The limiting structure specifically includes a buckle arranged on the roller brush bin and a slot arranged on the body and cooperating with the buckle. The floating range of the roller brush bin is limited by the movement stroke of the buckle in the slot.

[0008] The suction port of the sweeping machine disclosed in the utility model is floatable, so that the sweeping machine can flexibly adjust the height of the suction port to fit the ground in different ground environments, thereby improving the cleaning effect and the user experience.

[0009] A cleaning device according to a Chinese patent (CN202011519230.0) The cleaning device comprises a main body, a driving assembly and a cleaning assembly, wherein the driving assembly comprises a driving device, at least one transmission member and a movable bracket, wherein the driving device is mounted on the main body, the driving device has a driving shaft extending toward the bottom of the main body, the movable bracket is movably connected to the bottom of the main body, the movable bracket is spaced apart from the driving shaft, the movable direction of the movable bracket is substantially perpendicular to the extension direction of the driving shaft, the at least one transmission member connects the movable bracket and the driving shaft, and the driving shaft of the driving device drives the movable bracket to reciprocate back and forth through the at least one transmission member; the cleaning assembly is detachably connected to the movable bracket so that the cleaning assembly reciprocates back and forth with the movable bracket to reciprocately clean the surface to be cleaned;

In the utility model, by setting a rotating part in the limiting groove body on the rear side of the lower shell of the floor brush, when in use, when the large roller rolls on the ground, the connecting shaft moves in a limiting manner in the limiting notch. This limiting movement not only ensures the stability of the connecting shaft, but also makes the entire movement process smoother. At the same time, the second bearing rolls freely on the rolling surface in the limiting groove body, providing necessary support and lubrication for the rotation of the entire floor brush. This rolling reduces friction and resistance, making the floor brush easier to operate.

[0053] See also Figure 1 —5. The utility model provides a technical solution: a large roller assembly of a floor scrubber with an oblique motion function, comprising:

[0054] A floor brush lower shell 1, a limiting groove body 2 is arranged on the rear side of the floor brush lower shell 1, a mounting cavity 3 is arranged in the floor brush lower shell 1, a suction duct 4 and a roller brush assembly 5 are arranged in the mounting cavity 3, a rotating member 6 is arranged in the limiting groove body 2, a large roller 7 is connected to the rotating member 6, and a small roller 8 is arranged on the front side of the bottom of the floor brush lower shell 1;

[0055] The floor brush upper shell 9 is provided with a connecting ear 10 and a limiting arc plate 11 , the connecting ear 10 abuts against the limiting groove body 2 , and the limiting arc plate 11 is located above the roller brush assembly 5 .

[0056] The rotating member 6 includes a first bearing 61, a second bearing 62 and a connecting shaft 63. A screw-connected groove body 12 is arranged in the limiting groove body 2. The first bearing 61 is connected to the screw-connected groove body 12 by a fixing screw 13. One end of the connecting shaft 63 is connected to the first bearing 61. The second bearing 62 is sleeved on the connecting shaft 63. The other end of the connecting shaft 63 is connected to the large roller 7.

[0057] When in use, the connecting shaft moves in a limited position in the limiting notch under the rolling of the large roller, wherein the second bearing rolls on the rolling surface in the limiting groove body, thereby driving the first bearing to rotate on the threaded groove body, wherein the other end of the connecting shaft is connected to the shaft clamping ring on the large roller. This structure can reduce the oblique slippage of the large roller, reduce resistance, and make the floor brush run more flexible.

[0058] The outer side of the limiting groove body 2 is provided with a limiting notch 14, and the inner side of the limiting notch 14 is provided with a rolling surface 15, and the second bearing 62 rolls on the rolling surface 15. The outer side wall of the bottom of the limiting notch 14 is in an arc shape, so as to limit the maximum angle of the oblique movement of the large roller.

[0059] The floor brush lower shell 1 is provided with a plurality of clamping grooves 16, and the floor brush upper shell 9 is provided with a plurality of clamping posts 17, and the plurality of clamping posts 17 and the plurality of clamping grooves 16 match each other, so as to ensure a stable connection between the floor brush upper shell and the floor brush lower shell.

[0061] An abutment platform 18 is disposed in the installation cavity 3 , and an airflow guide device 19 is disposed on the abutment platform 18 . The airflow guide device 19 is communicated with the air suction duct 4 .

[0062] When the floor scrubber starts running, the floor brush rotates to contact the ground and produces a dust suction effect. The airflow guide device is a key component connecting the floor brush and the air inlet duct. It ensures that during the cleaning process, the dust, dirt and other particles rolled up or generated by the floor brush can be effectively sucked in and introduced into the air inlet duct.

[0063] The height of the limiting notch 14 is greater than the diameter of the connecting shaft 63, so as to ensure that the large roller can rotate flexibly and reduce the pressure of the connecting shaft during the rotation process.

The driving motor is connected to the first gear, the first gear and the second gear are engaged with each other, the rotating shaft is connected to the second gear, and both sides of the roller brush are connected to the rotating shaft.

[0065] The circumferential side of the screw-connected groove body 12 is connected to the limiting groove body 2 via connecting ribs.

[0066] Working principle: By setting a rotating part in the limiting groove body on the rear side of the lower shell of the floor brush, when in use, when the large roller rolls on the ground, the connecting shaft moves in a limiting manner in the limiting notch. This limiting movement not only ensures the stability of the connecting shaft, but also makes the entire movement process smoother. At the same time, the second bearing rolls freely on the rolling surface in the limiting groove body, providing the necessary support and lubrication for the rotation of the entire floor brush. This rolling reduces friction and resistance, making the floor brush easier to operate. At the same time, due to the rolling of the second bearing, the first bearing can rotate more smoothly on the screw-connected groove body. This rotation not only improves the cleaning efficiency of the floor brush, but also makes the entire cleaning process easier. In addition, the other end of the connecting shaft is cleverly connected to the shaft clamp on the large roller. This connection method is not only firm and reliable, but also can effectively reduce the oblique slippage of the large roller.
