Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, specifically a portable clean gas fire extinguishing device. Background Technology

[0002] Clean gas fire extinguishing systems are suitable for applications involving electrical equipment, precision instruments, and archives where water-based or powder extinguishing agents are not appropriate. These systems need to be quickly deployed and aimed at the fire source in the early stages of a fire; therefore, portability, operational continuity, and gas release stability directly affect their effectiveness.

[0003] Existing portable clean gas fire extinguishing devices mostly rely on a single gas storage container to provide the extinguishing medium. If the gas storage container has a large volume, the overall size and weight of the device will increase accordingly, which is not conducive to quick carrying and one-handed operation; if a small gas cylinder is used to reduce the size of the device, the gas storage capacity of a single gas cylinder is limited, which is difficult to meet the needs of continuous discharge.

[0004] Even when multiple small gas cylinders are used in the same device, the centralized assembly and continuous release of these cylinders within a portable structure still needs to be addressed. Relying on manual triggering of each cylinder individually increases the operational burden in emergencies; if a continuous gas supply cannot be established according to the usage process, it is difficult to balance the requirements of miniaturized assembly and continuous discharge. Therefore, there is an urgent need for a clean gas fire extinguishing device that can accommodate multiple small gas cylinders in a portable structure and achieve continuous gas release during a single operation. Summary of the Invention

[0005] This application provides a portable clean gas fire extinguishing device, the main purpose of which is to accommodate multiple small gas cylinders in a portable structure and to allow the gas to be released continuously during a single operation.

[0006] To achieve the above objectives, this application provides a portable clean gas fire extinguishing device, including a main body, a nozzle disposed at the front end of the main body, a handheld part disposed on the lower side of the main body, and a control component disposed at the handheld part, and further including: The carrier is detachably assembled in the inner cavity of the main body, and the carrier has multiple mounting positions for placing replacement gas cylinders, and the multiple mounting positions are in communication with the inner cavity of the main body; A sealing and locking component is disposed on the main body for locking the carrier in the inner cavity of the main body and keeping the inner cavity of the main body sealed; An active puncture device is installed at the position corresponding to the first replacement gas cylinder. The active puncture device is driven to cooperate with the control component to puncture the first replacement gas cylinder when the control component is triggered. A valve assembly is connected between the inner cavity of the main body and the nozzle. The valve assembly is driven to cooperate with the control component to open when the control component is triggered and close when the control component is reset. Multiple passive puncture devices are respectively installed at the corresponding positions of the remaining replacement gas cylinders, except for the first replacement gas cylinder; The nozzle transmission mechanism is disposed inside the nozzle and includes a driven fan blade, a torque transmission box, a transmission assembly, and a screw. The driven fan blade is located on the airflow path of the nozzle. The driven fan blade is connected to the power input end of the torque transmission box through the transmission assembly, and the screw is connected to the power output end of the torque transmission box. A movable triggering component is disposed on the main body and cooperates with the screw drive. The movable triggering component can move along the arrangement direction of multiple replacement gas cylinders when the screw rotates, and sequentially squeeze the corresponding passive puncture member during the movement, so that the corresponding passive puncture member moves toward the corresponding replacement gas cylinder and punctures the corresponding replacement gas cylinder. The top center of the main body is provided with a straight protrusion extending along the length direction of the main body. The moving trigger component is linearly movable in the inner cavity of the straight protrusion. A plurality of the passive puncture components are arranged at intervals below the moving trigger component along the extension direction of the straight protrusion. The moving trigger assembly includes a moving seat, a moving plate, an engaging post, and a puncture squeeze roller. The moving seat is linearly movable and engaged in the inner cavity of the linear protrusion. The moving plate is vertically and vertically mounted on the moving seat. The engaging post is located at the bottom end of the moving plate and can engage in the threaded groove of the screw. The puncture squeeze roller is located below the moving seat and is used to squeeze the passive puncture member when passing through it.

[0007] In one feasible embodiment, the portable clean gas fire extinguishing device further includes a reset member capable of lifting the movable piece to disengage the engagement post from the threaded groove of the screw, and capable of moving the movable seat along the straight protrusion to the initial position.

[0008] In one feasible implementation, the nozzle is provided with an outer grid and an inner grid located inside the outer grid, the driven fan blade is rotatably disposed between the outer grid and the inner grid, and the fan blade shaft of the driven fan blade is connected to the power input end of the torque transmission box through the transmission assembly.

[0009] In one feasible implementation, the active puncture component includes a gear, an eccentric cam, and a puncture knife. The control component is provided with a rack that meshes with the gear. The gear and the eccentric cam are synchronously connected and rotate. The puncture knife is positioned above the eccentric cam and corresponds to the first replacement gas cylinder. When the control component moves, the rack drives the gear and the eccentric cam to rotate, and the eccentric cam squeezes the puncture knife to puncture the first replacement gas cylinder.

[0010] In one feasible implementation, the valve assembly includes a valve body connected between the nozzle and the inner cavity of the main body, and a valve trigger plate disposed on the valve body. The control component is provided with a drive column, which can press the valve trigger plate when the control component moves, so as to open the valve body.

[0011] In one feasible embodiment, the portable clean gas fire extinguishing device further includes: an elastic limiting component and a safety pin component. The elastic limiting component includes a fixed base, an end, a spring, and a slot. The fixed base is disposed inside the main body. The end is connected to the front end of the control component and is movably disposed within the fixed base. The spring is sleeved on or abuts against the outside of the end to reset the control component. The slot is disposed on the end, and the safety pin component can be inserted into the slot to restrict the movement of the control component.

[0012] In one feasible embodiment, the carrier is provided with a placement groove and a plurality of partitions, the plurality of partitions being spaced apart in the placement groove to form a plurality of installation positions for placing replacement gas cylinders, the upper half of the partitions being provided with concave arc-shaped edges to allow the plurality of installation positions to communicate with each other in the inner cavity of the main body, and the outer end of the carrier being provided with a sealing tail piece, the sealing tail piece being used to seal and cooperate with the tail end of the main body.

[0013] In one feasible embodiment, the sealing and locking component includes a lever, a threaded post, a linear lifting block, pressing teeth, and pressure teeth. The lever is rotatably disposed on the rear side of the handle or below the main body. The threaded post is connected to the lever and located inside the main body. The linear lifting block is threadedly engaged with the threaded post. A plurality of pressing teeth are disposed at the top of the linear lifting block, and a plurality of pressure teeth are disposed on the lower end face of the carrier. Both the pressing teeth and the pressure teeth have inclined surfaces so that when the linear lifting block moves upward, the contact between the pressing teeth and the pressure teeth restricts the carrier and pushes the carrier toward the interior of the main body.

[0014] This application provides a portable clean gas fire extinguishing device that centrally houses multiple replacement gas cylinders via a detachable carrier. This allows the device to maintain its portable form while providing a multi-cylinder gas supply, accommodating both miniaturized assembly and continuous discharge requirements. A continuous action chain is formed through control components, an active puncture structure, an airflow-driven structure, and a moving trigger structure. This ensures that the gas flow released from the first cylinder triggers subsequent cylinders sequentially, reducing the need for manual cylinder opening and improving the continuity of extinguishing medium release and the maintenance of consistent discharge pressure. By integrating cylinder assembly, puncture triggering, and gas output into a single unit, multiple small cylinders can release gas along a predetermined path. The device has a compact structure and clear operating logic, making it suitable for rapid retrieval and continuous discharge in emergency situations. Locking, sealing, resetting, and limiting mechanisms further enhance the stability of the assembled cylinders, facilitating post-use maintenance and reducing the possibility of unused cylinders being triggered randomly.

[0026] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. It should be understood that the described embodiments are only used to illustrate the technical solution and not to limit the scope of protection; in the absence of conflict, the technical features in this embodiment can be combined with each other, and equivalent substitutions, conventional modifications or adaptive adjustments to the position of components made based on this technical solution should all fall within the protection scope of this technical solution.

[0027] In the description of this embodiment, it should be understood that the term "front end" refers to the end in which the extinguishing gas is ejected, and the term "rear end" refers to the end opposite to the front end and which is convenient for loading or unloading the carrier 40. The terms "above," "below," "inner side," "outer side," etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing this technical solution and simplifying the description. They do not mean that the device or component referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation on this technical solution.

[0028] Please see Figures 1 to 10This embodiment provides a portable clean gas fire extinguishing device for spraying clean fire extinguishing gas into electrical cabinets, archives, precision equipment, or other scenarios where water-based fire extinguishing media are unsuitable. The device includes a main body 10, a nozzle 20, a handheld part 30, a carrier 40, a control component 50, a safety pin component 60, a sealing and locking component 70, a replacement gas cylinder 80, and a reset component 90. The main body 10 constitutes the main supporting housing of the device. The nozzle 20 is located at the front end of the main body 10, the handheld part 30 is located at the lower rear of the main body 10, and the control component 50 is located near the main body 10. When the operator holds the handheld part 30, they can trigger the control component 50 with their fingers, causing the replacement gas cylinder 80 to release clean fire extinguishing gas, which is then sprayed outwards through the nozzle 20.

[0029] Please see Figure 1 and Figure 2 The main body 10 has an overall elongated structure for easy handheld use. The handle 30 is tilted downwards and backwards relative to the main body 10, giving the device a pistol-like grip. The nozzle 20 is installed at the front end of the main body 10. The interior of the main body 10 forms an inner cavity for accommodating the carrier 40, the replacement gas cylinder 80, and facilitating gas flow. The carrier 40 can be inserted into the inner cavity of the main body 10 in a straight line along its length from the rear end, and can also be removed from the main body 10 after the sealing locking component 70 is released, so as to replenish or replace the replacement gas cylinder 80 in the carrier 40. By centrally installing multiple small-volume replacement gas cylinders 80 in the detachable carrier 40, this device can form a multi-cylinder continuous gas supply structure while maintaining portability, avoiding the problems of bulkiness, inconvenience, and difficulty in replacement associated with traditional large-volume metal pressure cylinders.

[0030] Please see Figure 2 , Figure 4 and Figure 6 The carrier 40 includes a placement groove 41, multiple partitions 42, and a sealing tail piece 43. The placement groove 41 is arranged along the length of the carrier 40, and the multiple partitions 42 are spaced apart within the placement groove 41 to divide it into multiple installation positions for placing replacement gas cylinders 80. The multiple replacement gas cylinders 80 can be arranged sequentially along the length of the main body 10, with each replacement gas cylinder 80 corresponding to a specific puncture position, facilitating subsequent puncture and gas release. The upper half of the partition 42 has a concave arc-shaped edge, which maintains communication between adjacent installation positions, allowing the gas released from the punctured replacement gas cylinder 80 to enter the inner cavity of the main body 10 and collectively form a common pressure environment. The sealing tail piece 43 is located at the outer end of the carrier 40. When the carrier 40 is installed into the main body 10, the sealing tail piece 43 engages with the tail end of the main body 10, thereby improving the sealing of the inner cavity of the main body 10 and reducing the possibility of high-pressure clean gas leakage from the tail end of the main body 10.

[0031] Please see Figure 2 , Figure 4 and Figure 10 As shown, a sealing and locking component 70 is provided on the main body 10. The sealing and locking component 70 is used to lock the carrier 40 after it is installed in the main body 10, and to form a reliable seal between the sealing tail piece 43 of the carrier 40 and the tail end of the main body 10. The sealing and locking component 70 includes a lever 71, a threaded post 72, a linear lifting block 73, pressing teeth 74, and pressure teeth 75. The lever 71 is rotatably disposed on the rear side of the handheld part 30 or below the main body 10. The threaded post 72 is connected to the lever 71 and located inside the main body 10. The linear lifting block 73 is threadedly engaged with the threaded post 72. Multiple pressing teeth 74 are disposed on the top of the linear lifting block 73, and multiple pressure teeth 75 are disposed on the lower end face of the carrier 40. When the operator rotates the lever 71, the lever 71 drives the threaded post 72 to rotate, and the threaded post 72 drives the linear lifting block 73 to move in the vertical direction. When the linear lifting block 73 moves upward, the pressing tooth 74 extends into the corresponding position on the lower end face of the carrier 40 and contacts the pressure tooth 75. The inclined surfaces of the pressing tooth 74 and the pressure tooth 75 cooperate with each other, which on the one hand restricts the movement of the carrier 40 relative to the main body 10, and on the other hand forces the carrier 40 to make a small displacement towards the inside of the main body 10 as the linear lifting block 73 continues to move upward, so that the sealing tail piece 43 is further pressed against the tail end of the main body 10, thereby improving the locking stability and sealing reliability. When it is necessary to remove the carrier 40, the lever 71 is rotated in the opposite direction to make the linear lifting block 73 descend, the pressing tooth 74 retracts from the position of the pressure tooth 75, and the carrier 40 can be pulled out along the rear end of the main body 10.

[0032] Please see Figure 2 and Figure 9 A straight protrusion 11 is provided at the center of the top of the main body 10, extending along the length of the main body 10. A movable trigger assembly 12 is provided in the inner cavity of the straight protrusion 11, and the movable trigger assembly 12 can move linearly along the extension direction of the straight protrusion 11. Below the movable trigger assembly 12, a plurality of passive puncture members 14 are provided, which are spaced apart along the length of the main body 10 and correspond to the remaining replacement gas cylinders 80 except for the first replacement gas cylinder 80. The passive puncture members 14 are vertically and vertically disposed in the upper part of the inner cavity of the main body 10. When the passive puncture member 14 is pressed downward by the movable trigger assembly 12, the passive puncture member 14 moves toward the corresponding replacement gas cylinder 80 and punctures the replacement gas cylinder 80, causing the replacement gas cylinder 80 to release clean fire extinguishing gas. By setting multiple passive puncture components 14 to correspond one-to-one with multiple replacement gas cylinders 80, the replacement gas cylinders 80 can be punctured sequentially according to the moving order of the moving trigger component 12, forming a continuous gas supply process. The passive puncture components 14 are in a high position by default, which can be achieved by assembling a spring.

[0033] Please see Figure 2 , Figure 3 and Figure 4 The nozzle transmission mechanism is located inside the nozzle 20 and includes a driven fan blade 23, a torque transmission box 24, a transmission assembly 25, and a screw 26. The driven fan blade 23 is located on the airflow path of the nozzle 20. The driven fan blade 23 is connected to the power input end of the torque transmission box 24 through the transmission assembly 25, and the screw 26 is connected to the power output end of the torque transmission box 24.

[0034] Furthermore, the nozzle 20 is equipped with a nozzle 16, an outer grille 21, an inner grille 22, and a driven fan blade 23. The driven fan blade 23 is located between the inner grille 22 and the outer grille 21. The torque transmission box 24 is located above the nozzle 16, the transmission assembly 25 is located inside the outer grille 21, and the screw 26 is located in the upper inner cavity of the main body 10. The nozzle 16 is located inside the nozzle 20 and communicates with the inner cavity of the main body 10 through a valve assembly 17. When the valve assembly 17 is open, the clean extinguishing gas in the inner cavity of the main body 10 can be sprayed outward from the nozzle 20 through the nozzle 16. The outer grille 21 is located in the outer area of ​​the nozzle 20, the inner grille 22 is spaced apart inside the outer grille 21, and the driven fan blade 23 is rotatably arranged between the outer grille 21 and the inner grille 22 and is located in the airflow path of the nozzle 20. When clean extinguishing gas is ejected from nozzle 20, the flowing gas drives the driven blades 23 to rotate. The blade shaft of the driven blades 23 transmits power to the power input end of torque transmission box 24 through transmission assembly 25. Torque transmission box 24 converts speed and torque and drives screw 26 to rotate through its power output end. Screw 26 extends along the length of the main body 10 and is in transmission cooperation with the moving trigger assembly 12. Therefore, when screw 26 rotates, it can drive the moving trigger assembly 12 to move along the arrangement direction of multiple replacement gas cylinders 80. The above structure uses the flow power of the released gas itself to drive the subsequent puncture action, without requiring the operator to control each gas cylinder individually, nor does it require setting up an independent motor or complex control system. The mechanical action chain ensures that multiple replacement gas cylinders 80 can be released sequentially.

[0035] Please see Figure 9The moving trigger assembly 12 includes a moving seat 121, a moving plate 122, an engaging post 123, and a piercing and squeezing roller 124. The moving seat 121 is linearly movable and engaged in the inner cavity of the linear protrusion 11, and is movably sleeved on the outside of the screw 26. The moving plate 122 is vertically and vertically disposed in the upper inner cavity of the moving seat 121, and the engaging post 123 is disposed at the middle of the bottom end of the moving plate 122. The engaging post 123 can enter downward into the threaded groove of the screw 26, thereby forming a disengaged threaded drive engagement between the moving seat 121 and the screw 26. When the screw 26 rotates and the engaging post 123 is located in the threaded groove of the screw 26, the screw 26 drives the moving plate 122 and the moving seat 121 to move along the linear protrusion 11 through the engaging post 123. The puncture squeeze roller 124 is disposed below the movable seat 121 and moves with the movable seat 121. When the puncture squeeze roller 124 passes any passive puncture member 14, the puncture squeeze roller 124 applies a downward squeezing force to the passive puncture member 14, causing the passive puncture member 14 to move toward the corresponding replacement gas cylinder 80 and complete the puncture. When the puncture squeeze roller 124 adopts a rotatable roller structure, it can reduce the frictional resistance when passing through the passive puncture member 14, making the movement of the moving trigger assembly 12 smoother.

[0036] Please see Figure 9 The reset component 90 is used to reset the moving trigger assembly 12 after use interruption, fire suppression, or replacement of the gas cylinder 80. The reset component 90 can be configured to lift the moving piece 122, such as a magnetic reset component or a lifting component that can move the moving piece 122 upwards from the outside of the linear protrusion 11. When the moving trigger assembly 12 needs to be reset, the operator brings the reset component 90 close to the outside of the linear protrusion 11, causing the reset component 90 to lift the moving piece 122. The moving piece 122 then moves the engaging column 123 upwards and disengages from the threaded groove of the screw 26. At this time, the transmission constraint between the moving seat 121 and the screw 26 is released, and the operator can move the reset component 90 along the linear protrusion 11, causing the moving seat 121 to move back to its initial position with the reset component 90. After the movable base 121 returns to its initial position, the reset member 90 is removed, and the movable piece 122 and the engaging post 123 fall back down. The engaging post 123 re-enters the threaded groove of the screw 26, thereby restoring the movable trigger assembly 12 to a state where it can be driven by the screw 26. This reset structure allows the movable trigger assembly 12, which has moved a certain distance, to be reset without disassembling the main body 10, facilitating the reuse of the device.

[0037] Please see Figure 2 and Figure 8The active puncture component 15 is positioned corresponding to the first replacement gas cylinder 80, which is the first replacement gas cylinder 80 to be triggered, located closer to the nozzle 20. The active puncture component 15 includes a gear 151, an eccentric cam 152, and a puncture blade 153. A rack meshing with the gear 151 is mounted on the control component 50. The gear 151 is rotatably mounted in the lower half of the inner cavity of the main body 10. The eccentric cam 152 rotates synchronously with the gear 151. The puncture blade 153 is positioned above the eccentric cam 152 and corresponds to the first replacement gas cylinder 80. When the operator presses the control component 50, the control component 50 moves the rack, which in turn rotates the gear 151, which in turn rotates the eccentric cam 152. During rotation, the eccentric cam 152 presses upward against the lower base of the puncture blade 153, causing the puncture blade 153 to move towards and puncture the first replacement gas cylinder 80. After the first replacement cylinder 80 is punctured, the clean extinguishing gas inside is released into the inner cavity of the main body 10 and enters the nozzle 20 when the valve assembly 17 is opened. Since the active puncture component 15 is directly triggered by the control component 50, the first spray has a clear starting action; subsequent replacement cylinders 80 are punctured in sequence by the moving trigger component 12 and the passive puncture component 14 driven by the airflow at the nozzle 20, thus forming a gas supply mode of first active activation and then airflow continuous triggering.

[0038] Please see Figure 2 and Figure 8 The valve assembly 17 connects the inner cavity of the main body 10 and the nozzle 16, and is used to control whether clean extinguishing gas enters the nozzle 20. The valve assembly 17 includes a valve body and a valve trigger plate 171. The valve body is connected between the nozzle 16 and the inner cavity of the main body 10. The valve trigger plate 171 is mounted on the valve body and can be triggered to open the valve body by pressing. The control component 50 is equipped with a drive column 172, which corresponds to the valve trigger plate 171. When the control component 50 is pressed, the drive column 172 moves with the control component 50 and presses the valve trigger plate 171, causing the valve body to open; when the control component 50 is released and reset, the drive column 172 moves away from the valve trigger plate 171, and the valve body returns to the closed state. Thus, when the active puncture component 15 punctures the first replacement gas cylinder 80, the valve assembly 17 can open simultaneously, allowing the released clean extinguishing gas to be sprayed out through the nozzle 16 in a timely manner; and after the operator releases the control component 50, even if there is still a certain pressure in the inner cavity of the main body 10, the valve assembly 17 can close, reducing unnecessary gas leakage.

[0039] Please see Figure 2 and Figure 7The main body 10 also includes an elastic limiting component 13 and a safety pin component 60. The elastic limiting component 13 includes a fixed base 131, an end head 132, a spring 133, and a slot 134. The fixed base 131 is located inside the main body 10 and below the nozzle 20. The end head 132 is connected to the front end of the control component 50 and can move horizontally within the fixed base 131. The spring 133 is located outside the end head 132 and within the fixed base 131. The spring 133 is used to push the end head 132 and the control component 50 back to their original positions when the control component 50 loses external force. The slot 134 is located at the lower end of the end head 132, and the safety pin component 60 can be inserted into the slot 134. When the safety pin 60 is inserted into the slot 134, the end 132 is restricted from movement, and the control component 50 cannot be effectively triggered, thus preventing accidental activation of the control component 50 during transportation, storage, or replacement of the replacement gas cylinder 80, which could lead to the replacement cylinder 80 being punctured. When fire extinguishing is required, the operator first releases the safety pin 60 to allow the end 132 to move, and then presses the control component 50 to initiate the spray.

[0040] In some examples, a limit button (not shown in the accompanying drawings) can also be provided at the nozzle 20 to prevent the driven fan blade 23 from rotating. This limit button restricts the rotation of the driven fan blade 23 when it is necessary to safely replace the replacement gas cylinder 80 or release residual pressure within the main body 10. Specifically, when high-pressure gas remains inside the main body 10 after use and further puncture of the subsequent replacement gas cylinder 80 is not desired, the operator presses the limit button, preventing the driven fan blade 23 from rotating with the airflow. This prevents the transmission assembly 25, torque transmission box 24, and screw 26 from driving the movement trigger assembly 12. The operator can then press the control component 50 in a safe direction to open the valve assembly 17 and release the residual gas in the main body 10 through the nozzle 20. Because the driven fan blade 23 is restricted, the screw 26 does not rotate, and the movement trigger assembly 12 does not continue forward. Therefore, the unused replacement gas cylinder 80 will not be punctured by the passive puncture component 14, facilitating the removal of the carrier 40 after releasing residual pressure and allowing only the used replacement gas cylinder 80 to be replaced.

[0041] The working process of this embodiment is as follows: In the initial state, the carrier 40 is installed inside the main body 10, and multiple replacement gas cylinders 80 are respectively located in multiple installation positions within the placement groove 41. The sealing locking component 70 is in a locked state, the sealing tail piece 43 presses against the tail end of the main body 10, the safety pin component 60 is inserted into the slot 134, the valve assembly 17 is closed, and the movement trigger component 12 is in the initial position. When needed, the operator pulls out or releases the safety pin component 60 and holds the handheld part 30 to press the control component 50. The control component 50 drives the gear 151 to rotate via a rack and pinion, and the gear 151 drives the eccentric cam 152 to rotate. The eccentric cam 152 squeezes the piercing knife 153, causing the piercing knife 153 to pierce the first replacement gas cylinder 80. On the other hand, the control component 50 drives the drive column 172 to press the valve trigger piece 171, causing the valve assembly 17 to open. The clean extinguishing gas released from the first replacement gas cylinder 80 enters the inner cavity of the main body 10 and is sprayed outward through the valve assembly 17, nozzle 16 and nozzle 20, forming the first extinguishing spray.

[0042] After the initial spray, the gas flows through the nozzle 20 and drives the driven fan blades 23 to rotate. The driven fan blades 23 transmit power to the torque transmission box 24 via the transmission assembly 25, which in turn drives the screw 26 to rotate. The screw 26 drives the moving seat 121 to move gradually along the straight protrusion 11 via the meshing column 123. The piercing and squeezing roller 124 below the moving seat 121 passes sequentially through the passive piercing member 14 corresponding to the second, third, and subsequent replacement gas cylinders 80. Each time the piercing and squeezing roller 124 passes a passive piercing member 14, the passive piercing member 14 is pressed against the corresponding replacement gas cylinder 80 and punctures it, allowing the new replacement gas cylinder 80 to continuously release clean extinguishing gas. Thus, this device can achieve the sequential release of multiple replacement gas cylinders 80 through the airflow-driven mechanical transmission structure while the operator continuously presses the control component 50 and keeps the valve assembly 17 open, thereby extending the spray duration.

[0043] When the fire is extinguished or the operator needs to stop spraying, the operator releases the control component 50. The spring 133 pushes the end 132 and the control component 50 back to their original positions, the drive column 172 moves away from the valve trigger plate 171, the valve assembly 17 closes, and the nozzle 20 stops spraying gas. Since the airflow at the nozzle 20 stops after the valve assembly 17 closes, the driven fan blade 23 stops rotating, and the transmission assembly 25, torque transmission box 24, and screw 26 also stop operating. The moving trigger component 12 remains in its current position. At this time, the unpunctured replacement gas cylinders 80 remain unused. The operator can determine the gas usage based on the position of the moving trigger component 12 or the number of punctured replacement gas cylinders 80 in the carrier 40. During subsequent maintenance, only the used replacement gas cylinders 80 are replaced, thereby reducing gas waste and improving replenishment efficiency.

[0044] When maintenance or replenishment of gas cylinders is required, the operator first confirms that valve assembly 17 is closed and can limit the rotation of driven fan blade 23 via limit button before releasing residual pressure in the inner cavity of main body 10 in a safe direction. After the residual pressure is released, the operator reverses the operation of sealing locking component 70, causing linear lifting block 73 to descend, squeezing teeth 74 to retract from the position of pressure teeth 75, and releasing the locking and compression of carrier 40. Then, carrier 40 is pulled out from the rear end of main body 10, the punctured replacement gas cylinder 80 is removed and replaced with a new replacement gas cylinder 80, and the unpunctured replacement gas cylinder 80 can continue to be used. After replacement, carrier 40 is pushed back into main body 10 along the rear end, so that each replacement gas cylinder 80 corresponds to the puncture position of active puncture component 15 and passive puncture component 14, and then the lever 71 is rotated to relock carrier 40 with sealing locking component 70. If the moving trigger component 12 has deviated from its initial position, the resetting component 90 pulls the moving piece 122 to disengage the engaging column 123 from the threaded groove of the screw 26, and brings the moving seat 121 back to its initial position, thus completing the device reset.

[0045] Through the above structure, this embodiment has at least the following deterministic technical effects: First, multiple replacement gas cylinders 80 are centrally installed in the detachable carrier 40, which can be inserted into or removed from the main body 10 as a whole, facilitating cylinder replenishment, replacement, and positioning; Second, the sealing and locking component 70, through the engagement of the inclined surfaces of the compression teeth 74 and the pressure-bearing teeth 75, locks the carrier 40 while pushing the carrier 40 to press against the tail end of the main body 10, improving the sealing performance of the inner cavity of the main body 10; Third, the first replacement gas cylinder 80 is directly driven by the control component 50 to puncture the active puncture component 15, reliably forming the initial airflow; Fourth... The initial airflow drives the driven fan blade 23 to rotate, and through the transmission assembly 25, torque transmission box 24 and screw 26, it drives the moving trigger assembly 12 forward, so that multiple passive piercing parts 14 pierce the subsequent replacement gas cylinders 80 in sequence, thereby realizing the continuous gas supply of cylinder by cylinder in terms of mechanical structure; fifth, the valve assembly 17 is linked with the control component 50. After the control component 50 is released, the valve assembly 17 closes, which can stop the injection and reduce the continued leakage of residual gas; sixth, the reset component 90 can disengage the engagement column 123 and the screw 26 and drive the moving trigger assembly 12 back to the initial position, so that the device can be reused.

[0046] In some examples, the airflow-driven components within the nozzle 20 are not limited to the driven fan blade 23, but can also be turbines, oscillating baffles, impellers, or pneumatic sliders positioned along the airflow path of the nozzle 20. When clean gas passes through the nozzle 20, the airflow-driven unit can rotate, oscillate, or move linearly under the impact of the airflow, and transmit this action to the subsequent transmission structure, thereby providing driving force for the triggering actuator.

[0047] In some examples, the transmission assembly 25 may include one or more of the following: a gear set, a timing pulley set, a sprocket set, a cam drive set, a ratchet and pawl drive set, or a linkage drive set. The transmission assembly 25 is used to convert the rotation, oscillation, or linear movement generated by the airflow drive unit into a propulsive action of the moving trigger assembly 12 in a predetermined direction, so that the moving trigger assembly 12 can sequentially approach a plurality of passive puncture elements 14.

[0048] In some examples, the torque transmission box 24 can be a gear reducer, a worm gear mechanism, or a planetary gear mechanism. The input end of the torque transmission box 24 is connected to the driven fan blade 23 or other airflow drive unit, and the output end is connected to the screw 26 or other transmission output component; the torque transmission box 24 is used to reduce the output speed and increase the output torque, so that the output end can overcome the resistance generated when the replacement gas cylinder 80 is punctured, and stably drive the moving trigger component 12 to complete the propulsion action.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
