Referring to fig. 3 and 4, in order to improve the production and assembly efficiency of the roll brush, the supporting rubber 200 includes at least two supporting members rotationally symmetrical on the surface of the main shaft 300 along the circumferential direction of the main shaft 300, at least two of the supporting members respectively contact with adjacent supporting members along the circumferential direction of the main shaft 300, specifically, when the supporting rubber 200 and the main shaft 300 are connected, by surrounding the at least two supporting members on the outer circumferential surface of the main shaft 300, when the supporting members are surrounded, at least two of the supporting members respectively contact with adjacent supporting members along the circumferential direction of the main shaft 300 to form an integral supporting rubber 200, and are fixed by sleeving the rubber body 100, thereby reducing the assembly time of the conventional supporting structure of the main shaft 300, saving more effort, and reducing the fatigue degree of workers.

Referring to fig. 4, further, at least two of the supporting members include a first supporting member 210 and a second supporting member 220 symmetrically disposed on both sides of the outer circumference of the spindle 300, the cavities 230 are formed on the first supporting member 210 and the second supporting member 220, a plurality of supporting ribs 240 are disposed in the cavities 230 of the first supporting member 210 and the second supporting member 220 along the axial direction of the spindle 300, and the supporting ribs 240 are provided with notches 241 contacting at least part of the outer circumference of the spindle 300, specifically, the first supporting member 210 and the second supporting member 220 symmetrically enclose the spindle 300 to form an integral supporting glue member 200, so that the number of supporting members is reduced, the picking up and enclosing alignment of workers are facilitated, the assembly efficiency is further improved, and the notches 241 of the supporting ribs 240 disposed on the first supporting member 210 and the second supporting member 220 are matched to form the same contour as the outer circumference of the spindle 300, so that the supporting ribs 240 closely contact the surface of the spindle 300, and the connection degree of the supporting glue member 200 and the spindle 300 is improved.

Referring to fig. 3 and 4, in order to prevent the supporting rubber member 200 from being uncontrollably displaced on the main shaft 300 along the axial direction thereof when the roll brush is rotated, the main shaft 300 includes: a main body 310, wherein the support is sleeved on the surface of the main body 310; the limiting parts 320 are respectively arranged at two axial ends of the main body part 310, and the outer diameter of the limiting parts 320 is larger than that of the main body part 310; wherein, the support member contacts with one side of the limiting part 320 near the main body part 310 along the axial end of the main body part 310, the limiting parts 320 arranged at the two axial ends of the main body part 310 play a role in limiting the support rubber member 200, and the time for calibrating the support rubber member 200 when the worker installs is further shortened during the installation, thereby improving the production efficiency.

Referring to fig. 1 and 2, in order to improve the cleaning ability of the rolling brush of the present utility model when contacting the cleaning surface, the rubber body 100 includes: a cylinder 110, wherein the cylinder 110 is sleeved on the outer surface of the main shaft 300 along the axial direction of the main shaft 300, and the cylinder 110 is cylindrical; a plurality of blades spirally connected to an outer circumferential surface of the cylinder 110 in an axial direction of the cylinder 110, and extending from one end to the other end of the cylinder 110; wherein the blade has a cleaning surface 121 for cleaning, and the blade is inclined toward a surface away from the cleaning surface 121 in a circumferential cross section of the cylinder 110. Specifically, when the main shaft 300 drives the cylinder 110 and the supporting rubber 200 to rotate, the blades guide dust, hair and other garbage on the cleaning surface to move along the spiral blades towards the end of the cylinder 110, so that dust is absorbed and collected by a dust collection port (not shown in the drawing) of the cleaning device, and the overall design of the blades effectively enhances the water sweeping capability of the rubber body 100.

In actual use, the blade drives the supporting glue piece 200 and the cylinder 110 to rotate through the main shaft 300 to treat the garbage on the cleaning surface, in this process, the rolling brush rotates along the direction opposite to the inclined direction of the blade (namely along the arrow direction a in fig. 1 and 2), the cleaning surface 121 of the blade can directly contact with the cleaning surface with the garbage, and the garbage on the cleaning surface is guided to walk along the end part of the blade towards the rolling brush until the garbage is intensively adsorbed and collected by the dust collection opening of the cleaning device, the contact area between the cleaning surface 121 of the blade and the cleaning surface is enlarged, and the cleaning efficiency is effectively improved.

Further, the blades include a first blade 120 and a second blade 130, and the first blade 120 and the second blade 130 are spaced apart; on the circumferential cross section of the cylinder 110, the length of the second blade 130 is greater than that of the first blade 120, the lengths of the first blade 120 and the second blade 130 are different, in the rotating process of the cylinder 110, the contact degree of the cleaning surface of the first blade 120 and the cleaning surface of the second blade 130 and the ground are inconsistent, noise generated in the using process of the whole rolling brush is reduced, and the using experience of a user is improved.

In the process of rotating the roller brush, referring to fig. 1 and 2, since the first blade 120 and the second blade 130 have a length difference, the contact ranges of the cleaning surfaces 121 of the first blade 120 and the second blade 130 and the cleaning surface are inconsistent, and the generated noise of the cleaning surfaces is inconsistent, specifically, the noise generated by the shorter first blade 120 and the ground contact is smaller, and the first blade 120 and the second blade 130 with different lengths are arranged on the surface of the cylinder 110, so that the noise generated when the roller brush processes garbage on the cleaning surface is reduced, and the use feeling of a user is improved.

In addition, the rubber body 100 also vibrates the first blade 120 and the second blade 130 during rotation, and the shorter first blade 120 vibrates less than the longer first blade 120.

In contrast, the cleaning effect of the second blade 130 is better than that of the first blade 120, and if a shorter blade is used for reducing noise, the cleaning effect is sacrificed, so that the rubber body 100 according to the embodiment of the present utility model sets two types of blades with different lengths on the surface of the cylinder 110, and on the circumferential cross section of the cylinder 110, the thickness of the first blade 120 is greater than that of the second blade 130, and by the thickened first blade 120, the first blade 120 can be ensured to be fully contacted with the cleaning surface, and the noise caused by the rolling brush in the rotation process can be reduced while the cleaning effect on the cleaning surface is ensured.

Further, the distances between the adjacent first and second blades 120 and 130 are equal. The first blades 120 and the second blades 130 are arranged at intervals, the arrangement modes of the equal arrangement distances enable the whole rolling brush structure to tend to be stable in the rotating process, vibration generated in the rotating process is reduced, accordingly the whole cleaning device works more smoothly, and cleaning effect is improved.

In addition, the stable operation state, in combination with the supporting rubber member 200 having the cavity 230, can minimize the operation vibration of the entire cleaning apparatus, thereby effectively reducing the noise generated from the cleaning apparatus in the actual operation.

Because the length of the second blade 130 is greater than that of the first blade 120, when the cleaning surface 121 of the second blade 130 contacts with the cleaning surface, larger deformation is required to be generated to not block the contact between the first blade 120 and the cleaning surface, and because the contact area of the second blade 130 with the cleaning surface is greater than that of the first blade 120 in use, the second blade 130 is more easily worn and irregularly deformed away from the radial outer side of the elastic cylinder 110, therefore, the reinforcing rib 131 is arranged on the other surface of the second blade 130 facing away from the cleaning surface 121 along the extending direction of the second blade 130 at the radial outer side of the cylinder 110, and the reinforcing rib 131 effectively enhances the wear resistance and deformation resistance of the second blade 130, so that the cleaning surface 121 of the second blade 130 can be kept in full contact with the cleaning surface.

Referring to fig. 2 to 4, one end of the spindle 300 opposite to the output end of the cleaning device is not rotatably connected with the cleaning device, the spindle 300 further includes a driving portion 330 disposed at one end of one of the limiting portions 320 away from the main body portion 310, and the driving portion 330 is in anti-rotation fit with the output end of the cleaning device motor, so that the output end of the cleaning device motor drives the rolling brush to rotate, and cleaning is performed.

And the ring groove 420 and the elastic clamping block 630 cooperate to realize that the bearing 500 and the bearing seat 600 are kept rotatably connected to the rotating shaft 400.
