[0053] The housing 10 is provided with an opening 12 and a receiving cavity 14, wherein the opening 12 is connected to the receiving cavity 14;

[0054] A cleaning member 16, the cleaning member 16 is rotatably connected to the housing 10, a portion of the cleaning member 16 is located in the accommodating cavity 14, and the cleaning member 16 includes bristles 18;

[0055] A self-cleaning structure 20, which includes a plurality of first cleaning units 22, which are arranged on a surface of the housing 10 facing the accommodating cavity 14 along the length direction of the cleaning member 16, and are located behind the opening 12 along the rotation direction of the cleaning member 16;

[0056] The first cleaning unit 22 is configured to clean the garbage on the bristles 18 and collect the garbage into the dust collecting member through the opening 12 when the cleaning member 16 is working.

[0057] In the above-mentioned cleaning assembly 100, when the cleaning member 16 is working, the first cleaning unit 22 can clean the garbage on the bristles 18 and collect the garbage into the dust collecting member through the opening 12, so that the garbage on the bristles 18 can be effectively cleaned, and the cleaning power of the cleaning member 16 is guaranteed to a certain extent.

[0058] Specifically, in one embodiment, the accommodating chamber 14 in the housing 10 is connected to the dust collecting part of the cleaning robot 200 through the opening 12 and the dust collecting channel, wherein the dust collecting part includes but is not limited to a dust collecting box and a dust collecting bag. The cleaning part 16 includes multiple rows of bristles 18, and each bristle 18 has a substantially consistent length or may not have a consistent length. The length direction of the cleaning part 16 is parallel to the ground. When the cleaning robot is working, the cleaning part 16 drives the bristles 18 to rotate around the rotation axis L1 of the cleaning part 16, and the rotation axis L1 of the cleaning part 16 is parallel to the ground. A part of the cleaning part 16 extends out of the accommodating chamber 14 and contacts the ground, and rolls up the dust and debris on the ground and brings them into the accommodating chamber 14. The cleaning robot may include a dust collecting component, and the dust collecting component includes a dust collecting component and a fan, and the fan is connected to the opening 12 through the dust collecting channel. When the fan is working, a negative pressure is formed in the accommodating chamber 14. When the bristles 18 rotate to the vicinity of the opening 12, the garbage (such as dust, debris, and slender objects) on the bristles 18 will be sucked into the dust collecting part from the opening 12. Wherein, part of garbage, such as elongated articles (elongated articles include but are not limited to hair) will be entangled on the bristles 18 and will not be easily sucked away. The garbage on the bristles 18 can be cleaned by the self-cleaning structure 20 and collected into the dust collecting member by the suction opening 12.

[0059] In some embodiments, the first cleaning unit 22 includes a moving unit 24 and a pushing unit 26 . The pushing unit 26 is configured to push away the garbage on the bristles 18 , and the moving unit 24 is configured to move the guide bristles 18 .

[0060] Therefore, the pushing away unit 26 can first push away the garbage on the bristles 18 to achieve the purpose of anti-entanglement, so that the undone garbage can be sucked into the dust collecting part through the opening 12, and the moving unit 24 can guide the bristles 18 to move, so that some of the garbage that has not been undone is squeezed and gathered. The garbage is pushed away and gathered many times until it is undone and sucked into the dust collecting part, so that the garbage on the bristles 18 can be effectively cleaned, and the cleaning power of the cleaning part 16 is guaranteed to a certain extent.

[0061] Optionally, combine Figures 1 to 3 In one embodiment, the self-cleaning structure 20 is installed on the top of the housing 10, the cleaning member 16 is disposed in the accommodating cavity 14 below the self-cleaning structure 20, and the opening 12 is disposed on the side wall of the accommodating cavity 14. Figure 6 In the illustrated embodiment, the cleaning member 16 can rotate in a clockwise direction when in operation.

[0062] Optionally, combine Figure 3, three rows of bristles 18 are arranged on the cleaning member 16. The cleaning member 16 also includes a body 28, which is substantially cylindrical, and each row of bristles 18 can be arranged on the body 28 in a spiral shape, a V-shape, a straight shape, an S-shape, etc. Optionally, the cleaning assembly 100 can be used as a mid-sweep assembly of a cleaning robot.

[0063] Optionally, the elongated objects include but are not limited to hair, pet hair, wool, thread-like objects, strip-like objects, etc. The thread-like objects may include but are not limited to wool, and the strip-like objects may include but are not limited to plastic strips, paper strips, straws, etc.

[0064] See also Figure 4 In some embodiments, the traveling unit 24 includes a first traveling unit 30 and a second traveling unit 32, the first traveling unit 30 is closer to the opening 12 than the second traveling unit 32, a first traveling channel 40 is formed between the pushing unit 26 and the first traveling unit 30, a second traveling channel 41 is formed between the first traveling unit 30 and the second traveling unit 32, the first traveling channel 40 is connected to the second traveling channel 41, and the cleaning component 100 is configured to allow the bristles 18 to enter the first traveling channel 40 first and then enter the second traveling channel 41.

[0065] In this way, the bristles 18 may first proceed through the first travel channel 40 , and then enter the second travel channel 41 along the first travel channel 40 .

[0066] Specifically, in one embodiment, the overall length of the first traveling unit 30 is greater than the overall length of the second traveling unit 32. When the bristles 18 are driven to rotate and travel around the rotation axis L1 of the cleaning member 16, they first enter the first traveling channel 40 formed by the first traveling unit 30 and the spreading unit 26, and contact the side walls of the first traveling unit 30 and the spreading unit 26, and move along the first traveling channel 40, and then move to the second traveling channel 41, contact the side wall of the second traveling unit 32, so as to guide the bristles 18. The bristles 18 leaving the second traveling channel 41 can return to the state before entering the first traveling channel 40.

[0067] Optionally, along the rotation direction of the cleaning member 16 from the opening 12 , one end of the first traveling unit 30 is flush with one end of the pushing unit 26 , and the other end of the first traveling unit 30 is flush with one end of the second traveling unit 32 .

[0068] In some embodiments, the first traveling unit 30 is inclined toward the center axis L2 close to the opening 12 along the rotation direction of the cleaning member 16 .

[0069] Thus, the first moving unit 30 can gather the bristles 18 toward the center axis L2 of the opening 12. On the one hand, it can facilitate the garbage to be sucked into the dust collecting member through the opening 12. On the other hand, it can prevent the garbage on the bristles 18 from flowing to the two ends of the cleaning member 16 and causing the garbage to be entangled on the rotating shaft of the cleaning member 16 to a certain extent.

[0070] Specifically, please combine Figure 4 When the bristles 18 enter the first travel channel 40 or the second travel channel 41, since the first travel unit 30 is inclined along the rotation direction of the cleaning member 16 toward the central axis direction close to the opening 12, the bristles 18 are squeezed by the side wall of the first travel unit 30, so that the bristles 18 are gathered toward the central axis L2 of the opening 12. On the one hand, it is convenient for the garbage to be sucked into the dust collecting member through the opening 12. On the other hand, it can prevent the garbage on the bristles 18 from flowing to the two ends of the cleaning member 16 to a certain extent and causing the garbage to be entangled on the rotating shaft of the cleaning member 16.

[0071] See also Figure 5 and Figure 6 In some embodiments, the self-cleaning structure 20 includes a facing surface 34 facing the opening 12, and the end surfaces 36 of the first moving unit 30 and the spreading unit 26 facing the opening 12 are located on the facing surface 34, and the angle formed between the bristles 18 in contact with the facing surface 34 and the facing surface 34 is an acute angle.

[0072] In this way, the garbage on the bristles 18 can be effectively removed, and the garbage is not easily cut or stuck.

[0073] Specifically, in one embodiment, when the bristles 18 rotate to the self-cleaning structure 20, they first contact the end faces 36 of the first traveling unit 30 and the pushing unit 26, and the end faces 36 are located at the meeting face 34. The angle a formed between the bristles 18 contacting the meeting face 34 and the meeting face 34 is an acute angle, which can prevent garbage from being cut off by the end face 36 or being stuck in the gap between the end face 36 and the housing 10 to cause blockage.

[0074] Optionally, the first moving unit 30 and the end surface 36 of the pushing unit 26 are rounded at the parts where the bristles 18 first come into contact, so as to avoid the garbage being cut off to a certain extent.

[0075] See also Figure 7 In some embodiments, the end surface 36 of the first traveling unit 30 facing the opening 12 is gradually expanded in a direction away from the rotation axis L1 of the cleaning member 16, and / or;

[0076] The end surface 36 of the pushing unit 26 facing the opening 12 is in a shape that gradually expands in a direction away from the rotation axis L1 of the cleaning member 16 .

[0077] In this way, the garbage will be blocked on the end surface 36 after being pushed away, so as to be sucked into the dust collecting member through the opening 12. The end surface 36 is configured to be gradually expanded in the direction away from the rotation axis L1 of the cleaning member 16 to ensure the passability of the bristles 18.

[0078] Specifically, please combine Figures 5 to 7 In one embodiment, the end surface 36 of the first moving unit 30 and the pushing unit 26 facing the opening 12 includes a substantially triangular area, and the portion where the end surface 36 first contacts the bristles 18 is a triangular contact angle 38. Therefore, the end surface 36 is gradually expanded in a direction away from the rotation axis of the cleaning member 16, which is conducive to hooking and pushing away the garbage on the bristles 18. When the garbage on the bristles 18 is untangled, the garbage is subjected to the force exerted by the end surface 36 and remains on the end surface 36. At the same time, it is subjected to the negative pressure of the fan in the opening 12 facing the facing surface 34, and the garbage is separated from the bristles 18 and sucked into the dust collecting member.

[0079] Alternatively, in some embodiments, the end surface 36 may be other shapes having a certain area, including but not limited to a trapezoid and a semicircle.

[0080] See also Figure 4 In some embodiments, the distance between the first traveling unit 30 and the second traveling unit 32 gradually decreases in a direction away from the opening 12 .

[0081] In this way, the garbage on the bristles 18 can be squeezed out.

[0082] Specifically, in one embodiment, after the bristles 18 contact the self-cleaning structure 20, they first move along the first travel channel 40, then enter the second travel channel 41, and contact the side of the second travel unit 32. Figure 4 , the distance between the first traveling unit 30 and the second traveling unit 32 changes from D1 to D2 in the direction away from the opening 12, wherein D2 is smaller than D1. As the distance between the first traveling unit 30 and the second traveling unit 32 gradually decreases, the force exerted by the side surfaces of the first traveling unit 30 and the second traveling unit 32 on the garbage on the bristles 18 becomes increasingly greater, thereby achieving the effect of squeezing the garbage.

[0083] See also Figure 4 In some embodiments, an extension line of the first traveling unit 30 and an extension line of the second traveling unit 32 intersect.

[0084] In this way, the garbage on the bristles 18 can be gathered.

[0085] Specifically, please combine Figure 4In one embodiment, the extension line of the first traveling unit 30 and the extension line of the second traveling unit 32 intersect at the intersection point A in the direction away from the opening 12. When the bristles 18 rotate to the end of the second traveling channel 41 formed between the first traveling unit 30 and the second traveling unit 32, the garbage on the bristles 18 will be gathered.

[0086] Optionally, a gap is left between the end of the first traveling unit 30 and the end of the second traveling unit 32 to ensure that the bristles 18 can pass smoothly to a certain extent.

[0087] See also Figure 4 and Figure 8 In some embodiments, a travel channel is formed between the pushing unit 26 and the traveling unit 24, and the bristles 18 are interference fit with the side wall of the travel channel.

[0088] In this way, the garbage on the bristles 18 can be subjected to frictional force toward the dust outlet, so that the garbage and the bristles 18 can be separated from each other.

[0089] Specifically, in one embodiment, the traveling unit 24 includes a first traveling unit 30 and a second traveling unit 32, a first traveling channel 40 is formed between the pushing unit 26 and the first traveling unit 30, a second traveling channel 41 is formed between the first traveling unit 30 and the second traveling unit 32, and the first traveling channel 40 and the second traveling channel 41 constitute a traveling channel. The traveling channel is used to guide the bristles 18 to travel.

[0090] When the bristles 18 move in the travel channel, because the bristles 18 are in interference fit with the side wall of the travel channel, the garbage on the bristles 18 is also subjected to the friction force of the side of the spreading unit 26 and the first travel unit 30. The direction of the friction force is opposite to the travel direction of the bristles 18, which can help separate the garbage from the bristles 18.

[0091] Optionally, the bristles 18 include a gelatin shell, and the bristles 18 are interference fit with the side wall of the travel channel. The gelatin shell will be squeezed and deformed, which is conducive to the bristles 18 passing through the travel channel.

[0092] In some embodiments, the interference fit between the bristles 18 and the side wall of the travel channel ranges from [2.3 mm, 3.5 mm], that is, the interference fit is greater than or equal to 2.3 mm (millimeter) and less than or equal to 3.5 mm (millimeter).

[0093] In this way, the garbage on the bristles 18 can be subjected to sufficient friction to move relative to the bristles 18 toward the opening 12 , while also preventing the garbage from being subjected to excessive pressure from the side walls toward the bristles 18 and sticking to the bristles 18 .

[0094] Specifically, the distance between the side of the spreading unit 26 and the side of the first traveling unit 30 gradually decreases in the direction away from the opening 12, that is, the width of the first traveling channel 40 formed between the spreading unit 26 and the first traveling unit 30 gradually decreases. When the bristles 18 are at the entrance of the first traveling channel 40, the interference fit between the bristles 18 and the side wall of the first traveling channel 40 can be 2.3 mm; and when the bristles 18 are in the first traveling channel 40 at the end of the spreading unit 26, the interference fit between the bristles 18 and the side wall of the first traveling channel 40 can be 3.5 mm.

[0095] The distance between the side of the second traveling unit 32 and the side of the first traveling unit 30 gradually decreases in the direction away from the opening 12, that is, the width of the second traveling channel 41 formed between the second traveling unit 26 and the first traveling unit 30 gradually decreases. When the bristles 18 are at the entrance of the second traveling channel, the interference amount of the interference fit between the bristles 18 and the side wall of the second traveling channel 41 can be 2.3 mm, and when the bristles 18 are at the end of the second traveling channel 41, the interference amount of the interference fit between the bristles 18 and the side wall of the second traveling channel 41 can be 3.5 mm.

[0096] Please combine Figure 6 Based on the commonly used cleaning parts in the industry, the length H of the bristles of the cleaning parts is 14.5 mm, and the interference between the cleaning parts and the side walls of the travel channel can be 2.3 mm.

[0097] In some examples, the interference fit between the bristles 18 and the side wall of the travel channel may be 2.3 mm, 2.5 mm, 2.7 mm, 2.9 mm, 3.0 mm, 3.2 mm, 3.4 mm, 3.5 mm or other values ​​of [2.3 mm, 3.5 mm].

[0098] Optionally, in some embodiments, the distance between the side of the pushing unit 26 and the side of the first traveling unit 30 remains unchanged, that is, the width of the first traveling channel 40 remains unchanged, and the interference fit between the bristles 18 and the side wall of the first traveling channel 40 can be selected from any value in [2.3mm, 3.5mm].

[0099] Optionally, in some embodiments, the distance between the side of the second traveling unit 32 and the side of the first traveling unit 30 remains unchanged, that is, the width of the second traveling channel 41 remains unchanged, and the interference fit between the bristles 18 and the side wall of the second traveling channel 41 can be selected from any value in [2.3mm, 3.5mm].

[0100] Optionally, the cleaning member 16 further comprises a rubber strip 19, and along the circumferential direction of the cleaning member 16, one rubber strip is between two rows of bristles 18. Under the condition of a suitable distance from the rubber strip 19, the interference between the bristles 18 and the side wall of the travel channel can be increased. Figure 6a , the outer radius of the bristles R1 - the outer radius of the rubber strip R2 = the distance between the self-cleaning structure and the rubber strip + the interference between the side wall of the travel channel and the bristles, that is, the interference between the side wall of the travel channel and the bristles = the outer radius of the bristles R1 - the outer radius of the rubber strip R2 - the distance between the comb teeth and the rubber strip.

[0101] See also Figure 7 In some embodiments, the orthographic projections of the traveling unit 24 and the pushing unit 26 on a vertical plane are connected to each other, and the vertical plane is parallel to the rotation axis of the cleaning member 16 .

[0102] In this way, the garbage on each bristle 18 can come into contact with the self-cleaning structure 20 , thereby improving the cleaning power of the self-cleaning structure 20 .

[0103] Specifically, in one embodiment, please refer to Figure 1 When the cleaning member 16 is working, the cleaning member 16 rotates around the rotation axis L1, and the vertical plane is perpendicular to the ground and parallel to the rotation axis L1 of the cleaning member 16. The orthographic projections of the traveling unit 24 and the expelling unit 26 on the vertical plane are connected to each other, that is, there is no gap perpendicular to the vertical plane between the first traveling unit 30 and the second traveling unit 32, and between the traveling unit 24 and the expelling unit 26, so that each bristle 18 and the garbage on the bristles 18 are in contact with the traveling unit 24 or the expelling unit 26.

[0104] See also Figure 4 and Figure 5 In some embodiments, the self-cleaning structure 20 includes a second cleaning unit 42, and along the length direction of the cleaning member 16, one second cleaning unit 42 is located between two adjacent first cleaning units 22;

[0105] The second cleaning unit 42 includes a pushing unit 26 and two first traveling units 30 . Along the length direction of the cleaning member, the pushing unit is located between the two first traveling units 30 .

[0106] In this way, the second cleaning unit can be used to position the self-cleaning structure 20 and the opening 12 .

[0107] Specifically, please combine Figure 4 In one embodiment, the self-cleaning structure 20 includes a second cleaning unit 42, and a plurality of first cleaning units 22 are arranged at intervals along the length direction of the cleaning member 16. The second cleaning unit 42 is located between two adjacent first cleaning units 22, and the plurality of first cleaning units 22 are divided into two left and right parts. The second cleaning unit 42 includes a spreading unit 26, and a first moving unit 30 is respectively arranged on the left and right of the spreading unit 26. Optionally, the two first moving units 30 are symmetrically arranged on both sides of the spreading unit 26. The length direction of the cleaning member 16 can be the left and right direction shown in the figure.

[0108] The relative position of the second cleaning unit 42 and the central axis L2 of the opening 12 can be used to position the self-cleaning structure 20 and the opening 12, thereby facilitating the installation of the self-cleaning structure 20.

[0109] In one embodiment, the self-cleaning structure 20 includes a plurality of second cleaning units 42, and one second cleaning unit 42 is located between two adjacent first cleaning units 22. Thus, the first cleaning unit 22 can be configured according to the position of the second cleaning unit 42, so that the self-cleaning structure 20 can be positioned relative to the opening 12, so that the garbage can be gathered at a desired position to facilitate suction into the opening 12.

[0110] See also Figure 4 In some embodiments, the pushing away unit 26 includes a first pushing away portion 44 and a first channel portion 46 , the first pushing away portion 44 is closer to the opening 12 than the first channel portion 46 , the first channel portion 46 is connected to the first pushing away portion 44 , and the extension direction of the first channel portion 46 is parallel to the rotation direction of the cleaning member 16 .

[0111] In this way, the pushing unit 26 will not substantially change the travel path of the bristles 18 .

[0112] Specifically, in one embodiment, the first pushing portion 44 faces the opening 12, and when the bristles 18 rotate to the self-cleaning structure 20, the garbage on the bristles 18 first contacts the first pushing portion 44. The first pushing portion 44 and the first channel portion 46 are sequentially connected along the rotation direction of the cleaning member 16.

[0113] Optionally, the first channel portion 46 of the second cleaning unit 42 is longer than the first channel portion 46 of the first cleaning unit 22 , so as to cooperate with the first traveling units 30 on both sides of the second cleaning unit 42 to form the first traveling channel 40 .

[0114] See also Figure 4 In some embodiments, the first traveling unit 30 includes a second spreading portion 48 and a second channel portion 50, the second spreading portion 48 is closer to the opening 12 than the second channel portion 50, a first traveling channel 40 is formed between the second channel portion 50 and the first channel portion 46, and the second channel portion 50 is inclined toward the central axis L2 close to the opening 12 along the rotation direction of the cleaning member 16;

[0115] The second channel portion 50 is connected to the second pushing portion 48 , and an extension line of the second channel portion 50 of the first cleaning unit 22 intersects with an extension line of the first channel portion 46 of the second cleaning unit 42 .

[0116] In this way, the garbage on the bristles 18 is acted upon by the second channel portion 50 to move toward the central axis L2 of the opening 12 so as to gather toward the opening 12 and be sucked into the opening 12 .

[0117] Specifically, in one embodiment, the second pushing away portion 48 has a similar function to the first pushing away portion 44, and can also push away the garbage on the bristles 18. Figure 4 For the first cleaning unit 22 located on the left side of the second cleaning unit 42, its second channel portion 50 is inclined to the right along the rotation direction of the cleaning member 16; and for the first cleaning unit 22 located on the right side of the second cleaning unit 42, its second channel portion 50 is inclined to the left along the rotation direction of the cleaning member 16. As a result, the garbage on the bristles 18 is subjected to a force in the direction of the central axis L2 of the opening 12, which can make the garbage gather toward the opening 12 and be more easily sucked into the opening 12.

[0118] See also Figure 4 In some embodiments, for the first cleaning unit 22, a second travel channel 41 is formed between the second travel unit 32 and the first channel portion 46, and the intersection of the extension line of the second channel portion 50 of the first cleaning unit 22 and the extension line of the second travel unit 32 is located on the extension line of the first channel portion 46.

[0119] In this way, the combined force of the second channel portion 50 and the second traveling unit 32 can squeeze and gather the garbage on the bristles 18 .

[0120] Specifically, in one embodiment, the intersection A of the extension line of the second passage portion 50 of the first cleaning unit 22 and the extension line of the second traveling unit 32 is located on the extension line of the first passage portion 46 .

[0121] The second channel portion 50 of the first cleaning unit 22 and the second traveling unit 32 form a second traveling channel 41 that gradually contracts along the rotation direction of the cleaning member 16. When the bristles 18 continue to move along the second traveling channel 41, the garbage is subjected to an increasingly greater combined force from the second channel portion 50 and the side of the second traveling unit 32, and is gradually squeezed and gathered. As a result, the garbage is first pushed away by the pushing unit 26, and then squeezed and gathered. Repeating this process can untangle the garbage entangled on the bristles 18 and be sucked into the dust collecting member from the opening 12, thereby realizing the anti-entanglement function of the bristles 18.

[0122] Optionally, in the second travel channel between the second channel portion 50 and the second travel unit 32 , the interference fit between the bristles 18 and the side wall of the second travel channel 41 may be greater than or equal to 2.3 mm and less than or equal to 3.5 mm (millimeter).

[0123] See also Fig. 9In some embodiments, the cross-sections of the first channel portion 46 , the second channel portion 50 , and the second traveling unit 32 in the vertical direction are gradually expanded in a direction away from the rotation axis of the cleaning member 16 .

[0124] In this way, the frictional resistance of the self-cleaning structure 20 to the bristles 18 can be reduced, while the noise caused by friction can be reduced.

[0125] Specifically, in one embodiment, the cross-sections of the first channel portion 46 , the second channel portion 50 and the second traveling unit 32 in the vertical direction may be substantially triangular, and a corner of the triangle facing the accommodating cavity 14 is chamfered to prevent garbage from being cut.

[0126] Optionally, the cross section in the vertical direction may be a right-angled trapezoid, an oblique trapezoid, or an isosceles trapezoid. Optionally, the cross sections in the vertical direction of the first channel portion 46, the second channel portion 50, and the second traveling unit 32 may be the same or different.

[0127] The movement path of the bristles 18 through the self-cleaning structure 20 is roughly as follows:

[0128] Please refer to Figure 4 and Figure 6 In one embodiment, the cleaning member 16 can rotate clockwise, and the bristles 18 first enter from between the second prying portion 48 of the first traveling unit 30 and the first prying portion 44 of the prying unit 26, and move along the first traveling channel 40 between the second channel portion 50 of the first traveling unit 30 and the first channel portion 46 of the prying unit 26. After the bristles 18 pass through the end of the first channel portion 46, they enter the second traveling channel 41 between the second channel portion 50 and the second traveling unit 32, and finally leave the self-cleaning structure 20 from the end of the second channel portion 50 and the second traveling unit 32.

[0129] Please combine Figure 4 , part of the bristles 18 enters the self-cleaning structure 20 from between the first spreading part 44 of the spreading unit 26 of a first cleaning unit 22 and the second spreading part 48 of the first moving unit 30 of the adjacent first cleaning unit 22, and then enters the third moving channel 43 formed between the first channel part 46 of the spreading unit 26 of the first cleaning unit 22 and the second channel part 50 of the first moving unit 30 of the adjacent first cleaning unit 22, and enters the second moving channel 41 from the third moving channel 43. Although the movement route of this part of the bristles 18 is different from the above route, the garbage on this part of the bristles 18 can also be spread away by the spreading unit 26, and will also be squeezed and gathered by the combined force of the second channel part 50 and the second moving unit 32.

[0130] Furthermore, please combine Figure 3The bristles 18 are arranged in a wave or spiral shape on the body 28, so different bristles 18 enter the self-cleaning structure 20 in a certain order, which can avoid the blockage caused by two bristles 18 entering the same travel channel at the same time to a certain extent.

[0131] In summary, in the cleaning component 100 of the embodiment of the utility model, the self-cleaning structure 20 includes a plurality of first cleaning units 22, which can disperse the processing load (garbage), realize multi-threaded synchronous processing, improve processing efficiency, and greatly reduce the probability of tangling of garbage.

[0132] Furthermore, as the cleaning member 16 continuously rotates around the rotation axis L1 and passes through the self-cleaning structure 20 multiple times, each bristle 18 will enter the self-cleaning structure 20 from the first travel channel between the second prying portion 48 of the first travel unit 30 and the first prying portion 44 of the prying unit 26 at least once to achieve the best cleaning effect.

[0133] A cleaning robot according to an embodiment of the present utility model comprises the cleaning assembly 100 according to any one of the above embodiments.

[0134] In the above cleaning robot, when the cleaning member 16 is working, the first cleaning unit 22 can clean the garbage on the bristles 18 and collect the garbage into the dust collecting member through the opening 12, so that the garbage on the bristles 18 can be effectively cleaned, and the cleaning power of the cleaning member 16 is guaranteed to a certain extent.

[0135] In some embodiments, the cleaning robot includes a dust collection component, which includes a dust collecting part and a fan. The dust collecting part is connected to the opening 12 through a dust collecting channel. When the cleaning part 16 is working, the fan is started to form a negative pressure at the opening 12 so that the garbage falling from the bristles 18 is sucked into the dust collecting part through the opening 12 and the dust collecting channel.

[0136] Thereby, the dust dropped from the bristles 18 can be sucked into the dust collecting member.

[0137] Specifically, the cleaning robot may include a body, a dust collecting assembly and a cleaning assembly 100 are mounted on the body, and the dust collecting member may be connected to the opening 12 through a dust collecting channel. When the cleaning member 16 is working, the cleaning member 16 rotates along the rotation axis L1, and the fan is started to form a negative pressure at the opening 12 so that the garbage falling from the bristles 18 is sucked into the dust collecting member through the opening 12 and the dust collecting channel, so that the bristles 18 can be cleaned.
