Compact-structure cleaning robot service station and cleaning system

The invention discloses a compact-structure cleaning robot service station and a cleaning system, the service station comprises a shell, a cavity is defined by the shell, and a liquid adding mechanism and a liquid discharging mechanism are arranged in the cavity. The liquid adding mechanism comprises a liquid supply pipe, the liquid discharging mechanism comprises a liquid discharging groove, the liquid supply pipe and the liquid discharging groove can be driven by corresponding driving devices to move linearly in the front-back direction, and the liquid supply pipe and the liquid discharging groove can extend out of the shell or retract into the cavity in the moving process. The liquid supply pipe supplies liquid to the cleaning robot when extending out of the shell and moving to the liquid adding position, and the cleaning robot discharges liquid only when the liquid discharging groove extends out of the shell and reaches the liquid discharging position. The driving device can convert acting force in the ve
