All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
Referring to fig. 1, the fire extinguishing device with multipoint hot aerosol spraying comprises a shell 1, a temperature sensing detection starting line 2, an aerosol generating chamber 4 and a base 6;
the shell 1 is fixedly connected with the base 6 through a connecting piece, and a structure with a cavity is formed inside the shell; the aerosol generating chamber 4 is arranged in the cavity; the aerosol generating chamber 4 is of a circular structure, the shell 1 is of a square structure, and the aerosol generating chamber 4 and the shell 1 form a buffer space; the aerosol-generating chamber 4 is filled with an aerosol 5; seven nozzles are arranged on the upper surface of the aerosol generating chamber 4; correspondingly, ten nozzles are also arranged on the outer side surface of the shell 1.
The temperature-sensing detection starting line 2 penetrates through the shell 1 and is arranged in the shell 1, and one end of the temperature-sensing line penetrates through the shell 1 and the aerosol generating chamber 4 and then surrounds the periphery along a box cover; the heat-sensitive wire 2 abuts against the aerosol 5.
