As shown in FIG. 1 , an embodiment of the present application provides a starting device 100 . The starting device 100 includes: a casing 1 , a gas generating device 2 and an initiating device 3 .

Wherein, the gas generating device 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21 , and the sealed container 21 is connected with the casing 1 . The initiating device 3 cooperates with the gas generating device 2 and is used to open the sealed container 21 so that the driving medium 22 is ejected out of the sealed container 21 and forms gas.

The starting device 100 provided in the embodiment of the present application encapsulates the driving medium 22 in the integrated airtight container 21, and can open the airtight container 21 through the initiating device 3 when fire extinguishing is required, so that the driving medium 22 is sprayed out of the airtight container 21 and The gas that can drive the fire extinguishing agent 220 to be ejected is formed, and the gas can enter the fire extinguishing agent storage container 210 to rapidly pressurize the fire extinguishing agent storage container 210, and then make the fire extinguishing agent 220 spray out under the action of pressure to extinguish the fire. In this way, the fire extinguishing agent 220 does not need to be stored under pressure, thus fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing equipment, not only saving the maintenance cost of regular pressure charging, but also improving the reliability of the fire extinguishing equipment 200 .

Specifically, the starting device 100 includes a casing 1 , a gas generating device 2 and an initiating device 3 . The gas generating device 2 is a non-explosive product, specifically including a sealed container 21 and a driving medium 22 . The sealed container 21 is an integral structure, and the driving medium 22 is stored in the sealed container 21 . When a fire occurs and needs to be extinguished, the sealed container 21 can be opened by the triggering device 3, and when the sealed container 21 is opened, the pressure is released quickly, so that the driving medium 22 is ejected in the form of gas, and then the air pressure in the fire extinguishing agent storage container 210 is rapidly increased. , driving the fire extinguishing agent 220 to spray out the fire.

In this way, the fire extinguishing agent 220 does not need to be stored under pressure, it only needs to be quickly pressurized by the gas generating device 2 to be sprayed out during use, thereby solving the problem that the existing pressure storage type fire extinguishing equipment cannot be normally sprayed out due to pressure leakage. The problem of fire extinguishing agent 220 also saves the maintenance cost of regular pressurization, and can also save the pressure gauge.

The airtight container 21 of the gas generating device 2 has an integrated structure, which is a sealed whole and a complete part. There are no seal rings, sealants, seal covers, seal bolts and other structures, and can be stored independently, so there is no pressure leakage. The problem is that the driving medium 22 can be stably sealed in the airtight container 21 without leakage. The shape of the airtight container 21 is not limited, for example, the cross section of the airtight container 21 may be in the shape of a circle, an ellipse, a rectangle, a square, or a triangle. The airtight container 21 may be a metal container.

Wherein, the gas ejected by the gas generating device 2 can be more or less, and the ejection time can be long or short, which can be reasonably selected according to the amount of the driving medium 22 .

In addition, in the existing non-pressure storage type fire extinguishing equipment, the triggering device 3 is placed inside the gas generating device 2, and the gas generating device 2 is triggered to emit gas by means of electric triggering or thermal triggering. Because the gas generating device adopted by the existing non-pressure storage type fire extinguishing equipment is a pyrotechnic product, when the triggering device triggers the gas generating device, a high temperature of hundreds of degrees Celsius is instantaneously generated. The gas will explode when encountering high temperature, so it cannot be used in gas fire extinguishing equipment, only suitable for dry powder fire extinguishing equipment. In the starting device 100 provided by this solution, the triggering device 3 is placed outside the gas generating device 2, and the gas generating device 2 is a non-explosive product, and the gas generating device is triggered by opening the sealed container 21 to release the pressure of the sealed container 21 2 gas production, so it can be applied not only to dry powder fire extinguishing devices, but also to gas fire extinguishing devices and liquid fire extinguishing devices, thus greatly expanding the scope of non-storage-type fire extinguishing equipment and solving the problem that has existed for many years in the field of storage-pressure fire extinguishing equipment pressure relief problem.

In addition, compared with the existing non-storage dry powder fire extinguishing equipment, the starting device 100 of this solution can avoid the occurrence of dry powder explosion caused by improper ignition, thereby avoiding the safety hazard caused by the fire extinguishing equipment 200 exploding itself. Compared with the existing pressure-storage type gas fire extinguishing equipment, the starting device 100 of this solution can change the stored-pressure gas fire extinguishing equipment into non-storage gas fire extinguishing equipment, and fundamentally solve the pressure leakage of the gas fire extinguishing equipment Problems, and improve the fire extinguishing reliability of gas fire extinguishing equipment.

Of course, the starting device provided by the embodiment of the present application can not only be used for fire extinguishing equipment, but also can be widely used in pressurized equipment (with a pressurized container) in various fields of national economy such as energy, transportation, metallurgy, electric power, communication, etc. The existing pressurized equipment can be converted into non-pressure storage equipment, thereby solving the pressure relief problem that has plagued the industry for many years, and providing effective protection for the protection of national property and the safety of the people.

When the starting device was used for other equipment, correspondingly, the spout 115 was used to eject the material in other pressurized containers, and the driving medium 22 in the gas generating device 2 was ejected from the sealed container 21 and formed for driving other equipment containers. A gas emitted by a substance.

In a schematic example, as shown in FIG. 1 , the triggering device 3 includes: a striker 31 and a trigger 32 . Wherein, the striker 31 is provided correspondingly to the airtight container 21, and is used to puncture the airtight container 21, so that the airtight container 21 is opened. The initiator 32 cooperates with at least one of the gas generating device 2 and the firing pin 31, and is used to drive at least one of the gas generating device 2 and the firing pin 31 to move in a direction close to the other, so that the firing pin 31 punctures the seal Container 21.

In this example, the triggering device 3 comprises a striker 31 and an initiator 32 . The initiator 32 can be used to drive the striker 31 to move, so that the striker 31 approaches the sealed container 21 and punctures the sealed container 21 . Alternatively, the initiator 32 can also be used to drive the gas generating device 2 to move so that the gas generating device 2 approaches the striker 31 , so that the striker 31 punctures the sealed container 21 . Alternatively, the initiator 32 can also be used to drive the striker 31 and the gas generating device 2 to move, so that the gas generating device 2 and the striker 31 approach each other until the striker 31 pierces the sealed container 21, which is beneficial to increase the initiation speed. As long as the striker 31 and the airtight container 21 gradually approach, the striker 31 can quickly pierce the airtight container 21 by using the tip, without sparks, safe to use, and high in opening efficiency.

Of course, the triggering device 3 is not limited to the above scheme. For example, the triggering device may also include a cutter and a motor, and the motor drives the cutter to move so that the cutter cuts the sealed container to open the sealed container; or, the triggering device may also include a small electric drill, and the sealed container is opened by the electric drill.

In a schematic example, as shown in FIG. 1 , the gas generating device 2 is located in the housing 1 . The striker 31 is fixed in the housing 1 , and the initiator 32 cooperates with the gas generating device 2 to drive the gas generating device 2 to move toward the striker 31 . The gas generating device 2 is located in the housing 1 and can be protected by the housing 1 to prevent the gas generating device 2 from being accidentally opened by other structures outside the housing 1 and causing the fire extinguishing equipment 200 to be opened by mistake, resulting in property loss or personal injury.

In a schematic example, as shown in FIG. 1 , the casing 1 includes a first shell 11 and a support seat 12 , and the support seat 12 is in contact with the gas generating device 2 . Both the supporting base 12 and the gas generating device 2 are slidingly fitted with the first shell 11 . The supporting seat 12 is located in the first casing 11 and defines a sealed cavity 13 with the first casing 11 . One end of the initiator 32 is located in the sealed cavity 13 , and is used to increase the air pressure in the sealed cavity 13 to drive the support seat 12 to drive the gas generating device 2 to move toward the firing pin 31 . The other end of the initiator 32 extends out of the first casing 11 through the first casing 11 .

Splitting the shell 1 into multiple parts such as the first shell 11 and the support seat 12 not only helps to reduce the processing difficulty of each part, but also facilitates the reasonable selection of the material of each part according to the needs, and also facilitates the assembly of the internal parts of the shell 1 , so as to optimize the structure of the starting device 100 and reduce the difficulty of assembling the starting device 100 .

In one example, the first housing 11 and the support base 12 define a sealed cavity 13 . The initiator 32 is specifically used to increase the air pressure of the sealed cavity 13, and then use the raised air pressure to drive the movement of the support seat 12. Since the support seat 12 is in contact with the gas production device 2, the support seat 12 can drive the movement of the gas production device 2 , so that the driving function of the initiator 32 to the gas generating device 2 is realized, and the concept is ingenious. Wherein, the support seat 12 is used to drive the gas generating device 2 to move, so that the gas generating device 2 is isolated from the sealed cavity 13, which can prevent the temperature change in the sealed cavity 13 from causing the temperature change of the sealed container 21 and affecting the driving medium in the sealed container 21. state, thereby improving the stability of the gas generating device 2.

In one example, as shown in FIG. 1 , the support seat 12 is provided with an avoidance groove 122, which can avoid the resistance 321 of the electric initiator, and prevent the resistance 321 from being damaged during the assembly process due to insufficient space in the sealed cavity 13. damage.

In an illustrative example, as shown in FIG. 2 , a sealed container 21 includes a head 211 and a body 212. The head 211 is set corresponding to the striker 31 . The support base 12 is provided with a limiting groove 121 , and the end of the body 212 away from the head 211 is in concave-convex fit with the limiting groove 121 .

The head 211 of the airtight container 21 is arranged corresponding to the striker 31 , and can be pierced by the striker 31 to realize the opening of the airtight container 21 . The limit groove 121 of the support seat 12 can limit the airtight container 21 and increase the contact area between the support seat 12 and the airtight container 21, thereby improving the stability of the gas generating device 2 during movement and reducing the gas production The probability that the device 2 will be tilted, displaced, etc.

In one illustrative example, initiator 32 includes an electrical initiator 32 . As shown in FIG. 1 , the electric initiator 32 includes a resistor 321 and a connecting wire 322 connected to the resistor 321 . The resistor 321 is located in the sealed cavity 13 , and the connecting wire 322 extends through the housing 1 to the outside of the housing 1 .

In another illustrative example (not shown), initiator 32 includes a thermal initiator 32 .

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

The initiator 32 can be an electric initiator 32. By connecting to a power source, the resistor 321 generates heat, which increases the air pressure in the sealed cavity 13, thereby triggering the movement of the support seat 12 and the gas generating device 2, and causing the striker 31 to open the sealed container 21. Wherein, the electric initiator 32 has three indicators of starting current, safety current and resistance value. These three indicators meet the following relationship: the safe current is less than the starting current, and within the safe current indicator, the resistor 321 must not heat up after five minutes of power-on; when the current reaches or exceeds the starting current, the resistor 321 heats up; the smaller the resistance value, the larger the current, Conversely, the larger the resistance value, the smaller the current; the safety current, starting current and resistance value can be set as required.

Initiator 32 also can adopt thermal initiator 32, and thermal initiator 32 comprises thermosensitive element, is comparatively sensitive to external temperature, and when fire situation takes place, thermosensitive element can feel that external temperature rises and generate heat, makes sealing cavity 13 air pressure rises High, and then automatically cause the support seat 12 and the sealed container 21 to move, so that the striker 31 opens the sealed container 21.

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

In a schematic example, as shown in FIG. 1 , the first housing 11 includes: a housing body 111 and a first cover 112 . Wherein, the housing body 111 is provided with a first installation opening 1111 . At least a part of the gas generating device 2 is located in the housing body 111, and is slidably fitted with the housing body 111. The support base 12 is installed at the first installation opening 1111 and is slidably matched with the housing body 111 . The first cover 112 is connected to the housing body 111 , and the space between the first cover 112 and the supporting base 12 forms a sealed cavity 13 .

Splitting the first shell 11 into multiple parts such as the shell body 111 and the first cover 112 not only helps to reduce the processing difficulty of each part, but also facilitates the reasonable selection of the material of each part according to the needs, and also facilitates the internal parts of the shell 1. Assembly, so as to optimize the structure of the starting device 100 and reduce the difficulty of assembling the starting device 100 . During the assembly process, the gas generating device 2 can be inserted into the shell body 111 through the first installation opening 1111 first, then the support base 12 is installed at the first installation opening 1111 , and then the first cover 112 is covered. Wherein, the first cover 112 and the shell body 111 can be fixed by screw connection, the connection strength is high, and the assembly is convenient and fast.

In a schematic example, as shown in FIG. 1 , the housing body 111 has a cylindrical structure. The first installation opening 1111 is provided at one end of the housing body 111 , and the second installation opening 1112 is provided at the other end of the housing body 111 . The gas generating device 2 is located in the housing body 111 . The first housing 11 further includes a sealing component 113 , and the sealing component 113 seals the second installation opening 1112 . The striker 31 is located between the sealing assembly 113 and the gas generating device 2 . The sealing assembly 113 is provided with an air passage 1135 . The gas passing channel 1135 communicates with the inner space of the shell body 111 and is used to transport the gas ejected from the sealed container 21 , specifically to transport the gas used to drive the fire extinguishing agent 220 to eject to the fire extinguishing agent storage container 210 .

The shell body 111 has a cylindrical structure with openings at both ends. The two ends of the shell body 111 respectively form a first installation opening 1111 and a second installation opening 1112 . The structure is simple and easy to process and shape. The gas generating device 2 is completely installed in the shell body 111, and the two ends of the shell body 111 are respectively covered by the support seat 12 and the sealing assembly 113, which can play a good role in protecting the gas generating device 2 and effectively prevent the gas generating device 2 from Being turned on by mistake causes the fire extinguishing equipment 200 to be turned on by mistake. Correspondingly, an air passage 1135 is provided on the sealing assembly 113 to ensure that the gas ejected from the gas generating device 2 can be ejected out of the housing 1 through the air passage 1135, and then transported to the fire extinguishing agent storage container 210 to store the fire extinguishing agent. The air pressure in the container 210 increases rapidly to drive the fire extinguishing agent 220 to spray out.

Wherein, the casing body 111 may be a cylindrical structure. Correspondingly, the cross section of the airtight container 21 may be circular. In this way, there are no edges, corners and other structures between the sealed container 21 and the shell body 111 , which is beneficial to reduce the probability of sticking between the sealed container 21 and the shell body 111 , thereby improving the reliability of the starting device 100 . The striker 31 can be fixed in the housing body 111 by a bracket.

Of course, when the starting device is used for other equipment, the gas passage is used to deliver the gas formed by the driving medium (that is, the gas ejected from the sealed container) to the container body of the other equipment.

In an illustrative example, as shown in FIG. 1 , the sealing assembly 113 includes a second cover 1131 , a sealing plug 1132 and a first sealing membrane 1133 . The second cover 1131 is fixedly connected with the housing body 111 . The second cover 1131 is provided with a first avoidance gap 1134 . The sealing plug 1132 is located in the housing body 111 and is in interference fit with the housing body 111 . The air passage 1135 is arranged on the sealing plug 1132 and is arranged corresponding to the first escape notch 1134 . The striker 31 is located between the gas generating device 2 and the sealing plug 1132 . The first sealing film 1133 is sandwiched between the end surface of the shell body 111 and the second cover 1131 .

The sealing plug 1132 is in interference fit with the shell body 111, which improves the sealing reliability. The sealing plug 1132 is provided with an air passage 1135 to ensure that the gas ejected from the gas generating device 2 can be ejected from the casing 1 . The first sealing diaphragm 1133 blocks the gas passage 1135 to ensure that the gas passage 1135 will not communicate with the fire extinguishing agent storage container 210 when there is no fire. When a fire occurs and the gas generating device 2 is opened, the gas passing through the gas passage 1135 can burst the first sealing diaphragm 1133, and then enter the fire extinguishing agent storage container 210, so that the air pressure in the fire extinguishing agent storage container 210 can quickly increase to drive the fire extinguishing agent 220 to spray out. The second cover 1131 fixes the sealing plug 1132 and the first sealing diaphragm 1133 to ensure the stability of the sealing plug 1132 and the first sealing diaphragm 1133 .

Wherein, the first sealing diaphragm 1133 may be made of aluminum or other materials. The second cover 1131 can be threadedly connected with the shell body 111, the connection strength is high, and the assembly is convenient and fast. The sealing plug 1132 can be a silicone plug or a rubber plug. The striker 31 is fixedly connected to the sealing plug 1132 , and the fixed connection can be realized by means of interference fit, plastic overmolding and the like.

In one example, the drive medium 22 is a gaseous medium. The driving medium 22 can be a gaseous medium, stored in the sealed container 21, and will be sprayed out quickly when the sealed container 21 is opened. Wherein, the driving medium 22 may be a medium such as nitrogen, argon, carbon dioxide, or air, and the pressure level is higher than 1.2 MPa.

In another example, the driving medium 22 is a liquid medium. The driving medium 22 can also be a liquid medium, which can be packaged in the airtight container 21 in a liquid form. After the airtight container 21 is opened, it will be vaporized into a gas ejection, such as liquid carbon dioxide, liquid propane, and the like. In other words, the driving medium 22 is a liquid-to-gas medium.

Alternatively, the driving medium 22 can also be a solid medium, which is encapsulated in the sealed container 21 in a solid form, and sublimates into a gas ejection after the sealed container 21 is opened, such as solid carbon dioxide (dry ice). In other words, the driving medium 22 is a medium that changes from solid to gaseous state, and becomes gaseous directly through the pressure release of the sealed container, instead of generating gas through combustion or explosion, so the gas generating device 2 is still a non-explosive product.

Alternatively, the driving medium includes any combination of gaseous medium, liquid medium and solid medium. In other words, the driving medium may also include gaseous medium and liquid medium. Alternatively, the driving medium may also include gaseous medium and solid medium. Alternatively, the driving medium may also include liquid medium and solid medium. Alternatively, the driving medium may also include gaseous medium, liquid medium and solid medium. As long as the two media in different states or the media in three different states sealed in the airtight container do not react with each other, and all of them can be ejected in gaseous form after the airtight container is opened.

In one example, the Rockwell hardness of the striker 31 is greater than or equal to HR60. Setting the hardness of the striker 31 within the above range can ensure that the striker 31 can pierce the sealed container 21 quickly and effectively.

In one example, the diameter of the tip of the striker 31 is between 2mm and 3mm. Limiting the diameter of the needle tip of the striker 31 to between 2mm and 3mm can ensure that the gas can be ejected quickly after the sealed container 21 is punctured.

As shown in FIG. 4 , another embodiment of the present application provides a starting device 100 . The starting device 100 includes: a casing 1 , a gas generating device 2 and an initiating device 3 .

Wherein, the casing 1 is provided with at least one spout 115 . The gas generating device 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21 . The airtight container 21 is connected with the casing 1 . The initiating device 3 is located outside the gas generating device 2 . The triggering device 3 includes a firing pin 31 and an initiator 32 . The striker 31 is provided correspondingly to the sealed container 21, and is used to puncture the sealed container 21, so that the driving medium 22 is ejected out of the sealed container 21 and forms gas. The initiator 32 cooperates with the striker 31 and is used to drive the striker 31 to move towards the direction close to the sealed container 21 so that the striker 31 punctures the sealed container 21 .

In other words, the difference between this embodiment and the aforementioned first embodiment (as shown in FIGS. 1 and 2 ) is that the housing 1 is provided with at least one spout 115 . The triggering device 3 includes a firing pin 31 and an initiator 32 . The striker 31 is provided correspondingly to the sealed container 21, and is used to puncture the sealed container 21, so that the driving medium 22 is ejected out of the sealed container 21 and forms gas. The initiator 32 cooperates with the striker 31 and is used to drive the striker 31 to move towards the direction close to the sealed container 21 so that the striker 31 punctures the sealed container 21 .

In this embodiment, the initiator 32 is used to drive the striker 31 to move. The striker 31 can utilize the tip to puncture the sealed container 21 quickly without sparks, is safe to use, and has high opening efficiency.

The casing 1 is provided with at least one nozzle 115 , and the nozzle 115 is set to be able to communicate with the fire extinguishing agent storage container 210 , so that the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 can at least be sprayed through the nozzle 115 of the starting device 100 . The number of nozzles 115 can be one or multiple, and multiple nozzles 115 are beneficial to improve fire extinguishing efficiency.

In a schematic example, as shown in FIG. 4 , the striker 31 is located in the casing 1 and forms a sealed cavity 1111 with the casing 1 . One end of the initiator 32 is located in the sealed chamber 1111 , and is used to increase the air pressure in the sealed chamber 1111 to drive the striker 31 to move toward the sealed container 21 . The other end of the initiator 32 extends out of the casing 1 through the casing 1 .

In this embodiment, the initiator 32 is specifically used to increase the air pressure in the sealed cavity 1111 , and then use the increased air pressure to drive the striker 31 to move, which is an ingenious idea.

In one example, initiator 32 includes an electrical initiator 32 . As shown in FIG. 4 , the electric initiator 32 includes a resistor 321 and a connection wire 322 connected to the resistor 321 . The resistor 321 is located in the sealed cavity 13 , and the connection wire 322 extends through the housing 1 to the outside of the housing 1 . Of course, the initiator 32 may also include a thermal initiator 32 , or the initiator 32 includes both the above-mentioned electric initiator 32 and the above-mentioned thermal initiator 32 .

In a schematic example, as shown in FIG. 4 , the striker 31 includes: a sliding part 311 and a piercing part 312 . Wherein, the sliding part 311 and the housing 1 enclose a sealed chamber 1111 , and are slidably matched with the housing 1 . The acupuncture part 312 is connected to the sliding part 311 , and the acupuncture part 312 is disposed toward the airtight container 21 for piercing the airtight container 21 .

The striker 31 includes a sliding part 311 and a piercing part 312 , and the sliding part 311 is slidably fitted with the housing 1 to ensure that the striker 31 can move relative to the housing 1 smoothly. The acupuncture part 312 is provided corresponding to the sealed container 21 and is used to realize the piercing function of the striker 31 .

Wherein, the outer wall of the sliding part 311 can adopt a cylindrical structure, so that there are no structures such as edges and corners between the sliding part 311 and the housing 1, which is beneficial to reduce the probability of sticking between the striker 31 and the housing 1, thereby improving The reliability of the starting device 100 in use. The acupuncture part 312 may include a conical structure, which has both high strength and a sharp point.

In a schematic example, as shown in FIG. 4 , the sliding part 311 includes an end plate 3111 and a side wall 3112 . The side wall 3112 is connected to the edge of the end plate 3111, and surrounds a groove with an open end with the end plate 3111. The housing 1 seals the open end of the groove, and forms a sealed cavity 1111 with the sliding part 311 . The acupuncture portion 312 is connected to the plate surface of the end plate 3111 away from the side wall plate 3112 .

In this solution, the sliding part 311 adopts a hollow structure, and the sealing cavity 1111 is surrounded by the sliding part 311 and the housing 1. On the one hand, it is beneficial to reduce the volume of the sealing cavity 1111, thereby helping to increase the air pressure of the sealing cavity 1111. On the other hand, it is also beneficial to reduce the mass of the firing pin 31, thereby helping to reduce the air pressure value that promotes the movement of the firing pin 31, thereby increasing the triggering speed of the triggering device 3.

In one example, the end plate 3111 , the side panel 3112 and the piercing portion 312 are integrated, that is, the striker 31 is integrally formed, so that the striker 31 has higher strength and is conducive to improving assembly efficiency.

In a schematic example, as shown in FIG. 4 , the housing 1 includes a housing 11 and a sealing plug 12 . The shell 11 is provided with a first installation cavity 111 . At least a part of the sealing plug 12 and the striker 31 is located in the first installation cavity 111 . The sliding part 311 is slidingly matched with the housing 11 . The sealing plug 12 and the sliding portion 311 define a sealing cavity 1111 .

Splitting the housing 1 into several components such as the housing 11 and the sealing plug 12 not only helps to reduce the processing difficulty of each component, but also facilitates the rational selection of the material of each component according to the needs, and also facilitates the assembly of the internal components of the housing 1, thereby The structure of the starting device 100 is optimized to reduce the difficulty of assembling the starting device 100 . Using the sealing plug 12 to seal the groove of the sliding part 311 is beneficial to improve the sealing reliability of the sealing cavity 1111 . Wherein, the casing 11 may be a metal casing. The sealing plug 12 can be a rubber plug or a silicone plug.

In an illustrative example, the striker 31 can be a metal piece with high hardness, which is convenient for quickly piercing 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 chamber 1111 . The side panel 3112 of the sliding part 311 is provided with at least one sealing groove 3113 for installing a sealing ring, as shown in FIG. 4 . Wherein, the housing 11 is provided with a through hole, and the initiator 32 passes through the sealing plug 12 and extends out of the housing 1 through the through hole.

In a schematic example, as shown in FIG. 4 , the casing 1 is provided with an installation hole 131 and at least one air passage 132 . The airtight container 21 includes a head 211 and a body 212, as shown in FIG. 5 . The head 211 is installed in the installation hole 131 , and the head 211 is arranged correspondingly to the striker 31 , and is used for ejecting the gas formed by the driving medium 22 . The gas passage 132 communicates with the installation hole 131 , and one end of the gas passage 132 runs through the casing 1 , and is used to transport the gas formed by the driving medium 22 to the fire extinguishing agent storage container 210 .

The casing 1 is provided with a mounting hole 131 and an air passage 132 . The mounting hole 131 is used to install the head 211 of the sealed container 21, and the body 212 of the sealed container 21 can be inserted into the fire extinguishing agent storage container 210. The gas passage 132 is used to deliver gas to the fire extinguishing agent storage container 210 , so as to quickly pressurize the fire extinguishing agent storage container 210 and then spray the fire extinguishing agent 220 . The gas passage 132 communicates with the installation hole 131 to ensure that the gas ejected from the head 211 of the sealed container 21 can enter the gas passage 132; one end of the gas passage 132 runs through the housing 1 to ensure that the housing 1 and the fire extinguishing agent storage container After the 210 is assembled, the air passage 132 can communicate with the fire extinguishing agent storage container 210 .

In a schematic example, as shown in FIG. 4 , the casing 1 includes an outer shell 11 and a support base 13 . The housing 11 is provided with a second installation cavity 112 . The supporting seat 13 is installed in the second installation cavity 112 . The installation hole 131 and the air passage 132 are provided on the support base 13 .

Splitting the housing 1 into multiple components such as the housing 11 and the support seat 13 is not only beneficial to reduce the processing difficulty of each component, but also facilitates the reasonable selection of the material of each component according to the needs, and facilitates the assembly of the internal components of the housing 1, thereby The structure of the starting device 100 is optimized to reduce the difficulty of assembling the starting device 100 .

In a schematic example, the support base 13 is further provided with an escape hole 133 , and the escape hole 133 communicates with the installation hole 131 . The acupuncture part 312 is inserted into the escape hole 133, as shown in FIG. 4 . The avoidance hole 133 has a cross-sectional area larger than that of the installation hole 131 . The air passage 132 runs through both ends of the support base 13 along the axial direction of the escape hole 133 , and the air passage 132 penetrates the wall of the escape hole 133 along the radial direction of the escape hole 133 .

In this embodiment, the setting of the avoidance hole 133 reduces the distance between the striker 31 and the sealed container 21 , which facilitates the striker 31 to pierce the sealed container 21 quickly. At the same time, the escape hole 133 is relatively thicker, and the mounting hole 131 is relatively thinner, so that the air passage 132 can penetrate the wall of the escape hole 133 along the radial direction of the escape hole 133, so that the wall of the avoidance hole 133 is not complete in the circumferential direction. ring structure, and the hole wall of the mounting hole 131 may be a complete ring structure in the circumferential direction. Like this, the head 211 of installation hole 131 and airtight container 21 can have bigger contact area, to improve the fixing reliability of airtight container 21; In the gas channel 132, thereby increasing the initiation speed of the initiation device 3.

In one example, the escape hole 133 has a circular cross section. The cross section of the mounting hole 131 is circular. The avoidance hole 133 is arranged coaxially with the installation hole 131 , and the radius of the avoidance hole 133 is larger than the radius of the installation hole 131 . The support base 13 is threadedly connected with the shell 11, the connection is reliable and the assembly is convenient. The head 211 of the airtight container 21 is threadedly connected with the support seat 13, the connection is reliable and the assembly is convenient. There are multiple gas passages 132, and the plurality of gas passages 132 are arranged at intervals along the circumference of the support base 13, so that the gas can enter the fire extinguishing agent storage container 210 quickly and evenly.

In a schematic example, as shown in FIG. 4 , the cross-sectional area of the second mounting cavity 112 is larger than that of the first mounting cavity 111, so that the first mounting cavity 111 and the second mounting cavity 112 form a stepped hole. structure. The end surface of the support base 13 close to the first installation cavity 111 abuts against the end surface of the second installation cavity 112 . The end surface of the support seat 13 close to the first installation cavity 111 protrudes from the inner surface of the first installation cavity 111 to form a stop surface 134 for stopping the striker 31 , as shown in FIG. 4 .

During assembly, the sealing plug 12 can be firstly inserted into the first installation chamber 111 through the second installation chamber 112, then the striker 31 can be inserted into the first installation chamber 111 through the second installation chamber 112, and then the support seat 13 into the second installation cavity 112 until the support base 13 abuts against the step of the stepped hole, and then put the head 211 of the sealed container 21 into the installation hole 131 of the support base 13 . In this way, the assembly process of the starting device 100 is simple and convenient.

In addition, during use, when the striker 31 moves to abut against the support seat 13, it will be stopped by the support seat 13 and cannot continue to move, thereby limiting the sliding stroke of the striker 31 and avoiding the excessive movement range of the striker 31 causing The airtight container 21 is excessively deformed and falls off.

In one example, the piercing portion 312 of the striker 31 is provided with a transition channel 3121 connected to the air passage 132 , as shown in FIG. 4 . In this way, the gas in the sealed container 21 can also enter into the gas passage 132 through the transition passage 3121 , thereby further increasing the initiation speed of the initiation device 3 . In addition, in this way, the mass of the striker 31 can be further reduced, and the requirements for the initiator 32 can be further reduced.

In a schematic example, as shown in FIG. 4 , the casing 1 is provided with at least one discharge channel 116 , and the discharge channel 116 communicates with the nozzle 115 . The starting device 100 also includes a sealing valve 4, the sealing valve 4 is used to disconnect the communication between the discharge passage 116 and the spout 115, and the sealing valve 4 is set to conduct the discharge passage 116 and the spout 115 under the impact of the fluid (such as fire extinguishing agent 220). 115.

The discharge channel 116 is configured to be able to communicate with the fire extinguishing agent storage container 210 . The sealing valve 4 ensures that the discharge channel 116 and the nozzle 115 are disconnected when the fire extinguishing device is not in use, thereby preventing property damage or personal injury caused by the spraying of the fire extinguishing agent 220 . And in the case of a fire, after the triggering device 3 opened the sealed container 21, the fire extinguishing agent in the fire extinguishing agent storage container 210 would flow to the ejection channel 116 under the effect of air pressure, and then the sealing valve 4 would be flushed open, and the fire extinguishing agent in the fire extinguishing agent storage container 210 would flow to the ejection passage 116, and then the sealing valve 4 would be opened, and the fire extinguishing agent from the spout 115 would Spray to extinguish fire. Of course, when the activation device 100 is used for other equipment, the ejection channel 116 is set to be able to communicate with the container body of the other equipment.

In one example, the sealing valve 4 may adopt a metal sealing plug to interfere with the housing 1 . At least one sealing ring is sleeved between the sealing valve 4 and the housing 1 to further improve the sealing reliability of the sealing valve 4 . The outer wall of the sealing valve 4 is provided with a sealing groove 3113 for installing a sealing ring.

In one example, the number of ejection passages 116 can be equal to the number of nozzles 115 and correspond one-to-one. At this time, the number of sealing valves 4 can be equal to the number of ejection passages 116 and correspond one-to-one to ensure that each ejection The channel 116 and the spout 115 can be disconnected when there is no fire.

The quantity of ejection passage 116 also can be unequal with the quantity of spout 115, and such as ejection passage 116 can be three-way structure, four-way structure etc., then one ejection passage 116 can be connected with three or four spouts 115, has like this It is beneficial to reduce the quantity of the sealing valve 4, thereby simplifying the product structure and reducing the product cost.

In a schematic example, as shown in FIG. 4 , the starting device 100 further includes: a siphon tube 5 fixedly connected to the casing 1 and communicated with the discharge channel 116 .

After the activation device 100 is assembled with the fire extinguishing agent layer storage container 210 , the siphon tube 5 is inserted into the fire extinguishing agent storage container 210 . The siphon tube 5 can use the siphon principle to suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the discharge channel 116, so that the fire extinguishing agent 220 continuously enters the discharge channel 116, thereby improving the fire extinguishing efficiency. In one example, the siphon tube 5 is a plastic tube, and the siphon tube 5 is screwed to the casing 1 .

Of course, for small fire extinguishing equipment, the amount of fire extinguishing agent 220 is relatively small, and the siphon 5 can also be eliminated. Alternatively, when the fire extinguishing agent storage container 210 is on the top and the activation device 100 is on the bottom, the fire extinguishing agent 220 can automatically flow to the discharge channel 116 under the action of gravity. In this case, the siphon 5 can also be eliminated.

In a schematic example, as shown in FIG. 4 , a third installation cavity 113 and an escape 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 communication of the discharge channel 116 and the nozzle 115, and is arranged to be able to move into the avoidance chamber 117 under the impact of the fluid (such as fire extinguishing agent 220) to conduct the discharge. Channel 116 and spout 115 .

In this way, after the sealing valve 4 is impacted by the fire extinguishing agent 220, it is still located in the housing 1, which can prevent the sealing valve 4 from collapsing and causing property damage or personal injury.

In a schematic example, as shown in FIG. 4 , the starting device 100 further includes: an elastic member 6 , which is arranged in the casing 1 and abuts against the sealing valve 4 for limiting the movement of the sealing valve 4 to the escape chamber 117 .

The elastic member 6 can exert a force on the sealing valve 4, improve the positional stability of the sealing valve 4, and prevent the fire extinguishing agent 220 from spraying out by mistake when there is no fire, resulting in property loss or personal injury.

Wherein, the elastic member 6 can be a structure such as a compression spring, a shrapnel, or a silicone ball.

In a schematic example, as shown in FIG. 4 , the housing 1 includes a sealing cover 14 and a housing 11 . The housing 11 is provided with a fourth installation cavity 114 with two ends open. One end of the fourth installation cavity 114 communicates with the third installation cavity 113 , and the sealing cover 14 is used to cover the end of the fourth installation cavity 114 away from the third installation cavity 113 .

Splitting the housing 1 into multiple parts such as the shell 11 and the sealing cover 14 not only helps to reduce the processing difficulty of each part, but also facilitates the rational selection of the material of each part according to the needs, and also facilitates the assembly of the inner parts of the housing 1, thereby The structure of the starting device 100 is optimized to reduce the difficulty of assembling the starting device 100 .

During the assembly process, the sealing valve 4 can first be installed into the third installation cavity 113 through the fourth installation cavity 114, and then the elastic member 6 is loaded into the casing 11, so that the elastic member 6 is against the sealing valve 4, and then Cover sealing cover 14 and get final product.

As shown in FIG. 4 , the sealing cover 14 is provided with a limiting groove 141 , and a part of the elastic member 6 is limited in the limiting groove 141 . The limiting slot 141 can limit the elastic member 6 to prevent the elastic member 6 from tilting, shifting, etc., thereby improving the reliability of the elastic member 6 .

In a schematic example, as shown in FIG. 4 , an end of the sealing valve 4 facing the sealing cover 14 is further provided with a limiting groove 42 . One end of the elastic member 6 can be inserted into the limiting groove 42 , which is beneficial to further prevent the elastic member 6 from tilting, shifting, etc., and ensure good cooperation between the elastic member 6 and the sealing valve 4 .

In one example, as shown in FIG. 4 , an end of the sealing valve 4 facing the sealing cover 14 is further provided with a limiting boss 41 . The cross-sectional area of the limiting boss 41 is larger than the cross-sectional area of the third installation chamber 113 , which can prevent the sealing valve 4 from being stuck in the third installation chamber 113 and affect the normal spraying of the fire extinguishing agent 220 .

As shown in FIG. 7 , another embodiment of the present application provides a starting device 100 . The starting device 100 includes: a casing 1 , a gas generating device 2 and an initiating device 3 .

The housing 1 is provided with at least one nozzle 1513 , and a sealed cavity 1113 is provided in the housing 1 . As shown in FIG. 2 , the gas generating device 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21 . The airtight container 21 is connected with the casing 1 . The initiating device 3 is located outside the gas generating device 2 . The triggering device 3 includes a firing pin 31 and an initiator 32 . The striker 31 is provided correspondingly to the sealed container 21, and is used to puncture the sealed container 21, so that the driving medium 22 is ejected out of the sealed container 21 and forms gas. One end of the initiator 32 is located in the sealed chamber 1113 , and the other end of the initiator 32 extends through the housing 1 to the outside of the housing 1 , and the initiator 32 is used to raise the air pressure of the sealed chamber 1113 . The sealing cavity 1113 is provided correspondingly to the striker 31 , and is used to directly or indirectly drive the striker 31 to move toward the sealed container 21 by the elevated air pressure, so that the striker 31 punctures the sealed container 21 .

In other words, the difference between this embodiment and the foregoing first embodiment (shown in FIGS. 1 and 2 ) is:

The housing 1 is provided with at least one nozzle 1513 , and a sealed cavity 1113 is provided in the housing 1 . The triggering device 3 includes a firing pin 31 and an initiator 32 . The striker 31 is provided correspondingly to the sealed container 21, and is used to puncture the sealed container 21, so that the driving medium 22 is ejected out of the sealed container 21 and forms gas. One end of the initiator 32 is located in the sealed chamber 1113 , and the other end of the initiator 32 extends through the housing 1 to the outside of the housing 1 , and the initiator 32 is used to raise the air pressure of the sealed chamber 1113 . The sealing chamber 1113 is provided correspondingly to the striker 31 , and is used to directly or indirectly drive the striker 31 to move toward the sealed container 21 by the elevated air pressure, so that the striker 31 punctures the sealed container 21 .

The difference between this embodiment and the aforementioned second embodiment (shown in Fig. 4 and Fig. 5) is:

A sealed chamber 1113 is provided inside the casing 1 . One end of the initiator 32 is located in the sealed chamber 1113 , the other end of the initiator 32 extends through the housing 1 to the outside of the housing 1 , and the initiator 32 is used to raise the air pressure of the sealed chamber 1113 . The sealing chamber 1113 is provided correspondingly to the striker 31 , and is used to directly or indirectly drive the striker 31 to move toward the sealed container 21 by the elevated air pressure, so that the striker 31 punctures the sealed container 21 .

As shown in FIG. 7 , the triggering device 3 includes a firing pin 31 and a trigger 32 . The initiator 32 is used to drive the striker 31 to move. The striker 31 can quickly puncture the airtight container 21 by using its tip without generating sparks, so it is safe to use and has high opening efficiency.

As shown in FIG. 7 , a sealed cavity 1113 is provided in the casing 1 , and one end of the initiator 32 is located in the sealed cavity 1113 . When the end of the initiator 32 outside the sealing chamber 1113 is triggered, the initiator 32 can cause the air pressure in the sealing chamber 1113 to rise, and the air pressure raised in the sealing chamber 1113 can directly or indirectly act on the firing pin 31, and then directly or indirectly drive the firing pin 31 moves, and striker 31 is pierced airtight container 21. This avoids that the initiator 32 is directly inserted into the sealed container 21 to make the gas generating device 2 generate gas by causing the driving medium 22 to burn or explode, thereby avoiding the use of pyrotechnics as the gas generating device 2.

In a schematic example, as shown in FIG. 7 , the housing 1 is provided with a piston 16 . The piston 16 is slidingly matched with the housing 1 and forms a sealed cavity 1113 with the housing 1 . The striker 31 is fixedly connected with the piston 16 . The initiator 32 is used to increase the air pressure in the sealed cavity 1113 to drive the piston 16 to drive the striker 31 to move towards the sealed container 21 .

In this embodiment, the initiator 32 is specifically used to increase the air pressure in the sealed chamber 1113 , and then use the increased air pressure to drive the piston 16 to move. Since the piston 16 is fixedly connected with the striker 31 , the piston 16 can drive the striker 31 to move synchronously. This is equivalent to using the air pressure raised in the sealed chamber 1113 to indirectly drive the striker 31 to move toward the sealed container 21 .

Of course, when the striker 31 and the casing 1 enclose a sealed cavity 1113 , the air pressure raised in the sealed cavity 1113 can be used to directly drive the striker 31 to move toward the sealed container 21 .

Using the piston 16 to drive the striker 31 to move, compared with directly driving the striker 31 to move, not only helps to simplify the structure of the striker 31 , but also helps to improve the sealing performance of the sealing chamber 1113 .

Wherein, at least one sealing ring can be sleeved between the piston 16 and the housing 1 to further improve the sealing performance of the sealing cavity 1113 . In one example, a sealing groove for installing a sealing ring may be provided on the outer wall of the piston 16 . The striker 31 and the piston 16 can be fixedly connected by means of interference fit, plastic overmolding and the like.

In one example, initiator 32 includes an electrical initiator 32 . As shown in FIG. 4 , the electric initiator 32 includes a resistor 321 and a connection wire 322 connected to the resistor 321 . The resistor 321 is located in the sealed cavity 13 , and the connection wire 322 extends through the housing 1 to the outside of the housing 1 . Of course, the initiator 32 may also include a thermal initiator 32 , or the initiator 32 includes both the above-mentioned electric initiator 32 and the above-mentioned thermal initiator 32 .

In a schematic example, as shown in FIG. 7 , the casing 1 includes: a housing 11 and a sealing structure 12 . Wherein, the shell 11 is provided with a first installation cavity 111 . The striker 31 and the piston 16 are located in the first installation cavity 111 . One end of the first installation cavity 111 is open. The sealing structure 12 is connected to the housing 11 and seals the open end of the first installation cavity 111 . The initiator 32 passes through the sealing structure 12 . The space between the sealing structure 12 and the piston 16 forms a sealing cavity 1113 .

Splitting the housing 1 into several components such as the housing 11 and the sealing structure 12 not only helps to reduce the processing difficulty of each component, but also facilitates the rational selection of the material of each component according to the needs, and facilitates the assembly of the internal components of the housing 1, thereby The structure of the starting device 100 is optimized to reduce the difficulty of assembling the starting device 100 .

Moreover, the sealing structure 12 and the piston 16 define a sealing cavity 1113 in the housing 11 , and the sealing structure 12 and the piston 16 can seal both ends of the sealing cavity 1113 , thus improving the sealing reliability of the sealing cavity 1113 .

Wherein, the casing 11 can be a metal casing 11, and the piston 16 can be a silicone piston or a rubber piston. In one example, the striker 31 can be a metal piece with high hardness, which is convenient for quickly piercing the sealed container 21 .

In a schematic example, as shown in FIG. 7 , the sealing structure 12 includes: a first cover 121 and a sealing plug 122 . Wherein, the first cover 121 is connected with the housing 11 and is set on the open end of the first installation cavity 111 . The sealing plug 122 is at least partially located in the first installation cavity 111 and abuts against the first cover 121 . The space between the sealing plug 122 and the piston 16 forms a sealing cavity 1113 .

The sealing structure 12 includes a first cover 121 and a sealing plug 122 . The sealing plug 122 and the piston 16 define a sealing cavity 1113 in the housing 11 , and the sealing plug 122 and the piston 16 can seal both ends of the sealing cavity 1113 , thus improving the sealing reliability of the sealing cavity 1113 . The first cover 121 can fix the sealing plug 122 , prevent the sealing plug 122 from moving or falling off, and improve the reliability of the sealing plug 122 . Wherein, the sealing plug 122 may be a silicone plug or a rubber plug.

In an illustrative example, the first installation cavity 111 includes: an installation groove 1111 and a sliding channel 1112 . Wherein, the installation groove 1111 is used for installing the first cover 121 and the sealing plug 122 . The sliding channel 1112 communicates with the installation groove 1111 . The cross-sectional area of the sliding passage 1112 is smaller than that of the installation groove 1111 , so that a support surface 1114 is formed between the sliding passage 1112 and the installation groove 1111 (as shown in FIG. 9 ). The sealing plug 122 abuts against the supporting surface 1114 . The piston 16 is located in the sliding channel 1112 and is slidingly engaged with the sliding channel 1112 .

Since the cross-sectional areas of the installation groove 1111 and the sliding channel 1112 are different, the first installation cavity 111 forms a stepped hole structure. Moreover, the entrance end of the stepped hole structure is relatively thick, so that the piston 16 and the striker 31 can be quickly and conveniently inserted into the sliding channel 1112 , thereby reducing assembly difficulty and improving assembly efficiency. On the other hand, the supporting surface 1114 of the stepped hole structure also acts as a limiter for the sealing plug 122, which can prevent the sealing plug 122 from moving into the sliding channel 1112, and further improve the stability of the sealing plug 122. In addition, the supporting surface 1114 of the stepped hole also plays a role in assembling and positioning the sealing plug 122 . When the sealing plug 122 abuts against the supporting surface 1114 , it indicates that the sealing plug 122 is installed in place, which can prevent the sealing plug 122 from being excessively squeezed and affect the service life of the sealing plug 122 .

In a schematic example, as shown in FIG. 7 , the first cover 121 is provided with a limiting groove 1211 . A part of the sealing plug 122 is limited in the limiting groove 1211 . The initiator 32 passes through the sealing plug 122 and the first cover 121 . Positioning a part of the sealing plug 122 in the limiting groove 1211 of the first cover 121 is beneficial to further improve the stability of the sealing plug 122 . Moreover, this solution facilitates firstly assembling the first cover 121 , the sealing plug 122 and the initiator 32 into a module, and then assembling the module with the housing 11 , which is beneficial to reduce assembly difficulty and improve assembly efficiency. The first cover 121 may be a metal cover. The first cover 121 and the housing 11 can be screwed together, which is reliable and easy to assemble.

In a schematic example, as shown in FIG. 7 , the casing 1 is provided with an installation hole 131 and at least one air passage 132 . The airtight container 21 includes a head 211 and a body 212, as shown in FIG. 8 . The head 211 is installed in the installation hole 131 , and the head 211 is arranged correspondingly to the striker 31 , and is used for ejecting the gas formed by the driving medium 22 . The gas passage 132 communicates with the installation hole 131 , and one end of the gas passage 132 runs through the casing 1 , and is used to transport the gas formed by the driving medium 22 to the fire extinguishing agent storage container 210 .

The casing 1 is provided with a mounting hole 131 and an air passage 132 . The installation hole 131 is used for installing the head 211 of the airtight container 21 , and the body 212 of the airtight container 21 can be inserted into the fire extinguishing agent storage container 210 . The gas passage 132 is used to deliver gas to the fire extinguishing agent storage container 210 , so as to quickly pressurize the fire extinguishing agent storage container 210 and then spray the fire extinguishing agent 220 . The gas passage 132 communicates with the installation hole 131 to ensure that the gas ejected from the head 211 of the sealed container 21 can enter the gas passage 132; one end of the gas passage 132 runs through the housing 1 to ensure that the housing 1 and the fire extinguishing agent storage container After the 210 is assembled, the air passage 132 can communicate with the fire extinguishing agent storage container 210 .

In a schematic example, as shown in FIG. 7 , the casing 1 includes an outer shell 11 and a support seat 13 . The housing 11 is provided with a second installation cavity 112 . The supporting seat 13 is installed in the second installation cavity 112 . The installation hole 131 and the air passage 132 are provided on the support base 13 .

Splitting the housing 1 into multiple components such as the housing 11 and the support seat 13 is not only beneficial to reduce the processing difficulty of each component, but also facilitates the reasonable selection of the material of each component according to the needs, and facilitates the assembly of the internal components of the housing 1, thereby The structure of the starting device 100 is optimized to reduce the difficulty of assembling the starting device 100 .

In one example, the support base 13 is screwed to the housing 11, the connection is reliable and the assembly is convenient. The head 211 of the airtight container 21 is threadedly connected with the support seat 13, the connection is reliable and the assembly is convenient. The number of gas passages 132 can be multiple, and the plurality of gas passages 132 are arranged at intervals along the circumference of the support base 13, as shown in FIG.

In a schematic example, as shown in FIG. 7 , the starting device 100 further includes: a first sealing diaphragm 141 . The first sealing membrane 141 is disposed in the second installation cavity 112 and between the striker 31 and the sealed container 21 , and the first sealing membrane 141 abuts against an end of the support seat 13 close to the striker 31 . When a fire occurs, the striker 31 punctures the first sealing membrane 141 , and then punctures the sealed container 21 . The setting of the first sealing diaphragm 141 is beneficial to prevent the sealing container 21 from being pierced due to false triggering of the striker 31 , thereby improving the safety of the starting device 100 . Wherein, the first sealing diaphragm 141 may be an aluminum diaphragm or other materials.

In a schematic example, as shown in FIG. 7 , the housing 1 is provided with at least one spray channel 114 , and the spray channel 114 communicates with the nozzle 1513 . The starting device 100 also includes a second sealing membrane 142 . The second sealing diaphragm 142 is disposed corresponding to the nozzle 1513 for disconnecting the communication between the discharge channel 114 and the nozzle 1513 .

The discharge channel 114 is configured to be able to communicate with the fire extinguishing agent storage container 210 . The second sealing diaphragm 142 ensures that when the fire extinguishing device 200 is not in use, the spray channel 114 and the nozzle 1513 are disconnected, thereby preventing property damage or personal injury caused by the spray of the fire extinguishing agent 220 . And in the case of a fire, when the triggering device 3 opens the sealed container 21, the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 flows toward the ejection channel 114 under the action of air pressure, and then breaks through the second sealing diaphragm 142 , sprayed out by the spout 1513 to extinguish the fire. Of course, when the activation device 100 is used for other equipment, the discharge channel 114 is set to be able to communicate with the container body of the other equipment. Compared with the solution of using the sealing valve to disconnect the nozzle 1513 from the discharge channel 114 and further using the elastic member to improve the stability of the sealing valve, the structure of this solution is simpler. Wherein, the second sealing diaphragm 142 may be an aluminum diaphragm or other diaphragms.

In one example, the number of ejection channels 114 can be equal to and one-to-one correspond to the number of nozzles 1513, and at this time, the number of second sealing membranes 142 can be equal to and one-to-one correspond to the number of ejection channels 114, so as to ensure that each Each ejection channel 114 and the spout 1513 can be in a disconnected state when there is no fire.

The quantity of ejection passage 114 also can be unequal with the quantity of spout 1513, and such as ejection passage 114 can be three-way structure, four-way structure etc., then one ejection passage 114 can be connected with three or four spout 1513, has like this It is beneficial to reduce the quantity of the second sealing diaphragm 142, thereby simplifying the product structure and reducing the product cost.

In a schematic example, as shown in FIG. 7 , the starting device 100 further includes: a siphon tube 4 fixedly connected to the casing 1 and communicated with the discharge channel 114 .

The siphon tube 4 can use the siphon principle to suck the fire extinguishing agent 220 in the fire extinguishing agent storage container 210 into the discharge channel 114, so that the fire extinguishing agent 220 continuously enters the discharge channel 114, thereby improving the fire extinguishing efficiency. In one example, the siphon tube 4 is a plastic tube, and the siphon tube 4 is screwed to the casing 1 .

Of course, for small fire extinguishing equipment, the amount of fire extinguishing agent 220 is relatively small, and the siphon 4 can also be eliminated. Alternatively, when the fire extinguishing agent storage container 210 is on the top and the activation device 100 is on the bottom, the fire extinguishing agent 220 can automatically flow to the discharge channel 114 under the action of gravity. In this case, the siphon 4 can also be eliminated.

In a schematic example, as shown in FIG. 7 , the housing 1 includes a casing 11 and an injection structure 15 . A third installation cavity 113 for installing the injection structure 15 is provided in the housing 11 . One end of the third installation chamber 113 is open, and the other end of the third installation chamber 113 communicates with the discharge channel 114 . The nozzle 1513 is provided on the injection structure 15 . The second sealing membrane 142 is arranged between the discharge channel 114 and the spray structure 15 .

Wherein, the number of fire extinguishing agent nozzles 2106 may be one or multiple, and multiple fire extinguishing agent nozzles 2106 are beneficial to improve fire extinguishing efficiency.

In an illustrative example, as shown in FIG. 3 , the fire extinguishing agent storage container 210 includes a second housing 2102 and a third cover 2104 . The second housing 2102 has a first opening 2108 and a second opening 2110 . The starting device 100 is disposed at the first opening 2108 . The third cover 2104 is disposed at the second opening 2110 , and the third cover 2104 is provided with a fire extinguishing agent nozzle 2106 .

The air pressure raised in the sealing chamber 1113 drives the piston 16 to move towards the direction of the gas generating device 2, and the piston 16 drives the striker 31 to move synchronously, so that the striker 31 pierces the first sealing diaphragm 141 and the sealed container 21, and the gas in the sealed container 21 The driving medium 22 ejects out of the sealed container 21 and forms a gas. The ejected gas enters the fire extinguishing agent storage container 210 through the gas passage 132, rapidly pressurizes the fire extinguishing agent storage container 210, and then drives the fire extinguishing agent 220 to enter the fire extinguishing agent discharge channel 114 through the siphon 4, and breaks through the second seal The diaphragm 142 sprays out the fire through the nozzle 151 .

As shown in FIG. 12 , the embodiment of the present application also provides a fire extinguishing device, including: a casing 200 and a plurality of activation devices 100 . The shell 200 is equipped with a fire extinguishing agent, and the shell 200 is provided with a fire extinguishing agent nozzle 1513, as shown in FIG. 12 . A plurality of starting devices 100 are connected with the housing 200 and are used to deliver gas into the housing 200 to drive the fire extinguishing agent in the housing 200 to spray out through the fire extinguishing agent nozzle 1513 .

Wherein, the starting device 100 includes a gas generating device 2 and an initiating device 3 , as shown in FIG. 10 and FIG. 12 . The gas generating device 2 includes an integrated sealed container 21 and a driving medium 22 sealed in the sealed container 21 , as shown in FIG. 11 . The initiating device 3 cooperates with the gas generating device 2 and is used to open the sealed container 21 so that the driving medium 22 sprays out of the sealed container 21 and forms the gas ejected from the fire extinguishing agent in the driving housing 200 .

The fire extinguishing equipment provided in the embodiment of the present application includes a casing 200 and a plurality of starting devices 100 . The casing 200 is a storage container for the fire extinguishing agent. The casing 200 is provided with a fire extinguishing agent nozzle 1513 for spraying out the fire extinguishing agent. The starting device 100 is used to deliver gas to the housing 200, so that the fire extinguishing agent in the housing 200 is ejected through the fire extinguishing agent nozzle 1513 under the action of the gas pressure, so as to realize the function of starting the fire extinguishing equipment. Compared with a single starting device 100, since there are multiple starting devices 100 in this solution, the gas production can be effectively increased, thereby effectively increasing the air pressure in the housing 200, so that the fire extinguishing agent has a higher spray intensity, which meets high requirements. The requirements of the application site for the injection intensity of the fire extinguishing agent, thereby improving the fire extinguishing efficiency of the fire extinguishing equipment.

Moreover, since fire extinguishing equipment is used in different places, the requirements for fire extinguishing agent injection intensity are also different. With this design, the number of starting devices 100 can be adjusted according to the application places, so as to meet the requirements of different application places for fire extinguishing agent injection intensity and improve fire extinguishing efficiency.

In addition, by encapsulating the drive medium 22 in the integrated airtight container 21, the airtight container 21 can be opened by the triggering device 3 when the fire extinguishing is required, so that the drive medium 22 is sprayed out of the airtight container 21 and forms a fire extinguishing agent that can be driven to spray. Gas, the gas can enter the casing 200 to rapidly pressurize the casing 200, and then make the fire extinguishing agent spray out under the action of pressure to extinguish the fire. In this way, the fire extinguishing agent does not need to be stored under pressure, thus fundamentally solving the pressure leakage problem of the existing pressure storage type fire extinguishing equipment, not only saving the maintenance cost of regular pressure charging, but also improving the reliability of the fire extinguishing equipment.

In a schematic example, the fire extinguishing equipment further includes: a siphon 4 , as shown in FIG. 10 and FIG. 12 . One end of the siphon tube 4 is located in the casing 200 , and the other end of the siphon tube 4 communicates with the fire extinguishing agent nozzle 1513 . The siphon tube 4 can use the siphon principle to suck the fire extinguishing agent in the casing 200 into the fire extinguishing agent nozzle 1513, so that the fire extinguishing agent can be continuously sprayed out through the fire extinguishing agent nozzle 1513, thereby improving the fire extinguishing efficiency.

In one example, the siphon tube 4 is a plastic tube, and the siphon tube 4 is screwed to the casing 200 .

Of course, for small fire extinguishing equipment, the amount of fire extinguishing agent is relatively small, and the siphon 4 can also be cancelled. Or, for the case where the fire extinguishing agent nozzle 1513 is located at the bottom of the housing 200, the fire extinguishing agent can automatically flow to the fire extinguishing agent nozzle 1513 under the action of gravity, and in this case the siphon 4 can also be eliminated.

In a schematic example, the number of siphon pipes 4 is equal to the number of fire extinguishing agent nozzles 1513, and there is a one-to-one correspondence, as shown in FIG. 12 . In this way, each fire extinguishing agent nozzle 1513 can spray fire extinguishing agent continuously and efficiently, thereby effectively improving the fire extinguishing efficiency.

In one example, as shown in FIG. 12 , if the number of fire extinguishing agent nozzles 1513 is one, the number of siphon pipes 4 is also one. In another example (not shown in the figure), the number of fire extinguishing agent nozzles 1513 is multiple, such as two, and the number of siphon pipes 4 is also multiple.

Certainly, the quantity of fire extinguishing agent spout 1513 and the quantity of siphon pipe 4 also can be unequal, such as the quantity of fire extinguishing agent spout 1513 is greater than the quantity of siphon pipe 4, then part of fire extinguishing agent spout 1513 is connected with siphon pipe 4, also has part of fire extinguishing agent spout 1513 not Connected to siphon 4.

In a schematic example, the siphon pipe 4 is a straight pipe, as shown in FIG. 10 . The siphon 4 adopts a straight pipe, which has a simple structure and is easy to assemble, and can reduce the flow resistance of the fire extinguishing agent, which is conducive to the rapid ejection of the fire extinguishing agent.

In a schematic example, the siphon tube 4 is an elbow. As shown in FIG. 12 , the end of the siphon tube 4 away from the fire extinguishing agent nozzle 1513 bends and extends toward the inner side wall of the casing 200 .

The siphon tube 4 adopts an elbow, and is bent and extended toward the inner wall of the housing 200, so that when the fire extinguishing equipment is used lying flat, the end of the siphon tube 4 can face downward, thereby ensuring that the siphon tube 4 can efficiently extract the fire extinguishing agent in the housing 200 , so as to improve the fire extinguishing efficiency.

In an illustrative example, the number of starting devices 100 is two, as shown in FIG. 12 .

In one example, as shown in FIG. 12 , one activation device 100 is installed at one end of the housing 200 , and the other activation device 100 is installed at the other end of the housing 200 . In another example (not shown in the figure), two activation devices 100 are installed at the same end of the housing 200 . In yet another example (not shown in the figure), one activation device 100 is installed at the end of the housing 200 , and the other activation device 100 is installed at the middle of the housing 200 . In yet another example (not shown in the figure), the two starting devices 100 are installed in the middle of the casing 200 .

The use of two starting devices 100 can not only increase the gas production, but also improve the fire extinguishing agent injection intensity and fire extinguishing efficiency of the fire extinguishing equipment, and also avoid the structure of the fire extinguishing equipment being too complicated.

Wherein, the distribution form of the two starting devices 100 is not limited, and can be flexibly designed according to the shape of the casing 200 and other factors. Such as: can be respectively arranged at the two ends of housing 200; also can be located at the same end of housing 200; also can be located at the end of housing 200, another be located at the middle part of housing 200; also can two They are all arranged in the middle of the casing 200 ; they can also be arranged in any other position of the casing 200 . Of course, the number of starting devices 100 can also be three, four, or even more, which can be reasonably designed according to factors such as the capacity, size, and usage scenarios of the fire extinguishing equipment.

In a schematic example (not shown in the figure), the volumes of the sealed containers 21 of the two starting devices 100 are the same. The volumes of the sealed containers 21 of the two starting devices 100 can be the same, so that the types of the gas generating devices 2 can be reduced, and it is difficult to install them incorrectly during the assembly process, thus facilitating assembly.

In a schematic example, the volumes of the sealed containers 21 of the two starting devices 100 are different, as shown in FIG. 12 . The volumes of the sealed containers 21 of the two starting devices 100 may also be different, which facilitates the reasonable design of the gas production capacity of the fire extinguishing equipment as required, and also facilitates the flexible design of the installation positions of the two starting devices 100 as required.

In a schematic example, the casing 200 includes: a housing 5 and an installation cover 1 , as shown in FIG. 12 . Wherein, the housing 5 is provided with an installation opening 51 . The installation cover 1 is located at the installation opening 51 . The starting device 100 is installed on the installation cover 1 .

Splitting the casing 200 into the casing 5 and the installation cover 1 can simplify the structure of the casing 5 and the installation cover 1, and also facilitate the flexible design of the specific structure of the installation cover 1 according to assembly requirements, so as to reduce the difficulty of assembling the starting device 100. It is beneficial to ensure the integrity and sealing of the shell 5 .

In a schematic example, the number of installation openings 51 is multiple, as shown in Figure 12, the number of installation covers 1 and the number of installation openings 51 are equal and one-to-one correspondence, and each installation cover 1 can install at most one starter device 100.

In this solution, a plurality of installation openings 51 are provided, and a plurality of installation covers 1 are provided correspondingly, so as to ensure that each installation opening 51 can be covered. Moreover, compared with the scheme in which a single mounting cover 1 is installed with a plurality of starting devices 100, each mounting cover 1 is installed with at most one starting device 100 (that is, installing 0 or 1 starting device 100) in this solution, which is conducive to simplifying the single The structure of the installation cover 1 is also conducive to reducing the size of a single installation cover 1, and is also conducive to avoiding mutual interference of the gas generating devices 2 of different starting devices 100, thereby helping to optimize the structure and performance of the fire extinguishing equipment.

Wherein, the number of installation covers 1 may be equal to the number of starting devices 100 and correspond one-to-one. The quantity of installation cover 1 also can be greater than the quantity of starting device 100, then some installation cover 1 is not equipped with starting device 100, can be used for spraying fire extinguishing agent or filling fire extinguishing agent, also can be used for other purposes.

In a schematic example, the triggering device 3 includes: a firing pin 31 and a trigger 32 , as shown in FIG. 10 . Wherein, the striker 31 is provided correspondingly to the airtight container 21, and is used to puncture the airtight container 21, so that the airtight container 21 is opened. The initiator 32 cooperates with at least one of the gas generating device 2 and the firing pin 31, and is used to drive at least one of the gas generating device 2 and the firing pin 31 to move in a direction close to the other, so that the firing pin 31 punctures the seal Container 21.

In this embodiment, the triggering device 3 includes a striker 31 and an initiator 32 . The initiator 32 can be used to drive the striker 31 to move so that the striker 31 approaches the sealed container 21 and punctures the sealed container 21. Alternatively, the initiator 32 can also be used to drive the gas generating device 2 to move so that the gas generating device 2 approaches the striker 31 , so that the striker 31 punctures the sealed container 21 . Alternatively, the initiator 32 can also be used to drive the striker 31 and the gas generating device 2 to move, so that the gas generating device 2 and the striker 31 approach each other until the striker 31 pierces the sealed container 21, which is beneficial to increase the initiation speed. As long as the striker 31 and the airtight container 21 gradually approach, the striker 31 can quickly pierce the airtight container 21 by using the tip, without sparks, safe to use, and high in opening efficiency.

Of course, the triggering device 3 is not limited to the above scheme. For example, the triggering device 3 can also include a cutter and a motor, and the motor drives the cutter to move the cutter so that the sealed container 21 is opened; or, the triggering device 3 can also include a small electric drill, and the sealed container 21 is opened by the electric drill.

In a schematic example, the installation cover 1 is provided with a sealed cavity 1113 , as shown in FIG. 10 . One end of the initiator 32 is located in the sealed chamber 1113 , and the other end of the initiator 32 extends through the installation cover 1 to the outside of the installation cover 1 , and the initiator 32 is used to raise the air pressure of the sealed chamber 1113 . The sealing chamber 1113 is provided correspondingly to the striker 31 , and is used to directly or indirectly drive the striker 31 to move toward the sealed container 21 by the elevated air pressure, so that the striker 31 punctures the sealed container 21 .

When the end of the initiator 32 outside the sealed chamber 1113 is triggered, the initiator 32 can cause the air pressure in the sealed chamber 1113 to rise, and the raised air pressure in the sealed chamber 1113 can directly or indirectly act on the firing pin 31, and then directly or indirectly drive the firing pin 31 moves, and striker 31 is pierced airtight container 21. This prevents the initiator 32 from being directly inserted into the airtight container 21 to cause the gas generating device 2 to generate gas by causing the driving medium 22 to burn or explode, thereby avoiding the use of pyrotechnics as the gas generating device 2 .

In a schematic example, as shown in FIG. 10 , a piston 16 is arranged inside the installation cover 1 . The piston 16 is slidingly matched with the installation cover 1 and forms a sealed cavity 1113 with the installation cover 1 . The firing pin 31 is fixedly connected with the piston 16 ; the initiator 32 is used to increase the air pressure in the sealing chamber 1113 to drive the piston 16 to drive the firing pin 31 to move towards the sealed container 21 .

In this embodiment, the initiator 32 is specifically used to increase the air pressure in the sealed chamber 1113 , and then use the increased air pressure to drive the piston 16 to move. Since the piston 16 is fixedly connected with the striker 31 , the piston 16 can drive the striker 31 to move synchronously. This is equivalent to using the air pressure raised in the sealed chamber 1113 to indirectly drive the striker 31 to move toward the sealed container 21 . Certainly, when the sealing chamber 1113 is formed by the striker 31 and the installation cover 1 , the air pressure raised in the seal chamber 1113 can be used to directly drive the striker 31 to move toward the sealed container 21 .

Using the piston 16 to drive the striker 31 to move, compared with directly driving the striker 31 to move, not only helps to simplify the structure of the striker 31 , but also helps to improve the sealing performance of the sealing chamber 1113 .

Wherein, at least one sealing ring can be sleeved between the piston 16 and the installation cover 1 to further improve the sealing performance of the sealing cavity 1113 . In one example, a sealing groove for installing a sealing ring may be provided on the outer wall of the piston 16 . Specifically, the striker 31 and the piston 16 can be fixedly connected by means of interference fit, plastic overmolding and the like.

In one illustrative example, initiator 32 includes an electrical initiator. As shown in FIG. 10 , the electric initiator includes a resistor 321 and a connection wire 322 connected to the resistor 321 . The resistor 321 is located in the sealed cavity 1113 , and the connection wire 322 extends through the installation cover 1 to the outside of the installation cover 1 .

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

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

In a schematic example, the installation cover 1 includes: a cover body 11 and a sealing structure 12 , as shown in FIG. 10 . Wherein, the cover body 11 is provided with a first installation cavity 111, the striker 31 and the piston 16 are located in the first installation cavity 111, and the first installation cavity 111 has an open end.

The sealing structure 12 is connected to the cover body 11 and seals the open end of the first installation cavity 111 , the initiator 32 is penetrated through the sealing structure 12 , and the space between the sealing structure 12 and the piston 16 forms a sealing cavity 1113 .

Splitting the installation cover 1 into multiple parts such as the cover body 11 and the sealing structure 12 not only helps to reduce the processing difficulty of each part, but also facilitates the reasonable selection of the material of each part according to the needs, and facilitates the assembly of the inner parts of the installation cover 1. Thereby, the structure of the fire extinguishing equipment is optimized, and the difficulty of assembling the fire extinguishing equipment is reduced.

Moreover, the sealing structure 12 and the piston 16 define a sealing cavity 1113 in the installation cover 1 , and the sealing structure 12 and the piston 16 can seal both ends of the sealing cavity 1113 , thus improving the sealing reliability of the sealing cavity 1113 . Wherein, the cover body 11 can be a metal piece, and the piston 16 can be a silicone piston 16 or a rubber piston 16 . In one example, the striker 31 can be a metal piece with high hardness, which is convenient for quickly piercing the sealed container 21 .

In an illustrative example, the sealing structure 12 includes: a first cover 121 and a sealing plug 122 . Wherein, the first cover 121 is connected with the cover body 11, and is set on the open end of the first installation cavity 111; the sealing plug 122 is at least partly located in the first installation cavity 111, and abuts against the first cover 121, and is sealed. The space between the plug 122 and the piston 16 forms a sealed cavity 1113 .

The sealing structure 12 includes a first cover 121 and a sealing plug 122 . A sealing cavity 1113 is defined in the cover body 11 by the sealing plug 122 and the piston 16 , and the sealing plug 122 and the piston 16 can seal the two ends of the sealing cavity 1113 , thus improving the sealing reliability of the sealing cavity 1113 . The first cover 121 can fix the sealing plug 122 , prevent the sealing plug 122 from moving or falling off, and improve the reliability of the sealing plug 122 . Wherein, the sealing plug 122 may be a silicone plug or a rubber plug.

In an illustrative example, the first installation cavity 111 includes: an installation groove 1111 and a sliding channel 1112 . Wherein, the installation groove 1111 is used for installing the first cover 121 and the sealing plug 122 . The sliding channel 1112 communicates with the mounting groove 1111, and the cross-sectional area of the sliding channel 1112 is smaller than the cross-sectional area of the mounting groove 1111, so that a supporting surface is formed between the sliding channel 1112 and the mounting groove 1111, and the sealing plug 122 is against the supporting surface. The piston 16 is located in the sliding channel 1112 and is slidingly engaged with the sliding channel 1112 .

Since the cross-sectional areas of the installation groove 1111 and the sliding channel 1112 are different, the first installation cavity 111 forms a stepped hole structure. Moreover, the entrance end of the stepped hole structure is relatively thick, so that the piston 16 and the striker 31 can be quickly and conveniently inserted into the sliding channel 1112 , thereby reducing assembly difficulty and improving assembly efficiency. On the other hand, the supporting surface of the stepped hole structure also acts as a limit for the sealing plug 122 , which can prevent the sealing plug 122 from moving into the sliding channel 1112 , and further improve the stability of the sealing plug 122 .

In addition, the supporting surface of the stepped hole also plays an assembly and positioning role for the sealing plug 122 . When the sealing plug 122 abuts against the support surface, it indicates that the sealing plug 122 is installed in place, which can prevent the sealing plug 122 from being excessively squeezed and affect the service life of the sealing plug 122 .

In a schematic example, the first cover 121 is provided with a limiting groove 1211 , as shown in FIG. 10 . A part of the sealing plug 122 is limited in the limiting groove 1211 . The initiator 32 passes through the sealing plug 122 and the first cover 121 .

Positioning a part of the sealing plug 122 in the limiting groove 1211 of the first cover 121 is beneficial to further improve the stability of the sealing plug 122 . Moreover, this solution facilitates firstly assembling the first cover 121 , sealing plug 122 and initiator 32 into a module, and then assembling the module with the cover body 11 , which is beneficial to reduce assembly difficulty and improve assembly efficiency.

In one example, the first cover 121 may be a metal cover. The first cover 121 and the cover body 11 can be screwed together, which is reliable and easy to assemble.

In a schematic example, the installation cover 1 on which the starting device 100 is installed is provided with an installation hole 131 and at least one air passage 132 , as shown in FIG. 10 .

As shown in FIG. 11 , the airtight container 21 includes a head 211 and a body 212 . The head 211 is installed in the installation hole 131, as shown in FIG. 10 . One end of the gas passage 132 communicates with the installation hole 131 , and the other end of the gas passage 132 communicates with the inner space of the casing 5 , and is used for delivering the gas generated by the gas generating device 2 into the casing 5 .

An installation hole 131 and an air passage 132 are provided in the installation cover 1 on which the starting device 100 is installed. The installation hole 131 is used for installing the head 211 of the airtight container 21 , and the body 212 of the airtight container 21 can be inserted into the casing 5 . The gas passing channel 132 is used to deliver gas into the casing 5 to quickly pressurize the casing 5 and then spray out the fire extinguishing agent. The gas passage 132 communicates with the installation hole 131 to ensure that the gas ejected from the head 211 of the sealed container 21 can enter the gas passage 132; , to ensure that the air passage 132 can communicate with the inner space of the housing 5 after the installation cover 1 is assembled with the housing 5 .

In a schematic example, as shown in FIG. 10 , the installation cover 1 includes a cover body 11 and a support base 13 . The cover body 11 is provided with a second installation cavity 112 , the support seat 13 is installed in the second installation cavity 112 , and the installation hole 131 and the air passage 132 are arranged on the support seat 13 .

Splitting the installation cover 1 into multiple parts such as the cover body 11 and the support seat 13 not only helps to reduce the processing difficulty of each part, but also facilitates the reasonable selection of the material of each part according to the needs, and facilitates the assembly of the inner parts of the installation cover 1. Thereby, the structure of the fire extinguishing equipment is optimized, and the difficulty of assembling the fire extinguishing equipment is reduced.

In one example, the support base 13 is screwed to the cover body 11 , and the head 211 of the airtight container 21 is screwed to the support base 13 , the connection is reliable and the assembly is convenient. There are multiple gas passages 132 , and the plurality of gas passages 132 are arranged at intervals along the circumference of the support base 13 , so that the gas can enter the casing 5 quickly and evenly.

In an exemplary embodiment, the fire extinguishing device further includes: a first sealing diaphragm 141 , as shown in FIG. 10 . The first sealing membrane 141 is disposed in the second installation cavity 112 and between the striker 31 and the sealed container 21 , and the first sealing membrane 141 abuts against an end of the support seat 13 close to the striker 31 . When a fire occurs, the striker 31 punctures the first sealing membrane 141 , and then punctures the sealed container 21 . The setting of the first sealing diaphragm 141 is beneficial to prevent the sealing container 21 from being pierced due to false triggering of the striker 31 , thereby improving the safety of the starting device 100 . The first sealing diaphragm 141 may be an aluminum diaphragm or other materials.

In an exemplary embodiment, at least one installation cover 1 is provided with a fire extinguishing agent nozzle 1513, as shown in FIG. 10 and FIG. 12 . Setting the fire extinguishing agent nozzle 1513 on the installation cover 1 can avoid perforating the shell 5, which is beneficial to ensure the integrity and sealing of the shell 5.

Wherein, the fire extinguishing agent spout 1513 can be set on only one installation cover 1 , and the fire extinguishing agent spout 1513 can also be set on two or more installation covers 1 .

In an exemplary embodiment, the installation cover 1 provided with the fire extinguishing agent nozzle 1513 is also provided with at least one discharge channel 114 , as shown in FIG. 10 . The discharge channel 114 communicates with the fire extinguishing agent nozzle 1513 , and a second sealing diaphragm 142 is provided between the discharge channel 114 and the fire extinguishing agent nozzle 1513 .

The discharge passage 114 is provided so as to be able to communicate with the inner space of the casing 5 . The second sealing diaphragm 142 ensures that when the fire extinguishing equipment is not in use, the spray channel 114 is disconnected from the fire extinguishing agent nozzle 1513, thereby preventing property damage or personal injury caused by the fire extinguishing agent spraying out. And in the case of a fire, when the triggering device 3 opens the sealed container 21, the fire extinguishing agent in the casing 5 flows to the ejection channel 114 under the effect of air pressure, and then breaks through the second sealing diaphragm 142, and the fire extinguishing agent nozzle 1513 sprayed out to extinguish the fire. Compared with the solution of using the sealing valve to disconnect the fire extinguishing agent nozzle 1513 and the discharge channel 114, in one example, using the elastic member to improve the stability of the sealing valve, the structure of this solution is simpler. Wherein, the second sealing diaphragm 142 may be an aluminum diaphragm or other diaphragms.

In one example, the number of ejection passages 114 can be equal to and one-to-one corresponding to the number of fire extinguishing agent nozzles 1513. At this time, the number of second sealing diaphragms 142 can be equal to and one-to-one corresponding to the number of ejection passages 114, so that Ensure that each ejection channel 114 and the fire extinguishing agent nozzle 1513 can be in a disconnected state when there is no fire.

The quantity of ejection channel 114 also can be unequal with the quantity of fire extinguishing agent nozzle 1513, such as ejection channel 114 can be three-way structure, four-way structure etc., then one ejection channel 114 can be connected with three or four fire extinguishing agent nozzles 1513, which is beneficial to reduce the quantity of the second sealing diaphragm 142, thereby simplifying the product structure and reducing the product cost.

In an exemplary embodiment, as shown in FIG. 10 , the mounting cover 1 provided with a fire extinguishing agent nozzle 1513 includes a cover body 11 and a spraying structure 15 . The cover body 11 is provided with a third installation cavity 113 for installing the injection structure 15 . One end of the third installation chamber 113 is open, and the other end of the third installation chamber 113 communicates with the discharge channel 114 . The fire extinguishing agent nozzle 1513 is arranged on the injection structure 15 . The second sealing membrane 142 is arranged between the discharge channel 114 and the spray structure 15 .

Splitting the installation cover 1 into multiple parts such as the cover body 11 and the injection structure 15 not only helps to reduce the processing difficulty of each part, but also facilitates the reasonable selection of the material of each part according to the needs, and facilitates the assembly of the inner parts of the installation cover 1. Thereby, the structure of the fire extinguishing equipment is optimized, and the difficulty of assembling the fire extinguishing equipment is reduced.

Wherein, the second sealing diaphragm 142 can be installed first, and then the injection structure 15 can be installed.

In one example, as shown in FIG. 10 , the injection structure 15 includes: a first cover 121 and a nozzle 151 . Wherein, the second cover 152 is disposed at the open end of the third installation cavity 113 and abuts against the second sealing diaphragm 142 , and the second cover 152 is provided with a through hole. The nozzle 151 is installed at the through hole, and the nozzle 151 communicates with the third installation cavity 113 , and the fire extinguishing agent nozzle 1513 is arranged on the nozzle 151 .

The injection structure 15 includes a second cover 152 and a nozzle 151 , and the second cover 152 is fixedly connected with the cover body 11 . Installing the nozzle 151 on the second cover 152 facilitates selection of the required shape of the nozzle 151 to optimize the product structure. The second cap 152 may be screwed to the cap body 11 , and the nozzle 151 may be threaded to the second cap 152 . Threaded connection, reliable connection, easy assembly.

In one example, as shown in FIG. 10 , an input channel 1511 and an output channel 1512 may be provided in the nozzle 151 , and the input channel 1511 communicates with the third installation cavity 113 . The output channel 1512 communicates with the input channel 1511 , and the outlet of the output channel 1512 is formed as a fire extinguishing agent nozzle 1513 .
