Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1, a safe micro-miniature fire extinguishing apparatus comprises a cylinder 1 and a cylinder cover 2 located at one end of the cylinder 1, wherein a columnar fire extinguishing agent 3 is arranged in the cylinder 1, an ignition device 4 is arranged at the end of the columnar fire extinguishing agent 3, and a plurality of spray holes 5 are formed in the surface of the cylinder 1. The ignition device 4 may be disposed at one end or both ends of the columnar fire extinguishing agent 3, and the ignition device 4 is disposed only at one end of the columnar fire extinguishing agent 3 in this embodiment.
Preferably, the plurality of spray holes are uniformly distributed on the surface of the cylinder 1.
Preferably, a plurality of spray holes are distributed on one side surface of the cylinder 1.
Preferably, a plurality of spray holes are distributed in a straight line on one side surface of the cylinder 1, and the columnar fire extinguishing agent 3 in the cylinder 1 blocks the spray holes 5.
In this embodiment, the surface of the cylinder 1 is provided with a plurality of spray holes 5, and the spray holes 5 can be uniformly distributed on the surface of the cylinder 1, so that a three-dimensional fire extinguishing process can be realized, but because the volume of the fire extinguishing agent is small, the fire extinguishing effect under a three-dimensional structure is not good; in the embodiment, the spray holes 5 can be arranged on only one side surface of the cylinder 1, and the plurality of spray holes 5 are arranged on one side surface of the cylinder 1, so that the fire extinguishing area is relatively reduced, and the fire extinguishing effect is increased under the condition that the fire extinguishing dosage is the same; in this embodiment, the spray holes 5 may also be arranged on a straight line on one side of the cylinder 1 (as shown in fig. 3 and 4), so that the fire extinguishing area can be further reduced, and the fire extinguishing effect can be further increased under the condition of the same fire extinguishing amount.
More preferably, the plurality of injection holes 5 are linearly distributed from one end close to the ignition device 4 to one end far away from the ignition device 4, and the diameters of the injection holes are gradually reduced (as shown in fig. 3). After the design, the diameter of the spray hole 5 is larger as the distance from the ignition device 4 is closer, and the diameter from the end close to the ignition device 4 to the spray hole 5 far away from the ignition device 4 is smaller and smaller, so that the advantage of the arrangement is that when the ignition device 4 ignites, because the combustion space in the cylinder body 1 is smaller, the pressure in the cylinder body 1 after the columnar fire extinguishing agent 3 is close to the surface layer of the ignition device 4 and is combusted and gasified is increased suddenly, if the caliber of the spray hole 5 is smaller, the risk of explosion is faced, therefore, the diameter of the spray hole 5 is larger as the distance from the ignition device 4 is closer, and after the columnar fire extinguishing agent 3 is gradually ignited, the combustion space in the cylinder body 1 is larger, and at the moment, if the caliber of the spray hole 5 is too.

Preferably, the ignition device 4 is a fuse structure or an electric ignition head structure, and the columnar fire extinguishing agent 3 is an aerosol fire extinguishing agent. In this embodiment, if the ignition device 4 is in a fuse structure (as shown in fig. 2), one end of the fuse can be directly connected to the end of the columnar fire extinguishing agent 3, and the other end of the fuse is arranged outside the cylinder 1, so that when a fire occurs outside, the fuse is ignited to ignite the columnar fire extinguishing agent 3; if adopt the electric ignition head structure, then can set up temperature sensor and/or smoke transducer in barrel 1 outside, after it detected the outside and produces high temperature environment because of the conflagration, take place the signal and give microprocessor (microprocessor can select for use 51 singlechips in this embodiment, and the model is 80C51 singlechip, or selects for use STM32 microprocessor, and the model is STM32F 103), microprocessor control ignition 4 opens, directly ignites column fire extinguishing agent 3, can realize automatic control's function like this.
Preferably, the cylinder 1 is a hollow cylinder structure with one closed end and the other open end, the diameter of the cylinder is 5-20mm, and the height of the cylinder is 20-60 mm. The cylinder 1 with such a size is suitable for being placed in electric appliances with a very narrow space in the housing, such as a battery pack, a socket, a fixed socket, an electric meter box and an electric meter in the electric meter box.
Preferably, the outer side of the cylinder cover 2 and the outer side of the cylinder body 1 are both provided with a limiting block 6. The limiting block 6 is beneficial to placing or installing the whole fire extinguishing device inside the shell.
In addition, the working steps of this embodiment are as follows:
step 1): when a fire breaks out, the ignition device 4 is started and ignites the columnar fire extinguishing agent 3;
step 2): the columnar fire extinguishing agent 3 is gradually ignited from the ignition end to the other end, and gradually releases the fire extinguishing agent;
step 3): the fire extinguishing agent is firstly sprayed out from the spray holes 5 close to the ignition device 4, and the spray holes 5 blocked by the columnar fire extinguishing agent 3 are gradually opened in the spraying process;
step 4): the fire extinguishing agent is gradually sprayed out to the spray holes 5 far away from the ignition device 4, and the fire extinguishing agent is released to the corresponding fire extinguishing area to participate in the fire extinguishing process.
In the prior art, the fire extinguishing concentration of the aerosol can be 20g per 1 cube, the fire extinguishing device of the embodiment is proportionally reduced by ten times (the diameter of the cylinder body 1 is 10mm, the height is 41 mm), and the fire extinguishing concentration of 0.1 cube for extinguishing 2g of aerosol is at least reached, because the volume of the fire extinguishing space is reduced, the smaller the volume of the fire extinguishing space is in the actual application process, the better the tightness of the space is, the better the fire extinguishing effect of full flooding of the aerosol is realized, and the fire extinguishing concentration is more than 2g per 0.1 cube in the actual application process.
The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
