Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, specifically to an intelligent fire extinguisher. Background Technology

[0002] Dry powder fire extinguishers contain ammonium phosphate or sodium bicarbonate dry powder and pressurized nitrogen. The compressed nitrogen in the cylinder slowly leaks over time, causing the cylinder pressure to gradually decrease. When the pressure drops to a certain level, the fire extinguisher becomes unusable. To ensure proper functioning, staff need to inspect the extinguishers monthly and record the results, making it difficult to detect abnormal pressure issues promptly. Furthermore, fire extinguishers require immediate use, so anti-theft measures are often lacking, leading to the possibility of unauthorized movement or loss. Overall, the management of fire extinguishers is inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent fire extinguisher to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intelligent fire extinguisher, comprising a steel cylinder, a valve body installed on the steel cylinder, the valve body having a handle, and a spray pressure handle rotatably mounted on the handle;

[0005] The bottom shell is installed on the side of the handle. A main board is installed inside the bottom shell. A battery is electrically connected to the lower surface of the main board. The battery is located inside the bottom shell. A pressure sensor, a communication module, and a positioning module are electrically connected to the main board.

[0006] The pressure sensor probe is connected to the valve body. The pressure sensor detects the internal pressure of the cylinder, eliminating the need for manual inspection of the fire extinguishers and making fire extinguisher management more convenient and faster. The positioning module detects the position of the cylinder, making it easier to find the fire extinguishers and also helps to locate them to prevent loss. The detection results of the pressure sensor and positioning module are transmitted to the cloud platform through the communication module for remote management. Managers can remotely monitor the status of all fire extinguishers in batches through the backend, improving management efficiency.

[0007] Furthermore, the handle and the spray handle are provided with a socket, into which a safety pin is inserted. The safety pin can lock the spray handle to prevent the fire extinguishing agent from being accidentally sprayed in non-emergency scenarios (such as personnel collisions or accidental contact with the handle during handling). This reduces the waste of fire extinguishing agent and avoids unnecessary impacts on personnel and the environment caused by accidental spraying.

[0008] Furthermore, a face cover is installed on the bottom shell, and a display screen is installed on the face cover. The display screen is electrically connected to the motherboard and can display the core status of the fire extinguisher in real time (such as current pressure value, battery level, location information, and device number), so that on-site personnel can directly and quickly determine whether the fire extinguisher is normal without relying on the cloud platform.

[0009] Furthermore, the valve body is connected to a nozzle, and the end of the nozzle is connected to a horn nozzle. The nozzle can extend the spray distance of the extinguishing agent and prevent the user from coming into close contact with the flames. The horn nozzle can disperse the extinguishing agent into a more uniform spray range (or enhance the directional spray force), adapting to different fire scenarios (such as concentrated spraying for small electrical fires and expanded coverage for large solid fires), thus improving fire extinguishing efficiency.

[0010] Furthermore, the motherboard is electrically connected to a three-axis accelerometer. The three-axis accelerometer monitors whether the fire extinguisher has been moved, knocked over, or illegally removed. If the fire extinguisher is tilted, the three-axis accelerometer can trigger an early warning, reminding the management personnel to right it in time to avoid damage to the fire extinguisher and ensure its emergency use. If the fire extinguisher is far from the designated storage point, the three-axis accelerometer, in conjunction with the positioning module, can send abnormal information to the cloud platform through the communication module. The management personnel can quickly track it, prevent the fire extinguisher from being lost, and ensure full coverage of fire-fighting points.

[0011] Furthermore, the motherboard is electrically connected to an NFC tag. When a mobile phone is brought close to the NFC tag, the status information of the fire extinguisher can be read. The inspection personnel can quickly read the status of the fire extinguisher (such as pressure, power, and last inspection time) with just their mobile phone, without the need for manual recording, thus avoiding errors caused by manual recording. Moreover, the data can be directly synchronized to the cloud platform to achieve paperless inspection.

[0012] Furthermore, the mainboard is electrically connected to a buzzer and an indicator light. The bottom shell has a light hole, and the indicator light is located inside the light hole. By checking the status of the indicator light, any abnormality of the fire extinguisher can be detected in time. The cover has a sound outlet corresponding to the buzzer. The sound outlet will not block the sound of the buzzer, making it easy for passersby to notice in time.

[0013] Furthermore, the motherboard is electrically connected to a charging port, and the bottom shell is provided with an insertion port. The charging port is located inside the insertion port, which can conveniently replenish the battery, prevent the intelligent monitoring function from failing due to the battery being depleted, and maintain the battery's healthy state.

[0014] Furthermore, the charging port is a Type-C port, compatible with common chargers such as mobile phones and tablets, eliminating the need for an additional dedicated charger and reducing charger adaptation costs. The communication module is NB-IoT, solving the problems of weak and easily disconnected traditional Wi-Fi / Bluetooth signals and ensuring stable data transmission.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The pressure inside the cylinder is detected in real time by the pressure sensor. When the pressure inside the cylinder is insufficient, the communication module sends the insufficient pressure information to the cloud platform, which can notify the management personnel to check in time and ensure that the fire extinguisher is always available.

[0017] (2) Staff can view the location, status and inspection records of all fire extinguishers through the cloud platform, realizing paperless and traceable refined management of fire extinguishers, making fire extinguisher management more convenient.

[0018] (3) The fire extinguisher can be located through the positioning module. When the fire extinguisher is moved abnormally or leaves the preset electronic fence area, the communication module will immediately alarm the cloud platform to effectively prevent the fire extinguisher from being lost. In case of fire, it can remotely and quickly guide personnel to the nearest and effective fire extinguisher location, so that the fire can be extinguished more promptly. Attached Figure Description

[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] Example:

[0025] Please see Figure 1-3This utility model provides a technical solution: an intelligent fire extinguisher, including a steel cylinder 1, a valve body 19 installed on the steel cylinder 1, a handle 2 on the valve body 19, and a spray handle 3 rotatably installed on the handle 2;

[0026] The bottom shell 5 is mounted on the side of the handle 2. The bottom shell 5 is made of PC material. The motherboard 18 is installed inside the bottom shell 5. The motherboard 18 has a microprocessor (MCU). The MCU can be an STM32L051C8T6 (ARM Cortex-M0+ core), which has ultra-low power consumption characteristics, supports multi-channel ADC acquisition and UART / I2C interface, and can meet the sensor data processing and communication module 15 driving requirements.

[0027] The motherboard 18 is electrically connected to a battery 12 on its lower surface. The battery 12 is located inside the bottom shell 5 and is a long-life lithium battery. The motherboard 18 is electrically connected to a pressure sensor 14, a communication module 15, and a positioning module 16. The communication module 15 (such as NB-IoT, LoRa, 4G / 5G) is responsible for wirelessly transmitting the collected data to the cloud platform. NB-IoT is the preferred choice in this embodiment due to its low power consumption, wide coverage, and large connectivity. The NB-IoT module BC95-G is selected, which supports the 3GPP R14 standard.

[0028] The pressure sensor 14 can be an MS5803-01BA, with a measurement range of 0-14 bar. The probe of the pressure sensor 14 is connected to the inside of the valve body 19 through a miniature copper pressure-conducting tube to ensure the accuracy of pressure detection.

[0029] The positioning module 16 can be an ATGM336H-5N31 (GPS + Beidou dual-mode), with a positioning accuracy of 2.5m and support for low power consumption mode (standby current < 10mA).

[0030] The probe of the pressure sensor 14 is connected to the valve body 19. The pressure sensor 14 detects the internal pressure of the gas cylinder 1, and the positioning module 16 detects the position of the gas cylinder 1. The detection results of the pressure sensor 14 and the positioning module 16 are transmitted to the cloud platform through the communication module 15, so that the pressure, position and other information of the gas cylinder 1 can be viewed remotely without having to manually check the gas cylinder 1 frequently.

[0031] In this embodiment, as Figure 1 As shown, the handle 2 and the spray handle 3 are provided with insertion holes, and a safety pin 4 is inserted into the insertion holes. Before using the fire extinguisher, the safety pin 4 needs to be removed before the spray handle 3 can be pressed smoothly. This can prevent the spray handle 3 from being accidentally triggered and avoid accidental spraying of the extinguishing agent.

[0032] In this embodiment, as Figure 3As shown, a cover 8 is installed on the bottom shell 5. The cover 8 is made of PC material and a display screen 13 is installed on the cover 8. The display screen 13 is electrically connected to the motherboard 18. The display screen 13 is a touch screen and can display simple operation instructions (such as "pressure normal" and "please charge"), which reduces the usage threshold for non-professionals. Especially in emergency scenarios, it helps users quickly obtain key information, making it easier to check the status of the fire extinguisher on site and also to check the battery level of the battery 12.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the valve body 19 is connected to a nozzle 6, and the end of the nozzle 6 is connected to a horn nozzle 7. The nozzle 6 can be bent and its angle adjusted to facilitate aiming at the source of the fire, such as narrow gaps or flames inside equipment. The horn nozzle 7 can expand the spray range of the extinguishing agent and prevent the extinguishing agent from spreading too much, which would reduce the extinguishing efficiency.

[0034] In this embodiment, as Figure 3 As shown, the motherboard 18 is electrically connected to a triaxial accelerometer 17. The triaxial accelerometer 17 monitors whether the fire extinguisher is moved, knocked over, or illegally removed. The triaxial accelerometer 17 can be a LIS3DH, supporting ±2 / ±4 / ±8 / ±16g ranges, and can detect movement and tilting (angle threshold can be set). Its power consumption is as low as 2μA (in sleep mode), making it suitable for long-term monitoring.

[0035] In this embodiment, as Figure 3 As shown, the motherboard 18 is electrically connected to an NFC tag 22. When a mobile phone is brought close to the NFC tag 22, it reads the status information of the fire extinguisher. The NFC tag 22 can be an NT3H2111W0FHK, which supports the ISO14443A protocol and has a storage capacity of 1KB. Even when the network signal is weak (such as in underground garages or basements) or the cloud platform fails, the status information stored locally can still be read via NFC, ensuring that the inspection work is not interrupted. The NFC tag can store the unique identifier of the fire extinguisher, such as the factory number, production date, and shelf life, which facilitates the tracking of the entire life cycle of the fire extinguisher and makes fire extinguisher management more convenient.

[0036] In this embodiment, as Figure 3As shown, the mainboard 18 is electrically connected to a buzzer 9 and an indicator light 10. The bottom shell 5 has a light hole 20, and the indicator light 10 is located inside the light hole 20. The cover 8 has a sound outlet corresponding to the buzzer 9. The indicator light 10 (red indicates abnormal pressure, yellow indicates low battery power of battery 12) quickly attracts the attention of on-site personnel through visual signals. The buzzer 9 effectively transmits information through sound signals (intermittent beeping to indicate abnormality) to avoid the visual signals being ignored. The abnormality type can be distinguished by different light colors (red / yellow / green) and beeping frequencies (fast / slow / long beeping) (such as insufficient pressure is an emergency warning, and low battery power of battery 12 is a regular warning), helping managers to prioritize high-risk issues.

[0037] In this embodiment, as Figure 3 As shown, the motherboard 18 is electrically connected to a charging port 11, and the bottom shell 5 is provided with a socket 21. The charging port 11 is located inside the socket 21. The charging port 11 is a Type-C port. The Type-C port has no right or wrong orientation, making it more convenient to use and avoiding damage to the interface due to reverse insertion.

[0038] Specifically, during use, the pressure sensor 14 detects the air pressure in the valve body 19, obtains the real-time pressure value inside the cylinder 1, and converts the analog signal into a digital signal to be transmitted to the MCU. When the pressure is lower than the threshold (e.g., < 1.0 MPa), an abnormal warning is triggered.

[0039] The positioning module 16 locates the fire extinguishers and transmits positioning data to the MCU every hour and minute (configurable) to determine the deployment location of the fire extinguishers. In the moving state (triggered by the acceleration sensor), the positioning frequency increases to once per minute, effectively preventing fire extinguisher loss.

[0040] The three-axis accelerometer 17 detects the posture of the gas cylinder 1 in real time. When the gas cylinder 1 falls over, the three-axis accelerometer 17 transmits the tilting information of the gas cylinder 1 to the MCU. The MCU receives the data from the pressure sensor 14, the positioning module 16, and the three-axis accelerometer 17, and compares it with a preset value. When the data is abnormal, the MCU controls the communication module 15 to work. The communication module 15 sends the pressure value, power, positioning information, posture of the gas cylinder 1, and other information to the cloud platform.

[0041] The cloud platform displays the location and real-time status of all fire extinguishers, featuring precise electronic map points for easy remote management. This technology can be applied in: 1. Data centers / server rooms: high-value assets with significant fire damage. 2. Large commercial complexes / shopping malls: densely populated areas with numerous fire extinguishers, posing significant management challenges. 3. Museums / archives: housing irreplaceable and precious cultural heritage. 4. Chemical plants / power plants: high-risk environments requiring the highest level of safety monitoring. 5. High-end office buildings / hotels: seeking intelligent management to enhance property quality.

[0042] 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.
