For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.
Referring to fig. 1, 2 and 3, an embodiment of the present invention provides a fire extinguishing nozzle 100 including a first discharge head 10 and a second discharge head 20 connected to each other. The first discharging head 10 includes a first feeding hole 11, a first discharging hole 12, and a first discharging channel 13 connected therebetween. The second discharging head 20 is located at one side of the first discharging head 10, and includes a second feeding hole 21, a second discharging hole 22 and a second discharging channel 23 communicated therebetween. The first feeding hole 11 is connected with the second feeding hole 21, and the first discharging hole 12 and the second discharging hole 22 are arranged in a manner of deviating from each other.
Specifically, the first feeding hole 11 and the second feeding hole 21 are both communicated with the nozzle of the fire extinguishing apparatus 1000, and the opening direction of the first feeding hole 11 is the spraying direction of the fire extinguishing agent, and the opening direction of the second feeding hole 21 is the opposite direction of the spraying direction of the fire extinguishing agent. When the fire extinguishing agent is sprayed from the spraying ports of the fire extinguishing apparatus 1000, a portion of the fire extinguishing agent is continuously sprayed in the spraying direction thereof under the guidance of the first discharge head 10, and another portion of the fire extinguishing agent is sprayed in the direction opposite to the spraying direction of the fire extinguishing agent under the guidance of the second discharge head 20.
From this, not only can put out the fire source in extinguishing device 1000 the place ahead, can also put out the fire source in extinguishing device 1000 rear or side, make extinguishing device 1000's the scope of putting out a fire bigger, the fire extinguishing agent diffusivity is better, improves extinguishing device 1000's fire extinguishing efficiency.
In some embodiments, the radial dimension of the first outlet channel 13 increases from the first inlet opening 11 to the first outlet opening 12.
In the present embodiment, the first discharging head 10 is configured as a hollow circular truncated cone structure, that is, the inner diameter of the first discharging head 10 gradually increases from the first feeding hole 11 to the first discharging hole 12. Thus, when the fire extinguishing agent is blown from the first inlet 11 to the first outlet 12, the fire extinguishing agent can be diffused under the guidance of the expanded first outlet channel 13, so that the fire extinguishing range of the fire extinguishing agent blown from the first outlet channel 13 is larger.
In some embodiments, the radial dimension of the second outlet channel 23 increases from the second inlet opening 21 to the second outlet opening 22.
Similar to the structure of the first discharge head 10, the second discharge head 20 is also configured as a hollow circular truncated cone structure, that is, the inner diameter of the second discharge head 20 gradually increases from the second feed opening 21 to the second discharge opening 22. In addition, the inner diameter of the second feeding hole 21 is matched with the inner diameter of the first feeding hole 11, so that the second discharging head 20 and the first discharging head 10 are connected with the first feeding hole 11 through the second feeding hole 21.
As can be understood, after the first discharge head 10 is connected with the second discharge head 20, the first discharge channel 13 and the second discharge channel 23 are communicated with each other and jointly form a combined channel which is small in the middle and large at two ends. When the fire extinguishing nozzle 100 is installed on the fire extinguishing apparatus 1000, the fire extinguishing agent sprayed from the nozzle is blown toward the fire extinguishing nozzle 100, wherein a portion of the fire extinguishing agent can be sprayed from the first discharging head 10 and diffused by the first discharging head 10. Another part of the fire extinguishing agent changes the spraying direction under the shielding effect of the second discharging head 20, is sprayed backwards along the extending direction of the second discharging channel 23, and is diffused under the effect of the second discharging head 20 to extinguish the fire source behind the fire extinguishing device 1000.
With the above structure, not only can the fire extinguishing agent sprayed backwards be increased, but also the fire extinguishing agent can be diffused under the guiding action of the first discharge head 10 and the second discharge head 20 of the circular truncated cone structure, and the fire extinguishing range of the fire extinguishing agent can be further enlarged.
In some embodiments, the first discharge head 10 comprises at least two guides 14, all guides 14 dividing the first discharge channel 13 in its radial direction into at least two sub-channels 15 independent of each other.
Thus, the different guides 14 can separate the fire suppressant into sets of air streams. On the one hand, the larger cross-sectional fire suppressant streams form smaller sets of streams in different guides 14, which increases the flow rate of the streams. On the other hand, the fire extinguishing agent can be guided in different directions by arranging the guide parts 14 in different directions, so that the diffusion effect of the fire extinguishing agent is better.
In some embodiments, all the guides 14 are distributed in the radial direction of the first flow channel 13 from the center to the edge, and divide the first flow channel 13 in the radial direction thereof into at least two sub-channels 15 running from the center to the edge.
In the present embodiment, the first discharging head 10 is configured as a hollow circular truncated cone structure, that is, the first discharging channel 13 is in a trumpet shape. Therefore, the guide portion 14 is provided as a multi-layer circular truncated cone structure which is sequentially distributed from the center to the edge, so that the first discharge channel 13 is divided into a plurality of horn-shaped sub-channels 15 by the multi-layer circular truncated cone structure, and the axial directions of all the sub-channels 15 are overlapped.
More specifically, the guide 14 comprises three, i.e. the first outfeed head 10 comprises a coaxial three-layer circular truncated cone structure, so that the first outfeed channel 13 is divided into three coaxial sub-channels 15. When the fire extinguishing agent is blown out from the first discharge channel 13, the fire extinguishing agent is divided into three streams, and the three streams have different diffusion ranges, whereby the diffusion efficiency of the fire extinguishing agent can be improved.
In some embodiments, the radial dimension of each sub-channel 15 increases from the first inlet 11 to the first outlet 12, i.e. each sub-channel 15 is trumpet-shaped. Thereby, the diffusion effect of the fire extinguishing agent can be effectively improved.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a fire extinguishing apparatus according to an embodiment of the present application. Based on the same concept as the fire sprinkler 100 described above, the present application provides a fire extinguishing apparatus 1000 including an apparatus body 200 and the fire sprinkler 100 as described above.

In general, the main fire source is located in front of the fire extinguishing apparatus 1000, and should be mainly extinguished in front of the fire extinguishing apparatus 1000, and a fire source in the rear or side of the fire extinguishing apparatus 1000 should be extinguished additionally. Therefore, the plurality of guide portions 14 in the first discharge head 10 can guide and spread the fire extinguishing agent in multiple directions, and thus can more efficiently extinguish the main fire source in front of the fire extinguishing apparatus 1000.
In some embodiments, the device body 200 is spaced apart from the fire-extinguishing nozzle 100 along the first direction a, and the nozzle is aligned with the second discharge hole 22 along the first direction a. That is, the nozzles of the apparatus body 200 are arranged toward the second discharge hole 22, so that the fire extinguishing agent in the accommodating space 201 can be sprayed from the nozzles and directly sprayed into the first discharge channel 13 and the second discharge channel 23, so that the fire extinguishing agent has sufficient impact force.
In some embodiments, the fire suppression apparatus 1000 further includes a plurality of connection rods 300, each connection rod 300 connecting the apparatus body 200 and the fire suppression spray head 100, all the connection rods 300 being spaced apart from each other around the nozzle.
Specifically, the connection rod 300 is connected between the nozzle of the fire extinguishing apparatus 1000 and the fire extinguishing nozzle 100, so that the fire extinguishing agent can independently move for a distance after being sprayed from the opening of the fire extinguishing apparatus 1000, and then enter the first discharging channel 13 or the second discharging channel 23. This has the advantage that the diffusion of the extinguishing medium through the first discharge channel 13 and the second discharge channel 23 can be more uniformly directed.
The utility model discloses during the specific use, connect the juncture at first feed inlet 11 and second feed inlet 21 with the one end of connecting piece 300, the other end is connected to extinguishing device 1000's exit. The fire extinguishing agent is sprayed out from the outlet, and a part of the fire extinguishing agent is sprayed out by diffusion towards the front of the fire extinguishing device 1000 under the guidance of the first discharge head 10, so as to extinguish the front main fire source. Meanwhile, the other part of the fire extinguishing agent is diffused and sprayed out from the rear of the fire extinguishing device 1000 under the guidance of the second discharge head 20, and other fire sources at the rear are extinguished.
The fire-extinguishing nozzle 100 and the fire-extinguishing device 1000 in the above embodiments have at least the following advantages:
1) the first discharging head 10 and the second discharging head 20 respectively guide the fire extinguishing agent to diffuse and spray in different directions, so that the coverage area of the fire extinguishing agent is enlarged, and the fire extinguishing efficiency of the fire extinguishing device 1000 is improved;
