Roller brush devices for cleaning equipment, cleaning equipment and cleaning systems
[0001] This application claims priority to Chinese Patent Application No. 202422810293.1, filed on November 18, 2024, entitled "Roller brush device for cleaning equipment, cleaning equipment and cleaning system", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of cleaning equipment technology, and in particular to a roller brush device, cleaning equipment and cleaning system for cleaning equipment. Background Technology
[0003] Cleaning equipment can greatly free people's hands and reduce the burden of housework. For example, a sweeper uses an electric motor to drive the blades to rotate at high speed, creating negative air pressure inside a sealed casing, and then sucks up dust and debris through an external suction pipe.
[0004] However, in the cleaning equipment mentioned above, the roller brush is easily entangled and jammed by hair during the cleaning process, which prevents it from working properly and affects the stability of the cleaning equipment. Summary of the Invention
[0005] This application provides a roller brush device, cleaning equipment, and cleaning system for cleaning equipment, which solves the problem that in the above-mentioned related technologies, the roller brush is easily entangled and jammed by hair during the cleaning process, thus failing to work properly and affecting the working stability of the cleaning equipment.
[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0007] A first aspect of this application provides a roller brush device for a cleaning equipment, comprising:
[0008] A first roller brush, the first roller brush including a first end and a second end opposite each other in the axial direction;
[0009] A first cutting component and a first roller brush rotate in a first rotation direction under the drive of a drive component of the cleaning device. The first cutting component is used to cut hair wrapped around the first end during rotation.
[0010] The first cutting component and the first roller brush are configured to have a speed difference when they rotate under the drive of the driving component.
[0011] This application provides a roller brush device. The roller brush device uses a driving component of a cleaning device to drive a first cutting component and a first roller brush to rotate along a first rotation direction. This allows the first cutting component and the first roller brush to rotate relative to each other at a cutting position where they are close to each other. This facilitates the first cutting component in cutting the hair at the first end of the first roller brush, thereby preventing the first end of the first roller brush from getting stuck due to hair entanglement and ensuring the working stability of the cleaning device.
[0012] In addition, by creating a speed difference between the first cutting component and the first roller brush when they rotate under the drive of the drive component, the relative rotation speed of the first cutting component and the first roller brush at the cutting position can be increased, thereby helping to improve the efficiency of the first cutting component in cutting the hair wrapped around the first end of the first roller brush, further preventing the first roller brush from being entangled by hair, and improving the working stability of the cleaning equipment.
[0013] Based on the above technical solution, the following improvements can be made to this application.
[0014] In one possible implementation, the roller brush device further includes a first transmission assembly that rotates under the drive of the first roller brush;
[0015] The first cutting component is connected to the first transmission component, and the first cutting component rotates along the first rotation direction under the drive of the first transmission component.
[0016] In this way, by using the first transmission component, the first roller brush drives the first cutting component to rotate in the first rotation direction, thereby realizing the linkage between the first roller brush and the first cutting component. This avoids independent rotation between the first cutting component and the first roller brush, simplifies the drive structure, reduces the space occupied by the roller brush, simplifies the driving process of the first cutting component and the first roller brush, and reduces manufacturing costs.
[0017] In addition, by connecting the first roller brush and the first cutting component through the first transmission assembly, the consistency of the first roller brush and the first cutting component during rotation can be ensured, thereby improving the working efficiency of the roller brush device.
[0018] In one possible implementation, the first transmission component includes:
[0019] A drive gear is disposed at the first end of the first roller brush, and the drive gear rotates along a first rotation direction under the drive of the first roller brush;
[0020] A trapezoidal gear meshes with the driving gear and rotates along a second rotation direction under the drive of the driving gear, wherein the first rotation direction and the second rotation direction are opposite;
[0021] An output gear meshes with the trapezoidal gear and is disposed on the first cutting assembly. The output gear is used to drive the first cutting assembly to rotate along the first rotation direction.
[0022] In this way, by using the meshing transmission between the driving gear, the trapezoidal gear and the output gear, the first transmission component enables the first cutting component to rotate along the first rotation direction with the first roller brush under the action of the first transmission component, so that the rotation directions of the first cutting component and the first roller brush are opposite at the cutting position.
[0023] In addition, the meshing method between the drive gear, trapezoidal gear and output gear can realize the linkage between the first cutting component and the first roller brush with fewer parts, which facilitates the assembly of the roller brush device, reduces the manufacturing cost of the roller brush device, improves the assembly efficiency of the roller brush device, and can reduce the manufacturing cost of the cleaning equipment.
[0024] In one possible implementation, the trapezoidal gear includes:
[0025] The first tooth meshes with the drive gear, and the outer diameter of the first tooth is larger than the outer diameter of the drive gear.
[0026] The second tooth is coaxially arranged with the first tooth and rotates under the drive of the first tooth. The outer diameter of the second tooth is smaller than the outer diameter of the first tooth.
[0027] In this way, by making the outer diameter of the first tooth on the trapezoidal gear larger than the outer diameter of the driving gear, the gear ratio between the first tooth and the driving gear can be increased, reducing the rotational speed of the first roller brush transmitted from the driving gear to the first tooth. This allows the rotational speed of the first cutting component to decrease relative to the rotational speed of the first roller brush after being transmitted through the first transmission component, thus making the rotational speed of the first cutting component lower than that of the first roller brush. Furthermore, since the first cutting component and the first roller brush move in opposite directions at the cutting point, the relative rotational speed between the first cutting component and the first roller brush can be further increased, further improving the cutting efficiency of the hair at the first end of the first roller brush.
[0028] In addition, since the rotational speed decreases when passing through the first transmission component, the torque transmitted to the first cutting component through the first transmission component will increase accordingly. This allows the first cutting component to overcome greater cutting resistance and improve its ability to cut hair, based on increasing the relative speed between the first cutting component and the first roller brush.
[0029] By making the outer diameter of the second tooth smaller than that of the first tooth, the volume of the second tooth can be reduced while maintaining the same rotational speed, which also helps to reduce the space occupied by the trapezoidal gear.
[0030] In one possible implementation, the outer diameter of the output gear is larger than the outer diameter of the second tooth.
[0031] In this way, by making the outer diameter of the output gear larger than the outer diameter of the second tooth, the gear ratio can be further increased, the rotational speed transmitted from the first transmission component to the first cutting component can be further reduced, the torque transmitted from the first transmission component to the first cutting component can be further increased, the relative rotational speed between the first cutting component and the first roller brush can be further expanded, and the first cutting component can overcome greater cutting resistance, thereby improving the cutting ability of the first cutting component to cut hair wrapped around the first end.
[0032] In one possible implementation, the first cutting component includes:
[0033] A drive shaft, connected to the first transmission assembly, is used to rotate around the first rotation direction under the drive of the first transmission assembly;
[0034] A blade is disposed on the drive shaft, with the cutting edge of the blade facing the outer surface of the first end, the cutting edge being used to cut the hair wrapped around the first end.
[0035] In this way, the drive shaft of the first cutting component is connected to the first transmission component, so that the first transmission component can transmit power to the drive shaft, and further drive the blade to rotate in the first rotation direction through the drive shaft, so as to realize the cutting of the hair at the first end by the blade.
[0036] By configuring the first cutting component as a combination of a drive shaft and a blade, the structure of the first cutting component can be simplified, the assembly efficiency of the first cutting component can be improved, and the manufacturing cost of the first cutting component can be reduced, while ensuring that the first cutting component can cut hair. This simplifies the structure of the cleaning equipment and improves the assembly efficiency of the cleaning equipment.
[0037] In one possible implementation, the cutting edge is an arc-shaped edge that bends away from the drive shaft;
[0038] Along the radial direction of the drive shaft, the apex of the arc-shaped blade is used to cut the hair on the first end.
[0039] In this way, by setting the blade edge to be an arc-shaped blade that bends away from the drive shaft, and making the apex of the arc-shaped blade cut the hair on the first end in the radial direction along the drive shaft, the contact area between the blade and the surface of the first end can be reduced, thereby reducing the contact resistance between the blade and the hair, making it easier to reduce the cutting resistance of the blade on the hair, and improving the cutting efficiency of the first cutting assembly on the hair at the first end.
[0040] In one possible implementation, the blade extends in a first direction, which intersects the axial direction of the drive shaft, and the axial direction of the drive shaft is the same as the axial direction of the first roller brush.
[0041] With the axis of the drive shaft aligned with the axis of the first roller brush, by making the extension direction of the blade intersect the axis of the drive shaft, the contact area between the blade and the surface of the first end can be reduced, as can the contact area with the hair wrapped around the first end. This reduces the line contact between the blade and the hair to almost point contact, thereby reducing the cutting resistance of the blade when cutting hair and improving the cutting efficiency of the first cutting assembly.
[0042] In one possible implementation, the blades are multiple and arranged circumferentially along the drive shaft.
[0043] In this way, by setting multiple blades on the drive shaft, the number of cuts made by the first cutting component on the hair wrapped around the first end can be increased, thereby improving the cutting efficiency of the hair and the working stability of the roller brush device.
[0044] In one possible implementation, each pair of adjacent blades is spaced apart;
[0045] Alternatively, at least some of the adjacent blades are arranged in an intersecting pattern;
[0046] Alternatively, along the extension direction of the blade, at least one end of two adjacent blades is connected.
[0047] In this way, by spacing adjacent blades apart, it is possible to reduce the number of blades on the drive shaft while ensuring that blades are evenly distributed around the drive shaft and maintaining cutting efficiency, and to reduce the manufacturing cost of the roller brush device.
[0048] In one possible implementation, along the axial direction of the drive shaft, the vertices of the arcuate cutting edges of each blade are located on the same circumference.
[0049] In this way, by ensuring that the apex of the curved edge of all the blades is located on the same circumference, it can be guaranteed that the apex of the curved edge of each blade can cut the hair on the first end, thereby improving the cutting efficiency of the first cutting assembly.
[0050] In one possible implementation, two adjacent blades do not overlap along the axial direction of the drive shaft;
[0051] In this way, while ensuring that multiple blades are arranged circumferentially on the drive shaft and that the cutting efficiency of the hair is guaranteed, the spacing between two adjacent blades can be appropriately widened, which can reduce the number of blades installed, thereby reducing the manufacturing cost of the first cutting component and the manufacturing cost of the roller brush device.
[0052] Alternatively, along the axial direction of the drive shaft, two adjacent blades may partially overlap.
[0053] If the extension direction of the blade intersects the axial direction of the drive shaft, then by partially overlapping two adjacent blades on the drive shaft, the distance between the two adjacent blades is relatively close, thereby increasing the number of blades installed on the drive shaft, which in turn increases the number of cuts on the hair wrapped around the first end and improves the cutting efficiency of the first cutting assembly.
[0054] In one possible implementation, a mounting cover is also included, which is disposed on at least a portion of the first cutting component.
[0055] In this way, by providing a mounting cover and placing the mounting cover over at least part of the first cutting component, the roller brush device can prevent the first cutting component from colliding with the roller brush device or other structures within the cleaning equipment during operation, thus avoiding damage to the first cutting component or other parts.
[0056] By installing at least a portion of the first cutting component inside the mounting cover, the likelihood of the user being cut by the first cutting component when disassembling or assembling the first cutting component or other components in the roller brush device can be reduced.
[0057] In one possible implementation, the roller brush device further includes:
[0058] The second transmission component rotates under the drive of the first roller brush;
[0059] The second cutting component is connected to the second transmission component. The second cutting component rotates along the first rotation direction under the drive of the second transmission component. The second cutting component is used to cut the hair wrapped around the second end during the rotation.
[0060] The second cutting component and the first roller brush are configured to have a speed difference when they rotate under the drive of the driving component.
[0061] In this way, by setting a second cutting component at the second end of the first roller brush, the hair wrapped around the second end of the first roller brush can be cut by the second cutting component, which can further improve the cutting effect of the hair at both ends of the first roller brush, thereby reducing the probability of the first roller brush getting tangled and stuck during use, improving the working stability of the first roller brush, and improving the working stability of the roller brush device.
[0062] By setting a second transmission component and enabling the first roller brush to drive the second cutting component to rotate through the second transmission component, the linkage between the first roller brush and the second cutting component can be realized, which can avoid the independent rotation between the second cutting component and the first roller brush, simplify the drive structure, reduce the space occupied by the roller brush device, simplify the driving process of the second cutting component and the first roller brush, and reduce manufacturing costs.
[0063] In addition, the first roller brush and the second cutting component are connected by a second transmission component, which can ensure the consistency of the first roller brush and the second cutting component during rotation and improve the working efficiency of the roller brush device.
[0064] In addition, by creating a speed difference between the second cutting component and the first roller brush when they rotate under the drive of the drive component, the relative rotation speed of the second cutting component and the first roller brush at the cutting position can be increased. This helps to improve the efficiency of the second cutting component in cutting the hair wrapped around the second end of the first roller brush, further preventing the first roller brush and the roller brush device from being entangled by hair, and improving the working stability of the cleaning equipment.
[0065] In one possible implementation, the roller brush device further includes a second roller brush, the second roller brush having a third end and a fourth end opposite each other in the axial direction; the second roller brush rotates in a second rotation direction under the drive of the drive assembly, the second rotation direction being opposite to the first rotation direction;
[0066] The axial direction of the first roller brush is parallel to the axial direction of the second roller brush.
[0067] In this way, the roller brush device is equipped with a second roller brush, the axis of which is parallel to the axis of the first roller brush, and there is a gap between the first and second roller brushes. The second roller brush rotates in the opposite direction to the first roller brush, so that both roller brushes can roll debris from the ground into the roller brush device at the gap, thereby cleaning the ground and improving the cleaning effect of the roller brush device.
[0068] In one possible implementation, the roller brush device further includes:
[0069] The third transmission component rotates under the drive of the second roller brush;
[0070] The third cutting component is connected to the third transmission component. The third cutting component rotates in the second rotation direction under the drive of the third transmission component. The third cutting component is used to cut the hair wrapped around the third end. The third cutting component and the second roller brush are configured to have a speed difference when they rotate under the drive of the driving component.
[0071] In this way, the roller brush device drives the third cutting component and the second roller brush to rotate in the second rotation direction by using the drive component of the cleaning equipment. This allows the third cutting component and the second roller brush to rotate relative to each other at the cutting position between them. This facilitates the third cutting component to cut the hair at the third end of the second roller brush, thereby preventing the third end of the second roller brush from getting stuck due to hair entanglement and ensuring the working stability of the cleaning equipment.
[0072] By setting a third transmission component and enabling the second roller brush to drive the third cutting component to rotate through the third transmission component, the linkage between the second roller brush and the third cutting component can be realized. This avoids independent rotation between the third cutting component and the second roller brush, simplifies the drive structure, reduces the space occupied by the roller brush device, simplifies the driving process of the third cutting component and the second roller brush, and reduces manufacturing costs.
[0073] In addition, the second roller brush and the third cutting component are connected by a third transmission component, which ensures the consistency of the second roller brush and the third cutting component during rotation and improves the working efficiency of the roller brush device.
[0074] And / or, the roller brush device further includes: a fourth transmission assembly that rotates under the drive of the second roller brush;
[0075] The fourth cutting component is connected to the fourth transmission component. The fourth cutting component rotates in the second rotation direction under the drive of the fourth transmission component. The fourth cutting component is used to cut the hair wrapped around the fourth end. The fourth cutting component and the second roller brush are configured to have a speed difference when they rotate under the drive of the driving component.
[0076] By setting a fourth cutting component at the fourth end of the second roller brush, the hair wrapped around the fourth end of the second roller brush can be cut by the fourth cutting component, which can further improve the cutting effect of the hair at both ends of the second roller brush. This reduces the probability of the second roller brush getting tangled and stuck during use, improves the working stability of the second roller brush, and improves the working stability of the roller brush device.
[0077] By setting a fourth transmission component and enabling the second roller brush to drive the fourth cutting component to rotate through the fourth transmission component, the linkage between the second roller brush and the fourth cutting component can be realized, which can avoid the independent rotation between the fourth cutting component and the second roller brush, simplify the drive structure, reduce the space occupation of the roller brush device, simplify the driving process of the fourth cutting component and the second roller brush, and reduce manufacturing costs.
[0078] In addition, by connecting the second roller brush and the fourth cutting component through the fourth transmission assembly, the consistency of the second roller brush and the fourth cutting component during rotation can be ensured, thereby improving the working efficiency of the roller brush device.
[0079] By creating a speed difference between the fourth cutting component and the second roller brush when they rotate under the drive of the drive component, the relative rotation speed of the fourth cutting component and the second roller brush at the cutting position can be increased. This helps to improve the efficiency of the fourth cutting component in cutting the hair wrapped around the fourth end of the second roller brush, further preventing the second roller brush and the roller brush device from being entangled by hair, and improving the working stability of the cleaning equipment.
[0080] A second aspect of this application provides a cleaning device, including a drive assembly and a roller brush device as described above;
[0081] The driving component is used to drive the first cutting component and the first roller brush of the roller brush device to rotate along the first rotation direction;

[0083] The cleaning equipment provided in this application, by using the aforementioned roller brush device, can improve the working stability of the cleaning equipment and reduce the probability of the cleaning equipment getting stuck due to hair entanglement during the cleaning process, thereby improving the practicality of the cleaning equipment.

Detailed Implementation
[0094] As described in the background section, in the cleaning equipment of the related art, the roller brush is easily entangled and jammed by hair during the cleaning process, which prevents it from working properly and affects the working stability of the cleaning equipment.
[0095] The reason for this problem is that the roller brush device in the existing cleaning equipment includes two roller brushes arranged side by side with a gap between them. When the roller brushes rotate, they will roll the debris on the ground into the interior of the cleaning equipment through the gap between the two roller brushes to clean the ground.
[0096] The two ends of the roller brush shaft are connected to the drive unit. Driven by the drive unit, the roller brush rotates. However, during use, hair on the ground will get caught in the two ends of the roller brush shaft. Since the hair at the two ends of the roller brush is not cleaned in time, more and more hair will be wrapped around the two ends, eventually causing the roller brush to be stuck by hair and unable to rotate. This will cause the roller brush device to malfunction and affect the working stability of the cleaning equipment.
[0097] To address the aforementioned technical problems, this application provides a roller brush device, a cleaning device, and a cleaning system for a cleaning equipment. The roller brush device uses a driving component of the cleaning equipment to drive a first cutting component and a first roller brush to rotate along a first rotation direction. This allows the first cutting component and the first roller brush to rotate relative to each other at positions close to each other, facilitating the first cutting component to cut the hair at the first end of the first roller brush. This prevents the first end of the first roller brush from becoming stuck due to hair entanglement and thus ensures the operational stability of the cleaning equipment.
[0098] In addition, by creating a speed difference between the first cutting component and the first roller brush when they rotate under the drive of the drive component, the relative rotation speed of the first cutting component and the first roller brush at the cutting position can be increased, thereby helping to improve the efficiency of the first cutting component in cutting the hair wrapped around the first end of the first roller brush, further preventing the first roller brush from being entangled by hair, and improving the working stability of the cleaning equipment.
[0099] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0100] Referring to Figures 1 to 4, this application embodiment provides a roller brush device 11 for a cleaning device 10, which can be a self-moving cleaning device, such as a sweeping robot or a robotic vacuum cleaner. The roller brush device 11 may include a first roller brush 100 and a first cutting component 200.
[0101] The first roller brush 100 may include a first end 110 and a second end 120 opposite each other in the axial direction, and the first end 110 and the second end 120 are rotatably connected to the bottom shell 13 of the cleaning device 10.
[0102] The first cutting component 200 and the first roller brush 100 rotate along a first rotation direction (direction M in FIG3) under the drive of the drive component 12 of the cleaning device 10. The first cutting component 200 is used to cut the hair wrapped around the first end 110 during the rotation.
[0103] This application provides a roller brush device 11. The roller brush device 11 uses the driving component 12 of the cleaning device 10 to drive the first cutting component 200 and the first roller brush 100 to rotate in a first rotation direction. This allows the first cutting component 200 and the first roller brush 100 to rotate relative to each other at the cutting position where they are close to each other. This facilitates the first cutting component 200 to cut the hair at the first end 110 of the first roller brush 100, thereby preventing the first end 110 of the first roller brush 100 from being stuck due to hair entanglement and unable to rotate normally, and ensuring the working stability of the cleaning device 10.
[0104] In some embodiments, the drive assembly 12 may have two independent drive members, and the first cutting assembly 200 and the first roller brush 100 are driven to rotate independently through one of the drive members, which can improve the control accuracy of the first roller brush 100 and the first cutting assembly 200.
[0105] Alternatively, the drive assembly 12 may have a single drive unit so that the first roller brush 100 and the first cutting assembly 200 are driven by a single drive unit, which can reduce the number of parts and simplify the structure.
[0106] In some implementations, the first cutting component 200 and the first roller brush 100 are configured to have a speed difference when they rotate under the drive of the drive component 12.
[0107] When the first cutting component 200 and the first roller brush 100 are driven by two independent driving components in the driving component 12, the rotational speed of the first cutting component 200 and the rotational speed of the first roller brush 100 can be adjusted independently to improve the adjustment accuracy of the rotational speed.
[0108] If the first cutting component 200 and the first roller brush 100 are driven simultaneously by the same driving component in the driving component 12, the first cutting component 200 and the first roller brush 100 can be connected by a speed reduction component so that there is a speed difference between the first cutting component 200 and the first roller brush 100 when they rotate.
[0109] In this way, by creating a speed difference between the first cutting component 200 and the first roller brush 100 when they rotate under the drive of the drive component 12, the relative rotation speed of the first cutting component 200 and the first roller brush 100 at the cutting position can be increased. This helps to improve the efficiency of the first cutting component 200 in cutting the hair wrapped around the first end 110 of the first roller brush 100, further preventing the first roller brush 100 from being entangled by hair, and improving the working stability of the cleaning device 10.
[0110] Referring to Figures 3 and 4, in some embodiments, if the first roller brush 100 and the first cutting component 200 are driven by the same driving member in the driving component 12, the roller brush device 11 may further include a first transmission component 300, which rotates under the drive of the first roller brush 100.
[0111] The first cutting component 200 is connected to the first transmission component 300, and the first cutting component 200 rotates in a first rotation direction under the drive of the first transmission component 300. By using the first transmission component 300 to connect the first roller brush 100 and the first cutting component 200, the first transmission component 300 enables the rotational speed of the first cutting component 200 to be less than the rotational speed of the first roller brush 100 device 11, thereby creating a speed difference between the first roller brush 100 and the first cutting component 200.
[0112] The first transmission component 300 can be a reduction gearbox, which can achieve a deceleration effect through gear transmission.
[0113] In this way, by using the first transmission component 300, the roller brush device 11 enables the first roller brush 100 to drive the first cutting component 200 to rotate in the first rotation direction, thereby realizing the linkage between the first roller brush 100 and the first cutting component 200. This avoids independent rotation between the first cutting component 200 and the first roller brush 100, simplifies the drive structure, reduces the space occupied by the roller brush device 11, simplifies the driving process of the first cutting component 200 and the first roller brush 100, and reduces manufacturing costs.
[0114] In addition, the first roller brush 100 and the first cutting component 200 are connected by the first transmission component 300, which can ensure the consistency of the first roller brush 100 and the first cutting component 200 during rotation and improve the working efficiency of the roller brush device 11.
[0115] Referring to Figures 3 and 4, in some embodiments, the first transmission component 300 may be a gear transmission component, which may include a drive gear 310, a trapezoidal gear 320, and an output gear 330.
[0116] The drive gear 310 is disposed at the first end 110 of the first roller brush 100, and the drive gear 310 rotates in the first rotation direction under the drive of the first roller brush 100. The drive gear 310 can be fixedly connected to the first end 110 of the first roller brush 100, or the drive gear 310 can be detachably connected to the first end 110 of the first roller brush 100.
[0117] The trapezoidal gear 320 meshes with the driving gear 310 and rotates along the second rotation direction under the drive of the driving gear 310. The first rotation direction and the second rotation direction (as shown in direction N in Figure 4) are opposite.
[0118] The output gear 330 meshes with the trapezoidal gear 320. The output gear 330 is disposed on the first cutting assembly 200 and is used to drive the first cutting assembly 200 to rotate in the first rotation direction.
[0119] In some embodiments, the output gear 330 can be fixedly connected to the first cutting assembly 200, or the output gear 330 can be detachably connected to the first cutting assembly 200.
[0120] 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 may be the same.
[0121] In this way, by using the meshing transmission between the drive gear 310, the trapezoidal gear 320 and the output gear 330, the first transmission component 300 enables the first cutting component 200 to rotate along the first rotation direction with the first roller brush 100 under the action of the first transmission component 300, so that the rotation directions of the first cutting component 200 and the first roller brush are opposite at the cutting position.
[0122] In addition, the meshing method between the drive gear 310, trapezoidal gear 320 and output gear 330 can realize the linkage between the first cutting component 200 and the first roller brush 100 with fewer parts, which facilitates the assembly of the roller brush device 11, reduces the manufacturing cost of the roller brush device 11, improves the assembly efficiency of the roller brush device 11, and can reduce the manufacturing cost of the cleaning equipment 10.
[0123] Referring to Figures 3 and 4, in some embodiments, the trapezoidal gear 320 may include a first tooth 321 and a second tooth 322, which are coaxially arranged and arranged along the axial direction of the trapezoidal gear 320. The first tooth 321 and the second tooth 322 are relatively fixed. By using the trapezoidal gear 320, the number of components in the first transmission assembly 300 can be retrieved, improving the assembly efficiency of the roller brush device 11.
[0124] The first tooth 321 meshes with the drive gear 310, and the outer diameter of the first tooth 321 is larger than the outer diameter of the drive gear 310. The second tooth 322 is coaxially arranged with the first tooth 321, and the second tooth 322 rotates under the drive of the first tooth 321, and the outer diameter of the second tooth 322 is smaller than the outer diameter of the first tooth 321.
[0125] In this way, by making the outer diameter of the first tooth 321 on the trapezoidal gear 320 larger than the outer diameter of the driving gear 310, the gear ratio between the first tooth 321 and the driving gear 310 can be increased, reducing the rotational speed of the first roller brush 100 transmitted from the driving gear 310 to the first tooth 321. This allows the rotational speed of the first cutting assembly 200 to decrease relative to the rotational speed of the first roller brush 100 after being transmitted through the first transmission assembly 300, thereby making the rotational speed of the first cutting assembly 200 lower than that of the first roller brush 100. Furthermore, since the first cutting assembly 200 and the first roller brush 100 move in opposite directions at the cutting point, the relative rotational speed between the first cutting assembly 200 and the first roller brush 100 can be further increased, further improving the cutting efficiency of the hair at the first end 110 of the first roller brush 100.
[0126] In addition, since the rotational speed decreases when passing through the first transmission component 300, the torque transmitted to the first cutting component 200 through the first transmission component 300 will increase accordingly. This allows the first cutting component 200 to overcome greater cutting resistance and improve its ability to cut hair, based on increasing the relative speed between the first cutting component 200 and the first roller brush 100.
[0127] By making the outer diameter of the second tooth 322 smaller than the outer diameter of the first tooth 321, the volume of the second tooth 322 can be reduced while maintaining the same rotational speed, which also helps to reduce the space occupied by the trapezoidal gear 320.
[0128] Referring to Figures 3 and 4, in some embodiments, the outer diameter of the output gear 330 is larger than the outer diameter of the second tooth 322.
[0129] In this way, by making the outer diameter of the output gear 330 larger than the outer diameter of the second tooth 322, the gear ratio can be further increased, the rotational speed transmitted from the first transmission assembly 300 to the first cutting assembly 200 can be further reduced, the torque transmitted from 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 roller 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 wrapped around the first end 110.
[0130] Referring to Figures 5 and 6, in some embodiments, the first cutting assembly 200 may include a drive shaft 210 and a blade 220.
[0131] The drive shaft 210 is connected to the first transmission assembly 300 and is used to rotate around a first rotation direction under the drive of the first transmission assembly 300. If the first transmission assembly 300 has an output gear 330, the output gear 330 can be disposed on the drive shaft 210. The axial direction of the drive shaft 210 is the same as the axial direction of the first roller brush 100.
[0132] A blade 220 is mounted on the drive shaft 210, with its cutting edge 221 facing the outer surface of the first end portion 110. The cutting edge 221 is used to cut the hair wrapped around the first end portion 110. There may be one or more blades 220; the more blades 220 there are, the more effective it is at cutting the hair wrapped around the first end portion 110. Cutting the hair on the first end portion 110 with the blade 220, due to the sharpness of the cutting edge 221, helps to cut the hair wrapped around the first end portion 110, thus improving cutting efficiency.
[0133] In this way, the drive shaft 210 of the first cutting component 200 is connected to the first transmission component 300 so that the first transmission component 300 transmits power to the drive shaft 210 and further drives the blade 220 to rotate in the first rotation direction through the drive shaft 210, so as to realize the cutting of the hair at the first end 110 by the blade 220.
[0134] By configuring the first cutting component 200 to cooperate with the drive shaft 210 and the blade 220, the structure of the first cutting component 200 can be simplified, the assembly efficiency of the first cutting component 200 can be improved, and the manufacturing cost of the first cutting component 200 can be reduced while ensuring that the first cutting component 200 can cut the hair. This simplifies the structure of the cleaning equipment 10 and improves the assembly efficiency of the cleaning equipment 10.
[0135] In other embodiments, the first cutting component 200 may also include a plurality of blades disposed on a drive shaft 210, which drives the blades to rotate, thereby cutting the hair wrapped around the first end 110.
[0136] Referring to Figures 5 and 6, in some embodiments, the blade 221 is an arc-shaped blade curved away from the drive shaft 210. Along the radial direction of the drive shaft 210, the apex of the arc-shaped blade is used to cut hair on the first end 110.
[0137] In this way, by setting the cutting edge 221 of the blade 220 to be an arc-shaped blade that bends away from the drive shaft 210, and by having the apex of the arc-shaped blade cut the hair on the first end 110 in the radial direction along the drive shaft 210, the contact area between the blade 220 and the surface of the first end 110 can be reduced, thereby reducing the contact resistance between the cutting edge 221 and the hair, which facilitates reducing the cutting resistance of the blade 220 on the hair and improving the cutting efficiency of the first cutting assembly 200 on the hair of the first end 110.
[0138] In some embodiments, the length extension direction of the blade 221 may be the same as the extension direction of the drive shaft 210.
[0139] Referring to Figures 5 and 6, in some other embodiments, the length extension direction of the blade 221 is a first direction (direction P in Figure 5), which intersects the axial direction of the drive shaft 210, and the axial direction of the drive shaft 210 is the same as the axial direction of the first roller brush 100.
[0140] In some embodiments, the length extension direction of the blade 221 may be perpendicular to the axial direction of the drive shaft 210.
[0141] With the axial direction of the drive shaft 210 being the same as that of the first roller brush 100, by making the extension direction of the blade 221 intersect the axial direction of the drive shaft 210, the contact area between the blade 221 and the surface of the first end 110 can be reduced, and the contact area with the hair wrapped around the first end 110 can be reduced, so that the contact between the blade 221 and the hair is reduced from line contact to almost point contact, thereby reducing the cutting resistance of the blade 220 when cutting hair and improving the cutting efficiency of the first cutting assembly 200.
[0142] Referring to Figures 5 and 6, in some embodiments, the blade 220 can be multiple, and the multiple blades 220 are arranged circumferentially along the drive shaft 210. Alternatively, the multiple blades 220 can be spaced apart and evenly arranged circumferentially along the drive shaft 210.
[0143] In this way, by setting multiple blades 220 on the drive shaft 210, the number of cuts made by the first cutting assembly 200 on the hair wrapped around the first end 110 can be increased, thereby improving the cutting efficiency of the hair and improving the working stability of the roller brush device 11.
[0144] Referring to Figures 5 and 6, in some embodiments, each pair of adjacent blades 220 can be spaced apart.
[0145] The two adjacent blades 220 can be spaced apart and evenly arranged, which facilitates the design and production of the first cutting assembly 200.
[0146] In other embodiments, at least some adjacent blades 220 may be arranged in an intersecting manner. Alternatively, at least one end of two adjacent blades 220 may be connected along the extension direction of the blades 220.
[0147] In this way, by setting two adjacent blades 220 at intervals, it is possible to reduce the number of blades 220 set on the drive shaft 210 while ensuring that the blades 220 are set in the circumference of the drive shaft 210 and the cutting efficiency is guaranteed, and to reduce the manufacturing cost of the roller brush device 11.
[0148] Referring to Figures 5 and 6, in some embodiments, if the cutting edge 221 of each blade 220 is an arc-shaped edge, then along the axial direction of the transmission shaft 210, the apex of the arc-shaped edge of each blade 220 can be located on the same circumference (circumference Q in Figure 6).
[0149] In this way, by making the apex of the arc-shaped blades of all the blades 220 lie on the same circumference, it can be ensured that the apex of the arc-shaped blade of each blade 220 can cut the hair on the first end 110, thereby improving the cutting efficiency of the first cutting assembly 200.
[0150] Referring to Figures 5 and 6, in some embodiments, two adjacent blades 220 do not overlap along the axial direction of the drive shaft 210. It should be noted that, "two adjacent blades 220 do not overlap along the axial direction of the drive shaft 210" means that the orthographic projections of two adjacent blades 220 do not overlap along the axial direction of the drive shaft 210.
[0151] In this way, while ensuring that multiple blades 220 are arranged circumferentially on the drive shaft 210 and ensuring the cutting efficiency of hair, the spacing between two adjacent blades 220 can be appropriately widened, thereby reducing the number of blades 220 installed, which can reduce the manufacturing cost of the first cutting assembly 200 and the manufacturing cost of the roller brush device 11.
[0152] Referring to Figure 6, along the axial direction of the drive shaft 210, two adjacent blades 220 partially overlap. It should be noted that "two adjacent blades 220 partially overlap" along the axial direction of the drive shaft 210 means that the orthographic projections of two adjacent blades 220 overlap along the axial direction of the drive shaft 210.
[0153] If the extension direction of the blade 221 intersects the axial direction of the drive shaft 210, then by partially overlapping two adjacent blades 220 on the drive shaft 210, the distance between the two adjacent blades 220 is relatively close, thereby increasing the number of blades 220 installed on the drive shaft 210, thereby increasing the number of cuts on the hair wrapped around the first end 110 and improving the cutting efficiency of the first cutting assembly 200.
[0154] Referring to FIG2, in some embodiments, the roller brush device 11 may further include a mounting cover 400, which covers at least a portion of the first cutting assembly 200.
[0155] In this way, by providing a mounting cover 400 and covering at least part of the first cutting component 200, the roller brush device 11 can prevent the first cutting component 200 from colliding with the roller brush device 11 or other structures in the cleaning equipment 10 during operation, thus avoiding damage to the first cutting component 200 or other parts.
[0156] By mounting at least a portion of the first cutting assembly 200 inside the mounting cover 400, the likelihood of a user being cut by the first cutting assembly 200 when disassembling or assembling the first cutting assembly 200 or other components in the roller brush device 11 can be reduced.
[0157] Referring to Figure 4, in some embodiments, if the first cutting assembly 200 has a blade 220 and a drive shaft 210, then the mounting cover 400 can cover the blade 220 and allow the drive shaft 210 to pass through. The drive shaft 210 can rotate relative to the mounting cover 400, and the drive shaft 210 can drive the blade 220 inside the mounting cover 400 to rotate. By providing the mounting cover 400, it is possible to prevent operators from being cut by the blade 220 when assembling or disassembling the roller brush device 11.
[0158] In addition, since the drive shaft 210 passes through the mounting cover 400, the mounting cover 400 can also limit the displacement of the drive shaft 210. For example, when the drive shaft 210 passes through the mounting cover 400, the mounting cover 400 can limit the drive shaft 210 to move in the axial direction and rotate around the axial direction, preventing the drive shaft 210 from deviating relative to the axial direction, improving the stability of the drive shaft 210 during rotation, and thus improving the working stability of the first cutting assembly 200.
[0159] Referring to Figures 2 and 3, in some embodiments, the roller brush device 11 may 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 tractively connected to the second transmission assembly 500a and rotates in a first rotation direction under the drive of the second transmission assembly 500a. The second cutting assembly 500b is used to cut hair wrapped around the second end 120 during rotation. The second cutting assembly 500b and the first roller brush 100 are configured to have a speed difference when rotating under the drive of the drive assembly 12.
[0160] In some embodiments, the specific structures of the second transmission component 500a and the first transmission component 300 and their cooperation with other components may be the same, and the structures of the second cutting component 500b and the first cutting component 200 and their cooperation with other components may be the same. Here, the second transmission component 500a and the second cutting component 500b will not be elaborated on in detail.
[0161] In this way, by providing a second cutting component 500b at the second end 120 of the first roller brush 100, the hair wrapped around the second end 120 of the first roller brush 100 can be cut by the second cutting component 500b, which can further improve the cutting effect on the hair at both ends of the first roller brush 100, thereby reducing the probability of the first roller brush 100 being entangled and stuck by hair during use, improving the working stability of the first roller brush 100, and improving the working stability of the roller brush device 11.
[0162] By setting a second transmission component 500a and causing the first roller brush 100 to drive the second cutting component 500b to rotate via the second transmission component 500a, the linkage between the first roller brush 100 and the second cutting component 500b can be realized. This avoids independent rotation between the second cutting component 500b and the first roller brush 100, simplifies the drive structure, reduces the space occupied by the roller brush device 11, simplifies the driving process of the second cutting component 500b and the first roller brush 100, and reduces manufacturing costs.
[0163] In addition, the first roller brush 100 and the second cutting component 500b are connected by the second transmission component 500a, which can ensure the consistency of the first roller brush 100 and the second cutting component 500b during rotation and improve the working efficiency of the roller brush device 11.
[0164] In addition, by creating a speed difference between the second cutting component 500b and the first roller brush 100 when they rotate under the drive of the drive component 12, the relative rotation speed of the second cutting component 500b and the first roller brush 100 at the cutting position can be increased. This helps to improve the efficiency of the second cutting component 500b in cutting the hair wrapped around the second end 120 of the first roller brush 100, further preventing the first roller brush 100 and the roller brush device 11 from being entangled by hair, and improving the working stability of the cleaning device 10.
[0165] Referring to Figures 4 and 5, in some embodiments, the roller brush device 11 may further include a second roller brush 800, which may include a third end 810 and a fourth end 820 opposite to each other in the axial direction. The second roller brush 800 rotates in a second rotation direction (the N direction in Figure 4) under the drive of the drive 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.
[0166] In this way, the roller brush device 11 is equipped with a second roller brush 800, the axis of which is parallel to the axis of the first roller brush 100 and the second roller brush 800, and there is a gap between them. The second roller brush 800 and the first roller brush 100 rotate in opposite directions, so that both roller brushes can roll debris from the ground into the roller brush device 11 at the gap, thereby cleaning the ground and improving the cleaning effect of the roller brush device 11.
[0167] Referring to Figures 2 and 3, in some embodiments, the roller brush device 11 may further include a third transmission component 600a and a third cutting component 600b. The third transmission component 600a rotates under the drive of the second roller brush 800. The third cutting component 600b is drively connected to the third transmission component 600a and rotates in a second rotation direction under the drive of the third transmission component 600a. The third cutting component 600b is used to cut hair wrapped around the third end 810. The third cutting component 600b and the second roller brush 800 are configured to have a speed difference when rotating under the drive of the drive component 12.
[0168] In some embodiments, the structure of the third transmission component 600a and the first transmission component 300 and their cooperation with other components may be the same, and the structure of the third cutting component 600b and the first cutting component 200 and their cooperation with other components may be the same. Here, the third transmission component 600a and the third cutting component 600b will not be elaborated on in detail.
[0169] In this way, the roller brush device 11 drives the third cutting component 600b and the second roller brush 800 to rotate in the second rotation direction by using the drive component 12 of the cleaning device 10. This allows the third cutting component 600b and the second roller brush 800 to rotate relative to each other at the cutting position between them. This facilitates the third cutting component 600b cutting the hair at the third end 810 of the second roller brush 800, thus preventing the third end 810 of the second roller brush 800 from getting stuck due to hair entanglement and ensuring the working stability of the cleaning device 10.
[0170] By setting a third transmission component 600a and causing the second roller brush 800 to drive the third cutting component 600b to rotate via the third transmission component 600a, the linkage between the second roller brush 800 and the third cutting component 600b can be realized. This avoids independent rotation between the third cutting component 600b and the second roller brush 800, simplifies the drive structure, reduces the space occupied by the roller brush device 11, simplifies the driving process of the third cutting component 600b and the second roller brush 800, and reduces manufacturing costs.
[0171] In addition, the second roller brush 800 and the third cutting component 600b are connected by the third transmission component 600a, which can ensure the consistency of the second roller brush 800 and the third cutting component 600b during rotation and improve the working efficiency of the roller brush device 11.
[0172] Referring to Figures 2 and 3, in some embodiments, the roller brush device 11 may further include a fourth transmission assembly 700a and a fourth cutting assembly 700b. The fourth transmission assembly 700a rotates under the drive of the second roller brush 800. The fourth cutting assembly 700b is driveably connected to the fourth transmission assembly 700a and rotates in a second rotation direction under the drive of the fourth transmission assembly 700a. The fourth cutting assembly 700b is used to cut hair wrapped around the fourth end 820. The fourth cutting assembly 700b and the second roller brush 800 are configured to have a speed difference when rotating under the drive of the drive assembly 12.
[0173] In some embodiments, the structures of the fourth transmission component 700a and the first transmission component 300 and their cooperation with other components may be the same, and the structures of the fourth cutting component 700b and the first cutting component 200 and their cooperation with other components may be the same. Here, the fourth transmission component 700a and the fourth cutting component 700b will not be elaborated on in detail.
[0174] By providing a fourth cutting component 700b at the fourth end 820 of the second roller brush 800, the hair wrapped around the fourth end 820 of the second roller brush 800 can be cut by the fourth cutting component 700b, which can further improve the cutting effect on the hair at both ends of the second roller brush 800, thereby reducing the probability of the second roller brush 800 being entangled and stuck by hair during use, improving the working stability of the second roller brush 800, and improving the working stability of the roller brush device 11.
[0175] By setting a fourth transmission component 700a and causing the second roller brush 800 to drive the fourth cutting component 700b to rotate via the fourth transmission component 700a, the linkage between the second roller brush 800 and the fourth cutting component 700b can be realized. This avoids independent rotation between the fourth cutting component 700b and the second roller brush 800, simplifies the drive structure, reduces the space occupied by the roller brush device 11, simplifies the driving process of the fourth cutting component 700b and the second roller brush 800, and reduces manufacturing costs.
[0176] In addition, by connecting the second roller brush 800 and the fourth cutting component 700b via the fourth transmission component 700a, the consistency of the second roller brush 800 and the fourth cutting component 700b during rotation can be ensured, thereby improving the working efficiency of the roller brush device 11.
[0177] By creating a speed difference between the fourth cutting component 700b and the second roller brush 800 when they rotate under the drive of the drive component 12, the relative rotation speed of the fourth cutting component 700b and the second roller brush 800 at the cutting position can be increased. This helps to improve the efficiency of the fourth cutting component 700b in cutting the hair wrapped around the fourth end 820 of the second roller brush 800, further preventing the second roller brush 800 and the roller brush device 11 from being entangled by hair, and improving the working stability of the cleaning device 10.
[0178] Referring to Figures 1 and 2, this application embodiment also provides a cleaning device 10, which can be a self-moving cleaning device 10.
[0179] The cleaning device 10 may include a drive assembly 12 and the aforementioned roller brush device 11. The drive assembly 12 is used to drive the first cutting assembly 200 and the first roller brush 100 of the roller brush device 11 to rotate in a first rotation direction;

[0181] The cleaning equipment 10 provided in this application, by using the aforementioned roller brush device 11, can improve the working stability of the cleaning equipment 10 and reduce the probability of the cleaning equipment 10 getting stuck due to the roller brush device 11 being tangled in hair during the cleaning process, thereby improving the practicality of the cleaning equipment 10.
