         2 . The maintenance station of  claim 1 , further comprising a bottom wall; wherein the dirt receiving component is detachably positioned on the bottom wall, the dirt receiving component comprises a first connection part, the base comprises a second connection part, and the first connection part engages with the second connection part, such that the dirt receiving component is detachably connected to the base. 
     
     
         3 . The maintenance station of  claim 1 , wherein the dirt receiving component is plate-shaped, and a center part of the dirt receiving component is concave to form the sewage collection chamber. 
     
     
         4 . The maintenance station of  claim 1 , wherein the dirt receiving component and the base form a sliding pair. 
     
     
         5 . The maintenance station of  claim 4 , wherein the base comprises a slotted guide, and the slotted guide comprises a front end face and a rear end face;
 the dirt receiving component comprises:
 a base plate; 
 a guide rail engaged with the slotted guide, the guide rail capable of extending through the front end face and the rear end face, the guide rail protruding from the base plate and capable of blocking the sewage from flowing out from a side edge of the base plate; 
 a front baffle plate protruding from the base plate to prevent the sewage from flowing out from a front edge of the base plate; and 
 a rear baffle plate positioned on the cleaning container and abutting against the rear end face; 
   when the dirt receiving component slides into a use state where the base plate abuts against the rear baffle plate, the front baffle plate abuts against the front end face, thereby forming the dirt receiving component capable of blocking the sewage from flowing out from all the side edges of the base plate.   
     
     
         6 . The maintenance station of  claim 1 , wherein the cleaning container comprises a protrusion part configured to scrub and clean the cleaning component of the cleaning robot. 
     
     
         7 . The maintenance station of  claim 6 , wherein the protrusion part comprises a plurality of ribbed plates. 
     
     
         8 . The maintenance station of  claim 7 , wherein each ribbed plate comprises a plurality of bumps. 
     
     
         9 . The maintenance station of  claim 7 , wherein a cross-section of each ribbed plate is in curved shape and is convex in a middle of each ribbed plate. 
     
     
         10 . The maintenance station of  claim 9 , further comprising a water inlet pipe, an end of the water inlet pipe configured to be connected to an external water supply, another end of the water inlet pipe connected to at least one ribbed plate, wherein the at least one ribbed plate connected to the water inlet pipe is hollow and defines a plurality of through holes for spraying water towards the cleaning component. 
     
     
         11 . The maintenance station of  claim 1 , further comprising a drainage pipe and a sewage tank, wherein the drainage pipe comprises:
 a detachable part communicating with the sewage collection chamber; and   a fixed part, an end of the fixed part detachably connected to the detachable part, and another end of the fixed part connected to the sewage tank.   
     
     
         12 . The maintenance station of  claim 11 , further comprising a filtering structure positioned on an end of the detachable part connected to the sewage collection chamber. 
     
     
         13 . The maintenance station of  claim 12 , further comprising a water feeding mechanism configured to convey clean water to the cleaning container. 
     
     
         14 . The maintenance station of  claim 13 , wherein the water feeding mechanism comprises:
 a water inlet pipe, an end of the water inlet pipe communicated with the cleaning container, another end of the water inlet pipe configured to be connected to an external water supply;   a magnetic valve connected to the water inlet pipe; and   a controller electronically connected to the magnetic valve.   
     
     
         15 . The maintenance station of  claim 1 , wherein the base comprises a cavity, and the maintenance station further comprises:
 a cleaning plate positioned in the cavity, the cleaning plate and the cavity being cooperative to form the cleaning container;   a clean water nozzle positioned in the cleaning container and facing the cleaning component, and the clean water nozzle communicating with the water inlet pipe; and   a sewage outlet positioned on the cleaning plate and communicating with the sewage collection chamber.   
     
     
         16 . The maintenance station of  claim 15 , wherein the cleaning plate comprises wheel fixing grooves for receiving running wheels of the cleaning robot. 
     
     
         17 . The maintenance station of  claim 15 , wherein the cleaning plate defines a plurality of drain holes which form the sewage outlet, and the drain holes communicates with the sewage collection chamber and are positioned over the sewage collection chamber.
