A receiving groove 404 corresponding to the nozzle groove 5 is provided on the outer wall of the device shell 401. An adjustment plate 405 is slidably provided in the receiving groove 404. A strip-shaped positioning hole 406 communicating with the receiving groove 404 is provided on the inner wall of the device shell 401. The bottom of the adjustment plate 405 extends horizontally and moves through the strip-shaped positioning hole 406. A micro linear actuator 407 is also provided inside the device shell 401. The micro linear actuator 407 is electrically connected to the terminal control structure 402. A driving rod 408 is provided at the end of the micro linear actuator 407. The driving rod 408 is connected to the extending end of the corresponding strip positioning hole 406. The bottom of the device housing 401 is provided with an anti-misoperational smoke detection structure electrically connected to the terminal control structure 402, the assembly positioning seat 1 and the rotating column 2 are an integrated structure, the assembly positioning seat 1 is provided with a bearing 8 rotatably connected to the rotating column 2, the pressure sensor 403 is electrically connected to the terminal control structure 402, the anti-misoperational smoke detection structure includes a U-shaped smoke channel 409, a temperature sensor 410, and a miniature double-headed electric valve 411, the U-shaped smoke channel 409 has an air inlet and an air outlet facing downward, the temperature sensor 410 is connected to the terminal control structure 402 by wireless signals, the miniature double-headed electric valve 411 is arranged between the air inlet and the air outlet, and both ends are provided with a connection between the air inlet and the air outlet. The valve flap for closing the air outlet is provided. A micro fan 412 is provided in the middle of the top of the U-shaped smoke channel 409. A smoke concentration sensor 413 is provided above the micro fan 412. A detection rod 414 is provided at the end of the smoke concentration sensor 413, which extends into the air outlet. The temperature sensor 410 is used to detect the external temperature. The terminal control structure 402 consists of a circuit board, a power supply module, a storage module, a wireless module, a data processing module, and a control module. When the smoke concentration sensor 413 described in this application detects a smoke value of 10% obs / m~15% obs / m for 1 to 3 seconds, the data is transmitted to the terminal control structure 402. The existing smoke concentration sensor 413 is 5% obs / m~15% obs / m.The terminal control structure 402 controls the water output operation through the fire extinguishing system. When the adjusting plate 405 moves upward, it will block the input port of the corresponding nozzle slot 5, making the diameter of the input port of the nozzle slot 5 smaller. The terminal control structure 402 has the functions of charging and power supply.

[0021] During operation, when a fire breaks out indoors, the temperature sensor 410 detects the excessive temperature and sends a signal to the terminal control structure 402. The terminal control structure 402 first controls the micro double-headed electric valve 411 to release the restriction on the U-shaped smoke passage 409, and then controls the micro fan 412 to operate, sucking the indoor air into the U-shaped smoke passage 409 from the air inlet and discharging it from the air outlet. During this process, the smoke concentration sensor 413 detects the smoke concentration in the air. This structure is to prevent the smoke generated after some small fires are extinguished in time from rising to the detection range, and then causing the sprinkler to work after the fire. The smoke sucked by the air extraction structure will be further concentrated. Therefore, the detection value starting point of the smoke concentration sensor 413 in this application is higher than that of the existing smoke concentration sensor 413. The smoke generated after the small fire is extinguished in time cannot reach the detection value starting point of the smoke concentration sensor 413 in this application. Therefore, the terminal control structure 402 will not control the fire extinguishing system to carry out the water output operation;

[0022] When the concentration reaches, the terminal control structure 402 controls the fire extinguishing system to carry out the water output operation. The water flow enters the rotating column 2 through the assembly positioning seat 1 and then is sprayed out by the nozzles 6 on the nozzle slot 5. Due to the inclined setting of the multiple nozzle slots 5, the rotating column 2 will be subjected to a force and rotate, greatly increasing the spraying range, effectively solving some dead corners covered by the current sprinklers, making the water mist spraying coverage more uniform. At the same time, once a certain nozzle 6 is blocked, due to the rotating effect of the sprinkler, it can effectively solve the loss caused by the blocked sprinkler and the inability to protect the protected area or extinguish the fire. The pressure sensor 403 will detect the water pressure. When the water pressure is too low, the terminal control structure 402 will control the micro linear actuator 407 to operate. The micro linear actuator 407 drives the drive rod 408 to move linearly upward, so that the drive rod 408 drives the adjusting plate 405 to block the input port of the corresponding nozzle slot 5, reducing the diameter and increasing the water output pressure, effectively compensating for the pressure;

[0023] The filter screen 7 is arranged at the inner end of the nozzle 6, not the outer end of the nozzle 6, effectively avoiding the blockage of the filter screen 7 caused by pipelines or other factors, resulting in the inability of the sprinkler to work.

[0024] The foregoing has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
