[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but is merely representative of selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figures 1-7 , the present invention provides a technical solution: a track-type roller brush for a floor washer, comprising:

[0040] A driving roller assembly 1, which includes a first roller bracket 11 and a driving roller 12. The driving roller 12 is rotatably installed on the first roller bracket 11, and a plurality of first grooves 121 are provided on the surface of the driving roller 12 and surround the outer circumference;

[0041] A driven roller assembly 2, which includes a second roller bracket 21 and a driven roller 22. Symmetrically arranged second roller brackets 21 are provided at both ends of the driven roller 22. The second roller bracket 21 is elastically connected to the first roller bracket 11 through a first elastic member 211. The track-type rag 4 is a flexible ring structure. The track-type rag 4 surrounds the driving roller 12 and the driven roller 22. A plurality of protrusions 41 are provided on the track-type rag 4 and surround the inner circumference. The protrusions 41 are engaged with the first grooves 121. A second groove 221 for avoiding the protrusions 41 is provided on the driven roller 22. The second groove 221 is an annular groove surrounding the outer circumference of the driven roller 22;

[0042] A rag release assembly 3, which includes a push rod 31 and a release button 32. The push rod 31 is elastically connected to the first roller bracket 11 through a second elastic element 33. The push rod 31 is arranged along the length direction of the first roller bracket 11. A pushing block 311 is provided on the push rod 31. A guiding block 212 corresponding to the pushing block 311 in position is provided on the second roller bracket 21. A first inclined surface for contacting the pushing block 311 is provided on the guiding block 212. A cavity is provided at one end of the push rod 31. A mounting plate 312 is provided in the cavity. Symmetrically arranged release buttons 32 are provided on both sides of the mounting plate 312. A sliding groove 321 corresponding to the mounting plate 312 in position is provided on the release button 32. A first connecting column 322 is further provided on the back of the release button 32. The end of a third elastic element 34 is sleeved on the first connecting column 322. A second inclined surface 323 is provided on the release button 32.

[0043] The first roller bracket 11 includes a fixed frame 111, an upper cover plate 112, and a lower cover plate 113. Symmetrically arranged fixed frames 111 are provided at both ends of the driving roller 12. The upper cover plate 112 is fixedly installed on the fixed frame 111. The lower cover plate 113 is fixedly installed on the fixed frame 111. A connecting plate 1131 is provided on the lower cover plate 113. The connecting plate 1131 extends into the push rod 31. One end of the second elastic element 33 abuts against the connecting plate 1131, and the opposite end abuts against the push rod 31, realizing that the push rod 31 is elastically connected to the first roller bracket 11 through the second elastic element 33.

[0044] A first roller 1121 is provided on the surface of the upper cover plate 112. The first roller 1121 contacts the inner wall of the track-type rag 4. A second roller is provided on the surface of the lower cover plate 113. The upper cover plate 112 and the lower cover plate 113 are located on the upper and lower sides of the first roller bracket 11, and the track-type rag 4 is tightened by the first roller 1121 and the second roller, increasing the tension of the track-type rag 4 and ensuring the flatness of its ground contact surface.

[0045] A driving device 13 for driving the driving roller 12 is provided inside the first roller bracket 11. The driving device 13 serves as a power source and includes a driving motor and a gearbox. The driving device 13 drives the driving roller 12. The driving roller 12 drives the track-type rag 4 to rotate through gear engagement. The track-type rag 4 drives the driven roller 22 to rotate through friction, forming a closed-loop track movement.

[0046] The surface of the driving roller 12 is coated with a rubberized layer, specifically, rubberized leather is provided on the surface of the driving roller 12 to increase the friction with the track-type rag 4.

[0047] A hook 213 is provided on the second roller bracket 21, and a stop block corresponding to the hook 213 in position is provided on the inner wall of the first roller bracket 11. When the driven roller 22 returns to its position and tightens the crawler-type cleaning cloth 4, the hook 213 hooks the stop block to limit the stroke of the second roller bracket 21.

[0048] The first elastic member 211 is a tension spring to realize the automatic contraction and return of the driven roller 22. When the push rod 31 pops out, the first elastic member 211 drives the driven roller 22 to contract towards the driving roller 12, and squeezes the push block 311 through the first inclined surface on the guide block 212, which is convenient for ensuring the popping out of the push rod 31.

[0049] Working principle: When the crawler-type roller brush is in a normal working state, the third elastic element 34 is in an uncompressed state. At this time, the top of the release button 32 extends out of the cavity at the end of the push rod 31 and abuts against the inner wall of the first roller bracket 11, preventing the push rod 31 from moving in the axial direction under the action of the second elastic element 33.

[0050] When it is necessary to disassemble the crawler-type cleaning cloth 4, toggle the two release buttons 32 to move them towards each other. At this time, the top of the release button 32 retracts into the cavity at the end of the push rod 31, unlocking the push rod 31. Therefore, the push rod 31 pops out under the action of the second elastic element 33 (that is, the end of the push rod 31 extends out of the first roller bracket 11). At the same time, the push block 311 no longer squeezes the first inclined surface on the guide block 212. Therefore, under the action of the first elastic member 211, the second roller bracket 21 drives the driven roller 22 to contract towards the driving roller 12, so that the crawler-type cleaning cloth 4 is no longer in a tensioned state, which is convenient for removing the crawler-type cleaning cloth 4.

[0051] When installing the crawler-type cleaning cloth 4, after putting the crawler-type cleaning cloth 4 on the driving roller 12 and the driven roller 22, rotate and adjust the position so that the protruding part 41 on the inner wall of the crawler-type cleaning cloth 4 meshes with the first groove 121 on the surface of the driving roller 12 to achieve tooth engagement. Then, press the end of the push rod 31 so that the push rod 31 retracts into the first roller bracket 11. During the pressing process, the second inclined surface 323 at the top of the release button 32 contacts the first roller bracket 11, and the release button 32 moves downward, compressing the third elastic element 34. Until the push rod 31 retracts in place, the third elastic element 34 is released again, so that the top of the release button 32 extends out of the cavity at the end of the push rod 31 and abuts against the inner wall of the first roller bracket 11. During the retraction of the push rod 31, the push block 311 squeezes the first inclined surface on the guide block 212, so that the second roller bracket 21 drives the driven roller 22 to move away from the driving roller 12, and the first elastic member 211 is stretched. After the push rod 31 retracts in place, the driven roller 22 returns to its position and tightens the crawler-type cleaning cloth 4.

[0052] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
