[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1 and Figure 2As shown, the roller brush 10 of the present invention includes a roller 1, a plurality of blades 2, and a bristle group 3. The blades 2 extend along the axial direction of the roller 1 and are connected to the roller 1. The bristle group 3 includes bristles arranged along the axial direction of the roller 1. The plurality of blades 2 are arranged at intervals along the circumference of the roller 1. The bristle group 3 is arranged between two adjacent blades 2 and is connected to the roller 1.

[0028] When the roller brush 10 of the embodiment of the present invention is used in a sweeper, the roller 1 drives the blade 2 and the bristle group 3 to rotate, the blade 2 is used to contact the ground and play a supporting role, and the bristles of the bristle group 3 can pick up hair on the ground, thereby effectively cleaning the hair on the ground and improving the cleaning effect of the sweeper.

[0029] Optionally, the blade 2 is a flexible blade.

[0030] For example, the blade 2 is made of rubber.

[0031] By configuring the blade 2 as a flexible blade, the blade 2 can be in more stable contact with the ground, thereby improving the reliability of the roller brush 10 .

[0032] In some embodiments, the bristles are flexible bristles. Figure 1 and Figure 2 As shown, the size of the bristle group 3 in the radial direction of the roller 1 is larger than the size of the blade 2 in the radial direction of the roller 1 .

[0033] For example, the bristles are nylon bristles.

[0034] like Figure 1 As shown, the size of the bristle group 3 in the radial direction of the roller 1 is L1, and the size of the bristle group 3 in the radial direction of the roller 1 is L2, and L2 is larger than L1.

[0035] By making the radial dimension of the bristle group 3 larger than that of the blades 2 in the roller 1, the motion envelope of the bristle group 3 is larger than that of the blades 2 when the roller brush 10 rotates. This facilitates the bristles to pick up hair on the floor, improving the cleaning effect of the sweeper. In addition, because the bristles are flexible, they can maintain contact with the floor by deforming.

[0036] In some embodiments, two adjacent blades 2 are respectively a first blade and a second blade, the first blade is arranged in front of the second blade in the rolling direction of the roller 1, and the bristle group 3 is arranged toward the first blade.

[0037] For example, Figure 1 and Figure 2 As shown, the rolling direction of the roller 1 is shown by the arrow a in the figure, and the bristle group 3 is arranged closer to the first blade.

[0038] Therefore, when the roller 1 drives the blade 2 and the bristle group 3 to rotate, the first blade can provide better support for the bristles of the bristle group 3, which is beneficial for the bristles of the bristle group 3 to pick up hair on the ground and improve the cleaning effect of the sweeper.

[0039] In some embodiments, as Figure 2 As shown, the blade 2 includes a blade bending section, which includes two blade segments 21 connected in series. Both blade segments 21 are arranged at an angle relative to the axial direction of the roller 1, forming a V-shaped structure. The bristle group 3 includes a bristle bending section, which includes two bristle segments 31 connected in series. Both bristle segments 31 are arranged at an angle relative to the axial direction of the roller 1, forming a V-shaped structure. The inclination direction of the bristle segments 31 is the same as that of the blade segments 21.

[0040] By setting the blade bending section of blade 2 to a V-shaped structure, and setting the bristle bending section of bristle group 3 to a V-shaped structure, and the inclination direction of bristle segment 31 is the same as the inclination direction of blade segment 21, so that during the rotation of roller 1, the middle part of the V-shaped structure of blade 2 and the middle part of the V-shaped structure of bristle group 3 can be used to collect hair wrapped around roller brush 10, which is convenient for cleaning the hair on roller brush 10 and improves the user experience of the sweeper.

[0041] Optionally, the blade 2 as a whole forms a blade bending section, and the bristle group 3 as a whole forms a bristle bending section. In other words, the blade 2 as a whole forms a V-shaped structure, and the bristle group 3 as a whole forms a V-shaped structure.

[0042] In this way, the hair wrapped around the roller brush 10 can be collected more effectively, improving the user experience of the sweeper.

[0043] Optionally, the angle between the blade segment 21 and the axial direction of the roller 1 is equal to the angle between the bristle segment 31 and the axial direction of the roller 1 .

[0044] For example, Figure 4 As shown, the included angle between the bristle segment 31 and the axial direction of the roller 1 is α.

[0045] By setting the angle between the blade segment 21 and the axial direction of the roller 1 to be equal to the angle between the bristle segment 31 and the axial direction of the roller 1, the blade 2 can better support the bristles of the bristle group 3, which is beneficial for the bristles of the bristle group 3 to pick up hair on the ground and improve the cleaning effect of the sweeper.

[0046] Optionally, the angle between the blade segment 21 and the axial direction of the roller 1 is 30° to 70°, and the angle between the bristle segment 31 and the axial direction of the roller 1 is 30° to 70°.

[0047] For example, if α is 35°, the angle between the blade segment 21 and the axial direction of the roller 1 is also 35°.

[0048] It can be understood that, the larger the angle between the blade segment 21 and the axial direction of the roller 1, and the angle between the bristle segment 31 and the axial direction of the roller 1, the easier it is for the V-shaped structure to collect hair, but the more difficult it is to process the roller brush 10; the smaller the angle between the blade segment 21 and the axial direction of the roller 1, and the angle between the bristle segment 31 and the axial direction of the roller 1, the easier it is to process the roller brush 10, but the more difficult it is to collect hair with the V-shaped structure.

[0049] By setting the angle between the blade segment 21 and the axial direction of the roller 1 to 30°~70°, and the angle between the bristle segment 31 and the axial direction of the roller 1 to 30°~70°, the V-shaped structure can ensure the hair collection effect while facilitating the processing and manufacturing of the roller brush 10.

[0050] Optionally, the number of blades 2 is 2 to 8, and the number of bristle groups 3 is 2 to 4.

[0051] For example, the number of blades 2 is four, and the number of bristle groups 3 is two.

[0052] By setting the number of blades 2 to 2 to 8 and the number of bristle groups 3 to 2 to 4, the number of blades 2 and bristle groups 3 can be reduced while ensuring the cleaning effect of the roller brush 10, thereby facilitating the processing and manufacturing of the roller brush 10.

[0053] Optionally, the roller brush 10 further includes end parts 4 provided at both ends of the roller shaft 1 , and both ends of the blade 2 extend into the corresponding end parts 4 respectively.

[0054] For example, Figure 2 and Figure 3 As shown, the two end parts 4 are respectively a first end part 41 and a second end part 42 , and the two ends of the blade 2 are respectively a first end 201 and a second end 202 , the first end 201 extends into the first end part 41 , and the second end 202 extends into the second end part 42 .

[0055] The end member 4 may be made of felt or the like.

[0056] By extending the two ends of the blade 2 into the corresponding end parts 4, entanglement between the two ends of the blade 2 and the end parts 4 can be avoided, thereby improving the reliability of the roller brush 10.

[0057] The sweeping machine of the embodiment of the present utility model includes the roller brush 10 described in any one of the above embodiments.

[0058] Wherein, the sweeping machine comprises a main body, and the roller brush 10 is rotatably connected to the main body. When the sweeping machine is working, the roller 1 of the roller brush 10 rotates relative to the main body to clean up the debris on the ground.

[0059] When the sweeper is working, the roller 1 drives the blade 2 and the brush group 3 to rotate. The blade 2 is used to contact the ground and play a supporting role. The bristles of the brush group 3 can pick up hair on the ground, effectively cleaning the hair on the ground and improving the cleaning effect of the sweeper.
