The water spraying mechanism and the motor 5 are respectively arranged on the left side and the right side of the axis of the rolling brush, so that the space utilization rate inside the shell 1 is improved, and the pipelines of the water spraying mechanism and the lines of the motor 5 are prevented from being wound.
The water spraying mechanism is used for spraying water to the front rolling brush 2 and the rear rolling brush 3 for wetting, so that the front rolling brush 2 and the rear rolling brush 3 can clean the ground in a wet mode. The water spraying mechanism comprises a front water spraying plate 6, a rear water spraying plate 7, a water pump 8, at least one electromagnetic valve 9, a front water conveying pipe 10, a rear water conveying pipe 11 and a clear water conveying pipe 12. Be provided with fixing base 13 on the casing 1, in water pump 8 and solenoid valve 9 were fixed in casing 1 through fixing base 13, avoided the floor cleaning machine to collide or vibrate and lead to water pump 8 and solenoid valve 9 to take place to loosen and shift in the course of the work.
The front water spraying plate 6 is adjacent to the front rolling brush 2 and is used for spraying water to the front rolling brush 2; the rear water spray plate 7 is adjacent to the rear roll brush 3 for spraying water to the rear roll brush 3. The front water spray plate 6 and the rear water spray plate 7 are arranged in parallel. The front water spraying plate 6 and the rear water spraying plate 7 respectively spray water to the front rolling brush 2 and the rear rolling brush 3 independently, so that the respective wetting states of the front rolling brush 2 and the rear rolling brush 3 are guaranteed to be controlled independently on different cleaning occasions. The front and rear water spray plates 6 and 7 may have, but are not limited to, a flat plate-shaped structure, and the lengths of the front and rear water spray plates 6 and 7 are the same as the lengths of the front and rear roll brushes 2 and 3. The front water spraying plate 6 and the rear water spraying plate 7 are uniformly distributed with a plurality of water spraying ports along the length direction of the front water spraying plate and the rear water spraying plate, and each water spraying port is aligned with the front rolling brush 2 or the rear rolling brush 3. When the front water spray plate 6 or the rear water spray plate 7 pumps clean water, each water spray can spray water in alignment with a corresponding area of the front rolling brush 2 or the rear rolling brush 3, thereby ensuring that all areas of the surface of the front rolling brush 2 or the rear rolling brush 3 can be uniformly wetted by the sprayed water.

The water outlet end of the water pump 8 is connected with a front water delivery pipe 10 and a rear water delivery pipe 11. When the water pump 8 works, clear water is pumped from the clear water tank and is pumped into the front water pipe 10 and the rear water pipe 11, so that independent water supply for the front water spraying plate 6 and the rear water spraying plate 7 is realized. 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 front rolling brush 2 and/or the rear rolling brush 3, so that the water pump 8 can be placed in the inner space of the housing 1.
The inside of the water pump 8 is also provided with a control circuit board, and the control circuit board is utilized to change the working power of the water pump 8, so as to adjust the pumping quantity of the clean water to the front water pipe 10 and the rear water pipe 11. When the working power of the water pump 8 is higher, the pumping amount of the clean water to the front water delivery pipe 10 and the rear water delivery pipe 11 is also higher, and correspondingly, the water spraying amount of the front water spraying plate 6 and the rear water spraying plate 7 is also higher; on the contrary, the pumping amount of the clean water to the front water pipe 10 and the rear water pipe 11 is smaller, and accordingly, the water spraying amount of the front water spraying plate 6 and the rear water spraying plate 7 is smaller.
At least one electromagnetic valve 9 is disposed in a water flow path of at least one of the front water duct 10 and the rear water duct 11. The electromagnetic valve 9 can change the respective water delivery amount in the front water delivery pipe 10 and/or the rear water delivery pipe 11 by adjusting the opening of the valve. When the valve of the electromagnetic valve 9 is in a completely closed state, the interior of the front water pipe 10 and/or the rear water pipe 11 is completely free from water delivery, and at this time, the front water spraying plate 6 and/or the rear water spraying plate 7 is in a state of stopping water spraying. When the valve of the electromagnetic valve 9 is in a fully opened state, the water delivery amount inside the front water delivery pipe 10 and/or the rear water delivery pipe 11 reaches a maximum value, and at this time, the front water spray plate 6 and/or the rear water spray plate 7 sprays water to the front rolling brush and/or the rear rolling brush at a maximum water spray amount. When the valve opening degree of the electromagnetic valve 9 is changed, the water delivery amount inside the front water delivery pipe 10 and/or the rear water delivery pipe 11 is also changed correspondingly, and at the moment, the water spray amount of the front water spray plate 6 and/or the rear water spray plate 7 is also changed synchronously, so that the water spray amount ratio of the front water spray plate 6 to the rear water spray plate 7 can be controlled, and the front rolling brush 2 and the rear rolling brush 3 realize different water spray wettability.
With continued reference to fig. 1, the water spray mechanism further includes a three-way adapter 14. The three-way adapter 14 includes a water inlet end and two water outlet ends. The water inlet end of the three-way adapter 14 is connected with the water outlet end of the water pump 8; one water outlet end of the three-way adapter 14 is connected with the front water spraying plate 6 and/or the rear water spraying plate 7, and the other water outlet end of the three-way adapter 14 is connected with the water inlet end of the electromagnetic valve 9. The three-way adapter 14 divides the output water path of the water pump 8 into two parts, and respectively conveys clean water to the front water spraying plate 6 and the rear water spraying plate 7.
One end of the clear water conveying pipe 12 is connected with the water inlet end of the water pump 8, and the other end of the clear water conveying pipe penetrates through the rotating shaft structure 4 to be connected with the clear water tank. When the floor brush cleans the ground, the rotating shaft structure 4 drives the floor brush to rotate on the horizontal plane, and simultaneously, the clear water conveying pipe 12 can synchronously rotate, so that the clear water conveying pipe 12 is effectively prevented from being bent to influence the normal clear water extraction of the water pump 8 from the clear water tank.
Please refer to fig. 2 to fig. 6, which respectively provide different structural schematic diagrams of the water conveying pipeline inside the floor brush of the present application.
