Electronic cigarette ignition device and control method thereof

Abstract

The invention discloses an electronic cigarette ignition device and a control method thereof and belongs to the technical field of electronic cigarettes. The electronic cigarette ignition device comprises an MIC, a data acquisition unit, a control unit and a signal regulation unit, wherein the MIC is used for detecting gas flow so as to acquire gas flow sound signals; the data acquisition unit isused for sampling the gas flow sound signals so as to acquire corresponding digital audio detection signals; the control unit is used for analyzing the digital audio detection signals and outputting an ignition start-up control signal or ignition turn-off control signal, or issuing a signal regulation instruction or regulating a first ignition threshold value according to pre-set control logics and the first ignition threshold value; the signal regulation unit is used for regulating the gas flow sound signals according to the signal regulation instruction. According to the electronic cigaretteignition device and the control method thereof, the amplitude of gas flow sound signals output from the MIC can be regulated, so that the electronic cigarette ignition device can adapt to various performance parameters of the MIC, the customization cost of the MIC is reduced, the waiting supply time during MIC customization is saved, and thus, the production efficiency is increased; furthermore,the gas flow strength of electronic cigarette ignition can be flexibly changed.

Description

technical field [0001] The present invention relates to the technical field of electronic cigarettes, in particular, to an electronic cigarette ignition device and a control method thereof which utilize a microphone (abbreviated as MIC) to detect air flow. Background technique [0002] Electronic cigarette is a kind of virtual cigarette, its appearance is similar to that of ordinary cigarettes, and it can produce a taste similar to that of cigarettes. It is mainly used for smoking cessation and replacement of cigarettes. Electronic cigarettes usually consist of a power supply, a cigarette rod, a cartridge, an atomizer and a controller. The power supply is set in the cigarette rod, the atomizer is equipped with a heating wire, the atomizer is set in the pod, the pod guides the nicotine or nicotine substitute solution into the atomizer, and the controller controls the power supply and the atomizer When the heating wire in the atomizer is working, it heats the atomizer and tur...

Problems solved by technology

[0006] The MICs produced by different manufacturers are different. For example, for capacitive MICs, various parameters such as the type of metal sheet, the area of ​​​​the metal sheet and its distance may be different, which leads to great differences in the electrical signals output by various MICs.

[0007] The parameters of each component of the hardware logic circuit in the MIC circuit of the electronic cigarette ignition controller need to work in harmony with the electrical signal output by the MIC. In order to be able to coordinate with the parameters of each component of the hardware logic circuit, in the prior art, Can only use a certain kind of MIC, even need to customize MIC

[0008] In addition, in the prior art, once the ignition threshold in the controller is set, it cannot be changed, and it cannot be flexibly set according to the user's environment.
