A solution purification assembly is provided in the installation chamber at a position downstream of the primary filter portion 10, the solution purification assembly including a purification portion 31 and a liquid ejection portion 38, the liquid ejection portion 38 for ejecting a salt solution to the purification portion 31. The fan 70 is located in the mounting cavity and disposed near the air outlet for drawing air into the air inlet. The heating structure 21 is used for heating the salt solution to evaporate water in the salt solution into water vapor. Wherein the heating structure 21 is activated to place the solution purification assembly in a dehumidification mode.

By applying the technical scheme of the embodiment, when the gas needs to be sterilized, the fan 70 and the liquid spraying part 38 are started, the fan 70 sucks the gas into the installation cavity through the air inlet, and the saline solution is sprayed on the purification part 31 through the liquid spraying part 38 so as to contact the saline solution with the gas.

Alternatively, the primary filter unit 10 may be a plate type or a folded type, and a nonwoven fabric is preferable. Thus, the primary filtering part 10 can filter some large-particle impurities, and prevent the purification effect from being influenced by the blockage in the purification part 31.

As shown in fig. 1, the liquid spraying part 38 includes a liquid inlet pipe 381 and a spraying head 382 communicated with the liquid inlet pipe 381, and the solution purifying assembly further includes a buffer structure 32. The buffer structure 32 is used for storing a salt solution, and the buffer structure 32 is communicated with the liquid outlet of the purifying part 31 and the liquid inlet pipeline 381. In this way, the saline solution discharged from the purifying part 31 enters the buffer structure 32 again, and enters the liquid spraying part 38 again through the buffer structure 32, so that the energy waste is reduced, and the energy utilization rate is improved. Meanwhile, the arrangement makes the structure of the liquid spraying part 38 simpler, and the processing and the realization are easy, thereby reducing the processing cost of the liquid spraying part 38.
