In order to understand the technical features, purpose and the effect of the present invention more clearly, the specific embodiments of the present invention will be described referring to the drawings.

Referring toFIG. 1,FIG. 3orFIG. 6, preferred embodiment of an electronic cigarette (not labeled) is provided. The electronic cigarette includes a smoking component1, a battery rod2, and a suction nozzle3configured at an end of the smoking component1and far away from the battery rod2. A receiving chamber101is defined in the smoking component1, and the receiving chamber101includes an atomizer base14separating the receiving chamber101into an atomized cavity13and a cavity16.

The diameter of the first connecting portion36is less than that of the main body35, and the first connecting portion36has a first groove33. The sleeve5is sleeved on the first connecting portion36, and a channel surrounded by the sleeve5and the first groove33is defined as a first passage104. The first passage104communicates with the cavity16and the air inlet32to cooperatively form the second airflow channel103.

A second method of embodiment 1:

The smoking component1includes a sleeve5. The suction nozzle3includes a main body35and a first connecting portion36axially extended toward the battery rod2. The diameter of the first connecting portion36is less than that of the main body35. The inner wall of the sleeve5has a second groove34, and the first connecting portion36is inserted in the sleeve5, thereby a channel surrounded by the first connection portion36and the second groove34is defined as a second passage105. The second passage105communicates with the cavity16and the air inlet32to form the second airflow channel103.

The difference between the first and second methods of embodiment 1 is that the first groove33is defined at the first connecting portion36in the first method while the second groove34, its function is same as the first groove33, is defined at the inner wall of the sleeve5.

It is to be understood that a cross-section shape of the first groove33or the second groove34can be any of square, semicircle, triangle, or rectangle. And the first groove33or the second groove34can be axially defined at the first connecting portion36or the sleeve5along a straight line or along a curve.

The air inlet32is a first notch, which is defined on the suction nozzle3and communicates with the first groove33or the second groove34.

In the illustrated embodiment, the first groove33or the second groove34is preferred axially defined at the first connecting portion36or the sleeve5along a straight line, and the cross-section shape of the first groove33or the second groove34is rectangle. The air inlet32is preferred defined on the adjacent edge area of the main body35and the first connecting portion36, and the first notch is rectangular.

In the illustrated two methods of embodiment 1, the second airflow channel103is defined either through the sleeve5or the first connection portion36of the suction nozzle3. Also the suction nozzle3is axially extended to the cavity16in the two methods. It is to be understood that the suction nozzle3is at least extended to the edge of the atomizer base14, which is adjacent to the cavity16.

Referring toFIG. 3andFIG. 4, the air inlet32is a through hole, which is radially through the suction nozzle3into the cavity16, and the second airflow channel103is formed by the air inlet32and the cavity16communicating with each other. The suction nozzle3axially extends to or beyond the cavity16.

In the illustrated embodiment 2, a sleeve is not needed, the suction nozzle13axially extends to or beyond the cavity16to play the role of the sleeve5in the first embodiment, and the atomized cavity13and the atomizer base14are both located inside the suction nozzle3. The air outlets31can be axially or radially defined on an end of the suction nozzle3, and the end is far away from the battery rod2.

In the first embodiment, there can be one or more second passages105. In both the first and second embodiment, there can be one or more air inlets32. Usually, for the uniformity of the atomized smoke, two second passages105and two air inlets32are symmetrically defined in the electronic cigarette.

In the first embodiment, the cavity16is defined in the sleeve5, while the cavity16is defined in the suction nozzle3in the second embodiment. It is to be understood that the cavity16can be defined in other components.

In the present invention, referring toFIG. 1andFIG. 3, the electronic cigarette further includes a second connecting portion40connecting the smoking component1and the battery rod2. The second connecting portion40includes an upper connecting portion41and a lower connecting portion42. The upper connecting portion41has an inserting portion15inserted in the smoking component1. The end of the inserting portion15contacts with an end of the atomizer base14. It is to be understood that the cavity16is a cavity surrounded by the upper connecting portion41and the end of the atomizer base14.

The inserting portion15has a first through-hole18on the circumference thereof. In the first embodiment, the cavity16is communicated with the air inlet32via the first through-hole18and the first104or second passage105in the first or second methods. In the second embodiment, the first through-hole18is configured to correspond to and communicate with the air inlet32, preferably the central axis of the first through hole18and the air inlet32is same. The air inlet32, the first through-hole18and the cavity16are communicated with each other and cooperatively form the second airflow channel103.

It is to be understood that a second notch can be defined at the edge of the inserting portion15contacting with the end of the atomizer base14, thereby the second notch and the end of the atomizer base14cooperatively form the first through-hole18. The shape of the first through-hole18can be selected according to need, such as circle, triangle, or square.

Preferably, the shape of the second notch is rectangle, so that it is easy to manufacture.

When there is the inserting portion15, the periphery of the end of the inserting portion15contacting the atomizer base14has an annular recess106, which can store certain air to providing a buffer zone before the air entering the cavity16, the airflow flows from the air inlet32, though the first through hole18, and then into the cavity16. Thereby it keeps the continuity of the air during inhaling.

In the present invention, the cross-sectional area of the first through-hole18, air inlet32, air outlet31, first groove33, or second groove34is 2-7 mm2, which ensures the air flow quantity and velocity during inhaling.

In the present invention, the suction nozzle3can extend into the cavity16, thereby the length of the sleeve5can be reduced or can be omitted, which is easy to manufacture and install.

In the present invention, the airflow channel is formed via the air inlet32defined in the suction nozzle3communicating with the first groove33or the second groove34, or just a through-hole defined on the suction nozzle3, which is easy to manufacture. The airflow channel is located inside the smoking component1and communicates with the air inlet32and air outlet31, which avoids that the hot atomized smoke flows back into the battery rod2, therefore the batteries in the battery2are protected from being damaged.
