A heating preservation system includes a selected unit, a control unit, a detection unit, and a heating unit. The selected unit is configured to select a preset temperature from amongst a plurality of differing preset temperatures, each preset temperature corresponds to a preset voltage. The control unit is configured to send out the preset voltage according to the selected preset temperature. The detection unit is configured to detect a temperature of fluid and convert the temperature to a detected voltage. The comparison unit is configured to receive the preset voltage and the detected voltage and compare the detected voltage with the preset voltage. The heating unit is configured to heat the fluid when the detected voltage is less than the preset voltage, and stop heating the fluid when the detected voltage is more than the preset voltage. A smart cup using the heating preservation system is further disclosed.

A power supply system includes a power supply unit, a voltage converting unit, a comparison unit, and a switching unit. The power supply unit is configured to provide working voltage for a motherboard via a first resistor. The voltage converting unit includes a voltage converting chip. The voltage converting chip is configured to detect a first direct current (DC) voltage on the first resistor, and convert the first DC voltage to a second DC voltage. The comparison unit is configured to receive the second DC voltage, compare the second DC voltage with the working voltage, and output a switch signal. The switching unit is configured to receive the switch signal, and output a control signal to a central processing unit (CPU) on the motherboard according to the switch signal. The CPU is configured to adjust its frequency according to the control signal.
