Detailed Description
The invention is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1, the safe microminiature fire extinguishing device comprises a cylinder body 1 and a cylinder cover 2 positioned at one end of the cylinder body 1, wherein a columnar fire extinguishing agent 3 is arranged in the cylinder body 1, an ignition device 4 is arranged at the end part of the columnar fire extinguishing agent 3, and a plurality of spray holes 5 are formed in the surface of the cylinder body 1.

In this embodiment, if the ignition device 4 adopts a fire-guiding rope structure (as shown in fig. 2), one end of the fire-guiding rope can be directly connected with the end of the columnar fire extinguishing agent 3, and the other end of the fire-guiding rope is arranged outside the cylinder 1, so that the fire-guiding rope can be ignited when a fire occurs outside, and the columnar fire extinguishing agent 3 can be ignited; if the electric ignition head structure is adopted, a temperature sensor and/or a smoke sensor can be arranged outside the cylinder body 1, and after the temperature sensor detects that the outside generates a high-temperature environment due to fire, a signal is generated to a microprocessor (in the embodiment, the microprocessor can select a 51 single chip microcomputer, a model number is 80C51 single chip microcomputer or an STM32 microprocessor, the model number is STM32F 103), the microprocessor controls the ignition device 4 to be started, and the columnar fire extinguishing agent 3 is directly ignited, so that the function of automatic control can be realized.
Preferably, the cylinder 1 is a hollow cylinder structure with one end closed and the other end open, the diameter of the cylinder is 5-20mm, and the height of the cylinder is 20-60mm. The cartridge 1 of this size is well suited for being placed in electrical appliances where the space inside the casing is very small, such as batteries, power strip, fixed sockets, electricity meter boxes and electricity meters within the electricity meter boxes.
Preferably, the outside of the cylinder cover 2 and the outside of the cylinder body 1 are both provided with limiting blocks 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): the ignition device 4 is started and ignites the columnar fire extinguishing agent 3 when a fire disaster occurs;
step 2): the columnar fire extinguishing agent 3 is gradually ignited from the ignition end towards the other end, and gradually releases the fire extinguishing agent;
step 3): the fire extinguishing agent is sprayed outwards from the spray hole 5 close to the ignition device 4, and the spray hole 5 blocked by the columnar fire extinguishing agent 3 is gradually opened in the spraying process;
step 4): the fire extinguishing agent is gradually sprayed outwards away from the spray holes 5 of 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 reduced ten times (the diameter of the cylinder body 1 is 10mm, the height is 41 mm) in the same proportion, and the fire extinguishing concentration of at least 2g aerosol for extinguishing 0.1 cube is required.
