Description

Technical Field

[0001] This invention relates to the field of fire extinguisher technology, and in particular to a high-safety fire extinguisher. Background Technology

[0002] Fire extinguishers, as basic fire-fighting equipment, are widely used in homes, offices, and various public facilities. Their main function is to extinguish initial fires by releasing the extinguishing agent inside, thereby reducing the risk of fire spreading. Traditional dry powder fire extinguishers occupy a large market share due to their low cost and wide applicability. However, with social development and technological progress, people have put forward higher requirements for the safety, ease of use, and effectiveness of fire extinguishers.

[0003] While traditional dry powder fire extinguishers play a vital role in many situations, they also reveal some shortcomings in practical use: First, to ensure the dry powder extinguishing agent is evenly distributed and effectively sprayed, users need to shake the extinguisher thoroughly before operation. This process is both time-consuming and strenuous for people with less strength (such as children, the elderly, or those who are physically weak), and insufficient shaking will directly affect the performance of the extinguisher. Second, the nozzle length of existing fire extinguishers is relatively short, which limits the user's ability to accurately strike the fire source from a safe distance. If the user attempts to spray dry powder from a greater distance, it is difficult to ensure that the extinguishing agent accurately covers the ignition point. Conversely, approaching the fire source to improve spray accuracy increases the risk of personal injury. Summary of the Invention

[0004] In view of this, the present invention provides a high-safety fire extinguisher that solves the problems of traditional dry powder fire extinguishers, which require users to shake the extinguisher to mix the dry powder, which is time-consuming and laborious. In addition, the nozzle length of existing fire extinguishers is relatively short, which limits the user's ability to accurately strike the fire source from a safe distance.

[0005] Technical Solution: A high-safety fire extinguisher includes a cylinder and a connecting pipe. The top of the cylinder is connected to the connecting pipe, and a movable rod is slidably mounted on the connecting pipe. A lifting mechanism is installed on the connecting pipe to control the movement of the movable rod. A sealing block is connected to the movable rod and is located inside the connecting pipe. A contact frame is connected to the bottom of the sealing block. A sealing mechanism is installed inside the connecting pipe. Both the sealing block and the sealing mechanism are used to block the inside of the connecting pipe. A siphon tube is installed inside the connecting pipe to draw out the extinguishing agent from the cylinder. A rotating tube is rotatably mounted on the siphon tube, and a rotating mechanism is installed on the siphon tube to drive the rotating tube to rotate. A rotating plate is rotatably mounted on the side of the rotating tube to agitate the extinguishing agent in the cylinder. A first torsion spring is connected between the rotating plate and the rotating tube. A locking mechanism is installed inside the siphon tube to lock the rotating tube. A flexible hose is connected to the connecting pipe, and a fixed tube is connected to the flexible hose. A telescopic tube is slidably mounted inside the fixed tube.

[0006] Furthermore, it is particularly preferred that the lifting mechanism includes a handle, a pressure handle, a pin, a plastic locking rod, and a first spring. The handle is installed on the side of the connecting pipe, the pressure handle is rotatably installed on the handle, the movable rod is movably connected to the pressure handle, the pin is slidably arranged between the pressure handle and the handle, the plastic locking rod is installed at the end of the pin, and the first spring is connected between the movable rod and the inside of the connecting pipe.

[0007] Furthermore, it is particularly preferred that the sealing mechanism includes a hollow ring, a second spring, and a closing ring. The hollow ring is disposed inside the connecting pipe, one end of the second spring is connected to the hollow ring, and the other end of the second spring is connected to the closing ring. The closing ring is used to seal the inside of the connecting pipe.

[0008] Furthermore, it is particularly preferred that the rotating mechanism includes a fixed ring, a rotating ring, and a spring. The fixed ring is installed on the siphon tube, and the rotating ring is also rotatably installed on the siphon tube at intervals. A spring connects two adjacent rotating rings, a spring connects the rotating ring and the fixed ring, and a spring connects the rotating ring and the rotating tube.

[0009] Furthermore, it is particularly preferred that the locking mechanism includes a ratchet ring, a bracket, a connecting rod, and a first toothed plate. The ratchet ring is installed inside the rotating tube, the bracket is provided inside the siphon tube, the connecting rod is slidably mounted on the bracket, the end of the connecting rod is connected to the bottom of the contact frame, and the first toothed plate is connected to the connecting rod, which engages with the ratchet ring.

[0010] In addition, it is particularly preferred that the device also includes a connecting ring and a rubber limiting plate. The connecting ring is installed on the bottle body, and the rubber limiting plate is provided on the connecting ring. The rubber limiting plate is used to limit the fixing tube.

[0011] Furthermore, it is particularly preferred that the tube also includes a sleeve, which is slidably disposed on the fixing tube and extends to the connecting tube to fix the fixing tube.

[0012] Furthermore, it is particularly preferred that the device also includes a locking mechanism, which includes a ratchet, a second toothed plate, and a second torsion spring. The ratchet is connected to the pressure handle, and the second toothed plate is rotatably mounted on the handle. The second toothed plate meshes with the ratchet, and the second torsion spring is installed between the second toothed plate and the handle.

[0013] The beneficial effects are as follows: 1. By setting up a linkage structure between the rotating mechanism and the locking mechanism, the rotating plate is automatically driven to stir the extinguishing agent in the bottle after the handle is pressed. There is no need to manually shake the fire extinguisher in advance, which solves the problem that traditional dry powder fire extinguishers must be shaken vigorously before use. It is especially suitable for people with less strength, improving the ease of use and popularity of fire extinguishers. In addition, the fire extinguisher is equipped with a hose, a fixed tube and a telescopic tube, which extends the spray distance, allowing users to accurately strike the fire source from a safe distance, avoiding personal injury caused by getting close to the fire source and improving safety.

[0014] 2. This invention allows for control of the spray intensity by gradually pressing the handle. In the initial stage, a small flow rate is sprayed to extinguish initial fires, while continued pressing increases the spray volume to deal with larger fires, thus enhancing the applicability and flexibility of the fire extinguisher.

[0015] 3. The locking mechanism of the present invention can automatically lock after pressing the handle, so that the user can maintain the spraying state without continuous force, reducing fatigue and improving emergency response capability. Attached Figure Description

[0028] Example: A high-safety fire extinguisher, see [link / reference] Figures 1-9As shown, the device includes a bottle body 1 and a connecting pipe 2. The bottle body 1 is used to store extinguishing agent under high pressure. The top of the bottle body 1 is connected to the connecting pipe 2, and the lower front of the connecting pipe 2 is connected to a pressure gauge for detecting the pressure inside the bottle body 1. It also includes a movable rod 3, a lifting mechanism, a sealing block 5, a contact frame 6, a sealing mechanism, a siphon tube 8, a rotating tube 9, a rotating mechanism, a rotating plate 11, a first torsion spring 12, a locking mechanism, a hose 14, a fixed tube 15, and a telescopic tube 16. The movable rod 3 is slidably mounted on the connecting pipe 2. A lifting mechanism is installed on the connecting pipe 2 to control the lifting and lowering of the movable rod 3. The bottom of the movable rod 3 is connected to the sealing block 5, which is located inside the connecting pipe 2. The bottom of the sealing block 5 is connected to the contact frame 6. A sealing mechanism is provided inside the connecting pipe 2. Both the sealing block 5 and the sealing mechanism are used to block the inside of the connecting pipe 2. A siphon tube 8 is provided on the lower side of the connecting pipe 2. The siphon tube 8 is used to draw out the extinguishing agent in the bottle 1. A rotating tube 9 is rotatably installed on the lower outer side of the siphon tube 8. A rotating mechanism is installed on the siphon tube 8. The rotating mechanism is used to drive the rotating tube 9 to rotate. Six rotating plates 11 are rotatably arranged on the side of the rotating tube 9 at intervals. The rotating plates 11 are used to stir the extinguishing agent in the bottle 1. A first torsion spring 12 is connected between the rotating plates 11 and the rotating tube 9. A locking mechanism is provided inside the siphon tube 8. The locking mechanism is used to lock the rotating tube 9. A hose 14 is connected to the connecting pipe 2. A fixed tube 15 is connected to the hose 14. A telescopic tube 16 is slidably arranged inside the fixed tube 15.

[0029] See Figures 1-3 As shown, the lifting mechanism includes a handle 401, a pressure handle 402, a pin 403, a plastic locking rod 404, and a first spring 405; the handle 401 is installed on the upper right side of the connecting pipe 2; the pressure handle 402 is rotatably installed on the handle 401, and two elliptical holes are opened on the left side of the pressure handle 402, the upper end of the movable rod 3 moves in the elliptical holes of the pressure handle 402; the pin 403 is slidably arranged between the pressure handle 402 and the handle 401; the plastic locking rod 404 is installed on the rear side of the pin 403, and the plastic locking rod 404 is used to limit the pin 403 to prevent the pin 403 from falling off; the first spring 405 is connected between the movable rod 3 and the top of the inner part of the connecting pipe 2.

[0030] See Figure 2 and Figure 4 As shown, the sealing mechanism includes a hollow ring 701, a second spring 702, and a closing ring 703; a hollow ring 701 is provided inside the connecting pipe 2; the upper end of the second spring 702 is connected to the hollow ring 701, and the lower end of the second spring 702 is connected to the closing ring 703. The closing ring 703 is used to seal the inside of the connecting pipe 2, and the sealing block 5 is in contact with the inside of the closing ring 703. The sealing block 5 is used to seal the inside of the closing ring 703, and there is a certain distance between the top surface of the contact frame 6 and the bottom surface of the closing ring 703.

[0031] See Figure 5 and Figure 6 As shown, the rotating mechanism includes a fixed ring 1001, a rotating ring 1002, and a spring 1003; the fixed ring 1001 is installed in the middle of the siphon tube 8; three rotating rings 1002 are rotatably installed at intervals on the lower side of the siphon tube 8, the three rotating rings 1002 are distributed in an upper, middle and lower manner, and all three rotating rings 1002 are located above the rotating tube 9. A spring 1003 is connected between two adjacent rotating rings 1002, and a spring 1003 is also connected between the upper rotating ring 1002 and the fixed ring 1001, and a spring 1003 is also connected between the lower rotating ring 1002 and the rotating tube 9. The number of springs 1003 is four.

[0032] See Figure 7 and Figure 8 As shown, the locking mechanism includes a ratchet ring 1301, a bracket 1302, a connecting rod 1303, and a first toothed plate 1304; the ratchet ring 1301 is installed on the lower side of the rotating tube 9; the bracket 1302 is provided on the lower side of the siphon tube 8; the connecting rod 1303 is slidably arranged on the bracket 1302, the end of the connecting rod 1303 is connected to the bottom of the contact frame 6, and the lower side of the connecting rod 1303 is connected to the first toothed plate 1304, which meshes with the ratchet ring 1301.

[0033] In the initial state, all four mainsprings 1003 are in a deformed state, and the first toothed plate 1304 engages with the ratchet ring 1301, thereby using the first toothed plate 1304 to lock the ratchet ring 1301, the rotating tube 9, the mainsprings 1003 and the rotating ring 1002. In use, first grasp the handle 401 and lift it up, then pull the pin 403 out, causing the pin 403 to move the plastic latch 404. When the plastic latch 404 contacts the handle 401, the handle 401 will apply pressure to the plastic latch 404, thereby breaking the plastic latch 404 and releasing the plastic latch 404 from the pin 403. After the pin 403 is pulled out, pull the telescopic tube 16 out from the fixed tube 15, then grasp the fixed tube 15 and adjust its position until the telescopic tube 16 on the fixed tube 15 is close to the fire source. Then, use the hand holding the handle 401 to press the lever 402 to rotate, causing the lever 402 to move the movable rod 3 upward, and the first spring 405... Compression causes the movable rod 3 to move the sealing block 5, contact frame 6, connecting rod 1303, and first toothed plate 1304 upwards. When the first toothed plate 1304 separates from the ratchet ring 1301, it releases the lock on the ratchet ring 1301, rotating tube 9, spring 1003, and rotating ring 1002. At this time, the spring 1003 returns to its original state and drives the rotating ring 1002, rotating tube 9, and ratchet ring 1301 to rotate at high speed and gradually decelerate to stop. When the rotating tube 9 rotates, it drives the rotating plate 11 to swing, causing the rotating plate 11 to rotate under the action of centrifugal force. The first torsion spring 12 deforms, causing the rotating plate 11 to move against the inside of the bottle body 1. The extinguishing agent is stirred to automatically mix the extinguishing agent in the cylinder 1. As the rotating tube 9 gradually decelerates to a stop, the centrifugal force on the rotating plate 11 also gradually decreases. During this period, the first torsion spring 12 gradually returns to its original state, and the first torsion spring 12 also drives the rotating plate 11 to gradually reverse and reset. When the sealing block 5 separates from the inner side of the sealing ring 703, a gap will appear between the sealing block 5 and the inner side of the sealing ring 703. At this time, the extinguishing agent in the cylinder 1 is affected by the high pressure state, and the extinguishing agent will be sprayed out through the siphon tube 8, the gap between the sealing block 5 and the sealing ring 703, the connecting tube 2, the hose 14, the fixed tube 15, and the telescopic tube 16. In this way, the extinguishing agent can be sprayed out to extinguish the fire, and the fire can also be extinguished through the telescopic tube. 16. When the extinguishing agent is aimed at the fire source at close range, it can accurately strike the fire source. If the fire is large, the user can press the handle 402 to continue to rotate, so that the handle 402 continues to drive the movable rod 3 to move upward. This causes the movable rod 3 to continue to drive the sealing block 5, contact frame 6, connecting rod 1303 and first toothed plate 1304 to move upward. When the contact frame 6 contacts the sealing ring 703, the contact frame 6 will drive the sealing ring 703 to move upward. The second spring 702 is compressed, so that the sealing ring 703 no longer blocks the inside of the connecting pipe 2. In this way, the flow of extinguishing agent in the connecting pipe 2 can be increased, so that the user can use different intensities of extinguishing agent to spray when facing different types and sizes of fires. After use, release the pressure handle 402. At this time, the first spring 405 returns to its original state, and the first spring 405 drives the movable rod 3 to move downwards to reset, causing the movable rod 3 to drive the pressure handle 402 to reverse and reset. At the same time, the movable rod 3 drives the sealing block 5, contact frame 6, connecting rod 1303 and first toothed plate 1304 to move downwards to reset. When the contact frame 6 separates from the sealing ring 703, the second spring 702 returns to its original state, and the second spring 702 drives the sealing ring 703 to move downwards to reset, causing the sealing ring 703 to revert to its original position. The inner side of the connecting tube 2 is sealed. When the sealing block 5 contacts the inner side of the sealing ring 703, the sealing block 5 will re-seal the inner side of the sealing ring 703. When the first toothed plate 1304 engages with the ratchet ring 1301, the first toothed plate 1304 will re-lock the ratchet ring 1301, the rotating tube 9, the spring 1003 and the rotating ring 1002. Then, the fixing tube 15 is released, and the telescopic tube 16 is pushed back into the fixing tube 15. After that, the bottle body 1 is put down, and the handle 401 is released.

[0034] See Figure 10 As shown, it also includes a connecting ring 17 and a rubber limiting plate 18; a connecting ring 17 is installed on the lower outer side of the bottle body 1; a rubber limiting plate 18 is provided on the left side of the connecting ring 17, and the fixing tube 15 is inserted into the rubber limiting plate 18 so that the rubber limiting plate 18 limits the fixing tube 15.

[0035] By setting the connecting ring 17 and the rubber limiting plate 18, the rubber limiting plate 18 can limit the fixed tube 15, so that the fire extinguisher can be transported or stored, avoiding the fixed tube 15 from swinging around and affecting the transport or storage. At the same time, it can also prevent the fixed tube 15 from being damaged by collision or squeezing. When in use, the fixed tube 15 can be pulled out from the rubber limiting plate 18, so that the rubber limiting plate 18 releases the limitation on the fixed tube 15. After use, the fixed tube 15 can be inserted into the rubber limiting plate 18, so that the rubber limiting plate 18 can limit the fixed tube 15 again.

[0036] See Figure 10 As shown, it also includes a sleeve 19; the sleeve 19 is slidably disposed on the fixing tube 15, and the sleeve 19 is used to extend to the connecting tube 2 to fix the fixing tube 15.

[0037] By setting the sleeve 19, when the telescopic tube 16 on the fixed tube 15 is close to the fire source, the sleeve 19 can be pulled onto the connecting tube 2, thereby fixing the fixed tube 15 onto the connecting tube 2 using the sleeve 19. In this way, the orientation of the fixed tube 15 can be automatically stabilized, so that the user no longer needs to hold the fixed tube 15 to stabilize it. After use, the sleeve 19 can be pushed back onto the fixed tube 15, so that the sleeve 19 can be removed from the connecting tube 2.

[0038] See Figure 11As shown, it also includes a locking mechanism, which includes a ratchet 20, a second toothed plate 21, and a second torsion spring 22; the ratchet 20 is connected to the front side of the pressure handle 402; the second toothed plate 21 is rotatably mounted on the front side of the handle 401, and the second toothed plate 21 meshes with the ratchet 20; the second torsion spring 22 is installed between the second toothed plate 21 and the handle 401.

[0039] By setting up a locking mechanism, when the user presses and rotates the handle 402, the handle 402 drives the ratchet 20 to rotate. During this rotation, the ratchet 20 presses against the second toothed plate 21, causing the second torsion spring 22 to deform. When the user stops pressing and rotating the handle 402, the handle 402 drives the ratchet 20 to stop rotating. At this time, the second torsion spring 22 returns to its original state, causing the second toothed plate 21 to reverse and reset, thus locking the ratchet 20. In this way, the user can release the handle 402. There is no need to hold down the lever 402 continuously, making it convenient for the user. After use, the second toothed plate 21 is rotated, and the second torsion spring 22 deforms, causing the second toothed plate 21 to separate from the ratchet 20. This allows the second toothed plate 21 to release the ratchet 20. Then, when the lever 402 is reversed and reset, the lever 402 will drive the ratchet 20 to reverse and reset. Then, the second toothed plate 21 is released, allowing the second torsion spring 22 to return to its original state. The second torsion spring 22 will drive the second toothed plate 21 to reverse and reset, allowing the second toothed plate 21 to re-engage with the ratchet 20.
