Heat preservation system and smart cup using same
First Claim
1. A heating preservation system comprising:
- a selected unit configured to select a preset temperature from amongst a plurality of differing preset temperatures, each preset temperature corresponding to a preset voltage;
a control unit configured to send the preset voltage according to the selected preset temperature;
a detection unit configured to detect a temperature of a fluid and convert the temperature to a detected voltage;
a comparison unit configured to receive the preset voltage and the detected voltage and compare the detected voltage with the preset voltage; and
a heating unit 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;
wherein the detection unit comprises a pull-up resistor and a thermistor, a first end of the pull-up resistor is coupled to a high level voltage, a second end of the pull-up resistor is coupled to a first end of the thermistor, a second end of the thermistor is grounded.

Abstract
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.
