Referring also to fig. 1-2, the present invention provides embodiments of a fire suppression system that produces a continuous vortex ring.
As shown in fig. 1-2, the fire suppression system of the present invention for generating a continuous vortex ring comprises:
The cavity system 4 is internally provided with a cavity, wherein the cavity is provided with a first opening and a second opening, and the second opening is a narrow-down opening;

It should be noted that the motion of the motion system 3 is periodic vibration, so that the air in the cavity system 4 is sucked and supplemented by the second opening after being pushed out, and the goal of stably generating vortex ring pulse for a long time is realized by the cyclic reciprocation. And because the second opening of the cavity system 4 is a narrowing opening, the diameter of the second opening is smaller, the space dissipation of the vibration kinetic energy of the motion system 3 is reduced, and the kinetic energy of the motion system is more concentrated and used for generating the vortex ring, so that the stability and the long-distance transmission capability of the vortex ring are improved. Thereby ensuring the vortex ring to have longer stable propagation distance and achieving the effect of remote fire extinguishment.
When extinguishing fire, the second opening of the cavity system 4 is required to be aligned with a target fire source, then the motion system 3 is driven to vibrate back and forth in the cavity system 4 periodically, and air in the cavity system 4 is continuously pushed out of the cavity through the second opening, and then is inhaled for supplement; after the air exits the second opening, the air is rolled up to form a vortex ring due to the shearing action of the edge of the second opening. When the vortex ring reaches the target fire source, the stretching rate of target flame can be increased to a critical state due to the high annular quantity characteristic of the vortex ring structure, so that the target fire source is extinguished, and the aim of extinguishing fire is fulfilled.

The control system has the function of adjusting output voltage, thereby controlling the vibration frequency of the motion system and adjusting the interval between two adjacent vortex ring pulses (namely the generation frequency of the vortex ring pulses). Specifically, by adjusting the output voltage of the control system 1, the operating frequency of the power system 2 can be adjusted, and thus the distance between two adjacent vortex ring pulses 5 (i.e., the frequency of generation of the vortex ring pulses) can be adjusted.
In a preferred implementation of the embodiment of the present invention, as shown in fig. 1, the diameter of the second opening is 1/4 to 1/2 of the diameter of the first opening.
Specifically, the diameter of the second opening is 1/4-1/2 of the diameter of the first opening, and the diameter of the second opening can be adjusted as required. The diameter of the second opening is gradually reduced to form a truncated cone shape. Of course, the shape of the side wall at the second opening can also be adjusted according to the requirement, for example, the section of the side wall at the second opening is in a straight line shape or an arc shape. The center of the first opening is taken as the sphere of the sphere center, the side wall of the second opening is tangent to the sphere, and the tangent point is positioned in the middle of the side wall of the second opening, so that vortex flow is formed in the cavity, and the vortex ring structure is formed outside the second opening.
