Description

Technical Field

[0001] This utility model relates to the technical field of battery fire extinguishing devices, specifically a handheld jet-type lithium battery fire extinguishing device. Background Technology

[0002] Battery-powered fire extinguishing devices are modern fire-fighting equipment that combines portability, high efficiency, and safety. They are mainly powered by built-in batteries and quickly extinguish fires by spraying extinguishing agents. The devices are compact, easy to carry, and suitable for various emergency fire scenarios.

[0003] According to a search, Chinese patent document, publication number CN220546497U, discloses a pressureless handheld water-based foam fire extinguishing device, including a main body and a puncture mechanism. The main body includes a lower shell and an upper shell. A pressure plate is installed inside the upper shell, and a handle is installed at the right end of the lower shell. A mounting frame is installed inside the lower shell, and a separation mechanism is installed on the mounting frame. The puncture mechanism is connected to the middle of the upper shell. Its advantages are: through the existence of the main body and the separation mechanism, the two solvents of the water-based foam fire extinguishing agent can be separated and stored, thereby achieving pressureless storage of the foam fire extinguishing agent, reducing the influence of external factors on the water-based foam fire extinguishing device. At the same time, in conjunction with the work of the puncture mechanism, the two solvents that can react in the foam fire extinguishing device can be directly mixed, avoiding the labor burden caused to the user by the traditional fire extinguishing device requiring inversion to mix the foam fire extinguishing agent. The function is more comprehensive, facilitating the promotion and use of the product.

[0004] However, the above technologies still have certain shortcomings. For example, the installation of the upper and lower housings usually uses elastic rubber gaskets to ensure the sealing of the connection between the connecting rod and the pressure plate, thereby preventing solvents in the lower housing, especially major solvents such as UPA special fire extinguishing materials, from leaking into the upper housing. However, after long-term use, the elastic rubber gaskets will inevitably wear down, leading to a decrease in sealing performance. Furthermore, there is a lack of an effective alarm mechanism, making it impossible for users to know the installation status of the upper and lower housings in a timely manner or to detect potential leakage hazards. In this case, if the fire extinguishing agent leaks accidentally, it will not only affect the normal use of the fire extinguishing device but may also pose a safety hazard. To address these issues, we provide a handheld jet-type lithium battery fire extinguishing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a handheld spray type lithium battery fire extinguishing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a handheld spray type lithium battery fire extinguishing device, comprising a cylinder, a top cover threadedly connected to the upper end of the cylinder, and a warning mechanism provided inside the cylinder. A support plate is fixedly connected to the inner wall of the top cover, and a battery body and a delivery pump are fixedly connected to the top of the support plate respectively. A siphon tube is fixedly connected to the inlet of the delivery pump, and a delivery pipe is fixedly connected to the outlet of the delivery pump. A nozzle is fixedly connected to one end of the delivery pipe, and a set of symmetrical adjustment mechanisms is provided inside the nozzle. A handle is fixedly connected to the outer wall of the top cover, and a control switch is provided inside the handle. A controller is fixedly connected to the outer wall of the top cover, and an indicator light and a speaker are provided on one side of the controller. The indicator light and the speaker are electrically connected to the controller. The control switch, the battery body, and the delivery pump are all electrically connected to the controller.

[0007] The aforementioned warning mechanism includes a mounting ring, a threaded block, a spring, and a pressure block. One end of the mounting ring is fixedly connected to one end of the threaded block, and the other end of the threaded block is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to one end of the pressure block.

[0008] As described above, the end of the mounting ring away from the threaded block is fixedly connected to one end of the cylinder, and the outer wall of the threaded block is threadedly connected to the inner wall of the top cover.

[0009] As described above, the outer wall of the siphon tube is movably connected to the inside of the pressure block, and a pressure sensor is attached to the top surface of the pressure block. One end of the pressure sensor is fixedly connected to the bottom end of the support plate, and the pressure sensor is electrically connected to the controller.

[0010] The aforementioned adjusting mechanism includes sector plates, rotating rods, and gears. The interiors of the two sector plates are fixedly connected to the outer walls of the two rotating rods, and the outer walls of the two rotating rods are fixedly connected to the interiors of the two gears, which mesh with each other.

[0011] As mentioned above, the outer walls of the two fan-shaped plates are tightly attached to the inner wall of the upper cover, and both ends of the rotating rod are rotatably connected to the inner wall of the nozzle.

[0012] As mentioned above, a knob is fixedly connected to one end of the rotating rod, and the knob is located outside the nozzle.

[0013] Compared with existing technologies, this handheld jet-type lithium battery fire extinguishing device has the following advantages:

[0014] I. This utility model, through its alarm mechanism and precise controller settings, adjusts the pressure sensor to a specified pressure value. Then, by rotating the cylinder, the threaded block rotates along with the mounting ring. During this process, the spring is moderately compressed, pushing the pressure block tightly against the pressure sensor. The pressure sensor accurately receives the pressure signal from the pressure block and quickly transmits it to the controller for efficient processing. If the signal data is within the preset range, it indicates that the cylinder and top cover are perfectly installed. Conversely, if the data exceeds or falls below the specified value, the controller will immediately activate the speaker to sound an alarm, promptly reminding the user of any potential hazards in the installation of the cylinder and top cover. This effectively prevents accidental leakage of the extinguishing agent inside the cylinder, ensuring the safety and stability of the equipment.

[0015] II. Through the adjustment mechanism, this utility model allows for precise fire extinguishing operations. Simply pressing the control switch sends an electrical signal to the controller, which then instructs the battery to power the delivery pump. The pump then starts, and as it operates, the extinguishing agent inside the cylinder is effectively delivered to the nozzle via the siphon and delivery pipe, achieving accurate and efficient fire extinguishing. Finally, to adjust the spray range, rotating the knob rotates one of the levers. Since the two gears mesh, the other gear drives the other lever to rotate in the opposite direction, causing the two fan-shaped blades to open or close. By controlling the degree of fan-shaped blade opening, the spray range of the nozzle can be precisely reduced or expanded to meet the spraying needs of different scenarios.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a handheld spray type lithium battery fire extinguishing device, including a cylinder 1, a top cover 2 threadedly connected to the upper end of the cylinder 1, and a warning mechanism 8 provided inside the cylinder 1. A support plate 3 is fixedly connected to the inner wall of the top cover 2, and a battery body 4 and a delivery pump 5 are fixedly connected to the top of the support plate 3 respectively. A siphon tube 6 is fixedly connected to the inlet of the delivery pump 5, and a delivery pipe 7 is fixedly connected to the outlet of the delivery pump 5. A nozzle 10 is fixedly connected to one end of the delivery pipe 7, and a set of vertically symmetrical adjustment mechanisms 9 are provided inside the nozzle 10. A handle 11 is fixedly connected to the outer wall of the top cover 2, and a control switch 12 is provided inside the handle 11. A controller 13 is fixedly connected to the outer wall of the top cover 2, and an indicator light 14 and a speaker 15 are provided on one side of the controller 13. The indicator light 14 and the speaker 15 are both electrically connected to the controller 13. The control switch 12, the battery body 4, and the delivery pump 5 are all electrically connected to the controller 13.

[0025] First, the pressure sensor 16 is adjusted to the specified pressure data through precise settings on the controller 13. Then, the cylinder 1 is rotated, and with the help of the warning mechanism 8, the warning mechanism 8 is tightly attached to the pressure sensor 16. At this time, the pressure sensor 16 accurately receives the pressure signal from the warning mechanism 8 and quickly transmits the signal to the controller 13 for efficient processing. If the signal data is within the preset specified range, it indicates that the installation of the cylinder 1 and the top cover 2 is perfect. Conversely, if the data exceeds or falls below the specified value, the controller 13 will immediately activate the speaker 15 to sound an alarm, promptly reminding the user that there is a potential hazard in the installation of the cylinder 1 and the top cover 2, thereby effectively preventing accidental leakage of the extinguishing agent inside the cylinder 1 and ensuring the safety and stability of the equipment. Second, if the battery body 4 has insufficient power, the control indicator light 14 on the controller 13 will display a red light. Once charging is complete, indicator light 14 will display a green light. Under normal conditions, indicator light 14 is in the off state, thus promptly reminding the user of the battery body 4's power status and preventing long-term power depletion, thereby extending the battery body 4's service life. Subsequently, during fire extinguishing operations, simply press the control switch 12. This action quickly transmits an electrical signal to the controller 13. Upon receiving the signal, the controller 13 instructs the battery body 4 to supply power to the delivery pump 5, which then starts. As the delivery pump 5 operates, the fire extinguishing agent in the cylinder 1 is effectively delivered to the nozzle 10 through the siphon pipe 6 and the delivery pipe 7, thereby achieving precise and efficient fire extinguishing. Finally, to adjust the spray range, rotate the adjustment mechanism 9. The adjustment mechanism 9 controls the spray range of the nozzle 10 by adjusting its degree of expansion, thus reducing or expanding the spray range of the nozzle 10 to meet the spraying needs in different scenarios.

[0026] like Figure 1-3 As shown, the warning mechanism 8 includes a mounting ring 801, a threaded block 802, a spring 803, and a pressure block 804. One end of the mounting ring 801 is fixedly connected to one end of the threaded block 802, and the other end of the threaded block 802 is fixedly connected to one end of the spring 803. The other end of the spring 803 is fixedly connected to one end of the pressure block 804. The end of the mounting ring 801 away from the threaded block 802 is fixedly connected to one end of the cylinder 1. The outer wall of the threaded block 802 is threadedly connected to the inner wall of the upper cover 2. The outer wall of the siphon tube 6 is movably connected to the inside of the pressure block 804. The top surface of the pressure block 804 is in close contact with a pressure sensor 16. One end of the pressure sensor 16 is fixedly connected to the bottom end of the support plate 3, and the pressure sensor 16 is electrically connected to the controller 13.

[0027] By precisely setting the controller 13, the pressure sensor 16 is adjusted to the specified pressure data. Then, the cylinder 1 is rotated, and the threaded block 802 rotates accordingly with the help of the mounting ring 801. During this process, the spring 803 is moderately compressed, which pushes the pressure block 804 to fit tightly against the pressure sensor 16. At this time, the pressure sensor 16 accurately receives the pressure signal from the pressure block 804 and quickly transmits the signal to the controller 13 for efficient processing. If the signal data is within the preset specified range, it indicates that the installation of the cylinder 1 and the top cover 2 has reached a perfect state. Conversely, if the data exceeds or falls below the specified value, the controller 13 will immediately activate the speaker 15 to sound an alarm, promptly reminding the user that there is a potential hazard in the installation of the cylinder 1 and the top cover 2, thereby effectively preventing accidental leakage of the extinguishing agent in the cylinder 1 and ensuring the safety and stability of the equipment.

[0028] like Figure 1 , Figure 4 and Figure 5 As shown, the adjustment mechanism 9 includes sector-shaped plates 901, rotating rods 902, and gears 903. The interiors of the two sector-shaped plates 901 are fixedly connected to the outer walls of the two rotating rods 902, and the outer walls of the two rotating rods 902 are fixedly connected to the interiors of the two gears 903. The two gears 903 mesh with each other. The outer walls of the two sector-shaped plates 901 are in close contact with the inner wall of the upper cover 2. Both ends of the rotating rod 902 are rotatably connected to the inner wall of the nozzle 10. A knob 17 is fixedly connected to one end of the rotating rod 902, and the knob 17 is located outside the nozzle 10.

[0029] During fire extinguishing, simply press the control switch 12. This action quickly transmits an electrical signal to the controller 13. Upon receiving the signal, the controller 13 instructs the battery body 4 to supply power to the delivery pump 5. The delivery pump 5 then starts. As the delivery pump 5 operates, the fire extinguishing agent in the cylinder 1 is effectively delivered to the nozzle 10 through the siphon pipe 6 and the delivery pipe 7, thereby achieving precise and efficient fire extinguishing. Finally, to adjust the spray range, turn the knob 17, causing one of the rotating rods 902 to rotate. Since the two gears 903 are meshed, the other gear 903 drives the other rotating rod 902 to rotate in the opposite direction, thereby causing the two fan-shaped blades 901 to open or close. By controlling the degree of opening of the fan-shaped blades 901, the spray range of the nozzle 10 can be precisely reduced or expanded to meet the spraying needs in different scenarios.

[0030] Working Principle: First, the pressure sensor 16 is adjusted to the specified pressure value through precise settings by the controller 13. Then, the cylinder 1 is rotated, and the threaded block 802 rotates accordingly with the help of the mounting ring 801. During this process, the spring 803 is moderately compressed, which pushes the pressure block 804 to fit tightly against the pressure sensor 16. At this time, the pressure sensor 16 accurately receives the pressure signal from the pressure block 804 and quickly transmits the signal to the controller 13 for efficient processing. If the signal data is within the preset specified range, it indicates that the installation of the cylinder 1 and the top cover 2 is perfect. Conversely, if the data exceeds or falls below the specified value, the controller 13 will immediately activate the speaker 15 to sound an alarm, promptly reminding the user that there is a potential problem with the installation of the cylinder 1 and the top cover 2. Secondly, if the battery body 4 has insufficient power, the control indicator light 14 on the controller 13 will show a red light. If the battery body 4 has been charged... When the operation is complete, indicator light 14 will show a green light. Under normal conditions, indicator light 14 is in the off state, thus promptly reminding the user of the battery status of the main body 4. Subsequently, during the fire extinguishing operation, simply press the control switch 12. This action will quickly transmit an electrical signal to the controller 13. Upon receiving the signal, the controller 13 instructs the main body 4 to supply power to the delivery pump 5, and the delivery pump 5 will start. As the delivery pump 5 operates, the fire extinguishing agent in the cylinder 1 is effectively delivered to the nozzle 10 through the siphon pipe 6 and the delivery pipe 7, thereby achieving precise and efficient fire extinguishing. Finally, to adjust the spray range, turn the knob 17, causing the knob 17 to drive one of the rotating rods 902 to rotate. Since the two gears 903 are meshed, the other gear 903 drives the other rotating rod 902 to rotate in the opposite direction, thereby causing the two fan-shaped blades 901 to open or close. By controlling the degree of opening of the fan-shaped blades 901, the spray range of the nozzle 10 can be controlled.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
