[0004] With the continuous development of technology, cleaning equipment such as floor scrubbers and sweeping and mopping machines have been widely adopted by households. Floor scrubbers save time and effort compared to traditional manual cleaning. Floor scrubbers are used to clean the floor.

[0005] In related art floor scrubbers, the floor-reaching part is a floor brush. A motor is mounted on the base of the floor brush, which drives the roller brush through a transmission element. This causes the motor to occupy space in the water tank. Simultaneously, the water pump is placed to one side of the motor, also occupying space in the water tank. This results in a smaller volume in the lower part of the water tank. The only way to increase the volume is by increasing the height of the water tank, which is unsightly and raises the center of gravity. Furthermore, the placement of the motor and water pump at the bottom of one side of the water tank results in uneven weight on the left and right sides of the base, affecting the stability of the floor scrubber during operation.

[0043] FIG1 shows a schematic diagram of a floor brush of a floor scrubber in the related art.

[0044] As shown in Figure 1, in the related art, the floor brush 200, motor 210, water pump 220, and circuit of the floor scrubber are all arranged on the base 230. The motor 210 drives the roller brush 240 through the transmission member, causing the motor 210 to occupy the space of the clean water tank. At the same time, the water pump 220 is also placed on one side of the motor 210, which also occupies the space of the clean water tank. As a result, the volume of the lower part of the clean water tank is small, and the volume can only be increased by increasing the height of the clean water tank, which will cause problems such as unsightly appearance and raised center of gravity. At the same time, in order to facilitate the layout of the circuit, the powered equipment is placed in one place as much as possible. Placing the motor 210 and water pump 220 at the bottom of one side of the clean water tank will cause the weight of the base 230 to be uneven, affecting the stability of the floor scrubber during operation.

[0045] The present disclosure provides a floor brush 100, a cleaning device, and a cleaning system. The floor brush 100 may include: a base 120, the base 120 including a water tank 121 configured to receive a fresh water tank 130; a roller brush 110 rotatably mounted at one end of the base 120, the roller brush 110 having an internal accommodating chamber; and a drive device disposed within the internal accommodating chamber and configured to drive the roller brush 110 to rotate. The water tank 121 may include a first groove 1211 and a second groove 1212, the first groove 1211 and the second groove 1212 being arranged parallel to the axis of the roller brush 110. The floor brush 100 provided by the present disclosure has a motor (drive device) built into the roller brush 110, which can reduce space utilization on the base 120, thereby preventing the motor from occupying space in the fresh water tank 130, thereby improving space utilization and enhancing the appearance of the floor brush 100. In some embodiments, the water tank groove 121 overlaps with the roller brush 110 in the height direction of the floor brush 100. By arranging the drive device inside the roller brush 110, space can be saved for the base 120 within the height range of the roller brush 110, so that the water tank can be placed within this height range, reducing the overall height of the floor brush 100 and improving its aesthetics.

[0046] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0047] Figure 2 shows a schematic diagram of a floor brush provided according to some embodiments of the present disclosure.
