Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is a schematic diagram of the structure of the present utility model after the operation.
Detailed Description
As shown in fig. 1, the aerosol fire extinguishing device for preventing false start comprises a composite detector 1 and an aerosol fire extinguishing device 2 which are arranged in a battery pack, and further comprises a pipe 3, wherein a first wiring terminal 4 is arranged in the middle of the pipe 3, a second wiring terminal 5 is arranged at the bottom of the pipe, the first wiring terminal 4 is used for being electrically connected with the composite detector 1, the second wiring terminal 5 is used for being electrically connected with the aerosol fire extinguishing device 2, and a wire 6 connected into the pipe 3 is arranged on each of the first wiring terminal 4 and the second wiring terminal 5;
a fusible metal sheet 7 is arranged in the pipe 3 above the second wiring end 5, and a conductive liquid 8 is filled in the pipe 3 above the fusible metal sheet 7. When the temperature reaches the melting temperature of the fusible metal sheet, the fusible metal sheet at the bottom of the pipe is melted, the conductive liquid is lowered, the output current of the composite detector passes through, and after the current is induced by the starting line of the aerosol fire extinguishing device 2, the aerosol fire extinguishing device 2 is started. Thereby preventing the false start of the housing from playing a role in preventing and interrupting the false discharge of the fire extinguishing device.
Preferably, the fusible metal sheet 7 is made of a bismuth-based fusible alloy having a melting point of 47 ℃.
Preferably, the pipe 3 is made of an insulating material.
Preferably, the tube 3 is provided with two. The two pipes 3 correspond to the two output ends of the composite detector 1, and have the effect of double-path action.
Preferably, two tubes 3 are provided in the housing 9, and a partition 10 is provided in the middle of the housing 9 to separate the two tubes 3.
Preferably, the composite detector 1 includes a smoke sensing module, a voc module and a temperature sensing module. Preferably, the composite detector 1 adopts a v6726c fire prevention and control sensor.
The electroconductive liquid may be selected as the electroconductive liquid as long as it is an aqueous solution of a substance belonging to the acid-base salt type, and is put into the pipe 3. The two ends of the pipe 3 are directly fixed inside the shell. When the composite detector detects that the smoke sensing module, the voc module and the temperature sensing module reach alarm values, current can be output, the current is output to the inside of the pipe, the conductive liquid in the pipe is heated, the conductive liquid 8 is lowered after the fusible metal sheet reaches the melting temperature, as shown in fig. 2, the first wiring terminal 4 and the second wiring terminal 5 are conducted, the current can be output to the aerosol fire extinguishing device 2 through the pipe, and the aerosol fire extinguishing device 2 is started.
