[0023] Reference Figures 1 to 6 A roller brush installation structure of a floor cleaning machine includes a floor brush, and the floor brush includes a floor brush housing 1 and a roller brush 2. A roller brush cavity 11 for accommodating the roller brush is provided at the front side of the floor brush housing 1, and the roller brush 2 can be exposed through the opening of the roller brush cavity 11 to roll and wipe the floor.

[0024] The roller brush 2 is installed into the roller brush cavity 11 for cleaning or removed from the roller brush cavity 11 for disassembly and replacement by rotating the bracket 3 .

[0025] The rotating bracket 3 includes a rotating arm 31 and a sleeve portion 32, one end of the rotating arm 31 is hinged to the outer wall of one side of the floor brush housing 1, the sleeve portion 32 is arranged at the other end of the rotating arm 31 and the axis of the sleeve portion 32 intersects with the axis of the rotating arm, the roller brush 2 is detachably sleeved on the sleeve portion 32, and the sleeve portion 32 of the sleeved roller brush 2 is moved out of the roller brush cavity 11 by the rotating arm 31, so that the replacement operation of the roller brush 2 is located outside the floor brush housing 1 as a whole, which is conducive to the disassembly and replacement of the roller brush 2, and after the roller brush 2 is completely removed by the rotating bracket 3, it is also very convenient to clean the dust suction port, and due to the setting of the rotating bracket 3, the installation and disassembly of the roller brush 2 have clear directionality, and the roller brush 2 is moved out of or into the roller brush cavity 11 by the rotating bracket 3, which is conducive to the rapid disassembly and assembly of the roller brush 2.

[0026] A hinge structure is provided on the outer wall of one side of the floor brush housing 1, and the rotating arm 31 is hinged on the hinge structure. The rotating arm 31 can rotate in different directions to realize the roller brush 2 to move out of the roller brush chamber 11, such as swinging up and down, or swinging left and right; and the utility model preferably has the rotating arm 31 swinging left and right to make the roller brush 2 move out of or into the roller brush chamber 11 from the front and back direction; specifically, the hinge structure includes a sink groove Ⅰ12 located on the outer wall of the floor brush housing 1 and a hinge shaft 5 installed and penetrated on the upper and lower side walls of the sink groove Ⅰ12, and the end of the rotating arm 31 is hinged by the hinge shaft 5 and can rotate horizontally in the left and right directions; and after the rotating arm 31 transfers the roller brush 2 into the roller brush chamber 11, the rotating arm 31 is accommodated in the sink groove Ⅰ12, and the rotating arm 31 is limited up and down by the sink groove Ⅰ12, and the limit of the rotating arm 31 can limit the jumping of the roller brush 2 during rolling cleaning. As a preferred solution, a driving motor 4 for driving the roller brush to rotate is installed in the sleeve portion 32, and the driving motor 4 has a driving head 41. The roller brush 2 is provided with a transmission seat 26 that is transmission-connected to the driving head 41. There is no need to arrange the motor and the transmission structure in the floor brush housing 1. This design of directly sleeve the motor can effectively simplify the structure of the floor brush and reduce costs. Moreover, since the rotating bracket 3 is installed through the above-mentioned hinge structure, in this embodiment, the hinge shaft 5 is a screw that penetrates into the sink groove Ⅰ12 from the bottom and is fixed by a top nut. The rotating bracket 3 can be removed together with the driving motor 4 by removing the hinge shaft 5, which is convenient for inspection and replacement.

[0027] The roller brush 2 includes a cleaning roller 21 and an end cover 22 for sealing one of the ports of the cleaning roller 21. A locking device is provided on the end cover 22. The cleaning roller 21 is sleeved on the sleeve portion 32 through another port, and a sealing ring 6 is arranged on the sleeve portion 32 to seal the port. A buckling structure cooperating with the locking device is provided on the other side of the floor brush housing 1. When the locking device and the buckling structure are relatively locked and fixed, the rotating bracket 3 cannot rotate outward, so that the roller brush 2 can be stably installed in the roller brush cavity 11. Specifically, the end cover 22 includes a plug 221 and a rotating end cover 222 rotatably connected to the plug 221. The locking device is fixed on the rotating end cover 222. The plug 221 is clamped in the port of the cleaning roller 21. When the locking device and the buckling structure are relatively locked, the plug 221 can rotate relative to the rotating end cover 222 without hindering the rotation of the roller brush 2. The locking device includes an articulated lock 23, on which is provided an elastically retractable plug-in buckle 24 and a trigger 25 that can push the plug-in buckle 24 to retract. The snap-fit ​​structure is provided with an insertion hole 13 corresponding to the plug-in buckle 24. After the insertion port on the articulated lock 23 is inserted into the insertion hole 13, the locking device and the snap-fit ​​structure are locked. After the trigger 25 is pushed in the extension direction opposite to the plug-in buckle 24, the plug-in buckle 24 is disengaged from the insertion hole 13 to unlock the locking device and the snap-fit ​​structure. Preferably, the buckling structure also includes a groove II 14, and the insertion hole 13 is arranged on the side wall of the groove II 14. After the insertion buckle 24 is inserted into the insertion hole 13, the hinged lock buckle 23 is installed in the groove II 14, and the hinged lock buckle 23 is limited up and down by the groove II 14. By limiting the hinged lock buckle 23 and coordinating the limiting between the rotating arm 31 on the other side and the groove I 12, the jumping of the roller brush 2 during rolling cleaning can be further limited, thereby achieving a smooth and uniform cleaning effect of the roller brush 2 on the ground.

[0028] In order to enable the sleeve portion 32 to turn a corner and enter the roller brush cavity 11, the axis of the sleeve portion 32 is arranged to intersect with the axis of the rotating arm 31, and preferably, since most floor brushes are regular square structures, the axis of the sleeve portion 32 is perpendicular to the axis of the rotating arm 31 and is arranged at right angles. When the roller brush 2 is installed in the roller brush cavity 11, it can be easily positioned with the help of the wall surface of the floor brush shell 1 so that the roller brush 2 can be facing perpendicular to the forward direction of the floor brush.

[0029] As a preferred solution, a magnetic component 15 is provided on the floor brush housing 1, and a suction component 33 engaged with the magnetic component 15 is correspondingly provided on the rotating arm 31. In this embodiment, the magnetic component 15 is preferably a magnet, and the suction component 33 is preferably a metal sheet. The rotating arm 31 swings to make the suction component 33 engage with the magnetic component 15, so that the rotating bracket 3 is suction-connected with the floor brush housing 1, so that the rotating bracket 3 is installed more firmly, and the suction of the suction component 33 and the magnetic component 15 can indicate that the roller brush 2 is transferred into the roller brush cavity 11 and installed in place.
