The driving structure can comprise an output shaft of the motor, the matching part can be a matching column with a shaft hole, the output shaft extends out of the matching column through the shaft hole and is in transmission connection with the brush body 21 sleeved on the matching column, and a rotating gear meshed with the output shaft is arranged in the brush body 21. Of course, the specific structure of the mating part is not limited to the above example, and the specific implementation manner of the driving structure driving the brush body 21 to rotate is not limited to the above example, and is not limited in this application. It should be noted that, the brush body 21 can be self-rotatably sleeved on the mating portion, and includes that the mating portion does not move the rotation of the brush body 21 and the mating portion communicates with the rotation of the brush body 21, and there are various implementation manners, and the above example can implement that the mating portion does not move and the rotation of the brush body 21 is synchronized, and the manner of implementing that the mating portion communicates with the rotation of the brush body 21 is that the mating portion includes an installation shaft and a transmission gear installed on the installation shaft, the transmission gear is in transmission connection with the driving structure and rotates under the driving of the driving structure, and the brush body 21 is sleeved on the transmission gear and implements its rotation when the transmission gear rotates.

In some embodiments, one of the fitting 22 and the fitting part b is configured with an elastic part 23, and the other is configured with a concave part f, when the fitting 22 is switched to the first state, the elastic part 23 is deformed to the concave part f under the control of self-restoring force, and when the fitting 22 is switched to the second state, the elastic part 23 is pressed and deformed to be separated from the concave part f.

When the assembly member 22 is in the first state, the assembly member 22 and the assembly portion b are in clamping fit with the concave portion f through the elastic portion 23. When the rolling brush 20 needs to be disassembled, a user provides an external force to enable the brush body 21 to rotate towards the direction of disengaging from the rolling brush cavity a by taking the mating part as a center, and the assembly part 22 and the brush body 21 synchronously move towards the direction of disengaging from the rolling brush cavity a, in the process, the elastic part 23 is pressed and deformed to disengage from the concave part f until the assembly part b is separated from the assembly part 22 and cannot prevent the rolling brush 20 from disengaging from the rolling brush cavity a, at the moment, the assembly part 22 is in the second state, and the elastic part 23 is restored to the initial state.

It should be noted that, when the fitting 22 is switched to the first state, the elastic portion 23 is deformed to the click-fit recessed portion f under the control of its own restoring force, but other deformation processes of the elastic portion 23 may be present, and for example, when the elastic portion is deformed to the click-fit recessed portion f, a pressure applied by the fitting portion b or the fitting 22 may be present. When the fitting 22 is switched to the second state, there is a deformation of the elastic portion 23 to escape from the recessed portion f by the pressure provided by the fitting portion b or the fitting 22, but there may be other deformation processes of the elastic portion 23, such as returning to the initial state under the control of its own restoring force when the brush body 21 is rotated by a certain angle until the elastic portion 23 is completely separated from the fitting portion b where the recessed portion f is located or the fitting 22.

At this time, the connection reliability of the fitting part b and the fitting 22 can be enhanced by the elastic part 23 and the concave part f, and the rotational stability of the roll brush can be improved.

In particular, in the embodiment, the elastic portion 23 is configured to have a deformation component in the axial direction of the brush body 21 when deformed and compressively deformed under the control of its own restoring force.

The spring piece 24 is provided to the mounting member 22, and the recessed portion f is provided to the mounting portion b. When the rolling brush 20 is installed, the brush body 21 is firstly sleeved on the matching part, then the brush body 21 is rotated to enable the assembling part 22 to gradually approach the assembling part b, in the process, the free end 24b of the elastic sheet 24 is gradually pressed by the assembling part b from a free state until the pressure borne by the free end 24b is smaller than the restoring force when meeting the concave part f, and the convex part 24c is clamped in the concave part f when rebounding under the control of the restoring force. When the rolling brush 20 is disassembled, external force is applied to rotate the brush body 21 around the matching part, the free end 24b of the elastic sheet 24 is gradually pressed by the pressure of the edge of the concave part f and is separated from the concave part f, and the assembly part 22 is conveniently separated from the assembly part b.

Understandably, the fixed end 24a of the spring piece 24 is located at the side of the free end 24b in the first rotation direction, which defines that the rolling brush 20 is separated from the rolling brush cavity a when rotating in the first rotation direction around the matching part, so that the free end 24b is pressed and separated from the concave part f when the rolling brush 20 is rotated out.

Of course, in other embodiments, the elastic portion 23 may be a spring, so long as it can be tightly engaged with the concave portion f by its own restoring force when the assembly 22 is in the first state, and can be deformed to be disengaged from the concave portion f when the assembly 22 is switched to the second state.
