Description
Starting Apparatus and Fire Extinguishing Device
Technical Field
Embodiments of the present application relate to, but are not limited to, the technical field of fire extinguishing device, and more particularly relate to a starting apparatus and a fire extinguishing device.
Background
In order to spray out the fire extinguishing agent to extinguish the fire, the pressure-storage type fire extinguishing device needs to fill a container with a certain amount of pressurized gas, and a pressure of the gas generally ranges from 1.2 MPa to 20MPa. The whole fire extinguishing device is composed of many components, such as a fire extinguishing agent storage container, a container valve (head valve), a pressure gauge, a fire extinguishing agent spray port, a signal feedback apparatus. In addition, the pressure-storage typefire extinguishing device is stored with pressurization for a long time. Therefore, the connections between these components become pressure leakage points. Once there is pressure leakage from the fire extinguishing device, the fire extinguishing agent cannot be sprayed out normally. Therefore, pressure-storage type fire extinguishing device needs regular maintenance and pressurization. If the maintenance is not timely, once a fire event happens at this time, in particular in public transportation, it is necessary to drive to a station for maintenance and pressurization. If the pressure is leaked during driving and the fire cannot be extinguished, it will lead to mass casualties and serious consequences.

As shown in FIG. 1, an embodiment of the present application provides a starting apparatus 100. The starting apparatus 100 includes a housing 1, a gas generation apparatus 2 and an initiation apparatus 3.
The gas generation apparatus 2 includes an integrated sealing container 21 and a driving medium 22 sealed in the sealing container 21, and the sealing container 21 is connected to the housing 1. The initiation apparatus 3 is cooperated with the gas generation apparatus 2 for opening the sealing container 21, so that the driving medium 22 is sprayed out of the sealing container 21 and forms a gas.
According to the starting apparatus 100 provided in the embodiment of the present application, the driving medium 22 is encapsulated in the integrated sealing container 21, and when fire extinguishing is required, the sealing container 21 can be opened by the initiation apparatus 3, so that the driving medium 22 is sprayed out of the sealing container 21 and forms a gas capable of driving the fire extinguishing agent 220 to be sprayed out. The gas can enter the fire extinguishing agent storage container 210 to rapidly pressurize the fire extinguishing agent storage container 210, thereby enabling the fire extinguishing agent 220 to be sprayed out under the action of pressure so as to extinguish fire. Thus, the fire extinguishing agent 220 does not need to be stored under pressure, thereby fundamentally solving the problem of pressure leakage of the existing pressure-storage type fire extinguishing device, eliminating the maintenance cost of periodic pressure charging and improving the operational reliability of the fire extinguishing device 200.
Specifically, the starting apparatus 100 includes a housing 1, a gas generation apparatus 2 and an initiation apparatus 3. The gas generation apparatus 2 is a non-pyrotechnic product, and specifically includes a sealing container 21 and a driving medium 22. The sealing container 21 has an integral structure and the driving medium 22 is stored in the sealing container 21. When a fire needs to be extinguished, the sealing container 21 can be opened by the initiation apparatus 3. When the sealing container 21 is opened, the pressure can be quickly released, so that the driving medium 22 is sprayed out in the form of gas, thereby rapidly increasing the air pressure in the fire extinguishing agent storage container 210 and driving the fire extinguishing 5 20570415_1 (GHMatters) P123715.AU agent 220 to be sprayed out to extinguish the fire.
Thus, the fire extinguishing agent 220 does not need to be stored under pressure, and
when in use, it only needs to be rapidly pressurized by the gas generation apparatus 2 before
being sprayed out, thereby solving the problem that the fire extinguishing device 200 cannot
normally spray the fire extinguishing agent 220 due to pressure leakage of the existing
pressure-storage type fire extinguishing device, saving the maintenance cost of regular pressure
charging, and saving the pressure gauge.
Moreover, the sealing container 21 of the gas generation apparatus 2 is an integrated
structure, which is a sealed single piece and a complete component. It can be stored
independently without a sealing ring, a sealant, a sealing cover, a sealing bolt and the like, so
that there is no pressure leakage problem, and the driving medium 22 can be stably sealed in the
sealing container 21 without leakage. A shape of the sealing container 21 is not limited, for
example, a cross section of the sealing container 21 may be circular, oval, rectangular, square,
triangular, or the like. The sealing container 21 may be a metal container.
An amount of the gas sprayed by the gas generation apparatus 2 may be variable, and the
spraying time may be variable, which may be reasonably selected according to an amount of the
driving medium 22.
In addition, in an existing non-pressure-storage type fire extinguishing device, the
initiation apparatus 3 is placed inside the gas generation apparatus 2, and the gas generation
apparatus 2 is initiated to spray out gas by electric initiation or thermal initiation. Since the gas
generation apparatus used in the existing non-pressure-storage type fire extinguishing device is
a pyrotechnic product, when the initiation apparatus initiates the gas generation apparatus, a
high temperature of hundreds of degrees Celsius will be instantly generated. Gas will explode
when exposed to high temperature, so it cannot be used in gas fire extinguishing device, but can
only be used in dry powder fire extinguishing device. According to the starting apparatus 100
provided in the present scheme, the initiation apparatus 3 is provided outside the gas generation
apparatus 2, the gas generation apparatus 2 is a non-pyrotechnic product, and the gas generation
apparatus 2 is initiated to generate a gas by opening the sealing container 21 to relieve the
pressure of the sealing container 21, so that it can be applied not only to dry powder fire
6 20570415_1 (GHMatters) P123715.AU extinguishing apparatus, but also to gas fire extinguishing apparatus and liquid fire extinguishing apparatus, thus greatly expanding the scope of non-pressure-storage type fire extinguishing device and solving the pressure relief problem existing in the field of pressure-storage type fire extinguishing device for many years.
In addition, compared with the existing non-pressure-storage type dry powder fire
extinguishing device, by adopting the starting apparatus 100 of the present scheme, the
explosion of dry powder caused by improper initiation due to ignition may be avoided, thus
avoiding the potential safety hazard caused by the explosion of the fire extinguishing device
200 itself. Compared with the existing pressure-storage type gas fire extinguishing device, by
adopting the starting apparatus 100 of the present scheme, the pressure-storage type gas fire
extinguishing device can be converted into a non-pressure-storage type gas fire extinguishing
device, thus fundamentally solving the pressure leakage problem of the gas fire extinguishing
device and improving the fire extinguishing reliability of the gas fire extinguishing device.
Apparently, the starting apparatus provided by the embodiment of the present application
can not only be used for fire extinguishing device, but also be widely applied to pressurized
devices (with pressurized containers) in various fields of national economy such as energy,
transportation, metallurgy, electric power, communication, and the like. The existing
pressurized devices can be converted into non-pressure-storage devices, thereby solving the
pressure relief problem that has plagued the industry for many years and providing effective
guarantee for protecting the safety of national property and people.
When the starting apparatus is used for other devices, correspondingly, a spout 115 is
used for spraying out a material in the other pressurized container, and the driving medium 22
in the gas generation apparatus 2 is sprayed out of the sealing container 21 and forms a gas for
driving the material in the container of the other device to be sprayed out.
In an illustrative example, as shown in FIG. 1, the initiation apparatus 3 includes a striker
31 and a trigger 32. The striker 31 is provided corresponding to the sealing container 21 and
configured to pierce the sealing container 21 so as to open the sealing container 21. The trigger
32 cooperates with at least one of the gas generation apparatus 2 and the striker 31 and is
configured to drive the at least one of the gas generation apparatus 2 and the striker 31 to move
7 20570415_1 (GHMatters) P123715.AU in a direction approaching the other of the gas generation apparatus 2 and the striker 31, so that the striker 31 pierces the sealing container 21.
In this example, the initiation apparatus 3 includes a striker 31 and a trigger 32. The
trigger 32 may be used to drive the striker 31 to move, so that the striker 31 approaches and
pierces the sealing container 21. Alternatively, the trigger 32 may also be used to drive the gas
generation apparatus 2 to move, so that the gas generation apparatus 2 approaches the striker 31,
thereby enabling the striker 31 to pierce the sealing container 21. Alternatively, the trigger 32
may also be used to drive both the striker 31 and the gas generation apparatus 2 to move, so that
the gas generation apparatus 2 and the striker 31 approach each other until the striker 31 pierces
the sealing container 21, which is beneficial to improving the initiation speed. As long as the
striker 31 and the sealing container 21 approach each other gradually, the striker 31 can quickly
pierce the sealing container 21 by using a tip portion thereof without generating sparks, thus
being safe to use and having high opening efficiency.
Apparently, the initiation apparatus 3 is not limited to the above schemes. For example,
the initiation apparatus may also include a cutter and a motor, and the motor drives the cutter to
move, so that the cutter cuts the sealing container and the sealing container is opened.
Alternatively, the initiation apparatus may also include a small electric drill by which the
sealing container is opened.
In an illustrative example, as shown in FIG. 1, the gas generation apparatus 2 is located in
the housing 1. The striker 31 is fixed in the housing 1, and the trigger 32 cooperates with the
gas generation apparatus 2 for driving the gas generation apparatus 2 to move in a direction
approaching the striker 31. The gas generation apparatus 2 is located in the housing 1, and may
be protected by the housing 1 to prevent the gas generation apparatus 2 from being mistakenly
opened by other structure(s) outside the housing 1 and causing the fire extinguishing device 200
to be opened accidentally, and resulting in property loss or personal injury.
In an illustrative example, as shown in FIG. 1, the housing 1 includes a first outer shell 11
and a support seat 12, and the support seat 12 is in contact and cooperation with the gas
generation apparatus 2. Both the support seat 12 and the gas generation apparatus 2 are in
sliding cooperation with the first outer shell 11. The support seat 12 is located in the first outer
8 20570415_1 (GHMatters) P123715.AU shell 11, and the support seat 12 and the first outer shell 11 enclose a sealed cavity 13. One end of the trigger 32 is located in the sealed cavity 13 and configured to raise an air pressure in the sealed cavity 13 to drive the support seat 12 so as to drive the gas generation apparatus 2 to move in a direction approaching the striker 31. The other end of the trigger 32 extends through the first outer shell 11 to outside the first outer shell 11.
The housing 1 is split into a plurality of components such as the first outer shell 11 and the support seat 12, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to the need, and facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100.
In an example, the first outer shell 11 and the support seat 12 enclose a sealed cavity 13. The trigger 32 is specifically used to raise the air pressure in the sealed cavity 13, and then the support seat 12 is driven to move by the raised air pressure. Since the support seat 12 is in contact and cooperation with the gas generation apparatus 2, the support seat 12 may drive the gas generation apparatus 2 to move, thus realizing the driving function of the trigger 32 to the gas generation apparatus 2, which is an ingenious idea. The support seat 12 drives the gas generation apparatus 2 to move so that the gas generation apparatus 2 is separated from the sealed cavity 13, which may prevent the temperature change in the sealed cavity 13 from causing the temperature change of the sealing container 21 and affecting the state of the driving medium in the sealing container 21, thereby improving the stability of the gas generation apparatus 2.
In an example, as shown in FIG. 1, the support seat 12 is provided with an avoidance groove 122, which may avoid the resistor 321 of an electrical trigger and prevent the resistor 321 from being damaged during assembly due to insufficient space of the sealed cavity 13.
In an illustrative example, as shown in FIG. 2, the sealing container 21 includes a head 211 and a body 212. The head 211 is provided corresponding to the striker 31. The support seat 12 is provided with a limiting groove 121, and an end of the body 212 away from the head 211 is in a concave-convex cooperation with the limiting groove 121.
The head 211 of the sealing container 21 is provided corresponding to the striker 31 and 9 20570415_1 (GHMatters) P123715.AU may be pierced by the striker 31 so that the sealing container 21 is opened. The limiting groove
121 of the support seat 12 may limit the sealing container 21 and increase a contact area
between the support seat 12 and the sealing container 21, thereby improving the stability of the
gas generation apparatus 2 during movement and reducing the probability of inclination,
displacement and the like of the gas generation apparatus 2.
In an illustrative example, the trigger 32 includes an electrical trigger 32. As shown in
FIG. 1, the electrical trigger 32 includes a resistor 321 and a connecting wire 322 connected to
the resistor 321, the resistor 321 is located within the sealed cavity 13 and the connecting wire
322 extends through the housing 1 to outside the housing 1.
In another illustrative example (not shown in the figures), the trigger 32 includes a
thermal trigger 32.
In yet another illustrative example (not shown in the figures), the trigger 32 includes both
the electrical trigger 32 as described above and the thermal trigger 32 as described above.
The trigger 32 may be an electrical trigger 32. By connecting to a power supply, the
resistor 321 generates heat, so that the air pressure in the sealed cavity 13 is raised, which in
turn causes the support seat 12 and the gas generation apparatus 2 to move, so that the striker 31
opens the sealing container 21. The electrical trigger 32 has three indexes: starting current,
safety current and resistance value. These three indexes meet the following relationships: the
safety current is less than the starting current, and within the safety current index, the resistor
321 shall not generate heat within five minutes after power-on; when the current reaches or
exceeds the starting current, the resistor 321 generates heat; the smaller the resistance value, the
greater the current, and on the contrary, the greater the resistance value, the smaller the current;
and all of the safety current, the starting current and the resistance value may be set as required.
The trigger 32 may also be a thermal trigger 32. The thermal trigger 32 includes a thermal
sensitive element, which is sensitive to the outside temperature. When a fire occurs, the thermal
sensitive element may sense the rise of the outside temperature and generate heat, causing the
air pressure in the sealed cavity 13 to be raised, which then automatically initiates the support
seat 12 and the sealing container 21 to move, so that the striker 31 opens the sealing container
21. 10 20570415_1 (GHMatters) P123715.AU
Apparently, the trigger 32 may also include both the electrical trigger 32 and the thermal
trigger 32, so that the fire extinguishing device may be initiated manually or automatically,
effectively preventing the risk caused by the failed initiation of thefire extinguishing device.
In an illustrative example, as shown in FIG. 1, the first outer shell 11 includes a shell body
111 and a first cover 112. The shell body 111 is provided with a first mounting opening 1111.
At least a part of the gas generation apparatus 2 is located within the shell body 111 and is in
sliding cooperation with the shell body 111. The support seat 12 is mounted at the first
mounting opening 1111 and is in sliding cooperation with the shell body 111. The first cover
112 is connected to the shell body 111, and a space between the first cover 112 and the support
seat 12 forms the sealed cavity 13.
The first outer shell 11 is split into a plurality of components such as the shell body 111
and the first cover 112, which is beneficial to reducing the processing difficulty of each
component, reasonably selecting the material of each component according to the need, and
facilitating the assembly of the components inside the housing 1, thereby optimizing the
structure of the starting apparatus 100 and reducing the assembly difficulty of the starting
apparatus 100. In the assembly process, the gas generation apparatus 2 may be first mounted
into the shell body 111 through the first mounting opening 1111, then the support seat 12 is
mounted at the first mounting opening 1111, and then the first cover 112 is mounted. The first
cover 112 may be threadedly connected and fixed to the shell body 111, so as to realize
high-strength connection and convenient and quick assembly.
In an illustrative example, as shown in FIG. 1, the shell body 111 has a cylindrical
structure. The first mounting opening 1111is provided at one end of the shell body 111, and a
second mounting opening 1112 is provided at the other end of the shell body 111. The gas
generation apparatus 2 is located in the shell body 111. The first outer shell 11 further includes
a sealing assembly 113 that seals the second mounting opening 1112. A striker 31 is located
between the sealing assembly 113 and the gas generation apparatus 2. The sealing assembly
113 is provided with a gas channel 1135. The gas channel 1135 is communicated with an
internal space of the shell body 111 and is used for delivering a gas sprayed out of the sealing
container 21, specifically for delivering a gas for driving the fire extinguishing agent 220 to be
11 20570415_1(G HMatters) P123715.AU sprayed out into the fire extinguishing agent storage container 210.
Since the shell body 111 has a cylindrical structure and is provided to open at both ends,
the first mounting opening 1111 and the second mounting opening 1112 are respectively
formed at two ends of the shell body 111, which has a simple structure and facilitates
processing and shaping. The gas generation apparatus 2 is completely provided in the shell
body 111, and two ends of the shell body 111 are respectively covered by the support seat 12
and the sealing assembly 113, so that the gas generation apparatus 2 may be well protected and
the fire extinguishing device 200 may be effectively prevented from being mistakenly opened
due to the mistaken opening of the gas generation apparatus 2. Accordingly, the gas channel
1135 is provided on the sealing assembly 113, which ensures that the gas sprayed out of the gas
generation apparatus 2 can be sprayed out of the housing 1 through the gas channel 1135 and
then delivered into the fire extinguishing agent storage container 210, thereby rapidly
increasing the air pressure in the fire extinguishing agent storage container 210 to drive the fire
extinguishing agent 220 to be sprayed out.
The shell body 111 may have a cylindrical structure. Accordingly, a cross section of the
sealing container 21 may be circular. Thus, there is no rib, corner or other structures between
the sealing container 21 and the shell body 111, which is beneficial to reducing the probability
of sticking between the sealing container 21 and the shell body 111, thereby improving the
operational reliability of the starting apparatus 100. The striker 31 may be fixed in the shell
body 111 by a bracket.
Apparently, when the starting apparatus is used for other devices, the gas channel is used
for delivering a gas formed by the driving medium (i.e., a gas sprayed out of the sealing
container) to container bodies of other devices.
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 to the shell body 111. The second cover 1131 is provided with a first
avoidance notch 1134. The sealing plug 1132 is located within the shell body 111 and in
interference cooperation with the shell body 111. The gas channel 1135 is provided on the
sealing plug 1132 and is provided corresponding to the first avoidance notch 1134. The striker
12 20570415_1 (GHMatters) P123715.AU
31 is located between the gas generation apparatus 2 and the sealing plug 1132. The first sealing diaphragm 1133 is sandwiched between an end face of the shell body 111 and the second cover 1131.
The sealing plug 1132 is in interference cooperation with the shell body 111, which improves the sealing reliability. The sealing plug 1132 is provided with a gas channel 1135 to ensure that the gas sprayed out of the gas generation apparatus 2 can be sprayed out of the housing 1. The first sealing diaphragm 1133 plays a blocking role for the gas channel 1135 to ensure that the gas channel 1135 does not communicate with thefire extinguishing agent storage container 210 when there is no fire. When a fire occurs, after the gas generation apparatus 2 is opened, the gas passing through the gas channel 1135 may burst the first sealing diaphragm 1133, and then enter the fire extinguishing agent storage container 210, causing the air pressure in the fire extinguishing agent storage container 210 to rapidly increase, thereby driving the fire extinguishing agent 220 to be sprayed out. The second cover 1131 plays a role in fixing the sealing plug 1132 and the first sealing diaphragm 1133 to ensure stability of the sealing plug 1132 and the first sealing diaphragm 1133.
The first sealing diaphragm 1133 may be made of aluminum or other materials. The second cover 1131 may be threadedly connected to the shell body 111 so that the connection strength is high and the assembly is convenient and quick. The sealing plug 1132 may be a silicone plug or a rubber plug. The striker 31 is fixedly connected to the sealing plug 1132, and the fixed connection may be realized by means of interference cooperation, insert molding and the like.
In an example, the driving medium 22 is a gaseous medium. The driving medium 22 may be a gaseous medium stored in the sealing container 21, which is rapidly sprayed out when the sealing container 21 is opened. The driving medium 22 may be a medium such as nitrogen, argon, carbon dioxide, air and the like, and a pressure level is higher than 1.2 MPa.
In another example, the driving medium 22 is a liquid medium. The driving medium 22 may also be a liquid medium, which may be encapsulated in the sealing container 21 in a liquid form. After the sealing container 21 is opened, the liquid medium is vaporized into a gas such as liquid carbon dioxide, liquid propane and the like, to be sprayed out. In other words, the 13 20570415_1 (GHMatters) P123715.AU driving medium 22 is a liquid-to-gaseous medium.
Alternatively, the driving medium 22 may also be a solid medium, which is encapsulated in the sealing container 21 in a solid state. After the sealing container 21 is opened, the solid medium is sublimated into a gas, such as solid carbon dioxide (dry ice) and the like, to be sprayed out. In other words, the driving medium 22 is a solid-to-gaseous medium, which is directly changed into a gaseous state through pressure relief in the sealing container, instead of generating gas through combustion or explosion. Therefore, the gas generation apparatus 2 is still a non-pyrotechnic product.
Alternatively, the driving medium includes any combination of a gaseous medium, a liquid medium, and a solid medium. In other words, the driving medium may also include a gaseous medium and a liquid medium. Alternatively, the driving medium may also include a gaseous medium and a solid medium. Alternatively, the driving medium may also include a liquid medium and a solid medium. Alternatively, the driving medium may also include a gaseous medium, a liquid medium and a solid medium. The premise is that two or three media in different states sealed in the sealing container do not react with each other and can be sprayed out in a gaseous form after the sealing container is opened.
In an example, a Rockwell hardness of the striker 31 is greater than or equal to HR60. The hardness of the striker 31 within the above range may ensure that the striker 31 can pierce the sealing container 21 quickly and effectively.
In an example, a diameter of a tip of the striker 31 is between 2mm and 3mm. The diameter of the tip of the striker 31 being limited between 2mm and 3mm may ensure that the gas can be quickly sprayed out after the sealing container 21 is pierced.
As shown in FIG. 4, another embodiment of the present application provides a starting apparatus 100. The starting apparatus 100 includes a housing 1, a gas generation apparatus 2 and an initiation apparatus 3.
The housing 1 is provided with at least one spout 115. The gas generation apparatus 2 includes an integrated sealing container 21 and a driving medium 22 sealed in the sealing
14 20570415_1 (GHMatters) P123715.AU container 21. The sealing container 21 is connected to the housing 1. The initiation apparatus 3 is located outside the gas generation apparatus 2. The initiation apparatus 3 includes a striker 31 and a trigger 32. The striker 31 is provided corresponding to the sealing container 21 and configured to pierce the sealing container 21 so that the driving medium 22 is sprayed out of the sealing container 21 and forms a gas. The trigger 32 cooperates with the striker 31 and is configured for driving the striker 31 to move in a direction approaching the sealing container 21, so that the striker 31 pierces the sealing container 21.
In other words, this embodiment differs from the foregoing first embodiment (as shown in
FIGS. 1 and 2) in that: the housing 1 is provided with at least one spout 115. The initiation
apparatus 3 includes a striker 31 and a trigger 32. The striker 31 is provided corresponding to
the sealing container 21 and configured to pierce the sealing container 21 so that the driving
medium 22 is sprayed out of the sealing container 21 and forms a gas. The trigger 32 cooperates
with the striker 31 and is configured for driving the striker 31 to move in a direction
approaching the sealing container 21, so that the striker 31 pierces the sealing container 21.
In this embodiment, the trigger 32 is used to drive the striker 31 to move. The striker 31
can quickly pierce the sealing container 21 by a tip portion thereof without generating sparks,
thus being safe to use and having high opening efficiency.
The housing 1 is provided with at least one spout 115. The spout 115 is configured 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 may be sprayed
out at least through the spout 115 of the starting apparatus 100. A quantity of the spout 115 may
be one or a plurality, and a plurality of spouts 115 is advantageous for improving the fire
extinguishing efficiency.
In an illustrative example, as shown in FIG. 4, the striker 31 is located within the housing
1, and the striker 31 and the housing 1 enclose a sealed cavity 1111. One end of the trigger 32 is
located in the sealed cavity 1111 and configured to raise an air pressure in the sealed cavity
1111 to drive the striker 31 to move in the direction approaching the sealing container 21. The
other end of the trigger 32 extends through the housing 1 to outside the housing 1.
In this embodiment, the trigger 32 is specifically used to raise the air pressure in the 15 20570415_1 (GHMatters) P123715.AU sealed cavity 1111, and then the striker 31 is driven to move by the raised air pressure, which is an ingenious idea.
In an example, the trigger 32 includes an electrical trigger 32. As shown in FIG. 4, the electrical trigger 32 includes a resistor 321 and a connecting wire 322 connected to the resistor 321, the resistor 321 is located within the sealed cavity 13 and the connecting wire 322 extends through the housing 1 to outside the housing 1. Apparently, the trigger 32 may also include a thermal trigger 32, or the trigger 32 may include both the electrical trigger 32 as described above and the thermal trigger 32 as described above.
In an illustrative example, as shown in FIG. 4, the striker 31 includes a sliding portion 311 and a needle portion 312. The sliding portion 311 and the housing 1 enclose the sealed cavity 1111, and the sliding portion 311 is in sliding cooperation with the housing 1. The needle portion 312 is connected to the sliding portion 311 and is provided toward the sealing container 21 and configured for piercing the sealing container 21.
The striker 31 includes the sliding portion 311 and the needle portion 312, and the sliding portion 311 is in sliding cooperation with the housing 1, it is ensured that the striker 31 may smoothly move relative to the housing 1. The needle portion 312 is provided corresponding to the sealing container 21 for realizing the pierce function of the striker 31.
An outer wall of the sliding portion 311 may have a cylindrical structure, so that there is no rib, comer or other structure between the sliding portion 311 and the housing 1, which is beneficial to reducing the probability of sticking between the striker 31 and the housing 1, thereby improving the reliability of the starting apparatus 100 in use. The needle portion 312 may include a conical structure, which has both a high strength and a tip portion.
In an illustrative example, as shown in FIG. 4, the sliding portion 311 includes an end plate 3111 and a side wall plate 3112. The side wall plate 3112 is connected to an edge of the end plate 3111, and the side wall plate 3112 and the end plate 3111 enclose a groove having an opening end. The housing 1 seals the opening end of the groove, and the housing 1 and the sliding portion 311 enclose the sealed cavity 1111. The needle portion 312 is connected to a plate surface of the end plate 3111 facing away from the side wall plate 3112.
In this scheme, the sliding portion 311 has a hollow structure, and the sealed cavity 111 16 20570415_1 (GHMatters) P123715.AU is enclosed by the sliding portion 311 and the housing 1, which, on one hand, is beneficial to reducing a volume of the sealed cavity 1111, thereby improving the rising speed of the air pressure in the sealed cavity 1111, and on the other hand, is beneficial to reducing a mass of the striker 31, thereby reducing the air pressure value for pushing the striker 31 to move, thus increasing the initiation speed of the initiation apparatus 3.
In an example, the end plate 3111, the side wall plate 3112, and the needle portion 312 form an integrated structure, i.e., the striker 31 is integrally formed, so that the striker 31 has high strength, which is beneficial to improving assembly efficiency.
In an illustrative example, as shown in FIG. 4, the housing 1 includes an outer shell 11 and a sealing plug 12. A first mounting cavity 111 is provided in the outer shell 11. The sealing plug 12 and at least a part of the striker 31 are located in thefirst mounting cavity 111. The sliding portion 311 is in sliding cooperation with the outer shell 11. The sealing plug 12 and the sliding portion 311 enclose a sealed cavity 1111.
The housing 1 is split into a plurality of components such as the outer shell 11, the sealing plug 12, and the like, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to the need, and facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100. The sealing plug 12 is used to seal the groove of the sliding portion 311, which is beneficial to improving the sealing reliability of the sealed cavity 1111. The outer shell 11 may be a metal shell. The sealing plug 12 may be a rubber plug or a silicone plug.
In an illustrative example, the striker 31 may be made of metal and has a high hardness so as to pierce the sealing container 21 rapidly. At least one sealing ring is provided between the sliding portion 311 and the outer shell 11 to further improve the sealing reliability of the sealed cavity 1111. The side wall plate 3112 of the sliding portion 311 is provided with at least one sealing groove 3113 for mounting the sealing ring, as shown in FIG. 4. The outer shell 11 is provided with a through hole, and the trigger 32 extends to the outside of the housing 1 through the sealing plug 12 and the through hole.
In an illustrative example, as shown in FIG. 4, the housing 1 is provided with a mounting 17 20570415_1 (GHMatters) P123715.AU hole 131 and at least one gas channel 132. The sealing container 21 includes a head 211 and a body 212, as shown in FIG. 5. The head 211 is mounted in the mounting hole 131 and is provided corresponding to the striker 31 for spraying out the gas formed by the driving medium 22. The gas channel 132 is communicated with the mounting hole 131 and one end of the gas channel 132 penetrates the housing 1 for delivering the gas formed by the driving medium 22 into the fire extinguishing agent storage container 210.
The housing 1 is provided with a mounting hole 131 and a gas channel 132. The mounting hole 131 is used for mounting the head 211 of the sealing container 21, and the body 212 of the sealing container 21 may be inserted into the fire extinguishing agent storage container 210. The gas channel 132 is used for delivering a gas to thefire extinguishing agent storage container 210 so as to rapidly pressurize the fire extinguishing agent storage container 210 and then spray out the fire extinguishing agent 220. The gas channel 132 is communicated with the mounting hole 131 to ensure that the gas sprayed out of the head 211 of the sealing container 21 can enter the gas channel 132. One end of the gas channel 132 penetrates the housing 1 to ensure that the gas channel 132 can communicate with the fire extinguishing agent storage container 210 after the housing 1 is assembled with the fire extinguishing agent storage container 210.
In an illustrative example, as shown in FIG. 4, the housing 1 includes an outer shell 11 and a support seat 13. A second mounting cavity 112 is provided in the outer shell 11. The support seat 13 is mounted in the second mounting cavity 112. The mounting hole 131 and the gas channel 132 are provided on the support seat 13.
The housing 1 is split into a plurality of components such as the outer shell 11, the support seat 13, and the like, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to the need, and facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100.
In an illustrative example, the support seat 13 is further provided with an avoidance hole 133 which is communicated with the mounting hole 131. The needle portion 312 is inserted into 18 20570415_1 (GHMatters) P123715.AU the avoidance hole 133, as shown in FIG. 4. A cross-sectional area of the avoidance hole 133 is greater than a cross-sectional area of the mounting hole 131. The gas channel 132 penetrates two ends of the support seat 13 along an axial direction of the avoidance hole 133, and the gas channel 132 penetrates a hole wall of the avoidance hole 133 along a radial direction of the avoidance hole 133.
In this embodiment, by providing the avoidance hole 133, a distance between the striker 31 and the sealing container 21 is reduced, facilitating the striker 31 to pierce the sealing container 21 quickly. Meanwhile, the avoidance hole 133 is relatively greater in diameter and the mounting hole 131 is relatively less in diameter, so that the gas channel 132 can penetrate a hole wall of the avoidance hole 133 in a radial direction of the avoidance hole 133, and the hole wall of the avoidance hole 133 is not a complete annular structure in a circumferential direction, while the hole wall of the mounting hole 131 may be a complete annular structure in the circumferential direction. Thus, the mounting hole 131 and the head 211 of the sealing container 21 may have a greater contact area to improve the fixing reliability of the sealing container 21. The gas sprayed out of the head 211 in the mounting hole 131 may enter the gas channel 132 more easily, thereby increasing the initiation speed of the initiation apparatus 3.
In an example, a cross section of the avoidance hole 133 is circular. The mounting hole 131 has a circular cross section. The avoidance hole 133 is provided coaxially with the mounting hole 131, and a radius of the avoidance hole 133 is greater than a radius of the mounting hole 131. The support seat 13 is threadedly connected to the outer shell 11, so that the connection is reliable and the assembly is convenient. The head 211 of the sealing container 21 is threadedly connected to the support seat 13, so that the connection is reliable and the assembly is convenient. A plurality of gas channels 132 are provided, and the plurality of gas channels 132 are provided at intervals along a circumferential direction of the support seat 13, so that the gas enters the fire extinguishing agent storage container 210 quickly and evenly.
In an illustrative example, as shown in FIG. 4, a cross-sectional area of the second mounting cavity 112 is greater 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. An end face of the support seat 13 close to the first mounting cavity 111 abuts against an end face of
19 20570415_1 (GHMatters) P123715.AU the second mounting cavity 112. The end face of the support seat 13 close to the first mounting cavity 111 protrudes from an inner surface of the first mounting cavity 111 to form a stop face 134 for stopping the striker 31, as shown in FIG. 4.
When assembling, the sealing plug 12 may be first mounted into the first mounting cavity 111 through the second mounting cavity 112, then the striker 31 is mounted into the first mounting cavity 111 through the second mounting cavity 112, then the support seat 13 is mounted into the second mounting cavity 112 until the support seat 13 abuts against a step of the stepped hole, and then the head 211 of the sealing container 21 is mounted into the mounting hole 131 of the support seat 13. In this way, the assembly process of the starting apparatus 100 is simple and convenient.
In addition, in the process of use, when the striker 31 moves to abut against the support seat 13, the striker 31 is stopped by the support seat 13 and cannot continue to move, thereby limiting the sliding stroke of the striker 31 and preventing the sealing container 21 from being excessively deformed and falling off due to excessive movement amplitude of the striker 31.
In an example, the needle portion 312 of the striker 31 is provided with a transition channel 3121 communicated with the gas channel 132, as shown in FIG. 4. In this way, the gas in the sealing container 21 may also enter the gas channel 132 through the transition channel 3121, thereby further improving the initiation speed of the initiation apparatus 3. In addition, it may further reduce a mass of the striker 31 and further reduce the requirement for the trigger 32.
In an illustrative example, as shown in FIG. 4, the housing 1 is provided with at least one spray channel 116 which is communicated with the spout 115. The starting apparatus 100 further includes a sealing valve 4 configured to disconnect a communication between the spray channel 116 and the spout 115. The sealing valve 4 is configured to make the spray channel 116 in communication with the spout 115 under the impact of a fluid (e.g., the fire extinguishing agent 220).
The spray channel 116 is configured to be able to communicate with thefire extinguishing agent storage container 210. The sealing valve 4 ensures that the spray channel 116 is not communicated with the spout 115 when the fire extinguishing device is not used, thereby 20 20570415_1 (GHMatters) P123715.AU preventing property damage or personal injury caused by the spraying of thefire extinguishing agent 220. In a case where afire occurs, when the initiation apparatus 3 opens the sealing container 21, the fire extinguishing agent in the fire extinguishing agent storage container 210 flows to the spray channel 116 under the action of air pressure and opens the sealing valve 4, and then is sprayed out of the spout 115 to extinguish the fire. Apparently, when the staring apparatus 100 is used for other devices, the spray channel 116 is configured to be able to communicate with container bodies of other devices.
In an example, the sealing valve 4 may be a metal sealing plug, which is in interference
cooperation with the housing 1. At least one sealing ring is provided between the sealing valve
4 and the housing 1 to further improve the sealing reliability of the sealing valve 4. An outer
side wall of the sealing valve 4 is provided with a sealing groove 3113 for mounting the sealing
ring.
In an example, a quantity of the spray channels 116 may be equal to a quantity of the
spouts 115, and the spray channels 116 may be in one-to-one correspondence with the spouts
115. In this case, a quantity of the sealing valves 4 may be equal to the quantity of the spray
channels 116, and the sealing valves 4 may be in one-to-one correspondence with the spray
channels 116, so as to ensure that none of the spray channels 116 is communicated with the
spout 115 when there is no fire.
A quantity of the spray channels 116 may not be equal to a quantity of the spouts 115. For
example, the spray channel 116 may have a three-way structure, a four-way structure, and the
like, so that one spray channel 116 may communicate with three or four spouts 115, which is
beneficial to reducing the quantity of the sealing valves 4, thereby simplifying the product
structure and reducing the product cost.
In an illustrative example, as shown in FIG. 4, the starting apparatus 100 further includes
a siphon 5 fixedly connected to the housing 1 and in communication with the spray channel
116.
After the assembly of the starting apparatus 100 and thefire extinguishing agent storage
container 210 is completed, the siphon 5 is inserted into thefire extinguishing agent storage
container 210. The siphon 5 can suck the fire extinguishing agent 220 in the fire extinguishing 21 20570415_1 (GHMatters) P123715.AU agent storage container 210 into the spray channel 116 by the siphon principle, so that the fire extinguishing agent 220 continuously enters the spray channel 116, thereby improving the extinguishing efficiency. In an example, the siphon 5 is a plastic pipe, and the siphon 5 is threadedly connected to the housing 1.
Apparently, for a small fire extinguishing device, there is a relatively small amount of fire
extinguishing agent 220, so the siphon 5 may be eliminated. Alternatively, in the case where the
fire extinguishing agent storage container 210 is located above the starting apparatus 100, the
fire extinguishing agent 220 may automatically flow to the spray channel 116 under the action
of gravity, and the siphon 5 may also be eliminated in this case.
In an illustrative example, as shown in FIG. 4, a third mounting cavity 113 and an
avoidance cavity 117 communicated with the third mounting cavity 113 are also provided in the
housing 1. The sealing valve 4 is mounted in the third mounting cavity 113 to disconnect the
communication between the spray channel 116 and the spout 115, and is configured to be able
to move into the avoidance cavity 117 under the impact of a fluid (such as the fire extinguishing
agent 220) to make the spray channel 116 in communication with the spout 115.
In this way, the sealing valve 4 is still located in the housing 1 after being impacted by the
fire extinguishing agent 220, which can prevent property damage or personal injury caused by
the pop-out of the sealing valve 4.
In an illustrative example, as shown in FIG. 4, the starting apparatus 100 further includes
an elastic member 6 provided in the housing 1 and abutting against the sealing valve 4 for
restricting movement of the sealing valve 4 towards the avoidance cavity 117.
The elastic member 6 may exert a force on the sealing valve 4, so as to improve the
position stability of the sealing valve 4, and prevent property damage or personal injury caused
by accidental spraying of the fire extinguishing agent 220 when there is no fire.
The elastic member 6 may be a compression spring, an elastic sheet, a silicon ball or other
structures.
In an illustrative example, as shown in FIG. 4, the housing 1 includes a sealing cover 14
and an outer shell 11. The outer shell 11 is provided with a fourth mounting cavity 114 with
22 20570415_1 (GHMatters) P123715.AU openings at both ends. One end of the fourth mounting cavity 114 is communicated with the third mounting cavity 113, and the sealing cover 14 is used to seal an end of the fourth mounting cavity 114 away from the third mounting cavity 113.
The housing 1 is split into a plurality of components such as the outer shell 11, the sealing
cover 14, and the like, which is beneficial to reducing the processing difficulty of each
component, reasonably selecting the material of each component according to the need, and
facilitating the assembly of the components inside the housing 1, thereby optimizing the
structure of the starting apparatus 100 and reducing the assembly difficulty of the starting
apparatus 100.
In the assembly process, the sealing valve 4 may be first mounted into the third mounting
cavity 113 through the fourth mounting cavity 114, the elastic member 6 is then mounted into
the outer shell 11, so that the elastic member 6 abuts against the sealing valve 4, and then the
sealing cover 14 is mounted.
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 may
limit the elastic member 6 and prevent the elastic member 6 from tilting or displacing or the
like, thereby improving the operational reliability of the elastic member 6.
In an illustrative 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
may be inserted into the limiting groove 42, which is beneficial to further preventing the elastic
member 6 from tilting, displacing and the like, and ensuring a good cooperation between the
elastic member 6 and the sealing valve 4.
In an example, as shown in FIG. 4, the end of the sealing valve 4 facing the sealing cover
14 is further provided with a limiting boss 41. A cross-sectional area of the limiting boss 41 is
greater than a cross-sectional area of the third mounting cavity 113, so that the sealing valve 4
may be prevented from being stuck in the third mounting cavity 113 and affecting the normal
spraying of the fire extinguishing agent 220.
23 20570415_1 (GHMatters) P123715.AU
As shown in FIG. 7, yet another embodiment of the present application provides a starting
apparatus 100. The starting apparatus 100 includes a housing 1, a gas generation apparatus 2
and an initiation apparatus 3.
The housing 1 is provided with at least one spout 1513, and a sealed cavity 1113 is
provided in the housing 1. As shown in FIG. 2, the gas generation apparatus 2 includes an
integrated sealing container 21 and a driving medium 22 sealed in the sealing container 21. The
sealing container 21 is connected to the housing 1. The initiation apparatus 3 is located outside
the gas generation apparatus 2. The initiation apparatus 3 includes a striker 31 and a trigger 32.
The striker 31 is provided corresponding to the sealing container 21 and configured to pierce
the sealing container 21 so that the driving medium 22 is sprayed out of the sealing container 21
and forms a gas. One end of the trigger 32 is located in the sealed cavity 1113, and the other
end of the trigger 32 extends through the housing 1 to outside the housing 1. The trigger 32 is
used to raise an air pressure in the sealed cavity 1113. The sealed cavity 1113 is provided
corresponding to the striker 31 for directly or indirectly driving the striker 31 to move in a
direction approaching the sealing container 21 by the raised air pressure, so that the striker 31
pierces the sealing container 21.
In other words, this embodiment differs from the foregoing first embodiment (as shown in
FIGS. 1 and 2) in that:
the housing 1 is provided with at least one spout 1513, and a sealed cavity 1113 is
provided in the housing 1. The initiation apparatus 3 includes a striker 31 and a trigger 32. The
striker 31 is provided corresponding to the sealing container 21 and is configured to pierce the
sealing container 21 so that the driving medium 22 is sprayed out of the sealing container 21
and forms a gas. One end of the trigger 32 is located in the sealed cavity 1113, and the other
end of the trigger 32 extends through the housing 1 to outside the housing 1. The trigger 32 is
used to raise the air pressure in the sealed cavity 1113. The sealed cavity 1113 is provided
corresponding to the striker 31 for directly or indirectly driving the striker 31 to move in a
direction approaching the sealing container 21 by the raised air pressure, so that the striker 31
pierces the sealing container 21.
This embodiment differs from the foregoing second embodiment (shown in FIGS. 4 and 5)
24 20570415_1 (GHMatters) P123715.AU in that: a sealed cavity 1113 is provided in the housing 1. One end of the trigger 32 is located in the sealed cavity 1113, and the other end of the trigger 32 extends through the housing 1 to outside the housing 1. The trigger 32 is used to raise an air pressure in the sealed cavity 1113. The sealed cavity 1113 is provided corresponding to the striker 31 for directly or indirectly driving the striker 31 to move in a direction approaching the sealing container 21 by the raised air pressure, so that the striker 31 pierces the sealing container 21.
As shown in FIG. 7, the initiation apparatus 3 includes a striker 31 and a trigger 32. The trigger 32 is used to drive the striker 31 to move. The striker 31 may quickly pierce the sealing container 21 by a tip portion thereof without generating sparks, thus being safe to use and having high opening efficiency.
As shown in FIG. 7, a sealed cavity 1113 is provided in the housing 1, and one end of the trigger 32 is located in the sealed cavity 1113. When one end of the trigger 32 located outside the sealed cavity 1113 is triggered, the trigger 32 initiates an increase of the air pressure in the sealed cavity 1113, and the increased air pressure in the sealed cavity 1113 may directly or indirectly act on the striker 31, thereby directly or indirectly driving the striker 31 to move and causing the striker 31 to pierce the sealing container 21. This prevents the trigger 32 from being directly inserted into the sealing container 21 to cause the gas generation apparatus 2 to generate gas by triggering the combustion or explosion of the driving medium 22, thereby avoiding the use of a pyrotechnic product as the gas generation apparatus 2.
In an illustrative example, as shown in FIG. 7, a piston 16 is provided in the housing 1. The piston 16 is in sliding cooperation with the housing 1, and the piston 16 and the housing 1 enclose the sealed cavity 1113. The striker 31 is fixedly connected to the piston 16. The trigger 32 is used to raise the air pressure in the sealed cavity 1113 to drive the piston 16 to drive the striker 31 to move in a direction approaching the sealing container 21.
In this embodiment, the trigger 32 is specifically used to raise the air pressure in the sealed cavity 1113, and then the piston 16 is driven to move by the raised air pressure. Since the piston 16 is fixedly connected to the striker 31, the piston 16 is able to drive the striker 31 to move synchronously. It is equivalent to the striker 31 being indirectly driven to move in a 25 20570415_1 (GHMatters) P123715.AU direction approaching the sealing container 21 by the raised air pressure in the sealed cavity
1113.
Apparently, when the striker 31 and the housing 1 enclose the sealed cavity 1113, the
striker 31 may be directly driven to move in a direction approaching the sealing container 21 by
the raised air pressure in the sealed cavity 1113.
Compared with directly driving the striker 31 to move, the striker 31 is driven to move by
the piston 16, which is not only conducive to simplifying the structure of the striker 31, but also
conducive to improving the sealing of the sealed cavity 1113.
At least one sealing ring may be provided between the piston 16 and the housing 1 to
further improve the sealing of the sealed cavity 1113. In an example, a sealing groove for
mounting the sealing ring may be provided on an outer side wall of the piston 16 accordingly.
The striker 31 and the piston 16 may be fixedly connected by means of interference cooperation,
insert molding and the like.
In an example, the trigger 32 includes an electrical trigger 32. As shown in FIG. 4, the
electrical trigger 32 includes a resistor 321 and a connecting wire 322 connected to the resistor
321, the resistor 321 is located within the sealed cavity 13 and the connecting wire 322 extends
through the housing 1 to outside the housing 1. Apparently, the trigger 32 may also include a
thermal trigger 32, or the trigger 32 may include both the electrical trigger 32 as described
above and the thermal trigger 32 as described above.
In an illustrative example, as shown in FIG. 7, the housing 1 includes an outer shell 11
and a sealing structure 12. The outer shell 11 is provided with a first mounting cavity 111. The
striker 31 and the piston 16 are located in the first mounting cavity 111. One end of the first
mounting cavity 111 is provided as an opening end. The sealing structure 12 is connected to the
outer shell 11 and seals the opening end of the first mounting cavity 111. The trigger 32 is
configured to penetrate the sealing structure 12. A space between the sealing structure 12 and
the piston 16 forms the sealed cavity 1113.
The housing 1 is split into a plurality of components such as the outer shell 11, the sealing
structure 12, and the like, which is beneficial to reducing the processing difficulty of each
component, reasonably selecting the material of each component according to the need, and 26 20570415_1 (GHMatters) P123715.AU facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100.
Furthermore, the sealing structure 12 and the piston 16 define the sealed cavity 1113 in
the outer shell 11, and the sealing structure 12 and the piston 16 can seal two ends of the sealed
cavity 1113, thereby facilitating the improvement of the sealing reliability of the sealed cavity
1113.
The outer shell 11 may be a metal outer shell 11, and the piston 16 may be a silicone
piston or a rubber piston. In an example, the striker 31 may be made of metal having a high
hardness so as to pierce the sealing container 21 rapidly.
In an illustrative example, as shown in FIG. 7, the sealing structure 12 includes a first
cover 121 and a sealing plug 122. The first cover 121 is connected to the outer shell 11 and
covers the opening end of the first mounting cavity 111. The sealing plug 122 is at least
partially located within the first mounting cavity 111 and abuts against the first cover 121. A
space between the sealing plug 122 and the piston 16 forms the sealed 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 sealed cavity 1113 in the outer shell 11, and the sealing plug
122 and the piston 16 may seal two ends of the sealed cavity 1113, thereby facilitating the
improvement of the sealing reliability of the sealed cavity 1113. The first cover 121 may fix the
sealing plug 122 to prevent the sealing plug 122 from moving or falling off or the like, thus
improving the operational reliability of the sealing plug 122. The sealing plug 122 may be a
silicone plug or a rubber plug.
In an illustrative example, the first mounting cavity 111 includes a mounting groove 1111
and a sliding channel 1112. The mounting groove 1111 is used for mounting the first cover 121
and the sealing plug 122. The sliding channel 1112 is communicated with the mounting groove
1111. A cross-sectional area of the sliding channel 1112 is smaller than a cross-sectional area of
the mounting groove 1111, so that a support surface 1114 (as shown in FIG. 9) is formed
between the sliding channel 1112 and the mounting groove 1111. The sealing plug 122 abuts
against the support surface 1114. The piston 16 is located within and in sliding cooperation with 27 20570415_1 (GHMatters) P123715.AU the sliding channel 1112.
Since the cross-sectional areas of the mounting groove 1111 and the sliding channel 1112 are different, a stepped hole structure is formed in the first mounting cavity 111. Moreover, an inlet end of the stepped hole structure is relatively greater in diameter, so that the piston 16 and the striker 31 can be quickly and conveniently inserted into the sliding channel 1112, thereby reducing the assembly difficulty and improving the assembly efficiency. In addition, a support surface 1114 of the stepped hole structure also has a limiting role to the sealing plug 122 to prevent the sealing plug 122 from moving into the sliding channel 1112, thereby further improving the stability of the sealing plug 122. In addition, the support surface 1114 of the stepped hole provides a function of assembly positioning for the sealing plug 122. When the sealing plug 122 abuts against the support surface 1114, the sealing plug 122 is mounted in place, which can prevent the sealing plug 122 from being excessively squeezed and affecting the service life thereof.
In an exemplary 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 trigger 32 is configured to penetrate the sealing plug 122 and the first cover 121. A part of the sealing plug 122 is limited in the limiting groove 1211 of the first cover 121, which is beneficial to further improving the stability of the sealing plug 122. In addition, in the present scheme, the first cover 121, the sealing plug 122, and the trigger 32 are assembled into a module, and then the module is assembled to the outer shell 11, which is beneficial to reducing the assembly difficulty and improving the assembly efficiency. The first cover 121 may be a metal cover. The first cover 121 may be threadedly connected to the outer shell 11, so that the connection is reliable and the assembly is convenient.
In an illustrative example, as shown in FIG. 7, the housing 1 is provided with a mounting hole 131 and at least one gas channel 132. The sealing container 21 includes a head 211 and a body 212, as shown in FIG. 8. The head 211 is mounted in the mounting hole 131 and is provided corresponding to the striker 31 for spraying out the gas formed by the driving medium 22. The gas channel 132 is communicated with the mounting hole 131 and one end of the gas channel 132 penetrates the housing 1 for delivering the gas formed by the driving medium 22 to
28 20570415_1 (GHMatters) P123715.AU the fire extinguishing agent storage container 210.
The housing 1 is provided with the mounting hole 131 and the gas channel 132. The mounting hole 131 is used for mounting the head 211 of the sealing container 21, and the body 212 of the sealing container 21 may be inserted into thefire extinguishing agent storage container 210. The gas channel 132 is used for delivering gas to the fire extinguishing agent storage container 210 so as to rapidly pressurize thefire extinguishing agent storage container 210 and then spray out thefire extinguishing agent 220. The gas channel 132 is communicated with the mounting hole 131 to ensure that the gas sprayed out of the head 211 of the sealing container 21 can enter the gas channel 132. One end of the gas channel 132 penetrates the housing 1 to ensure that the gas channel 132 can communicate with thefire extinguishing agent storage container 210 after the housing 1 is assembled with thefire extinguishing agent storage container 210.
In an illustrative example, as shown in FIG. 7, the housing 1 includes an outer shell 11 and a support seat 13. A second mounting cavity 112 is provided in the outer shell 11. The support seat 13 is mounted in the second mounting cavity 112. The mounting hole 131 and the gas channel 132 are provided on the support seat 13.
The housing 1 is split into a plurality of components such as the outer shell 11, the support seat 13, and the like, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to the need, and facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100.
In an example, the support seat 13 is threadedly connected to the outer shell 11, so that the connection is reliable and the assembly is convenient. The head 211 of the sealing container 21 is threadedly connected to the support seat 13, so that the connection is reliable and the assembly is convenient. A plurality of gas channels 132 may be provided, and the plurality of gas channels 132 are provided at intervals along a circumferential direction of the support seat 13, as shown in FIG. 7, so that the gas enters the fire extinguishing agent storage container 210 quickly and evenly. 29 20570415_1 (GHMatters) P123715.AU
In an illustrative example, as shown in FIG. 7, the starting apparatus 100 further includes
a first sealing diaphragm 141. The first sealing diaphragm 141 is provided in the second
mounting cavity 112 and located between the striker 31 and the sealing container 21, and abuts
against an end of the support seat 13 close to the striker 31. When a fire occurs, the striker 31
pierces the first sealing diaphragm 141, and further pierces the sealing container 21. The
provision of the first sealing diaphragm 141 is conducive to preventing the striker 31 from
being accidentally triggered and causing the sealing container 21 to be pierced, thereby
improving the safety of the starting apparatus 100. The first sealing diaphragm 141 may be
made of aluminum or other material.
In an illustrative example, as shown in FIG. 7, the housing 1 is provided with at least one
spray channel 114 which is communicated with the spout 1513. The starting apparatus 100
further includes a second sealing diaphragm 142. The second sealing diaphragm 142 is
provided corresponding to the spout 1513 and configured to disconnect a communication
between the spray channel 114 and the spout 1513.
The spray channel 114 is configured to be able to communicate with thefire extinguishing
agent storage container 210. The second sealing diaphragm 142 ensures that the spray channel
114 is not communicated with the spout 1513 when the fire extinguishing device 200 is not
used, thereby preventing property damage or personal injury caused by the spraying of the fire
extinguishing agent 220. In a case where a fire occurs, when the initiation apparatus 3 opens the
sealing container 21, the fire extinguishing agent 220 in thefire extinguishing agent storage
container 210 flows to the spray channel 114 under the action of air pressure and further breaks
through the second sealing diaphragm 142, and then is spayed out of the spout 1513 to
extinguish the fire. Apparently, when the staring apparatus 100 is used for other devices, the
spray channel 114 is configured to be able to communicate with container bodies of other
devices. Compared with a scheme where a sealing valve is used to disconnect the
communication between the spout 1513 and the spray channel 114 and an elastic member is
further used to improve the stability of the sealing valve, the structure of the present scheme is
simpler. The second sealing diaphragm 142 may be an aluminum diaphragm or other
diaphragm.
30 20570415_1 (GHMatters) P123715.AU
In an example, a quantity of the spray channels 114 may be equal to a quantity of the
spouts 1513, and the spray channels 114 may be in one-to-one correspondence with the spouts
1513. In this case, a quantity of the second sealing diaphragms 142 may be equal to the quantity
of the spray channels 114, and the second sealing diaphragms 142 may be in one-to-one
correspondence with the spray channels 114, so as to ensure that none of the spray channels 114
may be communicated with the spout 115 when there is no fire.
A quantity of the spray channels 114 may not be equal to a quantity of the spouts 1513.
For example, the spray channel 114 may have a three-way structure, a four-way structure, and
the like, so that one spray channel 114 may communicate with three or four spouts 1513, which
is beneficial to reducing the quantity of the second sealing diaphragm 142, thereby simplifying
the product structure and reducing the product cost.
In an illustrative example, as shown in FIG. 7, the starting apparatus 100 further includes
a siphon 4 fixedly connected to the housing 1 and in communication with the spray channel
114.
After the assembly of the starting apparatus 100 and thefire extinguishing agent storage
container 210 is completed, the siphon 4 is inserted into thefire extinguishing agent storage
container 210. The siphon 4 may suck the fire extinguishing agent 220 in the fire extinguishing
agent storage container 210 into the spray channel 114 by the siphon principle, so that the fire
extinguishing agent 220 continuously enters the spray channel 114, thereby improving the
extinguishing efficiency. In an example, the siphon 4 is a plastic pipe, and the siphon 4 is
threadedly connected to the housing 1.
Apparently, for a small fire extinguishing device, there is a relatively small amount of fire
extinguishing agent 220, so the siphon 4 may be eliminated. Alternatively, in the case where the
fire extinguishing agent storage container 210 is located above the starting apparatus 100, the
fire extinguishing agent 220 may automatically flow to the spray channel 114 under the action
of gravity, and the siphon 4 may also be eliminated in this case.
In an illustrative example, as shown in FIG. 7, the housing 1 includes an outer shell 11
and a spray structure 15. A third mounting cavity 113 for mounting the spray structure 15 is
provided in the outer shell 11. One end of the third mounting cavity 113 is provided as an 31 20570415_1 (GHMatters) P123715.AU opening end, and the other end of the third mounting cavity 113 is communicated with the spray channel 114. A spout 1513 is provided on the spray structure 15. The second sealing diaphragm 142 is provided between the spray channel 114 and the spray structure 15.
The housing 1 is split into a plurality of components, such as the outer shell 11, the spray structure 15, and the like, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to the need, and facilitating the assembly of the components inside the housing 1, thereby optimizing the structure of the starting apparatus 100 and reducing the assembly difficulty of the starting apparatus 100. The second sealing diaphragm 142 may be mounted first, and then the spray structure 15 is mounted.
In an illustrative example, as shown in FIG. 7, the spray structure 15 includes a second cover 152 and a nozzle 151. The second cover 152 is provided at the opening end of the third mounting 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 mounted at the through hole and is communicated with the third mounting cavity 113. The spout 1513 is provided on the nozzle 151.
The spray structure 15 includes a second cover 152 fixedly connected to the outer shell 11, and a nozzle 151. The nozzle 151 is mounted on the second cover 152 to facilitate selection of a desired shape of the nozzle 151 as needed to optimize the product structure.
In an example, the second cover 152 is threadedly connected to the outer shell 11, and the nozzle 151 is threadedly connected to the second cover 152. By threaded connection, the connection is reliable and the assembly is convenient. As shown in FIG. 7, an input channel 1511 and an output channel 1512 may be provided within the nozzle 151. The input channel 1511 is communicated with the third mounting cavity 113. The output channel 1512 is communicated with the input channel 1511, and an outlet of the output channel 1512 is formed as a spout 1513. A quantity of the input channel 1511 may be one or more, and a quantity of the output channel 1512 may be one or more. The nozzle 151 may have a generally cylindrical structure, the input channel(s) 1511 may be provided along a radial direction of the nozzle 151, and the output channel(s) 1512 may be provided along an axial direction of the nozzle 151. 32 20570415_1 (GHMatters) P123715.AU
As shown in FIG. 3, an embodiment of the present application further provides a fire
extinguishing device 200 including a fire extinguishing agent storage container 210 and the
starting apparatus 100 as described in the above embodiments.
The fire extinguishing agent storage container 210 is filled with a fire extinguishing agent
220. The housing 1 of the starting apparatus 100 is connected to thefire extinguishing agent
storage container 210, and the gas generation apparatus 2 of the starting apparatus 100 is used
for delivering the gas, which drives the fire extinguishing agent 220 to be sprayed out, into the
fire extinguishing agent storage container 210.
In an embodiment of the present application, the starting apparatus 100 is the starting
apparatus provided by any one of the foregoing first embodiments (as shown in FIGS. 1 and 2),
and thus has all the beneficial effects of the foregoing first embodiments, which will not be
repeated here.
A shape of the fire extinguishing agent storage container 210 is not limited. For example,
a cross section of the fire extinguishing agent storage container 210 may be circular, elliptical,
triangular, polygonal, or the like.
As shown in FIG. 3, thefire extinguishing agent storage container 210 is provided with at
least one fire extinguishing agent spout 2106.
In this embodiment, the fire extinguishing agent storage container 210 is provided with at
least one fire extinguishing agent spout 2106, through which the fire extinguishing agent 220 in
the fire extinguishing agent storage container 210 can be sprayed out. Compared with the
scheme in which the fire extinguishing agent spout 2106 is provided on the starting apparatus
100, the starting apparatus 100 and the fire extinguishing agent spout 2106 are independent of
each other in this scheme, which is beneficial to simplifying the structure of the starting
apparatus 100, and facilitating improvement on the basis of the existing products, thereby
reducing the production cost. A quantity of the fire extinguishing agent spout 2106 may be one
or more, and the plurality of fire extinguishing agent spouts 2106 is beneficial to improving fire
extinguishing efficiency.
33 20570415_1 (GHMatters) P123715.AU
In an illustrative example, as shown in FIG. 3, the fire extinguishing agent storage
container 210 includes a second outer shell 2102 and a third cover 2104. The second outer shell
2102 is provided with a first opening 2108 and a second opening 2110. The starting apparatus
100 is provided at the first opening 2108. The third cover 2104 is provided at the second
opening 2110, and the third cover 2104 is provided with thefire extinguishing agent spout
2106.
The fire extinguishing agent storage container 210 is split into a plurality of components
such as the second outer shell 2102 and the third cover 2104, which is beneficial to simplifying
the structure of each component and reducing the processing difficulty of each component. The
second outer shell 2102 is provided with a first opening 2108 and a second opening 2110. The
first opening 2108 is fitted with the starting apparatus 100 to ensure the normal connection
between the starting apparatus 100 and the second outer shell 2102. The second opening 2110 is
fitted with the third cover 2104 to ensure normal assembly of the third cover 2104 and the
second outer shell 2102. The fire extinguishing agent spout 2106 is provided on the third cover
2104, thereby avoiding opening holes in the second outer shell 2102 and facilitating the
improvement of the strength of the second outer shell 2102.
The first opening 2108 may be specifically fitted with the first cover 112 of the starting
apparatus 100, so that the first cover 112 may be threadedly connected and fixed to the second
outer shell 2102, the connection strength is high, and the assembly is convenient and quick. The
third cover 2104 may also be threadedly connected and fixed to the second outer shell 2102, the
connection strength is high, and the assembly is convenient and quick.
In an example, at least one sealing ring is provided between the first cover 112 and the
second outer shell 2102, and an outer side wall of the first cover 112 is provided with a sealing
groove 1121 for mounting the sealing ring, as shown in FIG. 3.
In an illustrative example, the second outer shell 2102 is provided with a mounting groove
2114, the third cover 2104 is mounted in the mounting groove 2114, one end of the mounting
groove 2114 forms the second opening 2110, and an end of the mounting groove 2114 away
from the second opening 2110 is provided with a second avoidance notch 2118. The fire
extinguishing device 200 further includes a second sealing diaphragm 2112 that seals the
34 20570415_1 (GHMatters) P123715.AU second avoidance notch 2118 and is sandwiched between the third cover 2104 and a groove wall of the mounting groove 2114.
In this embodiment, the second sealing diaphragm 2112 ensures that the fire extinguishing agent 220 can be stably sealed in the second outer shell 2102 when there is no fire. When a fire occurs, after the gas generation apparatus 2 sprays out gas into the second outer shell 2102, the fire extinguishing agent 220 may break through the second sealing diaphragm 2112 and be sprayed out to extinguish the fire. By adopting the second sealing diaphragm 2112, there is no need to additionally provide a sealing valve and a structure for limiting the sealing valve, thereby simplifying the structure of the fire extinguishing device 200 and facilitating the reduction of the production cost of the fire extinguishing device 200.
The second sealing diaphragm 2112 may be an aluminum diaphragm.
In an illustrative example, the starting apparatus 100 is located within the fire extinguishing agent storage container 210, as shown in FIG. 3. Compared with the scheme in which the starting apparatus 100 is placed outside the fire extinguishing agent storage container 210, the starting apparatus 100 is provided within thefire extinguishing agent storage container 210 in this scheme, which greatly simplifies the external structure of the fire extinguishing device 200, facilitates the storage and transportation of the fire extinguishing device 200, and facilitates the gas sprayed from the gas generation apparatus 2 to directly enter the fire extinguishing agent storage container 210 without gas leakage.
In an example, the fire extinguishing agent storage container 210 is provided with at least one mounting bracket 2116 as shown in FIG. 3.

The spout 1513 of the starting apparatus 100 is configured to be able to communicate with the fire extinguishing agent storage container 210.
The fire extinguishing device 200 provided in this embodiment has all the advantages of the foregoing third embodiment since it includes the starting apparatus 100 provided by the foregoing third embodiment, which is not repeated here.
In an exemplary embodiment, a plurality of starting apparatuses 100 are provided, as shown in FIG. 12.
Compared with a single starting apparatus 100, the plurality of starting apparatuses 100 in this scheme may effectively increase the gas production, thereby effectively increasing the air pressure in the fire extinguishing agent storage container 210, enabling the fire extinguishing agent to have higher spraying intensity, meeting the requirements for fire extinguishing agent spray intensity in demanding application sites, and further improving the fire extinguishing efficiency of the fire extinguishing device.
Moreover, due to different application sites of the fire extinguishing device, the requirements for fire extinguishing agent spray intensity are different.

The sliding portion 311 is located in the first mounting cavity 111 and is in sliding cooperation with the outer shell 11. The needle portion 312 is inserted into the avoidance hole 133. A sealed cavity 1111 is formed between the sealing plug 12 and the striker 31. The sealing container 21 includes a head 211 and a body 212. The head 211 is mounted in the mounting hole 131, and the body 212 is inserted into thefire extinguishing agent storage container 210.

After the connecting wire 322 of the electrical trigger is powered on, the resistor 321 generates heat so that the air pressure in the sealed cavity 1111 is raised, and the striker 31 is squeezed to pierce the sealing container 21 of the gas generation apparatus 2. The nitrogen gas in the sealing container 21 enters the fire extinguishing agent storage container 210 through the gas channel 132, and squeezes the fire extinguishing agent, i.e., heptafluoropropane, in the fire extinguishing agent storage container 210 into the siphon 5. The sealing valve 4 is lifted by the fire extinguishing agent, and the fire extinguishing agent is sprayed out of the spout 115.
Specific Example 3 (as shown in FIGS. 7 to 9)
As shown in FIG. 9, this specific example provides a gas fire extinguishing device including a starting apparatus 100 and afire extinguishing agent storage container 210 filled with a gas fire extinguishing agent.
As shown in FIG. 7, the starting apparatus 100 includes a housing 1, a gas generation apparatus 2, an initiation apparatus 3, a piston 16, a first sealing diaphragm 141, a second sealing diaphragm 142, and a siphon 4. The housing 1 includes an outer shell 11, a sealing structure 12, a support seat 13, and a spray structure 15. As shown in FIG. 8, the gas generation apparatus 2 includes a sealing container 21 and a driving medium 22 encapsulated in the sealing container 21. The initiation apparatus 3 includes a striker 31 and an electrical trigger. The sealing structure 12 includes a first cover 121 and a sealing plug 122. The spray structure 15 includes a second cover 152 and a nozzle 151.
The outer shell 11 is threadedly connected to the fire extinguishing agent storage container 210. A first mounting cavity 111, a second mounting cavity 112, and a third mounting cavity 113 are provided in the outer shell 11. The first mounting cavity 111 includes a mounting groove 1111 and a sliding channel 1112. A support surface 1114 is formed between the 40 20570415_1 (GHMatters) P123715.AU mounting groove 1111 and the sliding channel 1112. The first cover 121 is threadedly connected to a groove wall of the mounting groove 1111. A part of the sealing plug 122 is limited in the limiting groove 1211 of the first cover 121. The sealing plug 122 abuts against the first cover 121 and the support surface 1114. The piston 16 and the striker 31 are mounted in the sliding channel 1112. A space between the piston 16 and the sealing plug 122 forms the sealed cavity 1113. The striker 31 is fixedly connected to the piston 16. A resistor 321 of the electrical trigger is located within the sealed cavity 1113, and a connecting wire 322 extends through the sealing plug 122 and the first cover 121 to outside the outer shell 11.
The support seat 13 is mounted in the second mounting cavity 112 by threaded connection.
A head 211 of the sealing container 21 is threadedly connected to the support seat 13, and a
body 212 of the sealing container 21 is inserted into thefire extinguishing agent storage
container 210. The support seat 13 is provided with a gas channel 132 which is communicated
with the fire extinguishing agent storage container 210. A first sealing diaphragm 141 is
provided between the head 211 of the sealing container 21 and the striker 31 and is sandwiched
between the support seat 13 and a top wall of the second mounting cavity 112.
The second cover 152 is fixedly connected to an inner side wall of the third mounting
cavity 113 by threaded connection. The nozzle 151 is fixedly connected to the second cover 152
by threaded connection. The nozzle 151 is provided with a spout 1513. The siphon 4 is a plastic
pipe, which is fixedly connected to the outer shell 11 by threaded connection and is
communicated with a spray channel 114. A second sealing diaphragm 142 is provided between
the spray channel 114 and a third cover and corresponding to the nozzle 151.
When a fire occurs, the electrical trigger is powered on, and the resistor 321 generates
heat, so that the air pressure in the sealed cavity 1113 is raised. The raised air pressure in the
sealed cavity 1113 drives the piston 16 to move in a direction approaching the gas generation
apparatus 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 sealing container 21, and the driving medium 22
in the sealing container 21 is sprayed out of the sealing container 21 to form a gas. The sprayed
gas enters the fire extinguishing agent storage container 210 through the gas channel 132, so
that the inside of the fire extinguishing agent storage container 210 is pressurized rapidly to
41 20570415_1 (GHMatters) P123715.AU drive the fire extinguishing agent 220 to enter the fire extinguishing agent spray channel 114 through the siphon 4, break the second sealing diaphragm 142, and be sprayed out of the nozzle 151 to extinguish the fire.
As shown in FIG. 12, an embodiment of the present application further provides a fire extinguishing device, including a housing 200 and a plurality of starting apparatuses 100. The housing 200 is filled with a fire extinguishing agent, and the housing 200 is provided with afire extinguishing agent spout 1513, as shown in FIG. 12. The plurality of starting apparatuses 100 are connected to the housing 200 for delivering a gas into the housing 200 to drive the fire extinguishing agent in the housing 200 to be sprayed out of the fire extinguishing agent spout 1513.
The starting apparatus 100 includes a gas generation apparatus 2 and an initiation apparatus 3, as shown in FIGS. 10 and 12. The gas generation apparatus 2 includes an integrated sealing container 21 and a driving medium 22 sealed in the sealing container 21, as shown in FIG. 11. The initiation apparatus 3 cooperates with the gas generation apparatus 2 for opening the sealing container 21 to cause the driving medium 22 to be sprayed out of the sealing container 21 and form a gas that drives the fire extinguishing agent in the housing 200 to be sprayed out.
The fire extinguishing device provided by the embodiment of the present application includes a housing 200 and a plurality of starting apparatuses 100. The housing 200 is a storage container for a fire extinguishing agent. The housing 200 is provided with a fire extinguishing agent spout 1513 for spraying the fire extinguishing agent. The starting apparatus 100 is used for delivering a gas into the housing 200, so that the fire extinguishing agent in the housing 200 is sprayed out of the fire extinguishing agent spout 1513 under the action of gas pressure, thus realizing the function of initiating the fire extinguishing device. Compared with a single starting apparatus 100, a plurality of starting apparatuses 100 in this scheme may effectively increase the gas production, thereby effectively increasing the air pressure in the housing 200, enabling the fire extinguishing agent to have higher spraying intensity, meeting the requirements for fire extinguishing agent spray intensity in demanding application sites, and further improving the 42 20570415_1 (GHMatters) P123715.AU fire extinguishing efficiency of the fire extinguishing device.
Moreover, due to different application sites offire extinguishing device, the requirements
for fire extinguishing agent spray intensity are different. By adopting this design, the quantity of
the starting apparatuses 100 may be adjusted according to the application sites, so as to meet the
requirements for fire extinguishing agent spray intensity in different application sites and
improve fire extinguishing efficiency.
In addition, the driving medium 22 is encapsulated in the integrated sealing container 21
and the sealing container 21 can be opened by the initiation apparatus 3 whenfire extinguishing
is required, so that the driving medium 22 is sprayed out of the sealing container 21 and forms a
gas capable of driving the fire extinguishing agent to be sprayed out. The gas can enter the
housing 200 to rapidly pressurize the housing 200, thereby enabling the fire extinguishing agent
to be sprayed out under the action of pressure so as to extinguish the fire. In this way, the fire
extinguishing agent does not need to be stored under pressure, thereby fundamentally solving
the problem of pressure leakage of the existing pressure-storage type fire extinguishing device,
eliminating the maintenance cost of periodic pressure charging and improving the operational
reliability of the fire extinguishing device.
In an illustrative example, the fire extinguishing device further includes a siphon 4, as
shown in FIGS. 10 and 12. One end of the siphon 4 is located in the housing 200, and the other
end of the siphon 4 is communicated with thefire extinguishing agent spout 1513. The siphon 4
can suck the fire extinguishing agent in the housing 200 into the fire extinguishing agent spout
1513 by the siphon principle, so that the fire extinguishing agent is continuously sprayed out of
the fire extinguishing agent spout 1513, thereby improving the fire extinguishing efficiency.
In an example, the siphon 4 is a plastic pipe, and the siphon 4 is threadedly connected to
the housing 200.
Apparently, for a small fire extinguishing device, there is a relatively small amount of fire
extinguishing agent, so the siphon 4 can also be eliminated. Alternatively, in the case where the
fire extinguishing agent spout 1513 is located at a bottom of the housing 200, the fire
extinguishing agent may automatically flow to the fire extinguishing agent spout 1513 under
the action of gravity, and the siphon 4 may also be eliminated in this case. 43 20570415_1 (GHMatters) P123715.AU
In an illustrative example, a quantity of the siphons 4 is equal to a quantity of the fire
extinguishing agent spouts 1513, and the siphons 4 are in one-to-one correspondence with the
fire extinguishing agent spouts 1513, as shown in FIG. 12. Thus, each fire extinguishing agent
spout 1513 can continuously and efficiently spray out the fire extinguishing agent, thereby
effectively improving fire extinguishing efficiency.
In an example, as shown in FIG. 12, if the quantity of thefire extinguishing agent spout
1513 is one, the quantity of the siphon 4 is also one. In another example (not shown in the
figures), if a plurality of (for example, two) fire extinguishing agent spouts 1513 are provided, a
plurality of the siphons 4 are also provided.
Apparently, the quantity of the fire extinguishing agent spouts 1513 may not be equal to
the quantity of the siphons 4. For example, if the quantity of thefire extinguishing agent spouts
1513 is greater than the quantity of the siphons 4, some fire extinguishing agent spouts 1513 are
communicated with the siphons 4, and some fire extinguishing agent spouts 1513 are not
communicated with the siphons 4.
In an illustrative example, the siphon 4 is a straight pipe, as shown in FIG. 10. The siphon
4 is a straight pipe, which has simple structure, is easy to assembly, can reduce the flow
resistance of the fire extinguishing agent, and is beneficial to the rapid spraying of the fire
extinguishing agent.
In an illustrative example, the siphon 4 is an elbow pipe, as shown in FIG. 12, and an end
of the siphon 4 away from the fire extinguishing agent spout 1513 is bent and extended in a
direction approaching an inner side wall of the housing 200.
The siphon 4 is an elbow pipe, and is bent and extends in a direction approaching the
inner side wall of the housing 200, so that a terminal of the siphon 4 can face downward when
the fire extinguishing device is used horizontally, ensuring that the siphon 4 can efficiently suck
the fire extinguishing agent in the housing 200, thereby improving the fire extinguishing
efficiency.
In an illustrative example, a quantity of the starting apparatuses 100 is two, as shown in
FIG. 12.
44 20570415_1 (GHMatters) P123715.AU
In an example, as shown in FIG. 12, one starting apparatus 100 is mounted at one end of
the housing 200, and the other starting apparatus 100 is mounted at the other end of the housing
200. In another example (not shown in the figures), two starting apparatuses 100 are mounted at
the same end of the housing 200. In yet another example (not shown in thefigures), one starting
apparatus 100 is mounted at an end of the housing 200, and the other starting apparatus 100 is
mounted at the middle of the housing 200. In still yet another example (not shown in the
figures), both starting apparatuses 100 are mounted at the middle of the housing 200.
Adopting two starting apparatuses 100 can not only increase the gas production so as to
improve the fire extinguishing agent spraying intensity and fire extinguishing efficiency of the
fire extinguishing device, but also avoid too complicated structure of the fire extinguishing
device.
The way of distribution of the two starting apparatuses 100 is not limited and can be
flexibly designed according to the shape of the housing 200 and other factors. For example, the
two starting apparatuses 100 may be respectively provided at two ends of the housing 200; or
the two starting apparatuses 100 may also be provided at the same end of the housing 200; or
one starting apparatus 100 is provided at an end of the housing 200, and the other starting
apparatus 100 is provided at the middle of the housing 200; or both of the starting apparatuses
100 are provided at the middle of the housing 200; or the two starting apparatuses 100 may also
be provided at any other position of the housing 200. Apparently, a quantity of the starting
apparatuses 100 may be three, four, or even more, and specifically may be reasonably designed
according to factors such as capacity, size, use scenario, and the like of thefire extinguishing
device.
In an illustrative example (not shown in the figures), volumes of the sealing containers 21
of the two starting apparatuses 100 are identical. The volumes of the sealing containers 21 of
the two starting apparatuses 100 may be identical, so that the types of the gas generation
apparatuses 2 may be reduced, and the possibility of misassembly during the assembly process
is reduced, thus facilitating assembly.
In an illustrative example, volumes of the sealing containers 21 of the two starting
apparatuses 100 are different, as shown in FIG. 12. The volumes of the sealing containers 21 of
45 20570415_1 (GHMatters) P123715.AU the two starting apparatuses 100 may also be different, which facilitates the reasonable design of the gas production of the fire extinguishing device as required, and also facilitates the flexible design of the mounting positions of the two starting apparatuses 100 as required.
In an illustrative example, the housing 200 includes an outer shell 5 and a mounting cover
1, as shown in FIG. 12. The outer shell 5 is provided with a mounting opening 51. The
mounting cover 1 is provided at the mounting opening 51. The starting apparatus 100 is
mounted on the mounting cover 1.
By splitting the housing 200 into the outer shell 5 and the mounting cover 1, the structure
of the outer shell 5 and the mounting cover 1 may be simplified, and the specific structure of
the mounting cover 1 may be flexibly designed according to the assembly requirements, so as to
reduce the assembly difficulty of the starting apparatus 100 and ensure the integrity and sealing
performance of the outer shell 5.
In an illustrative example, a plurality of mounting openings 51 are provided, as shown in
FIG. 12. A quantity of the mounting covers 1 is equal to the quantity of the mounting openings
51, the mounting covers 1 are in one-to-one correspondence with the mounting openings 51,
and each mounting cover 1 is mounted with at most one starting apparatus 100.
In this scheme, a plurality of mounting openings 51 are provided, and a plurality of
mounting covers 1 are provided correspondingly to ensure that each mounting opening 51 can
be covered. Moreover, compared with the scheme in which a plurality of starting apparatuses
100 are mounted on a single mounting cover 1, at most one starting apparatus 100 is mounted
on each mounting cover 1 in this scheme (i.e., zero or one starting apparatus 100 is mounted),
which is beneficial to simplifying the structure of a single mounting cover 1, reducing the size
of the single mounting cover 1, and avoiding mutual interference between gas generation
apparatuses 2 of different starting apparatuses 100, thereby facilitating the optimization of the
structure and performance of the fire extinguishing device.
The quantity of the mounting covers 1 may be equal to the quantity of the starting
apparatuses 100, and the mounting covers 1 may be in one-to-one correspondence with the
starting apparatuses 100. The quantity of the mounting covers 1 may also be greater than the
quantity of the starting apparatuses 100, so that some of the mounting covers 1 are not mounted 46 20570415_1 (GHMatters) P123715.AU with the starting apparatuses 100, but may be used for spraying or filling thefire extinguishing agent, or may also be used for other purposes.
In an illustrative example, the initiation apparatus 3 includes a striker 31 and a trigger 32, as shown in FIG. 10. The striker 31 is provided corresponding to the sealing container 21 and configured to pierce the sealing container 21 so as to open the sealing container 21. The trigger 32 cooperates with at least one of the gas generation apparatus 2 and the striker 31 and is configured to drive the at least one of the gas generation apparatus 2 and the striker 31 to move in a direction approaching the other of the gas generation apparatus 2 and the striker 31, so that the striker 31 pierces the sealing container 21.
In this embodiment, the initiation apparatus 3 includes a striker 31 and a trigger 32. The trigger 32 may be used to drive the striker 31 to move, so that the striker 31 approaches and pierces the sealing container 21. Alternatively, the trigger 32 may be used to drive the gas generation apparatus 2 to move, so that the gas generation apparatus 2 approaches the striker 31, thereby enabling the striker 31 to pierce the sealing container 21. Alternatively, the trigger 32 may also be used to drive both the striker 31 and the gas generation apparatus 2 to move simultaneously, so that the gas generation apparatus 2 and the striker 31 are brought to approach each other until the striker 31 pierces the sealing container 21, which is beneficial to improving the initiation speed. As long as the striker 31 and the sealing container 21 approach each other gradually, the striker 31 can quickly pierce the sealing container 21 by a tip portion thereof without generating sparks, thus being safe to use and having high opening efficiency.
Apparently, the initiation apparatus 3 is not limited to the above schemes. For example, the initiation apparatus 3 may also include a cutter and a motor, and the motor drives the cutter to move, so that the cutter cuts the sealing container 21 and the sealing container 21 is opened. Alternatively, the initiation apparatus 3 may also include a small electric drill by which the sealing container 21 is opened.
In an illustrative example, the mounting cover 1 is provided with a sealed cavity 1113, as shown in FIG. 10. One end of the trigger 32 is located in the sealed cavity 1113, and the other end of the trigger 32 extends through the mounting cover 1 to outside the mounting cover 1. The trigger 32 is used for raising the air pressure in the sealed cavity 1113. The sealed cavity 47 20570415_1 (GHMatters) P123715.AU
1113 is provided corresponding to the striker 31 for directly or indirectly driving the striker 31
to move in a direction approaching the sealing container 21 by the raised air pressure, so that
the striker 31 pierces the sealing container 21.
When one end of the trigger 32 located outside the sealed cavity 1113 is triggered, the
trigger 32 can initiate an increase of the air pressure in the sealed cavity 1113, and the increased
air pressure in the sealed cavity 1113 can directly or indirectly act on the striker 31, thereby
directly or indirectly driving the striker 31 to move and causing the striker 31 to pierce the
sealing container 21. This prevents the trigger 32 from being directly inserted into the sealing
container 21 to cause the gas generation apparatus 2 to generate gas by triggering the
combustion or explosion of the driving medium 22, thereby avoiding the use of a pyrotechnic
product as the gas generation apparatus 2.
In an illustrative example, as shown in FIG. 10, a piston 16 is provided within the
mounting cover 1. The piston 16 is in sliding cooperation with the mounting cover 1, and the
piston 16 and the mounting cover 1 enclose a sealed cavity 1113. The striker 31 is fixedly
connected to the piston 16. The trigger 32 is used to raise the air pressure in the sealed cavity
1113 to drive the piston 16 to drive the striker 31 to move in a direction approaching the sealing
container 21.
In this embodiment, the trigger 32 is specifically used to raise the air pressure in the
sealed cavity 1113, and then the piston 16 is driven to move by the raised air pressure. Since the
piston 16 is fixedly connected to the striker 31, the piston 16 can drive the striker 31 to move
synchronously. It is equivalent to indirectly drive the striker 31 to move in a direction
approaching the sealing container 21 by the raised air pressure in the sealed cavity 1113.
Apparently, when the striker 31 and the mounting cover 1 enclose a sealed cavity 1113, the
striker 31 may be directly driven to move in a direction approaching the sealing container 21 by
the raised air pressure in the sealed cavity 1113.
Compared with directly driving the striker 31 to move, using the piston 16 to drive the
striker 31 to move is not only conducive to simplifying the structure of the striker 31, but also
conducive to improving the sealing of the sealed cavity 1113.
At least one sealing ring may be provided between the piston 16 and the mounting cover 1 48 20570415_1 (GHMatters) P123715.AU to further improve the sealing of the sealed cavity 1113. In an example, a sealing groove for mounting the sealing ring may be provided on an outer side wall of the piston 16 accordingly. Specifically, the striker 31 and the piston 16 may befixedly connected by means of interference cooperation, insert molding and the like.
In an illustrative example, the trigger 32 includes an electrical trigger. As shown in FIG. 10, the electrical trigger includes a resistor 321 and a connecting wire 322 connected to the resistor 321, the resistor 321 is located within the sealed cavity 1113 and the connecting wire 322 extends through the mounting cover 1 to outside the mounting cover 1.
In another illustrative embodiment (not shown in the figures), the trigger 32 includes a thermal trigger.
In yet another illustrative embodiment (not shown in the figures), the trigger 32 includes both the electrical trigger described above and the thermal trigger described above.
In an illustrative example, the mounting cover 1 includes a cover body 11 and a sealing structure 12, as shown in FIG. 10. The cover body 11 is provided with a first mounting cavity 111, the striker 31 and the piston 16 are located in the first mounting cavity 111, and the first mounting cavity 111 has an opening end.
The sealing structure 12 is connected to the cover body 11 and seals the opening end of the first mounting cavity 111. The trigger 32 penetrates the sealing structure 12, and a space between the sealing structure 12 and the piston 16 forms the sealed cavity 1113.
The mounting cover 1 is split into a plurality of components, such as the cover body 11 and the sealing structure 12, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to needs, and facilitating the assembly of the components inside the mounting cover 1, thereby optimizing the structure of the fire extinguishing device and reducing the assembly difficulty of the fire extinguishing device.
Furthermore, the sealing structure 12 and the piston 16 define the sealed cavity 1113 in the mounting cover 1, and the sealing structure 12 and the piston 16 can seal two ends of the sealed cavity 1113, which facilitates the improvement of the sealing reliability of the sealed
49 20570415_1 (GHMatters) P123715.AU cavity 1113. The cover body 11 may be a metal member, and the piston 16 may be a silicone piston 16 or a rubber piston 16. In an example, the striker 31 may be made of metal having a high hardness so as to pierce the sealing container 21 rapidly.
In an illustrative example, the sealing structure 12 includes a first cover 121 and a sealing
plug 122. The first cover 121 is connected to the cover body 11 and covers the opening end of
the first mounting cavity 111. The sealing plug 122 is at least partially located within the first
mounting cavity 111 and abuts against the first cover 121. A space between the sealing plug
122 and the piston 16 forms the sealed cavity 1113.
The sealing structure 12 includes the first cover 121 and the sealing plug 122.
Furthermore, the sealing plug 122 and the piston 16 define the sealed cavity 1113 in the cover
body 11, and the sealing plug 122 and the piston 16 can seal two ends of the sealed cavity 1113.
In this way, the sealing reliability of the sealed cavity 1113 is improved. The first cover 121
may fix the sealing plug 122 to prevent the sealing plug 122 from moving or falling off or the
like, thereby improving the operational reliability of the sealing plug 122. The sealing plug 122
may be a silicone plug or a rubber plug.
In an illustrative example, the first mounting cavity 111 includes a mounting groove 1111
and a sliding channel 1112. The mounting groove 1111 is used for mounting the first cover 121
and the sealing plug 122. The sliding channel 1112 is communicated with the mounting groove
1111, and a cross-sectional area of the sliding channel 1112 is smaller than a cross-sectional
area of the mounting groove 1111, so that a support surface is formed between the sliding
channel 1112 and the mounting groove 1111. The sealing plug 122 abuts against the support
surface, and the piston 16 is located in the sliding channel 1112 and is in sliding cooperation
with the sliding channel 1112.
Since the cross-sectional areas of the mounting groove 1111 and the sliding channel 1112
are different, a stepped hole structure is formed in the first mounting cavity 111. Moreover, an
inlet end of the stepped hole structure is relatively greater in diameter, so that the piston 16 and
the striker 31 can be quickly and conveniently inserted into the sliding channel 1112, thereby
reducing the assembly difficulty and improving the assembly efficiency. In addition, a support
surface of the stepped hole structure also has a limiting role to the sealing plug 122 to prevent
50 20570415_1 (GHMatters) P123715.AU the sealing plug 122 from moving into the sliding channel 1112, thereby further improving the stability of the sealing plug 122.
In addition, the support surface of the stepped hole provides a function of assembly positioning for the sealing plug 122. When the sealing plug 122 abuts against the support surface, that is, the sealing plug 122 is mounted in place, which can prevent the sealing plug 122 from being excessively squeezed and further affecting the service life thereof.
In an illustrative 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 trigger 32 is configured to penetrate the sealing plug 122 and the first cover 121.
By limiting a part of the sealing plug 122 in the limiting groove 1211 of the first cover 121, the stability of the sealing plug 122 is further improved. In addition, in the present scheme, the first cover 121, the sealing plug 122, and the trigger 32 are assembled into a module, and then the module is assembled to the cover body 11, thereby reducing the assembly difficulty and improving the assembly efficiency.
In an example, the first cover 121 may be a metal cover. The first cover 121 may be threadedly connected to the cover body 11, the connection is reliable and the assembly is convenient.
In an illustrative example, the mounting cover 1 in which the starting apparatus 100 is mounted is provided with a mounting hole 131 and at least one gas channel 132, as shown in FIG. 10.
As shown in FIG. 11, the sealing container 21 includes a head 211 and a body 212. The head 211 is mounted in the mounting hole 131, as shown in FIG. 10. One end of the gas channel 132 is communicated with the mounting hole 131, and the other end of the gas channel 132 is communicated with an internal space of the outer shell 5 for delivering the gas generated by the gas generation apparatus 2 into the outer shell 5.
The mounting hole 131 and the gas channel 132 are provided in the mounting cover 1 in which the starting apparatus 100 is mounted. The mounting hole 131 is used for mounting the head 211 of the sealing container 21, and the body 212 of the sealing container 21 may be
51 20570415_1 (GHMatters) P123715.AU inserted into the outer shell 5. The gas channel 132 is used for delivering gas into the outer shell 5, so that the inside of the outer shell 5 is pressurized rapidly to spray out the fire extinguishing agent. The gas channel 132 is communicated with the mounting hole 131 to ensure that the gas sprayed out of the head 211 of the sealing container 21 can enter the gas channel 132. The other end of the gas channel 132 (i.e., an end close to the housing 200) penetrates the mounting cover 1 to ensure that the gas channel 132 can be communicated with the internal space of the outer shell 5 after the mounting cover 1 is assembled with the outer shell 5.
In an illustrative example, as shown in FIG. 10, the mounting cover 1 includes a cover body 11 and a support seat 13. The cover body 11 is provided with a second mounting cavity 112, the support seat 13 is mounted in the second mounting cavity 112, and the mounting hole 131 and the gas channel 132 are provided on the support seat 13.
The mounting cover 1 is split into a plurality of components, such as the cover body 11 and the support seat 13, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to needs, and facilitating the assembly of the components inside the mounting cover 1, thereby optimizing the structure of the fire extinguishing device and reducing the assembly difficulty of the fire extinguishing device.
In an example, the support seat 13 is threadedly connected to the cover body 11, the head 211 of the sealing container 21 is threadedly connected to the support seat 13. The connection is reliable and the assembly is convenient. A plurality of gas channels 132 are provided, and the plurality of gas channels 132 are provided at intervals along a circumferential direction of the support seat 13, so that the gas enters the outer shell 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 diaphragm 141 is provided in the second mounting cavity 112 and between the striker 31 and the sealing container 21, and abuts against an end of the support seat 13 close to the striker 31. When a fire occurs, the striker 31 pierces the first sealing diaphragm 141, and further pierces the sealing container 21. The provision of the first sealing diaphragm 141 is conducive to preventing the striker 31 from being accidentally triggered and causing the sealing container 21 to be pierced, thereby improving the 52 20570415_1 (GHMatters) P123715.AU safety of the starting apparatus 100. The first sealing diaphragm 141 may be made of aluminum or other material.
In an exemplary embodiment, at least one mounting cover 1 is provided with a fire
extinguishing agent spout 1513, as shown in FIGS. 10 and 12. The fire extinguishing agent
spout 1513 is provided on the mounting cover 1, thereby avoiding drilling holes on the outer
shell 5, and ensuring the integrity and sealing performance of the outer shell 5.
The fire extinguishing agent spout 1513 may be provided on only one mounting cover 1,
or the fire extinguishing agent spouts 1513 may be provided on two or more mounting covers 1.
In an exemplary embodiment, the mounting cover 1 provided with the fire extinguishing
agent spout 1513 is also provided with at least one spray channel 114, as shown in FIG. 10. The
spray channel 114 is communicated with the fire extinguishing agent spout 1513, and a second
sealing diaphragm 142 is provided between the spray channel 114 and the fire extinguishing
agent spout 1513.
The spray channel 114 is configured to be able to communicate with an internal space of
the outer shell 5. The second sealing diaphragm 142 ensures that the spray channel 114 is not
communicated with the fire extinguishing agent spout 1513 when thefire extinguishing device
is not used, thereby preventing property damage or personal injury caused by the spraying of
the fire extinguishing agent. In a case where a fire occurs, when the initiation apparatus 3 opens
the sealing container 21, the fire extinguishing agent in the outer shell 5 flows toward the spray
channel 114 under the action of gas pressure and breaks through the second sealing diaphragm
142, and then is sprayed out of the fire extinguishing agent spout 1513 to extinguish the fire.
Compared with a scheme in which a sealing valve is used to disconnect the communication
between the fire extinguishing agent spout 1513 and the spray channel 114 and an elastic
member is further used to improve the stability of the sealing valve in an example, the structure
of this scheme is simpler. The second sealing diaphragm 142 may be an aluminum diaphragm
or other diaphragm.
In an example, a quantity of the spray channels 114 may be equal to a quantity of the fire
extinguishing agent spouts 1513, and the spray channels 114 may be in one-to-one
correspondence with the fire extinguishing agent spouts 1513. In this case, a quantity of the 53 20570415_1 (GHMatters) P123715.AU second sealing diaphragms 142 may be equal to the quantity of the spray channels 114, and the second sealing diaphragms 142 may be in one-to-one correspondence with the spray channels 114, so as to ensure that none of the spray channels 114 is communicated with the fire extinguishing agent spout 1153 when there is no fire.
A quantity of the spray channels 114 may not be equal to a quantity of the fire extinguishing agent spouts 1513. For example, the spray channel 114 may have a three-way structure, a four-way structure, and the like, so that one spray channel 114 may communicate with three or four fire extinguishing agent spouts 1513, which is beneficial to reducing the quantity of the second sealing diaphragms 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 the fire extinguishing agent spout 1513 includes a cover body 11 and a spray structure 15. The cover body 11 is provided with a third mounting cavity 113 for mounting the spray structure 15. One end of the third mounting cavity 113 is provided as an opening end, and the other end of the third mounting cavity 113 is communicated with the spray channel 114. The fire extinguishing agent spout 1513 is provided on the spray structure 15. The second sealing diaphragm 142 is provided between the spray channel 114 and the spray structure 15.
The mounting cover 1 is split into a plurality of components, such as the cover body 11 and the spray structure 15, which is beneficial to reducing the processing difficulty of each component, reasonably selecting the material of each component according to needs, and facilitating the assembly of the components inside the mounting cover 1, thereby optimizing the structure of the fire extinguishing device and reducing the assembly difficulty of the fire extinguishing device.
The second sealing diaphragm 142 may be mounted first, and then the spray structure 15 is mounted.
In an example, as shown in FIG. 10, the spray structure 15 includes a first cover 121 and a nozzle 151. A second cover 152 is provided at the opening end of the third mounting 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 mounted at the through hole and is communicated with the 54 20570415_1 (GHMatters) P123715.AU third mounting cavity 113. The fire extinguishing agent spout 1513 is provided on the nozzle 151.
The spray structure 15 includes a second cover 152 fixedly connected to the cover body 11, and a nozzle 151. The nozzle 151 is mounted on the second cover 152 to facilitate selection of a desired shape of the nozzle 151 as needed, so as to optimize the product structure. The second cover 152 may be threadedly connected to the cover body 11, and the nozzle 151 may be threadedly connected to the second cover 152. By threaded connection, the connection is reliable and the assembly is easy.
In an example, as shown in FIG. 10, an input channel 1511 and an output channel 1512 may be provided within the nozzle 151. The input channel 1511 is communicated with the third mounting cavity 113. The output channel 1512 is communicated with the input channel 1511, and an outlet of the output channel 1512 is formed as a fire extinguishing agent spout 1513. A quantity of the input channels 1511 may be one or more, and a quantity of the output channels 1512 may be one or more. The nozzle 151 may have a generally cylindrical structure, the input channel(s) 1511 may be provided along a radial direction of the nozzle 151, and the output channel(s) 1512 may be provided along an axial direction of the nozzle 151.
