Electrical heating module and power supply control method thereof

A personal vaping device, comprising:

• an electrical heating module that is an atomizer configured to atomize electronic cigarette liquid;
• and
• a power supply control circuit configured to supply power to the electrical heating module,
• wherein the power supply control circuit comprises:
• a current input terminal configured to be connected to a direct current (DC) power supply;
• a current output terminal separated from the current input terminal and configured to be connected to the electrical heating module;
• and
• a power supply control module arranged between the current input terminal and the current output terminal,
• wherein the power supply control module is configured to control connection and disconnection of the current output terminal with the electrical heating module, and to convert a DC from the DC power supply into a supply current having a periodic variation in at least one of a direction, an instantaneous value, or an on-state time,
• wherein the power supply control module comprises a voltage modulation module, a microprocessor, and a forward and reverse connection current generation module,
• wherein the microprocessor is configured to control the voltage modulation module and the forward and reverse connection current generation module;
• and
• wherein the voltage modulation module is configured to regulate a voltage of the DC power supply to a first target voltage and a second target voltage, and couple the second target voltage to the forward and reverse connection current generation module, wherein the first target voltage is configured to control on and off of the forward and reverse connection current generation module.
