The foam sprayed by the fine mist foam extinguisher can adhere to the combustible materials, isolating the combustible materials from the air and achieving the effect of extinguishing the fire.

[0003] According to the application number: CN202322089936.3, a portable foam fire extinguisher car is disclosed. The portable foam fire extinguisher car can make the placement and removal of the foam agent tank more convenient through the side rods hingedly installed on the base plate through the hinge block. The connection of adjacent side rods can be completed through the coordinated clamping installation of the side grooves, the top grooves and the reinforcement plates, and the side rods can be limited and fixed. Through the coordinated use of the cache mechanism, the placement plate and the buffer plate, the bottom and sides of the foam agent tank can be buffered to prevent the foam agent tank from being shaken continuously due to bumps, thereby improving the safety of the foam agent tank.
