Solution Overview
Problem
Existing electronic vaporization devices face issues with dry heating, which can damage the atomizing sheet, reduce vaporization performance, and lead to a loss of vaporization function, and current detection methods are inadequate for detecting dry heating caused by poor liquid supply.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If temperature detection is performed during user suction, then dry burning detection is timely, but it causes delay effect and affects user experience
Solution Approach 1:
The patent performs dry burning detection before the heating component is activated for user suction, rather than during suction. This preliminary detection approach allows the system to identify dry burning conditions before they affect user experience, while avoiding detection delays during actual usage. The method calculates temperature based on resistance values obtained before heating starts, ensuring timely detection without interfering with the suction process.
2Measurement precision
If sensors such as probes are used to contact medicinal liquid for detection, then liquid level can be detected, but detection accuracy is reduced and device complexity increases
Solution Approach 1:
The patent replaces mechanical contact sensors (probes) with an electrical measurement approach. Instead of using physical sensors to detect liquid level, the system measures the resistance value of the heating component, which changes based on whether liquid is present. This substitution eliminates the need for additional mechanical sensors, reduces device complexity, and maintains high detection accuracy by utilizing the inherent electrical properties of the heating element.
Solution Approach 2:
The heating component serves dual purposes: it functions as both the heating element and the detection sensor. The resistance value of the heating component itself provides information about liquid presence, eliminating the need for separate detection sensors. This self-service approach simplifies the device structure while maintaining accurate detection capabilities.

AI summary
This application discloses a vaporization state recognition method, an apparatus, an electronic device and a storage medium. The vaporization state recognition method including: obtaining (S1) a heating rate of an atomizing sheet of a vaporizer; and determining (S2) a vaporization state of the vaporizer according to the heating rate. Therefore, whether the vaporizer is dry heating may be recognized in time and the dry heating of the vaporizer may be dealt with in time. In addition, during recognizing the vaporization state of the vaporizer, there is no need to use a sensor such as a probe to contact medicinal liquid, so that a detection is more accurate.
