`
`TECHNICAL FIELD
`
`[0001] This invention relates to a field of electronic ciga(cid:173)
`rettes, and particularly to an electronic cigarette which is
`ultra-long and transparent.
`
`DESCRIPTION OF BACKGROUND
`
`[0002] A current electronic cigarette sucking rod com(cid:173)
`prises: an opaque sucking cylinder, a liquid smoke compart(cid:173)
`ment disposed in the sucking cylinder and integrated with the
`sucking cylinder, an inhaling passage, an atomizing device
`disposed in the sucking cylinder and having a heating wire
`and an atomizing cup, an elongated tubular liquid conduit for
`guiding the liquid smoke to flow into the atomizing device, a
`nozzle cover disposed at an end of the sucking cylinder, and
`an inhaling passage for transmitting the liquid smoke in the
`atomizing cup to an exterior of the sucking cylinder via the
`nozzle cover. One end of the liquid conduit is inserted into the
`liquid smoke compartment, another end of the liquid conduit
`is inserted into the atomizing device, and the liquid smoke is
`guided to the atomizing device through the liquid conduit.
`The heating wire is welded to the positive electrode and the
`negative electrode respectively by riveting technology of
`bonding wire or copper tube.
`[0003] Existing electronic cigarettes have the following
`shortcomings: since the liquid conduit is inserted into the
`liquid smoke compartment, it is complex and inconvenient to
`be installed, and easy to lead to leakage, and the fluid amount
`is also not easy to control. Secondly, the heating wire is
`welded or riveted to the conductive wire in advance before it
`is welded to the copper electrodes of the atomizer, the process
`is more complicated, and the installation is not easy. The
`inhaling passage is disposed at a side of the liquid smoke
`compartment and vents at the side, this would adversely affect
`the liquid reserving volume of the liquid smoke compartment
`in a predetermined volume, and decrease the liquid reserving
`volume of the liquid smoke compartment. The liquid smoke
`compartment and the inhaling passage and the sucking cyl(cid:173)
`inder are integrally formed, thus the length of the electronic
`cigarette sucking rod is fixed. Additionally, the existing atom(cid:173)
`izing cup is constructed by several components, which is not
`convenient to install the heating wire. The sucking cylinder is
`opaque, and the liquid smoke volume in the liquid smoke
`compartment cannot be observed, it would cause empty to
`bum of the heating wire and generate odor gas after the liquid
`smoke has run out.

`after bent again. Said one end of the heating wire is tightly
`clamped between an inner wall of the first electrode member
`13 and an outer wall of the atomizing cup 22 by mutual
`expansion of the atomizing cup 22 and the first electrode
`member 13 to get the electrical connection with the first
`electrode member 13. Another end of the heating wire 211
`passes through another perforation hole 223 and is electri(cid:173)
`cally connected with the electrode member 14, and is tightly
`clamped between an outer wall of the electrode member 14
`and an inner wall of the insulating ring 15 by mutual expan(cid:173)
`sion of the insulating ring 15 and the electrode member 14.
`The method of clamp realizes the electrical connection by
`simple process, and it is easy for installation without the use
`of welding. The heat dissipating hole 224 is for ventilation
`and allows the heat generated y the atomizer 21 to be trans(cid:173)
`ferred to the power rod 91. A lower end of the atomizing
`device 22 and an inner wall of the second end 132 of the first
`electrode member 13 are mutually engaged to tighten the
`heating wire 211. In the embodiment, the atomizing cup 22
`adopts a material having good heat resistant, such as silicone
`material, to gain better heat insulation effect of the atomizing
`cup 22. The atomizing cup 22 of the embodiment simplifies
`the fabrication process of the electronic cigarette sucking rod,
`and also facilitates the installation of the atomizer 21. Fur(cid:173)
`thermore, since the atomizing cup 22 is made of silicone
`material having good heat resistant, it has better heat insula(cid:173)
`tion effect, thus, an outer wall of the sucking nozzle has low
`temperature during use, and would not scald user's hand or
`mouth.
`[0049] The liquid guiding component 3 is for guiding the
`liquid smoke in the liquid smoke compartment 11 into the
`atomizing cup 22 to be atomized, and comprises the liquid
`separation seat 31 and the liquid reservoir 32. The liquid
`smoke in the liquid smoke compartment 11 is infiltrated
`through the liquid separation seat 31 and is absorbed and
`stored in the liquid reservoir 32 to be atomized. The liquid
`separation seat 31 (see FIG. 9 and FIG. 10) comprises a vent
`pipe 312 and a seat body 310 sleeved around the vent pipe
`312, and is made of silicone material. The vent pipe 312
`defines a through hole 313 in a center thereof. The seat body
`310 defines liquid guiding holes 311, and the flow volume of
`the liquid smoke depends on the size and amount of the liquid
`guiding holes 311. Referring to the directions as shown in
`FIG. 10, the seat body 310 comprises a top surface 3101 and
`a bottom surface 3102, and firmly abuts against an end of the
`liquid smoke compartment 11 inside the sucking cylinder 1 to
`seal the liquid smoke, the top surface 3101 faces the liquid
`smoke compartment 11. The vent pipe 312 correspondingly
`comprises a top end and a bottom end, and respectively com(cid:173)
`municates with the conduit 5 and the atomizing chamber 221
`to allow a flow of the smoke and air. The liquid smoke is
`atomized by the atomizer 21 and becomes fogged smoke
`which passes by the vent pipe 312 from the atomizing cham(cid:173)
`ber 221 to the conduit in order to be lead to an exterior of the
`sucking cylinder 1 or for the user to inhalation.
`[0050]
`In one embodiment, the through hole 313 passes
`through the top end and the bottom end of the vent pipe 312,
`and forms an inner edge 3120 at its inner wall. The conduit 5
`has its one end inserted into the through hole 313 by expan(cid:173)
`sion, and further abutting against the inner edge 3120, in order
`to fix said end of the conduit 5 into the vent pipe 312.
`[0051] Preferably, the vent pipe 312 and the seat body 310
`both are substantially cylindrical, and coaxial with each other
`and have a crosswise profile. The vent pipe 312 is located at a
`
`center of the seat body 310 and its opposite ends are axially
`extended. The through hole 313 is an axial hole, and the liquid
`guiding holes 311 are extended through the annular wall of
`the seat body 310 in a direction parallel to the axis of seat
`body. Preferably, the vent pipe 312 and the seat body 310 are
`integrally formed. The seat body 310 of the liquid separation
`seat 31 comprises an annular wall in which has its diameter
`larger than an annular wall of the vent pipe 312 and its height
`smaller than the vent pipe 312.
`[0052] The liquid reservoir 32 is for absorbing the liquid
`smoke infiltrated from the liquid separation seat 31, and is
`made of high temperature resistant cotton, fiberglass cotton or
`thick cotton cloth, capable of absorbing water and reserving
`water like a sponge, so that the liquid smoke can be slowly
`infiltrated into the atomizing cup 22. The liquid reservoir 32
`and the liquid separation seat 31 are fitted with each other in
`shape, and the liquid reservoir 3 2 has its top surface affixed to
`the bottom surface 3102 of the liquid separation seat 310, to
`absorb the liquid smoke flowing out of the liquid guiding hole
`311. The liquid reservoir 32 has its bottom surface affixed to
`the end of the atomizing cup 22 where the atomizer is dis(cid:173)
`posed, and opposite ends of the fiber element 212 abut against
`the bottom surface of the liquid reservoir 3 2 in order to adsorb
`the liquid smoke in the liquid reservoir 32 for facilitating the
`heating wire 211 to atomize the liquid smoke. In related
`embodiments, the liquid reservoir 32 is a cylinder with its
`outer diameter as same as that of the liquid separation seat 31,
`and defines a sleeve hole 321 at its centre, and the liquid
`reservoir 32 is sleeved around an outer wall of the bottom end
`of the vent pipe 312 via the sleeve hole 321. The liquid
`reservoir 32 can be interferentially engaged with the outer
`wall of the vent pipe 312. The liquid guiding component 3
`makes the electronic cigarette sucking rod 90 to be assembled
`conveniently, and have good drainage effect, and can prevent
`a leakage of the liquid smoke from the liquid smoke compart(cid:173)
`ment 11.
`[0053] The nozzle cover 4 is sleeved at an extremity end of
`the sucking cylinder 1, and is made of silicone material, for
`sealing the liquid smoke and fixing the conduit 5 and for
`ventilation. Its central portion defines a through hole 41 (see
`FIG. 11 and FIG. 12) where the conduit 5 is inserted, the
`through hole 41 is a straight holes or a stepped hole extended
`through the top and bottom ends of the nozzle cover 4. In the
`embodiment, the nozzle cover 4 is a stepped cylinder, and
`comprises an enlarged collar 42 with a bigger outer diameter
`and an inner cylinder 40 axially extending from the enlarged
`collar 42 and having a smaller outer diameter, and the through
`hole 41 is axially extended through the inner cylinder 40 and
`the enlarged collar 42. The inner cylinder is sleeved to an end
`of the conduit 5 opposing to the liquid guiding component 3
`in order to fix the conduit 5; the enlarged collar 42 is engaged
`with the extremity end of the sucking cylinder 1 by expansion
`and seals an end of the liquid smoke compartment 11. The
`through hole 41 is communicated with the conduit 5, to form
`a smoke passage.
`[0054] The conduit 5 is a passage to lead the fogged smoke
`generated by atomization of the liquid smoke through the
`atomizing device 2 to the exterior of the sucking cylinder 1. In
`the embodiment, the conduit 5 is formed by cutting a cyli
