Technical Field

[0001] The utility model relates to the technical field of aerosol fire extinguishing, in particular to an air-open aerosol fire extinguishing device. Background Art

[0002] Aerosol fire extinguisher is a new type of fire extinguishing device that uses the characteristics of aerosol to achieve the purpose of fire extinguishing. Aerosol is a mixture of solid or liquid particles suspended in a gas. The size of its particles is usually between 1-50 microns. Aerosol fire extinguisher suppresses fire by releasing aerosol. Its principles mainly include physical fire extinguishing, chemical fire extinguishing and heat absorption. Existing electrical boxes are often not designed with automatic sensing fire extinguishing equipment in mind. Traditional fire extinguishing equipment is large in size and not convenient for integration into electrical boxes with limited space. Even if some electrical boxes are installed with fire extinguishing equipment, these devices are often inconsistent with other components inside the electrical box in shape and color, and appear to be rather abrupt. This not only affects the aesthetics of the interior of the electrical box, but may also cause certain inconveniences to the circuit layout and maintenance work inside the electrical box.

[0003] Therefore, the utility model proposes an air-open type aerosol fire extinguishing device. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See Figures 1 to 8 As shown, the air-open aerosol fire extinguishing device provided by the present invention includes a left shell 1, a right shell 2, and a fixing pin 3. The left shell 1 and the right shell 2 have the same external profile. The inner wall of the left shell 1 is engaged with the inner wall of the right shell 2. The fixing pin 3 is movably engaged with the bottom ends of the back surfaces of the opposite sides of the left shell 1 and the right shell 2. The inner walls of the left shell 1 and the right shell 2 are fixedly connected to the filling bins 4, and the sides of the two sets of filling bins 4 are aligned.

[0028] The bottom ends of the left shell 1 and the right shell 2 are provided with a plurality of notches, and the bottom end of the filling bin 4 is provided with two groups of vent holes and sensing holes, and the notches are communicated with the vent holes and the sensing holes.

[0029] A trigger device 14 is provided on one side of the filling bin 4 near the sensing hole. The bottom end of the trigger device 14 is electrically connected to the sensing device 13. The bottom end of the sensing device 13 extends to the outside of the filling bin 4. The top of the trigger device 14 is electrically connected to one end of the connecting wire 9. The other end of the connecting wire 9 is electrically connected to the trigger block 8. The outer wall of the trigger block 8 is fixedly connected to the soft diaphragm 7. The upper and lower ends of the soft diaphragm 7 are fixedly connected to the two sides of the inner wall of the filling bin 4.

[0030] A propellant 5 is provided on one side of the soft diaphragm 7 , and an aerosol constituent 6 is provided on the other side of the soft diaphragm 7 . The outer walls of the propellant 5 and the aerosol constituent 6 are both in contact with the inner wall of the filling chamber 4 .

[0031] After the left shell 1 and the right shell 2 are combined and assembled, the appearance is similar to that of the air switch, and the same installation method is provided to fix the plug 3, which is convenient for installation and also beautiful, and easy for users to accept and use. When a disaster occurs, the sensing device 13 set on the outside will transmit the wire signal to the trigger device 14 after sensing. At this time, the trigger device 14 triggers the trigger block 8 by connecting the wire 9, so that the propellant 5 on both sides reacts synchronously with the aerosol component 6. The triggered aerosol component 6 starts to react chemically when it comes into contact with the air, and a large amount of fire extinguishing aerosol and other fire extinguishing components are quickly generated. At the same time, the triggered propellant 5 is quickly released to push the aerosol component 6 to erupt quickly, achieving a rapid response effect, quickly responding in the early stage of the fire, suppressing the fire, and protecting people's lives and property.

[0032] Example 2

[0033] Based on Example 1, please refer to Figures 5 to 8 As shown, the fixing pin 3 is U-shaped with raised ends and a recessed middle section, and a snap ring groove 12 is provided inside the fixing pin 3. The snap ring groove 12 is provided at the bottom ends of the left shell 1 and the right shell 2. The interior of the fixing pin 3 is fixedly connected to a limit pin 11. The limit pin 11 has a wedge-shaped structure, and the outer side of the top end of the limit pin 11 is a sloped surface.

[0034] When the left shell 1 and the right shell 2 are installed, the top groove on the back is fitted with the top raised portion of the external fixing member 10 , and the bottom raised portion of the external fixing member 10 is fitted with the top of the limiting latch 11 .

[0035] When installation is required, first fit the back of the left and right shells 1 and 2 to the surface of the external fixing member 10, and insert the upper edge of the external fixing member 10 into the groove at the upper end of the left and right shells 1 and 2. At this time, the snap ring groove 12 pulls the fixing pin 3 downward, so that the two protruding ends of the fixing pin 3 are squeezed inward by the protruding parts of the left and right shells 1 and 2 on both sides, and can move downward, so that the edge of the external fixing member 10 fits with the back of the left and right shells 1 and 2, and the pulling force on the fixing pin 3 is cancelled. The fixed pin 3 has a certain elasticity, pushing the limit pin 11 to move upward and reset, thereby clamping and fixing the lower edge of the external fixing part 10. At this time, the left shell 1 and the right shell 2 can slide on the surface of the external fixing part 10 like the air switch, and flexibly adjust the installation position. Conversely, when disassembly is required, a downward pulling force is applied to the snap ring groove 12 to cancel the limit of the top of the limit pin 11 on the external fixing part 10, and the aerosol fire extinguisher can be quickly removed. The installation is simple and can be quickly installed and disassembled by electricians.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
