mine tunnel; the
humidity adjusting structure is arranged in the water washing box and used for adjusting and controlling the air supply
humidity of the air supply structure. Compared with the prior art, the
air purifier has the advantages that the water washing box is arranged,
clean water is used for filtering and adsorbing air supply dust, the internal
clean water can be replaced, a
filter element does not need to be frequently replaced, and the
air purifier is more convenient to use; the air supply
humidity can be adjusted and controlled by controlling the opening degree of the two air valves, and the situation that the normal operation and safe use of
electrical equipment are affected due to the fact that the
