In order to enable the aerosol generating agent grain to burn layer by layer, manufacturers generally adopt materials such as silica gel, rubber and plastic to manufacture a protective sleeve, the protective sleeve wraps the side surface of the aerosol generating agent, flame on the ignition end face of the aerosol generating agent grain is prevented from igniting the side wall of the grain, the starting surface of the aerosol generating agent is prevented from being suddenly increased, and then the gas production amount is increased, so that the internal pressure of the fire extinguishing device is suddenly increased, and the internal pressure of the fire extinguishing device is suddenly increased.
However, when the fire extinguishing device is in a fire scene, the starting failure of the starting wire harness or the failure of the controller/detector is unavoidable, so that the fire extinguishing device is not normally started, the overall temperature of the fire extinguishing device in the fire scene is gradually increased, when the temperature reaches the starting temperature of the aerosol generating agent, the heated surface (side surface of the powder) of the powder of the aerosol generating agent can suddenly burn and generate gas, and if the surface which reaches the preset temperature at first is a non-starting surface (the starting surface is the ignition end surface of the powder), the coating layer is invalid, so that the fire extinguishing device detonates. Therefore, an anti-explosion aerosol fire extinguishing device is designed.

Fig. 1 is a schematic structural view of an aerosol fire extinguishing apparatus for preventing knocking.
Detailed Description
The utility model is described in further detail below with reference to the drawings and the specific examples.
As shown in fig. 1, an anti-explosion aerosol fire extinguishing device comprises an outer cylinder 1 and a fire extinguishing agent grain 2 arranged in the outer cylinder 1, wherein the fire extinguishing agent grain 2 is matched with the tail end of a starting component 3, the fire extinguishing agent grain 2 or the starting component 3 is also matched with one end of a temperature sensing and heat sensing component 6, and the other end of the temperature sensing and heat sensing component 6 is close to or in contact with the inner side wall of the outer cylinder 1.
Preferably, the front cover 4 surface of the outer barrel 1 is provided with a nozzle 5, and a silica gel sleeve 11 for heat insulation is arranged between the fire extinguishing agent grain 2 and the inner side wall of the outer barrel 1.
In the above technical solution, if the fire extinguishing device fails to start (for example, the starting wire harness fails to start or the controller/detector fails), then as the temperature of the fire extinguishing device in the fire scene gradually increases, the surface temperature of the outer cylinder 1 gradually increases, the temperature of the surface of the outer cylinder 1 can be quickly sensed because the other end of the temperature sensing and sensing assembly 6 is close to or in contact with the inner side wall of the outer cylinder 1, and the temperature of the fire extinguishing material can be quickly sensed because the ignition temperature of the temperature sensing and sensing assembly 6 is far less than the ignition temperature of the fire extinguishing material column 2, so that after the temperature rises to a certain value, the temperature sensing and sensing assembly 6 is first ignited, then the ignition end face of the fire extinguishing material column 2 is ignited (or the temperature sensing and sensing assembly 6 is first caused to cause the starting member 3 to start, then the fire extinguishing material column 2 is ignited from the ignition end face of the fire extinguishing material column 2, and fire extinguishing material is released from the ignition end face layer by layer, and then the fire extinguishing material is ejected from the nozzle 5. In the process that the temperature sensing and heat sensing assembly 6 is ignited to ignite the ignition end face of the fire extinguishing agent grain 2, the side face of the fire extinguishing agent grain 2 is not ignited, so that the phenomenon of deflagration does not occur.
Preferably, the rear end of the outer cylinder is provided with a rear cover 7, and the surface of the rear cover 7 is provided with a threading pipe 8. The harness passing through the starting member 3 can be protected by the harness pipe 8.
Preferably, a protective film 9 is also attached to the surface of the front cover 4. After the design, the phenomenon that moisture in the air enters the outer cylinder 1 through the nozzle 5 to cause the moisture absorption of the extinguishing agent grain 2 can be prevented in the storage and transportation process of the extinguishing device.
Preferably, the area between the ignition end face of the extinguishing agent column 2 and the front cover 4 is filled with a coolant 10. By providing the coolant 10, the high-temperature fire extinguishing substance generated by the fire extinguishing agent column 2 can be cooled, so that the temperature at the nozzle 5 of the fire extinguishing device is not too high after the fire extinguishing substance is discharged from the nozzle 5.
Preferably, the starting part 3 is an electric ignition head or a heat-sensitive wire structure. When the starting means 3 is of an electric ignition head construction, it can be connected to a fire detection device, which is a temperature sensor and/or a smoke sensor. When fire, overheat and other conditions occur, the fire detection device detects the high-temperature environment generated by the fire in the battery compartment and then sends a signal to the microprocessor, and the microprocessor controls the starting component 3 to ignite the fire extinguishing agent grain 2. When the starting component 3 is of a thermosensitive line structure, the thermosensitive line structure can be directly ignited when a fire disaster occurs, and then the fire extinguishing agent grain 2 is directly ignited, so that an additional fire disaster detection device and other external devices are not needed, and the device is simpler and lower in cost.
Preferably, the other end of the temperature-sensing thermosensitive assembly 6 extends into a gap between the outer surface of the silica gel sleeve 11 and the inner side wall of the outer cylinder 1. After the design, the device for fixing the temperature-sensing and heat-sensing assembly 6 on the surface of the inner side wall of the outer barrel 1 is not needed to be additionally arranged, and the temperature-sensing and heat-sensing assembly 6 can be directly pressed on the inner side wall of the outer barrel 1 through the extrusion force of the silica gel sleeve 11.
Preferably, the fire extinguishing agent column 2 is a column structure formed by pressing aerosol generating agent powder. The aerosol generating agent pressed into the column structure burns slower than the powdery aerosol generating agent, and can ensure the sustained release of the fire extinguishing substance.
The working principle of the embodiment is as follows:
When a fire occurs in the outside, if the fire extinguishing device fails to start (for example, the starting wire harness fails to start or the controller/detector fails), the surface temperature of the outer cylinder 1 gradually increases as the temperature of the fire extinguishing device in the fire scene gradually increases, and since the ignition temperature of the temperature sensing and heat sensing assembly 6 is far less than the ignition temperature of the fire extinguishing agent grain 2, after the temperature rises to a certain value, the temperature sensing and heat sensing assembly 6 is ignited first, and then the ignition end face of the fire extinguishing agent grain 2 is ignited, so that a starting process is realized from the ignition end face of the fire extinguishing agent grain 2, the fire extinguishing agent grain 2 burns layer by layer from the ignition end face and releases fire extinguishing substances, and then is sprayed out from the spray nozzle 5 to perform a fire extinguishing process.
The above embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments of the present utility model may be arbitrarily combined with each other without collision. The protection scope of the present utility model is defined by the claims, and the protection scope includes equivalent alternatives to the technical features of the claims.
