In addition, the electronic cigarette is atomized through tobacco tar, the solution containing the tobacco tar and essence is atomized into particles, the particles are absorbed through the lung, and meanwhile simulated smoke is discharged, tar and other harmful ingredients in the cigarette are not contained, no second-hand smoke is generated, and no second-hand smoke is generated or is trapped in a closed space, so that more and more people use the electronic cigarette to replace the traditional cigarette.
The atomization device in the prior art generally controls the on/off of the electronic cigarette by arranging a sensor in an airflow channel close to an air inlet to detect the suction action of a user, however, the atomization device in the prior art has at least one of the following problems, the first is that the sensitivity of the sensor in the prior art is not high, and the user needs to suck with relatively great force, so that the airflow in the airflow channel flows to cause the change of the air pressure, and the sensor can detect the change. Second, because the piece that generates heat is located airflow channel and the sensor is located between piece and the inlet port that generates heat among the prior art for user's suction can receive the hindrance of the piece that generates heat, and user's suction can be tired. Thirdly, the atomization device in the prior art can only generate airflow by adopting a suction mode, and cannot automatically generate airflow, so that the application range is limited.
