[0044] The working principle of a quick-release assembly vacuum cleaner floor brush in this embodiment includes: when assembling the roller brush 2, the second positioning seat 31 is positioned on the second end 22 of the roller brush 2. First, the first end 21 is tilted and connected to the first positioning seat 11, so that the connecting shaft is connected to the interface 12. Then, with the outer end of the connecting shaft as the axis, the roller brush 2 is rotated, so that the second positioning seat 31 is assembled in the first positioning groove 13. At the same time, the multi-faceted positioning block 33 is assembled on the protruding rib 14. By pushing the toggle block 42, the locking member 4 is pressed, so that the third locking block 4 is engaged. 1. Move the third positioning seat 32 into the movable groove 16, tilt it into the first positioning groove 13, so that the first locking block 15 and the second locking block 34 are engaged. Then, rotate the third positioning seat 32 so that the wedge-shaped positioning block 351 is engaged in the second positioning groove 18. Release the locking member 4 so that it is reset under the action of elasticity. The third locking block 41 is engaged in the slot 35, realizing the structural locking of the positioning structure 3, the roller brush 2 and the floor brush body 1. When disassembling, press the locking member 4, first take out the third positioning seat 32, and then rotate the roller brush 2 to take it out.
