Description

Technical Field

[0001] This invention relates to the technical field of fire extinguishers, and in particular to a portable lithium-ion fire extinguishing device with automatic mixing capability. Background Technology

[0002] Lithium batteries are primary batteries that use lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. They are different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. However, if a lithium battery catches fire, it cannot be extinguished with a dry powder fire extinguisher; only a water-based fire extinguisher can be used. To improve extinguishing efficiency, existing water-based fire extinguishers typically contain various additives. These additives are prone to slight stratification after prolonged storage, which can affect the extinguishing effect. However, people often forget to shake the extinguisher before use.

[0003] Chinese Patent Publication No. CN218685827U, published on March 24, 2023, discloses a novel lithium battery fire extinguisher, comprising a cylinder, base, nozzle, hose, valve, and wall mount. The extinguisher is characterized by a lower end cap fixedly installed at the bottom of the cylinder, a base inserted into the outer side of the lower end cap, a snap-fit ​​bracket fixedly installed on the left side of the base, a pressure gauge fixedly installed through the upper front of the cylinder, a cylinder mouth fixedly installed at the top center of the cylinder, a valve threadedly installed at the center of the cylinder mouth, a sealing ring crimped between the valve and the cylinder mouth, a spring seat mounted at the bottom center of the valve, a suction tube inserted and fixedly installed at the bottom center of the spring seat, and a filter screen fixedly installed at the bottom of the suction tube. A drawback of this invention is that, while the fire extinguisher still requires slight shaking to eliminate stratification during use, it is easy to forget to shake it, affecting the extinguishing effect. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of existing water-based fire extinguishers where multiple additives separate into layers and need to be shaken before use. It provides a portable lithium-ion fire extinguishing device that can automatically mix the extinguishing agents inside the fire extinguisher during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A portable lithium-ion fire extinguishing device with automatic mixing capability, comprising: The bottle body has a press valve installed at its upper end, and the press valve has a control lever inside. A straw, wherein the straw is placed inside the bottle and is connected to the lower end of the press valve; The nozzle is connected to one side of the press valve; A gas storage tank is installed at the upper end of a straw. A gas outlet valve is installed on the gas storage tank. One end of the gas outlet valve is connected to the gas storage tank, and the other end of the gas outlet valve is connected to a gas outlet pipe. The lower end of the gas outlet pipe passes through the straw and is placed inside the bottle.

[0006] The main structure of the fire extinguisher consists of the bottle body, pressing valve, suction tube, and nozzle. The opening and closing of the pressing valve is controlled by raising and lowering a control lever inside the pressing valve. The suction tube draws in the liquid inside the bottle, which then enters the pressing valve and is released through the nozzle. However, a gas tank is installed at the upper end of the suction tube. This gas tank is a press-type gas outlet. When the pressing valve is opened by lowering the control lever, the lower end of the control lever squeezes the gas tank, and the gas tank releases high-pressure gas through the outlet valve. The high-pressure gas enters the outlet pipe through the outlet valve. One end of the outlet pipe passes through the suction tube and is placed inside the bottle body, releasing gas into the bottle body. The release of gas disturbs the gas flow, thereby reducing liquid stratification. This operation is performed simultaneously with the liquid release and does not affect the extinguishing time, achieving the purpose of disturbing the extinguishing agent inside the fire extinguisher during use.

[0007] Preferably, the bottle body includes a bottle body, a bottle bottom, and a bottle cap. The bottle bottom is installed on one side of the bottle body, and the bottle cap is installed on the other side of the bottle body. A connecting pipe is provided on the bottle body, and the pressing valve is threadedly connected to the connecting pipe. A base is installed on the bottle bottom. The pressing valve has a spray hole with an L-shaped cross-section. A fitting ring is provided inside the spray hole, and the spray hole communicates with the bottle body. The lower end of the control rod is placed inside the spray hole, and an opening and closing block is installed on the lower end of the control rod. A sealing block is installed on the opening and closing block, and the sealing block fits with the fitting ring. The upper end of the control rod passes through the pressing valve and is placed outside the pressing valve. The bottle body is welded together from the bottle body, bottom, and cap into a single unit. A base is installed on the bottom for stable placement of the fire extinguisher. The press valve is connected to the connecting pipe via a threaded connection. The L-shaped nozzle of the press valve connects the bottle body to the outside. The control rod is placed inside the nozzle. An opening and closing block is installed at the lower end of the control rod, and a sealing ring is installed at the upper end of the opening and closing block. When the control rod rises, it pushes the sealing block to fit against the sealing ring, ensuring the sealing performance of the press valve. The upper end of the control rod passes through the press valve and is placed on the outside for pressing to raise and lower the control rod. The part where the control rod passes through the press valve is also sealed. This design improves the sealing performance of the press valve by fitting against the raised surface.

[0008] Preferably, the press valve is equipped with a fixed handle and a press handle, which are rotatably connected to the press valve. The inner side of the press handle corresponds to the upper end of the control lever. A safety pin is installed on the press handle, and a pressure gauge is installed on the press valve. The fixed handle on the press valve is used for holding the fire extinguisher, while the press handle can be rotated. Rotating the press handle lowers the control lever. To prevent accidental activation, a safety pin is installed on the press handle. The press handle can only be rotated after the safety pin is removed. The pressure gauge on the press valve performs real-time pressure monitoring to determine the fire extinguisher's operational status. This design allows for better observation of the fire extinguisher's status by monitoring pressure changes.

[0009] Preferably, the upper end of the straw is fitted with a connector, which is threadedly connected to the press valve. A sealing spring is installed inside the connector, with one end connected to the connector and the other end connected to the opening / closing block. A filter screen is installed at the lower end of the straw. The upper end of the straw is threadedly connected to the press valve via the connector, and the upper end of the sealing spring contacts the opening / closing block, pushing it to tightly engage with the sealing ring. Furthermore, the filter screen installed at the lower end of the straw within the bottle prevents clumping and crystallization of liquids containing various additives. This filter screen prevents lumpy substances from entering the straw and clogging the press valve or damaging the internal structure. This design enhances safety through the installation of the filter screen.

[0010] Preferably, the connector is equipped with a lifting frame, the vent valve is mounted on the lifting frame, a limit frame is mounted on the lifting frame, the gas tank is placed inside the limit frame and slidably connected to the limit frame, the upper end of the vent valve is placed inside the gas tank, a fitting plate is installed on the upper end of the vent valve, a sealing strip is installed on the vent end of the gas tank, the sealing strip is fitted to the fitting plate, the upper side of the gas tank is provided with several circumferentially distributed connecting holes, the upper cross-section of the vent valve is frustum-shaped, the cross-section of the sealing strip is U-shaped, one side of the sealing strip is fitted to the fitting plate, and the side of the vent valve of the sealing strip corresponds to the sealing strip. A lifting frame is installed inside the connector, and an outlet valve corresponding to the gas tank is installed on the lifting frame. A limit frame is installed on the top surface of the lifting frame, and the gas tank is placed inside the limit frame. The limit frame restricts the lifting and lowering stroke of the gas tank. The upper end of the outlet valve is placed at the outlet end of the gas storage pipe. A U-shaped sealing strip is installed at the port of the outlet end. One side of the sealing strip is attached to the fitting plate at the top of the outlet valve to improve the sealing effect. When the gas storage tank is pressed down, the upper end of the outlet valve is inserted into the gas storage tank, and the connecting hole enters the gas storage tank. At this time, the other side of the sealing strip is attached to the side of the frustum-shaped upper end of the outlet valve to seal the outlet end again. At this time, the gas can only enter the outlet valve through the connecting hole. This design allows for better switching of the gas release state through the frustum-shaped upper end of the outlet valve.

[0011] Preferably, the gas storage tank is equipped with a separation spring, one end of which is connected to the gas storage tank and the other end of which is connected to the lifting frame. A pressing rod is installed on the opening and closing block, and the lower end of the pressing rod passes through the lifting frame and contacts the gas storage tank. A partition plate is provided inside the gas storage tank, and an air outlet is provided on the partition plate. An insert rod is provided on the fitting plate, and the insert rod is shaped like a frustum. A sealing rod is installed at the upper end of the insert rod, and the sealing rod matches the air outlet. To prevent the gas tank from descending under no external force, a separation spring is installed on it. The lower end of the separation spring is connected to a lifting frame, which lifts the gas tank. This ensures that the bonding plate can adhere to the sealing strip. However, the sealing performance is insufficient solely due to the bonding plate and sealing strip. Therefore, a partition plate is installed inside the gas tank, with the high-pressure gas located on the side of the partition plate furthest from the bonding plate. An injection valve is installed on the gas tank to inject high-pressure gas. An outlet hole is installed on the partition plate, and an insert rod is installed on the bonding plate. The insert rod is truncated cone-shaped, with its upper diameter smaller than the outlet hole. A sealing rod is installed at the upper end of the insert rod. The sealing rod and the outlet hole seal the airtightness. When the gas tank descends, the sealing rod enters the tank, and the insert rod is inserted into the outlet hole to release the gas. This design further improves the sealing performance through the adhesion between the sealing rod and the partition plate.

[0012] Preferably, the lower end of the vent valve is equipped with several evenly distributed plug-in rings. The upper end of the vent pipe is connected to the vent valve via the plug-in rings, and the lower end of the vent pipe is closed. Several evenly distributed equalizing tubes are installed at the lower end of the vent pipe. One end of each equalizing tube is connected to the vent pipe, and the other end passes through the vent pipe and is placed inside the bottle. The lower end of the vent valve is connected to the straw via a flared plug-in ring to ensure reliable connection. The lower end of the vent pipe is closed, and several evenly distributed equalizing tubes are installed on the vent pipe. Gas is released around the straw through the circumferentially distributed equalizing tubes, thereby agitating the liquid. The gas entering the bottle can also replenish the air pressure inside the bottle. This design can evenly agitate the liquid inside the bottle.

[0013] Preferably, the filter screen is slidably connected to the straw, and a counterweight is provided inside the filter screen. The filter screen is fitted onto the lower end of the straw and can slide on the straw. Filter holes are opened on the side of the filter screen, and a counterweight is installed inside the filter screen. When placed upright, the filter screen descends under the action of the counterweight, allowing filtration through the holes. When the fire extinguisher is inverted, the bottom surface of the filter screen approaches the straw under the action of the counterweight, fitting against the bottom surface of the straw, thereby sealing the lower end of the straw. This design, by sliding the filter screen to seal the lower end of the straw, can prevent damage to the internal structure of the fire extinguisher when it is inverted.

[0014] Preferably, both ends of the nozzle are fitted with clamps, and one end of the nozzle is fitted with a nozzle connector. One end of the nozzle connector is placed inside the spray hole and connected to the press valve. The other end of the nozzle is fitted with a nozzle. A fixing tube is installed on the bottle body, and the nozzle is placed inside the fixing tube. The nozzle is installed at the air outlet end of the spray hole, and clamps are fitted at both ends of the nozzle for easy installation. A nozzle connector is installed at one end of the nozzle, and the nozzle connector is placed inside the spray hole and threadedly connected to the press valve. A nozzle is installed at the other end of the nozzle. When not in use, the nozzle is placed inside the fixing tube to secure the end. This design allows for rapid liquid release via the nozzle.

[0015] Preferably, the nozzle includes a mounting head, a top cap, and a rotating core. One end of the mounting head is placed inside and connected to the nozzle, and the other end is connected to the top cap. The top cap has an atomizing hole. The rotating core is installed inside the atomizing hole and rotatably connected to the top cap. The rotating core has several circumferential atomizing grooves, which are threaded in shape. The mounting head of the nozzle is connected to the nozzle, and the top cap is installed on the mounting head. The rotating core is installed inside the top cap. When the nozzle releases liquid, the liquid passes through the atomizing grooves of the rotating core. The threaded atomizing grooves push the rotating core to rotate. The rapid rotation of the rotating core allows for swirling atomization and uniform spraying of the extinguishing agent, improving extinguishing efficiency. This design atomizes the liquid through the rotation of the rotating core.

[0016] The beneficial effects of this invention are: it can simultaneously agitate the extinguishing agent inside the fire extinguisher during use; the sealing performance of the press valve can be improved by adhering to the raised surface; the status of the fire extinguisher can be better observed by monitoring pressure changes; safety is improved by installing a filter screen; the gas release state can be better switched by the frustum-shaped upper end of the gas outlet valve; the sealing performance can be further improved by adhering the sealing rod to the partition plate; the liquid inside the bottle can be evenly agitated; the lower end of the suction tube can be sealed by the sliding filter screen to prevent damage to the internal structure caused by the fire extinguisher being placed upside down; the liquid can be quickly released through the nozzle; and the liquid can be atomized by the rotation of the rotating core.

[0021] The bottle body 1 includes a bottle body 11, a bottle bottom 12, and a bottle cap 13. The bottle bottom 12 is installed on one side of the bottle body 11, and the bottle cap 13 is installed on the other side of the bottle body 11. A connecting pipe 14 is provided on the bottle body 11, and the press valve 2 is threadedly connected to the connecting pipe 14. A base 15 is installed on the bottle bottom 12. The press valve 2 is provided with a spray hole 22. The cross-sectional shape of the spray hole 22 is L-shaped. A fitting ring 23 is provided inside the spray hole 22.

An opening and closing block 25 is installed on the lower end of the control rod 21. A sealing block 26 is installed on the opening and closing block 25. The sealing block 26 fits with the fitting ring 23. The upper end of the control rod 21 passes through the press valve 2 and is placed outside the press valve 2.

[0022] like Figure 2 As shown, a fixed handle 27 is installed on the press valve 2, and a press handle 28 is installed on the press valve 2. The press handle 28 is rotatably connected to the press valve 2. The inner side of the press handle 28 corresponds to the upper end of the control rod 21.

A filter screen 33 is installed at the lower end of the straw 3.

[0024] like Figure 6As shown, a lifting frame 34 is provided inside the connector 31, and an air outlet valve 6 is installed on the lifting frame 34. A limit frame 35 is installed on the lifting frame 34. The air storage tank 5 is placed inside the limit frame 35 and is slidably connected to the limit frame 35. The upper end of the air outlet valve 6 is placed inside the air storage tank 5. A bonding plate 61 is installed on the upper end of the air outlet valve 6. A sealing strip 51 is installed on the air outlet end of the air storage tank 5. The sealing strip 51 is bonded to the bonding plate 61. Several circumferentially distributed connecting holes 62 are provided on the upper side of the air storage tank 5. The upper cross-sectional shape of the air outlet valve 6 is frustum-shaped. The cross-sectional shape of the sealing strip 51 is U-shaped. One side of the sealing strip 51 is bonded to the bonding plate 61. The side of the air outlet valve 6 of the sealing strip 51 corresponds to the side of the air outlet valve 6.

[0025] The gas storage tank 5 is equipped with a separation spring 54. One end of the separation spring 54 is connected to the gas storage tank 5, and the other end of the separation spring 54 is connected to the lifting frame 34. The opening and closing block 25 is equipped with a pressing rod 251. The lower end of the pressing rod 251 passes through the lifting frame 34 and contacts the gas storage tank 5. The gas storage tank 5 is equipped with a partition plate 52. The partition plate 52 is equipped with an air outlet 53. The fitting plate 61 is equipped with an insert rod 63. The insert rod 63 is shaped like a frustum. The upper end of the insert rod 63 is equipped with a sealing rod 64. The sealing rod 64 matches the air outlet 53.

[0026] The lower end of the vent valve 6 is equipped with several evenly distributed plug rings 65. The upper end of the vent pipe 7 is connected to the vent valve 6 through the plug rings 65. The lower end of the vent pipe 7 is closed. The lower end of the vent pipe 7 is equipped with several distributed equalizing pipes 71. One end of the equalizing pipe 71 is connected to the vent pipe 7, and the other end of the equalizing pipe 71 passes through the vent pipe 7 and is placed inside the bottle body 1.

[0027] The filter screen 33 is slidably connected to the straw 3, and the filter screen 33 is provided with a counterweight 36 inside.

[0028] like Figure 7 , Figure 8 As shown, clamps 41 are installed at both ends of the nozzle 4. A nozzle 4 connector is installed at one end of the nozzle 4. One end of the nozzle 4 connector is placed inside the spray hole 22 and connected to the press valve 2. A nozzle 43 is installed at the other end of the nozzle 4. A fixing tube 16 is installed on the bottle body 1. The nozzle 43 is placed inside the fixing tube 16.

[0029] The nozzle 43 includes a mounting head 44, a top cap 45, and a rotating core 46. One end of the mounting head 44 is placed inside the nozzle 4 and connected to the nozzle 4, and the other end of the mounting head 44 is connected to the top cap 45. The top cap 45 is provided with an atomizing hole 47. The rotating core 46 is installed inside the atomizing hole 47 and is rotatably connected to the top cap 45. The rotating core 46 is provided with a plurality of circumferential atomizing grooves 48, and the atomizing grooves 48 are threaded.

[0030] When using this fire extinguisher, pressing the handle 28 rotates the control lever 21, causing it to descend. The opening and closing block 25 at the lower end of the control lever 21 carries the sealing block 26 away from the fitting ring 24, opening the spray hole 22 of the pressing valve 2. The extinguishing agent in the bottle 1 enters the suction tube 3 under the pressure of high-pressure gas. The filter screen 33 at the lower end of the suction tube 3 filters the incoming extinguishing agent to prevent internal blockage. The extinguishing agent passes through the suction tube 3 and the spray hole 22 in sequence and then enters the nozzle 4. The extinguishing agent enters the nozzle 43 and is then ejected through the atomizing hole 47. In the atomizing hole 47, the extinguishing agent impacts the atomizing groove 48, causing the rotating core 46 to rotate rapidly. The rotation of the rotating core 46 atomizes and evenly sprays the extinguishing agent, improving the extinguishing efficiency.

[0031] When the extinguishing agent is sprayed, the control lever 21 descends, causing the squeezing lever 251 to descend as well. The lower end of the squeezing lever 251 passes through the limiting frame 35 and squeezes the gas storage tank 5 down along the limiting frame 35. The upper end of the outlet valve 6 is inserted into the gas storage tank 5, and the connecting hole 62 enters the gas storage tank 5. At this time, the other side of the sealing strip 51 is in contact with the frustum-shaped upper side of the outlet valve 6, sealing the outlet end again. At this time, the gas can only enter the outlet valve through the connecting hole 62. Simultaneously, the sealing lever 64 enters the gas storage tank 5, and the insertion lever 63 is inserted into the outlet hole 53 to release the gas. The high-pressure gas on one side of the partition plate 52 enters the outlet end and then enters the outlet valve 6 through the connecting hole 62. High-pressure gas enters the outlet pipe 7 through the inlet valve 6. Several evenly distributed equalization pipes 71 are installed on the outlet pipe 7. Gas is released around the suction pipe 3 through the circumferentially distributed equalization pipes 71, thereby disturbing the liquid and reducing the stratification of the internal extinguishing agent. The gas entering the cylinder 1 can also replenish the gas pressure inside the cylinder 1 and ensure the internal pressure is stable.

[0032] During use, in order to prevent the bottle 1 from being inverted, a counterweight 36 is installed on the filter screen 33. When placed upright, the filter screen 33 is lowered by the counterweight 36, and at this time, it can be filtered through the holes. When the fire extinguisher is inverted, the bottom surface of the filter screen 33 approaches the straw 3 and fits against the bottom surface of the straw 3 under the action of the counterweight 36, thereby sealing the lower end of the straw 3.
