SPECIFIC EMBODIMENT

The present invention is further described below with reference to accompanying drawings and embodiments.

Referring to FIGS. 1 to 3, an electronic cigarette 100 according to the present invention includes a cylindrical hollow atomizing stem 10, a first conductive ring 20 sleeved at the bottom of said atomizing stem 10 and airproof with the atomizing stem 10 by using a leakproof rubber ring 50, a second conductive ring 30 arranged in said first conductive ring 20 and insulated from the first conductive ring 20 by an insulation ring 60, a conduit 40 held in said atomizing stem 10, with base contacting said first conductive ring 20 tightly, a liquid blocker 70 arranged on the top of the atomizing stem 10, and a cigarette holder 80 arranged on the top of the atomizing stem 10 simultaneously and holding the liquid blocker 70 therein. The cigarette holder 80 also serves as a mouthpiece of the electronic cigarette 100.

One feature of the electronic cigarette according to the present invention lies in that, the inner wall of said atomizing stem 10, the outer wall of said conduit 40, the top of said first conductive ring 20, and the bottom of said liquid blocker 70 together confine a liquid storage chamber 12 for storing tobacco juice therein. This liquid storage chamber 12, because of its good seal from other components of the electronic cigarette 100, can store tobacco juice without cigarette cotton, so the structure of the electronic cigarette 100 is greatly simplified as compared with a structure of the prior art.

Referring to FIGS. 1-2, the conduit 40 includes a first segment 41 and a second segment 42 in communication with the first segment 41; the first segment 41 extends from an end of the second segment 42, away from the cigarette holder 80, and the second segment 42 is between the cigarette holder 80 (or the mouthpiece) and the first segment 41; the first segment 41 has a first transverse inner dimension, and the second segment 42 has a second transverse inner dimension; in one embodiment as shown in FIGS. 1-2, first transverse inner dimension of the first segment 41 is an inner dimension W along a transverse direction 300 inside the first segment 41, and second transverse inner dimension of the second segment 42 is an inner dimension N along the transverse direction 300 inside the second segment 42; the inner dimension W is larger than the inner dimension N. In other words, and according to FIGS. 1 and 2, the inner space 44 within the first segment 41 along the transverse direction 300 is wider than the inner space 45 inside the second segment 42 along the transverse direction 300. The first segment 41 has a first transverse outer dimension, and the second segment 42 has a second transverse outer dimension, referring to FIG. 2, in one embodiment, an outer dimension OW1 of the first segment 41 along the transverse direction 300 is the first transverse outer dimension, and an outer dimension OW2 of the second segment 42 along the transverse direction 300 is the second transverse outer dimension, and OW1 is larger than OW2. Further referring to FIGS. 1-2, the first segment 41 has an axis 311 along a longitudinal direction 310, and the second segment 42 has an axis 312 along the longitudinal direction 310 of the second segment 42, and the axis 311 and the axis 312 either_overlap or both extend along the longitudinal direction 310. The length L1 of the first segment 41 is shorter than the length L2 of the second segment 42, measuring from an end of the first segment 41. In one embodiment, the second segment 42 can further extends into the first segment 41 by a section 400 as indicated in FIG. 2.

Another feature of the electronic cigarette according to the present invention lies in that, the electronic cigarette 100 further includes a fiber rope 90, wherein two end portions of said fiber rope 90 are placed within the liquid storage chamber 12, and a middle portion thereof passes transversally through said conduit 40 and is held inside first segment 41 of the conduit 40. In addition, a portion of said fiber rope 90 that is held within the first segment 41 of the conduit 40 (i.e., the middle portion) is wrapped with a heating wire 102, as a heating device 103, so that when tobacco juice is injected into said liquid storage chamber 12, the tobacco juice is automatically adsorbed into the fiber rope 90, and when the heating wire 102 is energized, the heating wire 102 atomizes the tobacco juice adsorbed in the fiber rope 90. In this embodiment, the heating wire 102 serves as an atomizer. This atomizing method has a high atomizing speed and generates more smoke as compared with the prior art.

Preferably, said first conductive ring 20 is provided at the bottom with a battery compartment 22, and at the top with a mounting hole (not identified) in communication with said battery compartment 22, wherein said second conductive ring 30 is mounted within the mounting hole, and said second conductive ring 30 is longitudinally provided with a flow-guiding hole 32 therein. Further, said insulation ring 60 is arranged between said first conductive ring 20 and said second conductive ring 30.

The two ends of said heating wire 102 are electrically connected to the first conductive ring 20 and the second conductive ring 30, respectively. When a battery is mounted in the battery compartment 22, positive and negative poles of the battery is respectively connected to said first and second conductive rings 20 and 30, so that the heating wire 102 is energized and thus provides heat, thereby quickly atomizing tobacco juice in the fiber rope 90.

Said liquid blocker 70 includes a body portion 72 and a flange 74 formed at the bottom of the body portion 72, wherein said flange 74 seals said liquid storage chamber 12, thereby preventing tobacco juice in the liquid storage chamber 12 from flowing backwards. The body portion 72 of said liquid blocker 70 is provided with a longitudinal hole 76 in communication with an interior of the conduit 40 and a transverse hole 78 in communication with the longitudinal hole 76. In addition, a gap 83 is formed between two side edges at the top of the body portion 72 and the inner wall of said cigarette holder 80.

An air flow hole 82 in communication with said transverse hole 78 is formed inside said cigarette holder 80.

A working procedure of the electronic cigarette 100 according to the present invention is described below. Referring to FIGS. 1 to 3, the heating wire 102 is heated up to produce a high temperature, thereby atomizing tobacco juice in the fiber rope 90. When a user sucks the electronic cigarette 100 from the cigarette holder 80, air outside the battery compartment 22 flows through the flow-guiding hole 32 into the conduit 40, and when flowing upwards, the external air carries smoke generated by atomizing the tobacco juice to flow. The mixed air flow goes through the conduit 40, i.e., traveling from the first segment, through the second segment, and then flows into the air flow hole 82 inside the cigarette holder 80 through the longitudinal hole 76, the transverse hole 78, and the gap 83, and is finally inhaled by the user.

FIGS. 4 to 7 illustrate a procedure of filling tobacco juice into the liquid storage chamber 12. Firstly, the cigarette holder 80 is removed from the electronic cigarette 100. Then, the liquid blocker 70 is removed. The electronic cigarette is inclined at a certain angle, and then tobacco juice is poured from a bottle 200 into the liquid storage chamber 12. After that, the liquid blocker 70 and the cigarette holder 80 are mounted one by one, thereby completing the procedure of filling tobacco juice.

An integral design is realized for a heating unit and a tobacco juice storage unit of the electronic cigarette according to the present invention, the overall structure uses a vacuum-simulation design, no cigarette cotton is required for guiding a flow between the tobacco juice storage unit and the heating unit, and the atomizing effect is obviously improved, so that a generated air flow may better meet requirements of an electronic cigarette, the taste is more close to a true cigarette, and at the same time tobacco juice is sealed for storage, and a validity duration of the tobacco juice is greatly increased; in addition, the overall structure of the electronic cigarette is simplified, manufacturing cost is reduced, and production efficiency is improved.

The components of the electronic cigarette according to the present invention are not connected by welding, which effectively avoids pollution of soldering tin and soldering flux, thereby making it more environmental-friendly and hygienic.

The liquid blocker, the cigarette holder, and the body of the electronic cigarette according to the present invention are detachably connected, and after the tobacco juice is depleted, refilling can be performed, thereby prolonging the service life of the electronic cigarette.

The embodiment mentioned above is a preferable embodiment of the present invention, but is not intended to limit the present invention. Any other changes, modifications, replacements, combinations, and simplifications made without departing from the spiritual essence and principle of the present invention are within the scope of the present invention.
