The outermost water-soluble film layer 3 will gradually dissolve when encountering water. After dissolution, the melamine foam layer 2 loses the external pressure and gradually expands from the compressed state, increasing in volume, so as to fully fill the inside of the narrow gap; after the melamine foam layer 2 expands and fills the inside of the gap, only a simple sliding operation along the gap is required to adsorb the dirt inside the narrow gap on the melamine foam material with a porous structure, so as to achieve a comprehensive cleaning of the inside of the gap. It is convenient and fast to use, without repeatedly looking for angles to apply force, nor performing too many repeated cleaning operations, which can effectively improve the cleaning efficiency of the gap part, and the cleaning effect is obvious.

[0038] Further, in some embodiments of the present application, a surfactant 4 is filled in the melamine foam layer 2.

[0039] In the above embodiments, the melamine foam layer 2 has a porous structure.

[0044] Further, in some embodiments of the present application, the thickness of the above water-soluble film layer 3 is 0.03 - 0.10 mm.

[0045] In the above embodiments, by limiting the structural dimensions, it is ensured that the cleaning operation can be better performed on narrow gap parts.

[0046] Further, in some embodiments of the present application, a handle 5 for gripping is provided at the end of the above mounting support plate 1. One end of the above handle 5 is connected to the end of the above mounting support plate 1, and the other end is a free end.

[0047] Further, in some embodiments of the present application, the cross-section of the above handle 5 is L-shaped.

[0048] In the above embodiment, the handle with an L-shaped cross-section can facilitate the grasping of the cleaning brush while also making it more convenient to insert the cleaning brush body into narrow gaps such as corners and furniture crevices. Specifically, the short side of the L shape is connected to the mounting support plate 1, and the long side is for human hand grasping. Moreover, the short side of the L shape and the mounting support plate 1 are on the same horizontal plane, thereby ensuring that while the cleaning brush is stably grasped, the cleaning brush body can also be smoothly inserted into the narrow gap where cleaning work needs to be carried out, which is more conducive to use.

[0049] Furthermore, in some embodiments of the present application, the overall cross-section of the above brush body is elliptical, and the mounting support plate 1 is arranged along the long axis direction of the ellipse.

[0050] In the above embodiment, the brush body with an elliptical cross-section can more conveniently penetrate into narrow gap parts for cleaning work; and the mounting support plate 1 arranged along the long axis of the ellipse, in cooperation with the handle with an L-shaped cross-section, can also make the grasping and cleaning operations more convenient.
