in the water source fire extinguishing process, a second air extractor (40) sequentially extracts smoke generated by combustion at the upper end of the room through a fifth gas transmission pipeline (20) and a third gas transmission pipeline (16), and the smoke enters a second smoke treatment cavity (11) to enter and contact with a purifying liquid in the second smoke treatment cavity (11) to purify particles in the smoke;
step four, extracting the gas purified in the second smoke treatment frame (9) through a first air extracting device (39) by a sixth gas transmission pipeline (21), enabling the smoke to enter a first smoke treatment cavity (10) in the first smoke treatment frame (8), starting an electronic igniter (12) and enabling a fire source to be discharged through an ignition port (14), combusting the passed gas, enabling the oxygen content in the gas to be reduced, conveying the gas through a second gas transmission pipeline (13) after the oxygen content is reduced, and splitting the gas by a fourth gas transmission pipeline (17), and discharging the split gas through a smoke extraction head (24), wherein the gas with lower oxygen content directly contacts the position of the fire source, and inhibiting continuous combustion and spreading of the fire source;
and fifthly, when the gas is exhausted and extracted, the gas enters the second gas flow cavity (32) from the first gas flow cavity (31) after being limited by the waterproof cover (23) and the waterproof ring (29), and the foreign matters entering the second gas flow cavity (32) due to the adsorption force are limited by the first waterproof connecting pipes (27) and the second waterproof connecting pipes (28) which are distributed in a crossed way, so that the entry of the foreign matters is limited under the condition that the gas flow is not limited.
