[0031] First embodiment

[0032] When the floor scrubber is cleaning the floor, it is in a moving state. The brush head is driven by the brush disc motor to rotate to clean the floor. Then, the rubber scraper 3 on the squeegee 1 scrapes the dirty water off the floor and sucks it into the dirty water tank to take it away from the site. Since the rubber scraper will wear out after long-term use, which will affect its effect of scraping dirty water, it needs to be disassembled and replaced. However, the rubber scraper 3 currently used will age and harden due to long-term use, making the disassembly process more cumbersome. In order to avoid the cumbersome and inconvenient disassembly of the aged and hardened rubber scraper, refer to Figure 1 - Figure 3 and Figure 7 The present embodiment provides a quick-release structure of a rubber scraper for a floor scrubber, which is composed of a squeegee 1, two arc-shaped baffles 2, two rubber scraper strips 3 and a clamping mechanism 4. The two arc-shaped baffles 2 are integrally formed on both sides of the bottom of the squeegee 1, and the two rubber scraper strips 3 are respectively located on both sides of the squeegee 1, and the two rubber scraper strips 3 slide between the two sides of the squeegee 1 and the two arc-shaped baffles 2.

[0033] In order to facilitate the staff to quickly disassemble the rubber scraper for replacement and reduce the trouble in the process of disassembling the rubber scraper, a clamping mechanism 4 is arranged at one end of the squeegee 1 for fully inserting the rubber scraper strip 3 between the squeegee 1 and the arc-shaped baffle 2 and fixing it.

Arc grooves 43 are respectively provided on both sides of the squeegee 1, and limiting clips 44 fixed to the two rubber scraper strips 3 are respectively slidably arranged on the inner sides of the two arc grooves 43. When the rubber scraper strip 3 is installed, the rubber scraper strip 3 drives the limiting clip 44 to slide on the inner side of the arc groove 43. When the rubber scraper strip 3 is installed, the middle part of the limiting clip 44 is located in the limiting groove 41.

[0034] Second embodiment

[0035] In order to fix and clamp the two rubber scrapers 3 on the squeegee 1 at the same time, and to disassemble them simultaneously, so that the process of disassembling and assembling the rubber scrapers 3 is more convenient, and at the same time, the stability of the rubber scrapers fixed on the squeegee 1 is improved, Figure 4 - Figure 5 In this embodiment, a clamping assembly 45 for clamping and fixing the limiting clamping strip 44 on the squeegee 1 is provided at the top of the sliding block 42.
