As for the humidity, the water electrodes can increasingly high concentrations of easily generated scale, the impact of the effect of steam generated, so in accordance with set procedures, the main control of the controller will work in the host after a certain period of time to open the drainage valve (according to different drainage water cycle settings), ranked out of high concentrations of water, automatically add new water to ensure a good humidifier humidification efficiency, and extend the useful life of the host.

随着加湿的进行，电极罐中的水浓度越来越高，极易产生水垢，影响蒸汽产生效果，因此根据程序设置，主控制控制器将在主机工作一定时间后打开排水阀（可根据不同水质设定排水周期），排掉高浓度的水，自动补充新水，确保加湿器良好的加湿效率以及延长主机使用寿命。
