[0001] This disclosure claims priority to Chinese patent application No. 202422685297.1, filed on November 4, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of cleaning technology, and more specifically, to a cleaning device. Background Technology

[0003] During the cleaning process, cleaning robots or cleaning equipment such as robot vacuums and robot mops are prone to having debris such as hair and fibers entangled on cleaning components such as roller brushes. These debris are not easily sucked into the dust collection components, which affects the cleaning effect. The cleaning components need to be cleaned and replaced frequently and are difficult to clean. Summary of the Invention

[0007] In the cleaning device of this embodiment, the comb teeth are detachably mounted on the wall of the receiving cavity, facilitating disassembly, maintenance, and replacement. Simultaneously, the included angle between the comb teeth and the cleaning component's axial direction is greater than or equal to 65 degrees and less than or equal to 85 degrees. This improves the cleaning effect of the comb teeth on debris entangled on the cleaning component. If the included angle between the comb teeth and the cleaning component's axial direction is less than 65 degrees, the resistance from the comb teeth to the cleaning component is greater, affecting the rotation of the cleaning component, increasing energy consumption, and causing damage to the cleaning component. If the included angle between the comb teeth and the cleaning component's axial direction is greater than 85 degrees, the cleaning component can easily pass through the gaps between adjacent comb teeth when passing over them, affecting the cleaning effect of the comb teeth on the cleaning component.

[0041] 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.

[0042] In related technologies, cleaning teeth have been proposed to remove hair and other debris tangled on the cleaning components during the cleaning process. However, the cleaning teeth in these technologies have the problem of poor cleaning effect, and there is a need for improvement.

[0043] The inventors of this disclosure, through research, discovered and recognized that in related technologies, cleaning robots or cleaning devices such as robotic vacuum cleaners and robotic mops typically incorporate comb teeth within the main brush mounting cavity to remove hair and other debris entangled on the main brush. While these comb teeth can clean the main brush to some extent, their cleaning effect is poor in actual use. The main brush needs to be removed for manual cleaning, resulting in frequent disassembly and reassembly. Furthermore, the comb teeth wear out, making replacement and maintenance inconvenient. The inclusion of comb teeth also increases the energy consumption of the cleaning device. Therefore, based on the aforementioned research, the inventors of this disclosure propose corresponding improvement measures targeting at least one or more aspects, including improving the cleaning effect of hair, fibers, and other debris entangled on the main brush, reducing the frequency of main brush replacement, improving the convenience of comb tooth replacement and maintenance, improving usability and cleaning effect, and reducing energy consumption.

[0044] The cleaning apparatus of embodiments of the present disclosure is described below with reference to the accompanying drawings.

[0045] The cleaning equipment in this disclosure can be, but is not limited to, a sweeping robot and a sweeping and mopping robot.

[0046] As shown in Figures 1-8, the cleaning device of this embodiment includes a body 1, a cleaning component 2, and a comb component 3.

[0047] The body 1 has a receiving cavity 11, and the receiving cavity 11 has a dust collection port 12. As shown in Figures 2 and 3, the receiving cavity 11 has a longitudinal direction A, such as the left-right direction in Figures 2 and 3. It can be understood that the receiving cavity 11 has an opening on the bottom surface of the body 1, and 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 2 and 3, in this example, the opening of the receiving cavity 11 is generally rectangular, and the long side of the rectangle extends along the longitudinal direction A.

[0048] A cleaning component 2 is rotatably disposed within a receiving cavity 11 about its central axis, and the cleaning component 2 has a cleaning member 21. In some embodiments, as shown in FIG2, the cleaning component 2 is disposed within the receiving cavity 11 and extends along a longitudinal direction A, the central axis of the cleaning component 2 being parallel to the longitudinal direction A; in other words, the axial direction of the cleaning component 2 is aligned with the longitudinal direction A. In the example shown in FIG2, the central axis of the cleaning component 2 extends in a left-right direction. In embodiments of this disclosure, the central axis of the cleaning component, the axial direction of the cleaning component, and the longitudinal direction can all be referred to by A.

[0049] In some embodiments, the cleaning component 2 may be a main brush, and the sweeping component 21 may be bristles and / or rubber strips disposed 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.

[0050] The comb component 3 includes a mounting plate 31 and a plurality of comb teeth 32. The comb teeth 32 are used to clean the cleaning component 21, such as removing debris such as hair and fibers entangled on the cleaning component 21. The mounting plate 31 is detachably mounted on the wall of the receiving cavity 11. The plurality of comb teeth 32 are disposed on the mounting plate 31 and arranged along the axial direction of the cleaning component 2 (i.e., the longitudinal direction A of the receiving cavity, such as the left and right direction in Figures 2 and 3). The included angle α between the comb teeth 32 and the axial direction of the cleaning component 2 is greater than or equal to 65 degrees and less than or equal to 85 degrees.

[0051] The mounting plate 31 is detachably mounted on the wall of the accommodating cavity 11, and the comb teeth 32 are disposed on the surface of the mounting plate 31. In some embodiments, the mounting plate 31 is detachably mounted on the wall of the accommodating cavity 11 by means of a snap-fit ​​structure, thereby further improving the ease of assembly and disassembly of the comb teeth component. When the mounting plate 31 is mounted on the wall of the accommodating cavity 11, the comb teeth 32 protrude relative to the wall surface of the accommodating cavity 11. When the cleaning component 2 rotates, the comb teeth 32 can contact the cleaning component 21, that is, the cleaning component 21 sweeps past the comb teeth 32, thereby cleaning the cleaning component 21, that is, cleaning debris such as hair and fibers attached to or entangled on the cleaning component 21.

[0052] As shown in Figures 2-5, multiple comb teeth 32 are arranged along the longitudinal direction A on the mounting plate 31. The comb teeth 32 extend obliquely relative to the axial direction of the cleaning component 2 (i.e., the longitudinal direction A of the accommodating cavity), and the included angle α between the comb teeth 32 and the axial direction of the cleaning component 2 is greater than or equal to 65 degrees and less than or equal to 85 degrees. In some embodiments, as shown in Figure 5, in the planar projection, the included angle α between the comb teeth 32 and the left-right direction is greater than or equal to 65 degrees and less than or equal to 85 degrees. In some embodiments, the included angle α is approximately 70 degrees.

[0053] In this embodiment of the disclosure, the "comb teeth" are elongated convex strips. In some embodiments, the length L of the comb teeth 32 can be more than 5 times its width W. In some embodiments, the length L of the comb teeth 32 can be more than 10 times its width W.

[0054] The cleaning device of this disclosure has a comb tooth component detachably mounted on the wall of the receiving cavity, making it easy to disassemble, maintain, and replace. Simultaneously, the included angle between the comb teeth and the cleaning component's axis is greater than or equal to 65 degrees and less than or equal to 85 degrees. This prevents the cleaning component from easily passing through the gaps between adjacent comb teeth, improving the cleaning effect of the comb teeth on debris entangled on the cleaning component. Furthermore, the comb teeth do not generate excessive resistance to the cleaning component, reducing damage. The cleaning component rotates smoothly, resulting in low energy consumption.

[0055] The inventors discovered through research that if the angle α between the comb teeth and the cleaning component's axis is less than 65 degrees, the comb teeth exert greater resistance on the cleaning component. If the angle α between the comb teeth and the cleaning component's axis is greater than 85 degrees, the cleaning component easily passes through the gaps between adjacent comb teeth when it sweeps over the comb teeth, affecting the comb teeth's cleaning effect on the cleaning component.

[0056] Therefore, the cleaning device of this embodiment is easy to disassemble and maintain, the comb teeth have a good cleaning effect on the cleaning parts, and the cleaning parts do not need to be frequently disassembled and manually cleaned.

[0057] In some embodiments, the wall of the accommodating cavity 11 is provided with a mounting groove 13. The wall of the accommodating cavity 11 and the mounting groove 13 can be arc-shaped structures. The mounting plate 31 can be an arc-shaped plate adapted to the wall of the accommodating cavity 11 and the mounting groove 13, as shown in FIG6. The mounting plate 31 is detachably installed in the mounting groove 13. In some embodiments, the axial direction of the arc-shaped wall of the accommodating cavity 11, the mounting groove 13 and the mounting plate 31 is aligned with the axial direction of the cleaning component 2, i.e., the longitudinal direction A.

[0058] The mounting plate 31 is detachably installed in the mounting groove 13. In some embodiments, after the mounting plate 31 is installed in the mounting groove 13, the plate surface of the mounting plate 31 with comb teeth 32 is flush with the wall surface of the receiving cavity 11, and the comb teeth 32 protrude from the wall surface of the receiving cavity 11, thereby ensuring that the comb teeth 32 contact the cleaning member 21, while avoiding the mounting plate 31 contacting the cleaning member 21 and blocking the cleaning member 21.

[0059] In some embodiments, the mounting plate 31 is snapped into the mounting groove 13 by a snap-fit ​​structure. As shown in FIG6, the snap-fit ​​structure includes a matching groove 313 and a protrusion (not shown). The groove 313 is located at the rear end of the mounting plate 31, and the protrusion is located on the groove wall of the mounting groove 13. When the mounting plate 31 is fitted into the mounting groove 13, the protrusion is fitted into the groove 313, so as to facilitate the quick installation and removal of the mounting plate and facilitate the processing of the mounting plate.

[0060] In some embodiments, the comb teeth 32 and the mounting plate 31 are integrally injection molded, thereby reducing costs and facilitating the processing of the comb teeth components.

[0061] As shown in Figures 4-6, in some embodiments, the mounting plate 31 has a first side surface 311 and a second side surface 312 extending axially along the cleaning member 2, i.e., the first side surface 311 and the second side surface 312 extend longitudinally A and are opposite to each other in the circumferential direction of the receiving cavity 11. The comb teeth 32 have a first tooth tip 321 and a second tooth tip 322 opposite to each other in the extending direction of the comb teeth. The first tooth tip 321 of the comb teeth 32 is adjacent to the first side surface 311 of the mounting plate 31, and the second tooth tip 322 of the comb teeth 32 is away from the first side surface 311 of the mounting plate 31. The end face of the first tooth tip 321 of the comb teeth 32 may be flush with the first side surface 311 of the mounting plate 31, i.e., the first tooth tip 321 of the comb teeth 32 does not extend beyond the first side surface 311 of the mounting plate 31. In some embodiments, as shown in Figure 6, the end face of the first tooth tip 321 of the comb teeth 32 extends outward beyond the first side surface 311 of the mounting plate 31. Here, "outward" means that the first tooth tip 321 of the comb tooth 32 extends beyond the first side surface 311 of the mounting plate 31 in a direction away from the first side surface 311 (e.g., a direction orthogonal to the axial direction of the cleaning component, the left-right direction in FIG. 6), as shown in FIG. 6. It can be understood that in the example shown in FIG. 6, the end face of the first tooth tip 321 of the comb tooth 32 is aligned with the first side surface 311 of the mounting plate 31 in the inclined direction.

[0062] In some embodiments, the mounting plate 31 and the dust collection port 12 are disposed adjacent to each other circumferentially along the receiving cavity 11, and the mounting plate 31 is located downstream of the dust collection port 12 in the rotation direction of the cleaning component 2. The first side surface 311 of the mounting plate 31 is adjacent to the dust collection port 12, and the second side surface 312 of the mounting plate 31 is away from the dust collection port 12. The first tooth tip 321 of the comb teeth 32 is adjacent to the first side surface 311 of the mounting plate 31, and the second tooth tip 322 of the comb teeth 32 is away from the first side surface 311 of the mounting plate 31.

[0063] The dust collection port 12 has a first side 121 and a second side 122 extending along the axial direction of the cleaning component. The first side 121 and the second side 122 are opposite each other in the circumferential direction of the receiving cavity 11. The first side 121 is closer to the mounting plate 31 than the second side 122. In other words, the first side 121 of the dust collection port 12 is adjacent to the first side 311 of the mounting plate 31.

[0064] In the axial direction of the cleaning component 2, the outermost comb tooth 32 is adjacent to the first end 123 of the dust collection port 12 (the left end of the dust collection port 12 as shown in Figure 4), and the outermost comb tooth 32 is adjacent to the second end 124 of the dust collection port 12 (the right end of the dust collection port 12 as shown in Figure 4).

[0065] The distance between the first side surface 311 of the mounting plate 31 and the first side edge 121 of the dust collection port 12 is greater than zero and less than or equal to 10 mm. In some embodiments, the distance between the first side surface 311 of the mounting plate 31 and the first side edge 121 of the dust collection port 12 is 3 mm, 5 mm, 8 mm, and 10 mm. As shown in FIG4, this distance is the distance between the first side surface 311 and the first side edge 121 in the vertical direction in FIG4. Since the walls of the mounting plate 31 and the accommodating cavity 11 are arc-shaped, this distance can also be referred to as the circumferential distance between the first side surface 311 and the first side edge 121 in the accommodating cavity and the mounting plate.

[0066] 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 32 and first contacts the first tooth end 321 of the comb teeth 32. The cleaning component 21 sweeps over the comb teeth 32, so that the comb teeth 32 cleans the debris wrapped around the cleaning component 21 from the cleaning component 21. The cleaned debris is sucked into the dust collection port 12.

[0067] The distance between the first side 311 of the mounting plate 31 and the first side 121 of the dust collection port 12 is greater than zero and less than or equal to 10 mm, which indirectly limits the distance between the first tooth end 321 and the first side 121 of the dust collection port 12. As a result, the debris cleaned by the comb teeth 32 can more easily enter the dust collection port 12. If the distance between the first side 311 of the mounting plate 31 and the first side 121 of the dust collection port 12 is less than zero, the mounting plate 31 extending into the dust collection port 12 will affect the airflow entering the dust collection port 12, and the wind resistance will increase. If the distance between the first side 311 of the mounting plate 31 and the first side 121 of the dust collection port 12 is greater than 10 mm, the cleaned debris will not easily enter the dust collection port, affecting the cleaning effect.

[0068] As shown in Figures 4 and 5, along the axial direction of the cleaning component 2, i.e., along the left-right direction in Figures 4 and 5, the leftmost comb tooth is adjacent to the left end of the dust collection port 12. "Adjacent" means that the leftmost comb tooth can be located to the right or left of the left end of the dust collection port 12, but they are close to each other. The rightmost comb tooth 32 is adjacent to the right end of the dust collection port 12. Similarly, the rightmost comb tooth can be located to the right or left of the right end of the dust collection port 12. That is, the comb teeth correspond to the dust collection port, so that debris such as hair cleaned by the comb teeth 32 is more easily guided towards the dust collection port 12, facilitating the suction of debris into the dust collection port 12 and preventing the cleaned debris from accumulating at both ends of the receiving cavity 11.

[0069] In some embodiments, the mounting plate 31 has an arc-shaped structure, that is, the mounting plate 31 is an arc-shaped plate, and the comb teeth 32 include a first set of comb teeth and a second set of comb teeth. The first set of comb teeth and the second set of comb teeth are located on both sides of the central arc B of the mounting plate 31. The central arc B is the center line of the mounting plate 31 that is orthogonal to the axis of the cleaning component 2. The central arc line can also be called the dividing line between the first set of comb teeth and the second set of comb teeth.

[0070] As shown in Figure 5, the first group of comb teeth includes a plurality of first comb teeth 32A that are parallel to each other, and the second group of comb teeth includes a plurality of second comb teeth 32B that are parallel to each other. The first tooth tip 321 of the first comb tooth 32A is closer to the center arc line B of the mounting plate 31 than the second tooth tip 322 of the first comb tooth 32A. The first tooth tip 321 of the second comb tooth 32B is closer to the center arc line B of the mounting plate 31 than the second tooth tip 322 of the second comb tooth 32B.

[0071] Multiple comb teeth 32 are arranged in the left-right direction and divided into a first group of comb teeth and a second group of comb teeth. The first group of comb teeth is located to the left of the central arc B of the mounting plate 31, and the second group of comb teeth is located to the right of the central arc B of the mounting plate 31.

[0072] Both the first and second groups of comb teeth include multiple comb teeth 32. The comb teeth in the first group of comb teeth are called first comb teeth 32A, and the comb teeth 32 in the second group of comb teeth are called second comb teeth 32B. The multiple first comb teeth 32A are arranged in parallel with each other, and the multiple second comb teeth 32B are arranged in parallel with each other.

[0073] As shown in Figure 4, the first tooth tip 321 of the first comb tooth 32A is closer to the center arc line B of the mounting plate 31 than the second tooth tip 322 of the first comb tooth 32A. In other words, the first comb tooth 32A is inclined downward from left to right. The first tooth tip 321 of the second comb tooth 32B is closer to the center arc line B of the mounting plate 31 than the second tooth tip 322 of the second comb tooth 32B. In other words, the second comb tooth 32B is inclined downward from right to left.

[0074] The tilting direction of the first comb tooth 32A and the second comb tooth 32B is set in such a way that the cleaned debris can be better guided toward the dust collection port 12 so that it can be sucked away by the dust collection port, and the cleaned debris can be prevented from accumulating at both ends of the receiving cavity.

[0075] In some embodiments, the first tooth tip 321 of the innermost first comb tooth 32A and the first tooth tip 321 of the innermost second comb tooth 32B are connected to each other to form a V-shape. The distance S between the tip of the V-shape and the first side surface 311 of the mounting plate 31 is 1.5-3.5 mm. Along the rotation direction of the cleaning component 2, the tip of the V-shape faces the dust collection port 12.

[0076] The rightmost first comb tooth and the leftmost second comb tooth form a V-shape, which can prevent the cleaning part in the middle from passing through the gap between the rightmost first comb tooth and the leftmost second comb tooth.

[0077] The distance S between the V-shaped tip and the first side surface 311 of the mounting plate 31 (i.e., the distance between the V-shaped tip and the upper edge of the first side surface 311) can be 1.5 mm to 3.5 mm. In some embodiments, the distance S between the V-shaped tip and the first side surface 311 of the mounting plate 31 is 1.5 mm, 2.0 mm, 2.5 mm, or 3.5 mm. The upper edge of the end face of the first tooth tip 321 of the remaining comb teeth 32 is flush with or extends outward from the first side surface 311 (upper edge of the side surface) of the mounting plate 31. If the distance S is less than 1.5 mm, the first and second comb teeth forming the V-shape will create greater resistance to the cleaning component, affecting the rotation of the cleaning component; if the distance S is greater than 3.5 mm, the cleaning effect will be poor.

[0078] In some embodiments, the first set of comb teeth and the second set of comb teeth are symmetrical with respect to the center line of the V-shape, which can be the center arc B of the mounting plate. As shown in FIG5, the plurality of first comb teeth 32A of the first set of comb teeth and the plurality of second comb teeth 32B of the second set of comb teeth are symmetrical with respect to the center line B of the V-shape. In other words, the plurality of first comb teeth 32A of the first set of comb teeth and the plurality of second comb teeth 32B of the second set of comb teeth correspond one-to-one with the center arc B of the mounting plate 31 and are symmetrical to each other, thereby better guiding the cleaned debris toward the dust collection port and avoiding the accumulation of cleaned debris at both ends of the receiving cavity.

[0079] In some embodiments, within a cross-section of the mounting plate 31 parallel to the axial direction of the cleaning component 2, the height H of a plurality of comb teeth 32 gradually decreases from the central arc of the mounting plate 31 toward both ends of the mounting plate 31. In some embodiments, the plurality of comb teeth 32 have at least two different heights H, and the comb teeth 32 with different heights H are arranged alternately along the axial direction of the cleaning component 2.

[0080] As shown in Figure 7, within a cross-section of the mounting plate 31 parallel to the axial direction of the cleaning component 2, the heights of the multiple comb teeth 32 can be the same, or they can gradually decrease from the center arc of the mounting plate 31 towards the left and right ends of the mounting plate 31. In other words, the heights of the multiple first comb teeth 32A can be the same, or they can gradually decrease from right to left; the heights of the multiple second comb teeth 32B can be the same, or they can gradually decrease from left to right. Here, "the height of multiple comb teeth within the cross-section" refers to the height of multiple comb teeth at the same position when the comb teeth vary along the length direction, i.e., a single comb tooth has multiple height values. Of course, when the height of a single comb tooth remains constant along the length direction, each comb tooth has a single height. Here, the height of the comb tooth refers to the vertical dimension of the highest point of the comb tooth within the cross-section shown in Figure 7. In this disclosure, the height of the comb tooth can also be characterized by the thickness T of the comb tooth.

[0081] Within the cross-section, the multiple comb teeth 32 may also have at least two different heights, and the comb teeth 32 of different heights are arranged alternately along the axial direction of the cleaning component 2. In some embodiments, there may be 10 first comb teeth 32A, arranged from left to right, with the first to third comb teeth having the same height and being the lowest, the fourth comb tooth having a height greater than the first to third comb teeth, the fifth to seventh comb teeth having the same height and being greater than the fourth comb tooth, the ninth to tenth comb teeth having the same height and being equal to the fifth to seventh comb teeth, and the eighth comb tooth having a height greater than the fourth comb tooth but less than the ninth to tenth comb teeth. The second comb teeth 32B may be symmetrically arranged with the first comb teeth 32A. In some embodiments, the comb teeth of different heights may be arranged in other alternating ways.

[0082] The comb teeth of different heights are arranged alternately to reach different depths of the cleaning components, further improving the cleaning effect and reducing resistance to the cleaning components.

[0083] In some embodiments, the height of the comb teeth 32 decreases from the first tooth tip 321 toward the second tooth tip 322 of the comb teeth 32. This decrease can be gradual or stepped. In some embodiments, the height of the first tooth tip 321 of the comb teeth 32 is greater than the height of the rest of the comb teeth 32, meaning the first tooth tip 321 has the highest height, as shown in FIG6. In other words, the top surface portion of the first tooth tip 321 is further away from the mounting plate 31 than the top surface portion of the rest of the comb teeth 32. When the mounting plate and the receiving cavity are arc-shaped, the height H of the comb teeth 32 can be the radial dimension of the comb teeth 32 along the receiving cavity 11.

[0084] In some embodiments, the height of the first tooth end 321 of the comb tooth 32 is greater than the height of the second tooth end 322 of the comb tooth 32.

[0085] In some embodiments, the first tooth ends 321 of the plurality of comb teeth 32 have at least two different heights and the second tooth ends 322 of the plurality of comb teeth 32 have at least two different heights. The plurality of comb teeth 32 with different heights of the first tooth ends 321 are arranged alternately, and the plurality of comb teeth 32 with different heights of the second tooth ends 322 are arranged alternately. The plurality of comb teeth 32 extend into the cleaning member 21 in at least two sizes to clean debris that penetrates to different depths into the cleaning member 21, thereby further improving the cleaning effect.

[0086] In some embodiments, the two side surfaces 302 of the comb teeth 32 are parallel to each other and inclined relative to the mounting plate 31, wherein the top edge 3021 of the side surface 302 of the comb teeth 32 is further away from the central arc than the bottom edge 3022 of the side surface 302. More specifically, as shown in FIG7, the first comb tooth 32A is inclined to the left and the second comb tooth 32B is inclined to the right.

[0087] As shown in Figure 7, the two opposite sides of the comb teeth 32 are parallel to each other and inclined relative to the mounting plate 31. In other words, the left and right sides of the comb teeth 32 are not orthogonal to the mounting plate 31. In some embodiments, the included angle β between the left and right sides of the comb teeth 32 and the mounting plate 31 is not equal to 90°.

[0088] The side surface 302 of the comb tooth 32 has a top edge 3021 and a bottom edge 3022, wherein the top edge 3021 is the intersection of the side surface 302 and the top surface 301 of the comb tooth 32, and the bottom edge 3022 is the intersection of the side surface 302 and the mounting plate 31. The top edge 3021 of the side surface 302 is farther away from the center arc B of the mounting plate 31 than the bottom edge 3022. In other words, the side surface 302 of the first comb tooth 32A is inclined from left to right in the direction toward the mounting plate 31, and the side surface 302 of the second comb tooth 32B is inclined from right to left in the direction toward the mounting plate 31.

[0089] The inclined direction of the side 302 of the first comb tooth 32A and the inclined direction of the side 302 of the second comb tooth 32B can guide the cleaned debris toward the center of the mounting plate 31, thereby guiding it to the dust collection port 12.

[0090] In some embodiments, the width W of the first tooth end 321 of the comb tooth 32 is smaller than the width W of the rest of the comb tooth 32, and the top surface 301 of the comb tooth 32 is arc-transitioned with the end face of the second tooth end 322 of the comb tooth 32 and the two side surfaces 302 of the comb tooth 32.

[0091] As shown in Figure 5, the width W of the first tooth tip 321 of the comb tooth 32 is smaller than the width W of the rest of the comb tooth 32. In some embodiments, the width of the first tooth tip 321 of the comb tooth 32 is reduced compared to the width of the rest of the comb tooth, thus forming a pointed tip. This makes it easier for the comb tooth 32 to enter the cleaning member 21.

[0092] As shown in Figure 6, the top surface 301 of the comb tooth 32 transitions to the end face of the second tooth end 322 with a rounded arc, and the top surface 301 of the comb tooth 32 also transitions to the side surfaces 302 on the left and right sides with a rounded arc, thereby reducing the resistance of the comb tooth 32 to the cleaning component 21.

[0093] In some embodiments, the spacing P between adjacent comb teeth 32 gradually increases from the center arc B of the mounting plate 31 toward both ends of the mounting plate 31. In some embodiments, adjacent comb teeth 32 have at least two different spacings P, and the different spacings are alternately arranged along the axial direction of the cleaning member 2.

[0094] As shown in Figure 5, the spacing P between adjacent comb teeth 32 gradually increases from the center arc of the mounting plate 31 toward the left and right ends of the mounting plate 31. In other words, from the rightmost first comb tooth 32A to the leftmost first comb tooth 32A, the spacing P between adjacent first comb teeth 32A gradually increases, and from the leftmost second comb tooth 32B to the rightmost second comb tooth 32B, the spacing P between adjacent second comb teeth 32B gradually increases.

[0095] In some embodiments, adjacent comb teeth 32 have at least two different spacings P, and the different spacings are alternately arranged along the axial direction of the cleaning component 2. In some embodiments, the spacing includes a first spacing and a second spacing, the first spacing being greater than the second spacing, and a plurality of first spacings and a plurality of second spacings are alternately arranged in the left-right direction to reduce the resistance of the comb teeth 32 to the cleaning component 21.

[0096] In some embodiments, the maximum spacing between adjacent comb teeth 32 is greater than or equal to 1.5 mm and less than or equal to 3 mm.

[0097] As shown in Figure 5, except for the rightmost first comb tooth 32A and the leftmost second comb tooth 32B forming the V-shape, the maximum spacing P between the remaining adjacent comb teeth 32 is greater than or equal to 1.5 mm and less than or equal to 3 mm. In some embodiments, the spacing is 1.5 mm, 1.8 mm, 2.3 mm, or 3 mm.

[0098] If the spacing P is greater than 3 mm, the cleaning component 21 and debris can easily pass between two adjacent comb teeth 32, thus affecting the cleaning effect on the cleaning component 21. If the spacing P is less than 1.5 mm, it will generate greater resistance to the rotation of the cleaning component 21, and will also affect the cleaning effect on the cleaning component 21.

[0099] In some embodiments, the width W of the widest portion of the comb tooth 32 is greater than or equal to 1 mm and less than or equal to 2 mm, the length L of the comb tooth 32 is greater than or equal to 10 mm and less than or equal to 20 mm, the height H of the highest portion of the comb tooth 32 is greater than or equal to 2.5 mm and less than or equal to 5 mm, and the height of the lowest portion of the comb tooth 32 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0100] As shown in Figure 5, the width W of the widest portion of the comb teeth 32 is greater than or equal to 1 mm and less than or equal to 2 mm. In some embodiments, the width W of the widest portion of the comb teeth 32 is 1 mm, 1.2 mm, 1.6 mm, or 2 mm.

[0101] The length L of the comb teeth 32 is greater than or equal to 10 mm and less than or equal to 20 mm. In some embodiments, the length L of the comb teeth 32 is 10 mm, 15 mm, 18 mm, or 20 mm.

[0102] The height H of the highest portion of the comb teeth 32 is greater than or equal to 2.5 mm and less than or equal to 5 mm. In some embodiments, the height H of the highest portion of the comb teeth 32 is 2.5 mm, 2.8 mm, 3.5 mm, or 5 mm.

[0103] The height H of the lowest portion of the comb teeth 32 is greater than or equal to 1 mm and less than or equal to 2 mm. In some embodiments, the height H of the lowest portion of the comb teeth 32 is 1 mm, 1.5 mm, 1.8 mm, or 2 mm.

[0104] If the width W, length L, and height H of the comb teeth 32 are too large, it will increase the resistance and affect the rotation of the sweeping part 21; if they are too small, it will reduce the cleaning effect on the sweeping part 21.

[0105] In some embodiments, the cross-section of the accommodating cavity 11 is arc-shaped, the dust collection port 12 is a rounded rectangle or a rounded trapezoid, the diameter of the accommodating cavity 11 is greater than or equal to 40 mm and less than or equal to 60 mm, the length of the dust collection port 12 is greater than or equal to 50 mm and less than or equal to 80 mm, and the width of the dust collection port 12 is greater than or equal to 15 mm and less than or equal to 25 mm.

[0106] As shown in Figures 3 and 4, in some embodiments, the cross-section of the accommodating cavity 11 is semi-circular, and the diameter of the accommodating cavity 11 is greater than or equal to 40 mm and less than or equal to 60 mm. In some embodiments, the diameter of the accommodating cavity 11 is 40 mm, 45 mm, 47 mm, 50 mm, 52 mm, 55 mm, 58 mm, or 60 mm.

[0107] The dust collection port 12 can be a rounded rectangle or a rounded trapezoid, and its length D in the left-right direction is greater than or equal to 50 mm and less than or equal to 80 mm. When the dust collection port 12 is a rounded trapezoid, the length D of the dust collection port 12 varies, and the distance (length) between the first side 121 and the second side 122 of the dust collection port 12 is greater than or equal to 50 mm and less than or equal to 80 mm. In some embodiments, the length D of the dust collection port 12 decreases in the direction toward the comb tooth component 3, that is, the length of the first side 121 is less than the length of the second side 122. In some embodiments, the length of the first side 121 is 50 mm and the length of the second side 122 is 70 mm. In some embodiments, the length of the first side 121 is 60 mm and the length of the second side 122 is 80 mm.

[0108] Along the circumference of the accommodating cavity 11, the width K of the dust collection port 12 is greater than or equal to 15 mm and less than or equal to 25 mm. In some embodiments, the width K of the dust collection port 12 is 15 mm, 18 mm, 22 mm, or 25 mm.

[0109] The dimensions of the accommodating cavity 11 and the dust collection port 12 are matched to improve the cleaning effect of the surface to be cleaned, as well as the suction power and dust collection effect of the dust collection port 12.

[0110] In some embodiments, the cleaning component 2 includes a rotating shaft 22, a baffle 23, and a sweeping component 21. The baffle 23 is respectively installed on a first rotating end and a second rotating end of the rotating shaft 22. At least a portion of the outer peripheral surface of the baffle 23 is provided with a blocking element. The sweeping component 21 includes at least one bristle row. The bristle row includes a first segment 211 and a second segment 212, which extend spirally around the axial direction of the rotating shaft 22. The spiral directions of the first segment 211 and the second segment 212 are opposite. The connection point of the first segment 211 and the second segment 212 is located in the middle of the rotating shaft 22. The positions of the dust collection port 12, the mounting plate 31, and the connection point of the first segment 211 and the second segment 212 correspond to each other.

[0111] As shown in Figure 8, the cleaning component 2 includes a rotating shaft 22, a baffle 23, and a cleaning component 21. The rotating shaft 22 extends in the left-right direction and has a left end and a right end opposite to each other in the left-right direction. 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. The left end or the right end of the rotating shaft 22 is connected to a driver in the body 1. The driver can be, but is not limited to, a rotating motor.

[0112] Both ends of the rotating shaft 22 are provided with coaxial baffles 23. All or part of the outer peripheral surface of the baffle 23 is provided with a blocking element. The blocking element can be, but is not limited to, lint, used to block the debris swept down to the left and right ends of the rotating shaft 22 and the machine body 1.

[0113] There can be one, two, three or more bristle rows. When there are multiple bristle rows, they are arranged at intervals along the circumference of the rotation axis 22.

[0114] The bristle array is divided into a first section 211 and a second section 212 along the left-right direction. The first section 211 is located to the left of the second section 212. The first section 211 and the second section 212 extend spirally around the axis of the rotating shaft 22, and the spiral directions of the first section 211 and the second section 212 are opposite, so that the bristle array is V-shaped. The connection point of the first section 211 and the second section 212 is located in the middle of the rotating shaft 22 along the left-right direction, and corresponds to the position of the dust collection port 12 and the position of the mounting plate 31.

[0115] During the rotation of the cleaning component 2, the first segment 211 sweeps over the first comb tooth group, and the second segment 212 sweeps over the second comb tooth group. The first segment 211 and the second segment 212, which are spiraling in opposite directions, guide the cleaned debris toward the dust collection port 12 so that it can be sucked into the dust collection port 12. At the same time, debris such as hair cleaned by the comb teeth is guided toward the dust collection port 12 to improve the cleaning effect.

[0116] In some embodiments, the bristles extend helically around the axial direction of the rotating shaft 22. The first rotating end of the rotating shaft 22 is rotatably supported on the body 1, and the second rotating end of the rotating shaft 22 is suspended. The positions of the dust collection port 12 and the mounting plate 31 are adjacent to the second rotating end of the rotating shaft 22. Specifically, the positions of the dust collection port 12 and the mounting plate 31 are adjacent to the second rotating end of the rotating shaft 22. The bristles guide the cleaned debris toward the second rotating end of the rotating shaft 22 so that it can be sucked into the dust collection port 12, thereby improving the cleaning effect.

[0117] The first rotating end of the rotating shaft 22 is provided with a coaxial baffle 23. All or part of the outer peripheral surface of the baffle 23 is provided with a blocking element. The blocking element can be, but is not limited to, lint, and is used to block the debris swept down to the space between the first rotating end of the rotating shaft 22 and the machine body 1.

[0118] It is understood that the cleaning component is not limited to bristle rows; in other embodiments, the cleaning component may also include an adhesive strip. In some embodiments, the adhesive strip is arranged side by side and parallel to the bristle rows.
