The present application relates to a technical field of an electronic cigarette, and more particularly relates to an electronic cigarette and an atomization control method thereof.
In the prior art, electronic cigarettes generally comprise two parts which are an atomization assembly for atomizing e-liquid and a battery assembly for supplying power to the atomization assembly. Among them, an existing electronic cigarette integrated an airflow sensor with a control circuit to control the electronic cigarette, when the user smoking electronic cigarette, the electronic cigarette air pressure will change, resulting in deformation of a thin film capacitor of the airflow sensor. When the amount of the deformation of the thin film capacitor reaches a threshold, a trigger signal is sent to the microprocessor in the control circuit to ensure the microprocessor to control the battery assembly to supply power to the atomization assembly to atomize e-liquid.
However, such an electronic cigarette in a packaging or transport process, is prone to cause a change of the air pressure in the electronic cigarette, which causes the electronic cigarette to work automatically.

(1) The first conductor is provided on the outer peripheral surface of the battery assembly, and the outer peripheral surface of the suction nozzle is provided with a second conductor, when smoking, the user directly holds on the first conductive sleeve by fingers, a mouth is held on the suction nozzle, so as to realize contacts between the conductive sleeves at different positions on the outer surface of the electronic cigarette and the user skin at the same time, and to transmit the conduction signal to the control module so that the control module controls the power source to supply the heating wire assembly to atomize the e-liquid and starts the electronic cigarette working.
Therefore, the present invention can reduce a probability that the electronic cigarette is mistakenly triggered, effectively solves the problem in the prior art that the electronic cigarette works when the key switch, the touch switch or the airflow sensor is often mistakenly triggered, resulting in a change of deterioration of taste of the e-liquid of the electronic cigarette caused by repeated oxidization and, a short electronic cigarette life, low safety and other issues. Moreover, by providing the structure of the present invention, it is possible to reduce conditions of the packaging apparatus for transporting the electronic cigarette, thus to facilitate the transportation and the transportation is more secure. In addition, during a using process, the structure meets user requirements that the user can smoke when the fingers are held on the battery assembly and the mouth is held on the suction nozzle, it is more user-friendly, improves user experience, so as to avoid a complex using problem that the touch keys or switches are needed in the prior art, and to avoid the problem that the airflow sensor cannot detect the smoke signal when the smoking force is small, the e-liquid enters the battery assembly from the airflow channel, and other problems.
(2) Since the atomization assembly is detachably connected to the battery assembly, it is convenient for the user to replace the atomization assembly after that the atomization assembly is damaged.
While the embodiments of the present application are described with reference to the accompanying drawings above, the present application is not limited to the above-mentioned specific implementations. In fact, the above-mentioned specific implementations are intended to be exemplary not to be limiting. In the inspiration of the present application, those ordinary skills in the art can also make many modifications without breaking away from the subject of the present application and the protection scope of the claims. All these modifications belong to the protection of the present application.
