In this embodiment, the sleeve 22 is a long cylinder structure, and a rolling brush groove is formed at one end of the sleeve 22, and the rolling brush groove is connected with the shaft sleeve teeth 1511 of the driving shaft sleeve 151 in a matching manner, so that the rolling brush driving mechanism 10 can drive the sleeve 22 to rotate synchronously when working, and the rolling brush 21 rotating synchronously with the sleeve 22 is used for cleaning. To facilitate removal of the roller brush mechanism 20.

It should be understood that the scrubber may also include other components, which are not fully listed here.

When the floor cleaning machine needs to perform cleaning work, the driving motor 11 in the roller brush driving mechanism 10 of the floor cleaning machine works, the driving motor shaft 110 rotates, the motor shaft 110 drives the motor input gear 121 sleeved with the motor shaft to rotate, the motor input gear 121 drives the reduction gear unit 122 meshed with the motor input gear to rotate, the reduction gear unit 122 drives the first belt pulley 131 connected with the reduction gear unit to rotate, the first belt pulley 131 drives the second belt pulley 132 to rotate through the conveyor belt 133, the wheel shaft 1321 of the second belt pulley 132 drives the shaft sleeve component 15 connected with the second belt pulley to rotate, the shaft sleeve component 15 drives the sleeve 22 of the roller brush mechanism 20 to rotate, and cleaning is performed through the roller brush 21 synchronously rotating with the sleeve 22.

The rolling brush gear driving mechanism of the floor washing machine provided by the embodiment has the beneficial effects that: through the structural design of the round brush in this implementation, the user can take the floor cleaning machine through the realization that presses the button 407 and draws the pull ring 406 to can carry out quick replacement to the brush head of floor cleaning machine and the round brush in the brush head.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
