Description

Technical Field

[0001] The utility model relates to the field of fire extinguishers, in particular to an automatic fire extinguisher. Background Art

[0002] The suspended dry powder fire extinguishing device is equipped with a temperature-sensitive glass ball at the nozzle of the sprinkler head. Under normal circumstances, the upper end of the glass ball presses against the sealing piece at the nozzle. When a fire breaks out, the temperature rises, and the liquid in the glass ball automatically expands and breaks due to the heat, and the sealing piece automatically falls off. The dry powder in the fire extinguishing device is sprayed out from the nozzle under the action of nitrogen to extinguish the fire.

[0003] In the prior art, a utility model patent with publication number CN 215309905 U proposes an automatic fire extinguisher, which can adjust the spraying angle of the fire extinguisher through the coordinated use of a support block, a slot plate, a screw rod, a rotating block, a top plate and a knob, and can achieve installation support through the coordinated use of a ball, a vertical rod, a support plate, a plug plate, a fixed plate, a spring and a support plate, and can achieve quick installation and disassembly work, and can also effectively extinguish fire by adjusting the angle;

[0004] However, the angle adjustment operation is achieved by tightening the bolts during installation. After installation, the fire extinguisher is still in a fixed state and cannot be automatically adjusted according to the location of the fire point when a fire occurs. The operability is poor, and the height position of the fire extinguisher cannot be adjusted. A lot of fire extinguishing dry powder is wasted when spraying fire. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content
