         5 . The floor brush according to  claim 1 , wherein a height of the evenly-spreading plate in a vertical direction is higher than a height of the spraying plate in the vertical direction. 
     
     
         6 . The floor brush according to  claim 1 , wherein the sewage wiping member is disposed below the spraying plate. 
     
     
         7 . The floor brush according to  claim 6 , wherein:
 the sewage wiping member is located above the suction port;   the first sewage wiping member is close to the front suction port; and   the second sewage wiping member is close to the rear suction port.   
     
     
         8 . The floor brush according to  claim 1 , further comprising a pump, wherein:
 the pump is connected to the front spraying plate by a front water pipe;   the pump is connected to the rear spraying plate by a rear water pipe; and   at least one solenoid valve is disposed in a flow path of the front water pipe and/or the rear water pipe.   
     
     
         9 . The floor brush according to  claim 8 , wherein:
 the first rolling brush and the second rolling brush are arranged in parallel; and   the pump and the solenoid valve are disposed between the first rolling brush and the second rolling brush.   
     
     
         10 . The floor brush according to  claim 9 , wherein:
 at least one three-way adapter is disposed between the pump and the solenoid valve;   an inlet end of the at least one three-way adapter is connected to an outlet end of the pump;   one outlet end of at least one three-way adapter is connected to the front spraying plate and/or the rear spraying plate; and   another outlet end of at least one three-way adapter is connected to an inlet end of the solenoid valve.   
     
     
         11 . The floor brush according to  claim 10 , wherein the outlet end of the solenoid valve is connected to the front spraying plate and/or the rear spraying plate. 
     
     
         12 . The floor brush according to  claim 1 , wherein:
 the spraying plate is assembled by a first spraying plate assembly and a second spraying plate assembly;   the first spraying plate assembly has a first flow channel defined on a side thereof, and a plurality of spraying ports defined on a side wall thereof, the plurality of spraying ports being in communication with the first flow channel and evenly arranged at intervals in an axis direction of the rolling brush; and   the second spraying plate assembly has a second flow channel defined on a side thereof facing towards the first spraying plate assembly, and an inlet port defined on a side wall thereof, the inlet port being in communication with an inlet end of the second flow channel.   
     
     
         13 . The floor brush according to  claim 12 , wherein:
