Claim 9:
10. The base station as claimed in claim 9, wherein the first water tank has a water inlet and a water outlet both communicated with the water storage cavity, the reversing valve is respectively connected to the negative pressure interface, the positive pressure interface, the vent, and atmospheric environment;
wherein when the negative pressure interface, the reversing valve and the vent are communicated, and the positive pressure interface and the reversing valve are communicated to the atmospheric environment, negative pressure is formed inside the water storage cavity of the first water tank for the water storage cavity of the first water tank to store water through the water inlet;
when the positive pressure interface, the reversing valve and the vent are communicated, and the negative pressure interface and the reversing valve are communicated to the atmospheric environment, positive pressure is formed inside the water storage cavity of the first water tank for the water storage cavity of the first water tank to discharge water through the water outlet.
