[0021] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, and to make the above-mentioned purposes, features and advantages of the embodiments of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be further described in detail below with reference to the drawings. The features in the following embodiments and implementation manners can be combined with each other without conflict.

[0022] Referring to Figures 1 to 3 The present application provides a cleaning device, comprising a device body 10 and a rolling brush structure 20, wherein the rolling brush structure 20 is arranged on the device body 10, and the rolling brush structure 20 can be arranged on the device body 10 in a detachable manner, so as to facilitate disassembly, replacement and cleaning of the rolling brush. Optionally, the rolling brush structure 20 is arranged at the bottom of the device body 10, as shown in Figure 2 The cleaning device can comprise a sweeping machine, a washing machine, a vacuum cleaner or a mite removal device, etc. Figure 1Taking the cleaning device as a floor cleaning machine as an example, the cleaning device can further include a charging base 30 for charging the device body 10, and the device body 10 can be further provided with a clean water tank and a sewage tank, etc. When the cleaning device is a vacuum cleaner, a handheld piece and a hard tube can also be included.

[0023] As shown in Figure 3 , the rolling brush structure 20 includes a housing 21 and two rolling brushes 22. The two rolling brushes 22 are arranged side by side along the rotation axis X in the housing 21, and both of the two rolling brushes 22 can rotate around the rotation axis X relative to the housing 21.

[0024] As shown in Figure 3 , in some optional embodiments, in a projection plane parallel to the rotation axis X, the two rolling brushes 22 at least partially overlap along the end adjacent to the rotation axis X. As shown in A in Figure 4 , the two rolling brushes 22 can overlap in the projection in the direction perpendicular to the rotation axis X to cover the cleaning area, so that the cleaning range is larger and the cleaning effect is better.

[0025] In the embodiment, the rolling brushes 22 are arranged along the rotation axis X, and the end faces of the two rolling brushes 22 at the end adjacent to the rotation axis X are both inclined relative to the rotation axis X and parallel to each other. In this way, the two rolling brushes 22 can form partial overlap in the projection plane parallel to the rotation axis X. In other embodiments, the two rolling brushes 22 can also be arranged in staggered L-shaped and inverted L-shaped forms, and also can form partial overlap in the projection plane parallel to the rotation axis X. Alternatively, the included angle between the end face of the two rolling brushes 22 at the end adjacent to the rotation axis X and the rotation axis X ranges from 30° to 60°, which can be adjusted according to actual needs.

[0026] In the case that the two rolling brushes 22 form partial overlap in the projection plane parallel to the rotation axis X, the two rolling brushes 22 rotate around the rotation axis X at the same frequency and in the same direction relative to the housing 21, so as to avoid mutual collision of the overlapping parts during rotation.

[0027] In some optional embodiments, the spacing between the two rolling brushes 22 at the end adjacent to the rotation axis X ranges from 2mm to 6mm. The spacing can refer to the spacing between the two parallel end faces of the two rolling brushes 22 at the end adjacent to the rotation axis X. The specific value of the spacing can be set according to user needs.

[0028] As shown in Figure 4As shown, in some optional embodiments, the rolling brush structure can further include a bracket assembly 40 arranged in the housing 21, and a driving member 42 arranged in the bracket assembly 40, and the rolling brush 22 is connected with the driving member 42. The driving member 42 is used to drive the rolling brush 22 to rotate around the rotation axis X. Optionally, the bracket assembly 40 can include a bracket 402, the driving member 42 can include a motor arranged in the bracket 402, and the rolling brush 22 can be connected with the driving member 42 through an intermediate transmission member (not shown) arranged in the bracket 402. Alternatively, the rolling brush 22 can be directly connected with the driving member 42.

[0029] In some optional embodiments, the housing 21 is provided with a dust collecting opening 211, and the two rolling brushes 22 are arranged corresponding to the dust collecting opening 211. It can be understood that the device main body 10 can be provided with a dust collecting cavity in communication with the dust collecting opening 211, so that it is more convenient for the rolling brush 22 to send the cleaned garbage into the dust collecting cavity through the dust collecting opening 211 for collection.

[0030] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
