[0026] To further clarify the technical means and effects taken by the present application to achieve the predetermined purposes, the specific embodiments, structures, features and effects thereof according to the present application are described in detail below in combination with the drawings and preferred embodiments. In the following description, different "an embodiment" or "embodiments" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0027] As shown in Figures 1-5 , the brush mechanism includes a base 1 with built-in driving device, a roller brush assembly 2, and a brush cover, which generally includes a brush inner cover 32 and a brush outer cover 31. The brush inner cover 32 is mainly used to shield the roller brush assembly 2, and the brush outer cover 31 is detachably connected to the base 1. The base 1 has a roller brush groove 11 for assembling the roller brush assembly 2. One end of the roller brush assembly 2 is detachably connected to the driving device, and the other end is rotatably assembled in the roller brush groove 11 through a roller brush assembly and disassembly structure.

[0028] The brush cover is shielded above the roller brush assembly 2 to avoid sweeping garbage or sewage upwards when the roller brush 2 is working. When cleaning the ground with the brush mechanism, the roller brush assembly 2 is in abutment with the ground, and the roller brush assembly 2 rotates around its connecting shaft, thereby achieving cleaning by dragging and washing the ground through the rotation of the roller brush assembly 2.

[0029] ​The first end side of the rolling brush groove 11 is provided with a first coupling shaft 12 connected with the driving device, and the first end of the rolling brush assembly 2 is provided with a second coupling shaft 21 coupled with the first coupling shaft 12. The second coupling shaft 21 of the rolling brush assembly 2 is coupled with the first coupling shaft 12 of the rolling brush groove 11, so that the first end of the rolling brush assembly 2 is rotatably assembled to the first end side of the rolling brush groove 11.

[0030] The second end of the rolling brush assembly 2 is rotatably assembled to the second end side of the rolling brush groove 11 through a rolling brush dismounting structure. The rolling brush dismounting structure makes the rolling brush assembly 2 have the characteristics of convenient installation and dismounting operation relative to the rolling brush groove 11 of the base 1, which is convenient for users to use.

[0031] The rolling brush dismounting structure specifically comprises: an assembly groove 13 opened in the second end side of the rolling brush groove 11, the groove opening of the assembly groove 13 extends upward; a rolling brush handle 4 limit assembled with the assembly groove 13, the rolling brush handle 4 comprises an assembly part 41 limit connected with the assembly groove 13 and a handle part 42 located at the upper end of the assembly part 41, the assembly part 41 has a shaft sleeve 410; the second end of the rolling brush assembly 2 is inserted into the shaft sleeve 410, and the assembly part 41 is inserted downward from the groove opening and limit matched with the assembly groove 13, so as to realize the rotatable assembly of the second end of the rolling brush assembly 2 to the second end side of the rolling brush groove 11.

[0032] The second end of the rolling brush assembly 2 is provided with a bearing 22, which is inserted into the shaft sleeve 410 of the rolling brush handle 4, so that the second end of the rolling brush assembly 2 is rotatably connected with the rolling brush handle 4. Therefore, after the rolling brush handle 4 is inserted downward from the groove opening of the assembly groove 13, the assembly part 41 is limit matched with the assembly groove 13, so as to realize the quick assembly of the rolling brush assembly 2 to the rolling brush groove 11 of the base 1.

[0033] The rolling brush assembly 2 generally comprises a rotating shaft and a rolling cylinder sleeved on the rotating shaft, therefore, the second coupling shaft 21 and the bearing 22 are respectively fixed at the first end and the second end of the rotating shaft.

[0034] An shaft hole 411 coaxial with the rotating shaft of the rolling brush assembly 2 is arranged on the assembly part 41, the second end of the rotating shaft passes through the shaft hole 411, and the bearing 22 rotates relative to the shaft sleeve 410 of the assembly part 41.

[0035] Further combined Figures 6-9 An arc-shaped recess 412 is arranged on the outer side of the assembly part 41 away from the rolling brush assembly 2, for example, the arc-shaped recess 412 is opened on the outer circumferential side of the shaft hole 411; the assembly groove 13 is correspondingly provided with an arc-shaped protrusion 131, after the rolling brush handle 4 is inserted downward from the groove opening of the assembly groove 13, the assembly part 41 is limit matched with the arc-shaped protrusion 131 through the arc-shaped recess 412, so that the rolling brush handle 4 is limit assembled in the assembly groove 13.

[0036] The lower end of the assembly part 41 is provided with a circular arc buckle 413, and the bottom of the assembly groove 13 is correspondingly provided with a circular arc support platform 133. When the assembly part 41 is inserted into the assembly groove 13, the circular arc support platform 133 provides downward insertion guidance for the circular arc buckle 413, and when the circular arc buckle 413 is downwardly sleeved on the circular arc support platform 133, the roller brush handle 4 is downwardly inserted into the assembly groove 13 and is assembled in place. At this time, the arc-shaped convex part 131 of the assembly groove 13 is just clamped into the arc-shaped concave part 412 of the assembly part 41 to form a limiting fit, so that the roller brush handle 4 is limited and assembled in the assembly groove 13.

[0037] In addition to the limiting fit formed by the arc-shaped concave part 412 and the arc-shaped convex part 131 between the roller brush handle 4 and the assembly groove 13, two elastic support feet 414 are respectively formed at the lower end of the assembly part 41 on the two opposite sides of the circular arc buckle 413. At least one side surface of the elastic support foot 414 is provided with a first limiting part, and the assembly groove 13 is correspondingly provided with a second limiting part. The first limiting part and the second limiting part form a limiting fit.

[0038] For example, the inner side surface of the elastic support foot 414 is provided with a first outward convex limiting part 416, and the two sides of the circular arc support platform 133 are correspondingly provided with a first inward concave limiting part 135. The first outward convex limiting part 416 and the first inward concave limiting part 135 form a limiting fit. Or / and, the outer side surface of the elastic support foot 414 is provided with a second inward concave limiting part 415, and the two side walls of the assembly groove 13 are correspondingly provided with a second outward convex limiting part 134. The second outward convex limiting part 134 and the second inward concave limiting part 415 form a limiting fit.

[0039] In addition, a limiting shoulder part 421 is formed at the connection between the handle part 42 and the assembly part 41, and a stop block 132 is correspondingly provided on the two side walls of the assembly groove 13. When the roller brush handle 4 is inserted into the assembly groove 13 and is assembled in place, the bottom end of the limiting shoulder part 421 abuts against the top end of the stop block 132, so that the assembly positioning of the roller brush handle 4 inserted into the assembly groove 13 is realized by the cooperation of the stop block 132 and the limiting shoulder part 421.

[0040] Especially see Figure 10In order to avoid the limit assembly structure between the rolling brush handle 4 and the assembly slot 13 from being damaged by the vibration of the rolling brush assembly 2 during rotation, the abutting portion 321 is arranged at one end of the mop inner cover 32. After the mop inner cover 32 is assembled to the base 1, the abutting portion 321 is pressed on the handle portion 42 of the rolling brush handle 4. The mop outer cover 31 is detachably connected to the base 1 to assemble and fix the mop inner cover 32 relative to the base 1, so that the rolling brush handle 4 is limited by the mop inner cover 32 and cannot be pulled out of the assembly slot 13. Therefore, the rolling brush assembly 2 is stably and reliably assembled in the rolling brush slot 11 by the rolling brush handle 4. Meanwhile, the noise caused by the up-and-down movement of the rolling brush assembly 2 due to the displacement of the rolling brush handle 4 relative to the rolling brush slot 11 during high-speed rotation is reduced, and the up-and-down movement of the rolling brush assembly 2 is avoided to ensure that the rolling brush assembly 2 abuts against the ground, thereby having reliable cleaning capacity.

[0041] The operation of installing the rolling brush assembly 2 into the rolling brush slot 11 of the base 1 is as follows: first, the second coupling shaft 21 at the first end of the rolling brush assembly 2 is coupled and connected to the first coupling shaft 12 of the rolling brush slot 11; then, the second end of the rolling brush assembly 2 is inserted into the shaft sleeve 410 of the rolling brush handle 4; finally, the handle portion 42 of the rolling brush handle 4 is inserted downward from the slot opening of the assembly slot 13. The circular arc support table 133 provides downward insertion guidance to the circular arc buckle 413. When the bottom end of the limit shoulder 421 abuts against the top end of the stop block 132, the insertion is assembled in place. At this time, the back side of the assembly portion 41 forms a limit fit with the arc-shaped convex portion 131 of the assembly slot 13 by using the arc-shaped recessed portion 412. Meanwhile, the first limit portion of the elastic support foot 414 at the lower end of the assembly portion 41 also forms a limit fit with the second limit portion of the assembly slot 13. Finally, the mop cover is arranged on the base 1, and the abutting portion 321 of the mop cover is pressed on the handle portion 42 of the rolling brush handle 4, thereby completing the assembly of the rolling brush assembly 2.

[0042] When the rolling brush assembly 2 needs to be disassembled for cleaning, the reverse operation of assembling the rolling brush assembly 2 is performed, which will not be repeated here.

[0043] In addition, the first coupling shaft 12 and the second coupling shaft 21 preferably adopt a helical spline structure. When the rolling brush assembly 2 needs to be disassembled, the second end of the rolling brush assembly 2 is pulled up by the rolling brush handle 4. The helical spline structure between the first coupling shaft 12 and the second coupling shaft 21 has a small resistance, which facilitates the disconnection of the second coupling shaft 21 of the rolling brush handle 4 relative to the first coupling shaft 12, thereby further facilitating the disassembly of the rolling brush assembly 2 from the rolling brush slot 11 of the base 1.

[0044] This utility model also discloses a cleaning device that implements the aforementioned floor brush mechanism. The actual cleaning device is a vacuum cleaner, floor scrubber, or similar product, featuring a roller brush assembly 2 that is easily detached from the base 1 for convenient use.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
