Technical Field

[0001] This invention relates to the field of mechanical technology, and more particularly to a floor brush and a movable device. Background Technology

[0002] With the development of technology, various portable cleaning devices have entered people's lives to make them more convenient. Examples include household cleaning machines, vacuum cleaners, and robotic vacuum cleaners. Taking cleaning machines as an example, people can use them to perform vacuuming and mopping tasks themselves. After using a cleaning machine, to ensure that the parts in contact with water inside the brush assembly are effectively dried and to prevent bacterial growth, it is usually necessary to disassemble the roller brush and brush cover from the main unit of the cleaning machine for cleaning and maintenance.

[0003] However, the connection between the roller brush and roller brush cover and the main unit of the cleaning machine currently in use is very complicated, which makes the disassembly and assembly steps cumbersome and greatly increases the disassembly time.

[0053] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0054] In the process of implementing the embodiments of the present invention, the inventors found that it is currently very difficult for users to disassemble the roller brush and roller brush cover, resulting in a poor user experience when using the cleaning machine.

[0055] The reason for this is that the connection between the roller brush and the roller brush cover and the main unit of the cleaning machine is very complicated, which makes the disassembly and assembly steps cumbersome and greatly increases the disassembly time. Sometimes, the complexity is so great that users cannot remove the roller brush and roller brush cover from the main unit, which reduces the user experience.

[0056] To address the aforementioned problems, embodiments of the present invention provide a floor brush and a movable device that solves these problems, thereby avoiding the aforementioned difficulties in disassembly and assembly.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0058] Figure 11 This is a three-dimensional structural diagram of another floor brush provided in an embodiment of the present invention, showing the floor brush body and the roller brush assembly separated. Figure 12 This is an exploded structural diagram of another roller brush body provided in an embodiment of the present invention.

[0059] See Figure 4 In one embodiment of the present invention, a movable device is provided, including a device body 30 and a floor brush. The floor brush is connected to the device body 30 via a floor brush body 10. See [link to relevant documentation]. Figures 11 to 12 As shown. The floor brush includes a floor brush body 10 and a roller brush body 23. A first connecting portion 12 is provided at one end of the floor brush body 10. A second connecting portion 22, which cooperates with the first connecting portion 12, is provided at one end of the roller brush body 23 along the axial direction. The first connecting portion 12 and the second connecting portion 22 cooperate to mount the roller brush body 23 onto the floor brush body 10. The second connecting portion 22 is detachably connected to the first connecting portion 12.

[0060] The second connecting part 22 is provided with a first hand-holding structure 40 for hand gripping. The first hand-holding structure 40 is used to grip the brush body 23 so that the second connecting part 22 of the brush body 23 can be disengaged from the first connecting part 12 of the brush body 10.

[0061] The technical solution provided in this embodiment of the invention is that both ends of the roller brush body 23 are detachably connected to the floor brush body 10. A first hand-held structure 40 is provided on the roller brush body 23 for the user to hold, which makes it convenient for the user to apply force to the roller brush body 23 and to detach and install the roller brush body 23 from the floor brush body 10, thereby reducing the user's operating difficulty and maintenance time.

[0062] In some feasible embodiments, the brush body 10 has a first driving part 11 and a first connecting part 12 at opposite ends. The roller brush body 23 has a second driving part 21 that cooperates with the first driving part 11 and a second connecting part 22 that cooperates with the first connecting part 12 at opposite ends along the axial direction. The second driving part 21 is detachably connected to the first driving part 11, and the second connecting part 22 is detachably connected to the first driving part 11.

[0063] To facilitate user assembly and disassembly, in this embodiment of the invention, the first driving part 11 and the second driving part 21, as well as the first connecting part 12 and the second connecting part 22, can be snap-fitted together. This facilitates user assembly and disassembly. For example, the first driving part 11 may include a motor with a drive shaft 111, and the second driving part 21 can be inserted into the drive shaft 111 along its axial direction. The first connecting part 12 can be a snap-fit ​​groove, and the second connecting part 22 can be an elastic snap-fit ​​buckle. The elastic snap-fit ​​buckle and the snap-fit ​​groove are engaged to connect the second connecting part 22 to the brush body 10. The user can firmly hold the second connecting part 22 through the first handheld structure 40, facilitating the application of force to the second connecting part 22 and the connection and separation of the elastic snap-fit ​​buckle and the snap-fit ​​groove.

[0064] In this embodiment of the invention, the floor brush can be applied to a mobile device, which includes, but is not limited to, cleaning machines, robotic vacuum cleaners, and other similar devices. One implementation of the mobile device is as follows: [See...] Figure 4 The movable device includes a main body 30 and a floor brush mounted on the main body 30. The floor brush can be connected to the main body 30 via a floor brush body 10. To facilitate the movement of the floor brush, the floor brush body 10 is also equipped with multiple travel wheels. The main body 30 is equipped with a water supply system that sprays water onto the floor during operation, thus working in conjunction with the floor brush to clean the floor. Simultaneously, the main body 30 is also equipped with a suction system that creates negative pressure during operation, allowing dirt and wastewater to be sucked from the floor through suction channels on the floor brush body 10. Of course, the main body 30 may also include control systems and other functional units, which will not be detailed here.

[0065] In some possible embodiments of the present invention, see also... Figure 11 and Figure 12 One implementation of the first hand-held structure 40 is that it is a groove structure. The user can insert his / her fingers into the groove structure, so that the fingers are fitted onto the second connecting part 22, thereby increasing the contact area between the fingers and the second connecting part 22 and facilitating the application of force by the hand.

[0066] Depending on the specific requirements, there are various ways to configure the groove structure. One possible approach is to refer to [link to relevant documentation]. Figure 11 and Figure 12 The groove structure is provided on the circumferential side of the second connecting part 22. The user's finger can be inserted into the groove structure in the radial direction of the second connecting part 22. When a force is applied in the circumferential direction of the second connecting part 22, the second connecting part 22 can rotate circumferentially, thereby driving the roller brush body 23 to rotate. When a force is applied in the axial direction of the roller brush body 23, the second connecting part 22 can move axially, thereby driving the roller brush body 23 to translate.

[0067] Another possible implementation of the groove structure is that the groove structure is located on the end face of the second connecting portion facing away from the brush body. The user's finger can be inserted into the groove structure along the axial direction of the brush body 23. When a force is applied along the circumferential direction of the second connecting portion 22, the brush body 23 can be rotated. Alternatively, when a finger is inserted into the groove structure, and other fingers grasp the second connecting portion 22, and a force is applied along the axial direction of the brush body 23, the brush body 23 can be translated.

[0068] Furthermore, to facilitate finger movement in and out of the groove structure, another possible implementation of the groove structure is as follows: [See...] Figure 11 and Figure 12 The groove structure extends through the circumferential side of the second connecting part 22 and both end faces of the second connecting part 22 along the axial direction of the brush body 23. This through-groove design makes the groove structure more suitable for different users' fingers; thinner fingers can fully insert into the groove structure, while thicker fingers can at least partially insert. Extending through both ends of the second connecting part 22 along its axial direction, the user's fingers can insert more into the groove structure, making it easier and less difficult for the user to apply force.

[0069] Further, see also Figure 11 Another configuration of the first hand-held structure 40 is that the second connecting part 22 of the roller brush body 23 is located on the connecting plate 70 at one end of the roller brush body 23, and the first hand-held structure 40 is a groove on the connecting plate 70 for hand gripping. The user can insert their fingers into the groove to fit their fingers into the second connecting part 22, thereby increasing the contact area between the fingers and the second connecting part 22 and facilitating the application of force by the hand.

[0070] One possible implementation of the connecting plate 70 is that it includes an end face facing the brush body 10 and an end face away from the roller brush body 23, with a groove penetrating both the end face facing the brush body 10 and the end face away from the roller brush body 23. This through-hole design makes the groove more suitable for different users' fingers; thinner fingers can fully insert into the groove, while thicker fingers can at least partially insert. Penetrating both axial ends of the second connecting portion 22, the user's fingers can insert more into the groove, making it easier for the user to apply force and reducing the difficulty of applying force.

[0071] Furthermore, see Figure 11 and Figure 16 The connecting plate 70 includes a connecting plate portion 71 located above the groove. When the first connecting portion 12 and the second connecting portion 22 are engaged, the connecting plate portion 71 forms part of the outer contour of the floor brush body 10. When the first connecting portion 12 and the second connecting portion 22 are engaged, the connecting plate portion 71 smoothly transitions with the floor brush body 10, avoiding the occupation of extra space and making the floor brush look more aesthetically pleasing.

[0072] Furthermore, one method of disassembling the roller brush body 23 is to disassemble it by first rotating it around the axial line and then translating it to one side. See also... Figure 11 The first hand-held structure 40 is for the user to hold. A rotational force is first applied to the first hand-held structure 40 in a direction away from the main body of the floor brush 10, i.e., along... Figure 11 A force is applied in the direction indicated by the dashed arc arrow to rotate the brush body 23 around the axial line via the first handheld structure 40, causing the first connecting part 12 to disengage from the second connecting part 22, thus separating the second connecting part 22 from the first connecting part 12. Then, a pulling force is applied to the first handheld structure 40 along the axial direction of the brush body 23. Figure 11 Apply force in the direction indicated by the dashed straight arrow to move the roller brush body 23 to one side via the first hand-held structure 40, thereby completing the disassembly of the roller brush body 23.

[0073] The installation process is the reverse of the disassembly process; that is, a pushing force is first applied to the first hand-held structure 40 along the axial direction of the roller brush body 23. Figure 11 Applying force in the direction indicated by the solid straight arrow, the first handheld structure 40 drives the roller brush 23 to move to one side, completing the connection between the first drive unit 11 and the second drive unit 21. Then along... Figure 11 Applying force in the direction indicated by the solid arc arrow in the middle, the first hand-held structure 40 drives the roller brush body 23 to rotate around the axial line, so that the second connecting part 22 and the first connecting part 12 are connected to each other, thus completing the connection between the roller brush body 23 and the floor brush body 10.

[0074] Furthermore, in the embodiments of the present invention, the floor brush can be implemented in various ways, which will be described separately below through specific embodiments. It should be noted that the relevant technical features and their connection methods in each embodiment can be referenced and learned from each other without conflict. The structures shown in the accompanying drawings are only exemplary and cannot be used as an improper limitation of the embodiments of the present invention.

[0075] One feasible method for using floor brushes is to combine... Figures 1 to 3 See Figure 5 and Figure 6The roller brush assembly 20 includes a roller brush body 23 and a roller brush cover 24. A second driving portion 21 and an elastic connecting assembly 25 are respectively provided at opposite ends of the roller brush body 23 along the axial direction. A second connecting portion 22 is provided on the roller brush cover 24. Along the length direction (in this embodiment, the length direction of the roller brush cover 24 is the axial direction of the roller brush body 23), a first connecting wall 241 and a second connecting wall 242 are respectively provided at opposite ends of the roller brush cover 24. The first connecting wall 241 and the second connecting wall 242 form an accommodating space. A connecting hole 2411 is provided on the first connecting wall 241, and an annular groove 2421 is provided on the second connecting wall 242.

[0076] The roller brush body 23 is rotatably connected within the accommodating space, wherein the second drive unit 21 abuts against the first connecting wall 241 and is connected to the first drive unit 11 through the connecting hole 2411. The elastic connecting assembly 25 abuts against the second connecting wall 242 and is partially engaged within the annular groove 2421.

[0077] The roller brush cover 24 is adapted to the outer surface of the roller brush body 23 and covers the roller brush body 23. The roller brush cover 24 can cover the upper part of the roller brush body 23, and the roller brush cover 24 and the cleaning surface form a space for the roller brush body 23 to roll. The roller brush cover 24 can prevent the roller brush body 23 from throwing dirt, sewage and other substances to the outer periphery.

[0078] During installation, please refer to Figure 5 First, the roller brush body 23 can be connected to the receiving space on the roller brush cover 24. Specifically, first, the second drive part 21 on the roller brush body 23 is abutted against the first connecting wall 241; then, the elastic connecting component 25 is pressed, or the elastic connecting component 25 is squeezed through the second connecting wall 242, to create a channel that allows the roller brush body 23 to enter the receiving space; then, along... Figure 5 As indicated by the dashed arrow, the roller brush body 23 is placed into the receiving space. When the elastic connecting component 25 moves onto the annular groove 2421, the force applied to the elastic connecting component 25 disappears, and part of the elastic connecting component 25 springs in and engages within the annular groove 2421. The state in which the roller brush body 23 and the roller brush cover 24 are connected can be seen in [reference needed]. Figure 6 .

[0079] At this point, the roller brush body 23 and the roller brush cover 24 can be considered as a single unit, thus forming the roller brush assembly 20. The process of installing the roller brush assembly 20 onto the floor brush body 10 is as follows, see [link to documentation]. Figure 3 First along Figure 3 The direction of the dashed arrow indicates the connection between the second drive unit 21 and the first drive unit 11. For example, the first drive unit 11 may include a drive shaft 111, and the second drive unit 21 may be inserted into the drive shaft 111 along its axial direction. See [link to image / description] for the state after the second drive unit 21 and the first drive unit 11 are connected. Figure 2Then, along Figure 2 As indicated by the dashed arrow, rotate the roller brush assembly 20 so that the second connecting part 22 engages with the first connecting part 12. For example, the first connecting part 12 can be a snap-fit ​​groove, and the second connecting part 22 can be an elastic snap-fit ​​buckle. The elastic snap-fit ​​buckle engages with the snap-fit ​​groove to connect the second connecting part 22 to the floor brush body 10, thus completing the connection between the roller brush assembly 20 and the floor brush body 10.

[0080] The process of removing the roller brush assembly 20 from the floor brush body 10 is the reverse of the installation process described above. See [link to relevant documentation]. Figure 2 Along Figure 2 Rotate the brush assembly 20 in the direction indicated by the solid arrow to disengage the second connecting part 22 from the first connecting part 12. Then, see... Figure 3 , and then along Figure 3 The direction of the solid arrow in the middle is used to translate the second drive unit 21, so that the second drive unit 21 is disengaged from the first drive unit 11, thereby completing the disassembly of the roller brush assembly 20 and the floor brush body 10.

[0081] The process of removing the roller brush body 23 from the roller brush cover 24 is as follows: See Figure 6 ,along Figure 6 In the direction indicated by the solid arrow, press the elastic connecting component 25 so that it disengages from the annular groove 2421, creating a channel for the brush body 23 to exit from the receiving space; then, see... Figure 5 along Figure 5 As indicated by the solid arrow, the end of the roller brush 23 is moved out of the accommodating space. At this time, the second drive part 21 on the roller brush 23 is disengaged from the first connecting wall 241, and the roller brush 23 can be moved out horizontally, so that the roller brush 23 can be cleaned and maintained.

[0082] To further facilitate the installation of the roller brush body 23, in this embodiment of the invention, see below. Figure 6 The axial lines of the roller brush body 23, the first connecting wall 241, the second connecting wall 242, and the first drive unit 11 are all on the same straight line. The roller brush body 23 can be positioned by the annular groove 2421 and the first connecting wall 241, so that the roller brush body 23, the roller brush cover 24, and the first drive unit 11 are on the same axial line. This makes it convenient to disassemble the roller brush assembly 20 by first rotating it around the axial line and then moving it to one side. This facilitates the rotation and disassembly of the roller brush assembly 20 relative to the brush body 10, while also ensuring the rolling operation of the roller brush body 23 in the roller brush assembly 20.

[0083] In an embodiment of the present invention, a roller brush body 23 can be implemented by combining... Figure 5 and Figure 6 See Figures 7 to 9The roller brush body 23 includes a cylindrical connecting frame 231, a driving bristle pressing block 232, a driven bristle pressing block 233, and an elastic connecting assembly 25. The outer periphery of the cylindrical connecting frame 231 is provided with roller brush bristles 234. The roller brush bristles 234 can be glued to the outer periphery of the cylindrical connecting frame 231, or can be fixed by winding around it.

[0084] Along the axial direction of the cylindrical connecting frame 231, the driving pressing block 232 and the driven pressing block 233 are respectively fixed inside the opposite ends of the cylindrical connecting frame 231, and the driving pressing block 232 abuts against the first connecting wall 241. In one connection method, both the driving pressing block 232 and the driven pressing block 233 are elastic and have a ring structure. The diameters of the driving pressing block 232 and the driven pressing block 233 are slightly larger than the diameter of the cylindrical connecting frame 231, so that the driving pressing block 232 and the driven pressing block 233 can be directly inserted into the cylindrical connecting frame 231 to form an interference fit connection.

[0085] Furthermore, in embodiments of the present invention, see... Figure 7 and Figure 8 One possible implementation of the cylindrical connecting frame 231 is that it includes an outer ring wall 2312 and an inner ring wall 2313 located inside the outer ring wall 2312, with the outer ring wall 2312 and the inner ring wall 2313 connected by multiple connecting ribs. The two opposite ends of the inner ring wall 2313 along the axial direction are located within the outer ring wall 2312, and respectively form cavities with the inner walls of the outer ring wall 2312 for mounting the driving pressing block 232 and the driven pressing block 233. The driving pressing block 232 and the driven pressing block 233 can be inserted into the cavities at both ends, forming an interference fit connection. Simultaneously, to improve connection stability, the driving pressing block 232 and the driven pressing block 233 can partially extend into the inner ring wall 2313 and connect with it. In some other embodiments of the present invention, the cylindrical connecting frame 231 can also be implemented by a columnar structure. The columnar structure has axially extending mounting grooves at both ends, and the driving pressing block 232 and the driven pressing block 233 are connected through the mounting grooves.

[0086] One possible implementation of the elastic connection assembly 25 is that it includes a release operation part 251 and a driven shaft 252 disposed on the release operation part 251. A spring 253 is sleeved on the driven shaft 252, and the spring 253 is located between the release operation part 251 and the driven pressing block 233. The driven shaft 252 and the driven pressing block 233 are rotatably connected and can move along the axial direction of the driven shaft 252. The release operation part 251 and the driven shaft 252 can be integrally molded or separate structures. When the release operation part 251 and the driven shaft 252 are separate structures, the driven shaft 252 can be fixedly connected to the release operation part 251 by injection molding inserts. Under the action of external force, the release operation part 251 can retract into the cylindrical connecting frame 231, and the spring 253 deforms. When the external force disappears, under the elastic force of the spring 253, the release operation part 251 can extend out of the cylindrical connecting frame 231.

[0087] Combination Figure 5 and Figure 6 ,by Figure 8 Taking the Chinese position as an example, along Figure 6 As indicated by the solid arrow, a force is applied to the release operation part 251, causing it to move to the right and compress the spring 253. At this time, the driven shaft 252 also moves to the right, and the release operation part 251 disengages from the annular groove 2421, thus allowing the brush body 23 to be removed from the brush cover 24. After the external force is removed, under the elastic force of the spring 253, the release operation part 251 can extend from the cylindrical connecting bracket 231, and the driven shaft 252 moves to the left.

[0088] During installation, press the release operation part 251, or squeeze the release operation part 251 through the second connecting wall 242. The release operation part 251 can retract into the cylindrical connecting frame 231 and compress the spring 253, causing the driven shaft 252 to move to the right. The roller brush body 23 can be placed into the receiving space. When the release operation part 251 moves onto the annular groove 2421, the force applied to the release operation part 251 disappears. Under the restoring force of the spring 253, the release operation part 251 is partially springed into and locked into the annular groove 2421. When the first drive unit 11 drives the cylindrical connecting frame 231 to rotate, the drive bristle pressing block 232 and the driven bristle pressing block 233 rotate synchronously with the cylindrical connecting frame 231. At this time, the driven bristle pressing block 233 rotates relative to the driven shaft 252.

[0089] See also Figure 7 and Figure 8To avoid hard friction between the driven shaft 252 and the driven pressing block 233, in this embodiment of the invention, the driven pressing block 233 is provided with a transition groove 2331 at its center along the axial direction, and the bottom of the transition groove 2331 is provided with a transition hole. A bearing component 2332 is provided inside the transition groove 2331. The outer ring of the bearing component 2332 is fixedly connected to the inner wall of the transition groove 2331, and the inner ring of the bearing component 2332 communicates with the transition hole. The driven shaft 252 is sleeved inside the inner ring of the bearing component 2332, and is rotatably connected to the inner ring of the bearing component 2332 and can move along the axial direction of the driven shaft 252. When the driven pressing block 233 rotates relative to the driven shaft 252, the bearing 2332 ensures smoother rotation and prevents hard friction between the driven shaft 252 and the driven pressing block 233. This avoids wear on both, effectively extending their service life and further reducing subsequent maintenance costs and time. The bearing 2332 can be fixed to the inner wall of the adapter groove 2331 by injection molding or by bonding it to the inner wall of the adapter groove 2331.

[0090] Furthermore, to prevent the spring 253 from ejecting the driven shaft 252 from the bearing component 2332, a limiting structure 2521 is provided on the end of the driven shaft 252 away from the release operation part 251. The limiting structure 2521 can be a limiting screw or a limiting stop provided at the end of the driven shaft 252. Taking a limiting screw as an example, see [reference needed]. Figure 8 The limiting screw can be released from the side of the bearing 2332 away from the operating part 251 (i.e., Figure 8 The driven shaft 252 (on the right side) passes through the inner ring of the bearing 2332 and connects to the driven shaft 252. The nut of the limit screw is blocked on the right side by the inner ring of the bearing 2332. When the spring 253 drives the release operating part 251 to move to the left, the nut of the limit screw can limit the movement distance of the driven shaft 252 and prevent the driven shaft 252 from dislodging from the bearing 2332.

[0091] See also Figure 7 and Figure 8 To further protect the driven shaft 252 and the bearing component 2332, in this embodiment of the invention, a protective sleeve 26 is fixedly provided on the inner ring of the bearing component 2332, and the driven shaft 252 is sleeved inside the protective sleeve 26. The diameter of the protective sleeve 26 can be slightly larger than the diameter of the inner ring of the bearing component 2332, so that the protective sleeve 26 can be pressed onto the inner ring of the bearing component 2332, resulting in an interference fit connection between the protective sleeve 26 and the inner ring of the bearing component 2332. The driven shaft 252, sleeved inside the protective sleeve 26, connects to the bearing component 2332 through the protective sleeve 26, thereby reducing wear between the driven shaft 252 and the bearing component 2332 and achieving protection for both the driven shaft 252 and the bearing component 2332.

[0092] Furthermore, to prevent the brush bristles 234 from winding around the driven shaft 252 when the brush body 23 rotates, in this embodiment of the invention, see [reference needed]. Figure 12 An anti-tangling cap 27 is fitted onto the driven shaft 252. The anti-tangling cap 27 prevents the brush bristles 234 from entering the driven shaft 252, thus avoiding tangling of the brush bristles 234 onto the driven shaft 252. It should be noted that... Figure 12 The structure shown is another implementation of the roller brush body 23 provided by the embodiment of the present invention. In the absence of structural conflicts, the arrangement of each component can be referenced to each other, which should not be regarded as an improper limitation of the embodiment of the present invention.

[0093] See Figure 9 To ensure a more stable connection between the driving bristle pressing block 232 and the first connecting wall 241, in this embodiment of the invention, a first annular rib 2322 is provided around the outer periphery of the driving bristle pressing block 232. A second annular rib 2412 is provided around the outer periphery of the connecting hole 2411 on the first connecting wall 241, and the second annular rib 2412 is fitted inside the first annular rib 2322. The diameter of the second annular rib 2412 is smaller than the diameter of the first annular rib 2322. Through the fitted engagement between the first annular rib 2322 and the second annular rib 2412, the connection between the driving bristle pressing block 232 and the first connecting wall 241 is made more stable, effectively preventing the roller brush assembly 20 from detaching from the roller brush cover 24.

[0094] Further, see also Figures 2 to 3 To ensure a more secure connection between the roller brush cover 24 and the floor brush body 10, in this embodiment of the invention, the floor brush body 10 is provided with a first locking connection portion 13. The roller brush cover 24 is provided with a second locking connection portion 243 that cooperates with the first locking connection portion 13. The second locking connection portion 243 is connected to the first locking connection portion 13 and locks the relative position between the roller brush cover 24 and the floor brush body 10. The first locking connection portion 13 and the second locking connection portion 243 can be implemented in various ways. For example, one of the first locking connection portion 13 and the second locking connection portion 243 can be an elastic buckle, and the other can be a slot. Alternatively, one of the first locking connection portion 13 and the second locking connection portion 243 can be an elastic latch, and the other can be a locking hole. After the first locking connection portion 13 and the second locking connection portion 243 are connected, displacement of the roller brush cover 24 relative to the floor brush body 10 can be prevented, thereby ensuring the stability of the position of the roller brush assembly 20 relative to the floor brush body 10 and ensuring the stable operation of the roller brush assembly 20.

[0095] When disassembling the roller brush assembly 20 from the brush body 10, first separate the second locking connection 243 from the first locking connection 13, then rotate the roller brush assembly 20 to separate the second connection 22 from the first connection 12, thus completing the disassembly. During installation, after connecting the second connection 22 to the first connection 12, connect the second locking connection 243 to the first locking connection 13, thereby connecting the roller brush cover 24 to the brush body 10. In this configuration, when cleaning and maintenance of the roller brush body 23 is required, it is not necessary to remove the roller brush body 23 and the roller brush cover 24 together from the brush body 10; only the roller brush body 23 needs to be removed from the roller brush cover 24.

[0096] See Figure 5 and Figure 6 The roller brush cover 24 can be connected to the first locking connection part 13 on the floor brush body 10 via the second locking connection part 243, at which point the floor brush body 10 and the roller brush cover 24 can be considered as a whole. When it is necessary to remove the roller brush body 23, along... Figure 6 In the direction indicated by the solid arrow, a force is applied to the release operation part 251, causing the release operation part 251 to disengage from the annular groove 2421, thereby enabling the roller brush body 23 to be removed from the roller brush cover 24.

[0097] During installation, first connect the second drive unit 21 to the first drive unit 11. Then, press the release operation unit 251, or squeeze the release operation unit 251 through the second connecting wall 242. The release operation unit 251 retracts into the cylindrical connecting frame 231, so that the roller brush body 23 can be placed into the accommodating space. When the release operation unit 251 moves to the annular slot 2421, the force applied to the release operation unit 251 disappears. Under the restoring force of the spring 253, the release operation unit 251 is partially ejected and locked in the annular slot 2421.

[0098] It should be noted that when removing the brush cover 24 together with the brush body 23, please refer to... Figure 3 Since the roller brush assembly 20 can be moved horizontally, the first drive unit 11 can include either a longer drive shaft 111 or a shorter drive shaft 111. When the roller brush cover 24 is not removed, and only the roller brush body 23 is removed, an excessively long drive shaft 111 may obstruct the movement of the roller brush body 23 from the receiving space. Therefore, the length of the drive shaft 111 can be set to a shorter value so that the drive shaft 111 can meet the needs of driving the roller brush body 23, and can also not obstruct the roller brush body 23 when it is being removed. Alternatively, the first drive unit 11 can include an end face toothed disc structure, and the second drive unit 21 is a structure that works in conjunction with the end face toothed disc structure. The end face toothed disc structure does not require a long axial length, so the end face toothed disc structure will not obstruct the roller brush body 23.

[0099] Furthermore, for easy disassembly of the roller brush body 23, see [link to relevant documentation]. Figure 7 The release operation unit 251 is also equipped with a handle 28, which may be C-shaped, with both ends rotatably connected to the release operation unit 251. The release operation unit 251 has a storage space. When not in use, the handle 28 can be neatly stored in the storage space on the release operation unit 251 without taking up extra space. When in use, the handle 28 can be rotated out from the storage space, and the user can use the handle 28 to remove the roller brush body 23 from the roller brush cover 24.

[0100] In one embodiment of the present invention, the first driving unit 11 and the second driving unit 21 are implemented as follows: See Figure 3 The first driving unit 11 includes a driving shaft 111, and a first driving engagement portion is provided circumferentially on the outer wall of the driving shaft 111. See also Figure 9 The driving pressing block 232 has a through hole 2321 at its center. The second driving part 21 includes a first driving hole 2311 on the cylindrical connecting frame 231. The inner wall of the first driving hole 2311 has a second driving engagement part that cooperates with the first driving engagement part. The driving shaft 111 can pass through the connecting hole 2411 and the through hole 2321 in sequence and be fitted into the first driving hole 2311. The first driving engagement part and the second driving engagement part engage so that the driving shaft 111 can drive the cylindrical connecting member to rotate circumferentially along the driving shaft 111. Further, the first driving hole 2311 can be provided on the inner annular wall 2313 of the cylindrical connecting frame 231.

[0101] The first and second drive engagement parts can be implemented in various ways. For example, the first drive engagement part can be a plurality of protruding structures arranged circumferentially along the drive shaft 111, and the second drive engagement part can be a groove-shaped structure arranged on the inner wall of the first drive hole 2311. Of course, the protruding structures can also be arranged on the first drive hole 2311, and the groove-shaped structure can be arranged on the drive shaft 111. When the drive shaft 111 is fitted into the first drive hole 2311, the protruding structures and the groove-shaped structure engage. When the drive shaft 111 rotates, it can drive the cylindrical connector to rotate.

[0102] Another implementation of the first driving part 11 and the second driving part 21 is as follows: the second driving part 21 includes a second driving hole located at the center of the driving pressing block 232, and a third driving engaging part is provided on the inner wall of the second driving hole to cooperate with the first driving engaging part. The driving shaft 111 can pass through the connecting hole 2411 and be fitted into the second driving hole. The first driving engaging part and the third driving engaging part engage, so that the driving shaft 111 drives the cylindrical connecting member to rotate circumferentially along the driving shaft 111 through the driving pressing block 232. The third driving engaging part is a structure adapted to cooperate with the first driving engaging part. Depending on the shape of the first driving engaging part, the third driving engaging part can be a groove-shaped structure or a protruding structure.

[0103] It should be noted that the two implementation methods of the first driving part 11 and the second driving part 21 described above can be implemented individually or in combination. Simultaneously, the first driving engagement part can also be provided with protruding structures and grooved structures at intervals, and the second driving engagement part and the third driving engagement part can be provided with corresponding cooperating structures. In this embodiment of the invention, no specific limitations are made. Furthermore, the first driving part 11 and the second driving part 21 can also be implemented using an end-face gear disk structure.

[0104] Combination Figure 8 See Figure 10 In one embodiment of the present invention, the roller brush bristles 234 can be implemented such that the roller brush bristles 234 extend radially along the cylindrical connecting frame 231, and the length of the roller brush bristles 234 can be set according to different cleaning needs. For example, Figure 10 In this context, N represents the length of the roller brush bristles 234. N can be set according to the degree of dirtiness of the cleaning surface. When the cleaning surface is dirty and wet, a roller brush bristle 234 with a larger N value can be selected. When the cleaning surface is clean and dry, a roller brush bristle 234 with a smaller N value can be selected. Of course, the value of N can also be set according to different cleaning needs. In this embodiment of the invention, no specific limitation is made.

[0105] See Figure 8 and Figure 9 In this embodiment of the invention, after the roller brush body 23 is installed on the roller brush cover 24, there are very few components between the roller brush body 23 and the first connecting wall 241 and the second connecting wall 242, and all of them are set inside the cylindrical connecting frame 231. Therefore, the gap between the two ends of the roller brush body 23 and the first connecting wall 241 and the second connecting wall 242 is very small. The first connecting wall 241 and the second connecting wall 242 can be regarded as the edges of the floor brush body 10. In other words, the area traversed by the first connecting wall 241 and the second connecting wall 242 is the cleaning edge of the floor brush. Since the two ends of the roller brush body 23 can be very close to the first connecting wall 241 and the second connecting wall 242, the roller brush bristles 234 provided on the roller brush body 23 can clean corners and other dead corners. After cleaning the corner areas, the residue of dirt can be effectively avoided. To further increase the cleaning range of the roller brush body 23, in this embodiment of the invention, the first connecting wall 241 and the second connecting wall 242 can be configured to have a minimum thickness while satisfying the requirement of supporting the roller brush body 23, so that the roller brush bristles 234 can be closer to the cleaning edge.

[0106] Another way to increase the cleaning range of the roller brush 23 is, see [link to relevant documentation]. Figure 8The roller brush bristles 234 extend radially along the cylindrical connecting frame 231. In the cleaning state, the roller brush bristles 234 extend beyond the cylindrical connecting frame 231 and outwards towards the first connecting wall 241. If a longer roller brush bristle 234 is selected, and the thickness of the first connecting wall 241 is set to be very thin, the roller brush bristles 234, under the influence of the gravity of the roller brush body 23 in the cleaning state, can extend beyond the cylindrical connecting frame 231 and outwards towards the first connecting wall 241, thereby increasing the cleaning range of the roller brush body 23 and achieving effective cleaning of corner areas.

[0107] Furthermore, at least one end of the roller brush sliver 234 located away from the first drive unit 11 can extend beyond the cylindrical connecting frame 231 along the axial direction of the cylindrical connecting frame 231. A longer roller brush sliver 234 can be selected, extending radially along the cylindrical connecting frame 231. Simultaneously, the thickness of the first connecting wall 241 and the second connecting wall 242 is relatively thin. This allows the roller brush sliver 234, under the influence of the roller brush body 23's gravity during cleaning, to extend beyond the cylindrical connecting frame 231 and outwards towards the first connecting wall 241, thereby increasing the cleaning range of the roller brush body 23 and achieving effective cleaning of corner areas.

[0108] In this embodiment of the invention, in addition to the above-described implementation method, the floor brush can also be implemented in the following ways.

[0109] Another feasible method for using a floor brush is, see [link to relevant documentation] Figure 11 The floor brush includes a floor brush body 10 and a roller brush assembly 20. The floor brush body 10 has a first driving part 11 and a first connecting part 12 at opposite ends. The roller brush assembly 20 has a second driving part 21 that cooperates with the first driving part 11 and a second connecting part 22 that cooperates with the first connecting part 12 at opposite ends along the axial direction. The second driving part 21 is detachably connected to the first driving part 11, and the second connecting part 22 is detachably connected to the first driving part 11. The structure of the floor brush body 10 can be referred to the structure of the floor brush body 10 described above, and will not be repeated here. The only difference from the above embodiment is the different configuration of the roller brush assembly 20. The specific scheme is as follows:

[0110] In this embodiment of the invention, combined with Figure 11 See Figure 12 The roller brush assembly 20 includes a roller brush body 23, which includes a cylindrical connecting frame 231, a driving bristle pressing block 232, a driven bristle pressing block 233, and a second connecting part 22. Roller brush bristles 234 are provided on the outer periphery of the cylindrical connecting frame 231. The roller brush bristles 234 can be glued to the outer periphery of the cylindrical connecting frame 231, or can be fixed by winding around the outer periphery of the cylindrical connecting frame 231.

[0111] Along the axial direction of the cylindrical connecting frame 231, the driving pressing block 232 and the driven pressing block 233 are respectively fixed in the opposite ends of the cylindrical connecting frame 231. Both the driving pressing block 232 and the driven pressing block 233 are elastic and have a ring structure. The diameters of the driving pressing block 232 and the driven pressing block 233 are slightly larger than the diameter of the cylindrical connecting frame 231, so that the driving pressing block 232 and the driven pressing block 233 can be directly inserted into the cylindrical connecting frame 231 to form an interference fit connection.

[0112] Furthermore, in embodiments of the present invention, see... Figures 12 to 14 One possible implementation of the cylindrical connecting frame 231 is that it includes an outer ring wall 2312 and an inner ring wall 2313 located inside the outer ring wall 2312, with the outer ring wall 2312 and the inner ring wall 2313 connected by multiple connecting ribs. The two opposite ends of the inner ring wall 2313 along the axial direction are located within the outer ring wall 2312, and respectively form cavities with the inner walls of the outer ring wall 2312 for mounting the driving pressing block 232 and the driven pressing block 233. The driving pressing block 232 and the driven pressing block 233 can be inserted into the cavities at both ends, forming an interference fit connection. Simultaneously, to improve connection stability, the driving pressing block 232 and the driven pressing block 233 can partially extend into the inner ring wall 2313 and connect with it. In some other embodiments of the present invention, the cylindrical connecting frame 231 can also be implemented by a columnar structure. The columnar structure has axially extending mounting grooves at both ends, and the driving pressing block 232 and the driven pressing block 233 are connected through the mounting grooves.

[0113] The second connecting part 22 includes a release operation part 251 and a driven shaft 252 disposed on the release operation part 251. The driven shaft 252 is rotatably connected to the driven pressure block 233. The release operation part 251 and the driven shaft 252 can be integrally formed or separate structures. When the release operation part 251 and the driven shaft 252 are separate structures, the driven shaft 252 can be fixedly connected to the release operation part 251 by injection molding insert.

[0114] In this embodiment of the invention, the first driving unit 11 includes a driving connecting surface and a driving connecting portion extending out of the driving connecting surface. The driving connecting portion may include, but is not limited to, a driving shaft 111 or an end-face gear disk. The function of the driving connecting surface can be referred to the first connecting wall 241 in the above embodiment. Further, to provide better support for the driving pressing block 232, refer to... Figure 9The outer periphery of the driving pressing block 232 is provided with a first annular rib 2322. Corresponding to the position of the first annular rib 2322 on the driving connecting surface, a second annular rib 2412 is provided. The second annular rib 2412 is fitted inside the first annular rib 2322. The diameter of the second annular rib 2412 is smaller than the diameter of the first annular rib 2322. Through the fitted engagement between the first annular rib 2322 and the second annular rib 2412, effective support is provided for the driving pressing block 232.

[0115] During installation, please refer to Figure 11 You can start along Figure 11 The solid straight arrow points in the direction of the second drive unit 21 on the roller brush assembly 20 to the first drive unit 11 on the floor brush body 10. For example, the first drive unit 11 may include a drive shaft 111, and the second drive unit 21 may be inserted into the drive shaft 111 along its axial direction. After the second drive unit 21 is connected to the first drive unit 11, it moves along... Figure 11 As indicated by the solid arc arrow, rotate the roller brush assembly 20 so that the second connecting part 22 engages with the first connecting part 12. For example, the first connecting part 12 can be a snap-fit ​​groove, and the second connecting part 22 can be an elastic snap-fit ​​buckle. The elastic snap-fit ​​buckle and the snap-fit ​​groove cooperate to connect the second connecting part 22 to the floor brush body 10, thereby completing the connection between the roller brush assembly 20 and the floor brush body 10.

[0116] The process of removing the roller brush assembly 20 from the floor brush body 10 is the reverse of the installation process described above. See below for further details. Figure 11 along Figure 11 As indicated by the dashed arc-shaped arrow, rotate the roller brush assembly 20 to disengage the second connecting part 22 from the first connecting part 12. Then, along... Figure 11 The direction of the dashed straight arrow in the middle is used to translate the roller brush assembly 20, so that the second drive part 21 is disengaged from the first drive part 11, thereby completing the disassembly of the roller brush assembly 20 from the floor brush body 10.

[0117] To further facilitate the installation of the roller brush body 23, in this embodiment of the invention, the axial lines of the cylindrical connecting frame 231, the second connecting part 22, and the first driving part 11 are located on the same straight line. The second connecting part 22 and the first driving part 11 can be used to position the cylindrical connecting frame 231, ensuring that the cylindrical connecting frame 231 and the first driving part 11 are on the same axial line. This facilitates the disassembly of the roller brush assembly 20 by first rotating it around the axial line and then translating it to one side. This allows for convenient rotational assembly and disassembly of the roller brush assembly 20 relative to the brush body 10 while ensuring the rolling operation of the roller brush body 23 within the roller brush assembly 20.

[0118] See also Figure 12 and Figure 14To avoid hard friction between the driven shaft 252 and the driven pressing block 233, in this embodiment of the invention, the driven pressing block 233 is provided with a transition groove 2331 at its center along the axial direction, and a transition hole is provided at the bottom of the transition groove 2331. A bearing component 2332 is provided inside the transition groove 2331, the outer ring of the bearing component 2332 is fixedly connected to the inner wall of the transition groove 2331, and the inner ring of the bearing component 2332 communicates with the transition hole. The driven shaft 252 is sleeved in the inner ring of the bearing component 2332 and is rotatably connected to the inner ring of the bearing component 2332. When the driven pressing block 233 and the driven shaft 252 rotate relative to each other, the bearing component 2332 makes the rotation smoother and avoids hard friction between the driven shaft 252 and the driven pressing block 233, thereby avoiding wear between the driven shaft 252 and the driven pressing block 233, effectively improving service life, and further reducing the cost and time of subsequent maintenance. The bearing component 2332 can be fixed to the inner wall of the adapter groove 2331 by injection molding insert, or it can be glued to the inner wall of the adapter groove 2331.

[0119] To prevent axial displacement of the driven shaft 252 relative to the bearing component 2332, a limiting structure 2521 is further provided on the end of the driven shaft 252 away from the release operation part 251. The limiting structure 2521 can be a limiting screw or a limiting stop at the end of the driven shaft 252. Taking a limiting stop as an example, see [reference needed]. Figure 14 The limiting block and the release operation part 251 are located on opposite sides of the bearing component 2332, that is, the limiting block is located on the right side of the bearing component 2332, and the release operation part 251 is located on the left side of the bearing component 2332. Due to the dual restriction of the release operation part 251 and the limiting block, the driven shaft 252 cannot be displaced axially relative to the bearing component 2332, thus preventing the driven shaft 252 from disengaging from the bearing component 2332.

[0120] Combination Figure 7 and Figure 8 To further protect the driven shaft 252 and the bearing component 2332, in this embodiment of the invention, a protective sleeve 26 is fixedly provided on the inner ring of the bearing component 2332, and the driven shaft 252 is sleeved inside the protective sleeve 26. The diameter of the protective sleeve 26 can be slightly larger than the diameter of the inner ring of the bearing component 2332, so that the protective sleeve 26 can be pressed onto the inner ring of the bearing component 2332, resulting in an interference fit connection between the protective sleeve 26 and the inner ring of the bearing component 2332. The driven shaft 252, sleeved inside the protective sleeve 26, connects to the bearing component 2332 through the protective sleeve 26, thereby reducing wear between the driven shaft 252 and the bearing component 2332, and achieving protection for both the driven shaft 252 and the bearing component 2332. It should be noted that... Figure 7 and Figure 8The structure shown is another implementation of the roller brush body 23 provided by the embodiment of the present invention. In the absence of structural conflicts, the arrangement of each component can be referenced to each other, which should not be regarded as an improper limitation of the embodiment of the present invention.

[0121] Furthermore, to prevent the brush bristles 234 from winding around the driven shaft 252 when the brush body 23 rotates, in this embodiment of the invention, see [reference needed]. Figure 12 and Figure 14 An anti-tangling cap 27 is fitted onto the driven shaft 252. The anti-tangling cap 27 prevents the brush bristles 234 from entering the driven shaft 252, thus avoiding them from becoming entangled on the driven shaft 252. The anti-tangling cap 27 can be positioned between the bearing member 2332 and the release operation part 251. The bearing member 2332 is located between the anti-tangling cap 27 and the limiting block. The release operation part 251, the anti-tangling cap 27, and the limiting block further restrict the axial direction of the driven shaft 252, preventing axial displacement of the driven shaft 252 relative to the bearing member 2332.

[0122] See Figure 15 To prevent dirt and wastewater from being thrown outwards during the operation of the roller brush 23, thus causing secondary pollution, in this embodiment of the invention, the roller brush assembly 20 further includes a roller brush cover 24. The roller brush cover 24 is detachably connected to the brush body 10 and is adapted to the outer surface of the roller brush 23, covering it. In this embodiment, the roller brush cover 24 does not require a first connecting wall 241 and a second connecting wall 242; these are used to shield the roller brush 23. The roller brush cover 24 can cover the top of the roller brush 23, and the roller brush cover 24 and the cleaning surface enclose a space for the roller brush 23 to roll. The roller brush cover 24 prevents the roller brush 23 from throwing dirt and wastewater outwards.

[0123] For easier disassembly and assembly of the roller brush cover 24, please refer to [link / reference]. Figure 15 and Figure 16 The roller brush cover 24 is provided with a second hand grip structure 50 for hand holding, which allows for the assembly and disassembly of the roller brush cover 24 from the floor brush body 10. The second grip structure 50 increases the contact area between the roller brush cover 24 and the user's hand, making it easier for the user to grasp the roller brush cover 24, apply pressure to it, and facilitate the assembly and disassembly of the roller brush cover 24.

[0124] In one embodiment of the invention, the second gripping structure 50 can be implemented as a handle with a receiving groove on the side of the brush cover 24 facing away from the brush body 23. The user's fingers can be inserted into the receiving groove, making it easier to grip the second gripping structure 50 and apply force more readily.

[0125] One way to connect the roller brush cover 24 is, see [link to previous section] Figure 15 and Figure 16 The floor brush body 10 is provided with a first locking connection part 13. The roller brush cover 24 is provided with a second locking connection part 243 that cooperates with the first locking connection part 13. The second locking connection part 243 is connected to the first locking connection part 13 and locks the relative position between the roller brush cover 24 and the floor brush body 10. It should be noted that in Figure 16 In the middle, the second locking connection part 243 provided on the roller brush cover 24 can be provided on the inner surface of the roller brush cover 24, that is, on the side of the roller brush cover 24 facing the roller brush body 23. Therefore, in the attached Figure 16 Not shown in the diagram. The first locking connection 13 and the second locking connection 243 can be referenced. Figure 2 and Figure 3 The implementation method is as follows. Specifically, the first locking connection part 13 and the second locking connection part 243 can be implemented in various ways. For example, one of the first locking connection part 13 and the second locking connection part 243 can be a spring-loaded buckle, and the other a slot. Alternatively, one of the first locking connection part 13 and the second locking connection part 243 can be a spring-loaded latch, and the other a locking hole. After the first locking connection part 13 and the second locking connection part 243 are connected, displacement of the roller brush cover 24 relative to the floor brush body 10 can be prevented. When disassembling the roller brush assembly 20 from the floor brush body 10, refer to... Figure 16 First, remove the roller brush cover 24 from the main body of the floor brush 10. Then, refer to... Figure 11 Then, remove the roller brush body 23 from the brush body 10. During installation, the roller brush body 23 can be installed on the brush body 10 first, and then the roller brush cover 24 can be installed. Of course, when cleaning and maintenance of the roller brush body 23 is required, it is not necessary to remove the roller brush cover 24 from the brush body 10; only the roller brush body 23 needs to be removed from the roller brush cover 24.

[0126] Another connection method for the roller brush cover 24 is that the roller brush cover 24 is detachably connected to the roller brush body 23, and the roller brush cover 24 is adapted to the outer surface of the roller brush body 23 and covers the roller brush body 23. One end of the roller brush cover 24 can be snapped onto the release operation part 251, and the other end extends along the axial direction of the roller brush body 23, thereby covering the top of the roller brush body 23. To further ensure the connection stability of the roller brush cover 24, the roller brush cover 24 can also overlap the floor brush body 10 and the first drive part 11, thereby providing multi-point support for the roller brush cover 24. When removing the roller brush assembly 20 from the floor brush body 10, see... Figure 16 First, remove the roller brush cover 24 from the roller brush body 23. Then, refer to... Figure 11Then remove the roller brush body 23 from the floor brush body 10. During installation, the roller brush body 23 can be installed on the floor brush body 10 first, and then the roller brush cover 24 can be installed. Alternatively, the roller brush body 23 and the roller brush cover 24 can be removed from the floor brush body 10 together first, and then the roller brush cover 24 can be removed from the roller brush body 23.

[0127] It should be noted that the connection method of the roller brush cover 24 can be implemented individually or in combination. That is, the roller brush cover 24 is detachably connected to the main body of the floor brush 10 and also detachably connected to the roller brush body 23. It can be set according to different needs, and the embodiments of the present invention do not make specific limitations.

[0128] In one embodiment of the present invention, the first driving unit 11 and the second driving unit 21 are implemented as follows: See Figure 11 and Figure 13 The first driving unit 11 includes a driving shaft 111, and a first driving engagement portion is provided circumferentially on the outer wall of the driving shaft 111. A through hole 2321 is provided at the center of the driving pressing block 232. The second driving unit 21 includes a first driving hole 2311 provided on the cylindrical connecting frame 231, and a second driving engagement portion that cooperates with the first driving engagement portion is provided on the inner wall of the first driving hole 2311. The driving shaft 111 can sequentially pass through the connecting hole 2411 and the through hole 2321 and be fitted into the first driving hole 2311. The first driving engagement portion engages with the second driving engagement portion so that the driving shaft 111 can drive the cylindrical connecting member to rotate circumferentially along the driving shaft 111. Further, the first driving hole 2311 can be provided on the inner annular wall 2313 of the cylindrical connecting frame 231.

[0129] The first and second drive engagement parts can be implemented in various ways. For example, the first drive engagement part can be a plurality of protruding structures arranged circumferentially along the drive shaft 111, and the second drive engagement part can be a groove-shaped structure arranged on the inner wall of the first drive hole 2311. Of course, the protruding structures can also be arranged on the first drive hole 2311, and the groove-shaped structure can be arranged on the drive shaft 111. When the drive shaft 111 is fitted into the first drive hole 2311, the protruding structures and the groove-shaped structure engage. When the drive shaft 111 rotates, it can drive the cylindrical connector to rotate.

[0130] Another implementation of the first driving part 11 and the second driving part 21 is as follows: the second driving part 21 includes a second driving hole located at the center of the driving pressing block 232, and a third driving engaging part on the inner wall of the second driving hole for use with the first driving engaging part; the driving shaft 111 can pass through the connecting hole 2411 and be fitted into the second driving hole, and the first driving engaging part and the third driving engaging part engage, so that the driving shaft 111 drives the cylindrical connecting member to rotate circumferentially along the driving shaft 111 through the driving pressing block 232. The third driving engaging part is a structure suitable for cooperating with the first driving engaging part. Depending on the shape of the first driving engaging part, the third driving engaging part can be a groove-shaped structure or a protruding structure.

[0131] It should be noted that the two implementation methods of the first driving part 11 and the second driving part 21 described above can be implemented individually or in combination. Simultaneously, the first driving engagement part can also be provided with protruding structures and grooved structures at intervals, and the second driving engagement part and the third driving engagement part can be provided with corresponding cooperating structures. In this embodiment of the invention, no specific limitations are made. Furthermore, the first driving part 11 and the second driving part 21 can also be implemented using an end-face gear disk structure.

[0132] refer to Figure 8 and Figure 10 In one embodiment of the present invention, the roller brush strip 234 can be implemented in such a way that the roller brush strip 234 extends radially along the cylindrical connecting frame 231, and the length of the roller brush strip 234 can be set according to different cleaning needs.

[0133] See Figure 14 In this embodiment of the invention, there are very few components between the cylindrical connecting frame 231 and the release operation part 251, and all of them are located within the cylindrical connecting frame 231. Therefore, the gap between the cylindrical connecting frame 231 and the release operation part 251 is very small. The release operation part 251 can be regarded as the edge of the floor brush body 10, or the range covered by the release operation part 251 is the cleaning edge of the floor brush. Since the cylindrical connecting frame 231 can be very close to the release operation part 251, the roller brush strips 234 provided on the cylindrical connecting frame 231 can clean corners and other hard-to-reach areas, effectively preventing dirt residue after cleaning the corner areas. To further increase the cleaning range of the roller brush body 23, in this embodiment of the invention, the release operation part 251 can be set to a minimum thickness while satisfying the requirement of supporting the cylindrical connecting frame 231, so that the roller brush strips 234 can be closer to the cleaning edge.

[0134] Another way to increase the cleaning range of the roller brush 23 is to refer to... Figure 8At least one end of the roller brush sliver 234 located away from the first drive unit 11 can extend beyond the cylindrical connecting frame 231 in the axial direction. A longer roller brush sliver 234 can be selected, extending radially along the cylindrical connecting frame 231. Simultaneously, the release operation part 251 is relatively thin, allowing the roller brush sliver 234, under the influence of the roller brush body 23's gravity during cleaning, to extend beyond the cylindrical connecting frame 231 and outwards towards the release operation part 251. This increases the cleaning range of the roller brush body 23, achieving effective cleaning of corner areas.

[0135] In this embodiment of the invention, the floor brush can be applied to a mobile device, which includes, but is not limited to, cleaning machines, robotic vacuum cleaners, and other similar devices. Accordingly, this embodiment of the invention also provides a mobile device, see [link to relevant documentation]. Figure 4 The movable device includes a device body 30 and a floor brush as described in the above embodiment, connected to the device body 30. To facilitate the movement of the floor brush, the floor brush body 10 is also provided with multiple travel wheels. The device body 30 is provided with a water supply system and a suction system for cleaning the floor. The floor brush includes a floor brush body 10 and a roller brush assembly 20. The floor brush is connected to the device body 30 via the floor brush body 10. A first drive portion 11 and a first connecting portion 12 are respectively provided at opposite ends of the floor brush body 10. At opposite ends of the roller brush assembly 20 along the axial direction, a second drive portion 21 is provided for use with the first drive portion 11, and a second connecting portion 22 is provided for use with the first connecting portion 12. The second drive portion 21 is detachably connected to the first drive portion 11, and the second connecting portion 22 is detachably connected to the first drive portion 11.

[0136] The second connecting part 22 is provided with a first hand-held structure 40 for hand gripping, and the hand grips the first hand-held structure 40 to drive the roller brush body 23 to move.

[0137] The technical solution provided in this embodiment of the invention is that both ends of the roller brush body 23 are detachably connected to the floor brush body 10. A first hand-held structure 40 is provided on the roller brush body 23 for the user to hold, which makes it convenient for the user to apply force to the roller brush body 23 and to detach and install the roller brush body 23 from the floor brush body 10, thereby reducing the user's operating difficulty and maintenance time.

[0138] Further, see Figures 1 to 3 The present invention also provides another type of floor brush, including: a floor brush body 10 and a roller brush assembly 20.

[0139] The floor brush body 10 has a first driving part 11 and a first connecting part 12 at opposite ends. See also Figure 5 and Figure 6The roller brush assembly 20 includes a roller brush body 23 and a roller brush cover 24. The roller brush body 23 has a second drive unit 21 that cooperates with the first drive unit 11, and the roller brush cover 24 has a second connecting part 22 that cooperates with the first connecting part 12. The first connecting part 12 and the second connecting part 22 cooperate to mount the roller brush assembly 20 onto the floor brush body 10. The second drive unit 21 is detachably connected to the first drive unit 11, and the second connecting part 22 is detachably connected to the first connecting part 12.

[0140] The second connecting portion 22 on the roller brush cover 24 is provided with a third hand-holding structure for gripping. The third hand-holding structure is used to disengage the second connecting portion of the roller brush assembly 20 from the first connecting portion of the floor brush body. The implementation of the third hand-holding structure can refer to or draw on the implementation of the first hand-holding structure 40 in the above embodiments, and will not be repeated here.

[0141] See Figure 3 To facilitate user assembly and disassembly, in this embodiment of the invention, the first driving part 11 and the second driving part 21, as well as the first connecting part 12 and the second connecting part 22, can be snap-fitted together. This facilitates user assembly and disassembly. For example, the first driving part 11 may include a motor with a drive shaft 111, and the second driving part 21 can be inserted into the drive shaft 111 along its axial direction. The first connecting part 12 can be a snap-fit ​​groove, and the second connecting part 22 can be an elastic snap-fit ​​buckle. The elastic snap-fit ​​buckle engages with the snap-fit ​​groove to connect the second connecting part 22 to the floor brush body 10.

[0142] Furthermore, the roller brush assembly 20 is disassembled by first rotating it about the axial line and then translating it to one side. One possible method is to refer to... Figure 2 along Figure 2 Rotate the brush assembly 20 in the direction indicated by the solid arrow to disengage the second connecting part 22 from the first connecting part 12. Then, see... Figure 3 , and then along Figure 3 The solid arrow in the middle moves the second driving part 21, causing it to disengage from the first driving part 11, thereby completing the disassembly of the roller brush assembly 20 from the floor brush body 10. Furthermore, in this embodiment of the invention, the floor brush can be implemented in various ways, which will be described separately below through specific embodiments. It should be noted that the related technical features and their connection methods in each embodiment can be referenced and learned from each other without conflict. The structures shown in the accompanying drawings are merely exemplary and should not be construed as improper limitations on the embodiments of the present invention.

[0143] One feasible method for using floor brushes is to combine... Figures 1 to 3 See Figure 5 and Figure 6The roller brush assembly 20 includes a roller brush body 23 and a roller brush cover 24. A second driving portion 21 and an elastic connecting assembly 25 are respectively provided at opposite ends of the roller brush body 23 along the axial direction. A second connecting portion 22 is provided on the roller brush cover 24. Along the length direction (in this embodiment, the length direction of the roller brush cover 24 is the axial direction of the roller brush body 23), a first connecting wall 241 and a second connecting wall 242 are respectively provided at opposite ends of the roller brush cover 24. The first connecting wall 241 and the second connecting wall 242 form an accommodating space. A connecting hole 2411 is provided on the first connecting wall 241, and an annular groove 2421 is provided on the second connecting wall 242.

[0144] The roller brush body 23 is rotatably connected within the accommodating space, wherein the second drive unit 21 abuts against the first connecting wall 241 and is connected to the first drive unit 11 through the connecting hole 2411. The elastic connecting assembly 25 abuts against the second connecting wall 242 and is partially engaged within the annular groove 2421.

[0145] The roller brush cover 24 is adapted to the outer surface of the roller brush body 23 and covers the roller brush body 23. The roller brush cover 24 can cover the upper part of the roller brush body 23, and the roller brush cover 24 and the cleaning surface form a space for the roller brush body 23 to roll. The roller brush cover 24 can prevent the roller brush body 23 from throwing dirt, sewage and other substances to the outer periphery.

[0146] During installation, please refer to Figure 5 First, the roller brush body 23 can be connected to the receiving space on the roller brush cover 24. Specifically, first, the second drive part 21 on the roller brush body 23 is abutted against the first connecting wall 241; then, the elastic connecting component 25 is pressed, or the elastic connecting component 25 is squeezed through the second connecting wall 242, to create a channel that allows the roller brush body 23 to enter the receiving space; then, along... Figure 5 As indicated by the dashed arrow, the roller brush body 23 is placed into the receiving space. When the elastic connecting component 25 moves onto the annular groove 2421, the force applied to the elastic connecting component 25 disappears, and part of the elastic connecting component 25 springs in and engages within the annular groove 2421. The state in which the roller brush body 23 and the roller brush cover 24 are connected can be seen in [reference needed]. Figure 6 .

[0147] At this point, the roller brush body 23 and the roller brush cover 24 can be considered as a single unit, thus forming the roller brush assembly 20. The process of installing the roller brush assembly 20 onto the floor brush body 10 is as follows, see [link to documentation]. Figure 3 First along Figure 3 The direction of the dashed arrow indicates the connection between the second drive unit 21 and the first drive unit 11. For example, the first drive unit 11 may include a drive shaft 111, and the second drive unit 21 may be inserted into the drive shaft 111 along its axial direction. See [link to image / description] for the state after the second drive unit 21 and the first drive unit 11 are connected. Figure 2Then, along Figure 2 As indicated by the dashed arrow, rotate the roller brush assembly 20 so that the second connecting part 22 engages with the first connecting part 12. For example, the first connecting part 12 can be a snap-fit ​​groove, and the second connecting part 22 can be an elastic snap-fit ​​buckle. The elastic snap-fit ​​buckle engages with the snap-fit ​​groove to connect the second connecting part 22 to the floor brush body 10, thus completing the connection between the roller brush assembly 20 and the floor brush body 10.

[0148] The process of removing the roller brush assembly 20 from the floor brush body 10 is the reverse of the installation process described above. See [link to relevant documentation]. Figure 2 Along Figure 2 Rotate the brush assembly 20 in the direction indicated by the solid arrow to disengage the second connecting part 22 from the first connecting part 12. Then, see... Figure 3 , and then along Figure 3 The direction of the solid arrow in the middle is used to translate the second drive unit 21, so that the second drive unit 21 is disengaged from the first drive unit 11, thereby completing the disassembly of the roller brush assembly 20 and the floor brush body 10.

[0149] The process of removing the roller brush body 23 from the roller brush cover 24 is as follows: See Figure 6 ,along Figure 6 In the direction indicated by the solid arrow, press the elastic connecting component 25 so that it disengages from the annular groove 2421, creating a channel for the brush body 23 to exit from the receiving space; then, see... Figure 5 along Figure 5 As indicated by the solid arrow, the end of the roller brush 23 is moved out of the accommodating space. At this time, the second drive part 21 on the roller brush 23 is disengaged from the first connecting wall 241, and the roller brush 23 can be moved out horizontally, so that the roller brush 23 can be cleaned and maintained.

[0150] To further facilitate the installation of the roller brush body 23, in this embodiment of the invention, see below. Figure 6 The axial lines of the roller brush body 23, the first connecting wall 241, the second connecting wall 242, and the first drive unit 11 are all on the same straight line. The roller brush body 23 can be positioned by the annular groove 2421 and the first connecting wall 241, so that the roller brush body 23, the roller brush cover 24, and the first drive unit 11 are on the same axial line. This makes it convenient to disassemble the roller brush assembly 20 by first rotating it around the axial line and then moving it to one side. This facilitates the rotation and disassembly of the roller brush assembly 20 relative to the brush body 10, while also ensuring the rolling operation of the roller brush body 23 in the roller brush assembly 20.

[0151] The technical solution adopted in this invention will be described below in conjunction with specific application scenarios to aid understanding.

[0152] Application Scenario 1

[0153] After the cleaning machine finishes its cleaning operation, the user needs to clean the main body 10 of the floor brush, including cleaning the roller brush 23 on the floor brush.

[0154] See Figure 2 First, the roller brush assembly 20 is unlocked. The first locking connection part 13 is a locking hole, and the second locking connection part 243 is a spring latch. The user presses the spring latch, and the spring latch disengages from the limit of the locking hole, thus unlocking the roller brush assembly 20. Then, the user continues to rotate the roller brush assembly 20 axially. Figure 2 In the direction indicated by the solid arrow, rotate the roller brush assembly 20 to disengage the second connecting part 22 from the first connecting part 12, thus unlocking the non-drive side of the roller brush assembly 20. Then, see... Figure 3 , and then along Figure 3 The solid arrow in the middle indicates that the roller brush assembly 20 is moved horizontally, causing the second drive unit 21 to disengage from the first drive unit 11, thereby completing the disassembly of the roller brush assembly 20 from the floor brush body 10. This facilitates cleaning of the floor brush body 10 and the roller brush assembly 20 by the user.

[0155] To further enhance the cleaning effect, the user can choose to remove the roller brush body 23 from the roller brush assembly 20. Remove the roller brush body 23 from the roller brush cover 24, see [link to relevant documentation]. Figure 6 ,along Figure 6 In the direction indicated by the solid arrow, press the elastic connecting component 25 so that it disengages from the annular groove 2421, creating a channel for the brush body 23 to exit from the receiving space. Then, see... Figure 5 along Figure 5 As indicated by the solid arrow, the end of the roller brush 23 is moved out of the accommodating space. At this time, the second drive part 21 on the roller brush 23 is disengaged from the first connecting wall 241, and the roller brush 23 can be moved out horizontally, so that the roller brush 23 can be cleaned and maintained.

[0156] After cleaning and maintenance are completed, the roller brush body 23 can be installed on the roller brush cover 24 and the roller brush assembly 20 can be installed on the floor brush body 10 in reverse order of the above process.

[0157] Application Scenario 2

[0158] After the cleaning machine finishes its cleaning operation, the user needs to clean the main body 10 of the floor brush, including cleaning the roller brush 23 on the floor brush.

[0159] First, see Figure 16 First, remove the roller brush cover 24 from the floor brush body 10. Specifically, the user pulls the roller brush cover 24 forcefully, and the second locking connection part 243 on the roller brush cover 24 separates from the first locking connection part 13, thus removing the roller brush cover 24 from the floor brush body 10.

[0160] Then, see Figure 11 along Figure 11 As indicated by the dashed arc-shaped arrow, rotate the roller brush assembly 20 to disengage the second connecting part 22 from the first connecting part 12. Then, along... Figure 11 The direction of the dashed straight arrow in the middle moves the roller brush assembly 20 so that the second drive part 21 is disengaged from the first drive part 11, thereby completing the disassembly of the roller brush assembly 20 from the floor brush body 10, and the roller brush body 23 can be cleaned and maintained.

[0161] After cleaning and maintenance are completed, the roller brush assembly 20 can be installed on the floor brush body 10 in the reverse order of the above process, and then the roller brush cover 24 can be installed on the floor brush body 10.

[0162] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
