The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
In one embodiment, as shown in fig. 1, there is provided an electronic atomizer comprising:
a liquid storage chamber 100 for storing tobacco tar;

and the processing unit 400 is used for determining the smoke content state of the liquid storage cavity 100 according to the detection electric signal output by the resonance unit 300.
In an alternating current circuit comprising a resistor, an inductor and a capacitor, the voltage at two ends of a resonant coil (inductor) L and a resonant capacitor C in the circuit is generally out of phase with the current in the loop, if the circuit parameters or the power frequency are adjusted to make the current and the power voltage in the same phase, the circuit is resistive, and the working state of the circuit at this moment is called resonance. The resonance phenomenon is a specific phenomenon of a sinusoidal alternating current circuit, and is widely applied to electronic and communication engineering, and the resonance is generally divided into series resonance and parallel resonance. The series resonance is a resonance occurring in a circuit in which the resonance coil L and the resonance capacitor C are connected in series. The parallel resonance is a resonance occurring in a circuit in which the resonance coil L and the resonance capacitor C are connected in parallel. When the circuit is in series resonance, the total impedance in the circuit is minimum, and at a certain voltage, the current reaches the maximum value. The total impedance in the circuit is at a maximum when the circuit is in parallel resonance and the current will reach a minimum at a constant voltage.
When having the tobacco tar in stock solution chamber 100, because the tobacco tar has electrically conductive composition, will lead to resonance unit detuning, resonance unit's complex impedance changes, and resonance unit output detection electrical signal (current signal or voltage signal) is different with the electrical signal when resonance unit takes place under the no tobacco tar state of stock solution intracavity this moment, consequently according to resonance unit output the detection electrical signal with can judge the tobacco tar content state of stock solution intracavity.

In an embodiment, the detection electrical signal (which may be a current signal or a voltage signal) output by the resonance unit at this time may also be compared with a preset current or voltage when the resonance unit resonates in the full-tobacco-tar state, and the closer to the preset current or voltage, the more the content of the tobacco tar is, and the state of the content of the tobacco tar is known.

Comparing the detection electric signal (which may be a current signal or a voltage signal) output by the resonance unit with a preset current or voltage when the resonance unit resonates in the oil-free state, wherein the closer the detection electric signal is to the preset current or voltage, the lower the content of the tobacco tar is, and if the detection electric signal is equal to the preset current or voltage, the lower the content of the tobacco tar is, the no tobacco tar is in the liquid storage cavity. In one embodiment, the excitation source may further output an excitation signal for causing the resonance unit to resonate in a full-tobacco-tar state, and the detection electrical signal (which may be a current signal or a voltage signal) output by the resonance unit is compared with a preset current or voltage for causing the resonance unit to resonate in the full-tobacco-tar state, and the closer to the preset current or voltage, the more the content of the tobacco tar is, and the state of the content of the tobacco tar is known.
