[0002] A household floor scrubber primarily consists of a main unit and a floor brush. The main unit is equipped with a water tank (to supply water to the drum) and a wastewater tank (to collect wastewater). It also features a controller, a spray device, a drum motor for controlling the drum, a suction device, and a main motor for controlling the suction device. The floor brush primarily houses the drum and a drainage channel for cleaning the floor.

[0003] Floor scrubbers use a crawler-type mop to clean the floor. For example, Chinese patent CN202220607707.9 discloses a highly efficient floor scrubber that includes a main unit and a floor brush movably connected to the bottom of the main unit. The floor brush includes a housing with a connector for connecting to the main unit and a roller brush chamber at the front end for mounting a roller brush. The roller brush assembly utilizes a crawler-type roller brush.

All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] See also Figure 1-5 The present invention provides a technical solution: a quick-detachable floor brush structure for a floor scrubber, comprising: a floor brush body 1, an active roller 2, an active wheel fixing frame 3, a driven roller 4, a driven wheel fixing frame 5 and a crawler rag 6. The active roller 2 is rotatably mounted on the floor brush body 1, a support rod 11 is provided on the floor brush body 1, the active wheel fixing frame 3 is detachably mounted on the support rod 11, one end of the active roller 2 contacts the active wheel fixing frame 3, a first magnet 31 is provided on the active wheel fixing frame 3, and the driven roller 4 is rotatably mounted on the floor brush body 1. One end of the wheel 4 is plugged into the connecting head 7, and the connecting head 7 is rotatably mounted on the floor brush body 1. A second magnet 71 is provided on the connecting head 7, and a third magnet corresponding to the second magnet 71 is provided on the end face of the driven roller 4. A driven wheel fixing frame 5 is provided at one end of the driven roller 4, and the driven roller 4 is rotatably mounted on the driven wheel fixing frame 5. A fourth magnet 51 corresponding to the first magnet 31 is provided on the driven wheel fixing frame 5, and a crawler rag 6 surrounds the active roller 2 and the driven roller 4.

[0032] A through hole 32 is provided on the driving wheel fixing frame 3, and the driving roller 2 is passed through the through hole 32. A plurality of rollers 321 arranged along the circumference of the through hole 32 are provided on the inner wall of the through hole 32. The surface of the roller 321 contacts the side wall of the driving roller 2. There are four rollers 321. The driving wheel fixing frame 3 positions the driving roller 2. The driving wheel fixing frame 3 contacts the driving roller 2 through four small rollers 321 to avoid friction with the driving roller 2, thereby ensuring smooth rotation of the driving roller 2.

[0033] The driving wheel fixing frame 3 is provided with a mounting groove 33 for mounting the first magnet 31. A countersunk hole 331 is provided on the bottom surface of the mounting groove 33. A fastener is provided in the countersunk hole 331. The driving wheel fixing frame 3 is fixedly mounted on the support rod 11 by the fastener, thereby realizing the detachable installation of the driving wheel fixing frame 3 and hiding the mounting structure of the driving wheel fixing frame 3 to prevent the driving wheel fixing frame 3 from being loosened during installation.

[0034] At least one plug-in plate is provided on the back of the driving wheel holder 3, and a slot 111 is provided on the end face of the support rod 11, which corresponds to the position of the plug-in plate. The driving wheel holder 3 is fixed to the support rod 11 through the cooperation of the plug-in plate and the slot 111. On the one hand, this facilitates the installation of fasteners and the assembly and disassembly of the driving wheel holder 3; on the other hand, it improves the connection between the driving wheel holder 3 and the support rod 11, preventing the driving wheel holder 3 from loosening during installation, ensuring that the first magnet 31 of the driving wheel holder 3 can align with the fourth magnet 51 of the driven roller 4, and thus ensuring the installation of the driven roller 4.

[0035] A plurality of notches 332 arranged circumferentially are provided on the sidewall of the mounting slot 33 to facilitate taking in and placing the first magnet 31 of the mounting slot 33 .

[0036] A synchronous belt 61 is provided on the inner wall of the crawler rag 6, and a plurality of first grooves 21 are provided on the active roller 2 along the outer circumference, and the first grooves 21 are used to engage with the synchronous belt 61. A plurality of second grooves 41 are provided on the driven roller 4 along the outer circumference, and the second grooves 41 are used to engage with the synchronous belt 61, so that the active roller 2 can drive the driven roller 4 to rotate through the crawler rag 6.

[0037] Working Principle: The active roller 2 on the floor brush body 1 is driven by a drive device to rotate. The active roller 2 drives the driven roller 4 to rotate via the crawler mop 6. To remove the crawler mop 6, pull the driven roller 4 from the side of the floor brush body 1, then remove the crawler mop 6. To install the crawler mop 6, first place the crawler mop 6 over the active roller 2, then insert the driven roller 4. The position of the driven roller 4 is secured by the driven roller mounting bracket 5 and the connector 7. One end of the driven roller 4 is fixed to the second magnet 71 of the connector 7 via a third magnet, and the other end is fixed to the first magnet 31 of the active roller mounting bracket 3 via a fourth magnet 51, preventing the driven roller 4 from falling off. The crawler mop 6 is tensioned by the active roller 2 and the driven roller 4. The driven roller 4 is fixed by magnets, allowing for quick disassembly and assembly, thus facilitating the removal and installation of the crawler mop and facilitating cleaning of the mop.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
