[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-7 This utility model provides a technical solution:

[0024] A sweeper includes a sweeper body 1. A miniature electric push rod 2 is mounted on the bottom surface of the sweeper body 1. The miniature electric push rod 2 allows for easy adjustment of the position of circular brooms 8, facilitating their contact with or detachment from the ground. Three circular brooms 8 are arranged in an equilateral triangle to clean areas where two brooms 8 meet, preventing missed areas and ensuring a clean surface. A connecting plate 3 is fixedly connected to the movable end of the miniature electric push rod 2 for connecting the circular brooms 8. A movable shaft 7 is rotatably mounted on the connecting plate 3, and an annular slider is fixedly mounted on the outer wall of the movable shaft 7. An annular groove is formed on the connecting plate 3 to cooperate with the annular slider. The interaction between the annular slider and the annular groove facilitates the rotation of the movable shaft 7 and allows the circular brooms to move when the connecting plate 3 moves up and down. 8. The movable shaft 7 moves up and down; a mounting plate 4 is fixedly connected to the bottom of the movable shaft 7, and a round broom 8 is mounted on the bottom surface of the mounting plate 4 through a connecting component. The use of the connecting component facilitates the installation of the round broom 8, making the operation simple and convenient, and improving the installation efficiency of the round broom 8. Conversely, it also facilitates the disassembly efficiency of the round broom 8, thus facilitating the replacement of the round broom 8; a hollow shaft 5 is slidably provided on the top of the movable shaft 7, and the top of the hollow shaft 5 is connected to the power source in the sweeper body 1. The power source of the sweeper body 1 includes a drive motor (not shown in the figure) and a connecting shaft (not shown in the figure) set on the output shaft of the drive motor. A drive gear (not shown in the figure) is fixedly connected to the connecting shaft, and a driven gear (not shown in the figure) meshing with the drive gear is fixedly connected to the outer wall of the hollow shaft 5, so as to facilitate the rotation of the round broom 8, thereby facilitating the cleaning of the ground.

[0025] In this utility model, the connecting assembly includes a sleeve 13 disposed in the middle of the bottom surface of the mounting plate 4. A connecting post 9 is slidably disposed inside the sleeve 13. The bottom of the connecting post 9 is fixedly connected to the circular broom 8. A locking block 10 is symmetrically disposed on the outer wall of the connecting post 9. A strip groove 15 that cooperates with the locking block 10 is symmetrically disposed on the inner wall of the sleeve 13. An arc groove 17 that cooperates with the locking block 10 is symmetrically disposed at the bottom of the strip groove 15. A locking groove 14 that cooperates with the locking block 10 is disposed at the end of the arc groove 17. An arc cavity 16 is disposed at the bottom of the arc groove 17. A lifting member is disposed inside the arc cavity 16. By using the lifting member, it is easy to lift the locking block 10, so that the locking block 10 is stably locked in the locking groove 14, thereby improving the stability of the installation of the circular broom 8. A circular groove 18 that cooperates with the connecting post 9 is disposed on the bottom surface of the mounting plate 4, and the circular groove 18 communicates with the locking groove 14.

[0026] In this utility model, the lifting component includes a top block 11 slidably disposed in the arc-shaped cavity 16, and a compression spring 12 is provided between the top block 11 and the arc-shaped cavity 16. The elastic force of the compression spring 12 is greater than the weight of the circular broom 8, so as to facilitate the locking block 10 in the slot 14.

[0027] In this invention, the opposing surfaces of the top block 11 and the locking block 10 are both arc-shaped surfaces, which makes it easy for the top block 11 to be pushed into the arc-shaped cavity 16 when rotating, thereby making it easy for the locking block 10 to pass through the top block 11 and to lift the locking block 10.

[0028] In this utility model, limiting strips 6 are symmetrically fixed to the outer wall of the movable shaft 7, and limiting grooves are formed on the inner wall of the hollow shaft 5 in conjunction with the limiting strips 6. Through the mutual cooperation of the limiting strips 6 and the limiting grooves, the hollow shaft 5 can drive the movable shaft 7 to rotate when it rotates, thereby facilitating the rotation of the circular broom 8.

[0029] Working principle: When using this utility model to clean the ground, first open the mini electric push rod 2. The movable end of the mini electric push rod 2 extends and drives the connecting plate 3 to move downward, which in turn drives each movable shaft 7 to move downward, thereby driving the mounting plate 4 to move downward, and further driving the circular broom 8 to move downward, so that the circular broom 8 contacts the ground. Then, start the drive motor in the sweeper body 1 to make each hollow shaft 5 rotate, which in turn drives the movable shaft 7 to rotate, thereby driving the mounting plate 4 and the circular broom 8 to rotate, thus cleaning the ground.

[0030] When it is necessary to replace the round broom 8, first disassemble the round broom 8. Specifically, first pull the round broom 8 down to disengage the locking block 10 from the locking groove 14, then rotate the round broom 8 to rotate the locking block 10 into the strip groove 15 to release the fixation of the round broom 8, and then remove the round broom 8.

[0031] When installing the circular broom 8, insert the connecting post 9 on the circular broom 8 into the sleeve 13, and let the locking block 10 enter along the strip groove 15. When the locking block 10 moves to the bottom of the strip groove 15, rotate the circular broom 8 to move the locking block 10 into the arc cavity 16. When the locking block 10 enters the arc cavity 16, since the opposing surfaces of the locking block 10 and the top block 11 are both arc-shaped, the top block 11 moves into the arc cavity 16. When the locking block 10 moves to the bottom of the slot 14, the locking block 10 is lifted by the compression spring 12, so that the locking block 10 is locked in the slot 14.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
