The suction port 104 can be arranged on the bottom surface of the main body 10, and can be used to suck the dust and hair on the surface of the textile into the receiving cavity 101 communicated with the suction port 104, so as to be brought to the roller brush assembly 20. Wherein, the textile is for example a textile clothing or a quilt cover or a quilt and the like.

[0037] The roller brush assembly 20 is arranged in the receiving cavity 101 and rotationally connected with the main body 10, the roller brush assembly 20 can be arranged on the side wall of the receiving cavity 101, and the roller brush assembly 20 can be located between the air inlet 103 and the suction port 104. The roller brush assembly 20 is arranged in the receiving cavity 101, specifically, the roller brush assembly 20 can be arranged in the receiving cavity 101 formed at the bottom of the main body, and in this embodiment, the roller brush assembly 20 can be arranged at a position below the air inlet 103. Wherein, the roller brush assembly 20 includes for example a first roller brush 30 and a second roller brush 40. Specifically, a surface of the first roller brush 30 is provided with a first cleaning part 31 arranged in a helical manner along an axial direction of the first roller brush (such as the X direction shown in the figure), and the first roller brush 30 is rotationally connected with the main body 10; the first roller brush 30 can be arranged on one side wall in the receiving cavity 101 at the bottom of the main body 10, the second roller brush 40 is also rotationally connected with the main body 10, and the second roller brush 40 is arranged in a helical manner along the axial direction of the first roller brush 30 (such as the X direction shown in the figure). Figure 2 Wherein, the first cleaning part 31 of the first roller brush 30 is arranged in a helical manner along the axial direction of the first roller brush 30, and the second cleaning part 41 of the second roller brush 40 is arranged in a helical manner along the axial direction of the second roller brush 40, and the first cleaning part 31 and the second cleaning part 41 are arranged in opposite directions. Wherein, the first roller brush 30 and the second roller brush 40 are arranged in the receiving cavity 101 formed at the bottom of the main body 10, and in this embodiment, the first roller brush 30 and the second roller brush 40 are arranged at a position below the air inlet 103. Figure 2The second rolling brush member 40 is arranged on the side wall of the accommodating cavity 101 at the bottom of the main body member 10, and specifically, the second rolling brush member 40 is arranged on the side wall of the accommodating cavity 101 corresponding to the side wall of the accommodating cavity 101 where the first rolling brush member 30 is arranged. The first rolling brush member 30 and the second rolling brush member 40 can be a rolling brush, and the first rolling brush member 30 and the second rolling brush member 40 can be a cylindrical rolling brush. The first rolling brush member 30 and the second rolling brush member 40 are arranged in the X direction, and the central axis of the second rolling brush member 40 corresponds to the central axis of the first rolling brush member.

[0038] The first rolling brush member 30 and the second rolling brush member 40 are spaced apart and have a spacing position 51 therebetween. The end of the second rolling brush member 40 close to the first rolling brush member 30 is spaced apart from the end of the first rolling brush member 30 close to the second rolling brush member 40, that is, the ends of the first rolling brush member 30 and the second rolling brush member 40 close to each other are discontinuous rather than connected together.

[0039] The spacing position 51 is a spacing, that is, the first rolling brush member 30 and the second rolling brush member 40 are not connected, and the first rolling brush member 30 and the second rolling brush member 40 are respectively connected to the two opposite side walls at the bottom of the main body member. Meanwhile, the ends of the first rolling brush member 30 and the second rolling brush member 40 close to each other are spaced apart to form a space, and the air inlet 103 is used to absorb the hair, dust and other impurities obtained by the rolling brush assembly 20 beating the surface of the textile.

[0040] In this embodiment, the second rolling brush member 40 is coaxially arranged with the first rolling brush member 30, that is, the second rolling brush member 40 is opposite to the first rolling brush member 30, and then the first rolling brush member 30 and the second rolling brush member 40 are spaced apart and have a spacing position 51 therebetween. When the cleaning device 1 is working, the hair is first brought to the first rolling brush member 30 and the second rolling brush member 40 through the suction port 104, and then the first cleaning part 31 and the second cleaning part 41 are driven to work by the rotation of the first rolling brush member 30 and the second rolling brush member 40, and the hair is brought to the position of the spacing position 51, and then the hair is absorbed by the suction of the air inlet 103, so that the hair can be prevented from winding around the first rolling brush member 30 and the second rolling brush member 40, so that the cleaning device 1 can continue to work, the cleaning efficiency of the cleaning device 1 is improved, the cleaning amount of the user is reduced, and the use and experience of the user are improved.

[0041] Further, the suction port 104 can be arranged corresponding to the positions of the first and second rolling brush members 30 and 40, so that part of the first and second cleaning portions 31 and 41 are exposed on the surface of the suction port 104, so that when the cleaning device 1 hits the surface of the textile, the hair and dust on the surface of the textile can be brought into the rolling brush assembly 20 by the first and second cleaning portions 31 and 41.

[0042] Further, the interval position 51 is arranged corresponding to the position of the air inlet 103, and the interval position 51 can be located below the air inlet 103 and can communicate with the air inlet 103. That is, the position of the air inlet 103 corresponds to the position of the interval position 51. When the lengths of the first and second rolling brush members 30 and 40 are consistent, the interval position 51 can be located at the middle position of the rolling brush assembly 20, and at this time, the air inlet 103 can be arranged in the main body member 10 close to the center of one side of the rolling brush assembly 20. In other embodiments, the position of the interval position 51 can be adjusted according to the length of the first and second rolling brush members 30 and 40, and the position of the air inlet 103 will also be adjusted accordingly, which is not limited here.

[0043] Further, when the lengths of the first and second rolling brush members 30 and 40 are consistent, the interval length of the interval position 51 is 1 / 10 of the length of the rolling brush of the first rolling brush member 30, and the interval length of the interval position 51 is, for example, 3-5 mm, and specifically, 3 mm or 4 mm or 5 mm, but the interval length of the interval position 51 must be greater than the diameter of the hair, so that the hair entering the first and second rolling brush members 30 and 40 from the suction port 104 can smoothly pass through the gap to reach the air inlet 103. The distance of the air inlet 103 along the axial direction of the first rolling brush member 30 is greater than the interval length of the interval position 51. The air inlet 103 is, for example, a rectangular air inlet, and the distance of the air inlet 103 along the axial direction of the first rolling brush member 30 can be, for example, the length of the air inlet 103, which is greater than the interval length of the interval position 51. The length of the air inlet 103 can be, for example, 30-35 mm, and specifically, for example, 30 mm, 32 mm or 35 mm. In this embodiment, by limiting the length of the air inlet 103 to be greater than the interval length of the interval position 51, it is ensured that the hair and other sundries can smoothly enter the air inlet 103, and the hair is further prevented from winding around the first and second rolling brush members 30 and 40, thereby reducing the influence on the cleaning efficiency of the cleaning device 1.

[0044] Further, the distance of the air inlet 103 along the direction perpendicular to the axial direction of the first rolling brush member 30 (i.e. the direction perpendicular to the X direction) is greater than the diameter of the first rolling brush member 30 and / or the second rolling brush member 40. The air inlet 103 is for example a rectangular air inlet, and the distance of the air inlet 103 along the direction perpendicular to the axial direction of the first rolling brush member 30 is for example the width of the air inlet 103, which is less than the diameter of the first rolling brush member 30 and / or the second rolling brush member 40. The width of the air inlet 103 is for example 15-20 mm, and is for example 15 mm, 18 mm or 20 mm. By limiting the width of the air inlet 103 to be greater than the diameter of the rolling brush, it is also ensured that the hair and other sundries can smoothly enter the air inlet 103, further reducing the entanglement of the hair and improving the cleaning efficiency of the cleaning device 1.

[0045] Further, as shown in Figures 4-5 and Figures 7-8 , the first rolling brush member 30 comprises a first end portion 301 connected to the side wall of the accommodating cavity 101. The first rolling brush member 30 is provided with a bearing 32 and a bearing seat 33. The bearing 32 is arranged close to the first end portion 301, and the bearing seat 33 is arranged around the bearing 32 and is rotationally connected to the bearing 32. By arranging the bearing seat 33 and the bearing 32 to fix the rotation of the first rolling brush member 30, the left and right swing of the first rolling brush member 30 is reduced.

[0046] Further, the distance from the bearing 32 to the first end portion 301 is 1 / 20-1 / 5 of the length of the first rolling brush member 30. For example, the distance from the bearing 32 to the first end portion 301 is 1 / 20, 1 / 10 or 1 / 5 of the length of the first rolling brush member 30. By limiting the arrangement position of the bearing 32, the inclination and swing of the first rolling brush member 30 during rotation is further avoided, and the normal operation of the first rolling brush member 30 is ensured.

[0047] Further, as shown in Figures 4-5 and Figures 7-8As shown, the main body 10 is further provided with a connecting portion 11, which is arranged in the accommodating cavity 101 and on the side wall of the accommodating cavity 101 close to the first end portion 301, and the first end portion 301 is provided with a limiting portion 34 corresponding to the connecting portion 11, and the connecting portion 11 is fixedly connected with the limiting portion 34. The connecting portion 11 is, for example, a power shaft, which is connected with a driving portion 14 in the cleaning device, the driving portion 14 is arranged in the accommodating cavity 101 and connected with the roller brush assembly 20, and the driving portion 14 can be used to drive the roller brush assembly 20 to rotate. The power shaft can be provided with a cross-shaped bone position, and the limiting portion 34 is, for example, a cross-shaped limiting groove corresponding to the cross-shaped bone position. Through the connection of the limiting groove and the bone position, the first end portion 301 of the first roller brush 30 can be fixed on the connecting portion 11. Moreover, the connecting portion 11 is connected with the driving portion 14, the connecting portion 11 is driven to rotate by the driving portion 14, and then the first roller brush 30 is driven to rotate by the cooperation of the connecting portion 11 and the limiting portion 34, so as to realize the rotation of the first roller brush 30. Through the cooperation of the limiting portion 34 and the connecting portion 11, the side wall of the accommodating cavity 101 supports the first end portion 301 of the first roller brush 30, and further avoids the inclination and swing of the first roller brush 30 during rotation.

[0048] Further, the connecting portion 11 is a protrusion, and the limiting portion 34 is a groove, and the groove corresponds to and is fixedly connected with the protrusion. The protrusion is, for example, a cross-shaped protrusion, and the groove is, for example, a limiting groove, which is, for example, a cross-shaped limiting groove corresponding to the cross-shaped protrusion. Through the cooperation of the protrusion and the groove, the first roller brush 30 is connected with the side wall of the accommodating cavity 101. In other embodiments, the connecting portion 11 can be, for example, a groove, and the limiting portion 34 can be, for example, a protrusion. The specific structures of the connecting portion 11 and the limiting portion 34 can be arranged according to actual conditions, and are not limited herein.

[0049] Further, as shown in Figure 3 and Figure 6 The cleaning device 1 further comprises, for example, a cover plate 13, which is arranged on one end of the main body 10 close to the roller brush assembly 20 and connected with the main body 10, covers the roller brush assembly 20, and covers the connecting portion 11 and the bearing 32. The cover plate 13 is, for example, a cover plate with a certain strength. When the cleaning device 1 is working, the cover plate 13 covers the connecting portion 11 and the bearing 32, so as to prevent hair from entering the bearing 32 and the connecting portion 11 and prevent the hair from winding around the bearing 32 and the connecting portion 11.

[0050] Further, as shown in Figure 7As shown, the first cleaning part 31 comprises a first brush strip 311 arranged on the side wall surface of the first roller brush piece 30; wherein the first roller brush piece 30 further comprises a second end 302 opposite to the first end 301, the second end 302 can be located above the air inlet 103, and the first brush strip 311 is spirally arranged from the bearing 32 to the second end 302. The first brush strip is, for example, a long strip-shaped brush strip, which can be made of silica gel, for example. The brush strip is spirally arranged on the surface of the first roller brush piece 30, and the first brush strip 311 is used to guide the hair, dust and other impurities entering the side wall surface of the first roller brush piece 30 to the interval position 51, so as to facilitate the air inlet 103 to absorb the impurities and bring them into the collection bin 102. The first brush strip 311 is spirally arranged from the bearing 32 to the second end 302. For example, the first roller brush piece 30 is a cylindrical roller brush, the first end 301 is, for example, the bottom of the first roller brush piece 30, and the second end 302 can be, for example, the top of the first roller brush piece 30. The first brush strip 311 extends from the bearing 32 close to the first end 301 to the second end 302, that is, from the bottom to the top of the first roller brush piece 30, which is equivalent to extending upward. At the same time, the first brush strip 311 is arranged around the surface of the side wall of the first roller brush piece 30, and extends upward while being arranged around, thereby forming the spiral arrangement of the first brush strip 311. When the first roller brush piece 30 rotates in a certain direction, for example, clockwise, the hair entering the first roller brush piece 30 will be pushed to the second end 302 of the first roller brush piece 30 along the spirally arranged first brush strip 311. Since the interval position 51 is arranged adjacent to the second end 302, the hair will be sucked into the air inlet 103, thereby reducing the retention of hair in the air inlet 103. The present embodiment defines the spiral extension direction of the first brush strip 311 from the bearing 32 to the second end 302 of the first roller brush piece 30, so as to ensure that the cooperation of the first brush strip 311 and the first roller brush piece 30 pushes the hair and other impurities upward to the air inlet 103 and is sucked into the air inlet 103, thereby reducing the occurrence of hair entanglement of the first roller brush piece 30.

[0051] Further, as Figure 7As shown, in the X direction, the first brush strip 311 spirals and extends from the bearing 32 to the second end portion 302 in the rotation direction of the first rolling brush piece 30, wherein the rotation direction of the first rolling brush piece 30 is opposite to the spiral extension direction of the first brush strip 311. By defining the spiral extension direction of the first brush strip 311 opposite to the rotation direction of the first rolling brush piece 30, at the same time, the rotation direction of the first rolling brush piece 30 is the same as the rotation direction of the second rolling brush piece 40. It is further ensured that the first brush strip 311 can push the hair to the upper side of the air inlet 103, that is, to the interval position 51, so that the hair can be sucked into the air inlet 103. And the rotation direction of the first rolling brush piece 30 is the same as the rotation direction of the second rolling brush piece 40, that is, the rotation direction of the first rolling brush piece 30 and the second rolling brush piece 40 both push the hair to the air inlet 103, thereby reducing the accumulation of hair on the first rolling brush piece 30 and the second rolling brush piece 40.

[0052] In a preferred embodiment of the present embodiment, as shown in Figure 3 As shown, the surface of the cover piece 13 is formed with the suction port 104, and part of the first brush strip 311 is exposed to the suction port 104, that is, the width of the first brush strip 311 is greater than the minimum distance from the side wall of the first rolling brush piece to the cover. By defining the width of the first brush strip 311 greater than or equal to the distance from the rolling brush to the cover piece 13, it can be ensured that the first brush strip 311 can contact impurities from the outside, and when the first rolling brush piece 30 rotates, it can continuously grasp dust, mites and hair and other impurities on the surface of the textile (such as clothes, quilts, etc.), thereby improving the de-mite efficiency of the cleaning device 1 during work.

[0053] As shown in Figure 8 The first cleaning part 31 further comprises a second brush strip 312, which is arranged on the surface of the side wall of the first rolling brush piece 30, and the first brush strip 311 and the second brush strip 312 are arranged in a spaced manner, and in the X direction, the second brush strip 312 spirally extends from the first end portion 301 to the second end portion 302, wherein the spiral direction of the second brush strip 312 is the same as the spiral direction of the first brush strip 311. By arranging the first brush strip 311 and the second brush strip 312, the contact points of the first rolling brush piece 30 with the surface of the textile are more, thereby further improving the de-mite efficiency of the cleaning device 1 and avoiding hair entanglement.

[0054] In a preferred embodiment of the present embodiment, the surface of the first rolling brush piece 30 can further be provided with a bristle portion, which can be arranged on the interval between the first brush strip 311 and the second brush strip 312.
