Trigger the switch of pump body 121, extract the additive above the separation ring 18 and inject it into the bottom to mix with the circulating water. The mixed liquid is transported downward through pump body 22 and sprayed out through the atomizing nozzle 24. After being sprayed and treated with additives, the exhaust gas continues to rise and passes through the activated carbon plate 31.
