In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.
[0033] In order to facilitate the installation of a fire extinguishing device that can orderly start the fire extinguishing agent column 5 and make its spraying time controllable in a small space, see Figure 1-Figure 3 The utility model provides an aerosol fire extinguishing device capable of directionally igniting, comprising an upper shell 1 and a lower shell 2 which are combined to form a hollow cavity, wherein a barrier component 3, a starting component 4, and a fire extinguishing agent column 5 are arranged in the hollow cavity; the starting component 4 is arranged in the middle of the barrier component 3, and a plurality of the fire extinguishing agent columns 5 are laid flat on one side of the barrier component 3 where the starting component 4 is arranged, so that the starting component 4 is located between the barrier component 3 and the fire extinguishing agent column 5, and when the starting component 4 is ignited, the energy generated is gathered to quickly ignite the fire extinguishing agent column 5 (such as Figure 1 B and C in the figure, and then ignite the adjacent fire extinguishing agent columns 5 (such as A, D, etc.) through B and C, and then realize the orderly start of the fire extinguishing agent columns 5, and the spraying time is controllable.
[0034] In the specific implementation process, the barrier component 3 divides the hollow cavity into an aerosol generating area 6 and a coolant filling area 7 adjacent thereto; the starting component 4 and the fire extinguishing agent column 5 are located in the aerosol generating area 6, so that after the starting component 4 is ignited, the heat is quickly transferred to the fire extinguishing agent column 5 to generate an aerosol in the aerosol generating area 6, and then moves to the coolant filling area 7 to fully react with the coolant in this area, thereby isolating the flame of the fire extinguishing agent column 5 during the reaction process, and then rushes out of the coolant filling area 7 to extinguish the fire. More specifically, an aerosol overflow port 21 is provided on the side walls of the upper shell 1 and the lower shell 2, and the upper shell 1 is sleeved on the lower shell 2 so that the aerosol overflow ports 21 opened on the two are opposite to each other, and the aerosol overflow port 21 is opened on the side wall corresponding to the coolant filling area 7, and a seal adapted thereto is provided on the aerosol overflow port 21, so that the reacted aerosol breaks through the seal and overflows from the aerosol overflow port 21.
[0035] In the specific implementation process, see Figure 1-Figure 3 The barrier assembly 3 includes a partition 31 and a group of side baffles 32 tightly fixed to the side walls of the partition 31; the starting component 4 is arranged in the middle of the group of side baffles 32, so that the partition 31, the side baffles 32, and the upper shell 1 enclose a space with an opening on one side, and the opening faces the side where the fire extinguishing agent column 5 is laid, so that after the starting component 4 is ignited, its energy is quickly accumulated in the open space, and it quickly moves toward the direction where the fire extinguishing agent column 5 is laid to ignite the fire extinguishing agent column 5 adjacent to it. To facilitate the orderly starting of the plurality of fire extinguishing agent columns 5 laid out, the length of the opening is less than the total length of the fire extinguishing agent columns 5 laid out on the corresponding side. Preferably, the length of the opening is an integer multiple of the length of the fire extinguishing agent columns 5. According to the length requirement of the fire extinguishing agent columns 5 laid out in the fire extinguishing device, optionally, the length of the opening is half of the total length of the fire extinguishing agent columns 5 laid out on that side, so that the two ends of the opening are equidistant from the outermost fire extinguishing agent columns 5 laid on that side, so as to achieve orderly ignition of the fire extinguishing agent columns 5.
[0036] More specifically, in order to save space and start the fire extinguishing agent column 5 in an orderly manner, the partition 31 is arranged in parallel with a group of side walls of the lower shell 2 and has the same length, and the starting component 4 is co-centrally aligned with the group of side walls; a group of side baffles 32 is arranged in parallel with another group of side walls of the lower shell 2. Optionally, the partition 31 includes a horizontal plate 31a and a plurality of vertical plates 31b vertically fixed to the horizontal plate 31a, and the plurality of vertical plates 31b are evenly spaced on the horizontal plate 31a, so that the aerosol in the aerosol generating area 6 moves to the coolant filling area 7 through the gaps between the adjacent vertical plates 31b. The horizontal plate 31a is arranged parallel to a set of side walls of the lower shell 2 and has the same length; optionally, the width of the vertical plate 31b close to the lower shell 2 is greater than that of other vertical plates 31b, so that the aerosol first enters the coolant filling area 7 to fully react with the coolant therein, so as to isolate the flame of the fire extinguishing agent column 5 during the reaction process, and then overflows from the aerosol overflow port 21; in order to enhance the concentration of energy when the starting component 4 is ignited, the longitudinal section of the side baffle 32 is constructed in an inverted L shape to prevent the energy of the starting component 4 from overflowing to the outside of the side baffle 32. Preferably, the side baffle 31 close to the partition 31 is connected to the corresponding vertical plate 31b to form a structure with two openings, one opening facing the starting component and the other opening facing the direction of the fire extinguishing agent column 5.
[0037] In a specific embodiment, the starting component 4 is a starting medicine bag embedded with a combustion-supporting component. The combustion-supporting component is a thermal wire structure or an electric ignition head structure. In this embodiment, when the starting component 4 is a thermal wire structure, it can be automatically started when a fire occurs, and the thermal wire directly ignites the fire extinguishing agent column 5 without the need for additional fire detection devices and other external devices; when the combustion-supporting component is an electric ignition head structure, it is connected to a fire detection device (the fire detection device is a temperature sensor and / or a smoke sensor). When a fire, overheating, etc. occurs, the fire detection device detects that the external high temperature environment is generated by the fire, and sends a signal to the microprocessor, and the microprocessor controls the starting component 4 to ignite the fire extinguishing agent column 5. The fire extinguishing agent column 5 is a columnar structure formed by pressing aerosol generating agent powder.
[0038] The utility model is achieved in this way:
[0039] The starting component 4 is turned on, and the energy generated by the starting component 4 is gathered in the space enclosed by the barrier component 3, the upper shell 1, etc., and then the fire extinguishing agent column 5 (such as the fire extinguishing agent column 5) adjacent to the starting component 4 is quickly ignited. Figure 1 B and C in the aerosol generating area 6 are used to ignite the adjacent extinguishing agent columns 5 (such as A and D), thereby achieving the purpose of orderly starting the extinguishing agent columns 5 in the aerosol generating area 6 and controlling the spraying time.
[0040] The generated aerosol moves to the coolant filling area 7 to fully react with the coolant in the area, isolating the flame of the fire extinguishing agent column 5 during the reaction process, and then rushes out of the coolant filling area 7 to extinguish the fire. (See Figure 1-Figure 4 )
[0041] In the implementation scheme, preferably, the starting component 4, the barrier, and the fire extinguishing agent column 5 are all carried by the lower shell 2, and the upper shell 1 and the lower shell 2 can be fixed by bolts after being buckled.
[0042] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.
[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
