Personal Thermal Device in Detail

  1. Heat control dialTurn the dial to set the heating temperature (levels 1 to 9) Operation lamp lights up while the heating wire is heating
  2. Heating buttonStarts the heating function (8 hours is selected automatically, so the 8-hour lamp lights up, and the heating lamp lights up)
  3. Time setting buttonPress the button to cycle through 3, 6, and 8 hours
  4. Power switchPower switch ON (power lamp lights up)

Operating Principle

Part of the supplied AC220V power goes to the heating wire, while the rest passes through a rectifier circuit to become DC12V and then through a constant-voltage circuit to become
DC5V, which powers the microcontroller and peripheral circuits. Once reset by the power supply, the microcontroller controls function execution and the display according to the power switch and
temperature control dial inputs.

When the heating unit is turned ON with the heating button and a temperature is set, AC220V power is supplied to drive the heating wire, and heating operation is controlled by switching the triac
ON/OFF. Once the user sets the desired temperature, the temperature sensor detects the temperature and the heater
repeatedly turns off when it rises above the set temperature and on when it falls below it, maintaining the set temperature. In case of overheating, a bimetal switch
is activated to prevent overheating.
