TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a roller brush device for a cleaning equipment, a cleaning equipment and a cleaning system. BACKGROUND

[0002] The cleaning equipment can greatly release people's hands and reduce the burden of people's housework. For example, the sweeper can use the motor to drive the blade to rotate at high speed, generate air negative pressure in the sealed shell, and then suck up the dust through the external dust suction pipe.

[0003] However, in the related art, the roller brush of the cleaning equipment is easily entangled and stuck by hair during cleaning, which affects the working stability of the cleaning equipment. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a roller brush device for a cleaning equipment, a cleaning equipment and a cleaning system, which can solve the problem that the roller brush of the cleaning equipment is easily entangled and stuck by hair during cleaning in the related art, which affects the working stability of the cleaning equipment.

[0005] In order to achieve the above purpose, the present application provides the following technical scheme:

[0006] The first aspect of the present application provides a roller brush device for a cleaning equipment, which comprises:

[0007] The first roller brush comprises a first end portion and a second end portion opposite in the axial direction;

[0008] The first cutting assembly and the first roller brush rotate in the first rotation direction under the driving of the driving assembly of the cleaning equipment, and the first cutting assembly is used to cut the hair entangled on the first end portion during rotation;

[0009] The first cutting assembly and the first roller brush are arranged to have a speed difference when rotating under the driving of the driving assembly.

[0010] The present application provides a roller brush device, which drives the first cutting assembly and the first roller brush to rotate in the first rotation direction by using the driving assembly of the cleaning equipment, so that the first cutting assembly and the first roller brush form relative rotation at the cutting position where they approach each other, which can facilitate the first cutting assembly to cut the hair on the first end portion of the first roller brush, thereby avoiding the first end portion of the first roller brush from being stuck and unable to rotate normally due to hair entanglement, and ensuring the working stability of the cleaning equipment.

[0011] In addition, by making the first cutting assembly and the first roller brush have a speed difference when rotating under the driving of the driving assembly, the relative rotation speed of the first cutting assembly and the first roller brush at the cutting position can be larger, so as to help improve the cutting efficiency of the first cutting assembly on the hair wound on the first end of the first roller brush, further prevent the first roller brush from being wound by the hair, and improve the working stability of the cleaning device.

[0012] Based on the above technical solutions, the application can also be improved as follows.

[0013] In a possible implementation, the roller brush device further comprises a first transmission assembly, the first transmission assembly rotates under the driving of the first roller brush;

[0014] The first cutting assembly is in transmission connection with the first transmission assembly, and the first cutting assembly rotates in the first rotation direction under the driving of the first transmission assembly.

[0015] In this way, the roller brush device uses the first transmission assembly to drive the first cutting assembly to rotate in the first rotation direction with the first roller brush, so as to realize linkage between the first roller brush and the first cutting assembly, avoid independent rotation between the first cutting assembly and the first roller brush, simplify the driving structure, reduce the space occupation of the roller brush device, simplify the driving process of the first cutting assembly and the first roller brush, and reduce the manufacturing cost.

[0016] In addition, the first transmission assembly is used to drive the first roller brush and the first cutting assembly, so as to ensure the consistency of the first roller brush and the first cutting assembly during rotation, and improve the working efficiency of the roller brush device.

[0017] In a possible implementation, the first transmission assembly comprises:

[0018] A driving gear is arranged at the first end of the first roller brush, and rotates in a first rotation direction under the driving of the first roller brush;

[0019] A trapezoidal gear is in meshing connection with the driving gear and rotates in a second rotation direction under the driving of the driving gear, and the first rotation direction and the second rotation direction are opposite;

[0020] An output gear is in meshing connection with the trapezoidal gear and arranged at the first cutting assembly, and the output gear is used to drive the first cutting assembly to rotate in the first rotation direction.

[0021] Thus, the first transmission assembly can drive the first cutting assembly to rotate in the first rotation direction along with the first roller brush by using the meshing transmission among the driving gear, the trapezoidal gear and the output gear, so that the first cutting assembly and the first roller brush rotate in opposite directions at the cutting position.

[0022] In addition, the meshing transmission among the driving gear, the trapezoidal gear and the output gear can realize the linkage between the first cutting assembly and the first roller brush by using a small number of components, facilitate the assembly of the roller brush device, reduce the manufacturing cost of the roller brush device, improve the assembly efficiency of the roller brush device, and reduce the manufacturing cost of the cleaning equipment.

[0023] In a possible implementation, the trapezoidal gear comprises:

[0024] a first tooth portion engaged with the driving gear, wherein the outer diameter of the first tooth portion is greater than the outer diameter of the driving gear;

[0025] a second tooth portion coaxially arranged with the first tooth portion, wherein the second tooth portion rotates along with the first tooth portion, and the outer diameter of the second tooth portion is less than the outer diameter of the first tooth portion.

[0026] Thus, by making the outer diameter of the first tooth portion on the trapezoidal gear greater than the outer diameter of the driving gear, the gear ratio between the first tooth portion and the driving gear can be increased, and the rotation speed of the first roller brush transmitted from the driving gear to the first tooth portion can be slowed down. After being transmitted through the first transmission assembly, the rotation speed of the first cutting assembly can be reduced relative to the rotation speed of the first roller brush, so that the rotation speed of the first cutting assembly is lower than the rotation speed of the first roller brush. In addition, since the movement directions of the first cutting assembly and the first roller brush at the cutting position are opposite, the relative rotation speed between the first cutting assembly and the first roller brush can be further increased, and the cutting efficiency of the first end portion of the first roller brush can be further improved.

[0027] In addition, since the rotation speed is reduced after being transmitted through the first transmission assembly, the torque transmitted to the first cutting assembly through the first transmission assembly can be increased, so that the first cutting assembly can overcome greater cutting resistance on the basis of improving the relative movement speed between the first cutting assembly and the first roller brush, and the cutting ability of the first cutting assembly to hair can be improved.

[0028] By making the outer diameter of the second tooth portion less than the outer diameter of the first tooth portion, the volume of the second tooth portion can be reduced under the condition of ensuring the same rotation speed, and the space occupation of the trapezoidal gear can be reduced.

[0029] In a possible implementation, the outer diameter of the output gear is greater than the outer diameter of the second tooth portion.

[0030] In this way, by making the outer diameter of the output gear larger than the outer diameter of the second tooth part, the gear ratio can be further increased, the rotation speed transmitted by the first transmission assembly to the first cutting assembly can be further slowed down, the torque transmitted by the first transmission assembly to the first cutting assembly can be further increased, the relative rotation speed between the first cutting assembly and the first rolling brush can be further expanded, and the first cutting assembly can overcome greater cutting resistance, thereby improving the cutting ability of the first cutting assembly on the hair wound around the first end portion.

[0031] In a possible implementation, the first cutting assembly comprises:

[0032] A transmission shaft connected to the first transmission assembly and configured to rotate in the first rotation direction under the driving of the first transmission assembly;

[0033] A blade provided on the transmission shaft and having a blade edge facing the outer surface of the first end portion, the blade edge being configured to cut the hair wound around the first end portion.

[0035] By configuring the first cutting assembly with the transmission shaft and the blade, the structure of the first cutting assembly can be simplified, the assembly efficiency of the first cutting assembly can be improved, and the manufacturing cost of the first cutting assembly can be reduced, so that the structure of the cleaning device can be simplified, and the assembly efficiency of the cleaning device can be improved.

[0036] In a possible implementation, the blade edge is an arc-shaped edge curved away from the transmission shaft.

[0037] The vertex of the arc-shaped edge is configured to cut the hair on the first end portion in the radial direction of the transmission shaft.

[0038] In this way, by configuring the blade edge of the blade as an arc-shaped edge curved away from the transmission shaft, and making the vertex of the arc-shaped edge cut the hair on the first end portion in the radial direction of the transmission shaft, the contact area between the blade and the surface of the first end portion can be reduced, so that the contact resistance between the blade edge and the hair can be reduced, the cutting resistance of the blade on the hair can be reduced, and the cutting efficiency of the first cutting assembly on the hair around the first end portion can be improved.

[0039] In a possible implementation, the extending direction of the blade edge is a first direction, the first direction intersects with the axis direction of the transmission shaft, and the axis direction of the transmission shaft is the same as the axis direction of the first rolling brush.

[0040] In the case that the axis direction of the transmission shaft is the same as the axis direction of the first rolling brush, by intersecting the extending direction of the blade with the axis direction of the transmission shaft, the contact area of the blade and the surface of the first end portion can be reduced, the contact area with the hair wound on the first end portion can be reduced, the blade and the hair are reduced from line contact to nearly point contact, the cutting resistance of the blade when cutting the hair is reduced, and the cutting efficiency of the first cutting assembly is improved.

[0041] In a possible implementation, the blade has a plurality, and the plurality of blades are arranged along the circumference of the transmission shaft.

[0044] Alternatively, at least part of the adjacent blades are arranged with a crossing.

[0047] In a possible implementation, along the axis direction of the transmission shaft, the vertexes of the arc-shaped blades of the blades are located on the same circle.

[0048] In this way, by locating the vertexes of the arc-shaped blades of all the blades on the same circle, it can be ensured that the vertexes of the arc-shaped blades of each blade can cut the hair on the first end portion, and the cutting efficiency of the first cutting assembly can be improved.

[0049] In a possible implementation, along the axis direction of the transmission shaft, the two adjacent blades do not overlap.

[0050] In this way, the spacing between the two adjacent blades can be appropriately widened while ensuring that a plurality of blades are arranged along the circumference of the transmission shaft and ensuring the cutting efficiency of the hair, the number of blades installed can be reduced, so that the manufacturing cost of the first cutting assembly can be reduced, and the manufacturing cost of the rolling brush device can be reduced.

[0051] Alternatively, along the axis direction of the transmission shaft, the two adjacent blades partially overlap.

[0052] If the extending direction of the blade intersects with the axial direction of the transmission shaft, the number of the blades installed on the transmission shaft can be increased by making the two adjacent blade portions on the transmission shaft overlap, so that the cutting frequency of the hair wound around the first end portion can be increased, and the cutting efficiency of the first cutting assembly can be improved.

[0053] In a possible implementation, the rolling brush device further comprises a mounting cover, and the cover is arranged on at least part of the first cutting assembly.

[0054] In this way, the rolling brush device can avoid collision between the first cutting assembly and other structures in the rolling brush device or the cleaning device during operation, so that damage to the first cutting assembly or other components can be avoided.

[0055] In this way, the rolling brush device can reduce the probability of the user being cut by the first cutting assembly when disassembling the first cutting assembly or other components in the rolling brush device.

[0056] In a possible implementation, the rolling brush device further comprises:

[0057] The second transmission assembly is driven to rotate by the first rolling brush;

[0058] The second cutting assembly is in transmission connection with the second transmission assembly, and is driven to rotate in the first rotating direction by the second transmission assembly, and the second cutting assembly is configured to cut the hair wound around the second end portion during rotation.

[0059] The second cutting assembly and the first rolling brush are configured to have a speed difference when rotating under the drive of the drive assembly.

[0060] In this way, the second cutting assembly is arranged at the second end portion of the first rolling brush, so that the hair wound around the second end portion of the first rolling brush can be cut by the second cutting assembly, the cutting effect of the hair at both ends of the first rolling brush can be further improved, the probability of the first rolling brush being wound and stuck by the hair during use can be reduced, the working stability of the first rolling brush is improved, and the working stability of the rolling brush device is improved.

[0061] The second transmission assembly is arranged, and the first rolling brush drives the second cutting assembly to rotate through the second transmission assembly, so that linkage between the first rolling brush and the second cutting assembly can be achieved, independent rotation between the second cutting assembly and the first rolling brush can be avoided, the driving structure is simplified, the space occupation of the rolling brush device is reduced, the driving process of the second cutting assembly and the first rolling brush is simplified, and the manufacturing cost is reduced.

[0062] In addition, the first roller brush and the second cutting assembly are drivingly connected through the second transmission assembly, which can ensure consistency of the first roller brush and the second cutting assembly during rotation, and improve the working efficiency of the roller brush device.

[0063] In addition, the second cutting assembly and the first roller brush have a speed difference when rotating under the driving of the driving assembly, which can make the relative rotation speed of the second cutting assembly and the first roller brush at the cutting position larger, thereby improving the cutting efficiency of the second cutting assembly on the hair wound around the second end of the first roller brush, further preventing the first roller brush and the roller brush device from being wound by the hair, and improving the working stability of the cleaning equipment.

[0071] By setting the third transmission assembly and enabling the second roller brush to drive the third cutting assembly to rotate through the third transmission assembly, linkage between the second roller brush and the third cutting assembly can be achieved, independent rotation between the third cutting assembly and the second roller brush can be avoided, the driving structure is simplified, the space occupation of the roller brush device is reduced, the driving process of the third cutting assembly and the second roller brush is simplified, and manufacturing cost is reduced.

[0109] As described in the background, in the related art, the roller brush of the cleaning device is easily entangled and stuck by hair during the cleaning process, and cannot work normally, affecting the working stability of the cleaning device.

[0110] The reason for the problem is that the roller brush device in the cleaning device in the prior art includes two roller brushes arranged side by side, and the two roller brushes are arranged at intervals. During rotation of the roller brushes, the debris on the ground is rolled into the interior of the cleaning device from the interval between the two roller brushes to achieve cleaning of the ground.

[0111] The two ends of the roller brush in the axial direction are connected to the driving member. Under the driving of the driving member, the roller brush rotates. However, during use of the roller brush, the hair on the ground is rolled into the two ends of the roller brush in the axial direction. Since the hair is not cleaned in time at the two ends of the roller brush, the hair wound at the two ends becomes more and more, which eventually causes the roller brush to be wound and stuck by the hair and unable to rotate, and causes the roller brush device to be unable to work normally, thereby affecting the working stability of the cleaning device.

[0112] To solve the above technical problems, the embodiments of the present application provide a roller brush device for a cleaning device, a cleaning device and a cleaning system. The roller brush device drives the first cutting assembly and the first roller brush to rotate in a first rotation direction by using the driving assembly of the cleaning device, so that the first cutting assembly and the first roller brush can form relative rotation at a position where the first cutting assembly and the first roller brush are close to each other, thereby facilitating the first cutting assembly to cut the hair at the first end of the first roller brush, avoiding the first end of the first roller brush from being stuck and unable to work normally due to the hair winding, and ensuring the working stability of the cleaning device.

[0113] In addition, the first cutting assembly and the first roller brush have a speed difference when rotating under the driving of the driving assembly. This can make the relative rotation speed of the first cutting assembly and the first roller brush at the cutting position greater, thereby helping to improve the efficiency of the first cutting assembly in cutting the hair wound at the first end of the first roller brush, further preventing the first roller brush from being wound by the hair, and improving the working stability of the cleaning device.

[0114] In order 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 described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0115] Reference Figures 1 to 4 The embodiments of the present application provide a roller brush device 11 for a cleaning device 10. The cleaning device 10 can be a self-moving cleaning device, such as a sweeper or a sweeping robot. The roller brush device 11 can include a first roller brush 100 and a first cutting assembly 200.

[0116] The first rolling brush 100 can include a first end portion 110 and a second end portion 120 opposite to each other in the axial direction, and the first end portion 110 and the second end portion 120 can be rotatably connected to the bottom shell 13 of the cleaning device 10.

[0117] The first cutting assembly 200 and the first rolling brush 100 are rotated in a first rotation direction (e.g., direction M in FIG. 1) under the driving of the driving assembly 12 of the cleaning device 10, and the first cutting assembly 200 is configured to cut the hair wound around the first end portion 110 during the rotation. Figure 3

[0118] The embodiments of the present application provide a rolling brush device 11, which drives the first cutting assembly 200 and the first rolling brush 100 to rotate in a first rotation direction by using the driving assembly 12 of the cleaning device 10, so that the first cutting assembly 200 and the first rolling brush 100 can be relatively rotated at a cutting position where the first cutting assembly 200 and the first rolling brush 100 are close to each other, and the first cutting assembly 200 can cut the hair of the first end portion 110 of the first rolling brush 100, so that the first end portion 110 of the first rolling brush 100 cannot be stuck and cannot work normally due to the hair wound around the first end portion 110, and the working stability of the cleaning device 10 can be ensured.

[0119] In some embodiments, the driving assembly 12 can have two independent driving members, and the first cutting assembly 200 and the first rolling brush 100 are independently driven to rotate by one of the driving members, so that the control accuracy of the first cutting assembly 200 and the first rolling brush 100 can be improved.

[0120] Alternatively, the driving assembly 12 can have one driving member, so that the first cutting assembly 200 and the first rolling brush 100 are driven by one driving member, so that the number of parts can be reduced and the structure can be simplified.

[0121] In some embodiments, the first cutting assembly 200 and the first rolling brush 100 are configured to have a speed difference when rotating under the driving of the driving assembly 12.

[0122] When the first cutting assembly 200 and the first rolling brush 100 are driven by two independent driving members in the driving assembly 12, respectively, the rotation speed of the first cutting assembly 200 and the rotation speed of the first rolling brush 100 can be independently adjusted, so that the adjustment accuracy of the rotation speed can be improved.

[0123] When the first cutting assembly 200 and the first rolling brush 100 are driven by one driving member in the driving assembly 12, a speed difference between the first cutting assembly 200 and the first rolling brush 100 can be achieved through a speed reduction assembly.

[0124] ​In this way, by making the first cutting assembly 200 and the first rolling brush 100 have a speed difference when rotating under the driving of the driving assembly 12, the relative rotation speed of the first cutting assembly 200 and the first rolling brush 100 at the cutting position can be greater, thereby helping to improve the efficiency of the first cutting assembly 200 in cutting the hair wound around the first end 110 of the first rolling brush 100, further preventing the first rolling brush 100 from being wound by hair, and improving the working stability of the cleaning device 10.

[0125] With reference to Figure 3 and Figure 4 In some embodiments, if the first rolling brush 100 and the first cutting assembly 200 are driven by the same driving member in the driving assembly 12, the rolling brush device 11 can further include a first transmission assembly 300 that rotates under the driving of the first rolling brush 100.

[0126] The first cutting assembly 200 is in transmission connection with the first transmission assembly 300, and the first cutting assembly 200 rotates in the first rotation direction under the driving of the first transmission assembly 300. By using the first transmission assembly 300 to drive the first rolling brush 100 and the first cutting assembly 200, the first transmission assembly 300 can make the rotation speed of the first cutting assembly 200 less than the rotation speed of the first rolling brush 100, so that there is a speed difference between the first rolling brush 100 and the first cutting assembly 200.

[0127] The first transmission assembly 300 can be a speed reducer, which can achieve a speed reduction effect through gear transmission cooperation.

[0128] In this way, the rolling brush device 11 uses the first transmission assembly 300 to drive the first rolling brush 100 to rotate in the first rotation direction, thereby achieving linkage between the first rolling brush 100 and the first cutting assembly 200, avoiding independent rotation between the first cutting assembly 200 and the first rolling brush 100, simplifying the driving structure, reducing the space occupation of the rolling brush device 11, simplifying the driving process of the first cutting assembly 200 and the first rolling brush 100, and reducing manufacturing costs.

[0129] In addition, by using the first transmission assembly 300 to drive the first rolling brush 100 and the first cutting assembly 200, the consistency of the first rolling brush 100 and the first cutting assembly 200 during rotation can be ensured, and the working efficiency of the rolling brush device 11 can be improved.

[0130] With reference to Figure 3 and Figure 4 In some embodiments, the first transmission assembly 300 can be a gear transmission assembly, and the first transmission assembly 300 can include a driving gear 310, a trapezoidal gear 320, and an output gear 330.

[0131] The driving gear 310 is arranged at the first end portion 110 of the first rolling brush 100, and rotates in a first rotation direction under the driving of the first rolling brush 100. The driving gear 310 can be fixedly connected with the first end portion 110 of the first rolling brush 100, or detachably connected with the first end portion 110 of the first rolling brush 100.

[0132] The trapezoidal gear 320 is engaged with the driving gear 310, and rotates in a second rotation direction under the driving of the driving gear 310. The first rotation direction and the second rotation direction (e.g., direction N in FIG. 3) are opposite. Figure 4

[0133] The output gear 330 is engaged with the trapezoidal gear 320, and is arranged at the first cutting assembly 200. The output gear 330 is used to drive the first cutting assembly 200 to rotate in the first rotation direction.

[0134] In some embodiments, the output gear 330 can be fixedly connected with the first cutting assembly 200, or detachably connected with the first cutting assembly 200.

[0135] In some examples, the axial direction of the driving gear 310, the axial direction of the trapezoidal gear 320, and the axial direction of the output gear 330 can be the same.

[0136] In this way, the first transmission assembly 300 can drive the first cutting assembly 200 to rotate in the first rotation direction along with the first rolling brush 100 by using the engagement transmission between the driving gear 310, the trapezoidal gear 320, and the output gear 330, so as to realize the opposite rotation directions of the first cutting assembly 200 and the first rolling brush at the cutting position.

[0137] In addition, the engagement transmission between the driving gear 310, the trapezoidal gear 320, and the output gear 330 can realize the linkage between the first cutting assembly 200 and the first rolling brush 100 by using a small number of components, facilitate the assembly of the rolling brush device 11, reduce the manufacturing cost of the rolling brush device 11, improve the assembly efficiency of the rolling brush device 11, and reduce the manufacturing cost of the cleaning equipment 10.

[0138] Reference Figure 3 and Figure 4 ​In some embodiments, the trapezoidal gear 320 can include a first tooth portion 321 and a second tooth portion 322, which can be coaxially arranged and arranged along the axial direction of the trapezoidal gear 320. The first tooth portion 321 and the second tooth portion 322 are relatively fixed. By using the trapezoidal gear 320, the number of components in the first transmission assembly 300 can be reduced, and the assembly efficiency of the rolling brush device 11 can be improved.

[0139] The first tooth portion 321 is engaged with the driving gear 310, and the outer diameter of the first tooth portion 321 is greater than the outer diameter of the driving gear 310. The second tooth portion 322 is coaxially arranged with the first tooth portion 321, and the second tooth portion 322 rotates under the drive of the first tooth portion 321. The outer diameter of the second tooth portion 322 is smaller than the outer diameter of the first tooth portion 321.

[0140] In this way, by making the outer diameter of the first tooth portion 321 on the trapezoidal gear 320 greater than the outer diameter of the driving gear 310, the gear ratio between the first tooth portion 321 and the driving gear 310 can be increased, and the rotation speed of the first rolling brush 100 transmitted from the driving gear 310 to the first tooth portion 321 can be slowed down. The rotation speed of the first cutting assembly 200 can be reduced after being transmitted through the first transmission assembly 300, relative to the rotation speed of the first rolling brush 100, so that the rotation speed of the first cutting assembly 200 can be lower than the rotation speed of the first rolling brush 100. In addition, since the movement directions of the first cutting assembly 200 and the first rolling brush 100 at the cutting position are opposite, the relative rotation speed between the first cutting assembly 200 and the first rolling brush 100 can be further increased, and the cutting efficiency of the first end portion 110 of the first rolling brush 100 can be further improved.

[0141] In addition, since the rotation speed is reduced after passing through the first transmission assembly 300, the torque transmitted to the first cutting assembly 200 through the first transmission assembly 300 is increased, so that the first cutting assembly 200 can overcome greater cutting resistance and improve the cutting ability of the first cutting assembly 200 on the hair, on the basis of improving the relative movement speed between the first cutting assembly 200 and the first rolling brush 100.

[0142] By making the outer diameter of the second tooth portion 322 smaller than the outer diameter of the first tooth portion 321, the volume of the second tooth portion 322 can be reduced under the condition of ensuring the same rotation speed, and it is helpful to reduce the space occupation of the trapezoidal gear 320.

[0143] Reference Figure 3 and Figure 4 In some embodiments, the outer diameter of the output gear 330 is greater than the outer diameter of the second tooth portion 322.

[0144] In this way, by making the outer diameter of the output gear 330 greater than the outer diameter of the second tooth portion 322, the gear ratio can be further increased, the rotational speed transmitted by the first transmission assembly 300 to the first cutting assembly 200 can be further slowed down, the torque transmitted by the first transmission assembly 300 to the first cutting assembly 200 can be further increased, the relative rotational speed between the first cutting assembly 200 and the first rolling brush 100 can be further expanded, and the first cutting assembly 200 can overcome greater cutting resistance, thereby improving the cutting ability of the first cutting assembly 200 on the hair wound around the first end portion 110.

[0145] With reference to Figure 5 and Figure 6 In some embodiments, the first cutting assembly 200 can include a transmission shaft 210 and a blade 220.

[0146] The transmission shaft 210 is connected to the first transmission assembly 300 for rotation in the first rotational direction under the driving of the first transmission assembly 300. If the first transmission assembly 300 has an output gear 330, the output gear 330 can be arranged on the transmission shaft 210. The axis direction of the transmission shaft 210 is the same as the axis direction of the first rolling brush 100.

[0147] The blade 220 is arranged on the transmission shaft 210, and the cutting edge 221 of the blade 220 faces the outer surface of the first end portion 110, which is used to cut the hair wound around the first end portion 110. The blade 220 can have one or more, and the more the number of blades 220, the more conducive to cutting the hair wound on the first end portion 110. By cutting the hair on the first end portion 110 by the blade 220, since the cutting edge 221 of the blade 220 is relatively sharp, it is helpful to cut the hair wound on the first end portion 110 and improve the cutting efficiency.

[0148] In this way, the transmission shaft 210 of the first cutting assembly 200 is connected to the first transmission assembly 300, so that the first transmission assembly 300 transmits power to the transmission shaft 210, and further drives the blade 220 to rotate in the first rotational direction through the transmission shaft 210, so as to realize the cutting of the hair on the first end portion 110 by the blade 220.

[0149] By arranging the first cutting assembly 200 as the transmission shaft 210 and the blade 220 cooperate, the structure of the first cutting assembly 200 can be simplified, the assembly efficiency of the first cutting assembly 200 can be improved, and the manufacturing cost of the first cutting assembly 200 can be reduced, so that the structure of the cleaning device 10 can be simplified, and the assembly efficiency of the cleaning device 10 can be improved.

[0150] In some embodiments, the first cutting assembly 200 can further comprise a plurality of blades, the blades being arranged on the transmission shaft 210 and being driven to rotate by the transmission shaft 210 to cut the hair wound on the first end portion 110 by the blades.

[0151] Referring to Figure 5 and Figure 6 In some embodiments, the cutting edge 221 is an arc-shaped edge curved away from the transmission shaft 210. The vertex of the arc-shaped edge is used to cut the hair on the first end portion 110 in the radial direction of the transmission shaft 210.

[0152] In this way, by arranging the cutting edge 221 of the blade 220 as an arc-shaped edge curved away from the transmission shaft 210 and making the vertex of the arc-shaped edge cut the hair on the first end portion 110 in the radial direction of the transmission shaft 210, the contact area between the blade 220 and the surface of the first end portion 110 can be reduced, the contact resistance between the cutting edge 221 and the hair can be reduced, the cutting resistance of the blade 220 to the hair can be reduced, and the cutting efficiency of the first cutting assembly 200 to the hair on the first end portion 110 can be improved.

[0153] In some embodiments, the length extension direction of the cutting edge 221 can be the same as the extension direction of the transmission shaft 210.

[0154] Referring to Figure 5 and Figure 6 In some embodiments, the length extension direction of the cutting edge 221 can be the same as the extension direction of the transmission shaft 210. Figure 5 In some embodiments, the length extension direction of the cutting edge 221 can be the same as the extension direction of the transmission shaft 210.

[0155] In some embodiments, the length extension direction of the cutting edge 221 can be the same as the extension direction of the transmission shaft 210.

[0156] In some embodiments, the length extension direction of the cutting edge 221 can be the same as the extension direction of the transmission shaft 210.

[0157] Referring to Figure 5 and Figure 6 In some embodiments, the blade 220 can have a plurality of blades 220 arranged along the circumferential direction of the transmission shaft 210. Alternatively, the plurality of blades 220 can be arranged along the circumferential direction of the transmission shaft 210 and uniformly spaced.

[0158] In this way, by arranging multiple blades 220 on the transmission shaft 210, the number of times of cutting the hair wound on the first end portion 110 by the first cutting assembly 200 can be increased, so that the cutting efficiency of the hair can be improved, and the working stability of the roller brush device 11 can be improved.

[0159] Reference Figure 5 and Figure 6 In some embodiments, every two adjacent blades 220 can be arranged at intervals.

[0160] The two adjacent blades 220 can be arranged at intervals and uniformly, so that the design and production of the first cutting assembly 200 can be facilitated.

[0161] In other embodiments, at least part of the adjacent blades 220 can be arranged in cross. Alternatively, at least one end of the two adjacent blades 220 is connected along the extension direction of the blade 220.

[0162] In this way, by arranging the two adjacent blades 220 at intervals, the number of blades 220 arranged on the transmission shaft 210 can be reduced, and the manufacturing cost of the roller brush device 11 can be reduced, while ensuring that the transmission shaft 210 is circumferentially arranged with blades 220 and ensuring the cutting efficiency.

[0163] Reference Figure 5 and Figure 6 In some embodiments, if the cutting edges 221 of the blades 220 are all arc-shaped edges, the vertices of the arc-shaped edges of the blades 220 can all be located on the same circle (such as the circle Q) along the axis direction of the transmission shaft 210. Figure 6

[0164] In this way, by arranging the vertices of the arc-shaped edges of all the blades 220 on the same circle, it can be ensured that the vertex of the arc-shaped edge of each blade 220 can cut the hair on the first end portion 110, and the cutting efficiency of the first cutting assembly 200 can be improved.

[0165] Reference Figure 5 and Figure 6 In some embodiments, the two adjacent blades 220 do not overlap along the axis direction of the transmission shaft 210. It should be noted that the two adjacent blades 220 do not overlap along the axis direction of the transmission shaft 210 means that the projections of the two adjacent blades 220 along the axis direction of the transmission shaft 210 do not overlap.

[0166] ​In this way, the installation number of the blades 220 can be reduced, the manufacturing cost of the first cutting assembly 200 can be reduced, and the manufacturing cost of the roller brush device 11 can be reduced.

[0167] With reference to Figure 6 The two adjacent blades 220 partially overlap along the axial direction of the transmission shaft 210. It should be noted that the two adjacent blades 220 partially overlap along the axial direction of the transmission shaft 210 means that the orthographic projections of the two adjacent blades 220 partially overlap along the axial direction of the transmission shaft 210.

[0168] If the extension direction of the blade edge 221 intersects the axial direction of the transmission shaft 210, by partially overlapping the two adjacent blades 220 on the transmission shaft 210, the installation number of the blades 220 on the transmission shaft 210 can be increased, the number of cutting operations on the hair wound on the first end portion 110 can be increased, and the cutting efficiency of the first cutting assembly 200 can be improved.

[0169] With reference to Figure 2 In some embodiments, the roller brush device 11 can further include a mounting cover 400, and the mounting cover 400 covers at least part of the first cutting assembly 200.

[0170] In this way, by providing the mounting cover 400 and covering at least part of the first cutting assembly 200 with the mounting cover 400, the first cutting assembly 200 can be prevented from colliding with the roller brush device 11 or other structures in the cleaning device 10 during operation, thereby preventing damage to the first cutting assembly 200 or other components.

[0171] By mounting at least part of the first cutting assembly 200 in the mounting cover 400, the probability of the user being cut by the first cutting assembly 200 when disassembling the first cutting assembly 200 or other components in the roller brush device 11 can be reduced.

[0172] With reference to Figure 4 In some embodiments, if the first cutting assembly 200 has the blades 220 and the transmission shaft 210, the mounting cover 400 can cover the blades 220 and allow the transmission shaft 210 to pass through, the transmission shaft 210 can rotate relative to the mounting cover 400, and the transmission shaft 210 can drive the blades 220 in the mounting cover 400 to rotate. By providing the mounting cover 400, the operator can be prevented from being cut by the blades 220 when disassembling the roller brush device 11.

[0173] In addition, since the transmission shaft 210 passes through the mounting cover 400, the mounting cover 400 can also limit the displacement of the transmission shaft 210. For example, when the transmission shaft 210 passes through the mounting cover 400, the mounting cover 400 can limit the axial movement and rotation of the transmission shaft 210 around the axial direction, avoid the transmission shaft 210 from being offset relative to the axial direction, improve the stability of the transmission shaft 210 during rotation, and further improve the working stability of the first cutting assembly 200.

[0174] With reference to Figure 2 and Figure 3 In some embodiments, the roller brush device 11 can further include a second transmission assembly 500a and a second cutting assembly 500b. The second transmission assembly 500a rotates under the drive of the first roller brush 100. The second cutting assembly 500b is in transmission connection with the second transmission assembly 500a, and rotates in the first rotation direction under the drive of the second transmission assembly 500a. The second cutting assembly 500b is used to cut the hair wound on the second end portion 120 during rotation. The second cutting assembly 500b and the first roller brush 100 are arranged to have a speed difference when rotating under the drive of the drive assembly 12.

[0175] In some embodiments, the specific structure of the second transmission assembly 500a and the first transmission assembly 300 and the cooperation mode with other components can be the same, and the structure of the second cutting assembly 500b and the first cutting assembly 200 and the cooperation mode with other components can be the same. Here, the second transmission assembly 500a and the second cutting assembly 500b will not be specifically expanded.

[0176] In this way, by arranging the second cutting assembly 500b on the second end portion 120 of the first roller brush 100, the hair wound on the second end portion 120 of the first roller brush 100 can be cut by the second cutting assembly 500b, which can further improve the cutting effect of the hair on both ends of the first roller brush 100, thereby reducing the probability of the first roller brush 100 being wound and stuck by the hair during use, improving the working stability of the first roller brush 100, and improving the working stability of the roller brush device 11.

[0177] By arranging the second transmission assembly 500a and enabling the first roller brush 100 to drive the second cutting assembly 500b to rotate through the second transmission assembly 500a, linkage between the first roller brush 100 and the second cutting assembly 500b can be achieved, independent rotation between the second cutting assembly 500b and the first roller brush 100 can be avoided, the drive structure is simplified, the space occupation of the roller brush device 11 is reduced, the drive process of the second cutting assembly 500b and the first roller brush 100 is simplified, and the manufacturing cost is reduced.

[0178] In addition, the first roller brush 100 and the second cutting assembly 500b are drivingly connected through the second transmission assembly 500a, which can ensure the consistency of the first roller brush 100 and the second cutting assembly 500b during rotation, and can improve the working efficiency of the roller brush device 11.

[0179] In addition, the second cutting assembly 500b and the first roller brush 100 have a speed difference when rotating under the driving of the driving assembly 12, which can make the relative rotation speed of the second cutting assembly 500b and the first roller brush 100 at the cutting position larger, thereby helping to improve the efficiency of the second cutting assembly 500b in cutting the hair wound on the second end portion 120 of the first roller brush 100, further preventing the first roller brush 100 and the roller brush device 11 from being wound by hair, and improving the working stability of the cleaning equipment 10.

[0180] Reference Figure 4 and Figure 5 In some embodiments, the roller brush device 11 can further include a second roller brush 800, which can include a third end portion 810 and a fourth end portion 820 opposite in the axial direction. The second roller brush 800 rotates in a second rotation direction (such as the N direction in Figure 4 ) under the driving of the driving assembly 12, and the second rotation direction is opposite to the first rotation direction. The axial direction of the first roller brush 100 is parallel to the axial direction of the second roller brush 800.

[0181] In this way, the roller brush device 11 is provided with the second roller brush 800, the axial direction of the second roller brush 800 is parallel to the axial direction of the second roller brush 800, and there is a gap between the first roller brush 100 and the second roller brush 800. The second roller brush 800 rotates in a direction opposite to the first roller brush 100, so that both roller brushes can roll the debris from the ground into the roller brush device 11 at the gap, achieving cleaning of the ground and improving the cleaning effect of the roller brush device 11.

[0182] Reference Figure 2 and Figure 3 In some embodiments, the roller brush device 11 can further include a third transmission assembly 600a and a third cutting assembly 600b. The third transmission assembly 600a rotates under the driving of the second roller brush 800. The third cutting assembly 600b is drivingly connected with the third transmission assembly 600a, and the third cutting assembly 600b rotates in the second rotation direction under the driving of the third transmission assembly 600a. The third cutting assembly 600b is used to cut the hair wound on the third end portion 810, and the third cutting assembly 600b and the second roller brush 800 are arranged to have a speed difference when rotating under the driving of the driving assembly 12.

[0183] In some embodiments, the structure of the third transmission assembly 600a and the first transmission assembly 300 and the matching mode with other components can be the same, and the structure of the third cutting assembly 600b and the first cutting assembly 200 and the matching mode with other components can be the same, and hereinafter, the third transmission assembly 600a and the third cutting assembly 600b will not be specifically expanded.

[0184] In this way, the roller brush device 11 drives the third cutting assembly 600b and the second roller brush 800 to rotate in the second rotation direction by using the driving assembly 12 of the cleaning device 10, so that the third cutting assembly 600b and the second roller brush 800 can form relative rotation at the cutting position between the third cutting assembly 600b and the second roller brush 800, thereby facilitating the third cutting assembly 600b to cut the hair of the third end portion 810 of the second roller brush 800, thereby avoiding the third end portion 810 of the second roller brush 800 being stuck and unable to rotate normally due to hair winding, and ensuring the working stability of the cleaning device 10.

[0185] By setting the third transmission assembly 600a and driving the third cutting assembly 600b to rotate by the second roller brush 800 through the third transmission assembly 600a, linkage between the second roller brush 800 and the third cutting assembly 600b can be achieved, independent rotation between the third cutting assembly 600b and the second roller brush 800 can be avoided, the driving structure is simplified, the space occupation of the roller brush device 11 is reduced, the driving process of the third cutting assembly 600b and the second roller brush 800 is simplified, and the manufacturing cost is reduced.

[0186] In addition, by driving the second roller brush 800 and the third cutting assembly 600b through the third transmission assembly 600a, the consistency of the second roller brush 800 and the third cutting assembly 600b during rotation can be ensured, and the working efficiency of the roller brush device 11 can be improved.

[0187] Reference Figure 2 and Figure 3 In some embodiments, the roller brush device 11 can further include a fourth transmission assembly 700a and a fourth cutting assembly 700b. The fourth transmission assembly 700a rotates under the driving of the second roller brush 800. The fourth cutting assembly 700b is in transmission connection with the fourth transmission assembly 700a, and the fourth cutting assembly 700b rotates in the second rotation direction under the driving of the fourth transmission assembly 700a. The fourth cutting assembly 700b is used to cut the hair wound on the fourth end portion 820. The fourth cutting assembly 700b and the second roller brush 800 are arranged to have a speed difference when rotating under the driving of the driving assembly 12.

[0188] In some embodiments, the fourth transmission assembly 700a and the first transmission assembly 300 can have the same structure and be matched with other components in the same way, and the fourth cutting assembly 700b and the first cutting assembly 200 can have the same structure and be matched with other components in the same way. Here, the fourth transmission assembly 700a and the fourth cutting assembly 700b will not be specifically expanded.

[0189] By providing the fourth cutting assembly 700b at the fourth end 820 of the second roller brush 800, the hair wound on the fourth end 820 of the second roller brush 800 can be cut by the fourth cutting assembly 700b, which can further improve the cutting effect of the hair at both ends of the second roller brush 800, thereby reducing the probability of the second roller brush 800 being wound and stuck by the hair during use, improving the working stability of the second roller brush 800, and improving the working stability of the roller brush device 11.

[0190] By providing the fourth transmission assembly 700a and enabling the second roller brush 800 to drive the fourth cutting assembly 700b to rotate through the fourth transmission assembly 700a, linkage between the second roller brush 800 and the fourth cutting assembly 700b can be achieved, independent rotation between the fourth cutting assembly 700b and the second roller brush 800 can be avoided, the driving structure is simplified, the space occupation of the roller brush device 11 is reduced, the driving process of the fourth cutting assembly 700b and the second roller brush 800 is simplified, and the manufacturing cost is reduced.

[0191] In addition, by drivingly connecting the second roller brush 800 and the fourth cutting assembly 700b through the fourth transmission assembly 700a, consistency of the second roller brush 800 and the fourth cutting assembly 700b during rotation can be ensured, and the working efficiency of the roller brush device 11 can be improved.

[0192] By enabling the fourth cutting assembly 700b and the second roller brush 800 to have a speed difference when rotating under the driving of the driving assembly 12, the relative rotation speed of the fourth cutting assembly 700b and the second roller brush 800 at the cutting position can be greater, which can help to improve the cutting efficiency of the fourth cutting assembly 700b on the hair wound on the fourth end 820 of the second roller brush 800, further prevent the second roller brush 800 and the roller brush device 11 from being wound by the hair, and improve the working stability of the cleaning equipment 10.

[0193] Reference Figure 1 and Figure 2 The embodiments of the present application also provide a cleaning equipment 10, which can be a self-moving cleaning equipment 10,

[0194] The cleaning device 10 can include a driving assembly 12 and the above-mentioned rolling brush device 11. The driving assembly 12 is configured to drive the first cutting assembly 200 and the first rolling brush 100 of the rolling brush device 11 to rotate in a first rotation direction;

[0195] The bottom shell 13 and the cover plate 14, the cover plate 14 covers the bottom shell 13, and the cover plate 14 and the bottom shell 13 form a mounting cavity, and the rolling brush device 11, the first transmission assembly 300 and the first cutting assembly 200 are arranged in the mounting cavity.
