DETAILED DESCRIPTION

[0095] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0096] like Figure 1 As shown, an embodiment of the present disclosure provides a roller brush assembly 3, a cleaning robot 2 having the roller brush assembly 3, and a cleaning system having the cleaning robot 2. The cleaning system mainly includes the cleaning robot 2 and a base station 1 for the cleaning robot 2 to dock. The cleaning robot 2 includes the roller brush assembly 3 for cleaning the floor, and the base station 1 includes a cleaning assembly 4 that can remove entanglements on the roller brush assembly 3.

[0097] like Figure 13 As shown, the roller brush assembly 3 includes a roller brush body 31 and a working member 32 mounted on the roller brush body 31. The roller brush body 31 drives the working member 32 to rotate and sweep the surface to be cleaned (e.g., the floor). It should be noted that the roller brush body 31 can be configured as a cylindrical roller, a cylinder, or the like. The working member 32 includes any one or a combination of a rubber strip 321, a cloth strip, or bristles 322.

[0098] Furthermore, the roller brush assembly 3 includes at least one support structure, which is disposed at at least one end of the roller brush body 31. Support structures may be disposed at both ends of the roller brush body 31, or at one end of the roller brush body 31. The number of support structures disposed at one end of the roller brush body 31 may be one, two, or three, etc., and is not specifically limited here and may be configured as needed.

[0099] The support structure includes two support members 34 arranged axially along the roller brush body 31. The support members 34 extend from the ends of the roller brush body 31 to the middle of the roller brush body 31, that is, the support members 34 extend axially along the roller brush body 31. (In the following description, the first support member 341, the first guide portion 343, the blocking portion 332, the second support member 342, the second guide portion 344, the support structure, the first end surface 336, the mounting portion 335, the cover plate 333, and the connecting portion 334 are all components of the end cover 33.) The support members 34 radially protrude relative to the outer surface of the roller brush body 31. That is, in the radial direction of the roller brush body 31, the support members 34 are higher than the circumferential outer surface of the roller brush body 31, so that the winding material can be wound around and supported.

[0100] The two support members 34 of the support structure are respectively located on both sides of the end of the working member 32. The working member 32 and the support member 34 at least partially overlap in the axial direction of the roller brush body 31 to support the working member 32, prevent the working member 32 from tipping over, and avoid hair and other entanglements from being entangled on the roller brush body 31.

[0101] Since the two support members 34 of the support structure are located on both sides of the end of the working member 32, the working member 32 and the support members 34 have an overlapping portion in the axial direction of the roller brush body 31, that is, the working member 32 extends into the support structure, so the support structure formed between the two adjacent support members 34 can clamp the end of the working member 32. The entangled objects tend to gather at the end of the roller brush body 31. When the entangled objects gather more and more, they may exceed the bearing capacity of the working member 32 for the entangled objects. The entangled objects may overwhelm the working member 32 at the end of the roller brush body 31 and then entangle the roller brush body 31, so that when the cleaning component 4 of the base station 1 is used for cleaning later on the base station 1, the hooking member 41 ( Figure 7Therefore, the support structure clamps the working piece 32 in the middle to provide support for it, which can effectively prevent the entangled objects from pressing the working piece 32 down and entangled with the roller brush body 31, so that the working piece 32 can effectively support the entangled objects, and further enable the hooking member 41 to successfully hook the entangled objects. On the other hand, during the operation of the roller brush assembly 3, the working piece 32 rotates around the roller brush body 31 under the drive of the roller brush body 31 to clean the ground. Since the working piece 32 is clamped, the working piece 32 will not fall in the direction opposite to the rotation direction due to the resistance of the ground, which can improve the cleaning effect of the ground and extend the service life of the working piece 32. Secondly, the working piece 32 and the support piece 34 at least partially overlap in the axial direction, avoiding the existence of a gap between the support piece 34 and the working piece 32 in the axial direction of the roller brush body 31. Such a setting can ensure that the entangled objects guided from the end of the roller brush body 31 toward the middle of the roller brush body 31 will not enter the gap between the support piece 34 and the working piece 32.

[0102] It should be noted that the working piece 32 has two ends, namely a first end and a second end that are arranged opposite each other. The two support members 34 of the support structure can be located at the same end of the working piece 32, that is, the two support members 34 are located on both sides of the first end to support the first end to prevent the first end from collapsing under the action of the entanglement, or the two support members 34 are located on both sides of the second end to support the second end to prevent the second end from collapsing under the action of the entanglement. In other embodiments, the two support members 34 of the support structure can be located at both ends of the roller brush body 31, that is, one support member 34 is located on one side of the first end of the working piece 32, and the other support member 34 is located on the other side of the second end of the working piece 32. This support structure also has a certain supporting effect on the working piece 32. Furthermore, for a working piece 32, both its first and second ends are provided with support structures. By supporting both ends of the working piece 32 through the two support structures, the two ends of the working piece 32 can be effectively prevented from collapsing under the action of the entanglement, facilitating the subsequent cleaning of the entanglement.

[0103] The minimum distance between the working piece 32 and the support members 34 located on both sides of the working piece 23 is less than or equal to 0.5 mm. That is, the gap formed in the middle of the support structure can be slightly larger than, or roughly equal to, or slightly smaller than the thickness of the working piece 23 extending therein. It is understandable that there is a small gap between the working piece 23 and the support member 34, and the support member 34 can still play a supporting role for the working piece 23. When the working piece 23 tilts to a certain degree, it abuts against the support member 34, and the support member 34 prevents the working piece 23 from continuing to tilt. Because the support member 34 protrudes from the surface of the roller brush body 31, the support member 34 and the working piece 23 can effectively support the entanglement. When the gap between the working piece 23 and the support member 34 supporting it is too large, the support member 34 will not play a supporting role. Under the action of the entanglement, the end of the working piece 23 will still collapse. Therefore, the maximum gap between the working piece 23 and the support member 34 supporting it does not exceed 0.5 mm. Of course, the gap formed in the middle of the support structure is roughly equal to or slightly smaller than the thickness of the workpiece 32. The outer surface of the workpiece 32 is in contact with the surface of the support structure, so that the support structure not only supports the workpiece 32, but also tightly clamps the workpiece 32, further ensuring the stability of the positional relationship between the support structure and the workpiece 32, and effectively avoiding the workpiece 32 from escaping from the gap of the support structure under the action of excessive entanglements, causing the entanglements to enter the axial gap between the workpiece 32 and the support member 34, and also facilitating the insertion of the workpiece 32 with deformation function into the support structure.

[0104] The hardness of a complete workpiece 32 can be the same or different. For example, the hardness of the part of the workpiece 32 clamped by the support structure can be greater than the hardness of the rest of the workpiece 32. At least part of the workpiece 32 can be set as a hard part 323, and this hard part 323 is a hard cloth strip or a hard rubber strip, which is a component of the workpiece 32. When the overall hardness of the workpiece 32 is different, the two adjacent support members 34 form a support structure to clamp at least part of the hard part 323. The support member 34 forms a support structure for clamping the end of the workpiece 32. When the workpiece 32 has hard cloth strips or hard rubber strips at both ends along the axial direction of the roller brush body 31, the part of the workpiece 32 clamped by the support structure is a hard cloth strip or a hard rubber strip, which can effectively prevent the hard part 323 from tipping over and better prevent the entanglement from sliding off the support member 34.

[0105] In this embodiment, the support structure tightly clamps the workpiece 32. The workpiece 32 held by the support structure is configured as a strip of cloth or rubber. The support structure's clamping of the workpiece 32 can increase the hardness of the workpiece 32 (the rubber or cloth strip) to a certain extent, enabling the hardness of the workpiece 32 to intercept entangled objects that may slide toward the center of the roller brush body 31. If the workpiece 32 is a rubber strip, the hard portion 323 is not required; the hardness of the rubber strip itself can be sufficient for clamping.

[0106] The support member 34 includes a guide portion 340. The guide portion 340 decreases in height in the radial direction of the brush body 31, extending axially from the end of the brush body 31 toward the middle of the brush body 31. This guide guides the winding material wrapped around the support member 34 from the end of the brush body 31 toward the middle of the brush body 31. Furthermore, the height of the working member 32 in the radial direction of the brush body 31 is greater than the height of the guide portion 340 near the end of the working member 32. This allows the end of the working member 32 to serve as a barrier to prevent the winding material from excessively moving toward the middle of the brush body 31, thereby confining the winding material between the guide portion 340 and the working member 32. Specifically, the support member 34 is mounted on an end cap 33, which is removably mounted to at least one end of the brush body 31. Alternatively, the support member 34 can be directly connected to the outer surface of at least one end of the brush body 31.

[0107] It should be noted that, with respect to the setting of the guide portion 340, the height of the support member 34 changes as it extends in the axial direction. For example, the end of the support member 34 away from the middle of the roller brush body 31 has a larger height, and as it extends toward the middle of the roller brush body 31, the height of the support member 34 gradually decreases, and the reduced part forms the guide portion 340. Through this size improvement, when the support member 34 extends toward the middle of the roller brush body 31, the larger height portion of its top edge and the smaller height portion are transitionally connected by a smooth arc surface or inclined surface or a combination of an arc surface and an inclined surface, so that the wound material is gradually tightened on the support member 34 and is guided by the arc surface or inclined surface into between the guide portion 340 and the working member 32. In other embodiments, the guide portion 340 may also include at least a partial plane, that is, when the support member 34 extends toward the middle of the roller brush body 31, the portion with a larger height at the top edge is transitionally connected to the portion with a smaller height by a combination of an arc surface and a plane, or a combination of an inclined surface and a plane, or a combination of an arc surface, an inclined surface and a plane, at least to ensure that the height of the guide portion 340 does not rise when the support member 34 extends toward the middle of the roller brush body 31.

[0108] In the radial direction of the roller brush body 31, the height of the working piece 32 is greater than the height of the end of the guide portion 340 near the working piece 32. Specifically, the distance between the top of the working piece 32 and the outer surface of the roller brush body 31 is the height of the working piece 32, and the distance between the top of the smaller portion of the guide portion 340 and the outer surface of the roller brush body 31 is less than the height of the working piece 32. In addition, the support member 34 and the working piece 32 at least partially overlap along the axial direction of the roller brush body 31, forming a "√"-like structure between the support member 34 and the working piece 32 along the axial direction of the roller brush body 31, thereby confining entangled objects between the guide portion 340 and the working piece 32. Optionally, the height of the working piece 32 is greater than the height of the guide portion 340, so that the working piece 32 can serve as a barrier to prevent hair from entering the axial direction between the support member 34 and the working piece 32, and can also prevent the support member 34 from interfering with the ground during cleaning.

[0109] Furthermore, in the radial direction of the roller brush body 31, the height of other parts of the support member 34 is greater than the height of the guide portion 340. The height of the support member 34 refers to the radial extension of the support member 34. Making other parts of the support member 34 higher than the radial extension of the guide portion 340 is beneficial for guiding the windings, so that the windings are more concentrated on the guide portion 340 or between the guide portion 340 and the working member 32.

[0110] like Figure 1 、 Figure 7 and Figure 13 As shown, since the support member 34 is higher than the circumferential outer surface of the roller brush body 31, there is a radial hooking gap between the winding material wound on the support member 34 and the roller brush body 31, so as to allow the hooking member 41 described later to extend under the winding material to hook the winding material; the cleaning assembly 4 includes a hooking member 41 and a driving member (not shown) for driving the hooking member 41, such as a motor, a cylinder, etc., and the hooking member 41 is, for example, a strip member provided with hooks 411. At the same time, in order to more fully hook the winding material on the roller brush assembly 3, the length edge of the strip member is covered with hooks 411, and the hooking member 41 can be driven by the driving member to move axially and radially relative to the roller brush body 31, so that the hooking member 41 can be driven by the driving member by the driving member to extend into the hooking gap by moving axially and radially relative to the roller brush body 31, thereby realizing the hooking of the winding material between the guide portion 340 and the working member 32 at the axial ends of the roller brush body 31. Of course, the entangled object will also be wrapped around the middle of the roller brush body 31. The working part 32 arranged on the roller brush body 31 will generate a supporting force on the entangled object, so that the entangled object wrapped around the middle of the roller brush body 31 also has a radial hooking gap with the roller brush body 31, thereby enabling the hooking component 41 to hook the entangled object wrapped around the middle of the roller brush body 31.

[0111] In the above-mentioned cleaning system, when the cleaning robot 2 performs a cleaning operation, the roller brush assembly 3 rotates to cause the working piece 32 thereon to sweep the floor. As the roller brush assembly 3 rotates, tangled objects such as hair and lint on the floor will become entangled in the roller brush assembly 3. Due to the suction and collection of the tangled objects by the fan installed inside the cleaning robot 2, and based on the structure of the working piece 32 on the roller brush body 31, some of the tangled objects gradually move toward the axial ends of the roller brush body 31 and eventually move to the ends of the roller brush body 31. The roller brush assembly 3 is mounted on the cleaning robot 2 via the mounting portion 335. Due to the interference of the outer shell of the cleaning robot 2, the movement trajectory of the hooking member 41 is difficult to cover the entire end of the roller brush body 31, especially the end of the roller brush body 31 connected to the mounting portion 335. The hooking member 41 cannot reach it, and the tangled objects entangled in this end of the roller brush body 31 are difficult to be removed by the hooking member 41.

[0112] Since the end portion is provided with an axially extending and radially protruding support member 34, and since the radially protruding height of the support member 34 is less than the radially protruding height of the working member 32 relative to the roller brush body 31, that is, the working member 32 is higher than the support member 34, the winding material moving from the working member 32 to the end portion of the roller brush body 31 will fall on the support member 34 and be wound on the support member 34, and since the support member 34 is provided with a guide portion 340, the guide portion 340 will guide the winding material wound on the support member 34 in a direction away from the end portion of the roller brush body 31. Under the restriction of the working member 32, the winding material cannot escape from the guide portion 340 and fall on the roller brush body 31, so the winding material located on the support member 34 will eventually move between the guide portion 340 and the working member 32 and be wound at this position, so that the winding material is away from the end portion of the roller brush body 31 that the hooking member 41 cannot hook, and there is a hooking gap between the winding material and the roller brush body 31. Figure 1 and Figure 7As shown, when it is necessary to clean the entangled objects on the roller brush assembly 3, the cleaning robot 2 returns to the base station 1 and stays at the position where the roller brush assembly 3 and the cleaning assembly 4 correspond. Then, the driving component provided on the base station 1 is started to drive the hooking component 41 to approach the roller brush body 31, and move the hooking component 41 along the axial and radial directions of the roller brush body 31 and enter the hooking gap, so that the entangled objects enter the hooking space of the hooking component 41, and the hooking component 41 continues to move along the axial and radial directions of the roller brush body 31 to enable the hooking component 41 to hook the entangled objects on the support member 34. In other words, the hooking component 41 performs a circular motion driven by the driving component, and the movement trajectory of the hooking component 41 is circular (or elliptical), and the circular trajectory (or elliptical trajectory) covers the above-mentioned hooking gap. Furthermore, the hooking member 41 hooks the winding material to the setting position of the shearing component of the base station 1 to achieve the cutting of the winding material (or the hooking edge of the hook 411 can be processed into a blade so that the hook 411 directly cuts the winding material and the shearing component is omitted). The cut winding material fragments are sucked away by the cleaning robot 2 or other components of the base station 1, thereby clearing the winding material wrapped around the roller brush assembly 3. Through this structure, the winding material can be prevented from entering the bearing of the roller brush body 31, and the winding material can be cleared more easily and conveniently, effectively preventing hair accumulation and blocking of the roller brush assembly 3, and improving the working performance of the cleaning system. In other embodiments, the cleaning assembly 4 may also not be provided with a driving member, and the roller brush assembly 3 is driven to move relative to the hooking member 41 to achieve the hooking of the winding material from the roller brush assembly 3 by the hooking member 41.

[0113] In one embodiment, if Figure 2 and Figure 3As shown, one or more support members 34 can be set on the roller brush body 31. Different support members 34 can have different structures. For the sake of distinction, one of the structures of the support member 34 is defined as a first support member 341. In the axial direction, the first support member 341 extends from the end of the roller brush body 31 to the middle of the roller brush body 31, and includes a first guide portion 343 and a blocking portion 332. Among them, along the extension direction of the first support member 341, the radial height of the first guide portion 343 on the roller brush body 31 gradually decreases, that is, from the end of the roller brush body 31 toward the middle of the roller brush body 31, the radial height of the first guide portion 343 on the roller brush body 31 decreases, so that it can guide the winding wrapped on the first support member 341, so that the winding wrapped on the first support member 341 moves from the end of the roller brush body 31 toward the middle of the roller brush body 31 and is guided, and the blocking portion 332 is located at the end of the first guide portion 343 away from the end, that is, the blocking portion 332 is closer to the middle of the roller brush body 31 relative to the first guide portion 343, and the radial height of the blocking portion 332 on the roller brush body 31 is greater than the radial height of the end of the first guide portion 343 close to the blocking portion 332 on the roller brush body 31. The blocking portion 332 blocks the guided windings, preventing them from excessively moving toward the center of the roller brush body 31, thereby confining the windings between the first guide portion 343 and the blocking portion 332. Specifically, the support member 34 is mounted on the end cap 33, which is detachably mounted on at least one end of the roller brush body 31. Alternatively, the support member 34 may be directly connected to the outer surface of at least one end of the roller brush body 31.

[0114] As described above, since the first support member 341 is higher than the circumferential outer surface of the roller brush body 31, there is a radial hooking gap between the winding material wound on the first support member 341 and the roller brush body 31, so as to allow the hooking member 41 to extend under the winding material to hook the winding material. Since the first support member 341 is provided with a first guide portion 343, the first guide portion 343 will guide the winding material wound on the first support member 341 in a direction away from the end of the roller brush body 31. Under the restriction of the blocking portion 332, the winding material cannot escape from the first guide portion 343 and fall onto the roller brush body 31. Therefore, the winding material located on the support member 34 will eventually move between the first guide portion 343 and the blocking portion 332 and be wound at this position, so that the winding material is away from the end portion of the roller brush body 31 that the hooking member 41 cannot hook, and there is a hooking gap between the winding material and the roller brush body 31. Figure 1 and Figure 7As shown, when it is necessary to clean the entangled objects on the roller brush assembly 3, the cleaning robot 2 returns to the base station 1 and stays at the position where the roller brush assembly 3 and the cleaning assembly 4 correspond. Then, the driving component provided on the base station 1 is activated to drive the hooking component 41 to approach the roller brush body 31, and move the hooking component 41 along the axial and radial directions of the roller brush body 31 and enter the hooking gap, so that the entangled objects enter the hook space of the hooking component 41, and the hooking component 41 continues to move along the axial and radial directions of the roller brush body 31 to enable the hooking component 41 to hook the entangled objects on the support member 34. Through this structure, the entangled objects can be prevented from entering the bearing of the roller brush body 31, and the entangled objects can be removed more easily and conveniently, effectively preventing hair accumulation and blocking of the roller brush assembly 3, and improving the working performance of the cleaning system.

[0115] like Figure 3-Figure 6 As shown, in the radial direction of the roller brush body 31, the height of other parts of the first support member 341 is greater than the height of the first guide portion 343. The height of the first support member 341 refers to the radial extension of the first support member 341. Making other parts of the first support member 341 higher than the radial extension of the first guide portion 343 is beneficial for guiding the windings, so that the windings are more concentrated on the first guide portion 343 or between the first guide portion 343 and the blocking portion 332. With respect to the first guide portion 343, the height of the first support member 341 varies as it extends axially. For example, the end of the first support member 341 away from the middle of the roller brush body 31 has a greater height. As it extends toward the middle of the roller brush body 31, the height of the first support member 341 gradually decreases, forming the first guide portion 343. This improved dimension allows the first support member 341 to smoothly transition from a higher height portion to a lower height portion of its top edge as it extends toward the middle of the roller brush body 31. This allows the wound material to be gradually tightened around the first support member 341, guided by the curved or inclined surface, and enter between the first guide portion 343 and the blocking portion 332. Furthermore, to minimize the risk of the wound material escaping from the end of the first support member 341 near the working member 32, the aforementioned blocking portion 332 is provided at the lower height portion of the first guide portion 343 to block the wound material within the receiving portion 341.

[0116] Furthermore, the edge of the first support member 341 extends away from the roller brush body 31 to form a blocking portion 332. That is, in the axial direction of the roller brush body 31, the blocking portion 332 is formed at a location with a smaller height of the first guide portion 343 and extends away from the roller brush body 31 at that location. Furthermore, in the radial direction of the roller brush body 31, the height of the blocking portion 332 is greater than the height of the first guide portion 343 at one end near the blocking portion 332 and less than the height of the working member 32. By forming the blocking portion 332 on the edge of the first support member 341 near the middle of the roller brush body 31, the blocking portion 332 can be integrally formed with the first guide portion 343, becoming an integral part of the first support member 341 and maintaining the same structure as the entire support member 34. For example, if the support member 34 is a plate-shaped rib provided on the end cap, the blocking portion 332 is also plate-shaped. Since the blocking portion 332 is taller than the first guide portion 343, the blocking portion 332 and the first guide portion 343 cooperate to form a barb on the support member 34. Making the blocking portion 332 taller than the first guide portion 343 confines entangled material between the first guide portion 343 and the blocking portion 332, preventing it from falling off the support member 34 and becoming entangled in the roller brush body 31, making it difficult to clean. Making the blocking portion 332 shorter than the working member 32 prevents the support member 34 from interfering with the ground and causing it to hit the ground.

[0117] In a further embodiment, the working piece 32 and the blocking portion 332 are connected or have overlapping parts in the axial direction of the roller brush body 31, that is, there is no gap between the blocking portion 332 and the working piece 32 in the circumferential direction, so that the entangled material can be prevented from entering the gap between the support member 34 and the working piece 32, and the entangled material is prevented from being directly wound around the roller brush body 31 and exceeding the hooking range of the hooking member 41 (specifically, exceeding the hooking range of the hooking member 41 in the radial direction), making the entangled material easier to clean.

[0118] like Figure 3 and Figure 6 As shown, at least two first support members 341 are provided on the circumference of the roller brush body 31, for example Figure 3 There are six as shown, or Figure 6 As shown, three are provided to achieve multi-point support for the entangled object in the circumferential direction of the roller brush body 31, further facilitating the cleaning of the entangled object. When the hooking member 41 is hooked at multiple phases relative to the roller brush assembly 3, the entangled object is always within the hooking range of the hooking member 41. The multiple phases of the roller brush assembly 3 refer to the roller brush assembly 3 rotating and stopping at multiple angles relative to the cleaning robot 2.

[0119] In addition to the above, the support member 34 also includes a second support member 342 (which is the support member 34 described above) of another structure. The second support member 342 is arranged on the roller brush body 31 in the same manner as the first support member 341 is arranged relative to the roller brush body 31. The second support member 342 extends from the end of the roller brush body 31 toward the middle of the roller brush body 31 and radially protrudes relative to the outer surface of the roller brush body 31. The second support member 342 includes a second guide portion 344. The height of the second guide portion 344 in the radial direction of the roller brush body 31 decreases along the extension direction of the second support member 342, so as to guide the winding material wrapped around the second support member 342 from the end of the roller brush body 31 toward the middle of the roller brush body 31. The first support member 341 and the second support member 342 are distributed along the circumference of the roller brush body 31. That is, the second support member 342 extends axially along the roller brush body 31 and protrudes radially relative to the outer surface of the roller brush body 31. The second support member 342 includes a second guide portion 344. The second guide portion 344 decreases in height radially along the roller brush body 31 in the axial direction extending from the end of the roller brush body 31 toward the middle of the roller brush body 31, thereby guiding the material wrapped around the second support member 342 from the end of the roller brush body 31 toward the middle of the roller brush body 31. This arrangement also allows the first support member 341 and the second support member 342 to be distributed along the circumference of the roller brush body 31. In other words, the second support member 342 differs from the first support member 341 in that the second support member 342 no longer includes the blocking portion 332.

[0120] When the hooking member 41 hooks the entangled object on the roller brush assembly 3, it will move axially and radially relative to the roller brush assembly 3, and there is a certain probability that it will collide with the blocking portion 332, forming interference with the blocking portion 332. The first support member 341 and the second support member 342 are simultaneously provided on the roller brush body 31, which can reduce the probability of interference between the hooking member 41 and the blocking portion 332 while effectively supporting the entangled object.

[0121] Specifically, when the blocking portion 332 is provided, Figure 3 As shown, the blocking portion 332 does not need to be provided on each support member 34 to maintain a good blocking effect on the entangled objects, so the blocking portion 332 can be provided at intervals in the middle of all the support members 34, that is, the first support members 341 and the second support members 342 are alternately provided in the circumferential direction of the roller brush body 31, so that the blocking portion 332 is alternately provided in the circumferential direction of the roller brush body 31. In other embodiments, two first support members 341 are also provided at intervals, and the remaining are provided as second support members 342. The number and position of the first support members 341 and the second support members 342 are not specifically limited here, and can be provided according to actual needs. Figure 13In the illustrated embodiment, the second support members 342 are provided in the circumferential direction of the roller brush body 31 , which can effectively block the entangled objects and facilitate the hooking member 41 to hook the entangled objects.

[0122] A support structure is formed between two adjacent support members 34 to clamp at least a portion of the workpiece 32, preventing it from falling and preventing entanglements such as hair from becoming entangled in the brush body 31. Because the workpiece 32 and support members 34 overlap axially with respect to the brush body 31, meaning the workpiece 32 extends into the support structure, the support structure formed between the two adjacent support members 34 can clamp the ends of the workpiece 32. As can be seen above, entanglements tend to accumulate at the ends of the brush body 31. As the accumulation of entanglements increases, it may exceed the load-bearing capacity of the workpiece 32. The entanglements may overwhelm the workpiece 32 at the ends of the brush body 31, further entangling the brush body 31 and making it difficult for the hooking member 41 to reach it. Therefore, the support structure clamps the workpiece 32 and provides support for it, effectively preventing the entanglements from overwhelm the workpiece 32 and entanglement in the brush body 31. This allows the workpiece 32 to effectively support the entanglements, further enabling the hooking member 41 to successfully reel in the entanglements. On the other hand, during the operation of the roller brush assembly 3, the working piece 32 rotates around the roller brush body 31 driven by the roller brush body 31 to clean the ground. Since the working piece 32 is clamped, the working piece 32 will not fall in the direction opposite to the rotation direction due to the resistance of the ground, which can improve the cleaning effect of the ground and extend the service life of the working piece 32.

[0123] Furthermore, since the support member 34 includes a first support member 341 and a second support member 342, the support structure can be formed by cooperating with different types of support members 34. For example, the support structure includes a first support structure, and the two support members 34 constituting this first support structure are respectively a first support member 341 provided with a blocking portion 332 and a second support member 342 not provided with a blocking portion 332. The two together realize the clamping of the same working member 32. Such a setting can not only enable the blocking portion 332 to prevent the winding material from sliding directly into the gap between the support member 34 and the working member 32 through the guidance of the first guide portion 343 and the second guide portion 344, but also reduce the probability of interference between the blocking portion 332 and the hooking member 41 when the hooking member 41 hooks the winding material on the roller brush assembly 3, and also enable the first support structure to effectively clamp and effectively support the working member 32 at the end of the roller brush body 31. Furthermore, since the blocking portion 332 has a relatively large height, the first support member 341 provided with the blocking portion 332 can be located behind the second support member 342 in the rotation direction of the roller brush body 31 in the two support members 34 constituting the first support structure. By so configuring, the first support member 341 having a larger area of the blocking portion 332 can also play a major blocking role on the working member 32, thereby preventing the working member 32 from tilting excessively due to resistance when cleaning the floor, thereby improving the working effect of the working member 32.

[0124] The support structure may also include a second support structure. In this second support structure, both support members 34 that comprise the second support structure are second support members 342 that are not provided with blocking portions 332. This also enables clamping and preventing the workpiece 32 from tipping over. However, in the present disclosure, the support structure for clamping the workpiece 32 includes more than just the second support structure. In other words, the support structure for clamping the workpiece 32 includes at least the first support structure. Specifically, both support members 34 may be the first support structure, or a combination of the first and second support structures.

[0125] To further optimize the effectiveness of the hooking member 41 in hooking entangled objects on the roller brush assembly 3, in one embodiment, a first support structure and two second support structures are provided circumferentially around the roller brush body 31. The hooking position of the hooking member 41 is closer to the second support structure than to the first support structure. It will be appreciated that when the hooking member 41 is hooking entangled objects on the roller brush assembly 3, the axes of the hooking member 41 and the roller brush body 31 are substantially parallel. During movement, the axial displacement component of the hooking member 41 is also parallel to the axis of the roller brush body 3132. The closer proximity of the hooking member 41 to the second support structure during movement effectively reduces the probability of interference between the hooking member 41 and the blocking portion 332. Specifically, the hooking position of the hooking member 41 is located in the middle of the second support structure, that is, between the first support member 341 and the second support member 342 (hereinafter referred to as the clamping gap, since the hooking position of the hooking member 41 in this embodiment is located in the clamping gap, the clamping gap is referred to as the hooking gap). In one embodiment, the roller brush body 31 has at least two first support structures and at least two second support structures evenly distributed along the circumference. For example, the roller brush body 31 has three first support structures and three second support structures evenly distributed along the circumference.

[0126] Furthermore, the working piece 32 can specifically be one or more combinations of rubber strips 321, cloth strips, and bristles 322. The working piece 32 clamped by the second supporting structure is a rubber strip 321 or a cloth strip (a component that is continuous and unbroken in the axial direction at the position in contact with the ground), and the working piece 32 clamped by the first supporting structure is set as bristles 322. Regarding the selection of the hooking position, after repeated tests, it was found that the windings wrapped around the bristles are more likely to be lifted up when the hooking member 41 moves than the windings wrapped around the rubber strips or cloth strips, and move toward the mounting portion 335 of the roller brush assembly 3, and be wrapped around the mounting portion 335, thereby causing the roller brush assembly 3 to be unable to rotate. Therefore, in this embodiment, the hooking position is set near the second supporting structure where the rubber strips or cloth strips are installed.

[0127] Based on the consideration of optimizing the performance of the roller brush assembly 3, the working piece 32 clamped by the second supporting structure is selected as a rubber strip 321 or a cloth strip. Because the clamping area and blocking area of the second supporting structure are smaller than those of the first supporting structure, and the bristles 322 are softer, they are more likely to fall over when cleaning the floor. Therefore, in order to more fully clamp and block the bristles 322, it is preferred to use the first supporting structure with a larger clamping area and blocking area to cooperate with the bristles 322, and the remaining rubber strips 321 or cloth strips are clamped by the second supporting structure.

[0128] In other embodiments, the support structure can also be a third support structure, and the two support members 34 that constitute the third support structure are both first support members 341 provided with a blocking portion 332. In this way, the working member 32 can be fully clamped and blocked in both the front and rear directions, which can make the working performance of the roller brush assembly 3 more prominent.

[0129] In another embodiment, the hooking position of the hooking member 41 can be set at a position different from that of the above embodiment. At the end of the roller brush body 31, in addition to the clamping gap formed by the support structure in the circumferential direction and capable of accommodating the workpiece 32, the aforementioned hooking gap is also provided. In a specific structure, at least two support structures are provided in the circumferential direction of the roller brush body 31. Therefore, there are two types of gaps formed in the circumferential direction of the roller brush body 31: one is the gap between two support members 34 of the same support structure, i.e., the clamping gap; the other is the gap between two adjacent different support structures. This gap is the hooking gap that allows the hooking member 41 to enter. In order to further optimize the structure, the distance between the two support members 34 forming the same support structure (which can also be understood as the circumferential dimension of the clamping gap) is smaller than the minimum distance between two adjacent support structures (which can also be understood as the circumferential dimension of the hooking gap). In this way, while achieving normal clamping of the workpiece 32, it can also be ensured that the hooking gap has sufficient size to allow the hooking member 41 to enter and exit, providing further convenience for cleaning entanglements.

[0130] Similarly, in the embodiment where all the supporting members 34 are second supporting members 342 , the hooking positions of the hooking members 41 can be set in the manner described above, which will not be described in detail here.

[0131] In addition, an insertion groove 331 is formed between the support structures arranged adjacent to each other in the circumferential direction. The insertion groove 331 allows the hooking member 41 to enter the hooking gap. That is to say, by forming the insertion groove 331, the hooking member 41 can easily enter the hooking gap. Specifically, the hooking gap is the space in the groove of the insertion groove 331, and the height of the hooking gap (that is, the radial dimension) is the depth of the insertion groove 331. At the same time, the maximum height of the hooking gap (the maximum height of the hooking gap refers to the maximum height relative to the roller brush body 31) is lower than the hooking member 41 when it is at the maximum radial displacement, so that the hook 411 can enter the hooking gap or the insertion groove 331, and can move in the hooking gap to achieve the hooking of the entangled object. Moreover, in one embodiment, the hooking position of the hooking member 41 for hooking the winding object is on the side of the hooking gap close to the second supporting structure. The reason for this arrangement is that, on the one hand, the second supporting structure is not provided with a blocking portion 332, so the interference with the hooking member 41 can be reduced. On the other hand, since the second supporting structure clamps the rubber strip 321 or the cloth strip, it has better support relative to the bristles 322. If the hooking member 41 hooks the winding object near the bristles 322, it is easy to cause the displacement of the winding object and the hooking effect is poor. However, the winding object near the rubber strip 321 or the cloth strip will not encounter this problem. Therefore, the hooking position of the hooking mechanism 41 for hooking the winding object is on the side of the hooking gap close to the second supporting structure.

[0132] like Figure 3 As shown, when forming the blocking portion 332, the edge of the first support member 341 is extended in the direction away from the roller brush body 31 to form the blocking portion 332, that is, the blocking portion 332 is formed at the edge of the extension of the first support member 341, and, in the radial direction of the roller brush body 31, the height of the blocking portion 332 is greater than the height of the first guide portion 343 and less than the height of the working member 32, that is, the blocking portion 332 is formed by radially extending at one end of the first guide portion 343 close to the roller brush body 31 in the direction away from the roller brush body 31.

[0133] Between the first support member 341 and the second support member 342, which have different structures, in the axial direction of the roller brush body 31, the length of the first support member 341 provided with the blocking portion 332 is defined as a first length L1, and the length of the second support member 342 not provided with the blocking portion 332 is defined as a second length L2. Optionally, L1 ≥ L2, that is, the length of the support member 34 provided with the blocking portion 332 is longer, to prevent the blocking portion 332 from partially failing and failing to intercept entangled objects on the second guide portion 344. It is understandable that if the length of the second support member 342 is greater than the length of the first support member 341, entangled objects on the second guide portion 344 that exceed the length range of the first support member 341 will slide off the second guide portion 344 without being blocked by the blocking portion 332, and then entangled on the roller brush body 31, exceeding the hooking range of the hooking member 41. Furthermore, the working piece 32 and the blocking portion 332 overlap or connect in the axial direction of the roller brush body 31 to prevent the entangled material from entering the gap between the support member 34 and the working piece 32, exceeding the hooking range of the hooking member 41 and making it difficult to hook. On the other hand, the support member 34 provided with the blocking portion 332 has a larger overlapping length or contact area with the working piece 32, so that it can better cooperate with the working piece 32. Among them, since the blocking portion 332 is located at one end of the first support member 341 close to the middle of the roller brush body 31, the length of the first support member 341 is increased, which actually brings the blocking portion 332 closer to the working piece 32, thereby better clamping and blocking the working piece 32, and also enables the entangled material to be more conveniently moved between the first guide portion 343 and the blocking portion 332.

[0134] like Figure 5 As shown, in order to further optimize the cooperation between the blocking portion 332 and the working piece 32, in the axial direction of the roller brush body 31, the end face of the blocking portion 332 at one end away from the middle part of the roller brush body 31 is defined as the first end face 336, that is, the end face of the blocking portion 332 facing the first guide portion 343 is the first end face 336, and at both ends of the working piece 32 in the axial direction of the roller brush body 31, the distance between the end of the working piece 32 close to the first end face 336 and the first end face 336 is less than or equal to 1 mm. By such an arrangement, the difference between the axial length of the clamped portion of the working piece 32 (or the portion extending into the clamping gap) and the axial length of the blocking portion 332 is no more than 1 mm, so that almost the entire blocking portion 332 can be used to clamp the working piece 32. This structure can improve the clamping effect of the working piece 32, and can also make the end of the working piece 32 closer to the portion between the first guide portion 343 and the blocking portion 332 for accommodating the winding material, thereby better realizing the collection of the winding material.

[0135] like Figure 2 、 Figure 3 and Figure 6 As shown, the roller brush assembly 3 further includes a mounting portion 335 connected to the roller brush body 31 and used to mount the roller brush assembly 3 on the cleaning robot 2. A cover plate 333 is provided between the mounting portion 335 and the support member 34. In the radial direction of the roller brush body 31, the height of the cover plate 333 is greater than the height of the first guide portion 343 and the second guide portion 344. The function of the cover plate 333 is to prevent entangled objects from moving toward the mounting portion 335 of the roller brush assembly 3. Entangled objects on the mounting portion 335 hinder the rotation of the roller brush assembly 3.

[0136] In this embodiment, a mounting portion 335 is provided on the end cover 33. The end cover 33 is detachably mounted on both ends or one end of the roller brush body 31 and is used to mount the entire roller brush assembly 3 on the cleaning robot 2. A cover plate 333 is provided between the mounting portion 335 and the support member 34. In other words, the mounting portion 335 is connected to the support member 34 through the cover plate 333. Furthermore, a connecting portion 334 for connecting to the support member 34 is also provided on the cover plate 333. This connecting portion 334 is an annular structure arranged around the axis of the roller brush body 31. The connecting portion 334 is separated into a plurality of extending grooves 331 by a plurality of circumferentially arranged support members 34, so that the hooking member 41 can approach the winding object (i.e., move to the supporting plane of the winding object) through the extending groove 331 and hook the winding object. When the support member 34 is arranged on the mounting portion 335 and the connecting portion 334, the end of the support member 34 away from the working member 32 is connected to the cover plate 333 (the cover plate 333, the connecting portion 334 and the support member 34 and other structures can be integrally connected by injection molding), and the two adjacent support structures and the connecting portion 334 form a plurality of insertion grooves 331. Each insertion groove 331 is formed by a part of the connecting portion 334 and two adjacent support members 34. The volume of the insertion groove 331 is large, so that the hook 411 of the hooking member 41 can be inserted into it and move therein to complete the hooking of the entangled object.

[0137] Moreover, in the radial direction of the roller brush body 31, the height of the cover plate 333 is greater than the height of the connecting portion 334 and the first guide portion 343, so that the cover plate 333 forms a barrier to the entangled object in the axial direction of the roller brush body 31, preventing the entangled object from moving excessively on the roller brush body 31 and falling off the end of the roller brush body 31 and being entangled in the mounting portion 335.

[0138] In the above structure, in order to further optimize the working performance of the roller brush assembly 3 and make the roller brush assembly 3 better in collecting and removing entanglements, the size relationship between the cover plate 333 and other components is also defined, specifically:

[0139] like Figures 2 to 5As shown, after the roller brush assembly 3 is assembled, the distance between the end face of the working piece 32 and the surface of the cover plate 333 is defined as L3, the distance between the first end face 336 of the blocking portion 332 and the surface of the cover plate 333 is L4, the distance between the end of the second support member 342 (this end is the end close to the working piece 32, that is, the end of the support member 34 away from the cover plate 333) and the surface of the cover plate 333 is L5 (that is, L2 mentioned above), and the height difference between the maximum radius of the cover plate 333 and the radial highest point of the first guide portion 343 or the second guide portion 344 is L7, then L3, L4, L5 and L7 meet the following conditions:

[0140] L5>L4

[0141] L5>L3

[0142] |L4-L3|≤1mm

[0143] L7≥1mm

[0144] Among them, by making L5>L4, it is possible to ensure that the blocking part 332 can block the entanglement and prevent the entanglement from moving back to the working piece 32 again; by making L5>L3, it is possible to ensure that the working piece 32 and the blocking part 332 overlap in the axial direction of the roller brush body 31, so that there is no axial gap between the working piece 32 and the blocking part 332, and the entanglement cannot enter the gap between the support part 34 and the working piece 32; by making |L4-L3|≤1mm, it is possible to ensure that the entanglement is confined between the first guide part 343 and the blocking part 332; by making L7≥1mm, it is possible to ensure that the entanglement will not pass over the cover plate 333 and be entangled on the mounting part 335 or the shaft that drives the roller brush assembly 3 to rotate.

[0145] In other embodiments, the support member 34 of the roller brush assembly 3 is no longer divided into the first support member 341 and the second support member 342, and the support member 34 has a single shape. Figure 13 In this embodiment, the roller brush assembly 3 also has a roller brush body 31, and a working piece 32 is provided on the roller brush body 31. The difference from the above embodiment is that the blocking portion 332 is no longer formed on the above-mentioned first support member 341, but is formed by part of the working piece 32.

[0146] Specifically, the support member 34 is arranged at the end of at least one side of the roller brush body 31, and the support member 34 extends from the end of the roller brush body 31 to the middle of the roller brush body 31, and radially protrudes relative to the outer surface of the roller brush body 31. In the axial direction extending from the end of the roller brush body 31 to the middle of the roller brush body 31, the height of the support member 34 in the radial direction of the roller brush body 31 is reduced to guide the winding wrapped on the support member 34 from the end of the roller brush body 31 toward the middle of the roller brush body 31; the blocking portion 332 is provided as a part of the working member 32 that overlaps or connects with the support member 34 in the axial direction of the roller brush body 31, and the blocking portion 332 is configured to limit the winding between the support member 34 and the blocking portion 332.

[0147] In other words, the blocking portion 332 may no longer be formed on the first support member 341 (i.e., no longer integrally formed with the first guide member 343), but may be formed in another manner. For example, the blocking portion 332 may be formed at the end of the working member 32. In the axial direction of the roller brush body 31, the working member 32 overlaps or contacts the support member 34, thereby preventing a gap between the support member 34 and the working member 32 in the axial direction of the roller brush body 31. This arrangement ensures that entangled objects guided from the end of the roller brush body 31 toward the middle of the roller brush body 31 will not enter the gap between the support member 34 and the working member 32. Because the height of the working member 32 is greater than that of the support member 34, the end of the working member 32 can directly serve as the blocking portion 332. In other words, one or more of the bristles 322, cloth strips, or rubber strips 321 of the working member 32 can be used to block entangled objects.

[0148] The hardness of a complete working piece 32 can be the same or different. For example, the hardness of the blocking portion 332 can be made greater than the hardness of the rest of the working piece 32. At least a portion of the working piece 32 can be set as a hard portion 323, and the hard portion 323 forms a blocking portion 332. The blocking portion 332 is a hard portion arranged at the axial end of the working piece 32. This hard portion 323 is a hard cloth strip or a hard rubber strip, and the hard cloth strip or the hard rubber strip is a component of the working piece 32. In this embodiment, the first support member 341 has a structure similar to that of the second support member 342 (hereinafter referred to as the support member 34. In this embodiment, the structure of the support member 34 is similar to that of the second support member 342 above, and also has a guide portion, which guides the winding from the end of the roller brush body 31 to the middle of the roller brush body 31) and the hard portion on the working piece 32.

[0149] Furthermore, at least two support members 34 are provided along the circumference of the roller brush body 31. A support structure is formed between two adjacent support members 34 to clamp at least a portion of the working piece 32 and prevent the working piece 32 from falling over. The blocking portion 332 clamped by the support structure is configured as a cloth strip or a rubber strip. The support structure clamps the working piece 32 to a certain extent, which can improve the hardness of the working piece 32 (rubber strip or cloth strip), so that the hardness of the working piece 32 can intercept the entanglement sliding toward the middle of the roller brush body 31. It can be understood that the gap formed in the middle of the support structure is roughly equal to or slightly smaller than the thickness of the working piece 32, and the outer surface of the working piece 32 is in contact with the surface of the support structure, so that the clamping effect of the support structure is better, and it is also convenient for the working piece 32 with a deformation function to be inserted into the support structure.

[0150] When the overall hardness of the working member 32 is different, two adjacent support members 34 form a support structure that clamps at least a portion of the hard portion 323. The support members 34 form a support structure that clamps the ends of the working member 32. If the working member 32 has hard cloth strips or hard rubber strips at both ends along the axial direction of the roller brush body 31, the portion of the working member 32 clamped by the support structure is the hard cloth strips or hard rubber strips. This effectively prevents the hard portion 323 from tipping over and better prevents the wrapped object from sliding off the support members 34.

[0151] like Figure 2 As shown, the roller brush assembly 3 also includes a mounting portion 335, which is connected to the roller brush body 31 and is used to mount the roller brush assembly 3 on the cleaning robot 2. A cover plate is provided between the mounting portion 335 and the support member 34. In the radial direction of the roller brush body 31, the height of the cover plate is greater than the height of the support member 34. The support member 34 and / or the cover plate are configured to be deformable when subjected to external force. For example, the support member 34 and the cover plate can be separately or integrally formed as a rubber or soft rubber structure. When the roller brush assembly 3 is applied to the cleaning robot 2, the support member 34 and the cover plate formed of rubber or soft rubber can reduce damage to obstacles on the ground (such as wires, slippers, door sills) when they collide with obstacles on the ground.

[0152] Similarly, in this embodiment, the working member 32 is higher than the supporting member 34 in the radial direction of the roller brush body 31. This prevents the supporting member 34 from being lower than the working member 32 and interfering with the ground when the roller brush assembly 3 is installed on the cleaning robot 2 for operation.

[0153] In one embodiment, the support member 34 may be arranged in another form. For example, the working member 32 includes a rubber strip or a cloth strip. The rubber strip 321 is arranged on the roller brush body 31 and extends radially outward of the roller brush body 31. In the axial direction extending from the two ends of the roller brush body 31 to the middle part of the roller brush body 31, the height of the rubber strip 321 or the cloth strip at the two ends of the roller brush body 31 in the radial direction of the roller brush body 31 is reduced to form a first guide portion 343 of the first support member 341. The blocking portion 332 is arranged as a partial rubber strip or a partial cloth strip connected to the rubber strip at the lowest point of the first guide portion 343. By such an arrangement, at least one end of the rubber strip 321 on the roller brush assembly 3 for cleaning the floor is set to a structure with a low middle and high two ends, so that the rubber strip 321 can directly become a support member 34 that guides the winding material from the end of the roller brush body 31 toward the middle of the roller brush body 31 and supports the winding material, without providing a special component on the roller brush body 31 for winding the winding material, thereby simplifying the structure of the roller brush assembly 3 and improving the performance of the roller brush assembly 3.

[0154] like Figures 9 to 11 As shown, the present disclosure also provides a roller brush assembly 3, which can also be used with the cleaning robot 2 and adapted to the base station, and the cleaning assembly 4 on the base station is used to clean the entangled objects on the roller brush assembly 3. The roller brush assembly 3 has a roller brush body 31 and a working piece 32 on the roller brush body 31, which is substantially the same as the above-mentioned embodiment and will not be described in detail here. In this embodiment, the roller brush assembly 3 has a cover plate 333 (i.e., the cover plate 333 mentioned above. In this embodiment, the cover plate 333 is provided on the end cover. In other embodiments, the cover plate 333 can also be provided independently, for example, directly provided on the roller brush body 31). The cover plate 333 can be provided as an integrated structure continuously distributed in the circumferential direction of the roller brush body 31, that is, the cover plate 333 is a circular plate. However, in this embodiment, the cover plate 333 is configured as another structure, and is configured as a fan-shaped cover plate 333. Multiple fan-shaped cover plates 333 are evenly spaced around the circumference of the roller brush body 31. The support portion 345 is connected to the cover plate 333. The support portion 345 extends from the end of the roller brush body 31 to the middle of the roller brush body 31 and protrudes radially relative to the outer surface of the roller brush body 31. The support portion 345 props up the winding material wrapped around the end of the roller brush body 31, away from the outer surface of the roller brush body 31, forming a radial hooking gap for the hooking member 41 to penetrate and hook the winding material. In this embodiment, a structure (i.e., the support portion 345) for supporting hair is also provided at the end of the roller brush body 31. The support portion 345 can be arranged parallel to the axis of the roller brush body 31, and the radial protrusion height of each axially distributed portion of the support portion 345 relative to the roller brush body 31 is consistent.

[0155] Furthermore, each cover plate 333 is connected to a support portion 345. Furthermore, two adjacent support portions 345 form a support structure, and the area between the adjacent support structures is the spacing area between the two adjacent fan-shaped cover plates 333, that is, the two adjacent fan-shaped cover plates 333 have a gap here, forming a through groove. By setting it in this way, the axial movement range of the hooking member 41 in the through groove can be made larger, and the hooking member 41 will not be blocked by the cover plate 333 when hooking the winding material, so that the winding material can be cleaned more fully. The through groove enables the hooking structure to pass over the cover plate 333 in the axial direction of the roller brush body 31, avoiding the cover plate 333 interfering with the movement of the hooking member 41, solving the problem that the travel range of the hooking member 41 is limited by the cover plate 333, thereby increasing the travel range of the hooking member 41, and further enabling the hooking member 41 to hook the winding material near the cover plate 333. Therefore, in this embodiment, a structure for supporting hairs (i.e., a support portion 345) is further provided at the end of the roller brush body 31. The support portion 345 can be provided parallel to the axis of the roller brush body 31, and the axially distributed parts of the support portion 345 have the same radial protrusion height relative to the roller brush body 31. The difference from the above-mentioned support member 34 is that the support portion 345 does not have a guide portion for guiding the winding away from the end of the roller brush body 31, see Figure 11 or Figure 12 Of course, in order to better realize the hooking function of the hooking member 41, the support portion 345 can also be set as the support member 34 mentioned above.

[0156] On this basis, in order to further optimize the structure, such as Figure 11 As shown, a filler 337 can be provided in the gap (i.e., the through-slot) between two adjacent sector-shaped cover plates 333. The filler 337 can be made of, for example, rubber, specifically, a rubber sheet. The shape of the filler 337 matches the shape of the gap between the two adjacent sector-shaped cover plates 333, so that the filler 337 can better fill the gap. Furthermore, to avoid interference with the axial movement of the hooking member 41, a radially extending escape groove 338 is provided on the filler 337. During axial movement, the hooking member 41 can enter this escape groove 338 to ensure a sufficiently large axial travel, thereby ensuring a good removal effect of the hooking member 41. By adding this filler 337, the gap between the two adjacent sector-shaped cover plates 333 can be reduced, thereby allowing the cover plate 333 to more fully block the winding, better preventing the winding from passing over the cover plate 333, and better guiding the winding between the first guide portion 343 and the blocking portion 332.

[0157] like Figure 1As shown, in addition, another embodiment of the present disclosure further provides a cleaning robot 2, which has any of the above-mentioned roller brush assemblies 3. The present disclosure also provides a cleaning system, including a cleaning robot 2 with any of the above-mentioned roller brush assemblies 3 and a base station 1 for the cleaning robot to dock and having a cleaning assembly 4. Figure 7 As shown, the cleaning assembly 4 includes a hooking member 41, which is configured to at least hook the winding object located between the guide portion 340 and the working piece 32. The details are as described above and will not be repeated here.

[0158] like Figure 1 As shown, another embodiment of the present disclosure further provides a cleaning system, which includes a cleaning robot 2 provided with a roller brush assembly 3, and a base station 3 for the cleaning robot 2 to dock and having a cleaning assembly 4; the roller brush assembly 3 includes a roller brush body 31 provided with at least one end, and a working part 32 arranged on the roller brush body 31.

[0159] In addition, the roller brush body 31 also includes an axial limiting portion and a radial limiting portion arranged at at least one end portion, the axial limiting portion is used to limit the winding at the outermost end of the axial winding, so that the winding does not exceed the outermost end of the axial winding during the operation of the cleaning robot 2; the radial limiting portion is used to limit the winding at the innermost end of the radial winding of the entire end portion, so that the winding does not exceed the innermost end of the radial winding during the operation of the cleaning robot 2; the cleaning component 4 includes a hooking member 41 and a driving member that drives the hooking member 41 to move along a preset moving trajectory, and the preset moving trajectory covers at least the outermost end of the axial winding and the innermost end of the radial winding to cut the winding wound on the end portion. Among them, the axial limiting portion and the radial limiting portion are both structures for limiting the winding position of the winding object. The axial limiting portion is used to limit the winding range of the winding object in the axial direction, and the outermost end thereof is the farthest position axially from the middle of the roller brush body 31 when the winding object is wound. In one embodiment, this position is specifically the position of the surface of the aforementioned cover plate 333 facing the working piece 32. If it does not exceed this position, the winding object will not pass over the cover plate 333. At the same time, a radial limiting portion is also provided on the entire end portion. The radial limiting portion is used to limit the winding range of the winding object in the radial direction, and the innermost end thereof is the closest position radially to the roller brush body 31 when the winding object is wound. In one embodiment, this position is specifically the position limited by the first guide portion 343 and the blocking portion 332, that is, the position where the radial protrusion height of the support member 34 is the smallest. If it does not exceed this position, the winding object will not pass over the blocking portion 332 and be wound onto the roller brush body 31. On this basis, the hooking range of the hooking member 41 (i.e., the movement trajectory of the hooking member 41) is ensured to cover at least the outermost end of the axial winding and the innermost end of the radial winding, so as to fully hook the windings wrapped at the end. It should be noted that the "end" of the roller brush body 31 does not refer to a specific part, but is defined as: the roller brush body 31 is divided into multiple sections in the axial direction, and the "end" is the axially outermost section of the multiple sections. This section is the portion within a predetermined length from the free end of one side of the roller brush body 31 to the middle of the roller brush body 31.

[0160] The axial stopper includes at least a radially extending end surface, which forms the outermost end. Specifically, this end surface is the surface of the cover plate 333 facing the workpiece 32. Optionally, this end surface is an annular surface extending 360 degrees around the roller brush body 31. The radius of this annular surface is greater than the maximum radial height of the support member 34. This provides a more comprehensive and secure barrier to entangled material, minimizing the risk of the material exceeding the axial stopper.

[0161] Optionally, the radial limiting portion includes a guide portion and a blocking portion 332 that protrude radially relative to the outer surface of the roller brush body 31. The guide portion extends from the end of the roller brush body 31 toward the middle of the roller brush body 31 and decreases in radial height. The blocking portion 332 is located on the side of the guide portion away from the end to confine the entangled object between the guide portion and the blocking portion 332. In this structure, the guide portion is the first guide portion 343 or the second guide portion 344 described above, and the blocking portion 332 is the blocking portion 332 described above. Their specific structure, function, and interaction are described above.

[0162] like Figure 1 、 Figure 6 、 Figure 9 、 Figure 10 and Figure 11 As shown, a support member 34 is provided at the end of the roller brush body 31, and the guide portion and the blocking portion 332 are both parts of the support member 34. That is, in the cleaning system provided in this embodiment, as in the above embodiment, the blocking portion 332 is provided on the support member 34, thereby optimizing the structure.

[0163] Alternatively, the blocking portion 332 may be formed in other ways, such as Figure 12 As shown, the working piece 32 and the radial limiting portion overlap or connect in the axial direction of the roller brush body 31, and the blocking portion 332 is formed at the end of the working piece 32, so that the winding can also be limited to the innermost end of the radial limiting portion.

[0164] like Figure 11 and Figure 12 As shown, the radial limiting portion includes a support portion 345 extending along the axial direction of the roller brush body 31. The axially distributed parts of the support portion 345 have the same radial protrusion height relative to the roller brush body 31. This support portion 345 is used for winding and supporting the winding. When it is set on the roller brush body 31, it is different from the structure in the above embodiment. The support portion 345 does not have an inclined surface or arc surface that plays a guiding role. Its various axial parts are of equal height. This structure can also cooperate with the working piece 32 to collect the winding. In addition, Figure 12 In the structure shown, the axial extension length of the support portion 345 and the overlapping length of the working piece 32 can also exceed the above-mentioned preset length.

[0165] Specifically, a support member 34 is provided at the end of the roller brush body 31, radially protruding relative to the outer surface of the roller brush body 31. The support member 34 extends from the end of the roller brush body 31 toward the middle of the roller brush body 31, and the support portion 345 is a portion of the support member 34. In other words, in this embodiment, the support portion 345 is formed in the same manner as in the above embodiment, that is, by providing a plate-shaped support member 34, and the support portion 345 is a portion or the entirety of the support member 34.

[0166] In this embodiment, at least part of the working piece 32 can also be set as a hard part 323, but the difference from the above embodiment is that this hard part 323 is no longer used to be clamped by the supporting structure or only form a blocking part 332, but the hard part 323 forms the entire supporting part 345, so that it is possible to avoid setting a support member 34 on the end cover 33, and the structure of the roller brush assembly 3 can be simplified.

[0167] like Figure 13 As shown, the radial limiting portion optionally includes a support member 34 that protrudes radially from the outer surface of the roller brush body 31. The two support members 34 form a support structure that clamps at least a portion of the working member 32. The guide portion 340 of the support member 34 extends from the end of the roller brush body 31 toward the middle of the roller brush body 31 and decreases in radial height to confine the entangled material between the guide portion 340 and the working member 32. In this structure, the guide portion 340 is the second guide portion 344 mentioned above. Its specific structure, function, and interaction are described above.

[0168] like Figure 13 As shown, in one embodiment, the radial limiting portion and the axial limiting portion are the same structure, namely the limiting portion, which includes at least two support members 34 arranged along the circumference of the roller brush body 31 to clamp the ends of the working member 32. The guide portions 340 of the support members 34 extend from the ends of the roller brush body 31 toward the middle of the roller brush body 31 and decrease in radial height to confine the winding material between the guide portions 340 and the working member 32. In other words, the winding material wrapped around the support members 34 is moved axially toward the middle of the roller brush body 31 under the action of the guide portions 340, thereby changing the outermost end of the axial winding, thereby allowing it to be hooked by the hooking member. Similarly, the support members 31 can limit the innermost end of the radial winding of the winding material.

[0169] like Figure 2 As shown, in another embodiment, the support member 34 of the limiting portion includes a first support member 341 and a second support member 342, or includes a support member as shown in any of the above embodiments. With the cooperation of the support member 34 and the working member 32 or with the cooperation of the first support member 341, the second support member 342 and the working member 32, the position of the entangled object is limited to the preset moving trajectory of the hooking member to complete the cleaning.

[0170] In summary, a support member extending in the axial direction and having a radially protruding height is provided on the roller brush body, and two adjacent support members form a support structure to support the working member, and the support member and the working member at least partially overlap in the axial direction of the roller brush body, effectively preventing the working member from collapsing and preventing the entangled material from being wound around the roller brush body. At the same time, it can effectively prevent the entangled material from being wound around the gap between the support member and the working member in the axial direction, and the support member protrudes radially relative to the outer surface of the roller brush body, effectively supporting the entangled material, so that the entangled material no longer entangles around the roller brush body, making it convenient for the subsequent cleaning component to hook and cut the entangled material, thereby making it easier and more convenient to remove the entangled material, effectively preventing hair accumulation and blocking of the roller brush assembly, and improving the working performance of the roller brush assembly.
