The spray head 22 adopts an intelligent control spray head, and the spray head 22 comprises two sets of trigger devices, namely a traditional temperature passive trigger switch and an active starting device of an information transmission device. The traditional temperature passive trigger switch has the following working principle: when the ambient temperature rises to reach the fire alarm value, the thermal expansion material 35 in the lower cavity of the spray head senses high temperature and expands by heating, and the thermal expansion material extrudes upwards and pushes the push rod 31 to rise, pushes the clamping seat 56 and drives the cover plate 28 to move upwards together until the groove 54 on the push rod 31 is clamped into the lock pin 33 to stop.

When the information transmission device is actively started, the working principle of the device is as follows: when a fire has occurred, but because the spray head 22 is located far from the fire source, the thermal expansion material 35 in the lower cavity of the spray head 22 does not work by thermal expansion, but the concentration values of the temperature and smoke in the environment reach the early warning values set by the temperature sensor and the smoke sensor. The information transfer device will transmit the information to the heater 34 for heating, and the information transfer device will transmit the information to the central control, which will combine the data with the BIM to form a real-time fire cloud after receiving the information. The thermally expansible material 35 in the lower end chamber of the nozzle 22 is thermally expanded. The procedure is then the same as for the first principle.

The role of the two contacts 32 in fig. 6: if there is no fire, the sprinkler head 22 is checked to see if there is water leakage, and if there is water accumulated on the splash plate, the two contacts 32 are connected to indicate that there is a fire. When a fire occurs, it is judged whether the sprinkler 22 is actively or passively operated. When the nozzle 22 is actively operated, two feedback signals are generated (one is a working signal sent by the information transmission device to the nozzle, and the other is a signal fed back to the information transmission device after the contact is triggered after the nozzle sprays water), so that only one working signal is generated when the nozzle is passively operated (after the nozzle sprays water, a signal fed back to the information transmission device after the contact is triggered). The motor 37 and the lock pin 33 are connected by a high-temperature-resistant nylon material, after the fire is extinguished, a command is issued by the central controller, the motor 37 drives the lock pin 33 to retract, and the push rod automatically falls down, so that the aim of repeated use is fulfilled.
