Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0057] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0058] Please refer to Figures 1 to 8The present invention provides a cleaning member, which includes a first cleaning body 1 and at least one second cleaning body 2. Specifically, Figure 2 As shown, the first cleaning body 1 includes a first housing 11, a first roller brush 12 and a driving assembly. The first roller brush 12 is rotatably mounted in the first housing 11, for example, the roller shaft of the first roller brush 12 is rotatably connected to the first housing 11 through a bearing assembly. The driving assembly is arranged in the first housing 11, and the driving end of the driving assembly is connected to the first roller brush 12, so that the first roller brush 12 can be driven to rotate around its own roller shaft, thereby achieving cleaning of the working surface.

[0059] The second cleaning body 2 includes a second shell 21 and a second roller brush 22. The second roller brush 22 is rotatably mounted in the second shell 21, for example, the roller of the second roller brush 22 is rotatably connected to the second shell 21 via a bearing assembly. The first cleaning body 1 and the second cleaning body 2 are detachably connected, so that the second cleaning body 2 can be installed or removed according to actual use requirements, and the operation is convenient. When the first cleaning body 1 and the second cleaning body 2 are connected, the roller of the first roller brush 12 is detachably fixedly connected to the roller of the second roller brush 22, so that the first roller brush 12 can drive the second roller brush 22 to rotate together, so that the cleaning area at the same time is increased, the working time is greatly shortened, and the work efficiency is improved.

[0060] Such a configuration enables rapid modification of the cleaning member according to different working conditions.

If the second cleaning body 2 is respectively provided at both ends of the first cleaning body 1, then Figure 3 and Figure 4 As shown, extension shafts 13 are respectively provided at both ends of the roller shaft of the first roller brush 12 .

[0065] Alternatively, the roller end of the second roller brush 22 may be provided with an extension shaft protruding from the second housing 21, and a corresponding shaft hole may be provided at the roller end of the first roller brush 12. If the second cleaning body 2 is provided at both ends of the first cleaning body 1, shaft holes are provided at both ends of the roller of the first roller brush 12.

[0066] In an optional embodiment of the utility model, the first connecting portion includes a first Velcro (not shown), and the second connecting portion includes a second Velcro (not shown). Thus, the first connecting portion and the second connecting portion are fixedly connected by the Velcro, which makes it easy to connect and separate the first roller brush 12 and the second roller brush 22, which is simple and quick.

[0067] In other embodiments of the present invention, a first magnet (not shown) is disposed at the roller end of the first roller brush 12, and a second magnet (not shown) is disposed at the roller end of the second roller brush 22, and the second magnet and the first magnet attract each other.

[0068] Alternatively, a third magnet is provided at the end of the roller shaft of one of the first roller brush 12 and the second roller brush 22, and an iron block is provided at the end of the other roller shaft.

Among them, the cleaning member also includes a limit member, and the limit member is arranged in the through hole 24 and the corresponding blind hole 14. For example, the limit member can be a bolt or a pin. When the first shell 11 is connected to the second shell 21, the through hole and the blind hole are aligned, and the limit member passes through the through hole and the blind hole in turn, thereby connecting the two side shells together. When it is necessary to separate the first shell 11 from the second shell 21, the limit member can be removed. It has a simple structure and is easy to operate.

[0071] As an optional embodiment of the utility model, one of the first shell 11 and the second shell 21 is provided with a flange, and the other shell is provided with a groove, and the flange and the groove are interference fit. That is to say, the first shell 11 is provided with a flange, and the second shell 21 is provided with a groove.
