Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail hereinafter with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be arbitrarily combined with each other.

As shown in fig. 1, one embodiment of the present invention provides an activation device 100. The starting device 100 includes: a shell 1, a gas generating device 2 and an initiating device 3.

Specifically, the housing 1 is provided with at least one spout 115. The gas-generating apparatus 2 comprises a one-piece sealed container 21 and a driving medium 22 enclosed within the sealed container 21. The sealed container 21 is connected to the housing 1. The initiating device 3 is located outside the gas generating device 2. The triggering device 3 comprises a striker 31 and an initiator 32. The striker 31 is provided corresponding to the sealed container 21, and pierces the sealed container 21 to cause the driving medium 22 to eject the sealed container 21 and form a gas. The initiator 32 cooperates with the striker 31 for driving the striker 31 in a direction approaching the hermetic container 21 so that the striker 31 pierces the hermetic container 21.

According to the starting device 100 provided by the embodiment of the invention, the driving medium 22 is packaged in the integrated sealed container 21, and when fire is required to be extinguished, the sealed container 21 can be opened through the triggering device 3, so that the driving medium 22 is sprayed out of the sealed container 21 and forms gas capable of driving the fire extinguishing agent 220 to be sprayed out, and the gas can enter the fire extinguishing agent storage container 210 to enable the fire extinguishing agent storage container 210 to be rapidly pressurized, so that the fire extinguishing agent 220 is sprayed out to extinguish the fire under the action of pressure. In this way, the fire extinguishing agent 220 does not need to be stored under pressure, thus fundamentally solving the problem of pressure leakage of the existing pressure storage type fire extinguishing equipment, saving the maintenance cost of periodical pressurization and improving the use reliability of the fire extinguishing equipment 200.

Specifically, the starting device 100 includes a housing 1, a gas generating device 2, and an initiating device 3. The housing 1 is provided with at least one nozzle 115, the nozzle 115 being arranged to be capable of communicating with the fire suppressant storage container 210, such that the fire suppressant 220 within the fire suppressant storage container 210 is at least capable of being ejected through the nozzle 115 of the activation device 100. The number of the nozzles 115 may be one or more, and a plurality of nozzles 115 is advantageous for improving the fire extinguishing efficiency.

The gas generating device 2 is a non-initiating explosive device and specifically comprises a sealed container 21 and a driving medium 22. The sealed container 21 is of an integral structure, and the driving medium 22 is stored in the sealed container 21. When a fire needs to be extinguished, the sealed container 21 can be opened through the triggering device 3, and pressure is quickly released when the sealed container 21 is opened, so that the driving medium 22 is sprayed out in a gas form, the air pressure in the fire extinguishing agent storage container 210 is quickly increased, and the fire extinguishing agent 220 is driven to be sprayed out for extinguishing.

In this way, the fire extinguishing agent 220 is not required to be stored under pressure, and can be sprayed out only by quickly pressurizing the gas generating device 2 when the fire extinguishing agent is used, so that the problem that the fire extinguishing device 200 cannot normally spray the fire extinguishing agent 220 due to pressure leakage of the existing pressure storage type fire extinguishing device is solved, the maintenance cost of periodical pressurizing is saved, and meanwhile, the pressure gauge can be omitted.

The sealing container 21 of the gas generating device 2 is an integral sealing structure, is a complete component, has no sealing ring, sealing glue, sealing cover, sealing bolt and other structures, and can be independently stored, as shown in fig. 2, so that the problem of pressure leakage does not exist, and the driving medium 22 can be stably sealed in the sealing container 21 without leakage. The shape of the sealed container 21 is not limited, and for example, the cross section of the sealed container 21 may be circular, elliptical, rectangular, square, triangular, or the like. The sealed container 21 may be a metal container.

The amount of the gas ejected from the gas generating apparatus 2 may be small or large, and the ejection time may be long or short, and may be appropriately selected according to the amount of the driving medium 22.

In addition, in the existing non-pressure-storage fire extinguishing equipment, the triggering device 3 is arranged inside the gas generating device 2, and the gas generating device 2 is triggered to spray gas in an electric triggering or thermal triggering mode. Because the gas generating device adopted by the existing non-pressure storage type fire extinguishing equipment is an initiating device, when the initiating device initiates the gas generating device, high temperature of hundreds of ℃ is instantaneously generated. The gas can explode when encountering high temperature, so the gas can not be used for gas fire-extinguishing equipment, and can only be suitable for dry powder fire-extinguishing equipment. The starting device 100 provided by the scheme is characterized in that the triggering device 3 is arranged outside the gas generating device 2, the gas generating device 2 is a non-initiating explosive device, and the gas generating device 2 is triggered to generate gas in a mode of opening the sealing container 21 to enable the sealing container 21 to release pressure, so that the starting device is not only applicable to a dry powder fire extinguishing device, but also applicable to a gas fire extinguishing device and a liquid fire extinguishing device, the range of non-pressure storage type fire extinguishing equipment is greatly expanded, and the pressure release problem of the field of pressure storage type fire extinguishing equipment for many years is solved.

In addition, compared with the existing non-pressure storage type dry powder fire extinguishing equipment, the starting device 100 can avoid the condition that the dry powder explodes due to improper ignition initiation, thereby avoiding potential safety hazards caused by the explosion of the fire extinguishing equipment 200. Compared with the existing pressure storage type gas fire-extinguishing equipment, the starting device 100 of the scheme can change the pressure storage type gas fire-extinguishing equipment into non-pressure storage type gas fire-extinguishing equipment, so that the problem of pressure leakage of the gas fire-extinguishing equipment is fundamentally solved, and the fire-extinguishing reliability of the gas fire-extinguishing equipment is improved.

Of course, the starting device provided by the embodiment of the invention not only can be used for fire extinguishing equipment, but also can be widely applied to pressure equipment (with a pressure container) in various fields of national economy such as energy, traffic, metallurgy, electric power and communication, and the existing pressure equipment can be converted into non-pressure storage equipment, so that the pressure relief problem puzzling the industry for many years is solved, and effective guarantee is provided for protecting the safety of national property and people.

When the activation device 100 is used in other equipment, the spout 115 is used to eject the material in the container of the other equipment, and the driving medium 22 in the gas generating device 2 ejects the sealed container 21 and forms gas for driving the material in the container of the other equipment.

As shown in fig. 1, the initiating device 3 includes a striker 31 and an initiator 32. The initiator 32 is used to drive the movement of the striker 31. The striker 31 can quickly pierce the sealed container 21 with the tip portion, and no spark is generated, so that the use is safe and the opening efficiency is high.

Of course, the initiator 3 is not limited to the above-described scheme. For example, the triggering device can also comprise a cutter and a motor, wherein the motor drives the cutter to move so that the cutter cuts the sealed container and the sealed container is opened; or the initiating means may comprise a mini drill by which the sealed container is opened.

In one illustrative embodiment, as shown in FIG. 1, striker 31 is located within housing 1 and encloses a sealed cavity 1111 with housing 1. One end of the initiator 32 is located in the seal chamber 1111 for elevating the air pressure in the seal chamber 1111 to drive the striker 31 in a direction approaching the sealed container 21. The other end of the initiator 32 extends through the housing 1 to the outside of the housing 1.

In this embodiment, the initiator 32 is specifically configured to raise the air pressure in the sealing chamber 1111, and thus, the striker 31 is driven to move by the raised air pressure, which is skillfully contemplated.

In one illustrative embodiment, the initiator 32 comprises an electrical initiator. As shown in fig. 1, the electric initiator includes a resistor 321 and a connection wire 322 connecting the resistor 321, the resistor 321 is located in the sealed cavity 1111, and the connection wire 322 extends through the housing 1 to the outside of the housing 1.

In another illustrative embodiment (not shown), the initiator 32 comprises a thermal initiator.

In yet another exemplary embodiment (not shown), the initiator 32 includes both the electrical and thermal initiators described above.

The initiator 32 may be an electric initiator, and by connecting to a power source, the resistor 321 heats up, so that the air pressure in the sealing cavity 1111 increases, and the firing pin 31 is triggered to move to open the sealing container 21. The electric initiator has three indexes of starting current, safety current and resistance value. These three criteria satisfy the following relationship: the safety current is smaller than the starting current, and the resistor 321 cannot generate heat when the resistor is electrified for five minutes within the safety current index; when the current reaches or exceeds the starting current, the resistor 321 heats up; the smaller the resistance value, the larger the current, whereas the larger the resistance value, the smaller the current; the safety current, the starting current and the resistance value can be set according to the needs.

The initiator 32 may also be a thermal initiator, which includes a heat-sensitive element that is sensitive to an external temperature, and when a fire occurs, the heat-sensitive element can sense that the external temperature rises to generate heat, so that the air pressure in the sealing cavity 1111 rises, and then the striker 31 is automatically triggered to move to open the sealing container 21.

Of course, the initiator 32 may also include both an electric initiator and a thermal initiator, so that the fire extinguishing device may be started manually or automatically, thereby effectively preventing the risk caused by the failure of the fire extinguishing device to start.

In one exemplary embodiment, as shown in FIG. 1, striker 31 includes: a sliding portion 311 and a needling portion 312. The sliding portion 311 encloses a sealing cavity 1111 with the housing 1, and is slidably engaged with the housing 1. The needling portion 312 is connected to the sliding portion 311, and the needling portion 312 is disposed toward the sealed container 21 for piercing the sealed container 21.

The striker 31 includes a sliding portion 311 and a needling portion 312, the sliding portion 311 being slidably engaged with the housing 1 to ensure that the striker 31 can smoothly move relative to the housing 1. The needling portion 312 is provided in correspondence with the sealed container 21 to perform the piercing function of the striker 31.

The outer sidewall of the sliding portion 311 may have a cylindrical structure, so that there are no ribs, no corners, etc. between the sliding portion 311 and the housing 1, which is beneficial to reducing the probability of jamming between the striker 31 and the housing 1, thereby improving the reliability of the starter 100. The needling 312 can include a conical structure, with both higher strength and more pointed portions.

In one illustrative embodiment, as shown in FIG. 1, the slider 311 includes an end plate 3111 and a side wall 3112. The side wall 3112 is connected to an edge of the end plate 3111, and defines a recess with one end open with the end plate 3111. The housing 1 seals the open end of the groove and encloses a sealing chamber 1111 with the sliding portion 311. The needling 312 is connected to the end plate 3111 away from the face of the sideboard 3112.

In the scheme, the sliding part 311 adopts a hollow structure, and the sliding part 311 and the shell 1 are utilized to enclose the sealing cavity 1111, so that the volume of the sealing cavity 1111 is reduced, and the air pressure rising speed of the sealing cavity 1111 is improved; on the other hand, the mass of the striker 31 is advantageously reduced, so that the air pressure value pushing the striker 31 to move is advantageously reduced, and the triggering speed of the triggering device 3 is further increased.

Further, the end plate 3111, the side wall 3112 and the needling portion 312 are integrally formed, that is, the striker 31 is integrally formed, so that the striker 31 is strong and the assembly efficiency is improved.

In an exemplary embodiment, as shown in fig. 1, the housing 1 comprises a shell 11 and a sealing plug 12. A first mounting cavity 111 is provided in the housing 11. At least a portion of the sealing plug 12 and the striker 31 are located within the first mounting cavity 111. The sliding portion 311 is slidably engaged with the housing 11. The sealing plug 12 and the sliding portion 311 enclose a sealing cavity 1111.

The shell 1 is split into a plurality of parts such as the shell 11 and the sealing plug 12, which is beneficial to reducing the processing difficulty of each part, is convenient for reasonably selecting the materials of each part according to the needs, and is convenient for assembling the parts in the shell 1, so that the structure of the starting device 100 is optimized, and the assembling difficulty of the starting device 100 is reduced. The sealing plug 12 is used to seal the groove of the sliding portion 311, which is advantageous in improving the sealing reliability of the sealing chamber 1111. Wherein the housing 11 may be a metal housing. The sealing plug 12 may be a rubber plug or a silicone plug.

Further, the striker 31 may be made of a metal member having a high hardness to facilitate rapid piercing of the sealed container 21. At least one sealing ring is sleeved between the sliding part 311 and the housing 11 to further improve the sealing reliability of the sealing cavity 1111. The side wall 3112 of the sliding portion 311 is provided with at least one sealing groove 3113 for mounting a sealing ring, as shown in fig. 1. Wherein the housing 11 is provided with a through hole through which the initiator 32 extends outside the housing 1 through the sealing plug 12.

In an exemplary embodiment, as shown in fig. 1, a mounting hole 131 and at least one gas passage 132 are provided in the housing 1. The sealed container 21 includes a head 211 and a body 212, as shown in fig. 2. The head 211 is mounted in the mounting hole 131, and the head 211 is provided corresponding to the striker 31 to eject the gas formed by the driving medium 22. The gas passing passage 132 communicates with the mounting hole 131, and one end of the gas passing passage 132 penetrates the housing 1 for delivering the gas formed by the driving medium 22 to the fire extinguishing agent storage container 210.

A mounting hole 131 and an overair passage 132 are provided in the housing 1. The mounting hole 131 is used to mount the head 211 of the hermetic container 21, and the body 212 of the hermetic container 21 can be inserted into the fire extinguishing agent storage container 210. The gas passage 132 is used for delivering gas to the fire extinguishing agent storage container 210, so that the fire extinguishing agent storage container 210 is rapidly pressurized, and then the fire extinguishing agent 220 is sprayed. The gas passing channel 132 is communicated with the mounting hole 131, so that gas sprayed from the head 211 of the sealed container 21 can enter the gas passing channel 132; one end of the gas passage 132 penetrates the housing 1, and it is ensured that the gas passage 132 can communicate with the fire extinguishing agent storage container 210 after the housing 1 is assembled with the fire extinguishing agent storage container 210.

Of course, when the starting device is used for other equipment, the overgas channel is used for conveying the gas formed by the driving medium to the container body of other equipment.

In an exemplary embodiment, as shown in fig. 1, the housing 1 includes a shell 11 and a support base 13. A second mounting cavity 112 is provided in the housing 11. The support base 13 is mounted in the second mounting cavity 112. The mounting hole 131 and the air passage 132 are provided on the support base 13.

The shell 1 is split into a plurality of parts such as the shell 11 and the supporting seat 13, which is beneficial to reducing the processing difficulty of each part, is convenient for reasonably selecting the material of each part according to the requirement, and is convenient for assembling the parts in the shell 1, thereby optimizing the structure of the starting device 100 and reducing the assembling difficulty of the starting device 100.

In an exemplary embodiment, the support base 13 is further provided with a relief hole 133, and the relief hole 133 communicates with the mounting hole 131. The needling 312 is inserted into the relief hole 133 as shown in fig. 1. The cross-sectional area of the escape hole 133 is larger than that of the mounting hole 131. The air passage 132 penetrates through two ends of the supporting seat 13 along the axial direction of the avoidance hole 133, and the air passage 132 penetrates through the wall of the avoidance hole 133 along the radial direction of the avoidance hole 133.

In this embodiment, the distance between the striker 31 and the sealing container 21 is reduced by the avoiding hole 133, so that the striker 31 can pierce the sealing container 21 quickly. Meanwhile, the avoidance hole 133 is relatively thick, the mounting hole 131 is relatively thin, and thus the gas passing channel 132 can penetrate through the wall of the avoidance hole 133 along the radial direction of the avoidance hole 133, so that the wall of the avoidance hole 133 is not a complete annular structure in the circumferential direction, and the wall of the mounting hole 131 can be a complete annular structure in the circumferential direction. In this way, the mounting hole 131 and the head 211 of the sealing container 21 may have a larger contact area to improve the fixing reliability of the sealing container 21; and the gas ejected from the head 211 in the mounting hole 131 can more easily enter the gas passing channel 132, thereby increasing the priming speed of the priming device 3.

Further, the relief hole 133 has a circular cross section. The mounting hole 131 has a circular cross section. The avoidance hole 133 is disposed coaxially with the mounting hole 131, and the radius of the avoidance hole 133 is larger than the radius of the mounting hole 131.

Further, the supporting seat 13 is in threaded connection with the shell 11, so that the connection is reliable and the assembly is convenient. The head 211 of the sealed container 21 is in threaded connection with the supporting seat 13, so that the connection is reliable and the assembly is convenient.

Further, the number of the gas passing passages 132 is plural, and the plural gas passing passages 132 are arranged at intervals along the circumferential direction of the support base 13, so that the gas can be conveniently and rapidly introduced into the fire extinguishing agent storage container 210.

In one illustrative embodiment, as shown in FIG. 1, the cross-sectional area of the second mounting cavity 112 is greater than the cross-sectional area of the first mounting cavity 111 such that the first mounting cavity 111 and the second mounting cavity 112 form a stepped bore structure. The end surface of the support seat 13 adjacent to the first mounting cavity 111 abuts against the end surface of the second mounting cavity 112. The end surface of the support seat 13 adjacent to the first mounting chamber 111 protrudes from the inner side surface of the first mounting chamber 111 to form a stop surface 134 for stopping the striker 31, as shown in fig. 1.

In assembly, the sealing plug 12 may be first inserted into the first mounting cavity 111 through the second mounting cavity 112, then the striker 31 is inserted into the first mounting cavity 111 through the second mounting cavity 112, then the support base 13 is inserted into the second mounting cavity 112 until the support base 13 abuts against the step of the stepped hole, and then the head 211 of the sealing container 21 is inserted into the mounting hole 131 of the support base 13. In this way, the assembly process of the starting device 100 is simple and easy.

In addition, when the striker 31 moves to abut against the supporting seat 13 during use, the striker cannot continue to move due to the stop of the supporting seat 13, so that the sliding stroke of the striker 31 is limited, and the problem that the sealed container 21 is excessively deformed and falls off due to the overlarge movement range of the striker 31 is avoided.

Further, the needling portion 312 of the striker 31 is provided with a transition passage 3121 communicating with the air passage 132, as shown in fig. 1. The gas in the sealed container 21 can thus also enter the overgas channel 132 through the transition channel 3121, thereby further increasing the initiation speed of the initiating device 3. In addition, this can further reduce the mass of striker 31 and further reduce the requirements on initiator 32.

In an exemplary embodiment, as shown in fig. 1, the housing 1 is provided with at least one ejection channel 116, the ejection channel 116 communicating with the ejection orifice 115. The activation device 100 further comprises a sealing valve 4, the sealing valve 4 being arranged to disconnect the discharge channel 116 from the nozzle 115, the sealing valve 4 being arranged to conduct the discharge channel 116 to the nozzle 115 under the impact of a fluid, such as a fire extinguishing agent 220.

The discharge passage 116 is provided to be capable of communicating with the fire extinguishing agent storage container 210. The sealing valve 4 ensures that the discharge passage 116 is disconnected from the discharge port 115 in a state where the fire extinguishing apparatus 200 is not in use, thereby preventing the fire extinguishing agent 220 from being discharged to cause property loss or personal injury. When a fire occurs, the fire extinguishing agent in the fire extinguishing agent storage container 210 flows to the discharge passage 116 by the air pressure after the sealed container 21 is opened by the initiator 3, and then the sealing valve 4 is opened to discharge the fire extinguishing agent from the nozzle 115. Of course, when the starting apparatus 100 is used for other devices, the ejection passage 116 is provided so as to be capable of communicating with the container body of the other devices.

The sealing valve 4 can be a metal sealing plug and is in interference fit with the shell 1.

Further, at least one sealing ring is sleeved between the sealing valve 4 and the shell 1, so that the sealing reliability of the sealing valve 4 is further improved. The outer side wall of the sealing valve 4 is provided with a sealing groove 3113 for mounting a sealing ring.

Further, the number of the ejection channels 116 may be equal to and one-to-one corresponding to the number of the ejection ports 115, and at this time, the number of the sealing valves 4 may be equal to and one-to-one corresponding to the number of the ejection channels 116, so as to ensure that each ejection channel 116 and the ejection port 115 may be in a disconnected state when there is no fire.

The number of the spraying channels 116 may be different from that of the spraying nozzles 115, for example, the spraying channels 116 may have a three-way structure, a four-way structure, etc., and one spraying channel 116 may be communicated with three or four spraying nozzles 115, which is beneficial to reducing the number of the sealing valves 4, further simplifying the product structure and reducing the product cost.

In one exemplary embodiment, as shown in fig. 1, the starting device 100 further includes: the siphon tube 5 is fixedly connected with the housing 1 and communicates with the discharge passage 116.

When the starting device 100 is assembled with the fire extinguishing agent layer storing container 210, the siphon tube 5 is inserted into the fire extinguishing agent storing container 210. The siphon tube 5 can suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the discharge passage 116 by using a siphon principle, and continuously allow the fire extinguishing agent 220 to enter the discharge passage 116, thereby improving the fire extinguishing efficiency. Further, the siphon tube 5 is a plastic tube, and the siphon tube 5 is in threaded connection with the shell 1.

Of course, for small fire extinguishing apparatus, the quantity of extinguishing agent 220 is relatively small and siphon tube 5 may be eliminated. Alternatively, in the case where the fire extinguishing agent storage container 210 is up and the starting device 100 is down, the fire extinguishing agent 220 may automatically flow to the discharge passage 116 by gravity, and in this case, the siphon tube 5 may be eliminated.

In an exemplary embodiment, as shown in fig. 1, a third installation cavity 113 and a relief cavity 117 communicating with the third installation cavity 113 are further provided in the housing 1. The sealing valve 4 is installed in the third installation cavity 113 to disconnect the discharge passage 116 from the nozzle 115, and is configured to be movable into the escape cavity 117 to communicate the discharge passage 116 with the nozzle 115 under the impact of a fluid such as a fire extinguishing agent 220.

In this way, the sealing valve 4 is still located in the housing 1 after the impact of the fire extinguishing agent 220, and thus, it is possible to prevent the sealing valve 4 from collapsing out and causing property damage or person capping.

In one exemplary embodiment, as shown in fig. 1, the starting device 100 further includes: an elastic member 6 is provided in the housing 1 and abuts against the seal valve 4 to restrict movement of the seal valve 4 to the escape chamber 117.

The elastic member 6 can apply an acting force to the sealing valve 4, so that the position stability of the sealing valve 4 is improved, and the fire extinguishing agent 220 is prevented from being sprayed out by mistake without fire, thereby causing property loss or personal injury.

The elastic member 6 may be a compression spring, a spring plate, a silica gel ball, or the like.

In an exemplary embodiment, as shown in fig. 1, the housing 1 includes a seal cover 14 and a shell 11. The housing 11 is provided with a fourth mounting cavity 114 open at both ends. One end of the fourth installation cavity 114 is communicated with the third installation cavity 113, and the sealing cover 14 is used for sealing one end of the fourth installation cavity 114 far away from the third installation cavity 113.

The shell 1 is split into a plurality of parts such as the shell 11 and the sealing cover 14, which is beneficial to reducing the processing difficulty of each part, is convenient for reasonably selecting the materials of each part according to the needs, and is convenient for assembling the parts in the shell 1, so that the structure of the starting device 100 is optimized, and the assembling difficulty of the starting device 100 is reduced.

Specifically, in the assembly process, the sealing valve 4 may be first installed into the third installation cavity 113 through the fourth installation cavity 114, then the elastic member 6 is installed into the housing 11, so that the elastic member 6 abuts against the sealing valve 4, and then the sealing cover 14 is covered.

In an exemplary embodiment, as shown in fig. 1, the sealing cover 14 is provided with a limiting groove 141, and a portion of the elastic member 6 is limited in the limiting groove 141.

The limiting groove 141 can limit the elastic member 6 to prevent the elastic member 6 from tilting and shifting, thereby improving the reliability of the elastic member 6.

Further, as shown in fig. 1, the end of the sealing valve 4 facing the sealing cover 14 is further provided with a limit groove 42. One end of the elastic piece 6 can be inserted into the limit groove 42, which is favorable for further preventing the elastic piece 6 from tilting, shifting and the like, and ensuring good matching of the elastic piece 6 and the sealing valve 4.

Further, as shown in fig. 1, the end of the sealing valve 4 facing the sealing cover 14 is further provided with a limit boss 41. The cross-sectional area of the limiting boss 41 is larger than that of the third installation cavity 113, so that the sealing valve 4 can be prevented from being blocked in the third installation cavity 113 to influence the normal ejection of the fire extinguishing agent 220.

In one illustrative embodiment, the drive medium 22 is a gaseous medium.

The driving medium 22 may be a gaseous medium stored in the sealed container 21 and rapidly ejected when the sealed container 21 is opened. The driving medium 22 may be nitrogen, argon, carbon dioxide, air, or other medium, and the pressure level is higher than 1.2MPa.

In another illustrative embodiment, the drive medium 22 is a liquid medium.

The driving medium 22 may be a liquid medium, and may be packaged in a liquid form in the sealed container 21, and the driving medium may be vaporized into a gas after the sealed container 21 is opened, such as liquid carbon dioxide, liquid propane, and the like. In other words, the driving medium 22 is a liquid to gaseous medium.

Alternatively, the driving medium 22 may be a solid medium, which is enclosed in a sealed container 21 in a solid form, and sublimated into gas after the sealed container 21 is opened, such as solid carbon dioxide (dry ice), etc. In other words, the driving medium 22 is a solid-to-gas medium, which is directly decompressed into a gas state by the sealed container, rather than generating a gas by combustion or explosion, so that the gas generating device 2 is still a non-initiating explosive device.

Or the driving medium comprises any combination of gaseous medium, liquid medium and solid medium. In other words, the driving medium may also comprise a gaseous medium and a liquid medium. Or the driving medium may also include a gaseous medium and a solid medium. Or the drive medium may also include a liquid medium and a solid medium. Or the driving medium may also include gaseous, liquid and solid media. As long as two different-state mediums or three different-state mediums sealed in the sealed container do not react with each other, and can be ejected in a gaseous form after the sealed container is opened.

In one exemplary embodiment, the Rockwell hardness of striker 31 is greater than or equal to HR60.

Setting the hardness of the striker 31 within the above range ensures that the striker 31 can pierce the sealed container 21 quickly and effectively.

In an exemplary embodiment, the diameter of the needle tip of striker 31 is between 2mm and 3 mm.

Limiting the diameter of the tip of the striker 31 to between 2mm and 3mm ensures that the gas can be rapidly ejected after the sealed container 21 is pierced.
