Claim 7:
8. The base station as claimed in claim 7, wherein the gas source system comprises a gas pump and a reversing valve communicated with the gas pump and the vent of the first water tank, the gas pump and the reversing valve are both arranged on the base station body, and the base station body is provided with at least one interface;
the vent is communicated with the reversing valve through the interface;
the reversing valve is configured to switch the communication at the interface to form a negative pressure gas circuit or a positive pressure gas circuit in case the negative pressure gas circuit is formed, gas in the water storage cavity is allowed to flow into the gas pump through the interface, the reversing valve, and a gas inlet of the gas pump successively to cause the water storage cavity to be in the negative pressure state; and in case the positive pressure gas circuit is formed, gas is allowed to flow into the interface through a gas outlet of the gas pump and the reversing valve successively to cause the water storage cavity to be in the positive pressure state.
