[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an automatic warning and alarm fire extinguishing device of the present invention includes a housing 1, a smoke detector 16, an inner cover 17 and an outer cover 6. The smoke detector 16 is installed on the housing 1. The inner cover 17 is arranged outside the smoke detector 16. The open end face of the inner cover 17 is installed on the housing 1. The outer cover 6 is sleeved outside the inner cover 17. A plurality of first smoke inlets 18 are arranged in a ring structure on the inner cover 17. A plurality of second smoke inlets 7 communicating with the first smoke inlets 18 are arranged on the outer cover 6. The open end face of the outer cover is bent outward to form a flange, and the flange is movably connected to the housing 1. A limit port 11 is arranged on the bottom surface of the housing 1. A fixed rod 12 is installed at the position where the top surface of the flange faces the limit port 11. One end of the fixed rod 12 extends into the housing 1 and is installed with a push plate 13. A fire extinguishing mechanism is installed outside the housing 1;

[0023] Among them, the smoke detector is a waterproof smoke detector, which avoids damage caused by water spraying.

[0024] In this embodiment, the fire extinguishing mechanism includes a C-shaped pipe 3, a water inlet pipe 5, a water outlet pipe 8, and a plurality of fire nozzles 4. The water inlet pipe 5 and the water outlet pipe 8 are oppositely arranged outside the housing 1. The C-shaped pipe 3 is sleeved outside the housing 1 and fixedly connected to the water outlet pipe 8. The plurality of fire nozzles 4 are evenly installed on the bottom surface of the C-shaped pipe 3 in an annular structure.

[0025] In this embodiment, a water guiding shell 9 is installed inside the housing 1. A diversion channel 10 with a "C" shape is formed between the water guiding shell 9 and the housing 1. A push plate 13 is arranged inside the diversion channel 10, and a through hole 14 is provided in the middle of the push plate 13. One end of the water inlet pipe is connected to the indoor fire water pipe, so that the fire water can smoothly enter the inside of the housing and flow along the diversion channel.

[0026] In this embodiment, a connecting ring is installed on the top surface of the flanging. An annular connecting groove 15 is provided on the bottom surface of the housing 1 corresponding to the connecting ring. The connecting ring is movably arranged in the connecting groove 15. The cross sections of the connecting ring and the connecting groove 15 are both trapezoidal structures, so that the external part can only rotate along the connecting groove, avoiding detachment from the housing.

[0027] In this embodiment, both the inner cover 17 and the outer cover 6 are made of metal materials, which increases the effect of high temperature resistance, avoids being burned, and because it will be washed by water, it will not have too high a temperature to cause damage to the smoke detector.

[0028] In this embodiment, a fixing plate 2 is installed on the opening end surface of the housing 1. A plurality of fixing holes are provided on the fixing plate 2, and bolts can pass through the fixing holes to fix the device indoors or outdoors.

[0029] In this embodiment, a compression spring is installed between the limit port 11 and the fixing rod 12.

[0030] Once a fire occurs outside, the smoke generated by the fire can contact the internal smoke detector through the second smoke inlet and the first smoke inlet, so that the smoke detector can immediately detect the fire situation, causing the smoke detector to sound an alarm. Once the fire alarm controller confirms the fire, it will activate the fire extinguishing system (this is prior art, so no detailed introduction is given), and send a start signal to the fire nozzles. After receiving the start signal, the fire nozzles will quickly open the valves and spray water in a high-pressure form through the fire nozzles to form water mist or water columns to cover the fire area for fire extinguishing;

[0031] Among them, after the water flows, it can immediately pass through the through hole and push the push plate. The movement of the push plate drives the fixed rod, causing the fixed rod to move along the limit port. The movement of the fixed rod drives the flanging and the outer cover. After the outer cover moves, the second smoke inlet on the outer cover is misaligned with the first smoke inlet on the inner cover, thereby covering the internal smoke detector, avoiding direct contact between the external flame and the smoke detector. And after the fire fighting water is ejected from the fire sprinkler, part of the water can wash on the outer cover and can cool it, avoiding being burned due to high temperature, so that it can be reused later;

[0032] Among them, after the fire fighting water stops, the thrust of the water acting on the push plate will disappear. At this time, the rebound of the compression spring can reversely push the push plate, the fixed rod and the outer cover, so that the second smoke inlet on the outer cover is in contact with the first smoke inlet on the inner cover again, so as to detect the external situation again.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that is thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
