DETAILED DESCRIPTION

[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0041] The inventor of the present application has found and realized through research that, in the related art, cleaning robots or cleaning equipment such as a sweeping robot and a sweeping and mopping robot, in order to clean hair and other sundries wound on a main brush, a comb tooth is usually arranged in a main brush mounting cavity, the comb tooth can clean the main brush to a certain extent, but there is a problem of poor cleaning effect in actual use, the main brush needs to be manually cleaned after being disassembled, disassembly and assembly are frequent, the comb tooth is inconvenient to replace and maintain after being worn, and the arrangement of the comb tooth also affects the energy consumption of the cleaning equipment. Therefore, on the basis of the above research, the inventor of the present application proposes corresponding improvement measures aiming at at least one or several aspects of improving the cleaning effect of hair, fibers and other sundries wound on the main brush, reducing the replacement frequency of the main brush, improving the convenience of replacing and maintaining the comb tooth, improving the usability and cleaning effect, and reducing the energy consumption.

[0042] The cleaning equipment according to the embodiments of the present application is described below with reference to the drawings.

[0043] The cleaning equipment is preferably but not limited to a sweeping robot and a sweeping and mopping robot.

[0044] As Figures 1-8 shown, the cleaning equipment includes a body 1, a cleaning component 2 and a comb component 3.

[0045] The body 1 has a receiving cavity 11, and the receiving cavity 11 has a dust collecting opening 12. As Figure 2 and Figure 3 shown, the receiving cavity 11 has a longitudinal direction A, for example, a left-right direction in Figure 2 and Figure 3 It can be understood that the receiving cavity 11 is open at the bottom surface of the body 1, and the cleaning component 2 sweeps the dirt on the surface to be cleaned, such as the ground, into the receiving cavity 11 through the opening. As Figure 2 and Figure 3 shown, 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.

[0046] The cleaning component 2 is rotatably arranged in the receiving cavity 11 about a central axis, and the cleaning component 2 has a sweeping part 21. For example, as Figure 2 shown, the cleaning component 2 is arranged in the receiving cavity 11 and extends along the longitudinal direction A, the central axis of the cleaning component 2 is parallel to the longitudinal direction A, in other words, the axial direction of the cleaning component 2 is consistent with the longitudinal direction A, and in the example shown, the central axis of the cleaning component 2 extends along the left-right direction. In the embodiments of the present application, the central axis of the cleaning component, the axial direction of the cleaning component and the longitudinal direction can all be represented by A. Figure 2

[0047] The cleaning component 2 may, for example, be a main brush, and the sweeping part 21 may, for example, be bristles and / or rubber strips arranged on the rotating shaft of the main brush, and the sweeping part 21 is used to contact the surface to be cleaned, such as the ground, to clean the surface to be cleaned.

[0048] The comb component 3 includes a mounting plate 31 and a plurality of combs 32, and the combs 32 are used to clean the sweeping part 21, such as to clean the sundries such as hair and fibers that are wound on the sweeping part 21. The mounting plate 31 is detachably mounted on the wall of the receiving cavity 11, and the plurality of combs 32 are arranged 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, for example, the left-right direction in Figure 2 and Figure 3 The included angle α between the combs 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.

[0049] ​The installation plate 31 is detachably installed on the wall of the accommodating cavity 11, the comb teeth 32 are arranged on the plate surface of the installation plate 31, and preferably, the installation plate 31 is detachably installed on the wall of the accommodating cavity 11 through a buckle structure, so that the detachability of the comb tooth component is further improved. When the installation plate 31 is installed on the wall of the accommodating cavity 11, the comb teeth 32 protrude relative to the wall surface of the accommodating cavity 11, and when the cleaning component 2 rotates, the comb teeth 32 can be in contact with the cleaning piece 21, that is, the cleaning piece 21 sweeps across the comb teeth 32, so that the cleaning piece 21 is cleaned, that is, the sundries such as hair and fibers attached to or wound on the cleaning piece 21 are cleaned.

[0050] As shown in Figures 2-5 The plurality of comb teeth 32 are arranged on the installation plate 31 along the longitudinal direction A, the comb teeth 32 extend obliquely relative to the axial direction of the cleaning component 2 (that is, the longitudinal direction A of the accommodating cavity), 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, for example, 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, and preferably, the included angle α is about 70 degrees.

[0051] In the embodiment of the utility model, the "comb teeth" are in the shape of an elongated convex strip, for example, the length L of the comb teeth 32 can be more than 5 times the width W, and preferably more than 10 times.

[0052] The cleaning equipment in the embodiment of the utility model, the comb tooth component is detachably arranged on the wall of the accommodating cavity, so that the comb tooth component is convenient to disassemble, maintain and replace. Meanwhile, the included angle between the comb teeth and the axial direction of the cleaning component is greater than or equal to 65 degrees and less than or equal to 85 degrees, the cleaning piece is not easy to pass through the gap between adjacent comb teeth when sweeping across the comb teeth, the cleaning effect of the comb teeth on the sundries wound on the cleaning piece is improved, the comb teeth do not generate excessive resistance to the cleaning piece, the damage to the cleaning piece is reduced, the cleaning component rotates smoothly, and the energy consumption is low.

[0053] The inventor finds through research that if the included angle α between the comb teeth and the axial direction of the cleaning component is less than 65 degrees, the resistance of the comb teeth to the cleaning piece is greater. If the included angle α between the comb teeth and the axial direction of the cleaning component is greater than 85 degrees, the cleaning piece is easy to pass through the gap between adjacent comb teeth when sweeping across the comb teeth, which affects the cleaning effect of the comb teeth on the cleaning piece.

[0054] Therefore, the cleaning equipment in the embodiment of the utility model is convenient to disassemble and maintain, the cleaning effect of the comb teeth on the cleaning piece is good, and the cleaning component does not need to be frequently disassembled for manual cleaning.

[0055] In some embodiments, the wall of the accommodating cavity 11 is provided with an installation groove 13, the wall of the accommodating cavity 11 and the installation groove 13 can be in the shape of an arc, and the installation plate 31 can be an arc-shaped plate matched with the wall of the accommodating cavity 11 and the installation groove 13, as shown inFigure 6 As shown, the mounting plate 31 is detachably mounted in the mounting groove 13. Preferably, the axial direction of the arc-shaped accommodating cavity 11, the mounting groove 13 and the mounting plate 31 is consistent with the axial direction, i.e. the longitudinal direction A, of the cleaning component 2.

[0056] The mounting plate 31 is detachably mounted in the mounting groove 13, and preferably, the plate surface of the mounting plate 31 provided with the comb teeth 32 is flush with the wall surface of the accommodating cavity 11, and the comb teeth 32 protrude from the wall surface of the accommodating cavity 11, so that the contact between the comb teeth 32 and the cleaning member 21 can be ensured, and the mounting plate 31 is prevented from contacting the cleaning member 21 to block the cleaning member 21.

[0057] In some embodiments, the mounting plate 31 is clamped in the mounting groove 13 through a clamping structure. As shown in Figure 6 The clamping structure includes a clamping groove 313 provided on the rear end of the mounting plate 31 and a clamping protrusion (not shown) provided on the groove wall of the mounting groove 13. When the mounting plate 31 is fitted in the mounting groove 13, the clamping protrusion is fitted in the clamping groove 313, so that the mounting plate can be quickly mounted and detached, and the processing of the mounting plate is facilitated.

[0058] In some embodiments, the comb teeth 32 and the mounting plate 31 are integrally injection molded, so that the cost is low and the processing of the comb tooth component is facilitated.

[0059] 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 along the axial direction of the cleaning component 2, i.e. the first side surface 311 and the second side surface 312 extend along the longitudinal direction A and are opposite to each other in the circumferential direction of the accommodating cavity 11. The comb teeth 32 have a first tooth end 321 and a second tooth end 322 opposite in the axial direction of the cleaning component, the first tooth end 321 of the comb teeth 32 is adjacent to the first side surface 311 of the mounting plate 31, and the second tooth end 322 of the comb teeth 32 is away from the first side surface 311 of the mounting plate 31. The end surface of the first tooth end 321 of the comb teeth 32 can be flush with the first side surface 311 of the mounting plate 31, i.e. the first tooth end 321 of the comb teeth 32 does not protrude beyond the first side surface 311 of the mounting plate 31. Preferably, as shown in Figure 6 The end surface of the first tooth end 321 of the comb teeth 32 protrudes outward beyond the first side surface 311 of the mounting plate 31. Here, "outward" means that the first tooth end 321 of the comb teeth 32 protrudes beyond the first side surface 311 in a direction away from the first side surface 311 of the mounting plate 31, such as a direction orthogonal to the axial direction of the cleaning component, i.e. the left-right direction in Figure 6 As shown in Figure 6 It can be understood that in the example shown in Figure 6 The end surface of the first tooth end 321 of the comb teeth 32 is aligned with the first side surface 311 of the mounting plate 31 in the inclined direction.

[0060] In some embodiments, the mounting plate 31 is disposed adjacent to the dust collection port 12 along the circumferential direction of the accommodating cavity 11, and the mounting plate 31 is located at the downstream side of the dust collection port 12 in the rotating direction of the cleaning member 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 end 321 of the comb tooth 32 is adjacent to the first side surface 311 of the mounting plate 31, and the second tooth end 322 of the comb tooth 32 is away from the first side surface 311 of the mounting plate 31.

[0061] The dust collection port 12 has a first side edge 121 and a second side edge 122 extending along the axial direction of the cleaning member, and the first side edge 121 and the second side edge 122 are opposite to each other along the circumferential direction of the accommodating cavity 11. The first side edge 121 is closer to the mounting plate 31 than the second side edge 122, in other words, the first side edge 121 of the dust collection port 12 is adjacent to the first side surface 311 of the mounting plate 31.

[0062] In the axial direction of the cleaning member 2, the outermost one of the comb teeth 32 is adjacent to the first end 123 of the dust collection port 12 (e.g., the left end of the dust collection port 12 as shown), and the other outermost one of the comb teeth 32 is adjacent to the second end 124 of the dust collection port 12 (e.g., the right end of the dust collection port 12 as shown). Figure 4 Figure 4

[0063] 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, for example, 3 mm, 5 mm, 8 mm, and 10 mm. As shown, the distance is the distance between the first side surface 311 and the first side edge 121 in the up-down direction in the accommodating cavity 11, and since the mounting plate 31 and the wall of the accommodating cavity 11 are arc-shaped, the distance can also be referred to as the distance between the first side surface 311 and the first side edge 121 in the circumferential direction of the accommodating cavity and the mounting plate. Figure 4 Figure 4

[0064] In the process of rotating the cleaning member 2, the cleaning member 21 first sweeps the surface to be cleaned through the opening of the accommodating cavity 11, then passes through the dust collection port 12, the dirt swept is sucked into the dust collection port 12, and then the cleaning member 21 reaches the comb tooth 32 and first contacts the first tooth end 321 of the comb tooth 32. The cleaning member 21 sweeps over the comb tooth 32, so that the comb tooth 32 cleans the sundries wrapped on the cleaning member 21 from the cleaning member 21, and the cleaned sundries are sucked into the dust collection port 12.

[0065] ​​​​The distance between the first side 311 of the mounting plate 31 and the first side edge 121 of the dust collecting opening 12 is greater than zero and less than or equal to 10 mm, and indirectly defines the distance between the first tooth end 321 and the first side edge 121 of the dust collecting opening 12, so that the debris cleaned by the comb teeth 32 is more easily guided into the dust collecting opening 12. If the distance between the first side 311 of the mounting plate 31 and the first side edge 121 of the dust collecting opening 12 is less than zero, the mounting plate 31 extends into the dust collecting opening 12, which affects the airflow into the dust collecting opening 12, increases the wind resistance, and the distance between the first side 311 of the mounting plate 31 and the first side edge 121 of the dust collecting opening 12 is greater than 10 mm, so that the debris is not easily guided into the dust collecting opening, which affects the cleaning effect.

[0066] As shown in Figure 4 and Figure 5 , along the axial direction of the cleaning component 2, i.e. along the left-right direction in Figure 4 and Figure 5 , the leftmost comb tooth is adjacent to the left end of the dust collecting opening 12, and adjacent means that the leftmost comb tooth can be located to the right of the left end of the dust collecting opening 12, or to the left of the left end of the dust collecting opening 12, but adjacent to each other. The rightmost comb tooth 32 is adjacent to the right end of the dust collecting opening 12, and similarly, the rightmost comb tooth can be located to the right of the right end of the dust collecting opening 12, or to the left of the right end of the dust collecting opening 12. That is, the comb teeth correspond to the dust collecting opening, so that the debris such as hair cleaned by the comb teeth 32 is more easily guided towards the dust collecting opening 12, facilitating the debris to be sucked into the dust collecting opening 12, and avoiding the debris to be accumulated at the left and right ends of the accommodation cavity 11.

[0067] In some embodiments, the mounting plate 31 is an arc-shaped structure, i.e. the mounting plate 31 is an arc-shaped plate, the comb teeth 32 include a first group of comb teeth and a second group of comb teeth, the first group of comb teeth and the second group of comb teeth are respectively located on the left and right sides of a center arc B of the mounting plate 31, the center arc B is a center line of the mounting plate 31 perpendicular to the axial direction of the cleaning component 2, and the center arc B can also be referred to as a boundary line of the first group of comb teeth and the second group of comb teeth.

[0068] As shown in Figure 5 , the first group of comb teeth includes a plurality of first comb teeth 32A parallel to each other, and the second group of comb teeth includes a plurality of second comb teeth 32B parallel to each other, the first tooth end 321 of the first comb tooth 32A is closer to the center arc B of the mounting plate 31 than the second tooth end 322 of the first comb tooth 32A, and the first tooth end 321 of the second comb tooth 32B is closer to the center arc B of the mounting plate 31 than the second tooth end 322 of the second comb tooth 32B.

[0069] The plurality of comb teeth 32 are arranged along the left-right direction and divided into the first group of comb teeth and the second group of comb teeth, the first group of comb teeth is located on the left side of the center arc B of the mounting plate 31, and the second group of comb teeth is located on the right side of the center arc B of the mounting plate 31.

[0070] The first set of bristles and the second set of bristles each comprise a plurality of bristles 32, wherein the bristles in the first set of bristles are referred to as first bristles 32A, and the bristles in the second set of bristles are referred to as second bristles 32B, the plurality of first bristles 32A are arranged in parallel to each other, and the plurality of second bristles 32B are arranged in parallel to each other.

[0071] As shown in FIG. 1, the first bristles 32A are inclined downward from left to right, and the second bristles 32B are inclined downward from right to left. Figure 4 The first tooth end 321 of the first bristle 32A is closer to the center arc B of the mounting plate 31 than the second tooth end 322 of the first bristle 32A, in other words, the first bristle 32A is inclined downward from left to right. The first tooth end 321 of the second bristle 32B is closer to the center arc B of the mounting plate 31 than the second tooth end 322 of the second bristle 32B, in other words, the second bristle 32B is inclined downward from right to left.

[0072] The inclination directions of the first bristles 32A and the second bristles 32B are thus arranged, so that the debris cleaned can be better guided towards the dust collection port 12 to be sucked away by the dust collection port, avoiding the accumulation of the debris cleaned at the two ends of the accommodation cavity.

[0073] In some embodiments, the first tooth end 321 of the innermost first bristle 32A and the first tooth end 321 of the innermost second bristle 32B meet 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, and the tip of the V-shape faces the dust collection port 12 in the rotation direction of the cleaning member 2.

[0074] The rightmost first bristle and the leftmost second bristle form a V-shape, which can avoid the middle cleaning member passing through the gap between the rightmost first bristle and the leftmost second bristle.

[0075] The distance S between the tip of the V-shape and the first side surface 311 of the mounting plate 31 (i.e. the distance between the tip of the V-shape and the upper edge of the first side surface 311) can be 1.5 mm-3.5 mm, for example, 1.5 mm, 2.0 mm, 2.5 mm, 3.5 mm. The upper edge of the end face of the first tooth end 321 of the remaining bristles 32 is flush with or outwardly exceeds the first side surface 311 of the mounting plate 31 (side surface upper edge). If the distance S is less than 1.5 mm, the first bristle and the second bristle forming the V-shape form a larger resistance to the cleaning member, which affects the rotation of the cleaning member, and if the distance S is greater than 1.5 mm, the cleaning effect is poor.

[0076] In some embodiments, the first set of bristles and the second set of bristles are symmetrical relative to the center line of the V-shape, and the center line of the V-shape can be the center arc B of the mounting plate. As shown in FIG. 1, the first set of bristles and the second set of bristles are symmetrical relative to the center line of the V-shape. Figure 5As shown, the multiple first comb teeth 32A of the first group of comb teeth and the multiple second comb teeth 32B of the second group of comb teeth are symmetrical with respect to the center line B of the V-shape. In other words, the multiple first comb teeth 32A of the first group of comb teeth and the multiple second comb teeth 32B of the second group of comb teeth correspond one to one with respect to the center arc line B of the mounting plate 31 and are symmetrical to each other, so that the cleaned debris can be better guided toward the dust collecting port to avoid the cleaned debris from accumulating at both ends of the accommodating cavity.

[0077] In some embodiments, in a cross section of the mounting plate 31 parallel to the axial direction of the cleaning component 2, the height H of the plurality of comb teeth 32 gradually decreases from the center arc line of the mounting plate 31 toward the two ends of the mounting plate 31. Optionally, the plurality of comb teeth 32 have at least two different heights H, and the comb teeth 32 of different heights H are alternately arranged along the axial direction of the cleaning component 2.

[0078] like Figure 7 As shown, in the cross section of the mounting plate 31 parallel to the axial direction of the cleaning component 2, the heights of the plurality of comb teeth 32 can be the same, or they can gradually decrease from the center arc of the mounting plate 31 toward the left and right ends of the mounting plate 31. In other words, the heights of the plurality of first comb teeth 32A can be the same, or they can gradually decrease from right to left, and the heights of the plurality of second comb teeth 32B can be the same, or they can gradually decrease from left to right. Here, "in the cross section" means that when the comb teeth vary along the length direction of the comb teeth and a single comb tooth has multiple height values, the height comparison of different comb teeth is to compare the heights of multiple comb teeth at the same position. Of course, when the height of a single comb tooth remains unchanged along the length direction, each comb tooth has a single height. Here, the height of the comb teeth refers to the height of the comb teeth in the cross section. Figure 8 In the cross section shown, the vertical dimension of the highest point of the comb teeth is shown. In the present invention, the height of the comb teeth can also be replaced by the thickness T of the comb teeth.

[0079] In the cross section, the plurality of comb teeth 32 may also have at least two different heights and the comb teeth 32 of different heights may be alternately arranged along the axial direction of the cleaning member 2. For example, the first comb teeth 32A may be 10, from the left side toward the right side, the first to third comb teeth have the same height and are the lowest, the height of the fourth comb tooth is greater than the height of the first to third comb teeth, the height of the fifth to seventh comb teeth is the same and greater than the height of the fourth comb tooth, the height of the ninth to tenth comb teeth is the same and equal to the height of the fifth to seventh comb teeth, and the height of the eighth comb tooth is greater than the height of the fourth comb tooth but less than the height of the ninth to tenth comb teeth. The second comb teeth 32B may be symmetrically arranged with the first comb teeth 32A. Alternatively, the comb teeth of different heights may be arranged in other alternating manners.

[0080] The comb teeth of different heights are arranged alternately, which can penetrate into different depths of the cleaning object, further improving the cleaning effect and reducing the resistance to the cleaning object.

[0081] In some embodiments, the height of the comb tooth 32 decreases from the first tooth end 321 of the comb tooth 32 towards the second tooth end 322 of the comb tooth 32, which can be gradually decreased or decreased in steps. Optionally, the height of the first tooth end 321 of the comb tooth 32 is greater than the height of the rest of the comb tooth 32, i.e. the first tooth end 321 is the highest, as shown in Figure 6 In other words, the top portion of the first tooth end 321 is further away from the mounting plate 31 than the top portion of the rest of the comb tooth 32. When the mounting plate and the accommodating cavity are arc-shaped, the height H of the comb tooth 32 can be the dimension of the comb tooth 32 along the radial direction of the accommodating cavity 11.

[0082] 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.

[0083] Optionally, 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, the plurality of comb teeth 32 with different heights of the second tooth ends 322 are arranged alternately, and the plurality of comb teeth 32 have at least two sizes extending into the cleaning member 21 to clean debris at different depths of the cleaning member 21, further improving the cleaning effect.

[0084] In some embodiments, the two side surfaces 302 of the comb tooth 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 tooth 32 is further away from the center arc than the bottom edge 3022 of the side surface 302. More specifically, as shown in Figure 7 The first comb tooth 32A is inclined to the left and the second comb tooth 32B is inclined to the right.

[0085] As shown in Figure 7 The two side surfaces of the comb tooth 32 opposite in the left-right direction are parallel to each other and inclined relative to the mounting plate 31, in other words, the side surfaces of the left and right sides of the comb tooth 32 are not orthogonal to the mounting plate 31, for example, the included angle β between the side surfaces of the left and right sides of the comb tooth 32 and the mounting plate 31 is not equal to 90°.

[0086] 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 edge of the side surface 302 and the top surface 301 of the comb tooth 32, and the bottom edge 3022 is the intersection edge of the side surface 302 and the mounting plate 31. The top edge 3021 of the side surface 302 is further 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 arranged from left to right in the direction towards the mounting plate 31, and the side surface 302 of the second comb tooth 32B is arranged from right to left in the direction towards the mounting plate 31.

[0087] The inclination direction of the side surface 302 of the first comb tooth 32A and the inclination direction of the side surface 302 of the second comb tooth 32B can guide the debris cleaned to the middle of the mounting plate 31, and then to the dust collection port 12.

[0088] 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 surface of the second tooth end 322 and the two side surfaces 302 of the comb tooth 32, respectively.

[0089] As shown in FIG. 6, 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 preferably, the width of the first tooth end 321 of the comb tooth 32 is reduced compared to the width of the rest of the comb tooth, thereby forming a sharp end. Thus, the comb tooth 32 is easier to enter the cleaning member 21. Figure 5 As shown in FIG. 7, the top surface 301 of the comb tooth 32 is arc transitioned with the end surface of the second tooth end 322, and the top surface 301 of the comb tooth 32 is arc transitioned with the left and right side surfaces 302, thereby reducing the resistance of the comb tooth 32 to the cleaning member 21.

[0090] Figure 6 As shown in FIG. 8, the top surface 301 of the comb tooth 32 is arc transitioned with the end surface of the second tooth end 322, and the top surface 301 of the comb tooth 32 is arc transitioned with the left and right side surfaces 302, thereby reducing the resistance of the comb tooth 32 to the cleaning member 21.

[0091] In some embodiments, the spacing P between adjacent comb teeth 32 gradually increases from the center arc B of the mounting plate 31 to the two ends of the mounting plate 31. Alternatively, the spacing P between adjacent comb teeth 32 has at least two different spacings P, and the different spacings are arranged alternately along the axial direction of the cleaning member 2.

[0092] As shown in FIG. 9, the spacing P between adjacent comb teeth 32 gradually increases from the center arc of the mounting plate 31 to 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. Figure 5 Alternatively, the spacing P between adjacent comb teeth 32 has at least two different spacings P, and the different spacings are arranged alternately along the axial direction of the cleaning member 2, for example, the spacings include a first spacing and a second spacing, the first spacing is greater than the second spacing, and a plurality of first spacings and a plurality of second spacings are arranged alternately in the left-right direction to reduce the resistance of the comb tooth 32 to the cleaning member 21.

[0093] In some embodiments, the maximum spacing between adjacent comb teeth 32 is greater than or equal to 1.5 millimeters and less than or equal to 3 millimeters.

[0094] As shown in FIG. 10, the maximum spacing between adjacent comb teeth 32 is greater than or equal to 1.5 millimeters and less than or equal to 3 millimeters.

[0095] Figure 5 ​​As shown, except for the first rightmost comb tooth 32A and the second leftmost 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. Preferably, the spacing is 1.5 mm, 1.8 mm, 2.3 mm, or 3 mm.

[0096] If the spacing P is greater than 3 mm, the cleaning element 21 and debris will easily pass between two adjacent comb teeth 32, thereby affecting the cleaning effect of the cleaning element 21. If the spacing P is less than 1.5 mm, it will produce greater resistance to the rotation of the cleaning element 21, and also affect the cleaning effect of the cleaning element 21.

[0097] In some embodiments, the width W of the widest part of the comb teeth 32 is greater than or equal to 1 mm and less than or equal to 2 mm, the length L of the comb teeth 32 is greater than or equal to 10 mm and less than or equal to 20 mm, the height H of the highest part of the comb teeth 32 is greater than or equal to 2.5 mm and less than or equal to 5 mm, and the height of the lowest part of the comb teeth 32 is greater than or equal to 1 mm and less than or equal to 2 mm.

[0098] like Figure 5 As shown, the width W of the widest part of the comb teeth 32 is greater than or equal to 1 mm and less than or equal to 2 mm, preferably 1 mm, 1.2 mm, 1.6 mm, or 2 mm.

[0099] The length L of the comb teeth 32 is greater than or equal to 10 mm and less than or equal to 20 mm, and is preferably 10 mm, 15 mm, 18 mm, or 20 mm.

[0100] 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, and is preferably 2.5 mm, 2.8 mm, 3.5 mm, or 5 mm.

[0101] 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, and is preferably 1 mm, 1.5 mm, 1.8 mm, or 2 mm.

[0102] If the width W, length L and height H of the comb teeth 32 are too large, the resistance will be increased, affecting the rotation of the cleaning member 21 . If they are too small, the cleaning effect of the cleaning member 21 will be reduced.

[0103] In some embodiments, the cross-section of the accommodating cavity 11 is an arc shape, the dust collecting 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 collecting port 12 is greater than or equal to 50 mm and less than or equal to 80 mm, and the width of the dust collecting port 12 is greater than or equal to 15 mm and less than or equal to 25 mm.

[0104] like Figure 3 and Figure 4As shown, the cross section of the accommodating cavity 11 is preferably semicircular, and the diameter of the accommodating cavity 11 is greater than or equal to 40 mm and less than or equal to 60 mm, preferably 40 mm, 45 mm, 47 mm, 50 mm, 52 mm, 55 mm, 58 mm, or 60 mm.

[0105] The dust collecting port 12 can be a rounded rectangle or a rounded trapezoid, and the length D of the dust collecting port 12 along the left-right direction is greater than or equal to 50 mm and less than or equal to 80 mm. When the dust collecting port 12 is a rounded trapezoid, the length D of the dust collecting port 12 changes, and the distance (length) between the first side 121 and the second side 122 of the dust collecting port 12 is greater than or equal to 50 mm and less than or equal to 80 mm. Preferably, the length D of the dust collecting 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. Preferably, the length of the first side 121 is 50 mm and the length of the second side 122 is 70 mm. Alternatively, the length of the first side 121 is 60 mm and the length of the second side 122 is 80 mm.

[0106] Along the circumference of the accommodating cavity 11 , the width K of the dust collecting port 12 is greater than or equal to 15 mm and less than or equal to 25 mm, preferably 15 mm, 18 mm, 22 mm, or 25 mm.

[0107] The size of the accommodating cavity 11 and the size of the dust collecting port 12 are correlated and matched, thereby improving the cleaning effect of the surface to be cleaned, the suction force of the dust collecting port 12 and the dust collecting effect.

[0108] In some embodiments, the cleaning component 2 includes a rotating shaft 22, a baffle 23, and a cleaning member 21. The baffle 23 is mounted on the first and second rotating ends of the rotating shaft 22, respectively. A barrier is provided on at least a portion of the outer circumference of the baffle 23. The cleaning member 21 includes at least one bristle row. The bristle row includes a first section 211 and a second section 212. The first section 211 and the second section 212 extend spirally around the axial direction of the rotating shaft 22. The spiral directions of the first section 211 and the second section 212 are opposite. The connection between the first section 211 and the second section 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 between the first section 211 and the second section 212 correspond to each other.

[0109] like Figure 8 As shown, the cleaning component 2 includes a rotating shaft 22, a baffle 23 and a cleaning member 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 accommodating chamber 11, and the right end of the rotating shaft 22 is rotatably supported on the right end of the accommodating chamber 11. The left end or the right end of the rotating shaft 22 is connected to the driver in the body 1, and the driver is preferably but not limited to a rotating motor.

[0110] The left and right ends of the rotating shaft 22 are provided with coaxial baffle plates 23, and the entire outer circumferential surface or part of the outer circumferential surface of the baffle plate 23 is provided with a barrier, which is preferably but not limited to a fluff, for blocking the swept sundries between the left and right ends of the rotating shaft 22 and the machine body 1.

[0111] The bristle row can be one, two, three, or more. When the bristle row is multiple, the multiple bristle rows are arranged along the circumferential direction of the rotating shaft 22.

[0112] The bristle row is divided into a first section 211 and a second section 212 along the left-right direction, the first section 211 is located on the left side of the second section 212, the first section 211 and the second section 212 extend spirally around the axial direction 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 row is V-shaped, and the connection between 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 collecting port 12 and the position of the mounting plate 31.

[0113] During the rotation of the cleaning component 2, the first section 211 sweeps across the first comb group, and the second section 212 sweeps across the second comb group. The first section 211 and the second section 212 with opposite spiral directions guide the swept sundries towards the dust collecting port 12, so as to be sucked into the dust collecting port 12, and at the same time, the sundries such as hair cleaned by the comb are guided towards the dust collecting port 12, thereby improving the cleaning effect.

[0114] In some embodiments, the bristle row extends spirally around the axial direction of the rotating shaft 22, the first rotating end of the rotating shaft 22 is rotatably supported on the machine body 1, the second rotating end of the rotating shaft 22 is suspended, and the position of the dust collecting port 12 and the position of the mounting plate 31 are adjacent to the second rotating end of the rotating shaft 22. Specifically, the position of the dust collecting port 12 and the position of the mounting plate 31 are adjacent to the second rotating end of the rotating shaft 22. The bristle row guides the swept sundries towards the second rotating end of the rotating shaft 22, so as to be sucked into the dust collecting port 12, thereby improving the cleaning effect.

[0115] The first rotating end of the rotating shaft 22 is provided with a coaxial baffle plate 23, and the entire outer circumferential surface or part of the outer circumferential surface of the baffle plate 23 is provided with a barrier, which is preferably but not limited to a fluff, for blocking the swept sundries between the first rotating end of the rotating shaft 22 and the machine body 1.
