[0014] (III) Beneficial Effects

[0015] This utility model provides a high-efficiency fire extinguishing sprinkler head, which has the following beneficial effects:

[0016] 1. This high-efficiency fire extinguishing sprinkler head, through the design of a retaining ring, support frame, and telescopic component, allows for easy disassembly and assembly of the sprinkler head when the connection joint needs to be disassembled. Pressing the support frame compresses the support spring, causing the positioning rod to slide within the sliding hole on the support frame. This, in turn, pushes the retaining ring to slide within the fixed ring, disengaging the retaining ring from the slot on the connection joint and pulling the connection joint. This achieves convenient sprinkler head disassembly and assembly without the need for special tools, significantly reducing maintenance or replacement time and improving efficiency.

[0017] 2. This high-efficiency fire-fighting sprinkler head, through the setting of rotating components and a splash plate, when a fire occurs, the heat-sensitive glass tube ruptures due to heat, causing the baffle to detach. High-pressure water jets from the bottom of the connecting joint rush out. When the water jet impacts the splash plate, the guide vanes cut the water jet to form multi-directional atomized water droplets. At the same time, the impact of the water jet drives the splash plate to rotate. Since the connecting pipe is fixed on the inner ring of the rotating bearing, the splash plate is driven to rotate according to the water pressure, thereby expanding the spray range. The rotating water jet forms a continuous water film, effectively isolating flames from combustibles, and reducing the temperature of the fire scene by absorbing heat over a large area, thus suppressing the risk of reignition.
