The water pump 8 also includes a water inlet and a water outlet. The water inlet end of the water pump 8 is connected with the clean water tank through the clean water delivery pipe 12 . The water outlet of the water pump 8 is connected with the front water delivery pipe 10 and the rear water delivery pipe 11 . When the water pump 8 works, clean water is drawn from the inside of the clean water tank and pumped to the front water delivery pipe 10 and the rear water delivery pipe 11 to realize independent water supply to the front water spray plate 301 and the rear water spray plate 302. The water pump 8 has an axis extending along the water inlet end and the water outlet end, and the axis is perpendicular to the first rolling brush 201 and/or the second rolling brush 202 , so that the water pump 8 can be placed in the inner space of the brush housing 3 fully.

The inside of the water pump 8 is also provided with a control circuit board, which can be used to change the working power of the water pump 8, and then adjust the amount of clear water pumped to the front water delivery pipe 10 and the rear water delivery pipe 11. When the operating power of the water pump 8 is larger, the clear water pumping volume to the front water delivery pipe 10 and the rear water delivery pipe 11 is also larger, correspondingly, the water spray volume of the front water spray plate 301 and the rear water spray plate 302 is also larger;

At least one solenoid valve 9 is disposed in the water flow path of at least one of the front water delivery pipe 10 and the rear water delivery pipe 11 . The solenoid valve 9 can change the amount of water delivered inside the front water delivery pipe 10 and/or the rear water delivery pipe 11 by adjusting its own valve opening. When the valve of electromagnetic valve 9 was in fully closed state, the inside of front water delivery pipe 10 and/or rear water delivery pipe 11 would not deliver water at all, and now front water spray plate 301 and/or rear water spray plate 302 were in the state of stopping water spray. When the valve of the electromagnetic valve 9 is in a fully open state, the water transfer volume inside the front water delivery pipe 10 and/or the rear water delivery pipe 11 reaches the maximum value, and now the front water spray plate 301 and/or the rear water spray plate 302 roll the brush forward and/or the back roll brush to spray water with the maximum amount of water spray. When changing the valve opening value of the electromagnetic valve 9, the water delivery volume inside the front water delivery pipe 10 and/or the rear water delivery pipe 11 will also change accordingly.

Continuing to refer to FIG. 2 , the water spray mechanism further includes a three-way adapter 14 . The tee adapter 14 includes a water inlet and two water outlets. The water inlet end of the three-way adapter 14 is connected with the water outlet of the water pump 8; one water outlet of the three-way adapter 14 is connected with the front water spray plate 301 and/or the rear water spray plate 302, and the other water outlet of the three-way adapter 14 is connected with the water inlet of the solenoid valve 9. The three-way adapter 14 divides the output waterway of the water pump 8 into two, and delivers clean water to the front water spray plate 301 and the rear water spray plate 302 respectively.

One end of the clean water delivery pipe 12 is connected with the water inlet end of the water pump 8, and the other end passes through the rotating shaft structure 4 and is connected with the clean water tank. When the ground brush cleans the ground, the rotating shaft structure 4 drives the ground brush to rotate on the horizontal plane, and the clean water delivery pipe 12 will also rotate synchronously, effectively avoiding the bending of the clean water delivery pipe 12 and affecting the normal extraction of clean water by the water pump 8 from the clean water tank.

Please refer to FIG. 3 to FIG. 7 , which respectively provide different structural schematic diagrams of the water delivery pipeline inside the floor brush of the present application.

As shown in FIG. 3 , a solenoid valve 9 is provided in the water flow path of the rear water delivery pipe 11 for adjusting the water flow of the rear water delivery pipe 11 .

As shown in FIG. 4 , a solenoid valve 9 is provided in the water flow path of the front water delivery pipe 10 for adjusting the water flow of the front water delivery pipe 10 .

As shown in FIG. 5 , solenoid valves 9 are respectively arranged in the water flow paths of the front water delivery pipe 10 and the rear water delivery pipe 11 to adjust the water flows of the front water delivery pipe 10 and the rear water delivery pipe 11 respectively.

As shown in FIG. 6 , no electromagnetic valve 9 is provided in the water flow paths of the front water delivery pipe 10 and the rear water delivery pipe 11 , and the clear water output from the water outlet of the water pump 8 is directly used to supply water to the front water delivery pipe 10 and the rear water delivery pipe 11 after being diverted by the three-way adapter 14 .

As shown in FIG. 7 , neither the solenoid valve 9 is set in the water flow path of the front water delivery pipe 10 nor the rear water delivery pipe 11 , and the clear water output from the water outlet of the water pump 8 passes through the solenoid valve 9 and the three-way adapter 14 in turn to supply water to the front water delivery pipe 10 and the rear water delivery pipe 11 , so that the solenoid valve 9 can synchronously adjust the water flow of the front water delivery pipe 10 and the rear water delivery pipe 11 .
