 41 is disposed above the side brush device 20, and the distance from the second magnetic member 41 to the rotating shaft 11 is greater than the distance from the first magnetic member 40 to the rotating shaft 11. When the edge brush device 20 rotates to the predetermined position, the first magnetic member 40 approaches the second magnetic member 41, and the second magnetic member 41 generates a downward repulsive force to the first magnetic member 40 toward one side of the rotating shaft 11, so as to drive the upper arm 21 to rotate toward one side close to the rotating shaft 11 with the connection point of the connecting portion 23 and the mounting member 12 as a center, and further drive the lower arm 22 to rotate upward with the connection point of the connecting portion 23 and the mounting member 12 as a center, so as to make the cleaning member 24 separate from the cleaning surface upward; when the edge brush device 20 is rotated out of the predetermined position, the first magnetic member 40 and the second magnetic member 41 are separated from each other, the repulsive force of the second magnetic member 41 to the first magnetic member 40 is gradually reduced, and the lower arm 22 is rotated downward by the gravity of the edge brush device 20 to bring the cleaning member 24 into contact with the cleaning surface.

In order to make the repulsive force of the second magnetic member 41 to the first magnetic member 40 larger when the first magnetic member 40 approaches the second magnetic member 41 to facilitate the upward rotation of the lower arm 22, the first magnetic member 40 and the second magnetic member 41 may be configured such that projected portions on a horizontal plane overlap when the first magnetic member 40 and the second magnetic member 41 approach each other, thereby facilitating the upward lifting of the cleaning member 24 more.

Fig. 7 is a sixth embodiment of an edge brush assembly of the present invention.

The present embodiment differs from the fourth embodiment mainly in that:

the second magnetic member 41 is disposed differently. In this embodiment, the second magnetic member 41 is disposed above the side brush device 20, and the distance from the second magnetic member 41 to the rotating shaft 11 is smaller than the distance from the first magnetic member 40 to the rotating shaft 11, when the side brush device 20 rotates to the preset position, the first magnetic member 40 is close to the second magnetic member 41, the second magnetic member 41 generates an attraction force towards one side of the rotating shaft 11 to the first magnetic member 40, so as to drive the upper arm 21 to rotate towards one side close to the rotating shaft 11 with the connection point of the connecting portion 23 and the mounting member 12 as the center, and further drive the lower arm 22 to rotate upwards with the connection point of the connecting portion 23 and the mounting member 12 as the center, so as to make the cleaning member 24 separate from the cleaning surface upwards; when the edge brush device 20 is rotated out of the predetermined position, the first magnetic member 40 and the second magnetic member 41 are away from each other, the attraction force of the second magnetic member 41 to the first magnetic member 40 is gradually reduced, and the lower arm 22 is rotated downward to bring the cleaning member 24 into contact with the cleaning surface by the gravity of the edge brush device 20 itself.

Alternatively, in the present embodiment, in order to make the attraction force of the second magnetic member 41 to the first magnetic member 40 larger when the first magnetic member 40 is close to the second magnetic member 41 to facilitate the upward rotation of the lower arm 22, the first magnetic member 40 and the second magnetic member 41 may be configured such that the projected portions of the first magnetic member 40 and the second magnetic member 41 on the vertical plane overlap, thereby facilitating the upward lifting of the cleaning member 24.

The stopper limits the position of the side brush device 20 when it is lowered, and prevents the side brush device 20 from being detached from the mounting member 12 when it is lowered.

In this embodiment, in order to make the first magnetic member 40 approach the second magnetic member 41, and make the attraction force of the second magnetic member 41 to the first magnetic member 40 greater so as to facilitate the lifting of the edge brush device 20, the first magnetic member 40 and the second magnetic member 41 may be configured such that the projections of the first magnetic member 40 and the second magnetic member 41 on the horizontal plane at least partially overlap, thereby facilitating the lifting of the cleaning member 24.

Of course, the arrangement and the matching relationship of the first magnetic member 40 and the second magnetic member 41 are not limited to the above embodiment, and any embodiment that utilizes the attraction or repulsion of the magnetic members to move the side brush device 20 relative to the mounting member 12 is within the scope of the present invention.
