[0028] Through the design of the scraper assembly 5, the pushing mechanism 6, the cleaning disc 2 and the splicing disc 3, during the process of cleaning the ground, the staff can start the pushing mechanism 6 to push the connecting plate 401 to drive the splicing disc 3 to move vertically downward, thereby driving the bristles of the cleaning disc 2 on the lower surface of the splicing disc 3 to touch the ground, and at the same time, it will also drive the scraper assembly 5 detached and installed on the lower surface of the cleaning disc 2 to touch the ground together and can rotate with the cleaning disc 2 to clean and scrape the debris on the ground, and through the design of the scraper assembly 5, the sticky debris on the ground can be scraped off, thereby ensuring the cleanliness of the ground, making the cleaning process cleaner;

[0029] The scraper assembly 5 will be pushed down by the pushing mechanism 6 to make it touch the ground with greater force, so that the sticky materials on the ground can be scraped off.

[0030] like Figure 3-Figure 7 As shown, the pushing mechanism 6 includes a second motor 601, which is fixedly installed in the floor scrubber frame 1. A threaded rod 602 is fixedly installed at one end of the output shaft of the second motor 601. A movable block 603 is threadedly installed on the outer surface of the threaded rod 602. The movable block 603 is fixedly installed at one end of the connecting plate 401.

[0031] The movable block 603 is guided to slide in the floor scrubber frame 1, so that the movable block 603 is restricted from sliding.

[0032] The scraper assembly 5 includes a mounting tube 502, which is fixedly installed in the embedded groove 201, and the embedded groove 201 is opened on the lower surface of the splicing plate 3. A connecting column 504 is rotatably installed in the mounting tube 502, and a scraper plate 505 is fixedly installed on the outer surface of the connecting column 504. The scraper plate 505 is inclined and touches the ground together with the bristles of the cleaning plate 2.

[0033] A fastening disk 501 is fixedly installed between the three groups of installation tubes 502 , and is disassembled and installed on the lower surface of the splicing disk 3 through the fastening disk 501 , while the installation tubes 502 are fitted into the embedded grooves 201 .

[0034] Rotating columns 506 are fixedly installed at both ends of the connecting column 504 , a torsion spring 503 is fixedly installed on the outer surface of the rotating column 506 , and the other end of the torsion spring 503 is fixedly installed in the installation tube 502 .

[0035] Through the design of the second motor 601, the threaded rod 602, the moving block 603, the mounting tube 502, the scraper plate 505, the torsion spring 503 and the connecting column 504, when cleaning the floor, the second motor 601 can be started to drive the threaded rod 602 to drive the moving block 603 to move vertically, so that the moving block 603 can drive the bristles of the cleaning disc 2 on the lower surface of the splicing disc 3 to touch the floor, and at the same time, it will also drive the scraper plate 505 disassembled and installed on the lower surface of the cleaning disc 2 to touch the floor and can rotate with the cleaning disc 2 to clean and scrape the debris on the floor, and in the process of the second motor 601 pushing the cleaning disc 2 downward through the threaded rod 602, the scraper plate 505 on the lower surface of the cleaning disc 2 will be affected by the ground.

Increasing the inclination of the scraper plate 505 can more accurately correct the unevenness of the surface, thereby improving the contact rigidity and reducing wear.

[0036] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when cleaning the ground, the second motor 601 can be started to drive the threaded rod 602 to drive the movable block 603 to move vertically, so that the movable block 603 can drive the bristles of the cleaning disc 2 on the lower surface of the splicing disc 3 to touch the ground, and at the same time, it will also drive the scraper plate 505 disassembled and installed on the lower surface of the cleaning disc 2 to touch the ground and can rotate with the cleaning disc 2 to clean and scrape the debris on the ground. In the process of the second motor 601 pushing the cleaning disc 2 downward through the threaded rod 602, the scraper plate 505 on the lower surface of the cleaning disc 2 will be pressed by the ground. The scraper plate 505 can then be rotated in the mounting tube 502 via the connecting column 504. During the rotation of the connecting column 504 in the mounting tube 502, the connecting column 504 will twist the torsion spring 503 in the mounting tube 502 together through the rotating column 506 on one side. The torsion spring 503 will apply a reverse torsion force to the scraper plate 505 through the torsion force, so that the scraper plate 505 can touch the ground through the torsion force. Then the first motor 403 can be started to drive the bristles of the cleaning disc 2 to clean the ground, and at the same time, the scraper plate 505 will be driven to rotate together, and the scraper plate 505 can scrape away the sticky materials that the bristles cannot clean.
