Referring to fig. 1, fig. 1 shows a schematic cross-sectional structure of a fire extinguishing apparatus according to an embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.
Referring to the drawings, an embodiment of the present invention provides a fire extinguishing apparatus 100 including a fire extinguishing container 10, a fire spraying assembly 20, and a plurality of capsules 30.
The fire extinguishing container 10 is provided with a containing cavity 11, one end of the fire extinguishing container is provided with a nozzle opening 12 communicated with the containing cavity 11, the spraying assembly 20 comprises an ignition piece 21 and an aerosol fire extinguishing agent 22, the aerosol fire extinguishing agent 22 is filled in the containing cavity 11, and the ignition piece 21 is used for igniting the aerosol fire extinguishing agent 22 to generate fire extinguishing substances, so that the fire extinguishing substances are sprayed out of the nozzle opening 12 along a spraying path.
A plurality of capsules 30 are located in the receiving chamber 11 and on the dispensing path, the capsules 30 are filled with liquid perfluorohexanone, and the capsules 30 are configured to rupture upon heating to release the liquid perfluorohexanone.
In some embodiments, capsule 30 is made of plastic or resin, both of which are fast and easily melted materials, so that capsule 30 can be ruptured immediately after being heated to release liquid perfluorohexanone, thereby improving fire extinguishing efficiency.
In this manner, when the aerosol fire extinguishing agent 22 is ignited by the ignition element 21, the aerosol fire extinguishing agent 22 generates high-temperature fire extinguishing substances having a certain initial velocity of the fire and being ejected toward the ejection port 12 along the path of the fire, and during the ejection toward the ejection port 12, the plurality of capsules 30 are ruptured by the high-temperature fire extinguishing substances to release the liquid perfluorohexanone, and the liquid perfluorohexanone can absorb the heat of the fire extinguishing substances to be vaporized, and therefore, the corresponding high-temperature fire extinguishing substances release the heat to be cooled down to reduce the temperature of the fire extinguishing substances ejected from the ejection port 12. In addition, the boiling point of the perfluorohexanone is 49.2 ℃, so the perfluorohexanone has a very low boiling point and can be quickly vaporized after being heated, the vaporized perfluorohexanone in a gas state also has a fire extinguishing effect and participates in fire extinguishing together with fire extinguishing substances, and if the aerosol fire extinguishing agent 22 is insufficiently combusted, residues are likely to be sprayed outwards under the pushing of the fire extinguishing substances, but in the process of contacting the liquid perfluorohexanone, the temperature of the residues is reduced, condensed and deposited or attached to the inner wall of the accommodating cavity 11, so the cleanliness of the sprayed fire extinguishing substances is further improved, and the fire extinguishing device 100 has the capability of extinguishing E-type fire (electric appliance fire). The utility model discloses a fire extinguishing device 100, the temperature that has improved fire extinguishing efficiency and spun fire extinguishing substance is low.
In embodiments of the present invention, the aerosol fire suppressant 22 is in the form of one or any combination of powders, granules, tablets, or blocks.
Referring again to fig. 1, in some embodiments, the fire extinguishing container 10 is cylindrical, and in other embodiments, the fire extinguishing container 10 may have other shapes, such as a conical shape, a rectangular shape, etc., without limitation.
In some embodiments, the fire extinguishing container 10 includes a cylindrical container body and a front cover detachably mounted to one end of the cylindrical container body, wherein the front cover is provided with a spout 12. The provision of the front cover facilitates the placement of the aerosol fire suppressant 22 and the plurality of capsules 30 within the receiving cavity 11.
In some embodiments, the aerosol fire suppressant 22 is located at an end of the receiving chamber 11 remote from the spout 12. Specifically, the aerosol fire extinguishing agent 22 and the nozzle 12 can be arranged oppositely, so that after the aerosol fire extinguishing agent 22 is ignited, the aerosol fire extinguishing agent is directly sprayed to the nozzle 12 along the axial direction of the accommodating cavity 11, the spraying speed is prevented from being influenced by the tortuous spraying path, the contact length of the high-temperature fire extinguishing substance and the liquid perfluorohexanone in the spraying path can be increased, and therefore the liquid perfluorohexanone is fully utilized, and the temperature of the fire extinguishing substance is further reduced.
Further, the fire extinguishing container 10 has a bottom wall 13 and a side wall 14 which is arranged along the circumference of the bottom wall 13 and connected with the bottom wall 13, the bottom wall 13 and the side wall 14 are enclosed to form an accommodating cavity 11, the bottom wall 13 and the side wall 14 define a positioning space, and the positioning space is attached to the outer side of the aerosol fire extinguishing agent 22 to position the aerosol fire extinguishing agent 22.
In order to improve the combustion efficiency of the aerosol fire extinguishing agent 22, the bottom wall 13 and the side wall 14 are used for defining a positioning space for positioning the aerosol fire extinguishing agent 22, and the aerosol fire extinguishing agent 22 can be guided to be combusted layer by layer only from one side facing the nozzle hole 12 to the bottom wall 13 at the side far away from the nozzle hole 12 after being ignited by the ignition element 21, so that the multi-directional combustion of the aerosol fire extinguishing agent 22 is avoided, and the aerosol fire extinguishing agent 22 is not combusted fully or is remained too much. In addition, the positioning space can also prevent the fire extinguishing device 100 from being failed due to damage and fragmentation of the aerosol fire extinguishing agent 22 or separation of the ignition element 21 from the aerosol fire extinguishing agent 22 caused by the force of transportation sloshing or external impact before the fire extinguishing device 100 is used.
In other embodiments, the fire extinguishing apparatus 100 further includes a positioning member 40, the positioning member 40 is located in the accommodating chamber 11, the positioning member 40 has an accommodating chamber 41 and a communication hole 42, the accommodating chamber 41 is communicated with the accommodating chamber 11 through the communication hole 42, and the aerosol fire extinguishing agent 22 is filled in the accommodating chamber 41 and attached to an inner wall of the accommodating chamber 41 to be positioned in the accommodating chamber 41. In this way, after the aerosol fire extinguishing agent 22 is ignited, the aerosol fire extinguishing agent 22 is confined by the positioning member 40 and is sufficiently combusted in the positioning member 40.
Further, the positioning element 40 is an elastic positioning element, and an outer wall of the elastic positioning element abuts against an inner wall of the accommodating cavity 11, so that the elastic positioning element is positioned in the accommodating cavity 11. Specifically, the bottom of the outer side of the elastic positioning element abuts against the bottom wall 13 of the accommodating cavity 11, and the elastic positioning element abuts against the side wall 14 of the accommodating cavity 11 along the circumferential direction, so that the elastic positioning element is positioned in the accommodating cavity 11. The use of the elastic positioning member not only improves the combustion efficiency of the aerosol fire extinguishing agent 22, but also buffers the impact force when the fire extinguishing apparatus 100 is impacted by external impact, so as to prevent the aerosol fire extinguishing agent 22 from being damaged and broken or the ignition member 21 from being separated from the aerosol fire extinguishing agent 40.
Specifically, the elastic positioning element is made of silicone, and in other embodiments, the elastic positioning element may also be made of elastic material such as rubber, which is not limited herein.
In some embodiments, the fire suppression apparatus further comprises a mesh separator 45, the mesh separator 45 being fixed in the receiving cavity and disposed in the burst path, the mesh separator 45 separating the aerosol fire suppressant 22 and the plurality of capsules 30. The mesh-like partition 45 prevents the capsule 30 from falling into the space where the aerosol fire extinguishing agent 22 is present after the capsule 30 is ruptured, thereby preventing the capsule 30 from affecting the combustion of the aerosol fire extinguishing agent 22. Specifically, the mesh-like spacer 45 is circumferentially fitted to the inner wall of the accommodating chamber 11.
In some embodiments, the ignition member 21 includes an ignition end 211 and a connection end 212, the ignition end 211 being located outside the fire-extinguishing container 10, the connection end 212 being in contact with the aerosol fire-extinguishing agent 22, wherein the connection end 212 is located on a side of the aerosol fire-extinguishing agent 22 facing the spout 12. In this way, after the ignition member 21 is ignited, the aerosol fire extinguishing agent 22 generates a fire extinguishing substance, and since the ignition end 211 of the ignition member 21 is located on the side of the aerosol fire extinguishing agent 22 toward the nozzle hole 12, that is, the spray path between the aerosol fire extinguishing agent 22 initially ignited by the ignition member 21 and the nozzle hole 12 is shortest, the fire extinguishing substance can be rapidly sprayed toward the nozzle hole 12, and the fire extinguishing speed is increased.
In some embodiments, the ignition member 21 is a heat-sensitive wire. The ignition of the aerosol fire suppressant 22 may be facilitated by igniting the heat sensitive wire, thereby igniting the aerosol fire suppressant 22.
In another embodiment, the pilot 21 may also be an electrical initiator.

More specifically, the controller may be an industrial personal computer, a PLC controller, an MCU controller, or the like. The detector may be a temperature sensitive detector. The temperature sensitive detector can detect the occurrence of fire by sensing temperature. The fire signal is a temperature abnormal signal. When the temperature detector senses that the temperature is abnormal, the temperature abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 22.
In other embodiments, as shown in FIG. 2, the electrical initiator may also include an activation button 213, a piezo-ceramic 214, and a high voltage lead 215, and the piezo-ceramic 214 is pressurized by pressing the activation button 213 to generate a voltage within the high voltage lead 215 to ignite the aerosol fire suppressant 22. Further, the fire extinguishing container 100 further comprises a safety pin 50 and a safety tab 60, the safety tab 60 being connected to the safety pin 60, the safety pin 50 comprising a locking position and an unlocking position, the safety pin 50 abutting the activation button 213 to restrict the activation button 213 from moving towards the piezo ceramic when the safety pin 50 is in the locking position, the safety tab 60 pulling the safety pin 60 out of engagement with the activation button 213 when the safety pin 50 is in the unlocking position. This approach may be applicable to portable fire suppression apparatus 100.
In other embodiments, the detector may also be a smoke detector. The smoke detector can detect the occurrence of fire by sensing the smoke concentration. The fire signal is a smoke concentration abnormal signal. When the temperature-sensitive detector senses that the smoke concentration is abnormal, a smoke concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 22. The detector may also be a combustible gas detector. The smoke detector can detect the occurrence of fire by sensing the concentration of combustible gas. The fire signal is a combustible gas concentration abnormal signal. When the temperature-sensing detector senses that the concentration of the combustible gas is abnormal, a combustible gas concentration abnormal signal is sent to the controller, and the controller controls the electric initiator to start, so that the electric initiator ignites the aerosol fire extinguishing agent 22.
