These terms are only used to distinguish different structures. For example, without departing from the scope of the embodiments of the present disclosure, the second component can also be referred to as the second component, and similarly, the second component can also be referred to as the second component.

[0044] Depending on the context, the word "if" as used herein can be interpreted to mean "when" or "upon" or "in response to determining" or "in response to detecting". Similarly, depending on the context, the phrase "if it is determined" or "if (a stated condition or event) is detected" can be interpreted to mean "when it is determined" or "in response to determining" or "when (a stated condition or event) is detected" or "in response to detecting (a stated condition or event)".

[0045] It should also be noted that the terms "comprising", "including", or any other variant thereof are intended to cover non-exclusive inclusion, so that a product or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such product or device. Without more limitations, the element defined by the sentence "including a" does not exclude the presence of additional identical elements in the product or device including the element.

[0046] FIG. 1 shows a schematic diagram of a rolling brush 100' in the related art. As shown in FIG. 1, in the related art, the rolling brush 100' of the cleaning module is usually a column body, and cleaning blades are arranged on the rotating shaft or rotating drum. During the execution of the cleaning task, the self-moving cleaning device 900 gradually gathers the hair or other garbage on the ground to one side or both sides. If the hair on the ground adheres to the blades of the rolling brush 100', it will affect the dust collection effect of the cleaning robot and the rolling brush 100' needs to be cleaned frequently, which causes trouble to the user.

[0047] In order to solve at least one of the above technical problems, the present disclosure provides a rolling brush 100, a cleaning module and a self-moving cleaning device. The rolling brush 100 for a self-moving cleaning device can include: a first rolling brush body 110, which can include a first driving part 111 and a first working part 112; the first driving part 111 and the first working part 112 are respectively arranged at both ends of the first rolling brush body 110; the first driving part 111 is configured to be connected with a driving assembly; a second rolling brush body 120, which can include a second driving part 121 and a second working part 122; the second driving part 121 and the second working part 122 are respectively arranged at both ends of the second rolling brush body 120; the second driving part 121 is configured to be connected with a driving assembly; wherein the minimum distance between the first working part 112 and the second working part 122 changes constantly when the first rolling brush body 110 and / or the second rolling brush body 120 rotates. The rolling brush 100 of the present disclosure uses the minimum distance between the first working part 112 and the second working part 122 constantly changing during the rotation of the first rolling brush body 110 and the second rolling brush body 120, so as to squeeze the garbage gathered between the first rolling brush body 110 and the second rolling brush body 120 by the first working part 112 and the second working part 122; when the minimum distance between the first working part 112 and the second working part 122 becomes larger, the garbage squeezed and rubbed into a ball is loosened, and then is sucked into the dust box by the fan, thereby preventing the hair from winding around the blades of the rolling brush and affecting the dust collection effect.

[0048] The optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0049] FIG. 2 shows a structural schematic diagram of the rolling brush 100 according to an embodiment of the present disclosure. FIG. 3 shows a structural schematic diagram of the rolling brush 100 according to another embodiment of the present disclosure. As shown in FIGS. 2 and 3, according to the specific implementation of the present disclosure, a rolling brush 100 is provided for a self-walking cleaning device, which can include: a first rolling brush body 110, which can include: a first driving part 111 and a first working part 112; the first driving part 111 and the first working part 112 are respectively arranged at two ends of the first rolling brush body 110; the first driving part 111 is configured to be connected with a driving assembly, and the first working part 112 is provided with a first working part 112 at one end away from the first driving part 111; the first rolling brush body 110 can be a roller, and the roller is provided with first cleaning blades 114, which are inclined along the axial direction of the first rolling brush body 110; the first rolling brush body 110 can be a roller shaft, and the roller shaft is provided with first cleaning blades 114, which are inclined along the axial direction of the first rolling brush body 110. A second rolling brush body 120, which can include: a second driving part 121 and a second working part 122; the second driving part 121 and the second working part 122 are respectively arranged at two ends of the second rolling brush body 120; the second driving part 121 is configured to be connected with a driving assembly, and the second working part 122 is provided with a second working part 122 at one end away from the second driving part 121; the second rolling brush body 120 can be a roller, and the roller is provided with second cleaning blades 124, which are inclined along the axial direction of the second rolling brush body 120; the second rolling brush body 120 can be a roller shaft, and the roller shaft is provided with second cleaning blades 124, which are inclined along the axial direction of the second rolling brush body 120. Wherein, when the first rolling brush body 110 and / or the second rolling brush body 120 rotates, the minimum distance between the first working part 112 and the second working part 122 constantly changes. The rolling brush 100 of the present disclosure is divided into the first rolling brush body 110 and the second rolling brush body 120, and the minimum distance between the first working part 112 and the second working part 122 changes during the cleaning process; when the first working part 112 and the second working part 122 gradually contact, the garbage gathered between the first rolling brush body 110 and the second rolling brush body 120 is kneaded; when the first working part 112 and the second working part 122 gradually separate, the kneaded garbage is released and then sucked into a dust box, realizing the self-cleaning function of the rolling brush 100.

[0050] It should be noted that the first driving part 111 and the second driving part 121 can be connected to the same driving assembly, or can be driven by different driving assemblies, so that the rotating speeds of the first rolling brush body 110 and the second rolling brush body 120 have a speed difference, and the minimum distance between the first working part 112 and the second working part 122 changes constantly, so that the garbage gathered between the first rolling brush body 110 and the second rolling brush body 120 is rubbed by the extrusion between the first working part 112 and the second working part 122; when the minimum distance between the first working part 112 and the second working part 122 becomes larger, the garbage squeezed and rubbed into a ball is loosened and then sucked into the dust box by the fan.

[0051] Fig. 4 shows a structural schematic diagram of the first rolling brush body 110 and the second rolling brush body 120 in a first state according to an embodiment of the present disclosure. Fig. 5 shows a structural schematic diagram of the first rolling brush body 110 and the second rolling brush body 120 in a second state according to an embodiment of the present disclosure. As shown in Fig. 4 and Fig. 5, in some embodiments, when the first rolling brush body 110 and / or the second rolling brush body 120 rotates, specifically, in an embodiment of the present disclosure, the rotation of the first rolling brush body 110 and / or the second rolling brush body 120 can include: the rotation of the first rolling brush body 110 and the rotation of the second rolling brush body 120, in the process, there is a speed difference between the rotation speed of the first rolling brush body 110 and the rotation speed of the second rolling brush body 120, so as to realize the continuous change of the minimum distance between the first working part 112 and the second working part 122; in another embodiment of the present disclosure, the rotation of the first rolling brush body 110 and the non-rotation of the second rolling brush body 120, in the process, the continuous change of the minimum distance between the first working part 112 and the second working part 122 can also be realized; in still another embodiment of the present disclosure, the non-rotation of the first rolling brush body 110 and the rotation of the second rolling brush body 120, in the process, the continuous change of the minimum distance between the first working part 112 and the second working part 122 can also be realized; optionally, the rotation of the first rolling brush body 110 and the rotation of the second rolling brush body 120 with a speed difference. The continuous change of the minimum distance between the first working part 112 and the second working part 122 can include: the change from the first state to the second state and then the change from the second state to the first state between the first working part 112 and the second working part 122, wherein the first state is the state that the minimum distance between the first working part 112 and the second working part 122 is the minimum value, and the second state is the state that the minimum distance between the first working part 112 and the second working part 122 is the maximum value. As shown in Fig. 4, with the rotation of the first rolling brush body 110 and the second rolling brush body 120, the state between the first working part 112 and the second working part 122 presents a cycle state of "the first state-the second state-the first state". When the first working part 112 and the second working part 122 are in the first state, the first working part 112 and the second working part 122 are in a squeezed state, and the garbage between the first working part 112 and the second working part 122 is rubbed into a ball; as shown in Fig. 5, when the first working part 112 and the second working part 122 are in the second state, the first working part 112 and the second working part 122 are in an open state, and the garbage between the first working part 112 and the second working part 122 is loosened.

[0052] In some embodiments, the first working part 112 is made of elastic material. In an alternative embodiment, the second working part 122 is made of elastic material. Alternatively, the first working part 112 is made of elastic material and the second working part 122 is made of steel material. In this case, the first working part 112 and the second working part 122 generate greater force on the kneading of garbage, the kneading of garbage is more thorough, and the compression amount is also greater, but the scroll brush 100 receives greater axial force. Alternatively, the first working part 112 is made of rigid material and the second working part 122 is made of elastic material. In this case, the first working part 112 and the second working part 122 generate greater force on the kneading of garbage, the kneading of garbage is more thorough, and the compression amount is also greater, but the scroll brush 100 receives greater axial force. Alternatively, the first working part 112 is made of elastic material and the second working part 122 is also made of elastic material. In this case, the first working part 112 and the second working part 122 generate a certain force on the kneading of garbage, the kneading of garbage has a certain compression amount, but the scroll brush 100 receives smaller axial force, which can protect the scroll brush 100 and prevent the scroll brush 100 from being frequently compressed by rigid material to shorten the service life. When the first working part 112 and the second working part 122 are in the first state, the first working part 112 and the second working part 122 are pressed against each other, and the first working part 112 and the second working part 122 are compressed. Specifically, in some embodiments, the Rockwell hardness of the first working part 112 is 60-100 mm. Alternatively, the Rockwell hardness of the first working part 112 is 60, 70, 80, 90, or 100 mm. In an alternative embodiment, the Rockwell hardness of the second working part 122 is 60-100 mm. Alternatively, the Rockwell hardness of the second working part 122 is 60, 70, 80, 90, or 100 mm. Alternatively, the Rockwell hardness of the first working part 112 is 80 mm. When the Rockwell hardness of the first working part 112 is 80 mm, it has a hardness that can knead garbage into a ball and can be compressed by the extrusion force. Alternatively, the Rockwell hardness of the second working part 122 is 80 mm. When the Rockwell hardness of the second working part 122 is 80 mm, it has a hardness that can knead garbage into a ball and can be compressed by the extrusion force.In some embodiments, the minimum distance between the first working part 112 and the second working part 122 is -0.2-1.0 mm; specifically, when the minimum distance is negative, it means that at least one of the first working part 112 and the second working part 122 is compressed at the first state; when the minimum distance is 0 mm, it means that the first working part 112 and the second working part 122 are in contact but do not generate force at the first state without garbage; when the minimum distance is 0-1.0 mm, it means that the distance between the first working part 112 and the second working part 122 is at the first state. When the first working part 112 and the second working part 122 are at the first state, at least one of the first working part 112 and the second working part 122 is compressed; when the first working part 112 and the second working part 122 are at the second state, at least one of the first working part 112 and the second working part 122 is compressed. When the Rockwell hardness of the first working part 112 is 60-100 mm, it has a hardness that can rub the garbage into a ball, and can also be compressed by extrusion force, and the compression degree is 0-0.1 mm; when the Rockwell hardness of the second working part 122 is 60-100 mm, it has a hardness that can rub the garbage into a ball, and can also be compressed by extrusion force, and the compression degree is 0-0.1 mm.

[0053] In some embodiments, when the first roller brush body 110 and the second roller brush body 120 rotate, the first roller brush body 110 and the second roller brush body 120 rotate in the same direction, and there is a speed difference between the rotation of the first roller brush body 110 and the second roller brush body 120. In an optional embodiment, the speed difference is 3-25%. The first working part 112 of the present disclosure is in an eccentric state towards the second working part 122, and the second working part 122 is also in an eccentric state towards the first working part 112; through the differential rotation of the first roller brush body 110 and the second roller brush body 120, the cycle state of "the first state-the second state-the first state" is completed. Through the structure of the roller brush 100 of the present application, the garbage can be squeezed and rubbed and released; too fast speed will cause incomplete rubbing, and too slow speed will cause too much accumulation of garbage; the speed difference of 3-25% can prevent the garbage from not forming a ball and prevent the garbage from falling out due to too much. Optionally, the speed difference is 5%, 10%, 15%, etc. Optionally, the speed difference is 14%, at which the garbage squeezed is good in ball formation and is not easy to fall out, and after being formed into a ball, it is sucked into the dust box.

[0054] In some embodiments, the first rolling brush body 110 is tapered, with a larger cross section closer to the first driving portion 111 and a smaller cross section farther from the first driving portion 111. In an alternative embodiment, the second rolling brush body 120 is tapered, with a larger cross section closer to the second driving portion 121 and a smaller cross section farther from the second driving portion 121. The first rolling brush body 110 and the second rolling brush body 120 are designed to be tapered, so that the first rolling brush body 110 and the second rolling brush body 120 form an inclined surface. During the cleaning process, garbage moves to the middle (between the first rolling brush body 110 and the second rolling brush body 120) due to gravity, and is then pressed and rubbed into a ball. In an alternative embodiment, when the self-walking cleaning device is placed on a cleaning surface, the generatrix of the first rolling brush body 110 closest to the cleaning surface is substantially parallel to the cleaning surface. At this time, the bottom end of the first rolling brush body 110 is parallel to the cleaning surface being cleaned. Alternatively, the generatrix of the second rolling brush body 120 closest to the cleaning surface is substantially parallel to the cleaning surface. The generatrix of the first rolling brush body 110 and the second rolling brush body 120 closest to the cleaning surface is substantially parallel to the cleaning surface, so that the cleaning surface of the rolling brush 100 is parallel to the cleaning surface being cleaned during the cleaning process of the self-moving cleaning device, preventing missed cleaning.

[0055] In some embodiments, the first working part 112 has a first face 1121 at one end away from the first driving part 111, and the second working part 122 has a second face 1221 at one end away from the second driving part 121; the first face 1121 is a plane and the plane is not perpendicular to the axial direction of the first rolling brush body 110. In an alternative embodiment, the second face 1221 is a plane and the plane is not perpendicular to the axial direction of the second rolling brush body 120. In other embodiments, the first working part 112 has a first face 1121 at one end away from the first driving part 111, and the second working part 122 has a second face 1221 at one end away from the second driving part 121; the first face 1121 is a curved surface and the center of the curved surface is not in the axial direction of the first rolling brush body 110. In an alternative embodiment, the second face 1221 is a curved surface and the center of the curved surface is not in the axial direction of the second rolling brush body 120. In yet other embodiments, the first working part 112 has a first face 1121 at one end away from the first driving part 111, and the second working part 122 has a second face 1221 at one end away from the second driving part 121; the first face 1121 is a spherical surface and the center of the spherical surface is not in the axial direction of the first rolling brush body 110. In an alternative embodiment, the second face 1221 is a spherical surface and the center of the spherical surface is not in the axial direction of the second rolling brush body 120. The first face 1121 and the second face 1221 can be a plane, a curved surface or a spherical surface, but all need to be eccentric structures, i.e. one part of the first face 1121 is close to the second face 1221 and the other part is far away from the second face 1221 (one part of the second face 1221 is close to the first face 1121 and the other part is far away from the first face 1121). Through the eccentric structure combined with differential rotation, the cycle state of "the first state-the second state-the first state" is completed. Alternatively, the first face 1121 and the second face 1221 are both spherical surfaces, which are easy to form hair balls and have good hair ball forming effect.

[0056] In some embodiments, the first rolling brush body 110 is provided with first bristles 113 which are inclined along the axial direction of the first rolling brush body 110. In an alternative embodiment, the second rolling brush body 120 is provided with second bristles 123 which are inclined along the axial direction of the second rolling brush body 120.
