A glass ball sprinkler is a common type of fire sprinkler. Its heat-sensitive element is a glass ball. When the sprinkler is heated, the working fluid in the glass ball takes effect, causing the ball to burst and open.

[0003] For example, the Chinese utility model provides a "thermal induction fire sprinkler", and its announcement number is: CN218685905U, and its technical solution is: it includes a nut connecting seat, a nut base is arranged at the bottom of the nut connecting seat, a splash plate is arranged at the bottom end of the nut base, a connecting rod is fixedly connected between the nut connecting seat and the nut base, a drainage hole is arranged in the nut connecting seat, a plug is arranged at the bottom end of the drainage hole, a sealing ring is fixedly connected to the plug, a glass ball is arranged between the plug and the nut base, a vertically arranged guide rod is fixedly connected to the bottom of the plug, and the bottom end of the guide rod or the splash plate is movably connected. The beneficial effect of the thermal induction fire sprinkler is: through the guide rod fixedly arranged vertically at the bottom of the plug, the guide rod is movably connected to the splash plate, and after the glass ball breaks, the water flow pushes the plug downward, and the guide rod can prevent the plug from being lost. At this time, the plug will not affect the splashing of water around, and it is highly practical.
