The control device 40 is used to control the fire extinguishing agent sprayed from the nozzle 30 according to the temperature detected by the detection member 20 .

[0037] The fire extinguishing device disclosed in the utility model includes a shell assembly 10, a fire extinguishing agent storage box, a detection member 20, a nozzle 30, and a control device 40. Among them, the shell assembly 10 is provided with a fire extinguishing agent cavity 11 and an installation cavity 12; the fire extinguishing agent storage box is arranged in the fire extinguishing agent cavity 11, and the control device 40 is arranged in the installation cavity 12, and the fire extinguishing agent storage box is used to load the fire extinguishing agent.

It should be noted here that the fire extinguishing device can be used in a variety of scenarios, and can be used in electrical cabinets, data centers, new energy vehicles, kitchens and other scenarios. Among them, the control device 40 is installed in the installation cavity 12 in the housing assembly 10, and the installation cavity 12 is arranged near the top of the housing assembly 10, so that the control device 40 can be easily disassembled and installed, which is conducive to maintenance. Installed in the housing assembly 10 to prevent external environmental factors such as dust, moisture, impact or accidental touch from damaging the circuit, thereby extending the service life and reducing the failure rate. For the fire extinguishing device, such a design can also ensure that the control device 40 is protected from the high temperature of the fire extinguishing agent or the fire scene. The integrated control device 40 in the housing is conducive to direct and efficient connection and communication with other components of the fire extinguishing device (such as detectors, actuators, gas cylinders, etc.), ensuring that the system responds quickly and the control is accurate. This helps to improve the overall coordination and automation of the fire extinguishing system. The housing assembly 10 encapsulates the control device 40 and can also increase the safety of the system, preventing unauthorized personnel from contacting and modifying the circuit settings, which is crucial to ensuring fire safety. In addition, under certain environments, such as extreme temperatures or corrosive environments, the housing assembly 10 can be designed to have a specific protection level (such as IP level) to protect the circuit board from the harsh environment and ensure stable operation of the system. Although the control device 40 is installed inside, the position near the top is relatively convenient for technicians to perform maintenance and repairs, especially in emergency situations that require quick response, so that the control device can be accessed relatively quickly. In addition, the arrangement of the control device 40 near the top of the shell assembly 10 is conducive to the natural heat dissipation of hot air rising, especially when the shell assembly 10 is designed with a corresponding heat dissipation structure, the cooling efficiency can be improved and the risk of overheating can be reduced. Furthermore, in the event of an emergency such as a fire, the control device 40 located at the top may be less directly exposed to the fire source or heat radiation, thereby improving the survivability of the system under extreme conditions and ensuring the reliability of the fire extinguishing function. It is understandable that the nozzle 30 is detachably mounted on the shell assembly 10. It can also be fixedly connected and mounted on the shell assembly 10.The detection part 20 is connected to the control device 40. The detection part 20 may include a temperature sensor, an infrared sensor, a smoke sensor and an alarm, and is used to sense fire alarm information. The temperature sensor can be used to sense the temperature of the surrounding area. If the surrounding temperature exceeds the preset value, the temperature sensor sends a fire extinguishing signal to the control device 40. The infrared sensor is used to sense the surrounding heat. When the surrounding heat is too high, the surrounding objects may reach the spontaneous combustion point. If it is not controlled, spontaneous combustion will inevitably occur. After detection by the infrared sensor, a fire extinguishing signal is sent to the control device 40 so that the fire extinguishing device releases a fire extinguishing agent to reduce the heat. The smoke sensor is used to sense whether there is smoke in the surrounding area. When the fire source is generated and does not reach the preset value of the temperature sensor, the smoke sensor also sends a fire extinguishing signal to the control device 40 after sensing it, so as to curb the spread of the fire in time; the alarm is automatically started when the temperature sensor, infrared sensor and smoke sensor send a fire extinguishing signal, reminding and warning people that a fire source has been generated and needs to be controlled in time. It can be understood that the control device 40 includes a circuit board, and the circuit board is connected to the detection part 20 respectively. It is understandable that when the detection element 20 senses the presence of fire alarm information in the surrounding area, the detection element 20 will send a fire alarm signal to the circuit board. After the circuit board receives the fire alarm information sent by the detection element 20, it controls the fire extinguishing agent in the fire extinguishing agent storage box to be output from the nozzle and act on the fire source to achieve automatic fire extinguishing. It is understandable that the circuit board is provided with a connection hole and a wireless communication module, and the external device can be connected to the circuit board through the wireless communication module, thereby controlling the working state of the control device 40.
