Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to a multi-stage fire extinguishing board for kitchens. Background Technology
[0002] A common cause of kitchen stove fires is that the oil pan on the stove is left unattended for a long time, causing the oil to splatter out of the pan and be ignited by sparks from the stove. As the fire grows, it can ignite nearby items, such as dishcloths, causing the fire to spread.
[0003] For fires originating from kitchen stoves, the current method of extinguishing them involves installing smoke detectors in the kitchen. Once a fire starts on the stove and ignites nearby items, the smoke will be detected by the smoke detector, alerting people to the fire. After the fire is discovered, people then use fire extinguishers to put it out. This method relies on the electronic component of the smoke detector; if this electronic component malfunctions, it will delay the detection of the fire.
[0004] For fires occurring on kitchen stoves in restaurants, smoke detectors are used for sensing. Restaurants typically have fire suppression systems installed; when the smoke detector detects smoke, the system sprays extinguishing agents. This method also relies on the electronic component of the smoke detector, and a malfunction in this component can delay the detection of a fire.
[0005] Alternatively, ignition-type fire extinguishing bombs can be hung in the restaurant kitchen. When an open flame touches the bomb, it explodes, releasing the extinguishing agent inside to extinguish the fire. However, in this method, because the ignition-type fire extinguishing bomb is independently ignited, the extinguishing range and intensity need to be improved.
[0006] Therefore, how to extinguish fires without relying on electronic components, and how to improve the range and intensity of fire suppression, are the technical problems that need to be solved. Utility Model Content
[0007] To address the aforementioned shortcomings of existing technologies, this invention proposes a multi-stage fire extinguishing plate for kitchens. On the one hand, this invention eliminates the need for electronic components for fire extinguishing, avoiding delays in fire extinguishing due to electronic component failures and improving reliability. On the other hand, this invention enables multi-stage fire extinguishing, which helps to increase the fire extinguishing range and intensity, thereby improving fire extinguishing reliability.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] A multi-stage fire extinguishing board for kitchens includes a support frame, a container, and ignition-type fire extinguishing bombs. The support frame is used to install on the wall in front of the kitchen stove. The container is located on the support frame and contains multiple ignition-type fire extinguishing bombs. Each pair of adjacent ignition-type fire extinguishing bombs is connected in series. The ignition-type fire extinguishing bombs have a plate-like structure. The container has an opening on the side facing the stove, through which the ignition-type fire extinguishing bombs inside the container are exposed.
[0010] Furthermore, the support frame is equipped with an angle adjustment structure, which is used to adjust the tilt angle of the container.
[0011] Furthermore, the angle adjustment structure includes an adjustment rod, one end of which is rotatably connected to the top of the receiving box, and the bottom of the receiving box is rotatably connected to the bottom of the support frame. The other end of the adjustment rod is provided with a pin, and the upper part of the support frame is provided with multiple insertion holes along the vertical direction, with the pin engaging with the insertion holes.
[0012] Furthermore, the ignition-type fire extinguishing bomb includes a shell, an expanding body, a fire extinguishing agent, a first ignition wire, a second ignition wire, a first partition tube, and a second partition tube;
[0013] An expansion body is provided inside the shell, and fire extinguishing agent is filled between the shell and the expansion body. A first ignition wire and a second ignition wire are connected to the expansion body.
[0014] The first ignition wire extends from the side of the shell facing the opening, and the portion of the first ignition wire inside the shell is fitted with a first partition tube, which is used to separate the extinguishing agent and the first ignition wire.
[0015] The second ignition wire extends from the side of the plate facing the adjacent plate. The second ignition wires in two adjacent ignition-type fire extinguishing bombs are connected. The portion of the second ignition wire inside the plate is fitted with a second separator tube, which is used to separate the extinguishing agent and the second ignition wire.
[0016] Furthermore, both the first and second ignition wires are located at the top of the expansion body, and the first and second partition tubes are connected.
[0017] Furthermore, the first ignition wire is spirally coiled on the side of the shell that is exposed from the opening.
[0018] Furthermore, the container includes a box body and a box lid, a sealing ring is provided between the box body and the box lid, the box lid has the opening, the bottom of the box body is rotatably connected to the bottom of the support frame, and the top of the box body is rotatably connected to the adjusting rod.
[0019] Furthermore, the container has a waterproof membrane on the side with the opening.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this invention, when a fire breaks out on the kitchen stove, the device installed on the front wall of the stove can be extinguished by the open flame at the point of origin, eliminating the need for manual firefighting and allowing for fire extinguishing even when the stove is unattended, thus improving safety. Furthermore, this invention does not rely on electronic components, avoiding delays in fire extinguishing due to electronic component malfunctions and improving reliability.
[0022] 2. In this utility model, because multiple ignition-type fire extinguishing bombs are set in the container, and each pair of adjacent ignition-type fire extinguishing bombs are connected in series, once a certain ignition-type fire extinguishing bomb is ignited by an open flame at the fire site, it can continuously ignite the next ignition-type fire extinguishing bomb connected in series with it, thereby achieving multi-stage fire extinguishing, which is beneficial to increase the fire extinguishing range and fire extinguishing intensity, and improve the reliability of fire extinguishing.
[0023] 3. Because the support frame is installed on the wall in front of the kitchen stove, it will not take up space on the stove surface, thus improving space utilization.
[0024] 4. The reduced thickness of the plate-shaped ignition-type fire extinguishing bomb further improves the space utilization near the stove and avoids obstructing the placement of cookware.
[0025] 5. The angle adjustment structure allows for adjustment of the tilt angle of the container, thereby adjusting the tilt angle of the ignition-type fire extinguishing bomb within the container and consequently, the distance between the fire extinguishing bomb and the stovetop. A greater tilt angle brings the fire extinguishing bomb closer to the stovetop; conversely, a smaller tilt angle moves the fire extinguishing bomb further away from the stovetop. Adjusting the distance between the fire extinguishing bomb and the stovetop accommodates cookware of different heights. For example, for flat-bottomed pans, which are lower, the tilt angle of the fire extinguishing bomb can be increased to bring it closer to the pan for more timely fire suppression, thus improving adaptability.
[0026] 6. In the angle adjustment structure, the tilt angle of the container can be changed simply by changing the insertion height of the pin. The lower the insertion height of the pin, the greater the tilt of the container, and the closer the ignition extinguishing bomb in the container is to the stove. This makes the structure simple, easy to adjust, and conducive to improving adjustment efficiency.
[0027] 7. In the ignition-type fire extinguishing bomb, the first ignition wire is used to be directly ignited by the open flame at the fire site, and the second ignition wire is used to ignite adjacent ignition-type fire extinguishing bombs. This allows each ignition-type fire extinguishing bomb to be directly ignited by the open flame at the fire site, and also to be indirectly ignited by adjacent ignition-type fire extinguishing bombs. This improves the flexibility of igniting ignition-type fire extinguishing bombs, thereby improving the reliability of ignition-type fire extinguishing bombs in extinguishing fires in a timely manner.
[0028] 8. The method of coiling the first fuse can increase the coverage of the first fuse and improve the sensitivity of igniting the first fuse.
[0029] 9. The use of a waterproof membrane helps to improve the moisture-proof effect of the first fuse and can improve the reliability of the ignition-type fire extinguishing bomb.
[0030] 10. The sealing ring can improve the sealing effect between the box body and the box cover, and also help improve the moisture protection effect of the first fuse, as well as improve the reliability of the ignition-type fire extinguishing bomb. Attached Figure Description

[0048] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0049] Example 1:
[0050] See Figures 1 to 10 A multi-stage fire extinguishing board for kitchens includes a support frame 1, a container 2, and an ignition-type fire extinguishing bomb 3.
[0051] See Figure 1 The support frame 1 is fixed to the wall 5 in front of the kitchen stove 6 using expansion screws. The support frame 1 is made of stainless steel, which is not easy to rust and has higher strength than wood or plastic, thus improving its reliability.
[0052] See Figure 2 The container 2 is mounted on the support frame 1. The container 2 contains multiple ignition-type fire extinguishing bombs 3. The container 2 has an opening 221 on the side facing the stove 6, which exposes the ignition-type fire extinguishing bombs 3 inside. This allows open flames to come into contact with the ignition-type fire extinguishing bombs 3 and ignite them, causing the ignition-type fire extinguishing bombs 3 to spray extinguishing agent 33 to extinguish the fire. The container 2 is also made of stainless steel. Stainless steel is not easily rusted, extending its service life. Furthermore, stainless steel is stronger than wood or plastic, improving its reliability.
[0053] In this embodiment 1, within the housing 2, every two adjacent ignition-type fire extinguishing bombs 3 are connected in series. When one ignition-type fire extinguishing bomb 3 is ignited, it can ignite the other ignition-type fire extinguishing bombs 3 connected in series, which helps to increase the extinguishing range and extinguishing intensity. Furthermore, in this embodiment 1, the ignition-type fire extinguishing bombs 3 adopt a plate-like structure. The thickness of the plate-like structure of the ignition-type fire extinguishing bombs 3 is reduced, which can improve the space utilization near the stove 6 and avoid obstructing the placement of cookware.
[0054] See Figures 6 to 10 The ignition-type fire extinguishing bomb 3 includes a shell 31, an expansion body 32, a fire extinguishing agent 33, a first ignition wire 34, a second ignition wire 35, a first partition tube 36, and a second partition tube 37.
[0055] See Figure 7 The outer shell 31 is made of plastic. An expansion body 32, which is a firecracker, is installed inside the outer shell 31. A fire extinguishing agent 33, which is a dry powder fire extinguishing agent, is filled between the outer shell 31 and the expansion body 32. When using a firecracker as the expansion body 32, one end of both the first fuse 34 and the second fuse 35 is embedded inside the firecracker, and both the first fuse 34 and the second fuse 35 extend from the top of the firecracker.
[0056] See Figure 7 The first ignition wire 34 extends from the side of the shell 31 facing the opening 221. The portion of the first ignition wire 34 inside the shell 31 is fitted with a first separating tube 36, which is made of plastic. The first separating tube 36 separates the extinguishing agent 33 from the first ignition wire 34, ensuring that the first ignition wire 34 can burn smoothly to the expansion body 32. (See also...) Figure 2 After extending from the shell 31, the first ignition wire 34 is spirally coiled on the side of the shell 31 exposed from the opening 221. This coiling arrangement increases the coverage area of the first ignition wire 34 and improves its ignition sensitivity. To maintain the coiled posture, molten sealing wax is poured onto the surface of the first ignition wire 34. After the sealing wax solidifies, the first ignition wire 34 adheres to the surface of the shell 31 through the sealing wax, thus stabilizing its coiled posture. When igniting the first ignition wire 34, the open flame first melts the sealing wax, exposing the first ignition wire 34, which then ignites it.
[0057] The second ignition wire 35 extends from the side of the shell 31 facing the adjacent shell 31, see [reference]. Figure 10 The second ignition wires 35 in two adjacent ignition-type fire extinguishing bombs 3 are intertwined or tied together. See also Figure 8The portion of the second ignition wire 35 within the shell 31 is fitted with a second separating tube 37, which is also made of plastic. The second separating tube 37 separates the extinguishing agent 33 from the second ignition wire 35, ensuring that the second ignition wire 35 can burn smoothly to the expansion body 32. (See also...) Figure 9 The first partition tube 36 and the second partition tube 37 are connected, and the first partition tube 36 and the second partition tube 37 are an integral structure.
[0058] See Figure 5 The container 2 has a waterproof membrane 24 on one side with an opening 221. The waterproof membrane 24 is made of polyethylene plastic film and is attached to the surface of the container 2 with adhesive (such as transparent tape). When the polyethylene plastic film is exposed to an open flame, it melts rapidly, exposing the first ignition wire 34 on the ignition-type fire extinguishing bomb 3. The use of the waterproof membrane 24 helps to improve the moisture protection of the first ignition wire 34 and improves the reliability of the ignition-type fire extinguishing bomb 3.
[0059] The working principle of this embodiment 1 is as follows:
[0060] In the kitchen, if a fire occurs on an unattended and in-use stove 6 (for example, grease from a pot splashes out and is ignited by sparks from the stove 6), the open flame first melts the waterproof membrane 24, then melts the sealing wax on the surface of the first ignition wire 34, exposing and igniting the first ignition wire 34. The first ignition wire 34 then detonates the expansion body 32 connected to it. After the expansion body 32 explodes, the air pressure inside the shell 31 containing the expansion body 32 increases instantaneously, causing the shell 31 to explode. The extinguishing agent inside the shell 31 is then sprayed out to extinguish the fire. This ignition-type fire extinguishing bomb 3, triggered by the first ignition wire 34, is the first-stage fire extinguishing method. When the expansion body 32 explodes, it also ignites the second ignition wire 35 connected to it. This second ignition wire 35 can then ignite adjacent ignition-type fire extinguishing bombs 3, causing the extinguishing agent 33 within these bombs to be sprayed out to continue extinguishing the fire. This type of ignition-type fire extinguishing bomb 3 ignited by the second ignition wire 35 constitutes the second stage of fire extinguishing. When the ignition-type fire extinguishing bomb 3 that has achieved second-stage fire extinguishing continues to ignite the next ignition-type fire extinguishing bomb 3 via the second ignition wire, the third stage of fire extinguishing is achieved. Because every two adjacent ignition-type fire extinguishing bombs 3 are connected in series via the second ignition wire 35, the next ignition-type fire extinguishing bomb 3 can be continuously ignited, thus achieving multi-stage fire extinguishing.
[0061] Based on the working principle described above in Embodiment 1, it can be seen that Embodiment 1 has the following effects:
[0062] First, in this embodiment 1, the multi-stage fire extinguishing board for kitchens allows the device, installed on the front wall 5 of the stove 6, to extinguish a fire when it breaks out. This eliminates the need for manual firefighting and allows the device to extinguish the fire even when the stove 6 is unattended, thus improving safety. Furthermore, it eliminates the need for electronic components, preventing delays in fire extinguishing due to electronic component malfunctions and improving reliability.
[0063] Secondly, because multiple ignition-type fire extinguishing bombs 3 are set in the housing box 2, and each pair of adjacent ignition-type fire extinguishing bombs 3 are connected in series, once a certain ignition-type fire extinguishing bomb 3 is ignited by an open flame at the fire site, it can continuously ignite the next ignition-type fire extinguishing bomb 3 connected in series with it, thereby achieving multi-stage fire extinguishing, which is conducive to increasing the fire extinguishing range and fire extinguishing intensity, and improving the reliability of fire extinguishing.
[0064] Third, in the ignition-type fire extinguishing bomb 3 of this embodiment 1, the first ignition wire 34 is used to be directly ignited by the open flame at the fire site, and the second ignition wire 35 is used to ignite adjacent ignition-type fire extinguishing bombs 3, so that each ignition-type fire extinguishing bomb 3 can be directly ignited by the open flame at the fire site, and can also be indirectly ignited by adjacent ignition-type fire extinguishing bombs 3, which improves the flexibility of igniting the ignition-type fire extinguishing bomb 3, thereby improving the reliability of the ignition-type fire extinguishing bomb 3 in extinguishing fires in a timely manner.
[0065] Fourth, because the support frame 1 is installed on the wall 5 in front of the kitchen stove 6, it will not occupy the space on the surface of the stove 6, thus improving space utilization.
[0066] Example 2:
[0067] This embodiment 2 is an improvement upon embodiment 1:
[0068] The support frame 1 is also equipped with an angle adjustment structure, which is used to adjust the tilt angle of the container 2.
[0069] The use of an angle-adjustable structure allows adjustment of the tilt angle of the receiving box 2, thereby adjusting the tilt angle of the ignition-type fire extinguishing bomb 3 inside the receiving box 2, and consequently, adjusting the distance between the ignition-type fire extinguishing bomb 3 and the stove 6. The greater the tilt angle of the receiving box 2, the closer the ignition-type fire extinguishing bomb 3 is to the stove 6; conversely, the smaller the tilt angle of the receiving box 2, the farther the ignition-type fire extinguishing bomb 3 is from the stove 6. By adjusting the distance between the ignition-type fire extinguishing bomb 3 and the stove 6, it can accommodate cookware of different heights. For example, for frying pans, which are lower in height, the tilt angle of the ignition-type fire extinguishing bomb 3 can be adjusted to be greater, bringing the ignition-type fire extinguishing bomb 3 closer to the frying pan for more timely fire extinguishing, thus improving adaptability.
[0070] This embodiment 2 also provides a specific structure for the angle adjustment structure:
[0071] See Figure 3 and Figure 4 The angle adjustment structure includes an adjustment rod 4, which is made of stainless steel. The lower end of the adjustment rod 4 is rotatably connected to the top of the receiving box 2, and the upper end of the adjustment rod 4 is provided with a pin. The bottom of the receiving box 2 is rotatably connected to the bottom of the support frame 1. The upper part of the support frame 1 is provided with multiple insertion holes 11 along the vertical direction, and the pin is inserted into the insertion holes 11. In this embodiment 2, the pin is a bolt 41, and the bolt 41 is threadedly connected to the upper end of the adjustment rod 4.
[0072] The working principle of the angle adjustment structure in this embodiment 2 is as follows:
[0073] See Figure 4 In Figure (a), when the bolt 41, which acts as a pin, is inserted into the uppermost socket 11, the adjusting rod 4 and the receiving box 2 are both on a vertical line. At this time, the angle between the receiving box 2 and the wall 5 on the front side of the kitchen stove 6 is 0°.
[0074] See Figure 4 As shown in Figures (b) and (c), when the bolt 41, acting as a latch, is inserted into the lower-height socket 11, there is an angle between the adjusting rod 4 and the receiving box 2, causing the receiving box 2 to tilt towards the stove 6. The lower the height of the socket 11 into which the latch is inserted, the larger the angle between the receiving box 2 and the wall 5 in front of the kitchen stove 6, the greater the tilt of the receiving box 2, and the closer the ignition-type fire extinguishing bomb 3 inside the receiving box 2 is to the stove 6.
[0075] To change the insertion height of the pin: First, screw the bolt 41, which serves as the pin, away from the support frame 1, causing the pin to exit the current insertion hole 11. Then, move the upper end of the adjusting rod 4 vertically until the pin at the upper end of the adjusting rod 4 reaches the target height, then stop moving. Finally, screw the bolt 41, which serves as the pin, closer to the support frame 1, causing the pin to insert into the insertion hole 11 at the target height. This process changes the insertion height of the pin.
[0076] Based on the above working principle, it can be seen that the angle adjustment structure of this embodiment 2 has the following advantages:
[0077] In the angle adjustment structure of this embodiment 2, the tilt angle of the receiving box 2 can be changed simply by changing the insertion height of the pin. When the insertion height of the pin is lower, the tilt of the receiving box 2 is greater, and the ignition fire extinguishing bomb 3 inside the receiving box 2 is closer to the stove 6. This makes the structure simple, easy to adjust, and conducive to improving adjustment efficiency.
[0078] Example 3:
[0079] This embodiment 3 provides the specific structure of the receiving box 2:
[0080] See Figure 5The container 2 includes a body 21 and a lid 22. Both the body 21 and the lid 22 are made of stainless steel. The body 21 contains an ignition-type fire extinguishing bomb 3. The bottom of the body 21 is rotatably connected to the bottom of the support frame 1, and the top of the body 21 is rotatably connected to an adjusting rod 4. The lid 22 has an opening 221.
[0081] After the ignition-type fire extinguishing bomb 3 is loaded into the box body 21, the box cover 22 is then closed. The box cover 22 can be directly welded to the box body 21. After the box cover 22 is welded to the box body 21, the box cover 22 and the box body 21 are not easy to separate and need to be cut with a cutting machine.
[0082] In addition to welding methods, see Figure 5 Alternatively, screws 211 can be welded to the four corners of the box body 21, and through holes 222 can be made at the four corners of the box cover 22. When assembling the box body 21 and the box cover 22, align the through holes 222 on the box cover 22 with the screws 211 and fasten it onto the box body 21, so that the screws 211 pass through the through holes 222. Then, use nuts 212 to screw onto the screws 211, so that the box cover 22 is pressed tightly onto the box body 21 by the nuts 212, thus assembling the box cover 22 and the box body 21. When disassembling the box cover 22 and the box body 21, simply unscrew the nuts 212 from the screws 211 to separate the box body 21 and the box cover 22. This method of assembling the box cover 22 and the box body 21 using screws 211 and nuts 212 is convenient for disassembly and assembly, and convenient for replacing or inspecting the ignition-type fire extinguishing bombs 3 inside the box body 21, improving the ease of use.
[0083] In addition, see Figure 5 A sealing ring 23 is provided between the box body 21 and the box cover 22. The four corners of the sealing ring 23 are provided with clearance holes 231, which are used for the screw 211 to pass through. The sealing ring 23 can improve the sealing effect between the box body 21 and the box cover 22, which is conducive to improving the moisture-proof effect of the first ignition wire 34 and improving the reliability of the ignition-type fire extinguishing bomb 3.
