The technical scheme for realizing the patent is that the fire protection device comprises a fire extinguishing agent storage part and a fire extinguishing agent;
the fire extinguishing agent storage part is internally provided with a normal-pressure fire extinguishing agent;
the fire extinguishing agent storage part is a sealing part which is damaged or melted or softened or burnt and broken when meeting heat energy.
Preferably, the fire suppressant is readily vaporized upon heating.
Preferably, the fire extinguishing agent is a fluorinated ketone or a mixture of fluorinated ketones.
Preferably, the fire extinguishing agent storage member is made of plastic or plastic and a combination thereof.
Preferably, the fire extinguishing agent storage part is made of high molecular polymer or a combination of high molecular polymer and plastic.
Preferably, the fire extinguishing agent storage member is made of metal or a combination of metal and high molecular polymer.
Preferably, the fire extinguishing agent storage member is made of paper products.
Preferably, the fire extinguishing agent storage member is tubular or ribbon-like or spherical or other shape having a receiving space.
The utility model has the advantages that 1, the interior of the fire extinguishing agent storage part is in a normal pressure state, which is beneficial to the long-term storage of the fire extinguishing agent and can prolong the storage period of 12 to 24 months to more than 120 months (in the normal pressure state) compared with the prior (in the very pressure state); 2. the fire protection device has high safety system, and because the fire protection device does not have pressure (normal pressure state), the fire extinguishing agent storage piece can not have destructive accidents such as explosion and the like; 3. electronic control is not needed, and a detector is more reliable; 4. simple structure, low price and convenient construction. 5. Automatic detection, start and carry out point-to-point accurate fire extinguishing to the ignition source, the fire extinguishing agent quantity is few, practice thrift and environmental protection.

Detailed Description
The present invention will now be described with reference to the following preferred embodiments, which should not be construed as limiting the scope of the invention.
Example 1: as shown in fig. 1, the fire extinguishing agent storage member 1 is a tubular sealing member or a strip-shaped sealing member made of polybutylene terephthalate/PBT and/or low density polyethylene/LDPE and/or paper (similar to a packing box or a bag for containing beverages), the fire extinguishing agent storage member 1 is uniformly distributed in the equipment, when a fire breaks in an area protected by a fire protection device, the fire extinguishing agent storage member 1 starts to soften when the location close to a fire source is affected by the fire source to 98 ℃, after a fire extinguishing agent 2 (a mixture of fluorinated ketones or a mixture of fluorinated ketones and is easily gasified by heat) in the fire extinguishing agent storage member 1 is gasified by heat, pressure is generated in the fire extinguishing agent storage member 1, so that the surface of the fire extinguishing agent storage member close to the fire source breaks, the fire extinguishing agent 2 is sprayed out from the broken location under pressure, the fire extinguishing agent 2 is gasified by heat, the fire source is cooled by absorbing heat or forms a pressurized gas (when the fire extinguishing agent storage member 1 is not broken, the pressurized gas formed by the partial vaporization of the fire extinguishing agent 2 therein) to perform precise fire extinguishing with respect to the ignition source.
Example 2: as shown in figure 2, the fire extinguishing agent storage part 1 is polybutylene terephthalate/PBT and/or a low density polyethylene/LDPE spherical sealing part is adopted, when a fire breaks out in an area protected by a fire protection device, the fire extinguishing agent storage part 1 is thrown to the vicinity of a fire source, the fire extinguishing agent storage part 1 begins to soften when the position close to the fire source is affected by the fire source and reaches 220 ℃, after the fire extinguishing agent 2 in the fire extinguishing agent storage part 1 is gasified by heat, pressure is generated inside the fire extinguishing agent storage part 1, therefore, the surface of the fire extinguishing agent storage part close to the fire source is broken, the fire extinguishing agent 2 is sprayed out from the broken position under pressure, and the fire extinguishing agent 2 is sprayed or simultaneously sprayed out with pressure gas at the fire source to reduce the temperature so as to realize accurate fire extinguishing.
Example 3: as shown in figure 3, the fire extinguishing agent storage member 1 is made of metal (the fire extinguishing agent storage member 1 can be made into any shape by using metal materials, a hollow part is arranged in the shape, the fire extinguishing agent 2 is arranged in the hollow part), at least one through hole is arranged on the metal surface, the through hole is sealed by polybutylene terephthalate/PBT and/or low density polyethylene/LDPE, when in use, the sealing material of the through hole is damaged after being heated, so that the fire extinguishing agent 2 in the hollow part flows out or is sprayed out from the through hole, and the fire extinguishing agent 2 is sprayed or simultaneously pressurized gas is sprayed out at a fire source to reduce the temperature, thereby realizing accurate fire extinguishing.
Example 4: as shown in figure 4, the fire extinguishing agent storage part 1 is made of metal and is of a thin sheet or a structure with a built-in space formed by combining two or more tangible metal structures, the fire extinguishing agent 2 is placed in the built-in space of the fire extinguishing agent storage part 1, a connecting part which is easily damaged when being heated or under the action of external force is arranged at the joint, when the fire extinguishing agent storage part is used, the connecting part is damaged when being heated or under the action of external force, the fire extinguishing agent 2 flows out or is sprayed out of the built-in space, and the fire extinguishing agent 2 is sprayed or simultaneously sprayed with pressure gas to reduce the temperature at a fire source so as to realize accurate fire extinguishing.
