[0018] 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 of 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.

[0019] See also Figure 1-2 The utility model provides a technical solution: a perfluorohexanone self-inductive fire extinguishing patch, comprising a base fabric layer 1, a first adhesive layer 2 is bonded to the base fabric layer 1, a waterproof layer 3 is bonded to the side of the first base fabric layer 1 away from the first adhesive layer 2, a first fireproof layer 4 is bonded to the end of the waterproof layer 3 away from the base fabric layer 1, a second adhesive layer 5 is bonded to the end of the first fireproof layer 4 away from the waterproof layer 3, a second fireproof layer 6 is bonded to the side of the second adhesive layer 5 away from the first fireproof layer 4, a first fire extinguishing capsule 7 and a second fire extinguishing capsule 8 are bonded to the side of the second fireproof layer 6 away from the second adhesive layer 5 in sequence, a connecting layer 9 is bonded to the side of the second fire extinguishing capsule 8 away from the first fire extinguishing capsule 7, and a third fire extinguishing capsule 10 and a fourth fire extinguishing capsule 11 are bonded to the end of the connecting layer 9 away from the second fire extinguishing capsule 8 in sequence.

[0020] Specifically, the first adhesive layer 2 is made of silicone adhesive, so that the first base fabric layer 1 can be firmly adhered to the desired place. The second adhesive layer 5 is made of resin-type pressure-sensitive adhesive, which is consistent with the composition of double-sided adhesive, so that the second fireproof layer 6 can be easily torn off from the second adhesive layer 5, making it convenient to replace a new fire extinguishing bag.

[0021] Specifically, the waterproof layer 3 is made of polytetrafluoroethylene to improve the waterproof performance of the fire extinguishing patch. The first fireproof layer 4 and the second fireproof layer 6 are made of glass fiber and are coated with high-temperature resistant paint on the surface. The first fireproof layer 4 and the second fireproof layer 6 are arranged to prevent the flame from burning the second adhesive layer 5 and the base fabric layer 1.

[0022] Specifically, the first fire extinguishing bag 7, the second fire extinguishing bag 8, the third fire extinguishing bag 10 and the fourth fire extinguishing bag 11 are all distributed in a rectangular array to ensure that the fire extinguishing bag covers the fire extinguishing patch in an all-round manner, thereby increasing the fire extinguishing range.

[0023] Specifically, the capsules of the second fire extinguishing bag 8 and the fourth fire extinguishing bag 11 have a shell layer made of gelatin, and the capsules of the first fire extinguishing bag 7 and the third fire extinguishing bag 10 have two shell layers, one shell layer is made of gelatin, and the other shell layer is made of epoxy resin. When a fire source appears, the fourth fire extinguishing bag 11 is burned first, and the perfluoroacetone gas in the fire extinguishing bag 11 extinguishes the flame. The double-layer shell setting of the third fire extinguishing bag 10 prevents the third fire extinguishing bag 10 from being burned when the fourth fire extinguishing bag 11 is used, thereby increasing the number of uses of the fire extinguishing patch. The settings of the first fire extinguishing bag 8 and the second fire extinguishing bag 8 are the same as above, which can increase the number of uses of the fire extinguishing patch and can be used to extinguish fires in time when multiple fires occur.

[0024] Specifically, the connecting layer 9 is made of polyethylene, and the melting point of polyethylene is 100°C. The connecting layer 9 can prevent the second fire extinguishing bag 8 from being burned when the flame burns the third fire extinguishing bag 10. The second fire extinguishing bag 8 will not be burned until the fire breaks out again and burns the connecting layer 9. Under ideal conditions, a fire extinguishing patch can be used at least four times, so that it can extinguish fires in time when multiple fires occur and has high durability, thereby improving reliability of use.

[0025] A specific application example of this embodiment is:

[0026] When the device is in use, the fire extinguishing patch is attached to the desired place through the first adhesive layer 2, the waterproof layer 3 improves the waterproof performance of the fire extinguishing patch, and the first fireproof layer 4 and the second fireproof layer 6 are arranged to prevent the flame from burning the second adhesive layer 5 and the base fabric layer 1. When a fire source appears, the fourth fire extinguishing bag 11 is burned first, and the perfluoroacetone gas in the fire extinguishing bag 11 extinguishes the flame to achieve a self-induction fire extinguishing effect. The double-layer shell arrangement of the third fire extinguishing bag 10 can prevent the third fire extinguishing bag 10 from being burned when the fourth fire extinguishing bag 11 is used, thereby increasing the number of times the fire extinguishing patch is used. When a fire occurs again, the third fire extinguishing bag 10 is burned to release the perfluoroacetone gas to extinguish the flame. The fire extinguishing patch can be used for at least four times, so that fires can be extinguished in time when multiple fires occur, and the durability of use is high, thereby improving the reliability of use. After the first fire extinguishing patch 7, the second fire extinguishing patch 8, the third fire extinguishing patch 10 and the fourth fire extinguishing patch 11 are all used, the second fireproof layer 6 can be torn off through the second adhesive layer 5, and a new fire extinguishing patch can be replaced. The replacement is convenient, and the waste of materials can be reduced. It can also avoid the fire extinguishing patch being pasted too many times at the fire extinguishing location to cause glue stains to remain, affecting the appearance.
