[0035] like Figure 1-5 A fire extinguishing device shown includes a shell, which is composed of a top cover 5, a bottom cover 22 and a sleeve 21. A fire extinguishing component, a pushing component and an ignition component are arranged inside the shell, and the top cover 5 is the end of the nozzle 2. A detachable rotary joint 1 is connected at the end of the nozzle 2, and the detachable structure is convenient for production and assembly. A nozzle 2 is opened on the side of the rotary joint 1, and the ignition component ignites the pushing component. The pushing component provides power to spray out the fire extinguishing component in the fire extinguishing component. The fire extinguishing component is blocked by the top of the rotary joint 1, and is sprayed out from the nozzle 2 on the side, forming a steering spray effect. In order to prevent the device from exploding due to excessive pressure during spraying, the top of the rotary joint 1 is opened, and a pressure relief diaphragm 8 is arranged at the opening.

[0036] like Figure 3-5 As shown, one of the rotary joint 1 and the shell end is provided with a rotation groove 3, and the other is provided with a block 4 engaged with the rotation groove 3. That is, if the rotary joint 1 is provided with a rotation groove 3, then the shell end is provided with a block 4; or if the rotary joint 1 is provided with a block 4, then the shell end is provided with a rotation groove 3; the rotation groove 3 and the block 4 are rotationally engaged. In one embodiment, the rotation groove 3 is provided on the top cover 5, the middle part of the top cover 5 is open, the middle part of the top cover 5 is provided with a round cover 6, and a connecting block 7 is connected between the round cover 6 and the top cover 5. If the designed nozzles 2 are two groups symmetrical about the rotary joint 1, the middle line of the two nozzles 2 is perpendicular to the direction of the connecting block 7. This design can minimize the obstruction of the connecting block 7 to the spraying of the flame-spraying component.

[0037] Specifically, the fire extinguishing assembly includes a coolant 11 and a ceramic ball 12 arranged from top to bottom, a heat-insulating silicone sleeve 13 is arranged on the side of the fire extinguishing assembly, a mesh pad 10 is arranged on the top of the fire extinguishing assembly, and a sealing pad 9 is arranged on the top of the mesh pad 10. The pushing assembly includes a coated drug column 18 located below the ceramic ball 12, and a protective sleeve 17 opened to the nozzle 2 end of the shell is arranged on the outside of the coated drug column 18, and an elastic member 19 is connected between the protective sleeve 17 and the bottom wall in the shell, and a silicone pad 20 is arranged between the elastic member 19 and the bottom wall in the shell. The elastic member 19 is used to buffer and rebound to strengthen the injection force after the drug column is ignited. The elastic member 19 is preferably a spring. The spring can also ensure that the contact surface between the spring and the bottom silicone pad 20 can be buffered at the moment of starting the fire extinguishing device, rather than applying a rigid impact force. (If a rigid impact force is formed, the silicone pad 20 is easily damaged and leaks).

[0038] The ignition assembly includes an igniter 15 located between the coated powder column 18 and the ceramic ball 12, an ignition powder 14 covering the igniter 15, and a wiring harness 16 connected to the igniter 15 from the outside of the shell. The bottom cover 22 has a wire outlet hole for passing the fire extinguishing device to start the wiring harness 16. The wire outlet hole is provided with a glue dispensing groove, and the glue dispensing groove is provided with a step. The inside is filled with epoxy resin. When the epoxy resin is air-dried, the step of the glue dispensing groove ensures that the epoxy resin will not fall off. The silicone pad 20 on the inner side of the bottom cover 22 has a flat edge for the wiring harness 16 to pass through. When the fire extinguishing device is started, the silicone pad 20 will be squeezed under the action of the internal pressure of the device so that the edge and the wiring harness 16 are tightly attached together, and at the same time, the epoxy resin achieves a sealing effect. Under the action of the step, the epoxy resin can withstand the internal pressure of the device to a large extent without falling off the device.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
