         5 . The washing tray according to  claim 3 , wherein the sewage trough spirals from the sewage outlet in a shape of an Archimedean spiral. 
     
     
         6 . The washing tray according to  claim 1 , wherein the washing structure further comprises washing ribs arranged at intervals to form the sewage trough, and each washing rib has a plurality of protrusions configured to contact with the cleaning member. 
     
     
         7 . The washing tray according to  claim 1 , wherein two washing structures are symmetrically arranged, and each washing structure corresponds to one sewage outlet. 
     
     
         8 . The washing tray according to any one of  claim 1 , wherein the tray body comprises a recessed portion, a width of the recessed portion decreases along a recessing direction, the sewage outlet is located at a lowest position of the recessed portion, and the washing structure is located within the recessed portion; and
 the washing tray comprises a water inlet communicating with the sewage trough and a height of the sewage trough gradually decreases along a flow direction of sewage, so that the water inlet is higher than the sewage outlet.   
     
     
         9 . The washing tray according to  claim 8 , wherein an inner surface of the recessed portion forms a side surface of a truncated-cone cavity. 
     
     
         10 . A docking station, comprising a washing tray,
 wherein the washing tray comprises a tray body, and a washing structure and a sewage outlet both arranged at the tray body, wherein:   the washing structure comprises a sewage trough; and   the sewage outlet communicates with the sewage trough and is surrounded by the washing structure, so that in a case that the washing tray washes a cleaning member, the sewage outlet and the washing structure both are configured to be located below the cleaning member.   
     
     
         11 . A cleaning system, comprising:
 a docking station, wherein the docking station comprises a washing tray, wherein the washing tray comprises a tray body, and a washing structure and a sewage outlet both arranged at the tray body, wherein the washing structure comprises a sewage trough; and the sewage outlet communicates with the sewage trough and is surrounded by the washing structure, so that in a case that the washing tray washes a cleaning member, the sewage outlet and the washing structure both are configured to be located below the cleaning member; and   a cleaning device, wherein the cleaning device comprises a drive component and a cleaning member, and in a case that the cleaning device successfully docks with the docking station, the drive component drives the cleaning member, so that the cleaning member rubs against the washing structure to be washed.   
     
     
         12 . The cleaning system according to  claim 11 , wherein the docking station comprises a hot air component, a water supply component and a valve, and the valve communicates with the sewage trough;
 in a case that the valve switches to communicate the sewage trough with the water supply component, the water supply component delivers water to the sewage trough; and   in a case that the valve switches to communicate the sewage trough with the hot air component, the hot air component delivers hot air to the washing structure to dry the cleaning member.   
     
     
         13 . The cleaning system according to  claim 11 , wherein the drive component drives the cleaning member to rotate to rub against the washing structure, and in a case that a circle formed by the rotation of the cleaning member is taken as a reference circle, a distance between a center of the sewage outlet and a center of the reference circle in a radial direction of the reference circle is denoted as d, and a radius of the reference circle is denoted as D, and 0≤d/D≤3/5. 
     
     
         14 . The cleaning system according to  claim 11 , wherein an area of a cross-section of the sewage trough gradually decreases along a flow direction of sewage, and the cross-section of the sewage trough is perpendicular to the flow direction of the sewage. 
     
     
         15 . The cleaning system according to  claim 11 , wherein the sewage trough spirals around the sewage outlet with the sewage outlet serving as an origin. 
     
     
         16 . The cleaning system according to  claim 11 , wherein a plurality of sewage troughs converge at the sewage outlet.
