The fire sprinkler for firefighting can change the spray range and improve the applicability of the sprinkler by setting the sprinkler assembly, and the glass body can be protected by setting the protective assembly;

[0004] However, the use of motors in the above patents will greatly increase the cost and installation difficulty, and also require power supply lines or power supply batteries. In addition, the splashing of glass slag has not been improved. Moreover, the nozzles of the existing patents are disposable, which is costly, and after the fire is extinguished, the water pipe valve needs to be manually closed to cut off the water supply, which is very wasteful of water.

[0005] And after the valve is manually closed, if the fire breaks out again, the fire sprinkler will be completely ineffective, posing a huge safety hazard. Utility Model Content
