The second insulating sleeve  621  has an opened end opposing its top wall, and defines a second pole hole (not labeled) in the top wall for protrusion of the second pole  622 .

In this embodiment, the first seat  51  entirely serves as the first magnetically-attracted portion. The second seat  61  entirely or partially forms a second magnetically-attracted portion for magnetically attracting the first magnetically-attracted portion. In order to facilitate better positioning and fixing when the second seat  61  of the connector is mated with the first seat  51  of the atomizer, the first seat  51  is capable of being made of a conductive magnet or magnetic material, and the magnetic material may be an iron material, so that the first seat  51  constitutes the first magnetically-attracted portion, instead, the first seat  51  can also be configured with an independent component made of a conductive magnet or magnetic material that servers as the first magnetically-attracted portion; or part of the first magnetically-attracted portion is made of a conductive material. Correspondingly, the second seat  61  is also capable of being made of a conductive magnet or magnetic material, so that the second connecting seat  61  entirely constitutes the second magnet for magnetically attracting the first magnetically-attracted portion of the first seat  51 , instead, the second seat  51  can also be configured with an independent component made of a conductive magnet or magnetic material that servers as the second magnetically-attracted portion, or the second magnetically-attracted portion is partially constituted by a conductive material. In this embodiment, the permanent magnet  922  independently constituted by magnet or magnetic material is used as the second magnetically-attracted portion. Therefore, the matching relationship between the first magnetically-attracted portion and the second magnetically-attracted portion can be magnet and magnet, magnet and magnetic material, or magnetic material and magnet. 
         [0042]    As shown in  FIG. 3 , when the first connecting mechanism  5  of the atomizer  91  is inserted into the connecting casing  921  of the connector  92  to the right place, the first seat  51  has its one end to abut against or be close to the permanent magnet  922  of the second connecting mechanism  6 . Because of the magnetic force of the permanent magnet  922 , the first seat  51  is firmly attracted by the permanent magnet  922  but cannot be easily detached from the connector  91 , the second pole  622  of the second connecting mechanism  6  is slightly retracted for it is abutted against by an end face of the first pole  52  of the first connecting mechanism  5  to overcome the elastic force of the spring  624 , to ensure the first pole  52  and the second pole  622  in good contact with each other; moreover, the side wall of the first seat  51  and the inner wall of the connecting casing  921  circumferentially contact with each other to realize conduction therebetween, to thereby achieve corresponding conduction of inner circuits of the atomizer  91  and the connector  92 . 
         [0043]    As shown in  FIG. 8 , the power rod  95  is substantially tubular-shaped, and its end connected with the connector  92  is configured with an inner thread joint  951  mating with the outer thread joint, the inner thread joint  951  is configured with a lower pole  952  therein to abut against the upper pole  623  for conduction, and the lower pole  952  is fixed in the inner thread joint  951  by means of an insulating sleeve  953 ; the lower pole  952  defines a vent coaxially extended therethrough. The inner thread joint  951  and the lower pole  951  respectively serve as a first electrode and a second electrode of the power rod  95 . The power rod  95  is configured with a storage battery  955  and so on. The storage battery  955  has its first electrode and second electrode to be respectively electrically connected with the inner thread joint  951  and the lower pole  952 . The power rod  95  has its another end configured with an end cap  956 , and the end cap  956  is configured with an indicator light and intake holes (not shown). 
         [0044]    Additionally, as shown in  FIG. 3 , external air enters the power rod  95  via the intake holes of end cap  956  which disposed at a bottom of the power rod, and goes into the second insulating sleeve  621  after passes by the lower pole  952  and the vent of the upper pole  623 , and then enters the atomizer  91  in turn through the vents of the second pole  622  and the first pole  52 , and then passes by the vent of the atomizing holder  213  and the vent of the sucking cylinder  1 , finally flows out of the sucking rod  90  via the vent of the nozzle cover  4 . Summarily, there is a special airflow channel defined inside of the electronic cigarette, which achieves smooth air circulation inside and outside of the electronic cigarette. Certainly, external air can also enter the atomizer  91  directly via the vent of the nozzle cover  4 .
