Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a cleaning device. Background Technology

[0002] Cleaning devices such as mite removers, vacuum cleaners, and robotic vacuum cleaners are commonly used in households. Vacuum cleaners and robotic vacuum cleaners can clean floors, while mite removers can remove dust and worms from surfaces such as mattresses and leather.

[0003] In related technologies, cleaning equipment typically includes a housing and a fan unit installed inside the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A roller brush can be installed at the position corresponding to the air inlet. The roller brush rolls on the surface to be cleaned, picking up dust and hair, and the suction from the air inlet draws the dust and hair into the equipment, thus achieving the cleaning function.

[0004] However, during the cleaning process, hair fibers tend to get tangled on the roller brush as it rotates, and then tighten towards the shafts at both ends of the brush, making cleaning difficult. Utility Model Content

[0005] This application provides a cleaning device to solve the technical problem that in current cleaning devices, hair fibers become entangled on the roller brush as it rotates and continuously tighten towards the rotating shafts at both ends of the roller brush during the cleaning process, making cleaning difficult.

[0006] This application provides a cleaning device, which includes a device body and two roller brush assemblies. The device body has a roller brush cavity, and the two roller brush assemblies are coaxially arranged in the roller brush cavity along a first direction. The roller brush cavity is provided with an air intake, which is opposite to the ends of the two roller brush assemblies that face each other.

[0007] Both roller brush assemblies include a roller and multiple flexible cleaning elements. The multiple flexible cleaning elements are spaced apart on the side wall of the roller, and each flexible cleaning element protrudes radially from the roller surface. At least one of the multiple flexible cleaning elements has a greater radial height along the roller at the end away from the air inlet than at the end near the air inlet.

[0008] The cleaning device provided in this application uses two coaxially arranged roller brush assemblies to perform simultaneous rolling cleaning within the roller brush cavity, with the air inlet positioned opposite to the two. During the cleaning process, the hair fibers rolled up on each roller brush assembly can slide from the higher end of the flexible cleaning component to the lower end, causing the hair fibers to move closer to the air inlet as the flexible cleaning component rotates. The hair fibers then detach from the air inlet at the end of the roller brush assembly closest to the air inlet and are sucked into the air inlet, thus preventing the fibers and hair from getting tangled on the roller brush assembly and improving the convenience of cleaning the roller brush assembly.

[0009] As an alternative implementation, at least one of the multiple flexible cleaning components gradually decreases in height along the radial direction of the roller from the end furthest from the air intake to the end closest to the air intake.

[0010] With this configuration, as the roller brush assembly rotates, fibers and hairs can quickly slide towards the air intake along the narrowing direction of the flexible cleaning component, improving the efficiency of fiber and hair being sucked in.

[0011] As an alternative implementation, at least one of the plurality of flexible cleaning elements maintains an equal height along the radial direction of the roller in a first direction.

[0012] This design ensures that at least one flexible cleaning component can contact the surface to be cleaned during the rolling process, guaranteeing a good cleaning effect.

[0013] As an alternative implementation, the diameter of the roller is equal at different positions along the first direction.

[0014] This configuration ensures that the mounting axis of the roller brush assembly is horizontal during roller assembly, improving the ease of roller installation.

[0015] As an alternative implementation, the sidewall of the roller is provided with a slot that extends from one end of the roller axially to the other end; the flexible cleaning element is inserted into the slot.

[0016] The roller has an abutment part at the end near the air inlet, and the flexible cleaning component abuts against the abutment part; the roller brush assembly may also include an end cap, which is connected to the end of the roller away from the air inlet and is positioned at the end of the flexible cleaning component.

[0017] This design improves the installation stability of the flexible cleaning component on the roller. When the flexible cleaning component deforms upon contact with the surface to be cleaned, the limiting at both ends prevents movement along the roller axis.

[0018] As an alternative implementation, there is a gap between the ends of the two roller brush assemblies facing each other, and the air inlet is positioned directly opposite the gap.

[0019] This setup creates an empty area directly in front of the air inlet, improving the efficiency of the clean airflow and providing greater negative pressure suction to draw the hair fibers picked up by the roller brush assembly into the device.

[0020] As an optional implementation, the gap size can be L, where 10mm≤L≤30mm.

[0021] This design avoids both situations where the gaps are too small, preventing fibers, hair, and debris from being sucked into the air intake, and where the gaps are too large, resulting in insufficient coverage of the roller brush assembly and affecting the cleaning effect.

[0022] As an alternative implementation, the cleaning device may also include a drive assembly configured to drive the two roller brush assemblies to rotate.

[0023] Each of the two roller brush assemblies includes a fixed end and a free end, with the free ends of the two roller brush assemblies facing each other and positioned close to the air intake; the drive assembly has two drive ends; the fixed ends of the two roller brush assemblies are located at both ends of the roller brush cavity along the first direction and are respectively connected to the two drive ends.

[0024] This setup allows for a reasonable layout of the drive components and makes full use of the space at the ends of the roller brush components, ensuring that both roller brush components can rotate smoothly for cleaning.

[0025] As an optional implementation, the drive assembly may include two drive units and two transmission mechanisms, with the two drive units respectively connected to the two transmission mechanisms, and the two transmission mechanisms respectively connected to the two roller brush assemblies.

[0026] The transmission mechanism includes a flexible transmission component and two transmission wheels. One of the two transmission wheels is connected to the drive unit, and the other of the two transmission wheels is coaxially connected to the fixed end of the drum. The flexible transmission component is wound around the two transmission wheels.

[0027] With this configuration, two drive units can drive the two roller brush assemblies separately, enabling independent control of the two roller brush assemblies and ensuring the stability and reliability of the drive structure.

[0028] As an optional implementation, the drive assembly may include a drive unit, a drive member, and two transmission mechanisms. The drive unit is configured to drive the drive member to rotate. The two ends of the drive member are respectively connected to the two transmission mechanisms, and the two transmission mechanisms are respectively connected to two roller brush assemblies.

[0029] The transmission mechanism includes a flexible transmission component and two transmission wheels. One of the two transmission wheels is coaxially connected to the driving component, and the other of the two transmission wheels is coaxially connected to the fixed end of the drum. The flexible transmission component is wound around the two transmission wheels.

[0030] This configuration allows two roller brush components to be driven synchronously by a single drive unit, simplifying the drive structure and reducing space requirements.

[0031] As an optional implementation, the roller brush assembly has a connecting hole coaxially arranged with its rotation axis, the connecting hole having an internal thread, and the connecting hole facing the corresponding transmission mechanism; the drive assembly may also include a connector, a transmission wheel coaxially connected to the fixed end of the roller is fixed to the connector, the connector is inserted into the connecting hole and threadedly screwed into the connecting hole.

[0032] This configuration ensures that the axis of the roller brush assembly and the drive wheel are collinear, preventing vibration during the rotation of the roller brush assembly.

[0033] This application provides a cleaning device comprising a main body and two roller brush assemblies. The main body has a roller brush cavity, and the two roller brush assemblies are coaxially disposed within the roller brush cavity along a first direction. An air intake is provided within the roller brush cavity, with the air intake facing the ends of the two roller brush assemblies. Each roller brush assembly includes a roller and multiple flexible cleaning elements. The multiple flexible cleaning elements are spaced apart on the side wall of the roller, and each flexible cleaning element protrudes radially from the roller surface. At least one of the multiple flexible cleaning elements has a greater radial height along the roller than the end closest to the air intake. Thus, during cleaning, hair fibers rolled up on each roller brush assembly can slide from the higher end of the flexible cleaning element to the lower end, allowing the hair fibers to rotate and approach the air intake. The hair fibers then detach from the air intake at the end of the roller brush assembly closest to the air intake and are drawn into the air intake, thereby preventing hair fibers from tangling on the roller brush assembly and improving the ease of cleaning the roller brush assembly.

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0053] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] Cleaning equipment typically includes a housing and a fan unit installed inside the housing. The airflow generated by the fan unit creates suction at the air inlet of the housing. A roller brush can be installed at the corresponding position of the air inlet. The roller brush rolls on the surface to be cleaned, picking up dust and hair, and the suction from the air inlet draws the dust and hair into the equipment, thus achieving the cleaning function.

[0056] However, during the cleaning process, hair easily gets tangled in the roller brush of current cleaning equipment and cannot be sucked into the device. Take mite removers as an example. Mite removers can remove dust and worms from the surfaces of mattresses, leather, etc. Mattresses usually have a lot of hair adhering to them. When the roller brush of the mite remover rolls over the mattress surface, the hair easily gets tangled in the roller brush. As the roller brush rolls, the tangled hair gets more and more tightly wrapped towards both ends of the roller brush and cannot be sucked away. This also makes cleaning the roller brush time-consuming and laborious.

[0057] To address the aforementioned technical problems, this application provides a cleaning device. This cleaning device utilizes the layout and structural design of the roller brush assembly to perform cleaning operations simultaneously using two roller brush assemblies. Furthermore, by designing the height difference of the flexible cleaning elements on the roller brush assemblies, the hair rolled up by the roller brush assemblies can be rolled and slid into the area between the two roller brush assemblies, thereby being sucked into the air intake and preventing hair fibers from becoming entangled on the roller brush assemblies and unable to be cleaned.

[0058] The following is an example illustrating the application scenarios of the cleaning equipment provided in the embodiments of this application.

[0059] The cleaning equipment provided in this application embodiment is a cleaning tool with a roller brush structure. Specifically, the product type of the cleaning equipment in this application embodiment may include, but is not limited to, mite removers, vacuum cleaners, sweeping machines, and robotic vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used to clean floors, clothes, bedding, sofas, furniture, etc. This application embodiment does not make any specific limitations on this.

[0060] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 This is a schematic diagram of the bottom side of the cleaning equipment provided in the embodiments of this application; Figure 3 This is a schematic diagram of the internal structure of the roller brush cavity of the cleaning device provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the roller brush assembly in the cleaning equipment provided in the embodiments of this application.

[0061] See Figures 1 to 4 As shown, this application provides a cleaning device 10, which includes a device body 100 and two roller brush assemblies 200. The device body 100 has a roller brush cavity 101, and the two roller brush assemblies 200 are coaxially disposed in the roller brush cavity 101 along a first direction.

[0062] When the cleaning device 10 is performing a cleaning operation, the side of the device body 100 connected to the roller brush assembly 200 faces the surface to be cleaned. The roller brush assembly 200 can contact the surface to be cleaned. As the device body 100 moves, the two roller brush assemblies 200 roll simultaneously on the surface to be cleaned. When the roller brush assembly 200 rolls, it can pick up dust, hair, and other debris on the surface to be cleaned, making it easier for the dust, hair, and other debris to be sucked into the device body 100.

[0063] In this embodiment, the roller brush cavity 101 is provided with an air intake 102, which is opposite to the ends of the two roller brush assemblies 200 that face each other. During the rotation cleaning process, dust, hair fibers, etc., rolled up from the surface to be cleaned by the roller brush assembly 200 are sucked into the main body 100 of the device through the air intake 102.

[0064] Both roller brush assemblies 200 include a roller 210 and a plurality of flexible cleaning elements 220. The plurality of flexible cleaning elements 220 are spaced apart on the side wall of the roller 210, and the flexible cleaning elements 220 protrude radially from the surface of the roller 210. At least one of the plurality of flexible cleaning elements 220 has a greater radial height along the roller 210 at the end away from the air intake 102 than at the end near the air intake 102.

[0065] It is understood that the two roller brush assemblies 200 can be arranged sequentially along the length of the roller brush cavity 101, with a gap between their ends. The air inlet 102 is opposite to the middle of the roller brush cavity 101, and the position of the air inlet 102 can correspond to the gap between the two roller brush assemblies 200.

[0066] Because there is a height difference between different positions of the flexible cleaning element 220 along the radial direction of the roller 210 on the roller brush assembly 200, the protrusion height of the flexible cleaning element 220 at the end closer to the suction port 102 is lower, while the protrusion height of the flexible cleaning element 220 at the end farther from the suction port 102 is higher. When the roller brush assembly 200 picks up hair fibers, as the roller brush assembly 200 rotates and the suction port 102 continuously generates suction, the hair fibers will slide from the higher position of the flexible cleaning element 220 to the lower position on the periphery of the roller brush assembly 200, and then be sucked into the suction port 102.

[0067] For example, two roller brush assemblies 200 are coaxially arranged, and their axes can be parallel to the length direction of the roller brush cavity 101. For instance, when the cleaning device 10 moves to clean on a horizontal plane, the axis of the roller brush assembly 200 is parallel to the horizontal direction.

[0068] For example, the two roller brush assemblies 200 can be symmetrically arranged relative to the cleaning device 10 along its central axis in the cleaning direction to ensure that the roller brush assemblies 200 are subjected to balanced force when they roll into contact with the surface to be cleaned at the same time, so as to avoid difficulty in controlling the cleaning device 10 when it is pushed to move back and forth.

[0069] It should be noted that in the cleaning device 10 provided in this application embodiment, two coaxially arranged roller brush assemblies 200 perform rolling cleaning simultaneously, and the air intake 102 is positioned relative to the two. During the cleaning process, the hair fibers rolled up on each roller brush assembly 200 can be gathered and slid from the higher end of the flexible cleaning member 220 to the lower end, so that the hair fibers move closer to the air intake 102 as the flexible cleaning member 220 rotates, and then detach from the roller brush assembly 200 at the end closest to the air intake and are sucked into the air intake 102. This prevents the hair fibers from getting tangled on the roller brush assembly 200 and improves the convenience of cleaning the roller brush assembly 200.

[0070] The axis of the roller brush assembly 200 is defined as the X direction, and there is a height difference between the two ends of the flexible cleaning component 220 along the X direction. The cleaning movement direction of the cleaning device 10 is the Y direction, which can be perpendicular to the X direction.

[0071] In this embodiment, the suction port 102 generates suction on the side of the roller brush assembly 200, drawing dust and hair carried up by the two roller brush assemblies 200 into the device body 100. The suction force at the position opposite to the suction port 102 is greater than at other positions not opposite to the suction port 102. Therefore, hair that moves around the suction port 102 along the direction of decreasing height of the flexible cleaning member 220 is more easily drawn into the suction port 102.

[0072] The following provides a detailed description of the specific structure of the flexible cleaning component 220 and the specific connection method between the flexible cleaning component 220 and the roller 210.

[0073] Figure 5 This is a schematic diagram of the structure of the roller of the roller brush assembly in the cleaning equipment provided in the embodiments of this application; Figure 6 This is an axial sectional view of the roller brush assembly in the cleaning equipment provided in the embodiments of this application; Figure 7 This is a radial cross-sectional view of the roller brush assembly in the cleaning device provided in an embodiment of this application.

[0074] like Figures 1 to 7 As shown, in one possible implementation, at least one of the multiple flexible cleaning elements 220 has a radial height that gradually decreases from the end furthest from the air intake 102 to the end closest to the air intake 102. Thus, the edge of the flexible cleaning element 220 furthest from the surface of the roller 210 is inclined relative to the axial direction of the roller 210.

[0075] Understandably, during the rotation of the roller brush assembly 200, the hair fibers wrap and tighten on the roller brush assembly 200. At this time, the edge of the flexible cleaning element 220 away from the surface of the roller 210 can guide the hair to slide towards the suction port 102, that is, quickly slide along the narrowing direction of the flexible cleaning element 220, thereby improving the efficiency of the fibers and hair being sucked in.

[0076] In this embodiment, the outer contour formed by the roller brush assembly 200 when rotating is a body of revolution, and the radial cross-section of the formed body of revolution is circular. The outer contour diameter of the roller brush assembly 200 refers to the diameter of the radial cross-section of the body of revolution formed when rotating about its axial direction. When the roller brush assembly 200 picks up hair, as the hair is rolled up, the hair will gather or slide towards a position with a smaller outer contour diameter of the roller brush assembly 200. That is, the picked-up hair will gather or move towards a position opposite to the air intake 102, thus making it easier to be sucked into the air intake 102.

[0077] In some embodiments, at least one of the plurality of flexible cleaning elements 220 maintains an equal height along the radial direction of the roller 210 in a first direction. The first direction is the X direction.

[0078] It is understandable that among the multiple flexible cleaning components 220, there are both flexible cleaning components 220 with gradually changing heights and flexible cleaning components 220 with varying heights, thereby ensuring that at least one flexible cleaning component 220 can contact the surface to be cleaned during the rolling process of the roller brush assembly 200, thus ensuring a good cleaning effect.

[0079] For example, the flexible cleaning element 220 can be one or a combination of adhesive strips, brushes, etc. For instance, the flexible cleaning element 220 can be an adhesive strip. When an adhesive is used as the flexible cleaning element 220, the adhesive strip can pat the surface to be cleaned, and hair will not get tangled on the adhesive strip. The hair carried by the adhesive strip is more easily sucked into the interior of the cleaning device 10 along the outer edge of the adhesive.

[0080] In some embodiments, the diameter of the roller 210 is equal at different positions along the first direction. This ensures that the mounting axis of the roller brush assembly 200 is horizontal during roller 210 assembly, improving the ease of roller 210 installation.

[0081] For example, the roller 210 can be a cylindrical structure, and the flexible cleaning component 220 protrudes from the surface of the roller 210 and has a height difference along the first direction. This can be achieved through the structure of the flexible cleaning component 220 itself, that is, the width dimension of the flexible cleaning component 220 is different at different positions along its length direction.

[0082] In some embodiments, the sidewall of the roller 210 is provided with a slot 211, which extends axially from one end of the roller 210 to the other end. A flexible cleaning element 220 is inserted into the slot 211.

[0083] The roller 210 has an abutment portion 212 at its end near the air intake 102, and the flexible cleaning component 220 abuts against the abutment portion 212. The roller brush assembly 200 may also include an end cap 230, which is connected to the end of the roller 210 away from the air intake 102 and abuts against the end of the flexible cleaning component 220. During assembly, the flexible cleaning component 220 can be inserted into the slot 211 from one end of the roller 210. After the flexible cleaning component 220 abuts against the abutment portion 212, the end cap 230 is then installed to abut against the end of the flexible cleaning component 220.

[0084] Understandably, the slot 211 can limit the flexible cleaning component 220 radially to the roller 210, and the abutment part 212 and the end cap 230 can limit the flexible cleaning component 220 axially to the roller 210 at both ends, thereby improving the installation stability of the flexible cleaning component 220 on the roller 210. When the flexible cleaning component 220 deforms upon contact with the surface to be cleaned, the limiting at both ends can prevent movement along the roller 210 axially.

[0085] For example, the end cap 230 may be circular in shape. The end cap 230 may be coaxially arranged with the roller 210, and the coverage area of ​​the end cap 230 is larger than the end area of ​​the roller 210, so as to prevent hair from being rolled into the rollers at both ends of the roller 210.

[0086] For example, multiple flexible cleaning elements 220 can be arranged in parallel and all extend along the axial direction of the roller 210. In this way, flexible cleaning elements 220 can contact the surface being cleaned along the axial direction of the roller brush assembly 200, thereby increasing the cleaning range.

[0087] For example, multiple flexible cleaning elements 220 extend spirally along the circumferential outer wall of the roller 210. In this way, as the roller brush assembly 200 rolls along the cleaning direction of the cleaning device 10, different positions of the flexible cleaning elements 220 in the extension direction can sequentially contact the surface to be cleaned as the roller brush assembly 200 rolls, without obstructing the negative pressure airflow of the suction port 102, thereby improving the suction efficiency of dust and hair.

[0088] It should be noted that the number of flexible cleaning components 220 can be two, three, four, five or more, and this application embodiment does not specifically limit this.

[0089] In some embodiments, the flexible cleaning member 220 has a snap-fit ​​protrusion on the side facing the axis of the roller 210, and the snap-fit ​​protrusion snaps into the slot 211.

[0090] It is understandable that the thickness of the snap-fit ​​protrusion is greater than the thickness of the part of the flexible cleaning component 220 that protrudes from the surface of the roller 210. The snap-fit ​​protrusion and the slot 211 cooperate to limit the flexible cleaning component 220 in the radial direction of the roller 210, ensuring the reliability of the installation of the flexible cleaning component 220 on the roller 210 and preventing the flexible cleaning component 220 from falling off the roller 210.

[0091] In some embodiments, there is a gap between the ends of the two roller brush assemblies 200 facing each other, and the air inlet 102 is positioned directly opposite the gap. This creates an empty area in front of the air inlet 102, improving the suction efficiency of the cleaning airflow and providing greater negative pressure suction to draw the hair fibers rolled up by the roller brush assemblies 200 into the device.

[0092] Understandably, the gap size can be L, where 10mm≤L≤30mm. This is to prevent the gap from being too small, which would hinder the flow of fibers, hair, and debris into the air intake 102, and to prevent the gap from being too large, which would result in insufficient coverage of the roller brush assembly 200 and affect the cleaning effect.

[0093] For example, the specific values ​​that can be used for the gap dimension L between the two roller brush assemblies 200 include, but are not limited to, 10mm, 11mm, 15mm, 20mm, 25mm, 29mm, 30mm, etc., and this application embodiment does not make specific limitations on this.

[0094] It should be noted that in this embodiment, the two roller brush assemblies 200 are arranged opposite each other at the ends with narrower outer diameters. Therefore, the two roller brush assemblies 200 form a roller brush structure that is wide at both ends and narrow in the middle in the roller brush cavity 101, so that the hair fibers can gather in a narrower area and be more easily sucked into the air inlet 102 in the middle of the roller brush cavity 101.

[0096] In this embodiment of the application, the cleaning device 10 may further include a drive component 300, and the two roller brush components 200 may be driven to rotate by the drive component 300 to achieve a better cleaning effect.

[0097] Each of the two roller brush assemblies 200 includes a fixed end 201 and a free end 202. The free ends 202 of the two roller brush assemblies 200 face each other and are positioned close to the air intake 102. The drive assembly 300 has two drive ends 301. The fixed ends 201 of the two roller brush assemblies 200 are located at both ends of the roller brush cavity 101 along the first direction and are respectively connected to the two drive ends 301.

[0098] It is understandable that the fixed end 201 is the end with a larger outer diameter of the roller brush assembly 200, and the free end 202 is the end with a smaller outer diameter of the roller brush assembly 200. That is, the driving end 301 of the driving assembly 300 is located at both ends of the roller brush cavity 101. In this way, the driving assembly 300 can be reasonably arranged to make full use of the space at the ends of the roller brush assembly 200, so as to ensure that the two roller brush assemblies 200 can rotate smoothly for cleaning.

[0099] It should be noted that the two roller brush assemblies 200 can share the same drive unit 310, or they can be driven by different drive units 310. This application does not make specific limitations in this regard. The specific drive structure of the drive assembly 300 will be described in detail below through different examples.

[0100] Please refer to Figure 8 As an optional implementation, the drive assembly 300 may include two drive units 310 and two transmission mechanisms 320, with the two drive units 310 respectively connected to the two transmission mechanisms 320, and the two transmission mechanisms 320 respectively connected to the two roller brush assemblies 200.

[0101] The transmission mechanism 320 includes a flexible transmission element 321 and two transmission wheels 322. One of the two transmission wheels 322 is connected to the drive unit 310, and the other of the two transmission wheels 322 is coaxially connected to the fixed end 201 of the roller 210. The flexible transmission element 321 is wound around the two transmission wheels 322.

[0102] It is understandable that the two drive units 310 can be controlled independently, and the two roller brush assemblies 200 can be driven by the two drive units 310 respectively, so as to realize the independent rotation of the two roller brush assemblies 200, simplify the transmission structure, and ensure the stability and reliability of the drive structure.

[0103] For example, the drive unit 310 can be a motor, and the output shaft of the motor is coaxially connected to one of the transmission wheels 322. The flexible transmission component 321 can be a synchronous belt, wire rope, chain, or other transmission component, and the transmission wheel 322 can be a corresponding synchronous pulley, guide wheel, sprocket, or other transmission component.

[0104] Please refer to Figure 9 As another optional implementation, the drive assembly 300 may include a drive unit 310, a drive member 330 and two transmission mechanisms 320. The drive unit 310 is configured to drive the drive member 330 to rotate. The two ends of the drive member 330 are respectively connected to the two transmission mechanisms 320, and the two transmission mechanisms 320 are respectively connected to the two roller brush assemblies 200.

[0105] The transmission mechanism 320 includes a flexible transmission element 321 and two transmission wheels 322. One of the two transmission wheels 322 is coaxially connected to the drive element 330, and the other of the two transmission wheels 322 is coaxially connected to the fixed end 201 of the roller 210. The flexible transmission element 321 is wound around the two transmission wheels 322.

[0106] For example, the drive component 330 can be a long shaft connected with gears, and the drive unit 310 can be a motor. The output end of the motor is coaxially connected with a gear, which can mesh with the gear on the drive component 330 to drive the drive component 330 to rotate. The drive component 330 is used to drive the corresponding transmission wheel 322 in the two transmission mechanisms 320 to rotate synchronously. Thus, two roller brush assemblies 200 can be driven synchronously by a single drive unit 310, simplifying the drive structure and reducing space occupation.

[0107] In some embodiments, the roller brush assembly 200 has a connecting hole 213 coaxially arranged with its rotation axis. The connecting hole 213 is provided with an internal thread and faces the corresponding transmission mechanism 320. The drive assembly 300 may also include a connector 340. The transmission wheel 322, which is coaxially connected with the fixed end 201 of the roller 210, is fixed to the connector 340. The connector 340 is inserted into the connecting hole 213 and threadedly connected to the connecting hole 213, thereby ensuring that the axes of the roller brush assembly 200 and the transmission wheel 322 are collinear and avoiding vibration during the rotation of the roller brush assembly 200.

[0108] In addition, the connector 340 and the connecting hole 213 of the roller 210 can also be connected by an interference fit or by a pin connection, and this application embodiment does not specifically limit this.

[0109] This application provides a cleaning device comprising a main body and two roller brush assemblies. The main body has a roller brush cavity, and the two roller brush assemblies are coaxially disposed within the roller brush cavity along a first direction. An air intake is provided within the roller brush cavity, with the air intake facing the ends of the two roller brush assemblies. Each roller brush assembly includes a roller and multiple flexible cleaning elements. The multiple flexible cleaning elements are spaced apart on the side wall of the roller, and each flexible cleaning element protrudes radially from the roller surface. At least one of the multiple flexible cleaning elements has a greater radial height along the roller than the end closest to the air intake. Thus, during cleaning, hair fibers rolled up on each roller brush assembly can slide from the higher end of the flexible cleaning element to the lower end, allowing the hair fibers to rotate and approach the air intake. The hair fibers then detach from the roller brush assembly at the end closest to the air intake and are drawn into the air intake, thereby preventing hair fibers from tangling on the roller brush assembly and improving the ease of cleaning the roller brush assembly.

[0110] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
