the left side of the middle part of the water tank (2) is connected with the supporting cylinder (111);
the left side of the supporting cylinder (111) is connected with the second supporting frame (112);
the middle part of the second support frame (112) and the inside of the support cylinder (111) are connected with the second piston (113) in a sliding mode, and the water vapor pushes the second piston (113) to move to the left to stop the support cylinder (111) no longer through the fact that the internal pressure of the water tank (2) is higher than the external pressure, so that the internal pressure of the water tank (2) is released, and explosion caused by overlarge pressure is prevented;
and the middle part of the second piston (113) is sleeved with the second compression spring (114), and two ends of the second compression spring (114) are respectively connected with the right side of the second support frame (112) and the right side of the second piston (113).
