Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a fire extinguisher with fire source detection function. Background Technology

[0002] Fire, as one of the major disasters endangering public safety, is characterized by its suddenness and rapid spread, seriously threatening people's lives and property. Traditional portable fire extinguishers rely on personnel manually searching for and operating them after discovering a fire. However, in actual fire scenes, dense smoke, high temperatures, and toxic gases are often present. Non-professionals, in a state of panic, find it difficult to quickly and accurately locate fire extinguishers and are prone to getting lost, thus missing the best opportunity to extinguish the fire.

[0003] Furthermore, even if a fire is discovered and a fire extinguisher is retrieved, ordinary personnel, lacking professional fire safety training, may not be able to master the correct spray angle and distance, leading to low or even ineffective firefighting efficiency. Meanwhile, traditional fire extinguishers cannot actively detect fires and issue early warnings in their initial stages, nor can they achieve remote monitoring and intelligent response. Therefore, there is an urgent need for an intelligent fire extinguisher that can automatically detect fire sources, intelligently assess fire conditions, possess attitude calibration functions, and be remotely monitored, to address the problems of slow response, high operational barriers, and low firefighting efficiency inherent in existing technologies. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a fire extinguisher with fire source detection function.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fire extinguisher with fire source detection function, characterized in that it comprises: a fire extinguisher body filled with extinguishing medium; a fire source detection module disposed on the fire extinguisher body for detecting ambient fire and generating a detection signal; a control system electrically connected to the fire source detection module for receiving and judging the fire situation based on the detection signal and generating a control command; and an actuator connected to the control system for receiving the control command and triggering the fire extinguisher body to release the extinguishing medium.

[0006] Preferably, the fire source detection module includes at least one of the following sensors: a flame sensor, a temperature sensor, an infrared sensor, an ultraviolet sensor, and a smoke sensor.

[0007] Preferably, the control system includes: a signal processing unit for filtering and amplifying the detection signal; a microcontroller unit for comparing the processed detection signal with a preset threshold to determine whether a fire has occurred; and a drive circuit for generating control commands to drive the actuator after confirming a fire.

[0008] Preferably, the system further includes an alarm module, which is electrically connected to the control system and is used to issue audible, visual, and wireless remote alarm signals when the fire source detection module detects a fire.

[0009] Preferably, it also includes a manual trigger switch, which is electrically connected to the control system and the actuator for manually forcibly initiating fire extinguishing.

[0010] Preferably, the actuator is an electric needle valve, a solenoid valve, or an electric rotary valve, which is configured to puncture or open the sealing mechanism of the fire extinguisher body upon receiving a control command.

[0011] Preferably, the system further includes an attitude sensor electrically connected to the control system for detecting the usage attitude of the fire extinguisher body; the control system is configured to allow or trigger the actuator to operate only when the attitude sensor detects that the fire extinguisher is in a predetermined fire extinguishing spray attitude.

[0012] Preferably, it also includes a power module for supplying power to the fire source detection module, control system and actuator; the power module is a rechargeable battery and is equipped with an external charging interface or a solar charging panel.

[0013] Preferably, the fire extinguisher body has a mounting bracket on its outer shell, and the fire source detection module is mounted on the mounting bracket through a universal adjustment structure to adjust its detection direction and angle.

[0014] Preferably, the control system further includes a wireless communication module for sending fire information and equipment status information to a remote monitoring terminal and receiving control commands from the remote monitoring terminal.

[0015] The advantages of this invention compared to existing technologies are: 1. This invention integrates a fire source detection module composed of multiple sensors, combined with signal processing and data fusion algorithms, to proactively and in real-time monitor environmental fire conditions, realizing a shift from "passive waiting" to "proactive detection," and significantly shortening fire response time.

[0016] 2. In addition to automatic detection, it also retains a manual trigger switch to ensure manual intervention capability in case of automatic system failure or emergency; at the same time, the introduction of a posture sensor ensures that the fire extinguisher can only be activated under the correct spray posture, avoiding fire extinguishing failure due to improper operation.

[0017] 3. The control system can fuse and analyze data from multiple sensors to accurately determine the fire situation; the actuators respond quickly, and in conjunction with the remote monitoring terminal, it realizes the intelligent and efficient fire extinguishing process, thereby improving the success rate of fire extinguishing.

[0018] 4. The integrated wireless communication module gives the fire extinguisher Internet of Things (IoT) attributes, allowing managers to receive alarm information in real time and remotely view the equipment status, facilitating centralized management and timely dispatch.

Detailed Implementation

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 8 As shown, the technical solution of the present invention is: a fire extinguisher with fire source detection function, mainly including a fire extinguisher body, a mounting bracket and adjustment structure, a fire source detection module, a manual trigger switch, a power supply module, an attitude sensor, an alarm module, a wireless communication module, a control system and an actuator.

[0024] The fire extinguisher body serves as the carrier and extinguishing medium storage unit for the entire system, and is filled with extinguishing medium. To adapt to different installation environments, the fire extinguisher body has a mounting bracket on its outer shell, and the fire source detection module is mounted on this bracket via a universal adjustment structure. This design allows for flexible adjustment of the detection direction and angle of the fire source detection module, ensuring comprehensive coverage of the monitored area.

[0025] The fire source detection module, mounted on the fire extinguisher body, is the core component of this system for sensing the external environment. In this embodiment, the fire source detection module integrates at least one of a flame sensor, a temperature sensor, an infrared sensor, an ultraviolet sensor, and a smoke sensor. These sensors work together to monitor the environment from multiple dimensions, including temperature, spectrum, and smoke concentration.

[0026] The control system is electrically connected to the fire source detection module. The control system receives and determines the fire situation based on the detection signal, and generates control commands. It includes a signal processing unit, a microcontroller unit (MCU), and a drive circuit.

[0027] The actuator is connected to the control system and is used to receive the control command and trigger the fire extinguisher body to release the extinguishing medium. In this embodiment, the actuator is preferably an electric needle valve or a solenoid valve, which is configured to puncture or open the sealing mechanism of the fire extinguisher body after receiving the control command.

[0028] The workflow of this invention begins with "environmental monitoring startup". After the system is powered on, it automatically enters the environmental monitoring state. Subsequently, it enters the "multi-sensor data acquisition" stage, where various sensors in the fire source detection module work synchronously to collect raw environmental data.

[0029] The acquired raw signal enters the "signal filtering and amplification" stage. Since the signal output by the sensor is often weak and easily affected by environmental electromagnetic interference, the signal processing unit in the control system filters and amplifies the detected signal to extract the effective feature signal.

[0030] The pre-processed signals then enter the "data fusion analysis" stage. The microcontroller unit uses a specific algorithm to comprehensively analyze multi-source data to improve the accuracy of fire assessment and reduce the false alarm rate.

[0031] After data fusion and analysis are completed, the system enters the critical judgment node: "Has the threshold been exceeded?". The microcontroller compares the processed detection signal with the preset fire threshold. If the judgment result is "no", the process returns to the "continue monitoring" state, and the system remains on alert; if the judgment result is "yes", the system "confirms the fire signal" and "sends the signal to the control system", preparing to proceed to the next step of the handling process.

[0032] When the control system receives a fire signal, it first performs a secondary verification in the signal processing unit, taking into account any possible "manual signal reception". Subsequently, the microcontroller unit judgment module starts working and performs a logical judgment of "fire confirmation?".

[0033] If the microcontroller determines the result as "no", the system will "return to the monitoring loop" and wait for the next data acquisition. If the result is "yes", the system will not immediately initiate fire suppression, but will first "check the attitude sensor".

[0034] An attitude sensor is used to detect the usage attitude of the fire extinguisher body. The control system is configured to only allow the actuator to be triggered when the attitude sensor detects that the fire extinguisher is in a predetermined fire-extinguishing spray attitude. The system then enters a "Position Correct?" judgment phase. If the detection result is "No", the system will perform a "delayed execution / alarm prompt" to remind the operator to adjust the attitude; if the detection result is "Yes", the system will then "activate the alarm module" and begin "activating the actuator".

[0035] Once the actuator is activated, the specific physical operation procedure is as follows: First, the control system receives the control command, and then the drive circuit is activated. Before executing the mechanical action, the system performs a safety check to ensure that all components are in normal working order.

[0036] Then, the actuator begins to operate: "Open the solenoid valve / needle valve." For dry powder fire extinguishers, a small motor is usually driven to move the needle to pierce the internal sealing aluminum membrane; for gas fire extinguishers, the solenoid valve is opened directly.

[0037] The next step is to "puncture the sealing mechanism" to ensure the extinguishing agent can flow out smoothly. Then, the action of "releasing the extinguishing agent" begins. During the release process, the system continuously "monitors the extinguishing effect".

[0038] After a certain period of release, the system enters the "Fire Extinguished?" judgment node. If the judgment result is "No", the "Continue Release" action continues until the fire is under control; if the judgment result is "Yes", the "Stop Release" command is issued, the valve is closed, and the fire extinguishing process ends.

[0039] The alarm and communication process of this invention is mainly divided into two paths: Path 1: Once the system confirms a fire, it first "receives an alarm command," followed by "activating the audible and visual alarm." Simultaneously, the "local display" module will display information such as the fire level and equipment status on the fire extinguisher's display screen or indicator light. At the same time, the "wireless communication module" begins to work, performing "remote data packaging."

[0040] The packaged data is then sent to the "network connection status" checkpoint. If the network is "normal," the data will be directly "sent to the monitoring terminal"; if the network is "abnormal," the system will store the data in a local cache and retransmit it after the network is restored, or attempt to send it periodically.

[0041] Path 2: For the remote control function, the system "receives remote control commands", then performs "command parsing", confirms the legality and content of the commands, and then executes the corresponding operations.

[0042] In addition, the system also has a scheduled maintenance function. The system will periodically send "timed heartbeat packets" and "equipment status reports" so that the back-end management personnel can keep track of the equipment's power, valve status and other health information at any time.

[0043] To meet the need for manual intervention in emergency situations, this invention sets up an independent manual triggering process. When the manual button is pressed manually, the system first performs a signal input verification to confirm the authenticity of the button signal.

[0044] Once verification is successful, the system will "bypass automatic judgment" and directly proceed to the execution or alarm branch. The operator can choose to "directly activate the actuator," and the system will immediately execute the action of "releasing the extinguishing medium"; or choose to "directly activate the alarm," and the system will issue a high-decibel alarm and "send the manual trigger record" to the "remote monitoring platform" so as to trace later who activated the fire extinguishing device and when.

[0045] To ensure effective fire suppression, the system has strict requirements regarding attitude. The system uses an "attitude sensor monitoring" module to perform "real-time angle detection" using internal gyroscopes and accelerometers.

[0046] The system has a preset optimal spray angle range, and then checks whether the angle meets the requirements. If it does not meet the requirements, the system will refuse to execute the command and issue a posture warning. However, considering the subjective initiative of human intervention in extreme emergency situations, the system introduces a manual confirmation function. The operator can force execution through specific actions.

[0047] At this point, the system enters a "force execution?" judgment. If the operator confirms that execution is necessary, the system "allows execution" and performs the mechanism action; otherwise, execution is still refused. This design, combining "automatic error prevention" and "manual confirmation," ensures both safety in daily use and full functionality availability in emergency situations.

[0048] The power module is a rechargeable battery and is equipped with an external charging interface or a solar charging panel to ensure long-term stable operation of the device. Regarding data transmission, after the "control system data acquisition" is completed, the system first establishes a "wireless module connection."

[0049] The system then assesses the "network connection status." To improve the real-time performance of data transmission, if the connection is "normal," the system will "accelerate data transmission" and report the fire as soon as possible; if the connection is "abnormal," the system will initiate "local data storage," saving large amounts of data such as collected images and temperatures in local flash memory. This data will be uploaded in batches after the network is restored, or the system will send storage status information via periodic heartbeat packets to ensure that no data is lost.
