An improved cold and warm
fog humidifier comprises a
machine body and a water tank arranged at the top of the
machine body, a water tank communicated with the water tank is arranged in the
machine body, an
evaporation cavity, a cold
fog cavity and a
fog discharging pipeline are arranged in the machine body, the water tank is communicated with the
evaporation cavity and the cold fog cavity, a heating device is arranged at the bottom of the
evaporation cavity, and a cold fog generator is arranged at the bottom of the cold fog cavity. The mist discharging pipeline is communicated with the evaporation cavity and the cold mist cavity, and the evaporation cavity is directly communicated with the mist discharging pipeline. The positions of the original evaporation cavity and the original cold fog cavity are exchanged, the evaporation cavity is directly communicated with the fog discharging pipeline, hot fog steam generated in the evaporation cavity can be directly discharged into the fog discharging pipeline, therefore, the hot fog steam cannot be condensed, the flowing speed of the hot fog steam can be increased, cold fog generated in the cold fog cavity is discharged into the fog discharging pipeline through the cold fog pipeline, and the cold fog discharging effect is improved. The cold fog is discharged out of the humidifier after being mixed with the hot fog steam, and the cold fog cannot be condensed, so that the fog outlet efficiency of the humidifier can be improved, the temperature of the discharged fog is moderate, and the fog outlet effect is greatly improved.
