[0003] In the relevant art, a cleaning device comprises a device body and a floor brush structure. The floor brush structure is arranged at one end of the device body for direct contact with a surface to be cleaned. The floor brush structure usually comprises a floor brush body and a roller brush assembly. Two ends of the roller brush assembly are directly and indirectly rotatably connected to the floor brush body through which the roller brush assembly is driven to rotate, and stability of the rotation of the roller brush assembly is ensured.

[0004] However, when the roller brush assembly rotates, hair, which is difficult to handle, will be entangled at an end of the roller brush assembly, affecting the cleaning efficiency of the cleaning device and shortening the service life of the cleaning device.

[0005] Based on this, the present application provides a floor brush structure and a cleaning device to reduce hair entanglement on a roller brush assembly, improve the cleaning efficiency of the cleaning device, and extend the service life of the cleaning device.

[0013] In this way, the rotating assembly can realize rotatable cooperation between the cutting assembly and the roller brush assembly, so that when hair is entangled into the roller brush assembly, the hair is cut by the relative rotation between the cutting assembly and the roller brush assembly, thereby improving hair cutting efficiency.

[0014] In a possible implementation, in the floor brush structure provided by the present application, the floor brush body comprises a housing and a driving member, the housing having a mounting chamber adapted to the roller brush assembly, the driving member being located in the mounting chamber, the mounting chamber having an opening at an end away from the driving member, the roller brush assembly being inserted into the mounting chamber through the opening and connected to the driving member, the driving member being configured to drive the roller brush assembly to rotate around its axis.

[0015] In this way, the driving member can be used to drive the roller brush assembly to rotate, ensuring that the cleaning device can efficiently and easily perform cleaning work, and the housing can be used to provide safety protection for the roller brush assembly and the driving member, ensuring that the roller brush assembly and the driving member can operate normally and extending the service life of the cleaning device.

[0016] In a possible implementation, in the floor brush structure provided by the present application, the connecting assembly comprises a first connecting shaft, the handle assembly comprises a handle body, and the cutting assembly comprises a fixing frame, the first connecting shaft being inserted into the handle body and the fixing frame.

[0017] In this way, by connecting the handle body to the fixing frame through the first connecting shaft, the connection between the handle body and the fixing frame can be made stable and reliable. When necessary, the handle body and the fixing frame can cooperate in a swingable manner relative to the first connecting shaft, so that the connection between the handle body and the fixing frame is flexible and subsequent assembly and disassembly of the handle assembly is facilitated.

[0018] In a possible implementation, in the floor brush structure provided by the present application, the handle body is provided with a first connecting hole, and the fixing frame is provided with a second connecting hole, the first connecting shaft being inserted into the first connecting hole and the second connecting hole.

[0019] In this way, by providing connecting holes for inserting the first connecting shaft respectively on the handle body and the fixing frame, assembly and disassembly of the first connecting shaft can be made more convenient and quicker.

[0020] In a possible implementation, in the floor brush structure provided by the present application, the connecting assembly further comprises a reset member sleeved on the first connecting shaft and abutting against the handle body and the fixing frame respectively.

[0021] In this way, by sleeving the reset member, which abuts against the handle body and the fixing frame, on the first connecting shaft, the relative position between the handle body and the fixing frame can be maintained by the reset member when there is no external force between the handle body and the fixing frame, thereby ensuring that the connection between the handle assembly and the cutting assembly is more stable and reliable, and making it more convenient to use.

[0022] In a possible implementation, in the floor brush structure provided by the present application, the handle assembly further comprises a snap-fit member located on the handle body and configured to snap fit or disengage from snap-fit with the floor brush body.

[0023] In this way, by snap-fit or disengagement from snap-fit between the snap-fit member and the floor brush body, the handle assembly, the cutting assembly, and the roller brush assembly can be detachably connected to the floor brush body, so that assembly and disassembly of the floor brush structure is convenient and efficient.

[0024] In a possible implementation, in the floor brush structure provided by the present application, the rotating assembly comprises a rotary bearing and a second connecting shaft, the rotary bearing having an outer ring and an inner ring that rotatably cooperate with each other, the outer ring being fixedly connected to the cutting assembly, one end of the second connecting shaft being fixedly inserted in the inner ring, and the other end of the second connecting shaft being coaxially inserted to the roller brush assembly.

[0025] In this way, relative rotatable cooperation between the cutting assembly and the roller brush assembly is achieved through the rotary bearing and the second connecting shaft, which makes the roller brush assembly rotate smoothly and stably with little noise and a long service life.

[0026] In a possible implementation, in the floor brush structure provided by the present application, the rotating assembly further comprises a retaining ring member located in the cutting assembly and snap fitted with the outer ring.

[0027] In this way, detachable connection between the cutting assembly and the rotary bearing is achieved by providing the retaining ring member, which facilitates subsequent assembly, disassembly and maintenance of the rotating assembly, making it more convenient and flexible to use.

[0028] In a possible implementation, in the floor brush structure provided by the present application, the cutting assembly further comprises at least one blade, and the fixing frame has a mounting groove with an opening facing the inner side wall, the blade being located in the mounting groove with a cutting edge of the blade facing the opening of the mounting groove.

[0029] In this way, by arranging the blade in the opening of the mounting groove facing the inner side wall of the accommodating groove, and orienting the cutting edge towards the opening, when hair is entangled into the gap, the cutting edge can first come into contact with the hair, and cut the hair when the hair is further entangled. With the blade located in the mounting groove, the safety protection performance of the cutting assembly can be improved, and cutting a user can be prevented.

[0030] In a possible implementation, in the floor brush structure provided by the present application, there are at least two of the blades and they are arranged in a spaced apart manner in the mounting groove.

[0031] In this way, arranging a plurality of blades in a spaced apart manner can improve the efficiency of cutting hair, and facilitate cutting hair into short segments, which further reduces the possibility of hair entanglement.

[0032] In a possible implementation, in the floor brush structure provided by the present application, the cutting edge is lower than the opening of the mounting groove.

[0033] In this way, the protective performance of the cutting assembly can be further enhanced, so that the blade can only act on hair or other objects entering the mounting groove, preventing a user from being accidentally injured when the user assembles, disassembles or cleans the cutting assembly.

[0034] In a possible implementation, in the floor brush structure provided by the present application, the fixing frame is at least partially exposed outside the accommodating groove, the part of the fixing frame exposed outside the accommodating groove forming a guide opening of the gap with the accommodating groove.

[0035] In this way, since the fixing frame is relatively located at an inner side of the accommodating groove and is exposed outside the accommodating groove to form the guide opening, the guide opening can be used to guide the movement of hair to enter the gap through the guide opening and be cut by the cutting assembly, thereby improving the cutting efficiency of the cutting assembly and thus reducing the possibility of hair entanglement on the roller brush assembly.

[0036] In a possible implementation, in the floor brush structure provided in the present application, the roller brush assembly comprises a drum and an end cover covering an end of the drum, the accommodating groove being located in the end cover.

[0037] In this way, by arranging the drum and the end cover to form the roller brush assembly together and arranging the accommodating groove in the end cover, the structure of the roller brush assembly can be made simpler and more compact, facilitating subsequent maintenance and cleaning.

[0038] In another aspect, the present application further provides a cleaning device comprising a device body and any one of the floor brush structures described above, the floor brush structure being connected to the device body.

Detailed description of embodiments

[0042] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar components or components with the same or similar functions.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0043] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "mount", "connect" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, or indirect connection through an intermediate medium, or internal communication between two elements or an interaction relationship between two elements. For those skilled in the art, specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0044] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate orientation or position relationships based on the drawings, which are only for the convenience of describing the present application and simplifying the description, do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application.

[0045] The terms "first", "second", "third" (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented, for example, in an order other than those illustrated or described herein.

[0046] In addition, the terms "comprise and "have" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or display comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or displays.

[0047] As mentioned in the "background" section, a cleaning device comprises a device body and a floor brush structure. The device body, as a core part of the cleaning device, generally comprises a host, a handle, a control device, a dust cup, a water tank, etc., so as to ensure that the cleaning device operates efficiently and stably. The floor brush structure is arranged at an end of the device body and is detachably connected to the device body. Specifically, it is located at an end of the cleaning device facing a floor when the cleaning device is in an operating position, so as to come into direct contact with the floor during use and clean it. After cleaning, the floor brush structure can be detached for cleaning and maintenance.

[0048] The floor brush structure usually comprises a floor brush body and a roller brush assembly. Two ends of the roller brush assembly are connected to the floor brush body, and it can be driven by a driving member of the floor brush body to rotate around its own axis so as to clean a floor.

[0049] However, in actual use, when there is hair on a floor to be cleaned, as the roller brush assembly rotates, the hair will be entangled to an end of the roller brush assembly, which is difficult to deal with, thereby hampering smooth rotation of the roller brush assembly, affecting the cleaning efficiency of the cleaning device, shortening the service life of the cleaning device, or even causing damage to the device.

[0050] In view of the above problem, the present application provides a floor brush structure and a cleaning device, which, by providing a cutting assembly at an end of the roller brush assembly to cut hair when the hair is rolled in at the rotation axis of the roller brush assembly, improve the cleaning efficiency of the cleaning device and extend its service life.

[0051] Specific modes of realization of the floor brush structure and cleaning device provided by embodiments of the present application are described below in detail in conjunction with Figures 1 to 8.

[0052] In reference to Figures 1 to 3, a floor brush structure provided by an embodiment of the present application comprises a floor brush body 100, at least one roller brush assembly 200 and at least one cutting assembly 300. An end of the roller brush assembly 200 has an accommodating groove 221 in which the cutting assembly 300 is correspondingly located. The roller brush assembly 200 is rotatably connected to the floor brush body 100 through the cutting assembly 300.

[0053] The cutting assembly 300 is configured to form a gap 222 with an inner side wall of the accommodating groove 221, and when hair is rolled into the gap 222 by the roller brush assembly 200 and entangled on the cutting assembly 300, cut the hair.

[0054] It can be understood that the floor brush body 100 is provided with a plug-in port, which can be connected to a device body during use.

[0055] At least one roller brush assembly 200 is rotatably connected to the floor brush body 100, and the axis of the roller brush assembly 200 is perpendicular to the movement direction of the floor brush body 100 in daily use and parallel to a surface to be cleaned, so that a user can push and pull the cleaning device more easily when the roller brush assembly 200 rotates.

[0056] Specifically, an end of the roller brush assembly 200 is transmission-connected to the floor brush body 100, so that the floor brush body 100 can drive the roller brush assembly 200 to rotate. The other end of the roller brush assembly 200 is provided with the accommodating groove 221, so that the cutting assembly 300 can be mounted in the accommodating groove 221, and the end of the roller brush assembly 200 is rotatably connected to the floor brush body 100 through the cutting assembly 300. Hence, two ends of the roller brush assembly 200 can both rotate relative to the floor brush body 100.

[0057] The cutting assembly 300 and the inner side wall of the accommodating groove 221 are clearance fitted with the gap 222. Thus, the gap 222 can be formed between the cutting assembly 300 and the inner side wall of the accommodating groove 221, and during the rotation of the roller brush assembly 200, hair will be gradually rolled into the gap 222 as the roller brush assembly 200 rotates and tend to further tightly entangle toward the cutting assembly 300 in the accommodating groove 221. As the hair becomes further entangled, the interaction force between the hair and the cutting assembly 300 will increase, so that the hair is subjected to a force and cut by the cutting assembly 30. After the hair is cut, it will be difficult for it to become further entangled and thus will not hamper the rotation of the roller brush assembly 200. Instead, it will continue to accumulate in the accommodating groove 221, for a user to remove it after cleaning, or naturally fall off on the surface to be cleaned and then cleaned by the cleaning device.

[0058] Thus, in the floor brush structure provided by the embodiment of the present application, by arranging the cutting assembly 300 in the accommodating groove 221 of the roller brush assembly 200, the roller brush assembly 200 is rotatably connected to the floor brush body 100 through the cutting assembly 300, so that when hair is rolled into the gap 222 between the roller brush assembly 200 and the cutting assembly 300, it is cut by the cutting assembly 300, thereby preventing the hair from continuing to be entangled on the roller brush assembly 200.

[0059] Thus, the hair entangled on the roller brush assembly 200 can be dealt with in time to ensure that the cleaning device can maintain a good operating state, improving the cleaning efficiency of the cleaning device, and preventing the roller brush assembly 200 from being worn by hair entanglement. Thus, the service life of the cleaning device can be extended.

[0060] In reference to Figures 1 to 5, in some embodiments, the floor brush structure further comprises a handle assembly 400 detachably connecting the cutting assembly 300 to the floor brush body 100.

[0061] It can be understood that by providing the handle assembly 400, the cutting assembly 300 can be detachably connected to the floor brush body 100, the disassembly and maintenance of the cutting assembly 300 and the roller brush assembly 200 can be made more convenient and quicker, the flexibility and versatility of use are better, and storage and transportation is facilitated.

[0062] Specifically, when a user assembles or disassembles the cutting assembly 300, the user can hold the handle assembly 400 to operate. By realizing the disassembly or assembly of the cutting assembly 300 by the detachable connection between the handle assembly 400 and the floor brush body 100, it is safer and more reliable.

[0063] In addition, in reference to Figures 1 to 4, and 6, the floor brush structure provided in the embodiment of the present application further comprises a connecting assembly 500 connecting the cutting assembly 300 to the handle assembly 400.

[0064] It can be understood that by providing the connecting assembly 500 between the cutting assembly 300 and the handle assembly 400 to respectively connect the cutting assembly 300 and the handle assembly 400, direct connection between the cutting assembly 300 and the handle assembly 400 is avoided, making the connection between the two more stable and reliable, and the use operation more flexible, which facilitates subsequent maintenance and replacement of either the handle assembly 400 or the cutting assembly 300 without affecting the other, thereby reducing the maintenance cost of the floor brush structure.

[0065] In addition, in reference to Figures 1 to 4 and 7, the floor brush structure provided by the embodiment of the present application further comprises a rotating assembly 600 that coaxially rotatably connects the cutting assembly 300 to the roller brush assembly 200.

[0066] It is easy to understand that with the cutting assembly 300 rotatably connected to the roller brush assembly 200, hair can be cut by the relative rotation between the cutting assembly 300 and the roller brush assembly 200 when it is entangled on the roller brush assembly 200, thereby improving hair cutting efficiency.

[0067] In addition, in this way, the roller brush assembly 200 can be mounted on the floor brush body 100 in sequence through the rotating assembly 600, the cutting assembly 300, the connecting assembly 500 and the handle assembly 400. The roller brush assembly 200 rotatably cooperates with the cutting assembly 300 only through the rotating assembly 600. Thus, not only is stable rotation of the roller brush assembly 200 ensured, but also, by reasonably controlling the rotational cooperation relationship of the roller brush assembly 200, the area where hair entanglement may occur is controlled to be between the cutting assembly 300 and the roller brush assembly 200, so that the function of the cutting assembly 300 can be fully exerted as much as possible, thereby improving its hair cutting efficiency.

[0068] In reference to Figures 2 and 4, the floor brush body 100 of the floor brush structure provided by the embodiment of the present application comprises a housing 110 and a driving member 120. The housing 110 has a mounting chamber adapted to the roller brush assembly 200. The driving member 120 is located in the mounting chamber. An end of the mounting chamber away from the driving member 120 has an opening, through which the roller brush assembly 200 is inserted into the mounting chamber and connected to the driving member 120. The driving member 120 drives the roller brush assembly 200 to rotate around its axis.

[0069] It should be noted that in actual use, in order to prevent dust from flying and protect the roller brush assembly 200 and the driving member 120, a cover (not shown) is further provided at the position corresponding to the roller brush assembly 200 outside the housing 110. The cover provides protection for the housing 110 and the side of the roller brush assembly 200 away from the floor. The housing 110 can be used to provide safety protection for the roller brush assembly 200 and the driving member 120, ensuring that the roller brush assembly 200 and the driving member 120 can operate normally and extending the service life of the cleaning device.

[0070] Specifically, a mounting chamber with an opening at an end is formed in the housing 110. The shape of the mounting chamber is adapted to the outer shape of the roller brush assembly 200. The driving member 120 is arranged at an end of the mounting chamber away from the opening. The roller brush assembly 200 is inserted into the mounting chamber along its own axial direction through the opening, and is connected to the driving member 120 in a transmission manner, to ensure that the cleaning device can perform cleaning work efficiently and easily, wherein the driving member 120 can be an electric motor or another component that can drive the roller brush assembly 200 to rotate around its own axis. The handle assembly 400, the cutting assembly 300, the connecting assembly 500 and the rotating assembly 600 are all assembled with the roller brush assembly 200 from an end of the mounting chamber facing the opening. Thus, the end of the roller brush assembly 200 connected to the driving member 120 is a driving end, and the end of the roller brush assembly 200 connected to the cutting assembly 300 is a driven end.

[0071] In addition, since the driving member 120 itself has a certain volume, in order to make the overall structure of the floor brush structure compact and prevent hair from being entangled between the driving member 120 and the roller brush assembly 200, an avoiding groove adapted to the driving member 120 can be provided at the end of the roller brush assembly 200 facing the driving member 120, and the driving member 120 can be inserted into the avoiding groove, so that an output end of the driving member 120 is connected to the bottom of the avoiding groove.

[0072] In some embodiments, in reference to Figures 2, 3, 4, 6 and 8, the connecting assembly 500 comprises a first connecting shaft 510, the handle assembly 400 comprises a handle body 410, and the cutting assembly 300 comprises a fixing frame 310. The first connecting shaft 510 is inserted into the handle body 410 and the fixing frame 310.

[0073] The handle body 410 extends along a side of the housing 110. The fixing frame 310 of the cutting assembly 300 is configured as a quasi-circular shape adapted to the mounting groove 312 of the roller brush assembly 200, and an avoiding opening 314 is provided at a side of the fixing frame 310. During specific connection, an end of the handle body 410 can be connected to the first connecting shaft 510 via the avoiding opening 314, and the first connecting shaft 510 can be further connected to the fixing frame 310.

[0074] Thus, the handle body 410 and the fixing frame are connected through the first connecting shaft 510, so that the connection between the handle body 410 and the fixing frame 310 is stable and reliable.

[0075] In addition, thanks to the first connecting shaft 510's own structure, the handle body 410 and the fixing frame 310 form a relative swing axis. When necessary, the handle body 410 and the fixing frame 310 can cooperate in a swingable manner relative to the first connecting shaft 510, making the connection between the handle body 410 and the fixing frame 310 more flexible and subsequent assembly and disassembly of the handle assembly 400 simple and quick.

[0076] Further, in reference to Figures 2, 3, 4, 6 and 8, the handle body 410 is provided with a first connecting hole 411, the fixing frame 310 is provided with a second connecting hole 311, and the first connecting shaft 510 is inserted into the first connecting hole 411 and the second connecting hole 311, so that the assembly and disassembly of the first connecting shaft 510 is more convenient and quicker.

[0077] It should be noted that, in this embodiment, a boss adapted to the avoiding opening 314 is provided on the handle body 410, the first connecting hole 411 is provided in the boss, and two second connecting holes 311 are coaxially provided in two end sides of the fixing frame 310 corresponding to the avoiding opening 314 respectively. When the first connecting shaft 510 is inserted, the first connecting shaft 510 sequentially passes through one of the second connecting holes 311, the first connecting hole 411 and the other second connecting hole 311, so as to connect the fixing frame 310 to the handle body 410.

[0078] In other embodiments, the forms and numbers of the first connecting hole 411 and the second connecting hole 311 can also be flexibly adjusted to ensure that the first connecting shaft 510 can pass through them coaxially in sequence. They are not limited by the present application.

[0079] In addition, an edge is provided at an end of the first connecting shaft 510 for cooperating with a corresponding connecting hole in an anti-rotation manner. The edge extends in the extension direction of the first connecting shaft 510. Thus, when the first connecting shaft 510 is inserted to the fixing frame 310, the first connecting shaft 510 is prevented from rotating relative to the fixing frame 310, and only its relative angle with the handle assembly 400 can change to a certain extent. In other embodiments, the edge can also be provided to the first connecting hole 411 to exchange the relative rotation relationship between the first connecting shaft 510, and the fixing frame 310 and the handle body 410. No limitation is made by the present application.

[0080] Further, in reference to Figures 2, 3, 4 and 6, the connecting assembly 500 further comprises a reset member 520 sleeved on the first connecting shaft 510 and respectively abutting against the handle body 410 and the fixing frame 310.

[0081] It can be understood that by sleeving on the first connecting shaft 510 the reset member 520 abutting against the handle body 410 and the fixing frame 310, the relative position between the handle body 410 and the fixing frame 310 can be maintained by the reset member 520 when there is no external force between the handle body 410 and the fixing frame 310, thereby ensuring that the connection between the handle assembly 400 and the cutting assembly 300 is more stable and reliable and making it more convenient to use.

[0082] In specific implementation, the reset member 520 is a torsion spring sleeved on the first connecting shaft 510. For this purpose, the boss on the handle body 410 can be arranged as two small bosses provided coaxially with the first connecting holes 411, and a mounting position of the reset member 520 is reserved between the two bosses, so that two ends of the reset member 520 (namely the torsion spring) respectively abut against the fixing frame 310 and the handle body 410.

[0083] Thus, when the fixing frame 310 and the handle body 410 swing relative to each other, the torsion spring is twisted and elastically deformed, and when an external force driving the fixing frame 310 and the handle body 410 to swing is released, the fixing frame 310 and the handle body 410 are driven to return to a preset angle position by the restoration of deformation of the torsion spring.

[0084] In addition, in some embodiments, the handle assembly 400 further comprises a snap-fit member 412 located on the handle body 410 and configured to snap fit or disengage from snap-fit with the floor brush body 100.

[0085] It should be noted that a snap slot for snap-fit cooperating with the snap-fit member 412 is provided in the floor brush body 100, and a pressing member 420 is provided. By applying an external force to the pressing member 420, the pressing member 420 can drive the snap-fit member 412 in the snap slot to disengage from snap-fit with the snap slot, so that a user can disassemble the handle assembly 400 and the cutting assembly 300.

[0086] Between the pressing member 420 and the snap-fit member 412, there is also provided a transmission member (not shown) correspondingly connected to the pressing member 420 and used to transmit an action of the pressing member 420 to the snap-fit member 412 and drive the snap-fit member 412 to disengage from snap-fit with the snap slot. The present application does not limit the specific structural arrangement of the pressing member 420 and the transmission member.

[0087] In this way, by snap-fit or disengagement from snap-fit between the snap-fit member 412 and the floor brush body 100, the handle assembly 400, the cutting assembly 300 and the roller brush assembly 200 can be detachably connected to the floor brush body 100, so that the assembly and disassembly of the floor brush structure is more convenient and efficient.

[0088] In some embodiments, in reference to Figures 2, 3, 4 and 7, the rotating assembly 600 comprises a rotary bearing 610 and a second connecting shaft 620. The rotary bearing 610 has an outer ring and an inner ring that rotatably cooperate with each other. The outer ring is fixedly connected to the cutting assembly 300. An end of the second connecting shaft 620 is fixedly inserted in the inner ring, and the other end of the second connecting shaft 620 is coaxially inserted to the roller brush assembly 200.

[0089] Specifically, with the outer ring of the rotary bearing 610 fixedly connected to the fixed frame 310 of the cutting assembly 300, relative rotation between the outer ring and the fixed frame 310 can be prevented. Similarly, with one end of the second connecting shaft fixedly inserted to the inner ring, and the other end coaxially inserted to the roller brush assembly 200, relative rotation between the second connecting shaft and any of the inner ring and the roller brush assembly 200 can be prevented, so that the rotatable cooperation between the cutting assembly 300 and the roller brush assembly 200 is realized only by the rotary bearing 610, which makes the rotation of the roller brush assembly 200 smooth and stable, with little noise and a long service life.

[0090] The outer ring can be made to transitionally cooperate with an annular groove at the center of the fixing frame 310, the second connecting shaft 620 can be made to transitionally cooperate with the inner ring, and an edge can also be provided on the second connecting shaft 620 in its extension direction, so that the second connecting shaft 620 is inserted to the accommodating groove 221 of the roller brush assembly 200 to ensure that neither end of the second connecting shaft 620 rotates relative to the corresponding connected component.

[0091] Further, still in reference to Figures 2, 3, 4, 5 and 7, the rotating assembly 600 further comprises a retaining ring member 630 located in the cutting assembly 300 and snap fitting with the outer ring.

[0092] It can be understood that the retaining ring is a C-shaped structure, so that the radial size of the retaining ring is variable. Thus, a retaining ring groove 315 can be provided in an annual groove at an inner side of the fixing frame 310. The retaining ring groove 315 is adapted in size to the retaining ring. When connecting the rotary bearing 610 to the fixing member, the retaining ring can be pre-mounted into the retaining ring groove 315, and when the rotary bearing 610 is subsequently mounted, the rotary bearing 610 is made to snap fit with the retaining ring to expand it such that the retaining ring cooperates with the retaining ring groove 315 in a stopping manner, so as to improve the reliability of the connection between the rotary bearing 610 and the fixing frame 310, and detachably connect the cutting assembly 300 to the rotary bearing 610, which facilitates subsequent assembly, disassembly and maintenance of the rotating assembly 600 and makes it more convenient and flexible to use.

[0093] In addition, in some embodiments, in reference to Figures 2, 3, 4 and 8, the cutting assembly 300 further comprises at least one blade 320. The fixing frame 310 has a mounting groove 312, the opening of which faces the inner side wall. The blade 320 is located in the mounting groove 312 with its cutting edge facing the opening of the mounting groove.

[0094] An annular mounting groove 312 adapted to the fixing frame 310 is provided in the outer peripheral side of the fixing frame 310. The blade 320 is mounted in the mounting groove 312 with its three sides other than the cutting edge are all correspondingly connected to the mounting groove 312, so that the mounting of the blade 320 is stable and reliable.

[0095] By providing the blade 320 in the opening facing the inner side wall of the accommodating groove 221 and orienting the cutting edge of the blade 320 towards the opening, when hair is entangled into the gap 222, it can first come into contact with the cutting edge, which cuts the hair when it becomes further entangled. With the blade 320 located in the mounting groove 312, safety protection performance of the cutting assembly 300 can be improved, and a user can be prevented from being cut.

[0096] Further, in reference to Figure 8, at least two blades 320 are provided, and the blades 320 are arranged in the mounting groove 312 in a spaced apart manner.

[0097] In this way, providing a plurality of blades 320 in a spaced apart manner can improve hair cutting efficiency, and help cut hair into short segments, which further reduces the possibility of hair entanglement.

[0098] In this embodiment, three blades 320 are provided in the mounting groove 312 in a spaced apart manner. Each blade 320 extends in the axial direction of the fixing frame 310 with the orientation of its cutting edge parallel to an axial section of the fixing frame 310 at that location. In other embodiments, more than two or four cutting edges can be provided, and the mounting directions and angles of the cutting edges can all be adaptively adjusted, which are not limited by the present application.

[0099] In addition, in reference to Figures 3 and 8, the cutting edge is lower than the opening of the mounting groove.

[0100] It can be understood that with the cutting edge lower than the opening of the mounting groove 312, the protective performance of the cutting assembly 300 can be strengthened, so that the cutting edge can only act on hair or other objects entering the mounting groove 312, preventing accidental injury to a user when the user assembles, disassembles or cleans the cutting assembly 300.

[0101] Moreover, with the cutting edge lower than the opening of the mounting groove, a space for hair winding can be formed in the mounting groove 312. The side wall of the mounting groove 312 is used to block hair, so as to prevent the hair from further entering the accommodating groove 221, so that the hair is wound around the mounting groove 312 and cut by the blade 320, thereby improving the cutting efficiency of the cutting assembly 300.

[0102] In addition, in specific implementation, in reference to Figure 3, the fixing frame 310 is at least partially exposed outside the accommodating groove 221. The part of the fixing frame 310 exposed outside the accommodating groove 221 forms a guide opening 313 of the gap 222 with the accommodating groove 221.

[0103] Since the fixing frame 310 is relatively located on the inner side of the accommodating groove 221 and is exposed outside the accommodating groove 221 to form the guide opening 313, the guide opening 313 can be used to guide the movement of hair to guide the hair to enter the gap 222 from the guide opening 313 and be cut by the cutting assembly 300, thereby improving the cutting efficiency of the cutting assembly 300 and thus reducing the possibility of hair entanglement on the roller brush assembly 200.

[0104] It should be noted that while the fixing frame 310 is exposed outside the accommodating groove 221, it is necessary to ensure that the mounting groove 312 in the fixing frame 310 is always located within the accommodating groove 221 to prevent the blade 320 from partially extending out of the accommodating groove 221 to cause safety hazards.

[0105] Specifically, the size of the fixing frame 310 on the side away from the accommodating groove 221 can be increased so that the fixing frame 310 partially extends out and forms the guide opening 313.

[0106] In addition, it should be noted that the roller brush assembly 200 comprises a drum 210 and an end cover 220 covering an end of the drum 210. The accommodating groove 221 is located in the end cover 220.

[0107] By arranging the drum 210 and the end cover 220 to be engaged by insertion to form a complete roller brush assembly 200, and arranging the accommodating groove 221 in the end cover 220, the structure of the roller brush assembly 200 can be made simpler and more compact, which facilitates subsequent maintenance and cleaning.

[0108] Thus, an additional disassembly form of the floor brush structure can be added, that is, one can not only disassemble the floor brush structure into a complete assembly of the cutting assembly 300, the handle assembly 400, the connecting assembly 500 and the rotating assembly 600, but also further disassemble the assembly into an assembly with the end cover 220, and an independent drum 210, so as to use the end cover 220 to provide physical protection for the blade 320 of the cutting assembly 300, ensuring user safety.

[0109] The present application further provides embodiments of a cleaning device comprising a device body and any above-described floor brush structure. The floor brush structure is connected to the device body.

[0110] The floor brush structure has been described in detail in the above embodiments and will not be repeated here.
