Description

Technical Field

[0001] This application relates to the field of cleaning product technology, and more particularly to a roller brush assembly and cleaning equipment. 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, when cleaning soft surfaces, hair fibers tend to get tangled on the roller brush as it rotates due to the suction from the air inlet, making them difficult to clean. Utility Model Content

[0005] This application provides a roller brush assembly and cleaning device to solve the technical problem that when cleaning soft surfaces, hair fibers easily become entangled on the roller brush as it rotates under the suction of the air inlet, making them difficult to clean.

[0006] In a first aspect, this application provides a roller brush assembly for use in a cleaning device, wherein the roller brush assembly is rotatably disposed on the cleaning device. The roller brush assembly includes a roller and at least one flexible cleaning element disposed on the surface of the roller.

[0007] The roller is equipped with ventilation holes; when the roller brush assembly rotates, the ventilation holes form an air passage for airflow, and the airflow direction of the air passage is at an angle to the axis of the roller.

[0008] The roller brush assembly provided in this application creates an airflow path on the roller by setting ventilation holes on the roller. In this way, when the roller brush assembly rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning equipment can flow through the ventilation holes on the roller, changing the direction of the suction force generated by the air inlet of the cleaning equipment, improving the overall airflow path of the cleaning equipment, reducing the impact of inward suction on hair fibers, and preventing hair fibers from getting tangled on the roller brush assembly.

[0009] As an alternative implementation, ventilation holes penetrate the roller in the circumferential direction of the roller brush assembly.

[0010] This design allows airflow to pass through the roller quickly, improving airflow efficiency.

[0011] As an alternative implementation, the center of the ventilation hole is spaced from the axis of rotation of the roller along the radial direction of the roller.

[0012] With this configuration, as the roller brush assembly rotates, it can drive airflow and increase the speed at which the cleaning equipment draws in airflow.

[0013] As an alternative implementation, the ventilation holes extend axially along the roller; or, the ventilation holes extend spirally along the roller.

[0014] This configuration increases the ventilation area along the length of the roller brush assembly, thereby improving airflow efficiency.

[0015] As an alternative implementation, the length of the ventilation hole is matched with the length of the roller.

[0016] This design ensures that airflow passes through the ventilation holes in all areas cleaned along the length of the roller brush assembly, preventing fibers and hair from getting tangled on the roller.

[0017] As an optional implementation, there can be multiple ventilation holes, which are spaced apart along the axial direction of the roller.

[0018] This configuration increases the number of airflow paths through the roller, improving cleaning performance.

[0019] As an alternative implementation, the roller has multiple baffle structures with ventilation holes formed between adjacent baffle structures.

[0020] With this configuration, the baffle structure can provide support and reinforcement, thereby increasing the structural strength of the roller.

[0021] This design ensures efficient airflow while maintaining good structural strength of the roller.

[0022] As an optional implementation, the area of ​​the ventilation hole is S1, and the axial cross-sectional area of ​​the roller is S2, wherein 1%≤S1 / S2<1, to ensure smooth airflow.

[0023] As an optional implementation, the roller may include a roller body, two connecting ends and at least one support portion, with the two connecting ends respectively connected to both ends of the roller body in the axial direction, and the two ends of the support portion respectively connected to the connecting ends at both ends of the roller body.

[0024] The ventilation hole may include a first ventilation hole, and there is a gap between the support and the roller to form the first ventilation hole.

[0025] This design increases the overall outer diameter of the roller, weakens the effect of the inward suction of the cleaning device on hair fibers, and reduces hair tangling.

[0026] As an alternative implementation, the roller includes a roller body, with ventilation holes formed in the roller body and extending through its outer surface. This allows the ventilation holes to be formed directly during the roller body machining process, reducing production costs.

[0027] As an optional implementation, the roller includes two connecting ends and multiple supporting parts. Both ends of the multiple supporting parts are connected to the two connecting ends respectively, and they are spaced apart circumferentially around the connecting ends to form ventilation holes. This allows the roller to have a hollow structure overall, increasing the ventilation capacity of the ventilation holes.

[0028] As an alternative implementation, the support portion is provided with a through groove extending axially along the roller brush assembly, and a flexible cleaning element is inserted into the through groove; at least a portion of the structure of the flexible cleaning element protrudes radially from the through groove to the outside of the roller.

[0029] This design improves the cleaning effect by using flexible cleaning components to squeeze and rub the surface to be cleaned.

[0030] As an alternative implementation, the edge of the flexible cleaning element on the side away from the roller is parallel to or at an angle to the inner wall of the through groove on the side away from the roller's central axis.

[0031] This configuration ensures that the flexible cleaning components provide a good cleaning effect on all surfaces to be cleaned along the length of the roller.

[0032] As an alternative implementation, the flexible cleaning component has a connecting portion located within the through groove, the cross-sectional shape of the connecting portion matching the cross-sectional shape of the through groove; the surface of the connecting portion away from the central axis of the roller is parallel to or at an angle to the inner wall of the through groove on the side closer to the central axis of the roller.

[0033] This design improves the reliability of the flexible cleaning component's insertion and installation on the support, preventing the flexible cleaning component from shaking or falling off.

[0034] As an optional implementation, there can be multiple connecting parts, which are spaced apart along the length of the through groove.

[0035] The ventilation hole may include a second ventilation hole, which is disposed on the support portion, and the gap between the second ventilation hole and the adjacent connecting portion is opposite.

[0036] This design increases the number of ventilation holes and improves airflow efficiency.

[0037] As an optional implementation, the first ventilation hole and the second ventilation hole are offset along the axial direction of the roller; or, the first ventilation hole and the second ventilation hole are arranged in a one-to-one correspondence along the axial direction of the roller.

[0038] This design creates a honeycomb-like ventilation hole pattern on the roller cross-section, which disperses the airflow and prevents hair from getting tangled on the roller brush assembly.

[0039] As an alternative implementation, the edge of the flexible cleaning element on the side away from the central axis of the roller has an angle with the central axis of the roller.

[0040] This design increases the degree of deformation of the flexible cleaning component, which lifts the hair through squeezing and friction.

[0041] As an optional implementation, the roller brush assembly may further include an end cap connected to the axial end of the roller, and the end cap having a slot on the side facing the flexible cleaning element, the end of the flexible cleaning element being inserted into the slot; wherein the groove depth of the slot along the roller axial direction is greater than or equal to 1% of the axial length of the roller and less than or equal to 10% of the axial length of the roller.

[0042] This design improves the installation stability of the flexible cleaning components while preventing hair fibers from getting tangled at both ends of the roller.

[0043] Secondly, this application provides a cleaning device, which includes a device body and a roller brush assembly as described above, the roller brush assembly being rotatably mounted on the device body.

[0044] As an alternative implementation, the device body is provided with a roller brush cavity, which has an opening facing one side of the device body. The roller brush assembly is located in the roller brush cavity and protrudes from the opening to contact the surface to be cleaned.

[0045] The contour shape of the brush cavity wall matches the contour shape of the brush assembly; the outer contour diameter of the brush assembly is 1%-90% of the diameter of the brush cavity.

[0046] This application provides a roller brush assembly and a cleaning device. The roller brush assembly is used in the cleaning device and is rotatably mounted on the cleaning device. The roller brush assembly includes a roller and at least one flexible cleaning element, which is disposed on the surface of the roller. The roller has ventilation holes. When the roller brush assembly rotates, the ventilation holes form an airflow path for airflow, and the airflow direction of this airflow path forms an angle with the axial direction of the roller. When the roller brush assembly rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning device can flow through the ventilation holes on the roller, changing the direction of the suction force generated by the air intake of the cleaning device, improving the overall airflow path of the cleaning device, reducing the impact of inward suction on hair fibers, and preventing hair fibers from getting tangled on 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 in orders other than those illustrated or described herein.

[0073] 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.

[0074] 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.

[0075] 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. Cleaning devices typically consist of a casing and a fan unit housed within it. The airflow generated by the fan unit creates suction at the air inlet on the casing. A roller brush can be positioned at the air inlet; this brush rolls across the surface being cleaned, picking up dust and hair, which are then drawn into the device by the suction, thus achieving the cleaning function.

[0076] However, under the suction of the air inlet, hair fibers easily get tangled on the roller brush as it rotates, and the tangling becomes tighter and tighter, making it difficult for the roller brush to clean.

[0077] In addition, when cleaning soft surfaces such as bedding, clothes, and sofas, current cleaning equipment often results in concave surfaces where hair fibers tend to adhere and are difficult to be sucked into the cleaning equipment. As a result, even with repeated cleaning and the roller brush rolling back and forth, it is still difficult to remove all hair fibers, leading to poor cleaning results.

[0078] To address the aforementioned technical problems, this application provides a roller brush assembly and a cleaning device. The roller brush assembly, through its roller structure design, incorporates ventilation holes on the roller. This allows airflow to pass through the periphery of the roller brush assembly during cleaning, while additional airflow paths are formed on the roller of the roller brush assembly. This alters the direction of suction generated by the air inlet on the cleaning device, thereby improving the overall airflow layout of the cleaning device. It also prevents hair fibers from becoming entangled on the roller brush assembly, making it easier for any attached hair fibers to be drawn into the cleaning device, resulting in a better cleaning effect.

[0079] The following is an example illustrating the application scenarios of the roller brush assembly and cleaning equipment provided in the embodiments of this application.

[0080] The roller brush assembly provided in this application embodiment is used in cleaning equipment. The cleaning equipment 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 for carpets, bed sheets and quilts, sofas, clothing, etc. This application embodiment does not make specific limitations in this regard.

[0082] See Figures 1 to 8As shown in the illustration, this application provides a roller brush assembly 100, which is applied in a cleaning device 10. When the cleaning device 10 cleans a surface to be cleaned, the roller brush assembly 100 can contact the surface to be cleaned. The roller brush assembly 100 can rotate on the cleaning device 10, and as the cleaning device 10 moves, the roller brush assembly 100 can roll and rub the surface to be cleaned to clean dust and hair adhering to the surface.

[0083] The roller brush assembly 100 provided in this application embodiment includes a roller 110 and at least one flexible cleaning element 120, the flexible cleaning element 120 being disposed on the surface of the roller 110. The roller 110 is rotatably connected to the cleaning device 10, and the roller 110 supports the flexible cleaning element 120. The flexible cleaning element 120 is elastic, and when the flexible cleaning element 120 contacts the surface to be cleaned, it can be squeezed to generate elastic deformation, thereby increasing its friction with the surface to be cleaned. Through friction and patting of the surface to be cleaned, it picks up the attached dust and fibers.

[0084] The roller 110 is provided with ventilation holes 111. When the roller brush assembly 100 rotates, the ventilation holes 111 form an air passage for airflow, and the airflow direction of the air passage is at an angle to the axial direction of the roller 110.

[0085] It is understandable that a fan can be installed on the cleaning device 10 to generate negative pressure airflow. The negative pressure airflow is used in conjunction with the roller brush assembly 100 to use negative pressure suction to draw dust and hair fibers from the surface to be cleaned into the cleaning device 10.

[0086] In this embodiment, the negative pressure airflow generated on the cleaning device 10 can flow through the periphery of the roller brush assembly 100 on the one hand, and through the air path formed by the ventilation hole 111 on the other hand, so that the periphery of the roller 110 and the roller 110 itself can form an air path for airflow, thereby improving the air volume and airflow efficiency, and thus avoiding hair fibers remaining on the surface to be cleaned.

[0087] It should be noted that when the roller brush assembly 100 rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning device 10 can flow through the ventilation holes 111 on the roller 110. The soft cleaning parts on the surface of the roller 110 can still provide a good cleaning effect of friction and patting on the surface to be cleaned. At the same time, the roller 110 does not completely block the airflow, thereby changing the direction of the suction force generated by the air intake on the cleaning device 10. Some airflow bypasses the outside of the roller 110, but some airflow can pass directly through the roller 110, reducing wind resistance and improving the overall airflow path of the cleaning device 10. This prevents hair fibers from getting tangled on the roller brush assembly 100, making it easier for hair fibers to be sucked into the cleaning device 10 and improving the cleaning effect.

[0088] The structure of the ventilation hole 111 will be described in detail below.

[0089] Please continue to refer to Figures 1 to 8 In some embodiments, ventilation holes 111 penetrate baffle structure 112 in the circumferential direction of the roller brush assembly 100, thereby allowing airflow to pass through roller 110 quickly and improving airflow efficiency.

[0090] It is understandable that on the cleaning device 10, the air inlet opposite to the roller brush assembly 100 is usually located on the side of the roller brush assembly 100. When the air inlet generates negative pressure suction, as the roller brush assembly 100 rotates, the ventilation hole 111 can be understood as forming an annular air path around the center of the roller 110, and the airflow is more likely to pass through the roller 110 radially and be sucked into the air inlet.

[0091] In some embodiments, the center of the ventilation hole 111 is spaced from the axis of rotation of the roller 110 along the radial direction of the roller 110.

[0092] The ventilation holes 111 are offset relative to the central axis of the roller 110. This allows airflow to pass more easily along the rotation direction of the ventilation holes 111 as the roller brush assembly 100 rotates at high speed, thus significantly reducing airflow resistance. Furthermore, the rotation of the roller brush assembly 100 drives airflow, increasing the speed at which the cleaning device 10 draws in air.

[0093] For example, the ventilation hole 111 can extend along the axial direction of the roller 110, thereby increasing the ventilation area in the length direction of the roller brush assembly 100 and improving airflow efficiency.

[0094] For example, the ventilation hole 111 extends spirally along the axial direction of the roller. The extending direction of the ventilation hole 111 is consistent with the extending direction of the baffle structure 112, and the overall outline of the roller brush assembly 100 can be a twisted structure.

[0095] The airflow through the ventilation hole 111 can flow in any direction except parallel to the axial direction of the roller 110.

[0096] It should be noted that the extension direction of the ventilation hole 111 can be parallel to the axial direction of the roller 110, or it can have a certain angle with the axial direction of the roller 110. The shape of the ventilation hole 111 can be square, rectangular, round, elliptical, or other shapes, and this application embodiment does not specifically limit it.

[0097] Furthermore, multiple areas with ventilation holes 111 can be provided around the roller 110. For example, the ventilation holes 111 can be positioned opposite the flexible cleaning element 120. As the roller brush assembly 100 rotates, an approximately annular airflow path can be formed on the roller 110, into which airflow from outside the roller brush assembly 100 can enter and exit near the suction port of the cleaning device 10.

[0098] In each corresponding area of ​​the circumference of the roller 110, a single ventilation hole 111 or multiple ventilation holes 111 can be provided, which will be explained in detail below.

[0099] Figure 9 This is a schematic diagram of another structure of the roller brush assembly provided in the embodiments of this application; Figure 10 A schematic diagram of the roller in another structure of the roller brush assembly provided in this application embodiment; Figure 11 This is a cross-sectional view of the roller in another structure of the roller brush assembly provided in an embodiment of this application.

[0100] Please refer to Figures 9 to 11 In some embodiments, when the vent 111 is a single vent, the length of the vent 111 matches the length of the roller 110. Airflow can pass through the vent 111 to all areas cleaned along the length of the roller brush assembly 100, thereby preventing fibers and hair from getting tangled on the roller 110.

[0101] Please continue to refer to Figures 1 to 8 In other embodiments, there may be multiple ventilation holes 111, which are spaced apart along the axial direction of the roller 110, thereby increasing the number of airflow paths through the roller 110 and improving the cleaning effect.

[0102] It is understandable that when the roller brush assembly 100 rotates, each ventilation hole 111 can be understood as forming an air path. Multiple air paths can disperse the airflow passing through the roller 110, thereby reducing wind resistance and reducing the noise generated when the roller brush assembly 100 rotates for cleaning.

[0103] For example, the roller 110 has multiple baffle structures 112, with ventilation holes 111 formed between adjacent baffle structures 112. The baffle structures 112 can provide support and reinforcement, improving the structural strength of the roller 110. This application embodiment does not limit the specific number of baffle structures 112.

[0104] In this embodiment, the volume of the baffle structure 112 is greater than or equal to 1% of the volume of the roller 110, and less than or equal to 80% of the volume of the roller 110. While ensuring airflow efficiency, this ensures that the roller 110 has good structural strength.

[0105] For example, the ratio of the volume of the baffle structure 112 to the volume of the roller 110 can be 1%, 2%, 10%, 30%, 45%, 60%, 70%, 79%, 80%, etc., and this application embodiment does not specifically limit it.

[0106] It should be noted that the baffle structure 112 can be welded to the main body structure of the roller 110, or the baffle structure 112 can be integrally formed with the roller 110. This application embodiment does not specifically limit this.

[0107] In some embodiments, the area of ​​the ventilation hole 111 is S1, and the axial cross-sectional area of ​​the roller 110 is S2, wherein 1% ≤ S1 / S2 < 1, so as to ensure smooth airflow.

[0108] It is understandable that the area S1 of the ventilation hole 111 refers to the sum of the areas of all ventilation holes 111 on the axial section of the roller 110.

[0109] It should be noted that the ventilation hole 111 can be formed by different structures on the roller 110, and correspondingly, the roller 110 can be designed in different structural forms.

[0110] The structure of roller 110 will be described in detail below.

[0111] Please continue to refer to Figures 1 to 8 In some embodiments, the roller 110 may include a roller body 113 and a connecting end 114, the baffle structure 112 may include a support portion 115, the connecting end 114 is connected to both ends of the roller body 113 in the axial direction, and the two ends of the support portion 115 are respectively connected to the connecting ends 114 at both ends of the roller body 113.

[0112] Understandably, the roller 113 can be an elongated cylindrical structure. The connecting end 114 is located at the axial end of the roller 113, and its radial area is larger than the maximum radial cross-section of the roller 113, thereby supporting the overall frame structure of the roller 110. The support portion 115 is used to install the flexible cleaning component 120.

[0113] The ventilation hole 111 may include a first ventilation hole 111a. There is a gap between the support part 115 and the roller 113 to form the first ventilation hole 111a. This can improve the convenience of processing and forming the roller 110 and reduce the production cost.

[0114] For example, the support portion 115 can be welded to the connecting end 114, or the roller 113, the connecting end 114 and the support portion 115 can be integrally formed. This application embodiment does not specifically limit this.

[0115] In other embodiments, the roller 110 includes a roller body 113, with ventilation holes 111 formed in the roller body 113 and extending through its outer surface. This allows the ventilation holes 111 to be formed directly during the machining of the roller body 113, reducing production costs.

[0116] Understandably, compared to the previous example, in this example, the ventilation hole 111 is directly disposed on the roller 113. The roller 113 has a cylindrical structure, and both ends of the ventilation hole 111, which are for air inlet and outlet, are located on the outer surface of the roller 113.

[0117] In another embodiment, the roller 110 may include two connecting ends 114 and a plurality of support portions 115. Both ends of the plurality of support portions 115 are respectively connected to the two connecting ends 114 and are spaced apart around the connecting ends 114 to form ventilation holes 111. In this way, the roller 110 can have a hollow structure as a whole, increasing the ventilation volume of the ventilation holes 111.

[0118] It is understandable that, compared with the previous example, this example may not have a roller 113. Instead, a cage-like frame structure is formed by the connecting end 114 and the support part 115, which can maximize the ventilation area of ​​the ventilation hole 111.

[0120] Please refer to Figures 12 to 15 and combined Figures 1 to 8 In some embodiments, the support portion 115 is provided with a through groove 1151 extending axially along the roller brush assembly 100, and the flexible cleaning member 120 is inserted into the through groove 1151. At least a portion of the structure of the flexible cleaning member 120 protrudes radially from the through groove 1151 to the outside of the roller 110. By squeezing and rubbing the surface to be cleaned by the flexible cleaning member 120, the cleaning effect can be improved.

[0121] There can be multiple flexible cleaning components 120, and the multiple flexible cleaning components 120 are arranged at intervals along the circumference of the roller 110.

[0122] Understandably, during the rotation and cleaning process of the roller brush assembly 100, multiple flexible cleaning elements 120 can sequentially contact and pat the surface to be cleaned, so that the roller brush assembly 100 can have a better cleaning effect.

[0123] For example, the flexible cleaning element 120 can be one or a combination of adhesive strips, brushes, etc. For instance, the flexible cleaning element 120 can be an adhesive strip. When an adhesive is used as the flexible cleaning element 120, 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.

[0124] For example, multiple flexible cleaning elements 120 can be arranged in parallel and all extend along the axial direction of the roller 110. This ensures that a flexible cleaning element 120 can contact the surface being cleaned along the axial direction of the roller brush assembly 100, increasing the cleaning range. Correspondingly, the extending direction of the ventilation holes 111 is parallel to the extending direction of the flexible cleaning elements 120.

[0125] For example, multiple flexible cleaning elements 120 extend spirally along the circumferential outer wall of the roller 110. Thus, as the roller brush assembly 100 rolls along the cleaning direction of the cleaning device 10, different positions along the extension direction of the flexible cleaning elements 120 can sequentially contact the surface to be cleaned as the roller brush assembly 100 rolls, without obstructing the negative pressure airflow of the suction port, thereby improving the efficiency of dust and hair suction. Correspondingly, the extension direction of the ventilation holes 111 is consistent with the extension direction of the flexible cleaning elements 120.

[0126] It should be noted that the number of flexible cleaning parts 120 can be two, three, four, five or more, and this application embodiment does not specifically limit this.

[0127] In some embodiments, the edge of the flexible cleaning member 120 away from the roller 110 is parallel to or at an angle to the inner wall of the through groove 1151 away from the central axis of the roller 110, thereby ensuring that the flexible cleaning member 120 has a good cleaning effect on the surface to be cleaned in the length direction of the roller 110.

[0128] For example, when the upper edge of the through groove 1151 is an arc-shaped surface, the tangent of its upper edge can be parallel to the upper edge of the flexible cleaning member 120. When the upper edge of the through groove 1151 is a plane, its upper edge can be parallel to the upper edge of the flexible cleaning member 120.

[0129] For example, the upper edge of the through groove 1151 and the upper edge of the flexible cleaning member 120 have an angle, including but not limited to 1°, 2°, 10°, 20°, 30°, 45°, 60°, etc., and the embodiments of this application do not specifically limit this.

[0130] In some embodiments, the flexible cleaning member 120 has a connecting portion 121 located within the through groove 1151, and the cross-sectional shape of the connecting portion 121 matches the cross-sectional shape of the through groove 1151. The surface of the connecting portion 121 on the side away from the central axis of the roller 110 is parallel to or at an angle to the inner wall of the through groove 1151 on the side closer to the central axis of the roller 110.

[0131] It is understandable that the flexible cleaning component 120 is inserted into the through groove 1151 from the end of the roller 110. The cross-sectional dimension of the connecting part 121 is less than or equal to the cross-sectional dimension of the through groove 1151. The cooperation between the connecting part 121 and the through groove 1151 can limit the flexible cleaning component 120 radially along the roller 110, improve the reliability of the flexible cleaning component 120 being inserted and installed on the support part 115, and prevent the flexible cleaning component 120 from shaking or falling off.

[0132] In some embodiments, there may be multiple connecting portions 121, which are spaced apart along the length of the through groove 1151. This allows a serrated skirt-like structure to be formed along the lower edge of the flexible cleaning member 120.

[0133] The ventilation hole 111 may include a second ventilation hole 111b, which is disposed on the support portion 115. The gap between the second ventilation hole 111b and the adjacent connecting portion 121 is opposite, thereby increasing the number of ventilation holes 111 and improving airflow efficiency.

[0134] For example, the first ventilation hole 111a and the second ventilation hole 111b are offset along the axial direction of the roller 110, so that the ventilation holes 111 on the cross section of the roller 110 are honeycomb-shaped, which disperses the airflow and prevents hair from being confined and wrapped on the roller brush assembly 100.

[0135] For example, the first ventilation hole 111a and the second ventilation hole 111b can be arranged one-to-one along the axial direction of the roller to improve the smoothness of airflow.

[0136] In some embodiments, the edge of the flexible cleaning element 120 on the side away from the central axis of the roller 110 forms an angle with the central axis of the roller 110. When the flexible cleaning element 120 comes into contact with the surface to be cleaned and is squeezed and deformed, the degree of deformation of the flexible cleaning element 120 can be increased, and hair can be more easily lifted by squeezing friction.

[0137] For example, the flexible cleaning element 120 may be provided with a protrusion at the center position along the axial direction of the roller 110.

[0138] In some embodiments, the roller brush assembly 100 may further include an end cap 130, which is connected to the axial end of the roller 110. The end cap 130 has a slot 131 on the side facing the flexible cleaning member 120, and the end of the flexible cleaning member 120 is inserted into the slot 131. The end cap 130 can limit the flexible cleaning member 120 along the axial direction of the roller 110, thereby improving the installation stability of the flexible cleaning member 120.

[0139] The groove depth of slot 131 along the axial direction of roller 110 is greater than or equal to 1% of the axial length of roller 110 and less than or equal to 10% of the axial length of roller 110. The insertion and engagement of end cap 130 and flexible cleaning component 120 can form a stop structure to prevent hair fibers from getting tangled at both ends of roller 110.

[0140] For example, the ratio of the groove depth of the slot 131 along the axial direction of the roller 110 to the axial length of the roller 110 can be 1%, 2%, 5%, 9%, 10%, etc., and this application embodiment does not specifically limit it.

[0141] Figure 16 Cross-sectional view of the cleaning equipment provided in the embodiments of this application. Figure 1 , Figure 17 Cross-sectional view of the cleaning equipment provided in the embodiments of this application. Figure 2 .

[0142] Please refer to Figure 16 and Figure 17 and combined Figures 1 to 8 This application provides a cleaning device 10, which includes a device body 200 and a roller brush assembly 100 as described above. The roller brush assembly 100 is rotatably mounted on the device body 200.

[0143] During cleaning operations, the side of the main body 200 connected to the roller brush assembly 100 faces the surface to be cleaned, allowing the roller brush assembly 100 to contact the surface. A motor is mounted on the main body 200, configured to drive the roller brush assembly 100 to rotate. As the main body 200 moves, the roller brush assembly 100 rolls on the surface to be cleaned, carrying up dust, mites, hair, and other debris, making it easier for these impurities to be sucked into the main body 200.

[0144] Understandably, the main body 200 of the device is equipped with an air intake 202, which is opposite to the roller brush assembly 100 and is connected to the air intake channel inside the main body 200. The main body 200 is equipped with a fan and a dust collection component. The fan is used to generate airflow in the air intake channel to create suction at the air intake 202. The sucked-in dust, mites, and fibers are stored in the dust collection component, which is detachably connected to the main body 200 for easy cleaning.

[0145] In some embodiments, the device body 200 is provided with a roller brush cavity 201, the roller brush cavity 201 having an opening facing one side of the device body 200, the roller brush assembly 100 being located in the roller brush cavity 201 and exposed from the opening to contact the surface to be cleaned.

[0146] In this embodiment, the contour shape of the brush cavity 201 matches the contour shape of the brush assembly 100, and the outer contour diameter of the brush assembly 100 is 1%-90% of the diameter of the brush cavity 201. Compared with the prior art, in this embodiment, the brush cavity 201 corresponds to the brush assembly 100, and the diameter of the brush cavity 201 is increased, which weakens the influence of the inward suction force of the air inlet 202 on the hair fibers and reduces the possibility of hair fibers getting tangled on the brush assembly 100.

[0147] For example, the ratio of the outer contour diameter of the roller brush assembly 100 to the diameter of the roller brush cavity 201 can be 1%, 2%, 10%, 30%, 50%, 70%, 80%, 89%, 90%, etc., and this application embodiment does not specifically limit it.

[0148] For example, the diameter of the roller brush cavity 201 is greater than or equal to 35 mm and less than or equal to 49 mm. The diameter of the roller brush cavity 201 can be 35 mm, 36 mm, 40 mm, 45 mm, 48 mm, 49 mm, etc., and this application embodiment does not specifically limit it.

[0149] This application provides a roller brush assembly and a cleaning device. The roller brush assembly is used in the cleaning device and is rotatably mounted on the cleaning device. The roller brush assembly includes a roller and at least one flexible cleaning element. The flexible cleaning element is disposed on the surface of the roller, and the roller has ventilation holes. When the roller brush assembly rotates, the ventilation holes form an airflow path for airflow. When the roller brush assembly rotates to clean the surface to be cleaned, the negative pressure airflow generated by the cleaning device can flow through the ventilation holes on the roller, increasing the airflow rate into the cleaning device, changing the direction of the suction force generated by the air inlet on the cleaning device, improving the overall airflow path of the cleaning device, weakening the impact of inward suction on hair fibers, and preventing hair fibers from getting tangled on the roller brush assembly.

[0150] 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.
