Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and in particular relates to a floor brush and a cleaning device having the floor brush. Background Technology

[0002] Due to transmission and limiting requirements, existing vacuum cleaners and floor scrubbers typically have narrow mounting areas on both sides of the roller brush along its axial direction. Because of these mounting areas, when cleaning wall edges, the tip of the roller brush cannot fully contact the wall, leaving some residue at the edges and preventing proper edge cleaning.

[0003] To achieve edge cleaning, the relevant technology adopts a segmented roller brush design to solve the problem of edge cleaning. The motor bracket is located in the gap between adjacent roller brush segments, and the roller brush segments can be installed from both sides of the motor bracket. This differs from the existing roller brush installation method. The cantilever structure for fixing the roller brush on both sides along the roller brush axis is eliminated, thus enabling edge cleaning of the wall.

[0004] However, due to the gaps between the roller brush sections, there will be residual areas that are not properly cleaned. Summary of the Invention

[0005] Therefore, it is necessary to propose a floor brush and a cleaning device with the floor brush, which can achieve both edge cleaning and seamless cleaning.

[0006] One aspect of this application provides a floor brush, comprising a floor brush body; a roller brush, the roller brush including at least two brush bodies spaced apart and coaxially arranged and a support for supporting the brush bodies, the support being connected to the floor brush body, the brush bodies being rotatably mounted on the support; a drive assembly disposed on the floor brush body for driving the brush bodies to rotate; and a combing mechanism including a combing member disposed on the floor brush body, wherein, in the radial direction of the roller brush, the combing member is located on one side of the roller brush, the combing member corresponds to the gap between adjacent brush bodies, and in the axial direction of the roller brush, the combing member covers the gap.

[0007] In some embodiments, the combing element is rotatably disposed on the brush body, the rotation direction of the combing element is opposite to the rotation direction of the roller brush, and the linear velocity of the contact point between the combing element and the roller brush is greater than the linear velocity of the roller brush; the combing mechanism further includes a combing motor for driving the combing element to rotate.

[0008] In some embodiments, the comb is in the form of a roller or wheel, and the outer circumferential surface of the comb has a textured surface; or the outer circumferential surface of the comb is provided with hard bristles, the hardness of which is greater than that of the bristles on the brush body.

[0009] In some embodiments, the comb is fixedly mounted on the floor brush body.

[0010] In some embodiments, the combing mechanism further includes an elastic support connected to and supporting the combing element of the floor brush body, the elastic support being configured to allow the combing element to radially penetrate into the bristles of an adjacent brush body.

[0011] In some embodiments, the elastic bracket is rotatably connected to the brush body in the direction of brush rotation; or, the elastic bracket is detachably connected to the brush body.

[0012] In some embodiments, a bristle gathering structure is also included, which is connected to the brush body and is positioned corresponding to the gap. The bristle gathering structure and the comb are distributed at intervals around the gap, and the bristle gathering structure is configured to gather the bristles on adjacent brush bodies toward one side of the gap.

[0013] In some embodiments, the bristle gathering structure is located downstream of the comb in the rotation direction of the brush body, so that the momentary contact point between the brush body and the surface to be cleaned passes through the comb and the bristle gathering structure successively during rotation.

[0014] In some embodiments, the bristle gathering structure includes a first guide and a second guide spaced apart along the axial direction of the roller brush, wherein the first guide and the second guide form an axial gap, and the size of the axial gap decreases from the upstream end to the downstream end in the rotational direction of the brush body.

[0015] In some embodiments, the bristle gathering structure radially penetrates into the bristles of the adjacent brush body.

[0016] In some embodiments, the bristle gathering structure is a flexible element; or, the bristle gathering structure is connected to the brush body via a support member, the support member being an elastic element, the support member being configured to allow the bristle gathering structure to radially penetrate into the bristles of the brush body.

[0017] In some embodiments, the floor brush body includes a base and a cover rotatably connected to the base, the cover having an accommodating space, and the roller brush disposed within the accommodating space; the bristle gathering structure is integrally formed or detachably connected to the cover; and / or, the bristle comb is fixedly or rotatably disposed on the base, or fixedly to the cover.

[0018] Another aspect of this application proposes a cleaning device including the floor brush described in any of the above embodiments.

[0019] In this application, by setting a comb to cover the gap between adjacent brush bodies, the bristles at the end of the brush body are combed and loosened when the brush body rotates, so that the bristles stand up and gather to one side of the gap, and maintain a good spread-out state in the gap area. Thus, when the roller brush rotates to contact the surface to be cleaned, the bristles can effectively cover the corresponding area of ​​the gap, and achieve cleaning of the area, solving the problem of cleaning residue caused by the existence of gaps in segmented roller brush floor brushes.

[0036] This application provides a floor brush and a cleaning device incorporating the floor brush. The cleaning device can be a vacuum cleaner, floor scrubber, robotic vacuum cleaner, or other device with floor cleaning functions. The floor brush and cleaning device provided in this application will be described in detail below with reference to their specific structures.

[0037] refer to Figures 1 to 8 An embodiment of the first aspect of this application provides a floor brush 1, including a floor brush body 10, a roller brush 20, a drive assembly 30, and a combing mechanism 40.

[0038] The brush body 10 serves as the basic support structure for the brush 1, supporting and mounting the roller brush 20, drive assembly 30, and combing mechanism 40. For example, see reference... Figure 1 The floor brush body 10 includes a base 110 and a cover 120. The cover 120 is rotatably connected to the base 110. For example, one end of the cover 120 is pivotally connected to the base 110, allowing the cover 120 to be flipped open or closed relative to the base 110. The cover 120 has a receiving space in which the roller brush 20 is disposed. When the cover 120 is closed, the cover 120 and the base 110 together form a space for receiving the roller brush 20; when the cover 120 is open, the user can remove the roller brush 20 for cleaning or replacement. The cover 120 is usually made of transparent material to allow the user to easily observe the operation of the roller brush 20.

[0039] refer to Figures 2 to 4 The roller brush 20 includes at least two brush bodies 210 spaced apart and coaxially arranged, and a support 220 supporting the brush bodies 20. For example, in this embodiment, the roller brush 20 includes two brush bodies 210. The brush bodies 210 are rotatably mounted on the support 220. One end of the support 220 is connected to the base 110 of the brush body 10, and the other end extends between the two brush bodies 210 and is connected to the brush bodies 2210.

[0040] For ease of explanation, Figure 2The brush body 210 on the left is defined as the first brush body, and the brush body 210 on the right is defined as the second brush body. The first and second brush bodies are spaced apart along the axial direction of the roller brush 20. Along the axial direction X of the roller brush 20, the first and second brush bodies are respectively disposed on both sides of the support 220. The brush body 210 includes a roller 211 and bristles 212 disposed on the outer circumferential surface of the roller 211. Specifically, the roller 211 has a cylindrical or cylindrical structure, and bristles 212 are embedded on its outer circumferential surface. The bristles 212 are used to contact the surface to be cleaned when the roller brush 20 rotates, and through the sweeping action, dust and dirt are lifted from the surface to be cleaned or swept into the suction port of the floor brush body 10 (if the cleaning equipment is a vacuum cleaner).

[0041] refer to Figure 1 and Figure 2 The support 220 is connected to the brush body 10 and is used to support the brush body 210 and install the brush body 210 on the brush body 10. In the axial direction X of the roller brush 20, the support 220 is fixedly set at the middle position of the brush body 10.

[0042] refer to Figure 4 The drive assembly 30 is used to drive the brush body 210 to rotate. In this embodiment, the drive assembly 30 is connected to the brush body 10 via a support 220 and is used to drive the brush body 210 to rotate. Specifically, the drive assembly 30 includes a drive motor 310 and a rotating sleeve 320 driven to rotate by the drive motor 310. The brush body 210 of the roller brush 20 is fixedly mounted on the rotating sleeve 320. Each brush body 210 is correspondingly provided with a rotating sleeve 320. The rotating sleeve 320 has a cylindrical structure, and its outer wall is fixedly connected to the inner wall of the roller 211 of the brush body 210. The drive motor 310 is fixed to the support 220 and has two output shafts. The two output shafts extend on both sides of the support 220 in the axial direction X-screw, and each output shaft is connected to a rotating sleeve 320 in a transmission connection.

[0043] Furthermore, the drive motor 310 can also be equipped with an output shaft, which transmits power to the two rotating sleeves 320 respectively through a gear differential or a reverse transmission mechanism. Additionally, the two brush bodies 210 can be driven by two independent drive motors 310. Each brush body 210 corresponds to one drive motor 310 and one rotating sleeve 320, with each drive motor 310 driving the corresponding brush body 210 to rotate. Each drive motor 310 can be independently controlled, enabling the two brush bodies 210 to rotate in the same or opposite directions.

[0044] In another alternative embodiment, the drive assembly 30 is directly mounted on the base 110 of the brush body 10. The drive assembly 30 can also be an external motor that drives the brush body 210 to rotate via a belt or gear. That is, the drive motor 310 is mounted on the base 110 of the brush body 10 and transmits power to the rotation shaft of the brush body 210 via a belt or gear set to achieve power transmission.

[0045] refer to Figures 1 to 4 The combing mechanism 40 includes a combing member 410 disposed on the brush body 10. The combing member 410 is located on one side of the roller brush 20 in the radial direction. The position of the combing member 410 corresponds to the gap 230 between adjacent brush bodies 210, and the combing member 410 covers the gap 230 in the axial direction X of the roller brush 20. In this embodiment, the combing member 410 is configured to loosen the bristles 212 at the ends of adjacent brush bodies 210 during rotation of the roller brush 20, and to bring the bristles 212 together towards the gap 230.

[0046] Specifically, the comb 410 is located above the top of the roller brush 20 (i.e., the end of the floor brush 1 away from the surface to be cleaned when in use). The comb 410 is, for example, generally plate-shaped or comb-tooth-shaped, and its surface facing the brush body 210 may be provided with multiple comb teeth or protrusions. The comb 410 may be made of materials such as hard plastic, metal or ceramic, and its surface facing the brush body 210 is provided with multiple comb teeth, with combing grooves formed between adjacent comb teeth.

[0047] When the brush body 210 rotates, the bristles 212 pass sequentially through the comb member 410, and the comb teeth or protrusions of the comb member 410 insert between the bristles 212. It should be noted that the comb member 410 covering the gap 230 in the axial direction X of the roller brush 20 means that the axial length of the comb member 410 is sufficient to cover the gap 230 between two adjacent brush bodies 210, and the two ends of the comb member 410 in the axial direction X extend to correspond to the ends of the adjacent brush bodies 210, that is, the comb member 410 partially overlaps with the ends of the two brush bodies 210 in the axial direction X.

[0048] In traditional segmented roller brushes, the absence of bristles 212 within the gaps 230 during the rotation of the roller brush 20 results in the ineffective cleaning of the surface corresponding to the area of ​​the gaps 230. Furthermore, the bristles 212 at the ends of adjacent brush bodies 210, lacking support, are prone to lying down or becoming disordered even when tilted towards the gaps 230, further failing to guarantee effective cleaning of the surface corresponding to the area of ​​the gaps 230.

[0049] In this application, by setting the comb 410 to cover the gap 230 between adjacent brush bodies 210, the bristles 212 at the end of the brush body 210 are combed and loosened when the brush body 210 rotates, so that the bristles 212 stand up and gather towards one side of the gap 230, and maintain a good spread-out state in the gap 230 area. It also makes the bristles that have fallen to one side of the gap 230 stand up. Thus, when the roller brush 20 rotates to contact the surface to be cleaned, the bristles 212 can effectively cover the gap 230 area, realize the cleaning of the area, and solve the problem of cleaning residue caused by the existence of gap 230 in segmented roller brushes.

[0050] refer to Figures 2 to 6 In some embodiments, the comb 410 is rotatably mounted on the brush body 10. The comb 410 has, for example, a roller or wheel-like structure. The axis of the comb 410 is arranged parallel to the axis of the roller brush 20. Along the axial direction X, the axial dimension of the comb 410 is configured such that the comb 410 covers the gap 230 between adjacent brush bodies 210.

[0051] The comb component 410 rotates in the opposite direction to the roller brush 20, and the linear velocity at the contact point between the comb component 410 and the roller brush 20 is greater than the linear velocity of the roller brush 20. (Reference) Figure 1 When the roller brush 20 rotates counterclockwise (viewed from the right), the comb 410 rotates clockwise. That is, at the point where the outer circumferential surface of the comb 410 contacts the bristles 212 of the roller brush 20, the linear velocity of the outer circumferential surface of the comb 410 is greater than the linear velocity of the outer circumferential surface of the brush body 210. This results in a greater relative velocity and friction between the comb 410 and the bristles 212. Under the action of the comb 410, the bristles 212 are fully combed and loosened, and hair, dust, and other debris on the bristles 212 are effectively removed.

[0052] The combing mechanism 40 also includes a combing motor 420, which drives the combing component 410 to rotate. The combing motor 420 is fixedly mounted on the brush body 10. The motor shaft of the combing motor 420 is connected to the combing component 410 via a coupling, gear set, or pulley.

[0053] The combing motor 420 can be a DC motor, a stepper motor, or a brushless motor. The rotational speed of the combing motor 420 can be adjusted according to actual needs to control the rotational speed and combing intensity of the combing component 410. For example, the ratio of the linear speed of the combing component 410 to the linear speed of the roller brush 20 can be 1.5-10, which ensures sufficient combing effect while avoiding damage to the bristles 212 due to excessive speed difference.

[0054] This application incorporates an actively rotating combing component 410, with its rotation direction opposite to that of the roller brush 20. Furthermore, the linear velocity of the combing component 410 is greater than that of the roller brush 20. This results in a stronger combing effect on the bristles 212, more effectively removing hair and fibers entangled in the bristles and improving the combing efficiency. Additionally, when the cleaning device is a vacuum cleaner, the floor brush body 10 has a suction port. The active rotation of the combing component 410 can also drive surrounding airflow, helping to draw loosened debris into the suction port and improving cleaning efficiency.

[0055] In other embodiments, the comb 410 is fixedly mounted on the brush body 10.

[0056] Specifically, the comb component 410 can be fixedly installed on the base 110 or cover 120 of the brush body 10 by means of screws, clips, or adhesive. The position of the comb component 410 remains stationary relative to the brush body 10. When the brush body 210 rotates, the bristles 212 on the brush body 210 move relative to the stationary comb component 410, and the comb component 410 combs and loosens the bristles 212.

[0057] The fixed combing component 410 has the advantages of simple structure, low cost, and high reliability. In addition, the fixed combing component 410 requires no additional power during operation, consumes zero energy, has no moving parts, has a low failure rate, and is highly reliable.

[0058] refer to Figure 5 In one embodiment, the outer circumferential surface of the comb 410 is provided with raised and recessed textures 411. The raised and recessed textures 411 provide greater friction between the comb 410 and the bristles 212 of the roller brush 20, thereby improving the combing effect.

[0059] Specifically, the outer circumferential surface of the comb 410 is provided with multiple raised ridges (unmarked) and grooves (unmarked) extending along the axial direction X. The raised ridges and grooves are arranged alternately in the circumferential direction to form a textured pattern 411. The top of the raised ridges can be arc-shaped or flat to reduce or avoid damage to the bristles 212. When the comb 410 rotates, the raised ridges and grooves alternately contact the bristles 212. The raised ridges make the bristles 212 stand up, while the grooves provide space for the bristles 212, thereby loosening and cleaning the bristles 212.

[0060] refer to Figure 6 In another embodiment, the outer circumferential surface of the comb 410 may be provided with hard bristles 412, and the hardness of the hard bristles 412 on the comb 410 is greater than the hardness of the bristles 212 on the brush body 210. When the hard bristles 412 on the comb 410 and the bristles 212 on the brush body 210 come into contact, they interpenetrate each other, and the hard bristles 412 can effectively stand up the bristles 212 of the brush body 210 and gather them together in the gap 230.

[0061] Optionally, the stiff bristles 412 can be made of materials such as nylon, polyester, or metal wire.

[0062] Optionally, the diameter of the stiff bristles 412 is larger than the diameter of the bristles 212 on the brush body 210, and the length of the stiff bristles 412 is shorter than the length of the bristles 212 on the brush body 210. The stiffer, coarser, and shorter bristles 212 on the comb 410 can more effectively insert between the bristles 212 on the brush body 210, causing the bristles 212 to stand up and lift and separate tangled hair, fibers, and other debris. At the same time, when the stiffer bristles 212 contact the bristles 212 on the brush body 210, they generate a certain spring-like effect, causing the bristles 212 to vibrate, which helps to shake off fine dust adhering to the bristles 212. The density of the stiff bristles 412 can be the same as or different from the density of the bristles 212 on the brush body 210. Optionally, the density of the stiff bristles 412 is greater than the density of the bristles 212 on the brush body 210 to improve the combing effect. The stiff bristles 412 can be arranged in a uniform, clustered, or spiral pattern.

[0063] In this application, the wheel-shaped comb 410, by setting concave and convex textures 411 or hard bristles 412, can increase the friction between the comb 410 and the bristles 212 of the roller brush 20, thereby improving the combing effect.

[0064] refer to Figure 1 and Figure 2 In some embodiments, the combing mechanism 40 further includes an elastic support 430. The elastic support 430 is connected to the brush body 10 and supports the comb 410. The elastic support 430 is configured to allow the comb 410 to radially penetrate into the bristles 212 of the adjacent brush body 210.

[0065] Specifically, one end of the elastic bracket 430 is connected to the base 110 of the brush body 10, and the other end supports the comb component 410. The elastic bracket 430 is mounted on the support 220, or it can be directly connected to the base 110. The elastic bracket 430 can be made of metal spring steel, engineering plastics, or rubber elastic materials, and has a certain elastic deformation capability.

[0066] The combing component 410 is fixedly or rotatably mounted on the elastic bracket 430. In the embodiments of this application, the combing component 410 is indirectly supported on the elastic bracket 430 through the combing motor 420, wherein the combing motor 420 and the combing component 410 are located on both sides of the elastic bracket 430, and the motor shaft of the combing motor 420 passes through the elastic bracket 430 and is connected to the combing component 410 for transmission.

[0067] In its natural state, the elastic support 430 is in an extended position, allowing the outer circumferential surface of the comb 410 to radially penetrate into the bristles 212 of the brush body 210 to a certain depth, for example, 1 / 5 to 1 / 2 of the length of the bristles 212. When the brush body 210 rotates, the bristles 212 pass over the comb 410, and the comb 410 is pushed by the bristles 212. The elastic support 430 undergoes elastic deformation, and the comb 410 is slightly pushed away radially, but always maintains a certain pressure on the bristles 212, keeping the comb 410 in a state of penetrating the bristles 212.

[0068] With the above settings, the comb 410 maintains a moderate penetration of the bristles 212 under the action of the elastic support 430, which not only ensures the combing effect, but also avoids damage to the bristles 212 or jamming of the comb 410 due to excessive rigid penetration.

[0069] Further, refer to Figure 1 and Figure 2 In one embodiment, the elastic bracket 430 is configured to be detachably connected to the floor brush body 10. Specifically, the bottom of the elastic bracket 430 is snapped onto the support 220. The elastic bracket 430 can also be detachably connected to the floor brush body 10 via a magnetic or screw structure.

[0070] In this way, users can easily disassemble the combing mechanism 40 for cleaning or replacement as needed, improving the maintenance convenience of the floor brush 1. When the combing component 410 is worn or damaged, only the entire combing mechanism 40 needs to be replaced, without replacing the entire floor brush body 10, thus reducing maintenance costs. In addition, when installing the roller brush 20, users can first disassemble the combing mechanism 40, which facilitates the installation of the roller brush 20.

[0071] In another embodiment, in the rotational direction of the brush body 210, the elastic bracket 430 may be configured to be rotatably connected to the brush body 10.

[0072] Specifically, the elastic support 430 is pivotally connected to the brush body 10, allowing the elastic support 430 to rotate within a certain angle range around the fixed part. The axis of rotation of the elastic support 430 is parallel to the axis of the roller brush 20. A torsion spring may also be provided between the elastic support 430 and the brush body 10. The torsion spring is used to apply a biasing force to the elastic support 430 in the direction of the brush body 210, so that the comb 410 maintains the tendency to penetrate the bristles 212.

[0073] When the comb 410 is subjected to the force of the bristles 212, the elastic support 430 can rotate around the pivot or undergo elastic deformation to adapt to the movement of the bristles 212, thereby reducing the rigid impact between the comb 410 and the bristles 212; and also enabling the comb 410 to better adapt to different states of the bristles 212 (such as length changes caused by different degrees of wear of the bristles 212), and maintain a stable combing effect.

[0074] In this embodiment, an elastic support 430 is provided to support the combing component 410, allowing the combing component 410 to elastically penetrate into the bristles 212, thus achieving flexible combing of the bristles 212. The elastic deformation and rotation function of the elastic support 430 can automatically adapt to changes in the state of the bristles 212, ensuring the combing effect while avoiding excessive damage to the bristles 212 and extending the service life of the roller brush 20.

[0075] refer to Figure 2 , Figure 7 and Figure 8 The floor brush 1 also includes a bristle gathering structure 50. The bristle gathering structure 50 is connected to the floor brush body 10 and its position corresponds to the gap 230. The bristle gathering structure 50 and the combing member 410 are distributed at intervals around the gap 230. The bristle gathering structure 50 is configured to gather the bristles 212 on adjacent brush bodies 210 toward the gap 230.

[0076] Specifically, the bristle gathering structure 50 is positioned on the front side of the roller brush 20 relative to the combing component 410, that is, it is located in the pushing direction when the floor brush 1 is in use (see...). Figure 2 The bristle gathering structure 50 and the bristle comb 410 are spaced at an angle in the circumferential direction around the gap 230. For example, in the circumferential direction of the roller brush 20, the bristle gathering structure 50 is located on the front side of the roller brush 20, and the bristle comb 410 is located above the top of the roller brush 20.

[0077] Furthermore, in the rotation direction of the brush body 210, the bristle gathering structure 50 is located downstream of the combing member 410, so that the instantaneous contact point between the brush body 210 and the surface to be cleaned (such as the ground) passes through the combing member 410 and the bristle gathering structure 50 successively during rotation. Specifically, the roller brush 20 rotates counterclockwise during cleaning (viewed from the right side). After the bristles 212 come into contact with the surface to be cleaned, as the roller brush 20 rotates, the bristles 212 that were originally in contact with the surface to be cleaned first pass through the combing member 410, which combs and loosens the bristles 212; then the bristles 212 continue to rotate and pass through the bristle gathering structure 50, which gathers the bristles 212 on adjacent brush bodies 210 toward the gap 230. In this way, since the area where the gap 230 is located has been fully expanded and gathered with bristles 212, when the bristles 212 come into contact with the surface to be cleaned again, they can effectively cover the area to be cleaned corresponding to the gap 230.

[0078] In this application, a bristle gathering structure 50 is used to gather the bristles 212 at the ends of adjacent brush bodies 210 toward the gap 230, ensuring that the area within the gap 230 is also covered with bristles 212. This more effectively covers the surface to be cleaned corresponding to the gap 230, guaranteeing edge cleaning and eliminating blind spots in the middle. The bristle gathering structure 50 and the combing component 410 are distributed around the gap 230 at intervals. The combing component 410 is responsible for loosening the bristles 212, while the bristle gathering structure 50 is responsible for gathering the loosened bristles 212 toward the gap 230, resulting in more thorough and uniform coverage of the bristles 212 in the gap 230 area. The bristle gathering structure 50 is located downstream of the combing component 410, ensuring that the bristles 212 are loosened before being gathered, resulting in better combing and gathering effects.

[0079] refer to Figure 7 and Figure 8 In one specific implementation of the bristle gathering structure 50, the bristle gathering structure 50 includes a first guide member 510 and a second guide member 520 spaced apart along the axial direction X of the roller brush 20, with a gap 501 formed between the first guide member 510 and the second guide member 520. The first guide member 510 is disposed on the side closer to the first brush body, and the second guide member 520 is disposed on the side closer to the second brush body. The gap 501 is formed between the first guide member 510 and the second guide member 520, and corresponds to the gap 230 between adjacent brush bodies 210. The first guide member 510 and the second guide member 520 can both be arc-shaped plate structures, and their curvature matches the curvature of the outer circumferential surface of the roller brush 20.

[0080] In the rotation direction of the brush body 210, the size of the slit 501 decreases from the upstream end to the downstream end. That is, along the rotation direction of the roller brush 20, the width of the slit 501 gradually decreases, forming a guide structure similar to an inverted "V". The upstream end of the slit 501 (i.e., the end that first contacts the bristles 212) is wider, which facilitates the entry of the bristles 212; the downstream end (i.e., the end that later contacts the bristles 212) is narrower, which causes the bristles 212 to be gradually gathered towards the gap 230 side as they pass through the slit 501.

[0081] Specifically, when the bristles 212 rotate with the brush body 210 and enter the gap 501, the wider entrance end facilitates the entry of the bristles 212. As the brush body 210 rotates, the bristles 212 move within the gap 501. As the gap 501 gradually narrows, the bristles 212 are gradually gathered towards the center (i.e., in the direction of the gap 230).

[0082] Optionally, the surfaces of the first guide 510 and the second guide 520 facing the brush body 210 are smooth, arc-shaped surfaces to reduce friction with the bristles 212 and prevent damage to the bristles 212 during the gathering process. The first guide 510 and the second guide 520 can be made of self-lubricating materials, such as polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMWPE), etc., or have a lubricating coating applied to their surfaces.

[0083] In another specific implementation of the bristle gathering structure 50, the surface of the bristle gathering structure 50 facing the roller brush 20 is provided with a guide groove. The upstream end of the guide groove is wider to facilitate the entry of the bristles 212; the downstream end is narrower so that the bristles 212 are gradually gathered towards the gap 230 side when passing through the guide groove.

[0084] In some embodiments, the bristle gathering structure 50 radially penetrates into the bristles 212 of the adjacent brush body 210. Specifically, the surfaces of the first guide 510 and the second guide 520 facing the brush body 210 extend radially into the bristles 212 of the brush body 210 to a certain depth. In this way, the bristles 212 can reliably enter the gap 501 between the first guide 510 and the second guide 520 during rotation, and be guided and gathered by the first guide 510 and the second guide 520.

[0085] The penetration depth is, for example, 1 / 5 to 1 / 2 of the length of the bristles 212. This ensures that the bristles 212 effectively enter the gap 501 and maintain the gathering effect. On the other hand, it prevents the bristles 212 from bending excessively or even breaking, and also reduces the rotational resistance of the roller brush 20 caused by penetration.

[0086] In this application, the bristle gathering structure 50 is connected to the brush body 10 via a support member 530, which is an elastic member. The support member 530 is configured to allow the bristle gathering structure 50 to radially penetrate into the bristles 212 of the brush body 210.

[0087] Specifically, refer to Figure 7 and Figure 8 The support member 530 is snapped onto the bottom edge of the cover 120; the bristle gathering structure 50 includes a first guide member 510 and a second guide member 520, which are disposed on the surface of the support member 530 facing the roller brush 20.

[0088] In its natural state, the support member 530 presses the bristle-gathering structure 50 against the brush body 210, causing the bristle-gathering structure 50 to penetrate a certain depth into the bristles 212. When the bristles 212 pass by, the bristles 212 generate a reaction force on the bristle-gathering structure 50, causing the support member 530 to undergo elastic deformation. The bristle-gathering structure 50 is slightly pushed away by the bristles 212, thus avoiding rigid impact. Furthermore, the elasticity of the support member 530 ensures that the bristle-gathering structure 50 maintains appropriate contact pressure with the bristles 212 at all times, guaranteeing an effective gathering effect even when the bristles 212 wear and shorten.

[0089] In other embodiments, the bristle gathering structure 50 can be a flexible component. Specifically, the first guide 510 and the second guide 520 are both made of flexible materials such as silicone or rubber. When the brush body 210 rotates, the flexible component undergoes elastic deformation, thus reducing the damage to the bristles 212 caused by the bristle gathering structure 50 and enabling it to automatically adapt to changes in the state of the bristles 212.

[0090] In this application, references Figure 1 The floor brush body 10 includes a base 110 and a cover 120. The cover 120 is rotatably connected to the base 110. One end of the cover 120 is pivotally connected to the base 110 via a pivot, allowing the cover 120 to be flipped open or closed relative to the base 110. The cover 120 has a receiving space, within which the roller brush 20 is disposed.

[0091] In this application, the bristle gathering structure 50 and the bristle comb 410 can be implemented in several different ways.

[0092] For example, refer to Figure 7 The bristle gathering structure 50 is integrally formed or detachably connected to the cover 120. The bristle gathering structure 50 is specifically provided on the inner wall of the cover 120, that is, on the surface of the cover 120 facing the roller brush 20.

[0093] Specifically, the bristle gathering structure 50 is detachably connected to the cover 120. The bristle gathering structure 50 is mounted on a support member 530, which is snapped into the lower edge of the cover 120. The support member 530 is specifically a plate-shaped structure, fixedly connected to or integrally formed with the bristle gathering structure 50. The lower end of the support member 530 has a hook 531, which snaps into the lower edge of the cover 120. Alternatively, the bristle gathering structure 50 can be detachably mounted to the inner wall of the cover 120 using screws, magnetic structures, or other fixing methods.

[0094] The detachable connection makes it easier to clean and replace the bristle gathering structure 50. Users can periodically remove the bristle gathering structure 50 for cleaning as needed to maintain its cleanliness and gathering effect.

[0095] In other embodiments, the bristle gathering structure 50, such as the first guide 510 and the second guide 520, is integrally formed on the inner wall of the cover 120.

[0096] In this application, the bristle gathering structure 50 is provided on the cover 120. When the cover 120 is opened, the bristle gathering structure 50 opens together with the cover 120. The removal and installation of the roller brush 20 are not hindered by the bristle gathering structure 50, which facilitates the user's maintenance and operation of the roller brush 1.

[0097] The comb 410 can be configured to be rotatably mounted on the base 110 or fixed to the cover 120.

[0098] refer to Figure 2 and Figure 4 The combing component 410 is rotatably mounted on the base 110. Specifically, an elastic bracket 430 is connected to the base 110, and both the combing component 410 and the combing motor 420 are mounted on the elastic bracket 430. The combing motor 420 is fixed to the elastic bracket 430, and the combing component 410 is sleeved on the motor shaft of the combing motor 420. In other embodiments, the combing component 410 is fixedly mounted on the base 110. For example, the combing component 410 is fixedly mounted on the base 110 by screws and is located above the roller brush 20.

[0099] When the cover 120 is closed, the combing component 410 and the bristle gathering structure 50 are arranged at intervals around the gap 230 in the rotation direction of the roller brush 20. The combing component 410 is set on the base 110, which ensures the positional stability of the combing component 410 during operation and helps to improve the combing effect.

[0100] Furthermore, the comb component 410 can also be fixed to the cover 120. In this case, the comb component 410 and the cover 120 can be integrally formed or installed on the cover 120 through a fixed connection, and flip together with the cover 120. The solution of fixing the comb component 410 to the cover 120 makes the structure simpler, and when the cover 120 is opened, the comb component 410 is moved away with the cover 120, making it more convenient to remove and install the roller brush 20.

[0101] An embodiment of the second aspect of this application provides a cleaning device, including a floor brush 1 with any of the structures described above. This cleaning device can be a vacuum cleaner, a floor scrubber, a robotic vacuum cleaner, etc.

[0102] Taking a vacuum cleaner as an example, the vacuum cleaner includes a floor brush 1, a vacuum cleaner body, and a connecting pipe connecting the floor brush 1 and the vacuum cleaner body. The floor brush 1 is connected to the vacuum cleaner body through the connecting pipe, and the vacuum cleaner body is equipped with a fan and a dust collection unit. During operation, the fan generates negative pressure, sucking dust and debris into the suction port of the floor brush 1, which then enters the dust collection unit inside the vacuum cleaner body through the connecting pipe. The roller brush 20 of the floor brush 1 rotates under the drive of the drive assembly 30, sweeping and cleaning the floor. The combing mechanism 40 combs and loosens the bristles 212 of the roller brush 20, and the bristle gathering structure 50 gathers the bristles 212 into the gaps 230, enabling the floor brush 1 to achieve efficient edge cleaning without any blind spots in the middle.

[0103] Taking a floor scrubber as an example, this floor scrubber includes a floor brush 1, a machine body, a clean water tank, and a wastewater tank. The floor brush 1 is located at the bottom of the machine body and is equipped with a water spraying device inside for spraying clean water or cleaning solution onto the surface to be cleaned. The roller brush 20 performs wet cleaning of the floor while rotating, and the bristles 212 brush up the dirt on the floor, while the wastewater is sucked into the wastewater tank. The bristle combing mechanism 40 and the bristle gathering structure 50 enable the roller brush 20 to maintain its self-cleaning ability during the cleaning process, preventing hair and debris from getting tangled on the bristles 212, thus improving the cleaning effect and user experience.

[0104] Taking a robotic vacuum cleaner as an example, the robotic vacuum cleaner includes a floor brush 1, a robot body, wheels, and a control system. The floor brush 1 is located at the bottom of the robot body, and the roller brush 20 rotates under the drive of the drive component 30 to automatically clean the floor. The combing mechanism 40 and the bristle gathering structure 50 enable the robotic vacuum cleaner to clean along the edges of walls, avoiding residue in corners.

[0105] The cleaning device of this application, by employing the aforementioned floor brush 1, solves the problem of cleaning residue caused by the gaps between brush segments in existing segmented roller brushes by setting a combing mechanism 40 and a bristle gathering structure 50 at corresponding positions in the gaps 230 between adjacent brush bodies 210. This achieves edge cleaning without any blind spots in the middle. Simultaneously, the combing mechanism 40's combing action on the bristles 212 gives the roller brush 20 a self-cleaning ability, reduces hair tangling, extends the service life of the roller brush 20, and improves cleaning effect and user experience.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
