[0002] As people's living standards continue to improve, cleaning equipment such as sweepers and floor scrubbers have become indispensable appliances in people's daily lives.

[0003] In daily life, it is necessary not only to sweep away the garbage on the surface to be cleaned, but also to perform wet cleaning on the surface to achieve efficient cleaning of stubborn stains. In order to meet this cleaning need, the cleaning equipment needs to be equipped with two roller brushes: one with stiff bristles for dry cleaning and the other with soft bristles for wet cleaning. Different cleaning needs can be met by changing the roller brushes. However, changing the roller brushes is cumbersome, wastes time, and affects cleaning efficiency. Summary of the Invention

[0065] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0066] Example 1

[0067] This embodiment provides a roller brush mechanism 100, such as Figures 1 to 2 As shown, it includes a roller 1 and at least one bristle assembly 2. The roller 1 has a cylindrical structure to facilitate rotation on the surface to be cleaned. The interior of the roller 1 has a hollow cavity 11 that extends through the roller 1 along its axial direction. The axial direction of the roller 1 is as follows... Figure 1 As shown in direction a, the radial direction of roller 1 is as follows: Figure 2 The direction b is shown in the middle.

[0068] Please see Figures 3 to 5 The brush assembly 2 includes a support 21 movably mounted on the roller 1, and first bristles 22 and second bristles 23 mounted on the support 21. The first bristles 22 and second bristles 23 have different hardness to meet different cleaning needs. The first bristles 22 can be soft and the second bristles 23 can be hard; or, the first bristles 22 can be hard and the second bristles 23 can be soft. The hard bristles are used for sweeping on carpets and other surfaces awaiting cleaning, while the soft bristles are used for mopping on floors and other surfaces awaiting cleaning. The arrangement of the first bristles 22 and second bristles 23 increases the applicability of the roller brush mechanism 100.

[0069] It should be noted that the first bristle 22 and the second bristle 23 refer to a cleaning unit that includes multiple brushes and can be used for cleaning. The number of bristles can be set according to actual needs. The method by which the first bristle 22 and the second bristle 23 are fixed on the bracket 21 is existing technology and will not be described in detail here.

[0070] The number of bristle components 2 can be one, two, three, four, etc., which will not be listed here. When the number of bristle components 2 is at least two, the at least two bristle components 2 can be equally spaced on the roller 1, but it is not limited to this. They can also be spaced on the roller 1 according to actual needs.

[0071] In this embodiment, one of the first bristles 22 and the second bristles 23 is located outside the roller 1, and the other is located inside the hollow cavity 11. When the first bristle 22 or the second bristle 23 is located outside the roller 1, it can directly contact the surface to be cleaned to clean it. The bristle located inside the hollow cavity 11 does not work. This arrangement is simple in structure and makes full use of the space of the roller 1, thus miniaturizing the roller brush mechanism 100.

[0072] The bracket 21 is a closed loop and is fitted onto the side wall of the roller 1. Specifically, the roller 1 is provided with a mounting component 3 corresponding to the bristle assembly 2, which is used to mount the bristle assembly 2 onto the roller 1.

[0073] Priority, such as Figure 3 As shown, the mounting assembly 3 includes a first through groove 31 on the outer wall of the roller 1 and a second through groove 32 on the inner wall of the roller 1. The first through groove 31 is formed by recessing from the outer wall surface of the roller 1 radially inward. The second through groove 32 is formed by recessing from the inner wall surface of the roller 1 radially inward. The number of mounting assemblies 3 is consistent with the number of bristle assemblies 2.

[0074] The bracket 21 is slidably fitted into the first through groove 31 and the second through groove 32. The first bristles 22 and the second bristles 23 are located outside their respective through grooves. That is, when the first bristles 22 are outside the roller 1, they are also outside the first through groove 31. This avoids a reduction in the contact area and force applied to the surface to be cleaned by the first bristles 22 being partially inside the first through groove 31, thus preventing a decrease in the cleaning efficiency of the first bristles 22. Similarly, when the second bristles 23 are outside the roller 1, they are also outside the first through groove 31 to improve their cleaning efficiency.

[0075] The first through groove 31 and the second through groove 32 are connected so that the bracket 21 is fitted into a closed loop on the side wall of the roller 1. Regarding the formation of the closed loop of the bracket 21, it can be fixed by connecting the two ends after it is fitted into the side wall of the roller 1.

[0076] like Figure 5 As shown, along a direction perpendicular to the length of the first bristle 22 or the second bristle 23, the two outer side walls of the support 21 are respectively provided with an outwardly protruding first outer edge 211 and a second outer edge 212. The support 21 is fitted into the first through groove 31 and the second through groove 32 through the first outer edge 211 and the second outer edge 212. The arrangement of the first outer edge 211 and the second outer edge 212 improves the stability of the support 21 on the side wall of the roller brush.

[0077] Preferably, such as Figure 5As shown, the support 21 includes a first segment 213 and a second segment 214, which are connected end-to-end. First bristles 22 and second bristles 23 are respectively disposed on the first segment 213 and the second segment 214. The first segment 213 and the second segment 214 are spirally distributed in the same direction on the roller 1. Correspondingly, the first through groove 31 and the second through groove 32 are spirally distributed. Clearly, the spiral distribution of the first through groove 31 and the second through groove 32, when the support 21 is disposed within them, achieves the same spiral distribution. Furthermore, the spiral distribution of the first segment 213 and the second segment 214 on the roller 1 increases the contact area between the first bristles 22 or the second bristles 23 located outside the roller 1 and the surface to be cleaned, reducing vibration during the rotation of the roller brush mechanism 100 and further improving the cleaning efficiency of the roller brush mechanism 100. The specific spiral pattern and spiral degree of the first through groove 31 and the second through groove 32 are not specifically limited here; they can be set according to actual needs.

[0078] As described above, one of the first bristles 22 and the second bristles 23 is located outside the roller 1, and the other is located inside the hollow cavity 11. That is, when the first bristle 22 is outside the roller 1, the second bristle 23 is inside the hollow cavity 11, or vice versa. In this embodiment, the bracket 21 moves on the roller 1 to switch the positions of the first bristles 22 and the second bristles 23 on the roller 1 to either outside the roller 1 or inside the hollow cavity 11. By switching the positions of the first bristles 22 and the second bristles 23 on the roller 1 using the bracket 21, the bristles located outside the roller 1 and in contact with the surface to be cleaned can be switched according to cleaning needs.

[0079] The bracket 21 slides within the first through groove 31 and the second through groove 32 to switch the positions of the first bristles 22 and the second bristles 23 on the roller 1, thereby changing the type of bristles located outside the roller 1. This eliminates the need to change the roller brush, meeting different cleaning needs, saving time, and simplifying operation. As described above, the bracket 21 is fitted into the first through groove 31 and the second through groove 32 via the first outer edge 211 and the second outer edge 212. The arrangement of the first outer edge 211 and the second outer edge 212 also improves the sliding stability of the bracket 21 within the first through groove 31 and the second through groove 32, preventing the bracket 21 from leaving the first through groove 31 or the second through groove 32 during sliding. Furthermore, the first through groove 31 and the second through groove 32 are distributed along the same spiral, so that when the first bristles 22 and the second bristles 23 switch positions, the first section 213 and the second section 214 of the bracket 21 can fit closely within the first through groove 31 and the second through groove 32.

[0080] Please see Figure 2 , Figure 4 , Figures 6 to 8The roller brush mechanism 100 also includes a switching assembly 4 disposed on the roller 1. The switching assembly 4 is used to drive the support 21 to slide within the first through groove 31 and the second through groove 32. The switching assembly 4 includes a sliding member 41 and a stop member 42, and the stop member 42 drives the sliding member 41 to slide within the hollow cavity 11.

[0081] Specifically, the sliding member 41 includes a main body 411 and at least one sliding protrusion 412 provided on the outer peripheral wall of the main body 411. The sliding protrusion 412 slides on the inner wall of the roller 1, thereby realizing the sliding member 41 sliding within the hollow cavity 11. In this embodiment, the inner wall of the roller 1 is provided with a guide groove 12 for the sliding protrusion 412 to slide, so as to improve the stability and smoothness of the sliding protrusion 412 sliding on the inner wall of the roller 1. The main body 411 and the sliding protrusion 412 can be integrally formed to improve the strength and service life of the sliding member 41.

[0082] In this embodiment, the first end of the slider 41 is connected to the bracket 21 or the bristles located in the hollow cavity 11. Specifically, along the radial direction of the roller 1, the outer wall of the slider 41 is provided with a recessed area 413 corresponding to the number of brackets 21. The recessed area 413 is provided with a step (not shown). Along the axial direction of the roller 1, the end of the first bristle 22 or the second bristle 23 located in the hollow cavity 11 abuts against the step surface and is located in the recessed area 413. When the slider 41 slides in the hollow cavity 11, the step drives the first bristle 22 or the second bristle 23 that abuts against it to slide synchronously in the hollow cavity 11, so that the slider 41 slides in the first through groove 31 and the second through groove 32, thereby switching the position of the first bristle 22 and the second bristle 23 on the roller 1. The recessed area 413 is formed between two sliding protrusions 412, and the number of sliding protrusions 412 is the same as the number of brackets 21.

[0083] The sliding of the sliding member 41 within the hollow cavity 11 is driven by the abutment member 42. The abutment member 42 has a first state and a second state. In the first state, the abutment member 42 is located within the hollow cavity 11, and its first end is detachably connected to the first end of the sliding member 41. In the second state, the abutment member 42 may be located outside the roller 1, and its first end abuts against or is detachably connected to the second end of the sliding member 41 to push the sliding member 41 to slide within the hollow cavity 11, thereby driving the support 21 to slide in conjunction.

[0084] Specifically, such as Figure 7 and Figure 8 As shown, the first end 414 of the slider 41 extends from the first end 15 of the roller 1 into the hollow cavity 11, for example along... Figure 7In the direction of A, the first end 414 of the sliding member 41 extends into the hollow cavity 11 of the roller 1, and the first end 421 of the abutment member 42 extends from the second end 14 of the roller 1 into the hollow cavity 11, for example along... Figure 7 The abutment 42 extends into the hollow cavity 11 in the B direction and can be connected to the first end 414 of the sliding member 41. At this time, the abutment 42 is in the first state. When the abutment 42 is pulled out from the hollow cavity 11 from the second end 14 of the roller 1, and the first end 421 of the abutment 42 abuts against or connects to the second end 415 of the sliding member 41, under the drive of external force, the abutment 42 extends into the hollow cavity 11 to push the sliding member 41 from the first end 15 of the roller 1 to the second end 14 of the roller, that is, in Figure 7 Sliding along direction A, the step of the recessed area 413 of the slider 41 abuts against the bristles located in the hollow cavity 11, thereby driving the bristles and the support 21 to slide, thus completing the position switching of the first bristle 22 and the second bristle 23 on the roller 1.

[0085] The roller brush mechanism 100 also includes a drive mechanism having a drive end 5 and an end cover 6. The drive end 5 and the end cover 6 are disposed opposite each other at both ends of the roller 1 along its axial direction and are both located outside the roller 1. The drive end 5 includes a motor 51, a gearbox 52 connected to the motor 51, and an output shaft 53 connected to the gearbox 52. The drive end 5 is used to provide the driving force for rotating the roller 1. It is an existing structure and will not be described in detail here.

[0086] In the first state, the output shaft 53 of the drive end 5 is detachably connected to the second end 415 of the slider 41, meaning the output shaft 53 and the second end 415 of the slider 41 are detachably connected. The end cover 6 is fixedly connected to the second end 422 of the abutment 42. At this time, the first end 414 of the slider 41 and the first end 421 of the abutment 42 are detachably and rotatably connected. Specifically, the second end 415 of the slider 41 is inserted into the drive end 5 along the axial direction of the roller 1, thereby enabling the drive end 5 to drive the slider 41 to rotate synchronously. The first end 414 of the slider 41 and the first end 421 of the abutment 42 are in a radial clearance fit with the roller 1 and are inserted into the roller 1 along the axial direction, so that the slider 41 and the abutment 42 can interfere along the axial direction of the roller 1, but do not interfere along the radial direction of the roller 1, thereby allowing the slider 41 to rotate relative to the abutment 42.

[0087] The rotation of the sliding member 41 is driven by the drive end 5, and the sliding protrusion 412 of the sliding member 41 is inserted into the guide groove 12 on the inner wall of the roller 1. When the sliding member 41 rotates, it drives the bracket 21 and the roller 1 to rotate relative to the abutment 42 and the end cover 6, so that the bristles located outside the roller 1 can clean the surface to be cleaned.

[0088] Under the action of external force, the end cap 6 and the abutment 42 separate from the roller 1, for example in Figure 7 In the process, the end cap 6 and the abutment 42 are removed from the roller 1 along direction A. The abutment 42 is in the second state. The roller 1 and the second end 415 of the slider 41 are separated from the drive end 5. The first end 421 of the abutment 42 is engaged with the second end 415 of the slider 41. The abutment 42 is driven to push the slider 41 to slide from the first end 15 of the roller 1 to the second end 14 of the roller 1, driving the bracket 21 to slide on the roller 1. The positions of the first bristles 22 and the second bristles 23 on the roller 1 are switched. Then, the roller 1 is rotated 180° and the first end 15 and the second end 14 of the roller 1 are swapped. At this time, the first end 414 and the second end 415 of the slider 41 are also swapped. The first end (i.e. the original second end) formed after the slider 41 is swapped is engaged with the drive end 5, and the drive end 5 and the slider 41 are connected. The abutment 42 is switched to the first state so that the bristles can be switched and cleaning work can be performed.

[0089] Please see Figure 2 , Figure 7 and Figure 9 In other embodiments, the drive mechanism further includes a limiting component, which includes a first limiting part 71 and a second limiting part 72. The first limiting part 71 and the second limiting part 72 are detachably disposed at both axial ends of the roller 1. For example, the first limiting part 71 is disposed at the first end 15 of the roller 1, and the second limiting part 72 is disposed at the second end 14 of the roller 1. The first limiting part 71 and the second limiting part 72 have the same structure, both being hollow annular structures. In order to improve the fit between the first limiting part 71 and the first end 15 of the roller 1, and the fit stability between the second limiting part 72 and the second end 14 of the roller 1, a plurality of positioning grooves 13 are provided at both ends of the roller 1. The first limiting part 71 is provided with a protrusion 73 corresponding to the positioning groove 13 on the side facing the roller 1. The connection between the first limiting part 71 and the roller 1 is realized through the insertion and engagement of the protrusion 73 and the positioning groove 13. Similarly, the second limiting part 72 is also provided with a protrusion 73 on the side facing the roller 1. The connection between the second limiting part 72 and the roller 1 is achieved by the insertion and cooperation of the protrusion 73 and the positioning groove 13.

[0090] As described above, the drive end 5 of the drive mechanism drives the roller 1 to rotate. Due to the cooperation of the protrusion 73 and the positioning groove 13, the first limiting part 71 and the second limiting part 72 rotate synchronously. In order to improve the rotational stability of the first limiting part 71 and the second limiting part 72, the first limiting part 71 and the second limiting part 72 are respectively sleeved on the drive end 5 and the abutment 42 by bearings 8.

[0091] The outer ends of the first limiting part 71 and the second limiting part 72, which are far apart from each other, abut against the inner walls of the outer shell and the end cover 6 of the drive mechanism, respectively. The first limiting part 71 and the second limiting part 72 restrict the axial movement of the roller 1 and improve the stability of the rotation of the roller 1.

[0092] In addition, the roller brush mechanism 100 also includes a third bristle (not shown) to assist the first bristle 22 or the second bristle 23 in cleaning. The third bristle is disposed on the outer surface of the roller 1 and avoids the distribution of the first bristle 22 or the second bristle 23 located outside the roller 1. The length of the third bristle is less than the length of either the first bristle 22 or the second bristle 23, so as not to affect the cleaning function of the first bristle 22 or the second bristle 23.

[0093] In summary, the roller brush mechanism includes first and second bristles of different hardness. One of the first and second bristles is located outside the roller, while the other is located inside the hollow cavity of the roller. The bristles located outside the roller clean the surface to be cleaned, while the unused bristles are located inside the roller. The structure is simple and makes full use of the roller's space, resulting in a miniaturized roller brush mechanism. Depending on the cleaning needs, the support moves on the roller to switch the positions of the first and second bristles on the roller to either outside the roller or inside the hollow cavity, thereby changing the type of bristles located outside the roller. This eliminates the need to replace the roller brush to meet different cleaning needs, saving time and simplifying operation.

[0094] In addition, as a variation, the support can switch between the two types of bristles through other movements. For example, there can be at least two supports, with the first bristle mounted on one support and the second bristle mounted on a second support. The extension and retraction of the supports controls whether the connected bristles are outside the roller or inside the hollow cavity. In short, one of the first and second bristles can be located outside the roller, and the other inside the hollow cavity. The drive mechanism can be a cylinder or a lead screw, etc., to achieve the extension and retraction movement.

[0095] Example 2

[0096] This embodiment provides a cleaning device, which can be a sweeper, floor scrubber, or other equipment for cleaning surfaces to be cleaned. The cleaning device includes a body and a roller brush mechanism mounted on the body, wherein the roller brush mechanism is the roller brush mechanism shown in Embodiment 1.

[0097] The machine body moves on the surface to be cleaned by the drive component, and the roller of the roller brush mechanism rotates under the drive end so that the first or second bristles located outside the roller can clean the surface to be cleaned.

[0098] When the brush bristles need to be replaced to suit the corresponding usage scenario, the end cap and the abutment are simultaneously removed, and the roller is detached from the drive end. At this time, the first end of the roller with the sliding member is exposed. The abutment connects the abutment and the sliding member through the exposed first end of the roller, driving the abutment to move towards the second end of the roller, causing the sliding member and the bracket to move, realizing the switching between the first and second brush bristles. Then, the roller is rotated 180 degrees to swap the two ends of the roller, and then the sliding member is connected to the drive end. The motor on the drive end is started to perform cleaning work. This operation is simple and requires no additional operation. Cleaning equipment with this roller brush mechanism has diverse functions and high cleaning efficiency. Alternatively, the roller and sliding member can be detached from the drive end, the roller can be rotated 180 degrees to swap the first and second ends of the roller, and then the abutment is used to push the sliding member to slide inside the roller. For example, in Figure 7 In the middle, the roller is disassembled along direction A, rotated 180 degrees, and the two ends of the roller are swapped. The abutment part is along direction B, pushing the sliding part to slide, which drives the bracket to slide until the second end of the sliding part is inserted and engaged with the drive end.

[0099] In addition, a magnetic component may be provided on the end cap, and a magnetic suction component may be provided on the main body to attract the magnetic component. Through the cooperation of the magnetic component and the magnetic suction component, the end cap can be fixed and stable on the main body.

[0100] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. Based on the embodiments of the present invention, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the scope of protection of the present invention.
