Cleaning device, cleaning method thereof, and cleaning machine system

A cleaning method for a cleaning device, wherein the cleaning device comprises a water injection member configured to wet a mopping cloth of the cleaning robot, and a mopping cloth cleaning member reciprocating up and down to flap the mopping cloth of the cleaning robot, in order to clean the mopping cloth of the cleaning robot;

• wherein the water injection member comprises a water tank with an opening at an upper end;
• the mopping cloth cleaning member is a movable plate member mounted on the water tank and comprises a driving rod capable of reciprocating movement;
• wherein there is a first position where the mopping cloth cleaning member extends into the water tank and a second position where the mopping cloth cleaning member extends out of the water tank and flaps the mopping cloth of the cleaning robot, and
• the mopping cloth cleaning member reciprocates back and forth between the first position and the second position to clean the mopping cloth of the cleaning robot;
• the movable plate member further comprises a flapping plate, wherein a surface area of the flapping plate is smaller than an area of the opening of the water tank, and wherein the flapping plate is driven by an external force to move up and down;
• the water tank is provided with a movement channel throughout the water tank;
• an end of the driving rod is connected to the flapping plate, and another end of the driving rod passes through the movement channel;
• the cleaning device further comprises a sealing element configured to sealingly connect the movement channel to the driving rod;
• and
• the cleaning device further comprises a telescopic sealing element sleeved on the driving rod, wherein one end of the telescopic sealing element is sealingly connected to the flapping plate, and another end of the telescopic sealing element is sealingly connected to a surface of an inner wall of the water tank;
• wherein the cleaning method comprises:
• supplying water to the water injection member to wet the mopping cloth of the cleaning robot, when the cleaning robot is at a cleaning position of the cleaning device, and
• activating a driving mechanism to drive the mopping cloth cleaning member to reciprocate up and down.
