AI Technical Summary
Technical Problem
Aerosol generating devices experience noise generation due to the introduction of low-frequency switch signals during the detection of electrical parameters, which degrades user experience.
Method used
Implementing a high-frequency pulse signal to control the heating operation of the heating element, accompanied by an interrupt request to accurately sample electrical parameters, thereby preventing noise interference.
Benefits of technology
Accurate sampling of electrical parameters is achieved without noise interference, enhancing user experience by improving the operational reliability of the aerosol generating device.

Abstract
An aerosol generating device and a control method therefor are provided, including: a battery core (20); a heating element (10), electrically connected to the battery core (20) to form a heating circuit; a sampling resistor (R1), electrically connected to the battery core (20) and the heating element (10) to form a sampling circuit; a switch transistor (Q1), configured to turn on or turn off the heating circuit and / or the sampling circuit; an analog-to-digital converter (ADC), configured to sample an electrical parameter of the sampling circuit; and a controller (31), configured to externally output a pulse signal for driving the switch transistor (Q1), to control a heating operation of the heating element (10), and further configured to generate an interrupt request and respond to the interrupt request to obtain the electrical parameter sampled by the ADC. The electrical parameter is accurately and effectively sampled through a high-frequency switch signal, to avoid a problem of the aerosol generating device generating noise as a result of a low-frequency switch signal being introduced into a circuit, thereby improving user experience.
