Technical problems to be solved: The parts of the above fire sprinkler are complex, difficult to assemble and difficult to install, which not only increases the assembly time but also increases the manufacturing cost; In addition, the most important fusible ring parts of the fire sprinkler head are installed inside the sprinkler head and fixed by other parts. Therefore, when a fire source occurs, the fusible ring parts inside are not heated first. However, the hook cover 5 1 and the screw 5 4 located at the outermost side are the most directly heated. This causes the fusible ring 5 7 to receive heat, so the sensitivity is reduced and the induction is slowed. It takes about 6 when it melts. Only 0 seconds will loosen the parts and the nozzle of the sprinkler head will open and produce water spraying effect. Although 60 seconds is a short period of time, it is enough to make the fire spread rapidly and cause more difficult losses. Secondly, the nozzle of the water nozzle 1 is closed by the water stop device 2. When it is moved or shaken, it will become loose, which will cause the water stop device 2. There is: the nozzle of the water head 1 at this time is adjusted by the installer to turn the body The lifting and lowering of the water stop device 2 closes the nozzle of the sprinkler head 1. Only the stopper 2 closes the nozzle of the sprinkler head 1 with the valve plug 2 3, and the valve plug 7 device will still be connected with the nozzle under the support of the extreme pressure. If there is a clearance, the valve plug 2 3 can be fitted with the nozzle only by further fine-tuning the water stop device 2. However, the main body 4 has been fitted with the sprinkler head 1 to the bird's second port to generate gas. The water stop device 2 is further adjusted, and since there is no Λ function, the air-tight effect cannot be achieved. In order to achieve the fine adjustment, in view of the above, how to shorten the heating time of the sprinkler head
