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

[0026] Embodiment 1:

[0027] A fire extinguishing capsule particle comprises a capsule body 1 and a capsule cap 2, wherein the capsule body 1 is provided with an edge seal I3 at the outer edge of the joint with the capsule cap, and the capsule cap 2 is provided with an edge seal II4 at the outer edge of the joint with the capsule body; after the edge seal I and the edge seal II are fitted together, the capsule body 1 and the capsule cap 2 are sealed and combined to form a fire extinguishing material cavity, and the fire extinguishing material cavity is filled with liquid fire extinguishing material, and the liquid fire extinguishing material comprises a porous support and a liquid fire extinguishing agent, and the porous support is organic foam, organic foam, sponge, foam rubber, porous ceramic, porous carbon, fiber cotton, fiber felt, fiber paper, fiber ball or cotton; and the filling state of the porous support is block, sheet, spherical or granular.

[0028] The liquid fire extinguishing agent is perfluorohexanone fire extinguishing agent, enhanced water fire extinguishing agent, antifreeze water fire extinguishing agent or halogenated hydrocarbon fire extinguishing agent.

[0029] The liquid fire extinguishing agent evaporates after reaching a certain temperature, and the liquid fire extinguishing agent is adsorbed in the porous support, and the filling amount of the liquid fire extinguishing material is more than half of the volume of the fire extinguishing material cavity. Since the fire extinguishing material cavity is filled with liquid fire extinguishing agent, the capsule body and the capsule cap are made of sealing materials to ensure that there is no leakage.

[0030] The materials of the capsule body and the capsule cap can be the same or different, that is, the capsule body can be a PET capsule body, a PEN capsule body, a PI capsule body, a PC capsule body, a PP capsule body, a PU capsule body, a PS capsule body, a PVC capsule body, a copper capsule body, an iron capsule body, an Al capsule body, a steel capsule body or a ceramic capsule body.

[0031] The capsule cap can also be a PET capsule cap, a PEN capsule cap, a PI capsule cap, a PC capsule cap, a PP capsule cap, a PU capsule cap, a PS capsule cap, a PVC capsule cap, a copper capsule cap, an iron capsule cap, an Al capsule cap, a steel capsule cap or a ceramic capsule cap.

[0032] The capsule body and the capsule cap may be of the same or different shapes, as long as they can seal to form a fire extinguishing material cavity. The seal may be an adhesive seal, a welding seal, or a snap-on package, as long as the capsule body and the capsule cap can be sealed and combined.

[0033] In this embodiment, the capsule cap and the capsule body are shown as an example with the same shape. Figure 1 and 2 As shown, the capsule cap and the capsule body are combined by edge sealing to form a spherical capsule 1, and can also form a spherical capsule 2, such as Figure 7 As shown; it is also possible to form an ellipsoidal capsule, such as Figure 3 and 4 As shown, ellipsoidal capsule 2 can also be formed, such as Figure 5 and 6 shown.

[0034] When the liquid fire extinguishing agent is heated to a certain temperature, the flame-retardant gas will evaporate. The flame-retardant gas will break through the capsule shell, quickly spread and dilute the oxygen in the flame, thereby reducing the oxygen concentration in the flame and achieving the purpose of extinguishing the fire.

[0035] Embodiment 2:

[0036] A fire extinguishing capsule particle comprises a capsule body 1 and a capsule cap 2, wherein the capsule body 1 is provided with a sealing edge I3 at the outer edge of the joint with the capsule cap, and the capsule cap 2 is provided with a sealing edge II4 at the outer edge of the joint with the capsule body; the sealing edge I and the sealing edge II are bonded and sealed to seal the capsule body 1 and the capsule cap 2 to form a fire extinguishing material cavity, the fire extinguishing material cavity is filled with solid fire extinguishing particles that can sublime or decompose flame-retardant gas when a certain temperature is reached, and the filling amount of the solid fire extinguishing particles is more than half of the volume of the fire extinguishing material cavity.

[0037] The solid fire extinguishing particles are sodium bicarbonate fire extinguishing particles, sodium bicarbonate fire extinguishing particles, ammonium carbonate fire extinguishing particles or ammonium salt of phosphoric acid fire extinguishing particles.

[0038] The edge sealing structure is easier to fit and the sealing can be an adhesive seal or a welding seal, or a snap-on seal, as long as the capsule body and the capsule cap can be sealed and combined.

[0039] Because the fire extinguishing material cavity is filled with solid particles, the capsule body and the capsule cap can be a sealing material, a fixing material or a porous breathable material.

[0040] When the capsule body is a capsule body made of sealing material or fixing material, and the capsule cap is a capsule cap made of sealing material or fixing material, the materials of the two may be the same or different. Specifically, the capsule body may be a PET capsule body, a PEN capsule body, a PI capsule body, a PC capsule body, a PP capsule body, a PU capsule body, a PS capsule body, a PVC capsule body, a copper capsule body, an iron capsule body, an Al capsule body, a steel capsule body or a ceramic capsule body; the capsule cap may be a PET capsule cap, a PEN capsule cap, a PI capsule cap, a PC capsule cap, a PP capsule cap, a PU capsule cap, a PS capsule cap, a PVC capsule cap, a copper capsule cap, an iron capsule cap, an Al capsule cap, a steel capsule cap or a ceramic capsule cap.

[0041] When the capsule body is made of a porous air-permeable material, and the capsule cap is made of a porous air-permeable material, the capsule body and the capsule cap are locked and sealed by edge sealing I and edge sealing II, and the bearing pressure of the locking seal is not greater than 2MPa.

[0042] In this embodiment, the capsule cap and the capsule body are shown as an example with the same shape. Figure 1 and 2 As shown, the capsule cap and the capsule body are combined by edge sealing to form a spherical capsule 1, and can also form a spherical capsule 2, such as Figure 7 As shown; it is also possible to form an ellipsoidal capsule, such as Figure 3 and 4 As shown, ellipsoidal capsule 2 can also be formed, such as Figure 5 and 6 shown.

[0043] Solid fire extinguishing particles are solid particles at room temperature. When heated to a certain temperature, they will sublime or decompose to produce flame-retardant gas. The flame-retardant gas will break through the capsule shell, quickly diffuse and dilute the oxygen in the flame, thereby reducing the oxygen concentration in the flame and achieving the purpose of extinguishing the fire.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
