First Embodiment
Referring to FIG. 2, a battery assembly 101 of an electronic cigarette according to an embodiment of the present application is configured to form an electronic cigarette in combination with an atomizing assembly 102. The atomizing assembly 102 is provided with a substance to be detected, and the battery assembly 101 includes a spectrum identification device 103 and a microcontroller 104.
The spectrum identification device is arranged on the battery assembly and configured to obtain spectrum information of the substance to be detected.

In addition, the present application also avoids a poor user experience resulting from the mixed use of the existing battery assembly and atomizing assembly in any combination, the mixed use of cigarette liquids having different flavors, and the mixed use of the battery assembly and the atomizing assembly from different manufacturers.
Preferably, as shown in FIG. 3, in this embodiment, the spectrum identification device may further include a light emitting module 1031 and a light receiving and converting module 1032. The light emitting module is connected with the microcontroller and configured to generate light with a preset wavelength to irradiate the substance to be detected. The light receiving and converting module is configured to receive second light formed by irradiating the substance to be detected with the light having the preset wavelength, and convert the second light to an electrical signal and output the electrical signal to the microprocessor. The second light may include diffracted light and transmitted light.
This embodiment further provides a circuit structure of the light emitting module and the light receiving module. Referring to FIG. 4, the light emitting module is an infrared light emitting module, and the infrared light emitting module includes an infrared light source 10311, a parabolic reflector 10312, a digital frequency synthesizer 10313, a radio frequency driver 10314 and an acousto-optic tunable filter 10315.
The infrared light source 10311 emits infrared light. The parabolic reflector 10312 is configured to reflect the infrared light to obtain reflected light. The digital frequency synthesizer 10313 is connected with the microcontroller 104 and is configured to perform frequency processing on a control signal sent from the microcontroller 104 to generate a first signal. The radio frequency driver 10314 is connected with the digital frequency synthesizer 10313 and is configured to perform low pass filtering and power amplification on the first signal to generate a second signal. The acousto-optic tunable filter 10315 is connected with the radio frequency driver 10314 and is configured to process the reflected light according to the second control signal to generate the light with the preset wavelength and transmit the light with the preset wavelength to the substance to be detected.
It should be noted that, the radio frequency driver 10314 may include a low pass filter circuit, an amplification circuit and a power amplification circuit. The low pass filter circuit is connected with the digital frequency synthesizer 10313. The amplification circuit is connected with the low pass filter circuit and is configured to amplify an output signal of the low pass filter circuit.

The low pass filter circuit 10325 is connected with the detection circuit 10324 and is configured to perform filtering on an output signal of the detection circuit 10324. The analog to digital conversion circuit 10326 is connected with the low pass filter circuit 10325 and is configured to perform analog to digital conversion on an output signal of the low pass filter circuit 10325.
The working principle of the spectrum identification device is briefly described hereinafter in conjunction with the above connection relationship. The detection is performed based on the fact that each substance has a specific spectrum absorption characteristic, i.e., different gases have different molecular or atomic structures, thus have different characteristic absorption wavelengths. Then an absorption peak of the substance at a specific wavelength and a wavelength value at the characteristic peak are determined based on the spectrum, and then whether the spectrum of the substance to be detected is the spectrum of the preset substance is determined. In a case that the controller determines that the detected spectrum does not match the preset spectrum, the controller controls the circuit between the battery assembly and the atomizing assembly to be switched off to power off the electronic cigarette, thereby efficiently avoids the problem that damages on the electronic cigarette, for example battery overheat or battery leakage, are caused in a case that the battery assembly and the atomizing assembly, which are not matched, are used in combination.
