[0001] This utility model relates to the field of sweeping machine technology, and in particular to a sweeping machine circular brush cloth. Background Technology

[0002] Household robotic vacuum cleaners are cordless, primarily disc-shaped, and operate using rechargeable batteries. They are controlled via remote control or a control panel on the machine. To clean the floor more thoroughly, robotic vacuum cleaners typically have one to three cleaning tools on their underside. One of these tools is called a "circular brush," which usually has an independent motor that rotates it to clean the floor in a circular motion.

[0003] When a circular brush needs cleaning after long-term use, it needs to be removed from the bottom of the sweeper for cleaning or replacement. The existing circular brush installation method is a snap-fit, which is convenient and can be done by simply pressing it down. However, with long-term use, the protruding points used for connection will wear down, resulting in a poor connection effect. Therefore, we propose a circular brush cloth for sweepers.

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a circular brush cloth for a sweeper, which makes the connection between the circular brush cloth and the insertion slot more stable and longer in use, without adding extra operation steps. It effectively improves the efficiency of replacing the circular brush cloth and the stability of installation, making it easier and more convenient for users to clean the circular brush cloth and providing a better user experience.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a circular brush cloth for a sweeper, comprising a sweeper and a connecting mechanism. The connecting mechanism includes an insertion groove, which is formed on the bottom surface of the sweeper. A connecting column is rotatably connected to the inner side of the insertion groove. A positioning block and a first magnetic sheet are provided on the top end face of the connecting column. A circular brush cloth is movably connected to the bottom of the sweeper. A connecting column is provided at the bottom end of the circular brush cloth. One end of the connecting column is movably inserted into the inner side of the insertion groove, and a positioning groove and a second magnetic sheet are formed on the bottom end face of the connecting column. The positioning groove is movably sleeved on the outer side of the positioning block. The second magnetic sheet and the first magnetic sheet are magnetically connected.

[0006] As a preferred technical solution of this utility model, the positioning block has symmetrically opened limit grooves on both sides, and the inner side of the positioning groove is symmetrically provided with limit sliders, and the two limit sliders are respectively movably connected to the inner side of the two limit grooves.

[0007] As a preferred technical solution of this utility model, the bottom end of the inner side of the limiting outer groove and the top end of the limiting slider are respectively provided with a first magnetic point and a second magnetic point, and the first magnetic point and the second magnetic point are magnetically connected.

[0008] As a preferred technical solution of this utility model, the first magnetic sheet and the second magnetic sheet are mirror images of each other with the center point of the top end face of the positioning block and the center point of the inner side of the positioning groove as the axis, and the positions of the two first magnetic sheets and the two second magnetic sheets are correspondingly arranged.

[0009] As a preferred technical solution of this utility model, it also includes a replacement mechanism, which includes an inner connecting ring.

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example 1:

[0021] like Figures 1-3 As shown, a circular brush cloth for a sweeper includes a sweeper 1 and a connecting mechanism. The connecting mechanism includes an insertion groove 11, which is formed on the bottom surface of the sweeper 1. A connecting column 12 is rotatably connected to the inside of the insertion groove 11. A positioning block 13 and a first magnetic sheet 16 are provided on the top end face of the connecting column 12. A circular brush cloth 2 is movably connected to the bottom of the sweeper 1. A connecting column 21 is provided at the bottom of the circular brush cloth 2. One end of the connecting column 21 is movably inserted into the inside of the insertion groove 11, and a positioning groove 2 is formed on the bottom end face of the connecting column 21. 2. The second magnetic sheet 25 and the first magnetic sheet 16 are movably sleeved on the outside of the positioning block 13. The second magnetic sheet 25 and the first magnetic sheet 16 are magnetically connected. The positioning block 13 has symmetrically opened limit grooves 14 on both sides. The inner side of the positioning groove 22 is symmetrically provided with limit sliders 23. The two limit sliders 23 are movably connected to the inner side of the two limit grooves 14. The bottom end of the inner side of the limit groove 14 and the top end of the limit slider 23 are respectively provided with a first magnetic point 15 and a second magnetic point 24. The first magnetic point 15 and the second magnetic point 24 are magnetically connected.

[0022] Household robotic vacuum cleaners are cordless, primarily disc-shaped, and operate using rechargeable batteries. They are controlled via remote control or a control panel on the machine. To clean the floor more thoroughly, robotic vacuum cleaners typically have one to three cleaning tools on their underside. One of these tools is called a "circular brush," which usually has an independent motor that rotates it to clean the floor in a circular motion.

[0023] Generally, when the round brush needs to be cleaned after long-term use, it needs to be removed from the bottom of the sweeper for cleaning or replacement. The existing round brush is installed by snap-fit, which is convenient to operate by simply pressing it down. However, with long-term use, the protruding points used for connection will wear down, resulting in a poor connection effect.

[0024] When it is necessary to replace the circular brush 2, first pull the used circular brush 2 outward with force. The connection between the second magnetic piece 25 and the first magnetic piece 16 will be broken. At the same time, the positioning block 13 will leave the positioning groove 22, and the circular brush 2 can be removed. Then take the new circular brush 2, align the connecting post 21 with the inside of the insertion groove 11, and push it in after aligning the positioning groove 22 and the positioning block 13. The positioning block 13 will enter the inside of the positioning groove 22, and the limiting slider 23 will also enter the inside of the limiting outer groove 14 and slide all the way until it touches the bottom. The second magnetic point 24 and the first magnetic point 15, and the first magnetic piece 16 and the second magnetic piece 25 will contact each other and establish a magnetic connection. The circular brush 2 can then be successfully installed at the bottom of the sweeper 1.

[0025] This makes the connection between the circular brush 2 and the insertion slot 11 more stable and longer-lasting without adding extra steps. It effectively improves the efficiency of replacing the circular brush 2 and the stability of its installation, making it easier and more convenient for users to clean the circular brush 2 and providing a better user experience.

[0026] In other embodiments, this embodiment discloses, please refer to Figures 1-3 As shown, the first magnetic piece 16 and the second magnetic piece 25 are mirror images of each other with the center point of the top end face of the positioning block 13 and the center point of the inner side of the positioning groove 22 as axes, and the positions of the two first magnetic pieces 16 and the two second magnetic pieces 25 are correspondingly set. Through this design, the number of the first magnetic pieces 16 and the second magnetic pieces 25 can be increased, which makes the connection between the circular brush 2 and the sweeper 1 more stable.

[0027] Example 2:

[0028] In other embodiments, this embodiment discloses, please refer to Figure 1 , Figure 4 As shown, it also includes a replacement mechanism, which includes an inner connecting ring 3. The inner connecting ring 3 is located at the connection between the circular brush cloth 2 and the connecting post 21. A semi-open connecting groove 31 is provided on the inner side of the inner connecting ring 3. A limiting inner groove 32 is provided on the inner side of the semi-open connecting groove 31. An L-shaped connecting rod 26 is provided on the outer side of the connecting post 21. The L-shaped connecting rod 26 is movably connected to the inner side of the semi-open connecting groove 31 and one end is inserted into the innermost side of the limiting inner groove 32. A positioning screw assembly 27 is provided at the connection between the L-shaped connecting rod 26 and the limiting inner groove 32.

[0029] When the old circular brush 2 is no longer usable, use an auxiliary tool to remove the positioning screw assembly 27. Then, the L-shaped connecting rod 26 loses its restraint. Rotate the connecting post 21 clockwise to remove the L-shaped connecting rod 26 from the limiting inner groove 32, and separate the connecting post 21 from the inner connecting ring 3. The old circular brush 2 can then be discarded and replaced with a new one. When the circular brush 2 is no longer washable and needs to be completely replaced, the connecting post 21 can be removed separately, and only the circular brush 2 and the inner connecting ring 3 can be replaced, which can reduce the cost of replacing parts.

[0030] In other embodiments, this embodiment discloses, please refer to Figure 1 , Figure 4 As shown, the L-shaped connecting rod 26 is arranged in a ring around the outside of the connecting post 21. The number of semi-open connecting grooves 31, limiting inner grooves 32, and positioning screw assemblies 27 is the same as that of the L-shaped connecting rod 26. This design increases the contact points between the connecting post 21 and the inner connecting ring 3, thereby improving the tightness of the connection between the two.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
