Humidity regulation and control device

The utility model relates to the technical field of material processing devices, in particular to a humidity regulation and control device. The humidity regulation and control device comprises an air supply system, a humidification system and an air injection system which are sequentially connected through pipelines. The gas distributor is arranged in the gas injection system to mix gas, so that the humidity of the gas humidified by the humidifying system is more uniform, and the microporous filter plate with the pore diameter of 1-10 microns is further arranged, so that the gas mixed by the gas distributor can be mildly injected to the surface of a workpiece to be subjected to humidity regulation and control. The humidity regulation and control device is particularly suitable for materials which are prone to deformation, such as a coating formed by paint, so that bad appearance cannot be formed on the surface of the coating subjected to humidity regulation and control, and meanwhile, resistance distribution
