A pressure-controlling appliance for an inflatable product has a inflatable body, a pump mounted in the inflatable body, a pump switch and an inflation-deflation valve. The pump inflates or deflates the inflatable bodythrough the inflation-deflation valve. The pressure-controlling appliance also comprises an inflation-deflation controlling mechanism and a pressure-controlling mechanism. The inflation-deflation controlling mechanism is applied to open and close the inflation-deflation valve and to turn the pump switch on or off. The pressure-controlling mechanism operates the inflation-deflation controlling mechanism according to the pressure in the inflatable body that compared with the high or low reference pressure.
