Abstract

The utility model relates to a protector of an energy-saving water dispenser. An A-point water level output is connected with a resistor R and a resistor R2 in parallel, the resistor R is grounded, the output of the resistor R2 is connected with an input/output (I/O) end of an integrated circuit (IC1) of a control circuit of a single chip computer, and a B-point water level is grounded; the resistor R1 is respectively connected with a key K1, a key K2 and a key K3 in series and is transported to the IC1 of the control circuit of the single chip computer to form into a keyboard operation circuit; when the water level in a water barrel of the water dispenser is reduced between the A-point water level and the B-point water level, a power voltage is used for dividing the pressure over the ground by a water conductive body through the resistor R2 and the resistor R, and the IC1 of the control circuit of the single chip computer has no signal output; and when the water level in the water barrel is reduced under the A-point water level to lead the A-point to be suspended, the power voltage is used for outputting the low level by the IC1 of the control circuit of the single chip computer rather than the water conductive body, a contactor KM is released, and the water dispenser is powered off. A drive circuit is controlled by the keyboard operation circuit, so that a power supply of the water dispenser can be powered off when the water is not enough, and the power supply of the water dispenser can be turned on or off within a set time, therefore, the protector of the energy-saving water dispenser is safe to use, convenient, energy-saving, and environment-friendly.
