Abstract

The invention discloses an electronic cigarette circuit and an electronic cigarette. The electronic cigarette circuit comprises a capacitance-type microphone and an air flow detecting chip, wherein the capacitance-type microphone is configured to sense the air flow intensity, and output a corresponding air flow intensity signal according to the air flow intensity; the input end of the air flow detecting chip is connected with the output end of the capacitance-type microphone; and the air flow detecting chip is configured to provide work current for the capacitance-type microphone, and output apulse density modulation signal with the corresponding density according to the air flow intensity signal. With the technical scheme, the inhaling time and the air flow intensity generated during inhaling of a user can be detected.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an electronic cigarette circuit and the electronic cigarette. Background technique [0002] E-cigarettes simulate traditional cigarettes smoked by users by using a heating circuit to heat and atomize e-liquid with a tobacco smell. At present, electronic cigarettes have been more and more widely used. The working principle of the existing electronic cigarette is: when the airflow sensor in the electronic cigarette senses the user’s inhalation, it will continuously trigger the airflow sensor switch to turn on the heating circuit in the electronic cigarette for the duration of the user’s inhalation, and the heating circuit will be turned on Afterwards, the smoke oil is atomized. However, the existing electronic cigarettes can only trigger the air flow sensor switch to connect the heating circuit in the electronic cigarette according to the length of the user's inhalati...
