[0032] Referring to Figure 1 , it is shown that a multi-brush-head linked sweeping robot provided by an embodiment of the application can include a robot body 1, the bottom surface of the robot body 1 is provided with two main brush heads 2, a soft rubber scraping strip 3 and a turnover brush head 4, and a rolling brush 5 is arranged at the center of the bottom surface of the robot body 1;

[0033] The two main brush heads 2 are arranged on one side of the rolling brush 5, the soft rubber scraping strip 3 is arranged on the other side of the rolling brush 5, the turnover brush head 4 is arranged between the soft rubber scraping strip 3 and the rolling brush 5, and the two main brush heads 2 rotate towards the center of the rolling brush 5.

[0034] In the embodiment of the application, in order to solve the problem that the sweeping brush head of the sweeping robot in the prior art is easy to throw the swept dust out of the current sweeping range, a solution is provided by arranging a soft rubber scraping strip and a turnover brush head, specifically, the bottom surface of the robot body 1 is provided with two main brush heads 2, a soft rubber scraping strip 3 and a turnover brush head 4, a rolling brush 5 is arranged at the center of the bottom surface of the robot body 1, the two main brush heads 2 are arranged on one side of the rolling brush 5, the soft rubber scraping strip 3 is arranged on the other side of the rolling brush 5, the turnover brush head 4 is arranged between the soft rubber scraping strip 3 and the rolling brush 5, and the two main brush heads 2 rotate towards the center of the rolling brush 5. By arranging the soft rubber scraping strip 3 and the turnover brush head 4 at the bottom of the robot, the garbage missed from the rolling brush 5 can be gathered by the soft rubber scraping strip 3, and then the garbage is swept into the rolling brush 5 again by the turnover brush head 4, so as to improve the cleaning effect.

[0035] In the following, a multi-brush-head linked sweeping robot in the present exemplary embodiment will be further described.

[0036] Specifically, the multi-brush-head linked sweeping robot can include a robot body 1, the bottom surface of the robot body 1 is provided with two main brush heads 2, a soft rubber scraping strip 3 and a turnover brush head 4, and a rolling brush 5 is arranged at the center of the bottom surface of the robot body 1;

[0037] Two main brush heads 2 are arranged on one side of the roller brush 5, the soft rubber scraping strip 3 is arranged on the other side of the roller brush 5, and the turnover brush head 4 is arranged between the soft rubber scraping strip 3 and the roller brush 5. The two main brush heads 2 rotate towards the center of the roller brush.

[0038] Referring to Figures 1-5 In an embodiment, the two main brush heads 2 are turned from the side of the robot body 1 to the center, so that when the robot body 1 moves to the area of the garbage, the garbage on the periphery is swept inward, and then the garbage in the inner part is rolled into the garbage bag by the roller brush 5.

[0039] Referring to Figures 1-5 The two main brush heads 2 are arranged with a gap between them, which can sweep the garbage towards the roller brush 5, so that the garbage enters the roller brush 5. When the roller brush 5 misses or cannot accommodate the garbage, as the robot body 1 moves, the garbage moves towards the arc-shaped soft rubber scraping strip 3 and gradually accumulates at the soft rubber scraping strip 3, so that the soft rubber scraping strip 3 can temporarily accommodate the garbage. At the same time, the turnover brush head 4 can rotate towards the roller brush 5, and the garbage accumulated at the soft rubber scraping strip 3 can be re-flipped to the roller brush 5, so that the roller brush 5 can collect the remaining garbage, thereby improving the garbage cleaning effect.

[0040] In order to facilitate the accommodation of more missed garbage, the soft rubber scraping strip 3 can be arc-shaped, and the bottom of the soft rubber scraping strip 3 can be provided with a brush, which can sweep the ground as the robot body 1 moves.

[0041] In an embodiment, when the turnover brush head 4 flips the garbage, the garbage may remain on the brush of the turnover brush head 4, so that the brush carries the garbage into the robot body 1.

[0042] In order to be able to clean the garbage remaining on the brush, referring to Figures 1-5 In an embodiment, the bottom surface of the robot body 1 is provided with a turnover groove 6, the turnover brush head 4 is arranged in the turnover groove 6 and rotates in the turnover groove 6, the width of the turnover groove 6 is a first size value, the length of the rotating head of the turnover brush head 4 is a second size value, and the length of the brush of the turnover brush head 4 is a third size value, wherein the first size value is greater than the second size value, and the first size value is less than the sum of the second size value and the third size value.

[0043] The first dimension value of the width of the turnover groove 6 is greater than the second dimension value of the length of the turnover head 4, so that the turnover head 4 can continuously rotate in the turnover groove 6. The first dimension value of the width of the turnover groove 6 is less than the sum of the second dimension value of the length of the turnover head 4 and the third dimension value of the length of the brush of the turnover head 4, so that the brush needs to touch the side of the turnover groove 6 when it is turned over from the outside into the turnover groove 6 each time. The bristles on the brush are relatively soft and will be deformed and curled after touching the side of the turnover groove 6, so as to enter the turnover groove 6. In the process of deformation and curling, the side of the turnover groove 6 scrapes off the garbage or hair remaining on the surface of the brush, thereby achieving the effect of cleaning the garbage remaining on the turnover brush.

[0044] Similarly, when the turnover head 4 rotates from the turnover groove 6 to the outside, the brush can also touch the side of the turnover groove 6, thereby being deformed and curled, and then extending out of the turnover groove 6.

[0045] Such repeated turnover can allow the side of the turnover groove 6 to clean the garbage remaining on the turnover head 4.

[0046] It should be noted that, Figures 3-5 In the figure, the black part is the brush.

[0047] In an optional embodiment, in order to further clean the garbage on the turnover head 4, an arc-shaped baffle can be arranged on the side of the turnover groove 6, and a plurality of hooks are arranged on the baffle to clean the garbage on the brush.

[0048] In a specific implementation, the turnover head 4 and the roller brush 5 can be connected to the same motor, so that the motor drives the turnover head 4 and the roller brush 5 to work at the same time. The specific connection mode is that the turnover head 4 and the roller brush 5 are connected to the internal motor through chains respectively.

[0049] Referring to Figures 1-5 , in order to improve the efficiency of cleaning garbage, in an embodiment, the turnover head is provided with two.

[0050] Specifically, the two turnover heads are arranged at an angle, and the angle can be directed to the center of the roller brush 5, so that the garbage can be turned over in the direction of the roller brush 5, and the garbage can be swept into the roller brush 5.

[0051] In order to place the roller brush 5, referring to Figures 1-5 , in an embodiment, the center of the bottom surface of the robot body 1 is provided with a receiving groove 7, the roller brush 5 is arranged in the receiving groove 7, and the roller brush 5 is provided with a gap from the ground.

[0052] The gap between the roller brush 5 and the ground can avoid the direct contact between the roller brush 5 and the ground. The size of the gap can be adjusted according to actual needs, and can be 0.5 cm. If the robot mainly cleans hair, the gap distance can be appropriately reduced.

[0053] In order to deal with the cleaned garbage, referring to Figures 1-5 In an embodiment, the top surface of the accommodating groove 7 is provided with a fan 8, and the inside of the robot body 1 is provided with a dust collecting box 9, and the other end of the fan 8 is connected with the dust collecting box 9.

[0054] In order to improve the sweeping efficiency of the robot and facilitate the walking of the robot, in an embodiment, the bottom surface of the robot body 1 is provided with a roller 10.
