For example: present indoor when the condition of a fire, and the regional scope of conflagration is not big, can select the relatively great fire extinguishing liquid section of thick bamboo 3 of volume to assemble to the powder section of thick bamboo 2 of putting out a fire, and then form the outer layer of relatively thick liquid fog layer of putting out a fire, reduce the regional scope to the regional scope of conflagration that the powder of putting out a fire atomizing spread to realize putting out of the condition of a fire, the regional scope that powder, the liquid of putting out a fire scatter down simultaneously is less relatively, easily clears up, and is little to all ring edge border health. For example: when the regional scope of the condition of a fire isochronal, can select the relatively medium fire extinguishing fluid section of thick bamboo 3 of volume and assemble to the powder section of thick bamboo 2 of putting out a fire, and then form the outer fire extinguishing fluid atomization layer of relative medium thickness, the regional scope control of the powder cigarette atomizing diffusion of putting out a fire is in the regional scope of conflagration to realize putting out of the condition of a fire, the regional scope phase-match that powder, the liquid of putting out a fire scatter down simultaneously with the regional scope of conflagration, and then reduce the work load of the clearance work after the conflagration is put out. For example: when the regional scope of condition of a fire is great relatively, can select the relatively less fire extinguishing fluid section of thick bamboo 3 of volume to assemble to the powder section of thick bamboo 2 of putting out a fire, and then form the outer fire extinguishing fluid atomization layer that relative thickness is thinner, the regional scope control of powder cigarette atomizing diffusion of putting out a fire expands to the regional scope of conflagration even slightly outside in the regional scope of conflagration, thereby realize putting out of the condition of a fire, the regional scope suitable control that falls down to powder of putting out a fire simultaneously, and then the work load of the clearance work after the reduction conflagration is put out. For example: when the area range of the fire is very large and difficult to control, the fire extinguishing liquid cylinder 3 is directly cancelled, and the liquid powder double-layer fire extinguishing bomb is thrown into a fire scene to be detonated, so that the fire is relieved; by gradually or simultaneously putting a plurality of liquid powder double-layer fire extinguishing bombs without the fire extinguishing liquid cylinder 3, the fire condition is gradually relieved, a barrier wall is formed after the smoke of the fire extinguishing powder is diffused, and even the fire is thoroughly extinguished.
