Drainage device of moisture regaining machine and moisture regaining machine

The embodiment of the utility model provides a drainage device of a damping machine, which comprises a main pipeline of which the liquid inlet end is communicated with the water outlet end of the damping machine and the liquid discharge end is communicated with a condensate water recycle bin; the flow meter is arranged on the main pipeline and used for detecting the actual flow speed of water flow in the main pipeline; the booster pump is arranged on the main pipeline, and the booster pump is located between the flow meter and the liquid discharge end of the main pipeline; the control system is electrically connected with the booster pump and the flow meter and used for receiving the actual flow speed detected by the flow meter and controlling the booster pump to start boosting when the actual flow speed is smaller than the preset flow speed. The condensate water discharging efficiency can be improved, and tobacco shreds are prevented from being wetted by the condensate water. The utility model further provid
