[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: a sweeping robot includes a sweeping robot body 1. An electric push rod 5 is fixedly connected to the top surface of the inner cavity of the sweeping robot body 1, and a sliding plate 6 is fixedly connected to the bottom end of the output end of the electric push rod 5. When the electric push rod 5 is activated, the sliding plate 6 can be pushed up and down.

[0027] The bottom surface of one end of the sliding plate 6 is rotatably connected to the first rotating shaft 7, and the bottom surface of the other end of the sliding plate 6 is rotatably connected to the second rotating shaft 12. The first rotating shaft 7 and the second rotating shaft 12 are both arranged vertically.

[0028] Grooves are formed at both ends of the bottom surface of the sliding plate 6. Rotary disks are fixedly connected to the tops of the first rotating shaft 7 and the second rotating shaft 12. The rotating disks are rotatably connected to the corresponding grooves. The grooves position the first rotating shaft 7 and the second rotating shaft 12 on the sliding plate 6, allowing them to move up and down with the sliding plate 6.

[0029] The bottoms of the first rotating shaft 7 and the second rotating shaft 12 rotate and penetrate the bottom surface of the sweeping robot body 1 , and a plurality of brushes are provided on the bottoms of the first rotating shaft 7 and the second rotating shaft 12 .

[0030] The bottom end of the second rotating shaft 12 is coaxially fixedly connected to the first cleaning brush 2. Several brushes located at the bottom of the second rotating shaft 12 are circumferentially distributed and fixedly connected to the bottom surface of the first cleaning brush 2. The bottom end of the first rotating shaft 7 is coaxially fixedly connected to the second cleaning brush 4. Several brushes located at the bottom of the first rotating shaft 7 are circumferentially distributed and fixedly connected to the bottom surface of the second cleaning brush 4.

[0031] The hair brushes are all tilted. The hair brushes located at the bottom surface of the first cleaning brush 2 gradually tilt toward the outside of the first cleaning brush 2 from one end near the middle of the first cleaning brush 2 to the other end. The first cleaning brush 2 and the hair brush form an umbrella-shaped structure.

[0032] The hairbrush positioned at the second cleaning brush 4 bottom surfaces gradually tilts toward the outside of the second cleaning brush 4 from one end near the second cleaning brush 4 middle parts to the other end. The second cleaning brush 4 and the hairbrush form an umbrella-shaped structure.

[0033] A driving assembly is provided inside the main body 1 of the sweeping robot, and the driving assembly drives the first rotating shaft 7 and the second rotating shaft 12 to rotate synchronously.

[0034] The drive assembly includes a motor 11. A fixed plate 9 is fixedly connected to the interior of the robot vacuum's main body 1. The fixed plate 9 is located below the sliding plate 6, with the fixed plate 9 and sliding plate 6 aligned vertically. Both the first rotating shaft 7 and the second rotating shaft 12 slide through the fixed plate 9. A fourth gear 14 is mounted vertically on the second rotating shaft 12, while a first gear 8 is mounted vertically on the first rotating shaft 7.

[0035] Two retaining rings 16 are fixedly attached to the top of the fixing plate 9. Restricting slots are defined on the bottom surfaces of the first gear 8 and the fourth gear 14, and the retaining rings 16 are rotatably connected to the corresponding retaining slots. This positions the first gear 8 and the fourth gear 14 on the fixing plate 9, ensuring that the first gear 8 and the fourth gear 14 can only rotate on the top of the fixing plate 9.

[0036] Motor 11 is fixedly connected to the bottom surface of fixed plate 9, and its output shaft rotates through fixed plate 9. A third gear 13 is fixedly mounted on the output shaft of motor 11 and meshes with fourth gear 14. A second gear 10 is rotatably connected to the top of fixed plate 9 and meshes with first gear 8 and third gear 13. Motor 11 drives third gear 13 to rotate, which in turn drives fourth gear 14 and second gear 10, which in turn drives first gear 8. This results in synchronous rotation of first gear 8 and fourth gear 14, but in opposite directions.

[0037] The outer surfaces of the first and second rotating shafts 7 and 12 are symmetrically defined with vertically arranged slots 15. Two protrusions are fixedly attached to the inner walls of the first and fourth gears 8 and 14, respectively slidingly engaging corresponding slots 15. When the first gear 8 rotates, the protrusions drive the first rotating shaft 7 along with it. Similarly, the fourth gear 14 drives the second rotating shaft 12 along with it. As a result, the first and second rotating shafts 7 and 12 rotate synchronously but in opposite directions.

[0038] The vacuum cleaner body 3 is fixedly mounted on the bottom surface of the robot vacuuming robot body 1. The vacuum cleaner body 3 rotates at high speeds through its internal motor, which generates negative pressure through its fan blades. This negative pressure creates a difference with the external atmospheric pressure, drawing ambient air and dust into the body 3. The inhaled air is then filtered through a filter, removing large particles and dust, while clean air is exhausted from the body 3. Dust and impurities are collected in a dust bag or dust container. The vacuum cleaner body 3 is an existing product.

[0039] Working principle:

[0040] When the robot vacuum cleaner body 1 is used for cleaning, the electric push rod 5 is started to push the sliding plate 6 downward, thereby driving the first rotating shaft 7 and the second rotating shaft 12 to move downward.

[0041] The first rotating shaft 7 slides downward through the first gear 8, and the second rotating shaft 12 slides downward through the 4th gear 14. The first cleaning brush 2 and the second cleaning brush 4 are moved downward so that the hair brush contacts the ground.

[0042] When the motor 11 is started, the output shaft of the motor 11 rotates the third gear 13. The third gear 13 rotates the fourth gear 14, which in turn rotates the second rotating shaft 12. The top end of the second rotating shaft 12 rotates on the sliding plate 6, and the second rotating shaft 12 rotates the first cleaning brush 2.

[0043] The third gear 13 will simultaneously drive the second gear 10 to rotate, and the second gear 10 will drive the first gear 8 to rotate, so that the first rotating shaft 7 and the second cleaning brush 4 will rotate.

[0044] The first cleaning brush 2 and the second cleaning brush 4 are rotated synchronously and in opposite directions, so that the brushes clean the ground.

[0045] During cleaning, the electric push rod 5 is activated, pushing the sliding plate 6 downward, causing the first rotating shaft 7 and the second rotating shaft 12 to move downward. The downward movement of the first and second cleaning brushes 2 and 4 presses the brushes downward, increasing their tilt. This not only increases the cleaning area but also improves the contact force between the brushes and the ground, enhancing the cleaning effect. The vacuum cleaner body 3 then sucks away the cleaned debris.

[0046] After cleaning is complete, the electric push rod 5 is activated, pulling the sliding plate 6 upward. This causes the first rotating shaft 7 and the second rotating shaft 12 to move upward, driving the first cleaning brush 2 and the second cleaning brush 4 to move upward. This lifts the brushes off the ground, preventing the brushes from contacting the ground during movement of the robot vacuum cleaner body 1. This prevents the brushes from constantly contacting the ground, reduces wear on the brushes, and increases their service life.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
