[0059] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0060] Related technologies propose setting cleaning teeth in the accommodating cavity of the cleaning component to remove hair and other debris from the cleaning component during the cleaning process. However, the cleaning teeth in the related technologies have the problem of poor cleaning effect, and there is a need for improvement.

[0061] The cleaning apparatus according to an embodiment of the present disclosure is described below with reference to Figures 1-21.

[0062] The cleaning equipment in the embodiments of this disclosure is preferably, but not limited to, a sweeping robot and a sweeping and mopping robot.

[0063] As shown in Figures 1-21, the cleaning device of this embodiment includes a body 1, a cleaning component 2, and a comb component 3.

[0064] The body 1 has a receiving cavity 11, and a dust collection port 12 is provided on the wall of the receiving cavity 11. For example, as shown in Figures 1 and 2, the receiving cavity 11 extends in the left-right direction in Figures 1 and 2, and the receiving cavity 11 opens at the bottom surface of the body 1. The cleaning component 2 sweeps dirt from the surface to be cleaned, such as the ground, into the receiving cavity 11 through the opening. As shown in Figures 1 and 2, in this example, the opening of the receiving cavity 11 is generally rectangular.

[0065] The cleaning component 2 is rotatably disposed within the receiving cavity 11 about its central axis. The cleaning component 2 has a cleaning element 21 for cleaning the surface to be cleaned. For example, as shown in FIG1, the cleaning component 2 is disposed within the receiving cavity 11 and extends in the left-right direction; in other words, the central axis of the cleaning component 2 extends in the left-right direction, or more specifically, the axial direction of the cleaning component 2 is in the left-right direction. The cleaning component 2 is rotatable about the left-right direction relative to the receiving cavity 11.

[0066] The cleaning component 2 may be a main brush, and the sweeping component 21 may be bristles and / or rubber strips provided on the rotating shaft of the main brush. The sweeping component 21 is used to contact the surface to be cleaned, such as the ground, to sweep the surface to be cleaned.

[0067] The comb component 3 is disposed on the wall of the receiving cavity 11 and includes a plurality of comb teeth 31 for cleaning the cleaning component 21. The comb teeth 31 are used to clean the cleaning component 21, for example, to clean debris such as hair and fibers entangled on the cleaning component 21.

[0068] The comb teeth 31 include a first row of comb teeth 31 and a second row of comb teeth 31. The first row of comb teeth 31 and the second row of comb teeth 31 are arranged side by side along the circumference of the receiving cavity 11 (e.g., the up-down direction shown in Figures 2 and 3). The first row of comb teeth 31 includes a plurality of first comb teeth 32 spaced apart along the axial direction of the cleaning component 2 (i.e., the longitudinal direction of the receiving cavity 11, e.g., the left-right direction shown in Figures 2 and 3). The second row of comb teeth 31 includes a plurality of second comb teeth 33 spaced apart along the axial direction of the cleaning component 2. The first comb teeth 32 and the second comb teeth 33 are staggered along the axial direction of the cleaning component 2 (i.e., staggered and not aligned in the circumference of the receiving cavity 11).

[0069] When the cleaning component 2 rotates, the first comb tooth 32 and the second comb tooth 33 come into contact with the sweeping component 21 in sequence. That is, the sweeping component 21 passes over the first comb tooth 32 and the second comb tooth 33 in sequence. Since the first comb tooth 32 and the second comb tooth 33 are arranged alternately along the axial direction of the cleaning component 2, the part of the sweeping component 21 that passes through the gap between adjacent first comb teeth 32 when it passes over the first comb tooth 32 will definitely pass over the second comb tooth 33. Thus, the sweeping component 21 is cleaned by the first comb tooth 32 and the second comb tooth 33, that is, debris such as hair and fibers attached to or wrapped around the sweeping component 21 is cleaned.

[0070] In the cleaning device of this embodiment, the first row of comb teeth and the second row of comb teeth sequentially clean the debris entangled on the cleaning component. The first comb teeth of the first row of comb teeth and the second comb teeth of the second row of comb teeth are arranged alternately. When the cleaning component rotates, the part passing between adjacent first comb teeth will be cleaned by the second comb teeth, which improves the cleaning effect of the comb teeth on the debris entangled on the cleaning component. Therefore, the cleaning device of this embodiment has a good cleaning effect of the comb teeth on the cleaning component.

[0071] In some embodiments, the comb component 3 further includes a mounting plate 34, the comb teeth 31 are disposed on the mounting plate 34, and the wall of the accommodating cavity 11 is provided with a mounting groove 13, and the mounting plate 34 is detachably installed in the mounting groove 13.

[0072] As shown in Figures 2 and 3, the comb component 3 includes a mounting plate 34, with comb teeth 31 protruding from the surface of the mounting plate 34. In some embodiments, the comb teeth 31 and the mounting plate 34 are integrally injection molded, thereby reducing costs and making the comb component 3 easy to process.

[0073] The accommodating cavity 11 has a mounting groove 13 on its wall. The wall of the accommodating cavity 11 and the mounting groove 13 can be arc-shaped structures, and the mounting plate 34 can be an arc-shaped plate adapted to the wall of the accommodating cavity 11 and the mounting groove 13. In some embodiments, the axial direction of the arc-shaped accommodating cavity 11 wall, the mounting groove 13 and the mounting plate 34 is consistent with the axial direction of the cleaning component 2, which is the left-right direction shown in Figures 2 and 3.

[0074] The mounting plate 34 is detachably installed in the mounting groove 13. In some embodiments, the mounting plate 34 is snapped into the mounting groove 13 by a snap-fit ​​structure to facilitate quick installation and removal of the mounting plate 34 and to facilitate the processing of the mounting plate 34.

[0075] In some embodiments, the surface of the mounting plate 34 with comb teeth 31 is flush with the wall surface of the receiving cavity 11, and the comb teeth 31 protrude from the wall surface of the receiving cavity 11, thereby ensuring that the comb teeth 31 contact the cleaning member 21, while avoiding the mounting plate 34 contacting the cleaning member 21 and blocking the cleaning member 21.

[0076] In some embodiments, as shown in Figures 2 and 3, along the rotation direction of the cleaning component 2, the first comb tooth 32 is located downstream of the dust collection port 12, and the second comb tooth 33 is located downstream of the first comb tooth 32.

[0077] During the rotation of the cleaning component 2, the cleaning component 21 first cleans the surface to be cleaned through the opening of the receiving cavity 11, and then passes through the dust collection port 12. The cleaned dirt is sucked into the dust collection port 12. Then the cleaning component 21 reaches the comb teeth 31 and passes over the first comb teeth 32 and the second comb teeth 33 in sequence. Thus, the first comb teeth 32 and the second comb teeth 33 remove the debris wrapped around the cleaning component 21 from the cleaning component 21. The removed debris is sucked into the dust collection port 12.

[0078] The distance L1 between the first comb tooth 32 and the dust collection port 12 is greater than 0 mm and less than or equal to 3 mm, for example, 1 mm, 1.5 mm, 2 mm, or 3 mm. If the distance L1 between the first comb tooth 32 and the dust collection port 12 is less than or equal to 0 mm, the first comb tooth 32 extending into the dust collection port 12 will affect the airflow entering the dust collection port 12, increasing wind resistance. If the distance L1 between the first comb tooth 32 and the dust collection port 12 is greater than 3 mm, the cleaned debris will not easily enter the dust collection port, affecting the cleaning effect.

[0079] As shown in Figures 3, 6, 9, and 12, the distance L2 between the first comb tooth 32 and the second comb tooth 33 is greater than or equal to 1 mm and less than or equal to 6 mm, for example, 1 mm, 3 mm, 5 mm, or 6 mm. If the distance L2 between the first comb tooth 32 and the second comb tooth 33 is less than 1 mm, the cleaning part 21 cannot bounce back in time after passing the first comb tooth 32 and passes the second comb tooth 33, affecting the cleaning effect of the second comb tooth 33 on the cleaning part 21 and the cleaning efficiency of the comb tooth 31 on the cleaning part 21. If the distance L2 between the first comb tooth 32 and the second comb tooth 33 is greater than 6 mm, the debris cleaned by the second comb tooth 33 is not easy to enter the dust collection port, affecting the cleaning effect.

[0080] In some embodiments, a dust guide groove 14 is provided on the wall of the accommodating cavity 11. The dust guide groove 14 surrounds the dust collection port 12. The side wall of the dust guide groove 14 adjacent to the first comb tooth 32 is transitioned to the wall of the accommodating cavity 11 by a first rounded corner 15. The side wall of the dust guide groove 14 adjacent to the first comb tooth 32 is transitioned to the first comb tooth 32 by a first rounded corner 15 and a second rounded corner 16. The protruding directions of the first rounded corner 15 and the second rounded corner 16 are opposite.

[0081] As shown in Figures 2 and 3, a dust guiding groove 14 is provided on the wall of the accommodating cavity 11, surrounding the dust collection port 12. The dust guiding groove 14 can be funnel-shaped or snout-shaped, and the dust collection port 12 is located at the bottom of the dust guiding groove 14, thereby guiding the cleaned debris towards the dust collection port 12. In some embodiments, the dust guiding groove 14 extends in the left-right direction, and the dust collection port 12 is located in the middle of the dust guiding groove 14 in the left-right direction.

[0082] As shown in Figure 4, the dust guide groove 14 is adjacent to the side wall of the first comb tooth 32. That is, as shown in Figure 3, the upper side wall of the dust guide groove 14 and the wall of the receiving cavity 11 are transitioned by the first rounded corner 15. The upper side wall of the dust guide groove 14 and the first comb tooth 32 are transitioned by the first rounded corner 15 and the second rounded corner 16. The second rounded corner 16 is located at the root of the first comb tooth 32. The first rounded corner 15 protrudes into the receiving cavity 11, and the second rounded corner 16 protrudes outward from the receiving cavity 11. In other words, it protrudes into the wall of the receiving cavity 11.

[0083] The first rounded corner 15 improves the smoothness of the gas flow from the first comb tooth 32 into the dust guide groove 14, which is conducive to the entry of debris into the dust guide groove 14 and its collection by the dust collection port 12. The second rounded corner 16 is conducive to the removal of debris such as hair and fibers from the first comb tooth 32.

[0084] In some embodiments, the height H1 of the first comb tooth 32 is greater than or equal to the height H2 of the second comb tooth 33.

[0085] As shown in Figures 5-17, the comb teeth 31 have a top surface and a bottom surface that are arranged opposite each other along the radial direction of the cleaning component 2 (i.e., the radial direction of the accommodating cavity 11 and the mounting plate 34). The bottom surface coincides with the plate surface of the mounting plate 34, so that it is flush with the wall surface of the accommodating cavity 11. The distance between the top surface and the plate surface of the mounting plate 34 is the height of the comb teeth 31. In other words, the height of the comb teeth 31 is the dimension of the comb teeth 31 along the radial direction of the accommodating cavity 11.

[0086] The comb teeth 31 have a first tooth end 311 and a second tooth end 312 that are axially opposite to the cleaning component 2. The first tooth end 311 of the comb teeth 31 is closer to the dust collection port 12 than the second tooth end 312, and the second tooth end 312 of the comb teeth 31 is farther away from the dust collection port 12 than the first tooth end 311.

[0087] As shown in Figures 7, 10, and 13, the top surfaces of the first comb tooth 32 and the second comb tooth 33 are generally parallel to the surface of the mounting plate 34, that is, generally parallel to the wall surface of the accommodating cavity 11. The height H1 of the first comb tooth 32 is greater than or equal to the height H2 of the second comb tooth 33.

[0088] As shown in Figures 15 and 17, the top surfaces of the first comb tooth 32 and the second comb tooth 33 are both inclined. The height of the first tooth end 311 of the first comb tooth 32 is greater than the height of the second tooth end 312, the height of the first tooth end 311 of the second comb tooth 33 is greater than the height of the second tooth end 312, and the height of the first tooth end 311 of the first comb tooth 32 is greater than or equal to the height of the first tooth end 311 of the second comb tooth 33. In other words, the maximum height H1 of the first comb tooth 32 is greater than or equal to the maximum height H2 of the second comb tooth 33.

[0089] During the rotation of the cleaning component 2, the sweeping component 21 sequentially passes over the first comb tooth 32 and the second comb tooth 33. The height H1 of the first comb tooth 32 is greater than or equal to the height H2 of the second comb tooth 33, so that debris on the sweeping component 21, especially larger debris, is mainly cleaned off by the first comb tooth 32, making it easier for debris to enter the dust collection port 12, while preventing larger debris from getting stuck between two adjacent comb teeth 31. At the same time, the second comb tooth 33 can also block the airflow and reduce the resistance to the rotation of the sweeping component 21.

[0090] In some embodiments, the thickness T1 of the top surface of the comb tooth 31 is less than the thickness T2 of the bottom surface of the comb tooth 31, and the length M1 of the top surface of the comb tooth 31 is less than the length M2 of the bottom surface of the comb tooth 31.

[0091] As shown in Figures 5-17, the dimension of the comb teeth 31 along the axial direction of the cleaning component 2 is the thickness of the comb teeth 31; in other words, the dimension of the comb teeth 31 along the longitudinal direction of the receiving cavity 11 is the thickness of the comb teeth 31. The dimension of the comb teeth 31 along the circumferential direction of the cleaning component 2 is the length of the comb teeth 31; in other words, the dimension of the comb teeth 31 along the axial direction of the receiving cavity 11 is the length of the comb teeth 31.

[0092] As shown in Figures 6, 9, 12, and 15, the comb teeth 31 are inclined on at least one side along the axial direction of the cleaning component 2; in other words, at least one side of the comb teeth 31 on both the left and right sides is inclined. In some embodiments, both sides are inclined, so that the thickness T1 of the top surface of the comb teeth 31 is less than the thickness T2 of the bottom surface of the comb teeth 31, thereby making it easier for the comb teeth 31 to enter the cleaning component 21 and reducing the rotational resistance of the cleaning component 21.

[0093] It should be noted that the thickness of the comb teeth 31 can be constant or variable along the circumference of the cleaning component 2. When the thickness of the comb teeth 31 varies, the thickness T1 of the top surface of the comb teeth 31 being less than the thickness T2 of the bottom surface of the comb teeth 31 means that, within the cross-section of the comb teeth 31 parallel to the axial direction of the cleaning component 2, the thickness T1 of the top surface of the comb teeth 31 within the cross-section is less than the thickness T2 of the bottom surface of the comb teeth 31 within the cross-section.

[0094] As shown in Figures 6, 9, 12, and 15, the end face of the first tooth end 311 and / or the end face of the second tooth end 312 of the comb tooth 31 are inclined, so that the length M1 of the top surface of the comb tooth 31 is less than the length M2 of the bottom surface of the comb tooth 31, thereby making it easier for the comb tooth 31 to enter the cleaning member 21 and reducing the rotational resistance of the cleaning member 21.

[0095] In some embodiments, the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 are both greater than or equal to 0.5 mm and less than or equal to 5 mm, the thickness T1 of the top surface of the comb tooth 31 is greater than or equal to 0.5 mm and less than or equal to 3 mm, the thickness T2 of the bottom surface of the comb tooth 31 is greater than or equal to 0.6 mm and less than or equal to 7 mm, and the length M1 of the top surface of the comb tooth 31 is less than or equal to 3 mm.

[0096] As shown in Figures 6, 9, 12, and 15, the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 are both greater than or equal to 0.5 mm and less than or equal to 5 mm, for example, 0.5 mm, 1.8 mm, 3.5 mm, and 5 mm.

[0097] It should be noted that the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 can be constant or variable. When the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 change, they must be within the range of greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0098] When the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 are less than 0.5 mm, debris easily gets stuck between them. When the distance S1 between the top surfaces of adjacent first comb teeth 32 and the distance S2 between the top surfaces of adjacent second comb teeth 33 are greater than 5 mm, the cleaning efficiency of the first comb teeth 32 and second comb teeth 33 on the sweeping component 21 is low, and the airflow between them is too small, affecting the entry of debris into the dust inlet.

[0099] The thickness T1 of the top surface of the comb tooth 31 is greater than or equal to 0.5 mm and less than or equal to 3 mm, for example, 0.5 mm, 1.2 mm, 2 mm, or 3 mm. The thickness T2 of the bottom surface of the comb tooth 31 is greater than or equal to 0.6 mm and less than or equal to 7 mm, for example, 0.6 mm, 1.8 mm, 5 mm, 6.5 mm, or 7 mm.

[0100] If the thickness T1 of the top surface of the comb teeth 31 is less than 0.5 mm and the thickness T2 of the bottom surface is less than 0.6 mm, the comb teeth 31 are easily worn, affecting the cleaning efficiency of the sweeping component 21. If the thickness T1 of the top surface of the comb teeth 31 is greater than 3 mm and the thickness T2 of the bottom surface is greater than 7 mm, the rotational resistance of the sweeping component 21 is greater, affecting the cleaning efficiency of the sweeping component 21.

[0101] The length M1 of the top surface of the comb teeth 31 is less than or equal to 3 mm, for example, 1 mm, 2 mm, or 3 mm. If the length M1 of the top surface of the comb teeth 31 is greater than 3 mm, the resistance to the rotation of the cleaning component 21 is greater, which affects the cleaning efficiency of the cleaning component 21.

[0102] In some embodiments, a plurality of first comb teeth 32 are arranged in parallel, and a plurality of second comb teeth 33 are arranged in parallel.

[0103] For example, in the example shown in Figures 3-13, multiple first comb teeth 32 are arranged in parallel from the left end to the right end of the receiving cavity 11, and multiple second comb teeth 33 are arranged in parallel from the left end to the right end of the receiving cavity 11. The multiple first comb teeth 32 and multiple second comb teeth 33 clean the entire cleaning component 21 from left to right, and have high cleaning efficiency.

[0104] In some embodiments, the spacing between adjacent first comb teeth 32 is greater than the thickness of the second comb teeth 33. This results in the comb teeth 31 having higher cleaning efficiency for the cleaning component 21.

[0105] The spacing between adjacent first comb teeth 32 can be constant or variable, and the thickness of the second comb teeth 33 can be constant or variable.

[0106] When the spacing between adjacent first comb teeth 32 is constant and the thickness of the second comb tooth 33 is constant, the spacing between adjacent first comb teeth 32 is greater than the thickness of the second comb tooth 33.

[0107] When the spacing between adjacent first comb teeth 32 varies and the thickness of the second comb teeth 33 varies, for example, in the examples shown in Figures 6, 9, and 12, the thickness T3 of the first tooth tip 311 of the comb tooth 31 is less than the thickness T4 of the second tooth tip 312 of the comb tooth 31. This makes it easier for the comb tooth 31 to enter the cleaning member 21 and reduces the rotational resistance of the cleaning member 21. When the spacing S1 between the top edges of the first tooth tips 311 of adjacent first comb teeth 32 is greater than the thickness T3 of the first tooth tip 311 of the second comb tooth 33, the second comb tooth 33 more easily enters the portion of the cleaning member 21 that passes between adjacent first comb teeth 32, resulting in higher cleaning efficiency.

[0108] It should be noted that the thickness of the comb teeth 31 can be constant along the radial direction of the cleaning component 2, or the thickness T1 of the top surface of the comb teeth 31 can be less than the thickness T2 of the bottom surface of the comb teeth 31. When the thickness T1 of the top surface of the comb teeth 31 is less than the thickness T2 of the bottom surface of the comb teeth 31, the thickness T3 of the first tooth tip 311 of the comb teeth 31 being less than the thickness T4 of the second tooth tip 312 of the comb teeth 31 means that, in a cross-section parallel to the wall of the accommodating cavity 11, the thickness T3 of the first tooth tip 311 of the comb teeth 31 in the cross-section is less than the thickness T4 of the second tooth tip 312 of the comb teeth 31 in the cross-section. The distance S1 between the top edges of the first tooth tips 311 of adjacent first comb teeth 32 being greater than the thickness T3 of the first tooth tip 311 of the second comb teeth 33 means that the distance S1 between the top edges of the first tooth tips 311 of adjacent first comb teeth 32 is greater than the thickness T3 of the top of the first tooth tip 311 of the second comb teeth 33.

[0109] In some embodiments, a dust guide groove 14 is provided on the wall of the accommodating cavity 11, the dust guide groove 14 surrounds the dust collection port 12, the distance L3 between the first end 141 and the second end 142 of the dust guide groove 14 is greater than or equal to 50 mm, and the length L4 of the dust collection port 12 along the axial direction of the cleaning component 2 is greater than or equal to 25 mm and less than or equal to 60 mm.

[0110] For example, in the example shown in FIG3, the dust guide channel 14 has a first end 141 and a second end 142 disposed opposite to each other along the axial direction of the cleaning component 2. In other words, the dust guide channel 14 has a first end 141 and a second end 142 disposed opposite to each other along the longitudinal direction of the receiving cavity 11. In some embodiments, the first end 141 of the dust guide channel 14 is the left end of the dust guide channel 14, and the second end 142 of the dust guide channel 14 is the right end of the dust guide channel 14.

[0111] The distance L3 between the left and right ends of the dust guide groove 14 is greater than or equal to 50 mm, for example, 50 mm, 60 mm, 85 mm, or 100 mm. This allows debris cleaned off the comb teeth 31 by the cleaning component 21 to easily enter the dust guide groove 14.

[0112] In some embodiments, the dust collection port 12 is located in the middle of the dust guide groove 14 along the left-right direction. The length L4 of the dust collection port 12 along the axial direction of the cleaning component 2, i.e., as shown in FIG3, is greater than or equal to 25 mm and less than or equal to 60 mm, for example, 25 mm, 30 mm, 45 mm, 50 mm, or 60 mm. If the length L4 of the dust collection port 12 is less than 25 mm, it is not conducive to larger debris entering the dust collection port 12. If the length L4 of the dust collection port 12 is greater than 60 mm, the airflow generated by the dust collection port 12 is small, which is not conducive to sucking in debris.

[0113] In some implementations, the comb teeth 31 have a first tooth tip 311 and a second tooth tip 312, with the first tooth tip 311 being closer to the dust collection port 12 than the second tooth tip 312, and the first tooth tip 311 of the comb teeth 31 facing the center of the dust collection port 12.

[0114] Specifically, the first tooth tip 311 of each comb tooth 31 is oriented toward the center of the dust collection port 12 relative to the second tooth tip 312 of the comb tooth 31.

[0115] Mounting plate 34 has a center line in the left-right direction, and the center of dust collection port 12 is located in the extension direction of the center line of mounting plate 34.

[0116] Both the first row of comb teeth 31 and the second row of comb teeth 31 include a left side portion and a right side portion divided in the left-right direction, or include a left side portion, a middle portion and a right side portion divided in the left-right direction.

[0117] The plurality of comb teeth 31 on the left side (including the plurality of first comb teeth 32 and the plurality of second comb teeth 33 on the left side) are located to the left of the center line of the mounting plate 34, the plurality of comb teeth 31 on the right side (including the plurality of first comb teeth 32 and the plurality of second comb teeth 33 on the right side) are located to the right of the center line of the mounting plate 34, and the plurality of comb teeth 31 in the middle (including the plurality of first comb teeth 32 and the plurality of second comb teeth 33 in the middle) are located between the plurality of comb teeth 31 on the left side and the plurality of comb teeth 31 on the right side. In some embodiments, the plurality of comb teeth 31 in the middle (including the plurality of first comb teeth 32 and the plurality of second comb teeth 33 in the middle) are located near the center line of the mounting plate 34.

[0118] The comb teeth 31 on the left side are inclined from left to right from their second tooth end 312 to their first tooth end 311, while the comb teeth 31 on the right side are inclined from right to left from their second tooth end 312 to their first tooth end 311. Several comb teeth 31 in the middle section are arranged parallel to the center line of the mounting plate 34. This allows for better guidance of the cleaned debris towards the dust collection port 12.

[0119] In some embodiments, the spacing between adjacent first comb teeth 32 is consistent, the spacing between adjacent second comb teeth 33 is consistent, and the resistance when the cleaning member 21 rotates is small.

[0120] In some embodiments, the spacing between the innermost adjacent first comb teeth 32 is the smallest, and the spacing between the remaining adjacent first comb teeth 32 increases sequentially from the inside to the outside. In other words, the spacing between the two first comb teeth 32 closest to the center line of the mounting plate 34 is the smallest, and the spacing between the remaining adjacent first comb teeth 32 increases sequentially in the direction away from the center line of the mounting plate 34. Furthermore, the spacing between the two first comb teeth 32 located at the center in the left-right direction is the smallest. Among the multiple first comb teeth 32 to the left of the two center first comb teeth 32, the spacing between adjacent first comb teeth 32 increases sequentially from right to left. Among the multiple first comb teeth 32 to the right of the two center first comb teeth 32, the spacing between adjacent first comb teeth 32 increases sequentially from left to right.

[0121] The spacing between the innermost adjacent second comb teeth 33 is the smallest, and the spacing between the remaining adjacent second comb teeth 33 increases sequentially from the inside out. In other words, the spacing between the two second comb teeth 33 closest to the center line of the mounting plate 34 is the smallest, and the spacing between the remaining adjacent second comb teeth 33 increases sequentially in the direction away from the center line of the mounting plate 34. Furthermore, the spacing between the two second comb teeth 33 located in the middle along the left-right direction is the smallest. Among the multiple second comb teeth 33 to the left of the two middle second comb teeth 33, the spacing between adjacent second comb teeth 33 increases sequentially from right to left. Among the multiple second comb teeth 33 to the right of the two middle second comb teeth 33, the spacing between adjacent second comb teeth 33 increases sequentially from left to right.

[0122] This prevents debris from accumulating on the comb teeth at both ends.

[0123] In some embodiments, each first comb tooth 32 includes long comb teeth 321 and short comb teeth 322, which are arranged alternately along the axial direction of the cleaning component 2. The long comb teeth 321 and short comb teeth 322 of each first comb tooth 32 are staggered with the second comb teeth 33 along the axial direction of the cleaning component 2. The long comb tooth 321 includes a first tooth segment 3211 and a second tooth segment 3212. The first tooth segment 3211 and the short comb teeth 322 are arranged side by side along the axial direction of the cleaning component 2, and the second tooth segment 3212 extends obliquely from the first tooth segment 3211 to the space between adjacent second comb teeth 33.

[0124] For example, in the example shown in Figures 14-17, each first comb tooth 32 includes a long comb tooth 321 and a short comb tooth 322. The length of the long comb tooth 321 is greater than the length of the short comb tooth 322. The long comb tooth 321 and the short comb tooth 322 are arranged alternately along the axial direction of the cleaning component 2 (i.e., the left-right direction as shown in Figure 16). The long comb tooth 321 and the short comb tooth 322 are arranged alternately with the second comb tooth 33 in the left-right direction.

[0125] The long comb teeth 321 include a first tooth segment 3211 and a second tooth segment 3212. The first tooth segment 3211 and the short comb teeth 322 are arranged side by side along the axial direction of the cleaning component 2. In some embodiments, both the first tooth segment 3211 and the short comb teeth 322 extend along the circumference of the cleaning component 2 (i.e., the up-down direction as shown in FIG. 16) and are spaced apart along the axial direction of the cleaning component 2. The second tooth segment 3212 extends obliquely from the first tooth segment 3211 to between adjacent second comb teeth 33. As shown in FIG. 14, the second tooth segment 3212 of the long comb tooth 321 located to the left of the center line of the mounting plate 34 extends obliquely from left to right, and the second tooth segment 3212 of the long comb tooth 321 located to the right of the center line of the mounting plate 34 extends obliquely from right to left. Two second tooth segments 3212 are provided between adjacent second comb teeth 33 located in the middle of the left-right direction. In other words, two second tooth segments 3212 are provided between the first second comb tooth 33 on the left and the first second comb tooth 33 on the right of the center line of the mounting plate 34. Each of the remaining adjacent second comb teeth 33 is separated by a second tooth segment 3212. In some embodiments, the first tooth tip 311 of the second comb tooth 33 faces the center of the dust collection port 12.

[0126] The first tooth segment 3211 of the long comb tooth 321 mainly cleans the cleaning component 21, while the second tooth segment 3212 guides the cleaning component 21, causing it to pass over the short comb tooth 322 and the second comb tooth 33 in sequence to be cleaned, thus achieving a good cleaning effect on the cleaning component 21.

[0127] In some embodiments, the cleaning component 2 includes a rotating shaft 22 and a sweeping component 21. The sweeping component 21 includes at least one rubber strip 211 and at least one bristle row 212. The bristle row 212 and the rubber strip 211 are arranged side by side along the circumference of the rotating shaft 22. The distance L5 between the rubber strip 211 and the bristle row 212 is greater than or equal to 1 mm and less than or equal to 5 mm. Along the rotation direction of the cleaning component 2, the rubber strip 211 is located downstream of the bristle row 212.

[0128] As shown in Figures 18 and 19, the cleaning component 2 includes a rotating shaft 22 and a cleaning element 21. The rotating shaft 22 extends in a left-right direction; in other words, the axial direction of the rotating shaft 22 is left-right. The rotating shaft 22 has a first rotating end and a second rotating end arranged opposite to each other along its axial direction. In some embodiments, the left end of the rotating shaft 22 is the first rotating end, and the right end of the rotating shaft 22 is the second rotating end. Both the left and right ends of the rotating shaft 22 can be rotatably supported on the wall of the receiving cavity 11, or one end can be supported on the wall of the receiving cavity 11, and the other end can be suspended. In some embodiments, the left end of the rotating shaft 22 is rotatably supported on the left end of the receiving cavity 11, and the right end of the rotating shaft 22 is rotatably supported on the right end of the receiving cavity 11.

[0129] The cleaning component 21 includes a rubber strip 211 and a bristle row 212. There can be one, two, three or more rubber strips 211 and bristle rows 212. When there are at least two rubber strips 211 and bristle rows 212, the rubber strips 211 and bristle rows 212 are arranged alternately and at intervals along the circumference of the rotating axis.

[0130] As shown in Figure 19, the cleaning component 2 rotates counterclockwise. Along the rotation direction of the cleaning component 2, the rubber strip 211 is located downstream of the bristle row 212. The distance L5 between the bristle row 212 and the rubber strip 211 downstream of it is greater than or equal to 1 mm and less than or equal to 5 mm, for example, 1 mm, 2.5 mm, 3 mm, or 4.5 mm. If the distance L5 between the bristle row 212 and the rubber strip 211 downstream of it is less than 1 mm, the rubber strip 211 affects the deformation of the bristle row 212, reducing the cleaning effect of the bristle row 212 on the surface to be cleaned and the cleaning effect of the comb teeth 31 on the bristle row 212. If the distance L5 between the bristle row 212 and the rubber strip 211 downstream of it is greater than 5 mm, the cleaning effect of the rubber strip 211 and the bristle row 212 is poor.

[0131] In some embodiments, the bristle array 212 includes a first segment 2121 and a second segment 2122, which extend helically around the axial direction of the rotating shaft 22. The helical directions of the first segment 2121 and the second segment 2122 are opposite, and the connection point of the first segment 2121 and the second segment 2122 is located in the middle of the rotating shaft 22. The rubber strip 211 includes a first section 2111 and a second section 2112, which extend helically around the axial direction of the rotating shaft 22. The helical directions of the first section 2111 and the second section 2112 are opposite. The first section 2111 is parallel to the first segment 2121, and the second section 2112 is parallel to the second segment 2122. The connection point of the first section 2111 and the second section 2112 is located in the middle of the rotating shaft 22, and the center of the dust collection port 12 corresponds to the connection point of the first segment 2121 and the second segment 2122.

[0132] As shown in Figure 18, the bristle row 212 is divided into a first segment 2121 and a second segment 2122 along the left and right direction. The first segment 2121 is located to the left of the second segment 2122. The first segment 2121 and the second segment 2122 extend spirally around the axis of the rotating shaft 22, and the spiral directions of the first segment 2121 and the second segment 2122 are opposite, so that the bristle row 212 is V-shaped. The connection point of the first segment 2121 and the second segment 2122 is located in the middle of the rotating shaft 22 along the left and right direction and corresponds to the center of the dust collection port 12.

[0133] The rubber strip 211 is divided into a first section 2111 and a second section 2112 along the left-right direction. The first section 2111 is located to the left of the second section 2112. The first section 2111 and the second section 2112 extend spirally around the axis of the rotating shaft 22. The spiral directions of the first section 2111 and the second section 2112 are opposite. The first section 2111 is parallel to the first segment 2121, and the second section 2112 is parallel to the second segment 2122. The connection between the first section 2111 and the second section 2112 is located in the middle of the rotating shaft 22 along the left-right direction and corresponds to the center of the dust collection port 12.

[0134] During the rotation of the cleaning component 2, the first section 2121 and the second section 2122 with opposite spiral directions, as well as the first section 2111 and the second section 2112 with opposite spiral directions, work together to guide the cleaned debris toward the dust collection port 12 so that it can be sucked in by the dust collection port 12.

[0135] In some embodiments, such as the example shown in FIG18, the included angle α between the first segment 2121 and the second segment 2122 is greater than or equal to 50° and less than or equal to 175°, and the included angle β between the first section 2111 and the second section 2112 is greater than or equal to 50° and less than or equal to 175°. For example, the included angles α and β are both 50°, 80°, 120°, 155°, and 175°.

[0136] When the included angles α and β are less than 50°, excessive debris gets tangled in the middle part of the bristle row 212 along the left-right direction, which is not conducive to the comb teeth 31 cleaning the bristle row 212. When the included angles α and β are greater than 175°, the effect of guiding debris to the dust collection port 12 is poor.

[0137] The bristles of the bristle row 212 can be arranged in a straight line along the radial direction of the rotating shaft 22, so that the bristle row 212 can clean up debris such as hair and fibers on the surface to be cleaned, and also make it easier for the comb teeth 31 to remove debris from the bristle row 212, as shown in Figure 18.

[0138] The bristles of the bristle row 212 can also be arranged radially inclined along the rotating shaft 22. For example, in the example shown in Figure 20, the bristles of the first section 2121 are inclined from the first rotating end of the rotating shaft 22 toward the second rotating end of the rotating shaft 22; in other words, the bristles of the first section 2121 are inclined from left to right. The bristles of the second section 2122 are inclined from the second rotating end of the rotating shaft 22 toward the first rotating end of the rotating shaft 22; in other words, the bristles of the second section 2122 are inclined from right to left. The bristles of the first section 2121 and the second section 2122 guide the debris towards the center, so that the debris can enter the dust collection port 12.

[0139] The angle γ between the bristles of the first segment 2121 and the central axis A of the rotating shaft 22, and the angle θ between the bristles of the second segment 2122 and the central axis A of the rotating shaft 22, are both greater than or equal to 15° and less than or equal to 75°, for example, 15°, 30°, 45°, 60°, and 75°.

[0140] When the included angles γ and θ are less than 15°, the bristle row 212 has a poor cleaning effect on the surface to be cleaned; when the included angles γ and θ are greater than 75°, the debris is more likely to detach from the bristle row 212.

[0141] In some embodiments, within the cross-section of the rotating shaft 22, the included angle ρ between the bristles of the bristle row 212 and the rubber strip 211 is greater than or equal to 1° and less than or equal to 45°.

[0142] As shown in Figures 19 and 20, within the cross-section of the rotating shaft 22, or in other words, within the cross-section of the accommodating cavity 11, the included angle ρ between the bristles of the bristle row 212 and the rubber strip 211 is greater than or equal to 1° and less than or equal to 45°, for example, 1°, 8°, 15°, 30°, or 45°, so that the comb teeth 31 can clean debris off the bristle row 212.

[0143] In some embodiments, within the cross-section of the rotating shaft 22, the interference N between the bristle row 212 and the comb teeth 31 is greater than or equal to 0.5 mm and less than or equal to 7 mm, and the distance M between the rubber strip 211 and the comb teeth 31 is greater than or equal to 0.2 mm and less than or equal to 5 mm.

[0144] As shown in Figures 19 and 20, within the cross-section of the rotating shaft 22, in other words, within the cross-section of the accommodating cavity 11.

[0145] The interference amount N between the bristle row 212 and the comb teeth 31 is greater than or equal to 0.5 mm and less than or equal to 7 mm. In other words, the depth to which the comb teeth 31 insert into the bristle row 212 radially along the rotating shaft 22 is greater than or equal to 0.5 mm and less than or equal to 7 mm, for example, 0.5 mm, 1.5 mm, 5 mm, or 7 mm. If the interference amount N is less than 0.5 mm, the cleaning effect of the comb teeth 31 on the bristle row 212 is poor; if the interference amount N is greater than 7 mm, the rotational resistance of the bristle row 212 is high.

[0146] The distance M between the rubber strip 211 and the comb teeth 31 is greater than or equal to 0.2 mm and less than or equal to 5 mm. The distance M is the radial distance between the rubber strip 211 and the comb teeth 31 along the rotating shaft 22 when the rubber strip 211 passes the comb teeth 31, for example, 0.2 mm, 0.8 mm, 2.5 mm, or 5 mm. If the distance M is less than 0.2 mm, the rubber strip 211 may collide with the comb teeth 31 when the cleaning component 2 rotates, affecting the rotation of the cleaning component 2. If the distance M is greater than 5 mm, the cleaning effect of the rubber strip 211 will be poor.

[0147] It should be noted that the bristles of the bristle bar 212 can be either straight or curved to facilitate cleaning debris from the surface to be cleaned. The rotating shaft 22 is provided with bristle mounting holes for mounting the bristles. The diameter of the mounting holes is greater than or equal to 0.5 mm and less than or equal to 4 mm, the number of bristles in the mounting holes is greater than or equal to 30 and less than or equal to 600, the bristle diameter is greater than or equal to 0.04 mm and less than or equal to 0.2 mm, and the spacing between adjacent mounting holes is greater than or equal to 0.5 mm and less than or equal to 8 mm.
