[0032] 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.

[0033] Reference Figures 1 to 5This utility model provides an embodiment of an intelligent smoke-detecting fire extinguishing device, comprising a bottom cover 1. The bottom cover 1 serves as a bottom support structure, providing protection and installation space for the internal smoke detector 19, and forming an overall frame through a fixed connection with a water tank 2, ensuring the stability of each component. A water storage component is fixedly connected to the top of the bottom cover 1, including a water tank 2 fixed to the top of the bottom cover 1, which stores water required for fire extinguishing. An installation ring 3 is fixedly connected to the top of the water tank 2, with pre-set installation holes on the installation ring 3 suitable for fasteners such as expansion bolts. The ring structure ensures uniform force distribution and prevents loosening during installation. A water inlet pipe 4 is fixedly connected to the right side of the water tank 2, which adds water to the water tank 2. A sealing plug 5 is detachably connected to the top of the water inlet pipe 4, which covers the water inlet pipe 4. A rubber ring 6 is fixedly connected to the bottom of the sealing plug 5, which engages with the inner wall of the water inlet pipe 4. The rubber ring 6 uses elastic deformation to fill gaps, achieving a leak-proof and dust-proof seal, ensuring water quality cleanliness.

[0034] A slope plate 7 is fixedly connected to the bottom of the inner wall of the water tank 2. The slope plate 7 is designed with an inclination to guide the water flow to the center by gravity. A through hole 8 is opened in the center of the slope plate 7 to guide the water flow to the water pipe 9, avoid water accumulation and make full use of water resources. A water pipe 9 is fixedly connected to the bottom of the water storage component. The water pipe 9 is used to transport water in the water tank 2. The top of the water pipe 9 is fixed to the bottom of the water tank 2. Two locking blocks 10 are fixedly connected to the outside of the water pipe 9. The locking blocks 10 cooperate with the locking groove 18 to realize the connection and fixation of the water pipe 9 and the outlet pipe 16. A top box 11 is also fixedly connected to the outside of the water pipe 9. The top box 11 provides installation space for the compression pad 12 and the elastic component. The compression pad 12 is slidably connected inside the top box 11. Under the action of the elastic component, the compression pad 12 is tightly attached to the top of the outlet pipe 16 to fill the connection gap and prevent water leakage.

[0035] The top box 11 has an internal elastic component that provides continuous pressure to the compression pad 12. The elastic component includes a limiting ring 13 fixed to the top of the compression pad 12, which is used to fix the position of the compression pad 12. Multiple sliding pillars 14 are fixedly connected to the top of the limiting ring 13. The sliding pillars 14 are used to guide the compression pad 12 to move vertically and ensure the stability of the spring 15 to prevent breakage. The sliding pillars 14 are fitted with springs 15, which are in a slightly compressed state to provide continuous pressure. One end of the spring 15 is fixedly connected to one side of the inner wall of the top box 11, and the other end of the spring 15 is fixedly connected to one side of the limiting ring 13. The bottom of the water supply pipe 9 is detachably connected to a water outlet pipe 16, which is used to guide the water supplied by the water supply pipe 9 to the atomizing nozzle 17.

[0036] The top of the water outlet pipe 16 is in close contact with the bottom of the compression pad 12. A miniature water pump for drawing clean water from the water tank 2 is fixedly connected to the outside of the water outlet pipe 16. The miniature water pump provides power for the water flow and draws water from the water tank 2 to the water outlet pipe 16. The surface of the water outlet pipe 16 is provided with a textured surface for easy disassembly. The textured surface increases friction and makes it easy for staff to disassemble and maintain the atomizing nozzle 17. The bottom of the water outlet pipe 16 is fixedly connected to the atomizing nozzle 17, which is used to convert the water flow into mist particles to achieve effective fire extinguishing over a wide area. The inner wall of the water outlet pipe 16 is provided with a slot 18 that engages with the locking block 10. The slot 18 and the locking block 10 cooperate to achieve a detachable connection between the water supply pipe 9 and the water outlet pipe 16. A smoke detector 19 is installed inside the bottom cover 1. The smoke detector 19 is used to detect smoke in the environment and trigger the miniature water pump to start the fire extinguishing procedure.

[0037] Working principle: First, the device is fixedly installed by means of the mounting ring 3 on the top of the water tank 2. The preset mounting holes on the mounting ring 3 can be used to fit fasteners such as expansion bolts. The ring structure ensures uniform force and avoids loosening of the installation. The bottom cover 1 serves as the bottom load-bearing structure, which not only provides protection and installation space for the internal smoke detector 19, but also forms an overall frame through the fixed connection with the water tank 2, ensuring the stability of the position of each component.

[0038] During the water storage process, water tank 2 is filled with water through inlet pipe 4. After the sealing plug 5 is closed, the rubber ring 6 at the bottom fills the gap with elastic deformation to achieve a seal that prevents leakage and dust, ensuring the cleanliness of the water. The slope plate 7 at the bottom of the inner wall of water tank 2 is designed with an inclination to guide the water flow to the center with the help of gravity. The water then flows through the through hole 8 to the water supply pipe 9, avoiding water accumulation and making full use of water resources.

[0039] When the smoke sensor 19 inside the bottom cover 1 detects smoke, it triggers a miniature water pump to draw water through the through hole 8 and the water supply pipe 9 to the water outlet pipe 16, providing water flow power.

[0040] After prolonged use, the atomizing nozzle 17 needs to be disassembled for maintenance and cleaning. The water supply pipe 9 and the water outlet pipe 16 are detachably connected by the locking block 10 and the locking groove 18. During installation, the water outlet pipe 16 is rotated to lock the two together. During disassembly, the operation is reversed. The horizontal or oblique texture on the surface of the water outlet pipe 16 can increase the friction and facilitate disassembly and maintenance. At the same time, the compression pad 12 in the top box 11 is always in close contact with the top of the water outlet pipe 16 under the action of the elastic component. The limiting ring 13 fixes the position of the compression pad 12, and the sliding column 14 guides its vertical movement, while ensuring the stability of the spring 15 and preventing breakage. The slightly compressed spring 15 provides continuous pressure, fills the connection gap, and prevents water leakage.

[0041] Finally, the pressurized water flows into the atomizing nozzle 17, turning the water into mist particles. These particles, with their large surface area, quickly absorb heat, lower the temperature, and evenly cover the surface of the burning material to isolate oxygen, thereby achieving efficient fire extinguishing.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
