[0023] Example 1

[0024] Please refer to Figures 1-6The small, environmentally friendly, unmanned sweeping robot shown includes an outer shell 1. Rollers 11 are installed at the bottom of the outer shell 1. A dust inlet chamber 2 is opened at the bottom of the outer shell 1. A suction pipe 21 is connected to the top of the dust inlet chamber 2. The other end of the suction pipe 21 is connected to a suction component installed inside the outer shell 1. A sweeping roller 22 is rotatably connected between the front and rear inner walls of the dust inlet chamber 2. The sweeping roller 22 is connected to a drive component installed inside the outer shell 1. Two mounting boxes 3 are symmetrically connected to the left and right inner walls of the dust inlet chamber 2. Two sets of first cutting blades 4 are connected to the left and right inner sides of the two mounting boxes 3. Multiple first cutting blades 4 in each set are equidistantly distributed along the axial direction of the sweeping roller 22, and the blade part of the first cutting blade 4 leaves a gap of no more than one millimeter between it and the outer peripheral surface of the sweeping roller 22.

[0025] refer to Figures 2-4 Two replacement assemblies 5 are symmetrically connected within the inner cavities of the two mounting boxes 3. Each replacement assembly 5 includes two sets of second cutting blades 51 symmetrically connected within the inner cavities of the two mounting boxes 3. Multiple second cutting blades 51 in each set are equidistantly distributed along the axis of the cleaning roller 22, with a gap of not less than one millimeter between the cutting edge of each second cutting blade 51 and the outer circumferential surface of the cleaning roller 22. A set of first cutting blades 4 and a set of second cutting blades 51 on the same side are staggered. The replacement assembly 5 also includes two sets of through cavities 52 symmetrically opened on the adjacent sides of the two mounting boxes 3. Multiple through cavities 52 in each set are symmetrically connected along the axis of the cleaning roller 22. The cleaning roller 22 is equidistantly distributed along its length. The number of passage cavities 52 in each group is equal to the sum of the number of a first cutting blade 4 and a second cutting blade 51. Each group of multiple passage cavities 52 is aligned with a first cutting blade 4 and a second cutting blade 51 on the same side. The rotation assembly 5 also includes a rotation mechanism 53 connected in the inner cavity of the mounting box 3. A first cutting blade 4 and a second cutting blade 51 on the same side are both connected to the rotation mechanism 53. The rotation mechanism 53 is used to push a first cutting blade 4 and a second cutting blade 51 on the same side to alternately press against the outer circumferential surface of the cleaning roller 22.

[0026] Specifically, the alternation mechanism 53 can push a set of first cutting blades 4 and second cutting blades 51 on the same side to alternately press against the outer circumference of the sweeping roller 22. This can shorten the cutting time of the first cutting blades 4 and second cutting blades 51, thereby effectively reducing the frequency of replacing the first cutting blades 4 and second cutting blades 51 and improving the practicality and convenience of the sweeping robot.

[0027] refer to Figures 3-6The rotating mechanism 53 includes a rotating shaft 531 rotatably connected between the front and rear inner walls of the mounting box 3. A plurality of first cutting blades 4 are equidistantly fixed to the outer circumferential surface of the rotating shaft 531 along the axial direction of the cleaning roller 22. Two fixing rings 532 are symmetrically fixed to the outer circumferential surface of the rotating shaft 531. Two first torsion springs 533 are symmetrically fixed between the sides of the two fixing rings 532 that are far apart and the front and rear inner walls of the mounting box 3. A plurality of rotating rings 531 are equidistantly rotatably sleeved on the outer circumferential surface of the rotating shaft 531 along the axis of rotation of the rotating shaft 531. 34. A group of multiple second cutting blades 51 are fixedly connected to the outer circumferential surface of multiple rotating rings 534. The bottom of the multiple rotating rings 534 is fixedly connected to the same connecting plate 535. The rotation mechanism 53 also includes two sets of drive mechanisms 536 connected in the inner cavity of the mounting box 3. The two sets of drive mechanisms 536 are used to drive the rotating shaft 531 and the connecting plate 535 to rotate clockwise or counterclockwise respectively. The two sets of drive mechanisms 536 drive a group of first cutting blades 4 and a group of second cutting blades 51 on the same side to swing alternately and press against the outer circumferential surface of the cleaning roller 22.

[0028] Specifically, by driving a set of first cutting blades 4 and a set of second cutting blades 51 on the same side to swing alternately and press against the outer circumferential surface of the sweeping roller 22, the first cutting blades 4 and the second cutting blades 51 can be stably driven to alternately press against the outer circumferential surface of the sweeping roller 22, ensuring that the alternation operation of the first cutting blades 4 and the second cutting blades 51 can be carried out smoothly, thus improving the reliability and stability of the sweeping robot.

[0029] refer to Figures 4-6 The drive mechanism 536 includes a lever 5361 fixedly connected to the bottom of the connecting plate 535 or the bottom of the fixing ring 532. An elastic element 5362 is fixedly connected between the side of the lever 5361 and the inner wall of the left or right side of the inner cavity of the mounting box 3. The drive mechanism 536 also includes an electric push rod 5363 symmetrically fixedly connected to the bottom wall of the inner cavity of the mounting box 3. A push plate 5364 is fixedly connected to the output end of the electric push rod 5363, and the push plate 5364 and the side of the lever 5361 are pressed together. The lever 5361 is located between the push plate 5364 and the elastic element 5362.

[0030] Specifically, the electric push rod 5363 is activated to extend and retract, thereby driving the push plate 5364 to move left and right. The push plate 5364, in conjunction with the elastic element 5362, drives the paddle plate 5361 to swing clockwise or counterclockwise, thereby enabling a set of second cutting blades 51 or a set of first cutting blades 4 to swing clockwise or counterclockwise through the connecting plate 535 or the fixing ring 532 to approach or move away from the outer circumference of the cleaning roller 22.

[0031] refer to Figures 1-3 A quick-release assembly 6 is connected to the inner wall of the dust inlet chamber 2, and the quick-release assembly 6 is connected to two mounting boxes 3.

[0032] The quick-release assembly 6 includes two pairs of iron blocks 61 symmetrically fixedly connected to the inner walls of the dust inlet chamber 2 on the left and right sides. The quick-release assembly 6 also includes two rectangular slots 62 symmetrically opened on the top of the two mounting boxes 3. Magnetic plates are embedded in the inner walls of the two rectangular slots 62. The iron blocks 61 can be inserted into the rectangular slots 62 and attracted to the magnetic plates. The quick-release assembly 6 also includes two pairs of damping rotating rods 63 symmetrically fixedly connected to the bottom of the two pairs of iron blocks 61. Two pairs of baffles 64 are symmetrically fixedly connected to the bottom ends of the two pairs of damping rotating rods 63. The top surfaces of the two pairs of baffles 64 are pressed tightly against the bottom surfaces of the two mounting boxes 3. When disassembling the mounting box 3, it is only necessary to rotate the baffles 64 until they separate from the bottom surface of the mounting box 3, and then pull the mounting box 3 downwards until it separates from the iron blocks 61 to complete the disassembly work. This improves the convenience and efficiency of disassembling and installing the mounting box 3, the first cutting blade 4, and the second cutting blade 51.

[0033] Specifically, this design allows the mounting box 3 and its first cutting blade 4 and second cutting blade 51 to be easily disassembled or installed onto the outer casing 1, facilitating the replacement and maintenance of the first cutting blade 4 and second cutting blade 51 by staff, thus improving the convenience of the sweeping robot.

[0034] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
