Description

Technical Field

[0001] The utility model relates to the technical field of fire safety, in particular to a multifunctional vehicle fire extinguisher. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemical substances are placed inside the fire extinguisher for extinguishing fires. Fire extinguishers are one of the common fire-fighting equipment and are stored in public places or places where fires may occur. The components filled in different types of fire extinguishers are different and are designed specifically for different fire causes. When using, attention must be paid to avoid counter-effects and causing danger.

[0003] After retrieval, the Chinese patent with the publication number CN206910623U discloses a special vehicle-mounted fire extinguisher.

[0004] The above technical solution includes a fire extinguisher body using dry powder agents and a spray gun assembly installed on the fire extinguisher body and capable of being inserted into the gap of the engine hood of the vehicle engine compartment for spraying and extinguishing fires; the spray gun assembly includes a flexible tube, a non-metallic handle, a metal spray gun rod and a metal flared spray gun. One end of the flexible tube is fixedly connected to the fire extinguisher body, and the other end of the flexible tube is fixedly installed and connected to one end of the non-metallic handle. The metal spray gun rod extends into the non-metallic handle and is fixedly installed and communicated with the flexible tube; the metal flared spray gun is installed at the end of the metal spray gun rod for inserting into the gap of the engine hood of the vehicle engine compartment for spraying and extinguishing fires. The utility model can effectively control the fire inside the vehicle engine compartment in the shortest time and effectively improve the fire extinguishing performance.

[0005] However, in the above solution, the fire extinguisher is usually placed in the vehicle. When the vehicle catches fire automatically when there is no one in the vehicle, the fire extinguisher cannot extinguish the fire automatically and cannot play the role of extinguishing the fire. Safety hammers are usually not installed in household vehicles. When the vehicle is in danger and needs to break the window for self-rescue or rescue, there is often no effective tool, missing the best opportunity for self-rescue or rescue.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, in combination with the drawings and specific embodiments, the invention will be further described:

[0024] Embodiment 1

[0025] Please refer to Figure 1Description of Embodiment 1, including a fire extinguisher 10, characterized in that: a nozzle 11 is provided at the upper end of the fire extinguisher 10, and a self-activation component 20 is connected to one side of the fire extinguisher 10. The self-activation component 20 includes a gas storage tank 23 for storing fire extinguishing materials such as solid carbon dioxide fillers. Both ends of the gas storage tank 23 are connected to an air outlet valve 24, and solid carbon dioxide is ejected from the air outlet valve 24. A thermal plug 25 is blocked inside the air outlet valve 24 to block the air outlet valve 24. One side of the gas storage tank 23 is connected to a connection valve 22, and one side of the connection valve 22 is connected to a connecting pipe 21. The connecting pipe 21 is connected to the fire extinguisher 10. The solid carbon dioxide filler stored in the fire extinguisher 10 enters the connection valve 22 through the connecting pipe 21 and then enters the gas storage tank 23 from the connection valve 22. The outer shell of the thermal plug 25 is made of thermal glass material, and a glycerol-based liquid is sealed inside the thermal plug 25. The glycerol-based liquid uses a glycerol-based liquid material with a trigger temperature of 68°. When the glycerol-based liquid reaches the trigger temperature, the outer shell can be burst open. One side of the gas storage tank 23 is fixedly connected to a support block 26, and one end inside the support block 26 is also fixedly connected to the fire extinguisher 10. The setting of the support block 26 is used to support the gas storage tank 23;

[0026] In this embodiment, the fire extinguisher 10 is connected to the connecting pipe 21, the connecting pipe 21 is connected to the connection valve 22, and the connection valve 22 is connected to the gas storage tank 23. When a vehicle catches fire spontaneously, the temperature inside the vehicle rises sharply. When the temperature reaches the trigger temperature of the glycerol-based liquid, the glycerol-based liquid expands rapidly, causing the thermal plug 25 to burst, opening the blocked air outlet valve 24. The solid carbon dioxide filler is ejected from the air outlet valve 24 to extinguish the fire inside the vehicle. It has the effects of strong stability and automatic fire extinguishing, and can automatically extinguish the vehicle fire.

[0027] Embodiment 2

[0028] Please refer to Figure 2 Description of Embodiment 2, including a window-breaking component 30 fixedly connected to the outside of the fire extinguisher 10. The window-breaking component 30 includes at least two threaded blocks 31 fixedly connected to the outside of the fire extinguisher 10. An external thread of the threaded block 31 is threadedly connected to a threaded ring 32. The threaded ring 32 is threadedly connected to the threaded block 31, so that the top cone 36 can extend or retract, and the threaded connection has self-locking property to prevent the top cone 36 from retracting into the bottom groove 12 during window breaking. The lower end of the threaded ring 32 is rotatably connected to a connecting ring 33, and the lower end of the connecting ring 33 is fixedly connected to an N-shaped connecting rod 34. The threaded ring 32 drives the connecting ring 33 to move downward. The downward movement of the connecting ring 33 drives the connecting rod 34 to move downward. One end of the connecting rod 34 is fixedly connected to a top plate 35. The top plate 35 is arranged in a bottom groove 12 opened inside the fire extinguisher 10. One side of the top plate 35 is fixedly connected to a top cone 36. The downward movement of the connecting rod 34 extends the top plate 35 out of the bottom groove 12. The movement of the top plate 35 drives the top cone 36 to extend out of the bottom groove 12. The top cone 36 is similar to a safety hammer in terms of material structure;

[0029] In this embodiment, by rotating the threaded ring 32 to rotate on the threaded block 31, the threaded ring 32 is moved downward. The threaded ring 32 drives the connecting ring 33 to move downward. The downward movement of the connecting ring 33 drives the connecting rod 34 to move downward. The downward movement of the connecting rod 34 extends the top plate 35 out of the bottom groove 12. The movement of the top plate 35 drives the top cone 36 to extend out of the bottom groove 12. The user can use the top cone 36 to break the window of the vehicle, enriching the functions of the device, avoiding tragedies caused by the lack of tools, providing the possibility of rescue for the user, and effectively improving the rescue efficiency when the vehicle is in danger.
