For those of ordinary skill in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0036] Please refer to Figures 1-5 The application provides a technical solution: a floor brush with a rolling brush cavity opening plugging mechanism, comprising:

[0037] A floor brush body 1 is provided with a rolling brush cavity 2 at the front end bottom, and a guide groove 3 is provided on the outer side of the rolling brush cavity 2 of the floor brush body 1, which extends along the width direction of the rolling brush cavity 2 to the front end front surface and the top of the floor brush body 1;

[0038] A plugging mechanism 4 is movably attached to the front end outer surface of the floor brush body 1 and plugs the opening of the rolling brush cavity 2, which comprises a plurality of plugging plates 5 connected side by side and rotating through a hinge 6, a connecting piece 7 connected to the plugging plate 5, and the connecting piece 7 is slidingly connected to the guide groove 3.

[0039] The ground brush of the present application can block the opening of the roller brush cavity when storing after cleaning, so as to avoid dust and impurities from entering the roller brush cavity and polluting the roller brush and the inner wall of the roller brush cavity, thereby ensuring the efficiency of subsequent cleaning use. When the opening of the roller brush cavity is blocked, the blocking mechanism can raise the ground brush to avoid bottom wear caused by movement, and support the ground brush and buffer external vibration. When the opening of the roller brush cavity is opened, the blocking mechanism moves to the front of the front end and the top of the ground brush, which can reinforce the front end of the ground brush and improve its impact resistance and shock resistance.

[0040] The connecting piece 7 includes a first ball shaft 8 and a connecting shaft 9. The first ball shaft 8 is positioned at the inner end of the connecting shaft 9 and is slidingly arranged in the guide groove 3 with a circular cross section. The connecting shaft 9 passes through the butt joint 10 on the outside of the guide groove 3. The outer end of the connecting shaft 9 is positioned with a second ball shaft 11 which is rotatably embedded in the spherical groove 12 of the blocking plate 5. Thus, the flexibility of the connecting piece 7 connecting with the ground brush body 1 and the blocking mechanism 4 is improved, thereby ensuring the flexibility and smoothness of the blocking mechanism 4 sliding at the corner of the surface of the ground brush body 1.

[0041] The outer surface of the blocking plate 5 is provided with a mounting groove 13, and the inner side of the buffer block 14 is embedded in the mounting groove 13, and the outer side extends to the outside of the blocking plate 5. The buffer block 14 can be selected from air bags or rubber balls, thereby further improving the impact resistance and buffering performance of the blocking mechanism.

[0042] The ground brush body 1 is provided with a first scraping strip 15 and a second scraping strip 16 on three sides outside the guide groove 3, and the side surface of the blocking mechanism 4 is combined with the first scraping strip 15 and the second scraping strip 16. The scraping strip is arranged outside the bottom roller brush cavity opening of the ground brush and is a conventional arrangement, which is generally used to block dust and impurities on the surface to be cleaned, thereby prolonging the adsorption time at the opening of the roller brush cavity, and surrounding the opening to improve the suction force and improve the dust collection and cleaning quality. When the blocking mechanism is blocked at the opening of the roller brush cavity, the scraping strip can further improve the blocking effect of the roller brush cavity, and the scraping strip can protect the blocking mechanism from lateral impact and improve the structural strength.

[0043] The end of the blocking mechanism 4 is magnetically connected with the magnets at the bottom and top of the ground brush body 1, thereby further ensuring the stability of the blocking mechanism when moving to the upper stop point (roller brush cavity opening) and the lower stop point (roller brush cavity closed) of the guide groove.

[0044] The bottom of the front end of the brush body 1 is provided with wedge-shaped flow guide surfaces 17, and the wedge-shaped flow guide surfaces 17 form flow guide notches 18 between them. The flow guide notches 18 are also commonly provided on the front side of the opening of the rolling brush cavity, which forms a narrow gap on the front side of the opening of the rolling brush cavity to improve the suction at the opening and more fully adsorb dirt on the surface to be cleaned. The front side of the sealing mechanism 4 is provided with an elastic extension piece 19, the inner side of the elastic extension piece 19 is provided with an elastic sealing block 20, and the elastic sealing block 20 closely fits the flow guide notches 18. The elastic sealing block 20 can closely fit the concave-convex structure of the rolling brush cavity, such as the flow guide notches 18, to further ensure the sealing effect of the rolling brush cavity. The flow guide notches 18, the elastic extension piece 19, and the elastic sealing block 20 are provided with mounting holes 21, and the pins or bolts pass through the mounting holes 21 of the elastic extension piece 19 and the elastic sealing block 20 and are positioned on the mounting holes 21 of the flow guide notches 18 by insertion or screwing.

[0045] The working principle of the brush with a rolling brush cavity opening sealing mechanism in the embodiment includes: when the rolling brush cavity 2 is opened, as shown in Figure 1 At this time, the sealing mechanism 4 slides to the front of the front end of the brush, the top, and the uppermost connecting piece 7 slides to the upper stop point of the guide groove 3, the sealing mechanism 4 is magnetically positioned on the brush, and when the front end of the brush collides with an object, the sealing mechanism 4 and the buffer block 14 thereon can buffer.

[0046] When the brush is used and cleaned, the sealing mechanism 4 is pushed to slide to the bottom of the brush to seal the opening of the rolling brush cavity 2. At this time, the sealing mechanism 4 closely fits the scraping strip on the side, the rear end is magnetically positioned at the bottom of the brush, the elastic sealing block 20 is embedded in the flow guide notches 18, and the pins or bolts are assembled on the mounting holes 21 to position the front end of the sealing mechanism 4, thereby stably sealing the rolling brush cavity 2, as shown in Figure 5 .

[0047] As described above, due to the adoption of the above technical scheme, the brush with a rolling brush cavity opening sealing mechanism in the embodiment has the following beneficial effects compared with the prior art:

[0048] The brush of the present application can seal the opening of the rolling brush cavity when the brush is stored after cleaning to prevent dust and other impurities from entering the rolling brush cavity and polluting the rolling brush and the inner wall of the rolling brush cavity, thereby ensuring the efficiency of subsequent cleaning and use. When the opening of the rolling brush cavity is sealed, the sealing mechanism can elevate the brush to prevent the bottom from being worn due to movement and support the brush and buffer external vibrations. When the rolling brush cavity is opened, the sealing mechanism moves to the front of the front end of the brush, which can reinforce the front end of the brush and improve its impact resistance and collision resistance.

[0049] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
