Sclosed is a water level control apparatus for a micro-mist sauna apparatus, comprising: a humidifying part, a water reservoir, a water supply pipe and a valve thereof and a water discharge pipe and a valve thereof, a DC power supply, a microprocessor, and an electrical motor, wherein the humidifying part is connected to and provided on the electrical motor electricity is supplied to the electrical motor by the DC power supply and an electrical current monitoring apparatus monitoring the value of the electrical current of the electrical motor in real-time is further provided in the electrical circuit. When the electrical current monitoring apparatus detects that the present electrical current value of the electrical motor is lower than a preset minimum electrical current value, the microprocessor controls the opening of the water supply pipe valve and controls the shutting of the water discharge pipe valve until the added value &DgrIm of the present electrical current reaches a preset value Ic or the present electrical current value reaches the preset electrical current value, at which point the microprocessor controls the closing of the water supply pipe valve. When the electrical current monitoring apparatus detects that the present electrical current value of the electrical motor is higher than a preset minimum electrical current value, and lower than a preset maximum electrical current value, the microprocessor controls the continued running of the electrical motor, and controls the closing of both the water supply pipe valve and the water discharge pipe valve. The advantage of the present invention is convenient and prompt monitoring and control of the water level.本發明係有關於一種微霧桑拿裝置的水位控制裝置,其包括:加濕部、蓄水槽、供水管及其閥門和排水管及其閥門、直流電源、微處理器、電機,所述加濕部連接設置於電機上,所述的電機由所述的直流電源提供電力,電路中還具有即時監測電機電流值的電流監測裝置;當電流監測裝置監測得到的當前電機電流值低於預設的最低電流值時,微處理器控制供水管閥門開啟,控制排水管閥門關閉,直到當前電流增加值△Im達到預設值Tc時或者當前電流值達到預設的電流值時,微處理器才控制供水管閥門關閉;當電流監測裝置監測得到的當前電機電流值高於預設的最低電流值,並且低於預設的最高電流值的時候,微處理器控制電機保持運轉,控制供水管閥門和排水管閥門都關閉。
