The above structure is provided with a cavity 41, which can fully utilize the internal volume of the suction nozzle, and on the other hand, the atomizer 2 is extended and placed so that the liquid smoke storage component (not shown) in the atomizer 2 has more The large volume is used to store the electronic cigarette liquid. On the other hand, the suction nozzle 4 is provided with an internal cavity 41 to increase the volume of the smoke passage, so that the sucked smoke can be buffered before entering the user's mouth, and the smoke is mixed. The micro-liquid that has not been atomized is sufficiently condensed and adsorbed on the inner surface of the cavity 41; in addition, the tubular body 44 and the annular groove 45 are designed to allow the smoke in the smoking passage to be sucked out due to its inertia. The loop can be flowed in the annular groove 45, so that the micro-liquid which is not atomized in the smoke is collected in the annular groove 45, and is prevented from being sucked into the mouth of the electronic cigarette user to reduce the smoking taste. A sealing ring 42 is disposed between the outer wall of the atomizer 2 and the inner wall of the cavity 41 for blocking the air between the atomizer 2 and the outer tube 3 of the atomizer from entering the nozzle 4, thereby ensuring that the user of the electronic cigarette can sufficiently suck out the mist.

Most of the smoke flows into the annular groove 45 by the inertia along the inner wall of the cavity 41, and part of the smoke circulates in the annular groove, and part of the smoke is recirculated. It flows back into the cavity 41 along the outer wall of the tubular body 44, and is discharged through the smoking orifice 43. During this process, the small liquid droplets of the liquid that are not completely atomized in the smoke are condensed and accumulated on the inner wall of the cavity 41 and the outer wall of the tubular body 44, and are collected in the annular groove 45 by the air flow. This avoids direct inhalation of small droplets of smoke that are not atomized into the user's mouth. When the electronic cigarette does not work, the small droplets collected in the annular groove 45 will gradually evaporate into the air. Lost.

 [0035] As shown in FIG. 7, in the embodiment of the elliptical electronic cigarette of the present invention, the sealing ring 42 is disposed on the inner wall of the nozzle 4 and integrally formed with the nozzle 4 by the same material, when the nozzle 4 is made of soft The plastic material or the soft rubber material is made of bismuth and has the same material property as the sealing ring 42, and the two can be assimilated into an integral structure, that is, the sealing ring 42 becomes a ring convex provided on the inner wall of the cavity of the suction nozzle 4. ring.
