Electronic atomizer, tar content state detection method and device for liquid storage cavity and storage medium

Abstract

The invention relates to an electronic atomizer, a tar content state detection method and device for a liquid storage cavity and a storage medium. The electronic atomizer comprises the liquid storagecavity used for storing tobacco tar, an atomizing core used for heating and atomizing the tobacco tar in the liquid storage cavity, a resonant unit and a processing unit, wherein the resonant unit comprises a resonant capacitor, a resonant coil and an excitation source; the resonant unit is arranged outside the liquid storage cavity; the tobacco tar in the liquid storage cavity is used as a dielectric of the resonant capacitor or the resonant coil; the excitation source is used for outputting an excitation signal to enable the resonant unit to resonate when no tobacco tar exists in the liquidstorage cavity; and the processing unit is used for determining the tobacco tar content state of the liquid storage cavity according to a detection electric signal output by the resonant unit under the excitation of the excitation source. The resonance unit is arranged outside the liquid storage cavity, the tobacco tar in the liquid storage cavity is used as the dielectric of the resonant capacitor or the resonant coil in the resonant unit, the change of the tobacco tar causes the change of complex impedance of the resonant unit, and the processing unit can determine the tobacco tar content state of the liquid storage cavity through the detection electric signal.

Description

technical field [0001] The present application relates to the technical field of electronic cigarettes, in particular to an electronic atomizer, a detection method, device and storage medium for an oil state in a liquid storage cavity. Background technique [0002] Electronic cigarettes are also known as virtual cigarettes and electronic atomizers. E-cigarettes as an alternative to cigarettes. Electronic cigarettes have similar appearance and taste to cigarettes, but generally do not contain other harmful components such as tar and suspended particles in cigarettes. [0003] Among them, the electronic atomizer generally includes a liquid storage component, an atomization component and a battery component. In the existing electronic atomizer, in order to prevent the generation of harmful substances and burnt smell, it needs to be prevented from dry burning. Because once the burnt smell is produced, some substances that are not conducive to health will be produced, which wi...

Problems solved by technology

Because once the burnt smell is produced, some substances that are not conducive to health will be produced, which will endanger personal health.

If the e-liquid in the liquid storage component is exhausted but continues to be used, dry burning will occur
