[0019] 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.

[0020] Please see Figures 1-3A human-machine interactive electrical fire alarm and automatic fire extinguishing system main unit includes a protective shell 1 and a sealing cover 2. The protective shell 1 is made of a waterproof and corrosion-resistant material, specifically aluminum alloy, which provides high protection while being lightweight. For the device installed on the wall, this reduces the load at the connection points and makes the structure more stable. The protective shell 1 has a rectangular double-layer structure, consisting of an outer shell 11 and an inner shell 12, which are welded together as a single unit. The inner shell 12 is installed on the bottom surface inside the outer shell 11 and is connected to the inner surface of the outer shell 11. A rubber layer 3 is provided on the adjacent surfaces of the outer shell 11 and the inner shell 12. The same rubber layer 3 is provided on the adjacent surfaces of the outer shell 11 and the inner shell 12. A gap is left between the rubber layers 3 to form a snap-fit ​​groove 13. The sealing cover 2 includes a cover body 21 and a snap-fit ​​block 22. The snap-fit ​​block 22 is a rectangular shape with a hollow design. Its length, width and height are all adapted to the snap-fit ​​groove 13. The length and width of the cover body 21 are the same as the outer surface of the protective shell 1. When the snap-fit ​​block 22 is inserted into the snap-fit ​​groove 13, the sealing and friction of the rubber material are used to form a sealed structure between the cover body 21 and the protective shell 1. This device divides the external structure of the system host into a protective shell 1 and a sealing cover 2. Inside the protective shell 1, a snap-fit ​​groove 13 is formed by the adjacent rubber layers 3 of the outer shell 11 and the inner shell 12. The snap-fit ​​groove 13 and the sealing cover 2 are connected by a snap-fit ​​block 22. Compared with the existing technology that generally uses screws for connection, this utility model uses a snap-fit ​​structure and rubber layers 3 to achieve a seal between the protective shell 1 and the sealing cover 2. It is also more convenient to install, disassemble and inspect. It ensures that when the fire extinguishing device sprays fire extinguishing agent, it will not seep into the fire extinguishing system host, damage the circuit structure and affect the transmission of fire information. At the same time, it also makes the regular maintenance of the fire extinguishing device more convenient. Maintenance personnel do not need to spend time and effort to disassemble a large number of screws or other fasteners. This not only saves valuable time, but also reduces maintenance costs and further improves the reliability, durability and efficiency of the entire fire extinguishing system.

[0021] Please see Figures 1-3 The outer surface of the cover 21 is equipped with a display screen 23. The display screen 23 is connected to the internal detection equipment by wires. The main unit of the system is powered by an independent power supply to ensure that the main unit of the system can still work normally in the event of a fire. The outer surface of the display screen 23 is equipped with a protective layer 4 made of quartz glass. The protective layer 4 completely covers the outer surface of the display screen 23 and is fixedly connected to the cover 21. The transparent, high temperature resistant and waterproof characteristics of quartz glass protect the display screen 23 without affecting the image. A sealing strip 5 is provided at the connection between the protective layer 4 and the outer surface of the cover 21 to ensure the airtightness of the equipment.

[0022] Please see Figure 4The rear surface of the protective shell 1 is fixed with a connector 6 by screws. The connector 6 includes a slide 61 and a fixing hook 62. The fixing hook 62 is installed on the slide 61 and has a degree of freedom of movement along the slide 61. The main unit of the fire extinguishing system is installed on the wall of the area to be detected by the fixing hook 62. The connection between the main unit and the wall of the area to be detected is achieved by the fixing hook 62, which is movably connected to the slide 61. This allows for quick, stable and flexible installation without damaging the wall structure. Compared with the prior art, the connection structure occupies less space. Moreover, since the fixing hook 62 has a degree of freedom of movement on the slide 61, the main unit of the system can be flexibly adjusted and positioned in a specific area on the wall according to actual needs during the installation process.

[0023] In practical use and specific design, the protective shell 1 is equipped with the basic circuit components required for fire monitoring and signal transmission, and is connected to the display screen 23 for data transmission. The fire monitoring components are all existing technologies, so the specific connection structure and connection lines are not shown in the attached drawings of the manual. An alarm 7 is installed on the outer wall of the protective shell 1. The alarm 7 is located at the top of the protective shell 1. The alarm 7 includes an LED light assembly and a buzzer. The alarm 7 is controlled by the internal circuit system of the protective shell 1. The main unit of the system achieves data connection with the user's communication terminal through wireless communication modules such as LoRa and 4G. When the monitored ambient temperature or smoke detector is abnormal, the fire extinguishing main unit immediately activates the alarm 7 and sends an SMS alarm to a pre-set mobile phone through the wireless communication module.
