Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1 and 2, fig. 1 is a schematic view showing a structure of a fire extinguishing container according to an embodiment of the present invention, and fig. 2 is a sectional view of the fire extinguishing container shown in fig. 1 taken along a-a. The fire extinguishing container provided by one embodiment of the invention comprises a shell 10, a pressure relief element and a flame-extinguishing and noise-reducing part 20. The housing 10 has a fire extinguishing agent chamber 11 and a coolant chamber 12, and the housing 10 is provided with a nozzle 13. The flame-extinguishing sound-deadening member 20 includes a body 21, and the body 21 is provided in the housing 10 so that a cavity for passing a fire extinguishing substance released by burning a fire extinguishing agent is formed in the housing 10.

In the case of using the fire extinguishing container, the fire extinguishing agent is placed in the fire extinguishing agent chamber 11 and the coolant is placed in the coolant chamber 12. The fire extinguishing agent in the housing 10 is ignited, and when the air pressure in the housing 10 reaches a certain value, the fire extinguishing substance released by the combustion of the fire extinguishing agent breaks through the pressure relief element and is sprayed from the nozzle 13 to the outside. Compare in traditional container of putting out a fire, because be equipped with flame extinction amortization part 20 in the casing 10, flame extinction amortization part 20's setting has increased the space of the inside cavity of container of putting out a fire, can increase the pressurized time of casing 10 inner space and the time that the material of putting out a fire began to spout like this to increase the contact time of the material of putting out a fire and coolant, make the material of putting out a fire fully contact with the coolant, reduce the temperature of spouting of the material of putting out a fire.

It should be noted that, by sealing the pressure relief element at the position of the nozzle 13, when the air pressure inside the casing 10 does not reach a preset value, the casing 10 is always in a sealed state, so that the contact time between the fire extinguishing substance and the coolant can be increased, the fire extinguishing substance is fully contacted with the coolant, and the spraying temperature of the fire extinguishing substance is reduced.

Specifically, the pressure relief element is a pressure relief diaphragm, and the pressure relief diaphragm is sealed at the position of the spout 13.

In one embodiment, referring to fig. 2 and 3, fig. 2 shows a cross-sectional view of the fire-extinguishing container shown in fig. 1 taken along a-a, and fig. 3 is a schematic structural view of a flame-extinguishing and sound-attenuating member of the fire-extinguishing container shown in fig. 1. The body 21 has a passage 211, the side of the body 21 is provided with a flame and sound absorbing hole 22, and a gap is formed between the body 21 and the housing 10. When the fire extinguishing container is used, a fire extinguishing agent is placed in the fire extinguishing agent chamber 11, and a coolant is placed in the coolant chamber 12. The fire extinguishing agent in the shell 10 is ignited, when the fire extinguishing agent is a powdery or small block-shaped agent, the fire extinguishing agent is burnt violently, a large amount of fire extinguishing substances can be generated in the moment of burning, a large amount of heat is generated at the same time, and huge sound is generated after the fire extinguishing agent is started. Through setting up flame sound-absorbing hole 22 at body 21, after the fire extinguishing generating agent was ignited, partial high-pressure gas in casing 10 passed through flame sound-absorbing hole 22 and got into in the clearance between casing 10 and body 21 for gas gets into a relatively great space, can slow down the expanding velocity of gas like this, reaches the effect of noise reduction.

Further, referring to fig. 2 and 3, the outer surfaces of the two ends of the body 21 are respectively provided with a first mounting portion 212 and a second mounting portion 213 in a protruding manner, so that a gap is formed between the side portion of the body 21 and the housing 10. Alternatively, the first mounting portion 212 is disposed around one end of the body 21, and the second mounting portion 213 is disposed around the other end of the body 21. When mounted, the first and second mounting portions 212 and 213 are respectively brought into contact with the inner surface of the housing 10 to mount the flame trap and noise reduction member 20 in the housing 10. Because a gap is formed between the side part of the body 21 and the shell 10, high-pressure gas generated after the fire extinguishing propellant burns can enter the gap from the flame-extinguishing sound-extinguishing hole 22, so that the high-pressure gas enters a relatively large space, the expansion speed of the gas can be reduced, and the effect of reducing noise is achieved.

In one embodiment, referring to fig. 2 and 3, the outer surfaces of the first mounting portion 212 and the second mounting portion 213 are provided with the sealing rings 50, so that the flame suppressing and noise reducing member 20 can be stably mounted in the housing 10 through the sealing rings 50, and the flame suppressing and noise reducing member 20 is prevented from moving in the housing 10 to affect the flame suppressing and noise reducing effects.

In one embodiment, referring to fig. 2 and 3, the plurality of flame extinguishing holes 22 are provided, and the plurality of flame extinguishing holes 22 are spaced around the side of the body 21. Through being equipped with a plurality of flame extinguishing sound holes 22 at the lateral part ring of body 21, the high-pressure gas that the burning of the generating agent that puts out a fire can be fast in getting into the clearance between casing 10 and the body 21 from flame extinguishing sound holes 22 for high-pressure gas gets into a relatively great space, can slow down gaseous expanding speed like this, reaches the effect of noise reduction.

Specifically, in the present embodiment, six flame suppression holes 22 are provided, and the six flame suppression holes 22 are disposed around the side portion of the body 21 at equal intervals. Of course, in other embodiments, four, five, seven, or more, etc. flame suppression holes 22 may be provided, and the number of flame suppression holes 22 is not particularly limited herein.

Further, referring to fig. 4, fig. 4 is a schematic structural view of another view of the flame-extinguishing and sound-attenuating member of the fire-extinguishing container shown in fig. 3. The peripheral wall of the flame-quenching hole 22 has a flow guide part 221, and the flow guide direction of the flow guide part 221 faces the outside of the body 21. It can be understood that the hole wall of the flame suppression hole 22 has a certain thickness, and the flow guide part 221 is located on the hole wall of the flame suppression hole 22; the flow guide part 221 is an inclined surface. Because the peripheral wall of the flame-extinguishing hole 22 is provided with the flow guiding part 221, the flow guiding part 221 can play a role in guiding flow, and the linear movement of the air flow in the shell 10 is realized, so that the air in the shell 10 can rapidly enter the gap between the shell 10 and the body 21 from the flame-extinguishing hole 22, and the noise reduction effect is improved.

Specifically, the cross section of the flame-quenching hole 22 is trapezoidal, so that the high-pressure gas in the housing 10 can rapidly enter a relatively large space from the flame-quenching hole 22, and the noise reduction effect is good. Of course, in other embodiments, the cross-section of the flame suppression hole 22 may also be circular, elliptical, etc.

In one embodiment, referring to fig. 2 and 3, the coolant chamber 12 is disposed adjacent to the nozzle 13, and the flame suppressing member 20 is disposed between the fire extinguishing agent chamber 11 and the coolant chamber 12. It can be understood that the fire extinguishing agent in the housing 10 is ignited, and a large amount of gas is generated at the moment of combustion of the fire extinguishing agent; the gas rapidly enters a relatively large space from the position of the flame-extinguishing hole 22 to slow down the expansion speed of the gas, so as to achieve the effect of reducing the noise. Meanwhile, the fire extinguishing substance after burning the fire extinguishing generating agent enters the coolant chamber 12 from the passage 211 of the flame-extinguishing and noise-reducing member 20, the coolant in the coolant chamber 12 cools the fire extinguishing substance, and the cooled fire extinguishing substance is sprayed out from the spray ports 13, thereby reducing the spray temperature of the fire extinguishing substance.

In another embodiment, the coolant chamber 12 is disposed adjacent to the nozzle hole 13, and the flame trap silencing member 20 is disposed on a side of the coolant chamber 12 adjacent to the nozzle hole 13. Alternatively, the flame suppressing and sound attenuating member 20 is provided at the position of the spout 13. It can be understood that the fire extinguishing agent in the housing 10 is ignited, and the fire extinguishing substance and gas generated by the combustion of the fire extinguishing agent enter the cooling chamber, and the cooling agent in the cooling chamber cools the fire extinguishing substance. The cooled fire extinguishing substance is sprayed out from the nozzle 13 through the channel 211 of the flame-extinguishing and sound-deadening member 20, and the gas generated by the combustion of the fire extinguishing agent enters a relatively large space through the flame-extinguishing and sound-deadening holes 22, so that the expansion speed of the gas is slowed down, and the effect of reducing noise is achieved.

In one embodiment, referring to fig. 2 and 3, the flame-extinguishing and sound-deadening member 20 further includes a first screen 23, and the first screen 23 is disposed in the channel 211 of the body 21. Alternatively, the first screen 23 is provided at the end of the channel 211 remote from the extinguishing agent chamber 11. It should be noted that the grid density of the first screen 23 may be set according to actual requirements. Through inside or the tip at passageway 211 sets up first net 23 that separates, first net 23 that separates can play the effect of putting out a fire, reduces the phenomenon that the in-process that extinguishing device put out a fire and appears spouting fire. When the flame-extinguishing and noise-reducing member 20 is disposed between the fire extinguishing agent chamber 11 and the coolant chamber 12, the first partition net 23 partitions the internal space of the housing 10 into the fire extinguishing agent chamber 11 and the coolant chamber 12, thereby preventing the coolant from entering the fire extinguishing agent chamber 11 and affecting the fire extinguishing effect.

Please refer to fig. 2 and 3, if the first separation net 23 is disposed in the channel 211 of the body 21, the first separation net 23 separates the channel 211 of the body 21 into two spaces. The flame-extinguishing sound-deadening hole 22 is provided in the side portion of the body 21 close to the fire extinguishing agent chamber 11, and the coolant is placed in the space of the body 21 away from the fire extinguishing agent chamber 11.

In one embodiment, referring to fig. 2, the flame arresting and noise reducing device further comprises a second screen 30, and the second screen 30 is disposed between the fire extinguishing agent chamber 11 and the coolant chamber 12. It should be noted that the grid density of the second screen 30 can be set according to actual requirements. The second separation net 30 is arranged between the fire extinguishing agent chamber 11 and the coolant chamber 12, on one hand, the second separation net 30 can compress the fire extinguishing generating agent, and the noise generated by the shaking of the fire extinguishing generating agent in the using process is avoided; on the other hand, because the fire extinguishing agent reacts violently in the combustion process, the second screen 30 can block the fragments generated by the fire extinguishing agent in the combustion process, so as to prevent the fragments and the like from blocking the flame-extinguishing holes 22, and ensure the flame-extinguishing and noise-reducing effects.

In one embodiment, referring to FIG. 2, the fire suppression container further includes a third screen 40, the third screen 40 being disposed on top of the coolant chamber 12. It will be appreciated that if the flame suppressing and sound attenuating member 20 is provided between the fire extinguishing agent chamber 11 and the coolant chamber 12, the third screen 40 is correspondingly provided in the coolant chamber 12 near the nozzle 13. If the flame-suppressing noise reducing member 20 is provided at the position of the nozzle hole 13, the third screen 40 is provided between the coolant chamber 12 and the flame-suppressing noise reducing member 20. Generally, the coolant is one or more of granular, plate-like, or block-like coolant, which is loosely placed in the coolant chamber 12, and the coolant may be shaken during use, thereby generating noise. In this embodiment, the third screen 40 is disposed on the top of the coolant chamber 12, so that the third screen 40 can compress the coolant, and the coolant is prevented from shaking during use to generate noise.

In another embodiment, in conjunction with FIG. 5, FIG. 5 is a cross-sectional view of a fire suppression container of another embodiment of the present invention. The flame trap and noise reduction member 20 may be an elastic member 24. A mesh plate 25 is movably provided in the housing 10, and the mesh plate 25 is provided between the fire extinguishing agent chamber 11 and the coolant chamber 12. One end of the elastic member 24 is pressed against the fire extinguishing agent chamber 11, and the other end of the elastic member 24 is pressed against the screen plate 25. When the fire extinguishing container is used, a fire extinguishing agent is placed in the fire extinguishing agent chamber 11, and a screen plate 25 is placed in the coolant chamber 12; the spring 24 is under compression under the weight of the coolant. The fire extinguishing agent is ignited, the fire extinguishing substance released by the fire extinguishing agent is burnt and enters the coolant chamber 12, and the coolant in the coolant chamber 12 cools the fire extinguishing substance, so that part of the coolant is consumed, and the coolant is gradually reduced. During the consumption of the coolant, the elastic member 24 is gradually extended and the space of the cavity in the housing 10 is increased. Therefore, the pressurizing time of the inner space of the shell 10 and the time for starting spraying the fire extinguishing substances can be increased, so that the contact time of the fire extinguishing substances and the coolant is increased, the fire extinguishing substances are fully contacted with the coolant, and the spraying temperature of the fire extinguishing substances is reduced. And after the fire extinguishing generating agent is ignited, part of high-pressure gas enters a relatively large space, so that the expansion speed of the gas can be reduced, and the effect of reducing noise is achieved.

Referring to fig. 6, fig. 6 is a sectional view of a fire extinguishing container according to another embodiment of the present invention. Of course, in other embodiments, the resilient member 24 may be provided on the side of the coolant chamber 12 adjacent the nozzle 13. Specifically, the mesh plate 25 is movably provided on the top of the coolant chamber 12; one end of the elastic member 24 is pressed against the mesh plate 25, and the other end of the elastic member 24 is pressed against the inner surface of the housing 10. During the consumption of the coolant, the elastic member 24 is gradually extended and the space of the cavity in the housing 10 is increased. Therefore, the pressurizing time of the inner space of the shell 10 and the time for starting spraying the fire extinguishing substances can be increased, so that the contact time of the fire extinguishing substances and the coolant is increased, the fire extinguishing substances are fully contacted with the coolant, and the spraying temperature of the fire extinguishing substances is reduced. And after the fire extinguishing generating agent is ignited, part of high-pressure gas enters a relatively large space, so that the expansion speed of the gas can be reduced, and the effect of silencing is achieved. In addition, the screen plate 25 is arranged above the coolant chamber 12, so that the screen plate 25 can compress the coolant, and the coolant is prevented from shaking to generate noise in the use process.

In one embodiment, referring to fig. 2, the housing 10 includes a first housing 14 and a second housing 15, and the first housing 14 is screwed to the second housing 15. The spout 13 is provided on the top of the second housing 15. Specifically, the open end of the first casing 14 is provided with an external thread, the end of the second casing 15 far away from the nozzle 13 is provided with an internal thread, and the first casing 14 and the second casing 15 are detachably connected through threads. In particular, in the present embodiment, the first housing 14 is a cylindrical structure.

In one embodiment, referring to fig. 2, the housing 10 has an outlet 16. It will be understood that since the housing 10 is provided with the outlet hole 16, the heat sensitive wire or the ignition head can be accessed to the inside of the fire extinguishing agent chamber 11 through the outlet hole 16, and the heat sensitive wire or the ignition head is brought into contact with the fire extinguishing agent. When a fire occurs, the flame ignites the electric ignition head or the heat-sensitive wire, so that the fire extinguishing device is started to realize the purpose of extinguishing fire.

Specifically, referring to fig. 2, the coolant chamber 12 is disposed close to the first housing 14, and the fire extinguishing agent chamber 11 is disposed away from the first housing 14. The outlet hole 16 is correspondingly arranged at the bottom of the first shell 14, so that the heat-sensitive wire or the ignition head can be conveniently accessed into the fire extinguishing agent chamber 11, and the cost is saved.

The fire extinguishing apparatus of an embodiment, please refer to fig. 1 and 5, includes a fire extinguishing generating agent, a coolant, an actuating component and a fire extinguishing container of any of the above embodiments. The fire extinguishing agent is provided in the fire extinguishing agent chamber 11, and the coolant is provided in the coolant chamber 12. The starting component is used for igniting the fire extinguishing agent.

When the fire extinguishing container is used, the fire extinguishing agent in the shell 10 is ignited, and when the air pressure in the shell 10 reaches a certain value, the fire extinguishing substance released by the fire extinguishing agent is combusted to break through the pressure relief element and is sprayed to the outside from the nozzle 13. Compare in traditional container of putting out a fire, because be equipped with flame extinction amortization part 20 in the casing 10, flame extinction amortization part 20's setting has increased the space of the inside cavity of container of putting out a fire, can increase the pressurized time of casing 10 inner space and the time that the material of putting out a fire began to spout like this to increase the contact time of the material of putting out a fire and coolant, make the material of putting out a fire fully contact with the coolant, reduce the temperature of spouting of the material of putting out a fire.

In one embodiment, the fire extinguishing agent can be an aerosol fire extinguishing agent, or a mixture of the aerosol fire extinguishing agent and other fire extinguishing agents. The aerosol fire extinguishing agent has the characteristics of no pollution, no damage, easy cleaning and the like, and is widely applied to various fire extinguishing places. When a fire occurs, the flame ignites the starting member, thereby igniting the aerosol fire extinguishing agent, which itself rapidly undergoes an oxidation-reduction reaction and is rapidly combusted by oxygen provided in the housing 10. The combusted aerosol fire extinguishing agent passes through the coolant chamber 12, and the coolant in the coolant chamber 12 absorbs its heat to form an aggregated aerosol fire extinguishing substance, which is sprayed from the nozzle 13 to the outside.

Further, the aerosol fire extinguishing agent is in one or more of powder, granule, tablet or block. It should be understood that when the aerosol fire extinguishing agent is in the form of powder, granule, tablet or block, the specific surface area per unit mass of the aerosol fire extinguishing agent is increased or the density per unit volume is decreased, so that once the aerosol fire extinguishing agent is ignited, the combustion will quickly diffuse, and a large amount of fire extinguishing substances are instantaneously released in a deflagration manner, thereby increasing the spraying speed and achieving a better fire extinguishing effect.

In one embodiment, the above-mentioned starting member may be an electric igniter, or the starting member may be a heat-sensitive wire. When a fire occurs, the flame ignites the electric ignition head or the heat-sensitive wire, so that the fire extinguishing device is started to realize the purpose of extinguishing fire.
