In some embodiments, as shown in fig. 9, in the circumferential direction of the rolling brush body 11, the included angle between two adjacent first mating protrusions is α, in the circumferential direction of the sleeve 12, the included angle between two adjacent second mating protrusions is β, and satisfies: alpha is more than or equal to beta, namely the included angle of the two adjacent first matching protrusions in the circumferential direction is more than or equal to the included angle of the two adjacent second matching protrusions in the circumferential direction.
Thus, in the specific assembly, the tooth form angle of the rolling brush body 11 and the tooth form angle of the first driving member 23 are aligned to facilitate the assembly, for example, the first tooth groove 111 of the rolling brush body 11 and the first engaging protrusion of the first driving member 23 are aligned to be installed, wherein after the first tooth groove 111 and the first engaging protrusion are aligned, the rolling brush body 11 can be engaged with the first driving member 23 once per rotation angle α with respect to the first driving member 23, and the interval angle between two adjacent meshing times of the rolling brush body 11 and the first driving member 23 is α. Similarly, the tooth angle on the socket 12 can be aligned with the tooth angle on the second driving member 24 to facilitate the assembly of the two, for example, the second tooth groove 121 of the socket 12 can be installed to be aligned with the first mating protrusion of the second driving member 24, wherein after the second tooth groove 121 is aligned with the second mating protrusion, the socket 12 can be mated with the second driving member 24 once per rotation angle β relative to the second driving member 24, i.e., the interval angle between two adjacent meshes of the socket 12 and the second driving member 24 is β.

Alpha is larger than or equal to beta, so that the requirement on the alignment precision of the first driving part 23 assembled in advance and the rolling brush body 11 is low, and the rolling brush assembly 1 and the driving mechanism 2 are favorably and quickly positioned. Therefore, when the included angle between two adjacent first matching protrusions and the included angle between two adjacent second matching protrusions satisfy the angle relationship, the quick installation between the first driving part 23 and the rolling brush body 11 and between the second driving part 24 and the sleeve 12 can be ensured, no influence is generated between the first driving part and the sleeve, and when a user cannot install the floor brush assembly, the user can install the floor brush assembly again after retreating the first driving part 23 or the second driving part 24 and rotating for a certain angle, and the quick disassembly and installation of the floor brush assembly 100 are facilitated.
It should be noted that, in a specific installation process, after the rolling brush body 11 is engaged with the first driving member 23 and before the sleeve 12 is engaged with the second driving member 24, the bristles 112 are influenced by the width of the escape opening 122 of the sleeve 12, so that when the angle of the sleeve 12 is adjusted to accurately combine the sleeve 12 with the second driving member 24, the bristles 112 are ensured to protrude from the escape opening 122. Therefore, as shown in fig. 10, the maximum value of the rotational offset angle of the sleeve 12 held by the user can be γ, and γ is smaller than β, that is, the maximum value of the rotational offset angle of the sleeve 12 held by the user does not exceed the interval angle β between two adjacent engagements of the sleeve 12 and the second driving member 24, so that the rotational angle of the sleeve 12 can be prevented from exceeding the interval angle β after the rolling brush body 11 and the first driving member 23 are aligned and installed, thereby effectively preventing the sleeve 12 and the second driving member 24 from being assembled in a staggered manner, in other words, ensuring that the rolling brush body 11 and the sleeve 12 are not easily assembled in a staggered manner after the rolling brush body 11 is disassembled and installed back, and ensuring that the brush bristles 112 are aligned with the avoiding openings 122, so that the brush bristles 112 can effectively extend out.
