Background

In order to spray fire extinguishing agent to extinguish fire, the pressure storage type fire extinguishing equipment needs to fill a certain amount of gas with pressure into the container, and the pressure of the gas is generally 1.2MPa to 20 MPa. The whole fire extinguishing equipment consists of a fire extinguishing agent storage container, a container valve (bottle head valve), a pressure gauge, a fire extinguishing agent injection port, a signal feedback device and other parts, and the pressure storage type fire extinguishing equipment is stored under pressure for a long time, so that the connection part of the parts becomes a pressure leakage point.

Detailed Description

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

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

In particular, the casing 1 is provided with at least one spout 115. The gas generating device 2 comprises an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21. The hermetic container 21 is connected to the housing 1. The initiation device 3 is positioned outside the gas production device 2. The initiator assembly 3 includes a striker 31 and an initiator 32. The striker 31 is provided in correspondence with the sealed container 21, and is configured to pierce the sealed container 21 to cause the driving medium 22 to eject the sealed container 21 and form gas. The initiator 32 is coupled to the striker 31 for driving the striker 31 in a direction approaching the sealed container 21 so that the striker 31 punctures the sealed container 21.

According to the starting device 100 provided by the embodiment of the utility model, the driving medium 22 is packaged in the integrated sealed container 21, and when fire extinguishment is needed, the sealed container 21 can be opened through the initiation 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, the gas can enter the fire extinguishing agent storage container 210 to quickly pressurize the fire extinguishing agent storage container 210, and the fire extinguishing agent 220 is sprayed out under the action of pressure to extinguish the fire. Thus, the fire extinguishing agent 220 does not need to be stored under pressure, thereby fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing equipment, not only saving the maintenance cost of periodical pressurization, but also improving the use reliability of the fire extinguishing equipment 200.

Specifically, the starting device 100 comprises a housing 1, a gas generating device 2 and an initiating device 3. The housing 1 is provided with at least one nozzle 115, and the nozzle 115 is disposed to be capable of communicating with the fire extinguishing agent storage container 210 so that the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 can be sprayed through at least the nozzle 115 of the starting apparatus 100. The number of the nozzles 115 can be one or more, and the plurality of nozzles 115 is beneficial to improving the fire extinguishing efficiency.

The gas generating device 2 is a non-explosive device and specifically comprises a sealed container 21 and a driving medium 22. The sealed container 21 is of an integrated structure, and the driving medium 22 is stored in the sealed container 21. When a fire occurs and a fire is to be extinguished, the sealed container 21 can be opened through the initiation device 3, and the sealed container 21 is rapidly decompressed when being opened, so that the driving medium 22 is sprayed in a gas form, the air pressure in the fire extinguishing agent storage container 210 is rapidly increased, and the fire extinguishing agent 220 is driven to be sprayed for extinguishing the fire.

Therefore, the fire extinguishing agent 220 does not need to be stored under pressure and can be sprayed out only by quickly pressurizing through the gas generating device 2 when in use, thereby solving the problem that the fire extinguishing equipment 200 can not normally spray the fire extinguishing agent 220 due to pressure leakage of the existing pressure storage type fire extinguishing equipment, saving the maintenance cost of periodical pressurization and simultaneously saving a pressure gauge.

The sealed container 21 of the gas generating device 2 is of an integrated structure, is a sealed whole and is a complete part, and has no structures such as a sealing ring, a sealing glue, a sealing cover, a sealing bolt and the like, 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 sealed container 21 and cannot leak. The shape of the sealed container 21 is not limited, and for example, the cross section of the sealed container 21 may be circular, oval, rectangular, square, triangular, or the like. The sealed container 21 may be a metal container.

The gas generator 2 may spray more or less gas for a longer or shorter time, and may be selected according to the amount of the driving medium 22.

In addition, in the existing non-pressure storage type fire extinguishing equipment, the initiation device 3 is arranged in the gas generating device 2, and the gas is initiated to be sprayed out of the gas generating device 2 by adopting an electric initiation or thermal initiation 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 degrees centigrade is generated instantly. The gas can explode when meeting high temperature, so the gas extinguishing device can not be used, and the gas extinguishing device can only be suitable for dry powder extinguishing devices. In the starting device 100 provided by the scheme, the initiation device 3 is arranged outside the gas generation device 2, the gas generation device 2 is a non-explosive workpiece, and the gas generation device 2 is initiated to generate gas in a manner of releasing pressure of the sealing container 21 by opening the sealing container 21, so that the starting device not only can be suitable for a dry powder fire extinguishing device, but also can be suitable for a gas fire extinguishing device and a liquid fire extinguishing device, thereby greatly expanding the range of non-pressure storage type fire extinguishing equipment and solving the problem of pressure release for many years in the field of pressure storage type fire extinguishing equipment.

In addition, compare in current non-pressure storage formula dry powder fire extinguishing apparatus, starting drive 100 of this scheme of adoption can avoid the ignition to cause the improper condition that leads to the dry powder explosion to take place to the potential safety hazard that the explosion of fire extinguishing apparatus 200 self and cause has been avoided. 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, fundamentally solves the pressure leakage problem of the gas fire extinguishing equipment, and improves the fire extinguishing reliability of the gas fire extinguishing equipment.

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

When the starting device 100 is used for other equipment, correspondingly, the nozzle 115 is used for ejecting the substances in the containers of other equipment, and the driving medium 22 in the gas generating device 2 ejects the sealed container 21 and forms gas for driving the ejection of the substances in the containers of other equipment.

As shown in FIG. 1, the initiator assembly 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 rapidly pierce the sealed container 21 with the tip portion without generating sparks, and is safe in use and high in opening efficiency.

Of course, the inducing device 3 is not limited to the above-described arrangement. For example, the initiating 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; alternatively, the initiating device may comprise a small power drill by which the sealed container is opened.

In an exemplary embodiment, as shown in FIG. 1, the striker 31 is located within the housing 1 and encloses a sealed chamber 1111 with the housing 1. One end of the initiator 32 is located in the sealed chamber 1111 and is used to raise the air pressure in the sealed chamber 1111 to drive the striker 31 to move 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 increase the air pressure in the sealed chamber 1111, so as to drive the striker 31 to move by using the increased air pressure, and the concept is ingenious.

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

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

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

The initiator 32 may be an electric initiator, and by connecting a power supply, the resistor 321 heats up to increase the air pressure in the sealed chamber 1111, so as to trigger the striker 31 to move to open the sealed container 21. The electric initiator has three indexes of starting current, safe current and resistance value. These three indices satisfy the following relationships: the safe current is smaller than the starting current, and the resistor 321 is not heated when being electrified for five minutes in the safe current index; when the current reaches or exceeds the starting current, the resistor 321 heats; the smaller the resistance value is, the larger the current is, and on the contrary, the larger the resistance value is, the smaller the current is; the safe current, the starting current and the resistance value can be set according to requirements.

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

Of course, the initiator 32 may also include both an electrical initiator and a thermal initiator, so that the fire extinguishing apparatus can be started either manually or automatically, thereby effectively preventing the risk of the fire extinguishing apparatus being unable to be started.

In an exemplary embodiment, as shown in fig. 1, the striker 31 includes: a sliding portion 311 and a needling portion 312. The sliding portion 311 and the housing 1 enclose a sealed cavity 1111 and are in sliding fit with the housing 1. The needle-pricked portion 312 is connected to the sliding portion 311, and the needle-pricked portion 312 is disposed toward the sealed container 21 for pricking the sealed container 21.

The striker 31 includes a sliding portion 311 and a needle-punching portion 312, and the sliding portion 311 is slidably engaged with the housing 1 to ensure that the striker 31 can smoothly move relative to the housing 1. The puncturing part 312 is provided corresponding to the sealed container 21 and performs a puncturing function of the striker 31.

The outer side wall of the sliding part 311 may be a cylindrical structure, so that there is no edge, corner, etc. between the sliding part 311 and the housing 1, which is beneficial to reducing the probability of the jamming between the striker 31 and the housing 1, thereby improving the reliability of the starting device 100. The needle-punched portion 312 may include a conical structure having both a high strength and a pointed portion.

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

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

Further, the end plate 3111, the side wall plate 3112 and the needle punching portion 312 are of an integral structure, that is, the striker 31 is integrally formed, so that the strength of the striker 31 is high, and the assembly efficiency is improved.

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

The shell 1 is split into the shell 11, the sealing plug 12 and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1 is facilitated, so that the structure of the starting device 100 is optimized, and the assembly difficulty of the starting device 100 is reduced. The sealing plug 12 is used for sealing the groove of the sliding part 311, which is beneficial to improving the sealing reliability of the sealing cavity 1111. 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, and is convenient for quick puncturing 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 seal groove 3113 for mounting a seal 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 air passage 132 are formed in the housing 1. The sealed container 21 includes a head portion 211 and a body portion 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 for ejecting the gas formed by the driving medium 22. The gas passing passage 132 is communicated 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.

The housing 1 is provided with a mounting hole 131 and a gas passing passage 132. The mounting hole 131 is used to mount the head portion 211 of the hermetic container 21, and the body portion 212 of the hermetic container 21 can be inserted into the fire extinguishing agent storage container 210. The air passage 132 is used to supply air to the fire extinguishing agent storage container 210, so that the fire extinguishing agent storage container 210 is rapidly pressurized to spray the fire extinguishing agent 220. The gas passing channel 132 is communicated with the mounting hole 131 to ensure that gas sprayed out of the head part 211 of the sealed container 21 can enter the gas passing channel 132; one end of the air passing passage 132 penetrates the housing 1, so that the air passing 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 in other equipment, the gas passing channel is used for conveying the gas formed by the driving medium to the container body of the 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 air passage 132 axially penetrates through both ends of the support base 13 along the avoiding hole 133, and the air passage 132 radially penetrates through the hole wall of the avoiding hole 133 along the avoiding hole 133.

In this embodiment, the distance between the striker 31 and the sealed container 21 is reduced by the provision of the avoiding hole 133, which facilitates the striker 31 to rapidly puncture the sealed container 21. Meanwhile, the avoiding hole 133 is relatively thick, and the mounting hole 131 is relatively thin, so that the air passage 132 can penetrate through the hole wall of the avoiding hole 133 along the radial direction of the avoiding hole 133, the hole wall of the avoiding hole 133 is not a complete annular structure in the circumferential direction, and the hole wall of the mounting hole 131 can be a complete annular structure in the circumferential direction.

Further, the number of the air passing channels 132 is plural, and the plural air passing channels 132 are arranged at intervals along the circumference of the supporting base 13, so that the gas can be rapidly and uniformly introduced into the fire extinguishing agent storage container 210.

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

During 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 supporting seat 13 is inserted into the second mounting cavity 112 until the supporting seat 13 abuts against the step of the stepped hole, and then the head 211 of the sealed container 21 is inserted into the mounting hole 131 of the supporting seat 13. Thus, the assembly process of the starting apparatus 100 is simple and convenient.

In addition, when the striker 31 moves to abut against the support seat 13 in the use process, the striker is stopped by the support seat 13 and cannot move continuously, so that the sliding stroke of the striker 31 is limited, and the phenomenon 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 piercing portion 312 of the striker 31 is provided with a transition passage 3121 communicating with the air passage 132, as shown in fig. 1. Thus, the gas in the sealed container 21 can also enter the gas passing channel 132 through the transition channel 3121, thereby further increasing the initiation speed of the initiation device 3. In addition, this may further reduce the mass of the striker 31 and further reduce the requirements on the 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 spout 115. The actuating device 100 further comprises a sealing valve 4, the sealing valve 4 being arranged to disconnect the ejection channel 116 from the spout 115, the sealing valve 4 being arranged to conduct the ejection channel 116 from the spout 115 under the impact of a fluid, such as fire suppressant 220.

The ejection passage 116 is provided to be capable of communicating with the fire extinguishing agent storage container 210. The sealing valve 4 ensures that the spraying channel 116 is disconnected from the spraying port 115 when the fire fighting equipment 200 is not in use, thereby preventing the fire extinguishing agent 220 from being sprayed out to cause property damage or personal injury. In the case of a fire, when the initiator 3 opens the sealed container 21, the fire extinguishing agent in the fire extinguishing agent storage container 210 flows into the discharge passage 116 by the air pressure, and further, the sealed valve 4 is opened, and the fire is discharged from the discharge port 115. Of course, when the starting apparatus 100 is used in other devices, the ejection passage 116 is provided so as to be capable of communicating with the container bodies of the other devices.

The sealing valve 4 may be a metal sealing plug, and is in interference fit with the housing 1.

Further, at least one sealing ring is sleeved between the sealing valve 4 and the housing 1, so as to further improve the sealing reliability of the sealing valve 4. 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 passages 116 may be equal to and one-to-one corresponding to the number of the ejection ports 115, and in this case, the number of the sealing valves 4 may be equal to and one-to-one corresponding to the number of the ejection passages 116, so as to ensure that each ejection passage 116 and the ejection port 115 can be in a disconnected state in the absence of fire.

The number of the ejection channels 116 may also be different from the number of the nozzles 115, for example, the ejection channels 116 may have a three-way structure, a four-way structure, or the like, and one ejection channel 116 may communicate with three or four 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 an exemplary embodiment, as shown in fig. 1, the starting apparatus 100 further comprises: the siphon tube 5 is fixedly connected to the housing 1 and communicates with the discharge passage 116.

When the starting apparatus 100 is assembled with the fire extinguishing agent layer storage container 210, the siphon 5 is inserted into the fire extinguishing agent storage container 210. The siphon tube 5 can suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the spouting passage 116 by using the siphon principle, so that the fire extinguishing agent 220 is continuously introduced into the spouting passage 116, thereby improving fire extinguishing efficiency. Furthermore, the siphon 5 is a plastic pipe, and the siphon 5 is in threaded connection with the shell 1.

Of course, for small fire extinguishing installations, the amount of extinguishing agent 220 is relatively small, and the siphon 5 can also 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 toward the spouting passage 116 by gravity, in which case the siphon 5 may be eliminated.

In an exemplary embodiment, as shown in fig. 1, a third installation cavity 113 and a bypass 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 chamber 113 to disconnect the ejection passage 116 from the ejection port 115, and is provided to be movable into the bypass chamber 117 to communicate the ejection passage 116 with the ejection port 115 under the impact of a fluid (e.g., a fire extinguishing agent 220).

Thus, the sealing valve 4 remains in the housing 1 even after being impacted by the fire extinguishing agent 220, and it is possible to prevent the sealing valve 4 from bursting out to cause property loss or cover a person.

In an exemplary embodiment, as shown in fig. 1, the starting apparatus 100 further comprises: and the elastic piece 6 is arranged in the shell 1, abuts against the sealing valve 4 and is used for limiting the sealing valve 4 to move towards the avoiding cavity 117.

The elastic member 6 can apply acting force to the sealing valve 4, improve the position stability of the sealing valve 4, and prevent the fire extinguishing agent 220 from being sprayed out by mistake in the absence of fire to cause property loss or personal injury.

Wherein, the elastic piece 6 can be a compression spring, a spring plate, a silica gel ball and other structures.

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

The shell 1 is split into the shell 11, the sealing cover 14 and other parts, so that the processing difficulty of each part is reduced, the materials of each part can be reasonably selected as required, and the assembly of the parts in the shell 1 is facilitated, so that the structure of the starting device 100 is optimized, and the assembly difficulty of the starting device 100 is reduced.

Specifically, in the assembling process, the sealing valve 4 may be first installed in the third installation cavity 113 through the fourth installation cavity 114, then the elastic member 6 is installed in 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 stopper groove 141 can limit the elastic member 6, and prevent the elastic member 6 from being inclined or displaced, 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 also provided with a stopper groove 42. One end of the elastic member 6 can be inserted into the limiting groove 42, which is beneficial to further preventing the elastic member 6 from tilting, shifting and the like, and ensuring good matching of the elastic member 6 and the sealing valve 4.

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

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

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

In another exemplary embodiment, the driving medium 22 is a liquid medium.

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

Alternatively, the driving medium 22 may be a solid medium, which is enclosed in the sealed container 21 in a solid state and sublimated to be sprayed with gas after the sealed container 21 is opened, such as solid carbon dioxide (dry ice). In other words, the driving medium 22 is a medium from solid to gas, and is directly decompressed into gas through the sealed container, rather than being burned or exploded to generate gas, so that the gas generating device 2 is still a non-explosive work.

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

In one exemplary embodiment, the striker 31 has a rockwell hardness greater than or equal to HR 60.

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

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

The diameter of the tip of the striker 31 is limited to 2mm to 3mm, which ensures that the gas can be rapidly ejected after the sealed container 21 is punctured.
