In addition, due to the low height of the hot aerosol fire extinguishing device, the coverage area of the hot aerosol fire extinguishing device is small, which limits the use of the hot aerosol fire extinguishing device.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] Example 1
[0026] The embodiment of the utility model provides a hand-thrown hot aerosol fire extinguishing device.
[0027] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a fire extinguisher body 1, the fire extinguisher body 1 has a built-in hot aerosol agent 3, the hot aerosol agent 3 is usually a mixture of multiple ingredients such as an oxidant, a reducing agent, and a binder. Under specific conditions, such as when encountering a fire source or high temperature, the agent will rapidly undergo a chemical reaction to produce a large amount of fire extinguishing aerosol. The fire extinguishing components in the aerosol can combine with free radicals in the combustion reaction, interrupt the combustion chain reaction, and thus suppress the continued burning of the flame. In the process of release, the aerosol will absorb a large amount of heat, reduce the temperature of the burning object, and make it below the ignition point, thereby achieving the purpose of extinguishing the fire. Moreover, the aerosol can cover the surface of the burning object to form a dense covering layer, preventing oxygen from contacting the burning object, so that the combustion stops due to lack of oxygen. A placement groove 2 is provided in the middle of the agent fire extinguisher body 1, and a hot aerosol agent 3 is provided on the inner wall of the placement groove 2. A counterweight block 4 is fixed at the lower end of the fire extinguisher body 1. A plurality of nozzles 5 are provided in the middle of the fire extinguisher body 1, and a film 6 is provided in the middle of the plurality of nozzles 5.
[0028] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth noting that the upper end of the counterweight block 4 is fixed to the bottom of the fire extinguisher body 1, the vertical section of the counterweight block 4 is elliptical, several ejection ports 5 pass through the middle of the placement groove 2, and the thickness of several films 6 becomes thinner in sequence.
[0029] When the utility model is in use, the fire extinguisher body 1 is thrown into the fire area by manpower. Due to the influence of the counterweight 4 fixed at the bottom of the fire extinguisher body 1, the counterweight 4 is affected by gravity and drives the fire extinguisher body 1 to make a parabolic motion with the counterweight 4 always at the bottom, so that the counterweight 4 is the first to contact the fire area. Since the counterweight 4 is elliptical, its center of gravity is low, and it will reset to a vertical state when it tilts. In combination with the temperature during the fire, the hot aerosol agent 3 placed in the middle of the fire extinguisher body 1 is heated. This agent is usually composed of multiple components such as an oxidant, a reducing agent, and a binder. The mixture, under certain conditions, such as encountering a fire source or high temperature, the agent will quickly undergo a chemical reaction to produce a large amount of fire extinguishing aerosol. Under the obstruction of several successively thinner films 6 arranged in the middle of the nozzle 5, the fire extinguishing aerosol is ejected from the nozzle 5 in sequence. The fire extinguishing aerosol ejected in sequence has a certain impact force, and the impact force drives the fire extinguisher body 1 and the counterweight block 4 to rotate and eject the fire extinguishing aerosol, completing the effect of rotary injection, maximizing the role of the hot aerosol fire extinguishing device, avoiding the waste of hot aerosol, and thus achieving the effect of improving the use effect of the hot aerosol fire extinguishing device.
[0030] Example 2
[0031] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , based on the first embodiment, a jump-type fire extinguishing function is added;
[0032] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It is worth mentioning that a slide groove 7 is provided at the lower end of the placement slot 2, and a connecting structure is provided on the inner wall of the slide groove 7. The connecting structure includes a sliding plate 8, and fixed frames 9 are fixed on both sides of the lower end of the sliding plate 8. A through groove 10 is provided on the lower side of the two fixed frames 9. A driving rod 11 is fixed in the middle of the two through grooves 10. The outer surfaces of the two driving rods 11 are slidably connected to the limiting frames 12. The middle parts of the two limiting frames 12 are provided with inclined grooves 13. Stabilizing frames 14 are provided on the adjacent sides of the two limiting frames 12. Limiting grooves 15 are provided on both sides of the stabilizing frame 14, and springs 16 are fixed on both sides of the stabilizing frame 14.
[0033] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The outer surfaces of the two limiting frames 12 are slidably connected to the inner walls of the two through grooves 10. The outer surfaces of the two driving rods 11 are slidably connected to the inner walls of the two inclined grooves 13. The two inclined grooves 13 are opposite to each other. The outer surfaces of the two limiting frames 12 are in contact with the inner walls of the two limiting grooves 15. The outer surfaces of the two stabilizing frames 14 are slidably connected to the inner walls of the two sides of the slide 7. The upper ends of the two springs 16 are fixed to the two sides of the lower end of the slide 8, and the lower ends of the two springs 16 are fixed to the two sides of the upper end of the stabilizing frame 14.
[0034] When the utility model is in use, the fire extinguisher body 1 is put into the fire area by manpower, so that the counterweight block 4 drives the fire extinguisher body 1 to finally stand in a vertical state in the fire source area, and the heat of the fire source can heat-initiate the hot aerosol agent 3 to react. After the reaction, the amount of the hot aerosol agent 3 is reduced, and the extrusion force of the reduced hot aerosol agent 3 on the sliding plate 8 disappears. After the extrusion force disappears, the sliding plate 8 moves upward under the pressure of the compressed spring 16, and the upward sliding plate 8 drives the fixed frames 9 fixed on both sides to move upward. The two upward fixed frames 9 drive the two limit switches 13 through the two driving rods 11 and the two inclined slots 13. The frames 12 move away from each other under the stability of the fire extinguisher body 1, and the two limit frames 12 that move away from each other slide out from the limit grooves 15 opened on both sides of the two stabilizing frames 14. At this time, the stabilizing frames 14 lack the limit of the limit frames 12, so that the compressed springs 16 are released instantly to drive the stabilizing frames 14 to move downward. The downward moving stabilizing frames 14 contact the support surface of the fire area, and with the continuous release of the elastic force of the springs 16, the fire extinguisher body 1 is bounced up, completing the effect of jumping fire extinguishing, so as to expand the scope of fire extinguishing and avoid the existence of dead corners of fire extinguishing, thereby achieving the effect of improving the practicality of the hot aerosol fire extinguishing device.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
