In order to make the technical features, the propose and the technical effect of the present application more clearly, the specific implemental means of the present application will now be described in detail with reference to the accompanying drawings.

As shown inFIGS. 1-8, an electronic cigarette is constructed in the present application, which comprises anatomizer1, and afirst electrode2 and asecond electrode3 which are inserted in an end portion of theatomizer1. Theatomizer1 is further provided therein with an atomizingelement5 for atomizing tobacco tar, and afirst lead wire51 andsecond lead wire52 which are electrically connected to the atomizingelement5. Thesecond electrode3 has anextension part31 that extends into the interior of theatomizer1. Thesecond lead wire52 is electrically connected to theextension part31, while thefirst lead wire51 is electrically connected to thefirst electrode2. At least one first through-hole32 is defined on a side face of theextension part31.

Afirst air channel35 is defined in the interior of thesecond electrode3. The first through-hole32, thefirst air channel35 and the interior of theatomizer1 are communicated with each other to form a passage allowing airflow to pass through.

It could be understood that, thefirst lead wire51 and thesecond lead wire52 are respectively the positive wire and the negative wire led from the atomizingelement5.

The atomizingelement5 includes heating wires or an ultrasonic oscillator.

In the present application, anextension part31 extending into the interior of theatomizer1 is provided, and at least one first through-hole32 is defined on a side face of theextension part31. In this way, since the first through-hole32 for ventilation is defined on the side face of theextension part31, it is not limited to use a soldering method to connect thesecond lead wire52 to thesecond electrode3 in this case, and a clogging of the ventilation hole is prevented from occurring even though thesecond lead wire52 is connected to thesecond electrode3 by means of soldering.

Aninsulating ring34 is sleeved between thefirst electrode2 and thesecond electrode3. Aprojection21 having a shape matching with an outer shape of theinsulating ring34 is projected inwardly from thefirst electrode2. Theprojection21 is sleeved on the outside of theinsulating ring34, while theinsulating ring34 is further sleeved on the outside of thesecond electrode3. It could be understood that, theprojection21 and theinsulating ring34 are connected to each other by an interference fit, while thesecond electrode3 and the insulating ring are also connected to each other by an interference fit.

Aflange33 is formed on one end of thesecond electrode3 along an axial direction of the second electrode, and the end of the second electrode is away from theextension part31. Theflange33 is abutted against an end portion of one end of theinsulating ring34, and the end of the insulating ring is away from theextension part31.

It is possible for thesecond lead wire52 to be electrically connected to thesecond electrode3 in the following ways:

Embodiment One

As shown inFIGS. 5-8, aclamping element6 is sleeved on an end portion of theextension part31. Thesecond lead wire52 is clamped between theextension part31 and theclamping element6, and is further electrically connected to thesecond electrode3.

A blind hole is axially defined on the end portion of theextension part31. Theclamping element6 is an element having an “E”-shaped axial section matching with the blind hole. Or, thefirst air channel35 runs through two ends of thesecond electrode3, and a second through-hole communicated with thefirst air channel35 runs through theclamping element6 along an axial direction of the clamping element. The clampingelement6 is an element having an “E”-shaped axial section, and the second through-hole axially runs through the middle of the “E”-shaped element (as shown inFIG. 8 specifically).

At this time, thefirst lead wire51 is clamped between the insulatingring34 and thefirst electrode2. The clampingelement6 is made of silicone or other kinds of soft materials. It could be understood that, thesecond lead wire52 is fastened to theextension part31 via the “E”-shapedclamping element6. And the clampingelement6 is sleeved on theextension part31 by an interference fit.

It could be understood that, it is possible for the axial section of theclamping element6 to be designed in shape of a “T”. Or, a second through-hole communicated with thefirst air channel35 is defined on an end face of theclamping element6, and the axial section of theclamping element6 is in shape of a “T” with a second through-hole running therethrough in the middle.

It could be understood that, it is possible for theclamping element6 to be in various shapes, as long as thesecond lead wire52 may fixedly clamped at the end portion of theextension part31 via theclamping element6.

Embodiment Two

As shown inFIGS. 1-4, thesecond lead wire52 is connected to theextension part31 by means of soldering.

Implementing Method One: As shown inFIGS. 1-2, an end face of theextension part31 is closed, and thesecond lead wire52 is soldered to the end face of theextension part31. At this time, since thesecond lead wire52 is soldered to the end face of theextension part31, and the first through-hole32 is defined on a side face of theextension part31, a clogging of the ventilation hole will not occur since the soldering tin is at a large distance from the first through-hole32. Preferably, in this case, there are two first through-holes32.

Implementing Method Two: As shown inFIGS. 3-4, thefirst air channel35 runs through two ends of thesecond electrode3. Thesecond lead wire52 is soldered on the side face of theextension part31, and thesecond lead wire52 and the first through-hole32 are staggered from each other. In this case, a clogging of the ventilation hole will not occur, since thesecond lead wire52 and the first through-hole32 are staggered from each other.

Preferably, there is only one through-hole32 in this case. Since two ends of thefirst air channel35 are communicated with each other at this time, it is possible to guarantee the airflow volume flowing through thesecond electrode3.

In the two implementing methods of embodiment two, thefirst lead wire51 is soldered on thefirst electrode2 in each case.

In the two embodiments described above, it is possible for the first through-hole32 to be in shape of a circle, an ellipse, or a polygon. To guarantee the airflow volume, an area of each of the first through-holes32 ranges from 2 mm²to 20 mm². Besides, when thefirst air channel35 runs through two ends of thesecond electrode3, an area of a through-hole running through thefirst air channel35 in the axial direction also ranges from 2 mm²to 20 mm².

A length of a portion of theextension part31 projecting beyond the insulatingring34 ranges from 5 mm to 10 mm. In this way, a length of a portion of theextension part31 of thesecond electrode3 that is inserting into theatomizer1 will not be too long, such that thefirst lead wire51 and thesecond electrode3 will not contacted with each other by misoperation, and that a short will not be occurred between thefirst lead wire51 and thesecond electrode3.

In conclusion, the first through-hole32 is defined on the side face of the extension part31 (theextension part31 is inserted into the atomizer1) of thesecond electrode3, in such a way that thesecond wire lead52 may be connected to thesecond electrode3 in a various ways, and a clogging phenomenon will be prevented from occurring when thesecond lead wire52 is connected to thesecond electrode3 by means of soldering.
