Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, and more particularly to a sheet-type fire extinguisher with fire extinguishing agent inside. Background Art

[0002] In existing fire extinguisher technology, most fire extinguishers require users to hold them in their hands for operation. This operation method poses certain safety hazards. When facing a large fire, users need to get close to the fire source, which may cause burns to the human body. In addition, traditional fire extinguishers are large in size and inconvenient to carry, especially in confined spaces or emergency situations. This size and weight may become an obstacle to rapid response and operation.

[0003] In order to solve these problems, a new type of sheet fire extinguisher has appeared on the market. This fire extinguisher contains fire extinguishing agent and is activated by a thermal element. When the external temperature exceeds the set value, the thermal element will rupture and then prompt other components to release fire extinguishing foam. However, this design has some problems. First, if there are no proper protection measures, the thermal element may be accidentally activated due to high temperature during storage or transportation, resulting in waste of fire extinguishing agent and potential damage. Although some devices have thermal insulation components on the outside to protect the thermal elements, these thermal insulation components are often difficult to disassemble and require professional tools and expertise, which will delay the use of the fire extinguisher in an emergency.

[0004] In addition, some fire extinguishers are designed with quick-disassembly and assembly shell insulation components, but these designs are often too simple and lack stability. During transportation, due to bumps and collisions, these insulation components may accidentally loosen or fall off, causing the heat-sensitive components to lose protection and unable to work normally when needed.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides a sheet-type fire extinguisher with internal fire extinguishing agent, which has the following beneficial effects:

[0018] 1. The design of the fire extinguishing device enables it to be quickly activated when needed and effectively extinguish the fire. Through the detachable connection of the upper cover and the lower shell, as well as the internal movable frame and push spring and other components, when the fire extinguishing device is thrown into the center of the fire source, the thermal explosion tube will rupture due to high temperature, releasing the push spring, pushing the movable frame to move, so that the puncture cone pierces the protective layer and the storage bag, releasing aluminum sulfate solution and sodium bicarbonate solution. The mixing reaction of these two solutions quickly generates solid aluminum hydroxide precipitate and gaseous carbon dioxide, forming high-pressure foam and quickly ejected through the through hole to achieve rapid fire extinguishing. The setting of the isolation layer ensures the safety of the storage bag when not in use, prevents accidental mixing and reaction of the solutions, and ensures the long-term storage stability of the fire extinguishing device. This optimized structure is smaller in size, easy to store and carry, and more convenient to use.

[0019] 2. The design of the quick-release device significantly improves the operational convenience and response speed of the fire extinguisher. Through the cooperation of components such as the rotating sleeve, the limiting assembly and the connecting block, the user can quickly remove the fire extinguishing device from the insulation component in an emergency. Through simple operation, the connection between the splicing rod and the splicing sleeve is released, allowing the top plate to push the splicing rod to promote the separation of the two. This design enables the fire extinguishing device to be removed within seconds, greatly shortening the fire extinguishing preparation time and improving the efficiency of fire response.

[0020] 3. The self-locking mechanism ensures the safety of the fire extinguisher when not in use, preventing accidental triggering and mis-activation of the fire extinguishing device. Through the interaction of components such as the adapter rod, rotating sleeve, limiting sleeve and spring, the self-locking mechanism forms a stable locked state after the fire extinguishing device is assembled. The setting of components such as the adapter spring and connecting spring prevents accidental rotation of the control sleeve, thereby ensuring the safety of the fire extinguishing device during transportation and storage. The structural stability of this self-locking mechanism effectively eliminates the risk of accidental unlocking of the fire extinguisher during bumps or collisions, ensures the thermal insulation protection of the fire extinguishing device, and ensures its reliable operation at critical moments.

[0035] An adapter spring 29 is sleeved on the outer side of the adapter rod 14 . One end of the adapter spring 29 is connected to the limiting sleeve 20 , and the other end of the adapter spring 29 is in contact connection with the rotating sleeve 16 .

[0036] In this embodiment, when the device is stored or transported, since the top cover 2 and the bottom shell 1 are made of heat-insulating material, the external temperature can be effectively prevented from affecting the fire extinguishing device when not in use. When the device needs to be used, the rotating sleeve 16 is first rotated. The rotating sleeve 16 will drive the return block 19 connected to one side to rotate, and then the return block 19 will cooperate with the connecting block 17 to squeeze the spring 18. At the same time, the rotating sleeve 16 will drive the adapter hole 15 to rotate. When the spring 18 is squeezed to the limit, the position of the adapter hole 15 corresponds to the position of the adapter rod 14, and then the limiting sleeve 20 is slid. The limiting sleeve 20 will drive the adapter rod 14 to slide, and then the adapter rod 14 will pass through the adapter hole 15. At the same time, the limiting sleeve 20 will cooperate with the rotating sleeve 16 to adjust the adapter provided on the outside of the adapter rod 14. The matching spring 29 is squeezed, and when the matching spring 29 is squeezed to the limit, the outer side of the limiting rod 26 loses the limit of the limiting sleeve 20, and then the control sleeve 10 is rotated, and the control sleeve 10 drives the limiting rod 26 to move, and then the side wall of the limiting groove 27 will squeeze one end of the limiting rod 26. Due to the rounded structure treatment at the end of the limiting rod 26 and the edge of the limiting groove 27, then one end of the limiting rod 26 may slide out of the limiting groove 27, and then the other end of the limiting rod 26 will drive the connecting spring 28 to stretch, and at the same time, the control sleeve 10 will drive the fixed block 9 to move through the fixed plate 8 connected on one side. Due to the spiral structure design of the guide groove 13 and the adaptability of the fixed block 9, then the fixed block 9 will slide in the guide groove 13, and then the movable sleeve 12 will drive the movable groove 5 to slide, and then the movable The inner wall of the movable groove 5 will gradually push the rotating plate 6, so that the rotating plate 6 drives the clamping plate 22 to rotate along the rotating shaft 7, and then the clamping plate 22 will gradually rotate out of the clamping groove 23 and gradually enter the fixed groove 4. When the clamping plate 22 is completely disengaged from the clamping groove 23, the top spring 24 will push the top plate 25 to return to its original position, and then the top plate 25 will push the splicing rod 3, prompting the splicing rod 3 and the splicing sleeve 11 to be separated, and then the splicing rod 3 can be pulled out to achieve complete separation of the splicing rod 3 and the splicing sleeve 11, and then the top cover 2 can be opened to take out the fire extinguishing device for use. When the fire extinguishing device needs to be transported and stored, the fire extinguishing device is first placed inside the lower shell 31, and then the top cover 2 is covered and attached to the bottom shell 1, and then one end of the splicing rod 3 passes through the mounting hole from one side of the top cover 2. Then the splicing sleeve 11 is sleeved to the outside of the splicing rod 3 from the other side, and then the splicing rod 3 will push the top plate 25, so that the top plate 25 squeezes the top spring 24 again. When the top spring 24 is squeezed to the limit, the control sleeve 10 is rotated in the opposite direction, so that the control sleeve 10 drives the fixed plate 8 and the fixed block 9 to rotate, and then the fixed block 9 and the guide groove 13 cooperate to drive the movable sleeve 12 to reset, and then the movable sleeve 12 will drive the movable groove 5 to reset, and then the other side of the inner wall of the movable groove 5 will push the rotating plate 6 from the other side, and then the rotating plate 6 will drive the clamping plate 22 to rotate and reset along the rotating shaft 7, and then the clamping plate 22 will rotate out of the fixed groove 4 and enter the clamping groove 23. When the movable sleeve 12 is completely reset, the clamping plate 22 forms a clamping relationship with the clamping groove 23 again.And make the splicing sleeve 11 and the pressing plate 21 set at one end of the splicing plate fix the top cover 2 and the bottom shell 1 together, at this time the connecting spring 28 will drive the limiting rod 26 to insert into the original limiting groove 27, and then release the limiting sleeve 20, the adapting spring 29 pushes the limiting sleeve 20 to slide and reset, and then the limiting sleeve 20 will drive the adapting rod 14 to slide and reset, when the adapting spring 29 is completely reset, the adapting rod 14 no longer limits the rotating sleeve 16 through the adapting hole 15, and then the spring 18 will push the return block 19 to reset, and then return The block 19 will drive the adapter hole 15 to reset by rotating the sleeve 16, so that the adapter hole 15 moves to a position that does not correspond to the adapter rod 14. The adapter rod 14 then limits the limit sleeve 20. The inner wall of the limit sleeve 20 then limits the outer end of the limit rod 26. The limit rod 26 then cooperates with the limit groove 27 to limit the control sleeve 10, preventing the control sleeve 10 from rotating. This ensures structural stability and eliminates the possibility of accidental unlocking, thereby achieving thermal insulation protection for the fire extinguishing device and preventing the fire extinguishing device from being accidentally activated.

[0037] See also Figure 1 and Figure 2 As an implementation method of the fire extinguishing device: the fire extinguishing device includes an upper cover 30, a lower shell 31, a protective layer 32, an isolation layer 33, a through hole 34, a puncture cone 35, a storage bag 36 and a thermal explosion tube 37. The upper cover 30 is detachably connected to the lower shell 31 through a thread, multiple through holes 34 are opened on the side wall of the lower shell 31, the puncture cone 35 is fixedly set inside the lower shell 31, the storage bag 36 is set on the inner side of the lower shell 31, the thermal explosion tube 37 is set on the inner side of the lower shell 31, the isolation layer 33 is set in the protective layer 32, and the protective layer 32 is wrapped around the outside of the storage bag 36.

[0038] A movable frame 38 is provided on one side of the storage bag 36 . A push spring 39 is connected to one side of the movable frame 38 . The other end of the push spring 39 is connected to the inner side of the upper cover 30 .

[0039] More specifically, when the device needs to be used, the top cover 2 is first opened, and the internal fire extinguishing device is turned upside down and taken out, and then the fire extinguishing device as a whole is thrown as far as possible to the center of the fire source. When the external temperature is too high, the thermal explosion tube 37 ruptures, and then the movable frame 38 loses its support, and then the push spring 39 is no longer limited, and then the push spring 39 will push the movable frame 38 to move, and then the movable frame 38 will drive the protective layer 32 and the storage bag 36 set inside to move, and then the puncture cone 35 set inside the lower shell 31 will puncture the protective layer 32, and then puncture the two storage bags 36 set inside the protective layer 32. 6. The two storage bags 36 respectively store aluminum sulfate solution and sodium bicarbonate solution. When the two storage bags 36 are punctured, the solutions stored inside flow out and mix. Then, the aluminum ions and bicarbonate ions in the solution undergo double hydrolysis to generate solid aluminum hydroxide precipitate and gaseous carbon dioxide. Since the carbon dioxide is generated very quickly, high pressure is formed in the solution, causing foam to be generated and quickly ejected from the through hole 34 opened on the side wall of the lower shell 31, thereby realizing the fire extinguishing function. The setting of the isolation layer 33 can prevent the storage bag 36 from being accidentally damaged when not in use, causing the two solutions to mix and react.

[0040] In summary, when the entire device is in use or running: when the device is stored or transported, since the top cover 2 and the bottom shell 1 are made of heat-insulating material, it can effectively prevent the external temperature from affecting the fire extinguishing device when not in use. When the device needs to be used, first rotate the rotating sleeve 16. The rotating sleeve 16 will drive the return block 19 connected to one side to rotate, and then the return block 19 will cooperate with the connecting block 17 to squeeze the spring 18. At the same time, the rotating sleeve 16 will drive the adapter hole 15 to rotate. When the spring 18 is squeezed to the limit, the position of the adapter hole 15 corresponds to the position of the adapter rod 14, and then the limiting sleeve 20 is slid. The limiting sleeve 20 will drive the adapter rod 14 to slide, and then the adapter rod 14 will pass through the adapter hole 15, and the limiting sleeve 20 will cooperate with the rotating sleeve 16 The adapter spring 29 sleeved on the outside of the adapter rod 14 is squeezed. When the adapter spring 29 is squeezed to the limit, the outside of the limiting rod 26 loses the limit of the limiting sleeve 20, and then the control sleeve 10 is rotated. The control sleeve 10 drives the limiting rod 26 to move, and then the side wall of the limiting groove 27 will squeeze one end of the limiting rod 26. Due to the rounded structure treatment at the end of the limiting rod 26 and the edge of the limiting groove 27, then one end of the limiting rod 26 may slide out of the limiting groove 27, and then the other end of the limiting rod 26 will drive the connecting spring 28 to stretch, and at the same time, the control sleeve 10 will drive the fixing block 9 to move through the fixing plate 8 connected on one side. Due to the spiral structure design of the guide groove 13 and the adaptability of the fixing block 9, then the fixing block 9 will slide in the guide groove 13, and then the movable sleeve 1 2 will drive the movable groove 5 to slide, and then the inner wall of the movable groove 5 will gradually push the rotating plate 6, so that the rotating plate 6 drives the clamping plate 22 to rotate along the rotating shaft 7, and then the clamping plate 22 will gradually rotate out of the clamping groove 23 and gradually enter the fixed groove 4. When the clamping plate 22 is completely disengaged from the clamping groove 23, the top spring 24 will push the top plate 25 to reset, and then the top plate 25 will push the splicing rod 3, prompting the splicing rod 3 and the splicing sleeve 11 to be separated, and then the splicing rod 3 can be pulled out to achieve complete separation of the splicing rod 3 and the splicing sleeve 11, and then open the top cover 2 to take out the fire extinguishing device for use. When the fire extinguishing device needs to be transported and stored, first place the fire extinguishing device inside the lower shell 31, then cover the top cover 2 with the bottom shell 1, and then make the splicing rod 3 and the splicing sleeve 11 separate. One end of the connecting rod 3 passes through the mounting hole from one side of the top cover 2, and then the splicing sleeve 11 is sleeved on the outside of the splicing rod 3 from the other side, and then the splicing rod 3 will push the top plate 25, so that the top plate 25 squeezes the top spring 24 again. When the top spring 24 is squeezed to the limit, the control sleeve 10 is rotated in the opposite direction, so that the control sleeve 10 drives the fixed plate 8 and the fixed block 9 to rotate, and then the fixed block 9 cooperates with the guide groove 13 to drive the movable sleeve 12 to reset, and then the movable sleeve 12 will drive the movable groove 5 to reset, and then the other side of the inner wall of the movable groove 5 will push the rotating plate 6 from the other side, and then the rotating plate 6 will drive the clamping plate 22 to rotate and reset along the rotating shaft 7, and then the clamping plate 22 will rotate out of the fixed groove 4 and enter the clamping groove 23. When the movable sleeve 12 is completely reset,The clamping plate 22 re-engages with the clamping groove 23, and the splicing sleeve 11 and the pressing plate 21 set at one end of the splicing plate fix the top cover 2 and the bottom shell 1 together. At this time, the connecting spring 28 drives the limiting rod 26 to be inserted into the original limiting groove 27, and then the limiting sleeve 20 is released. The adapting spring 29 pushes the limiting sleeve 20 to slide back, and then the limiting sleeve 20 drives the adapting rod 14 to slide back. When the adapting spring 29 is fully reset, the adapting rod 14 no longer limits the rotating sleeve 16 through the adapting hole 15, and then the spring 18 pushes back The travel block 19 is reset, and then the return block 19 drives the adapter hole 15 to reset through the rotating sleeve 16, so that the adapter hole 15 moves to a position that does not correspond to the adapter rod 14. The adapter rod 14 then limits the limiting sleeve 20, and then the inner wall of the limiting sleeve 20 again limits the outer end of the limiting rod 26. Then the limiting rod 26 cooperates with the limiting groove 27 to limit the control sleeve 10, preventing the control sleeve 10 from rotating, thereby ensuring structural stability and eliminating the possibility of accidental unlocking, thereby achieving thermal insulation protection for the fire extinguishing device and preventing the fire extinguishing device from being accidentally activated.

[0041] When the device needs to be used, first open the top cover 2, then take out the internal fire extinguishing device upside down, and then throw the fire extinguishing device as a whole as possible to the center of the fire source. When the external temperature is too high, the thermal explosion tube 37 ruptures, and then the movable frame 38 loses its support, and then the push spring 39 is no longer limited, and then the push spring 39 will push the movable frame 38 to move, and then the movable frame 38 will drive the protective layer 32 and the storage bag 36 set inside to move, and then the puncture cone 35 set inside the lower shell 31 will puncture the protective layer 32, and then puncture the two storage bags 36 set inside the protective layer 32, and the two storage bags 36 are set inside the protective layer 32. Each storage bag 36 stores aluminum sulfate solution and sodium bicarbonate solution respectively. When the two storage bags 36 are punctured, the solutions stored inside flow out and mix. Then, the aluminum ions and bicarbonate ions in the solution undergo double hydrolysis to generate solid aluminum hydroxide precipitate and gaseous carbon dioxide. Since the carbon dioxide is generated very quickly, high pressure is formed in the solution, causing foam to be generated and quickly ejected from the through hole 34 opened on the side wall of the lower shell 31, thereby realizing the fire extinguishing function. The setting of the isolation layer 33 can prevent the storage bag 36 from being accidentally damaged when not in use, causing the two solutions to mix and react.

[0042] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
