Description

Technical Field

[0001] This invention relates to the field of fire extinguisher technology, specifically to a portable high-pressure water mist fire extinguisher. Background Technology

[0002] High-pressure water mist fire extinguishing technology boasts advantages such as using water as the extinguishing medium, being environmentally friendly and residue-free, having excellent cooling and smoke suppression effects, and being suitable for extinguishing fires in various scenarios including electrical fires, lithium battery fires, and solid fires. Compared to traditional dry powder fire extinguishers and carbon dioxide fire extinguishers, it produces no dust pollution, causes no equipment corrosion, and is harmless to the human body, making it the mainstream technology for emergency fire extinguishing in civilian, household, vehicle-mounted, and small commercial settings. Among them, portable high-pressure water mist fire extinguishers, due to their small size, portability, and ease of operation, are widely used in confined, close-range emergency fire extinguishing scenarios such as homes, private cars, offices, precision instrument rooms, and new energy vehicles, possessing extremely high practical value and market prospects.

[0003] Most existing portable high-pressure water mist fire extinguishers adopt a pressurized mechanical structure, relying on pre-pressurized gas inside the cylinder to compress the extinguishing medium, which is then atomized and sprayed through a fixed nozzle to achieve fire extinguishing.

[0004] The inventors of this application discovered in their research that the core defect of the above-mentioned prior art is that: the nozzles of existing products are mostly fixed structures, which can only output water mist of a single particle size. They cannot adjust the spray state according to the distance to the fire and the size of the fire. When extinguishing fires at close range, the large-particle water mist can easily cause water accumulation and damage to the equipment. When extinguishing fires at long distance, the atomized particles are large and the range is insufficient, making it difficult to break through the heat radiation area of ​​the fire and resulting in low fire extinguishing efficiency. Summary of the Invention

[0005] This invention provides a portable high-pressure water mist fire extinguisher, which solves the problem that the nozzles in the prior art are mostly fixed structures, which can only output water mist of a single particle size and cannot adjust the spray state according to the distance of the fire and the size of the fire. It realizes the effect of adjusting the nozzle output range and distance according to actual use needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable high-pressure water mist fire extinguisher, comprising a fire extinguisher body, a first threaded connector on one side of the top of the fire extinguisher body, an output tube sleeved on one end of the first threaded connector, a first threaded connector seat on one end of the output tube, a second threaded connector seat on the other end of the output tube, a nozzle connected to the other side of the second threaded connector seat, a first output hole on one end surface of the nozzle, a second output hole on the periphery of one end of the nozzle, an inner tube inside the nozzle, a conical stop on one end of the nozzle, a linkage rod fixed at the center of one end of the conical stop, a push seat connected to the other end of the linkage rod, and a sealing seat on one end of the inner tube.

[0007] By adopting the above technical solution, the structure of the conical baffle, the first output hole, the sealing seat and the second output hole can be easily rotated according to the actual fire situation during subsequent use, so that the high-pressure water mist sprayed out is in a straight line or fan shape, thereby better extinguishing the fire. The whole has higher flexibility and practicality, is adaptable to spraying in all scenarios, and can accurately extinguish fires.

[0008] Preferably, a pressing rod passes through the inner side of the push base, a protrusion is fixed on the outer ring surface of one end of the push base, an arc-shaped groove is opened on the inner wall of the inner tube, and positioning holes are distributed on one side of the arc-shaped groove.

[0009] Preferably, a push rod is fixedly provided on one end surface of the sealing seat, a sealing ring is sleeved on the outer ring surface of the sealing seat, an auxiliary slider is sleeved on the outer ring surface of one end of the push rod, and a first spring is fixedly connected to one end surface of the auxiliary slider.

[0010] Preferably, a first auxiliary slide plate is fitted onto the outer ring surface of one end of the extrusion rod, and a second spring is fixedly connected to one end surface of the first auxiliary slide plate.

[0011] Preferably, a flow divider is provided in the inner cavity of one end of the nozzle, a metal filter frame is connected to one end of the flow divider, and a second threaded connector is fixed to the end of the nozzle near the second threaded connector.

[0012] Preferably, a protrusion is fixed on the outer ring surface of one end of the nozzle, a magnetic sleeve is sleeved on the outer side of one end of the nozzle, a guide groove is formed on the inner wall of the magnetic sleeve, and a locking hole is formed on the surface of the magnetic sleeve.

[0013] Preferably, a locking rod is provided on the inner side of the protrusion, and a second auxiliary sliding plate is sleeved on the outer ring surface of one end of the locking rod, and a third spring is fixedly connected to one end surface of the second auxiliary sliding plate.

[0014] Preferably, the second output holes are arranged in a circular array along the center point of one end surface of the nozzle, and the second output holes and the nozzle form an integrated structure.

[0015] Preferably, the sealing seat is slidably connected to the inner tube via a push rod, and the push rod is distributed in a circular array along the center point of the sealing seat.

[0016] Preferably, the inner diameter of the guide groove is adapted to the outer diameter of the convex strip, and the magnetic sleeve is slidably connected to the convex strip through the guide groove.

[0017] This invention provides a portable high-pressure water mist fire extinguisher. It has the following beneficial effects:

[0018] 1. The present invention, through the design of a conical baffle, a first output hole, a sealing seat, and a second output hole, allows for easy rotation of different output holes according to the actual fire situation during subsequent use, thereby making the sprayed high-pressure water mist appear in a direct current or fan shape, thus better extinguishing the fire.

[0019] 2. The present invention, through the structure of the extrusion rod, push rod, auxiliary slider and first spring, can facilitate the subsequent push rod to be pushed when the extrusion rod is input into the inner side of the positioning hole, thereby pushing the sealing seat to realize the position adjustment of the sealing seat. As the position of the sealing seat is adjusted, the shape of the water mist output of the nozzle can be adjusted, so as to adjust according to the actual fire extinguishing needs.

[0020] 3. The present invention uses an extrusion rod with an embedded magnetic block in conjunction with a magnetic sleeve, which allows the extrusion rod to slide with the movement of the magnetic sleeve. In subsequent adjustments, the extrusion rod is pushed by the sliding of the magnetic sleeve along the nozzle surface, which facilitates the extrusion rod to disengage from the inner side of the positioning hole and realize the passage of the second output hole. At the same time, the sealing seat is reset to realize the resealing of the outer space of the inner tube, so that the two output holes can work independently and without affecting each other.

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 - Appendix Figure 11 This invention provides a portable high-pressure water mist fire extinguisher, comprising a fire extinguisher body 1, a first threaded connector 2 on one side of the top of the fire extinguisher body 1, an output tube 3 sleeved on one end of the first threaded connector 2, a first threaded connector seat 4 on one end of the output tube 3, a second threaded connector seat 5 on the other end of the output tube 3, a nozzle 6 connected to the other side of the second threaded connector seat 5, a first output hole 7 opened on one end surface of the nozzle 6, a second output hole 8 opened on the periphery of one end of the nozzle 6, an inner tube 9 provided in the inner cavity of the nozzle 6, a conical stop 10 distributed on one end of the nozzle 6, a linkage rod 11 fixed at the center of one end of the conical stop 10, a push seat 12 connected to the other end of the linkage rod 11, and a sealing seat 18 provided at one end of the inner tube 9.

[0035] Specifically, during use, one end of the output pipe 3 is pre-connected to the first threaded connector 2 via the first threaded connector 4. Then, the nozzle 6 is connected to the second threaded connector 5, achieving a quick connection between the output pipe 3 and the fire extinguisher body 1, and between the nozzle 6 and the output pipe 3. Subsequently, in the initial state during use, the sealing seat 18 tightly adheres to one end surface of the inner pipe 9. The sealing seat 18 seals the gap between the inner pipe 9 and the inner wall of the nozzle 6. A through hole is located at the center of the sealing seat 18, allowing water to enter the inner side of the inner pipe 9 during subsequent water flow. The water entering the inner pipe 9 is then output through the first output hole 7. Since the first output hole 7 is conical in shape, and a conical baffle 10 is distributed on one side of the first output hole 7, this design facilitates the subsequent water output process. By combining the conical baffle 10, the water flow can be output in a conical shape, thereby increasing the coverage area of ​​the fire extinguisher and improving the extinguishing effect, making it more practical. When it is necessary to increase the spray distance of the fire extinguisher, push the conical baffle 10. At this time, the movement of the conical baffle 10 will cause the linkage rod 11 to push the push seat 12. As the push seat 12 moves inside the inner tube 9, when the push seat 12 moves to the appropriate position, the sealing seat 18 will disengage from one end surface of the inner tube 9. At this time, the conical baffle 10 will seal the first output hole 7. Then, when the water flows into the inside of the nozzle 6, it will flow into the gap between the inner tube 9 and the nozzle 6, which will facilitate the subsequent output through the second output hole 8. Since the second output hole 8 is circular, the water flow can be concentrated and output, thereby increasing the spray distance and enabling the entire device to cover a greater distance when in use.

[0036] Please see the appendix Figure 6 and attached Figure 9 A pressing rod 13 passes through the inner side of the push seat 12. A protrusion 14 is fixed on the outer ring surface of one end of the push seat 12. An arc groove 15 is opened on the inner wall of the inner tube 9. A positioning hole 16 is distributed on one side of the arc groove 15.

[0037] Specifically, when the conical stop 10 is pushed, it will push the linkage rod 11. At this time, the linkage rod 11 will push the push seat 12, which will cause the push seat 12 to slide along the arc groove 15 opened on the inner wall of the inner tube 9 with the protrusion 14 fixed on the outer ring surface of one end. Since the arc groove 15 is spirally opened, when the protrusion 14 slides along the arc groove 15, it will cause the push seat 12 to make a circular motion, which makes it convenient to use the movement of the push seat 12 to drive the extrusion rod 13 to move to one side of the positioning hole 16. When the center lines of the two are on the same center line, one end of the extrusion rod 13 will be input into the inner side of the positioning hole 16, thereby realizing the limiting treatment of the push seat 12.

[0038] Please see the appendix Figure 5 and attached Figure 8 A push rod 17 is fixedly provided on one end surface of the sealing seat 18, a sealing ring 19 is sleeved on the outer ring surface of the sealing seat 18, an auxiliary slider 20 is sleeved on the outer ring surface of one end of the push rod 17, and a first spring 21 is fixedly connected to one end surface of the auxiliary slider 20.

[0039] Specifically, when the push rod 17 is subjected to a pushing force, it will slide within the inner cavity of the inner tube 9. As the push rod 17 moves, it will push the auxiliary slider 20. The movement of the auxiliary slider 20 will then cause the first spring 21 to deform and generate a reverse force. This reverse force will facilitate the subsequent reset of the auxiliary sealing seat 18, allowing the sealing seat 18 to be used to seal the gap between the inner tube 9 and the inner wall of the nozzle 6.

[0040] Please see the appendix Figure 9 The outer ring surface of one end of the compression rod 13 is fitted with a first auxiliary slide plate 22, and a second spring 23 is fixedly connected to one end of the surface of the first auxiliary slide plate 22.

[0041] Specifically, when the subsequent pressing rod 13 is driven to one side of the positioning hole 16 along with the movement of the pusher 12, the center line of the pressing rod 13 and the center line of the positioning hole 16 are on the same center line. At this time, the pressure applied to the pressing rod 13 disappears. Since the pressing rod 13 will cause the first auxiliary slide plate 22 to deform and generate a reverse force when it is pressed, when the pressure applied to the pressing rod 13 disappears, the reverse force generated by the deformation of the second spring 23 will push the first auxiliary slide plate 22 in the opposite direction. Then, the movement of the first auxiliary slide plate 22 will drive the pressing rod 13 to reset, thereby inputting one end of the pressing rod 13 into the positioning hole 16 to achieve the limiting treatment of the pusher 12.

[0042] Please see the appendix Figure 5 A flow divider 24 is provided in the inner cavity of one end of the nozzle 6. A metal filter frame 25 is connected to one end of the flow divider 24. A second threaded connector 26 is fixed to one end of the nozzle 6 near the second threaded connector 5.

[0043] Specifically, when installing the nozzle 6, the second threaded connector 26 fixed at one end of the nozzle 6 is pre-installed into the inner side of the second threaded connector 5. Then, the nozzle 6 is turned to quickly connect the second threaded connector 26 with the second threaded connector 5, thus achieving a quick connection between the nozzle 6 and the output pipe 3. During subsequent liquid flow, as the liquid is introduced into the inner side of the nozzle 6, the conical diverter 24 can perform simple diversion of the water flow. The diverted water flow then passes through the metal filter frame 25, which can then perform simple filtration and impurity removal of the water flow, preventing excessive impurities from clogging the nozzle 6.

[0044] Please see the appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 and attached Figure 10 A protrusion 27 is fixed on the outer ring surface of one end of the nozzle 6, and a magnetic sleeve 28 is sleeved on the outer side of one end of the nozzle 6. A guide groove 29 is opened on the inner wall of the magnetic sleeve 28, and a locking hole 30 is opened on the surface of the magnetic sleeve 28.

[0045] Specifically, when the magnetic sleeve 28 needs to be moved later, the magnetic sleeve 28 will move along the protrusion 27 fixed on the outer ring surface of one end of the nozzle 6 through the guide groove 29 opened in its inner wall, thereby improving the stability of the magnetic sleeve 28 during the movement process.

[0046] Since the magnetic sleeve 28 is made of a magnetic material, when the magnetic sleeve 28 moves to a suitable position along the outer ring surface of one end of the nozzle 6, the magnetic pole of the magnetic sleeve 28 near the nozzle 6 is aligned with the magnetic pole of the extrusion rod 13 facing the inner wall of the nozzle 6. As a result, the extrusion rod 13 will be pushed under the action of like poles repulsion, which will facilitate the subsequent disengagement of the extrusion rod 13 from the positioning hole 16.

[0047] Please see the appendix Figure 11 A locking rod 31 is provided on the inner side of the protrusion 27. A second auxiliary slide plate 32 is sleeved on the outer ring surface of one end of the locking rod 31. A third spring 33 is fixedly connected to one end surface of the second auxiliary slide plate 32.

[0048] Specifically, when the magnetic sleeve 28 slides along the surface of the protrusion 27 to the appropriate position, the locking hole 30 on the surface of the magnetic sleeve 28 and the center line of the locking rod 31 are on the same center line. Then, the pressure applied to the locking rod 31 disappears. Since the second auxiliary slide plate 32 will cause the third spring 33 to deform and generate a reverse force when the locking rod 31 is pressed down, when the pressure applied to the locking rod 31 disappears, the reverse force generated by the deformation of the third spring 33 will push the second auxiliary slide plate 32 in the opposite direction. Then, the second auxiliary slide plate 32 will be used to drive the locking rod 31 to reset, and one end of the locking rod 31 will be input into the inside of the locking hole 30 to achieve the limiting treatment of the magnetic sleeve 28.

[0049] The two ends of the third spring 33 are fixedly connected to one end surface of the second auxiliary slide plate 32 and the inner wall of the protrusion 27, respectively.

[0050] Please see the appendix Figure 4 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 The second output hole 8 is arranged in a circular array along the center point of one end surface of the nozzle 6, and the second output hole 8 and the nozzle 6 form an integrated structure.

[0051] Specifically, by combining multiple second output holes 8 arranged in a ring array, it is possible to make the high-pressure water mist output in a DC state, which makes it easier for the high-pressure water mist to be sprayed further.

[0052] Please see the appendix Figure 5 and attached Figure 8 The sealing seat 18 is slidably connected to the inner tube 9 via the push rod 17, and the push rod 17 is distributed in a ring array along the center point of the sealing seat 18.

[0053] Specifically, when the push rod 17 is pushed by force during use, the movement of the push rod 17 will push the sealing seat 18, which will facilitate the subsequent sliding of the sealing seat 18 along the inner side of the nozzle 6. The combination of the push rod 17 can improve the stability of the sealing seat 18 during movement.

[0054] Please see the appendix Figure 4 Appendix Figure 10 and attached Figure 11 The inner diameter of the guide groove 29 is matched with the outer diameter of the protrusion 27, and the magnetic sleeve 28 is slidably connected to the protrusion 27 through the guide groove 29.

[0055] Specifically, when the magnetic sleeve 28 is subjected to force and moves, it will slide along the protrusion 27 through the guide groove 29. The engagement between the protrusion 27 and the guide groove 29 can improve the stability of the magnetic sleeve 28 during movement.

[0056] Workflow: During use, one end of the output pipe 3 is pre-connected to the first threaded connector 2 via the first threaded connector 4. Then, the nozzle 6 is connected to the second threaded connector 5 via the second threaded connector 26, achieving quick connection between the output pipe 3 and the fire extinguisher body 1, and between the nozzle 6 and the output pipe 3. Subsequently, during use, in the initial state, the sealing seat 18 tightly fits against one end surface of the inner pipe 9. The sealing seat 18 seals the gap between the inner pipe 9 and the inner wall of the nozzle 6. A through hole is located at the center of the sealing seat 18, allowing water to enter the inner pipe 9 through this through hole during subsequent water flow. The water flowing into the inner tube 9 is then output through the first output hole 7. Since the first output hole 7 is conical in shape and has a conical baffle 10 on one side, the water flow is output in a conical manner, increasing the coverage area and extinguishing effect of the fire extinguisher. This improves its overall practicality. When the spray distance needs to be increased, the conical baffle 10 is pushed. The movement of the conical baffle 10 causes the linkage rod 11 to push the push seat 12, which in turn drives the protrusion fixed to one end of its outer ring surface. 14 slides along the arc-shaped groove 15 opened on the inner wall of the inner tube 9. Since the arc-shaped groove 15 is spirally opened, when the protrusion 14 slides along the arc-shaped groove 15, it will cause the pusher 12 to make a circular motion. This facilitates the subsequent movement of the pusher 12 to drive the extrusion rod 13 to one side of the positioning hole 16. At this time, the center line of the extrusion rod 13 and the center line of the positioning hole 16 are on the same center line. At this time, the pressure applied to the extrusion rod 13 disappears. Since the extrusion rod 13 is extruded, the first auxiliary slide plate 22 will cause the second spring 23 to deform and generate a reverse force. Therefore, when the pressure applied to the extrusion rod 13 disappears, the reverse force generated by the deformation of the second spring 23 will push in the opposite direction. The first auxiliary slide plate 22 is moved, and the movement of the first auxiliary slide plate 22 drives the extrusion rod 13 to reset, thereby inputting one end of the extrusion rod 13 into the positioning hole 16 to limit the push seat 12. The sealing seat 18 will disengage from one end surface of the inner tube 9, and at this time the conical stop 10 will seal the first output hole 7. Then, when the water flows into the inside of the nozzle 6, it will flow into the gap between the inner tube 9 and the nozzle 6, so that it can be output through the second output hole 8. Since the second output hole 8 is circular, the water flow can be concentrated and output, thereby increasing the distance of the water jet and enabling the entire device to cover a greater distance when in use.

[0057] In the subsequent liquid flow, as the liquid is input into the inner side of the nozzle 6, the water flow can be simply diverted by the provided conical diverter seat 24. The diverted water flow will then pass through the provided metal filter frame 25, and the metal filter frame 25 can be used to achieve simple filtration and impurity removal of the water flow, preventing the nozzle 6 from being blocked by too many impurities.

[0058] When the magnetic sleeve 28 needs to be moved later, the magnetic sleeve 28 will move along the protrusion 27 fixed on the outer ring surface of one end of the nozzle 6 through the guide groove 29 opened in its inner wall, thereby improving the stability of the magnetic sleeve 28 during the movement. Since the magnetic sleeve 28 is made of magnetic material, when the magnetic sleeve 28 moves to the appropriate position along the outer ring surface of one end of the nozzle 6, the magnetic pole of the magnetic sleeve 28 near the nozzle 6 is aligned with the magnetic pole of the extrusion rod 13 facing the inner wall of the nozzle 6. Therefore, under the action of like poles repulsion, it will push the extrusion rod 13, which will facilitate the subsequent disengagement of the extrusion rod 13 from the positioning hole 16. When the magnetic sleeve 28 moves along the protrusion 27, When the surface slides to the appropriate position, the center line of the locking hole 30 on the surface of the magnetic sleeve 28 and the center line of the locking rod 31 are on the same center line. Then, the pressure applied to the locking rod 31 disappears. Since the second auxiliary slide plate 32 will cause the third spring 33 to deform and generate a reverse force when the pressure applied to the locking rod 31 disappears, the reverse force generated by the deformation of the third spring 33 will push the second auxiliary slide plate 32 in the opposite direction. Then, the second auxiliary slide plate 32 will be used to drive the locking rod 31 to reset, and one end of the locking rod 31 will be inserted into the inside of the locking hole 30 to achieve the limiting treatment of the magnetic sleeve 28.
