In actual use, the roller brush can easily become entangled in filamentous objects, such as hair, fibers, or string, especially hair. This accumulation of entangled objects can eventually cause the roller brush to become stuck or malfunction, affecting its cleaning performance. Utility Model Content

[0003] In view of this, the present application is dedicated to providing a roller brush to solve the problem in the prior art that the roller brush is easily stuck or jammed due to the accumulation of entanglements such as hair, which affects cleaning.

[0004] On one hand, the present application provides a roller brush, comprising a roller and a brush strip arranged on the roller; a groove is provided on a local section of the roller, the groove extending along the circumference of the roller and forming a collection area recessed in the surface of the roller;

[0005] The collecting area divides the brush strips into at least two groups in the axial direction of the roller. The at least two groups include a first brush strip group and a second brush strip group. Both the first brush strip group and the second brush strip group have a rotation angle in the circumferential direction of the roller so as to push the filaments wound on the roller brush to the collecting area when the roller rotates.

[0006] In a possible embodiment, the collection area is provided with a middle section located in the axial direction of the drum, and the first brush bar group and the second brush bar group are located on both sides of the collection area in the axial direction and have opposite rotation directions.

[0007] In a possible embodiment, the roller includes a first barrel section and a second barrel section arranged in the axial direction, and the first brush bar group and the second brush bar group are respectively located on the first barrel section and the second barrel section; a contraction section with a reduced diameter protrudes from the end of any one of the first barrel section and the second barrel section, and the contraction section is detachably connected to the other to form the collection area.

[0008] In a possible implementation manner, the diameter of the contraction section gradually decreases in a direction approaching the other one to form a frustum shape.

[0009] In a possible implementation manner, the contraction section is plugged into the other one, and the other one is provided with a plug-in groove for partially embedding the contraction section.

[0010] In a possible embodiment, the first brush strip group includes a first bristle brush and / or a first rubber brush arranged at intervals along the circumferential direction, and the second brush strip group includes a second bristle brush and / or a second rubber brush arranged at intervals along the circumferential direction; wherein, the extension angle of the first bristle brush and the second bristle brush in the circumferential direction of the roller is 90 degrees to 100 degrees, and the extension angle of the first rubber brush and the second rubber brush in the circumferential direction of the roller is 100 degrees to 120 degrees.

[0028] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0029] Please refer to the attached Figure 1-7The embodiment of the present application provides a roll brush capable of being used for cleaning, the roll brush comprising a roller and brush strips arranged on the roller, the roller being used for being connected with rotation of a device body and rotating around an own axis relative to the body. If the device body has a power element such as a motor, the roller can also be connected with the power element. The brush strips are arranged on the roller and protrude from the surface of the roller, are strip-shaped and are arranged in an interval along the circumferential direction of the roller and extend in a spiral or rotation along the axial direction of the roller, can be a hair brush formed by hair bundles or a rubber brush formed by rubber sheets or are alternately arranged with the hair brush and the rubber brush. When the roll brush is arranged on a cleaning device such as a sweeper, the roll brush moves with the body, and the roller rotates with the brush strips under the power element, the brush strips arranged in rotation slide relative to the surface to be cleaned such as the ground, and have a pushing effect on the objects to be cleaned such as hair and debris. Meanwhile, in the present application, grooves are formed on the local sections of the roller, the grooves extend along the circumferential direction of the roller and form collection areas 101; the collection areas 101 are provided with at least one and separate the brush strips into at least two groups in the axial direction of the roller, the at least two groups of brush strips comprise a first brush strip group and a second brush strip group located on both sides of a certain collection area 101, and the first brush strip group and the second brush strip group both have a rotation angle in the circumferential direction of the roller; when the first brush strip group and the second brush strip group rotate with the roller, they both push the objects to be cleaned to the collection area 101. Meanwhile, since the collection area 101 is recessed from the brush strips and the surface of the roller, when the objects to be cleaned have hair, fibers and other filamentous objects, the hair and other filamentous objects can be pushed to the collection area 101 and fall into and accumulate in the collection area 101, and cannot be wound on the brush strips. Therefore, during cleaning, when the brush strips push the hair, debris and other objects, if the body is provided with a dust suction assembly, the debris, dust and other objects can be directly sucked away by the dust suction port, the hair, fibers and other filamentous objects that are not sucked away can be directly pushed by the brush strips into the collection area 101, even if part of them is wound on the brush strips, they can also be pushed into the collection area 101 recessed from the brush strips and the surface of the roller and separated from the brush strips and accumulated in the collection area 101, so that the amount of filamentous objects wound on the brush strips can be effectively reduced, the problem of affecting the cleaning efficiency caused by the filamentous objects wound on the brush strips can be effectively prevented, and the phenomenon of the roll brush being stuck or dead caused by too much winding can also be prevented.

[0030] It can be seen that the roll brush provided by the present application is suitable for being used on a cleaning device to clean and can effectively collect hair, fibers and other filamentous objects and effectively prevent the problem of affecting the cleaning efficiency caused by the filamentous objects wound on the brush strips, and is especially suitable for being used on a household cleaning device such as a sweeper. Since there are more hair falling in a house, the problem of the roll brush being wound and affecting the cleaning and needing frequent manual cleaning of the roll brush on the cleaning device such as the sweeper can be effectively solved by the roll brush provided by the present application, the cleaning efficiency is improved, the frequency of manual cleaning of the hair on the roll brush is reduced, and the use performance is improved.

[0031] The roller brush may be provided with one, two, or more collection areas 101. When there is only one collection area 101, the first and second brush bar groups are located on opposite axial sides of the collection area 101 and rotate in opposite directions. Thus, when the roller rotates, the first and second brush bar groups push the objects to be cleaned into the collection area 101. When there are two collection areas 101, for example, located at either end of the roller, or one at the end and one in the middle of the roller, the first and second brush bar groups each correspond to a collection area 101 and are located on one axial side of the corresponding collection area 101. In such embodiments, the rotational directions of the first and second brush bar groups may be consistent or inconsistent, depending on the positions of the two collection areas 101. When the roller brush is provided with multiple axially arranged collection areas 101, the brush bars are also divided into multiple groups along the axial direction. One group or two groups located on either side of the same collection area 101 correspond to one collection area 101.

[0032] In a preferred embodiment, as shown in the accompanying drawings, only one collection area 101 is provided on the drum. This collection area 101 can be located in the middle section of the drum in the axial direction. The first and second brush bar groups are located on either side of the collection area 101 in opposite directions and can be arranged symmetrically. This not only solves the entanglement problem, but also simplifies the structure and facilitates production. Furthermore, hair and other debris are stored in the same collection area 101, making it easier to clean.

[0033] Furthermore, in a preferred embodiment, the roller includes a first barrel section 1 and a second barrel section 7 arranged in the axial direction, a first brush bar group is provided on the first barrel section 1, and a second brush bar group is provided on the second barrel section 7. A contraction section 9 with a reduced diameter protrudes from the end of either the first barrel section 1 or the second barrel section 7. The contraction section 9 is detachably connected to the other barrel section and forms a groove-shaped collection area 101, that is, one end of the contraction section 9 is connected to a barrel section (which may be an integrated structure), and the other end is inserted into the insertion groove of the other barrel section. The area between the two ends of the contraction section 9 forms a collection area 101 recessed in the surface of the roller. In this way, when a large amount of hair and other garbage accumulates in the collection area 101, the roller brush can be removed from the body and the two barrel sections can be directly disassembled to very conveniently and thoroughly clean the hair and other garbage in the collection area 101.

[0034] For example, the contraction section 9 is plugged into another, and the other is provided with a plug-in slot for the partial insertion of the contraction section 9. In this way, the two barrel sections can be assembled by simply docking and plugging together, making assembly and disassembly convenient. Of course, in other embodiments, the two barrel sections can also be connected by fasteners.

[0035] like Figure 2As shown, in some embodiments, the diameter of the constricted section 9 gradually decreases toward the disassembly connection, forming a frustum. This configuration allows the constricted section 9 to have a thick end and a thin end. When the first barrel section 1 and the second barrel section 7 are separated, hair and other objects entangled in the constricted section 9 can be directly removed from the thin end, making it very convenient and thorough to clean hair and other entangled objects.

[0036] The two barrel sections can be connected to two power members such as two motors respectively, or the two can be linked and driven by only one power member. For example, a circumferential anti-rotation structure is provided between the first barrel section 1 and the second barrel section 7, so that one can drive the other to rotate synchronously. The circumferential anti-rotation structure may include a connecting column 4, which is connected to one of the first barrel section 1 and the second barrel section 7 and can be detachably connected to the other, and the cross-section of at least a partial section of the connecting column 4 is a non-circular shape with edges or protrusions, such as a triangle, a quadrilateral, a hexagon, etc., or there are protrusions on the column such as splines. In this way, not only can the two barrel sections be linked synchronously, but also the disassembly of the two barrel sections to clean the garbage in the collection area 101 will not be affected.

[0037] The connecting column 4 can be inserted into the contraction section 9. For example, in a specific embodiment, Figure 3 and Figure 6 As shown, the contraction section 9 is located on the second barrel section 7, and the insertion slot is located on the first barrel section 1. The connecting post 4 can be connected to the second barrel section 7, extending from the end of the contraction section 9 and inserted into the first barrel section 1, with a first groove for the connecting post 4 being inserted into the bottom wall of the insertion slot of the first barrel section 1. Alternatively, the connecting post 4 can be connected to the first barrel section 1 and removably connected to the contraction section 9 and the second barrel section 7, with the main body of the contraction section 9 and the second barrel section 7 having a second groove for the connecting post 4. Alternatively, the connecting post 4 can be removably connected to both the first barrel section 1 and the second barrel section 7, with a first groove for the connecting post 4 being inserted into the bottom wall of the insertion slot, and a second groove for the connecting post 4 being inserted into the main body of the contraction section 9 and the second barrel section 7. This arrangement facilitates the removal of hair and other entanglements entangled in the contraction section 9 during disassembly.

[0038] In some other embodiments, the cross-section of the contraction section 9 may be non-circular, forming the above-mentioned connecting column 4, which plays a circumferential anti-rotation role and enables the two barrel sections to be synchronously linked.

[0039] One end of the roller brush has a rotating shaft 8, which can be inserted into the sliding bearing on the body, and the other end can be a swivel joint such as a square male head, which is inserted into the corresponding joint of the driving mechanism such as a square female head and is connected to the power part.

[0040] The first brush strip group includes a plurality of first brushes 3 or a plurality of first rubber brushes 2 spaced circumferentially, or a plurality of first brushes 3 and first rubber brushes 2 interlaced in sequence. Similarly, the second brush strip group includes a plurality of second brushes 5 or a plurality of second rubber brushes 6 spaced circumferentially, or a plurality of second brushes 5 and second rubber brushes 6 interlaced in sequence. The first brush strip group and the second brush strip group may be symmetrically arranged. When both are provided with brushes and rubber brushes, the first brushes 3 and the second brushes 5 are symmetrically arranged, and the first rubber brushes 2 and the second rubber brushes 6 are symmetrically arranged.

[0041] In a preferred embodiment, the first brush strip assembly includes a first fur brush 3 and a first rubber brush 2, spaced and interlaced along the circumference of the drum. The second brush strip assembly includes a second fur brush 5 and a second rubber brush 6, spaced and interlaced along the circumference of the drum. The height of the first fur brush 3 and the second rubber brush 5 (the dimension extending radially from the drum surface) is slightly greater than that of the first rubber brush 2 and the second rubber brush 6, for example, 2 mm.

[0042] The brush and the rubber brush may be arranged in a spiral shape, or, in some embodiments, as shown in the attached Figure 4 As shown, the first brush 3 and the second brush 5 extend at an angle α1 in the circumferential direction of the drum, 90°≤α1≤110°, preferably 10°. The first rubber brush 2 and the second rubber brush 6 extend at an angle α2 in the circumferential direction of the drum, 100°≤α2≤120°, preferably 110°. In this way, the brushes and rubber brushes are not arranged in a spiral shape, but instead wrap around the drum in a small half circle rather than a full circle. Combined with the symmetrical arrangement of the two groups of brushes, the two groups of rubber brushes form a V-shape as a whole. This V-shape has a good pushing and gathering effect during cleaning, and can very effectively push the cleaned garbage and other objects to the central collection area 101, enhancing the cleaning effect.

[0043] In some embodiments, the first brush 3 and the second brush 5 are symmetrically arranged on both sides of the collecting area 101, and the hair bundles in the first brush 3 and the hair bundles in the second brush 5 are inclined toward the collecting area 101 in the axial direction of the drum, such as Figure 1 and Figure 2 As shown, the inclination angle between the bristle bundle and the drum surface is β, and the range of β can be 40°≤β≤50°, and specifically can be any angle within this range, such as 42°, 45°, 48°50°, etc. This arrangement can enhance the effect of pushing and gathering the cleaned objects to the collection area 101 between the two groups of brushes, and reduce the pushing resistance.

[0044] Furthermore, in some embodiments, Figure 1 and Figure 2As shown, the first brush 3 and the second brush 5 intersect at the top corner area near one end of the collection area 101. This ensures that the brushes are not discontinuous in the axial direction of the drum, improving coverage and preventing missed areas during cleaning. Furthermore, only the top corners at the ends intersect, resulting in a smaller intersection area. When hair and other objects are pushed there, the force applied allows them to pass through the intersection area and fall into the collection area 101, rather than being blocked outside the collection area 101.

[0045] In some embodiments, the first and second rubber brushes 2 and 6 are provided with a guide bevel 102 inclined toward the collection area 101 at one end near the collection area 101. The guide bevel 102 can be located at the top corner of the end, formed by a missing top corner of the rubber brush or a guide bevel, connecting the top edge of the rubber brush with the side edge of the rubber brush. This arrangement not only enhances the shedding of entangled objects from the rubber brushes and bristles into the collection area 101, but also prevents excessive rubber brush loss that could affect cleaning.

[0046] An embodiment of the present application also provides a cleaning machine, on the body of which a roller brush is provided. The roller brush is the roller brush described in any of the above embodiments. In this way, the cleaning machine has the beneficial effects of the above roller brush, such as not being easily entangled by hair, which will not be repeated here.

[0047] The cleaning machine may specifically be a sweeping machine or the like.
