The pressure sensor is controlled to a controller and the controller is connected to an alarm. Power supplies to the pressure sensor, the controller and the alarm are all carried out through a power supply module. By means of arrangement of the alarm in the swimming ring, an alarm can be sent timely during air leakage of the swimming ring, thereby reducing the accidents caused by air leakage of the swimming ring.
