When the user does not perform a suction action, the air pressure inside the atomizer 1 is the same as the outside air pressure, and the air pressure in the air inlet channel 4 communicating with the inside of the atomizer 1 is also the same as the outside air pressure, and the airflow in the starting air channel 5 is constant. , the airflow sensor 22 controls the battery assembly 21 not to supply power to the atomizing core 11 in the atomizer 1, and the atomizing core 11 does not heat and atomize the substrate to be atomized. In this way, the user can avoid the waste of the substrate to be atomized and electric resources caused by heating and atomizing the substrate to be atomized by the atomizing core 11 when the user does not need to suck.

In the electronic atomization device provided in this embodiment, the battery device can provide electrical energy to the atomizer to make the atomizer heat and atomize the substrate to be atomized. The battery device includes: a casing, and the casing is provided with a container The accommodating cavity is used for accommodating the atomizer, and the accommodating cavity is provided with an air inlet channel, and the air inlet channel is arranged between the inner wall of the accommodating cavity and the accommodating atomizer; The air inlet is connected to the air inlet channel, and the other end is connected to the air flow sensor; the air flow sensor is used to sense the air flow and control the battery assembly to supply power to the atomizer; wherein, the air inlet is higher than the bottom of the accommodating cavity, so that the air intake The airflow of the channel passes through the air inlet. In the electronic atomization device provided by the present application, by connecting the air inlet channel with the air inlet of the start air channel, the air inlet of the start air channel is higher than the bottom of the atomizer, so as to avoid condensation of the substrate to be atomized for use in the atomizer. Gravity flows to the starting air passage, thereby avoiding the accumulation of condensate and blocking the starting air passage, keeping the starting air passage clean, preventing condensate from damaging the airflow sensor, and prolonging the service life of the electronic atomization device.
