Specifically, the driving assembly 30 transmits torque through the transmission assembly 20, and the floor brush assembly 100 may further include a roller brush 50, and the roller brush 50 may be used to clean dirt, sewage, and the like remaining on a surface to be cleaned. Also, the roll brush 50 is connected to the driving assembly 20. Therefore, the driving assembly 30 can transmit the generated torque to the rolling brush 50 through the transmission assembly 20 to drive the rolling brush 50 to rotate, thereby achieving the cleaning effect of the floor brush assembly 100.

In some related art, a cleaning apparatus may include a roll brush and a drive assembly, wherein the drive assembly includes an output shaft, a motor, and a transmission case. The motor is arranged in the transmission case, a transmission shaft of the motor is connected with the output shaft through a transmission mechanism in the transmission case, and the output shaft is detachably connected with the rolling brush. Therefore, in the mounting and dismounting processes of the driving assembly, only the transmission case needs to be mounted and dismounted, and the mounting and dismounting of the driving assembly can be more convenient.

Also, the diameter of the fifth transmission gear 222 is larger than that of the sixth transmission gear 223. In addition, the fifth transmission gear 222 is in transmission connection with the second rolling brush through a spline.

In operation, for first transmission 21, drive gear 31 meshes with counter gear 26 to transmit torque generated by drive assembly 30, and counter gear 26 meshes with first transmission gear 211 to transmit torque to first transmission gear 211. The third transmission gear 213 rotates synchronously with the first transmission gear 211, and transmits the torque to the second transmission gear 212 through the first belt transmission member 214. The second transmission gear 212 is in transmission connection with the first rolling brush through a spline, so that the first rolling brush can be driven to rotate, and the cleaning effect of the first rolling brush is achieved.

Meanwhile, with the second transmission mechanism 22, the driving gear 31 is engaged with the fourth transmission gear 221, and transmits the torque generated by the driving assembly 30 to the fourth transmission gear 221. And sixth transfer gear 223 rotates in synchronism with fourth transfer gear 221 and transfers torque to fifth transfer gear 222 through second belt transfer member 224. The fifth transmission gear 222 is in transmission connection with the second rolling brush through a spline, so that the second rolling brush can be driven to rotate, and the cleaning effect of the second rolling brush is achieved. In the process, the reversing gear 26 is in transmission fit with the first transmission mechanism 21, so that the rotating directions of the first rolling brush and the second rolling brush are opposite, and the cleaning effect achieved by the floor brush assembly 100 is better.
