FIG. 1 is a schematic view of a non-pressure-storing fire extinguishing apparatus according to an embodiment of the present invention; fig. 2 is an enlarged schematic view of a portion a of the non-pressure-storage type fire extinguishing apparatus shown in fig. 1. For the purpose of illustration, the drawings show only the structures associated with embodiments of the utility model.
Referring to the drawings, an embodiment of the present invention provides a non-pressure-storage type fire extinguishing apparatus 100 including a first housing 10, a second housing 20, and an elastic sealing member 30.
The first housing 10 has a first storage chamber 11 and a nozzle 12 communicating with the first storage chamber 11, and the first storage chamber 11 stores an extinguishing agent 13. In the embodiment of the present application, the fire extinguishing agent 13 is perfluorohexanone, and in other embodiments, it may be other aqueous fire extinguishing agents, and is not limited herein.
It should be noted that when the non-pressure storage type fire extinguishing apparatus 100 is activated, the fire extinguishing agent 13 should be ejected from the ejection port 12.
It should be noted that, because perfluorohexanone is volatile at low temperature, the longer the non-pressure storage fire extinguishing apparatus 100 is left in the non-activated state, the higher the pressure in the first storage chamber 11 is, and this situation is still within the scope of the non-pressure storage fire extinguishing apparatus 100 of the present application.
The second housing 20 is connected to the first housing 10, the second housing 20 has a second storage chamber 21, the second storage chamber 21 is used for storing a gas generating agent 22, a communication hole 23 is further opened at one end of the second housing 20 facing the first housing 10, and the first storage chamber 11 and the second storage chamber 21 are communicated with each other through the communication hole 23. In the embodiment of the present application, the gas generating agent 22 is aerosol, and the aerosol can generate a large amount of gas after being ignited, so as to pressurize the first storage chamber 11 and further push the fire extinguishing agent 13 to be sprayed out of the nozzle hole 12. In other embodiments, the gas generant 22 may be other gas generants other than aerosol, and is not limited herein.
The elastic sealing member 30 is sealed at the communication hole 23, and the elastic sealing member 30 can be deformed by being pressed to be separated from the communication hole 23.
Thus, under the condition that the gas generating agent 22 is not ignited, the elastic sealing element 30 can be sealed at the communication hole 23 to well isolate the first storage cavity 11 and the second storage cavity 21, when the gas generating agent 22 is ignited, a large amount of gas can be generated, and the large amount of gas can generate a certain pressure on the elastic sealing element 30, so that the elastic sealing element 30 is deformed to be separated from the communication hole 23, and further the gas can enter the first storage cavity 11 from the second storage cavity 21 to push the fire extinguishing agent 13 to be sprayed out from the spraying hole 12 for extinguishing fire. The non-pressure storage type fire extinguishing apparatus 100 of the present application is simple, low in cost, and effective in isolation by providing the elastic sealing member 30 to isolate the fire extinguishing agent 13 from the gas generating agent 22.
It should also be noted that a large amount of gas can generate a certain pressure on the elastic sealing member 30, and this pressure can also be a pressure generated by the gas accumulating in the second storage chamber 21, and then the pressure in the second storage chamber 21 is increased, so as to act on the elastic sealing member 30.
In the embodiment of the present application, the first housing 10 is opened with a fixing hole 14 for communicating the first storage cavity 11 with the outside of the first housing 10, and the second housing 20 is fixed at the fixing hole 14, and one end having the communication hole 23 extends into the first storage cavity 11 from the fixing hole 14.
As described above, the first storage chamber 11 is formed between the first housing 10 and the second housing 20, so that the structure of the non-pressure storage type fire extinguishing apparatus 100 can be made more compact, and the gas discharged from the communication hole 23 can be completely introduced into the first storage chamber 11, thereby improving the housing stability of the fire extinguishing apparatus 100 and the ejection stability of the fire extinguishing agent 13.
Further, the first casing 10 and the second casing 20 may be integrally formed, or the second casing 20 may be fixedly connected to the first casing 10 through a subsequent process, specifically, by bonding or welding, and the like, which is not limited herein.
In some embodiments, the communication hole 23 is offset from the spout 12. Thus, when the gas generating agent 22 is ignited and the elastic sealing member 30 is forced to separate from the communicating hole 23, if the position of the nozzle hole 12 and the communicating hole 23 are aligned, the elastic sealing member 30 may block the nozzle hole 12, and therefore, the communicating hole 23 and the nozzle hole 12 are arranged to be misaligned, and the fire extinguishing agent 13 can be reliably sprayed.
In order to reliably seal the elastic sealing member 30 at the communication hole 23 when the gas generating agent 22 is not ignited, in some embodiments, the elastic sealing member 30 includes a main body 31 and elastic flanges 32 located at two sides of the main body 31 in the axial direction of the main body 31, the elastic flanges 32 are annular, an inner ring of the elastic flanges 32 is connected to the main body 31, an outer ring of the elastic flanges 32 is protruded from the main body 31 in the radial direction of the main body 31, one of the elastic flanges 32 elastically abuts against one side of the communication hole 23 in the axial direction thereof, the main body 31 is disposed through the communication hole 23, and the other elastic flange 32 elastically abuts against the other side of the communication hole 23 in the axial direction thereof.
In this way, an elastic clamping space is formed between the two elastic flanges 32 and the main body 31 to cooperate with the outer side of the communication hole 23 to seal the communication hole 23, and at the same time, the elastic sealing member 30 is limited by the second housing 20 at both sides, so that the elastic sealing member is not easy to separate from the communication hole 23 to cause sealing failure under the condition of self-gravity or other transportation bumps.
Specifically, the axial distance between the two elastic flanges 32 along the main body 31 is smaller than the axial dimension of the communication hole 23, so that when the elastic sealing member 30 is sealed at the communication hole 23, the two elastic flanges 32 are axially deformed to elastically abut against both sides of the communication hole 23 in the axial direction thereof.
Further, the main body 31 is elastically sealed in the communication hole 23 in the radial direction of the communication hole 23. Specifically, the radial dimension of the main body 31 is larger than that of the communication hole 23, so that, when the main body 31 is pierced through the communication hole 23, the main body 31 is radially deformed to seal the communication hole 23, thereby improving the sealing reliability of the elastic seal member 30.
In the embodiment of the present application, the elastic sealing member 30 is a rubber elastic sealing member or a silicone elastic sealing member, and is not limited herein. Thus, the elastic sealing element 30 is made of simple material, easy to manufacture and low in cost.
To ensure that the resilient seal 30 can be pressed out of the communication hole 23 after the gas generant 22 is ignited, in some embodiments the gas generant 22 has an ignition end that can be ignited, the ignition end being disposed toward the resilient seal 30. Preferably, the pilot end may be disposed directly opposite the resilient seal 30. Therefore, the distance between the elastic sealing member 30 and the gas generating agent 22 is minimized, so that energy is gathered on the elastic sealing member 30 at the moment when the gas generating agent 22 is ignited, and the gas generating agent is pushed away quickly and stably, and on the other hand, the problem that the gas generating agent 22 blocks the elastic sealing member 30 due to the excessive thrust of the gas generating agent 22 against the elastic sealing member 30, so that the second storage cavity 21 is over-pressurized, and the second housing 20 explodes or gas is ejected from the other end of the second storage cavity 21 can be avoided.
Further, the non-pressure storage type fire extinguishing apparatus 100 further comprises an actuating member 40, the actuating member 40 is controlled to be actuated to ignite the gas generating agent 22, a placement space 24 is formed between the elastic sealing member 30 and the ignition end of the gas generating agent 22, and the actuating member 40 is arranged in the placement space 24. In this manner, the ignition end of the gas generant 22 can be reliably ignited by the provision of the initiator 40. Specifically, the actuator 40 includes a heat wire or firing head.
In some embodiments, the non-pressure storage type fire extinguishing apparatus 100 further comprises an assisting powder charge 50, the assisting powder charge 50 is disposed in the placing space 24 and connected to the actuating member 40, and the actuating member 40 can ignite the assisting powder charge 50 to ignite the gas generating agent 22. Thus, by providing the booster 50, the ability to ignite can be further enhanced to ensure that the gas generant 22 can be ignited. Specifically, the booster charge 50 may be a pyrotechnic charge.
In some embodiments, the non-pressure storage type fire extinguishing apparatus 100 further comprises a covering member 60, and the covering member 60 is disposed in the second storage chamber 21 for covering the gas generating agent 22. By coating the gas generant 22 with the coating 60, the gas generant 22 can be stably combusted to continuously generate gas, and the coating 60 has heat insulation, shock resistance and salt corrosion resistance effects, thereby improving the IP protection grade of the gas generant 22. Specifically, the covering member 60 includes a covering silicone rubber.
Compared with the prior art, the non-pressure storage type fire extinguishing apparatus 100 provided by the embodiment of the utility model has the following beneficial effects:
under the condition that the gas generating agent 22 is not ignited, the elastic sealing member 30 can be sealed at the communication hole 23 to well isolate the first storage cavity 11 from the second storage cavity 21, when the gas generating agent 22 is ignited, a large amount of gas can be generated, the large amount of gas can generate a certain pressure on the elastic sealing member 30, so that the elastic sealing member 30 is deformed to be separated from the communication hole 23, and further the gas can enter the first storage cavity 11 from the second storage cavity 21 to push the fire extinguishing agent 13 to be sprayed out from the spraying hole 12 for extinguishing fire. The non-pressure storage type fire extinguishing apparatus 100 of the present application is simple, low in cost, and effective in isolation by providing the elastic sealing member 30 to isolate the fire extinguishing agent 13 from the gas generating agent 22.
