[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-5As shown, a fire extinguishing device includes a base 12, a shell 1 with multiple vent holes 18 on the top, a heat generator 27 that generates thermal aerosols upon combustion, a cooling layer 23, and a heat-sensitive wire 10. The shell 1 is snapped onto the top of the base 12. The cooling layer 23 and the heat generator 27 are respectively disposed at the upper and lower ends inside the shell 1. The heat-sensitive wire 10 passes through the shell 1 and is fixedly connected to the heat generator 27. The shell 1 is cylindrical, and a support ring 20 with two T-shaped longitudinal sections is fixedly disposed at the upper end. A limit ring 2 is rotatably disposed at the outer end of the support ring 20. A rotating groove 3 is fixedly disposed at the top of the limit ring 2, and the rotating groove 3 is rotatably connected to the top of the shell 1. Multiple fire extinguishing holes 4 are spaced apart on the side wall of the rotating groove 3, and multiple push plates 19 are fixedly disposed spaced apart on the inner side wall. The vent holes 18 connect the shell 1 and the rotating groove 3. Both the push plates 19 and the vent holes 18 are inclined.

[0022] When an external fire causes the temperature to rise to the combustion temperature of the heat-sensitive wire 10, the heat-sensitive wire 10 begins to burn, igniting the initiating agent 27. The initiating agent 27 burns and generates a large amount of thermal aerosol. The thermal aerosol passes through the cooling layer 23 for cooling and then enters the rotating tank 3 through the exhaust port 18, pushing the push plate 19 to rotate. The push plate 19 drives the rotating tank 3 to rotate, and the fire extinguishing port 4 rotates with the rotating tank 3. The thermal aerosol is sprayed out from the rotating fire extinguishing port 4 to extinguish the fire. The limiting ring 2 rotates with the rotating tank 3 and rotates relative to the support ring 20. The material of the cooling layer 23 is magnesium carbonate particles. The initiating agent 27 and the heat-sensitive wire 10 are existing technologies and will not be described in detail here.

[0023] A heat insulation cylinder 26 is placed at the lower end of the outer shell 1. The generating agent 27 is fixedly installed inside the heat insulation cylinder 26. The heat insulation cylinder 26 is placed at the top of the base 12 and has a heat-sensitive hole. The heat-sensitive wire 10 passes through the heat-sensitive hole. A first partition 25 is placed at the top of the heat insulation cylinder 26. A heat insulation tube 24 is fixedly installed at the top of the first partition 25. A cooling layer 23 is fixedly installed inside the heat insulation tube 24. A second partition 22 is fixedly installed at the top of the heat insulation tube 24. A positioning ring 21 is fixedly installed at the upper end of the inner shell 1. The positioning ring 21 is located below the exhaust hole 18. The second partition 22 abuts against the bottom end of the positioning ring 21.

[0024] The heat insulation cylinder 26 can prevent the outer shell 1 and the base 12 from being damaged when the initiator 27 is burning, and the heat insulation tube 24 can prevent the thermal aerosol from damaging the outer shell 1, thus facilitating the reuse of the outer shell 1 and the base 12.

[0025] A sealing tube 28 is fixedly installed inside the thermal aperture, and the thermal wire 10 abuts against the inner surface of the sealing tube 28. An adhesive layer 13 is fixedly installed at the bottom end of the base 12. A protective layer 14 is fixedly installed at the bottom end of the adhesive layer 13.

[0026] The sealing tube 28 prevents external debris from entering the insulation cylinder 26 through the gap between the thermal wire 10 and the thermal hole, thus preventing damage to the generator 27 and improving the safety of the generator 27. The adhesive layer 13 facilitates the adhesion and fixation of the base 12 to external objects, and the protective layer 14 protects the adhesive layer 13, preventing it from sticking to external objects. In use, the protective layer 14 can be peeled off from the adhesive layer 13 to adhere and fix the base 12 to the external object. The protective layer 14 can be made of silicone paper.

[0027] It also includes two clamping mechanisms symmetrically arranged along the center line of the outer shell 1. Each clamping mechanism includes a mounting base 15, a clamping base 6, a clamping plate 9, and a clamping spring 7. The mounting base 15 is fixedly mounted on the outer shell 1. The clamping base 6 is slidably connected to the mounting base 15, and two rotating seats 8 are fixedly mounted at its lower end. The clamping plate 9 is rotatably connected to the two rotating seats 8. The clamping spring 7 is fixedly connected to the clamping base 6 and the clamping plate 9. An elastic layer 11 is fixedly attached to the inner side of the lower end of the clamping plate 9.

[0028] When clamping and installing, first slide both clamping seats 6 from the upper end to the lower end of the mounting seat 15. Then, the upper end of the clamping plate 9 will be pushed away from the clamping seat 6 by the clamping spring 7. The lower end of the two clamping plates 9 will clamp the external object through the elastic layer 11, thereby clamping and fixing the fire extinguishing device of this utility model onto the external object. The material of the elastic layer 11 can be rubber.

[0029] The clamping seat 6 has a sliding groove on its inner side, the mounting seat 15 is located in the sliding groove, and limit grooves 16 are opened on both sides. Limit blocks 29 are fixedly installed on both inner side walls of the sliding groove, and the limit blocks 29 are slidably installed in the limit grooves 16.

[0030] The two limiting grooves 16 and the limiting blocks 29 can prevent the clamping seat 6 from moving away from the mounting seat 15. When the clamping seat 6 slides on the mounting seat 15, the two limiting blocks 29 will move together with the clamping seat 6 and slide in the limiting grooves 16.

[0031] It also includes a positioning screw 5. The mounting base 15 has two positioning holes 17 along the height direction that are adapted to the positioning screw 5. The positioning screw 5 is threadedly connected to the clamping base 6 and extends into the positioning hole 17.

[0032] When the clamping seat 6 slides, first turn the positioning screw 5 counterclockwise to move the positioning screw 5 away from the positioning hole 17 at the upper end of the mounting seat 15. At this time, the positioning screw 5 is still on the clamping seat 6. Then slide the clamping seat 6 to the lower end of the mounting seat 15. At this time, the positioning screw 5 will be aligned with the positioning hole 17 at the lower end of the mounting seat 15. Then turn the positioning screw 5 clockwise to insert the positioning screw 5 into the positioning hole 17 at the lower end of the mounting seat 15, thus positioning the clamping seat 6.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
