positive electrode of the battery , the other end of the resistor r 11 is grounded , and a positive input terminal of the comparator u 3 receives a filtered conductive signal and compares the filtered conductive signal with a reference voltage signal of the reverse input terminal , and an output terminal of the comparator u 3 circuit outputs a comparison result signal as a trigger signal to the microprocessor 532 . fig7 and 8 show an electronic cigarette provided in the second embodiment of the present invention , the second embodiment differs from the first embodiment in that the structure of the atomization core 4 is different . as shown in fig7 , the fixing block 43 is substantially a ring - shaped structure which is embedded and fixed to an inner side wall of the first base body 411 close to one end of the suction nozzle 2 . as shown in fig8 , the fixing block 43 is a silicone member , an elastic piece ( not labeled in figures ) is defined on the fixing block 3 , the elastic piece has at least one elastic conductive arm 431 extending into the smoke passage of the atomization seat 41 , the vent pipe 32 is inserted in the smoke passage , and the elastic conductive arm 431 is resiliently abutted against and electrically connected to a sidewall of the vent pipe 32 . the present embodiment arranges the fixing block 43 and the elastic piece structure independently from each other , and is actually more reasonable in practice , and the elastic piece structure has a plurality of elastic conductive arms 431 , and by increasing the number of the elastic conductive arms 431 , stability of electrical connections between the elastic conductive arms 431 and the vent pipe 32 is increased to prevent a contact between the elastic conductive arms 431 and the vent pipe 32 from being poor . further , one elastic conductive arm 431 is electrically connected to the atomization electrode assembly 46 , and as shown in fig8 , the elastic conductive arm 431 is provided with a perforation 432 through which an electric wire ( not labeled in figures ) passes , one end of the electric wire is connected to the elastic conductive arm 431 and the other end of the electric wire is connected to the atomization electrode assembly 46 so that the elastic conductive arm 431 is electrically connected to the atomization electrode assembly 46 . since the elastic conductive arm 431 is electrically connected to the vent pipe 32 and the suction nozzle 2 , then the atomization electrode assembly 46 is electrically connected to the vent pipe 32 and the suction nozzle 2 . it is to be understood that the above - described connection between the atomization assembly 1 and the battery assembly 2 is a detachably connection , and certainly , the structure of the battery assembly 2 and the atomization assembly 1 may be an in - detachable and integrated structure , namely , the electronic cigarette may be a disposable electronic cigarette , or other electronic cigarettes capable of repeatedly adding e - liquid to be repeatedly used , and the structure thereof is not particularly limited thereto . the present invention further provides an atomization control method of an electronic cigarette , the electronic cigarette is the above electronic cigarette , the atomization control method of an electronic cigarette comprises following steps : s1 . conducting the first conductor 51 and the second conductor 21 by user &# 39 ; s skin when the user contacts the first conductive sleeve and the second conductor 21 through the skin simultaneously , so as to generate a conduction signal to the control module 53 ; s2 . controlling the power source to supply the electrical power to the heating wire assembly 42 to atomize e - liquid when the control module 53 receives the conduction signal and a smoking signal , the conduction signal is generated by that the first conductor 51 and the second conductor 21 are conducted . in general , the electronic cigarette and an atomization control method thereof of the present invention has following advantageous effects : ( 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 .
