Both the insulating layer of the contact electrode 32 and the iron atomizing core base 33 are isolated, and the smoke oil is prevented from leaking from the bottom of the atomizer 3.

As shown in FIG. 3 and FIG. 4, the battery rod 4 side interface includes a battery rod housing 42, a first electrode needle 44, two second electrode needles 43, a magnet 45, and a grease pad 47; the lower side of the battery rod housing 42 is provided with The battery holder 46 limits the battery 41, and the upper side forms a space for accommodating the atomizer 3. In a sense, the battery rod housing 42 is also an outer casing of the electronic cigarette. After the atomizer portion is installed, The battery rod outer casing 42 directly faces the suction nozzle 1 as shown in FIG. 1; in this embodiment, the electronic cigarette is a main-shaped cigarette, and the whole is a long square smoke, and the middle cross section is a rectangle.

The left and right sides are respectively two second electrode needles 43. The second electrode needle 43 is a negative electrode (cathode) which abuts the iron atomizing core base 33 in the atomizer 3, in this embodiment, An electrode pin 44 and two second electrode pins 43 are soldered to a PCB board 49. Since the embodiment is a square cigarette, the PCB board 49 is a rectangular PCB board substantially similar to the cross section of the battery rod 4. The first electrode pin 44 is soldered to the center of the first electrode pin, and the second electrode pin 43 is welded to the symmetric side of the first electrode pin. In the embodiment, the first electrode pin 44 and the second electrode pin 43 are both elastic. The contracted metal needle also needs to be soldered on the PCB board 49 to supply two electrodes for the atomizer, wherein the anode of the electrode is connected to the first electrode needle 44, and the cathode in the electrode is connected to the two second electrode needles 43. In order to ensure that the electrodes themselves are electrically insulated from each other, the electrode pins are filled with oil barrier 47, the pad 47 in addition to the female oil barrier smoke oil leaking from the atomizer, may be electrically isolated from the first electrode and the second electrode needle 44 needle 43.
