Solution Approach 1:

The patent implements feedback by having the control module continuously monitor the actual power output and compare it with the target power. Based on this feedback, the system dynamically adjusts the duty cycle in real-time, ensuring rapid response and high precision in maintaining constant power output, thereby eliminating the delays associated with periodic monitoring methods.

AI summary

An electronic atomization device includes: a heating element; and a control module for: controlling the heating element to heat in a heating period of a first time segment of a current time window, and detecting a resistance value of the heating element in a non-heating period of the first time segment of the current time window; controlling the heating element to heat in a heating period of an intermediate time segment of the current time window, and controlling the heating element to stop heating or detect the resistance value of the heating element in a non-heating period of the intermediate time segment of the current time window; and controlling the heating element to heat in a heating period of a final time segment of the current time window. The intermediate time segment is a different time segment than the first and final time segments in the current time window.
