[0018] Figure 3 This is a schematic diagram of the mounting structure of the propellant cartridge groove inside the casing. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-3 As shown, a power-off device combined with a fire extinguishing agent column includes a housing 1 mounted on an electric wire 2. The housing 1 has a column groove 4 for fixing the fire extinguishing agent column 3. The top of the column groove 4 is open and the electric wire 2 is located above the column groove 4. The fire extinguishing agent column 3 is connected to an activation component. The surface of the housing 1 is provided with a discharge port 5.

[0021] Preferably, such as Figure 2 As shown, the outer casing 1 includes an upper casing 1.1 and a lower casing 1.2, with one side of the upper casing 1.1 hinged to one side of the lower casing 1.2. This split hinge structure simplifies the installation or removal of the outer casing 1 on the surface of the wire 2; more preferably, one side of the upper casing 1.1 and one side of the lower casing 1.2 are hinged by a spring hinge.

[0022] Preferably, the position where the upper shell 1.1 and the lower shell 1.2 contact is provided with a groove 1.3 matched with the electric wire 2. The groove 1.3 can limit the position of the outer shell 1 on the surface of the electric wire 2.

[0023] Preferably, the position of the groove 1.3 is further fixedly provided with a rubber layer 1.4. The rubber layer 1.4 can increase the friction between the electric wire 2 and the groove 1.3, so that the outer shell 1 cannot slip along the direction of the electric wire 2.

[0024] Preferably, the top of the cartridge groove 4 is provided with a positioning groove 4.1 matched with the electric wire 2. The positioning groove 4.1 can make the electric wire 2 in good contact with the cartridge groove 4, so as to ensure that the electric wire 2 is located above the cartridge groove 4.

[0025] Preferably, the fire extinguishing agent cartridge 3 is a cartridge structure pressed by an aerosol generating agent powder. When the aerosol generating agent burns, a large amount of aerosol fire extinguishing material is released, and heat is also generated. The high temperature brought by the heat can burn the electric wire 2, and the released aerosol fire extinguishing material can be sprayed out of the spray port 5 to extinguish the fire in the peripheral area of the outer shell 1.

[0026] Preferably, the starting component is a thermal sensitive wire structure or an electric starter structure. When the starting component is a thermal sensitive wire structure, the flame can directly ignite the thermal sensitive wire when a fire occurs in the outside world, so as to ignite the fire extinguishing agent cartridge 3. When the starting component is an electric starter structure, it includes an electronic ignition head and a starting wire harness. The electronic ignition head is in contact with one end of the fire extinguishing agent cartridge 3. One end of the starting wire harness is connected with the electronic ignition head, and the other end penetrates through the wire hole and is connected with an external power supply. When the starting component is an electric ignition head structure, it is further provided with a fire detection device. The fire detection device is a temperature sensor and / or a smoke sensor. When a fire, overheating or other situation occurs, the fire detection device detects the high temperature environment generated by the fire in the outside world, sends a signal to a microprocessor, and the microprocessor controls the external power supply to work, so as to make the electronic ignition head ignite, and then ignite the fire extinguishing agent cartridge 3.

[0027] Preferably, as shown in Figure 3 The gap between the outer shell 1 and the cartridge groove 4 is further filled with a coolant 6. The coolant 6 can be a physical coolant and / or a chemical coolant. The physical coolant can be one or more combinations of iron filings, ceramic balls and goose warm stones. The chemical coolant can be one or more combinations of potassium nitrate, potassium bitartrate and ferrocene. The coolant 6 can prevent the heat generated by the electric wire 2 and the heat generated by the combustion of the fire extinguishing agent cartridge 3 from being released to the outside of the outer shell 1.

[0028] The working principle of the embodiment is as follows:

[0029] When the electric appliance is on fire due to short circuit, the starting part ignites the extinguishing agent pill 3 (for example, an aerosol generating agent pill) to release a large amount of heat and aerosol extinguishing material, the high temperature caused by the heat can burn the electric wire 2 to quickly cut off the electric wire, and the aerosol extinguishing material released can be sprayed from the spray opening 5 to perform the extinguishing process on the peripheral area of the shell 1.

[0030] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as a limitation of the present application. The protection scope of the present application should be based on the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features recorded in the claims.
