Then, the entire safety valve 1 is removed from the water inlet 22 of the heating chamber 21 of the steam cleaner 2 (see FIG. 3). When the water in the heating chamber 21 is heated and boiled using the steam cleaner 2 to generate steam pressure, the steam pressure enters through the air inlet 112 at the bottom end of the screwing main body 11 and the inner valve sleeve 12 Through the central through-hole 121, and enters the pressure detecting mechanism 16, and pushes up the elastic diaphragm 162 therein, whereby the pushing-up means 163 is pushed up to push up the clutch means 17, and the bottom end periphery of the clutch means 17 The convex claw portion 172 is separated from the concave portion 151 on the peripheral edge of the driving rotary disk 15 by this. At this time, when rotating the rotary knob cover 18 to rotate the clutch means 17, the screwing main body 11 cannot be interlocked and rotated, the idle state is exhibited, the safety valve 1 cannot be removed, and the boiling steam Dangerous situations caused by spouting can be prevented (see Fig. 4). When the steam pressure in the heating chamber 21 continues to increase and becomes larger than the thrust of the spring 124, the inner valve sleeve 12 is pushed upward by the steam pressure, so that the bottom end of the inner sleeve 12 is at the bottom end of the screwing main body 11. The steam is released from the inlet 112 and leaks from the leak pressure hole 113 of the screwing main body 11, releasing an excessive pressure, thereby maintaining the safe steam pressure value of the heating chamber 21 (see FIG. 5). In addition, a seal ring 19 provided with a sleeve ring 191 is provided on the middle outer edge of the screw main body 11 to achieve a sealing effect when the safety valve 1 is screwed into the water inlet 22 of the heating chamber 21. .
