[0026] In one embodiment, as shown in Figure 1 and Figure 2 A fire extinguishing device, comprising installation box 100, water distribution box 200 and two-stage spray head assembly 300, installation box 100 is fixed on the ceiling, water distribution box 200 is arranged below installation box 100, electric telescopic rod 400 and first bellow 500 are arranged between installation box 100 and water distribution box 200, two-stage spray head assembly 300 is arranged in water distribution box 200, water distribution box 200 bottom is equipped with inductive assembly, when using, after inductive assembly senses fire, control electric telescopic rod 400 elongation drives water distribution box 200 to move down, simultaneously, two-stage spray head assembly 300 extends from water distribution box 200, then starts to spray water and extinguishes fire.

[0027] In one embodiment, as shown in Figure 3As shown, the mounting box 100 includes a first box body 101, a mounting groove 102 on the first box body 101, a mounting seat 103 on the side wall of the first box body 101, a sealing plate 104 on the top of the first box body 101, a water inlet pipe 105 in the mounting groove 102, and a solenoid valve 106 on the water inlet pipe 105. In use, the water inlet pipe 105 is connected to an external water source. When a fire is detected, the solenoid valve 106 will automatically open, allowing water to flow downward into the two-stage sprinkler assembly 300.

[0028] In one embodiment, such as Figure 4 As shown, the water distribution box 200 includes a second box body 201 and a base plate 202. The second box body 201 is located below the mounting box 100, and the base plate 202 is fixed to the bottom of the second box body 201. A water distribution groove 203 is provided in the middle of the second box body 201. Storage grooves 204 for placing two-stage nozzle assemblies 300 are evenly distributed on the outer side of the water distribution groove 203. A through hole 205 is provided between the storage groove 204 and the water distribution groove 203. A sliding groove 206 is provided at the upper end of the storage groove 204. An opening 207 is provided at one end of the sliding groove 206. In use, water flows in from the water inlet pipe, passes through the first corrugated pipe 500, enters the water distribution groove 203, and then enters each of the two-stage nozzle assemblies 300 through the through hole 205.

[0029] In one embodiment, such as Figure 5 As shown, the two-stage nozzle assembly 300 includes a primary nozzle 301 and a secondary nozzle 302. The primary nozzle 301 is located in the receiving groove 204, and the secondary nozzle 302 is connected to the lower end of the primary nozzle 301. One end of the primary nozzle 301 is connected to a second corrugated pipe 303, which is connected to a through hole 205. A spring 304 is sleeved on the outside of the second corrugated pipe 303. A traction component is provided at the top of the primary nozzle 301. In use, when the water distribution box 200 moves downward, the primary nozzle 301 and the secondary nozzle 302 will move outward along the receiving groove 204 simultaneously under the action of the traction component.

[0030] In one embodiment, such as Figure 5 As shown, the traction assembly includes a slider 305 fixed to the top of the primary nozzle 301. The slider 305 is slidably disposed in the slide groove 206. A traction rope 306 is provided on the slider 305. One end of the traction rope 306 passes through the opening 207 and is fixedly connected to the mounting box 100. In use, when the water distribution box 200 moves downward, the traction rope 306 is pulled by the mounting box 100, causing the slider 305 to move outward along the slide groove 206, thereby causing the primary nozzle 301 and the secondary nozzle 302 to move outward. When the water distribution box 200 moves upward, the primary nozzle 301 and the secondary nozzle 302 will return to their initial state under the action of the spring 304.

[0031] In one embodiment, such as Figure 2 and Figure 3As shown, the fixed end of the electric telescopic rod 400 is fixed in the mounting groove 102, and the output end of the electric telescopic rod 400 is fixedly connected to the second box 201. When no fire is detected, the electric telescopic rod 400 is in a retracted state. When the sensing component detects a fire, the electric telescopic rod 400 will automatically extend.

[0032] In one embodiment, such as Figure 2 As shown, the upper end of the first corrugated pipe 500 is connected to the water inlet pipe 105, and the lower end of the first corrugated pipe 500 is connected to the water distribution tank 203. When the electric telescopic rod 400 extends, the first corrugated pipe 500 can extend and lengthen along with the electric telescopic rod 400.

[0033] In one embodiment, such as Figure 2 As shown, the sensing components include a smoke sensor 600 and a temperature sensor 700. The smoke sensor 600 is located in the middle of the base plate 202, and the temperature sensor 700 is located on one side of the smoke sensor 600. An audible and visual alarm 800 is located on the other side of the smoke sensor 600. When the smoke sensor 600 and the temperature sensor 700 detect a fire, they will activate the device to spray water and simultaneously trigger the audible and visual alarm 800 to sound an alarm.

[0034] The above embodiment discloses a fire extinguishing device. In use, the device is fixed to the ceiling via the mounting base 103, and the water inlet pipe 105 is connected to an external water source. When the smoke sensor 600 and the temperature sensor 700 detect a fire, the electric telescopic rod 400 automatically extends, causing the water distribution box 200 to move downward. At the same time, the traction rope 306, under the tension of the mounting box 100, causes the slider 305 to move outward along the slide groove 206, thereby causing the first-stage sprinkler head 301 and the second-stage sprinkler head 302 to move outward. Simultaneously, the solenoid valve 106 automatically opens, allowing water to flow downward into the two-stage sprinkler assembly 300 and be sprayed out through the first-stage sprinkler head 301 and the second-stage sprinkler head 302 to extinguish the fire. At the same time, the audible and visual alarm 800 is triggered to sound an alarm.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
