         [0042]    Referring to  FIG. 6  to  FIG. 7 , the connecting head  81  is a hard conductive element, and preferably metallic element. The top electrode  83  is inserted into the connecting head  81 , and an insulating ring  85  is inserted between the top electrode  83  and the connecting head  81  to achieve insulate. The connecting head  81  is substantially hollow column and defines a stepped hole  810 . The inner wall of the stepped hole  810  forms a first inner shoulder  812  and a second inner shoulder  814 . One end of the connecting head  81  being inserted into the slot  73  of the atomizing seat  7  is an inserting end  811 . Corresponding to a depth of the slot  73  of the atomizing seat  7  and the annular flange  71 , the outer wall of the connecting head  81  spaced from the inserting end  811  a predetermined distance forms an outer annular flange  813 . The inserting end  811  is inserted into the slot  73  of the atomizing seat  7  to support the elastic atomizing seat  7 , so as to make the elastic atomizing seat  7  having higher strength. In one embodiment, the outer annular flange  813  may be designed to be stepped shape, and includes a first step  8130  and a second step  8132 . The outer diameter of the first step  8130  is adapted to the inner diameter of the atomizing sleeve  2 , and tightly latches in the connecting end  23  of the atomizing sleeve  2 , and also longitudinally resists a distal end of the annular flange  71  of the atomizing seat  7 . The main body  70  of the atomizing seat  7  is tensioningly inserted into the stepped hole  810  and resists the first inner shoulder  812  so as to further seal and fix the atomizing sleeve  2  and the atomizing seat  7 . The edge of the connecting end  23  of the atomizing sleeve  2  resists on the second step  8132 . The second inner shoulder  814  is in fact a protruding ring formed on the inner wall of the connecting head  81 . The insulating ring  85  is inserted into the stepped hole  810  via another end contrary to the inserting end  811  and latches with the second inner shoulder  814 . The top electrode  83  is inserted into and latches in the insulating ring  85 . The top electrode  83  is long columnar, and forms a flange at a distal end thereof to latch in the insulating ring  85 . The column portion of the top electrode  83  is inserted into and tensioningly fixed the central air channel  74  of the atomizing seat  7  via the connecting head  81  to further support and elastically squeeze the silicon atomizing seat  7 . The side wall of the top electrode  82  and the connecting head  81  correspondingly defines air hole (not labeled), which communicates with the air channel cooperatively defined by the connecting assembly  8 , the atomizing seat  7 , the glass fiber tube  5 , the sealing ring  12  and the inhalation element cover  1  such that the outer air is adsorbed into and adsorbed out with the smoke produced by the atomizing device  10 . 
         [0043]    Referring to the  FIG. 8  showing a semi-finished product, the heating wire  60  is fixed in the glass fiber tube  5 , and the electronic lines  61 ,  63  pass throughout the assembling hole  50  and extend along the outer wall of the glass fiber tube  5 . The two end of the liquid conducting belt (post)  65  passes throughout the assembling hole  50 . At this time, the electronic lines  61 ,  63  respectively passes through the line holes  75 ,  77  of the silicon atomizing seat  7 . The electronic lines  63  passes through the line hole  77  and bend into the inner wall of the central air channel  74  of the atomizing seat  7 . The electronic line  61  passes through line hole  75  and then bends into the slot  73  from the edge of the main body  70 . The inserting end  811  of the connecting head  81  is inserted into the slot  73  of the silicon atomizing seat  7  and tightly latches the electronic lines  61 . The top electrode  83  is inserted in to the central air channel  74  of the atomizing seat  7  and tightly latches the electronic line  63 . The column portion of the top electrode  83  squeezes the silicon atomizing seat  7  from the central air hole  74  of the atomizing seat  7 . Therefore, the electronic lines  63  is pressed between the inner wall of the atomizing seat  7  and the outer wall of the top electrode  83 , thus electrically connected with the top electrode  83 . When the inserting end  811  of the metallic connecting head  81  is inserted into the slot  73  of the atomizing seat  7 , the insert end  811  squeezes the annular flange  71  and the main body  70  of the atomizing seat  7  such that the electronic lines  63  is tightly latched in the slot  73  of the atomizing seat  7  and thus stably electrically connected with the metallic connecting head  81 . After the metallic connecting head  81  and the top electrode  83  is inserted into the atomizing seat  7 , the silicon atomizing seat  7  is elastically pressed inwards to further latch the electronic lines  61 ,  63  passing through the line holes  75 ,  77 , especially latch in the thin necks  750 , 770 . Therefore, the electronic lines  61 ,  63  cannot be pulled. Simultaneously, the annular flange  71  of the silicon atomizing seat  7  is pressed outwards and expands so as to evenly latch in the inner wall of the atomizing sleeve  2 , thus achieve better sealing effect. Furthermore, after the connecting head  81  and the top electrode  83  are inserted into the silicon atomizing seat  7 , the total hardness and strength of the atomizing device is enhanced. Thus, it is convenient to hold the connecting head  81  to package the cloth layer  4  and the liquid storage layer  3  on the glass fiber tube  5 . The liquid storage layer  3  of the embodiment is made of packaging cotton. The assembly is convenient. After packaging the cloth layer  4  and the liquid storage layer  3  on the glass fiber tube  5 , the atomizing sleeve is packaged on the glass fiber tube  5 . Then the inhalation element end  21  is inserted into the sealing ring  12  and the inhalation element cover  1 . Thus the atomizing device  10  is completely assembled.

The outer sleeve  2 ′has a battery cover  103  disposed at the other end thereof contrary to the inhalation element cover  1 . In the disposable electronic cigarette  100 , the positive and negative electrodes of the battery respectively electrically connected with the electronic lies  61 ,  63  of the heating assembly  6 , thus the top electrode  83  may be omitted. 
         [0046]    Referring also to  FIG. 10 , the inhalation element cover  1  and the sealing ring  12  are latched each other, and an extending portion  13 ′ inserting into the glass fiber tube  5  may be designed to axially extend from the inhalation element cover  1 .
