Detailed Implementation

[0026] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0027] The accompanying drawings of this application illustrate an embodiment using a vacuum cleaner as a cleaning device. Of course, the cleaning device described in this application can also be other cleaning equipment products such as a floor scrubber.

[0028] like Figure 1-8 As shown, this application discloses an edge-cleaning floor brush, including a base, a roller brush 3, and a drive assembly. The base includes a lower floor brush cover 1 and an upper floor brush cover 2 mounted on top of the lower floor brush cover 1. A first support arm 10 and a second support arm 11 are provided opposite to each other on the front side of the base. A roller brush groove is formed between the first support arm 10 and the second support arm 11. The roller brush 3 is detachably mounted in the roller brush groove of the base, and the drive assembly drives the roller brush 3 to rotate in the roller brush groove.

[0029] The base of the edge-cleaning floor brush has a collection chamber, which is connected to a fan via pipe 8. The fan creates negative pressure in the collection chamber. As the drive assembly drives the roller brush 3 to rotate within the roller brush groove, the roller brush 3 contacts the ground, carrying debris into the collection chamber. Under negative pressure, the debris enters the collection chamber and passes through pipe 8 into the rear filter for filtration, allowing airflow to expel the debris while it concentrates inside the filter.

[0030] Therefore, in order to allow the garbage on the ground to be carried into the collection cavity of the base more efficiently as the roller brush 3 rotates, soft bristles 12 are provided on the outer periphery of the roller brush groove on the bottom surface of the base. When the soft bristles 12 come into contact with the ground, they form a negative pressure zone around the roller brush 3, so that the garbage in the negative pressure zone can be carried into the collection cavity more efficiently under the action of the roller brush 3 rotating.

[0031] The drive assembly includes a drive motor 52 and a transmission wheel 54 connected to the drive motor 52 via a transmission mechanism. The transmission wheel 54 is fixed inside the first support arm 10. The two ends of the roller brush 3 are a drive end 31 and a pivot end 32, respectively. When the roller brush 3 is installed in the roller brush groove of the base, the drive end 31 of the roller brush 3 is coupled to the transmission wheel 54 so that the transmission wheel 54 can drive the roller brush 3 to rotate synchronously. The pivot end 32 of the roller brush 3 is rotatably connected to the second support arm 11 of the base.

[0032] To reduce the distance between the end of the roller brush 3 and the side of the base, the drive shaft 55, the transmission wheel 54, and the roller brush 3 are coaxially connected. The drive motor 52 is fixed to one side of the roller brush 3, and the output shaft of the drive motor 52 is parallel to the central axis of the roller brush 3. For this purpose, the transmission mechanism also includes a drive bracket 51, with the drive wheel 521 and the transmission wheel 54 respectively located at both ends of the drive bracket 51, and the drive bracket 51 is fixed inside the first support arm 10.

[0033] In some embodiments, the transmission mechanism includes a drive wheel 521 fixed to the output end of the drive motor 52 and a transmission belt 53 connecting the drive wheel 521 and the transmission wheel 54. When the drive motor 52 drives the drive wheel 521 to rotate synchronously, the transmission belt 53 drives the transmission wheel 54 to drive the roller brush 3 to rotate in the roller brush groove of the base.

[0034] Given that during the edge cleaning process, after the first arm 10 or the second arm 11 of the base is close to the wall or object, the area below the first arm 10 or the second arm 11 cannot be cleaned by the roller brush 3, this application also includes: a drive shaft 55 fixedly connected to the transmission wheel 54, and an edge cleaning assembly driven by the transmission wheel 54 through the drive shaft 55. The edge cleaning assembly works in cooperation with the roller brush 3 to clean the edge area near the wall that cannot be cleaned by the roller brush 3 when the floor brush is used for edge cleaning, thereby improving cleaning efficiency.

[0035] Specifically, the edge-following cleaning assembly includes a rotating wheel 61 that is driven by a drive shaft 55, a rotating shaft 63 that is connected to the rotating wheel 61, and a bristle brush 62 located on the base. The lower end of the rotating wheel 61 passes through the base and connects to the bristle brush 62. The bristle tufts of the bristle brush 62 extend beyond the side of the base by at least 3 mm.

[0036] In some embodiments, the drive shaft 55 is a worm gear that meshes with the rotating wheel 61. One end of the drive shaft 55 is fixedly connected to the rotating wheel 61 via a first bearing 56, and the other end of the drive shaft 55 is rotatably connected to the first support arm 10 via a first bearing 56 fixed on the first support arm 10.

[0037] A pivot hole 511 is provided in the drive bracket 51. The upper end of the rotating shaft 63 is rotatably mounted in the pivot hole 511 through a second bearing 64. The lower end of the rotating shaft 63 is coaxially and fixedly connected to the rotating wheel 61. The rotating shaft 63 provides a limit for the rotating wheel 61, making the rotating wheel 61 work more smoothly. A third bearing 65 is provided at the bottom of the base. The third bearing 65 is sleeved on the lower end of the rotating wheel 61, so that the upper and lower ends of the rotating wheel 61 are limited by the second bearing 64 and the third bearing 65 respectively, so that the rotating wheel 61 keeps its axis of rotation unchanged during rotation and ensures that the rotating wheel 61 is always engaged and connected with the drive shaft 55.

[0038] The lower end of the rotating wheel 61 passes through the base via a third bearing 65 and is connected to the brush 62. For example, the brush 62 can be locked to the lower end of the rotating wheel 61 by a screw 66. The brush 62 is provided with multiple bundles of bristles for cleaning debris along the edges. The ends of the bristles extend at least 3 mm beyond the side of the base to ensure that the brush 62 can provide efficient and reliable edge cleaning capability during rotation.

[0039] The drive shaft 55 drives the rotating wheel 61 to rotate, which in turn drives the broom 62 to rotate. During the rotation, the broom 62 uses bristles to clean below the first arm 10. The bristles of the broom 62 sweep the garbage in the area below the first arm 10 that cannot be cleaned by the roller brush 3 towards the roller brush 3, and then under the action of the roller brush 3, it is carried into the storage cavity of the base. Thus, when the cleaning device is attached to the wall or other objects for cleaning, the broom 62 can achieve efficient and reliable edge cleaning.

[0040] Furthermore, in order to facilitate users to remove the roller brush 3 for cleaning or washing during use, this application designs the roller brush 3 as a structure that is detachable from the base.

[0041] Specifically, the edge-cleaning floor brush of this application also includes a roller brush handle 7 with a bushing 71. When the roller brush 3 is installed into the roller brush groove, the drive end 31 of one end of the roller brush 3 is coupled to the transmission wheel 54, and the pivot end 32 of the other end of the roller brush 3 is inserted into the bushing 71 and is detachably connected to the second support arm 11 by the roller brush handle 7.

[0042] The lower end of the roller brush handle 7 has an elastic buckle end 73, and the second support arm 11 is provided with a corresponding fastening position 14. The elastic buckle end 73 of the roller brush handle 7 is fastened and connected with the fastening position 14 to limit the roller brush 3 to be installed in the roller brush groove.

[0043] Furthermore, a stop groove 72 is provided at the lower end of the brush handle 7, and a stop part 13 is provided on the second arm 11. When the stop groove 72 and the stop part 13 are engaged, the elastic buckle end 73 is fastened and connected to the buckle position 14.

[0044] The number of elastic buckle ends 73 is two, and the two elastic buckle ends 73 are located on both sides of the stop groove 72. The second arm 11 is provided with two fastening positions 14, which are located on both sides of the stop part 13 of the second arm 11.

[0045] Especially see Figure 5 As shown, the operation of installing the roller brush 3 into the roller brush groove of the base using the roller brush handle 7 is as follows: Align the drive end 31 of the roller brush 3 with the transmission wheel 54 inside the first support arm 10 so that the drive end 31 and the transmission wheel 54 are coupled and connected; insert the pivot end 32 of the roller brush 3 into the bushing 71 of the roller brush handle 7, and the user holds the handle part at the upper end of the roller brush handle 7 so that the roller brush handle 7 is inserted downward along the second support arm 11; when the stop groove 72 of the roller brush handle 7 and the stop part 13 of the second support arm 11 form a stop engagement, the two elastic buckle ends 73 at the lower end of the roller brush handle 7 are respectively fastened and connected to the two fastening positions 14 of the second support arm 11. The roller brush handle 7 and the second support arm 11 are limited and fixed by the fastening connection between the elastic buckle ends 73 and the fastening positions 14. Figure 8 As shown. At this time, the drive shaft 55, the transmission wheel 54, and the roller brush 3 are coaxially connected.

[0046] In addition, the base also includes a cover 4 mounted on the brush top cover 2 to enclose the roller brush groove above the roller brush 3. The cover 4 is usually made of transparent plastic, allowing users to easily observe the roller brush 3 during use and conveniently remove it for cleaning. Simultaneously, the cover 4 is also press-fitted to the upper end of the roller brush handle 7, ensuring that the roller brush handle 7 will not detach from the second support arm 11 during use, preventing the roller brush 3 from malfunctioning.

[0047] When it is necessary to remove the roller brush 3, first open the cover 4 to expose the roller brush 3 from the roller brush groove of the base. When the user holds the upper part of the roller brush handle 7 and lifts it upward, the elastic buckle end 73 of the roller brush handle 7 can be disengaged from the buckle position 14, and then the roller brush 3 can be removed from the roller brush groove. The operation is very simple.

[0048] This application also discloses a cleaning device, including the edge-cleaning floor brush as described above. The edge-cleaning component works in conjunction with the roller brush 3 to provide efficient and reliable edge cleaning. Meanwhile, the roller brush 3 can be disassembled and installed via the roller brush handle 7 and the roller brush groove relative to the base. The disassembly and installation operation is simple and convenient for users.

[0049] 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.
