In addition, the heating element 211 is arranged in the groove 21, so that the occupied space of the heating element 211 can be saved, and the whole fire extinguishing device 100 is simple in structure and convenient to arrange.

In some embodiments of the present invention, referring to fig. 17 and 18, the groove 21 includes a groove bottom wall 213 and two groove side walls 214, the two groove side walls 214 are opposed to each other, the groove bottom wall 213 is connected between the two groove side walls 214, and the heat generating element 211 is in contact with both the groove bottom wall 213 and the two groove side walls 214. From this, all contact through making heating element 211 and recess diapire 213 and two recess lateral walls 214, increased heating element 211 and the area of contact of putting out a fire core 2, make heating element 211 and put out a fire core 2 and realize trilateral contact to make heating element 211's heat can effectively transmit for putting out a fire core 2, make the core 2 that puts out a fire can be lighted rapidly and to the indoor a large amount of fire extinguishing gas of release, realize putting out a fire fast.

Optionally, the heating time of the heating element 211 is t, where t satisfies: t is more than or equal to 1s and less than or equal to 30 s. Specifically, for example, when the time t < 1s, the heating time of the heating element 211 is too short, the temperature of the heating element 211 may not reach the ignition temperature of the fire extinguishing core 2, and thus the fire extinguishing core 2 may not be ignited, and the fire may not be rapidly extinguished at the initial stage of the fire; when the time t is greater than 30s, the ignition operation is already completed, and the heating element 211 is still heating, resulting in an unnecessarily long heating time. Wherein t is preferably 3 s.ltoreq.t.ltoreq.8 s. Thus, the heating time t of the heating element 211 satisfies: t is more than or equal to 1s and less than or equal to 30s, so that the fire extinguishing core 2 can be ignited at the initial stage of fire, and rapid fire extinguishing is realized.

Optionally, the ignition temperature of the fire extinguishing core 2 is T, where T satisfies: t is more than or equal to 200 ℃ and less than or equal to 1000 ℃. Therefore, when T is more than or equal to 200 ℃ and less than or equal to 1000 ℃, the fire extinguishing core 2 can be rapidly ignited at the initial stage of fire, so that the fire extinguishing gas released by the fire extinguishing core 2 can be filled indoors, the indoor open fire can be effectively extinguished, the fire extinguishing accuracy can be ensured, and the fire extinguishing core 2 can be prevented from being ignited by mistake. Further optionally, T further satisfies: t is more than or equal to 400 ℃ and less than or equal to 550 ℃.

Alternatively, the fire extinguishing core 2 can burn normally under 95% humidity.

In some embodiments of the present invention, as shown in fig. 17 and 19, the heating element 211 is a heating wire winding that extends spirally in the axial direction. With the arrangement, the heat generating element 211 has high condensation heat capacity, and can form a thermal vortex, so that the fire extinguishing core 2 can be rapidly ignited to extinguish fire.

In some embodiments of the present invention, referring to fig. 9, 10 and 17, a first accommodating chamber 11 and a second accommodating chamber 12 isolated from each other are defined in the housing 1, the fire extinguishing core 2 is disposed in the first accommodating chamber 11, a circuit board 121 and a power supply battery 122 are disposed in the second accommodating chamber 12, the power supply battery 122 is electrically connected to the circuit board 121, and both ends of the heating element 211 are electrically connected to the circuit board 121 through ignition wires 212, respectively. For example, in the example of fig. 9, 10 and 17, the first accommodation chamber 11 and the second accommodation chamber 12 are isolated from each other, and the wiring board 121 and the power supply battery 122 are provided in the second accommodation chamber 12. The power supply battery 122 is used to supply power to the circuit board 121. The first accommodating cavity 11 is internally provided with a fire extinguishing core 2. Both ends of the heating element 211 are respectively connected with ignition wires 212, and the ignition wires 212 are electrically connected with the circuit board 121. For example, when the fire extinguishing core 2 in the first accommodating chamber 11 is burned, the temperature in the first accommodating chamber 11 may rapidly rise, for example, to reach a high temperature of 1000 ℃, but since the first accommodating chamber 11 and the second accommodating chamber 12 are physically separated from each other, the high temperature in the first accommodating chamber 11 does not affect the normal operation of the circuit board 121 or the power supply battery 122. Optionally, a thermal insulation pad, for example, an alumina silicate ceramic fiber thermal insulation pad, may be disposed between the first receiving chamber 11 and the second receiving chamber 12 to further reduce heat transfer. Therefore, the first accommodating cavity 11 and the second accommodating cavity 12 which are separated from each other are defined in the shell 1, and the damage of high temperature to the circuit board 121 and the power supply battery 122 in the second accommodating cavity 12 can be effectively avoided. Wherein, the housing 1 can be a metal housing to realize rapid heat dissipation.

In some optional embodiments of the present invention, referring to fig. 27, the circuit board 121 is switchable between a sleep mode and an operating mode, the circuit board 121 defaults to the operating mode when powered on for the first time, and when the circuit board 121 does not receive a start command within a preset time, the circuit board 121 is switched from the operating mode to the sleep mode. For example, when the circuit board 121 is first powered on, the circuit board 121 defaults to an operational mode, where the circuit board 121 is in an awake state. When the start command is not received within the preset time, the circuit board 121 will automatically enter the sleep mode. It should be noted that, when the circuit board 121 is in the sleep mode, the electrical components are turned off, only one control unit has power supply or monitoring with low power, and when the circuit board 121 receives a start command, other electrical units can be awakened through the control unit. Therefore, by the above arrangement, the power consumption of the circuit board 121 can be reduced, and the service life of the power supply battery 122 can be prolonged.

In some embodiments of the present invention, referring to fig. 27, the housing 1 is provided with a network interface 17, the network interface 17 is in communication connection with a circuit board 121, and when an abnormality occurs in the circuit board 121 or the voltage of the power supply battery 122 is lower than a predetermined voltage, a remote console in communication connection with the network interface 17 outputs an alarm signal. Wherein, extinguishing device 100 can be through wiring to remote control platform, and remote control platform can be equipped with awaken button and self-checking button. When the ignition program is detected, the wake-up button and the self-checking button can be clicked in sequence, the circuit board 121 is switched to a working mode, when the ignition program is detected to be normal during remote access monitoring, a state signal is returned to the remote control console, and if the ignition program is detected to be abnormal, a warning signal is returned to prompt maintenance.

For example, the fire extinguishing core 2 may include a plurality of first fire extinguishing cores (as shown in fig. 17, 18 and 26) each having a groove 21 formed thereon, and a plurality of second fire extinguishing cores (not shown) adapted to control the plurality of heating elements 211 on the plurality of first fire extinguishing cores to be energized in sequence. For example, when there are three first fire extinguishing cores, the circuit board 121 controls the three heating elements 211 on the three first fire extinguishing cores to be sequentially energized. The three heating elements 211 correspond to three channels on the circuit board 121, and may be, for example, 1 channel, 2 channels, and 3 channels. The network interface 17 is in communication connection with the circuit board 121, the fire extinguishing apparatus 100 can be accessed from the outside through limited network authority, and the remote command executes the simulated ignition program test function to check whether the circuit board 121 works normally. Specifically, when the ignition program is detected, the ignition program on the circuit board 121 is operated in a simulated manner once, that is, after the 1-channel is powered on for several seconds, the 2-channel is powered on for the same number of seconds, and finally the 3-channel is powered on for the same number of seconds, and the heating element 211 is not really powered on for ignition at this time. Through the above process, the health feedback function of the circuit board 121 can be realized.

The power supply battery 122 is located in the second accommodating cavity 12, and when the circuit board 121 is in the sleep mode, almost all that is consumed is self-discharge of the power supply battery 122 itself, and a stable self-consumption curve is provided. However, the long-term power consumption also has a critical value, and when the voltage value is lower than the ignition requirement, the power supply battery 122 needs to be replaced. When the circuit board 121 is designed, the ignition line 212 can be remotely wired, the voltage of the power supply battery 122 can be accessed in real time on a remote control console, the voltage can be displayed on a cloud system, when the voltage is reduced to reach an alarm value, the system can give a low-voltage alarm, and a background manager can conveniently inform a specially-assigned person to go to the fire extinguishing device 100 to replace the power supply battery 122.

Therefore, through the arrangement, the health feedback of the circuit board 121 and the voltage feedback of the power supply battery 122 can be realized, the normal operation of the fire extinguishing device 100 can be ensured, and effective fire extinguishing is realized.

Alternatively, the heating element 211 may be a nickel-chromium alloy resistance wire or the like. From this, when heating element 211 is the nichrome resistance wire, the intensity of nichrome resistance wire in high temperature environment is high, long-term high temperature operation non-deformable, difficult change structure, and the normal atmospheric temperature plasticity of nichrome resistance wire is good, and the restoration after the deformation is comparatively simple. Moreover, the nickel-chromium alloy resistance wire has high radiance, no magnetism, good corrosion resistance and long service life. Of course, the heating element 211 may be made of other materials that can generate heat by being energized, and is not limited to the nichrome resistance wire.

Alternatively, the fire extinguishing apparatus 100 may be applied to an indoor space in which organisms exist. It should be noted that "indoor space" refers to the interior of a building, that is, the interior space of a building, such as a residential building, an apartment building, an office building, a shopping mall, a restaurant kitchen, a large, medium, small warehouse, or a room of a hotel or a corridor. Of course, the fire suppression apparatus 100 may also be used in enclosed spaces, such as mines, oil storage tanks, sand wells, tunnels, pump rooms or computer rooms.

In some embodiments of the present invention, referring to fig. 9, 10 and 26, at least one first through hole 111 is formed on the housing 1, the fire extinguishing core 2 is disposed in the housing 1, the fire extinguishing core 2 is solid, and the fire extinguishing core 2 generates non-toxic fire extinguishing gas when burning and is suitable for being sprayed to the outside of the housing 1 through the first through hole 111. For example, the fire extinguishing wick 2 may be an aerosol-based condensation fire extinguishing agent which is a special mixture of combustible components/constituents, mainly composed of three substances of potassium nitrate, dicyandiamide and organic resin, exists in a solid state after being manufactured, has no compressed gas, is physically stable, and can be stored at-60 ℃ to-160 ℃. Once heated to a certain temperature range at high temperature, the fire extinguishing core 2 can be violently combusted and release a large amount of fire extinguishing gas (the fire extinguishing gas is safe, non-toxic and harmless through a toxicity test report) to fill (completely cover or completely submerge) the whole indoor space, potassium ions generated by combustion of the fire extinguishing core 2 enter a flame chain to take away oxygen ions, hydrogen ions and hydroxyl ions, so that the flame chain is broken, the fire cannot be continuously combusted, but oxygen in the air is not consumed, and the fire extinguishing effect is realized. Wherein, casing 1 is not pressure vessel, and extinguishing device 100 is non-pressurized gas device, and after extinguishing device 100 igniteed, the fire extinguishing core 2 that burns the non-pressure solid fire extinguishing core becomes pressurized fire extinguishing gas and releases, reaches the effect that needs pressure vessel to spray out, and extinguishing device 100 can be non-maintaining, need not to monitor atmospheric pressure, and need not external power source. Thus, the fire extinguishing core 2 is burned to generate a non-toxic fire extinguishing gas, so that the entire fire extinguishing apparatus 100 has fire extinguishing safety and is suitable for an indoor space in which a living body (e.g., a person) is present. Moreover, because the fire extinguishing core 2 is solid, the fire extinguishing core is not required to be pushed by compressed gas, no pressure exists in the shell 1, and regular maintenance is not required. In addition, since the fire extinguishing core 2 itself contains an oxidizing agent, it is possible to eliminate the need to consume oxygen in the indoor space.

In some embodiments of the present invention, referring to fig. 10, 17 and 26, the fire suppression apparatus 100 further includes at least two alarm devices (not shown) disposed adjacent to the housing 1. The shell 1 is internally provided with a circuit board 121, the fire extinguishing core 2 is provided with a heating element 211, the circuit board 121 is electrically connected with the heating element 211, and when at least two alarms give an alarm, the circuit board 121 controls the heating element 211 to be electrified. For example, when two alarms are arranged on the housing 1, if the two alarms alarm at the same time, the two alarms are regarded as fire alarms, and a starting command is directly sent to the circuit board 121 through a network dedicated connection line, so that the intelligent automatic starting is realized, and the unattended function is realized; when only an alarm was reported to the police, the propelling movement function can be started to high in the clouds APP, through operator's 4G or 5G signal, on system administrator's cell-phone was pushed to the surveillance video in incident region, two option button of "putting out a fire" and "cancellation" were provided simultaneously, were decided to operate by the administrator. From this, through above-mentioned setting, realized extinguishing device 100's intelligence and independently started, and can improve the accuracy and the reliability of putting out a fire. Wherein, each alarm can be a smoke alarm, a temperature-sensing fire detector or an infrared sensing alarm and the like.

In some embodiments of the present invention, as shown in fig. 5, a circuit board 121 is disposed in the housing 1, a network interface 17 is disposed on the housing 1, the network interface 17 is communicatively connected to the circuit board 121, and the network interface 17 is connected to the remote controller through a network connection. For example, the circuit board 121 may be provided with a jumper pin, which may be wired to a start button (not shown) of the outdoor dedicated control box via a network connection. Wherein, the jumper wire pin is the same with on-the-spot manual start function, when pressing the start button on the outdoor control box, can realize long-range start. Thereby, a remote activation of the fire extinguishing device 100 may be achieved.

In some embodiments of the present invention, referring to fig. 10 and 23, a circuit board 121 is disposed in the housing 1, a trigger portion (not shown) is disposed on the circuit board 121, and the key 16 is disposed on the housing 1, and the key 16 is opposite to the trigger portion. For example, when a fire breaks out in a room, an operator can press the button 16 on the housing 1 to make the button 16 contact with the trigger part, and after the trigger part is triggered, the circuit board 121 controls the heating element 211 to be electrified, and the heating element 211 ignites the fire extinguishing core 2 after heating to extinguish the fire, so that the on-site manual start of the fire extinguishing device 100 can be realized by arranging the button 16 and the trigger part, and the fire extinguishing gas generated by burning the fire extinguishing core 2 can effectively extinguish the fire in the room.

In a further embodiment of the present invention, the fire extinguishing core 2 includes a plurality of first fire extinguishing cores (as shown in fig. 17, 18 and 26) each having a groove 21 formed thereon, and a plurality of second fire extinguishing cores (not shown) each having a plurality of heat generating elements 211 formed thereon into a plurality of heat generating element groups each including at least one heat generating element 211, the plurality of heat generating element groups being sequentially energized to generate heat. In the description of the present invention, "a plurality" means two or more. The grooves 21 are not provided on the plurality of second fire extinguishing cores, so that the second fire extinguishing cores have no heating elements 211 thereon. Wherein, the first core of putting out a fire is responsible for the ignition, and the second core of putting out a fire is close to next in its side, and when the first core of putting out a fire successfully ignites, its combustion temperature is about 1000 ℃, in the narrow and small space of first holding chamber 11, can all the second cores of putting out a fire of periphery all ignite, form "fire and burn and run together" effect, benefit from the space design in the shell, needn't make first core of putting out a fire to all cores 2 of putting out a fire, can reduce the quantity of heating element 211 group and the quantity of power supply battery 122 by a wide margin like this. For convenience of description, a group of heat generating element groups that are first energized will be referred to as a "first group of heat generating element groups". For example, when an indoor fire breaks out, the multiple groups of heating element groups can be sequentially queued for power-on heating under the control of the circuit board 121, the first fire extinguishing core where the heating element 211 in the first group of heating element group is located can be ignited after the first group of heating element group generates heat, and the ignited first fire extinguishing core can ignite the rest first fire extinguishing core and the rest second fire extinguishing core, so that the effect of 'fire burning and fire fighting' is achieved, thereby releasing fire extinguishing gas and realizing indoor fire extinguishing. The heat generating element groups that are energized after the first heat generating element group serve as redundant backups to achieve a supplemental firing when the first heat generating element group fails to fire. Therefore, by arranging the multiple groups of heating element groups, the multiple groups of heating element groups can ensure that the fire extinguishing core 2 can be ignited in time in the initial stage of fire, thereby releasing a large amount of fire extinguishing gas, realizing fire extinguishing and greatly improving the fire extinguishing reliability of the fire extinguishing device 100.

Alternatively, referring to fig. 26, the number of the first fire extinguishing cores may be three, and three heating elements 211 on the three first fire extinguishing cores are sequentially electrified to generate heat. Wherein, the three heating elements 211 on the three first fire extinguishing cores can be sequentially electrified and heated according to the program of '1 channel-2 channel-3 channel'. Thus, a "three-degree-of-redundancy" safeguard can be achieved, i.e. when one or two of the three heating elements 211 fail to ignite, the other heating element 211 can ensure successful ignition. Three first fire extinguishing cores are shown in fig. 26 for illustrative purposes, but it is obvious to those skilled in the art after reading the technical solution of the present application that the solution can be applied to other number of first fire extinguishing cores, which also falls within the protection scope of the present invention.

Alternatively, referring to fig. 1-9 and 16, the bottom of the housing 1 is provided with a mounting bracket 3. The mounting bracket 3 may be removably connected to the housing 1. Therefore, the installation of the fire extinguishing device 100 is facilitated by the installation of the installation bracket 3, so that the fire extinguishing device 100 can be suitable for various installation environments, such as a suspended ceiling, a wall or a desk.

In some embodiments of the present invention, as shown in fig. 1, 2, and 9-15, the fire suppression apparatus 100 includes a first housing 13, a second housing 14, and at least one fire extinguishing core 2. Specifically, a first cover 131 is disposed on the top of the first casing 13, a first accommodating cavity 11 is defined between the first casing 13 and the first cover 131, and a plurality of first through holes 111 are formed on the side wall of the first casing 13 at intervals. The second housing 14 is disposed in the first accommodating chamber 11, a side wall of the second housing 14 and a side wall of the first housing 13 are spaced apart from each other, a plurality of second through holes 1415 are formed on the side wall of the second housing 14, and the plurality of second through holes 1415 are staggered from the plurality of first through holes 111. The fire extinguishing core 2 is disposed in the second housing 14, and at least a portion of fire extinguishing gas generated by the combustion of the fire extinguishing core 2 is rebounded by the first cover 131 and then discharged through the second through hole 1415 and the first through hole 111 in sequence.

The second housing 14 is accommodated in the first accommodating chamber 11, the side wall of the second housing 14 and the side wall of the first housing 13 are arranged at intervals, a plurality of second through holes 1415 are formed on the side wall of the second housing 14, the plurality of second through holes 1415 are arranged at intervals, and the fire extinguishing core 2 is arranged in the second housing 14. When the fire extinguishing core 2 is ignited, fire extinguishing gas released by burning of the fire extinguishing core 2 is firstly sprayed out from the plurality of second through holes 1415, and due to the fact that the plurality of second through holes 1415 and the plurality of first through holes 111 are arranged in a staggered mode, the gas sprayed out from the second through holes 1415 flows to the plurality of first through holes 111 along the inner wall of the first shell 13, and is finally sprayed indoors from the plurality of first through holes 111, and rapid fire extinguishing is achieved. Thus, by providing the first and

second cases

Moreover, the plurality of second through holes 1415 are offset from the plurality of first through holes 111, so that the spraying path of the fire extinguishing gas can be extended, and the flame residue generated by the combustion of the fire extinguishing core 2 is prevented from being sprayed into the room along with the fire extinguishing gas, so that the flame residue can be retained in the first accommodating chamber 11.

In some alternative embodiments of the present invention, as shown in fig. 9 to 11 and 13, a plurality of first through holes 111 are formed in an upper portion of the first housing 13 to be spaced apart from each other in a circumferential direction, and a plurality of second through holes 1415 are formed in a lower portion of the second housing 14 to be spaced apart from each other in the circumferential direction. For example, in the example of fig. 9 to 11 and 13, the plurality of first through holes 111 are formed in the upper portion of the first housing 13, and the plurality of first through holes 111 are provided at regular intervals in the circumferential direction of the first housing 13. A plurality of second through holes 1415 are formed in a lower portion of the second housing 14, and the plurality of second through holes 1415 are uniformly spaced in a circumferential direction of the second housing 14. From this, through the aforesaid setting, the gaseous first through-hole 111 that can set up from a plurality of circumference intervals of putting out a fire evenly spouts to indoor, makes the gaseous of putting out a fire 360 scatter, is full of whole interior space rapidly, realizes putting out a fire fast.

In a further embodiment of the present invention, referring to fig. 1, 2, 9-15 and 17, the fire suppression apparatus 100 further includes a housing 15. Specifically, the cover body 15 is disposed on one side of the first cover body 131 far away from the first casing 13, a second accommodating cavity 12 is defined between the cover body 15 and the first cover body 131, a circuit board 121 and a power supply battery 122 are disposed in the second accommodating cavity 12, and the power supply battery 122 is electrically connected to the circuit board 121. The fire extinguishing core 2 is provided with a heating element 211, and two ends of the heating element 211 are respectively and electrically connected with the circuit board 121 through ignition wires 212. For example, in the example of fig. 9, 10 and 17, the first accommodation chamber 11 and the second accommodation chamber 12 are isolated from each other, and the wiring board 121 and the power supply battery 122 are provided in the second accommodation chamber 12.

Both ends of the heating element 211 are respectively connected with ignition wires 212, and the ignition wires 212 are electrically connected with the circuit board 121. For example, when the fire extinguishing core 2 in the first accommodating chamber 11 is burned, the temperature in the first accommodating chamber 11 may rapidly rise, for example, a high temperature of 1000 ℃ may be reached, but since the first accommodating chamber 11 and the second accommodating chamber 12 are isolated from each other, the high temperature in the first accommodating chamber 11 may not affect the normal operation of the circuit board 121 or the power supply battery 122. Therefore, by arranging the cover body 15 and defining the second accommodating cavity 12 between the cover body 15 and the first cover body 131, the damage of high temperature to the circuit board 121 and the power supply battery 122 in the second accommodating cavity 12 can be effectively avoided.

Alternatively, the fire extinguishing core 2 forms a k-type aerosol after ignition. The typical chemical component of the k-type aerosol is potassium nitrate.

It should be noted that the fire extinguishing apparatus 100 of the present application belongs to an aerosol extinguisher (aerosol extiguisher). An aerosol is a colloidal mixture of substances in a gas. Colloidal state is a state in which a substance exists in a liquid or gas in a finely distributed manner, wherein particles are larger than molecules and smaller than particles in suspension. In this state, the aerosol is a dry, suspended substance that in the first instance appears as a chaotic white smoke. As long as there is a significant temperature difference in the space, the material is still in suspension. The fire extinguishing mechanism is as follows: after the dry solid fire suppressant is triggered, it is discharged as a dry aerosol. Dry aerosols chemically extinguish fires by binding free radicals based on chain reactions involving the combustion process. The bound radicals block free electrons in the outer surface layer of the substance that can react with other substances, thereby interrupting the combustion process. Consists in that two main actions take place on the surface of the particles of micrometric size in the aerosol. The smaller the particle, the more effective the mechanism. Aerosol extinguishers consist of a pressureless container containing the extinguishing agent in solid form. The substance is combusted after electrical or thermal ignition. The microscopically fine extinguishing powder is discharged here at high speed in the form of a mist. The mist diffuses like a gas and is a highly effective fire suppressant. However, the field of application of these extinguishers has so far been limited to smaller enclosed spaces to achieve the desired concentration.
