`in the lower passage; the upper passage is adapted to the lower
`section 512 of the first seat 51 for the first seat 51 being
`inserted. A fixed flange 614 radially extends outwards from an
`end sidewall of the second connector 6, and the fixed flange
`614 radially defines a thorough air inlet 615.
`[0043] As shown in FIGS. 4 to 6, the second terminal
`assembly 62 comprises an insulation base 620, a second
`terminal post 622 disposed in center of the base 620, a spring
`624 fitted around the second terminal post 622 and a second
`insulation sleeve 624 disposed between the insulation base
`620 and the second terminal post 622. The insulation base
`620, the second terminal post 622, the second insulation
`sleeve 624 and the spring 626 constitute the second terminal
`assembly 62, are assembled as a whole, which facilitates
`assembly and disassembly of the electronic cigarette conve(cid:173)
`niently, and make the assembly and disassembly of the elec(cid:173)
`tronic cigarette simply and quickly.
`[0044] The insulation base 620 is shaped about a cup, is
`made from insulate materials, comprises a sidewall 6201, a
`bottom wall 6202 and a protruding bar 6203 longitudinally
`extending outsides from the bottom wall 6202 so as to facili(cid:173)
`tate soldering; the sidewall 6201 and the bottom wall 6202
`enclose an inner cavity 6204 for accommodating the second
`terminal post 622, the bottom wall 6202 further defines a first
`terminal hole 6205 for passing the second terminal post 622.
`The second terminal post 622 is inserted in the second insu(cid:173)
`lation sleeve 624, one end thereof extending outwards for
`coupling a corresponding terminal post of external connector,
`another end of the second terminal post 622 within the insu(cid:173)
`lation base 620 is set with a stop flange 6220, and the spring
`626 is fitted around the end of the second terminal post 622
`within the insulation base 620, both ends of the spring 626
`respectively abuts against the stop flange 6220 and the bottom
`wall of the insulation base 620, and the spring 626 keeps the
`second terminal post 622 extending outwards. The second
`insulation sleeve 624 is also shaped about a cup, comprises a
`sidewall 6241, bottom wall 6242, and a flange 6243 radially
`extending outwards from the sidewall 6241, and a guiding
`part 6244 axially extending from the bottom wall 6243, the
`sidewall 6241 and the bottom wall 6242 enclose an inner
`cavity 6245 for accommodating the second terminal post 622,
`the guiding part 6244 further defines a second terminal hole
`6246 axially through center of the guiding part 6244 and
`communicating with the inner cavity 6245. The second insu(cid:173)
`lation sleeve 624 is mounted with interference fit in the inner
`wall of the first inner cavity 6204 of the insulation base 620
`via the sidewall of the body 6241 and is axially fixed via the
`flange 6243 abutting against an open end of the first inner
`cavity 6204 of the insulation base 620. One end of the second
`terminal post 622 passes the second terminal hole 6246 and
`extends outside of the guiding part 6244, the stop flange 6220
`of the second terminal post 622 keeps abutting against the
`bottom wall 6242 of the second insulation sleeve because of
`the force of the spring 626, and another end of the second
`terminal post 622 passes the first terminal hole 6205 and
`extends outside of the bottom wall of the insulation base 620.
`[0045] As shown in FIG. 4, the permanent magnet 63 has an
`annular structure, the permanent magnet 63 is hollow in cen(cid:173)
`ter (not labeled) for passing the second terminal post 622
`therethrough, and the permanent 63 is fixed in the second
`connector 6.
`[0046] The first seat 5 wholly or partly forms a first mag(cid:173)
`netic absorption part, and in this embodiment, the first seat 5
`wholly forms the first magnetic absorption part. The second
`
`seat 61 wholly or partly forms a second magnetic absorption
`part which may magnetically attract the first magnetic
`absorption part. For better position and fixing when the sec(cid:173)
`ond seat 61 of the power shell 91 couple to the first seat 51 of
`the inhaling shell 90, the first seat 51 may be made from
`conductive magnetic materials or magnetic iron, the magnetic
`materials may be iron materials; therefore, the first seat 51
`forms the first magnetic absorption part, otherwise, the first
`seat 51 can be set with an independent component made from
`conductive magnetic materials or magnetic iron as the first
`magnetic absorption part; or a part of the first magnetic
`absorption part is made from conductive materials. Accord(cid:173)
`ingly, the second seat 61 may be made from conductive mag(cid:173)
`netic materials or magnetic iron, thus the second seat 61
`wholly forms the second magnetic absorption part which
`attracts the first magnetic absorption part of the first seat 51;
`or the second seat 61 can be set with an independent compo(cid:173)
`nent made from conductive magnetic materials or magnetic
`iron as the second magnetic absorption part; or a part of the
`second magnetic absorption part is made from conductive
`materials. In this embodiment, the permanent magnet 63 is
`used as the second magnetic absorption part which is inde(cid:173)
`pendently configured and is made from magnet or magnetic
`materials. Therefore, a relation between the first magnetic
`absorption part and the second magnetic absorption part may
`be such relation between a magnetic iron and a magnetic iron,
`between a magnetic iron and a magnetic material, or between
`a magnetic material and a magnetic iron.
`[0047] As shown in FIG. 2, until the first connector 5 of the
`inhaling shell 90 is inserted in place into the second connector
`6 of the power shell 91, herein, the lower section 512 of the
`first seat 51 is inserted in the air passage 611 of the second seat
`61, while the second terminal post 622 of the second connec(cid:173)
`tor 6 is pushed by an end of the first terminal post 53 of the first
`connector 5 to overcome the resilience force of the spring 626
`and slightly retract, and thus tightly abuts against the first
`terminal post 53 under the force of the spring 626, which
`ensures a good contact between the first terminal post 53 and
`the second terminal post 622; furthermore, the lower section
`512 of the first seat 5 is spaced to and not abut against the
`permanent magnet 63, which ensures the first connector 5 and
`the second connector 6 to closely attract each other, ensures
`electric circuit switched and that the inhaling shell 90 and the
`power shell 91 are attracted and connected with each other
`without any gap, and then ensures a good contact between the
`first connector 5 and the second connector 6, thus the electric
`circuits of the inhaling shell 90 and the power shell 91 are
`intercommunicated, as for the appearance, no gap existing
`between the inhaling shell 90 and the power shell 91 makes
`the electronic cigarette more aesthetic.
`[0048] As shown in FIGS. 2 to 4, air in external environ(cid:173)
`ment enters into the power shell 91 from the air inlet port 261
`in the end cover 26 at the bottom of the power shell, passes
`through hollow center of the second terminal post 622 and the
`hollow center of the first terminal post 53 and enters into the
`inhaling shell 90; or, air in external environment enters into
`the inhaling shell 90 from the air in
