DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] Before the embodiments of the present application are described in further detail, the orientation terms such as “upper”, “lower”, “side” in the embodiments of the present application do not have the meaning of limiting the scope of protection of the present application.

[0043] In order to make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the drawings.

[0044] Fig. 1 is a schematic view of a rolling brush module according to an embodiment of the present application;

[0045] As shown in Figs. 1 and 2, one embodiment of the present application provides a rolling brush module 100, which comprises:

[0046] a roller body 110, through which dirt on a surface to be cleaned is removed by rotation of the roller body 110, one end of the roller body 110 being provided with a support 170, the support 170 being connected to the roller body 110 through a connecting shaft 171, the roller body 110 rotating relative to the support;

[0047] an air making part, which is arranged to form at least part of an air volume between the support 170 and the roller body 110.

[0048] The roll brush module 100 includes a roller body 110, and dirt on the surface to be cleaned can be removed by rotation of the roller body 110. The support 170 is generally fixed, and the roller body 110 is connected to the support 170 through a connecting shaft 171. When the roller body 110 rotates, the support 170 is fixed and does not rotate. At this time, the strip-shaped garbage such as hair will be wound around the connecting shaft 171 between the support 170 and the roller body 110. The air volume is formed between the support 170 and the roller body 110 by the air making part, which can blow the strip-shaped garbage away from the position of the connecting shaft 171 between the support 170 and the roller body 110, thereby avoiding the strip-shaped garbage from being brought into the connecting shaft 171 when the roller body 110 rotates, and affecting the rotation of the roller body 110. That is, the air making part can gather air energy at the support 170, and the strip-shaped garbage can be blown away from the support 170 by the air energy, thereby avoiding the strip-shaped garbage from being wound around the connecting shaft 171 of the support 170, affecting the rotation of the roller body 110, ensuring the working reliability and stability of the roll brush module 100, and prolonging the service life of the roll brush module 100.

[0049] Specifically, the support 170 is connected to the roller body 110 through the connecting shaft 171 and the bearing. The rotation of the roller body 110 can bring the strip-shaped garbage to the connecting shaft 171, causing the strip-shaped garbage to be wound around the connecting shaft 171. The air making part is arranged to form at least part of the air volume between the support 170 and the roller body 110. That is, the air making part forms an air flow around the support 170, and the strip-shaped garbage such as hair and broken wires gathered around the support 170 is blown away from the support 170 by the air flow, so as to avoid the strip-shaped garbage from being wound around the connecting shaft 171 of the support 170 and being unable to be cut, thereby affecting the rotation of the roller body 110. That is, when the strip-shaped garbage cannot be wound around the connecting shaft 171 of the support 170 or only a small amount of strip-shaped garbage is wound around the connecting shaft 171 of the support 170, the working reliability and stability of the roll brush module 100 can be ensured. It can be understood that the small amount refers to 1 to 5 strip-shaped garbage, or the amount of strip-shaped garbage that does not affect the normal rotation of the roller body 110.

[0050] FIG. 2 is a schematic view of the air supply part according to one embodiment of the present application; and FIG. 3 is a schematic view of the air supply part according to another embodiment of the present application.

[0051] In a possible implementation, as shown in FIGS. 2 and 3, the air supply part includes a first air making part 150 and / or a second air making part 160; wherein,

[0052] The first air making part 150 introduces at least part of the external air volume to between the support 170 and the roller body 110 through a first pipeline;

[0053] The second air making part 160 includes a wind forming structure, and the wind forming structure rotates to form the air volume.

[0054] Wherein, the air making part can only include the first air making part 150, or only include the second air making part 160, or include both the first air making part 150 and the second air making part 160.

[0055] Specifically, when the air making part only includes the first air making part 150, the first air making part 150 includes a first pipe (not shown), one end of the first pipe is connected with any space capable of forming air flow, and the other end of the first pipe is led to the connecting shaft 171 between the bracket 170 and the roller body 110, i.e. the position between the roller body 110 and the bracket 170. By leading the air flow of other spaces to the connecting shaft 171 between the bracket 170 and the roller body 110, the strip-shaped garbage near the connecting shaft 171 of the bracket 170 can be blown away. This space capable of forming air flow can be a separate fan, so that the fan forms air flow in a space, or a dust suction fan of the automatic cleaning device 200 where the roller brush module 100 is located. When a separate fan is provided, since part of the air flow of the dust suction fan does not need to be introduced, the air flow of the dust suction fan of the automatic cleaning device 200 can be ensured not to be affected. When the dust suction fan is used, the size of the main machine of the automatic cleaning device 200 does not need to be changed, and the volume and weight of the automatic cleaning device 200 can be ensured unchanged. It can be selected according to actual needs. When the air making part only includes the second air making part 160, the second air making part 160 includes a wind forming structure, and the wind forming structure is rotated by a power structure, so that the second air making part 160 forms a rotating air flow near the bracket 170, or the air flow of the wind forming structure is introduced to the bracket 170, thereby preventing the strip-shaped garbage from winding around the connecting shaft 171 of the bracket 170.

[0056] It can be understood that the first air making part 160 and the second air making part 160 can be provided in the roller brush module 100 at the same time, so that sufficient air flow can be sent to the connecting shaft 171 of the bracket 170, and the purpose of preventing the strip-shaped garbage from winding around the bracket 170 is further achieved.

[0057] In a feasible implementation, one end of the roller body 110 is provided with a baffle 120, the baffle 120 is located between the roller body 110 and the bracket 170, and the first air making part 150 and / or the second air making part 160 forms at least part of the air flow between the bracket 170 and the baffle 120.

[0058] It should be noted that one end of the roller body 110 is provided with a baffle 120, the baffle 120 is located between the roller body 110 and the support 170, and the baffle 120 is integrally formed with the roller body 110, welded or detachably connected. Generally, the first pipe of the first air making part 150 passes through the brush roller shell and the support 170, and at least part of the air volume is introduced between the support 170 and the baffle 120, so that the air volume is formed between the support 170 and the baffle 120. The second air making part 160 directly forms the air volume between the support 170 and the baffle 120 through the rotation of the air forming structure, or the second air making part 160 forms the air volume through the rotation of the air forming structure and introduces the air volume to the position between the support 170 and the baffle 120.

[0059] It can be understood that one end of the roller body 110 is connected with the support 170, and the other end of the roller body 110 is suspended, that is, the support of the roller body 110 is realized by one support 170, so that the air making part is arranged at the end of the roller body 110 connected with the support 170. That is, in the length direction of the roller body 110, as shown in FIG. 1, the right side of the roller body 110 is the first end of the roller body 110, the left side of the roller body 110 is the second end of the roller body 110, and the first end of the roller body 110 is provided with the first air making part 150 and / or the second air making part 160. That is, only the first air making part 150 is arranged at the first end of the roller body 110, or only the second air making part 160 is arranged at the first end of the roller body 110, or the first air making part 150 and the second air making part 160 are arranged at the first end of the roller body 110.

[0060] In a feasible embodiment, the first air making part 150 includes at least one air supply channel 151 arranged on the roller body 110, and the air supply channel 151 penetrates the baffle 120, one end of the first pipe is connected with the air outlet of the fan, and the other end of the first pipe is located in the air supply channel 151; and / or the center of the roller body 110 is provided with a center channel, the air supply channel is communicated with the center channel, one end of the first pipe is connected with the air outlet of the fan, and the other end of the first pipe is arranged in the air supply channel 151 after the first pipe passes through the air supply channel.

[0061] At least one air supply channel 151 is arranged on the outer periphery of the roller body 110, and the air supply channel 151 penetrates the side wall of the roller body 110 and the baffle 120, so that the first pipe can guide the air of the fan to the space between the support 170 and the baffle 120, thereby forming an air flow between the support 170 and the baffle 120, and avoiding that the strip-shaped garbage is wound on the connecting shaft 171 of the support 170. When the first air making part 150 includes a plurality of air supply channels 151, the plurality of air supply channels 151 can be uniformly arranged on the outer periphery of the roller body 110, or only a plurality of air supply channels 151 can be arranged on part of the outer periphery of the roller body 110, as long as the air flow can be formed between the support 170 and the baffle 120. The distance between the adjacent two air supply channels 151 and the inclination angle are not limited.

[0062] It can be understood that when there are a plurality of air supply channels 151, one end of the first pipe is in communication with the space where the fan is located, and the other end of the first pipe is provided with a plurality of air outlets, and the plurality of air outlets are respectively in communication with the plurality of air supply channels 151, so that the first pipe can be prevented from being wound when the roller body 110 rotates, the ventilation function of the first pipe is ensured, and the reliability of the first air making part 150 is ensured.

[0063] It should be noted that the air supply channel 151 on the outer periphery of the roller body 110 can be a groove-shaped channel, and the first pipe is installed in the groove-shaped channel, and the other end of the first pipe penetrates the baffle 120, so that the air volume can be guided to the space between the support 170 and the baffle 120, and at this time the groove-shaped channel is a containing groove of the first pipe; or the air supply channel 151 on the outer periphery of the roller body 110 can be a closed channel, that is, a first port is arranged on the outer periphery of the roller body 110, a second port is arranged on the baffle 120, the first port and the second port are in communication to form a closed air supply channel 151, and the first pipe is arranged in the closed air supply channel 151, so that the length of the first pipe can be effectively shortened, that is, the first pipe can be fixed in the first port, and the air volume can be guided to the space between the support 170 and the baffle 120 through the closed channel.

[0064] In order to realize the connection between the roller body 110 and the connecting shaft 171 of the support 170, a center channel is arranged at the axial center of the roller body 110, and at least part of the connecting shaft 171 is located in the center channel, so that the air supply channel 151 can penetrate the side wall of the roller body 110, so that the air supply channel 151 is in communication with the center channel, one end of the first pipe is connected with the space where the air outlet of the fan is located, and the other end of the first pipe is arranged in the air supply channel 151. Since the center channel is a blind hole, and the connecting shaft 171 of the support 170 is not completely sealed, the air volume of the fan can be guided to the position between the support 170 and the baffle 120 through the air supply channel 151 and the center channel, so that the strip-shaped garbage is prevented from being wound on the connecting shaft 171 of the support 170.

[0065] In an embodiment, the air forming structure comprises:

[0066] The blades 161 are arranged on the baffle 120, and at least part of the blades 161 are located on the baffle 120, and the blades 161 extend towards the support 170.

[0067] Meanwhile, the roller brush module 100 further comprises a first motor arranged in the roller body 110, and the first motor drives the roller body 110, the baffle 120 and the blades 161 to rotate simultaneously.

[0068] When the blades 161 are arranged on the baffle 120, part of the blades 161 can be located on the roller body 110, and the blades 161 penetrate the baffle 120 and extend towards the support 170, or all the blades 161 can be located on the baffle 120. When part of the blades 161 are located on the roller body 110, the blades 161 can be integrally formed with the roller body 110, or the roller body 110 and the blades 161 can be connected through a bayonet connection, a welding connection, a convex and groove matching connection or a threaded connection. When all the blades 161 are located on the baffle 120, the blades 161 and the baffle 120 can be integrally formed, connected through a bayonet connection, a welding connection or a convex and groove matching connection.

[0069] It should be noted that the blades 161 are usually arranged obliquely, and the blades 161 are inclined to the direction in which the roller body 110 rotates. In this way, when the first motor (not shown) drives the roller body 110 to rotate, the baffle 120 and the blades 161 are also driven to rotate, and a centrifugal fan structure is formed in the space between the baffle 120 and the support 170. In this way, the airflow between the baffle 120 and the support 170 can prevent strip-shaped garbage from entering the space between the baffle 120 and the support 170, that is, the strip-shaped garbage can be prevented from winding around the connecting shaft 171 of the support 170.

[0070] It can be understood that the blades 161 extend towards the support 170, and the side of the blades 161 away from the baffle 120 is away from the side of the support 170 facing the baffle 120 by a first distance. Through the arrangement of the first distance, the blades 161 can be prevented from colliding with the support 170 when rotating, which can ensure the service life and structural stability of the support 170, and can also ensure the reliability of the operation of the roller brush module 100.

[0071] In an embodiment, when the air forming structure comprises a plurality of blades 161, the heights of the blades 161 are different; or the heights of at least two blades 161 are the same.

[0072] The height of the blade 161 is the distance between the end of the blade 161 away from the baffle 120 and the baffle 120.

[0073] When the air forming structure includes a plurality of blades 161, the distance between the end of the blade 161 away from the baffle 120 and the baffle 120 can be the same or different. That is, the first distance can be different, the first distance can also be the same, and the first distance can be selected as any value between 1 mm and 3 mm as long as the space between the baffle 120 and the support 170 forms an air flow. At the same time, the plurality of blades 161 are arranged around the central axis of the roller body 110, and the distance between the plurality of blades 161 is not limited, that is, the plurality of blades 161 can be uniformly arranged in a ring shape on the baffle 120 (roller body 110), and the plurality of blades 161 can be non-uniformly arranged on the baffle 120 (roller body 110). When the blades 161 are non-uniformly arranged, although the air flow is not uniformly applied in the space between the baffle 120 and the support 170, the air flow can still be generated to prevent the strip-shaped garbage from winding around the connecting shaft 171 of the support 170.

[0074] In a feasible implementation, the roller body 110, the baffle 120, and the support 170 are arranged in a roller brush shell, and the roller brush shell is configured on a main machine shell of an automatic cleaning device.

[0075] The roller brush shell is provided with a first air forming space, and the air forming structure is arranged in the first air forming space. The air forming structure includes the blades 161, a second motor, and a second pipeline. The second motor drives at least one blade 161 to rotate to form an air flow, and the air flow is introduced to the space between the support 170 and the baffle 120 through the second pipeline.

[0076] The main machine shell is provided with a second air forming space, and the air forming structure is arranged in the second air forming space. The air forming structure includes the blades 161, a third motor, and a third pipeline. The third motor drives at least one blade 161 to rotate to form an air flow, and the air flow is introduced to the space between the support 170 and the baffle 120 through the third pipeline.

[0077] Specifically, the first air forming space is enclosed by the surrounding plate and the roller brush shell, and the air forming structure is arranged in the first air forming space. At the same time, one end of the second pipeline is arranged in the first air forming space, and the other end of the second pipeline is connected to the space between the support 170 and the baffle 120, so as to introduce the air flow formed by the air forming structure in the first air forming space to the space between the support 170 and the baffle 120. It should be noted that the first air forming space can be located in the axial direction of the roller body 110, and the first air forming space can also be located in the radial direction of the roller body 110.

[0078] It should be pointed out that the air forming structure at this time should also include a mounting plate, the blade 161 is arranged on the mounting plate, and the mounting plate is located in the first air forming space. At this time, an additional power structure needs to be provided, which is a second motor (not shown). The fixed end of the second motor is arranged on the brush roll housing, and the output shaft of the second motor is fixedly connected with the mounting plate. The blade 161 is arranged on the mounting plate. In this way, the mounting plate and the blade 161 are driven to rotate by the rotation of the second motor, so as to form an air flow in the first air forming space. The air flow is introduced between the bracket 170 and the baffle 120 through the second pipeline, so as to prevent the hair from staying near the bracket 170. The mounting plate can be circular, square, rectangular, or any other irregular shape, as long as it does not scratch the side wall of the first air forming space during rotation of the blade 161.

[0079] When the first air forming space is located in the axial direction of the roller body 110, the distance between the first air forming space and the bracket 170 is relatively short, so that the length of the second pipeline can be effectively shortened. When the first air forming space is located in the radial direction of the roller body 110, although the length of the second pipeline is increased, the area of the brush roll module 100 on the cleaning plane can be reduced, that is, the floor area of the automatic cleaning device 200 can be reduced. By arranging the air forming structure, an air flow can be formed between the bracket 170 and the baffle 120. On the one hand, the strip-shaped garbage near the bracket 170 can be blown to the center of the roller body 110, so that the roller body 110 can clean the strip-shaped garbage into the containing box. On the other hand, the strip-shaped garbage can also be prevented from winding around the connecting shaft 171 of the bracket 170.

[0080] It can be understood that the blade 161 of the air forming structure and the surrounding plate of the first air forming space have a certain distance, that is, the blade and the first air forming space are in a clearance fit. Such an arrangement can prevent the blade 161 from colliding with the surrounding plate of the first air forming space during rotation. On the one hand, the service life and the stability of the first air forming space can be ensured. On the other hand, the reliability of the operation of the brush roll module 100 can be ensured. Meanwhile, when the air forming structure includes a plurality of blades 161, the heights of the plurality of blades 161 can be the same or different. The height of the blade 161 refers to the distance between the end of the blade 161 away from the mounting plate and the mounting plate. Meanwhile, the plurality of blades 161 can be uniformly arranged in a ring shape along the output shaft of the second motor, or can be non-uniformly arranged in a ring shape. As long as an air flow can be formed in the first air forming space, no other restrictions are made.

[0081] In another embodiment, the second air making space is enclosed by the enclosure and the main machine housing, the air making structure is arranged in the second air making space, and one end of the third pipeline is arranged in the second air making space, and the other end of the third pipeline is connected between the support 170 and the baffle 120, so as to guide the air formed by the air making structure in the second air making space to the space between the support 170 and the baffle 120. It should be noted that the second air making space can be located in the axial direction of the roller body 110, and the second air making space can also be located in the radial direction of the roller body 110.

[0082] Specifically, at this time, the air making structure should also include a support plate, the blades 161 are arranged on the support plate, the support plate is arranged in the second air making space, and the support plate is located in the second air making space. At this time, an additional power structure needs to be arranged, which is a third motor (not shown), the fixed end of the third motor is arranged on the main machine housing, the output shaft of the third motor is fixedly connected with the support plate, and the blades 161 are arranged on the support plate. In this way, the rotation of the third motor drives the support plate and the blades 161 to rotate, forming an air flow in the second air making space, and the air flow is guided to the space between the support 170 and the baffle 120 through the third pipeline, so as to prevent the hair from staying near the support 170. The support plate can be circular, square, rectangular, or any other irregular shape, as long as it does not scratch the side wall of the second air making space during the rotation of the support plate and the blades 161.

[0083] It should be noted that when the second air making space is located in the axial direction of the roller body 110, the second air making space is closer to the support 170, which can effectively shorten the length of the third pipeline; when the second air making space is located in the radial direction of the roller body 110, although the length of the third pipeline increases, the area of the roller brush module 100 on the cleaning plane can be reduced, that is, the floor area of the automatic cleaning device 200 can be reduced. By arranging the air making structure between the support 170 and the baffle 120, on the one hand, the strip-shaped garbage near the support 170 can be blown to the center of the roller body 110, so as to facilitate the roller body 110 to clean the strip-shaped garbage into the containing box, and on the other hand, the strip-shaped garbage can be prevented from winding around the connecting shaft 171 of the support 170.

[0084] It can be understood that the blade 161 of the air forming structure has a certain distance from the surrounding plate of the second air forming space, that is, the blade and the first air forming space are gap-fitted, which can avoid the blade 161 from colliding with the surrounding plate of the second air forming space when rotating, on the one hand, to ensure the service life and structural stability of the second air forming space, and on the other hand, to ensure the reliability of the working of the roller brush module 100. At the same time, when the air forming structure includes a plurality of blades 161, the heights of the plurality of blades 161 can be the same or different, and the height of the blade 161 refers to the distance between the end of the blade 161 away from the support plate and the support plate. At the same time, the plurality of blades 161 can be uniformly arranged in a ring shape along the output shaft of the third motor, or can be non-uniformly arranged in a ring shape, which can form an air flow in the second air forming space, without other restrictions.

[0085] It should be noted that the above-mentioned three air forming structure setting forms include at least one, or can include two, or can include three air forming structure setting forms. When including two air forming structure setting forms, that is, simultaneously setting air forming structures on the baffle 120 and in the first air forming space, or simultaneously setting air forming structures on the baffle 120 and in the second air forming space, or simultaneously setting air forming structures in the first air forming space and the second air forming space. The setting mode of the plurality of air forming structures can better form an air flow near the support 170, but an excessive air flow will also affect the cleaning of the dirt on the surface to be cleaned by the roller body 110, so the parameters of different power structures and different air forming structure setting modes are selected according to actual needs.

[0086] It can be understood that fans can also be arranged in the first air forming space and the second air forming space to form an air volume in the first air forming space and the second air forming space, and the air volume in the first air forming space is introduced between the support 170 and the baffle 120 through the second pipeline; similarly, the air volume in the second air forming space is introduced between the support 170 and the baffle 120 through the third pipeline, which can also achieve the purpose of avoiding the strip-shaped garbage from winding around the connecting shaft of the support 170 in the present application, and also belongs to the protection scope of the present application.

[0087] FIG. 4 is a schematic view of an air supply structure according to an embodiment of the present application; and FIG. 5 is a schematic view of an air supply structure according to another embodiment of the present application.

[0088] In a feasible implementation, as shown in FIGS. 4 and 5, the projection of the blade 161 on a plane perpendicular to the rotation axis of the blade 161 is in the shape of a rectangle, an arc, a triangle, a polygon, or other irregular shapes.

[0089] It should be noted that the projection of the blade 161 on a plane perpendicular to the rotation axis of the blade can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes. That is, the shape of the blade 161 is not limited.

[0090] It can be understood that when the wind forming structure includes a plurality of blades 161, the plurality of blades 161 can be of the same shape or different shapes, that is, the plurality of blades 161 can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes at the same time, or the plurality of blades 161 can be rectangular, arc-shaped, triangular, polygonal, or other irregular shapes respectively.

[0091] FIG. 6 is a schematic view of a wind forming structure according to another embodiment of the present application.

[0092] As shown in FIG. 6, in the present application, one end of the blade 161 close to the rotation center is the first end, and the other end of the blade 161 away from the rotation center is the second end. The distance between the first end and the second end can be the same or different. That is, when the distance between the first end and the second end is set as the length of the blade 161, the length of the blade 161 can be the same or different, and the blades 161 of different lengths can be arranged at intervals, or the blades 161 of the same length can be arranged adjacent to each other, as long as the blade 161 can generate wind after rotation. The length of the blade 161 is not limited.

[0093] In the present embodiment, the blade 161 can be arranged as any integer.

[0094] In a feasible implementation, the number of blades 161 is not more than 30. Too many blades 161 will increase the burden of the power structure and affect the service life of the power structure. At the same time, too many blades 161 will also bring greater noise and affect the user experience. Therefore, the blade 161 can be selected as any integer not more than 30.

[0095] In a feasible implementation, a single blade 161 includes varying heights.

[0096] That is, the height of the blade 161 from the end close to the rotation center to the end away from the rotation center can vary, that is, the height of the first section is the first height, the height of the second section is the second height, and the height of the Nth section is the Nth height, and the heights are connected in transition. It can be seen that such a blade 161 arrangement is also within the protection scope of the present application, as long as it can ensure that the rotation of the rotation structure drives the rotation of the blade to generate a certain amount of wind.

[0097] In a feasible implementation, the roller brush module 100 further includes a cleaning part arranged on the outer periphery of the roller body 110, and the cleaning part 110 is used to bring up dirt on the ground to be cleaned.

[0098] The cleaning part is arranged on the outer periphery of the roller body 110 and protrudes from the outer peripheral surface of the roller body 110, so that the cleaning part can be in contact with the surface to be cleaned, and the dirt on the surface to be cleaned can be brought up by the cleaning part, thereby achieving the purpose of cleaning the surface to be cleaned by the roller brush module 100.

[0099] In an embodiment, the cleaning part comprises:

[0100] The first cleaning member 130 is arranged on the outer periphery of the roller body 110 in a spiral shape.

[0101] The second cleaning member 140 is arranged on the outer periphery of the roller body 110 in a spiral shape, and the second cleaning member 140 is arranged at intervals with the first cleaning member 130.

[0102] It should be noted that the first cleaning member 130 is a rubber strip, and the second cleaning member 140 is a brush. During the rotation of the first cleaning member 130 and the second cleaning member 140, the second cleaning member 140 can be tilted towards the first cleaning member 130, and the first cleaning member 130 supports the second cleaning member 140. On the one hand, the tilting of the brush affects the cleaning effect of the roller brush module 100, and on the other hand, the use of the rubber strip and the brush can improve the cleaning efficiency. For example, the rubber strip is used to clean granular garbage, and the brush is used to clean dust and strip-shaped garbage. At the same time, the use of the first cleaning member 130 and the second cleaning member 140 can prolong the length of the strip-shaped garbage wound on the brush, that is, the first cleaning member 130 has a certain supporting effect on the strip-shaped garbage. Such a design is more convenient for cleaning the strip-shaped garbage on the brush, which can improve the cleaning efficiency of the brush and prolong the cleaning time of the brush, thereby improving the user experience.

[0103] The first cleaning member 130 and the second cleaning member 140 are arranged on the outer periphery of the roller body 110 in a spiral shape, which can increase the contact area between the cleaning part and the surface to be cleaned, and improve the cleaning effect and efficiency of the cleaning part. It should be understood that the spiral angles of the first cleaning member 130 and the second cleaning member 140 are the same, that is, the spiral angles are the same. On the one hand, it can ensure the cleaning effect of the cleaning part, and on the other hand, it can improve the appearance effect of the roller brush module 100.

[0104] It should be understood that the first cleaning member 130 and the roller body 110 can be connected by insertion, for example, a groove with the same shape as the first cleaning member 130 is arranged on the roller body 110, and a protrusion is arranged on the first cleaning member 130. The protrusion and the groove are connected to realize the fixed connection of the first cleaning member 130 and the roller body 110. The connection can also be realized by welding or adhesive bonding. Similarly, the second cleaning member 140 can also be connected with the roller body 110 by insertion, welding or adhesive bonding.

[0105] In one possible implementation, the first cleaning member 130 includes a first end and a second end, the first end of the first cleaning member 130 is arranged on the roller body 110, and the second end of the first cleaning member 130 is arranged away from the roller body 110. The second cleaning member 140 includes a first end and a second end, the first end of the second cleaning member 140 is arranged on the roller body 110, and the second end of the second cleaning member 140 is arranged away from the roller body 110. The distance between the first end of the first cleaning member 130 and the first end of the second cleaning member 140 is greater than the distance between the second end of the first cleaning member 130 and the second end of the second cleaning member 140.

[0106] The distance between the first end of the first cleaning member 130 and the first end of the second cleaning member 140 is greater than the distance between the second end of the first cleaning member 130 and the second end of the second cleaning member 140. That is, the end of the second cleaning member 140 away from the central axis of the roller body 110 is closer to the end of the first cleaning member 130 away from the central axis of the roller body 110. Such an arrangement can make the second end of the second cleaning member 140 closer to the second end of the first cleaning member 130 during rotation of the roller brush module 100, that is, the gap between the first cleaning member 130 and the second cleaning member 140 is smaller, which can hinder the strip-shaped garbage from winding around the brush, reduce the risk of the cleaning part winding the strip-shaped garbage, and thus improve the cleaning effect of the roller brush module 100.
