Claim 0:
1. A base station body, configured to be installed with a first water tank or a second water tank, a reversing valve being arranged in the first water tank, a gas pump being mounted on the base station body, wherein the base station body comprises:
a negative pressure interface, configured to communicate with a gas inlet of the gas pump;
a positive pressure interface, configured to dock with the first water tank, the positive pressure interface is provided with a gas inlet that communicates with a gas outlet of the gas pump and a docking port for docking with the first water tank, and the gas inlet communicates with the docking port;
when the first water tank is installed on the base station body, the negative pressure interface is communicated with the first water tank, and the docking port of the positive pressure interface is in an open state to connect and communicate with the first water tank; the reversing valve is configured to switch to communicate with the positive pressure interface or to communicate with the negative pressure interface; in case the reversing valve is communicated with the negative pressure interface, gas in the first water tank is allowed to flow into the gas pump through the negative pressure interface and the gas inlet of the gas pump to cause the first water tank to be in a negative pressure state; and in case the reversing valve is communicated with the positive pressure interface, gas is allowed to flow into the positive pressure interface from the gas outlet of the gas pump to cause the first water tank to be in a positive pressure state;
when the second water tank is installed on the base station body, the negative pressure interface is communicated with the second water tank, and the positive pressure interface is communicated to the atmosphere; gas is allowed to flow into the gas pump through the negative pressure interface to cause the second water tank to be in a negative pressure state.
