Please refer to FIG. 1 again. In the embodiment of the present application, the capacitance detection module 122 is electrically connected to the heating element 121 for obtaining the capacitance value of the heating element 121 in real time. It can be understood that, the specific structure of the heating element 121 is different, and the manner of electrical connection between the capacitance detection module 122 and the heating element 121 is also different.

For example, in the structure shown in FIG. 3 or 4, the capacitance detection module 122 can be electrically connected to the cylindrical substrate 1213, and in any of the structures shown in FIGS. 5-7, the capacitance detection module 122 can be electrically connected to the columnar substrate 1215. . The capacitance detection module 122 is electrically connected to the heating element 121 through a single wire, so that the atomization assembly 12 has a simple structure and is more convenient for production.

The atomization component 12 is started, and the substrate to be atomized is heated and atomized by the heating element 121 .

In other embodiments, when it is determined that the heating element 121 is provided with the substance to be atomized, the electronic atomization device can also directly control the start of the atomization component 12, and heat and atomize the substance to be atomized through the heating element 121, or it can be determined When the preset period of time after the heating element 121 is set for the substance to be atomized reaches, the electronic atomization device directly controls the atomization component 12 to start, and heats and atomizes the substance to be atomized through the heating element 121 . Wherein, the preset duration may be 10s or 15s or the like.

To sum up, it can be seen that the difference between the capacitance value of the heating element 121 acquired in real time and the reference capacitance value is obtained through the control module 123 of the atomization component 12, and according to the relationship between the capacitance difference value and the calibrated capacitance value interval, determine Whether the heating element 121 is provided with a substrate to be atomized, the heating element 121 is not easy to deform, so that the capacitance value of the heating element 121 acquired in real time is more accurate, so that the relationship between the tolerance value and the calibration capacitance value interval can be accurately determined, and then the accurate It is determined whether the heating element 121 is provided with a substance to be atomized.

At the same time, the capacitance detection module 122 is electrically connected to the heating element 121 through a single wire, which makes the structure of the atomization assembly simple, more convenient for design and production, and greatly reduces the cost of the atomization assembly.
