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] Vacuum cleaners, robotic vacuum cleaners, and other cleaning devices are commonly used in households. These devices are typically equipped with roller brushes. During the cleaning process, the roller brushes roll and rub against the surface to be cleaned, thereby picking up dust, hair, water stains, etc., and the cleaning device can suck up the picked-up debris into its interior.

[0003] In related technologies, roller brushes typically include a roller and multiple scraper strips, with the scraper strips usually protruding from the surface of the roller. The multiple scraper strips are spaced apart along the circumference of the rotating roller, and as the roller brush rotates, the multiple scraper strips can sequentially tap or rub the surface to be cleaned to achieve a cleaning effect.

[0004] However, when the roller brush rotates, some of the debris it picks up remains in the gaps between the scraper blades and is difficult to remove. When the roller brush stops rotating, the remaining debris can easily cause secondary pollution to the ground, resulting in poor cleaning effect. Utility Model Content

[0005] This application provides a roller brush assembly and cleaning equipment to solve the technical problem that some of the debris carried up by the roller brush during rotation remains between the scraper blades, which can easily cause secondary pollution to the ground.

[0006] In a first aspect, this application provides a roller brush assembly for a cleaning device, wherein the roller brush assembly is rotatably disposed on the cleaning device; the roller brush assembly includes a roller brush body and a plurality of scraper strips; the roller brush body has a plurality of protruding support portions, and the plurality of scraper strips are respectively disposed on the plurality of support portions and are arranged at intervals around the axial direction of the roller brush body on the periphery of the roller brush body; the scraper strips extend from a first end of the axial direction of the roller brush body to a second end of the axial direction of the roller brush body;

[0007] The scraper includes two extensions, the ends of which are connected; the two extensions have an included angle in their radial projection onto the brush body.

[0008] The roller brush assembly provided in this application designs the scraper on the roller brush body as a structure with two connected extensions at an angle, resulting in a V-shaped scraper protruding from the surface of the roller brush body. When the roller brush assembly rotates for cleaning, debris remaining between the scraper strips can flow and converge towards the center of the V-shaped structure under the guidance of the scraper strips, making it easier to be sucked into the brush assembly and enhancing its cleaning ability.

[0009] In one alternative embodiment, the brush body has a radial profile that overlaps with its centerline, and the connection points of the two extensions of the plurality of scrapers are both located on the radial profile.

[0010] With this configuration, when the rolling component rotates, the debris carried up from various positions in the circumference can converge towards the center of the roller brush component.

[0011] In one alternative embodiment, the cleaning device has an air intake; the connection position of the two extensions of the scraper is opposite to the air intake.

[0012] With this configuration, residual debris on the scraper blades gathers along the extension section to the position opposite the air inlet, making it easier to be sucked into the air inlet and preventing debris from remaining on the roller brush assembly.

[0013] In one alternative embodiment, around the circumference of the brush body, a protrusion and a recess are formed on opposite sides of the connection position of the two extensions, and the protrusions on different scraper blades have the same orientation.

[0014] With this configuration, channels for guiding waste can be formed between the extensions of adjacent scrapers, making it easier for waste to converge at the connection point of the extensions.

[0015] In one alternative implementation, as the roller brush assembly rolls forward along the cleaning direction of the cleaning device, one side of the recessed portion of each scraper first passes the air intake.

[0016] With this design, the debris collected on the scraper is more easily sucked into the air intake, preventing it from falling back to the ground when the roller brush assembly rolls.

[0017] In one alternative implementation, along the axial direction of the roller brush assembly, the projections of any two adjacent scraper strips are connected or partially overlap.

[0018] This configuration ensures that the scraper remains in contact with the ground throughout the rotation of the roller brush assembly, resulting in better cleaning performance.

[0019] In one optional embodiment, the roller brush body includes a roller brush shaft and a plurality of support portions, the plurality of support portions being connected to the periphery of the roller brush shaft and arranged sequentially at intervals around the axial direction of the roller brush shaft; the end of each support portion away from the roller brush shaft has a slot, and a plurality of scraper strips are provided in correspondence with the plurality of support portions and are respectively inserted into the slots of the plurality of support portions;

[0020] The slot includes two connected groove segments that have an included angle in their radial projection onto the brush body, such that the scraper inserted into the slot forms two extension segments.

[0021] This design allows the flexible squeegee to maintain its V-shaped structure, resulting in better cleaning performance.

[0022] In one alternative embodiment, at least a portion of the area between the brush shaft and the support portion is provided with a ventilation gap along the axial direction of the brush assembly.

[0023] This design creates a channel for airflow in the radial direction of the roller brush, preventing hair fibers from becoming entangled and difficult to clean.

[0024] In one alternative embodiment, the included angle between the projections of the two extensions in the radial direction of the brush body is greater than or equal to 162° and less than or equal to 174°.

[0025] This design keeps the angle between the two extension sections within a reasonable range, ensuring that the scraper has a better guiding effect on residual waste.

[0026] Secondly, this application provides a cleaning device, which includes a device body and the aforementioned roller brush assembly, the roller brush assembly being rotatably disposed on the device body.

[0027] The cleaning equipment provided in this application cleans the surface to be cleaned by using the aforementioned roller brush assembly, which avoids residual debris on the roller brush assembly and improves cleaning efficiency.

[0028] 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 brush body and multiple scraper strips. The multiple scraper strips are disposed on the roller brush body and are spaced apart around the axial direction of the roller brush body. The scraper strips extend from a first end of the roller brush body along its axial direction to a second end. Each scraper strip includes two extension sections, the ends of which are connected. The projections of the two extension sections in the radial direction of the roller brush body have an included angle, so that the scraper strips protruding from the surface of the roller brush body have a V-shaped structure. Debris remaining between the scraper strips can flow and converge towards the center of the V-shaped structure under the guidance of the scraper strips, thus making it easier to be sucked into the interior of the brush device and enhancing the cleaning ability of 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.

[0048] 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.

[0049] 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.

[0050] Vacuum cleaners, robotic vacuum cleaners, and floor scrubbers are common household cleaning devices. These appliances typically have roller brushes that, during cleaning, rotate and rub against the surface, lifting dust, hair, water stains, and other debris, which are then sucked into the cleaning device.

[0051] A roller brush typically consists of a roller and multiple scraper blades, which usually protrude from the surface of the roller. The multiple scraper blades are spaced apart along the circumference of the rotating roller. As the roller brush rotates, the blades sequentially tap or rub the surface to be cleaned to achieve a cleaning effect. However, when the roller brush rotates, some of the debris carried up remains in the gaps between the scraper blades, making it difficult to remove. When the roller brush stops rotating, the remaining debris can easily cause secondary pollution to the floor, resulting in poor cleaning effectiveness.

[0052] To address the aforementioned technical problems, this application provides a roller brush assembly and a cleaning device. The roller brush assembly features a V-shaped scraper structure designed so that the scraper protruding from the main body of the roller brush forms a V-shape. When the roller brush assembly rotates and cleans the debris that is left between the scraper strips, the debris will be guided towards the center of the V-shape by the scraper strips. This makes it easier for the debris to be sucked into the cleaning device, thus preventing debris from remaining on the roller brush assembly after cleaning.

[0053] The following is an example illustrating the application scenarios of the roller brush assembly and cleaning equipment provided in the embodiments of this application.

[0054] 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 types of the cleaning equipment in this application embodiment may include, but are not limited to, mite removers, vacuum cleaners, floor scrubbers, and robot vacuum cleaners. Depending on the product type, the cleaning equipment provided in this application embodiment can be used on soft surfaces such as carpets, sheets, sofas, and clothing, as well as hard surfaces such as floor tiles and floors. This application embodiment does not make any specific limitations in this regard.

[0055] Figure 1 An exploded view of the cleaning equipment provided in the embodiments of this application; Figure 2 A cross-sectional view of the cleaning equipment provided in the embodiments of this application; Figure 3 This is a schematic diagram of the structure of the roller brush assembly provided in the embodiments of this application; Figure 4 This is a schematic diagram of the structure of the roller brush body in the roller brush assembly provided in the embodiments of this application; Figure 5 for Figure 4 A partial view of position A in the middle.

[0056] See Figures 1 to 5 As shown, this application embodiment provides a roller brush assembly 100 for a cleaning device 10, and the roller brush assembly 100 is rotatably disposed on the cleaning device 10. When the cleaning device 10 cleans the surface to be cleaned, the roller brush assembly 100 can contact the surface to be cleaned, and as the cleaning device 10 moves, the roller brush assembly 100 can roll and rub the surface to be cleaned to clean dust, fibers, hair, water stains and other debris on the surface to be cleaned.

[0057] It should be noted that the cleaning device 10 has a roller brush chamber, and the roller brush assembly 100 is rotatably disposed within the roller brush chamber. The cleaning device 10 has an air inlet 11 facing the roller brush chamber, which provides negative pressure suction to draw the surface to be cleaned and dust, hair, etc., rolled up by the roller brush assembly 100 into the cleaning device 10. The roller brush assembly 100 and the air inlet 11 cooperate with each other to achieve the cleaning effect.

[0058] The roller brush assembly 100 provided in this application embodiment includes a roller brush body 110 and a plurality of scraper strips 120. The roller brush body 110 has a plurality of protruding support portions 112, and the plurality of scraper strips 120 are respectively disposed on the plurality of support portions 112 and are arranged at intervals around the circumference of the roller brush body 110. The scraper strips 120 extend from a first end in the axial direction of the roller brush body 110 to a second end in the axial direction of the roller brush body 110.

[0059] Understandably, the roller brush body 110 can be rotatably connected to the cleaning device 10. The roller brush body 110 supports the scraper strips 120. The scraper strips 120 are elastic and can be made of rubber. When the scraper strips 120 come into contact with the surface to be cleaned, they can be squeezed to produce elastic deformation, thereby increasing the friction between them and the surface to be cleaned. During cleaning, the roller brush body 110 rotates, causing multiple scraper strips 120 to rub and pat the surface to be cleaned in sequence, lifting up the attached dust, fibers, hair, and other debris. At the same time, the cleaning device 10 can be equipped with a fan 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 suck the surface to be cleaned and the debris lifted by the roller brush assembly 100 into the cleaning device 10.

[0060] Please continue to refer to Figures 1 to 5 In some embodiments, the scraper 120 includes two extensions 121, the ends of which are connected. The two extensions 121 have an included angle in their radial projections onto the brush body 110.

[0061] Understandably, the two extension sections 121 form a V-shaped structure on the surface of the brush body 110. Along the length of the extension section 121, the extension section 121 can guide the debris remaining between the adjacent scraper blades 120 on the brush assembly 100, so that the debris can converge between the two extension sections 121.

[0062] It should be noted that the debris remaining between the scraper blades 120 flows and converges towards the center of the V-shaped structure, making it easier to be sucked into the floor brush device and enhancing the cleaning ability of the roller brush assembly 100.

[0063] Define the rotation axis of the roller brush assembly 100 as the X direction.

[0064] For example, the connection position of the two extensions 121 can be the middle position of the roller brush body 110 along the X direction. When dust particles and other debris carried by the two extensions 121 remain on the roller brush assembly 100, as the roller brush assembly 100 rotates and under the suction of the air inlet 11, they will flow from both ends of the roller brush assembly 100 axially towards the middle with the airflow.

[0065] For example, one of the two extension segments 121 extends from a first end of the brush body 110 in the axial direction to the middle position of the brush body 110, and the other of the two extension segments 121 extends from a second end of the brush body 110 in the axial direction to the middle position of the brush body 110. The extension segments 121 extend obliquely on the brush body 110 with respect to the X direction, and the two oblique extension segments 121 are connected to form a V-shaped structure.

[0066] In some embodiments, the brush body 110 has a radial section that overlaps with its centerline S, and the connection points of the two extensions 121 of the plurality of scrapers 120 are both located on the radial section.

[0067] Understandably, the radial section of the roller brush body 110 is perpendicular to the X direction. Multiple scraper blades 120 each form a V-shaped structure, with the center of each V-shape located on the radial section of the roller brush body 110. When the roller assembly rotates, debris carried up from various positions in the circumferential direction can converge towards the center of the roller brush assembly 100.

[0068] For example, the cleaning device 10 has an air intake 11. The connection position of the two extensions 121 of the scraper 120 is opposite to the air intake 11. In this way, residual debris on the scraper 120 is collected along the extensions 121 to the position opposite the air intake 11, and is more easily sucked into the air intake 11, avoiding debris residue on the roller brush assembly 100 and improving cleaning efficiency.

[0069] In some embodiments, around the circumference of the roller brush body 110, a protrusion 122 and a recess 123 are formed on opposite sides of the connection position of the two extensions 121, and the protrusions 122 on different scraper blades 120 have the same orientation.

[0070] Understandably, during the floor cleaning process, as the roller brush assembly 100 rotates, the debris remaining between the scraper blades 120 of the roller brush assembly 100 can collect on one side of the recess 123 of the scraper blade 120, that is, the recess 123 serves to collect the debris. A channel for guiding debris can be formed between the extensions 121 of adjacent scraper blades 120, making it easier for debris to collect at the connection position of the extensions 121.

[0071] For example, the extensions 121 on adjacent scraper strips 120 can be equidistantly arranged on the brush body 110, that is, the spacing between scraper strips 120 remains equal along the extension direction of the extension.

[0072] In some embodiments, as the roller brush assembly 100 rolls forward along the cleaning direction of the cleaning device 10, one side of the recess 123 of each scraper 120 passes the air intake 11 first.

[0073] The cleaning direction of the cleaning device 10 is defined as the Y direction, which is perpendicular to the X direction.

[0074] It is understandable that the debris collects on one side of the recess 123 of the scraper 120. The recess 123 passes through the air intake 11 first, making it easier for the debris collected on the scraper 120 to be sucked into the air intake 11, thus preventing the debris from falling back to the ground when the roller brush assembly 100 rolls.

[0075] For example, taking a side view of the cleaning device 10 as an example, the roller brush assembly 100 is located in front of the air intake 11. As the cleaning device 10 moves forward, the roller brush assembly 100 rotates counterclockwise. When the scraper 120 rotates with the roller brush assembly 100 to the lower side of the roller brush body 110, the recess 123 faces the air intake 11. After passing the air intake 11, the scraper 120 rotates to the upper side of the roller brush body 110, and the scraper 120 on the upper side of the roller brush body 110 has a protrusion 122 facing the air intake 11.

[0076] In some embodiments, along the axial direction of the roller brush assembly 100, the projections of any two adjacent scraper blades 120 are connected or partially overlap. In this way, during the rotation of the roller brush assembly 100, the scraper blades 120 can always maintain contact with the ground, resulting in a better cleaning effect.

[0077] The structure of the roller brush body 110 and the specific connection method of the scraper 120 are described in detail below.

[0078] Figure 6 Radial cross-section of the first structure of the roller brush body in the roller brush assembly provided in the embodiments of this application. Figure 1 ; Figure 7 Radial cross-section of the second structure of the roller brush body in the roller brush assembly provided in the embodiments of this application. Figure 1 ; Figure 8 A schematic diagram of the ventilation gap on the brush body in the brush assembly provided in this application embodiment; Figure 9 This is an exploded view of the roller brush assembly provided in an embodiment of this application.

[0079] Please refer to Figures 6 to 9 and combined Figures 3 to 5In some embodiments, the brush body 110 may include a brush shaft 111 and a plurality of support portions 112. The plurality of support portions 112 are connected to the periphery of the brush shaft 111 and are arranged sequentially at intervals around the axial direction of the brush shaft 111. The end of the support portion 112 away from the brush shaft 111 has a slot 113. A plurality of scraper strips 120 are correspondingly disposed with the plurality of support portions 112 and are respectively inserted into the slots 113 of the plurality of support portions 112.

[0080] The slot 113 includes two connected groove segments, the two groove segments having an included angle in their radial projection onto the brush body 110, so that the scraper 120 inserted into the slot 113 forms two extension segments 121. The included angle α between the two groove segments can be consistent with the included angle between the two extension segments 121 of the scraper 120.

[0081] It is understandable that the scraper 120 is a flexible structure. The V-shaped slot 113 allows the flexible scraper 120 to maintain its V-shaped shape, resulting in better cleaning capabilities. The extension direction and shape of the slot 113 are consistent with the aforementioned V-shaped scraper 120, and will not be repeated here.

[0082] For example, the slot 113 may have openings at both ends along its length, allowing the scraper 120 to be inserted from one end of the slot 113. The top of the slot 113 has a notch, and the width of the bottom of the scraper 120 is greater than the width of the notch, allowing the slot 113 to limit the scraper 120 radially along the brush body 110. The top of the scraper 120 extends from the notch, allowing the top of the scraper 120 to contact the surface to be cleaned.

[0083] In some embodiments, at least a portion of the area between the roller brush shaft 111 and the support portion 112 along the axial direction of the roller brush assembly 100 is provided with a ventilation gap 114, thereby forming a channel for airflow in the radial direction of the roller brush and preventing hair fibers from becoming entangled on the roller brush and making it difficult to clean.

[0084] It is understandable that, while ensuring the support strength of the support part 112, opening the ventilation gap 114 can increase the gas flow area, improve the airflow path of the whole machine, and reduce hair entanglement. There can be one or more ventilation gaps 114, and the ventilation gap 114 can be square, circular, prismatic, etc., which are not specifically limited in this application embodiment.

[0085] In some embodiments, the scraper 120 may be integrally formed with the roller brush body 110.

[0086] For example, the support part 112 and the scraper 120 are provided in a one-to-one correspondence, and the number of them can be two, three, four, five or more. This application embodiment does not specifically limit this. Figure 6 The middle section consists of four support parts 112. Figure 7 There are three supporting parts in the middle.

[0087] In some embodiments, the included angle between the radial projections of the two extension segments 121 onto the brush body 110 can be greater than or equal to 162° and less than or equal to 174°. This ensures that the included angle of the two extension segments 121 is within a reasonable range, guaranteeing that the scraper 120 has a better guiding effect on residual waste.

[0088] For example, the specific value of the included angle between the projections of the two extension segments 121 in the radial direction of the brush body 110 can be 162°, 163°, 165°, 170°, 173°, 174°, etc., and this application embodiment does not specifically limit it.

[0089] In some embodiments, the roller brush assembly 100 may include two end caps, which are respectively connected to both ends of the roller brush body 110 in the axial direction. The two ends of the scraper blade 120 abut against the two end caps respectively.

[0090] It should be noted that the two end caps can be connected to both ends of the roller brush body 110 via threads, snap fasteners, etc., and this application embodiment does not make specific limitations.

[0091] Please refer to Figure 1 and Figure 2 This application embodiment also provides a cleaning device 10, which includes a device body 200 and the aforementioned roller brush, with the roller brush rotatably mounted on the device body 200. Through the aforementioned roller brush structure, the cleaning device 10 provided in this application embodiment can clean difficult-to-remove hair fibers from soft surfaces, achieving high cleaning efficiency.

[0092] 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 brush body and multiple scraper strips. The multiple scraper strips are disposed on the roller brush body and are spaced apart around the axial direction of the roller brush body. The scraper strips extend from a first end of the roller brush body along its axial direction to a second end. Each scraper strip includes two extension sections, the ends of which are connected. The projections of the two extension sections in the radial direction of the roller brush body have an included angle, so that the scraper strips protruding from the surface of the roller brush body have a V-shaped structure. Debris remaining between the scraper strips can flow and converge towards the center of the V-shaped structure under the guidance of the scraper strips, thus making it easier to be sucked into the interior of the brush device and enhancing the cleaning ability of the roller brush assembly.

[0093] 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.
