Detailed ways

In order to make the objectives, technical solutions and advantages of the present utility model more clearly understood, the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.

Example 1

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

Specifically, 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 to open the sealed container 21, so that the driving medium 22 is ejected from the sealed container 21 and forms gas.

The starting device 100 provided by the embodiment of the present invention encapsulates the driving medium 22 in the integrated sealed container 21, and can open the sealed container 21 through the initiation device 3 when the fire needs to be extinguished, so that the driving medium 22 can be ejected from the sealed container 21. And form the gas that can drive the fire extinguishing agent 220 to spray out, 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 leakage pressure problem of the existing pressure-storage fire-extinguishing equipment, not only saving the maintenance cost of regular pressurization, but also improving the reliability of the fire-extinguishing equipment 200 .

Specifically, the starting device 100 includes a housing 1 , a gas producing device 2 and an initiating device 3 . The gas generating device 2 is a non-inflammable product, and specifically includes a sealed container 21 and a driving medium 22 . The sealed container 21 has an integrated structure, and the driving medium 22 is stored in the sealed container 21 . When a fire needs to be extinguished, the sealing container 21 can be opened by the triggering device 3, and the pressure is quickly released when the sealing container 21 is opened, so that the driving medium 22 is ejected in the form of gas, thereby rapidly increasing the pressure in the fire extinguishing agent storage container 210. , 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, and only needs to be quickly pressurized by the gas generating device 2 to be sprayed during use, thereby solving the problem that the fire extinguishing equipment 200 cannot be normally sprayed due to leakage of pressure in the existing pressure-storing fire-extinguishing equipment. The problem of fire extinguishing agent 220 also saves the maintenance cost of regular pressurization, and also saves the pressure gauge.

On the other hand, the sealed container 21 of the gas generating device 2 has an integrated structure, is a sealed whole, and is a complete component. It does not have structures such as sealing rings, sealants, sealing caps, sealing bolts, etc., and can be stored independently, so there is no leakage of pressure. The problem is that the driving medium 22 can be stably sealed in the airtight container 21 without leakage. The shape of the sealed container 21 is not limited, for example, the cross-section of the sealed container 21 may be circular, oval, rectangular, square, triangular, or the like. The sealed container 21 may be a metal container.

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

In addition, in the existing non-pressure storage fire extinguishing equipment, the triggering device 3 is placed inside the gas generating device 2, and the gas generating device 2 is caused to eject gas by electrical or thermal triggering. Since the gas-generating device used in the existing non-pressure storage fire-extinguishing equipment is a pyrotechnic product, a high temperature of hundreds of degrees Celsius is instantly generated when the initiating device triggers the gas-generating device. The gas will explode when it encounters high temperature, so it cannot be used for gas fire extinguishing equipment, but only for dry powder fire extinguishing equipment. On the other hand, in the starting device 100 provided in this solution, the initiating device 3 is placed outside the gas generating device 2, and the gas generating device 2 is a non-inflammatory product. 2. Gas is produced, 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-pressure storage fire extinguishing equipment, and solving the problem of the existence of pressure storage fire extinguishing equipment for many years. pressure relief problem.

In addition, compared with the existing non-pressurized dry powder fire extinguishing equipment, using the starting device 100 of this solution can avoid the dry powder explosion caused by improper ignition, thereby avoiding the potential safety hazard caused by the fire extinguishing equipment 200 self-exploding. Compared with the existing pressure storage type gas fire extinguishing equipment, by using the starting device 100 of the present solution, the pressure storage type gas fire extinguishing equipment can be changed into a non-pressure storage type gas fire extinguishing equipment, which fundamentally solves the leakage pressure of the gas fire extinguishing equipment. problem, and improve the fire extinguishing reliability of gas fire extinguishing equipment.

Of course, the starting device provided by the embodiment of the present invention can not only be used for fire extinguishing equipment, but also can be widely used in pressurized equipment (with pressurized containers) in various fields of the national economy such as energy, transportation, metallurgy, electric power, and communication. , which can transform the existing pressure equipment into non-pressure storage equipment, so as to solve the pressure relief problem that has plagued the industry for many years, and provide an effective guarantee for the protection of national property and the safety of the people.

When the starting device is used for other equipment, correspondingly, the spout 115 is used to spray the substances in other pressurized containers, and the driving medium 22 in the gas generating device 2 is sprayed out of the sealed container 21 and forms a space for driving other equipment in the container. Gas emitted from a substance.

In a schematic example, as shown in FIG. 1 , the initiation device 3 includes: a striker 31 and an initiator 32 . Wherein, the striker 31 is arranged corresponding to the sealed container 21, and is used for piercing the sealed container 21, so that the sealed container 21 is opened. The initiator 32 cooperates with at least one of the gas generating device 2 and the striker 31 to drive at least one of the gas generating device 2 and the striker 31 to move in a direction close to the other, so that the striker 31 pierces the seal container 21.

In this example, the initiation 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 pierces 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 is close to the striker 31 , so that the striker 31 can pierce the sealed container 21 . Alternatively, the initiator 32 can also be used to drive the firing pin 31 and the gas generating device 2 to move at the same time, so that the gas producing device 2 and the firing pin 31 are close to each other until the firing pin 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 are gradually approached, the striker 31 can quickly pierce the airtight container 21 with its tip without generating sparks, which is safe to use and has high opening efficiency.

Of course, the initiating device 3 is not limited to the above solution. For example, the initiation 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, so that the sealed container is opened; or, the initiation 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 firing pin 31 is fixed in the housing 1, and the initiator 32 cooperates with the gas producing device 2 to drive the gas producing device 2 to move in a direction close to the firing pin 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 , which may cause the fire extinguishing equipment 200 to be accidentally opened, resulting in property damage or personal injury.

In a schematic example, as shown in FIG. 1 , the housing 1 includes a first housing 11 and a support base 12 , and the support base 12 is in contact with the gas generating device 2 . Both the support base 12 and the gas generating device 2 are in sliding fit with the first housing 11 . The support base 12 is located in the first casing 11 and defines a sealing cavity 13 with the first casing 11 . One end of the initiator 32 is located in the sealing chamber 13 , and is used to increase the air pressure of the sealing chamber 13 to drive the support base 12 to drive the gas generating device 2 to move in a direction close to the striker 31 . The other end of the initiator 32 extends through the first housing 11 to the outside of the first housing 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 rational selection of the material of each part according to the needs, and also facilitates the assembly of the internal parts of the shell 1. , thereby optimizing the structure of the starting device 100 and reducing the assembly difficulty of the starting device 100 .

Further, a sealing cavity 13 is defined by the first casing 11 and the support base 12 . The initiator 32 is specifically used to increase the air pressure of the sealing chamber 13, and then use the increased air pressure to drive the support seat 12 to move. Since the support seat 12 is in contact with the gas generator 2, the support seat 12 can drive the gas generator 2 to move. , so as to realize the driving function of the initiator 32 to the gas generating device 2 , which is ingeniously conceived. 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 sealing cavity 13, which can prevent the temperature change in the sealing cavity 13 from causing the temperature change of the sealing container 21 to affect the driving device in the sealing container 21. state, thereby improving the stability of the gas generator 2.

Further, as shown in FIG. 1 , the support base 12 is provided with an escape groove 122 , and the escape groove 122 can avoid the resistance 321 of the electric initiator to prevent the resistance 321 from being damaged during the assembly process due to insufficient space in the sealed cavity 13 .

In one illustrative example, as shown in FIG. 2 , the sealed container 21 includes a head 211 and a body 212. The head 211 is provided corresponding to the striker 31 . The support base 12 is provided with a limiting groove 121 , and one 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 sealed container 21 is disposed corresponding to the striker 31 and can be pierced by the striker 31 to realize the opening of the sealed container 21 . The limiting groove 121 of the support seat 12 can limit the position of the sealed container 21 and increase the contact area between the support seat 12 and the sealed container 21, thereby improving the stability of the gas generating device 2 during movement and reducing gas production The probability that the device 2 will tilt, shift, etc.

In one illustrative example, initiator 32 includes electrical initiator 32 . As shown in FIG. 1 , the electrical 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 casing 1 to the outside of the casing 1 .

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

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

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 of the sealed cavity 13, thereby causing the support seat 12 and the gas generating device 2 to move, so that the striker 31 opens the sealed container 21. Among them, the electric initiator 32 has three indexes of starting current, safe current and resistance value. These three indicators satisfy the following relationship: the safe current is less than the starting current, and within the safe current index, the resistor 321 must not heat up after energizing for five minutes; when the current reaches or exceeds the starting current, the resistor 321 heats up; the smaller the resistance value, the greater 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.

The initiator 32 can also be a thermal initiator 32. The thermal initiator 32 includes a heat-sensitive element, which is more sensitive to the outside temperature. When a fire occurs, the heat-sensitive element can sense the rise of the outside temperature and generate heat, so that the air pressure of the sealed cavity 13 rises. The height of the support base 12 and the sealed container 21 is automatically caused to move, so that the striker 31 opens the sealed container 21 .

Of course, the initiator 32 may 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 of the fire extinguishing device failing to be activated.

In a schematic example, as shown in FIG. 1 , the first housing 11 includes: a housing body 111 and a first cover 112 . The casing body 111 is provided with a first installation opening 1111 . At least a part of the gas generating device 2 is located in the casing body 111 and is in sliding fit with the casing body 111 . The support base 12 is installed at the first installation opening 1111 and is slidably fitted with the housing body 111 . The first cover 112 is connected to the shell body 111 , and the space between the first cover 112 and the support 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 rational selection of the material of each part according to the needs, and also facilitates the maintenance of the internal parts of the shell 1 . assembly, thereby optimizing the structure of the starting device 100 and reducing the assembly difficulty of the starting device 100 . During the assembly process, the gas generator 2 can be installed into the housing 111 through the first installation opening 1111 first, then the support base 12 can be installed at the first installation opening 1111 , and then the first cover 112 can be 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 quick.

In a schematic example, as shown in FIG. 1 , the casing 111 has a cylindrical structure. The first installation port 1111 is provided at one end of the case body 111 , and the other end of the case body 111 is provided with a second installation port 1112 . The gas generating device 2 is located in the casing body 111 . The first housing 11 further includes a sealing assembly 113 , and the sealing assembly 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 passage 1135 communicates with the inner space of the casing 111 and is used for conveying the gas ejected from the sealed container 21 , and specifically for conveying the gas used for driving the ejection of the extinguishing agent 220 to the fire extinguishing agent storage container 210 .

The shell body 111 has a cylindrical structure, and both ends are open, so the two ends of the shell body 111 respectively form a first installation port 1111 and a second installation port 1112 , which has a simple structure and is easy to be processed and formed. The gas generating device 2 is completely arranged 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, so that the gas generating device 2 can be well protected, and the gas generating device 2 can be effectively prevented. 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, so that the fire extinguishing agent can be stored The air pressure in the container 210 is rapidly increased to drive the fire extinguishing agent 220 to be ejected.

Wherein, the shell body 111 may be a cylindrical structure. Accordingly, the cross-section of the sealed 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 jamming between the sealed container 21 and the shell body 111 , thereby improving the use reliability of the starting device 100 . The striker 31 can be fixed in the housing 111 through a bracket.

Of course, when the starting device is used in other equipment, the gas passage is used to transport the gas formed by the driving medium (ie, 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 diaphragm 1133 . The second cover 1131 is fixedly connected with the casing body 111 . The second cover 1131 is provided with a first escape notch 1134 . The sealing plug 1132 is located in the housing body 111 and is in an 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 membrane 1133 is sandwiched between the end face of the casing body 111 and the second cover 1131 .

The sealing plug 1132 is in an interference fit with the housing body 111 to improve the sealing reliability. The sealing plug 1132 is provided with a gas passage 1135 to ensure that the gas ejected by the gas generating device 2 can be ejected out of the casing 1 . The first sealing membrane 1133 acts as a block to the air passage 1135 to ensure that the air 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 turned on, the gas passing through the gas passage 1135 can burst the first sealing membrane 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 be quickly Increase, the fire extinguishing agent 220 is driven to eject. The second cover 1131 plays a role in fixing the sealing plug 1132 and the first sealing diaphragm 1133, so as to ensure the stability of the sealing plug 1132 and the first sealing diaphragm 1133.

Wherein, the first sealing diaphragm 1133 can be made of aluminum diaphragm 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 quick. The sealing plug 1132 can be a silicone plug or a rubber plug. The striker 31 and the sealing plug 1132 are fixedly connected, and specifically, the fixed connection can be achieved by means of interference fit, overmolding, or the like.

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

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

In another illustrative 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 is vaporized into a gas, such as liquid carbon dioxide, liquid propane, and the like. In other words, the driving medium 22 is a liquid-to-gaseous medium.

Alternatively, the driving medium 22 can also be a solid medium, which is encapsulated in the sealed container 21 in a solid form, and is sublimated into a gas, such as solid carbon dioxide (dry ice), after the sealed container 21 is opened. In other words, the driving medium 22 is a solid-to-gaseous medium, which is directly transformed into a gaseous state by decompressing a sealed container, rather than generating gas through combustion or explosion, so the gas generating device 2 is still a non-inflammable product.

Alternatively, the drive medium includes any combination of gaseous, liquid, and solid media. In other words, the driving medium may also include gaseous media and liquid media. Alternatively, the drive medium may also include gaseous and solid media. 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 an illustrative 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 quickly and effectively pierce the sealed container 21 .

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

The diameter of the needle tip of the striker 31 is limited between 2 mm and 3 mm, which can ensure that the gas can be quickly ejected after the sealed container 21 is pierced.

Embodiment 2

As shown in FIG. 4, another embodiment of the present invention provides a starting device 100'. The starting device 100' includes: a housing 1', a gas producing device 2' and an initiating device 3'.

Specifically, the housing 1' is provided with at least one spout 115'. The gas generating device 2' includes an integral sealed container 21' and a driving medium 22' sealed in the sealed container 21'. The sealed container 21' is connected to the housing 1'. The initiating device 3' is located outside the gas producing device 2'.

The difference from the first embodiment is:

The initiation device 3' includes a striker 31' and an initiator 32'. The striker 31' is arranged corresponding to the sealed container 21', and is used to pierce the sealed container 21', so that the driving medium 22' is ejected from the sealed container 21' and forms gas. The trigger 32' cooperates with the striker 31' and is used to drive the striker 31' to move in a direction close to the sealed container 21', so that the striker 31' pierces the sealed container 21'.

The initiator 32' is used to drive the striker 31' to move. The striker 31' can quickly pierce the sealed container 21' with the tip part without generating sparks, which is safe to use and has high opening efficiency.

In a schematic example, further, as shown in FIG. 4 , the striker 31' is located in the housing 1', and defines a sealing cavity 1111' with the housing 1'. One end of the initiator 32' is located in the sealing chamber 1111', and is used to increase the air pressure of the sealing chamber 1111', so as to drive the striker 31' to move toward the direction close to the sealing container 21'. The other end of the initiator 32' extends through the housing 1' to the outside of the housing 1'.

In this embodiment, the initiator 32' is specifically used to increase the air pressure of the sealed cavity 1111', and then use the raised air pressure to drive the movement of the striker 31', which is ingeniously conceived.

In an illustrative example, further, as shown in FIG. 4 , the striker 31' includes: a sliding portion 311' and a needle-punching portion 312'. The sliding portion 311' and the casing 1' define a sealing cavity 1111', and are slidably matched with the casing 1'. The acupuncture part 312' is connected with the sliding part 311', and the acupuncture part 312' is arranged toward the sealed container 21', and is used for piercing the sealed container 21'.

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

The outer side wall of the sliding part 311' can adopt a cylindrical structure, so that there are no edges, corners and other structures between the sliding part 311' and the casing 1', which is beneficial to reduce the jamming between the striker 31' and the casing 1' probability, thereby improving the reliability of the starting device 100'. The needling portion 312' may comprise a conical structure with both higher strength and a sharper point.

In an illustrative example, further, 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 forms a groove with one end open with the end plate 3111'. The casing 1' seals the open end of the groove, and forms a sealing cavity 1111' with the sliding part 311'. The needle-punched portion 312' is connected to the plate surface of the end plate 3111' facing away from the side wall 3112'.

In this solution, the sliding portion 311 ′ adopts a hollow structure, and the sealing cavity 1111 ′ is surrounded by the sliding portion 311 ′ and the housing 1 ′. On the other hand, it is also beneficial to reduce the mass of the striker 31', thereby helping to reduce the air pressure value that pushes the striker 31' to move, thereby increasing the triggering speed of the triggering device 3'.

Further, the end plate 3111', the side wall 3112' and the acupuncture part 312' are of one-piece structure, that is, the striker 31' is integrally formed, so that the striker 31' has high strength and is conducive to improving assembly efficiency.

In an illustrative example, further, as shown in Fig. 4, the housing 1' includes a housing 11' and a sealing plug 12'. A first installation cavity 111' is provided in the housing 11'. At least a portion of the sealing plug 12' and the striker 31' is located in the first mounting cavity 111'. The sliding portion 311' is slidably fitted with the housing 11'. The sealing plug 12' and the sliding portion 311' define a sealing cavity 1111'.

Splitting the casing 1' into multiple parts such as the casing 11' and the sealing plug 12' 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 internal components of the casing 1'. Therefore, the structure of the starting device 100' is optimized, and the assembly difficulty of the starting device 100' is reduced. Using the sealing plug 12' to block the groove of the sliding portion 311' is beneficial to improve the sealing reliability of the sealing cavity 1111'. Wherein, the shell 11' can be a metal shell. The sealing plug 12' may be a rubber plug or a silicone plug.

In an illustrative example, further, the striker 31' can be made of 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', so as to further improve the sealing reliability of the sealing cavity 1111'. The side wall 3112' of the sliding part 311' is provided with at least one sealing groove 3113' for installing the sealing ring, as shown in Fig. 4 . The casing 11' is provided with a through hole, the initiator 32' passes through the sealing plug 12' and the through hole extends to the outside of the casing 1'.

In an illustrative example, further, as shown in FIG. 4 , the housing 1' is provided with a mounting hole 131' and at least one air passage 132'. The sealed container 21' includes a head 211' and a body 212', as shown in Figure 5 . The head 211' is installed in the installation hole 131', and the head 211' is arranged corresponding to the striker 31', and is used for ejecting the gas formed by the driving medium 22'. The gas passage 132' communicates with the mounting hole 131', and one end of the gas passage 132' penetrates the housing 1', and is used to deliver the gas formed by the driving medium 22' to the fire extinguishing agent storage container 210'.

The housing 1' is provided with a mounting hole 131' and an air passage 132'. The mounting hole 131' is used to mount 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 that the fire extinguishing agent storage container 210' is rapidly pressurized, and then the fire extinguishing agent 220' is ejected. The air passage 132' is communicated with the installation hole 131' to ensure that the gas ejected from the head 211' of the sealed container 21' can enter the air passage 132'; one end of the air passage 132' penetrates the housing 1' to ensure that the After the body 1' is assembled with the fire extinguishing agent storage container 210', the air passage 132' can communicate with the fire extinguishing agent storage container 210'.

In an illustrative example, further, as shown in FIG. 4 , the housing 1' includes a housing 11' and a support seat 13'. A second installation cavity 112' is provided in the housing 11'. The support base 13' is installed in the second installation cavity 112'. A mounting hole 131' and an air passage 132' are provided on the support base 13'.

Splitting the shell 1' into multiple parts such as the shell 11' and the support seat 13' 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 internal components of the shell 1'. Therefore, the structure of the starting device 100' is optimized, and the assembly difficulty of the starting device 100' is reduced.

In a schematic example, further, 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 portion 312' is inserted into the escape hole 133', as shown in FIG. 4 . The cross-sectional area of the avoidance hole 133' is larger than that of the mounting hole 131'. The air passage 132' penetrates both ends of the support base 13' along the axial direction of the escape hole 133', and the air passage 132' penetrates the hole wall of the escape hole 133' along the radial direction of the escape hole 133'.

In this embodiment, the arrangement of the avoidance hole 133' reduces the distance between the striker 31' and the sealed container 21', so that the striker 31' can quickly pierce the sealed container 21'. At the same time, the avoidance hole 133' is relatively thick, and the installation hole 131' is relatively thin, so that the air passage 132' can penetrate the hole wall of the avoidance hole 133' along the radial direction of the avoidance hole 133', so that the hole wall of the avoidance hole 133' can be It is not a complete annular structure in the circumferential direction, but the hole wall of the mounting hole 131 ′ may be a complete annular structure in the circumferential direction. In this way, the mounting hole 131' and the head 211' of the sealed container 21' can have a larger contact area, so as to improve the fixing reliability of the sealed container 21'; and the gas ejected from the head 211' in the mounting hole 131' Access to the gas passage 132' can be made easier, thereby increasing the initiation speed of the initiation device 3'.

Further, the cross section of the escape hole 133' is circular. The cross section of the mounting hole 131' is circular. The avoidance hole 133' is coaxial with the installation hole 131', and the radius of the avoidance hole 133' is larger than the radius of the installation hole 131'.

Further, the support base 13' is connected with the outer shell 11' by screw thread, the connection is reliable, and the assembly is convenient. The head 211' of the sealed container 21' is screwed with the support base 13', the connection is reliable, and the assembly is convenient.

Further, the number of air passages 132' is multiple, and the plurality of air passages 132' are arranged at intervals along the circumferential direction of the support base 13', which facilitates the rapid and uniform entry of gas into the fire extinguishing agent storage container 210'.

In an illustrative example, further, as shown in FIG. 4 , the cross-sectional area of the second installation cavity 112 ′ is larger than that of the first installation cavity 111 ′, so that the first installation cavity 111 ′ and the second installation cavity 111 ′ have a cross-sectional area The cavity 112' forms a stepped hole structure. The end face of the support base 13' close to the first installation cavity 111' abuts against the end face of the second installation cavity 112'. The end surface of the support base 13' close to the first installation cavity 111' protrudes out of the inner side 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 inserted into the first installation cavity 111' through the second installation cavity 112' first, and then the striker 31' can be inserted into the first installation cavity 111' through the second installation cavity 112' , and then put the support base 13' into the second installation cavity 112' until the support base 13' abuts against the steps of the stepped hole, and then put the head 211' of the sealed container 21' into the support base 13' for installation inside the hole 131'. In this way, the assembling process of the activation device 100' is simple and convenient.

In addition, during use, when the striker 31' moves to abut against the support base 13', it will be stopped by the support base 13' and cannot continue to move, thereby limiting the sliding stroke of the striker 31' and preventing the striker 31' from moving. Excessive movement range causes the sealed container 21' to deform excessively and fall off.

Further, the needle-piercing portion 312' of the striker 31' is provided with a transition channel 3121' connected to the air channel 132', as shown in FIG. 4 . In this way, the gas in the sealed container 21' can also enter the gas passage 132' through the transition channel 3121', thereby further improving 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 on the initiator 32' can be further reduced.

In a schematic example, further, as shown in FIG. 4 , the housing 1' is provided with at least one ejection channel 116', and the ejection channel 116' communicates with the ejection port 115'. The starting device 100' further includes a sealing valve 4', which is used for disconnecting the communication between the ejection channel 116' and the nozzle 115', and the sealing valve 4' is arranged to lead under the impact of the fluid (such as the fire extinguishing agent 220'). Through the ejection channel 116' and the nozzle 115'.

The ejection channel 116' is configured to communicate with the fire suppressant storage container 210'. The sealing valve 4' ensures that the discharge channel 116' and the nozzle 115' of the fire extinguishing device are in a disconnected state when the fire extinguishing device is not in use, thereby preventing the fire extinguishing agent 220' from being sprayed and causing property damage or personal injury. In the event of a fire, when the initiating device 3 ′ opens the sealed container 21 ′, the fire extinguishing agent in the fire extinguishing agent storage container 210 ′ flows to the ejection channel 116 ′ under the action of air pressure, and then the sealing valve 4 is opened. ', the fire is ejected from the nozzle 115'. Of course, when the activation device 100' is used in other equipment, the ejection channel 116' is arranged to be able to communicate with the container body of the other equipment.

Wherein, the sealing valve 4' can use a metal sealing plug, which is an interference fit with the housing 1'.

Further, at least one sealing ring is sleeved between the sealing valve 4' and the housing 1', so as to further improve the sealing reliability of the sealing valve 4'. The outer side wall of the sealing valve 4' is provided with a sealing groove 3113' for installing the sealing ring.

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

The number of the ejection channels 116' may also be different from the number of the ejection ports 115'. For example, the ejection channels 116' can be of a three-way structure, a four-way structure, etc., and one ejection channel 116' can be connected to three or four ejection ports. 115', which is beneficial to reduce the number of sealing valves 4', thereby simplifying the product structure and reducing the product cost.

In a schematic example, further, as shown in FIG. 4 , the starting device 100' further includes: a siphon 5', which is fixedly connected to the housing 1' and communicates with the ejection channel 116'.

After the activation device 100' is assembled with the fire extinguishing agent storage container 210', the siphon 5' is inserted into the fire extinguishing agent storage container 210'. The siphon 5' can utilize the siphon principle to suck the extinguishing agent 220' in the extinguishing agent storage container 210' into the ejection channel 116', so that the extinguishing agent 220' continuously enters the ejection channel 116', thereby improving the extinguishing efficiency. Further, the siphon tube 5' is a plastic tube, and the siphon tube 5' is screwed to the housing 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, for the case where 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 ejection channel 116' under the action of gravity, and the siphon 5' can also be eliminated in this case.

In a schematic example, further, 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 cavity 113' to disconnect the communication between the ejection channel 116' and the nozzle 115', and is set to be able to move to the avoidance cavity 117' under the impact of the fluid (such as the fire extinguishing agent 220'). Inside, the discharge channel 116' and the nozzle 115' are connected.

In this way, after the sealing valve 4' is impacted by the fire extinguishing agent 220', it is still located in the casing 1', which can prevent the sealing valve 4' from collapsing and causing property damage or being covered by a person.

In a schematic example, further, as shown in FIG. 4 , the activation device 100 ′ further includes: an elastic member 6 ′, which is arranged in the housing 1 ′ and abuts against the sealing valve 4 ′ for restricting the sealing valve 4' moves towards the escape cavity 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 being accidentally ejected when there is no fire, resulting in property damage or personal injury.

Wherein, the elastic member 6' can be a compression spring, a shrapnel, a silicone ball or the like.

In an illustrative example, further, 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' which is open at both ends. One end of the fourth installation cavity 114' communicates with the third installation cavity 113', and the sealing cover 14' is used to cover one end of the fourth installation cavity 114' away from the third installation cavity 113'.

Splitting the casing 1' into multiple components such as the casing 11' and the sealing cover 14' 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 needs, and also facilitates the internal components of the casing 1'. Therefore, the structure of the starting device 100' is optimized, and the assembly difficulty of the starting device 100' is reduced.

Specifically, during the assembly process, the sealing valve 4' can be installed into the third installation cavity 113' through the fourth installation cavity 114' first, and then the elastic member 6' can be installed into the housing 11', so that the elastic member 6' can be installed into the housing 11'. Abut against the sealing valve 4', and then cover the sealing cover 14'.

Further, 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 groove 141' can limit the position of the elastic member 6' to prevent the elastic member 6' from being tilted, displaced, etc., thereby improving the reliability of the elastic member 6'.

In an illustrative example, further, as shown in FIG. 4 , the 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 being tilted, displaced, etc., and ensures the good cooperation between the elastic member 6' and the sealing valve 4'.

Further, as shown in Fig. 4, the end of the sealing valve 4' facing the sealing cover 14' is also 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 cavity 113', which can prevent the sealing valve 4' from being stuck in the third installation cavity 113' and affect the normal ejection of the fire extinguishing agent 220'.
