In this embodiment, an insulation part  90  is arranged between the inner electrode  80  and the battery  40  to effectively prevent the short circuit problem. 
         [0036]    Specifically, as shown in  FIG. 4  and  FIG. 5  with referring to  FIG. 3 , the fixed support  50  which is provided in the preferred embodiment of the present invention presents a cylindrical structure with an end opening and the other end closing. The fixed support  50  comprises an inserting part  502  connected to the outer electrode  70  and an extending part  501  which is formed by extending from an end surface of the close end of the inserting part  502  toward the battery  40 .

A radian of the extending part  501  can be same as a radian of the inserting part  502 , so a manufacturing process of the extending part  501  is easy and the processing costs can be saved. The extending part  501  is used for forming an interval between the inner electrode  80  and the battery  40 . The insulation ring  60  is arranged on an exterior of the inner electrode  80  and covers the opening end of the fixed support  50 . Thus the inner electrode  80  can be mounted more securely. 
         [0037]    In order to prevent a short circuit between the inner electrode  80  and the battery  40 , an insulation part  90  is arranged between the inner electrode  80  and the battery  40 .

The obstructing part  902  extends along a direction which is vertical to the connecting part  901  to an outer side of the inner electrode  80 . Thus the inner electrode  80  and the battery  40  can be isolated. 
         [0039]    In this embodiment, a thickness of the joint of the connecting part  901  and the edge of the end of the fixed support  50  is smaller than a thickness of the connecting part  901  and the inserting part  502 . Thus the connecting part  901  can be folded around the joint. The insulation part  90  that can be folded can make the insulation part  90  more flexible to be better matched with the fixed support  50 , a structure of the whole insulation part  90  can be applied wider. It can be understood that, in other embodiments, the connection part  901  and the inserting part  502  of the fixed support  50  can be movably connected by a pivot connection or a hinged connection. In this embodiment, when the insulation part  90  is needed to be used, the insulation part  90  can be folded to a location between the inner electrode  80  and the battery  40  to isolate them. 
         [0040]    In order to stably place the insulation part  90  after being folded between the inner electrode  80  and the battery  40 , a fastener  904  is arranged on the insulation part  90 . The insulation part  90  is fixed on the fixed support  50  by the fastener  904 . Specifically, as shown in  FIG. 4 , a joint of the connecting part  901  of the insulation part  90  and the obstructing part  902  is provided with an avoiding groove  903  which is a strip. The purpose of arranging the avoiding groove  903  is to better connect the fixed support  50  of the insulation part  90  to extending part  501 . The avoiding groove  903  extends from the connecting part  901  to the obstructing part  902 . An end of the avoiding groove  903  where the obstructing part  902  locates is provided with the fastener  904  which is used for fastening the fixed support  50 . The fastener  904  is a bulge which is formed by extruding along a side of the obstructing part  902  near the fixed support  50  toward the fixed support  50 . The longitudinal section of the bulge can be a semicircular or a trapezoid. In this embodiment, the fastener  904  is fastened with a groove of an edge of the extending part  501  of the fixed support  50 . So the insulation part  90  that can be folded is fixed on the fixed support  50 . The insulation part  90  is fixed on the fixed support  50  by the fastener  904 . It is easy to assemble and a production efficiency can be improved. 
         [0041]    The electrode component provided in the other embodiment of the present invention is shown in  FIG. 6  and  FIG. 7 . The only difference of the electrode component provided in this embodiment with the electrode component provided in the previous embodiment is the structure of the insulation part  90 . In this embodiment, the insulation part  90  comprises an isolating part (not labeled) which is connected to an edge of an end of the extending part  501  which is along an axial direction of the extending part  501 , the isolating part is used for isolating the inner electrode  80  from the battery  40 . In this embodiment, the insulation part  90  comprises a first isolating part  905  which covers the inner electrode  80  and presents a disc shape, and a second isolating part  906  which is perpendicularly connected to the first isolating part  905 . The second isolating part  906  is form by extending from an edge of the isolating part  905  towards a side of the fixed support  50 , an end of the second isolating part  906  abuts against a surface of the close end of the inserting part  502 . Thus, the first isolating part  905 , the second isolating part  906  and the extending part  501  surround a close space which is used for accommodating a part of the inner electrode  80  which extends outside the through hole, then the inner electrode  80  and the battery  40  are completely isolated. In order to realize an electrical connection of the controller  30  and the inner electrode  80  by wires connection, a breach  907  is arranged at the first isolating part  905 . The breach is used for being through by wires to connect the inner electrode  80 . 
         [0042]    In this embodiment, in order to make the insulation part  90  and the fixed support  50  movably connected, an elastic piece  100  is defined to realize a connection between the insulation part  90  and the fixed support  50 . An end of the elastic piece  100  is connected to the first isolating part  905 , the other end of the elastic piece  100  is connected to the extending part  501 , so the insulation part  90  can be folded around the elastic piece  100  and a force required for folding is not large. Thus, the insulation part  90  that can be folded can make the insulation part  90  more flexible and be better matched with the fixed support  50 . The structure of the whole insulation part  90  can be applied wider. In order to increase the stability of the folding, a pair of elastic pieces  100  are connected between the first isolating part  905  and the extending part  501  in this embodiment. 
         [0043]    The battery stick provided in the present invention can effectively prevent the short circuit problem between the battery electrodes and the inner electrode by arranging an insulation part between the battery and the inner electrode. Further, the insulation part can be folded to make it more flexible and can be better matched with the fixed support, then the assembly of the electronic cigarette is more convenient.
